Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor belt manufacturing, and in particular relates to an automatic extrusion mechanism for an integral belt core of a whole-core conveyor belt. Background Art

[0002] The fabric core conveyor belt is made of a high-strength fabric core woven from polyester / cotton as the skeleton layer, impregnated with PVC paste and extruded with PVC / PVG surface adhesive covering layer. The upper and lower covering layers of the PVC type are both PVC covering adhesive, and the upper and lower covering layers of the PVG type are both rubber and plastic covering adhesive. The fabric core conveyor belt has excellent flame retardant and antistatic properties; it has the advantages of small elongation, light belt body, no belt delamination, impact resistance, tear resistance, and good belt body troughing performance; the PVG type is coated with rubber as the main material, which further improves the troughing performance, surface anti-slip performance, low temperature resistance and wear resistance of the conveyor belt on the basis of the PVC type. Therefore, it not only improves the conveying inclination angle, but also greatly extends the service life of the conveyor belt; the joint is convenient, easy to install and maintain. It can be used for conveying materials in coal mines and other occasions that require flame retardancy and antistatic, and can also be used for material transportation in metallurgy, chemical industry, power, mining and other industries. The PVC type is suitable for conveying materials with a conveying angle of no more than 16°, and the PVG type is suitable for conveying materials with a conveying angle of no more than 22°.

[0003] The manufacturing process of the fabric whole core conveyor belt is as follows: guide the whole belt core away → brush and suck the whole belt core → dry the whole belt core → immerse the whole belt core in the paste pool → plasticize the whole belt core → granulate the covering rubber powder and extrude it on the whole belt core → cool → inspect the appearance → curl the finished product → pack and store. In the step of "immersing the whole belt core in the paste pool", the whole belt core needs to be immersed in the paste of the paste pool so that the paste in the paste pool can be immersed in the whole belt core. However, the whole belt core cannot meet the production requirements after only one immersion. It is necessary to squeeze the whole belt core at least once so that the paste already immersed in the whole belt core is squeezed out, and the whole belt core is immersed in the paste pool again, so as to ensure that the whole belt core is evenly and fully immersed in the paste, and then ensure the performance index requirements such as the bonding strength of the whole core conveyor belt. Therefore, an extrusion device is needed to extrude the whole belt core in the paste pool. Utility Model Content

[0038] The lifting mechanism includes two groups of lifting components that are symmetrical on both sides. The two groups of lifting components are respectively arranged at the left and right ends of the sliding seat 7. Each group of lifting components includes a lifting rod 17, a track plate 19, a telescopic rod 21, a telescopic cylinder 20, and a telescopic spring 23.

[0039] A square lifting hole is provided at the left and right ends of the sliding seat 7, and a square vertical lifting rod 17 is slidably inserted in each lifting hole. A squeezing roller 18 is rotatably provided between the lower ends of the two lifting rods 17, and the squeezing roller 18 is horizontally provided along the left and right directions, and the left and right ends of the squeezing roller 18 are rotatably connected to the lower ends of the two lifting rods 17.

[0040] A track plate 19 is provided on each side of the two lifting rods 17 away from each other. The two track plates 19 are located on the left and right sides of the two lifting rods 17 respectively, and the two track plates 19 are fixedly provided on the end surfaces of the two fixing plates 5 close to each other.

[0041] Each lifting rod 17 is provided with a telescopic through hole that passes through from left to right. A telescopic cylinder 20 is fixedly provided on the side of the telescopic through hole away from the track plate 19 on the same side. The telescopic cylinder 20 is a circular cylindrical structure with one end open. The opening of the telescopic cylinder 20 corresponds to the telescopic through hole. The axis of the telescopic cylinder 20 coincides with the axis of the telescopic through hole. The inner diameter of the telescopic cylinder 20 is larger than the inner diameter of the telescopic through hole. The same telescopic rod 21 is inserted into the telescopic cylinder 20 and the telescopic through hole. The outer cylindrical surface of the telescopic rod 21 maintains sliding contact with the inner wall of the telescopic through hole. An action ring 22 is fixedly provided on the outer cylindrical surface of the telescopic rod 21. The action ring 22 is located inside the telescopic cylinder 20. A telescopic spring 23 is sleeved on the outer side of the telescopic rod 21. The telescopic spring 23 is located inside the telescopic cylinder 20. The two ends of the telescopic spring 23 are fixedly connected to the action ring 22 and the inner bottom surface of the telescopic cylinder 20 respectively.

[0042] A track groove 24 is provided on one end surface of the track plate 19 near the telescopic rod 21 on the same side, and one end of the telescopic rod 21 near the track plate 19 is inserted into the track groove 24. The track groove 24 is a parallelogram structure formed by sequentially splicing an upper horizontal section 25, a lower horizontal section 26, a front inclined section 28, and a rear inclined section 27. The upper horizontal section 25 and the lower horizontal section 26 are both horizontally arranged along the front-to-back direction, the front inclined section 28 is parallel to the rear inclined section 27, and the upper ends of the front inclined section 28 and the rear inclined section 27 are both inclined forward. The inner depth of the lower horizontal section 26 gradually decreases from back to front, and the inner depth of the upper horizontal section 25 gradually decreases from front to back. The inner depth of the front inclined section 28 is the same as the depth of the front end of the lower horizontal section 26 and is higher than the height of the front end of the upper horizontal section 25. The inner depth of the rear inclined section 27 is the same as the depth of the rear end of the upper horizontal section 25 and is higher than the height of the rear end of the lower horizontal section 26. When the end of the telescopic rod 21 is inserted into the upper horizontal section 25, the squeezing roller 18 is out of contact with the integral belt core 4; when the end of the telescopic rod 21 is inserted into the lower horizontal section 26, the squeezing roller 18 maintains sliding contact with the integral belt core 4.

[0043] A scraper 29 is arranged at the rear side of the squeezing roller 18, and the left and right ends of the scraper 29 are fixedly connected to the lifting rods 17 on both sides. The scraper 29 is a horizontally arranged "︿"-shaped structure, and the sharp corner in the middle of the scraper 29 extends horizontally backward. When the squeezing roller 18 contacts the integral belt core 4, the scraper 29 contacts the integral belt core 4; when the squeezing roller 18 is out of contact with the integral belt core 4, the scraper 29 is out of contact with the integral belt core 4.

[0044] The working principle of the utility model is:

[0045] When the pulling device pulls the integral belt core 4 to move backward, the integral belt core 4 always keeps sliding backward on the extrusion platform 2. The driving motor 9 is started, and when the driving motor 9 rotates, the crank 10 is driven to rotate, and the crank 10 drives the connecting rod 11 to swing, so that the sliding seat 7 slides back and forth on the guide rod 6. The sliding seat 7 drives the extrusion rollers 18 to slide back and forth through the lifting rods 17 on both sides.

[0046] When the ends of the telescopic rods 21 on both sides are located at the rear end of the lower horizontal section 26, the squeezing roller 18 and the scraper strip 29 are in contact with the integral belt core 4, and the sliding seat 7 is located at the rearmost position.

[0047] When the sliding seat 7 is driven by the driving motor 9, the crank 10 and the connecting rod 11, the end of the telescopic rod 21 cannot enter the interior of the rear inclined section 27 and can only slide forward inside the lower horizontal section 26 because the depth of the lower end of the rear inclined section 27 is smaller than the depth of the rear end of the lower horizontal section 26; since the depth of the lower horizontal section 26 gradually decreases from back to front, the length of the end of the telescopic rod 21 inserted into the track groove 24 gradually decreases, and the telescopic spring 23 is gradually compressed. As the end of the telescopic rod 21 slides inside the lower horizontal section 26, the lifting rod 17 maintains a constant height, and the squeezing roller 18 squeezes the integral belt core 4, so that the paste that has been immersed in the integral belt core 4 is squeezed out, and the squeezed paste is scraped by the scraper 29 and slides forward on the integral belt core 4. Since the scraper 29 is a "︿"-shaped structure, the squeezed paste is concentrated in the middle of the scraper 29 and slides forward.

[0048] When the end of the telescopic rod 21 reaches the front end of the lower horizontal section 26, the sliding seat 7 continues to slide forward, so the end of the telescopic rod 21 enters the interior of the front inclined section 28 and gradually slides toward the upper end of the front inclined section 28, thereby driving the lifting rod 17 to slide upward inside the lifting through hole of the sliding seat 7. The lifting rods 17 on both sides drive the squeezing roller 18 and the scraper 29 to rise, thereby breaking contact with the integral belt core 4. At this time, the integral belt core 4 continues to move backward and reintegrates the paste that has been concentrated on the integral belt core 4 into the paste inside the paste pool 1.

[0049] When the sliding seat 7 slides to the front end, it starts to slide backward. At this time, the end of the telescopic rod 21 extends into the front end of the upper horizontal section 25. The resilience of the telescopic spring 23 makes the end of the telescopic rod 21 closely contact the inner bottom surface of the front end of the upper horizontal section 25. Since the depth of the upper end of the front inclined section 28 is smaller than the depth of the front end of the upper horizontal section 25, the end of the telescopic rod 21 can no longer return to the interior of the front inclined section 28 and can only slide backward inside the upper horizontal section 25. Since the depth inside the upper horizontal section 25 gradually decreases from front to back, the length of the end of the telescopic rod 21 inserted into the track groove 24 gradually decreases, and the telescopic spring 23 is gradually compressed. As the end of the telescopic rod 21 slides inside the upper horizontal section 25, the lifting rod 17 maintains a constant height, and the squeezing roller 18 and the scraper 29 are always out of contact with the integral belt core 4.

[0050] When the end of the telescopic rod 21 reaches the rear end of the upper horizontal section 25, the sliding seat 7 continues to slide backward, so the end of the telescopic rod 21 enters the interior of the rear inclined section 27 and gradually slides toward the lower end of the rear inclined section 27, thereby driving the lifting rod 17 to slide downward inside the lifting hole of the sliding seat 7, and the lifting rods 17 on both sides drive the squeezing roller 18 and the scraping strip 29 to descend, thereby gradually contacting the integral belt core 4. The area section of the integral belt core 4 that has been squeezed and scraped just moves to this point, and the squeezing roller 18 begins to squeeze and scrape the next area section of the integral belt core 4, and repeats continuously, thereby squeezing and scraping each section of the integral belt core 4.

[0051] By rotating the screw rod 15 through the handle 16, the slider 14 can be driven to slide inside the slide rail 13, so that the distance between the end of the connecting rod 11 and the output shaft of the drive motor 9 is adjusted, thereby adjusting the sliding distance of the sliding seat 7, thereby ensuring that when the sliding seat 7 slides to the rearmost end, the end of the telescopic rod 21 is exactly located at the rear end of the lower horizontal section 26; when the sliding seat 7 slides to the frontmost end, the end of the telescopic rod 21 is exactly located at the front end of the upper horizontal section 25.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
