Description

Technical Field

[0001] The invention relates to the technical field of geomembrane processing equipment, in particular to a film pressing and forming device for producing and processing geomembrane. Background Art

[0002] In the patent application with application announcement number CN218256880U, it includes a mounting plate, a base plate and a threaded rod, the upper end surface of the base plate is installed with a support plate, and there are two support plates in total, and the two support plates are symmetrically distributed with respect to the base plate, and a top plate is installed at the upper end of the support plate, and a first limiting wheel group and a second limiting wheel group are rotatably installed between the support plates, and the first limiting wheel group and the second limiting wheel group are symmetrically distributed with respect to the support plates, and side end surfaces of the two support plates are provided with mounting grooves, and the threaded rod is rotatably installed in the mounting groove, and movable blocks symmetrically distributed are threadedly installed on the threaded rod, and a connecting rod is installed on the movable block, and the mounting plate is installed at the end of the connecting rod, and pressure rollers are rotatably installed between the mounting plates, and two pressure rollers are symmetrically distributed. The advantages are: during use, the distance between the pressure rollers can be adjusted according to the thickness of the geomembrane to be processed. During adjustment, the threaded rod can be rotated by the driving device in the first driving box. With the cooperation of the two movable blocks, the distance between the pressure rollers can be changed, the distance between the two pressure rollers can be increased or decreased, and the two pressure rollers can be conveniently used to process geomembranes of different thicknesses.

[0003] In the prior art including the above-mentioned patents, temperature is a key factor affecting the thickness and quality of geomembranes during production. If the temperature is too high, the geomembrane will be over-softened after extrusion, and the softened raw materials will flow to both sides, resulting in uneven thickness of the geomembrane. If the temperature is too low, the basic raw materials cannot be pressed together well. There are no corresponding temperature control measures in the above-mentioned patents, which is not conducive to better ensuring the quality of the geomembrane. In the prior art, some equipment will use external temperature control devices, which will increase the footprint of the device. Summary of the invention

The water outlet pipes are also used to connect the upper and lower fixed plates. The other ends of the water inlet pipe and the water outlet pipe are connected to the water pump and thermostat assembly. A valve is arranged between the water outlet pipe and the water pump and thermostat assembly, and the valve is used to adjust the water output in the pressure roller, so as to change the pressure inside the pressure roller by adjusting the water output.

[0008] Preferably, a piston is arranged in the middle of the pressure roller, a sliding rod is arranged inside the pressure roller, four sliding rods are evenly distributed around the center line of the pressure roller, both ends of the sliding rod are fixedly connected to the fixed plate, and the piston is slidably connected to the sliding rod.

[0009] Preferably, a connecting tube is slidably provided in the middle of the piston, the outer surface of the connecting tube is slidably connected to the sliding rod, both ends of the connecting tube are fixedly provided with bellows, the other end of the bellows is fixedly connected to the fixed plate, and the bellows is simultaneously connected to the water inlet pipe.

[0010] Preferably, a sealing plug is fixedly provided in the middle of the piston, the diameter of the sealing plug is larger than the inner diameter of the connecting pipe, the sealing plug is used to block the connecting pipe, and the sliding rod can simultaneously limit the range of movement of the piston, the connecting pipe and the bellows.

[0011] Preferably, the rolling assembly includes a sleeve, which is slidably connected to the piston, located inside the pressure roller, fixed in the pressure roller by interference fit, and a through hole 1 is provided on the outer surface of the sleeve, and a through hole 2 is provided outside the through hole 1 through the pressure roller.

[0012] Preferably, the through hole 2 is opened in a funnel shape, the diameter of the through hole 1 is smaller than the minimum diameter of the through hole 2, a top column is slidably arranged inside the through hole 2, the outer end of the top column is flush with the pressure roller in a default state, and a pressure column is fixedly arranged on the side of the top column close to the sleeve.

[0013] Preferably, the pressure column is tangent to the inner wall of the sleeve, a sealing gasket is fixedly provided on the outer surface of the pressure column, a support plate is provided around the pressure column, one end of the support plate is fixedly connected to the top column, and the other end of the support plate is fixedly connected to the sealing gasket.

[0014] Preferably, a sealing gasket 2 is fixedly arranged between the support plates, the sealing gasket 1 and the sealing gasket 2 are both made of rubber, the inside of the sealing gasket 1 and the sealing gasket 2 are filled with water, the support plates are made of spring steel, and the inclination angle of the support plates is greater than the inclination angle of the through hole 2.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) During the geomembrane processing, the hot and cold water circulation system in the roller plays a key role in temperature control. By adjusting the injection and circulation of hot and cold water, the geomembrane can be maintained in an appropriate processing temperature range. When the temperature is too high, cold water is pumped into the roller. Due to the large specific heat capacity of water, it can quickly absorb the heat of the geomembrane to prevent it from becoming unevenly thick and thin due to overheating. When the temperature is too low, hot water enters the roller to provide sufficient heat for the geomembrane to ensure that it can be fully compacted. When it is necessary to switch the heat conduction mode, that is, switch between hot and cold water, the synergistic effect between water pressure and piston plays an efficient drainage function. Under this mechanism, the original water in the roller can be quickly discharged, so that the newly injected water can immediately fully contact the inner wall of the roller and start heat exchange. This process greatly shortens the time for adjusting the surface temperature of the roller and reduces the time the temperature is in an inappropriate range, thereby effectively reducing the adverse effects on the quality and efficiency of geomembrane production, significantly improving the effect and stability of the entire temperature control system, and ensuring the high precision and high quality of geomembrane processing. (2) During the processing of geomembrane, the push pin can be pushed out by increasing the water pressure inside the pressure roller. When the push pin is pushed out, it will contact the surface of the geomembrane and press out a pit. The geomembrane with these pits can significantly enhance the friction between it and the ground when it is actually used later. It is worth mentioning that the push pin can be used to quickly change the type of geomembrane. In the past, if you want to change the type of geomembrane, you need to replace different processing equipment. However, this equipment only needs to adjust the water pressure inside the pressure roller to change the different states of the push pin, so as to achieve the purpose of changing the type of geomembrane. The operation is convenient and efficient. On the other hand, the push pin itself can also participate in the heat conduction process. During the entire processing process, only the water pressure inside the pressure roller needs to be appropriately adjusted to achieve the corresponding functional change. Compared with the traditional method of replacing the pressure roller, this method of using the push pin is more efficient and does not have any negative impact on the efficiency of heat conduction. It ensures that while efficiently changing the characteristics of the geomembrane, it can still maintain good processing temperature control and heat conduction effect, thereby ensuring the overall quality and efficiency of geomembrane processing.

A rolling assembly 3 is arranged inside the calendering assembly 2, and the rolling assembly 3 can press holes on the geomembrane.

[0021] The calendering assembly 2 includes a pressing roller 201, both ends of which are rotatably provided with fixed disks 202. The fixed disks 202 are located inside the frame 1, and two upper and lower fixed disks are provided on one side of the fixed disk 202. The fixed disk 202 does not rotate with the pressing roller 201, and a water inlet pipe 203 is provided in the middle of one side of the fixed disk 202.

[0022] The water inlet pipe 203 is a three-way pipe, which connects the upper and lower fixed plates 202. Water outlet pipes 204 are arranged on both sides of the water inlet pipe 203.

A valve 206 is arranged between the water outlet pipe 204 and the water pump and thermostat assembly 205. The valve 206 is used to adjust the water output in the pressure roller 201. The pressure inside the pressure roller 201 is changed by adjusting the water output. The water inlet pipe 203 and the water outlet pipe 204 can form a loop to circulate the internal water to ensure the stability of the temperature.

[0023] A piston 207 is arranged in the middle of the pressure roller 201, and a slide rod 208 is arranged inside the pressure roller 201. Four slide rods 208 are evenly distributed around the center line of the pressure roller 201. Both ends of the slide rod 208 are fixedly connected to the fixed plate 202, and the piston 207 is slidably connected to the slide rod 208.

[0024] A connecting pipe 209 is slidably provided in the middle of the piston 207, and the outer surface of the connecting pipe 209 is slidably connected to the sliding rod 208. Bellows 211 are fixedly provided at both ends of the connecting pipe 209, and the other end of the bellows 211 is fixedly connected to the fixed disk 202.

[0025] A sealing plug 210 is fixedly provided in the middle of the piston 207. The diameter of the sealing plug 210 is larger than the inner diameter of the connecting tube 209. The sealing plug 210 is used to block the connecting tube 209. The sliding rod 208 can simultaneously limit the range of movement of the piston 207, the connecting tube 209 and the bellows 211.

[0026] The rolling assembly 3 includes a sleeve 301, which is slidably connected to the piston 207. The sleeve 301 is located inside the pressure roller 201. The sleeve 301 is fixed in the pressure roller 201 by interference fit. A through hole 1 302 is provided on the outer surface of the sleeve 301. A through hole 2 303 is provided on the outer side of the through hole 1 302 through the pressure roller 201. The through hole 1 302 on the sleeve 301 can cooperate with the pressure column 305 and the sealing gasket 1 306 to prevent water leakage when the top column 304 is not ejected.

[0027] Through hole 2 303 is opened in a funnel shape, the diameter of through hole 1 302 is smaller than the minimum diameter of through hole 2 303 , a top column 304 is slidably arranged inside through hole 2 303 , the outer end of the top column 304 is flush with the pressure roller 201 in the default state, and a pressure column 305 is fixedly arranged on one side of the top column 304 close to the sleeve 301 .

[0028] The pressure column 305 is tangent to the inner wall of the sleeve 301, and a sealing gasket 306 is fixedly provided on the outer surface of the pressure column 305. Support plates 307 are provided around the pressure column 305, one end of the support plate 307 is fixedly connected to the top column 304, and the other end of the support plate 307 is fixedly connected to the sealing gasket 306.

[0029] A sealing gasket 308 is fixedly arranged between the support plates 307. The sealing gasket 1 306 and the sealing gasket 2 308 are both made of rubber. The sealing gasket 1 306 and the sealing gasket 2 308 are filled with water. The support plate 307 is made of spring steel. The inclination angle of the support plate 307 is greater than the inclination angle of the through hole 303. The water in the sealing gasket 1 306 and the sealing gasket 2 308 can prevent the support plate 307 from accidentally sliding out due to being unable to withstand the water pressure, and can also prevent the sealing gasket 2 308 from shrinking inward when the ejection column 304 is ejected, thereby causing water leakage.

[0030] The working principle and use process of the present invention are as follows: during the processing of geomembrane, when the temperature of the geomembrane changes, the water pumps and thermostat components 205 on both sides will play a corresponding role; if the temperature of the geomembrane is too high, the water pump and thermostat component 205 on one side will pump cold water into the pressure roller 201. Since there is a large temperature difference between the cold water and the high-temperature geomembrane, heat conduction can be accelerated, thereby effectively preventing the geomembrane temperature from being too high; and when the temperature of the geomembrane is too low, the water pump and thermostat component 205 on the other side will start to pump hot water into the pressure roller 201; when the hot water is pumped in, the hot water first enters through the bellows 211 , pushing the piston 207 to move to the other side, so that the sealing plug 210 gradually moves away from the connecting pipe 209, and the hot water can smoothly enter the pressing roller 201; as the hot water is continuously pumped in, the piston 207 will continue to move to the other side, squeezing out the original cold water in the pressing roller 201; until the piston 207 is completely moved to the other end, at this time the pressing roller 201 is full of hot water, and the temperature of the pressing roller 201 is quickly increased; if the temperature does not fluctuate greatly, the water inside the pressing roller 201 will start to circulate to maintain a relatively stable temperature environment, ensure that the temperature during the geomembrane processing is appropriate, and ensure the processing quality and efficiency; In the processing of geomembrane, the flow of the water outlet pipe 204 can be adjusted by means of the valve 206, thereby changing the pressure inside the pressure roller 201; when the pressure inside the pressure roller 201 gradually increases, the pressure generated will act on the top column 304 to push it outward; in this way, the protruding top column 304 can press out a corresponding pit on the surface of the geomembrane; in the process of the top column 304 being pushed out, the water inside the pressure roller 201 will mainly act on the pressure column 305, and cooperate with the sealing pad 306 to jointly push the top column 304 outward. Ejection; as the ejector column 304 continues to move outward, the support plate 307 will bend toward the middle position under the influence of the second through hole 303; such a structural design allows the ejector column 304 to return to its original position by utilizing the elasticity of the support plate 307 when the water pressure inside the pressure roller 201 decreases; and in this process, the sealing gasket 1 306 will collapse toward the middle under the dual effects of pressure and the support plate 307; at the same time, the sealing gasket 2 308 will expand toward the outside under the action of the water inside the pressure roller 201.
