Description

Technical Field

[0001] This utility model relates to the field of plastic cup spraying technology, specifically a conveying device for plastic cup spraying. Background Technology

[0002] In the process of processing plastic cups, in order to improve the product grade and quality, the product surface needs to be sprayed with color to meet the different color requirements of different consumers. In order to improve the spraying quality and efficiency, spraying coloring of thermos cups or pots is carried out using a spraying production line.

[0003] During the spraying and transportation process, the cups typically need to be clamped and secured to maintain their position. This process requires manual clamping and release, which is cumbersome and time-consuming. Therefore, we propose a conveying device for spraying plastic cups. Utility Model Content

[0004] To address the shortcomings of existing spraying and transportation processes that generally require manual clamping and securing of cups, this invention provides a conveying device for spraying plastic cups. This device utilizes the weight of the cup to rotate two connecting rods into a V-shape, which then compresses the inner wall of the plastic cup, thus securing the cup. This solves the problems mentioned in the background section.

[0005] The technical solution of this utility model is implemented as follows: A conveying device for spraying plastic cups includes mounting frames symmetrically connected to the top of a base, a conveyor belt driven by a motor rotatably connected between the mounting frames, a support frame located above the conveyor belt and fastened to the top of the mounting frames, and a spraying mechanism connected to the inner top surface of the support frame; multiple sleeves rotatably connected to the conveyor belt are arranged vertically along the circumference, a second vertical rod is coaxially connected inside the sleeve, a first vertical rod is coaxially connected to the top of the second vertical rod, and the diameter of the first vertical rod is smaller than the diameter of the second vertical rod, a guide tube is coaxially sleeved on the first vertical rod, and a return spring coaxial with the first vertical rod is connected between the guide tube and the second vertical rod; symmetrical openings are provided on the outer wall of the sleeves, and sliders are symmetrically arranged in the openings, two sliders are respectively connected to the guide tube and the second vertical rod, and a connecting rod is rotatably connected to each slider, with the two connecting rods rotatably connected at their adjacent ends.

[0006] Optionally, two sets of guide mechanisms are symmetrically connected inside the support frame. Each set of guide mechanisms includes two U-shaped guide seats with their openings facing each other, and a sleeve is located between the two guide seats.

[0007] Optionally, a gear is coaxially connected to the sleeve located between the two guide seats, and a plurality of toothed plates that mesh with the gear are fastened to the side wall of one of the guide seats.

[0008] Optionally, the sleeve is symmetrically provided with a second connecting seat and a first connecting seat connected to it along the gear. The two ends of the second connecting seat are symmetrically connected with a first limiting plate, and the two ends of the first connecting seat are symmetrically connected with a second limiting plate. The two first limiting plates are engaged with the upper ends of the two guide seats, and the two second limiting plates are engaged with the lower ends of the two guide seats.

[0009] Optionally, the diameter of the first connecting seat is larger than the diameter of the second limiting plate.

[0010] Optionally, the two sets of guide seats are fastened to the top of the support frame by fastening brackets, and the sides of the guide seats that are far apart from each other are fixedly connected to the side wall of the support frame by fixing seats.

[0011] Optionally, a limit seat is coaxially connected to the top of the guide tube.

[0012] Optionally, the spraying mechanism includes a support base connected to the upper end of the fastener, with multiple spray nozzles symmetrically connected on both sides of the support base.

[0013] Compared with existing technologies, this invention utilizes the gravity of the cup to press the guide tube, which in turn presses the return spring, pushing the two connecting rods to form a V-shape. This V-shape compresses the inner wall of the plastic cup, thus fixing the cup in place. After spraying, when the cup is removed, the pressure on the guide tube decreases, and the two connecting rods return to their initial state under the elastic force of the return spring, allowing the cup to be removed. This invention not only has a simple structure but also effectively fixes the cup, greatly facilitating processing and avoiding manual pressing for fixation. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 6 This utility model provides a technical solution: a conveying device for spraying plastic cups, including mounting frames 2 symmetrically connected to the top of a base 3, a conveyor belt 10 rotatably connected between the mounting frames 2 via a motor 1, a support frame 6 located above the conveyor belt 10 and fastened to the top of the mounting frames 2, and a spraying mechanism connected to the inner top surface of the support frame 6, such as... Figure 3 As shown, the spraying mechanism includes a support base 13 connected to the upper end of the fastening frame 11. Multiple nozzles 12 are symmetrically connected on both sides of the support base 13. In actual use, the nozzles 12 are inclined to the support base 13 and are connected to the paint pumping mechanism through connecting pipes to ensure that the cup can be sprayed normally.

[0024] like Figure 2 , 5As shown in Figure 6, multiple sleeves 5 are circumferentially and vertically connected to the conveyor belt 10. A second vertical rod 25 is coaxially connected inside each sleeve 5. A first vertical rod 22 is coaxially connected to the top of the second vertical rod 25, and the diameter of the first vertical rod 22 is smaller than the diameter of the second vertical rod 25. A guide tube 8 is coaxially sleeved on the first vertical rod 22. A return spring 21, coaxial with the first vertical rod 22, is connected between the guide tube 8 and the second vertical rod 25. Openings 14 are symmetrically opened on the outer wall of each sleeve 5. Slider blocks 20 are symmetrically arranged inside each opening 14. Two sliders 20 are connected to the guide tube 8 and the second vertical rod 25 respectively. Each slider 20 is rotatably connected to a connecting rod 17. The two connecting rods 17 are rotatably connected at their closest ends. The top of the guide tube 8 is coaxially connected to a limiting seat 7. When the plastic cup is fitted onto the top of the guide tube 8, the guide tube 8 can be pressed under the weight of the cup. Under the pressing action, the two connecting rods 17 form a V-shaped structure. The V-shaped structure on both sides can squeeze the inner wall of the plastic cup, thus fixing the position of the cup. After the cup is removed, the pressure on the top of the guide tube 8 decreases, and the two connecting rods 17 can return to their initial state under the elastic force of the return spring 21, and then the cup can be removed.

[0025] like Figure 3 , 4 As shown, to achieve the rotation of the sleeve 5 and drive the cup to rotate, ensuring that the cup is fully coated, two sets of guide mechanisms are symmetrically connected inside the support frame 6. Each set of guide mechanisms includes two U-shaped guide seats 16, with their openings facing each other. The two sets of guide seats 16 are fastened to the top of the support frame 6 by fastening brackets 11. The sides of the guide seats 16 that are far apart from each other are fixedly connected to the side wall of the support frame 6 by fixing seats 15. The sleeve 5 is located between the two guide seats 16. A gear 4 is coaxially connected to the sleeve 5 between the two guide seats. Multiple toothed plates 18 that mesh with the gear 4 are fastened to the side wall of one of the guide seats 16. The conveyor belt 10 drives the sleeve 5 to move. After the sleeve 5 moves between the two guide seats 16, the gear 4 contacts the toothed plates 18 and the meshing action of the two can realize the rotation of the sleeve 5, which can drive the cup located at the top of the guide tube 8 to rotate. When the sleeve 5 moves out from between the two guide seats 16, the cup stops rotating, which makes it convenient to unload the coated cup.

[0026] In summary, during use, to ensure stable rotation of the sleeve 5 between the two guide seats 16, the conveying device for spraying plastic cups has a second connecting seat 23 and a first connecting seat 19 symmetrically connected to the gear 4 along the sleeve 5. The two ends of the second connecting seat 23 are symmetrically connected to the first limiting plate 9, and the two ends of the first connecting seat 19 are symmetrically connected to the second limiting plate 24. The two first limiting plates 9 are engaged with the upper ends of the two guide seats 16, and the two second limiting plates 24 are engaged with the lower ends of the two guide seats 16. The diameter of the first connecting seat 19 is larger than the diameter of the second limiting plate 24, which facilitates the support of the cup located on top of it and ensures the stable placement of the cup.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
