Description

Technical Field

[0001] The present invention belongs to the technical field of raw material processing, and particularly relates to a raw material processing device for preparing thick AB double-sided tape. Background Art

[0002] Thick AB double-sided tape is a double-sided tape composed of two different adhesives (usually acrylic adhesive or rubber-based adhesive). Its core feature is a relatively thick base material, which has excellent buffering performance, gap filling ability, and anti-vibration performance. It is mainly used in industries such as automobile manufacturing, construction and decoration, and electrical appliances. In the production process of thick AB double-sided tape, crushing and processing the raw materials of the base material is an important step.

[0003] The document with the publication number CN104959189A discloses a grading crusher, which includes a feed inlet, a discharge outlet, a crushing chamber with a screen, a crushing assembly, and a power device. The crushing assembly includes a turntable provided with hammer heads. The turntable is installed in the crushing chamber. There are crushing teeth on the turntable. The crushing chamber is provided with crushing grooves adapted to the crushing teeth. The crushing grooves are arranged along the radial end faces of the inner wall on this side. The hammer heads are arranged on the outer peripheral surface of the turntable. Further, the inlet of the crushing groove is communicated with the feed inlet, and the outlet of the crushing groove extends to the outer peripheral surface of the turntable. Still further, an internal gear ring is embedded in the inner wall of the crushing chamber. The internal gear ring is provided with crushing racks. A grinding chamber is formed between the crushing racks and the hammer heads. After the material is initially crushed by the crushing teeth, it is conveyed to the hammer heads through the crushing grooves, further refined by the hammering of the hammer heads, and then ground in the grinding chamber to grade and break the raw materials, accelerating the refinement of the raw material particles and improving work efficiency. This invention can achieve multi-stage crushing in one crushing chamber, with good crushing effect, small volume, and small occupied space. However, this crusher uses a single hammering force to break the raw materials and fails to use diversified crushing methods for processing, resulting in defects in the quality of the crushed finished products.

[0027] 1. In the present invention, by setting a graded crushing component, the main shaft rotates through multiple rotating discs and multiple crushing hammers to cooperate with the vibrating impact plate to crush the raw materials. At the same time, the connecting disc drives the vibrating impact plate to vibrate at a high frequency through the connecting rod, the rotating ring, the outer gear ring, the linkage gear, the rotating shaft, the rotating table, the extrusion block, the extrusion wheel and the sliding rod, and cooperates with the crushing hammer to crush the raw materials. By setting the rotating disc and the crushing hammer in multiple stages, the gap between the crushed raw materials can be gradually reduced from top to bottom, so that the graded processing of the raw materials can be realized and the degree of material crushing and refinement can be improved. At the same time, the main shaft drives the rotating disc to drive the crushing hammer to generate a centrifugal hammer force, which cooperates with the high-frequency vibration of the vibrating impact plate to form a composite crushing mode of impact, shearing and extrusion. The combination of hammer cutting and vibration impact can crush components of different hardness, reduce the phenomenon of over-crushing, and realize the formation of a multi-dimensional crushing effect. In addition, the vibration of the vibrating impact plate itself can avoid the adhesion and blockage of the raw materials, improve the smoothness of the unloading of the finished raw materials, and reduce the occurrence of shutdown and cleaning, thereby improving the processing efficiency.

[0028] 2. In the present invention, by setting a primary crushing component, the driving motor drives the main shaft to rotate, and the main shaft drives the rotating drum and the crushing cutter to rotate. At the same time, the main shaft drives the upper gear plate and the cutter roller to rotate in the opposite direction through the lower gear plate and the transmission gear, so that the raw materials are crushed under the interaction between the crushing cutter and the cutter roller. Through the coordinated design of the reverse rotation between the crushing cutter and the cutter roller, the frequency of shearing action on the raw materials per unit time can be significantly improved, thereby improving the crushing efficiency of the raw materials. At the same time, the eddy current field generated by the reverse rotation of the crushing cutter and the cutter roller can form a self-cleaning effect, reduce the residence time of the raw materials in the rotating drum, thereby improving the discharge efficiency of the raw materials through the discharge slot and improving the smoothness of the feeding.

[0029] 3. In the present invention, by setting a spoiler component, the rotating shaft drives the cam to rotate, and the cam drives the movable plate to move to one side, and the movable plate performs a reset movement driven by the linkage spring, so that the movable plate can drive the airbag to contract and relax periodically, and cooperate with the air intake pipe, the connecting pipe and the one-way valve to realize the one-way transmission of the airflow, so that the airflow flows through the annular box to the nozzle and is finally ejected from the nozzle. The ejected airflow disperses and blows the crushed raw materials to slow down their falling speed, so that the raw materials can fully participate in the crushing and improve the degree of refinement of the raw materials. On the other hand, the airflow can take away the moisture in the raw materials, thereby drying the raw materials and improving the quality of the finished products. BRIEF DESCRIPTION OF THE DRAWINGS

A plurality of crushing hammer blades 802 distributed in a circumferential array are hinged to the outer peripheral side of the rotating disc 801. A plurality of counterattack plate groups are arranged on the inner peripheral side of the fixed cylinder 7. The counterattack plate groups cooperate with the plurality of rotating rotating discs 801 and the crushing hammer blades 802 to perform grading and crushing on the raw materials. An annular cavity is formed inside the fixed cylinder 7. The plurality of counterattack plate groups include a plurality of vibrating counterattack plates 803. The plurality of vibrating counterattack plates 803 are distributed in a circumferential array, and there is a gap between two adjacent vibrating counterattack plates 803. One side of the vibrating counterattack plate 803 is connected with a sliding rod 804. The end of the sliding rod 804 away from the vibrating counterattack plate 803 extends into the annular cavity and is slidably connected with the annular cavity. One end of the sliding rod 804 located inside the annular cavity is connected with a pressing wheel 806. A return spring 805 is sleeved on the outer surface of the sliding rod 804. Two ends of the return spring 805 are respectively connected with one side of the pressing wheel 806 and one side of the inner wall of the annular cavity. The cross-sectional shape of the rotating disc 801 is circular, and the diameters of the plurality of rotating discs 801 gradually increase from top to bottom.

The top of the connecting disc 814 is connected with the bottom of the main rotating shaft 11.

[0047] The implementation method is specifically as follows: By setting up a grading crushing component, the main rotating shaft 11 rotates in cooperation with the vibration counterattack plate 803 through a plurality of rotating wheel disks 801 and a plurality of crushing hammer knives 802 to achieve the crushing of raw materials. At the same time, the connecting disk 814 drives the vibration counterattack plate 803 to vibrate at a high frequency through the connecting rod 813, the rotating ring 810, the external gear ring 811, the linkage gear 812, the rotating shaft 809, the rotating table 807, the extrusion block 808, the extrusion wheel 806 and the sliding rod 804, and cooperates with the crushing hammer knife 802 to achieve the crushing of raw materials. Through the multi-stage setting of the rotating wheel disk 801 and the crushing hammer knife 802, the gap for crushing raw materials can be gradually reduced from top to bottom, so as to achieve the grading treatment of raw materials, improve the degree of crushing and refinement of materials.

The other ends of the linkage springs 904 are connected to one side of the inner wall of the ring-shaped cavity. One side of the air bag 901 is communicated with an air inlet pipe 902. One end of the air inlet pipe 902 extends to the outside of the processing box 1. Two symmetrically arranged connecting pipes 903 are communicated with both sides of the air bag 901. The other ends of the plurality of connecting pipes 903 are communicated with the same annular box 908. The annular box 908 is connected to the inner wall of the ring-shaped cavity. A plurality of spray pipes 907 distributed in a circumferential array are communicated with the inner circumferential side of the annular box 908.

Check valves are arranged in both the air inlet pipe 902 and the connecting pipe 903.

[0049] The implementation method is specifically as follows: By setting the spoiler assembly 9, the rotating shaft 809 drives the cam 906 to rotate, the cam 906 drives the moving plate 905 to move to one side, and moreover, the moving plate 905 makes a reset movement driven by the linkage spring 904, so that the moving plate 905 can drive the airbag 901 to contract and expand periodically. Cooperating with the air inlet pipe 902, the connecting pipe 903 and the one-way valve can realize the one-way delivery of air flow, so that the air flow flows through the annular box 908 to the nozzle 907 and is finally ejected from the nozzle 907. The ejected air flow disperses and blows the crushed raw materials, slows down their falling speed, enables the raw materials to fully participate in crushing, and improves the refinement degree of the raw materials. On the other hand, the air flow can take away the moisture in the raw materials, thereby drying the raw materials.

[0050] The primary crushing assembly 5 includes a rotating cylinder 501, the rotating cylinder 501 is connected to the outer surface of the main rotating shaft 11, a plurality of crushing cutters 502 distributed in a circumferential array are connected to the inner peripheral side of the rotating cylinder 501, a fixed sleeve 504 is arranged in the rotating cylinder 501, a cutter roller 503 is rotatably connected to the outer surface of the fixed sleeve 504, a top gear disk 509 is connected to the bottom of the cutter roller 503, the top gear disk 509 is rotatably connected to the outer surface of the fixed sleeve 504, a transmission gear 507 is rotatably connected to one side of the fixed sleeve 504, a bottom gear disk 508 is meshed and connected to the other side of the transmission gear 507, the bottom gear disk 508 is connected to the outer surface of the main rotating shaft 11, the top of the fixed sleeve 504 is connected to the top inner wall of the processing box 1, and a plurality of discharge slots 505 distributed in a circumferential array are formed at the bottom of the rotating cylinder 501.

[0051] The implementation method is specifically as follows: By setting the primary crushing assembly 5, the drive motor 2 drives the main rotating shaft 11 to rotate, the main rotating shaft 11 drives the rotating cylinder 501 and the crushing cutters 502 to rotate. At the same time, the main rotating shaft 11 drives the top gear disk 509 and the cutter roller 503 to rotate in the reverse direction through the bottom gear disk 508 and the transmission gear 507, so that the raw materials are broken under the interaction between the crushing cutters 502 and the cutter roller 503. Through the collaborative design of the reverse rotation between the crushing cutters 502 and the cutter roller 503, the frequency of the shearing action on the raw materials per unit time can be significantly increased, thereby improving the crushing efficiency of the raw materials. At the same time, the eddy current field generated by the reverse rotation of the crushing cutters 502 and the cutter roller 503 can form a self-cleaning effect, reduce the residence time of the raw materials in the rotating cylinder 501, and thus improve the discharge efficiency of the raw materials through the discharge slots 505.

[0052] Working principle: When in use, the staff guides the raw materials into the processing box 1 through the feeding pipe 3.

Since the lower toothed disc 508 and the rotating cylinder 501 rotate in the same direction, the upper toothed disc 509 rotates in the opposite direction to the lower toothed disc 508 under the action of the transmission gear 507, so that the crushing cutter 502 and the cutting roller 503 on the rotating cylinder 501 rotate in opposite directions, so that the raw materials are crushed under the interaction between the crushing cutter 502 and the cutting roller 503.

[0053] The raw materials that have been preliminarily cut and crushed fall into the bottom of the rotating cylinder 501 through the discharge slot 505 and enter the gap between the fixed cylinder 7 and the rotating wheel disc 801 through the guide plate 6. At this time, the main rotating shaft 11 drives the multiple rotating wheel discs 801 to rotate, and the rotating wheel discs 801 drive the multiple crushing hammer knives 802 to hammer and cut the preliminarily crushed raw materials, and make the preliminarily crushed raw materials hit the vibrating impact plate 803 in the reverse direction. In this process, the main rotating shaft 11 drives the connecting plate 814 to rotate, the connecting plate 814 drives the connecting rod 813 to rotate, the connecting rod 813 drives the rotating ring 810 to rotate, and the rotating ring 810 drives The outer gear ring 811 rotates, and the outer gear ring 811 drives the linkage gear 812 to rotate, and the linkage gear 812 drives the rotating shaft 809 to rotate, and the rotating shaft 809 drives the rotating table 807 to rotate, and the rotating table 807 drives the extrusion block 808 to rotate, and the extrusion block 808 periodically drives the extrusion wheel 806 to move to one side.

[0054] During the graded crushing process of the initially crushed raw materials, the rotating ring 810 drives the linkage gear 812 to rotate, the linkage gear 812 drives the rotating shaft 809 to rotate, the rotating shaft 809 drives the cam 906 to rotate, and the cam 906 drives the movable plate 905 to move to one side, and the movable plate 905 performs a reset movement driven by the linkage spring 904, so that the movable plate 905 can drive the airbag 901 to contract and relax periodically, and cooperate with the air intake pipe 902, the connecting pipe 903 and the one-way valve to realize one-way conveyance of the airflow, so that the airflow flows through the annular box 908 to the nozzle 907 and is finally ejected from the nozzle 907 to dry the raw materials.
