Description

Technical Field

[0001] The invention discloses a two-station synthetic rubber briquetting machine, belonging to the field of post-treatment of synthetic rubber. Background Art

[0002] Patent document CN206501338U discloses a synthetic rubber briquetting and forming machine, which can extrude bulk rubber materials into dense square rubber blocks by the pressure of a hydraulic cylinder, and push the rubber blocks to a packaging production line by a horizontal cylinder. This type of briquetting machine belongs to a three-station working mode. The stroke of the horizontal cylinder is large and the reciprocating movement distance is long, so its production efficiency is not high, and the maximum production capacity is 160 pieces per hour; since a movement gap needs to be left between the horizontally moving cover plate and the lower cavity, and this gap will continuously increase with the sliding wear of the horizontal cover plate, resulting in the rubber material being extruded from the gap during briquetting and becoming the flash of the rubber block, which will affect the subsequent packaging process of the rubber block. Summary of the Invention

[0003] In order to solve the problems of low working efficiency and flash on rubber blocks in the existing three-station synthetic rubber briquetting machine, the present invention proposes a two-station synthetic rubber briquetting machine, which includes a machine body 1, a horizontal cylinder bracket 2, a horizontal oil cylinder 3, an upper cover plate assembly 4, a briquetting cavity 5, an extrusion plate 6, a cavity oil cylinder 7, and a vertical oil cylinder 8. The machine body 1 is of a door frame structure. The machine body 1 includes vertical wallboards 12 on both left and right sides. The lower end of the vertical wallboard 12 is provided with a lower end plate 11, and the upper end of the vertical wallboard 12 is provided with an upper end plate 13. A feed inlet is provided in the middle of the upper end plate 13. A cavity guide rail 16 is vertically provided on the inner side of the vertical wallboard 12, and a horizontal guide rail 14 in the front-back direction is also provided on the upper part of the inner side of the vertical wallboard 12. The lower end plate 11 is connected to the cylinder body of the vertical oil cylinder 8, and the upper end of the cylinder rod of the vertical oil cylinder 8 is connected to the extrusion plate 6. The extrusion plate 6 is located inside the briquetting cavity 5. The briquetting cavity 5 includes a cavity 51 with upper and lower openings. Sliders 52 are provided on the outer sides of the four outer corners of the cavity 51. The sliders 52 can slide up and down along the cavity guide rail 16. The left and right lower end faces of the cavity 51 are hinged to the upper ends of the levers of the cavity oil cylinders 7 on both left and right sides. The cylinder body of the cavity oil cylinder 7 is connected to the lower end plate 11. The cavity oil cylinder 7 drives the briquetting cavity 5 to move up and down. The vertical oil cylinder 8 drives the extrusion plate 6 to slide up and down along the inner walls around the cavity 51. Below the upper end plate 13 is provided with an upper cover plate assembly 4. The upper cover plate assembly 4 is located above the briquetting cavity 5. The upper cover plate assembly 4 includes a blanking cylinder 42. A connecting seat 41 is provided at the rear end of the blanking cylinder 42, and an upper cover plate 43 is provided at the front end of the blanking cylinder 42. Roller wheels 44 are provided on the upper left and right sides of the upper cover plate 43. The front part of the upper cover plate 43 is hinged to the front ends of swing arms 45 on both left and right sides. The outer sides of the rear ends of the swing arms 45 are hinged to pulleys 46. A push rod 47 is provided between the inner sides of the rear ends of the swing arms 45 on both left and right sides. The connecting seat 41 is hinged to the cylinder rod of the horizontal oil cylinder 3. The cylinder body of the horizontal oil cylinder 3 is connected to the horizontal cylinder bracket 2. The horizontal cylinder bracket 2 is fixed on the machine body 1. The horizontal oil cylinder 3 drives the upper cover plate assembly 4 to move back and forth. The roller wheels 44 roll on the upper surface of the horizontal guide rail 14, and the pulleys 46 roll on the upper end surface of the cavity 51.

[0004] On the upper part of the inner side of the vertical wallboard 12, a guiding and limiting block 15 is also provided. An inverted conical hole with a downward opening is provided inside the guiding and limiting block 15. Cones 53 are provided on the left and right outer sides of the cavity 51. When the briquetting cavity 5 rises to the high position, the cones 53 are inserted into the inverted conical holes inside the guiding and limiting block 15.

[0005] The position of the guiding and limiting block 15 can be adjusted up and down.

[0006] The working principle of the present invention is:

[0007] A. Blanking stage: The horizontal oil cylinder 3 extends to align the blanking cylinder 42 with the briquetting cavity 5. The cavity oil cylinder 7 extends to raise the briquetting cavity 5 to a high position. The cone 53 is inserted into the inverted cone hole inside the guiding and limiting block 15. A very small gap is reserved between the upper end face of the cavity 51 and the lower surface of the upper cover plate 43. The vertical oil cylinder 8 drives the extrusion plate 6 to descend to a low position. The weighing system above the briquetting machine inputs a quantitative amount of rubber compound into the cavity formed by the cavity 51 and the extrusion plate 6;

[0008] B. Briquetting stage: After blanking, the horizontal oil cylinder 3 retracts to move the upper cover plate 43 backward to directly above the cavity 51. The vertical oil cylinder 8 drives the extrusion plate 6 to move upward to extrude the rubber compound in the cavity 51. Under the combined action of the upper cover plate 43, the cavity 51 and the extrusion plate 6, the loose rubber compound is extruded into a dense square rubber block A;

[0009] C. Glue discharging stage: The vertical oil cylinder 8 drives the extrusion plate 6 to move downward a small distance. The cavity oil cylinder 7 retracts to lower the briquetting cavity 5 to a low position, making the lower surface of the square rubber block A flush with the upper end face of the cavity 51. At this time, the push rod 47 has descended to near the lower part of the rear end of the square rubber block A under the action of gravity. Then the horizontal oil cylinder 3 extends to drive the push rod 47 to push the square rubber block A forward away from the cavity 51, and at the same time aligns the blanking cylinder 42 with the briquetting cavity 5 to enter the next working cycle.

[0010] The beneficial effects of the present invention are:

[0011] A. By using the liftable briquetting cavity 5, the square rubber block A formed by extrusion can be quickly in a state where it can be pushed out, shortening the preparation action time and improving the working efficiency;

[0012] B. After the square rubber block A is in a state where it can be pushed out, the horizontal oil cylinder 3 directly drives the push rod 47 to push the square rubber block A forward away from the cavity 51, shortening the stroke of the horizontal oil cylinder 3 and the number of reciprocating motions, thus greatly reducing the action time of the horizontal oil cylinder 3 and improving the production capacity;

[0013] C. By using the guiding and limiting block 15 with adjustable up and down positions, the gap between the upper end face of the cavity 51 and the lower surface of the upper cover plate 43 can be adjusted at any time, so that there will be no flash during the briquetting process, reducing the loss of rubber compound. At the same time, it also reduces the downtime for maintenance caused by replacing various worn parts in the upper cover plate assembly 4, improving the equipment efficiency and reliability;

[0014] D. By reducing the action time and optimizing the action steps, the production capacity of the two-station synthetic rubber briquetting machine can reach more than 200 pieces per hour. Description of the Drawings
