[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0022] like Figure 1-Figure 8 A glue dispensing device for bag production shown in the figure comprises a workbench 1, and a top frame 2 fixedly connected to the top of the workbench 1, a glue dispensing mechanism 3 is arranged inside the top frame 2, and the glue dispensing mechanism 3 is mainly composed of a multi-axis moving mechanism and a glue pushing component and other structures, which is a mature technology in the prior art and will not be described in detail here. A material passing trough 4 is provided through the side wall of the top frame 2, a pair of fixed plates 5 are arranged on the top of the workbench 1 and located at the material passing trough 4, and the fixed plates 5 are fixedly connected to the limiting plates 6 on the sides close to each other, a material frame 7 is fixedly connected to the side wall of the top frame 2 and located above the fixed plates 5, and a top plate 8 is fixedly connected to the top of the fixed plates 5 and located in the material frame 7, an intermittent material pushing mechanism is arranged between the fixed plates 5, and a conveying line 9 connected to the limiting plate 6 is arranged on the top of the workbench 1; The intermittent pushing mechanism includes a driving motor 10. A pair of mounting plates 11 are fixedly connected on the top of the workbench 1 and located between the fixed plates 5. A screw rod 12 is rotatably connected between the mounting plates 11. The driving motor 10 is fixedly connected to one of the side walls of the mounting plates 11. The output end of the driving motor 10 passes through the mounting plate 11 and is fixedly connected to the side wall of the screw rod 12. A sliding block 13 is threadedly connected to the outer wall of the screw rod 12. It should be noted that, as can be seen from the accompanying drawings, a guide rod passing through the sliding block 13 is provided between the mounting plates 11. Therefore, it will not rotate with the screw rod 12, but will only move horizontally. The guide rod is a mature technology in the prior art and will not be described in detail here. A pair of adjusting plates 14 are fixedly connected on the top of the workbench 1 and located between the fixed plates 5. A sliding plate 15 is slidably connected between the adjusting plates 14. A connecting frame 16 is fixedly connected between the sliding block 13 and the sliding plate 15. Three push plates 17 are slidably connected through the top of the sliding plate 15, and the bottom ends of the side walls of the push plates 17 are slidably connected with positioning pins 18. A pair of upper transverse grooves 19 are opened on the side wall of one of the adjustment plates 14, and a lower transverse groove 20 is opened on the side wall of the other adjustment plate 14 and located between the upper transverse grooves 19. By staggered upper transverse grooves 19 and lower transverse grooves 20 on the two adjustment plates 14, adjacent positioning pins 18 can be prevented from sliding into adjacent transverse grooves. The bottoms of both ends of the lower transverse grooves 20 and the upper transverse grooves 19 are both provided with oblique grooves 42 inclined toward the middle, and the side walls of the adjustment plate 14 are provided with connecting grooves 44 between the oblique grooves 42. The lower transverse grooves 20 and the upper transverse grooves 19 are provided with recessed upper card grooves 21 on the side close to the conveyor line 9, and the lower transverse grooves 20 and the upper transverse grooves 19 are provided with recessed lower card grooves 22 on the side away from the conveyor line 9. An upper spring 23 is fixedly connected between the side wall of the push plate 17 and the outer wall of the positioning pin 18; The connection between the upper card slot 21 and the inclined slot 42 is inclined, which is convenient for the positioning pin 18 to slide into the inclined slot 42. The connection between the lower card slot 22 and the lower transverse slot 20 and the upper transverse slot 19 is inclined, so that the positioning pin 18 can slide into the upper transverse slot 19 and the lower transverse slot 20 after resetting. The end of the positioning pin 18 located in the middle is movably connected to the inner side of the lower transverse slot 20, and the end of the positioning pin 18 located on both sides is movably connected to the inner side of the upper transverse slot 19. The end of the positioning pin 18 is set to a smooth arc surface to improve the silkiness when squeezing the positioning pin 18. The distance between the top of the limiting plate 6 and the top of the fixing plate 5 is the same as the thickness of the luggage nameplate, so as to ensure that when the bottom nameplate is pushed away, the top nameplate will not be pushed away by the push plate 17 at the same time under the limit of the top frame 2, and the initial position of the push plate 17 is set higher than the top of the limiting plate 6. When the nameplates of bags and luggage are glued, the nameplates to be glued are stacked and placed between the top plates 8 in the material frame 7, and then the lowest nameplate falls between the fixed plates 5, and the limit plate 6 is used to press against the nameplate. At this time, the push plate 17 at the rear end is located at the side wall of the nameplate, and then the drive motor 10 can be controlled to start and drive the screw rod 12 to rotate, thereby driving the threaded sliding block 13 to move, and at the same time, the sliding plate 15 is driven to slide between the adjustment plates 14 through the connecting frame 16, and the push plate 17 is driven to move to the side close to the conveyor line 9, and the nameplate falling on the limit plate 6 is pushed away. At the same time, the positioning pin 18 is driven to slide in the upper transverse groove 19 and the lower transverse groove 20; When the positioning pin 18 moves into the upper slot 21, the driving motor 10 can be controlled to rotate in the opposite direction to drive the sliding block 13 to reset. At this time, since there is a step between the upper slot 21 and the upper transverse slot 19 and the lower transverse slot 20, the elastic force of the upper spring 23 will push the end of the positioning pin 18 to insert into the upper slot 21, and the connection between the upper slot 21 and the inclined slot 42 is an inclined surface, so that under the pulling force of the sliding block 13 moving backward, the positioning pin 18 will be driven to slide into the inclined slot 42, and then the push plate 17 will be driven to slide downward and slide out of the top of the limit plate 6. Then the positioning pin 18 slides into the connecting slot 44, and at the same time, the positioning pin 18 is squeezed outward to stretch the upper spring 23. At the same time, when the nameplate at the bottom of the material frame 7 is pushed away, the gravity of the stacked nameplates pushes the bottom nameplate to fall on the limit plate 6; However, when the push plate 17 is reset, it will slide under the nameplate under the action of the positioning pin 18, and then after passing the nameplate, the positioning pin 18 will slide from the connecting groove 44 into the inclined groove 42 at the other end, and then slide into the lower card slot 22, so that under the elastic force of the upper spring 23, the positioning pin 18 is pushed to insert into the lower card slot 22, and finally the drive motor 10 can be controlled to rotate forward. Since the connection between the lower card slot 22 and the upper transverse groove 19 and the lower transverse groove 20 is an inclined surface, it will slide into the upper transverse groove 19 and the lower transverse groove 20 under the push of the sliding block 13. This process is repeated, and the luggage nameplate can be pushed to the bottom of the dispensing mechanism 3 for dispensing processing, and the nameplate after the dispensing is completed will be pushed to the conveyor line 9 for subsequent production under the thrust of the push plate 17.

[0023] In order to improve the smoothness of the push plate 17 when it is reset, the side walls of the push plate 17 are fixedly connected with a movable plate 24, and a lower spring 25 is fixedly connected between the bottom of the movable plate 24 and the top of the sliding plate 15. When the positioning pin 18 slides into the connecting groove 44 and is squeezed, it will drive the push plate 17 and the movable plate 24 to slide downward, thereby compressing the lower spring 25. Subsequently, when the positioning pin 18 slides out of the other inclined groove 42, the push plate 17 will be pushed to slide upward under the elastic force of the lower spring 25, making the device run more smoothly and avoiding jamming.

[0024] In order to remind the staff to add a nameplate when the material in the material box 7 is running out, an infrared sensor 26 is fixedly connected to the bottom of the side wall of the material box 7, and an inward groove is opened on the side wall of the top frame 2 at a position corresponding to the infrared sensor 26, and a reflective plate 27 is fixedly connected to the inside of the groove. An alarm 28 is fixedly connected to the top of the top frame 2, and the infrared sensor 26 is electrically connected to the alarm 28 through a controller; During the process of loading the nameplates into the material frame 7, the nameplates will block the red light emitted by the infrared sensor 26, and the red light cannot be reflected back. Later, when the nameplates in the material frame 7 are gradually loaded, the red light will be unblocked and shine on the reflective plate 27. Then the infrared sensor 26 detects the emitted red light reflected back, and then transmits the signal to the controller. The controller controls the alarm 28 to be energized, and emits an alarm sound and light to remind the workers of the shortage of materials.

[0025] In order to be able to adjust the pushing speed of the intermittent pushing mechanism according to the dispensing time of different materials, an upper travel switch 29 is fixedly connected to the top of the workbench 1 and is located next to the sliding block 13. An inwardly recessed moving groove 30 is opened on the top of the workbench 1. A threaded rod 31 is rotatably connected to the inner side of the moving groove 30. The outer wall of the threaded rod 31 passes through the bottom block 32 connected by the thread. It should be noted that, as can be seen from the accompanying drawings, a guide rod passing through the bottom block 32 is provided in the moving groove 30, so it will not rotate with the threaded rod 31, but will only move horizontally. The guide rod is a mature technology in the prior art and will not be described here. The bottom block 32 A lower travel switch 33 is fixedly connected to the top, and both the upper travel switch 29 and the lower travel switch 33 are electrically connected to the drive motor 10 through the controller. The upper transverse groove 19 and the lower transverse groove 20 are both provided with an elongated groove 43 flush with the lower clamping groove 22 on the side away from the conveyor line 9. By setting the elongated groove 43, the sliding of the positioning pin 18 can be guided when the position of the lower travel switch 33 is adjusted backward and the sliding distance of the sliding block 13 is increased, so as to avoid hindering the positioning pin 18 from continuing to slide backward and affecting the normal operation of the device, and the elongated groove 43 is flush with the lower clamping groove 22, so it will not hinder the normal operation of the positioning pin 18; The side wall of the threaded rod 31 passes through the workbench 1 and is fixedly connected to a rotating rod 34, the top of the bottom block 32 is fixedly connected to a pointer 35, a time scale groove 36 is opened at the top of the workbench 1 and at a position corresponding to the pointer 35, and the touch ends of the upper travel switch 29 and the lower travel switch 33 are both set at positions corresponding to the sliding block 13; When the intermittent feeding mechanism is running, the driving motor 10 is controlled to start and drive the sliding block 13 to move, and the nameplate is intermittently pushed and fed. When the sliding block 13 moves and touches the touch end of the upper stroke switch 29, the upper stroke switch 29 transmits a signal to the controller, and the controller controls the driving motor 10 to reverse, thereby driving the sliding block 13 to move backward and reset. Then, when it touches the lower stroke switch 33, the lower stroke switch 33 transmits a signal to the controller, and the controller controls the driving motor 10 to flip and drive the sliding block 13 to move forward. In this way, the reversal is realized to realize the intermittent push feeding of the luggage nameplate automatically. When the feeding speed needs to be adjusted according to the dispensing time of different luggage nameplates, the threaded rod 31 can be rotated by rotating the rotating rod 34, thereby driving the threaded bottom block 32 to move, and then the lower travel switch 33 moves. At the same time, the position of the pointer 35 on the time scale groove 36 can be observed, and the position of the lower travel switch 33 can be accurately adjusted, so that the backward position of the sliding block 13 can be changed, thereby lengthening the movement time of the sliding block 13, increasing the dispensing time, and realizing flexible adjustment of different dispensing times. The backward position of the push plate 17 is between the nameplates, so it will not push the nameplate to move backward.

[0026] In order to be able to automatically load bag nameplates of different lengths, an inwardly recessed adjusting groove 37 is provided on the top of the workbench 1, and a bidirectional screw 38 is rotatably connected to the inside of the adjusting groove 37, and a pair of pull blocks 39 are threadedly connected through the outer wall of the bidirectional screw 38. It should be noted that, as can be seen from the accompanying drawings, a guide rod penetrating the pull block 39 is provided inside the adjusting groove 37, so it will not rotate with the bidirectional screw 38, but will only move horizontally, and the guide rod is a mature technology in the prior art, which will not be described in detail here. The pull blocks 39 are all fixedly connected to the bottom of the fixed plate 5, and the front side of the bidirectional screw 38 passes through the workbench 1 and is fixedly connected to a hand wheel 40, and a length scale groove 41 is provided on the top of the workbench 1 and located next to the fixed plate 5; When dispensing glue on bag nameplates of different lengths and it is necessary to adjust the distance between the fixed plate 5 and the top plate 8, the bidirectional screw 38 is driven to rotate by rotating the hand wheel 40, thereby driving the two threaded pull blocks 39 to move toward or away from each other, and at the same time driving the fixed plate 5 and the top plate 8 to move, thereby realizing the adjustment of the distance between the fixed plate 5 and the top plate 8, and then the nameplates of different lengths can be automatically loaded, thereby improving the application range of the device.
