Description

Technical Field

[0001] The present invention relates to the field of cup cover production, in particular to a wood pulp refiner used for cup cover production. Background Art

[0002] In the process of cup lid production (especially pulp molded cup lids, which use wood pulp as the main raw material), the wood pulp refiner is a key pre-treatment equipment. Its function is to convert wood pulp raw materials (such as wood pulp boards, wood pulp chips) into pulp with specific fiber morphology, beating degree and concentration through mechanical grinding and shearing, providing qualified raw materials for subsequent molding (such as hot pressing and vacuum molding), which directly affects the core performance of the cup lid, such as strength, surface smoothness, and water resistance.

[0003] During the wood pulp production process, eddy current mills are typically used to process the raw wood pulp. Once inside the mill, the raw wood pulp is driven into high-speed motion by the eddy currents. This creates intense collisions, friction, and shearing between the wood pulp particles, the inner walls of the grinding chamber, and the grinding media (such as steel and ceramic beads). This interaction continuously breaks, refines, and disperses the wood pulp fibers, achieving the desired grinding effect.

[0004] However, existing vortex grinders for wood pulp production lack screening mechanisms. Consequently, when wood pulp is poured into the grinder, it carries impurities such as bark with it, contaminating the raw material and reducing the quality of the ground wood pulp. Solving these problems has become a pressing issue for those skilled in the art. Summary of the Invention

[0005] In order to make up for the above shortcomings, the present invention provides a wood pulp refiner for cup lid production, which aims to solve the problem that the existing wood pulp eddy current grinder is unable to screen the wood pulp raw materials entering the grinder, thereby causing impurities such as bark to contaminate the wood pulp, resulting in a decrease in the quality of the ground wood pulp.

[0006] The present invention is achieved in that:

[0007] The present invention provides a wood pulp refiner for cup lid production, comprising a grinding chamber, a rotating disk, and a support rod, wherein the rotating disk is arranged inside the grinding chamber, and the support rod is fixedly connected to the bottom of the grinding chamber, and further comprising:

[0008] The filter assembly is arranged on the surface of the grinding chamber and is used to filter out impurities such as wood chips in the wood pulp.

[0009] A cleaning component is provided on the surface of the filter component and is used to ensure the stability of the filtering effect of the filter component.

[0010] An auxiliary component is arranged on the surface of the grinding bin, and is used to speed up the unloading speed of the wood pulp and improve the working efficiency of the wood pulp unloading.

[0011] Preferably, the filter assembly includes a motor, a hollow bin, a rotating shaft, a connecting piece, a rotating rod, a clamping piece and a push plate. The motor is fixedly connected to the bottom of the grinding bin, the hollow bin is arranged on the surface of the rotating disk, the rotating shaft is installed at the top output end of the motor, the connecting piece is installed on the surface of the hollow bin, the rotating rod is rotatably connected to the outer wall of the connecting piece, the clamping piece is fixedly connected to the surface of the rotating rod, and the push plate is fixedly connected to the outer wall of the rotating rod.

[0012] Preferably, a clamping plate is fixedly connected to the bottom of the hollow bin, and the clamping plate located at the bottom of the hollow bin is clamped with the grinding bin. The top end of the rotating shaft passes through the grinding bin and the rotating disk and extends to the outside of the rotating disk. The rotating shaft is rotatably connected to the grinding bin, and the rotating shaft is fixedly connected to the rotating disk.

[0013] By adopting the above technical solution, the hollow bin and the grinding bin are limited and fixed by the clamping plate. When the motor drives the rotating shaft to rotate, it can drive the rotating disk to rotate, thereby performing the pulping operation on the wood pulp through the rotating disk and the grinding bin.

[0014] Preferably, the rotating rod passes through the connecting piece and extends to the bottom of the connecting piece. A slot is provided at one end of the rotating rod extending to the bottom of the connecting piece. A clamping block is fixedly connected to the top of the rotating shaft. The clamping block at the top of the rotating shaft is engaged with the slot at the bottom end of the rotating rod. The clamping piece is located inside the connecting piece and is rotatably connected to the connecting piece. The push plate is obliquely arranged on the surface of the rotating rod, and a hole is provided on the surface of the push plate.

[0015] By adopting the above technical solution, when the rotating shaft rotates, the rotating rod can be driven to rotate through the clamping block and the clamping slot. The setting of the clamping parts can support the rotating rod. By opening holes on the surface of the inclined push plate 1, the resistance encountered by the push plate 1 during rotation can be reduced, thereby extending the service life of the push plate 1.

[0016] Preferably, the cleaning assembly includes a fixed rod, a rotating wheel, a spring push rod, a scraper and a sliding rod, the fixed rod is fixedly connected to the top end of the rotating rod, the rotating wheel is fixedly connected to the top end of the fixed rod, the spring push rod is fixedly connected to the surface of the rotating wheel, the scraper is arranged inside the hollow bin, and the sliding rod is arranged on the outer wall of the push plate.

[0017] Preferably, the scraper is in contact with the inner wall surface of the hollow bin, and the output end of the spring push rod is fixedly connected to the outer wall of the scraper.

[0018] By adopting the above technical solution, the surface of the hollow bin can be cleaned when the scraper rotates. During the rotation of the scraper, the spring push rod will be pulled to extend under the driving force of centrifugal force.

[0019] Preferably, the scraper is made of rubber, and the end of the sliding rod away from the push plate is fixedly connected to the outer wall of the scraper, one end of the sliding rod passes through the outer wall of the push plate and extends to the interior of the push plate, and the sliding rod is slidably connected to the interior of the push plate.

[0020] By adopting the above technical solution, the scraper made of rubber can avoid rigid collision with wood chips, which causes the wood chips to be crushed and enter the finished wood pulp through the hollow bin, resulting in a decrease in the quality of the wood pulp product. The scraper will drive the slide rod to slide inside the push plate under the action of the centrifugal force generated during the rotation process.

[0021] Preferably, the auxiliary components include a fixing ring, a connecting rod, a push plate 2, a grinding piece 1, a grinding piece 2, a valve tube and a cluster tube, the fixing ring is fixedly connected to the outer wall of the rotating shaft, the connecting rod is fixedly connected to the surface of the fixing ring, the push plate 2 is fixedly connected to the surface of the connecting rod, the grinding piece 1 is fixedly connected to the surface of the push plate 2, the grinding piece 2 is arranged on the outside of the push plate 2, the valve tube is fixedly connected to the bottom of the grinding bin, and the cluster tube is fixedly connected to the bottom end of the valve tube.

[0022] Preferably, the second grinding element is distributed on the surface of the grinding chamber and the bottom of the rotating disk, and the valve pipe is connected to the grinding chamber.

[0023] By adopting the above technical solution, the setting of grinding piece 2 and grinding piece 1 can assist the grinding chamber in grinding the wood pulp, and the setting of the valve pipe and the cluster pipe makes it convenient for the operator to collect the ground wood pulp later.

[0024] The beneficial effects of the present invention are:

[0025] 1. When the device is running, the motor drives the push plate to rotate through the rotating shaft and the rotating rod, thereby accelerating the rotation speed of the wood pulp inside the grinding chamber, so that the wood pulp passes through the hollow chamber under the action of centrifugal force and enters the grinding chamber for grinding. At the same time, the wood chips and other impurities inside the wood pulp will be filtered and screened by the hollow chamber to prevent wood chips and other impurities from entering the gap between the grinding chamber and the rotating disk and affecting the output quality of the wood pulp. This solves the problem that the existing wood pulp eddy current grinder cannot screen the wood pulp raw materials entering the grinder, resulting in contamination of the wood pulp by impurities such as bark, resulting in a decrease in the quality of the ground wood pulp.

[0026] 2. When the motor drives the rotating rod to rotate, the rotating rod will drive the scraper to rotate through the push plate and the wheel, so that the scraper drives the output end of the spring push rod to move under the action of centrifugal force and contact with the surface of the hollow bin, so that the scraper can clean the surface of the hollow plate. If the device stops running, the scraper will be separated from the hollow bin under the traction of the spring push rod to avoid the material on the surface of the hollow bin from drying and sticking to the scraper. When the scraper is started for the second time, the scraper surface will be damaged due to the adhesion of the raw materials, and the motor will be overloaded, which will extend the service life of the device as a whole.

[0027] 3. After the motor is started, the push plate 2 can be driven to rotate through the fixed ring, further accelerating the rotation speed of the wood pulp inside the grinding chamber, so that the centrifugal force of the wood pulp is further increased. When unloading, the wood pulp can be thrown out of the grinding chamber by centrifugal force and discharged through the valve pipe and the cluster pipe, which improves the efficiency of wood pulp unloading and reduces the time consumed in wood pulp unloading.

[0039] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Example 1: Reference Figure 1 and Figure 3-Figure 7 A wood pulp refiner for cup lid production includes a grinding chamber 1, a rotating disk 2 and a support rod 3, wherein the rotating disk 2 is arranged inside the grinding chamber 1, and the support rod 3 is fixedly connected to the bottom of the grinding chamber 1, and further includes:

[0041] The filter assembly 4 is arranged on the surface of the grinding chamber 1 and is used to filter out impurities such as wood chips in the wood pulp.

[0042] The cleaning component 5 is arranged on the surface of the filter component 4 and is used to ensure the stability of the filtering effect of the filter component 4.

[0043] The auxiliary component 6 is arranged on the surface of the grinding chamber 1. The auxiliary component 6 is used to speed up the unloading speed of the wood pulp and improve the working efficiency of the wood pulp unloading.

[0044] The filter assembly 4 includes a motor 401, a hollow chamber 402, a rotating shaft 403, a connecting piece 404, a rotating rod 405, a clamping piece 406 and a push plate 407. The motor 401 is fixedly connected to the bottom of the grinding chamber 1, the hollow chamber 402 is arranged on the surface of the rotating disk 2, the rotating shaft 403 is installed at the top output end of the motor 401, the connecting piece 404 is installed on the surface of the hollow chamber 402, the rotating rod 405 is rotatably connected to the outer wall of the connecting piece 404, the clamping piece 406 is fixedly connected to the surface of the rotating rod 405, and the push plate 407 is fixedly connected to the outer wall of the rotating rod 405.

[0045] It should be noted that: the bottom of the hollow bin 402 is fixedly connected with a card plate, the card plate at the bottom of the hollow bin 402 is clamped with the grinding bin 1, the hollow bin 402 and the grinding bin 1 are fixed by the card plate, the top of the rotating shaft 403 passes through the grinding bin 1 and the rotating disk 2, and extends to the outside of the rotating disk 2, the rotating shaft 403 is rotatably connected to the grinding bin 1, the rotating shaft 403 is fixedly connected to the rotating disk 2, when the motor 401 drives the rotating shaft 403 to rotate, it can drive the rotating disk 2 to rotate, so that the wood pulp is refined by the rotating disk 2 and the grinding bin 1, the rotating rod 405 passes through the connecting piece 404, and extends to the bottom of the connecting piece 404, the rotating rod 405 extends to the connecting piece 404 A slot is provided at one end of the lower part, and a block is fixedly connected to the top of the rotating shaft 403. The block at the top of the rotating shaft 403 is engaged with the slot at the bottom end of the rotating rod 405. When the rotating shaft 403 rotates, the rotating rod 405 can be driven to rotate by the block and the slot. The clamp 406 is located inside the connecting member 404 and is rotatably connected to the connecting member 404. The setting of the clamp 406 can support the rotating rod 405. The push plate 407 is tilted and set on the surface of the rotating rod 405, and a hole is provided on the surface of the push plate 407. By providing a hole on the inclined surface of the push plate 407, the contact resistance with the wood pulp during rotation is reduced, and the wear of the components is reduced, thereby extending the service life of the push plate 407.

[0046] When the device is running, the motor 401 drives the push plate 407 to rotate through the rotating shaft 403 and the rotating rod 405, thereby accelerating the rotation speed of the wood pulp inside the grinding chamber 1, so that the wood pulp passes through the hollow chamber 402 under the action of centrifugal force and enters the grinding chamber 1 for grinding processing. At the same time, impurities such as wood chips inside the wood pulp will be filtered and screened by the hollow chamber 402, so as to prevent impurities such as wood chips from entering between the grinding chamber 1 and the rotating disk 2 and affecting the output quality of the wood pulp, thereby solving the problem that the existing wood pulp eddy current grinder cannot screen the wood pulp raw materials entering the grinder, thereby causing impurities such as bark to contaminate the wood pulp, resulting in a decrease in the quality of the ground wood pulp. When the motor 401 drives the rotating shaft 403 to rotate, the rotating rod 405 drives the push plate 407 to rotate, and the inclined push plate 407 forms a spiral guiding force, which prompts the wood pulp to flow to the sieve holes of the hollow chamber 402. Furthermore, since holes are provided on the surface of the push plate 407, the wood pulp can be dispersed for a second time through the holes while reducing the impact resistance of the wood pulp, thereby avoiding uneven filtration caused by local accumulation.

[0047] The wood pulp to be ground is poured into the grinding bin 1 and piled up inside the hollow bin 402. The motor 401 is started. The motor 401 drives the rotating rod 405 and the rotating disk 2 to rotate through the rotating shaft 403. When the rotating shaft 403 rotates, the push plate 407 is driven to rotate through the rotating rod 405, and the rotating disk 2 is driven to rotate at the same time. At this time, the wood pulp accumulated inside the hollow bin 402 will be centrifugally rotated under the drive of the push plate 407. During the centrifugal rotation, the wood pulp will be thrown out of the hollow bin 402 under the action of centrifugal force, and move to between the grinding bin 1 and the rotating disk 2, and be ground under the action of the grinding bin 1.

[0048] The cleaning assembly 5 includes a fixed rod 501, a rotating wheel 502, a spring push rod 503, a scraper 504 and a sliding rod 505. The fixed rod 501 is fixedly connected to the top of the rotating rod 405, the rotating wheel 502 is fixedly connected to the top of the fixed rod 501, the spring push rod 503 is fixedly connected to the surface of the rotating wheel 502, the scraper 504 is arranged inside the hollow bin 402, and the sliding rod 505 is arranged on the outer wall of the push plate 407.

[0049] The scraper 504 is in contact with the inner wall surface of the hollow bin 402. When the scraper 504 rotates, the surface of the hollow bin 402 can be cleaned. The output end of the spring push rod 503 is fixedly connected to the outer wall of the scraper 504. During the rotation of the scraper 504, the spring push rod 503 will be pulled to extend under the driving force of the centrifugal force. The scraper 504 is made of rubber. The scraper 504 made of rubber can avoid rigid collision with the wood chips, causing the wood chips to be crushed and enter the finished wood pulp through the hollow bin 402, resulting in a decrease in the quality of the wood pulp product. The end of the slide rod 505 away from the push plate 407 is fixedly connected to the outer wall of the scraper 504, and one end of the slide rod 505 passes through the outer wall of the push plate 407 and extends to the interior of the push plate 407. The slide rod 505 is slidably connected to the interior of the push plate 407. The scraper 504 will drive the slide rod 505 to slide inside the push plate 407 under the action of the centrifugal force generated during the rotation.

[0050] When the motor 401 drives the rotating rod 405 to rotate, the rotating rod 405 will drive the scraper 504 to rotate through the push plate 407 and the rotating wheel 502, so that the scraper 504 drives the output end of the spring push rod 503 to move under the action of centrifugal force and contact the surface of the hollow bin 402, so that the scraper 504 can clean the surface of the hollow plate. If the device stops running, the scraper 504 will be pulled away from the hollow bin 402 by the spring push rod 503, so as to avoid the material on the surface of the hollow bin 402 from drying and sticking to the scraper 504, which will cause the scraper 504 to During the second start-up, the surface of the scraper 504 is damaged due to the adhesion of the raw materials, which causes the motor 401 to be overloaded, thus extending the service life of the entire device. When the spring push rod 503 automatically resets, the scraper 504 will be separated from the warehouse wall under the traction of the spring push rod 503, which completely solves the startup jamming problem of the traditional fixed scraper 504 caused by the dry material. Since the scraper 504 is made of wear-resistant rubber material, it can avoid the rigid friction with the metal hollow warehouse 402 to generate debris, and at the same time, it can conform to the concave and convex surface of the warehouse wall through elastic deformation.

[0051] When the motor 401 drives the fixed rod 501 and the rotating wheel 502 to rotate through the rotating shaft 403 and the rotating rod 405, the scraper 504 will move under the driving force of the centrifugal force and contact the surface of the hollow bin 402. At the same time, the scraper 504 will rotate on the surface of the hollow bin 402 under the driving force of the spring push rod 503 and the sliding rod 505, thereby cleaning the surface of the hollow bin 402.

[0052] Example 2: Please refer to Example 1 for details. Figure 1 、 Figure 2 and Figure 8 、 Figure 9The auxiliary component 6 includes a fixed ring 601, a connecting rod 602, a push plate 2 603, a grinding piece 1 604, a grinding piece 2 605, a valve pipe 606 and a cluster pipe 607. The fixed ring 601 is fixedly connected to the outer wall of the rotating shaft 403, the connecting rod 602 is fixedly connected to the surface of the fixed ring 601, the push plate 2 603 is fixedly connected to the surface of the connecting rod 602, the grinding piece 1 604 is fixedly connected to the surface of the push plate 2 603, the grinding piece 2 605 is arranged on the outside of the push plate 2 603, the valve pipe 606 is fixedly connected to the bottom of the grinding chamber 1, and the cluster pipe 607 is fixedly connected to the bottom end of the valve pipe 606.

[0053] It should be noted that: grinding piece 2 605 is distributed on the surface of the grinding chamber 1 and the bottom of the rotating disk 2. The setting of grinding piece 2 605 and grinding piece 1 604 can assist the grinding chamber 1 in grinding the wood pulp. The valve pipe 606 is connected to the grinding chamber 1. The setting of valve pipe 606 and cluster pipe 607 makes it convenient for the operator to collect the ground wood pulp later.

[0054] After the motor 401 is started, the push plate 2 603 can be driven to rotate through the fixed ring 601, further accelerating the rotation speed of the wood pulp inside the grinding chamber 1, so that the centrifugal force of the wood pulp is further increased. When unloading, the wood pulp can be thrown out of the grinding chamber 1 by centrifugal force and discharged through the valve tube 606 and the cluster tube 607, thereby improving the efficiency of wood pulp unloading and reducing the time consumed in wood pulp unloading. The staggered grinding structure formed by the grinding piece 1 604 and the grinding piece 2 605 will cause the push plate 2 603 to rotate with the rotating shaft 403, driving the wood pulp to form turbulence between the grinding pieces. Through the combined action of "shear-extrusion-grinding", the wood pulp fibers are further refined, thereby improving the product quality of the wood pulp cup cover. In the unloading stage, after opening the valve tube 606, the rotation of the push plate 2 603 generates radial centrifugal force, which cooperates with the axial thrust formed by the connecting rod 602 driven by the fixed ring 601, so that the discharge speed of the wood pulp through the valve tube 606 is further increased. The conical design of the cluster tube 607 can be directly connected to the feed port of subsequent molding equipment, reducing pipeline residue and secondary pollution.

[0055] When the motor 401 is started, the push plate 2 603 is driven to rotate through the rotating shaft 403 and the connecting rod 602, thereby further enhancing the centrifugal rotation effect of the wood pulp inside the grinding chamber 1. When unloading, the wood pulp will be thrown out under the action of centrifugal force and flow to the inside of the valve tube 606 and discharged through the cluster pipe 607.

[0056] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
