Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically an automatic weighing and packaging machine for plastic granules. Background Technology

[0002] Plastic pellets are made from granular plastic raw materials that can be processed into various plastic products through heating, compression and other processes. During their production and processing, they are often weighed and packaged.

[0003] In the prior art, such as the application with application number 202420312587.9, the disclosed title is: "An Automatic Weighing and Packaging Device for Plastic Particles". In this device, a stirring component is set to stir the plastic particles inside the storage cylinder, so as to avoid the particles sticking together and affecting the subsequent processing and packaging effect. A conveyor belt is set to transport the packaged plastic particles, and a weighing component is set to achieve the effect of accurate weighing and packaging of the plastic particles.

[0004] However, in the existing technology, such as the automatic weighing and packaging device for plastic granules mentioned in application number 202420312587.9, the packaging cylinder cannot be limited, which will cause the plastic granules to impact the packaging cylinder when they are fed, causing the packaging cylinder to shift and the plastic granules to spill. At the same time, there is a distance between the material discharge port and the packaging cylinder, which will cause the plastic to splash when it is fed, resulting in the waste of plastic granules.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] To address the problems existing in the prior art, this embodiment provides the following technical solution: an automatic weighing and packaging machine for plastic granules, comprising a conveyor belt 1 and a clamping mechanism 2. The clamping mechanism 2 is located on the upper outer side of the conveyor belt 1, and multiple sets are configured to limit the position of the packaging box 3, ensuring that the packaging box 3 does not shift position when the plastic granules are fed. Simultaneously, an anti-splash mechanism 8 is provided, located below the feeding port 6, which effectively shortens the distance between the feeding port 6 and the packaging box 3 during feeding, ensuring that no splashing occurs when the plastic granules are fed.

[0028] like Figure 1 , Figure 4 and Figure 5As shown, by setting multiple clamping mechanisms 2 on the upper outer side of the conveyor belt 1, the packing box 3 can be placed above the middle of the electronic scale 203. Fixed rods 202 are symmetrically installed on the front and rear sides of the upper end of the electronic scale 203. A clamping plate 201 is slidably set above the fixed rods 202. A connecting pin 204 is installed on the upper end of the clamping plate 201. The connecting pin 204 is located in a groove opened inside the moving plate 205. A first electric push rod 206 is fixedly connected to the middle outer side of the moving plate 205. When the first electric push rod 206 is opened, the output end of the first electric push rod 206 can push the moving plate 205 to move. At this time, the connecting pin 204 will slide inside the moving plate 205. The connecting pin 204 will pull the clamping plate 201 installed at the lower end to move inward from the outside of the fixed rod 202. At this time, the fixed rod 202 can clamp and limit the packing box 3.

[0029] like Figure 2 and Figure 3 As shown, after the packaging box 3 is limited, the conveyor belt 1 can be opened. When the packaging box 3 moves to the middle of the conveyor belt 1, the conveyor belt 1 can be closed. The packaging box 3 will be located below the middle of the support frame 4. The feeding cylinder 5 is installed at the upper middle of the support frame 4. The inside of the feeding cylinder 5 is filled with plastic granules. The feeding port 6 is installed at the lower part of the feeding cylinder 5. The lower end of the feeding port 6 is equipped with a protective hose 801. The lower end of the protective hose 801 is symmetrically equipped with connecting blocks 802 at the front and back. The upper end of the connecting block 802 is equipped with a second electric push rod 803. The second electric push rod 803 can be opened. The output end of the second electric push rod 803 can push the connecting block 802 to move downward. At this time, the protective hose 801 will be stretched, which can effectively shorten the distance between the feeding port 6 and the packaging box 3.

[0030] Simultaneously, a valve 7 is installed inside the feeding port 6. Opening the valve 7 allows the plastic granules inside the feeding cylinder 5 to enter the packaging box 3. The packaging box 3 is located above the center of the electronic scale 203. The electronic scale 203 typically has a load cell inside, usually a strain gauge sensor, which accurately weighs the plastic granules entering the packaging box 3. When the weight of the plastic granules reaches a specific value, it outputs an electrical signal, usually in the mV range, which is transmitted to the controller body 10 located on the front side of the support frame 4 to control... The main body 10 is an LC400 series controller, which amplifies, filters, and performs A / D conversion on the electrical signal. After converting it into a digital signal, it performs logic judgment and outputs instructions, which can trigger the opening and closing of valve 7. That is, when the amount of plastic granules entering the packaging box 3 reaches a certain value, valve 7 can be closed to stop the transmission of plastic granules. At this time, the conveyor belt 1 can be opened again to transport the packaged box 3. Afterwards, the top cover is put on the upper side of the packaging box 3, and the packaging is completed. The packaging box 3 waiting to be loaded can be moved to the middle of the support frame 4 to continue the packaging of plastic granules.

[0031] like Figure 6 As shown, a movable frame 901 is installed inside the feeding cylinder 5. A third electric push rod 903 is installed above the middle of the movable frame 901. When the plastic granules are being fed and packaged, the third electric push rod 903 can be opened. The output end of the third electric push rod 903 can push the movable frame 901 downward. The outside of the movable frame 901 is tightly fitted with the inside of the feeding cylinder 5. That is, when the movable frame 901 moves, it can both agitate the plastic granules to prevent blockage during feeding and prevent the plastic granules from sticking to the inner wall of the feeding cylinder 5. In addition, a push frame 902 is installed at the lower middle of the movable frame 901. The push frame 902 can push the plastic granules to facilitate the feeding of the plastic granules.

[0032] The electric linear actuators mentioned above are all model HB-DJ801.

[0033] The working principle of this automatic weighing and packaging machine for plastic granules is as follows: Multiple clamping mechanisms 2 are set on the upper external side of the conveyor belt 1 to limit the position of the packing box 3, ensuring that the packing box 3 will not shift its position when the plastic granules are fed. At the same time, a feeding component 9 is set inside the feeding cylinder 5 to facilitate feeding. The feeding component 9 can push the plastic granules, which can not only accelerate the feeding of plastic granules, but also prevent plastic granules from sticking to the inner wall of the feeding cylinder 5. In addition, it can also adjust the distance between the feeding port 6 and the packing box 3 to prevent the plastic granules from splashing during feeding.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
