[0002] The particle metering and conveying device is a device capable of automatically conveying granular materials such as rice, nuts, fertilizers, and granular medicines. In order to ensure fairness for every consumer when purchasing packaged products, the granular products are generally metered and then packaged by a packaging machine to ensure consistency between the packaged products.

[0003] The existing particle metering and conveying device generally uses an internal rotating measuring cup to collect granular materials and removes excess particles by a scraper during rotation, and then falls at a specified position for conveying. However, the gaps between the particles are large if the surfaces of the particles are irregular, which will cause the measuring cup to be transported without being completely filled, thereby reducing the metering accuracy of the conveyed products. Therefore, it needs to be improved. SUMMARY

[0017] (III) Beneficial effects

[0018] The application provides a high-efficiency vertical particle metering and conveying device for packaging.

[0019] Beneficial effects:

[0020] 1. The outer gear is rotated to drive the lower pressing plate to move up and down reciprocally. The particles in the processing shell are contacted in the process of the lower pressing plate pressing.

[0021] 2. The mutual cooperation between the impact spring and the impact ring is used. When the outer gear is rotated, the recess on the bottom surface is intermittently contacted with the protrusion on the top surface of the impact ring. When the protrusion is separated from the recess, the impact spring is contracted to store energy, and when the protrusion is contacted with the recess, the impact spring is reset and impacted with the outer gear ring, so that the measuring cup placed in the inside of the outer gear ring generates a shock, the particles in the inside of the measuring cup are moved, the particles are more dense, the problem of large gap between the particles is reduced, and the metering precision of the conveyed particle products is improved.

[0022] 3. The outer gear ring is rotated to drive the limiting wheel to rotate, and the limiting wheel drives the impact ball to rotate. When the impact ball rotates to a certain speed, the connecting spring is stretched, and the processing shell is intermittently impacted at the same time, so that the processing shell generates a shock. At this time, the particles in the inside of the processing shell are moved under the action of the shock, the gap of the particles before entering the inside of the measuring cup is reduced, the particles are more dense when entering, and the metering precision of the conveyed particles is improved.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] like Figures 1-13 As shown, this embodiment of the invention provides a high-efficiency vertical granule metering and conveying device for packaging, including a mounting base 1; a connecting ring 5 is fixedly connected to the upper surface of the mounting base 1, and a granulation mechanism 2 is arranged above the connecting ring 5; a feed nozzle 6 is fixedly connected to one side of the lower end of the granulation mechanism 2; a circular hole is opened on the bottom surface of the mounting base 1; an adjustment mechanism 4 is arranged at the center of the bottom surface of the mounting base 1, and a base 3 is fixedly connected to the lower end of the adjustment mechanism 4.

[0040] In the above process, the particles are processed by the granulation mechanism 2 to reduce the gap between the particles. After the particle density is adjusted, the particles fall out through the round hole and are conveyed inside the granulation mechanism 2. If it is inconvenient for people of different heights to use, the height of the feed nozzle 6 and the round hole can be adjusted by the adjustment mechanism 4.

[0041] The fine particle mechanism 2 comprises a processing shell 201, a door frame 202, a moving door 203, a pressing plate 204, a connecting frame 205, a limiting strip 206, a connecting assembly 207, a driving assembly 208, a fixing box 209, a scraping plate 210, a sliding groove 211, a rotating rod 212, a limiting disc 213, a rotating wheel 214, a transmission belt 215, a driving wheel 216, a knocking assembly 217, a connecting block 218, an external gear 219, a blocking sleeve 220, a knocking ring 221 and a knocking spring 222; the external gear 219 is rotationally connected to the upper surface of the connecting ring 5; the upper surface of the external gear 219 is provided with a plurality of annular equiangularly and uniformly distributed circular grooves corresponding in diameter to the circular holes; the circular grooves are internally provided with the measuring cups 7; the blocking sleeve 220 is arranged outside the measuring cups 7 and is fixedly connected to the bottom surface of the external gear 219; the processing shell 201 is rotationally connected to the upper surface of the external gear 219; the feeding nozzle 6 is fixedly and communicatively connected to one side of the lower end of the processing shell 201; the connecting block 218 is arranged outside the external gear 219; the connecting block 218 is provided in plurality along the external gear 219 and is fixedly connected to the outer sides of the processing shell 201 and the connecting ring 5 at two ends thereof; the scraping plate 210 is fixedly connected to the inner side of the processing shell 201 and is in contact with the upper surface of the external gear 219; the fixing box 209 is fixedly connected to the upper surface of the processing shell 201; the limiting disc 213 is fixedly connected to the inner side of the fixing box 209; the rotating rod 212 is rotationally connected to the center of the top surface of the mounting seat 1 and sequentially penetrates the external gear 219, the scraping plate 210 and the limiting disc 213 at the upper end thereof; the rotating rod 212 is fixedly connected to the contact surface of the external gear 219; the mounting seat 1 is fixedly provided with a stepping motor at the periphery of the top surface thereof; the stepping motor is fixedly provided with a spur gear at the output end thereof and the spur gear is in mesh with the outer side of the external gear 219.

[0042] In the above, the mutual cooperation between the scraping plate 210 and the external gear 219 is provided, so that when the external gear 219 drives the measuring cup 7 to rotate, the scraping plate 210 scrapes the excess material above the measuring cup 7, so that the particle quantity in each measuring cup 7 tends to be consistent.

[0043] The lower pressing plates 204 are distributed on both sides of the scraping plate 210, and the bottom ends of the linkage frame 205 are fixedly connected to the upper surfaces of the two separated lower pressing plates 204; the limiting strips 206 are arranged above the lower pressing plates 204, and the inner sides of the limiting strips 206 are slidingly connected with cylinders; the lower ends of the cylinders are fixedly connected to the upper surfaces of the lower pressing plates 204; the rotating wheels 214 are fixedly connected to the upper ends of the rotating rods 212, the driving assemblies 208 are arranged outside the processing shell 201; the driving wheels 216 are arranged above the driving assemblies 208, and the rotating wheels 214 are drivingly connected with the driving wheels 216 through the transmission belts 215; the connecting assemblies 207 are arranged inside the fixed boxes 209; the sliding grooves 211 are arranged on both sides of the fixed boxes 209, and the two ends of the connecting assemblies 207 are slidingly connected with the inner sides of the sliding grooves 211; the connecting assemblies 207 are matched with the driving assemblies 208 and the lower pressing plates 204 respectively; the knocking assemblies 217 are arranged outside the processing shell 201, and the knocking assemblies 217 are matched with the upper surface of the mounting seat 1.

[0044] In the above, the lower pressing plates 204 are pressed downward, and contact the accumulated particles in the process of pressing, so that the particles are pressed more densely, and the problem of reducing the measurement accuracy of the particle product due to too many particle gaps is solved.

[0045] The impact ring 221 is arranged directly below the outer gear 219, and the outer side of the impact ring 221 is in contact with the inner side of the processing shell 201; the upper surface of the impact ring 221 is provided with a plurality of uniformly distributed protrusions; the bottom surface of the outer gear 219 is provided with grooves corresponding to the protrusions, and the grooves and the protrusions are matched with each other; the impact springs 222 are arranged below the impact ring 221, and the two ends of the impact springs 222 are fixedly connected with the lower surface of the impact ring 221 and the upper surface of the mounting seat 1 respectively; a through groove is arranged on one side of the processing shell 201, and a door frame 202 is fixedly connected to the outer side of the processing shell 201 close to the through groove; a moving door 203 is slidingly connected to the inner side of the door frame 202, and a handle is fixedly installed on the outer side of the moving door 203.

[0046] In the above, when the outer gear 219 rotates, the grooves at the bottom intermittently contact the protrusions in the impact ring 221, when the protrusions slide out of the grooves and separate, the impact springs 222 will store energy and contract, and when the grooves contact the protrusions, the impact ring 221 will be pushed to impact the outer gear 219, so that the outer gear 219 and the particles above produce a shock, so that the particles move relative to each other and reduce the gap size between the particles.

[0047] The connecting assembly 207 comprises a connecting plate 20701, a limiting rod 20702, a connecting rod 20703, a pushing spring 20704 and an upper pull ring 20705; the middle end of the connecting plate 20701 is sleeved outside the rotating rod 212; the two ends of the connecting plate 20701 are slidably connected with the inner side of the sliding groove 211; the limiting rod 20702 is slidably connected with the inner side of the two ends of the connecting plate 20701 close to the sliding groove 211; the two ends of the limiting rod 20702 pass through the connecting plate 20701 and are fixedly connected with the inner surface of the sliding groove 211; the lower end of the connecting rod 20703 is fixedly connected with the top surface of the pressing plate 204, and the upper end of the connecting rod 20703 passes through the connecting plate 20701 and extends upwards; the upper pull ring 20705 is fixedly sleeved outside the upper end of the connecting rod 20703; the pushing spring 20704 is sleeved outside the connecting rod 20703, and the two ends of the pushing spring 20704 are fixedly connected with the mutually close sides of the connecting plate 20701 and the pressing plate 204 respectively.

[0048] In the above, by setting the cooperation between the limiting rod 20702 and the connecting plate 20701, the connecting plate 20701 is limited, the left and right shaking of the connecting plate 20701 during movement is reduced, and the movement of the connecting plate 20701 is more stable.

[0049] The lower end of the connecting rod 20703 is fixedly connected with the top surface of the pressing plate 204, and the upper end of the connecting rod 20703 passes through the connecting plate 20701 and extends upwards; the upper pull ring 20705 is fixedly sleeved outside the upper end of the connecting rod 20703; the pushing spring 20704 is sleeved outside the connecting rod 20703, and the two ends of the pushing spring 20704 are fixedly connected with the mutually close sides of the connecting plate 20701 and the pressing plate 204 respectively.

[0050] In the above, by setting the pushing spring 20704, when the connecting plate 20701 pushes down the pressing plate 204 and contacts the particles through the pushing spring 20704, the pushing spring 20704 is contracted, the connecting plate 20701 can continue to move after being pressed, and the problem of the connecting plate 20701 being stuck is reduced.

[0051] The driving assembly 208 comprises a fixed frame 20801, a mounting frame 20802, a moving plate 20803, a limiting block 20804, a limiting groove 20805, a bevel gear plate 20806, a bevel gear 20807, a driving column 20808 and a rotating column 20809; the fixed frame 20801 is fixedly connected to one side of the processing shell 201; the mounting frame 20802 is fixedly connected to the outer surface of the middle end of the fixed frame 20801; the limiting groove 20805 is arranged on both sides of the fixed frame 20801, and the limiting block 20804 is slidingly connected to the inner side of the fixed frame 20801; the moving plate 20803 is slidingly connected to the inner side of the fixed frame 20801, and the two sides of the fixed frame 20801 are fixedly connected to one side of the limiting block 20804.

[0052] In the above, the cooperation between the limiting block 20804 and the limiting groove 20805 is arranged, so that the limiting block 20804 limits the moving plate 20803, preventing the moving plate 20803 from rotating when moving up and down, which causes the device to be unable to be used.

[0053] The bevel gear plate 20806 is rotatably connected to the side of the mounting frame 20802 close to the moving plate 20803; the side of the moving plate 20803 close to the bevel gear plate 20806 is provided with a rectangular groove, and the driving column 20808 is slidingly connected to the inner side of the rectangular groove; the end of the driving column 20808 away from the moving plate 20803 is fixedly connected to the surface of the bevel gear plate 20806; the bevel gear 20807 is engaged with the upper end of the bevel gear plate 20806; the rotating column 20809 is fixedly connected to the inner side of the bevel gear 20807; and the upper and lower ends of the rotating column 20809 are respectively fixedly connected to the inner side of the driving wheel 216 and rotatably connected to the upper surface of the fixed frame 20801.

[0054] In the above, the driving column 20808 rotates and moves around the center of the bevel gear plate 20806, so that the driving column 20808 pushes the moving plate 20803 to move up and down reciprocally, thereby extruding particles within a certain height range and making the particles more dense.

[0055] The knocking assembly 217 comprises a rotating rod 21701, a rotating gear 21702, a limiting wheel 21703, a hitting ball 21704 and a connecting spring 21705; the rotating rod 21701 is rotatably connected to the upper surface of the mounting seat 1; the rotating gear 21702 is fixedly sleeved on the outer side of the rotating rod 21701; the rotating gear 21702 is engagedly connected with the external gear 219; the limiting wheel 21703 is fixedly connected to the upper end of the rotating rod 21701; one end of the connecting spring 21705 is fixedly connected to the inner side of the limiting wheel 21703, and the connecting spring 21705 is arranged as a plurality of connecting springs and is uniformly distributed along the limiting wheel 21703 at equal angles; and the hitting ball 21704 is fixedly connected to the end of the connecting spring 21705 away from the limiting wheel 21703.

[0056] In the above, by setting the interaction between the connecting spring 21705 and the impact ball 21704, the elasticity of the connecting spring 21705 pushes the impact ball 21704 to impact, and at the same time, the connecting spring 21705 will cause the impact ball 21704 to move more violently.

[0057] The adjustment mechanism 4 includes an adjustment sleeve 401, an adjustment bar 402, a drive block 403, a threaded screw 404, and a rotating handle 405. The adjustment sleeve 401 is fixedly connected to the center of the upper surface of the base 3. The adjustment bar 402 is slidably connected inside the adjustment sleeve 401, and the upper end of the adjustment bar 402 is fixedly connected to the center of the bottom surface of the mounting base 1. A groove is provided on the side of the adjustment sleeve 401 away from the adjustment bar 402, and the drive block 403 is slidably connected to the inside of the groove. One side of the drive block 403 is fixedly connected to the lower end of the adjustment bar 402. The outer side of the threaded screw 404 is threadedly connected to the inner side of the drive block 403, and both ends of the threaded screw 404 are rotatably connected to the inner side of the groove. The upper end of the threaded screw 404 passes through the adjustment sleeve 401 and is fixedly connected to the rotating handle 405.

[0058] In the above, by setting the mutual cooperation between the threaded screw 404 and the drive block 403, the threaded screw 404 rotates to drive the adjusting bar 402 to move up and down, and limits the mounting base 1 when it stops.

[0059] Working principle: When in use, if the capacity of measuring cup 7 is inconsistent with the required capacity, first push the sliding door 203 and open the sliding door 203. Then start the stepper motor, so that the stepper motor drives the external gear 219 to rotate through the spur gear. When the external gear 219 rotates, it drives multiple inner measuring cups 7 to rotate and pass through the sliding door 203. At this time, the worker takes out the measuring cup 7 from the inside of the circular groove above the external gear 219 and replaces the measuring cup 7 with the required capacity and puts it back in. After the measuring cup 7 is replaced, the sliding door 203 is closed.

[0060] If the feed nozzle 6 is too high or too low and inconvenient to install and use, you can turn the handle 405 to rotate the threaded screw 404. The rotating threaded screw 404 will drive the adjusting bar 402 to slide up and down inside the adjusting sleeve 401 through the drive block 403, so that the feed nozzle 6 and the round hole are in the right position. Then, the round hole opened below the mounting base 1 is connected to the input port of the packaging machine through the hose.

[0061] Next, the feeding nozzle 6 is connected with the outlet of the pneumatic conveyor through the pipeline, and the pneumatic conveyor generates airflow through the air compressor to form a stable air pressure difference in the closed pipeline, so that the particulate material is blown into the inside of the processing shell 201 through the pipeline. The particulate material blown into the inside of the processing shell 201 will accumulate on the upper surface of the outer gear 219. When the particulate material accumulated on the surface of the outer gear 219 reaches a certain range, the stepping motor is started to drive the outer gear 219 to rotate through the gear. At this time, the outer gear 219 will drive the measuring cup 7 to move, and at the same time, the material accumulated above the outer gear 219 will also move. In the process of moving, the particulate material will contact the scraping plate 210, and the excess particulate above the measuring cup 7 will be pushed flat through the scraping plate 210, so that the particulate to be packaged in the inside of the measuring cup 7 tends to be consistent.

[0062] When the outer gear 219 rotates, the rotating rod 212 at the center position also rotates. The rotating rod 212 in the rotating state drives the rotating wheel 214 to rotate, and the rotating wheel 214 drives the driving wheel 216 to rotate through the transmission belt 215, and drives the bevel gear 20807 directly below the rotating column 20809 to rotate. Since the bevel gear 20807 is engaged with the bevel gear plate 20806, the driving column 20808 fixed on the surface is driven to rotate and move along the bevel gear plate 20806. When the driving column 20808 moves, it slides on the inside of the moving plate 20803 and pushes the moving plate 20803 to move up and down inside the fixed frame 20801. When the moving plate 20803 moves up and down, the connecting plate 20701 also moves up and down. When the connecting plate 20701 moves downward, it pushes the downward pressing plate 204 to move downward through the pushing spring 20704. When the downward pressing plate 204 moves downward, it will contact the particulate material. If the particulate material is accumulated above the measuring cup 7 at this time, the pushing spring 20704 will be forced to contract during the continuous downward pressing of the downward pressing plate 204, so that the downward pressing plate 204 can continue to press downward and push the material to the inside of the measuring cup 7 for slight extrusion, so that the material in the measuring cup 7 is more sufficient. When the downward pressing plate 204 above approaches the feeding nozzle 6, the connecting plate 20701 moves upward and contacts the upper pull ring 20705, so that the upper pull ring 20705 drives the downward pressing plate 204 to move upward through the connecting rod 20703 to reset the feeding nozzle 6 to continue to accumulate. In this way, the feeding nozzle 6 continues to accumulate.

[0063] At the same time, the outer gear 219 will be in intermittent contact with the protrusions above the impact ring 221 through the groove on the lower surface when rotating, and will drive the push impact ring 221 to move back and forth multiple times under the cooperation of the impact spring 222, impact the outer gear 219, make the measuring cup 7 placed in the circular groove of the outer gear 219 produce a shock, and through the shock and the downward extrusion of the lower pressing plate 204, the granular materials in the measuring cup 7 move relative to each other, the gap rate between the particles is reduced, and the material distribution is more sufficient.

[0064] Since the outer gear 219 is externally meshed with the rotating gear 21702, the outer gear 219 will drive the rotating rod 21701 to rotate through the rotating gear 21702, and when the rotating rod 21701 rotates, the limiting wheel 21703 at the upper end will also rotate, at this time the impact ball 21704 inside the limiting wheel 21703 will be thrown and will move in and out under the cooperation of the connecting spring 21705, so that the impact ball 21704 knocks the processing shell 201, produces a shock to the processing shell 201 and the particles inside, reduces the gap of the particles before entering the measuring cup 7, makes the particles more dense when entering, and improves the product measurement accuracy.

[0065] Before starting the packaging machine, when the outer gear 219 drives the measuring cup 7 to move to the circular hole on the surface of the mounting seat 1, the granular materials inside the measuring cup 7 will fall out of the inside of the measuring cup 7 through the circular hole, and the falling materials will enter the inside of the packaging machine through the hose, so that the started packaging machine packs the granular materials.

[0066] Example two:

[0067] The difference between this embodiment and example one is that the two rotating rods 21701 are located on both sides of the feeding nozzle 6, when the impact ball 21704 is in a rotating state and knocks the processing shell 201, the impact ball 21704 will also knock the outside of the feeding nozzle 6, so that the feeding nozzle 6 also produces a shock, reduces the problem of blockage of the granular materials inside the feeding nozzle 6, and at the same time, when multiple impact balls 21704 impact the processing shell 201, the shock will shake off the granular materials adhered to the inside of the processing shell 201, thereby reducing the problem of waste of granular materials caused by residual particles.

[0068] Example three:

[0069] The difference between this embodiment and example two is that the adjusting mechanism 4 that drives the mounting seat 1 to move up and down is replaced by a pneumatic cylinder, and the controller controls the extension end of the pneumatic cylinder to push the mounting seat 1 to move up and down, so as to adjust the height of the mounting seat 1 and the feeding nozzle 6 to be at a suitable position.
