Description

Technical Field

[0001] This utility model relates to the field of label processing equipment, and in particular to a cutting device for label processing. Background Technology

[0002] Label products are widely used in various fields such as product packaging, logistics tracking, and information identification. In particular, self-adhesive labels have become the mainstream label material type due to their ease of use and strong adhesion.

[0003] In actual processing, the adhesives used in self-adhesive labels have significant temperature-sensitive characteristics and are easily affected by frictional heat. At both room temperature and high temperatures, frequent contact between the cutting blade and the label material generates frictional heat, leading to increased activity and fluidity of the adhesive molecules, resulting in adhesion at the moment of cutting. This adhesion not only causes the label edges to stick to the blade, affecting cutting quality, but also leads to adhesive buildup on the blade surface, causing equipment jamming, frequent downtime for maintenance, and other problems, severely restricting processing efficiency and product consistency. Furthermore, existing cutting devices generally use fixed-installation cutting blades, requiring cumbersome disassembly steps and specialized tools. Once the blades accumulate adhesive or wear and require replacement or maintenance, prolonged downtime is necessary, impacting the overall production line efficiency. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To achieve the above-mentioned utility model objectives, such as Figure 1-6 As shown, this utility model provides a label processing cutting device, including: a frame 1, a conveyor belt 3 is provided on one side of the inner wall of the frame 1, a cutting base 14 is fixedly installed on the side of the inner wall of the frame 1 near the conveyor belt 3, a plurality of second guide shafts 10 are rotatably arranged on the side of the inner wall of the frame 1 near the cutting base 14 at intervals, a second drive shaft 9 is rotatably installed on the upper end of each second guide shaft 10, and a plurality of cooling plates 6 are fixedly installed between the plurality of second guide shafts 10;

[0030] A first drive shaft 8 is rotatably mounted on one side of one of the cooling plates 6 on the inner wall of the frame 1. A first guide shaft 7 is rotatably mounted on the upper end of the first drive shaft 8. A cutting device 2 is fixedly installed in the middle of the top surface of the frame 1. A guide plate 12 is fixedly mounted on one side of the outer wall of the frame 1. A collection frame 11 is fixedly mounted on the other side of the inner wall.

[0031] The cutting device (2) is installed on the top surface of the frame (1) at the middle position via a fixing frame (21). The fixing frame (21) is symmetrically arranged on both sides to provide stable support for the cutting device (2). A cylinder (26) is fixedly installed at the center of the lower end of the inner wall of the fixing frame (21). The cylinder (26) is connected to an external high-pressure air source to realize the telescopic drive function. A connecting shaft (23) is fixedly connected to the top of its telescopic rod. The top of the connecting shaft (23) is provided with an arc structure. Limiting grooves are opened near the two sides. The limiting grooves cooperate with the limiting blocks (24) that are slidably arranged in the inner sliding groove of the top of the cutting blade (22) to realize the limiting installation of the cutting blade (22). When the cylinder (26) drives the connecting shaft (23) to extend into the top sliding groove of the cutting blade (22), the limiting blocks (24) are squeezed by the arc structure at the top of the connecting shaft (23) and retract along the sliding groove direction. The spring (25) located inside the slide groove is compressed. When the connecting shaft (23) continues to push inward and reaches the position of the limiting groove, the spring (25) resets and pushes the limiting block (24) into the limiting groove, thereby realizing the quick locking and fixing of the cutting blade (22). When it is necessary to disassemble and replace the cutting blade (22), the operator only needs to hold the blade with both hands and use his thumb to push the outer end of the limiting block (24) extending from the top through groove of the cutting blade (22), so that it overcomes the elastic force of the spring (25) and slides away from the limiting groove along the slide groove direction to realize the unlocking operation. Then, the cutting blade (22) is pulled down to complete the disassembly, maintenance or replacement operation. The operation is convenient and requires no tools.

[0032] The first guide shaft 7 guides and limits the label material conveyed by the guide tray 12, ensuring the label remains stable before entering the processing area. After being guided by the first guide shaft 7, the label is powered by the first drive shaft 8 below it, moving the label forward along the cooling plate 6, passing through multiple cooling zones composed of second guide shafts 10 and second drive shafts 9, achieving double-sided cooling. After cooling, the label continues forward, entering the second drive shaft 9 on one side of the cutting device 2, and is then conveyed to the cutting base 14 for cutting. The cut labels are output to the collection frame 11 via the conveyor belt 3, realizing the automated and efficient execution of the entire label cutting process.

[0033] A third pulley is located at the top of one side of the first drive shaft 8. This third pulley is driven to rotate by the first motor 4 and is connected to the second pulley 91 via an internally connected first belt 41, causing the second pulley 91 to rotate in the same direction. The second pulley 91 drives the connected second drive shaft 9, controlling the conveying of label material within the guide tray 12 and ensuring its stable operation along a preset trajectory. A second belt 92 is installed in the connecting groove on the other side of the second pulley 91. The other end of the second belt 92 is connected to the first pulley 13, used to synchronously drive another second drive shaft 9, ensuring that the two second drive shafts 9 rotate in tandem, further improving the stability and continuity of the label conveying and cutting process.

[0034] The cooling plate 6 is made of all-copper material and has excellent heat conduction performance. It has a circulation pipe 61 inside, which is connected to the external cooling device to form a closed circulation system. When the label material is conveyed above the cooling plate 6, its surface can be cooled down quickly, effectively reducing the adhesive stickiness and preventing sticking to the blade during subsequent cutting, thus improving overall processing efficiency and product yield.

[0035] The working principle of this utility model is as follows: During operation, the first motor 4 drives the third pulley, which in turn drives the first transmission shaft 8 to rotate. The third pulley contains a first belt 41, which is connected to the second pulley 91, thereby driving the second transmission shaft 9 to rotate synchronously. The other end of the second transmission shaft 9 is connected to the first pulley 13 via a second belt 92, ensuring that the second transmission shaft 9 on the other side also receives driving force, forming a double-sided linkage transmission structure. The rotation of the first transmission shaft 8 simultaneously drives the first guide shaft 7 located below it, thus controlling the label material conveyed by the guide tray 12. The label material is guided, limited, and conveyed forward. It first moves forward along the first guide shaft 7, then sequentially enters the conveying path above the first and second cooling plates 6. The cooling plates 6 have internal circulation pipes 61 connected to an external cooling device, continuously cooling the passing label material, reducing the adhesive surface temperature, decreasing the likelihood of adhesion to the blades, and ensuring the continuity and smoothness of subsequent cutting processes. The second guide shafts 10 on both sides are spaced apart on the inner wall of the frame 1, rotatably connected to the inner wall of the frame 1 via rotating shafts 101, providing stable support and guidance for the second drive shaft 9. As the second drive shaft 9 rotates, the label material is continuously fed forward along the cooling path and finally conveyed to the cutting base 14 area located inside the frame 1. After the label material reaches the cutting position, the cutting device 2 performs the cutting operation. The cutting blade 22, driven by the cylinder 26, rapidly presses down vertically to cut the label. The cut label is then conveyed via the conveyor belt 3 to the collection frame 11 located on the side of the frame 1 for recycling.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
