Description

Technical Field

[0001] This utility model relates to the field of metal baling machine technology, specifically a lubrication and compression system for a single-discharge baling machine. Background Technology

[0002] Metal balers, as core equipment in the field of scrap metal recycling, significantly improve material transportation efficiency and storage density, and reduce logistics costs by compressing and baling loose metal materials. The lubrication and compression system, a key functional module of single-discharge balers, directly determines the equipment's operational stability, compression efficiency, and the lifespan of its core components. In practical industrial applications, single-discharge balers operate under high-frequency, high-load conditions for extended periods. Their lubrication and compression systems must simultaneously meet the dual requirements of precise lubrication and efficient compression. Defects in the system design can easily lead to a series of problems.

[0003] In existing technologies, most single-discharge balers have several shortcomings in their lubrication and compression systems: First, some systems have simple heat dissipation structures, relying solely on natural cooling, which makes it difficult to quickly dissipate the large amount of heat generated by the hydraulic system during continuous operation, leading to increased oil temperature, decreased hydraulic oil viscosity, and affecting the stable output of compression force; Second, the oil circuit layout of some lubrication systems is not optimized enough, and key moving parts such as the cylinders and mold sleeves of the transverse opening mechanism are prone to uneven lubrication, which exacerbates component wear; Third, some systems lack a complete air filtration and liquid level monitoring mechanism, making the hydraulic oil susceptible to contamination by external impurities or failure to replenish in time due to low liquid levels, shortening the service life of hydraulic components and increasing equipment maintenance costs and downtime.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a lubrication and compression system for a single-output baler, which has the following beneficial effects:

[0015] 1. The lubrication and compression system of this single-discharge baler ensures uniform lubrication of key moving parts through optimized and improved oil circuit layout. The addition of a comprehensive air filtration device and liquid level monitoring mechanism ensures continuous and precise delivery of lubricating oil to the discharge end of the main pressure mechanism, effectively reducing frictional resistance between the material and the inner wall of the discharge port, lowering the wear rate of components, extending the service life of core components such as the main pressure head and die sleeve, and reducing equipment maintenance frequency and costs. The air filter on the top of the oil tank effectively filters dust and impurities from the air entering the tank, preventing hydraulic oil contamination and ensuring the cleanliness of the hydraulic system oil. The liquid level gauge on the outer wall provides real-time and intuitive display of the hydraulic oil level in the tank, facilitating timely replenishment of hydraulic oil by operators, preventing damage to the hydraulic pump due to low liquid level, and improving system operational stability.

[0016] 2. By setting up a pre-compression mechanism and a transverse door opening mechanism to work together, the pre-compression cylinder drives the pre-compression head to pre-compress the material, which can make the material initially compacted and formed before the main pressing process, reducing the problem of material loosening and displacement during the main pressing process, and significantly improving the compactness and regularity of the packaged product; at the same time, the mold sleeve of the transverse door opening mechanism is made of high-strength cuboid mold steel, and the internal material through hole design is adapted to the shape of the packaged material, so the material discharge process is smooth and unobstructed, effectively reducing the failure rate of material jamming and greatly improving the overall packaging efficiency.

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.

[0023] Please see Figure 1-4 This utility model provides a lubrication and compression system for a single-discharge baler, including a base 1. The base 1 adopts an integral welded structure, which has high rigidity and stability. A main pressure mechanism 2 is installed on the upper left side of the base 1, and the main pressure mechanism 2 is fixedly connected to the base 1 by bolts. A pre-compression mechanism 3 is installed above the main pressure mechanism 2. A transverse opening mechanism 4 is installed on one side of the main pressure mechanism 2 for material discharge and mold opening and closing. A hydraulic station 5 is also installed on the right side of the base 1 to provide power support for the entire system.

[0024] The hydraulic station 5 includes an oil tank 501 mounted on the base 1. The oil tank 501 is welded from carbon steel plates and has an internal rust-proof treatment. An air filter 509 is installed on the top of the oil tank 501 to filter the air entering the tank and prevent impurities from entering the hydraulic system. A level gauge 510 is installed on the outer wall of the oil tank 501 to facilitate observation of the hydraulic oil level. A multi-way directional valve 502 and a motor 503 that drives the hydraulic oil pump inside the oil tank 501 are also installed on the oil tank 501. The motor 503 is connected to the hydraulic oil pump via a coupling. The outlet of the internal hydraulic oil pump is connected to the inlet of the multi-way directional valve 502 via a high-pressure oil pipe. The multi-way directional valve 502 has multiple oil outlet lines, including a first oil line 504 connected to the main pressure mechanism 2, a second oil line 505 connected to the pre-pressure mechanism 3, and a third oil line 506 connected to the transverse opening mechanism 4.

[0025] The hydraulic station 5 also includes a lubrication pump 507 installed on the side of the pre-pressing mechanism 3. The lubrication pump 507 is fixed by a bracket, and its oil outlet is connected to the discharge end of the main pressure mechanism 2 through a fourth oil line 508. This is used to periodically lubricate the discharge part of the main pressure mechanism 2 and reduce wear. A liquid cooler 6 is installed on the rear side of the base 1 and on the rear side of the oil tank 501. The multi-way directional valve 502 is also equipped with a fifth oil line 511 connected to the liquid cooler 6. The liquid cooler 6 is connected to the oil tank 501 through a sixth oil line 512, forming a complete hydraulic oil cooling circulation loop to effectively control the system oil temperature.

[0026] In the above embodiment, the main pressure mechanism 2 includes a main pressure cylinder 201 and a main pressure head 202. The cylinder body of the main pressure cylinder 201 is fixedly connected to the left end face of the base 1 via a flange. The piston rod end of the main pressure cylinder 201 is detachably connected to the main pressure head 202 via a threaded connection or a quick-connect coupling. The main pressure head 202 is made of high-strength alloy steel, and a discharge port 203 is provided on the outer side of the corresponding main pressure mechanism 2 for discharging the formed material.

[0027] The pre-compression mechanism 3 includes a hopper 301, a pre-compression chamber 302, and a pre-compression cylinder 303. The hopper 301 is mounted on the base 1 via four support legs 304. The pre-compression chamber 302 is vertically mounted above the main compression mechanism 2 and is fixedly connected to the main compression mechanism 2 by bolts. The pre-compression cylinder 303 is mounted on the top of the pre-compression chamber 302. A pre-compression head 305 is mounted on the end of the piston rod of the pre-compression cylinder 303. The lower end of the pre-compression head 305 can press downwards into the main compression mechanism 2 to achieve pre-compression of the material. The discharge port of the hopper 301 and the inlet of the pre-compression chamber 302 are connected via a chute or flexible connection.

[0028] The horizontal door opening mechanism 4 includes a door opening cylinder 401. The cylinder body of the door opening cylinder 401 is fixed to the side of the main pressure mechanism 2, and a mold sleeve 402 is installed on its piston rod. The mold sleeve 402 is made of high-strength cuboid mold steel and has been hardened, giving it high wear resistance. A through-hole 403 is provided inside the mold sleeve 402 for material forming and guiding.

[0029] The working principle of the above embodiments is as follows:

[0030] In operation, the scrap metal is first placed into the hopper 301, where it is agitated by the internal stirring mechanism and then broken up and broken by the internal feeding auger mechanism, orderly entering the pre-pressing hopper 302 from the bottom outlet of the hopper 301. Then, the pre-pressing cylinder 303 is activated, its piston rod driving the pre-pressing head 305 downwards to press the scrap metal into the main pressing mechanism 2. Next, the main pressing cylinder 201 is activated, its piston rod driving the main pressing head 202 to continue pushing the scrap metal onto the solid surface behind the material passage 403 of the die sleeve 402. After compaction, the piston rod drives the main pressure head 202 to retract, and the compacted metal scrap forms a cake shape. Then, the opening cylinder 401 of the transverse opening mechanism 4 drives the mold sleeve 402 to move forward, aligning the material through hole 403 of the mold sleeve 402 with the discharge port 203. The retracted main pressure head 202 then pushes forward again, pushing the cake-shaped metal scrap from the material through hole 403 out of the discharge port 203 into the guide rail 7, completing one baling operation. The anti-reverse mechanism 8 installed on the discharge port can prevent the cake from retracting. An electrical control box 9 is also installed on the base 1 to supply power to the entire baler.

[0031] Throughout the entire operation, each hydraulic circuit achieves precise drive of key cylinders through the directional transmission and pressure regulation of hydraulic oil: the second hydraulic circuit 505 controlling the pre-pressing cylinder 303 inputs hydraulic oil to push the piston rod out, driving the pre-pressing head 305 downward to press the metal scrap into the main pressing mechanism 2; the first hydraulic circuit 504 controlling the main pressing cylinder 201 inputs hydraulic oil to achieve the reciprocating action of the piston rod extending (driving the main pressing head 202 to advance and compact the material) and retracting (driving the main pressing head back to the initial position); the third hydraulic circuit 506 controlling the opening cylinder 401 inputs hydraulic oil to push the piston rod out, driving the mold sleeve 402 to move forward and backward, and when the material through hole 403 is aligned with the discharge port 203, the cake is pushed out; each hydraulic circuit can be used with components such as overflow valves and throttle valves to ensure stable cylinder action pressure and controllable flow, ensuring the sequence and accuracy of each step.

[0032] In addition, the lubrication pump 507 provides continuous lubrication to the moving parts in the main compression and discharge process through the fourth oil line 508: During the main compression stage, when the main pressure head 202 reciprocates along the main pressure mechanism 2, the lubrication pump delivers lubricating oil to the mating surface between the main pressure head 202 and the die sleeve 402 to reduce metal friction and prevent damage to the parts due to dry friction. When the cake is discharged, lubricating oil is injected when the die sleeve 402 slides along the frame guide rail, which can reduce the moving resistance and ensure that the die sleeve is smoothly in place. When the main pressure head 202 pushes out the cake again, the injected lubricating oil can reduce the friction between the cake and the through hole, prevent the cake from getting stuck, and ensure the smoothness of the discharge process.
