DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0035] See also Figure 1-8 , the present invention provides a technical solution:

[0036] A twin-screw extruder head device that is easy to assemble includes a connecting portion 1, a docking portion 2, and an extrusion hole 7 provided on the connecting portion 1, an airbag 3 is installed in the docking portion 2, a clamping block 4 is rotatably connected to the connecting portion 1, a clamping interface 201 adapted to the clamping block 4 is provided on the docking portion 2, a sealing protrusion 301 is provided on the outer side of the airbag 3, and the sealing protrusion 301 is located in the clamping interface 201.

[0037] When the easy-to-assemble twin-screw extruder head device needs to be assembled, the connecting portion 1 is butted against the butt joint portion 2 .

[0038] During the docking process, the card block 4 on the connecting portion 1 is aligned with the card interface 201 on the docking portion 2 .

[0039] Then, the clamping block 4 is rotated to be clamped into the clamping interface 201 , thereby achieving a preliminary connection between the connecting portion 1 and the docking portion 2 .

[0040] When the clamping block 4 is clamped into the clamping interface 201 , the inner wall of the clamping interface 201 will exert a squeezing effect on the airbag 3 located therein.

[0041] Since the sealing protrusion 301 is disposed on the outside of the airbag 3 and the sealing protrusion 301 is located in the card interface 201 , the squeezed airbag 3 will expand and deform, so that the sealing protrusion 301 is tightly fitted with the inner wall of the card interface 201 .

[0042] This tight fit effectively fills the gap between the connecting portion 1 and the butt joint 2, thereby enhancing the sealing of the connection between the two and preventing material from leaking from the connection.

[0043] When disassembly is required, the card block 4 is rotated in the opposite direction to disengage it from the card interface 201 , so that the connecting portion 1 and the docking portion 2 can be separated.

[0044] Sealing convex 301 position design

[0045] Structural characteristics: The sealing protrusion 301 is directly located in the card interface 201 and is in close contact with the card connection block 4.

[0046] Action mechanism: When the card block 4 is inserted into the card interface 201, the airbag 3 is squeezed and expanded, and the sealing protrusion 301 is completely fitted with the inner wall of the card interface 201 to form a physical barrier.

[0047] Adaptive principle: The elastic modulus of the material (such as silicone or rubber) of the airbag 3 is 1-10MPa, and the manufacturing error can be compensated by deformation.

[0048] Sealing redundancy: Even if the gap is ≤0.2mm, the extrusion convex 302 can still maintain a contact pressure of ≥1MPa to ensure sealing reliability.

[0049] Through the cooperation of the card block 4 and the card interface 201, the connection part 1 and the docking part 2 are quickly connected without complicated tools and cumbersome operation steps, which greatly improves the assembly efficiency when replacing and cleaning the extruder head and saves assembly time and labor costs.

[0050] The arrangement of the airbag 3 and the sealing protrusion 301 can effectively enhance the sealing between the connecting portion 1 and the docking portion 2 when the clamping block 4 is clamped into the clamping interface 201 .

[0051] Good sealing performance can prevent the extruded material from leaking at the connection of the die head device, ensuring the normal operation of the twin-screw extruder and improving product quality and production stability.

[0052] The structural design of the device is relatively simple, and is mainly composed of a connecting part 1, a docking part 2, an airbag 3, a clamping block 4 and other components. The connection and matching methods between the components are clear, and it is easy to manufacture and maintain.

[0053] At the same time, this simple structure also reduces the failure rate of the equipment and improves the reliability and service life of the equipment.

[0054] A mounting frame 401 is installed on the connecting part 1 , and a rotating shaft 402 is directly mounted on the mounting frame 401 . A mounting hole 403 is opened at one end of the clamping block 4 . The mounting hole 403 is sleeved on the outside of the rotating shaft 402 . A torsion spring 404 is arranged between the rotating shaft 402 and the mounting hole 403 .

[0055] When the clamping block 4 is clamped into the clamping interface 201 , the included angle between the clamping surface and the vertical line of the rotating shaft 402 is 60°. The 60° angle can provide sufficient friction and self-locking ability to prevent slipping due to vibration.

[0056] In the easily assembled twin-screw extruder head device, the mounting bracket 401 on the connecting portion 1 plays a role in supporting the rotating shaft 402 .

[0057] The rotating shaft 402 is mounted on the mounting frame 401 , and the mounting hole 403 at one end of the clamping block 4 is sleeved on the outside of the rotating shaft 402 , so that the clamping block 4 can rotate around the rotating shaft 402 .

[0058] The torsion spring 404 is installed between the rotating shaft 402 and the installation hole 403. When the clamping block 4 is in the initial state, the torsion spring 404 is in the natural state.

[0059] When it is necessary to connect the connecting part 1 with the docking part 2, rotate the clamping block 4 so that it rotates towards the clamping interface 201 on the docking part 2.

[0060] During the rotation process, the torsion spring 404 undergoes elastic deformation and stores elastic potential energy.

[0061] When the clamping block 4 rotates to align with and snap into the clamping interface 201, the elastic potential energy of the torsion spring 404 causes the clamping block 4 to be tightly clamped within the clamping interface 201, maintaining the connection state between the connecting part 1 and the docking part 2.

[0062] When it is necessary to disassemble the connecting part 1 from the docking part 2, an external force overcomes the elastic force of the torsion spring 404, and the clamping block 4 is rotated in the reverse direction so that it disengages from the clamping interface 201. At this time, the torsion spring 404 resumes deformation, and the connecting part 1 and the docking part 2 can be separated.

[0063] The presence of the torsion spring 404 enables the clamping block 4 to automatically maintain a clamped state after snapping into the clamping interface 201, eliminating the need for additional fixing measures, simplifying the connection structure, improving the stability and reliability of the connection, and ensuring that the head device of the twin-screw extruder does not loosen easily during operation.

[0064] The design of the clamping block 4 rotating around the rotating shaft 402 makes both the connection and disassembly operations relatively convenient.

[0065] Only a small external force needs to be applied to rotate the clamping block 4 to complete the connection or disassembly action, reducing the labor intensity of the operator and improving work efficiency, especially suitable for work scenarios that require frequent assembly and disassembly.

[0066] The combined structure of the mounting bracket 401, the rotating shaft 402, the clamping block 4, and the torsion spring 404 is compact and occupies little space, which is beneficial to the miniaturization design of the head device of the twin-screw extruder.

[0067] A guiding angle 405 is provided at the other end of the clamping block 4.

[0068] In the easily assembled head device of the twin-screw extruder, when performing the assembly operation of the connecting part 1 and the docking part 2, it is necessary to snap the clamping block 4 on the connecting part 1 into the clamping interface 201 on the docking part 2.

[0069] Since a guiding angle 405 is provided at the other end of the clamping block 4, when aligning the clamping block 4 with the clamping interface 201 and approaching it, the guiding angle 405 will first contact the edge of the docking part 2.

[0070] The inclined surface of the guiding angle 405 can guide the movement of the clamping block 4, enabling the clamping block 4 to rotate by itself, so that it can enter the clamping interface 201 without the need for manual deflection by the staff, completing the connection action between the connecting part 1 and the docking part 2.

[0071] The existence of the guide angle 405 enables the card block 4 to be inserted into the card interface 201 more quickly and accurately, eliminating the process of workers manually pulling out the card block 4 during the assembly process, thereby improving the assembly efficiency of the twin-screw extruder head device, especially when frequent assembly operations are required. The advantage is more obvious.

[0072] A groove is provided in the docking part 2, which is not connected to the interior of the docking part 2. The airbag 3 is arranged in the groove, and a docking groove is provided on the outside of the groove. A connecting protrusion adapted to the docking groove is provided on the connecting part 1, and there is a gap between the connecting protrusion and the groove. An extrusion protrusion 302 is connected to the front of the airbag 3, and the extrusion protrusion 302 is adapted to the gap.

[0073] When the connection operation of the easy-to-assemble twin-screw extruder head device is performed, the connection part 1 is butted with the butt joint part 2 .

[0074] The connecting protrusion on the connecting part 1 is aligned with the docking groove on the docking part 2 and inserted into the docking groove. During this process, the connecting protrusion gradually approaches and is inserted into the docking groove.

[0075] Since there is a gap between the connecting protrusion and the groove, as the connecting protrusion is inserted, the airbag 3 located in the groove will be squeezed to a certain extent.

[0076] The airbag 3 will expand and deform after being squeezed, and the squeezing protrusion 302 connected to the front side thereof will move toward the gap as the airbag 3 expands, until the squeezing protrusion 302 fills the gap between the connecting protrusion and the groove.

[0077] At the same time, the sealing protrusion 301 (located in the card interface 201) on the outside of the airbag 3 will further fit tightly with the inner wall of the card interface 201 due to the expansion of the airbag 3, thereby achieving double sealing between the connecting part 1 and the docking part 2, effectively preventing material from leaking from the connection.

[0078] When disassembly is required, the connecting portion 1 is separated from the docking portion 2, the pressure on the airbag 3 disappears, the airbag 3 returns to its original state, the squeezing protrusion 302 withdraws from the gap, and the connecting protrusion is pulled out of the docking groove, completing the disassembly operation.

[0079] The expansion of the airbag 3 allows the extrusion convexity 302 to fill the gap between the connecting convexity and the groove. At the same time, the sealing convexity 301 and the card interface 201 fit tightly together to achieve double sealing, greatly improving the sealing performance between the connecting part 1 and the docking part 2, effectively preventing material leakage, and ensuring the normal operation of the twin-screw extruder and product quality.

[0080] The airbag 3 is arranged in the groove, and the design that the groove is not connected to the inside of the docking part 2 ensures that the airbag 3 has a suitable installation space without affecting other functions and structural integrity of the docking part 2.

[0081] The presence of the airbag 3 enables it to automatically adjust its expansion state according to the degree of extrusion during connection, thereby adaptively filling the gap. Regardless of whether there is a certain manufacturing error in the gap size between the connecting convex and concave groove or a slight change during use, the airbag 3 can achieve a good sealing effect by expanding and deforming, thereby improving the reliability and stability of the seal.

[0082] Each component in this structure is relatively independent, and when the airbag 3 or other components are damaged, it is easy to maintain and replace.

[0083] For example, if the airbag 3 is aged or damaged, the airbag 3 can be easily taken out and replaced with a new one by simply separating the connecting portion 1 from the docking portion 2, thereby reducing the maintenance cost and difficulty of the equipment.

[0084] The cooperation between the connecting protrusion and the docking groove and the filling and squeezing of the connection after the airbag 3 is expanded not only enhances the sealing effect, but also increases the connection stability between the connecting part 1 and the docking part 2 to a certain extent, making the entire twin-screw extruder head device more firm and reliable during operation, and reducing the probability of failure caused by loose connection.

[0085] A filter screen 5 is slidably connected to the connecting part 1 , a latch pin 6 is plugged into the side of the connecting part 1 , a spring 601 is provided between the connecting part 1 and the latch pin 6 , and a plug hole 501 adapted to the latch pin 6 is provided on the filter screen 5 .

[0086] When the filter screen 5 needs to be installed, the filter screen 5 is inserted into the connecting part 1 along the sliding channel of the connecting part 1 .

[0087] During the insertion process, the insertion hole 501 on the filter screen 5 is gradually aligned with the latch pin 6 on the side of the connecting part 1 .

[0088] Since a spring 601 is provided between the connecting portion 1 and the latch 6 , under the initial elastic force of the spring 601 , one end of the latch 6 extends outward.

[0089] When the filter 5 is inserted into place and the socket 501 is completely aligned with the latch 6, the elastic force of the spring 601 will push the latch 6 into the socket 501 of the filter 5, thereby firmly fixing the filter 5 in the connecting part 1 to prevent the filter 5 from moving or falling off during operation.

[0090] When the filter screen 5 needs to be removed for cleaning or replacement, an external force is applied to pull the latch 6 , so that the latch 6 overcomes the elastic force of the spring 601 and moves outward, and is pulled out from the insertion hole 501 of the filter screen 5 .

[0091] At this time, the filter screen 5 loses the fixing effect of the latch pin 6 and can be easily taken out from the connecting part 1 along the sliding channel.

[0092] Through the cooperation between the latch 6 and the spring 601 , the installation and removal of the filter screen 5 are simple and quick.

[0093] When installing, the filter 5 can be automatically fixed by simply inserting it. When disassembling, the filter 5 can be easily taken out by pulling the latch 6 without using additional tools, which greatly improves work efficiency and facilitates daily maintenance and care.

[0094] The elastic force of the spring 601 can ensure that the pin 6 is firmly inserted into the socket 501 of the filter screen 5, so that the filter screen 5 remains stable during the operation of the twin-screw extruder and will not be displaced due to vibration or material pressure, ensuring that the filter screen 5 can filter the material normally and the quality of the extruded product.

[0095] The fixing structure is mainly composed of a filter screen 5, a latch pin 6 and a spring 601, has a simple structure and low manufacturing and installation costs.

[0096] At the same time, the coordination between the various components is clear, easy to understand and maintain, reducing the overall cost and maintenance difficulty of the equipment.

[0097] This fixing method allows the filter 5 to be disassembled and installed separately, which is convenient for regular cleaning or replacement of the filter 5, improves the reusability of the filter 5, extends the service life of the filter 5, reduces the replacement frequency of the filter 5, and thus reduces production costs.

[0098] This structure can fix filter screens 5 of different specifications and sizes in this way as long as the jack 501 thereof matches the latch 6. It has good versatility and adaptability and can meet the installation and fixing requirements of the filter screen 5 in different production needs.

[0099] The top surface of the latch 6 is provided with a chamfer 602 .

[0100] During the process of installing the filter screen 5 to the connecting portion 1 , when the filter screen 5 is inserted along the sliding channel of the connecting portion 1 , the insertion hole 501 on the filter screen 5 will gradually approach the latch 6 .

[0101] Since the top surface of the latch 6 is provided with a chamfer 602 , when the filter 5 approaches the latch 6 , the chamfer 602 first contacts the side surface of the filter 5 .

[0102] As the filter screen 5 continues to be inserted, the latch pin 6 will automatically retract along the inclined direction of the chamfer 602 .

[0103] When the insertion hole 501 is aligned with the latch pin 6 , the latch pin 6 automatically inserts into the insertion hole 501 under the elastic force of the spring 601 , thereby completing the fixing of the filter screen 5 .

[0104] When removing the filter 5, when pulling the latch 6 to remove it from the socket 501, the chamfer 602 can also reduce the contact area between the latch 6 and the filter 5, thereby reducing the friction resistance during the pulling process, making it easier to pull the latch 6 out of the socket 501, thereby smoothly removing the filter 5.

[0105] A pull ring is connected to the side of the latch 6 away from the connecting part 1 , a lifting ring 502 is rotatably connected to the top surface of the filter 5 , a toggle opening 503 is provided on the top surface of the filter 5 , and the toggle opening 503 is located on one side of the lifting ring 502 .

[0106] When the filter screen 5 needs to be removed, the operator holds the pull ring on the side of the latch 6 away from the connecting portion 1 by hand and applies an outward pulling force through the pull ring.

[0107] This pulling force overcomes the elastic force of the spring 601 between the connecting portion 1 and the latch 6, so that the latch 6 is pulled out of the insertion hole 501 of the filter 5, thereby releasing the fixation of the filter 5 and preparing for the subsequent removal of the filter 5.

[0108] After the latch 6 is pulled out, the filter screen 5 is no longer fixed.

[0109] At this time, the operator can rotate the lifting ring 502 on the top surface of the filter 5 to a position convenient for applying force, and then lift the lifting ring 502 upwards and use the fulcrum provided by the lifting ring 502 to lift the filter 5 upwards from the connecting part 1 along the sliding channel.

[0110] The lever opening 503 can provide a fulcrum for the staff when the staff needs to pull out the lifting ring 502, making it more convenient to pull out the lifting ring 502.

[0111] The pull ring on the latch 6 provides a convenient force application point for the operator, making the operation of pulling out the latch 6 more labor-saving and convenient, reducing the difficulty of disassembling the filter screen 5 and improving work efficiency.

[0112] The lifting ring 502 on the filter screen 5 also provides a good fulcrum point, which facilitates the removal of the filter screen 5 from the connecting portion 1 and avoids the inconvenience or damage that may be caused by directly grabbing the filter screen 5 by hand.
