Description

Technical Field

[0001] This utility model relates to the field of earmuff processing technology, specifically to a fixture for earmuff hot pressing processing. Background Technology

[0002] In consumer electronics and other fields, the demand for earmuffs is constantly increasing. The market requires earmuff manufacturers to improve production efficiency and shorten production cycles to meet rapidly changing market demands. Consumers have increasingly higher requirements for the wearing comfort and appearance quality of earmuffs. This necessitates that earmuff thermoforming fixtures ensure the precision and stability of thermoforming, so that the produced earmuffs meet high quality standards in terms of size, shape, and appearance. Therefore, it is necessary to develop an earmuff thermoforming fixture that can adapt to high-speed, mass production.

[0003] Previously, earmuff hot pressing often used manual fixtures, such as simple fixtures consisting of a mold core, mold frame, and pressure plate. Operators had to first visually center the earmuff skin on the upper part of the mold frame, then place the pressure plate for initial fixation, and finally align and press the mold core into the mold frame before sending it into the baking machine. This method relied entirely on manual operation, was cumbersome, inefficient, and could not meet the needs of large-scale mass production. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for hot pressing of earmuffs, which has the advantage of quickly positioning earmuffs and solves the problem of positioning deviation and large fluctuations in product quality caused by manual positioning of earmuffs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixture for hot pressing earmuffs, comprising a support mechanism, the support mechanism including a worktable, a driving mechanism being provided at the bottom of the worktable, and four grooves being provided at the top of the worktable, each groove having a positioning mechanism slidably connected therein, and a protruding plate being provided on one side of the top of the groove, and a scale plate being provided on the other side, the driving mechanism including a threaded rod one, a threaded rod two being helically engaged above the threaded rod one, and gear one being provided at both ends of the threaded rod one and the threaded rod two, and two driving rods two and driving rod one being symmetrically arranged above the threaded rod one and the threaded rod two, each of the driving rod one and the driving rod two being helically connected to the corresponding positioning mechanism.

[0006] Preferably, one side of the convex plate extends above the groove, the side of the scale plate facing the convex plate extends above the groove, and a gap is provided between the adjacent sides of the scale plate and the convex plate.

[0007] Preferably, each of the drive rods is provided with a gear three that meshes with the gear one at the end away from the center of the worktable, and the drive rod is provided with a thread one inside.

[0008] Preferably, each of the drive rods 2 is provided with a gear 4 that meshes with gear 1 at the end away from the center of the worktable, and the drive rod 1 is provided with a thread 2 that is opposite to the helical direction of thread 1. The diameter of gear 4 is greater than the diameter of gear 3.

[0009] Preferably, each of the positioning mechanisms includes a slider, the slider having a threaded hole that helically engages with the driving mechanism, and a limiting plate that fits the protruding plate and the scale plate at the top of the slider.

[0010] Preferably, the top of the limiting plate is provided with a support block extending out of the upper surface of the workbench, and an anti-slip post is provided at one end of the support block away from the center of the workbench. The side of the anti-slip post away from the support block is arc-shaped, and several anti-slip strips are horizontally provided on the side of the anti-slip post away from the support block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model, by setting up threaded rod one, threaded rod two, gear one, drive rod one, drive rod two, thread one, thread two, gear three, gear four, and positioning mechanisms, uses a servo motor to drive threaded rod one to rotate. Threaded rod one meshes with threaded rod two, causing threaded rod one and threaded rod two to rotate synchronously in opposite directions. Gear one meshes with gear three and gear four, causing drive rod one and drive rod two to rotate synchronously in opposite directions. Threads one and two, located on the outer edges of drive rod one and drive rod two, drive the four positioning mechanisms to move synchronously in opposite directions within the grooves. This expands the earmuff, replacing manual positioning, providing high positioning accuracy and fast positioning efficiency, improving the efficiency of earmuff processing, and ensuring stable earmuff quality.

[0013] 2. This utility model, by setting a limiting plate, a support block, an anti-slip column, and anti-slip strips, allows the earmuff to be attached to the side of the anti-slip column away from the center of the workbench. The friction between the anti-slip column and the earmuff is increased by several anti-slip strips horizontally set on the side of the anti-slip column, preventing the earmuff from falling off when it is opened.
