For the specific structure of the packaging chute and other accessory components in the strapping machine, reference may be made to the configuration of the conventional strapping machine, which is not limited or described in detail herein.
In order to meet the requirements for easy assembly and disassembly and improved reliability in use, the strapping head is improved as follows.
As shown in fig. 1 to 7, the head for a strapping machine of the present embodiment includes:
the device comprises a mounting base 1, a guide belt groove 11 is arranged at one end part of the mounting base 1, a sliding seat 12 capable of sliding is arranged at the other end part of the mounting base 1, and a first driving mechanism 13 for driving the sliding seat 12 to reciprocate is further arranged on the mounting base 1;

the strapping band delivered by the band feeding mechanism 21 enters the guide band slot 11 and is delivered from the guide band slot into the sealing mechanism 22.
Specifically, in the actual assembly process, the tape feeding mechanism 21 and the sealing mechanism 22 are assembled together to form the head body 2, and the head body 2 is mounted on the slide base 12 on the mounting base 1 as an integral layout to complete the assembly of the head for the strapping machine.
In use, the tape feeding mechanism 21 is used for driving a packing tape entering the strapping head to move, the packing tape enters the tape feeding mechanism 21 from the tape inlet 201, the packing tape is driven by the tape feeding mechanism 21 to be output from the tape outlet 202 and enter the guide tape slot 11, and the packing tape enters the sealing mechanism 22 under the guiding action of the guide tape slot 11. The strapping band can be transported out via the sealing mechanism 22 into the packaging chute and finally again into the sealing mechanism 22.
The sealing mechanism 22 can then weld and cut the strapping band, and in order to achieve tensioning of the strapping band, a cutting element 221 and a welding element 222 are provided in the sealing mechanism 22, the welding element 222 being used for welding the strapping band, and the cutting element 221 being used for cutting the strapping band. For concrete representation entities of the cutting element 221 and the welding element 222 configured in the sealing mechanism 22, reference may be made to structural design in a conventional strapping head, which is not described or limited herein.
Meanwhile, in order to meet the requirement of tightening the strapping band, the sealing mechanism 22 further comprises a first clamping mechanism 223, a second clamping mechanism 224 and a third clamping mechanism 225, and the first clamping mechanism 223, the second clamping mechanism 224 and the third clamping mechanism 225 are used for clamping the strapping band. The specific entities of the first clamping mechanism 223, the second clamping mechanism 224 and the third clamping mechanism 225 may refer to a clamping structure in the conventional technology, and are not limited and described herein.
Specifically, the first gripper 223 is disposed between the tape inlet 201 and the tape outlet 202, and the first gripper 223 and the tape feed mechanism 21 are disposed in this order in the packing tape conveying direction. The second clamping mechanism 224, the cutting member 221, the welding member 222, and the third clamping mechanism 225 are sequentially disposed at a lower portion of the head body 2.
The packing belt firstly passes through the first clamping mechanism 223 and enters the belt feeding mechanism 21, the packing belt is driven by the belt feeding mechanism 21 to be output to the guide belt groove 11 and guided to enter the sealing mechanism 22, the packing belt sequentially passes through the second clamping mechanism 224, the cutting element 221, the welding element 222 and the third clamping mechanism 225 and is output to the external packing chute, the packing belt returns to the sealing mechanism 22 again after being guided to surround the goods through the packing chute, and for the specific transmission process of the packing belt, the packing belt conveying process of a conventional strapping machine can be referred to, and the detailed description is omitted.
And because the tape feeding mechanism 21 and the sealing mechanism 22 are integrated and mounted on the sliding seat 12 together, the tape feeding mechanism 21 and the sealing mechanism 22 can be conveniently detached by an operator. In addition, in the tightening process of the packing belt, the guide belt groove 11 is used as a bearing part to bear the tension of the packing belt, and further, the belt feeding mechanism 21 is prevented from being applied with tension. The guide belt groove 11 is not provided with a power component and a moving component, so that the guide belt groove 11 can be effectively prevented from being damaged due to overlarge tension, the condition that the belt feeding mechanism 21 directly bears the tension of a packing belt and is damaged is overcome, and the use reliability of the head of the bundling machine is improved.
More importantly, the tape feeding mechanism 21 generally comprises a feed roller 211, a pinch roller 212 and a second driving mechanism 213, wherein the pinch roller 212 is positioned above the feed roller 211, and the second driving mechanism 213 is provided with a driving motor to drive the feed roller 211 to rotate, so that the packing tape is output through the space between the feed roller 211 and the pinch roller 212. Because the tape feeding mechanism 21 does not bear the pulling force of the packing tape in the tensioning process, the tape feeding mechanism 21 is only used for conveying the packing tape, the diameter of the tape feeding wheel 211 adopted by the tape feeding mechanism 21 is smaller, and the size of the rotating shaft of the tape feeding wheel 211 is also designed to be smaller because the guide tape groove 11 replaces the tape feeding wheel 211 to serve as a main stress component when the packing tape is tensioned. For the second driving mechanism 213, the motor model of the configuration is also correspondingly smaller, which is more beneficial to reducing the manufacturing cost.
There are various forms for the representation entity of the first driving mechanism 13, for example: the first driving mechanism 13 is an electric pushing cylinder, and a push rod of the electric pushing cylinder is connected with the sliding seat 12; or, the first driving mechanism 13 includes a driving motor, a gear and a rack, the gear is rotatably disposed on the mounting base 1, the rack is slidably mounted on the mounting base 1, the gear is engaged with the rack, the driving motor is connected to the gear in a transmission manner, and the rack is connected to the sliding seat 12.
Further, the mounting base 1 is provided with a support member 14, and the guide belt groove 11 is provided on the support member 14.
Specifically, in the tensioning process of the packing belt, the tension of the packing belt on the guide belt groove 11 is large, so that the overall structural strength of the guide belt groove 11 is improved to improve the bearing capacity of the guide belt groove. A support member 14 is disposed inside the guide belt groove 11, and the support member 14 can effectively support the guide belt groove 11 inside the guide belt groove 11, so that the tensile force applied to the guide belt groove 11 during tightening of the strapping band is transmitted to the support member 14 to be effectively supported by the support member 14. The supporting part 14 is located between the guide belt groove 11 and the sliding seat 12, when in use, the packing belt exerts a pulling force on the guide belt groove towards the sliding seat 12, and the supporting part 14 between the two can effectively provide a supporting force for the guide belt groove 11.
Preferably, guide belt groove 11 includes a first sub-groove portion 111 and a second sub-groove portion 112, first sub-groove portion 111 has an arc-shaped structure, and second sub-groove portion 112 has a strip-shaped structure; the first sub-slot portion 111 is located above the second sub-slot portion 112, a lower port of the first sub-slot portion 111 communicates with the second sub-slot portion 112, the first sub-slot portion 111 is disposed on the top and side portions of the support member 14, and the second sub-slot portion 112 is disposed laterally below the support member 14.
Specifically, guide belt groove 11 includes a first sub-groove portion 111 and a second sub-groove portion 112 that are connected together. The first sub-groove portion 111 is integrally of an arc-shaped structure and is arranged on the support component 14, and the first sub-groove portion 111 is used for changing the conveying direction of the strapping tape on one hand, and the first sub-groove portion 111 is used for bearing the tensile force generated when the strapping tape is tensioned on the other hand. The second sub-groove 112 is mainly used for guiding and conveying the strapping band into the sealing mechanism 22. After entering the guide groove 11, the strapping band is first conveyed along the first sub-groove portion 111 and enters the second sub-groove portion 112, and then, the strapping band is discharged from the second sub-groove portion 112 and enters the sealing mechanism 22.
Preferably, the bottom of the mounting base is also provided with a return belt groove 16, and the return belt groove 16 is positioned below the second sub-groove portion. Specifically, in order to realize a function integration design, a return belt groove 16 is arranged at the bottom of the mounting base, and a packing belt output from the sealing mechanism 22 is guided by the return belt groove 16 after being wound around the goods for one circle and reenters the sealing mechanism 22 so as to meet the requirements of tensioning and welding. Wherein upon tightening the strapping band will be disengaged from the return strap channel 16 to be strapped to the cargo surface. The return belt groove 16 generally includes a fixing strip 161 and two fins 162, the fins are disposed on two sides of the fixing strip, a groove structure for the strapping tape to pass through is formed between the fixing strip 161 and the two fins 162, the fins 162 can move relative to the fixing strip 161 to open and close the two fins, so as to meet the requirement of the strapping tape to be separated when the strapping tape is tensioned, and the specific structural form of the return belt groove 16 can refer to the belt groove structure in the conventional art, which is not limited or described herein.
In order to satisfy the requirement of small volume and easy entry of the packing belt into the sealing mechanism 22 while the integrated design is achieved, the fixing strip is disposed below the supporting member, and the second sub-groove portion is formed between the fixing strip and the supporting member. In particular, said fixing strip is intended to cooperate with two fins 162 to form, on the one hand, return strap slot 16, and, on the other hand, with said supporting member to form said second sub-slot portion. In this way, the outlet of the second sub-groove portion is located at a short distance from the outlet of the return belt groove 16 to allow the strapping band to enter the sealing mechanism 22, and at the same time, the fixing strip is shared to form the second sub-groove portion 112 and the return belt groove 16, so that the overall structure is more compact.
In addition, for the first sub-groove portion, the guide belt groove includes an arc-shaped shielding member 110, the arc-shaped shielding member 110 is disposed outside the supporting member 14, and the first sub-groove portion 111 is formed between the arc-shaped shielding member 110 and the supporting member 14.
Furthermore, in order to ensure smooth sliding of the sliding seat 12 and at the same time ensure that the sliding seat 12 can stably and reliably carry the handpiece body 2. The other end of the mounting base 1 is provided with two parallel support rails 15, and both sides of the sliding seat 12 are respectively provided with guide grooves (not labeled), into which the support rails 15 are inserted at the corresponding sides.
Specifically, the mounting base 1 forms two support rails 15 for mounting the sliding seat 12, and the sliding seat 12 slides along the two support rails 15. Wherein, slide holder 12 includes a mounting frame 121 and two side sliding frames 122, and side sliding frames 122 are disposed at corresponding sides of mounting frame 121, and the guide groove is formed between side sliding frame 122 and mounting frame 121. The mounting frame 121 is used for carrying the head body 2, and a guide groove is formed between the side sliding frame 122 and the mounting frame 121 to fit the support rail 15. Since the sliding seat 12 is designed in a split manner, during assembly, the mounting frame 121 can be placed between the two support rails 15, and then the side sliding frame 122 is fixed on the mounting frame 121, so that the operator can assemble the sliding seat quickly. In order to ensure smooth sliding of the sliding seat 12, the side sliding frame 122 is provided with rollers 123 arranged up and down, the rollers 123 are located in the guide grooves, and the support rail 15 is located between the rollers 123 arranged up and down.
Still further, in order to ensure that the strapping band can smoothly enter the sealing mechanism 22, the mounting frame 121 is further provided with a guide sleeve (not labeled) disposed between an inlet of the strap threading channel 203 and an outlet of the guide strap slot 11.
Still further, the handpiece body 2 comprises a shell 23, the upper part of the shell 23 is provided with a tape inlet 201 and a tape outlet 202, and the bottom of the shell 23 forms a tape threading channel 203; the feed roller 211 and the pinch roller 212 are rotatably disposed in the housing 23 between the feed port 201 and the discharge port 202, and the cutting element 221 and the welding element 222 are located above the threading passage 203.
Specifically, the tape feeding mechanism 21 and the sealing mechanism 22 share the same housing 23 for the head body 2, so that the tape feeding mechanism 21 and the sealing mechanism 22 can be mounted on the same side, and the size reduction and integration can be realized.
The specific use process of the strapping machine is described with reference to the drawings.
In the tape threading process, the packing tape enters the casing 23 through the tape inlet 201 and passes through the first clamping mechanism 223 to enter between the tape feeding wheel 211 and the pressing wheel 212 of the tape feeding mechanism 21, the packing tape is output from the tape outlet 202 to enter the guide tape slot 11 under the driving action of the tape feeding wheel 211, then the packing tape enters the sealing mechanism 22 through the guide tape slot 11, and finally the packing tape is output from the sealing mechanism 22 to the external packing chute, is guided by the packing chute to surround the goods and then returns to the sealing mechanism 22 again.
After the both ends of the packing band are gripped by the first gripping mechanism 223 and the second gripping mechanism 224 during the tightening process, the first driving mechanism 13 drives the sliding seat 12 to move away from the guide band groove 11. Because the first clamping mechanism 223 and the second clamping mechanism 224 are both installed and fixed in the machine head body 2, under the driving action of the first driving mechanism 13, the first clamping mechanism 223 and the second clamping mechanism 224 move synchronously, the first clamping mechanism 223 and the second clamping mechanism 224 can pull the packing belt at the same time, the tensioning distances of two ends of the packing belt are the same, and the packing belt is guided by the guide belt groove 11, so that the first clamping mechanism 223 and the second clamping mechanism 224 can apply the same tension to two ends of the packing belt. Therefore, the two ends of the packing belt can be uniformly stressed, and the phenomenon that the packing quality is reduced due to the fact that the packing tightness degree of the two sides of the goods is different due to the fact that the two ends of the packing belt are unevenly stressed is avoided. Meanwhile, because the two ends of the packing belt are stressed in a balanced manner, the packing belt can be made of materials with common materials, so that the manufacturing cost of the packing belt is reduced, and the overall packing cost is reduced.
In addition, during the feeding process of the strapping band by the band feeding mechanism 21, the free end of the strapping band enters the sealing mechanism 22 first and is output and fed via the packaging chute, and finally is fed into the sealing mechanism 22 again, at this time, two layers of strapping bands are formed at the welding element 222 (the feeding process can refer to the strapping band feeding process of the strapping machine). After the tightening operation of the strapping band is completed by the first clamping mechanism 223 and the second clamping mechanism 224, the strapping band may be subjected to a cutting and welding process. At this time, the third gripping mechanism 225 grips the wrapping tape in place of the first gripping mechanism 223, and at the same time, the first gripping mechanism 223 releases the wrapping tape, and the wrapping tape fed out from the tape feeding mechanism 21 to the sealing mechanism 22 is cut by the cutting element 221. Then, the packing belt in which the front side of the third clamping mechanism 225 and the rear side of the second clamping mechanism 224 are stacked together is subjected to a welding process by the welding member 222, so that both end portions of the packing belt are welded together and bind the goods. Finally, the second and third clamping mechanisms 224, 225 release the strapping band to complete the strapping operation.
Based on the above technical solution, optionally, the installation positions of the guide belt groove 11 and the machine head body 2 can also be exchanged, that is, the machine head body 2 is fixedly installed on the installation base 1, and the guide belt groove 11 and its related accessory parts are installed on the sliding seat 12. Thus, in the actual use process, when the packing belt is tensioned, the sliding seat 12 drives the guide belt groove 11 to move, so as to tension the packing belt.
The mode of the transmission connection of the output power of the motor can be a mode of adding a speed reducer on a rotating shaft of the motor, and is not limited and described herein.
