DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1 to 10As shown, an automatic feeding device for a vacuum plastic packaging production line is finely designed and fully functional, and is mainly composed of the following parts: First, the basis of the device is a solid feeding track 1, on which a flexible feeding car 2 is installed. The feeding car 2 can move freely on the track 1 and is responsible for transporting the material from the storage area to the starting point of the production line. On one side of the feeding track 1, several groups of crawlers 11 are carefully arranged. The function of these crawlers 11 is to receive the material unloaded by the feeding car 2 and transport it to the next processing link. The key is that the end of the crawler 11 is equipped with a high-precision weighing component 3, which can monitor the weight of the material in real time, so as to judge the remaining amount of the material on the production line. Just above the weighing component 3, a vibration component 4 is installed, in which several groups of spring rods 41 are symmetrically arranged, and the top of each spring rod 41 is connected to a vibration plate 42. Driven by the spring rod 41, the vibration plate 42 can effectively shake the piled materials, prevent the accumulation of materials, and ensure that the materials can flow evenly to the next link. Behind the weighing assembly 3 and the vibration assembly 4 is a carefully designed lifting assembly 5, which can accurately lift the individual materials that have been vibrated to prepare for the packaging of the materials. Finally, behind the lifting assembly 5 is a packaging assembly 6, which includes a plastic bag conveyor belt, a paddle bracket is installed above the conveyor belt, and a paddle is rotatably arranged on the bracket. The function of these paddles is to smoothly pry the materials lifted by the lifting assembly 5 into the plastic bag conveyor belt, and the materials are then fed into the plastic sealing equipment by the conveyor belt to complete the entire process of automatic feeding. This design not only improves production efficiency, but also ensures the accuracy of material feeding and the consistency of packaging.

[0027] like Figure 3 As shown, the feeder 2 in the automatic feeding device for the vacuum plastic packaging production line is a key component, and its structural design is as follows: the feeder 2 includes a solid chassis 21, on which an axle seat 22 is installed, and a bucket 23 is rotatably arranged on the axle seat 22, and the bucket 23 is used to carry materials and move on the feeding track 1. A trap door 24 is arranged on one side of the bucket 23, and the function of the trap door 24 is to open at an appropriate position so as to unload the materials from the bucket 23 to the crawler 11. In addition, the chassis 21 is also equipped with a signal receiver 25, which is used to receive the weighing data from the weighing component 3, so as to monitor the weight information of the material in real time. The data transmission of the signal receiver 25 is essential to ensure the accurate feeding of the material. At the same time, a controller 26 is also arranged on the chassis 21, and the controller 26 is connected to the signal receiver 25, which is responsible for controlling the movement of the feeder 2 on the feeding track 1 according to the received weighing data and the preset program. This design enables the feeding vehicle 2 to automatically adjust its speed and position according to the needs of the production line, thereby achieving efficient and accurate material transportation.

[0028] like Figure 1As shown, guard plates 12 are provided on both sides of the crawler track 11 to effectively prevent material from overflowing.

[0029] like Figure 4 and Figure 7 As shown, the weighing assembly 3 in the automatic feeding device for the vacuum plastic packaging production line is a key part for measuring the weight of the material, and its detailed structure is as follows: the base 31 is the basic part of the weighing assembly 3, which provides a stable supporting platform for the weighing platform 32 and other related components. The weighing platform 32 is installed on the base 31. It is a platform for placing and weighing materials. It needs to be strong enough to bear the weight of the material and is usually designed to be flat to ensure accurate weighing; the telescopic rod 33 is set on the weighing platform 32, and its function is to adjust the height of the weighing platform 32 to adapt to materials of different sizes, or to assist in the placement of materials. and removal; the mass sensor 34 is installed on the base 31 and is connected to the weighing platform 32. It is used to detect the weight of the material placed on the weighing platform 32, and can convert the weight data of the material into an electrical signal and send it to the signal receiver 25 for further processing and control. The design of the entire weighing assembly 3 ensures that the material can be accurately weighed before entering the next process, which is very important for ensuring product quality and the degree of automation of the production line. The weighing data sent by the mass sensor 34 can be received and processed by the controller 26, thereby realizing precise control of the feeding vehicle 2 and ensuring that the material is transported according to the set weight requirements.

[0030] like Figure 2 and Figure 6 As shown, the vibration assembly 4 is a well-designed mechanical device, whose main function is to process and convey materials through vibration. The core of the assembly is a vibration chassis 43 mounted on a telescopic rod 33. The design of this chassis allows it to provide support during operation. Above the vibration chassis 43, spring rods 41 are fixed. These spring rods 41 not only play a supporting role, but also provide elastic restoring force during the vibration process, making the vibration more uniform and effective. The top of the spring rod 41 is connected to the vibration plate 42, which is a key component that is directly responsible for generating vibration to process materials. The design of the vibration plate 42 enables it to throw and disperse the material when vibrating, thereby achieving screening, grading or uniform distribution of the material. On top of the vibration plate 42, a material tray 44 is placed, which is a container for loading materials. Its shape and size are designed according to actual needs to adapt to different material types and processing volumes. The entire vibration assembly 4 is designed to be inclined, and its inclination angle ensures that the material can slide smoothly along the surface of the material tray 44 to the next assembly under the action of gravity. Specifically, the angle between the material tray 44 and the track is 30 degrees, which ensures the smooth flow of materials and avoids rolling or jumping of materials due to excessively large angles, thereby improving the stability and efficiency of material transportation.

[0031] like Figure 5 As shown, the lifting assembly 5 is based on a hydraulic cylinder base 51, a hydraulic cylinder 52 is firmly mounted on the hydraulic cylinder base 51, and an internal push rod 53 can move up and down by hydraulic action. The top of the push rod 53 is connected to a deflection plate 54, which is a key component and can be deflected laterally under the action of a rotating seat 56 set on the push rod 53. Above the hydraulic cylinder base 51, a cover 55 covers the entire structure, providing protection while also playing a sealing role. A guide baffle 57 is installed on the inner side of the cover 55, located behind the deflection plate 54, and its function is to guide the flow of materials. There are multiple grille holes 57 evenly distributed on the deflection plate 54, each of which corresponds to a grille 58 on the top of the push rod 53. When the hydraulic cylinder 52 is working, the push rod 53 is pushed upward, pushing the deflection plate 54 to deflect to both sides, and at this time, the grille 58 extends from the grille hole 57 to separate the materials, so that a part of the materials can remain on the deflection plate 54. During the deflection process, excess material will fall from both sides of the deflection disc 54. Guided by the guide baffle 57, the material accurately falls into the next set of deflection discs 54, and only one material is finally retained on each deflection disc 54, thereby achieving accurate separation and positioning of the material.

[0032] like Fig. 9 and Fig.10 As shown, the packaging component 6 includes a plastic bag conveyor belt 61, a paddle bracket 62 is arranged above the plastic bag conveyor belt 61, and a paddle 63 is rotatably arranged on the paddle bracket 62. When the material is separated and positioned in the lifting component 5, the paddle 63 pries the material into the plastic bag and sends it to the next link for plastic sealing.

[0033] Working process:

[0034] On the vacuum packaging production line, the working process of the automatic feeding device is as follows: first, the operator loads the material into the bucket 23 of the feeding vehicle 2, the feeding vehicle 2 moves to the starting point of the production line on the feeding track 1, and after the signal receiver 25 receives the weighing data of the weighing component 3, the material is accurately unloaded onto the crawler 11 according to the instruction of the controller 26. The guard plates 12 on both sides of the crawler 11 effectively prevent the material from overflowing, and transport the material to the weighing platform 32 for weight monitoring; the weighed material is adjusted to a suitable height through the telescopic rod 33, and then enters the vibration component 4, the vibration chassis 43 supports the spring rod 41 and the vibration plate 42, and the vibration generated by the vibration plate 42 The material is shaken and evenly distributed on the material receiving tray 44, and the material slides toward the lifting assembly 5 along an inclined angle of 30 degrees; the hydraulic cylinder 52 in the lifting assembly 5 pushes the push rod 53 to make the deflection plate 54 deflect laterally, and the material is accurately separated and positioned through the cooperation of the grille hole 57 and the grille 58, and the excess material falls from both sides of the deflection plate 54 to the next set of deflection plates 54; the separated material is finally dialed from the dial bracket 62 by the paddle 63 into the plastic bag conveyor belt 61, and the plastic bag moves with the conveyor belt to the sealing equipment, completes automatic loading and prepares for plastic sealing, and the whole process is highly automated, ensuring the accuracy of material loading and the consistency of packaging, greatly improving production efficiency.
