Description

Technical Field

[0001] This disclosure relates to the field of baling equipment technology, and more specifically, to a horizontal hydraulic baler. Background Technology

[0002] Horizontal hydraulic balers are mainly used for baling loose materials such as waste paper, waste plastics, and straw. Also known as strapping machines, balers, or bundling machines, they significantly reduce volume and increase density after baling, facilitating transportation and storage. In related technologies, balers use a unidirectional compression method to compress materials, and the materials are manually removed after baling. Due to the limited internal space of the baler housing, it is difficult to manually remove the baled materials smoothly from the machine, resulting in low baling efficiency. Utility Model Content

[0003] The purpose of this disclosure is to provide a horizontal hydraulic baler that can quickly compress materials and facilitate the removal of the baled materials, thereby improving baling efficiency.

[0004] To achieve the above objectives, this disclosure provides a horizontal hydraulic baler, including a housing, a feeding assembly, and two pairs of pressing assemblies. The housing has a feeding port, and the two pairs of pressing assemblies are arranged inside the housing and located on opposite sides of the feeding port. Each pressing assembly includes a hydraulic cylinder and a pressing plate pulverizedly connected to the hydraulic cylinder. The feeding assembly includes a movable plate and a rotation drive. The movable plate is rotatably disposed at the bottom of the housing, and the rotation drive is pulverizedly connected to the movable plate to drive the movable plate to rotate and position the movable plate in a first position and a second position. In the first position, the movable plate is parallel to the bottom plate of the housing and forms a compression chamber with the two pressing plates. In the second position, the movable plate is arranged at an angle to the bottom plate, and the lower end of the movable plate overlaps the feeding port.

[0005] Optionally, the movable plate includes a plate body and a plurality of rollers rotatably disposed on the top surface of the plate body. The plurality of rollers are spaced apart to form a roller conveyor chain, and two extrusion plates are located above the roller conveyor chain and form the compression cavity between the extrusion plates and the roller conveyor chain.

[0006] Optionally, each of the pressing assemblies includes at least two hydraulic cylinders arranged in parallel, and the pressing plate is slidably connected to the side plate of the housing along the extension and retraction direction of the hydraulic cylinders.

[0007] Optionally, the bottom plate of the box is provided with a U-shaped seat, the U-shaped seat includes two connected side arms and a groove between the two side arms, the bottom of the movable plate is fixedly provided with a connector, the bottom end of the connector is rotatably connected to the two sides of the groove through a rotating shaft, and the opposite ends of the two side arms extend to abut against the corresponding side plates of the box.

[0008] Optionally, the housing is further provided with a buffer and shock absorption assembly, which is located on opposite sides of the rotating shaft and is used to elastically abut against the lower end when the movable plate is in the second position.

[0009] Optionally, the buffer and shock absorption assembly includes a frame and a pressure column. The frame is fixed inside the box and has an upper plate and a lower plate spaced apart. The pressure column slides through the upper plate. The frame is provided with an elastic element that abuts against the pressure column, so that the pressure column can elastically abut against the lower end through the elastic element.

[0010] Optionally, the buffer and shock absorption assembly further includes an adjusting stud, which is threaded through the lower plate, and the elastic element is provided between one end of the adjusting stud located in the frame and the pressing post, and a knob is provided at the other end of the adjusting stud.

[0013] Optionally, the horizontal hydraulic baler further includes a door and a lifting mechanism. The door is slidably disposed at the feeding port, and the lifting mechanism is throttle-connected to the door to open or close the feeding port.

[0014] Through the above technical solution, the horizontal hydraulic baler disclosed herein is equipped with two pairs of pressing components, which are located on opposite sides of the feeding port to achieve bidirectional extrusion of the material, making the material more evenly stressed, significantly increasing the material compression density, and improving the material compression efficiency. The movable plate of the feeding component can switch between a first position and a second position. In the first position, the movable plate is parallel to the bottom plate of the box and forms a closed compression chamber with the extrusion plate to ensure that the material does not leak during the compression process, thus improving the compression efficiency.

[0022] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0023] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component, and "top" and "bottom" refer to "top" and "bottom" along the height direction in the usage state of this disclosure. Furthermore, the terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance implications. In the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0024] According to exemplary embodiments of this disclosure, reference is made to Figures 1 to 3 As shown, a horizontal hydraulic baler is provided, including a housing 1, a feeding assembly 2, and two pairs of pressing assemblies 3. The housing 1 has a feeding port 10, and the two pairs of pressing assemblies 3 are arranged inside the housing 1 and are located on opposite sides of the feeding port 10. The pressing assembly 3 includes a hydraulic cylinder 31 and a pressing plate 32 that is pulverizedly connected to the hydraulic cylinder 31. The feeding assembly 2 includes a movable plate 21 and a rotation drive 22. The movable plate 21 is rotatably disposed at the bottom of the housing 1, and the rotation drive 22 is pulverizedly connected to the movable plate 21 to drive the movable plate 21 to rotate and to place the movable plate 21 in a first position and a second position. In the first position, the movable plate 21 is parallel to the bottom plate of the housing 1 and forms a compression cavity 20 with the two pressing plates 32. In the second position, the movable plate 21 is arranged at an angle to the bottom plate, and the lower end 211 of the movable plate 21 overlaps the feeding port 10.

[0025] Through the above technical solution, in the horizontal hydraulic baler disclosed herein, two pairs of pressing components 3 are set, and the two pairs of pressing components 3 are respectively located on opposite sides of the feeding port 10, realizing bidirectional extrusion of the material, making the material more uniformly stressed, significantly improving the material compression density, and improving the material compression efficiency; the movable plate 21 of the feeding component 2 can switch between a first position and a second position. In the first position, the movable plate 21 is parallel to the bottom plate of the box 1 and forms a closed compression chamber 20 with the extrusion plate 32, ensuring that the material will not leak during the compression process and improving the compression efficiency; in the second position, the movable plate 21 is tilted to the lower end 211 to overlap the feeding port 10, forming a material sliding channel, so that the baled material can automatically slide down by gravity without manual intervention, reducing labor intensity, and avoiding safety risks that may be caused by manual operation, such as pinching and collision. In summary, this application improves the overall baling efficiency and improves the convenience of operation by adopting bidirectional extrusion and automatic discharge.

[0026] In this disclosure, reference is made to Figure 2 As shown, a support base 13 is provided on the bottom plate of the box 1. The support base 13 supports the end of the movable plate 21 away from the feed port 10. The rotation drive 22 can be set as a hydraulic cylinder. One end of the rotation drive 22 is connected to the support base 13, and the other end is rotatably connected to the movable plate 21. When the rotation drive 22 is activated and extended, it pushes the movable plate 21 and puts the movable plate 21 in the second position, that is, the movable plate 21 is in an inclined state relative to the bottom plate. Conversely, when the rotation drive 22 retracts, it pulls the movable plate 21 and puts the movable plate 21 in the first position, so that the movable plate 21 is parallel to the bottom plate.

[0027] According to exemplary embodiments of this disclosure, reference is made to Figures 1 to 3 As shown, the movable plate 21 may include a plate body and multiple rollers 210 rotatably mounted on the top surface of the plate body. The multiple rollers 210 are arranged at intervals to form a roller conveyor chain. Two extrusion plates 32 are located above the roller conveyor chain and form a compression chamber 20 between the roller conveyor chain and the roller conveyor chain. In the above technical solution, by setting up a roller conveyor chain, the friction between the material and the movable plate 21 is reduced, allowing the material to reach the feed port 10 more smoothly when the movable plate 21 rotates to the second position. In addition, during the compression process, the rotation of the rollers 210 can also help the material better adapt to the extrusion of the extrusion plates 32, further improving the compression effect.

[0028] According to exemplary embodiments of this disclosure, reference is made to Figure 1 As shown, each pressing assembly 3 may include at least two hydraulic cylinders 31 arranged in parallel, and the extrusion plate 32 is slidably connected to the side plate of the housing 1 along the extension and retraction direction of the hydraulic cylinders 31. Using at least two parallel hydraulic cylinders 31 provides a more stable and greater extrusion force to the extrusion plate 32. For example, when compressing dense straw, the coordinated operation of multiple hydraulic cylinders 31 ensures that the extrusion plate 32 is subjected to uniform force during the extrusion process, preventing tilting of the extrusion plate 32 due to uneven force, which would affect the compression effect. Simultaneously, the slidable connection of the extrusion plate 32 to the side plate of the housing 1 along the extension and retraction direction of the hydraulic cylinders 31 ensures the stability and accuracy of the movement of the extrusion plate 32, making the compression process more reliable. According to an exemplary embodiment of this disclosure, refer to... Figures 1 to 3As shown, a U-shaped seat 4 can be provided on the bottom plate of the box 1. The U-shaped seat 4 includes two connected side arms and a groove 40 located between the two side arms. A connector is fixedly provided at the bottom of the movable plate 21. The bottom end of the connector is rotatably connected to the two sides of the groove 40 through a rotating shaft 5. The opposite ends of the two side arms extend to abut against the corresponding side plates of the box 1. The U-shaped seat 4 provides a stable rotational support structure for the movable plate 21. The rotating shaft 5 rotatably connects the movable plate 21 to the groove 40 of the U-shaped seat 4, allowing the movable plate 21 to rotate stably around the rotating shaft 5, realizing the switching between the first position and the second position. The abutment of the side arms of the U-shaped seat 4 against the side plates of the box 1 further enhances the stability of the entire structure, ensuring that the movable plate 21 will not shake or shift during rotation, thus ensuring the normal operation of the packing machine.

[0029] According to exemplary embodiments of this disclosure, reference is made to Figures 1 to 3 As shown, the housing 1 may also be equipped with a buffer and shock absorption assembly 6. The buffer and shock absorption assembly 6 and the rotation drive component 22 are located on opposite sides of the rotating shaft 5, and are used to elastically abut against the lower end 211 when the movable plate 21 is in the second position. When the movable plate 21 rotates from the first position to the second position, the buffer and shock absorption assembly 6 can buffer and absorb the lower end 211 of the movable plate 21, reduce the impact force when the movable plate 21 rotates to the position, reduce noise, and at the same time protect the structure of the movable plate 21 and the housing 1, thus extending the service life of this horizontal hydraulic baler.

[0030] According to exemplary embodiments of this disclosure, reference is made to Figure 4 As shown, the buffer and shock absorption assembly 6 may include a frame 61 and a pressure post 62. The frame 61 is fixed inside the housing 1 and has an upper plate and a lower plate spaced apart. The pressure post 62 slides through the upper plate. The frame 61 is provided with an elastic element 63 that abuts against the pressure post 62, allowing the pressure post 62 to elastically abut against the lower end 211. Specifically, the elastic element 63 undergoes elastic deformation when the pressure post 62 contacts the lower end 211 of the movable plate 21, absorbing the impact force brought by the rotation of the movable plate 21 and achieving the function of buffering and shock absorption. For example, when the movable plate 21 rotates rapidly to the second position, the pressure post 62 is subjected to pressure from the lower end 211, and the elastic element 63 is compressed, converting the impact force into elastic potential energy, thereby reducing the impact on the equipment. The elastic element 63 may be provided with a spring or an elastic rubber sleeve.

[0031] According to exemplary embodiments of this disclosure, reference is made to Figure 4As shown, the buffer and shock-absorbing assembly 6 may further include an adjusting stud 64, which is threaded through the lower plate. One end of the adjusting stud 64, located within the frame 61, is fitted with an elastic element 63 between it and the pressure post 62. The other end of the adjusting stud 64 is fitted with a knob 65. By adjusting the stud 64 and the knob 65, the compression degree of the elastic element 63 can be adjusted according to actual working requirements, thereby adjusting the buffering force of the buffer and shock-absorbing assembly 6. For example, when baling materials of different weights or volumes, the adjusting stud 64 can be adjusted by rotating the knob 65 to change the compression amount of the elastic element 63, allowing the buffer and shock-absorbing assembly 6 to adapt to different working conditions and ensuring the stable operation of this horizontal hydraulic baler.

[0032] According to exemplary embodiments of this disclosure, reference is made to Figure 1 As shown, there can be two buffer and shock-absorbing components 6, with the two buffer and shock-absorbing components 6 located on both sides of the feed port 10. This arrangement can more evenly buffer and dampen the movable plate 21, further improving the buffering effect. For example, during the rotation of the movable plate 21, the buffer and shock-absorbing components 6 on both sides work simultaneously, which can effectively prevent the movable plate 21 from tilting or shifting, ensuring that the movable plate 21 is stably in the second position, facilitating the smooth discharge of materials.

[0033] According to exemplary embodiments of this disclosure, reference is made to Figure 1 As shown, the housing 1 includes a top cover 11, on which a hopper 12 is mounted, and on which a vibrator 7 is mounted. The hopper 12 facilitates the feeding of materials, while the vibrator 7 ensures that the materials are more evenly distributed before entering the compression chamber 20, preventing material accumulation. For example, when feeding waste paper, the vibrator 7 can shake the waste paper apart, making it fill the compression chamber 20 more tightly, thus improving compression efficiency and quality.

[0034] According to exemplary embodiments of this disclosure, reference is made to Figures 1 to 3 As shown, the horizontal hydraulic baler also includes a gate 8 and a lifting mechanism 9. The gate 8 is slidably positioned at the feeding port 10, and the lifting mechanism 9 is connected to the gate 8 to open or close the feeding port 10. The gate 8 and lifting mechanism 9 are designed to close the feeding port 10 during material compression, preventing material from overflowing and ensuring the smooth operation of the compression process. Figure 2 As shown in the diagram; after the materials are packaged, the door 8 is raised by the lifting mechanism 9, opening the feeding port 10 to facilitate the smooth removal of materials from the feeding port 10, as shown. Figure 3 The state shown.

[0035] In this disclosure, the lifting mechanism 9 can be configured as a lead screw 91 and nut mechanism. Specifically, the lifting mechanism 9 includes a lead screw 91, a slider 92, a motor 93, and a guide rod 94. The lead screw 91 is rotatably disposed on the side of the housing 1 near the feeding port 10. The slider 92 is slidably disposed on the housing 1 and threadedly connected to the lead screw 91. The door 8 is fixedly connected to the slider 92. The guide rod 94 is parallel to the lead screw 91 and guides the door 8. When the motor 93 is started, the lead screw 91 is driven to rotate. The lead screw 91 drives the slider 92 and the door 8 to move up and down, so that the feeding port 10 opens or closes.

[0036] It should be noted that the top cover 11 can be rotatably mounted on the side plate of the box 1 and can be opened or closed. In this way, by opening the top cover 11, the packing bag for packaging can be placed inside the compression chamber 20, which improves the convenience of operation.

[0037] Reference Figures 1 to 4 The operation of the horizontal hydraulic baler disclosed herein is detailed below:

[0038] First, material is fed into the box 1 through the hopper 12 on the top cover plate 11. The vibrator 7 on the hopper 12 is activated, so that the material falls evenly into the box 1. At this time, the movable plate 21 of the feeding assembly 2 is in the first position, that is, parallel to the bottom plate of the box 1, and forms a compression chamber 20 with the two side extrusion plates 32.

[0039] Next, the hydraulic cylinders 31 of the two pairs of pressing components 3 drive the extrusion plate 32 to extrude the material bidirectionally from the opposite sides of the feeding port 10 until the set compression degree is reached.

[0040] After compression, the rotating drive 22 drives the movable plate 21 to rotate to the second position, so that it is arranged at an angle with the bottom plate, and the lower end 211 overlaps the feeding port 10. At the same time, the lifting mechanism 9 lifts the door 8 to open the feeding port 10. Under the action of gravity, the packaged material reaches the feeding port 10 along the roller conveyor chain of the movable plate 21 and slides out from the feeding port 10, completing the entire packaging process.

[0041] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
