Description

Technical Field

[0001] This utility model relates to the technical field of artificial leather production equipment, and in particular to a molding die for calendering artificial leather. Background Technology

[0002] Artificial leather is a type of imitation leather material made by laminating polyvinyl chloride (PVC), polyurethane (PU), or other polymer resins onto a woven or non-woven fabric base. It is widely used in footwear, apparel, bags, furniture, and automotive interiors. Calendering is one of the main processes in artificial leather production, characterized by high production efficiency, controllable costs, and suitability for large-scale continuous production.

[0003] The molding die for calendered artificial leather typically consists of components such as heated rollers, embossing rollers, rubber rollers, a transmission system, and a frame. During the production process, uniformly plasticized resin is calendered into sheets by multiple sets of rollers and bonded to the base fabric. Finally, the embossing rollers press the desired texture onto the leather surface. Traditional embossing rollers are usually fixed to the drive shaft by flanges or multiple sets of bolts. When changing rollers with different patterns, a large number of fasteners need to be disassembled, which is cumbersome and time-consuming, seriously affecting production efficiency and order response speed, and making it difficult to quickly adapt to the production needs of products with different thicknesses. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a molding die for calendering artificial leather, which solves the problems of cumbersome and time-consuming operation and poor flexibility when changing embossing rollers in traditional dies.

[0005] This utility model also provides a molding die for calendering artificial leather, including a frame. A fixed block is fixedly connected to the upper surface of the frame, and an adjusting block symmetrical to the fixed block is also fixedly connected to the upper surface of the frame. A movable block is slidably connected to the inner surface of the adjusting block. Two fixed plates are fixedly connected to the upper surface of the movable block, and fixing bolts are provided on the inner surfaces of the two fixed plates. A second driven shaft is movably connected to the inner surface of the movable block. An embossing roller is provided on the outer surface of the second driven shaft. A connecting block one is fixedly connected to one end of the second driven shaft. A first driven shaft is movably mounted on the fixed block, and a connecting block two is movably sleeved on the first driven shaft. The connecting block two is threadedly connected to the connecting block one. This realizes the quick installation, fixing, and disassembly of the embossing roller on the driven shaft. The threaded connection of the connecting block eliminates the traditional complex connection process, significantly shortens the operation time for changing rollers with different patterns, and greatly improves the mold's adaptability to different product patterns and production efficiency.

[0006] Preferably, the frame is provided with a roller groove, and a drive shaft is movably connected inside the roller groove. A rotary motor is fixedly connected to the side surface of the frame, and the output end of the rotary motor passes through the frame and is fixedly connected to the drive shaft. A drive roller is fixedly connected to the outer surface of the drive shaft. The rotary motor directly drives the drive shaft, providing a stable and reliable power source for the entire calendering process. This ensures a stable and adjustable linear speed between the drive roller and the embossing roller, providing a fundamental guarantee for continuous and uniform embossing.

[0007] Preferably, one end of the drive shaft is fixedly connected to a gear one, and one end of the first driven shaft is fixedly connected to a gear two, with gear one and gear two meshing together; the meshing of the gears achieves precise synchronous transmission from the drive shaft to the driven shaft, effectively preventing problems such as leather surface tearing, pattern distortion, or incomplete pressing that may occur due to asynchronous speeds between the embossing roller and the drive roller, thus ensuring the stability of the embossing quality.

[0008] Preferably, the frame is provided with a cooling channel, and the cooling channel is provided with a filter screen; the cooling channel can effectively and quickly cool the molded finished product; the internal filter screen can keep the cooling medium pure, prevent the flow channel from being blocked, ensure the long-term stable operation of the cooling system, and extend the service life of the mold.

[0009] Preferably, two sets of guide plates are symmetrically arranged on the upper surface of the frame; the two sets of symmetrical guide plates can regulate and guide the artificial leather base fabric or semi-finished product before entering the calendering area, effectively preventing deviation, wrinkling and other phenomena, and ensuring that the material enters the roller gap in a flat and centered state. This is a key structure to ensure that the final product has neat edges and centered patterns.

[0010] Preferably, a protective shell is fixedly connected to the side surface of the frame; the protective shell can isolate moving parts such as gears and drive shafts from the external environment, play a safety protection role in preventing dust and foreign objects from being drawn in, and can also effectively prevent operators from accidentally coming into contact with moving parts.

[0011] Beneficial effects: The molding die for calendered artificial leather in this technical solution, through modular connecting blocks and locking structures, enables the rapid assembly, disassembly, and replacement of embossing rollers, greatly shortening the mold change time and effectively improving production efficiency and the equipment's adaptability to different patterned products.

[0014] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0015] Reference Figure 1-5 This utility model provides a molding die for calendering artificial leather, which includes a frame 1, which is the supporting structure for the entire die. A fixing block 3 and an adjusting block 2 are fixedly connected to the upper surface of the frame 1. The adjusting block 2 has a slide rail or groove inside, so that the movable block 17 can slide horizontally within it. Two fixing plates 15 are welded to the upper surface of the movable block 17. After the fixing bolts 16 pass through the threaded holes on the fixing plates 15, they can press against the adjusting block 2, thereby locking the movable block 17 in the desired position.

[0016] The embossing section includes a drive shaft 11, a first driven shaft 10, and a second driven shaft 21. The drive shaft 11 is movably connected to the roller groove 14 of the frame 1 via a bearing. A drive roller 13 is fixed on the outer surface of the drive shaft 11. The drive roller 13 and the embossing roller 12 cooperate to form a calendering gap. One end of the drive shaft 11 is fixedly connected to the output shaft of a rotating motor 18 fixed on the side of the frame 1 via a coupling. The second driven shaft 21 is movably connected to the movable block 17, and the embossing roller 12 is sleeved on its outer surface.

[0017] The quick-change mechanism is the core of this utility model. First, loosen the fixing bolts 16 on the fixing plate 15 to make the movable block 17 movable. Since one end of the second driven shaft 21 passes through the interior of the movable block 17 and forms a movable connection with it, the movable block 17 can be slidably separated from the second driven shaft 21. A connecting block 1 20 is fixedly connected to one end of the second driven shaft 21. The inner hole of the connecting block 2 19 is provided with an internal thread, which can be connected with the external thread of the connecting block 1 20. When it is necessary to disassemble the embossing roller 12, loosen the connecting block 2 19 and move it on the first driven shaft 10 and push it away from the connecting block 1 20 to separate the first driven shaft 10 from the second driven shaft 21, thus realizing the quick disassembly of the embossing roller 12. During installation, align the second driven shaft 21 with the first driven shaft 10, push the connecting block 2 19 close to the connecting block 1 20, and tighten the connecting block 2 19 to make the first driven shaft 10 and the second driven shaft 21 securely connected.

[0018] In addition, the frame 1 has a cooling channel 6 cast inside, which is used to circulate cooling water to cool the finished product. The filter screen 7 in the channel can prevent impurities from clogging the flow channel. Two sets of guide plates 4 are symmetrically installed on the upper surface of the frame 1 by bolts, which are used to guide the base fabric to enter the calendering area smoothly. The protective shell 5 on the side of the frame 1 can enclose gear 9 and gear 8, which can play a safety protection role.

[0019] Working principle: Start the rotating motor 18 to drive the drive shaft 11 and drive roller 13 to rotate. The gear 9 at one end of the drive shaft 11 drives the gear 8 that meshes with it to rotate, thereby driving the first driven shaft 10, the second driven shaft 21 and the embossing roller 12 to rotate in opposite directions synchronously. Under the guidance of the guide plate 4, the artificial leather base fabric is fed into the calendering gap between the drive roller 13 and the embossing roller 12. Under the action of high temperature and pressure, the pattern on the surface of the embossing roller 12 is clearly imprinted on the leather surface.

[0020] When it is necessary to replace the embossing roller 12 with a different pattern, first loosen the fixing bolt 16, slide the movable block 17 outward, then loosen the connecting block 2 19 to separate it from the connecting block 1 20, so that the old embossing roller 12 can be removed, and the new embossing roller 12 can be reinstalled into the mold. Tighten the connecting block 2 19 and the connecting block 1 20 to secure them together, and the replacement of the embossing roller 12 can be completed. Push the movable block 17 back to its original position and tighten the fixing bolt 16 to complete the entire mold replacement process.

[0021] During operation, the circulating cooling water in the cooling channel 6 can quickly cool down the molded artificial leather; the protective shell 5 can effectively prevent foreign objects from entering the gear transmission area and ensure operational safety.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
