Description

Technical Field

[0001] The invention relates to the technical field of umbrella cloth production, in particular to a polypropylene umbrella cloth casting production line. Background Art

[0002] The polypropylene umbrella cloth casting production line is a device for processing and manufacturing plastic film. The polypropylene umbrella cloth production line uses a casting device to press and extend rubber or plastic into a film of a certain thickness and surface shape at a certain temperature, and then performs trimming, corona, winding and other treatments on the film in turn. The existing polypropylene umbrella cloth casting production line uses a winder to wind the produced film. When the traditional winding mechanism is winding, the driving mechanism drives a material roller to rotate to realize the winding action. When the material roller is full, it is necessary to change the roll, the umbrella cloth needs to be divided, and the empty material roller is replaced on the winder. In order to ensure that the end of the umbrella cloth can be fixed on the empty material roller to achieve smooth winding, double-sided tape is often wound on the material roller. The traditional winding mechanism cannot realize automatic roll change. The production line needs to be stopped when changing the roll. The cutting and gluing processes need to be completed manually, so the traditional winding mechanism cannot guarantee the high-efficiency production of the production line, and the trimming mechanism used in the existing polypropylene umbrella cloth casting production line will produce a lot of waste edge materials, which will cause great waste if not recycled.

[0018] (2) The trimming device of the polypropylene umbrella cloth casting production line of the present invention moves the blade in the blade slot through the first knob bolt, and squeezes the blade through the trapezoidal rubber pad, so that the static friction resistance of the blade is increased, thereby ensuring the stability of the blade and facilitating the slow extension of the blade, so that the user can adjust the extension length according to actual conditions, so that the umbrella cloth can still be extended after being tightened, and the extension length is easier to adjust; the slider moves along the hexagonal prism, so that the cutting assembly is more stable after installation, and the cut edge material is guided out of the winding sleeve through the split roller, so that the cut edge material can be conveniently collected and recycled, reducing the time cost and labor cost of edge material recycling; a smoothing mechanism is provided, and the worm wheel and the smoothing sheet are driven to rotate through the rotation of the power shaft and the worm sleeve, thereby smoothing the umbrella cloth inserted into the tightening roller, and because the worm sleeve rotates in the opposite direction, the smoothing is smoothed from the middle to the two sides, so that the smoothing of the umbrella cloth is more sufficient and stable.

[0019] (3) The corona device of the polypropylene umbrella cloth casting production line of the present invention can keep the exhaust duct flat through the support column, the limit ring, the circular ring, the fastening screw, the exhaust duct support plate, the groove and the fluorescent warning sign, thereby reducing the wrinkles of the exhaust duct and facilitating the normal exhaust of the exhaust duct. Moreover, the fluorescent warning sign can be used to warn the staff and prevent the electric shock between the staff and the device body. The concave connecting block, the L-shaped connecting block, the notch, the roller, the circular hole and the extrusion screw can facilitate the installation between the device body and the concave connecting block, reducing the installation difficulty between the device body and the concave connecting block.

[0020] (4) The winding device of the polypropylene umbrella cloth casting production line of the present invention moves an empty material roll to the winding station through the upper roller mechanism. While the roll is being raised, the roller-type gluing mechanism glues the material roll. The glued material roll is pressed onto the large roller under the action of the positioning rod for winding. When the material roll is full, the positioning rod transfers the cloth roll to the residual material winding mechanism under the action of the material transfer cylinder. The U-shaped groove at the upper end of the positioning rod is tilted, and the cloth roll rolls from the U-shaped groove to the residual material winding mechanism. The positioning rod is reset, and the next empty material roll after gluing is pressed onto the large roller under the action of the positioning rod. The lifting cutter mechanism rises to cut the cloth, and the next round of winding begins. The winding device for the production of plastic umbrella cloth of the present invention can realize automatic roll changing, cutting and gluing processes. When it is used in the umbrella cloth production line, there is no need to stop the machine to perform the above processes, which is conducive to high-speed continuous operation of the production line and can improve the production efficiency of the umbrella cloth production line.

[0055] A moving rod 1111 is arranged in the middle of the inner wall of the slide groove 110, and the outer diameter of the moving rod 1111 is equal to the inner diameter of the slide groove 110. The moving rod 1111 is located inside the slide groove 110, and can limit and fix the moving rod 1111 to prevent the moving rod 1111 from moving. A knife holder 1112 is welded in the middle of the top of the moving rod 1111, and a bamboo knife 1113 is embedded in the middle of the top of the knife holder 1112. The number of moving rods 1111 is set to three, and two connected The moving rods 1111 are connected by connecting rods 1114, and the moving rods 1111 are used to drive the three bamboo knives 1113 to move, so that the three bamboo knives 1113 are respectively fitted with the guide roller 102, the pressure roller 103 and the drainage roller 104, so as to clean the surfaces of the guide roller 102, the pressure roller 103 and the drainage roller 104. Connecting rods 1114 are welded to both sides of one end face of the moving rod 1111, and the middle part of the bottom end of the connecting rod 1114 is connected to a cylinder 1115.

[0057] Working principle and use process of the casting device 1: the film enters the surface of the pressure roller 103 along the drainage roller 104, and the film on the surface of the pressure roller 103 enters the surface of the guide roller 102, thereby completing the installation of the film and the guide roller 102, the pressure roller 103 and the drainage roller 104. Then, the transparent plastic plate 108 is rotated. After the transparent plastic plate 108 rotates, when one side of the bottom of the transparent plastic plate 108 is in contact with the support plate 107, the bottom end surface of the other end of the transparent plastic plate 108 is in contact with the suction cup 109 at the top of the support rod 105, and then the transparent plastic plate 108 is pressed, so that The transparent plastic plate 108 and the suction cup 109 are fixed to each other, and the transparent plastic plate 108 can be used to protect the surfaces of the guide roller 102, the pressure roller 103 and the drainage roller 104, so as to prevent external dust from dripping onto the surfaces of the guide roller 102, the pressure roller 103 and the drainage roller 104, thereby ensuring the cleanliness of the surfaces of the guide roller 102, the pressure roller 103 and the drainage roller 104, and at the same time, preventing the surfaces of the guide roller 102, the pressure roller 103 and the drainage roller 104 from being scratched, so that the guide roller 102, the pressure roller 103 and the drainage roller 104 can be used normally;

[0058] Then, the oil return pipes 112 of the guide roller 102, the pressure roller 103 and the guide roller 104 are respectively placed into the semicircular ring 115 of the fixed block 113, and then the screw 116 is rotated to make the fixed block 113 and the movable block 114 fit together, so that the oil return pipe 112 is fixed between the two semicircular rings 115, which can limit the oil return pipe 112 to prevent the oil return pipe 112 from shaking, thereby making the installation of the oil return pipe 112 more stable;

[0059] Finally, the film moves along the surfaces of the guide roller 102, the pressure roller 103 and the drainage roller 104, thereby completing the casting of the umbrella cloth 5. When the device is no longer in use, the cylinder 1115 drives the connecting rod 1114 to move, and the connecting rod 1114 drives the three moving rods 1111 to move along the inside of the slide 110 respectively.

[0062] A plurality of sliders 2061 are slidably connected to the middle of the hexagonal prism 205. A hexagonal hole is formed through one end of the slider 2061. The outer edge of the cross section of the hexagonal prism 205 fits with the inner edge of the cross section of the hexagonal hole to prevent the slider 2061 from turning over.
