Description

Technical Field

[0001] This utility model relates to the field of paper cup rim rolling processing, and in particular to an automatic correction device for a paper cup rim rolling forming machine. Background Technology

[0002] In the paper cup production process, edge rolling is a key process to ensure the structural stability and safety of the paper cup. After the paper cup is rolled and formed in the early stage, it needs to be conveyed to the edge rolling machine for edge rolling treatment. The positional accuracy of the paper cup during the conveying process directly affects the flatness and consistency of the edge rolling.

[0003] To ensure the quality of subsequent processing, an automatic paper cup alignment device is required. However, traditional alignment devices have some shortcomings.

[0004] Common automatic correction devices typically use guide plates on both sides to guide and correct the paper cups. However, the positions of traditional guide plates are often fixed, making them unsuitable for paper cups of different diameters. When production specifications are changed, manual adjustment is required. The adjustment process is cumbersome, takes a long time, and results in low efficiency. Furthermore, the adjustment process requires a lot of labor.

[0005] To address this issue, an automatic correction device for a paper cup roll forming machine is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an automatic correction device for a paper cup roll forming machine, which aims to improve the problems of fixed guide plate position, inability to adapt to paper cups of different diameters, and manual adjustment required for specification switching in the existing technology, which leads to wasted time and labor.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 2This utility model provides an embodiment of an automatic correction device for a paper cup roll forming machine. The correction device is installed in the process before the roll forming machine (not shown in the figure). It includes a conveyor 1 for conveying paper cups rolled into a cylindrical shape. When the paper cup is placed on the conveyor 1, the side with the smaller diameter is placed forward. A support plate 2 is fixedly connected to the inner surface of the conveyor 1. A positioning component 300 is provided on the upper part of the conveyor 1 to limit the left and right directions of the paper cup. The positioning component 300 can be adapted to paper cups of different diameters and guides the paper cup to avoid the problem of misalignment of the roll opening caused by the offset of the paper cup during conveying.

[0034] Reference Figure 1 , Figure 2 , Figure 4 The positioning component 300 includes a guide plate 308 for guiding the paper cup. A slide rod 307 is fixedly connected to the left surface of the guide plate 308. The guide plate 308 and the slide rod 307 move synchronously. The slide rod 307 passes through and is slidably connected to the left surface of the conveyor 1. A motor 301 for driving the screw 302 is provided on the lower surface of the support plate 2. The output shaft of the motor 301 is fixedly connected to the screw 302 for driving the positioning plate 303 to move. Both the motor 301 and the screw 302 are prior art and can be implemented by those skilled in the art. As they are prior art, they will not be described in detail in this case. The positioning plate 303 is threadedly connected to the outer wall of the screw 302. 2. When rotating, it will drive the positioning plate 303 to move longitudinally, and the thread helix angle of the thread groove on the outer wall of the screw 302 is less than ten degrees. When the screw 302 stops rotating, the position of the positioning plate 303 will be locked. The lower surface of the conveyor 1 is fixedly connected to the positioning rod 309 that provides guidance for the positioning plate 303. The left end of the upper surface of the positioning plate 303 is fixedly connected to the hinge seat 1 304. The inner surface of the hinge seat 1 304 is hinged to one end of the connecting rod 305. The other end of the connecting rod 305 is hinged to the hinge seat 2 306. The upper part of the guide plate 308 is provided with a separating component 400 for separating paper cups. The separating component 400 can prevent adjacent paper cups from being too close together, which would affect the subsequent rolling quality.

[0035] Reference Figure 1 , Figure 2 , Figure 4The screw 302 passes through and is rotatably connected to the inner surface of the support plate 2, and the positioning rod 309 passes through and is slidably connected to the inner surface of the positioning plate 303. This allows the positioning plate 303 to move only longitudinally. The second hinge seat 306 is fixedly connected to the left end of the lower surface of the slide rod 307. The first hinge seat 304, the connecting rod 305, the second hinge seat 306, the slide rod 307 and the guide plate 308 are all provided in two sets, which are symmetrically distributed on the left and right sides of the center line of the conveyor 1. When the positioning plate 303 moves longitudinally, the guide plates 308 on both sides will move closer or open synchronously to accommodate paper cups of different diameters. The rear section of the guide plate 308 is set as an outwardly inclined section, and the middle and front sections are smooth sections.

[0036] Reference Figure 1 - Figure 3 The separator assembly 400 includes a support base 401, which is fixedly connected to the upper surface of the guide plate 308 located on the left. A second motor 402 for driving the rotating shaft 403 is disposed on the front surface of the support base 401. The second motor 402 is prior art and can be implemented by those skilled in the art; therefore, it will not be described in detail in this case. The output shaft of the second motor 402 is fixedly connected to the rotating shaft 403, and a guide cylinder 404 is fixedly connected to the rear surface of the rotating shaft 403. The rotating shaft 403 and the guide cylinder 404 move synchronously. A guide groove 405 is formed on the outer wall of the guide cylinder 404. A slider 406 is slidably connected to the inner wall of guide plate 304. The slider 406 moves along the trajectory of guide groove 405. A sleeve 407 is fixedly connected to the upper surface of slider 406. The inner wall of sleeve 407 fits against the outer wall of guide cylinder 404. A connecting block 408 is fixedly connected to the right surface of sleeve 407. A fixing plate 409 is fixedly connected to the right surface of connecting block 408. The fixing plate 409 is thin and will not cause obstruction. When the fixing plate 409 is at the rear end, its rear surface will not protrude from the rear end of the smooth section of guide plate 308 and will not cause obstruction. A dividing block 410 for separating paper cups is fixedly connected to the right surface of fixing plate 409.

[0037] Reference Figure 1 - Figure 3The rotating shaft 403 is rotatably connected to the inner surface of the support base 401. The centers of the rotating shaft 403, guide cylinder 404, and sleeve 407 are on the same horizontal line and can rotate synchronously. The guide groove 405 is wavy with closed ends. When the guide groove 405 rotates, it will squeeze the slider 406, which will drive the sleeve 407 to move back and forth. The fixed plate 409 is slidably connected to the right surface of the guide plate 308 on the left. The rear surface of the separator block 410 is set as an inclined surface that gradually slopes backward from right to left. When the separator block 410 moves backward, it will move along the inclined surface of the paper cup. The inclined surface of the separator block 410 and the paper cup can provide guidance, and the paper cup will deform. When the separator block 410 moves to the rear end of the paper cup, the paper cup will recover due to its own elasticity. The backward movement of the separator block 410 will push the paper cup backward. The forward and backward movement speed of the separator block 410 is greater than the conveying speed of the conveyor 1.

[0038] Working principle: When it is necessary to adapt to paper cups of different diameters, start motor 301. Its output shaft drives screw 302 to rotate, which in turn drives positioning plate 303 to move longitudinally. When positioning plate 303 moves, it drives connecting rod 305 to move through hinge seat 304. Hinge seat 306 at the other end of connecting rod 305 pushes slide rod 307 to slide laterally, so that guide plates 308 on both sides move closer or open at the same time to form a guide channel that matches the diameter of paper cup. The inclined structure of the rear section of guide plate 308 guides the paper cup into the channel, and the smooth section in the middle section ensures that the paper cup stays centered during the conveying process and avoids left and right deviation, thus ensuring that the left and right position of the paper cup is accurate when it moves to the roll mouth area.

[0039] When in use, the motor 402 can be started to drive the rotating shaft 403 to rotate, which will drive the guide cylinder 404 to rotate synchronously. The wave-shaped guide groove 405 on the outer wall of the guide cylinder 404 will rotate synchronously with the guide cylinder 404 and will squeeze the slider 406. Since the fixed plate 409 and the guide plate 308 are slidably connected, the sleeve 407, the connecting block 408 and the fixed plate 409 will move back and forth.

[0040] The separator block 410 at the right end of the fixed plate 409 moves back and forth accordingly. When its inclined rear surface moves backward, it will move along the side wall of the paper cup to the rear end of the paper cup. During this process, the paper cup will be squeezed and deformed. When the separator block 410 moves to the rear side of the paper cup, the paper cup will recover under its own action. When the separator block 410 moves forward, it will push the single paper cup forward. Since the moving speed of the separator block 410 is greater than the conveying speed of the conveyor 1, it can effectively avoid the paper cups being too close together, thereby ensuring that the distance between the front and rear paper cups is appropriate when the paper cups move to the roll-up area.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
