Description

Technical Field

[0001] The invention relates to the technical field of rubber product processing, in particular to a rubber product calendering device. Background Art

[0002] Rubber product calendering is a common rubber processing technology, mainly used to produce rubber products with specific shapes and sizes. The calendering process is based on the plasticity of rubber at high temperatures. The molten rubber passes through one or more pairs of rollers. The shape and spacing of the rollers determine the shape and thickness of the final product. It is often used to manufacture flat rubber, rubber sheets, rubber belts and other products. For example, in the construction field, it is used to produce window rubber; in the electronics industry, it is used to manufacture rubber substrates for liquid crystal displays;

[0003] In combination with the above content, it should be explained that: the first set of rollers in the calendering equipment directly contacts the high-temperature and irregularly shaped rubber raw materials. Affected by the high temperature, material shape and contact pressure, it is easy to cause the first set of rollers of the calendering equipment to have abnormal problems such as serious roller wear, material adhesion or concave-convex defects on the surface of the pressed products compared with the subsequent rollers. When the traditional calendering equipment encounters abnormal conditions of the first set of rollers, it needs to be stopped for replacement and maintenance, which seriously affects the continuous production efficiency of the overall rubber products.

[0015] A working method of a rubber product calendering device comprises the following steps

[0016] S1: When the raw materials of rubber products are transported to the roller body close to the main roller group, the telescopic cylinder arm drives the roller body and the lower roller group a1 to approach each other through the connecting clamp and the adapter kit until the gap between the two reaches the specified requirement. The servo motor drives the roller body to rotate at a constant speed through the adapter kit to calender the raw materials of rubber products close to it;

[0017] S2: The stretching cylinder drives the arc-shaped blade to move until the front end of the blade is attached to the surface of the roller body, and the adjusting cylinder drives the movable suction cover to slide down and approach the blade;

[0018] As the roller body rotates, the shovel blade removes the rough materials attached to its surface, and the arc micromotor drives the spiral conveyor frame to rotate, so that the heavy rough materials scooped up by the shovel blade are crushed by the rotation of the spiral conveyor frame body. At the same time, as the spiral conveyor frame rotates, the crushed rough materials trapped in the guide groove are pushed to the discharge port area;

[0019] The port area of ​​the movable suction hood is subjected to the operation of the external suction device to generate a negative pressure suction area, and the small and light wool on the shovel blade is affected by the pressure of the negative pressure suction area and is sucked into the movable suction hood;

[0020] The top of the coating scraper is connected to the external anti-sticking material box through pipe fittings and external valves. The anti-sticking material box transports anti-sticking liquid material to the coating scraper through a pump group. The anti-sticking liquid material overflows between the coating scrapers and continuously applies the anti-sticking liquid material to the surface of the roller body to reduce the adhesion between the raw materials of the rubber products and the roller body.

[0021] S3: Temporarily slow down the running speed of the calendering production line equipment. The rotary cylinder of the main roller group drives the telescopic cylinder arm to tilt and deflect clockwise in the direction of S5 through the mechanical shaft sleeve and the anti-slip kit. At the same time, the telescopic cylinder arm drives the roller body to extend and expand, so as to pre-press some rubber products on the calendering production line equipment.

[0022] The movable cover frame temporarily moves away from the main roll group and the lower roll group a1 through the coordinated operation of the side shaft rod and the external driving structure, while the auxiliary roll group and the lower roll group a2 alternately approach the preset position, and the movable cover frame is reset to approach the upper roll body of the auxiliary roll group and the lower roll group a2;

[0023] S4: The rotary cylinder drives the telescopic cylinder arm to rotate counterclockwise, causing the roll body on it to move along the s1 direction, and the telescopic cylinder arm drives the roll body to move along the s2 direction to achieve the ultimate contraction of the main roll group. After the auxiliary roll group and the slag cleaning mechanism are in place, the rotary cylinder rotates clockwise along the s3 direction until the roll body on it is located above the heat cover mechanism, the telescopic cylinder arm extends along the s4 direction, and the rotary cylinder drives the telescopic cylinder arm to rotate in the opposite direction along the s3 axis by a certain angle, causing the roll body on it to fit into the heat cover mechanism;

[0024] S5: The semi-arc cover and the upper side cover are connected with the outer shell and the lower side cover of the electric heater. The industrial camera installed on the top frame of the calendering production line equipment samples the data of the roll body and compares the sampled data with the comparison samples inside the general control center. Based on this, the abnormal area on the surface of the roll body of this group is obtained, and the numerical control personnel adjust the operation of the roll repair mechanism according to the comparison results;

[0025] The traction cylinder frame drives the sliding frame to move axially along the inner side of the semi-arc cover, and the upper and lower pressing cylinders of the sliding frame drive the plating pen to slide down and contact the roller body, so as to perform brush plating treatment on the defective areas on the surface of the roller body in a small range;

[0026] S6: The cylinder is pushed to drive the abutment turn plate to rotate until the inner wall of the abutment turn plate contacts the surface of the roller body. The brush plating area is sealed in combination with the electric heater and the side lower cover. The electric heater generates heat during operation to perform targeted rapid heat treatment on the brush plating area.

[0027] The beneficial effects of the present invention are:

[0028] 1. The present invention uses the alternating coordinated operation of the main roller group and the auxiliary roller group to facilitate the linkage replacement of the vulnerable first group of roller bodies, which is convenient for rapid repair and treatment, while avoiding the shutdown of the calendering production line equipment, realizing the continuous processing of rubber product calendering, effectively improving production efficiency, reducing the generation of defective rubber products and the cost of damage, maintenance and scrapping of vulnerable roller groups;

[0029] 2. The present invention uses a slag cleaning mechanism in conjunction with the roller body to facilitate continuous slag removal on the surface of the roller body, and to grade the removed raw materials. The heavier raw materials are crushed and sucked out by the spiral conveyor, and the light raw materials are sucked out by the movable suction hood. At the same time, the surface of the roller body after cleaning is continuously and evenly scraped with an anti-adhesion coating;

[0030] 3. The present invention performs surface sampling and comparison on the replaced roll body, so that the numerical control personnel can operate the roll repair mechanism and the heat cover mechanism to carry out targeted quick repair treatment on the abnormal roll body, thereby realizing the automatic repair of the vulnerable roll body, and completing the repair treatment of the damaged roll body safely and efficiently while ensuring the normal operation of the calendering production line.

8. A method for operating a rubber product calendering device, used in the rubber product calendering device according to any one of claims 1 to 7, characterized in that: The following steps are included S1: When the raw material of the rubber product is transported to the roller body (6) close to the main roller group (1), the telescopic cylinder arm (105) drives the roller body (6) and the lower roller group a1 to approach each other through the connecting clamp (106) and the adapter kit (602) until the gap between the two reaches the specified requirement, and the servo motor (601) drives the roller body (6) to rotate at a constant speed through the adapter kit (602) to calender the raw material of the rubber product close to it; S2: The stretching cylinder (307) drives the arc-shaped abutment sheet (305) to move until the front end of the shovel sheet is attached to the surface of the roller body (6), and the adjusting cylinder drives the movable suction cover (304) to slide down and approach the shovel sheet; As the roller body (6) rotates, the scraper blade scrapes away the raw materials attached to the surface thereof, and the micromotor drives the spiral conveyor frame (310) to rotate, so that the raw materials that are scooped up by the scraper blade and are relatively heavy are crushed by the rotation of the spiral conveyor frame (310). At the same time, as the spiral conveyor frame (310) rotates, the crushed raw materials that are retained in the guide groove (308) are pushed to the discharge port (311) area; The port area of ​​the movable suction hood (304) generates a negative pressure suction area due to the operation of the external suction device, and the small and light wool material on the shovel blade is affected by the pressure of the negative pressure suction area and is sucked into the movable suction hood (304); The top of the coating scraper (306) is connected to an external anti-sticking material box through a pipe fitting and an external valve (302). The anti-sticking material box transports anti-sticking liquid material to the coating scraper (306) through a pump group. The anti-sticking liquid material overflows between the coating scraper (306) and is continuously applied to the surface of the roller body (6), thereby reducing the adhesion between the raw materials of the rubber product and the roller body (6). S3: The running speed of the calendering production line equipment is temporarily slowed down, and the rotary cylinder (102) of the main roller group (1) drives the telescopic cylinder arm (105) to tilt and deflect clockwise in the direction of S5 through the mechanical shaft sleeve (103) and the anti-slip kit (104). At the same time, the telescopic cylinder arm (105) drives the roller body (6) to extend and unfold, so as to pre-press some rubber products on the calendering production line equipment; The movable cover frame (301) temporarily moves away from the main roller group (1) and the lower roller group a1 through the coordinated operation of the side shaft rod (303) and the external driving structure, while the auxiliary roller group (2) and the lower roller group a2 alternately approach the preset position, and the movable cover frame (301) is reset to be close to the upper roller body (6) of the auxiliary roller group (2) and the lower roller group a2; S4: the rotary cylinder (102) drives the telescopic cylinder arm (105) to rotate counterclockwise, causing the roller body (6) thereon to move in the direction of s1, and the telescopic cylinder arm (105) drives the roller body (6) thereon to move in the direction of s2, thereby achieving the ultimate contraction of the main roller group (1). After the auxiliary roller group (2) and the slag cleaning mechanism (3) are in place, the rotary cylinder (102) rotates clockwise in the direction of s3 until the roller body (6) thereon is located above the heat shield mechanism (5), the telescopic cylinder arm (105) extends in the direction of s4, and the rotary cylinder (102) drives the telescopic cylinder arm (105) to rotate in the opposite direction along the axial direction of s3 by a certain angle, causing the roller body (6) thereon to fit and snap into the heat shield mechanism (5); S5: The semi-arc cover (401) and the upper side cover (407) are connected to the outer shell of the electric heater (503) and the lower side cover (504), and the industrial camera installed on the top frame of the rolling production line equipment samples the data of the roller body (6), and compares the sampled data with the comparison sample inside the main control center, thereby obtaining the abnormal area on the surface of the group of roller bodies (6), and the numerical control personnel adjust the operation of the roller repair mechanism (4) according to the comparison result; The traction cylinder frame (405) drives the sliding frame (404) to move axially along the interior of the semi-arc cover (401), and the upper and lower pressure cylinders of the sliding frame (404) drive the plating pen (406) to slide down and contact the roller body (6), so as to perform a small-scale brush plating treatment on the defective area on the surface of the roller body (6); S6: The cylinder is pushed to drive the abutment rotating plate (502) to rotate until the inner wall of the abutment rotating plate (502) contacts the surface of the roller body (6), and the brush plating area is sealed in combination with the electric heater (503) and the side lower cover (504). The electric heater (503) generates heat during operation, and the brush plating area is subjected to targeted rapid heat treatment.
