Description

Technical Field

[0001] This application relates to the field of sealant preparation equipment, and more particularly to a sealant hardness sheet preparation apparatus. Background Technology

[0002] The hardness of silicone sealant is a key parameter for balancing elasticity, strength, and durability. The preparation of silicone sealant hardness test sheets is a crucial step in evaluating its performance (such as Shore hardness).

[0003] In conventional production of hardness sheets, each sheet needs to be made individually, which is very inefficient, especially when mass production is carried out. PE film or aluminum film is often used as the carrier of the hardness sheet. However, aluminum film is light and can easily be displaced when the mold frame is removed due to the adhesion of the adhesive to the mold frame, causing deformation of the hardness sheet and pollution of the surrounding operating environment. Utility Model Content

[0024] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0026] The hardness of silicone sealant is a key parameter for balancing elasticity, strength, and durability. The preparation of silicone sealant hardness test sheets is a crucial step in evaluating its performance (such as Shore hardness).

[0027] In conventional production of hardness sheets, each sheet needs to be made individually, which is very inefficient, especially when mass production is carried out. PE film or aluminum film is often used as the carrier of the hardness sheet. However, aluminum film is light and can easily be displaced when the mold frame is removed due to the adhesion of the adhesive to the mold frame, causing deformation of the hardness sheet and pollution of the surrounding operating environment.

[0028] To address the issues of low efficiency and easy deformation of hardness sheets due to repetitive operations during batch production, this application provides a sealant hardness sheet preparation apparatus.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses an apparatus for preparing sealant hardness sheets. (Refer to...) Figure 1 , Figure 2 A sealant hardness sheet preparation device includes a horizontally arranged support base 1. The top wall of the support base 1 is a horizontal plane and an aluminum film 2 is placed above the support base 1 to support the hardness sheet. The aluminum film 2 can move along the length of the support base 1 on the upper surface of the support base 1. The aluminum film 2 supports the hardness sheet located above the aluminum film 2, which facilitates the movement of the formed hardness sheet.

[0031] A pressure frame 3 is horizontally arranged above the support base 1. The pressure frame 3 is located above the aluminum film 2 of the support base 1. The pressure frame 3 is located on the side of the support base 1 close to the support base 1 along the width direction and is hinged to the support base 1. This allows the pressure frame 3 to be flipped on the support base 1. When the pressure frame 3 is flipped up, the aluminum film 2 can move on the upper surface of the support base 1. When the pressure frame 3 is in a horizontal state, it can press the aluminum film 2 tightly, reducing the movement of the aluminum film 2 and facilitating the forming operation of the hard sheet.

[0032] Reference Figure 2 , Figure 3 The pressure frame 3 includes two opposing first pressure rods 31 arranged along the length of the support base 1. Second pressure rods 32 are respectively located at the ends of the two opposing first pressure rods 31, arranged along the width of the support base 1. The two ends of the second pressure rods 32 are fixedly connected to the two first pressure rods 31, and the first pressure rods 31 and second pressure rods 32 are perpendicular to each other. A rectangular frame structure is formed by the two opposing first pressure rods 31 and the two opposing second pressure rods 32, and a hollow operating space 33 is formed between the two opposing first pressure rods 31 and the two opposing second pressure rods 32 for shaping the hardness sheet.

[0033] A cutting assembly 34 is also provided above the first pressure rod 31 of the pressure frame 3. The cutting assembly 34 is used to cut the aluminum film 2 located below the first pressure rod 31, so as to facilitate the movement of the formed hard sheet through the aluminum film 2.

[0034] Reference Figure 2 , Figure 4 The cutting assembly 34 includes a cutting housing 341, which is fixedly connected to the first pressure rod 31. The cutting housing 341 is a box structure with an open bottom and a hollow interior. A cutting blade 342 is vertically arranged inside the cutting housing 341, with its cutting surface facing downwards. A cutting opening 311 is provided on the surface of the first pressure rod 31 relative to the cutting blade 342, allowing the cutting blade 342 to pass through and cut the aluminum film 2 located below the first pressure rod 31 by extending from inside the cutting opening 311. The length of the cutting blade 342 along the width direction of the support base 1 is greater than the width of the aluminum film 2, and both ends of the cutting blade 342 are at least located at the width edge of the aluminum film 2, facilitating the cutting of the aluminum film 2 by the cutting blade 342.

[0035] A support plate 343 is fixedly connected to the top of the cutting blade 342. The support plate 343 is located inside the cutting housing 341 and is slidably connected to the cutting housing 341. A spring 344 is vertically arranged below the support plate 343. One end of the spring 344 is fixedly connected to the support plate 343, and the other end is fixedly connected to the first pressure rod 31. When the spring 344 is fully compressed, the bottom cutting surface of the cutting edge 311 of the cutting blade 342 extends out to cut the aluminum film 2 located below the first pressure rod 31. When the spring 344 is in a free state, the support plate 343 drives the cutting blade 342 to be completely inside the cutting housing 341, reducing the risk of injury to the operator from the exposed cutting blade 342. An operating rod 345 is vertically mounted at the top of the support plate 343. The operating rod 345 is fixedly connected to the support plate 343, and its top end extends from the top wall of the cutting housing 341. The operating rod 345 is slidably connected to the cutting housing 341. A cutting pre-cutting opening is vertically provided on the support base 1 at a position relative to the cutting blade 342. The cutting pre-cutting opening provides a pre-cutting position for the cutting blade 342 to facilitate the cutting of the aluminum film by the cutting blade 342.

[0036] Reference Figure 2 , Figure 3 A hardness sheet forming frame 4 is provided inside the operating space 33 of the pressure frame 3. The hardness sheet forming frame 4 is hinged to the support base 1 on the side near the pressure frame 3 that is hinged to it. The hardness sheet forming frame 4 includes a forming plate 41, which is a rectangular plate and is located inside the operating space 33 of the pressure frame 3. A forming hole 42 is vertically formed on the forming plate 41, which completely penetrates the forming plate 41 and is in communication with the interior of the operating space 33. Multiple forming holes 42 are arranged sequentially along the length of the support base 1, and there is a gap between adjacent forming holes 42. In some embodiments, the forming hole 42 is a rectangular hole, and in other embodiments, the forming hole 42 can be adapted to the shape of the required hardness sheet.

[0037] A pull ring 43 is also fixedly connected to the side wall of the hardness plate forming frame 4. The pull ring 43 is located on the side away from the hardness plate forming frame 4 and the support base 1. The bottom wall height of the pull ring 43 is higher than the top wall height of the pressure frame 3, so that the pull ring 43 is located above the pressure frame 3, making it convenient for the operator to pull the hardness plate forming frame 4 out of the operating space 33 through the pull ring 43.

[0038] The top wall of the hardening sheet is also covered with an anti-stick layer, which is used to reduce the adhesion between the hardening sheet and the hardening sheet caused by overflow during the filling process.

[0039] The implementation principle of the sealant hardness sheet preparation device in this application embodiment is as follows: First, open the pressure frame 3 and the hardness sheet forming frame 4 in sequence, lay the aluminum film 2 flat on the support base 1, put down the pressure frame 3, press the aluminum film 2, put down the hardness sheet forming frame 4, inject glue into the forming hole 42 of the hardness sheet forming frame 4, scrape off the excess glue with a spatula, use a plastic knife to separate the sample from the frame, press the cutting blades 342 on both sides of the pressure frame 3 to cut the aluminum film 2.

[0040] First, lift the hardness sheet forming frame 4, then lift the pressure frame 3. Remove the aluminum film 2 and the hardness sheet sample, and allow them to cure.
