Description

Technical Field

[0001] This application relates to the field of padding processing equipment, and more specifically, to a spiral plastic pad winding device. Background Technology

[0002] Plastic mats are mats made primarily of plastic. They are typically lightweight, wear-resistant, corrosion-resistant, waterproof, and insulating. Some plastic mats also have good elasticity and flexibility and are easy to process and shape. Plastic mat winding devices are equipment used to wrap plastic mats or stretch films around objects. The core purpose of this device is to provide specialized processing equipment for lining the inner walls of underground pipe networks.

[0003] However, most existing equipment guides the raw material to form using only a single shaft without setting a dedicated trajectory limiting structure on the shaft. This results in a lack of stable basic trajectory constraints during the conveying and winding process of the raw material, making it prone to problems such as trajectory deviation, surface wrinkles, or local deformation during the spiral bending process.

[0004] In view of this, we propose a spiral plastic pad winding device. Summary of the Invention

Detailed Implementation

[0015] The present application will be further described in detail below with reference to the accompanying drawings.

[0016] Reference Figures 1-3This application discloses a spiral plastic mat winding device, including a spiral winding body 100 and a feeding mechanism 200. The spiral winding body 100 includes a track 110 laid at the bottom of a manhole. A fixing ring 120 is fixedly connected to the top of the track 110. Four casters 130 are slidably connected to the top of the track 110 through the fixing ring 120. Two circular rings 140 are fixedly connected to the top of the four casters 130 at their front and rear ends, respectively. Inner support devices 141 are evenly distributed on the circular rings 140. A rotating shaft 142 and a fixed shaft 143 are also installed on the circular rings 140. The fixed shaft 143 has an opening... It has a spiral groove; the feeding mechanism 200 is equipped with a hydraulic motor 210 and a drive wheel 220, the drive wheel 220 is in contact with the surface of the strip speed pad to realize the conveying of the strip speed pad; the spiral groove of the rotating shaft 142 is equipped with a guide device 150, the guide device 150 includes a guide plate 151 installed on the spiral groove; the inner support device 141 is evenly distributed in the circumferential direction in the middle of the ring 140; the width of the strip speed pad is 148mm, the groove width of the spiral groove is adapted to the width of the strip speed pad, and the inner diameter of the spiral barrel-shaped plastic pad formed by the spiral winding device is 750mm; Before starting the equipment, the track 110 must be laid smoothly at the bottom of the manhole. After the track 110 is laid, the fixing ring 120 above it will be in the preset working position. The four casters 130 installed on the fixing ring 120 can move freely back and forth along the track 110. Subsequently, the movement of the casters 130 will drive the main components of the equipment to run along the predetermined trajectory, avoiding processing deviations due to unstable foundation. The operator slowly puts a 148mm wide strip of feed pad into the equipment from the ground manhole. The raw material first enters the feeding mechanism 200. When feeding, it is necessary to ensure that... The strip speed pad is free of wrinkles and damage, and its initial position is aligned with the feed inlet of the feeding mechanism 200. The power of the feeding mechanism 200 comes from the driving hydraulic system. The hydraulic station provides continuous and stable power support for the feeding process, driving the hydraulic motor 210 to operate. After the hydraulic motor 210 outputs power, it directly drives the drive wheel 220 to rotate at a uniform speed. Because the drive wheel 220 is in close contact with the surface of the strip speed pad, the drive wheel 220 accurately conveys the strip speed pad along the preset downward path through the action of friction. Under the conveying of the feeding mechanism 200, the strip speed pad enters the spiral... In the processing area between the front and rear ends of the winding body 100, a rotating shaft 142 and a fixed shaft 143 are mounted on the rotating shaft 140. The rotating shaft 142 has a spiral groove adapted to the width of the strip-shaped speed pad, and a guiding device 150 is provided for the spiral groove. When the strip-shaped speed pad enters the spiral groove, the guiding plate 151 in the guiding device 150 can contact the edge of the strip-shaped speed pad, and the position of the material is corrected in real time through physical limiting. Under the cooperative guidance of the fixed shaft 143 and the rotating shaft 142, the strip-shaped speed pad is gradually bent into a spiral shape. This step is performed on the fixed shaft 143. The spiral grooves on the top provide a basic trajectory for the raw material forming. The matching guide device 150 and the guide plate 151 therein can correct the position of the raw material in real time and avoid the raw material from shifting left and right during the forming process. At the same time, the inner support device 141, which is evenly distributed along the circumference in the middle of the ring 140, forms support from the inside of the raw material and prevents the raw material from being excessively deformed due to spiral bending. Under the synergistic effect of multiple structures, the final formed spiral barrel-shaped plastic pad has a uniform spiral trajectory and a flat surface, which meets the requirements of the stability of the pad structure for the installation on the inner wall of the underground pipeline network and avoids installation and fitting problems caused by forming deviation.

[0017] Reference Figures 1-3 The outer wall of the fixed shaft 143 is provided with multiple mounting grooves 1431. The inner groove of the mounting groove 1431 is fixedly connected with two retaining rings 160 by bolts. A support frame 161 is fixedly connected to the top of one retaining ring 160. An elastic sheet 162 is fixedly connected to the top of the support frame 161 to support the two sides of the strip-shaped speed pad. After being corrected by the guide device 150, the strip speed pad continues to move along the spiral groove of the rotating shaft 142. At the same time, the fixed shaft 143 begins to rotate synchronously with the assistance of the hydraulic system. The outer wall of the fixed shaft 143 has multiple mounting grooves 1431. Two retaining rings 160 are fixedly connected in the mounting grooves 1431 by bolts. The support frame 161 fixed to the top of one of the retaining rings 160 extends upward. The elastic plate 162 at the top of the support frame 161 directly contacts the two side edges of the strip speed pad. The elastic force of the elastic plate 162 holds the two sides of the material. The guide plate 151 in the guide device 150 can correct the conveying position of the strip speed pad in real time, further preventing the material from shifting to the left or right. The elastic plate 162 fixed in the mounting groove 1431 on the outer wall of the fixed shaft 143 by the retaining rings 160 and the support frame 161 can apply elastic force from both sides of the material to prevent it from falling and tilting due to gravity during the spiral bending process.

[0018] In summary, when using the spiral plastic pad winding device disclosed in this application embodiment, before starting the equipment, the track 110 must be laid smoothly at the bottom of the manhole. After the track 110 is laid, the fixing ring 120 above it will be in the preset working position. The four casters 130 installed on the fixing ring 120 can move freely back and forth along the track 110. Subsequently, the movement of the casters 130 will drive the main body of the equipment to run along the predetermined trajectory, avoiding processing deviations due to unstable foundation. The operator will then place the 148mm wide strip from the ground manhole. The pad is slowly placed into the equipment. The raw material first enters the feeding mechanism 200. During placement, it must be ensured that the strip-shaped speed pad is free of wrinkles and damage, and its initial position is aligned with the feed inlet of the feeding mechanism 200. The feeding mechanism 200 is powered by a hydraulic system. The hydraulic station provides continuous and stable power support for the feeding process, driving the hydraulic motor 210. After the hydraulic motor 210 outputs power, it directly drives the drive wheel 220 to rotate at a uniform speed. Because the drive wheel 220 is in close contact with the surface of the strip-shaped speed pad, through friction, the drive wheel 220 propels the strip-shaped speed pad along a preset downward path. Precise delivery: The strip-shaped speed-grinding pad is conveyed by the feeding mechanism 200 into the processing area between the two rings 140 at the front and rear ends of the spiral winding body 100. A rotating shaft 142 and a fixed shaft 143 are mounted on the rings 140. The rotating shaft 142 has a spiral groove adapted to the width of the strip-shaped speed-grinding pad, and a guiding device 150 is provided for the spiral groove. When the strip-shaped speed-grinding pad enters the spiral groove, the guiding plate 151 in the guiding device 150 can contact the edge of the strip-shaped speed-grinding pad, physically limiting and correcting the position of the material in real time. Under the coordinated guidance of the fixed shaft 143 and the rotating shaft 142... The strip-shaped speed pad is gradually bent into a spiral shape. After being corrected by the guide device 150, the strip-shaped speed pad continues to move along the spiral groove of the rotating shaft 142. At the same time, the fixed shaft 143 begins to operate synchronously with the assistance of the hydraulic system. The outer wall of the fixed shaft 143 has multiple mounting grooves 1431. Two retaining rings 160 are fixedly connected in the mounting grooves 1431 by bolts. The support frame 161 fixed to the top of one of the retaining rings 160 extends upward. The elastic plate 162 at the top of the support frame 161 directly contacts the two side edges of the strip-shaped speed pad. The elastic force of the elastic plate 162 holds the two sides of the raw material.
