Description

Technical Field

[0001] This utility model specifically relates to the field of vacuum forming machine technology, and more specifically to a high-efficiency vacuum forming machine capable of automatically processing harmful gases. Background Technology

[0002] A vacuum forming machine is a device that uses heating and vacuum adsorption processes to process plastic sheets into products of specific shapes. It is widely used in packaging, daily necessities, electronics, medical and other industries. The heating device of the vacuum forming machine softens the sheet through a ceramic heating plate. The softened sheet is then quickly moved by a mechanical device to the top of the mold station. Air is drawn out through evenly distributed air holes on the surface of the mold, creating a negative pressure environment below the mold. Atmospheric pressure pushes the softened sheet downward to fit the mold, filling the concave and convex contours of the mold to form the desired shape. Finally, it is cooled and solidified.

[0003] However, in practice, it has been noted that the core process of a vacuum forming machine involves heating plastic sheets to a softened state and then forming them using a mold. During use, the chemical properties of the sheets can produce some harmful gases when exposed to high temperatures. For example, commonly used polyvinyl chloride (PVC) materials easily decompose at high temperatures to produce hydrogen chloride gas. PET, PS, and PP materials may also produce volatile organic compounds such as benzene, toluene, and xylene at high temperatures, which are toxic and irritating. This can cause physical harm to workers, resulting in poor safety during use. Utility Model Content

This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-8 This utility model provides a high-efficiency vacuum forming machine capable of self-treating harmful gases, including a vacuum forming machine body 1, and an exhaust gas treatment mechanism for treating harmful gases is provided at the rear of the vacuum forming machine body 1, and the exhaust gas treatment mechanism is fixedly connected to the vacuum forming machine body 1.

[0033] The exhaust gas treatment mechanism includes a mounting bracket 7 fixedly connected to the main body 1 of the vacuum forming machine. A ring-shaped fixing clip 10 is fixedly connected to the side of the mounting bracket 7 away from the main body 1 of the vacuum forming machine. A chemical treatment tank 8 and an activated carbon adsorption tank 9 are fixedly connected to both sides of the ring-shaped fixing clip 10, respectively.

[0034] The chemical treatment tank 8 includes a corrosion-resistant sealed tank 81 bolted to an annular fixing clamp 10. A fixed connecting pipe 85 is fixedly connected to the bottom of the corrosion-resistant sealed tank 81, and a rotating spray pipe 86 located inside the corrosion-resistant sealed tank 81 is movably connected above the fixed connecting pipe 85.

[0035] Furthermore, the anti-corrosion sealed tank 81 is integrally provided with an air inlet pipe 82 at the top, and an exhaust gas inlet pipe 6 that communicates with the inside of the blister machine body 1 is fixedly connected to the air inlet pipe 82. Moreover, the bottom of the anti-corrosion sealed tank 81 is integrally provided with an outlet pipe 84 for the recovery and treatment liquid.

[0036] More specifically, the liquid outlet pipe 84 is integrally provided with a connecting pipe 83 that communicates with the activated carbon adsorption tank 9 on the side near the activated carbon adsorption tank 9, and an exhaust pipe 91 is integrally provided above the activated carbon adsorption tank 9.

[0037] Furthermore, an alkaline treatment liquid storage tank 5 is provided below the chemical treatment tank 8 and is fixedly connected to the mounting bracket 7, and the bottom of the liquid outlet pipe 84 extends through the alkaline treatment liquid storage tank 5 to the inside of the alkaline treatment liquid storage tank 5.

[0038] By adopting the above technical solution, the waste gas enters the anti-corrosion sealed tank 81 through the air inlet pipe 82. After being sprayed with a treatment liquid containing an alkaline solution inside the anti-corrosion sealed tank 81, the chlorine-containing waste gas is treated. The treated gas then enters the activated carbon adsorption tank 9 through the connecting pipe 83. After being adsorbed by the activated carbon inside the activated carbon adsorption tank 9, organic matter such as styrene, methyl methacrylate, and formaldehyde in the waste gas is adsorbed, thereby ensuring the treatment effect of the waste gas and improving the safety of the vacuum forming machine during use.

[0039] Furthermore, the fixed connection pipe 85 includes a pipe joint 851 that penetrates the bottom of the anti-corrosion sealing tank 81, and the outer side of the anti-corrosion sealing tank 81 is integrally provided with a flange 852 that is fixedly connected to the anti-corrosion sealing tank 81, and the top of the pipe joint 851 extends to the inner side of the anti-corrosion sealing tank 81.

[0040] Furthermore, the rotating spray pipe 86 includes a hollow column 861, and the top of the pipe joint 851 is inserted into the bottom of the inner side of the hollow column 861, and the outer side of the hollow column 861 is provided with eccentric spray holes 862 in a ring array.

[0041] More specifically, the hollow column 861 is fixedly connected to an isolation plate frame 863 corresponding to the eccentric spray hole 862, and the top of the hollow column 861 is interference-fitted with a bearing, and the outer ring of the bearing is interference-fitted with the top of the anti-corrosion sealing tank 81.

[0042] By adopting the above technical solution, the alkaline treatment solution in the alkaline treatment solution storage tank 5 is sent into the hollow column 861. The alkaline treatment solution is evenly sent into the hollow column 861 after being divided by the isolation plate frame 863. The eccentric spray hole 862 set on the hollow column 861 can not only spray the treatment solution into the anti-corrosion sealed tank 81, but also apply a lateral thrust to the hollow column 861, so that the hollow column 861 can rotate inside the anti-corrosion sealed tank 81, thereby improving the treatment effect of the waste gas.

[0043] Furthermore, the top of the pipe joint 851 is inserted into the bottom of the hollow column 861, and a sealing ring 853 is provided at the connection between the pipe joint 851 and the hollow column 861, and the sealing ring 853 is interference-fitted with the pipe joint 851.

[0044] By adopting the above technical solution, the top of the pipe joint 851 is inserted into the bottom of the hollow column 861, and a sealing ring 853 that is interference-fitted with the pipe joint 851 is also provided at the connection, thereby ensuring the sealing of the connection between the pipe joint 851 and the hollow column 861. At the same time, it can also ensure that the hollow column 861 rotates normally on the pipe joint 851, thereby ensuring the rotation of the hollow column 861 during the spraying process.

[0045] Furthermore, a protective shell 4 is fixedly connected to the top of the alkaline treatment liquid storage tank 5, and the exhaust pipe 91 and the exhaust gas inlet pipe 6 extend through the protective shell 4 to the top of the protective shell 4.

[0046] Furthermore, the main body 1 of the vacuum forming machine is mainly composed of a vacuum forming machine turntable 2 for transporting materials and core components such as a heating system, a forming mechanism, a cooling system, a transmission system, and a control system. The forming mechanism includes a forming mold and an air pump that draws negative pressure from the mold. The heated sheet covers the surface of the mold, and the air pump draws out the gas through the holes in the mold (the above-mentioned vacuum forming machine adopts a conventional technical solution in the field, and its working principle is well known to those skilled in the art, so it will not be described in detail).

[0047] The extracted gas is guided to the corrosion-resistant sealed tank 81 for treatment through the exhaust gas inlet pipe 6 connected to the exhaust port.

[0048] Furthermore, the treated liquid after spraying collects at the bottom of the anti-corrosion sealed tank 81 and returns to the alkaline treated liquid storage tank 5 through the liquid outlet pipe 84 at the bottom of the anti-corrosion sealed tank 81, thus realizing the circulation of the treated liquid.

[0049] Furthermore, a water supply pump 11 is fixedly connected above the alkaline treatment liquid storage tank 5. The inlet of the water supply pump 11 extends through a pipe to the bottom of the inner side of the alkaline treatment liquid storage tank 5, while the other end of the water supply pump 11 is connected to the bottom of the pipe joint 851 through a fixedly connected inlet pipe 12.

[0050] The working principle of this utility model is as follows: During use, the sheet material is first placed on the vacuum forming machine turntable 2 for processing. The waste gas generated during processing enters the anti-corrosion sealed tank 81 through the waste gas inlet pipe 6 and the air inlet pipe 82. Simultaneously, the liquid supply pump 11 delivers the alkaline solution from the alkaline treatment liquid storage tank 5 into the hollow column 861 through the liquid inlet pipe 12. After being divided by the isolation plate frame 863, the treatment liquid is evenly distributed into the hollow column 861. Furthermore, the hollow column 861 has eccentrically arranged spray holes 862 in a circular array. Due to the eccentric arrangement of the spray holes 862, the treatment liquid can be effectively sprayed through the eccentric spray holes 862. The liquid sprayed into the anti-corrosion sealed tank 81 also applies a lateral thrust to the hollow column 861, allowing the hollow column 861 to rotate inside the anti-corrosion sealed tank 81. The treatment liquid neutralizes the acidic and harmful gases in the waste gas. The neutralized waste gas then enters the activated carbon adsorption tank 9 through the connecting pipe 83. After adsorption by the activated carbon filter screen inside the activated carbon adsorption tank 9, organic matter such as styrene, methyl methacrylate, and formaldehyde in the waste gas is adsorbed. Finally, the treated waste gas is discharged through the exhaust pipe 91, thereby reducing the harm of the waste gas to the human body. The structure is simple, the operation is very convenient, and it effectively reduces the intensity of manual labor.

[0051] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0052] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
