Description

Technical Field

[0001] The utility model relates to the technical field of geomembrane processing, in particular to a geomembrane hot press. Background Art

[0002] Geomembranes are geotechnical anti-seepage materials made by combining plastic film with non-woven fabrics as the anti-seepage substrate. The anti-seepage performance of new geomembranes depends primarily on the plastic film's anti-seepage properties. Plastic films used for anti-seepage applications both domestically and internationally primarily include polyvinyl chloride, polyethylene, and EVA. ECB is also used in tunnel applications. These are flexible polymer materials with low specific gravity, high extensibility, high deformation adaptability, and excellent corrosion, low-temperature, and frost resistance.

[0003] As a composite material, geomembrane requires hot pressing to form a single piece of geomembrane from multiple materials. Existing hot presses mostly use a stamping mechanism, which is inconvenient for hot pressing longer geomembranes, making them difficult to adapt to streamlined, efficient production, and impractical. Furthermore, the high heat generated during the hot pressing process can easily damage the geomembrane's external structure, necessitating cooling, which is inconvenient with existing equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a geomembrane hot press, which has the advantages of roller hot pressing to facilitate the assembly line production of geomembranes, ensure production capacity, facilitate processing and effective air cooling to ensure processing quality, and solve the problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a geomembrane hot press, comprising a frame and a bottom box, the bottom box being fixed in the middle of the bottom end of the frame, and air ducts being equidistantly embedded and installed on both sides of the bottom box, a groove being provided in the middle of the upper end face of the bottom box, frames being fixed on both sides of the frame, and drive boxes being slidably installed on the upper and lower ends of the frames, a rotating shaft being rotatably installed between the two drive boxes of the same height, two rotating shafts being provided in total, and a lower jacket and an upper jacket being respectively fixed on the outer sides of the two rotating shafts, and an infrared ranging box being fixed on both sides of the top end of the frame.

[0006] When using a geomembrane hot press in this technical solution, the geomembrane is introduced into the center position inside the frame through the feeding mechanism. The internal infrared rangefinder of the infrared rangefinder box is started to detect the distance of the geomembrane. Then, the external motor of the frame is started to drive the screw rod to rotate. The screw rod drives the control nut sleeve to displace through the thread. The positive and negative threads at both ends of the screw rod respectively drive the corresponding nut sleeves, so that two corresponding driving boxes move relatively. The driving box drives the lower clamping sleeve and the upper clamping sleeve to approach each other through the rotating shaft, realizing the clamping of the upper and lower sides of the geomembrane. Then, the motor in the driving box is started to drive the lower clamping sleeve and the upper clamping sleeve to rotate, realizing the clamping and feeding of the geomembrane. The heating rods are started to heat the lower clamping sleeve and the upper clamping sleeve, and the heat passes through the lower clamping sleeve and the upper clamping sleeve to form hot pressing processing on the geomembrane. During the processing, the built-in fan of the air duct is started to send air into the bottom box, and then discharged to the geomembrane through the exhaust window, avoiding damage to the processed products caused by excessive temperature.

[0007] Preferably, anti-slip pads are fixed on the outer side of the lower end surface of the frame. There are four anti-slip pads in total, and the four anti-slip pads are arranged in an array. Anti-slip pads are fixed at the lower ends of the anti-slip pads. The frame is placed and supported through the anti-slip pads, and the anti-slip pads improve the friction force to ensure the stability of the support.

[0008] Preferably, a fan is provided inside the air duct, and a protective net is provided outside the air duct. Exhaust windows are equally spaced and installed on both sides of the upper end surface of the bottom box. The external air flow enters the bottom box through the fan, and then the air flow is discharged to the geomembrane through the exhaust window.

[0009] Preferably, the groove is adapted to the lower clamping sleeve. Cleaning brushes are fixed on both sides inside the groove, and the cleaning brushes are attached to the lower clamping sleeve. After the lower clamping sleeve descends, it is received through the groove, and the cleaning brushes can clean the surface of the rotating lower clamping sleeve during the receiving process.

[0010] Preferably, receiving grooves are annularly and arrayedly distributed on the outer side of the rotating shaft, and heating rods are fixed in the receiving grooves. The heating rods are attached to the inside of the lower clamping sleeve and the upper clamping sleeve. The lower clamping sleeve and the upper clamping sleeve can be heated through the heating rods to realize hot pressing processing.

[0011] Preferably, nut sleeves are fixed on both sides of the rear end of the driving box. Screw rods are rotatably installed on both sides inside the frame, and the screw rods penetrate through the corresponding nut sleeves through the threads. The lifting of the driving box is realized by the rotation of the screw rod driving the corresponding nut sleeve through the thread.

[0012] Preferably, positive threads and negative threads are respectively provided at both ends of the screw rod, and the positive and negative threads respectively drive the corresponding nut sleeves through the threads. The relative displacement of the corresponding two nut sleeves is realized through the positive and negative threads on the screw rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: It is powered by an external power supply. The operator starts the device through an external control device, guides the geomembrane into the middle position inside the frame through a feeding mechanism, starts the infrared ranging detection inside the infrared ranging box to detect the distance of the geomembrane, and then starts the external motor of the frame to drive the screw rod to rotate. The screw thread of the screw rod drives the control nut sleeve to displace. The left-handed and right-handed threads at both ends of the screw rod respectively drive the corresponding nut sleeves, so that two corresponding driving boxes move relative to each other. The driving box drives the lower clamping sleeve and the upper clamping sleeve to approach each other through the rotating shaft, realizing the clamping of the upper and lower sides of the geomembrane. Then, starting the motor in the driving box can drive the lower clamping sleeve and the upper clamping sleeve to rotate, realizing the clamping and feeding of the geomembrane. Start the heating rod to heat the lower clamping sleeve and the upper clamping sleeve, and its heat passes through the lower clamping sleeve and the upper clamping sleeve to form hot pressing on the geomembrane. During the processing, start the built-in fan of the air duct to send air into the bottom box and then discharge it to the geomembrane through the exhaust window to avoid damage to the processed product caused by excessive temperature. The device has a simple structure and is easy to operate. It performs hot pressing through a roller clamping method, which is convenient for hot pressing of longer geomembranes, facilitating the realization of pipeline production, ensuring production capacity, and at the same time having a temperature reduction and heat dissipation mechanism to avoid affecting the production quality due to excessive temperature.
