Description

Technical Field

[0001] This utility model relates to the field of plastic cup production and processing, and more particularly to a plastic cup conveying mechanism. Background Technology

[0002] In the production of plastic cups, plastic film is typically thermoformed. After production, the product is transported by a conveyor belt to the rear, where it is wrapped in packaging film and then heat-sealed using a heat-sealing and cutting mechanism. In existing technology, to restrict the movement of the plastic cup along the middle of the conveyor belt and smoothly enter the packaging film, baffles are usually installed on both sides above the conveyor belt to limit the cup's movement. However, existing baffles are generally quite long and can only be adjusted inwards or outwards; that is, the baffle can only move towards or away from the middle of the conveyor belt. To accommodate different sizes of plastic cups, the baffles are typically quite tall, resulting in relatively high costs. Furthermore, the longer size of the baffles also increases the manufacturing difficulty, further raising costs. Moreover, replacement costs are high if damaged. Therefore, solving these technical problems is a direction that those skilled in the art need to address. Summary of the Invention

[0003] The purpose of this invention is to provide a plastic cup conveying mechanism. By using this structure, the convenience of adjusting the conveying mechanism is improved, and the stability of limiting the plastic cup is also guaranteed.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a plastic cup conveying mechanism, including a frame and a conveyor belt disposed on the frame, wherein a limiting component is respectively provided on the frame above the front and rear sides of the conveyor belt, the limiting component includes at least one limiting bracket, and a plurality of the limiting brackets are installed on the frame from left to right;

[0005] The limiting bracket includes a mounting frame, a positioning rod, and a limiting plate. There are two sets of mounting frames, which are installed on the outer side wall of the frame at intervals. The mounting frames can rotate relative to the frame. The positioning rod is arranged laterally and is located on the inner side of the two sets of mounting frames. The outer end of the positioning rod is provided with two adjusting rods, and the middle part of each adjusting rod is connected to the mounting frame.

[0006] The limiting plate is disposed on the inner side of the positioning rod, and a strip block is provided on the outer end face of the limiting plate. A transverse strip groove is provided on the outer end face of the strip block. The transverse strip groove is engaged with the positioning rod, and the limiting plate is disposed directly above the conveyor belt.

[0007] In the above technical solution, the two ends of the transverse strip groove are respectively connected to the left side wall and the right side wall of the strip block;

[0008] The top and bottom of the transverse strip groove are respectively provided with a flexible pad, and the bottom surface of the upper flexible pad and the top surface of the lower flexible pad respectively abut against the outer surfaces of the opposite sides of the positioning rod.

[0009] In the above technical solution, the bottom surface of the upper flexible pad has an upwardly recessed arc-shaped groove in the middle, and the top surface of the lower flexible pad has a downwardly recessed arc-shaped groove in the middle. The arc-shaped grooves of the upper and lower flexible pads respectively abut against the outer surfaces of the opposite sides of the positioning rod.

[0010] In the above technical solution, the right end of the positioning rod is provided with a guide rod, which is inclined outward from left to right and is located on the right side of the limiting plate.

[0011] In the above technical solution, the mounting bracket includes a mounting plate, a first limiting bolt, and a second limiting bolt. The lower inner wall of the mounting plate abuts against the outer wall of the frame. The mounting plate has a first through hole at its lower part and a second through hole at its upper part.

[0016] 1. In this utility model, limiting components are set on both sides of the frame. The limiting components adopt multiple sets of limiting brackets, that is, the segmented design of the limiting plate. The mounting bracket can rotate relative to the frame.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: See Figure 1-6 As shown, a plastic cup conveying mechanism includes a frame 1 and a conveyor belt 2 disposed on the frame 1. A limiting component 3 is respectively provided on the frame 1 above the front and rear sides of the conveyor belt 2. The limiting component 3 includes at least one limiting bracket 4, and multiple limiting brackets 4 are installed on the frame 1 from left to right.

[0028] The limiting bracket 4 includes a mounting frame 5, a positioning rod 6, and a limiting plate 7. There are two sets of mounting frames 5, which are installed on the outer side wall of the frame 1 at intervals. The mounting frames 5 can rotate relative to the frame 1. The positioning rod 6 is arranged laterally and is located on the inner side of the two sets of mounting frames 5. The outer end of the positioning rod 6 is provided with two adjusting rods 8, and the middle part of each adjusting rod 8 is connected to the mounting frame 5.

[0029] The limiting plate 7 is disposed inside the positioning rod 6. A strip block 9 is provided on the outer end face of the limiting plate 7. A transverse strip groove 10 is provided on the outer end face of the strip block 9. The transverse strip groove 10 is engaged with the positioning rod 6. The limiting plate 7 is disposed directly above the conveyor belt 2.

[0030] In this embodiment, the top surface of the conveyor belt transports products (plastic cups) from right to left. The product (plastic cup) is placed on the conveyor belt and positioned between the limiting components on both sides. The limiting components restrict the product. A packaging film can also be placed above the conveyor belt, allowing the product to enter the film before being fed into a heat-sealing and cutting mechanism for heat sealing. When limiting products of different sizes, the distance between the two sets of limiting components needs to be adjusted, as does the position of the limiting plate relative to the product. Therefore, adjusting the position of the adjusting rod relative to the mounting frame adjusts the distance between the positioning rod and the limiting plate relative to the center of the conveyor belt. When adjusting the height of the limiting plate, it ensures that the limiting plate is stably aligned with the center of the product. To limit product movement, simply rotate the mounting frame and adjust the vertical distance between the top of the mounting frame and the top surface of the conveyor belt, thereby adjusting the distance between the limiting plate and the top surface of the conveyor belt. Furthermore, in this embodiment, each limiting component includes multiple limiting brackets, i.e., a segmented design. During adjustment, the corresponding limiting brackets are adjusted sequentially to adjust the height and inner / outer positions of the limiting plate. If a set of limit brackets is damaged, the corresponding limit bracket can be replaced directly. Furthermore, since the limit plate is in contact with the product, it is prone to wear. Therefore, in this embodiment, a strip block is provided on the outer side of the limit plate, and a transverse strip groove is provided on the strip block. The limit plate quickly engages and limits itself via the transverse strip groove and the positioning rod, facilitating quick disassembly of the limit plate. Simultaneously, it allows adjustment of the angle between the limit plate and the top surface of the conveyor belt. In the prior art, the limit plate is perpendicular to the top surface of the conveyor belt. Since the plastic cup has a cylindrical structure, conventionally, only the edge of the product contacts the limit plate. Therefore, in this embodiment, the limit plate engages with the positioning rod via the transverse strip groove. The limit plate can also rotate relative to the positioning rod, adjusting the angle between the limit plate and the top surface of the conveyor belt. This allows the limit plates on the front and rear sides of the frame to form an upward-opening V-shaped structure, or a downward-opening V-shaped structure, or be perpendicular to the conveyor belt. The angle of the limit plate guides and limits the product conveying.

[0031] See Figure 5 , 6 As shown, the two ends of the transverse strip groove 10 are connected to the left and right sides of the strip block 9, respectively;

[0032] The top and bottom of the transverse strip groove 10 are respectively provided with a flexible pad 11. The bottom surface of the upper flexible pad 11 and the top surface of the lower flexible pad 11 abut against the opposite outer surfaces of the positioning rod 6. The flexible pads increase the friction with the positioning rod, so that after the limiting plate and the positioning rod are engaged, the limiting plate will not rotate relative to the positioning rod without being subjected to a certain external force, thus adjusting the angle between the limiting plate and the top surface of the conveyor belt. Moreover, when the product moves along the conveyor belt, if the product comes into contact with the limiting plate, it will exert a leftward pushing force on the limiting plate, and the friction of the flexible pads can also prevent the limiting plate from moving with it. Furthermore, in the initial state of the flexible pads, the distance between the upper and lower flexible pads is smaller than the diameter of the positioning rod. When engaged, the flexible pads are compressed, and the restoring force of the flexible pads presses against the positioning rod, thus limiting the limiting plate to the positioning rod.

[0033] See Figure 6 As shown, the upper flexible pad 11 has an upwardly recessed arc-shaped groove 12 in the center of its bottom surface, and the lower flexible pad 11 has a downwardly recessed arc-shaped groove 12 in the center of its top surface. The arc-shaped grooves of the upper and lower flexible pads respectively abut against the opposite outer surfaces of the positioning rod. The arc-shaped grooves and the outer surfaces of the positioning rod match to achieve the snap-fit ​​fixation of the limiting plate and the positioning rod.

[0034] See Figure 2-5 As shown, a guide rod 13 is provided at the right end of the positioning rod 6. The guide rod 13 is inclined outward from left to right and is located on the right side of the limiting plate 7. The guide rod guides the product when it enters the side limiting bracket, preventing jamming. Alternatively, only the right end of the rightmost positioning rod can be provided with a guide rod, while the right ends of the other positioning rods are not provided with guide rods. In this case, the right end of the left limiting plate is in contact with or close to the left side of the adjacent right limiting plate.

[0035] See Figure 4As shown, the mounting bracket 5 includes a mounting plate 14, a first limiting bolt 15, and a second limiting bolt 16. The lower inner wall of the mounting plate 14 abuts against the outer wall of the frame 1. The mounting plate 14 has a first through hole 17 at its lower part and a second through hole 18 at its upper part. The outer wall of the frame 1 has a first screw hole facing the first through hole 17. The first limiting bolt 15 passes through the first through hole 17 to limit the bottom of the mounting plate 14 to the outer wall of the frame 1.

[0036] The middle part of the adjusting rod 8 is inserted into the second through hole 18;

[0037] The top of the mounting plate 14 is provided with a second screw hole communicating with the second through hole 18. The second limiting bolt 16 is screwed to the second screw hole. The bottom of the second limiting bolt 16 abuts against the outer surface of the adjusting rod 8 and limits the middle part of the adjusting rod 8 within the second through hole 18.

[0038] The adjusting rod is inserted into the second through hole at the top of the mounting plate. When the second limit bolt is loosened, the adjusting rod can move back and forth relative to the second through hole to adjust the longitudinal distance between the limit plate and the middle of the conveyor belt. After the position of the limit plate is adjusted, the second limit bolt is tightened. When the height of the limit plate needs to be adjusted, the first limit bolt is loosened, and then the mounting plate is rotated. The second through hole will rotate relative to the first through hole, thereby adjusting the height position of the second through hole relative to the top surface of the conveyor belt. Moreover, during this process, both sets of mounting plates need to be adjusted simultaneously so that the two mounting plates in each set of limit brackets are parallel to each other.

[0039] The limiting plate 7 and the strip block are made of flexible material. Rubber plate support is preferred, but metal plate can also be used. If metal plate is used, the wall thickness is relatively thin, providing a certain degree of deformation capability. This type of limiting plate is relatively inexpensive, and it allows for snap-fit ​​installation and separation from the positioning rod.
