Description

Technical Field

[0001] This application belongs to the field of plastic processing, and particularly relates to a connecting device and an in-line resin modification and molding device. Background Art

[0002] Resin modification refers to changing the molecular structure or chemical properties of resin through physical or chemical means, so as to improve its performance or endow it with new properties. The modified resin may be improved in terms of processability, heat resistance, corrosion resistance, and mechanical properties. The molding process after resin modification mainly uses the modified resin for various molding operations, such as injection molding, extrusion molding, blow molding, etc. Based on the improvement of the LFT-D (Long Fiber Reinforced Thermoplastics Direct Molding) technology, the prior art has proposed an in-line resin modification and molding device, which integrates the modification and molding of plastics, improving the quality and performance of plastic products.

[0003] The in-line resin modification and molding device in the prior art integrates the modification and processing and molding of resin, and can realize continuous operation at different stages. During this operation process, a connecting device needs to be set up to connect the modification system and the molding system to achieve an integrated effect, and the melt from the modification system is sent into the molding system through the transportation of the connecting device.

[0004] The above-mentioned in-line resin modification and molding device improves production efficiency and production quality. However, in the actual production process, the connecting device needs to be connected to the extruder of the modification system, and the extruder often needs to be disassembled to replace and clean the screw. Due to the existence of the connecting device, the disassembly work becomes more complicated. It is necessary to first disassemble various components of the connecting device, and then the screw can be disassembled, making the work of disassembling the screw complicated, time-consuming and laborious. Summary of the Invention

The sealing block is at the same horizontal position as the feed channel and the feed inlet, and the screw can be disassembled through the feed inlet and the feed channel.

[0007] Optionally, the first end face is recessed towards the second end face to form an arc shape adapted to the side wall of the discharge channel.

Detailed implementation manners

[0029] The following elaborates on the detailed implementation manners of the present application through embodiments. However, the specific implementation of the present application does not limit the technical solutions of the present application. Any non-substantive changes such as replacing common technical solutions in the art using the technical solutions described in the embodiments of the present application belong to the protection scope of the present application. Additionally, it should be noted that the cross-section of the sealing block can be of any shape as long as it can achieve the purpose of allowing the screw to pass through. An overflow device or a melt buffer device is provided on the connecting device, and no further detailed introduction will be given. Those skilled in the art should understand and know this.

[0030] Embodiment 1

[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the connecting device 1 includes a feed inlet 11, a discharge outlet 12, a feed channel 13, a discharge channel 14, and further includes a sealing block 15. One end of the sealing block 15 close to the feed inlet 11 is the first end face 151, and the end far from the discharge outlet 12 is the second end face 152. The sealing block 15 is in the same horizontal position as the feed channel 13 and the feed inlet 11. When it is necessary to replace or clean the screw, the sealing block 15 is removed, and the screw passes through the feed inlet 11, the feed channel 13, and the channel of the sealing block 15 at the connecting device 1 in sequence, so as to achieve the purpose of being able to remove the screw without disassembling the connecting device 1.

[0032] The first end face 151 is recessed towards the second end face 152 to form an arc shape adapted to the side wall of the discharge channel 14. Tilted convex portions 153 are formed on both sides of the arc shape. When the melt enters the discharge channel 14 through the feed channel 13, due to the existence of the tilted convex portions 153 and the arc-shaped end face, it plays a buffering role for the melt, reducing the influence on the melt performance caused by the equipment structure. At the same time, it guides the melt into the discharge channel 14. The second end face 152 is provided with an extension portion 154, and the extension portion 154 is in a stepped shape, which plays a role in fixing the sealing block 15 and facilitates the disassembly of the sealing block 15. The diameter of the discharge channel 14 is smaller than the radial distance of the feed channel 13. The sealing block 15 and the feed channel 13 are both in a runway shape and correspond to each other, facilitating the disassembly of the screw.

[0033] The front end of the convex portion 153 of the sealing block 15 is located at the middle position between the discharge port 12 and the overflow port. The cross-section of the feed channel 13 is in a runway shape. In other embodiments, the front end of the convex portion 153 of the sealing block 15 can be in contact with the edge of the connecting device 1. At this time, the cross-sectional area of the feed channel 13 becomes smaller, which is beneficial to the flow of the melt and will not cause the melt to stay in the feed channel 13 for too long and affect the performance of the melt. The feed channel 13 can also be of other shapes as long as it can achieve the flow of the melt. Further, the cross-sectional shape of the sealing block 15 can also be of other shapes as long as it can achieve the disassembly of the screw.

[0034] The connecting device 1 further includes a buffer channel 21. The melt enters the buffer device 2 through the buffer channel 21, thereby temporarily storing the melt. It also includes a mounting groove 31. The overflow device 3 is connected to the connecting device 1 through the mounting groove 31, and the excess melt in the equipment is discharged through the overflow hole 32 during the required working stage.

[0035] Embodiment 2

[0036] As Figure 6 shown in the connecting device 1, the same technical features as in Embodiment 1 will not be repeated. The difference is that in this embodiment, the buffer channel 21 is not provided, and only the mounting groove 31 is provided. That is to say, the connecting device 1 only connects the overflow device 3 and does not connect the buffer device 2.

[0037] Embodiment 3

[0038] As Figure 7 and Figure 8 shown in the connecting device 1, the same technical features as in Embodiment 1 will not be elaborated. The difference is that in this embodiment, the mounting groove 31 is not provided, and only the buffer channel 21 is provided. That is to say, the connecting device 1 only connects the buffer device 2 and does not connect the overflow device 3.

[0039] Embodiment 4

[0040] As Figure 9 and Figure 10The connecting device 1 shown, the technical features identical to those of the embodiment will not be described again. The difference lies in that in this embodiment, the buffer channel 21 and the mounting groove 31 are no longer provided. That is to say, the connecting device 1 is no longer connected to the buffer device 2 nor to the overflow device 3.

[0041] Of course, in other embodiments, other devices can be provided as needed and connected to this connecting device 1.

[0042] Embodiment 5

[0043] Such as Figure 11 A resin on-line modification and molding device as shown, which includes the connecting device 1 of Embodiment 1, and further includes a modification system 4 and a molding system 5. The modification system 4 includes an extruder 41, and the molding system 5 includes a storage cylinder 51 and a nozzle 52.

[0044] Of course, in other embodiments, the connecting device 1 can also be connected to the resin on-line modification and molding device in the manner of Embodiment 2 or Embodiment 3 or Embodiment 4 above.
