Description

Technical Field

[0001] This utility model relates to the field of baling machine technology, and in particular to a baling machine capable of bidirectional material discharge. Background Technology

[0002] Horizontal balers typically employ a horizontal feeding and compression method to compress loose materials (such as waste paper, plastic, cardboard, etc.) into regular blocks, which are then bundled using wire, steel straps, or plastic straps via an automatic strapping device. Currently, most horizontal hydraulic balers on the market use unidirectional discharge. For example, the side-discharge horizontal baler with publication number CN 208761058 U uses unidirectional side discharge; the hydraulic horizontal baler with buffer door safety device and publication number CN 216076782 U uses unidirectional horizontal discharge. The above-mentioned unidirectional discharge balers have the following problems in actual use: 1. The pusher extension can only push material on one side, resulting in low discharge efficiency; 2. A single material inlet and a single material baling area mean that only one type of material can be baled, leading to low baling efficiency; 3. During material sorting, one type of material enters the baler, while the other type of material screened out needs to be stacked in the yard and re-collected and baled, increasing the baling process. Using two devices for baling processing increases costs. Utility Model Content

A wire groove is left between two adjacent clamping arm plates. One end of the clamping arm plate is hinged to the crossbeam plate through a second pin.

[0012] Further preferably, the longitudinal drive mechanism includes a clamping arm base disposed on the side wall of the corresponding packaging area of ​​the chassis, and a longitudinal drive component is provided on the clamping arm base.

[0028] 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.

[0029] Example 1, such as Figure 1 As shown, a double-headed baling machine includes a chassis 1, which is a rectangular steel structure, with its length defined as transverse. In this embodiment, both ends of the chassis 1 are provided with transverse discharge ports 100, i.e., the chassis adopts a double discharge port. A bidirectional pusher 9, corresponding to the transverse discharge ports 100, is provided in the middle of the chassis 1. The bidirectional pusher can push material in both forward and backward directions, allowing for simultaneous pushing in both directions or a single extension and retraction action, enabling pushing in one direction while not pushing in the other, thus making the pushing method more flexible. The inner cavity of the chassis corresponding to the bidirectional pusher 9 and the corresponding transverse discharge port 100 is sequentially set as a feeding area and a baling area along the discharge direction. Therefore, in this embodiment, the chassis has two feeding areas and two baling areas, allowing for the simultaneous baling of two types of materials. A feeding hopper 2 is provided on the upper part of the chassis 1 corresponding to the feeding area. In this embodiment, the chassis has two feeding hoppers, which can be used for simultaneous feeding of two types of materials, avoiding the re-collection of materials screened before feeding, simplifying the screening work before baling, and improving the efficiency of the entire baling process. This embodiment, through the cooperation of the bidirectional pusher with double feed hoppers, double packaging areas and two lateral discharge ports, can simultaneously package two types of materials and push them out of the chamber synchronously or asynchronously, thereby improving packaging efficiency and discharge efficiency. This double-headed packaging machine integrates two packaging devices, which greatly increases production capacity while reducing production costs, meeting market demands.

[0030] Example 2, as Figure 10As shown, a double-headed baling machine is further optimized based on embodiment 1. In this embodiment, a door 4 is provided at the transverse discharge port 100, forming a double-headed baling machine with a door. The door 4 can be an upward-opening door or a side-opening door; a wire-passing groove II 43 is provided on the panel of the door 4 facing the inside of the machine housing 1; the wire-passing groove II 43 corresponds to the wire-passing groove 11 opened on the side wall of the machine housing 1 in the baling area; it is used for the smooth passage of the binding rope. After the material is compressed and shaped, the binding rope is led out through the wire-passing groove and the wire-passing groove for easy knotting, thus completing the rapid binding of the material.

[0031] Example 3, a double-headed strapping machine, is further optimized based on Example 1. In this example, the machine housing 1 corresponding to the strapping area is provided with a top pressing mechanism 3 and / or a side clamping mechanism 13, forming an upper-pressing or clamping-arm strapping machine, such as... Figure 1 The image shows a clamp-arm type baler. A top clamping mechanism 3 is installed at the top for downward, single-sided compression molding of the material in the baling area; side clamping mechanisms 13 are installed on both sides for double-sided, inward clamping compression molding of the material in the baling area; a combination of a top clamping mechanism 3 at the top and side clamping mechanisms 13 on both sides allows for downward pressure and double-sided clamping compression molding of the material in the baling area, a three-sided compression molding process. The specific configuration can be selected based on actual needs.

[0032] Example 4, as Figure 2 As shown, a double-headed baling machine is further optimized based on embodiment 1, 2, or 3. In this embodiment, the bidirectional pusher 9 includes a bidirectional hydraulic cylinder 91 and two symmetrically arranged push plates 92. The two push plates 92 are respectively connected to both ends of the bidirectional hydraulic cylinder 91. The push plates 92 slide or roll with the machine housing 1. When the push plates 92 slide with the machine housing 1, the push plates directly contact the machine housing 1, and there is sliding contact between the two. When the push plates 92 roll with the machine housing 1, rollers are provided at the bottom of the push plates or at the bottom of the machine housing, and rollers are provided between the push plates and the machine housing 1, and there is rolling contact between the two. It should be noted that the bidirectional hydraulic cylinder can be a double-headed hydraulic cylinder or a single-headed cylinder. When using a double-headed hydraulic cylinder, both ends can work synchronously to compress the material in the two baling areas simultaneously or alternately; alternatively, either end can work independently, stopping one pusher and allowing the other pusher to work independently. When operating synchronously at both ends, the cylinder is fixed, one piston rod extends while the other retracts, and both piston rods move synchronously to alternately compress the material at both ends; alternatively, both piston rods can extend and retract synchronously to compress the material in both packaging areas simultaneously. When operating at one end, the cylinder is fixed, one piston rod stops working, and the other piston rod extends and retracts independently to compress the material at that end. When using a single-head cylinder, two single-head cylinders are required, with their piston rods connected to two push plates respectively; this also allows for simultaneous or individual operation of the two push plates.

[0033] As a preferred embodiment, the pusher plate 92 in this embodiment is a box-type structure with an open rear end, ensuring stable movement within the casing 1 while maintaining high strength for efficient material pushing and compression. In this embodiment, the pusher plate 92 is slidably positioned within the casing. A reinforcing plate 93 is provided on the front end face of the pusher plate 92 to improve its pushing stability. Several threading grooves Ⅰ94 are longitudinally formed on the reinforcing plate 93; these threading grooves Ⅰ94 correspond to the thread-passing grooves 11 on the side wall of the casing 1 in the packaging area; they facilitate the smooth passage of binding ropes. After the material is compressed and formed, the binding ropes are led out through the thread-passing grooves and thread-passing grooves for easy knotting, completing the rapid binding of the material. In this embodiment, a hydraulic cylinder support 95 is provided in the middle of the casing 1, and a bidirectional hydraulic cylinder 91 is laterally positioned on the hydraulic cylinder support 95. The hydraulic cylinder support provides stable support for the bidirectional hydraulic cylinder 91.

[0034] Example 5, as Figure 4 As shown, a double-headed baling machine is further optimized based on embodiments 1, 2, 3, or 4. In this embodiment, the machine housing 1 corresponding to the baling area is provided with a top pressing mechanism 3 and / or a side clamping mechanism 13. By setting the top pressing mechanism 3 at the top, it is used to perform downward single-sided compression forming of the material in the baling area. By setting the side clamping mechanisms 13 on both sides, it is used to perform double-sided clamping compression forming of the material in the baling area. By setting the top pressing mechanism 3 at the top and the side clamping mechanisms 13 on both sides, it is used to perform downward pressing and double-sided clamping three-sided compression forming of the material in the baling area. The specific situation can be determined according to the actual situation. The appropriate method is selected based on the actual situation; the above-mentioned clamping structure, together with the door 4 at the transverse discharge port 100, forms a comprehensive baler; the opening and closing of the transverse discharge end is achieved by opening and closing the door, which is also used for switching between two modes. This comprehensive baler has two working modes: clamp arm baling mode and door baling mode; in clamp arm baling mode, the door is open, which is used for continuous baling of large quantities of materials to ensure baling efficiency; in door baling mode, the door is closed, and the materials can be small, loose materials such as shredded paper and aluminum cans, or large materials such as cardboard boxes, which are mainly for working conditions with fewer materials. This mode is used for non-continuous baling operations.

[0035] In this embodiment, the top pressing mechanism 3 includes an upper pressing plate 31. An upper driving member 32 is provided on the housing 1 to drive the upper pressing plate 31 downwards. Under the action of the upper driving member 32, the upper pressing plate 31 can perform a vertical downward pressing action in the packaging area. The upper pressing plate matches the upper opening of the housing to cover the upper part of the packaging area. The driving member provides the power for the upper pressing plate to move up and down. When moving downwards, it can press down on the material in the packaging area, compacting the material in that area for easy packaging. Specifically, in this embodiment, one end of the upper pressing plate 31 near the feed hopper 2 is hinged to the housing 1 via a first longitudinal pin 34, and the other end corresponds to the hatch 4. Under the action of the driving member, it rotates up and down around the hinge point, or swings up and down, applying a greater force to the material near the hatch area, while the material near the feed hopper area experiences relatively less force. Thus, the material pile pressed out by the upper pressing plate is conical. Under the pushing action of the transverse pusher, the material forms a conical discharge, which facilitates discharge and further compacts the material laterally, improving the material forming rate. The correspondence between the upper pressure plate and the hatch 4 means that when not pressing down, the upper pressure plate is in contact with the hatch or has a small gap to prevent the spillage of fine materials; when pressing down, the upper pressure plate and the hatch will not interfere with each other. The upper drive component 32 is a vertically arranged first hydraulic cylinder, which is connected to the machine housing 1 through a support base 35. The telescopic end of the first hydraulic cylinder is hinged to the upper pressure plate 31. Specifically, the telescopic end of the first hydraulic cylinder is hinged to the upper pressure plate using a pin, and the connecting pin is located at about 1 / 5 of the front part of the upper pressure plate to ensure that the material in the packaging area is pressed down and compacted obliquely and evenly. It should be noted that the drive component can also be a cylinder if needed. The drive component that provides the power for up and down movement and the first telescopic hydraulic cylinder belong to the same inventive concept.

[0036] In this embodiment, the side clamping mechanism 13 includes clamping arm plates 132 disposed on the left and right sides of the casing 1 and a longitudinal drive mechanism for driving the clamping arm plates 132 to perform clamping actions. The clamping arm plates almost cover the side of the casing, ensuring simultaneous clamping and compression of the entire side of the packaging area. Under the action of the longitudinal drive mechanism, the clamping arm plates 132 can perform longitudinal clamping actions in the packaging area. As shown in the figure, the Y direction represents the transverse direction, the X direction represents the longitudinal direction, and the Z direction represents the vertical direction. The longitudinal drive mechanism provides the force required for the clamping action of the corresponding clamping arm plates, ensuring that the material in the packaging area is uniformly compressed and shaped on both sides. Several parallel crossbeam plates 12 are provided on both the left and right sides of the casing 1 in the packaging area. The clamping arm plates 132 are arranged one-to-one with the crossbeam plates 12. The clamping arm plates 132 have a U-shaped structure and are inserted and slidably engaged with the crossbeam plates. The front panel of the clamping arm plates 132 is located inside the casing. The front panel is a smooth panel to reduce frictional resistance and facilitate the passage of the packaging material. A wire groove 11 is provided between two adjacent clamping arm plates 132. The wire groove facilitates the passage and exit of the binding rope, and makes it easy to bind and knot. One end of the clamping arm plate 132 is hinged to the crossbeam plate 12 through the second pin 134. Multiple clamping arm plates 132 swing back and forth synchronously around the second pin under the action of the longitudinal drive mechanism, clamping the material in the packaging area on both sides, forming a two-sided extrusion, which facilitates rapid forming.

[0037] like Figure 5 , 7 As shown, the longitudinal drive mechanism in this embodiment adopts linear longitudinal drive. Specifically, the longitudinal drive mechanism includes a clamping arm base 3-1 set on the side wall of the packaging area of ​​the chassis 1. The clamping arm base 3-1 is provided with a longitudinal drive component 133, which is a first telescopic hydraulic cylinder. The first telescopic hydraulic cylinder is fixed inside the clamping arm base 3-1, and the rod of the first telescopic hydraulic cylinder extends out of the clamping arm base 3-1 and is connected to a connecting plate seat 3-2. The connecting plate seat 3-2 is correspondingly arranged with the clamping arm plate 132. The clamping arm base adopts a box-type seat, and the telescopic hydraulic cylinder is fixed inside the clamping arm base, which makes the structure more compact and provides dust protection. The connecting plate seat can be connected to the rod of the telescopic hydraulic cylinder using bolts. The connecting plate seat 3-2 is correspondingly arranged with the clamping arm plate 132; the longitudinal drive component drives the clamping arm plate to move through the connecting plate seat, so that it is evenly stressed. The connecting plate seat 3-2 and the clamping arm plate 132 can be connected by a pin hinge. Power transmission is carried out by contact rather than connection. During the compression action, the longitudinal telescopic cylinder contacts the rear support plate of the clamping arm plate through the connecting plate seat and pushes the clamping arm plate to move into the machine box to squeeze and compact the material in the packaging area. After compaction and packaging, the telescopic cylinder retracts, the connecting plate seat disengages from the clamping arm plate, and the clamping arm plate is pushed back to its original position by the pusher plate of the transverse pusher during the material pushing process.

[0038] Example 6, as Figure 6 , 8As shown, a double-head baler is further optimized based on Embodiment 1 or 2. The difference between this embodiment and Embodiment 3 is that the longitudinal drive mechanism in this embodiment adopts a rotary shaft drive, specifically including rotary shaft arm assemblies 131 arranged on both sides of the transverse outlet. A longitudinal drive component 133 connects the two rotary shaft arm assemblies 131 on both sides, linking them together to ensure that the clamping arm plates on both sides simultaneously perform clamping and compression actions. The clamping arm plates 132 are arranged on the left and right sides of the machine housing 1, near the hatch 4; they clamp the material near the hatch on both sides, making it easier to exit the hatch while clamping and compressing it. The clamping arm plates 132 are configured to cooperate with the side walls of the machine housing, forming surface compression of the internal material. The rotary shaft arm assemblies 31 are integrated with the hatch on both sides of the transverse outlet, reducing the number of components in the machine housing baling area, reducing the transverse dimensions of the machine housing baling area, and making the structure more compact.

[0039] The pivot arm assembly 131 includes a vertically arranged pivot 3101 and several pivot arms 3102 arranged axially on the pivot 3101. The pivot 3101 is rotatably arranged on the left and right sides of the transverse outlet of the chassis 1. An arm plate 137 is fixedly mounted on the upper part of the pivot 3101. The longitudinal drive component 133 is a telescopic cylinder, and both ends of the telescopic cylinder are hinged to the arm plate 137. The pivot arms 3102 are correspondingly arranged with the clamping arm plate 132. The corresponding arrangement means that the pivot arm is in contact with the clamping arm plate but not connected when the clamping arm plate is in its initial position. Two crank arms form a group, with the two crank arms in the same group corresponding to the two rear support plates at the same height. During compression, the telescopic cylinder extends, driving the rotating shaft and crank arms to rotate forward. The crank arms contact and press against the rear support plates, pushing the clamping arm plates towards the inside of the machine casing to compress the material in the packaging area. After compaction and packaging, the telescopic cylinder retracts, driving the rotating shaft and crank arms to rotate in the opposite direction, and the crank arms disengage from the rear support plates. During the process of the transverse pusher pushing the material, the pusher plate of the transverse pusher pushes the clamping arm plates back to their original position. The longitudinal drive component can also be a cylinder, and the drive component that provides the left and right swinging power for the clamping arm plates belongs to the same inventive concept as the telescopic cylinder of this utility model. The front panels of several clamping arm plates are located in the same plane to perform planar contact compression of the material, ensuring the quality of compression and packaging.

[0040] In addition, such as Figure 9As shown, it should be noted that the chassis also includes conventional components such as a hydraulic pump station 10 to ensure the normal operation of the equipment. A rope hook unit module 8 can also be installed on the side wall of chassis 1 corresponding to the packing area. The rope hook unit module 8 can be detachably connected to the chassis as an independent installation module, facilitating assembly and transportation. The rope hook unit module 8 includes a box-shaped frame 81, which is detachably connected to chassis 1. The top of the box-shaped frame 81 is equipped with a lifting ring for easy lifting and installation. The rope hook is a smooth rod with a pointed tip, and the pointed tip has a hook groove for hooking and binding rope. Rope hooks 83 are correspondingly arranged with wire grooves 11 on chassis 1, and the number of rope hooks 83 corresponds one-to-one with the number of wire grooves 11. The longitudinal sliding frame 82, under the action of the longitudinal telescopic drive component 84, drives the rope hooks 83 to move relative to chassis 1. The longitudinal telescopic drive component 84 can be an existing hydraulic cylinder or pneumatic cylinder, or it can be a structure of a motor plus a sprocket and chain. Specifically, a small sprocket is set at the front of the box-shaped frame, and a motor is set at the rear of the frame. A large sprocket is set on the motor, and a chain is set between the small sprocket and the large sprocket. The longitudinal sliding frame is connected to the chain. The movement of the chain drives the longitudinal sliding frame to move longitudinally, thus determining whether the rope hook is inserted into the machine box. When the rope hook is inserted into the machine box, it pulls the binding rope on the opposite side of the machine box to that side for easy knotting.

[0041] This utility model's double-head baling machine features a bidirectional pusher capable of pushing materials in both forward and backward directions. Through the cooperation of the bidirectional pusher with dual feed hoppers, dual baling zones, and two lateral discharge ports, it can simultaneously bale two types of materials and push them out of the hopper synchronously or asynchronously, improving both baling and discharge efficiency. This double-head baling machine integrates two baling devices, making full use of production space while significantly increasing production capacity and reducing production costs, thus meeting market demands.
