Technical Field

[0001] The present invention belongs to the technical field of plastic cup production, and particularly relates to a plastic cup production device. Background Art

[0002] In the plastic products industry, plastic cups, as a common and widely used container, their production efficiency and product quality are crucial for the market competitiveness of enterprises. With the continuous growth of market demand and the increasing improvement of consumers' requirements for product quality, plastic cup production enterprises are facing multiple challenges of improving production efficiency, reducing labor costs, and enhancing product consistency and stability.

[0003] In the traditional plastic cup production process, the formed plastic cups usually need to be collected and stacked by a mechanical device for subsequent processing. Although the existing mechanical devices have improved the collection efficiency to a certain extent, the collected plastic cups are divided into multiple groups, and workers need to remove and stack the multiple groups of plastic cups, which has a high labor intensity. Therefore, we provide a plastic cup production device to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a plastic cup production device to solve the problems raised in the background art.

[0005] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows: A plastic cup production device includes a frame. Three rotating shafts are rotatably installed in the frame. The three rotating shafts are arranged in sequence from left to right. The left rotating shaft and the middle rotating shaft are arranged on the same horizontal plane. The horizontal plane of the right rotating shaft is lower than the horizontal planes of the left two rotating shafts. A number of conveying wheels are installed on the three rotating shafts. The conveying wheels of the three rotating shafts are commonly connected with a conveyor belt. There are two conveyor belts provided for the conveying wheels. There is a conveying channel left between the adjacent two conveyor belts on the adjacent two conveying wheels. The conveying channel is used for conveying plastic cups. An L-shaped guiding plate matching the conveying channel is installed at the left end of the frame. The L-shaped guiding plate is inclined. Both sides of the upper end of the L-shaped guiding plate are connected with guide rails. The ends of the guide rails are attached to the left end of the conveyor belt. A pushing block is arranged on the side wall of the L-shaped guiding plate. The frame is equipped with a conveying component located below the L-shaped guiding plate.

[0006] A linear rail is arranged at the front side of the bottom of the L-shaped guiding plate.

[0007] A motor is installed at the front side of the frame. The output shaft of the motor is in transmission connection with the left rotating shaft.

Specific embodiments

[0017] In order to enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] As Figures 1-7 shown, a plastic cup production device of the present invention includes a frame 1, and three groups of rotating shafts 11 are rotatably installed in the frame 1. The three groups of rotating shafts 11 are arranged in sequence from left to right. The left rotating shaft 11 and the middle rotating shaft 11 are arranged on the same horizontal plane, and the horizontal plane of the right rotating shaft 11 is lower than the horizontal planes of the left two rotating shafts 11. A number of conveying wheels 12 are installed on the three groups of rotating shafts 11; The conveying wheels 12 of the three groups of rotating shafts 11 are jointly connected with a conveyor belt 13. There are two groups of conveyor belts 13 for the conveying wheels 12, and a conveying channel is left between the adjacent two groups of conveyor belts 13 on the adjacent two conveying wheels 12. The conveying channel is used for conveying plastic cups; An L-shaped material guiding plate 14 matching the conveying channel is installed at the left end of the frame 1. The L-shaped material guiding plate 14 is inclined. Both sides of the upper end of the L-shaped material guiding plate 14 are connected with guide rails 15. The ends of the guide rails 15 are attached to the left end of the conveyor belt 13. A pushing block 16 is arranged on the side wall of the L-shaped material guiding plate 14; The frame 1 is provided with a conveying assembly located below the L-shaped material guiding plate 14.

[0019] The conveying channel formed by the adjacent two groups of conveyor belts matches the size of the plastic cup. The body of the plastic cup can fall into the conveying channel, while the rim of the plastic cup will hang on the two conveyor belts 13; When one set of rotating shafts 11 rotates, it can drive the other two sets of rotating shafts 11 to rotate synchronously through the conveyor belt 13. When the conveyor belt 13 moves, it can convey the plastic cups. The frame 1 is arranged on one side of the plastic cup forming device. The movement of the conveyor belt 13 is realized by the rotation of the conveying wheels 12 on the rotating shafts 11. When the plastic cup is formed, it will fall inside the right side of the frame 1. A number of conveyor belts 13 block the plastic cups. The body of the plastic cup will fall into the conveying channel, and the rim of the plastic cup is hooked on the two conveyor belts 13. The plastic cups move from right to left and tilt upward under the conveyance of the conveyor belts 13. The conveyor belts 13 are inclined, so that the plastic cups that do not fall into the conveying channel will automatically roll down to the right end of the frame 1. After the plastic cups fall into the conveying channel, they can be conveyed to the left. When the plastic cups are conveyed to the left rotating shaft 11 by the conveyor belts 13, since the guide rail 15 is attached to the conveyor belt 13, when the plastic cups move to the guide rail 15, they can be directly connected to the guide rail 15. Also, because the guide rail 15 is inclined as a whole, after the plastic cups are located on the guide rail 15, due to the previous inertia and their own gravity, they will move along the inclined guide rail 15 to the L-shaped material guide plate 14. One side of the body of the plastic cup is blocked by the push block 16 of the L-shaped material guide plate 14, which will push the plastic cup to tilt forward. The tilted plastic cups roll down to the conveying assembly, and the conveying assembly is used to convey the plastic cups with the openings facing forward. With such a design, the plastic cups conveyed by multiple sets of conveyor belts 13 can be uniformly conveyed onto the conveying assembly, and the conveying assembly is used to stack the plastic cups with multiple openings facing forward, that is, only one set of stacked plastic cups will be formed. Compared with the existing equipment where multiple sets of plastic cups are stacked and then the staff removes and stacks the multiple sets of plastic cups, this application with one set of plastic cups can simplify the work process and reduce the work intensity of the staff. Moreover, the one set of plastic cups formed in this application can be connected to the conveying track in the workshop to convey the plastic cups to the next processing equipment for processing, eliminating the need for manual handling and improving the processing efficiency.

[0020] A linear rail 141 is arranged on the front side at the bottom of the L-shaped material guide plate 14; when the plastic cups are tilted on the L-shaped material guide plate 14, the rims of the plastic cups will be located inside the linear rail 141, which can make the plastic cups roll down along the L-shaped material guide plate 14 to avoid the deviation of the position of the plastic cups themselves.

[0021] A motor 2 is installed on the front side of the frame 1, and the output shaft of the motor 2 is in transmission connection with the left rotating shaft 11; the motor 2 is used to drive the left rotating shaft 11 to rotate, thereby driving the conveyor belt 13 to move and realizing the conveyance of the plastic cups.

[0022] The conveying component includes a mounting bracket 21 connected to the frame 1. First driving wheels 22 are rotatably mounted on both the front and rear sides of the mounting bracket 21. A first transmission belt 23 is provided between the two first driving wheels 22. A transmission member is provided between the first driving wheel 22 and the left shaft 11. A plastic cup collection guide 24 is provided at the front end of the frame 1; The transmission member includes a second driving wheel 3 connected to the left shaft 11. A third driving wheel 31 is rotatably mounted on the frame 1. A second transmission belt 33 is provided between the second driving wheel 3 and the third driving wheel 31. The third driving wheel 31 is connected to a first bevel gear 34. The first driving wheel 22 is connected to a second bevel gear 35 that meshes with the first bevel gear 34; When the device is working, the left shaft 11 rotates, driving the second driving wheel 3 to rotate. The second transmission belt 33 can drive the third driving wheel 31 to rotate, and then the first bevel gear 34 provided on the third driving wheel 31 rotates. Since the second bevel gear 35 connected to the first driving wheel 22 meshes with the first bevel gear 34, the first driving wheel 22 is driven to rotate, realizing the movement of the first transmission belt 23. When the plastic cup rolls onto the first transmission belt 23, the first transmission belt 23 can convey the plastic cup forward and collect it in the plastic cup collection guide 24; The diameter of the second driving wheel 3 is larger than that of the third driving wheel 31. Therefore, the rotation speed of the third driving wheel 31 is faster, which can make the first transmission belt 23 move faster and prevent the plastic cups from stacking on the first transmission belt 23; Furthermore, a limiting baffle is provided on the left side of the mounting bracket 21 to limit and block the plastic cups that fall onto the first transmission belt 23 and prevent the plastic cups from falling.

[0023] A vertical rod 4 is provided at the front end of the mounting bracket 21. The vertical rod 4 is rotatably mounted with a pressing wheel 41 through a rotating rod. The end of the rotating rod is connected to a fourth driving wheel 42. The second bevel gear 35 is connected to a first gear 43. A second gear 44 that meshes with the first gear 43 is rotatably mounted on the vertical rod 4. The second gear 44 is connected to a fifth driving wheel 45. A third transmission belt 46 is provided between the fourth driving wheel 42 and the fifth driving wheel 45; Similarly, when the second bevel gear 35 rotates, it drives the first gear 43 to rotate. Since the first gear 43 meshes with the second gear 44, the second gear 44 can be driven to rotate, and then the fifth driving wheel 45 is driven to rotate. The fourth driving wheel 42 is driven to rotate through the third transmission belt 46, thus realizing the rotation of the pressing wheel 41. The setting of the first gear 43 and the second gear 44 can change the rotation direction of the pressing wheel 41; The width of the plastic cup collection guide rail 24 is slightly smaller than the diameter of the plastic cup. When the plastic cup enters the plastic cup collection guide rail 24, the plastic cup will be resisted and unable to move forward by itself. When another plastic cup enters the plastic cup collection guide rail 24, its opening will enter the body of the previous plastic cup for cup stacking. The rotation of the pressing wheel 41 can contact the rim of the plastic cup and push the plastic cup into the plastic cup collection guide rail 24, so that the two plastic cups can overlap more completely and the collection of plastic cups can be realized.

[0024] A rotating shaft 5 is rotatably installed on the frame 1 above the middle rotating shaft 11. The rotating shaft 5 is provided with a material pushing brush 51. The front end of the rotating shaft 5 is connected with a third gear 52. The middle rotating shaft 11 is connected with a fourth gear 53. The third gear 52 and the fourth gear 53 are connected by an idle gear; when the left rotating shaft 11 rotates, it can drive the middle rotating shaft 11 to move synchronously. Through the transmission connection between the fourth gear 53 and the third gear 52, the rotation of the rotating shaft 5 is realized, and the material pushing brush 51 is driven to rotate. The material pushing brush 51 can push down the plastic cups that have not entered the conveying channel, so that the plastic cups fall downward to the lower side of the conveyor belt 13, comb and stir the plastic cups, and facilitate the plastic cups to be in a vertical state in the conveying channel.

Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
