Description

Technical Field

[0001] This utility model relates to the field of yarn tube paper pulp manufacturing technology, and in particular to a mill for yarn tube paper pulp manufacturing. Background Technology

[0002] Paper tube pulp is the raw material pulp used to produce paper tubes. It is typically made from waste paper or wood pulp, processed to form pulp with specific fiber length, strength, and uniformity, meeting the requirements of paper tubes for stiffness, compressive strength, and other properties. A mill is used during manufacturing because it uses mechanical shearing, squeezing, and friction to thoroughly separate and fluff the fibers in the raw material, removing impurities and resulting in more uniform pulp fibers with stronger bonding, thus ensuring that the subsequently produced paper tubes meet quality standards.

[0003] Most mills utilize a grinding disc and a grinding groove, using the teeth on the surface of the grinding disc to generate shearing and extrusion effects to achieve fiberization. However, before use, the grinding disc needs to be installed. Most installations involve placing the grinding disc in the grinding groove and then tightening the nut to complete the installation. However, during mill operation, the grinding disc rotates at high speed and violently rubs and impacts the raw material, generating continuous vibration and impact force. Over a long period of time, the preload between the nut and the thread will gradually decrease, causing the connection to loosen, which in turn leads to a sharp drop in grinding effect.

[0004] Therefore, it is necessary to provide a new mill for manufacturing paper tube pulp to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a mill for manufacturing paper tube pulp.

[0006] This utility model provides a mill for manufacturing paper tube pulp, comprising: a base frame, an auger blade, a drive assembly, and a feed frame. The top of the base frame is symmetrically fixedly connected to feet, and a receiving tank is fixedly connected to the top of two of the feet. A conveying hole is formed on the inner wall of the receiving tank. A rotating rod is rotatably connected to the inner wall of the middle section of the receiving tank. A grinding chamber is formed on one side of the receiving tank. A fixed plate is fixedly connected to the outer left side of the rotating rod. Multiple limiting rods are fixedly connected to the left side of the fixed plate. A grinding disc is slidably connected to the outer side of the multiple limiting rods. An auger blade is fixedly connected to the outer side of the rotating rod and moves within the inner wall of the conveying hole. Multiple limiting grooves are formed on the outer left side of the rotating rod. Two limiting blocks are slidably connected to the inner wall of each limiting groove. Metal washers are fixedly connected to the outer side of every four limiting blocks. A spring is sleeved between two of the metal washers on the outer side of the rotating rod. A nut is threadedly connected to the leftmost outer side of the rotating rod. A drive assembly is installed on one side of the top of the base frame. A feed frame is fixedly connected to the top of the receiving tank, and a hopper is fixedly connected to the top of the feed frame.

[0007] Preferably, the drive assembly includes a motor, the bottom end of which is fixedly connected to the top end of the base frame, a drive wheel is fixedly connected to the drive end of the motor, a driven wheel is rotatably connected to the side of the receiving barrel away from the grinding chamber, and pulleys are sleeved on the outside of the drive wheel and the driven wheel.

[0008] Preferably, the outer diameter of the fixed disk is smaller than the inner diameter of the conveying hole, and the grinding disk fits into the grinding cavity.

[0009] Preferably, the inner wall of the metal washer is slidably connected to the outer side of the rotating rod.

[0010] Preferably, the two metal washers are fixedly connected to the two ends of the spring on adjacent sides.

[0011] Preferably, the right side of the metal washer on the right side is in close contact with the left side of the grinding disc, and the right side of the nut is in contact with the left side of the metal washer on the left side.

[0012] Preferably, the driven wheel is fixedly connected to the right end of the rotating rod at the axis on the side closest to the receiving barrel.

[0013] Compared with related technologies, the mill for manufacturing paper tube pulp provided by this utility model has the following beneficial effects:

[0014] Improved grinding disc connection stability: Through the cooperative structure of the left-side limiting groove of the rotating rod, the limiting block, the metal washer, the spring and the nut, when the rotating rod tends to move axially due to vibration during mill operation, the elastic deformation of the spring buffers the movement, the metal washer limits the movement and the nut tightens the position of the grinding disc on the limiting rod, thus preventing the grinding disc connection from loosening. This solves the problem of grinding disc loosening caused by mill vibration and ensures continuous and stable grinding.

[0015] More reliable grinding effect: The stable grinding disc and grinding chamber can continuously and evenly grind and fiberize the raw materials. Compared with traditional mills where the grinding effect fluctuates due to loose grinding discs, this mill can make the pulp fibers of yarn tube paper evenly separated, meeting the pulp performance requirements of yarn tube paper production.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 A mill for manufacturing paper tube pulp includes: a base frame 1, which serves as the basic support structure for the entire equipment. The base frame 1 has feet 2 fixedly connected to its top, and a receiving tank 3 is securely connected to the top of each foot 2, serving to support and elevate the receiving tank 3. The receiving tank 3 is used to hold the raw materials to be processed and to perform grinding operations. A conveying hole 4 is provided on its inner wall. A rotating rod 5 is rotatably connected to the inner wall of the middle end of the receiving tank 3. A grinding chamber 6 is provided on one side of the receiving tank 3. The grinding chamber 6 is for raw materials... The grinding and fiberizing process provides a working space. A fixed plate 7 is fixedly connected to the outer left side of the rotating rod 5. The fixed plate 7 serves as a connection and limiter. Multiple limit rods 8 are fixedly connected to its left side. These limit rods 8 are arranged in a certain layout. The grinding disc 9 is connected to the outside of the multiple limit rods 8 in a sliding fit. At the same time, the outer diameter of the fixed plate 7 is designed to be smaller than the inner diameter of the conveying hole 4. This size design is to meet the needs of the internal space layout of the equipment and material conveying. The grinding disc 9 fits into the grinding cavity 6 to ensure the smooth progress of the grinding operation.

[0024] The auger blade 10 is fixedly connected to the outside of the rotating rod 5. The auger blade 10 moves within the inner wall of the conveying hole 4. When the rotating rod 5 rotates, it conveys and initially extrudes the raw material. Multiple limiting grooves 11 are provided on the outer left side of the rotating rod 5. Two limiting blocks 12 are slidably connected to the inner wall of each limiting groove 11. The limiting blocks 12 can slide within the limiting groove 11, playing the role of limiting and transmitting force. Metal gaskets 13 are fixedly connected to every four limiting blocks 12. The inner wall of the metal gaskets 13 is slidably connected to the outside of the rotating rod 5, ensuring that it can slide on the rotating rod 5. A spring 14 is sleeved between two metal gaskets 13 on the outside of the rotating rod 5. The adjacent side of the two metal gaskets 13 is fixedly connected to the two ends of the spring 14, so that the elastic force of the spring 14 can act on the metal gaskets 13. A nut 15 is connected to the outer left side of the rotating rod 5 by a threaded connection.

[0025] The drive assembly is a key component that provides power to the equipment. The drive assembly is installed on one side of the top of the base frame 1. The drive assembly includes a motor 16, which serves as the power source. Its bottom end is fixedly connected to the top of the base frame 1 to ensure the stability of the motor 16 during operation. The drive end of the motor 16 is fixedly connected to a drive wheel 17, which is used to transmit the power of the motor 16. A driven wheel 18 is rotatably connected to the side of the receiving tank 3 away from the grinding chamber 6. A pulley 19 is fitted around the drive wheel 17 and the driven wheel 18, which transmits power from the drive wheel 17 to the driven wheel 18. The shaft of the driven wheel 18 near the receiving tank 3 is fixedly connected to the right end of the rotating rod 5, thereby transmitting power to the rotating rod 5. The feed frame 20 is fixedly connected to the top of the receiving tank 3 to receive and introduce the raw materials to be processed. A hopper 21 is fixedly connected to the top of the feed frame 20, which facilitates the operator to pour the raw materials into the equipment.

[0026] The working principle of the mill for manufacturing paper tube pulp provided by this utility model is as follows:

[0027] First, the motor 16 in the drive assembly is started. The motor 16 drives the drive wheel 17 to rotate. The drive wheel 17 drives the driven wheel 18 to rotate through the pulley 19. The driven wheel 18 then drives the rotating rod 5 to start rotating. The operator pours the raw material of the yarn tube paper pulp to be processed into the feed frame 20 through the hopper 21. The raw material enters the receiving tank 3 along the feed frame 20. As the rotating rod 5 rotates, the auger blade 10 fixedly connected to its outside also rotates synchronously. The auger blade 10 moves in the inner wall of the conveying hole 4, which plays a role in conveying and initially squeezing the raw material entering the receiving tank 3, and gradually pushes the raw material towards the grinding chamber 6. When the rotating rod 5 rotates, the fixed plate 7, the limiting rod 8 and other components on its left side rotate accordingly. The grinding disc 9 rotates with the rotating rod 5 under the restriction of the limiting rod 8. When the raw material is conveyed to the position of the grinding chamber 6, the rotating grinding disc 9 cooperates with the grinding chamber 6, and uses the structure on the surface of the grinding disc 9 to grind and fiberize the raw material, realizing the key steps of yarn tube paper pulp manufacturing.

[0028] During the operation of the mill, the rotating rod 5 may experience slight axial movement due to vibrations generated during grinding. If the rotating rod 5 tends to move axially, the metal shim 13 will compress the spring 14 under the restriction of the limiting groove 11 and the limiting block 12. The elastic deformation of the spring 14 can buffer this movement. At the same time, the nut 15, through its threaded connection with the rotating rod 5, works with the metal shim 13 and the spring 14 to ensure the relative position of the grinding disc 9 on the limiting rod 8 is stable, thus maintaining the stable operation of the grinding work in the grinding chamber 6.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
