Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and in particular to a roller bag-feeding mechanism and an automatic packaging device. Background Technology

[0002] A bag-removing mechanism is a device used to extract garbage bags folded and stored inside a garbage bin for use. It is commonly used in products such as automatic baling garbage bins and automatic baling pet litter boxes (such as cat litter boxes). This mechanism extracts only one section of the garbage bag at a time by performing a specific bag-removing action, thus meeting the user's need for continuous and convenient garbage bag replacement.

[0003] Currently, the most common method for garbage bag removal is a push-rod structure. This involves a drive mechanism that controls a push rod to push the garbage bag downwards, forcing it to detach from the container. This design requires the push rod and its drive mechanism to be positioned directly above the garbage container, undoubtedly occupying top space and resulting in a complex and inefficient overall structure. This severely limits its applicability for products where the top needs to be open or where space is limited. In practical applications, this method is prone to uneven bag removal due to uneven force distribution, leading to asynchronous and uneven bag exit from different sides, affecting the success rate and reliability of the removal process.

[0004] In addition, there is a bag-feeding method that utilizes negative pressure adsorption, but this method generates significant operating noise in actual use, resulting in a poor user experience. Furthermore, its bag-feeding process is susceptible to interference from factors such as sealing performance and bag material, exhibiting insufficient operational stability and reliability. Therefore, there is an urgent need in this field for a novel bag-feeding mechanism that is simpler in structure, more widely applicable, and more stable and reliable in operation. Utility Model Content

[0005] The technical problem to be solved by this utility model is the complexity of the traditional push-rod type bag lowering mechanism.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a roller bag-feeding mechanism, comprising:

[0007] Garbage bag holders are used to store folded garbage bags;

[0008] A base for holding the garbage bag container;

[0009] At least one lower bag drive wheel is mounted on the bag box base;

[0010] At least one driven wheel for the lower bag is mounted on the garbage bag container and abuts against the driving wheel for the lower bag;

[0011] A drive mechanism is used to drive the lower bag drive wheel to rotate;

[0012] When the garbage bag box is placed on the base of the bag box, the garbage bag passes between the lower bag drive wheel and the lower bag driven wheel, and the garbage bag is pulled out of the garbage bag box by the rotation of the lower bag drive wheel.

[0013] Furthermore, the garbage bag box has a ring-shaped quadrilateral structure; there are four driving wheels and four driven wheels for the lower bag, forming four pairs of transmission pairs; the four pairs of transmission pairs are respectively located on the four sides of the ring-shaped quadrilateral garbage bag box; the driving mechanism synchronously drives the four driving wheels for the lower bag to rotate, so that the garbage bag is evenly discharged from all four sides.

[0014] Furthermore, the drive mechanism includes a drive motor, a worm gear assembly driven by the drive motor, and a drive link connected to the output end of the worm gear assembly; there are four drive links, and the four lower bag drive wheels are respectively fixedly mounted on the four drive links, and the four drive links are sequentially meshed and driven by a helical gear set provided thereon.

[0015] Furthermore, the lower bag drive wheel is a gear; the lower bag driven wheel is a gear that can mesh with the lower bag drive wheel.

[0016] Furthermore, both the lower bag drive wheel and the lower bag driven wheel are friction wheels with flat surfaces, which are driven to move by the friction generated by clamping the garbage bag.

[0017] Furthermore, the four pairs of transmission pairs are respectively located at the middle positions of the four sides of the annular quadrilateral garbage bag box.

[0018] Furthermore, the garbage bag container is detachably mounted on the bag container base.

[0019] Furthermore, the drive mechanism also includes a control unit for controlling the number of rotations of the lower bag drive wheel to precisely control the length of the lower bag.

[0020] Furthermore, the base of the garbage bag is equipped with a detection sensor for detecting whether the garbage bag is installed in place.

[0021] The present invention also provides an automatic packaging device, including a roller bag-discharging mechanism as described in any of the preceding claims, for extracting garbage bags from a garbage bag container.

[0022] The beneficial effects of this invention are as follows: It provides a completely new, more stable and reliable bag-loading method, replacing the traditional push-rod or negative pressure suction method. This structure fundamentally avoids the overhead space required by the push-rod mechanism, making the overall layout more flexible and suitable for products with limited top space. At the same time, the wheel-type rotating bag-loading action is smoother and gentler, overcoming the shortcomings of the negative pressure method, such as high noise and easy failure.

[0031] like Figures 1 to 4As shown, an embodiment of this utility model is: a roller bag-feeding mechanism, comprising:

[0032] Garbage bag box 1, for storing folded garbage bags 6;

[0033] The garbage bag base 2 is used to hold the garbage bag box 1.

[0034] At least one lower bag drive wheel 3 is mounted on the bag box base 2;

[0035] At least one lower bag driven wheel 4 is installed on the garbage bag box 1 and abuts against the lower bag driving wheel 3;

[0036] Drive mechanism 5 is used to drive the lower bag drive wheel 3 to rotate;

[0037] When the garbage bag box 1 is placed on the bag box base 2, the garbage bag 6 passes between the lower bag drive wheel 3 and the lower bag driven wheel 4, and the garbage bag 6 is pulled out of the garbage bag box 1 by the rotation of the lower bag drive wheel 3.

[0038] This embodiment provides a novel and more stable and reliable bag-dropping method. Its core principle lies in utilizing the friction or meshing force generated by rotating rollers to pull the garbage bag 6, replacing the traditional push-rod or negative pressure suction method. This structure fundamentally avoids the overhead space required by the push-rod mechanism, making the overall layout more flexible and suitable for products with limited top space or requiring an open structure (such as some smart trash cans or cat litter boxes). Simultaneously, the wheel-driven rotating bag-dropping action is smoother, more continuous, and gentler, completely overcoming the shortcomings of negative pressure methods, such as high noise levels and susceptibility to bag material or sealing issues, significantly improving the success rate and reliability of the bag-dropping action.

[0039] Furthermore, in one specific embodiment, the garbage bag box 1 has an annular quadrilateral structure; the number of the lower bag driving wheel 3 and the lower bag driven wheel 4 are four, forming four pairs of transmission pairs; the four pairs of transmission pairs are respectively arranged on the four sides of the annular quadrilateral garbage bag box 1; the driving mechanism 5 synchronously drives the four lower bag driving wheels 3 to rotate, so that the garbage bag 6 is evenly discharged from all four sides.

[0040] In this embodiment, the annular quadrilateral garbage bag box 1 ensures that the garbage bags 6 inside also have a corresponding shape. By simultaneously setting four pairs of drive wheels on the four sides and providing synchronous power from the same drive mechanism 5, it is ensured that during the bag-pulling process, the four corners of the garbage bag 6 are simultaneously, equally, and uniformly subjected to traction force. This design fundamentally solves the problem of uneven bag dispensing caused by single-point or asymmetrical force application in traditional push-rod bag dispensing systems, where one side is pulled out while the other side remains stuck. It ensures the integrity and reliability of each bag dispensing action and is key to achieving efficient automatic packaging.

[0041] Furthermore, in one specific embodiment, the drive mechanism 5 includes a drive motor 51, a worm gear assembly 52 driven by the drive motor 51, and a drive link 53 connected to the output end of the worm gear assembly 52; the drive link 53 has four links, and the four lower bag drive wheels 3 are respectively fixedly installed on the four drive links 53, and the four drive links 53 are sequentially meshed and transmitted through the helical gear set 54 provided thereon.

[0042] In this embodiment, the drive motor 51 provides the initial power. The worm gear assembly 52 serves to reduce speed and increase output torque, ensuring sufficient force to pull the entire roll of garbage bags. The reverse self-locking characteristic of the worm gear assembly 52 prevents the garbage bags from retracting under their own tension during bag feeding intervals or stops. When the drive linkage 53 rotates, it synchronously drives the four bag feeding drive wheels 3 to rotate synchronously. The design of the helical gear set 54 allows for changing the direction of power transmission and ensures that the drive motor 51 synchronously drives the four bag feeding drive wheels 3, guaranteeing the synchronicity of the four wheel rotations, thereby achieving a uniform bag feeding effect from all four sides. This drive scheme has a compact structure, high transmission efficiency, and simple control.

[0043] Furthermore, in one specific embodiment, the lower bag drive wheel 3 is a gear; the lower bag driven wheel 4 is a gear that can mesh with the lower bag drive wheel 3.

[0044] In this embodiment, gear meshing is used for transmission. The advantage of this method is precise transmission without slippage, ensuring strict synchronization of the rotational speeds of the driving wheel 3 and the driven wheel 4, thus providing stable and accurate traction. It is particularly suitable for applications requiring high precision in controlling the length of the lower bag.

[0045] Furthermore, in one specific embodiment, both the lower bag driving wheel 3 and the lower bag driven wheel 4 are friction wheels with flat surfaces, which are driven to move by the friction generated by clamping the garbage bag 6.

[0046] In this embodiment, friction drive is employed. The friction wheel has a flat surface, and its movement is driven by the static friction generated between it and the surface of the garbage bag 6. This solution has wider applicability, a simpler structure, and lower cost. Reliable transmission can be achieved as long as sufficient clamping force is ensured.

[0047] Furthermore, in one specific embodiment, the four pairs of transmission pairs are respectively disposed at the middle positions of the four sides of the annular quadrilateral garbage bag box 1.

[0048] In this embodiment, the four pairs of transmission pairs are respectively arranged at the middle positions of the four sides of the annular quadrilateral garbage bag box 1, which can further improve the uniformity of garbage bag 6 exiting from the four sides.

[0049] Furthermore, in one specific embodiment, the garbage bag box 1 is detachably mounted on the bag box base 2.

[0050] In this embodiment, the detachable design makes the garbage bag container 1 an independent, replaceable consumable module. When the garbage bags in the container are used up, the user only needs to remove the old garbage bag container 1 and replace it with a new container pre-filled with garbage bags. The operation is extremely simple and quick, greatly improving the user experience and facilitating the commercial application of the product.

[0051] Furthermore, in one specific embodiment, the drive mechanism 5 also includes a control unit for controlling the number of rotations of the lower bag drive wheel 3 to precisely control the length of the lower bag.

[0052] In this embodiment, the control unit (not shown in the figure, but may be an MCU or a dedicated circuit) can preset or receive instructions to precisely control the number of rotations or angle of the drive motor 51. Since the length of the lower bag is proportional to the circumference of the drive wheel 3, the length of the pulled-down garbage bag 6 can be precisely controlled by controlling the number of rotations. This ensures that the bag length provided each time is consistent, avoiding waste and ensuring that packaging requirements are met, thus achieving both intelligence and energy saving.

[0053] Furthermore, in one specific embodiment, the bag base 2 is provided with a detection sensor for detecting whether the garbage bag box 1 is installed in place.

[0054] In this embodiment, a detection sensor (such as a photoelectric sensor or a mechanical switch, not shown in the figure) is used to detect whether the garbage bag container 1 has been correctly and completely installed on the bag container base 2. Only when the installation is detected to be in place will the control system allow the bag-dropping operation to be started, thereby preventing problems such as bag-pulling failure, mechanism idling or damage caused by improper bag container installation, and improving the safety and reliability of the equipment.

[0055] Furthermore, in one specific embodiment, an automatic packaging device is provided, including a roller bag-discharging mechanism as described in any of the preceding claims, for extracting garbage bags 6 from garbage bag box 1.

[0056] In this embodiment, the roller bag-dispensing mechanism serves as a core functional module and can be widely applied to various intelligent devices that require automatic plastic bag dispensing, such as automatic packaging smart trash cans and automatic packaging cat litter boxes. Its compact structure, reliable operation, and low noise significantly improve the overall performance of the product and the user experience.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
