Description

Technical Field

[0001] This invention relates to the field of processing and grinding technology, and in particular to a raw material grinding machine for packaging adhesives. Background Technology

[0002] Packaging adhesives are used to bond homogeneous or heterogeneous surfaces together. They are suitable for joining different materials, thicknesses, ultra-thin dimensions, and complex components, and have a wide range of applications. During the adhesive production process, some raw materials often need to be ground to obtain finer particles, thereby improving the fusion effect between the materials.

[0003] In existing technologies, the grinding of raw materials for packaging adhesives typically involves coarse grinding using a roller mill, followed by secondary grinding using an air jet mill or a finer roller mill to achieve the required particle size. However, this grinding method requires multiple processes, impacting production efficiency. Furthermore, existing technologies also employ multi-stage grinding structures within a single grinding unit, using filtration components to filter the powder from each grinding stage to achieve the multi-stage grinding effect. While this reduces transfer steps, the device is bulky, and even with anti-clogging mechanisms, particle accumulation and blockage can still occur as particles move between the grinding stages through the filtration components, resulting in still relatively low production efficiency. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a raw material grinding mill for packaging adhesives, which aims to solve the problem of the lack of a small-sized and highly efficient raw material grinding mill for packaging adhesives in the prior art.

[0005] According to an embodiment of the present invention, a raw material grinding mill for packaging adhesives includes a housing with an inlet pipe and an outlet pipe at the top; a grinding assembly including a grinding disc disposed at the bottom of the housing, a first grinding roller and a shovel plate disposed alternately on the outside of the grinding disc, a first driving component and a second driving component disposed within the grinding disc, the first driving component driving the grinding disc to rotate, and the second driving component driving the first grinding roller to rotate; an air blowing assembly including an annular air duct disposed on the outside of the bottom of the housing, a guide plate disposed within the annular air duct, and an air blowing component connected to the annular air duct, wherein a plurality of guide plates are equidistantly distributed circumferentially around the axis of the annular air duct, and the flow direction of gas entering the housing along the guide plates is consistent with the rotation direction of the grinding disc; and a filter assembly disposed at the top of the housing and connected to the outlet pipe.

[0006] In addition, a raw material grinding mill for packaging adhesives according to the above embodiments of the present invention may also have the following additional technical features:

[0007] Preferably, the grinding assembly further includes a second grinding roller and an annular grinding plate disposed in the middle of the housing. The annular grinding plate is disposed on the housing, and the second grinding roller is connected to the top side of the grinding disc via a connector. The second grinding roller is vertically disposed to cooperate with the annular grinding plate.

[0008] Preferably, a transmission component is provided above the grinding component. The transmission component includes an annular block connected to the housing, an annular groove disposed at the bottom of the annular block, and an annular sliding plate disposed in the annular groove. A first annular guide groove is provided on the inner wall of the annular groove near the housing. The first annular guide groove is wavy. One end of the shaft of the second grinding roller extends into the first annular guide groove and a first guide rod adapted to the first annular guide groove is provided on its side.

[0009] Preferably, the second driving component includes a gear ring disposed on the housing and a gear disposed on the drive shaft of the first grinding roller, the gear meshing with the gear ring, and the inner side of the grinding disk being hollow so that the gear ring is located inside the grinding disk.

[0010] Preferably, a toggle assembly is embedded on the outer side of the grinding disc. The toggle assembly includes a toggle block, a drive rod connected to the toggle block, and a second annular guide groove disposed in the grinding disc. The second annular guide groove is wavy. One end of the drive rod is connected to the toggle block, and the other end is provided with a second guide rod adapted to the second guide groove. The side of the toggle block away from the drive rod is rotatably connected to the grinding disc.

[0011] Preferably, the filtration assembly includes a filter cartridge and a fan disposed inside the filter cartridge, and the filter cartridge has a filter screen or filter plate on its side and bottom.

[0012] Preferably, the annular air duct is provided with an annular inclined block, the guide plate is disposed on the annular inclined block, the height of the annular inclined block near the grinding disc is consistent with the bottom of the housing, and the cross-sectional area of ​​the annular inclined block gradually increases from the side near the grinding disc to the other side.

[0013] Preferably, the bottom of the housing is provided with a support frame to suspend the housing, and the first driving component includes a motor disposed at the bottom of the housing and a transmission rod connected to the motor, the transmission rod passing through the bottom of the housing and connected to the grinding disc.

[0014] Preferably, the feed pipe is provided with a feed baffle to control the connection between the feed pipe and the inside of the housing, and the end of the discharge pipe away from the housing is perpendicular to the axis of the housing.

[0015] Preferably, the top of the grinding disc is conical, and the air blowing component intermittently blows air into the housing according to a preset rule.

[0016] In this invention, the grinding agent raw material enters the housing through the feeding pipe on the housing and is located at the grinding component position. It then moves to the outside of the grinding disc via the grinding disc. The first grinding roller on the outside of the grinding disc grinds the raw material under the action of the second driving component. The grinding disc drives the first grinding roller and the shovel plate to rotate under the action of the first driving component. This causes the shovel plate to scoop up the raw material at the bottom of the housing. The raw material moves up and down along the shovel plate and is lifted up, thereby preventing the raw material from accumulating or adhering to the bottom of the housing during grinding.

[0017] In addition, by setting up an air blowing component, the airflow enters the shell through the annular air duct, and then the airflow spirals upward, carrying the smaller particles after grinding to the discharge pipe. The particles are then filtered by the filter component, so that the raw material particles that meet the grinding requirements are transferred out of the shell. Since the airflow moves upward in a spiral, the upward force of the airflow is stronger near the shell and weaker at the center of the shell. As a result, raw materials with mismatched particle diameters move with the airflow to the central filter component. If they do not pass through the filter component under the initial impact of the airflow, they will fall back to the bottom of the shell under the action of gravity due to the reduced airflow force, and then be ground by the grinding component.

[0018] Furthermore, by adjusting the orientation of the guide plate, the airflow direction entering the housing is aligned with the rotation direction of the grinding disc, i.e., opposite to the direction in which the particles move upward along the shovel. This allows the airflow to directly blow the raw material lifted by the shovel, improving the efficiency of the airflow. Therefore, the structure of this invention eliminates the need for multi-stage grinding and filtering structures, thereby reducing the size and avoiding material blockage between transfer and multi-stage grinding structures, thus ensuring grinding accuracy and efficiency. Therefore, this invention solves the problem of the lack of a small-sized and highly efficient raw material grinder for packaging adhesives in the prior art. Attached Figure Description

Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] Please see Figures 1 to 7The image shows a raw material grinding mill for packaging adhesives according to an embodiment of the present invention, comprising a housing 10, with an inlet pipe 11 and an outlet pipe 12 at the top of the housing 10; a grinding assembly 20, comprising a grinding disc 21 disposed at the bottom of the housing 10, a first grinding roller 22 and a shovel plate 23 disposed alternately on the outside of the grinding disc 21, a first driving component 24 and a second driving component 25 disposed within the grinding disc 21, the first driving component 24 driving the grinding disc 21 to rotate, and the second driving component 25 driving the first grinding roller 22 to rotate; an air blowing assembly 30, comprising an annular air duct 31 disposed on the outside of the bottom of the housing 10, a guide plate 32 disposed within the annular air duct 31, and an air blowing component 33 connected to the annular air duct 31, wherein multiple guide plates 32 are equidistantly distributed circumferentially around the axis of the annular air duct 31, and the flow direction of gas entering the housing 10 along the guide plate 32 is consistent with the rotation direction of the grinding disc 21; and a filter assembly 40 disposed at the top of the housing 10 and connected to the outlet pipe 12.

[0033] Understandably, the abrasive material enters the housing 10 through the feed pipe 11 and is located at the grinding assembly 20. It then moves to the outside of the grinding disc 21 via the grinding disc 21. The first grinding roller 22 on the outside of the grinding disc 21 performs grinding under the action of the second drive component 25. The grinding disc 21 drives the first grinding roller 22 and the shovel plate 23 to rotate under the action of the first drive component 24. This causes the shovel plate 23 to scoop up the material at the bottom of the housing 10. The material moves up and down along the shovel plate 23 and is lifted up, thereby preventing the material from accumulating or adhering to the bottom of the housing 10 during grinding.

[0034] Furthermore, by setting the air blowing component 30, the airflow enters the housing 10 through the annular air duct 31, and the airflow rises in a spiral shape, carrying the smaller particles after grinding to the discharge pipe 12, and is filtered by the filter component 40 so that the raw material particles that meet the grinding requirements are transferred out of the housing 10. Since the airflow moves upward in a spiral, the upward force of the airflow is stronger near the housing 10 and weaker at the center of the housing 10. As a result, the raw material with a mismatched particle diameter moves with the airflow to the central filter component 40. If it does not pass through the filter component 40 under the initial airflow impact force, it will fall back to the bottom of the housing 10 under its own gravity due to the reduced airflow force, and then be ground by the grinding component 20.

[0035] Furthermore, by adjusting the orientation of the guide plate 32, the airflow direction entering the housing 10 is aligned with the rotation direction of the grinding disc 21, i.e., opposite to the direction in which the particles move upward along the shovel plate 23. This allows the airflow to directly blow the raw material lifted by the shovel plate 23, improving the efficiency of the airflow. Therefore, the structure of this invention eliminates the need for multi-stage grinding and filtering structures, thereby reducing the volume and avoiding material blockage between transfer and multi-stage grinding structures, thus ensuring grinding accuracy and efficiency. Therefore, this invention solves the problem of the lack of a small-sized and highly efficient raw material grinder for packaging adhesives in the prior art.

[0036] Specifically, the grinding assembly 20 also includes a second grinding roller 26 and an annular grinding plate 27 disposed in the middle of the housing 10. The annular grinding plate 27 is disposed on the housing 10, and the second grinding roller 26 is connected to the top side of the grinding disc 21 via a connector 28. The second grinding roller 26 is vertically arranged to cooperate with the annular grinding plate 27. In specific implementation, the raw material that has been ground or has not yet been ground is driven by the shovel plate 23, causing the raw material to move upward along the shovel plate 23 and be lifted between the second grinding roller 26 and the annular grinding plate 27 for secondary grinding, thereby further improving the grinding efficiency and grinding effect of the raw material. In addition, as the raw material particles blown up by the air blowing assembly 30 move upward along the housing 10 in a spiral motion, they will also be subjected to the grinding action of the second grinding roller 26 and the grinding plate, thereby further reducing the proportion of raw material particles that have not been ground to the required level moving upward, thereby improving the grinding effect and efficiency.

[0037] Additionally, a transmission assembly 50 is provided above the grinding assembly 20. The transmission assembly 50 includes an annular block 51 connected to the housing 10, an annular groove 52 disposed at the bottom of the annular block 51, and an annular sliding plate 53 disposed within the annular groove 52. A first annular guide groove 54 is provided on the inner wall of the annular groove 52 near the housing 10. The first annular guide groove 54 is wavy. One end of the shaft 261 of the second grinding roller 26 extends into the first annular guide groove 54, and a first guide rod 262 adapted to the first annular guide groove 54 is provided on its side. In practical implementation, the grinding disc 21 drives the second grinding roller 26 to rotate via the connector 28. This causes the second grinding roller 26 to slide the annular sliding plate 53 within the annular groove, thereby moving the first guide rod 262 along the first annular guide groove 54. Since the first annular guide groove 54 has a wave-like distribution structure with ups and downs, the second grinding roller 26 moves up and down as it rotates. Through the ball grinding and up-and-down movement of the second grinding roller 26, the state and force of the raw material particles during grinding are disrupted, further improving the grinding effect. Furthermore, the vibration effect of the up-and-down movement of the second grinding roller 26 can reduce the probability of raw material particles adhering to the second grinding roller 26 or the annular grinding plate 27, thus avoiding affecting the grinding efficiency.

[0038] Specifically, the second drive component 25 includes a gear ring 251 mounted on the housing 10 and a gear 252 mounted on the drive shaft of the first grinding roller 22. The gear 252 meshes with the gear ring 251, and the inner side of the grinding disk 21 is hollow so that the gear ring 251 is located inside the grinding disk 21. In a specific implementation, the first drive component 24 drives the grinding disk 21 to rotate, which in turn drives the first grinding roller 22 to rotate around the axis of the grinding disk 21. Furthermore, through the engagement of the gear 252 and the gear ring 251, the first grinding roller 22 rotates on its own axis while rotating, thereby achieving the rotational grinding effect of the first grinding roller 22. This is achieved using only a single power source, reducing the cost of the grinding machine.

[0039] Additionally, an actuating component 60 is embedded on the outer side of the grinding disc 21. The actuating component 60 includes a paddle 61, a drive rod 62 connected to the paddle 61, and a second annular guide groove 63 disposed in the grinding disc 21. The second annular guide groove 63 is wavy. One end of the drive rod 62 is connected to the paddle 61, and the other end is provided with a second guide rod 64 adapted to the second guide groove. The paddle 61 is rotatably connected to the grinding disc 21 on the side away from the drive rod 62. In practical implementation, the rotation of the grinding disc 21 drives the actuating component 60 to rotate, which in turn causes the second guide rod 64 to move along the second guide groove. Since the second guide has an inner and outer undulating wave-like structure, the drive rod 62 will continuously move closer to or further away from the center of the grinding disc 21, causing the actuating block 61 to continuously push the material outward and then automatically retract, thereby realizing the material pushing and accumulation function. This allows the material to accumulate and be ground at the center of the first grinding roller 22, thereby improving the grinding efficiency and effect of the material. In addition, the actuating block 61 is wing-shaped, and by adjusting the rotation direction and the structural distribution of the actuating block 61, it is difficult for the material to enter between the actuating block 61 and the grinding disc 21 when the actuating block 61 is pushing the material, thereby avoiding the situation where the material gets stuck between the actuating block 61 and the grinding disc 21, avoiding affecting the grinding efficiency of the material, and avoiding the situation where the actuating component 60 is damaged due to the material getting stuck.

[0040] Specifically, the filter assembly 40 includes a filter cartridge 41 and a fan 42 disposed inside the filter cartridge 41. Filter screens or filter plates are provided on the sides and bottom of the filter cartridge 41. By installing the fan 42 inside the filter cartridge 41, the rising airflow drives the fan 42 to rotate, thereby further accelerating the raw material particles entering the filter cartridge 41 to improve discharge efficiency and avoid the situation where the raw material particles cannot be properly processed and accumulate at the filter cartridge 41 due to insufficient upward force from the annular airflow and the center.

[0041] Additionally, an annular inclined block 34 is provided on the annular air duct 31, and a guide plate 32 is disposed on the annular inclined block 34. The height of the annular inclined block 34 near the grinding disc 21 is the same as the bottom of the housing 10, and the cross-sectional area of ​​the annular inclined block 34 gradually increases from the side near the grinding disc 21 to the other side. In specific implementation, by setting the annular inclined block 34, the raw material particles will accumulate at the bottom of the housing 10 during grinding and will not enter the annular air duct 31, thereby avoiding the situation where the particles are not ground in the annular air duct 31.

[0042] Specifically, a support frame 13 is provided at the bottom of the housing 10 to suspend the housing 10. The first driving component 24 includes a motor disposed at the bottom of the housing 10 and a transmission rod connected to the motor. The transmission rod passes through the bottom of the housing 10 and connects to the grinding disc 21. In a specific implementation, by providing the support frame 13, the housing 10 is suspended and fixed, which facilitates the fixing and installation of the housing 10. In addition, the suspended housing 10 provides sufficient space to house the motor of the first driving component, so that the motor and the transmission rod can cooperate to drive the grinding disc 21 to rotate.

[0043] Furthermore, the top of the grinding disc 21 is conical, and the air blowing component 30 intermittently blows air into the housing 10 according to a preset rule. In specific implementation, when insufficiently ground particles fall from above the housing 10 under the action of gravity, the raw material particles fall onto the grinding disc 21 and move downwards along the conical grinding disc 21 to the first grinding roller 22. In addition, in actual use, air can be blown into the housing 10 intermittently, so that the blowing force is greater each time, thereby improving the discharge efficiency. After a certain period of time, the blowing is interrupted, so that the raw material particles that do not meet the requirements fall quickly to the bottom of the housing 10. This wave-like blowing action realizes the effect of pulse or vibration, so that the pulsed or vibrating gas impact force acts on the inside of the housing 10, the grinding component 20, and the filter component 40, thereby further preventing the adhesion or blockage of raw material particles.

[0044] Specifically, the feed pipe 11 is equipped with a feed baffle to control the connection between the feed pipe 11 and the interior of the housing 10, and the end of the discharge pipe 12 away from the housing 10 is perpendicular to the axis of the housing 10. In practice, after the raw material particles are fed, the feed baffle prevents the particles from flowing out of the feed pipe 11. Furthermore, by cooperating with the intermittent blowing of the air blowing assembly 30, feed can continue through the feed pipe 11 when the air blowing assembly 30 stops blowing, thus ensuring the continuity of raw material grinding and improving the grinding efficiency. In addition, the discharge pipe 12, which is bent at one end, prevents raw material particles from falling back into the filter assembly 40 within the housing 10 during intermittent blowing.

[0045] In summary, the present invention allows the abrasive material to enter the housing 10 and be located at the grinding assembly 20 through the feed pipe 11 on the housing 10. The material then moves to the outside of the grinding disc 21 via the grinding disc 21. The first grinding roller 22 on the outside of the grinding disc 21 performs grinding under the action of the second driving component 25. The grinding disc 21 drives the first grinding roller 22 and the shovel plate 23 to rotate under the action of the first driving component 24. This causes the shovel plate 23 to scoop up the material at the bottom of the housing 10. The material moves up and down along the shovel plate 23 and is lifted up, thereby preventing the material from accumulating or adhering to the bottom of the housing 10 during grinding.

[0046] Furthermore, by setting the air blowing component 30, the airflow enters the housing 10 through the annular air duct 31, and the airflow rises in a spiral shape, carrying the smaller particles after grinding to the discharge pipe 12, and is filtered by the filter component 40 so that the raw material particles that meet the grinding requirements are transferred out of the housing 10. Since the airflow moves upward in a spiral, the upward force of the airflow is stronger near the housing 10 and weaker at the center of the housing 10. As a result, the raw material with a mismatched particle diameter moves with the airflow to the central filter component 40. If it does not pass through the filter component 40 under the initial airflow impact force, it will fall back to the bottom of the housing 10 under its own gravity due to the reduced airflow force, and then be ground by the grinding component 20.

[0047] Furthermore, by adjusting the orientation of the guide plate 32, the airflow direction entering the housing 10 is aligned with the rotation direction of the grinding disc 21, i.e., opposite to the direction in which the particles move upward along the shovel plate 23. This allows the airflow to directly blow the raw material lifted by the shovel plate 23, improving the efficiency of the airflow. Therefore, the structure of this invention eliminates the need for multi-stage grinding and filtering structures, thereby reducing the volume and avoiding material blockage between transfer and multi-stage grinding structures, thus ensuring grinding accuracy and efficiency. Therefore, this invention solves the problem of the lack of a small-sized and highly efficient raw material grinder for packaging adhesives in the prior art.
