Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to an extruder with cooling function for powder coating processing. Background Technology

[0002] Powder coating refers to a new type of solvent-free solid powder coating. It is made by mixing, crushing, and sieving film-forming resins, additives, pigments, fillers, etc. The coating application requires electrostatic spraying and baking to form a film. It has the characteristics of being solvent-free, pollution-free, recyclable, environmentally friendly, energy-saving and resource-saving, reducing labor intensity and high mechanical strength of the coating film. Powder coating is a completely different form from ordinary coatings. It exists in the state of fine powder. Because no solvent is used, it is called powder coating. Powder coating is widely used because of its harmless, high-efficiency, resource-saving and environmentally friendly characteristics.

[0003] According to the search (application number: 202022334352.4), an extruder with cooling function for powder coating processing is disclosed, which includes a base, a U-shaped bracket fixedly provided at the top of the base, an extrusion cylinder fixedly provided through the top of the U-shaped bracket, the upper part of the extrusion cylinder being located above the U-shaped bracket and fixedly fitted with a limiting plate, the bottom end of the limiting plate abutting against the top of the U-shaped bracket, and a bearing seat fixedly embedded through the top of the extrusion cylinder.

[0004] In the process of realizing this utility model, the inventors discovered that the following problems in the prior art have not been solved: Although the device has a good cooling effect, it adopts a built-in water cooling method, which relies on heat conduction for cooling, and the cooling effect is not ideal and urgently needs to be improved. Therefore, we propose an extruder with cooling function for powder coating processing. Utility Model Content

[0005] The purpose of this invention is to provide an extruder with a cooling function for powder coating processing, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an extruder with cooling function for powder coating processing, comprising a gantry frame, wherein a material cylinder is fixedly inserted through the middle of the top wall of the gantry frame, and a box body is fixedly installed on one side of the gantry frame;

[0007] A motor is fixedly installed at the top center of the material cylinder, a feeding screw is fixedly installed at the bottom of the motor's drive shaft, an extrusion port is provided at the bottom end of the material cylinder, and a feeding hopper is connected to one side of the top of the material cylinder.

[0008] Air duct b and air duct a are respectively placed on the top of the feed hopper and directly below the extrusion port. Air duct a and air duct b are respectively fixedly connected to the gantry frame and the material cylinder by brackets.

[0009] Both air duct a and air duct b have an inner cavity. The inner side of the inner cavity is connected to several sets of uniformly arrayed openings. A filter screen is fixedly installed in the opening. An exhaust fan is connected to one side of both air duct a and air duct b. An air outlet pipe is connected to one side of the exhaust fan.

During the use of the extruder, the exhaust fan can draw in and exhaust air, and the air is drawn in through the vent. The filter screen blocks materials or impurities, which can achieve air cooling. The two sets of air ducts are respectively set at the feeding end and the discharging end, so both feeding and discharging can be air cooled.

The distance sensor a and the alarm can be used together to detect the distance between themselves and the external object. When the distance detected by the distance sensor a for a set time is greater than the set threshold, it means that a single feeding is completed.

The two sets of air ducts are respectively set at the feeding end and the discharging end, so both feeding and discharging can be air cooled. Compared with the existing built-in type, the cooling function is more ideal.

[0017] 2. This utility model discloses an extruder with cooling function for powder coating processing. By setting a distance sensor and an alarm, the distance between the extruder and the external object can be detected by distance sensor a and distance sensor b respectively. When the distance detected by distance sensor a for a set time is greater than a set threshold, it means that a single feeding is completed. When the distance detected by distance sensor b for a set time is greater than a set threshold, it means that a single batch of material is extruded.

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1-3 This utility model provides a technical solution: an extruder with cooling function for powder coating processing, including a gantry frame 1. Positioning blocks are fixedly installed at the bottom ends of both legs of the gantry frame 1, and positioning holes are provided at the four corners of the positioning blocks. Positioning bolts can be moved through the positioning holes of the positioning blocks and screwed onto a pre-set threaded structure on the support, realizing the detachable and stable positioning of the extruder. A material cylinder 4 is fixedly inserted through the middle of the top wall of the gantry frame 1, and a box body 3 is fixedly installed on one side of the gantry frame 1. A motor 41 is fixedly installed at the middle of the top of the material cylinder 4, and a feeding screw 42 is fixedly installed at the bottom of the drive shaft of the motor 41. An extrusion port 43 is provided at the bottom of the material cylinder 4, and a feed hopper 44 is connected to the top side of the material cylinder 4. Air ducts b21 and a2 are respectively placed on the top of the feed hopper 44 and directly below the extrusion port 43. Air ducts a2 and b21 are respectively connected to supports. The gantry frame 1 and the material cylinder 4 are fixedly connected; the air ducts a2 and b21 are both provided with an inner cavity 5, and the inner side of the inner cavity 5 is connected to several sets of uniformly arrayed openings 51. The openings 51 are fixedly installed with filters 52. The air ducts a2 and b21 are both connected to an exhaust fan 23 on one side, and the exhaust fan 23 is connected to an air outlet pipe 24 on one side; the housing 3 is fixedly installed with a processor 31 and an alarm 32. The opening of the housing 3 is fixedly installed with a dustproof net, and the side wall of the housing 3 is connected with a conduit 33. The dustproof net can block external dust, and the conduit 33 provides wires for connecting the internal and external components. The side of the gantry frame 1 facing away from the housing 3 is fixedly installed with an indicator sign 11, and the indicator sign 11 is fixed by welding. The indicator sign 11 can inform the operator of the corresponding procedures, making it easy to understand and use, and can also inform the operator of safety precautions.

[0025] In this technical solution, components such as air duct a2, air duct b21, and exhaust fan 23 can be used together. During the use of the extruder, the exhaust fan 23 can draw in and exhaust air, and the inlet 51 can also be used for air extraction. The filter screen 52 can block materials or impurities, thus achieving air cooling. The two sets of air ducts are respectively set at the feeding end and the discharging end, so both feeding and discharging can be air cooled. Compared with the existing built-in type, the cooling effect is more ideal.

[0026] In some technical solutions, a distance sensor b22 is fixedly installed on one side of the top of the air duct b21 by a bracket, and a distance sensor a12 is fixedly installed on the side of the gantry 1 near the air duct a2 by a bracket. The data output terminals of the distance sensor a12 and the distance sensor b22 are both connected to the data input terminal of the processor 31. The signal output terminal of the processor 31 is connected to the signal input terminals of the exhaust fan 23 and the alarm 32, respectively.

[0027] In this technical solution, components such as a distance sensor and an alarm 32 can be used together. The distance between the distance sensor a12 and the external object can be detected by the distance sensor a12 and the distance sensor b22 respectively. When the distance detected by the distance sensor a12 for a set time is greater than the set threshold, it means that the feeding of material is completed. When the distance detected by the distance sensor b22 for a set time is greater than the set threshold, it means that the extrusion of material in a batch is completed. The processor 31 issues an instruction to shut down the corresponding exhaust fan 23, which can achieve automatic shutdown and avoid unnecessary power consumption. At the same time, when the distance detected by the sensor b is greater than the set threshold, the alarm 32 is activated to remind personnel to replenish the material in time.

[0028] Working principle: It should be noted that this utility model is an extruder with cooling function for powder coating processing. All parts are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0029] When using an extruder with a cooling function for powder coating processing, the extruder is placed at the powder coating processing station, and then the extruder is connected to an external power source. During this process, material can be added through the feed hopper 44, and the feeding screw 42 is rotated by the motor 41 and then discharged from the extrusion port 43 for powder coating processing.

[0030] By incorporating air ducts a2 and b21 and an exhaust fan 23, the extruder can draw in and exhaust air during operation. This, combined with the exhaust port 51, allows for air extraction. A filter screen 52 blocks materials and impurities, achieving effective air cooling. With two sets of air ducts positioned at the feeding and discharging ends respectively, both feeding and discharging processes can be air-cooled. Compared to existing built-in systems, this provides a more ideal cooling effect. Equipped with distance sensors a12 and b22, the distance between the extruder and external objects is detected. When the distance detected by distance sensor a12 for a set time exceeds a set threshold, a single feeding operation is complete. When the distance detected by distance sensor b22 for a set time exceeds a set threshold, a single batch of material is extruded. The processor 31 then issues a command to shut down the corresponding exhaust fan 23, achieving automatic shutdown and avoiding unnecessary energy consumption. Simultaneously, when sensor b detects a distance exceeding a set threshold, the alarm 32 activates, reminding personnel to replenish material promptly.
