Description

Technical Field

[0001] The utility model relates to the technical field of metal packaging, in particular to a waste aluminum packaging machine. Background Art

[0002] Aluminum alloy profiles are formed by extruding aluminum alloy rods, and then straightened and cut to length to obtain finished aluminum alloy profiles. The extrusion process forms pancake-shaped aluminum waste, and the cutting process forms rod-shaped aluminum waste. Therefore, aluminum factories generate a large amount of aluminum waste when producing aluminum profiles. Usually, a baler is used to compress the above-mentioned aluminum waste into rectangular blocks for easy transportation. The specific operation is to fill a certain amount of aluminum waste into the baler, and the top pressure plate presses the aluminum waste from top to bottom, and then the longitudinal pressure plate and the transverse pressure plate respectively squeeze the aluminum waste, and finally squeeze the aluminum waste into the space surrounded by the top pressure plate, the transverse pressure plate, the longitudinal pressure plate and the chassis. Since the top pressure plate presses the material downward in a swinging manner, and the position of the aluminum waste after being put into the chassis is irregular, the top pressure plate needs to be repeatedly pressed down to the preset position. In the prior art, the connecting rod of the piston rod of the top pressure driving cylinder passes through the mounting circular hole on the top surface of the top pressure plate, and the mounting circular hole is slightly larger than the diameter of the connecting rod to complete the smooth installation. During the use of the packaging machine, the mounting holes and the connecting rods are prone to collision and wear, which increases the noise during the operation of the packaging machine and makes the top pressure drive cylinder susceptible to damage.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Combine the following Figures 1 to 6 , describing a waste aluminum baler according to an embodiment of the utility model.

[0035] A waste aluminum baler comprises a chassis 1, a top pressing plate 2, a transverse pressing plate 3 and a longitudinal pressing plate 4, wherein the rear end of the top pressing plate 2 is rotatably connected to the inner wall of the rear side of the chassis 1, the transverse pressing plate 3 is located at the front end of the chassis 1, and the transverse pressing plate 3 and the longitudinal pressing plate 4 are both slidably matched with the inner wall of the chassis 1;

[0036] The top surface of the top pressure plate 2 is provided with a mounting plate 21 and a buffer assembly 22, and the mounting plate 21 is provided with an arc-shaped limiting hole 211;

[0037] A top pressure driving cylinder 5 is disposed at the rear end of the chassis 1 , and a mounting rod 51 is disposed at the end of the piston rod of the top pressure driving cylinder 5 . The mounting rod 51 passes through the limiting hole 211 and is connected to the buffer assembly 22 .

[0038] In the present technical solution, the piston rod of the top pressure driving cylinder 5 is connected to the top surface of the top pressure plate 2 through the mounting plate 21 and the buffer assembly 22. When the piston rod of the top pressure driving cylinder 5 is pushed or pulled, it has a buffering effect on the force applied by the mounting rod 51 to the mounting plate 21, greatly reducing the wear of the mounting rod 51 and the mounting plate 21, reducing the operating noise of the baler and increasing the service life of the top pressure driving cylinder 5; and the arc-shaped limit hole 211 cooperates with the buffer assembly 22 to provide a buffer distance for the piston rod.

[0039] After the aluminum scrap is filled into the chassis 1, the piston rod of the top pressure driving cylinder 5 extends out to make the front end of the top pressure plate 2 drop. Based on the supporting effect of the aluminum scrap in the chassis 1, the front end of the top pressure plate 2 cannot drop to the set position at one time, that is, the top pressure plate 2 cannot be completely perpendicular to the transverse pressure plate 3 and the longitudinal pressure plate 4. The top pressure driving cylinder 5 needs to pull up the top pressure plate 2 many times to make the top pressure plate 2 press down the aluminum scrap many times before it can be completely perpendicular to the transverse pressure plate 3 and the longitudinal pressure plate 4. The buffer component 22 plays a buffering role on the piston rod of the top pressure driving cylinder 5 during the process of multiple pressing of the top pressure plate 2, which greatly reduces the wear of the mounting plate 21 and the mounting rod 51, reduces the operating noise of the baler and increases the service life of the top pressure driving cylinder 5; thereafter, the longitudinal pressure plate 4 moves from the rear end toward the front end of the chassis 1 to the set position, and then the transverse pressure plate 3 moves from one side of the chassis 1 to the other side to the set position, so that the aluminum scrap can be pressed into a rectangular shape, which is convenient for stacking and transportation.

[0040] Understandable, see Figure 1 and Figure 2 , the size of the top pressing plate 2 is the same as the size of the inner cavity of the chassis 1, the height of the longitudinal pressing plate 4 and the transverse pressing plate 3 is equal to the distance between the top pressing plate 2 and the inner bottom wall of the chassis 1 after being pressed down, the length of the longitudinal pressing plate 4 is equal to the width of the inner cavity of the chassis 1, and the width of the transverse pressing plate 3 is equal to the distance between the longitudinal pressing plate 4 and the inner front wall of the chassis 1 after being in place. Exemplarily, the longitudinal pressing plate 4 and the transverse pressing plate 3 are both driven by a hydraulic cylinder. When the pressing is completed, the longitudinal pressing plate 4 and the transverse pressing plate 3 are retracted into the side wall of the chassis 1.

[0041] In one embodiment of the present invention, referring to Figure 3 and Figure 4 , a mounting plate 21 and a buffer assembly 22 form a set of connecting mechanisms 20, and the two sets of connecting mechanisms 20 are arranged in mirror symmetry; the two ends of the mounting rod 51 are arranged on the two sets of connecting mechanisms 20. The two sets of connecting mechanisms 20 simultaneously connect the two ends of the mounting rod 51, and the piston rod of the top pressure driving cylinder 5 is connected to the middle part of the mounting rod 51, thereby improving the structural stability. In another embodiment, only one set of connecting mechanisms 20 can be arranged, the middle part of the mounting rod 51 cooperates with the connecting mechanism 20, and the two ends of the mounting rod 51 are connected to the piston rod of the top pressure driving cylinder 5 through the same U-shaped connector.

[0042] Preferably, the buffer assembly 22 includes a connecting plate 221 and a spring 222, one end of the spring 222 is connected to the connecting plate 221, and the other end of the spring 222 is connected to the front end of the top pressure plate 2; the connecting plate 221 is connected to the mounting rod 51; when the spring 222 is in the original state, the mounting rod 51 is located at the center of the limiting hole 211. Therefore, when the piston rod of the top pressure driving cylinder 5 extends to make the top pressure plate 2 descend, and when the piston rod retracts to make the top pressure plate 2 rise, the buffer assembly 22 can play a buffering role. The buffer assembly 22 is composed of the connecting plate 221 and the spring 222, so that its structure is simple.

[0043] In one embodiment of the utility model, the mounting rod 51 is sleeved with a wear-resistant ring 52; the connecting plate 221 is parallel to the mounting plate 21, and the wear-resistant ring 52 is located between the mounting plate 21 and the connecting plate 221. Based on the setting of the spring 222, when the top pressure plate 2 rises or falls, there is a relative movement between the mounting plate 21 and the connecting plate 221. By setting the wear-resistant ring 52, the mounting plate 21 and the connecting plate 221 are spaced apart to reduce wear. Preferably, the wear-resistant ring 52 is fixedly sleeved on the mounting rod 51. Exemplarily, the wear-resistant ring 52 is made of plastic, or the surface of the wear-resistant ring 52 is coated with a lubricant.

[0044] Preferably, a connecting block 223 is provided at the tail end of the connecting plate 221, and the end of the spring 222 is provided on the connecting block 223, so as to facilitate the installation of the spring 222. For example, the end of the spring 222 is hooked in the connecting hole of the connecting block 223. It should be noted that the connecting block 223 is located at the end of the connecting plate 221 so that the spring 222 and the mounting plate 21 do not interfere with each other.

[0045] In one embodiment of the utility model, a counterweight block 23 is provided at the front end of the top pressure plate 2, and the front end of the mounting plate 21 and the end of the spring 222 are respectively connected to the rear end surface of the counterweight block 23; a positioning block 24 is provided at the top end of the counterweight block 23, and one end of the positioning block 24 extends out of the counterweight block 23, and the positioning block 24 is used to position the front end of the top pressure plate 2 against the top surface of the front end of the chassis 1.

[0046] By arranging a counterweight block 23 at the front end of the top pressure plate 2, the pressure of the front end of the top pressure plate 2 on the waste is increased, and the top pressure plate 2 can be quickly pressed down to a preset position. The top pressure plate 2 can reach the preset position by lifting and pressing down a small distance two to three times. When the preset position is reached, the positioning block 24 is against the top surface of the front end of the chassis 1. At this time, the bottom surface of the top pressure plate 2 is parallel to the bottom wall inside the chassis 1.

[0047] In one embodiment of the utility model, a top pressure plate 2 limiting mechanism is provided on the side of the chassis 1, and the top pressure plate 2 limiting mechanism is located below the top pressure plate 2; the top pressure plate 2 limiting mechanism is used to limit the lifting state of the top pressure plate 2.

[0048] When the top pressure plate 2 is in a raised state, the top pressure plate 2 is roughly perpendicular to the bottom wall inside the chassis 1 and is in a roughly vertical state. At this time, the top pressure plate 2 is limited by the top pressure plate 2 limiting mechanism, so that the top pressure plate 2 is in a stable raised state, thereby improving the safety of equipment use.

[0049] Preferably, the limiting mechanism of the top pressure plate 2 includes a pushing cylinder 61 and a limiting block 62 connected to each other, and the chassis 1 is provided with a receiving hole 11 for accommodating the limiting block 62; when the top pressure plate 2 is lifted, the pushing cylinder 61 is used to push the front end of the limiting block 62 from the limiting groove to the rear of the top pressure plate 2, and the front end of the limiting block 62 is abutted against the bottom end of the top pressure plate 2, and the rear end of the limiting block 62 is located in the receiving hole 11.

[0050] Based on the sliding fit between the bottom surface of the limit block 62 and the bottom wall in the chassis 1, the bottom of the chassis 1 supports the limit block 62 and the accommodating hole 11 positions the rear end of the limit block 62. When the front end of the limit block 62 is located at the rear side of the top pressure plate 2, it can prevent the top pressure plate 2 from swinging toward the front side of the chassis 1, limit the top pressure plate 2, and thus improve the safety of the device. The limit mechanism of the top pressure plate 2 has a simple structure.
