[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the utility model.

[0026] like Figures 1 to 9 As shown, this embodiment discloses a film laying device for internal corners, comprising a film pressing member 1 and a hand piece 4, wherein the film pressing member 1 is connected to the hand piece 4;

[0027] The die-casting member 1 is in the shape of a horizontally placed triangular prism, and the triangular faces of the triangular prism are composed of a vertical side surface 11, a bottom surface 12, and an oblique side surface 13. The vertical side surface 11 and the bottom surface 12 are in a vertical state and intersect to form a 90° edge 14. A first extrusion member 2 is arranged on the vertical side surface 11, and a second extrusion member 3 is arranged on the bottom surface 12. Both the first extrusion member 2 and the second extrusion member 3 are long strip structures, and both the first extrusion member 2 and the second extrusion member 3 are arranged in an inclined state. One end of the first extrusion member 2 and the second extrusion member 3 in the length direction is arranged relatively close to the 90° edge 14, and the other end of the first extrusion member 2 and the second extrusion member 3 in the length direction is arranged relatively far away from the 90° edge 14; a handpiece is connected to the oblique side surface 13.

[0028] The first extrusion piece and the second extrusion piece are designed to be inclined. When performing the film laying operation, the ends of the first extrusion piece and the second extrusion piece close to the 90° edge are oriented toward the direction to be moved during film laying. During the movement of the film pressing piece, the end face of the first extrusion piece can squeeze the wrinkled and puffed HDPE film toward the upper side wall of the landfill body, and the end face of the second extrusion piece can squeeze the wrinkled and puffed HDPE film toward the outside of the bottom end of the landfill body, that is, to squeeze out the excess HDPE film to the outside of the laying area of ​​the inner corner, thereby smoothing the HDPE film, which can make the HDPE film laid more flat, thereby improving the laying effect of the HDPE film.

[0029] The first extrusion piece 2 and the second extrusion piece 3 are both in the shape of rectangular columns. One end of the first extrusion piece 2 extending out of the first accommodating groove 111 and one end of the second extrusion piece 3 extending out of the second accommodating groove 121 have a long side away from the 90° edge 14 in an arc-shaped curved structure.

[0030] When the first extrusion piece and the second extrusion piece smooth out the HDPE film, the side close to the wrinkled and puffed HDPE film is an arc curved structure, which can avoid the HDPE film from being broken when the 90-degree angle is smoothed, and at the same time make the smoothing process smoother, thereby improving the use effect of the utility model.

[0031] A first accommodating groove 111 is provided on the vertical side surface 11, and a first extrusion member 2 and a first spring 22 are provided in the first accommodating groove 111. One end of the first extrusion member 2 in the thickness direction is located in the first accommodating groove 111, and a first spring 22 is provided between the end surface of the end and the inner end surface of the first accommodating groove 111, and the other end of the first extrusion member 2 in the thickness direction extends out of the first accommodating groove 111; when the vertical side surface 11 of the film pressing member 1 abuts against the side wall 7 of the landfill body through the HDPE film 6, the first extrusion member 2 slides into the first accommodating groove 111 along the vertical direction of the vertical side surface 11 and compresses the first spring 22; when the vertical side surface 11 of the film pressing member 1 does not abut against the side wall 7 of the landfill body, one end of the first extrusion member 2 in the thickness direction extends out of the first accommodating groove 111 again under the action of the first spring 22.

[0032] The first accommodating groove 111 is a constricted groove structure, and first limiting protrusions 21 are integrally formed on both sides of the end of the first extrusion member 2 extending into the first accommodating groove 111. The first limiting protrusion 21 abuts against the constricted end wall of the first accommodating groove 111 under the action of the first spring 22.

[0033] The connection structure between the first extrusion piece and the first spring enables the vertical side surface of the film pressing piece to abut against the side wall of the landfill body during the film laying operation, thereby avoiding deviation of the film pressing piece during movement and ensuring the stability of the film pressing piece during movement. At the same time, the first extrusion piece will give the HDPE film a bonding pre-pressure through the elastic force of the first spring, so that the HDPE film can be tightly bonded to the side wall of the landfill body, ensuring that the film laying effect of the landfill body is not affected.

[0034] A second accommodating groove 121 is provided on the bottom surface 12, and a second extrusion piece 3 and a second spring 32 are provided in the second accommodating groove 121. One end of the second extrusion piece 3 in the thickness direction is located in the second accommodating groove 121 and a second spring 32 is provided between the end surface of the end and the inner end surface of the second accommodating groove 121, and the other end of the second extrusion piece 3 in the thickness direction extends out of the second accommodating groove 121; when the bottom surface 12 of the film pressing piece 1 abuts against the bottom end wall 8 of the landfill body through the HDPE film 6, the second extrusion piece 3 slides into the second accommodating groove 121 along the vertical direction of the bottom surface 12 and compresses the second spring 32; when the bottom surface 12 of the film pressing piece 1 does not abut against the bottom end wall 8 of the landfill body, one end of the second extrusion piece 3 in the thickness direction extends out of the second accommodating groove 121 again under the action of the second spring 3.

[0035] The second accommodating groove 121 is a constricted groove structure, and second limiting protrusions 31 are integrally formed on both sides of the end of the second extrusion member 3 extending into the second accommodating groove 121. The second limiting protrusion 31 abuts against the constricted end wall of the second accommodating groove 121 under the action of the second spring 32.

[0036] The connection structure between the second extrusion piece and the second spring allows the bottom surface of the film pressing piece to abut against the bottom end of the landfill body during the film laying operation, thereby avoiding deviation of the film pressing piece during movement and ensuring the stability of the film pressing piece during movement. At the same time, the second extrusion piece will give the HDPE film a bonding pre-pressure through the elastic force of the second spring, so that the HDPE film can be tightly bonded to the bottom end wall of the landfill body, ensuring that the film laying effect of the landfill body is not affected.

[0037] The 90° edge 14 is a chamfered structure, and a plurality of ball grooves 15 are arranged on the 90° edge 14 at equal intervals along the length direction of the 90° edge 14. The ball groove 15 is a constricted structure, and a ball 5 is embedded in the ball groove 15 and the ball 5 can rotate in the ball groove 15. One side outer peripheral surface of the ball 5 extends from the opening position of the ball groove 15 to the outside of the ball groove 15.

[0038] This design allows the ball to contact the 90-degree angle of the inner corner when the film pressing part moves, thereby realizing the HDPE film extrusion and laying operation at the inner corner, while reducing the friction during the movement process, making it easier for people to operate.

[0039] Two connecting ears 16 are provided on the inclined side surface 13 along the length direction of the inclined side surface 13, and a mounting piece 41 is connected to the mounting piece 41 through the two connecting ears 16 pins. The axial direction of the mounting piece 41 is consistent with the length direction of the inclined side surface 13 and the mounting piece 41 is located at the center of the inclined side surface 13. A hand piece 4 is fixedly connected to the mounting piece 41 and the length direction of the hand piece 4 is perpendicular to the axial direction of the mounting piece 41.

[0040] During the film laying process, the hand piece can rotate around the axis of the film pressing piece to achieve a height adjustment effect of the hand piece. It can be rotated to a suitable position according to people's hand-holding height, which improves the hand-holding convenience of construction workers. At the same time, it will not affect the force of the hand piece on the axial direction of the film pressing piece, ensuring that the movement effect of the hand piece on the film pressing piece is not affected, further improving the use effect of the utility model.

[0041] When the utility model is performing the film laying operation, the adhesive surface of the HDPE film (the adhesive surface will not adhere to the wall when it is simply placed on the wall, and a tight adhesive effect can be achieved only after being squeezed hard) is first placed at the inner corner between the bottom end and the side wall of the landfill body, and then the vertical side surface of the film pressing piece is abutted against the side wall of the landfill body at the inner corner through the HDPE film, and the bottom surface of the film pressing piece is abutted against the bottom end wall of the landfill body at the inner corner through the HDPE film. At this time, the 90° edge is located at the 90° angle at the inner corner and the HDPE film is also squeezed to this position, and then, by hand The holding piece enables the film pressing piece to move horizontally along the angle edge of the inner corner. During the movement, the 90° edge on the film pressing piece will squeeze the HDPE film and make it adhere to the 90-degree angle of the inner corner. The first extrusion piece on the vertical side will squeeze the HDPE film onto the side wall of the landfill body, and the second extrusion piece on the bottom will squeeze the HDPE film onto the side wall of the landfill body, finally realizing the laying operation at the inner corner of the landfill body. The whole laying process saves time and labor, reduces the workload of construction workers, effectively improves the film laying efficiency of the landfill body, and brings convenience to the film laying operation of the landfill body.
