According to the feeding and cutting device provided by the embodiment, the processes of feeding the material belt 800, cutting the material belt 800 and discharging the finished product are realized through the mutual matching of the cutting mechanism 1, the feeding mechanism 2 and the conveying mechanism 3, and compared with the manual mode in the prior art, the feeding and cutting device is continuous and uninterrupted in production, saves the production time and effectively improves the production efficiency; meanwhile, the material belt 800 is cut by arranging the cutting mechanism 1, so that compared with the mode of manually breaking off workpieces in the prior art, the deformation of the workpieces is reduced, and the qualification rate of finished products is improved; in addition, the conveying mechanism 3 can take out finished products and waste materials which are subjected to injection molding from the injection molding machine, manual fingers are not required to be in direct contact, the condition that the fingers are scalded is avoided, and the personal health and safety of operators are ensured.
The feeding and discharging device is compact in structure, the overall dimension length of the whole device is 1000mm, 800mm and 1700mm, the occupied area is small, and the production space and the production cost are saved.
As shown in fig. 1-2, the blanking mechanism 7 is mainly divided into two parts, one part for conveying finished parts and the other part for conveying waste materials. The blanking rotary driving source is specifically a rotary motor, the driving wheel and the driven wheel are used for tensioning the conveying belt 71 together, and the conveying belt 71 can convey finished parts under the driving of the rotary motor. Meanwhile, the other part includes a waste hopper 72 and a waste chute 73 communicating with the waste hopper 72 for transporting the waste.
As shown in fig. 3 to 4, the feeding mechanism 2 includes a pulling assembly 21 and a fall preventing assembly 22, wherein the pulling assembly 21 is used for pulling the material belt 800, and the fall preventing assembly 22 is used for preventing the material belt 800 from falling back. After the operator manually moves the material strip 800 forward to the position of the material pulling assembly 21, the material pulling assembly 21 can pull the material strip 800 to a position opposite to the cutting mechanism 1, so that the cutting mechanism 1 cuts the material strip 800.
As shown in fig. 4, the material pulling assembly 21 specifically includes a material pulling moving member 211 disposed on the base 5 and a material pulling lifting member 212 connected to the material pulling moving member 211, where the material pulling moving member 211 can drive the material pulling lifting assembly to move along the conveying direction of the material belt 800, and the material pulling lifting member 212 can move up and down along the vertical direction and selectively extend into the positioning hole of the material belt 800. Specifically, the material pulling moving component 211 includes a material pulling moving source 2111 disposed on the base 5 and a material pulling moving platform 2112 connected to an output end of the material pulling moving source 2111, where the material pulling moving source 2111 is specifically a material pulling moving cylinder, and the material pulling moving source 2111 can drive the material pulling moving platform 2112 to reciprocate along the conveying direction of the material belt 800.
Further, the pulling and lifting component 212 includes a pulling and lifting source 2121 disposed on the pulling and lifting platform 2112, and a pulling needle 2122 connected to an output end of the pulling and lifting source 2121, where the pulling needle 2122 is used to penetrate a positioning hole of the material strip 800, the pulling and lifting source 2121 is specifically a pulling and lifting cylinder, and the pulling and lifting source 2121 can drive the pulling needle 2122 to move vertically.
5-6, the pulling moving source 2111 drives the pulling moving platform 2112 and drives the pulling lifting assembly to move in a direction away from the cutting mechanism 1, as shown in FIG. 6, the direction is opposite to the forward moving direction of the material belt 800, that is, the direction is the backward direction of the material belt 800, the backward moving distance is matched with the number of the cutting mechanism 1 capable of cutting the formed workpieces each time, in this embodiment, the cutting mechanism 1 can cut two formed workpieces each time, and then the pulling moving platform 2112 and the pulling lifting assembly back the distance of the two workpieces under the action of the pulling moving source 2111; as shown in fig. 7, a pulling and lifting source 2121 drives a pulling needle 2122 to vertically move upwards so as to insert the pulling needle 2122 into a positioning hole of the material belt 800; as shown in fig. 8, in this state, the pulling movement source 2111 drives the pulling movement platform 2112 and drives the pulling lifting assembly to move the distance between the two workpieces in the direction approaching to the cutting mechanism 1, the direction is the same as the forward moving direction of the material belt 800, that is, the forward moving direction of the material belt 800, so that the material belt 800 to be cut is located at the position just opposite to the cutting mechanism 1; the pull-lift source 2121 then drives the pull needle 2122 vertically downward such that the pull needle 2122 is disengaged from the positioning hole of the tape 800, and the reset of the pull-lift source 2121 is completed, i.e., the initial state of the material assembly shown in fig. 6 is returned.
Because the operator manually moves the feeding section of the material belt 800 forward to the position of the material pulling component 21, the distance that the material belt 800 moves is manually pulled by the operator, and only by the experience of the operator, if the operator holds the material belt 800 untight when the material belt 800 is manually moved forward, the material belt 800 can be retracted, so that the fall-preventing component 22 needs to be arranged to prevent the material belt 800 from falling back, so that accurate alignment can be realized between the cutting mechanism 1 and the material belt 800, and the cutting precision is improved.
Further, as shown in fig. 9-10, the anti-falling component 22 includes an anti-falling seat 221, an anti-falling block 222 and a magnet 224, the cross section of the anti-falling block 222 is in a trapezoid structure, the anti-falling block 222 is rotatably arranged on the anti-falling seat 221 through a rotating shaft 225, and an anti-falling needle 223 for penetrating a positioning hole of the material belt 800 is arranged on the top surface of the anti-falling block 222.
As shown in fig. 9, the magnet 224 is disposed on the falling preventive seat 221 below the falling preventive block 222, and the magnet 224 is used to attract the falling preventive block 222 when the falling preventive block 222 is in an initial state, so that the falling preventive needle 223 is kept vertically downward. As shown in fig. 12, when the material belt 800 passes over the anti-falling needle 223, the material belt 800 pushes the anti-falling needle 223, the anti-falling block 222 overturns around the rotating shaft 225, and the material belt 800 presses the anti-falling needle 223 to avoid the material belt 800, so that the forward movement of the material belt 800 is not blocked. As shown in fig. 10, when the material belt 800 continues to move to the position of the material pulling assembly 21, the material pulling needle 2122 is inserted into the material belt 800 positioning hole to stop the material belt 800, at this time, the magnet 224 attracts the anti-falling block 222, and the anti-falling block 222 reversely turns, so that the anti-falling needle 223 is inserted into the material belt 800 positioning hole corresponding thereto. In order to ensure that the anti-falling needle 223 can prevent the material belt 800 from reversing backwards, two limiting shafts 226 are rotatably arranged on the anti-falling seat 221, and the two limiting shafts 226 are positioned on two sides of the rotating shaft 225 and used for limiting the anti-falling block 222.
The anti-falling component 22 is similar to a ratchet mechanism, can realize unidirectional and intermittent overturning movement, does not block the forward motion of the material belt 800, is convenient for the material belt 800 to pass smoothly, and more importantly, if the material belt 800 has a backward trend, the anti-falling needle 223 is inserted into the positioning hole of the material belt 800 to prevent the material belt 800 from backward reversing, so that the alignment accuracy and the cutting accuracy of the cutting mechanism 1 and the material belt 800 are improved, and the finished product qualification rate is improved.
Because the material strip 800 is cut by the cutting mechanism 1, the conveying mechanism 3 is required to convey the cut workpiece into the injection molding machine, and in order to enable the cutting mechanism 1 to realize blanking and effectively avoid the conveying mechanism 3, as shown in fig. 11, the cutting mechanism 1 specifically comprises a blanking component 11 and two blanking moving components 12 respectively arranged at two sides of the blanking component 11, and the blanking moving components 12 can drive the moving parts of the blanking component 11 to horizontally move. Further, the blanking moving assembly 12 includes a blanking moving source 121 and a blanking moving platform 122 connected to an output end of the blanking moving source 121, where the blanking moving source 121 is specifically a rodless cylinder, and the blanking moving source 121 can drive the blanking moving platform 122 to move horizontally.
The blanking assembly 11 includes a blanking lower die 111, a blanking driving source 112 disposed on a blanking moving platform 122, and a blanking upper die 113 connected to an output end of the blanking driving source 112, wherein the blanking upper die 113 is located above the blanking lower die 111, the blanking driving source 112 is specifically a blanking cylinder, and the blanking driving source 112 can drive the blanking upper die 113 to vertically move up and down relative to the blanking lower die 111. Wherein the lower blanking die 111 takes a lower die plate as a substrate, and a forming groove for blanking and forming a workpiece is formed in the lower die plate. In order to further improve the accuracy of blanking, a forming positioning column is arranged in the forming groove and is used for penetrating through a workpiece positioning hole of a workpiece, so that the guiding and positioning effects are achieved, and the deviation of the material belt 800 in the blanking process is prevented, so that the blanking accuracy is influenced.
In order to prevent the upper blanking die 113 from hard extrusion between the upper blanking die 113 and the lower blanking die 111 under the action of the blanking driving source 112, and facilitate the conveying mechanism 3 to pick up the workpiece after blanking, a return spring and a slider are further arranged in the forming groove, one end of the return spring is connected to the bottom wall of the forming groove, and the other end of the return spring is provided with a slider for bearing the workpiece.
After the material belt 800 moves onto the floating blocks in the forming groove under the drive of the material pulling assembly 21, the blanking moving source 121 drives the blanking moving platform 122, and drives the blanking driving source 112 and the blanking upper die 113 to move towards the direction close to the blanking upper die 113 until reaching the position where the blanking upper die 113 and the blanking lower die 111 are opposite; at this time, the punching driving source 112 can drive the punching upper die 113 to move vertically downward in a direction approaching the punching lower die 111, the punching upper die 113 pushes the slider to move downward, and compresses the return spring, and the material belt 800 is punched under the combined action of the punching upper die 113 and the forming groove of the punching lower die 111, so that the work pieces separated from each other are formed.
After the workpiece is blanked, the blanking driving source 112 can drive the blanking upper die 113 to vertically move upwards in a direction away from the blanking lower die 111, and the floating block pushes the blanked workpiece to vertically move downwards under the action of the compressed reset spring, so that the workpiece positioning hole is separated from the forming positioning column, and the subsequent conveying mechanism 3 is convenient to convey. Then, as shown in fig. 12, the blanking moving source 121 drives the blanking moving table 122, and drives the blanking driving source 112 and the blanking upper die 113 to move in a direction away from the blanking upper die 113. The upper blanking die 113 can be selectively opposite to the lower blanking die 111, so that not only can the blanking of a workpiece be realized, but also an effective avoiding space can be provided for the conveying mechanism 3.
The angle of the workpiece cut by the cutting mechanism 1 in the forming groove has an angle deviation from the angle required by the injection molding machine due to the limitation of the existing mechanism, so that the conveying mechanism 3 needs to have the functions of picking up the workpiece, conveying the workpiece and rotating the workpiece.
