[0074] Furthermore, it also includes a plurality of installation frames 4, which are respectively arranged on the top of the installation bracket 1 and located above the corresponding external corner-adjusting mechanism 100; and a plurality of fine-tuning mechanisms 5, which are used to enable the corresponding lifting mechanism 3 to be slidably installed in the installation frame 4.

[0075] Furthermore, the lifting mechanism 3 includes a vertical plate 31, which is installed on the fine-tuning mechanism 5 and has an external fixed block 32 on its outer wall; a lifting slide groove 33, which is arranged on the outer side of the external fixed block 32 and slidingly cooperates with the lifting push rod 2; a pair of pulleys rotatably installed on the other side of the vertical plate 31 and connected by a transmission belt 34, one of which is connected to a driving motor; a vertical groove 35, which is vertically arranged on the vertical plate 31 and has a lifting rod 36 slidably provided inside, one end of which is fixed to the lifting push rod 2 and the other end of which is fixed to one side of the transmission belt 34.

[0076] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the number of lifting push rods 2 and the corner pasting mechanism corresponds to the number of corners of the carton, the external transport mechanism moves the carton sheet to be pasted between each lifting push rod 2 and each corner pasting mechanism, each driving motor is actuated to rotate the corresponding transmission belt 34 on the corresponding pair of pulleys, the corresponding lifting rod 36 drives the corresponding lifting push rod 2 to descend, abuts against the corner position of the carton sheet, and then pushes the carton sheet down to the working range of each corner pasting mechanism, each corner pasting mechanism performs corner pasting operation on the carton sheet, each lifting push rod 2 can move together with the corner pasting mechanism to adapt to carton sheets of different sizes, and then adjust through the corresponding fine-tuning mechanism 5 to adapt to different carton sheet thicknesses;

[0077] The corner-fixing mechanism is a prior art and will not be described in detail.

[0078] Embodiment 2:

[0079] like Figure 2As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the fine-tuning mechanism 5 includes a pair of internal fixing blocks 51, which are symmetrically arranged on the opposite inner walls of the mounting frame 4; a pair of transverse slide rails 52, which are slidably installed on the opposite side walls of each internal fixing block 51 through corresponding transverse slide grooves, and a support block 53 is fixed between the outer ends; a driving device 6, which is in transmission cooperation with the support block 53 and is used to adjust the position of the support block 53 in the mounting frame 4, the vertical plate 31 is fixed on the support block 53, and the motor is fixed on the support block 53 through the support plate.

[0080] Furthermore, the driving device 6 includes a screw hole 61, which is arranged on the inner wall of the support block 53; a screw rod 62, which is transmission-connected to the screw hole 61 and is rotatably mounted on the rear end of the mounting frame 4 through a bearing; a hand wheel 63, which is mounted on the end of the screw rod 62 away from the support block 53, and a locking mechanism 7 is provided between the screw rod 62 and the rear end wall of the mounting frame 4.

[0081] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when it is necessary to adjust the spacing between the lifting push rod 2 and the corresponding corner pasting mechanism to adapt to cardboards with different sheet thicknesses, the screw 62 is rotated by the hand wheel 63, and the screw 62 cooperates with the screw hole 61 to push the support block 53 and each horizontal slide rail 52 to move along the extension direction of the mounting frame 4, and then the locking mechanism 7 fixes the screw 62 so that the screw 62 cannot rotate, thereby ensuring that the position of the lifting push rod 2 no longer changes, avoiding the vibration generated by the operation of the equipment causing the relative position of the lifting push rod 2 and the corresponding corner pasting mechanism to change, and being unable to adapt to the current carton sheet thickness. Accordingly, the spacing between the lifting push rod 2 installed on each support block 53 through the vertical plate 31 and the corresponding corner pasting mechanism is adjusted to adapt to carton sheets of different thicknesses.

[0082] Embodiment 3:

[0083] like Figures 3 to 7 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the locking mechanism 7 includes a floating sleeve 71, which is fixedly mounted at the center of the inner wall of the hand wheel 63 and slidably sleeved on the end of the screw 62; a circular ring 72, which is fixedly mounted on the outer wall of the rear end of the mounting frame 4 and is concentric with the screw 62; a circular shell 73, which is rotatably mounted in the circular ring 72, is open toward the hand wheel 63 end, and the other end wall is fixedly connected to the screw 62, and a pair of side grooves 74 are symmetrically provided on the peripheral wall; a pair of sliding blocks 75 are slidably mounted in each side groove 74, and the inner ends extend into the circular shell 73; a transmission mechanism 8, which is used to make a pair of sliding blocks 75 transmission-connected with the floating sleeve 71, and when the floating sleeve 71 approaches / moves away from the inner end surface of the circular shell 73, the outer ends of the pair of sliding blocks 75 extend out / retract into the side grooves 74.

[0084] Furthermore, the locking mechanism 7 further comprises a reset annular groove 77 which is arranged on the end surface of the floating sleeve 71 ; a reset spring 78 which is installed in the reset annular groove 77 and has its outer end abutting against the inner end wall of the circular shell 73 .

[0085] Furthermore, the locking mechanism 7 also includes a pair of reset grooves 79, which are respectively arranged at the bottom of each of the side grooves 74 and extend toward the center of the inner end surface of the circular shell 73; a pair of reset plates 710, which can be slidably installed in each reset groove 79, and are fixedly connected to the outer end of the corresponding sliding block 75, and a reset tension spring 711 is fixedly arranged between the inner wall and the inner end of the corresponding reset groove 79.

[0086] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when it is necessary to release the fixed state of the screw rod 62, the hand wheel 63 is pressed toward the inner end of the circular shell 73, the transmission mechanism 8 is away from the sliding blocks 75, the return spring 78 is compressed and shortened, and each return spring 711 pulls the corresponding sliding block 75 into the corresponding side groove 74. At this time, turning the hand wheel 63 can drive the screw rod 62 to rotate. When it is necessary to fix the screw rod 62 again, the pressure on the hand wheel 63 is released, the return spring 78 releases the elastic potential energy, and pushes the hand wheel 63 to move out of the circular shell 73. The transmission mechanism 8 pushes each sliding block 75 so that the outer end of each sliding block 75 extends out of the side groove 74 and abuts against the inner wall of the ring 72. The return springs 711 are extended, and the screw rod 62 cannot rotate at this time.

[0087] The floating sleeve 71 and the peripheral wall of the screw rod 62 are slidably matched through splines and keyways, and the floating sleeve 71 can only slide along the axial direction of the screw rod 62;

[0088] In order to increase the friction between the outer end surface of each sliding block 75 and the inner circumferential wall of the ring 72 , a rubber gasket can be provided outside each sliding block 75 , and knurling can be provided on the inner circumferential wall of the ring 72 .

[0089] Embodiment 4:

[0090] like Figures 4 to 7 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the locking mechanism 7 also includes a socket 712, which is arranged on the end face of the peripheral wall of the open end of the circular shell 73 and is provided with an outer ring groove 713 inside; an insertion rod 714, which is fixed on the inner side wall of the hand wheel 63 and slidably inserted in the socket 712; a blind hole 715, which is arranged on the outer side wall of the hand wheel 63 and extends into the insertion rod 714; a pair of notches 716, which are symmetrically arranged on the peripheral wall of the insertion rod 714 and connected to the blind hole 715; a pressure rod 717, which is slidably installed in the blind hole 715 and is provided with a clamping spring 718 at the inner end; an inner ring groove 719, which is arranged at the inner end of the pressure rod 717; a pair of steel balls 720, which are movably installed in the pair of notches 716 and can enter the outer ring groove 713 or the inner ring groove 719.

[0091] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the hand wheel 63 approaches the inner end of the round shell 73, the insertion rod 714 penetrates into the blind hole 715 until the inner end of the floating sleeve 71 contacts the inner end surface of the round shell 73, each notch 716 corresponds to the outer ring groove 713, and the compression spring 718 releases its elastic potential energy to push the pressure rod 717 to slide outward from the blind hole 715, so that the outer sides of a pair of steel balls 720 are stuck in the corresponding outer ring grooves 713. The inner sides of the pair of steel balls 720 are now tightly pressed against the outer peripheral wall of the pressure rod 717. At this time, the floating sleeve 71 and the hand wheel 63 are fixed relative to the round shell 73, so that the hand wheel 63 and the floating sleeve 71 cannot move away from the round shell 73. At this time, each sliding block 75 is After the screw 62 is retracted into the corresponding side groove 74, the screw 62 can be rotated by simply turning the hand wheel 63, so that people do not need to press the hand wheel 63 and turn the hand wheel 63 at the same time. After the adjustment is completed, when the screw 62 needs to be fixed, the pressure rod 717 is pressed to make the inner end of the pressure rod 717 penetrate into the blind hole 715, and the compression spring 718 is compressed to store elastic potential energy until the inner ring groove 719 moves to correspond to each notch 716. At this time, the reset spring 78 releases the elastic potential energy, pushing the floating sleeve 71, the hand wheel 63 and the pressure rod 717 to move away from the round shell 73, and each steel ball 720 is squeezed into the inner ring groove 719 and separated from the outer ring groove 713. Each notch is also away from the outer ring groove 713. At this time, the position of the pressure rod 717 is fixed;

[0092] The inner end of the pressure rod 717 has a circle of annular protrusions, so that when it slides toward the outside of the blind hole 715, it can push each steel ball 720 toward the outside of the notch 716. When the outer side of each steel ball 720 is inserted into the outer ring groove 713, the inner side of each steel ball 720 remains in contact with the annular protrusion at the inner end of the pressure rod 717 to prevent the pressure rod 717 from escaping from the blind hole 715. When the outer side of each steel ball 720 is tightly pressed against the inner wall of the blind hole 715, the inner side is located in the inner ring groove 719, and is now away from the annular protrusion at the inner end of the pressure rod 717.

[0093] Embodiment 5:

[0094] like Figures 4 to 7 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the transmission mechanism 8 includes a limiting ring groove 81, which is arranged at the inner end of the circular shell 73 and is connected to a pair of side grooves 74; a rotating sleeve 82, which is rotatably sleeved on the outside of the floating sleeve 71; a pair of transmission spiral grooves 83, which are arranged at intervals on the peripheral wall of the rotating sleeve 82; a pair of transmission sliding blocks 84, which are symmetrically fixed on the outer peripheral wall of the floating sleeve 71 and slideably cooperate with the corresponding transmission spiral grooves 83; a pair of shifting grooves 85, which are respectively arranged on the side walls of each sliding block 75 facing the rotating sleeve 82; a pair of shifting blocks 86, which are symmetrically fixed on the outer peripheral wall of the rotating sleeve 82 and slideably cooperate with the limiting ring grooves 81 and the corresponding shifting grooves 85.

[0095] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the transmission sleeve moves toward the inner end of the circular shell 73, each transmission slider 84 slides from the end of the corresponding transmission spiral groove 83 close to the inner end of the circular shell 73 to the end away from the inner end of the circular shell 73, driving the rotating sleeve 82 to rotate relative to the transmission sleeve, and a pair of shifting blocks 86 enter the shifting groove 85 from the limiting ring groove 81 and push the corresponding sliding block 75 to slide outward of the side groove 74, and each reset spring 711 extends. Conversely, when the transmission block moves away from the inner end of the circular shell 73, each transmission slider 84 slides from the end of the corresponding transmission spiral groove 83 away from the inner end of the circular shell 73 to the end close to the inner end of the circular shell 73, driving the rotating sleeve 82 to rotate in the opposite direction relative to the transmission sleeve, and each shifting block 86 disengages from the corresponding shifting groove 85 and returns to the limiting ring groove 81. Each reset spring 711 is reset under its own elastic action, driving each sliding block 75 to retract the corresponding side groove 74.
