DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0026] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications also change accordingly.

[0027] The utility model provides a cutting knife heat shrinkage packaging mechanism.

[0028] In the embodiment, with reference to Figures 1-4 The cutting knife heat shrinkage packaging mechanism comprises a pair of clamping assemblies 1 arranged opposite to each other, the pair of clamping assemblies 1 comprises a fixed support plate 2, a push device 3 fixed on the fixed support plate 2, a push plate 4 connected with the output end of the push device 3, and clamping ring one 5 and clamping ring two 6 arranged on the push plate 4, the clamping ring one 5 and the clamping ring two 6 are both provided with a hot gas inlet 7 and a hot gas outlet 8 in communication, and the clamping ring one is further provided with a clamping groove 9.

[0029] In the above technical solution, the pair of clamping assemblies arranged opposite to each other are provided, the pair of clamping assemblies comprises a fixed support plate, a push device, a push plate, and clamping ring one and clamping ring two on the push plate, in addition, the hot gas inlet and outlet are arranged on the clamping ring, and the clamping groove is arranged on the clamping ring one, so that the clamping ring one and the clamping ring two on the clamping plate can be driven to make a clamping and folding action by the push device. During this period, the hot gas outlet on the clamping ring two is used to preheat and shrink the film, and then the clamping groove of the clamping ring one is used for further heat shrinkage. The step-by-step heat shrinkage can ensure the heat shrinkage wrapping effect and improve the product quality. When folding, the clamping groove of the clamping ring one can be clamped on the outer circle of the cutting knife, and the wrapping is pressed flat and wrapped on the outer circle of the cutting knife.

[0030] The push device can adopt a linear output type power mechanism such as an oil cylinder, an air cylinder, etc. to drive the push plate and the components on the push plate to make linear reciprocating motion.

[0031] Specifically, the hot gas outlet intervals of the first clamping ring are arranged on the upper and lower side walls of the clamping groove, and the hot gas outlet intervals of the second clamping ring are arranged on the side wall of the second clamping ring.

[0032] In this embodiment, the hot gas outlet intervals of the first clamping ring are arranged on the upper and lower side walls of the clamping groove, which can make the hot gas act more uniformly on the key part where the cutting knife is attached to the film, ensuring that the film is tightly and uniformly heat-shrunk at the clamping groove, effectively avoiding the situation of insufficient or excessive heat shrinkage in the local area, and improving the quality of heat shrinkage packaging in the key area. The hot gas outlet intervals of the second clamping ring are arranged on the side wall of the second clamping ring, which helps to uniformly preheat the film from the side, so that the film is preliminarily shrunk before entering the clamping groove of the first clamping ring, making it easier to complete accurate and tight heat shrinkage wrapping in the clamping groove, and further ensuring the consistency and reliability of the overall heat shrinkage packaging effect.

[0033] Specifically, the first clamping ring and the second clamping ring are each provided with a gas passage 10 for connecting the hot gas outlet and the hot gas inlet.

[0034] In this embodiment, the first clamping ring and the second clamping ring are provided with a gas passage connected with the hot gas inlet and outlet, which ensures smooth circulation of hot gas in the clamping ring, so that hot gas can be stably and continuously delivered from the hot gas inlet to the hot gas outlet, providing a stable heat source for film heat shrinkage. In addition, it can also reduce the weight of the clamping ring.

[0035] Specifically, one side of the push plate is fixed with a sliding rail 11, and the fixed support plate is fixed with a sliding block 12, and the sliding rail and the sliding block are in sliding cooperation.

[0036] The sliding rail fixed on one side of the push plate and the sliding block on the fixed support plate are in sliding cooperation, which provides stable guidance and support for the movement of the push plate. This makes the push plate move along the accurate trajectory when the push device drives the push plate to move, thereby ensuring the accuracy and repeatability of the positions of the first clamping ring and the second clamping ring when clamping the cutting knife. This precise movement control is conducive to improving the working precision of the heat shrinkage packaging mechanism, ensuring that the clamping position of the cutting knife is consistent every time, thereby improving the overall quality and stability of heat shrinkage packaging.

[0037] Specifically, the first clamping ring and the second clamping ring are each fixed with a clamping ring cover 13, and the first clamping ring and the clamping ring cover, and the second clamping ring and the clamping ring cover are provided with heat preservation cotton 14.

[0038] In the embodiment, the clamping ring cover is fixed on the clamping ring one and the clamping ring two, and the heat preservation cotton is arranged between the clamping ring and the clamping ring cover, so that the heat loss of hot gas can be effectively reduced, and the utilization rate of hot gas is improved. On the one hand, the heat preservation cotton can better maintain the heat in the clamping ring in the heat shrink packaging area, so that the film can be heat shrunk in a relatively stable high temperature environment, which helps to improve the heat shrink effect. On the other hand, reducing heat loss can also help to save energy and reduce energy consumption cost in the heat shrink packaging process, while reducing the impact on the surrounding environment temperature, improving the comfort and safety of the working environment.

[0039] Specifically, a plurality of through holes 15 are arranged on the clamping ring cover in intervals.

[0040] In the embodiment, the clamping ring cover is fixed on the clamping ring one and the clamping ring two, and the heat preservation cotton is arranged between the clamping ring and the clamping ring cover, so that the heat loss of hot gas can be effectively reduced, and the utilization rate of hot gas is improved. On the one hand, the heat preservation cotton can better maintain the heat in the clamping ring in the heat shrink packaging area, so that the film can be heat shrunk in a relatively stable high temperature environment, which helps to improve the heat shrink effect. On the other hand, reducing heat loss can also help to save energy and reduce energy consumption cost in the heat shrink packaging process, while reducing the impact on the surrounding environment temperature, improving the comfort and safety of the working environment.

[0041] Specifically, the hot gas outlet of the clamping ring one is an arc strip structure, and the hot gas outlet of the clamping ring two is a circular structure.

[0042] The hot gas outlet of the clamping ring one is designed as an arc strip structure, which can better fit the circular profile of the cutting knife, so that the hot gas is uniformly distributed along the outer circle of the cutting knife, ensuring that the film is evenly heated when it is heat shrunk around the outer edge of the cutting knife in the clamping groove, effectively avoiding the situation that local heat shrink is inconsistent, and improving the quality and aesthetics of heat shrink packaging in this area. The hot gas outlet of the clamping ring two is a circular structure, which is conducive to providing concentrated heat during the preheating stage of the film, so that the film can be quickly and uniformly preheated and shrunk, preparing for the subsequent precise heat shrink in the clamping groove of the clamping ring one. The different designs of the two complement each other, optimizing the entire heat shrink packaging process.

[0043] Specifically, the clamping ring one and the clamping ring two are both semi-circular ring structures.

[0044] The clamping ring one and the clamping ring two are both semi-circular ring structures, which are compatible with the shape of the outer circle of the disc-type cutting knife, and can provide a good ring-type clamping effect when clamping the cutting knife, ensuring the stability of the cutting knife position during the heat shrink packaging process.

[0045] Skilled persons should know that although the utility model has been described according to the above specific implementation mode, the utility model idea is not limited to this utility model, and any modification using the utility model idea will be included in the patent protection range.
