Description

Technical Field

[0001] This utility model relates to the technical field of waste material compression equipment, and in particular to a pre-compressible vertical hydraulic baler. Background Technology

[0002] Currently available vertical hydraulic balers lack pre-compression devices. When baling bulky waste materials like plastic film, workers must manually place the loose film into the compression chamber. Due to the large volume of the waste, a small portion of the film fills the chamber without reaching the desired weight. Therefore, workers often need to use the hydraulic press head to compress this portion of film before adding more, repeating this process multiple times until the desired weight is achieved. This repetitive operation not only reduces baling efficiency but also increases the workload, being both time-consuming and labor-intensive.

[0003] In view of this, the present invention provides a new solution to the above problems. Utility Model Content

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example: A pre-compressible vertical hydraulic baler, such as Figure 1-4 As shown, the machine includes a body 1, a pre-compression mechanism 8, a weighing mechanism 6, a control mechanism, and a pressing mechanism 2 mounted on the body 1. The body 1 contains a pressing chamber 9. The pressing mechanism 2 is used to compress the material within the pressing chamber 9. The pressing mechanism 2 includes a hydraulic press 21 and a hydraulic press head. The hydraulic press 21 drives the hydraulic press head to move up and down, thereby compressing waste materials such as plastic film through the hydraulic press head. The hydraulic press 21 is existing technology, so its specific structure and working principle will not be described in detail here. Specifically, the hydraulic press head is bolted to the lower end of the hydraulic telescopic head of the hydraulic press 21. The hydraulic press head includes an extrusion plate 221 and a base plate 222. The extrusion plate 221 is located above the pressing chamber 9 and welded to the bottom surface of the base plate 222. The hydraulic press 21 drives the base plate 222 to move up and down, so that the extrusion plate 221 can compress waste materials such as plastic film through the extrusion plate 221. The extrusion plate 221 directly contacts the material to generate pressure.

[0030] Preferably, a protective door and a bolt 5 are provided on one side of the machine body 1. The protective door includes a first protective door 41 and a second protective door 42 located below the first protective door 41. The first protective door 41 and the second protective door 42 are respectively locked to the machine body 1 by the bolt 5. The first protective door 41 and the second protective door 42 are provided mainly to open the pressing chamber 9 so as to facilitate the removal of the compressed material.

[0031] In the above technical solution, the double-door structure divides the pressing chamber 9 into upper and lower independent sealed areas, which can effectively prevent material splashing and provides better safety compared to the traditional single-door structure. During pressing, only the hydraulic press 21 needs to be driven to move the base plate 222 and the extrusion plate 221 downward, thereby compressing the loose material. The pressing mechanism 2 uses a hydraulic telescopic head to drive the vertical movement of the extrusion plate 221, and the rigid connection between the base plate 222 and the hydraulic press 21 achieves efficient force transmission.

[0032] Reference Figure 1-4 The machine body 1 has a feed inlet 7 on one side, and a pre-compression mechanism 8 is located at the feed inlet 7 and is used to pre-compress the material to be compressed. Preferably, the feed inlet 7 is located on the upper side of the machine body 1, and the feed inlet 7 and the protective door are located on adjacent sides of the machine body 1, respectively.

[0033] Preferably, the pre-compression mechanism 8 includes a motor 81, a first roller 84, and a second roller 85. The motor 81 is mounted on the outside of the machine body 1 and is used to drive the first roller 84 to rotate around its central axis. The first roller 84 and the second roller 85 are arranged in parallel and have a gap in between for material to pass through.

[0034] Specifically, both the first roller 84 and the second roller 85 are horizontally arranged, with the first roller 84 located above the second roller 85.

[0035] Preferably, the first roller 84 and the second roller 85 are both located at the feed inlet 7, and the second roller 85 is rotatably connected to the machine body 1.

[0036] Specifically, the output shaft of motor 81 is rigidly connected to the drive end shaft of the first roller 84 through a flexible coupling 82. The non-drive end shaft of the first roller 84 is mounted on the side wall of the feed inlet 7 of the machine body 1 through a bearing 83. Both ends of the second roller 85 are mounted on the side wall of the feed inlet 7 of the machine body 1 through bearings 83.

[0037] In the above technical solution, the two rollers (first roller 84 on top, second roller 85 on the bottom) are arranged horizontally to form a progressive extrusion channel. When the material passes through the gap, it is subjected to bidirectional shear force (first roller 84 actively applies pressure, second roller 85 passively rubs in the opposite direction), increasing the density of the loose material by 50%-65%, thus achieving a pre-compression effect. The flexible coupling 82 compensates for the radial deviation between the motor 81 and the shaft of the first roller 84, ensuring power transmission. The non-drive end of the first roller 84 is fixed by a deep groove ball bearing 83, and both ends of the second roller 85 are respectively equipped with deep groove ball bearings 83. The dual bearing 83 system can withstand the roller assembly.

[0038] Preferably, the gap between the first roller 84 and the second roller 85 is 5-20mm.

[0039] Preferably, both the circumferential surfaces of the first roller 84 and the second roller 85 are provided with threads.

[0040] In the above technical solution, the threaded grooves of the double rollers form a spiral guiding channel, which forces the material (plastic film, fiber, etc.) to be propelled within the gap, thus improving conveying efficiency. The threaded tooth shape can guide the material to be compacted in layers within the gap, improving compression uniformity.

[0041] Specifically, the threads on the circumferential surfaces of the first roller 84 and the second roller 85 can be designed with reverse threads to facilitate the generation of bidirectional shear force.

[0042] Reference Figure 1-4 The weighing mechanism 6 is located at the bottom of the pressing chamber 9 and is used to weigh the material inside the pressing chamber 9. The weighing mechanism 6 includes a hydraulic oil pump 61, a hydraulic oil input pipe 62, and a weighing component. The weighing component includes a support plate 631, a hydraulic lifter 632, and a weighing sensor 633. The support plate 631 is located at the bottom of the pressing chamber 9. The hydraulic lifter 632 is located below the support plate 631 and is used to drive the support plate 631 to move up and down. The weighing sensor 633 is located below the support plate 631 and between the hydraulic lifter 632 and the support plate 631. The hydraulic lifter 632 is connected to the hydraulic oil pump 61 through the hydraulic oil input pipe 62. The hydraulic oil pump 61 is located on the outside of the machine body 1.

[0043] Preferably, a pressure plate 10 is provided at the bottom of the pressing chamber 9, and the pressure plate 10 is used to support the material in the pressing chamber 9.

[0044] Preferably, multiple weighing components are provided.

[0045] Specifically, there are two weighing components. The two weighing components are located on both sides of the bottom of the pressing chamber 9.

[0046] In the above technical solution, during weighing, the hydraulic oil pump 61 is activated to move the support plate 631 upward via the hydraulic lifter 632, so that the material in the pressing chamber 9 is detached from the pressure plate 10. At this time, the material in the pressing chamber 9 is supported on the support plate 631. The pressure plate 10 bears the material during non-weighing stages, dispersing stress concentration at the bottom of the chamber, reducing the risk of long-term deformation of the support plate 631, and extending its service life. To avoid the weighing component being repeatedly weighed by the hydraulic press head, which would affect the weighing accuracy, the support plate 631 is lowered below the pressure plate 10 via the hydraulic system during compression, protecting the weighing component from damage due to overload. The weighing process mainly uses a gravity sensor to sense the waste plastic film in the pressing chamber 9. When the weight of the waste plastic film reaches the preset weight, an automatic alarm is triggered, and the operator stops adding waste plastic film.

[0047] Preferably, the control mechanism includes a display screen 31, a controller 32, function buttons 33, and an emergency stop button 34. The controller 32 is electrically connected to the display screen 31, the load cell 633, the hydraulic press 21, and the motor 81. The load cell 633 detects the weight of the material in the pressing chamber 9 and sends this weight information to the controller 32. The display screen 31 displays the weight of the material and other necessary information. The function buttons 33 (such as calibration and unit switching) are connected to the controller 32 via a GPIO digital input interface, supporting interrupt-triggered mode with a response time of <10ms.

[0048] Preferably, the control mechanism may also include a buzzer, which is electrically connected to the controller 32. When the weight of the waste plastic film reaches the preset weight, an automatic alarm can be triggered.

[0049] In the above technical solution, the weighing sensor 633 detects the weight information of the material in the pressing chamber 9 and transmits it to the controller 32. The display screen 31 refreshes the weight data in real time, improving the intuitiveness of human-machine interaction. The emergency stop button 34 is directly connected to the safety circuit of the controller 32, and immediately cuts off the power to the hydraulic oil pump 61 when triggered. The controller 32 can set the speed of the motor 81, set the pre-compression weight, and control the lifting and lowering of the hydraulic press head, realizing centralized control of business functions.

[0050] Working Principle: Workers place waste film and other waste materials into the feed inlet 7. Driven by motor 81, the first roller 84 rolls the plastic film into the gap between the first roller 84 and the second roller 85, compressing the film into a flat block shape. This significantly reduces the volume of the waste film before it is fed into the pressing chamber 9. The weighing sensor 633 automatically rises under the action of the hydraulic system to detect the weight of the waste plastic film, and the detected data is displayed on the control screen 31. When the hydraulic press head is pressing down on the plastic film, the support plate 631 can be automatically lowered below the pressure plate 10 under worker control to prevent excessive pressure and damage to the sensitivity of the weighing sensor 633. When the film reaches a certain weight, the worker presses the stop button on motor 81 to prevent accidental injury during the operation of the pressing chamber 9. As the hydraulic press head slowly descends, the film in the pressing chamber 9 is compressed into a smaller block shape, which is then removed.

[0051] In summary, this invention, by adding a pre-compression mechanism 8, can quickly compress loose plastic film into small pieces, thus pre-compressing its volume before it enters the pressing chamber 9. This allows the chamber to hold more plastic film, eliminating the need for repeated compression by the hydraulic press head, improving work efficiency, reducing the workload of workers, and saving time and effort. Furthermore, the weighing mechanism 6 allows for weight detection of the baled waste material during compression, effectively controlling the weight of the baled waste blocks and reducing the need for subsequent weighing, thereby streamlining the workflow and improving efficiency.

[0052] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
