The belt feeding device of the automatic packing machine is matched with the automatic packing machine in the prior art for use. In this embodiment, the side plate 102 and the base 101 may be connected by welding or fixing by screws, a sliding groove 105 is disposed at the side plate 102, and the sliding block 109 is slidably connected with the sliding groove 105. The sliding block 109 is in clearance fit with the sliding groove 105, so as to reduce the friction between the sliding block 109 and the sliding groove 105 during use. The slider 109 may be made of metal or plastic, and when the slider 109 and the first pulley 103 are selected, the mass of the slider 109 and the first pulley 103 should be considered sufficiently to prevent the packing belt from being broken due to the excessive mass thereof. After the side plate 102 is connected to the base 101, the side plate 102 is preferably kept in a vertical state to fully utilize the gravity of the slider 109 and the first pulley 103.

The top of the side plate 102 is provided with a pulley block for changing the running direction of the PE tape, the pulley block comprises a second pulley 106 and a third pulley 104, wherein the second pulley 106 and the third pulley 104 are preferably arranged at two sides of the chute 105, and the axes of the first pulley 103, the second pulley 106 and the third pulley 104 are kept parallel when the tape feeding device of the automatic packaging machine is assembled. Specifically, the PE belt is drawn out from the spool, turns through the second pulley 106, winds around the first pulley 103, turns through the third pulley 104, and passes through the wire feeding arm after turning through the third pulley 104 to be connected with a rope knot of the automatic packing machine.

And a dynamic measurement plate 107 is connected with the slide block 109, the dynamic measurement plate 107 slides up and down along with the slide block 109, when the slide block 109 moves to a specified position, the detector is triggered, and the control unit receives a trigger signal of the detector to control the start and stop of the driving motor 113. The length of the dynamic measurement plate 107 is controlled to be 350mm, and the distance between the detector 108 and the base 101 is slightly smaller than the length of the dynamic measurement plate 107.

The feeding mechanism comprises a bracket 114, a first roller 111, a second roller 112 and a driving motor 113, wherein the first roller 111 and the second roller 112 are respectively connected with the bracket 114 in a rotating manner, the driving motor 113 is connected with the bracket 114, and the driving motor 113 is connected with a rotating wheel at the position of the first roller 111 or the second roller 112 through a transmission belt.

The belt winding arm 115 is connected with an automatic packing machine and used for winding the PE belt on an object to be bundled, a flattening nose 201 is arranged at the position, close to the end portion, of the belt winding arm 115, the flattening nose 201 is used for preventing the PE belt from being coiled when the PE belt is sent into the rope knotting device by the belt winding arm 115, and the length of the flattening nose 201 is preferably 23mm, and the height of the flattening nose is preferably 2 mm.

When the tape feeding device of the automatic packing machine is used, the PE tape shaft is firstly placed between the first roller 111 and the second roller 112, the PE tape is drawn out, respectively wound around the second pulley 106, the first pulley 103 and the third pulley 104, passes through the flattening nose 201 of the winding arm 115, and finally the end of the PE tape is connected with the knotter of the automatic packing machine. It can be understood that when the automatic packing machine performs the packing action, the PE tape is wound on the packed object, the tensile force of the PE tape increases to drive the sliding block 109 to ascend, and when the sliding block 109 ascends to the upper side of the detector, that is, when the movable detecting plate 107 leaves the detector, the detector triggers. The control unit controls the driving motor 113 to rotate after receiving the trigger signal of the detector. The driving motor 113 drives the first roller 111 or the second roller 112 to rotate and drives the PE tape spool to roll and send out the thread. The slider 109 slowly falls down as the PE tape is fed out. When the slide 109 brings the moving plate 107 down to the position of the detector 108, the detector detects the moving plate. The control unit controls the driving motor 113 to stop rotating after receiving the signal of the detector. It will be appreciated that the shoe 109 will continue to descend a distance due to the rotational inertia of the drive motor 113 and the first and

second rollers

111, 112 and the PE tape spool itself. In the above-described entire process, the PE tape is always kept in a taut state by the weight of the slider 109 and the first pulley 103 itself, and therefore, the PE tape can be prevented from being wound up in the baling process. When the wire is fed, the driving motor 113 provides the driving force for feeding the wire, so that the wire breakage caused by overlarge tension of the PE belt is avoided.

It will be appreciated that the control functions of the control unit are implemented in dependence on the control unit hardware itself and a program installed in the control unit. The chip of the control unit can be a single chip microcomputer or a PLC programmable controller.

These two devices constitute the prior art and their specific principles and structures are not described herein in excessive detail.

In this embodiment, the driving motor 113 is a servo motor or a stepping motor, and the servo motor or the stepping motor can precisely adjust the number of revolutions. When the PE winding machine is used, the stopping action can be rapidly executed, so that the phenomenon that the PE winding machine is coiled due to the fact that the PE is loose because the slide block 109 contacts the base 101 because of excessive wire feeding caused by the existence of the rotational inertia of the common motor is prevented.

In this embodiment, the surfaces of the first roller 111 and the second roller 112 are provided with anti-slip layers, and the anti-slip layers increase the friction force between the first roller 111 and the second roller 112 and the PE belt shaft, thereby preventing the first roller 111 and the second roller 112 from slipping with the PE belt shaft during the thread feeding process. Wherein, the material of skid resistant course is silica gel or rubber.
