While these complex structures effectively accommodate different paper thicknesses, they also make maintenance and troubleshooting extremely difficult. Operators require advanced professional skills, and the maintenance process is cumbersome and inefficient.

[0004] Therefore, a paper leveling mechanism for a cup-making machine is proposed to solve the problems of complex structure and inconvenient maintenance mentioned above. Utility Model Content

[0011] Preferably, the cup-connecting machine body is provided with a correction part, and the correction part is connected to the first leveling roller. The correction part includes a drive module, a threaded rod, and two symmetrically arranged correction plates. The threaded rod is connected to the output shaft of the drive module, and the correction plates are threadedly connected to the outside of the threaded rod. The correction plates move relative to or away from each other on the first leveling roller.

[0012] Preferably, the threaded rod and the first leveling roller are on the same vertical line, and the threaded rod is provided with two kinds of external threads in opposite directions.

[0013] Preferably, the correction plate has a through hole for the first leveling roller to pass through, and the through hole is in clearance fit with the first leveling roller.

[0018] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0019] (1) The paper leveling mechanism of the cup making machine is equipped with a leveling component. The paper conveying channel formed by the shaft and balance bar in the leveling component can adapt to paper of different thicknesses. The shaft and balance bar form a simple mechanical structure.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1:

[0034] Please see Figure 1-4 The paper leveling mechanism of a cup-making machine in this embodiment includes a leveling component 400 disposed at its inlet along the feeding direction of the cup-making machine body 100.

[0035] It should be noted that the cup-connecting machine 100 is a common device in the prior art, and the usage method and working principle of the cup-connecting machine 100 are well known to those skilled in the art of paper cup processing. They will not be described in detail in this application. The model of the cup-connecting machine 100 in this application is ECRA.

[0036] The leveling component 400 includes a balance bar 403 and a shaft 401 distributed vertically upwards and downwards. A paper conveying channel in the feeding direction is formed between the balance bar 403 and the shaft 401. The balance bar 403 performs vertical telescopic movement above the shaft 401. The two ends of the shaft 401 are provided with first baffles 200, and the first baffles 200 are provided on the cup-connecting machine body 100. The balance bar 403 is elastically connected to the first baffles 200.

[0037] In application, when the paper enters the paper conveying channel, the paper presses against the balance bar 403. At this time, the elastically connected balance bar 403 presses against the shaft 401 with elastic force, thereby smoothing out the uneven parts on the paper. In addition, the elastically connected balance bar 403 can adapt to paper of different thicknesses through elastic force, and can effectively press the paper against the shaft 401, thus realizing the smoothing of paper of different thicknesses through a simple mechanical structure.

[0038] It should be noted that the first leveling roller 402 is rotatably connected to the outer side of the shaft 401, and the second leveling roller 404 is rotatably connected to the outer side of the balance bar 403. The paper conveying channel is located between the first leveling roller 402 and the second leveling roller 404. The first leveling roller 402 and the second leveling roller 404 can rotate freely and move synchronously with the paper, which can reduce friction, prevent the paper from being scratched or torn, keep the paper flat during the conveying process and reduce wrinkles.

[0039] Furthermore, the first baffle 200 has a vertically opening 406 corresponding to the balance bar 403. The balance bar 403 has pressure blocks 405 fixed at both ends, and the pressure blocks 405 move vertically within the opening 406. A spring 407 is fixed between the pressure blocks 405 and the opening 406. A sliding member is provided on the pressure blocks 405. A sliding groove is vertically opened on the inner side wall of the opening 406, and the sliding member is slidably connected to the sliding groove.

[0040] In application, when the paper passes through the paper conveying channel formed by the balance bar 403 and the shaft 401, the first leveling roller 402 and the second leveling roller 404 rotate under the transmission of the paper. When the paper enters the paper conveying channel, the paper will squeeze the second leveling roller 404, causing the second leveling roller 404 to move in the vertical direction. At this time, the second leveling roller 404 also causes the pressure block 405 to move in the vertical direction within the connecting port 406. The moved pressure block 405 squeezes the spring 407, causing the spring 407 to deform. The elastic force generated when the spring 407 deforms causes the second leveling roller 404 to press the paper onto the first leveling roller 402. As the paper is squeezed by the first leveling roller 402 and the second leveling roller 404, under the synergistic action of the first leveling roller 402 and the second leveling roller 404, the unevenness and fluctuations on the paper can be effectively removed during the paper conveying process.

[0041] It is known that the sliding component is any one of a slider, a ball, and a graphite block. Preferably, the sliding component in this application is a ball. The ball has low friction and can withstand high loads, reducing the friction of the pressure block 405 during vertical movement. At the same time, the ball is easier to maintain.

[0042] Example 2:

[0043] The basic content is the same as in Example 1, except that:

[0044] Please see Figure 5In this embodiment, a correction part is provided on the cup-connecting machine body 100, and the correction part is connected to the first leveling roller 402. The correction part includes a drive module 408, a threaded rod 409, and two symmetrically arranged correction plates 410. The threaded rod 409 is connected to the output shaft of the drive module 408, and the threaded rod 409 is located between the opposite sides of the two first baffles 200. The correction plate 410 is threaded to the outside of the threaded rod 409, and the correction plate 410 moves relative to or away from each other on the first leveling roller 402.

[0045] When in use, the drive module 408 is started, and the output shaft of the drive module 408 begins to rotate, driving the threaded rod 409 to rotate. The two correction plates 410 move relative to each other or in opposite directions as the threaded rod 409 rotates. As the correction plates 410 move, they can limit the paper of different widths, ensuring that the paper enters the cup making machine 100 correctly, greatly reducing the number of defective cups during the production process and reducing the scrap rate.

[0046] It should be emphasized that during the process of the first leveling roller 402 and the second leveling roller 404 conveying the paper, the distance between the first leveling roller 402 and the second leveling roller 404 is greater than the distance between the second leveling roller 404 and the straightening plate 410. The paper will move between the two straightening plates 410, and the top surface height of the two straightening plates 410 is lower than the top surface height of the paper. Therefore, when the second leveling roller 404 acts on the paper through elastic force, it does not come into contact with the straightening plate 410 and will not affect the second leveling roller 404 pressing the paper.

[0047] It should be noted that the threaded rod 409 and the first leveling roller 402 are on the same vertical line. The threaded rod 409 is provided with two kinds of external threads in opposite directions. By using the two kinds of threads in opposite directions and the rotation of the threaded rod 409, the position of the correction plate 410 is precisely controlled, so as to achieve correction of paper with different widths.

[0048] The threaded rod 409 is a mechanical component with threads in different directions at both ends. It is typically used in applications requiring bidirectional movement or adjustment. Its design allows forces to be applied to both ends simultaneously when rotational force is applied, thereby enabling precise adjustment of the component or equipment.

[0049] Furthermore, the straightening plate 410 has a through hole for the first leveling roller 402 to pass through. The through hole and the first leveling roller 402 are in clearance fit. The clearance fit design helps to allow the first leveling roller 402 to move or adjust properly within the straightening plate 410, while avoiding mechanical damage or excessive wear caused by excessive tight fit.

[0050] The control unit controls the output shaft of the drive module 408 to rotate, causing the threaded rod 409 to rotate at a constant speed, ultimately achieving relative or opposite movement of the correction plate 410.

[0051] Example 3:

[0052] The basic content is the same as in Example 1, except that:

[0053] Please see Figure 6-8 In this embodiment, a heating chamber 411 is provided on the cup-connecting machine body 100 along the paper conveying direction. Several heating wires 412 are arranged at equal intervals inside the heating chamber 411. An air outlet 413 is connected to the top surface of the heating chamber 411. An air supply module 414 is provided on the cup-connecting machine body 100. An air outlet pipe 415 is provided at the output end of the air supply module 414 and the other end is connected to the heating chamber 411. A second baffle 300 is provided on the cup-connecting machine body 100 above the air outlet 413. Several air outlet holes are opened on the side of the air outlet 413 away from the heating chamber 411. The several air outlet holes are arranged in an array on the top surface of the air outlet 413.

[0054] When in use, the air supply module 414 is activated, and the air generated by the air supply module 414 enters the heating chamber 411 through the air outlet 415. The heating wire 412 in the heating chamber 411 heats the air in the heating chamber 411, and then the hot air enters the air outlet 413 and is finally sprayed out through multiple air outlets to preheat the paper material in transit. The second baffle 300 is used to limit the direction of the hot air so that the hot air can accurately heat the paper material in transit. At the same time, the array distribution can ensure that the airflow distribution of the air outlets is relatively uniform, thereby improving the preheating effect of the paper material. The above operation ensures the preheating effect of the paper material, reduces the internal stress of the paper material, prevents the paper cup from springing or deforming after forming, and reduces the scrap rate of the paper cup.

[0055] It should be noted that the heating wire 412 is any one of nickel-chromium alloy wire, iron-chromium-aluminum alloy wire, and tungsten wire. When current passes through the heating wire 412, it will be converted into heat, the temperature will rise, and the air in the heating chamber 411 will be heated.

[0056] It should be noted that the control unit controls the working state of the air supply module 414 to avoid excessive or insufficient air volume; the control unit and its working principle are well known to those skilled in the art, and will not be described in this embodiment.

[0057] In summary, the working principle of the paper leveling mechanism of this cup-making machine is as follows:

[0058] During the paper transport process of the cup-connecting machine body 100, the transported paper passes through the paper channel formed by the first leveling roller 402 and the second leveling roller 404. When the paper passes through, the first leveling roller 402 and the second leveling roller 404 begin to rotate, completing the transport of the paper. When thicker paper needs to be transported, the paper pushes up the second leveling roller 404, the balance bar 403, and the pressure block 405, at which time the spring 407 is compressed. When thinner paper needs to be transported, the second leveling roller 404, the balance bar 403, and the pressure block 405 move downward under the influence of gravity, at which time the spring 407 rebounds. At the same time, during the paper transport process, the drive module 408 is activated, and the output shaft of the drive module 408 begins to rotate, driving the threaded rod 409 to rotate. As the threaded rod 409 rotates, the two straightening plates 410 move relative to or away from each other. With the movement of the straightening plates 410, they can limit the paper of different widths, ensuring that the paper enters the cup making machine 100 correctly, greatly reducing the number of defective cups during the production process and reducing the scrap rate. At the same time, the air supply module 414 is activated. The air generated by the air supply module 414 enters the heating chamber 411 through the air outlet 415. The heating wire 412 in the heating chamber 411 heats the air in the heating chamber 411. Then the hot air enters the air outlet 413 and is finally sprayed out through multiple air outlets to preheat the paper in the transportation process, reduce the internal stress of the paper, prevent the paper cup from springing or deforming after forming, and reduce the scrap rate of the paper cup.
