Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical machinery, and in particular to a push-bottle structure for large-volume infusion plastic bottles. Background Technology

[0002] Currently, the production of large-volume parenteral solutions typically uses polypropylene (PP) plastic bottles. These bottles undergo high-temperature sterilization after filling and are then transported via sterilization carts. In existing technology, a specially designed conveyor belt with partitions transports the filled bottles in rows, maintaining an upright posture, to the bottle loading machine. The bottle loading machine is the key equipment for transferring the bottles from the conveyor belt to downstream stations such as the sterilization cart; its core component is the bottle pushing mechanism. After the first-stage bottle pushing mechanism pushes the bottles from the conveyor belt into the bottle loading channel, the second-stage mechanism pushes the bottles from the channel to the downstream station on the production line.

[0003] As attached Figure 1-2 Taking the bottle-pushing structure shown as an example, the bottle-pushing mechanism 1 includes a limiting track 11, a traveling module 12, a connecting plate 13, and a pusher plate 14. The traveling module 12 is used to drive the connecting plate 13 and the pusher plate 14 to reciprocate along the limiting track 11, and the pusher plate 14 is used to push the plastic bottles 3 in the upper bottle channel 2. There are five plastic bottles 3 in each row in the upper bottle channel 2. Before the bottle-pushing mechanism 1 starts pushing the plastic bottles 3 in the upper bottle channel 2, guard plates 21 are raised on both sides of the upper bottle channel 2 in the length direction. The distance between the two guard plates 21 is slightly greater than the sum of the widths of the five plastic bottles 3 in each row. The traveling module 12 drives the pusher plate 14 to move through the connecting plate 13, thereby pushing all the plastic bottles 3 in the upper bottle channel 2 in rows to the next station.

[0004] In the aforementioned process, the pusher plate 14 in the bottle pushing mechanism 1 widely uses a flat type, and the plastic bottles 3 in the same row move synchronously under the action of the pusher plate 14. However, if the resistance of foreign particles suddenly increases at a certain point in the bottle upper channel 2, or if there is a slight deviation in the docking position of the downstream receiving device, the rows of plastic bottles 3 are prone to tipping over due to instability of the center of gravity. Moreover, the plastic bottles 3 on both sides of the same row are prone to friction with the guard plate 21, resulting in scratches, whitening, and other problems on the plastic bottles 3, causing irreversible damage to the appearance of the product and significantly increasing the defect rate. In addition, the rigid connection structure between the connecting plate 13 and the pusher plate 14 also results in a lack of buffering mechanism in the bottle pushing process. When the pushing resistance suddenly increases at a certain point, it cannot be adjusted in time, which can easily lead to accidents such as the plastic bottles 3 being squeezed and bursting or the equipment jamming. Therefore, it is necessary to improve the existing bottle pushing structure. Utility Model Content

[0005] To address the problems existing in the prior art, where flat push plates are prone to tipping over when pushing rows of plastic bottles, and where bottles on both sides of the same row are prone to friction with the protective plate, resulting in scratches and whitening, this utility model aims to provide a large-volume infusion bottle pushing structure. By adding a protruding arc-shaped part to the side of the push plate facing the plastic bottle, the outer contour line of the same row of plastic bottles changes from a straight line to an arc shape, shortening the sum of the widths of each row of plastic bottles, thereby increasing the distance between the edge of the plastic bottle and the protective plate. Moreover, the bottles in the same row are pushed one after another, reducing the probability of tipping over.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A large-volume infusion bottle pushing structure includes a pushing mechanism and an upper bottle channel. The pushing mechanism is used to push a row of plastic bottles located in the upper bottle channel. The pushing mechanism includes a limiting track, a traveling module, a connecting plate, and a push plate. The traveling module drives the connecting plate to reciprocate along the limiting track. The push plate is installed below the connecting plate and is used to push the plastic bottles in the upper bottle channel. The pushing mechanism also includes an arc-shaped part. The height of the arc-shaped part is equal to the height of the push plate, and the arc-shaped part completely covers the side of the push plate facing the plastic bottle. On the horizontal plane, the middle part of the arc-shaped part protrudes in the pushing direction of the push plate.

[0007] The present invention is further configured such that the circumferential angle corresponding to the arc on the arc-shaped part on the horizontal plane is 60-90 degrees.

[0008] The present invention is further configured such that: the bottle pushing mechanism further includes a pad layer, the pad layer is fixed on the contact surface between the arc-shaped portion and the plastic bottle, and the pad layer is made of an elastic material.

[0009] The present invention is further configured such that the pad is made of silicone or rubber.

[0010] The present invention is further configured to include a swing mechanism, the swing mechanism comprising a swing rod and a hinge shaft, one end of the swing rod being fixed to a connecting plate and the other end extending toward a push plate, the push plate having a gap with the connecting plate; the hinge shaft being fixed to the push plate and passing vertically through the end of the swing rod, the swing rod and the push plate being hinged together by the hinge shaft.

[0011] The present invention is further configured such that the axis of the hinge shaft on the horizontal plane is located at the middle position in the length direction of the push plate.

[0012] The present invention is further configured to include a buffer mechanism, wherein the buffer mechanism includes a spring, the spring is installed and fixed between the push plate and the connecting plate and there is a gap between the push plate and the connecting plate.

[0013] The present invention is further configured to include a buffer mechanism, wherein the buffer mechanism includes a spring, the spring is installed and fixed between the push plate and the connecting plate, and the spring is located on both sides of the swing rod on the horizontal plane.

[0014] The present invention is further configured such that springs are provided above and below the swing rod in the vertical direction.

[0015] This invention is further configured such that springs with different elastic forces can be replaced at all locations where the springs are installed.

[0016] In summary, the beneficial effects achieved by this utility model are as follows: (1) The arc-shaped part changes the outer contour of the plastic bottles in the same row from a straight line to an arc, shortening the sum of the widths of each row of plastic bottles, thereby increasing the distance between the edge of the plastic bottle and the guard plate; and, in the same row of plastic bottles, the plastic bottle in the central position is pushed first and the plastic bottles on both sides are pushed later, which not only avoids the plastic bottles in the same row from affecting each other, but also the plastic bottle in the central position can provide a certain support for the plastic bottles on both sides, thereby reducing the probability of bottles tipping over. (2) The padding layer can prevent the hard curved part from directly contacting the plastic bottle and causing scratches and wear on the plastic bottle surface. At the same time, it can reduce the local stress and compression of the plastic bottle to a certain extent through elasticity. (3) The swing mechanism changes the connection between the connecting plate and the push plate from a fixed connection to a hinge. The push plate and the arc part can swing within a certain range, so that the contact angle with the plastic bottle can be adaptively adjusted according to the resistance encountered during the bottle pushing process. (4) The buffer mechanism enables the push plate and the arc-shaped part to play a buffering role when they suddenly encounter large resistance during the bottle pushing process. Combined with the swing mechanism, it further enhances the adaptive internal ability of the push plate and the arc-shaped part to sudden resistance during the bottle pushing process, ensuring the smooth pushing of the plastic bottle.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] It should be noted that the embodiments and features involved in the embodiments of this utility model can be combined with each other without conflict. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0022] As attached Figure 3-6 As shown, a large-volume infusion plastic bottle pusher structure includes a pusher mechanism 1, an upper bottle channel 2, a buffer mechanism 4, and a swing mechanism 5.

[0023] The bottle-pushing mechanism 1 is used to push the rows of plastic bottles 3 located in the upper bottle channel 2. The plastic bottles 3 contain liquid medicine. In this embodiment, there are 5 plastic bottles 3 in each row.

[0024] Both sides of the bottle-feeding channel 2 are provided with protective plates 21. The height of the protective plates 21 is slightly lower than the height of the plastic bottles 3, and the distance between the two protective plates 21 is slightly greater than the sum of the widths of the five plastic bottles 3 in each row. The protective plates 21 can prevent the plastic bottles 3 from slipping out of the bottle-feeding channel 2 during the pushing process.

[0025] The bottle pushing mechanism 1 includes a limiting track 11, a traveling module 12, a connecting plate 13, a push plate 14, an arc-shaped part 15, and a pad layer 16.

[0026] The limiting track 11 and the traveling module 12 are both existing technologies. Together, they enable the connecting plate 13 to reciprocate along the length of the upper bottle channel 2. The top end of the connecting plate 13 is fixed to the traveling module 12, and the bottom end of the connecting plate 13 is fixedly connected to the push plate 14.

[0027] The push plate 14 is a flat plate structure located in the upper bottle channel 2, and is used to push the plastic bottle 3 under the drive of the connecting plate 13.

[0028] One side of the arc-shaped portion 15 is flat and the other side is curved. The flat side of the arc-shaped portion 15 is fitted and fixed to the push plate 14. The height and dimensions of the arc-shaped portion 15 in each direction are adapted to the push plate 14, so the arc-shaped portion 15 can completely cover the side of the push plate 14 facing the plastic bottle 3.

[0029] In the horizontal cross section, the middle part of the arc-shaped portion 15 protrudes in the pushing direction of the push plate 14 to form an arc-shaped protrusion, and the size range of the circumferential angle corresponding to the arc is 60-90 degrees.

[0030] The padding layer 16 has a uniform thickness and is made of an elastic material, covering and fixing it to the contact surface between the curved portion 15 and the plastic bottle 3. In this invention, the padding layer 16 can be made of rubber or food-grade silicone.

[0031] The swing mechanism 5 is used to realize the hinge between the connecting plate 13 and the push plate 14. Specifically, the swing mechanism 5 includes a swing rod 51 and a hinge shaft 52.

[0032] The swing rod 51 is a horizontally arranged rectangular column structure, with one end fixed to the connecting plate 13 and the other end extending toward the push plate 14.

[0033] Both ends of the hinge shaft 52 are fixed on the push plate 14 and the hinge shaft 52 passes vertically through the end of the swing rod 51 away from the connecting plate 13, so that the swing rod 51 and the push plate 14 are hinged through the hinge shaft 52.

[0034] Because of the length of the swing rod 51, there is a certain gap between the push plate 14 and the connecting plate 13, so the push plate 14 can swing left and right relative to the connecting plate 13 around the axis of the hinge shaft 52 within a certain angle range.

[0035] The swing arm 51 is located at the center of the push plate 14, that is, in the horizontal cross section, the axis of the hinge shaft 52 is located at the middle position in the length direction of the push plate 14.

[0036] The buffer mechanism 4 includes a mounting groove 41, a spring 42, and a fixing bolt 43.

[0037] Mounting slot 41 is a blind hole opened on push plate 14, horizontally set, for accommodating spring 42.

[0038] The connecting plate 13 also has a through hole for the spring 42 to pass through, and the fixing bolt 43 can be threaded into the inner wall of the through hole. After the spring 42 passes through the through hole and enters the mounting groove 41, the spring 42 can be pressed and fixed between the connecting plate 13 and the push plate 14 by tightening the fixing bolt 43.

[0039] Furthermore, springs 42 are provided on both sides of the swing shaft in the horizontal cross-section. As a result, the push plate 14 and the arc-shaped part 15 can not only swing within a certain angle range, but also be subjected to the elastic force of the springs 42 during the swing process, thereby exerting the buffering effect of the springs. This allows the push plate 14 and the arc-shaped part 15 to buffer the sudden increase in resistance during the bottle pushing process and adaptively adjust the contact angle with the plastic bottle 3 according to the resistance received.

[0040] Since the push plate 14 has a certain height, springs 42 are provided above and below the swing rod 51 in the vertical direction to stably exert the buffering effect of the springs 42. In particular, the springs 42 in all mounting slots 41 can be replaced with springs 42 with different elastic forces, so that the bottle pushing mechanism 1 can widely adapt to different pushing resistances.

[0041] In some other embodiments, the two ends of the spring 42 can be directly fixed between the push plate 14 and the connecting plate 13 without setting the swing mechanism 5, so that the bottle pushing mechanism 1 can adaptively adjust the pushing resistance by relying solely on the cooperation of the compression or stretching of the spring 42 at different positions.

[0042] The implementation principle of the above embodiments is as follows: When rows of plastic bottles 3 enter the upper bottle channel 2, the guard plates 21 on both sides of the upper bottle channel 2 rise, and the walking module 12 begins to move, driving the push plate 14 and the arc-shaped part 15 to move along the upper bottle channel 2 via the connecting plate 13. After the padding layer 16 around the arc-shaped part 15 contacts the plastic bottle 3, the plastic bottle 3 located in the center of the same row is pushed first, followed by the plastic bottles 3 located on both sides, reducing the probability of bottle tipping. Moreover, during the pushing process, if the pushing resistance suddenly increases at a certain point, the push plate 14 and the arc-shaped part 15 can adjust the contact angle with the plastic bottle 3 in time according to the pushing resistance through the swing mechanism 5 and the buffer mechanism 4, thereby making adaptive adjustments to prevent the plastic bottle 3 from being crushed or the equipment from jamming, ensuring the smooth pushing of the plastic bottle 3.

[0043] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if such modifications and modifications fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include such modifications and modifications.
