Description

Technical Field

[0001] This utility model relates to the field of PVC pipe production technology, and in particular to a conveying device for PVC pipe processing. Background Technology

[0002] PVC pipes, a common type of plastic pipe, are made of polyvinyl chloride resin and are widely used in construction, municipal engineering, agriculture, and other fields. They have gained market recognition due to their excellent performance. They are lightweight, making handling and installation easier and reducing labor costs during construction. They are also durable, able to withstand certain pressures, meeting the transportation needs of various scenarios. They exhibit outstanding corrosion resistance, are not easily corroded by water, acids, alkalis, etc., extending their service life and reducing maintenance frequency. Their smooth surface reduces water flow resistance, helping to improve transportation efficiency and preventing bacterial growth, ensuring the cleanliness of the transported medium. Furthermore, PVC pipe production technology is relatively mature, raw materials are widely available, and prices are relatively affordable, making them suitable for large-scale promotion and use.

[0003] During PVC pipe processing, the freshly formed pipes are at a high temperature and need to be conveyed to subsequent processes via a conveying device. Traditional conveying devices lack a dedicated cooling structure and rely solely on natural cooling, which is inefficient. Delayed cooling can easily cause pipe deformation during transport, affecting product dimensional accuracy. Furthermore, natural cooling is time-consuming, reducing overall production efficiency. In addition, some simple cooling devices suffer from uneven water flow distribution and unstable cooling effects, making them unsuitable for conveying pipes of different specifications. Poor coordination between conveying and cooling can also cause scratches on the pipe surface, increasing the product defect rate. These devices fail to meet the requirements of efficient cooling and stable conveying in large-scale production. Therefore, a conveying device for PVC pipe processing is needed.

[0028] Please see Figure 1-7 This utility model provides a technical solution: a conveying device for PVC pipe processing, wherein:

[0029] The base 2 is fixedly connected to the bottom of the workbench 1, providing stable support for the entire device. It is also fixedly connected to the water tank 3, enhancing the stability of the water tank 3 installation, ensuring the stability of the water storage space, and preventing the device from shaking during operation, which could affect the overall structural stability.

[0030] Water tank 3 is fixed to the bottom of workbench 1. It stores water for cooling and has water pump 4 fixedly connected to its surface, providing a base for the installation of water pump 4. After the water pump 4 is started, it can draw water from water tank 3 to form the initial power for water circulation and ensure a continuous supply of cooling water.

[0031] The water pump 4 is fixedly connected to the water pipe 5, which transports the pumped water to the cooling pipe 6. The water pipe 5 is also fixedly connected to the workbench 1 to ensure the stability of the water transport path and prevent water leakage caused by pipe shaking during water transport, thus ensuring that the water is efficiently transported to the cooling pipe 6.

[0032] Cooling pipes 6 are fixed at equal intervals on the surface of the workbench 1. There are multiple cooling pipes 6 and they are interconnected by a connector 7. The connector 7 is set between adjacent cooling pipes 6 so that the water flow can be evenly distributed between each cooling pipe 6, ensuring that the surface temperature of each cooling pipe 6 is consistent and improving the overall cooling uniformity.

[0033] The conveying assembly 8 is rotatably sleeved on the outer surface of the cooling pipe 6. The number of the conveying assembly 8 is the same as that of the cooling pipe 6. It is made of conveying roller material with rounded corners or right-angled grooves to adapt to different specifications of PVC pipes. The low temperature of the cooling pipe 6 is transferred to the conveying assembly 8 through contact, so as to achieve synchronous cooling during the conveying process.

[0034] The top of the workbench 1 is fixedly connected to the support plate 17, the surface of the support plate 17 is fixed to the motor 18, the output end of the motor 18 is fixed to the gear A19, the gear A19 meshes with the gear B20 on the outer surface of the conveying component 8, or the pulley 9 sleeved on the outer surface of the conveying component 8 is driven by the belt 10 to drive all the conveying components 8 to rotate synchronously, so as to ensure the conveying stability.

[0035] The first support 11 is fixed on the top of the workbench 1, the hydraulic cylinder 13 is fixed on the top of the first support 11, the lifting frame 14 is fixed at the output end of the hydraulic cylinder 13, and the pressure roller 15 is rotatably connected to the bottom of the lifting frame 14. The position of the pressure roller 15 is adjusted by driving the lifting frame 14 through the hydraulic cylinder 13, which can flexibly adapt to different conveying scenarios.

[0036] A second support 12 is fixed on the top of the workbench 1, and multiple cooling fans 16 are fixed on the top of the second support 12. The air outlet of each cooling fan 16 is located below the second support 12, blowing air onto the PVC pipe being transported. This, combined with the water cooling method of the cooling pipe 6, forms a composite cooling effect, further improving the cooling efficiency.

[0037] The various structures cooperate with each other through fixed connections, transmission connections, etc. The water tank 3, water pump 4, water pipe 5, cooling pipe 6 and communicating vessel 7 constitute a water circulation cooling system. The motor 18, gear, pulley 9 and belt 10 drive the conveying assembly 8 to achieve stable conveying. The hydraulic cylinder 13 and cooling fan 16 enhance the adaptability of the device and the cooling effect, thereby improving the overall production efficiency and product quality.

[0038] Working principle: After the water pump 4 starts, the water in the water tank 3 is transported through the water pipe 5 to multiple cooling pipes 6 that are fixed at equal intervals on the surface of the workbench 1. The cooling pipes 6 are interconnected through the connector 7 to achieve water circulation. The conveying component 8 is rotated and sleeved on the outer surface of the cooling pipe 6. The gear A19 at the output end of the motor 18 meshes with the gear B20 on the outer surface of the conveying component 8. Through the pulley 9 and belt 10, all conveying components 8 are driven to rotate to transport PVC pipes. The hydraulic cylinder 13 at the top of the first support 11 drives the lifting frame 14 to adjust the position of the pressure roller 15 to ensure stable conveying. The cooling fan 16 at the top of the second support 12 blows air downward from the air outlet to assist in cooling. The conveying component 8 is adapted to different PVC pipes. The whole system uses the circulating water in the cooling pipe 6 and the cooling fan 16 to cool the PVC pipes being transported.

[0039] Example 1:

[0040] When conveying PVC round pipes, the conveying assembly 8 uses a conveying roller with rounded corner grooves. The rounded corner grooves fit tightly with the outer surface of the round pipe, which can reduce shaking during the conveying process. Combined with the low-temperature transmission of the cooling pipe 6, it can achieve stable cooling and conveying.

[0041] When it is necessary to transport PVC square tubes, the conveying assembly 8 is replaced with a conveying roller with a right-angled groove. The right-angled groove is adapted to the edges of the square tube, which enhances the positioning effect of the square tube during the transport process and avoids the square tube from shifting and affecting the uniformity of cooling.

[0042] The replaced conveying assembly 8 is still rotated and sleeved on the outer surface of the cooling pipe 6. It maintains synchronous operation through the meshing of gear A19 and gear B20 or the transmission of pulley 9 and belt 10, ensuring that pipes of different shapes can obtain stable conveying power and cooling effect.

[0043] Example 2:

[0044] The motor 18 is fixed on the surface of the support plate 17. When the gear A19 at its output end meshes with the gear B20 on the outer surface of the conveying component 8, it can precisely control the rotation speed of the conveying component 8. This is suitable for scenarios with high requirements for conveying accuracy, ensuring that the pipe passes through the cooling area at a uniform speed.

[0045] When the motor 18 drives the conveying assembly 8 through the pulley 9 and belt 10, the belt drive has a certain buffering effect, which can reduce vibration during the conveying process. It is suitable for conveying thin-walled PVC pipes that are easily affected by vibration, and reduces the risk of damage to the pipes caused by vibration.

[0046] The cooling fan 16 is fixed on the top of the second bracket 12. In normal temperature environment, it can enhance air flow and accelerate heat dissipation of the pipe. In high temperature production environment, the airflow it blows can reduce the ambient temperature around the cooling pipe 6 and improve the synergistic cooling efficiency of water cooling and air cooling.

[0047] Example 3:

[0048] In a small PVC pipe processing plant, the device is placed at the end of the production line. The pipes to be processed directly enter the conveying component 8. Ordinary cooling water is injected into the water tank 3. The water pump 4 drives the water to flow through the water pipe 5 into the cooling pipe 6. The cooling fan 16 is turned on to assist in cooling. It is suitable for continuous cooling of small batches and multiple specifications of pipes. It is simple to operate and easy to maintain.

[0049] After the device is started, the position of the lifting frame 14 is adjusted by the hydraulic cylinder 13 to make the connection between the water pipe 5 and the cooling pipe 6 smoother. The conveying component 8 selects the corresponding groove type according to the shape of the pipe. The motor 18 drives the conveying component 8 to operate through belt drive to meet the flexible production needs of small factories.

[0050] In large PVC pipe production bases, this device is integrated into automated production lines. Water tank 3 is connected to an external circulating water system to ensure a continuous water supply, and cooling fan 16 is used in conjunction with the workshop's central air conditioning to improve the overall cooling rate.

[0051] The conveying speed is precisely controlled by the gear transmission of motor 18, so that the residence time of the pipe in the cooling zone is consistent. This ensures that the cooling effect of each pipe is uniform during mass production, and reduces product quality fluctuations caused by cooling differences.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
