Description

Technical Field

[0001] This invention belongs to the field of food packaging and processing technology, and in particular relates to a lid-removing and lid-separating mechanism suitable for the production of food packaging containers. Background Technology

[0002] In the production of food packaging containers, lids are typically sorted and arranged by sophisticated automated equipment, ultimately being neatly stacked into piles. This process not only improves production efficiency but also ensures the quality and stability of the lids, facilitating subsequent packaging and transportation. Stacked lids occupy less space in the warehouse, making them easy to manage and retrieve, while also reducing the risk of damage caused by haphazard stacking. The entire process fully reflects the modern food processing industry's strict control over details and its high regard for product quality.

[0003] When it is necessary to remove the lids, manual or robotic arms are usually used for gripping. However, manual lid separation is labor-intensive, and although robotic arms can perform simple gripping operations, the separation effect is not good when gripping a single lid because the lids are stacked, and the gripping stability is insufficient. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a cap-removing and cap-separating mechanism suitable for the production of food packaging containers.

[0005] This invention provides a cap-removing and cap-separating mechanism for producing caps suitable for food packaging containers. The mechanism includes a mounting frame on which a cap-suction assembly and a cap-clamping assembly are vertically mounted. The mounting frame is equipped with a first driving device for driving the cap-suction assembly to move up and down, and a second driving device for driving the cap-clamping assembly to move up and down. The cap-suction assembly includes a suction cup disposed at the output end of the first driving device. The cap-clamping assembly includes a clamping cylinder sleeved with the suction cup and a clamping component disposed at the bottom of the clamping cylinder. The suction cup is slidably disposed inside the clamping cylinder.

[0006] Furthermore, the clamping assembly includes a first electric telescopic rod connected to the clamping cylinder and a clamping plate disposed at the output end of the first electric telescopic rod, the clamping plate being located on the side of the first electric telescopic rod near the suction cup.

[0007] Furthermore, the mounting bracket includes a mounting plate connected to the second drive device and a mounting rod disposed above the mounting plate and connected to the first drive device.

[0008] Furthermore, the first driving device includes a second electric telescopic rod connected to the mounting rod, a connecting plate disposed at the output end of the second electric telescopic rod, and a connecting rod disposed below the connecting plate and connected to the suction cup, wherein the connecting rod is slidably connected to the mounting plate.

[0009] Furthermore, the second driving device includes a motor connected to the mounting plate and a lead screw disposed at the output end of the motor. The top end of the lead screw is connected to the motor for transmission, and the bottom end is rotatably connected to the suction cup. A connecting plate is disposed at the top of the clamping cylinder, and the lead screw passes through the connecting plate and is threadedly connected to the connecting plate.

[0010] Furthermore, a sliding groove is provided on the inner wall of the clamp, and a slider that is slidably connected to the sliding groove is provided on the side wall of the suction cup.

[0011] Furthermore, the bottom of the suction cup is provided with an annular groove into which the cover can be inserted, and the surface of the suction cup is provided with a negative pressure tube, which is connected to the annular groove.

[0012] Furthermore, a rubber pad is provided on the side of the clamp plate near the suction cup.

[0013] The technical solution provided by this invention has at least the following technical effects:

[0014] This invention discloses a cap-removing and cap-separating mechanism. When cap separation is required, a first driving device first moves the cap-suction assembly downwards, causing the suction cup of the cap-suction assembly to tightly adhere to the top cap. Then, a second driving device moves the cap-clamping assembly downwards to a predetermined position, and the clamping assembly securely holds the lower cap. Next, the first driving device is activated again, causing the suction cup to move the top cap upwards, thus completing the cap separation operation. Finally, the clamping assembly and cap-clamping device are reset. This mechanism significantly reduces manual operation intensity while ensuring good cap separation effect and high stability.

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0022] like Figure 1 As shown, this embodiment discloses a cap-removing and cap-separating mechanism for caps used in the production of food packaging containers. It includes a mounting frame on which a cap-suction assembly and a cap-clamping assembly 5 are vertically mounted. The cap-suction assembly is responsible for suctioning caps 16, while the cap-clamping assembly 5 clamps the lower cap 16 after it is suctioned, ensuring that the upper cap 16 can be smoothly separated from the lower cap 16. The mounting frame is provided with a first driving device for driving the cap-suction assembly to move up and down and a second driving device for driving the cap-clamping assembly 5 to move up and down, such as... Figure 1 As shown, the mounting bracket in this embodiment includes a mounting plate 1 connected to the second driving device, and an L-shaped mounting rod 2 mounted above the mounting plate 1 and connected to the first driving device. The mounting plate 1 is mainly used to fix the entire cap-removing and cap-splitting mechanism to the driving device. It has several mounting holes, and installation is achieved by the cooperation of bolts with the mounting holes. The driving device can be a robotic arm or other equipment to drive the movement of the entire cap-removing and cap-splitting mechanism. The cap-suction assembly includes a suction cup 4 disposed at the output end of the first driving device. The suction cup 4 can use, but is not limited to, negative pressure to suction the cap 16, such as... Figure 2 , Figure 3 As shown, an annular groove 10 is provided at the bottom of the suction cup 4 for the cover 16 to be inserted into. A negative pressure tube 11 is provided on the surface of the suction cup 4, and the negative pressure tube 11 is connected to the annular groove 10. The top of the cover 16 can be directly inserted into the annular groove 10. An air chamber 15 is also provided inside the suction cup 4, which is connected to the annular groove 10. The bottom of the air chamber 15 is connected to the negative pressure tube 11 and the bottom is connected to the annular groove 10. Several suction holes are also provided circumferentially on the surface of the annular groove 10. The negative pressure in the suction holes is used to suck up the surface of the cover 16.

[0023] The clamping assembly 5 includes a clamping cylinder 51 that is sleeved with the suction cup 4 and a clamping assembly 52 disposed at the bottom of the clamping cylinder 51. The suction cup 4 is slidably disposed inside the clamping cylinder 51. Specifically, a sliding groove 8 is provided on the inner wall of the clamping cylinder 51, and a slider 9 is provided on the side wall of the suction cup 4 that is slidably connected to the sliding groove 8. There are three sets of sliding structures between the sliding groove 8 and the slider 9, which are circumferentially distributed between the suction cup 4 and the clamping cylinder 51. Under the guiding sliding cooperation of the slider 9 and the sliding groove 8, the relative movement between the clamping cylinder 51 and the suction cup 4 is more stable.

[0024] The first driving device is mounted on the mounting rod 2. Specifically, in this embodiment, the first driving device includes a second electric telescopic rod 3 connected to the mounting rod 2, a connecting plate 13 disposed at the output end of the second electric telescopic rod 3, and a connecting rod 14 disposed below the connecting plate 13 and connected to the suction cup 4. The connecting rod 14 is slidably connected to the mounting plate 1. In this embodiment, three connecting rods 14 are arranged circumferentially, and all three connecting rods 14 move movably through the mounting plate 1. Under the guiding action of the mounting plate 1 and the connecting rods 14, the process of the second electric telescopic rod 3 driving the suction cup 4 to move up and down is more stable.

[0025] Multiple sets of clamping components 52 are arranged circumferentially at the bottom of the clamping cylinder 51. In this embodiment, three sets of clamping components 52 are provided, and these three sets of clamping components 52 are evenly distributed circumferentially at the bottom of the clamping cylinder 51. Figure 1 and Figure 2 As shown. The clamping assembly 52 includes a first electric telescopic rod 521 connected to the clamping cylinder 51 and a clamping plate 522 disposed at the output end of the first electric telescopic rod 521. The clamping plate 522 is located near the side of the first electric telescopic rod 521 near the suction cup 4. The first electric telescopic rod 521 is fixedly connected to the clamping cylinder 51, and the clamping plate 522 is arc-shaped to fit more tightly against the side wall of the cover 16.

[0026] like Figure 1 As shown, the second driving device consists of a motor 12 connected to the mounting plate 1 and a lead screw 6 installed at the output end of the motor 12. The top end of the lead screw 6 is connected to the motor 12 for transmission, and the bottom end is rotatably connected to the suction cup 4. The top of the clamp 51 is provided with a connecting plate 7, through which the lead screw 6 passes and is connected by threads. The motor 12 drives the lead screw 6 to rotate. Since the lead screw 6 and the connecting plate 7 are connected by threads, and the clamp 51 and the suction cup 4 are connected by a sliding connection, when the lead screw 6 rotates, it can drive the clamp 51 to move up and down.

[0027] Working principle: When a cap-splitting and cap-removing operation is required, the entire cap-splitting and cap-removing mechanism can be moved above the cap 16 using a drive device (e.g., Figure 4As shown, the covers 16 are stacked. Then, the second electric telescopic rod 3 is activated, causing the connecting plate 13, connecting rod 14, and suction cup 4 to move downwards together until the surface of the suction cup 4 touches the top of the uppermost cover 16 and inserts into the annular groove 10. Next, the negative pressure device is activated (this device is well known to those skilled in the art and is not described in detail in this embodiment), causing the suction cup 4 to adhere to the cover 16. Then, the motor 12 is activated, driving the lead screw 6 to rotate. The rotation of the lead screw 6 causes the clamping cylinder 51 to move downwards, moving the clamping assembly 52 at the bottom of the clamping cylinder 51 to the corresponding position. At this time, the first electric telescopic rod 521 is activated, moving the clamping plate 522 to firmly clamp the lower cover 16. The clamping plate 522 has a rubber pad on the side near the suction cup 4 to prevent wear on the cover 16 during clamping. Then, the second electric telescopic rod 3 is activated again, causing the suction cup 4 to move upwards via the connecting rod 14, achieving separation of the upper cover 16 from the lower cover 16. Finally, the first electric telescopic rod 521 drives the clamping plate 522 to reset, while simultaneously rotating the lead screw 6 to restore the clamping cylinder 51 to its original position. The lid 16 is then transferred to the designated position via the drive device, and the negative pressure device is shut off, completing the operation. This process significantly reduces the intensity of manual operation while ensuring good lid separation effect and high stability.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
