Description

Technical Field

[0001] The invention relates to the field of mechanical design, positioning and manufacturing, and in particular to a high temperature resistant original sheet stringing and positioning device. Background Art

[0002] In the early stage, the quality of short roller coating directly affects the production of glass substrates. Due to the thickness deviation of the high-temperature resistant original sheet after extrusion and compression, the hardness difference range on the detection circle after the material is processed and formed becomes larger. The high-temperature resistant original sheet contacts the glass plate and pulls the glass downward. The uneven daily wear of the high-temperature resistant original sheet leads to eccentric wear during the use of the high-temperature resistant original sheet.

[0003] During the short roller coating operation, due to the inconsistent thickness of the high-temperature resistant original sheets themselves, there is a certain deviation in thickness after multiple sheets are stacked together. Due to the limitation that the coating tooling has no limit, the stacked original sheets are strung onto the shaft to be coated and lowered onto the tooling as a whole. A transition device in the middle acts on the stacked original sheets, and the intermediate transition tooling is pushed by the cylinder to act on the original sheets. The original sheets are deformed and compressed by force. The transition tooling is affected by the uneven thickness of the stacked original sheets, and is prone to a certain tilt. In addition, there is inconsistency in the measured thickness of the original sheets after compression. It is necessary to compress the original sheets and rotate them as a whole for secondary extrusion to improve the uniformity of the thickness of the coated original sheets. The thickness of the stacked original sheets is greater than the actual length of the coating shaft. During the coating process, the stacked original sheets need to be extruded multiple times to be completely inserted into the shaft. Therefore, a high-temperature resistant original sheet stringing and positioning device is urgently needed to solve the above defects. Summary of the invention

[0010] Furthermore, a positioning seat is fixedly mounted on one end of the guide rod away from the oil cylinder connecting piece, and a positioning top is provided at the bottom of the positioning seat, and a center hole is provided at the bottom of the positioning top.

[0011] Furthermore, the center hole is opened at the top of the roller core, and the size of the center hole is adapted to the positioning center. At the same time, the positioning center is inserted into the center hole, and the cross-sections of the center hole and the positioning center are both conical, and the depth of the center hole is equal to the height of the positioning center.

[0012] Furthermore, a limiting hole is opened on the upper side of the positioning seat, and a limiting plate is arranged on one side of the limiting hole.

[0027] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0028] Specific implementation method 1: Please refer to Figure 1-6The present invention provides a technical solution: a high-temperature resistant original sheet stringing and positioning device, comprising an upper working table 1, a guide column 2 is fixedly installed at the bottom of the upper working table 1, and a transition tooling 4 is movably installed on the guide column 2, and a hydraulic cylinder 31 is screwed and fixed on the bottom surface of the upper working table 1, and the piston rod of the hydraulic cylinder 31 is connected to a guide rod 8 through a cylinder connector 3 and a bolt, and a plurality of groups of stacked original sheets 9 are evenly arranged on the surface of the guide rod 8 away from the cylinder connector 3, and a limiting plate 10 is arranged at the bottom of the stacked original sheets 9, and a roller core 5 is installed at the bottom of the guide rod 8, and the roller core 5 is arranged through the lower working table 7, a positioning reference block 6 is fixedly arranged at the bottom of the roller core 5, and two groups of positioning reference blocks 6 are linearly arranged at the bottom of the roller core 5, and the upper working table 1 and the lower working table 7 are arranged in parallel.

[0029] Working principle: The existing short roll coating equipment stand is optimized, and a guide column device is added between the upper working table 1 and the lower working table 7. The guide column device consists of four sets of parallel guide columns 2, which are perpendicular to the upper and lower working tables. The upper and lower sides of the transition tooling 4 are parallel to the working table. The transition tooling 4 is designed on the four sets of guide columns 2 and moves up and down with the hydraulic cylinder 31 to ensure that the high-temperature resistant original sheet can continue to maintain verticality with the table after being deformed by force, and is not affected by the uneven thickness of the high-temperature resistant material itself. The two bearing blocks at the bottom of the coated roller core 5 are designed as positioning reference blocks 6, which are on the cylinder connector 3. Add guide holes, and keep concentricity with the two bearing block axes at the bottom of the coated roller core 5. At this time, a guide rod 8 is made to match with the hole of the cylinder connector 3 with clearance. The surface design of the guide rod 8 requires smoothness and high hardness treatment to ensure that the guide rod 8 can move freely up and down along the cylinder connector 3. The bottom of the guide rod 8 is positioned and installed with the roller core 5 through the positioning top 83 and the center hole 831. When the hydraulic cylinder 31 moves downward to drive the intermediate transition tooling 4 to move to the appropriate position, the fastening bolts on the cylinder connector 3 are opened, and the guide rod 8 and the roller core 5 are formed into a whole after the positioning top 83 of the guide rod 8 axis coincides with the center hole 831 on the roller core 5. This can solve the problem that the axial length of the coated section of the roller core 5 is less than the thickness of the high-temperature resistant original sheet to be coated, and the high-temperature resistant original sheet to be coated can be coated at one time. The original sheet is strung onto the guide rod 8, and the limit plate 10 is inserted to prevent the original sheet from falling. As the hydraulic cylinder 31 drives the transition tooling 4 to move downward to a suitable position, the limit plate 10 is removed, and the high-temperature resistant original sheet is affected by gravity and automatically strung onto the roller core 5 to be coated, thereby solving the problem of repeated operations after the high-temperature resistant materials are divided into several groups in the early stage of coating, reducing the difficulty of operation and improving the efficiency of coating. Since the coating process involves the flatness control of the upper and lower tooling and the one-time extrusion and molding of multiple original sheets after stacking, in order to stabilize the flatness control of the upper and lower tooling, ensure the uniformity of the thickness of the high-temperature resistant original sheet during the extrusion process, and solve the problem of the coating axis length being less than the thickness of the high-temperature resistant original sheet to be coated during the operation of the operator, multiple sheet-threading operations are avoided, and a simple and convenient operation method is provided.
