[0002] A dry mixer is a device used to mix and stir various materials. It is widely used in the chemical, food, pharmaceutical and other industries. Its working principle is to mix and stir the materials through mechanical force to achieve a uniform mixing effect. Common dry mixers include double cone dry mixers, vertical dry mixers and other different types.

[0003] The dry mixer of the prior art has the following disadvantages during use:

[0004] ① On the one hand, when the power is off or the power is off, the rubber in the dry mixer stays in the cavity. After the rubber solidifies, it is difficult to clean. If the rubber is ejected by reversing the high-speed motor of the device itself, the motor will heat up due to the heavy load at this time, causing greater damage;

[0005] ② The second aspect is to directly set a feed hopper at the feed inlet to realize the input of rubber. The rubber is continuously fed into the main body of the dry mixer, resulting in low mixing efficiency during processing and easy burden on the mixing. Therefore, a dry mixer that can be powered off and return materials is needed. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0024] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0025] Example

[0026] ① On the one hand, when the power is off or the power is off, the rubber in the dry mixer stays in the cavity. After the rubber solidifies, it is difficult to clean. If the rubber is ejected by reversing the high-speed motor of the device itself, the motor will heat up due to the heavy load at this time, causing greater damage;

[0027] ② The second aspect is that a feed hopper 4 is directly set at the feed inlet to realize the input of the rubber material, and the rubber material is continuously fed into the dry mixer body 1, which leads to low mixing efficiency of the dry mixer during processing and easily brings a burden to the mixing;

[0028] To do this, see Figure 1-2 The utility model provides a dry mixer capable of withdrawing materials after power failure, comprising:

[0029] A high-speed motor 2 is fixedly mounted on the dry mixer body 1, and the high-speed motor 2 is connected to a drive shaft 22 through a belt transmission structure 21, and the drive shaft 22 is rotatably connected to the dry mixer body 1. An independent power mechanism 3 mounted on the dry mixer body 1 is also provided on one side of the high-speed motor 2. A feed hopper 4 is fixedly connected to the top feed port of the dry mixer body 1, and an intermittent feeding structure 5 and an adjustment structure 6 mounted on the feed hopper 4 are provided at the feed port;

[0030] The independent power mechanism 3 can facilitate the reverse material return;

[0031] The intermittent feeding structure 5 enables the material in the feeding hopper 4 to intermittently fall into the dry mixer body 1 for processing;

[0032] The regulating structure 6 can adjust the amount of material dropped in each time.

[0033] Further Figure 1-2 As shown, it is worth explaining in detail that in order to enable the reverse return of the rubber material when the dry mixer body 1 is powered off or out of power, an independent power mechanism 3 is provided, including a large sprocket 31 fixedly connected to the outer side of the extension portion at one end of the drive shaft 22, and the large sprocket 31 is connected to a small sprocket 33 through a chain 32. The small sprocket 33 is fixedly connected to the outer side of the output shaft of the reduction motor 34, and the reduction motor 34 is fixedly connected to the dry mixer body 1.

[0034] Among them, the small sprocket 33 drives the large sprocket 31 through the chain 32, so that the rotation speed is small and the torque is large, so that the reverse material return is realized and the heat burden of the reduction motor directly reversing the material return is reduced.

[0035] Further Figure 1-2 As shown, it is worth explaining in detail that, in order to enable the rubber material in the feed hopper 4 to intermittently fall into the dry mixer body 1 for processing, an intermittent feeding structure 5 is provided, including a baffle plate 51 movably inserted at the bottom opening of the feed hopper 4, one end of the baffle plate 51 is in contact with the inner wall of the feed hopper 4, and the other end is provided with a transmission channel 52, the transmission channel 52 is movably sleeved on the outer side of a transmission column 53, the bottom end of the transmission column 53 is fixedly connected to the top edge of a turntable 54, the turntable 54 is fixedly connected to the outer side of the output shaft of a driving motor 55, and the driving motor 55 is fixedly connected to the outer wall of the dry mixer body 1 through a connecting seat.

[0036] Among them, the length of the transmission channel 52 is larger than the diameter of the turntable 54, and the diameter of the transmission column 53 is larger than the width of the transmission channel 52. When the turntable 54 rotates, a gap will be opened between the end of the baffle plate 51 away from the transmission channel 52 and the inner wall of the side of the feed hopper 4 close to the adjustment structure 6, so that the rubber can fall in intermittently.

[0037] Further Figure 1-2As shown, it is worth explaining in detail that in order to make the width of the above-mentioned gap adjustable so as to meet the adjustment of different intermittent feed amounts, an adjustment structure 6 is provided, including an adjustment plate 61 sliding on the inner side of the feed hopper 4, and the vertical section of the adjustment plate 61 is an inverted isosceles trapezoidal structure. The bottom end of the adjustment plate 61 is in contact with the top end of the baffle plate 51, and two symmetrically arranged movable rods 62 are fixedly connected to the side wall of the adjustment plate 61 away from the transmission channel 52. The two movable rods 62 are movably inserted in the feed hopper 4, and a hand screw 63 threadedly connected to the feed hopper 4 is provided between the two movable rods 62, and one end of the hand screw 63 is rotatably connected to the adjustment plate 61.

[0038] Among them, when the side wall of the adjustment plate 61 is away from the transmission channel 52 and fits against the inner wall of the feed hopper 4, the baffle plate 51 reciprocates, so that the expanded gap is the largest, and the feed amount is maximized, otherwise it is minimized, because the distance of the reciprocating forward and backward movement of the baffle plate 51 is fixed.

[0039] In summary: when using the dry mixer with power-off and material return, especially when the dry mixer main body 1 is shut down or powered off, the reverse speed ratio of the reduction motor can be used to realize reverse material return, so as to solve the problem that the rubber material in the dry mixer main body 1 stays in the cavity when the power is off or the power is out, and it is difficult to clean the rubber material after solidification. In addition, by starting the drive motor 55, the turntable 54 is rotated, thereby cooperating with the function of the transmission column 53 and the transmission channel 52, so that the rubber material above the baffle plate 51 can intermittently fall into the dry mixer main body 1 from the expanded gap for processing, effectively solving the problem of the rubber material entering the dry mixer main body 1 continuously at one time for processing, greatly improving the efficiency of stirring and mixing, and reducing the burden of the dry mixer main body 1 during processing. In addition, by rotating the hand-tightening screw 63, the adjustment plate 61 can be moved in the direction of the transmission channel 52. The closer it is to the transmission channel 52, the less material is intermittently entering, and vice versa. Therefore, it can be adjusted and used according to different feeding conditions.
