Description

Technical Field

[0001] This utility model relates to the field of plastic masterbatch packaging, specifically an automatic packaging and degassing device. Background Technology

[0002] After the plastic masterbatch is prepared, it needs to be injected into sealed bags and then packaged to form bagged plastic masterbatch. The bags should not be filled too full to ensure easy stacking. Existing packaging equipment directly seals the opening of pre-filled bags, resulting in a significant amount of gas trapped inside. When the sealed bags are laid flat on pallets, the gas buildup causes the top of the bags to bulge, making it unstable when stacking more packaged masterbatch on top (typically requiring a stacking height of 8-10 bags). This leads to slippage, displacement, and difficulty in stacking. Furthermore, the masterbatch is prone to scattering and falling during forklift handling, presenting several drawbacks. If the sealing position of the packaging bag is kept unchanged, and the gas inside the packaging bag is reduced before sealing, it can prevent the top surface of the packaging bag from forming a high bulge when the whole bag of plastic masterbatch is laid flat. This makes stacking easier, improves the stability of stacking, reduces the trouble of scattering and falling during transportation, and improves convenience. Summary of the Invention

[0003] Existing sealing equipment for producing plastic masterbatch suffers from poor venting, resulting in a significant amount of gas trapped inside the packaging bags. This causes the pre-packaged plastic masterbatch bags to bulge when laid flat, leading to poor stability when stacked on pallets, easy slippage and displacement, and scattering during handling. This application provides an automatic packaging and venting device. The device includes an automatic compression venting mechanism that works in conjunction with a sealing machine. The automatic compression venting mechanism bidirectionally compresses the bag pre-filled with plastic masterbatch, narrowing the bag's width. This causes the plastic masterbatch inside to rise towards the bag opening, occupying the space below the opening and venting some of the gas. This reduces the height between the sealing point and the plastic masterbatch, decreasing the space below the bag opening. The bag is then conveyed to the automatic sealing machine for sealing, further reducing the gas inside the plastic masterbatch bag. When the sealed plastic masterbatch bag is placed on a pallet, it will not bulge, resulting in more stable placement.

[0004] The technical solution adopted by this utility model to solve the technical problem is: an automatic packaging and degassing device, including a conveying mechanism, a compression degassing mechanism, and a sealing machine. A sealing bracket is provided at the upper end of the conveying mechanism, and a sealing machine is provided in the sealing bracket. Compression degassing mechanisms are provided on both sides of the sealing bracket below the sealing machine. The two compression degassing mechanisms can simultaneously compress the bag on the conveyor belt of the conveying mechanism and then transport it to the sealing machine for sealing.

[0005] The extrusion and exhaust mechanism includes an extrusion frame, a conveyor belt, a telescopic cylinder, and a drive motor. The telescopic rod of the telescopic cylinder is connected to the extrusion frame. The telescopic cylinder can control the extension or retraction of the extrusion frame to extrude and clamp or release the bag.

[0006] The extrusion and degassing mechanism has several rollers arranged in an array. A conveyor belt is installed at the outer end of each roller. The shaft of the drive motor is connected to the active roller. The rotation of the drive motor controls the rotation of the active roller and the conveyor belt, which in turn drives the clamped bag to be conveyed into the sealing machine.

[0007] When the telescopic cylinders of the extrusion and venting mechanisms on both sides of the sealing bracket extend, they control the two extrusion frames to move closer to each other. The rollers in the extrusion frames press against the conveyor belt to squeeze and clamp the bag on the conveyor belt, thus narrowing the width of the bag. This causes the plastic masterbatch inside the bag to rise upwards towards the bag opening, raising the material level inside the bag and expelling some of the gas from the upper part of the bag. This reduces the distance between the sealing position and the plastic masterbatch, thus reducing the amount of gas inside the bag. When the drive motors in both extrusion frames rotate synchronously, they drive the bag being squeezed and clamped forward. The sealing position of the bag moves to the sealing machine for sealing. After sealing, the bag is output from the end. This process reduces the amount of gas inside the bag containing the plastic masterbatch. When the packaged and sealed plastic masterbatch is placed on the pallet, it will not bulge, and it will be stable when stacked.

[0008] The front and rear ends of the extrusion frame of the extrusion and degassing mechanism are respectively equipped with inductive switches. The inductive switches are connected to the circuit module, which in turn is connected to the telescopic cylinder and the drive motor. The circuit module controls the operation of the telescopic cylinder and the drive motor. The drive motor can be started first by the circuit module. When the bag on the upper end of the conveyor belt passes the inductive switch at the front end of the extrusion frame and enters the extrusion frame, the inductive switch at the front end is activated, and the circuit module controls the telescopic rod of the telescopic cylinder to extend. The extrusion frames of the two extrusion and degassing mechanisms move closer to squeeze and clamp the bag. The drive motor controls the roller conveyor to rotate, and the roller conveyor drives the clamped bag to be conveyed into the sealing machine. After the sealing machine seals the bag, when the bag passes the inductive switch at the rear end of the extrusion frame, the circuit module controls the telescopic rod of the telescopic cylinder to retract, increasing the distance between the two extrusion frames. Then, when the next bag passes the inductive switch at the front end and enters the two extrusion frames, the circuit module controls the telescopic rod of the telescopic cylinder to extend again. This cycle continuously controls the automatic degassing and sealing, realizing automatic packaging, sealing, and degassing.

[0009] The telescopic cylinder of the extrusion exhaust mechanism can be any one of a pneumatic telescopic cylinder, a hydraulic telescopic cylinder, or an electric telescopic cylinder.

[0010] The inductive switch can be either a laser inductive switch or a microwave inductive switch.

[0011] The guide bracket of the transfer mechanism is provided with guide plates on both sides below. When the bottom of the bag pre-loaded with plastic masterbatch enters the guide plate, the bottom of the bag can be initially positioned and guided, so that the bag can accurately enter the two extrusion frames.

[0012] The outer surface of the active roller in the extrusion frame of the extrusion exhaust mechanism can be provided with several textures, which can increase the friction between the roller and the conveyor belt and prevent the conveyor belt from slipping easily during rotation.

[0013] The outer surface of the conveyor belt of the extrusion and degassing mechanism can be provided with a rough surface or texture, which can increase the clamping and conveying friction of the bag during the conveying process and prevent the bag from slipping easily between the bag and the conveyor belt.

[0014] The beneficial effects of this utility model are as follows: An automatic packaging and venting device is provided. A sealing bracket is provided at the upper end of the conveying mechanism, and a sealing machine is provided in the sealing bracket. Extrusion and venting mechanisms are respectively provided on both sides of the sealing bracket below the sealing machine. The two extrusion and venting mechanisms can simultaneously extrude the bag body on the conveyor belt of the conveying mechanism, which narrows the width of the bag body. This causes the plastic masterbatch inside the bag body to rise upwards towards the bag opening, occupying the space below the bag opening and venting some gas. This reduces the height between the sealing position and the plastic masterbatch, and the space below the bag opening becomes smaller. When the bag is then conveyed to the automatic sealing machine for sealing, the gas inside the plastic masterbatch bag can be reduced. When the packaged and sealed plastic masterbatch bag is placed on the pallet, it will not bulge, making the placement more stable. The device has stable performance during use and is more convenient.

Detailed Implementation

[0021] exist Figure 1 In the prior art shown, the bag body 6 is sealed around its perimeter, making it a sealable packaging bag with only the opening exposed. After pre-filling the bag body 6 with plastic masterbatch, the bag body 6 with pre-filled plastic masterbatch is placed on the upper end of the conveyor belt 2 of the transfer mechanism 1 for conveying. The height of the plastic masterbatch stored in the bag body 6 is at the material height position 01. The conveyor belt 2 then transports the bag body 6 to the guide groove below the guide bracket 3, causing the opening of the bag body 6 to shrink and flatten. After that, it continues to be transported to the sealing machine 5 below the sealing bracket 4. The bag body 6 enters the sealing position of the sealing machine 5 through the guide port 7 at the front end of the sealing machine 5. The sealing machine 5 seals the sealing position 02 at the upper end of the bag body 6. The sealed bag of plastic masterbatch is then transported out from the end of the conveyor belt 2 and collected and placed in a pallet for storage. The section between the material height 01 and the sealing position 02 of the sealed bag body 6 is hollow and contains gas. The gas is sealed inside the bag body 6. When the packaged plastic masterbatch bags are laid flat, a high gas bulge will form on the upper surface of the bag body 6. When the bags containing plastic masterbatch are stacked on the upper surface of the bag body 6, it will be unstable and will easily cause the upper plastic masterbatch bags 6 to slide and shift, making them difficult to stack. They are also easy to scatter and fall off when transported by forklift after being stacked, which has certain shortcomings.

[0022] exist Figure 2-4 As shown in this application, an automatic packaging and venting device includes a transfer mechanism 1, a compression venting mechanism, and a sealing machine 5. A sealing bracket 4 is provided at the upper end of the transfer mechanism 1, and a sealing machine 5 is provided in the sealing bracket 4. Compression venting mechanisms are provided on both sides of the sealing bracket 4 below the sealing machine 5. The two compression venting mechanisms can simultaneously compress and transport the bag 6 on the conveyor belt 2 of the transfer mechanism 1.

[0023] The extrusion and exhaust mechanism includes an extrusion frame 8, a conveyor belt 9, a telescopic cylinder 10, and a drive motor 12. The telescopic rod of the telescopic cylinder 10 is connected to the extrusion frame 8, and the telescopic cylinder 10 controls the extension or retraction of the extrusion frame 8.

[0024] The extrusion frame 8 of the extrusion and exhaust mechanism is provided with a number of rollers arranged in a row. A conveyor belt 9 is installed at the outer end of the rollers. The shaft of the drive motor 12 is connected to the active roller 11. The rotation of the drive motor 12 controls the rotation of the active roller 11 and the conveyor belt 9, and the conveyor belt 9 drives the clamped bag 6 to be conveyed into the sealing machine 5.

[0025] When the telescopic cylinders 10 of the extrusion and exhaust mechanisms on both sides of the sealing bracket 4 extend, they control the two opposing extrusion frames 8 to move closer to each other. When the rollers in the extrusion frames 8 press against the conveyor belt 9 to squeeze and clamp the bag body 6 on the conveyor belt 2, the width of the bag body 6 will narrow, causing the plastic masterbatch inside the bag body 6 to rise upwards towards the bag opening position. The material height 01 inside the bag body 6 will rise, expelling some of the gas at the upper end of the bag body 6, thus reducing the distance between the sealing position 02 and the plastic masterbatch, and reducing the gas inside the bag body 6. When the drive motors 12 in the two extrusion frames 8 rotate synchronously, they drive the bag body 6, which is squeezed and clamped, to move forward. The sealing position 02 of the bag body 6 moves to the sealing machine 5 for sealing. After sealing, it is output from the end. This can reduce the gas inside the bag body 6 containing the plastic masterbatch. When the packaged and sealed plastic masterbatch is placed on the pallet, it will not bulge, and it will be stable when stacked.

[0026] The front and rear ends of the extrusion frame 8 of the extrusion and exhaust mechanism are respectively equipped with induction switches 13. The induction switches 13 are connected to a circuit module, which in turn is connected to the telescopic cylinder 10 and the drive motor 12. The circuit module controls the operation of the telescopic cylinder 10 and the drive motor 12. The drive motor 12 can be started first via the circuit module. When the bag 6 on the upper surface of the conveyor belt 2 passes the induction switch 13 at the front end of the extrusion frame 8 and enters the extrusion frame 8, the induction switch 13 at the front end connects to the circuit of the circuit module. The circuit module then extends the telescopic rod of the telescopic cylinder 10, causing the extrusion frames 8 of the two extrusion and exhaust mechanisms to move closer and clamp the bag 6. The drive motor 12 then controls the roller conveyor 9 to rotate, which in turn moves the clamped bag 6 into the sealing machine 5. After the sealing machine 5 seals the bag 6, when the bag 6 passes the induction switch 13 at the rear end of the extrusion frame 8, the circuit module controls the telescopic rod of the telescopic cylinder 10 to retract. The distance between the two extrusion frames 8 increases; then, when the next bag 6 passes the front sensor switch 13 and enters the two extrusion frames 8, the circuit module controls the telescopic rod of the telescopic cylinder 10 to extend again, and the extrusion frames 8 of the two extrusion and exhaust mechanisms approach to squeeze and clamp the bag 6. The conveyor belt 9 drives the clamped bag 6 to be conveyed to the sealing machine 5 for sealing. When the bag 6 passes the sensor switch 13 at the rear end of the extrusion frame 8, the circuit module controls the telescopic rod of the telescopic cylinder 10 to retract, the distance between the two extrusion frames 8 increases, and another sealing is completed. The automatic exhaust and sealing are continuously controlled in a cycle, which can realize automatic packaging, sealing and exhaust.

[0027] The telescopic cylinder 10 of the extrusion exhaust mechanism can be any one of a pneumatic telescopic cylinder, a hydraulic telescopic cylinder, or an electric telescopic cylinder.

[0028] The inductive switch 13 can be either a laser inductive switch or a microwave inductive switch.

[0029] Guide plates 14 are provided on both sides below the guide bracket 3 of the transfer mechanism 1. When the bottom of the bag body 6 pre-loaded with plastic masterbatch enters the guide plate 14, the bottom of the bag body 6 can be initially positioned and guided, so that it can enter the two extrusion frames 8 accurately.

[0030] The outer surface of the active roller 11 in the extrusion frame 8 of the extrusion exhaust mechanism can be provided with several textures, which can increase the friction between the roller and the conveyor belt 9 and prevent the conveyor belt 9 from slipping easily during rotation.

[0031] The outer surface of the conveyor belt 9 of the extrusion and degassing mechanism can be provided with a rough surface or texture, which can increase the clamping and conveying friction of the bag body 6 during the conveying process and prevent the bag body 6 from slipping easily between the conveyor belt 9.

[0032] Yes, and there are no limitations: In this application, an inductive switch may not be used; the working state of the telescopic cylinder 10 and the drive motor 12 can be controlled solely through a circuit module. For example, the circuit module can be configured to control the speed of the conveyor belt 9 to be the same as the speed of the conveyor belt 2 of the transfer mechanism 1, moving 1 meter every 15 seconds. At this time, the bag 6 enters the compression frames 8 of the two compression and exhaust mechanisms (a bag 6 pre-filled with plastic masterbatch is placed in the same position every 15 seconds). The circuit module controls the telescopic rod of the telescopic cylinder 10 to extend, and the two compression frames 8 approach to squeeze, clamp, and convey the bag 6. After 10 seconds, the sealing is completed, completing one sealing and packaging cycle. The circuit module controls the telescopic cylinder 10 to extend its telescopic rod. The telescopic rod of cylinder 10 retracts, increasing the distance between the two extrusion frames 8. After 5 seconds, the second bag 6, pre-filled with plastic masterbatch, enters the extrusion frames 8 of the two extrusion and venting mechanisms. The circuit module controls the telescopic rod of cylinder 10 to extend again, and the two extrusion frames 8 approach to squeeze, clamp, and convey the bag 6. After 10 seconds, the sealing is completed, completing one sealing and packaging cycle. The circuit module controls the telescopic rod of cylinder 10 to retract, increasing the distance between the two extrusion frames 8. This continuous cycle control achieves automatic packaging, sealing, and venting.
