Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, specifically a sealing machine with a safe cutting mechanism. Background Technology

[0002] A sealing machine is a device used to seal bags, packaging materials, etc. It is widely used in many fields. However, the cutting mechanism of traditional sealing machines does not have a good blade hiding mechanism, which means that the blade is exposed in the working or non-working state, which can easily cause operators to accidentally touch and cut themselves. In addition, the replacement of existing sealing machine blades is relatively cumbersome after they wear out. At the same time, after sealing and cutting packaging materials, residual packaging waste will be scattered on the table or the ground, which is not easy to clean up. To solve the above problems, a sealing machine with a safe cutting mechanism is needed.

[0003] Existing sealing machines lack effective cutting protection measures during operation. The cutting area is often completely exposed, which can easily lead to accidental contact or cuts. The cutting blade installation structure is complex, requiring operators to use various professional tools and go through tedious disassembly steps to remove the old blade and replace it with a new one, resulting in a significant decrease in production efficiency and an increase in production costs. After the sealing and cutting operations are completed, the sealing machine generates a large amount of packaging waste, such as excess packaging film and scraps, which causes the waste to be scattered randomly, affecting the cleanliness of the working environment and potentially interfering with subsequent production operations. Therefore, there is an urgent need for a sealing machine with a safe cutting mechanism. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a sealing machine with a safe cutting mechanism to solve the problems of existing sealing machines, such as the lack of effective cutting protection measures, the fact that the cutting operation area is often completely exposed, which can easily cause accidental contact or cuts, the complex installation structure of the cutting blades, which requires operators to use a variety of professional tools and go through cumbersome disassembly steps to remove the old blades and replace them with new ones, resulting in a significant decrease in production efficiency and an increase in production costs, and the large amount of packaging waste generated after the sealing and cutting operations, such as excess packaging film and scraps, which causes waste to be scattered randomly, affecting the cleanliness of the working environment and potentially interfering with subsequent production operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealing machine with a safe cutting mechanism, comprising a base, an adjustment key installed on the side wall of the base, a heating strip installed on the top of the base, limit grooves formed on both sides of the top of the base, a limit rod installed on the inner wall of the limit groove, a limit spring installed on the outer wall of the limit rod, a pressure plate installed on the top of the limit spring, a storage sleeve installed on the side wall of the pressure plate, a rotating shaft installed on the inner wall of the storage sleeve, a cover plate installed on the outer wall of the rotating shaft, a top spring installed on the inner wall of the cover plate, and a top rod installed on the outer wall of the top spring.

[0006] A fixing rod is installed on the inner wall of the storage sleeve, a blade is installed on the outer wall of the fixing rod, and a fixing sleeve is installed on the outer wall of the blade.

[0007] The base has a card plate installed on its side wall, a waste bin installed on the outer wall of the card plate, a slot opened on the inner wall of the waste bin, and a protective plate installed on the inner wall of the slot.

[0008] Preferably, the pressure plate is movably connected to the limiting rod, and the pressure plate and the limiting rod form a telescopic structure through the limiting spring.

[0009] Preferably, the cover plate forms a rotating structure with the storage sleeve via a rotating shaft, and the top rod forms a telescopic structure with the cover plate via a top spring.

[0010] Preferably, the top rod is symmetrically arranged with the central axis of the cover plate as the center, and the top rod is engaged with the storage sleeve.

[0011] Preferably, the blade is sleeved with the fixing rod, and the fixing sleeve is threadedly connected to the fixing rod.

[0012] Preferably, the retaining sleeve fits tightly against the blade, and the inner wall of the blade has an open design.

[0013] Preferably, the waste bin is connected to the card plate by a card slot, and the protective plate is inserted into the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of a storage sleeve, a rotating shaft, a cover plate, a top spring, a top rod, a blade, a slot, and a protective plate, presses the top rod inward, and then rotates the cover plate around the rotating shaft to close the cover plate with the storage sleeve. At this time, the top rod is pushed out by the elastic force of the top spring, so that the top rod is locked and fixed with the storage sleeve, thereby blocking the blade. At the same time, the protective plate is inserted into the slot to prevent the operator's fingers from accidentally sticking into the bottom of the blade and causing cuts during sealing and cutting. The combined use of the cover plate and the protective plate improves the safety of blade cutting operations.

[0016] 2. This utility model uses a fixed rod, a blade, and a fixed sleeve to connect the blade to the fixed rod, and then the fixed sleeve is threaded to the fixed rod. The cooperation between the fixed rod and the fixed sleeve allows the blade to be changed quickly, improving processing efficiency.

[0017] 3. This utility model uses a card plate, a waste bin, and a slot to fix the waste bin to the card plate. The waste bin allows excess waste material to fall directly into the waste bin, preventing waste from splashing and being difficult to clean, thus ensuring a clean and tidy working environment.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] Please see Figure 1-6A sealing machine with a safety cutting mechanism includes a base 1, an adjustment key 2 installed on the side wall of the base 1, a heating strip 3 installed on the top of the base 1, limit grooves 4 on both sides of the top of the base 1, limit rods 5 installed on the inner wall of the limit grooves 4, limit springs 6 installed on the outer wall of the limit rods 5, a pressure plate 7 installed on the top of the limit springs 6, a storage sleeve 8 installed on the side wall of the pressure plate 7, a rotating shaft 9 installed on the inner wall of the storage sleeve 8, a cover plate 10 installed on the outer wall of the rotating shaft 9, a top spring 11 installed on the inner wall of the cover plate 10, and a top rod 12 installed on the outer wall of the top spring 11. The pressure plate 7 and the limit rods 5 are movably connected, and the pressure plate 7 and the limit rods 5 form a telescopic structure through the limit springs 6 and 5. The cover plate 10 and the storage sleeve 8 form a rotating structure through the rotating shaft 9, and the top rod 12 is connected to the top springs 6 and 5. The cover plate 10 and the cover plate 11 form a telescopic structure. The top rod 12 is symmetrically arranged around the central axis of the cover plate 10 and is engaged with the storage sleeve 8. Through the storage sleeve 8, the rotating shaft 9, the cover plate 10, the top spring 11, the top rod 12, the blade 14, the slot 19, and the protective plate 20, the top rod 12 is pressed inward, and then the cover plate 10 is rotated around the rotating shaft 9 to close the cover plate 10 and the storage sleeve 8. At this time, the top rod 12 is pushed out by the elastic force of the top spring 11, so that the top rod 12 is engaged and fixed with the storage sleeve 8, thereby blocking the blade 14. At the same time, the protective plate 20 is inserted into the slot 19 to prevent the operator's fingers from accidentally sticking into the bottom of the blade 14 and causing cuts during sealing and cutting. The combined use of the cover plate 10 and the protective plate 20 improves the safety of the blade 14 during cutting operations.

[0028] Please see Figure 1-6 A sealing machine with a safe cutting mechanism is disclosed. A fixing rod 13 is installed on the inner wall of a storage sleeve 8, a blade 14 is installed on the outer wall of the fixing rod 13, and a fixing sleeve 15 is installed on the outer wall of the blade 14. The blade 14 is sleeved with the fixing rod 13, and the fixing sleeve 15 is threadedly connected to the fixing rod 13. The fixing sleeve 15 and the blade 14 fit tightly together, and the inner wall of the blade 14 is designed with an opening. By setting the fixing rod 13, the blade 14 and the fixing sleeve 15, the blade 14 is sleeved with the fixing rod 13, and then the fixing sleeve 15 is threadedly fixed to the fixing rod 13. The cooperation of the fixing rod 13 and the fixing sleeve 15 allows the blade 14 to be quickly replaced, improving processing efficiency.

[0029] Please see Figure 1-6A sealing machine with a safe cutting mechanism is provided. A clamping plate 16 is installed on the side wall of the base 1. A waste bin 17 is installed on the outer wall of the clamping plate 16. A slot 18 and a groove 19 are opened on the inner wall of the waste bin 17. A protective plate 20 is installed on the inner wall of the groove 19. The waste bin 17 is engaged with the clamping plate 16 through the slot 18. The protective plate 20 is inserted into the groove 19. Through the clamping plate 16, the waste bin 17 and the slot 18, the waste bin 17 is engaged and fixed with the clamping plate 16 through the slot 18. The waste bin 17 is designed so that the excess waste material cut is directly dropped into the waste bin 17, avoiding waste splashing and difficulty in cleaning, and ensuring a clean and tidy working environment.

[0030] Working principle: In use, first move the device to the desired position, then connect the blade 14 to the fixing rod 13, and then thread the fixing sleeve 15 onto the fixing rod 13. The cooperation of the fixing rod 13 and the fixing sleeve 15 allows for quick replacement of the blade 14. Next, press the top rod 12 inwards, and then rotate the cover plate 10 around the rotating shaft 9 to close the cover plate 10 and the storage sleeve 8. At this time, the top rod 12 is pushed out by the elastic force of the top spring 11, causing the top rod 12 to engage and fix with the storage sleeve 8, thereby blocking the blade 14. Simultaneously, insert the protective plate 20 into the slot 19 to prevent damage during sealing and cutting. If an operator accidentally inserts their finger into the bottom of the blade 14, causing a cut, the waste bin 17 is then secured to the plate 16 via the slot 18. The waste bin 17 is designed so that excess waste material falls directly into it, preventing waste from splashing and making it difficult to clean, thus ensuring a clean and tidy working environment. Finally, the packaging bag to be sealed is placed above the heating strip 3, and pressure is applied downwards to the pressure plate 7. While sealing the packaging bag, the blade 14 cuts off the excess material. This completes the process of using the device.
