Description

Technical Field

[0001] This application relates to the field of packaging box production equipment technology, and in particular to a packaging box specification screening mechanism and equipment. Background Technology

[0002] In the packaging production and logistics sorting sector, automated screening of multi-sized packaging boxes has always been a technical challenge. Traditional screening equipment often uses vibrating screens and conveyor belts in conjunction with manual sorting or fixed-size screens for grading, resulting in low efficiency, frequent manual intervention, and large equipment footprint. For example, fixed screens require multiple adjustments or changes to the screen aperture size, making them difficult to adapt to continuous production needs; vibrating screens are prone to causing wear on the surface of packaging boxes and have poor compatibility with irregularly shaped packaging boxes. In addition, the coordination between material supply and screening actions in existing equipment is insufficient, often resulting in phenomena such as material jamming, stacking blockage, or unstable screening accuracy. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned problems by providing a packaging box specification screening mechanism and equipment.

[0004] The technical solution of this application is implemented as follows:

[0005] In a first aspect, this application provides a packaging box specification screening mechanism, the screening mechanism comprising:

[0006] spindle;

[0007] A spiral pusher plate extends spirally along the outer side of the main shaft, and the pitch space of the spiral pusher plate is used to accommodate a packaging box;

[0008] A screening plate is installed on the side of the spiral pusher plate. The screening plate is axially parallel to the main shaft. The screening plate has several screening grooves of different specifications and is inclined.

[0009] The rotation of the main shaft causes the spiral of the spiral pusher plate to continuously move relative to the screening plate along the axial direction of the main shaft, thereby pushing the packaging box in the pitch space to move along the length direction of the screening plate. At the same time, the packaging box leans against the screening plate. When the packaging box reaches the screening groove corresponding to its specifications, the packaging box passes through the screening groove and through the screening plate.

[0010] The advantages or beneficial effects of the above technical solutions include at least the following:

[0011] Secondly, this application also provides a device equipped with a packaging box specification screening mechanism as described above.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following:

[0013] 1. Automated screening and continuous operation: Through the dynamic cooperation of the spiral pusher plate and the screening plate, the packaging boxes are automatically pushed and accurately screened under the drive of the main shaft rotation, without the need for manual intervention, which significantly improves sorting efficiency.

[0014] 2. Structural integration and space optimization: The inclined layout of the spiral pusher plate and the screening trough, combined with the linkage design of the feeding frame, forms a compact material flow path, reducing the space occupied by the equipment, while ensuring that the packaging boxes slide down into the corresponding screening trough in sequence.

[0015] 3. Flexible adaptation and low-damage sorting: The gradually changing size design of the screening tank, combined with the tilting and sliding of the packaging box according to its own weight, can adapt to the screening needs of packaging boxes of different sizes and avoid packaging damage caused by mechanical compression.

[0016] 4. Collaborative feeding and precise timing control: The feeding mechanism, which links the turntable pusher and the compression spring, achieves precise matching between the feeding rhythm and the spatial position of the screw pitch through synchronous drive of the main shaft, effectively preventing material accumulation or idling.

[0017] 5. Expandability and easy maintenance: The modular design of the screening plate and spiral pusher plate makes it easy to quickly adjust or change specifications according to production needs, reducing equipment modification costs and adapting to diverse production scenarios.

[0034] A packaging box specification screening mechanism, the screening mechanism comprising:

[0035] Main spindle 10 is horizontally mounted in the equipment on which the structure is installed;

[0036] Spiral pusher plate 20, such as Figure 4 As shown, the spiral pusher plate 20 extends spirally along the outer side of the main shaft 10, and the pitch space of the spiral pusher plate 20 is used to accommodate the packaging box 80, such as... Figure 5 As shown, each pitch space formed by the spiral pusher plate 20 can hold a packaging box 80;

[0037] A screening plate 30 is installed on the side of the spiral pusher plate 20. The screening plate 30 is axially parallel to the main shaft 10. Several screening grooves 31 of different specifications are opened on the screening plate 30. The screening plate 30 is inclined. Figure 9 As shown;

[0038] Based on the above structure, as the main shaft 10 rotates, the spiral line of the spiral pusher 20 is continuously pushed relative to the screening plate 30 along the axial direction of the main shaft 10, so as to push the packaging box 80 in the pitch space to move along the length direction of the screening plate 30. At the same time, the packaging box 80 leans against the screening plate 30. When the packaging box 80 reaches the screening groove 31 corresponding to its specifications, the packaging box 80 passes through the screening groove 31 and passes through the screening plate 30 to screen the packaging box 80.

[0039] Specifically, with Figure 1 For example, if the spiral pusher 20 is set to rotate clockwise, the main shaft 10 will rotate clockwise. Figure 3 For example, the spiral pusher 20 pushes the packaging box 80 from left to right. At this time, the size of the screening trough 31 on the screening plate 30 gradually increases from left to right. Figure 5 As shown, since the screening plate 30 is inclined, when the packaging box 80 reaches the screening trough 31 corresponding to its specifications, the packaging box 80 passes through the screening plate 30 through the screening trough 31 to be screened.

[0040] Based on the above structure, the screening agencies further include:

[0041] The feeding frame 40 is installed on the top of the spiral push plate 20. Specifically, when the spiral push plate 20 is set to rotate clockwise, the feeding frame 40 is located on the left side of the spiral push plate 20. The feeding frame 40 includes a feeding area 41 and a storage area 42. The storage area 42 is used to store the packaging boxes 80 to be screened. The feeding area 41 is located on the top of the spiral push plate 20. The storage area 42 can stack multiple packaging boxes 80 along the height.

[0042] Push rod 50 is slidably installed in unloading frame 40 to push packaging box 80 in storage area 42 to unloading area 41. Push rod 50 is located at the bottom of storage area 42. When push rod 50 pushes packaging box 80, it will push the packaging box 80 at the bottom to unloading area 41, so that packaging box 80 in unloading area 41 falls into the pitch space of spiral push plate 20.

[0043] A turntable 60 is fixedly installed at one end of the spindle 10, and a pusher 61 is installed on the turntable 60.

[0044] A compression spring 51 is sleeved on a push rod 50. A baffle 52 is installed on the push rod 50. One end of the compression spring 51 abuts against the baffle 52, and the other end abuts against the inner wall of the feeding frame 40.

[0045] As the main shaft 10 rotates, the turntable 60 rotates. When the push block 61 aligns with the push rod 50, the compression spring 51 is compressed, pushing the packaging box 80 in the storage area 42 into the unloading area 41. Figure 7 As shown, it should be noted that the position of the push block 61 determines the timing of the push rod 50. Therefore, when designing the position of the push block 61, it is necessary to ensure that when the push block 61 pushes out the push rod 50, the pitch space of the spiral push plate 20 is in the feeding area 41 of the feeding frame 40, so that the packaging box 80 can fall directly into the pitch space instead of falling directly onto the spiral push plate 20.

[0046] Furthermore, the push block 61 also has a ramp section 62 that gradually decreases along the outer edge of the turntable 60. As the turntable 60 rotates, the tail of the push rod 50 can reach the top of the push block 61 through the ramp section 62, so as to realize the push block 61 pushing the push rod 50.

[0047] The screening mechanism further includes a drive motor housing 70, which houses a motor, such as... Figure 6 As shown, the motor is used to drive the spindle 10 to rotate.

[0048] An embodiment of this utility model also provides a device equipped with a packaging box specification 80 screening mechanism as described above.

[0049] In the description of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0050] Those skilled in the art should understand that the above embodiments are merely for illustrative purposes and are not intended to limit the scope of this application. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of this application.
