Description

Technical Field

[0001] This utility model belongs to the technical field of packaging material processing equipment, specifically relating to a reverse groove pressing device for wine box shell. Background Technology

[0002] As packaging for high-end liquors, the appearance quality and durability of the wine box casing are of paramount importance. Currently, wine box casings on the market often use grey board as the inner lining, covered with high-quality outer paper such as imitation leather or specialty paper, and bonded together with adhesive. However, during long-term use, especially after repeated opening and closing and experiencing vibrations during transportation, the outer paper and the box blank (grey board) are prone to delamination, bubbling, or misalignment in stress-concentrated areas such as grooves (crease lines). This problem is particularly prominent with elastic or dense materials such as imitation leather and specialty paper, seriously affecting the product's appearance quality and lifespan, and damaging the brand image.

[0003] In the existing technology, there is a lack of specialized equipment for reinforcing the slotting lines before the casing is formed. Therefore, there is an urgent need for a device that can pre-strengthen the bond strength between the paper and the box blank at the slotting line location to fundamentally solve the problem of delamination and misalignment. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a reverse grooving device for wine box shells. By reverse rolling the groove line before molding, the bonding strength between the face paper and the box blank is significantly enhanced, and delamination and misalignment are prevented.

[0005] The purpose of this utility model can be achieved through the following technical solution: a reverse grooving device for wine box shells, characterized in that the grooving device includes a frame, a worktable fixed on the top of the frame, a set of slide rails fixed on the upper surface of the worktable, and a slide table slidably connected on the slide rails; a lead screw is rotatably connected to the top of the worktable, and the slide table and the lead screw are threadedly connected; a servo motor capable of driving the lead screw to rotate is also provided on the worktable; mounting brackets are fixed on both sides of the top of the frame, and a grooving shaft is provided between the two mounting brackets, and the two ends of the grooving shaft are rotatably connected to the two mounting brackets respectively; a plurality of grooving wheels are provided on the grooving shaft, each grooving wheel including a mounting sleeve made of stainless steel and a grooving wheel body made of nylon material fixed together, each mounting sleeve being sleeved on the grooving shaft, and each mounting sleeve being provided with a locking screw.

[0006] Preferably, each of the mounting brackets is vertically fixed with a set of sliding rods, and each sliding rod is slidably connected with a slider. The two ends of the pressure groove shaft are rotatably connected to the two sliders through bearings. Each slider is vertically fixed with a screw, each screw passes through the top of the corresponding mounting bracket, and each screw is threadedly connected to an adjusting turntable above the top of the corresponding mounting bracket. Each screw is fitted with a compression spring, and the two ends of each compression spring abut against the inner top of the corresponding mounting bracket and the top of the corresponding slider.

[0007] Preferably, the upper surface of the slide is coated with an anti-scratching plate, which is made of polytetrafluoroethylene (PTFE). The top of the anti-scratching plate is provided with a first limiting strip and a second limiting strip, and the first limiting strip is fixedly connected to the anti-scratching plate. Both ends of the second limiting strip are bent downward to form two fixing parts, one of which is provided with a locking bolt. When the second limiting strip is fixed to the anti-scratching plate, one of its fixing parts abuts against an outer peripheral surface of the slide, and the locking bolt on the other fixing part abuts against an opposite outer peripheral surface of the slide.

[0008] Working principle: During operation, the semi-finished wine box shell that has been covered and glued but has not yet been folded and shaped is precisely positioned on the anti-scratch plate of the slide table, so that its opposite two sides abut against the first limit strip and the second limit strip respectively, thereby ensuring that the groove position is aligned with the preset groove line.

[0009] After the equipment is started, the servo motor drives the lead screw to rotate according to the preset program, which in turn drives the slide table carrying the workpiece to make a smooth reciprocating linear motion along the slide rail. When the shell moves to the bottom of the grooving wheel, the grooving wheel reciprocates and rolls the preset grooving line on the shell under the constant and flexible pressure provided by the compression spring.

[0010] The core of this process lies in "reverse" grooving: that is, strengthening the groove structure before the final folding and creasing. Nylon grooving rollers evenly transfer pressure to the face paper, effectively eliminating residual air in the adhesive layer through rolling action. This promotes deeper penetration and interweaving of adhesive molecules, enabling a dense, microscopic bond between the face paper and the box blank (grey board) in the groove area where stress is most concentrated. This significantly enhances the adhesive strength and structural integrity at that point. Simultaneously, the properties of nylon ensure that this process will not cause any scratches or wear to the delicate leather surface.

[0011] After completing one set rolling cycle, the slide automatically returns to the starting position, and the operator removes the pre-strengthened workpiece, which can then be transferred to the subsequent final indentation and folding forming process.

[0012] The advantages of this utility model are:

[0013] 1. Effectively prevents delamination and misalignment: The core of this invention lies in performing "reverse" pre-pressing on the pre-set grooved lines before the outer casing is officially pressed and folded. This process, through the pressure of the pressing rollers, squeezes the face paper and the box blank more tightly at the grooved lines, eliminating any air bubbles that may exist in this area, promoting the penetration and fusion of the adhesive, and greatly enhancing the bonding strength of this weak area. This effectively resists the stress caused by repeated opening and closing and vibration during subsequent use, preventing delamination and misalignment.

[0014] 2. Protective lining paper with good adaptability: The grooving rollers are made of nylon, which is hard yet slightly flexible. This allows for sufficient pressure without scratching or abrading the surface of delicate materials such as imitation leather and specialty paper. Furthermore, the position of the grooving rollers on the grooving shaft is adjustable, precisely aligning with the grooving lines of different sized wine box casings, making it highly versatile.

[0015] 3. Precise positioning and scratch prevention: The anti-scratch plate made of polytetrafluoroethylene (Teflon) on the slide, along with the adjustable first and second limit strips, together form a precisely positioned and extremely smooth bearing platform. It can reliably limit the casing to the correct stroke, and its low coefficient of friction surface ensures that the bottom surface of the casing will not be scratched by friction during the pressing process, thus protecting the product's appearance in all aspects.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1 , Figure 2 and Figure 3As shown, a reverse grooving device for a wine box includes a frame 1, a worktable 2 fixed to the top of the frame 1, a set of slide rails 3 fixed to the upper surface of the worktable 2, and a slide table 31 slidably connected to the slide rails 3; a lead screw 32 rotatably connected to the top of the worktable 2, and the slide table 31 and the lead screw 32 are threadedly connected; a servo motor 33 that can drive the lead screw 32 to rotate is also provided on the worktable 2; mounting brackets 4 are fixed to both sides of the top of the frame 1, and a grooving shaft 41 is provided between the two mounting brackets 4, and the two ends of the grooving shaft 41 are rotatably connected to the two mounting brackets 4 respectively; a plurality of grooving wheels are provided on the grooving shaft 41, and each grooving wheel includes a mounting sleeve 42 made of stainless steel and a grooving wheel body 43 made of nylon material fixed together; each mounting sleeve 42 is sleeved on the grooving shaft 41, and each mounting sleeve 42 is provided with a locking screw 44.

[0022] In this grooving device, the slide table 31 is driven by only one set of lead screw 32 drive system, while the rolling components rotate passively. Compared with traditional rolling equipment, it eliminates complex components such as motors and reducers that drive the rollers, making its structure compact and its cost relatively low. At the same time, since the rollers rotate completely passively and have almost no slippage with the surface of the casing, it can effectively protect the face paper, making it less prone to scratches.

[0023] The grooving roller 43 is made of nylon, which is hard yet slightly tough, allowing it to apply sufficient pressure without scratching or abrading the surface of delicate materials such as imitation leather and specialty paper. Meanwhile, the position of the grooving roller on the grooving shaft 41 is adjustable, enabling precise alignment with the grooving lines of different sized wine box shells, thus offering high versatility.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, each mounting bracket 4 has a set of sliding rods 45 vertically fixed on it, and each sliding rod 45 has a slider 46 slidably connected to it. The two ends of the grooving shaft 41 are rotatably connected to the two sliders 46 through bearings. Each slider 46 has a screw 47 vertically fixed to its top, and each screw 47 passes through the top of the corresponding mounting bracket 4. Each screw 47 is threaded to an adjusting turntable 48 above the top of the corresponding mounting bracket 4. Each screw 47 is fitted with a compression spring 49, and the two ends of each compression spring 49 abut against the inner top of the corresponding mounting bracket 4 and the top of the corresponding slider 46, respectively. By rotating the adjusting turntable 48, the slider 46 can be raised or lowered by the screw 47, thereby precisely adjusting the initial reserved gap between the lower edge of the grooving wheel body 43 of the grooving wheel and the upper surface of the slide table 31 to accommodate workpieces with different thicknesses of shells. When the slide 31 carries the workpiece into the gap, the pressure wheel is lifted up, and the compression spring 49 is further compressed and generates elastic force, which is the rolling pressure applied to the shell.

[0025] like Figure 1 , Figure 2and Figure 3 As shown, the upper surface of the slide table 31 is coated with a scratch-resistant plate 5, which is made of polytetrafluoroethylene (PTFE). The top of the scratch-resistant plate 5 is provided with a first limiting strip 51 and a second limiting strip 52, and the first limiting strip 51 is fixedly connected to the scratch-resistant plate 5. Both ends of the second limiting strip 52 are bent downwards to form two fixing parts 53, one of which is provided with a locking bolt 54. When the second limiting strip 52 is fixed to the scratch-resistant plate 5, one fixing part 53 abuts against an outer peripheral surface of the slide table 31, and the locking bolt 54 on the other fixing part 53 abuts against an opposite outer peripheral surface of the slide table 31. By abutting one fixing part 53 against one side of the slide table 31 and tightening the locking bolt 54 so that its top abuts against the other side of the slide table 31, the second limiting strip 52 can be quickly locked onto the scratch-resistant plate 5, thus forming a pre-positioning area together with the first limiting strip 51. This allows the operator to quickly position and load materials when processing the same type of leather, improving processing efficiency.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
