Description

Technical Field

[0001] This utility model relates to the field of pressing equipment technology, specifically a pressing machine that is easy to use. Background Technology

[0002] In industrial production, many fields require the extrusion of materials. As a commonly used piece of equipment, the material press is used to compress materials into specific shapes or increase their density.

[0003] Sealing is a major challenge for traditional material presses. In applications involving high pressure, high viscosity, and high frequency operation, materials generate high pressure during extrusion, and high-viscosity materials tend to adhere to equipment components, increasing the risk of leakage. Traditional material presses typically have simple sealing structures, usually using only a single sealing ring. However, under high pressure and complex operating conditions, a single sealing ring is prone to wear and aging, leading to seal failure. Leakage not only wastes material but can also pollute the surrounding environment. Therefore, a user-friendly material press is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-use pressing machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a material pressing machine that is easy to use, including a frame, a material barrel fixed on one side of the frame, a pressure plate inside the material barrel, and a plurality of first sealing rings and second sealing rings installed on the outside of the pressure plate through grooves, the first sealing rings and second sealing rings being used to seal the gap between the material barrel and the pressure plate;

[0006] A connecting plate is fixed to the top of the material barrel, and two cover plates are hinged to the top of the connecting plate;

[0007] A hydraulic cylinder is provided on the top of the cover plate, and a connecting component is provided on one side of the cover plate;

[0008] The connecting component includes a limiting frame and a connecting block. The limiting frame has a limiting groove and a sliding groove on its inner side, and a sliding plate is slidably connected to the inner side of the sliding groove.

[0009] A limit rod is fixed on one side of the connecting block, and a locking groove is provided on one side of the limit rod.

[0010] Preferably, the first sealing ring has a circular cross-section, and the second sealing ring has a V-shaped cross-section.

[0011] Preferably, as described above, a fixing frame is fixed to the top of the frame, the hydraulic cylinder is fixed to the top of the fixing frame, and the push rod end of the hydraulic cylinder is fixed to the top of the pressure plate.

[0012] Preferably, the bottom center of the material hopper is connected to a three-way pipe, a discharge pipe is provided on one side of the bottom of the three-way pipe, and a feed pipe is provided on the other side of the bottom of the three-way pipe. Valves are installed on both the discharge pipe and the feed pipe.

[0013] Preferably, the bottom of the slide plate is fixed with a locking rod. When the locking rod is inserted into the locking groove, the two cover plates are in a closed state. When the locking rod leaves the locking groove, the two cover plates are in an open state.

[0014] Preferably, as described above, a spring connects the slide and the slide plate, and a baffle located on the side of the spring is bolted to one side of the limiting frame.

[0015] Preferably, as described above, a pull rod is fixed to the top of the skateboard, and the outer side of the pull rod extends through the top of the limiting frame.

[0016] Preferably, the limiting frame and the connecting block are fixed to one side of the cover plate, and the outer side of the limiting rod is adapted to the inner side of the limiting groove.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0018] 1. The hydraulic cylinder push rod moves downward, which in turn drives the pressure plate to move downward inside the material barrel to apply uniform pressure to the material, so that the material is effectively squeezed. Several first and second sealing rings are installed on the outside of the pressure plate through grooves. Multiple sealing rings form a reliable high-pressure sealing barrier to ensure that the medium does not leak under high pressure. This ensures the sealing safety of the equipment in high-pressure, high-viscosity, and high-frequency operation scenarios, enabling the equipment to operate stably under various complex and harsh working conditions.

[0019] 2. When it is necessary to open the cover plate, simply pull the lever upwards to move the locking rod away from the locking groove, releasing the locking state of the two cover plates. Then, the cover plate can be easily pushed to rotate around the hinge point to open, facilitating maintenance of the first or second sealing ring on the outside of the pressure plate, reducing maintenance difficulty and time costs. When the two cover plates are pushed close together, the limit rod enters the limit groove. After releasing the lever, the lever drives the slide plate and locking rod downwards, and the locking rod inserts into the inner side of the locking groove, realizing a stable lock on the two cover plates, preventing the cover plates from opening accidentally during operation, and ensuring the safety and stability of equipment operation.

[0029] Example

[0030] Please see Figure 1-5 This utility model provides a technical solution: a material pressing machine that is easy to use, including a frame 1, a material barrel 4 fixed on one side of the frame 1, the frame 1 as the main frame, the fixed material barrel 4 provides overall structural support, a pressure plate 10 is provided inside the material barrel 4, and a plurality of first sealing rings 12 and second sealing rings 13 are installed on the outside of the pressure plate 10 through grooves. The first sealing rings 12 and second sealing rings 13 are used to seal the gap between the material barrel 4 and the pressure plate 10. The pressure plate 10 moves up and down inside the material barrel 4 to apply uniform pressure to the material inside the material barrel 4.

[0031] A connecting plate 9 is fixed to the top of the material bucket 4. Two cover plates 3 are hinged to the top of the connecting plate 9. A sealing strip is provided between the cover plates 3. The outer side of the push rod of the hydraulic cylinder 8 is slidably connected to one side of the sealing strip. A hydraulic cylinder 8 is provided on the top of the cover plate 3. A connecting component 2 is provided on one side of the cover plate 3.

[0032] The first sealing ring 12 has a circular cross-section, and the second sealing ring 13 has a V-shaped cross-section. The second sealing ring 13 can be a V-shaped oil seal. Multiple first sealing rings 12 and second sealing rings 13 form a reliable high-pressure sealing barrier to ensure that the medium does not leak under high pressure. A fixed frame 7 is fixed on the top of the frame 1, and the hydraulic cylinder 8 is fixed on the top of the fixed frame 7. The oil inlet and outlet of the hydraulic cylinder 8 are connected to the hydraulic station. The push rod end of the hydraulic cylinder 8 passes through the center of the cover plate 3. The hydraulic cylinder 8 is installed on the top of the frame 1 through the fixed frame 7. Its push rod passes through the center of the cover plate 3 and is connected to the pressure plate 10. The oil inlet and outlet of the hydraulic cylinder 8 are connected to the hydraulic station. The piston movement drives the pressure plate 10 to rise and fall vertically in the material barrel 4, applying uniform pressure to the material. The push rod end of the hydraulic cylinder 8 is fixed on the top of the pressure plate 10.

[0033] A three-way pipe 15 is connected to the center of the bottom of the material barrel 4. A discharge pipe 5 is provided on one side of the bottom of the three-way pipe 15, and a feed pipe 6 is provided on the other side of the bottom of the three-way pipe 15. Valves are installed on both the discharge pipe 5 and the feed pipe 6. The discharge pipe 5 is connected to the downstream discharge mechanism to achieve uniform feeding under pressure. The feed pipe 6 is connected to the upstream feeding system to achieve continuous material input or batch feeding. The pressurized material is continuously or intermittently output from the discharge pipe 5 in the center of the material barrel 4 to achieve stable feeding and process pressure balance. Multiple sealing rings ensure the overall equipment sealing safety and are suitable for high pressure, high viscosity, high frequency operation and other application scenarios.

[0034] The connecting assembly 2 includes a limiting frame 21 and a connecting block 25. The limiting frame 21 has a limiting groove 22 and a sliding groove 27 on its inner side. The width of the limiting groove 22 is greater than the width of the limiting rod 24, allowing the rotating limiting rod 24 to easily insert into the limiting groove 22. A sliding plate 26 is slidably connected to the inner side of the sliding groove 27. The connecting block 25 has a limiting rod 24 fixed to one side, and a locking groove 23 is provided on one side of the limiting rod 24. The diameter of the locking groove 23 is greater than the diameter of the locking rod 210, facilitating the locking of the rod 210. With the insertion of the locking rod 210 fixed at the bottom of the slide plate 26, when the locking rod 210 is inserted into the inner side of the locking groove 23, the two cover plates 3 are in a closed state. When the locking rod 210 leaves the inner side of the locking groove 23, the two cover plates 3 are in an open state. When the two cover plates 3 are closed, the limiting rod 24 of the connecting block 25 is inserted into the limiting groove 22 of the limiting frame 21. Under the action of the spring 28, the slide plate 26 moves down along the slide groove 27, which drives the locking rod 210 to be engaged in the locking groove 23 of the limiting rod 24, thus locking the cover plate 3.

[0035] A spring 28 is connected between the slide 27 and the slide plate 26. A baffle 11 located on the side of the spring 28 is bolted to one side of the limit frame 21. A pull rod 29 is fixed to the top of the slide plate 26. Pulling the pull rod 29 upwards compresses the spring 28 of the slide plate 26 and moves it upwards. The locking rod 210 disengages from the locking groove 23, and the cover plate 3 rotates and unfolds around the hinge point for easy maintenance. When the sealing ring needs maintenance, the cover plate 3 is opened first, and the pressure plate 10 is raised away from the inside of the material barrel 4 by the push rod end of the control hydraulic cylinder 8.

[0036] The outer side of the pull rod 29 extends through the top of the limiting frame 21. The limiting frame 21 and the connecting block 25 are respectively fixed to one side of the cover plate 3. The outer side of the limiting rod 24 is adapted to the inner side of the limiting groove 22.

[0037] Working principle: When the hydraulic station is started, hydraulic oil enters the oil inlet of hydraulic cylinder 8, pushing the push rod of hydraulic cylinder 8 downward. Since the push rod of hydraulic cylinder 8 passes through the center of cover plate 3, and cover plate 3 is hinged to the top of connecting plate 9, and connecting plate 9 is fixed to the top of material barrel 4, the push rod of hydraulic cylinder 8 pushes pressure plate 10 to move downward inside material barrel 4. During the downward movement of pressure plate 10, it applies uniform pressure to the material in material barrel 4, causing the material to be squeezed. When it is necessary to stop pressing, hydraulic oil flows out from the oil outlet of hydraulic cylinder 8 and returns to the hydraulic station. The push rod of hydraulic cylinder 8 retracts upward, driving pressure plate 10 to move upward and reset.

[0038] Several first sealing rings 12 and second sealing rings 13 are installed on the outer side of the pressure plate 10 through grooves. The first sealing ring 12 has a circular cross-section, and the second sealing ring 13 has a V-shaped cross-section. When the pressure plate 10 moves up and down in the material barrel 4, the first sealing rings 12 and second sealing rings 13 are in close contact with the inner wall of the material barrel 4. Multiple first sealing rings 12 and second sealing rings 13 form a reliable high-pressure sealing barrier to ensure that the medium does not leak under high pressure and to ensure the sealing safety of the equipment in high-pressure, high-viscosity, and high-frequency operation application scenarios.

[0039] When it is necessary to open the cover plate 3, pull the lever 29 upward. The lever 29 drives the slide plate 26 to slide upward in the slide groove 27. The spring 28 assists the slide plate 26 to move upward under its own elastic force. The slide plate 26 drives the locking lever 210 to move upward. When the locking lever 210 leaves the inside of the locking groove 23, the locking state of the two cover plates 3 is released. At this time, the two cover plates 3 can be pushed to rotate around the hinge point, so that the two cover plates 3 move away from each other, thereby opening the cover plate 3, thereby maintaining the first sealing ring 12 or the second sealing ring 13 on the outside of the pressure plate 10. The limit bracket 21 is connected to the baffle 11 by bolts on one side. The baffle 11 can be removed to maintain the spring 28.

[0040] The two cover plates 3 are rotated around the hinge point, bringing them closer together. At this time, the limiting bracket 21 and the connecting block 25 are fixed to one side of the two cover plates 3 respectively, and the outer side of the limiting rod 24 is adapted to the inner side of the limiting groove 22. As the cover plates 3 close, the limiting rod 24 enters the limiting groove 22, releasing the pulling rod 29. The pulling rod 29 drives the slide plate 26 to slide downward in the slide groove 27, and the locking rod 210 fixed at the bottom of the slide plate 26 moves downward accordingly. When the locking rod 210 is inserted into the locking groove 23 opened on one side of the limiting rod 24, the two cover plates 3 are locked and in a closed state. During this process, the spring 28 connecting the slide groove 27 and the slide plate 26 is compressed.

[0041] The feed pipe 6 is connected to the upstream feeding system. Opening the valve on the feed pipe 6 allows the upstream feeding system to continuously or batch-feed material into the material bin 4 through the feed pipe 6. The discharge pipe 5 is connected to the downstream discharge mechanism. When the pressure plate 10 applies pressure to the material in the material bin 4, the pressurized material is continuously or intermittently discharged from the discharge pipe 5 at the center of the bottom of the material bin 4, achieving stable material supply and process pressure balance. The valves on the discharge pipe 5 and the feed pipe 6 can control the flow rate and opening / closing of the material.

[0042] In summary, the downward movement of the push rod of the hydraulic cylinder 8 drives the pressure plate 10 to move downward inside the material barrel 4, applying uniform pressure to the material and effectively squeezing it. Several first sealing rings 12 and second sealing rings 13 are installed on the outer side of the pressure plate 10 through grooves. The multiple sealing rings form a reliable high-pressure sealing barrier, ensuring that the medium does not leak under high pressure. This ensures the sealing safety of the equipment in high-pressure, high-viscosity, and high-frequency operation scenarios, enabling the equipment to operate stably under various complex and harsh working conditions.

[0043] When it is necessary to open the cover plate 3, simply pull the lever 29 upwards to move the locking lever 210 away from the locking groove 23, releasing the locking state of the two cover plates 3. Then, the cover plate 3 can be easily pushed to rotate around the hinge point to open, facilitating maintenance operations on the first sealing ring 12 or the second sealing ring 13 on the outside of the pressure plate 10, reducing maintenance difficulty and time costs. When the two cover plates 3 are pushed close together, the limiting lever 24 enters the limiting groove 22. After releasing the lever 29, the lever 29 drives the sliding plate 26 and the locking lever 210 to move downwards, and the locking lever 210 inserts into the inside of the locking groove 23, achieving a stable lock on the two cover plates 3, preventing the cover plates 3 from being accidentally opened during operation, and ensuring the safety and stability of the equipment operation.
