Technical Field

[0001] This utility model relates to the field of tissue paper cutting, specifically a non-stick tissue paper hot-cutting die. Background Technology

[0002] A tissue hot-cutting die is a mold specifically designed for cutting tissues and other paper materials. It uses hot-cutting technology, heating the blade to a certain temperature to quickly and accurately cut the paper. This die is usually made of hard alloy to ensure sufficient strength and durability during use. Tissue hot-cutting dies can greatly improve the production efficiency and quality of tissues and other paper products.

[0003] Chinese patent CN208930461U discloses a blister packaging die, including a cutting groove. A die groove runs through the lower part of the fixed crossbar near the middle of the cutting groove. A positioning rod is fixedly installed on the front outer surface of the fixed frame. This device uses a die groove to facilitate cutting and reduce damage to the item and the die, making cutting more convenient and precise, while also improving the service life of the die. The fixing hole allows the staff to better place the blister packaging in the center according to its size, which further facilitates cutting and makes it more convenient for the staff to use.

[0004] During the use and storage of the aforementioned blister packaging die, the cutting area is often exposed. In order to prevent the metal at the cutting area from colliding with hard objects and being damaged during storage, an additional protective structure is required. However, the protective structure will cause the die to have a large protruding position, which will affect storage and organization. Utility Model Content

[0005] The purpose of this utility model is to provide a non-stick tissue box hot-cutting die. Protective plates are fixed to both ends of the outer frame. Fixing rods are inserted into the second fixing hole and the first fixing hole respectively and rotated. After rotation, the fixed position of the protective plates can support the fixing plate and protect the blade of the fixing plate, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a non-stick tissue box hot-cutting die, comprising a fixing plate, a blade welded to the front end of the fixing plate, an outer frame surrounding the fixing plate, a pair of sliding rails arranged laterally at both the upper and lower ends of the outer frame, a first fixing hole at the front end of the sliding rail, a second fixing hole at the rear end of the sliding rail, a protective plate at the rear end of the fixing plate, and a pair of fixing rods rotatably arranged at both the upper and lower ends of the protective plate. The protective plate is installed in the corresponding orientation according to usage requirements, and the protective plate is inserted into the corresponding first and second fixing holes through the fixing rods.

[0007] Preferably, an extension strip is welded to one side of the outer side of the fixing rod, a first movable cavity is provided at the upper end of the first fixing hole, and a second movable cavity is provided at the upper end of the second fixing hole. After the extension strip is inserted into the outer frame through the second movable cavity and the first movable cavity, it can be rotated to fix the protective plate, so that the protective plate wraps and protects the fixing plate.

[0008] Preferably, the lower end of the first fixing hole is recessed towards the middle of the outer frame, and the lower end of the second fixing hole is recessed towards the middle of the outer frame, and the fixing rod can be rotated within the extension strip to be inserted into the first and second limiting grooves respectively. After being inserted into the first and second limiting grooves respectively, the fixing rod can be restricted.

[0009] Preferably, the protective plate has a recessed protective groove on the side facing the blade, and the inside of the protective groove is connected to the external slot of the blade. After the protective plate moves toward the blade, the blade can be inserted into the protective groove for storage.

[0010] Preferably, the inside of the protective groove is coated with lubricant, which allows the lubricant to be wrapped around and covered on the outside of the blade when it is embedded in the protective groove.

[0011] Preferably, both the upper and lower ends of the fixed plate are embedded in the sliding rail and slidably connected to the inside of the sliding rail. The position of the blade can be adjusted by sliding the fixed plate in the position of the sliding rail inside the outer frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When the blade is pressed and in contact with the paper for cutting, the protective plate, through the restriction of the extension strip and the support of the fixing rod, allows the protective plate to abut against the rear end of the fixing plate, fixing the fixing plate and allowing the blade at the front end of the fixing plate to protrude from the front end of the outer frame. During daily storage, the fixing plate slides along the sliding rail into the inner part of the outer frame, and the protective plate wraps around the blade through the internal reserved protective groove, providing comprehensive protection for the blade. The protective groove is filled with lubricant, which can be applied to the blade surface when the blade is inserted into the protective groove, preparing the blade for the next cut and preventing subsequent cuts from sticking to the item.

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, a non-stick tissue paper hot-cutting die of this embodiment includes a fixing plate 2. A cutting blade 3 is welded to the front end of the fixing plate 2. After being fixed, the blade 3 cuts the tissue paper to complete the processing of the tissue paper.

[0026] In order to facilitate the adjustment and protection of the blade 3 and the fixing plate 2, the fixing plate 2 is surrounded by an outer frame 1. The upper and lower ends of the outer frame 1 are horizontally provided with a pair of sliding rails 9. The upper and lower ends of the fixing plate 2 are embedded in the sliding rails 9 and slidably connected to the inside of the sliding rails 9. The fixing plate 2 can adjust the position of the blade 3 by sliding along the sliding rails 9. Adjusting the position of the blade 3 is to facilitate the storage and use of the blade 3.

[0027] In addition, such as Figure 2 , Figure 3 and Figure 4As shown, the front end of the sliding rail 9 is provided with a first fixing hole 4, and the rear end of the sliding rail 9 is provided with a second fixing hole 10. The center positions of the second fixing hole 10 and the first fixing hole 4 overlap, and the second fixing hole 10 and the first fixing hole 4 have the same diameter. The rear end of the fixing plate 2 is provided with a protective plate 6. The upper and lower ends of the protective plate 6 are provided with a pair of fixing rods 7. When the protective plate 6 is slidably placed into the outer frame 1, the fixing rods 7 will move towards the outer frame 1 along with the protective plate 6. The fixing rods 7 will be inserted into the corresponding second fixing hole 10 and first fixing hole 4, which facilitates the fixing of the protective plate 6.

[0028] To facilitate the fixing of the protective plate 6 and the fixing plate 2, an extension strip 8 is provided on one side of the fixing rod 7. The extension strip 8 is welded and fixed to the fixing rod 7. Figure 5 and Figure 6 As shown, the upper end of the first fixing hole 4 is provided with a first movable cavity 5, and the upper end of the second fixing hole 10 is provided with a second movable cavity 11. When the fixing rod 7 is inserted into the corresponding second fixing hole 10 and first fixing hole 4, the fixing rod 7 will insert the extension strip 8 into the second movable cavity 11 and the first movable cavity 5. When fixing the insertion position of the fixing rod 7, the fixing rod 7 needs to be rotated. The outside of the fixing rod 7 is rotatably connected to the through position of the protective plate 6. After the fixing rod 7 drives the extension strip 8 to be inserted into the corresponding position, the extension strip 8 will rotate away from the second movable cavity 11 and the first movable cavity 5, thereby preventing the fixing rod 7 from falling off.

[0029] In order to allow the extension strip 8 to rotate smoothly and thus fix the protective piece 6 in the required position, such as... Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the lower end of the first fixing hole 4 is recessed towards the middle of the outer frame 1, and the lower end of the second fixing hole 10 is recessed towards the middle of the outer frame 1, and the second fixing hole 10 is recessed towards the middle of the outer frame 1, and the second fixing hole 14 is located at the lower end of the sliding rail 9. When the fixing rod 7 is inserted into the second fixing hole 10, the extension bar 8 is directly retained in the sliding rail 9 by rotation, and directly abuts against the rear end of the fixing plate 2 by the fixing rod 7, which is used to fix the fixing plate 2 and the blade 3 at the front end of the fixing plate 2. After the fixing rod 7 is inserted into the first fixing hole 4, it will be embedded into the first fixing hole 13 by rotation, thereby fixing the protective piece 6.

[0030] To facilitate the storage of the blade 3 and to protect the blade 3, a protective groove 12 is recessed on the side of the protective plate 6 facing the blade 3. The inside of the protective groove 12 is connected to the external slot of the blade 3. When the fixing rod 7 is inserted into the first fixing hole 4 and fixed in the position of the first fixing hole 4, the blade 3 will be embedded in the protective groove 12 and protected.

[0031] In order to enable the blade 3 to cut the tissue paper quickly and avoid the blade 3 sticking to the tissue paper during the cutting process, the blade 3 is heated during the cutting process. At the same time, the inside of the protective groove 12 is coated with lubricant, which can stick to the surface of the blade 3 when the blade 3 is embedded in the protective groove 12.

[0032] Working principle: When using the die-cutting mold to cut the tissue paper, the fixing plate 2 slides within the sliding rail 9, near the end of the first fixing hole 4. The protective piece 6 is inserted into the rear end of the outer frame 1, facing the rear end of the fixing plate 2. The fixing rod 7 drives the extension strip 8 to be inserted into the corresponding second fixing hole 10 and the second movable cavity 11 respectively. After rotating the fixing rod 7, the extension strip 8 is embedded into the second limiting groove 14, fixing the protective piece 6 and the fixing plate 2 against which the protective piece 6 is attached. After the bolts pass through the four corners of the outer frame 1 and fix it in the position for cutting, the tissue paper comes into contact with the blade 3. After cutting is completed, when storing and protecting the blade 3, the fixing plate 2 slides in the sliding rail 9 and approaches one end of the second movable cavity 11. The protective plate 6 flips over and moves from the protective groove 12 toward the blade 3, so that the blade 3 is finally embedded in the protective groove 12. The fixing rod 7 and the second limiting groove 14 connected to the protective plate 6 extend into the corresponding first fixing hole 4 and first movable cavity 5, respectively. Rotating the fixing rod 7 causes the extension strip 8 to rotate in the first limiting groove 13. The protruding extension strip 8 will be fixed in the first limiting groove 13 to limit and protect the blade 3.
