Description

Technical Field

[0001] The utility model relates to ointment medicine production equipment, in particular to an ointment tube lifting mechanism of an ointment tube filling equipment. Background Art

[0002] An ointment tube is a soft tube used to hold paste-like substances. Its material is generally an aluminum tube, an aluminum-plastic composite tube or a plastic tube (such as polyethylene). Medicinal ointment tubes have good insulation properties, are not easy to break, are clean and hygienic, are easy to use, are soft to the touch, and are easy to deform. They have become the preferred packaging material for cream preparations by pharmaceutical manufacturers. They are used to produce commonly used over-the-counter dermatological topical drugs such as urea cream and zinc oxide ointment. As the demand for such drugs continues to increase, pharmaceutical manufacturers need to continuously improve the production efficiency of drugs, so they need to realize mechanical automation in all aspects of drug production.

[0003] In the production process of ointment drugs, one of the links is to fill the cream-like drugs into empty medicinal ointment tubes, and then perform a compression operation on the tail of the ointment tube to close the tail of the ointment tube, thereby preventing the cream-like drugs from leaking out of the tail of the ointment tube, and completing the production of the ointment drugs.

[0004] To realize the automatic filling operation, it is necessary to use a synchronous belt to Figure 1 The multiple ointment tubes shown are pushed to the rotating station in a horizontal posture, and the ointment tube rotating mechanism of the rotating station rotates the ointment tubes 90° clockwise to an inverted posture, and finally transported to the filling station.

[0005] Since the ointment tubes are long and thin tubes, the ointment tubes are stacked in a multi-layer arrangement in the preparation box. Figure 2 The synchronous belt must sequentially convey the ointment tubes arranged in a single layer to the ointment tube rotating mechanism in order to realize the subsequent automated operation, so the ointment tubes need to be formed into a single-layer queue.

[0006] At present, the method of obtaining a single-layer queue of ointment tubes is to use their own gravity to make multiple ointment tubes output from the lowest point of the preparation box in sequence. However, since the input end height of the synchronous belt is much higher than the lowest point of the preparation box, the ointment tubes in a single-layer queue output from the preparation box cannot reach the synchronous belt, so automated operation cannot be achieved.

[0014] In another embodiment, the ointment tube lifting mechanisms are arranged in pairs; the distance between the two ointment tube lifting mechanisms matches the length of the ointment tube.

[0015] In another embodiment, the blade rotation directions of the receiving dial wheel, the first lifting dial wheel, the second lifting dial wheel, and the pushing dial wheel are consistent with their rotation directions.

[0038] like Figure 3 As shown, the ointment tube lifting mechanism of the ointment tube filling device of the utility model comprises a receiving dial wheel 1, a first lifting dial wheel 2, a second lifting dial wheel 3, and a pushing dial wheel 4 which are distributed from bottom to top, and the outer edges of the receiving dial wheel 1, the first lifting dial wheel 2, the second lifting dial wheel 3, and the pushing dial wheel 4 are uniformly formed with a plurality of blades along the circumferential direction, and grooves are formed between adjacent blades; the depth of the groove matches the diameter of the ointment tube; during the rotation of each dial wheel, the groove with the opening upward can carry the ointment tube 100 to make a circumferential movement, thereby realizing the transportation of the ointment tube 100;

[0039] The left side of the receiving wheel 1 corresponds to the output end of the material preparation box, and the left end of the receiving wheel 1 serves as the input end of the receiving wheel 1; a first arc-shaped guide plate 5 is fixedly arranged above the input end of the receiving wheel 1, and the first arc-shaped guide plate 5 extends along the second quadrant of the receiving wheel 1, and the second quadrant of the receiving wheel 1 serves as the transport area of ​​the receiving wheel 1;

[0040] The highest point of the receiving dial wheel 1 coincides with the lowest point of the first lifting dial wheel 2. The highest point of the receiving dial wheel 1 serves as its delivery position; the lowest point of the first lifting dial wheel 2 serves as its receiving position.

[0041] A second arc-shaped guide plate 6 is fixedly arranged on the right side of the first lifting wheel 2. The second arc-shaped guide plate 6 extends along the first quadrant and the fourth quadrant of the first lifting wheel 2. The first quadrant and the fourth quadrant of the first lifting wheel 2 serve as the conveying area of ​​the first lifting wheel 2.

[0042] The highest point of the first lifting dial wheel 2 coincides with the lowest point of the second lifting dial wheel 3. The highest point of the first lifting dial wheel 2 serves as its delivery position; the lowest point of the second lifting dial wheel 3 serves as its receiving position.

[0043] A third arc-shaped guide plate 7 is fixedly arranged on the left side of the second lifting wheel 3. The third arc-shaped guide plate 7 extends along the second quadrant and the third quadrant of the second lifting wheel 3. The second quadrant and the third quadrant of the second lifting wheel 3 serve as the conveying area of ​​the second lifting wheel 3.

[0044] The highest point of the second lifting dial wheel 3 coincides with the lowest point of the pushing dial wheel 4. The highest point of the second lifting dial wheel 3 serves as its delivery position, corresponding to the input end of the synchronous belt.

[0045] The lowest point of the push dial 4 can provide a rightward thrust to the ointment tube at the delivery position of the second lifting dial 3 during rotation, thereby pushing the ointment tube from the delivery position of the second lifting dial 3 to the input end of the synchronous belt.

[0046] Preferably, the ointment tube lifting mechanism consisting of the receiving dial wheel 1, the first lifting dial wheel 2, the second lifting dial wheel 3, the pushing dial wheel 4, and the first arc-shaped guide plate 5, the second arc-shaped guide plate 6, and the third arc-shaped guide plate 7 is arranged in pairs, such as Figure 4 As shown; the spacing between the two ointment tube lifting mechanisms matches the length of the ointment tube, so that the two receiving wheels 1, the two first lifting wheels 2, the two second lifting wheels 3, and the two pushing wheels 4 can respectively support the two ends of the ointment tube to prevent the ointment tube from falling from the ointment tube lifting mechanism during the lifting process.

[0047] Preferably, the blade rotation directions of the receiving dial wheel 1, the first lifting dial wheel 2, the second lifting dial wheel 3, and the pushing dial wheel 4 are consistent with their rotation directions; Figure 5 As shown, the receiving dial wheel 1 rotates clockwise, and the blade of the receiving dial wheel 1 rotates right;

[0048] If the first lifting wheel 2 rotates counterclockwise, the blade of the receiving wheel 1 rotates leftward;

[0049] If the second lifting wheel 3 rotates clockwise, the blade of the receiving wheel 1 rotates clockwise;

[0050] When the push wheel 4 rotates counterclockwise, the blade of the receiving wheel 1 rotates counterclockwise.

[0051] The working principle of the utility model is as follows:

[0052] like Figure 5 As shown, the external power source drives the receiving dial wheel 1, the first lifting dial wheel 2, the second lifting dial wheel 3 and the pushing dial wheel 4 to rotate synchronously, and makes the receiving dial wheel 1 rotate clockwise, the first lifting dial wheel 2 rotate counterclockwise, the second lifting dial wheel 3 rotate clockwise, and the pushing dial wheel 4 rotate counterclockwise; the first arc guide plate 5, the second arc guide plate 6 and the third arc guide plate 7 are fixed;

[0053] Multiple ointment tubes 100 sequentially enter the left end groove of the receiving dial wheel 1 from the output end of the preparation box, and the first arc-shaped guide plate 5 located above it can prevent the ointment tube 100 from falling from the groove of the receiving dial wheel 1; during the clockwise rotation of the receiving dial wheel 1, the ointment tube 100 is driven to move from the 9 o'clock position of the receiving dial wheel 1 to the 12 o'clock position, thereby achieving a one-time increase in the height of the ointment tube;

[0054] Since the receiving dial wheel 1 and the first lifting dial wheel 2 overlap at this position, the receiving dial wheel 1 transfers the ointment tube 100 from its 12 o'clock position to the 6 o'clock position of the first lifting dial wheel 2; the second arc-shaped guide plate 6 located on the right side thereof can prevent the ointment tube 100 from falling from the groove of the first lifting dial wheel 2; during the counterclockwise rotation of the first lifting dial wheel 2, the first lifting dial wheel 2 drives the ointment tube 100 to move from the 6 o'clock position of the first lifting dial wheel 2 to the 12 o'clock position, thereby realizing a secondary lifting of the ointment tube height;

[0055] Since the first lifting wheel 2 and the second lifting wheel 3 overlap at this position, the first lifting wheel 2 transfers the ointment tube 100 from its 12 o'clock position to the 6 o'clock position of the second lifting wheel 3, and the third arc-shaped guide plate 7 located on the left side thereof can prevent the ointment tube 100 from falling from the groove of the second lifting wheel 3; the second lifting wheel 3 rotates clockwise, and the second lifting wheel 3 drives the ointment tube 100 to move from the 6 o'clock position of the second lifting wheel 3 to the 12 o'clock position, thereby realizing three times of lifting of the ointment tube height;

[0056] Since the second lifting wheel 3 and the pushing wheel 4 overlap at this station, the pushing wheel 4 rotates counterclockwise, and the lowest point of the pushing wheel 4 provides a rightward thrust for the ointment tube 100 at the 12 o'clock station of the second lifting wheel 3, thereby pushing the ointment tube 100 horizontally toward the input end of the synchronous belt.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these changes and modifications.
