Description

Technical Field

[0001] This application relates to the technical field of waste stone paper scraps processing, and in particular to a stone paper recycling feeding device. Background Technology

[0002] The manufacturing process of stone paper uses inorganic powders (such as calcium carbonate and talc) as the core raw materials, combined with polymer resins (polyethylene PE, polypropylene PP, etc.) and functional additives, and is achieved through thermoforming technology.

[0003] A stone paper recycling granulator is a device specifically designed to crush and granulate waste stone paper scraps. Its main function is to crush waste stone paper scraps and then granulate them using a specific process. The resulting granules can then be reused in the production of stone paper.

[0004] Generally, stone paper recycling feeding devices use a single screw structure. This structure is too simple, resulting in excessively long mixing time. Relying on the screw speed to crush the stone paper results in incomplete crushing, slow filling speed, and poor performance of the produced stone paper. Therefore, it is necessary to solve the problem of more thoroughly crushing waste stone paper scraps, improving feeding efficiency, ensuring more complete material filling, and improving product manufacturing quality. Summary of the Invention

[0005] The purpose of this application is to provide a stone paper recycling feeding device. The technical solution adopted is as follows:

[0006] It includes a feeding hopper, a drive motor, a first rotating shaft, and a second rotating shaft.

[0007] Both the first and second rotating shafts are located inside the feeding hopper. Both the first and second rotating shafts are horizontally arranged and parallel to each other. Both the first and second rotating shafts are rotatably connected to the feeding hopper. One end of both the first and second rotating shafts is connected to a drive motor, which is located outside the feeding hopper.

[0008] Both the first and second rotating shafts are provided with blades. The number of blades on the first rotating shaft is the same as that on the second rotating shaft. The blades are spiral structures and are connected to the first and second rotating shafts respectively.

[0009] By adopting the above technical solution, the spiral blades can crush materials under high-speed rotation, which can effectively improve the material feeding efficiency. At the same time, the twin screw structures work together to consume less energy and avoid overload, while making the material filling more complete and improving the product manufacturing quality.

[0010] Optionally, the blades of the first rotating shaft and the blades of the second rotating shaft have opposite helical directions.

[0011] By adopting the above technical solution, the reverse blade assembly enables the material to withstand bidirectional shearing force between the blades, crushing the material, preventing material blockage, and reducing idling losses.

[0012] Optionally, there are compression areas between the blades of the first rotating shaft and between the blades of the second rotating shaft, and the blades of the first rotating shaft are located in the compression area of ​​the second rotating shaft when rotating.

[0013] By adopting the above technical solution, when the shaft is rotating, it prevents adjacent blades from colliding and causing damage. At the same time, the blades can cooperate with each other to squeeze and convey the material from the direction of the feed inlet. Compared with single shaft conveying, the filling effect is obvious.

[0014] Optionally, the edge of the blade is a cutting edge, the cross-section of the cutting edge is wedge-shaped, and the inclined surface of the cutting edge forms a cutting angle of 10°-60° with the direction of rotation of the blade.

[0015] By adopting the above technical solution, when the blades rotate, the blades at the edge of the blades can cut the material well, allowing the material to enter more fully.

[0016] Optionally, the helix angle of the blade is less than 90 degrees.

[0017] By adopting the above technical solution, the blade edge will have a sliding effect with the material, which can better cut and crush the material and reduce rotational resistance.

[0018] Optionally, the blade is a detachable, split design, and the blade edge is provided with a dovetail groove, through which the blade is connected to the blade.

[0019] By adopting the above technical solution, the cutting edge can be quickly replaced, and only the worn module needs to be replaced, avoiding the scrapping of the entire blade and the waste of materials.

[0020] Optionally, the blade edge forms a continuous waveform structure along its length, which consists of alternating peak and trough segments.

[0021] By adopting the above technical solution, the wave structure divides the continuous chips into segments, reduces entanglement, and each wave crest independently bears the cutting load, thereby improving tool life.

[0022] Optionally, the first rotating shaft and the second rotating shaft rotate in opposite directions.

[0023] By adopting the above technical solution, the opposing rotating blades form a bidirectional material extrusion flow. The blades cooperate with each other, which can easily extrude and transport materials from the direction of the feed inlet.

[0024] Optionally, the feeding hopper includes a main body and a feeding port. The feeding port is detachably connected to the main body. After the upper end of the main body is detached from the feeding port, a maintenance port is formed at the upper end of the main body. The first rotating shaft and the second rotating shaft are rotatably connected to the main body.

[0025] By adopting the above technical solution, when it is necessary to replace the blade or repair the equipment, the feed port can be disassembled, and the blade replacement or equipment repair can be completed through the maintenance port.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The spiral blades allow the blades to slide with the material. The blades on the edge of the blades work in conjunction with the spiral structure to cut and crush the material, which can effectively improve the feeding efficiency of the material.

[0028] 2. The twin screws rotate in opposite directions and cooperate with each other, which can reduce the energy consumption of the device and prevent overload, while ensuring more complete material filling and improving product manufacturing quality.

[0029] 3. The detachable blades allow for quick replacement of the cutting edge, and only the worn module needs to be replaced, avoiding the scrapping of the entire blade and the waste of materials. The detachable feed port also creates a maintenance port at the top of the feed hopper, facilitating maintenance and blade replacement. Attached Figure Description

[0041] 5. Drive motor; Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0043] Example 1:

[0044] A stone paper recycling feeding device, as described in the reference Figure 1-5 The device includes a feeding hopper 1, a first rotating shaft 2, a second rotating shaft 3, and a drive motor 5. Both the first and second rotating shafts 2 and 3 are located inside the feeding hopper 1, while the drive motor 5 is located outside the feeding hopper 1. Both the first and second rotating shafts 2 and 3 are rotatably connected to the feeding hopper 1, and one end of each shaft is connected to the drive motor 5. Both the first and second rotating shafts 2 and 3 are equipped with blades 4, with the number of blades 4 on the first and second rotating shafts 2 and 3 being the same. The blades 4 have a helical structure with a helical angle of less than 90 degrees. The helical blades 4 allow for sliding between the blades and the material. The drive motor 5 causes the first and second rotating shafts 2 and 3 to rotate at high speed, breaking up the material with the blades 4, effectively improving the feeding efficiency. The twin screws work together to reduce energy consumption and prevent overload, while ensuring more complete material filling and improving product manufacturing quality.

[0045] The feed hopper 1 has a through opening at both the top and bottom. The feed hopper 1 includes a main body 11 and a feed inlet 12. A first rotating shaft 2 and a second rotating shaft 3 are rotatably connected to the main body 11. The feed inlet 12 is detachably connected to the main body 11 at its four corners via screws. After the feed inlet 12 is removed, a maintenance port is formed at the top of the main body 11, allowing for convenient maintenance. The feed inlet 12 has a trapezoidal vertical cross-section, with the upper base below the lower base, creating a free flow channel and reducing material conveying resistance.

[0046] Turn on the drive motor 5 and put the material into the feeding bin 1 through the feed inlet 12. The drive motor 5 drives the first rotating shaft 2 and the second rotating shaft 3 to rotate. The first rotating shaft 2 and the second rotating shaft 3 are both horizontally set and parallel to each other. The rotation directions of the first rotating shaft 2 and the second rotating shaft 3 are opposite. There are extrusion areas between the blades 4 of the first rotating shaft 2 and between the blades 4 of the second rotating shaft 3. When the blades 4 of the first rotating shaft 2 rotate, they are located in the extrusion area of ​​the second rotating shaft 3, so that the material is subjected to bidirectional shearing force in the extrusion area, which can crush the material and prevent large pieces of material from clogging the feeding bin 1. At the same time, it can also reduce the loss when idling. When the shaft is rotating, it prevents adjacent blades 4 from colliding and causing damage. At the same time, the blades 4 can cooperate with each other to extrude and convey the material from the direction of the feed inlet 12. Compared with single shaft conveying, the filling effect of the material is obvious.

[0047] The blades 4 of the first rotating shaft 2 and the blades 4 of the second rotating shaft 3 have opposite spiral directions. The edge of the blade 4 is a blade 41. The blade 41 is designed to be inclined, and the inclination direction is consistent with the rotation direction of the blade 4. The blade 41 and the rotation direction of the blade 4 form an inclination angle of 10°-60°, with 55° being the optimal inclination angle. This inclination angle is the cutting angle. The inclined design allows the blade 41 to better cut and crush the material.

[0048] When the blade 4 rotates, the blade 41 on the edge of the blade 4 can cut and crush the material, allowing the material to enter more fully. In addition, the blade 4 has a spiral structure, which allows the blade 41 to slide and cut the material, making the crushing effect of the material more significant. The blade 41 has a split and detachable design. The edge of the blade 4 is provided with a dovetail groove 42. The blade 41 is connected to the blade 4 through the dovetail groove 42 structure. The detachable design can realize quick replacement of the blade 41. At the same time, only the worn blade 41 needs to be replaced, avoiding the scrapping of the entire blade 4 and the waste of materials.

[0049] The implementation principle of this application embodiment is as follows: The drive motor 5 is turned on, and material is fed into the feed inlet 12. The drive motor 5 drives the blades 4 of the first rotating shaft 2 and the second rotating shaft 3 inside the main body 11 to rotate. The blades 4 and the second rotating shaft 3, rotating in opposite directions, work with the blades 41 on the edge of the blades 4 to cut and crush the material. The spiral blades 4 cause the blades 41 to slide against the material, resulting in a better cutting effect. If the machine malfunctions during the crushing process and requires repair or replacement of the blades 41, the drive motor 5 is turned off, and the feed inlet 12 can be disassembled. After disassembling the feed inlet 12, a maintenance port is formed at the upper end of the main body 11, allowing a single person to complete the repair or replacement of the blades 41.

[0050] Example 2:

[0051] This application discloses a stone paper recycling feeding device, which differs from Embodiment 1 in that the structure of the blade 41 on the blade 4 is different.

[0052] Specifically, refer to Figure 6-7 The cutting edge of the blade 41 forms a continuous wave structure along its length. This wave structure consists of alternating peaks and troughs. The peaks form the teeth, and the troughs form the grooves. The arc amplitude of the wave structure is small, and the peaks are designed to avoid sharp points, as sharp peaks can easily penetrate the material and cause it to rotate, leading to blockage. The grooves are also shallow to prevent broken material from getting stuck in the grooves during cutting, which would affect the feeding efficiency. The wave structure divides the continuous chips into segments, increasing cutting efficiency, reducing entanglement, and each peak independently bears the cutting load, thus improving tool life.

[0053] The implementation principle of this application embodiment is as follows: The drive motor 5 is turned on, and material is fed into the feed inlet 12. The drive motor 5 drives the blades 4 of the first rotating shaft 2 and the second rotating shaft 3 inside the main body 11 to rotate. The blades 4 and the second rotating shaft 3, rotating in opposite directions, work with the blades 41 on the edge of the blades 4 to cut and crush the material. The spiral blades 4 allow the blades 41 to slide against the material, resulting in a better cutting effect. The wave structure of the blades 41 reduces the entanglement of the crushed material. If the machine malfunctions during the crushing process and requires repair or replacement of the blades 41, the drive motor 5 is turned off, and the feed inlet 12 can be disassembled. After disassembling the feed inlet 12, a maintenance port is formed at the upper end of the main body 11, allowing a single person to complete the repair or replacement of the blades 41.

[0054] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
