Description

Technical Field

[0001] The utility model relates to the field of blending and modification, in particular to a special resin blending and modification device for steel-plastic composite belts. Background Art

[0002] The special resin for steel-plastic composite belt is ethylene-acrylic acid copolymer. Before producing steel-plastic composite belt, different raw materials need to be added to ethylene-acrylic acid copolymer to blend it and change the characteristics of the raw materials. For example, adding 6-ethoxy-2, HALS, TiO2 and other raw materials during the blending process can improve the anti-aging and corrosion resistance of the resin, thereby increasing the service life of the steel-plastic composite belt.

[0003] During the process of blending and modifying the materials, a stirring device is required to stir them so that the raw materials can be fully mixed. The stirring rod of the traditional stirring device is mostly installed in the center of the stirring barrel and then fixedly connected to the output shaft of the motor. The stirring device can only stir in a single direction during use, and the materials will move synchronously with the direction of the stirring rod during the stirring process. The material will move to the edge under the action of centrifugal force, and it is impossible for the material to return to the center of the material barrel after touching the inner wall of the material barrel, so that the concentration of the material in the center is lower and the concentration in the outer layer is higher, resulting in poor mixing effect during the mixing process, such as a stirring device for stirring paint with patent publication number CN114669235A.

[0004] The planetary mixers commonly seen on the market have an internal agitator that revolves around the axis of the barrel while also rotating at high speed around its own axis at different speeds, which can improve the mixing effect on the materials. However, the agitator can only revolve in a circular direction when operating, while the stirring rod rotates. The revolution motion trajectory of the stirring rod is a circular structure and does not pass through the axis of the mixing barrel. The material at the axis cannot be stirred. The material at the axis of the mixing barrel can only be stirred by centrifugal force. The stirring rod cannot move from the center of the mixing barrel to the edge, resulting in poor mixing effect. Utility Model Content

[0005] The main purpose of the utility model is to provide a resin blending and modification device dedicated to steel-plastic composite belts, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A resin blending and modification device for steel-plastic composite belts, comprising a mixing barrel, a motor is fixedly mounted on the upper end of the mixing barrel, a driving gear is fixedly mounted on the output shaft of the motor, and a driven gear meshing with the driving gear is rotatably mounted on the upper end of the mixing barrel;

[0008] A belt is installed on the connecting shaft of the driven gear, a plurality of transmission shafts are fixedly installed on the upper end of the mixing barrel, and the other end of the belt is installed on the circumferential surface of the transmission shaft;

[0009] A rotating rod is rotatably installed on the circumferential surface of the conveying shaft, a stirring rod is slidably installed on the inner side of the other end of the rotating rod, a passive gear is fixedly installed on the upper end of the stirring rod, a plurality of radially arranged positioning grooves are opened on the upper end of the stirring barrel, the upper end of the passive gear is located inside the positioning groove and can move in the positioning groove; a rack is fixedly installed on one side wall of the interior of the positioning groove, and the passive gear is meshed with the rack.

[0010] Furthermore, a discharge port is fixedly installed at the lower end of the mixing barrel.

[0011] Furthermore, the passive gear can rotate inside the positioning slide groove.

[0012] Furthermore, a first sliding groove is formed at one end of the rotating rod away from the transmission shaft.

[0013] Furthermore, the upper end of the passive gear is slidably mounted on the inner side of the first sliding groove.

[0014] Furthermore, the height of the rotating rod is lower than the height of the belt.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The motor of the utility model can drive the driving gear to rotate, and when the driving gear rotates, it can drive the driven gear to rotate synchronously, so that the driven gear can drive the transmission shaft to rotate, and the transmission shaft can rotate with the rotating rod, so that the rotating rod drives the passive gear and the stirring rod to rotate, and the stirring rod can move in the positioning chute, that is, move along the radial direction of the mixing barrel. At the same time, under the action of the rack, the passive gear can rotate in the positioning chute. When the passive gear rotates, it can drive the stirring rod to rotate, and stir and mix the materials in the mixing barrel.

[0017] When the stirring rod moves, there are two states. The first state is that the stirring rod moves from the center of the stirring barrel to the edge. When the stirring rod moves to the edge, it can drive the material at the center to the edge. The second state is that the stirring rod moves from the edge to the center of the stirring barrel. When the stirring rod moves to the center, it can drive the material at the edge to the center of the stirring barrel. In the two states, the stirring between the material at the center of the stirring barrel and the material at the edge is achieved, thereby improving the mixing effect of the materials.

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] As shown in the figure, this embodiment provides a resin blending and modifying device for steel-plastic composite belts, including a mixing barrel 1, and a discharge port 11 is provided on the inner bottom surface of the mixing barrel 1, and the discharge port 11 can allow the blended material to flow out. Figure 2 Three support rods are fixedly installed on the top of the mixing barrel 1, and a vertical motor 2 (motor 2 is a forward and reverse motor) is fixedly installed at the intersection of the support rods. A driving gear 21 is fixedly installed on the output shaft of the motor 2, and the forward and reverse motor can drive the driving gear 21 to rotate forward and reverse, as shown in FIG. Figure 3 The top of the mixing barrel 1 is located at the edge of the driving gear 21 and is rotatably mounted with three driven gears 22. The driven gears 22 mesh with the driving gear 21 and can drive the driven gears 22 to rotate synchronously when the driving gear 21 rotates. Figure 4 shown.

[0025] The driven gear 22 has a structure in which gears are arranged at both ends, a connecting shaft is located in the middle, and a belt 23 is installed on the circumferential surface of the connecting shaft.

[0026] Three corresponding conveying shafts 24 are fixedly installed on the top of the mixing barrel 1, and the other end of the belt 23 is embedded in the circumferential surface of the conveying shaft 24. Figure 4 shown.

[0027] When the driven gear 22 rotates, the belt 23 can be driven to move synchronously, and the belt 23 can drive the transmission shaft 24 to rotate synchronously. Figure 4 shown.

[0028] A rotating rod 25 is fixedly mounted on the conveying shaft 24. When the conveying shaft 24 rotates, the rotating rod 25 can move in a fan-shaped manner (the height of the rotating rod 25 is slightly lower than the height of the belt 23 so as not to affect the belt 23). Figure 4 shown.

[0029] The other end of the rotating rod 25 is provided with a first slide groove 251, and a stirring rod 31 is arranged inside the first slide groove 251. The bottom body of the stirring rod 31 is located inside the stirring barrel 1, and stirring teeth arranged evenly are fixedly installed on the outside of the stirring rod 31. A passive gear 3 is fixedly installed on the top of the stirring rod 31, and the top of the passive gear 3 is slidably installed on the inner side of the first slide groove 251. The upper end of the passive gear 3 is provided with an annular groove, and the top diameter of the passive gear 3 is larger than the first slide groove 251, so as to support the passive gear 3 and prevent the gear from falling from the first slide groove 251. Figure 4 shown.

[0030] A radial positioning groove 12 is provided on the top of the mixing barrel 1. The positioning groove 12 points to the axis of the mixing barrel. A rack is fixedly installed on one of the side walls of the positioning groove 12. The driven gear 3 is located in the positioning groove 12 and meshes with the rack. Figure 3 As shown. When the rotating rod 25 performs a fan-shaped motion, the rotating rod 25 can carry the driven gear 3 to perform a linear reciprocating motion inside the positioning slot 12. However, during the movement, the driven gear 3 can rotate under the action of the rack inside the positioning slot 12, so that the driven gear 3 can rotate clockwise when close to the motor 2, and can rotate counterclockwise when away from the motor 2, that is, the driven gear 3 can roll in the positioning slot 12. Thereby, the stirring rod 31 can rotate synchronously, so that the stirring rod 31 can approach or move away from the center position of the stirring barrel 1.

[0031] The working principle is as follows: during operation, the motor 2 drives the driving gear 21 to rotate, and when the driving gear 21 rotates, it can drive the driven gear 22 to rotate synchronously.

[0032] When the driven gear 22 rotates, it can drive the belt 23, so that the belt 23 can drive the transmission shaft 24 to rotate, and the transmission shaft 24 can drive the rotating rod 25 to perform a fan-shaped motion, so that the rotating rod 25 drives the driven gear 3 to perform a linear reciprocating motion inside the positioning slide groove 12.

[0033] During the movement of the passive gear 3, it can rotate under the action of the rack inside the positioning groove 12, so that the passive gear 3 can make a circular motion with the stirring rod 31, and then the stirring rod 31 can be close to or away from the center of the mixing barrel 1, so that the stirring rod 31 can stir from the edge to the center position, and stir from the center position to the edge position, thereby improving the raw material blending effect.

[0034] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be determined by the attached claims and their equivalents.
