Description

Technical Field

[0001] The utility model belongs to the field of automatic control of silk production equipment, and in particular relates to an intermittent quantitative feeding system with an automatic blocking device. Background Art

[0002] With the rapid advancement of technology, production workshops are becoming increasingly automated, and the demands on the production environment are becoming increasingly stringent. While reducing labor costs, the production environment, quality, and efficiency must also be maintained or even improved. The vacuum rehydration production model dictates that flakes are added to each module's feeding process in separate bins. This inevitably requires a certain amount of time and space between bins when feeding. Therefore, electronic scales are used to control the intermittent feeding of material to prevent a continuous supply of flakes on the conveyor belt when no bins are available. However, during these intervals, flakes on the conveyor belt can fall to the ground due to various factors, impacting the production environment and increasing labor costs for production operators. Some flakes can also fall onto the chain conveyor below, disrupting normal equipment operation and posing a potential risk. Therefore, analyzing the cause of this problem and identifying appropriate improvements are urgent. Utility Model Content

[0003] This application is used to solve the problem of slices falling when adding slices, improve the production and operation functions of the equipment, improve the production site environment, reduce production costs, and eliminate potential safety hazards.

[0004] A first aspect of the present application provides an intermittent quantitative feeding system including an automatic blocking device, the intermittent quantitative feeding system comprising: an electronic scale conveyor belt;

[0005] A box conveyor is provided below the end of the electronic scale conveyor belt;

[0006] An automatic blocking device is provided at the end of the electronic scale conveyor belt. The automatic blocking device has a baffle, and the baffle is configured as follows:

[0007] When the electronic scale conveyor belt is running, the baffle rotates and opens in a direction away from the electronic scale conveyor belt so that the materials on the electronic scale conveyor belt can fall into the box on the box conveyor below;

[0008] When the electronic scale conveyor belt stops, the baffle rotates toward the electronic scale conveyor belt until it fits the end of the electronic scale conveyor belt, blocking the material and preventing the material on the electronic scale conveyor belt from falling when there is no box on the box conveyor below.

[0009] Preferably, the automatic blocking device further comprises: a cylinder, a crank rocker mechanism;

[0010] The crank rocker mechanism is in transmission connection with the baffle;

[0011] The cylinder is configured to drive the crank rocker mechanism to move, thereby driving the baffle to move.

[0012] Preferably, the bottom of the baffle has a sealing strip for achieving sealing and preventing the baffle from scratching the electronic scale conveyor belt. Preferably, the sealing strip is made of silicone or rubber.

[0013] Preferably, the cylinder is configured to move synchronously with the start and stop of the electronic scale conveyor belt:

[0014] When the electronic scale conveyor belt is started, the smoke container is located directly below the electronic scale conveyor belt, and the piston rod of the cylinder moves upward, thereby driving the baffle to rotate and open in a direction away from the electronic scale conveyor belt;

[0015] When the electronic scale conveyor belt stops, the smoke box has been moved away, and the next smoke box has not yet arrived. At this time, the piston rod of the cylinder moves downward, thereby driving the baffle to rotate toward the electronic scale conveyor belt until it fits the electronic scale conveyor belt, thereby achieving automatic blocking.

[0016] Preferably, the box conveyor is a chain conveyor.

[0017] The utility model has the following advantages and effects:

[0018] 1. The intermittent quantitative feeding system with an automatic blocking device in this application eliminates the problem of flakes falling during the flake addition process. This system has a clear structure, is easy to manufacture, uses simple materials, and has low procurement costs. With the addition of the automatic blocking device, the system's baffles automatically open and close with the start and stop of the electronic scale conveyor, preventing flakes from falling, reducing the workload of cleaning personnel, ensuring stable equipment operation, and eliminating safety hazards.

[0019] 2. This solution is highly scalable and can be extended from the flake-feeding process to other similar processes requiring intermittent quantitative feeding. Specifically, a crank-rocker mechanism can be installed at the feed opening, tailored to the production environment and equipment requirements. The power source is not limited to a pneumatic cylinder. Intermittent quantitative feeding can be achieved without material dropouts by rotating the electronic scale conveyor belt and the crank-rocker mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] To address the problem of slices dropping from the electronic scale conveyor belt in the existing slice adding process, this application adopts an intermittent quantitative feeding system with an automatic blocking device. This system effectively solves the problem of slices dropping from the connection between boxes, greatly improves the production site environment, effectively reduces labor and production costs, and eliminates safety hazards and other potential risks.

[0034] An intermittent quantitative feeding system with an automatic blocking device, the intermittent quantitative feeding system comprising: an electronic scale conveyor belt 1;

[0035] A box conveyor 2 is provided below the end of the electronic scale conveyor belt 1;

[0036] An automatic blocking device is provided at the end of the electronic scale conveyor belt 1. The automatic blocking device has a baffle 3. The baffle 3 is configured as follows:

[0037] When the electronic scale conveyor belt 1 is running, the baffle 3 rotates and opens in a direction away from the electronic scale conveyor belt 1 so that the materials on the electronic scale conveyor belt 1 can fall into the smoke box 7 on the box conveyor 2 below;

[0038] When the electronic scale conveyor belt 1 stops, the baffle 3 rotates toward the electronic scale conveyor belt 1 until it is in contact with the end of the electronic scale conveyor belt 1, blocking the material and preventing the material on the electronic scale conveyor belt 1 from falling when there is no smoke box 7 on the box conveyor 2 below.

[0039] Specifically, the automatic blocking device includes a cylinder 6, a crank-rocker mechanism, a swing shaft 4, and a baffle 3. The cylinder 6, which provides the power source, is mounted on the right side of the electronic scale conveyor belt 1. A crank 5 is attached above the cylinder 6, and the swing shaft 4 is connected to the other end of the crank 5. The baffle 3 is fixed to the swing shaft 4. This system operates by controlling the start and stop of the electronic scale conveyor belt 1. Power is supplied by the cylinder 6, transmitted by the crank-rocker mechanism, and released and blocked by the opening and closing of the baffle 3, thus achieving the automatic blocking function.

[0040] The automatic blocking system for the electronic flake feeding scale is designed to prevent flakes from falling at the flake feeding scale. This intelligent blocking system includes a cylinder 6, a crank-rocker mechanism, and a baffle 3. The crank-rocker mechanism is controlled by cylinder 6 to start and stop, thereby driving baffle 3.

[0041] When the electronic scale conveyor belt 1 is running, the baffle 3 rotates clockwise to open, and the slices fall into the smoke box 7 below; when the electronic scale conveyor belt 1 stops, the baffle 3 rotates counterclockwise to fit to the end of the electronic scale conveyor belt 1, blocking the material and preventing the slices from falling when there is no box below.

[0042] This automatic blocking system can ensure that no slices fall off at the electronic scale where slices are added under normal production conditions, thus improving the production and operation functions of the equipment, reducing costs, and eliminating potential hazards.

[0043] In a preferred embodiment, the cylinder 6 is configured to move synchronously with the start and stop of the conveyor belt:

[0044] When the electronic scale conveyor belt 1 is started, the smoke box 7 is located directly below the electronic scale conveyor belt 1. At this time, the piston rod of the cylinder 6 moves upward, thereby driving the baffle 3 to rotate and open away from the electronic scale conveyor belt 1, so that the slices can fall into the smoke box 7.

[0045] When the electronic scale conveyor belt 1 stops, the smoke box 7 has been moved away, and the next smoke box 7 has not yet arrived. At this time, the piston rod of the cylinder 6 moves downward, thereby driving the baffle 3 to rotate toward the electronic scale conveyor belt 1 until it is in contact with the electronic scale conveyor belt 1. The baffle 3 prevents the remaining sheets from falling to the ground due to uncontrollable factors such as slight vibrations or airflow, thereby achieving automatic blocking.

[0046] The working mode of this device is:

[0047] When the piston rod of the cylinder 6 moves upward, the crank 5 drives the swing shaft 4 to rotate, and the baffle 3 fixed on the swing shaft 4 swings clockwise with the swing shaft 4, releasing the material (such as thin sheets) on the electronic scale conveyor belt 1; when the piston rod of the cylinder 6 moves downward, the baffle 3 rotates counterclockwise with the swing shaft 4 and fits to the end of the conveyor belt, blocking the remaining material (such as thin sheets) on the electronic scale conveyor belt 1.

[0048] The components work as follows:

[0049] (1) The electronic scale conveyor belt 1 feeds a fixed amount of thin slices into the cigarette box. The thin slices are weighed by the electronic scale and transported to the end of the electronic scale conveyor belt 1, where they fall into the cigarette box below the end of the conveyor belt. After each cigarette box is filled with a certain amount of thin slices, it is transported away by the chain conveyor belt. The next cigarette box enters the loading station for filling. While waiting for the next cigarette box to arrive, the electronic scale conveyor belt 1 is in a stopped state, at which time a time gap occurs.

[0050] (2) The cylinder 6 is powered by an air source. When the electronic scale conveyor belt 1 starts to transport the sheet, the air source switch is turned on to provide air to the cylinder 6; when the electronic scale conveyor belt 1 stops, the air source switch is turned off.

[0051] (3) The crank-rocker mechanism completes the release and material blocking functions. When the cylinder 6 is activated by air, it pushes upward, pushing one end of the crank 5 upward. The other end of the crank 5 drives the swing shaft 4 and the baffle 3 to rotate clockwise away from the electronic scale conveyor belt 1, thereby releasing the sheet and causing it to fall into the smoke box 7 below. When the air source is turned off, the cylinder 6 resets, the crank 5 moves downward, and the swing shaft 4 and the baffle 3 rotate counterclockwise until they are in contact with the electronic scale conveyor belt 1, blocking the material.

[0052] The technical scheme of the utility model is described in further detail in combination with the installation implementation process. Determine the model of the cylinder 6; according to the selected model of the cylinder 6, design and make the matched cylinder 6 support. Meanwhile, make the crank 5, the swing shaft 4, the baffle 3 and other connecting components. Open holes and tap screws at the corresponding positions of the original cover head, for fixing the cylinder 6 support and installing the swing shaft 4. The baffle 3 is fixed on the swing shaft 4 of the crank rocker mechanism by bolts. Soft material is additionally installed at the contact part of the baffle 3 and the electronic scale conveying belt 1, to improve the sealing effect and avoid scratching the electronic scale conveying belt 1. Install the cylinder 6, the swing shaft 4 with the baffle 3, the crank 5 and other connecting components. The required compressed air of the cylinder 6 is led out from the air source pipe of the logistics line, and the required pressure is small, which does not affect the operation of the logistics line. The operator needs to check whether the pressure and state of each switch and the material blocking device are normal before operation, and closes the corresponding air source switch after production.

[0053] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application and not to limit them; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the specific implementation of the present application can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solutions of the present application, they should be covered in the scope of the technical solutions claimed by the present application.
