The embodiments of the present disclosure may be performed independently of each other, or may be performed together in a mutually dependent relationship.

[0036] Reference Figures 1 to 11 The utility model discloses a sponge board punching die system, including a punching machine 100, and also includes a transfer mechanism 200, a feeding conveying mechanism 300, and a positioning conveying mechanism 400. The plates are sequentially fed and separated by the transfer mechanism 200, transported by the feeding conveying mechanism 300, and unloaded by the positioning conveying mechanism 400, and then transported to a predetermined position on the punching and cutting table in the punching machine 100 and punched into small pieces of products by the punching machine 100. The transfer mechanism 200 includes a frame 1 and a transfer driving mechanism arranged on the frame 1 and a transfer translation plate 2 driven by the transfer driving mechanism. The transfer translation plate 2 is provided with a transfer frame that is driven and lifted by a transfer lifting unit. The transfer frame is provided with a plurality of driving units 5. The driving unit is provided with a clamping member and a needle fixed by the clamping member. Among the above, the driving unit 5 is preferably an ordinary The cylinder is provided, and the driving units 5 are arranged in pairs as a group of fixed units, and the driving units 5 are preferably arranged at a forty-five degree tilt, so that each group of fixed units has two needles 6, and the needles 6 are also arranged at forty-five degrees to the vertical direction. This not only ensures that the needles 6 can move a shorter distance to insert into the plate to a certain depth, but also the relative arrangement of the needles 6 can prevent the plate from escaping from the front and rear directions. The direction of plate movement is forward, and the opposite direction of plate movement is backward. The positioning and conveying mechanism 400 includes a positioning blocking mechanism, two conveying needle plates, a needle plate moving mechanism that drives the two conveying needle plates to move, and an opening and closing mechanism that causes the two conveying needle plates to move relative to or oppositely. The plate can be fixed by clamping the conveying needle plates and conveyed to a predetermined position on the punching table in the punching machine 100 by the needle plate moving mechanism.

[0037] The working principle of the above structure is as follows: the worker first uses a forklift to fork the stack of plates 600 into the rack, and then the transfer drive mechanism drives the transfer translation plate 2 to move above the plate stack 600, and the transfer lifting unit drives the transfer frame to descend to the grabbing position, and the drive unit 5 drives the needle to extend and pierce the top plate in the plate stack 600, and the transfer drive mechanism drives the transfer translation plate 2, the transfer lifting unit, the transfer frame and the plate to move to the feed conveying mechanism 300 and the drive unit 5 drives the needle to retract, and then the transfer lifting unit and the transfer drive mechanism work in sequence to drive the transfer frame to rise and the transfer translation plate 2 to return to the top of the plate stack 600 to start the next grabbing cycle. The structure makes full use of the characteristic design of the plate, which is not only simple in structure but also highly efficient. When the plate is conveyed to the position close to the positioning conveying mechanism 400 through the feeding conveying mechanism 300, the positioning blocking mechanism blocks the plate for positioning, and then the opening and closing mechanism drives the conveying needle plate to move relatively so that the conveying needle on the conveying needle plate penetrates into the plate, and then the conveying needle plate is driven to a predetermined position on the punching table in the punching machine 100 by the needle plate moving mechanism. The punching table punches the plate into small pieces of products. The punched products can be collected manually or by equipment. The above structure realizes the loading, dividing, transferring, unloading and cutting processes of the plate, which not only greatly improves the production efficiency but also saves the production cost.

[0038] like Figure 2 As shown, the feed conveying mechanism 300 uses a belt drive to convey the plates, and its structure is designed according to the prior art, so it will not be described in detail.

[0039] like Figure 6 As shown, the clamping member includes a connecting seat 7 and a splint 8. The splint 8 is provided with a positioning groove (not shown in the figure). The positioning groove is a semicircular groove, and the needle 6 is a circular needle. The needle 6 is placed in the positioning groove for positioning, and then the connecting seat 7 and the splint 8 are locked together by screws to tightly clamp the needle 6. The connecting seat 7 is an L-shaped plate, one end of the connecting seat 7 is connected to the drive unit 5, and the other end is locked with the splint 8. The above result facilitates assembly and later replacement of the needle 6.

[0040] like Figures 2 to 5As shown, the transfer drive mechanism includes a transfer motor 9, a transfer guide rail 10, two transfer driving pulleys, two transfer driven pulleys, and a transfer belt 11 arranged on the transfer driving pulley and the transfer driven pulley. The transfer frame 3 is fixed to the transfer belt 11. The specific fixing method is to use a locking plate to lock the transfer belt 11 between the end plate and the locking plate of the transfer frame 3 by screws, so that the transfer is moved by the transfer belt 11, and the transfer frame 3 is slidably matched with the transfer guide rail 10, and the transfer The conveying guide rail 10 is fixed to the frame 1 by iron blocks at both ends of the sliding shaft, and the transfer frame 3 is provided with a sliding hole that cooperates with the transfer guide rail 10. The two transfer driving pulleys are connected by the transfer main shaft, and the two transfer driven pulleys are connected by the transfer slave shaft. The transfer main shaft and the transfer slave shaft are both arranged on the frame 1 through bearing seats. The transfer motor 9 is connected to the transfer main shaft. Through the above structure, we can realize the forward and backward movement of the transfer frame 3, thereby dragging the plate pierced by the needle 6 to the feed conveying mechanism 300.

[0041] like Figure 4 As shown, it also includes a transfer roller 12, a transfer drive unit 13 and a transfer rack 14 arranged on the frame 1. Transfer gears 15 are provided at both ends of the transfer roller 12, and a transfer connecting plate is provided on the transfer drive unit 13. The ends of the transfer roller 12 are connected to the transfer connecting plate through bearings and the transfer gear 15 is engaged with the transfer rack 14. The transfer roller 12 is pushed to move to the bottom of the plate to be rotated. Because the plate has a certain weight and the friction between the plates is relatively large, the resistance is large when dragging the plate. Therefore, when the needle 6 penetrates the plate, the transfer lifting unit 4 will drive the needle 6 to rise, thereby lifting the front end of the plate to a certain height. At this time, the transfer drive unit 13 will drive the transfer roller 12 to move to the bottom of the plate, lift and support the rear end of the plate, and then the needle 6 drives the plate to move, so that movement is easier. The transfer drive unit 13 is preferably a cylinder.

[0042] like Figure 4As shown, it also includes a lifting mechanism set on the frame 1 and a lifting seat 16 lifted by the lifting mechanism, the lifting mechanism includes a lifting motor 20 and a sprocket lifting structure, the sprocket lifting structure includes a plurality of lifting upper sprockets 17, a plurality of lifting lower sprockets 18, and a lifting chain 19 set on the lifting upper sprocket 17 and the corresponding lifting lower sprocket 18. The lifting upper sprocket 17 is mounted on the frame 1 through a bearing, and the lifting lower sprocket 18 is mounted on the lifting seat 16 through a bearing. The stacked plates are located on the lifting seat 16. When the uppermost plate is transferred away In order to keep the height of the top plate consistent, the lifting mechanism will drive the lifting seat 16 to rise a certain distance, so as to facilitate the transfer of the top plate. In the above, the corresponding upper lifting sprockets 17 and the corresponding lower lifting sprockets 18 are connected through a sprocket shaft, and the lifting motor 20 drives the corresponding sprocket shaft to rotate through the belt transmission mechanism, thereby realizing the lifting of the lifting seat 16. The belt transmission mechanism, the upper lifting sprocket 17, the lower lifting sprocket 18, and the sprocket shaft in the above structure are all manufactured by existing technology, so the specific installation and connection structure are not described in detail.

[0043] like Figure 7 As shown, the lifting seat 16 is provided with a plurality of roller moving mechanisms, and the roller moving mechanisms include a moving motor 21, a plurality of moving rollers and a plurality of moving belts 22. Moving pulleys are provided at both ends of the moving roller 25 and the moving motor 21, and the two ends of the moving roller 25 are arranged on the lifting seat 16 through bearings. The moving pulleys are connected by the corresponding moving belts 22 so that the moving motor 21 can drive all the moving rollers 25 to rotate. In the above structure, the moving motor 21 can drive all the moving rollers 25 to rotate by connecting the corresponding moving pulleys in series through a plurality of moving belts 22. Through the above structure, the stacking rollers on the lifting seat 16 can be made The stacked plates are moved so that they can be moved to a predetermined position. In the above structure, the moving motor 21, the moving pulley, the moving roller 25 and the moving belt 22 are all components of the prior art. Therefore, the structure of the moving roller 25 and the moving belt 22 and the series structure are not described in detail. The roller moving mechanism of the present application has two groups and is arranged opposite to each other. A passive roller mechanism is also provided between the two groups of roller moving mechanisms. The passive roller mechanism also includes a plurality of moving rollers 25. The moving rollers 25 are also installed on the lifting seat 16 through bearings, but the passive roller mechanism has no power. The above structure is set to leave space between the passive roller mechanism and the roller moving mechanism to facilitate the insertion of the fork of the forklift. As a further structure, the two roller moving mechanisms of the present application share a motor, and the two roller moving mechanisms are connected by a common shaft 23. As a further structure, an extension frame 24 is also included. The extension frame 24 is provided with two roller moving mechanisms and a passive roller mechanism located between them. The above structure is the same as the structure on the lifting seat 16, and is also used to provide power to the stacked plates so that they can be moved to the lifting seat 16.

[0044] As shown in the figure, guide plates 26 are provided on the lifting seat 16. The two guide plates 26 are arranged opposite to each other and are trumpet-shaped, so as to prevent the stacked plates from deviating from the predetermined position when moving.

[0045] As shown in the figure, the positioning blocking mechanism includes a positioning bracket 27 and a positioning baffle 28. The positioning bracket 27 is provided with a positioning cylinder 29 and a positioning slide 30. The positioning baffle 28 is connected to the positioning cylinder 29 and rises and falls, and the positioning slide 30 slides with the positioning slide hole of the positioning baffle 28. When the plate is transported to the position close to the positioning conveying mechanism 400 through the feeding conveying mechanism 300, the positioning cylinder 29 drives the positioning baffle 28 to rise, so that the plate waits for subsequent transportation at a predetermined position.

[0046] like Figure 8 As shown, the opening and closing mechanism includes an opening and closing reduction motor 31, a belt transmission structure, and an opening and closing connecting plate 32. One end of the opening and closing connecting plate 32 is set on the opening and closing frame through a guide rail assembly 33, and the other end of the opening and closing connecting plate 32 is connected to the corresponding conveying needle plate 34. When the plate is blocked and positioned by the positioning blocking mechanism, the end of the plate is just located between the conveying needles 35 of the conveying needle plate 34. At this time, the opening and closing reduction motor 31 drives the opening and closing connecting plate 32 to move along the guide rail assembly 33 through the belt transmission structure, and the movement of the opening and closing connecting plate 32 drives the conveying needle plate 34 to move relatively, so that the conveying needle 35 penetrates the two sides of the end of the plate. Specifically, the belt transmission structure includes a belt transmission wheel 35, three short transmission shafts 36, a transmission belt 37, and an opening and closing belt 38. A double-headed transmission shaft is provided on the opening and closing reduction motor 31. The short The end of the transmission shaft 36 and the two ends of the double-headed transmission shaft are respectively fixed to the corresponding belt drive pulleys 35, and the transmission belt 37 and the opening and closing belt 38 are respectively connected to the corresponding belt drive pulleys 35, and the opening and closing connecting plate 32 is fixed to the opening and closing belt 38 so as to move under the drive of the opening and closing belt 38. Through the above structure, an opening and closing reduction motor 31 can drive the transmission belt 37 and an opening and closing belt 38 to move through the double-headed transmission shaft and the corresponding belt drive pulley 35, and the transmission belt 37 drives the other opening and closing belt 38 to move through the short transmission shaft 36 and the corresponding belt drive pulley 35. The two opening and closing belts 38 are arranged in parallel, so that the opening and closing belt 38 drives the opening and closing connecting plate 32 to move relative to or toward each other. The three short transmission shafts 36 mentioned above are all installed on the opening and closing frame through bearing seats, and the opening and closing reduction motor 31 is also installed on the opening and closing frame.

[0047] like Figures 9 to 11As shown, the needle plate moving mechanism includes a moving motor 39, a gear transmission structure, a relatively arranged moving rack 40, and two opening and closing frames 41 arranged on the moving rack 40. The moving rack 40 is arranged on the punch 100 through the guide rail assembly 33, and the conveying needle plate 34 is connected to the opening and closing mechanism. Through the above structure, the moving motor 39 can drive the moving rack 40 to move along the guide rail assembly 33 through the gear transmission structure, thereby driving the conveying needle plate 34 and the plate to move to the punching position of the punch 100 through the opening and closing frame 41. The specific structure is: the gear transmission structure It includes a gear transmission shaft 42 connected to a moving motor 39, two gear shafts 43, and transmission gears 44 arranged at both ends of the gear shaft 43, and a driving gear 45 arranged at both ends of the gear transmission shaft 42.

The driving gear 45 is engaged with the corresponding transmission gear 44, and the moving rack 40 is engaged with the corresponding transmission gear 44. Therefore, by driving a moving motor 39, the movement of two parallel moving racks 40 can be realized, thereby realizing the movement of the two opening and closing frames 41.

[0048] like Figure 1 As shown. As a preferred structure of the present application, a finished product conveyor 500 is further provided at the discharge port of the punch press 100. The finished product conveyor 500 also uses a belt drive to convey the finished products. Its structure is a prior art design and is not described in detail.
