Description

Technical Field

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

[0002] Paper winding machines are mainly used in paper processing production lines for operations such as paper winding and sheet winding. They are commonly found in industries such as paper production, printing, and packaging. Their function is to guide and adjust wide-width paper or paper rolls through rollers, with or without cutting, and then wind them into long, thin rolls to meet the needs of packaging or subsequent processing for different purposes.

[0003] Existing paper tube winding machines typically wind paper around a paper tube by attaching a paper tube to a winding roller and driving the roller with a motor. However, because the size of the winding roller is fixed, the inner diameter of the paper tube cannot be adjusted, limiting its applicability to tubes with a single inner diameter. When producing paper tubes with different inner diameters, corresponding winding rollers must be replaced. This process requires machine downtime and necessitates the use of multiple sets of winding rollers of different sizes, increasing costs and reducing efficiency.

[0004] Therefore, it is necessary to develop a tube winding machine for paper product processing to address the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a tube winding machine for paper product processing, which can be adapted to tube winding of paper products with different inner diameter specifications, thereby improving the applicability of the tube winding machine and increasing production efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model discloses a tube winding machine for paper product processing, comprising a base plate, a mounting plate vertically fixedly connected to one end of the base plate, a turntable rotatably connected to one side wall of the mounting plate, a housing fixedly connected to the side wall of the turntable away from the mounting plate, three sliders slidably connected to the side wall of the housing away from the mounting plate, and a horizontally arranged tube winding shaft fixedly connected to one end of the top surface of each slider near the center of the housing; an adjustment assembly is provided inside the housing for adjusting the three sliders to synchronously move closer to or away from the center of the housing; a drive assembly is provided on the base plate for driving the turntable to rotate.

[0007] Furthermore, the adjusting component includes a large bevel gear, which is rotatably connected inside the housing. A flat threaded disc is fixedly connected to the side wall of the large bevel gear near the slider. The flat threaded disc has a flat thread. The bottom surface of the slider has a threaded groove that meshes with the flat threaded disc. Three small bevel gears are evenly distributed on the housing and are rotatably connected to the housing. All three small bevel gears mesh with the large bevel gear.

[0008] Furthermore, an adjusting rod is fixedly connected to the outer end of the small bevel gear, the outer end of the adjusting rod penetrates the outer shell, and an adjusting hole is opened on the outer end face of the adjusting rod, the adjusting hole being a rectangular hole.

[0009] Furthermore, three spaced grooves are provided on the side wall of the outer casing away from the mounting plate. The grooves are arranged from the circumference of the outer casing toward its center, and the slider is slidably connected in the grooves.

[0010] Furthermore, guide rails are fixedly connected to the inner walls of both ends of the slide along its length, and grooves that slide and engage with the guide rails are provided on the two side walls of the slider.

[0011] Furthermore, a scale line is provided on the side wall of the outer shell on one side of the slider. The scale line is parallel to the slider's movement direction. An indicator strip is fixedly connected to the top surface of the slider. The indicator strip is perpendicular to the slider's movement direction and is tangent to the outer wall of the winding tube shaft away from the center of the outer shell.

[0012] Furthermore, the drive assembly includes a motor, which is fixedly mounted on the top surface of the base plate. A rotating shaft is fixedly connected to the side wall of the turntable, and the rotating shaft is rotatably connected to the mounting plate. The output end of the motor is coaxially and fixedly connected to the rotating shaft.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This invention, by incorporating an adjustment component, can drive three sliders to synchronously move closer to or further away from the center of the outer casing. This, in turn, causes the winding shafts fixedly connected to the sliders to move synchronously, enabling flexible adjustment of the inner diameter of the roll enclosed by the three winding shafts. This allows for the processing of paper tubes with different inner diameters, improving the applicability of the device. Furthermore, this invention allows for adjustment of the roll's inner diameter without requiring machine downtime to replace components such as the take-up roller, reducing production interruptions and labor costs, and improving overall production efficiency.

Detailed Implementation

[0017] The core of this utility model is to provide a tube winding machine for paper product processing, which can be adapted to tube winding of paper products with different inner diameter specifications, thereby improving the applicability of the tube winding machine and increasing production efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In one specific embodiment of this utility model, such as Figure 1 and Figure 2As shown, the system includes a base plate 1, with a mounting plate 2 vertically fixed to one end of the base plate 1. A turntable 3 is rotatably connected to one side wall of the mounting plate 2. A housing 4 is fixedly connected to the side wall of the turntable 3 away from the mounting plate 2. Three sliders 5 are slidably connected to the side wall of the housing 4 away from the mounting plate 2. A horizontally positioned roller shaft 6 is fixedly connected to one end of the top surface of each slider 5 near the center of the housing 4. An adjustment assembly is provided inside the housing 4 to adjust the position of the three sliders 5 synchronously moving closer to or further away from the center of the housing 4. A drive assembly is provided on the base plate 1 to drive the turntable 3 to rotate.

[0021] By adjusting the component, the three sliders 5 are driven to move synchronously closer to or further away from the center of the outer shell 4, which in turn drives the winding shaft 6 to change the circumferential diameter, thereby adjusting the inner diameter of the paper tube. The drive component drives the turntable 3, the outer shell 4 and the winding shaft 6 to rotate synchronously, and the paper product is wound on the three winding shafts 6 to complete the winding of the paper product.

[0022] In one specific embodiment of this utility model, such as Figures 3-5 As shown, the adjusting assembly includes a large bevel gear 7, which is rotatably connected inside the housing 4. A flat threaded disc 8 is fixedly connected to the side wall of the large bevel gear 7 near the slider 5. The flat threaded disc 8 has a flat thread, and the bottom surface of the slider 5 has a threaded groove 9 that meshes with the flat threaded disc 8. Three small bevel gears 10 are evenly distributed on the housing 4 and are rotatably connected to the housing 4. All three small bevel gears 10 mesh with the large bevel gear 7.

[0023] Rotating any one of the small bevel gears 10 can drive the large bevel gear 7 to rotate, which in turn drives the planar threaded disc 8 to rotate synchronously. The planar thread engages with the threaded groove 9 of the slider 5, converting the rotational motion into linear motion of the slider 5 along the radial direction of the outer shell 4. Since all three sliders 5 engage with the planar thread simultaneously, they move synchronously, ensuring that the circumference diameter of the coiled tube shaft 6 changes uniformly.

[0024] Specifically, an adjusting rod 11 is fixedly connected to the outer end of the small bevel gear 10. The outer end of the adjusting rod 11 passes through the outer shell 4, and an adjusting hole 12 is opened on the outer end face of the adjusting rod 11. The adjusting hole 12 is a rectangular hole.

[0025] By inserting a tool into the adjustment hole 12 and rotating the adjustment rod 11, the small bevel gear 10 is rotated, which in turn drives the large bevel gear 7 and the flat threaded disc 8, thereby adjusting the position of the slider 5 and the coil shaft 6. Any one of the three adjustment rods 11 can be operated, allowing operators to adjust from different angles and improving ease of operation.

[0026] In one specific embodiment of this utility model, such as Figure 4 and Figure 5 As shown, three spaced grooves 13 are provided on the side wall of the outer casing 4 away from the mounting plate 2. The grooves 13 are set from the circumference of the outer casing 4 toward its center, and the slider 5 is slidably connected in the grooves 13.

[0027] The slide groove 13 provides a guide for the radial movement of the slider 5, ensuring that the slider 5 always moves along the radial direction of the outer shell 4, avoiding the positional deviation of the winding tube shaft 6 due to the meshing deviation of the planar thread, ensuring the coaxiality of the axes of the three winding tube shafts 6, and improving the roundness accuracy of the paper tube winding.

[0028] Specifically, guide rails 14 are fixedly connected to the inner walls of both ends of the slide groove 13 along its length, and grooves 15 are provided on both sides of the slider 5 to slide and engage with the guide rails 14. The engagement between the guide rails 14 and the grooves 15 further restricts the degree of freedom of movement of the slider 5, preventing the slider 5 from moving up and down or flipping during sliding, and ensuring that the slider 5 moves smoothly.

[0029] In one specific embodiment of this utility model, such as Figure 4 and Figure 5 As shown, a scale line 16 is provided on the side wall of the outer shell 4 on one side of the slider 5. The scale line 16 is set parallel to the moving direction of the slider 5. An indicator strip 17 is fixedly connected to the top surface of the slider 5. The indicator strip 17 is perpendicular to the moving direction of the slider 5 and is tangent to the outer wall of the winding tube shaft 6 away from the center of the outer shell 4.

[0030] By using the scale line 16 indicated by the indicator bar 17, staff can intuitively read the inner diameter radius of the paper tube formed by the three winding shafts 6, and quickly adjust it to the target size without the need for additional measuring tools, thus improving adjustment efficiency and accuracy.

[0031] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the drive assembly includes a motor 18, specifically a geared motor. The motor 18 is fixedly mounted on the top surface of the base plate 1. A rotating shaft 19 is fixedly connected to the side wall of the turntable 3, and the rotating shaft 19 is rotatably connected to the mounting plate 2. The output end of the motor 18 is coaxially and fixedly connected to the rotating shaft 19. When the motor 18 is started, it drives the turntable 3, the outer shell 4, the slider 5, and the winding tube shaft 6 to rotate synchronously via the rotating shaft 19.

[0032] Working principle of this utility model: When using the paper tube winding machine of this utility model, insert a wrench into the adjustment hole 12 of any one of the adjustment rods 11, and rotate the adjustment rod 11 clockwise. This drives the small bevel gear 10 to rotate, which in turn drives the large bevel gear 7 to rotate synchronously with the flat threaded disc 8. The flat threaded disc engages with the threaded groove 9 of the slider 5, pushing the three sliders synchronously away from the center of the outer shell 4 along the groove 13, thus increasing the circumference diameter formed by the winding shaft 6. Observe the scale line 16 pointed to by the indicator bar 17. When the radius value of the target paper tube inner diameter is reached, stop rotating the adjustment rod 11 to complete the inner diameter adjustment. If it is necessary to reduce the inner diameter, simply rotate the adjustment rod 11 counterclockwise. Fix the starting end of the paper product on the outside of the circumference formed by the three winding shafts 6, ensuring that the paper product is flat and fits snugly against the winding shafts 6. Start the motor 18, which drives the turntable 3, the outer shell 4, and the winding shafts 6 to rotate synchronously through the rotating shaft 19. The paper product is gradually wound around the outside of the winding shafts 6 to form a paper tube.
