Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production equipment technology, and in particular to a conveyor belt for filling pharmaceutical glass bottles. Background Technology

[0002] A conveyor belt is a material handling machine that continuously transports materials along a certain route. It is also known as a continuous conveyor. Its working principle is that when the motor drives the conveyor belt wheel to rotate, the friction between the wheel and the belt causes the belt surface to move, thereby moving the material placed on it forward. In the process of filling pharmaceutical glass bottles, it is necessary to use a conveyor belt to accurately transport the glass bottles to the bottom of the filling head to ensure the accuracy of filling.

[0003] Due to factors such as wear and tear of mechanical parts and fluctuations in motor speed, the conveyor belt speed may be unstable, resulting in inaccurate filling of glass bottles. Sudden changes in speed may also cause the glass bottles to shake or collide, increasing the risk of glass bottle breakage. In view of the above reasons, this application proposes a conveyor belt for filling pharmaceutical glass bottles. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a conveyor belt for filling pharmaceutical glass bottles.

[0005] The technical solution of this utility model is as follows: a conveyor belt for filling pharmaceutical glass bottles, including a frame for installation, a plurality of conveying rollers are provided inside the frame, a conveyor belt for conveying is sleeved on the outside of the plurality of conveying rollers, and a buffer zone for monitoring the number of medicine bottles is provided above the frame.

[0006] The buffer zone includes a mounting bracket for fixing, with multiple ultrasonic transmitters and ultrasonic receivers on the inner wall of the mounting bracket. A programmable logic controller for comparison control is provided on the front of the mounting bracket. A buzzer for alarm and a mounting box for installation are provided on the top of the mounting bracket. An electric push rod for driving is provided inside the mounting box.

[0007] Optionally, a drive motor is fixedly provided on the front of the frame, the output end of the drive motor is fixedly connected to one end of one of the conveying rollers, and four support legs arranged in a rectangular pattern are fixedly provided on the bottom of the frame.

[0008] Optionally, a rotating shaft is movably provided inside the mounting box, a gear is fixedly provided on the rotating shaft, and a toothed plate is fixedly provided at the output end of the electric push rod, with the toothed plate and the gear meshing and transmitting power.

[0009] Optionally, a mounting plate one is fixedly provided on the rotating shaft, and a mounting plate two is fixedly provided on the inner wall of the back of the mounting box. A conductive block is provided on the side of the mounting plate one and the mounting plate two that are close to each other.

[0010] Optionally, the inner walls on both sides of the mounting box are provided with round holes, and bearings are fixedly installed in both round holes. The inner rings of the two bearings are fixedly sleeved on the rotating shaft.

[0011] Optionally, a support and shock absorption structure is fixedly provided inside the frame. The support and shock absorption structure includes a base plate for fixing. Multiple dampers are fixedly provided on the top of the base plate. The output ends of the multiple dampers are fixedly provided on the same top plate. Multiple guide rollers are movably provided on the top of the top plate.

[0012] Optionally, a spring is fitted onto the damper, with the top and bottom of the spring respectively fitting against the top plate and the bottom plate. The top of the top plate is provided with multiple mounting grooves, and the guide roller is movably connected to the mounting grooves.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1. This utility model, through the setting of an ultrasonic transmitter, an ultrasonic receiver and a programmable logic controller, allows the buffer to monitor the number of bottles inside and compare the real-time monitored number of bottles with a preset value. When the value differs, the programmable logic controller can control the speed and position of the conveyor belt by controlling the speed of the drive motor and the pause time, so as to ensure the accuracy of the filling quantity.

[0015] 2. By using dampers, springs, and guide rollers, this utility model allows the conveyor belt to transmit vibrations to multiple guide rollers when the equipment vibrates during transportation. The guide rollers then drive the top plate, which in turn compresses the springs and dampers. The springs and dampers effectively absorb the vibrations during the conveyor belt's operation, reducing the shaking and collision of glass bottles caused by vibrations and lowering the risk of glass bottle breakage.

[0032] Example 1

[0033] like Figure 1-3 As shown, the present invention proposes a conveyor belt for filling pharmaceutical glass bottles, including a frame 1 for installation, a plurality of conveying rollers 2 inside the frame 1, a conveyor belt 3 for conveying is sleeved on the outside of the plurality of conveying rollers 2, a drive motor 4 is fixedly installed on the front of the frame 1, the output end of the drive motor 4 is fixedly connected to one end of one of the conveying rollers 2, four support legs arranged in a rectangle are fixedly installed at the bottom of the frame 1, and a buffer zone 5 for monitoring the number of medicine bottles is provided above the frame 1.

[0034] The buffer zone 5 includes a mounting bracket 501 for fixing the equipment. Multiple ultrasonic transmitters 502 and ultrasonic receivers 503 are mounted on the inner wall of the mounting bracket 501. A programmable logic controller 504 for comparison control is located on the front of the mounting bracket 501. A buzzer 512 for alarm and a mounting box 505 for installation are located on the top of the mounting bracket 501. The buzzer 512 can sound an alarm if the number of bottles in the buffer zone 5 does not match a preset value, alerting relevant personnel to the equipment conveying abnormality and allowing them to take timely countermeasures. An electric actuator is located inside the mounting box 505 for driving the equipment. 506. A rotating shaft 508 is movably installed inside the mounting box 505. Circular holes are provided on both inner walls of the mounting box 505, and bearings are fixedly installed in both circular holes. The inner rings of the two bearings are fixedly sleeved on the rotating shaft 508. Mounting plate 1 510 is fixedly installed on the rotating shaft 508. Mounting plate 2 511 is fixedly installed on the inner wall of the back of the mounting box 505. Conductive blocks are provided on the side of mounting plate 1 510 and mounting plate 2 511 that are close to each other. Gear 509 is fixedly installed on the rotating shaft 508. A toothed plate 507 is fixedly installed at the output end of the electric push rod 506. The toothed plate 507 and gear 509 mesh and drive each other.

[0035] In this embodiment, the drive motor 4 is a servo motor. The positive terminal of the buzzer 512 and the conductive block on the mounting plate 511 are connected by a wire. The conductive block on the mounting plate 511 and the positive terminal of the power supply component are also connected by a wire. When the equipment is running, the medicine bottles move on the conveyor belt 3 and enter the buffer zone 5. When the bottles pass through, they block the propagation of ultrasonic waves, causing a change in the ultrasonic signal received by the ultrasonic receiver 503. This allows for the monitoring and counting of the bottles, and the data is transmitted to the programmable logic controller 504. When the number of bottles in the buffer zone 5 differs from the preset value, the programmable logic controller 504 will adjust the monitoring data based on the buffer zone 5. The number of bottles received controls the speed and pause duration of the drive motor 4, thereby adjusting the conveying speed and position of the conveyor belt 3 to ensure the accuracy of the filling volume. When the number of bottles in the buffer zone 5 does not match the set value, the electric push rod 506 is activated. The electric push rod 506 then drives the toothed plate 507, which in turn drives the gear 509. The gear 509 then drives the rotating shaft 508, which in turn drives the mounting plate 1 510. When the conductive block on the mounting plate 1 510 and the conductive block on the mounting plate 2 511 come into contact, the buzzer 512 is energized to sound an alarm, which can remind relevant personnel of the abnormal equipment conveying and allow them to take corresponding measures in a timely manner.

[0036] Example 2

[0037] like Figure 1-4 As shown, based on Embodiment 1, a support and shock-absorbing structure 6 is fixedly installed inside the frame 1. The support and shock-absorbing structure 6 includes a base plate 601 for fixing, a plurality of dampers 602 are fixedly installed on the top of the base plate 601, and the output ends of the plurality of dampers 602 are fixedly installed on the same top plate 603. A spring 604 is sleeved on the damper 602, and the top and bottom of the spring 604 are respectively in contact with the top plate 603 and the base plate 601. A plurality of guide rollers 606 are movably installed on the top of the top plate 603. The arrangement of the guide rollers 606 can reduce the impact with the conveyor. The friction between belts 3 is reduced. The top plate 603 is provided with multiple mounting grooves 605. The guide rollers 606 are movably connected to the mounting grooves 605. When the equipment vibrates during transportation, the conveyor belt 3 will transmit the vibration to the multiple guide rollers 606. The guide rollers 606 then drive the top plate 603. The top plate 603 then compresses the spring 604 and the damper 602. The spring 604 and the damper 602 can effectively absorb the vibration during the operation of the conveyor belt 3, reduce the shaking and collision of glass bottles caused by vibration, and reduce the risk of glass bottle breakage.

[0038] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
