Description

Technical Field

[0001] This application relates to the field of packaging paper processing technology, and in particular to a surface treatment device for wine box packaging paper. Background Technology

[0002] In the packaging of alcoholic beverages, the quality and appearance of the packaging box have a crucial impact on the product's market competitiveness.

[0003] Currently, in the production process of wine boxes, after the paper is folded into a wine box, the surface and interior flatness of the wine box are not ideal.

[0004] Specifically, during the paper folding process, the shape of the finished wine box is not regular enough. In actual production, due to the accumulation of various errors during the folding process, the surface of the wine box will be uneven, and there may also be uneven gaps inside. Each side may be bent and deformed to a certain extent, resulting in angular deviations. As a result, the finished wine box is often not a standard rectangle. This makes it difficult to accurately align the wine box lid when it is glued to the wine box. The gap between the wine box lid and the main body of the wine box is not the same size. This not only affects the overall sealing of the packaging, but also allows the wine product to be affected by external environmental factors such as air and moisture, reducing the appearance quality of the product.

[0005] To address the aforementioned issues, a surface treatment device for wine box packaging paper has been designed. Utility Model Content

[0006] This application provides a surface treatment device for wine box packaging paper to solve the problem in related technologies that the formed wine boxes are often not standard rectangles, resulting in inaccurate alignment when the wine box lid is glued to the wine box.

[0007] In a first aspect, a surface treatment device for wine box packaging paper is provided, comprising: A conveyor, used to transport shaped wine boxes; The conveyor is equipped with a U-shaped enclosure to block the conveyed wine boxes. The conveyor is equipped with a pressing station, and a feeding mechanism is provided above the pressing station. The feeding mechanism is used to put the wine boxes inside the enclosure into the pressing station in sequence. A hot pressing mechanism is provided on one side of the pressing station. The hot pressing mechanism includes a pushing unit and a positioning post arranged opposite each other on both sides of the pressing station, and a pressing unit arranged outside the positioning post. The pushing unit is used to push the wine box formed on the pressing station to the positioning post. The positioning post is inserted and cooperates with the wine box to fill and heat the inside of the wine box. The pressing unit presses the side of the wine box.

[0008] In some embodiments, the feeding mechanism includes: a housing disposed outside the conveyor, a linear sliding rail disposed inside the housing, and a fixed seat disposed on the slider of the linear sliding rail, the linear sliding rail being used to drive the fixed seat to move along the length of the pressing station; Two electric push rods are arranged opposite each other on the fixed base. The bottom end of the piston rod of the electric push rod is provided with a fixing plate, and the two ends of the fixing plate are provided with vacuum suction cups. The vacuum suction cups are used to adsorb the wine box.

[0009] In some embodiments, the pushing unit includes a cylinder disposed within a housing, and a pushing block is disposed on the piston rod of the cylinder.

[0010] In some embodiments, the positioning post includes a rectangular frame plate disposed within the housing, and a rectangular post is disposed within the rectangular frame plate, the rectangular post being disposed opposite to the pushing block; The rectangular column is adapted to the inner cavity of the wine box, and multiple heating wires are installed inside the rectangular column.

[0011] In some embodiments, the clamping unit includes four clamping plates arranged in a rectangular shape within a rectangular frame plate. The four clamping plates are correspondingly arranged on the four sides of the rectangular column, and there is a gap between the clamping plates and the rectangular column for accommodating the wine box. The clamping unit also includes four electric push rods 2 arranged in a rectangular shape on the outside of the rectangular frame plate. The piston rods of the electric push rods 2 are connected to the corresponding clamping plates and are used to push the clamping plates away from or closer to the rectangular column.

[0012] In some embodiments, the conveyor is a belt conveyor, and the pressing unit is arranged in the middle of the conveyor belt.

[0013] In some embodiments, the enclosure includes a U-shaped bar arranged above the conveyor belt, with two sets of fixing bars on both sides of the U-shaped bar and a mounting base at the other end of the fixing bar, the mounting base being mounted on the conveyor.

[0014] This application provides a surface treatment device for wine box packaging paper. By filling and heating the inside of the wine box with positioning columns and pressing the sides of the wine box with pressing units, the unevenness of the surface and inside of the wine box after molding can be effectively improved. Heating can make the fibers of the wine box paper softer and easier to shape, while filling and pressing can eliminate wrinkles and deformation of the paper, making the surface and inside of the wine box smoother and flatter, thereby improving the overall quality of the wine box.

[0015] The conveyor, pressing station, feeding mechanism, and hot pressing mechanism ensure that the wine box presents a more regular rectangular shape after processing, enabling the wine box lid to be aligned with the wine box body, ensuring the strength and sealing of the bond, and reducing bonding errors and product quality problems caused by irregular shape.

[0016] The coordinated use of conveyors and feeding mechanisms enables rapid feeding of wine boxes, improving the continuity of the production process. Simultaneously, the hot-pressing mechanism can quickly and efficiently heat-press the wine boxes, shortening the processing time for individual boxes, thereby improving overall production efficiency and reducing production costs.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a surface treatment device for wine box packaging paper, which can solve the problem in related technologies that the formed wine boxes are often not standard rectangles, resulting in inaccurate alignment when the wine box lid is glued to the wine box.

[0022] Please see Figures 1-3 A surface treatment device for wine box packaging paper includes: a conveyor 1 for conveying formed wine boxes; a U-shaped enclosure 2 on the conveyor 1 to block the conveyed wine boxes; a pressing station 3 on the conveyor 1, a feeding mechanism 5 above the pressing station 3 for sequentially placing the wine boxes within the enclosure 2 into the pressing station 3; a hot pressing mechanism 4 on one side of the pressing station 3, the hot pressing mechanism 4 including a pushing unit 41 and a positioning post 42 oppositely arranged on both sides of the pressing station 3, and a pressing unit 43 arranged outside the positioning post 42, the pushing unit 41 for pushing the formed wine boxes on the pressing station 3 to the positioning post 42, the positioning post 42 interlocking with the wine box to fill and heat the inside of the wine box, and the pressing unit 43 pressing the sides of the wine box.

[0023] Conveyor 1 operates continuously, transporting the formed wine boxes forward. The function of barrier 2 is to block the wine boxes during the transport process, preventing them from deviating from the predetermined position or falling, and ensuring that the wine boxes can be orderly gathered within the area defined by barrier 2.

[0024] The feeding mechanism 5 is located above the pressing station 3, and puts the wine boxes inside the enclosure 2 into the pressing station 3 in sequence.

[0025] Subsequently, the pushing unit 41 is activated, pushing the wine box formed on the pressing station 3 toward the positioning post 42. The positioning post 42 is adapted to the shape of the wine box. When the wine box is pushed to the positioning post 42, the positioning post 42 is inserted into the inside of the wine box. While inserting into the wine box, the inside of the wine box is heated. At the same time, the positioning post 42 fills the internal space of the wine box, which helps to make the inside of the wine box more flat and regular.

[0026] While the positioning post 42 fills and heats the inside of the wine box, the pressing unit 43 starts to work, pressing the sides of the wine box. The pressing unit 43 applies appropriate pressure to multiple sides of the wine box at the same time, making the sides of the wine box flatter and further ensuring the overall shape of the wine box is regular.

[0027] By filling and heating the inside of the wine box with positioning post 42, and pressing the sides of the wine box with pressing unit 43, the unevenness of the surface and inside of the wine box after molding can be effectively improved. Heating can make the fibers of the wine box paper softer and easier to shape, while filling and pressing can eliminate the wrinkles and deformation of the paper, making the surface and inside of the wine box smoother and flatter, thereby improving the overall quality of the wine box.

[0028] The conveyor 1, pressing station 3, feeding mechanism 5 and hot pressing mechanism 4 ensure that the wine box presents a more regular rectangular shape after processing, which enables the wine box lid to be aligned with the wine box body, ensuring the firmness and sealing of the bond, and reducing bonding errors and product quality problems caused by irregular shape.

[0029] The coordinated operation of conveyor 1 and feeding mechanism 5 enables rapid feeding of wine boxes, improving the continuity of the production process. Simultaneously, the hot-pressing mechanism 4 can quickly and efficiently heat-press the wine boxes, shortening the processing time for a single box, thereby improving overall production efficiency and reducing production costs.

[0030] like Figure 2 and Figure 3 As shown, in one embodiment, the feeding mechanism 5 includes: a housing 51 disposed outside the conveyor 1; a linear sliding rail 52 disposed inside the housing 51; and a fixed seat 53 disposed on the slider of the linear sliding rail 52. The linear sliding rail 52 is used to drive the fixed seat 53 to move along the length of the pressing station 3. Two electric push rods 54 are disposed opposite each other on the fixed seat 53. The piston rod of each electric push rod 54 is provided with a fixing plate 55 at its bottom end. Vacuum suction cups 56 are provided at both ends of the fixing plate 55. The vacuum suction cups 56 are used to adsorb wine boxes. The vacuum suction cups 56 are connected to an external vacuum generator through pipes.

[0031] When it is necessary to pick up the wine box, the electric push rod 54 is activated, and its piston rod extends downward, driving the fixing plate 55 fixed at the bottom of the piston rod to move downward. Vacuum suction cups 56 are provided at both ends of the fixing plate 55. As the fixing plate 55 moves downward, the vacuum suction cups 56 gradually approach the wine box inside the enclosure 2. When the vacuum suction cups 56 come into contact with the surface of the wine box, a negative pressure is formed inside the vacuum suction cups 56 by a vacuum generating device (not shown in the figure), thereby tightly adhering the wine box to the vacuum suction cups 56.

[0032] After successfully adsorbing the wine box, the piston rod of the electric push rod 54 retracts, lifting the wine box upwards and detaching it from the enclosure 2. Subsequently, the linear sliding rail 52 drives the fixed base 53 to move along the length of the pressing station 3, moving the vacuum suction cup 56 with the wine box adsorbed to directly above the pressing station 3. Then, the electric push rod 54 starts again, and the piston rod extends downwards, accurately placing the wine box on the pressing station 3, completing one feeding process. Afterwards, the vacuum suction cup 56 releases the negative pressure, releasing the wine box, and the feeding mechanism returns to its initial position, ready for the next feeding operation.

[0033] The linear sliding rail 52 can precisely control the movement position and distance of the fixed seat 53. Combined with the vertical control of the electric push rod 54, the vacuum suction cup 56 can accurately pick up the wine box from the enclosure 2 and place it on the pressing station 3, which greatly improves the accuracy and stability of feeding.

[0034] The vacuum suction cup 56 has good flexibility and adaptability, and can adapt to the surface of wine boxes of different shapes and sizes, ensuring that the wine boxes will not fall off during the feeding process, thus improving the versatility and applicability of the equipment.

[0035] like Figure 2 and Figure 4 As shown, in one embodiment, the pushing unit 41 includes a cylinder 411 disposed within the housing 51, and a pushing block 412 is disposed on the piston rod of the cylinder 411.

[0036] After the wine box is placed on the pressing station 3 by the feeding mechanism 5, the pushing unit 41 is in standby mode. At this time, the piston rod of the cylinder 411 is in retracted mode, and the pushing block 412 is located in the initial position away from the wine box, so as not to interfere with the placement of the wine box and other subsequent operations.

[0037] When the equipment control system issues a push command, cylinder 411 starts to work. The compressed air in cylinder 411 pushes the piston rod to extend outward. The piston rod drives the push block 412 fixed on it to move forward together. Driven by cylinder 411, the push block 412 moves in a straight line towards the positioning post 42. When the push block 412 contacts the wine box on the pressing station 3, it continues to apply a pushing force to push the wine box from the pressing station 3 to the positioning post 42, so that the positioning post 42 can be smoothly inserted into the wine box.

[0038] After the wine box is successfully pushed to the positioning post 42, the piston rod of the cylinder 411 remains extended, and the pushing block 412 is in close contact with the wine box.

[0039] It should be noted that, in order to automatically detach the wine box from the positioning post 42 after hot pressing, a bonding plate is provided at the end of the push block 412. The bonding plate is the same size as the bottom of the wine box. Through holes are opened on both sides of the bonding plate, and vacuum suction cups are installed inside the through holes. The vacuum suction cups are fixed on the fixing block 512 and connected to an external vacuum generator through pipes. When the push block 412 contacts the wine box on the pressing station 3, a negative pressure is formed inside the vacuum suction cup to adsorb the wine box. After the wine box is pressed into shape, the piston rod retracts, driving the push block 412, the bonding plate and the wine box back to their original positions. Then, the vacuum suction cup 56 releases the negative pressure and releases the wine box. The wine box continues to be transported by the conveyor 1 to the next process.

[0040] like Figure 2 and Figure 4As shown, in one embodiment, the positioning post 42 includes a rectangular frame plate 421 disposed within the housing 51, and a rectangular post 422 disposed within the rectangular frame plate 421. The rectangular post 422 is disposed opposite to the push block 412. The rectangular post 422 is adapted to the inner cavity of the wine box, and multiple heating wires are disposed inside the rectangular post 422. The end of the rectangular frame plate 421 near the conveyor 1 is open for the wine box to enter, and the end of the rectangular frame plate 421 away from the conveyor 1 is sealed to position the head of the wine box. The length of the rectangular post 422 matches the length of the wine box.

[0041] The cylinder 411 of the pushing unit 41 drives the pushing block 412 to push the wine box on the pressing station 3 toward the positioning post 42. Since the rectangular post 422 is adapted to the inner cavity of the wine box, under the continuous action of the pushing force, the rectangular post 422 can be smoothly inserted into the inside of the wine box. At this time, the closed side of the rectangular frame plate 421 contacts the opening of the wine box, and the entire inner cavity of the wine box contacts the rectangular post 422, ensuring that the rectangular post 422 will not shift during the insertion process and ensuring the accuracy of the insertion.

[0042] At the same time, multiple heating wires inside the rectangular column 422 begin to operate. These wires generate heat when energized, which is then transferred to the interior of the wine box through the rectangular column 422. Under the influence of this heat, the fibers of the wine box paper become softer, which facilitates the subsequent pressing process and allows the wine box to be better shaped.

[0043] The rectangular frame plate 421 provides a stable support structure for the rectangular column 422. The rectangular column 422 is adapted to the inner cavity of the wine box and can tightly fill the internal space of the wine box, effectively eliminating gaps and wrinkles inside the wine box, making the inside of the wine box more flat, providing a good foundation for the subsequent pressing process, and helping to improve the overall quality of the wine box.

[0044] Multiple heating wires inside the rectangular column 422 can quickly and evenly generate heat and transfer it to the inside of the wine box, causing the fibers of the wine box paper to soften rapidly. Under the action of the pressing unit 43, the wine box can be shaped more quickly, shortening the heat pressing time and improving production efficiency.

[0045] like Figure 2 and Figure 4 As shown, in one embodiment, the pressing unit 43 includes four pressing plates 431 arranged in a rectangular shape within a rectangular frame plate 421. The four pressing plates 431 are correspondingly arranged on the four sides of the rectangular column 422, and there is a gap between the pressing plates 431 and the rectangular column 422 for accommodating the wine box. The clamping unit 43 also includes four electric push rods 432 arranged in a rectangular shape on the outside of the rectangular frame plate 421. The piston rods of the electric push rods 432 are connected to the corresponding clamping plates 431 and are used to push the clamping plates 431 away from or closer to the rectangular column 422.

[0046] Before the wine box is pushed into the positioning post 42 area, the four electric push rods 432 are in the initial state, and the four clamping plates 431 maintain a certain initial gap with the rectangular post 422 to allow the wine box to enter smoothly.

[0047] When the pushing unit 41 pushes the wine box to the positioning post 42, the rectangular post 422 is inserted into the inner cavity of the wine box. The wine box is located in the gap between the four pressing plates 431 and the rectangular post 422. The four electric push rods 432 are activated simultaneously, and their piston rods extend, pushing the corresponding pressing plates 431 to move towards the rectangular post 422. Since the four pressing plates 431 are arranged in a rectangle on the four sides of the rectangular post 422, they will apply pressure to the wine box from four directions simultaneously.

[0048] While the pressure plate 431 applies pressure to the wine box, the heating wire inside the rectangular column 422 heats up, and the heat is transferred to the inside of the wine box. Under the combined action of pressure and heat, the fibers of the wine box paper gradually soften and rearrange, and the wine box is pressed and shaped to achieve the ideal flatness and shape.

[0049] Once the hot-pressing process reaches the set time or meets specific conditions, the piston rod of the electric push rod 432 begins to retract, driving the pressure plate 431 away from the rectangular column 422 and back to its initial position. At this point, the wine box has completed the hot-pressing process and can be removed for subsequent processes.

[0050] like Figure 1 As shown, in one embodiment, the conveyor 1 is a belt conveyor, and the pressing unit 43 is arranged in the middle of the conveyor belt of the conveyor 1.

[0051] After the belt conveyor 1 is started, its conveyor belt continues to run at the set speed and direction. The wine box is placed at the beginning of the conveyor belt, and as the conveyor belt moves, the wine box is smoothly transported towards the middle of the conveyor belt.

[0052] After the wine box undergoes heat pressing, it is transported to the end of the conveyor belt as the conveyor belt continues to operate, and then proceeds to the next process.

[0053] like Figure 1 As shown, in one embodiment, the enclosure 2 includes a U-shaped bar arranged above the conveyor belt, two sets of fixing bars are provided on both sides of the U-shaped bar, and a mounting seat is provided at the other end of the fixing bar, and the mounting seat is provided on the conveyor 1.

[0054] As the main structural component of the enclosure 2, the U-shaped bar faces the initial end of the conveyor 1 where the conveyor starts to transport the goods. It can effectively wrap around the conveyor belt to form a relatively closed space, which can limit and protect the wine boxes on the conveyor belt.

[0055] The U-shaped rod is stably fixed to the conveyor 1 by the fixing rod, ensuring that the enclosure 2 will not shake or shift during operation.

[0056] The mounting base is directly mounted on the conveyor 1. This design makes the connection between the enclosure 2 and the conveyor 1 more secure, and makes installation and disassembly more convenient, facilitating equipment maintenance and repair.

[0057] When the belt conveyor 1 starts and the wine box is placed on the conveyor belt to begin conveying, the U-shaped bar of the enclosure 2 is located above the conveyor belt and plays a lateral limiting role for the wine box. Due to the obstruction of the U-shaped bar, the wine box will not easily slip off the sides of the conveyor belt during the conveying process, ensuring that the wine box can move steadily along the direction of the conveyor belt.
