[0002] Plastic blow molding equipment is usually called a blow molding machine. This machine heats the plastic and blows it into shape to make various plastic products. Blow molding machines are usually equipped with a feeding mechanism to transport plastic particles into the blow molding machine. However, the feeding mechanism is equipped with a silo at a certain height from the ground, and workers are required to pour the plastic particles into the silo. At the same time, each bag containing plastic particles needs to be opened in advance, and opening each bag will increase the time cost of the production process. Bags containing plastic particles are usually heavy, and workers need to lift the bags to the corresponding height before pouring the plastic particles into the silo. In the process of carrying the bags, if the workers do not stand properly or use appropriate handling tools, they will fall or sprain due to unstable center of gravity. Utility Model Content

[0003] The utility model aims to propose a plastic blow molding device to solve the problem that manual high-position loading and transportation are required in the background technology, resulting in complicated procedures and low safety.

[0005] Optionally, the supporting mechanism includes a pair of enclosures connected to the top of the feed bin, the top of the enclosure is fixedly connected to the support plate, the lower surface of the support plate is fixedly connected to a plurality of linearly arranged hooks, and the ends of the hooks away from the support plate are provided with bag-piercing tips for piercing into plastic particle bags.

[0006] Optionally, the bag opening assembly includes a support box fixedly connected to the enclosure plate, a multi-stage cylinder is provided inside the support box, a circular slider fixedly connected to the piston rod of the multi-stage cylinder is slidably connected inside the support box, a slide groove is provided on the support box, a sliding blade is slidably connected inside the slide groove, and one end of the sliding blade inside the support box is fixedly connected to the circular slider.

[0007] Optionally, the conveying mechanism includes a conveyor belt arranged therein, the conveying mechanism is connected to the top of the feed bin, and a pair of supporting legs for supporting the conveying mechanism are provided at the bottom end of the conveyor belt.

[0008] Optionally, a feeding bracket for supporting the operation of the feeding mechanism is provided at the bottom of the feeding mechanism.

[0009] Optionally, a material guide bin is installed on the blow molding machine body and is located just below the top of the feeding mechanism and is used to receive the material transported by the feeding mechanism.

[0010] Optionally, the plastic particle bags on the supporting mechanism are all hung on the hooks through a conveying mechanism.

[0011] Compared with the prior art, the utility model has the following beneficial technical effects:

[0012] The utility model utilizes the coordination of structures such as a feeding mechanism, a feeding bin, a conveying mechanism, a supporting mechanism and a bag opening assembly. The conveying mechanism can automatically convey plastic particles from a low place to the feeding bin, and workers do not need to lift heavy objects manually, thereby not only reducing the labor intensity of workers, but also reducing the risk of work-related injuries to workers.

[0024] Example

[0025] like Figure 1-3 As shown, a plastic blow molding device proposed by the utility model includes a blow molding machine body 1, a feeding mechanism 3 and a feeding bin 4 arranged on the feeding mechanism 3, a feeding bracket 2 for supporting the operation of the feeding mechanism 3 is provided at the bottom of the feeding mechanism 3, a guide bin 11 for receiving the material conveyed by the feeding mechanism 3 is installed on the blow molding machine body 1 and is located just below the top of the feeding mechanism 3, and also includes: a conveying mechanism 6, which is installed on the feeding bin 4 and is used to convey bags containing plastic particles into the feeding bin 4; a supporting mechanism arranged on the feeding bin 4 and is used to hang plastic particle bags transported to the feeding bin 4 and about to fall into the feeding bin 4, and the plastic particle bags on the supporting mechanism are all hung on the hook 51 through the conveying mechanism 6; a bag opening component, which is used to quickly open the plastic particle bags hung on the supporting mechanism.

[0026] Furthermore, the supporting mechanism includes a pair of panels 5 connected to the top of the feed bin 4. The panels 5 can guide the flow of materials, ensure that the materials are transported along a predetermined path and direction, and improve production efficiency and accuracy. A support plate 53 is fixedly connected to the top of the panel 5, and a plurality of hooks 51 arranged linearly are fixedly connected to the lower surface of the support plate 53. The ends of the hooks 51 away from the support plate 53 are provided with bag-tying tips 52 for piercing into the plastic particle bags. The design of the bag-tying tips 52 enables the hooks 51 to easily penetrate the material of the bag without the need for additional force or tools. This simplifies the operating steps and improves operating efficiency. At the same time, the hooks 51 with the bag-tying tips 52 can complete the hanging or fixing of the bag more quickly, saving the operator's time and speeding up the production process.

[0027] Among them, the bag opening assembly includes a support box 7 fixedly connected to the enclosure 5, and a multi-stage cylinder 71 is arranged inside the support box 7. The function of the multi-stage cylinder 71 refers to a pneumatic device with multiple working levels or multiple cylinder stages. They are usually composed of a main cylinder and one or more auxiliary cylinders, which can be started or stopped in sequence as needed to achieve more complex motion control or mechanical operations. A circular slider 72 fixedly connected to the piston rod of the multi-stage cylinder 71 is slidably connected inside the support box 7, and a slide groove 74 is provided on the support box 7. A sliding blade 73 is slidably connected inside the slide groove 74. The sliding blade 73 is a common tool, which is usually used for cutting, severing or cutting materials. The sliding blade 73 is fixedly connected to the circular slider 72 at one end inside the support box 7.

[0028] Furthermore, the conveying mechanism 6 includes a conveyor belt 61 disposed therein, and the function of the conveyor belt 61 is to enable the worker to convey the plastic particle bag to a designated high place by simply placing the plastic particle bag at a low place of the conveying mechanism 6. The conveying mechanism 6 is connected to the top of the feeding bin 4, and a pair of supporting legs 62 for supporting the conveying mechanism 6 are disposed at the bottom end of the conveyor belt 61.

[0029] In this embodiment, when the plastic blow molding equipment is needed, the plastic particle bag is directly placed on the conveyor belt 61 at the bottom of the conveying mechanism 6, and the plastic particle bag is conveyed to the highest point of the conveying mechanism 6 by the started conveyor belt 61. At this time, the plastic particle bag will fall into the inside of the feeding bin 4 due to the action of gravity, but when falling down, the bag tying tips 52 set on the multiple hooks 51 on the lower surface of the support plate 53 will hook the plastic particle bag and make the plastic particle bag suspended directly above the feeding bin 4. At this time, it is only necessary to start the multi-stage cylinder 71 in the support box 7, and the piston rod of the multi-stage cylinder 71 drives the circumferential slider 72 to slide in the support box 7, and the circumferential slider 72 drives the sliding blade 73 to slide along the slide groove 74, so that the sliding blade 73 cuts the plastic particle bag suspended above the feeding bin 4. Then the plastic particles in the plastic particle bag slide into the feeding bin 4 due to the action of gravity, and finally the workers remove the scratched plastic particle bag from the supporting mechanism, and then shake the plastic particle bag to completely shake the plastic particles in the plastic particle bag into the inside of the feeding bin 4, and then the empty plastic particle bag can be placed in one place for unified treatment.
