Description

Technical Field

[0001] This utility model relates to the field of spiral cutter technology, specifically an adjustable double-tooth spiral cutter. Background Technology

[0002] Packaging machinery refers to machinery that can complete all or part of the packaging process for products and commodities. The packaging process includes major processes such as filling, wrapping, and sealing, as well as related pre- and post-processes such as cleaning, stacking, and unpacking. In addition, packaging also includes processes such as measurement or stamping on the packaged items. Using machinery to package products can improve productivity, reduce labor intensity, and meet the needs of large-scale production. Cutting tools are important tools in the packaging machinery industry. However, the spiral cutters currently used in the high-end cardboard industry mostly adopt a single-tooth structure, which results in excessive cutting force and a short service life of the spiral cutter.

[0003] In response, Chinese patent application number CN202120082728.9 discloses a left-right adjustable double-tooth spiral cutter, including a spiral cutter with a blade on one side, comprising a first blade and a second blade arranged side by side. The spiral cutter has multiple sets of mounting grooves on its side for fixed connection with a power device, and a locking hole at the center of each groove. Both the first and second blades have a first inclined surface and a second inclined surface, and their cross-sectional shapes are both "V"-shaped. The mounting grooves are arranged along the length of the spiral cutter, and the depth of the locking hole is greater than the depth of the mounting grooves. The mounting grooves and locking holes facilitate the installation of the spiral cutter on an existing power device. The power device then drives the spiral cutter to cut the object. The use of both the first and second blades enables double-tooth double-cutting, reducing friction. The left-right adjustment reduces cutting force, resulting in a longer service life for the spiral cutter.

[0004] This double-tooth spiral cutter has a mounting groove along its length, which can be adjusted left and right to reduce cutting force. However, the blade and the spiral cutter are an integral structure. After long-term use, the blade will wear down or even chip. Continued use will result in discontinuous cut surfaces, affecting the cutting experience. If replacement is required, the spiral cutter must be replaced as well, which is costly and detrimental to the company's production development.

[0005] Therefore, in order to solve the above problems, an adjustable double-tooth spiral cutter is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable double-tooth spiral cutter to solve the problem mentioned in the background art. In the prior art, the double-tooth spiral cutter can reduce cutting force by adjusting left and right by setting a mounting groove along the length of the spiral cutter. However, the blade and the spiral cutter are an integral structure. After long-term use, the blade will wear down or even chip. Continued use will result in discontinuous cut surfaces, affecting the cutting experience. If replacement is required, the spiral cutter must be replaced as well, which is costly and detrimental to the production development of enterprises.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable double-tooth spiral cutter, comprising: a cutter plate; The top surface of the blade is provided with an installation groove, and the front and rear walls of the blade are provided with a first large slot and a first small slot. The blade plate is equipped with a blade structure, which includes a mounting plate. The mounting plate is movably installed inside the mounting groove. The upper end of the mounting plate is integrally formed with a blade body. The front and rear walls of the blade body are provided with a second large slot and a second small slot. A large retaining sleeve is inserted into the inner side of the second large slot, and a small retaining sleeve is integrally formed at the rear end of the large retaining sleeve.

[0008] Preferably, the length of the blade is adapted to the length of the mounting plate.

[0009] Preferably, the first large card slot and the first small card slot are aligned front to back, the second large card slot and the second small card slot are aligned front to back, and the first large card slot, the second large card slot, the second small card slot and the first small card slot are aligned front to back.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting the blade plate and the blade body to be detachable, the blade body can be replaced separately after the blade body is worn by removing the mounting plate from the inside of the mounting groove, so that the blade plate can be reused, reducing replacement costs, improving the economy of the device, and ensuring the user experience of the device.

[0014] This utility model, by incorporating a blade structure, allows the mounting plate to be installed downwards inside the mounting groove during installation. This aligns the first large and first small slots on the blade with the second large and second small slots on the mounting plate, with the interiors of these slots interconnected. Inserting a small retaining sleeve into the first and second small slots allows the large retaining sleeve to be secured within them, thus fixing the mounting plate in place within the mounting groove. Bolts are then inserted into the large and small retaining sleeves, and rotating them secures the blade to the existing power unit. The power unit then drives the blade to cut the object. The blade's design enables double-tooth double-cutting, reducing friction. Adjusting the position of the bolts inside the large and small retaining sleeves allows for adjustment of the blade's position on the device, reducing cutting force and extending its service life.
