Description

Technical Field

[0001] The present invention relates to the technical field of thermoforming machines, and more specifically, it relates to a thermoforming machine for processing corner mirrors. Background Art

[0002] At present, transportation roads extend in all directions and vehicles shuttle back and forth, which is the current traffic situation in each town. However, transportation roads are not straight paths, and there are certain blind spots in the line of sight when vehicles drive at corners and intersections, posing potential hazards to driving safety; due to its wide radiation surface, a wide-angle convex mirror installed at a road corner or intersection can provide a wider viewing field for drivers, facilitating drivers to observe the road and traffic flow conditions and improving driving safety.

[0003] Corner mirrors are made by thermoforming PC sheets using a thermoforming machine. After the existing thermoforming machine thermoforms the PC sheet into a corner mirror, the sheet is taken out of its body manually. This method is very inconvenient, and the just-formed corner mirror has a high temperature, which may easily cause burns to workers. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a thermoforming machine for processing corner mirrors with a reasonable and simple structure, strong practicability, and capable of automatically sending out the processed corner mirrors.

[0015] Figure 2 It is an installation schematic diagram of the ejection device. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Referring to Figures 1 to 2 The embodiments of the present invention will be further described.

[0017] The specific structure of this embodiment: includes an equipment body, the equipment body has a workbench 1, a base frame for placing sheet materials is arranged on the workbench 1, adsorption holes 30 are formed on the base frame, a heating component 2 for heating the sheet materials is horizontally slidably arranged on the workbench 1, and a suction fan 10 for stretching the sheet materials into the adsorption holes 30 during heating is arranged on the workbench 1.

[0018] The heating component 2 is a common sheet material heater on the market, and its own heating plate is heated by being powered on. The heating component 2 and the frame on the workbench 1 are connected by installing slidable tracks. When the sheet materials need to be heated, a cylinder or a motor controls the heating component 2 to displace to the directly above the sheet materials.

[0019] When the heating component 2 heats the sheet, the sheet will be softened, and then the air extractor 10 extracts air. The sheet above the adsorption holes 30 will move downward toward the adsorption holes 30. The adsorption holes 30 serve as a mold, and finally the sheet changes from a flat plate to a structure with a convex mirror.

[0020] The base frame includes a material plate 3 and a frame placed on the material plate 3. The material plate 3 and the frame are detachably connected. The adsorption holes 30 are placed on the material plate 3. The frame includes an outer frame 41 and an inner frame 42. The inner frame 42 is placed inside the outer frame 41 and is slidably connected to the outer frame 41. Graphite strips for reducing the friction generated when the two slide are provided on the end faces of the inner frame 42 and the outer frame 41 that are in contact with each other. A number of positioning holes connected to each other are provided on both the outer frame 41 and the inner frame 42.

[0021] The inner frame 42 has a card slot for inserting the sheet. The workbench 1 is provided with an ejection device for ejecting the sheet inside the inner frame 42.

[0022] The ejection device is used to automatically separate the formed corner mirror from the inner frame 42. Its specific structure: includes a movable part and a fixed part. The movable part includes tension springs 51 placed on both sides of the outer frame 41 and a push-pull cylinder 52 for driving the inner frame 42 to move relative to the outer frame 41.

[0023] The fixed part: includes a static fixing unit for locking the position of the inner frame 42 when it moves backward and a dynamic fixing unit placed on the moving path of the inner frame 42 and used to limit the inner frame 42 from continuing to move forward.

[0024] The static fixing unit includes: a lifting cylinder 61 and a positioning pin rod 62. The positioning pin rod 62 is connected to the output end of the lifting cylinder 61. The lifting cylinder 61 controls the positioning pin rod 62 to extend into the positioning hole to fix the position of the inner frame 42.

[0025] The dynamic fixing unit includes a collision-resistant platform 71 fixed on the workbench 1. A rubber pad is provided on the end face of the collision-resistant platform 71 for receiving the impact of the inner frame 42. The inner frame also has a collision-resistant rubber pad 421.

[0026] Sliding openings are provided on the side of the outer frame 41. Both sides of the inner frame 42 have connecting parts 420 extending out of the sliding openings. The workbench 1 is provided with a connecting rod 11. The connecting rod 11 and the connecting part 51 are on the same axis. One end of the tension spring 51 is connected to the connecting part and the other end is connected to the connecting rod.

[0027] Specific working principle: Before the corner mirror made of PC material in the thermoforming machine, the sheet is inserted into the card slot of the inner frame 42 (the width of the card slot is greater than the thickness of the sheet), and then the inner frame 42 is pushed and pulled by the push-pull cylinder 52 to slide backward, that is, to move forward into the outer frame 41. During this process, the tension spring 51 is stretched along with the moving direction of the inner frame 42. When the sheet reaches the set position, the lifting cylinder 61 drives the positioning pin rod 62 to move towards the outer frame 41, so that the positioning pin rod 62 passes through the positioning hole of the outer frame 41 and at the same time penetrates into the positioning hole of the inner frame 42 to complete the locking of the position of the inner frame 42; then the push-pull cylinder 52 controls its output end to return to the initial state; then the heating component 2 heats the sheet and cooperates with the suction fan 10 and the adsorption holes 30 to form the sheet.

[0028] After the sheet is formed, the lifting cylinder 61 controls the positioning pin rod 62 to quickly withdraw from the positioning hole. Affected by the elastic recovery ability of the tension spring 51, the inner frame 42 will be quickly pulled forward until the inner frame 42 hits the anti-collision platform 71. When it hits the anti-collision platform 71, due to inertia, the sheet on the inner frame 42 will fly out of its card slot. For convenient storage, a storage net is arranged on the path where the sheet is ejected and flies out.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
