Description

Technical Field

[0001] The utility model relates to the technical field of tarpaulin processing, in particular to an edge trimming device used for tarpaulin processing. Background Art

[0002] Tarpaulin is a waterproof material with high strength, good toughness and softness. It is often used as canvas, polyester with polyurethane coating or made into polyethylene plastic. During the processing of tarpaulin, it needs to be cut into corresponding specifications according to requirements. After cutting, the cutting edges are easy to become linear. If the cut tarpaulin is directly rolled up, the linear corners of the tarpaulin may cause the rolling to be untidy.

[0003] To this end, a Chinese patent document with announcement number CN219031180U discloses a tarpaulin edge trimming machine, including a main body, a conveying device, a fixed plate, a roller and a motor, two groups of connecting plates are fixedly installed in mirror image on the upper side of the main body, an installation space that passes through the connecting plates is opened on the upper side of the two groups of connecting plates, a heating plate is fixedly installed on the side of the main body at a position corresponding to the installation space, a mounting plate is arranged inside the installation space at a position corresponding to the heating plate, two groups of slide plates are symmetrically fixedly installed on both sides of the mounting plate and the two groups of slide plates are arranged inside the installation space, and restraint rods are fixedly installed equidistantly inside the installation space and the restraint rods pass through the slide plates.

[0004] It can be seen from the above disclosed content that in the above technical scheme, the heating plate strengthens the heat transmitted to the side of the pressure plate through the heat transfer plate, and at the same time the restraint rod plays a guiding and restraining role on the slide plate. The motor drives the roller to rotate and drive the tarpaulin to be folded up, so that the edges and corners of the tarpaulin are heated and trimmed, avoiding the linear shape of the edges and corners of the tarpaulin which may cause uneven rolling.

[0005] However, in the process of implementing the above technical solution, the inventor needs to pass the tarpaulin between the pressing plate and the heating plate and then pull it to the winding roller before rolling it up. However, under the action of the elastic force generated by the restraint rod, the pressing plate and the heating plate are fitted together, so there is a certain inconvenience when passing the tarpaulin between the pressing plate and the heating plate. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an edge trimming device for tarpaulin processing, which makes it more convenient to insert the tarpaulin between the top pressing plate and the bottom pressing plate by lifting the top pressing plate.

[0008] The utility model is further configured as follows: a mounting seat is provided on the top of the mounting plate, both ends of the rotating shaft are rotatably connected to the mounting frames on both sides, connecting rods are respectively fitted and fixed on both ends of the rotating shaft, and the connecting rod is rotatably connected to the mounting seat at one end away from the rotating shaft.

[0012] The utility model is further configured as follows: the surface of the bottom pressing plate is flush with the surface of the conveyor belt.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By connecting the mounting plate for mounting the top pressure plate to the connecting rod through the mounting seat, when the tarpaulin needs to be passed between the top pressure plate and the bottom pressure plate to complete the preliminary preparation work, the connecting rod can be moved from a low point to a high point as the rotating shaft rotates, thereby achieving the lifting of the top pressure plate.

[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, the utility model discloses an edge-closing device for tarpaulin processing, comprising a conveyor belt 1, a mounting plate 2 and a mounting frame 3 are arranged on both sides of the conveyor belt 1, a top pressing plate 4 is fixed at the bottom of the mounting plate 2, a bottom pressing plate 5 is arranged above the top pressing plate 4, a first heating plate 41 is arranged inside the top pressing plate 4, the first heating plate 41 is used to heat the top pressing plate 4, a rotating shaft 6 is arranged above the mounting seat 21, the rotating shaft 6 drives the top pressing plate 4 to rise and fall by rotating, a winding roller 7 is arranged downstream of the conveyor belt 1, and the winding roller 7 is used to wind and pull the tarpaulin on the conveyor belt 1;

[0021] The structure of lifting and lowering the top pressure plate 4 by rotating the rotating shaft 6 is as follows: a mounting seat 21 is provided on the top of the mounting plate 2, and both ends of the rotating shaft 6 are respectively rotatably connected to the mounting frames 3 on both sides, and connecting rods 8 are respectively fixedly mounted on both ends of the rotating shaft 6, and the connecting rod 8 is located at one end away from the rotating shaft 6 and is rotatably connected to the mounting seat 21. By connecting the mounting plate 2 on which the top pressure plate 4 is installed with the connecting rod 8 through the mounting seat 21, when it is necessary to pass the tarpaulin between the top pressure plate 4 and the bottom pressure plate 5 to complete the preliminary preparation work, by rotating the rotating shaft 6, the connecting rod 8 can move from a low point to a high point as the rotating shaft 6 rotates, thereby realizing the lifting of the top pressure plate 4, making it more convenient to pass the tarpaulin between the top pressure plate 4 and the bottom pressure plate 5;

[0022] In addition, it should be noted that since the commonly used heating plate is mainly composed of a heating tube and a cast plate laid on the outside of the heating tube, and the cast plate is made of a metal with toughness and excellent thermal conductivity, the cast plate will have a certain curvature. In this embodiment, the top pressure plate 4 and the bottom pressure plate 5 are heated respectively by heat conduction through the built-in heating plate, and the setting of the top pressure plate 4 and the bottom pressure plate 5 can ensure that they fit the surface of the tarpaulin, thereby preventing the heating plate from directly contacting the surface of the tarpaulin due to the curvature of the cast plate, resulting in insufficient close fit with the surface of the tarpaulin.

[0023] In this embodiment, one end of the rotating shaft 6 is further extended outward as a connecting end 61, and a locking disk 9 is fixedly mounted on the outer periphery of the connecting end 61. The locking disk 9 is provided with a first locking hole 91 that penetrates therethrough. There are multiple first locking holes 91 that are evenly distributed around the circumference. The mounting frame 3 is provided with a second locking hole 31 that is opposite to the first locking hole 91. The first locking hole 91 and the second locking hole 31 are limited by a latch 10. By providing the first locking hole 91 and the second locking hole 31, after the top pressure plate 4 is lifted to a suitable height, the latch 10 can be inserted into the first locking hole 91 and the second locking hole 31 to limit the locking disk 9, thereby locking the rotating shaft 6. In this way, when the tarpaulin is passed between the top pressure plate 4 and the bottom pressure plate 5, there is no need to continuously apply force to the rotating shaft 6, thereby improving the overall convenience of use.

[0024] In this embodiment, a support rod 11 extending toward the support plate is further provided on the mounting seat 21, and an arc-shaped support opening 32 is provided on the mounting frame 3. The arc-shaped support opening 32 is adapted to the rotation path of the support rod 11, and the support rod 11 is coupled to the arc-shaped support opening 32. During the rotation of the rotating shaft 6, as the mounting plate 2 is lifted, the support rod 11 can slide along the path of the arc-shaped support opening 32. The support of the support rod 11 by the arc-shaped support opening 32 can reduce the load on the connecting rod 8, thereby improving the stability during long-term use.

[0025] In this embodiment, installation space is further provided on both sides of the conveyor belt 1, and the bottom pressing plate 5 is fixed in the installation space. A second heating plate 51 is provided in the bottom pressing plate 5, and the second heating plate 51 is used to heat the bottom pressing plate 5. Through the setting of the installation space, the surface of the bottom pressing plate 5 can be flush with the surface of the conveyor belt 1, thereby ensuring that the tarpaulin can contact the surface of the conveyor belt 1, thereby ensuring the stability of the tarpaulin transportation, and by arranging the second heating plate 51 in the bottom pressing plate 5, the top pressing plate 4 and the bottom pressing plate 5 can heat the upper and lower surfaces of the tarpaulin respectively, thereby improving the edge sealing efficiency of the tarpaulin cutting edge.

[0026] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
