Description

Technical Field

[0001] This utility model relates to the field of hopper mixer technology, and in particular to a double-column hopper mixer. Background Technology

[0002] A hopper mixer is a device used to mix solid particles, powders, and other materials. It offers advantages such as large mixing batch size, reliable force distribution, and stable operation, and is widely used in the pharmaceutical, chemical, and food industries. A hopper mixer typically consists of a base, drive system, control system, and mixing hoppers. During operation, materials are added to the hopper and the lid is locked. The mixing time and speed are set according to process requirements. After the control system is activated, the rotating body (mixing hopper) begins to rotate.

[0003] However, existing hopper mixers generally have a certain height. If the hopper is too high, it is not only less efficient when feeding materials manually, but also poses certain safety hazards. This is especially inconvenient for feeding smaller particles or powdery materials.

[0004] The information disclosed above in this background section is merely for enhancing understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] The main objective of this invention is to provide a double-column hopper mixer that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A double-column hopper mixer includes a hopper mixer, a support base is fixedly installed at the lower rear end of the hopper mixer, an adjustment groove is opened at the middle of the upper end of the support base, a fixed frame is slidably installed at the upper end of the adjustment groove, a controller is fixedly installed at the middle of the right end of the fixed frame, a feeding device is inserted and fixedly installed at the front end of the fixed frame, and an adjustment device is inserted and fixedly installed at the rear end of the adjustment groove.

[0008] Preferably, the left and right inner walls of the fixed frame are provided with sliding grooves, and a hydraulic cylinder is fixedly installed on the lower inner wall of the fixed frame. A slider is fixedly installed at the output end of the hydraulic cylinder, and the slider is slidably installed in the two sliding grooves. A fixing groove is provided at the front end of the slider. By pushing the slider up and down within the fixed frame with the hydraulic cylinder, the conveying cylinder is adjusted up and down accordingly, so that the discharge port can be inserted into the inlet of the hopper mixer, preventing the conveyed powder or granular material from rolling out, thereby improving the stability of the device's discharge.

[0009] Preferably, the feeding device includes a conveyor cylinder, a servo motor is fixedly installed at the rear end of the conveyor cylinder, a conveyor shaft is fixedly installed at the output end of the servo motor, the conveyor shaft is rotatably mounted on the conveyor cylinder, and a spiral conveying blade is fixedly installed on the outer surface of the conveyor shaft. A feed inlet is fixedly installed at the rear upper end of the conveyor cylinder, and a discharge outlet is fixedly installed at the front lower end of the conveyor cylinder. The conveyor cylinder is fixedly mounted on the slider through a fixing groove. The servo motor drives the conveyor shaft and the spiral conveying blade to rotate inside the conveyor cylinder, at which time the spiral conveying blade can push the input material to the discharge outlet for discharge.

[0010] Preferably, the adjusting device includes a second servo motor, with a threaded rod fixedly mounted on the output end of the second servo motor. The threaded rod is rotatably mounted in the adjusting groove, and an adjusting block is mounted on the outer surface of the threaded rod. The second servo motor is inserted and fixedly mounted at the rear end of the adjusting groove. The second servo motor drives the threaded rod to rotate within the adjusting groove, causing the adjusting block on the threaded rod to slide within the groove, thereby moving and adjusting the fixed frame and the conveying cylinder so that the discharge port at the lower end of the conveying cylinder is precisely aligned with the inlet of the hopper mixer.

[0011] Preferably, the conveying cylinder is designed to be inclined, and the discharge port is vertically aligned with the inlet position of the hopper mixer.

[0012] Preferably, the adjusting block is slidably installed in the adjusting groove, and the adjusting block is fixedly installed at the lower end of the fixed frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the hopper mixer is needed to mix materials such as granules with granules, granules with powder, or powder with powder in medicine, the second servo motor on the adjusting device first drives the threaded rod to rotate in the adjusting groove. At this time, the adjusting block on the threaded rod slides in the adjusting groove, thereby driving the fixed frame and the conveying cylinder to move and adjust so that the discharge port at the lower end of the conveying cylinder is just aligned with the inlet on the hopper mixer. Then, the hydraulic cylinder pushes the slider to slide up and down in the fixed frame, thereby driving the conveying cylinder to move up and down, so that the discharge port can be inserted into the inlet on the hopper mixer, preventing the conveyed powder or granular materials from rolling out, thereby improving the stability of the device's feeding.

[0015] 2. Pour the materials to be mixed into the conveying cylinder through the feed inlet. At this time, the No. 1 servo motor drives the conveying shaft and the spiral conveying blade to rotate inside the conveying cylinder. The spiral conveying blade can push the input materials to the discharge port for discharge. Attached Figure Description

[0024] like Figures 1-4As shown, a double-column hopper mixer includes a hopper mixer 1. A support base 5 is fixedly installed at the lower rear end of the hopper mixer 1. An adjustment groove 6 is opened in the middle of the upper end of the support base 5. A fixed frame 2 is slidably installed on the upper end of the adjustment groove 6. A controller 7 is fixedly installed in the middle of the right end of the fixed frame 2. A feeding device 3 is inserted and fixedly installed at the front end of the fixed frame 2. An adjustment device 4 is inserted and fixedly installed at the rear end of the adjustment groove 6.

[0025] The fixed frame 2 has grooves 21 on both its left and right inner walls. A hydraulic cylinder 20 is fixedly installed on the lower inner wall of the fixed frame 2. A slider 22 is fixedly installed at the output end of the hydraulic cylinder 20. The slider 22 is slidably installed in the two grooves 21, and a fixing groove 23 is opened at the front end of the slider 22. The hydraulic cylinder 20 pushes the slider 22 to slide up and down in the fixed frame 2, thereby driving the conveying cylinder 30 to adjust up and down, so that the discharge port 35 can be inserted into the inlet of the hopper mixer 1, preventing the conveyed powder or granular material from rolling out, thus improving the stability of the device's discharge. The hopper mixer 1 is a HGD fixed hopper mixer.

[0026] The feeding device 3 includes a conveyor cylinder 30. A servo motor 31 is fixedly installed at the rear end of the conveyor cylinder 30. A conveyor shaft 32 is fixedly installed at the output end of the servo motor 31. The conveyor shaft 32 is rotatably mounted on the conveyor cylinder 30, and a spiral conveying blade 33 is fixedly installed on the outer surface of the conveyor shaft 32. A feed inlet 34 is fixedly installed at the rear upper end of the conveyor cylinder 30, and a discharge outlet 35 is fixedly installed at the front lower end of the conveyor cylinder 30. The conveyor cylinder 30 is fixedly installed on the slider 22 through a fixing groove 23. The conveyor cylinder 30 is designed with an inclination, and the discharge outlet 35 corresponds vertically to the inlet position of the hopper mixer 1. The servo motor 31 drives the conveyor shaft 32 and the spiral conveying blade 33 to rotate inside the conveyor cylinder 30. At this time, the spiral conveying blade 33 can push the input material to the discharge outlet 35 for discharge.

[0027] The adjustment device 4 includes a second servo motor 40, with a threaded rod 41 fixedly mounted on the output end of the second servo motor 40.

The second servo motor 40 drives the threaded rod 41 to rotate in the adjustment groove 6. At this time, the adjustment block 42 on the threaded rod 41 slides in the adjustment groove 6, thereby driving the fixed frame 2 and the conveying cylinder 30 to move and adjust, so that the discharge port 35 at the lower end of the conveying cylinder 30 can be aligned with the inlet on the hopper mixer 1.

[0028] It should be noted that this utility model is a double-column hopper mixer. When the hopper mixer 1 is used to mix materials such as granules with granules, granules with powder, or powders with powders in medicine, the second servo motor 40 on the adjusting device 4 first drives the threaded rod 41 to rotate in the adjusting groove 6. At this time, the adjusting block 42 on the threaded rod 41 slides in the adjusting groove 6, thereby driving the fixed frame 2 and the conveying cylinder 30 to move and adjust, so that the discharge port 35 at the lower end of the conveying cylinder 30 can be aligned with the inlet on the hopper mixer 1. Then, the hydraulic cylinder... 20 pushes the slider 22 to slide up and down within the fixed frame 2, thereby driving the conveying cylinder 30 to adjust up and down, so that the discharge port 35 can be inserted into the inlet of the hopper mixer 1, preventing the conveyed powder or granular material from rolling out, thus improving the stability of the device's discharge. Then, the material to be mixed is poured into the conveying cylinder 30 through the feed port 34. At this time, the first servo motor 31 drives the conveying shaft 32 and the spiral conveying blade 33 to rotate within the conveying cylinder 30. The spiral conveying blade 33 can then push the input material to the discharge port 35 for discharge.
