Description

Technical Field

[0001] The utility model belongs to the technical field of PVC film processing and relates to a PVC film traction device. Background Art

[0002] Polyvinyl chloride film, commonly known as PVC film, is formed by adding functional processing aids such as plasticizers, stabilizers, and lubricants to PVC resin and then calendering it into a film. The film typically has a thickness of 0.08 to 0.2 mm. PVC sheets thicker than 0.25 mm offer excellent thermal insulation and light transmittance. During the production and processing of PVC film, specialized traction devices are required to transport it. During the upward conveying of PVC film, if it breaks or cuts, the lower PVC film must be manually pulled up again. Therefore, to facilitate the traction process, a PVC film traction device is necessary. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and to propose a PVC film pulling device.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A PVC film traction device includes a mounting frame, characterized in that the mounting frame includes an upper area and a lower area, the lower area is provided with a feed roller group and a guide roller group 1 that are rotatably installed in sequence, the upper area is provided with a guide roller group 2 and a discharge roller group that are rotatably installed, the guide roller group 2 includes a main roller and a secondary roller, the main roller is relatively fixedly installed on the mounting frame, and the secondary roller is relatively rotatably installed on the mounting frame by swinging hand 1, a guide rail is provided between the upper area and the lower area, a clamping mechanism is slidably installed on the guide rail by a driving member, the clamping mechanism includes a mounting member, a fixed roller 1 is installed on the mounting member, a fixed roller 2 is provided next to the fixed roller, and the fixed roller 2 is swung and installed on the mounting member by swinging hand 2.

[0005] The working principle of the utility model is as follows: under normal working conditions, the PVC film is introduced into the guide roller group 1 through the feed roller group, transported upward, introduced into the guide roller group 2 in the upper area, and then guided to the discharge roller group for discharge; when the PVC film is broken or cut during the transportation from bottom to top, the end of the PVC film in the lower area is fixed on the clamping mechanism, and the clamping mechanism is driven by the driving member to slide upward along the guide rail. During this period, the auxiliary roller is separated from the main roller under the control of the swing hand 1, so that the clamping mechanism can pass between the main roller and the auxiliary roller. When the clamping mechanism moves to the end of the highest point of the guide rail, the swing hand 1 controls the auxiliary roller to fit with the main roller to clamp the PVC film. Finally, the clamping mechanism releases the PVC film and allows it to fall to the discharge roller group to complete the bottom-up traction of the PVC film.

[0006] The guide roller group 1 and the guide roller group 2 adopt the same main roller and auxiliary roller structure, wherein the main roller is larger in size and connected to an external drive device to become an active roller, and the auxiliary roller is smaller in size and serves as a driven roller.

[0007] The above structure is adopted to increase the conveying efficiency.

[0008] The first fixed roller and the second fixed roller are rubber rollers.

[0009] The above structure provides better grasping ability.

[0010] A limiting member is installed below the discharging roller group.

[0011] The above structure is adopted to avoid the auxiliary roller of the second guide roller group from contacting with the discharge roller group.

[0012] The guide rail is arranged to be inclined upward.

[0013] The above structure makes the overall conveying smoother and facilitates the PVC film to fall into the discharge roller group.

[0014] Compared with the prior art, the present PVC film traction device has the following advantages: the present invention provides an upward inclined traction mechanism to replace manual traction of the broken or cut PVC film from bottom to top, making the traction process more convenient.

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figure 1-4As shown, the PVC film traction device includes a mounting frame 1, and the mounting frame 1 includes an upper area and a lower area. A feed roller group 2 and a guide roller group 6 are installed in the lower area in sequence, and a guide roller group 2 and a discharge roller group 3 are installed in the upper area in sequence. The guide roller group 2 includes a main roller 4 and an auxiliary roller 5. The main roller 4 is relatively fixedly installed on the mounting frame 1, and the auxiliary roller 5 is relatively rotatably installed on the mounting frame 1 through a swinging hand 7. A guide rail 8 is provided between the upper area and the lower area, and a clamping mechanism is slidably installed on the guide rail 8 through a driving member. The clamping mechanism includes a mounting member 9, a fixed roller 10 is installed on the mounting member 9, and a fixed roller 2 11 is provided next to the fixed roller 10. The fixed roller 2 11 is swung and installed on the mounting member 9 through a swinging hand 2 12.

[0022] In the present invention, both the first swinging hand 7 and the second swinging hand 12 adopt the existing swing driving device.

[0023] The driving parts of the present invention adopt existing products, such as linear motors and the like.

[0024] The clamping device of the present invention can be stopped at any position on the guide rail 8 that does not interfere with the transportation of the PVC film when clamping is not required.

[0025] The guide roller group 1 6 and the guide roller group 2 use the same main roller 4 and auxiliary roller 5 structure, wherein the main roller 4 is larger in size and is connected to an external drive device to become an active roller, and the auxiliary roller 5 is smaller in size and serves as a driven roller.

[0026] The fixed roller 10 and the fixed roller 2 11 are rubber rollers.

[0027] In the present invention, the fixed roller 10 and the fixed roller 2 11 are initially kept separated and do not contact the PVC film during the PVC film conveying process.

[0028] A limiting member 13 is installed below the discharge roller group 3 .

[0029] The limiting member 13 in the present invention is made of rubber material, which plays a buffering role and avoids friction.

[0030] The guide rail 8 is arranged to be inclined upward.

[0031] The working principle of the present invention is as follows: under normal working conditions, the PVC film is introduced into the guide roller group 1 6 through the feed roller group 2 for upward transportation, and then introduced into the guide roller group 2 in the upper area for secondary guidance to the discharge roller group 3 for output; when the PVC film is broken or cut during the transportation from bottom to top, the end of the PVC film in the lower area is fixed on the clamping mechanism, and the clamping mechanism is driven by the driving member to slide upward along the guide rail 8. During this period, the auxiliary roller 5 is separated from the main roller 4 under the control of the swing hand 7, so that the clamping mechanism can pass between the main roller 4 and the auxiliary roller 5. When the clamping mechanism moves to the end of the highest point of the guide rail 8, the swing hand 7 controls the auxiliary roller 5 to fit with the main roller 4 to clamp the PVC film. Finally, the clamping mechanism releases the PVC film and allows it to fall to the discharge roller group 3 to complete the bottom-up traction of the PVC film.

[0032] In the utility model, each mechanism is connected and driven by using the existing technology, and synchronous control is achieved through a control panel.
