Description

Technical Field

[0001] This utility model relates to the field of face mask production technology, specifically to a face mask leather positioning fixture structure. Background Technology

[0002] In the mask manufacturing industry, the positioning and forming of mask leather is a crucial step. Traditional methods for positioning mask leather often rely on simple clamps or manual operation. This method not only has low positioning accuracy, but also easily causes quality problems such as wrinkles and leakage during the mask leather forming process due to the compression and stretching of the mold, which seriously affects the quality of the finished mask and production efficiency.

[0003] Specifically, during the mask leather forming process, the leather needs to be stretched to fit the shape of the mold. However, because traditional positioning fixtures cannot effectively alleviate the tensile forces on the leather during forming, the leather is prone to wrinkles, deformation, or even damage after forming, thus affecting the mask's sealing and comfort. In addition, manual operation or the use of simple clamps increases the difficulty and labor intensity of operation, reducing production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mask leather positioning fixture structure, which solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mask leather positioning fixture structure, comprising a first frame and a second frame symmetrically arranged, the second frame being installed on both sides of the first frame, the first frame including a base, a slider being slidably connected to the upper part of the base; a limiting boss is fixed at the top of the base, a limiting channel is opened inside the limiting boss, a pin is movably arranged inside the limiting channel, the end of the pin is connected to the slider, and a spring is sleeved on the outside of the pin.

[0006] Furthermore, a first stop protrusion is fixed at the top of the base, and a slide is provided between the limiting protrusion and the first stop protrusion, and the slider slides inside the slide.

[0007] Furthermore, a second stop protrusion is connected to the tail end of the slider.

[0008] Furthermore, a cavity is provided in the middle of the slider, and the limiting boss is located inside the cavity.

[0009] Furthermore, the end of the pin is connected to a threaded post, and the slider has a threaded hole inside. The pin is connected to the slider through the matching threaded post and threaded hole.

[0010] Furthermore, the top of the first frame edge and the slider are each connected to several positioning protrusions, and the inside of the limiting channel is provided with stepped protrusions. The two ends of the spring abut against the pin and the stepped protrusions, respectively.

[0011] This utility model provides a positioning fixture structure for face mask leather. Compared with the prior art, it has the following advantages:

[0012] The positioning fixture structure for the face mask leather, through the linkage design of the slider and pin and the buffering effect of the spring, can automatically adjust the position of the slider according to the stress on the leather during the forming process. This effectively alleviates the tensile force caused by the forming and extrusion of the leather, thereby significantly reducing quality problems such as wrinkles and leakage after the face mask leather is formed, and improving the finished product quality and production efficiency of the face mask.

[0020] 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.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a mask leather positioning fixture structure, including a first frame 1 and a second frame 2 symmetrically arranged, the second frame 2 being installed on both sides of the first frame 1, the first frame 1 including a base 11, a slider 18 being slidably connected to the upper part of the base 11, a plurality of positioning protrusions 3 being connected to the top of the first frame 1 and the slider 18, a limiting boss 12 being fixed to the top of the base 11, a limiting channel 13 being opened inside the limiting boss 12, a pin 14 being movably arranged inside the limiting channel 13, the end of the pin 14 being connected to the slider 18, and a spring 15 being sleeved on the outside of the pin 14, a stepped protrusion 131 being provided inside the limiting channel 13, and the two ends of the spring 15 abutting against the pin 14 and the stepped protrusion 131 respectively;

[0022] The top of the base 11 is also fixed with a first stop protrusion 16. A slide 17 is reserved between the limiting protrusion 12 and the first stop protrusion 16, and the slider 18 slides inside the slide 17.

[0023] The tail end of the slider 18 is connected to the second stop protrusion 19. When the slider 18 slides outward to the maximum displacement, the first stop protrusion 16 and the second stop protrusion 19 abut against each other.

[0024] A cavity 110 is formed in the middle of the slider 18, and the limiting boss 12 is located inside the cavity 110. The cavity 110 and the slide rail 17 can work together to improve the sliding stability of the slider 18.

[0025] The end of the pin 14 is connected to the threaded post 141. The slider 18 has a threaded hole 181 inside. The pin 14 is connected to the slider 18 through the matching threaded post 141 and threaded hole 181. When assembling the pin 14, first put the spring 15 on the outside of the pin 14, and then insert the entire pin 14 and spring 15 into the inside of the limiting channel 13. After insertion, rotate the pin 14 so that the threaded post 141 is screwed into the threaded hole 181. After being screwed in, the two ends of the spring 15 will abut against the pin 14 and the stepped protrusion 131.

[0026] When positioning the face mask material, the fixture first uses the positioning holes 41 inherent on the edge of the face mask material 4 to fix the face mask material 4 to each positioning protrusion 3 of the first frame edge 1 and the second frame edge 2, thus completing the fixation. After fixation, the material needs to be formed into a face mask, which requires a forming mold. The fixture is fixed on the lower forming mold, and the upper and lower forming molds press together on the face mask material 4. After the face mask material 4 is subjected to force, it will pull the slider 18 to slide. Because the slider 18 is fixedly connected to the pin 14, the sliding of the slider 18 will drive the pin 14 to slide synchronously. Also, because the two ends of the spring 15 abut against the pin 14 and the stepped protrusion 131, the spring 15 will be compressed and contracted during the sliding of the pin 14. That is, the displacement of the slider 18 is used to relieve the tensile force generated when the face mask material 4 is pressed during the forming process.

[0027] The final effect is that when the mask material 4 is formed, the upper mold presses down on the mask material 4. At this time, the mask material 4 drives the slider 18 to move towards the middle, reducing the stretching of the mask material 4, thus reducing damage to itself and improving quality problems such as wrinkles and leakage.

[0028] Once the face mask material 4 is formed, the upper mold is lifted and detached from the face mask material 4. The previously contracted spring 15 will push the push pin 14 back to its original position, thereby driving the slider 18 to reset synchronously. Then, the formed face mask material 4 can be removed.
