[0020] In the present application, unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or integrated; it can be directly connected or indirectly connected through an intermediate medium.

[0021] The embodiments of the present application provide a fully automatic winding and cutting device. As Figure 1 , 2 shown, the fully automatic winding and cutting device 100 includes: a material storage mechanism 1, a slitting mechanism 2, a winding mechanism 3, a cutting mechanism 4, an upper shaft mechanism 5 and an unwinding mechanism 6. The winding mechanism 3 is arranged downstream of the material storage mechanism 1 and winds the products output by the material storage mechanism 1; the cutting mechanism 4 is arranged on the winding mechanism 3 and cuts the products when the winding mechanism 3 is full of rolls to facilitate the winding mechanism 3 to change rolls; the upper shaft mechanism 5 is used to supply a new air shaft to the winding mechanism 3 to change the full roll winding shaft; the unwinding mechanism 6 is used to transfer the full roll winding shaft of the winding mechanism 3 outside the fully automatic winding and cutting device 100 for centralized stacking and transportation.

[0022] The material storage mechanism 1 includes a cooling component 11 and a material storage component 12 arranged in sequence from front to back. The material storage component 12 is arranged on a support frame 13. The cooling component 11 includes a plurality of cooling rollers 111 and a pressing roller 112 arranged in sequence from front to back. The plurality of cooling rollers 111 can rotate around their own axis, and cooling water is passed through each cooling roller 111 to cool and shape the product passing around the plurality of cooling rollers 111. A pressing roller 112 is configured to be able to approach and move away from the last cooling roller 111. The pressing roller 112 is used to press the product against the surface of the last cooling roller 111 to facilitate the conveying of the product. The material storage component 12 includes a plurality of material storage rollers 121 arranged in sequence from front to back. The plurality of material storage rollers 121 are arranged alternately up and down from front to back. When the product is in the material storage component 12, it bypasses the upper side of the upper material storage roller 121 and the lower side of the lower material storage roller 121. At least a pair of the lower material storage rollers 121 are rotatably arranged on a lifting plate 122. The lifting plate 122 is slidably connected to the support frame 13 to drive this pair of material storage rollers 121 to move in the up and down direction. When the material storage component 12 stores materials, the lifting plate 122 drives this pair of material storage rollers 121 to move downward to increase the moving path of the product in the material storage component 12, achieving the purpose of temporarily storing the product. The lifting plate 122 drives this pair of material storage rollers 121 to move upward to reduce the moving path of the product in the material storage component 12 to release the temporarily stored product.

[0023] As Figure 3 shown, the slitting mechanism 2 includes a plurality of slitting knives 21. The plurality of slitting knives 21 are arranged in sequence in the left-right direction, and each slitting knife 21 can move in the left-right direction to be able to adjust the width of the product to be slit; the slitting knife 21 is a hob and / or a utility knife. The hob is suitable for cutting EVA products, and the utility knife is suitable for cutting PVC products. The slitting mechanism 2 of the present application can replace the slitting knife 21 according to the material of the product, so that the full-automatic winding and cutting device 100 can meet the winding of different products and expand the production range.

[0024] As Figure 1 、 2 shown, the winding mechanism 3 includes a frame 31, a driving roller 32 rotatably arranged on the frame 31 around its own axis, a servo motor 33 drivingly connected to the driving roller 32, a support guide rail 34 extending in the front-rear direction, a winding shaft 35 rotatably and movably supported on the support guide rail 34, and a tightening device 36 clamped at both ends of the winding shaft 35.

[0025] The frame 31 is arranged on the rear side of the slitting mechanism 2 so as to be movable in the front-to-back direction and swingable in the left-to-right direction through a moving mechanism 7. The moving mechanism 7 includes a base frame 71 capable of moving in the front-to-back direction and a swinging assembly 72 drivingly connected between the base frame 71 and the frame 31. The swinging assembly 72 is used to drive the frame 31 to move back and forth in the left-to-right direction relative to the base frame 71 to reduce the cracking of the product during the winding process and improve the winding quality. A plurality of moving wheels 711 are arranged at the bottom of the base frame 71, and the base frame 71 drives the frame 31 and the mechanism carried on the frame 31 to move in the front-to-back direction through the moving wheels 711.

In the embodiment of the present application, the traction motor is a servo motor, which is used to flexibly adjust the linear speed of the upper traction roller 371 to ensure constant tension for conveying products. The lower traction roller 372 can be both rotatable around its own axis and movable in the up and down directions on the frame 31. The upper pressure cylinder 373 is used to drive the lower traction roller 372 to approach the upper traction roller 371 to press the product against the upper traction roller 371.

[0027] The active roller 32 extends in the left-right direction, and the servo motor 33 is used to drive the active roller 32 to rotate around its own axis. The servo motor 33 flexibly adjusts the rotation speed of the active roller 32 to ensure that the product is conveyed with constant tension to avoid the product being pulled and wrinkled.

[0028] The support guide rail 34 is fixedly arranged on the frame 31 and extends backward from the rear end of the active roller 32. The support guide rail 34 is used to support the winding shaft 35 and the air expansion shaft 38 used to exchange the winding shaft 35 on the rear side of the active roller 32. The specifications of the air expansion shaft 38 are consistent with those of the winding shaft 35. The air expansion shaft 38 is used to supplement the rear of the active roller 32 after the winding shaft 35 is fully rolled. When the product on the winding shaft 35 is disconnected from the product conveyed by the active roller 32, the air expansion shaft 38 replaces the winding shaft 35 for the winding operation.

[0029] like Figure 2 , 4As shown, the tightening device 36 includes a pair of movable frames 361 arranged opposite to each other on the left and right, a pair of tightening cylinders 362 arranged opposite to each other on the left and right, and a winding motor 363. The pair of movable frames 361 can be movably arranged on the outer side of the frame 31 in the front-to-back direction. A tightening cylinder 362 is arranged on the top of a movable frame 361. Each tightening cylinder 362 is used to connect with the end of the winding shaft 35. A connecting hole 310 for the tightening member of the tightening cylinder 362 to extend into the frame 31 is provided. The tightening members of the pair of tightening cylinders 362 tighten the two ends of the winding shaft 35 toward the middle, and the connecting hole 310 extends in the front-to-back direction so that the tightening device 36 drives the winding shaft 35 to move in the front-to-back direction; the winding motor 363 is arranged on a tightening cylinder 362 and is transmission-connected to the tightening cylinder 362 to drive the winding shaft 35 connected to the pair of tightening cylinders 362 to rotate around its own axis.

[0030] A first translation assembly 364 and a mobile driving assembly 365 are provided between the mobile frame 361 and the frame 31. The first translation assembly 364 includes a first push-pull cylinder 3641, a first translation rail 3642 extending in the front-rear direction, and a first translation block 3643 slidingly matched with the first translation rail 3642. The first translation rail 3642 is installed on the frame 31, and the first translation block 3643 is installed on the mobile frame 361.

The mobile drive assembly 365 includes a rack 3651 extending in the front-to-back direction, a gear (not shown in the figure) meshing with the rack 3651, and a magnetic powder driver (not shown in the figure) connected to the gear transmission. The rack 3651 is installed on the frame 31, and the gear is rotatably arranged on the mobile frame 361. The magnetic powder driver is used to drive the gear to rotate around its own axis. The relative movement of the gear and the rack 3651 enables the mobile frame 361 to move back and forth along the rack 3651 relative to the frame 31. The first translation assembly 364 is used to quickly drag the mobile frame 361 to move in the front-to-back direction when the winding shaft is changed, so as to position the winding shaft 35 as soon as possible. The magnetic powder driver of the mobile drive assembly 365 is used to adjust the distance between the winding shaft 35 and the active roller 32 when the winding shaft 35 is winding up and winding up.

[0032] Since the diameters of the air-expanding shafts for winding EVA products and PVC products are different, in order to enable the fully automatic winding and cutting equipment 100 of the present application to meet the winding needs of EVA products and PVC products, the second swing plate 412 can move relative to the first swing plate 411 through the waist groove adjustment plate 413 to adjust the distance between the loaded cutting knife 42 and the supplemented air-expanding shaft, so that the cutting mechanism 4 can be suitable for air-expanding shafts of different specifications; the cutting knife 42 that can adjust the distance between it and the air-expanding shaft ensures that the starting point of the product left after cutting meets the starting point requirements of air-expanding shafts of different diameters, effectively reducing the waste film of rolling.

[0033] The pressure roller 43 is arranged at the end of the second swing plate 412 away from the first swing plate 411. When the cutting knife 42 moves between the supplementary air inflation shaft 38 and the fully rolled winding shaft 35, the product between the supplementary air inflation shaft 38 and the fully rolled winding shaft 35 is tightened to facilitate cutting by the cutting knife 42.

The first lifting assembly 54 includes a first lifting cylinder 541, a first lifting rail 542 extending in the up-down direction, and a first lifting block 543 slidably engaged with the first lifting rail 542.

The clamping assembly 52 is arranged on the frame 31 so as to be movable both in the up-down direction and in the front-back direction through the first lifting assembly 54 and the second translation assembly 53.

The air rods of the pair of clamping cylinders 522 are simultaneously ejected, and can tightly hold the end of the air shaft 38 located in the notch 520, so that the air shaft 38 can be moved in the up-down direction and in the front-back direction. For example, the air shaft 38 can be moved from the rear end of the support guide rail 34 to between the driving roller 32 and the winding shaft 35 for rewinding; and the upper shaft mechanism 5 can press the air shaft 38 against the driving roller 32, and when the driving roller 32 rotates, the air shaft 38 performs friction winding.

A handle 611 is arranged at the bottom of the coil unloading table 61 for the operator to slowly pull the coil unloading table 61 and the lifted take-up reel 35 backward along the third translation rail 632 to move the full coil take-up reel 35 out of the fully automatic winding and cutting equipment, so as to facilitate the subsequent packing and transportation of the full coil take-up reel 35.

[0038] As shown Figure 1As shown, the product of the present application sequentially bypasses the cooling assembly 11, the material storage assembly 12, the slitting mechanism 2, the traction device 37, and the driving roller 32 and is then wound on the winding shaft 35. The winding shaft 35 rotates under the drive of the winding motor 363 for winding. As the thickness of the winding on the winding shaft 35 gradually increases, the magnetic powder driver drives the moving frame 361 to drive the winding shaft 35 to gradually move backward; when the sheet material is fully wound on the winding shaft 35, the first push-pull cylinder 3641 pushes the winding shaft 35 away from the driving roller 32, and the driving roller 32 stops rotating. The lifting plate 122 of the material storage assembly 12 moves downward to store the product conveyed to the winding mechanism 3. The operator places the air shaft 38 with an empty shaft on the support guide rail 34. The upper shaft support 51 moves above the air shaft 38, and the clamping bottom plate 521 moves downward to place the end of the air shaft 38 into the notch 520. The clamping cylinder 522 clamps both ends of the air shaft 38. The upper shaft mechanism 5 moves the air shaft 38 to the rear of the driving roller 32, and the pressing block 523 presses downward to press the end of the air shaft 38 on the support guide rail 34. The cutting mechanism 4 swings upward so that the cutting knife 42 cuts the product between the air shaft 38 and the winding shaft 35. After cutting, the cutting mechanism 4 resets, the pressing block 523 moves upward, and the upper shaft mechanism 5 presses the air shaft 38 on the driving roller 32. The driving roller 32 rotates under the drive of the servo motor 33. The material storage assembly 12 releases the stored product and normally conveys the product backward. The friction between the air shaft 38 and the driving roller 32 causes the air shaft 38 to rotate to frictionally wind the starting end of the product; at the same time, the winding motor 363 stops rotating after driving the fully wound winding shaft 35 to rotate to finish winding the cut product. The tightening device 36 releases the winding shaft 35 so that the winding shaft 35 is supported on the support guide rail 34; the tightening device 36 moves forward under the pull of the first push-pull cylinder 3641 to align with the air shaft, the tightening cylinder 362 tightens the air shaft 38, the upper shaft mechanism 5 releases the air shaft 38 and moves backward to wait for the next roll change. The magnetic powder driver drives the air shaft 38 to move backward to leave the driving roller 32 and actively winds under the drive of the winding motor 363; the unwinding table 61 moves upward to lift the fully wound winding shaft 35 on the support guide rail 34. The operator pulls the unwinding table 61 backward and unloads the fully wound winding shaft 35, and the unwinding table 61 resets.

[0039] The structure of the present application is simple, which can realize automatic slitting, automatic winding, automatic roll change, and automatic winding, reduce the waste film at the start of winding, save time and effort, and improve production efficiency; and it can wind two kinds of products, EVA and PVC, with multiple functions in one machine, expand the scope of application, and reduce costs.
