Description

Technical Field

[0001] The invention relates to the technical field of explosive device production, in particular to a double-station charge weighing device which combines the advantages of constant volume weighing and quantitative weighing. Background Art

[0002] In the field of pyrotechnic production, charge weighing technology is one of the key technologies to achieve safe and automated production of pyrotechnics. It can be basically divided into two categories: quantitative weighing technology and constant volume weighing technology. Quantitative weighing technology is to achieve high-precision weighing control of the agent by real-time feedback control of the feed amount by the weighing sensor during the agent feeding process. However, its shortcomings are also obvious, with high cost, low efficiency, and certain control technology barriers. On the other hand, constant volume weighing technology has a simple structure, low cost, low control difficulty, and high efficiency, but poor accuracy and inability to achieve data traceability. It cannot meet high-precision weighing requirements in the field of pyrotechnic production.

[0003] The traditional method of using a metering plate to weigh medicine usually uses two methods to deal with excess medicine. One is to directly take away the medicine and the metering plate together, and the other is to first turn over and pour out the medicine in the metering plate hopper. Both methods are dangerous in handling and have certain requirements on the installation space of the mechanism, which is not conducive to safe production.

[0004] In addition, when the traditional double-station weighing unit is used to weigh medicines, two feeding devices are basically used to correspond to two weighing modules, which is costly, occupies a large space, and is not conducive to manual cleaning of the weighing environment.

The dislocation unloading method is adopted. After the residual material is cleaned out, the feeding mechanism is removed. It occupies a small space, has a simple structure, and is easy to clean.

[0048] Furthermore, it also includes a kick-out plate 9 and a fifth cylinder M5. The fifth cylinder M5 is connected to the frame 1 and then connected to the kick-out plate 9.

[0049] The detailed structure and usage of the device provided by this application are introduced in detail below.

[0050] The entire medicine weighing device mainly includes a frame 1, a metering unit 2, a leakage unit 3, a weighing unit 4, a dispensing unit 5, etc. Its ultimate 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 by a clamp 14. The lower end of the mounting plate 11 is fixedly connected to the guide rail 12, and can slide on the roller of the guide rail 12 installed on the frame 1, so that the hopper 21 of the metering device is moved to a position convenient for manual operation, reducing the operator's operating intensity, and can be fixed with screws at the plunger. Unqualified medicine box 53, when the medicine is unqualified in weighing, the medicine can be poured into it.

[0051] The metering device provided in the embodiment of the present application adopts a dual metering plate structure, and the first cylinder M1 and the second cylinder M2 respectively control two metering plates. The first metering plate 22 is a normal aperture metering plate, and the second metering plate 23 is a small aperture tonic metering plate.

[0052] The medicine in the hopper 21 will flow into the first metering hole through the first discharge port, and at the same time flow into the second metering hole through the second discharge hole. The first metering hole can accommodate normally measured medicine, and the amount of medicine placed in the second metering hole is less than the amount of medicine in the first metering hole.

[0053] When adding medicine begins, the funnel is located at position N (the first leakage position). After the first cylinder M1 pulls the first metering plate 22, the position of the first metering hole moves and is opposite to the discharge channel, so that the medicine mouth in the first metering hole flows into the funnel 31, and finally flows into the weighing cup 41 under the guidance of the funnel 31. The weighing cup 41 is installed on the weighing unit 4. The weighing unit 4 can weigh the medicine in the symmetrical medicine cup 41 in real time. After the weighing is qualified, the weighing cup 41 can be rotated under the action of the rotating cylinder M6 to pour the medicine into the dispensing unit 5.

[0054] The material dispensing unit 5 is equipped with two material receiving boxes, a first material receiving box 51 and a second material receiving box 52. When the material dispensing cylinder M7 is in the retracted state, the first material receiving box 51 is at position A (first unloading position), and the second unloading box is at position B (receiving position). At this time, the switch valve 7 on the first material receiving box 51 is retracted backwards under the action of the left inclined block 8, thereby opening the first material receiving box 51 (the first material receiving box 51 has received the medicine with the target weight when it is in the 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 in position B is in the extended state under the action of the reset spring 71. At this time, the switch valve 7 of the second material receiving box 52 is in the closed state, so that the medicine in the weighing cup 41 can be received.

[0055] Similarly, when the material dispensing cylinder M7 is in the extended state, the second material receiving box 52 moves to position C (the second unloading position), and the switch valve 7 of the second material receiving box 52 opens the valve under the action of the right inclined block 8, and pours the medicine into the product X2. The switch valve 7 of the first material receiving box 51 in position B is in the extended state under the action of the return spring 71. At this time, the switch valve 7 of the first material receiving box 51 is in the closed state, and the medicine from the weighing medicine cup 41 can be received. Through the two material receiving boxes, the workstations can receive and discharge materials at the same time, thereby improving the production efficiency of the device.

[0056] When the medicine weighing fails, if the medicine amount is lower than the target value, the second cylinder M2 retracts, the second metering hole moves and is opposite to the feeding channel, so that the medicine mouth in the second metering hole flows into the funnel 31, and finally flows into the weighing cup 41 under the guidance of the funnel 31, replenishing the medicine in the weighing cup 41 to reach the target value. Since the aperture of the second metering hole is small, the amount of medicine contained is also relatively small, so accurate addition can be achieved.

[0057] If it is higher than the target value, the fifth cylinder M5 extends forward, the kicking plate 9 extends, and hits the switch valve 7, so that the switch valve 7 on the receiving box at this position shrinks backward, opens the valve, and the medicine flows into the unqualified medicine box 53. The use of the dividing unit 5 and the inclined blocks 8 on both sides realizes the left and right double-station charging of the medicine, and improves 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 hole 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, and the residual material cleaning process requires small movements. The residual medicine can be cleaned to a safe area, and the metering device can be quickly taken out for cleaning. The device occupies a small space, has a simple structure, and is easy to clean, which is convenient for controlling floating medicine during the production process and cleaning floating medicine after production.

[0060] It combines the advantages of fixed volume charging and quantitative charging, uses a double metering plate feeding mechanism and a weighing module to achieve precision control of the feeding process and improve the pass rate. It uses two symmetrical medicine cups, so that materials can be received and weighed at any position, reducing the action of resetting the material cups, saving production time, and ensuring the consistency of the product charging amount by weighing each batch.

[0061] The dual-station material distribution system adopted realizes the use of one medicine weighing device and weighing sensor to complete the medicine filling of two stations without affecting the work efficiency and realizes the traceability of each batch of medicine, saving manufacturing costs.

[0062] The metering unit 2 is mounted on the guide rail 12 and can move on the guide rail 12, which is convenient for manual operation, reduces the operator's operating intensity, improves the visual range during operation, reduces the risk of blind operation, and improves the operator's operating safety.

[0063] In summary, the double-station charging device provided in the present application adopts a staggered unloading method, and its mechanism occupies little space, has a simple structure, and is easy to clean. Combining the advantages of fixed-volume charging and quantitative charging, the double-metering plate feeding mechanism and the weighing module are used to achieve precision control of the feeding process and improve the qualified rate. The hopper used is a symmetrical medicine cup. No matter which position, the material can be received and weighed, which reduces the action of resetting the material cup, saves production time, and ensures the consistency of the product charge by weighing each batch. The material distribution unit used, combined with the metering plate feeding device and the symmetrical hopper, realizes the efficient charging of "one-station weighing, two-station charging", reducing the manufacturing cost of the device. The functions of clearing excess materials, kicking waste, weighing, double-station charging, and sliding of the whole machine of the charging device are realized through a minimalist structural design.

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
