Description

Technical Field

[0001] This utility model relates to the field of edge-sealing machine technology, specifically to a quick-change and installation mechanism for the feed inlet of an automatic edge-sealing machine. Background Technology

[0002] Automatic edge-sealing machines are used in packaging production to seal the edges of products such as cartons and gift boxes. The feed inlet, as a key component for material entry into the equipment, needs to be frequently replaced depending on the product size. Its replacement efficiency and installation stability directly affect production pace and processing quality.

[0003] The feed inlets of existing automatic edge-sealing machines are mostly fixed to the frame with bolts. When replacing them, each bolt must be removed one by one, which is cumbersome and time-consuming. Especially in small-batch, multi-specification production, frequent replacements can lead to excessive downtime and seriously affect production efficiency. At the same time, the traditional installation structure lacks elastic buffer components. If the clamping is too tight, it can easily scratch the feed inlet; if it is too loose, it will cause shaking during feeding, affecting processing accuracy.

[0004] Furthermore, traditional feed inlets have a fixed height, which cannot be adjusted according to material thickness or equipment position, making it difficult to adapt to diverse production needs. This necessitates the customization of feed inlets of different heights, increasing production costs. Therefore, there is an urgent need for a feed inlet installation mechanism that enables quick replacement, stable clamping, and adjustable height to meet the demands of efficient and flexible production. In light of this, we propose a quick-change installation mechanism for the feed inlet of an automatic edge-sealing machine. Utility Model Content

For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0032] Please see Figure 1 - Figure 6 As shown, this utility model provides a technical solution:

[0033] An automatic edge-sealing machine feed inlet quick-change installation mechanism includes:

[0034] Mounting plate 1, with a feeding hopper 22 on the front side of mounting plate 1, and clamping mechanisms for clamping the feeding hopper 22 symmetrically fixed on the front side wall of mounting plate 1, and a lifting assembly for controlling the lifting and lowering of mounting plate 1 on the back side of mounting plate 1. The feeding hopper 22 is composed of a mounting base plate and a hopper body, and the mounting base plate and the hopper body are integrally formed.

[0035] In this embodiment, the clamping mechanism includes:

[0036] Support columns 2 are symmetrically fixedly installed on the front side wall of the mounting plate 1 near the edge. A clamping plate 3 is slidably installed between the two support columns 2. Slide grooves 4 are provided on the upper and lower surfaces of the clamping plate 3, on the side away from the support columns 2. A slider 5 is slidably installed in the slide grooves 4, and an insertion rod 6 is fixedly installed at the other end of the slider 5. A limiting component is provided on the mounting plate 1 to constrain the insertion rod 6, and a clamping component is provided on the clamping plate 3 to clamp the mounting base plate of the feed hopper 22. The support columns 2 provide sliding support for the clamping plate 3, allowing the clamping plate 3 to be adjusted laterally along the support columns 2 to accommodate feed hoppers 22 of different sizes. The sliding engagement of the slide grooves 4 and slider 5 can drive the insertion rod 6 to move synchronously, facilitating the insertion rod 6 to engage or disengage with the limiting component, achieving rapid locking and unlocking of the clamping mechanism. The clamping component further enhances the stability of the feed hopper 22 after installation, preventing loosening.

[0037] In this embodiment, the limiting component includes:

[0038] Slot 7 is located on the front sidewall of mounting plate 1. A mounting groove 8 is formed on the inner top surface of slot 7, and a through groove 9, communicating with the outside, is formed on the inner top surface of mounting groove 8. A pull rod 10 is inserted into the through groove 9, with its bottom end extending into slot 7. A limiting block 11 is fixedly installed at the bottom end of pull rod 10, engaging with insert rod 6. Slot 7 provides insertion space for insert rod 6. Pull rod 10 can drive limiting block 11 to move up and down along through groove 9. When limiting block 11 descends and engages with insert rod 6, it restricts the lateral movement of insert rod 6, thereby fixing the position of clamping plate 3. Conversely, lifting pull rod 10 separates limiting block 11 from insert rod 6, releasing the constraint. The operation is convenient and requires no tools.

[0039] In this embodiment, a spring 12 is installed in the mounting groove 8 and directly above the limiting block 11. The pull rod 10 is inserted into the spring 12. The spring 12 can apply a downward elastic force to the limiting block 11, ensuring that the limiting block 11 is stably engaged with the insert rod 6, and preventing the limiting block 11 from disengaging from the insert rod 6 due to vibration during equipment operation. At the same time, the elastic potential energy of the spring 12 can be stored when the pull rod 10 is lifted, and the limiting block 11 will automatically reset after the pull rod 10 is released, simplifying the operation process.

[0040] In this embodiment, the clamping component includes:

[0041] A threaded groove 13 is formed on the clamping plate 3. A clamping knob 14 is threadedly installed inside the threaded groove 13. A buffer pad 15 is fixedly installed at the end of the clamping knob 14 near the mounting plate 1. A spring 16 is provided between the buffer pad 15 and the inner wall of the clamping plate 3, and the spring 16 is inserted into the clamping knob 14. The buffer pad 15 is made of soft rubber. The threaded engagement between the clamping knob 14 and the threaded groove 13 can adjust the position of the buffer pad 15 so that it fits tightly against the mounting base plate of the feed hopper 22. The spring 16 can buffer the tightening force of the clamping knob 14 to avoid excessive compression and damage to the feed hopper 22. The soft rubber buffer pad 15 can increase friction and prevent scratching the surface of the feed hopper 22 during clamping.

[0042] In this embodiment, the lifting assembly includes:

[0043] A lifting arm 17 is mounted on the back side of the mounting plate 1. A lifting groove is formed on the front side wall of the lifting arm 17, and a threaded rod 18 is rotatably mounted within the lifting groove. A threaded block 19 is threadedly connected to the threaded rod 18, and the threaded block 19 slides within the lifting groove. The other side of the threaded block 19 is fixed to the mounting plate 1. A motor 20 is fixedly mounted at the top of the lifting arm 17, and the output shaft of the motor 20 is coaxially connected to the threaded rod 18. A bearing seat 21 is fixedly mounted at the bottom of the lifting groove, and the threaded rod 18 is coaxially connected to the bearing seat 21. The motor 20 drives the threaded rod 18 to rotate, and the threaded engagement between the threaded rod 18 and the threaded block 19 causes the mounting plate 1 to move up and down along the lifting groove, thereby adjusting the height of the feed hopper 22 to accommodate different material specifications. The bearing seat 21 provides bottom support for the threaded rod 18, reducing radial runout during rotation and ensuring smooth lifting.

[0044] In this embodiment, multiple fixing bolts are symmetrically fixed to the side wall of the lifting arm 17. The fixing bolts can stably install the lifting arm 17 on the frame of the edge-sealing machine, prevent the lifting arm 17 from shaking during the lifting process, enhance the stability of the overall structure, and ensure the positional accuracy of the feed hopper 22 after height adjustment.

[0045] When using the quick-change installation mechanism for the automatic edge-sealing machine feed inlet in this embodiment:

[0046] When replacing the feed hopper 22, first lift the pull rod 10 upwards. The pull rod 10 compresses the spring 12 and drives the limit block 11 to rise, so that the limit block 11 separates from the insertion rod 6 and releases the limit. Then push the clamping plate 3 to slide along the support column 2, so that the slider 5 moves in the slide groove 4, increasing the gap between the clamping plate 3 and the mounting plate 1. Then loosen the tightening knob 14 so that the buffer pad 15 is disengaged from the mounting base plate of the feed hopper 22, and the old feed hopper 22 can be removed.

[0047] When installing the new feed hopper 22, place it between the mounting plate 1 and the clamping plate 3, and push the clamping plate 3 along the support column 2 to slide it to a suitable position so that the mounting base of the feed hopper 22 fits against the front side wall of the mounting plate 1; then tighten the clamping knob 14, which pushes the buffer pad 15 to press against the mounting base, and the spring 16 is compressed to generate elastic force to enhance the fit; finally, release the pull rod 10, and the spring 12 resets to drive the limit block 11 to descend, engaging with the insertion rod 6 to fix the position of the clamping plate 3, thus completing the installation. If height adjustment is required, start the motor 20, and the threaded rod 18 rotates, driving the threaded block 19 and the mounting plate 1 to move up and down, so that the feed hopper 22 is in the optimal feeding position.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
