Description

Technical Field

[0001] The utility model relates to the field of plastic particle packaging and processing, in particular to a supporting mechanism for a plastic particle packaging machine. Background Art

[0002] Plastic particles refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic particles include general-purpose plastics, engineering plastics, and special plastics. Among them, general-purpose plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc.; engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbonate silicone, etc.; special plastics: thermosetting plastics, functional polymer plastics, such as artificial kidneys. With the development of society, the use of plastic particles is becoming more and more extensive.

[0003] In order to facilitate the transportation and processing of plastic particles, the produced plastic particles are generally packaged in packaging bags, and then the bags of packaged plastic particles are transported to the factory for further processing as needed. However, the existing packaging machines (equipment) used for packaging plastic particles generally place the packaging bags directly on the processing operation table during the packaging process, and then fill and package them through the packaging machine, and finally "seal" the packaging bags. In the process of filling the packaging bags with plastic particles, as the number of plastic particles in the packaging bags increases, the overall weight of the packaging bags increases. Since the existing "placing table" for placing plastic particle packaging bags has no limiting structure, it may cause the packaging bags to "shift", and the "sealing mechanism" of the plastic particle packaging machine cannot seal the packaging bags, and the plastic particles cannot be poured into the packaging bags, resulting in a waste of raw materials.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1 to 3 As shown, a support mechanism for a plastic granule packaging machine is used to support and limit the packaging bag filled with plastic granules through the plastic granule packaging machine. The support mechanism includes a support base 1, which is installed and connected to a connecting bracket 2 used to connect to the packaging machine frame; the support base 1 is provided with a limiting blind groove for limiting the packaging bag filled with plastic granules, and a supporting bottom plate 11 for supporting the packaging bag filled with plastic granules is arranged in the limiting blind groove, and the supporting bottom plate 11 is elastically arranged with the bottom end of the limiting blind groove provided by the support base 1; a limiting jaw 12 is movably provided above the limiting blind groove provided by the support base 1, which can be relatively movable and is used to clamp and limit the packaging bag filled with plastic granules placed in the limiting blind groove, and the two limiting jaws 12 are connected to the support base 1 through a limiting structure. By conveying and moving the packaging bag to the limiting blind groove of the support base 1 and placing the packaging bag on the support bottom plate 11 in the limiting blind groove, even as the number of plastic particles in the packaging bag increases and the weight increases, the limiting blind groove can limit the packaging bag containing the plastic particles; and as the number of plastic particles in the packaging bag increases and the weight increases, the two limiting jaws 12 move to clamp and limit the packaging bag containing the plastic particles placed in the two limiting jaws 12, thereby preventing the packaging bag containing the plastic particles from moving and the top sealing port from being misplaced, which would affect the sealing of the packaging bag by the packaging machine.

[0025] Further, in the embodiment, the limiting structure provided includes a first limiting link 13, a second limiting link 14, a horizontal transverse rod 15 and a sliding guide seat 16, the middle part of the first limiting link 13 is rotatably connected to the support base 1, a first slider is slidably provided in one end of the first limiting link 13, the first slider is rotatably connected to the support base plate 11 through a hinge seat, a second slider is slidably provided in the other end of the first limiting link 13, the second slider is rotatably connected to one end of the second limiting link 14, the middle part of the second limiting link 14 is rotatably connected to the support base 1, a third slider is slidably provided in the other end of the second limiting link 14, the third slider is rotatably connected to one end of the horizontal transverse rod 15, the sliding guide seat 15 is fixedly connected to the support base 1, the horizontal transverse rod 15 is slidably provided in the sliding guide seat 16, the other end of the horizontal transverse rod 15 is connected to the limiting clamp 12, and the bottom end of the sliding guide seat 16 is connected to the support base 1. In addition, the bottom end of the support base plate 11 is connected to a limiting shaft 111, and the other end of the limiting shaft 111 is movably inserted into the bottom end surface of the limiting blind groove provided in the support base 1. A protection spring 112 is inserted into the limiting shaft 111, and one end of the protection spring 112 is connected to the bottom end surface of the supporting base plate 11, and the other end of the protection spring 112 is connected to the bottom end surface of the limiting blind groove provided in the support base 1. As the amount of plastic particles poured into the packaging bag by the plastic packaging machine increases, the overall weight of the packaging bag increases. While the limiting blind groove provided in the support base 1 limits the packaging bag containing the plastic particles, the packaging bag and the plastic particles in the packaging bag transmit force to the support base plate 11 at the bottom end of the packaging bag through the action of gravity. The support base plate 11 is subjected to gravity, driving the limiting shaft 111 to move downward, and at the same time, compressing the protection spring 112 inserted into the limiting shaft 111, playing the role of "elastic protection". Furthermore, as the support base plate 11 moves downward, the support base plate 11 drives the first limit links 13 connected on both sides to move, so that the two first limit links 13 respectively drive the two horizontal transverse rods 15 to move and move relatively from the sliding guide seat 16 through the second limit links 14, and perform "active clamping and limiting" on the packaging bag containing plastic particles placed between the two limit jaws 12, so as to avoid the packaging bag from shifting as the number of plastic particles increases, thereby avoiding affecting the sealing of the packaging bag by the packaging machine.

[0026] Furthermore, in the embodiment, in order to ensure stable positioning of the packaging bag containing plastic particles, a movable limiting structure for clamping and limiting the packaging bag containing plastic particles is movably arranged above the two limiting jaws 12; the movable limiting structure comprises a first limiting clamp 21 and a second limiting clamp 31, and the first limiting clamp 21 and the second limiting clamp 31 are movably arranged above the two limiting jaws 12; the first limiting clamp 21 is movably connected to one side end of the connecting bracket 2 through the first limiting bracket 22; the second limiting clamp 31 is movably connected to the other side end of the connecting bracket 2 through the second limiting bracket 32. Moreover, the bottom end of the first position-limiting bracket 22 is rotatably connected to one side end of the support base 1 through a rotating shaft; the bottom end of the first position-limiting bracket 22 is also connected to a first connecting rod, a first curved rod 23 is hinged on the first connecting rod, the other end of the first curved rod 23 is hinged to the output end of the first movable cylinder 24 through a hinge seat, and the first movable cylinder 24 is fixed to the connecting bracket 2 through bolts. Similarly, the second position-limiting bracket 32 ​​has a similar connection structure to the first position-limiting bracket 22, that is, the bottom end of the second position-limiting bracket 32 ​​is rotatably connected to one side end of the connecting bracket 2 through a rotating shaft; the bottom end of the second position-limiting bracket 32 ​​is also connected to a second connecting rod, a second curved rod 33 is hinged on the second connecting rod, the other end of the second curved rod 33 is hinged to the output end of the second movable cylinder 34 through a hinge seat, and the second movable cylinder 34 is fixed to the connecting bracket 2 through bolts. With this design, the first movable cylinder 24 is moved, and the first movable cylinder 24 drives the first limiting bracket 22 to move through the first curved rod 23, thereby driving the first limiting clamp 21 to move through the first limiting bracket 22; similarly, the second movable cylinder 34 is moved, and the second movable cylinder 34 drives the second limiting bracket 32 ​​to move through the second curved rod 33, thereby driving the second limiting clamp 31 to move through the second limiting bracket 32; furthermore, the first limiting clamp 21 can be driven by the first movable cylinder 24 and the second limiting clamp 31 can be driven by the second movable cylinder 34, and the two limiting clamps can move relatively and close to each other, so as to support and limit the "upper part" of the packaging bag containing plastic particles placed between the first limiting clamp 21 and the second limiting clamp 31, so as to avoid displacement of the packaging bag as the plastic particles in the packaging bag increase, thereby affecting the sealing quality of the packaging bag by the packaging machine. From the perspective of the support mechanism structure of the entire design improvement, the support mechanism is used to support and limit the packaging bag filled with plastic particles that is being filled through the plastic particle packaging machine, to avoid the movement of the packaging bag as the amount of plastic particles increases, thereby affecting the sealing of the packaging machine, and to avoid the failure of plastic particles to be filled into the packaging bag due to the movement of the packaging bag, resulting in spillage and waste of raw materials.
