Description

Technical Field

[0001] This utility model relates to the field of medical mask technology, specifically a hot pressing molding device for the production of medical masks. Background Technology

[0002] Medical masks are key protective equipment used in medical settings to block the spread of pathogens. Hot pressing is a key process in the production of medical masks. Through the synergistic effect of high temperature and pressure, multiple layers of non-woven fabric (outer waterproof spunbond fabric, middle meltblown filter fabric, and inner skin-friendly spunbond fabric) are firmly bonded to components such as nose bridge strips and ear loops to form an ergonomic three-dimensional structure.

[0003] Regarding the above and existing related technologies: In the production of medical masks, it is necessary to heat press the medical masks. When using a hot press for processing, most materials lack limiting and cutting mechanisms, which can easily lead to material movement or inconvenience in cutting materials when multiple masks are produced together. Therefore, a hot pressing forming device for the production of medical masks is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The hot pressing forming device for medical mask production of this utility model includes a machine body and a supporting device. A hot pressing part is fixedly connected to the upper surface of the machine body, and an upper mold is fixedly connected to the bottom end of the hot pressing part. A lower mold is fixedly connected to the upper surface of the machine body. The supporting device is set on the upper surface of the machine body and includes a supporting frame. The supporting frame is located directly above the machine body. Two clamping rollers are rotatably connected to the surface of the supporting frame. A placement frame is fixedly connected to the side wall of the supporting frame. A main blade is fixedly connected to the surface of the placement frame. The material will drive the clamping rollers to rotate on the surface of the supporting frame. After hot pressing, the material is allowed to slide on the surface of the main blade on the placement frame. The supporting frame, clamping rollers, placement frame and main blade can limit the material and also facilitate the cutting of the material.

[0006] Preferably, a limiting block is fixedly connected to the upper surface of the machine body near the support frame. The limiting block is inserted into the inner surface of the support frame. When the support frame moves, the support frame will be fitted onto the surface of the limiting block, and the limiting block can restrict the position of the support frame.

[0007] Preferably, the inner wall of the support frame and the limiting block is threaded with two fixing pins. After the support frame is fitted onto the surface of the limiting block, the fixing pins are rotated to the inner wall of the support frame and the limiting block. The fixing pins can limit the position of the support frame on the surface of the limiting block.

[0008] Preferably, the inner wall of the placement rack is slidably connected to a slide bar, and a secondary blade is fixedly connected to the upper surface of the slide bar. The slide bar drives the secondary blade to move, and the secondary blade will squeeze the material onto the surface of the main blade. The arrangement of the slide bar and the secondary blade can facilitate the cutting of the material.

[0009] Preferably, multiple springs are fixedly connected to the bottom end of the slide bar and the surface of the placement frame. A push handle is provided on the side wall of the slide bar. When the slide bar slides, the slide bar drives the springs to contract. When the slide bar is in use, the springs will rebound. The springs are designed to drive the slide bar to slide.

[0010] Preferably, a cleaning device is provided between the upper mold and the lower mold. The cleaning device includes a hemisphere located directly above the lower mold. A fixing frame is fixedly connected to the side wall of the hemisphere, and a handle is fixedly connected to the end of the fixing frame away from the hemisphere. Adhesive tape is provided on the surface of the hemisphere. The hemisphere is inserted into the inner surface of the lower mold. By setting up the hemisphere, the fixing frame, and the handle, the adhesive tape can easily remove residual material.

[0011] Preferably, the mounting bracket and the surface of the hemisphere are fixedly connected to two reinforcing blocks. When the hemisphere is subjected to force, the hemisphere will transfer the force to the reinforcing blocks. The setting of the reinforcing blocks can make the hemisphere more stably installed on the mounting bracket.

[0012] Preferably, the upper surface of the hemisphere is provided with a storage groove, and the inner surface of the storage groove is provided with adhesive tape. Part of the upper mold structure is inserted into the inner surface of the storage groove. The storage groove facilitates the cleaning of the upper mold.

[0013] The advantages of this utility model are:

[0014] 1. When producing masks, this utility model involves pushing a support frame to fit onto the surface of a limiting block, then rotating a fixing pin to the inner wall of the support frame and the limiting block. The material is then passed through two clamping rollers. Before moving the material during production, a slide bar is pushed to cause a spring to contract. The slide bar slides on the inner wall of the placement frame, moving the secondary blade. As the material moves, the clamping rollers rotate on the support frame surface. After the material covers the lower mold surface, the hot pressing unit moves the upper mold, which presses the material into the inner surface of the lower mold. After hot pressing, the slide bar is pushed to move the secondary blade, which, along with the main blade, cuts the material. This device restricts the material's position and facilitates the separation of processed materials, thus simplifying subsequent material processing.

[0015] 2. When cleaning the upper and lower molds, this utility model involves attaching tape to the bottom of the hemisphere and the inner surface of the hemisphere's storage groove, then pushing the handle to move the fixing frame and the hemisphere. The hemisphere is inserted into the inner surface of the lower mold, where the tape will stick to the residue. Then, the hemisphere is moved to the upper mold, where the storage groove will fit over the surface of the upper mold, where the residue will stick to the groove. When the hemisphere is under force, the force is transmitted to the reinforcing block. By setting up the entire device, it is convenient to clean the upper and lower molds, reducing the amount of residue adhering to the surface of the mask. Attached Figure Description

[0024] Please see Figure 1-5 As shown, a thermoforming device for medical mask production, suitable for the production and processing of cup-shaped masks, specifically includes a machine body 1 and a support device 5. A thermoforming part 2 is fixedly connected to the upper surface of the machine body 1, and an upper mold 3 is fixedly connected to the bottom end of the thermoforming part 2. A lower mold 4 is fixedly connected to the upper surface of the machine body 1. The support device 5 is disposed on the upper surface of the machine body 1. The support device 5 includes a support frame 51, which is located directly above the machine body 1. Two clamping rollers 52 are rotatably connected to the surface of the support frame 51. A placement frame 53 is fixedly connected to the side wall of the support frame 51, and a main blade 54 is fixedly connected to the surface of the placement frame 53. During operation, the material is inserted between the two clamping rollers 52. As the material moves, it drives the clamping rollers 52 to rotate on the surface of the support frame 51. After thermoforming, the material slides on the surface of the main blade 54 on the placement frame 53. The support frame 51, clamping rollers 52, placement frame 53, and main blade 54 can limit the material and also facilitate the cutting of the material.

[0025] A limiting block 55 is fixedly connected to the upper surface of the body 1 near the support frame 51. The limiting block 55 is inserted into the inner surface of the support frame 51. During operation, the support frame 51 will be fitted onto the surface of the limiting block 55, and the limiting block 55 can restrict the position of the support frame 51.

[0026] The inner walls of the support frame 51 and the limiting block 55 are threadedly connected by two fixing pins 56. During operation, the fixing pins 56 are rotated to the inner walls of the support frame 51 and the limiting block 55, and the fixing pins 56 can limit the position of the support frame 51 on the surface of the limiting block 55.

[0027] The inner wall of the placement rack 53 is slidably connected to a slide bar 57, and a secondary blade 58 is fixedly connected to the upper surface of the slide bar 57. During operation, the slide bar 57 is pushed to slide on the inner wall of the placement rack 53, and the slide bar 57 drives the secondary blade 58 to move. The secondary blade 58 will squeeze the material onto the surface of the main blade 54. The arrangement of the slide bar 57 and the secondary blade 58 can facilitate the cutting of materials.

[0028] Multiple springs 59 are fixedly connected to the bottom end of the slide bar 57 and the surface of the placement rack 53. A push handle is provided on the side wall of the slide bar 57. When working, the slide bar 57 drives the springs 59 to retract. When using the slide bar 57, the springs 59 will rebound. The arrangement of the springs 59 can drive the slide bar 57 to slide.

[0029] A cleaning device 6 is provided between the upper mold 3 and the lower mold 4. The cleaning device 6 includes a hemisphere 61, which is located directly above the lower mold 4. A fixing frame 62 is fixedly connected to the side wall of the hemisphere 61. A handle 63 is fixedly connected to the end of the fixing frame 62 away from the hemisphere 61. Adhesive tape is provided on the surface of the hemisphere 61. During operation, the adhesive tape is stuck to the bottom of the hemisphere 61, and then the handle 63 is pushed to move the fixing frame 62 and the hemisphere 61. The hemisphere 61 is inserted into the inner surface of the lower mold 4. By setting up the hemisphere 61, the fixing frame 62 and the handle 63, the adhesive tape can easily pick up the residual material.

[0030] Two reinforcing blocks 64 are fixedly connected to the surfaces of the fixed frame 62 and the hemisphere 61. During operation, the hemisphere 61 transmits force to the reinforcing blocks 64. The reinforcing blocks 64 allow the hemisphere 61 to be more stably installed on the fixed frame 62.

[0031] The upper surface of the hemisphere 61 is provided with a storage groove 65, and the inner surface of the storage groove 65 of the hemisphere 61 is provided with adhesive tape. During operation, the adhesive tape is fixed to the inner surface of the storage groove 65. When the hemisphere 61 moves, part of the structure of the upper mold 3 will be inserted into the inner surface of the storage groove 65. The storage groove 65 makes it easy to clean the upper mold 3.

[0032] Working principle: When masks need to be produced, push the support frame 51 to fit onto the surface of the limiting block 55. Then rotate the fixing pin 56 to the inner wall of the support frame 51 and the limiting block 55. Then, the material passes through the two clamping rollers 52. Before the material is pulled during production, push the slide bar 57 to cause the spring 59 to contract. The slide bar 57 slides on the inner wall of the placement frame 53, and the slide bar 57 drives the auxiliary knife 58 to move. When the material moves, it will drive the clamping rollers 52 to rotate. The clamping rollers 52 rotate on the surface of the support frame 51. After the material covers the surface of the lower mold 4, the hot pressing part 2 drives the upper mold 3 to move. The upper mold 3 squeezes the material into the inner surface of the lower mold 4. After the hot pressing is completed, push the slide bar 57 to drive the auxiliary knife 58 to move. The auxiliary knife 58 and the main knife 54 will cut the material. The entire device is designed to restrict the position of materials and facilitate the separation of processed materials, thus simplifying subsequent material processing. When cleaning the upper mold 3 and lower mold 4 is required, tape is applied to the bottom of the hemisphere 61 and the inner surface of the storage groove 65 of the hemisphere 61. Then, the handle 63 is pushed to move the fixing frame 62 and the hemisphere 61, allowing the hemisphere 61 to insert into the inner surface of the lower mold 4. The tape will adhere to the residue. Then, the hemisphere 61 is moved to the upper mold 3, and the storage groove 65 will fit over the surface of the upper mold 3. The residue inside the storage groove 65 will adhere to the residue. When the hemisphere 61 is under force, it will transmit the force to the reinforcing block 64. By designing the entire device, it is possible to easily clean the upper mold 3 and lower mold 4, reducing the amount of residue adhering to the surface of the mask.
