Description

Technical Field

[0001] This invention belongs to the field of ultra-high pressure equipment, and specifically relates to a material unloading structure. Background Technology

[0002] When processing raw materials such as food, ultra-high pressure equipment requires frequent feeding and discharging of the material cylinder. Since the material cylinders of ultra-high pressure equipment are generally quite heavy, a specialized unloading mechanism is necessary. Existing unloading mechanisms come in various forms; for example, the applicant filed a patent application in 2021 with application number CN202122507201.9, entitled: "A Utility Model of an Unloading Mechanism and an Ultra-High Pressure Equipment Using the Unloading Mechanism."

[0003] Most existing unloading mechanisms are single-function, only capable of emptying the material cylinder. The transfer of the cylinder between the discharge and return racks still relies on manual handling, which is time-consuming and labor-intensive, affecting the overall rotation efficiency of the cylinder. Some manufacturers use robotic arms to improve efficiency, which saves labor and increases efficiency, but the overall cost is high. Summary of the Invention

[0004] This invention addresses the problems existing in the prior art by proposing a material unloading structure. The unloading mechanism of this invention combines the functions of material pouring and material cylinder transfer. After material pouring is completed, the material cylinder can automatically flip from the discharge rack to the return rack, shortening the entire rotation cycle of the material cylinder, improving efficiency, and saving time and labor.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a discharge structure, including a discharge base frame hinged to a discharge mechanism, a drive mechanism provided below the discharge base frame, the drive mechanism pushing the discharge base frame to rotate around the hinge, a discharge bracket provided above the discharge base frame, the discharge bracket being connected to the discharge base frame via a side-mounted flip hinge, a support plate provided on the opposite side of the flip hinge, one end of the support plate being hinged to the discharge bracket, and a sliding wheel provided at the other end of the support plate, and a limit mechanism installed on the same plane as the discharge bracket and the support plate.

[0006] Furthermore, the unloading support includes a central frame, with multiple sets of inclined frames symmetrically arranged on both sides of the central frame. Rollers are installed at the free ends of the inclined frames, and a material cylinder support plate is provided at the tail of the central frame. Two lifting lugs are spaced apart on one side of the central frame, and a tray mounting seat is provided on the other side.

[0007] Furthermore, the unloading base includes a support plate, and L-shaped connecting plates are fixedly installed at both ends of the support plate. One end of the L-shaped connecting plate is fixedly connected to the support plate, and the other end of the L-shaped connecting plate is hinged to the lifting lug.

[0008] Furthermore, a shock-absorbing pad is fixedly installed on the upper surface of the support plate.

[0009] Furthermore, the limiting mechanism includes a vertical plate, which is fixedly installed on the lower surface of the central frame and the center of the vertical plate is on the same horizontal plane as the center of the pallet mounting seat. A limiting bolt is provided on the vertical plate, with the bolt head of the limiting bolt facing the pallet side.

[0010] Furthermore, the drive mechanism is a pneumatic cylinder or a hydraulic cylinder.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the unloading frame of the unloading mechanism is divided into an unloading support and an unloading base frame. Hinges are installed on the sides of the unloading support and the unloading base frame, allowing the unloading support to rotate relative to the unloading base frame. Simultaneously, a drive mechanism acts on the unloading base frame, causing the unloading support to tilt and unload material together. After unloading is completed, the unloading support uses a pallet and a limiting mechanism to automatically transfer the material cylinder and reset the unloading support.

[0012] The unloading structure of this invention does not require additional power during the process of the material cylinder flipping from the discharge rack to the return rack. It automatically completes the flipping using a pallet and pulley, saving time and effort and improving the rotation efficiency of the material cylinder. Attached Figure Description

Detailed Implementation

[0023] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand how the present invention uses technical means to solve technical problems and achieve technical effects and to implement it accordingly.

[0024] like Figures 1-3 As shown, a discharge structure includes a discharge base frame 2 hinged to a discharge mechanism 1. The discharge base frame 2 serves as both the connector between the entire discharge mechanism and the discharge mechanism 1 and a support component for other parts of the discharge mechanism. A drive mechanism 3 is disposed below the discharge base frame 2. The drive mechanism 3 can be a pneumatic cylinder or a hydraulic cylinder, depending on the requirements. The purpose of the drive mechanism 3 is to push the discharge base frame 2 to rotate along the direction of the discharge mechanism 1. During the rotation process, the discharge base frame 2 will cause other components on the discharge base frame 2 and the material cylinder to rotate as well, thereby completing the material cylinder discharge process.

[0025] An unloading bracket 4 is provided above the unloading base frame 2. The unloading base frame 2 and the unloading bracket 4 are connected by a flip hinge 5 provided on the side. In this way, the unloading bracket 4 can be flipped around the flip hinge 5. A support plate 6 is provided on the other side opposite to the flip hinge 5. One end of the support plate 6 is hinged to the unloading bracket 4, and the other end of the support plate 6 is provided with a sliding wheel 7. A limit mechanism 8 is installed on the same plane as the unloading bracket 4 and the support plate 6.

[0026] like Figures 6-9 As shown, the process of the material cylinder flipping of the unloading mechanism of the present invention is as follows: During the rotation of the unloading bracket 4, the center of the sliding wheel 7 will be offset to the left of the center of the hinge point between the sliding wheel 7 and the plate 6 and the unloading bracket 4 due to the influence of gravity. This state is maintained until the unloading bracket 4 descends to the point where the sliding wheel 7 contacts the discharge mechanism 1. Figure 6 The offset of the sliding wheel 7 can be adjusted as needed by changing the structure of the support plate 6 or by adding or removing counterweights on the right side of the support plate 6.

[0027] Then the unloading base frame 2 continues to descend, and the sliding wheel 7 slides to the left (in the direction shown in the figure) until the pallet 6 hits the limiting mechanism 8, preventing the pallet 6 from sliding further to the left (in the direction shown in the figure). Figure 7At this time, the unloading bracket 4 is unable to continue to descend with the unloading base frame 2 because the support plate 6 is blocked by the limit. It is supported by the support plate 6 and rotates around the hinge. The support plate 6 also rotates, causing the sliding wheel 7 to slide to the right relative to the unloading bracket.

[0028] As the unloading bracket 4 flips over until the center of gravity of the material cylinder passes the support point of the idler roller, the material cylinder rolls down. At this time, the unloading base frame 2 descends to the bottom or is still in the process of descending, and the center of the sliding wheel 7 passes the center of the hinge point of the unloading bracket 4. Figure 8 Under the pressure of the unloading bracket 4, it continues to slide to the right and disengage from the limit screw, no longer supporting the unloading bracket 4. Finally, the unloading bracket 4 flips over and falls back onto the unloading base frame 2. Figure 9 】

[0029] The principle and specific process of the tilting cylinder of the present invention have been described in detail above. However, the specific structure and connection method of the unloading bracket 4, the unloading base frame 2, and the limiting mechanism 8 have not been specified in detail. In order to facilitate those skilled in the art to better understand the present invention, based on the above embodiments, these components and their connection relationships are described in detail in this embodiment.

[0030] like Figure 4 As shown, the unloading support 4 includes a middle frame 41, with multiple sets of inclined frames 42 symmetrically arranged on both sides of the middle frame 41. Rollers 43 are installed at the free ends of the inclined frames 42. A material cylinder support plate 44 is provided at the tail of the middle frame 41. The rollers 43 and the material cylinder support plate 44 cooperate with each other to support the material cylinder. Two lifting lugs 45 are provided at intervals on one side of the middle frame 41. The lifting lugs 45 are used to hinge with the L-shaped connecting plate 22 of the unloading base frame 2. A tray mounting seat 46 is provided on the other side.

[0031] like Figure 5 As shown, the unloading base frame 2 includes a support plate 21. L-shaped connecting plates 22 are fixedly installed at both ends of the support plate 21. One end of the L-shaped connecting plate 22 is fixedly connected to the support plate 21, and the other end is hinged to the lifting lug 45. Since the unloading base frame 2 and the unloading bracket 4 need to come into frequent contact during the unloading process, a shock-absorbing pad 23 is fixedly installed on the upper surface of the support plate 21. The presence of the shock-absorbing pad 23 can prevent rigid collisions between the two, extend their service life, and reduce noise.

[0032] The limiting mechanism 8 includes a vertical plate 81, which is fixedly mounted on the lower surface of the central frame 41 and is at the same horizontal plane as the center of the support plate mounting base 46. A limiting bolt 82 is provided on the vertical plate 81, with the bolt head of the limiting bolt 82 facing the support plate 6. The support plate 6 is limited after colliding with the bolt head.

[0033] In use, the unloading structure of this invention is typically installed at the tail of the discharge mechanism 1. Existing return mechanisms are generally arranged side-by-side with the discharge mechanism 1, with a transport frame between them. With the help of the unloading structure of this invention, automatic transfer of the material cylinder can be achieved. This invention divides the unloading frame of the unloading mechanism into an unloading support 4 and an unloading base 2. Hinges are installed on the sides of the unloading support 4 and the unloading base 2, allowing the unloading support 4 to rotate relative to the unloading base 2. Simultaneously, the drive mechanism 3 acts on the unloading base 2, causing the unloading support 4 to tilt and discharge material. This achieves both unloading and transport of the material cylinder from the discharge mechanism 1 to the return mechanism.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
