Description

Technical Field

[0001] The present invention relates to an ointment medicine production device, in particular to an ointment tube feeding device of an ointment tube filling device. The present invention also relates to a method for automatically forming a single-layer queue of an ointment tube stack. Background Art

[0002] An ointment tube is a soft tube used to hold paste-like substances. Its material is generally an aluminum tube, an aluminum-plastic composite tube or a plastic tube (such as polyethylene). Medicinal ointment tubes have good insulation properties, are not easy to break, are clean and hygienic, are easy to use, are soft to the touch, and are easy to deform. They have become the preferred packaging material for cream preparations by pharmaceutical manufacturers. They are used to produce commonly used over-the-counter dermatological topical drugs such as urea cream and zinc oxide ointment. As the demand for such drugs continues to increase, pharmaceutical manufacturers need to continuously improve the production efficiency of drugs, so they need to realize mechanical automation in all aspects of drug production.

[0003] In the production process of ointment drugs, one of the links is to fill the cream-like drugs into empty medicinal ointment tubes, and then perform a compression operation on the tail of the ointment tube to close the tail of the ointment tube, thereby preventing the cream-like drugs from leaking out of the tail of the ointment tube, and completing the production of the ointment drugs.

[0004] To realize the automatic filling operation, it is necessary to use a synchronous belt to Figure 1 The multiple ointment tubes shown are pushed to the rotating station in a horizontal posture, and the ointment tube rotating mechanism of the rotating station rotates the ointment tubes 90° clockwise to an inverted posture, and finally transported to the filling station.

[0005] Since the ointment tubes are long and thin tubes, the ointment tubes are stacked in a multi-layer arrangement in the preparation box. Figure 2 The synchronous belt must sequentially convey the ointment tubes arranged in a single layer to the ointment tube rotating mechanism in order to realize the subsequent automated operation, so the ointment tubes need to be formed into a single-layer queue.

[0006] At present, the method of obtaining a single-layer queue of ointment tubes is to use their own gravity to make multiple ointment tubes spit out from the lowest point of the preparation box in sequence. However, since the empty ointment tubes are light in weight, it is difficult for the ointment tubes to be spit out from the preparation box only by relying on their own gravity. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide an ointment tube feeding device for ointment tube filling equipment, which can guide the ointment tubes to be spit out one by one from the discharge port of the preparation box, thereby forming a single-layer queue.

[0008] In order to solve the above technical problems, the technical solution of the ointment tube feeding device of the ointment tube filling equipment of the present invention is:

[0009] It includes a material preparation box, and a base frame inclined downward from left to right is fixedly arranged at the bottom of the material preparation box; the lower end of the base frame extends out of the material preparation box from the right side, and a discharge port is formed between the base frame and the material preparation box; the discharge port of the material preparation box is arranged with a discharge port guiding mechanism; the discharge port guiding mechanism includes a first guiding plate, a second guiding plate, a guide rail and a roller, the first guiding plate is movably connected to the right side wall of the material preparation box; the first guiding plate can swing; the second guiding plate is fixedly connected to the driving shaft; the driving shaft can drive the second guiding plate to swing; a guide groove is provided at the lower edge of the guide rail; the guide rail is connected to the first adjusting block by screws; the first adjusting block is connected to the first support plate; the first support plate is fixedly connected to the first guiding plate; the roller is movably arranged in the guide groove of the guide rail; the wheel axle of the roller is connected to the second adjusting block; the second adjusting block is connected to the second support plate; the second support plate is fixedly connected to the second guiding plate.

[0010] In another embodiment, an initial inclination angle of the second guide plate is smaller than an initial inclination angle of the first guide plate.

[0011] In another embodiment, a guide plate is formed at the bottom of the second guide plate; and a material outlet of the material preparation box is formed between the guide plate and the upper surface of the base frame.

[0012] In another embodiment, the guide plate is parallel to the upper surface of the base frame.

[0013] In another embodiment, the distance between the guide plate and the upper surface of the base frame is greater than one time the diameter of the ointment tube and less than two times the diameter of the ointment tube.

[0014] In another embodiment, one end of the first guide plate is connected to a fixed bracket via a pin shaft, and the fixed bracket is fixedly connected to the right side wall of the material preparation box.

[0015] In another embodiment, the fixing bracket is located above the driving shaft.

[0016] In another embodiment, the first support plate is provided with a first guide groove; the relative positions of the guide rail and the first adjustment block and the first support plate can be adjusted along the first guide groove by the screw.

[0017] In another embodiment, the second support plate is provided with a second guide groove; the relative positions of the roller and the second adjustment block and the second support plate can be adjusted along the second guide groove through the axle of the roller.

[0018] In another embodiment, a weight reduction mechanism is fixedly provided on the left side of the middle portion of the material preparation box.

[0019] In another embodiment, the weight reduction mechanism includes a buffer plate, which extends along an inclined direction; the lower end of the buffer plate is fixedly connected to the guide plate.

[0020] In another embodiment, the inclination angle of the guide plate is greater than the inclination angle of the buffer plate.

[0021] In another embodiment, the base frame is fixedly connected to at least two sliding rods, and the sliding rods extend along the length direction of the base frame; the movable sleeves at both ends of the sliding rods are provided with upper sliding blocks and lower sliding blocks; the upper sliding block is fixedly connected to the upper end of the movable plate, and the lower sliding block is fixedly connected to the lower end of the movable plate; one of the lower sliding blocks or the upper sliding block is fixedly connected to the driving block.

[0022] The present invention also provides a method for automatically forming a single-layer queue of ointment tube stacks, and the technical solution thereof comprises the following steps:

[0023] The first step is to drive the external power source to make the eccentric wheel rotate around its rotation center, thereby driving the driving block to reciprocate and drive the driving shaft to swing;

[0024] In the second step, the driving block drives the movable plate to reciprocate relative to the base frame; the swing of the driving shaft drives the second guide plate and the first guide plate to swing synchronously;

[0025] In the third step, the ointment tubes accumulated in the preparation box move downward from top to bottom; the ointment tubes arrive at the first guiding plate; the ointment tubes that arrive first slide downward along the inclined surface of the first guiding plate to the bottom of the first guiding plate, and the ointment tubes that arrive later are accumulated above the first guiding plate;

[0026] In the fourth step, the first guiding plate moves the ointment tube above it away from the discharge port during the swinging process to prevent the ointment tube from piling up near the discharge port; the ointment tube below the first guiding plate continues to move downward to the movable plate and the bottom frame at the bottom of the preparation box; the reciprocating motion of the movable plate enables the ointment tube to intermittently obtain a driving force toward the discharge port, and the driving force is superimposed on the self-gravity of the ointment tube, so that the ointment tube has a movement tendency toward the discharge port;

[0027] In the fifth step, the ointment tubes under the first guide plate move toward the discharge port to the second guide plate, and the second guide plate pushes the ointment tubes in contact with it away from the discharge port during the swinging process; the ointment tubes at the bottom of the preparation box move toward the discharge port in an orderly manner along their original path, and are spit out from the discharge port in turn, thus forming a single-layer queue behind the discharge port.

[0028] The technical effects that can be achieved by the present invention are:

[0029] The base frame of the present invention is fixedly arranged at the bottom of the material preparation box in an inclined posture. When the movable plate reciprocates relative to the base frame at the bottom of the material preparation box, it can drive multiple ointment tubes in the material preparation box to reciprocate along the inclined direction. In this process, the ointment tube can intermittently obtain a driving force toward the discharge port. The driving force is superimposed on the self-gravity of the ointment tube, so that the ointment tube has a movement tendency toward the discharge port. Therefore, the ointment tube pushing mechanism of the present invention can prompt the ointment tube at the bottom of the material preparation box to move toward the discharge port.

[0030] The present invention is provided with a discharge port guiding mechanism at the discharge port, which changes the movement path of the ointment tube above the discharge port during the swinging process, and pushes the ointment tube above the bottom ointment tube in the direction away from the discharge port, so that the upper ointment tube leaves the discharge port; and the ointment tube at the bottom layer continues to move toward the discharge port under the action of the movable plate, so that the ointment tube at the bottom layer can be spit out from the discharge port in turn, thereby forming a single-layer queue.

[0031] An angle is formed between the first guide plate and the second guide plate of the discharge port guiding mechanism of the present invention, and the first guide plate is located above the second guide plate; the first guide plate can push the ointment tube above the discharge port in the direction away from the discharge port before the ointment tube reaches the discharge port, and only part of the ointment tube located below the first guide plate can move from the bottom of the first guide plate to the discharge port direction, so as to avoid the ointment tubes in the preparation box arriving at the discharge port at the same time and being congested at the discharge port, thereby reducing the guiding pressure of the second guide plate; the second guide plate will push the ointment tubes located above the bottom ointment tubes among the ointment tubes that arrive at the discharge port in the direction away from the discharge port, so that the bottom ointment tubes can be spit out from the discharge port in turn to form a single-layer queue.

[0061] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0062] like Figure 3 As shown, the ointment tube feeding device of the ointment tube filling equipment of the present invention includes a material preparation box 10, and a base frame 1 in an inclined posture is fixedly arranged at the bottom of the material preparation box 10; the lower end of the base frame 1 extends out of the material preparation box 10 from the right side, and a discharge port 11 is formed between the base frame 1 and the material preparation box 10.

[0063] A weight reduction mechanism 12 is fixedly provided on the left side of the middle of the material preparation box 10; Figure 4 As shown, the weight reduction mechanism 12 includes a buffer plate 121, which extends along an inclined direction; the lower end of the buffer plate 121 is fixedly connected to a guide plate 122; the inclination angle of the guide plate 122 is greater than the inclination angle of the buffer plate 121; the bottom of the buffer plate 121 is fixedly connected to a connecting plate 123; the weight reduction mechanism 12 is fixedly connected to the rear side wall of the material preparation box 10 through the connecting plate 123.

[0064] The ointment tube at the bottom of the preparation box 10 needs to bear the weight of all the ointment tubes above it. If there are too many ointment tubes in the preparation box 10, it will be difficult for the ointment tube at the bottom of the preparation box 10 to move. In addition, when loading the ointment tube into the preparation box 10, it is necessary to pour it down from the top of the preparation box 10. Since the height of the preparation box 10 is relatively high, the ointment tube is easily deformed in the process of reaching the bottom from the top of the preparation box 10.

[0065] The present invention is provided with a weight reduction mechanism 12 in the middle of the preparation box 10. When the total height of the ointment tubes stacked in the preparation box 10 is greater than the height of the weight reduction mechanism 12, the ointment tubes higher than the weight reduction mechanism 12 can be carried by the buffer plate 121 of the weight reduction mechanism 12, thereby reducing the pressure on the ointment tubes below. In the process of pouring the ointment tubes downward from the top of the preparation box 10, the ointment tubes first reach the buffer plate 121 of the weight reduction mechanism 12, and then fall along the guide plate 122. In this process, the buffer plate 121 can buffer the fall of the ointment tubes, and make the ointment tubes fall slowly along the inclined surface of the buffer plate 121, so as to avoid the free fall of the ointment tubes causing deformation to the mechanism at the bottom of the preparation box or the ointment tubes themselves; the guide plate 122 can guide the movement of the ointment tubes.

[0066] The bottom of the preparation box 10 is provided with an ointment tube pushing mechanism; Figure 5 , Figure 6 As shown, the ointment tube pushing mechanism includes at least two slide bars 2, which extend along the length direction of the base frame 1 and are fixedly connected to the base frame 1; an upper slide block 3 and a lower slide block 4 are movably sleeved on the slide bars 2; the upper slide blocks 3 of the two slide bars 2 are fixedly connected to the upper end of the movable plate 5, and the lower slide blocks 4 of the two slide bars 2 are fixedly connected to the lower end of the movable plate 5; one of the lower slide blocks 4 is fixedly connected to the driving block 6;

[0067] The length of the movable plate 5 is smaller than the length of the material preparation box 10 , so that the movable plate 5 can reciprocate at the bottom of the material preparation box 10 .

[0068] The material outlet 11 of the material preparation box 10 is provided with a material outlet dredging mechanism; Figure 7 , Figure 8 As shown, the discharge port guiding mechanism includes a first guiding plate 21, one end of the first guiding plate 21 is movably connected to the fixed bracket 14 through the pin shaft 15, and the fixed bracket 14 is fixedly connected to the right side wall of the material preparation box 10; the first guiding plate 21 extends in an inclined direction; the first guiding plate 21 can swing around the pin shaft 15 in the material preparation box 10;

[0069] The bottom of the first guide plate 21 is fixedly connected to the first support plate 22, and the first support plate 22 is provided with a first guide groove; the first guide groove is movably connected to the first adjustment block 23, and the first adjustment block 23 is connected to the guide rail 24 through screws;

[0070] Specifically, the screw of the first adjustment block 23 is inserted into the first guide groove of the first support plate 22, so that the first adjustment block 23 can move along the first guide groove of the first support plate 22;

[0071] A guide groove is formed at the lower edge of the guide rail 24, and a roller 25 is movably arranged in the guide groove; the axle of the roller 25 is fixedly connected to the second adjustment block 26, and the second adjustment block 26 is connected to the second support plate 27; the second support plate 27 can support the first guide plate 21 from below through the movable cooperation between the roller 25 and the guide rail 24, so that the first guide plate 21 has an initial tilt angle;

[0072] Specifically, the roller 25 is movably connected to its axle through a bearing, and the roller 25 can rotate relative to its axle along the guide groove of the guide rail 24; the second support plate 27 is provided with a second guide groove; the axle of the roller 25 is connected to the second adjustment block 26 through a thread; when the axle of the roller 25 is loosened, the initial position of the second adjustment block 26 can be moved along the second guide groove of the second support plate 27, thereby adjusting the initial positions of the roller 25 and the guide rail 24; when the axle of the roller 25 is tightened, the second adjustment block 26 can be fixedly connected to the second support plate 27, thereby maintaining the initial position of the guide rail 24;

[0073] The second support plate 27 is fixedly connected to the second guide plate 28; the second guide plate 28 extends along the inclined direction; and the initial inclination angle of the second guide plate 28 is smaller than the initial inclination angle of the first guide plate 21; specifically, Figure 3 As shown, the angle between the second guide plate 28 and the right side wall 13 of the material preparation box 10 is smaller than the angle between the first guide plate 21 and the right side wall 13 of the material preparation box 10; the second guide plate 28 located above the first guide plate 21 can receive the ointment tube dropped from the guide plate 122 of the weight reduction mechanism 12 before the first guide plate 21, so that the ointment tube moves to the bottom of the material preparation box 10 in an orderly manner;

[0074] A guide plate 281 is formed at the bottom of the second guide plate 28, and the guide plate 281 is parallel to the upper surface of the bottom frame 1; a material outlet 11 of the material preparation box 10 is formed between the guide plate 281 and the upper surface of the bottom frame 1;

[0075] The distance between the guide plate 281 and the upper surface of the bottom frame 1 is greater than one times the diameter of the ointment tube and less than two times the diameter of the ointment tube, so that only one of the ointment tubes in the preparation box 10 can be discharged from the discharge port 11;

[0076] The other end of the second support plate 27 is fixedly connected to the drive shaft 29, and the drive shaft 29 is movably arranged through the side wall of the material preparation box 10;

[0077] The fixed bracket 14 is located above the driving shaft 29; when the ointment tube in the preparation box 10 moves downward under its own weight, it first reaches the first guide plate 21 connected to the fixed bracket 14, and then reaches the second guide plate 28 connected to the first guide plate 21.

[0078] The working principle of the discharge port dredging mechanism is as follows:

[0079] During installation, the driving shaft 29 is rotated to determine the initial angle of the second supporting plate 27, thereby determining the initial tilt angle of the second guiding plate 28;

[0080] Loosen the axle of the roller 25 and move the second adjustment block 26 along the second guide groove of the second support plate 27 to adjust the initial position of the roller 25 and the guide rail 24; then tighten the axle of the roller 25 to fix the second adjustment block 26 to the second support plate 27;

[0081] The first adjusting block 23 is loosened, and the first adjusting block 23 can be moved along the first guide groove of the first supporting plate 22 to adjust the initial position of the first adjusting block 23, thereby adjusting the initial inclination angle of the first guiding plate 21; the initial inclination angle of the second guiding plate 28 is made smaller than the initial inclination angle of the first guiding plate 21; and then the first adjusting block 23 is tightened to fix the first adjusting block 23 to the first supporting plate 22;

[0082] The swing of the driving shaft 29 can drive the second guide plate 28 and the second support plate 27 to swing synchronously;

[0083] During the swinging process of the second support plate 27, the second support plate 27 drives the roller 25 to move along the guide groove at the lower edge of the guide rail 24 through the second adjustment block 26, thereby driving the guide rail 24 to swing; the guide rail 24 drives the first support plate 22 and the first guide plate 21 to swing around the pin shaft 15 through the first adjustment block 23;

[0084] During the swinging of the first guiding plate 21, the first guiding plate 21 can move the ointment tubes moving above it in a direction away from the discharge port 11, thereby preventing the ointment tubes from piling up near the discharge port 11; and the ointment tubes moving below the first guiding plate 21 continue to move toward the discharge port 11;

[0085] During the swinging process of the second guiding plate 28, the second guiding plate 28 can push the ointment tubes moving to the discharge port 11 in a direction away from the discharge port 11; since the distance between the guide plate 281 of the second guiding plate 28 and the upper surface of the bottom frame 1 is greater than the diameter of the ointment tubes, the ointment tubes at the bottom layer cannot contact the second guiding plate 28, and thus can be discharged from the discharge port 11 in sequence along their original path, thereby forming a single-layer queue behind the discharge port 11;

[0086] The present invention only requires an external power source to enable the first guide plate and the second guide plate to swing synchronously, thereby guiding the ointment tubes stacked in the material preparation box at different positions, so that the stacked ointment tubes automatically form a single-layer queue, preparing for subsequent continuous automatic production.

[0087] like Fig. 9 As shown, a power drive mechanism is arranged outside the material preparation box 10; the power drive mechanism comprises an eccentric wheel 34, the axle of the eccentric wheel 34 is fixedly connected to an external power source, and the external power source can drive the eccentric wheel 34 to rotate around its rotation center; the eccentric wheel 34 is movably connected to the lower end of the first connecting rod 33 through a lower end pin shaft 322; a radial spacing is formed between the lower end pin shaft 322 and the axle of the eccentric wheel 34, so that the lower end of the first connecting rod 33 deviates from the rotation center of the eccentric wheel 34;

[0088] The upper end of the first connecting rod 33 is movably connected to the lower end of the second connecting rod 32 through the upper end pin shaft 331, and the upper end of the second connecting rod 32 is movably connected to the third connecting rod 31; the upper end pin shaft 331 is fixedly connected to the driving block 6 of the ointment tube pushing mechanism;

[0089] A connecting rod guide groove 311 is formed on the third connecting rod 31; a slider 321 is provided at the upper end of the second connecting rod 32; the slider 321 is disposed in the connecting rod guide groove 311 of the third connecting rod 31;

[0090] The fixed end of the third connecting rod 31 is fixedly connected to the driving shaft 29 of the discharge port guiding mechanism; the driving shaft 29 passes through the rear side wall of the material preparation box 10 .

[0091] The power drive mechanism of the present invention only needs an external power source to realize the reciprocating motion of the drive block 6 and the swing of the drive shaft 29 .

[0092] The working principle of the present invention is as follows:

[0093] The external power source is driven to drive the eccentric wheel 34 to rotate around its rotation center, thereby driving the lower end of the first connecting rod 33 to rotate around the rotation center of the eccentric wheel 34;

[0094] Since the movement of the driving block 6 fixedly connected to the upper pin shaft 331 is constrained by the slide bar 2, the upper pin shaft 331 and the driving block 6 can only move along the length direction of the slide bar 2; therefore, the circumferential movement of the lower end of the first connecting rod 33 can drive the upper end of the first connecting rod 33 to reciprocate;

[0095] The upper end of the first connecting rod 33 drives the lower end of the second connecting rod 32 to reciprocate through the upper end pin 331, thereby driving the third connecting rod 31 and the driving shaft 29 to swing at a small angle around the rotation center of the driving shaft 29; Fig. 9The two extreme positions of the third connecting rod 31 are shown in FIG. 1 ; the solid line is the lowest point of the third connecting rod 31 , and the dotted line is the highest point of the third connecting rod 31 ; the swing amplitude of the drive shaft 29 is determined by the position of the slider 321 in the connecting rod guide groove 311 of the third connecting rod 31 ;

[0096] The ointment tubes are put into the preparation box 10, and the total height of the ointment tubes piled in the preparation box 10 can exceed the position of the weight reduction mechanism 12; the ointment tubes first reach the height of the weight reduction mechanism 12 under their own weight, then reach the height of the first guide plate 21, and finally reach the height of the second guide plate 28;

[0097] The driving block 6 drives the lower slider 4 fixedly connected thereto to reciprocate along the slide bar 2, and the lower slider 4 drives the movable plate 5 to reciprocate relative to the base frame 1; at the same time, the other lower slider 4 and the two upper sliders 3 move synchronously along the slide bar 2, thereby guiding the movement of the movable plate 5;

[0098] When the movable plate 5 reciprocates along the inclined direction at the bottom of the material preparation box 10 relative to the bottom frame 1, the plurality of ointment tubes in the material preparation box 10 are driven to reciprocate along the inclined direction;

[0099] The swing of the driving shaft 29 drives the second guide plate 28 and the second support plate 27 to swing synchronously; during the swinging process of the second support plate 27, the second support plate 27 drives the roller 25 to move along the guide groove at the lower edge of the guide rail 24, thereby driving the guide rail 24 to swing; the guide rail 24 drives the first support plate 22 and the first guide plate 21 to swing around the pin shaft 15;

[0100] When the ointment tube reaches the weight-reducing mechanism 12, the weight-reducing mechanism 12 guides the ointment tube to the first guiding plate 21 through its guide plate 122; the first guiding plate 21 can buffer the fall of the ointment tube and make the ointment tube that arrives first slide downward along the inclined surface of the first guiding plate 21 to the bottom of the first guiding plate 21;

[0101] During the swinging process, the first guide plate 21 moves the ointment tube above it away from the discharge port 11, while the ointment tube below it continues to move downward to the movable plate 5 and the bottom frame 1 at the bottom of the preparation box 10; through the reciprocating motion of the movable plate 5, the ointment tube intermittently obtains a driving force toward the discharge port 11, and the driving force is superimposed on the own gravity of the ointment tube, so that the ointment tube has a movement tendency toward the discharge port 11;

[0102] When the ointment tube moves toward the discharge port 11 to the second guide plate 28, the second guide plate 28 pushes the ointment tube in contact with it away from the discharge port 11 during the swinging process; only the ointment tubes at the bottom of the preparation box 10 move in an orderly manner along their original path toward the discharge port 11, and are ejected from the discharge port 11 in turn, thereby forming a single-layer queue behind the discharge port 11 to prepare for feeding for the next process.

[0103] The present invention only needs an external power source to drive the movable plate of the ointment tube pushing mechanism to reciprocate, and at the same time drive the first guide plate and the second guide plate to swing synchronously; the ointment tube pushing mechanism can cause the ointment tubes at the bottom of the preparation box to move toward the discharge port, and the first guide plate and the second guide plate can enable the ointment tubes at the bottom to be spit out from the discharge port in sequence to form a single-layer queue. Therefore, the present invention can help to significantly improve the production efficiency of ointment medicines.

[0104] The method for automatically forming a single-layer queue of ointment tube stacks according to the present invention comprises the following steps:

[0105] The first step is to drive the external power source to rotate the eccentric wheel 34 around its rotation center, thereby driving the driving block 6 to reciprocate and drive the driving shaft 29 to swing;

[0106] In the second step, the driving block 6 drives the movable plate 5 to reciprocate relative to the base frame 1; the swing of the driving shaft 29 drives the second guide plate 28 and the first guide plate 21 to swing synchronously;

[0107] In the third step, the ointment tubes accumulated in the preparation box 10 move downward from top to bottom; when the ointment tubes reach the weight reduction mechanism 12, the weight reduction mechanism 12 guides the ointment tubes to the first guide plate 21 through its guide plate 122; the ointment tubes that arrive first slide downward along the inclined surface of the first guide plate 21 to the bottom of the first guide plate 21, and the ointment tubes that arrive later are accumulated above the first guide plate 21;

[0108] In the fourth step, the first guiding plate 21 moves the ointment tube above it away from the discharge port 11 during the swinging process to prevent the ointment tube from piling up near the discharge port 11; the ointment tube below the first guiding plate 21 continues to move downward to the movable plate 5 and the bottom frame 1 at the bottom of the preparation box 10; the reciprocating motion of the movable plate 5 enables the ointment tube to intermittently obtain a driving force toward the discharge port 11, and the driving force is superimposed on the self-weight of the ointment tube, so that the ointment tube has a movement tendency toward the discharge port 11;

[0109] In the fifth step, the ointment tubes under the first guide plate 21 move toward the discharge port 11 to the second guide plate 28, and the second guide plate 28 pushes the ointment tubes in contact with it away from the discharge port 11 during the swinging process; the ointment tubes at the bottom of the preparation box 10 move orderly and step by step toward the discharge port 11 along their original path, and are spit out from the discharge port 11 in turn, thereby forming a single-layer queue behind the discharge port 11.

[0110] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these changes and modifications.
