[0002] The long baffles are welded on both sides of the conveyor belt. The baffles are perpendicular to the surface of the conveyor belt and are used to block the goods and prevent them from deviating from the conveyor belt during transportation. The conveyor belt is wound around the roller, and the part of the conveyor belt that is transmitted to the roller will bend with the roller. In order to make the baffle bend smoothly around the roller with the conveyor belt, it is necessary to open holes and cut out the baffle at a small interval to reduce the bending radius so that the baffle can bend smoothly.

[0027] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0028] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0029] A baffle punching and cutting machine, such as Figures 1 to 10 As shown, it includes a platform 1 and a punching and cutting assembly 2, a positioning assembly and a pulling assembly installed on the platform 1. The pulling assembly pulls the long strip baffle 5 to move step by step. When the baffle 5 moves one step and pauses, the punching and cutting assembly 2 moves from top to bottom to impact the baffle 5. After one impact, a through hole and a cut are processed on the baffle 5. The positioning assembly is used to position and limit the baffle 5 so that the baffle 5 can move stably along the set direction.

[0030] In this embodiment, the workpiece is a baffle 5, which is in the shape of a long strip, and its cross section is in the shape of an L or T. Figure 2 As shown. In other words, the baffle 5 is composed of two long strip-shaped plate structures connected vertically to each other, one of which needs to be punched and cut, and the plate-shaped structure is set as the processing part 51, and the other plate-shaped structure is set as the auxiliary part 52. After the punching is completed, the auxiliary part 52 of the baffle 5 is welded to the conveyor belt, the length direction of the baffle 5 is consistent with the length direction of the conveyor belt, and a baffle 5 is connected to each end of the conveyor belt in the width direction. The processing part 51 is perpendicular to the surface of the conveyor belt, which can prevent the objects on the conveyor belt from sliding off.

[0031] The punching and cutting component 2 is as follows Figures 3 to 5 As shown, it includes a bracket 21, a cylinder 22, a punching and cutting die 23, a die holder 24, a first guide assembly, a material discharge baffle 26, a material receiving box 27 and a pad 28. The bracket 21 is mounted on the platform 1, the cylinder 22 is mounted on the bracket 21, the drive shaft of the cylinder 22 extends downward, the drive shaft of the cylinder 22 is connected to the die holder 24, and the punching and cutting die 23 is mounted on the die holder 24. The cylinder 22 is connected to and drives the die holder 24 to rise or fall. The first guide assembly is used to guide the die holder 24, so that the lifting and lowering movement of the die holder 24 and the punching and cutting die 23 is smoother, and the punching and cutting die 23 is prevented from being skewed and offset. Specifically, the first guide assembly includes a slider 251 and a guide rail 252. The guide rail 252 is fixedly arranged on the bracket 21. The length direction of the guide rail 252 is parallel to the length direction of the driving shaft of the cylinder 22. One end of the slider 251 is slidably arranged on the guide rail 252, and the other end is fixedly connected to the die holder bracket 24.

[0032] Punching cutter die 23 as Figure 6 and 7As shown, it includes a knife seat 231 and a cutting knife 232 and an opening portion 233 installed on the knife seat 231. The knife seat 231 is installed on the knife die support 24, and the cutting knife 232 and the opening portion 233 are fixedly arranged at the bottom of the knife seat 231. Specifically, a plurality of bolt holes 234 are provided on the knife seat 231, and the knife seat 231 is connected to the knife die support 24 above it by bolts passing through the bolt holes 234. The cutting knife 232 and the opening portion 233 protrude from the bottom surface of the knife seat 231, and the tops of the cutting knife 232 and the opening portion 233 are connected to the bottom of the knife seat 231, and the bottom blade of the cutting knife 232 is flush with the bottom of the opening portion 233. A first discharge hole 2311 is provided on the knife seat 231, and the first discharge hole 2311 is a through hole on the knife seat 231, and the first discharge hole 2311 is close to one end of the knife seat 231. The opening portion 23 is used to punch holes in the baffle plate 5 to form an opening on the baffle plate 5. The opening portion 23 is cylindrical, in other words, a through hole is provided on the opening portion 23, which is a cut-out hole 2331, and the cut-out hole 2331 is connected to the first discharge hole 2311. The cutting blade 232 and the opening portion 233 are connected to form a T-shape.

[0033] The pad 28 is arranged on the platform 1, just below the punching and cutting die 23. The baffle 5 passes between the pad 28 and the punching and cutting die 23. When the punching and cutting die 23 impacts the baffle 5, the pad 28 plays a role in supporting the impacted part of the baffle 5. When the blade of the cutting knife 232 cuts onto the pad 28, the punching and cutting die 23 can completely punch open the baffle 5 and form a through hole and an incision. The punching and cutting die 23 is covered with a high-elastic sponge 29, i.e., a pad knife foam. The sponge 29 covers the blade of the cutting knife 232 and the bottom surface of the knife seat 231, and does not block the cutting hole 2331. When the punching cutter die 23 cuts downward into the baffle 5, the sponge 29 directly contacts the baffle 5 and is squeezed, and when the punching cutter die 23 rises and returns, the sponge 29 rebounds and squeezes the baffle 5 off the punching cutter die 23, preventing the baffle 5 from being lifted by the punching cutter die 23 due to friction. In this embodiment, the material of the pad 28 is nylon.

[0034] Based on the above structure, the punching principle and working process of the punching cutter die 23 are as follows: the processing portion 51 is located below the punching cutter die 23. When punching, the cutting knife 232 and the opening portion 233 contact the processing portion 51 almost at the same time. The opening portion 23 impacts the processing portion 51 and cuts off the material in contact with the opening portion 23. The cut-off material is set as discharge material. The discharge material enters the cutting hole 2331. A processing hole 511 is formed on the processing portion 51 as a through hole with the same cross-sectional shape as the cutting hole 2331. Figure 2As shown. The cutting knife 232 makes an incision on the processing part 51, and cuts out a slit as the processing slit 512. One end of the processing slit 512 is connected to the processing hole 511 in the middle of the processing hole 511, and the other end extends to the end of the processing part 51 away from the auxiliary part 52. The cutting knife 232 and the opening part 233 are generally made of metal, and the baffle 5 is generally made of polymer materials or composite materials such as PU and TPU. The discharge will stay in the cutting hole 2331 due to the friction between it and the opening part 23. When the opening part 23 makes the next impact, the new discharge also enters the cutting hole 2331, pushing the discharge formed by the last impact upward, that is, the discharge in the cutting hole 2331 gradually moves upward, and finally will be pushed out of the first discharge hole 2311. Similarly, if the sponge 29 is not provided, when the punching cutter die 23 resets and rises, the baffle 5 may be lifted by the punching cutter die 23 due to friction, affecting the normal operation of the baffle 5. After the sponge 29 is arranged, the punching function of the punching cutter die 23 is not affected. At the same time, after the punching cutter die 23 rises, the sponge 29 rebounds and pushes the baffle plate 5 down to separate it from the punching cutter die 23.

[0035] In order to allow the material ejected from the first discharge hole 2311 to be discharged smoothly into the designated position without affecting the normal operation of the punching and cutting machine, the die holder 24 above the punching and cutting die 23 cannot close the outlet of the first discharge hole 2311, and a discharge baffle 26 and a receiving box 27 are provided. Specifically, the shape of the die holder 24 is flexibly set, such as Figure 8 As shown, the die cutter support 24 includes a first portion 241 directly connected to the knife seat 231 and a second portion 242 directly connected to the cylinder 22, and the second portion 242 is connected to the upper end of the first portion 241. The discharge baffle 26 is located above the knife seat 231, and between the knife seat 231 and the second portion 242. The discharge baffle 26 is U-shaped, which is equivalent to three side walls of a rectangular parallelepiped connected in sequence. The second portion 242 is connected to the top of the discharge baffle 26, which is equivalent to covering the top surface of the rectangular parallelepiped. The knife seat 231 is connected to the bottom of the discharge baffle 26, which is equivalent to covering the bottom surface of the rectangular parallelepiped, and the outlet of the first discharge hole 2311 is located on the bottom surface. From the top, only one side wall of the rectangular parallelepiped is open, which is set as an opening, and the discharge from the first discharge hole 2311 can only be discharged from the opening. The material receiving box 27 connects to the opening and receives the discharge discharged from the opening.

[0036] In this embodiment, the cross-sectional shape of the opening portion 23 is a waist-shaped hole.

[0037] The positioning assembly includes a second guide assembly 31 and a clamping assembly 32. The second guide assembly 31 is used to guide the baffle 5 to run on the punching and cutting machine. The second guide assembly 31 is provided with at least two groups. In this embodiment, the second guide assembly 31 is provided with two groups. The two groups of second guide assemblies 31 are respectively arranged on both sides of the punching and cutting assembly 2, and one group is located at the edge of the platform 1 and the entrance of the baffle 5 into the platform 1, mainly used to straighten the baffle 5 so that the baffle 5 enters the punching and cutting assembly 2 straightly. Figure 3 As shown at A in the figure. The clamping assembly 32 guides the baffle plate 5 when it is running and fixes the baffle plate 5 so that it does not slide when punching. The clamping assembly 32 is located between the two sets of second guide assemblies 31. Specifically, the clamping assembly 32 is located at the entrance of the baffle plate 5 into the punching cutout assembly 2, as shown in FIG. Figure 3 Another set of second guide components 31 is located at the outlet of the baffle 5 out of the punching cutout component 2, as shown in FIG. Figure 3 As shown at C in the figure, after the baffle 5 enters the platform 1, it passes through the second guide assembly 31 at A, the pressing assembly 32 at B and the second guide assembly 31 at C in sequence.

[0038] The second guide assembly 31 is as follows Fig. 9 As shown, it includes a first positioning member 311, a first roller 312 and a first connecting member 313, and the first positioning member 311 and the first roller 312 are connected by the first connecting member 313. The first positioning member 311 and the platform 1 are relatively fixed, and the first positioning member 311 is a U-shaped structure. In other words, the first positioning member 311 includes two vertical rods arranged in parallel and spaced apart and a cross bar between the two vertical rods, and the two ends of the cross bar are respectively connected to the two vertical rods. The space between the two vertical rods is a first positioning groove 314, and the end of the first positioning groove 314 away from the cross bar is set as the inlet and outlet of the first positioning groove 314. The first roller 312 is a cylindrical structure, and the first roller 312 is rotatably mounted on the first connecting member 313. The inlet and outlet of the first positioning groove 314 are oriented toward the first roller 312 and are spaced apart from the first roller 312, and the central axis of the first roller 312 is parallel to or located in the plane where the U-shaped first positioning member 311 is located, that is, there is a gap between the first positioning member 311 and the first roller 312, and the first positioning groove 314 is connected to the gap and forms a passage for the baffle 5. Specifically, when the baffle 5 passes through the second guide assembly 31, the processing portion 51 passes through the first positioning groove 314, and the auxiliary portion 52 passes through the gap between the first positioning member 311 and the first roller 312.

[0039] Furthermore, the first connecting member 313 is connected to the first positioning member 311 in an adjustable position, so that the interval between the first positioning member 311 and the first roller 312 can be finely adjusted, and the interval is adjusted to the point where the baffle 5 can pass through the second guide assembly 31 without shaking. Specifically, the first connecting member 313 is a plate-like structure, and a long strip through hole is provided on the first connecting member 313. The first connecting member 313 and the first positioning member 311 are connected by at least one bolt passing through the long strip through hole. After passing through the long strip through hole, the bolt enters the first positioning member 311 and presses the first connecting member 313 onto the first positioning member 311. In this way, the position of the bolt on the long strip through hole on the first connecting member 313 can be changed, thereby changing the interval between the first positioning member 311 and the first roller 312.

[0040] In this embodiment, the second guide assembly 31 at C is further connected to a backing wheel 315, and the backing wheel 315 and the first roller 312 are respectively located on both sides of the width direction of the baffle 5. In other words, the backing wheel 315 can contact an end of the processing part 51 away from the auxiliary part 52, and the first roller 312 contacts the auxiliary part 52. Further, the position of the backing wheel 315 is adjustable to adapt to processing parts 51 of different heights. The backing wheel 315 can be installed in a variety of ways, such as, the backing wheel 315 is rotatably installed on a connecting rod, one end of the connecting rod is connected to the backing wheel 315, and the other end is positionally adjustable on the first positioning member 311, the connecting rod structure is the same as the structure of the first connecting member 313, and the connection method of the connecting rod and the first positioning member 311 is also the same as the connection method of the first connecting member 313 and the first positioning member 311. By rotating the connecting rod relative to the first positioning member 311 and changing the angle between the two, the distance between the backing wheel 315 and the first roller 312 can be adjusted.

[0041] The clamping assembly 32 is as follows Fig.10As shown, it includes a second positioning member 321, a second roller 322, a second connecting member 323 and a pressing cylinder 324. The structure of the second roller 322 is the same as that of the first roller 312, and the structure of the second positioning member 321 is the same as that of the first positioning member 311. The second positioning member 321 is fixed relative to the platform 1, and a second positioning groove 325 is provided on the second positioning member 321 for the processing part 51 to pass through. The second positioning member 321 and the pressing cylinder 324 are respectively connected to the two ends of the second connecting member 323. The second roller 322 is located between the second positioning member 321 and the pressing cylinder 324, and the pressing cylinder 324 is connected to and drives the second roller 322 to move, so that the interval between the second positioning member 321 and the second roller 322 is increased or decreased, and the interval is for the auxiliary part 52 to pass through. In this way, when the baffle 5 is running, the clamping cylinder 324 drives the second roller 322 to move, increases the interval between the second positioning member 321 and the second roller 322, and allows the baffle 5 to pass through the clamping assembly 32 smoothly; when the baffle 5 stops, the clamping cylinder 324 drives the second roller 322 to move, reduces the interval between the second positioning member 321 and the second roller 322, and the second roller 322 presses the baffle 5 on the second positioning member 321, fixing the baffle 5 so that it does not slide during punching.

[0042] Furthermore, a photoelectric sensor is also installed at the clamping assembly 32 to determine whether there is material. When the end of the baffle 5 passes through the clamping assembly 32, the light path is no longer blocked by the baffle 5, and it is determined that the baffle 5 to be processed has been completed, and the punching and cutting machine automatically stops. Figure 3 As shown in G in .

[0043] The traction component is as follows Figure 3 As shown, it includes a linear module 41, a servo motor 42, a clamping cylinder 43, a slide rail 44 and a position sensor. The linear module 41 is installed on the platform 1, and the servo motor 42 is connected to and drives the linear module 41. The clamping cylinder 43 is installed on the linear module 41, and the linear module 41 drives the clamping cylinder 43 to move linearly back and forth. Specifically, the clamping cylinder 43 is connected to the nut block of the linear module 41, and the nut block is screwed on the screw rod of the linear module 41, and the screw rod is rotatably installed on the linear module 41. The servo motor 42 is connected to and drives the screw rod to rotate, and when rotating, it drives the nut block to move along the length direction of the screw rod. The linear module 41 can adopt the products and structures of the existing technology. The clamping cylinder 43 adopts the pneumatic clamping products and structures in the existing technology. The clamping claws of the clamping claw cylinder 43 can clamp and release the target product. Furthermore, in order to improve the stability of the linear movement of the clamping cylinder 43, a slide rail 44 is provided, one end of the clamping cylinder 43 is mounted on the nut block of the linear module 41, and the other end is slidably arranged on the slide rail 44. The linear movement direction of the clamping cylinder 43 is parallel to the movement direction of the baffle 5.

[0044] In this embodiment, the position sensor is a photoelectric sensor.

[0045] The position sensor is used to limit the position of the clamping cylinder 43 on the platform 1 and find the origin position. In this embodiment, three position sensors are provided, which are respectively used to limit the two end positions of the moving range of the clamping cylinder 43 on the platform 1 and the set origin position. The limitation of the two end positions is to ensure that the clamping cylinder 43 moves within the screw rod range of the linear module 41 to prevent the clamping cylinder 43 from being separated from the screw rod and becoming ineffective. The position sensors of the two end positions are respectively as follows: Figure 3 The origin position is located between the two end point positions and is the starting point for the movement of the clamping cylinder 43 set artificially. The position sensor at the origin position is as shown in FIG. Figure 3 As shown in F in the figure. Specifically, the clamping claw cylinder 43 is at the origin position, and the clamping claw at the front end thereof clamps the baffle 5 coming out of the second guide assembly 31 at C, and pulls the baffle 5 out at a set length and speed through the linear module 41. When the clamping claw cylinder 43 moves a set distance from the origin position, the clamping claw cylinder 43 automatically releases the baffle 5 and returns to the origin position, and the traction is performed in this way.

[0046] The punching and cutting machine can be connected to a control system to realize automatic operation of the punching and cutting machine. Specifically, the control system includes a controller and a control panel. The control panel, cylinder 22, servo motor 42, clamping cylinder 43, clamping cylinder 324, and various photoelectric sensors are electrically connected to the controller.

[0047] Based on the above structure, the working principle and process of the utility model are as follows: the worker puts one end of the baffle 5 through the second guide assembly 31 at A, the clamping assembly 32 and the second guide assembly 31 at C in sequence and then places it at the opening of the clamping jaw of the clamping jaw cylinder 43. Specifically, the processing part 51 passes through the first positioning groove 314 and the second positioning groove 325, and the first roller 312 and the second roller 322 contact the auxiliary part 52. Then adjust the backing wheel 315 so that the backing wheel 315 contacts the end of the processing part 51 away from the auxiliary part 52 to ensure that the baffle 5 does not shake. After installing the baffle 5, set the spacing between the processing holes 511 on the baffle 5 on the control panel, and then press the start button, and the punching and cutting machine will run automatically. Specifically, the traction assembly drives the baffle 5 to move one step according to the set distance, then stops and returns. At this time, the baffle 5 stops running, and the pressing cylinder 324 of the pressing assembly 32 drives the second roller 322 to press the baffle 5 on the second positioning member 321. Then, the cylinder 22 drives the punching cutter die 23 to descend and impact the processing part 51 and then rise, and the processing hole 511 and the processing seam 512 are formed on the processing part 51. Then, the pressing cylinder 324 drives the second roller 322 to release the baffle 5, and the clamping cylinder 43 clamps the processing part 51 and continues to move forward one step. The above process is repeated until the baffle 5 is processed.
