Description

Technical Field

[0001] This invention relates to the field of precision control equipment technology, and in particular to a device for precise control of the size of borosilicate pharmaceutical glass tubes. Background Technology

[0002] Borosilicate pharmaceutical glass tubing is a key material in drug packaging, and its dimensional accuracy directly affects the integrity and sealing of the packaging. During drug production, dimensional deviations in the glass tubing can lead to incomplete sealing, exposing the drug to the external environment and causing problems such as drug deterioration and microbial contamination, seriously threatening the safety and stability of the drug. With the continuous development of the pharmaceutical industry and increasingly stringent quality control, the dimensional accuracy standards for borosilicate pharmaceutical glass tubing are constantly being improved. However, current equipment for inspecting the dimensions of glass tubes has many shortcomings. Common inspection equipment relies heavily on manual operation and simple measuring tools, resulting in low efficiency and accuracy easily affected by human factors, making it difficult to meet the demands of large-scale, high-precision production. While automated inspection equipment exists, most can only perform single-dimensional inspection, failing to simultaneously and accurately measure both the inner and outer diameters of the glass tube, leading to overall low inspection accuracy. Furthermore, the data processing and feedback mechanisms of existing equipment are inadequate, failing to promptly and effectively translate inspection results into production adjustments, hindering real-time and precise control of the glass tube production process. Therefore, we propose a precise dimension control device for borosilicate pharmaceutical glass tubes to address these issues. Summary of the Invention

A push rod is fixedly mounted on the top of the lifting plate. A magnet is fixedly mounted on the top of the push rod, and the magnet is located directly below the corresponding connecting hole. A rotating shaft is rotatably mounted on the bottom of the horizontal plate. The rotating shaft is located inside the guide sleeve. An inner diameter detection seat is fixedly mounted on the bottom end of the rotating shaft. An inner diameter detection mechanism I is provided on both sides of the inner diameter detection seat.

[0005] Preferably, the inner diameter detection mechanism includes a movable groove, a detection protrusion, a pressure sensor, and a fixing spring. The movable groove is opened on both sides of the inner diameter detection seat. The detection protrusion is slidably installed in the movable groove.

[0008] Preferably, a control box is fixedly installed on the top of the horizontal plate, a drive motor is fixedly installed on the top of the control box, and the output shaft of the drive motor is fixedly connected to the drive shaft. A transmission mechanism is provided between the drive motor and the rotating shaft.

[0009] Preferably, the transmission mechanism includes a drive pulley, a driven pulley, and a belt. The drive pulley is fixedly mounted on the output shaft of the drive motor, the driven pulley is fixedly mounted on the rotating shaft, and the same belt is worn on both the drive pulley and the driven pulley.

[0010] Preferably, the inner wall of the groove is provided with connecting grooves with open tops at equal intervals, and a clamping mechanism for fixing the glass tube is provided between the positioning seat and the support sleeve.

[0011] Preferably, the clamping mechanism includes a rectangular hole, a trapezoidal seat, and a rubber seat. The rectangular hole is formed on the inner wall of the positioning groove. The trapezoidal seat is slidably installed in the rectangular hole. A rubber seat is fixedly installed on one side of the trapezoidal seat.

[0014] The beneficial effects of this invention are: 1. Place the glass tube into the placement hole so that the bottom of the glass tube is placed in the positioning groove.

The placement disk can drive the glass tube to rotate directly below the inner diameter detection mechanism and the outer diameter detection mechanism. 2. With the cooperation of the drive motor, drive shaft, threaded rod, and lifting plate, the lifting plate moves the second magnet upward through the push rod. The second magnet attracts the first magnet, and the first magnet can push the seat and glass tube upward. The glass tube can enter the guide sleeve. When the positioning seat moves upward, the support sleeve can squeeze the trapezoidal seat so that the trapezoidal seat can move closer to the glass tube. The trapezoidal seat squeezes and fixes the glass tube through the rubber seat. 3. When the glass tube enters the guide sleeve, the outer side of the guide sleeve presses against the second detection protrusion. The second detection protrusion, through a connecting spring, presses against the second pressure sensor. The second pressure sensor can collect pressure data. The inner diameter detection seat can be inserted into the glass tube, and the inner wall of the glass tube can press against the first detection protrusion. The first detection protrusion, through a fixing spring, presses against the first pressure sensor. The first pressure sensor can collect pressure change data. When the inner or outer diameter error of the glass tube is large, the pressure change data is large. When the pressure change data is greater than the set value, the glass tube is judged to be unqualified and an alarm is triggered. 4. Through the cooperation of the drive pulley, belt and driven pulley, the drive motor can drive the rotating shaft to rotate, the rotating shaft can drive the inner detection seat to rotate, and the inner detection seat can drive the detection protrusion one to rotate. When the glass tube moves upward, the detection protrusion one rotates, which can change the collection position and improve the detection accuracy. Attached Figure Description

[0024] In this embodiment, connecting grooves 401 with open tops are evenly spaced on the inner wall of the groove 303.

[0025] The working principle of this invention is as follows: A glass tube 302 is placed into the placement hole 301, so that the bottom of the glass tube 302 is positioned in the positioning groove 305. By activating the stepper motor 205, the stepper motor 205 drives the rotating disk 202, the support sleeve 203, and the placement disk 204 to rotate. The placement disk 204 drives the glass tube 302 to rotate directly below the inner diameter detection mechanism and the outer diameter detection mechanism. By activating the drive motor 502, the drive motor 502 drives the threaded rod 504 to rotate via the drive shaft 503. The threaded rod 504 then... When the lifting plate 601 moves upward, the lifting plate 601 brings the second magnet 604 upward through the push rod 603. The second magnet 604 attracts the first magnet 406. The first magnet 406 can push the seat and the glass tube 302 upward, and the glass tube 302 can enter the guide sleeve 701. When the positioning seat 304 moves upward, the support sleeve 203 can squeeze the trapezoidal seat 403 so that the trapezoidal seat 403 can move closer to the glass tube 302. The trapezoidal seat 403 is used to squeeze and fix the glass tube 302 through the rubber seat 404. When the glass tube 302 enters the guide sleeve 701, the outer side of the guide sleeve 701 presses against the second detection protrusion 803. The second detection protrusion 803, through the connecting spring 805, presses against the second pressure sensor 804. The second pressure sensor 804 can collect pressure data. Meanwhile, the inner diameter detection seat 703 can be inserted into the glass tube 302, and the inner wall of the glass tube 302 can press against the first detection protrusion 705. The first detection protrusion 705, through the fixing spring 707, presses against the first pressure sensor 706. The first pressure sensor 706 can collect pressure change data. When the glass tube 302... When the inner or outer diameter error is large, the pressure change data is also large. When the pressure change data is greater than the set value, the glass tube 302 is judged to be unqualified and an alarm is issued through the alarm 1002. With the cooperation of the drive pulley 901, belt 903 and driven pulley 902, the drive motor 502 can drive the rotating shaft 702 to rotate. The rotating shaft 702 can drive the inner detection seat to rotate. The inner detection seat can drive the detection protrusion 705 to rotate. When the glass tube 302 moves upward, the detection protrusion 705 rotates, which can change the collection position and improve the accuracy of detection.

Specific embodiments have been used to illustrate the principles and implementation methods of the invention.
