Abstract
Description
Technical Field
[0001] This application relates to the field of rewinding roll technology, and more specifically, to a rewinding roll. Background Technology
[0002] PE protective film is the simplest high-molecular organic compound and is widely used in daily life. After the production and processing of PE protective film is completed, it needs to be rewound by rewinding rollers to improve its ease of use.
[0003] The prior art publication CN220596552U discloses a rewinding inspection device for PE protective film, including a rewinding roller and an unwinding roller on one side of the rewinding roller, both of which are located on a machine base. This invention utilizes a push-push cylinder and two flipping frames to simultaneously flip up two first flattening seats. Simultaneously, the first and second flattening seats push the PE film to the upper and lower sides, allowing the PE film to be smoothly and wrinkle-free wound onto the rewinding roller after passing through the arc-shaped first and second flattening seats, without damaging the PE film during the flattening process. The adsorption slots on the first and second flattening seats adsorb the passing PE film, removing dust or debris adhering to its surface during the rewinding process. The suction force generated by the adsorption further reduces wrinkles on the PE film.
[0004] Although the device has many beneficial effects, it still has the following problems: when the operator connects the rewinding roll to the external drive equipment, it is difficult to install the heavy rewinding roll in sections, which makes the installation more laborious and increases the difficulty of the operator installing the rewinding roll. In view of this, we propose a rewinding roll. Utility Model Content
[0005] This application provides a rewinding roller that solves the technical problem in the prior art where it is difficult to install the heavy rewinding roller in sections when the operator connects it to the external drive equipment, making the installation laborious and increasing the difficulty of installation. This invention facilitates the segmented installation of the rewinding roller, prevents the heavy overall weight of the rewinding roller from causing excessive installation effort, and thus reduces the difficulty of installation for the operator.
[0006] This application provides a rewinding roll, including: a toothed roll;
[0007] Both ends of the toothed roller are fixedly connected to rotating rods. Multiple connecting rings are slidably sleeved on the outer side of the toothed roller. Multiple tooth grooves are opened on the inner wall of the connecting rings to adapt to the toothed roller. A positioning mechanism for positioning the connecting rings is sleeved on the outer side of the rotating rods.
[0008] The positioning mechanism includes a retaining ring, which is detachably connected to the outside of the rotating rod. The retaining ring is composed of a first plate and a second plate, and the first plate and the second plate are detachably connected.
[0009] By adopting the above technical solution, when workers need to install the rewinding roller and the external drive equipment, they can simply lift the toothed roller and the rotating rod first. After the rotating rod is connected to the drive equipment, the connecting ring is then placed on the outside of the toothed roller in sequence, and finally the retaining ring is installed on the outside of the rotating rod to block the connecting ring. This makes it convenient for workers to install the rewinding roller in sections and prevents the rewinding roller from being too heavy to install.
[0010] Optionally, a groove is provided on one side of the first plate, a horizontal plate is fixedly connected to one side of the second plate, an insert block is fixedly connected to one side of the horizontal plate, and springs are fixedly connected to the top and bottom of the inner wall of the groove, with a limiting block for blocking the insert block fixedly connected to one end of the spring.
[0011] By adopting the above technical solution, when the worker inserts the plug between the two limiting blocks, as the plug is gradually inserted, it can push the two limiting blocks to move away from each other and compress the spring. After the plug separates from the limiting block, the compressed spring can rebound and drive the limiting block to reset and move. This makes it easier to use the limiting block and the plug for quick positioning and improves the worker's installation efficiency.
[0012] Optionally, the cross-section of the insert block is an isosceles trapezoid, the cross-section of the limiting block is a right trapezoid, and the inclined surface of the limiting block away from the spring is parallel to the inclined surface of the insert block near the limiting block.
[0013] By adopting the above technical solution, due to the design of the inclined surface of the insert block and the inclined surface of the limiting block, when the insert block moves horizontally in the groove, it can push the two limiting blocks to move vertically in a direction away from each other.
[0014] Optionally, a through groove is provided on the other side of the first plate, and a protruding plate is slidably connected in the through groove, and the protruding plate is fixedly connected to the limiting block.
[0015] By adopting the above technical solution, when the limiting block moves, it can drive the convex plate to move in the through groove, thereby ensuring that the limiting block moves stably vertically. When the staff needs to disassemble or assemble the retaining ring, they only need to pull the convex plate to drive the limiting block to move.
[0016] Optionally, the total length of the cross plate and the insert is equal to the length of the inner side of the groove.
[0017] By adopting the above technical solution, since the total length of the horizontal plate and the insert is equal to the length of the inner side of the groove, the first plate and the second plate can be prevented from moving left or right at will after they are connected.
[0018] Optionally, limiting plates are fixedly connected to the top and bottom of the horizontal plate, the width of the horizontal plate is equal to the width of the inner side of the groove, and the total height of the horizontal plate and the two limiting plates is equal to the height of the inner side of the groove.
[0019] By adopting the above technical solution and setting a limiting plate and a horizontal plate, when the worker inserts the horizontal plate and the limiting plate into the groove, the insert block can be aligned precisely between the two limiting blocks, which facilitates the worker to quickly assemble the retaining ring.
[0020] Optionally, slots are provided on both sides of the outer wall of the rotating rod, and the inner walls of the first plate and the second plate are fixedly connected with locking blocks for cooperating with the slots.
[0021] By adopting the above technical solution and setting the slot and the block, when the worker assembles the first plate and the second plate into a retaining ring, the block can be inserted into the inside of the slot. This makes it easier for the rotating rod to rotate together with the retaining ring through the cooperation of the slot and the block during the subsequent winding process, and prevents the retaining ring from falling off the outside of the rotating rod.
[0022] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:
[0023] 1. By setting toothed rollers, connecting rings and positioning mechanisms, when workers need to install rewinding rollers, it is convenient for them to install the rewinding rollers in sections, preventing the rewinding rollers from being too heavy to install due to their overall weight, and thus reducing the difficulty of installation for workers.
[0024] 2. By setting up insert blocks, limit blocks, and springs, when workers assemble the retaining ring, insert blocks are inserted between two limit blocks and pushed to move. Using the limit blocks and insert blocks for quick positioning, workers can quickly connect the first plate and the second plate, improving the installation efficiency of workers.
[0025] 3. By setting up a locking block and a locking slot, when the worker assembles the first plate and the second plate into a retaining ring, the locking block can be inserted into the inner side of the locking slot. This makes it easier for the rotating rod to rotate together with the retaining ring through the cooperation of the locking slot and the locking block during the subsequent winding process, and prevents the retaining ring from falling off the outside of the rotating rod.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.
[0033] Reference Figure 1 , Figure 2 and Figure 3 This application discloses a rewinding roller. The rewinding roller includes: a toothed roller 1;
[0034] Both ends of the toothed roller 1 are fixedly connected to rotating rods 2. Multiple connecting rings 4 are slidably sleeved on the outer side of the toothed roller 1. Multiple tooth grooves 5 are opened on the inner wall of the connecting rings 4 to adapt to the toothed roller 1. A positioning mechanism 3 for positioning the connecting rings 4 is sleeved on the outer side of the rotating rods 2.
[0035] The positioning mechanism 3 includes a retaining ring 31, which is detachably connected to the outside of the rotating rod 2. The retaining ring 31 is composed of a first plate 32 and a second plate 33, and the first plate 32 and the second plate 33 are detachably connected, which facilitates the workers to install the rewinding roller in sections and prevents the rewinding roller from being too heavy to install.
[0036] Reference Figure 4 and Figure 5 The first plate 32 has a groove on one side, and the second plate 33 has a horizontal plate 34 fixedly connected to one side. The horizontal plate 34 has an insert block 35 fixedly connected to one side. The top and bottom of the inner wall of the groove are both fixedly connected to springs 36. One end of the spring 36 is fixedly connected to a limiting block 37 for blocking the insert block 35, so that the workers can quickly connect the first plate 32 and the second plate 33.
[0037] Reference Figure 4 and Figure 5 The cross-section of the insert block 35 is an isosceles trapezoid, and the cross-section of the limiting block 37 is a right trapezoid. The inclined surface of the limiting block 37 away from the spring 36 is parallel to the inclined surface of the insert block 35 near the limiting block 37, so that when the insert block 35 is inserted between the two limiting blocks 37, the two limiting blocks 37 can be pushed to move in a direction away from each other.
[0038] Reference Figure 4 and Figure 5 A through groove is provided on the other side of the first plate 32, and a protruding plate 38 is slidably connected in the through groove. The protruding plate 38 is fixedly connected to the limiting block 37, so that the limiting block 37 can move vertically stably in the groove.
[0039] Reference Figure 4 and Figure 5 The total length of the horizontal plate 34 and the insert block 35 is equal to the length of the inner side of the groove, so that after the horizontal plate 34 and the insert block 35 are fully inserted into the inner side of the groove, the horizontal plate 34 and the insert block 35 can be prevented from moving left and right inside the groove.
[0040] Reference Figure 4 and Figure 5 Limiting plates 310 are fixedly connected to the top and bottom of the horizontal plate 34. The width of the horizontal plate 34 is equal to the width of the inner side of the groove, and the total height of the horizontal plate 34 and the two limiting plates 310 is equal to the height of the inner side of the groove. This makes it easy for the workers to quickly insert the insert block 35 between the two limiting blocks 37 when connecting the first plate 32 and the second plate 33.
[0041] Reference Figure 2 and Figure 4 The rotating rod 2 has slots on both sides of its outer wall. The inner walls of the first plate 32 and the second plate 33 are fixedly connected with locking blocks 39 for cooperating with the slots. So when the rotating rod 2 rotates, the locking blocks 39 can cooperate with the slots to drive the retaining ring 31 to rotate.
[0042] The implementation principle of a rewinding roller in this application embodiment is as follows: when the worker needs to install and move the rewinding roller, the rotating rod 2 and the toothed roller 1 are lifted so that the rotating rod 2 is connected to the output shaft of the external drive equipment. This connection can be achieved by welding or by opening a hole on the outside of the rotating rod 2 and connecting it with bolts.
[0043] Then, the workers can sequentially put multiple connecting rings 4 on the outside of the toothed roller 1 and push the connecting rings 4 to move until all the connecting rings 4 are installed. Then, the workers can place the first plate 32 and the second plate 33 on the outside of the rotating rod 2 and move the first plate 32 and the second plate 33 toward each other.
[0044] At this time, the second plate 33 drives the horizontal plate 34 and the insert block 35 to move. The insert block 35 and the horizontal plate 34 enter the groove until the insert block 35 enters between the two limiting blocks 37. As the insert block 35 moves, it can push the two insert blocks 35 to move away from each other and squeeze the spring 36 until the limiting plate 310 enters the inner side of the groove. At this time, the inclined surface of the insert block 35 no longer contacts the inclined surface of the limiting block 37, so that the squeezed spring 36 rebounds and drives the limiting block 37 to quickly reset and move. At this time, the insert block 35 is blocked by the two limiting blocks 37 and can hardly move out of the groove. At this time, the first plate 32 and the second plate 33 form a retaining ring 31 and are sleeved on the outside of the rotating rod 2.
[0045] To prevent the retaining ring 31 from moving arbitrarily outside the rotating rod 2, which would cause the connecting ring 4 to move arbitrarily outside the toothed roller 1, when assembling the first plate 32 and the second plate 33 into the retaining ring 31, the locking block 39 is inserted into the locking groove at the same time. This ensures the stability of the retaining ring 31 outside the rotating rod 2 and the stability of the connecting ring 4 outside the toothed roller 1.
[0046] When it is necessary to remove the rewinding roller, simply pull the convex plate 38 to move the limiting block 37 to compress the spring 36, so that the limiting block 37 is separated from the insert block 35. The worker can then remove the insert block 35 from the groove and separate the first plate 32, the second plate 33 and the rotating rod 2. Then, the multiple connecting rings 4 can be removed in sequence.
[0047] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
