Description

Technical Field

[0001] This utility model relates to the field of pearlescent film production technology, specifically to a pearlescent film cutting device that facilitates cutter replacement. Background Technology

[0002] Pearl film is a type of plastic film with a special gloss effect. With its unique appearance and excellent performance, it is widely used in packaging, decoration, and other fields. It is typically made primarily of polyethylene (PE), with pearlescent masterbatch added during the production process through a special technique. These masterbatch particles form a uniformly distributed microstructure within the film. When light shines on the film surface, optical phenomena such as scattering and reflection occur, resulting in a soft, delicate luster similar to pearls, giving a sophisticated and elegant visual experience. In terms of performance, pearl film not only possesses good mechanical strength, tear resistance, and impact resistance, providing a certain degree of protection for the contents of the package, but also exhibits excellent barrier properties, blocking moisture and oxygen to a certain extent, extending the product's shelf life. Furthermore, it has strong printability, clearly displaying various patterns and text, further enhancing the packaging's aesthetics and information delivery. In terms of application scenarios, pearl film is found in numerous industries.

[0003] For example, patent CN216030977U discloses a keyboard light guide film cutting device, which relates to the technical field of light guide film cutting equipment. The device body has first sliding grooves installed on both sides, with a movable support movably connected between them. A second sliding groove is provided on the movable support, through which a cutter moving seat is movably mounted. A cutting plane is installed on the device body, located at the bottom of the movable support. Adsorption holes are arrayed on the cutting plane, and a vortex fan is installed inside the device body. However, in existing devices, the cutter is fixed to the drive mechanism by multiple bolts. When the cutter wears out or needs to be replaced with a different specification cutter, multiple bolts must be removed one by one, and then tightened again after replacement. This operation is cumbersome, time-consuming, affects work efficiency, and increases the labor intensity of operators. Furthermore, during the cutting of pearlescent film, no positioning structure is provided, making it prone to shifting during conveying and cutting, resulting in dimensional errors in the cut pearlescent film and affecting product quality.

[0004] Therefore, in order to solve such problems, we propose a cutting device for pearlescent film that facilitates blade replacement. Utility Model Content

[0005] The purpose of this invention is to provide a pearlescent film cutting device that facilitates cutter replacement, thereby solving the problems mentioned in the background art. In the existing device, the cutter is fixed to the drive mechanism by multiple bolts. When the cutter wears out or needs to be replaced with a different specification cutter, multiple bolts need to be removed one by one, and then tightened one by one after replacement. This operation is cumbersome, time-consuming, affects work efficiency, increases the labor intensity of operators, and, in addition, no positioning structure is set in the process of cutting pearlescent film. The pearlescent film is prone to deviation during conveying and cutting, resulting in dimensional errors in the cut pearlescent film and affecting product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pearlescent film cutting device that facilitates cutter replacement, comprising a base, side plates fixedly connected to both sides of the top of the base, a first motor fixedly connected to the top of the outer wall of the right side plate of the top of the base, a rotating rod fixedly connected to the output end of the first motor, a turntable fixedly connected to the left side of the rotating rod, an eccentric bolt fixedly connected to the left side of the turntable, a transmission rod movably connected to the eccentric bolt, a support plate movably connected to the bottom of the first slider, a housing fixedly connected to the middle of the bottom surface of the support plate, blocks fixedly connected to both outer walls of the housing, movable cavities opened in the blocks, guide rods penetrating through the blocks, inclined blocks fixedly connected to the inner side of the guide rods, a fixed rod provided inside the housing, a fixed flat-top cone fixedly connected to the top of the fixed rod, a movable flat-top cone movably connected to the outer wall of the fixed rod, and a cutter fixedly connected to the bottom of the fixed rod.

[0007] Furthermore, the fixed flat-top cone matches the inclined block, and the housing and the cutting tool are connected by the fixed flat-top cone engaging with the inclined block.

[0008] Furthermore, a fixing bolt is connected through the housing, and the fixing bolt passes through the fixing flat-top cone.

[0009] Furthermore, a limiting block is fixedly connected to the outer end of the fixing rod, and a first spring is sleeved on the outer wall of the fixing rod, with the inner end of the first spring fixedly connected to the outer end of the block.

[0010] Furthermore, a first sliding groove is provided on the inner walls of both sides of the side plate, and a first slider is fixedly connected to both ends of the outer walls of both sides of the support plate. The side plate and the support plate are slidably connected to the first slider through the first sliding groove. A second slider is uniformly fixedly connected to the outer wall of the fixing rod, and a second sliding groove is uniformly provided on the inner wall of the block. The fixing rod and the block are slidably connected to the second sliding groove through the second slider.

[0011] Furthermore, telescopic rods are evenly fixedly connected to both sides of the bottom of the support plate, a second spring is sleeved on the outer wall of the telescopic rod, and a pressure plate is fixedly connected to the bottom of the telescopic rod.

[0012] Furthermore, both sides of the top rear of the base are fixedly connected to fasteners, and rotating shafts are rotatably connected to the fasteners. A second motor is fixedly connected to the right end of the rotating shaft, and a take-up roller is fixedly connected to the rotating shaft. A guide body is fixedly connected to the inner side of the bottom of the take-up roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are: a cutting device for pearlescent film with easy-to-change cutter, which adopts a novel structural design, the specific details of which are as follows:

[0014] (1) This pearlescent film cutting device, which facilitates cutter replacement, achieves quick blade assembly and disassembly through the coordinated operation of the fixed flat-top cone, the inclined block, the guide rod, and the first spring. It eliminates the cumbersome mode of multiple bolt fixation. When replacing the blade, simply pull out the fixing bolt and lift the blade upward to move the inclined block outward synchronously, so that it disengages from the fixed flat-top cone. At this time, the fixing rod and the blade at the bottom can be removed directly. When installing a new blade, place the fixed flat-top cone at the top of the fixing rod into the housing. After releasing the guide rod, the elastic force generated by the reset of the first spring pushes the inclined block inward to precisely engage with the fixed flat-top cone. Finally, insert the fixing bolt to complete the secondary reinforcement. The entire process does not require disassembling or tightening multiple bolts one by one. The operation steps are simplified, the blade replacement time is greatly shortened, the labor intensity of the operator is effectively reduced, and the maintenance efficiency of the equipment is significantly improved.

[0015] (2) The pearl film cutting device with easy cutter replacement has a stable positioning mechanism consisting of telescopic rods on both sides of the bottom of the support plate, a second spring, and a pressure plate. Before the cutting action is performed, as the support plate moves down, the pressure plate will first contact the surface of the pearl film. At this time, the telescopic rod is squeezed and contracted, and the second spring deforms synchronously to generate continuous elastic force, which causes the pressure plate to fit tightly and compact the pearl film, avoiding the deviation of the pearl film due to force or displacement during the conveying and cutting process. At the same time, a guide body is provided on the inner side of the bottom of the take-up roller at the top rear of the base, which can form a precise guide in the pearl film conveying path. It works in conjunction with the above positioning mechanism to further ensure the positional accuracy of the pearl film during cutting. The double protection effectively reduces the dimensional error after cutting and significantly improves the consistency and quality stability of the product.

[0016] Furthermore, the side plate and the support plate form a sliding fit structure through the first sliding groove and the first slider. This design provides precise guidance for the up-and-down reciprocating motion of the support plate, effectively limiting lateral displacement during the movement and ensuring stable and smooth lifting action. The sliding connection between the fixed rod and the block through the second slider and the second sliding groove further improves the structural accuracy. During the installation of the tool and the cutting operation, it can strictly constrain the movement trajectory of the fixed rod and ensure its accurate position. The double sliding fit structure works together to provide reliable protection from overall motion stability to the positioning accuracy of local components, significantly enhancing the stability and reliability of the device operation.

[0025] 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.

[0026] This utility model provides the following technical solution: a cutting device for pearlescent film that facilitates blade replacement.

[0027] Example 1: A pearlescent film cutting device that facilitates cutter replacement. Through the synergistic action of components such as the first spring, guide rod 16, inclined block 161, and fixed flat-top cone 171, the inclined surfaces of the inclined block 161 and the fixed flat-top cone 171 are used to quickly and conveniently disassemble and assemble the cutter 18. This prevents the problem of the cutter being fixed to the drive mechanism by multiple bolts. When the cutter is worn or needs to be replaced with a different specification cutter, multiple bolts need to be removed one by one, and then tightened one by one after the replacement is completed. This operation is cumbersome, time-consuming, affects work efficiency, and increases the labor intensity of operators.

[0028] like Figure 1 - Figure 5As shown, a pearlescent film cutting device with easy-to-change cutter includes a base 1. Side plates 11 are fixedly connected to both sides of the top of the base 1. A first motor is fixedly connected to the top of the outer wall of the right side plate 11. A rotating rod is fixedly connected to the output end of the first motor. A turntable 12 is fixedly connected to the left side of the rotating rod. An eccentric bolt is fixedly connected to the left side of the turntable 12. A transmission rod 13 is movably connected to the eccentric bolt. A support plate 14 is movably connected to the bottom of the first slider. When the first motor starts, it drives the turntable 12 to rotate via the rotating rod. The eccentric bolt on the left side of the turntable 12 moves in a circular motion, which in turn drives the support plate 14 to achieve stable up-and-down reciprocating motion along the first groove of the side plate 11 via the transmission rod 13, providing the power basis for the cutting action. A housing 15 is fixedly connected to the center of the bottom surface of the device 14. Square blocks are fixedly connected to the outer walls of both sides of the housing 15.

A fixed flat-top cone 171 is fixedly connected to the top of the fixed rod 17, and a movable flat-top cone 172 is movably connected to the outer wall of the fixed rod 17. A cutter 18 is fixedly connected to the bottom of the fixed rod 17. The fixed flat-top cone 171 matches the inclined blocks 161, and the housing 15 and the cutter 18 are connected by the engagement of the fixed flat-top cone 171 and the inclined blocks 161. During normal operation, the fixed rod 17 achieves precise engagement with the housing 15 through the fixed flat-top cone 171 and the inclined blocks 161. The body 15 is connected and fixed, with a fixing bolt 19 passing through it and also passing through the fixing flat-top cone 171.

The inner walls of both sides of the side plate 11 are provided with first sliding grooves, and the two ends of the outer walls of both sides of the support plate 14 are fixedly connected with first sliders. The side plate 11 and the support plate 14 are slidably connected to the first sliders through the first sliding grooves. This structure ensures the stability of the support plate 14 in its up-and-down reciprocating movement. The outer wall of the fixing rod 17 is uniformly fixedly connected with second sliders, and the inner wall of the block is uniformly provided with second sliding grooves. The fixing rod 17 and the block are slidably connected to each other through the second sliders and second sliding grooves, which helps the fixing rod 17 to move smoothly in the block. A pearlescent film cutting device with smooth internal movement and easy blade replacement includes a base 1. Side plates 11 are fixedly connected to both sides of the top of the base 1. A first motor is fixedly connected to the top of the outer wall of the right side plate 11. A rotating rod is fixedly connected to the output end of the first motor. A turntable 12 is fixedly connected to the left side of the rotating rod. An eccentric bolt is fixedly connected to the left side of the turntable 12. A transmission rod 13 is movably connected to the eccentric bolt. A support plate 14 is movably connected to the bottom of a first slider. When the first motor starts, it drives the turntable 12 to rotate via the rotating rod. The eccentric bolt on the left side of the turntable 12 moves in a circular motion, which in turn drives the support plate 14 to achieve stable up-and-down reciprocating motion along the first groove of the side plate 11 via the transmission rod 13, providing the power basis for the cutting action.A housing 15 is fixedly connected to the center of the bottom surface of the support plate 14. Square blocks are fixedly connected to both outer walls of the housing 15. Movable cavities are formed within the square blocks. A guide rod 16 is threaded through the square blocks. A wedge block 161 is fixedly connected to the inner side of the guide rod 16. A fixing rod 17 is installed inside the housing 15. A fixed flat-top cone 171 is fixedly connected to the top of the fixing rod 17. A movable flat-top cone 172 is movably connected to the outer wall of the fixing rod 17. A cutter 18 is fixedly connected to the bottom of the fixing rod 17. The fixed flat-top cone 171 matches the wedge block 161, and the housing... The body 15 and the cutter 18 are connected by a fixed flat-top cone 171 and a wedge block 161. During normal operation of the device, the fixing rod 17 is connected and fixed to the housing 15 by the precise engagement of the fixed flat-top cone 171 and the wedge block 161. A fixing bolt 19 is connected through the housing 15 and passes through the fixed flat-top cone 171. The fixing bolt 19 passes through the housing 15 and the fixed flat-top cone 171 to form a double fixation, which greatly improves the connection strength and stability. The inner walls of both sides of the side plate 11 are provided with first sliding grooves, and the support plate 14 is provided with first sliding grooves on both sides. Both ends of the outer wall are fixedly connected to the first slider, and the side plate 11 and the support plate 14 are slidably connected to the first slider through the first slide groove. This structure ensures the stability of the support plate 14's up-and-down reciprocating movement. The outer wall of the fixing rod 17 is uniformly fixedly connected to the second slider, and the inner wall of the block is uniformly provided with the second slide groove. The fixing rod 17 and the block are slidably connected to each other through the second slider and the second slide groove, which helps the fixing rod 17 to move smoothly within the block. When changing the tool 18, the operation process is simple and efficient. After pulling out the fixing bolt 19, the guide rod 16 is pulled to make the inclined block 1 Move 61 outward to release the locking constraint with the fixed flat-top cone 171, allowing direct removal of the fixing rod 17 and the bottom tool 18. When installing a new tool 18, insert the fixing rod 17 into the housing 15, ensuring precise engagement between the fixed flat-top cone 171 and the movable flat-top cone 172. After releasing the guide rod 16, the return force of the first spring pushes the inclined block 161 to automatically reset and re-engage with the fixed flat-top cone 171. Finally, insert the fixing bolt 19 to complete the locking. The entire process allows for quick replacement and secure fixation of the tool 18 without complex operations.

[0029] Example 2: Unlike Example 1, through the coordinated action of components such as the telescopic rod 2, the second spring and the pressure plate 21, the pearlescent film can be straightened and flattened before cutting. This prevents the pearlescent film from shifting during transportation and cutting due to the lack of a positioning structure, which could lead to dimensional errors in the cut pearlescent film and affect product quality.

[0030] like Figure 6 - Figure 7As shown, telescopic rods 2 are evenly fixedly connected to both sides of the bottom of the support plate 14. A second spring is sleeved on the outer wall of the telescopic rod 2. A pressure plate 21 is fixedly connected to the bottom of the telescopic rod 2. When the support plate 14 descends for cutting, the pressure plate 21 will first contact the pearlescent film. At this time, the telescopic rod 2 retracts, the second spring is compressed and generates elastic force, so that the pressure plate 21 presses the pearlescent film firmly. Fixing components are fixedly connected to both sides of the top rear of the base 1. A rotating shaft is rotatably connected to the fixing component. A second motor is fixedly connected to the right end of the rotating shaft. A take-up roller 3 is fixedly connected to the rotating shaft. When the second motor starts, it will drive the rotating shaft to rotate, thereby causing the take-up roller 3 to rotate, realizing the release of the pearlescent film before cutting. A guide body 31 is fixedly connected to the inner side of the bottom of the take-up roller 3. During the release of the pearlescent film, the guide body 31 can play a guiding role to ensure neat release. When the support plate 14 moves up and down, it drives the housing 15 and the cutter 18 below to move synchronously to realize the cutting action of the pearlescent film. During the cutting process, the cutter 18 then completes the cutting.

[0031] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
