[0016] (III) Beneficial Effects

[0017] This invention provides a metering device with a function for separating products containing foreign matter. Compared with the prior art, it has the following advantages:

[0018] 1. This metering device with foreign matter separation function utilizes a swing separation mechanism. When the connecting rod falls, the semi-circular counterweight, which concentrates most of the center of gravity, is raised, increasing its potential energy. The connecting rod then returns to its original position. During the gentle pushing of the connecting rod, the material inside the foreign matter screening cylinder sways left and right. Qualified material penetrates through the filter screen and enters the material cylinder, while unqualified material is screened at the top of the filter screen. When all the raw materials inside the foreign matter screening cylinder have been screened into the material cylinder, simply rotate the device again to remove it from the material cylinder. The material cylinder is then weighed using a weighing instrument to calculate the amount of material screened inside. After weighing, the sealing pin is pulled out from the vent, allowing air to enter the inlet and quickly equalize the air pressure inside the sealing port. This allows the material cylinder to be quickly removed from the top of the weighing instrument, avoiding manual screening and facilitating the rapid removal and weighing of foreign matter.

[0019] 2. This metering device with the function of separating foreign matter from products uses a sealing plug and a rubber spring fixedly installed at the bottom of the base plate inside the foreign matter screening cylinder. When the foreign matter screening cylinder shakes left and right, the rubber spring will collide with the material. During the collision, it will swing left and right, and during the swing, it will stir the material inside the foreign matter screening cylinder, so that the material can be quickly screened and separated.

[0020] 3. This metering device with foreign matter separation function uses a limiting mechanism. The spring generates a rebound force, causing the telescopic rod to retract into the interior of the flipping rod. At the same time, the bottom of the fixed rod is inserted into the installation port, creating a limiting force. This causes the bottom of the fixed rod to be inserted into the interior of the sealing plug, creating a downward pressure on the sealing plug. This results in the sealing plug being tightly locked inside the foreign matter screening cylinder. Simultaneously, the flipping rod flips downward, causing the anti-slip plate fixedly connected to the outer wall of the counterweight to contact the ground. Due to the anti-slip texture on the surface of the anti-slip plate, slippage is prevented. The large ground contact area of ​​the anti-slip plate also increases the pressure. The semi-circular counterweight cannot be shaken if accidentally touched. Attached Figure Description

[0031] The technical solutions in the embodiments of the present invention have been clearly and completely described. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-9This invention provides a technical solution: a metering device with a function for separating products mixed with foreign matter, comprising a connecting rod 6, a sleeve 3, the bottom of the connecting rod 6 being fixedly mounted with the sleeve 3, and the interior of the sleeve 3 and the connecting rod 6 including a swing separation mechanism; the swing separation mechanism including a semi-circular counterweight 4, a weighing instrument 13, a material cylinder 7, a foreign matter screening cylinder 8, a sealing plug 9, and a fixing rod 10; the bottom of the sleeve 3 being fixedly mounted with the semi-circular counterweight 4, the top of the connecting rod 6 being threadedly mounted with the weighing instrument 13, the top of the weighing instrument 13 adsorbing the material cylinder 7, the interior of the material cylinder 7 being threadedly mounted with the foreign matter screening cylinder 8, and the interior of the foreign matter screening cylinder 8 being snapped with the sealing plug 9; the interior of the material cylinder 7 including a fixing port 701 and a suction cup 702, the fixing port 701 being located inside the material cylinder 7, and the top of the suction cup 702 being fixedly connected to the interior of the fixing port 701; the bottom of the foreign matter screening cylinder 8 including a connecting plate 801 and a screw 802. The bottom of the connecting cylinder 803, filter screen 804, and foreign object screening cylinder 8 are attached to the connecting plate 801. The top of the connecting plate 801 is threadedly connected to the bottom of the foreign object screening cylinder 8 via a screw 802. The connecting cylinder 803 is fixedly installed at the bottom of the connecting plate 801. The filter screen 804 is fixedly installed at the connection between the connecting cylinder 803 and the connecting plate 801. The weighing instrument 13 includes a fitting port 131, a vent port 132, an air inlet 133, a bottom connecting rod 134, and a sealing pin 135. The bottom of the weighing instrument 13 is fixedly connected to the bottom connecting rod 134. The top of the weighing instrument 13 has a fitting port 131. The middle of the fitting port 131 has an air inlet 133. The side of the air inlet 133 has a vent port 132. The sealing pin 135 is snapped into the inside of the vent port 132. The connecting rod 6 has an internal opening 601. The inside of the internal opening 601 is threadedly connected to the outer wall of the bottom connecting rod 134.

[0033] In this embodiment, during operation, the bottom connecting rod 134 installed at the bottom of the weighing instrument 13 is threadedly connected to the internal opening 601 of the connecting rod 6. This allows the weighing instrument 13 to be fixedly installed on the top of the connecting rod 6. At that time, the suction cup 702 fixedly installed at the bottom of the material cylinder 7 and the fitting opening 131 of the weighing instrument 13 are pressed together, causing the suction cup 702 to expel the air inside and be fixed inside the fitting opening 131. After the above steps are completed, the connecting cylinder 803 fixedly installed at the bottom of the foreign matter screening cylinder 8 is threadedly installed inside the material cylinder 7. At this time, the material is fed in. The material is thrown into the material cylinder 7, and a sealing plug 9 is attached to the top of the material cylinder 7. Then, the outer wall of the connecting rod 6 is grasped and gently pushed to one side. During this pushing process, because the mass of the semi-circular counterweight 4 is greater than the mass connected to the top of the connecting rod 6, objects with lower potential energy are more stable, and the object will inevitably change towards a lower potential energy state. When the connecting rod 6 falls, the semi-circular counterweight 4, which concentrates most of the center of gravity, is lifted, causing an increase in potential energy. Therefore, the connecting rod 6 will return to its original position. Thus, by continuously and gently pushing the connecting rod 6, the material will... During the left-right shaking process inside the material screening cylinder 8, qualified materials will penetrate through the filter screen 804 and enter the material cylinder 7, while unqualified materials will be screened at the top of the filter screen 804. When it is seen that all the raw materials inside the foreign matter screening cylinder 8 have been screened into the material cylinder 7, simply rotate it again to remove the foreign matter screening cylinder 8 from the material cylinder 7. At that time, the material cylinder 7 will be weighed using the weighing instrument 13 to calculate the amount of material screened inside the material cylinder 7. After weighing, the sealing pin 135 will be removed from the vent 1. Pulling out the inside of 32 allows air to enter the inside of the air inlet 133 from the vent 132, causing the air pressure inside the sealing port 131 to quickly equalize. This allows the material cylinder 7 to be quickly removed from the top of the weighing instrument 13. By tilting, the material inside the material cylinder 7 can be transported to the processing position. When the filter screen 804 needs to be changed in diameter, simply remove the screw 802 from the bottom of the foreign matter screening cylinder 8, causing the limit to be removed. This allows the connecting cylinder 803 to be removed from the bottom to replace different filter screens 804, facilitating the subsequent screening of materials of different diameters.

[0034] Specifically, the sealing plug 9 includes a rubber spring 904, a fixing block 901, a mounting rod 902, a base plate 903, and rubber springs 904. Rubber springs 904 are provided at both ends of the sealing plug 9. The top of the sealing plug 9 is fitted and connected to the fixing block 901. The bottom of the fixing block 901 is threaded with the mounting rod 902. The bottom of the mounting rod 902 is fixedly installed with the base plate 903. Rubber springs 904 are fixedly installed on the bottom circumference of the base plate 903.

[0035] In this embodiment, when the sealing plug 9 is installed inside the foreign matter screening cylinder 8, the mounting rod 902 is first sleeved inside the sealing plug 9, and then the fixing block 901 is threaded onto the top of the mounting rod 902. This limits the mounting rod 902 inside the sealing plug 9. At this time, the sealing plug 9 is snapped into the inside of the foreign matter screening cylinder 8, so that the base plate 903 is located inside the foreign matter screening cylinder 8. At the same time, the rubber spring 904 fixedly installed at the bottom of the base plate 903 is located inside the foreign matter screening cylinder 8. When the foreign matter screening cylinder 8 shakes left and right, the rubber spring 904 will collide with the material. During the collision, it will swing left and right. During the swing, it will stir the material inside the foreign matter screening cylinder 8, so that the material can be quickly screened and separated.

[0036] Specifically, the outer wall of the connecting rod 6 is fixedly sleeved with the connecting block 2, and a rotating mechanism is provided on both sides of the connecting block 2; the rotating mechanism includes a sleeve shaft 16, a shaft rod 14, and a flipping rod 5. The shaft rod 14 is fixedly installed on both sides of the connecting block 2, the outer wall of the shaft rod 14 is movably sleeved with the sleeve shaft 16, and the outer wall of the sleeve shaft 16 is fixedly installed with the flipping rod 5.

[0037] In this embodiment, during the rotation of the flipping rod 5, the sleeve shaft 16 fixedly connected to the outer wall will rotate on the outer wall of the shaft 14. During the rotation, the flipping rod 5 can flip itself, which facilitates its positioning and fixation.

[0038] Specifically, a limiting mechanism is sleeved inside the flipping rod 5; the limiting mechanism includes a pressing block 501, a telescopic rod 502, a spring 503, and a fixing rod 10. The pressing block 501 is movably sleeved inside the flipping rod 5, the telescopic rod 502 is fixedly installed on the top of the pressing block 501, the spring 503 is movably sleeved on the outer wall of the telescopic rod 502, and the fixing rod 10 is fixedly connected to one side of the top of the telescopic rod 502. The outer wall of the fixing rod 10 and the interior of the vent 132 are interlocked.

[0039] In this embodiment, a limiting mechanism is required. When the flipping rod 5 flips to be perpendicular and parallel to the foreign object screening cylinder 8 and the sealing plug 9, the telescopic rod 502 is pulled upward. During the pulling process, the squeezing block 501 moves upward along the inside of the flipping rod 5. When it moves to the top of the inner cavity of the flipping rod 5, the spring 503 movably sleeved on the outer wall of the telescopic rod 502 is squeezed. When the telescopic rod 502 extends out from the inside of the flipping rod 5, the bottom of the fixing rod 10 will be perpendicular and parallel to the mounting port 905. At this time, the telescopic rod 502 is released, causing the spring 503 to form a rebound force, which causes the telescopic rod 502 to retract into the inside of the flipping rod 5 by the rebound force. At the same time, the bottom of the fixing rod 10 is inserted into the inside of the mounting port 905, forming a limiting force, which causes the bottom of the fixing rod 10 to be inserted into the inside of the sealing plug 9, which will form a downward pressure on the sealing plug 9, so that the sealing plug 9 will be tightly locked into the inside of the foreign object screening cylinder 8, preventing the sealing plug 9 from falling off during shaking.

[0040] Specifically, a counterweight 11 is fixedly installed on the outer wall of the flipping rod 5, and an anti-slip plate 12 is fixedly installed on the outer wall of the counterweight 11. The outer wall of the anti-slip plate 12 has anti-slip texture.

[0041] In this embodiment, when the semi-circular counterweight 4 needs to be prevented from swaying left and right during operation, the flipping rod 5 is flipped downwards, causing the anti-slip plate 12 fixedly connected to the outer wall of the counterweight 11 to contact the ground. When in contact, because the surface of the anti-slip plate 12 is provided with anti-slip texture, the anti-slip plate 12 can be prevented from sliding. At the same time, the anti-slip plate 12 has a large ground contact area, and the pressure generated will also increase. The semi-circular counterweight 4 cannot be made to wobble when accidentally touched, thus facilitating subsequent weighing.
