Description

Technical Field

[0001] This utility model relates to the field of geotechnical construction equipment technology, and in particular to a geomembrane heat sealing and pressing machine. Background Technology

[0002] Geomembrane is a waterproof barrier material made from high molecular polymers. It has excellent seepage prevention and isolation properties and is widely used in water conservancy projects, landfills, artificial lakes and other projects to prevent liquid leakage and gas evaporation. In practical engineering applications, geomembranes need to be spliced ​​into large-area seepage prevention structures, which requires the use of a heat sealing edge pressing machine. A heat sealing edge pressing machine is a device used to heat and melt the edges of two or more geomembranes and apply pressure to firmly bond them together to ensure that the splice has good sealing and strength.

[0003] The existing geomembrane heat sealing and pressing machine has the following shortcomings:

[0004] Existing heat-sealing edge-pressing machines typically cannot flexibly adjust the position of the geomembrane during the heat-sealing process. Due to the lack of a structure that can precisely control the geomembrane's insertion position, it is difficult to ensure the accuracy of the splicing position when splicing geomembranes of different specifications, resulting in splicing deviations and affecting the overall seepage prevention effect. At the same time, existing devices cannot adjust the edge-pressing pressure according to the material and thickness of the geomembrane. Because its edge-pressing pressure adjustment method is singular and imprecise, it cannot adapt to different working conditions. Problems such as easy damage when pressing thinner geomembranes and weak adhesion when pressing thicker geomembranes are encountered. Summary of the Invention

[0005] This utility model proposes a geomembrane heat-sealing edge pressing machine. By cooperating with a sliding baffle and a positioning component, the machine can precisely control the insertion distance of the geomembrane in the connecting groove, allowing the geomembrane to adhere to the double-sided heating plate, accurately adjust the splicing position, and improve the heat-sealing quality. With the cooperation of a tightening spring and a limiting baffle, the pressing pressure can be flexibly and accurately adjusted to adapt to different geomembranes, avoid damage or poor adhesion, and improve the applicability of the pressing process, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a geomembrane heat sealing and pressing machine, including a heating device, with support frames fixedly connected to the bottom front and rear sides of the heating device, and pressing devices fixedly connected to the upper and lower ends of the right side of the heating device.

[0007] The heating device includes an S-shaped bracket, which is fixedly connected to the top of a support frame. Connecting grooves are provided above the rear surface and below the front surface of the heating device. A double-sided heating plate is fixedly connected to the middle of the heating device. The upper and lower sides of the double-sided heating plate respectively extend into the middle of the two connecting grooves. A knob is provided below the rear surface and above the front surface of the heating device. A transmission screw is fixedly connected to the side of the knob closest to the S-shaped bracket. The outer surface of the transmission screw is threaded to the S-shaped bracket. The end of the transmission screw away from the knob extends into the interior of the connecting groove and is fixedly connected to a sliding baffle. The outer surface of the sliding baffle is slidably connected to the inner surface of the connecting groove. Positioning components are provided in the middle of the upper and lower sides of the heating device.

[0008] Preferably, the positioning component includes threaded sleeves, and two threaded sleeves are respectively rotatably engaged in the middle of the upper and lower sides of the heating device. The inner surface of the threaded sleeve is threaded with a threaded column on the side near the connecting groove. The end of the threaded column away from the threaded sleeve extends into the interior of the connecting groove and is fixedly connected to a push plate. The push plate is rotatably connected to limit wheels on both the left and right sides on the side away from the threaded column.

[0009] Preferably, a handle is fixedly connected to the end of the threaded sleeve away from the threaded post, and limiting slide pins are fixedly connected to both the left and right sides of the push plate near the threaded post. Two limiting slide grooves are opened on the upper and lower sides of the S-shaped bracket, and the outer surface of the limiting slide pin is slidably connected to the inner surface of the limiting slide groove.

[0010] Preferably, the pressing device includes a connecting plate, two connecting plates are respectively fixedly connected to the upper and lower ends of the right side of the heating device, four vertically penetrating sliding sleeves are slidably connected to the right side of the connecting plate, telescopic sliding columns are slidably inserted into the bottom end of the inner surface of the sliding sleeves, and a pressing plate is fixedly connected to the bottom end of the four telescopic sliding columns. Pressing wheels are rotatably connected to the left and right sides of the bottom of the pressing plate.

[0011] Preferably, a tightening spring is fixedly connected to the top center of the extrusion plate, and a limiting baffle is fixedly connected to the upper and lower ends of the four sliding sleeve columns. The top end of the tightening spring is fixedly connected to the lower surface of the bottom limiting baffle.

[0012] Preferably, a second handle is rotatably connected to the upper surface of the top limiting baffle, and a lifting screw is fixedly connected to the bottom of the second handle. The lifting screw is movably connected to the middle of the opposite surfaces of the two limiting baffles and is threadedly connected to the connecting plate.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. In this utility model, through the cooperation of the knob, transmission screw, sliding baffle, and positioning component, two geomembranes to be spliced ​​slide from the upper and lower connecting grooves of the S-shaped bracket. When the knob is turned, the knob drives the transmission screw to rotate. Since the transmission screw is threadedly connected to the S-shaped bracket, the transmission screw drives the sliding baffle to slide in the connecting groove, thereby accurately controlling the distance at which the geomembrane is inserted in the connecting groove. At the same time, turning the handle causes the threaded sleeve to rotate. The threaded sleeve and the threaded column are threadedly connected, thereby pushing the threaded column to drive the push plate and the limiting wheel to move, so that the geomembrane is tightly attached to the surface of the double-sided heating plate. In this way, the bonding position between the geomembranes can be precisely adjusted according to the splicing requirements of different geomembranes, ensuring that the splicing position is accurate, effectively improving the heat sealing quality, and avoiding the impact of splicing deviation on the seepage prevention effect.

[0015] 2. In this utility model, through the cooperation between the tightening spring, the second handle, the lifting screw, and the limiting baffle, the tightening spring pushes the extrusion plate, thereby causing the pressing wheel to apply pressure to the bonding part of the geomembrane. When the second handle is turned, the second handle drives the lifting screw to rotate. Since the lifting screw is threadedly connected to the connecting plate and movably connected between the two limiting baffles, the rotation of the lifting screw will cause the limiting baffles to slide up and down, thereby adjusting the tightening force of the tightening spring on the extrusion plate and the pressing wheel. In this way, the pressing pressure can be flexibly and accurately adjusted according to the geomembrane of different materials and thicknesses, avoiding damage when pressing thinner geomembranes and weak bonding when pressing thicker geomembranes, thus significantly improving the applicability and quality of pressing.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution: including a heating device 1, with support frames 2 fixedly connected to the bottom front and rear sides of the heating device 1, and pressing devices 3 fixedly connected to the upper and lower ends of the right side of the heating device 1. The heating device 1 includes an S-shaped bracket 11, which is fixedly connected to the top of the support frame 2. Connecting grooves are provided above the rear surface and below the front surface of the heating device 1. A double-sided heating plate 12 is fixedly connected to the middle of the heating device 1. The upper and lower sides of the double-sided heating plate 12 respectively penetrate into the middle of the two connecting grooves. A knob 13 is provided below the rear surface and above the front surface of the heating device 1. A transmission screw 14 is fixedly connected to the side of the knob 13 near the S-shaped bracket 11. The outer surface of the transmission screw 14 is threaded to the S-shaped bracket 11. The end of the transmission screw 14 away from the knob 13 penetrates into the interior of the connecting groove and is fixedly connected to a sliding baffle 15. The outer surface of the sliding baffle 15 is slidably connected to the inner surface of the connecting groove. A positioning component 16 is provided in the middle of the upper and lower sides of the heating device 1.

[0024] The overall effect achieved by Embodiment 1 is as follows: it provides the overall structure of the heat-sealing edge pressing machine, which enables the geomembrane to be transported in the connecting groove of the S-shaped support 11. The double-sided heating plate 12 can heat the geomembrane. Through the cooperation of the knob 13, the transmission screw 14 and the sliding baffle 15, the basic conditions for adjusting the heat-sealing position of the geomembrane are initially met, which provides support for subsequent precise positioning and heat-sealing operations.

[0025] Example 2: As Figure 3 As shown, this utility model provides a technical solution: the positioning component 16 includes a threaded sleeve 161, two threaded sleeves 161 are respectively rotatably engaged in the middle of the upper and lower sides of the heating device 1, the inner surface of the threaded sleeve 161 is threadedly connected to a threaded column 162 on the side near the connecting groove, the end of the threaded column 162 away from the threaded sleeve 161 passes through the interior of the connecting groove and is fixedly connected to a push plate 163, the push plate 163 is rotatably connected to the left and right sides on the side away from the threaded column 162, the end of the threaded sleeve 161 away from the threaded column 162 is fixedly connected to a handle 165, the push plate 163 is fixedly connected to the left and right sides on the side near the threaded column 162, and the S-shaped bracket 11 has two limiting grooves 167 on the upper and lower sides, the outer surface of the limiting groove 166 is slidably connected to the inner surface of the limiting groove 167;

[0026] The effect achieved by the entire embodiment 2 is as follows: rotating the handle 165 drives the threaded sleeve 161 to rotate. Since the threaded sleeve 161 is threadedly connected to the threaded column 162, the threaded column 162 will drive the push plate 163 and the limiting wheel 164 to move. The limiting wheel 164 can push the geomembrane to fit tightly against the double-sided heating plate 12. At the same time, the limiting slide column 166 slides in the limiting slide groove 167 to ensure the stability of the push plate 163's movement, thereby further and more accurately adjusting the bonding position of the geomembrane and the double-sided heating plate 12 and improving the heat sealing effect.

[0027] Example 3: As Figure 4As shown, this utility model provides a technical solution: the pressing device 3 includes a connecting plate 31, two connecting plates 31 are respectively fixedly connected to the upper and lower ends of the right side of the heating device 1, four vertically penetrating sliding sleeves 32 are slidably connected to the right side of the connecting plate 31, telescopic sliding columns 33 are slidably inserted into the bottom end of the inner surface of the sliding sleeves 32, a pressing plate 34 is fixedly connected to the bottom end of the four telescopic sliding columns 33, a pressing wheel 35 is rotatably connected to the left and right sides of the bottom of the pressing plate 34, a top pressing spring 36 is fixedly connected to the center of the top of the pressing plate 34, a limiting baffle 37 is fixedly connected to the upper and lower ends of the four sliding sleeves 32, the top end of the top pressing spring 36 is fixedly connected to the lower surface of the bottom limiting baffle 37, a handle 38 is rotatably connected to the upper surface of the top limiting baffle 37, a lifting screw 39 is fixedly connected to the bottom of the handle 38, the lifting screw 39 is movably connected to the middle of the opposite surfaces of the two limiting baffles 37 and threadedly connected to the connecting plate 31;

[0028] The effect achieved by the entire embodiment 3 is as follows: the top spring 36 pushes the extrusion plate 34, so that the pressure roller 35 applies pressure to the heated geomembrane bonding part to realize the edge pressing operation. The handle 38 is turned to drive the lifting screw 39 to rotate. Since the lifting screw 39 is threadedly connected to the connecting plate 31 and connected to the limiting baffle 37, the position of the limiting baffle 37 can be adjusted, thereby changing the top spring 36's top force on the extrusion plate 34 and the pressure roller 35 to adapt to the edge pressing requirements of geomembranes of different materials and thicknesses, and improve the applicability and quality of edge pressing.

[0029] The working principle of the entire equipment is as follows: When using the geomembrane heat sealing and pressing machine, firstly, the two pieces of geomembrane to be spliced ​​are passed through the connecting grooves on the upper and lower sides of the S-shaped bracket 11. According to the specifications of the geomembrane and the splicing requirements, the knob 13 on the lower rear surface and the upper front surface of the heating device 1 is rotated. The knob 13 drives the transmission screw 14 to rotate. Since the transmission screw 14 is threadedly connected to the S-shaped bracket 11, the transmission screw 14 will drive the sliding baffle 15 to slide in the connecting groove, thereby precisely controlling the geomembrane to be stuck in the connecting groove. The distance is determined to establish the splicing position between geomembranes. Then, the handle 165 in the positioning assembly 16 is rotated. The handle 165 drives the threaded sleeve 161 to rotate, and the threaded sleeve 161 is threadedly connected to the threaded post 162. This causes the threaded post 162 to move the push plate 163 and the limiting wheel 164. The limiting wheel 164 pushes the geomembrane towards the double-sided heating plate 12, ensuring a tight fit between the geomembrane and the surface of the double-sided heating plate 12. At this point, the double-sided heating plate 12 is activated to heat the splicing area of ​​the geomembrane, causing the surface of the geomembrane to... After the surface melts and heating is complete, the edge pressing device 3 starts working. The top spring 36 pushes the extrusion plate 34 downward. The pressing wheel 35 at the bottom of the extrusion plate 34 applies pressure to the heated geomembrane bonding area, making the two geomembranes firmly bonded. If it is necessary to adjust the edge pressing pressure, the handle 38 on the top limit baffle 37 can be rotated. The handle 38 drives the lifting screw 39 to rotate. The lifting screw 39 is threadedly connected to the connecting plate 31 and connected to the limit baffle 37. The position of the limit baffle 37 can be adjusted by rotating the lifting screw 39. The clamping force of the top spring 36 on the extrusion plate 34 and the clamping wheel 35 is adjusted to meet the edge pressing requirements of geomembranes of different materials and thicknesses. During the entire operation, the limiting slide column 166 in the positioning component 16 slides in the limiting slide groove 167 on the S-shaped bracket 11 to ensure the smooth movement of the push plate 163. The sliding sleeve column 32 and the telescopic slide column 33 in the edge pressing device 3 cooperate to ensure that the extrusion plate 34 can move up and down stably, realize precise heat sealing edge pressing operation, and improve the quality and efficiency of geomembrane splicing.
