Description

Technical Field

[0001] The utility model relates to the technical field of plate transport devices, in particular to an umbrella-tooth transport structure for plate-type furniture. Background Art

[0002] In the production process of panel furniture factories, conveyor lines are required to quickly and automatically transport panels between processing equipment. When the speed of the panels changes due to resistance, the existing chain conveyor will stagnate, while the roller speed of the chain conveyor remains at the original speed. As a result, excessive friction between the panels and the rollers will cause scratches, and the transportation will be unstable. The surface quality of the panels cannot be well guaranteed and a lot of noise will be generated. Therefore, how to solve the problems of instability caused by resistance during the advancement of the panels, collisions of panels, severe scratches, etc. needs to be further resolved. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] In order to overcome the shortcomings of the prior art, a bevel-tooth conveying structure for panel furniture is proposed, which can reduce the transportation speed when the panel encounters resistance during its forward movement, thereby ensuring the surface quality of the panel.

[0005] (II) Technical solution

[0006] The utility model is achieved through the following technical scheme: the utility model proposes an umbrella-tooth conveying structure for panel furniture, including a driving shaft driven to rotate by a motor, a driven shaft arranged in parallel with the driving shaft and capable of synchronous rotation, a plurality of conveying rollers for conveying panels are arranged at intervals between the driving shaft and the driven shaft, a plurality of intermediate umbrella-tooth structures are arranged on the driving shaft and the driven shaft, and the conveying rollers realize self-slowing of the panel conveying speed through the intermediate umbrella-tooth structures connected thereto in transmission.

[0007] Furthermore, the driving shaft and the driven shaft achieve synchronous rotation via a transmission roller.

[0008] Furthermore, a single-side end surface of the conveying roller is provided with transmission bevel gears, which are alternately arranged between two adjacent conveying rollers and are respectively connected to the driving shaft and the driven shaft through the transmission bevel gears.

[0009] Furthermore, the intermediate bevel gear structure includes a first fixing ring and a second fixing ring which are arranged at intervals, an intermediate bevel gear which meshes with the transmission bevel gear for transmission and a spring which applies pressure to the intermediate bevel gear and acts on the first fixing ring are arranged between the first fixing ring and the second fixing ring, friction plates for switching the transmission state are arranged between the first fixing ring and the intermediate bevel gear and between the second fixing ring and the spring, and a thrust ball bearing for absorbing the speed difference is arranged at one end of the spring close to the intermediate bevel gear.

[0010] (III) Beneficial effects

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model mentions an umbrella-tooth conveying structure for panel furniture. When the panel encounters resistance during its forward movement, the intermediate umbrella-tooth structure uses the principle of slippage to prevent the driving shaft and the driven shaft from interfering with the rotation of the conveying roller while they continue to rotate. This causes the forward speed of the panel to automatically slow down or stop depending on the size of the resistance. The panel will not be scratched by excessive friction with the conveying roller, and transportation will be smooth, thereby ensuring the surface quality of the panel and improving the yield rate of the panel.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] like Figure 1-Figure 3 A bevel gear conveying structure for panel furniture is shown, and the shaft support frame 10 is an aluminum profile structure, including two parallel aluminum profiles, each aluminum profile is provided with a number of bearing seats 11 spaced apart along its length direction. In this embodiment, the number of bearing seats 11 is 5, which are spaced apart at the front end, middle end and rear end of the aluminum profile, respectively. The driving shaft 2 and the driven shaft 3 are inserted into the bearing seats 11, and bevel gears are provided at the front ends of the driving shaft 2 and the driven shaft 3. Gears meshing with the bevel gears are provided at the two end faces of the driving roller 6. Therefore, when the driving shaft 2 is driven by the motor to rotate, the driven shaft 3 can rotate synchronously with the driving shaft 2.

[0019] The conveying roller 4 is arranged between the driving shaft 2 and the driven shaft 3. Both ends of the conveying roller 4 are fixed on the aluminum profile. A transmission bevel gear 7 is arranged on the single-side end face of the conveying roller 4. Two adjacent conveying rollers 4 are alternately arranged between the driving shaft 2 and the driven shaft 3. A plurality of intermediate bevel gear structures 5 connected to the transmission bevel gear 7 are arranged on the driving shaft 2 and the driven shaft 3. The intermediate bevel gear structure 5 includes a first fixing ring 51 and a second fixing ring 52. The first fixing ring 51 and the second fixing ring 52 are arranged at intervals and can rotate with the driving shaft 2 and the driven shaft 3. An intermediate bevel gear 53 meshing with the transmission bevel gear 7 is arranged between the first fixing ring 51 and the second fixing ring 52. The intermediate bevel gear 53 is pressed against the first fixing ring 51 by a spring 54. The first fixing ring 51 and the intermediate bevel gear 53 and the second fixing ring 52 are arranged at intervals. A friction plate 8 is provided between 52 and the spring 54. The rotation of the first fixed ring 51 can be transmitted to the middle bevel gear 53 through the friction plate 8, and then transmitted to the transmission bevel gear 7 by the middle bevel gear 53 to drive the conveying roller 4 to rotate. When the speed of the transmission bevel gear 7 slows down or stops, due to the existence of the friction plate 8, the first fixed ring 51 will continue to rotate, and slippage will occur between the middle bevel gear 53 and the friction plate 8. The state switching between transmission and slippage is realized by the friction plate 8. A thrust ball bearing 9 is provided between the spring 54 and the middle bevel gear 53. When the speed of the middle bevel gear 53 slows down or stops, the spring 54 continues to rotate with the second fixed ring 52. The thrust ball bearing 9 can absorb the speed difference between the spring 54 and the middle bevel gear 53, and keep the middle bevel gear 53 in a slipping state when it is subjected to resistance.

[0020] The utility model discloses a bevel gear conveying structure for panel furniture. When it is used specifically, under normal circumstances, the driving shaft 2 drives the driven shaft 3 to rotate and then drives the conveying roller 4 to rotate, and the panel is driven to move forward through the conveying roller 4. When the advancement of the panel is hindered by other panels or external forces and becomes slow, the rotation speed of the conveying roller 4 slows down or stops. The resistance encountered by the transmission bevel gear 7 at this time will be greater than the driving force of the middle bevel gear structure 5, so that the speed of the middle bevel gear 53 slows down or stops. Under the action of the friction plate 8, the middle bevel gear 53 is in a slipping state, and the driving shaft 2 and the driven shaft 3 continue to drive the first fixed ring 51 and the second fixed ring 52 to rotate. Therefore, the transmission system will not be affected by the resistance of the panel, but the speed of the entire device can be slowed down, protecting the panel from damage caused by excessive speed during operation. When the cause of the obstruction of the panel is eliminated, the resistance encountered by the transmission bevel gear 7 becomes smaller, and the friction plate 8 switches the middle bevel gear 53 to the transmission state. The transmission bevel gear 7 can restore the rotation speed driven by the middle bevel gear 53, and the panel will continue to move forward at the original speed.

Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
