In this embodiment, the rotating shaft 41 is rotatably arranged in the mounting tube 3, and the rotating shaft 41 passes through the accommodating cavity 311, the shaft hole 321 and the second mounting hole 12 from top to bottom. For details, please continue to refer to Figure 1 and Figure 5 The first bearing 33, the bearing spacer sleeve 34 and the second bearing 35 are stacked in sequence in the accommodating cavity 311 of the cylinder 31. The first bearing 33 is supported on the upper surface of the bottom disc 32, the bearing spacer sleeve 34 is supported on the upper surface of the first bearing 33, and the second bearing 35 is supported on the upper surface of the bearing spacer sleeve 34. The rotating shaft 41 is composed of a first column 411, a second column 412 and a third column 413 from top to bottom. The diameter of the first column 411 is larger than the diameter of the second column 412, and the diameter of the second column 412 is larger than the diameter of the third column 413. Figure 1It can be seen that the lower surface of the first column 411 is supported on the upper surface of the second bearing 35, the second column 412 extends into the first bearing 33, the bearing spacer sleeve 34 and the second bearing 35, and the third column 413 passes through the second mounting hole 12. The carrier plate 5 can be fixed on the upper side of the top disc 42 so as to rotate synchronously with the transmission member 4. Here, see Figure 5 and 6 , Figure 6 A top view of the transmission member 4 provided in this embodiment is shown in FIG. Figure 5 and 6 As shown, the top disc 42 is provided with a racetrack-shaped positioning boss 421 on its upper side.

Figure 1 It can be seen that the runway-shaped positioning boss 421 is embedded in the slot 51. In addition, the carrier plate 5 and the top disc 42 are fastened by four countersunk screws, so that the carrier plate 5 can rotate synchronously with the transmission member 4. It should be understood that the upper side of the carrier plate 5 is used to support the rubber barrel. In this embodiment, the linkage assembly 6 is arranged on the lower side of the connecting base plate 1, and is respectively connected to the output shaft of the driver 2 and the rotating shaft 41 of the transmission member 4. For details, continue to refer to Figure 1 The linkage assembly 6 includes a first transmission wheel 61, a second transmission wheel 62 and a synchronous belt 63.

[0038] In summary, the driver 2 can drive the transmission member 4 to rotate by means of the linkage assembly 6, and the transmission member 4 can then drive the carrier plate 5 to rotate synchronously, so that the rubber barrel placed on the carrier plate 5 rotates with the carrier plate 5. In this way, it is only necessary to fix the barcode scanner at the height of the rubber barrel on the carrier plate 5. When the rubber barrel rotates with the carrier plate 5, the barcode scanner can scan the barcode on the side of the rubber barrel, so as to realize the automation of the rubber barrel scanning, greatly improve the working efficiency of barcode scanning, and further improve the cigarette production efficiency.

[0039] Furthermore, in this embodiment, the inner diameter of the second mounting hole 12 is larger than the outer diameter of the rotating shaft 41, and the bottom disc 32 of the mounting cylinder 3 can be connected to the connecting bottom plate 1 by sliding parallel to the connecting bottom plate. In this way, the tensioning and loosening of the synchronous belt 63 can be achieved by moving the mounting cylinder 3. Here, the bottom disc 32 and the connecting bottom plate 1 are connected by a first screw (not shown). For details, see Figure 4 The bottom disc 32 is provided with a first screw hole 322 which passes axially therethrough. Figure 2 The connecting bottom plate 1 is provided with a first guide hole 13 which is axially through and extends along the first direction. The first screw passes through the first screw hole 322 and the first guide hole 13 in sequence. The first screw is threadedly connected with the first screw hole 322. The first screw can only slide into the first guide hole 13 along the first direction. Figure 1 A bracket 71 is fixed to one end of the connecting base plate 1 close to the second mounting hole 12, and an adjusting rod 72 is mounted on the bracket 71 and can only rotate relative to the bracket 71. Fig. 9 and Fig.10 , Fig. 9 A front view schematic diagram of a bracket 71 provided in this embodiment, Fig.10 The left side schematic diagram of the bracket 71 provided in this embodiment is as follows Fig. 9 and Fig.10 As shown, the bracket 71 includes a first U-shaped mounting portion 711 with an opening toward the left and a second U-shaped mounting portion 712 with an opening toward the top. Figure 2 ,exist Figure 2 It can be seen that the right edge of the connecting bottom plate 1 is provided with a positioning opening groove 14, and the first U-shaped mounting portion 711 is inserted and fixed in the positioning opening groove 14 from right to left. The first U-shaped mounting portion 711 includes a parallel upper clamping piece 7111 and a lower clamping piece 7112, and the upper clamping piece 7111 and the lower clamping piece 7112 jointly clamp the bottom wall of the positioning opening groove 14. In addition, the upper clamping piece 7111 and the lower clamping piece 7112 are fastened to the bottom wall of the positioning opening groove 14 by screws. Figure 1When the first U-shaped mounting portion 711 is inserted and fixed in the positioning opening groove 14, the upper surface of the upper clip 7111 is flush with the upper surface of the connecting bottom plate 1. Fig. 9 and Fig.10 As shown, the second U-shaped mounting portion 712 includes a parallel left positioning piece 7121 and a right positioning piece 7122, wherein the left positioning piece 7121 is provided with a positioning groove 7121a with an opening facing upward, and the right positioning piece 7122 is provided with a clearance hole 7122a aligned with the positioning groove. Figure 4 The peripheral side wall of the bottom disc 32 is provided with an internal threaded hole 323, and the axial directions of the adjustment rod 72 and the internal threaded hole 323 are parallel to the first direction. In this embodiment, the adjustment rod 72 extends into the internal threaded hole 323 and is threadedly connected with the internal threaded hole 323. Specifically, back to Figure 1 The adjusting rod 72 includes a screw rod 721 with an external thread and a screw head 722 connected to the head of the screw rod 721. The screw rod 721 is horizontally placed in the positioning groove from top to bottom. The left end of the screw rod 721 extends into the internal threaded hole 323 of the bottom disc 32 and is threadedly connected to the internal threaded hole 323. The screw head 722 is clamped between the left positioning piece 7121 and the right positioning piece 7122 so that the adjusting rod 72 cannot move left and right relative to the bracket 71. The screw head 722 is also aligned with the clearance hole 7122a so that we can use a screwdriver to screw the adjusting rod 72 through the clearance hole 7122a. It should be understood that by screwing the adjusting rod 72, the mounting tube 3 can be driven to move left and right. The left and right movement of the mounting tube 3 can drive the right end of the synchronous belt 63 to move left and right through the transmission member 4, thereby realizing the tensioning and relaxation of the synchronous belt 63. In addition, it should be noted that, refer to Figure 1 The second transmission wheel 62 is sleeved on the lower end of the rotating shaft 41, and the upper end of the second transmission wheel 62 extends into the first mounting hole 11. The outer diameter of the upper end of the second transmission wheel 62 is smaller than the inner diameter of the second mounting hole 12, so that the second transmission wheel 62 will not touch the inner wall of the second mounting hole 12 when moving left and right with the transmission member 4, thereby preventing the mounting tube 3 from being obstructed when moving.

[0040] Further, in this embodiment, see Figure 3 A retaining ring groove 3111 is recessed on the upper portion of the inner surface of the accommodating cavity 311, and a hole retaining ring (not shown) is embedded in the retaining ring groove 3111. The lower surface of the hole retaining ring is flush with the upper surface of the second bearing 35, thereby improving the stability of the first bearing 33 and the second bearing 35 in the accommodating cavity 311.

[0041] Furthermore, in this embodiment, the linkage assembly 6 further includes a first stopper 64 and a second stopper. Figure 1 The outer diameter of the first blocking cover 64 is larger than the outer diameter of the first transmission wheel 61, and is fixed to the bottom of the first transmission wheel 61; the outer diameter of the second blocking cover 65 is larger than the outer diameter of the second transmission wheel 62, and is fixed to the bottom of the second transmission wheel 62; the lower edges of both ends of the synchronous belt 63 are respectively supported by the first blocking cover and the second blocking cover to prevent the synchronous belt 63 from falling off.

[0042] In summary, the implementation of the glue barrel scanning turntable of the present invention can at least achieve the following beneficial effects:

[0043] 1. The driver 2 can drive the transmission member 4 to rotate by means of the linkage assembly 6, and the transmission member 4 can then drive the carrier plate 5 to rotate synchronously, so that the plastic barrel placed on the carrier plate 5 rotates with the carrier plate 5. In this way, it is only necessary to fix the barcode scanner at the same height as the plastic barrel on the carrier plate 5. When the plastic barrel rotates with the carrier plate 5, the barcode scanner can scan the barcode on the side of the plastic barrel, thereby realizing the automation of plastic barrel scanning, greatly improving the working efficiency of barcode scanning, and thus improving the efficiency of cigarette production;

[0044] 2. By screwing the adjusting rod 72, the installation tube 3 can be driven to move left and right. The installation tube 3 can drive the right end of the synchronous belt 63 to move left and right through the transmission member 4, thereby achieving the tension and relaxation of the synchronous belt 63;

[0045] 3. A retaining ring groove 3111 is recessed on the upper portion of the inner surface of the accommodating cavity 311. A hole retaining ring is embedded in the retaining ring groove 3111. The lower surface of the hole retaining ring is flush with the upper surface of the second bearing 35, so that the stability of the first bearing 33 and the second bearing 35 in the accommodating cavity 311 can be improved;

[0046] 4. The outer diameter of the first stop cover 64 is larger than the outer diameter of the first transmission wheel 61, and is fixed to the bottom of the first transmission wheel 61; the outer diameter of the second stop cover 65 is larger than the outer diameter of the second transmission wheel 62, and is fixed to the bottom of the second transmission wheel 62; the lower edges of both ends of the synchronous belt 63 are respectively supported by the first stop cover and the second stop cover to prevent the synchronous belt 63 from falling off.
