Description

Technical Field

[0001] This utility model relates to the field of PVC mesh fabric processing technology, specifically a PVC mesh fabric stretching and shaping device. Background Technology

[0002] PVC mesh fabric is a specially treated fabric, mainly made of polyvinyl chloride (PVC). PVC mesh fabric achieves waterproof, windproof, and breathable properties by coating the fabric surface with a PVC coating, forming a uniform covering material. This coating is made by dissolving the required coating particles in solvent or water, applying it evenly to the fabric, and then drying and curing it in an oven.

[0003] PVC mesh stretching and shaping equipment mainly includes stretching machines, extruders, coating machines, shaping machines, and drying equipment. These devices play a crucial role in the production process of PVC mesh.

[0004] Conventional mesh stretching and shaping equipment requires manual adjustment by operators during operation. Since the adjustment is relatively inconvenient inside the drying chamber, the adjustment operation is time-consuming and labor-intensive. At the same time, impurities generated during processing will be output to the outside with the airflow, causing unnecessary environmental pollution.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a PVC mesh fabric stretching and shaping device. Utility Model Content

[0006] The purpose of this invention is to provide a PVC mesh fabric stretching and shaping device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PVC mesh fabric stretching and shaping device, comprising a drying chamber and a first stretching structure. An air inlet pipe is installed on the top of the drying chamber, and exhaust pipes are installed on both the left and right sides of the drying chamber. The first stretching structure is horizontally mounted in the center of the drying chamber, and a second stretching structure is installed at both the front and rear ends of the first stretching structure. The first stretching structure includes an electric feeding roller, an electric slider, a guide frame, a fixed pile, and a support frame. An electric slider is installed at both the left and right ends of the electric feeding roller, and a guide frame is connected to the middle of the electric slider. A fixed pile is installed at both the front and rear ends of the guide frame, and a support frame is horizontally connected to both the upper and lower ends of the fixed pile.

[0008] Furthermore, the drying box includes a shaping box, a material inlet and outlet, an air inlet, an exhaust outlet, and a filter screen. The shaping box has material inlets and outlets on both the front and rear sides, and an air inlet is provided at the top inside the shaping box. The shaping box also has exhaust outlets symmetrically arranged on the left and right sides inside, and a filter screen is installed inside both the exhaust outlet and the exhaust outlet.

[0009] Furthermore, four sets of inlet and outlet ports are provided on the top side inside the shaping box, and the exhaust ports are symmetrically arranged on the inner side of the shaping box.

[0010] Furthermore, the air intake pipe adopts an "I" shaped structure, and the bottom of the air intake pipe is provided with four sets of connection port structures. Moreover, the air intake pipe and the outer top of the shaping box are connected to each other by a flange structure.

[0011] Furthermore, the exhaust pipe and the outer side of the shaping box are connected by a flange structure, and the exhaust pipe is set with an adjustable bending composite duct structure.

[0012] Furthermore, the electric slider and the guide frame are connected to each other in a sliding keyway structure, and the first tension structure is connected and fixed to the second tension structure through a fixed pile.

[0013] Furthermore, the second stretching structure includes an auxiliary stretching roller, an adjusting slider, a guide rail frame, and an adjusting bolt. Adjusting sliders are installed at both ends of the auxiliary stretching roller, and the end of the adjusting slider away from the auxiliary stretching roller is connected to the guide rail frame. An adjusting bolt is vertically installed on the top of the adjusting slider.

[0014] Furthermore, the adjusting slider and the guide rail frame are connected to each other by a sliding keyway structure, and the adjusting bolt and the adjusting slider are connected by a thread.

[0015] This utility model provides a PVC mesh fabric stretching and shaping device, which has the following beneficial effects:

[0016] 1. This utility model features a first stretching structure horizontally mounted inside a drying oven, with second stretching structures symmetrically connected to its front and rear ends. An electric slider drives an electric conveying roller to automatically move back and forth along the surface of a guide frame. Adjusting the slider allows for the forward and backward movement of an auxiliary stretching roller along the guide frame. The position of the auxiliary stretching roller can be manually fine-tuned by adjusting the tightness of the adjusting bolt. This structure enables automatic structural adjustment to stretch the PVC mesh fabric while allowing for flexible tension adjustment, ensuring the effectiveness of the stretching and shaping of the PVC mesh fabric and guaranteeing the flexibility of the device's operation, facilitating real-time adjustments by operators.

[0017] 2. This utility model, by installing an "I"-shaped air inlet pipe on the top of the drying oven and coordinating with four sets of air inlets inside the shaping box, ensures that the hot air generated by the external heating fan can quickly and evenly enter the interior of the drying oven, guaranteeing uniform heating of the PVC mesh fabric inside. Since both the air inlet and exhaust pipes are flanged and installed on the external surface of the drying oven, the structure offers both sufficient structural stability and relatively easy disassembly for maintenance. Furthermore, filters are installed inside both the air inlet and exhaust ports to prevent unnecessary impurities from being carried into the drying oven by the hot air, thus avoiding affecting the processing quality of the PVC mesh fabric. It also minimizes the impact of impurities generated during the processing of the PVC mesh fabric on the external environment caused by evaporating water vapor, ensuring the safe operation of the device. Additionally, the exhaust pipe uses an adjustable-bend composite conduit structure for flexible connection to external waste gas treatment equipment. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] like Figures 1 to 5 As shown, a PVC mesh stretching and shaping device includes a drying chamber 1 and a first stretching structure 4. An air inlet pipe 2 is installed on the top of the drying chamber 1, and exhaust pipes 3 are installed on both the left and right sides of the drying chamber 1. The first stretching structure 4 is horizontally mounted in the center of the drying chamber 1, and second stretching structures 5 are installed at both the front and rear ends of the first stretching structure 4. The first stretching structure 4 includes an electric conveying roller 401, an electric slider 402, a guide frame 403, a fixing pile 404, and a support frame 405. Electric sliders 402 are installed at both the left and right ends of the electric conveying roller 401, and the guide frame 403 is connected to the middle of the electric slider 402. Fixing piles 404 are installed at both the front and rear ends of the guide frame 403, and support frames 405 are horizontally connected to the upper and lower ends of the fixing piles 404. The electric slider 402 and the guide frame 403 are connected to each other via a sliding keyway structure. The first stretching structure 4 is connected to the second stretching structure 5 through the fixing piles 404. The components 5 are interconnected and fixed. The second tensioning structure 5 includes an auxiliary tensioning roller 501, an adjusting slider 502, a guide rail frame 503, and an adjusting bolt 504. Adjusting sliders 502 are installed at both ends of the auxiliary tensioning roller 501. The end of the adjusting slider 502 away from the auxiliary tensioning roller 501 is connected to the guide rail frame 503. The adjusting bolt 504 is vertically installed on the top of the adjusting slider 502. The adjusting slider 502 and the guide rail frame 503 are connected to each other in a sliding keyway structure. The adjusting bolt 504 is threadedly connected to the adjusting slider 502. The operation of the electric slider 402 can drive the electric conveying roller 401 to automatically move back and forth along the surface of the guide frame 403. The structure of the adjusting slider 502 can be used to move the auxiliary tensioning roller 501 back and forth along the surface of the guide rail frame 503. The position of the auxiliary tensioning roller 501 can be manually fine-tuned by adjusting the tightness of the adjusting bolt 504.

[0026] like Figures 1 to 5As shown, the drying oven 1 includes a shaping box 101, an inlet / outlet 102, an air inlet 103, an exhaust outlet 104, and a filter screen 105. The shaping box 101 has inlet / outlet 102 on both its front and rear sides, and an air inlet 103 is located at the top interior of the shaping box 101. The interior of the shaping box 101 also has symmetrically arranged exhaust outlets 104, and each exhaust outlet 104 is fitted with a filter screen 105. Four sets of inlet / outlet 102 are located on the top interior side of the shaping box 101, and the exhaust outlets 104 are symmetrically arranged on the interior sides of the shaping box 101. The air inlet pipe 2 adopts an "I"-shaped structure. The drying oven 1 is equipped with an air inlet pipe 2, which has four sets of connection ports at its bottom. The air inlet pipe 2 is connected to the top of the shaping box 101 via a flange structure. The exhaust pipe 3 is connected to the outer side of the shaping box 101 via a flange structure. The exhaust pipe 3 is designed with an adjustable bend composite conduit structure. By installing an "I" shaped air inlet pipe 2 on the top of the drying oven 1, and with four sets of air inlets 103 inside the shaping box 101, it is possible to ensure that the hot air generated by the external heating fan can enter the interior of the drying oven 1 quickly and evenly, so as to ensure that the surface of the PVC mesh cloth inside the drying oven 1 is heated evenly.

[0027] In summary, as Figures 1 to 5 As shown, when using the PVC mesh stretching and shaping equipment, the PVC mesh to be processed is first passed through two sets of auxiliary stretching rollers 501 symmetrically arranged at the front and rear, and two sets of electric conveying rollers 401 arranged in the middle. The mesh is rolled around the surface one by one to ensure the conveying of the mesh and thus maximize the stability of the mesh during conveying.

[0028] Then, using the flange structure at the top center of the air inlet pipe 2, in conjunction with the use of the pipe structure, it is connected to the external hot air blower equipment to ensure that the hot air generated by the hot air blower can be quickly delivered to the interior of the shaping box 101.

[0029] During the conveying and processing of PVC mesh fabric, the electric slider 402 will drive the electric conveying roller 401 to move horizontally along the surface of the guide frame 403. At the same time, the operator can adjust the tightness of the adjusting bolt 504 on the upper side of the adjusting slider 502 as needed, and then use the adjusting slider 502 to move and adjust the auxiliary stretching roller 501 along the surface of the guide frame 503, thereby realizing the function of manual fine-tuning stretching to ensure the processing effect of PVC mesh fabric.

[0030] As the PVC mesh fabric is processed, the filters 105 inside the air inlet 103 and the exhaust outlet 104 will purify and filter the air flowing inside the drying oven 1, so as to avoid affecting the processing quality of the mesh fabric and also to avoid the processing of the mesh fabric from affecting the external environment.

[0031] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
