[0002] In the field of initiating explosive production, charge weighing technology is one of the key technologies for realizing safe and automatic production of initiating explosives, and can be basically divided into two categories: constant-quantity weighing technology and constant-volume weighing technology. The constant-quantity weighing technology realizes high-precision weighing control of the charge by real-time feedback control of the feeding amount by a weighing sensor during charge feeding, and has obvious disadvantages, such as high cost, low efficiency, and certain control technical barriers. The constant-volume weighing technology has simple structure, low cost, low control difficulty, and high efficiency, but has poor precision and cannot realize data traceability, and thus cannot meet the high-precision weighing requirement in the field of initiating explosive production.
[0003] In the conventional charge weighing method using a metering plate, the residual charge is usually handled in two ways: one is to directly take away the charge together with the metering plate, and the other is to first turn over and pour out the charge in the metering plate hopper. Both of the two ways have certain danger in handling, and have certain requirements for the installation space of the mechanism, which is not conducive to safe production.
[0004] In addition, in the conventional charge weighing method using a double-station charge weighing unit, two feeding devices are basically used to correspond to two weighing modules, which has high cost and large space occupation, and is not conducive to the cleaning of the weighing environment by workers.

[0049] The detailed structure of the device provided in the present application and the use method are described in detail below.
[0050] The whole medicine weighing device mainly comprises a rack 1, a metering unit 2, a material leakage unit 3, a weighing unit 4, a material distribution unit, etc. The final function is to load the weighed medicine into product X1 and product X2. The metering unit 2 can be fixed on the mounting plate 11 through the clamp 14, and the lower end of the mounting plate 11 is fixedly connected with the guide rail 12 and can slide on the guide rail 12 roller mounted on the rack 1, so that the hopper 21 of the metering device is moved to a position convenient for manual operation, the operation strength of the operator is reduced, and the plunger can be fixed by using a screw. When the medicine weighing is unqualified, the medicine can be poured into the unqualified medicine box 53.
[0051] The metering device provided in the embodiments of the present application adopts a double metering plate structure, and the first cylinder M1 and the second cylinder M2 control two metering plates respectively. The first metering plate 22 is a normal aperture metering plate, and the second metering plate 23 is a small aperture medicine supplementing metering plate.
[0052] The medicine in the hopper 21 flows into the first metering hole through the first lower outlet, and flows into the second metering hole through the second lower outlet. The first metering hole can accommodate normally metered medicine, and the second metering hole accommodates medicine in an amount less than that of the first metering hole.
[0053] When the medicine adding starts, the funnel is located at position N (the first material leakage position), the first cylinder M1 pulls the first metering plate 22, the first metering hole position is moved and opposite to the material leakage channel, so that the medicine in the first metering hole flows into the funnel 31, and finally flows into the medicine weighing cup 41 under the guidance of the funnel 31. The medicine weighing cup 41 is mounted on the weighing unit 4, and the weighing unit 4 can weigh the medicine in the medicine weighing cup 41 in real time. After the weighing is qualified, the medicine weighing cup 41 can be rotated under the action of the rotating cylinder M6 to pour the medicine into the material distribution unit.
[0054] The material distribution unit is provided with two material receiving boxes, i.e., the first material receiving box 51 and the second material receiving box 52. When the material distribution cylinder M7 is in the retracted state, the first material receiving box 51 is at position A (the first unloading position), and the second material receiving box is at position B (the material receiving position). At this time, the switch valve 7 on the first material receiving box 51 is retracted under the action of the left inclined block 8, so as to open the first material receiving box 51 (the first material receiving box 51 has received the medicine with the target weight at the material receiving position), and the medicine in the first material receiving box 51 flows into the product X1. The switch valve 7 of the second material receiving box 52 at position B is in the extended state under the action of the reset spring 71, so that the door of the switch valve 7 of the second material receiving box 52 is in the closed state, and the medicine from the medicine weighing cup 41 can be received.
[0055] Similarly, when the dispensing cylinder M7 is extended, the second receiving box 52 moves to position C (the second discharge position). The on-off valve 7 of the second receiving box 52 opens under the action of the right-hand bevel block 8, pouring the medicine into the product X2. The on-off valve 7 of the first receiving box 51 in position B is extended by the return spring 71. At this point, the on-off valve 7 of the first receiving box 51 is closed, allowing it to receive the medicine from the weighing cup 41. The two receiving boxes allow simultaneous receiving and discharging of materials at various workstations, improving the production efficiency of the device.
[0056] If the medicine weighing fails, or the dosage falls below the target value, the second cylinder M2 retracts, and the second metering hole moves relative to the discharge channel, allowing the medicine in the second metering hole to flow into the funnel 31. Guided by the funnel 31, the medicine ultimately flows into the medicine weighing cup 41, replenishing the medicine in the medicine weighing cup 41 to reach the target value. Because the second metering hole has a small diameter, the amount of medicine it can accommodate is also relatively small, thus achieving precise addition.
[0057] If the pressure is higher than the target value, the fifth cylinder M5 extends forward, the waste kicking plate 9 extends, and strikes the switch valve 7, causing the switch valve 7 on the receiving box at that position to retract backward, opening the valve and allowing the medicine to flow into the unqualified medicine box 53. The use of the material distribution unit in conjunction with the inclined blocks 8 on both sides realizes the left and right dual-station charging of the medicine, thereby improving the charging efficiency.
[0058] When the production is completed and the remaining medicine needs to be cleaned, the third cylinder M3 first changes from the retracted state to the extended state, so that the funnel 31 moves from position N (the first leakage position) to P (the second leakage position), so that the discharge port of the funnel 31 is directly above the residual material box 6, and then the first cylinder M1 and the second cylinder M2 are in the extended state, and the fourth cylinder M4 is retracted, driving the hopper 21 to retract, so that the discharge port of the hopper 21 is in the X position, ensuring that the first discharge port and the second discharge port are opposite to the discharge channel in the vertical direction. At this time, the material will flow into the residual material box 6 under the action of gravity, thereby realizing the function of clearing the residual material.
[0059] It can be seen that the device provided in the embodiment of the present application adopts a staggered hole unloading method, which does not require a flipping device. The residual material cleaning process requires small movements and can clean the residual medicine to a safe area. At the same time, the metering device can be quickly taken out for cleaning. The device occupies a small space, has a simple structure, is easy to clean, and is convenient for controlling floating medicine during the production process and cleaning floating medicine after production.
[0060] The double-metering plate feeding mechanism and the weighing module are combined to realize precision control of the feeding process and improve the qualified rate, the two symmetrical medicine cups can be used to receive and weigh the medicine regardless of the position, the action of resetting the medicine cup is reduced, the production time is saved, and the consistency of the product loading amount is ensured through the weighing of each product.
[0061] The double-station feeding system is adopted to realize two-station loading of the medicine amount using one medicine weighing device and weighing sensor without affecting the work efficiency, realize the traceability of the medicine of each product, and save the manufacturing cost.
[0062] The metering unit 2 is installed on the guide rail 12 and can move on the guide rail 12, which facilitates manual operation, reduces the operation strength of the operator, improves the visual range during operation, reduces the risk of blind operation, and improves the operation safety of the operator.
[0063] In summary, the double-station medicine weighing and loading device provided in the application adopts the staggered discharging mode, has small occupied space, simple structure, and is easy to clean. The advantages of constant volume loading and quantitative loading are combined, the double-metering plate feeding mechanism and the weighing module are used to realize precision control of the feeding process and improve the qualified rate, the hopper is a symmetrical medicine cup, which can receive and weigh the medicine regardless of the position, the action of resetting the medicine cup is reduced, the production time is saved, and the consistency of the product loading amount is ensured through the weighing of each product. The feeding unit is combined with the metering plate feeding device and the symmetrical hopper to realize efficient medicine weighing and loading of “one-station weighing and two-station loading”, reduce the manufacturing cost of the device, and realize the functions of excess material, kicking waste, weighing, double-station loading, and sliding of the whole machine through the simple structure design of the medicine weighing and loading device.
