Description

Technical Field

[0001] This utility model relates to a packing machine, and more particularly to a strapping and positioning mechanism in a packing machine. Background Technology

[0002] The strapping machine includes a core mechanism, which includes a heat-bonding mechanism, a strapping top mechanism, and a strapping cutter mechanism. The movement of these mechanisms is controlled by a series of cams mounted on the core shaft, driven by a core motor, to secure, cut, and bond the strapping. One type of strapping machine uses a strap-reaming mechanism to arrange the strapping around the bottom of the item, thus wrapping the strapping around it.

[0003] These types of strapping machines require pressing one end of the strapping tape upwards at certain stages of the working process, and also require lateral movement perpendicular to the strapping tape at certain stages. This work is accomplished by a tape pressing mechanism, which is currently connected to the sliding plate of the machine core. The lateral movement is achieved by pressing the strapping tape upwards through the upward rotation of the tape pressing component. This requires cantilever and multiple connecting links, making the structure relatively complex, prone to failure, and the upward force unstable. Utility Model Content

[0004] The purpose of this utility model is to provide a pressing and positioning mechanism that can improve the lifting effect. To this end, this utility model adopts the following technical solution:

[0005] A belt pressing and positioning mechanism includes a driving part and a swingable belt pressing assembly. The belt pressing assembly includes a swing arm and a belt pressing member movably connected to the swing arm, allowing the belt pressing member to move away from and towards the swing axis. The belt pressing and positioning mechanism includes a first control part and a second control part, a first reset part and a second reset part. The swing arm swings under the control of the first control part, driven by the driving part and the first reset part. The belt pressing and positioning mechanism is provided with an upper lifting mechanism, which rises and falls under the control of the second control part, driven by the driving part and the second reset part. The belt pressing member cooperates with the upper lifting mechanism, and the upper lifting mechanism pushes the belt pressing member upwards when rising.

[0006] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions:

[0007] The pressure and positioning mechanism is a pressure and positioning mechanism in the core of the packing machine. The swing arm is separated from the sliding plate swing arm in the core and swings independently relative to the sliding plate swing arm. The driving part includes a drive motor, which is a core motor. The swing axis is parallel to the core shaft axis.

[0008] The movement shaft includes a first movement shaft and a second movement shaft that are parallel to each other. The first movement shaft and the second movement shaft are connected by a transmission mechanism and rotate synchronously. The first movement shaft or the second movement shaft is connected to the movement motor. The first control part adopts a first control cam, and the second control part adopts a second control cam. The first control cam and the second control cam are arranged side by side along a direction perpendicular to the movement shaft and are respectively fixed on the first movement shaft and the second movement shaft.

[0009] The upper lifting mechanism includes a first guide groove and an upper lifting member. The upper lifting member includes a guide portion and is slidably connected to the first guide groove, and can move up and down under the guidance of the first guide groove. The lower end of the upper lifting member is engaged with the second control cam through a cam engagement component. The pressure belt component includes a horizontal portion and a vertical portion. The vertical portion is movably connected to the swing arm. The horizontal portion extends above the upper lifting member and can be lifted by the upper lifting member.

[0010] The swing arm is provided with a second guide groove, and the vertical part is slidably connected to the guide groove, so that it can move up and down under the guidance of the second guide groove.

[0011] A reset mechanism is provided between the pressure band component and the swing arm, so that the pressure band component can cooperate closely with the upper lifting mechanism.

[0012] The rocker arm may be equipped with a cam engagement component that engages with the first control cam.

[0013] The second reset part is located between the movement frame and the upper top part.

[0014] The compression positioning mechanism is the compression positioning mechanism in the core of the packing machine, and the first reset part is located between the core frame and the swing arm.

[0015] One end of the first movement shaft is connected to the second movement shaft via a transmission mechanism, and the other end of the first movement shaft is connected to the movement motor.

[0016] By adopting the technical solution of this utility model, after the pressing and positioning mechanism of this utility model is separated from the slide plate, it directly acts on the pressing component on the slide bar through the swing rod and through a separate lifting mechanism. While ensuring the lateral forward and backward movement function of the pressing and positioning mechanism, it improves the lifting effect and helps to increase the service life.
