Description

Technical Field

[0001] This application relates to the field of plastic processing equipment technology, and in particular to an ejection device for a distributor. Background Technology

[0002] Multilayer co-extrusion technology has been widely used in the production of plastic sheets. With the market's diversified demand for multifunctional composite materials, extrusion production lines need to frequently switch to produce products with different layer structures, such as ordinary ABA three-layer structure and two-color AB two-layer structure. This layer switching needs to be achieved by replacing the distributor. As the core component of the extruder, the distributor is heavy and requires high installation precision.

[0003] In related technologies, the distributor is mainly replaced manually. Operators need to use metal tools to manually pry the distributor off its installation position. This method is complicated and time-consuming.

[0004] The existing methods for replacing shunts have the following problems: they rely too much on worker skill and are inefficient. The industry is increasingly in need of rapid replacement of such heavy components, and there is an urgent need to develop specialized auxiliary equipment to improve production efficiency. Summary of the Invention

[0005] To improve production efficiency, this application provides an ejector device for a splitter.

[0006] The ejection device for a splitter provided in this application adopts the following technical solution: An ejection device for a distributor includes: a frame, an ejection assembly, and a hydraulic assembly. The frame includes a platform, and the ejection assembly and the hydraulic assembly are both mounted on the platform. The ejection assembly includes a push rod and a push block. The push block, the push rod, and the hydraulic assembly are arranged in the same direction and connected in sequence. The hydraulic assembly drives the push rod to extend, thereby moving the push block to assist manual replacement of the distributor.

[0007] By adopting the above scheme, after the hydraulic components are started, they push the push rod to move linearly, which causes the rigidly connected push block to generate axial displacement. The distributor is then smoothly pushed out of the installation position by mechanical jacking. The whole process is carried out under the stable support of the platform, which reduces the rigid requirement for skilled personnel to replace the distributor, shortens the replacement time, and indirectly improves production efficiency.

[0008] Preferably, the top block and the top rod are detachably connected, and when the top rod is extended, the top block abuts against the concave surface at the bottom of the distributor, and the shape of the top block is adapted to the concave surface at the bottom of the distributor.

[0009] By adopting the above technical solution, workers can replace the top blocks of different specifications to adapt to different distributors. After the top rod is extended, the top block makes full contact with the distributor, making the ejection process more stable. This helps workers to complete the replacement of the distributor more efficiently and safely, and also helps to reduce damage to the installation surface of the distributor caused by manual disassembly and assembly.

[0010] Preferably, the hydraulic assembly includes a hydraulic cylinder and a directional valve. The hydraulic cylinder is fixed on the frame, and the end of the push rod away from the top block is connected to the piston rod of the hydraulic cylinder and coaxially arranged. The directional valve is connected to the oil inlet of the hydraulic cylinder through an oil pipeline.

[0011] By adopting the above technical solution, when the directional valve is manually operated to switch the oil circuit direction, the hydraulic oil enters the hydraulic cylinder through the oil pipeline, driving the piston rod of the hydraulic rod to move linearly. The piston rod and the push rod are rigidly connected coaxially, which can convert the hydraulic pressure into the axial thrust of the push rod, pushing the push block to complete the diverter ejection operation.

[0012] Preferably, it also includes a guide sleeve, one end of the hydraulic cylinder is fixed inside the guide sleeve, and the bottom of the guide sleeve is provided with two legs, the bottom of the two legs being fixed to the upper surface of the platform.

[0013] By adopting the above scheme, the hydraulic cylinder serves as the power core to provide axial thrust, while the external guide sleeve constrains the movement trajectory of the hydraulic cylinder piston rod through its inner wall. The two legs and the platform form a triangular support structure, which improves the stability and axial accuracy of the hydraulic cylinder.

[0014] Preferably, the frame further includes support rods and a base, with at least two support rods, and the frame, support rods, and base are connected in sequence in the vertical direction.

[0015] By adopting the above scheme, the reasonable structural layout of the platform, support rods and base forms multi-point support, establishes a force transmission path between the ejection component and the ground, and provides a stable support foundation for the ejection operation of the device.

[0016] Preferably, the bottom of the frame is provided with pulleys, and the pulleys abut against the ground.

[0017] By adopting the above scheme, the overall structure of the equipment is made capable of translation, which makes it easy for workers to push the equipment to adjust the ejection position, thus combining mobility and convenience.

[0018] Preferably, a retaining ring is provided on the pulley.

[0019] By adopting the above scheme, the snap ring uses the combined effect of mechanical constraint and elastic deformation to brake the pulley. After the pulley is locked, it remains relatively stationary with respect to the ground and still has the support strength required for movement.

[0020] Preferably, it further includes reinforcing ribs, which are arranged in an X-shape between the support rods, and the upper and lower ends of the reinforcing ribs are fixed to the connection points of the support rods and the frame, and the connection points of the support rods and the frame base, respectively.

[0021] By adopting the above scheme, the two ends of the rib plate are fixed to the connection points of the support rod, the frame, and the base, forming multiple triangular structural units. Their cross-layout can effectively disperse lateral loads and improve the overall vibration resistance and dynamic stability of the equipment.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. After the hydraulic components are started, they push the push rod to move linearly, which causes the rigidly connected push block to produce axial displacement. The distributor is smoothly pushed out of the installation position by mechanical pushing, which reduces the need for skilled personnel to replace the distributor, shortens the replacement time, and indirectly improves production efficiency. 2. Reduces damage to the splitter mounting surface caused by manual disassembly and assembly; 3. Improved the convenience and stability of the equipment. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0027] This application discloses an ejector device for a splitter. (Refer to...) Figure 1-2 An ejection device for a splitter includes a frame 1, an ejection assembly 2, and a hydraulic assembly 3. The frame 1 includes a platform 11, and the ejection assembly 2 and the hydraulic assembly 3 are both mounted on the platform 11.

[0028] Furthermore, the ejector assembly 2 includes an ejector rod 21 and an ejector block 22. The ejector block 22, ejector rod 21, and hydraulic assembly 3 are arranged in the same direction and connected in sequence. The hydraulic assembly 3 drives the ejector rod 21 to extend, thereby driving the ejector block 22 to assist in the manual replacement of the distributor.

[0029] Therefore, after the hydraulic component 3 is started, it pushes the push rod 21 to move linearly, which drives the rigidly connected push block 22 to generate axial displacement. The distributor is smoothly pushed out of the installation position by mechanical pushing. The whole process is carried out under the stable support of the stand 11, which reduces the rigid requirement for manual replacement of the distributor, shortens the replacement time, and indirectly improves production efficiency.

[0030] In the process described above, the top block 22 and the top rod 21 are detachably connected. The shape of the top block 22 is adapted to the concave surface at the bottom of the distributor. After the top rod 21 is extended, the top block 22 abuts against the concave surface at the bottom of the distributor.

[0031] Therefore, staff can replace the top block 22 of different specifications to adapt to different distributors, achieving "one rod for multiple uses". When the top rod 21 extends, it drives the corresponding top block 22 to precisely fit the concave contour of the bottom of the distributor, forming a surface contact support. The pressure distribution on the contact surface is uniform, which not only improves the replacement efficiency, but also reduces the occurrence of scratches on the equipment installation surface caused by human operation, and reduces the safety risk of too many people working in narrow spaces.

[0032] On the other hand, the hydraulic assembly 3 includes a hydraulic cylinder 31 and a reversing valve 32. The hydraulic cylinder 31 is fixed on the frame 11. The end of the push rod 21 away from the top block 22 is connected to the piston rod of the hydraulic cylinder 31 and is coaxially arranged. The reversing valve 32 is connected to the oil inlet of the hydraulic cylinder 31 through an oil pipeline to form a control oil circuit, thereby realizing the control of the extension and retraction of the piston rod of the hydraulic cylinder 31.

[0033] Correspondingly, when the directional valve 32 is manually operated to switch the oil circuit direction, the hydraulic oil enters the hydraulic cylinder 31 through the oil pipeline, driving the piston rod of the hydraulic rod to produce linear motion. Since the piston rod and the push rod 21 are rigidly connected coaxially, the pressure of the hydraulic cylinder 31 can be directly converted into the axial mechanical thrust of the push rod 21, and finally the distributor is smoothly pushed out through the matching push block 22.

[0034] In addition, the hydraulic assembly 3 also includes a guide sleeve 33, one end of the hydraulic cylinder 31 is fixed inside the guide sleeve 33, and two legs 34 are welded to the bottom of the guide sleeve 33. The bottom of the two legs 34 is fixed to the upper surface of the platform 11.

[0035] Therefore, the split support design of the bipod 34, together with the platform 11, forms a triangular stable support structure, which can evenly transmit the vibration generated by hydraulic impact to the platform 11, forming a stable torque balance system. The guide sleeve 33 provides axial positioning for the hydraulic cylinder 31, improving the linear accuracy of the piston rod movement trajectory. When the push rod 21 is ejected, the power transmission path is always kept in a centered state under the physical constraint of the inner wall of the guide sleeve 33, reducing equipment wear caused by off-center load.

[0036] On the other hand, the frame 1 also includes support rods 12 and bases 13. In this embodiment, both the support rods 11 and the bases 13 are rectangular in shape. There are four support rods 12 in total. The support rods 11 are welded to the top of the support rods 12, and the bases 13 are welded to the bottom of the support rods 12.

[0037] Therefore, the frame 13 serves as the ground anchor point, the support rod 12 forms a rigid force transmission skeleton, and the platform 11 serves as the installation platform for other components. Together, the three form a stable spatial force transmission network, which evenly disperses the reaction force generated during the jacking operation, effectively reducing structural vibration and displacement during the operation. While ensuring efficient transmission of jacking force, this support system also improves the structural stability of the equipment under dynamic load through multi-node constraints.

[0038] Meanwhile, the frame 1 is also provided with reinforcing ribs 14, which are X-shaped and cross-welded between the support rods 12. The welding points at the upper and lower ends of the reinforcing ribs 14 coincide with the welding points of the support rods 12 and the frame 11, as well as the welding points of the support rods 12 and the frame 13.

[0039] Therefore, the reinforcing rib 14 connects the key nodes of the support rod 12, the platform 11, and the base 13 in the form of a spatial truss. Through the cross structure, multiple triangular structural units are formed to build a continuous force transmission path, decomposing the lateral load into axial force along the diagonal direction of the reinforcing rib 14, thereby improving the overall vibration resistance and dynamic stability of the equipment.

[0040] In addition, a pulley 121 is provided at the bottom of the frame 13. The pulley 121 abuts against the ground. A retaining spring 122 is provided on the pulley 121. The pulley 121 gives the equipment omnidirectional movement capability, allowing workers to easily push the equipment to adjust the work position. The matching retaining spring 122 brakes the pulley 121 through the elastic locking principle. After the pulley 121 is locked, it remains relatively stationary with respect to the ground, and the device still has the support strength in the moving state.

[0041] Furthermore, the pulley 121-spring clip 122 composite mechanism supports the equipment to perform dual-mode switching of "movement-locking". In the moving state, the equipment maintains low-friction rolling, while in the locked state, the deformation pressure of the spring clip 122 causes the pulley 121 to form static friction braking with the ground, thus making the equipment both convenient and stable.

[0042] The implementation principle of the ejection device for a distributor in this embodiment is as follows: The operator first installs a hook on the gantry at the top of the distributor, hooks the distributor with the hook, and then starts the hydraulic cylinder 31 to drive the piston rod to push the push rod 21 to move linearly, so that the top block 22 at the top of the push rod 21 generates axial displacement and pushes the distributor out smoothly from the installation position by mechanical pushing. The ejection operation is carried out under the stable support of the frame 11, which reduces the rigid requirement for manual replacement of the distributor, shortens the replacement time, and indirectly improves production efficiency.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
