Description

Technical Field

[0001] This utility model relates to the technical field of packaging box forming, specifically to a wine box bubble pressing mold. Background Technology

[0002] 2. During the assembly of the wine box, the face paper is first coated with adhesive. Then, the adhesive-coated face paper is folded and bonded to the corrugated paper (also known as wainscoting). Next, the bubble-pressing process begins. In this process, the bonded wine box is placed into an inner mold that matches the shape of the box's interior. Simultaneously, an outer mold that matches the outer contour of the box is used. The inner and outer molds work together to apply pressure, firmly pressing the bonded areas of the wine box to ensure the adhesive dries completely and bonds securely. Furthermore, this bubble-pressing process, by applying pressure, expels air from the adhesive layer, effectively removing any air bubbles that may be present at the bonded areas, keeping the bonded surfaces of the wine box smooth and wrinkle-free, thereby improving the overall aesthetics and durability of the wine box.

[0003] 3. In wine box design, to enhance the product's visual appeal and brand recognition, three-dimensional patterns, text, or other three-dimensional decorative elements are often added to the surface of the wine box. However, the outer mold of the bubble wrap mold is usually flat. When there are three-dimensional elements on the surface of the wine box, the outer mold cannot completely adhere to the surface of these three-dimensional elements, resulting in insufficient pressure on the three-dimensional elements and the surrounding area. This leads to poor adhesion around the three-dimensional elements and the presence of air bubbles. Utility Model Content

[0004] The present invention relates to four utility models that aim to provide a wine box pressing mold that can avoid dust generation and waste of sand and gravel raw materials.

[0005] 5. To achieve the above objectives, the present invention adopts the following technical solution:

[0006] 61) A wine box foam pressing mold, including an inner mold, the inner mold being matched with the inner cavity of the wine box in size, and an outer mold matching the size of each side of the inner mold being provided on the outer side of each outer mold facing the inner mold. An elastic membrane is provided on the side of each outer mold facing the inner mold, and an inflation gap is formed between the elastic membrane and the outer mold. Each outer mold is provided with a gas channel communicating with the inflation gap, and each gas channel is connected to an inlet and outlet gas adjustment device for inflating and deflating the inflation gap.

[0007] In these seven utility models, the inner mold is matched to the inner cavity of the wine box in size, ensuring that the wine box is subjected to uniform pressure during the pressing process. This avoids localized stress concentration during pressing, thus preventing problems such as deformation, twisting, or dimensional deviation. Each side of the inner mold has an outer mold of matching size, ensuring that each side of the wine box is subjected to uniform pressure during pressing. This ensures that the bonded areas on each side are tightly pressed, and that the adhesive dries fully and bonds firmly.

[0008] The three-dimensional elements on the surface of the wine box create an uneven surface, resulting in gaps between the outer mold and the box surface during the pressing process. To address this issue, each outer mold has an elastic membrane on its side facing the inner mold, forming an air gap between the membrane and the outer mold. By inflating this gap, the elastic membrane expands and adheres tightly to the box surface, filling the gap between the outer mold and the box surface. This ensures uniform pressure on the three-dimensional elements and their surrounding area, resulting in tight compaction and promoting thorough drying and strong adhesion of the adhesive. Simultaneously, air bubbles may exist at the bonded areas in the gaps between the outer mold and the box surface; the expansion of the elastic membrane fills these gaps, effectively eliminating air bubbles. After pressing, the air gaps are evacuated, causing the elastic membrane to gradually shrink and separate from the box surface, facilitating subsequent operations.

[0009] 92) According to 1), the wine box pressing mold is obtained, wherein:

[0010] 10 The gas channel includes an inflation channel and an exhaust channel. The inflation channel is arranged perpendicular to the surface of the outer mold and communicates with the inflation gap. A first one-way valve is provided on the inflation channel and is located near the inflation gap.

[0011] The air extraction channel 11 is arranged perpendicular to the surface of the outer mold and is connected to the inflation gap. A second one-way valve is provided on the air extraction channel, and the second one-way valve is located near the inflation gap.

[0012] In these 12 utility models, the gas passage includes an inflation channel and an extraction channel, facilitating the inflation and extraction of gas into the inflation gap, thereby allowing the elastic membrane to adhere to and separate from the surface of the wine box. The inflation and extraction channels are respectively arranged perpendicular to the surface of the outer mold. This arrangement minimizes the area occupied by the inflation and extraction channels within the outer mold, preventing instability and uneven pressure in the outer mold structure caused by their large distribution within the mold. This avoids deformation or damage to the outer mold during the pressing process. A first one-way valve is provided on the inflation channel near the inflation gap to prevent gas from flowing back into the inflation channel during or after inflation. Simultaneously, a second one-way valve is provided on the extraction channel near the inflation gap to prevent gas from flowing into the extraction channel during and after inflation. By setting the first and second one-way valves, the gas pressure in the inflation gap can be maintained stable during the pressing process, thus maintaining the pressing effect.

[0013] 133) According to 1), the wine box pressing mold is obtained, wherein:

[0014] 14 The inlet and outlet gas regulating device includes a vacuum pump and an air pump. The inlet of the vacuum pump is connected to the gas extraction channel in the gas channel through a first hose. The gas extraction channel is provided with a second one-way valve near the inflation gap. The outlet of the air pump is connected to the inflation channel in the gas channel through a second hose. The inflation channel is provided with a first one-way valve near the inflation gap.

[0015] In these 15 utility models, the air pump's outlet is connected to the inflation channel, used to inject gas into the inflation gap, ensuring a tight fit between the elastic membrane and the wine box surface, thus maintaining the pressing effect. The vacuum pump's inlet is connected to the extraction channel, used to extract gas from the inflation gap, thereby separating the elastic membrane from the wine box. A first one-way valve is provided on the inflation channel near the inflation gap to prevent gas from flowing back into the inflation channel during or after inflation. Simultaneously, a second one-way valve is provided on the extraction channel near the inflation gap to prevent gas from flowing into the extraction channel during and after inflation. By setting the first and second one-way valves, the gas pressure in the inflation gap can be kept stable during the pressing process, thus maintaining the pressing effect.

[0016] 16. According to 1), the wine box pressing mold is obtained, wherein:

[0017] 17 also includes a support frame, on which are provided several telescopic pumps for pushing the outer mold to move towards the inner mold. The position of each telescopic pump corresponds one-to-one with the outer mold, and the telescopic rod of each telescopic pump is fixedly connected to the side of the outer mold away from the elastic membrane.

[0018] In the 18 utility models, a telescopic pump is provided on the bracket. The telescopic rod of the telescopic pump is fixedly connected to the side of the outer mold away from the elastic membrane. Through the telescopic action of the telescopic pump, the outer mold can be pushed to move towards the inner mold, so that the outer mold and the inner mold can fit tightly together, thereby applying pressure to the wine box between the outer mold and the inner mold.

[0019] 19. According to 1), the wine box pressing mold is obtained, wherein:

[0020] 20 The outer surface of the inner mold is provided with a sponge layer, the thickness of which is 1mm.

[0021] In this invention, the outer surface of the inner mold is provided with a sponge layer, which can form a flexible contact surface between the inner mold and the wine box, thereby reducing friction between the inner mold and the inner surface of the wine box and preventing wear on the inner surface of the wine box. The sponge layer is 1mm thick, which allows the wine box to fit smoothly onto the inner mold without being unable to fit due to the sponge layer.

[0022] 22. Compared with the prior art, the present invention also has the following technical effects:

[0023] In this invention, each side of the inner mold is provided with an outer mold that matches its size. Each outer mold has an elastic membrane on its side facing the inner mold, forming an air gap between the elastic membrane and the outer mold. By inflating the air gap, the elastic membrane expands and adheres tightly to the surface of the wine box, filling the gap between the outer mold and the wine box surface. This ensures that the three-dimensional element and its surrounding area are evenly compressed, promoting thorough drying and strong adhesion of the adhesive. Simultaneously, air bubbles may exist at the bonding area in the gap between the outer mold and the wine box surface; the expansion of the elastic membrane fills the gap, effectively eliminating air bubbles.

[0025] 25 Figure 2 This is a top view of the inner mold and outer mold in the wine box foam pressing mold of this utility model.

[0026] 26 Figure 3 This is a cross-sectional view of the outer mold in the wine box foam pressing mold of this utility model. Detailed Implementation

[0027] 27. The following detailed description, through specific implementation methods, further illustrates the following:

[0028] The reference numerals in the accompanying drawings of the instruction manual include: inner mold 1, outer mold 2, elastic membrane 3, inflation gap 4, inflation channel 5, air extraction channel 6, first one-way valve 7, second one-way valve 8, vacuum pump 9, air pump 10, and telescopic pump 11.

[0029] 29 Examples, see Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the wine box foam pressing mold includes an inner mold 1, which is matched with the size of the inner cavity of the wine box. Each side of the inner mold 1 is provided with an outer mold 2 that matches its size. Each outer mold 2 is provided with an elastic membrane 3 on the side facing the inner mold 1. An inflation gap 4 is formed between the elastic membrane 3 and the outer mold 2. Each outer mold 5 is provided with a gas channel communicating with the inflation gap 4. Each gas channel is connected to an inlet and outlet gas adjustment device for inflating and deflating the inflation gap.

[0030] In this embodiment, the inner mold 1 is matched with the inner cavity of the wine box, which ensures that the wine box is subjected to uniform pressure during the pressing process, avoiding local stress concentration and thus preventing deformation, twisting, or dimensional deviation. Each side of the inner mold 1 is provided with an outer mold 2 that matches its size, ensuring that each side of the wine box is subjected to uniform pressure during the pressing process, thereby ensuring that the bonding areas on each side are tightly pressed, and that the adhesive dries fully and bonds firmly.

[0031] The three-dimensional elements on the surface of the wine box cause unevenness, resulting in gaps between the outer mold 2 and the wine box surface during the pressing process. To solve this problem, each outer mold 2 has an elastic membrane 3 on its side facing the inner mold 1, forming an air gap 4 between the elastic membrane 3 and the outer mold 2. By inflating the air gap 4, the elastic membrane 3 expands and can fit tightly against the wine box surface, filling the gap between the outer mold and the wine box surface. This ensures that the three-dimensional elements and their surrounding areas are evenly compressed, promoting thorough drying and strong adhesion of the adhesive. Simultaneously, air bubbles may exist at the bonding points in the gaps between the outer mold 2 and the wine box surface; the expansion of the elastic membrane 3 fills these gaps, effectively eliminating air bubbles. After pressing, the air gap 4 is evacuated, causing the elastic membrane 3 to gradually shrink and separate from the wine box surface, facilitating subsequent operations.

[0032] See 32 Figure 3 As shown, the gas passage includes an inflation channel 5 and an exhaust channel 6. The inflation channel 5 is arranged perpendicular to the surface of the outer mold 2 and is connected to the inflation gap 4. A first one-way valve 7 is provided on the inflation channel 5 and is located near the inflation gap 4. The exhaust channel 6 is arranged perpendicular to the surface of the outer mold 2 and is connected to the inflation gap 4. A second one-way valve 8 is provided on the exhaust channel 6 and is located near the inflation gap 4.

[0033] 33. In this embodiment, the gas channel includes an inflation channel 5 and an extraction channel 6, facilitating the inflation and extraction of gas into the inflation gap 4, thereby allowing the elastic membrane 3 to adhere to and separate from the surface of the wine box. The inflation channel 5 and the extraction channel 6 are respectively arranged perpendicular to the surface of the outer mold 2. This arrangement minimizes the area occupied by the inflation channel 5 and the extraction channel 6 on the outer mold 2, preventing structural instability and uneven pressure in the outer mold 2 caused by the large area distribution of the inflation channel 5 and the extraction channel 6 inside the outer mold 2. This avoids deformation or damage to the outer mold 2 during the pressing process. However, when one end of the inflation channel 5 and the extraction channel 6 is located on the side of the inflation gap 4, the ends of the inflation channel and the extraction channel will move when the outer mold presses against the inner mold, causing instability in the connection of the inflation channel and the extraction channel. At the same time, this will hinder the pressing process of the outer mold against the inner mold and prevent gas from smoothly entering the inflation gap, thus affecting the entire pressing process.

[0034] A first one-way valve 7 is installed on the inflation channel 5 near the inflation gap 4 to prevent gas from flowing back into the inflation channel 5 during or after inflation. Simultaneously, a second one-way valve 8 is installed on the suction channel 6 near the inflation gap 4 to prevent gas from flowing into the suction channel 6 during and after inflation. By setting the first one-way valve 7 and the second one-way valve 8, the gas pressure in the inflation gap 4 can be kept stable during the pressing process, thereby maintaining the pressing effect.

[0035] 35 Secondly, the inlet and outlet gas regulating device includes a vacuum pump 9 and an air pump 10. The air inlet of the vacuum pump 9 is connected to the gas extraction channel 6 in the gas channel through a first hose. The gas extraction channel 6 is provided with a second one-way valve 8 near the inflation gap 4. The air outlet of the air pump 10 is connected to the inflation channel 5 in the gas channel through a second hose. The inflation channel 5 is provided with a first one-way valve 7 near the inflation gap 4.

[0036] 36. In this embodiment, the outlet of the air pump 10 is connected to the inflation channel 5 to inject gas into the inflation gap 4, so that the elastic membrane 3 fits tightly against the surface of the wine box, thereby maintaining the pressing effect. The inlet of the vacuum pump 9 is connected to the extraction channel 6 to extract the gas from the inflation gap, thereby separating the elastic membrane 3 from the wine box. A first one-way valve 7 is provided on the inflation channel 5 near the inflation gap 4 to prevent gas from flowing back into the inflation channel during or after inflation. At the same time, a second one-way valve 8 is provided on the extraction channel 6 near the inflation gap 4 to prevent gas from flowing into the extraction channel 6 during and after inflation. By setting the first one-way valve 7 and the second one-way valve 8, the gas pressure in the inflation gap 4 can be kept stable during the pressing process, thereby maintaining the pressing effect.

[0037] 37 also includes a support frame, on which are provided several telescopic pumps 11 for pushing the outer mold 2 to move towards the inner mold 1. The position of each telescopic pump 11 corresponds one-to-one with the outer mold 2, and the telescopic rod of each telescopic pump 11 is fixedly connected to the side of the outer mold 2 away from the elastic membrane.

[0038] 38 In this embodiment, a telescopic pump 11 is provided on the bracket. The telescopic rod of the telescopic pump 11 is fixedly connected to the side of the outer mold 2 away from the elastic membrane 3. Through the telescopic action of the telescopic pump 11, the outer mold 2 can be pushed to move towards the inner mold 1, so that the outer mold 2 and the inner mold 1 can fit tightly together, thereby applying pressure to the wine box between the outer mold 2 and the inner mold 1.

[0039] 39. In addition, the outer surface of the inner mold 1 is provided with a sponge layer, the thickness of which is 1mm. In this embodiment, the sponge layer on the outer surface of the inner mold 1 can form a flexible contact surface between the inner mold 1 and the wine box, which can reduce the friction between the inner mold 1 and the inner surface of the wine box, thereby avoiding wear on the inner surface of the wine box caused by the inner mold 1. The 1mm thickness of the sponge layer allows the wine box to fit smoothly onto the inner mold 1 without being unable to fit properly due to the sponge layer.

[0040] 40. In this embodiment, each side of the inner mold 1 is provided with an outer mold 2 that matches its size. Each outer mold 2 has an elastic membrane 3 on its side facing the inner mold 1, forming an inflation gap 4 between the elastic membrane 3 and the outer mold 2. By inflating the inflation gap 4, the elastic membrane 3 expands and can fit tightly against the surface of the wine box, filling the gap between the outer mold and the surface of the wine box. This ensures that the three-dimensional element and its surrounding area are uniformly compressed, allowing the three-dimensional element and its surrounding area to be tightly compacted, thereby promoting the full drying and firm bonding of the adhesive. At the same time, air bubbles may exist at the bonding area in the gap between the outer mold 2 and the surface of the wine box. The expansion of the elastic membrane 3 can fill the gap, thereby effectively eliminating air bubbles. After pressing, the inflation gap 4 is evacuated, causing the elastic membrane 3 to gradually shrink and separate from the surface of the wine box, facilitating subsequent operations.

[0041] The above are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
