Description

Technical Field

[0001] The utility model belongs to the technical field of rollers, and more specifically, particularly relates to a roller glue injection molding device. Background Art

[0002] The roller is a cylindrical part, mainly used in transmission and conveying systems. The roller is usually made of a stainless steel roller body with an outer rubber coating. The outer rubber coating can effectively protect the metal roller from wear and prevent the conveyor belt from slipping, so that the roller and the belt can run synchronously, ensuring the belt's efficient and high-volume operation. At present, the outer rubber coating process of the roller requires workers to evenly apply cold adhesive glue on the surface of the roller and the rubber plate, and then adhere the semi-vulcanized CN layer rubber plate to the outer side of the metal roller by physical bonding to cover and wrap it. However, the traditional rubber coating process will form a seal on the outer side of the roller. The cold rubber coating of the roller is under long-term friction and pressure, which easily leads to the phenomenon of debonding at the sealing part of the rubber coating, which in turn causes the outer rubber coating to fall off the surface of the metal roller, causing the conveyor belt to slip and deviate.

[0023] When the utility model performs the glue injection work on the roller surface, firstly, the through holes at the center of the two groups of support plates 8 are respectively inserted into the roller shafts on the left and right sides of the roller body 5, and then the two groups of support plates 8 are respectively inserted into the two groups of annular grooves on the inner side of the lower mold cylinder 6, so that the support plates 8 support the roller body 5 to be suspended on the inner side of the lower mold cylinder 6, and then the hook of the external crane is hung on the two groups of lifting rings 4 and the four groups of hangers 9, so that the external crane hangs and transports the upper mold cylinder 1 to the upper side of the lower mold cylinder 6, and the crane drives the upper mold cylinder 1 to fall slowly, and then the worker supports the upper mold cylinder 1 to fall slowly. The upper mold cylinder 1 is held so that the sixteen groups of groove structures of the upper mold cylinder 1 are docked with the sixteen groups of groove structures at the front and rear ends of the lower mold cylinder 6. After the upper mold cylinder 1 and the lower mold cylinder 6 are docked, the flip sleeve 12 is flipped upward to flip the flip sleeve 12 into the grooves of the upper mold cylinder 1 and the lower mold cylinder 6. At this time, the nut structure of the clamping bolt 10 is located on the upper side of the groove of the upper mold cylinder 1. Then the worker uses a wrench to tighten the clamping bolt 10, and the clamping bolt 10 is screwed into the flip sleeve 12 along the threaded structure inside the flip sleeve 12 cylinder body, and the lower side of the nut structure of the clamping bolt 10 is tightened. The upper mold cylinder 1 and the lower mold cylinder 6 are connected by the fixing nut 13, and the fixing nut 13 is screwed on the outer side of the fixing bolt 10 to make the top of the fixing nut 13 fit the bottom of the flip sleeve 12 to prevent the fixing bolt 10 and the flip sleeve 12 from rotating and loosening, thereby completing the docking and closing clamping work of the upper mold cylinder 1 and the lower mold cylinder 6. After that, the worker injects the colloid into the four groups of injection ports 2, and the colloid flows into the upper mold cylinder 1 and the lower mold cylinder 6 through the injection port 2 through the through groove of the upper mold cylinder 1 until the colloid is completely filled between the upper mold cylinder 1, the drum body 5 and the lower mold cylinder 6. The gap is then opened, and the colloid is waited for to solidify and cool on the outer side of the roller body 5. After solidification, the clamping bolts 10 and the fixing nuts 13 are tightened with a wrench to separate the nut structure of the clamping bolts 10 from the pads 11, and the upper mold cylinder 1 and the lower mold cylinder 6 are loosened. Then the flip sleeve 12 is flipped outward to separate the flip sleeve 12 and the clamping bolts 10 from the groove structure of the upper mold cylinder 1 and the lower mold cylinder 6. The crane lifts the upper mold cylinder 1 and separates the upper mold cylinder 1 from the lower mold cylinder 6. Then the roller body 5 with the rubber coating is lifted out from the lower mold cylinder 6 to complete the rubber injection work on the roller surface.

[0024] In the disclosed embodiment, the upper mold cylinder 1 is a semi-cylindrical structure that passes through from left to right. The top of the semi-cylindrical structure of the upper mold cylinder 1 is provided with four groups of rectangular through grooves that pass through from top to bottom. The rectangular through grooves are arranged equidistantly, and the glue injection port 2 is docked at the rectangular through grooves of the upper mold cylinder 1, so that the molten glue is evenly injected into the upper mold cylinder 1 from the four groups of through holes, ensuring that the glue evenly wraps the surface of the roller body 5. The outer side surface of the upper mold cylinder 1 is welded with a reinforcing plate 14 and five groups of half-circle plates 3. The reinforcing plate 14 of the upper mold cylinder 1 cooperates with the half-circle plates 3 to enhance the structural strength of the upper mold cylinder 1 and prevent the metal structure of the upper mold cylinder 1 from bending and deformation under the injection pressure, ensuring that the glue on the upper half of the surface of the roller body 5 can be evenly covered. The reinforcing plates 14 at the front and rear ends of the upper mold cylinder 1 are provided with eight groups of groove structures that open up and down, and the inner side surface of the semi-cylindrical structure of the upper mold cylinder 1 is provided with two groups of annular grooves, and the upper half of the outer side surface of the support plate 8 is inserted into the groove of the upper mold cylinder 1.

[0025] In the disclosed embodiment, the lower mold cylinder 6 is a semi-cylindrical structure that passes through from left to right. The outer side surface of the lower mold cylinder 6 is welded with a reinforced plate 14 and five groups of half-circle plates 3. The reinforced plate 14 of the lower mold cylinder 6 cooperates with the half-circle plates 3 to enhance the structural strength of the upper mold cylinder 1 to prevent the metal structure of the lower mold cylinder 6 from bending and deforming under the injection pressure, ensuring that the colloid on the lower half of the surface of the drum body 5 can be evenly covered. Two groups of annular grooves are provided on the inner side surface of the semi-cylindrical structure of the lower mold cylinder 6, and the lower half of the outer side surface of the support plate 8 is inserted into the annular groove of the upper mold cylinder 1. Eight groups of groove structures with upper and lower openings are provided on the reinforced plates 14 at the front and rear ends of the lower mold cylinder 6. Convex plates are provided on the left and right sides of the bottom of each group of grooves, and a through hole that passes through from left to right is provided at the center position of each group of convex plates.

[0026] In the disclosed embodiment, the flip sleeve 12 is a cylindrical structure that passes through from top to bottom. The outer side surface of the cylindrical structure of the flip sleeve 12 is provided with two groups of symmetrically distributed bosses. The bosses of the flip sleeve 12 are rotatably connected to the through holes of the convex plate of the lower mold cylinder 6. The flip sleeve 12 can flip forward and backward in the grooves of the lower mold cylinder 6 and the upper mold cylinder 1. The inner side surface of the cylindrical structure of the flip sleeve 12 is provided with a threaded structure. The clamping bolt 10 is screwed to the threaded structure on the inner side of the cylinder of the flip sleeve 12 through the thread on the outer side surface. When the clamping bolt 10 and the flip sleeve 12 are tightened, the upper mold cylinder 1 and the lower mold cylinder 6 are closed and clamped. When the clamping bolt 10 and the flip sleeve 12 are loosened, the flip sleeve 12 can carry the clamping bolt 10 to flip out of the groove structure of the upper mold cylinder 1 and the lower mold cylinder 6, completing the integrated structure of the clamping bolt 10 and the flip sleeve 12 on the lower mold cylinder 6, preventing the clamping bolt 10 from being separated and lost.

[0027] In the disclosed embodiment, the number of the gaskets 11 is thirty-two groups, and every two groups of gaskets 11 are symmetrically distributed on the left and right sides of the groove structure of the upper mold cylinder 1. Each group of gaskets 11 is a trapezoidal structure, and the trapezoidal structure is provided with an inclined surface at an angle of 15 degrees. When the clamping bolts 10 and the flip sleeve 12 are in a tightened state, the nuts of the clamping bolts 10 are attached to the inclined surface of the trapezoidal structure of the gaskets 11, so that the flip sleeve 12 and the clamping bolts 10 are in a naturally inclined state toward the inner sides of the grooves of the lower mold cylinder 6 and the upper mold cylinder 1, preventing the flip sleeve 12 and the clamping bolts 10 from loosening and flipping outward.

[0028] In the disclosed embodiment, there are two groups of support plates 8, and each group of support plates 8 is a flange structure. A through hole is provided at the center position of the flange structure of the support plate 8, and the roller shafts at the left and right ends of the roller body 5 are respectively inserted into the center through holes of the two groups of support plates 8, so that the two groups of support plates 8 support the roller body 5 between the lower mold cylinder 6 and the upper mold cylinder 1, and an annular cylinder space is formed between the upper mold cylinder 1, the roller body 5 and the lower mold cylinder 6, so that the injected glue evenly covers the upper half of the roller body 5 and the lower plate part.

[0029] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The clamping bolts 10 and fixing nuts 13 used above are common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.
