Description

Technical Field

[0001] This utility model relates to the field of resin mixing technology, and more specifically, to a resin mixing machine. Background Technology

[0002] Resin generally refers to an organic polymer that softens or melts when heated, tends to flow under external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for plastic products is called a resin. Epoxy resin is a type of resin; it is a polymer that generally refers to organic polymers containing two or more epoxy groups in their molecules. With a few exceptions, their relative molecular mass is not high. The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain. These epoxy groups can be located at the ends, in the middle, or in a cyclic structure. Because of the active epoxy groups in their molecular structure, they can undergo cross-linking reactions with various types of curing agents to form insoluble polymers with a three-dimensional network structure.

[0003] A search revealed, for example, a Chinese patent application with publication number CN219522647U discloses an epoxy resin mixer. This mixer utilizes a mixing hopper, baffles, connecting holes, a drive motor, a mounting bracket, a PLC controller, a mounting groove, a stepper motor, a lead screw, a moving plate, threaded holes, connecting columns, a fixing block, a stirring column, a cleaning ring, and a stirring plate in a coordinated manner. This facilitates the cleaning of epoxy resin adhering to the inner wall of the mixing hopper, ensuring a suitable mixing environment for subsequent epoxy resin applications and preventing a large accumulation of epoxy resin on the inner wall of the mixing hopper from affecting subsequent epoxy resin mixing.

[0004] However, the above solution requires a stepper motor and lead screw to raise the baffle and lift the cleaning ring to clean the inner wall of the mixing chamber when cleaning the resin inside the mixing chamber. This method is costly. Furthermore, when the resin sticks to the inner wall of the mixing chamber, it is difficult to achieve mixing. As a result, the cleaned resin needs to be processed again, which is quite troublesome. In addition, the above solution discharges the mixed resin through the discharge pipe. The resin has a high viscosity, which results in a slow discharge speed and delays subsequent work. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a resin mixer. The technical problem to be solved is that the cost is high, the cleaned resin needs to be stirred again, and the resin discharge after stirring is slow, which delays subsequent work.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a resin mixer, comprising a mixing tank:

[0007] The upper end of the mixing tank is fixed with a forward and reverse motor via a flange. The output end of the forward and reverse motor passes through the upper end of the mixing tank, and the lower end of the mixing tank is connected to a discharge pipe.

[0008] The output end of the positive and negative motors is equipped with an inner wall cleaning device that can clean the resin inside the mixing tank, which is used to clean the inner wall of the mixing tank while mixing the resin.

[0009] The inner wall cleaning device includes a rotating shaft, which is fixedly installed at the output end of the positive and negative motors. The rotating shaft is located inside the mixing tank, and a first auger blade is fixedly provided on the outer surface of the rotating shaft.

[0010] The inner side of the discharge pipe is equipped with a resin discharge device capable of conveying resin, which is used to transport the resin inside the mixing tank out of the discharge pipe.

[0011] In a preferred embodiment, a plurality of fixing rods are fixedly provided on the outer surface of the rotating shaft, and the same shaftless auger is fixedly provided at the outer end of the plurality of fixing rods, with the outer surface of the shaftless auger in close contact with the inner wall of the mixing tank.

[0012] In a preferred embodiment, a plurality of scraping plates are fixedly provided on the outer surface of the lower end of the rotating shaft, and the outermost end of the scraping plate is in close contact with the inner wall of the lower end of the mixing tank.

[0013] In a preferred embodiment, the resin discharge device includes a discharge chamber located inside the discharge pipe.

[0014] In a preferred embodiment, a connecting shaft is fixedly provided at the lower end of the rotating shaft, and a second auger blade is fixedly provided on the outer surface of the connecting shaft.

[0015] In a preferred embodiment, the outer surface of the second auger blade is in close contact with the inner wall of the discharge chamber.

[0016] In a preferred embodiment, a feed hopper is connected to one side of the mixing tank, a support foot is fixedly provided at the lower end of the mixing tank, and a controller is fixedly provided on one side of the mixing tank.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model uses a forward and reverse motor to drive the rotating shaft to rotate, thereby using the first auger blades to stir and mix the resin in the mixing tank. When the resin is poured into the mixing tank and sticks to the inner wall of the mixing tank, the shaftless auger and the scraper rotate simultaneously, which can scrape the inner wall of the mixing tank. Therefore, stirring and cleaning can be achieved at the same time, avoiding the trouble of later cleaning and avoiding the trouble of secondary mixing of the cleaned resin.

[0019] 2. This utility model uses the reverse rotation of the forward and reverse motors to drive the scraper and shaftless auger to rotate in opposite directions, which can scrape the resin on the inner wall of the upper end of the mixing tank downward and flow into the discharge pipe. When the rotating shaft rotates in the reverse direction, the connecting shaft and the second auger blades can guide the resin to be transported in the discharge pipe, thereby increasing the discharge speed.

Detailed Implementation

[0025] 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 skilled in the art of resin mixing without creative effort are within the scope of protection of the present utility model.

[0026] like Figure 1 and 2 As shown, this utility model provides a resin mixer, including a mixing tank 1: a forward and reverse motor 8 is fixedly installed at the upper end of the mixing tank 1 by a flange, the output end of the forward and reverse motor 8 passes through the upper end of the mixing tank 1, a discharge pipe 5 is connected to the lower end of the mixing tank 1, a feed hopper 4 is connected to one side of the mixing tank 1, a support foot 6 is fixedly installed at the lower end of the mixing tank 1, and a controller 7 is fixedly installed on one side of the mixing tank 1.

[0027] In order to achieve simultaneous mixing and cleaning, avoid the trouble of later cleaning, and avoid the trouble of re-mixing the cleaned resin, the output end of the positive and negative motor 8 is equipped with an inner wall cleaning device 2 that can clean the resin on the inner wall of the mixing tank 1, which is used to clean the inner wall of the mixing tank 1 while mixing the resin.

[0028] like Figure 3 As shown, the inner wall cleaning device 2 includes a rotating shaft 21, which is fixedly installed at the output end of the positive and negative motor 8. The rotating shaft 21 is located inside the mixing tank 1. A first auger blade 24 is fixedly installed on the outer surface of the rotating shaft 21. Multiple fixing rods 22 are fixedly installed on the outer surface of the rotating shaft 21. The same shaftless auger 23 is fixedly installed at the outer end of the multiple fixing rods 22. The outer surface of the shaftless auger 23 is in close contact with the inner wall of the mixing tank 1. Multiple scraper plates 25 are fixedly installed on the lower outer surface of the rotating shaft 21. The outermost end of the scraper plate 25 is in close contact with the lower inner wall of the mixing tank 1. The rotating shaft 21 is driven to rotate by the positive and negative motor 8, so that the resin in the mixing tank 1 can be stirred and mixed by the first auger blade 24. When the resin is poured into the mixing tank 1 and sticks to the inner wall of the mixing tank 1, the shaftless auger 23 and the scraper plate 25 can scrape the inner wall of the mixing tank 1 by rotating simultaneously. Therefore, stirring and cleaning can be achieved at the same time, avoiding the trouble of later cleaning and avoiding the trouble of secondary mixing of the cleaned resin.

[0029] Furthermore, in order to increase the resin discharge speed, a resin discharge device 3 is provided inside the discharge pipe 5 to transport the resin from the mixing tank 1 out of the discharge pipe 5.

[0030] like Figure 4 As shown, the resin discharge device 3 includes a discharge chamber 31, which is located inside the discharge pipe 5. A connecting shaft 32 is fixedly provided at the lower end of the rotating shaft 21. A second auger blade 33 is fixedly provided on the outer surface of the connecting shaft 32. The outer surface of the second auger blade 33 is in close contact with the inner wall of the discharge chamber 31. By rotating the forward and reverse motors 8 in opposite directions, the scraper 25 and the shaftless auger 23 are driven to rotate in opposite directions, which can scrape the resin on the upper inner wall of the mixing tank 1 downward and flow into the discharge pipe 5. When the rotating shaft 21 rotates in opposite directions, the connecting shaft 32 and the second auger blade 33 can guide the resin to be transported in the discharge pipe 5, thereby increasing the discharge speed.

[0031] The working principle is as follows: When using this utility model, the resin to be mixed is poured into the feed hopper 4, and the feed hopper 4 is used to send the resin into the utility model. The controller 7 controls the rotation of the forward and reverse motors 8. The inner wall cleaning device 2 can simultaneously clean the inner wall of the utility model and mix the resin. After the resin in the utility model is mixed, the controller 7 controls the forward and reverse motors 8 to rotate in the opposite direction, so that the resin in the utility model is transported to the discharge pipe 5 by the resin discharge device 3, and the discharge speed is increased. Overall, the practicality of this utility model is improved, and the use of extra motors is reduced, thus reducing the cost.

[0032] In addition, it is worth noting that the control process of electrical equipment such as the forward and reverse motor 8 in this utility model is realized by the controller 7. The controller 7 is powered by an external power supply. The control circuit and structure of the controller 7 are mature existing technologies, so they will not be described in detail in this utility model.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
