Description

Technical Field

[0001] The present invention relates to the technical field of toner, and particularly relates to a toner crushing and mixing device and a processing method for printing clothing tags. Background Art

[0002] Toner, also known as carbon powder, is a key material used for imaging and fixing on paper in laser printers and copiers. Toner is mainly composed of polymer resin, carbon black or pigments, and at the same time, a part of charge control agents and additives (such as magnetic powder, lubricant, etc.) for adjusting the electrostatic properties of the toner are mixed in, so that the toner can fix the image on the paper during the printing process and form the required image information on the paper. During the production process of clothing tags, it is often necessary to use toner in combination with a printer to print on the initial cardboard of the clothing tag through the toner to form characters and patterns. After the toner adheres to the initial cardboard of the clothing tag, it can be quickly dried and cooled, and has strong adhesiveness, and is not prone to pattern offset under the condition of scratching. The imaging effect is good, and the adhesion firmness is high, so that the clothing tag can maintain a clear display effect for a long time during the transportation following the clothing.

[0003] During the production process of toner for clothing tag printing, the crushing method is usually adopted for processing and production. The crushing method is to mix the raw materials of the toner and perform hot melting to make a variety of toner raw materials melt together to form a toner semi-finished product. Subsequently, the toner semi-finished product is sent into a crushing and mixing device for crushing to make it into micron-sized particles. The crushing and mixing device can crush the fed toner semi-finished product into small particles through a first crushing device, and after extracting the small particles, the small particle toner semi-finished product is finally crushed into tiny particles of the appropriate size through a second crushing device. After screening, the finished toner can be obtained.

[0004] Although the above-mentioned prior art can solve the corresponding technical problems, there are still certain defects: when the existing material crushing and mixing device crushes the toner semi-finished product, since the toner semi-finished product contains charge control agents, during the crushing process in the crushing and mixing device, it is very easy for the small particle toner semi-finished product to adhere to the inner cavity of the crushing and mixing device due to its magnetism, resulting in a decrease in the powder output rate. It is necessary to perform secondary cleaning after processing, otherwise it is very easy to cause waste. And the toner after secondary cleaning has not been screened, and the particle size is uneven, and it needs to be sent in for processing again, which affects the processing efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a toner crushing and mixing device and a processing method for printing clothing tags with low waste and small residue amount in view of the defects and deficiencies of the prior art.

[0006] To achieve the above object, the present invention adopts the following technical solutions: A toner crushing and mixing device for printing clothing tags, including a first crushing and mixing device and a second crushing and mixing device arranged on one side of the first crushing and mixing device and interconnected with the first crushing and mixing device. A high-pressure air pump is further provided on one side of the second crushing and mixing device and is interconnected with the second crushing and mixing device.

In the middle section of the suction pipe, a suction machine is embedded, and a cold air interface is provided on the suction machine.

[0009] A further improvement is that: The pushing anti-sticking block includes a thrust outer shell and anti-sticking rollers arranged inside the thrust outer shell whose outer walls fit with the bottom surface of the inner wall of the outer shell. On one side of the outer shell, a push plate is fixedly connected. The top end of the push plate is movably engaged with a swing slope plate extending to the top surface on the other side of the thrust outer shell. On the top surface of the thrust outer shell, an elastic column fixedly connected with the bottom surface of the swing slope plate is provided.

[0010] A further improvement is that: On the inner wall of the thrust outer shell, a support plate is integrally formed. Between the top surface of the support plate and the bottom surface of the swing slope plate, a number of springs are provided.

[0011] A further improvement is that: The anti-sticking roller includes a connecting shaft and a rolling outer shell movably engaged and sleeved on the outer wall of the connecting shaft. On the inner wall of the rolling outer shell, a number of first paddles are provided. On the outer wall of the connecting shaft, a number of swing columns are provided, and on the top of the swing columns, a number of second paddles are provided.

[0012] A further improvement is that: The outer wall of the rolling outer shell is provided with a friction layer.

[0013] A further improvement is that: The second crushing and mixing device includes a grinding cylinder whose bottom inner wall is provided with a number of hemispherical grinding blocks and an air pressure pipe arranged on the bottom side wall of the grinding cylinder and connected to the high-pressure air pump. On the bottom side wall of the grinding cylinder, a feed pipe interconnected with the first crushing and mixing device is also provided. Nozzles facing downwards are provided at the ends of both the air pressure pipe and the feed pipe. On the top of the grinding cylinder, a classifier with a discharge pipe at the top is also provided. In the central position of the grinding cylinder, an exchange plate extending from top to bottom is detachably provided.

[0014] Further improvement is that: the second crushing and mixing device further includes a magnetic force removal ring fixedly installed below the classifier and with the inner wall of the bottom fitting the outer wall of the grinding cylinder. The magnetic force removal ring includes a push-down cylinder fixedly installed on the bottom surface of the classifier and a sleeve arranged at the bottom end of the push-down cylinder with the inner wall fitting the outer wall of the grinding cylinder. A sliding groove is integrally formed on the inner wall of the sleeve. An electromagnet is slidably arranged on the inner wall of the sliding groove. A current interface electrically connected to the electromagnet is further arranged on the outer wall of the sleeve. A suction and pressing column is arranged between one side of the electromagnet and the inner side wall of the sliding groove.

[0015] Further improvement is that: the exchange plate includes a separation plate detachably arranged at the central position of the grinding cylinder and several through holes integrally formed on the inner wall of the separation plate. Several hemispherical impact blocks are staggered on the inner wall of the through holes. Hemispherical guiding blocks are arranged at both the upper and lower ends of the separation plate.

[0016] The present invention also provides a processing method for toner used for printing clothing tags, including the following steps: Step 1: Load the toner semi-finished product into the toner crushing and mixing equipment for printing clothing tags as described above, and start the first crushing and mixing device. Crush the large pieces of toner semi-finished product through the crushing roller group to form large particle toner semi-finished products, and push the large particle toner semi-finished products to the end of the extraction pipe by pushing the anti-sticking block, and connect the high-pressure air pump to the second crushing and mixing device.

[0017] Step 2: Start the extractor on the extraction pipe, and connect the cold air to the cold air interface to extract the large particle toner semi-finished products and send them into the grinding cylinder of the second crushing and mixing device.

[0018] Step 3: Connect the finished product collection device at the position of the discharge pipe of the second mixing and crushing device. After the first crushing and mixing device is started for 10 min - 15 min, start the second crushing and mixing device to start the classifier.

[0019] Step 4: Start the high-pressure air pump, and the starting time is 5 min - 7 min. Pump the high-pressure air flow into the grinding cylinder of the second crushing and mixing device, so that the large particle toner semi-finished products input into the grinding cylinder are impacted by the high-pressure air flow and collide and break with each other to form small particles, and when the particle diameter meets the size requirements, they are pushed by the air flow through the classifier and output from the discharge pipe.

[0020] Step 5: Repeat Step 4 until all the toner semi-finished products are crushed into small particles.

[0021] After adopting the above technical solutions, the beneficial effects of the present invention are: During the first crushing process of the present invention, the lateral cylinder can cooperate with the anti-sticking block to push the crushed particles to the end of the extraction tube, so that the extraction tube can better extract the semi-finished toner powder after the first crushing in batches. At the same time, when the anti-sticking block is pushed to move, the anti-sticking roller inside it will also rotate synchronously, and then intensive vibration is generated through the rotation of the anti-sticking roller, and the vibration is output to the outer shell, so that the semi-finished toner powder attached to the outer shell after the first crushing can be shaken off and fall to the bottom of the outer shell, and pushed by the anti-sticking block to the end of the extraction tube for extraction and then secondary crushing, so that the semi-finished toner powder after the first crushing can be more fully utilized, and it is prevented from being unable to be extracted for secondary crushing due to magnetic attachment to the inside of the outer shell, so that its utilization rate is increased and the waste is reduced.

[0022] When the present invention performs secondary crushing, an electrical signal can be periodically connected to the current interface, thereby making the magnetic removal circle work and causing the push-down cylinder to push the sleeve downward. When the electromagnet in the sleeve receives the electrical signal, it will generate the same magnetism as the toner, thereby causing the toner to be repelled and pushed away from the inner wall of the grinding cylinder. The high-flow gas output by the air pressure tube is used to blow the toner away from the inner wall of the grinding cylinder, so that it can re-enter the grinding cylinder and collide with the inner wall of the grinding cylinder and collide with other toner particles to perform repeated processing until the required diameter size is reached, thereby effectively reducing the toner adhesion on the inner wall of the grinding cylinder and improving the powder output rate.

[0023] When the present invention performs secondary crushing, the toner particles will repeatedly collide with each other between the two sides of the exchange plate and the inner wall of the grinding cylinder along with the airflow, and the exchange plate will shorten the stroke of each toner particle collision, thereby accelerating the toner collision and crushing speed. At the same time, when part of the toner contacts the exchange plate, it will pass through the through hole and collide with the impact blocks staggeredly distributed on the inner wall of the through hole, thereby greatly improving the crushing speed and processing efficiency. At the same time, the shorter crushing time can reduce the toner particles attached to the inner wall of the grinding cylinder, further avoid the attachment amount, and improve the powder output rate.

The pushing anti-sticking block 26 includes a thrust shell 41 and an anti-sticking roller 47 arranged in the thrust shell 41 and whose outer wall is in contact with the bottom surface of the inner wall of the outer shell 21. The anti-sticking roller 47 includes a connecting shaft 471 and a rolling shell 472 movably engaged with the outer wall of the connecting shaft 471. The inner wall of the rolling shell 472 is provided with a plurality of first paddles 474, the outer wall of the connecting shaft 471 is provided with a plurality of swing columns 475, and the top of the swing column 475 is provided with a plurality of second paddles 476. A push plate 43 is fixedly connected to one side of the outer shell 21, and an extension is movably engaged with the top of the push plate 43. The swing ramp 42 to the top surface of the other side of the thrust shell 43 is provided with an elastic column 46 fixedly connected to the bottom surface of the swing ramp 42 on the top surface of the thrust shell 41. When in use, the large block of semi-finished toner is taken out of the outer shell 21 of the first crushing and mixing device 2, and the crushing roller group 22 is started to rotate the crushing roller group 22. At this time, the falling semi-finished toner blocks are crushed and crushed into small particles by the crushing roller group 22. The small-particle semi-finished toner will fall downward and fall on the bottom surface of the inner wall of the outer shell 21. At this time, the lateral cylinder 25 is repeatedly extended and retracted, thereby causing the push anti-sticking block 26 to repeatedly move horizontally, and then the thrust shell 41 drives the push plate 43 to push the small-particle semi-finished toner that falls on the bottom surface of the inner wall of the outer shell 21 to the end of the extraction tube 27.At this time, the small-particle toner semi-finished product can be extracted and pumped into the second crushing and mixing device 3 for refining processing through the extraction pipe 27. While the lateral cylinder 25 pushes the anti-sticking block 26 to move, the outer surface of the anti-sticking roller 47 arranged at the bottom of the inner wall of the thrust shell 41 will also slide against the bottom surface of the inner wall of the outer shell 21 at the same time. At this time, the rolling shell 472 can be rotated relative to the connecting shaft 471 through the surface friction force. The inner wall of the rolling shell 472 is provided with a plurality of first paddles 474, and the outer wall of the connecting shaft 471 is provided with a plurality of swing columns 475. The end of the swing column 475 is also provided with a plurality of second paddles 476. At this time, the first paddle 474 and the second The paddles 476 generate periodic collisions as the rolling shell 472 rotates, and the paddles 476 contact and paddle each other to generate vibrations, and output the vibrations to the outer shell 21, so that the semi-finished toner powder attached to the outer shell 21 after the first crushing can be shaken off and fall to the bottom of the outer shell 21, and pushed to the end of the extraction tube 27 by the push plate 43 of the anti-sticking block 26 for extraction. The semi-finished toner powder after the first crushing has relatively coarse particles and a large gravity, and is easy to fall off, so that the semi-finished toner powder after the first crushing can be more fully utilized, and it is prevented from being unable to be extracted for secondary crushing due to magnetic attachment to the inside of the outer shell 21, so that its utilization rate is increased and the waste is reduced; After the first crushing and mixing device 2 has been initially crushed, the small-particle semi-finished toner can be drawn into the second crushing and mixing device 3 through the extraction pipe 27, and the semi-finished toner can be pumped into the grinding cylinder 31 through the feeding pipe 36. At the same time, the high-pressure pump air machine 4 outputs high-pressure air and pumps the high-pressure air into the grinding cylinder 31 from the air pressure pipe 35, thereby allowing the high-pressure air to push the semi-finished toner to move at high speed in the grinding cylinder 31, so that the toner can collide with the inner wall of the grinding cylinder 31, and at the same time, the toner can collide with each other, thereby breaking the toner particles into smaller particles. When the particle size meets the requirements, the toner can be screened by the classifier 32, passed through the classifier 32 and extracted by the discharge pipe 34, and the finished toner can be obtained. During the secondary crushing, the toner particles will repeatedly collide with each other along with the airflow between the two sides of the exchange plate 40 and the inner wall of the grinding cylinder 31, and the exchange plate 40 will shorten the stroke of each toner particle collision, thereby accelerating the toner collision crushing speed. At the same time, when part of the toner contacts the exchange plate 40, it will pass through the through hole 403 and collide with the impact block 404 staggeredly distributed on the inner wall of the through hole 403, thereby greatly increasing the crushing speed and improving the processing efficiency. At the same time, the toner particles attached to the inner wall of the grinding cylinder 31 are reduced by a shorter crushing time, further avoiding the amount of attachment and improving the powder yield. The bottom surfaces of the first crushing and mixing device 2 and the second crushing and mixing device 3 are provided with a flat chassis 1, which is beneficial to keeping the first crushing and mixing device 2 and the second crushing and mixing device 3 at the same height, making the bottom more stable and not easily shaking during processing, and enabling the semi-finished granular toner to be better fed into the second crushing and mixing device 3 after being crushed by the first crushing and mixing device 2; On one side of the top of the outer shell 21, there is also an inclined feed pipe 23. Above the lateral cylinder 25 on the inner wall of the outer shell 21, there is a guide plate 24. In the middle section of the extraction pipe 27, there is an extractor 28 embedded. The extractor 28 is provided with a cold air interface, which is beneficial for more convenient feeding. At the same time, the guide plate 24 can better guide the semi-finished granular toner to avoid jamming into the lateral cylinder 25. When extracting the semi-finished granular toner, cold air is introduced through the cold air interface to make the temperature lower during transmission, thereby making the particulate matter more stable and preventing heat melting due to too high temperature from affecting the transmission effect; On the inner wall of the thrust housing 41, there is also an integrally formed support plate 44. Between the top surface of the support plate 44 and the bottom surface of the swing slope plate 42, there are several springs 45, which is beneficial to making the swing slope plate 42 more strongly supported and better generating swings to obtain a larger swing amplitude to shake off the semi-finished granular toner; The outer wall of the rolling housing 472 is provided with a friction layer 477, which is beneficial to increasing the friction force during contact, thereby enabling the rolling housing 472 to rotate more quickly; The second crushing and mixing device 3 further includes a magnetic force removal ring 39 fixedly installed below the classifier 32 and with the inner wall of the bottom fitting the outer wall of the grinding cylinder 31. The magnetic force removal ring 39 includes a push-down cylinder 391 fixedly installed on the bottom surface of the classifier 32 and a sleeve 392 arranged at the bottom end of the push-down cylinder 391 with the inner wall fitting the outer wall of the grinding cylinder 31. An integral sliding groove 393 is formed on the inner wall of the sleeve 392. An electromagnet 395 is slidably arranged on the inner wall of the sliding groove 393. A current interface 396 electrically connected to the electromagnet 395 is further arranged on the outer wall of the sleeve 392. A suction and pressure column 394 is arranged between one side of the electromagnet 395 and the inner side wall of the sliding groove 393. When current is input, it can buffer the suddenly generated strong magnetic force of the electromagnet 395, thereby preventing the electromagnet 395 from being pushed to impact the inner wall of the sliding groove 393 and causing damage. When performing secondary crushing, an electrical signal can be periodically connected to the current interface 396, so that the magnetic force removal ring 39 works, and the push-down cylinder 391 pushes the sleeve 392 to move downward. When the electromagnet 395 in the sleeve 392 receives the electrical signal, it will generate the same magnetism as the toner, so that the toner is repelled and pushed away from the inner wall of the grinding cylinder 31. Cooperating with the high-velocity gas output by the pneumatic tube 35, the toner is blown away from the inner wall of the grinding cylinder 31, so that it can re-enter the grinding cylinder 31 and be repeatedly processed by colliding with the inner wall of the grinding cylinder 31 and colliding with other toner particles until it reaches the required diameter size, thereby effectively reducing the adhesion of the toner on the inner wall of the grinding cylinder 31 and improving the powder output rate.

[0028] The present invention also provides a processing method for toner used for printing clothing tags, including the following steps: Step 1: Load the toner semi-finished product into the toner crushing and mixing equipment for printing clothing tags as described above, and start the first crushing and mixing device 2. The large-piece toner semi-finished product is crushed by the crushing roller group 22 to form large-particle toner semi-finished products, and the large-particle toner semi-finished products are pushed to the end of the extraction tube 27 by the push anti-sticking block 26, and the high-pressure air pump 4 is connected to the second crushing and mixing device 3.

[0029] Step 2: Start the extractor 28 on the extraction tube 27, and connect cold air to the cold air interface to extract the large-particle toner semi-finished products and send them into the grinding cylinder 31 of the second crushing and mixing device 3.

[0030] Step 3: Connect a finished product collection device at the position of the discharge pipe 34 of the second mixing and crushing device 3. After the first crushing and mixing device 2 is started for 10 min - 15 min, start the second crushing and mixing device 3 to start the classifier 32.

[0031] Step 4: Start the high-pressure air pump 4 for 5 to 7 minutes, and pump high-pressure air into the grinding cylinder 31 of the second crushing and mixing device 3, so that the large-particle toner semi-finished products input into the grinding cylinder 31 are impacted by the high-pressure air flow and collide with each other to break into small particles, and when the particle diameter meets the size requirements, they are pushed by the air flow through the classifier 32 and output from the discharge pipe 34.

[0032] Step 5: Repeat Step 4 until all the toner semi-finished products are crushed into small particles.

[0033] Working principle of the present invention: When the present invention is in use, the large-piece toner semi-finished products are placed into the outer shell 21 of the first crushing and mixing device 2, and the crushing roller set 22 is started to rotate the crushing roller set 22. At this time, the dropped toner semi-finished product blocks can be crushed by the crushing roller set 22 into small particles. The small-particle toner semi-finished products will fall downward and land on the bottom surface of the inner wall of the outer shell 21. At this time, the lateral cylinder 25 generates repeated telescoping, which in turn causes the anti-sticking block 26 to move horizontally repeatedly, and then drives the push plate 43 through the thrust outer shell 41 to push the small-particle toner semi-finished products on the bottom surface of the inner wall of the outer shell 21 to the end of the extraction pipe 27. At this time, the small-particle toner semi-finished products can be pumped into the second crushing and mixing device 3 through the extraction pipe 27 for refinement. While the lateral cylinder 25 pushes the anti-sticking block 26 to move, the outer surface of the anti-sticking roller 47 provided at the bottom of the inner wall of the thrust outer shell 41 also slides along the bottom surface of the inner wall of the outer shell 21 at the same time. At this time, the rolling outer shell 472 can rotate relative to the connecting shaft 471 through surface friction. There are several first paddles 474 on the inner wall of the rolling outer shell 472, and several swing columns 475 are provided on the outer wall of the connecting shaft 471. There are also several second paddles 476 at the end of the swing column 475. At this time, the first paddles 474 and the second paddles 476 can collide periodically as the rolling outer shell 472 rotates, and contact and push each other to generate vibration, and output the vibration to the outer shell 21, so that the toner semi-finished products after the first crushing attached to the inner shell 21 can be shaken and fall to the bottom of the outer shell 21, and are pushed by the push plate 43 of the anti-sticking block 26 to the end of the extraction pipe 27 for extraction. The toner semi-finished products after the first crushing have relatively large and heavy particles and are easy to fall off. Therefore, the toner semi-finished products after the first crushing can be more fully utilized, preventing them from being magnetically attached to the inside of the outer shell 21 and unable to be extracted for secondary crushing, increasing their utilization rate and reducing waste. After the first crushing and mixing device 2 performs preliminary crushing, at this time, the semi-finished product of small-particle toner can be pumped into the second crushing and mixing device 3 through the extraction pipe 27, and the semi-finished product of toner can be pumped into the grinding cylinder 31 through the feeding pipe 36. At the same time, high-pressure air is output through the high-pressure air pump 4 and pumped into the grinding cylinder 31 from the air pressure pipe 35, so as to make the high-pressure air push the semi-finished product of toner move at high speed in the grinding cylinder 31, enabling the toner to collide with the inner wall of the grinding cylinder 31, and at the same time enabling the toner to collide with each other, so that the toner particles are broken into smaller particles. When the particle size meets the requirements, at this time, the toner can be screened by the classifier 32, pass through the classifier 32 and be extracted by the discharge pipe 34, and at this time, the finished toner can be obtained; When performing secondary crushing, the toner particles will repeatedly collide with each other between the two sides of the exchange plate 40 and the inner wall of the grinding cylinder 31 along with the airflow. By means of the exchange plate 40, the travel of each toner particle collision is reduced, thereby accelerating the collision and pulverization speed of the toner. At the same time, when part of the toner contacts the exchange plate 40, it passes through the through hole 403 and collides with the impact blocks 404 distributed in a staggered manner with the inner wall of the through hole 403, thereby greatly increasing the pulverization speed, improving the processing efficiency, and at the same time reducing the toner particles attached to the inner wall of the grinding cylinder 31 through a shorter pulverization time, further avoiding the adhesion amount and increasing the powder output rate.
