Description

Technical Field

[0001] The utility model relates to the technical field of paper cup processing, in particular to a feeding structure for paper cup processing. Background Art

[0002] Paper cups are a kind of paper container made by mechanically processing and gluing base paper made of chemical wood pulp. They have a cup-shaped appearance. Paper cups are safe, hygienic, lightweight and convenient. They can be used in public places, hotels and restaurants. They are disposable items. When processing paper cups, paper is needed. Therefore, a feeding device is needed in the process of processing paper cups to process the paper to be processed.

[0003] The existing feeding device has certain disadvantages when in use. When the existing feeding device is in use, after the paper is initially cut and processed, the cut paper is usually directly placed on a conveyor belt for transportation. However, since the paper is too thin, it is easy for the paper to fall from the conveyor belt during the transportation process, thereby making the paper dirty. The staff is required to clean up the fallen paper, which cannot meet people's needs.

[0004] For example, a feeding device for paper cup processing disclosed in Chinese patent CN219706213U puts paper into a feeding box through a feeding seat and a feeding mechanism. The limiting member can limit the paper, and the connecting member can limit the limiting member through a rotating seat, a limiting member, a connecting seat and an elastic limiting block. The rotating seat and the connecting seat can adjust the height on the feeding box through a moving block and a limiting rod, so that different quantities of paper can be fixed, thereby preventing the paper from falling, making it convenient for people to use. The whole device has a simple structure and is easy to operate, which increases the applicability of the feeding device.

[0005] However, the feeding device will fix the paper in the feeding box during transportation, so after the feeding box moves to the feeding position, the fixing structure in the feeding box needs to be opened to take out the paper, which is very cumbersome.

[0006] For this reason, we urgently need to provide a feeding structure for paper cup processing that does not require paper to be fixed. Utility Model Content

[0007] The purpose of the utility model is to provide a feeding structure for paper cup processing, so as to solve the problem that the feeding device proposed in the above-mentioned background technology will fix the paper in the feeding box during transportation, so that after the feeding box moves to the feeding position, it is necessary to open the fixing structure in the feeding box to take out the paper, which is very cumbersome.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding structure for paper cup processing, comprising a conveyor and a lower hopper, wherein the lower hopper is fixedly connected to the lower right end of the conveyor, and a feeding mechanism is connected to the outer end of the conveyor, wherein the feeding mechanism comprises a clamping unit and a limiting unit, wherein the clamping unit is arranged at the upper end of the conveyor, and the limiting unit is arranged at the front and rear ends of the conveyor.

[0009] The clamping unit includes a rectangular frame, a round rod, a pressure roller, a fixed plate, a bearing, a first threaded rod, a first handle and a movable plate. The rectangular frame is arranged above the conveyor, the round rod is connected to the inside of the rectangular frame, the pressure roller is fixedly connected to the outside of the round rod, the fixed plate is fixedly connected to the middle position above the front and rear sides of the conveyor, the bearing is fixedly connected to the inside of the fixed plate, the first threaded rod is fixedly connected to the inner side of the bearing, the first handle is fixedly connected to the upper end of the first threaded rod, and the movable plate is connected to the outer end of the first threaded rod.

[0010] A further improvement is that a first threaded hole is provided in the middle of the movable plate, the outer side of the movable plate is fixedly connected to the middle of the front and rear sides of the rectangular frame, and the outer side of the first threaded rod is threadedly connected to the inner side of the first threaded hole. Thus, when the first handle is turned to drive the first threaded rod in the threaded hole to rotate, the movable plate can be moved along the outer side of the first threaded rod, thereby driving the rectangular frame to move together.

[0011] A further improvement is that the front and rear ends of the rectangular frame are provided with rotating holes at equal distances, the front and rear ends of the round rod are rotatably connected to the inner side of the rotating holes, and the outer side of the pressure roller is rollingly connected to the upper side of the paper to be transported. Therefore, after the first handle is turned to drive the first threaded rod to rotate so that the rectangular frame moves, the lower end of the pressure roller is driven to move to the height of the upper side of the paper to be transported on the conveyor, so that when the paper is transported on the conveyor, the upper side of the paper will contact the lower side of the pressure roller, so that the round rod in the pressure roller rotates while the pressure roller rolls on the upper side of the paper, pressing the paper to the upper end of the conveyor, and after being transported to the right end of the conveyor and no longer pressed by the pressure roller, it will fall to the lower hopper to be collected.

[0012] A further improvement is that the limiting unit includes a connecting frame, a cylinder, a limiting plate, a sliding plate, a sliding rod, a second threaded rod and a second handle, the connecting frame is fixedly connected to the front and rear sides of the conveyor at equal distances, the cylinder is fixedly connected to the side of the connecting frame away from the conveyor, the limiting plate is fixedly connected to the output shaft end of the cylinder, the sliding plate is connected to the inside of the limiting plate, the sliding rod is fixedly connected to the front and rear sides of the sliding plate, the second threaded rod is connected to the middle position of the upper end of the inner part of the limiting plate, and the second handle is fixedly connected to the end of the second threaded rod away from the limiting plate.

[0013] A further improvement is that a groove is provided at one end of the limiting plate near the conveyor in the middle, and limiting grooves are provided at the front and rear ends of the limiting groove. The outer side of the sliding plate is slidably connected to the inner side of the groove, and the outer side of the sliding rod is slidably connected to the inner side of the limiting groove. Therefore, when the sliding plate slides inside the groove, the sliding rod will slide along the inner side of the limiting groove, thereby limiting the movement of the sliding plate.

[0014] A further improvement is that a second threaded hole is provided in the middle of the upper end of the limit plate, the outer side of the second threaded rod is threadedly connected to the inner side of the second threaded hole, and the end of the second threaded rod away from the second handle abuts against the outer side of the sliding plate. Thus, according to the distance between the rectangular frame and the upper end of the conveyor, after the sliding plate is slid to the corresponding position in the limit plate so that the overall height of the limit plate and the sliding plate is appropriate, the second handle is rotated to drive the second threaded rod to rotate in the second threaded hole and move at the same time, until the end of the second threaded rod away from the second handle moves to contact the outer side of the sliding plate, the sliding plate can be fixed to the groove, so that the overall height of the limit plate and the sliding plate can be changed with the spacing between the conveyor and the pressure roller.

[0015] A further improvement is that an anti-skid pad is fixedly connected to the outer side of the pressure roller, so that when the paper is transported on the conveyor and the pressure roller rolls on the paper, the rubber pad on the outer side of the pressure roller contacts the upper side of the paper, which can prevent the upper side of the paper and the pressure roller from sliding relative to each other and failing to firmly press the paper.

[0016] In summary, the present application discloses a feeding structure for processing paper cups.

[0017] The technical solution drives the first threaded rod to rotate by rotating the first handle to move the rectangular frame, and then drives the lower end of the pressure roller to move to the upper height of the paper to be conveyed on the conveyor. When the paper is transported on the conveyor, the upper side of the paper will contact the lower side of the pressure roller, so that the round rod in the pressure roller rotates while the pressure roller rolls on the upper side of the paper, pressing the paper to the upper end of the conveyor, and after being transported to the right end of the conveyor and no longer pressed by the pressure roller, it will fall onto the lower hopper and be collected.

[0018] Furthermore, by starting the cylinder and moving its output shaft to drive the limit plate to move to the front and rear sides of the paper being transported on the conveyor, the paper being transported on the conveyor can be limited so that the paper will not deviate during movement and fall from the conveyor.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] A feeding structure for paper cup processing includes a conveyor 1 and a lower hopper 2. The lower hopper 2 is fixedly connected to the lower right end of the conveyor 1. The outer end of the conveyor 1 is connected to a feeding mechanism. The feeding mechanism includes a clamping unit and a limiting unit. The clamping unit is arranged at the upper end of the conveyor 1, and the limiting unit is arranged at the front and rear ends of the conveyor 1.

[0029] The clamping unit includes a rectangular frame 301, a round rod 302, a pressure roller 303, a fixed plate 304, a bearing 305, a first threaded rod 306, a first handle 307 and a movable plate 308. The rectangular frame 301 is arranged above the conveyor 1, the round rod 302 is connected to the inside of the rectangular frame 301, the pressure roller 303 is fixedly connected to the outside of the round rod 302, the fixed plate 304 is fixedly connected to the middle position above the front and rear sides of the conveyor 1, the bearing 305 is fixedly connected to the inside of the fixed plate 304, the first threaded rod 306 is fixedly connected to the inner side of the bearing 305, the first handle 307 is fixedly connected to the upper end of the first threaded rod 306, and the movable plate 308 is connected to the outer end of the first threaded rod 306.

[0030] A first threaded hole is provided in the middle of the movable plate 308, the outer side of the movable plate 308 is fixedly connected to the middle of the front and rear sides of the rectangular frame 301, and the outer side of the first threaded rod 306 is threadedly connected to the inner side of the first threaded hole. Thus, when the first handle 307 is rotated to drive the first threaded rod 306 in the threaded hole to rotate, the movable plate 308 can be moved along the outer side of the first threaded rod 306, thereby driving the rectangular frame 301 to move together.

[0031] Rotation holes are provided at equal distances at the front and rear ends of the rectangular frame 301, and the outer sides of the front and rear ends of the round rod 302 are rotationally connected to the inner sides of the rotation holes, and the outer side of the pressure roller 303 is rollingly connected to the upper side of the paper to be transported. Therefore, after the first handle 307 is rotated to drive the first threaded rod 306 to rotate so that the rectangular frame 301 moves, the lower end of the pressure roller 303 is driven to move to the height of the upper side of the paper to be transported on the conveyor 1, so that when the paper on the conveyor 1 is transported, the upper side of the paper will contact the lower side of the pressure roller 303, so that the round rod 302 in the pressure roller 303 is rotating while rotating, and the pressure roller 303 is located on the upper side of the paper and rolls, pressing the paper to the upper end of the conveyor 1, and after being transported to the right end of the conveyor 1 and no longer pressed by the pressure roller 303, it will fall to the lower hopper 2 to be collected.

[0032] Embodiment 2:

[0033] On the basis of Example 1: the limiting unit includes a connecting frame 401, a cylinder 402, a limiting plate 403, a sliding plate 404, a sliding rod 405, a second threaded rod 406 and a second handle 407, the connecting frame 401 is fixedly connected to the front and rear sides of the conveyor 1 at equal distances, the cylinder 402 is fixedly connected to the side of the connecting frame 401 away from the conveyor 1, the limiting plate 403 is fixedly connected to the output shaft end of the cylinder 402, the sliding plate 404 is connected to the inside of the limiting plate 403, the sliding rod 405 is fixedly connected to the front and rear sides of the sliding plate 404, a groove is provided at the middle position of the limiting plate 403 near the end of the conveyor 1, and a limiting groove is provided at the front and rear ends of the groove inside the limiting plate 403, the outer side of the sliding plate 404 is slidably connected to the inner side of the groove, and the outer side of the sliding rod 405 is slidably connected to the inner side of the limiting groove. Therefore, when the sliding plate 404 slides on the inner side of the groove, the sliding rod 405 will slide along the inner side of the limiting groove, thereby limiting the movement of the sliding plate 404.

[0034] The second threaded rod 406 is connected to the middle position of the upper end of the limiting plate 403, and the second handle 407 is fixedly connected to the end of the second threaded rod 406 away from the limiting plate 403. A second threaded hole is provided in the middle position of the upper end of the limiting plate 403, the outer side of the second threaded rod 406 is threadedly connected to the inner side of the second threaded hole, and the end of the second threaded rod 406 away from the second handle 407 abuts against the outer side of the sliding plate 404. Therefore, according to the distance between the rectangular frame 301 and the upper end of the conveyor 1, the sliding plate 404 is slid to the corresponding position in the limit plate 403 so that the overall height of the limit plate 403 and the sliding plate 404 is appropriate, and then the second handle 407 is rotated to drive the second threaded rod 406 to rotate in the second threaded hole and move at the same time until the end of the second threaded rod 406 moves away from the second handle 407 to contact the outside of the sliding plate 404, and then the sliding plate 404 can be fixed to the groove, so that the overall height of the limit plate 403 and the sliding plate 404 can change with the distance between the conveyor 1 and the pressure roller 303.

[0035] Embodiment three:

[0036] On the basis of the first embodiment: an anti-skid pad is fixedly connected to the outer side of the pressure roller 303. Therefore, when the paper is transported on the conveyor 1 and the pressure roller 303 rolls on the paper, the rubber pad on the outer side of the pressure roller 303 contacts the upper side of the paper, which can prevent the upper side of the paper and the pressure roller 303 from sliding relative to each other and failing to firmly press the paper.

[0037] Working principle: When the paper is to be transported, first turn the first handle 307 to drive the first threaded rod 306 to rotate so that the rectangular frame 301 moves, and then drive the lower end of the pressure roller 303 to move to the upper height of the paper to be transported on the conveyor 1, then start the cylinder 402 and its output shaft moves to drive the limit plate 403 to move, until the distance between the limit plates 403 at the front and rear ends is the width of the paper to be transported, then start the conveyor 1, place the paper to be transported on the conveyor 1, drive the paper to move to the right along the limit plates 403 and the lower end of the pressure roller 303, until it moves to the right end of the conveyor 1 and is no longer pressed by the pressure roller 303, and then falls to the lower hopper 2 to be collected.
