Abstract
Description
Technical Field
[0001] This utility model relates to the field of traction machine technology, and in particular to an adjustable traction machine clamping mechanism. Background Technology
[0002] A traction machine is a mechanical device that uses traction force to move or pull an object to a target position. There are many types of traction machines, and roller traction machines are one of them. They are mainly composed of upper and lower rollers and are powered by a motor to achieve material traction and conveying. They can traction materials such as film, paper, and fabric.
[0003] The roller traction machine clamps the material by bringing two sets of rollers closer together. Then, the material is propelled forward smoothly by the rotation of the rollers and the friction force. The existing roller structure for clamping materials is relatively simple. When the roller rotation speed is too fast, the material will move laterally due to inertia, causing the material to deviate from the predetermined processing path. This will affect the uniformity of the material during subsequent processing and the quality of the finished product. To address this problem, we propose an adjustable traction machine clamping mechanism. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable traction machine clamping mechanism.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An adjustable traction machine clamping mechanism includes a traction machine frame. A fixed roller is rotatably connected to the inner side of the traction machine frame, and a movable roller is provided above the fixed roller. A limiting plate is sleeved on the outer side of the fixed roller and the movable roller, and a connecting rod is inserted laterally on the side of the limiting plate. The end of the connecting rod is connected to the inner wall of the traction machine frame. A U-shaped rod is connected to the side of the limiting plate, and a sliding block is sleeved on the outer side of the U-shaped rod. An insertion rod is connected to the side of the sliding block. Connecting grooves adapted to the insertion rod are opened laterally at equal intervals inside the connecting rod. A rotating plate is provided on the side of the limiting plate.
[0007] Preferably, the rotating plate is configured as a rectangular structure, and the inner side of the rotating plate is provided with a folding structure.
[0008] Preferably, the folding structure includes fixing blocks, and the rotating plate is symmetrically connected to the side of the fixing blocks, and the fixing blocks are connected to each other by a rotating rod. The rotating rod is movably inserted into the inside of the limiting plate, and the limiting plate is laterally inserted into the side of the limiting plate, and the end of the limiting rod is connected to a linkage block. The rotating rod has a fixing groove inside that matches the limiting rod.
[0009] Preferably, the rotating plate has a U-shaped block on its side, and the inner side of the U-shaped block is connected to a rotating roller via a bearing.
[0010] Preferably, the upper and lower ends of the rotating roller are symmetrically connected to mounting plates, and the interior of the mounting plates is connected to the side of the rotating plate by bolts.
[0011] Preferably, two sets of sliding blocks are sleeved on the outer side of the U-shaped rod, and the two sets of sliding blocks are symmetrically distributed about the central axis of the U-shaped rod.
[0012] Preferably, a spring connects the upper and lower sets of sliding blocks, and the spring is movably sleeved on the outside of the U-shaped rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This device is equipped with connecting rods and limiting plates. During use, the distance between the two sets of connecting rods can be adjusted by the cooperation of the sliding block and the insertion rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-5 An adjustable traction machine clamping mechanism includes a traction frame 1. A fixed roller 2 is rotatably connected to the inner side of the traction frame 1, and a movable roller 3 is provided above the fixed roller 2. The traction frame 1, the fixed roller 2, and the movable roller 3 together constitute a roller traction machine in the prior art. The height adjustment principle of the movable roller 3 and the transfer principle of the movable roller 3 and the fixed roller 2 are prior art and will not be described in detail here. A limiting plate 4 is sleeved on the outer side of the fixed roller 2 and the movable roller 3, and a connecting rod 5 is inserted laterally on the side of the limiting plate 4. Since the limiting plate 4 is set as a frame structure, it can meet the requirements of the movable roller 3. Normal up and down adjustment, the end of the connecting rod 5 is connected to the inner wall of the traction frame 1. Through the connection of the connecting rod 5, the lateral guidance of the limiting plate 4 can be realized, thereby satisfying the stable lateral movement of the limiting plate 4. The side of the limiting plate 4 is connected to a U-shaped rod 6, and a sliding block 7 is sleeved on the outside of the U-shaped rod 6. The side of the sliding block 7 is connected to an insertion rod 8. The inside of the connecting rod 5 is equidistantly provided with connecting grooves that are compatible with the insertion rod 8. The side of the limiting plate 4 is provided with a rotating plate 10. Through the opening of multiple sets of connecting grooves, it is convenient for the staff to limit and fix the limiting plate 4 and the rotating plate 10 pushed to the appropriate position.
[0024] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 It can be seen that the rotating plate 10 is set as a rectangular structure, and the inner side of the rotating plate 10 is provided with a folding structure. By using the large rectangular rotating plate 10, the lateral limiting effect on the material can be improved.
[0025] Furthermore, refer to Figure 2 and Figure 4It can be seen that the folding structure includes a fixing block 11. The fixing blocks 11 are symmetrically connected to the side of the rotating plate 10, and the fixing blocks 11 are connected to each other by a rotating rod 12. The rotating rod 12 is movably inserted into the inside of the limiting plate 4. The limiting plate 4 has a limiting rod 13 inserted laterally on its side, and the end of the limiting rod 13 is connected to a linkage block 14. The rotating rod 12 has a fixing groove that matches the limiting rod 13. During use, the limiting plate 4 has a receiving groove that matches the rotating rod 12, thereby meeting the rotation requirements of the rotating rod 12 and the rotating plate 10. By inserting the limiting rod 13 on the side of the limiting plate 4, and since the limiting rod 13 is embedded in the inside of the rotating rod 12, it is easy to limit the rotating rod 12 when it is rotated to a suitable angle. Since there are four sets of fixing grooves, the rotating plate 10 can be folded and stored after use.
[0026] Furthermore, refer to Figure 1 and Figure 5 It can be seen that the side of the rotating plate 10 is provided with a U-shaped block 15, and the inner side of the U-shaped block 15 is connected to a rotating roller 16 through a bearing. In use, by rotating the rotating roller 16, the edge of the material can be protected and guided, and the limiting resistance of the material can be effectively reduced.
[0027] Furthermore, refer to Figure 5 It can be seen that the upper and lower ends of the rotating roller 16 are symmetrically connected with mounting plates 17, and the interior of the mounting plates 17 is connected to the side of the rotating plate 10 by bolts. During use, the mounting plates 17 and bolts can be used to facilitate the quick disassembly and replacement of the damaged rotating roller 16 by the staff, thereby improving the convenience of maintenance of this device.
[0028] Furthermore, refer to Figure 2 and Figure 3 It can be seen that two sets of sliding blocks 7 are sleeved on the outer side of the U-shaped rod 6, and the two sets of sliding blocks 7 are symmetrically distributed about the central axis of the U-shaped rod 6. Since there are two sets of sliding blocks 7 and insertion rods 8, there are also two sets of connecting rods 5. By setting two sets of connecting rods 5, the stable lateral movement of the limiting plate 4 can be effectively guaranteed, and by setting two sets of insertion rods 8, the limiting effect on the limiting plate 4 can be effectively improved.
[0029] Furthermore, refer to Figure 4 It can be seen that a spring 9 is connected between the upper and lower sets of sliding blocks 7, and the spring 9 is movably sleeved on the outside of the U-shaped rod 6. During use, the spring 9 connected between the sliding blocks 7 can effectively ensure the tightness of the insertion rod 8 when it is inserted into the connecting groove inside the connecting rod 5.
[0030] Working Principle: When using this invention, the operator first places the device in a suitable position, then places the material to be pulled between the fixed roller 2 and the movable roller 3. By rotating the screw inserted inside the traction frame 1, the distance between the movable roller 3 and the fixed roller 2 is adjusted. After adjustment, the operator pulls the sliding blocks 7, which are simultaneously on the same horizontal line, closer together, causing the insertion rods 8 connected to their sides to be simultaneously stressed. This allows the insertion rods 8 to be pulled out from inside the connecting rod 5, releasing the restriction on the limiting plate 4. The operator can then move the limiting plate 4 laterally to move the rotating plate 1... Move the device to the edge of the material. After the movement is complete, the operator can stop pulling the sliding block 7, so that the insertion rod 8 can be inserted into the corresponding connecting groove inside the connecting rod 5 to limit the position of the limiting plate 4 and the rotating plate 10. After adjusting the position of the two sets of limiting plates 4, the material can be laterally limited. Then the operator can connect the device to the power supply. Since there is friction between the surface of the fixed roller 2 and the movable roller 3 and the material, the material will be "bitten" by the roller surface and move forward with the rotation of the roller, thereby realizing the traction and conveying of the material. The above is the complete working principle of this utility model.

As long as they can achieve their beneficial effects, they can be implemented, so they will not be described in detail.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
