[0041] The present invention provides the following embodiments

[0042] Example 1

[0043] The embodiment of the present invention provides a rotary cutting type automatic feeding bag device, such as Figure 1 As shown, it includes a material conveying mechanism and a rotary cutting mechanism, and the material conveying mechanism and the rotary cutting mechanism are correspondingly connected. The rotary cutting mechanism is used to cut off the material bag 10 conveyed by the material conveying mechanism, and the rotation tangent direction of the rotary cutting mechanism is the same as the conveying direction of the material conveying mechanism.

[0044] The working principle and beneficial effects of the above technical solution are:

[0045] The rotary cutting mechanism adopts a method of rotary cutting of material bags. The rotary tangent is in the same direction as the material conveying, which is convenient for delivering the cut material bags 10 to the subsequent pillow packaging machine or other target equipment. Compared with the reciprocating cutting method on the market, the rotary cutting of material bags has no empty return stroke, which saves cycle time and solves the technical problem that with the development of pillow packaging machines, the stable production speed of high-speed pillow packaging machines has reached 275 bags / minute, and the corresponding supporting feeding bagging machines cannot match their speed.

[0046] Example 2

[0047] On the basis of Example 1, Figure 1-4 As shown, the rotary cutting mechanism includes a working shell 3, which is fixedly arranged at the front end of the mounting plate 1, and a working cavity 31 is penetrated at the front and rear ends of the working shell 3, and buffer grooves 32 are symmetrically arranged on the left and right sides of the working cavity 31, and the buffer groove 32 on the right side is connected to the motor cavity in the mounting plate 1;

[0048] A motor 1 34 is slidably provided in the motor cavity, and the motor 1 34 is fixedly connected to a motor shaft 1 35. The motor shaft 1 35 passes through the buffer groove 32 on the right, the motor cavity and the working cavity 31 and enters the buffer groove 32 on the left. A buffer cylinder 1 312 is fixedly provided in the buffer groove 32 on the left, and the buffer cylinder 1 312 is rotatably connected to the motor shaft 1 35. A buffer cylinder 2 33 is fixedly provided in the motor cavity, and the buffer cylinder 2 33 is fixedly connected to the motor 1 34.

[0049] The rotary cutting mechanism also includes a mounting sleeve 36, which is fixedly mounted on the motor shaft 35 in the working chamber 31, and a plurality of T-slots 37 are evenly distributed around the arc end of the mounting sleeve 36, and the T-slots 37 run through the left and right ends of the mounting sleeve 36, and the T-slots 37 are connected to the T-shaped connection seat of the cutting knife 310;

[0050] The T-slot 37 is connected to the cutting knife 310 through a detachable mechanism, which includes a plurality of threaded grooves 38 symmetrically connected to the left and right sides of the T-slot 37, and the plurality of threaded grooves 38 are evenly spaced along the left and right length directions of the T-slot 37. The T-slot 37 cooperates with the T-shaped connecting seat 311 of the cutting knife 310, and the T-shaped connecting seat 311 of the cutting knife 310 is provided with threaded holes, which are connected to the threaded grooves 38 one by one, and the threaded holes and the threaded grooves 38 are threadedly connected to the bolts 39.

[0051] The working principle and beneficial effects of the above technical solution are:

[0052] When the rotary cutting mechanism is working, the motor 34 is started to drive the motor shaft 35 to rotate, and the motor shaft 35 drives the installation sleeve 36 to rotate, and the installation sleeve 36 drives the cutting knife 310 connected thereto to rotate, so as to cut the material bag 10 passing through the installation sleeve 36. The cooperation between the T-slot 37 and the T-connecting seat 311 can improve the connection stability between the cutting knife 310 and the installation sleeve 36. The threaded connection of the threaded hole, the threaded groove 38 and the bolt 39 is used to install and disassemble the cutting knife 310. By setting the buffer cylinder 1 312 and the buffer cylinder 2 33, the motor 1 34 and the motor shaft 1 35 can be moved up and down, and the buffer cylinder 1 312 and the buffer cylinder 2 33 have a shock-absorbing and buffering effect on the up and down movement of the motor 1 34 and the motor shaft 1 35, so that the cutting knife 310 on the installation sleeve 36 can move up and down when cutting the material bag 10. When the cutting knife 310 is subjected to excessive cutting force, there is a certain elastic avoidance, which greatly extends the service life of the cutting knife 310.

[0053] Example 3

[0054] On the basis of Example 2, Figure 1-3As shown, the material conveying mechanism includes a pulling mechanism, a guiding mechanism, an ultrasonic mechanism and a material buffering mechanism. The pulling mechanism includes a U-shaped plate 2. The rear end of the U-shaped plate 2 is fixedly connected to the front end of the mounting plate 1, and the U-shaped plate 2 is arranged at the front side of the working shell 3.

[0055] The guiding mechanism includes a fixed plate 1 41, a fixed plate 2 91 and a fixed plate 3 63. The fixed plate 1 41 and the fixed plate 2 91 are fixedly connected to the front end of the mounting plate 1, and the fixed plate 1 41 is arranged on the front side of the U-shaped plate 2. The left and right sides of the fixed plate 1 41 are rotatably provided with guide wheels 4. The fixed plate 2 91 is arranged on the front side of the fixed plate 1 41. The front and rear sides of the fixed plate 2 91 are fixedly connected to the fixed plate 4 9 through fixed rods 93. The ends of the fixed plate 2 91 and the fixed plate 4 9 that are close to each other are evenly provided with a number of rotating wheels 92 along the front and rear directions. The fixed plate 3 63 is fixedly connected to the front end of the mounting plate 1, and the fixed plate 3 63 is rotatably connected to the material guide barrel 62. The buffer material mechanism includes a buffer shell 6, which is arranged at the front lower end of the material guide barrel 62. The upper end of the buffer shell 6 is provided with a buffer material cavity, and a buffer material barrel 61 is rotatably provided in the buffer material cavity.

[0056] The working principle and beneficial effects of the above technical solution are:

[0057] The pulling mechanism in the material conveying mechanism is used to pull the material bag 10. When the material conveying mechanism is working, the material bag 10 passes through the buffer material cylinder 61, the guide cylinder 62, the rotating wheel 92, and the guide wheel 4 in the buffer material cavity in turn, and then enters the rotary cutting mechanism for cutting under the pulling of the pulling mechanism. When the pulling mechanism is working, the motor 21 drives the motor shaft 22 to rotate, and drives the pulling wheels 23 on the left and right sides to rotate. The pulling wheels 23 contact the edge of the material bag 10 and are used to pull the edge of the material bag 10. The buffer material cylinder 61 and the guide cylinder 62 rotate during the conveying process of the material bag 10, which guides the conveying of the material bag 10, so that the material The transmission of the material package 10 remains smooth, the rotating wheels 92 are distributed on the lower side of the material package 10, and play a guiding and supporting role in the transmission of the material package 10. The guide wheels 4 are distributed on the left and right sides of the material package 10, and play a limiting role in the transmission of the material package 10 to prevent the material package 10 from shifting in the left and right directions. The mounting plate 1 can be tilted so that the material conveying mechanism and the rotary cutting mechanism are tilted at a certain angle to facilitate the transmission of the material package 10, and the material package 10 is convenient to fall on the high-speed pillow packaging machine after being cut by the rotary cutting mechanism. The cut material package 10 just falls on the material on the high-speed pillow packaging machine, ensuring that the material transmitted on the high-speed pillow packaging machine corresponds to the cut material package 10 one by one.

[0058] Example 4

[0059] On the basis of Example 3, Figure 1 As shown, the ultrasonic mechanism includes two detection heads 5 and two detection rods 51, and the two detection heads 5 and the two detection rods 51 are symmetrically arranged on the upper and lower sides of the mounting plate 1, and the gaps between the detection heads 5 and the fixing plates 2 91 and 4 9 are arranged correspondingly, and the two detection rods 51 are arranged between the fixing plates 1 41 and 2 91, and the upper detection rod 51 is slidably connected to the mounting plate 1 along the up and down directions, and the lower detection rod 51 is fixedly connected to the mounting plate 1.

[0060] The working principle and beneficial effects of the above technical solution are:

[0061] By setting up an ultrasonic detection mechanism, the gaps between the detection head 51 and the fixing plates 2 91 and 4 9 are set correspondingly to avoid the rotating wheel 92 affecting the operation of the detection head 51. The detection head 51 detects once at a certain interval to detect the length of the material package 10 passing through the detection head 51, to determine whether the conveying speed of the material package 10 remains consistent, to avoid the length of the cut material package 10 being unqualified due to the material package 10 being conveyed too fast or too slow. When the material package 10 passes through the detection rod 51, the upper detection rod 51 is pushed to move upward to detect the thickness of the material package 10 to detect whether the thickness of the material package 10 is qualified. If the detection is abnormal, the ultrasonic mechanism controls the material conveying mechanism and the rotary cutting machine to stop working, thereby avoiding waste of resources.

[0084] When the cutting knife 310 cuts the material bag 10, the motor 3 804 is turned on, and the motor 3 804 drives the power sleeve 806 to rotate through the motor shaft 805, and the power sleeve 806 drives the fan blade 818 to rotate. The fan blade 818 drives the connecting block 2 814 to rotate through the rotating rod 817. The angle of the fan blade 818 can change under the centrifugal effect as the speed of the power sleeve 806 rotates. The cooperation of the rotating rod 817, the sliding groove 2 819 and the sliding shaft 2 820 guides the rotation of the fan blade 818, improves the stability of the fan blade 818, and thus changes the blowing volume of the fan blade 818. The air enters from the air inlet 803 and is blown out through the dust filter 802. The filter in the air inlet 803 and the dust filter 802 both filter the dust in the air. To prevent dust from getting inside the cooling chamber 801 and on the cutting knife 310, which would pollute the cut material bag 10, the blown air cools the cutting knife 310, which is beneficial to increasing the service life of the cutting knife 310. After the cutting knife 310 has finished cutting the material bag 10, the motor 3 804 is stopped, and the electric telescopic rod 833 is started.

The sliding groove 1 838 guides the movement of the sliding shaft 1. The movement of the sliding shaft 1 first drives the fan blade 818 to move until the sliding groove 2 819 is free of The fan blade 818 drives the connecting block 814 to move back and forth through the rotating rod 817. The cooperation between the connecting block 813 and the through hole 807, and the cooperation between the mounting block 809 and the buffer cavity 808 guide the movement of the connecting block 814. The reciprocating movement of the connecting block 814 drives the limit plate 815 to move back and forth. The movement of the limit plate 815 drives the matching block 816 to move back and forth. The matching block 816 drives the matching block 837 to move back and forth. When the matching block 837 moves downward, the blocking block 834 is driven downward by the connecting block 836 to block the liquid outlet of the liquid supply channel 828.

When the blocking block 834 moves upward, the liquid outlet of the liquid supply channel 828 is no longer blocked. When the blocking block 834 moves downward, the push rod 831 moves inward, and the push rod 831 drives the push block 830 to move inward. The push block 830 pushes the liquid outlet of the liquid supply channel 828 into the nozzle, so that the nozzle sprays the cleaning liquid to clean the cutting knife 310, saving manpower. By setting a motor 4 811, the motor 4 811 is started to drive the threaded rod 812 to rotate, and the threaded rod 812 rotates to drive the connecting block 1 813 to move, and the connecting block 1 813 drives the connecting block 2 814 to move.It is used to change the initial length of the connecting block 814 and the power sleeve 806, thereby changing the initial position of the matching block 816 and the matching block 837, so that the position of the blocking block 834 at the outlet of the liquid supply channel 828 changes, and the flow area of ​​the outlet of the liquid supply channel 828 can be changed, so as to achieve the purpose of adjusting the amount of liquid sprayed by the nozzle.
