Description

Technical Field

[0001] This utility model relates to the field of drying equipment, and in particular to an energy-saving idler roller paint drying device. Background Technology

[0002] After being painted, existing idler rollers are usually dried in a drying tunnel (using electric heating to heat the air). The painted idler rollers automatically enter the drying tunnel inlet and pass through each temperature zone (preheating zone, curing zone, cooling zone) at a uniform speed under the drive of the conveyor chain (such as overhead chain, mesh belt chain, roller conveyor chain). After completing the curing process, they come out from the outlet.

[0003] During use, in order to enable the conveyor chain to transport continuously, the two ends of the drying tunnel are usually open structures. This causes a large amount of hot air to overflow from the inlet and outlet of the drying tunnel, resulting in energy waste. Utility Model Content

[0004] In view of the problem of heat overflow and energy waste at the inlet and outlet of the drying tunnel in the above or existing technologies, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A sealing component includes a drying tunnel, with shielding components provided on both the outer and front sides of the drying tunnel. A rotating connecting block is provided on the side of the shielding component near the drying tunnel channel. A connecting rod is rotatably connected inside the rotating connecting block, and a rotating slider is rotatably connected to the end of the connecting rod away from the rotating connecting block. An inner baffle is slidably connected to the outside of the rotating slider. A limiting component includes a fixing shell, which is fixedly connected to the side of the inner baffle near the drying tunnel. A rotating screw is rotatably connected inside the fixing shell, and a stop block is threaded onto the outside of the rotating screw.

[0006] As a preferred embodiment of the energy-saving idler roller paint drying device of this utility model, the shielding component includes an electric push rod, which is rotatably connected to the outside of the drying tunnel. A connecting plate is rotatably connected to one end of the electric push rod near the inlet / outlet of the drying tunnel. An outer baffle is fixedly connected to one side of the connecting plate near the drying tunnel channel. A limit shaft seat is rotatably connected to the center of the connecting plate.

[0007] As a preferred embodiment of the energy-saving idler roller paint drying device of this utility model, the limiting shaft seat is provided in four sets, and all four sets of the limiting shaft seat are fixedly connected to the outside of the drying tunnel.

[0008] As a preferred embodiment of the energy-saving roller paint drying device of this utility model, the inner baffle is internally connected to a limiting shaft, and the drying tunnel is internally fixedly connected to a rotation limiting strip.

[0009] As a preferred embodiment of the energy-saving idler roller paint drying device of this utility model, the top of the limiting shaft is fixedly connected to the inner side of the top of the drying tunnel, and the bottom of the limiting shaft is fixedly connected to the inner side of the bottom of the drying tunnel.

[0010] As a preferred embodiment of the energy-saving idler roller paint drying device of this utility model, a groove is provided at the corresponding position of the inner baffle and the rotating slider, and the rotating slider is slidably connected to the groove provided inside the inner baffle.

[0011] As a preferred embodiment of the energy-saving idler roller paint drying device of this utility model, the stop block is slidably connected inside the fixed shell, and a rectangular hole is opened at the corresponding position of the inner baffle and the stop block. The rectangular hole opened inside the inner baffle is set in the middle of the slide groove, and the stop block is slidably connected inside the rectangular hole opened inside the inner baffle.

[0012] The beneficial effects of this energy-saving idler roller paint drying device are as follows:

[0013] 1. By using the sealing components, the electric push rod pulls the connecting plate to rotate the outer baffle, achieving a sealing effect at the entrance and exit of the drying tunnel. At the same time, through the cooperation of the connecting rod and the rotating slider, the inner baffle rotates inside the drying tunnel, alternately sealing the tunnel. This prevents a large amount of hot air from escaping, reduces energy waste, and achieves energy-saving drying.

[0014] 2. By setting limit components and using adjustable blocks to control the limit of the inner baffle's internal slide groove, the rotating slider can be blocked as needed, thereby controlling the rotation of the inner baffle and achieving the effect of controlling the sealing of the inner baffle as needed.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1, referring to Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an energy-saving idler roller paint drying device, which can achieve the effect of sealing and blocking heat when the idler roller enters and exits inside the drying tunnel 10. It includes a sealing component and a drying tunnel 10. A shielding component 11 is provided on the outer side and the front side of the drying tunnel 10. A rotating connecting block 12 is provided on the side of the shielding component 11 near the channel of the drying tunnel 10. A connecting rod 13 is rotatably connected inside the rotating connecting block 12. A rotating slider 14 is rotatably connected to the end of the connecting rod 13 away from the rotating connecting block 12. An inner baffle 15 is slidably connected to the outside of the rotating slider 14.

[0025] Specifically, when the rollers enter the drying tunnel 10 via the conveyor chain, the shielding assembly 11 is used to drive the rollers to seal the outer inlet and outlet as each roller enters. The inner baffle 15 forms a cross-sealed space to prevent heat from overflowing. After the rollers enter the drying tunnel 10, the inlet and outlet are sealed again, and the inner seal is released simultaneously to reduce heat overflow and waste, thus achieving energy-saving effect during drying.

[0026] Furthermore, the shielding assembly 11 includes an electric push rod 111, which is rotatably connected to the outside of the drying tunnel 10. A connecting plate 112 is rotatably connected to one end of the electric push rod 111 near the inlet and outlet of the drying tunnel 10. An outer baffle 113 is fixedly connected to one side of the connecting plate 112 near the channel of the drying tunnel 10. A limiting pivot seat 114 is rotatably connected to the center of the connecting plate 112. Four sets of limiting pivot seats 114 are provided, and all four sets of limiting pivot seats 114 are fixedly connected to the outside of the drying tunnel 10.

[0027] Specifically, by driving the electric push rod 111, the output end of the electric push rod 111 can pull the outer rotating joint of the connecting plate 112 to rotate, so that the connecting plate 112 can be tilted up. The rotation of the connecting plate 112 is restricted by the limiting rotating shaft seat 114 at the center, so that the outer baffle 113 can be rotated open, releasing the seal on the inlet and outlet of the drying tunnel 10, and facilitating the normal driving of the conveyor chain to drive the idler rollers in and out of the drying tunnel 10.

[0028] Preferably, the inner baffle 15 is rotatably connected to a limiting shaft 16, and the drying tunnel 10 is fixedly connected to a rotation limiting strip 17. The top of the limiting shaft 16 is fixedly connected to the inner top of the drying tunnel 10, and the bottom of the limiting shaft 16 is fixedly connected to the inner bottom of the drying tunnel 10. A sliding groove is provided at the corresponding position of the inner baffle 15 and the rotating slider 14, and the rotating slider 14 is slidably connected to the sliding groove provided inside the inner baffle 15.

[0029] It should be noted that by limiting the rotation of the inner baffle 15 by the limiting shaft 16, the inner baffle 15 can rotate stably inside the drying tunnel 10, thereby causing the junction ends of the two inner baffles 15 to meet and touch, forming a sealed structure inside the drying tunnel 10. At the same time, the rotation limiting strip 17 can limit the rotation angle of the inner baffle 15, ensuring that the two inner baffles 15 can meet at a point normally. Meanwhile, the rotating slider 14 sliding inside the inner baffle 15 can prevent the rotation angle of the inner baffle 15 from following the rotation angle of the outer baffle 113, ensuring stability.

[0030] When the drying tunnel 10 is used to dry the paint on the idler rollers, it is initially in a sealed state. Since the idler rollers will always follow the conveyor chain, when the idler rollers reach the inlet of the drying tunnel 10 through the conveyor chain, the electric push rod 111 is first driven to shorten the output end of the electric push rod 111. Through the rotation limit of the limit shaft seat 114, the connecting plate 112 is tilted up. The connecting plate 112 starts to drive the outer baffle 113 to rotate, so that the inlet end of the drying tunnel 10 is opened. At this time, the idler rollers will normally enter the inner side of the outer baffle 113 and gradually enter the internal space of the drying tunnel 10.

[0031] When the outer baffle 113 starts to rotate, the connecting rod 13 pulls the rotating slider 14 first, causing the rotating slider 14 to slide. When the rotating slider 14 slides to the center of the groove, it is resisted by the stop block 22. At this time, the inner baffle 15 is pulled to rotate under the limit of the limiting shaft 16. As the outer baffle 113 rotates, the inner baffle 15 rotates to the center of the drying tunnel 10. At this time, the rotation of the inner baffle 15 is limited by the rotating limiting strip 17. The inner baffles 15 on both sides meet and seal the internal space of the drying tunnel 10 to prevent heat loss. When the roller has completely entered the interior of the drying tunnel 10, the electric push rod 111 is driven again to push the connecting plate 112 in the opposite direction, so that the outer baffle 113 rotates to cover the inlet and outlet of the drying tunnel 10. At this time, the inner baffle 15 is reset due to the push of the connecting rod 13, the inlet and outlet of the drying tunnel 10 are sealed, and the roller normally enters the depth of the drying tunnel 10.

[0032] When the sealing component is used, an unsealed space is opened inside the drying tunnel 10 and at the top of the inner baffle 15. This space is used for the normal passage of the conveyor chain and is matched with the size of the conveyor chain, so there will be no excessive heat overflow. The overflowing heat will not affect the interior of the drying tunnel 10, so there will be no heat waste. At the same time, using this component, the process of opening the outer baffle 113 - entering the idler roller - blocking the inner baffle 15 - entering the drying tunnel 10 - sealing the outer baffle 113 - ending the blocking of the inner baffle 15 can be repeated, thereby minimizing energy waste and not affecting the inlet and outlet of the idler roller. The same operation is also repeated at the outlet end of the drying tunnel 10.

[0033] Example 2, refer to Figures 5-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a limiting component for an energy-saving idler roller paint drying device based on embodiment 1. This solves the problem that the inner baffle 15 affects the movement of the idler rollers during continuous and dense idler roller conveying. It includes a limiting component, including a fixed shell 20. The fixed shell 20 is fixedly connected to the side of the inner baffle 15 near the drying tunnel 10. A rotating screw 21 is rotatably connected inside the fixed shell 20. A stop block 22 is threadedly connected to the outside of the rotating screw 21. The stop block 22 is slidably connected inside the fixed shell 20. A rectangular hole is opened at the corresponding position of the inner baffle 15 and the stop block 22. The rectangular hole opened inside the inner baffle 15 is located in the middle of the slide groove, and the stop block 22 is slidably connected inside the rectangular hole opened inside the inner baffle 15.

[0034] Specifically, by inserting a Phillips screwdriver into the rotating screw 21 and rotating the screw 21, the stop block 22 can enter the inner baffle 15, ending the limitation on the slide groove. This allows the rotating slider 14 to slide inside the entire slide groove, thus preventing the inner baffle 15 from forming a sealed space following the rotation of the outer baffle 113.

[0035] In use, when the conveyor chain transports the idler rollers in a dense manner, the rotating screw 21 can be rotated to drive the stop block 22 into the inner baffle 15. Since the stop block 22 is initially located at the center of the chute, it will block the sliding of the rotating slider 14. When the slider slides halfway, it will be pulled by the connecting rod 13 to rotate the inner baffle 15. When the stop block 22 enters the inner baffle 15, the rotating slider 14 will slide through the entire chute when the connecting rod 13 pulls it, thus preventing the inner baffle 15 from rotating during sealing. At this time, multiple consecutive and dense idler rollers will enter the drying tunnel 10. After the idler rollers enter the drying tunnel 10 and fill it, the electric push rod 111 can be driven to seal the drying tunnel 10 until the paint is dried and then released.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
