Description

Technical Field

[0001] This utility model belongs to the field of membrane material production and processing technology, and in particular relates to a material pulling roller for membrane processing. Background Technology

[0002] In the field of membrane processing, the automation and efficiency improvement of production equipment have always been the core pursuit of the industry. Membranes are mainly used in many fields such as packaging materials and functional materials. In the membrane production process, especially in the film stretching process, a high-precision, high-efficiency and stable material stretching technology is required to ensure the quality of the membrane and production efficiency. Traditional material stretching systems usually have problems such as high energy consumption, insufficient stability, waste of membrane material and low production efficiency. In particular, when dealing with membranes of different thicknesses and materials, existing material stretching devices often need to be adjusted multiple times or even replaced with different specifications of material stretching components to adapt to different processing requirements. This not only increases production costs and time costs, but also limits processing flexibility.

[0003] When existing material pulling rollers are in operation, the end caps at both ends may loosen due to prolonged operation and rotation. This causes additional vibrations during operation, which can lead to a misalignment of the roller's axis, resulting in uneven material conveying and affecting production efficiency and product quality. Utility Model Content

[0004] This invention addresses the problem in the prior art where prolonged operation of the material pulling roller causes the end caps at both ends to loosen, resulting in additional vibration during operation. The following technical solution is proposed:

[0006] As a preferred embodiment of the above technical solution, the ends of the two fixed supports furthest from the first bearing are both fixedly connected to the inner wall of the roller.

[0007] As a preferred embodiment of the above technical solution, a roller is fixedly connected to one end of each of the two end caps.

[0008] As a preferred embodiment of the above technical solution, the positions of the four telescopic rods are all parallel to the positive and negative lead screws.

[0009] As a preferred embodiment of the above technical solution, the outer sides of the positive and negative lead screws are connected to the two rollers by an interference fit with second bearings, and the outer sides of the two second bearings are fixedly connected with support frames. The inner walls of the rollers are provided with grooves at the positions corresponding to the support frames.

[0010] As a preferred embodiment of the above technical solution, one end of the positive and negative lead screw is integrally formed with a rotary handle inside the roller shaft.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention utilizes the rotating screws inside the roller, and through the action of the telescopic rod fixedly connected to one end of the end cap, the rotating screws cause the end cap to move left and right, thus avoiding angular displacement of the end cap during movement. This ensures that the end cap is fixed in the corresponding position inside the roller, preventing the end caps from loosening during the operation of the material pulling roller, guaranteeing the stability of material conveying during the pulling process, and improving the production efficiency of film processing.

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example 1

[0019] This utility model provides a material pulling roller for film processing, such as Figures 1-3As shown, the roller includes: a roller 1, inside which a positive and negative lead screw 4 is installed. A first bearing 5 is connected to the middle portion of the outer side of the positive and negative lead screw 4 via an interference fit. Fixed supports 6 are fixedly connected to the top and bottom of the first bearing 5. Telescopic rods 14 are symmetrically fixedly connected to the ends of the two fixed supports 6 away from the first bearing 5. The ends of the four telescopic rods 14 away from the fixed supports 6 are fixedly connected to one end of an end cap 2. The ends of the two fixed supports 6 away from the first bearing 5 are fixedly connected to the inner wall of the roller 1. By firmly fixing the two fixed supports 6 to the ends away from the first bearing 5 and fixing both fixed supports 6 to the inner wall of the roller 1, the first bearing 5 is fixed at the middle position of the positive and negative lead screw 4. Since the inner ring of the first bearing 5 is fixedly sleeved on the outer side of the positive and negative lead screw 4, the positive and negative lead screw 4 is thus fixed inside the roller 1, preventing it from shifting. The positive and negative lead screws 4 are connected to sliders 7 at symmetrical positions on both ends of the first bearing 5 via threads. Connecting shafts 8 are fixedly connected inside each slider 7. Mounting blocks 9 are fixedly connected to the ends of the connecting shafts 8 away from the sliders 7. End caps 2 are provided at both ends of the roller 1. Roller shafts 3 are fixedly connected to one end of each end cap 2. Mounting blocks 9 are fixedly installed at one end of each end cap 2. By rotating the positive and negative lead screws 4, the two sliders 7 move towards each other simultaneously. Combined with the action of the connecting shafts 8, this pulls the end caps 2 at one end of the mounting blocks 9, thus fixing the end caps 2 in their corresponding positions inside the roller 1. Second bearings 10 are connected to the outside of the positive and negative lead screws 4 inside the two roller shafts 3 via interference fit. Support frames 11 are fixedly connected to the outside of each of the two second bearings 10. Grooves 12 are provided on the inner wall of the roller shafts 3 at positions corresponding to the support frames 11.

[0020] like Figure 2 and Figure 3 As shown, one end of the positive and negative lead screw 4 is integrally formed with a handle 13 inside the roller shaft 3. The handle 13 makes it easy for the operator to rotate the positive and negative lead screw 4 inside the roller 1, making it easy and convenient for the operator to perform linkage operation. The handle 13 reduces the use of additional parts, thereby simplifying the internal equipment structure of the roller 1 and reducing the maintenance cost of the pulling roller.

[0021] Working principle: In actual use, by rotating the handle 13 inside the roller shaft 3, the rotation of the handle 13 drives the positive and negative lead screw 4 inside the roller 1 to rotate. Through the first bearing 5 fixedly installed inside the roller 1, the rotation of the positive and negative lead screw 4 drives the slider 7, connecting shaft 8 and end cover 2 to rotate as a whole. Since one end of the end cover 2 is fixedly connected to the telescopic rod 14, and the end of the telescopic rod 14 away from the end cover 2 is fixedly connected to the fixed support 6, the end cover 2 can only move left and right during movement. Combined with the threaded connection between the slider 7 and the positive and negative lead screw 4, this allows the positive and negative lead screw to rotate. When lever 4 is engaged, it causes the two connecting shafts 8 to retract, thereby moving the end caps 2 closer to the first bearing 5. Then, the operator controls the rotation of the handle 13, causing the two end caps 2 to move simultaneously to their corresponding positions inside the roller 1, thus fixing the two end caps 2 inside the roller 1. This prevents the end caps 2 from becoming loose during the operation of the pulling roller, further preventing vibration caused by the loose end caps 2 during the operation of the pulling roller. This ensures that the axis of the pulling roller does not deviate during operation, allowing the film processing workflow to proceed smoothly and improving production efficiency and product quality.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
