Glass hot-pressing extension device

Abstract

The utility model relates to the field of glass processing, in particular to a glass hot-pressing extension device which comprises a rack, a limiting mechanism mounted at the upper end of the rack and an operation mechanism. The sliding frame is driven by the driving structure to move, so that the sliding frame drives the calendering structure to perform calendering operation on high-temperature raw materials, and when the sliding frame drives the calendering structure to operate, through sliding connection between the sliding rod and the sliding frame and limiting of the clamping block on the abutting frame, the abutting frame at the front end of the sliding rod does not move along with the sliding frame when the sliding frame moves; when a thin spring on the periphery of a sliding rod is compacted, the abutting frame can eject a clamping block into a rack through the pushing force generated by movement of a sliding frame and the elastic force of the thin spring, so that the high-temperature raw material to be machined is prevented from moving along with the high-temperature raw material to be machined, and the high-temperature raw material to be machined is prevented from being pressed by the high-temperature raw material to be machined. Therefore, the abutting frame can be popped out so as to avoid affecting continuous calendering operation.

Description

Technical Field

[0001] The utility model relates to the field of glass processing, in particular to a glass hot pressing and stretching device. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials.

[0003] After searching the patent document with the publication number CN220317621U, the patent document discloses "a glass hot pressing and stretching device, which places the high-temperature raw material between the positioning convex strips, and then the electric push rod pushes the roller frame downward, so that the calendering roller is pressed down on the positioning convex strips, and the moving frame drives the calendering roller to calender the raw material between the positioning convex strips";

[0004] When the above device is in operation, if the loaded high-temperature raw material is not completely in contact with the upper table surface, the driving structure of the above device will drive the calendering roller to move to stretch the high-temperature raw material, which will easily drag the entire mass of high-temperature raw material along with the movement, thereby resulting in the high-temperature raw material not being effectively processed. Utility Model Content

[0005] The purpose of the utility model is to provide a glass hot pressing and stretching device in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A glass hot pressing and stretching device comprises a stand, a limiting mechanism for placing materials is installed on the upper end of the stand, and an operating mechanism for processing high-temperature raw materials;

[0008] The operating mechanism includes a one-way screw, which is rotatably connected to one end of the platform, a second motor is installed at the input end of the one-way screw, a second limit rod is fixed to the other end of the platform, a sliding frame is arranged on the upper ends of the one-way screw and the second limit rod, the sliding frame is threadedly connected to the one-way screw, the sliding frame is slidably connected to the second limit rod, both ends of the sliding frame are slidably connected to sliding rods, a support frame is fixed to the front end of the sliding rod, thin springs are arranged on the periphery of the two sliding rods, the front end of the thin spring is fixed to the support frame, the rear end of the thin spring is fixed to the sliding frame, a plurality of coarse springs are fixed inside the upper end surface of the platform, and a clamping block is fixed to the upper end of the coarse spring.

[0009] Preferably: a circular plate with a diameter larger than that of the slide rod is arranged at the rear end of the slide rod.

[0010] Preferably, the uppermost end of the block when not under force is higher than the lowermost end of the support frame.

[0011] Preferably, the operating mechanism further comprises a hydraulic cylinder, which is mounted on the upper end of the sliding frame, a loading frame is fixed to the telescopic end of the hydraulic cylinder, and a pressure roller is rotatably connected in the middle of the loading frame.

[0012] Preferably: the limiting mechanism includes an extension platform, which is fixed at the upper end of the platform, a bidirectional screw is rotatably connected to the front end of the extension platform, a first motor is installed at the input end of the bidirectional screw, a first limiting rod is fixed to the rear end of the extension platform, two limiting frames are arranged above the bidirectional screw and the first limiting rod, the limiting frames are threadedly connected to the bidirectional screw, and the limiting frames are slidably connected to the first limiting rod.

[0013] Preferably, a retaining ring having a diameter larger than that of the bidirectional screw is arranged in the middle of the bidirectional screw.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] When the device performs calendering operation on high-temperature glass raw materials, through the threaded connection between the sliding frame and the one-way screw and the sliding connection between the sliding frame and the second limiting rod, the second motor drives the one-way screw to rotate to enable the sliding frame to move, thereby enabling the sliding frame to drive the calendering structure to perform calendering operation on the high-temperature raw materials. When the sliding frame drives the calendering structure to operate, through the sliding connection between the sliding rod and the sliding frame and the limitation of the support frame by the card block, the support frame at the front end of the sliding rod will not move with it while the sliding frame moves, thereby limiting the high-temperature raw materials by the support frame to avoid dragging the high-temperature raw materials to be processed when the calendering structure moves. When the fine spring on the periphery of the sliding rod is compacted, the thrust of the movement of the sliding frame plus the elastic force of the fine spring will cause the support frame to push the card block into the frame, thereby allowing the support frame to pop out to avoid affecting the continued calendering operation.

The limiting frames 24 are threadedly connected to the bidirectional screw 21, and the limiting frames 24 are slidingly connected to the first limiting rod 23. Through the threaded connection between the bidirectional screw 21 and the two limiting frames 24 and the sliding connection between the limiting frames 24 and the first limiting rod 23, when the first motor 22 drives the bidirectional screw 21 to rotate, the two limiting frames 24 can move in relative or opposite directions, so that the distance between the two limiting frames 24 can be adjusted.

[0029] The operating mechanism includes a one-way screw 3, which is rotatably connected to one end of the platform 1, a second motor 31 is installed at the input end of the one-way screw 3, a second limit rod 32 is fixed to the other end of the platform 1, a sliding frame 33 is arranged on the upper ends of the one-way screw 3 and the second limit rod 32, the sliding frame 33 is threadedly connected to the one-way screw 3, the sliding frame 33 is slidably connected to the second limit rod 32, a hydraulic cylinder 34 is installed on the upper end of the sliding frame 33, a loading frame 35 is fixed to the telescopic end of the hydraulic cylinder 34, and a pressure roller 36 is rotatably connected inside the loading frame 35, Both ends of the sliding frame 33 are slidably connected with a sliding rod 37, and a circular plate with a diameter larger than that of the sliding rod 37 is provided at the rear end of the sliding rod 37. A bracket 38 is fixed to the front end of the sliding rod 37. The upper end of the clamping block 311 is higher than the lower end of the bracket 38 when no force is applied. A thin spring 39 is provided on the periphery of the two sliding rods 37, and the front end of the thin spring 39 is fixed to the bracket 38, and the rear end of the thin spring 39 is fixed to the sliding frame 33.

Through the sliding connection between the slide bar 37 and the sliding frame 33 and the limitation of the bracket 38 by the block 311, the bracket 38 at the front end of the slide bar 37 will not move with it when the sliding frame 33 moves, so that the bracket 38 limits the high-temperature raw material to avoid dragging the high-temperature raw material to be processed when the stretching roller 36 moves. When the fine spring 39 on the periphery of the slide bar 37 is compacted, the thrust of the movement of the sliding frame 33 plus the resilience of the fine spring 39 will cause the bracket 38 to push the block 311 into the stand 1, so that the bracket 38 can pop out to avoid affecting the continued calendering operation.
