Description

Technical Field

[0001] This utility model relates to the field of paper tube production technology, and in particular to a paper tube cutting device for paper drum production. Background Technology

[0002] Paper tubes are cylindrical packaging containers widely used in various industries such as food, pharmaceuticals, chemicals, textiles, and paper products. Based on their uses and characteristics, paper tubes can be classified into several types, including ordinary paper tubes, reinforced paper tubes, and flat-bottomed paper tubes. The paper tube manufacturing technology field mainly covers the processing and manufacturing process of paper tubes and related technologies. Within this field, paper tube cutting devices play a crucial role. These devices are specifically designed for cutting paper tubes, enabling them to precisely cut rolled paper or pre-formed paper tubes into the required specifications and dimensions.

[0003] Existing paper tube cutting devices used in paper drum production lack effective support and limiting for paper tubes of various sizes. Operators need to make frequent adjustments during use, which not only reduces the flexibility of the device but also easily causes the paper tube to shake during the cutting process, affecting cutting accuracy, reducing cutting efficiency, and increasing the labor intensity of operators. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing paper tube cutting devices mostly lack effective support and limiting for paper tubes of different specifications when in use, requiring frequent adjustments, reducing the flexibility of the device, easily causing the paper tube to shake, affecting the cutting accuracy and efficiency, and increasing the labor intensity of operators. Therefore, we propose a paper tube cutting device for paper drum production.

[0005] To achieve the above objectives, this application adopts the following technical solution: a paper tube cutting device for paper drum production, comprising a support base, mounting seats fixed on both sides of the top of the support base, rotating rollers slidably connected to both ends of the top of the mounting seats, a fixed shell fixed to one end of the rotating rollers, a rotating rod slidably connected inside the fixed shell, a circular plate fixed to one end of the rotating rod, a trapezoidal block fixed to the other end of the rotating rod, a movable plate fixed to the bottom of the trapezoidal block, a locking block fixed to the bottom of the movable plate, a plurality of locking grooves for cooperating with the locking blocks being opened inside the support base, a pull plate slidably connected to the surface of the rotating rod, a fixing block fixedly connected to both ends of the pull plate, and two fixing holes for cooperating with the fixing blocks being opened on both sides of the front end of the fixed shell.

[0006] Preferably, a first spring is slidably connected to the surface of the rotating rod, one end of the first spring is fixed to the circular plate, and the other end of the first spring is fixed to the pull plate.

[0007] Preferably, limit blocks are fixed on both sides inside the fixed shell, the limit blocks are located on both sides of the trapezoidal block, and the two sides of the limit blocks are slidably connected to one side of the trapezoidal block.

[0008] Preferably, sliders are fixed on both sides inside the fixed shell, and grooves that cooperate with the sliders are opened on both sides of the movable plate.

[0009] Preferably, a second spring is slidably connected to the surface of the card block, one end of the second spring is fixed to the moving plate, and the other end of the second spring is fixed to the inside of the fixed shell.

[0010] Preferably, the bottom of the support base has several collection holes, a fixed bucket is fixed to the bottom of the support base, a fixed frame is fixed to the bottom of the fixed bucket, and a collection box is slidably connected inside the fixed frame.

[0011] Preferably, a scraper is slidably connected inside the support base, an L-shaped plate is fixed to one end of the bottom of the scraper, a guide block is fixed to one end of the L-shaped plate, and a guide groove is provided at the front end of the support base to cooperate with the guide block.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by pulling the pull plate outward, the fixed block is driven away from the inside of the fixed hole. The moving rotating rod squeezes the trapezoidal block, causing the trapezoidal block to move. The trapezoidal block drives the moving plate to move towards the top of the fixed shell. During this process, the locking block will disengage from the inside of the locking groove, thereby releasing the fixation between the rotating roller and the support seat. At the same time, through the above process, the gap between the two rotating rollers can be adjusted according to different sizes of paper tubes, which plays a supporting and limiting role for the paper tube, improving the flexibility of the device, preventing the paper tube from shaking during cutting, improving cutting accuracy and cutting efficiency, and enhancing its stability.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 6 As shown, this utility model provides a technical solution: a paper tube cutting device for paper tube production, including a support base 1, mounting bases 2 fixed on both sides of the top of the support base 1, rotating rollers 3 slidably connected to both ends of the top of the mounting base 2, a fixed shell 6 fixed to one end of the rotating roller 3, a rotating rod 7 slidably connected inside the fixed shell 6, a circular plate 8 fixed to one end of the rotating rod 7, a trapezoidal block 9 fixed to the other end of the rotating rod 7, a movable plate 10 fixed to the bottom of the trapezoidal block 9, a locking block 11 fixed to the bottom of the movable plate 10, a plurality of locking grooves 12 for cooperating with the locking blocks 11 being opened inside the support base 1, a pull plate 13 slidably connected to the surface of the rotating rod 7, and fixed blocks 14 fixedly connected to both ends of the pull plate 13, and a fixed shell. Two fixing holes 15 are provided on both sides of the front end of the 6, which are used to cooperate with the fixing block 14. By pulling the pull plate 13 outward, the fixing block 14 is driven away from the inside of the fixing hole 15. The moving rotating rod 7 squeezes the trapezoidal block 9, which moves the trapezoidal block 9. The trapezoidal block 9 drives the moving plate 10 to move towards the top of the fixing shell 6. During this process, the locking block 11 will disengage from the inside of the locking groove 12, thereby releasing the fixation between the rotating roller 3 and the support seat 1. At the same time, through the above process, the gap between the two rotating rollers 3 can be adjusted according to the paper tube of different sizes, which plays a supporting and limiting role for the paper tube, improves the flexibility of the device, prevents the paper tube from shaking during cutting, improves the cutting accuracy and cutting efficiency, and enhances its stability.

[0023] Reference Figure 3As shown in this embodiment: a first spring 16 is slidably connected to the surface of the rotating rod 7. One end of the first spring 16 is fixed to the circular plate 8, and the other end of the first spring 16 is fixed to the pull plate 13. By setting the structure of the first spring 16, when the rotating rod 7 is released from fixation, the pull plate 13 is pulled at the same time as the rebound force of the first spring 16, which can easily drive the fixing block 14 out of the interior of the fixing hole 15, thereby releasing the fixation.

[0024] Reference Figure 4 As shown in this embodiment: Limiting blocks 17 are fixed on both sides inside the fixed shell 6. The limiting blocks 17 are located on both sides of the trapezoidal block 9. The two sides of the limiting blocks 17 are slidably connected to one side of the trapezoidal block 9. By setting the structure of the limiting blocks 17, the movement path of the trapezoidal block 9 is effectively constrained, preventing shaking and improving the stability of the device.

[0025] Reference Figure 4 As shown in this embodiment: sliders 18 are fixed on both sides inside the fixed shell 6, and grooves 19 that cooperate with the sliders 18 are opened on both sides of the moving plate 10. By setting the structure of sliders 18 and grooves 19, the moving plate 10 is prevented from deviating during movement, ensuring its smooth movement.

[0026] Reference Figure 4 As shown in this embodiment: a second spring 20 is slidably connected to the surface of the locking block 11. One end of the second spring 20 is fixed to the moving plate 10, and the other end of the second spring 20 is fixed to the inside of the fixed shell 6. By setting the structure of the second spring 20, when the fixing between the rotating roller 3 and the support seat 1 is released, the second spring 20 is in a stretched state. When it is necessary to fix the rotating roller 3 and the support seat 1, the rotating rod 7 is pulled to drive the trapezoidal block 9 to move towards the support seat 1. At the same time, with the action of the second spring 20, the moving plate 10 is pulled under the action of the two to drive the locking block 11 to be smoothly inserted into the inside of the locking slot 12.

[0027] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6As shown in this embodiment: several collection holes 21 are provided at the bottom of the support base 1, a fixed bucket 22 is fixed at the bottom of the support base 1, a fixed frame 23 is fixed at the bottom of the fixed bucket 22, a collection box 24 is slidably connected inside the fixed frame 23, a scraper 25 is slidably connected inside the support base 1, an L-shaped plate 27 is fixed at one end of the bottom of the scraper 25, a guide block 28 is fixed at one end of the L-shaped plate 27, and a guide groove 29 is provided at the front end of the support base 1 to cooperate with the guide block 28. By setting the structure of the collection holes 21 and the collection box 24, the debris generated during the cutting process can be collected directly, avoiding the accumulation of debris, thereby improving production efficiency and helping to reduce safety hazards caused by the scattering of debris. At the same time, the structure of the scraper 25 can move close to the surface of the support base 1 to scrape away debris and other impurities generated during the cutting process in a timely manner, ensuring the cleanliness of the support base 1.

[0028] Working principle: By pulling the pull plate 13 outward, the user moves the fixing block 14 away from the inside of the fixing hole 15. The moving rod 7 compresses the trapezoidal block 9, causing it to move. The trapezoidal block 9 then moves the moving plate 10 towards the top of the fixing shell 6. During this process, the locking block 11 disengages from the slot 12, thus releasing the fixation between the rotating roller 3 and the support base 1. Simultaneously, through this process, the gap between the two rotating rollers 3 can be adjusted according to different sizes of paper tubes, providing support and limiting for the paper tube, improving the flexibility of the device, preventing the paper tube from shaking during cutting, improving cutting accuracy and efficiency, and enhancing its stability. By setting the structure of the first spring 16, when the rotating rod 7 is released, pulling the pull plate 13, combined with the rebound force of the first spring 16, easily moves the fixing block 14 away from the inside of the fixing hole 15, achieving the release of the fixation. By setting the structure of the limiting block 17, the movement path of the trapezoidal block 9 is effectively constrained, preventing... The swaying mechanism improves the stability of the device. By setting the structure of slider 18 and slide groove 19, the moving plate 10 is prevented from deviating during movement, ensuring its smooth movement. By setting the structure of second spring 20, when the fixing between the rotating roller 3 and the support base 1 is released, the second spring 20 is in a stretched state. When it is necessary to fix the rotating roller 3 and the support base 1, the rotating rod 7 is pulled to drive the trapezoidal block 9 towards the support base 1. At the same time, with the action of the force of the second spring 20, the moving plate 10 is pulled and the locking block 11 is smoothly inserted into the slot 12. By setting the structure of collection hole 21 and collection box 24, the debris generated during the cutting process can be collected directly, avoiding the accumulation of debris, thereby improving production efficiency and helping to reduce the safety hazards caused by the scattering of debris. At the same time, the structure of scraper 25 can move close to the surface of support base 1 to scrape away debris and other impurities generated during the cutting process in time, ensuring the cleanliness of support base 1.
