[0033] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0034] Reference Figures 1 to 6 An embodiment of the present invention provides a fully automatic ultra-high pressure screw cleaning machine, including a machine platform 100 and a frame 200. The machine platform 100 is the main body and installation base of the fully automatic ultra-high pressure screw cleaning machine. An installation cavity 101 is formed inside the machine platform 100, and a high-pressure water pump 110 is arranged in the installation cavity 101.

[0035] The frame 200 is connected to the upper end surface of the machine 100. The frame 200 is a frame structure. Square steel pipes can be welded into an outer frame, and then a steel plate is assembled on the outer frame. In order to reduce the propagation of noise, sound insulation cotton is arranged in the inner and outer layers to form a multi-layer sound insulation structure. A cleaning chamber 201 is formed inside the frame 200. A screw rotating mechanism and a cleaning mechanism are arranged in the cleaning chamber 201. The function of the screw rotating mechanism is to drive the screw to be cleaned to rotate. The cleaning mechanism is provided with a high-pressure nozzle 210 and a first power assembly 220. The high-pressure nozzle 210 is connected to the high-pressure water pump 110. The water flow output by the high-pressure water pump 110 enters the high-pressure nozzle 210, and then sprays out from the high-pressure nozzle 210 as a high-pressure water flow, thereby cleaning the screw. The first power assembly 220 is used to drive the high-pressure nozzle 210 to move along the axial direction of the screw to cover the entire screw. When cleaning the screw, the screw is driven to rotate by the screw rotating mechanism, and the high-pressure water flow sprayed by the high-pressure nozzle 210 is sprayed toward the screw to remove the adhesion on the surface of the screw. The first power assembly 220 drives the high-pressure nozzle 210 to move to complete the cleaning of the entire screw, which can efficiently clean the screw and avoid adhesion residue. An openable operating door 300 is set on the front side of the frame 200. The operating door 300 is opened to install the screw on the screw rotating mechanism. The operating door 300 needs to be closed during cleaning to prevent the high-pressure water flow and the adhesion washed out from splashing.

[0036] The operating door 300 is a sandwich structure, and the inner layer and the outer layer can be made of metal plates or plastic plates, wherein the sandwich is sound insulation cotton, and the sound insulation cotton can be waterproof EPDM rubber sound insulation cotton or nitrile rubber sound insulation cotton. A sound insulation seal strip 310 is connected to the edge of the operating door 300, and the sound insulation seal strip 310 covers the edge of the operating door 300. The sound insulation seal strip 310 is provided with an abutment portion 311, and the abutment portion 311 is a hollow structure. When the abutment portion 311 contacts the frame 200, the abutment portion 311 deforms to achieve sealing. Using sound insulation cotton as a sandwich layer can effectively reduce the outward propagation of noise. The sound insulation seal strip 310 is provided at the contact position between the operating door 300 and the frame 200. The abutment portion 311 of the sound insulation seal strip 310 is a hollow structure, and the sealing is achieved by deformation. The sealing effect is good, and the hollow structure can effectively reduce the noise transmission, reduce the operating noise of the fully automatic ultra-high pressure screw cleaning machine, reduce the environmental noise of the workshop, protect the hearing of workers, and meet the requirements of safe production.

[0037] Reference Figure 3In some embodiments of the present invention, the abutment portion 311 is a hollow round tube. When the abutment portion 311 contacts the frame 200, the abutment portion 311 is flattened and deformed to achieve sealing. Of course, the abutment portion 311 can also adopt other shapes, such as 8-shaped, various maze shapes, etc. The abutment portion 311 extends along the length direction of the sound insulation sealing strip 310, and the abutment portion 311 is the same length as or intersects with the sound insulation sealing strip 310, which can meet the requirements of comprehensive sealing, basically eliminate leakage points, and improve the sound insulation effect.

[0038] Reference Figure 3 Considering the need for installation, a side plate 320 is provided at the edge of the operating door 300, and a mounting groove 312 is provided on the sound insulation sealing strip 310. The side plate 320 is inserted into the mounting groove 312, and a plurality of blocking strips 313 are provided on the inner wall of the mounting groove 312. Two blocking strips 313 may be provided on the two inner walls of the mounting groove 312, respectively. The blocking strips 313 abut against the side of the side plate 320, which prevents the sound insulation sealing strip 310 from being separated from the side plate 320 on the one hand, and blocks the sprayed water and sound insulation on the other hand. It can be understood that the blocking strip 313 is inclined in the direction of the abutting portion 311, and when the side plate 320 is separated from the mounting groove 312, the blocking strip 313 provides resistance to prevent it from being separated.

[0039] In some embodiments of the present invention, the operating door 300 is connected to a driving member 350, and the driving member 350 drives the operating door 300 to rise and fall to open and close. Figure 6 As shown, the driving member 350 is a cylinder, the frame 200 is provided with an optical axis, the operating door 300 is connected to the optical axis in an arc, and the operating door 300 is driven by the cylinder to rise and fall. In addition, the driving member 350 can also use other structures, such as an electric push rod, a gear rack combination, etc.
