Description

Technical Field

[0001] This utility model relates to a geomembrane storage device, belonging to the technical field of geomembrane production equipment. Background Technology

[0002] During the production of geomembrane, after the rear winding roller finishes winding, it needs to be removed and replaced with a new one to continue production. However, while the winding roller is being replaced, the front-end production equipment continues to produce. At this time, the produced geomembrane will be suspended and piled up, or even fall to the ground and become contaminated as waste film. When winding is restarted, the waste film needs to be cut off and the remaining part needs to be rewound onto the winding roller. This operation not only wastes raw materials but also affects the continuity of production and reduces production efficiency. Utility Model Content

[0003] Based on the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a geomembrane storage device to solve the problems of raw material waste and low production efficiency caused by changing the winding roller in the geomembrane production process in the prior art.

[0004] The geomembrane storage device of this utility model includes a frame, on which a lifting component is movably mounted. The lifting component is driven by a motor and can move up and down along the vertical beam of the frame. Horizontal supports are provided on the lower part of both sides of the frame along the width direction, and multiple fixed rollers are evenly installed above the horizontal supports on both sides. Multiple lifting rollers are rotatably mounted on the lifting component, and the lifting rollers and fixed rollers are arranged alternately in the horizontal direction.

[0005] The lifting assembly includes a connecting beam, with lifting slides fixedly connected to both ends of the connecting beam. Rollers are rotatably installed at the four corners of the lifting slides, and the lifting slides are slidably connected to the vertical beams of the frame through the rollers.

[0006] Preferably, worm gear jacks are fixed to the bottom of both sides of the frame, and the worm gear jacks on both sides are connected by a drive shaft; the motor is set on one side of the frame, and the output shaft of the motor is connected to the worm gear jack on the same side, so that the worm gear jacks on both sides can be driven to move synchronously by one motor.

[0007] Preferably, the output end of the worm gear jack is connected to the bottom end of the lead screw, and the top end of the lead screw is rotatably connected to the bearing mounting plate on the top of the frame; the lead screw nut seat is fixedly connected to the lead screw nut connecting plate on the lifting slide plate; the motor drives the lead screw to rotate through the worm gear jack, thereby driving the lifting slide plate to move up and down.

[0008] Furthermore, the fixed roller is rotatably connected to the cross brace on both sides via vertical bearing seats; the lifting roller is rotatably connected to the lifting slide plate on both sides via horizontal bearing seats.

[0009] Preferably, an upper limit switch and a lower limit switch are installed on the vertical beam of the frame, and a sensor plate is installed on the lifting slide. The sensor plate cooperates with the upper limit switch and the lower limit switch to limit the movement limit of the lifting slide.

[0010] The advantages of this utility model compared with the prior art are:

[0011] 1. This utility model forms a retractable film storage path by staggered fixed rollers and lifting rollers. When changing the winding roller, the geomembrane continuously produced at the front end can be temporarily stored, preventing the geomembrane from being suspended and piled up, or falling to the ground and being contaminated. There is no need to cut off the waste film, which significantly reduces raw material loss and lowers production costs.

[0012] 2. No downtime is required during the replacement of the take-up roller. The front-end production equipment can run continuously. After the replacement is completed, the stored geomembrane can be quickly released to resume normal winding, effectively improving the overall operating efficiency of the production line.

[0013] 3. This utility model uses a single motor in conjunction with a transmission shaft to drive the worm gear lift on both sides to move synchronously, ensuring that the lifting components on both sides are raised and lowered synchronously without tilting or deviating.

[0014] 4. The worm gear jack and screw drive have a self-locking function to prevent the lifting components from sliding down unexpectedly; together with the upper and lower limit switches, automatic limit is achieved to avoid overtravel operation, and the equipment operates stably, safely and reliably.

[0021] The present invention will be further described below with reference to specific embodiments.

[0022] like Figure 1-5 As shown, this embodiment is achieved through the following technical solution: It includes a frame 1, on which a lifting assembly is movably mounted. The lifting assembly is driven by a motor 4 and can move up and down along the vertical beam of the frame 1. Horizontal supports 19 are provided along the width direction on the lower part of both sides of the frame 1, and multiple fixed rollers 6 are evenly installed above the horizontal supports 19 on both sides. Multiple lifting rollers 13 are rotatably mounted on the lifting assembly, and the lifting rollers 13 and fixed rollers 6 are staggered in the horizontal direction. The lifting assembly includes a connecting beam 16, with lifting slide plates 2 fixedly connected to both ends of the connecting beam 16. Rollers 17 are rotatably mounted at the four corners of the lifting slide plates 2, and the lifting slide plates 2 are slidably connected to the vertical beam of the frame 1 through the rollers 17.

[0023] In this embodiment, worm gear jacks 5 are fixed at the bottom of both sides of the frame 1, and the worm gear jacks 5 on both sides are connected by a transmission shaft 12; the motor 4 is set on one side of the frame 1, and the output shaft of the motor 4 is connected to the worm gear jack 5 on the same side, so that the worm gear jacks 5 on both sides can be driven to move synchronously by one motor 4.

[0024] The output end of the worm gear jack 5 is connected to the bottom end of the lead screw 3, and the top end of the lead screw 3 is rotatably connected to the bearing mounting plate 18 on the top of the frame 1; the lead screw nut seat of the lead screw 3 is fixedly connected to the lead screw nut connecting plate 14 on the lifting slide plate 2; the motor 4 drives the lead screw 3 to rotate through the worm gear jack 5, thereby driving the lifting slide plate 2 to move up and down.

[0025] The fixed roller 6 is rotatably connected to the cross brace 19 on both sides via vertical bearing seats 8; the lifting roller 13 is rotatably connected to the lifting slide plate 2 on both sides via horizontal bearing seats 9.

[0026] An upper limit switch 10 and a lower limit switch 11 are installed on the vertical beam of the frame 1, and an induction plate 15 is installed on the lifting slide plate 2. The induction plate 15 cooperates with the upper limit switch 10 and the lower limit switch 11 to limit the movement limit of the lifting slide plate 2.

[0027] The working process of this utility model is as follows:

[0028] Under normal production conditions, the lifting component is in a low position, the lifting roller 13 and the fixed roller 6 are at similar heights, and the geomembrane 7 passes around the fixed roller 6 and the lifting roller 13 in an S-shape, and is transported to the rear winding equipment in the shortest path.

[0029] When the rear take-up roller finishes taking up its winding and a new take-up roller needs to be replaced, the motor 4 is started. The motor 4 drives the lead screw 3 to rotate through the worm gear lift 5, which drives the lifting slide plate 2 to move upward along the vertical beam of the frame 1, and drives the lifting roller 13 to rise synchronously. Since the lifting roller 13 and the fixed roller 6 are arranged alternately, the conveying path of the geomembrane 7 is lengthened after the lifting roller 13 rises. The geomembrane 7 continuously produced by the front-end production equipment is temporarily stored to prevent the geomembrane 7 from falling to the ground and being contaminated. When the lifting slide plate 2 moves up to the upper limit switch 10 position, the sensing plate 15 triggers the upper limit switch 10, the motor 4 stops running, and the lifting assembly remains at the maximum film storage position.

[0030] After the take-up roller is replaced, the motor 4 is started in reverse to drive the lifting slide plate 2 to move downwards, smoothly releasing the stored geomembrane 7 until the induction plate 15 triggers the lower limit switch 11, the lifting assembly is reset, and the equipment returns to normal production status.
