Description

Technical Field

[0001] The invention relates to the technical field of tablet packaging equipment, in particular to tablet production and packaging equipment. Background Art

[0002] In order to enable convenient and accurate drug administration and improve drug stability and efficacy, drug ingredients and excipients are usually mixed, granulated, and compressed to form tablets for oral administration. The currently commonly used quantitative packaging equipment for tablet production is a blister machine. The blister machine usually heats the packaging material through a heating molding component and then forms a blister plate through negative pressure. After that, the tablets are placed in the blister plate, and the blister plate containing the tablets is packaged using packaging materials through a heat sealing component, thereby realizing the quantitative packaging operation of tablet production.

[0003] When the existing tablet production quantitative packaging equipment is used, a sweeping device equipped with a brush head is usually used to brush the tablets into the blister plate by continuous brushing. When this sweeping device is used, since the size of the blisters on the blister plate is close to the size of the tablets, it is not easy for the tablets to fall into the blisters, which easily causes the blister to be empty. Once the blister is empty, it is usually necessary to pause and replenish the material manually, thereby reducing production efficiency. At the same time, in the process of continuous brushing of the brush head, the tablets will inevitably collide with each other and produce broken particles. The existing tablet production quantitative packaging equipment cannot remove the broken particles, and the broken particles enter the blisters, making the tablets in the blisters non-compliant, affecting the accuracy of the tablet dosage.

[0013] Compared with the prior art, the present invention has the following beneficial effects: the loading box holds the tablets to be packaged, the tablets enter the feeding conduit and are arranged under the action of gravity, the tablets contact each other, and the tablets in the feeding tube are avoided to be empty, the driving unit drives the suction unit to place the tablets in the feeding conduit on the machine table, and the empty package is avoided, the loading box and the feeding conduit can screen out the broken particles, and avoid the broken particles from entering the blister, thereby improving the accuracy of the tablet dosage, specifically:

[0014] 1. When the driving slide groove slidably arranged on the matching plate performs reciprocating sliding, since the driving slide groove is arranged obliquely, the driving slide groove can drive the driving slide column slidably connected thereto to slide along the matching slide groove. At the same time, the guide slide column slides along the supporting slide groove. Since both the matching slide groove and the supporting slide groove are L-shaped structures, and under the action of the steering groove, the suction bracket performs reciprocating movements of taking, turning and discharging materials. The suction bracket can synchronously take the tablets in the unloading conduits on both sides, thereby improving the efficiency of tablet packaging;

[0015] 2. When the driving slide is reciprocating, the driving arm drives the vibration plate to move through the driving rod. Under the cooperation of the positioning slide bar, the vibration plate drives the moving plate to reciprocate up and down through the guide slide plate and the connecting bracket. The moving plate drives the sieving grid connected to the loading box to rotate by rotating the connected sliding guide plate, thereby sieving the tablets. The broken materials enter the collecting bin through the sieving grid under the action of gravity, thereby preventing the broken materials from entering the feeding conduit and the blister, thereby improving the accuracy of the tablet dosage in the blister;

[0016] 3. When the suction bracket moves toward the direction of the discharge pipe, the suction bracket drives the limit slide to move upward through the wedge block, so that the suction unit can take the tablets through negative pressure. On the contrary, when the suction unit moves away from the discharge pipe, the limit spring and the gravity of the limit slide work together to drive the limit slide to reset, block the tablets, prevent the tablets from falling off from the discharge pipe, and improve the protection of the tablets.

[0017] 4. The suction slide column cooperates with the suction spring. When the vacuum generator drives the suction plate to contact the tablet, it avoids excessive pressure on the tablet by the suction plate, prevents damage to the tablet, causes the tablet to break, prevents the blister from having empty packs, and avoids the appearance of broken particles in the blister, thereby improving the accuracy of the tablet dosage in the blister.

DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0032] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 With attached Fig.11As shown, a tablet production and packaging equipment includes a machine platform 1, on which a heat sealing unit 2 is provided, on which a loading component 3 for holding tablets is provided, on which a unloading component 4 connected to the loading component 3 is symmetrically provided on the machine platform 1, the unloading component 4 includes a unloading conduit 41, the loading component 3 includes a loading bottom plate 31, on which a loading box 32 connected to the unloading conduit 41 is provided, on which a packaging component 5 is provided for cooperating with the unloading conduit 41 to transfer tablets to the machine platform 1, on which a suction unit 53 for adsorbing tablets by negative pressure and a driving unit 54 for driving the suction unit 53 are provided.

[0033] The machine 1 is internally equipped with a packaging film supply system, a heating system, a negative pressure molding system and a conveying system. The packaging film supply system heats and softens the packaging film through the heating system and then enters the negative pressure molding system to form a blister matching the tablet through the negative pressure of the softened packaging film. The conveying system provides power for the movement of the packaging film. This is the current existing technology and will not be described in detail here.

[0034] The working principle of the present invention is as follows: the machine 1 processes the packaging film into blisters and then conveys them to the top of the machine 1 to wait for tablets to be filled. The loading box 32 contains tablets to be packaged. Under the action of gravity, the tablets enter the discharge conduit 41. The driving unit 54 drives the suction unit 53 to take out the tablets in the discharge conduit 41 and put them into the blisters. After that, the blisters filled with tablets are moved to the heat sealing unit 2 for heat sealing, thereby realizing the quantitative packaging operation of the tablets.

[0035] Combined with Figure 4 , Attachment Figure 5 , Attachment Figure 6 With attached Figure 7 As shown, the subassembly assembly 5 includes a support plate 51 arranged at the lower end of the loading bottom plate 31, and the support plate 51 is symmetrically provided with a support slide 511, and a suction unit 53 is slidably connected to the support slide 511. The support plate 51 is provided with a matching plate 52, and the matching plate 52 is provided with a matching slide 521 slidably connected to the suction unit 53. The suction unit 53 includes a suction bracket 531, and one side of the suction bracket 531 is provided with a guide slide column 532 slidably connected to the support slide 511. The suction bracket 531 is provided with a guide slide column 532 slidably connected to the support slide 511. A driving slide column 533 is provided on one side and is slidably connected to the matching slide groove 521. Both the support slide groove 511 and the matching slide groove 521 are L-shaped structures. A steering groove 512 that cooperates with the guide slide column 532 is provided at the corner of the support slide groove 511. A driving unit 54 that drives the driving slide column 533 to slide along the matching slide groove 521 is provided on the matching plate 52. The driving unit 54 includes a driving slide groove 542 that is slidably set on the matching plate 52 and is slidably connected to the driving slide column 533, and the driving slide groove 542 is inclined.

[0036] The working principle of the packaging component 5 is as follows: when the driving slide 542 slides upward, since the driving slide 542 is inclined, the driving slide 542 drives the driving slide column 533 connected thereto to slide along the matching slide 521, and the driving slide column 533 drives the guide slide column 532 to slide synchronously along the supporting slide 511 through the suction bracket 531. At this time, the suction unit 53 faces the direction of the machine 1. When the guide slide column 532 moves to the steering groove 512, the driving slide 542 continues to move upward. At this time, the driving slide column 533 drives the suction bracket 531 to turn, and the suction bracket 531 faces the direction of the discharge pipe 41. The driving slide 542 continues to move upward, and the driving slide column 533 drives the suction bracket 531 to slide in the direction of the discharge pipe 41, so that the tablets can be taken with the cooperation of the suction unit 53;

[0037] When the driving slide groove 542 slides downward, the driving slide groove 542 drives the driving slide column 533 connected thereto to slide along the matching slide groove 521, and the driving slide column 533 drives the guide slide column 532 to slide synchronously along the supporting slide groove 511 through the suction bracket 531. At this time, the suction unit 53 moves away from the discharge pipe 41. When the guide slide column 532 moves to the steering groove 512, the driving slide groove 542 continues to move downward. At this time, the driving slide column 533 drives the suction bracket 531 to turn, and the suction bracket 531 moves toward the machine 1. The driving slide groove 542 continues to move downward, and the driving slide column 533 drives the suction bracket 531 to slide toward the machine 1. Then, the tablet can be placed in the blister with the cooperation of the suction unit 53, and this is repeated. The up and down reciprocating motion of the driving slide groove 542 can drive the suction unit 53 to take and place the tablets in the discharge pipe 41, and the working efficiency is high.

[0038] Combined with Figure 5 With attached Figure 6 As shown, the mating plate 52 is provided with a positioning groove 522, and a driving slider 541 is slidably provided in the positioning groove 522. The driving slider 541 is connected to the driving groove 542. A driving screw 543 is rotatably provided on the mating plate 52. The driving screw 543 cooperates with the driving groove 542 through a thread. The driving screw 543 can be driven by a motor to rotate back and forth, and can also be driven by the motor to drive the reciprocating screw to rotate unidirectionally. A reciprocating thread is set on the driving screw 543 to drive the driving groove 542 to reciprocate.

[0039] Combined with Figure 3 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 With attached Fig.10As shown, the loading box 32 is provided with a positioning slide bar 311, a guide slide plate 312 is slidably provided on the positioning slide bar 311, a connecting bracket 33 is provided on the guide slide plate 312, a movable plate 34 is provided at one end of the connecting bracket 33 extending into the loading box 32, a sliding guide plate 35 is rotatably provided on the movable plate 34, a screening grille 36 slidably connected to the sliding guide plate 35 is rotatably provided on the loading box 32, a collecting bin 39 is provided under the screening grille 36 of the loading box 32, and a collecting drawer 33 cooperating with the collecting bin 39 is slidably provided on the loading box 32 91, a driving arm 544 is provided on the driving slide 542, a driving rod 545 is provided on the driving arm 544, a vibration plate 313 cooperating with the driving rod 545 is provided on the guide slide 312, a moving sleeve 341 connected to the moving plate 34 is slidably provided on the loading box 32, an L-shaped bracket 342 is provided on the loading box 32, a moving slide rod 3421 slidably connected to the moving sleeve 341 is provided on the L-shaped bracket 342, and a lateral spring 343 sleeved on the moving slide rod 3421 is provided on the moving sleeve 341.

[0040] The working principle of the screening grid 36: in the process of driving the slide 542 to reciprocate up and down, the driving slide 542 drives the driving rod 545 to reciprocate up and down through the driving support arm 544 connected thereto. When the driving rod 545 moves upward, the driving rod 545 drives the guide slide 312 to slide upward along the positioning slide 311 through the vibration plate 313, and the guide slide 312 drives the moving plate 34 to move upward synchronously through the connecting bracket 33. At this time, the moving plate 34 drives the sliding guide plate 35 to rotate, and the sliding guide plate 35 drives the screening grid 36 to rotate, and the screening grid 36 drives the tablets to move toward the direction close to the discharge pipe 41, and the screening grid 36 screens the tablets, and the broken particles are Under the action of gravity, the tablets are temporarily placed in the collection drawer 391 arranged in the collection bin 39. During this process, the sliding guide plate 35 and the screening grid 36 slide relative to each other. At the same time, the moving sleeve 341 slides along the moving slide rod 3421, and the moving sleeve 341 squeezes the lateral spring 343, and the lateral spring 343 contracts under the force. On the contrary, when the driving rod 545 moves downward, the lateral spring 343 is reset, and the lateral spring 343 drives the moving plate 34 to move downward through the moving sleeve 341, and the screening grid 36 rotates synchronously, thereby realizing the screening of the tablets. Therefore, in the process of driving the slide groove 542 to reciprocate up and down, the tablets are screened to prevent broken particles from entering the blister.

[0041] Combined with Figure 8 , Attachment Fig. 9 With attached Fig.10As shown, the loading box 32 is provided with a discharge hole 38 connected to the discharge conduit 41, and a brush guide roller 37 cooperating with the discharge hole 38 is rotatably provided in the loading box 32. A tablet brush 371 is provided on the brush guide roller 37. The brush guide roller 37 can be driven by a motor, and the brush guide roller 37 drives the tablet brush 371 to rotate to avoid tablets from piling up in the discharge hole 38, improve the smoothness of tablet movement, and avoid tablet gaps in the discharge conduit 41.

[0042] Combined with Figure 3 , Attachment Figure 4 , Attachment Fig. 9 , Attachment Fig.11 With attached Fig.12 As shown, the material discharge conduit 41 is provided with multiple groups of material plates 42 at equal intervals, and the multiple groups of partition plates divide the material discharge conduit 41 into material discharge channels that match the tablets. The material discharge conduit 41 is an L-shaped structure, and the lower end of the material discharge conduit 41 is provided with an opening, and the lower end of the material discharge conduit 41 is provided with a material discharge grid 43. The lower end of the material discharge conduit 41 is connected to a material discharge bin 431 through the material discharge grid 43, and a material collection drawer 44 is slidably provided in the material discharge bin 431. A positioning plate 411 is provided on the material discharge conduit 41, and a limit spring 414 is provided at the lower end of the positioning plate 411. A limit slot 412 is provided on the limit slot 412, and a limit slide plate 413 connected to a limit spring 414 is slidably provided on the limit slot 412. A wedge block 415 is provided on the limit slide plate 413 for cooperating with the suction unit 53 to drive the limit slide plate 413 to slide back and forth along the limit slot 412. The suction unit 53 includes a suction plate 534 arranged on the suction bracket 531, and a driving block 538 is provided on the suction plate 534. The driving block 538 is an L-shaped structure, and a driving column 5381 is provided on the driving block 538 for slidingly abutting against the wedge block 415.

[0043] Working principle of the feeding conduit 41: After the tablets enter the feeding conduit 41, they move downward to the feeding grid 43 under the action of gravity. At this time, if there are broken particles, the broken particles will pass through the feeding grid 43 and enter the collecting drawer 44 set in the feeding bin 431 for temporary storage, thereby realizing secondary screening of the broken particles.

[0044] When the suction unit 53 moves toward the discharge conduit 41, the suction bracket 531 drives the suction plate 534 to move synchronously, and the suction plate 534 drives the driving column 5381 to move synchronously through the driving block 538, and the driving block 538 drives the wedge block 415 to move upward, and the limiting slide 413 moves upward synchronously, so as to facilitate the suction unit 53 to take the tablets through negative pressure. On the contrary, when the suction unit 53 moves away from the discharge conduit 41, under the combined action of the limiting spring 414 and the gravity of the limiting slide 413, the limiting slide 413 is reset to block the tablets, thereby preventing the tablets from falling off from the discharge conduit 41 and improving the protection capability of the tablets.

[0045] Combined with Figure 6 With attached Figure 7 As shown, a suction slide 535 is slidably provided on the suction plate 534, and a vacuum generator 537 is provided on the suction slide 535. The vacuum generator 537 is connected to a suction disc 5371, and the suction disc 5371 is arranged corresponding to the discharge conduit 41. A valve and corresponding components are provided between the vacuum generator 537 and the suction disc 5371, so as to control the generation, maintenance and elimination of the negative pressure at the mouth of the suction disc 5371. This is the current prior art. The vacuum generator 537 is provided with a suction spring 536 which is sleeved on the suction slide 535 and connected to the suction plate 534.

[0046] The working principle of the suction disc 5371 is as follows: the suction bracket 531 drives the suction plate 534 to move, and the suction plate 534 drives the vacuum generator 537 to move towards the tablet through the suction slide column 535 and the suction spring 536. The suction disc 5371 contacts the tablet and adsorbs the tablet through the vacuum generator 537, thereby realizing the tablet removal. The setting of the suction spring 536 avoids damage to the tablet due to excessive pressure on the tablet. Furthermore, when the suction bracket 531 drives the vacuum generator 537 to move to cooperate with the blister through the suction plate 534, the negative pressure at the mouth of the suction disc 5371 is controlled to be eliminated. At this time, the tablet enters the blister under the action of gravity, thereby realizing the packaging of the tablet.

[0047] The screw 543 is driven to rotate and the suction bracket 531 is driven to move through the driving chute 542. The suction bracket 531 drives the suction disc 5371 to take out the tablets in the feeding duct 41 through negative pressure and place them in the blister. The blister filled with tablets is heat-sealed by the heat-sealing unit 2, thereby realizing the quantitative packaging operation of the tablets. In this process, the driving chute 542 drives the movable plate 34 to reciprocate up and down, and with the cooperation of the guide slide plate 312, drives the screening grid 36 to reciprocate, thereby realizing the screening of the tablets. The screened broken particles are temporarily stored in the collecting drawer 391 to prevent the broken particles from entering the blister, thereby improving the accuracy of the tablet dosage in the blister. After the operation is completed, the collecting drawer 391 can be dumped to improve the convenience of use.
