Description

Technical Field

[0001] The present invention belongs to the technical field of wire cutting equipment, and more specifically, relates to a wire winding and unwinding device and a wire cutting equipment. Background Art

[0002] Currently, when installing a wire winding wheel, it is necessary to insert the wire winding wheel into the wire winding and unwinding main shaft, then put on a gland, and finally screw in an equal height screw, which is manually tightened with a torque wrench, and the operation is relatively cumbersome; moreover, the clearance between the gland and the shaft hole of the wire winding and unwinding main shaft is only 0.01 - 0.03 mm, which requires a high installation technique for the operator.

[0003] In view of the above problems, the applicant adopted a new installation structure, replacing the gland with a connecting sleeve and a clamp, and driving the clamp to move axially to lock or unlock it with the connecting sleeve to achieve automatic machine installation. However, after implementing this automatic installation method, the applicant found that the wire breakage rate on the wire wheel has increased. To solve this new technical problem, the applicant conducted multiple inspections and detection experiments, and further found that since the assembly area between the wire wheel and the shaft body is exposed to the outside before installation, it is easy to be contaminated with dust particles or other debris in the cutting environment, resulting in the inability to achieve close contact between the clamp and the connecting sleeve, or between the connecting sleeve and the end face of the shaft body, causing deviation in the coaxiality of the wire wheel, and further causing the wire wheel to shake when rotating, ultimately leading to an increase in the wire breakage rate on the wire wheel.

[0004] Therefore, the technical problem to be solved by this application is: how to ensure a high coaxiality in the assembly of the wire wheel. Summary of the Invention

[0005] The object of the present invention is to address the above problems existing in the prior art, and propose a wire winding and unwinding device and a wire cutting equipment, which solve the problem of low coaxiality in the assembly of the wire winding and unwinding device in the prior art. The technical effect of the solution of this application is: to ensure a high coaxiality during the assembly of the wire wheel.

[0006] The object of the present invention can be achieved by the following technical solutions: A wire winding and unwinding device includes a wire wheel; a shaft body, the shaft body is detachably connected to the wire wheel, and the shaft body is provided with a cleaning pipeline through which a cleaning fluid can flow; wherein, a cleaning area is formed between the shaft body and the wire wheel, and a surface to be cleaned is provided in the cleaning area, and the surface to be cleaned communicates with the cleaning pipeline.

[0007] It is understandable that the shaft body is used to drive the wire wheel to rotate, and the rotation of the wire wheel can wind and unwind the cutting wire. The shaft body and the wire wheel are detachably connected and have a cleaning area. The surface to be cleaned in the cleaning area specifically refers to the abutting surface when the shaft body and the wire wheel are assembled, or the abutting surface of other structures between the shaft body and the wire wheel. These abutting surfaces need to be cleaned to ensure close contact. By arranging a cleaning pipeline on the shaft body and communicating with the surface to be cleaned, the dust particles on the surface to be cleaned can be cleaned before the wire wheel and the shaft body are assembled, ensuring high coaxiality between the wire wheel and the shaft body. It should be noted that after the cleaning pipeline cleans the above-mentioned abutting surface, the shaft body and the wire wheel can be assembled and connected. After the assembly is completed, fluid can be introduced again, and the pressure detection unit can detect the pressure difference change of the cleaning pipeline, so as to detect whether there is fluid leakage on the abutting surface. If there is, it is determined that the cleaning is incomplete and needs to be disassembled and cleaned again. If there is no leakage, it means that there is no gap between the abutting surfaces of the wire wheel and the shaft body, meeting the assembly coaxiality requirements.

[0008] In the above-mentioned wire winding and unwinding device, the surface to be cleaned includes the end face of the shaft body close to the wire wheel. The end face of the shaft body is used for assembling and abutting with the wire wheel or the connecting sleeve of the wire wheel. At least one cleaning hole communicating with the cleaning pipeline is arranged on the end face of the shaft body for the cleaning pipeline to clean.

[0009] It is understandable that the end face of the shaft body abuts against the wire wheel or the connecting sleeve of the wire wheel after assembly. Therefore, before assembly, by arranging a cleaning hole communicating with the cleaning pipeline on the end face of the shaft body, fluid is connected for cleaning, and then assembly is carried out, which can ensure high coaxiality between the wire wheel and the shaft body.

[0010] In the above-mentioned wire winding and unwinding device, the surface to be cleaned includes the step surface arranged on the shaft body close to the wire wheel. The step surface can be assembled and abutted with the connecting structure arranged in the cleaning area. At least one cleaning hole communicating with the cleaning pipeline is arranged on the step surface for the cleaning pipeline to clean.

[0011] It is understandable that the connecting structure in the cleaning area is used to connect the shaft body and the wire wheel, and the step surface needs to abut against the connecting structure during assembly. Therefore, cleaning holes communicating with the cleaning pipeline are also arranged to facilitate the introduction of fluid for cleaning.

[0012] In the above-mentioned wire winding and unwinding device, a guiding surface for the shaft body to insert is arranged on the side wall of the wire wheel. A sewage pipeline is formed between the guiding surface and the shaft body to discharge the objects to be cleaned in the cleaning area.

[0013] It is understandable that by arranging a guiding surface on the side wall of the wire wheel, it is convenient for the shaft body to insert into the wire wheel, and the guiding surface is in a flared shape, which can form a sewage pipeline with the shaft body to discharge the cleaned dust particles to the outside.

[0014] In the above-mentioned wire winding and unwinding device, a connecting structure is provided in the cleaning area for disassembling and connecting the shaft body and the wire wheel. The connecting structure includes: a clamp, which is movably connected to the mounting groove provided at the end of the shaft body; a connecting sleeve, which is detachably connected to one end of the wire wheel. Wherein, the clamp and the connecting sleeve have a connected state and a separated state. In the connected state, the clamp and the connecting sleeve can partially abut against each other to form an abutting surface. In the separated state, the abutting surfaces between the clamp and the connecting sleeve are disengaged from each other, and an inner tube is provided between the clamp and the connecting sleeve. One end of the inner tube communicates with the cleaning hole on the step surface, and the other end communicates with the cleaning hole on the abutting surface.

[0015] It can be understood that the clamp and the connecting sleeve are standard components, and can be quickly connected or disengaged by axially moving forward and backward. By arranging the clamp on the mounting groove at the end of the shaft body and the connecting sleeve at the end of the wire wheel, the detachable connection between the shaft body and the wire wheel can be realized. When the clamp and the connecting sleeve are connected, they partially abut against each other to form an abutting surface. When the clamp and the connecting sleeve are in the separated state, fluid can be led to the inner tube through the fluid pipeline and then to the abutting surface for cleaning to ensure the coaxiality between the clamp and the connecting sleeve.

[0016] In the above-mentioned wire winding and unwinding device, it further includes: a fluid docking module, which is arranged opposite to one side of the shaft body, and a fluid docking pipe is further provided on the fluid module for docking with a fluid source; a lifting mechanism, which is arranged below the fluid docking module and can drive the fluid docking module to lift to dock or disengage from the cleaning pipeline.

[0017] It can be understood that the cleaning pipeline on the shaft body needs to introduce or discharge fluid. If the fluid source is manually docked to the cleaning pipeline, the efficiency is low and automation cannot be achieved. Therefore, by setting the fluid docking module, the connection with the fluid source can be maintained, and the cleaning pipeline on the docking shaft body can be docked in a timely manner according to requirements. The lifting mechanism can automatically lift and lower to send the fluid docking module to the area where the shaft body is located for docking, or automatically disengage to retract the fluid docking module. Exemplarily, a valve can also be provided in the fluid docking module to facilitate controlling the opening or closing of fluid delivery.

[0018] In the above-mentioned wire winding and unwinding device, a quick docking structure is provided between the fluid docking module and the shaft body. The quick docking structure includes: an upper quick connector, which is arranged at the fluid inlet on the cleaning pipeline; a lower quick connector, which is arranged at the docking hole of the fluid docking module.

[0019] It can be understood that by setting the upper quick connector and the lower quick connector, the fluid inlet can be quickly aligned and connected with the docking hole. When the shaft body rotates, it can drive the upper quick connector to rotate synchronously. When the cross-sectional projection of the upper quick connector coincides with the cross-sectional projection of the lower quick connector, the alignment is completed, and the docking can be driven by the lifting mechanism.

[0020] In the above-mentioned wire winding and unwinding device, it further includes: a driving device, the driving device is arranged on one side of the end of the shaft body, and the output end of the driving device is connected to the end of the shaft body. The driving device includes a driving motor and an encoder, and the encoder can preset the rotation angle of the driving motor to facilitate the docking of the fluid docking module with the shaft body.

[0021] Exemplarily, the output end of the driving device and the end of the shaft body can be connected by a coupling. When the output end of the driving device rotates, it can drive the shaft body to rotate synchronously. The rotation of the shaft body can drive the wire wheel connected to it to rotate synchronously for wire winding and unwinding. And it can be understood that the driving motor is controlled by the encoder. When the wire wheel and the shaft body need to be reassembled or disassembled, the encoder needs to control the driving motor to rotate a set angle so that the docking hole on the fluid docking module and the cleaning hole on the shaft body are directly opposite.

[0022] In the above-mentioned wire winding and unwinding device, the lifting mechanism is one of a cylinder, an electric cylinder or a hydraulic cylinder.

[0023] In the above-mentioned wire winding and unwinding device, it further includes a detection unit, and the detection unit is used to detect whether there is fluid leakage after the wire wheel and the shaft body are assembled. It should be noted that after the wire wheel and the shaft body are cleaned, the two are assembled into one body, and the surface to be cleaned forms an abutting surface. Whether the abutting surface leaks air can be detected to ensure that the assembly between the wire wheel and the shaft body is not skewed and has high coaxiality.

[0024] In the above-mentioned wire winding and unwinding device, the detection unit is arranged on the sewage discharge pipeline.

[0025] Exemplarily, the detection method can be to continue to introduce fluid into the cleaning pipeline and detect its concentration in the sewage discharge pipeline outside the abutting surface. If the abutting surface is not fully abutted, the concentration of the fluid can be detected to gradually increase. Or, a reactant that can react with the fluid is set at the sewage discharge pipeline, and by detecting the amount of the reactant, it can be indirectly judged whether there is fluid leakage.

[0026] In the above-mentioned wire winding and unwinding device, the detection unit is arranged on the cleaning pipeline, and the detection unit can detect whether there is a continuous increase in fluid in the cleaning pipeline.

[0027] It can be understood that after the wire wheel and the shaft body are assembled, if the abutting surface is fully abutted, the concentration and pressure of the fluid introduced into the cleaning pipeline will continue to increase. A fluid concentration sensing unit or a pressure sensing unit can be used for detection.

[0028] Another object of the present invention is to provide a wire cutting device, comprising: a wire winding and unwinding device as described above; a cutting device, the cutting device comprising a cutting wire which can be arranged on the wire winding and unwinding device.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: by arranging a cleaning pipeline on the shaft body and communicating with the surface to be cleaned, dust particles on the surface to be cleaned can be cleaned before the wire wheel and the shaft body are assembled. After the cleaning is completed and the assembly is carried out, fluid can be introduced into the cleaning pipeline again to detect whether there is leakage at the abutting surface formed after the wire wheel and the shaft body are assembled. According to the detection situation, cleaning can be carried out again or the assembly can be ended, which can ensure that there is no gap at the assembled abutting surface and the wire wheel and the shaft body have high coaxiality; the fluid is led to the inner tube through the fluid pipeline and then to the abutting surface for cleaning to ensure the coaxiality between the clamp and the connecting sleeve; by arranging a sewage pipeline, the cleaned dust particles are discharged out of the cleaning area; by arranging a fluid docking module, the connection with the fluid source can be maintained and the cleaning pipeline on the docking shaft body can be docked in a timely manner according to the needs.

[0046] For the wire winding and unwinding device of this embodiment, please refer to the Figure 1 and Figure 2 in the accompanying drawings of the specification. Specifically, it includes a shaft body 100 and a wire wheel 200. A cleaning pipeline 110 is provided through the shaft body 100 for the entry and exit of cleaning fluid. The wire wheel 200 is detachably connected to the shaft body 100. A cleaning area is formed between the shaft body 100 and the wire wheel 200. There is a surface to be cleaned in the cleaning area, and the surface to be cleaned communicates with the cleaning pipeline 110.

[0047] It can be understood that the shaft body 100 is used to drive the wire wheel 200 to rotate, and the rotation of the wire wheel 200 can perform the operations of winding and unwinding the cutting wire. The shaft body 100 and the wire wheel 200 are detachably connected, and there is a cleaning area. The surface to be cleaned in the cleaning area specifically refers to the surface to be cleaned between the shaft body 100 and the wire wheel 200 or the intermediate connection structure 300. By arranging a cleaning pipeline 110 on the shaft body 100, which is communicated with the surface to be cleaned, dust particles on the surface to be cleaned can be cleaned before the wire wheel 200 and the shaft body 100 are assembled, ensuring that the wire wheel 200 and the shaft body 100 have high coaxiality. And by arranging a sewage pipeline 800, the cleaned dust particles are discharged out of the cleaning area. It should be noted that after the cleaning pipeline 110 cleans the above-mentioned surface to be cleaned, the shaft body 100 and the wire wheel 200 can be assembled and connected. After the assembly is completed, multiple abutting surfaces are formed. Fluid can be introduced again, and the pressure difference change of the cleaning pipeline 110 is detected by the pressure detection unit, so as to detect whether there is a fluid leakage at the abutting surface. If there is, it is determined that the cleaning is incomplete and needs to be disassembled and cleaned again. If there is no leakage, it means that there is no gap at the abutting surface between the wire wheel 200 and the shaft body 100, meeting the assembly coaxiality requirement.

[0048] The surface to be cleaned includes the end face 130 of the shaft body close to the wire wheel 200. Please refer to the Figure 3 and Figure 4 of the attached drawings of the specification. The end face 130 of the shaft body is used to abut against the wire wheel 200 or the connecting sleeve 320 of the wire wheel 200. At least one cleaning hole communicated with the cleaning pipeline 110 is arranged on the end face 130 of the shaft body. It can be understood that the end face 130 of the shaft body abuts against the wire wheel 200 or the connecting sleeve 320 of the wire wheel 200 after assembly. Therefore, before assembly, by arranging a cleaning hole communicated with the cleaning pipeline 110 on the end face 130 of the shaft body, fluid is connected for cleaning, and then assembly is carried out, which can ensure that the wire wheel 200 and the shaft body 100 have high coaxiality.

[0049] The surface to be cleaned includes the step face 140 arranged on the shaft body 100 close to the wire wheel 200. Please continue to refer to the Figure 3 and Figure 4 of the attached drawings of the specification. The step face 140 can abut against the connecting structure 300 arranged in the cleaning area. At least one cleaning hole communicated with the cleaning pipeline 110 is arranged on the step face 140. It can be understood that the connecting structure 300 in the cleaning area is used to connect the shaft body 100 and the wire wheel 200, and the step face 140 needs to abut against the connecting structure 300 on the shaft body 100. Therefore, a cleaning hole is also arranged to be communicated with the cleaning pipeline 110 to facilitate the introduction of fluid for cleaning.

[0050] A guiding surface 201 for inserting the shaft body 100 is arranged on the side wall of the wire wheel 200. Please continue to refer to the Figure 3, a sewage discharge pipeline 800 is formed between the guiding surface 201 and the shaft body 100. It can be understood that by providing the guiding surface 201 on the side wall of the wire reel 200, it is convenient for the shaft body 100 to be inserted into the wire reel 200, and the guiding surface 201 is in a flared shape, which can form a sewage discharge pipeline 800 with the shaft body 100 to discharge the cleaned dust particles to the outside.

[0051] A connecting structure 300 is provided in the cleaning area. Please refer to the Figure 2 , Figure 3 and Figure 9 in the attached drawings of the specification, which is used to disassemble and connect the shaft body 100 and the wire reel 200. The connecting structure 300 includes: a clamp 310, which is movably connected to the mounting groove 120 provided at the end of the shaft body 100; a connecting sleeve 320, which is detachably connected to one end of the wire reel 200; wherein, the clamp 310 and the connecting sleeve 320 have a connected state and a separated state. In the connected state, the clamp 310 and the connecting sleeve 320 can partially abut against each other to form an abutting surface 340. In the separated state, the abutting surface 340 between the clamp 310 and the connecting sleeve 320 is disengaged from each other, and an inner pipe 330 is provided between the clamp 310 and the connecting sleeve 320. One end of the inner pipe 330 communicates with the cleaning hole on the step surface 140, and the other end communicates with the cleaning hole on the abutting surface 340.

[0052] It can be understood that the clamp 310 and the connecting sleeve 320 are configured to achieve quick connection or disconnection by axially moving forward and backward. By arranging the clamp 310 in the mounting groove 120 at the end of the shaft body 100 and the connecting sleeve 320 at the end of the wire reel 200, a detachable connection between the shaft body 100 and the wire reel 200 is realized. When the clamp 310 and the connecting sleeve 320 are connected, they partially abut against each other to form an abutting surface 340. Fluid can be led to the inner pipe 330 through a fluid pipeline and then to the abutting surface 340 for cleaning to ensure the coaxiality between the clamp 310 and the connecting sleeve 320.

[0053] In some embodiments, the winding and unwinding device further includes a fluid docking module 400. Please refer to the Figure 2 , Figure 5 and Figure 8 in the attached drawings of the specification. The fluid docking module 400 is arranged opposite to one side of the shaft body 100, and a fluid docking pipe 420 is further provided on the fluid module for docking a fluid source; a lifting mechanism 500, which is arranged below the fluid docking module 400 and can drive the fluid docking module 400 to lift to dock or disconnect from the cleaning pipeline 110.

[0054] It can be understood that the cleaning pipeline 110 on the shaft body 100 needs to introduce or discharge fluid. If the fluid source is manually docked to the cleaning pipeline 110, the efficiency is low and automation cannot be achieved. Therefore, by setting up the fluid docking module 400, it can maintain connection with the fluid source and dock with the cleaning pipeline 110 on the docking shaft body 100 in a timely manner according to requirements. The lifting mechanism 500 can automatically lift and lower, sending the fluid docking module 400 to the area where the shaft body 100 is located for docking, or automatically disengaging to retract the fluid docking module 400. Exemplarily, a valve can also be provided in the fluid docking module 400 to facilitate controlling the opening or closing of fluid transportation.

[0055] A quick docking structure 600 is provided between the fluid docking module 400 and the shaft body 100. Please refer to the Figure 6 and Figure 7 in the attached drawings of the specification. The quick docking structure 600 specifically includes: an upper quick connector 610, which is arranged on the cleaning hole of the cleaning pipeline 110; a lower quick connector 620, which is arranged on the docking hole 410 of the fluid docking module 400.

[0056] It can be understood that by setting up the upper quick connector 610 and the lower quick connector 620, the fluid inlet 111 can be quickly aligned and connected with the docking hole 410. When the shaft body 100 rotates, it can drive the upper quick connector 610 to rotate synchronously. When the cross-sectional projection of the upper quick connector 610 coincides with the cross-sectional projection of the lower quick connector 620, the alignment is completed, and docking can be driven by the lifting mechanism 500.

[0057] In some embodiments, the wire winding and unwinding device further includes a driving device 700. Please refer to the Figure 1 and Figure 2 in the attached drawings of the specification. The driving device 700 is arranged on one side of the end of the shaft body 100, and the output end of the driving device 700 is connected to the end of the shaft body 100. The driving device 700 includes a driving motor and an encoder, and the encoder can preset the rotation angle of the driving motor to facilitate the docking of the fluid docking module 400 with the shaft body 100.

[0058] Exemplarily, the output end of the driving device 700 and the end of the shaft body 100 can be connected by a coupling. When the output end of the driving device 700 rotates, it can drive the shaft body 100 to rotate synchronously. The rotation of the shaft body 100 can drive the wire wheel 200 connected thereto to rotate synchronously for wire winding and unwinding. And it can be understood that the driving motor is controlled by an encoder. When the wire wheel 200 and the shaft body 100 need to be reassembled or disassembled, the encoder needs to control the driving motor to rotate a set angle so that the docking hole 410 on the fluid docking module 400 is directly opposite to the cleaning hole on the shaft body 100. In some embodiments, the lifting mechanism 500 is one of a cylinder, an electric cylinder or a hydraulic cylinder. Exemplarily, in this embodiment, a cylinder is used for driving the lifting.

[0059] In some embodiments, the wire winding and unwinding device further includes a detection unit (not shown in the figure), and the detection unit is used to detect whether there is fluid leakage after the wire wheel 200 and the shaft body 100 are assembled. It should be noted that after the wire wheel 200 and the shaft body 100 are cleaned, the two are assembled into one body, and the surface to be cleaned forms a butting surface. The airtightness of the butting surface can be detected to ensure that the assembly between the wire wheel and the shaft body is not skewed and has high coaxiality.

[0060] In some embodiments, the detection unit is arranged on the sewage discharge pipeline 800. Exemplarily, the detection means can be to continue to introduce fluid into the cleaning pipeline 110 and detect its concentration in the sewage discharge pipeline 800 outside the butting surface. If the butting surface is not completely butted, the concentration of the fluid can be detected to gradually increase. Or, a reactant that can react with the fluid is arranged at the sewage discharge pipeline 800, and whether there is fluid leakage can be indirectly judged by detecting the amount / change of the reactant, such as color change and shape change.

[0061] In some embodiments, the detection unit is arranged in the cleaning pipeline 110, and the detection unit can detect whether there is continuous increase of fluid in the cleaning pipeline 110. It can be understood that after the wire wheel 200 and the shaft body 100 are assembled, if the butting surface is completely butted, the concentration and pressure of the fluid introduced into the cleaning pipeline 110 will continue to increase, and a fluid concentration sensing unit or a pressure sensing unit can be used for detection.

[0062] When the wire winding and unwinding device of the present invention is specifically applied to a wire cutting device, two groups can be set. One group is for unwinding the cutting wire, and the other group is for winding the cutting wire, which is convenient for distributing the cutting wire on the main cutting roller to form a cutting wire mesh for cutting crystals. Since dust particles are removed after cleaning, it is ensured that the wire winding and unwinding device has high coaxiality. When winding and unwinding the wire, the cutting wire is not easy to be skewed with the wire wheel 200, and the wire breakage rate during winding and unwinding can be significantly reduced.

[0063] Working principle: Please refer to Figure 2 and Figure 3, before detection, the encoder of the driving device 700 controls the driving mechanism to rotate the shaft body 100 to an appropriate angle, so that the cleaning hole on the shaft body 100 is directly opposite to the docking hole 410 on the fluid docking module 400 below, that is, to ensure that the upper docking head is also directly opposite to the lower quick connector 620. At this time, the lifting mechanism 500 below drives the fluid docking module 400 to move upward until the lower quick connector 620 on the fluid docking module 400 is docked with the upper quick connector 610 on the shaft body 100. At this time, fluid can be introduced. Compressed air is taken as an example for the fluid. Since the fluid docking module 400 is always in communication with the fluid source, the control valve can be opened to introduce compressed air into the detection pipeline. When the compressed air flows through the end face 130 or the stepped face 140 or the mating face 340 of the shaft body, the dust particles are driven to the sewage pipeline 800 to discharge the cleaning area. After one cleaning, assembly is carried out. Refer to the Figure 4 , which is the state after the wire wheel and the shaft body are assembled. At this time, fluid is introduced into the cleaning pipeline 110 again. By setting or externally connecting a detection unit (not shown in the figure) on the cleaning pipeline, it is detected whether the abutting surface formed after the wire wheel 200 and the shaft body 100 are assembled leaks. According to the detection situation, cleaning is carried out again or the assembly is ended, which can ensure that the coaxiality between the wire wheel 200 and the shaft body 100 meets the assembly requirements.

[0064] Beneficial effects: By arranging the cleaning pipeline 110 on the shaft body 100 and communicating with the surface to be cleaned, the dust particles on the surface to be cleaned can be cleaned before the wire wheel 200 and the shaft body 100 are assembled. After the cleaning is completed and the assembly is carried out, fluid can be introduced into the cleaning pipeline 110 again to detect whether the abutting surface formed after the wire wheel 200 and the shaft body 100 are assembled leaks. According to the detection situation, cleaning is carried out again or the assembly is ended, which can ensure that there is no gap in the assembled abutting surface, and the wire wheel 200 and the shaft body 100 have high coaxiality; by arranging the sewage pipeline 800, the cleaned dust particles are discharged out of the cleaning area; by arranging cleaning holes on the end face 130 and the stepped face 140 of the shaft body that are communicated with the cleaning pipeline 110, the fluid is connected for cleaning, and then the assembly is carried out after cleaning, which can ensure that the wire wheel 200 and the shaft body 100 have relatively high coaxiality; the fluid is led to the inner tube 330 through the fluid pipeline and then to the mating face 340 for cleaning to ensure the coaxiality between the clamp 310 and the connecting sleeve 320; by arranging the fluid docking module 400, the connection with the fluid source can be maintained and it can be docked with the cleaning pipeline 110 on the docking shaft body 100 as required.
