DETAILED DESCRIPTION

[0019] 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and are added with a variety of organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials. After adding the corresponding organic solvents, they are heated at high temperature and blow-molded, extruded, or injection-molded through plastic molds to form plastic containers. Therefore, the plastic milk bottle forming device is needed. Before using this equipment, you first need to check whether the connections between the components are tight, especially the connections between the templates, to avoid affecting the use. During use, at least one staff member is required to operate it, and employees need to be avoided from being scalded during use.

[0021] like Figure 1 - Figure 3 As shown, the utility model provides a technical solution: a plastic milk bottle molding device, including a base plate 1, a shell 2 is fixedly connected to the top of the base plate 1, a feeding mechanism 3 is arranged on the top of the shell 2, the feeding mechanism 3 includes a feeding box 301, a spiral plate 302 is fixedly connected to the bottom inner wall of the feeding box 301, a hot melt blow molding machine 4 is installed on one side of the top of the shell 2, a molding mechanism 5 is arranged on one side of the top of the base plate 1, the molding mechanism 5 includes a linear slide rail 501, the linear slide rail 501 is connected to the base plate 1, and a slider 502 is slidably connected to the top of the linear slide rail 501.

[0022] It should be noted that during use, the plastic particles are first placed in the feeding box 301 of the feeding mechanism 3, and are transported to the hot melt blow molding machine 4 through the spiral plate 302. Then the hot melt blow molding machine 4 blows the plastic into the molding mechanism 5 under the action of high pressure, which is convenient for operation and observation of the entire molding process. The design of the spiral plate 302 enables the plastic particles to be transported evenly and stably, avoiding interruptions or uneven feeding and improving production efficiency.

[0023] like Figure 2 As shown, a filter cartridge 303 is fixedly connected to the center of the bottom of the loading box 301, a through hole is opened through the top of the loading box 301, a feed funnel 304 is fixedly connected in the through hole, a slot is opened on one side of the bottom of the loading box 301, a discharge pipe 305 is fixedly connected in the slot, one end of the discharge pipe 305 is connected to the hot melt blow molding machine 4, and a waste pipe 306 is fixedly connected to the center of the bottom of the loading box 301.

[0024] It should be noted that during use, the plastic particles first enter the loading box 301 through the feed funnel 304. In this process, the plastic particles with smaller particle sizes are discharged through the filter cylinder 303 and the waste pipe 306, and the particles with larger particle sizes are transported to the bottom of the loading box 301 through the spiral plate 302, and enter the hot melt blow molding machine 4 through the discharge pipe 305. The use of the spiral plate 302 as a conveying device can accurately control the feed amount and speed of the plastic particles to ensure the material quality and consistency of each bottle, and can also effectively filter out unnecessary impurities and particles, thereby improving the quality and purity of the finished milk bottles.

[0025] like Figure 3 - Figure 4 As shown, a fixed plate 503 is fixedly connected to one side of the top of the slider 502, a fixed mold 504 is installed on one side of the fixed plate 503, a movable mold 505 is arranged on one side of the fixed mold 504, a cylinder 506 is installed on one side of the movable mold 505, one end of the cylinder 506 is connected to the outer shell 2, a connecting plate 507 is fixedly connected to one side of the fixed plate 503, racks 508 are slidably connected to the inner walls of both sides of the connecting plate 507, a gear 509 is arranged on one side of the rack 508, the teeth of the gear 509 and the rack 508 are meshed, a locking motor 510 is installed on one side of the connecting plate 507, the output end of the locking motor 510 is connected to the gear 509, and one end of the rack 508 is fixedly connected to a clamping plate 511.

[0026] It should be noted that during use, when the template needs to be replaced, the slider 502 and the fixed plate 503 are first driven to move through the linear slide rail 501, and the fixed mold 504 is driven to move at the same time. In this process, the locking motor 510 drives the gear 509 through the connecting plate 507 to drive the rack 508 to move, so that the clamping plate 511 is away from the template. At the same time, the cylinder 506 drives the movable mold 505 to separate the templates. When the template needs to be replaced, the replacement can be completed quickly, reducing the mold replacement time, minimizing the downtime, and improving production efficiency.

[0027] During use, plastic particles first enter the loading box 301 through the feed funnel 304. In this process, plastic particles with smaller particle sizes are discharged through the filter cartridge 303 and the waste pipe 306, and the remaining part enters the hot melt blow molding machine 4 through the discharge pipe 305. When the template needs to be replaced, the locking motor 510 drives the gear 509 through the connecting plate 507 to drive the rack 508 to move, so that the clamping plate 511 is away from the template. When the template needs to be replaced, the replacement can be completed quickly, reducing the mold replacement time, minimizing the downtime, and improving production efficiency.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
