Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to an impeller feeder capable of quantitative conveying. Background Technology

[0002] Impeller feeders are a type of continuous conveying equipment widely used in industrial production. They are mainly used for the precise conveying and quantitative feeding of powdery, granular, and small lump materials. Their core structure consists of a drive unit, a sealed cavity, and a multi-bladed rotor. The impeller is driven to rotate by a motor, and the material is pushed from the inlet to the outlet through the sealed cavity between the blades, forming a stable and controllable quantitative material flow.

[0003] However, in actual use, the above-mentioned equipment is prone to static electricity during the transmission of powder or granular materials at high speed, which easily adheres to the blades, resulting in the actual conveying capacity per revolution being lower than the theoretical value and causing a decrease in the feed rate. In view of this, we propose a quantitative conveying impeller feeder. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative conveying impeller feeder to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative conveying impeller feeder, comprising a conveying box, a drive motor fixedly connected to the side wall of the conveying box, a rotating shaft fixedly connected to the output end of the drive motor, blades sleeved on the side wall of the rotating shaft, and a quantitative component provided on the side wall of the conveying box, the quantitative component comprising:

[0010] Preferably, the abutting block abuts against the inner wall of the rotating shaft, and the two ends of the elastic element abut against two sets of abutting blocks respectively, with the abutting blocks abutting against the inner wall of the rotating shaft.

[0011] Preferably, the end of the spring away from the limiting block is fixedly connected to the inner wall of the feeding box, the limiting block is engaged with the limiting groove, and the end of the limiting block away from the spring is provided with a rounded chamfer.

[0012] Preferably, the end face of the scraper is movably connected to the blade, and a limiting strip is fixedly connected to the outer wall of the conveying box. The limiting strip is slidably connected to the outer wall of the connecting rod, and the limitation of the limiting strip makes the connecting rod and the movable frame only able to move linearly.

[0013] Preferably, the inner wall of the movable frame is fixedly connected with teeth, which mesh with the half gear, and the outer wall of the rotating rod is fixedly connected with a pulley, which is connected to a belt drive.

[0015] Preferably, the inner wall of the feeding box is fixedly connected with a protrusion, and the protrusion is movably connected to the blade.

[0016] Compared with the prior art, this utility model provides a quantitative conveying impeller feeder, which has the following beneficial effects:

[0017] 1. This quantitative conveying impeller feeder, through the setting of the drive motor, the insertion of the limit block and the limit groove to form a rigid stop, completely eliminates the blade position drift caused by inertia or load changes, and ensures the repeatability of filling and emptying of the conveying cavity each time. For every 120 degrees of blade rotation, the shaft rotates once, and the scraper moves back and forth laterally once, so that the scraper scrapes the area between two adjacent blades once, scraping off the material remaining on the blades, and removing residual material in time, avoiding the reduction of volume or flow fluctuation caused by the accumulation of sticky material, ensuring a constant cavity volume between blades, and ensuring the stability of continuous production.

[0018] 2. This quantitative conveying impeller feeder, through the setting of protrusions, causes the blades to vibrate continuously as they pass through multiple protrusions, breaking the adhesion between the material and the blade surface, forcing the adhered powder particles to fall off, reducing the effective volume loss of the cavity, and avoiding cumulative errors caused by micro-accumulation of material.

[0027] like Figures 1-7 As shown, this utility model provides a technical solution: a quantitative conveying impeller feeder, including a conveying box 1, a drive motor 2 fixedly connected to the side wall of the conveying box 1, a rotating shaft fixedly connected to the output end of the drive motor 2, blades 3 sleeved on the side wall of the rotating shaft, and a quantitative component 4 provided on the side wall of the conveying box 1. The quantitative component 4 includes a limit groove 401, an abutment block 402, an elastic element 403, a spring 404, a limit block 405, a scraper 406, a connecting rod 407, a movable frame 408, a rotating rod 409, a half gear 410, a belt 411, a servo motor 412, and a rotating shaft 413.

[0028] In one embodiment of this utility model, a limiting groove 401 is formed on the end face of the blade 3, an abutment block 402 is inserted into the inner wall of the blade 3, an elastic member 403 is fixedly connected to the end face of the abutment block 402, the abutment block 402 abuts against the inner wall of the rotating shaft, and the two ends of the elastic member 403 abut against two sets of abutment blocks 402 respectively, and the abutment block 402 abuts against the inner wall of the rotating shaft.

[0029] The limiting block 405 is inserted into the inner wall of the feeding box 1. A spring 404 is fixedly connected to the end face of the limiting block 405. The end of the spring 404 away from the limiting block 405 is fixedly connected to the inner wall of the feeding box 1. The limiting block 405 is engaged with the limiting groove 401. The end of the limiting block 405 away from the spring 404 is provided with a rounded chamfer.

[0030] A connecting rod 407 is fixedly connected to the side wall of the scraper 406, and a movable frame 408 is fixedly connected to the side wall of the connecting rod 407. A rotating rod 409 is connected to the outer wall of the material conveying box 1, and a half gear 410 is fixedly connected to the side wall of the rotating rod 409. The end face of the scraper 406 is movably connected to the blade 3. A limit strip is fixedly connected to the outer wall of the material conveying box 1. The limit strip is slidably connected to the outer wall of the connecting rod 407. The limitation of the limit strip makes the connecting rod 407 and the movable frame 408 only able to move linearly. A tooth is fixedly connected to the inner wall of the movable frame 408. The tooth meshes with the half gear 410. A pulley is fixedly connected to the outer wall of the rotating rod 409. The pulley is connected to the belt 411 for transmission.

[0031] The output end of the servo motor 412 is fixedly connected to the rotating shaft 413. The servo motor 412 is fixedly connected to the outer wall of the material conveying box 1. The side wall of the rotating shaft 413 is fixedly connected to the pulley 2, which is connected to the belt 411 for transmission. The outer wall of the material conveying box 1 is fixedly connected to the control device 5. The speed and start / stop of the drive motor 2 and the servo motor 412 can be controlled by the control device 5.

[0032] The drive motor 2 drives the blade 3 to rotate 120 degrees, causing the limiting block 405 to engage with the limiting groove 401 under the elasticity of the spring 404. At this time, the material is fed through the top of the feeding box 1. The limiting block 405 prevents the blade 3 from rotating. The engagement of the limiting block 405 with the limiting groove 401 forms a rigid stop, completely eliminating the position drift of the blade 3 caused by inertia or load changes, and ensuring the repeatability of filling and emptying of the feeding cavity each time. When the limiting block 405 is inserted into the limiting groove 401, the radial constraint of the abutment block 402 on the rotating shaft can suppress the slight rebound, ensuring that the blade 3 is completely fixed at the 120-degree position and eliminating the slight offset caused by the gap.

[0033] The control device 5 controls the speed of the drive motor 2 and the servo motor 412 to be in a 1:3 ratio, so that for every 120 degrees that the blade 3 rotates, the rotating shaft 413 rotates once. The rotation of the rotating shaft 413 drives the rotating rod 409 and the half gear 410 to rotate through the transmission of the belt 411. Every time the half gear 410 rotates once, it drives the movable frame 408, the connecting rod 407 and the scraper 406 to move back and forth laterally once, so that the scraper 406 scrapes the adjacent areas of the two blades 3 once, scraping off the material remaining on the blades 3, and removing the residual material in time, avoiding the reduction of volume or flow fluctuation caused by the accumulation of sticky material, ensuring a constant cavity volume between the blades 3, and ensuring the stability of continuous production.

[0034] In addition, a protrusion 6 is fixedly connected to the inner wall of the conveying box 1. The protrusion 6 is movably connected to the blade 3. When the blade 3 passes the protrusion 6, the blade 3 is lifted by the inclined side of the protrusion 6. After passing the protrusion 6, the blade 3 returns to its original position. The blade 3 passes through multiple protrusions 6, causing the blade 3 to vibrate continuously, which breaks the adhesion between the material and the surface of the blade 3, forces the adhered powder particles to fall off, reduces the effective volume loss of the cavity, and avoids the cumulative error caused by the accumulation of a small amount of material.

[0035] In this utility model, during use, the drive motor 2 drives the blade 3 to rotate 120 degrees, and the limiting block 405 is inserted into the limiting groove 401. At this time, the material is fed through the top of the feeding box 1. The limiting block 405 prevents the blade 3 from rotating. The insertion of the limiting block 405 and the limiting groove 401 forms a rigid stop, eliminating the position drift of the blade 3 caused by inertia or load changes. The control device 5 controls the speed of the drive motor 2 and the servo motor 412 to be 1:3, so that for every 120 degrees that the blade 3 rotates, the rotating shaft 413 rotates once. The rotation of the rotating shaft 413 drives the rotating rod 409 and the half gear 410 to rotate through the transmission of the belt 411. Every time the half gear 410 rotates once, it drives the movable frame 408, the connecting rod 407 and the scraper 406 to move back and forth laterally for one round. This allows the scraper 406 to scrape the adjacent areas of the two blades 3 once, scraping off the material remaining on the blades 3, avoiding the reduction in volume or flow fluctuation caused by the accumulation of sticky material.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
