Description

Technical Field

[0001] This utility model relates to the technical field of extrusion molding machines for tote bags, and more particularly to extrusion molding machines for tote bags. Background Technology

[0002] A tote bag extrusion molding machine is a device that melts and molds plastic granules into tote bags. It mainly includes an extrusion blow molding machine and a molding machine. The plastic granules are stirred evenly and fed into the extrusion blow molding machine to be blown into a film. The sleeve molding machine seals and cuts the film into tote bags.

[0003] The inventors discovered during routine use of an extrusion molding machine for tote bags that, when using an extrusion blow molding machine for blow molding, the film needs to be blown into shape with hot air, which makes it inconvenient to cool the blown film. This requires a higher cooling rack for cooling. If the cooling rack is too low, the film may stick together, making it impossible to make tote bags, thus causing problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an extrusion molding machine for tote bags.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an extrusion molding machine for tote bags, comprising an extruder, a cooling rack, and a molding machine. One end of the extruder is fixedly connected to an outlet, and an air duct is provided at the top of the outlet. A cutter is provided at the top of the molding machine. A cooling rack is provided on the side of the extruder, and a take-up roller is provided on the side of the cooling rack. A cooling device is provided on the surface of the cooling rack. The cooling device includes a rectangular plate fixedly connected to the side of the cooling rack, an air ring fixedly connected to the side of the rectangular plate, an air pump fixedly connected to the bottom of the air ring, and a through groove opened on the inner wall of the air ring.

[0006] The effect achieved by the above components is as follows: under the action of the air pump, the air ring can blow out cold air, thereby achieving the function of cooling the film. When it is necessary to form plastic granules, the plastic granules are put into the inside of the feed port, the extruder is started, so that the plastic granules melt and flow out through the outlet. The molten plastic is pulled upward, the air duct is started, so that the plastic is blown into a film. The film is placed on the surface of the cooling rack. After cooling, it is wound up by the winding roller. The wound film is placed in the forming machine and cut into a tote bag by the cutter.

[0007] Preferably, the air ring is rotatably connected to an adjusting ring, and the adjusting ring has a through groove on its side.

[0008] The effect achieved by the above components is that, under the action of the adjusting ring, the size of the through groove can be adjusted, thereby adjusting the wind speed and avoiding the phenomenon of membrane deformation caused by excessive wind speed.

[0009] Preferably, the inner wall of the air ring is provided with a sliding groove, and a locking block is fixedly connected to the side of the adjusting ring.

[0010] The effect achieved by the above components is that, under the action of the locking block, the adjusting ring will not slip out of the inside of the air ring, thereby achieving the function of limiting the position.

[0011] Preferably, a rectangular plate is fixedly connected to the top of the air ring, a circular groove is provided on the side of the adjusting ring, and a locking rod is inserted into the side of the rectangular plate, with the locking rod inserted into the interior of the circular groove.

[0012] The aforementioned components achieve the following effects: Under the action of the locking rod and the circular groove, the adjusting ring can be fixed after being adjusted to a suitable position. When cooling of the membrane is required, the air pump is started, allowing gas to enter the interior of the air ring and then be ejected through the through-slot. If the gas volume needs to be adjusted, the locking rod is pulled out from the interior of the circular groove, and the adjusting ring is rotated by hand, causing the through-slots on the surface of the adjusting ring to alternate with the through-slots on the inner wall of the air ring, thereby adjusting the wind speed. Under the action of the locking block, the adjusting ring will not slip out of the interior of the air ring, thus achieving the limiting function. When the adjusting ring is adjusted to a suitable angle, the locking rod is inserted into the interior of the circular groove, thereby achieving the fixing function and thus achieving the cooling effect of the membrane.

[0013] Preferably, the cooling rack is provided with a leveling device on its side, the leveling device including a groove formed on the top of the cooling rack, a roller rotatably connected inside the groove, and a leveling roller provided on the side of the cooling rack.

[0014] The effect achieved by the above components is that, under the action of the leveling roller and the roller shaft, the cooled film can be leveled, avoiding the phenomenon of film wrinkling.

[0015] Preferably, the cooling rack has a rectangular groove on its side, a threaded rod is rotatably connected to the inner wall of the rectangular groove, a slider is threadedly connected to the surface of the threaded rod, and a leveling roller is rotatably connected to the side of the slider.

[0016] The effect achieved by the above components is that, under the action of the threaded rod, the leveling roller can be adjusted, thereby adapting to films of different thicknesses.

[0017] Preferably, a pad, which is a rubber plate, is fixedly connected to the top of the slider.

[0018] The effect achieved by the above components is that, under the action of the pad, the slider will not directly hit the inner wall of the rectangular groove, thus avoiding the phenomenon of slider deformation.

[0019] Preferably, the cooling rack has a screw threadedly connected to its side, with one end of the screw abutting against the surface of the threaded rod.

[0020] The aforementioned components achieve the following effects: the screws fix the position of the threaded rod, thus achieving a fixing function. When leveling the blown film, the screws are unscrewed, and the threaded rod is rotated by hand, causing the slider to move the leveling roller towards the roller position, thus adapting to films of different thicknesses. The pad prevents the slider from directly impacting the inner wall of the rectangular groove, avoiding slider deformation. After the leveling roller moves to the appropriate position, the screws are screwed into the cooling rack, causing one end of the screw to press against the surface of the threaded rod for fixing, thereby achieving the effect of leveling the film.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a cooling device is installed. When cooling of the film is required, the air pump is activated, allowing gas to enter the interior of the air ring and then be ejected through the through-groove. If the gas volume needs to be adjusted, the locking rod is pulled out from the interior of the circular groove, and the adjusting ring is rotated by hand. This causes the through-groove on the surface of the adjusting ring to alternate with the through-groove on the inner wall of the air ring, thereby adjusting the wind speed. Under the action of the locking block, the adjusting ring will not slip out of the interior of the air ring, thus achieving a limiting function. When the adjusting ring is adjusted to the appropriate angle, the locking rod is inserted into the interior of the circular groove, thereby achieving a fixing function and thus achieving the cooling effect of the film. This solves the problem that extruded films are inconvenient to cool. Attached Figure Description

[0032] Working principle: When the blown film needs to be leveled, screw 35 is unscrewed, and threaded rod 32 is turned by hand, causing the slider to move the leveling roller 33 to the position of roller 34. This can accommodate films of different thicknesses. With the help of the pad, the slider will not directly hit the inner wall of the rectangular groove 31, avoiding the deformation of the slider. After the leveling roller 33 moves to the appropriate position, screw 35 is screwed into the interior of the cooling rack 5, so that one end of screw 35 abuts against the surface of threaded rod 32 for fixation, thereby achieving the effect of leveling the film.
