Description
Technical Field
[0001] This utility model belongs to the field of leather production technology. Specifically, it relates to an online roll-up packaging production line for the production of calendered PVC artificial leather, coated PU / PVC synthetic leather / artificial leather, calendered PVC flooring, coated PVC sports flooring, etc. Background Technology
[0002] Compared to natural leather, synthetic leather is artificially manufactured leather, produced through two main methods: calendering and coating. Calendering primarily uses PVC resin as its raw material. A PVC film produced by a four-roll calendering line is laminated with a base fabric. After winding, it is processed on a plasticizing and embossing production line using a guide chain and needle plate as a carrier. After winding, it is treated and wound by a surface treatment machine, resulting in PVC synthetic leather. Coating is divided into wet and dry methods. The wet method primarily uses PU resin as its raw material, using a base fabric as a carrier. The base fabric is impregnated with PU slurry on both sides, and after extrusion, washing, and plasticizing, it is wound by a winding machine, resulting in PU synthetic leather. The dry method primarily uses PU and PVC resin as its raw materials, using release paper as a carrier. A layer of PU resin is coated onto the release paper and plasticized, followed by a PVC layer. After plasticizing, it is laminated with the base fabric. After drying, the product is peeled off from the release paper, wound separately, unwound, and then treated and wound by a surface treatment machine, resulting in dry synthetic leather. This process is carried out using six precision... Taking a PVC sports flooring production line as an example, consisting of a 6T coating machine, six plasticizing ovens (6H), six coolers, and an electrical control system, the production line operates as follows: Online, a dual-station, dual-power center winding machine rolls materials with a diameter ≤1500mm. The materials are then manually cut, manually wound, and transferred to an appearance quality inspection facility. The length of the rolled material is 15M or 20M; materials shorter than 15M or 20M are considered waste. Commercial rolls with diameters of 280mm or 410mm, each weighing 80-100kg, require six operators and involve heavy manual labor. Therefore, an online winding and packaging production line that is easy to operate, has low labor intensity, high efficiency, and reduces resource waste is needed. Utility Model Content
[0003] The purpose of this utility model is to provide an online roll-up packaging production line that is easy to operate, has low labor intensity, high work efficiency, and reduces resource waste.

[0006] The dual-station single-power winding machine includes a winding frame, on which a winding power source, a first winding roller, and a second winding roller are installed. The winding power source is driven to the first winding roller and the second winding roller. A left pass roller and a right pass roller are respectively installed on the left and right sides of the winding frame. The product is sent out from the plasticizing oven and passes through the embossing machine, the cooling machine, and the transmission roller assembly in sequence before rotating into the storage machine. From the storage machine, it is sent out and passes through the first cutting mechanism, the right pass roller, the left pass roller, the second cutting mechanism, the product winding machine, the packaging platform, and the operating platform in sequence, realizing the online winding and packaging production of the product.
[0007] The embossing machine includes an embossing frame, a guide roller on the top of the embossing frame, and an embossing assembly on the embossing frame. The embossing assembly is located below the guide roller and includes a rotary motor, a rotary base, a rotary shaft, a rotary arm, a first embossing roller, and a second embossing roller. The rotary shaft is arranged in the front-to-back direction and is rotatably mounted on the rotary base via bearings. The rotary arm is arranged in the left-to-right direction and is connected to one end of the rotary shaft via a key. The rotary motor is driven and connected to the rotary shaft. The first embossing roller is located at the right end of the rotary arm, and the second embossing roller is located at the left end of the rotary arm.
[0008] The cooling machine includes several cooling rollers, and a first drive roller is provided on the product entry side of the cooling machine.
[0009] The drive roller assembly includes a first drive roller mounted on a first mounting frame column, a second drive roller and a drive pressure roller mounted on a second mounting frame column, and a third drive roller mounted on a third mounting frame column. The first drive roller is mounted on a column to the right of the cooler, and the drive pressure roller is mounted on a column to the right of the second drive roller.
[0010] A second drive roller is installed at the right inlet of the storage machine.
[0011] The first and second cutting mechanisms have the same structure, both including a cutting frame, a first lifting cylinder, a movable seat, a pressure roller, a fixed roller, a front-to-back translation cylinder, a mounting seat, a second lifting cylinder, a rodless cylinder, and a cutting blade. The fixed roller is rotatably mounted on the cutting frame in the front-to-back direction. The first lifting cylinder is mounted on the cutting frame and located above the fixed roller. The movable seat is mounted on the first lifting cylinder. The pressure roller is mounted on the movable seat in the front-to-back direction. The front-to-back translation cylinder is located on the left side of the cutting frame. The mounting seat is mounted on the front-to-back translation cylinder. The second lifting cylinder is mounted on the mounting seat. The rodless cylinder is mounted on the piston rod of the second lifting cylinder. The cutting blade is mounted on the rodless cylinder.
[0012] The first cutting mechanism has a third and a fourth transmission roller on the left side of the cutting frame; the second cutting mechanism has a fifth transmission roller on the right side of the cutting frame; and a sixth transmission roller is located on the cutting frame of the second cutting mechanism, to the left of the cutting blade of the second cutting mechanism.

[0014] The dual-station single-power winding machine of this application includes a winding frame, on which a winding power source, a first winding roller, and a second winding roller are installed. The winding power source is driven to the first winding roller and the second winding roller. A left pass roller and a right pass roller are respectively installed on the left and right sides of the winding frame. During normal winding, the product is sent out from the plasticizing oven and passes through the embossing machine, the cooling machine, and the transmission roller assembly in sequence before rotating into the storage machine. From the storage machine, it is sent out and passes through the first cutting mechanism, the right pass roller, the left pass roller, the second cutting mechanism, the product winding machine, the packaging platform, and the operating platform in sequence, realizing the online winding and packaging production of the product. When the winding length is ≤1500mm, the product is directly wound by the first winding roller or the second winding roller after passing through the right pass roller, and is cut by the first cutting mechanism, avoiding waste when the product length is less than 1500mm or 2000mm.
[0015] The embossing machine of this application includes a first embossing roller and a second embossing roller. By setting different patterns on the first embossing roller and the second embossing roller, the embossing requirements of different products can be met. Traditional embossing machines only have one embossing roller. When different patterns are required, the machine must be stopped and another embossing roller must be replaced. However, this application only needs to drive the rotating arm to rotate by a rotary motor to realize the conversion between the first embossing roller and the second embossing roller, thereby realizing different embossing requirements and improving the production efficiency of products.
[0016] In summary, this application has a simple structure and is convenient and quick to operate. By feeding the product out of the plasticizing oven and passing it sequentially through the embossing machine, cooling machine and transmission roller assembly before rotating it into the storage machine, and then feeding it out of the storage machine and passing it sequentially through the first cutting mechanism, right passing roller, left passing roller, second cutting mechanism, product winding machine, packaging platform and operating platform, the online winding and packaging production of the product is realized, which greatly improves the production efficiency of leather products.

The rodless cylinder 38 is mounted on the piston rod of the second lifting cylinder 37. The cutting blade 39 is mounted on the rodless cylinder 38.
[0026] The cooling machine 49 includes several cooling rollers 40, and a first drive roller 41 is provided on the inlet side of the product 48. A second drive roller 42 is provided at the right inlet of the storage machine 4. A third drive roller 43 and a fourth drive roller 44 are provided on the left side of the cutting frame 30 of the first cutting mechanism 5; a fifth drive roller 45 is provided on the right side of the cutting frame 30 of the second cutting mechanism 7, and a sixth drive roller 46 is provided on the cutting frame 30 of the second cutting mechanism 7, located to the left of the cutting blade 39 of the second cutting mechanism 7. A seventh drive roller 47 is provided on the right side wall of the plasticizing oven 1. The first drive roller 41, the second drive roller 42, the third drive roller 43, the fourth drive roller 44, the fifth drive roller 45, the sixth drive roller 46, and the seventh drive roller 47 can ensure the normal transport of the product 48.
[0027] In practical use, after the product 48 is plasticized in the plasticizing oven 1, it passes through the seventh transmission roller 47 located on the right side wall of the plasticizing oven 1 and the guide roller 20 located on the top of the embossing frame 19 to reach the embossing assembly. The first embossing roller 24 and the second embossing roller 25 of the embossing assembly are provided with patterns of different depths. The corresponding pattern is selected for embossing. If the pattern needs to be adjusted, the rotating shaft 22 can be driven by a rotary motor to drive the rotation of the rotating arm 23. This allows the product 48 to be embossed by the first embossing roller 24 and then by the second embossing roller 25. This conversion process does not require stopping the production line. After embossing by the second embossing roller 25, the product 48 enters the cooling machine 49 via the first drive roller 41 located on the product entry side and is cooled sequentially by several cooling rollers 40. After cooling, the product 48 sequentially passes through the first drive roller 26, the second drive roller 27, the drive pressure roller 28, the third drive roller 29, and the second drive roller 42 located at the right entry point of the storage machine 4, and enters the storage machine 4. Then, the product 48 is sent out from the left side of the storage machine 4 via the fixed roller 34 of the first cutting mechanism 5, the third drive roller 43, and the fourth drive roller 44 to the right pass roller 18 on the dual-station single-power winding machine 6. If the required winding length of the product 48 is... When the thickness is ≤1500mm, the product 48 passes through the right pass roller 18 and is then wound up by the first take-up roller 15 or the second take-up roller 16, and cut by the first cutting mechanism 5. During cutting, the first lifting cylinder 31 drives the pressure roller 33 downwards to cooperate with the fixed roller 34 to press the product 48. Then, the second lifting cylinder 37 and the rodless cylinder 38 cooperate to drive the cutting blade 39 downwards to cut the product 48. Finally, the forward and backward translation cylinder 35 drives the mounting base 36 to move back and forth, thereby driving the cutting blade 39 to move back and forth to completely cut the product 48. If it is necessary to wind up the product roll, the first cutting mechanism 5 does not work, and the product 48 passes through the right pass roller 18. After passing through the left pass roller 17 and the fifth drive roller 45, the product enters the second cutting mechanism 7, and then passes through the sixth drive roller 46 to reach the product winding machine 8 (the product winding machine 8 is a commercially available product, and its specific structure will not be described in detail). The product winding machine 8 winds up the product roll, and after winding, the second cutting mechanism 7 is used to cut it. The cutting process of the second cutting mechanism 7 is the same as that of the first cutting mechanism 5, and will not be described in detail. After winding, the product roll is packaged on the packaging platform 9 (the packaging platform 9 is a commercially available product, and its specific structure will not be described in detail). The operating platform 10 is used for hoisting (the operating platform 10 is a commercially available product, and its specific structure will not be described in detail), thus completing the online winding and packaging production of the product 48.
[0028] The dual-station single-power winding machine 6 of this application includes a winding frame 14, on which a winding power source, a first winding roller 15, and a second winding roller 16 are mounted. The winding power source is driven to drive the first winding roller 15 and the second winding roller 16. A left pass roller 17 and a right pass roller 18 are respectively mounted on the left and right sides of the winding frame 14. During normal winding, the product 48 is sent out from the plasticizing oven 1, passes through the embossing machine 2, the cooling machine 49, and the transmission roller assembly 3 in sequence, and then rotates into the storage machine 4. The product 48 is fed out and passes through the first cutting mechanism 5, the right passing roller 18, the left passing roller 17, the second cutting mechanism 7, the product winding machine 8, the packaging platform 9, and the operating platform 10 in sequence, realizing the online winding and packaging production of the product 48. When the winding length is ≤1500mm, the product 48 is directly wound by the first winding roller 15 or the second winding roller 16 after passing through the right passing roller 18, and is cut by the first cutting mechanism 5, avoiding waste when the length of the product 48 is less than 1500mm or 2000mm.
[0029] The embossing machine 2 of this application includes a first embossing roller 24 and a second embossing roller 25. By setting different patterns on the first embossing roller 24 and the second embossing roller 25, the embossing requirements of different products 48 can be met. The traditional embossing machine 2 has only one embossing roller. When different patterns are required, the machine must be stopped and another embossing roller must be replaced. However, this application only needs to drive the rotating arm 23 to rotate by a rotary motor to realize the conversion between the first embossing roller 24 and the second embossing roller 25, thereby realizing different embossing requirements and improving the production efficiency of products 48.
[0030] This application features a simple structure and convenient and quick operation. By feeding the product 48 out of the plasticizing oven 1, passing through the embossing machine 2, the cooling machine 49, and the transmission roller assembly 3 in sequence, it rotates back into the storage machine 4. From the storage machine 4, it is fed out and passes through the first cutting mechanism 5, the right passing roller 18, the left passing roller 17, the second cutting mechanism 7, the product winding machine 8, the packaging platform 9, and the operating platform 10 in sequence, realizing the online winding and packaging production of the product 48, which greatly improves the production efficiency of leather products 48.
