Description

TECHNICAL FIELD

[0001] The utility model relates to tea drying equipment technical field, especially to a tea drying machine's mesh improvement structure. BACKGROUND

[0002] According to the manufacturing process of traditional tea, after picking, drying, rolling and other steps, it needs to go through the drying process. The control of temperature and the drying degree of the drying tea are related to the quality of the tea. If the drying degree of the tea is uneven, it will seriously affect the flavor of the tea. Therefore, the drying of tea is an important step for tea makers. The traditional tea drying process is carried out manually, which not only consumes manpower, but also cannot maintain the average degree of turning and stirring the tea. Therefore, tea drying machines are used to replace the drying operation. Two parallel continuous guide rails are arranged in a box body, and a plurality of meshes are arranged continuously on the two guide rails. The two ends of the mesh are connected by a chain conveyor belt and move on the guide rail under the driving of the chain belt. The tea is placed on the mesh. High-temperature gas is supplied to the box body. The moisture of the tea will be evaporated by the high-temperature gas during the movement of the tea on the guide rail, thereby achieving the purpose of dehydration. However, when the above-mentioned tea drying machine performs the tea drying operation, the tea will overlap when placed on the mesh, which cannot be evenly dried, thereby reducing the drying effect. The present application is a modified design of the mesh structure of the drying machine.

[0003] Therefore, based on years of experience in manufacturing, developing and designing related products, the present application is designed and evaluated to solve the above-mentioned problems. CONTENT OF THE UTILITY MODEL

[0004] The technical problem to be solved by the present application is to provide a mesh improvement structure for a tea drying machine, which includes a mesh. The left and right ends of the mesh are provided with a roller. The roller penetrates the shaft center to provide a shaft. A limiting seat and a limiting piece are arranged on the upper and lower surfaces of the two ends of the mesh to further limit the rotation of the roller at the two ends of the mesh. The limiting seat has a thickness and a weight block is arranged on one side of the limiting seat. The weight block is arranged on the edge of the mesh.

[0005] Preferably, the left and right ends of the mesh are provided with a roller slot for containing the roller. The roller slot is in the shape of a cross hole and has a long slot and two shaft limiting grooves symmetrically formed at the center of the two long edges of the long slot. Two limiting protrusions are arranged on both sides of the long slot.

[0006] Preferably, the limiting seat is provided with a lower roller through hole penetrating through the upper and lower surfaces, and the lower roller through hole is provided with two wheel shaft grooves on the symmetrical two sides for positioning the wheel shaft, the limiting sheet is provided with an upper roller through hole penetrating through the upper and lower surfaces, and the upper roller through hole is provided with two wheel shaft cover plates on the symmetrical two sides for covering and positioning the wheel shaft, the thickness of the limiting seat is smaller than the radius of the roller, so that the bottom end of the roller can pass out of the lower roller through hole, and the limiting seat and the limiting sheet are relatively combined and fixed by rivets, so that the roller is rotatably limited between the limiting seat and the limiting sheet.

[0007] Preferably, the thickness of the weight block is greater than the thickness of the limiting seat, so that the weight block is limited against the end of the mesh.

[0008] Preferably, the mesh is provided with a hollow cylinder on the front and rear sides, the width of the weight block is greater than the width of the limiting seat, and one end of the weight block is provided with a shaft column and penetrates into the hollow cylinder, and the weight block is further provided with an axial through hole penetrating through the center of the shaft column for connecting with a pin of the chain, so that the pin serves as the axis for the mesh to swing down when the mesh is in the down position.

[0009] Compared with the prior art, when the mesh is provided with rollers at both ends, the weight design of the limiting seat and the weight block can quickly and smoothly achieve the swinging down of the mesh when the mesh carries tea leaves for drying operation and the two chains are displaced and moved to a down position, so that the tea leaves are effectively turned over, and the efficiency of the mesh operation and the drying operation is improved.

[0023] In order to make the purpose, features and effects of the present invention more comprehensible and recognizable, the following will be described in detail with reference to the accompanying drawings:

[0024] First, as shown in FIGS. 1 and 2, a mesh improvement structure of a tea dryer includes a mesh 10, both ends of which are provided with a roller 20 penetrating through the shaft center to be provided with an axle 21, and a limiting seat 30 and a limiting sheet 40 are oppositely arranged on the upper and lower surfaces of both ends of the mesh 10 to further rotatably limit the roller 20 at both ends of the mesh 10, and the limiting seat 30 has a thickness and is provided with a weight block 31 on one side, which is arranged against the end edge of the mesh 10, so that the mesh 10 is designed to be weighted through the limiting seat 30 and the weight block 31.

[0025] As shown in FIGS. 1, 2, 3 and 4, both ends of the mesh 10 are provided with a roller slot 11 for containing the roller 20, the roller slot 11 is a cross hole with a long slot 111 and two axle limiting grooves 112 symmetrically formed at the center of two long sides of the long slot 111, and two limiting protrusions 113 are further arranged on both sides of the two axle limiting grooves 112 towards the long slot 111, the limiting seat 30 is provided with a lower roller through hole 32 penetrating through the upper and lower surfaces, and two axle slots 33 are arranged on both sides of the lower roller through hole 32 to cross and position the axle 21, the thickness of the limiting seat 30 is smaller than the radius of the roller 20, so that the bottom end of the roller 20 can penetrate out of the lower roller through hole 32, the limiting sheet 40 is provided with an upper roller through hole 41 penetrating through the upper and lower surfaces, and two axle cover plates 42 are arranged on both sides of the upper roller through hole 41 to cover and position the axle 21, and finally a plurality of rivets 43 are used to oppositely combine and fix the limiting seat 30 and the limiting sheet 40, so that the roller 20 is rotatably limited between the limiting seat 30 and the limiting sheet 40.

[0026] The structure of the embodiment is shown in FIGS. 3-6. The thickness of the weight block 31 is greater than that of the limiting seat 30, so that the weight block 31 is limited against the end of the mesh 10. The limiting seat 30 and the weight block 31 are made of metal, preferably cast iron. The mesh 10 has a hollow cylinder 12 on each of the front and rear sides. The width of the weight block 31 is greater than that of the limiting seat 30. The weight block 31 has a shaft column 311 protruding from one end and penetrating into the hollow cylinder 12. The shaft column 311 has a shaft hole 312 penetrating through the center of the shaft column 311. The mesh 10 is arranged between two symmetrical chains 50 and is driven by the chains 50 to move the rollers 20 along a circular track A. The circular track A has a lower position A1. The chains 50 are connected to the shaft holes 312 of the weight blocks 31 at two ends of the mesh 10 through a plurality of rotating shafts 51. The rotating shafts 51 serve as the shafts for the mesh 10 to swing down at the lower position A1. When the mesh 10 moves along with the chains 50 to the lower position A1, the mesh 10 rolls along the circular track A by the rollers 20. When the mesh 10 passes through the lower position A1 of the circular track A, the rollers 20 are suspended and swing down by the rotating shafts 51. The weight of the limiting seat 30 and the weight block 31 facilitates the swinging down of the mesh 10, improving the efficiency of the mesh 10 and the drying operation. The tea leaves on the mesh 10 fall down, achieving the purpose of turning and stirring the tea leaves.

[0027] The structure of the above embodiment can achieve the following benefits. When the mesh 10 is arranged between two symmetrical chains 50, the weight of the limiting seat 30 and the weight block 31 facilitates the swinging down of the mesh 10, improving the efficiency of the mesh 10 and the drying operation.
