Description

Technical Field

[0001] The utility model belongs to the technical field of cutters, and in particular relates to a cooling device for a cutter base. Background Art

[0002] The cutting blades used in bag-making machines utilize a shearing mechanism. During high-speed shearing, the upper and lower blade edges are subject not only to vertical cutting forces but also to friction from springs in front and behind. The upper blade is the moving blade, while the lower blade is the stationary blade. During the cutting process, friction heats the blade edges, reaching temperatures exceeding 100°C. These high temperatures can lead to two problems: 1. The blade edges soften, reducing their sharpness, affecting cutting performance, increasing wear, and shortening the blade's lifespan. 2. Plastic bag cuts can stick together. The softening point of plastic is over 110°C. When the blade edge temperature approaches this point, the plastic at the cut ends sticks together, making it difficult to open the bag, impacting product quality. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the utility model provides a cutter base cooling device which avoids the softening of the cutting edge, reduction of sharpness and softening of plastic, and adhesion caused by overheating of the cutter, thereby improving the production quality of plastic packaging and extending the service life of the cutter.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a cutter base cooling device, comprising a cutter base, wherein the cutter base is a square structure with corresponding openings at the front and rear, and the cutter base is fixed into an internal hollow square structure by the cooperation of a fixing hole and a fixing piece, and a cooling pipe is provided inside the cutter base, and the inlet and outlet of the cooling pipe pass through the side of the cutter base and extend to the outside of the cutter base.

[0005] Preferably, the cutter base is a cast aluminum part.

[0006] Preferably, the cooling pipe includes a straight pipe and a U-shaped pipe.

[0007] Preferably, the cooling pipe is a single-layer or multi-layer serpentine pipe.

[0015] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. Example

[0017] See attached Figure 1-3 As shown, a cutter base cooling device includes a cutter base 1, which is a square structure with corresponding openings at the front and back. The cutter base 1 is fixed into an internal hollow square structure through the cooperation of a fixing hole 2 and a fixing piece. A cooling pipe 3 is provided inside the cutter base 1, and the inlet 4 and outlet 5 of the cooling pipe 3 pass through the side of the cutter base 1 and extend to the outside of the cutter base 1.

[0018] Preferably, the cutter base 1 is a cast aluminum part.

[0019] Preferably, the cooling pipe 3 includes a straight pipe and a U-shaped pipe 6 .

[0020] Preferably, the cooling pipe 3 is a single-layer or multi-layer serpentine pipe 7 .

[0021] Preferably, the cooling pipes 3 are arranged on the same side or different sides.

[0022] Working principle: The solid cast iron of the cutter base is replaced with a hollow cast aluminum structure. The thermal conductivity of aluminum is better than that of cast iron. The internal reflux pipe is cooled by cooling water or other cooling liquids. The water is refrigerated cold water. The cooling water cools the cast aluminum. The lower cutter is installed on the cast aluminum to achieve the effect of cooling the lower cutter, avoiding the softening of the cutting edge caused by overheating of the cutter, the reduction of sharpness and the softening of plastic, which may cause adhesion. This improves the production quality of plastic packaging and extends the service life of the cutter.

[0023] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
