Description

Technical Field

[0001] The present invention belongs to the technical field of conveying equipment, and in particular relates to a conveying equipment used in a spraying production line. Background Art

[0002] In the prior art, the Chinese invention patent application number 202421102416.X discloses a conveying device for a spraying production line, which includes a frame with a motor installed at either end of the frame. The frame is composed of two oppositely arranged support frames, and both support frames are provided with chains... When the product that has completed spraying is placed on the conveyor belt of this application and transported to the next process, since the conveyor of this application is a metal woven mesh with a grid, the bottom of the product will not be unable to dry in time due to airtightness during the conveying process. Furthermore, a hair dryer is provided under the conveyor belt to blow air towards the product on the conveyor belt to accelerate the drying of the product, which solves the problem in the prior art that the existing conveying equipment for spraying production lines does not have a breathable structure. After spraying, the product is directly placed on the conveying equipment for transportation. The airtight conveying equipment causes the paint surface on the bottom of the product to dry very slowly.

[0003] However, the conveying equipment used in the spraying production line has the following problems during use: 1. When the sprayed product is conveyed on a metal mesh with a grid structure, although the metal mesh has a grid structure that can greatly increase the air permeability of the bottom of the product during conveyance, the bottom surface of the product still needs to be in contact with the metal mesh with a grid structure over a large area. The uneven surface of the metal mesh will cause indentations on the bottom paint surface of the product, thereby affecting the smoothness of the bottom paint surface of the product.

[0004] 2. When the sprayed products are conveyed on a metal woven mesh with a grid structure, several hair dryers below blow air upward to speed up the drying of the products above. However, the hair dryers are set at a low height, close to the ground, and the distance between the hair dryers below and the products above is relatively far. As a result, when the hair dryers below blow air to the products above, the wind blown upward from bottom to top over a long distance and a large range will greatly increase the floating of dust from the bottom to the upper layer. A large amount of floating dust adheres to the surface of the product, which will further affect the surface finish of the product. Summary of the Invention

[0005] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a conveying equipment for a spraying production line, which adopts a left-right split design. When the sprayed product is conveyed on it, the bottom of the product will not be blocked on a large scale, which is conducive to the ventilation and drying of the bottom of the product, and is not easy to cause indentations on the paint surface at the bottom of the product. At the same time, air is discharged upward through the left air outlet and the right air outlet to facilitate auxiliary drying of the product paint surface, and it is not easy to bring dust when the air is discharged at a close distance from the bottom of the product. In addition, the distance between the left conveying part and the right conveying part, as well as the air outlet length of the left air outlet and the right air outlet can be flexibly adjusted, which can be suitable for the conveying of products of different sizes.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a conveying device for a spraying production line, comprising a left conveying part and a right conveying part, the left conveying part and the right conveying part being distributed left and right, a motor being fixedly mounted on the outer side of the front end of each of the left conveying part and the right conveying part, a main gear disc being fixedly connected to the output end of the motor, a plurality of auxiliary gear discs being provided on the inner side of each of the left conveying part and the right conveying part, a support shaft being fixedly connected to the rear end of each of the auxiliary gear discs, a plurality of branch holes being opened on each of the left conveying part and the right conveying part, a support bearing being fixedly connected to the interior of each of the branch holes, and a rear end of the support shaft being fixedly connected to the inner wall of the support bearing, a toothed belt being provided on the inner side of each of the left conveying part and the right conveying part, and the toothed belt being meshed with the main gear disc and the auxiliary gear disc; The outside of the bottom end of the left conveying part is fixedly connected to the left leg, and the right legs are fixedly installed on both sides of the bottom end of the right conveying part.
