Abstract
Description
Technical Field
[0001] This utility model relates to the field of tension roller frame technology, and more specifically to a tension roller frame for biodegradable film production. Background Technology
[0002] Biodegradable films are film materials that degrade in the natural environment through microbial action or ultraviolet radiation. Their core characteristic is retaining the properties of traditional plastics while possessing environmentally friendly degradation capabilities. Tensioner rollers are frequently used and replaced during the production of biodegradable films. These rollers are typically made of stainless steel, are about 2 meters long, and are therefore quite heavy. Replacement tensioner rollers are usually placed on roller frames, which are moved between equipment for easy transport and replacement. However, traditional roller frames have some design and usage shortcomings. For example, the tensioner rollers are not securely fixed to the roller frame, making them prone to slipping or falling during transport, leading to safety hazards and reduced production efficiency. Furthermore, when retrieving tensioner rollers from the take-up roller frame, it is impossible to lift them upwards, requiring operators to expend considerable physical effort to retrieve them, impacting operational efficiency.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The tension roller frame for biodegradable film production involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example 1: like Figure 1-6 As shown, a tensioning roller frame for biodegradable film production includes a base 1, a roller frame body 2 fixedly mounted on the top of the base 1, multiple limiting grooves 21 on the front and rear sides of the top of the roller frame body 2, the top of the roller frame body 2 and the bottom of the inner wall are stepped, multiple tensioning rollers 3 are arranged inside the upper part of the roller frame body 2, and multiple arc-shaped limiting covers 4 are arranged on the front and rear sides of the top of the roller frame body 2. The ends of the tensioning rollers 3 are located inside the limiting grooves 21 and the arc-shaped limiting covers 4. The left side of the arc-shaped limiting cover 4 is connected to the top of the roller frame body 2 by a hinge, and the right side of the arc-shaped limiting cover 4 is fixedly connected to an L-shaped locking block 41. A protective groove 43 is opened on one side of the inner wall of the L-shaped locking block 41, and a stop is slidably connected to the left side of the protective groove 43. Plate 44, baffle 44, the four corners of the left side are fixedly connected with insert rods 45, the top of the roller frame body 2 is fixedly connected with multiple positioning blocks 42, the positioning blocks 42 are located inside the L-shaped locking block 41, the right side of the positioning block 42 is provided with an insertion port 421, the outer wall of the insert rod 45 is inserted into the insertion port 421, the four corners of the right side of baffle 44 are fixedly connected with straight rods 46, the right side of the L-shaped locking block 41 is provided with a handle 48, the outer wall of the straight rod 46 is slidably sleeved on the right side of the arc-shaped limiting cover 4, the right end of the straight rod 46 is fixedly connected to the left side of the handle 48, the outer wall of the straight rod 46 is movably sleeved with a spring 47, the left end of the spring 47 is fixedly connected to the left side of baffle 44, and the right end of the spring 47 is fixedly connected to the right side of the inner wall of the protective groove 43.
[0021] In this embodiment, when it is necessary to fix the tension roller 3, the operator first places both ends of the tension roller 3 into the limiting grooves 21 on the front and rear sides of the top of the roller frame body 2, and then rotates the arc-shaped limiting cover 4 around the hinge so that it covers the top of the tension roller 3. At this time, the L-shaped locking block 41 will move to the position of the positioning block 42. The operator pulls the handle 48, and the handle 48 drives the straight rod 46, the baffle 44 and the insertion rod 45 to move to the right. At the same time, the baffle 44 compresses the spring 47. When the top of the inner wall of the L-shaped locking block 41 moves to the top of the positioning block 42, the insertion rod 45 is aligned with the insertion port 421 on the right side of the positioning block 42. The handle 48 is released, and under the elastic force of the spring 47, the baffle 44 moves to the left, and the insertion rod 45 is inserted into the insertion port 421, thereby fixing the L-shaped locking block 41 on the positioning block 42. The arc-shaped limiting cover 4 and the limiting groove 21 are used to limit and protect the end of the tensioning roller 3, ensuring that the tensioning roller 3 will not slip or fall during the transfer process.
[0022] Example 2: like Figure 1-6 As shown, multiple electric telescopic rods 5 are fixedly installed on the bottom of the inner wall of the roller frame body 2. The telescopic ends of the electric telescopic rods 5 are fixedly connected to anti-slip limit covers 6. The bottom of the tension roller 3 is located inside the anti-slip limit cover 6. Multiple guide telescopic rods 7 are fixedly connected to the bottom of the inner wall of the roller frame body 2. The telescopic ends of the guide telescopic rods 7 are fixedly connected to the bottom of the anti-slip limit cover 6. A power supply box 11 is fixedly installed on the right side of the top of the base 1. A battery is installed inside the power supply box 11. A back plate 9 is fixedly installed on the left side of the top of the base 1. A pusher 10 is fixedly installed on the upper left side of the back plate 9. A control panel 12 is fixedly installed on the front of the roller frame body 2. Casters 8 are installed at the four corners of the bottom of the base 1.
[0023] In this embodiment, when the tension roller 3 needs to be retrieved, the operator activates the electric telescopic rod 5 via the control panel 12. The telescopic end of the electric telescopic rod 5 extends upward, causing the anti-slip limit cover 6 to move upward. Since the guide telescopic rod 7 guides and stabilizes the movement of the anti-slip limit cover 6, the anti-slip limit cover 6 can smoothly lift the tension roller 3 upward, making it convenient for the operator to retrieve, reducing the operator's physical burden and improving work efficiency. The battery in the power box 11 provides power to the electric telescopic rod 5 and the control panel 12, ensuring that the entire device can operate normally. The back plate 9, push frame 10, and casters 8 facilitate the operator to move the device between equipment. The casters 8 are equipped with brake components. When the device moves to the designated position, the casters 8 can be locked by the brake components to prevent the device from slipping during operation and ensure the stability of the device when parked.
[0024] In summary, as Figure 1-6As shown, this type of tension roller frame for biodegradable film production is used by placing both ends of the tension roller 3 into the limiting groove 21 at the top of the roller frame body 2. Then, the arc-shaped limiting cover 4 is rotated via a hinge to cover the ends of the tension roller 3. At this time, the L-shaped locking block 41 moves to above the positioning block 42. By pulling the handle 48, the straight rod 46 and the baffle 44 are driven to compress the spring 47, so that the insertion rod 45 is aligned with the insertion port 421 on the right side of the positioning block 42. After releasing the handle 48, the rebound force of the spring 47 pushes the insertion rod 45 into the insertion port 421, thus completing the fixing of the arc-shaped limiting cover 4. When the tension roller 3 needs to be removed, the operator only needs to pull the handle 48 again to disengage the insertion rod 45 from the insertion port 421, which will open the arc-shaped limiting cover 4. At this time, the electric telescopic rod 5 is activated through the control panel 12. The electric telescopic rod 5 pushes the anti-slip limiting cover 6 upward to lift the tension roller 3. The guide telescopic rod 7 extends and retracts synchronously to maintain the stable lifting and lowering of the anti-slip limiting cover 6, so that the tension roller 3 is smoothly lifted to a height that is easy to pick up. The casters 8 at the bottom of the base 1 facilitate the overall movement. The push frame 10 and the back plate 9 make it easy for the operator to push the device to move, which facilitates the transfer of the tension roller 3.
