Description

Technical Field

[0001] The utility model relates to the technical field of film material equipment, in particular to a film cutting equipment. Background Art

[0002] In modern industrial production, especially in the food, beverage, cosmetics and other industries, glass bottles are commonly used as packaging containers. The safety and efficiency of their transportation and storage have always been the focus of attention in the logistics and packaging fields. The traditional method of packaging glass bottles is often to use individual packaging, and then put them into cartons or wooden boxes for transportation. This method not only consumes a lot of packaging materials, but also lacks effective support and fixation, which easily causes the glass bottles to collide and break during transportation, causing economic losses.

[0003] In order to solve the above problems, the concept of bottle pallet (multi-layer glass bottles stacked on pallets and wrapped with film) has been widely promoted and applied in recent years. Bottle pallet is made by stacking glass bottles in multiple layers and wrapping them tightly with film, which not only greatly saves packaging materials and improves space utilization, but also reduces shaking and collision during transportation due to the mutual support between glass bottles, significantly reduces the breakage rate, and improves transportation efficiency and safety. However, after the bottle pallet arrives at the destination, the outer film needs to be removed before the next step of processing. The traditional manual film removal method is inefficient, time-consuming and labor-intensive, and easily causes the outer film to remain or the glass bottles to be damaged. With the expansion of production scale, the limitations of this manual operation have become increasingly prominent, especially in large-scale production lines, where the efficient and non-destructive removal of the outer film has become a key issue that needs to be solved urgently.

[0004] Although there are automatic film removal machines on the market, they are generally expensive, have strict requirements on sites and materials, and often require additional bottle unloading machines, which limits their popularization and application in small and medium-sized enterprises. Therefore, developing an automatic equipment with reasonable cost, simple operation, and the ability to efficiently and safely remove the outer film of bottle stacks has become an urgent issue that needs to be solved in the current packaging and logistics industry.

[0034] Refer to Figures 1 to 7 , a film cutting device, comprising:

[0035] Frame;

[0036] The first cutting device 100 includes a first cutter head 130, a first elastic telescopic member, a positioning guide rod 140, and an adjusting bracket 190. The first elastic telescopic member is installed on the frame, the adjusting bracket 190 is installed at one end of the first elastic telescopic member away from the frame, the positioning guide rod 140 and the first cutter head 130 are installed on the adjusting bracket 190. The positioning guide rod 140 is arc-shaped, and the curve profile of the positioning guide rod 140 is adapted to the bottle stack 110. The first cutter head 130 is arranged behind the positioning guide rod 140;

[0037] The second cutting device 120 includes a second cutter head 165 and a second elastic telescopic member. The second cutting device 120 is disposed below the first cutting device 100. The second elastic telescopic member is mounted on the frame, and the second cutter head 165 is disposed at one end of the second elastic telescopic member away from the frame.

[0038] Wherein, when the bottle stack 110 abuts against the positioning guide rod 140, the bottle stack 110 pushes the first elastic telescopic member to retract, so as to adjust the distance between the first cutter head 130 and the bottle stack 110.

[0039] By providing the first cutting device 100 and the second cutting device 120, the equipment can automatically identify and adapt to the size change of the bottle stack 110 without manual intervention, greatly improving the cutting efficiency of the outer packaging film, reducing the labor cost and operation time. The positioning guide rod 140 of the first cutting device 100 is designed to be arc-shaped and matches the contour of the bottle stack 110, which can guide the first cutter head 130 to accurately cut the outer packaging film. At the same time, it avoids the direct contact between the cutter head and the bottle body, reduces the possibility of bottle body damage, and ensures the integrity and aesthetics of the product. The setting of the first elastic telescopic member enables the first cutter head 130 to automatically adjust the distance from the bottle stack 110 according to the size of the bottle stack 110, and can maintain the stability and consistency of cutting even when facing bottle stacks 110 of different sizes, enhancing the flexibility and adaptability range of the equipment. The arc-shaped design of the positioning guide rod 140 in contact with the bottle stack 110 not only achieves accurate positioning, but also plays a certain buffering role, reducing the risk of instability or bottle body dropping caused by sudden impact during the cutting process of the bottle stack 110, and improving the safety of the entire operation process. Through its unique design and automation function, this film cutting equipment significantly improves the cutting efficiency and accuracy of the outer packaging film, while reducing the production cost and enhancing the operation safety.

[0040] The first elastic telescopic member includes a first elastic member 160 and a first sliding seat 150. The adjusting bracket 190 is fixedly connected to the first sliding seat 150. One end of the first elastic member 160 is connected to the first sliding seat 150, and the other end is connected to the frame. The fixed connection between the first sliding seat 150 and the adjusting bracket 190, combined with the expansion and contraction of the first elastic member 160, provides stable support and flexible adjustment for the cutting device, ensuring the stability and safety during the cutting process.

[0041] The first elastic member 160 is one of a spring, a rubber washer or a corrugated pipe. Using the first elastic member 160 can ensure that the first cutting device 100 has good elastic response characteristics. The first elastic member 160 can quickly respond and adjust the distance between the first cutter head 130 and the bottle stack 110 by retracting or compressing to ensure the cutting accuracy.

[0042] Refer toFigure 6 The first cutter head 130 includes a piercing part 200 and a cutting part 210. The blade thickness of the cutting part 210 is greater than that of the piercing part 200, and an arc transition treatment is provided between the cutting part 210 and the piercing part 200. The design of the piercing part 200 can easily penetrate the outer packaging film of the bottle stack 110, while the thicker blade edge of the cutting part 210 ensures the stability and efficiency of the cutting process, avoids jamming or tearing during the cutting process, and improves the overall cutting speed.

[0043] The adjusting bracket 190 includes a vertical adjusting part and a horizontal adjusting part. The vertical adjusting part is provided with a first clamp. The adjusting bracket 190 is fixed to the first elastic telescopic member through the first clamp. The horizontal adjusting part is provided with a second clamp. The first cutter head 130 is installed through the second clamp. The use of the first clamp and the second clamp simplifies the installation and disassembly process of the adjusting bracket 190, the first elastic telescopic member and the first cutter head 130, facilitates maintenance and adjustment, and saves the time for equipment maintenance and debugging.

[0044] The positioning guide rod 140 is provided with a convex part, and the convex part is arranged in a direction away from the first elastic telescopic member. The convex part on the positioning guide rod 140 is designed to better contact the surface of the bottle stack 110, increase the contact area, ensure that when the bottle stack 110 passes through, the positioning guide rod 140 can stably guide the bottle stack 110, avoid the swing or deviation of the bottle stack 110 during the moving process, and thus improve the accuracy and stability of cutting.

[0045] The film cutting device includes two groups of first cutting devices 100 and two groups of second cutting devices 120. The two groups of first cutting devices 100 are symmetrically arranged along the advancing direction of the bottle stack 110, and the two groups of second cutting devices 120 are symmetrically arranged along the advancing direction of the bottle stack 110. The symmetrically arranged cutting devices can ensure that the outer packaging film of the bottle stack 110 is evenly cut on all sides, avoid the problems of film residue or incomplete cutting that may be caused by unilateral cutting, improve the cutting quality; can apply force evenly, avoid the inclination or shaking of the bottle stack 110 during the cutting process due to uneven force, enhance the stability of the cutting process, and reduce the risk of bottle body damage. Refer to Figure 2 and Figure 6 The second elastic telescopic member includes a second sliding seat 180 and a second elastic member 170. The second cutter head 165 is fixedly connected to the second sliding seat 180. One end of the second elastic member 170 is connected to the second sliding seat 180, and the other end is connected to the machine frame. The second sliding seat 180 and the second elastic member 170 reduce the direct impact on the bottle body and reduce the risk of bottle body damage. It can be understood that the first sliding seat 150 and the second sliding seat 180 can be implemented by using linear guide rails, linear bearings or sliding sleeves, etc.

[0046] The edge of the positioning guide rod 140 is provided with an arc transition treatment, which can avoid scratching or damaging the surface of the bottle body by the edge of the positioning guide rod 140 and ensure the intact appearance of the bottle body.

[0047] Refer to Figure 2 and Figure 3 , the first cutter head 130 is set corresponding to the bottleneck, and the second cutter head 165 is set corresponding to the bottle body. By respectively setting the cutting devices for the bottleneck and the bottle body, it is possible to avoid the additional pressure or damage that may be caused to the bottle body during one-time cutting. Especially since the size of the bottleneck is relatively variable, this design can effectively reduce the risk of damage to the bottle body during the cutting process.

[0048] It can be understood that the second cutting device 120 does not need to be provided with a positioning guide rod 140. Since the designs and styles at the bottleneck of the glass bottle are relatively variable, while the designs at the bottle body are relatively the same, the second cutting device 120 does not need to be provided with a positioning guide rod 140 and can directly install the second cutter head 165 at the second elastic telescopic component, thereby reducing the complexity of the structure. By implementing differential cutting strategies for the bottleneck and the bottle body respectively, this device significantly reduces the risk of damage to the bottle body during the cutting process. Especially when dealing with the bottle stack 110 with variable bottleneck sizes, this design is particularly crucial. The precise matching of the first cutter head 130 with the bottleneck ensures the accuracy and safety of cutting. The direct installation of the second cutter head 165 on the second elastic telescopic component not only simplifies the structure of the second cutting device 120 but also improves the overall reliability and durability. The second cutting device 120 omits the positioning guide rod 140, which not only reduces the complexity of the device but also reduces potential failure points, further improving the stability and maintenance convenience of the equipment.

[0049] Refer to Figures 1 to 7 , in this embodiment, an automatic film cutting device for removing the outer film of the glass bottle stack 110 is provided. The first cutting device 100 is installed on the upper part of the rack, facing the upper end of the bottle stack 110. The first cutting device 100 includes a first cutter head 130, the cutter head is made of cemented carbide, with good wear resistance and cutting efficiency; the first elastic telescopic component uses a highly elastic stainless steel spring, which can automatically adjust the position of the cutter head according to the thickness of the bottle stack 110 to ensure the accuracy of cutting; the positioning guide rod 140: adopts an arc design and is made of wear-resistant plastic, which can be in close contact with the bottle body and guide the bottle stack 110 to pass through the cutting area smoothly; the adjusting bracket 190: is used to fix the positioning guide rod 140 and the first cutter head 130, and can be finely adjusted by bolts to adapt to bottle stacks 110 of different sizes.

[0050] When the bottle stack 110 is conveyed to the cutting area, the bottle stack 110 first contacts the positioning guide rod 140 of the first cutting device 100. The arc design of the positioning guide rod 140 enables it to fit the bottle body. At the same time, the compression of the first elastic telescopic component adjusts the distance between the first cutter head 130 and the bottle stack 110, ensuring that the cutter head only touches the outer packaging film without damaging the bottle body. As the bottle stack 110 moves, the first cutter head 130 precisely cuts the outer packaging film under the guidance of the positioning guide rod 140. Subsequently, the bottle stack 110 continues to move to the second cutting device 120 to complete the cutting of the bottom outer packaging film. Place the bottle stack 110 on the conveyor line to ensure its stability and correct alignment. When cutting the film, first start the conveyor line, and the bottle stack 110 begins to move towards the cutting area. The upper and lower ends of the bottle stack 110 respectively contact the first cutting device 100 and the second cutting device 120, triggering the compression of the first elastic telescopic component and the second elastic telescopic component. The first cutter head 130 and the second cutter head 165 cut into the outer packaging film. The bottle stack 110 continues to move, the first cutter head 130 completes the cutting of the upper-end outer packaging film, and the second cutter head 165 completes the cutting of the lower-end outer packaging film. The bottle stack 110 after cutting leaves the cutting area and is conveyed to the next process.

[0051] The automatic film cutting device significantly reduces the time and cost of manual operation and improves the efficiency of the production line; the precise cutting reduces the possibility of bottle body damage and lowers the product damage rate; the device can adapt to different sizes of bottle stacks, improving the flexibility and adaptability of the production line.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present utility model pertains, various changes can be made without departing from the purpose of the present utility model.
