Description

Technical Field

[0001] This utility model relates to the field of bag-making machine technology, specifically a bag-making machine that adapts to multiple bag sizes. Background Technology

[0002] The adaptive multi-specification bag ejector is a device that can automatically eject bags of different specifications and sizes. Through intelligent recognition and adjustment technology, it can automatically adapt to bags of different sizes and materials, effectively solving the problems of single specifications and cumbersome replacement of traditional bag ejectors.

[0003] Adaptive multi-size bag dispensers used in hospitals can dispense hundreds of bags per day due to scenarios such as daily medication dispensing in pharmacies, specimen transfer in laboratories, and item distribution at nurses' stations. Manual bag dispensing is time-consuming and tiring. The application of adaptive multi-size bag dispensers in hospitals reduces manual intervention, improves efficiency, and reduces medical risks by accurately adapting to different sizes.

[0004] After obtaining the medication, the person holding the prescription and the medication (such as boxed medicine or bottled liquid) in one hand needs to quickly grab the bag with the other hand to pack the medication into a bag. An angle deviation when grabbing the bag with one hand will cause uneven force distribution when pulling the bag, resulting in wrinkles and folds in the bag due to pulling. The bag dispensing machine sensor may mistakenly identify "bag already taken", leading to bag stacking and jamming malfunctions when picking up bags later.

[0005] Therefore, an adaptive bag-dispensing machine for multiple bag sizes is proposed to address the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an adaptive bag-dispensing machine for multiple bag sizes to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An adaptive multi-size bag ejector includes an ejector and an ejector structure suitable for multi-size bags. An advertising door is rotatably connected to one side of the ejector, and a clamping device is fixedly connected to one side of the advertising door. The clamping device includes a fixed frame with an operating opening on its inner side, a sliding groove on the inner upper end of the fixed frame, a slot on the bottom inner side of the fixed frame, a friction groove at the bottom of the slot, a limit groove on the outer side of the fixed frame, and a handle rotatably connected to the outer side of the fixed frame. A limit block is fixedly connected to the outer side of the handle. A gear is fixedly connected to one end of the handle, passing through one side of the fixed frame, and a clamping plate is meshed with the outer side of the gear. The clamping plate includes a plate body with a toothed plate fixedly connected to one side of the plate body, damping plates fixedly connected to the bottom of both ends of the plate body, and a locking post fixedly connected to the lower end of the damping plate.

[0009] As a further optimization of this utility model, the following features are provided: an installation support plate for installing roll bags is fixedly connected to the inner side of the bag-eating machine by bolts; a bag-eating structure is fixedly connected to the side of the bag-eating machine near the bag-eating opening; and the outlet of the bag-eating structure corresponds to the outlet position of the bag-eating opening.

[0010] As a further optimization of this utility model, the length of the operating port is adapted to the length corresponding to the inner side of the bag outlet, the outlet end of the bag outlet is directly opposite the inlet end of the operating port, one side of the limiting block is slidably connected to the inner side of the limiting groove, and the limiting groove is semi-circular in shape.

[0011] As a further optimization of this utility model, the slide groove is a rectangular groove, the width of the slide groove is consistent with the width of the adapter structure at both ends of the clamping plate, and the inner side of the slide groove is slidably connected to the outer side of the clamping plate.

[0012] As a further optimization of this utility model, the following features are provided: the card slot is a rectangular groove, the width of the card slot is adapted to the card post at the bottom of the clamping plate, the card slot is connected to the friction groove and the sliding groove, and the outer sides of both ends of the clamping plate are engaged with the inner side of the card slot.

[0013] As a further optimization of this utility model, the inner side of the friction groove and the outer side of the locking post are in contact with each other, the number of friction grooves and locking posts are corresponding, and the inner side of the friction groove and the locking post are staggered.

[0014] As a further optimization of this utility model, the toothed plate is elongated, the tooth profile of the toothed plate is adapted to the tooth profile of the gear, the toothed plate is perpendicular to one side of the plate body, and the toothed plate is meshed with the outer side of the gear.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the clamping device, by rotating the handle, drives the gear to rotate. Because the gear meshes with the toothed plate, it drives the clamping plate to slide along the inner side of the fixed frame. At the same time, it can make the two ends of the bag alternately fit with the friction groove and the locking post. As the toothed plate and the gear mesh and lock, the stability of the clamping state is further enhanced, ensuring that the bag is firmly clamped. This makes it convenient for the operator to pick up and use the bag with one hand, and ensures that the subsequent bag retrieval is normal. The limiting block slides along the semi-circular limiting groove, which can effectively limit the rotation angle and ensure stable guidance. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figures 1-6 This utility model provides a technical solution:

[0029] An adaptive multi-size bag ejector includes an ejector 1 and an ejector structure 5 suitable for multi-size bags. An advertising door 2 is rotatably connected to one side of the ejector 1, and a clamping device 6 is fixedly connected to one side of the advertising door 2. The clamping device 6 includes a fixed frame 61, an operating opening 62 on the inner side of the fixed frame 61, a sliding groove 63 on the inner side of the upper end of the fixed frame 61, a slot 64 on the bottom inner side of the fixed frame 61, a friction groove 65 at the bottom of the slot 64, and a limit position on the outer side of the fixed frame 61. A handle 67 is rotatably connected to the outside of the slot 66 and the fixing frame 61. A limit block 68 is fixedly connected to the outside of the handle 67. A gear 69 is fixedly connected to one side of the fixing frame 61 through one end of the handle 67. A clamping plate 610 is meshed with the outside of the gear 69. The clamping plate 610 includes a plate body 6101. A toothed plate 6102 is fixedly connected to one side of the plate body 6101. Damping plates 6103 are fixedly connected to the bottom of both ends of the plate body 6101. A locking post 6104 is fixedly connected to the lower end of the damping plate 6103.

[0030] It should be noted that: the inner side of the bag-eating machine 1 is fixedly connected with a mounting support plate 4 for installing the roll bag by bolts, and the bag-eating machine 1 is fixedly connected with a bag-eating structure 5 near the bag-eating port 3. The outlet of the bag-eating structure 5 corresponds to the outlet position of the bag-eating port 3. The length of the operating port 62 is adapted to the corresponding length inside the bag-eating port 3. The outlet end of the bag-eating port 3 is directly opposite the inlet end of the operating port 62. The limiting block 68 is slidably connected to the inner side of the limiting groove 66. The limiting groove 66 is semi-circular in shape.

[0031] Furthermore, the gear 69 and toothed plate 6102 are used to drive the clamping plate 610 to firmly hold the bag, so that the bag is not easy to shift or fall off during the process of the operator picking up and operating the bag, thus ensuring the stability of manual bag removal after the bag is dispensed.

[0032] Specifically: the length of the operating port 62 is adapted to the length of the bag outlet 3, and the outlet end and the inlet end are aligned, accurately connecting the bag outlet and subsequent operation links. The semi-circular ring-shaped limiting groove 66, together with the limiting block 68, not only limits the rotation range of the handle 67 to avoid damage to the equipment due to misoperation, but also provides stable guidance for clamping adjustment, ensuring that the clamping action is controllable and precise. The whole system ensures that the operation links such as roll bag installation, bag delivery, clamping and picking do not interfere with each other. From the source of bag material to the end use, a stable and reliable bag delivery system is built, reducing the risk of loss of control due to structural misalignment.

[0033] As a further implementation of this scheme, the toothed plate 6102 is elongated, and the tooth profile of the toothed plate 6102 is adapted to the tooth profile of the gear 69. The toothed plate 6102 is perpendicular to one side of the plate body 6101, and the toothed plate 6102 is meshed with the outer side of the gear 69.

[0034] It should be noted that: the slide groove 63 is a rectangular groove, and the width of the slide groove 63 is consistent with the width of the adapting structure at both ends of the clamping plate 610. The inner side of the slide groove 63 is slidably connected to the outer side of the clamping plate 610. The slot 64 is a rectangular groove, and the width of the slot 64 is adapted to the slot post 6104 at the bottom of the clamping plate 610. The slot 64 is connected to the friction groove 65 and the slide groove 63. The outer sides of both ends of the clamping plate 610 are engaged with the inner side of the slot 64. The inner side of the friction groove 65 and the outer side of the slot post 6104 are in contact with each other. The number of friction grooves 65 and slot posts 6104 are corresponding, and the inner side of the friction groove 65 and the slot post 6104 are staggered.

[0035] Furthermore, the elongated toothed plate 6102 and the gear 69 are matched in tooth shape and vertically connected to form a stable meshing transmission pair. When the handle 67 is turned, the gear 69 can precisely drive the toothed plate 6102, causing the clamping plate 610 to move linearly and squeeze both ends of the bag, so that both ends of the bag enter the slide groove 63. The friction groove 65 and the locking post 6104 are interlocked and fitted. At the same time, the meshing and locking of the toothed plate 6102 and the gear 69 further enhances the stability of the clamping state, ensures that the bag is firmly clamped, and facilitates one-handed operation by the operator.

[0036] Specifically: the slide groove 63 restricts the horizontal displacement of the clamping plate 610, and the slot 64 and the locking post 6104 restrict vertical swaying, so that the clamping plate 610 slides smoothly without deviation, improving the stability and reliability of clamping adjustment. The friction groove 65 and the locking post 6104 are staggered and fit together to increase contact damping. Together with the locking limit of the slot 64, the clamping plate 610 is not easy to be displaced by the pulling force of bag removal after it is adjusted to the right position.

[0037] Workflow: The central shaft of the roll bag is bolted to the mounting support plate 4 inside the bag ejector 1. The roll bag unfolding direction corresponds to the conveying path of the bag ejection structure 5 and the operating port 62, ensuring that the bag material can smoothly enter the bag ejection structure 5. After the bag ejector 1 is started, the internal power mechanism drives the bag ejection structure 5 to operate. The roll bag is gradually released from the mounting support plate 4. Through the transmission system of the bag ejector 1, the bag is sorted and conveyed by the bag ejection structure 5, and then conveyed to the operating port 62 in sequence. The bag enters the clamping device 6 through the outlet of the bag ejection structure 5, facing the inlet end of the operating port 62.

[0038] First, a space is reserved between the clamping plate 610 and the operating port 62 to accommodate the passage of bags. When the operator needs to pick up the bag with one hand, the handle 67 is turned. The handle 67 drives the gear 69 to rotate. Since the gear 69 meshes with the toothed plate 6102, when the gear 69 rotates, the toothed plate 6102 drives the clamping plate 610 to slide along the inner side of the fixed frame 61. During the rotation of the handle 67, the limiting block 68 slides along the semi-circular limiting groove 66, limiting the rotation angle of the handle 67. At the same time, the damping plates 6103 at both ends of the clamping plate 610 move downward with the plate body 6101, and the locking post 6104 slides in the locking groove 64. The friction groove 65 is continuously in contact with the outer side of the locking post 6104, so as to continuously and firmly clamp the two ends of the two bags, making it easy for the operator to tear open the bags with one hand for use. After use, the handle 67 is turned in the opposite direction to reset the clamping plate 610 to the initial position, so that the next bag can pass through and the operation can continue.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
