Description

Technical Field

[0001] This utility model relates to the technical field of paper roll production, specifically a waste collection mechanism for paper roll production. Background Technology

[0002] In the household paper industry, toilet paper is a daily necessity for households and public places, with huge market demand. As consumers' requirements for toilet paper quality continue to increase and market competition intensifies, toilet paper manufacturers need to continuously optimize production processes and improve production efficiency and product quality. In the toilet paper production process, the cutting process is the key step in processing large rolls of raw paper into finished toilet paper rolls that meet specifications.

[0003] Existing conveyor systems for paper roll production cutting are widely used on paper roll production lines. These systems mainly consist of a conveyor belt, a drive unit, and a support structure. In the paper roll production process, after the paper roll is cut into finished products, the finished rolls are placed onto the conveyor belt as the cutting components swing. Driven by the drive unit, the conveyor belt transports the finished rolls to the paper roll processing table. During this transport, a limiting plate positioned above the conveyor belt protects the rolls from falling to the sides. At the processing table, workers perform subsequent packaging and other operations on the rolls, transforming them into marketable products. However, this type of conveyor system lacks a dedicated and comprehensive collection method for waste edges generated during the cutting process; it simply relies on the conveyor belt to remove them from the cutting area.

[0004] Existing conveyor systems in paper roll production cutting mechanisms have significant shortcomings in waste edge handling. In actual use, waste edges generated during cutting often come into contact with the limiting plate above the conveyor belt, causing them to remain on the belt and begin to rotate with its movement. These waste edges cannot automatically detach, and their residue on the conveyor belt easily comes into contact with subsequently transported finished paper rolls. This can not only scratch the surface of the paper rolls, affecting their appearance quality, but also cause jamming during transport, affecting the smoothness of the conveyor. Even if the waste edges do not remain on the conveyor belt, they will still be transported to the paper roll processing table and mixed with the cut finished paper rolls. This requires workers to spend extra time and effort to separate the waste edges from the finished paper rolls before subsequent packaging, increasing labor costs and intensity, and reducing production efficiency, failing to meet the needs of paper roll manufacturers for efficient and low-cost production. Therefore, developing an efficient waste edge collection mechanism for paper roll production is crucial. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a waste collection mechanism for paper roll production, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste collection mechanism for paper roll production, comprising a conveyor frame and a conveyor belt, wherein a limit plate is slidably installed on the outer wall of the conveyor frame, and an adjustment mechanism corresponding to the limit plate is installed on the outer wall of the conveyor frame;

[0007] The conveyor belt has multiple sets of waste drop troughs for waste to fall off the conveyor belt, and a waste guide plate is provided between the top and bottom surfaces of the conveyor belt to guide the waste, and the waste guide plate is located below the waste drop troughs on the top surface of the conveyor belt.

[0008] The conveyor belt is detachably equipped with an external plate corresponding to the position of the waste trough, which is used to adjust the opening size of the waste trough. A pressure roller is rotatably mounted on the bottom of the limiting plate above the conveyor belt, and the pressure roller is in contact with the conveyor belt. During the operation of the conveyor belt, the pressure roller will intermittently squeeze the external plate to ensure that the external plate can be stably installed on the conveyor belt.

[0009] By adopting the above technical solution, the conveyor frame, conveyor belt, limiting plate, adjustment mechanism, waste trough, waste guide plate, external connecting plate and pressure roller work together to solve the problem that the traditional conveying device does not have a special waste collection measure, which leads to waste residue on the edge of the paper roll and mixing with the finished product.

[0010] Furthermore, the adjustment mechanism includes two sets of connecting frames connected to the limiting plate and two sets of bidirectional screws threadedly connected to the two sets of connecting frames, as well as two sets of mounting seats rotatably connected to the ends of the bidirectional screws, and the mounting seats are connected to the conveyor frame.

[0011] By adopting the above technical solution, the distance between the two sets of limiting plates can be quickly adjusted without disassembling or replacing parts, thus adapting to rolls of paper of different widths and avoiding the trouble of reinstalling the limiting plates due to changes in the width of the rolls of paper.

[0012] Furthermore, the length of the waste trough is greater than the width of the waste material edge and less than the length of the paper roll, and the length of the waste trough is greater than the diameter of the paper roll.

[0013] By adopting the above technical solution, it is possible to ensure that the waste edges generated during cutting can fall smoothly from the waste chute, and to prevent the finished paper rolls from slipping from the waste chute during the conveying process, thus avoiding losses. It can accurately distinguish between waste edges and finished paper rolls, eliminating the need for subsequent manual sorting and separation, reducing finished product waste and labor costs, and ensuring the economy and efficiency of paper roll production.

[0014] Furthermore, the outer wall of the conveyor frame is symmetrically provided with waste discharge grooves corresponding to the waste guide plate, and the cross-section of the waste guide plate is designed in an inverted V shape.

[0015] By adopting the above technical solution, the waste material falling from the waste chute can be caught by the waste guide plate, and the inverted V-shaped structure guides the waste material to slide to both sides and finally be discharged through the waste discharge chute, avoiding the accumulation and blockage of waste material inside the conveyor belt and ensuring the continuous and smooth operation of the conveyor belt.

[0016] Furthermore, the conveyor belt has an installation groove corresponding to the external connector and communicating with the waste trough, and a positioning post that is slidably connected to the external connector is installed in the installation groove, and after the external connector is installed in the installation groove, its outer wall does not protrude from the outer wall of the conveyor belt.

[0017] By adopting the above technical solution, the external piece can be slidably installed into the installation groove along the positioning post, so as to realize the adjustment of the opening size of the waste trough to adapt to the edge of waste material of different widths.

[0018] Furthermore, multiple sets of connecting strips are installed at equal intervals on the outer wall of the outer connecting piece, and a positioning block is installed at the outer end of each connecting strip. The diameter of the positioning block is larger than the width of the connecting strip, and multiple sets of connecting grooves corresponding to the connecting strips and positioning blocks are opened on the conveyor belt.

[0019] By adopting the above technical solution, the connecting strip and the positioning block are embedded in the connecting groove, which increases the contact area and connection stability between the outer piece and the conveyor belt. In addition, the diameter of the positioning block is larger than the width of the connecting strip, which can prevent the connecting strip from coming out of the connecting groove. Combined with the elastic properties of the rubber material, the installation of the outer piece is more secure.

[0020] Furthermore, the outer plate, connecting strip, and positioning block are all made of rubber. When the conveyor belt is running, the bottom surface of the pressure roller will squeeze the two sides of the outer plate, the connecting strip, and the positioning block. The outer wall of the limiting plate is rotatably equipped with a support wheel that is in contact with the top of the pressure roller.

[0021] By adopting the above technical solution, the gap between the pressure rollers squeezes the outer connecting piece, connecting strip and positioning block when the conveyor belt is running, further reinforcing the installation of the outer connecting piece.

[0022] In summary, the present invention has the following main advantages:

[0023] This invention features multiple waste collection troughs installed on a conveyor belt and waste guide plates mounted on a conveyor frame, enabling automatic separation and collection of waste edges. Furthermore, the external connecting plates allow for adjustment of the waste collection trough openings to accommodate waste edges of varying thicknesses, while the adjustment mechanism adjusts the spacing of the limiting plates to accommodate different roll paper specifications. The pressure rollers and support rollers work together to ensure stable installation of the external connecting plates. The entire process eliminates the need for manual separation of waste edges, preventing waste edges from scratching the roll paper or mixing with the finished product. This improves the quality of roll paper production, reduces labor costs, increases production efficiency, and meets the needs of mass production of roll paper. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] A waste collection mechanism for paper roll production, such as Figure 1 - Figure 6 As shown, it includes components such as a conveyor frame 1, a conveyor belt 2, a limiting plate 3, an adjusting mechanism 4, a waste guide plate 6, an external connecting plate 8, a pressure roller 13, and a support roller 14;

[0034] Among them, the conveyor frame 1 is the basic support frame of the mechanism, which is used to install components such as the conveyor belt 2 and the limiting plate 3 to ensure the stability of the overall structure; while the conveyor belt 2 is installed on the conveyor frame 1 to convey the roll paper and separate the waste material edge. A waste guide plate 6 is provided between its top and bottom surfaces. The waste guide plate 6 is located below the waste drop trough 5 on the top surface of the conveyor belt 2 to guide the waste material edge falling from the waste drop trough 5.

[0035] Secondly, multiple sets of waste drop troughs 5 are provided on the conveyor belt 2. The waste drop troughs 5 are used for the waste material edge to fall off the conveyor belt 2. The length of the waste material edge is greater than the width of the waste material edge and less than the length of the roll paper. The length of the waste drop trough 5 is greater than the diameter of the roll paper. This ensures that the waste material edge can fall off smoothly and prevents the roll paper from slipping off the waste drop trough 5, thus avoiding finished product loss.

[0036] Specifically, a limiting plate 3 is slidably installed on the outer wall of the conveyor frame 1. The limiting plate 3 is used to limit the conveying trajectory of the paper roll and prevent the paper roll from falling to both sides. At the same time, an adjustment mechanism 4 corresponding to the limiting plate 3 is installed on the outer wall of the conveyor frame 1. The adjustment mechanism 4 is used to adjust the distance between the two sets of limiting plates 3 to adapt to paper rolls of different widths.

[0037] The adjustment mechanism 4 in this embodiment specifically includes two sets of connecting frames connected to the limiting plate 3, a bidirectional screw threaded to the two sets of connecting frames, and two sets of mounting seats rotatably connected to the ends of the bidirectional screws. The mounting seats are connected to the conveying frame 1. By rotating the bidirectional screws, the two sets of connecting frames can be driven to slide relative to the limiting plate 3, thereby achieving rapid adjustment of the spacing.

[0038] For example, symmetrical waste discharge grooves corresponding to the waste guide plate 6 are provided on the outer wall of the conveyor frame 1. The waste guide plate 6 has an inverted V-shaped cross section. The inverted V-shaped structure can guide the waste material to slide to both sides and finally be discharged through the waste discharge groove, thus avoiding the accumulation of waste material inside the conveyor belt 2. The position of the waste guide plate 6 is precisely corresponding to the waste drop chute 5, ensuring that the waste material falling from the waste drop chute 5 can be completely caught.

[0039] In this embodiment, an external connecting piece 8 is detachably installed on the conveyor belt 2. The external connecting piece 8 corresponds to the position of the waste trough 5 and is used to adjust the opening size of the waste trough 5 to accommodate waste material edges of different widths.

[0040] Meanwhile, an installation groove 7 corresponding to the outer connecting piece 8 and communicating with the waste trough 5 is provided on the conveyor belt 2. A positioning post 9 is installed in the installation groove 7, and a positioning hole is provided through the outer connecting piece 8. The positioning post 9 is slidably connected to the outer connecting piece 8 through the positioning hole for preliminary positioning of the outer connecting piece 8. After the outer connecting piece 8 is installed in the installation groove 7, its outer wall does not protrude from the outer wall of the conveyor belt 2 to avoid affecting the stability of the paper roll conveying.

[0041] For example, in this embodiment, multiple sets of connecting strips 10 are installed at equal intervals on the outer wall of the outer connecting piece 8. Each connecting strip 10 has a positioning block 11 installed at its outer end. The diameter of the positioning block 11 is larger than the width of the connecting strip 10. At the same time, multiple sets of connecting grooves 12 corresponding to the connecting strips 10 and the positioning blocks 11 are opened on the conveyor belt 2. The connecting strips 10 and the positioning blocks 11 are embedded in the connecting grooves 12, which can enhance the connection stability between the outer connecting piece 8 and the conveyor belt 2.

[0042] It should be noted that the outer piece 8, connecting strip 10 and positioning block 11 in this embodiment are all made of rubber. Rubber is elastic, which makes it easy to install and disassemble, and it can fit tightly into the connecting groove 12 after being squeezed, thus improving the fixing effect.

[0043] For example, a pressure roller 13 is provided above the conveyor belt 2. The pressure roller 13 is rotatably installed at the bottom of the limiting plate 3 and is in contact with the conveyor belt 2. During the operation of the conveyor belt 2, the pressure roller 13 will intermittently squeeze the two sides of the outer piece 8, the connecting strip 10 and the positioning block 11 to further reinforce the installation of the outer piece 8 and prevent it from shifting with the conveyor belt 2.

[0044] Meanwhile, a support wheel 14 is rotatably installed on the outer wall of the limiting plate 3. The support wheel 14 is in contact with the top of the pressure wheel 13 to restrict the outer end of the pressure wheel 13, prevent the pressure wheel 13 from tilting upward due to the squeezing force, and ensure that the pressure wheel 13 is always in contact with the conveyor belt 2.

[0045] Through the coordinated operation of the above components, during use, the spacing of the limiting plates 3 is first adjusted by the adjusting mechanism 4 to match the width of the roll paper. Then, the corresponding external connecting piece 8 is selected according to the width of the waste edge and installed on the conveyor belt 2, and the opening of the waste drop trough 5 is adjusted. When the conveyor belt 2 is running, the roll paper is conveyed along the space between the limiting plates 3, and the waste edge falls from the waste drop trough 5 to the waste guide plate 6, and is guided by the waste guide plate 6 to be discharged from the waste discharge trough. The gap of the pressure roller 13 squeezes the external connecting piece 8 to ensure its stability, and the support roller 14 ensures that the pressure roller 13 is in contact with the surface. The entire process realizes automatic separation and collection of waste edge, avoiding mixing with the finished roll paper, and improving production efficiency and roll paper quality.

[0046] The working principle of this utility model is as follows: First, the position of the limiting plate 3 is adjusted by the adjusting mechanism 4. By rotating the bidirectional screw of the adjusting mechanism 4, the bidirectional screw is threadedly connected to the connecting frame of the limiting plate 3. The rotation of the bidirectional screw drives the two sets of connecting frames and the two sets of limiting plates 3 to slide relative to each other along the conveying frame 1 until the distance between the two sets of limiting plates 3 is adapted to the width of the roll paper. This can prevent the roll paper from falling to both sides during conveying and also reserve a channel for the waste material to fall off.

[0047] Next, adjust the opening size of the waste trough 5 according to the width of the waste edge; specifically, align the corresponding length of the outer connecting piece 8 with the mounting groove 7 of the conveyor belt 2, so that the positioning hole of the outer connecting piece 8 is aligned with the positioning post 9 in the mounting groove 7, and push the outer connecting piece 8 into the mounting groove 7; at the same time, the outer connecting piece 8, its outer wall connecting strip 10, and the positioning block 11 at the end are all made of rubber. Embed the positioning block 11 and the connecting strip 10 into the connecting groove 12 of the conveyor belt 2. Through the double positioning of the positioning post 9 and the connecting groove 12, the outer connecting piece 8 is fixed. After installation, the outer connecting piece 8 does not protrude from the outer wall of the conveyor belt 2 to avoid affecting the paper roll conveying; at this time, the actual opening width of the waste trough 5 is formed by the outer connecting piece 8 blocking it, ensuring that the opening only allows the waste edge to pass through. The length of the waste trough 5 is greater than the width of the waste edge and less than the length and diameter of the paper roll to prevent the paper roll from falling from the waste trough 5;

[0048] After the mechanism is started, the conveyor belt 2 operates under the drive of the drive device, and the roll of paper is transported onto the conveyor belt 2 and smoothly transmitted along the channel between the two sets of limiting plates 3; the pressure roller 13 is in contact with the top surface of the conveyor belt 2, and the conveyor belt 2 drives the pressure roller 13 to rotate synchronously; during the rotation of the pressure roller 13, it intermittently squeezes the two sides of the outer piece 8, the connecting strip 10 and the positioning block 11. The rubber material is elastic, and after squeezing, it fits more tightly with the mounting groove 7 and the connecting groove 12, further strengthening the installation stability of the outer piece 8 and preventing the outer piece 8 from shifting when the conveyor belt 2 is running; at the same time, the support wheel 14 on the outer wall of the limiting plate 3 is in contact with the top of the pressure roller 13 to prevent the pressure roller 13 from tilting upward due to the squeezing force, and to ensure that the pressure roller 13 is always in contact with the conveyor belt 2;

[0049] During the conveying process of the paper roll, the waste edges generated by cutting move synchronously with the paper roll. Since the opening of the waste trough 5 is only suitable for the width of the waste edge, the waste edge falls from the waste trough 5 into the inside of the conveyor belt 2. The waste guide plate 6 between the top and bottom surfaces of the conveyor belt 2 is located below the waste trough 5 to catch the falling waste edge. The inverted V-shaped structure guides the waste edge to slide to both sides and finally discharges it through the waste discharge trough on the outer wall of the conveyor frame 1, thus completing the automatic collection of the waste edge and preventing the waste edge from remaining on the conveyor belt 2.

[0050] If you need to change to a different specification of paper roll or adjust the width of the waste edge collection, simply reverse the operation. First, stop the conveyor belt 2, manually peel off the outer connecting piece 8, replace it with a different size outer connecting piece 8, and then reinstall it. Then, adjust the spacing of the limit plate 3 through the adjustment mechanism 4 to adapt to the new production requirements. The whole process requires no complicated tools, is easy to operate, and achieves automatic separation and collection of waste edges throughout the process, avoiding the waste edges from mixing with or scratching the finished paper roll, significantly improving paper roll production efficiency and product quality.
