Jacking mechanisms are particularly important in applications requiring precise height control, stable support, and heavy object handling.

[0003] Existing lifting mechanisms are primarily classified into mechanical, screw, hydraulic, pneumatic, and lever types, depending on their power source and transmission method. These mechanisms offer advantages such as simple structure, easy operation, and stability and reliability. As a crucial component of the extruder, the barrel can be categorized into various structural types, including integral, modular, and bimetallic. Integral barrels excel in precision, assembly, and thermal uniformity, while modular barrels facilitate adjustment of the screw aspect ratio to meet production needs.

When the combined barrel of the extruder is blocked or the internal extrusion screw fails and needs to be repaired during the extrusion process, the combined setting of the barrel facilitates the disassembly of the barrel. However, the existing combined barrel is not easy to quickly lift and separate the disassembled barrel parts, which makes it difficult to adapt to the use requirements of the barrel and affects the stable and reliable use of the extruder barrel.

DETAILED DESCRIPTION

[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0022] In this embodiment, refer to Figure 1-Figure 5The invention discloses a lifting mechanism for an extruder barrel, comprising a base plate 1 and a lifting assembly arranged on the base plate 1. The base plate 1 is provided with a driving motor 2 for driving the lifting assembly to perform lifting movements. The output end of the driving motor 2 is connected to a motor commutator 3. The two sides of the motor commutator 3 are symmetrically connected to a steering gear 4. A double-headed screw 5 is coaxially connected to one side of the steering gear 4. The two ends of the double-headed screw 5 are respectively formed with a forward-rotating end 6 and a reverse-rotating end 7. The forward-rotating end 6 and the reverse-rotating end 7 on the double-headed screw 5 are specifically left-handed and right-handed screw teeth, so that the two sliding seats 8 can be driven to move under the rotation of the double-headed screw 5.

[0023] The driving motor 2 is connected to the input end of the motor commutator 3 through the output shaft. The output ends are symmetrically arranged on both sides of the motor commutator 3, and the two sides of the motor commutator 3 are connected to the input end of the steering gear 4 through a coupling, so that the rotation of the driving motor 2 can drive the double-headed screw 5 to rotate.

[0024] There are two groups of jacking assemblies, and both groups of jacking assemblies include two horizontally arranged sliding seats 8, two cross-arranged jacking connecting rods 9 and a mounting top plate 11 for mounting the barrel base 10. The two sliding seats 8 are coaxially connected to the forward rotating end 6 and the reverse rotating end 7 of the double-headed screw 5, respectively, so that the two sliding seats 8 can approach or move away from each other along the axial direction of the double-headed screw 5 through the rotation of the double-headed screw 5. One end of the two jacking connecting rods 9 is respectively hinged to a sliding seat 8, and the other end of the two jacking connecting rods 9 is respectively hinged to one end of the mounting top plate 11, and the barrel base 10 is detachably mounted on the mounting top plate 11.

[0025] A guide rail 12 is provided on the base plate 1 , and a slidable slider 13 is provided on the guide rail 12 in pair. The sliding seat 8 is installed on the slider 13 and can slide along the length direction of the guide rail 12 through the slider 13 .

[0026] Specifically, the pairing of the slider 13 and the slide rail allows the sliding seat 8 to move precisely along the slide rail through the slider 13, thereby improving the lifting accuracy of the jacking mechanism and further improving the pairing and installation accuracy of the barrel base 10 and the extruder, thereby facilitating the combination of the barrel base 10.

[0027] The sliding seat 8 is coaxially connected to the double-headed screw 5 through a nut, and the sliding seat 8 is hinged to one end of the jacking link 9 through a pin, so that the jacking link 9 can rotate and swing along the pin, and a mounting seat 14 for connecting the other end of the jacking link 9 is provided on the mounting top plate 11.

[0028] Specifically, by cross-arranging the lifting rods 9, the ends of the two lifting rods 9 are driven by the sliding seat 8 to move closer to or farther away from each other. When the ends of the two lifting rods 9 are close to each other, the barrel base 10 can be driven to rise. Conversely, when the ends of the two lifting rods 9 are farther away from each other, the barrel base 10 can be driven to descend, thereby improving the rapid separation of the barrel base 10 and making it convenient to use.

[0029] Two lifting assemblies are symmetrically arranged on the base plate 1. A mounting flange 15 is formed on the side of the barrel base 10. The mounting top plate 11 abuts against the mounting flange 15 and is connected by bolts. A trough 19 for extruded material is formed inside the barrel base 10. The arrangement of the lifting assemblies enables the raising and lowering operations of the barrel base 10 to be carried out accurately and orderly, improving the convenience and stability of the combined connection between the barrel base 10 and the extruder.

[0030] A support base 16 is mounted on the base plate 1. A support guide rod 17 is coaxially connected to the interior of the support base 16. A bearing frame 18 is connected to the top of the support guide rod 17. A spring is sleeved on the support guide rod 17. Four support bases 16 are provided, located at the four corners of the barrel base 10. The number and position of the support guide rods 17 are matched to the support base 16, further enhancing the support and stability of the barrel base 10.

[0031] Specifically, when the lifting assembly descends, the barrel base 10 also descends onto the supporting frame 18 , so that the supporting frame 18 and the support seat 16 can support the barrel base 10 and improve the support stability of the barrel base 10 .

[0032] In this embodiment, a drive motor 2 is used as the power source. The design of the motor commutator 3 and the steering gear 4 enables the power output of the motor to be smoothly and flexibly transmitted to the double-headed screw 5, realizing the direction control and speed adjustment of power transmission, enhancing the flexibility and adaptability of the lifting mechanism, and meeting the needs of different working scenarios. The entire lifting mechanism achieves smooth, rapid, and precise lifting and lowering of the barrel base 10 through the coordinated action of various components, improving the assembly and connection efficiency and stability of the barrel base 10 in the extruder.

[0033] In this embodiment, the combined barrel is specifically configured as follows: the barrel is composed of a barrel base 10, two side plates and two end plates 20. The two end plates 20 are located at both ends of the barrel base 10, so that after the barrel base 10 rises, the material troughs 19 opened at both ends of the barrel base 10 form a sealed material trough 19 on all sides after the end plates 20 are connected at both ends.

[0034] The specific installation and use in this embodiment are as follows: the barrel base 10 is connected and installed with the mounting top plate 11 by bolts, so that the mounting top plate 11 provides a support platform for the barrel base 10, which facilitates the convenience and stability of the connection between the barrel base 10 and the mounting top plate 11. The barrel base 10 is detachably mounted on the mounting top plate 11, which is convenient for replacement and maintenance, and improves the flexibility of the use of the barrel base 10. The double-headed screw 5 can be driven to rotate by the driving motor 2, so that after passing through the motor commutator 3 and the steering gear 4, the double-headed screw 5 rotates, so that the positive rotation end 6 (left rotation) and the reverse rotation end 7 (right rotation) are connected and slid by the nut. The movable seat 8 realizes the two sliding seats 8 to move closer to or farther away from each other, thereby driving the lifting connecting rod 9 to rise or fall. The transmission efficiency is improved by setting the positive rotation end 6 and the counter-rotation end 7 of the double-headed screw 5, and the stability and balance of the barrel base 10 during the lifting process are improved, thereby facilitating the lifting and separation of the barrel base 10. The support seat 16 and the bearing frame 18 provided can support the descending barrel base 10, improve the stability and stability of use, thereby reducing the operational difficulty and labor cost of disassembling and separating the barrel base 10, making it convenient for the barrel base 10 to be used in combination in the extruder.
