Description

Technical Field

[0001] The invention relates to the technical field of mixed ingredients, in particular to a particle weighing, discharging and mixing device. Background Art

[0002] Weighing and discharging equipment has been applied to many industries. For example, in the food processing industry, there are many mixed-packaged foods, that is, different types of food are balanced in a certain quantity or weight, and then packaged together for sale. In the breeding industry, feed can be mixed and fed. In the fertilizer irrigation industry, fertilizer particles of different types and effects can be accurately allocated and irrigated according to the different growth conditions of plants, so that the growth of crops can be efficiently fertilized. For weighing these different types of particles, the manual operation process is cumbersome, inefficient, and the accuracy is not guaranteed. Therefore, a weighing and discharging device that can be applied to different particles is needed.

[0003] Among the existing mixed weighing equipment, for example, Chinese patent publication number CN214040277U published on 2021 / 08 / 24 discloses a mixed weighing equipment, which records a mixed loading equipment that sets a box body for loading materials under multiple hoppers, and measures the weight of the materials through a pressure sensor at the bottom of the box body, thereby accurately controlling the ratio of at least two materials. However, the problem with this prior art is that the conventional feeding funnel does not have a self-locking function, or the self-locking door of the feeding funnel is prone to malfunction under the long-term pressure of the material, resulting in material leakage. Chinese patent publication number CN113548204A, published on October 26, 2021, discloses an automatic weighing device, which adopts a solution that can solve the problem of leakage from conventional funnels to a certain extent. Specifically, the product enters the discharge track from the feed port and accumulates in the storage section of the discharge track. After the mass to be packaged is input on the control box, the linear vibrator works to send the products accumulated in the storage section of the discharge track into the discharge section. The material slides into the weighing table in the inclined discharge section. When the mass reaches the set value, the linear vibrator stops working and completes an automatic weighing. However, the weighing equipment still has the following problems: 1. After each weighing is completed and the vibration stops, the material may be retained in the discharge track or the discharge channel. After the equipment has been used for a period of time, the inclination angle of the discharge section becomes larger, and the material is easy to exceed the preset weight. 2. After a single weighing is completed, the material in the weighing container needs to be removed. Generally, the material needs to be manually removed from the weighing table and collected and sorted, which may cause material leakage and is inconvenient.

[0004] In addition, the prior art generally adopts the same weighing and unloading structure for different types of materials, which usually leads to the inability to accurately measure or unload certain materials. For example, for mixed materials of large particles and small particles, large particle materials are generally not easy to accurately control the weight due to their large volume (because the increase of one particle may cause a lack or excess of weight), and small particle materials are generally not easy to completely unload because the particles are small and easily remain in the weighing container, which also leads to inaccurate weight. Summary of the invention

[0005] The object of the present invention is to provide a particle weighing, discharging and mixing device, which can automatically weigh and discharge materials with little material omission and can accurately control the weight of each mixed material;

[0010] Furthermore, the movable material box includes a bottom-opening box body, the bottom surface of which is open and the bottom surface is in contact with a bottom plate, and a weighing sensor is provided at the bottom of the bottom plate; the pushing mechanism is used to make the bottom-opening box body move laterally away from or return to above the bottom plate.

[0011] Furthermore, a lifting and blocking mechanism for vertically closing or opening the outlet of the second funnel is provided in the second funnel.

[0012] Furthermore, the lifting and sealing mechanism includes a lifting rod arranged in the second funnel, and a plug is connected to the bottom of the lifting rod. The outer diameter of the plug matches the inner diameter of the outlet of the second funnel. The plug is controlled to be embedded in or detached from the second funnel to open it, and the upper and lower ends of the plug are conical surfaces respectively.

[0013] Furthermore, the overturning weighing and unloading device and the moving weighing and unloading device are respectively located above different positions of the material guiding trough along the material guiding direction.

[0014] Furthermore, the position of the first funnel and / or the overturning weighing and unloading device is adjustable, and the position of the second funnel and / or the moving weighing and unloading device is adjustable.

[0015] Furthermore, the material guide troughs include a plurality of juxtaposed material guides; the flipping weighing and unloading device and / or the movable weighing and unloading device can move between the plurality of the material guide troughs; or, the flipping weighing and unloading device and the movable weighing and unloading device are respectively provided above each of the material guide troughs.

[0016] The beneficial effects of the technical solution of the present invention are:

[0017] (1) By weighing and unloading small particles through the flipping unloading device, the small particles on the flipping slope can be completely dumped into the guide trough below by gravity, realizing fully automatic unloading of small particles and reducing labor costs.

[0044] Example 1

[0045] like Figure 1-Figure 8As shown, the present invention provides a particle weighing, discharging and mixing device, comprising: a mounting frame 1, in which a material guide trough 2 inclined in the up-down direction is provided; a flip weighing and unloading device, fixed on the mounting frame 1, comprising a flip material box 3 for weighing the weight of the material, and a flip mechanism 4 for flipping the material box to dump the material downward into the material guide trough 2, and a first funnel 5 is provided above the flip material box 3; a moving weighing and unloading device, fixed on the mounting frame 1, comprising a moving material box 7 for weighing the weight of the material, and a pushing mechanism 8 for moving the material box to push the material into the material guide trough 2, and a second funnel 9 is provided above the moving material box 7; the outlets of the first funnel 5 and the second funnel 9 are respectively provided with blocking mechanisms.

[0046] Specifically, the mounting frame 1 is an aluminum profile frame structure composed of a plurality of rods or profiles, and is used as the mounting base of the entire device. The guide trough 2 is fixed in the mounting frame 1, and is in an inclined posture with one end high and the other end low. After the material falls into the guide trough 2, it flows from the higher side of the guide trough 2 to the lower side. A collecting container is set at the lower end to collect the mixed material. The overturning unloading device is used for weighing and unloading small-particle materials, and the moving weighing and unloading device is used for weighing and unloading large-particle materials. Generally, the overturning unloading device is located above the upstream side of the guide trough 2, and the moving weighing and unloading device is located above the downstream side of the guide trough 2, that is, the small-particle materials in the guide trough 2 fall on the upstream side of the large-particle materials, so as to avoid the large drop of small-particle materials causing powder to be lifted. The flipping unloading device mainly unloads by flipping and dumping. The first funnel 5 injects material into the flipping material box 3. When the weighing sensor 11 at the bottom of the flipping material box 3 measures that the material weight reaches a preset value, a signal is sent to the blocking mechanism controlling the first funnel 5 to stop the injection. Then the flipping mechanism 4 drives the flipping material box 3 to flip and pour the material into the material guide trough 2 below. In this process, since the bottom surface of the flipping material box 3 is an inclined surface or a vertical surface after flipping, the small / light particle materials that are usually easily missed can fall completely into the material guide trough 2 under the action of gravity, thereby ensuring the completeness and integrity of the light particle discharge.

[0047] Similarly, the mobile weighing unloading device mainly unloads in a translational pushing manner. The second funnel 9 injects material into the mobile material box 7. When the weighing sensor 11 at the bottom of the mobile material box 7 measures that the material weight reaches a preset value, a signal is sent to the blocking mechanism controlling the second funnel 9 to stop the injection. The mobile material box 7 is then driven by the pushing mechanism 8 to translate. The bottom plate 702 of the mobile material box 7 is separated from the surrounding side walls. When the surrounding side walls move, a bottom outlet is formed between the stationary bottom plate 702. The material falls from the outlet into the material guide trough 2 below as pushed by the surrounding side walls. In this process, since the height distance between the mobile material box 7 and the bottom plate 702 is small, large particles with larger particle sizes will not be missed and can fall completely into the material guide trough 2, thereby ensuring the completeness and integrity of the discharge. In addition, as the material continues to fall from the bottom outlet, the value of the weighing sensor 11 at the bottom of the bottom plate 702 also changes continuously. Through this change, the weight of the material falling into the material guide trough 2 can be detected, so that the movement of the moving material box 7 is stopped at the appropriate time, and the material stops falling, thus realizing the secondary control of the weight ratio of the mixed material.

[0048] In addition, the flip scale unloading device can also adopt other structures, such as hydraulically pushing the flip material box 3 to flip in a similar way to the truck bed flipping method; the mobile scale unloading device can also adopt other structures, such as opening a certain side of the mobile material box 7, and providing a push plate inside the mobile material box 7. When the weight of the material reaches a preset value, the push plate is opened to push the material out of the open surface and fall into the material guide trough 2.

[0049] Example 2

[0050] This embodiment 2 specifically describes a flip scale unloading device and a first funnel 5 blocking mechanism that can be used in this device.

[0051] like Figure 1-Figure 5 As shown, the flip material box 3 includes a side-opening box body 301, a weighing sensor 11 is provided at the bottom of the side-opening box body 301, one side of the side-opening box body 301 is open, and the open side is in contact with and closed by a side plate 302; the flip mechanism 4 is used to hinge the side-opening box body 301 and the side plate 302 at a corner of the top, and control the side-opening box body 301 and the bottom of the side plate 302 to move away from or close to each other. An opening and closing blocking mechanism 6 is provided at the bottom outlet of the first funnel 5 to parallel close or open the outlet of the first funnel 5. The opening and closing blocking mechanism 6 includes two gear rods 601, one end of the two gear rods 601 is a gear structure that meshes with each other and is connected to a driving device, and the other end of the two gear rods 601 is provided with two opening and closing rods 602, and the opening and closing rods 602 are located at the bottom of the outlet of the first funnel 5 in an expanded structure, and the expanded structure of the two opening and closing rods 602 is controlled to move close to or away from the opening of the first funnel 5.

[0052] Specifically, the bottom of the side opening box body 301 is fastened with a weighing sensor 11 assembly, the center of which is installed with a central gear 401, and the side plate 302 is provided with an incomplete gear part that meshes with the gear part of the side opening box body 301. A bearing is installed in the center of the gear part of the side plate 302, and is installed in the installation frame 1 through the shaft 17 and the bearing seat 18. The flip motor 12 is fixed in the installation frame 1, and the side opening box body 301 is fixed by one side of the central gear 401 and the flange coupling 16 on the flip motor 12, and the center hole on the other side is dug to install the bearing, and is installed on the installation frame 1 by inserting the suspension arm 13 into the bearing. When the particles fall onto the weighing sensor 11 and reach the preset value, the flip motor 12 drives the flange coupling 16 and the central gear 401 to rotate, and the gear-shaped side plate 302 flips upward at the same time, that is, the two flip in opposite directions in both directions. Under the rotation drive of the box body, combined with the gravity of the particles themselves, the particles can be poured into the guide trough 2 intactly. It should be specially noted that, since the box body structure is usually designed to be square, in order to avoid the side opening box body 301 and the side plate 302 from self-locking due to the rigid angle when the two rotate relative to each other, resulting in failure to flip successfully, two long strip grooves 402 are opened on both sides of the side plate 302. When rotating, the rigid angle positions of the two side walls of the side opening box body 301 will enter the two long strip grooves 402 of the side plate 302, which has an avoidance effect, so that the flipping can be completed smoothly.

[0053] The opening and closing blocking mechanism 6 drives the steering wheel (located at the bottom of the gear rod 601 and connected to the gear rod 601, not shown in the figure) through the steering engine 603, driving the two meshing gear rods 601 to rotate, realizing the opening or closing of the opening and closing rod 602, that is, realizing the opening and blocking of the bottom of the funnel, or the steering wheel of the steering engine 603 can also be driven by an automatically controllable motor, the main purpose of which is to realize the rotation and closing of the two gear rods 601. When one end of the two gear rods 601 meshes and rotates, the other end moves away or approaches relatively, so that the opening and closing rod 602 connected thereto moves away or approaches synchronously, and the opening and closing rod 602 corresponding to the semicircular ring-shaped enlarged structure at the bottom of the outlet of the first funnel 5 has a sufficiently large area. When the two opening and closing rods 602 are completely closed, they are merged into a complete ring, which can completely block the outlet of the funnel and achieve good airtightness. The gear rod 601 and the opening and closing rod 602 are made of plastic material, which is low in cost and easy to replace. For particles with smaller size and weight, there is no need to bear too much weight. A simple gear claw opening and closing mechanism is adopted, which can operate quickly and has good sealing and feeding effects.

[0054] Example 3

[0055] This embodiment 3 specifically describes a mobile weighing unloading device and a second funnel 9 blocking mechanism that can be used in this device.

[0056] like Figure 1-Figure 2 and Figure 6-Figure 8As shown, the mobile material box 7 includes a bottom-opening box body 701, the bottom surface of the bottom-opening box body 701 is open, and the bottom surface contacts and closes with a bottom plate 702, and a weighing sensor 11 is provided at the bottom of the bottom plate 702; the pushing mechanism 8 is used to make the bottom-opening box body 701 leave or return horizontally above the bottom plate 702. A lifting and blocking mechanism 10 for vertically closing or opening the outlet of the second funnel 9 is provided in the second funnel 9. The lifting and blocking mechanism 10 includes a lifting rod 1001 arranged in the second funnel 9, and a plug 1002 is connected to the bottom of the lifting rod 1001. The outer diameter of the plug 1002 matches the inner diameter of the outlet of the second funnel 9. The plug 1002 is embedded in the plug or separated from the opening of the second funnel 9 by controlling the plug 1002, and the upper and lower ends of the plug 1002 are respectively conical surfaces.

[0057] Specifically, one side of the bottom opening box body 701 is fixed to the rack 803, and the other side is fixed to the guide rail slider 802 on the linear guide rail 801. The linear guide rail 801 is fixed to the aluminum profile mounting frame 1 through the guide rail fixing plate 805. The bottom opening box body 701 is separated from the bottom plate 702, and the weighing sensor 11 assembly is located on the bottom plate 702. Therefore, it is more suitable for the movement of larger particles, so that large particles are not missed and can be easily and quickly pushed into the guide trough 2 to improve work efficiency. When the particles fall on the weighing sensor 11 assembly and reach the preset value, the mobile motor 14 drives the gear 804 to drive the rack 803 to translate, and one side of the bottom opening box body 701 is fixed to the rack 803, and the other side is fixed to the guide rail slider 802 on the linear guide rail 801, thereby driving the bottom opening box body 701 to move outward, and a bottom outlet is formed between the bottom plate 702 and the stationary bottom plate, and the material falls from the outlet into the guide trough 2 below as pushed by the surrounding side walls.

[0058] The second funnel 9 is clamped and locked with a clamp 901. Long shafts 17 are installed on both sides of the clamp 901 and are placed on the aluminum profile mounting frame 1 through bearing seats 18. A screw rod 1003 driven by a lifting motor 15 is provided on one side of the outside of the second funnel 9. A lifting slider 1004 is installed on the screw rod 1003, which is connected to another lifting slider 1004 through a slider connecting plate 1005. A lifting rod 1001 is inserted into the other lifting slider 1004, and a plug 1002 is installed at the bottom of the lifting rod 1001. The lifting rod 1001 is fixed to the lifting slider 1004 by fixing rings above and below the lifting slider 1004. A horizontal bearing seat 18 is installed on the top plate 101 of the mounting frame 1 for fixing the screw rod 1003, and a limit seat 1006 is installed for positioning and limiting the lifting rod 1001 to ensure that the lifting rod 1001 is located at the center of the funnel. Thus, the lifting motor 15 drives the screw rod 1003, driving the lifting slider 1004 and its lifting rod 1001 to move up and down, so as to realize the opening and blocking of the bottom of the funnel by the plug 1002. The plug 1002 has conical surfaces at both ends and a columnar shape in the middle that fits the outlet of the second funnel 9, so that when the columnar area in the middle of the plug 1002 leaves the bottom of the funnel, and the conical surfaces at both ends do not leave the bottom of the funnel, incomplete unloading is formed. According to the position change of the conical area and the unloading mode with different annular opening areas formed between the funnel port, when the largest end of the conical area enters the funnel port, it is the minimum flow unloading, and when the smallest end of the conical area enters the funnel port, it is the maximum flow unloading, thereby realizing further precise control of the material quantity. It can also achieve good sealing when sealing and uniform scattering when feeding. For particles with larger size and weight, the lifting rod 1001 and the plug 1002 are used to better bear the weight of the particles when sealing, and the materials can fall evenly in all directions when feeding. When the required weight is reached, the funnel mouth can be sealed in time, which reduces the possibility of damage to the device and avoids the omission of particles, thereby improving the efficiency and accuracy of feeding and weighing.

[0059] Example 4

[0060] This embodiment 4 specifically describes the arrangement of the material guide trough 2, the overturning weighing and unloading device and the moving weighing and unloading device.

[0061] like Figure 1-Figure 2 As shown, the flip weighing and unloading device and the moving weighing and unloading device are respectively located above different positions of the material guide trough 2 along the material guide direction. The position of the first funnel 5 and / or the flip weighing and unloading device is adjustable, and the position of the second funnel 9 and / or the moving weighing and unloading device is adjustable. The material guide trough 2 includes a plurality of materials arranged in parallel; the flip weighing and unloading device and / or the moving weighing and unloading device can be moved between the plurality of material guide troughs 2; or, a flip weighing and unloading device and a moving weighing and unloading device are respectively arranged above each material guide trough 2.

[0062] Specifically, in the material flow direction of the guide trough 2, the flip unloading device is located above the upstream side of the guide trough 2, and the moving scale unloading device is located above the downstream side of the guide trough 2, that is, the small particles in the guide trough 2 fall on the upstream side of the large particles, avoiding the large drop of the small particles causing the powder to be lifted. Of course, other arrangements can also be used, such as exchanging the positions of the two.

[0063] A plurality of guide troughs 2 are arranged side by side, the position of the first hopper 5 and / or the flip weighing and unloading device is adjustable, and the position of the second hopper 9 and / or the moving weighing and unloading device is adjustable. One implementation scheme is that each guide trough 2 is provided with a corresponding flip weighing and unloading device and a moving weighing and unloading device for unloading, so that a variety of different mixing operations can be carried out simultaneously to improve work efficiency.

[0064] Another embodiment is that a plurality of guide troughs 2 arranged side by side can receive the discharge of the same overturning weighing and unloading device or the mobile weighing and unloading device. For example, a overturning weighing and unloading device containing small particles and the first funnel 5 can be moved between two guide troughs 2 to unload respectively, and two different mobile weighing and unloading devices, one of which contains primary large particles and only discharges to one guide trough 2, and the other contains secondary large particles and only discharges to the other guide trough 2, can obtain small particles + primary large particles, small particles + secondary large particles. The advantage of this structure is that it improves the utilization rate of the equipment and makes the mixing method more diversified.

[0065] The use process of this device is:

[0066] After the system receives the configuration instructions from the user, it starts feeding and weighing according to the required amount of each type of granular material input by the user. When the heavier granular material is fed and weighed, the lifting motor 15 installed on the aluminum profile mounting frame 1 starts to operate, and drives the screw rod 1003 to rotate under the drive of the coupling 16, so that the slider on the screw rod 1003 and the lifting rod 1001 move downward at the same time, and finally the plug 1002 at the bottom end of the lifting rod 1001 moves downward for a distance, and the granular material in the second funnel 9 starts to fall downward into the bottom opening box body 701, and is weighed by the weighing sensor 11 assembly on the bottom plate 702. When the weighing sensor 11 component detects that the heavier particles have reached the expected weight, the plug 1002 returns to its original position to seal the particles in the funnel. At this time, the moving motor 14 operates to drive the flange coupling 16 and the gear 804 to rotate, so that the rack 803 meshing with the gear 804 begins to move outward, and the rack 803 is tightly fixed to the bottom opening box body 701. The other side of the bottom opening box body 701 is slidably connected to the linear guide rail 801, so that the entire bottom opening box body 701 moves outward, and a bottom opening is formed between the stationary bottom plate 702, pushing the heavier particles therein into the lower material guide trough 2. Finally, the weighing sensor 11 component detects that the weight is zero, that is, the particles have been completely removed, and the bottom opening box body 701 is returned to its original position.

[0067] At the same time, the lightweight particles are fed and weighed, and the servo 603 on the multifunctional bracket operates to drive the steering wheel to rotate, so that the two meshing gear rods 601 connected to the steering wheel rotate, and the other two opening and closing rods 602 that were originally in a closed state open to both sides, so that the lightweight particles in the funnel are fed to the flip material box 3 below and the weighing sensor 11 assembly. When the weighing sensor 11 assembly detects that the lightweight particles have reached the expected weight, the servo 603 drives the two gear rods 601 back to their positions, so that the opening and closing rods 602 are closed again. At this time, the installed flipping motor 12 starts to operate, driving the flange coupling 16 to rotate. Through the gear meshing structure in the figure, the side opening box body 301 and the side plate 302 are flipped, so that the side opening box body 301 is flipped downward and the side plate 302 is flipped upward. Under the action of gravity, the lightweight particles are poured into the guide trough 2 completely without leakage. Finally, the weighing sensor 11 assembly detects that the weight is zero, and the flipping motor 12 drives the side opening box body 301 and the side plate 302 back to their positions, completing a weighing.

[0068] When different granular materials fall into the guide trough 2, the user can collect and package the mixed materials at the bottom of the guide trough 2, or use machine packaging at the bottom of the guide trough 2 to achieve full automation, and carry out collaborative mixing and packaging of different types of granular materials, so as to realize the assembly line mixed configuration in this cycle. The rigid parts of the device are made of alloy or steel, and some plates are made of acrylic. Different feeding, weighing and discharging methods can be selected according to the size and weight of the granular materials, and they can be changed flexibly.
