Description

Technical Field

[0001] This utility model relates to the field of chip cookie machine technology, specifically to a pressing mechanism for a chip cookie machine. Background Technology

[0002] A metal scrap briquetting machine is a mechanical device that compresses a large amount of metal scraps generated during metal processing into blocks. After the metal scraps are compressed into blocks, they can be remelted and recycled. This can significantly reduce the storage space occupied by loose metal scraps, reduce waste and environmental pollution caused by their scattering and flying during transportation, lower storage and transportation costs, and thus effectively save metal resources.

[0003] Most chip patting machines use hydraulic systems as their power source. For example, the copper chip patting machine disclosed in the utility model patent with announcement number CN214606071U uses continuous vibration of the hopper to feed the copper chips, preventing them from sticking to the hopper and falling into the mold. This type of structure uses the pressure of hydraulic oil to drive the piston rod to move back and forth or in one direction, thereby generating compression force. However, after the chip patting machine feeds the material into the pressing chamber through the screw or hopper, the chip material is piled up and distributed unevenly. When the chip material is concentrated on one side of the pressing chamber, the force between the piston rod and the chip material is uneven, which can easily lead to oil leakage problems in the hydraulic system. Utility Model Content

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0024] Example

[0025] A pressing mechanism for a chip maker includes a housing 1 and a hydraulic piston rod 2. A feed inlet is provided on the side of the housing. The hydraulic piston rod 2 reciprocates stably within the housing 1 via a guide rod 13 and a guide hole 14. A rotating cylinder 3 is coaxially mounted between the hydraulic piston rod 2 and the housing 1, and is connected to the hydraulic piston rod 2 via a bearing 4. A driven gear 5 is fixed on the rotating cylinder 3, while a drive motor 6 is synchronously slidably mounted on the hydraulic piston rod 2. Optionally, the drive motor 6 is directly fixed to the hydraulic piston rod 2 and slides synchronously with it. This motor is connected to the driven gear 5 via a reduction gearbox 7. A cap 8 is provided at the distal end of the rotating cylinder 3, forming a pressing chamber 9 together with the housing 1, and a chip-equalizing block 10 is provided within it to aid in uniform pressing.

[0026] In the optimized implementation, the end cap 8 is designed as a hemispherical structure 11 and equipped with a chip-leveling block 10 with a spiral pattern 12 to improve chip compression efficiency. Meanwhile, a combined sealing ring, consisting of an O-ring 15 and a U-ring 16, is used between the hydraulic piston rod 2 and the rotating cylinder 3 to achieve effective sealing through a concave-convex fit with the hydraulic piston rod 2.

[0027] To facilitate material discharge, a discharge port 17 is radially provided on the side of the pressing chamber 9. A discharge plate 18 is installed at the discharge port 17, and the outer side is connected to the slider 19, the discharge chute 20, and the output end of the discharge hydraulic rod 21. The discharge hydraulic rod 21 is electrically connected to the industrial control board to control the discharge action. A discharge ring 22 is fixed on the inner side of the discharge plate 18 and is connected to the stepped connection 23 of the pressing chamber 9 to ensure smooth material discharge.

[0028] Furthermore, the discharge ring 22 is hollow inside and connects to the stepped connecting surface of the receiving cavity with multiple chip suction holes 24. These chip suction holes 24 pass through the discharge ring 22 and the discharge plate 18 and are connected to the negative pressure pipe of the negative pressure device 25. The negative pressure device 25 is also electrically connected to the industrial control board and is used to suck up the debris generated during the pressing process. The negative pressure device 25 can be a fan or an air pump, and the chip suction holes 24 are set on the surface of the discharge ring 22 by threaded embedding. The negative pressure pipe is equipped with a threaded bolt joint.

[0029] Finally, to improve pressing efficiency and quality, a preferred embodiment further includes symmetrically arranging components such as the hydraulic piston rod 2 along the pressing chamber 9 to form a dual-cylinder pressing mechanism. This dual-cylinder pressing mechanism should be placed laterally, allowing pressing to be performed from both sides. All components of the entire system are electrically connected to the industrial control board for automated control and management.

[0030] The working principle of this invention is as follows: after the material is directly fed into the pressing chamber 9 from the feed inlet, the drive motor 6 serves as the power source. After starting, the power is transmitted to the driven gear 5 on the rotating cylinder 3 through the reduction gearbox 7. Since the rotating cylinder 3 and the hydraulic piston rod 2 are rotatably connected by the bearing 4, the rotating cylinder 3 will slide up and down relative to the hydraulic piston rod 2 and along the housing 1 with the hydraulic piston rod 2 under the drive of the motor. This combined sliding and rotating action is the basis of the mechanism's operation. When the hydraulic piston rod 2 slides towards the end cap 8, the space between the end cap 8 and the housing 1 (i.e., the pressing chamber 9) gradually decreases. Since the rotating cylinder 3 also rotates at the same time, the chip distribution block 10 will evenly distribute and initially compact the material entering the pressing chamber 9 during this process. As the hydraulic piston rod 2 continues to advance, the pressure on the material gradually increases, thereby achieving the pressing and shaping of the material into a chip cake. Conversely, when the hydraulic piston rod 2 slides in the opposite direction, the space inside the pressing chamber 9 increases, preparing for the next feeding and pressing of material.

[0031] During the pressing process, when the set pressing degree is reached or when discharge is required, the control board controls the discharge hydraulic rod 21 to move. The output end of the discharge hydraulic rod 21 is connected to the slider 19 on the outside of the discharge plate 18. By pushing the slider 19 to slide within the discharge chute 20, the discharge plate 18 moves outward. Due to the movement of the discharge plate 18, the chip cake originally sealed within the pressing chamber 9 is gradually exposed at the discharge port 17. At the same time, the discharge ring 22 is hollow inside and communicates with the stepped connecting surface of the receiving cavity through multiple chip suction holes 24. The negative pressure device 25 (fan or air pump) generates suction through the negative pressure pipe and the chip suction holes 24. At least one of the chip suction holes 24 passes sequentially through the discharge ring 22 and the discharge plate 18 and connects to the negative pressure pipe. This suction acts on the residual chips in the pressing chamber 9, preventing chip cake from remaining in the pressing chamber 9 and affecting the next pressing.

[0032] The guide rod 13 reciprocates through the guide hole 14, providing precise guidance for the hydraulic piston rod 2. During the sliding process of the hydraulic piston rod 2, the combination of the guide rod 13 and the guide hole 14 restricts the movement trajectory of the hydraulic piston rod 2, ensuring that it can only perform reciprocating linear motion along the axial direction of the housing 1. This prevents the hydraulic piston rod 2 from tilting or deviating due to uneven force or other factors, thereby ensuring the stability and accuracy of the pressing process. The combined sealing ring between the hydraulic piston rod 2 and the rotating cylinder 3 fits the hydraulic piston rod 2 in a concave-convex fit. During the sliding and rotation of the hydraulic piston rod 2, this sealing structure effectively prevents materials or impurities from entering the gap between the hydraulic piston rod 2 and the rotating cylinder 3, ensuring the normal operation of the mechanism and the cleanliness of the working environment.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
