Description

Technical Field

[0001] This utility model relates to the field of material rack technology, specifically to a hydraulically based expansion guide mechanism. Background Technology

[0002] A pressure press for a hydraulic scrap metal baler refers to a pressure press used in conjunction with a hydraulic baler. In the process of baling scrap metal, in order to reduce the volume of scrap metal and improve transportation efficiency, a pressure press is usually used to compress the hydraulic metal, which is then used in conjunction with the baler to bale the metal, thereby improving production efficiency.

[0003] A search revealed that patent application number CN201920205616.0 discloses a hydraulic expansion rack. This device uses a hydraulic cylinder to drive the rack body to tension the steel coil. However, this device only focuses on the tensioning operation of the steel coil and lacks consideration for the guiding function of the coil during the conveying process. In terms of structural transmission, it only relies on the simple extension and retraction of the hydraulic cylinder piston rod to drive the rack body to move, and cannot achieve precise control over the extension and retraction of the movable sleeve and the expansion degree of the inner support plate. Its versatility and applicability are poor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a hydraulically based expansion and guiding mechanism, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A hydraulically based expanding material guiding mechanism includes a base on which an expanding mechanism is mounted;

[0007] The expansion mechanism includes a rotating shaft, one end of which is connected to a movable sleeve via a pipe thread. The expansion mechanism also includes a back plate, which is mounted on a base via a fixing frame. The rotating shaft passes through and is rotatably mounted inside the back plate. A fixing baffle is mounted on the back plate, and a sliding groove is provided on the fixing baffle. A fixing seat is provided on the movable sleeve, and an inner support plate is mounted on the fixing seat via a connecting rod. The end of the inner support plate is limited and slides within the sliding groove.

[0008] The movable sleeve is equipped with a blocking mechanism, which is used to block the material roll installed on the expansion mechanism. The two ends of the material roll are blocked by the fixed baffle and the blocking mechanism.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, when the movable sleeve moves, the movable sleeve drives the inner support plate to expand and retract via the fixed seat and connecting rod.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The rigid connection between the fixed seat and the connecting rod stably transforms the linear motion of the movable sleeve into the expansion and retraction of the inner support plate, ensuring the synchronicity and consistency of the inner support plate's movement. This allows the inner support plate to apply a uniform supporting force to the inner wall of the material roll, effectively preventing deformation or slippage of the material roll due to uneven force distribution and ensuring the reliability of the material roll's support and fixation.

[0013] Furthermore, the shielding mechanism includes a rack, which is fixed on a movable sleeve. The end of the rack is locked to the back plate by a nut. Movable baffles are rotatably installed on both sides of the movable sleeve via fixed plates, and the ends of the movable baffles are provided with gears. The movable baffles are expanded or retracted by the cooperation of the rack and the gears.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] By utilizing the meshing transmission of rack and pinion, the movable baffle can automatically expand and contract without the need for an additional drive device, simplifying the mechanism structure and reducing costs. At the same time, the movement of the movable baffle and the movable sleeve are linked. When the movable sleeve extends or retracts, the movable baffle can adjust its position synchronously to block and protect both ends of the material roll in a timely manner, effectively preventing the material roll from axially shifting or deviating during the material guiding process, thus improving the safety and stability of the material guiding operation.

[0016] Furthermore, the rotating shaft is equipped with a gear disc, and the rotating shaft is connected to the output end of the motor via a chain.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] Chain drives are characterized by accurate transmission ratios and high transmission efficiency. They can stably and accurately transmit the power of the motor to the shaft, ensuring that the shaft rotates at the set speed and torque, thereby precisely controlling the extension and retraction distance and speed of the movable sleeve. In addition, chain drives have a compact structure, occupy little space, and are easy to arrange in a limited space. They are also easy to maintain, which can effectively reduce equipment maintenance costs and downtime.

[0019] Furthermore, when the shaft rotates, the movable sleeve extends and retracts via the pipe thread.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] Pipe thread drive can efficiently convert the rotational motion of the shaft into the linear motion of the movable sleeve, with the advantages of smooth transmission and good self-locking performance. By adjusting the number of rotations of the shaft, the extension and retraction length of the movable sleeve can be precisely controlled, thereby achieving precise adjustment of the expansion degree of the inner support plate to adapt to material coils with different inner diameters, enhancing the versatility and applicability of the mechanism.

[0022] Furthermore, an oil tank is installed at the top of the base, an oil pump is installed on the oil tank, a hydraulic cylinder is installed on the base, a protective cover is installed on the outside of the hydraulic cylinder on the base, and one end of the hydraulic cylinder is connected and fixed to the rotating shaft. The hydraulic cylinder drives the rotating shaft to drive the movable sleeve to extend and retract. The oil pump and the hydraulic cylinder are connected through a conduit.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The hydraulic drive system consists of an oil pump, oil tank, hydraulic cylinder, and conduit, forming a complete circuit. It can provide large driving force and stable power output to meet the force requirements for the extension and retraction of the movable sleeve under different working conditions. The protective cover provides physical protection for the hydraulic cylinder, effectively preventing external debris and dust from entering the hydraulic cylinder, avoiding performance degradation or failure due to wear caused by impurities, extending the service life of the equipment, and ensuring the safety of operators by reducing the risk of accidental contact with moving parts.

[0025] Furthermore, the end of the inner support plate is provided with a pulley, and the pulley is located on both sides of the slide groove. The end of the inner support plate is limited by the pulley and slides within the slide groove.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The pulleys convert the sliding friction between the inner support plate and the fixed baffle into rolling friction, significantly reducing friction during movement. This makes the inner support plate slide more smoothly in the groove, reducing energy loss and improving the operating efficiency of the mechanism. At the same time, the pulleys limit the movement of the inner support plate on both sides of the groove, effectively constraining the movement trajectory of the inner support plate and preventing it from swaying or deviating during movement. This further enhances the stability and accuracy of the expansion and retraction of the inner support plate.

[0028] This invention provides a hydraulically based expanding material guiding mechanism. It has the following beneficial effects:

[0029] By cooperating with components such as a rotating shaft, movable sleeve, pipe thread, connecting rod, and inner support plate, the pipe thread drives the movable sleeve to extend and retract when the rotating shaft rotates, thereby causing the inner support plate to expand and retract, thus achieving the function of supporting and expanding the material coil. This mechanical transmission method is simple and reliable, and can accurately control the movement of the inner support plate.

[0030] The end of the inner support plate is limited to sliding within the groove of the fixed baffle by a pulley. This ensures the stability and accuracy of the movement of the inner support plate, while also reducing friction and improving the service life of the mechanism.

[0031] The blocking mechanism uses the cooperation of rack and pinion to expand or retract the movable baffle, which can effectively block the material roll installed on the expansion mechanism. Together with the fixed baffle, it blocks both ends of the material roll to prevent the material roll from shifting or falling during the material guiding process, thus improving the safety and stability of the material guiding process.

[0032] The system employs a hydraulic drive mechanism, where a hydraulic cylinder pushes a rotating shaft to extend and retract the movable sleeve. The hydraulic system boasts advantages such as high power output, smooth transmission, and fast response, enabling rapid and accurate movement of the expanding material guide mechanism. Furthermore, the oil pump and hydraulic cylinder are connected via conduits, facilitating the transmission and control of hydraulic oil and improving the overall system efficiency.

[0033] The shaft is connected to the motor output via a chain. The motor provides stable power, and the chain drive allows for precise control of the shaft's rotation. This, in turn, precisely controls the extension and retraction of the movable sleeve and the expansion and contraction of the inner support plate, thus achieving precise material guidance of the coil.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figures 1 to 7 As shown, the embodiments provided by this utility model are as follows:

[0047] Example 1

[0048] A hydraulically based expansion guiding mechanism includes a base 1, on which an expansion mechanism 5 is mounted. The expansion mechanism 5 includes a rotating shaft 502, one end of which is connected to a movable sleeve 508 via a pipe thread 513. When the rotating shaft 502 rotates, the movable sleeve 508 is driven to extend or retract via the pipe thread 513. The pipe thread 513 transmission can efficiently convert the rotational motion of the rotating shaft 502 into the linear motion of the movable sleeve 508, offering advantages such as smooth transmission and good self-locking performance. By adjusting the number of rotations of the rotating shaft 502, the extension or retraction length of the movable sleeve 508 can be precisely controlled, thereby achieving the extension or retraction of the inner support plate 505. The precise adjustment of the expansion degree to adapt to material rolls with different inner diameters enhances the versatility and applicability of the mechanism. The expansion mechanism 5 also includes a back plate 509, which is mounted on the base 1 via a fixing bracket 503. A rotating shaft 502 passes through and is rotatably mounted inside the back plate 509. A fixing baffle 504 is mounted on the back plate 509, and a sliding groove 511 is provided on the fixing baffle 504. A fixing seat 507 is provided on the movable sleeve 508, and an inner support plate 505 is mounted on the fixing seat 507 via a connecting rod 506. The end of the inner support plate 505 slides within the sliding groove 511 and is equipped with a pulley at the end of the inner support plate 505. 512, with pulleys 512 located on both sides of the slide groove 511, allows the end of the inner support plate 505 to slide within the slide groove 511, limited by pulleys 512. The pulleys 512 convert the sliding friction between the inner support plate 505 and the fixed baffle 504 into rolling friction, significantly reducing friction during movement. This makes the sliding of the inner support plate 505 within the slide groove 511 smoother, reducing energy loss and improving the mechanism's operating efficiency. Simultaneously, the pulleys 512, positioned on both sides of the slide groove 511, effectively constrain the movement trajectory of the inner support plate 505, preventing it from swaying or shifting during movement. To further improve the stability and accuracy of the expansion and retraction of the inner support plate 505, when the movable sleeve 508 moves, the movable sleeve 508 drives the inner support plate 505 to expand and retract through the fixed seat 507 and the connecting rod 506. Through the rigid connection of the fixed seat 507 and the connecting rod 506, the linear motion of the movable sleeve 508 is stably converted into the expansion and retraction of the inner support plate 505, ensuring the synchronicity and consistency of the movement of the inner support plate 505. This allows the inner support plate 505 to apply support force evenly to the inner wall of the material roll, effectively preventing the material roll from deforming or slipping due to uneven force, and ensuring the reliability of the material roll support and fixation.

[0049] The movable sleeve 508 is equipped with a blocking mechanism 6, which is used to block the material roll installed on the expansion mechanism 5. The two ends of the material roll are blocked by the fixed baffle 504 and the blocking mechanism 6.

[0050] Example 2

[0051] To promptly block and protect both ends of the material roll, effectively preventing axial movement or displacement during material guiding, and improving the safety and stability of the material guiding operation, for example, such as... Figures 1 to 7 As shown, this utility model also includes: a shielding mechanism 6 comprising a rack 601, which is fixed to a movable sleeve 508. The end of the rack 601 is locked to a back plate 509 by a nut. Movable baffles 603 are rotatably mounted on both sides of the movable sleeve 508 via fixed plates. A gear 602 is provided at the end of the movable baffle 603. The movable baffle 603 expands or contracts through the cooperation of the rack 601 and the gear 602. The automatic expansion and contraction of the movable baffle 603 is achieved by the meshing transmission of the rack 601 and the gear 602, without the need for an additional drive device, simplifying the mechanism structure and reducing costs. At the same time, the movement of the movable baffle 603 and the movable sleeve 508 are linked. When the movable sleeve 508 extends or retracts, the movable baffle 603 can adjust its position synchronously to block and protect both ends of the material roll in a timely manner, effectively preventing the material roll from axially shifting or deviating during the material guiding process, and improving the safety and stability of the material guiding operation.

[0052] Example 3

[0053] To provide high driving force and stable power output, and to meet the force requirements of the 508 telescopic sleeve under different working conditions, for example, such as Figures 1 to 7 As shown, this utility model also includes: an oil tank 4 installed at the top of the base 1, an oil pump 3 installed on the oil tank 4, a hydraulic cylinder 501 installed on the base 1, and a protective cover 2 installed on the base 1 outside the hydraulic cylinder 501. The hydraulic cylinder 501 is connected and fixed to one end of the rotating shaft 502. The hydraulic cylinder 501 drives the rotating shaft 502 to drive the movable sleeve 508 to extend and retract. The oil pump 3 is connected to the hydraulic cylinder 501 through a conduit. The hydraulic drive system, with the oil pump 3, oil tank 4, hydraulic cylinder 501 and conduit forming a complete circuit, can provide large driving force and stable power output to meet the force requirements for the extension and retraction of the movable sleeve 508 under different working conditions. The protective cover 2 provides physical protection for the hydraulic cylinder 501, effectively preventing external debris and dust from entering the hydraulic cylinder 501. Internally, to prevent the hydraulic cylinder 501 from experiencing performance degradation or malfunction due to wear caused by impurities, thus extending the equipment's service life and ensuring operator safety by reducing the risk of accidental contact with moving parts, a geared disc 510 is installed on the rotating shaft 502. The rotating shaft 502 is connected to the output end of the motor 7 via a chain drive. The chain drive features accurate transmission ratio and high transmission efficiency, enabling it to stably and accurately transmit the power of the motor 7 to the rotating shaft 502, ensuring that the rotating shaft 502 rotates according to the set speed and torque, thereby precisely controlling the extension distance and speed of the movable sleeve 508. In addition, the chain drive structure is compact, occupies little space, and is easy to arrange in a reasonable manner within a limited mechanical space. It is also easy to maintain, effectively reducing equipment maintenance costs and downtime.

[0054] Working principle:

[0055] The material roll to be guided is placed on the expanding guiding mechanism. At this time, the inner support plate 505 is in the retracted state, and the movable baffle 603 is also in the retracted state, which facilitates the installation of the material roll. After the material roll is installed in place, it is ready for subsequent work.

[0056] When oil pump 3 is turned on, it begins to work, delivering hydraulic oil from oil tank 4 to hydraulic cylinder 501 through conduits. The hydraulic oil forms a pressurized flow in the conduits, driving the piston of hydraulic cylinder 501 to move and providing initial power for the mechanism's operation.

[0057] Hydraulic cylinder 501 directly drives rotating shaft 502. Since one end of rotating shaft 502 is connected to movable sleeve 508 through pipe thread 513, the linear movement of rotating shaft 502 causes movable sleeve 508 to initially extend and retract. At this time, the movement of movable sleeve 508 lays the foundation for subsequent precise adjustment, bringing inner support plate 505 and movable baffle 603 close to the working position.

[0058] A geared disc 510 is mounted on the rotating shaft 502, which is connected to the output end of the motor 7 via a chain. After the motor 7 starts, it drives the rotating shaft 502 to rotate. Utilizing the helical transmission principle of the pipe thread 513, the movable sleeve 508 can perform more precise extension and retraction after initial movement. This rotational drive method enables fine adjustment of the position of the movable sleeve 508, ensuring that the inner support plate 505 and the movable baffle 603 reach their optimal working state.

[0059] The movable sleeve 508 drives the inner support plate 505 to move via the fixed base 507 and the connecting rod 506. The end of the inner support plate 505 is limited and slides within the groove 511 of the fixed baffle 504 via the pulley 512. With the precise movement of the movable sleeve 508, the inner support plate 505 expands outward along the direction of the groove 511 under the action of the connecting rod 506 until the inner support plate 505 is in close contact with the inner wall of the material roll, thus achieving stable support and fixation of the material roll.

[0060] During the extension and retraction of the movable sleeve 508, the rack 601 fixed to it moves accordingly. The end of the movable baffle 603 is provided with a gear 602, and the rack 601 and the gear 602 mesh with each other. As the rack 601 moves, it drives the gear 602 to rotate, thereby causing the movable baffle 603 to rotate and unfold around the fixed plate. Together with the fixed baffle 504, it blocks both ends of the material roll to prevent the material roll from deviating or falling during the material guiding process.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0062] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
