Description

Technical Field

[0001] This utility model belongs to the technical field of high tensile rubber processing equipment, specifically a high-efficiency molding device for high tensile rubber. Background Technology

[0002] Conveyor belts, also known as transport belts, are rubber and fiber, metal composite products, or plastic and fabric composite products used in belt conveyors to carry and transport materials. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemicals, and steel for short-distance and small-volume transport. Conveyor belts with a cotton or steel wire core are calendered. In the calendering process, heated rubber compound is passed through the gap between two horizontally arranged, relatively rotating rollers to form the desired semi-finished rubber sheet.

[0003] In the existing rubber conveyor belt calendering process, the raw rubber material of the high-tensile conveyor belt will come into direct contact with the calendering mechanism, resulting in rubber material residue on the calendering mechanism. This is usually cleaned manually, which requires stopping the machine and thus affecting work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency molding device for high-tensile rubber to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-efficiency molding device for high-tensile rubber is provided, comprising a frame, a heating mechanism fixedly connected to the left side of the top of the frame, a guide cylinder movably connected inside the heating mechanism, a calendering mechanism fixedly connected to the right side of the top of the frame, a screw threadedly connected inside the calendering mechanism, and scraping mechanisms fixedly connected to the inner side of the calendering mechanism and the lower part of the screw. The scraping mechanism includes a fixed cylinder fixedly connected to the inner side of the calendering mechanism and the lower part of the screw, a limit plate movably connected inside the fixed cylinder, a spring fixedly connected between the fixed cylinder and the limit plate, a scraper fixedly connected to the right side of the limit plate, and a guide post fixedly connected to the top of the scraper.

[0006] Optionally, the frame includes a placement plate, the lower part of which is fixedly connected to a support column, a fixing column is fixedly connected between the left and right support columns, and a connecting column is fixedly connected between the fixing columns.

[0007] Optionally, the heating mechanism includes a column fixedly connected to the top left side of the placement plate, with fixed plates fixedly connected above and below the column, and heat lamps fixedly connected to the lower part of the upper fixed plate and the top of the lower fixed plate. The column has a lifting groove inside, and bolts are placed inside the column.

[0008] Optionally, the calendering mechanism includes a fixed frame, the fixed frame having a first screw hole inside, a hydraulic telescopic rod fixedly connected inside the fixed frame, a lifting block movably connected to the lower part of the hydraulic telescopic rod, a driven pressure cylinder movably connected between the lifting blocks, a motor fixedly connected to the front side of the fixed frame, and an active pressure cylinder fixedly connected to the output end of the motor.

[0009] Optionally, the screw includes a column threadedly connected inside the fixing frame, with a limit block fixedly connected to the lower part of the column, a connecting block movably connected to the outer side of the limit block, and a screwing block fixedly connected to the top of the column.

[0010] Optionally, the guide cylinder includes a lifting column movably connected inside the column, the lifting column having a second screw hole inside, a fixed shaft fixedly connected to both sides of the lifting column, and a cylinder movably connected to the outside of the fixed shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by setting up a scraping mechanism, can scrape off the residual raw material on the surface of the active and driven pressure cylinders, eliminating the need for manual shutdown for cleaning and improving work efficiency. During calendering, the active pressure cylinder rotates clockwise, and the driven pressure cylinder rotates counterclockwise. The rubber material scraped off by the clockwise rotation of the active pressure cylinder is located below the lower scraper and falls directly onto the placement plate under gravity. The rubber material scraped off by the counterclockwise rotation of the driven pressure cylinder is located above the upper scraper. As the scraped rubber material accumulates, the later scraped rubber material continuously compresses the earlier scraped rubber material. This continuous compression causes the earlier scraped rubber material to move towards the guide column, bringing it into contact with the guide column. Under the compression, the earlier scraped rubber material moves along the guide column to the front and rear sides of the scraper, allowing it to fall onto the placement plate from the front and rear sides of the scraper. This prevents the scraped rubber material from falling directly onto the calendered rubber material, thus preventing bulging after calendering. Attached Figure Description

[0024] Reference Figures 1 to 5 The present invention will now be described. A high-efficiency molding device for high-tensile rubber includes a frame 1. A heating mechanism 2 is fixedly connected to the left side of the top of the frame 1. A guide cylinder 6 is movably connected inside the heating mechanism 2. A calendering mechanism 3 is fixedly connected to the right side of the top of the frame 1. A screw 4 is threadedly connected inside the calendering mechanism 3. A scraping mechanism 5 is fixedly connected to the inner side of the calendering mechanism 3 and the lower part of the screw 4. The scraping mechanism 5 includes a fixed cylinder 501 fixedly connected to the inner side of the calendering mechanism 3 and the lower part of the screw 4. A limit plate 503 is movably connected inside the fixed cylinder 501. A spring 502 is fixedly connected between the fixed cylinder 501 and the limit plate 503. A scraper 505 is fixedly connected to the right side of the limiting plate 503. The limiting plate 503 and the scraper 505 can move inside the fixed cylinder 501. A guide post 504 is fixedly connected to the top of the scraper 505. The guide post 504 is used to guide the scraped rubber material. In use, the spring 502 is in a compressed state. Under the elastic force of the spring 502, the scraper 505 can press against the surfaces of the driven pressure cylinder 305 and the driving pressure cylinder 306. The motor 307 is started, which drives the driving pressure cylinder 306 to rotate, thereby calendering and conveying the rubber material between the driving pressure cylinder 306 and the driven pressure cylinder 305. As 305 rotates, the residual rubber material on the surfaces of the active and driven pressure cylinders 306 can be scraped off by the scraper 505, eliminating the need for manual cleaning and improving work efficiency. During calendering, the active pressure cylinder 306 rotates clockwise, and the driven pressure cylinder 305 rotates counterclockwise. The rubber material scraped off by the clockwise rotation of the active pressure cylinder 306 is located below the lower scraper 505 and falls directly onto the placement plate 101 under gravity. The rubber material scraped off by the counterclockwise rotation of the driven pressure cylinder 305 is located above the upper scraper 505, and as the scraped rubber material accumulates, it is scraped off later. The rubber material continuously squeezes the scraped rubber material, causing it to move towards the guide post 504. This continuous movement brings the scraped rubber material into contact with the guide post 504. Under the squeezing action, the scraped rubber material moves along the guide post 504 towards the front and rear sides of the scraper 505. This continuous movement causes the scraped rubber material to fall onto the placement plate 101 from the front and rear sides of the scraper 505, preventing it from falling directly onto the calendered rubber material and thus preventing bulging after the rubber material is calendered.

[0025] Furthermore, the frame 1 includes a placement plate 101, with a support column 104 fixedly connected to the lower part of the placement plate 101, a fixing column 103 fixedly connected between the left and right support columns 104, and a connecting column 102 fixedly connected between the fixing columns 103. The frame 1 is used to place and fix the components of the device.

[0026] Furthermore, the heating mechanism 2 includes a column 201 fixedly connected to the top left side of the placement plate 101. Fixing plates 205 are fixedly connected to the upper and lower parts of the column 201. Heat lamps 202 are fixedly connected to the lower part of the upper fixing plate 205 and the top of the lower fixing plate 205. The heat lamps 202 are used to heat the rubber raw material, so that the rubber raw material can be easily calendered by the calendering mechanism 3. The column 201 is provided with a lifting groove 204 inside, which is used for lifting the column 601. Bolts 203 are placed inside the column 201, which are used to fix the guide cylinder 6.

[0027] Furthermore, the calendering mechanism 3 includes a fixed frame 301, with a first screw hole 303 inside the fixed frame 301. A hydraulic telescopic rod 302 is fixedly connected inside the fixed frame 301. A lifting block 304 is movably connected to the lower part of the hydraulic telescopic rod 302. The lifting block 304 can rise and fall inside the fixed frame 301. A driven pressure cylinder 305 is movably connected between the lifting blocks 304. The driven pressure cylinder 305 can rotate between the lifting blocks 304. A motor 307 is fixedly connected to the front side of the fixed frame 301. An active pressure cylinder 306 is fixedly connected to the output end of the motor 307. The hydraulic telescopic rod 302 is activated. 02. The lifting block 304 is raised and lowered, thereby adjusting the height of the driven pressure cylinder 305 and the distance between the driven pressure cylinder 305 and the driving pressure cylinder 306, so as to calender rubber conveyor belts of different thicknesses; the heated rubber raw material is placed between the driving pressure cylinder 306 and the driven pressure cylinder 305, and the motor 307 is started to drive the driving pressure cylinder 306 to rotate, so that the rubber raw material can continuously enter between the driving pressure cylinder 306 and the driven pressure cylinder 305, and the rubber raw material is shaped under the squeezing action of the driving pressure cylinder 306 and the driven pressure cylinder 305.

[0028] Furthermore, the screw 4 includes a column 403 threadedly connected inside the fixed frame 301. The outer side of the column 403 is threaded, and the first screw hole 303 is adapted to the thread on the outer side of the column 403. A limiting block 402 is fixedly connected to the lower part of the column 403. The limiting block 402 can rotate inside the connecting block 401. The connecting block 401 is movably connected to the outer side of the limiting block 402. A screwing block 404 is fixedly connected to the top of the column 403. The connecting block 401 is fixedly connected to the scraping mechanism 5 above. By screwing the screwing block 404, the column 403 is rotated. The forward and reverse rotation of the column 403 allows it to rise and fall inside the fixed frame 301, thereby driving the scraping mechanism 5 above to rise and fall, so as to align with the driven pressure cylinder 305.

[0029] Furthermore, the guide cylinder 6 includes a lifting column 601 movably connected inside the column 201. The lifting column 601 has a second screw hole 604 inside, which is adapted to the thread on the outside of the bolt 203. Fixed shafts 602 are fixedly connected to both sides of the lifting column 601. A cylinder 603 is movably connected to the outside of the fixed shaft 602. The cylinder 603 can rotate outside the fixed shaft 602. By loosening the bolt 203, the lifting column 601 can rise and fall in the lifting groove 204, thereby adjusting the distance between the upper and lower guide cylinders 6 to guide rubber materials of different thicknesses.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
