Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a metering packaging machine for rubber powder. Background Technology

[0002] Rubber powder is a powdery substance produced by crushing waste materials generated during the processing of rubber products. It has wide applications in industrial production. During the production of rubber powder, it needs to be metered and packaged for easy storage, transportation, and use.

[0003] Currently, existing rubber powder metering and packaging equipment suffers from problems such as low metering accuracy and low packaging efficiency, making it difficult to meet the needs of large-scale production. Furthermore, during filling, personnel are required to manually press and fix the packaging bag to the outside of the discharge pipe, which increases the workload of personnel and reduces the convenience of packaging. Therefore, we propose a metering and packaging machine for rubber powder to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a metering and packaging machine for rubber powder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A metering and packaging machine for rubber powder includes a frame. A feeding mechanism for conveying the rubber powder is provided on the top of the frame. A controller is fixedly connected to the front of the frame. A top plate and a bottom plate are fixedly connected to the frame from top to bottom. Two weighing sensors are fixedly connected to the top of the top plate. A fixing sleeve is fixedly connected to the top of the two weighing sensors. A weighing hopper is fixedly fitted inside the fixing sleeve. A discharge pipe is fixedly connected to the bottom of the weighing hopper. A gate mechanism is provided on the discharge pipe. A clamping mechanism for clamping and fixing the packaging bag is provided between the discharge pipe and the bottom plate.

[0007] In a preferred embodiment of this utility model, the feeding mechanism includes a feeding cylinder fixedly connected to the top of the frame, a feeding hopper fixedly connected to the top of the feeding cylinder, a feeding motor fixedly connected to one side of the feeding cylinder, an auger fixedly connected to the output shaft of the feeding motor, a discharge pipe fixedly connected to the bottom of the feeding cylinder, and a solenoid valve provided on the discharge pipe.

[0008] In a preferred embodiment of this invention, the weighing sensor, solenoid valve, and feeding motor are all electrically connected to the controller.

[0009] As a preferred embodiment of this utility model, a fixed base is fixedly connected to the top of the frame, and the feeding cylinder is fixedly sleeved inside the fixed base.

[0010] As a preferred embodiment of the present invention, the gate mechanism includes a control box fixedly sleeved inside the discharge pipe, a cylinder fixedly connected to one side of the control box, a sliding plate fixedly connected to the output shaft of the cylinder, a gate plate fixedly connected to one side of the sliding plate, and the gate plate slidably sleeved inside the discharge pipe.

[0011] As a preferred embodiment of this utility model, a sealing sleeve is fixedly fitted on one side of the discharge pipe, and the gate is slidably fitted inside the sealing sleeve.

[0012] In a preferred embodiment of this utility model, the clamping mechanism includes a connecting rod fixedly connected to one side of the gate plate and a sliding groove formed on the front side of the base plate. A gear is rotatably connected to the inner rear wall of the sliding groove. Two sliders are slidably sleeved in the sliding groove. A rack is fixedly connected to the side of the two sliders that are close to each other. The gear meshes with the two racks. A connecting arm is fixedly connected to the front side of each slider. An arc-shaped clamping plate is fixedly connected to the side of the two connecting arms that are close to each other. A vertical plate is fixedly connected to one end of the connecting rod. The vertical plate is fixedly connected to the top of the corresponding connecting arm.

[0013] As a preferred embodiment of this invention, a sealing ring is fixedly connected to the other side of the discharge pipe, and the connecting rod is slidably and sealingly sleeved inside the sealing ring.

[0014] As a preferred embodiment of this invention, anti-slip pads are fixedly connected to the inner sides of both arc-shaped clamps.

[0015] As a preferred embodiment of this utility model, a placement slot for holding packaging bags is fixedly connected to the bottom inner wall of the frame.

[0016] In this utility model, a metering and packaging machine for rubber powder is described. When the solenoid valve and the feeding motor are opened, the feeding motor drives the auger to rotate, which in turn conveys the rubber powder in the feed hopper to the right into the discharge pipe, and finally drops into the weighing hopper. As the rubber powder continues to enter, the value measured by the weighing sensor continues to increase. When the weight of the rubber powder packaging is reached, the controller closes the feeding motor and the solenoid valve in time.

[0017] In this utility model, a metering and packaging machine for rubber powder is described. The packaging bag is placed in the placement trough and fitted over the outside of the discharge pipe. The cylinder is activated, causing the sliding plate and gate to move to the left without blocking the discharge pipe. Simultaneously, the gate moves the connecting rod, vertical plate, a connecting arm, slider, and arc-shaped clamping plate inward. Through the meshing of gears and two racks, the two racks, slider, and arc-shaped clamping plate are driven to approach each other and abut against both sides of the packaging bag, thus clamping and fixing the bag. This eliminates the need for personnel to constantly apply pressure to fix the bag, improving operational convenience. When the weighing sensor returns to zero, it indicates that the rubber powder in the weighing hopper has been discharged. Then, the cylinder is activated in reverse, causing the gate to move to the right to block the discharge pipe. Through the linkage of the connecting rod, the two arc-shaped clamping plates are driven to move away from each other without clamping the packaging bag, allowing the packaging bag to be replaced.

[0018] This utility model has a reasonable structural design. With the cooperation of a weighing sensor, weighing hopper, solenoid valve and feeding mechanism, it can accurately measure the weight of rubber powder and ensure the accuracy of measurement. During packaging, the combination of gate mechanism and clamping mechanism can clamp the packaging bag when the discharge pipe is not blocked, and release the packaging bag when the discharge pipe is blocked. This eliminates the need for personnel to constantly press the packaging bag to fix it, improving the convenience of operation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A metering and packaging machine for rubber powder includes a frame 1. A feeding mechanism 2 for conveying rubber powder is provided on the top of the frame 1. A controller 11 is fixedly connected to the front of the frame 1. A top plate 3 and a bottom plate 10 are fixedly connected to the frame 1 from top to bottom. Two weighing sensors 4 are fixedly connected to the top of the top plate 3. A fixing sleeve 5 is fixedly connected to the top of the two weighing sensors 4. A weighing hopper 6 is fixedly fitted inside the fixing sleeve 5. A discharge pipe 7 is fixedly connected to the bottom of the weighing hopper 6. A gate mechanism 8 is provided on the discharge pipe 7. A clamping mechanism 9 for clamping and fixing the packaging bag is provided between the discharge pipe 7 and the bottom plate 10.

[0026] Furthermore, refer to Figure 1 and Figure 2 The feeding mechanism 2 includes a feeding cylinder 21 fixedly connected to the top of the frame 1. The top of the feeding cylinder 21 is fixedly connected to a feeding hopper 22. A feeding motor 23 is fixedly connected to one side of the feeding cylinder 21. An auger 26 is fixedly connected to the output shaft of the feeding motor 23. A discharge pipe 24 is fixedly connected to the bottom of the feeding cylinder 21. A solenoid valve 25 is installed on the discharge pipe 24. The weighing sensor 4, the solenoid valve 25 and the feeding motor 23 are all electrically connected to the controller 11.

[0027] Using the above scheme: the solenoid valve 25 and the feeding motor 23 are opened, and the feeding motor 23 drives the auger 26 to rotate, which in turn conveys the rubber powder in the feed hopper 22 to the right into the discharge pipe 24, and finally falls into the weighing hopper 6 (which can be equipped with an anti-stick layer inside to reduce the residue of rubber powder and improve the accuracy of metering and packaging). As the rubber powder continues to enter, the value measured by the weighing sensor 4 continues to increase. When the weight of the rubber powder packaging is reached, the controller 11 shuts off the feeding motor 23 and the solenoid valve 25 in time.

[0028] Furthermore, a fixed base is fixedly connected to the top of the frame 1, and the feeding cylinder 21 is fixedly sleeved in the fixed base, which can support and fix the feeding cylinder 21.

[0029] Furthermore, refer to Figure 1 and Figure 3 The gate mechanism 8 includes a control box 81 fixedly fitted inside the discharge pipe 7. A cylinder 82 is fixedly connected to one side of the control box 81. A slide plate 83 is fixedly connected to the output shaft of the cylinder 82. A gate plate 84 is fixedly connected to one side of the slide plate 83. The gate plate 84 is slidably fitted inside the discharge pipe 7.

[0030] Using the above scheme: start cylinder 82, cylinder 82 drives slide plate 83 and gate 84 to move to the left without blocking the discharge pipe 7. When the weighing sensor 4 returns to zero, it means that the rubber powder in the weighing hopper 6 has been discharged. Then start cylinder 82 in reverse, so that it drives gate 84 to move to the right to block the discharge pipe 7.

[0031] Furthermore, a sealing sleeve 85 is fixedly fitted on one side of the discharge pipe 7, and the gate plate 84 is slidably fitted inside the sealing sleeve 85 to improve the sealing performance and prevent the leakage of rubber powder.

[0032] Furthermore, refer to Figure 1 and Figure 4 The clamping mechanism 9 includes a connecting rod 91 fixedly connected to one side of the gate plate 84, and a slide groove 93 opened on the front side of the base plate 10. A gear 99 is rotatably connected to the inner wall of the rear side of the slide groove 93. Two sliders 95 are slidably sleeved in the slide groove 93. A rack 94 is fixedly connected to the side of the two sliders 95 that is close to each other. The gear 99 meshes with the two racks 94. A connecting arm 96 is fixedly connected to the front side of the two sliders 95. An arc-shaped clamping plate 97 is fixedly connected to the side of the two connecting arms 96 that is close to each other. A vertical plate 92 is fixedly connected to one end of the connecting rod 91. The vertical plate 92 is fixedly connected to the top of the corresponding connecting arm 96. A sealing ring 90 is fixedly connected to the other side of the discharge pipe 7. The connecting rod 91 is slidably sealed inside the sealing ring 90. Anti-slip pads 98 are fixedly connected to the inner side of the two arc-shaped clamping plates 97.

[0033] Using the above scheme: the leftward movement of the gate 84 drives the connecting rod 91, vertical plate 92, a connecting arm 96, slider 95, and arc-shaped clamp 97 to move inward. Through the meshing transmission of gear 99 and two racks 94, the two racks 94, slider 95, and arc-shaped clamp 97 will be driven to approach each other and abut against both sides of the packaging bag, thereby clamping and fixing the packaging bag. This eliminates the need for personnel to constantly apply pressure to fix the packaging bag, improving the convenience of operation. When the weighing sensor returns to zero, it indicates that the rubber powder in the weighing hopper 6 has been discharged. Then, the cylinder 82 is started in reverse, causing it to drive the gate 84 to move to the right to block the discharge pipe 7. Through the linkage of the connecting rod 91, the two arc-shaped clamps 97 will be driven to move away from each other and no longer clamp the packaging bag. At this time, the packaging bag can be replaced.

[0034] Furthermore, a placement slot 12 for holding packaging bags is fixedly connected to the bottom inner wall of the frame 1, which facilitates the positioning of the packaging bags.

[0035] In this invention, during use, the controller 11 pre-programs the operating procedures, parameters, and delay times. The controller 11 zeros the two weighing sensors 4, opens the solenoid valve 25 and the feeding motor 23, which in turn drives the auger 26 to rotate. This allows the rubber powder in the feed hopper 22 to be conveyed to the right into the discharge pipe 24, eventually falling into the weighing hopper 6 (which may have an anti-sticking layer to reduce rubber powder residue and improve the accuracy of metering and packaging). As the rubber powder continuously enters, the values ​​measured by the weighing sensors 4 continuously increase. When the weight of the rubber powder package is reached, the controller 11 promptly closes the feeding motor 23 and the solenoid valve 25, places the packaging bag in the placement slot 12, and places it over the outside of the discharge pipe 7. The cylinder 82 is then activated, driving the slide plate 83 and... The gate 84 moves to the left without blocking the discharge pipe 7. At the same time, the gate 84 drives the connecting rod 91, vertical plate 92, a connecting arm 96, slider 95 and arc-shaped clamp 97 to move inward. Through the meshing transmission of gear 99 and two racks 94, the two racks 94, slider 95 and arc-shaped clamp 97 will be driven to move closer to each other and abut against the two sides of the packaging bag, thereby clamping and fixing the packaging bag. This eliminates the need for personnel to constantly apply pressure to fix the packaging bag, improving the convenience of operation. When the weighing sensor 4 returns to zero, it indicates that the rubber powder in the weighing hopper 6 has been discharged. Then, the cylinder 82 is started in reverse, causing it to drive the gate 84 to move to the right to block the discharge pipe 7. Through the linkage of the connecting rod 91, the two arc-shaped clamps 97 will be driven to move away from each other without clamping the packaging bag. At this time, the packaging bag can be replaced.
