Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medicine packaging, in particular to a medicine packaging film sealing device capable of preventing medicine clamping. BACKGROUND

[0002] As a special commodity, medicine is closely related to human health and life. How to keep the performance of medicine intact plays a decisive role in its packaging. The main role of medicine is to protect and improve human health, thus determining the main role of medicine packaging, which is to ensure the safety, effectiveness and stability of medicine for a long time under various conditions. In recent years, due to technological progress, human concern for health and the enhancement of environmental awareness, medicine packaging is developing towards safety, comprehensiveness and pollution-free. The world medicine packaging is developing towards diversification, diversification of packaging materials, emphasis on safety and environmental protection. In the use of materials, medical packaging tends to use multi-layer composite film to enhance strength.

[0003] The existing medicine packaging generally moves the composite film by guiding roll, and forms a medicine inlet and a medicine storage space at a specific position for medicine storage and storage. Medicine is continuously thrown towards the medicine storage space, and the composite film is also output to the film sealing device. The film sealing device seals the medicine inlet, and then cuts the sealed composite film by using a cutting device, thereby completing the whole process of medicine packaging. During continuous medicine throwing and film sealing, since medicine is continuously thrown, it may cause the medicine in the medicine storage space to accumulate too high, resulting in the medicine being thrown into the medicine storage space formed by the composite film. Since medicine is continuously thrown, the medicine in the medicine storage space may accumulate too high, causing the film sealing device to clamp medicine during film sealing, resulting in medicine damage and waste, even machine damage, packaging failure and other problems.

[0041] Please refer to Figures 1 to 8 The embodiment provides a medicine packaging and sealing film device capable of preventing medicine clamping, comprising:

[0042] a mounting frame 1;

[0043] a film output forming mechanism 2 arranged on the mounting frame 1 and used for outputting a sealing film 213 and forming the sealing film 213 to form a medicine storage space;

[0044] a film sealing mechanism 3 arranged on the mounting frame 1 and located below the medicine storage space, the film sealing mechanism 3 being provided with a variable gap, and the sealing film 213 and the medicine being capable of passing through the variable gap;

[0045] a medicine hopper 4 arranged on the mounting frame 1 and having a medicine feeding port extending to the medicine storage space;

[0046] a medicine pushing mechanism 5 comprising a sealing motor 51, a first transmission assembly 52, a cam 53, a clamping pushing piece 54, a bearing assembly 55 and a medicine pushing rod 56, the sealing motor 51, the first transmission assembly 52 and the bearing assembly 55 being all fixed on the mounting frame 1, the first transmission assembly 52 being connected with the sealing motor 51 and the cam 53 respectively, so as to transmit the rotating movement of the sealing motor 51 to the cam 53 and drive the cam 53 to rotate, the clamping pushing piece 54 being fixedly connected with the medicine pushing rod 56, the medicine pushing rod 56 passing through the bearing assembly 55 and being rotatably connected with the bearing assembly 55, one end of the clamping pushing piece 54 being in contact with the cam 53, and the clamping pushing piece 54 being capable of swinging with the rotation of the cam 53 to drive the medicine pushing rod 56 to swing with the swinging of the clamping pushing piece 54.

[0047] The technical scheme provided by the application is mainly realized by cooperation of the film output forming mechanism 2, the film packaging mechanism 3, the medicine hopper 4 and the medicine pushing mechanism 5, realizes packaging of the medicine, and effectively avoids the medicine continuously falling into the medicine storage space, causing the medicine accumulation height to be too high and the medicine to be clamped. In detail, first, the film output forming mechanism 2 is used to store and output the film, and in the output process, the packaging film 213 is shaped when it is conveyed to a specific position, forming a medicine storage space; then, the packaging film 213 passing through the variable gap is packaged by the film packaging mechanism 3, and the specific packaging method is to change the gap to realize the medicine passing through the film packaging mechanism 3 and the film passing through the film packaging mechanism 3 and being extruded and packaged by the film packaging mechanism 3; secondly, when the medicine falls into the medicine storage space through the medicine hopper 4, a part of the medicine pushing mechanism 5 can swing in the medicine storage space, thereby pushing the medicine accumulated in the medicine storage space to one side, reducing the accumulation height, effectively avoiding the clamping of the medicine due to the high accumulation height of the medicine, and effectively avoiding the problems of medicine damage and waste, machine damage, packaging failure and the like caused by clamping. For the medicine pushing mechanism 5, it mainly rotates by using the packaging motor 51, and then relies on the first transmission assembly 52 to transmit the rotation of the packaging motor 51 to the cam 53. The cam 53 rotates, and under the action of the structure of the cam 53 itself, the clamping pushing piece 54 swings with the rotation of the cam 53, and the cam 53 only needs to rotate in one direction, that is, the packaging motor 51 does not need to be reversed, so as to realize the back-and-forth swinging of the clamping pushing piece 54, thereby realizing the back-and-forth swinging of the medicine pushing mechanism and realizing the medicine pushing function. Compared with repeatedly switching the packaging motor 51 to control the clamping pushing piece 54 to swing back and forth, the control structure is simpler, only needs to control the continuous rotation of the packaging motor 51, and is also beneficial to prolong the service life of the packaging motor 51.

[0048] See Figure 2 and Figure 3 For the cam 53, it is a rhombus shape with different long and short side lengths, and each corner of the rhombus is arc-shaped, so that the rotation of the cam 53 can smoothly drive the clamping pushing piece 54 to swing with the cam 53. Specifically, when the edge of the cam 53 corresponding to the short side of the cam 53 rotates upward, the end of the clamping pushing piece 54 in contact with the cam 53 is in a hanging state, and when the cam 53 continues to rotate, the edge of the cam 53 gradually rises upward, and the clamping pushing piece 54 swings under the pushing action of the cam 53.

[0049] For the clamping and pushing piece 54, it includes a fixed part and a pushing part which is integrally formed at the bottom of the fixed part. The fixed part is fixedly connected with the pushing rod 56, and the pushing part is triangular and arc-shaped at one end away from the fixed part, and the arc-shaped end is in contact with the cam 53. By setting the one end of the pushing part as arc-shaped, when the cam 53 rotates, the arc-shaped part of the pushing part in contact with the cam 53 can swing along the edge of the cam 53, and based on the arc-shaped rhombus shape of the cam 53, the pushing part will fall back after swinging to a certain angle, and thus the reciprocating swinging motion of the clamping and pushing piece 54 is realized. Moreover, the arc-shaped structure is beneficial to the movement of the clamping and pushing piece 54 on the cam 53 and reduces the friction between the clamping and pushing piece 54 and the cam 53.

[0050] Further, the medicine pushing mechanism 5 further includes a tension spring 57, one end of which is connected with the fixed part and the other end of which is connected with the bearing assembly 55. The tension spring 57 elastically deforms with the rotation of the clamping and pushing piece 54. When the clamping and pushing piece 54 is pushed by the rotation of the cam 53, the clamping and pushing piece 54 starts to swing to push the medicine in the medicine storage space to one side, so as to reduce the height of the medicine accumulation in the medicine storage space. At this time, because of the swinging of the clamping and pushing piece 54, the tension spring 57 is in a stretched state to avoid that the swinging amplitude of the clamping and pushing piece 54 is too large or unstable due to inertia. When the cam 53 continues to rotate and the long side rotates from the top to the bottom along the corresponding edge, the clamping and pushing piece 54 starts to fall back from the highest point of the swing. Similarly, the tension spring 57 also gives the clamping and pushing piece 54 a pulling force to swing back, and can also avoid that the swinging back angle of the clamping and pushing piece 54 is too large.

[0051] In some embodiments, the pushing rod 56 includes a transmission rod 561 and a swinging rod 562, one end of the transmission rod 561 is perpendicularly connected with one end of the swinging rod 562, so that the pushing rod 56 is L-shaped. The end of the transmission rod 561 away from the swinging rod 562 penetrates through the bearing assembly 55 and is fixedly connected with the clamping and pushing piece 54, and the end of the swinging rod 562 away from the transmission rod 561 extends into the medicine storage space and can reciprocatingly swing toward the obliquely downward direction away from the film output forming mechanism 2. By setting the pushing rod 56 as L-shaped and having the transmission rod 561 and the swinging rod 562, the transmission rod 561 is mainly used for transmitting the rotating motion of the packaging motor 51, and the swinging rod 562 receives the rotating motion and changes the rotating motion into swinging motion. Correspondingly, the rotation of the packaging motor 51 is converted into the reciprocating swinging motion of the swinging rod 562, so that the continuous medicine pushing action is realized.

[0052] In some embodiments, please refer to Figure 2The first transmission assembly 52 comprises a first synchronous pulley 521, a second synchronous pulley 522, a transmission belt 523, a transmission seat 524 and a synchronous shaft 525. The first synchronous pulley 521 is fixedly connected to the output end of the packaging motor 51. The transmission seat 524 is fixed to the mounting frame 1. The second synchronous pulley 522 is arranged on the transmission seat 524. The synchronous shaft 525 penetrates through the second synchronous pulley 522 and is fixedly connected with the second synchronous pulley 522. One end of the synchronous shaft 525 is fixedly connected with the cam 53. The two ends of the transmission belt 523 are sleeved with the first synchronous pulley 521 and the second synchronous pulley 522 respectively. By using the first synchronous pulley 521, the second synchronous pulley 522 and the transmission belt 523, the rotation of the packaging motor 51 can be effectively transmitted to the second synchronous pulley 522. The rotation of the second synchronous pulley 522 drives the synchronous shaft 525 to rotate, and the synchronous shaft 525 drives the cam 53 to rotate, so as to realize the transmission of the rotation of the motor.

[0053] Further, the first transmission assembly 52 further comprises a sun seat and a sun wheel 526. The sun seat is fixed to the transmission seat 524. The sun wheel 526 is fixedly connected with the sun seat. The sun wheel 526 is located between the first synchronous pulley 521 and the second synchronous pulley 522. A part of the transmission belt 523 is overlapped on the sun wheel 526. By arranging the sun wheel 526, the transmission distance of the transmission belt 523 can be effectively increased, and the distance between the two synchronous pulleys in the air can be shortened, which is beneficial to improve the stability of the transmission of the transmission belt 523.

[0054] In some embodiments, referring to Figure 4 The film output assembly 21 is arranged on the mounting frame 1 and is used for storing and outputting packaging films 213. In the embodiment, the packaging films 213 are all multi-layer composite films.

[0055] The film output assembly 21 is arranged on the mounting frame 1 and is used for storing and outputting packaging films 213. In the embodiment, the packaging films 213 are all multi-layer composite films.

[0056] The film forming assembly 22 is arranged on the mounting frame 1 and is located below the film output assembly 21. The film forming assembly 22 is used for receiving the packaging films 213 output from the film output assembly 21 and separating the packaging films 213 into first sub-films and second sub-films. The first sub-films and the second sub-films are attached to a part of the film forming assembly 22 and form the medicine storage space. The medicine feeding port of the medicine hopper 4 is located on one side of the film forming assembly 22 and extends into the medicine storage space. The part of the medicine pushing mechanism 5 used for swinging is located between the medicine hopper 4 and the film forming assembly 22 and extends into the medicine storage space.

[0057] The embodiment mainly realizes storage and output of the packaging film 213 through the film output assembly 21, so that the packaging film 213 can be continuously and continuously supplied; then the packaging film 213 is separated into the first sub-film and the second sub-film through the film forming assembly 22, and the first sub-film and the second sub-film are attached to the film forming assembly 22, the shape and thickness of the film forming assembly 22 are utilized to separate the first sub-film and the second sub-film and arrange them at intervals, so that a medicine storage space with an opening can be defined between the two sub-films, so that the medicine can fall into the medicine storage space. For the medicine falling into the medicine storage space, the medicine in the medicine storage space is stirred by the medicine stirring rod 56 extending into the medicine storage space, so that the medicine accumulated in the height direction is stirred towards the obliquely downward, thereby reducing the accumulation height.

[0058] Further, the film output assembly 21 comprises:

[0059] The packaging barrel 211 is fixed to the mounting frame 1, and the surface of the packaging barrel 211 can roll. Specifically, the packaging barrel 211 has a rotating shaft and a roller, the rotating shaft is fixedly connected to the mounting frame 1, and the roller is rotatably sleeved on the rotating shaft, so that the surface of the packaging barrel 211 can roll.

[0060] A plurality of guide rollers 212 are sequentially arranged on the mounting frame 1 towards the film forming assembly 22, and the packaging film 213 will sequentially pass through the plurality of guide rollers 212 and be lapped on the guide rollers 212 when being output. The rolling and bearing capacity of the guide rollers 212 can reduce the distance of the packaging film 213 being suspended, avoid the packaging film 213 relaxing due to lack of support, and the rolling of the guide rollers 212 can also reduce the hindering effect of the guide rollers 212 on the movement of the packaging film 213 as much as possible when bearing and guiding, so that the movement of the packaging film 213 is more smooth.

[0061] The packaging film 213 is wrapped on the packaging barrel 211, and one end of the packaging film 213 sequentially passes through the plurality of guide rollers 212 and extends through the film packaging mechanism 3, and the film packaging mechanism 3 applies an extrusion and pulling force to the packaging film 213. By wrapping the packaging film 213 on the packaging barrel 211, a large amount of packaging film 213 can be effectively stored for continuous output, and one end of the packaging film 213 is fixed on the packaging barrel 211, and the other end is pulled by the film packaging mechanism 3, so that the packaging film 213 always maintains a tension state during the working stage, which is beneficial to the cutting and packaging of the packaging film 213 and can effectively avoid the occurrence of the tape jamming caused by the relaxation of the packaging film 213. The extrusion force applied by the film packaging mechanism 3 to the packaging film 213 is mainly used for packaging, and the specific structure on the film packaging mechanism 3 is used to extrude and package the packaging film 213.

[0062] In the embodiment, the output path of the packaging film 213 is downward, because the film packaging mechanism 3 for packaging the pulling packaging film 213 is arranged below the packaging cylinder 211, and the film packaging mechanism 3 mainly plays a role of providing power to the packaging film 213 to make it separate from the packaging cylinder 211 and package the packaging film 213. Correspondingly, a plurality of guide rollers 212 are arranged in sequence along the packaging path downward. It should be noted that the number of the guide rollers 212 and the specific position of the arrangement are selected according to the actual situation, and are not limited, as long as the guide rollers 212 can play a role of bearing and guiding the packaging film 213.

[0063] In some embodiments, referring to Figure 5 , the film output assembly 21 further comprises a film pressing assembly 214. One end of the film pressing assembly 214 is rotatably connected to the mounting frame 1 and located on one side of the packaging cylinder 211, and the other end is placed on the packaging film 213 wrapped on the packaging cylinder 211 and applies pressure to the packaging film 213.

[0064] The embodiment mainly uses the film pressing assembly 214 to press and hold the packaging film 213 wrapped on the packaging cylinder 211, so that the packaging film 213 can be output flat from the packaging cylinder 211 under the action of the film pressing assembly 214 when feeding and outputting, effectively avoiding the problems of loose packaging film 213, causing the packaging film 213 to be jammed, damaging the mechanical equipment and being not conducive to slitting the packaging film 213 during the conveying process. Specifically, the film pressing assembly 214 is mainly used to press and hold the packaging film 213 wrapped on the packaging cylinder 211, and when the packaging film 213 is output from the packaging cylinder 211, the packaging film 213 can still maintain tension under the pressure of the film pressing assembly 214 and the guiding action of the plurality of guide rollers 212, of course, and the force of the pulling output of the packaging film 213, so as to effectively avoid the problems of packaging film 213 jamming and being not conducive to slitting. In addition, by rotatably connecting the film pressing assembly 214 with the mounting frame 1, when the packaging film 213 on the packaging cylinder 211 gradually decreases with use, and the thickness of the packaging film 213 gradually decreases, the film pressing assembly 214 can gradually rotate with the decrease of the thickness of the packaging film 213, so as to ensure that the film pressing assembly 214 can always press and hold the packaging film 213, so that the packaging film 213 can maintain tension and be flat when separating from the packaging cylinder 211 under the pressure action of the film pressing assembly 214.

[0065] Further, referring to Figure 5 , the film pressing assembly 214 specifically comprises:

[0066] A rotating rod 2141 is rotatably connected with the mounting frame 1 and located at one side of the packaging cylinder 211, and the rotating direction of the rotating rod 2141 is towards the packaging cylinder 211;

[0067] A counterweight 2142 is connected with the rotating rod 2141 at one end close to the packaging cylinder 211, and the counterweight 2142 is located above the packaging film 213 on the packaging cylinder 211;

[0068] A connecting piece 2143 is connected with the counterweight 2142 and located above the packaging film 213 on the packaging cylinder 211;

[0069] A pressing roller 2144 is fixedly connected with the connecting piece 2143 and in contact with the packaging film 213 on the packaging cylinder 211, and the pressing roller 2144 can roll with the output of the packaging film 213.

[0070] The pressing roller 2144 is naturally pressed on the packaging film 213 wrapped on the packaging cylinder 211 under the action of its own gravity and the counterweight 2142 by cooperating with the counterweight 2142, so that the packaging film 213 can be pressed when it is output from the packaging cylinder 211, thereby keeping the output packaging film 213 flat and cooperating with the force of pulling the packaging film 213 below to ensure that the packaging film 213 is always in a tension state. It should be noted that the packaging film 213 on the packaging cylinder 211 will gradually decrease in thickness during use, and the rotating rod 2141 will gradually rotate with the decrease of the thickness of the packaging film 213 by rotating the rotating rod 2141 and gravity in this embodiment, so that the pressing roller 2144 provided on the rotating rod 2141 can always be in contact with the packaging film 213 on the packaging cylinder 211 to form a pressing action on the packaging film 213, and will not be affected by the decrease of the thickness of the packaging film 213, and can continuously press the packaging film 213.

[0071] It is also to be noted that the connecting piece 2143 is mainly used to connect the compression roller 2144 and the rotating rod 2141, and the structure of the connecting piece 2143 can be set according to the relative position of the rotating rod 2141 and the packaging cylinder 211, so that the surface of the compression roller 2144 can always cover the packaging film 213 of the packaging cylinder 211, and the rolling direction of the compression roller 2144 is in the same plane as the rolling direction of the packaging cylinder 211. The compression roller 2144 has a shaft and a roller, the roller is rotatably sleeved on the shaft, and the shaft is fixedly connected with the connecting piece 2143, so that the roller can roll with the output of the packaging film 213, and the packaging film 213 is flattened and output more smoothly.

[0072] In some embodiments, referring to Figure 4 and Figure 6 , the film forming assembly 22 comprises:

[0073] a forming mounting base 221 fixed to the mounting frame 1;

[0074] a forming die 222 fixedly connected with the forming mounting base 221, the first sub-film and the second sub-film are respectively attached to both sides of the forming die 222 to wrap the forming die 222, and the first sub-film and the second sub-film form the medicine storage space through the forming die 222. The forming die 222 is located below the guide roller 212 and is used to receive the packaging film 213 extended from the guide roller 212 and separate the packaging film 213 into the first sub-film and the second sub-film. The forming die 222 is in the shape of a water droplet, and the surface is in the form of a smooth arc, so as to facilitate the attachment of the first sub-film and the second sub-film. Moreover, the thickness of the forming die 222 gradually decreases along the direction in which the packaging film 213 is output towards the forming die 222, i.e. from top to bottom, and the thickness of the forming die 222 also gradually decreases along the direction from left to right, so that the distance between the first sub-film and the second sub-film near the left side of the forming module is greater than the distance between the first sub-film and the second sub-film near the right side of the forming module, so as to form a medicine storage space with an opening.

[0075] In some embodiments, the medicine feeding hopper 4 is provided on the mounting frame 1 and located at the medicine storage space, so as to feed medicine into the medicine storage space defined by the first sub-film and the second sub-film. Specifically, the medicine feeding hopper 4 is provided on the left side of the forming module, and the medicine feeding port of the medicine feeding hopper 4 is arranged between the first sub-film and the second sub-film, so as to ensure that the medicine can smoothly fall into the space formed by the first sub-film and the second sub-film.

[0076] Further, the forming die 222 is provided with a medicine guiding groove on one side surface of the medicine feeding hopper 4, and the inner wall of the medicine guiding groove is arc-shaped. By setting the medicine guiding groove as arc-shaped, it is beneficial to prevent the medicine from being scraped from the medicine guiding groove and reduce the collision between the medicine and the inner wall of the medicine guiding groove.

[0077] In some embodiments, referring to Figure 7 and Figure 8 For the film packaging mechanism 3, it comprises:

[0078] The motor mounting seat 31 is fixed on the mounting frame 1, and the packaging motor 51 is fixedly connected with the motor mounting seat 31.

[0079] The second transmission assembly 6;

[0080] The packaging assembly 33 has a medicine leaking state and a film sealing state, and is fixed on the mounting frame 1. The packaging assembly 33 is in transmission connection with the output end of the packaging motor 51 through the second transmission assembly 6, so that the packaging assembly 33 is switched between the medicine leaking state and the film sealing state by the rotation of the packaging motor 51. The medicine leaking state and the film sealing state are mainly distinguished by the size of the variable gap, that is, when the variable gap is sufficient for the medicine to pass through, it is in the medicine leaking state; when the variable gap is only sufficient for the packaging film 213 to pass through, it is in the film sealing state.

[0081] Further, for the packaging assembly 33, it comprises:

[0082] The packaging seat 331 is fixed on the mounting frame 1, and the first packaging roller 332 and the second packaging roller 333 are both rotationally arranged in the packaging seat 331. The first packaging roller 332 and the second packaging roller 333 are arranged in a symmetrical manner and define the variable gap. The variable gap comprises a first gap 334 and a second gap 335, and the first gap 334 and the second gap 335 are switched by the rotation of the first packaging roller 332 and the second packaging roller 333. The second gap 335 is larger than the first gap 334. When the packaging assembly 33 is in the film sealing state, the first gap 334 exists between the first packaging roller 332 and the second packaging roller 333, and when the packaging assembly 33 is in the medicine leaking state, the second gap 335 exists between the first packaging roller 332 and the second packaging roller 333.

[0083] In detail, the first packaging roller 332 and the second packaging roller 333 have the same structure and working principle. The first packaging roller 332 is dumbbell-shaped and has a first packaging wheel, a second packaging wheel and a gap connecting column. The first packaging wheel and the second packaging wheel are oppositely arranged, and the gap connecting column is arranged between the first packaging wheel and the second packaging wheel and fixedly connects the first packaging wheel and the second packaging wheel. The projection of the gap connecting column on the first packaging wheel towards the second packaging wheel is located in the projection of the first packaging wheel and on the surface of the second packaging wheel, and the projection of the gap connecting column is hexagonal. The thickness of the gap connecting column is smaller than the length and width of the gap connecting column, that is, the gap connecting column is a flat hexagonal column. Since the first packaging wheel and the second packaging wheel have the same structure and are symmetrically arranged, when the first packaging wheel and the second packaging wheel rotate relative to each other, the gap between the first packaging wheel and the second packaging wheel changes. Specifically, when one side of the width direction of the gap connecting column of the first packaging wheel and one side of the width direction of the gap connecting column of the second packaging wheel rotate to the closest distance, the gap between the first packaging wheel and the second packaging wheel is the first gap 334. Similarly, when one side of the thickness direction of the gap connecting column of the first packaging wheel and one side of the thickness direction of the gap connecting column of the second packaging wheel rotate to the closest distance, the gap between the first packaging wheel and the second packaging wheel is the second gap 335.

[0084] In order to better understand the working principle of the first packaging roller 332 and the second packaging roller 333 switching between the first gap 334 and the second gap 335, the following is a simple example:

[0085] Assuming that the current first encapsulation roller 332 and the second encapsulation roller 333 are in the position of the first gap 334, and define the current first encapsulation roller 332 and the second encapsulation roller 333 as rotating 0°, then under the driving of the encapsulation motor 51, the first encapsulation roller 332 and the second encapsulation roller 333 move relatively, and when the first encapsulation roller 332 and the second encapsulation roller 333 both rotate 90°, and it needs to be pointed out that the rotating directions of the first encapsulation roller 332 and the second encapsulation roller 333 are opposite, at this time, the first encapsulation roller 332 and the second encapsulation roller 333 are in the position of the second gap 335. Every 90° rotation, the first gap 334 and the second gap 335 are switched once. When the encapsulation film 213 first enters the first gap 334, the first encapsulation roller 332 and the second encapsulation roller 333 continue to rotate, driving the encapsulation film 213 to continue to move downward, and the bottom edge of the encapsulation film 213 is encapsulated, and then it will be switched to the second gap 335, at this time, the medicine can pass through the second gap 335 to the lower side of the first encapsulation roller 332 and the second encapsulation roller 333, and switch to the first gap 334 again, and the gap connecting column in the two encapsulation rollers encapsulates the top edge of the encapsulation film 213 at the first gap 334, and thus the encapsulation of a bag of medicine is completed. It also needs to be pointed out that the gap between the first encapsulation wheel and the second encapsulation wheel always maintains a gap that allows only the encapsulation film 213 to pass through, and continuously encapsulates the side edge of the encapsulation film 213, which is not affected by the gap switching of the gap connecting column, so as to ensure that the side edge of the packaging bag formed by the encapsulation film 213 is completely sealed.

[0086] For the first encapsulation wheel and the second encapsulation wheel, a plurality of encapsulation teeth are arranged on the surfaces thereof, and the encapsulation teeth between the two encapsulation wheels are engaged, so as to achieve the encapsulation and pulling of the side edge of the encapsulation film 213 located between the two encapsulation wheels.

[0087] It also needs to be pointed out that for the foregoing second transmission assembly 6, gear transmission is adopted in the embodiment, and the rotation of the encapsulation motor 51 is transmitted to the first encapsulation roller 332 through a plurality of gears, and the rotating movement of the first encapsulation roller 332 is synchronously and reversely transmitted to the second encapsulation roller 333 through gear cooperation, so as to realize the reverse synchronous rotation of the first encapsulation roller 332 and the second encapsulation roller 333. By using the second transmission assembly 6, the reverse synchronous movement of the two encapsulation rollers driven by one encapsulation motor 51 can be realized, and compared with using two motors to drive two encapsulation rollers respectively, the synchronization effect is better and the cost is lower.

[0088] And, the setting of the packaging motor 51 through the first transmission assembly 52 and the second transmission assembly 6 can synchronously transmit the rotation of the packaging motor 51 to the packaging assembly 33 and the clamping paddle 54. Through the setting of one packaging motor 51, the synchronous rotation of the clamping paddle 54 and the packaging assembly 33 can be realized, which improves the synchronism during the operation of the machine and reduces the manufacturing cost and the control cost.

[0089] In some embodiments, referring to Figure 9 , the film packaging mechanism 3 further comprises a packaging sensor 34 and a packaging induction sheet 35, the packaging sensor 34 is arranged on the motor mounting seat 31, the packaging induction sheet 35 is fixed to the output end of the packaging motor 51 to rotate with the rotation of the packaging motor 51, and the detection position of the packaging sensor 34 is located on the rotation path of the packaging induction sheet 35. Through the cooperation of the packaging sensor 34 and the packaging induction sheet 35, every time the output end of the packaging motor 51 rotates one circle, the packaging induction sheet 35 will rotate one circle and pass through the packaging sensor 34 once, so as to detect the number of circles of the current packaging motor 51, and the length of the current packaging film 213 and the number of medicine packages can be calculated through the number of circles

[0090] In some embodiments, referring to Figure 1 and Figure 4 , the mounting frame 1 is further provided with a film clamping member 7 and a film detector 8, the film detector 8 is arranged on the film clamping member 7, and the detection end of the film detector 8 faces the direction of the packaging cylinder 211, the film clamping member 7 is arranged on one side of the packaging cylinder 211 and located on the output path of the packaging film 213, when the packaging film 213 passes through the film clamping member, the film detector 8 can detect the existence of the packaging film 213, so as to determine whether there is still packaging film 213 output on the current packaging cylinder 211, for reminding the staff to add the packaging film 213.
