Description

Technical Field

[0001] This utility model belongs to the field of food packaging bag processing technology, and in particular, it is a cutting edge collection device for food packaging bag processing. Background Technology

[0002] Food packaging bags, as an important carrier for various types of food packaging, play a crucial role in the production process. These bags not only need to possess excellent protective properties to ensure the safety and freshness of food during storage and transportation, but also must comply with relevant hygiene standards and regulations to protect consumer health. Edge trimming is an indispensable step in the manufacturing process of food packaging bags. Since food packaging bags are usually made from rolls of material, excess material or irregular corners often appear at the edges during the cutting process into individual bags, necessitating the use of edge trimming and collection devices.

[0003] Chinese patent CN222116238U discloses a cutting edge collection device for food packaging bag processing, comprising a worktable. Symmetrical fixing blocks are fixedly connected to the upper surface of the worktable. A motor is fixedly connected to one side of each fixing block. A lead screw is fixedly connected to the output end of the motor. The lead screw is rotatably connected inside the fixing blocks. A hinge block is threadedly connected to the outer wall of the lead screw. A support rod is rotatably connected inside the hinge block. A second hinge block is rotatably connected to the outer wall of the support rod. A limit rod is slidably connected to the inner wall of the second hinge block. In this invention, the coordination of the worktable, fixing blocks, motor, lead screw, hinge blocks, support rod, second hinge block, limit rod, second fixing block, conveyor belt, and connecting components achieves easy height adjustment, improving the practicality of the cutting edge collection device.

[0004] Although the above-mentioned equipment can adjust the height of the conveyor belt during use, thereby increasing its applicability, given the wide variety of packaging bags and the varying sizes of the waste edges after trimming, smaller waste edges are easily scattered during transport and difficult to collect and process effectively. In addition, when too many waste edges accumulate in the crushing box and cannot be crushed in time, they are prone to causing blockages at the inlet or inside of the crushing box. Therefore, when the conveyor belt transports edges, small waste edges are prone to scattering and blockage, and the inability to adjust according to the size of the edges limits the processing speed. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting edge collection device for food packaging bag processing, so as to solve the problems in the prior art where small waste edges are easily scattered and blocked when conveying edges, and cannot be adapted to edges of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cutting edge collection device for food packaging bag processing includes a crushing box and a connecting box. The connecting box is installed above the crushing box. A conveying mechanism is provided on one side of the connecting box. An adjusting mechanism is provided around the conveying mechanism.

One end of a portion of the upward inclined guide plate is aligned with the upper end of the second flow guiding half-ring, and both ends of another portion of the upward inclined guide plate are aligned with the upper ends of both the first flow guiding half-ring and the second flow guiding half-ring.

[0009] Preferably, a sliding groove is provided above the upper conveying frame and below the lower conveying frame, and an upper support and a lower support are slidably connected inside the two sliding grooves respectively.

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

[0016] This utility model, through the coordinated arrangement of a conveying mechanism, an adjusting mechanism, a lower air guide box, and an upper air guide box, can form a spiral vortex within the conveying channel formed by the upper and lower conveying frames to transport the edges and corners of waste materials. This not only effectively prevents small waste edges and corners from scattering during the conveying process, but also prevents waste materials from accumulating inside the crushing box and causing blockages.

[0017] This invention, through the cooperation of a conveying mechanism and an adjusting mechanism, allows the upper and lower inclined guide plates to retract into the inner wall of the conveying channel when some corners of waste are blocked by guide plates during the conveying process of the conveying channel formed by the upper and lower conveying frames. This results in a flat inner wall of the conveying channel, which not only facilitates cleaning and maintenance but also adapts to the corners of waste of different sizes, shapes, and textures, thus improving the applicability and flexibility of the equipment.

[0034] The adjusting mechanism 6 includes a top plate 61 and a bottom plate 62, as well as an upper inclined guide plate 66 and a lower inclined guide plate 68 evenly arranged. The top plate 61 is installed above the upper conveying frame 51, and the bottom plate 62 is installed below the lower conveying frame 52.

[0038] In this embodiment, the downward inclined guide plate 68, the second guide semi-ring 57, the upward inclined guide plate 66, and the first guide semi-ring 56 are aligned end to end and arranged in a spiral pattern, thereby guiding the airflow.

[0039] In a further embodiment, sliding grooves 55 are provided above the upper conveying frame 51 and below the lower conveying frame 52, and upper support 65 and lower support 67 are slidably connected inside the two sliding grooves 55 respectively.

[0040] In this embodiment, the top plate 61 covers the sliding groove 55 above the upper conveying frame 51, while the bottom plate 62 covers the sliding groove 55 below the lower conveying frame 52, thereby allowing the sliding groove 55 to restrict the sliding of the upper support 65 and the lower support 67.

[0041] In a further embodiment, the upper inclined guide plate 66 is located below the top plate 61, the upper bracket 65 is located between the upper inclined guide plate 66 and the top plate 61, and the upper bracket 65 is fixedly connected to the upper inclined guide plate 66.

[0042] In this embodiment, the upper inner wall of the conveying channel formed by the upper conveying frame 51 and the lower conveying frame 52 is provided with a groove for the upper inclined guide plate 66 to be embedded, and the lower inner wall is provided with a groove for the lower inclined guide plate 68 to be embedded. Both of the embedding grooves are connected to the sliding groove 55. In addition, the first guide ring 56 and the second guide ring 57 are also fixed in the conveying channel by plugging them in.

[0043] In a further embodiment, the downward inclined guide plate 68 is located above the base plate 62, and the lower bracket 67 is located between the base plate 62 and the downward inclined guide plate 68, and the lower bracket 67 is fixedly connected to the downward inclined guide plate 68.

[0044] In this embodiment, the inclined directions of the upper inclined guide plate 66 and the lower inclined guide plate 68 are opposite, as are the first flow guiding half ring 56 and the second flow guiding half ring 57, so that they can be integrally formed into a spiral guide plate.

[0045] In a further embodiment, a drive motor 63 is installed above the top plate 61, and a positive and negative lead screw 64 is installed at the output end of the drive motor 63. The upper and lower ends of the positive and negative lead screw 64 are respectively rotatably connected to the top plate 61 and the bottom plate 62.

[0046] In this embodiment, the top plate 61, the upper bracket 65, the lower bracket 67, and the bottom plate 62 all have protruding ear plates at the positive and negative lead screws 64, which facilitates the passage of the positive and negative lead screws 64 and their threaded connection.

[0047] In a further embodiment, the upper and lower ends of the positive and negative lead screw 64 are respectively threaded to the upper bracket 65 and the lower bracket 67.

[0048] In this embodiment, when the drive motor 63 operates, it can drive the positive and negative lead screws 64 to rotate, thereby manipulating the two upper supports 65 and the lower support 67 to move closer or further apart, thereby controlling whether the upper inclined guide plate 66 and the lower inclined guide plate 68 are in a raised state. When in a raised state, they are used to cooperate with the guide semi-ring 56 and the guide semi-ring 57 to spiral guide the airflow. When not in a raised state, they are used to ensure that the upper and lower inner walls of the conveying channel are flat, which is convenient for cleaning and maintenance.

[0049] In a further embodiment, two upper air inlet slots 54 are provided at the chamfered corner on one side of the upper conveying frame 51, and the upper air guide box 8 is installed around the upper air inlet slots 54. Two lower air inlet slots 53 are provided at the chamfered corner on the side of the lower conveying frame 52 away from the upper air inlet slots 54, and the lower air guide box 7 is installed around the lower air inlet slots 53.

[0050] In this embodiment, when the blower 9 is operating, it will deliver airflow to the chamfered corner in the conveying channel through the lower air guide box 7 and the upper air guide box 8. With the guidance of the lower inclined guide plate 68, the second guide ring 57, the upper inclined guide plate 66 and the first guide ring 56, the airflow will flow in a spiral shape.

[0051] The working principle of this utility model is as follows:

[0052] When the blower 9 is operated by an external controller, air is blown into the inner side of the upper conveying frame 51 and the lower conveying frame 52 through the lower air guide box 7 and the upper air guide box 8. At this time, the airflow enters in the tangential direction of the lower conveying frame 52 and the tangential direction of the upper conveying frame 51, and is guided by the lower inclined guide plate 68, the second guide semi-ring 57, the upper inclined guide plate 66 and the first guide semi-ring 56 in sequence, so that the airflow forms a spiral vortex inside the upper conveying frame 51 and the lower conveying frame 52. When one end of the upper conveying frame 51 and the lower conveying frame 52 is connected to the waste cutting edge discharge port, the waste can be spirally conveyed to the inside of the connecting box 3. This not only avoids the scattering of small waste edges and corners, thereby improving the integrity of edge and corner collection, but also increases the travel distance of the conveyed waste, thereby avoiding the accumulation of waste inside the crushing box 1 and causing blockage.

[0053] When some corners are blocked by the upper inclined guide plate 66 or the lower inclined guide plate 68, the controller can make the drive motor 63 operate, so that the upper bracket 65 and the lower bracket 67 embedded above the upper conveying frame 51 and below the lower conveying frame 52 are moved away from each other, so that the upper inclined guide plate 66 and the lower inclined guide plate 68 are no longer inserted into the inner wall of the upper conveying frame 51 and the lower conveying frame 52, thereby making the inner wall of the upper conveying frame 51 and the lower conveying frame 52 flat, thus adapting to different waste characteristics and making it easier to clean and maintain.

[0054] 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.
