Description

Technical Field

[0001] This utility model relates to a height detection device for items inside a packaging box, which is used to detect the height of items inside the packaging box and belongs to the field of packaging machinery technology. Background Technology

[0002] In industries such as logistics, packaging boxes are often used to package goods. These boxes are generally produced to fixed dimensions, but the sizes of the items vary greatly. Packaging boxes typically need to be cut to fit the items, preventing them from shifting inside and ensuring safe and stable transport. The height of the box to be cut depends on the height of the items inside. This requires knowing the height of the items and cutting the box accordingly (usually by cutting and separating the four corners, then folding the four separated sides). Utility Model Content

[0003] The purpose of this invention is to provide a device for detecting the height of items inside a packaging box, which can automatically detect the height of the items inside the packaging box and obtain the height information of the items.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0005] A packaging box item height detection device includes a detection plate connected to a power component via an elastic telescopic component. The power component drives the detection plate to move up and down via the elastic telescopic component. A sensor is installed next to the elastic telescopic component to detect its compression. The power component drives the detection plate downwards into the packaging box. When the detection plate touches the item, the elastic telescopic component compresses, the sensor receives a signal, and the power component stops. The height of the item inside the packaging box is obtained by measuring the distance the detection plate moves with the power component. The height of the item inside the packaging box is then calculated by subtracting the distance the detection plate moves with the power component from the depth of the packaging box.

[0006] Alternatively, the elastic telescopic component includes a connecting plate connected to a power component. The connecting plate has a placement hole into which a telescopic rod is placed. The head of the telescopic rod has a limiting head located above the connecting plate. The tail of the telescopic rod is connected to a detection plate. A spring is fitted over the telescopic rod between the detection plate and the connecting plate. The telescopic rod is hung on the placement hole via the limiting head, and the connection of the tail of the telescopic rod to the detection plate enables the connection of the detection plate.

[0007] Alternatively, the power component is an electric cylinder, and the piston rod of the electric cylinder drives the detection plate to move up and down through an elastic telescopic component.

[0008] To limit the movement direction of the detection plate, a guide rod is provided on the detection plate, and a guide sleeve is fitted over the guide rod, with the guide sleeve being fixedly installed. Since the guide rod is fitted inside the guide sleeve, and the position of the guide sleeve is fixed, the movement direction of the detection plate is thus fixed. Preferably, there are two sets of guide rods and guide sleeves.

[0009] Alternatively, the sensor is a proximity switch, which is mounted on a power component or a component fixedly connected to the power component. The corresponding sensing element of the proximity switch is mounted on a detection plate or a component fixedly connected to the detection plate. Driven by the power component, the detection plate moves downward. When the detection plate touches the item, the elastic telescopic component compresses, causing a change in the position of the proximity switch and the sensing element, thus obtaining a signal. This signal can then control the power component to stop moving. At this point, the height of the item inside the packaging box is obtained by subtracting the distance the power component moves the detection plate within the packaging box from the depth of the packaging box.

[0010] Preferably, the detection plate is perforated, which facilitates air expulsion and reduces resistance when the detection plate comes into contact with the items inside the packaging box.

[0011] This utility model has a simple structure and realizes automatic detection of the height of the items inside the packaging box, laying the foundation for the packaging box to securely package the items. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] Figure 1 This is a schematic diagram of a device for detecting the height of items in a package.

[0014] Figure 2 This is a schematic diagram of the packaging box item height detection device from another angle. Detailed Implementation

[0015] like Figure 1-2 As shown, the packaging box item height detection device includes an electric cylinder 1 and a detection plate 9. The detection plate 9 is hollow. The piston rod 2 of the electric cylinder 1 is connected to a connecting plate 3. The connecting plate 3 has two left and right distributed placement holes (not shown). A telescopic rod 5 is placed in each placement hole. The head of the telescopic rod 5 has a limiting head 6. Figure 1 , 2The limiting head 6 (with the nut head in the middle) is larger than the size of the placement hole. The limiting head 6 is located above the connecting plate 3 to prevent the telescopic rod 5 from detaching from the placement hole. The tails of the two telescopic rods 5 are connected to the detection plate 9 via the mounting plate 4, thus connecting the tails of the telescopic rods 5 to the detection plate 9. A spring is fitted over the telescopic rod 5 between the mounting plate 4 and the connecting plate 3 on the detection plate 9. Thus, the telescopic rod 5 is hung on the placement hole via the limiting head 6, and the connection between the tails of the telescopic rods 5 and the detection plate 9 is achieved. The piston rod 2 of the electric cylinder 1 drives the detection plate 9 to move via the connecting plate 3 and the telescopic rods 5. When the downward movement of the detection plate 9 is obstructed, the telescopic rod 5 moves upward along the placement hole, compressing the spring outside the telescopic rod 5.

[0016] In order to limit the movement direction of the detection plate 9, two guide rods 7 are provided on the detection plate 9. Similarly, the guide rods 7 are connected to the detection plate 9 through the mounting plate 4. The guide rods 7 are covered with guide sleeves 8, which are fixedly installed on the bracket 10. The electric cylinder 1 can also be installed on the bracket 10.

[0017] like Figure 2 As shown, a proximity switch (not shown) is mounted on the connecting plate 3 via the mounting bracket 11, and a sensing element 12 corresponding to the proximity switch is mounted on the mounting plate 4. When the detection plate 9 moves downward, the positions of the connecting plate 3 and the mounting plate 4 are fixed. When the detection plate 9 touches an object and is obstructed, the spring is compressed, and the distance between the connecting plate 3 and the mounting plate 4 decreases. This causes a change in the position of the proximity switch and the sensing element 12, generating a signal. This signal controls the electric cylinder to stop moving.

[0018] During operation, the electric cylinder 1 drives the detection plate 9 downwards into the packaging box. After the detection plate 9 touches the item, the telescopic rod 5 moves upwards along the placement hole, compressing the outer spring of the telescopic rod 5. The proximity switch generates a signal, and the electric cylinder 1 stops. At this point, the height of the item inside the packaging box is obtained by subtracting the distance the detection plate 9 moves inside the packaging box from the depth of the packaging box.

[0019] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
