Description

Technical Field

[0001] This invention relates to the field of material discharge equipment technology, and in particular to an automatic cleaning system and method for the pressure plate of a material discharge machine. Background Technology

[0002] Adhesive-making equipment is a key piece of equipment widely used in the chemical industry to achieve mixing, reaction, dissolution, and dispersion of solid-liquid or liquid-liquid phase materials. Among them, the discharge machine of adhesive-making equipment uses a pressure plate to pressurize and transport high-viscosity materials from the bottom outlet of the material tank to the pipeline, thereby realizing the discharge of high-viscosity materials.

[0003] In existing technologies, the cleaning of the discharge machine's pressure plate is done manually. After the discharge operation is completed, operators need to clean the residual material on the surface of the pressure plate. However, with the increasing automation of adhesive production equipment, the compatibility of manual on-site cleaning operations with the overall automated production process is gradually decreasing, making it difficult to improve production efficiency. At the same time, during manual cleaning, operators will come into contact with hazardous chemical materials and cleaning solutions, posing safety hazards. Summary of the Invention

[0004] Therefore, it is necessary to provide an automatic cleaning system and method for the discharge machine pressure plate, which addresses the problems of low production efficiency due to low compatibility with the overall automated production process of the glue-making equipment and the safety hazards in the cleaning process caused by relying on manual cleaning of the discharge machine pressure plate.

[0005] The technical solution adopted in this invention is as follows: An automatic cleaning system for a discharge machine pressure plate includes a rotating mechanism installed on the discharge machine, wherein the rotating mechanism is correspondingly engaged with the pressure plate to drive the pressure plate to rotate; And a cleaning hood installed on the discharge machine, the cleaning hood having a spray nozzle corresponding to the pressure plate, the spray nozzle being connected to the outlet of the storage tank, the storage tank containing cleaning liquid; When the discharge machine is in automatic cleaning mode, the rotating mechanism drives the pressure plate to rotate, and the liquid storage tank sprays cleaning liquid onto the pressure plate through the spray nozzle.

[0006] As a further improvement to the above technical solution: The spray nozzle is connected to the outlet of the storage tank via a spray pipe assembly.

[0007] A liquid supply pump is installed on the spray pipe assembly.

[0008] The cleaning hood is equipped with a drying vent, and a fan is installed at the drying vent.

[0009] A waste liquid recovery mechanism is arranged below the cleaning hood to recover the waste liquid after cleaning.

[0010] The structure of the waste liquid recycling mechanism is as follows: it includes a first waste liquid tank arranged directly below the cleaning hood. The outlet of the first waste liquid tank is connected to the inlet of the second waste liquid tank through a first pipe assembly. A recycling pump is installed on the first pipe assembly. The waste liquid after cleaning is collected through the first waste liquid tank. Under the action of the recycling pump, the waste liquid in the first waste liquid tank flows into the second waste liquid tank through the first pipe assembly.

[0011] The outlet of the second waste liquid tank is connected to the inlet of the storage tank through a second pipe assembly. A filter is installed on the second pipe assembly, and the filter integrates a particle detection device for detecting the residual material in the waste liquid.

[0012] The rotating mechanism has the following structure: it includes a rotary drive component installed inside the discharge machine, the output end of the rotary drive component is connected to a gear shaft, and the gear shaft is meshed with a gear assembly set on the top wall of the pressure plate. The rotary drive unit drives the gear shaft to rotate, thereby driving the pressure plate to rotate through the gear assembly.

[0013] A cleaning method using the above-mentioned automatic cleaning system for the discharge machine pressure plate includes the following steps: Step 1: The pressure plate moves downward in a vertical line, and at the same time, the rotating mechanism moves downward in a vertical line along with the pressure plate until the pressure plate moves to the bottom of the storage container, thereby completing the discharge of the material inside the storage container; Step 2: After the material is discharged, the pressure plate moves upward in a vertical direction. At the same time, the rotating mechanism moves upward in a vertical direction along with the pressure plate until the pressure plate rises to the target position, and then the cleaning begins. Step 3: During cleaning, the rotating mechanism drives the pressure plate to rotate, and at the same time, the cleaning fluid in the storage tank is sprayed onto the pressure plate through the spray nozzle, thereby cleaning the pressure plate.

[0014] As a further improvement to the above technical solution: The discharge machine is equipped with a proximity switch assembly, which detects the stroke of the pressure plate.

[0015] The beneficial effects of this invention are as follows: This invention features a compact and reasonable structure and is easy to operate. By setting up a rotating mechanism, a liquid storage tank, and a cleaning hood, it can automatically clean the pressure plate after the pressure plate has finished discharging the material, realizing full automation of the equipment process and effectively improving production efficiency. At the same time, the automated cleaning process can avoid operators coming into contact with hazardous chemical materials and cleaning liquids, effectively improving the working environment and reducing the requirements for site and personnel.

[0016] The present invention also has the following advantages: (1) In this invention, by setting up an air drying port and a fan, the pressure plate can be dried after cleaning, so as to achieve rapid drying of the pressure plate surface.

[0017] (2) By setting up a waste liquid recycling mechanism, the waste liquid after cleaning can be collected in a timely manner, avoiding the waste liquid from flowing around and polluting the production environment; at the same time, it is convenient to centrally treat the waste liquid to realize resource recycling and reuse, and reduce production costs.

[0018] (3) In this invention, by setting up a filter with an integrated particle detection device, the residual material in the waste liquid can be detected while filtering the waste liquid. The detection result determines whether the cleaning of the pressure plate is completed, thereby realizing intelligent and precise control of the cleaning process.

[0019] (4) By setting a rotating mechanism, the pressure plate can be rotated during the cleaning process, thereby ensuring that the outer surface of the pressure plate is thoroughly cleaned.

[0020] (5) The cleaning method of the present invention can realize automated cleaning of the discharge machine pressure plate, remote control detection, reduce manual intervention, and achieve efficient cleaning; at the same time, the cleaning effect is good, and the pressure plate can be thoroughly cleaned to avoid contamination of the next batch of materials to be discharged.

[0026] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0027] like Figures 1-3As shown, this embodiment of an automatic cleaning system for a discharge machine pressure plate includes a rotating mechanism 3 installed on a discharge machine 1. The rotating mechanism 3 corresponds to and cooperates with the pressure plate 2 to drive the pressure plate 2 to rotate. In this embodiment, the discharge machine 1 is used to discharge high-viscosity materials. The pressure plate 2 is installed on the discharge machine 1, and the material is discharged by pressing it down vertically. A cleaning hood 5 is also installed on the discharge machine 1. The cleaning hood 5 has spray nozzles 6 corresponding to the pressure plate 2. The spray nozzles 6 are inclined on the outer wall of the cleaning hood 5 and connected to the outlet of a storage tank 4 containing cleaning fluid. When the discharge machine 1 is in automatic cleaning mode, the rotating mechanism 3 drives the pressure plate 2 to rotate, and the storage tank 4 sprays cleaning fluid onto the pressure plate 2 through the spray nozzles 6. This automatic cleaning system for the discharge machine pressure plate can achieve automated cleaning of residual material on the pressure plate, reducing manual labor, thereby improving production efficiency, reducing labor costs, reducing the health hazards of cleaning fluid and residual material to operators, and reducing production safety risks.

[0028] Spray nozzle 6 is connected to the outlet of liquid storage tank 4 via spray pipe assembly 10, and a liquid supply pump 8 is installed on spray pipe assembly 10. By setting up liquid supply pump 8, power is provided for the delivery of cleaning liquid, ensuring that it flows stably and continuously from liquid storage tank 4 through spray pipe assembly 10 to spray nozzle 6, ensuring spraying effect, and making pressure plate 2 fully and evenly cleaned.

[0029] The cleaning hood 5 is equipped with a drying vent 7, and a fan is installed at the drying vent 7. By setting up the drying vent 7 and the fan, the pressure plate 2 can be dried after cleaning, so as to achieve rapid drying of the surface of the pressure plate 2.

[0030] A waste liquid recovery mechanism 9 is arranged below the cleaning hood 5 to recover the waste liquid after cleaning. By setting up the waste liquid recovery mechanism 9, the waste liquid after cleaning can be collected in a timely manner, avoiding the waste liquid from flowing around and polluting the production environment; at the same time, it is convenient to centrally treat the waste liquid to achieve resource recycling and reuse, thereby reducing production costs.

[0031] The waste liquid recovery mechanism 9 has the following structure: it includes a first waste liquid tank 901 located directly below the cleaning hood 5. The outlet of the first waste liquid tank 901 is connected to the inlet of the second waste liquid tank 902 via a first pipe assembly 904. A recovery pump 903 is installed on the first pipe assembly 904. The waste liquid after cleaning is collected through the first waste liquid tank 901. Under the action of the recovery pump 903, the waste liquid in the first waste liquid tank 901 flows into the second waste liquid tank 902 through the first pipe assembly 904. In this embodiment, the first waste liquid tank 901 can be a storage container for discharging materials or other types of storage tanks. During cleaning, the cleaning hood 5 covers the top of the first waste liquid tank 901 and seals it, thereby forming a closed cleaning space between the cleaning hood 5 and the first waste liquid tank 901, preventing the cleaning liquid from splashing during the spraying process.

[0032] In this embodiment, the outlet of the first waste liquid tank 901 is located in the center of the bottom wall of the first waste liquid tank 901, which can prevent liquid from accumulating inside the first waste liquid tank 901.

[0033] The outlet of the second waste liquid tank 902 is connected to the inlet of the storage tank 4 via a second pipe assembly 905. A filter is installed on the second pipe assembly 905, and the filter integrates a particle detection device for detecting the residual material in the waste liquid. The waste liquid in the second waste liquid tank 902 flows into the storage tank 4 through the second pipe assembly 905 and is filtered by the filter. In this embodiment, the filter integrates a particle detection device, which can detect the residual material in the waste liquid. The detection result determines whether the cleaning of the pressure plate 2 is complete, realizing intelligent and precise control of the cleaning process.

[0034] In this embodiment, the recovery pump 903 is used to provide drive so that the waste liquid in the first waste liquid tank 901 can flow into the second waste liquid tank 902 through the first pipe group 904, and the waste liquid in the second waste liquid tank 902 can flow into the storage tank 4 through the second pipe group 905.

[0035] The rotating mechanism 3 has the following structure: it includes a rotary drive 301 installed inside the discharge machine 1. The output end of the rotary drive 301 is connected to a gear shaft 302, and the gear shaft 302 is meshed with a gear assembly 303 disposed on the top wall of the pressure plate 2. The rotary drive 301 drives the gear shaft 302 to rotate, thereby driving the pressure plate 2 to rotate through the gear assembly 303. By setting the rotating mechanism 3, the pressure plate 2 can be rotated during the cleaning process, thus ensuring that the outer surface of the pressure plate 2 is thoroughly cleaned.

[0036] In this embodiment, the outer circular surface of the gear shaft 302 is provided with a number of first gear teeth along the circumference, and the gear assembly 303 includes a number of second gear teeth 303 provided along the circumference. The first gear teeth and the second gear teeth form a bevel gear transmission structure.

[0037] In this embodiment, the rotary drive 301 can be a servo motor, which is fixed on the guide column 304. The guide column 304 is installed on the frame of the discharge machine 1. One end of the guide column 304 is connected to the output end of the linear drive (which can be a cylinder). The linear drive drives the guide column 304 to move vertically upward or downward relative to the frame, so that the rotary drive 301 can move up and down with the lifting and lowering movement of the pressure plate 2, thereby ensuring that the gear shaft 302 can always mesh with the gear tooth assembly 303 on the pressure plate 2.

[0038] In this embodiment, the spray pipe assembly 10, the first pipe assembly 904, and the second pipe assembly 905 can all be formed by splicing several short pipes or by using long pipes, depending on the specific usage and installation requirements. In addition, each pipe is equipped with a corresponding control valve assembly, which is configured according to the actual production requirements.

[0039] like Figure 4 As shown, this embodiment also provides a cleaning method using the above-mentioned automatic cleaning system for the discharge machine pressure plate, including the following steps: In this embodiment, the discharge machine 1 is equipped with a proximity switch assembly, which includes an upper limit proximity switch and a lower limit proximity switch. The stroke of the pressure plate 2 is detected by the proximity switch assembly. In addition, in this embodiment, the discharge machine 1 is equipped with an industrial control computer and a cleaning button. When the cleaning button is pressed, the industrial control computer controls the automatic cleaning system of the discharge machine pressure plate in this embodiment to automatically clean the pressure plate 2. In this embodiment, the liquid supply pump 8, the rotary drive component 301, the recovery pump 903, and the fan are all electrically connected to the industrial control computer and work according to the control commands sent by the industrial control computer. The filter communicates with the industrial control computer, sending the residual material content data of the waste liquid to the industrial control computer. Based on the residual material content data, the industrial control computer determines whether further cleaning is needed. Step 1: When the discharge machine 1 discharges material from the storage container, the pressure plate 2 moves downward in a vertical direction. At the same time, the rotating mechanism 3 moves downward in a vertical direction along with the pressure plate 2 until the pressure plate 2 moves to the bottom of the storage container, thus completing the discharge of material from the storage container. When the lower limit proximity switch has a signal, it indicates that the discharge is complete. Step 2: After the material is discharged, the pressure plate 2 moves upward in a vertical direction. At the same time, the rotating mechanism 3 moves upward in a vertical direction along with the pressure plate 2 until the pressure plate 2 rises to the target position. At this time, the upper limit proximity switch has a signal, indicating that the pressure plate 2 has reached the target position. Step 3: The operator presses the cleaning button to start the cleaning process; During cleaning, the rotating mechanism 3 drives the pressure plate 2 to rotate, and at the same time, the cleaning liquid in the storage tank 4 is sprayed onto the pressure plate 2 through the spray nozzle 6, thereby cleaning the pressure plate 2; specifically, the industrial control computer sends control commands to the rotary drive 301 and the liquid supply pump 8 respectively, the rotary drive 301 starts, and the liquid supply pump 8 starts at the same time. The rotary drive 301 drives the gear shaft 302 to rotate, thereby driving the pressure plate 2 to rotate through the gear assembly 303; The liquid supply pump 8 causes the cleaning liquid in the storage tank 4 to be sprayed into the cleaning hood 5 through the spray pipe assembly 10, thereby cleaning the rotating pressure plate 2. Step 4: Waste liquid generated during the cleaning process is collected in the first waste liquid tank 901 (i.e., the storage container in this embodiment), and under the action of the recovery pump 903, it flows into the second waste liquid tank 902 through the first pipe group 904, and then flows back into the storage tank 4 through the second pipe group 905. During the process of the waste liquid flowing through the second pipe group 905, the filter filters the waste liquid and at the same time, the material residue of the waste liquid is detected and the detection data is transmitted to the industrial control computer. The industrial control computer determines whether the cleaning of pressure plate 2 is complete based on the material residue data sent by the filter; When the industrial control computer determines that the cleaning of the pressure plate 2 is complete (i.e., the real-time data of material residue sent by the filter is less than the material residue threshold stored in the industrial control computer), the industrial control computer sends a control command to the liquid supply pump 8 again, the liquid supply pump 8 stops, the industrial control computer sends a control command to the fan, the fan starts, and blows air into the cleaning hood 5 through the air drying port 7, thereby drying the pressure plate 2 that has been cleaned. When the industrial control computer determines that the cleaning of the pressure plate 2 is not completed (i.e., the real-time data of material residue sent by the filter is greater than the material residue threshold stored in the industrial control computer), the rotary drive 301, the liquid supply pump 8, and the recovery pump 903 continue to work.
