Description

Technical Field

[0001] This utility model relates to a rubber briquetting machine, belonging to the field of synthetic rubber post-processing. Background Technology

[0002] Patent document CN206501338U discloses a pilot-scale synthetic rubber briquetting machine. After the material is received in the machine's housing, a horizontal side cylinder drives the upper door to cover the material inlet of the housing. Then, the main cylinder inside the housing rises to compact the loose rubber material into square rubber blocks. Because the upper door needs to leave a movement gap with the upper end face of the housing when it moves horizontally, and this gap will continue to increase with the sliding wear of the upper door, the rubber material is easily squeezed out from the gap during briquetting, becoming flash on the rubber block, which affects the subsequent packaging of the rubber block. Utility Model Content

[0003] To address the problem of flash forming in existing briquetting machines, this invention proposes a rubber briquetting machine. It includes a machine body with a briquetting cavity at the bottom, open at both ends. An extrusion plate is located within the cavity, connected to the cylinder rod of a vertically arranged extrusion cylinder. The cylinder body is connected to the lower end of the machine body, driving the extrusion plate to slide up and down along the inner wall of the cavity. Horizontal guide rails are arranged front and rear in the middle of the machine body. A top cover is located at the top of the machine body, with a central through-hole containing a lifting hopper. The vertical centerline of the lifting hopper coincides with the vertical centerline of the briquetting cavity. Symmetrically arranged downward-sloping wedges are positioned on the left and right sides of the lower end of the top cover. A cover plate mechanism is provided between the top cover and the briquetting cavity. The rear end of the mechanism is hinged to the cylinder rod of the horizontal hydraulic cylinder, and the cylinder body of the horizontal hydraulic cylinder is hinged to the rear end of the machine body. The cover plate mechanism includes an upper cover body. The upper left and right sides of the upper cover body are symmetrically provided with sliding plates that are inclined forward and downward and cooperate with wedges. The outer periphery of the upper cover body is provided with a support frame. The lower ends of the left and right sides of the support frame are symmetrically provided with rollers. Multiple sets of vertically arranged compression springs are provided on the left and right sides between the support frame and the upper cover body. The center of the compression spring is provided with a guide rod. The upper part of the guide rod is clearance-fitted with the upper cover body, and the lower end of the guide rod is fixed on the support frame. The upper cover body can float up and down with the compression of the compression spring. The horizontal hydraulic cylinder drives the support frame to roll along the upper end surface of the horizontal guide rail, and the gap between the upper cover body and the pressure block cavity is eliminated by the mutual wedging of the sliding plate and the wedge.

[0004] The lifting hopper includes a hanger, the lower end of which is connected to the upper end of the top cover. An inner hopper is located in the middle of the upper end of the hanger, and an outer hopper is located around the outer periphery of the inner hopper. An oil injection pipe is located at the lower part of the outer hopper. The outer hopper matches the cavity of the briquetting chamber. The outer hopper is hinged to the cylinder rod of a vertically arranged hopper lifting cylinder. The cylinder body of the hopper lifting cylinder is hinged to the machine body. The hopper lifting cylinder drives the outer hopper to lift vertically. When the outer hopper is in the lower position, the lowest end of its hopper body is connected to the upper end of the briquetting chamber or the outer hopper body extends into the briquetting chamber.

[0005] The beneficial effects of this utility model are:

[0006] A. A compression spring is installed between the support frame and the upper cover body to allow the upper cover body to float up and down. When the cover plate mechanism is driven by the horizontal hydraulic cylinder to roll along the horizontal guide rail, the slide plate moves towards the wedge. When the two wedge each other tightly, the upper cover body can move downward, thereby completely eliminating the gap between the lower end face of the upper cover body and the upper end face of the pressing block cavity, avoiding the phenomenon of flash when pressing the rubber block. In addition, the upper cover body can maintain a gap with the upper end face of the pressing block cavity during the movement and is not easy to wear. When the slide plate or wedge is severely worn and the gap cannot be eliminated, it is only necessary to replace the slide plate or wedge, which is convenient for maintenance.

[0007] B. The top cover at the upper end of the machine body can improve the overall support of the equipment, maintain the stability of the structure during long-term high-pressure pressing, avoid deformation due to stress, and improve the reliability of the equipment. Attached Figure Description

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model are described in detail below with reference to the accompanying drawings. The embodiments are exemplary and intended to explain this utility model, but should not be construed as limiting this utility model.

[0016] See Figures 1-6 A rubber briquetting machine includes a machine body 1. The lower part of the machine body 1 has a briquetting cavity 2 with openings at the top and bottom. An extrusion plate 9 is installed inside the briquetting cavity 2. The extrusion plate 9 is connected to the cylinder rod of a vertically arranged extrusion cylinder 10. The cylinder body of the extrusion cylinder 10 is connected to the lower end of the machine body 1. The extrusion cylinder 10 drives the extrusion plate 9 to slide up and down along the inner wall of the briquetting cavity 2. A horizontal guide rail 8 is arranged front and rear in the middle of the machine body 1. A top cover 6 is installed at the upper end of the machine body 1. The top cover 6 has a central section... The machine body 1 has upper and lower through holes, and a lifting hopper 5 is installed in the through holes. The vertical center line of the lifting hopper 5 coincides with the vertical center line of the pressing cavity 2. The lower end of the top cover 6 has symmetrically arranged wedges 7 that are inclined forward and downward on the left and right sides. A cover plate mechanism 3 is provided between the top cover 6 and the pressing cavity 2. The rear end of the cover plate mechanism 3 is hinged to the cylinder rod of the horizontal oil cylinder 4. The cylinder body of the horizontal oil cylinder 4 is hinged to the rear end of the machine body 1. The cover plate mechanism 3 includes an upper cover body 31. The upper cover body 31 has symmetrically arranged sliding plates 32 that are inclined forward and downward and cooperate with wedge blocks 7 on the upper left and right sides. The outer periphery of the upper cover body 31 has a support frame 33. The lower ends of the left and right sides of the support frame 33 are symmetrically arranged with rollers 36. There are eight sets of vertically arranged compression springs 34 on the left and right sides between the support frame 33 and the upper cover body 31. The center of the compression spring 34 has a guide rod 35. The upper part of the guide rod 35 is in clearance fit with the upper cover body 31. The lower end of the guide rod 35 is fixed on the support frame 33. The upper cover body 31 can float up and down with the compression of the compression springs 34. The horizontal cylinder 4 drives the support frame 33 to roll along the upper end face of the horizontal guide rail 8. The gap between the upper cover body 31 and the pressing block cavity 2 is eliminated by the mutual wedging of the sliding plates 32 and the wedge blocks 7. Preferably, the pressing block cavity 2 is a cuboid cavity. The shape of the extrusion plate 9 in the cavity matches the pressing block cavity 2. The loose rubber material is extruded into a dense rectangular rubber block in the pressing block cavity 2.

[0017] Furthermore, the lifting hopper 5 includes a hanger 51, the lower end of which is connected to the upper end of the top cover 6. An inner hopper 53 is provided in the middle of the upper end of the hanger 51, and an outer hopper 54 is provided around the outer periphery of the inner hopper 53. An oil spray pipe 55 is provided at the lower part of the outer hopper 54. The outer hopper 54 matches the cavity of the pressing block cavity 2. The outer hopper 54 is hinged to the cylinder rod of the vertically arranged hopper lifting cylinder 52. The cylinder body of the hopper lifting cylinder 52 is hinged to the machine body 1. The hopper lifting cylinder 52 drives the outer hopper 54 to lift vertically. When the outer hopper 54 is in the lower position, the lowermost end of its hopper body is connected to the upper end of the pressing block cavity 2, or the hopper body of the outer hopper 54 extends into the pressing block cavity 2. Preferably, the inner hopper 53 and the outer hopper 54 are rectangular hoppers and match the cavity of the pressing block cavity 2. Silicone oil can be sprayed into the pressing block cavity 2 by the oil spray pipe 55 according to actual needs.

[0018] See Figures 1 to 7 The working principle of this embodiment is explained as follows:

[0019] The hopper lifting cylinder 52 drives the outer hopper 54 to descend vertically, so that the lower end face of the outer hopper 54 is in contact with the upper end face of the briquetting cavity 2. The oil spray pipe 55 sprays silicone oil into the briquetting cavity 2. The weighing system above the briquetting machine puts a quantitative amount of rubber material into the cavity formed by the briquetting cavity 2 and the extrusion plate 9.

[0020] After the material is unloaded, the horizontal cylinder 4 drives the support frame 33 to roll forward along the horizontal guide rail 8 to directly above the pressure block cavity 2. At this time, the wedge block 7 and the slide plate 32 lock together, and the compression spring 34 compresses downward to completely seal the lower end face of the upper cover body 31 with the upper end face of the pressure block cavity 2. The extrusion cylinder 10 drives the extrusion plate 9 to slide upward along the inner wall of the pressure block cavity 2 to extrude the rubber material in the pressure block cavity 2. Under the combined action of the upper cover body 31, the pressure block cavity 2 and the extrusion plate 9, the loose rubber material is extruded into a dense rectangular rubber block A.

[0021] The horizontal cylinder 4 drives the cover plate mechanism 3 to roll backward back to the initial position. The extrusion cylinder 10 drives the extrusion plate 9 to continue to rise, so that the lower surface of the formed rectangular rubber block A is flush with the upper end surface of the pressing cavity 2. The horizontal cylinder 4 continues to drive the cover plate mechanism 3 to roll forward, pushing the rectangular rubber block A forward away from the pressing cavity 2. After the cover plate mechanism 3 and the extrusion plate 9 return to the initial position, the next working cycle begins.
