Technical Field

[0001] The utility model relates to the technical field of PVB resin production, in particular to a powder washing pot for PVB resin that can be randomly inspected. Background Technique

[0002] PVB resin, whose full name is polyvinyl butyral, is an important polymer material with broad application prospects. PVB resin is a resin that is easy to adhere to various different surfaces, with high toughness and high elasticity. It has strong binding force, high optical clarity, and the characteristics of being non-toxic, odorless, and non-corrosive. PVB resin is prepared by reacting polyvinyl alcohol with butyraldehyde and is produced from petroleum. During the production process of PVB resin, as one of the key equipment, the performance of the powder washing pot directly affects the product quality and production efficiency. As a high-performance adhesive, PVB resin is widely used in fields such as automotive safety glass, building sound insulation materials, and electronic packaging, and its quality stability is particularly important.

[0003] In the traditional PVB resin powder washing process, PVB resin powder is usually directly put into the washing pot and stirred and washed with clean water. Currently, this kind of washing pot design often lacks an effective random inspection mechanism and cannot randomly inspect the washing effect of PVB resin powder during the washing process, making it difficult to ensure the batch consistency of products. Therefore, we need to propose a powder washing pot for PVB resin that can be randomly inspected. Content of the Utility Model

[0004] The purpose of the utility model is to provide a powder washing pot for PVB resin that can be randomly inspected, aiming to solve the problem in the prior art that there is a lack of an effective random inspection mechanism and it is impossible to randomly inspect the washing effect of PVB resin powder during the washing process, thus making it difficult to ensure the batch consistency of products.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3 , the present invention provides a technical solution:

[0021] A powder washing pot for randomly inspecting PVB resin includes a washing pot body 1. A feed pipe 2 is fixedly communicated with the top of the washing pot body 1. A stirring assembly 3 for fully cleaning the PVB resin is arranged inside the washing pot body 1. A through groove 4 is opened on the outer wall of the washing pot body 1. A fixed cylinder 5 is fixedly embedded inside the through groove 4. A sampling assembly 6 for randomly sampling the PVB resin during cleaning is arranged inside the inner cavity of the fixed cylinder 5. And the bottom end of the sampling assembly 6 penetrates through the fixed cylinder 5 and is located inside the washing pot body 1. By setting the cooperation of the washing pot body 1, the feed pipe 2 and the stirring assembly 3, the function of fully cleaning the PVB resin inside the washing pot body 1 is achieved. When the stirring assembly 3 cleans the PVB resin inside the washing pot body 1, by opening the through groove 4 on the outer wall of the washing pot body 1 and coordinating with the cooperation of the fixed cylinder 5 and the sampling assembly 6, the PVB resin during the cleaning process can be randomly sampled, and then a professional detection device is used to detect the sample, so as to achieve the effect of randomly inspecting the PVB resin inside the washing pot body 1, thereby ensuring the consistency of the PVB resin products in the same batch;

[0022] The sampling assembly 6 includes a top cover 601. The top cover 601 is arranged at the top end of the fixed cylinder 5. A connecting rod 602 is connected to the bottom of the top cover 601. A sampling funnel 603 is fixedly connected to the bottom of the connecting rod 602;

[0023] By adopting the above case, when it is necessary to sample and inspect the PVB resin during cleaning, the top cover 601 can be first disassembled from the top of the fixed cylinder 5, and then the top cover 601 is held by hand, and the sampling funnel 603 is appropriately shaken inside the washing pot body 1. The purpose is to shake off the PVB resin that has already been inside the sampling funnel 603 during cleaning, and then re-sample to ensure the randomness of sampling;

[0024] A sealing bump 7 is provided on the inner top of the top cover 601. The sealing bump 7 is inserted into the interior of the fixed cylinder 5, and the top end of the connecting rod 602 is fixedly connected to the bottom of the sealing bump 7. By providing the sealing bump 7, the airtightness between the top cover 601 and the fixed cylinder 5 is increased. It should be noted that the fixed cylinder 5 is inclined, with the opening facing upward and being hollow, aiming to ensure that when the top cover 601 is removed, the PVB resin being washed inside the water-washing pot body 1 will not leak out, which is beneficial to ensuring the stability of the powder water-washing pot during use;

[0025] Internal threads 8 are provided on the inner wall of the top cover 601, and external threads 9 adapted to the internal threads 8 are provided on the outer wall of the fixed cylinder 5. The top cover 601 is threadedly connected to the top of the fixed cylinder 5. By providing the internal threads 8 and the external threads 9, it is convenient to disassemble the top cover 601. After a PVB resin sample during cleaning is randomly taken inside the sampling funnel 603, then by holding the top cover 601 by hand, the connecting rod 602 together with the sampling funnel 603 can be taken out, and then a third-party professional testing device can be used to test the PVB resin sample, which can ensure the consistency of the same batch of PVB resin products;

[0026] The stirring assembly 3 includes a rotating rod 301. The top end and the bottom end of the rotating rod 301 are respectively rotatably installed on the inner top and the inner bottom of the water-washing pot body 1. The top end of the rotating rod 301 penetrates through the water-washing pot body 1 and is connected to a driving motor 302. Two groups of stirring paddles 303 are fixedly connected to the outer wall of the rotating rod 301;

[0027] Specifically, by setting the driving motor 302, the rotating rod 301 and the stirring paddles 303 to cooperate, the output shaft of the driving motor 302 can drive the rotating rod 301 to rotate, thereby driving the stirring paddles 303 to rotate, so as to achieve the effect of stirring and cleaning the PVB resin inside the water-washing pot body 1;

[0028] Each group of stirring paddles 303 includes four stirring blades, and a number of groups of through holes 10 are provided on each stirring blade. By providing the through holes 10 on the stirring blades, the through holes 10 on the stirring blades can increase the contact area between the liquid and the PVB resin powder, thereby increasing the cleaning effect of the PVB resin. In addition, when dealing with dense PVB resin, the stirring blades may generate a considerable amount of pressure, and the existence of the through holes 10 can release this pressure, reduce the burden on the stirring blades, and improve the safety of operation;

[0029] The driving motor 302 is fixedly installed at the top of the water-washing pot body 1. One end of the output shaft of the driving motor 302 is fixedly connected to the top end of the rotating rod 301. The driving motor 302 is set as a stepping motor, which has the characteristics of high precision and good stability, and can ensure the accuracy and consistency during the stirring process. By controlling the pulse number and frequency of the stepping motor, the angle and speed of the stirring blade can be precisely controlled, so as to achieve a finer stirring effect. This controllability enables the operator to adjust the stirring intensity according to different process requirements to meet the stirring needs of different PVB resins.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
