Description

Technical Field

[0001] The utility model relates to a cooling device, in particular to a cooling device at the end of a plant straw drainage board production line, belonging to the technical field of drainage board processing. Background Art

[0002] In the invention patent with Chinese patent application number: 201910688340.0, a plant straw drainage board production device is disclosed, and the technical structure and process steps of the production device assembly line are specifically disclosed. During production, plant straw and other materials are mixed in the mixing barrel, further mixed and heated through the feeding conduit, and fall into the conveyor belt after preliminary dispersion in the material distribution chamber. The diversion mechanism spreads all the materials evenly, and then the upper and lower guide rollers are pressed to obtain a wide drainage board, which is then cut into a finished plant straw drainage board. The assembly line has the advantages of advanced technology. However, it was found in production practice that in the traction process from the upper and lower guide rollers to the cutting mechanism, the drainage board has low tensile strength and poor toughness, which seriously affects the production efficiency. The reason was found that the drainage board still has a process temperature of about 120° in the above-mentioned flowing water, which greatly reduces the toughness of the drainage board traction process, resulting in reduced production efficiency. Summary of the invention

[0003] In view of the technical deficiencies in the invention patent referred to in the background technology, the utility model provides a cooling device at the end of a plant straw drainage board production line, through which the stability of the plant straw drainage board production line is further improved and the production efficiency is further improved.

[0004] The utility model is implemented by the following technical scheme: a cooling device at the end of a plant straw drainage board production line, comprising: a drainage board, a frame, an upper guide roller, a lower guide roller, an upper pressure roller, a lower support roller, a spiral feeding mechanism, a water tank and a cutting mechanism. The plant blank of the drainage board is rolled and formed by the upper guide roller and the lower guide roller and then pulled out to the cutting mechanism, and is characterized in that:

[0005] The upper pressure roller and the lower support roller are rotating bodies with axes parallel to each other, and both ends thereof are horizontally arranged on the frame through support seats, and are located in the path where the drainage plate is pulled out from between the upper guide roller and the lower guide roller to the cutting mechanism, and the upper pressure roller is arranged below and in front of the lower support roller;

[0006] The screw feeding mechanism is divided into two groups, which are respectively placed at the two ends of the upper pressure roller, and each group is composed of a screw, a screw nut and a guide rail. The screw nut and the guide rail are fixed on the frame, and the screw is screwed into the screw nut to form a screw pair. The support seat is placed in the guide rail to form a moving pair. The screw axis is perpendicular to the axis of the upper pressure roller, and the lower end of the screw is movably connected to the support seats at the two ends of the upper pressure roller. The screws at the two ends are rotated to make the two support seats drive the upper pressure roller to move up and down horizontally.

[0007] The water tank is arranged below the upper pressing roller, and cooling water is arranged in the tank, and the outer circumferential surface of the upper pressing roller is immersed in the cooling water;

[0008] The drainage plate flows out between the upper guide roller and the lower guide roller, and its upper plate surface bypasses the outer cylindrical surface of the upper pressure roller and is pressed and immersed in the water tank for cooling, and then the lower plate surface flows from the outer cylindrical surface of the lower roller to the cutting mechanism.

[0009] In some embodiments, the lower end of the screw rod is in contact with the support seats at both ends of the upper pressure roller. The screw rods at both ends are rotated clockwise so that the support seats drive the upper pressure roller to move downward horizontally. The screw rods at both ends are rotated clockwise so that the support seats are disengaged from the lower end of the screw rod. The upper pressure roller moves up and down horizontally under the action of external force.

[0010] Furthermore, rolling bearings are provided at both ends of the upper pressure roller, and the rolling bearings are arranged in the support seat.

[0011] The utility model arranges a cooling device at the end of the assembly line of the original plant straw drainage board production device, which effectively reduces the temperature of the drainage board formed during the manufacturing process, thereby greatly enhancing the traction strength and toughness of the drainage board and improving production efficiency.

[0012] The utility model has the advantages of reasonable design, simple structure, good process effect and high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The utility model is further explained below in conjunction with the accompanying drawings:

[0017] As attached Figure 1 , 2 As shown, the upper pressure roller 3 and the lower support roller 4 are rotating bodies with axes parallel to each other, and their two ends are horizontally arranged on the frame 1 through rolling bearings and support seats 503 respectively, and are located in the path where the drainage plate 1 is pulled out from between the upper guide roller 2 and the lower guide roller 7 to the cutting mechanism (not shown in the figure), and the upper pressure roller 3 is arranged in the lower front of the lower support roller 4; the spiral feeding mechanism 5 is divided into two groups, which are respectively placed at the two ends of the upper pressure roller 3, and each group is composed of a screw rod 501, a screw rod nut 502 and a guide rail 504, the screw rod nut 502 and the guide rail 504 are fixed on the frame, the screw rod 501 is screwed into the screw rod nut 502 to form a spiral pair, the support seat 503 is placed in the guide rail 504 to form a moving pair, and the screw rod 501 The axis of the upper pressure roller 3 is perpendicular to the axis of the upper pressure roller 3, and its lower end is connected to the support seats 503 at both ends of the upper pressure roller 3. The screw rods 501 at both ends are rotated to make the support seats 503 drive the upper pressure roller 3 to move up and down horizontally; the lower end of the screw rod 501 can also contact the support seats 503 at both ends of the upper pressure roller 3, and the screw rods 501 at both ends are rotated clockwise to make the support seats 503 drive the upper pressure roller 3 to move downward horizontally, and the screw rods 501 at both ends are rotated counterclockwise to disengage the support seats 503 from the lower ends of the screw rods 501, and the upper pressure roller 3 can move up and down horizontally under the action of manual external force; the water tank 6 is arranged below the upper pressure roller 3, and cooling water is provided in the tank, and the outer cylindrical surface of the upper pressure roller 3 is immersed in the cooling water.

[0018] During operation, the drain plate 1 flows out from between the upper guide roller 2 and the lower guide roller 3, and bypasses from the bottom of the upper pressure roller 3. The screw rod 501 is rotated to push the lower end of the support seat 503, and drive the upper pressure roller 3 to move downward horizontally, so that the upper plate surface of the drain plate 1 is close to the outer cylindrical surface of the upper pressure roller 3, and at the same time, the drain plate 1 is pressed into the water tank 6 for cooling.
