However, since the metal can lids are cylindrical after sealing, there is an instability problem during belt transportation. There is an urgent need for a circulating discharge device to improve the stability of metal can lid transportation. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a circulating discharge device for a film wrapping machine.

[0005] This utility model provides a circulating discharge device for a film wrapping machine, including a frame, with fixed plates on both sides of the frame, and chains rotatably arranged on both sides between the two fixed plates. Several spaced support shafts are arranged between the two chains, and the support shafts between adjacent support shafts are used for supporting and transporting workpieces.

[0006] Furthermore, the two fixing plates are provided with anti-deviation devices for workpiece positioning.

[0007] Furthermore, the anti-deviation device includes a mounting bracket mounted on a fixed plate and a limit rail that can be detachably mounted on the mounting bracket.

[0018] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown 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 this utility model, and should not be construed as limiting the utility model.

[0019] like Figure 1 As shown, this embodiment discloses a circulating discharge device for a film wrapping machine, including a frame 17. Fixed plates 1 are provided on both sides of the frame 17, and the fixed plates 1 are bolted to the frame 17. Chains 2 are rotatably arranged on both sides between the two fixed plates 1. The chains 2 are driven to rotate by a drive device. The drive device includes a drive component mounted on the frame 17, a drive shaft 8 connected to the drive component, and a sprocket 9 mounted on the drive shaft 8. The sprocket 9 is connected to the chain 2. The drive component is an electric motor, which drives the drive shaft 8 to rotate, which in turn drives the chain 2 to rotate via the sprocket 9. Several spaced support shafts 3 are arranged between the two chains 2, and adjacent support shafts 3 are used for supporting and transporting workpieces. A metal can lid 18 is supported and fixed between the two support shafts 3. Anti-deviation devices for workpiece positioning are provided on the two fixed plates 1. The anti-deviation devices are used to fix and limit the front and rear of the metal can lid 18, preventing the metal can lid 18 from shifting to either side.

[0020] like Figure 2 As shown, in this embodiment, the anti-deviation device consists of a mounting bracket 4 mounted on a fixed plate 1 and limiting rails 5 detachably mounted on the mounting bracket 4. The limiting rails 5 on both sides limit the movement of the metal can lid 18, with two mounting brackets 4 on each side. The limiting rails 5 are equipped with connecting rods 6, while the mounting brackets 4 have connecting holes for inserting the connecting rods 6 and are fitted with rotatable threaded locking parts 7. The limiting rails 5 engage with the connecting holes of the mounting brackets 4 via the connecting rods 6 and are locked in place by the threaded locking parts 7, thus achieving a stable connection between the limiting rails 5 and the mounting brackets 4. When it is necessary to adjust the distance between the two limiting rails 5, simply loosen the threaded locking parts 7 and then adjust the position of the connecting rods 6 to meet the limiting requirements of metal can lids 18 of different widths.

[0021] like Figure 1 , Figure 3As shown, a sealing device is also provided on the frame 17 above the fixed plate 1. The sealing device is used for packaging metal can lids 18. Specifically, in this embodiment, the sealing device includes a slide plate 10 slidably disposed on the frame 17 and a heat-sealing plate 11 connected to the slide plate 10. The heat-sealing plate 11 and the slide plate 10 are movably connected by a guide rod 12. A spring 13 is sleeved on the guide rod 12. One end of the spring 13 is connected to the heat-sealing plate 11, and the other end is connected to the slide plate 10. When the gripper places the metal can lid 18 to be sealed on the support shaft 3, the sealing plates on both sides move towards each other under the drive of the cylinder, clamping the sealing film and performing heat sealing. Under the combined action of the guide rod 12 and the spring 13, the two sealing plates achieve elastic buffer contact. The heat-sealing plate 11 has an upper heat-sealing strip 14 and a lower heat-sealing strip 15 on the side closest to the workpiece, with a cutting wire 16 (for heating) between them. The upper heat-sealing strip 14, the lower heat-sealing strip 15, and the cutting wire 16 are all heat-sealed by electric heating. The specific principle is well known to those skilled in the art and will not be described in detail in this embodiment. The upper heat-sealing strip 14 and the lower heat-sealing strip 15 are heat-sealed, and then cut by the cutting wire 16 in the middle, thereby completing the sealing of the metal can lid 18.

[0022] Working principle: The grippers on frame 17 move the metal can lid 18 to be packaged above the sealing film and press down on the sealing film (e.g., Figure 4 As shown, the sealing film is rotated across the sealing device via two sealing film rolls mounted on the frame 17. Next, the metal cap is placed on the two support shafts 3 of the circulating conveyor. The sealing device is then started, and the metal can cap 18 is packaged using the heat-sealing plate 11 and cut into sections using the cutting wire 16. Subsequently, the motor is started, driving the transmission shaft 8 to rotate, which in turn drives the chain 2 via the sprocket 9, thus moving the support shaft 3 and delivering the packaged metal can cap 18 to the designated position. With the continuous rotation of the chain 2, the support shaft 3 achieves a circulating conveying function, ensuring a more stable and efficient transportation process for the metal can cap 18.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
