Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and in particular to a conveyor belt device with a cooling function. Background Art

[0002] Conveyor belts are commonly used in a variety of commercial and industrial applications. For the purpose of transporting products and materials, conveyor belts in the prior art have many functions. There are conveyor belts with cooling functions, which are used to cool materials on the conveyor belt to facilitate subsequent processing or packaging; however, the existing conveyor belts with cooling functions have a relatively simple structure and only use a simple fan for heat dissipation and cooling. This heat dissipation and cooling method is relatively simple and the heat dissipation and cooling effect is insufficient. If it is necessary to improve the cooling effect of the materials on the conveyor belt, it is necessary to reduce the conveying rate of the conveyor belt and increase the residence time of the materials on the conveyor belt. However, this cooling and heat dissipation method affects the transmission efficiency. Therefore, there is no conveyor belt that can improve the cooling and heat dissipation effect of the materials and the transmission efficiency.

[0016] A further improvement is that a main servo motor is installed on the support leg, and the main servo motor is connected to the driving shaft of the first driving gear and the rotating shafts on the upper cooling water bag and the lower cooling water bag through two sets of belts, so as to drive the first conveyor belt body, the upper cooling water bag and the lower cooling water bag to rotate synchronously, and the second driving gear is driven by a second servo motor.

The bottom of the second threaded rod passes through the lower leg and is threadedly assembled with the lower leg. The height of the telescopic leg is adjusted by rotating the second threaded rod.

[0018] The beneficial effects of the present invention are as follows: the conveyor belt device with cooling function is composed of a first conveyor belt body on a main frame and a second conveyor belt body on a sub-frame, the bottom of the feed hopper on the main frame is set to an open rectangular design with the same width as the first conveyor belt body, and is provided with a pull-out plate, the amount of material discharged can be controlled by controlling the position of the pull-out plate, so as to achieve the purpose of laying the material flat on the first conveyor belt body, and the setting of the height control scraper assembly can make the cooling material per unit area on the first conveyor belt body evenly laid with uniform thickness, thereby improving the heat dissipation and cooling uniformity of the material;

Different from the traditional fan heat dissipation method, the preliminary blowing assembly adopts the assembly mode of long-strip shutter adjustment openings. The blowing angle can be adjusted through the shutter adjustment openings on both sides, and the blowing area and range of the material to be cooled can be selectively adjusted. With the assistance of the bottom structure of the feed hopper and the scraper assembly, the cooling and heat dissipation of the material can be more effectively performed.

[0020] Because of the heat transfer and the thermal conductivity of the metal material of the aluminum alloy strip, when working for a long time, part of the heat of the material will also be transferred to the aluminum alloy strip. When the aluminum alloy strip at the same position passes through the next round of material transportation, because of the previous round or several rounds of transportation, its own temperature will also be higher than the initial working temperature, and it will carry a certain amount of heat. At this time, the heat dissipation and cooling effect of the material will be reduced during operation. In the structure of the present application, a conveyor belt cooling component is provided. The conveyor belt cooling component is composed of an upper cooling water bag and a lower cooling water bag. Cooling water or coolant is filled inside the upper cooling water bag and the lower cooling water bag, and it is an annular structure, which rotates synchronously with the first conveyor belt body in contact, and is used to cool the aluminum alloy strip on the first conveyor belt body, providing an initial temperature difference for material cooling, which is more conducive to the heat dissipation and cooling of the material;

[0021] A transfer cooling assembly is installed on the sub-frame. The transfer cooling assembly is composed of a stainless steel cooling box and an assembly T-frame. The interior of the stainless steel cooling box is a hollow structure filled with cooling water for cooling. When the material falls from the first conveyor belt body to the stainless steel cooling box, it can be partially cooled by contacting the upper surface of the stainless steel cooling box. At the same time, due to the inclination setting of the stainless steel cooling box, when the material passes through the stainless steel cooling box and then flips and falls onto the second conveyor belt body, the material may change from the original bottom contacting the first conveyor belt body to the upper part of the material contacting the second conveyor belt body, or the side contacting the second conveyor belt body. The arrangement mode has been changed, which is more conducive to the uniformity of heat dissipation of various parts of the monomer material.

[0022] The sub-frame is also provided with an evaporative cooling mechanism, which is composed of an evaporative wet curtain, a cooling fan, a water storage box, a water pump, a nozzle and a cooling air supply cavity. The evaporative wet curtain is moistened by supplying water to the evaporative wet curtain. When the external hot air passes through the evaporative wet curtain, due to the principle of water absorbing heat and evaporating, a part of the heat of the external air is taken away, which can reduce the temperature of the external hot air by about 5-8°C and blow it out as cold air. The material on the second cooling belt body is evenly cooled through the cooling air supply cavity in the final step of heat dissipation.

[0023] Furthermore, a debris screening mechanism is provided at the bottom of the main frame, the auxiliary frame and the stainless steel cooling box. A debris collecting box is slidably installed on the main frame and the auxiliary frame, and is used to collect the debris of the material screened out in cooperation with the holes on the aluminum alloy belt plate. A middle collecting box is provided at the bottom of the stainless steel cooling box. The upper vertical section of the middle collecting box is a concave-convex structure. The concave area is provided with a middle collecting hole to assist the overall device in collecting the debris. The convex area is used to prevent most of the debris from falling onto the second conveyor belt body. A pull-out box is provided at the bottom of the middle collecting box to pour out the collected debris. The overall collection of debris is also structurally and functionally strong.

[0024] The conveyor belt device with cooling function is provided with six groups of different structures, but the functions are the same, that is, the structure is convenient for heat dissipation and cooling of materials. The structure has strong innovation and practicality. Without affecting the material transmission efficiency, the cooling effect of the material is greatly improved, which is different from the existing conveyor belt device with cooling function to a large extent.

[0054] Because of the heat transfer and the thermal conductivity of the metal material of the aluminum alloy strip 14, when working for a long time, part of the heat of the material will also be transferred to the aluminum alloy strip 14.

At the same time, due to the inclination setting of the stainless steel cooling box 31, when the material passes through the stainless steel cooling box 31 and then flips and falls onto the second conveyor belt body 12, the material may change from the original bottom contacting the first conveyor belt body 9 to the upper part of the material contacting the second conveyor belt body 12, or the side contacting the second conveyor belt body 12.

The material on the second cooling belt body 12 is evenly cooled through the cooling air supply cavity 46 in the last step of heat dissipation cooling.

[0057] Furthermore, a debris screening mechanism is provided at the bottom of the main frame 1, the auxiliary frame 2 and the stainless steel cooling box 31.
