Description

Technical Field

[0001] This invention relates to the field of nonwoven fabrics, and more specifically, to a hydraulic packaging device for nonwoven fabrics. Background Technology

[0002] Nonwoven fabrics are fabrics formed without spinning or weaving. They are made by arranging short or long textile fibers in a directional or random manner to form a web structure, which is then reinforced by mechanical, thermal, or chemical methods. Hydraulic balers are used in the production of nonwoven fabrics. Traditional hydraulic balers have multiple gaps in their forming chambers to facilitate the operation of threading steel wires to bind the compressed waste fabric. This method is time-consuming and labor-intensive. Therefore, providing a more convenient hydraulic baling device for nonwoven fabrics is crucial. In view of this, we propose a hydraulic baling device for nonwoven fabrics. Summary of the Invention

[0003] 1. Technical problems to be solved

[0004] The purpose of this invention is to provide a hydraulic packaging device for nonwoven fabrics to solve the problems mentioned in the background art.

[0005] 2. Technical Solution

[0006] A hydraulic packing device for nonwoven fabrics includes a frame and a hydraulic cylinder mounted on the top plate of the frame. It further includes: a pressing mechanism disposed inside the frame and connected to the movable end of the hydraulic cylinder; a load-bearing mechanism disposed inside the lower side of the frame; wherein both the pressing mechanism and the load-bearing mechanism are provided with a winding structure; wherein the winding structure is a continuous, closed-loop infeed; an extension mechanism disposed on the front of the frame and connected to the load-bearing mechanism; a side-blocking mechanism disposed on the side of the frame; wherein the extension mechanism, side-blocking mechanism, load-bearing mechanism, and pressing mechanism form a fabric pressing cavity; and a winding mechanism disposed outside the side-blocking mechanism and connected to the winding structure. This invention improves the structure of existing hydraulic balers by incorporating a continuous, closed-loop winding structure on both the pressing and supporting mechanisms. After the waste fabric is pressed and shaped in the pressing chamber, the pressing and supporting mechanisms shift axially outward from the frame. At this point, the side stop mechanism opens, allowing the winding structure to be coplanar with the coiling mechanism. This enables the coiling mechanism to wind steel wire from the winding structure, continuously and irreversibly pressing the wound wire into the winding structure, thus securing the pressed fabric. Finally, when the pressing and supporting mechanisms reset, the fabric is conveyed out of the pressing chamber via the extension mechanism, completing the baling process. This invention offers strong mechanical advantages, avoids manual baling, saves time and labor, and improves the processing efficiency of nonwoven fabrics.

[0007] Preferably, both the pressing mechanism and the load-bearing mechanism include: a carrier plate; a main plate arranged on the opposite surface of the carrier plate; wherein a double-rod cylinder is provided between the main plate and the carrier plate, the fixed end of the double-rod cylinder is connected and fixed to the carrier plate, and the movable end of the double-rod cylinder is connected and fixed to the main plate; wherein the main plate and the carrier plate are slidably connected; at least one secondary plate arranged at the axial end of the main plate; wherein the secondary plate is gap-connected to the main plate through a winding structure.

[0009] Preferably, both the male tooth and the female tooth have beveled ends. The high end of the beveled end is connected to the slot, and the low end of the beveled end is connected to the insertion port. The two beveled ends meet to form a guide angle. Both the male tooth and the female tooth have right-angled grooves near their tail ends. The beveled side of the right-angled groove is slidably connected to the beveled protrusion on the inner wall of the slot.

[0010] Preferably, the elastic element includes a screw that passes through the slot, the screw head having a countersunk hole, a spring being provided in the countersunk hole, the spring abutting against a steel ball embedded in the inlet of the countersunk hole, and the surface of the steel ball contacting the square holes opened on the male tooth and the female tooth.

[0011] Preferably, the extension mechanism includes: a pushing component, arranged on the frame base plate and connected to the carrier plate in the load-bearing mechanism; a stop door, arranged on the front of the frame and hinged to the frame base plate; and a guiding component, in a segmented structure, arranged on the frame base plate and the inner wall of the stop door and connected to the carrier plate in the load-bearing mechanism.

[0014] Preferably, the translation distance of the winding structure intersects with the vertical plane where the wire coil is located.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of this invention are:

[0017] This invention improves the structure of existing hydraulic balers by incorporating a continuous, closed-loop winding structure on both the pressing and supporting mechanisms. After the waste fabric is pressed and shaped in the pressing chamber, the pressing and supporting mechanisms shift axially outward from the frame. At this point, the side stop mechanism opens, allowing the winding structure to be coplanar with the coiling mechanism. This enables the coiling mechanism to wind steel wire from the winding structure, continuously and irreversibly pressing the wound wire into the winding structure, thus securing the pressed fabric. Finally, when the pressing and supporting mechanisms reset, the fabric is conveyed out of the pressing chamber via the extension mechanism, completing the baling process. This invention offers strong mechanical advantages, avoids manual baling, saves time and labor, and improves the processing efficiency of nonwoven fabrics. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Please see Figures 1-8 The present invention provides a technical solution:

[0034] A hydraulic packaging device for nonwoven fabrics includes a frame 1 and a hydraulic cylinder 2 passing through the top plate of the frame 1. It further includes: a pressing mechanism 3 arranged inside the frame 1 and connected to the movable end of the hydraulic cylinder 2; a load-bearing mechanism 4 arranged inside the lower side of the frame 1; wherein both the pressing mechanism 3 and the load-bearing mechanism 4 are provided with a winding structure 5; wherein the winding structure 5 is a continuous, closed-type wire inlet; an extension mechanism 6 arranged on the front of the frame 1 and connected to the load-bearing mechanism 4; a side-blocking mechanism 7 arranged on the side of the frame 1; wherein the extension mechanism 6, the side-blocking mechanism 7, the load-bearing mechanism 4, and the pressing mechanism 3 form a fabric pressing cavity; and a winding mechanism 8 arranged outside the side-blocking mechanism 7 and connected to the winding structure 5. Figure 1 and Figure 2 As shown, this invention improves the structure of existing hydraulic balers by incorporating a continuous, closed-loop winding structure 5 on both the pressing mechanism 3 and the load-bearing mechanism 4. After the waste fabric is pressed and shaped in the fabric pressing chamber, the pressing mechanism 3 and the load-bearing mechanism 4 move axially outward from the frame 1. At this time, the side stop mechanism 7 opens, allowing the winding structure 5 to be coplanar with the winding mechanism 8. This enables the winding mechanism 8 to wind steel wire from the winding structure 5. The wound steel wire is continuously and irreversibly pressed into the winding structure 5, thus fixing the pressed fabric. Finally, when the pressing mechanism 3 and the load-bearing mechanism 4 reset, the fabric is sent out of the fabric pressing chamber via the extension mechanism 6, completing the baling of the waste fabric. This invention has strong mechanical properties, avoids manual baling of fabric, saves time and labor, and is beneficial to improving the processing efficiency of nonwoven fabrics.

[0035] For ease of understanding, such as Figure 3 and Figure 4 As shown, the present invention also discloses a more detailed structural schematic diagram of the pressing mechanism 3 and the load-bearing mechanism 4, both of which include:

[0036] The carrier plate 9 in the pressing mechanism 3 is connected to the movable end of the hydraulic cylinder 2 and is slidably connected to the top plate of the frame 1 through multiple guide rods, so that the carrier plate 9 in the pressing mechanism 3 can be stably and linearly raised and lowered within the frame 1; the carrier plate 9 in the load-bearing mechanism 4 is connected to the extension mechanism 6.

[0037] Mainboard 10 is arranged on the opposite side of carrier board 9;

[0038] A double-rod cylinder 11 is provided between the main board 10 and the carrier board 9. The fixed end of the double-rod cylinder 11 is connected and fixed to the carrier board 9, and the movable end of the double-rod cylinder 11 is connected and fixed to the main board 10. The double-rod cylinder 11 in this invention is embedded in the main board 10. By using the extension and retraction of the double-rod cylinder 11, the main board 10, the sub-board 12 and the winding structure 5 can be axially translated on the frame 1, thereby facilitating the subsequent steel wire dyeing work.

[0039] The motherboard 10 and the carrier board 9 are slidably connected. Specifically, the motherboard 10 is provided with a guide groove, and the carrier board 9 is provided with a guide rib corresponding to the guide groove. The guide rib is an inverted trapezoidal structure, which allows the guide rib to slide with the guide groove to limit the movement and improve the stability of the sliding between the motherboard 10 and the carrier board 9.

[0040] At least one sub-plate 12 is arranged at the axial end of the main plate 10; in this embodiment, the present invention provides sub-plates 12 at both axial ends of the main plate 10, which facilitates the winding and fixing of the pressed fabric from both ends.

[0041] The secondary plate 12 is connected to the main plate 10 through a gap in the winding structure 5, which facilitates continuous wire-locked infeed.

[0042] It is worth noting that, for example, an implementation Figure 5 and Figure 6 As shown, the winding structure 5 is composed of multiple sets of linearly arranged locking teeth 501, and the locking teeth 501 include:

[0043] Male tooth 502 is inserted into the axial end face of the motherboard 10;

[0044] The female tooth 503 is inserted into the axial end face of the sub-plate 12;

[0045] Among them, the female tooth 503 and the male tooth 502 are arranged in a centrally symmetrical manner, and the opposite insertion method is conducive to improving the bending resistance of the connection gap between the main board 10 and the sub-board 12.

[0046] Among them, the male tooth 502 and the female tooth 503 are both inserted into the slot 505 with an elastic member 504 that is far away from the carrier plate 9, so as to facilitate the reset after the steel wire is pressed in.

[0047] Both the male tooth 502 and the female tooth 503 have a post head 506 on their back ends. The post head 506 hooks and engages with the insertion port 507 on the main board 10 and the sub-board 12. In this embodiment, the wire is wound clockwise by the winding mechanism 8. To avoid the clockwise wound wire from getting caught on the post head 506 and to ensure the smooth winding of the wire, the post head 506 is set on the side away from the winding direction of the wire. The purpose of setting the post head 506 is to realize that the wire is continuously and irreversibly pressed into the gap between the main board 10 and the sub-board 12, while using the snap-fit ​​structure of the post head 506 to ensure the stability of the lateral connection between the main board 10 and the sub-board 12.

[0048] It is worth noting that both the male tooth 502 and the female tooth 503 have beveled surfaces 509 at their ends. When the steel wire contacts the beveled surface 509, the reaction force imparts a horizontal vector and a vertical vector to the beveled surface 509, facilitating the retraction movement of the male tooth 502 and the female tooth 503. The high end of the beveled surface 509 connects to the slot 505, and the low end connects to the insertion port 507. The two beveled surfaces 509 intersect at their front ends to form a guide angle 508.Figure 3 As shown, the guide angle 508 is a triangular cavity with a bottom formed by two centrally symmetrical inclined surfaces 509. Both the male tooth 502 and the female tooth 503 have right-angle grooves 510 near their tail ends. The inclined side of the right-angle groove 510 is slidably connected to the inclined protrusion 511 on the inner wall of the slot 505. When the steel wire squeezes the inclined surface 509 to generate a horizontal vector and a vertical vector, both the male tooth 502 and the female tooth 503 can slide downwards under the guidance of the inclined protrusion 511. At this time, the column head 506 is pushed out from the insertion port 507 in this sliding direction until the male tooth 502 or the female tooth 503 is pushed out from the insertion port 507 and a gap is created, so that the steel wire can slide from the bottom end of the inclined surface 509 into the gap between the main plate 10 and the sub-plate 12 (the dimensions of the above structure should be set according to the specific implementation situation, but are not limited here). After the steel wire slides into the gap between the main plate 10 and the sub-plate 12 after the above action, the winding and fixing of the pressed fabric can be achieved.

[0049] In addition, such as Figure 6 As shown, the elastic element 504 includes a screw 512 that passes through the slot 505. The head of the screw 512 has a countersunk hole 513. A spring 514 is provided in the countersunk hole 513. The spring 514 abuts against a steel ball 516 embedded in the inlet of the countersunk hole 513. The surface of the steel ball 516 contacts the square holes 515 opened on the male tooth 502 and female tooth 503 (the dimensions of the above structure should be set according to the specific implementation situation, but are not limited here). This facilitates the reset of the male tooth 502 or female tooth 503 that is squeezed by the steel wire. When the steel wire squeezes a male tooth 502 or female tooth 503, its adjacent female tooth 503 or male tooth 502 maintains the fixed connection between the main board 10 and the sub-board 12.

[0050] For ease of understanding, such as Figure 7 As shown, the present invention also discloses a more specific structural schematic diagram of the extension mechanism 6, which includes:

[0051] The pushing component 601 is arranged on the base plate of the frame 1 and connected to the carrier plate 9 in the load-bearing mechanism 4. In this embodiment, the pushing component 601 is a stable moving structure realized by a motor-driven lead screw. This structure is a commonly used existing structure and will not be described in detail here. As another embodiment, the pushing component 601 can also be a moving structure directly pushed by a cylinder.

[0052] Door 602 is arranged on the front hinged base plate of frame 1;

[0053] The guide assembly 603 is arranged in a segmented structure on the base plate of the frame 1 and the inner wall of the barrier 602, and is connected to the carrier plate 9 in the load-bearing mechanism 4. The guide assembly 603 consists of a guide rail and a slider that slides on the guide rail. The guide rail is segmented and set on the base plate of the frame 1 and the inner wall of the barrier 602. The gap between the segmented guide rails is adapted to the length of the slider, so that the slider can slide from the guide rail on the base plate of the frame 1 to the guide rail on the inner wall of the barrier 602, thereby pushing the pressed fabric out of the fabric pressing cavity.

[0054] For ease of understanding, such as Figure 8 As shown, the present invention also discloses a more specific structural schematic diagram of the side guard mechanism 7, which includes:

[0055] Enclosure 701 is arranged on the side of frame 1;

[0056] Insert plate 702 is arranged at the lower part of enclosure plate 701 and connected to the bottom plate of frame 1;

[0057] Among them, the insert plate 702 is slidably connected to the surrounding plate 701;

[0058] The length of the insert plate 702 is adapted to the width of the sub-plate 12, which facilitates the axial translation of the pressing mechanism 3 and the load-bearing mechanism 4 into the frame 1.

[0059] A single-rod cylinder 703 is arranged at the top of the enclosure 701 and connected to the insert plate 702. After the pressing mechanism 3 and the load-bearing mechanism 4 press the waste fabric into shape, the single-rod cylinder 703 drives the insert plate 702 to slide upward on the enclosure 701, which facilitates the pressing mechanism 3 and the load-bearing mechanism 4 to move out of the frame 1. When the waste fabric is being pressed, the insert plate 702 acts as a baffle, which is beneficial to the pressing and shaping of the waste fabric.

[0060] For ease of understanding, the present invention also discloses a more detailed structural schematic diagram of the winding mechanism 8, which includes:

[0061] The wire end fastener 801 is arranged on the enclosure 701. The wire end fastener 801 in this invention consists of a fixed base with a through hole and an adjusting handwheel on the fixed base. After passing the free end of the steel wire through the through hole on the fixed base, the adjusting handwheel is rotated to press the free end of the steel wire.

[0062] At least four feed rollers 802 are arranged in a square structure on the lower side of the frame 1; in one embodiment, there are 6 feed rollers 802, which form a hexagon with equal angles but unequal sides. The purpose is to facilitate the winding of the fabric pressed into a square shape and reduce the structural layout space.

[0063] A drive belt 803 is wound around multiple feed rollers 802. In order to improve the stability of the drive belt 803 fixing the insert 805, two drive belts 803 with gaps are provided. In another embodiment, the drive belt 803 can be made into a wide-face drive belt 803 to improve the stability of the insert 805 installation.

[0064] The transmission belt 803 has an end 804 on its surface. The end 804 in this invention is round, which helps to reduce the connection area with the transmission belt 803 and avoids the structure from being squeezed and deformed when passing through the feed roller 802, thus reducing its service life.

[0065] Among them, an insert 805 is inserted through the end 804;

[0066] A drive motor 806 is mounted on the frame 1 and connected to one of the feed rollers 802;

[0067] A wire coil 807 is inserted into the outer end of a tube 805; a post adapted to the tube 805 is provided on one side end face of the wire coil 807, and the post and the tube 805 are fixed by a through screw.

[0068] It is worth mentioning that the translational distance of the winding structure 5 intersects with the vertical plane where the wire coil 807 is located. Even when the wire coil 807 is wound clockwise, the wire can be continuously and irreversibly pressed into the winding structure 5, thereby achieving the winding and fixing of the pressed and shaped fabric.

[0069] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
