Description

Technical Field

[0001] The utility model relates to a cooling and temperature reduction mechanism for thermosetting powder coating, belonging to the field of thermosetting powder cooling. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives, which is divided into two categories: thermoplastic powder coating and thermosetting powder coating. Among them, thermosetting powder coating includes epoxy resin, polyester resin and acrylic resin. In the production process of thermosetting powder coating, the main steps are mixing, melting, cooling and crushing. In the prior art, the viscous material extruded from the extruder will fall onto the conveyor belt and then be cooled on the cooling mechanism. The viscous coating will remain on the surface of the conveyor belt. If the conveyor belt is not cleaned in time, the residual coating will be mixed with the newly conveyed coating, which will affect the coating quality. In addition, manual cleaning requires the conveyor belt to be paused before cleaning, which reduces the coating production efficiency. Therefore, it is necessary to design a thermosetting powder coating cooling mechanism that is convenient for cleaning the residual coating on the conveyor belt. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a thermosetting powder coating cooling and temperature reduction mechanism to solve the problems raised in the above-mentioned background technology. The utility model facilitates the cleaning of residual materials on the conveyor belt and reduces the influence of the residual coating on the conveyor belt on the quality of the next cooling coating.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a thermosetting powder coating cooling and cooling mechanism, including a base plate, a protective bin is installed above the base plate, four support frames are evenly installed on both sides of the base plate, a conveyor belt is installed between two of the support frames, the middle part of the conveyor belt is located in the protective bin, a cooling box is installed on the front side of the protective bin, two handles are symmetrically installed on the front side of the cooling box, a conveying port is installed in the middle of the two handles, the bottom of the conveying port is connected and fixed to the cooling box, a motor is installed at one end of the conveyor belt, a cleaning port is opened on one side of the base plate, a storage box is installed at the bottom of the cleaning port, the cooling box is located in the gap in the middle of the conveyor belt, the bottom of the conveyor belt is connected to the cleaning member, the cleaning member is installed on the inner side of the protective bin, and the cooling box is installed with a waterproof layer through a fixing member.

[0005] Furthermore, both ends of the conveyor belt are mounted on a transmission shaft, and a motor is mounted on one end of the transmission shaft.

[0006] Furthermore, the outer side of the waterproof layer is connected to the bottom of the conveyor belt, and the waterproof layer is located between the cooling box and the conveyor belt.

[0007] Furthermore, the fixing part includes a fixing groove, which is opened on the upper surface of the cooling box. Two limit rods are symmetrically installed in the fixing groove. The upper part of the limit rod is connected to the positioning block. One side of the positioning block is installed on the fixing plate, and a pressing column is installed at the bottom of the fixing plate.

[0008] Furthermore, the pressing column and the limiting rod have the same height, and the width of the joint of the fixing plate and the two positioning blocks is the same as the width of the fixing groove.

[0009] Furthermore, the cleaning member includes a positioning base, which is installed on the protective bin through an insert rod, a movable groove is opened above the positioning base, a mounting block is installed inside the movable groove, a scraper is installed on the top of the mounting block, and the top of the scraper is in contact with the conveyor belt.

[0010] Furthermore, a connecting rod is installed at one end of the mounting block located inside the movable groove, a nut is fixedly installed on one side of the movable groove, one end of the connecting rod is threadedly installed in the nut, and a rotating disk is installed at the end of the connecting rod away from the nut, and the rotating disk is located outside the movable groove.

[0011] Furthermore, two positioning rings are symmetrically installed at the bottom of the base plate, the two positioning rings are respectively installed on both sides of the cleaning port, and limiting strips are installed in the two positioning rings, and the two limiting strips are installed on the storage box.

[0012] The beneficial effects of the utility model: the utility model is a thermosetting powder coating cooling and temperature-reducing mechanism, and two limit rods are symmetrically installed on the inner side of the fixed groove. The limit rods limit the position to which the fixed plate can move downward, and the positioning blocks installed on both sides of the fixed plate are made of soft rubber material. The two ends of the waterproof layer are placed flat on the bottom of the fixed groove, and then the fixed plate is inserted into the fixed groove. Because the positioning blocks are made of soft rubber material, they can undergo a certain degree of deformation, thereby limiting the position of the waterproof layer and preventing the waterproof layer from moving when it rubs against the conveyor belt during use.

[0013] The coolant can be poured into the cooling box through the conveying port. Since the coolant temperature is low, it is easy to produce water droplets when it comes into contact with the air and cover the outer surface of the cooling box. Therefore, a waterproof layer is provided on the outside of the cooling box to prevent the bottom of the conveyor belt from rusting due to long-term contact with water droplets.

[0014] The positioning base is connected and fixed to the protective bin by an installing rod, a mounting block is installed at one end of the movable groove, and a scraper is installed on the mounting block. When the scraper is in contact with the conveyor belt for a long time and wears out and cannot clean the residual paint on the surface of the conveyor belt, the rotating disk is rotated to separate the connecting rod and the nut, and then the connecting rod is pulled out of the movable groove to release the restriction on the position of the mounting block, so as to facilitate the replacement of the scraper and improve the cleaning efficiency of the conveyor belt.
