Description

Technical Field

[0001] This invention belongs to the field of raw material grinding technology, specifically a raw material grinding device for preparing high-elasticity hot melt adhesive labels. Background Technology

[0002] High-elasticity hot melt adhesive labels are flexible label materials with hot melt adhesive as the base material. The core raw materials of high-elasticity hot melt adhesive labels usually need to be ground during processing to obtain raw materials with the required particle size. The most common method is wet grinding with a sand mill.

[0003] In existing technologies, grinding devices for raw materials used in the preparation of high-elasticity hot melt adhesive labels typically employ a sand mill for wet grinding. The materials are mixed with a solution, and grinding beads are placed into the mill cylinder for agitation. However, during actual agitation grinding, the grinding balls move in a relatively fixed direction within the grinding chamber, rotating circumferentially along the agitation direction. When shearing and grinding, the unidirectional direction results in generally low grinding intensity. Furthermore, the grinding process involves collisions with the dispersion disc, causing significant impact damage and noise, leading to poor overall grinding performance. Summary of the Invention

[0017] (3) By reusing the rotating guide sleeve, the air supply component and the reversing component, and the purge port on the outside of the rotating guide sleeve, after the material discharge inside the grinding cylinder is completed, the reversing component is activated to open the purge port and seal the side port one, so as to realize the bypass purge of the gas introduced into the rotating guide sleeve, and to perform rotational purge of the inside of the grinding cylinder during the rotation process, so as to achieve internal drying and purge cleaning. No additional special equipment is required, and the self-cleaning treatment after grinding can be quickly achieved. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 10 As shown, this embodiment of the invention provides a raw material grinding device for preparing high-elasticity hot melt adhesive labels, including a grinding cylinder 1. A rotating guide sleeve 4 is rotatably installed inside the grinding cylinder 1. Dispersion disks 5 are evenly distributed in an array on the outer side of the rotating guide sleeve 4. An elastic processing component 6 is fixedly provided on the outer side of the dispersion disks 5. An elastic inner cylinder 7 is fixedly sleeved on the inner wall of the grinding cylinder 1. A power component 8 and an air supply component 9 are respectively provided at the outer end of the grinding cylinder 1. Grinding beads are provided inside the grinding cylinder 1. The air supply component 9 is connected to the rotating guide sleeve 4. The rotating guide sleeve 4 is connected to the interior of the elastic processing component 6 through the dispersion disks 5. The air supply component 9 controls the intermittent expansion of the elastic processing component 6 through the rotating guide sleeve 4. The elastic processing component 6 includes an elastic pad 61, a fixing frame 62, an elastic sleeve frame 63, and a connecting port 64. The elastic pad 61 is symmetrically fixed on both sides of the dispersion disk 5. The fixing frame 62 is fixedly connected to both sides of the dispersion disk 5. The elastic sleeve frame 63 is fixedly sleeved on the outer side of the fixing frame 62 and is connected to the interior of the fixing frame 62 through the connecting port 64.

[0022] Example 1: In use, the grinding beads and the mixed raw materials to be ground are fed into the interior of the grinding cylinder 1 through the feed pipe 2 on the side of the grinding cylinder 1. The power assembly 8 is started, and the motor 81 drives the gear 1 82 to rotate, which in turn drives the meshing gear 2 83 to rotate, causing the sleeved rotating conduction sleeve 4 to rotate. This drives the dispersing disc 5 in the grinding cylinder 1 to rotate. The dispersing disc 5, in conjunction with the outer elastic processing component 6, rotates and stirs the mixed materials in the grinding cylinder 1, and drives the grinding beads to move at high speed. The grinding beads collide and rub strongly with the materials, thereby refining and grinding the materials. As the high-speed moving grinding beads collide with the surface of the elastic processing component 6, they repeatedly move under the impact and elastic action. At the same time, the air supply assembly 9 is started, and the air pump 91 delivers pressurized air through the curved pipe 93, the solenoid valve 94, and the sleeve 92. The material is fed into the rotating guide sleeve 4 and input into the fixed frame 62 through the middle port 102, side port 12, annular groove 53 and connecting cavity 52. ​​Pressurized air is input into the elastic sleeve 63 through the connecting port 64, causing the elastic sleeve 63 to inflate and expand. During rapid expansion, the elastic sleeve 63 impacts and pushes the contacting grinding beads, causing the grinding beads to accelerate. The control solenoid valve 94 is intermittently activated, causing the elastic sleeve 63 to reciprocate rapidly expanding, deforming and contracting, completing the intermittent ejection of the grinding group. The direction and speed of the grinding beads in the sand grinding cylinder 1 are changed, and the material is ground and refined more thoroughly. During the rotating grinding process, the rotating guide sleeve 4 drives the cleaning component 11 to rotate rapidly. The cleaning component 11 rotates along the inside of the filter discharge section 3 and performs friction cleaning on the filter holes 33, completing the synchronous unclogging treatment.

[0023] First, by utilizing the power component 8, air supply component 9, rotating guide sleeve 4, dispersing disc 5, and elastic processing component 6, during the wet grinding of raw materials, on the one hand, the rotating dispersing disc 5 and elastic processing component 6 work together to agitate the grinding beads in the grinding cylinder 1 at high speed. The high-speed movement of the grinding beads under agitation effect shears and crushes the raw material particles in the mixture liquid. On the other hand, through the intermittent air supply of the air supply component 9, the elastic processing component 6 is intermittently inflated and expanded. The intermittently inflated elastic sleeve 63 provides an elastic force to the contacting grinding beads, accelerating the rapid movement of the grinding beads in different directions. While providing movement speed, it also increases the complexity of movement directions, thereby improving the grinding effect on the material and avoiding the poor shearing and grinding effect in a single direction, thus greatly improving the grinding efficiency.

[0024] Furthermore, by utilizing the combined action of the elastic processing component 6 and the elastic inner cylinder 7, during high-speed grinding under agitation, the high-speed grinding balls repeatedly contact the elastic processing component 6 and the inner wall of the elastic inner cylinder 7 during the impact and collision process, accelerating the rebound while reducing the noise under rigid collision and lowering the grinding noise.

[0025] Example 2: After the grinding process is completed, as the material and grinding beads in the grinding cylinder 1 are discharged, the air supply component 9 is kept ventilated, so that pressurized air is input into the rotating guide sleeve 4. The reversing component 10 is activated, the electric push rod 103 is activated and drives the inner tube 101 to move, so that the middle port 102 is offset from the side port 12, and after moving, it is connected to the blowing port 13, and is blown out through the blowing port 13. As the power component 8 drives the rotating guide sleeve 4 to rotate, the blowing port 13 rotates and blows along the inside of the grinding cylinder 1, completing the internal blowing and cleaning, and completing the drying and cleaning process.

[0026] First, by reusing the rotating guide sleeve 4, the air supply component 9, and the reversing component 10, and cooperating with the purge port 13 on the outside of the rotating guide sleeve 4, after the material discharge inside the sand mill cylinder 1 is completed, the reversing component 10 is activated to move, the purge port 13 is opened and the side port 12 is sealed, so as to realize the bypass purging of the gas introduced into the rotating guide sleeve 4, and the interior of the sand mill cylinder 1 is purged during rotation, so as to achieve internal drying and purging cleaning. Without the need for additional special equipment, the self-cleaning treatment after grinding can be quickly achieved.

The sleeve 92 is fitted on the outer end of the rotating guide sleeve 4, and a sealing ring is provided between the sleeve 92 and the rotating guide sleeve 4. One end of the curved pipe 93 is connected to the air outlet end of the air pump 91, and the other end is fixedly connected to the solenoid valve 94. The solenoid valve 94 is fixed on the end face of the sleeve 92.

[0032] The air supply component 9 is used to provide pressurized air to achieve the air expansion of the elastic sleeve 63, and to achieve rapid elastic expansion and recovery under intermittent input, thereby generating an elastic force on the grinding beads through repeated action.

[0033] The power assembly 8 includes a motor 81, a first gear 82, and a second gear 83. The first gear 82 is fixedly connected to the output shaft of the motor 81, and the second gear 83 is fixedly sleeved on the outer surface of the rotating guide sleeve 4. The second gear 83 meshes with the first gear 82, and the power assembly 8 controls the rotation of the rotating guide sleeve 4.

[0034] The power unit 8 provides power to achieve the rotational motion.

[0035] The filter discharge section 3 includes a discharge cylinder 31, a discharge pipe 32, and a filter hole 33. The discharge cylinder 31 is fixedly sleeved on the right end of the grinding cylinder 1, the discharge pipe 32 is fixedly connected to the end face of the discharge cylinder 31, and the filter hole 33 is opened on the outer side of the discharge cylinder 31.

[0036] The filter discharge section 3 performs filtration, allowing ground materials of suitable size and water to pass through.

[0037] Among them, a bearing 14 is fixedly sleeved on the outer side of the inner end of the rotating guide sleeve 4, and one end of the rotating guide sleeve 4 is rotatably installed in the filter discharge section 3 through the bearing. A cleaning component 11 is fixedly provided on one end of the rotating guide sleeve 4, and the cleaning component 11 is located in the discharge cylinder 31.

[0038] The rotating guide sleeve 4 rotates while maintaining the internal gas flow, thus achieving ventilation control.

[0039] The cleaning assembly 11 includes a cleaning arc plate 111 and a connecting rod 112. One end of the connecting rod 112 is fixedly connected to the cleaning arc plate 111, and the other end is fixed on the rotating guide sleeve 4. The outer side of the cleaning arc plate 111 is in contact with the inner wall of the discharge cylinder 31.

[0040] The cleaning component 11, in conjunction with the rotation effect, simultaneously completes the self-cleaning process of the filter discharge section 3, preventing blockages and automatically clearing blockages.

[0041] The rotating guide sleeve 4 is equipped with a reversing assembly 10, which includes an inner tube 101, a middle port 102, and an electric push rod 103. The outer side of the rotating guide sleeve 4 is provided with a purge port 13. The inner tube 101 is movably sleeved in the rotating guide sleeve 4. The middle port 102 is opened on the outer side of the inner tube 101. The purge port 13 is located on the moving path of the middle port 102. The electric push rod 103 is fixed in the rotating guide sleeve 4, and the movable end of the electric push rod 103 is fixedly connected to the inner tube 101 through a connecting block, and controls the inner tube 101 to move laterally in the rotating guide sleeve 4. The side port 12 is located on the moving path of the middle port 102.

[0042] By moving and reversing the reversing component 10, the closed airflow is directed toward the interior of the dispersion disk 5 and directly bypassed along the purging port 13, thus achieving the purging treatment inside the sand mill cylinder 1.

[0043] The working principle and usage process of this invention are as follows: During use, the grinding beads and the mixed raw material to be ground are fed into the interior of the grinding cylinder 1 through the feed pipe 2 on the side of the grinding cylinder 1. The power assembly 8 is started, and the motor 81 drives gear 1 82 to rotate, which in turn drives the meshing gear 2 83 to rotate, causing the sleeved rotating conductive sleeve 4 to rotate. This, in turn, drives the dispersing disc 5 in the grinding cylinder 1 to rotate. The dispersing disc 5, in conjunction with the outer elastic processing assembly 6, rotates and stirs the mixed material in the grinding cylinder 1, and drives the grinding beads to move at high speed. Strong collisions occur between the grinding beads and the material. Friction refines and grinds the material. As the high-speed grinding beads collide with the surface of the elastic processing component 6, they repeatedly move under impact and elasticity. Simultaneously, the air supply component 9 is activated. The air pump 91 inputs pressurized air through the curved pipe 93, solenoid valve 94, and sleeve 92 into the rotating guide sleeve 4, and then through the middle port 102, side port 12, annular groove 53, and connecting cavity 52 into the fixed frame 62. This allows the pressurized air to enter the elastic sleeve frame 63 through the connecting port 64, causing the elastic sleeve frame 63 to inflate and expand rapidly. During expansion, the impact pushes the grinding beads into contact, causing them to accelerate. Simultaneously, the control solenoid valve 94 is intermittently activated, causing the elastic sleeve 63 to rapidly expand, deform, and contract, completing the intermittent ejection of the grinding assembly. The grinding beads change their direction and speed within the grinding cylinder 1, resulting in more thorough grinding and refining of the material. Furthermore, during the rotational grinding process, the rotating guide sleeve 4 drives the cleaning component 11 to rotate rapidly. The cleaning component 11 rotates along the interior of the filter discharge section 3, performing friction cleaning on the filter holes 33, thus completing simultaneous unclogging. When grinding is complete... After processing, as the material and grinding beads in the sand mill cylinder 1 are discharged, the air supply component 9 is kept ventilated, allowing pressurized air to be input into the rotating guide sleeve 4. The reversing component 10 is activated, the electric push rod 103 is activated, and the inner tube 101 is moved, so that the middle port 102 is offset from the side port 12. After the movement, it is connected to the blowing port 13 and blown out through the blowing port 13. As the power component 8 drives the rotating guide sleeve 4 to rotate, the blowing port 13 rotates and blows along the inside of the sand mill cylinder 1, completing the internal blowing and cleaning, and completing the drying and cleaning process.
