Description

Technical Field

[0001] This utility model relates to the field of stretch film paper tube processing technology, and in particular to a stretch film paper tube cutting machine. Background Technology

[0002] When selling stretch film, it is wound onto paper tubes for convenient use. Therefore, while producing a large quantity of stretch film, a large quantity of paper tubes is also required. Depending on the required specifications, the paper tube raw materials also need to be divided into multiple finished paper tubes at equal intervals.

[0003] In existing technologies, when dividing paper tube raw materials into equal intervals, the paper tube raw materials are first placed at the cutting station, and then the cutting mechanism divides the paper tube raw materials. After the division is completed, multiple finished paper tubes and waste materials are removed from the cutting station, and then the paper tube raw materials are placed back.

[0004] Although the above method can produce finished paper tubes, the time interval between two adjacent dividing operations is relatively long due to the sequence of feeding, dividing, and unloading, and the production efficiency still needs to be improved.

[0005] Therefore, it is necessary to invent a paper tube cutting machine for stretch film to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a paper tube cutting machine for stretch film, which can simultaneously perform the feeding and unloading operations of paper tube raw materials during the cutting process, thereby effectively shortening the time interval between two adjacent cutting operations and significantly improving production efficiency. This solves the problem mentioned in the background art that the long interval between two adjacent cutting operations due to the sequential order of feeding, cutting and unloading, and the need to improve production efficiency, is still a problem.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a wrapping film tube cutting machine, comprising:

[0008] A bearing and positioning mechanism is provided to provide an installation base for the dividing mechanism and the synchronous loading and unloading mechanism.

[0009] A dividing mechanism, wherein the dividing mechanism is used to divide the paper tube raw material at equal intervals; and

[0010] The synchronous loading and unloading mechanism includes a rotating disk that is rotatably sleeved on the outside of the mounting column via a bearing. Multiple positioning magnets B are uniformly and fixedly nested on the top edge of the rotating disk. Multiple positioning slots are uniformly opened on the top of the rotating disk. Multiple clearance slots are opened inside any one of the positioning slots. Multiple fixing plates are uniformly and fixedly installed on the top of the rotating disk. Locking bolts are threadedly connected to the inner side of the fixing plates. Locking plates that are slidably installed inside adjacent positioning slots are rotatably sleeved on the inner end of the locking bolts via a bearing.

[0011] According to at least one embodiment of the present disclosure, the wrapping film tube cutting machine includes a support platform, and a support base is fixedly disposed at the bottom of the support platform.

[0012] According to at least one embodiment of the present disclosure, a paper tube cutting machine for wrapping film is provided with a mounting column fixedly disposed at the top center of the support platform, and a positioning magnet A is fixedly nested on the front side of the top of the support platform, which magnetically attracts the adjacent positioning magnet B.

[0013] According to at least one embodiment of the present disclosure, the stretch film tube cutting machine includes a fixing frame fixedly disposed on the rear side of the top of the support platform and fixedly connected to the top of the mounting column. An electric push rod is fixedly disposed on the top of the fixing frame, and the output shaft of the electric push rod extends to the bottom of the fixing frame and is fixedly connected to a lifting plate.

[0014] According to at least one embodiment of the present disclosure, a paper tube cutting machine for stretch film is provided with guide rods that slide through the fixed frame in a vertical direction on both sides of the top of the lifting plate, and a plurality of mounting plates are uniformly fixed at the bottom of the lifting plate.

[0015] According to at least one embodiment of the present disclosure, a paper tube cutting machine for stretch film is provided with a motor fixedly mounted on one side of any of the mounting plates. The output shaft of the motor extends to the other side of the mounting plate and is fixedly connected to a cutting blade. Each of the cutting blades is located directly above an adjacent clearance groove and the distance between two adjacent cutting blades is equal.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a synchronous loading and unloading mechanism. During the process of the paper tube material being divided by the dividing mechanism inside the rear positioning groove, the divided paper tube material inside the front positioning groove is removed, and then the paper tube material is repositioned. The front locking bolt is then rotated, causing the locking plate to move backward within the front positioning groove, thus clamping and fixing the paper tube material against the inner wall of the front positioning groove. After the paper tube material inside the rear positioning groove is divided, the rotating disk is rotated clockwise, bringing the paper tube material to be divided closer to the dividing station. Simultaneously, the divided paper tube material is moved out by the dividing station. Compared to existing technologies, this invention allows for simultaneous loading and unloading of paper tube material during the dividing process, effectively shortening the time interval between adjacent dividing operations and significantly improving production efficiency.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0028] Figure 2 This is a schematic diagram of the bearing and positioning mechanism 1 and the dividing mechanism 2 of a stretch film tube cutting machine according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the synchronous loading and unloading mechanism 3 of a wrapping film tube cutting machine according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the stretch film tube cutting machine disclosed herein may include components such as a bearing and positioning mechanism 1, a dividing mechanism 2, and a synchronous loading and unloading mechanism 3.

[0031] like Figure 2 As shown in this disclosure, the bearing positioning mechanism 1 includes a bearing platform 11, which is made of Q235 low carbon steel. It has high strength and can stably bear the weight of the dividing mechanism 2 and the synchronous loading and unloading mechanism 3. A support base 12 is fixedly installed at the bottom of the bearing platform 11. The support base 12 is made of the same material as the bearing platform 11 and has a rubber pad bonded to the bottom to reduce vibration and noise during equipment operation. A mounting column 13 is fixedly installed at the center of the top of the bearing platform 11. The surface is chrome-plated to improve wear resistance and rust prevention and prevent rusting from long-term contact with air. A positioning magnet A14 is fixedly nested on the front side of the top of the bearing platform 11. The positioning magnet A14 is magnetically attracted to the adjacent positioning magnet B32. It is made of neodymium iron boron permanent magnet, which has strong magnetism and can form a firm magnetic attraction with the positioning magnet B32.

[0032] This allows the support base 12 to support the support platform 11, the support platform 11 to install the support base 12, and the mounting column 13 to install the rotating disk 31.

[0033] like Figure 2 As shown, in a preferred embodiment, the dividing mechanism 2 includes a fixed frame 21 fixedly disposed on the rear side of the top of the support platform 11 and fixedly connected to the top of the mounting column 13. The frame is made of 6061 aluminum alloy, is lightweight, has good rigidity, and is anodized, making it rust-proof, oil-resistant, and easy to clean. An electric push rod 22 is fixedly disposed on the top of the fixed frame 21. The output shaft of the electric push rod 22 extends to the bottom of the fixed frame 21 and is fixedly connected to a lifting plate 23. Guide rods 24, made of 45# steel and slidably penetrating the fixed frame 21, are fixedly disposed on both sides of the top of the lifting plate 23. The bottom of the lifting plate 23 is uniformly fixed with multiple mounting plates 25. A motor 26 is fixedly mounted on one side of any mounting plate 25. The motor is a three-phase asynchronous motor, which is energy-saving and has stable power to meet the rotation requirements of the cutting blade 27. The output shaft of the motor 26 extends to the other side of the mounting plate 25 and is fixedly connected to the cutting blade 27, which is made of high-speed steel. It has high sharpness and is suitable for cutting paper materials. It is moderately priced and can be sharpened and reused multiple times, making it suitable for small and medium batch production. Any cutting blade 27 is located directly above the adjacent clearance groove 34 and the distance between two adjacent cutting blades 27 is equal.

[0034] Therefore, the electric push rod 22 drives the lifting plate 23, which is guided by the guide rod 24, to move continuously downward. When the lifting plate 23 moves downward, it drives multiple cutting blades 27 to move downward synchronously through multiple mounting plates 25. During this process, the motor 26 drives the cutting blades 27 to rotate continuously. As the cutting blades 27 move downward continuously, the multiple cutting blades 27 cooperate with each other to divide the paper tube material at equal intervals. After the division is completed, the electric push rod 22 drives the lifting plate 23 to move upward and reset.

[0035] like Figure 3 As shown in this disclosure, the synchronous loading and unloading mechanism 3 includes a rotating disk 31 mounted on the outside of the mounting column 13 via a bearing. The disk is made of 6061 aluminum alloy, making it lightweight and with low rotational resistance. Multiple positioning magnets B32 are uniformly and fixedly nested on the top edge of the rotating disk 31. These magnets are made of the same material as the positioning magnets A14 to ensure consistent magnetic attraction strength and prevent positioning deviations due to differences in magnet performance. Multiple positioning grooves 33 are uniformly opened on the top of the rotating disk 31. Multiple clearance grooves 34 are opened inside any one of the positioning grooves 33, integrally formed with the rotating disk 31 to ensure coaxiality between the grooves and the rotating disk 31. Additionally, when there are excessive cutting debris inside the positioning grooves 33 and clearance grooves 34, a blower can be used to clean the debris. Multiple fixing plates 35 are uniformly fixed on the top of the rotating disk 31. Locking bolts 36 are threaded onto the inner side of the fixing plates 35. Locking plates 37, which are slidably mounted inside adjacent positioning grooves 33, are mounted on the inner end of the locking bolts 36 via a bearing.

[0036] Therefore, during the process of the paper tube material inside the rear positioning groove 33 being divided by the dividing mechanism 2, the paper tube material divided inside the front positioning groove 33 is taken out, and then the paper tube material is placed back in. Then the front locking bolt 36 is rotated, which causes the locking bolt 36 to drive the locking plate 37 to move backward continuously inside the front positioning groove 33, thereby clamping and fixing the paper tube material with the inner wall of the front positioning groove 33. After the paper tube material inside the rear positioning groove 33 is divided, the rotating disk 31 is rotated clockwise, thereby moving the paper tube material to be divided towards the dividing mechanism. As the positions of the materials are close together, the paper tubes after being cut are moved out by the cutting operator. During this process, when any positioning magnet B32 moves to a position adjacent to positioning magnet A14, positioning magnet A14 and the adjacent positioning magnet B32 are magnetically attracted, thereby positioning the rotating disk 31 and ensuring the accuracy of subsequent cutting. The clearance groove 34 can avoid the cutting blade 27 during the cutting process. Compared with the existing technology, the feeding and unloading operations of paper tube materials can be carried out simultaneously during the cutting process, thereby effectively shortening the time interval between two adjacent cutting operations and significantly improving production efficiency.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
