Description

Technical Field

[0001] This utility model relates to the field of packaging box embossing equipment, specifically a printing and embossing device for wine packaging boxes. Background Technology

[0002] In the production of wine packaging boxes, it is often necessary to emboss the surface of the box lid. In existing embossing equipment, when embossing the rectangular box lid surface of wine packaging boxes, a lower module is usually set on the pressure seat below the upper template, and the external dimensions of the lower module are adapted to the internal dimensions of the box lid. When in use, the box lid is placed on the lower module, and then the upper template is pressed down to achieve the embossing operation. After the pressing is completed, the box lid is manually removed from the lower module.

[0003] During the process of removing the box lid, because the outer dimensions of the lower module are compatible with the inner dimensions of the box lid, and the box lid fits tightly with the lower module after being pressed down by the upper template, it is necessary to reach between the upper template and the lower module to forcefully pull the box lid off the lower module when manually removing the box lid. In this process, even if both hands are used to pull it off, the box lid may be damaged, affecting product quality and production efficiency. At the same time, when pulling upwards, the hand is likely to hit the upper template, which poses a safety hazard. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a printing and embossing device for wine packaging boxes.

[0005] The technical solution of this utility model is as follows:

[0006] A printing and embossing device for wine packaging boxes includes a main body and a pressure seat on it. The pressure seat is provided with a lower module, the outer ring of which is adapted to the inner cavity of the box lid to be processed, and an upper template that can be vertically lifted and lowered is also provided above it.

[0007] As the core technical concept of this utility model, the embossing device also includes an ejector assembly. The ejector assembly includes movable blocks that are vertically and elastically disposed on opposite sides of the lower module, and an ejector plate disposed on the upper side of the movable blocks. The ejector plate includes a vertical plate that is spaced apart from the outer wall of the lower module, and a horizontal plate that is horizontally disposed between the vertical plate and the lower module. The lower side of the horizontal plate is connected to the movable block, and the upper side is lower than the lower module.

[0008] Furthermore, the ejector plate is a ring structure set along the outer ring of the lower module.

[0009] Furthermore, the lower module has a vertical groove corresponding to the movable block. The upper side of the outer end of the movable block is connected to the top plate, and the inner end is inserted into the groove and slides vertically with the groove. The groove also has an elastic element that vertically and elastically abuts against the lower side of the movable block.

[0010] Specifically, the chute includes a first vertical groove and a second vertical groove that are connected to each other. The second vertical groove is located inside the first vertical groove and its width is greater than that of the first vertical groove. The elastic element is vertically disposed in the second vertical groove.

[0011] Preferably, the elastic element is a cylindrical helical compression spring.

[0012] More preferably, at least four sets of sliding blocks and corresponding slide rails are arranged around the lower module.

[0013] Furthermore, the lower module has a mounting groove on its lower side that communicates with the second vertical groove, and a sealing plate is detachably connected inside the mounting groove.

[0014] Preferably, the thickness of the sealing plate is less than the depth of the mounting groove.

[0015] More preferably, the four corners of the lower module are rounded.

[0016] The ejector plate of this utility model provides support and guidance for the installation of the box cover. Specifically, the gap between the vertical plate of the ejector plate and the lower module can be adapted to the thickness of the edge of the box cover, and the upper side of the horizontal plate is lower than the lower module, which can ensure that the lower part of the box cover can be accurately fitted into the upper part of the lower module. At the same time, with the vertically elastic movable block, after the embossing is completed, the box cover can be moved smoothly upward with the ejector plate under the action of elastic force, thereby realizing the easy removal of the box cover, which can avoid damage to the box cover and avoid the safety hazards of the removal operation.

[0025] Combination Figure 1 This embodiment provides a printing and embossing device for wine packaging boxes, including a device body 1 and a pressure seat 2 on it. The pressure seat 2 is provided with a lower module 3. The outer ring of the lower module 3 is adapted to the inner cavity of the box cover 9 to be processed, and an upper template 4 that can be vertically lifted is also provided above it.

[0026] Among them, the upper template 4 is hydraulically controlled for lifting. It, along with the main body 1, the pressure seat 2, and the lower module 3, are the main components of existing commercially available embossing devices. Their specific structure and working principle will not be described in detail here.

[0027] Combination Figure 2 and Figure 3 The embossing device also includes an ejector assembly, which includes movable blocks 5 vertically and elastically disposed on opposite sides of the lower module 3, and an ejector plate 6 disposed on the upper side of the movable blocks 5. The ejector plate 6 includes a vertical plate with a gap between it and the outer wall of the lower module 3, and a horizontal plate horizontally disposed between the vertical plate and the lower module 3. The lower side of the horizontal plate is connected to the movable blocks 5, and the upper side is lower than the lower module 3, which provides stable support for the box cover 9 to be processed without affecting the fitting accuracy during embossing.

[0028] Preferably, the height of the upper side of the horizontal plate is 3mm-5mm lower than the upper side of the lower module 3. This height setting can provide stable support for the box cover 9 to be processed, ensuring accurate positioning when the box cover 9 is placed, and will not affect the tight fit between the box cover and the lower module 3 during embossing, ensuring embossing accuracy. At the same time, after embossing is completed, it can cooperate with the lifting and resetting of the ejector plate 6, making it easy for the operator to remove the box cover from the lower module 3.

[0029] Combination Figure 2 and Figure 3 The lower module 3 has a vertical groove corresponding to the movable block 5. The groove has a T-shaped cross section. The upper side of the outer end of the movable block 5 is connected to the ejector plate 6, and the inner end is inserted into the groove and slides vertically with the groove to ensure that the movable block 5 rises and falls smoothly without jamming. The groove is also equipped with an elastic element 7 that is vertically elastic and presses against the lower side of the movable block 5 to provide an upward ejection force for the ejector plate 6.

[0030] Specifically, the slide groove runs through the lower side of the lower module 3. In use, the inner end of the movable block 5 is inserted into the slide groove from the lower side of the lower module 3. The slide groove includes a first vertical groove 31 and a second vertical groove 32 that are connected. The second vertical groove 32 is located inside the first vertical groove 31 and its width is greater than that of the first vertical groove 31. The elastic member 7 is vertically arranged in the second vertical groove 32 to prevent the elastic member 7 from tilting when it is compressed.

[0031] The elastic element 7 is a cylindrical helical compression spring, which has good elastic recovery and fatigue resistance, can stably provide continuous ejection force, and is simple in structure, low in cost, and easy to replace, meeting the needs of long-term high-frequency use of the device. For example, commonly used cylindrical helical compression springs are made of 65Mn spring steel with a wire diameter of 2mm, an outer diameter of 22mm, and a free length of 40mm to ensure that sufficient ejection force is provided.

[0032] Combination Figure 4 The lower module 3 has an installation groove 33 on its lower side that communicates with the second vertical groove 32. A sealing plate 8 is detachably connected to the installation groove 33 by means of an internal hex bolt, which facilitates the installation and removal of the cylindrical helical compression spring in the second vertical groove 32.

[0033] The thickness of the sealing plate 8 is less than the depth of the mounting groove 33. A shim can be added between the bottom of the mounting groove 33 and the sealing plate 8 to facilitate the adjustment of the preload of the cylindrical helical compression spring after long-term use.

[0034] Combination Figure 5 The ejector plate 6 is a ring structure set along the outer ring of the lower module 3. It is rectangular in shape and matches the shape of the lower module 3. It can apply a uniform ejection force to the four edges of the lid at the same time, so that the lid is balanced and will not tilt during the ejection process.

[0035] Combination Figure 5 The movable block 5 and the corresponding first vertical groove 31, second vertical groove 32 and mounting groove 33 are arranged in four groups around the lower module 3, respectively located at the midpoint of the four sides of the lower module 3, to provide balanced support for the annular top plate 6, ensure that the top plate 6 is subjected to uniform force, avoid the top plate 6 tilting or the box cover deforming due to excessive local force, and ensure that the top process is stable and reliable.

[0036] Combination Figure 5 The four corners of the lower module 3 are rounded, which can prevent the lid from being scratched by sharp edges when it is put on or taken off, protect the integrity of the lid, reduce the risk of operators being scratched by sharp edges, and improve operational safety.

[0037] In use, the upper template 4 is raised above the lower module 3. Then, the lower edge of the box cover 9 to be processed is manually inserted into the gap between the vertical plate and the outer wall of the lower module 3. Preferably, this gap is 0.1mm-0.3mm larger than the thickness of the lower edge of the box cover 9. At this time, the lower edge of the box cover 9 is fitted onto the upper outer ring of the lower module 3, and the lower side of the box cover abuts against the horizontal plate. Embossing begins. The upper template 4 descends, and after the lower side plane of the upper template 4 contacts the upper side of the box cover, it continues to press down, pushing the box cover and the ejector plate 6 vertically downwards along the lower module 3. The movable block 5 slides down in the groove with the ejector plate 6. The elastic element 7 is compressed by the pressure of the movable block 5. The box cover completes the embossing operation through the pressure between the upper template 4 and the lower module 3. After embossing, the upper template 4 rises and resets. Under the action of the elastic force released by the elastic element 7, the movable block 5 drives the ejector plate 6 upwards, pushing the edge of the box cover upwards synchronously. The box cover returns to its initial position with the ejector plate 6, and then the operator can easily remove the box cover. Compared to existing technologies, this method eliminates the need for manual force to remove the lid, thus avoiding the safety hazard of hand impact on the template 4 and preventing damage to the lid due to uneven force, significantly improving production efficiency and operational safety.
