Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and in particular to a capsule polishing machine for pharmaceutical production. Background Technology

[0002] In the pharmaceutical manufacturing process, the smoothness of the capsule surface directly affects the product's appearance quality and market acceptance. Therefore, capsule polishing is a crucial step in pharmaceutical packaging, aiming to remove dust and impurities adhering to the capsule surface and improve its smoothness and cleanliness to meet the high-quality standards required for pharmaceutical production. Traditional equipment often uses a single-direction polishing method, which has certain limitations. Traditional capsule polishing equipment generally uses a single-direction polishing method, which makes it difficult to achieve all-round, dead-angle-free polishing of capsules in the polishing chamber. This can easily lead to insufficient uniformity of capsule surface polishing, local wear, or polishing omissions, affecting the overall quality of the product.

[0003] Therefore, in view of the defects of the above-mentioned traditional capsule polishing equipment, a capsule polishing machine for pharmaceutical production can be designed. By designing a bidirectional rotating structure of the outer polishing mechanism and the inner polishing mechanism, the friction force generated by the reverse rotation can be used to improve the polishing uniformity, thereby facilitating the solution of the above problems.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] Example: Figures 1-6 As shown, a capsule polishing machine for pharmaceutical production includes an outer cylinder 1, an outer polishing mechanism 2, an inner polishing mechanism 3, a spiral distributing cylinder 4, an empty capsule suction mechanism 5, and a receiving tray 6. The outer cylinder 1 has a centrifugal feeding hopper 101 inside, and a receiving platform 102 is located at the bottom center of the centrifugal feeding hopper 101. Above the receiving platform 102 is an outer polishing mechanism 2 for forward polishing of capsules. The outer polishing mechanism 2 includes a polishing cylinder 201, and a polishing cavity 202 is located inside the polishing cavity 202. Inside the polishing cavity 202 is an inner polishing mechanism 3 for reverse polishing of capsules. The lower end of the outer cylinder 1 has a spiral distributing cylinder 4 for dispersing capsules. The outer end of the spiral distributing cylinder 4 has an empty capsule suction mechanism 5 for generating negative pressure to suction empty capsules. The lower end of the empty capsule suction mechanism 5 has a receiving tray 6 for collecting the polished capsules.

[0017] The inner wall of the polishing chamber 202 is fitted with a polishing felt 203. Four sets of lifting door slots 204 are arranged around the outer end of the polishing chamber 202. The bottom of the four sets of lifting door slots 204 is provided with a centrifugal discharge port 205 that connects to the polishing chamber 202. Each of the four sets of lifting door slots 204 is provided with an electric lifting door plate 206 corresponding to the centrifugal discharge port 205. The outer wall of the capsule is flexibly polished by the polishing felt 203. The opening and closing of the centrifugal discharge port 205 can be controlled by the lifting door slots 204 and the electric lifting door plate 206 at the outer end of the polishing chamber 202. The centrifugal force is used to realize the rapid and orderly discharge of the capsule, avoid accumulation and blockage, and ensure uniform discharge.

[0018] The support platform 102 has a motor compartment 105 inside, and a first servo motor 207 (model AKM2G-2x) is installed inside the motor compartment 105. The output shaft of the first servo motor 207 passes through the support platform 102 and connects to the polishing cylinder 201. A rotating hole 104 for accommodating the output shaft is opened at the center of the surface of the support platform 102. A sealing plate 106 is matched at the lower end of the motor compartment 105. An external polishing control switch 108 connected to the first servo motor 207 is provided at the outer end of the outer cylinder 1. The edge of the support platform 102... A feeding ramp 103 is provided along the bottom edge of the centrifugal feeding bin 101, and multiple sets of feeding ports 107 are arranged around the bottom edge. By setting a motor chamber 105 and a first servo motor 207 inside the receiving platform 102, power is provided to the external polishing mechanism 2, so that the polishing cylinder 201 can rotate in the forward direction to polish the capsule. A sealing plate 106 is provided to protect the internal structure of the motor chamber 105. An external polishing control switch 108 makes it convenient for operators to control the external polishing mechanism 2. The feeding ramp 103 and multiple sets of feeding ports 107 help the capsule fall smoothly from the centrifugal feeding bin 101.

[0019] The inner polishing mechanism 3 includes a cover plate 301. A rotating shaft 302 is located at the center of the lower end of the cover plate 301. The lower end of the rotating shaft 302 extends into the interior of the polishing chamber 202. Multiple sets of movable sleeve shafts 303 are arranged around the outer end of the rotating shaft 302. Brush rollers 304 are fitted onto the outer ends of the multiple sets of movable sleeve shafts 303. A second servo motor 305 (model MHMF042L1U2M) is located at the center of the upper end of the cover plate 301 and is connected to the rotating shaft 302. A handle 306 connected to the cover plate 301 is located above the second servo motor 305. An inner polishing switch 307 is provided on the surface of the handle 306. The rotating shaft 302, movable sleeve shafts 303, and brush rollers 304 located at the lower end of the cover plate 301, in conjunction with the second servo motor 305, enable the inner polishing mechanism 3 to rotate in the opposite direction, thereby improving the polishing uniformity in conjunction with the outer polishing mechanism 2. The handle 306 and the inner polishing switch 307 facilitate the operation of the inner polishing mechanism 3 by the operator, improving the ease of operation of the equipment.

[0020] The spiral dispensing cylinder 4 has a dispensing chamber 401 inside, and a screw separation track 402 inside the dispensing chamber 401. Multiple sets of negative pressure suction ports 403 are opened through the side wall of the dispensing chamber 401 from top to bottom along the screw separation track 402. The outer wall of the dispensing cylinder has two sets of buckles 404, which are located on both sides of the negative pressure suction ports 403. The capsules can be dispersed through the dispensing chamber 401 and the screw separation track 402, so that the capsules can be better separated and transported after polishing. The multiple sets of negative pressure suction ports 403 provide suction positions for the empty shell suction mechanism 5, which facilitates the suction of empty shell capsules. The two sets of buckles 404 provide a fixed position for the installation of the empty shell suction mechanism 5.

[0021] The empty capsule suction mechanism 5 includes a suction hood 501. The front end of the suction hood 501 is covered with multiple sets of negative pressure suction ports 403. Both sides of the suction hood 501 are provided with corresponding clips 502 for buckles 404. The rear end of the suction hood 501 is provided with a suction bucket 503, a suction pipe 504 and a fan 508 in sequence. By covering the negative pressure suction ports 403 with the suction hood 501, empty capsules can be accurately suctioned. The clips 502 cooperate with the buckles 404 to facilitate the installation and removal of the suction hood 501. The suction bucket 503, suction pipe 504 and fan 508 form a suction system to realize the suction function of empty capsules.

[0022] The middle section of the suction pipe 504 is equipped with a filter screen 507, and the bottom of the front section of the suction pipe 504 is provided with a collection port 505 adjacent to the filter screen 507. A collection tank 506 is provided below the collection port 505. The air being sucked in can be filtered through the filter screen 507 to prevent empty capsules from entering the blower 508 and to protect the blower 508 equipment. The collection port 505 and the collection tank 506 facilitate the collection of empty capsules that are intercepted by the filter screen 507.

[0023] During operation, the cover plate 301 of the inner polishing mechanism 3 is first lifted by the handle 306, and the capsule to be polished is poured into the polishing chamber 202. Then the cover plate 301 is closed. At this time, the polishing soft felt 203 on the inner wall of the polishing chamber 202 and the brush roller 304 form an annular polishing space. Then the outer polishing control switch 108 and the inner polishing switch 307 are turned on. The first servo motor 207 drives the polishing cylinder 201 to rotate in the forward direction. The polishing soft felt 203 on its inner wall performs flexible polishing on the outer wall of the capsule. The second servo motor 305 drives the brush roller 304 to rotate in the reverse direction through the rotating shaft 302. The bristles penetrate into the gap between the capsules to sweep away the dust. The capsules make irregular rolling movements under the action of bidirectional friction, realizing all-round surface cleaning.

[0024] After polishing, the electric lifting door 206 is raised to open the centrifugal discharge port 205. Under the centrifugal force generated by the rotation of the polishing cylinder 201, the capsules are evenly dispersed from the discharge port 107 to the distribution bin 401 of the spiral distribution cylinder 4 through the centrifugal discharge port 205 and the discharge slope 103. The capsules are gradually dispersed as they fall along the screw separation track 402.

[0025] When the blower 508 starts, a negative pressure environment is formed inside the suction hood 501. Under the action of negative pressure, the empty capsules are sucked into the suction hood 501 through the negative pressure suction port 403, and then pass through the suction bucket 503 and the suction pipe 504 in sequence. The filter screen 507 set in the middle section of the suction pipe 504 can filter the suction air and prevent the empty capsules from entering the blower 508, thus protecting the blower 508 equipment. The empty capsules intercepted by the filter screen 507 fall into the collection tank 506 through the collection port 505 opened at the bottom of the front section of the suction pipe 504, thus collecting the empty capsules. The capsules that are not sucked up fall into the collection tray for collection.

[0026] Its working principle is as follows: This equipment forms a bidirectional rotating structure by setting an outer polishing mechanism 2 and an inner polishing mechanism 3. The outer polishing mechanism 2 is driven by a first servo motor 207 to rotate the polishing cylinder 201 in the forward direction for polishing. The inner polishing mechanism 3 is driven by a second servo motor 305 to drive the rotating shaft 302. The rotating shaft 302 drives the movable sleeve shaft 303 and the brush roller 304 to rotate in the opposite direction for polishing. The friction generated by this bidirectional rotation enables the capsules to be polished in all directions without dead angles in the polishing chamber 202. The centrifugal feeding hopper 101 uses a combination of gravity and centrifugal force to make the capsules enter the polishing chamber 202 in an orderly manner. The screw separation track 402 of the spiral dispensing cylinder 4 disperses the capsules one by one through the spiral structure. Based on the weight difference between empty capsules and qualified capsules, the empty capsule suction mechanism 5 accurately adsorbs empty capsules through negative pressure, while qualified capsules continue to fall due to their greater weight, realizing automated screening. Its beneficial effects are significant. This application utilizes the bidirectional rotating structure of the outer polishing mechanism 2 and the inner polishing mechanism 3, and the friction generated by the reverse rotation, to enable the capsules to be polished in all directions and uniformly within the polishing chamber 202, effectively improving the smoothness and cleanliness of the capsules and meeting the high-quality standards required for pharmaceutical production. The design of the spiral dispensing cylinder 4 can disperse the capsules, allowing them to be better separated and transported after polishing, avoiding capsule accumulation and blockage, and ensuring the continuous and stable operation of the equipment. The empty capsule suction mechanism 5 accurately suctions empty capsules through the negative pressure suction port 403. The design of the filter screen 507 and the collection tank 506 prevents empty capsules from entering the blower 508, protecting the equipment and facilitating cleaning, thereby improving the accuracy and efficiency of empty capsule separation.
