Description

Technical Field

[0001] The invention relates to the technical field of carbon powder, and in particular to a high-efficiency mixer for processing carbon powder. Background Art

[0002] Toner, also known as toner, is a printing consumable used in laser printers. It has the appearance of powder particles and is mainly formed by crushing and evenly mixing resins, pigments and additives. Its production process is relatively simple: the mixer first mechanically crushes and mixes various raw materials, and then melts them at high temperature. After cooling and solidifying, the melt is mechanically crushed and then classified according to particle size. Among them, when the mixer processes toner, it first needs to mechanically crush and mix various raw materials. The mixed mixture enters the melting device through the screw feeder at the bottom of the feed port. Since the processing of toner needs to be continuous, the feed port needs to be It is necessary to ensure the appropriate mixing ratio of raw materials and the unlimited mixing uniformity; in the prior art, the design of the feeding part of the mixer is relatively backward, and its mixing efficiency still cannot be qualitatively improved. Due to the different properties of various raw materials, their respective crushing times are different. The prior art mainly increases the mixing crushing time and adds interception means (screens) to improve the crushing effect to achieve the purpose of improving the mixing efficiency. However, this method easily causes stratification between the raw materials, and the gaps between them will be larger, which is not conducive to the effective mixing of the raw materials. Therefore, this interception method not only reduces the mixing efficiency of the device, but also destroys the ratio between the raw materials. Therefore, it is urgent to solve it.

[0014] The working principle and beneficial effects of the present invention are: 1. This device redesigns the feed module of the mixer, which greatly improves the cutting and mixing efficiency of the device. A "mixing zone" with variable volume is formed by setting arc plate 1, arc plate 2 and a rotating plate supported by an elastic support component. Two sets of cutting components, one long and one short, installed on the outer surface of the motor and the connecting sleeve are provided, and the raw material mixture entering the "mixing zone" is cut in cooperation with cutter 2 and cutter 3. When the motor drives the longer set of cutting components on the left side to move, since the left side of the "mixing zone" with an annular structure is fixed, when the limiting roller rotates and abuts, the entire arc plate 1 will expand outward and drive the arc plate 2 to expand to increase the volume of the "mixing zone". The arc plate is hinged to the connecting plate by a connecting frame, a support rod and a clamping column. While moving to the right, arc plate 1 and arc plate 2 drive the support rod to rotate and adapt. At this time, due to the rotation of the support rod, one end of the support rod that is clamped in the slide slot begins to move toward one side of compression spring 2, so that arc plate 2 has a reset function. When the motor drives the cutting assembly to rotate 180°, the expansion of arc plate 1 and arc plate 2 reaches the maximum, that is, the volume of the "mixing zone" reaches the maximum. Then, as the motor drives the cutting assembly to continue to rotate, arc plate 1 and arc plate 2 begin to recover and gradually reduce the "mixing zone". This design allows the raw materials entering the "mixing zone" to be fully squeezed and tumbled, and the volume change rate of the "mixing zone" is related to the speed of the motor. Therefore, the raw material mixture can be fully mixed here, thereby greatly improving the cutting and mixing efficiency of the device.

[0015] 2. The device is also designed with a cutting assembly including a connecting sleeve, a connecting column, a movable sleeve, a cutter 1, a limiting frame, a limiting roller and a cutter 2. The cutting assembly is divided into two groups, long and short. The limiting roller abuts against the inner walls of the arc plate 1 and the arc plate 2, so that the cutter 2 installed on both sides of the limiting frame can always maintain a safe distance from the inner walls of the arc plate 1 and the arc plate 2, and at the same time, no dead angle for cutting is generated. The raw material mixture in the "mixing zone" is cut by providing a movable sleeve and a pair of cutters that are perpendicular to the radial direction of the connecting sleeve and can rotate around the radial direction of the connecting sleeve. When the movable sleeve and the cutter 1 are driven to revolve by the motor and the connecting sleeve, the part of the cutter 1 that is in a horizontal state is used to cut the raw material. At the same time, the movable sleeve and the cutter 1 are limited by the raw material during the revolution, resulting in rotation, and the raw material mixture is passively rolled, so that the raw material is always kept in a moving state when being cut, which is helpful to mix the mixture and improve the cutting efficiency.

[0016] 3. The device realizes the automatic control function of the material discharge speed by providing an elastic support component and a rotating plate, directly avoiding the energy waste caused by the idling of the motor and the cutting component. A support cylinder is installed on the top of a bottom plate, and a telescopic column is elastically installed inside the support cylinder through a spring. A fixed plate is fixedly installed through the top of the telescopic column, so that the rotating plate can be rotatably installed on the top of the fixed plate through a bearing. When the raw material mixture in the "mixing zone" (i.e., the space formed by the top of the rotating plate and the arc plate 1 and the arc plate 2) increases and its own weight increases, and is greater than the supporting elastic force of the spring 1, the rotating plate automatically moves down and forms a "material discharge gap" with the arc plate 1 and the arc plate 2, and then the high-speed rotating rotating plate generates a centrifugal effect to "throw" the material out. As the material in the "mixing zone" decreases, its own weight decreases, and the rotating plate automatically rises under the action of the spring 1, thereby reducing or even closing the "material discharge gap", thereby achieving the control of the material discharge speed and ensuring that the cutting component can always act on the material.

A sliding groove 25 that penetrates backward is opened in the middle of the connecting plate 24. The upper and lower sides of the inner wall of the sliding groove 25 are movably connected with a card column 23. The support rod 22 is movably hinged with the connecting plate 24 through the card column 23. The upper and lower sides of the inner wall of the sliding groove 25 are movably connected with a card block 27 that abuts against the support rod 22. A spring 26 is elastically connected between the two groups of card blocks 27. A connecting strip 28 is fixedly connected to the left side of the connecting plate 24. An arc plate 29 is fixedly connected to the left side of the connecting strip 28. Grooves are opened on both sides of the arc plate 29 and are adapted to be clamped with both sides of the arc plate 1 20. The bottoms of the arc plates 1 20 and 29 abut against the top of the rotating plate 17. The two groups of cutting components abut against the inner walls of the arc plates 1 20 and 29 respectively. A cutter 3 30 is fixedly connected to the bottom of the outer surface of the connecting sleeve 5. The device redesigns the feed module of the mixer, which greatly improves the cutting and mixing efficiency of the device. A "mixing zone" with variable volume is formed by providing an arc plate 1 20, an arc plate 2 29 and a rotating plate 17 supported by an elastic support component. Two groups of cutting components, one long and one short, installed on the outer surface of the motor 4 and the connecting sleeve 5 are provided, and the raw material mixture entering the "mixing zone" is cut in cooperation with the cutter 2 10 and the cutter 3 30. When the motor 4 drives the longer group of cutting components on the left side to move, since the left side of the "mixing zone" of the circular ring structure is fixed, when the limiting roller 91 rotates and abuts, the entire arc plate 1 20 will expand outward and drive the arc plate 29 to expand to increase the volume of the "mixing zone". The connecting frame 21, the support rod 22 and the clamping column 23 are hinged with the connecting plate 24 to make the arc plate 20 expand outward. When plate 29 moves to the right, it drives the support rod 22 to rotate and adapt. At this time, due to the rotation of the support rod 22, one end of the support rod 22 that is clamped in the slide slot 25 begins to move toward the side of the compression spring 26, so that arc plate 29 has a reset function. When the motor 4 drives the cutting assembly to rotate 180°, the expansion of arc plate 1 20 and arc plate 2 29 reaches the maximum, that is, the volume of the "mixing zone" reaches the maximum. Then, as the motor 4 drives the cutting assembly to continue to rotate, arc plate 1 20 and arc plate 2 29 begin to recover and gradually reduce the "mixing zone". This design allows the raw materials entering the "mixing zone" to be fully squeezed and tumbled, and the volume change rate of the "mixing zone" is related to the rotation speed of the motor 4. Therefore, the raw material mixture can be fully mixed here, thereby greatly improving the cutting and mixing efficiency of the device.

[0022] Embodiment 2: A spiral assembly is provided inside the screw feeder 1 and is communicated with the bottom opening of the feed barrel 2.

A movable sleeve 7 is rotatably installed on the outer surface of the connecting column 6. Four groups of cutters 8 equidistantly distributed in a circle are fixedly connected to the outer surface of the movable sleeve 7. One end of the connecting column 6 is fixedly connected to a limiting frame 9. A limiting roller 91 is rotatably installed inside the limiting frame 9. Cutters 10 are fixedly connected to both sides of the limiting frame 9. One group of connecting columns 6 on the left side is longer than the other group of connecting columns 6. One group of limiting rollers 91 on the left side abuts against the middle part of the inner wall of the arc plate 1 20, and the other group of limiting rollers 91 abuts against the middle part of the inner wall of the arc plate 29. The device is also designed with a cutting assembly including a connecting sleeve 5, a connecting column 6, a movable sleeve 7, a cutter 1 8, a limiting frame 9, a limiting roller 91 and a cutter 2 10. The cutting assembly is divided into two groups, long and short. The limiting roller 91 abuts against the inner walls of the arc plate 1 20 and the arc plate 2 29, so that the cutter 2 10 installed on both sides of the limiting frame 9 can always maintain a safe distance from the inner walls of the arc plate 1 20 and the arc plate 2 29, while not generating a dead angle for cutting. By providing a radially perpendicular to the connecting sleeve 5 and being able to go around the radial direction of the connecting sleeve 5, the cutting assembly is divided into two groups, long and short. The rotating movable sleeve 7 and the cutter 8 cut the raw material mixture in the "mixing area". When the movable sleeve 7 and the cutter 8 are driven to revolve by the motor 4 and the connecting sleeve 5, the raw materials are cut by the horizontal part of the cutter 8. At the same time, the movable sleeve 7 and the cutter 8 are limited by the raw materials during the revolution, causing rotation, and passively rolling the raw material mixture, so that the raw material is always kept in a moving state when being cut, which is helpful to mix the mixture and improve the cutting efficiency.

[0023] Embodiment 3: The elastic support assembly includes a bottom plate 12 fixedly connected to one end of the support frame 11, four groups of circumferentially equidistantly distributed support cylinders 13 are fixedly installed on the top of the bottom plate 12, and the inside of the support cylinder 13 is movably sleeved with a spring 15 and a telescopic column 14 in sequence from bottom to top, and the top of the telescopic column 14 is fixedly connected with a fixed plate 16, and a rotating plate 17 is rotatably installed on the top of the fixed plate 16. The fixed plate 16 and the rotating plate 17 are both movably sleeved on the output shaft of the motor 4, and the telescopic column 14 is elastically supported in the support cylinder 13 through the spring 15; The device realizes the automatic control function of the material feeding speed by providing an elastic support component and a rotating plate 17, directly avoiding the energy waste caused by the idling of the motor 4 and the cutting component. The bottom plate 12 is provided with a support cylinder 13 installed on the top thereof, the interior of the support cylinder 13 is elastically installed with a telescopic column 14 through a spring 15, and a fixed plate 16 is fixedly installed through the top of the telescopic column 14, so that the rotating plate 17 can be rotatably installed on the top of the fixed plate 16 through a bearing. When the "mixing area" (i.e., the top of the rotating plate 17 and the arc plate 1 20, the arc plate 29) are in a state of rotation, the rotating plate 17 can rotate and rotate on the top of the fixed plate 16. When the "mixing area" (i.e., the top of the rotating plate 17 and the arc plate 1 20, the arc plate 29) are in a state of rotation, the rotating plate 17 can rotate and rotate on the top of the fixed plate 16. When the rotating plate 17 is ... When the raw material mixture in the space formed by the mixing area increases and its own weight increases, and is greater than the supporting elastic force of the spring 15, the rotating plate 17 automatically moves down and forms a "feeding gap" with the arc plate 1 20 and the arc plate 2 29, and then the high-speed rotating rotating plate 17 produces a centrifugal effect to "throw" the material out. As the material in the "mixing area" decreases, its own weight decreases, and the rotating plate 17 automatically rises under the action of the spring 15, thereby reducing or even closing the "feeding gap", thereby achieving the control of the feeding speed and ensuring that the cutting component can always act on the material.

[0024] Embodiment 4: The arc plate 1 20 and the arc plate 2 29 are both made of stainless steel, and the arc plate 1 20 and the arc plate 2 29 are combined to form a circular ring structure whose center is located on the left side of the axis of the motor 4; Arc plate 1 20 and arc plate 2 29 are made of stainless steel, which has the advantages of smooth surface, corrosion resistance, low cost, easy manufacturing and acquisition. The entire circular ring structure is eccentrically set, and its axis is located on the left side of the axis of motor 4. When motor 4 drives a longer set of cutting components to move, arc plate 1 20 and arc plate 2 29 will be squeezed and expanded.

[0025] Embodiment 5: A group of connecting frames 21 located on the upper side is fixedly connected to the right side of the top of the inner wall of the feed barrel 2, and another group of connecting frames 21 is fixedly connected to the right side of the inner wall of the feed barrel 2; The connecting frame 21 provides hinged support for the support rod 22, so that the other end of the support rod 22 can slide and support the connecting plate 24 through the clamping column 23, so that the arc plate 29 can be restored to the original state and original position.

[0026] Embodiment 6: The middle part of the support rod 22 is hollowed out so that the connecting plate 24 can enter therein, and the upper and lower groups of support rods 22 are symmetrically distributed; When the motor 4 drives the cutting assembly to rotate, and causes the arc plate 29 to expand outward and move to the right at the same time, the arc plate 29 and the connecting plate 24 are driven to move to the right. At this time, the connecting plate 24 can fit through the hollow area of ​​the support rod 22 to avoid jamming.

[0027] Embodiment 7: The connecting head 19 and the connecting strip 28 are both made of rubber blocks and are fixedly connected to the middle of the outer surface of the arc plate 1 20 and the arc plate 2 29 respectively; The connecting head 19 and the arc plate 29 are used to connect the fixed column 18 and the arc plate 1 20, the connecting plate 24 and the arc plate 29. When the arc plate 1 20 and the arc plate 29 are squeezed and expand and displaced (only the arc plate 29 can displace), the connecting head 19 and the connecting strip 28 can provide a flexible connection to avoid metal fatigue consumption caused by the rigid connection between the fixed column 18 and the arc plate 1 20, the connecting plate 24 and the arc plate 29.

[0028] Embodiment 8: The connecting plate 24 and the connecting strip 28 are shorter than the second arc plate 29 and are located in the middle of the outer surface of the second arc plate 29; There is a gap between the connecting strip 28 and the connecting plate 24 and the fixing plate 16 , so that when the fixing plate 16 rotates, no wear will occur on the connecting plate 24 and the connecting strip 28 .

[0029] Embodiment 9: A collection frame 31 is fixedly installed on the left side of the top of the inner wall of the feed barrel 2, and the collection frame 31 is just vertically opposite to the two groups of feed ports 3; The collecting frame 31 is responsible for guiding the materials from the feed port 3 so that the raw materials accurately enter the "mixing area".

[0030] Embodiment 10: The rotating plate 17 is fixedly connected to the output shaft of the motor 4, and the upper surface area of ​​the rotating plate 17 is larger than the area of ​​the circular ring structure formed between the arc plate 1 20 and the arc plate 2 29; The rotating plate 17 can rotate along with the output shaft of the motor 4. When the "material unloading gap" is opened, the high-speed rotating rotating plate 17 can centrifugally throw out the material on its upper surface, thereby achieving a smooth material unloading function.

[0031] Working principle: First, start the motor 4 and drive the cutting assembly to rotate in a clockwise direction. When the long group of cutting assemblies rotates, the limiting rollers 91 therein are always in contact with the inner walls of the arc plate 1 20 and the arc plate 2 29. This is because the distance between the axis of the motor 4 and the outer surface of the limiting rollers 91 on the left is greater than or equal to the distance between the axis of the motor 4 and the inner wall of the arc plate 1 20 or the arc plate 2 29. At this time, the arc plate 1 20 begins to be contacted by the limiting rollers 91 on the left and begins to expand outward and deform. Since the position of the cutter 2 10 is fixed, the two sides of the arc plate 1 20 that expand outward will gradually separate from the arc plate in a symmetrical manner. In the grooves on both sides of the second arc plate 29, at this time, the arc plate 29 starts to move to the right and expand outward at the same time, and pushes the connecting strip 28 and the connecting plate 24. At this time, the upper and lower groups of support rods 22 rotate around the axis of the connecting frame 21 under the action of the connecting plate 24, and push the block 27 along the inner wall of the slide groove 25 to move toward each other. At the same time, the spring 26 is compressed. At this time, the volume of the "mixing zone" of the annular structure formed by the combination of the arc plate 1 20 and the arc plate 29 gradually increases until the cutting assembly rotates to the position of 180°, and the volume of the "mixing zone" is the largest. Subsequently, when the cutting assembly continues to rotate with the motor 4, the volume of the "mixing zone" gradually decreases; Then, the raw materials are poured into the "mixing zone" along the feed port 3. The raw material mixture is supported by the rotating plate 17 and gradually accumulated in the "mixing zone". The rotating plate 17 is kept in contact with the arc plate 1 20 and the arc plate 2 29 under the elastic force of the spring 15 to prevent the raw materials from leaking. When the motor 4 drives the cutting assembly to rotate, the cutter 2 10 and the cutter 3 30 directly rotate and cut the raw material mixture. Subsequently, the movable sleeve 7 and the cutter 1 8 are restricted by the raw material mixture and rotate themselves during the rotation process. The horizontal distribution side of the cutter 1 8 starts to cut and mix the raw material mixture. After the motor 4 drives the cutting assembly to rotate one circle, the volume of the "mixing zone" gradually increases, then gradually decreases and returns to the initial state, thereby extruding the raw material mixture and rearranging the material stack. Finally, when the raw materials from the feed port 3 continue to enter the "mixing zone", the weight of the raw material mixture gradually increases. At this time, the spring 15 supporting the rotating plate 17 begins to be compressed and shrinks downward, so that a "discharging gap" is generated between the bottom of the arc plate 1 20, the arc plate 2 29 and the rotating plate 17, causing the raw material mixture that has been cut and mixed at the bottom layer to leak outward. At the same time, the rotating plate 17 rotating with the motor 4 drives the raw material mixture to "swing" outward with the centrifugal force generated on its upper surface to assist in material discharge. When the raw material mixture in the "mixing zone" is reduced due to material discharge, the elastic force generated by the spring 15 is greater than the gravity of the raw material mixture again, thereby driving the rotating plate 17 to move upward and block the "discharging gap", thereby realizing automatic adjustment of the discharging speed.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
