Description

Technical Field

[0001] This invention belongs to the field of ink processing technology, and specifically relates to a grinding machine for ink processing. Background Technology

[0002] In the process of ink processing, the raw materials need to be ground.

[0003] Existing ink processing grinding mills, while meeting the basic requirements for grinding ink raw materials and capable of sieving the ground materials to remove large, insufficiently ground particles, typically employ fixed, inclined screens. During operation, some small particles are easily swept up by the sliding of larger particles and discharged through the discharge port. This results in some incompletely ground small particles being mistakenly discharged. Subsequent secondary grinding of the incompletely ground large particles leads to ineffective grinding of these mistakenly discharged small particles, impacting the overall processing efficiency of the equipment and causing unnecessary wear. Therefore, they fail to fully meet user needs. Summary of the Invention

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a grinding machine for ink processing, which not only meets the basic requirements for grinding ink raw materials, but also fully screens the pulverized ink raw materials, thereby more fully meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a grinding machine for ink processing, including a grinding box, a grinding module is provided at the upper end of the grinding box, a screening trough that can vibrate vertically and is located below the grinding module is provided inside the grinding box, the lower end of the screening trough is conical, a feeding pipe is provided at the bottom of the screening trough, a control valve is provided on the feeding pipe, a discharge pipe is provided at the side end of the grinding box, a discharge hopper is provided on the discharge pipe, an installation frame is slidably provided at the side end of the grinding box, and a shielding cover that can cover the discharge hopper and a collection hopper adapted to the discharge hopper are provided on the installation frame.

[0006] As a further improvement of the present invention, the grinding module includes a mounting shaft rotatably disposed on the front and rear side walls of the grinding box, a grinding roller disposed on the mounting shaft, a gear transmission assembly located on the outside of the grinding box, and a guide hopper located on the inner wall of the grinding box below the two grinding boxes.

[0007] As a further improvement of the present invention, a drive motor is also provided on the outer wall of the grinding box, and a transmission gear is provided between the output shaft of the drive motor and the gear transmission assembly.

[0009] As a further improvement of the present invention, the support frame is also provided with a guide slot, and the fixed frame is provided with a guide plate that is inserted into the guide slot.

[0010] As a further improvement of the present invention, a protective cover is also provided at the bottom of the support frame, which covers the outside of the screening trough.

[0011] As a further improvement of the present invention, a feed hopper is provided at the top of the grinding box, a discharge pipe is provided at the bottom of the grinding box, and a support leg is also provided at the bottom side of the grinding box.

[0012] As a further improvement of the present invention, a transparent observation window is also provided on the grinding box. The design of the transparent observation window allows the operator to easily observe the grinding and screening process, and facilitates the monitoring and adjustment of the screening operation of the sieve and the discharge of large particles of raw materials.

[0013] As a further improvement of the present invention, a telescopic push rod is provided on the side end of the grinding box, the output shaft of the telescopic push rod passes through the side wall of the grinding box and is connected to the mounting frame, and a support groove is provided on the side end of the grinding box that is slidably connected to the mounting frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] Firstly, this invention not only enables efficient grinding of ink raw materials, but also includes a sieve trough to fully sieve the ground materials, preventing small graphite particles from sliding directly onto the outside of the device along with large graphite particles, thereby ensuring the thoroughness and uniformity of the finished product particles and meeting the needs of high-quality ink production.

[0016] Secondly, the grinding module adopts a structure combining a mounting shaft and a grinding roller, along with a gear transmission assembly and a drive motor, to achieve a stable and efficient grinding effect; the design of the guide hopper ensures that the ground material smoothly enters the screening area, improving the overall operating efficiency of the equipment.

Detailed Implementation

[0025] To better understand the present invention, the following embodiments further illustrate the content of the invention, but the scope of protection of the present invention is not limited to the following embodiments. Numerous specific details are set forth in the following description to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details.

[0026] like Figure 1 , 2As shown in Figures 1 and 3, a grinding machine for ink processing includes a grinding box 101. A grinding module is located at the upper end of the grinding box 101. A sieve trough 102, capable of vertical vibration and located below the grinding module, is located inside the grinding box 101. The lower end of the sieve trough 102 is conical. A discharge pipe 103 is also provided at the bottom of the sieve trough 102, and a control valve 104 is also provided on the discharge pipe 103. A discharge pipe 105 is also provided on the side end of the grinding box 101, and a discharge hopper 106 is provided on the discharge pipe 105. A mounting frame 107 is slidably mounted on the side end of the grinding box 101. The mounting frame 107 is equipped with a shielding cover 108 that can block the discharge hopper 106 and a collecting hopper 109 adapted to the discharge hopper 106. The shielding cover 108 is conical, which can effectively prevent ink raw materials from remaining on the shielding cover 108.

[0027] like Figure 2 As shown, the grinding module includes a mounting shaft 201 rotatably mounted on the front and rear side walls of the grinding box 101. A grinding roller 202 is mounted on the mounting shaft 201. A gear transmission assembly 203 located on the outside of the grinding box 101 is also mounted on the mounting shaft 201. A guide hopper 204 located on the lower side of the two grinding boxes 101 is also mounted on the inner wall of the grinding box 101.

[0028] like Figure 1 As shown, a drive motor 205 is also provided on the outer wall of the grinding box 101, and a transmission gear 206 is provided between the output shaft of the drive motor 205 and the gear transmission assembly 203.

[0029] like Figure 1 , 2 As shown, a support frame 301 is provided on the inner wall of the grinding box 101. A vibration spring 302 is vertically provided on the support frame 301. A fixed frame 303 is provided at the upper end of the vibration spring 302. The screening trough 102 is connected to the fixed frame 303. A vibration motor 304 is also provided on the fixed frame 303. A striking block is also provided on the fixed frame 303 via a vertical rod for vibrating and striking the bottom of the guide hopper 204.

[0030] like Figure 2 , 3 As shown, the support frame 301 is also provided with a guide slot 305, and the fixed frame 303 is provided with a guide plate 306 that is inserted into the guide slot 305.

[0031] like Figure 2 As shown, the bottom of the support frame 301 is also provided with a protective cover 307 covering the outside of the screening trough 102.

[0032] like Figure 3As shown, the grinding box 101 has a feed hopper 110 at the top, a cone-shaped bottom, a discharge pipe 111 at the bottom, and a support leg 112 at the bottom side of the grinding box 101.

[0033] like Figure 4 As shown, a telescopic push rod 114 is provided on the side end of the grinding box 101. The output shaft of the telescopic push rod 114 passes through the side wall of the grinding box 101 and is connected to the mounting frame 107. A support groove 115 is provided on the side end of the grinding box 101, which is slidably connected to the mounting frame 107. Through the support groove 115, the telescopic push rod 114 can stably drive the mounting frame 107 to slide, thereby enabling the mounting frame 107 to slide stably and preventing the telescopic push rod 114 from being easily damaged by deformation.

[0034] The worker first starts the drive motor 205, which drives the gear transmission assembly 203 through the transmission gear 206, thereby driving the mounting shaft 201 and the grinding roller 202 to rotate, preparing for the grinding of the ink raw materials; then the ink raw materials to be ground can be put into the equipment through the feed hopper 110. After the ink raw materials fall onto the grinding roller 202, they will be ground. The ground material falls into the guide hopper 204 on the lower side of the inner wall of the grinding box 101, and the guide hopper 204 guides the material to the screening area.

[0035] Then, the vibration motor 304 can be started. With the vibration of the vibration spring 302 and the insertion of the guide slot 305 and the guide plate 306, the fixed frame 303 and the sieve trough 102 will vibrate vertically to screen the ground material. Fine particles that meet the particle size requirements will pass through the sieve holes of the sieve trough 102 and fall to the lower side of the grinding box 101 and be discharged through the discharge pipe 111. Large particles that are not sufficiently ground will be trapped in the sieve trough 102 because they cannot pass through the sieve holes. During this screening process, the shield 108 will cover the outside of the sieve trough 102 to prevent graphite material from entering precision components such as the vibration spring 302, the guide slot 305 and the guide plate 306, ensuring the stable operation of the screening system and extending the service life of the equipment.

[0036] During the vibration operation, the fixed frame 303 and the sieve 102 will also drive the vertical rod, the mounting frame 107 and the striking block to vibrate vertically, thereby intermittently striking the guide hopper 204, so that the ground ink raw material in the guide hopper 204 can be discharged more fully and smoothly.

[0037] After a period of time, once enough large particles of raw material have been retained in the screening trough 102, the addition of ink raw material to be ground into the feed hopper 110 can be stopped. Then, the output shaft of the telescopic push rod 114 can be shortened by a certain length, driving the mounting frame 107 to move, so that the shield 108 moves away from the upper side of the discharge hopper 106, and the collecting hopper 109 moves to the upper side of the discharge hopper 106. Then, the control valve 104 can be opened, and the large particles of raw material retained in the screening trough 102 will smoothly leave the vibrating screening trough 102 through the discharge pipe 103, and leave the grinding box 101 through the collecting hopper 109, the discharge hopper 106, and the discharge pipe 105.

[0038] Then the output shaft of the telescopic push rod 114 extends to a certain length, causing the collecting hopper 109 and the discharging hopper 106 to be misaligned, and the shield 108 to cover the discharging hopper 106 again; then the ink raw materials to be ground can continue to be added to the feeding hopper 110, and the ink raw materials can continue to be ground and screened.

[0039] According to another embodiment of the invention, such as Figure 1 As shown, a transparent observation window 113 is also provided on the grinding box 101. The design of the transparent observation window 113 makes it convenient for operators to observe the grinding and screening process, and to monitor and adjust the screening operation of the sieve 102 and the discharge of large particles of raw materials.

[0040] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
