Description

Technical Field

[0001] This application belongs to the technical field of light SPC floor production and processing, and particularly relates to a traction device for light SPC floor production. Background Art

[0002] The light SPC floor, also known as stone plastic composite floor, is currently widely used due to its excellent environmental protection performance, without any toxicity and no carcinogens such as formaldehyde. Therefore, how to improve the continuity, efficiency and product quality in the production process of light SPC floor has become a key issue of concern. In the production process of light SPC floor, although the role of the traction device is not directly related to the core links such as the material characteristics or production process of the floor, it is closely related to the material transmission, positioning and speed control on the production line. And material transmission is the key to ensuring the continuity and efficiency of the production process, and material positioning and speed control directly affect the quality of the product. Therefore, the traction device plays a crucial role in the production of light SPC floor. In the prior art, the commonly used traction device generally includes two upper and lower traction rollers. When in use, the light SPC floor passes between the two upper and lower traction rollers, and the driving mechanism drives the two traction rollers to rotate so as to realize the traction of the light SPC floor. At present, in order to improve the flexibility of the traction device, generally, the upper traction roller is driven to move up and down by a cylinder to control the gap distance between the two traction rollers, so that the traction device can be applicable to traction of various different thickness plates. Because it is necessary to control the up and down movement of the upper traction roller, for the convenience of installation, the driving mechanism needs to drive the upper traction roller and the lower traction roller separately, that is, the driving mechanism has two power elements to drive the upper traction roller and the lower traction roller to rotate respectively; or only the lower traction roller is driven, and the upper traction roller only follows the material to rotate passively during use, which may result in a speed difference between the upper traction roller and the lower traction roller, thus being not conducive to the accurate conveying of the light SPC floor.

[0031] An embodiment of this application provides a traction device for producing a lightweight SPC floor, as Figures 1 to 3 shown, including a mounting frame 1, an upper traction roller 2, a lower traction roller 3, a transmission assembly and a driving mechanism;

[0032] Adjusting cylinders 4 are respectively and fixedly provided at opposite ends of the mounting frame 1. Mounting blocks 5 are also respectively provided at opposite ends of the mounting frame 1. Mounting reserved openings 16 are provided at positions corresponding to the mounting blocks 5 on the mounting frame 1. The mounting blocks 5 are slidably clamped in the mounting reserved openings 16 in the up and down direction. And the mounting blocks 5 are arranged in one-to-one correspondence with the adjusting cylinders 4. The output ends of the adjusting cylinders 4 are fixedly connected to the corresponding mounting blocks 5 for driving the mounting blocks 5 to slide up and down relative to the mounting frame 1;

[0033] Opposite ends of the upper traction roller 2 are respectively rotatably connected to the two mounting blocks 5; the lower traction roller 3 is arranged parallel to the upper traction roller 2 and is located below the upper traction roller 2. Opposite ends of the lower traction roller 3 are rotatably connected to the mounting frame 1; during use, when the adjusting cylinder 4 drives the mounting block 5 to slide up and down along the mounting reserved opening 16, the upper traction roller 2 rotatably connected to the mounting block 5 also moves up and down together, so as to achieve the purpose of adjusting the traction gap between the upper traction roller 2 and the lower traction roller 3.

[0034] The transmission assembly includes a first passive transmission gear 6, a second passive transmission gear 7, an active transmission gear 8 and a tensioning gear 9. The first passive transmission gear 6, the second passive transmission gear 7, the active transmission gear 8 and the tensioning gear 9 are connected by a transmission chain 10. In actual application, when setting the transmission chain 10, it should be noted that the rotation directions of the first passive transmission gear 6 and the second passive transmission gear 7 are opposite to ensure that the upper traction roller 2 and the lower traction roller 3 can be pulled normally. During installation, the first passive transmission gear 6 is fixed to one end of the upper traction roller 2, the second passive transmission gear 7 is fixed to one end of the lower traction roller 3 and corresponds to the first passive transmission gear 6, the active transmission gear 8 is rotatably connected to the mounting frame 1 and is located on one side of the second passive transmission gear 7, a strip-shaped clamping hole 14 is provided on the mounting frame 1 at the other side of the second passive transmission gear 7, a movable block 11 is slidably clamped on the strip-shaped clamping hole 14, the tensioning gear 9 is rotatably connected to the movable block 11, and an elastic member 12 is further provided between the movable block 11 and the mounting frame 1 for pushing or pulling the movable block 11 to move in a direction away from the second passive transmission gear 7 to ensure that the tensioning gear 9 connected to the movable block 11 can continuously provide good tensioning force so as to ensure that the transmission chain 10 can have a good transmission effect. Among them, the function of the strip-shaped clamping hole 14 is mainly to slide and clamp the movable block 11, so in the actual application process, the strip-shaped clamping hole 14 can also be set as a strip-shaped clamping groove.

[0035] The driving mechanism includes a driving motor 13 , and an output end of the driving motor 13 is connected to the driving transmission gear 8 to drive the driving transmission gear 8 to rotate.

[0036] In order to facilitate the disassembly and assembly of the elastic member 12, a fixing member 15 is provided on the mounting frame 1 at a position corresponding to the movable block 11. The fixing member 15 is close to the strip-shaped card hole 14 and away from one end of the second passive transmission gear 7. One end of the elastic member 12 is fixed on the movable block 11, and the other end is fixed on the fixing member 15 to pull the movable block 11 to move in a direction away from the second passive transmission gear 7. Among them, the elastic member 12 and the fixing member 15 as well as the elastic member 12 and the movable block 11 are all detachably connected, so that the elastic member 12 can be replaced more quickly later. At the same time, during use, the elastic member 12 should be in a stretched state to ensure that it has a certain pulling force to ensure the tension of the transmission chain 10, thereby ensuring that the transmission chain 10 can have a good transmission effect. Therefore, in the actual application process, the specific position of the fixing member 15 can be adjusted according to the actual situation.

[0037] A first protective housing 17 is provided at a position on the mounting bracket 1 corresponding to the transmission assembly, and the first protective housing 17 is detachably sleeved outside the transmission assembly. A fixing bracket 18 is provided at a position on the mounting bracket 1 corresponding to the driving motor 13, and the driving motor 13 is mounted on the fixing bracket 18. A second protective housing 19 is provided at a position on the mounting bracket 1 corresponding to the driving mechanism, and the second protective housing 19 is detachably sleeved outside the driving mechanism.

[0038] As Figure 4 shown, in some other embodiments, the elastic member 12 is disposed between the movable block 11 and the inner wall of the strip-shaped card hole 14 for pushing the movable block 11 to move along a direction away from the second passive transmission gear 7. Among them, the connection between the elastic member 12 and the inner wall of the strip-shaped hole 14 and the connection between the elastic member 12 and the movable block 11 are both detachable, so as to facilitate the subsequent replacement of the elastic member 12 more quickly. At the same time, during use, the elastic member 12 should be in a compressed state to ensure that it has a certain thrust, so as to ensure the tension degree of the transmission chain 10, and further ensure that the transmission chain 10 can have a good transmission effect.
