Description

Technical Field

[0001] The present invention relates to the technical field of packaging machines, in particular to an intelligent device for quantitative packaging of solid materials. Background Art

[0002] The packaging of powder or granular materials such as ultrafine powder, metal ore and non-metallic ore powder, fine chemical raw materials, pharmaceutical chemical raw materials, dyes, pigments, calcium carbonate, kaolin, phenolic resin and even foods such as flour, food seasoning, etc. has generally changed from the previous manual packaging mode to the current semi-automatic and fully automatic mechanical packaging. Automatic quantitative packaging machines have the advantages of high packaging efficiency, accurate measurement, low manpower input and help to reduce the labor intensity of workers, so they are widely used by manufacturers of products not limited to the above mentioned products.

[0003] After searching, the Chinese patent number CN219750172U discloses a quantitative filling device for fertilizer production and packaging, including a storage bin, which is connected to a quantitative filling system through a feeding pipe, and the quantitative filling system includes a distribution bin, a volume quantitative part, a discharge mechanism and a filling part. The distribution bin is arranged on the machine base through a driving mechanism, the volume quantitative part is arranged below the distribution bin, the discharge mechanism is arranged below the volume quantitative part and corresponds to its position, and the filling part is arranged on the machine base and below the discharge mechanism. The utility model does not require workers to weigh and fill the materials, and adopts a mechanized method to control the quantitative filling of a measuring cup with a certain volume. It is simple and reliable, has a high degree of automation, and has high production efficiency. It is suitable for the technical field of fertilizer processing equipment.

[0004] The above-mentioned quantitative packaging equipment realizes the need of quantitative packaging through the cooperation of the discharge structure and the sealing structure. However, in actual use, when the material is about to reach the quantitative value, the closing of the sealing structure requires a certain amount of time to react, and the discharge structure is still working at this time, which will cause errors in the packaging quantity and may also cause material leakage. Based on this, the present invention designs an intelligent quantitative packaging device for solid materials to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent device for quantitative packaging of solid materials, which solves the problem of inaccurate packaging quantity in the background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] An intelligent device for quantitative packaging of solid materials, comprising:

[0008] A support frame, a material storage mechanism is installed on the top of the support frame and is used for storing materials;

[0009] A material distribution mechanism, which is installed at the bottom of the material storage mechanism and is used for quantitative packaging of materials. The material distribution mechanism includes a feeding component, a vibration component and a weighing component. The feeding component is located on the left side of the bottom of the material storage mechanism and is used for a large amount of material feeding. The vibration component is located on the right side of the bottom of the material storage mechanism and is used for accurate quantitative packaging of materials. The weighing component is located at the bottom of the feeding component and the vibration component and is used for weighing materials.

[0010] The packaging mechanism is located at the bottom of the material distribution mechanism and is used for packaging and sealing the materials.

[0011] Preferably, the material storage mechanism comprises a material storage tank installed on the top of the support frame, a sealing plate is installed at the bottom of the material storage tank and the sealing plate is of hollow design, and a climbing ladder is installed on one side of the support frame.

[0012] Preferably, the feed assembly includes a feed pipe installed on the left side of the bottom of the sealing plate, a feed box is installed at the bottom of the feed pipe, a through hole is opened on the side wall of the feed pipe, an insert plate is installed in the inner cavity of the through hole, and a shielding assembly is also installed on the back of the feed box.

[0013] The solid material is first stored in the storage tank on the top of the support frame. A sealing plate is provided at the bottom of the storage tank to maintain the sealing state. When the equipment is started, the material enters the feed box through the feed pipe of the feed assembly, and part of the material enters the vibration frame of the vibration assembly through the connecting pipe. The through hole and plug plate design on the side wall of the feed pipe allow flexible adjustment of the feed speed or temporary blocking of the material flow.

[0014] Preferably, the shielding assembly includes a mounting seat installed on the back side of the feed box, a first hydraulic telescopic rod is installed on one side of the mounting seat, a connecting rod is installed on one side of the first hydraulic telescopic rod, the outer ring of the connecting rod is fixedly connected to a fixing rod, the bottom of the fixing rod is fixedly connected to a shielding cover, a limit seat is installed in the inner cavity of the feed box, and the fixing rod is rotatably connected in the inner cavity of the limit seat.

[0015] The shielding component adjusts the shielding cover position to shield part of the feed inlet through the extension and contraction of the first hydraulic telescopic rod and the drive of the connecting rod, and finely controls the rate at which the material enters the vibration component to prepare for accurate quantitative measurement. When the total amount of material is close to the quantitative standard, the first hydraulic telescopic rod contracts, driving the shielding cover to completely shield the feed inlet, and inserts the plug plate to block the feed, achieving preliminary quantitative measurement.

[0016] Preferably, the vibration assembly includes a connecting pipe installed on the right side of the bottom of the sealing plate, the front and back sides of the connecting pipe are fixedly connected with connecting plates, a vibration rod is installed at the bottom of the connecting plate, a vibration seat is installed at the outer ring of the vibration rod, a vibration frame is fixedly connected between the vibration seats, a compression spring is installed at the bottom of the vibration seat, the compression spring is sleeved on the outer ring of the vibration rod and a shock absorber is installed at the bottom of the compression spring.

[0017] Preferably, the vibration assembly also includes a vibration baffle installed in the inner cavity of the feed box.

[0018] The vibration assembly starts, and the vibration system composed of the vibration rod, vibration seat and vibration frame generates high-frequency vibration, so that the material flows out evenly and slowly in the vibration frame. At the same time, the vibration baffle adjusts the material flow rate to achieve accurate quantitative measurement. During the vibration process, the compression spring and shock absorber play a buffering and stabilizing role to ensure a smooth and accurate vibration process.

[0019] Preferably, the weighing assembly includes a weighing box installed at the bottom of the feed box, a weighing tube is installed in the inner cavity of the weighing box, the front and back of the weighing tube are fixedly connected with electric push rods, a lifting rod is installed at the bottom of the electric push rod output rod, rotating rods are hinged on both sides of the lifting rod, and a weighing frame is hinged at the bottom of the rotating rod.

[0020] Preferably, a limit rod is installed at the bottom of the inner cavity of the weighing box, one side of the weighing frame is sleeved on the outer ring of the limit rod, and a pressure sensor is installed at the bottom of the weighing frame.

[0021] The material falls into the weighing frame, and the pressure sensor at the bottom monitors the material weight in real time and feeds back to the control system. When the material weight reaches the preset standard, the vibration component stops working, the electric push rod extends, drives the weighing frame to rotate to both sides, and discharges the weighed material into the packaging mechanism.

[0022] Preferably, the packaging mechanism is installed on a lower hopper at the bottom of the weighing box, a transport frame is installed at the bottom of the lower hopper, and a lowering pipe is installed at the bottom of the transport frame.

[0024] The material enters the packaging bag through the feeding hopper, transport frame and feeding tube. When the packaging mechanism is working, the second hydraulic telescopic rod extends, drives the bag clamping ring to move to the preset position and clamp the bag opening, completing the sealing of the bag or preparing for the subsequent sealing process. The inclination angle of the feeding tube can be adjusted to accommodate packaging bags of different sizes.

[0025] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0026] 1. The present invention realizes high-precision quantitative control of materials by introducing the coordinated work of the vibration component and the weighing component. The vibration component makes the material evenly distributed in the vibration frame and flows out slowly through high-frequency vibration. Combined with the real-time weight feedback of the weighing component, the material amount can be accurately adjusted to the preset value, which greatly improves the quantitative accuracy and reduces the problem of over-packaging caused by the continued falling of the material.

[0027] 2. The present invention is designed with multiple sealing and flexible control mechanisms. When the material is close to the quantitative standard, the shielding component responds quickly, and through the synergistic effect of the shielding cover and the plug plate, the material is blocked from further entering in time, avoiding material leakage caused by the delayed reaction of the sealing structure. At the same time, the bag clamping ring design in the packaging mechanism ensures the tight clamping of the packaging bag, further preventing material leakage during the packaging process.

[0028] 3. The present invention integrates a variety of automation components such as hydraulic telescopic rods, electric push rods, pressure sensors, etc., and realizes the full process automation control from material feeding, quantitative, weighing to packaging and sealing. Through the precise scheduling of each component by the intelligent control system, not only the production efficiency is improved, but also the complexity and error rate of manual operation are reduced, and the overall intelligent level of operation is improved.

[0048] The working principle of the embodiment of the present invention is: when the equipment is started, a part of the material enters the feed box 302 through the feed pipe 301 of the feed assembly 3, and the other part of the material enters the inner cavity of the vibration frame 405 through the connecting pipe 401.

[0050] The vibration assembly 4 further includes a vibration baffle 408 installed in the inner cavity of the feed box 302 .

[0051] The working principle of the embodiment of the present invention is: the contraction of the first hydraulic telescopic rod 702 drives the connecting rod 703 and the fixed rod 704 to rotate, so that the shielding cover 705 is located at the bottom of the feed box 302, and the plug plate 304 is inserted into the inner cavity of the through hole 303, so that no more materials are added to the feed box 302. Then the vibration component 4 is started, and the vibration system composed of the vibration rod 403, the vibration seat 404 and the vibration frame 405 generates high-frequency vibration, so that the material flows out from one side evenly and slowly in the vibration frame 405, and at the same time cooperates with the adjustment of the vibration baffle 408 to achieve accurate quantification of the material. During the vibration process, the compression spring 406 and the shock absorber 407 play a buffering and stabilizing role to ensure the smoothness and accuracy of the vibration process.

[0052] See also Figure 1-Figure 10 In the embodiment of the present invention, the weighing assembly 5 includes a weighing box 501 installed at the bottom of the feed box 302, a weighing tube 502 is installed in the inner cavity of the weighing box 501, the front and back sides of the weighing tube 502 are fixedly connected with electric push rods 503, a lifting rod 504 is installed at the bottom of the output rod of the electric push rod 503, and rotating rods 505 are hinged on both sides of the lifting rod 504, and a weighing frame 506 is hinged at the bottom of the rotating rod 505.

[0053] A limit rod 507 is installed at the bottom of the inner cavity of the weighing box 501 , one side of the weighing frame 506 is sleeved on the outer ring of the limit rod 507 , and a pressure sensor is installed at the bottom of the weighing frame 506 .

[0054] The packaging mechanism 6 is installed on a lower hopper 601 at the bottom of the weighing box 501 , a transport frame 602 is installed at the bottom of the lower hopper 601 , and a lowering pipe 603 is installed at the bottom of the transport frame 602 .

[0055] The packaging mechanism 6 also includes a second hydraulic telescopic rod 604 installed on the front and back of the lower hopper 601, a rotating seat 605 is installed at the bottom of the output rod of the second hydraulic telescopic rod 604, a rotating seat 606 is hinged on one side of the rotating seat 605, a rotating sleeve rod 607 is fixedly connected to one side of the rotating seat 606, a rotating inner rod 608 is fixedly connected to the inner cavity of the rotating sleeve rod 607, a hanging arm 609 is fixedly connected to the bottom of the rotating inner rod 608, a bag clamping ring 610 is installed at the bottom of the hanging arm 609, a clamping seat 611 is installed on the front and back of the transport frame 602, and the rotating inner rod 608 is rotatably connected in the inner cavity of the clamping seat 611.

[0056] The working principle of the embodiment of the present invention is as follows: the materials after quantitative adjustment by the vibration component 4 fall together into the weighing frame 506 of the weighing component 5. When the pressure sensor at the bottom of the weighing frame 506 determines that the materials inside the weighing frame 506 meet the material requirements, the vibration component 4 stops working. The electric push rod 503 extends, drives the lifting rod 504 to move downward, and the rotating rod 505 rotates the weighing frame 506 to both sides, so that the weighed materials enter the packaging mechanism 6 to complete the subsequent packaging process. The materials pass through the lower hopper 601, the transport frame 602 and the lower pipe 603 in turn and enter the packaging bag. When the logistics flow is completed, the packaging mechanism 6 starts working. The second hydraulic telescopic rod 604 extends, driving the rotating seat 605 to move downward, and the rotating seat 606, the rotating sleeve rod 607 and the rotating inner rod 608 rotate, so that the bag clamping ring 610 moves to a preset position and clamps the opening of the packaging bag, completing the sealing of the packaging bag or preparing for the subsequent sealing process to prevent subsequent excess materials from entering the packaging bag. The inclination angle of the discharge pipe 603 can be adjusted to adapt to packaging bags of different sizes.

[0057] Working principle: Solid materials are first stored in the storage tank 102 on the top of the support frame 101. A sealing plate 103 is provided at the bottom of the storage tank 102 to keep the materials in the tank sealed when the equipment is not working to prevent moisture or contamination. When the equipment is started, a part of the material enters the feed box 302 through the feed pipe 301 of the feed assembly 3, and the other part of the material enters the inner cavity of the vibration frame 405 through the connecting pipe 401. The through hole 303 and the plug plate 304 on the side wall of the feed pipe 301 are designed to allow the feed speed to be adjusted or the material flow to be temporarily blocked when necessary, so as to achieve flexible control. The back of the sealing plate 103 is also provided with a through hole 303 and a plug plate 304 to facilitate the overall flow control of the material.

[0058] After the material enters the feed box 302, it falls to the top of the weighing frame 506 due to gravity. Through the extension and retraction of the first hydraulic telescopic rod 702 and the driving of the connecting rod 703, the position of the shielding cover 705 can be adjusted to cover part of the feed inlet, and the rate of material entering the vibration component 4 can be further refined to prepare for accurate quantitative measurement. The pressure sensor at the bottom of the weighing frame 506 detects the weight of the material in real time and transmits the data to the control system.

[0059] When the total amount of material is close to the quantitative standard, the contraction of the first hydraulic telescopic rod 702 drives the connecting rod 703 and the fixed rod 704 to rotate, so that the shielding cover 705 is located at the bottom of the feed box 302, and the plug plate 304 is inserted into the inner cavity of the through hole 303, so that no more material is added to the feed box 302. Then the vibration component 4 is started, and the vibration system composed of the vibration rod 403, the vibration seat 404 and the vibration frame 405 generates high-frequency vibration, so that the material flows out from one side evenly and slowly in the vibration frame 405, and at the same time cooperates with the adjustment of the vibration baffle 408 to achieve accurate quantitative measurement of the material. During the vibration process, the compression spring 406 and the shock absorber 407 play a buffering and stabilizing role to ensure the smoothness and accuracy of the vibration process.

[0060] The materials after quantitative adjustment by the vibration component 4 fall into the weighing frame 506 of the weighing component 5. When the pressure sensor at the bottom of the weighing frame 506 determines that the materials inside the weighing frame 506 meet the material requirements, the vibration component 4 stops working. The electric push rod 503 extends, drives the lifting rod 504 to move downward, and the rotating rod 505 rotates the weighing frame 506 to both sides, so that the weighed materials enter the packaging mechanism 6 to complete the subsequent packaging process.

[0061] The materials pass through the lower hopper 601, the transport frame 602 and the lower feed pipe 603 in sequence and enter the packaging bag. When the flow of the logistics ends, the packaging mechanism 6 starts to work. The second hydraulic telescopic rod 604 extends, driving the rotating seat 605 to move downward, and the rotating seat 606, the rotating sleeve rod 607 and the rotating inner rod 608 rotate, so that the bag clamping ring 610 moves to the preset position and clamps the opening of the packaging bag, completing the sealing of the packaging bag or preparing for the subsequent sealing process to prevent subsequent excess materials from entering the packaging bag. The inclination angle of the lower feed pipe 603 can be adjusted to adapt to packaging bags of different sizes.

[0062] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit thereof, and the scope of the present invention is defined by the appended claims and their equivalents.
