[0045] For medical packaging bags, in the production process, the method of using a frame and a feeding mechanism is usually adopted to transport the raw materials to be processed through the functional positions, thereby completing the processing of medical packaging bags. However, the above feeding method lacks flexibility and cannot effectively meet the production requirements of high efficiency.

[0046] In view of this, the embodiments of the present utility model provide a feeding device that can switch the feeding line or adjust the material type during the production process. A traction module is provided on the frame. The traction module can, according to the requirements of medical guarantee bags, traction the base film to dock with the upper film, or traction the base film to dock with the lower film, improving the flexibility of the feeding device, reducing the feeding time, and meeting the production requirements of high efficiency.

[0047] To better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the accompanying drawings.

[0048] Please refer to Figure 1 、 Figure 2 and Figure 3 , a feeding device proposed by the embodiments of the present utility model for improving the flexibility of the feeding device, includes:

[0049] Frame 10, on which a conveying line is provided for conveying the base film to be processed;

[0050] Upper feeding mechanism 20, which straddles above the frame 10 for conveying the upper film to be processed;

[0051] Lower feeding mechanism, which is provided on the frame 10 and is located below the conveying line for conveying the lower film to be processed; and

[0052] Traction module 40, which is provided on the frame 10 and is located at the end of the conveying line for selectively traction the upper film or the lower film to dock with the base film to form the product to be processed.

[0053] In the technical solution adopted in this embodiment, the frame 10 provides a support structure framework for the main body of the feeding device. A conveyor line is arranged on the frame 10, which can continuously convey the base film to be processed. The upper feeding mechanism 20 is arranged above the conveyor line and can be used to convey the upper film to be processed. The lower feeding mechanism is arranged below the conveyor line and can be used to convey the lower film to be processed. The traction module 40 is arranged on the frame 10 and can selectively traction the upper film or the lower film to be docked with the base film to form a product to be processed. It can be understood that during the operation of the feeding device, the upper feeding mechanism 20 and the lower feeding mechanism can convey different types of materials. The traction module 40 can first traction the lower film to be docked with the base film to form a product to be processed and feed it to the functional position. During this process, the upper film can be conveyed to the turning point for waiting first. If the material type needs to be adjusted, the traction module 40 can be converted to traction the upper film to be docked with the base film to form a product to be processed and feed it to the functional position, reducing the material change time and the conveying time, and vice versa. The technical solution proposed in the embodiment of the present invention improves the flexibility of the feeding device and can meet the production requirements of high efficiency.

[0054] Specifically, the feeding device includes a frame 10, an upper feeding mechanism 20, a lower feeding mechanism, and a traction module 40.

[0055] The frame 10 can be made of metal materials such as stainless steel and iron, with a certain load-bearing capacity, and can constitute the main support structure of the feeding device for installing and fixing other components.

[0056] The upper feeding mechanism 20 is arranged above the frame 10 and is used to convey the upper film to be processed. The upper feeding mechanism 20 can be a roller conveyor belt, and the roller conveyor belt can realize the conveyance of the upper film to be processed. By setting a motor to drive the roller conveyor belt to rotate, the upper film can be driven to be continuously conveyed, so as to facilitate the next step of production. The upper feeding mechanism 20 can be fixedly installed on the frame 10, or can be separately arranged across both sides of the frame 10, which is not limited here. In addition, the height between the upper feeding mechanism 20 and the frame 10 can be set according to the height of the functional position.

[0057] The lower feeding mechanism is arranged below the frame 10 and is used to convey the lower film to be processed. The lower feeding mechanism can be the above-mentioned roller conveyor belt, and the roller conveyor belt can realize the conveyance of the lower film to be processed. By setting a motor to drive the roller conveyor belt to rotate, the lower film can be driven to be continuously conveyed, so as to facilitate the next step of production.

[0058] The traction module 40 is used to realize the selection of the traction base film to abut against the upper film or the lower film for feeding the functional position. It can be understood that the traction path of the base film can be changed through the traction module 40, so that when it is necessary to adjust the material type, the base film can be docked with the material on another feeding mechanism, thereby reducing the material change time and the conveying time and improving the flexibility of the feeding device. The traction module 40 can be a traction guide roller or a rotating rod. The traction guide roller or the rotating rod can first traction the lower film to dock with the base film for feeding the next functional position. When it is necessary to adjust the material type, first disconnect the base film and the lower film, and then change the rotation direction of the traction guide roller or the rotating rod, so that it rotates in the opposite direction. At this time, the traction guide roller or the rotating rod can traction the base film to dock with the upper film for feeding the next functional position, thereby improving the flexibility of the feeding device and meeting the high-efficiency production requirements. The disconnection method of the lower film, the upper film or the base film can be an artificial disconnection method, or a cutter can be set to disconnect, which is not limited here.

[0059] Further, referring to Figure 1 、 Figure 2 , in an embodiment of the present invention, the traction module 40 includes:

[0060] The mounting frame 41 is arranged on the frame 10 and located at the end of the conveying line;

[0061] The steering guide roller 42 is rotatably connected to the mounting frame 41 for traction the base film;

[0062] The upper traction roller 43 is rotatably connected to the mounting frame 41 and located above the steering guide roller 42 for traction the upper film;

[0063] The lower traction roller 44 is rotatably connected to the mounting frame 41 and located below the steering guide roller 42 for traction the lower film; and

[0064] The driving part is drivingly connected to the steering guide roller 42 to drive the steering guide roller 42 to rotate in the forward direction to traction the base film to dock with the upper film, or drive the steering guide roller 42 to rotate in the reverse direction to traction the base film to dock with the lower film.

[0065] In the technical solution adopted in this embodiment, the traction module 40 may further include a mounting frame 41, a steering guide roller 42, an upper traction roller 43, a lower traction roller 44, and a driving part. In this embodiment, the mounting frame 41 is spanned across the end of the conveyor line, generally made of sheet metal parts, and can provide a supporting function. The driving part may be a servo motor, which is drivingly connected to the steering guide roller 42. The steering guide roller 42 in this embodiment can rotate in the forward direction first or in the reverse direction first, and no limitation is made here. In the following description, the rotation in the forward direction first is taken as an introduction. In this implementation, the servo motor drives the steering guide roller 42 to rotate in the forward direction, and can traction the base film to be conveyed from above the steering guide roller 42. At this time, the upper traction roller 43 operates to traction the upper film to move, so that the base film is docked with the upper film and feeds the material together to the next functional position. The servo motor drives the steering guide roller 42 to rotate in the reverse direction, and can traction the base film to be conveyed from below the steering guide roller 42. At this time, the lower traction roller 44 operates to traction the lower film to rotate, so that the base film is docked with the lower film and feeds the material together to the next functional position.

[0066] Further, referring to Figure 1 、 Figure 2 In an embodiment of the present invention, the traction module 40 further includes auxiliary guide rollers 45, and two are provided at intervals along the height direction of the mounting frame 41. Among them, one auxiliary guide roller 45 is correspondingly arranged with the upper traction roller 43, and is used to abut against the lower part of the base film to make the base film fit with the upper film. The other auxiliary guide roller 45 is correspondingly arranged with the lower traction roller 44, and is used to abut against the upper part of the base film to make the base film fit with the lower film.

[0067] In the technical solution adopted in this embodiment, by providing the auxiliary guide rollers 45, the tension between the upper film and the base film or between the lower film and the base film can be increased, providing strong support for the product to be processed, and improving the reliability of the traction module 40. The auxiliary guide rollers 45 can be provided with two, or can be provided with multiple. The height difference between the auxiliary guide roller 45 and the upper traction roller 43 or the height difference between the auxiliary guide roller 45 and the lower traction roller 44 can be set according to actual use, and no limitation is made here.

[0068] Further, referring to Figure 3 In an embodiment of the present invention, the feeding device further includes a limiting component 50, which is arranged on the mounting frame 41. The limiting component 50 includes:

[0069] A support rod 51, which is connected to the mounting frame 41; and

[0070] Limiting parts 52, two are provided at intervals along the length direction of the support rod 51. Each limiting part 52 is movably connected to the support rod 51. The adjacent sides of the two limiting parts 52 are respectively abutted against the two sides of the base film and the upper film, or against the two sides of the base film and the lower film.

[0071] In the technical solution adopted in this embodiment, the feeding device may further include a limiting component 50. The limiting component 50 is used to ensure the precise positioning of the material during the feeding process, and reduce the possibility of the upper film or the lower film shifting or misaligning during the docking process. In this embodiment, the limiting component 50 may further include a support rod 51 and a limiting portion 52. The support rod 51 is used to provide a support frame for the limiting portion 52 to ensure the stability during the positioning process. The limiting portion 52 may be a limiting plate or a limiting block. Two limiting plates or limiting blocks are provided. One of the limiting plates or limiting blocks abuts against one side of the product to be processed, and the other limiting plate or limiting block abuts against the other side of the product to be processed. Moreover, the limiting portion 52 is movably connected to the support rod 51. In this way, according to the width of the product to be processed, the limiting plate or the limiting block can slide on the support rod 51, so as to abut against both sides of the product to be processed to achieve precise positioning. It can be understood that the limiting plate or the limiting block can be set in a curved shape, and the length of the limiting plate or the limiting block is suitable for the limiting plate or the limiting block to abut against the product to be processed. Of course, in order to improve the accuracy and flexibility of the limiting component 50, an adjusting member may be provided at one end of the support rod 51, so that the support rod 51 can be rotated, so that the position of the limiting portion 52 can be adjusted according to the characteristics of different materials.

[0072] Further, referring to Figure 3 , Figure 4 , in an embodiment of the present utility model, the limiting component 50 further includes a locking portion 53. A through avoidance hole is provided on the limiting portion 52. One end of the locking portion 53 can pass through the avoidance hole and abut against the support rod 51 to make the limiting portion 52 in a locked state, or the locking portion 53 is separated from the support rod 51 to make the limiting portion 52 in an active state.

[0073] In the technical solution adopted in this embodiment, the limiting component 50 may further include a locking portion 53. A through avoidance hole is provided on the limiting portion 52. In this embodiment, the locking portion 53 may be a bolt or a threaded rod. The bolt or the threaded rod passes through the avoidance hole and is threadedly connected to the avoidance hole. An acting force is applied to the bolt or the threaded rod to make the end of the bolt or the threaded rod move in the direction close to the support rod 51 until the bolt or the threaded rod abuts tightly against the support rod 51, so as to fix the limiting portion 52. An acting force in the opposite direction is applied to the bolt or the threaded rod to make the end of the bolt or the threaded rod move in the direction away from the support rod 51, so that the bolt or the threaded rod is separated from the support rod 51, so that the limiting portion 52 can slide on the support rod 51. It can be understood that by providing the locking portion 53, the limiting portion 52 can be accurately positioned at the required position, improving the accuracy of the overall structure.

[0074] Further, referring to Figure 1 , in an embodiment of the present utility model, the upper feeding mechanism 20 includes:

[0075] The loading rack 21 is arranged above the machine frame 10; and

[0076] The upper guide rollers 22, at least two upper guide rollers 22 are rotatably connected to the loading rack 21;

In this embodiment, the loading rack 21 is used to carry and support the upper film to be processed. The upper guide rollers 22 are arranged on the loading rack 21 and are used to guide and stabilize the conveying of the upper film. It can be understood that the height of the loading rack 21 can be set according to the actual situation, and the height of the loading rack 21 is greater than the height of the functional position. In this way, when the functional position is arranged on the machine frame 10, the loading rack 21 can straddle this functional position to supply materials to the next functional position.

[0079] Further, referring to Figure 1 , in an embodiment of the present invention, the lower feeding mechanism includes at least two lower guide rollers 30, at least two lower guide rollers 30 are rotatably connected to the machine frame 10, and a lower guide roller 30 is correspondingly arranged below the front end and the end of the conveying line.

[0081] In this embodiment, the lower guide rollers 30 can be arranged on the machine frame 10 and are used to guide and stabilize the conveying of the lower film. It can be understood that a lower guide roller 30 is correspondingly arranged below the front end and the end of the conveying line, so that the turning of the lower film can be facilitated. The number of the lower guide rollers 30 can be correspondingly set according to the length of the machine frame 10 to ensure that the conveyed lower film has sufficient tension.

[0082] The present invention also provides a processing device, which includes a functional structure 60 and the feeding device of each of the above embodiments. The specific structure of the feeding device refers to the above embodiments. Since this processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated herein one by one.

The hot pressing position can be set to one, which can perform hot pressing on the product to be processed that has completed docking; it can also be set to two, that is, one is arranged upstream of the traction module 40 and the other is arranged downstream of the traction module 40. At this time, the hot pressing position located upstream can first heat-seal a special label or seal on the base film. During this process, the upper film and the lower film can respectively cross this hot pressing position through the upper feeding mechanism 20 and the lower feeding mechanism. After that, the base film that has completed preliminary processing can be selectively docked with the upper film or the lower film to form a product to be processed and sent to the downstream hot pressing position for re-heat sealing. The functional structure 60 can also be set to multiple, which is not limited here.
