Description

Technical Field

[0001] This application relates to the technical field of packaging equipment components, and particularly to a packaging mechanism for lozenges. Background Art

[0002] Lozenges are a common form of solid medicine. Depending on the required disintegration time, lozenges are made into many different shapes and sizes. Since lozenges are usually packaged in plastic and aluminum foil packages, in order to reduce the breakage of lozenges due to shaking in the package, the cavity of the package needs to be adapted to the specifications of the tablets. Therefore, different lozenges need to be packaged on different packaging mechanisms, so the configuration cost of the packaging mechanism is relatively high. Summary of the Invention

[0003] The purpose of this application is to provide a packaging mechanism that can package more specifications of lozenges.

[0004] To achieve the above object, this application provides a packaging mechanism for lozenges: including a configuration frame, on which a pair of parallel guide rail frames are fixedly connected. Each guide rail frame includes an integral straight part and an arc part, and the straight part and the arc part have continuous chutes. Two guide rail frames jointly slidably connect a turntable through the chutes. The upper surface of the turntable is fixedly connected with a replaceable plate through a connecting member. The upper surface of the replaceable plate is provided with a medicine plate groove, and the inner bottom surface of the replaceable plate in the medicine plate groove is provided with a fitting hole. There are several types of replaceable plates, and only the fitting holes are different between different types of replaceable plates. A cylinder is arranged at the bottom of the configuration frame, which is suitable for driving the turntable to slide along the straight part and the arc part. The angle of the turntable relative to the horizontal plane will change during the sliding process. A pressing component is also arranged on the configuration frame, which is suitable for pressing the two parts of the tablet package together to achieve encapsulation.

[0005] As a preference, the outer side of the turntable has a pair of coaxial connecting shafts and a pair of coaxial follower shafts. The axis of the connecting shaft is only parallel to the axis of the follower shaft. The connecting shaft and the follower shaft are both matched with the chute of the guide rail frame to form a sliding pair, restricting the movement freedom of the turntable.

[0006] As a preference, the configuration frame includes a cross beam fixedly connected to both guide rail frames at the same time. The cross beam is rotatably connected with a cylinder. The lower end of the arc part is fixedly connected with a limit frame. The upper end of the limit frame is rotatably connected with a traction frame. The upper end of the traction frame is rotatably connected with the connecting shaft. The movable end of the cylinder is rotatably connected with the traction frame for power transmission.

[0007] As a preference, the position-limiting frame includes cantilevers fixedly connected to the arc portion. A fixed shaft is fixedly connected between the two cantilevers. The traction frame includes a bushing sleeved outside the fixed shaft. A pair of fork arms are fixedly connected to the outer side surface of the bushing. Each upper end of the fork arms has a swing arm. The upper ends of the two swing arms respectively cooperate with the two connecting shafts to form a rotating pair. A movable shaft is fixedly connected between the two swing arms, which cooperates with the movable end of the air cylinder to form a rotating pair, avoiding movement interference between components.

[0008] As a preference, after the end of the connecting shaft passes through the guide rail frame and the swing arm, a limit ring is fixedly connected. After the end of the follower shaft passes through the guide rail frame, a limit ring is also fixedly connected, improving the smoothness when the turning table slides.

[0009] As a preference, a sunk groove is formed on the upper surface of the turning table. A lifting frame is fixedly connected to the inner wall of the sunk groove of the turning table. The replaceable plate is placed in the sunk groove and on the lifting frame, providing sufficient supporting force for the replaceable plate.

[0010] As a preference, countersunk holes are formed at the corners of the replaceable plate. Internal screw holes are formed at the corners of the lifting frame. The connecting piece passes through the countersunk hole and is in threaded cooperation with the internal screw hole. The upper surface of the replaceable plate is flush with the upper surface of the turning table. The upper end surface of the connecting piece is not higher than the upper surface of the replaceable plate, ensuring the flatness of the upper surfaces of the turning table and the replaceable plate.

[0011] As a preference, the configuration frame further includes a fixed plate fixedly connected to the two guide rail frames at the same time. A pair of support frames are fixedly connected to the fixed plate. The pressing assembly includes a hot pressing roller rotatably connected between the two support frames. A reduction motor is fixedly connected to the outer side surface of the support frame, adapted to drive the hot pressing roller to rotate. A connection hole is also formed on the fixed plate for connecting pieces such as bolts to pass through to fix the entire packaging mechanism.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows:

[0013] (1) By providing replaceable plates with various models, the packaging mechanism can be adapted to various lozenge packages with different sizes and shapes, improving the utilization rate of a single packaging mechanism and reducing the configuration cost of the packaging mechanism.

[0014] (2) By designing the housing plate on the guide rail frame with a straight portion and an arc portion, after the lozenges are packaged, they can be automatically thrown out of the packaging mechanism by their own inertia. As long as the force of each throw is reasonably controlled, the medicine plates of the lozenges can be automatically stacked, reducing the labor intensity of manual stacking.

[0028] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence.

[0029] The terms "comprising" and "having" and any variations thereof in the description and claims of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that comprises a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0030] As Figure 1-10 shown in the packaging mechanism of the lozenge, it includes a fixed configuration frame 1. A pair of parallel guide rail frames 2 are fixedly connected to the configuration frame 1. The two guide rail frames 2 are symmetric about the vertical plane structure. Each guide rail frame 2 includes an integral straight part 201 and an arc part 202. The two straight parts 201 are on the same horizontal plane, and the arc part 202 bends downward from the end of the straight part 201. The straight part 201 and the arc part 202 have continuous chutes that penetrate the inner and outer sides of the straight part 201 and the arc part 202. The two guide rail frames 2 commonly slidably connect a flipping table 7 through the chutes. Specifically: The outer side of the flipping table 7 has a pair of coaxial connection shafts 701 and a pair of coaxial follower shafts 702. The two connection shafts 701 are close to one side of the flipping table 7, and the two follower shafts 702 are close to the opposite side of the flipping table 7. Therefore, the axes of the connection shafts 701 and the follower shafts 702 are only parallel and do not coincide. The connection shafts 701 and the follower shafts 702 are both engaged with the chutes of the guide rail frames 2 to form a sliding pair, thereby restricting the degrees of freedom of movement of the flipping table 7 and allowing the flipping table 7 to only move along the extending direction of the guide rail frames 2.

[0031] A cylinder 5 is provided at the bottom of the configuration rack 1, which is used to drive the flipping table 7 to slide along the straight part 201 and the arc part 202. And due to the change in the direction of the guide rail rack 2, the angle of the flipping table 7 relative to the horizontal plane will change continuously during the sliding process. The specific structure of the configuration rack 1 includes a cross beam 102 fixedly connected to the two guide rail racks 2 at the same time. A cylinder 5 is rotatably connected to the center of the cross beam 102, and the end of the cylinder barrel of the cylinder 5 is rotatably connected to the cross beam 102. A limiting frame 3 is fixedly connected to the lower end of the arc part 202. The limiting frame 3 can maintain the stability of the relative distance at the lower end of the arc part 202. The upper end of the limiting frame 3 is rotatably connected to a traction frame 4. Therefore, the traction frame 4 can swing. The upper end of the traction frame 4 is rotatably connected to the connecting shaft 701, and the movable end of the cylinder 5 is rotatably connected to the traction frame 4, which is used to drive the traction frame 4 to swing.

[0032] More specifically, the limiting frame 3 includes a pair of cantilever beams 301 respectively fixedly connected to the two arc parts 202. A horizontal fixed shaft 302 is fixedly connected between the two cantilever beams 301. The fixed shaft 302 is close to the upper end of the cantilever beam 301. The traction frame 4 includes a shaft sleeve 401 sleeved outside the fixed shaft 302. The shaft sleeve 401 rotates relative to the fixed shaft 302. A pair of fork arms 402 are fixedly connected to the outer side surface of the shaft sleeve 401. The two fork arms 402 are also symmetrical to each other. The upper end of each fork arm 402 has a swing arm 403 in the vertical plane. The upper ends of the two swing arms 403 are respectively matched with the two connecting shafts 701 to form a rotating pair, which is beneficial to ensuring the force balance during the movement process. An activity shaft 404 is also fixedly connected between the two swing arms 403. The activity shaft 404 is close to the position where the swing arm 403 and the fork arm 402 transition. The activity shaft 404 is used to cooperate with the movable end of the cylinder 5 to form a rotating pair, so as to avoid movement interference. The end of the connecting shaft 701 passes through the guide rail rack 2 and the swing arm 403 and then is fixedly connected with a limiting ring 705, which is used to inhibit the relative movement of the connecting shaft 701. The end of the follower shaft 702 also passes through the guide rail rack 2 and is fixedly connected with a limiting ring 705. This limiting ring 705 can slide along the outer side surface of the guide rail rack 2, thereby improving the smoothness of the movement of the flipping table 7.

[0033] The upper surface of the turning table 7 is fixedly connected with a replaceable plate 8 through a connecting member 9. By disassembling the connecting member 9, the replaceable plate 8 can be conveniently replaced. A sunk groove 703 is formed on the upper surface of the turning table 7, and the replaceable plate 8 is placed in the sunk groove 703. A lifting frame 704 is fixedly connected to the inner wall of the sunk groove 703 of the turning table 7. The replaceable plate 8 is exactly located on the lifting frame 704 and is subjected to a supporting force. A countersunk hole 803 is formed at the corner of the replaceable plate 8. Correspondingly, an internal thread hole 706 is formed at the corner of the lifting frame 704. The connecting member 9 is usually an internal hexagonal bolt, which passes through the countersunk hole 803 and is threadedly engaged with the internal thread hole 706 and tightened. The upper surface of the replaceable plate 8 is flush with the upper surface of the turning table 7, and the upper end surface of the connecting member 9 shall not be higher than the upper surface of the replaceable plate 8. In this way, when the replaceable plate 8 and the turning table 7 move synchronously, the upper surface will be very flat, effectively reducing the movement interference with other components.

[0034] A pressing component 6 is further arranged on the configuration rack 1, which is used to press the two parts of the packaging body of the tablet together, such as common plastic plates and aluminum foils. The configuration rack 1 further includes a fixing plate 101 fixedly connected to the two guide rail racks 2 at the same time. There are usually two fixing plates 101. A pair of support frames 104 are fixedly connected to the two fixing plates 101 together. The two guide rail racks 2 are both located between the two support frames 104. The pressing component 6 includes a hot pressing roller 601 rotatably connected between the two support frames 104, which can press the aluminum foil tightly on the plastic plate. A reduction motor 602 is fixedly connected to the outer side surface of the support frame 104. The output end of the reduction motor 602 is coaxially connected to the hot pressing roller 601 and is used to drive the hot pressing roller 601 to rotate. A connection hole 103 is further formed on the fixing plate 101 for a structure such as a bolt to pass through to fix the whole packaging mechanism on the rack of the packaging equipment.

[0035] Working principle: A medicine plate groove 801 is formed on the upper surface of the replaceable plate 8, which can exactly accommodate plastic tablets. A fitting hole 802 is formed on the inner bottom surface of the medicine plate groove 801 of the replaceable plate 8, which fits with the concave part of the plastic tablet up and down. Since there are several models of the replaceable plate 8, and only the size, shape and arrangement of the fitting holes 802 are different between different models of the replaceable plate 8, when the size and shape of the medicine lozenge change and it is necessary to replace the plastic tablet used, the replaceable plate 8 can be replaced to make the packaging mechanism adapt to the packaging body.

[0036] During operation, first place the plastic sheet with a concave structure in the medicine plate groove 801 of the replaceable plate 8, and then put the medicine lozenges into the grooves of the plastic sheet. When all the grooves on the plastic sheet are filled with lozenges, the plastic sheet can be covered with aluminum foil. Start the cylinder 5 to drive the replaceable plate 8 to slide from the straight part 201 of the guide rail frame 2 to the arc part 202 through the traction frame 4. When the replaceable plate 8 passes under the hot pressing roller 601, the aluminum foil will be hot-pressed and adsorbed on the upper surface of the plastic plate, so as to encapsulate the lozenges between the plastic plate and the aluminum foil. Since a centrifugal force will be generated when the packaged product deflects from the horizontal direction to the inclined direction, when the packaged product loses the restrictive effect of the hot pressing roller 601, it will be thrown out of the medicine plate groove 801 by its own inertia. After the blanking is completed, the turning table 7 and the replaceable plate 8 will return to the initial position under the drive of the cylinder 5 to perform the next round of packaging operation. Since the action of throwing out the lozenge medicine plate is the same each time, the trajectories are also roughly the same, so this action can be used to automatically stack the lozenge medicine plates, reducing the labor cost.

[0037] The above describes the basic principle, main features and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application.
