Description

Technical Field

[0001] This utility model relates to the technical field of guide shaft fixing seats, and in particular to a knurled guide shaft fixing seat for a paper cup machine. Background Technology

[0002] The knurling guide shaft retainer is mainly used to fix the knurling guide shaft, playing a supporting, guiding, and fixing role during the operation of the paper cup machine. It ensures that the knurling guide shaft can operate stably and withstand the axial and radial loads from the knurling shaft, thereby ensuring the normal operation of the paper cup machine and the processing quality of the paper cups.

[0003] In the prior art, the structure of the knurled guide shaft retainer is as follows: Figure 3 The device includes a fixed base 1, a linear guide rail, a linear bearing 11 slidably mounted on the linear guide rail, and a fixing ring 12 that fixes the linear bearing 11 to the fixed base 1. Several balls 111 are slidably arranged on the inner wall of the linear bearing 11, and the balls 111 roll along the linear guide rail. Since two fixing rings 12 are needed to fix the linear bearing 11 to the fixed base 1, the structure is complex and inconvenient for assembly and fixation. Furthermore, the balls 111 need to roll continuously, requiring constant lubrication. Because there is a certain gap between the balls 111 and the linear guide rail, dust falling from the top can easily adhere to the lubricating oil through this gap. Over time, the accumulated dust and lubricating oil can mix to form sludge or solid impurities, which adhere to the surface of the balls 111 and the guide rail, hindering the normal rolling of the balls 111 and significantly increasing the sliding resistance. Increased sliding resistance not only reduces the motion accuracy and response speed of the equipment but may also cause overload of the drive motor, leading to malfunctions. To address the aforementioned issues, a knurled guide shaft fixing seat for paper cup machines is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a knurling guide shaft fixing seat for a paper cup machine. Through ingenious structural design, this knurling guide shaft fixing seat for a paper cup machine achieves a combination of stable installation and flexible adjustment. At the same time, it adds a dustproof structure to effectively prevent external dust and impurities from entering, keep the inside of the equipment clean, extend the service life of the equipment, and improve the reliability and maintainability of the equipment.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a knurled guide shaft fixing seat for a paper cup machine, including a fixed base, the fixed base having an installation cavity, a sliding inner sleeve being provided in the installation cavity, a limiting ring being provided on the outer side wall of the sliding inner sleeve, a limiting groove being provided in the installation cavity, the limiting ring being adapted to the shape of the limiting groove and being engaged in the limiting groove, the sliding inner sleeve having a deformation notch along its length direction, and a dustproof structure being provided at the upper end of the fixed base.

[0006] By adopting the above technical solution, the knurled guide shaft fixing seat of the paper cup machine achieves a stable and flexible structural design. The cooperation between the limiting ring and the limiting groove between the sliding inner sleeve and the fixed base not only ensures the stable installation of the sliding inner sleeve in the installation cavity, but also allows it to be finely adjusted or slid within a certain range, adapting to the usage requirements under different working conditions and enhancing the versatility and adaptability of the equipment. The design of the deformation notch allows the sliding inner sleeve to undergo a certain elastic deformation when subjected to external force, making it easy to install the sliding inner sleeve into the installation cavity. The result is simple, the manufacturing cost is low, and the installation is more convenient than the fixing ring in the prior art.

[0007] The dustproof structure is further configured such that: a positioning groove is provided at the top of the installation cavity, a dustproof ring is sealed in the positioning groove, and a number of bolts are used to fix the dustproof ring in the positioning groove, wherein the head of the bolt extends above the dustproof ring.

[0008] By adopting the above technical solution, including the positioning groove at the top of the mounting cavity, the dustproof ring installed in the positioning groove, and several bolts fixing the dustproof ring in the positioning groove, this design greatly improves the dustproof performance of the equipment. The dustproof ring, as the first line of defense, effectively blocks external dust and impurities from entering the mounting cavity, maintaining a clean internal environment and reducing equipment malfunctions and wear caused by dust accumulation. The bolt heads extend above the dustproof ring, ensuring not only a secure installation of the dustproof ring but also facilitating subsequent maintenance and replacement, thus improving the maintainability of the equipment.

[0009] A further configuration is provided: several of the aforementioned bolt ring dustproof rings are spaced apart circumferentially.

[0010] By adopting the above technical solution, several bolt ring dustproof rings are circumferentially spaced. This layout ensures that the dustproof rings are evenly supported and fixed in all directions, avoiding deformation or damage caused by excessive local stress, and enhancing the stability and reliability of the dustproof structure.

[0011] The dustproof ring is further configured such that: the dustproof ring includes a limiting part located in the positioning groove and a draining part extending from the upper end of the limiting part, and the draining part has a cross-section in the shape of an octagon.

[0012] By adopting the above technical solution, the dustproof ring includes a limiting part located within the positioning groove and a drainage part extending from the upper end of the limiting part. The drainage part's cross-section is designed in a figure-eight shape, cleverly utilizing fluid mechanics principles. When dust or impurities attempt to enter the installation cavity through the dustproof ring, the figure-eight-shaped drainage part can guide and block the flow, directing the dust and impurities to the outside of the dustproof ring, further improving the dustproof effect. Simultaneously, this design also reduces dust accumulation on the surface of the dustproof ring, keeping it clean and unobstructed, ensuring the long-term stable operation of the equipment.

[0013] The method is further configured such that: an oil passage is provided on the fixed base, the oil passage includes an inlet port and an outlet port, the outlet port is located in the positioning groove on the bottom side of the dustproof ring, and the inlet port is located on the outside of the fixed base.

[0014] By adopting the above technical solution, the oil passage can conveniently supply lubricating oil to components such as the mounting cavity and sliding inner sleeve without disassembling the fixed base, thus improving maintenance convenience. The outlet port is located in the positioning groove on the bottom side of the dustproof ring, which means that the lubricating oil can be directly delivered to the parts that need lubrication. At the same time, the dustproof ring sealing sleeve in the positioning groove can effectively prevent the lubricating oil from overflowing from the top of the positioning groove to the outside, effectively achieving the purpose of oil saving, ensuring the lubrication effect, extending the service life of the components, and saving more oil. The design of the oil passage takes into account the compactness of the overall structure. The inlet port is located on the outside of the fixed base, which is convenient for connecting to the external lubrication system, while the arrangement of the outlet port makes full use of the space below the dustproof ring, making the whole design both practical and space-saving.

The fixed base 2 has an installation cavity 3, and a sliding inner sleeve 21 is provided in the installation cavity 3. The sliding inner sleeve 21 is fitted onto a linear guide rail (the structure of the linear guide rail is not shown in the figure; the linear guide rail is existing technology, and the specific material of the linear guide rail is stainless steel). The sliding inner sleeve 21 is made of plastic (specifically, PTFE). A limit ring 212 is integrally provided on the outer wall of the sliding inner sleeve 21. A limit groove 31 is provided in the installation cavity 3. The shape of the limit ring 212 is adapted to the limit groove 31, and the limit ring 212 is engaged in the limit groove 31. A deformation notch 211 is provided along the length direction of the sliding inner sleeve 21. A dustproof structure is provided at the upper end of the fixed base 2. When the sliding inner sleeve 21 is squeezed by hand, it can undergo a certain elastic deformation, which facilitates the installation of the sliding inner sleeve 21 into the installation cavity 3.

[0021] The dustproof structure includes a positioning groove 32 at the top of the mounting cavity 3, a dustproof ring 22 sealed within the positioning groove 32, and several bolts 4 fixing the dustproof ring 22 within the positioning groove 32. The dustproof ring 22 is made of rubber, and the heads of the bolts 4 extend above the dustproof ring 22. The bolts 4 are spaced apart circumferentially around the dustproof ring 22. The dustproof ring 22 includes a limiting part 221 located within the positioning groove 32 and a drainage part 222 extending from the upper end of the limiting part 221. The drainage part 222 has a V-shaped cross-section. Dust adhering to the linear guide rail is drained away through the drainage part 222, effectively preventing external dust and impurities from entering the fixed base 2, maintaining the cleanliness of the equipment interior, extending the equipment's service life, and improving the equipment's reliability and maintainability.

[0022] An oil passage 23 is vertically provided on the fixed base 2. The oil passage 23 includes an inlet port 231 and an outlet port 232. The outlet port 232 is located in the positioning groove 32 on the bottom side of the dustproof ring 22, and the inlet port 231 is located on the bottom side of the fixed base 2. The inlet port 231 is connected to an oil system (the connection method between the oil system and the inlet port 231 is existing technology). This facilitates the supply of lubricating oil to components such as the mounting cavity 3 and the sliding inner sleeve 21, effectively preventing lubricating oil from overflowing from the top of the positioning groove 32 to the outside, effectively achieving the purpose of saving oil, ensuring the lubrication effect, extending the service life of the components, and saving more oil.
