[0050] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0051] like Figures 1 to 6 As shown, this embodiment discloses a synchronous conveyor belt for medicine plates with automatically adjustable width, including a driving shaft 5 and a driven shaft 7. The driving shaft 5 is provided with a plurality of driving pulley assemblies 10, which are axially slidingly engaged with the driving shaft 5; the driven shaft 7 is provided with a plurality of driven pulley assemblies 11, which are slidably connected to the driven shaft 7; the driving pulley assemblies 10 and the driven pulley assemblies 11 correspond to each other one by one and are connected by a conveyor belt 14; each conveyor belt 14 is provided with an adjustment plate 4, and the two ends of the adjustment plate 4 are respectively connected to the driving pulley assembly 10 and the driven pulley assembly 11; each adjustment plate 4 is provided with a screw drive mechanism 9, which drives the adjustment plate 4 to move axially along the driving shaft 5. Starting the screw drive mechanism 9 can drive the adjustment plate 4 to move, thereby driving the driving pulley assembly 10, the driven pulley assembly 11 and the conveyor belt 14 to move, and then the width between the conveyor belts 14 can be adjusted.

[0052] In this embodiment, four adjusting plates 4 , four driving pulley assemblies 10 , four driven pulley assemblies 11 and four conveyor belts 14 are provided, and a maximum of four rows of medicine plates 13 can be conveyed.

[0053] The two ends of the driving shaft 5 are respectively rotatably connected to the two conveying arches 1. The two conveying arches 1 are arranged in parallel and are fixedly connected by the arch support shaft 2. One end of the arch support shaft 2 passes through one of the conveying arches 1 and is fixedly connected to the wall panel 12.

[0054] A plurality of linear guide shafts 3 are also provided between the two conveying arches 1. The adjustment plate 4 is slidingly connected to the linear guide shaft 3 through a flange linear bearing 8, so that the adjustment plate 4 can slide axially along the linear guide shaft 3. At the same time, the linear guide shaft 3 plays an auxiliary guiding role for the adjustment plate 4.

[0055] One end of the drive shaft 5 passes through one of the conveyor arches 1 and connects to the conveyor drive 6. Specifically, the conveyor arch 1 is provided with a pre-set hole with a diameter larger than that of the drive shaft 5. After passing through the pre-set hole, the drive shaft 5 is dynamically connected to the conveyor drive 6. The conveyor drive 6 drives the drive shaft 5 to rotate, thereby driving the driving pulley assembly 10, the conveyor belt 14, and the driven pulley assembly 11 to rotate, thereby achieving conveying operation. In this embodiment, the conveyor drive 6 and the screw drive mechanism 9 are both mounted on the wall panel 12.

[0056] like Figures 4 and 5 As shown, in this embodiment, a plurality of card plates 14 - 2 are arranged at intervals on the conveyor belt 14 , and the medicine plate 13 is placed between the card plates 14 - 2 . When the conveyor belt 14 rotates, the card plates 14 - 2 can generate thrust on the medicine plate 13 .

[0057] In this embodiment, removable slides 14-1 are provided on both sides of the conveyor belt 14. The slides 14-1 are symmetrically distributed on both sides of the conveyor belt 14, and the width between the two slides 14-1 matches the medicine plate 13. The slides 14-1 are removably connected to the support plate 1-1 via a bolt assembly. The support plate 1-1 is located between the gap between the conveyor belt 14 and the adjustment plate 4. The two ends of the support plate 1-1 are fixedly connected to the two conveyor arches 1, wherein the support plate 1-1 is provided with a mounting groove, and the slides 14-1 are connected to the mounting groove via a bolt assembly. The top surface of the bottom plate of the slide 14-1 is flush with the top surface of the conveyor belt 14. After the width between adjacent conveyor belts 14 is adjusted, the slides 14-1 are connected to the support plate 1-1 via a bolt assembly, and the medicine plate 13 is placed on the slides 14-1, so that the slides 14-1 serve as a limiting guide for the medicine plate 13, preventing the medicine plate 13 from deviating left or right.

[0058] like Figure 4 Combine Figure 8As shown, in this embodiment, both conveyor arches 1 are provided with driven shaft mounting grooves 1-2, and the two ends of the driven shaft 7 are respectively arranged in the driven shaft mounting grooves 1-2 and fixed by bolt assemblies. The driven shaft mounting grooves 1-2 are arranged in an elongated strip shape. After loosening the bolt assemblies, the position of the driven shaft 7 can be adjusted, thereby adjusting the tension of the driving pulley assembly 10, the conveyor belt 14 and the driven pulley assembly 11. After the position is adjusted appropriately, the bolt assembly is tightened to fasten the driven shaft 7 to the conveyor arch 1. Specifically, a first reserved hole 7-1 is provided at the end of the driven shaft 7, and a second reserved hole 1-3 is provided on the conveyor arch 1 at a position corresponding to the driven shaft mounting groove 1-2. The driven shaft 7 can be pulled by passing the bolts through the first reserved hole 7-1 and the second reserved hole 1-3 and tightening them with nuts, thereby tensioning the conveyor belt 14.

[0059] like Figures 4 to 8 As shown, the screw drive mechanism 9 includes a driver 9-1, an adjustment screw 9-2, and an adjustment nut 9-3. In this embodiment, driver 9-1 utilizes a German HALSTRUP-WALCHER mechanical automatic positioning system, comprising a motor, motor amplifier, hollow shaft, control unit, absolute measurement system, serial interface, and gears. In this embodiment, driver 9-1 is equivalent to a servo motor capable of precise positioning. Driver 9-1 is mounted on a wall panel 12. A reserved hole is provided in the wall panel 12, through which one end of the adjustment screw 9-2 can be movably inserted and connected to the output shaft of driver 9-1.

[0060] A reserved hole is provided in the adjustment plate 4, and the side wall around the reserved hole of the adjustment plate 4 is fixedly connected to the adjusting nut 9-3. The adjusting screw 9-2 is threadedly connected to the adjusting nut 9-3 and passes through the reserved hole of the adjustment plate 4. One end of the adjusting screw 9-2 can be rotatably passed through one of the conveying arches 1 and then connected to the driver 9-1 for power, and the other end of the adjusting screw 9-2 is rotatably connected to the other conveying arch 1.

[0061] The number of the drivers 9 - 1 is the same as the number of the adjustment plates 4 , and the drivers 9 - 1 and the adjustment plates 4 are matched one-to-one.

[0062] When the driver 9-1 is started, it drives the adjusting screw 9-2 to rotate and can be precisely positioned, so that the adjusting nut 9-3 and the adjusting plate 4 slide left and right under the guidance of the linear guide shaft 3, thereby achieving width adjustment between the conveyor belts 14.

[0063] like Figures 7 to 11As shown, in this embodiment, each adjustment plate 4 is provided with two mating adjustment screws 9-2, one on each side of the adjustment plate 4. The two adjustment screws 9-2 are rotatably connected to the conveyor arches 1 on either side at both ends. One end of the other adjustment screw 9-2 is rotatably connected to one of the conveyor arches 1, while the other end passes through the other conveyor arch 1 and is fixedly connected to the output shaft of the driver 9-1. Both mating adjustment screws 9-2 are provided with sprockets 9-4, and the sprockets 9-4 of the two adjustment screws 9-2 are connected by a chain 9-5. When the driver 9-1 drives one adjustment screw 9-2 to rotate, the chain 9-5 and sprocket 9-4 drive the other adjustment screw 9-2 to rotate synchronously, thereby ensuring smooth and synchronized sliding of the two ends of the adjustment plate 4.

[0064] The conveying drive device 6 includes a motor 6-1, which is connected to a reducer 6-2. The output end of the reducer 6-2 is connected to the driving shaft 5 through a coupling 6-3. The motor 6-1 and the reducer 6-2 are mounted on the wall panel 12 through a frame. When the motor 6-1 is started, the driving shaft 5 can be driven to rotate.

[0065] like Figures 9 to 12 As shown, the driving pulley assembly 10 includes a driving pulley 10-1, which is fixedly connected to the outer wall of one end of the driving pulley connecting seat 10-2. Specifically, a bolt mounting groove is provided on the driving pulley 10-1, and a threaded hole is provided on the side wall of the driving pulley connecting seat 10-2. The bolt is passed through the bolt mounting groove on the driving pulley 10-1 and screwed into the threaded hole on the driving pulley connecting seat 10-2 and tightened, so that the driving pulley 10-1 and the driving pulley connecting seat 10-2 are fastened together by the bolts. The driving pulley connecting seat 10-2 is sleeved on the driving shaft 5, and the driving shaft 5 is provided with a first slider 5-1. The driving pulley connecting seat 10-2 is provided with a first slide 10-2-1. The first slide 10-2-1 is slidably connected and cooperated with the first slider 5-1, so that the driving pulley connecting seat 10-2 can slide axially along the driving shaft 5, and the driving shaft 5 can also synchronously drive the driving pulley connecting seat 10-2 and the driving pulley 10-1 to rotate.

[0066] A reserved hole is provided on the adjustment plate 4, and the outer wall of the other end of the driving wheel connecting seat 10-2 is arranged in the reserved hole of the adjustment plate 4 with the help of a bearing, which can rotate relatively but not slide axially. When the adjustment plate 4 slides, it can slide with the driving wheel connecting seat 10-2.

[0067] The driven pulley assembly 11 includes a driven wheel 11-1, which is rotatably connected to the outer wall of one end of a driven wheel connecting seat 11-2 via a bearing. The driven wheel 11-1 cannot slide axially relative to the driven wheel connecting seat 11-2, and the driven wheel connecting seat 11-2 is sleeved on the driven shaft 7. A second slider 7-2 is provided on the driven shaft 7, and a second slide groove 11-2-1 is provided in the driven wheel connecting seat 11-2. The second slide groove 11-2-1 is slidably connected and cooperates with the second slider 7-2. A reserved hole is provided on the adjustment plate 4, and the other end of the driven wheel connecting seat 11-2 is disposed in the reserved hole of the adjustment plate 4 and is fixedly connected by a bolt assembly. In this way, the driven wheel 11-1 can rotate on the driven wheel connecting seat 11-2, and the adjustment plate 4 can drive the driven wheel connecting seat 11-2 and the driven wheel 11-1 to move axially.

[0068] like Figure 10 As shown, in this embodiment, the driving wheel connecting seat 10-2 has a large diameter end on one axial side and a small diameter end on the other. A threaded hole is formed in the sidewall of the large diameter end of the connecting seat 10-2 and is fastened to the driving wheel 10-1 via bolts. The outer wall of the small diameter end of the connecting seat 10-2 is connected to the adjustment plate 4 via a bearing. An annular boss is provided in the middle of the driven wheel connecting seat 11-2. The outer wall of one side of the annular boss end of the driven wheel connecting seat 11-2 is rotationally connected to the driven wheel 11-1 via a bearing. The outer wall of the other side of the annular boss end of the driven wheel connecting seat 11-2 is fastened to the adjustment plate 4 via a bolt assembly.

[0069] like Figure 9 As shown, a track 4 - 1 is fixedly connected to the edge of the adjustment plate 4 through a bolt assembly, and the conveyor belt 14 is slidably set in the track 4 - 1, so that the track 4 - 1 plays a limiting role on the conveyor belt 14.

[0070] like Figure 11 , which is a schematic structural diagram of the driving shaft 5 and the driven shaft 7.

[0071] like Figure 12 The figure shows the schematic diagram of the device working in conjunction with the manipulator.

[0072] like Figure 13 As shown, this is a working effect diagram of the device carrying four-plate medicine plates 13 in operation after the conveyor belt 14 position is moved by the adjustment plate 4;

[0073] like Figure 14 As shown, this is a working effect diagram of the device carrying the three-plate medicine plate 13 in operation after the conveyor belt 14 position is moved by the adjustment plate 4.

[0074] like Figures 1 to 15 As shown, the working principle of the present invention is as follows:

[0075] First, stop the motor 6-1 and start the driver 9-1. The driver 9-1 drives an adjusting screw 9-2 to rotate. The adjusting screw 9-2 drives another matching adjusting screw 9-2 to rotate synchronously with the help of the chain 9-5 and sprocket 9-4, thereby driving the adjusting nut 9-3 on the adjusting screw 9-2, the adjusting plate 4 on the linear guide shaft 3, the driving wheel 10-1 and the driven wheel 11-1 on the driving shaft 5 and the driven shaft 7, respectively, so that the conveyor belt 14 slides precisely to the desired position, that is, drives the corresponding conveyor belt 14 to adjust the position. Similarly, adjust the remaining adjusting plates 4 and conveyor belts 14 to the desired positions. After all adjustments are completed, the slide 14-1 is installed symmetrically with the conveyor belt 14 on the support plate 1-1. At this point, the width of the adjacent conveyor belts 14 is adjusted, and the motor 6-1 can be started. The rotation of the motor 6-1 drives the driving shaft 5, the driving wheel 10-1, and the conveyor belt 14 to rotate, and the conveying operation begins.

[0076] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by persons skilled in the art should fall within the scope of protection defined by the claims of the present invention.
