Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, in particular to a cleaning device before spraying a hydrophobic layer on a plastic pipe. Background Art

[0002] Before spraying the hydrophobic layer on the plastic pipe, the cleanliness of the pipe surface is directly related to the bonding effect between the hydrophobic layer and the pipe, as well as the quality and service life of the hydrophobic layer itself. If there are oil stains, dust, foreign particles or even residual release agents from previous processing on the pipe surface, on the one hand, the adhesion between the hydrophobic coating and the pipe wall will decrease, and the coating will easily peel off during subsequent use; on the other hand, these impurities mixed into the hydrophobic coating will destroy the uniformity and density of the coating, making it unable to perform its hydrophobic function well.

[0003] The existing Chinese patent with publication number CN217191378U discloses a rotating cleaning device for the outer wall of a pipe, which drives a brush roller to rotate by starting a driving motor, so that the rotating brush roller cleans the pipe body.

[0004] However, the dust or impurities cleaned from the outer wall of the pipe will splash to the outside of the equipment, polluting the surrounding environment and making it inconvenient to collect sewage in a centralized manner. In addition, the overall length of the device needs to match the length of the pipe, which will cause it to occupy a larger space and increase the cost of use in various aspects.

[0005] Therefore, a cleaning device is needed before spraying the hydrophobic layer of a plastic pipe. Summary of the invention

[0006] In order to solve all or part of the above problems, the purpose of the present invention is to provide a plastic pipe hydrophobic layer pre-spray cleaning device to solve the problem proposed in the above-mentioned comparative document technology that the cleaned dust or impurities will splash to the outside of the equipment, pollute the surrounding environment and make it inconvenient to collect sewage centrally, and occupy a large space and increase the cost of use.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cleaning device before spraying a hydrophobic layer on a plastic pipe, comprising a cleaning component and a plurality of support frames, a pipe body is placed on the inner side of the cleaning component and on the upper side of the support frames, the cleaning component comprises a workbench, a driving mechanism is fixedly installed on one side of the workbench, a rotating mechanism is rotatably installed on one side of the workbench, the driving mechanism and the rotating mechanism are in a meshing state, a cleaning mechanism is fixedly installed inside the workbench, a conveying platform is fixedly installed on the other side of the workbench, a transmission mechanism is arranged inside the workbench, and the transmission mechanism is meshingly connected with the driving mechanism and the conveying platform; Under the action of gravity, the pipeline prompts the workbench and the cleaning mechanism to jointly perform closed cleaning on the pipeline cleaning part, and under the drive of the driving mechanism, it drives the transmission mechanism to drive the conveying platform to convey the pipeline forward for cleaning and drives the rotating mechanism to rotate the pipeline for cleaning.

[0008] Furthermore, the workbench includes a bottom plate and support plates located on both sides of the upper end of the bottom plate, a semicircular plate is fixedly installed on the upper end of the support plate, an arc groove is opened inside the semicircular plate, two arc plates are slidably installed inside the semicircular plate, an air inlet is opened on one side of the semicircular plate, and the air inlet is connected to the arc groove; The conveying platform includes a bearing arc plate fixedly connected to the surface of one side of the semicircular plate, a cavity is opened on one side of the bearing arc plate close to the semicircular plate, the cavity corresponds to and is connected with the air inlet hole, a cavity box is fixedly installed on the lower surface of the bearing arc plate, an air pipe is fixedly installed on one side of the cavity box, the air pipe is connected with the cavity box, one end of the air pipe away from the cavity box passes through the bearing arc plate and is connected with the cavity, a pressure rod is installed through the inside of the bearing arc plate, the pressure rod is slidably connected with the bearing arc plate, a receiving plate is fixedly installed on the upper end of the pressure rod, the lower end of the pressure rod passes through the cavity box and is located inside it, and a pressure plate is fixedly installed on the lower end of the pressure rod, the pressure plate is in contact with the inner wall of the cavity box and is slidably connected, a return spring is fixedly installed on the lower end of the pressure plate, and the lower end of the return spring is fixedly connected to the inner bottom wall of the cavity box. When the pipeline is placed above the conveying platform, first When the air in the airbox is in contact with the receiving plate, the pressure rod and the receiving plate are exerted downward pressure due to the mass of the pipe, causing the pressure rod and the receiving plate to drop. During the dropping process, the return spring is compressed, forcing the gas inside the cavity box to enter the cavity through the air pipe, and finally enter the arc groove through the air inlet. As the gas inside the arc groove increases, the two arc plates are forced to move along the curvature of the arc groove to wrap the pipe, which is convenient for subsequent centralized collection. After the cleaning of the pipe is completed, the return spring is reset and lifts the pressure rod and the receiving plate upward to draw the gas inside the arc groove back into the cavity box. Without the gas bearing capacity and the factors of their own mass, the two arc plates return to their initial positions along the curvature of the arc groove, which is convenient for the placement of the next pipe.

[0009] Furthermore, a groove is provided at one end of the arc plate. In the initial state, the two arc plates are in a fit state with each other, which prevents the gas from entering the arc groove from the air inlet hole. The opening of the groove allows the gas to first enter the space formed by the two grooves through the air inlet hole. Subsequently, as the gas continues to enter, the two arc plates are pushed to both sides and finally enter the arc groove, completing the subsequent gas entry.

[0010] Furthermore, the cleaning mechanism includes two groups of arc rods 1 fixedly connected to the inner wall surface of the semicircular plate, both ends of the arc rod 1 are provided with grooves, and torsion springs are symmetrically fixedly installed on the surface of the grooves, and an arc rod 2 is fixedly installed at one end of the two torsion springs close to each other, and a flushing nozzle and a fixed rod are fixedly installed between the two groups of arc rods 2 located at the same end of the two groups of arc rods 1, and a brush roller is fixedly installed on the outer side of the fixed rod. Because the arc rod 1 and the arc rod 2 are connected by the torsion spring, the arc rod 2 can expand to both sides when the pipeline is placed, which is convenient for the placement of the pipeline. When the pipeline is placed, the torsion force generated by the torsion spring reset drives the arc rods 2 on both sides to move toward the center, thereby realizing adaptive clamping of the pipeline, thereby forcing the brush roller to fit tightly with the outer wall surface of the pipeline. At the same time, due to the inclination angle setting of the flushing nozzle, the contact point between the brush roller and the outer wall of the pipeline is efficiently flushed, further improving the cleaning effect.

[0011] Furthermore, a plurality of guide grooves are provided on the inner wall surface of the semicircular plate, a sewage trough is provided just below the inner wall of the semicircular plate, a soft water pipe is fixedly installed on the lower end of the flushing nozzle, and the input end of the soft water pipe passes through the sewage trough.

While protecting the environment, it saves water resources and reduces costs. Flushing and cleaning is achieved by connecting the input end of the soft water pipe to the water supply pipe.

[0012] Furthermore, the driving mechanism includes a fixing part fixedly connected to the base plate, a servo motor is fixedly installed on the upper end of the fixing part, a rotating shaft is fixedly installed on the output end of the servo motor, and a gear ring is fixedly installed on one side of the outer surface of the rotating shaft. The rotating shaft is driven to rotate by the servo motor, and the gear ring is driven to rotate, thereby providing driving force for the subsequent transmission mechanism and rotating mechanism operation.

There are two groups of transmission mechanisms, and the structural composition and function are exactly the same. The gear ring drives the gear one and the transmission rod one to rotate during the rotation process, and the bevel gear meshes with the meshing teeth, which drives the transmission rod two to rotate. The transmission rod two drives the gear two and the fixed shaft to rotate through the bevel gear during the rotation process. One group of fixed shafts drives the other group of fixed shafts and gear two to rotate through a belt during the rotation process. The gear two meshes with the gear three during the rotation process, thereby driving the connecting rod and the rubber roller to rotate. After the pipeline is placed, it contacts the rubber roller, and finally the pipeline is transported, so that the cleaning component does not need to match the length of the pipeline to achieve full cleaning of the pipeline.

[0014] Furthermore, the rotating mechanism includes a planetary gear meshing with a ring gear, a fixing ring is fixedly installed on the inner side of the planetary gear, a rubber part is fixedly installed inside the fixing ring, the rubber part and the rubber roller are at the same horizontal plane height, and the ring gear drives the planetary gear to rotate while rotating, and the planetary gear drives the fixing ring and the rubber part to rotate while rotating, so that a huge friction force is generated between the rubber part and the pipeline, and then drives the pipeline to rotate, so that the pipeline rotates simultaneously during the transportation process, and since the brush roller and the flushing nozzle are symmetrically arranged in two groups, the outer wall of the pipeline can be fully cleaned.

[0015] Furthermore, a ring groove is provided on one side surface of the fixed ring, and two ring parts are fixedly installed on one side of the semicircular plate. The ring parts match the ring groove and are slidably connected. By matching the ring groove and being slidably connected, the stability of the rotating mechanism during operation is greatly enhanced, ensuring the cleaning effect.

[0016] Furthermore, a driven wheel 1 is rotatably installed on the upper part of the support frame, and a driven wheel 2 is rotatably installed on the outer side of the fixed rod. Through the arrangement of the driven wheel 1 and the driven wheel 2, the pipeline is assisted in conveying and rotating, thereby improving the running smoothness.

[0021] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1-2A plastic pipe hydrophobic layer pre-spray cleaning device comprises a cleaning component 1 and a plurality of support frames 2, a pipe body 3 is placed on the inner side of the cleaning component 1 and on the upper side of the support frames 2, the cleaning component 1 comprises a workbench 11, a driving mechanism 12 is fixedly installed on one side of the workbench 11, a rotating mechanism 16 is rotatably installed on one side of the workbench 11, the driving mechanism 12 is meshed with the rotating mechanism 16, a cleaning mechanism 13 is fixedly installed inside the workbench 11, a conveying platform 15 is fixedly installed on the other side of the workbench 11, a transmission mechanism 14 is arranged inside the workbench 11, and the transmission mechanism 14 is meshed and connected with the driving mechanism 12 and the conveying platform 15, First, the pipeline is placed above the workbench 11, multiple support frames 2 and the conveying platform 15. At this time, under the action of gravity, the pipeline prompts the workbench 11 and the cleaning mechanism 13 to perform closed cleaning on the pipeline cleaning part, and under the drive of the driving mechanism 12, the transmission mechanism 14 drives the conveying platform 15 to convey the pipeline forward for cleaning and drives the rotating mechanism 16 to rotate the pipeline for cleaning, so that during the cleaning process, not only will waste water not be splashed, but it will also be convenient for centralized collection of waste water. At the same time, the pipeline can be rotated and conveyed forward while being cleaned, which not only makes the cleaning more comprehensive, greatly enhances the cleaning effect, but also reduces the space occupied by the equipment.

[0023] Combination Figure 4-5 , Fig. 9 The workbench 11 includes a bottom plate 111 and support plates 112 located on both sides of the upper end of the bottom plate 111. A semicircular plate 113 is fixedly installed on the upper end of the support plate 112. An arc groove 114 is formed inside the semicircular plate 113. Two arc plates 119 are slidably installed inside the semicircular plate 113. An air inlet 117 is formed on one side of the semicircular plate 113. The air inlet 117 is connected to the arc groove 114. The conveying platform 15 includes a bearing arc plate 151 fixedly connected to the surface of one side of the semicircular plate 113, and a cavity 158 is opened on the side of the bearing arc plate 151 close to the semicircular plate 113, and the cavity 158 corresponds to and communicates with the air inlet hole 117. A cavity box 152 is fixedly installed on the lower surface of the bearing arc plate 151, and an air pipe 157 is fixedly installed on one side of the cavity box 152. The air pipe 157 is connected to the cavity box 152, and one end of the air pipe 157 away from the cavity box 152 passes through the bearing arc plate 151 and is connected to the cavity 158. The pressure rod 153 is connected to the supporting arc plate 151, and the pressure rod 153 is slidably connected to the supporting arc plate 151. The upper end of the pressure rod 153 is fixedly installed with a receiving plate 154. The lower end of the pressure rod 153 passes through the cavity box 152 and is located inside it, and the lower end of the pressure rod 153 is fixedly installed with a pressure plate 155, which fits with the inner wall of the cavity box 152 and is slidably connected. The lower end of the pressure plate 155 is fixedly installed with a return spring 156, and the lower end of the return spring 156 is fixedly connected to the inner bottom wall of the cavity box 152.

[0024] Specifically, when the pipeline is placed on the conveying platform 15, it first contacts the receiving plate 154, and then, due to the mass of the pipeline itself, a downward pressure is generated on the receiving plate 154 and the pressure rod 153, causing the pressure rod 153 and the receiving plate 154 to descend, and in the process of descending, the return spring 156 is compressed, forcing the gas inside the cavity box 152 to enter the cavity 158 through the air pipe 157, and finally enter the arc groove 114 through the air inlet hole 117. The increase of the internal gas of the arc groove 114 forces the two arc plates 119 to move along the curvature of the arc groove 114, so as to wrap the pipe, so that the waste water will not splash during the cleaning process and the waste water can be collected centrally. After the cleaning of the pipe is completed, the reset spring 156 resets and pushes up the pressure rod 153 and the receiving plate 154, so that the gas inside the arc groove 114 is sucked back into the cavity box 152, and the two arc plates 119 automatically reset, so as to facilitate the closed cleaning of the next pipe.

[0025] Combination Figure 6 A groove 1191 is provided at one end of the arc plate 119. In the initial state, the two arc plates 119 are in a fitted state, which prevents the gas from entering the arc groove 114 from the air inlet hole 117. The opening of the groove 1191 allows the gas to first enter the space formed by the two grooves 1191 through the air inlet hole 117. Subsequently, as the gas continues to enter, the two arc plates 119 are pushed to both sides, and finally enter the arc groove 114, completing the subsequent gas entry.

[0026] Combination Figure 7 The cleaning mechanism 13 includes two groups of arc rods 131 fixedly connected to the inner wall surface of the semicircular plate 113, and grooves 132 are provided at both ends of the arc rod 131. Torsion springs 133 are symmetrically fixedly installed on the surface of the grooves 132, and an arc rod 134 is fixedly installed at one end of the two torsion springs 133 close to each other. A flushing nozzle 135 and a fixed rod 137 are fixedly installed between the two groups of arc rods 134 at the same end of the two groups of arc rods 131, and a brush roller 139 is fixedly installed on the outside of the fixed rod 137. Because the arc rod 131 and the arc rod 134 are connected by the torsion spring 133, the arc rod 134 can expand to both sides when the pipeline is placed, which is convenient for the placement of the pipeline.

[0027] Furthermore, when the pipe is placed, the torsion force generated by the torsion spring 133 resets the pipe, driving the arc rods 134 on both sides to move toward the center, thereby achieving adaptive clamping of the pipe, thereby forcing the brush roller 139 to fit tightly against the outer wall surface of the pipe. At the same time, due to the inclination angle setting of the flushing nozzle 135, the contact point between the brush roller 139 and the outer wall of the pipe is efficiently flushed, further improving the cleaning effect.

[0028] Combination Figure 4-5 , Figure 7 A plurality of guide grooves 116 are provided on the inner wall surface of the semicircular plate 113, a sewage trough 118 is provided just below the inner wall of the semicircular plate 113, a soft water pipe 136 is fixedly installed at the lower end of the flushing nozzle 135, and the input end of the soft water pipe 136 passes through the sewage trough 118. The opening of the guide grooves 116 allows the sewage generated during the cleaning process to flow along the guide grooves 116 to and be concentrated in the sewage trough 118 and discharged, which is convenient for subsequent recycling and treatment. While protecting the environment, it saves water resources and reduces costs. The input end of the soft water pipe 136 is connected to the water supply pipe to achieve flushing and cleaning.

The gear ring 124 drives the gear 1 141 and the transmission rod 1 142 to rotate during the rotation process. Because the bevel gear 146 at one end of the transmission rod 2 145 is meshed with the meshing teeth 143, it drives the transmission rod 2 145 to rotate. The transmission rod 2 145 rotates during the rotation process. During the process, the bevel gear 146 at the other end of the transmission rod 145 drives the corresponding gear 2 1472 and the fixed shaft 1471 to rotate. One group of fixed shafts 1471 drives another group of fixed shafts 1471 and gear 2 1472 to rotate through the belt 1474 during the rotation. The gear 2 1472 engages with the gear 3 1593 during the rotation, thereby driving the connecting rod 1592 and the rubber roller 1591 to rotate. After the pipeline is placed, it contacts the rubber roller 1591, and finally the pipeline is transported, so that the cleaning component 1 does not need to match the length of the pipeline, and can achieve full-process forward transportation cleaning of the pipeline.
