[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figures 1 to 4A paper bag machine flat handle device comprises: a mounting plate 1; a front conveying mechanism 2, which is mounted on the mounting plate 1, and the front conveying mechanism 2 can convey the handle; an upper conveying mechanism 3 and a lower conveying mechanism 4, which are mounted on the mounting plate 1, and the upper conveying mechanism 3 and the lower conveying mechanism 4 are arranged opposite to each other, and the handle can be conveyed between the upper conveying mechanism 3 and the lower conveying mechanism 4; the upper conveying mechanism 3 and the lower conveying mechanism 4 are arranged on the discharge end of the front conveying mechanism 2; the positioning chain of the front conveying mechanism 2 drives the positioning paddle to position the handle and send it to the tracking acceleration belt, and the upper and lower tracking belts clamp the handle and convey it forward and accelerate it to the same speed as the paper feeding platform, and then the handle is attached to the paper.

[0044] The waste discharge mechanism 5 is installed between the front conveying mechanism 2 and the lower conveying mechanism 4. The waste discharge mechanism 5 can connect or block the connection between the handle and the front conveying mechanism 2 and the lower conveying mechanism 4. When the paper feeding platform is out of paper or the handle is incomplete, the waste discharge mechanism 5 will realize the waste discharge function without the need to shut down the whole machine.

[0045] The upper conveying mechanism 3 has an upper conveying belt 32, which is rotatably mounted on the mounting plate 1. The lower conveying mechanism 4 includes a lower conveying belt 41, which is rotatably mounted on the mounting plate 1, and the handle can be transported between the upper conveying belt 32 and the lower conveying belt 41. The positioning chain of the front conveying mechanism 2 drives the positioning paddle to position the handle and send it to the tracking acceleration belt. The upper and lower tracking belts clamp the handle and transport it forward and accelerate it to the same speed as the paper feeding platform, so that the handle is attached to the paper.

[0046] The waste discharge mechanism 5 comprises: a waste discharge driving shaft 54, rotatably mounted on the mounting plate 1; a waste discharge driving wheel 55, fixedly mounted on the waste discharge driving shaft 54; a waste discharge swing arm 51, a first end of which is rotatably mounted on the waste discharge driving shaft 54; a waste discharge driven shaft 52, mounted on the second end of the waste discharge swing arm 51; a waste discharge driven wheel 53, mounted on the waste discharge driven shaft 52; a waste discharge belt, wound around the waste discharge driving wheel 55 and the waste discharge driven wheel 53; and a driving mechanism capable of driving the waste discharge swing arm 51 to swing. During normal operation, the waste discharge opening and closing belt (waste discharge belt) is in a closed state, and the handle passes smoothly and sticks to the paper. When waste discharge is required, the cylinder opens the waste discharge opening and closing belt, and the handle falls onto the waste conveyor belt and is transported outside the equipment. When the paper feeding platform is out of paper or the handle is incomplete, the waste discharge mechanism 5 will realize the waste discharge function without the need for overall shutdown.

[0047] The waste discharge driving wheel 55 is close to the discharge end of the front conveying mechanism 2, and the waste discharge driven wheel 53 is close to the feed end of the lower conveying belt 41. A complete hand-carrying passage path can be formed, and the hand-carrying can be transported more stably and reliably.

[0048] The waste discharge belt is arranged between the front conveying mechanism 2 and the lower conveying belt 41; the waste discharge belt and the lower conveying belt 41 are located below the upper conveying belt 32 and can cooperate with the upper conveying belt 32 to convey the handle. During normal operation, the waste discharge opening and closing belt (waste discharge belt) is in a closed state, and the handle passes smoothly and sticks to the paper. When waste discharge is required, the cylinder opens the waste discharge opening and closing belt, and the handle falls into the waste conveying belt and is transported outside the equipment. When the paper feeding platform is out of paper or the handle is incomplete, the waste discharge mechanism 5 will realize the waste discharge function without the need to shut down the entire machine.

[0049] The driving mechanism is a waste discharge driving cylinder 56, the base of which is hinged on the mounting plate 1, and the piston rod of which is hinged to the waste discharge swing arm 51. When waste discharge is required, the waste discharge driving cylinder 56 opens the waste discharge opening and closing belt, and the handle falls onto the waste conveyor belt to be transported outside the equipment. When the paper feeding platform is out of paper or the handle is incomplete, the waste discharge mechanism 5 will realize the waste discharge function without the need for overall shutdown.

[0050] The conveying speed of the upper and lower conveying belts 41 is greater than the conveying speed of the front conveying mechanism 2. The positioning chain drives the positioning paddle to position the handle and send it to the tracking acceleration belt. The upper and lower tracking belts clamp the handle and convey it forward and accelerate it to the same speed as the paper feeding platform, so that the handle is attached to the paper.

[0051] An adjustment mechanism 31 is provided on the first end of the upper conveyor belt 32, and the first end of the upper conveyor belt 32 can be adjusted in height under the drive of the adjustment mechanism 31. The adjustment mechanism 31 comprises: an adjustment bracket 311, mounted on the mounting plate 1; a slider 313, slidably mounted in the mounting groove of the adjustment bracket 311; an upper rotating shaft 312 of the upper belt is rotatably mounted on the slider 313; a guide rod 314, a first end of which is fixedly mounted on the slider 313, and a second end of the guide rod 314 is slidably mounted on the adjustment bracket 311; and a spring 315 is sleeved on the guide rod 314. When a paper jam (handle jam) occurs in the device, the first end of the upper conveyor belt 32 can be lifted to facilitate the removal of the jammed paper. At the same time, it is also convenient for the installation, adjustment, maintenance and care of the upper conveyor belt 32.

[0052] After adopting the above structure, when the paper feeding platform is out of paper or the handle is incomplete, the waste discharge function can be realized without stopping the machine.
