[0023] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] The present application provides a device for adjusting the width of a medicine bottle conveyor belt, the structure of which is as follows: Figure 1 - Figure 3 As shown, it includes a limiting mechanism 1 and an adjusting mechanism 2.

[0025] The limiting mechanism 1 includes an inner limiting belt 11 and an outer limiting belt 12. The inner limiting belt 11 is fixedly connected to the inner bend of the frame of the turning belt conveyor, and the outer limiting belt 12 is arranged on the outer bend of the frame of the turning belt conveyor. Both ends of the outer limiting belt 12 are fixedly connected to the conveying frame.

[0026] The adjusting mechanism 2 is provided on the conveying frame, and is used to adjust the curvature of the outer limiting belt 12 , thereby changing the distance between the outer limiting belt 12 and the inner limiting belt 11 .

[0027] A curved belt conveyor consists of a frame, conveyor belt, driving pulley, driven pulley, bearings, and couplings. Its operating principle is that the rotation of the driving pulley drives the synchronous rotation of the driven pulley, thereby forming a specific bend radius on the conveyor belt, enabling the material to be conveyed around a curve. Specifically, the driving pulley is driven by a motor and a reducer, while the driven pulley is connected to the driving pulley via bearings and couplings, forming a pair of transmission pairs. The conveyor belt is installed between the driving and driven pulleys. Driven by the driving pulley, the conveyor belt forms a specific bend radius, thereby conveying the material around a curve.

[0028] When in use, the inner limiting belt 11 is fixedly connected to the inner side of the corner of the conveyor frame. Its function is to provide an inner boundary limit for the medicine bottle on the conveyor belt to prevent the medicine bottle from excessively deflecting inward during transportation. The outer limiting belt 12 is set on the outer side of the corner of the conveyor frame, and its two ends are fixedly connected to the conveyor frame. The outer limiting belt 12 cooperates with the inner limiting belt 11 to provide an outer boundary limit for the medicine bottle, ensuring that the medicine bottle remains within a certain width range during transportation. The adjustment mechanism 2 is set on the conveyor frame and can adjust the curvature of the outer limiting belt 12. When the adjustment mechanism 2 adjusts the curvature of the outer limiting belt 12, the distance between the outer limiting belt 12 and the inner limiting belt 11 will change. If the curvature of the outer limiting belt 12 is increased, the outer limiting belt 12 will bend outward, thereby increasing the distance; conversely, if the curvature of the outer limiting belt 12 is reduced, the distance will decrease. This medicine bottle conveyor belt width adjustment device realizes flexible adjustment of the width of the medicine bottle conveyor belt through the cooperation of the limiting mechanism 1 and the adjustment mechanism 2, adapts to different medicine bottle sizes, prevents medicine bottle deviation, improves conveying accuracy, is convenient and quick to operate, and provides reliable guarantee for the transportation and production of medicine bottles.

[0029] In the present application, the distance between the outer limit belt 12 and the inner limit belt 11 is adjusted by the adjustment mechanism 2, which can adapt to medicine bottles of different sizes. Whether it is a medicine bottle with a smaller diameter or a medicine bottle with a larger diameter, the distance can be adjusted to ensure that the medicine bottle is stably conveyed on the turning belt conveyor, thereby improving the versatility of the turning belt conveyor. Accurate width adjustment can make the medicine bottles more neatly arranged on the turning belt conveyor, thereby improving the conveying accuracy, which is very important for subsequent packaging, filling and other processes, and can reduce errors and improve product quality.

[0030] To adjust the distance between the inner limit belt 11 and the outer limit belt 12, please refer to Figure 1 In a preferred embodiment, the adjustment mechanism 2 includes a cylinder 21 provided on the frame, and the piston rod of the cylinder 21 is connected to the side of the outer limiting belt 12 away from the frame.

[0031] During use, when width adjustment is not being performed, the cylinder 21 is in its initial position, and the piston rod is neither extended nor retracted. The distance between the outer limiting belt 12 and the inner limiting belt 11 is maintained at a specific initial value to accommodate the conveying of medicine bottles of a certain size. When the conveyor belt width needs to be adjusted to accommodate medicine bottles of different sizes, the control system activates the cylinder 21. The gas pressure within the cylinder 21 changes, pushing the piston rod outward or inward. The movement of the piston rod directly acts on the side of the outer limiting belt 12 away from the conveyor frame. When the piston rod extends, it applies an outward pull on the outer limiting belt 12, increasing the curvature of the outer limiting belt 12 and thereby increasing the distance between the outer limiting belt 12 and the inner limiting belt 11. Conversely, when the piston rod retracts, it applies an inward pull on the outer limiting belt 12, decreasing the curvature of the outer limiting belt 12 and, consequently, the distance. By adjusting the distance between the outer limiting belt 12 and the inner limiting belt 11, the curved belt conveyor can accommodate medicine bottles of different sizes. During the transportation process, the medicine bottles are restricted by the inner limiting belt 11 and the outer limiting belt 12 within a suitable width range to ensure stable transportation.

[0032] In order to make the curvature of the outer limit band 12 more uniform, please refer to Figure 2 In a preferred embodiment, the piston rod end is hinged with a plurality of support rods 22 , and the ends of the plurality of support rods 22 are hinged to the outer limiting band 12 at intervals along the length direction of the outer limiting band 12 .

[0033] During use, when the width of the conveyor belt needs to be adjusted, the control system starts the cylinder 21. The piston rod of the cylinder 21 begins to extend or retract. Since a plurality of support rods 22 are hinged to the end of the piston rod, when the piston rod moves, the support rods 22 will be driven to move accordingly. When the piston rod extends, it will push the support rods 22 to expand outward. The other end of the support rod 22 is hinged to the outer limiting belt 12 at intervals along the length direction of the outer limiting belt 12, so the expansion of the support rod 22 will apply an outward pulling force to the outer limiting belt 12, causing the curvature of the outer limiting belt 12 to increase. When the piston rod retracts, it will pull the support rods 22 inward. Similarly, the movement of the support rod 22 generates an inward pulling force on the outer limiting belt 12, causing the curvature of the outer limiting belt 12 to decrease. Multiple support rods 22 are hinged to the outer limiting belt 12 at intervals along the length direction of the outer limiting belt 12, forming a multi-point support structure. This structure can make the outer limiting belt 12 bear the force more evenly during the process of adjusting the curvature, thereby avoiding local deformation or instability.

[0034] In order to make the force of the outer limit belt 12 more uniform, please refer to Figure 2 In a preferred embodiment, a pad 23 is hinged at the end of the support rod 22 , and the pad 23 is connected to the outer limiting belt 12 .

[0035] When in use, the pad 23 is connected to the outer limiting band 12. Compared with directly connecting the end of the support rod 22 to the outer limiting band 12, the pad 23 increases the contact area with the outer limiting band 12. This can more evenly transmit the force of the support rod 22 to the outer limiting band 12, avoid local stress concentration, and reduce damage to the outer limiting band 12.

[0036] To adjust the curvature of the outer limit band 12, please refer to Figure 2 In a preferred embodiment, the support rod 22 is a telescopic rod with a telescopic function.

[0037] During use, the telescopic function of the telescopic rod allows the length of the support rod 22 to vary within a certain range, thereby increasing the adjustable range of the curvature of the outer limiting band 12. The distance between the outer limiting band 12 and the inner limiting band 11 can be more accurately adjusted according to the requirements of different medicine bottle sizes.

[0038] To adjust the length of the telescopic rod, please refer to Figure 2 In a preferred embodiment, the support rod 22 includes a first rod body 221 and a second rod body 222. The second rod body 222 is slidably connected to the first rod body 221 along the length direction of the first rod body 221. The end of the first rod body 221 is connected to the piston rod, and the end of the second rod body 222 is connected to the pad 23. The first rod body 221 is provided with a fixing component 3 for fixing the second rod body 222.

[0039] When in use, to adjust the length of the telescopic rod, push the second rod 222 to slide along the length direction of the first rod 221 , slide the second rod 222 to a predetermined position, and then use the fixing assembly 3 to fix the second rod 222 .

[0040] In order to fix the second rod 222, please refer to Figure 3 In a preferred embodiment, the fixing assembly 3 includes a socket 31 provided on the first rod body 221, an insertion rod 32 is passed through the socket 31, and a plurality of slots 33 for accommodating the insertion rod 32 are provided on the second rod body 222 along the length direction of the second rod body 222.

[0041] During use, before length adjustment and fixation are performed, the insertion rod 32 is not inserted into any slot 33. The first rod 221 and the second rod 222 are in a relatively slidable state, allowing the length of the support rod 22 to be adjusted as needed. The operator slides the second rod 222 along the length of the first rod 221 as needed. During this process, the insertion rod 32 separates from the slot 33, which does not affect the sliding of the second rod 222. When the second rod 222 reaches the desired position, the sliding operation is stopped. The operator observes the multiple slots 33 on the second rod 222 and selects a slot 33 that corresponds to the current position. This slot 33 will accommodate the insertion rod 32, thereby fixing the position of the second rod 222. The insertion rod 32 is inserted into the insertion hole 31 on the first rod 221, passing through the insertion hole 31 and into the selected slot 33. When the insertion rod 32 is fully inserted into the slot 33, the relative position between the first rod 221 and the second rod 222 is fixed. This fixing assembly 3 realizes the adjustability and fixing function of the length of the support rod 22 through the cooperation between the insertion rod 32 and the slot 33, providing a guarantee for the flexible use of the width adjustment device of the medicine bottle conveyor belt.

[0042] To improve the stability of the rod 32, please refer to Figure 3 In a preferred embodiment, a spring is provided on the insertion rod 32, one end of the spring is connected to the insertion rod 32, and the other end of the spring is connected to the first rod body 221. The spring is in a stretched state, and the spring causes the insertion rod 32 to have a tendency to slide toward the second rod body 222.

[0043] During use, when no operation is being performed, the spring mounted on the rod 32 is in a stretched state. One end of the spring is connected to the rod 32, and the other end is connected to the first rod 221. Due to the stretching action of the spring, the rod 32 exerts a force that tends to slide toward the second rod 222. When sliding the second rod 222, the rod 32 must overcome the tension of the spring. The operator applies a force greater than the spring's tension, causing the rod 32 to withdraw from its current slot 33 and maintain contact with the surface of the second rod 222 as the second rod 222 slides. During the sliding process, the spring remains in a stretched state, continuously exerting a pulling force on the rod 32 toward the second rod 222. This forces the rod 32 to move toward the second rod 222 during the sliding process. Once the second rod 222 is adjusted to the desired length, the operator observes the multiple slots 33 on the second rod 222 and selects one that corresponds to the current position. Due to the tension of the spring, when the operator aligns the insertion rod 32 with the selected slot 33, the spring automatically pulls the insertion rod 32 toward the second rod body 222, making it easier to insert the insertion rod 32 into the slot 33. Once the insertion rod 32 is inserted into the slot 33, the tension of the spring continues to act on the insertion rod 32, further securing the insertion rod 32 in the slot 33 and enhancing the stability of the fixation. The tension of the spring prevents the insertion rod 32 from accidentally falling out of the slot 33 without external force, ensuring that the length of the support rod 22 is securely locked.

[0044] In order to guide the rod 32, please refer to Figure 3 In a preferred embodiment, the end of the insertion rod 32 close to the second rod body 222 is spherical.

[0045] During use, the spherical end also serves as a guide during the sliding process. When the operator adjusts the position of the second rod 222, the spherical end can more easily roll or slide on the surface of the second rod 222, helping the operator to more accurately align the insertion rod 32 with the slot 33 at different positions.

[0046] In order to reduce the possibility of damage to the inner and outer limiting belts 11 and 12, please refer to Figure 3 In a preferred embodiment, the inner limiting belt 11 and the outer limiting belt 12 are both provided with a wear-resistant layer on their adjacent sides.

[0047] During use, when the medicine bottle moves on the conveyor belt, the side of the medicine bottle will contact the inner limiting belt 11 and the outer limiting belt 12. Since the medicine bottle may produce a certain amount of shaking and friction during the transportation process, the limiting belt will be subjected to friction from the medicine bottle. The wear-resistant layer is made of wear-resistant material with high hardness and wear resistance. When the medicine bottle contacts the limiting belt and friction occurs, the wear-resistant layer can withstand most of the friction, thereby reducing the wear of the main material of the inner limiting belt 11 and the outer limiting belt 12. This extends the service life of the limiting belt and reduces the frequency and cost of replacing the limiting belt.

[0048] In order to better understand this application, the following Figure 1 - Figure 3 The working principle of a device for adjusting the width of a medicine bottle conveyor belt, as a technical solution of this application, is described in detail: an inner limiting belt 11 is fixedly attached to the inside of a corner of the conveyor frame. Its function is to provide an inner boundary for the medicine bottles on the conveyor belt, preventing them from excessively shifting inward during conveyance. An outer limiting belt 12 is disposed on the outside of the corner of the conveyor frame, with both ends fixedly attached to the conveyor frame. The outer limiting belt 12 cooperates with the inner limiting belt 11 to provide an outer boundary for the medicine bottles, ensuring that the bottles remain within a certain width range during conveyance. An adjustment mechanism 2 is disposed on the conveyor frame and can adjust the curvature of the outer limiting belt 12. As the adjustment mechanism 2 adjusts the curvature of the outer limiting belt 12, the distance between the outer limiting belt 12 and the inner limiting belt 11 changes. Increasing the curvature of the outer limiting belt 12 causes it to bend outward, increasing the distance; conversely, decreasing the curvature of the outer limiting belt 12 decreases the distance. This medicine bottle conveyor belt width adjustment device realizes flexible adjustment of the width of the medicine bottle turning belt conveyor through the cooperation of the limiting mechanism 1 and the adjustment mechanism 2, adapts to different medicine bottle sizes, prevents medicine bottle deviation, improves conveying accuracy, is convenient and quick to operate, and provides reliable guarantee for the transportation and production of medicine bottles.

[0049] The specific implementation methods of the present application described above do not limit the scope of protection of the present application. Any other corresponding changes and modifications made based on the technical concept of the present application should be included in the scope of protection of the claims of the present application.
