Description

Technical Field

[0001] The utility model relates to the technical field of ribbon mixers, in particular to an environmentally friendly ribbon mixer. Background Art

[0002] Ribbon mixers are generally used for mixing sticky or cohesive powders and granules, as well as for adding liquids and paste-like materials to powders and granules. At the same time, due to the difficulty in cleaning sticky materials, they are suitable for mixing in situations where production is large and varieties are not frequently changed.

[0003] The patent with publication number CN221752942U in the prior art discloses a screw ribbon mixer. By setting a scraping component, the scraping component can scrape off the medicine attached to the inner wall of the barrel, thereby improving the discharge effect of the barrel; by setting a driving component, it can drive the scraping component to rotate along with the screw ribbon shaft, thereby realizing the work of the scraping component. However, when adding materials into the barrel, all the materials will accumulate directly under the feeding pipe, which will prolong the time required for the equipment to completely mix the materials, affecting the mixing efficiency of the equipment. For this reason, we propose an environmentally friendly screw ribbon mixer. Utility Model Content

[0012] Beneficial effects

[0013] The utility model provides an environmentally friendly ribbon mixer. Compared with the existing technology, it has the following beneficial effects:

[0014] 1. This environmentally friendly ribbon mixer, when in use, can drive the control rod and worm to rotate by turning the adjustment knob. The rotation of the worm will drive the worm wheel and one of the horizontal rotating shafts to rotate synchronously. At this time, with the cooperation of the two linked gears, the other horizontal rotating shaft can be driven to rotate in the same direction or in opposite directions at the same time, and then the two guide plates can be driven to rotate in the same direction or in opposite directions. As the rotation angle of the guide plates changes, the materials will be guided to fall at different positions in the U-shaped mixing bin, so that the materials can be evenly spread in the U-shaped mixing bin, effectively reducing the time required to completely mix the materials and improving the mixing efficiency of the equipment.

[0015] 2. This environmentally friendly ribbon mixer is equipped with an automatic sealing component. When material is added to the feed port, the material will squeeze the sealing baffle and move downward under the action of gravity to avoid it. When the material is added, the elastic force of the first spring will squeeze and push the sealing baffle upward to automatically reset, thereby sealing the feed port to prevent dust from flying around, making it more environmentally friendly when used.

[0016] 3. This environmentally friendly ribbon mixer, when the unlocking block is pulled, the locking rod will be driven to move out of the locking hole, and the adjusting knob will be loosened. When the unlocking block is loosened, the elastic force of the second spring will squeeze the reset baffle to drive the locking rod to automatically reset and insert into the locking hole, so that the adjusting knob is locked and cannot be rotated. This can effectively reduce the rotation of the guide plate due to accidental touching of the adjusting knob during use, and is stable and reliable when used. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 4The utility model provides a technical solution: an environmentally friendly ribbon mixer, comprising a U-shaped mixing chamber 1, a stirring motor 2 fixedly provided on the side of the U-shaped mixing chamber 1, an output end of the stirring motor 2 extending into the U-shaped mixing chamber 1 and fixedly installed with a ribbon stirring blade 3, when the stirring motor 2 is started, the ribbon stirring blade 3 is driven to rotate, thereby stirring and mixing the materials in the U-shaped mixing chamber 1;

[0024] A feed port 4 is fixedly provided on the top of the U-shaped mixing bin 1, and a discharge port is fixedly provided on the bottom of the U-shaped mixing bin 1. Two horizontal rotating holes are provided on the inner walls on both sides away from each other of the feed port 4, and a horizontal rotating shaft 5 is installed in each two corresponding horizontal rotating holes to rotate together. A guide plate 6 adapted to the feed port 4 is fixedly installed on the two horizontal rotating shafts 5, and a protective box 7 is fixedly installed on the side of the feed port 4. A rotating hole is provided on the top of the protective box 7, and a control rotating rod 8 is rotatably installed in the rotating hole. A worm 9 is fixedly installed on the bottom end of the control rotating rod 8, and a worm gear 10 is fixedly installed on one end of one of the horizontal rotating shafts 5, which is engaged with the worm 9. The ends of the two horizontal rotating shafts 5 are fixedly installed with linkage gears 12, and the two linkage gears 12 are engaged with each other. An adjusting knob 11 is fixedly installed on the top of the control rotating rod 8, and an automatic sealing component is installed in the feed port 4.

[0025] With the above structure, when the adjustment knob 11 is rotated, the control rod 8 will be driven to rotate. The rotation of the control rod 8 will drive one of the horizontal rotating shafts 5 to rotate synchronously through the worm 9 and the worm wheel 10. The rotation of one of the horizontal rotating shafts 5 will drive the other horizontal rotating shaft 5 to rotate in the same direction or in the opposite direction at the same time through the two interlocking gears 12, and then drive the two guide plates 6 to rotate in the same direction or in the opposite direction together. As the rotation angle of the guide plate 6 is different, the material will be guided to fall at different positions in the U-shaped mixing bin 1, so that the material can be evenly spread in the U-shaped mixing bin 1, effectively reducing the time required to completely mix the material and improving the mixing efficiency of the equipment.

[0026] like Figure 2 and Figure 3As shown, the automatic sealing assembly includes a fixed plate 13 fixedly mounted on the inner wall of the side of the feed port 4, and inclined guide plates fixedly mounted on the inner walls of the feed port 4 on both sides away from each other. The top of the fixed plate 13 is evenly provided with multiple vertical sliding holes, and vertical slide rods 14 are slidably mounted in the multiple vertical sliding holes. The tops of the multiple vertical slide rods 14 are jointly fixedly mounted with a sealing baffle 15. The top of the sealing baffle 15 is in contact with the bottoms of the two inclined guide plates. The top of the fixed plate 13 and the bottom of the sealing baffle 15 are jointly fixedly mounted with multiple first springs 16. When adding materials, under the action of gravity, the materials will squeeze the sealing baffle 15 and move it downward to avoid it. After the materials are added, the elastic force of the first spring 16 will squeeze and push the sealing baffle 15 upward to automatically reset, thereby sealing the feed port 4, preventing dust from floating around, and being more environmentally friendly when used.

[0027] like Figure 4 As shown, a fixed protrusion 17 is fixedly installed on the top of the protective box 7, a sliding hole is provided on the side of the fixed protrusion 17, and a locking rod 18 is slidably installed in the sliding hole. A plurality of locking holes are evenly provided on the circumferential side of the adjusting knob 11, one end of the locking rod 18 extends into one of the locking holes, and an unlocking pull block 19 is fixedly installed on the other end of the locking rod 18. A reset baffle is fixedly sleeved on the locking rod 18, and the reset baffle is located between the fixed protrusion 17 and the adjusting knob 11. The reset baffle and the fixed protrusion 17 are fixedly installed with a second spring 20 on the sides close to each other. When the unlocking block 19 is pulled, the locking rod 18 will be driven to move out of the locking hole, and the adjusting knob 11 will be loosened. At this time, the falling direction of the material can be adjusted by turning the adjusting knob 11. When the unlocking block 19 is released, the reset baffle will be squeezed and pushed to automatically reset under the elastic force of the second spring 20, and the locking rod 18 will be automatically inserted into the locking hole, locking the adjusting knob 11 so that it cannot be rotated. This can effectively reduce the situation where the guide plate 6 rotates due to accidentally touching the adjusting knob 11 during use, and is stable and reliable when used.

[0028] like Figure 1 As shown, a plurality of transparent observation windows 21 are evenly fixed on the U-shaped mixing bin 1. Through the transparent observation windows 21, the staff can directly observe the internal situation of the U-shaped mixing bin 1.

[0029] Working principle: During use, when adding materials into the feed port 4, the materials will first fall onto the sealing baffle 15. At this time, under the action of gravity, the materials will squeeze the sealing baffle 15 to move downward to avoid it. When the material is added, under the elastic force of the first spring 16, the sealing baffle 15 will be squeezed and pushed to automatically reset upward, thereby sealing the feed port 4 to prevent dust from flying around. During this process, the staff can pull the unlocking block 19 to move the locking rod 18 out of the locking socket, loosen the adjusting knob 11, and then turn the adjusting knob 11. The rotation of the adjusting knob 11 will drive the control rod 8 and the worm 9 to rotate, and the rotation of the worm 9 will drive the worm gear 10 and its One of the horizontal rotating shafts 5 rotates synchronously, and the rotation of one of the horizontal rotating shafts 5 will drive the other horizontal rotating shaft 5 to rotate in the same direction or in the opposite direction at the same time through the two linkage gears 12, and then drive the two guide plates 6 to rotate in the same direction or in the opposite direction, so that the falling direction of the material can be adjusted until the material is evenly spread into the U-shaped mixing bin 1. Finally, the unlocking pull block 19 is directly released. Under the elastic force of the second spring 20, the reset baffle will be squeezed and pushed to automatically reset, and then the locking rod 18 can be driven to automatically insert into the locking hole, and the adjusting knob 11 will be locked all the time to avoid the guide plate 6 from rotating due to accidentally touching the adjusting knob 11 during use.
