Abstract
Description
Technical Field
[0001] The invention relates to the technical field of drainage pipe manufacturing, in particular to a manufacturing device for winding a plurality of winding layers on the outer surface of a PC drainage pipe body. Background Art
[0002] In the manufacturing process of PC drain pipes, the winding process is a crucial link. This process aims to enhance the performance of the PC drain pipe by winding one or more layers of winding film on the outer surface of the PC drain pipe body, such as improving the compressive strength, corrosion resistance and service life. However, in the actual production process, excess glue is often squeezed out between the winding film and the drain pipe body. If the overflowed glue is not handled in time, it will not only cause a waste of glue resources, but also may have a negative impact on product quality and production efficiency.
[0003] Specifically, excess glue may pollute the production environment and increase cleaning costs; it may also penetrate into the gap between the wrapping film and the drain pipe body, affecting the adhesion effect of the wrapping film and the stability of the overall structure; more seriously, excess glue may gradually seep out during the use of the drain pipe, polluting the water quality and thus damaging the interests of users.
[0004] In order to solve this problem, various methods have been tried in the prior art. For example, some manufacturers use manual wiping to remove excess glue, but this method is not only inefficient, but also difficult to ensure uniformity and thoroughness of wiping. Other manufacturers try to reduce glue overflow by improving the material or structure of the wrapping film, but this method often requires major adjustments to the existing production process and has limited effect.
[0005] Therefore, it is particularly important to develop a manufacturing device that can effectively collect and process the glue overflowed during the winding process of the PC drain pipe. Summary of the invention
[0006] The invention provides a PC drainage pipe winding manufacturing device, which realizes the effective collection and treatment of glue overflowing in the winding process through a unique design, greatly improves the production efficiency and product quality, and reduces the waste of glue.
[0007] The above technical objectives of the present invention are achieved through the following technical solutions: A PC drainage pipe winding manufacturing device, comprising: A drive shaft that is driven to rotate by a motor and is respectively fixed to both ends of the PC drainage pipe body; Glue suction boxes are provided at both ends of the PC drainage pipe body and are used to absorb glue overflowed during the winding process of the winding layer; The outer surface of the driving shaft is provided with an extrusion wheel and a contact pressure wheel through a connecting rod, and both the extrusion wheel and the contact pressure wheel rotate together with the driving shaft; The glue suction box is a long strip hollow shell structure bent into an arch, and the overall shape is an inverted "U". A number of electrically controlled glue suction one-way valves are provided on one side close to the PC drain pipe body, and a number of electrically controlled exhaust one-way valves are provided on the other side. The electrically controlled glue suction one-way valves allow substances to enter the glue suction box but do not allow substances to be discharged, and the electrically controlled exhaust one-way valves allow substances to be discharged from the glue suction box but do not allow substances to enter. A number of bulges are provided at the inner bend of the glue suction box, and each bulge is connected to the internal space of the glue suction box; A contact sensing controller is provided in the inner curved area of the glue suction box to control the working state of the electric-controlled glue suction one-way valve and the electric-controlled exhaust one-way valve; When the contact and pressure wheel keeps in contact with the inner curved wall of the glue suction box, the extrusion wheel squeezes each bulge in turn, and the glue suction box exhausts air outwards through the electrically controlled exhaust one-way valve and changes to a negative pressure state. When the contact and pressure wheel completely loses contact with the glue suction box, the glue suction box sucks glue inwards through the electrically controlled glue suction one-way valve to achieve internal and external pressure balance.
[0008] In some embodiments, a plurality of electric telescopic rods are arranged in a circular array at the end of the driving shaft. The electric telescopic rods can be telescopically adjusted along the radial direction of the driving shaft, and the telescopic ends of each electric telescopic rod can together support the inner wall of the PC drain pipe body to fix the PC drain pipe body.
[0009] In some embodiments, a top block is provided at the telescopic movable end of each electric telescopic rod. The top block is an arc-shaped plate structure that matches the shape of the inner wall of the PC drain pipe body, and the arc surface of the top block is provided with an anti-slip texture.
[0010] In some embodiments, the bottom support of the glue suction box is provided with a lifting platform, and the lifting platform can drive the glue suction box to move up and down.
[0011] In some embodiments, the glue suction box is provided with a plurality of glue discharge ports for centralized glue discharge.
[0012] In some embodiments, a flow control valve is provided at the glue discharge port to adjust and control the flow rate and speed of the glue discharged from the glue discharge port.
[0013] In some embodiments, a heating element is further provided in the glue suction box for heating the glue in the glue suction box.
[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes efficient and high-speed collection of excess glue squeezed out during the winding process of the PC drainage pipe through a unique glue suction box design and high-speed rotation of the driving shaft, thereby greatly reducing glue waste and improving the utilization rate of production materials.
[0015] The winding manufacturing device of the present invention can continuously and stably perform winding operations, while effectively collecting and processing excess glue, avoiding problems such as damage or shedding of the winding layer caused by glue residue, thereby significantly improving product quality and production efficiency.
[0016] The present invention realizes intelligent control of the electrically controlled glue suction one-way valve and the electrically controlled exhaust one-way valve through the setting of the contact sensing controller, so that the entire glue suction process is automated and intelligent, and the operation difficulty and labor cost are reduced.
[0017] In summary, the PC drainage pipe winding manufacturing device of the present invention, through its unique design and innovative technical solutions, realizes the effective collection and treatment of excess glue, improves production efficiency and product quality, and at the same time enhances the applicability and flexibility of the device, and has significant beneficial effects and economic value.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0024] like Figure 1-6 As shown, this embodiment provides a PC drain pipe winding manufacturing device, which is used to wind a plurality of winding layers 2 on the outer surface of a PC drain pipe body 1, and includes a driving shaft 3 driven to rotate by a motor and respectively fixed to both ends of the PC drain pipe body 1, and a glue suction box 4 which is also arranged at both ends of the PC drain pipe body 1 and is used to absorb glue overflowed during the winding process of the winding layer 2; The outer surface of the driving shaft 3 is provided with an extrusion wheel 304 and a contact pressure wheel 305 via a connecting rod 303, and the extrusion wheel 304 and the contact pressure wheel 305 both rotate together with the driving shaft 3; The glue suction box 4 is a long strip hollow shell structure bent into an arch, and the whole is in an inverted "U" shape. A plurality of electrically controlled glue suction one-way valves 401 are provided on one side close to the PC drain pipe body 1, and a plurality of electrically controlled exhaust one-way valves 402 are provided on the other side. The electrically controlled glue suction one-way valves 401 allow substances to enter the glue suction box 4, but do not allow substances to be discharged from the glue suction box 4. The electrically controlled exhaust one-way valves 402 allow substances to be discharged from the glue suction box 4, but do not allow substances to enter the glue suction box 4. In addition, a plurality of bulges 403 are provided at the inner bend of the glue suction box 4, and each bulge 403 is connected to the internal space of the glue suction box 4. The inner side of the curved portion of the glue suction box 4 is its inner curved area, and the arc-shaped wall surface of this area is the inner curved wall. The squeezing wheel 304 and the contact and pressure wheel 305 will pass through the inner curved area of the glue suction box 4 during the process of rotating with the driving shaft 3. When the squeezing wheel 304 and the contact and pressure wheel 305 pass through the inner curved area of the glue suction box 4, the squeezing wheel 304 will squeeze each bulge 403 in turn, and the contact and pressure wheel 305 will always keep in contact with the inner curved wall of the glue suction box 4. When the squeezing wheel 304 and the contact and pressure wheel 305 are both moved outside the inner curved area of the glue suction box 4, the squeezing wheel 304 will no longer squeeze the bulge 403, and the contact and pressure wheel 305 will also completely break away from the contact with the glue suction box 4. A contact sensing controller is provided on the inner curved wall of the glue suction box 4. When the touch-pressure wheel 305 keeps in contact with the inner curved wall of the glue suction box 4, the contact sensing controller will control the electronically controlled glue suction one-way valve 401 to keep in a two-way closed state, and at the same time control the electronically controlled exhaust one-way valve 402 to keep in a normal one-way working state. When the touch-pressure wheel 305 is completely out of contact with the glue suction box 4, the contact sensing controller will control the electronically controlled glue suction one-way valve 401 to keep in a normal one-way working state, and at the same time control the electronically controlled exhaust one-way valve 402 to keep in a two-way closed state.
[0025] By means of the above technical scheme, when the contact and pressure wheel 305 keeps contact with the inner curved wall of the glue suction box 4, the squeezing wheel 304 will squeeze each bulge 403 in turn. At this time, since the electrically controlled glue suction one-way valve 401 keeps a two-way closed state and the electrically controlled exhaust one-way valve 402 keeps a normal one-way working state, the glue suction box 4 will continuously exhaust gas outwards through each electrically controlled exhaust one-way valve 402, and the interior of the glue suction box 4 will also change from normal atmospheric pressure to negative pressure state. With the rotation of the driving shaft 3, when the contact and pressure wheel 305 is completely out of contact with the glue suction box 4, the squeezing wheel 30 4 will no longer squeeze the bulge 403. At this time, since the electronically controlled glue suction one-way valve 401 maintains a normal one-way working state and the electronically controlled exhaust one-way valve 402 maintains a two-way closed state, the glue suction box 4 will continue to suck glue inward through each electronically controlled glue suction one-way valve 401 to achieve internal and external pressure balance. During the rotation of the drive shaft 3, the winding process is also in progress. During this period, the excess glue squeezed out during the winding process of the winding layer 2 is completely absorbed by the glue suction box 4, achieving effective collection of excess glue and greatly reducing the waste of glue in the pipeline winding process. In the above process, the drive shaft 3 rotates at a high speed, so the switching speed of the contact pressure wheel 305 between the inner bending area and the non-inner bending area of the glue suction box 4 is extremely fast, so the negative pressure generation speed and glue suction speed of the glue suction box 4 are also extremely fast, which can achieve efficient and high-speed glue suction.
[0026] In some embodiments, Figure 3As shown, the end of the driving shaft 3 is provided with a plurality of electric telescopic rods 301 arranged in a circular array, each electric telescopic rod 301 can be telescopically adjusted along the radial direction of the driving shaft 3, and the telescopic ends of each electric telescopic rod 301 can support the inner wall of the PC drain pipe body 1 together to fix the PC drain pipe body 1, and the telescopic adjustment of the electric telescopic rod 301 can adapt to PC drain pipe bodies 1 of different specifications. Through such a design, the manufacturing device can firmly fix PC drain pipe bodies 1 of different specifications, ensuring that the PC drain pipe body 1 will not be displaced or shaken during the winding process, thereby ensuring the uniformity and tightness of the winding layer 2, and improving the quality and production efficiency of the product.
[0027] In some embodiments, Figure 3 As shown, the telescopic movable end of each electric telescopic rod 301 is provided with a top block 302, and the top block 302 is an arc-shaped plate-like structure that matches the shape of the inner wall of the PC drain pipe body 1, and the arc surface of the top block 302 is provided with an anti-skid texture. Through such a design, the top block 302 can better fit the inner wall of the PC drain pipe body 1, increase the contact area, and improve the stability and reliability of the fixation. At the same time, the setting of the anti-skid texture can effectively prevent relative sliding between the top block 302 and the PC drain pipe body 1, and further ensure that the PC drain pipe body 1 will not be displaced or shaken during the winding process. This not only helps to improve the uniformity and tightness of the winding layer 2, but also avoids problems such as damage or shedding of the winding layer 2 caused by the movement of the PC drain pipe body 1, thereby further improving the quality and production efficiency of the product.
[0028] In some embodiments, the bottom support of the glue suction box 4 is provided with a lifting platform, which can drive the glue suction box 4 to move up and down to adapt to PC drain pipe bodies 1 of different diameters. Through such a design, the manufacturing device can flexibly adjust the relative position between the glue suction box 4 and the PC drain pipe body 1, ensuring that the inner bending area of the glue suction box 4 can effectively cooperate with the contact pressure wheel 305 and the extrusion wheel 304, and can achieve stable glue suction and exhaust operations regardless of the diameter of the PC drain pipe body 1. This not only improves the applicability and flexibility of the manufacturing device, but also ensures that in the winding process of PC drain pipes of different specifications, the excess glue can be effectively collected and processed, further reducing the waste of glue and improving production efficiency and product quality.
[0029] In some embodiments, Figure 4As shown in Figure 5, the glue suction box 4 is provided with a plurality of glue discharge ports 404, and the glue suction box 4 is provided with a plurality of glue discharge ports 404, through which the glue is conveniently discharged in a centralized manner. With such a design, when a certain amount of glue is collected in the glue suction box 4, the glue can be conveniently discharged in a centralized manner through the glue discharge ports 404, so as to facilitate subsequent processing or recycling of the collected glue. This can not only avoid the glue suction effect of the glue suction box 4 being affected by excessive glue, but also realize the effective recycling and utilization of glue, further reduce the waste of glue, reduce production costs, and also be beneficial to environmental protection.
[0030] In some embodiments, Figure 4 As shown in Figure 5, a flow control valve is provided at the glue discharge port 404, and the flow control valve is used to adjust and control the flow rate and speed of the glue discharged from the glue discharge port 404. Through such a design, the discharge amount of glue can be accurately controlled according to actual production needs and process requirements to avoid glue waste or insufficient discharge. At the same time, the setting of the flow control valve can also realize real-time monitoring and adjustment of the glue discharge process, further improving the production efficiency and product quality of the manufacturing device, reducing production costs, and enhancing the reliability and stability of the equipment.
[0031] In some embodiments, a heating element is also provided in the glue suction box 4, for heating the glue in the glue suction box 4 to maintain the fluidity and temperature stability of the glue. By such a design, it is possible to effectively prevent the glue from solidifying or becoming sticky due to the low temperature in the glue suction box 4, ensuring that the glue can be smoothly sucked into the glue suction box 4 through the electric control glue suction one-way valve 401, and discharged smoothly through the glue discharge port 404. This not only improves the working efficiency and reliability of the glue suction box 4, but also can avoid equipment failure or production interruption caused by the solidification or stickiness of the glue, further ensuring the production efficiency and product quality of the manufacturing device. At the same time, the setting of the heating element can also be temperature regulated and controlled according to actual needs, to adapt to different types of glue and production process requirements, and enhance the applicability and flexibility of the manufacturing device.
[0032] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
