Description

Technical Field

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

[0002] Artificial leather is a plastic product that resembles leather in appearance and feel and can be used as a substitute. It is usually made by coating a fabric base with synthetic resin and various plastic additives. In my country, people usually refer to artificial leather made from PVC resin as PVC artificial leather. In the production process of artificial leather, the coated artificial leather needs to be calendered and stretched into a certain thickness and surface shape by a calender to facilitate further processing of the artificial leather.

[0003] The calender uses the cooperation of internal upper and lower pressure rollers to calender artificial leather. The artificial leather is conveyed between the pressure rollers and squeezed into shape. However, there is no limiting mechanism to stop the artificial leather during the conveying process, which will cause the artificial leather to deviate in direction and make it impossible to roll it completely, affecting the production of artificial leather. In addition, the pressure rollers cannot be cleaned in time, which will generate dust and affect production. Therefore, a composite calendering device for artificial leather production is proposed to solve the above problems. Utility Model Content

Multiple pressure rollers 2 are rotatably connected inside the support 1. The artificial leather is squeezed by the multiple upper and lower pressure rollers 2. An adjustment knob 5 is installed on the top of the support 1. The adjustment knob 5 can adjust the distance between the upper and lower pressure rollers 2 to produce artificial leather of different thicknesses. This is prior art and will not be described in detail here. A foot pad 6 is fixedly connected to the bottom of the support 1 to increase the contact area with the ground and protect the ground. A driving component 3 is installed on one side of the support 1 to drive the pressure rollers 2 to rotate and drive the calendering device to work. A limiting mechanism is installed inside the support 1 to limit the position of the artificial leather. The limiting mechanism includes a driving component and a moving component. A cleaning component is installed inside the support 1 to clean the dust on the surface of the pressure rollers 2.

[0035] The moving component includes a slide rod 17, which is fixedly connected inside the bracket 1 to limit the movement range of the moving component. A groove 16 is provided inside the bracket 1, and the slide rod 17 is located within the groove 16, allowing the moving component to slide within it. Two moving rods 8 are slidably connected to the center of the groove 16, and the two moving rods 8 are located inside the groove 16, limiting their movement range. The driving component includes a motor 4, which is mounted on one side of the bracket 1 to drive the limiting mechanism. A bidirectional screw 14 is rotatably connected inside the bracket 1, driving the moving rods 8 to adjust their spacing. One end of the bidirectional screw 14 is fixedly connected to the output end of the motor 4, driving the motor 4 to drive the bidirectional screw 14. The moving rods 8 are threadedly connected to the outside of the bidirectional screw 14. The bidirectional screw 14 drives the moving rod 8 to move. The moving rod 8 has a sliding hole 18 inside. The sliding rod 17 is located inside the sliding hole 18 and restricts the movement direction of the moving rod 8. The top of both moving rods 8 is fixedly connected to the limit block 7 to restrict the movement of the artificial leather. The limit block 7 is located on one side of the pressure roller 2. The artificial leather passes through the limit block 7 and then enters the pressure roller 2. The inner side of the limit block 7 is fixedly connected to the support strip 19. The outer side of the support strip 19 is rotatably connected to the support roller 20 to support the artificial leather and reduce friction. The artificial leather is fixed by the limiting mechanism, which can prevent the artificial leather from changing its position due to movement, thus avoiding the production of defective products. The motor 4 drives the bidirectional screw 14 to rotate and adjust the spacing of the limit block 7 to adapt to different sizes of artificial leather.

[0036] Reference Figure 2 , Figure 5 and Figure 6The cleaning assembly includes two fixed rods 15, which fix the cleaning assembly. Each fixed rod 15 has a groove 21 inside. A crossbar 22 is slidably connected between the two fixed rods 15, sliding within the groove 21. A scraper 23 is fixedly connected to one side of the crossbar 22, located on one side of the pressure roller 2. The scraper 23 cleans dust from the surface of the pressure roller 2. A fixed plate 12 is slidably connected to one side of the bracket 1, and the crossbar 22 is fixedly connected to one side of the fixed plate 12. The crossbar 22 is moved using the fixed plate 12 to adjust its position. A pin assembly is installed on the top of the fixed plate 12. A pin hole 11 is opened on one side of the bracket 1, and the pin of the pin assembly fixes the cleaning assembly within the pin hole 11. The pin assembly includes a fixing block 13, which fixes... The internal components are installed on the top of the fixed plate 12. The fixed block 13 has a housing 25 fixedly connected inside to protect the internal elastic structure. The housing 25 has a pin 26 slidably connected inside. The fixed plate 12 is fixed with the pin 26. A baffle 24 and a compression spring 10 are fixedly connected in the middle of the pin 26. A spring 10 is sleeved on the outside of the pin 26 to restrict the movement of the pin 26. A pull ring 9 is fixedly connected to one end of the pin 26. Pulling the pull ring 9 can move the pin 26. A cleaning component is installed below the pressure roller 2. The scraper 23 can effectively clean the dust on the surface of the pressure roller 2, reduce pollution and improve product quality during artificial leather processing. The scraper 23 can be moved through the fixed plate 12 to separate the scraper 23 from the pressure roller 2 to avoid long-term contact and wear on the pressure roller 2.

[0037] Working principle: First, when it is necessary to restrict the position of the artificial leather, start the motor 4. The motor 4 drives the bidirectional screw 14 to rotate. The rotation of the bidirectional screw 14 causes the outer moving rod 8 to move. The moving rod 8 moves on the slide rod 17 to change its position, corresponding to the width of the artificial leather. The artificial leather is fixed by the limiting block 7. After setting, the artificial leather slides within the limiting block 7. The limiting block 7 supports the movement of the artificial leather through the internal roller 20, reducing friction on the artificial leather and avoiding damage to the artificial leather due to friction.

[0038] Secondly, after long-term use, a lot of dust will be generated on the surface of the pressure roller 2. If it is not cleaned, it will be transferred to the artificial leather. It is necessary to pull the pull ring 9 to pull the pin 26 out of the pin hole 11 inside the bracket 1, so that the fixing plate 12 can be moved. The fixing plate 12 drives the crossbar 22 on one side to move inside the fixing rod 15 fixed inside the bracket 1. The crossbar 22 moves and the position of the scraper 23 is adjusted so that the scraper 23 is located on one side of the pressure roller 2 to scrape the dust on the surface of the pressure roller 2.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
