Description

Technical Field

[0001] This utility model relates to the field of rubber lining technology, specifically to a rubber lining molding device. Background Technology

[0002] In industrial production, rubber lining technology is widely used in the protection of the inner walls of various pipelines. By attaching the rubber lining to the inner wall of the pipe with adhesive, the corrosion resistance, wear resistance, and sealing performance of the pipeline can be effectively enhanced, extending the service life of the pipeline and reducing maintenance costs. After the rubber lining is attached to the inner wall of the pipe, it is usually necessary to extrude and mold the rubber lining and the pipe to make the bond stronger. The traditional extrusion molding method is mainly done manually, with workers holding rollers to roll and press the rubber lining. However, manual operation makes it difficult to ensure that the pressure applied by the rollers to the rubber lining is uniform and consistent, and for long or large diameter pipelines, manual operation is inefficient.

[0003] For example, the patent document CN220390327U proposes a pipe rubber lining extrusion molding device. This device uses pressure rollers inside the pipe to extrude and mold the rubber lining and the pipe, which improves the efficiency of extrusion molding and ensures uniform pressure. However, the length and height of the pressure rollers are fixed. Therefore, this device can only be used for pipes of limited length and single diameter, and its application range is relatively small.

[0004] To address these issues, we have designed a rubber lining molding device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-6 This utility model provides a rubber lining molding device, the base 1 of which adopts a split structure, consisting of a left base plate 101, a middle base plate 102 and a right base plate 103 connected by a plug-in structure. The right side of the left base plate 101 and the right side of the middle base plate 102 are provided with first slots 104, and the left side of the middle base plate 102 and the left side of the right base plate 103 are provided with first inserts 105 that match the first slots 104. After the inserts are inserted into the slots, they are fixed with bolts to form a stable support platform. A pair of first support rollers 3 are installed on the left base plate 101 and the right base plate 103 respectively, and a pair of second support rollers 5 are installed on the middle base plate 102. The first support rollers 3 and the second support rollers 5 cooperate to support the tube with rubber lining on the left and right. A motor 4 is installed on the bracket of the first support roller 3. The output shaft of the motor 4 is connected to the shaft of the first support roller 3. The function of the motor 4 is to drive the support roller 3 to rotate, thereby driving the tube placed on the support roller to rotate.

[0025] The pressure roller 2 adopts a three-section splicing structure, consisting of a left cylinder 201, a middle cylinder 202, and a right cylinder 203. The right end of the left cylinder 201 and the right end of the middle cylinder 202 are both provided with a second slot 204. The left end of the middle cylinder 202 and the left end of the right cylinder 203 are both provided with a second insert 205 that matches the second slot 204. After the insert is inserted into the slot, it is fixed with bolts, realizing the quick assembly and disassembly of the pressure roller 2. The bolts that fix the second slot 204 and the second insert 205 are hexagon socket head cap screws. The hole on the outside of the second slot 204 for connecting the bolt is a countersunk hole. The countersunk hole can hide the head of the hexagon socket head cap screw, avoiding the head of the bolt from squeezing or scratching the rubber lining. The two ends of the pressure roller 2 are mounted between two bearing seats 11 through a shaft rotation. The bearing seats 11 are connected to the support block 8 through a buckle 10. The bottom of the support block 8 is connected to the support plate 6 through a hydraulic cylinder 9. The hydraulic cylinder 9 can drive the support block 8 to rise and fall, thereby adjusting the pressure of the pressure roller 2 on the rubber lining.

[0026] Example 2: Based on Example 1, the positioning structure of the support block 8 and the bearing seat 11 is further optimized. The positioning block 12 is installed on the top of the support block 8, and the positioning hole 13 is opened at the corresponding position on the bottom of the bearing seat 11. When the bearing seat 11 is connected to the support block 8, the positioning block 12 is inserted into the positioning hole 13, thereby ensuring the accuracy of the installation position of the bearing seat 11 and improving the installation accuracy and stability of the pressure roller 2.

[0027] Example 3: Based on Example 1, the connection between the support plate 6 and the support block 8 is further optimized. Four guide posts 7 are installed on the top of the support plate 6, and four guide holes for the guide posts 7 to be inserted are opened at the bottom of the support block 8. Through the cooperation of the guide posts 7 and the guide holes, the output rod of the hydraulic cylinder 9 can be prevented from deflecting when working. At the same time, an axial through hole is opened in the middle of the guide post 7, and a radial hole communicating with the axial through hole is opened on the side near the bottom. These holes allow the guide hole to communicate with the outside, so that the air pressure in the guide hole is always consistent with the outside.

[0028] Example 4: In practical applications, the splicing method of the base 1 and the pressure roller 2 can be flexibly adjusted according to the different specifications and molding requirements of the pipe and the rubber lining. For example, for the rubber lining in a short pipe, only the left cylinder 201 and the right cylinder 203 can be spliced ​​to form a shorter pressure roller 2. At the same time, the left bottom 101 and the right bottom plate 103 can be spliced ​​to form a shorter base 1, so that the bearing seats 11 at both ends of the short pressure roller can match the positions of the two support blocks 8 on the short base. Similarly, for the rubber lining in a long pipe, the number of the middle bottom plate 102 and the middle cylinder 202 can be increased to splice a longer base 1 and pressure roller 2. The left and right widths of the middle bottom plate 102 are equal to the length of the middle cylinder 202, so that the bearing seats 11 at both ends of the long pressure roller can match the positions of the two support blocks 8 on the long base. At the same time, the hydraulic cylinder 9 can adjust the height of the support blocks 8 as needed, thereby changing the pressure of the pressure roller 2 on the rubber lining to meet the molding requirements of rubber linings with different thicknesses and hardnesses.

[0029] Operating Procedure: Before using the device, adjust the number of base plates 102 and cylinders 202 of the pressure rollers 2 according to the length of the tube. After attaching the rubber lining to the inner wall of the tube with glue, place the tube on the support roller of the base 1. Pass the pressure roller 2 through the middle of the tube, and then fix the bearing seats 11 at both ends of the pressure roller 2 to the support block 8 through the buckles 10. Start the hydraulic cylinder 9 to control the pressure roller 2 to press on the rubber lining. Then start the motor 4 to drive the tube to rotate, so that the pressure roller 2 can extrude and form the rubber lining on the inner wall of the tube. After the rubber lining is formed, turn off the motor 4 and start the hydraulic cylinder 9 to control the pressure roller 2 to reset. Then open the buckles 10 and remove the pressure roller 2 from the tube. The tube on the support roller can then be removed.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
