Description

Technical Field

[0001] This utility model belongs to the field of paper cup processing technology, specifically relating to the knurling device of paper cup processing equipment. Background Technology

[0002] In the paper cup manufacturing industry, knurling is of great significance for improving the aesthetics of paper cups, enhancing the grip, and improving the overall quality of paper cups. As consumers' requirements for the appearance and user experience of paper cups continue to increase, the quality and effect of paper cup knurling are receiving more and more attention.

[0003] When performing knurling on paper cups, the adjustment of the downward pressure on both sides of the knurling is not flexible enough. Traditional adjustment methods often rely on relatively simple mechanical structures, such as adjusting the pressure through fixed nuts and screws. In actual operation, this method requires a lot of time to tighten the nuts and is difficult to precisely control the downward pressure on both sides of the knurling. When knurling paper cups of different materials and thicknesses, the inability to adjust the downward pressure on both sides of the knurling in a timely and flexible manner leads to difficulties in adjusting the knurling force. This not only reduces production efficiency but may also result in uneven knurling force, with some areas being knurled too deep or too shallow, seriously affecting the quality of the finished paper cups, increasing the defect rate, and causing unnecessary economic losses to the company.

[0004] Therefore, in response to the problem that the existing paper cup knurling equipment has difficulty in adjusting the knurling force due to the inflexible adjustment of the downward pressure on both sides of the knurling, a knurling device for the paper cup processing equipment can be designed. Utility Model Content

[0005] To overcome the problem that existing paper cup knurling equipment has difficulty adjusting the knurling force due to the inflexible adjustment of the downward pressure on both sides of the knurling.

[0006] The technical solution of this utility model is as follows: a knurling device for paper cup processing equipment, including a fixed roller assembly and a downward knurling assembly; the lower end of the fixed roller assembly is provided with the downward knurling assembly; the fixed roller assembly includes a fixed roller shaft, a fixed roller shaft support, a drive motor, and a reduction gearbox; the downward knurling assembly includes a conical embossing roller shaft, a first lifting bearing, a second lifting bearing, a first lifting slide rail, a second lifting slide rail, a first lifting cylinder, and a second lifting cylinder.

[0007] Preferably, the precise force adjustment function of the downward knurling process is achieved by using the first lifting bearing and the second lifting bearing that can be raised and lowered at both ends of the conical embossing roller shaft. This effectively avoids the problem of inflexible and uneven force adjustment at both ends of the knurling process, and solves the problem of difficulty in adjusting the force of paper cup knurling processing caused by the inflexible adjustment of the downward pressure on both sides of the knurling in existing paper cup knurling processing equipment.

[0008] Preferably, a second lifting bearing and a first lifting bearing are respectively provided at both ends of the fixed roller shaft, and the second lifting bearing and the first lifting bearing are rotatably connected to the ball bearing of the tapered embossing roller shaft; a first lifting slide rail is provided at the rear end of the first lifting bearing, and the first lifting bearing is connected to the first lifting slide rail in a lifting and lowering manner; a second lifting slide rail is provided on the outer side of the second lifting bearing, and the second lifting bearing is connected to the second lifting bearing in a lifting and lowering manner along the second lifting bearing rail.

[0009] Preferably, a second lifting cylinder is provided at the upper end of the second lifting bearing, and the telescopic rod of the second lifting cylinder is rotatably connected to the outer shell of the second lifting bearing.

[0010] Preferably, a first lifting cylinder is provided at the upper end of the first lifting bearing, and the telescopic rod of the first lifting cylinder is fixedly connected to the first lifting bearing.

[0011] Preferably, a fixed roller shaft is provided at the lower end of the conical embossing roller shaft; both ends of the fixed roller shaft are provided with fixed roller shaft supports, and the fixed roller shaft supports and the fixed roller shaft are rotatably connected by bearings.

[0013] Preferably, the fixed roller shaft and the conical embossing roller shaft are connected by frictional transmission.

[0014] The beneficial effects of this utility model are:

[0015] 1. Existing paper cup knurling equipment suffers from difficulties in adjusting the knurling force due to inflexible adjustment of the downward pressure on both sides of the knurling process. This problem is addressed by using a first and second lifting bearing at both ends of a conical embossing roller shaft to achieve precise adjustment of the downward knurling force. This effectively avoids the problem of inflexible and uneven force adjustment at both ends of the knurling process. Furthermore, the knurling process between the conical embossing roller shaft and the fixed roller shaft increases the rotation speed of the embossing end, thereby improving processing efficiency. This solves the problem of difficulty in adjusting the knurling force in existing paper cup knurling equipment due to inflexible adjustment of the downward pressure on both sides of the knurling process.

[0016] 2. By using the first lifting cylinder and the second lifting cylinder, each of the first lifting cylinder and the second lifting cylinder controls the downward pressure at both ends of the conical embossing roller shaft, thereby improving the fine control function of the downward pressure.
