Description

Technical Field

[0001] This invention relates to the field of mechanical design, manufacturing and automation technology, specifically to a device for receiving and switching workstations in a hollow capsule production line. Background Technology

[0002] Empty capsules are primarily used to contain solid and liquid medications. Compared to other oral medications, capsules effectively mask the drug's odor, are easier to swallow, and are easier to store, thus their application is widespread. Currently, capsule product quality varies considerably, with about half supplied by semi-automatic or manual workshops of small and medium-sized enterprises. Furthermore, most empty capsule production lines are currently semi-automatic, failing to meet the high efficiency and sterility requirements of relevant companies during production. Additionally, due to the different capsule models, changing models often requires manual replacement of the actuator, resulting in low efficiency. Summary of the Invention

The sliding bearing is installed on the lower sliding bearing seat and positions the center of the support cylinder.

[0006] Preferably, the hollow capsule production line receiving and station conversion device provided in this application, wherein the positioning component consists of a set of suction blocks, and gas is drawn into the cylindrical sleeve inside the clamping cylinder through the air holes on the suction blocks.

[0012] Preferably, the empty capsule production line receiving and station conversion device provided in this application, wherein the outer side of the roller connecting rod is fixed to the clamping plate by bolts, and the inner side is connected to the internal hexagonal hole type cam guide by bolts and pins.

[0013] Preferably, the empty capsule production line receiving and station conversion device provided in this application includes the following steps in its usage:

[0025] Please see Figure 1-2 This invention provides a technical solution: a receiving and workstation conversion device for an empty capsule production line. The device consists of a support component, a sliding component, a positioning component, a connecting component, and a receiving component. The support component consists of a mounting base 1, a servo motor 2, and a support cylinder 6, which are fixed to the production line frame during operation. The mounting base 1 and the servo motor 2 are connected by bolts, and the servo motor 2 and the support cylinder 6 are also connected by bolts. The inner side of the support cylinder 6 is connected to the cam receiving shaft 3 by bolts.

[0026] In this invention, the sliding assembly consists of an upper sliding bearing seat 11, a lower sliding bearing seat 14, and a sliding bearing 13, which enables the rotation of the external support cylinder 6. The sliding bearing 13 is installed on the lower sliding bearing seat 14 and positions the center of the support cylinder 6.

[0027] In this invention, the positioning component consists of a set of suction blocks 7, and the gas is drawn into the cylindrical sleeve inside the clamping cylinder 8 through the air holes on the suction blocks 7.

[0028] In this invention, the connecting assembly consists of a connecting beam 15, a rolling bearing 4, and a cam 16. The rolling bearing 4 is disposed on one side of the connecting beam 15, and the cam 16 is mounted on the connecting beam 15. There is an air outlet gap between the connecting beam 15 and the air intake block 7, which is 2mm-3mm. The profile of the cam 16 is divided into two parts: an open profile from 265 degrees to 270 degrees and a closed profile from 5 degrees to 10 degrees. The cam 16 and the connecting beam 15 are fixed together by bolts.

[0029] In this invention, the receiving assembly consists of a receiving body 5, a clamping cylinder 8, a clamping plate 9, a roller connecting rod 10, and a cam guide 12. The clamping plate 9 slides radially along the groove on the receiving body 5, and the clamping cylinder 8 has a spring plate structure. The outer side of the roller connecting rod 10 is fixed to the clamping plate 9 by bolts, and the inner side is connected to the internal hexagonal hole type cam guide 12 by bolts and pins.

[0030] Working principle: The method of using this invention includes the following steps:

[0031] A. When the device is working, the servo motor 2 drives the support cylinder 6 to rotate, and pauses for 0.5 seconds every 90 degrees of rotation. The clamping plate 9 follows the rotation of the support cylinder 6, which drives the roller connecting rod 10 and the cam guide 12 to slide along the cam profile.

[0032] B. When the cam guide 12 slides to the open profile section, the clamping piece 9 slides inward, the spring plate of the clamping cylinder 8 is released, and the demolded capsule is received into the clamping cylinder 8.

[0033] C. The pipe joint at the end of the through hole of the connecting beam 15 is connected to the air pump pipeline. The gas enters the air pump through the clamping cylinder 8, the air suction block 7, and the through hole of the connecting beam 15, thereby adsorbing the hollow capsule in the clamping cylinder 8 onto the cylindrical sleeve inside the clamping cylinder 8.

[0034] D. When the cam guide 12 slides to the closed profile, the clamping plate 9 slides outward, and the spring plate of the clamping cylinder 8 locks in place. Every time the supporting cylinder 6 rotates 90 degrees, the device completes one station change, and at the same time, it receives the hollow capsule that has been demolded above the device into the device.

[0035] In summary, this invention proposes a station switching device for a hollow capsule production line. A servo motor drives a supporting cylinder to rotate, enabling high-frequency switching between the receiving and cutting stations. The device utilizes a pair of cam mechanisms with identical profiles to cause a spring-loaded clamping cylinder to open and close once, achieving the receiving function of the hollow capsules. The station switching device for the hollow capsule production line has a simple structure and high working efficiency. In actual production, using this device can achieve high-frequency station switching, effectively reducing the number of online operators, reducing labor intensity, improving processing efficiency, and shortening the production cycle.
