Description

Tension control equipment and hosepipe production line

Technical Field

The application relates to the technical field of tension control equipment, in particular to tension control equipment and a water hose production line.

Background

The water hose is generally applied to the fields of drainage, irrigation, fire protection and the like, and has different dimension specifications and different water pressure resistance so as to meet the requirements of different application occasions.

In order to enable the water pressure resistance of the water hose to meet design expectations, the density of yarns in the water hose can be increased on one hand, and the tension of the yarns in the water hose can be increased on the other hand. Increasing the yarn density causes an increase in the consumption of yarn, which in turn increases the production costs of the hose. In the water band, under the condition of the design density of the yarns, the yarn tension is increased, so that the water pressure resistance of the water band can be improved under the condition of not increasing the consumption of the yarns. However, if the tension of the yarn is too high, the yarn is stretched, which leads to production accidents and influences the product quality of the water hose. Therefore, in the production process of the water belt, the yarn tension needs to be controlled so that the yarn tension meets the production requirement of the water belt with corresponding specification.

In the existing water band production equipment, the tension of yarns in the water band is controlled by controlling the traction force of the rear section of the water band production line, so that the production beat of the water band can be influenced, the production requirements of the water bands with different specifications cannot be met, the tension of the yarns is difficult to monitor and adjust in real time, and the produced water band products are uneven in quality.

In some embodiments of the present application, the present application proposes a hose production line, including a tension control device 100 that the present application proposes, the tension control device 100 is installed in the feed end of the yarn in the hose production line, and the tension control device 100 is due to controlling the tension of the yarn in the hose production line.

Referring to fig. 1 to 3, in some embodiments of the present application, a tension control apparatus 100 according to the present application includes: the tension sensor comprises a mounting frame 10, a tension roller 20, a tension control mechanism 30, a brake mechanism 40 and a tension detection mechanism 50.

The mounting bracket 10 both sides all are provided with a plurality of fender position grooves 11, and every fender position groove 11 all is provided with a plurality of draw-in grooves 12, and draw-in grooves 12 one-to-one of mounting bracket 10 both sides to corresponding draw-in grooves 12 align each other.

The clamping blocks 21 are fixedly arranged at the two ends of the tension roller 20, the clamping blocks 21 are matched with the clamping grooves 12, the tension roller 20 is arranged on the mounting frame 10 by respectively clamping the clamping blocks 21 at the two ends into the clamping grooves 12 at the two sides of the mounting frame 10, and the tension roller 20 and the mounting frame 10 do not rotate relatively.

The tension control mechanism 30 comprises a press roller assembly 31 and a guide roller assembly 32, wherein the guide roller assembly 32 is rotatably arranged on the mounting frame 10, and in operation, the press roller assembly 31 presses yarns against the guide roller assembly 32.

The brake mechanism 40 is used for controlling the rotating speed of the guide roller assembly 32, and the brake mechanism 40 is connected with the guide roller assembly 32.

The tension detecting mechanism 50 comprises a tension sensor 51 and a driving roller 52, wherein the tension sensor 51 is fixedly arranged on two sides of the mounting frame 10, and the tension sensor 51 is respectively and rotatably connected with two ends of the driving roller 52.

Wherein all tension rollers 20 are located upstream of the tension control mechanism 30 and the tension detection mechanism 50 is located downstream of the tension control mechanism 30.

In the water belt production process, the tension detection mechanism 50 is used for detecting the yarn tension in the production process in real time, the tension control mechanism 30 is used for enabling the yarn tension to be in a controllable state, the brake mechanism 40 is used for controlling the rotating speed of the guide roller assembly 32 in the tension control mechanism 30 to regulate and control the yarn tension, and therefore the tension in the water belt is kept stable and meets design expectations.

When the produced water band is subjected to model change, the yarn tension meets the design requirement of the water band with the corresponding model by adjusting the positions and the number of the tension rollers 20.

Therefore, the tension of the yarns is effectively controlled in the water hose production process, so that the water hose production line can meet the production requirements of water hoses with different specifications, and the product quality of the water hose can meet the design expectation.

Referring to fig. 1 to 3, in some application scenarios of the present application, after a yarn is drawn into the tension control apparatus 100, the yarn passes between a plurality of tension rollers 20, so that each tension roller 20 in the tension control apparatus 100 contacts the yarn and forms a certain wrap angle. According to the production demand of different model hosepipes, through adjusting the quantity of tension roller 20 and the mounted position of each tension roller 20, and then set up yarn tension, make yarn tension satisfy the design demand of corresponding model hosepipe.

It will be appreciated that the wrap angle of the yarn to the tension roller 20 will be different and the contact length of the yarn with the tension roller 20 will be different. The longer the contact length between the yarn and the tension roller 20, the greater the friction between the yarn and the tension roller 20, and the greater the tension generated in the yarn by the tension roller 20. Accordingly, the tension of the yarn can be adjusted by adjusting the wrap angle of the yarn to the tension roller 20.

Adjusting the number of tension rolls 20 adjusts the total contact length between all tension rolls 20 and the yarn. When the relative position between the adjacent tension rollers 20 is unchanged, the greater the number of tension rollers 20, the longer the total contact length between all tension rollers 20 and the yarn, and the greater the tension that the tension rollers 20 produce in the yarn. Accordingly, the tension of the yarn can be adjusted by adjusting the number of the tension rollers 20.

Adjusting the relative position between adjacent tension rolls 20 adjusts the wrap angle of the yarn to tension roll 20, and when the distance between adjacent tension rolls 20 in the direction of yarn movement is smaller, the wrap angle of the yarn to tension roll 20 is larger, the contact length between the yarn and the individual tension rolls 20 is longer, and the tension roll 20 causes the tension generated in the yarn to be larger. The greater the distance between adjacent tension rolls 20 in the direction perpendicular to the yarn, the greater the wrap angle of the yarn to the tension rolls 20, and the longer the contact length between the yarn and the individual tension rolls 20, the greater the tension in the yarn by the tension rolls 20. Accordingly, the tension of the yarn can be adjusted by adjusting the installation position of the tension roller 20.

The clamping blocks 21 at two ends of the tension roller 20 are respectively clamped into the clamping grooves 12 at two sides of the mounting frame 10 to mount the tension roller 20 on the mounting frame 10, and the clamping grooves 12 at two sides of the mounting frame 10 are in one-to-one correspondence and the corresponding clamping grooves 12 are mutually aligned due to different positions of the clamping grooves 12 at the same side of the mounting frame 10, so that the mounting positions of the tension roller 20 can be adjusted by mounting the tension roller 20 in the clamping grooves 12 at different positions. When the shape of the clamping groove 12 is non-circular or non-circular, the tension roller 20 and the mounting frame 10 cannot rotate relatively, so that friction between the yarn and the tension roller 20 is sliding friction, and the tension roller 20 can effectively increase the tension of the yarn.

Illustratively, the shape of the card slot 12 may be a polygonal slot (e.g., the cross-sectional shape of the card slot 12 is a square slot) or an elliptical slot. The cross-sectional shape of the clamping blocks 21 at the two ends of the tension roller 20 is matched with the shape of the clamping groove 12, so that after the clamping blocks 21 at the two ends of the tension roller 20 are clamped into the clamping groove 12, the tension roller 20 does not play, and is stably and relatively fixed with the mounting frame 10. Of course, the tension roller 20 can also be connected by screws, pins or buckles so that the tension roller 20 does not play and is stably fixed relative to the mounting frame 10.

Referring to fig. 5, after passing through all of the tension rollers 20, the yarn enters the tension control mechanism 30 and passes between the pressure roller assembly 31 and the guide roller assembly 32. The press roller assembly 31 presses the yarn against the guide roller assembly 32, increases the pressure of the yarn on the press roller assembly 31 while increasing the wrap angle between the yarn and the press roller assembly 31, and produces pressure on the yarn through the press roller assembly 31, and causes the yarn and the press roller assembly 31 to generate a certain wrap angle. In this way, the yarn is placed in tension-adjustable condition within the tension control mechanism 30.

It will be appreciated that when the guide roller assembly 32 is freely rotatable at the mounting frame 10, the friction between the yarn and the guide roller assembly 32 drives the guide roller assembly 32 to rotate when the yarn passes the guide roller assembly 32, at this time, the linear velocity of the contact portion of the guide roller assembly 32 with the yarn is equal to the moving velocity of the yarn, the friction between the yarn and the guide roller assembly 32 is rolling friction, at this time, the friction between the guide roller assembly 32 and the yarn is minimum, and thus the guide roller assembly 32 minimizes the tension added to the yarn.

When the rotation of the guide roller assembly 32 is controlled, there is a difference between the linear velocity of the guide roller assembly 32 where it contacts the yarn and the moving velocity of the yarn.

When the rotational speed of the guide roller assembly 32 increases, if the normal line of the rotational direction of the guide roller assembly 32 is directed in the moving direction of the yarn, and at this time, the linear speed of the guide roller assembly 32 at the contact point with the yarn is greater than the moving speed of the yarn, the guide roller assembly 32 pulls the yarn in the moving direction of the yarn, and the guide roller assembly 32 reduces the tension of the yarn.

When the rotational speed of the guide roller assembly 32 is reduced, if the normal line of the rotational direction of the guide roller assembly 32 is directed in the moving direction of the yarn, and at this time, the linear speed of the guide roller assembly 32 at the contact point with the yarn is lower than the moving speed of the yarn, sliding friction is generated between the guide roller assembly 32 and the yarn, and the tension of the yarn is increased by the guide roller assembly 32.

When the rotational speed of the guide roller assembly 32 is continuously reduced, even when the normal line of the rotational direction of the guide roller assembly 32 is deviated from the moving direction of the yarn, the sliding friction between the guide roller assembly 32 and the yarn is continuously increased, and thus the tension of the yarn is continuously increased. When the sliding friction between the guide roller assembly 32 and the yarn increases to be equal to the traction force of the external device on the yarn, the tension of the yarn reaches the maximum, and at this time, if the guide roller assembly 32 rotates reversely in the direction of the normal line of the rotation direction of the guide roller assembly 32 away from the movement direction of the yarn, and the rotation speed of the guide roller assembly 32 increases, the sliding friction between the guide roller assembly 32 and the yarn will be greater than the traction force of the external device on the yarn, and at this time, the guide roller assembly 32 will pull the yarn to move reversely.

It should be noted that the above force analysis between the guide roller assembly 32 and the yarn is a theoretical analysis under ideal conditions. In some practical applications of the present application, the guide roller assembly 32 is rotated by the yarn. The present application also proposes that the guide roller assembly 32 is connected to a brake mechanism 40, the brake mechanism 40 being used to control the rotational speed of the guide roller assembly 32, such that the rotational speed of the guide roller assembly 32 is only reduced or stopped and the direction is not changed. In this manner, the rotational speed of the guide roller assembly 32 can be controlled by the brake mechanism 40 to increase the tension of the yarn. As the amount by which the brake mechanism 40 controls the rotational speed of the guide roller assembly 32 increases, the yarn tension increases.

Referring to fig. 3 and 5, in other application scenarios of the present application, a power mechanism may be added to the guide roller assembly 32 to drive the guide roller assembly 32 to rotate, so that the guide roller assembly 32 can actively rotate instead of being driven to rotate by yarn. In this application scenario, the rotation speed of the guide roller assembly 32 may be greater than the movement speed of the yarn, and the rotation direction of the guide roller assembly 32 may also be changed, thereby increasing the adjustment range of the yarn tension.

After the yarn is pulled out from the tension control mechanism 30, the yarn enters the tension detection mechanism 50, contacts with the driving roller 52, and forms a certain wrap angle, at this time, the yarn drives the roller 52 to generate pressure, and the driving roller 52 produces pressure on the tension sensor 51. The tension sensor 51 detects the tension of the yarn when it receives the pressure from the driving roller 52. If the tension detecting mechanism 50 detects that the tension of the yarn fluctuates, the rotating speed of the guide roller assembly 32 is controlled by the braking mechanism 40, and then the tension of the yarn is regulated and controlled by the tension control mechanism 30, so that the tension of the yarn is kept in a stable state.

Therefore, the production line of the water hose can adapt to the production of water hoses with different specifications through the tension roller 20 and the gear groove 11, and the tension of yarns is monitored and regulated in real time through the tension control mechanism 30, the brake mechanism 40 and the tension detection mechanism 50, so that the tension of the yarns is stably kept within a design expected range, and the product quality of the water hose meets the design expectation.

Referring to fig. 1 to 3 and 5, in particular, in some embodiments of the present application, the platen roller assembly 31 includes a platen roller 311 and a turret 312. The rotating frame 312 is rotatably mounted to the mounting frame 10, and the crimping rollers 311 are rotatably mounted to the rotating frame 312. The guide roller assembly 32 includes a first guide roller 321, the first guide roller 321 is rotatably mounted to the mounting frame 10, and the brake mechanism 40 is connected to the first guide roller 321. Wherein the rotating frame 312 can make the roller wall of the crimping roller 311 contact with the roller wall of the first guiding roller 321.

The yarn passes between the pressing roller assembly 31 and the guide roller assembly 32, contacts the first guide roller 321 and forms a certain wrap angle. The rotating frame 312 is rotated to make the yarn pressing roller 311 approach the first guiding roller 321, and the yarn is pressed against the first guiding roller 321 by the yarn pressing roller 311, so that enough friction force is generated between the first guiding roller 321 and the yarn to increase the tension of the yarn. The rotation speed of the first guide roller 321 is regulated and controlled by the brake mechanism 40, so that the tension of the yarn is controlled.

In this way, the tension control mechanism 30, the brake mechanism 40 and the tension detection mechanism 50 monitor and regulate the tension of the yarn in real time, so that the tension of the yarn is stably maintained within the design expected range, and the product quality of the water hose meets the design expected.

It should be noted that, when the yarn at the first guiding roller 321 is to be finished or inspected, the rotating frame 312 may be rotated, so that the thread pressing roller 311 is far away from the first guiding roller 321, and the thread pressing roller 311 is further released from pressing the yarn, and a space is reserved for a worker to finish or inspect the yarn conveniently.

Referring to fig. 1 to 3, further, in some embodiments of the present application, the guide roller assembly 32 further includes a second guide roller 322, the rotating frame 312 may make the roller wall of the wire pressing roller 311 contact with the roller walls of the first guide roller 321 and the second guide roller 322 at the same time, and the brake mechanism 40 is connected to the first guide roller 321 and the second guide roller 322 at the same time.

When the yarn passes through the space between the compression roller assembly 31 and the guide roller assembly 32, the yarn is contacted with the first guide roller 321 and the second guide roller 322 at the same time and forms a certain wrap angle at the first guide roller 321 and the second guide roller 322 respectively, and the rotating frame 312 is rotated to ensure that the roller wall of the yarn pressing roller 311 is contacted with the roller walls of the first guide roller 321 and the second guide roller 322 at the same time, so that the wrap angle of the yarn to the first guide roller 321 and the second guide roller 322 can be increased, the yarn pressing roller 311 is provided with a certain wrap angle, and the increase of the yarn tension is further increased. The braking mechanism 40 simultaneously controls the rotation speeds of the first guide roller 321 and the second guide roller 322, and further adjusts the tension of the yarn by adjusting the rotation speeds of the first guide roller 321 and the second guide roller 322.

Thus, the regulating range of the tension control mechanism 30 for regulating and controlling the yarn tension is widened, and the regulating and controlling capability of the tension control mechanism 30 is improved.

Referring to fig. 3 to 4, in particular, in some embodiments of the present application, the brake mechanism 40 includes a magnetic powder clutch 41 and a transmission assembly 42, and the magnetic powder clutch 41 is fixedly mounted to the mounting frame 10. The magnetic particle clutch 41 is connected to the guide roller assembly 32 by a speed changing assembly 42, and the speed changing assembly 42 makes the rotating speed of the magnetic particle clutch 41 be higher than the rotating speed of the guide roller assembly 32.

The guide roller assembly 32 is braked by the magnetic powder clutch 41, and the rotating speed of the guide roller assembly 32 is regulated. The speed change is performed by the speed change assembly 42, which is that the rotational speed at the magnetic powder clutch 41 is greater than the rotational speed at the guide roller assembly 32. When the magnetic particle clutch 41 is braked, the amount of change in the rotational speed at the magnetic particle clutch 41 is also larger than the amount of change in the rotational speed at the guide roller assembly 32.

In this manner, the braking effect of the magnetic particle clutch 41 on the guide roller assembly 32 is satisfied by the transmission assembly 42 as desired.

Referring to fig. 2-4, in some embodiments of the present application, the transmission assembly 42 includes: a first transmission shaft 421, a first small diameter gear 424, a second transmission shaft 422, a third transmission shaft 423, a second small diameter gear 425, a first large diameter gear 426, and a second large diameter gear 427.

The first transmission shaft 421 is rotatably installed at the mounting frame 10, and one end of the first transmission shaft 421 is connected to the input end of the magnetic powder clutch 41. The first small diameter gear 424 is mounted to an end of the first transmission shaft 421 remote from the magnetic powder clutch 41. The second transmission shaft 422 is rotatably mounted on the mounting frame 10, a first large-diameter gear 426 is mounted at one end of the second transmission shaft 422, a second small-diameter gear 425 is mounted at the other end of the second transmission shaft 422, and the first large-diameter gear 426 is meshed with the first small-diameter gear 424. The third transmission shaft 423 is rotatably installed on the installation frame 10, one end of the third transmission shaft 423 is provided with a second large-diameter gear 427, and the second large-diameter gear 427 is meshed with the second small-diameter gear 425;

wherein the pitch diameter of the first small diameter gear 424 is smaller than the pitch diameter of the first large diameter gear 426. The pitch diameter of the second small diameter gear 425 is smaller than the pitch diameter of the second large diameter gear 427. The pitch diameter of the first large diameter gear 426 is greater than the pitch diameter of the second small diameter gear 425.

When the yarn drives the guide roller assembly 32 to rotate, the rotating guide roller assembly 32 drives the magnetic powder clutch 41 to rotate through the speed changing assembly 42. In this process, the rotating guide roller assembly 32 drives the second large diameter gear 427, and since the second large diameter gear 427 is meshed with the second small diameter gear 425 and the pitch diameter of the second small diameter gear 425 is smaller than that of the second large diameter gear 427, the transmission of the second large diameter gear 427 and the second small diameter gear 425 assembly is represented as a speed increasing transmission. Because the second small diameter gear 425 is coaxial with the first large diameter gear 426, the pitch diameter of the first large diameter gear 426 is larger than that of the second small diameter gear 425, and therefore, the transmission of the assembly of the second small diameter gear 425 and the first large diameter gear 426 is also represented as speed-increasing transmission. The first large diameter gear 426 is meshed with the first small diameter gear 424, and the pitch diameter of the first small diameter gear 424 is smaller than that of the first large diameter gear 426, so that the transmission of the assembly of the first large diameter gear 426 and the first small diameter gear 424 is a speed-increasing transmission. The input end of the magnetic powder clutch 41 is connected with the first small diameter gear 424 and the first transmission shaft 421, so that the rotational speed of the magnetic powder clutch 41 is greater than the rotational speed of the guide roller assembly 32 after the rotation of the guide roller assembly 32 is transmitted through the speed change assembly 42. When the magnetic particle clutch 41 is braked, the amount of change in the rotational speed at the magnetic particle clutch 41 is also larger than the amount of change in the rotational speed at the guide roller assembly 32. In this manner, the braking effect of the magnetic particle clutch 41 on the guide roller assembly 32 is satisfied by the transmission assembly 42 as desired.

Referring to fig. 2 to 3, in some embodiments of the present application, a transmission gear 428 is mounted at an end of the third transmission shaft 423 remote from the second large diameter gear 427, and an output gear 323 is mounted at an output end of the guide roller assembly 32. A chain 429 is arranged between the output gear 323 and the transmission gear 428, and the output gear 323 and the transmission gear 428 are meshed with the chain 429. When the guide roller assembly 32 rotates, the transmission gear 428 is driven to rotate by the chain 429 so as to drive the third transmission shaft 423 to rotate, and the speed changing assembly 42 is driven to operate.

The guide roller assembly 32 drives the speed changing assembly 42 to operate in a gear chain 429 transmission mode, so that the input end of the magnetic powder clutch 41 rotates. When the rotational speed of the guide roller assembly 32 needs to be reduced and regulated, the magnetic powder clutch 41 acts, and the speed of the guide roller assembly 32 is regulated and regulated through the transmission of the speed changing assembly 42, the output gear 323 and the chain 429. The transmission structure is stable and reliable.

Referring to fig. 5, in some embodiments of the present application, the gear grooves 11 of the side portion of the mounting frame 10 are sequentially arranged along the moving direction of the yarn, and the card slot 12 in each gear groove 11 is arranged perpendicular to the moving direction of the yarn.

The clamping blocks 21 at two ends of the tension roller 20 are respectively clamped into the clamping grooves 12 at two sides of the mounting frame 10 to mount the tension roller 20 on the mounting frame 10, and the clamping grooves 12 at two sides of the mounting frame 10 are in one-to-one correspondence and the corresponding clamping grooves 12 are mutually aligned due to different positions of the clamping grooves 12 at the same side of the mounting frame 10, so that the mounting positions of the tension roller 20 can be adjusted by mounting the tension roller 20 in the clamping grooves 12 at different positions.

Therefore, the hose production line can adapt to the production of the hoses with different specifications through the tension roller 20 and the gear groove 11.

Referring to fig. 2 and 6, the cross section of the clamping block 21 at two ends of the tension roller 20 is square, the shape of the clamping groove 12 is square, and the shape of the clamping block 21 is matched with the shape of the clamping groove 12.

The cross-sectional shape of the clamping blocks 21 at the two ends of the tension roller 20 is matched with the shape of the clamping groove 12, so that after the clamping blocks 21 at the two ends of the tension roller 20 are clamped into the clamping groove 12, the tension roller 20 does not play, and is stably and relatively fixed with the mounting frame 10. When the tension roller 20 does not rotate, the friction force between the yarn and the tension roller 20 is a sliding friction force, so that the tension roller 20 can effectively increase the tension of the yarn.

In some embodiments of the present application, a branching plate 60 is provided at the top of the mounting frame 10, and the branching plate 60 is provided with a plurality of branching holes 61, and the branching holes 61 are arranged along the axial direction of the tension roller 20.

When the yarn enters the tension control apparatus 100, the yarn is uniformly distributed along the axial direction of the tension roller 20 by the dividing plate 60, so that the stress of each yarn at the tension roller 20 is the same. Therefore, the tension of each strand of yarn in the water band is more uniform, and the product quality of the water band is improved.
