Description

Technical Field

[0001] This utility model relates to the field of vacuum forming machines, and in particular to an automatic vacuum forming machine. Background Technology

[0002] An automatic thermoforming machine is a piece of equipment used to produce thermoformed packaging or plastic products. It features automatic feeding, forming, cooling, and unloading functions. It softens plastic sheets with hot air or a hot plate, and then uses a mold to thermoform them. It is suitable for producing blister packs, blister shells, and the like.

[0003] A search revealed Chinese Patent Publication No. CN220163208U, which discloses a high-efficiency fully automatic vacuum forming machine. The machine includes a base with top plates fixedly connected to the four corners of its upper surface. Two support frames on the same longitudinal plane have screw drive assemblies installed at the midpoint of their inner sidewalls. Each screw drive assembly includes a screw mounting bracket. A screw motor is bolted to the midpoint of the rear sidewall of the mounting bracket. The movable end of the screw motor passes through the rear sidewall of the mounting bracket and is connected to a transmission screw via a flexible coupling. A rotating bearing is installed on the inner side of the front sidewall of the mounting bracket, and the other end of the transmission screw is connected to the other end of the rotating bearing. This invention utilizes a material placement box to hold materials, and the screw drive assemblies drive an automatic feeding assembly that automatically fills the material, thus achieving automatic material filling and placement, significantly improving the working efficiency of the vacuum forming machine.

[0004] The aforementioned device, while achieving automatic material filling and placement through the setting of a sheet placement box and an automatic feeding machine, is quite large, which greatly increases the size of the vacuum forming machine. Furthermore, the sheets used in vacuum forming machines are generally thin, and the edges of the material need to be fixed during the vacuum forming process. The aforementioned feeding method not only makes it difficult to ensure the neatness and stability of the material during feeding, but also makes it inconvenient to limit the position of the sheet, making it impractical. Therefore, an automatic vacuum forming machine is proposed to solve the above problems. Utility Model Content

It is driven by a gas- and power-supplying device, which is existing technology and will not be described in detail here. The heating device 13 is fixedly connected to the lower part of the cylinder 14 and is used to heat the sheet material to facilitate vacuum forming. The middle part of the base 11...

This motor is used to facilitate the drive assembly. The second motor 160 is fixedly connected to the auxiliary frame 165.

[0035] Working Principle: During operation, the sheet material to be used in vacuum forming is conveyed from conveyor 2 to vacuum forming machine 1. As conveyor 2 conveys the material towards vacuum forming machine 1, positioning rod 22 positions the conveyed material to prevent it from shifting. Simultaneously, based on the thickness of the conveyed sheet material, telescopic rod 32 is activated, allowing it to adjust the height of mounting frame 34 via connecting rod 33, so that auxiliary roller 35 inside mounting frame 34 can contact the sheet material. Then, motor 36 is activated, driving auxiliary roller 35 to assist in conveying the sheet material towards the vacuum forming machine. The upper part of the base 11 of the machine allows the sheet material to be fed between the two positioning feeding components 16. At the same time, the electric lever 162 is activated, which, through the push rod 163, adjusts the limiting rod 164 and the components connected to the limiting rod 164 downward, so that the lower part of the roller 166 installed in the mounting groove 1641 can contact the sheet material. Then, the second motor 160 is activated, which drives the rotating shaft 167 connected to it to rotate. When the rotating shaft 167 rotates, the pulley 168 fixed to the rotating shaft 167 will also rotate. At this time, the belt 169 sleeved on the outside of the pulley 168 will be driven to generate transmission, thereby causing the pulley 168 on the other side to rotate. The shaft 167 fixed to the pulley 168 on the other side will also be driven. When the shaft 167 rotates, the roller 166 fixed to the shaft 167 will roll, thereby assisting the material in contact with it to be conveyed backward. When the material is completely placed on the upper part of the machine base 11, the second motor 160, the conveyor 2, and the first motor 36 can be stopped. The push rod 163 is driven by the electric rod 162 to make the roller 169 rotate backward. 66. Press the sheet material tightly, and then control the heating device 13 to move down through the cylinder 14 to heat the sheet material on the machine base 11. After the sheet material is heated, the template 15 can be pushed up through the device inside the machine base 11 to cooperate with vacuum forming, thereby facilitating product production. After the product is formed, control the template 15 to move down to demold the template 15 from the product. Then, turn on the second motor 160 to drive the roller 166 to rotate, thereby sending the vacuum-formed product to the rear of the vacuum forming machine 1 to complete the unloading.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
