Description

Technical Field

[0001] This utility model relates to the field of toner technology, specifically to a pulverizing device for the production and processing of ultrafine toner. Background Technology

[0002] Toner, also known as carbon powder, is a key material used in laser printers and copiers for imaging and fixing images on paper. Toner is mainly composed of polymer resin and carbon black or pigment, and also contains some charge control agents and additives (such as magnetic powder, lubricants, etc.) to adjust the electrostatic properties of the toner. This allows the toner to fix the image onto the paper during the printing process, forming the required image information on the paper. During toner production, the coarse toner raw material needs to be crushed by a crushing device to achieve a suitable particle size. The crushing device uses an external high-pressure airflow to cause the coarse toner raw material to collide with the inner wall of the crushing barrel or with each other, thereby refining the coarse toner raw material and obtaining very fine toner particles that cannot be obtained by ordinary grinding and crushing.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: when existing crushing devices crush coarse toner raw materials, because the toner raw materials are mixed with magnetic powder, some toner is easily attached to the inner wall of the crushing barrel of the crushing device due to magnetic force during the crushing process. It is necessary to wait for the high-pressure airflow to blow it off, which makes it difficult for some coarse toner particles to be fully collided and crushed, resulting in a decrease in crushing speed and uniformity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a pulverizing device for the production and processing of ultrafine toner with high pulverizing speed and good pulverizing uniformity.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a crushing device for the production and processing of ultrafine toner, comprising a crushing cylinder body and a feed pipe disposed on one side of the bottom of the crushing cylinder body, an air inlet pipe disposed on the other side of the bottom of the crushing cylinder body, a classifier disposed on the top of the crushing cylinder body, an extraction device disposed on the top of the classifier, the crushing cylinder body comprising an outer shell, and a repulsion ring slidably sleeved on the outer wall of the outer shell.

[0006] A further improvement is that the outer wall of the outer shell is also provided with several positioning tracks that can cooperate with the repulsion ring.

[0007] A further improvement is that a weighing base is provided at the bottom of the outer casing.

[0008] A further improvement is that the bottom of the repulsion ring is provided with a buffer structure, which includes a silicone block fixedly connected to the bottom of the repulsion ring and a buffer spring disposed on the bottom surface of the silicone block.

[0009] A further improvement is that the repulsion ring includes a collar that is slidably sleeved on the outer wall of the outer shell and an electromagnet disposed within the collar, wherein the outer wall of the electromagnet is provided with a power inlet that penetrates the collar.

[0010] A further improvement is that the outer wall of the ring is provided with several handles.

[0011] A further improvement is that the inner wall of the collar is provided with a sliding block that can cooperate with the positioning track.

[0012] A further improvement is that the inner wall of the collar is also provided with a polished layer.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When crushing, this utility model can repeatedly pull the repulsion ring up and down, thereby making the repulsion ring adhere to the outer shell and move up and down. At the same time, the current is connected to the power port, which can make the electromagnet generate a magnetic force with the same magnetism as the toner. Then, the toner is pushed off the inner wall of the outer shell by the repulsion of like poles, so that it re-enters the cavity inside the outer shell for collision and crushing. This avoids the phenomenon that the toner adheres to the inner wall of the outer shell and cannot be fully crushed, improves the crushing speed, and makes the crushed toner more uniform.

[0017] Figure 3 This is a top view structural diagram of the repulsion ring of this utility model. Detailed Implementation

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a crushing device for ultrafine toner production and processing, including a crushing cylinder body 1 and a feed pipe 2 disposed on one side of the bottom of the crushing cylinder body 1. An air inlet pipe 3 is also provided on the other side of the bottom of the crushing cylinder body 1. A classifier 5 is provided on the top of the crushing cylinder body 1, and an extraction device 6 is provided on the top of the classifier 5. The crushing cylinder body 1 includes an outer shell 11, and a repulsion ring 13 is slidably fitted on the outer wall of the outer shell 11. The repulsion ring 13 includes a collar 131 slidably fitted on the outer wall of the outer shell 11 and an electromagnet 132 disposed within the collar 131. The outer wall of the electromagnet 132 is provided with a power inlet 136 penetrating the collar 131. In use, coarse toner particles to be crushed are fed into the outer shell 11 through the feed pipe 2, and high-pressure air is introduced into the outer shell 11 of the crushing cylinder body 1 from the air inlet pipe 3 on the other side of the outer shell 11. This causes the coarse toner particles fed into the outer casing 11 to be blown away by high-pressure gas, moving within the casing 11 and colliding with each other while impacting and breaking into tiny particles against the inner wall of the casing 11. When the particles reach the target size, they can be passed through the classifier 5 and the finished toner can be extracted and collected by the extraction device 6. During the crushing process, the repulsion ring 13 can be pulled up and down repeatedly, causing the collar 131 of the repulsion ring 13 to adhere to the casing 11 and move up and down. At the same time, current is connected to the power port 136, which causes the electromagnet 132 to generate a magnetic force with the same magnetic properties as the toner. This force pushes the toner off the inner wall of the casing 11 through the repulsion of like poles, allowing it to re-enter the cavity inside the casing 11 for collision and crushing. This avoids the phenomenon of toner adhering to the inner wall of the casing 11 and not being fully crushed, thus increasing the crushing speed and making the crushed toner more uniform.

[0020] The outer wall of the outer shell 11 is also provided with several positioning tracks 7 that can cooperate with the repulsion ring 13, which helps to make the positioning of the repulsion ring 13 more accurate when it is pulled up and down, and it is not easy to tilt and affect the smoothness of pulling.

[0021] The bottom of the outer shell 11 is provided with a weighing base 4, which is conducive to monitoring the weight of the fed coarse toner particles through the weighing base 4, and can add material in time when the weight is insufficient.

[0022] The bottom of the repulsion ring 13 is provided with a buffer structure, which includes a silicone block fixedly connected to the bottom of the repulsion ring 13 and a buffer spring 14 set on the bottom surface of the silicone block. This helps to buffer the repulsion ring 13 when it descends to the bottom, and prevent it from directly hitting the feed pipe 2 and the air inlet pipe 3 and causing damage.

[0023] The outer wall of the collar 131 is provided with several handles 135, which makes it easier to pull the collar 131.

[0024] The inner wall of the collar 131 is provided with a sliding block 134 that can cooperate with the positioning track 7, which helps to reduce the frictional resistance when the collar 131 slides, making it easier to pull up and down.

[0025] The inner wall of the collar 131 is also provided with a polished layer 133, which helps to further reduce the frictional resistance when the collar 131 slides up and down, and makes it more wear-resistant and undamaged.

[0026] The working principle of this invention is as follows: In use, coarse toner particles to be crushed are fed into the outer shell 11 through the feed pipe 2. High-pressure air is introduced into the outer shell 11 of the crushing cylinder body 1 through the air inlet pipe 3 on the other side of the outer shell 11. This causes the coarse toner particles fed into the outer shell 11 to be blown by the high-pressure gas, moving within the outer shell 11 and colliding with each other while simultaneously impacting and breaking against the inner wall of the outer shell 11, thus becoming tiny particles. When the particles reach the target size, they can be passed through the classifier 5, and the finished toner is extracted using the extraction device 6. During the collection and crushing process, the repulsion ring 13 can be repeatedly pulled up and down, causing the collar 131 of the repulsion ring 13 to adhere to the outer shell 11 and move up and down. At the same time, current is connected to the power port 136, which causes the electromagnet 132 to generate a magnetic force with the same magnetism as the toner. This force pushes the toner off the inner wall of the outer shell 11 through the repulsion of like poles, allowing it to re-enter the cavity inside the outer shell 11 for collision and crushing. This avoids the phenomenon of toner adhering to the inner wall of the outer shell 11 and not being fully crushed, thus increasing the crushing speed and making the crushed toner more uniform.
