Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box processing equipment, and in particular to a device for storing and replacing waste ejector pins in cardboard box processing. Background Technology

[0002] Waste removal ejector pins are tools used in cardboard box manufacturing to remove waste material generated after die-cutting of cardboard. During cardboard box manufacturing, the die-cutting process produces unwanted parts, or waste, which need to be removed to obtain a complete cardboard box shape. Waste removal ejector pins play a crucial role in this process. They typically have a sharp head to insert into the waste material at the die-cut opening. Some ejector pins may also have barbs integrated into the top, allowing them to pull the waste material off after insertion, thus achieving waste removal.

[0003] In some existing cardboard box processing waste removal thimble storage and replacement devices, the layout of the storage trays is often not carefully designed. They are simply stacked or arranged without considering the viewing angle and operating space for retrieving the waste removal thimbles. For example, the storage trays may be placed parallel to each other at equal intervals. When viewed from above, the upper storage trays will largely obscure the lower storage trays, making it difficult for operators to directly see the waste removal thimbles on the lower storage trays. This spatial layout creates a large number of blind spots, requiring operators to constantly adjust their body posture or move the device to see the obscured parts when retrieving or placing waste removal thimbles. To improve this, a cardboard box processing waste removal thimble storage and replacement device is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste removal pin storage and replacement device for cardboard box processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste removal pin storage and replacement device for cardboard box processing includes a column, a mounting groove on the column, a plurality of mounting blocks in the mounting groove, two extrusion grooves on the outer wall of each mounting block, a positioning rod in each extrusion groove via an extrusion mechanism, a plurality of positioning holes corresponding to the positioning rods on the outer wall of the column, a connecting groove on the mounting block, a rotating ring in the connecting groove via a limiting mechanism, and a storage tray fixedly mounted on the outer wall of the rotating ring.

[0007] Preferably, the extrusion mechanism includes a spring disposed in the extrusion groove, and the two ends of the spring are elastically connected to the outer wall of the positioning rod and the inner wall of the extrusion groove, respectively.

[0008] Preferably, the limiting mechanism includes a limiting ring fixedly disposed on the upper and lower end faces of the rotating ring, and the upper and lower inner walls of the connecting groove are provided with limiting grooves corresponding to the limiting rings.

[0009] Preferably, both the mounting groove and the mounting block have a T-shaped cross-section, and a stabilizing plate is fixedly provided on the bottom wall of the column.

[0010] Preferably, each of the rotating rings has two storage trays fixed to its outer wall, and the two storage trays are distributed at equal intervals around the circumference of the rotating ring.

[0011] Preferably, the four storage trays, corresponding to each other, are arranged in a cross shape, and the positioning holes on the outer wall of the column are evenly spaced vertically.

[0012] Preferably, the rotating ring has an annular inner groove on its arc-shaped inner wall, and a rubber ring is provided in the annular inner groove, the surface of which is rough.

[0013] The beneficial effects of this utility model are:

[0014] 1. Multiple storage trays are staggered, ensuring that the waste removal pins in the lower storage tray are not obstructed by the upper storage tray, making it convenient for operators to retrieve and place the waste removal pins. This design fully considers operational convenience and improves work efficiency.

[0015] 2. Multiple storage trays allow for the categorized storage of waste ejector pins, ensuring orderly storage and facilitating retrieval. Operators can quickly locate the required waste ejector pins.

[0016] 3. By pressing the positioning rod, it can be disengaged from the positioning hole, releasing the fixed installation of the mounting block and enabling convenient disassembly of the rotating ring and storage tray. This is highly beneficial for the maintenance, repair, or cleaning of the storage tray, reducing the difficulty of operation.

[0017] 4. The positioning holes corresponding to the positioning rods can be replaced to adjust the distance between the upper and lower storage trays, which enhances the flexibility of the device. The storage space can be adjusted according to factors such as the length and type of the waste removal pins in actual use, ensuring the convenience of using the device.

[0018] 5. The horizontal position of the storage trays can be adjusted by rotating the rotating ring relative to the column. Multiple storage trays can be rotated and adjusted according to actual needs, making it more convenient for operators to use. This adjustability can meet the usage habits of different operators and the requirements for retrieving waste ejector pins in different working scenarios. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-4

[0026] A waste removal pin storage and replacement device for cardboard box processing includes a column 1, an installation groove 2 on the column 1, a plurality of installation blocks 3 in the installation groove 2, two extrusion grooves 7 on the outer wall of each installation block 3, a positioning rod 8 in each extrusion groove 7 through an extrusion mechanism, a plurality of positioning holes 4 corresponding to the positioning rods 8 on the outer wall of the column 1, a connecting groove 10 on the installation block 3, a rotating ring 5 in the connecting groove 10 through a limiting mechanism, and a storage tray 6 fixedly mounted on the outer wall of the rotating ring 5.

[0027] The extrusion mechanism includes a spring 9 disposed within the extrusion groove 7. Both ends of the spring 9 are elastically connected to the outer wall of the positioning rod 8 and the inner wall of the extrusion groove 7, respectively. The elastic potential energy provided by the spring 9 enables the positioning rod 8 to be extruded from the extrusion groove 7 and inserted into the corresponding positioning hole 4, thus achieving stable installation of the mounting block 3 within the mounting groove 2.

[0028] The limiting mechanism includes a limiting ring 12 fixedly disposed on the upper and lower end faces of the rotating ring 5, and limiting grooves 11 corresponding to the limiting ring 12 are provided on the upper and lower inner walls of the connecting groove 10. The limiting ring 12 is located in the limiting groove 11, which effectively prevents the rotating ring 5 from moving relative to the mounting block 3 and ensures the stability of the connection between the two.

[0029] Both the mounting slot 2 and the mounting block 3 have a T-shaped cross-section, and a stabilizing plate is fixed to the bottom wall of the column 1. This stabilizing plate ensures the stability of the column 1 and other components when placed on the ground.

[0030] Each rotating ring 5 has two storage trays 6 fixed to its outer wall, with the two storage trays 6 evenly spaced circumferentially relative to the rotating ring 5. The four corresponding storage trays 6 are staggered in a cross shape, and the positioning holes 4 on the outer wall of the column 1 are evenly spaced vertically. The above-mentioned circumferential and vertically even spacing, as well as the staggered cross distribution, ensure that there is no interference between the multiple storage trays 6.

[0031] The rotating ring 5 has an annular inner groove 13 on its arc-shaped inner wall, and a rubber ring 14 is provided inside the annular inner groove 13. The surface of the rubber ring 14 is roughened. The rubber ring 14 is provided and its surface is roughened to ensure friction and to ensure that the rotating ring 5 cannot be rotated relative to the column 1 to adjust its horizontal position without the intervention of external force.

[0032] When using this utility model, such as Figure 1 As shown, multiple storage trays 6 are staggered to ensure that the waste removal pins in the lower storage tray 6 are not blocked by the upper storage tray 6, thus ensuring the convenience of retrieval and placement. In addition, multiple storage trays 6 can store waste removal pins that have been sorted, and the orderly storage makes it easy to retrieve and place them.

[0033] In this solution, pressing the positioning rod 8 inside the positioning hole 4 causes the positioning rod 8 to move and compress the spring 9, disengaging from the positioning hole 4 and entering the compression groove 7. This releases the fixed installation of the mounting block 3 in the mounting groove 2, enabling the installation and release operations of the mounting block 3 relative to the column 1 and the mounting groove 2, and facilitating the convenient disassembly of the rotating ring 5 and the storage tray 6.

[0034] Alternatively, the positioning hole 4 corresponding to the positioning rod 8 can be replaced to adjust the distance between the upper and lower storage trays 6, ensuring the ease of use of the device.

[0035] In this solution, the horizontal position of the storage tray 6 can be adjusted relative to the column 1 by simply rotating the rotating ring 5. Multiple storage trays 6 can be rotated and adjusted to adjust their horizontal position according to actual needs, which is more convenient for operators to use.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
