A roller conveyor for steel plate pretreatment

Abstract

This utility model relates to the field of roller conveyor technology, specifically a roller conveyor for steel plate pretreatment. It includes side plates, with multiple round rods rotatably connected between the adjacent sides of two side plates. A transmission roller is fixedly sleeved on the outer side of each round rod. A second motor drives the transmission roller to rotate via the round rods, thus conveying the steel plate. Starting a first motor drives a second gear to rotate, which in turn drives a first gear to rotate. The first gear, through a circular tube, drives a screw to move. The screw, through a rectangular plate, drives a horizontal plate to move, which in turn drives multiple positioning wheels to move. The steel plate is conveyed between these positioning wheels, which effectively position the steel plate, giving the roller conveyor a positioning function during use. This facilitates the effective positioning of steel plates of different specifications, reducing the likelihood of misalignment during transport and eliminating the need for manual adjustment, thereby improving conveying efficiency.

Description

Technical Field

[0001] This utility model relates to the field of roller conveyor technology, specifically a roller conveyor for steel plate pretreatment. Background Technology

[0002] Steel plate pretreatment refers to the process of treating the surface of steel plates before processing. The main process is as follows: loading plate → shot blasting → spraying zinc-rich primer → paint drying → unloading plate. During the steel plate pretreatment process, the plate needs to be conveyed by roller conveyor.

[0003] However, some existing steel plate pretreatment roller conveyors do not have a positioning function during use, making it inconvenient to effectively position steel plates of different specifications. During the conveying process of steel plates on the roller conveyor, the position of the steel plates is prone to change, requiring manual adjustment and reducing the conveying efficiency. To address these issues, we propose a steel plate pretreatment roller conveyor. Utility Model Content

[0004] The purpose of this utility model is to provide a roller conveyor for steel plate pretreatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roller conveyor for steel plate pretreatment, comprising side plates, a plurality of round rods rotatably connected between the two side plates on their adjacent sides, a transmission roller fixedly sleeved on the outer side of the round rods, a vertical plate fixedly connected to the top of the side plates, a rectangular plate on the outer side of the vertical plate, a horizontal plate fixedly connected to the bottom of the rectangular plate, a plurality of positioning wheels rotatably connected to the adjacent sides of the two corresponding horizontal plates, a screw fixedly connected to the outer side of the rectangular plate, a circular tube threadedly sleeved on the outer side of the screw, the vertical plate rotatably sleeved on the outer side of the corresponding circular tube via a bearing, a first gear fixedly sleeved on the outer side of the circular tube, a second gear meshing on the outer side of the first gear, and an L-shaped plate fixedly connected to the outer side of the vertical plate.

[0006] More preferably, a first motor is fixedly connected to the inner wall of the L-shaped plate, and the output shaft end of the first motor is fixedly connected to the outer side of the second gear.

[0007] More preferably, each of the two rectangular plates has two square rods fixedly connected to its opposite side, and the vertical plate is slidably sleeved on the outside of the corresponding two square rods.

[0008] More preferably, a fixing box is fixedly connected to the front side of one of the front side plates, and the end of the round rod extends into the fixing box.

[0009] More preferably, a transmission wheel is fixedly sleeved on the outer side of the round rod, and the two corresponding transmission wheels are connected by the same belt.

[0010] More preferably, a second motor is fixedly connected to the outer side of one of the rear side plates, and the end of the output shaft of the second motor is fixedly connected to the rear end of one of the round rods on the right side.

[0011] More preferably, the bottom of the side plate is fixedly connected to two support plates, and the bottom of the support plates is fixedly connected to a support base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The second motor of this utility model drives the transmission roller to rotate through the round rod. The rotation of the transmission roller conveys the steel plate. The first motor starts and drives the first gear to rotate through the second gear. The first gear drives the screw to move through the round tube. The screw drives the horizontal plate to move through the rectangular plate. The horizontal plate drives multiple positioning wheels to move. The steel plate is transmitted between the multiple positioning wheels. The setting of the positioning wheels has the effect of positioning the steel plate. This gives the roller conveyor a positioning function during use, which is convenient for effectively positioning steel plates of different specifications. The steel plate is less likely to be misaligned during the conveying process on the roller conveyor. It does not require manual adjustment and improves the conveying efficiency.

An L-shaped plate 12 is fixedly connected. A second motor 17 drives a transmission roller 3 to rotate via a round rod 2. The transmission roller 3 rotates to convey the steel plate. The first motor 13 starts and drives a first gear 10 to rotate via a second gear 11. The first gear 10 rotates via a round tube 9 to move a screw 8. The screw 8 moves a horizontal plate 6 via a rectangular plate 5. The horizontal plate 6 moves multiple positioning wheels 7. The steel plate is transmitted between the multiple positioning wheels 7. The positioning wheels 7 are used to position the steel plate, giving the roller conveyor a positioning function during use. This facilitates the effective positioning of steel plates of different specifications. The steel plate is less likely to be misaligned during the conveying process on the roller conveyor, eliminating the need for manual adjustment and improving conveying efficiency.

[0027] In operation, this invention works as follows: A steel plate is placed on top of multiple transmission rollers 3. Then, the second motor 17 is started. The second motor 17 drives a circular rod 2 to rotate. The rotation of one circular rod 2 drives a transmission wheel to rotate. The rotation of one transmission wheel, via a belt 16, drives another transmission wheel to rotate. The rotation of the other transmission wheel drives another circular rod 2 to rotate, causing the circular rod 2 to drive the transmission rollers 3 to rotate. The rotation of the transmission rollers 3 conveys the steel plate. When positioning steel plates of different specifications is required, the first motor 13 is started. The first motor 13 drives a second gear 11 to rotate. The rotation of the second gear 11 drives a first gear 10 to rotate. The rotation of the first gear 10 drives the corresponding circular tube 9 to rotate. The rotation of the circular tube 9 drives...
