Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe cleaning, in particular to a spraying device for plastic pipe production. Background Art

[0002] After the plastic pipe is extruded, its temperature is high and its shape is unstable. It needs to be spray-cooled to reduce the temperature of the plastic pipe, quickly shape it, and maintain the specified size and shape. For example, when producing PVC pipes, spray cooling can make the outer diameter and wall thickness of the pipe meet the standard requirements as soon as possible, thereby improving production efficiency. Rapid and effective cooling can shorten the residence time of the pipe on the production line, thereby speeding up the production rhythm and improving overall production efficiency.

[0003] Chinese patent application number CN208020697U discloses a spraying device for plastic pipe production, comprising a housing, a water storage chamber, a temperature sensor, a first cooling pipe, a spiral pipe, a nozzle, a cooling chamber, a second cooling pipe, a first water pump, a proximity switch, a plastic pipe, a water inlet pipe, a solenoid valve, a second water pump, a water level sensor, a cooling fan, and a control box. The water storage chamber is disposed within the housing and is internally mounted with a temperature sensor; the spiral pipe is connected to the water storage chamber via the first cooling pipe and is mounted with several nozzles; the cooling chamber is disposed on the upper side of the water storage chamber, and a second cooling pipe is mounted on the cooling chamber and a side of the water storage chamber. The arrangement of the water storage chamber and cooling chamber facilitates liquid flow and allows all liquid to flow into the first and second cooling pipes, facilitating market promotion and application.

[0004] In actual use, a large amount of moisture remains on the surface of the plastic pipe after spraying. This can cause dust to stick to the pipe during subsequent processing, affecting product quality and appearance. For example, during transportation or storage, the adhered dust may become embedded in the plastic pipe surface, making it difficult to clean. This not only reduces the pipe's aesthetics but also may affect its performance. Furthermore, if the dust contains corrosive substances, it may accelerate aging and damage to the pipe, shortening its service life. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 5As shown, a spraying device for plastic pipe production includes two legs 1, a table 2 is fixedly mounted on the top of the two legs 1, a push plate 4 is slidably mounted on the upper end of the table 2, a driving mechanism 3 for driving the push plate 4 is mounted on the lower portion of the table 2, a connecting frame 5 is screwed and mounted in the middle of the top of the table 2, a spraying mechanism 6 is mounted on the connecting frame 5, and a rolling drying mechanism 7 is disposed on the left side of the upper portion of the leg 1;

[0025] By setting up a spray mechanism 6, the pipes on the table 2 are sprayed and rinsed. At the same time, by setting up a driving mechanism 3 to drive the push plate 4 to slide, the pipes on the table 2 can be pushed to slide through the spray mechanism 6 at a uniform speed, so that every part of the plastic pipe can be fully sprayed and rinsed. By setting up a rolling wiping mechanism 7, the plastic pipes after spraying are rolled and wiped to avoid moisture remaining on the surface of the plastic pipes after spraying, thereby preventing the adhered dust from being embedded in the surface of the plastic pipes and causing adverse effects during subsequent transportation or storage.

[0026] Specifically, the spray mechanism 6 includes a water tank 61 and a water distribution tank 64. The water tank 61 is fixedly mounted between the opposite surfaces of the two legs 1. A water pump 62 is fixedly mounted on the bottom wall of the inner cavity of the water tank 61. The output end of the water pump 62 is connected to the top of the water distribution tank 64 through a water pipe 63. The water distribution tank 64 is fixedly mounted on the top of the connecting frame 5. A plurality of nozzles 65 connected to the inner cavity of the water distribution tank 64 are equidistantly mounted at the bottom end.

[0027] Start the water pump 62, which draws the water in the water tank 61 into the spray mechanism 6 through the water pipe 63. As the water in the spray mechanism 6 increases, the pressure in the inner cavity of the spray mechanism 6 will also increase. In this way, the water in the inner cavity of the spray mechanism 6 will be sprayed downward through multiple nozzles 65 to spray and rinse the plastic pipes on the table 2.

[0028] Furthermore, two baffles 21 are symmetrically installed on both sides of the top of the table 2 away from the middle thereof, and a through slot 22 is opened in the middle of the top of the table 2;

[0029] The top of the table 2 is V-shaped and the bottom of the slope is located in the middle of the table 2.

[0030] Two baffles 21 are provided to prevent water from flowing along the table top 2 to the ground when the spraying mechanism 6 is spraying. At the same time, the top of the table top 2 is V-shaped and a penetrating groove 22 is provided at the bottom of the slope. In this way, the water gathered at the upper end of the table top 2 will flow into the water tank 61 through the groove 22 for recycling.

[0031] Specifically, the drive mechanism 3 includes a servo motor 31 and a screw rod 32. The screw rod 32 is rotatably mounted between the two legs 1. The servo motor 31 is fixedly mounted on the rightmost leg 1. The output shaft of the servo motor 31 is fixedly connected to the screw rod 32 via a coupling. A nut 33 is threadedly mounted on the outer surface of the screw rod 32. The top of the nut 33 is fixedly connected to the bottom of the push plate 4.

[0032] Place multiple plastic tubes on the top of the table 2, start the servo motor 31, and the servo motor 31 drives the screw rod 32 to rotate, so that the nut 33 threadedly installed on the outer surface of the screw rod 32 drives the push plate 4 to push the multiple plastic tubes on the table 2. In this way, during the process of the multiple plastic tubes being pushed, the spray mechanism 6 can evenly spray water onto the multiple plastic tubes to clean them.

[0033] Specifically, the rolling wiping mechanism 7 includes a frame 71, which is fixedly mounted on the left side of the top of the table 2. A top plate 72 is fixedly mounted on the top of the frame 71, a fixing frame 73 is fixedly mounted on the top of the top plate 72, and a motor 79 is fixedly mounted on the fixing frame 73.

[0034] A double-groove pulley 78 is rotatably mounted on the top of the top plate 72. The double-groove pulley 78 is fixedly connected to the output shaft of the motor 79 through a coupling. The top of the top plate 72 is located on both sides of the motor 79 and is rotatably mounted with connecting rods 76. The tops of the two connecting rods 76 are respectively mounted with a single-groove pulley 1 74 and a single-groove pulley 2 75. The single-groove pulley 1 74, the single-groove pulley 2 75 and the double-groove pulley 78 are distributed in a triangular shape. The single-groove pulley 1 74 and the single-groove pulley 2 75 are respectively connected to the double-groove pulley 78 through two transmission belts 791. The bottom ends of the two connecting rods 76 are fixedly mounted with brush rollers 77.

[0035] Start the motor 79, which drives the double-groove pulley 78 to rotate. The double-groove pulley 78 drives the single-groove pulley 1 74 and the single-groove pulley 2 75 to rotate together through two transmission belts 791, thereby driving the two brush rollers 77 at the bottom of the single-groove pulley 1 74 and the single-groove pulley 2 75 to rotate together. In this way, after the driving mechanism 3 drives the push plate 4 to push the multiple plastic tubes on the table 2 to be sprayed by the spray mechanism 6, the multiple plastic tubes that have been sprayed clean are continued to be pushed by the push plate 4. After passing through the two rotating brush rollers 77, the brush roller 77 wipes the moisture on the multiple plastic tubes.

[0036] It should be noted that the specific installation method, circuit connection method and control method of the servo motor 31, water pump 62 and motor 79 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
