Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of defoaming devices for PET film mixing, and in particular to a defoaming device for PET film mixing. Background Technology
[0002] PET film is a high-performance plastic film made from PET resin through processes such as extrusion, stretching, and coating. It has excellent mechanical strength, transparency, temperature resistance, and chemical stability, and is widely used in packaging, electronics, photovoltaics, printing, and other fields.
[0003] Existing PET film raw materials are dried and dehumidified using a defoamer before use to prevent the formation of bubbles due to moisture evaporation during screw extrusion. However, existing defoamers have an open top, allowing the evaporated moisture to diffuse to the outside. Since the PET film raw material is at a high temperature after drying, it comes into direct contact with the outside cold air, causing condensation on its outer surface and increasing the humidity of the PET film raw material. This is detrimental to PET film production. Therefore, we provide a defoaming device for PET film mixing. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing PET film raw material defoaming machines, which cannot guarantee that the material will not become damp after drying, and to provide a defoaming device for PET film mixing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a defoaming device for mixing PET film, comprising: a defoaming machine, a suction mechanism provided on the outside of the defoaming machine, the suction mechanism including a top cover, the top cover being placed on top of the defoaming machine, a rubber pad provided at the bottom of the top cover, two fixing tubes sleeved inside the defoaming machine, the fixing tubes being fixedly connected to the defoaming machine, a temperature and humidity detector sleeved inside the fixing tube, the temperature and humidity detector being fixedly connected to the fixing tube, a fixing ring sleeved inside the fixing tube, a motor sleeved inside the fixing ring, the motor being fixedly connected to the fixing ring, a fan blade fixedly connected to one end of the motor, a barrier ring sleeved inside the fixing tube, and a connecting mechanism provided on the outside of the top cover.
[0006] In a preferred embodiment, the rubber pad is placed in a sealing groove opened on the defoaming machine, the fixing ring is fixedly connected to the fixing tube, the barrier ring is fixedly connected to the fixing tube, and a cover is sleeved on the outer surface of one end of the fixing tube.
[0007] In a preferred embodiment, the cover is threadedly connected to the fixed pipe, a screw block is provided on the outer side of the cover, the screw block is fixedly connected to the cover, and a pull block is provided on the top of the top cover, the pull block is fixedly connected to the top cover.
[0008] In a preferred embodiment, the connecting mechanism includes a first fixing block, which is fixedly connected to the top cover, and a second fixing block is provided at the bottom of the first fixing block, which is fixedly connected to the defoamer.
[0009] In a preferred embodiment, the top of the second fixing block is provided with a threaded rod, which is fixedly connected to the second fixing block.
[0010] In a preferred embodiment, the fixing block is fitted onto the outer surface of the threaded rod, and the fixing block is slidably connected to the threaded rod.
[0011] In a preferred embodiment, a nut is fitted onto the outer surface of the threaded rod, and the nut is threadedly connected to the threaded rod.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, through the installation of a suction mechanism, allows the water vapor generated during drying inside the defoamer to be discharged outwards, thereby reducing the humidity of the PET film raw material inside the defoamer. This prevents the formation of bubbles due to adhering moisture during use. Simultaneously, a top cover and rubber gasket are installed, which work together to seal the top of the defoamer, preventing cold air from seeping into the defoamer from the top. This prevents the PET film raw material, which is at a relatively high temperature, from becoming damp upon contact with cold air. A temperature and humidity detector is also included to monitor the humidity of the air supplied from the fixed pipe, allowing for better determination of the PET film raw material's humidity and the appropriate timing for discharge. A connecting mechanism is also included, which works in conjunction with the suction mechanism to ensure the top cover remains tight and stable. Attached Figure Description

[0017] 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.
[0018] Example 1 like Figures 1-3 As shown, this utility model provides a technical solution: a defoaming device for mixing PET film, comprising: a defoamer 1, a suction mechanism 2 on the outside of the defoamer 1, the suction mechanism 2 including a top cover 21, the top cover 21 being placed on top of the defoamer 1, a rubber pad 22 at the bottom of the top cover 21, two fixing tubes 23 being sleeved inside the defoamer 1, the fixing tubes 23 being fixedly connected to the defoamer 1, a temperature and humidity detector 24 being sleeved inside the fixing tubes 23, the temperature and humidity detector 24 being fixedly connected to the fixing tubes 23, a fixing ring 25 being sleeved inside the fixing tubes 23, and a motor 26 being sleeved inside the fixing ring 25. The motor 26 is fixedly connected to the fixing ring 25. One end of the motor 26 is fixedly connected to the fan blade 27. The inside of the fixing tube 23 is fitted with a barrier ring 28. The outside of the top cover 21 is provided with a connecting mechanism 3. The rubber pad 22 is placed in the sealing groove opened on the defoamer 1. The fixing ring 25 is fixedly connected to the fixing tube 23. The barrier ring 28 is fixedly connected to the fixing tube 23. One end of the fixing tube 23 is fitted with a cover 29. The cover 29 is threadedly connected to the fixing tube 23. The outside of the cover 29 is provided with a screw block 201. The screw block 201 is fixedly connected to the cover 29. The top of the top cover 21 is provided with a pull block 202. The pull block 202 is fixedly connected to the top cover 21.
[0019] In this embodiment, a top cover 21 and a rubber pad 22 are provided, with the rubber pad 22 placed inside the sealing groove on the defoamer 1. The rubber pad 22 is installed at a height slightly higher than the top of the defoamer 1, allowing the top cover 21 to compress the rubber pad 22 and fill the gap between the top cover 21 and the defoamer 1, thus achieving a seal and preventing cold air from entering the defoamer 1. A motor 26 and a fan blade 27 are also provided, with the motor 26 driving the fan blade 27 to rotate at high speed. The fan blade 27 then drives the airflow within the fixed tube 23, causing the air inside the fixed tube 23 to be discharged outwards. This creates a negative pressure inside the fixed tube 23, allowing the hot air inside the defoamer 1 to be discharged outwards through the fixed tube 23. This also allows the moisture generated during the drying of the PET film raw material to escape from the defoamer 1. Furthermore, a baffle ring 28 is provided to prevent the PET film raw material inside the defoamer 1 from being discharged outwards by the suction mechanism 2.
[0020] Example 2 like Figures 1-3 As shown, the connecting mechanism 3 includes a first fixing block 31, which is fixedly connected to the top cover 21. The bottom of the first fixing block 31 is provided with a second fixing block 32, which is fixedly connected to the defoamer 1. The top of the second fixing block 32 is provided with a threaded rod 33, which is fixedly connected to the second fixing block 32. The first fixing block 31 is sleeved on the outer surface of the threaded rod 33, and the first fixing block 31 and the threaded rod 33 are slidably connected. The outer surface of the threaded rod 33 is sleeved with a nut 34, which is threadedly connected to the threaded rod 33.
[0021] In this embodiment, by setting a connecting mechanism 3, which can be used in conjunction with the top cover 21, the top cover 21 can be stably installed on the top of the defoamer 1. At the same time, a fixing block 31 and a threaded rod 33 are set, and the fixing block 31 can be sleeved on the outer surface of the threaded rod 33. With the cooperation of the fixing block 31 and the threaded rod 33, the top cover 21 can continuously move closer to the top surface of the defoamer 1, thereby squeezing and deforming the rubber pad 22. At the same time, with the cooperation of the nut 34, the top cover 21 can tightly squeeze the rubber pad 22, so that the connection between the top cover 21 and the defoamer 1 remains sealed.
[0022] Working principle: like Figures 1-3As shown, in use, the PET film raw material to be processed can first be put into the defoamer 1. Then, the rubber pad 22 is installed inside the sealing groove opened on the top of the defoamer 1. At this time, the top cover 21 is installed, and the fixing block 31, which is fixedly connected to the top cover 21, can be sleeved on the outer surface of the threaded rod 33. Then, the nut 34 is threadedly connected to the threaded rod 33, so that the top cover 21 can continuously approach the defoamer 1 and compress the rubber pad 22, causing the rubber pad 22 to deform until the top cover 21 can seal the top of the defoamer 1 with the cooperation of the rubber pad 22. Then, the defoamer 1 is started, and the defoamer 1 can agitate and dry the PET film raw material. Then, the motor 26 is started. At this time, the motor 26 will... The fan blades 27 rotate at high speed, which exhausts the air inside the fixed tube 23, creating a negative pressure inside the tube. This allows the water vapor inside the defoamer 1 to be exhausted by the suction mechanism 2, enabling the PET film material to be dried quickly. The temperature and humidity of the PET film material are constantly monitored by the temperature and humidity detector 24. When the temperature and humidity of the PET film material are suitable, the cover 29 can be threaded onto the fixed tube 23. With the cooperation of the screw block 201, the cover 29 can be smoothly fitted onto the outer surface of one end of the fixed tube 23, sealing the port of the fixed tube 23. Then, the PET film material is fed into the tube, and at the same time, the PET film material is sealed and packaged to ensure that no air bubbles will be generated during subsequent use.
[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
