DETAILED DESCRIPTION

[0022] The accompanying drawings needed to be used in the embodiments of the present application will be described below. Figures 1-7 The technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments only represent some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0023] Embodiment: As Figures 1 to 7 shown, the paper feeding positioning device of the folder gluer disclosed by the present application is mainly used in cooperation with the paper feeding conveying device at the front end of the folder gluer in actual application. The paper feeding conveying device is composed of a plurality of parallel transmission belts, and a transmission belt gap is reserved between adjacent transmission belts for accommodating the paper blocking plate and the rolling wheel in the device to realize the transverse limiting of the paperboard. The entire paper feeding positioning device is installed below the transmission belt 8, which is compact in structure and does not affect the original equipment space layout. The positions and gaps between the transmission belts are mainly set for several frequently produced paperboard specifications.

[0024] The device main body includes two side plates 1 arranged symmetrically left and right, which are fixed on the folder gluer rack as the basic support structure of the entire device. The two side plates 1 are slidably provided with movable plates 2 on the sides away from each other, and a guide rail extending upward and downward is arranged on the outer side of each side plate 1. The movable plate 2 is connected with the side plate 1 through a sliding block guide rail assembly to realize stable and reliable upward and downward movement. The two side plates 1 are each provided with a lifting mechanism for driving the movable plate 2 to move up and down, and the lifting mechanism specifically includes a cylinder 71, a cylinder fixing seat 72, and a cylinder connecting seat 73. The cylinder fixing seat 72 is fixed on the side plate 1 and located on the upper side of the movable plate 2, the cylinder 71 is fixed on the cylinder fixing seat 72, and the cylinder connecting seat 73 is fixed on the movable plate 2. The piston rod of the cylinder 71 is connected with the cylinder connecting seat 73. When the control system issues an adjustment instruction, the cylinder 71 drives the movable plate 2 to slide up and down along the guide rail, thereby controlling the overall lifting of the profile 3 installed therebetween. It should be noted that the two cylinders 71 should be kept synchronous, which can be achieved by using the same air source and parallel air supply circuit design, and setting a throttle valve (one-way throttle valve) for speed adjustment, and a position sensor can also be selected for monitoring. These means are well known to those skilled in the art.

[0025] Among them, the profile 3 is fixed horizontally between the two movable plates 2, which is a long strip-shaped aluminum alloy or steel profile 3. The two side plates 1 are each provided with a movable port 11 for the profile 3 to pass through and be fixedly connected with the movable plate 2. The size of the movable port 11 can allow the profile 3 to move up and down freely during lifting. Two paper blocking pieces are slidably arranged on the profile 3. A transverse driving mechanism is arranged between the two movable plates 2 for driving the two paper blocking pieces to move closer or farther away from each other.

[0026] The paper blocking member mainly comprises a sliding seat 41, a blocking block seat 42, a paper blocking plate 44 and a driving plate 48. The sliding seat 41 is slidably fitted on the profiled material 3. The sliding seat 41 and the profiled material 3 are slidably fitted through a sliding block guide rail assembly. The blocking block seat 42 is fixed on the front side of the sliding seat 41. The paper blocking plate 44 is installed on the blocking block seat 42. The driving plate 48 is fixedly connected on the rear side of the sliding seat 41 and is used for being matched with the transverse driving mechanism as a power input end of the transverse driving mechanism. The transverse driving mechanism specifically comprises a double-rotation thread screw rod 51, a speed reducer motor 52, a driving gear 53, a driven gear 54 and a motor mounting seat 55. The two ends of the double-rotation thread screw rod 51 are rotatably fitted between the two movable plates 2. The motor mounting seat 55 is fixed on one of the movable plates 2. The speed reducer motor 52 is installed on the motor mounting seat 55. The driving gear 53 is key-connected with the output shaft of the speed reducer motor 52. The driven gear 54 is connected on one end of the double-rotation thread screw rod 51 close to the driving gear 53 and is engaged with the driving gear 53. The nut seat 49 is fixedly connected on the driving plate 48. The left and right sides of the double-rotation thread screw rod 51 are respectively provided with threads of different rotation directions (one left-handed and one right-handed). The nut seats 49 on the two paper blocking members are respectively threadedly fitted on the threads of different rotation directions on the left and right sides of the double-rotation thread screw rod 51. Therefore, when the screw rod rotates, the two paper blocking members synchronously realize the movement of approaching or moving away from each other, so as to automatically adjust the distance between the two paper blocking plates 44 to adapt to the paperboard of different widths.

[0027] The paper blocking plate 44 is detachably installed on the blocking block seat 42. Specifically, the fixed plate 45 is fixedly connected on the paper blocking plate 44. The fixed plate connecting bayonet 43 is formed on the blocking block seat 42. The fixed plate connecting bayonet 43 comprises a lower transverse clamping groove 431, a through groove 432 located on the upper side of the lower transverse clamping groove 431 and an upper transverse clamping groove 433 located on the side of the through groove 432. The lower transverse clamping groove 431 and the upper transverse clamping groove 433 are used for installing the fixed plate 45. The through groove 432 is used for slidingly passing the fixed plate 45 to switch between the lower transverse clamping groove 431 and the upper transverse clamping groove 433. In normal operation, the fixed plate 45 is clamped into the lower transverse clamping groove 431, so that the paper blocking plate 44 is in a standard height position. When the equipment needs emergency treatment due to failure (such as failure of the lifting mechanism), the fixed plate 45 can be slid upward along the through groove 432 to the upper transverse clamping groove 433, so as to lift the paper blocking plate 44, so that the paper blocking plate 44 can continue to be used for positioning the paperboard. If the upper end of the paper blocking plate 44 originally interferes with the paper conveying path on the upper side of the conveying belt 8, the paper blocking plate 44 is first disassembled. After the distance between the two blocking block seats 42 is adjusted, the paper blocking plate 44 is installed again.

[0028] In addition, in order to enhance the connection strength, the stop block seat 42 is fixedly connected with a connecting plate 47 at the lower side of the lower transverse clamping groove 431 and the upper transverse clamping groove 433, the fixed plate 45 is provided with a bolt 46, and the connecting plate 47 is provided with a connecting opening 471 for the bolt 46 to pass through. The bolt 46 is locked after passing through the connecting opening 471 of the connecting plate 47, so as to be fixed and prevent loosening.

[0029] In order to further improve the paper feeding precision, a plurality of deviation correcting assemblies are arranged on the upper side of the profile 3 and used for dynamically correcting the deviated paperboard. Each deviation correcting assembly comprises a wheel frame 61 fixed on the upper side of the profile 3 and a rolling wheel 62 rotatably arranged on the wheel frame 61, and a deviation correcting driving mechanism is arranged on the profile 3 and used for driving the rolling wheel 62 to rotate. It should be noted that the rolling wheel 62 is located at the lower side of the upper end surface of the conveying belt 8 under normal circumstances, and only when deviation correction is needed, the cylinder 71 controls the movable plate 2 to continue to move upwards, so that the upper side of the rolling wheel 62 protrudes from the upper surface of the conveying belt 8. The paper feeding mechanism is provided with a sensor for sensing the position of the paperboard, which is well known to those skilled in the art. The control system judges the deviation direction and degree according to the deviation signal of the paperboard position detected by the front sensor, and determines whether to start the deviation correction action.

[0030] Further, the profile inner cavity 31 is arranged inside the profile 3, the profile 3 is provided with a belt opening 32 corresponding to the lower side of the rolling wheel 62 on the upper side, the shaft 63 is rotatably arranged on the inner side wall of the profile inner cavity 31 corresponding to the position of each rolling wheel 62, the pulley 64 is fixedly connected with the shaft 63, the belt groove 621 is arranged on the rolling wheel 62, the belt 65 is arranged between the pulley 64 and the belt groove 621, the deviation correcting driving mechanism is used for driving the shaft 63 to rotate, and the upper side of the rolling wheel 62 is lower than the upper end of the paperboard stopper 44.

[0031] The deviation correction driving mechanism comprises a rack 66 and a rack driving cylinder 67. The rack 66 is horizontally arranged in the profile inner cavity 31 in the profile 3 and is in sliding cooperation with the inner cavity bottom wall through a sliding block guide rail assembly. The rack driving cylinder 67 is fixed on one of the movable plates 2. The piston rod of the rack driving cylinder 67 penetrates into the profile inner cavity 31 and is connected with one end of the rack 66. The rotating shaft 63 is keyed with a deviation correction gear 68 for engaging with the rack 66. When deviation correction is needed, the movable plate 2 is first pushed upward by the cylinder 71 to make the upper end of the rolling wheel 62 slightly higher than the surface of the conveying belt 8. Then the rack driving cylinder 67 is actuated to push the rack 66 to move horizontally. The rack 66 engages with the deviation correction gear 68 fixed on the rotating shaft 63 to drive the rotating shaft 63 to rotate. The rotating shaft 63 is arranged in the profile inner cavity 31 and is provided with a belt pulley 64. The belt pulley 64 is connected with the belt groove 621 in the rolling wheel 62 through a belt 65 to drive the rolling wheel 62 to rotate. According to the deviation direction of the paperboard, the control system controls the rack 66 to move left or right to drive the rolling wheel 62 on the corresponding side to rotate forward or reversely. The paperboard is slightly adjusted to the center position by the friction force to accurately enter the paper feeding interval between the two paper stopping plates 44.

[0032] The working process of the whole device is as follows: when different specifications of paperboard are replaced, the control system controls the lifting mechanism to act according to the preset parameters or manual input instructions. The cylinder 71 drives the movable plate 2 to descend to drive the profile 3 and the paper stopping plate 44 to move downward as a whole below the conveying belt 8 to be separated from the working position. Then the transverse driving mechanism is started. The double-rotation-direction screw rod 51 is rotated to drive the two paper stopping pieces to be automatically adjusted to the target interval. After the adjustment is completed, the lifting mechanism is actuated again to lift the paper stopping plate 44 to the working height to make the upper end thereof extend to the upper side of the conveying belt 8 through the gap of the conveying belt 8 to complete the positioning preparation. In this process, if the paperboard is slightly deviated, the deviation correction assembly can intervene in real time to ensure that the paperboard smoothly enters the limiting interval.

[0033] The device realizes full-automatic operation of the paper feeding positioning process through the combination of mechanical structure and pneumatic and electric control system, significantly reduces manual intervention, improves the change type speed and production continuity. Meanwhile, the modular design is convenient for maintenance and replacement. The multiple safety and emergency mechanisms enhance the reliability and adaptability of the equipment and are suitable for modern packaging production requirements of multiple varieties and small batches.
