Description

Technical Field

[0001] This utility model relates to the field of automated equipment technology, specifically to a pressure hopper assembly. Background Technology

[0002] Currently, the main methods for compressing metal scrap are through pneumatic or hydraulic cylinders, and another method is roller compression. The first method typically uses a pneumatic cylinder to directly compress and eject the scrap in one pass. Since the cylinder generates power and movement by controlling the intake and exhaust of compressed air, this method is limited in its effectiveness against hard, rigid metal scrap. Furthermore, during compression, the scrap may cause the piston in the cylinder to seize, affecting its normal operation. For hydraulic cylinder compression, due to the varying shapes, sizes, and hardness of metal scrap, it is also difficult to achieve ideal compression results. For example, the scrap may not be compressed evenly, or the density of the compressed scrap may not be high enough, both of which will affect subsequent processing and recycling. The second method, roller compression, is prone to problems because metal scrap easily becomes entangled in the rollers, causing them to jam and potentially malfunction during rotation.

[0003] Furthermore, the extrusion methods in the above-mentioned existing technologies can only achieve one compression and one push after one feeding. If the amount of material fed at one time is insufficient, it will result in insufficient material for one compression, and it is impossible to add material midway, which affects the extrusion efficiency. Utility Model Content

[0004] This utility model aims to overcome at least one of the defects of the prior art and provides a pressing chamber assembly that uses multiple hydraulic cylinders to quickly form a sealed mold cavity. It can realize multiple initial pressings and multiple feedings according to the feeding amount after feeding, for subsequent extrusion molding, thereby improving extrusion efficiency.

[0005] This utility model provides a pressing chamber assembly, including a pressing chamber body, a movable cover plate, and a drive assembly. The pressing chamber body has a feed inlet at its top and a pressing chamber inside. The drive assembly includes a first drive module and a second drive module. The movable cover plate includes a first pressure plate and a second pressure plate. One end of the first pressure plate is rotatably connected to one side of the pressing chamber body, and the other end is rotatably connected to the second pressure plate. The first drive module is used to drive the first pressure plate to rotate 90° relative to the pressing chamber body to achieve primary pressing of the pressing chamber. The second drive module is used to drive the second pressure plate to continue rotating 90° toward the pressing chamber to achieve secondary pressing of the pressing chamber.

[0006] The main body of the pressing chamber of this utility model has a square-like structure. In the open state, the first pressing plate and the second pressing plate are on the same horizontal plane. After material is fed into the inlet, when the first driving module drives the first pressing plate to rotate 90° relative to the pressing chamber body, the first and second pressing plates cover the inlet, realizing the first pressing of the material in the pressing chamber. If there is a lot of empty space in the pressing chamber at this time, the first driving module opens the first pressing plate, and the inlet is open, allowing for secondary feeding. Based on this utility model, a sensor or corresponding scale can be set in the pressing chamber. When the warning line is reached after pressing, feeding will stop. Then, the second driving module drives the second pressing plate to rotate another 90° toward the pressing chamber, realizing the secondary pressing of the pressing chamber. At this time, the first and second pressing plates are at 90°, so that the first pressing plate, the second pressing plate, and the inner wall of the pressing chamber body form a rectangular hexahedral sealed cavity. One end of the main body of the pressing chamber is connected to an external hydraulic cylinder. The external hydraulic cylinder extrudes and shapes the material into a sealed mold cavity before ejecting it. Finally, the material is processed and recycled.

[0007] The core invention of this invention is that it uses multiple hydraulic cylinders in linkage to quickly form a sealed mold cavity, which improves the extrusion efficiency. Furthermore, multiple feedings can be achieved through primary initial pressure, and the metal compressed block obtained by the final extrusion and pushing has a higher density, which further compresses the space of the finished product and improves the compression efficiency.

[0008] Preferably, the first drive module and / or the second drive module includes one or more sets of hydraulic cylinder drive components.

[0009] More preferably, the first drive module and the second drive module each include two sets of hydraulic cylinder drive components.

[0010] Furthermore, the main body of the pressure chamber is provided with a first hinge component, the first pressure plate and the first drive module are respectively fixed to the first hinge component, and the first drive module drives the first hinge component to rotate so as to drive the first pressure plate to rotate.

[0011] One end of the two sets of hydraulic cylinders of the first drive module is fixed to the main body of the pressure chamber; the other end is connected to the first hinge; the rotating end of the first hinge is connected to the first pressure plate; the rotating end of the first hinge is driven to rotate by the two sets of hydraulic cylinders of the first drive module, and the first pressure plate drives the second pressure plate to rotate synchronously toward the feed port to a horizontal state.

[0012] Furthermore, the pressing chamber assembly of this utility model also includes a second hinge component, and the first pressing plate and the second pressing plate are connected by the second hinge component; one end of the second drive module is fixed to the pressing chamber body, and the other end is connected to the second hinge component.

[0013] The second hinge component is designed to enable the second pressure plate to rotate relative to the first pressure plate. One end of the second hinge component is fixed to the first pressure plate, and the rotating end of the other end is connected to the second pressure plate. One end of the two sets of hydraulic cylinders of the second drive module is fixed to the first hinge component, and the other end is connected to the rotating end of the second hinge component. The two sets of hydraulic cylinders of the second drive module are used to realize the rotation of the rotating end of the second hinge component, thereby driving the second pressure plate to rotate.

[0014] More preferably, the two sets of hydraulic cylinder drive components of the second drive module are located between the two sets of hydraulic cylinder drive components of the first drive module. The overall volume is smaller, and they are symmetrical in pairs, resulting in more uniform force distribution and higher stability during the push-pull process.

[0015] Furthermore, the pressing chamber of the pressing hopper body is formed by a bottom plate, a first side plate, a second side plate, a third side plate, and a fourth side plate; the first drive module and the second drive module are located on the outside of the fourth side plate; the first side plate is provided with a first movable hopper door, and the third side plate is provided with a second movable hopper door symmetrical to the first movable hopper door.

[0016] The pressing chamber of this utility model is an approximately rectangular cavity. The first movable chamber door of the first side plate is used to connect to an external hydraulic cylinder. After the secondary pressing is completed, the external hydraulic cylinder directly pushes the first movable chamber door to squeeze the material. After the material compression is completed, the second movable chamber door is opened. At this time, the first movable chamber door is pushed again until the material is pushed out from the second movable chamber door.

[0017] Furthermore, the inner wall of the third side plate is arc-shaped. Furthermore, the side edge of the free end of the second pressure plate is beveled.

[0018] Since the structure of metal scrap is not fixed and the size varies, in order to facilitate material collection, the inner wall of the third side plate of this utility model adopts an arc-shaped structure, that is, the corners are rounded and there are no right angle dead corners. At the same time, the side edge of the free end of the second pressure plate is beveled. In the secondary pressing process, the beveled edge design can increase the contact area with the arc-shaped inner wall, so that the beveled edge of the second pressure plate fits more tightly with the arc-shaped inner wall, so that all the metal scraps attached to the inner wall can be scraped downward into the closed mold cavity.

[0019] Furthermore, the first side plate and the third side plate are also provided with one or more sets of locking cylinder assemblies.

[0020] When the external hydraulic cylinder pushes the first movable chamber door to squeeze the material, the first side plate and the third side plate will bear the corresponding squeezing force. In order to improve the squeezing efficiency, the external hydraulic cylinder of this utility model has a higher power than that of the conventional one. Therefore, in order to improve the stress intensity of the first side plate and the third side plate, this utility model designs one or more sets of locking hydraulic cylinder assemblies on the first side plate and the third side plate respectively. By activating the locking hydraulic cylinder assembly, the material being squeezed is pushed against, thereby increasing the overall stress intensity.

[0021] Furthermore, a first locking port is provided above the first movable compartment door and the second movable compartment door respectively; a second locking port is provided on the side of the first movable compartment door and the second movable compartment door respectively; and a set of locking cylinder assemblies is provided on the first locking port and the second locking port respectively.

[0022] More preferably, this invention designs four sets of locking cylinder assemblies, one set each for the horizontal and vertical axes of the first and third side plates. One set of locking cylinder assemblies is fixed to the movable plate on the first locking port, and the other set is fixed to the movable plate on the second locking port. When the external cylinder extrudes the material, the locking cylinder assemblies are activated simultaneously, improving the stress strength of the entire sealed mold cavity.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] The material pressing bin assembly of this utility model adopts a top feeding method for initial pressing, followed by side pressing, and finally uses a movable second chamber door to achieve material discharge. The entire pressing process is short and efficient. At the same time, the two pressing operations, combined with the design of the arc-shaped inner wall of the second side of this utility model, avoid the material jamming problem caused by one-time extrusion in the prior art.

[0025] The pressing chamber assembly of this utility model mainly uses multiple hydraulic cylinders to quickly form a sealed mold cavity, which can realize multiple initial pressings and multiple feedings according to the feeding amount after feeding, for subsequent extrusion molding, thereby improving extrusion efficiency.

[0026] This invention features a multi-set locking hydraulic cylinder assembly that provides relative force when the external hydraulic cylinder compresses the material. This significantly increases the material's compression density while simultaneously increasing the overall stress intensity through multiple smaller cylinders, thus enhancing the stability of the entire compression chamber assembly. Furthermore, due to this increased overall stress intensity, the compression chamber assembly of this invention can utilize larger hydraulic cylinders with significantly higher power (even several times greater) than those used in existing technologies for final compression molding. This results in higher material density and a smaller volume. Simultaneously, the high-power compression significantly improves compression efficiency, allowing for more thorough extraction of waste liquids and oils from the waste material, resulting in a drier finished product that facilitates subsequent transportation.

[0038] Example

[0039] This embodiment provides a pressure hopper assembly, such as... Figure 1 As shown, it includes a pressure chamber body 1, a first pressure plate 2, a second pressure plate 3, a first drive module 4, and a second drive module 5. The first drive module 4 and the second drive module 5 each include two sets of hydraulic cylinder drive components. (Combined with...) Figure 2 As shown, the interior of the main body 1 of the pressing chamber is a pressing cavity 10, and the top is provided with a feed inlet 20, combined with... Figure 3 As shown, one end of the first pressure plate 2 is rotatably connected to one side of the main body 1 of the pressing chamber, and the other end of the first pressure plate 2 is rotatably connected to the second pressure plate 3; combined with Figure 4 As shown, the first drive module 4 is used to drive the first pressure plate 2 to rotate 90° relative to the pressure chamber body 1, thereby achieving one-time pressure on the pressure chamber 10; combined with Figure 5 As shown, the second drive module 5 is used to drive the second pressure plate 3 to continue rotating 90° toward the pressure chamber 10, so as to realize secondary pressure on the pressure chamber 10.

[0040] like Figure 6 As shown, the pressing chamber 10 is formed by a first side plate 11, a second side plate 12, a third side plate 13, a fourth side plate 14, and a bottom plate 15. The hydraulic cylinder drive is located on the outside of the fourth side plate 14. The first side plate 11 is provided with a first movable door 16, and the third side plate 13 is provided with a second movable door 17 symmetrical to the first movable door 16. The pressing chamber 10 of this utility model is an approximately rectangular cavity. The first movable door 16 of the first side plate 11 is used to connect to an external hydraulic cylinder. After the secondary pressing is completed, the external hydraulic cylinder directly pushes the first movable door 16 to squeeze the material. After the material compression is completed, the second movable door 17 is opened. At this time, the first movable door 16 is pushed again until the material is pushed out from the second movable door 17.

[0041] Combination Figure 7 As shown, the inner wall of the third side plate 13 is arc-shaped, combined with... Figure 1 and Figure 3 As shown, the side edge corresponding to the free end of the second pressure plate 3 is beveled. This increases the contact area with the arc-shaped inner wall, making the beveled edge of the second pressure plate 3 fit more tightly with the arc-shaped inner wall, allowing all metal shavings attached to the inner wall to be scraped downwards into the sealed mold cavity. After the secondary pressing, the first pressure plate 2, the second pressure plate 3, the bottom plate 15, the first side plate 11, the third side plate 13, and the fourth side plate 14 form a rectangular hexahedron shape.

[0042] like Figures 1-2 as well as Figure 6 and 8 As shown, two sets of locking cylinder assemblies 30 are respectively provided on the first side plate 11 and the third side plate 13. A first locking port 18 is provided above the first movable door 16 and the second movable door 17; a second locking port 19 is provided on the side of the first movable door 16 and the second movable door 17; and a set of locking cylinder assemblies 30 is provided on each of the first locking port 18 and the second locking port 19. A movable plate is provided on each of the first locking port 18 and the second locking port 19, and a set of locking cylinder assemblies 30 is connected to each movable plate. When the external cylinder compresses the material, the locking cylinder assemblies 30 are activated simultaneously, and the two opposing movable plates provide a driving force opposite to that of the external cylinder, thereby improving the pressure-bearing capacity of the first side plate 11 and the third side plate 13.

[0043] like Figure 3 and Figure 5 As shown, the main body 1 of the pressing chamber is provided with a first hinge component 6. One end of the two sets of hydraulic cylinders of the first drive module 4 is fixed to the main body 1 of the pressing chamber; the other end is connected to the first hinge component 6. The rotating end of the first hinge component 6 is connected to the first pressure plate 2. The rotating end of the first hinge component 6 is driven to rotate by the two sets of hydraulic cylinders of the first drive module 4, and the second pressure plate 3 is driven by the first pressure plate 2 to rotate synchronously toward the feed inlet 20 to a horizontal state. The pressing chamber assembly of this utility model also includes a second hinge component 7. One end of the second hinge component 7 is fixed to the first pressure plate 2, and the other end is a rotating end connected to the second pressure plate 3. One end of the two sets of hydraulic cylinders of the second drive module 5 is fixed to the first hinge component 6, and the other end is connected to the rotating end of the second hinge component 7. The two sets of hydraulic cylinders of the second drive module 5 are used to realize the rotation of the rotating end of the second hinge component 7, thereby driving the second pressure plate 3 to rotate.

[0044] In this embodiment, the two sets of hydraulic cylinder drive components of the second drive module 5 are located between the two sets of hydraulic cylinder drive components of the first drive module 4. The overall volume is smaller, and they are symmetrical in pairs, resulting in more uniform force distribution and higher stability during the push-pull process.

[0045] The main body 1 of the pressing chamber of this utility model has a square-like structure, and the second side plate 12 has a rounded arc structure. When the first pressing plate 2 and the second pressing plate 3 are open, the first pressing plate 2 and the second pressing plate 3 are on the same horizontal plane. After feeding material into the inlet 20, when the two sets of hydraulic cylinders of the first drive module 4 drive the first pressing plate 2 to rotate 90° relative to the fourth side plate 14, the first pressing plate 2 and the second pressing plate 3 cover the inlet 20, realizing the first pressing of the material in the pressing chamber 10. At this time, if there is a lot of empty space in the pressing chamber 10, the two sets of hydraulic cylinders of the first drive module 4 are used to drive the first pressing plate 2 to open. At this time, the inlet 20 is open, and secondary feeding can be carried out. Based on this embodiment, a sensor or corresponding scale can be set in the pressing chamber 10. When the warning line is reached after pressing, feeding will not continue. The second pressure plate 3 is then driven by two sets of hydraulic cylinders in the second drive module 5 to rotate 90° towards the pressing chamber 10, achieving secondary pressing of the pressing chamber 10. At this time, the first pressure plate 2 and the second pressure plate 3 are at 90°, so that the inner walls of the first pressure plate 2, the second pressure plate 3, the bottom plate 15, the first side plate 11, the third side plate 13, and the fourth side plate 14 form a rectangular hexahedral sealed mold cavity. An external hydraulic cylinder is connected to the outside of the first side plate 11. The external hydraulic cylinder pushes the first movable chamber door 16 to extrude and form the sealed mold cavity. At this time, the locking hydraulic cylinder assembly 30 is started synchronously to form a reverse thrust. After extrusion is completed, the second movable chamber door 17 is opened to push out the material, which is then processed and recycled.

Although this utility model has been described in detail with reference to the preferred embodiments above, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model should not depart from the spirit and scope of this utility model. Those skilled in the art can also make other changes within the spirit of this utility model for its design, as long as they do not deviate from the technical effect of this utility model.
