Description

Technical Field

[0001] The invention relates to the technical field of processing and grinding, in particular to a raw material grinder for packaging adhesive. Background Art

[0002] Packaging adhesives are used to connect homogeneous or heterogeneous surfaces. They are suitable for connecting different materials, different thicknesses, ultra-thin specifications and complex components, and are widely used in various industries. During the adhesive production process, some raw materials usually need to be ground to obtain finer particles, thereby achieving the effect of mutual fusion between the raw materials.

[0003] In the prior art, raw materials for packaging adhesives are typically ground coarsely using a roller grinder, followed by secondary grinding using an airflow grinder or a finer roller grinder to achieve the required fine particle precision. However, this grinding method requires multiple steps, which affects production efficiency. Furthermore, the prior art also employs a method of implementing a multi-stage grinding structure within a single grinding device, filtering the powder ground by each grinding structure through a filter assembly to achieve the multi-stage grinding effect. While this device reduces the transfer process, it is bulky and, even with an anti-clogging structure, particles can still accumulate and clog as they move between the various grinding structures through the filter assembly, resulting in low production efficiency. Summary of the Invention

[0011] Preferably, the filter assembly includes a filter cartridge and a fan disposed in the filter cartridge, and filter screens or filter plates are provided on the side and bottom surfaces of the filter cartridge.

[0012] Preferably, an annular oblique block is provided on the annular air duct, and the guide plate is arranged on the annular oblique block. The height of the annular oblique block close to the grinding disk is consistent with the bottom of the shell, and the cross-sectional area of ​​the annular oblique block gradually increases from one side close to the grinding disk to the other side.

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

[0014] Preferably, a feed baffle is provided in the feed pipe for controlling the connection between the feed pipe and the inside of the shell, and the discharge pipe is perpendicular to the axis of the shell at one end away from the shell.

[0017] In addition, by setting up an air blowing component, the air flow enters the shell through the annular air duct, and then the air flow rises in a spiral shape, carrying the particles with smaller particle size after grinding to the discharge pipe, and is filtered through the filter component so that the raw material particles that meet the requirements and are ground to the required position are transported out of the shell. Since the air flow moves upward in a spiral, the upward force of the air flow near the shell is stronger, and the upward force of the air flow at the center of the shell is smaller, and the raw materials with inconsistent particle diameters move to the central filter component with the air flow. If they fail to pass through the filter component under the initial impact of the air flow, they will fall back to the bottom of the shell due to the reduction of the air flow force and under the action of their own gravity, and then be ground through the grinding component.

[0018] Furthermore, by adjusting the orientation of the guide plate, the direction of the airflow entering the housing is aligned with the direction of rotation of the grinding disc, that is, opposite to the direction of the particles moving upward along the shovel plate. This allows the airflow to blow directly against the raw materials lifted by the shovel plate, thereby improving the efficiency of the airflow. Therefore, the structure of the present invention eliminates the need for multi-stage grinding and filtering structures, thereby reducing the volume and avoiding the blockage of raw materials between the transfer and multi-stage grinding structures, thereby ensuring grinding accuracy and efficiency. Therefore, the present invention solves the problem of the prior art lacking a small and highly efficient raw material grinder for packaging adhesives. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] DETAILED DESCRIPTION

[0029] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0030] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See also Figures 1 to 7, shown is a raw material grinder for packaging adhesive in an embodiment of the present invention, comprising a shell 10, with a feed pipe 11 and a discharge pipe 12 provided at the top of the shell 10; a grinding assembly 20, comprising a grinding disc 21 arranged at the bottom of the shell 10, first grinding rollers 22 and shovel plates 23 arranged alternately on the outside of the grinding disc 21, a first driving component 24 and a second driving component 25 arranged in the grinding disc 21, the first driving component 24 being used to drive the grinding disc 21 to rotate, and the second driving component 25 being used to drive the first grinding roller 22 to rotate; an air blowing assembly 30, comprising an annular air duct 31 arranged on the outside of the bottom of the shell 10, a guide plate 32 arranged in the annular air duct 31 and an air blowing component 33 connected to the annular air duct 31, a plurality of guide plates 32 being equidistantly distributed circumferentially around the axis of the annular air duct 31, and a flow direction of the gas entering the shell 10 along the guide plates 32 being consistent with the rotation direction of the grinding disc 21; a filter assembly 40, arranged at the top of the shell 10 and connected to the discharge pipe 12.

[0033] It can be understood that the abrasive raw material enters the shell 10 and is located at the grinding assembly 20 through the feed pipe 11 on the shell 10, and moves to the outside of the grinding disk 21 through the grinding disk 21. The first grinding roller 22 on the outside of the grinding disk 21 is ground under the action of the second driving component 25, and the grinding disk 21 drives the first grinding roller 22 and the shovel plate 23 to rotate under the action of the first driving component 24, so that the shovel plate 23 scoops up the raw material at the bottom of the shell 10, and the raw material moves up and down along the shovel plate 23 and is lifted up, thereby preventing the raw material from accumulating or adhering to the bottom of the shell 10 during grinding.

[0034] In addition, by setting up the blowing component 30, the air flow enters the shell 10 through the annular air duct 31, and then the air flow rises in a spiral shape, carrying the particles with smaller particle size after grinding to the discharge pipe 12, and is filtered through the filter component 40 so that the raw material particles that meet the requirements and are ground to the required position are transported out of the shell 10. Since the air flow moves upward in a spiral, the upward force of the air flow near the shell 10 in the shell 10 is stronger, and the upward force of the air flow at the center of the shell 10 is smaller, and then the raw materials with inconsistent particle diameters move with the air flow to the central filter component 40. If they fail to pass through the filter component 40 under the initial impact force of the air flow, they will fall back to the bottom of the shell 10 due to the reduction of the air flow force and under the action of their own gravity, and then be ground through the grinding component 20.

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

[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. 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. During specific implementation, the adhesive is ground or the raw material that 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, the raw material particles blown up by the blowing assembly 30 will also be subjected to the grinding action of the second grinding roller 26 and the grinding plate during their upward spiral movement along the housing 10, further reducing the proportion of unground raw material particles that move upward, thereby improving the grinding effect and efficiency.

[0037] In addition, a transmission assembly 50 is provided above the grinding assembly 20, and the transmission assembly 50 includes an annular block 51 connected to the shell 10, an annular groove 52 arranged at the bottom of the annular block 51 and an annular sliding plate 53 arranged in the annular groove 52. A first annular guide groove 54 is provided on the inner wall of the annular groove 52 close to the side of the shell 10. The first annular guide groove 54 is distributed in a wave shape, and one end of the rotating 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 the side. In practice, the grinding disc 21 drives the second grinding roller 26 to rotate via the connecting member 28, causing the second grinding roller 26 to drive the annular sliding plate 53 to slide within the annular chute, thereby causing the first guide rod 262 to move along the first annular guide groove 54. Because the first annular guide groove 54 has an undulating, wave-like structure, the second grinding roller 26 moves up and down as it rotates. The ball grinding and up and down movement of the second grinding roller 26 disrupt the state and force of the raw material particles during grinding, further improving the grinding effect. Furthermore, the vibration effect of the up and down movement of the second grinding roller 26 can also reduce the probability of raw material particles adhering to the second grinding roller 26 or the annular grinding plate 27, thereby preventing a decrease in grinding efficiency.

[0038] Specifically, the second drive component 25 includes a ring gear 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 ring gear 251. The inner portion of the grinding disc 21 is hollow, allowing the ring gear 251 to be positioned within the inner portion of the grinding disc 21. In practice, the first drive component 24 drives the grinding disc 21 to rotate, which in turn drives the first grinding roller 22 to rotate about its axis. Furthermore, the gear 252 cooperates with the ring gear 251, allowing the first grinding roller 22 to rotate simultaneously with its own rotation, thereby achieving a rotational grinding effect. This is achieved using a single power source, reducing the cost of the grinder.

[0039] In addition, a toggle assembly 60 is embedded on the outside of the grinding disc 21. The toggle assembly 60 includes a toggle block 61, a driving rod 62 connected to the toggle block 61, and a second annular guide groove 63 arranged in the grinding disc 21. The second annular guide groove 63 is distributed in a wave shape. One end of the driving rod 62 is connected to the toggle block 61, and the other end is provided with a second guide rod 64 adapted to the second guide groove. The toggle block 61 is rotatably connected to the grinding disc 21 away from the side of the driving rod 62. During specific implementation, the grinding disc 21 rotates, driving the toggle assembly 60 to rotate, thereby causing the second guide rod 64 to move along the second guide groove. Since the second guide is a wavy structure that undulates inside and outside, the driving rod 62 will continuously approach or move away from the center of the grinding disc 21, thereby causing the toggle block 61 to continuously push the material outward and then automatically retract, thereby realizing the pushing and stacking effect of the raw material, so that the raw material will be accumulated and ground at the center of the first grinding roller 22, thereby improving the grinding efficiency and effect of the raw material. In addition, the toggle block 61 is wing-shaped and by adjusting the direction of rotation and the structural distribution of the toggle block 61, it is difficult for the raw material to enter between the toggle block 61 and the grinding disc 21 when the toggle block 61 is pushing the material, thereby avoiding the situation where the raw material is stuck between the toggle block 61 and the grinding disc 21, avoiding affecting the grinding efficiency of the raw material, and avoiding the situation where the raw material is stuck and the toggle assembly 60 is damaged.

[0040] Specifically, the filter assembly 40 includes a filter cartridge 41 and a fan 42 disposed within the filter cartridge 41. Filter screens or filter plates are provided on the sides and bottom of the filter cartridge 41. By disposing the fan 42 within the filter cartridge 41, the rising airflow drives the fan 42 to rotate, further accelerating the raw material particles entering the filter cartridge 41. This improves discharge efficiency and prevents the accumulation of raw material particles in the filter cartridge 41 due to insufficient upward force from the annular airflow and the center.

[0041] In addition, an annular duct 31 is provided with an annular bevel block 34, and a guide plate 32 is disposed on the annular bevel block 34. The height of the annular bevel block 34 on the side closest to the grinding disc 21 is consistent with the bottom of the housing 10, and the cross-sectional area of ​​the annular bevel block 34 gradually increases from the side closest to the grinding disc 21 to the other side. In a specific implementation, the provision of the annular bevel block 34 allows the raw material particles to accumulate at the bottom of the housing 10 during grinding and not enter the annular duct 31, thereby preventing the particles from not being ground within the annular 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 is connected to the grinding disc 21. In a specific implementation, the provision of the support frame 13 allows the housing 10 to be suspended and fixed, thereby facilitating the fixing and installation of the housing 10. In addition, the suspended housing 10 provides sufficient space for the motor of the first distinguishing component, so that the motor and the transmission rod cooperate to drive the grinding disc 21 to rotate.

[0043] In addition, the top of the grinding disc 21 is conical, and the blowing assembly 30 intermittently blows air into the housing 10 according to a preset rule. In a 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 downward along the conical grinding disc 21 to the first grinding roller 22. Furthermore, 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. The air blowing is interrupted after a certain period of time, so that the raw material particles that do not meet the requirements fall quickly to the bottom of the housing 10. The wave-like blowing effect realizes a pulse or vibration effect, so that the pulsed or vibrating gas impact force acts on the interior of the housing 10, the grinding assembly 20, and the filter assembly 40, thereby further preventing the adhesion or clogging of the raw material particles.

[0044] Specifically, a feed baffle is provided in the feed pipe 11 to control the connection between the feed pipe 11 and the inside of the shell 10, and the discharge pipe 12 is perpendicular to the axis of the shell 10 at one end away from the shell 10. In a specific implementation, after the feeding of the raw material particles is completed, the particles are blocked by the feed baffle to prevent them from flowing out of the feed pipe 11. And by coordinating with the intermittent blowing of the blowing component 30, the feeding can be carried out through the feed pipe 11 when the blowing component 30 stops blowing, thereby ensuring the continuity of the raw material grinding and improving the grinding efficiency of the raw material. In addition, the discharge pipe 12 is bent at one end to prevent the raw material particles from falling back from the discharge pipe 12 to the filter component 40 in the shell 10 during intermittent blowing.

[0045] In summary, the present invention allows the abrasive raw material to enter the shell 10 and be located at the grinding assembly 20 through the feed pipe 11 on the shell 10, and move to the outside of the grinding disk 21 through the grinding disk 21, and is ground by the first grinding roller 22 on the outside of the grinding disk 21 under the action of the second driving component 25, and the grinding disk 21 drives the first grinding roller 22 and the shovel plate 23 to rotate under the action of the first driving component 24, so that the shovel plate 23 scoops up the raw material at the bottom of the shell 10, and the raw material moves up and down along the shovel plate 23 and is lifted up, thereby preventing the raw material from accumulating or adhering to the bottom of the shell 10 during grinding.

[0046] In addition, by setting up the blowing component 30, the air flow enters the shell 10 through the annular air duct 31, and then the air flow rises in a spiral shape, carrying the particles with smaller particle size after grinding to the discharge pipe 12, and is filtered through the filter component 40 so that the raw material particles that meet the requirements and are ground to the required position are transported out of the shell 10. Since the air flow moves upward in a spiral, the upward force of the air flow near the shell 10 in the shell 10 is stronger, and the upward force of the air flow at the center of the shell 10 is smaller, and then the raw materials with inconsistent particle diameters move with the air flow to the central filter component 40. If they fail to pass through the filter component 40 under the initial impact force of the air flow, they will fall back to the bottom of the shell 10 due to the reduction of the air flow force and under the action of their own gravity, and then be ground through the grinding component 20.

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