Description

Technical Field

[0001] This utility model relates to the field of cling film cutting technology, specifically a cling film winding and cutting device. Background Technology

[0002] Plastic wrap is a common kitchen item, mainly used for food preservation and storage. It is also used for cleaning, surface protection, and other purposes. Plastic wrap cutting refers to dividing a large roll of plastic wrap into smaller or specific sizes of segments or rolls for easier use and carrying.

[0003] During the production process, large rolls of film material often need to be cut into films of appropriate width before being rewound. The slitting device mainly uses slitting blades installed on the rewinding equipment. During the high-speed rewinding process, the blades cut along the sliding path of the film material to achieve the purpose of slitting. The adjustment of the slitting width is mainly controlled by the distance between adjacent blades. When producing cling film of different widths, it is often necessary to adjust the spacing between the blades. Therefore, a slitting device that makes it easier to adjust the spacing can greatly reduce the difficulty of operation. Utility Model Content

[0004] The purpose of this invention is to provide a plastic wrap winding and cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes an end fixing plate and a slitting blade. The end fixing plates are provided in pairs and are fixed together by a crossbar. An annular sleeve is installed on the crossbar, and a blade holder is fixed at the bottom of the annular sleeve. The slitting blade is installed at the bottom of the blade holder. A horizontal groove is opened on the outer side of the crossbar, and a locking block adapted to the horizontal groove is opened on the inner side of the annular sleeve. The locking block is slidably connected in the horizontal groove, and a positioning component is provided between the annular sleeve and the crossbar.

[0006] Preferably, the positioning component includes a fixing hole and an insertion rod. The fixing holes are opened at the upper end of the crossbar and are evenly distributed. The insertion rod is slidably connected in the annular sleeve, and the bottom of the insertion rod is inserted into the corresponding fixing hole.

[0007] Preferably, the upper end of the insertion rod extends out of the annular sleeve and is fixed with an end plate, and a fixing spring is fixed between the end plate and the annular sleeve.

[0008] Preferably, a positioning groove is provided at the bottom of the horizontal groove, the width of the positioning groove is adapted to the width of the card block, and the position of the positioning groove is aligned with the position of the fixing hole.

[0009] Preferably, a scale line is provided on the crossbar and above the horizontal groove.

[0010] Preferably, bolt holes are provided at the four corners of the end fixing plate, and side frames are fixed on both sides of the end fixing plate. A pair of guide rollers are rotatably connected to each side frame, and the connection point of the guide rollers is aligned with the position of the slitting blade.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by inserting and pulling the insertion rod and deflecting the annular sleeve, the position of the annular sleeve can be easily adjusted to achieve the adjustment of the slitting spacing, without the need to disassemble and reinstall the slitting blade, which greatly simplifies the slot operation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: including an end fixing plate 1 and a slitting blade 41. The end fixing plate 1 is provided with a pair and is fixed between them by a crossbar 2. An annular sleeve 3 is installed on the crossbar 2. A blade holder 4 is fixed at the bottom of the annular sleeve 3. The slitting blade 41 is installed at the bottom of the blade holder 4. A horizontal groove 21 is opened on the outer side of the crossbar 2. A locking block 31 adapted to the horizontal groove 21 is opened on the inner side of the annular sleeve 3. The locking block 31 is slidably connected in the horizontal groove 21. A positioning component is provided between the annular sleeve 3 and the crossbar 2. Bolt holes 11 are provided at the four corners of the end fixing plate 1. Side frames 5 are fixed on both sides of the end fixing plate 1. A pair of guide rollers 51 are rotatably connected to each side frame 5. The connection position of the guide rollers 51 is aligned with the position of the slitting blade 41.

[0019] The positioning component includes a fixing hole 23 and an insertion rod 32. The fixing holes 23 are opened at the upper end of the crossbar 2 and are evenly distributed. The insertion rod 32 is slidably connected in the annular sleeve 3. The bottom of the insertion rod 32 is inserted into the corresponding fixing hole 23. The upper end of the insertion rod 32 extends out of the annular sleeve 3 and is fixed with an end plate 33. A fixing spring 34 is fixed between the end plate 33 and the annular sleeve 3. A positioning groove 22 is opened at the bottom of the horizontal groove 21. The width of the positioning groove 22 is adapted to the width of the locking block 31. The position of the positioning groove 22 is aligned with the position of the fixing hole 23. A scale line 24 is provided on the crossbar 2 above the horizontal groove 21.

[0020] Working principle: First, the end fixing plate 1 is fixed to the plastic wrap winding device by locking the locking bolt through the bolt hole 11. The plastic wrap is then passed between the guide rollers 51 to ensure that it can stably pass through the bottom of the blade holder 4 and be cut by the slitting blade 41. The width of the cut plastic wrap is the distance between the adjacent slitting blades 41. Therefore, when adjusting the width, the sliding of the annular sleeve 3 can be used to drive the slitting blade 41 to slide. In specific operation, the annular sleeve 3 is deflected at a certain angle, so that the locking block 31 slides from the positioning groove 22 into the horizontal groove 21. Since the locking block 31 can slide within the horizontal groove 21, the annular sleeve 3 can slide freely on the crossbar 2. After sliding to the designated position, the annular sleeve 3 can be rotated again, so that the locking block 31 is inserted into the positioning groove 22, preventing it from sliding horizontally. At this time, the position of the insertion rod 32 will be aligned with the position of the fixing hole 23. By using the fixing spring 34 to pull the end plate 33, the bottom of the insertion rod 32 can be inserted into the fixing hole 23, preventing the annular sleeve 3 from rotating, thereby achieving the purpose of fixing. The operation is simple and convenient, and the cutting width can be quickly adjusted without the need to disassemble or assemble the blade.
