Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of rubber scrap granule packaging technology, and more specifically, to a weighing and packaging device for rubber scrap granules. Background Technology

[0002] In existing rubber scrap granule packaging lines, traditional plastic woven bags are commonly used. These bags have high electrical resistance and are soft and amorphous, while the rubber scrap granules are rich in carbon black and plasticizers. During the feeding process, the two materials rub against each other, creating a high electrostatic field that causes granules to stick to the bag opening and dust to accumulate, affecting subsequent bagging. Therefore, a weighing and packaging device for rubber scrap granules with an anti-static mechanism is designed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a weighing and packaging device for rubber scrap granules.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses a weighing and packaging device for rubber scrap granules, including a weighing and packaging mechanism. The weighing and packaging mechanism includes a support frame, a measuring hopper, a discharge hopper, a packaging bag clamping component for holding the packaging bag, and a control terminal. The packaging bag clamping component includes a discharge hopper. A rubber scrap granule bagging antistatic component is provided on the outer side of the bottom of the discharge hopper. The rubber scrap granule bagging antistatic component includes an ion air ring, a suction ring, and a fan. The suction ring is located on the outer side of the ion air ring and is coaxially arranged. Rubber scrap granule packaging bag positioning components are provided on both sides below the discharge hopper.

[0005] Preferably, the bottom side of the ion wind ring has several air outlet holes, and its interior is hollow, serving as an air outlet cavity. Several high-voltage needles are equidistantly installed inside the ion wind ring. The high-voltage needles are connected to a battery box via power lines. The battery box contains a battery and a boost module.

[0006] Preferably, the output terminal of the battery is electrically connected to the input terminal of the boost module via a wire, and the output terminal of the boost module is electrically connected to the input terminal of the high-voltage needle via a power cord.

[0007] Preferably, the bottom of the suction ring has several suction ports, the inside of the suction ring is hollow and serves as a suction chamber, and the suction ring and the ion ring are respectively connected to the fan through pipes.

[0008] Preferably, the air intake and the air outlet are offset, and the height of the air outlet is 30-40mm higher than that of the air intake.

[0009] Preferably, the suction ring and the ion ring are connected to the discharge hopper by clamps and are located on the outer side of the bottom end of the discharge hopper.

[0010] Preferably, the positioning component for the rubber scrap granule packaging bag includes an electric push rod c, an abutment plate, and an adsorption component for adsorbing the rubber scrap granule packaging bag. The electric push rod c is installed on the inner side of the support frame, and the abutment plate is screwed to the front end of the electric push rod c.

[0018] like Figure 1-6 As shown, this utility model provides a weighing and packaging device for rubber scrap granules, including a weighing and packaging mechanism 1. The weighing and packaging mechanism 1 includes a support frame 11, a metering hopper 12, a discharge hopper 13, a packaging bag clamping component 14 for clamping packaging bags, and a control terminal 15. The packaging bag clamping component 14 includes a discharge hopper 141. A rubber scrap granule bagging antistatic component 2 is provided on the outer side of the bottom of the discharge hopper 141. The rubber scrap granule bagging antistatic component 2 includes an ion air ring 21, a suction ring 22, and a fan 222. The suction ring 22 is located on the outer side of the ion air ring 21 and is coaxially arranged. Rubber scrap granule packaging bag positioning components 3 are provided on both sides below the discharge hopper 141.

[0019] Furthermore, in this embodiment, the bottom side of the ion wind ring 21 is provided with several air outlet holes 211, which are hollow inside and serve as air outlet chambers. The air outlet chambers provide air outlet channels, allowing the air from the fan 222 to be blown out from the air outlet holes 211 through the air outlet chambers. Several high-pressure needles 212 are equidistantly installed inside the ion wind ring 21. The high-pressure needles 212 are connected to the battery box 213 via power lines. The battery box 213 contains a battery and a boost module.

[0020] It should be noted that ordinary batteries only have 12V (or 24V), while the high-voltage needle 212 requires 7-10kV to generate corona ionization. The low-voltage DC of the battery must be boosted to kV through a boost module in order to drive the high-voltage needle 212 to generate positive and negative ions.

[0021] In this embodiment, the output terminal of the battery is electrically connected to the input terminal of the boost module via a wire, and the output terminal of the boost module is electrically connected to the input terminal of the high-voltage needle 212 via a power cord. The battery provides power to the high-voltage needle 212 through the boost module, generating positive and negative ions. The air is then ventilated into the ion ring 21 by the fan 222, and the air carrying positive and negative ions is output from the air outlet of the ion ring 21 to perform static electricity removal treatment on the packaging bag clamped on the discharge port.

[0022] The principle of static electricity removal by the ion wind ring 21 is as follows: the high-voltage needle 212 discharges in the air and generates a large number of positive and negative ions. The fan 222 blows these ions evenly toward the bag opening and the particles. When the ions meet the static charge, the positive and negative charges cancel each other out, the potential drops to a safe value, and the static electricity is removed.

[0023] It should be noted that the routing of the power cord and wires, as well as the circuit connection methods, structures, and diagrams of the boost module, battery, and high-voltage needle 212, can be selected by technicians according to conventional routing and setting methods, and will not be elaborated further.

[0024] In this embodiment, the bottom of the suction ring 22 is provided with several suction ports 221. The inside of the suction ring 22 is hollow and serves as a suction chamber. The suction ring 22 and the ion ring 21 are respectively connected to external fans 222 through pipes. The fan 222 connected to the ion ring 21 blows air, and the fan 222 connected to the suction ring 22 draws air.

[0025] In this embodiment, the air inlet 221 and the air outlet 211 are offset, with the air outlet 211 being 30-40mm higher than the air inlet 221. This causes the ion air ring 21 to blow downwards, and the air suction ring 22 is then set down 30-40mm, coaxial with the ion air ring 21, and also sucks downwards, forming a stepped design of blowing first and then sucking. The ion air first sweeps across the packaging bag opening to remove static electricity, and the dust from the rubber scrap particles is blown away. When it reaches the position of the air suction ring 22, it is immediately drawn away, so they do not compete for airflow and the particles are not sucked away.

[0026] It should be noted that the airflow of the suction ring 22 and the ion ring 21 must be connected to ensure that there is no conflict.

[0027] In this embodiment, the suction ring 22 and the ion ring 21 are connected to the discharge hopper 141 by a clamp and are located on the outer side of the bottom end of the discharge hopper 141. This allows the suction ring 22 and the ion ring 21 to be placed between the clamping plate 143 and the upper end of the rubber scrap granule packaging bag 4 when the packaging bag clamping member 14 controls the clamping plate 143 at its end to clamp the upper end of the rubber scrap granule packaging bag 4 by the electric push rods b142 set on both sides. This allows the ion ring 21 and the suction ring 22 to provide antistatic protection for the upper end of the rubber scrap granule packaging bag 4.

[0028] In this embodiment, the positioning component 3 for the rubber scrap granule packaging bag includes an electric push rod c31, an abutment plate 32, and an adsorption component for adsorbing the rubber scrap granule packaging bag 4. The electric push rod c31 is installed on the inner side of the support frame, and the abutment plate 32 is screwed to the front end of the electric push rod c31. The electric push rod c31 controls the abutment plate 32 to move towards the rubber scrap granule packaging bag 4.

[0029] In this embodiment, the adsorption component includes two vacuum suction cups 33 and a vacuum pump 34. The vacuum suction cups 33 are screwed to the inner side of the abutment plate 32. The vacuum suction cups 33 are connected to the vacuum pump 34 through pipes. The vacuum pump 34 performs vacuum treatment on the rubber scrap granule packaging bag 4 located at the vacuum suction cups 33, adsorbing the rubber scrap granule packaging bag 4 onto the inner surface of the abutment plate 32 to stabilize the position of the rubber scrap granule packaging bag 4.

[0030] In this embodiment, the abutment plate 32 has an arc-shaped design and is made of metal. Soft foam is fixed to the inside. The metal material makes the abutment plate 32 highly rigid, so it will not warp during long-term vacuum adsorption. The soft foam adheres to the surface of the packaging bag, preventing wrinkles and local vacuum failure.

[0031] In this embodiment, the weighing hopper 12 is disposed on the top of the support frame 11. The weighing hopper 12 is used to weigh the imported rubber scrap particles. The weighing function can be realized by a weighing sensor, and the weight of the rubber scrap particles can be viewed by sending a weighing signal to the control terminal 15. After the required weight is reached, the electric push rod a121 disposed on the bottom side of the weighing hopper 12 controls the baffle 122 disposed at its end, which is used to block the weighing hopper 12 from the unloading hopper 13, to move backward and open, so that the rubber scrap particles are introduced into the unloading hopper 13. The unloading hopper 13 is disposed at the output port of the weighing hopper 12, and the packaging bag clamp 14 is disposed in the unloading hopper 13. Below, the valve at the output port of the unloading hopper 13 is opened, and the rubber scrap particles enter the discharge hopper 141. The clamping plate 143 is pre-clamped by the electric push rod b142 at the bottom of the discharge hopper 141, so that the rubber scrap particles can fall into the rubber scrap particle packaging bag 4 for packaging. The control terminal 15 is installed on the outer side. The electric push rod, valve, fan 222 and other components are all controlled by the control terminal 15. Its control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the art. This application will not explain the control method and circuit connection in detail.

[0032] Specifically, based on the existing weighing and packaging mechanism 1, the principle of which will not be elaborated further, the process of antistatic and stable packaging of rubber scrap granules is as follows: S1, the operator puts the empty woven bag onto the lower end of the discharge hopper 141, the bag mouth hangs down naturally, the electric push rods c31 on both sides push the arc-shaped abutment plate 32 (lined with soft foam) to close the bag body, the vacuum pump 34 is started, the vacuum suction cup 33 generates suction force on the back of the foam, the bag body is flexibly attached to the inside of the abutment plate 32 to reduce the shaking of the bag body, and the number of rubber scrap granule packaging bag positioning parts 3 is set according to the length of the bag body to achieve its effect; S2, the electric push rod b142 drives the clamping plate 143 to clamp the upper end of the bag opening from both sides, completing the first mechanical clamping. At this time, the ion wind ring 21 and the suction ring 22 are located inside the bag opening. The control terminal 15 controls the battery + boost module to output 7 kV to the high voltage needle 212 in the ion wind ring 21 to generate positive and negative ions. The fan 222 blows air into the ion wind ring 21, and the air carrying ions sweeps downward across the bag opening. Another fan 222 starts synchronously and sucks air through the suction ring 22. The static electricity at the bag opening is neutralized, the floating dust is sucked away, and the rubber particles continue to fall due to inertia. S3, after the weighing hopper 12 reaches the set value, the electric push rod a121 pulls open the baffle 122, and the particles fall into the bag through the unloading hopper 13 and the discharge hopper 141. The ion wind ring 21 and the suction ring 22 work throughout the process and then close after a 2-second delay until the material is discharged to ensure that there is no residual static electricity and dust.

[0033] S4. After bagging is completed, vacuum pump 34 stops, electric push rod c31 retracts to abutment plate 32, bag body detaches from adsorption, electric push rod b142 releases bag opening, operator / robotic arm picks up bag and seals.

[0034] The weighing and packaging mechanism 1, control terminal 15, high-pressure needle 212, battery box 213, booster module, fan 222, electric push rod vacuum suction cup 33, vacuum pump 34, rubber scrap granule packaging bag 4 and other components of this utility model are all general standard parts or parts known to those skilled in the art.
