Description

Technical Field

[0001] This utility model belongs to the field of metering device technology, specifically relating to an online metering device for material consumption in a silk-making workshop. Background Technology

[0002] In the silk-making workshop, there are multiple screening mechanisms for dust, smoke, and stems during the production process. The materials screened out by these mechanisms are directly recycled by a negative pressure pipeline system without a metering system. However, with the current emphasis on intelligent manufacturing, there is a lack of basic data for analyzing production consumption, efficiency, and management. Therefore, the comprehensive metering upgrade of the screening and recycling devices in the silk-making workshop is necessary to adapt to the needs of modern intelligent production management. The online material consumption metering device is mainly used for real-time monitoring and accurate calculation of material consumption in industrial production, which can improve resource utilization efficiency and optimize production management.

[0003] In the cigarette manufacturing workshop, the screened materials are discharged into an online metering device, where a dynamic belt scale is used to weigh them. The high-frequency friction between these materials and the screen, especially in dry environments, easily generates static electricity, causing lightweight materials such as tobacco shreds and stems to become charged. When the screened materials fall, this static charge can cause them to clump together or adhere to the metal inner walls of the device. Even if the inner walls of the device have an anti-static coating, long-term use can lead to aging and damage to the coating, affecting its conductivity. This results in less material falling onto the dynamic scale than the actual flow rate, leading to metering errors and making it impossible to obtain accurate data, directly impacting the effectiveness of data analysis.

[0004] Therefore, this utility model proposes an online metering device for material consumption in a silk-making workshop that releases the static electricity carried by the material during the feeding process before dynamic weighing, so as to facilitate data analysis. Utility Model Content

[0005] To address the problem in existing technologies that materials may carry static electricity before weighing and metering, causing them to adhere to the inner wall of the device and thus affecting data accuracy, this utility model provides an online material consumption metering device for a silk-making workshop.

[0006] The present invention adopts the following technical solution: an online metering device for material consumption in a silk-making workshop, comprising a frame and a belt scale installed inside the frame, wherein the belt scale is provided with a feeding hopper at the top and a connecting pipe fixedly connected to the bottom of the feeding hopper, and a conductive component is provided inside the connecting pipe;

[0007] The conductive component is grounded so that static electricity can be released when the material comes into contact with it. It includes a set of staggered inclined conductive plates and through slots opened on the conductive plates. The material falling onto the conductive component slows down its falling speed as it passes through the conductive plates. At the same time, the buffer strip fixedly connected to the conductive plates ensures that the material makes contact with the conductive component as much as possible.

[0008] Preferably, the top of the feed hopper is provided with a timed discharge mechanism, which is fixedly connected to the screening machine, and its discharge port is matched with the feed hopper.

[0009] Preferably, a guide plate is provided at the bottom of the forward direction end of the belt scale, the guide plate is fixedly connected to the frame, and a display screen is installed on one side of the top of the frame.

[0010] Preferably, the guide plate is inclined downwards.

[0011] Preferably, a receiving hopper is provided at the lower end of the guide plate, and the lower end of the guide plate extends into the receiving hopper.

[0012] Preferably, a negative pressure pipe is fixedly connected to the bottom of the receiving hopper, the receiving hopper is connected to the negative pressure pipe, one end of the negative pressure pipe is connected to a negative pressure fan, and a support component is installed outside the negative pressure pipe to contact the ground.

[0013] Preferably, the buffer strips on the conductive plate are a set, and the height of the buffer strips gradually increases from the downward tilt direction of the conductive plate.

[0014] Preferably, a set of the conductive plates is inclined in a Z-shape, with the through groove located at the lower end of the conductive plate.

[0015] Beneficial effects:

[0016] (1) The online metering device for material consumption in the silk-making workshop described in this utility model uses a conductive component installed in the connecting pipe to make the screened material come into contact with it, and the static electricity carried by it is completely released, so as to avoid the light material adsorbing on the inner wall of the device and affecting the accuracy of the metering data.

[0017] (2) The online metering device for material consumption in the silk-making workshop described in this utility model has a buffer belt that can slow down the downward movement speed of the material. On the one hand, it can increase the contact time between the material and the conductive components and enhance the conductivity. On the other hand, the slowing down of the material falling speed can reduce the impact force of the material falling onto the belt scale and prevent the material from being bounced up and affecting the weighing.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example: Figures 1-5 The illustrated online material consumption metering device for a silk-making workshop includes a frame 1 and a belt scale 5 installed inside the frame 1. The belt scale 5 has a feed hopper 3 on its top and a connecting pipe 4 fixedly connected to the bottom of the feed hopper 3. A conductive component 9 is installed inside the connecting pipe 4. The conductive component 9 is grounded so that static electricity can be released when the material comes into contact with it. It includes a set of staggered inclined conductive plates 91 and through slots 92 opened on the conductive plates 91. The material falling onto the conductive component 9 slows down its falling speed through the conductive plates 91. At the same time, under the action of the buffer belt 93 fixedly connected to the conductive plates 91, the material is made to contact the conductive component 9 as much as possible.

[0026] In this embodiment, lightweight materials such as tobacco shreds screened out during the tobacco processing workshop fall into the timed feeding mechanism 2. The timed feeding mechanism 2 intermittently conveys the material to the feed hopper 3. The material comes into contact with the conductive component 9 in the connecting pipe 4, releasing the static electricity it carries. At the same time, the Z-shaped design of the conductive plates 91, combined with the buffer strip 93 on the conductive plates 91, greatly reduces the falling speed of the material, increases the contact time between the material and the conductive plates 91, releases the static electricity carried by the material as much as possible, and reduces the error between the amount of material conveyed by the timed feeding mechanism 2 and the amount of material received by the belt scale 5. After completing one weighing, the belt scale 5 discharges the material into the receiving bucket 7, which is then recovered by the negative pressure pipe 8. The weighing data of the belt scale 5 each time is displayed on the display screen 10.

[0027] Specifically, such as Figures 1-3As shown, a timed feeding mechanism 2 is provided at the top of the feeding hopper 3. The timed feeding mechanism 2 is fixedly connected to the screening machine, and its discharge port is matched with the feeding hopper 3. A guide plate 6 is provided at the bottom of the forward direction end of the belt scale 5. The guide plate 6 is fixedly connected to the frame 1. A display screen 10 is installed on one side of the top of the frame 1. The guide plate 6 is inclined downward. A receiving bucket 7 is provided at the lower end of the guide plate 6. The lower end of the guide plate 6 extends into the receiving bucket 7. A negative pressure pipe 8 is fixedly connected to the bottom of the receiving bucket 7. The receiving bucket 7 is connected to the negative pressure pipe 8. One end of the negative pressure pipe 8 is connected to a negative pressure fan. A support component is installed outside the negative pressure pipe 8 to contact the ground.

[0028] In this embodiment, the timed feeding mechanism 2 adopts an intermittent feeding method, which can be achieved by a periodically opening and closing rotary valve. The feeding interval of the timed feeding mechanism 2 is matched with the weighing interval of the belt scale 5, with one feeding corresponding to one weighing. The inner walls of the timed feeding mechanism 2, the feeding hopper 3, and the connecting pipe 4 are all coated with anti-static coatings. Before the material comes into contact with the conductive component 9, the static electricity it carries may not be completely released. When the material comes into contact with the inclined conductive component 9, the conductive component 9 releases the static electricity carried by the material and slows down the falling speed of the material. After the belt scale 5 weighs the material, the material moves with the belt scale 5 and enters the receiving bucket 7 through the guide plate 6. The receiving bucket 7 is connected to the negative pressure pipe 8. The negative pressure fan is started to recover the weighed material. The weighing data of the belt scale 5 will be displayed on the display screen 10 for data recording and analysis.

[0029] Specifically, such as Figures 3-5 As shown, the buffer strips 93 on the conductive plate 91 are a group, and the height of the buffer strips 93 gradually increases from the downward tilt of the conductive plate 91; the entire group of conductive plates 91 is inclined Z-shaped, and the through groove 92 is located at the lower end of the conductive plate 91.

[0030] In this embodiment, when the material comes into contact with the inclined conductive plate 91, it moves towards the lower end of the conductive plate 91 and falls through the channel 92 onto the next conductive plate 91, and so on, until the material is discharged and falls onto the belt scale 5. During the process of the material coming into contact with a set of conductive plates 91, its downward movement speed can be slowed down. At the same time, multiple protruding buffer strips 93 are provided on the conductive plate 91. Their material is the same as that of the conductive plate 91, which further increases the contact time between the material and the conductive plate 91, enhances the conductivity, and releases the static electricity that has not been discharged by the antistatic coating. The protrusion height of the buffer strips 93 is low, and on the inclined conductive plate 91, it only serves to buffer the downward movement speed of the material and will not cause material interception.

[0031] Working principle: The screened material enters the timed feeding mechanism 2, which intermittently feeds the material into the feed hopper 3. The material falls and comes into contact with the conductive component 9. The inclined conductive plate 91 moves downward, slowing down the material's downward speed. The grounded conductive plate 91 releases the static electricity from the material in contact with it. The buffer strip 93 on the conductive plate 91 further slows down the material's downward speed and increases the contact time between the material and the conductive component 9, ensuring that the static electricity can be completely released and preventing material adsorption. The material fed in each timed feeding falls onto the belt scale 5 and is weighed by the belt scale 5. Before the material leaves the belt scale 5, the timed feeding mechanism 2 will not transport the material. After weighing, the material is discharged by the guide plate 6 into the receiving bucket 7, which is connected to the negative pressure pipe 8. Finally, the negative pressure pipe 8 recovers the material. The weighing data of the belt scale 5 for each weighing is displayed on the display screen 10 for data analysis.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
