Description

Technical Field

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

[0002] The energy storage film, also called the film that glows in the dark, is usually used in low-light or dark environments where visibility is important, and can provide a reliable and energy-saving solution for lighting signs, markings and other objects, such as safety signs, emergency exit signs, decorations and novelty products, etc. The development of energy storage film technology enables the creation of more efficient and durable materials, providing long-lasting lighting. The energy storage film usually contains phosphorescent or fluorescent materials, which absorb and store energy from ambient light or other light sources, and then slowly release the energy in the form of visible light over time. After the energy storage film is produced through multiple coating processes, it usually needs to be cut. First, the two side edges of the whole roll of energy storage film need to be cut off to make the head and tail of the whole roll of energy storage film flat. After the head and tail are cut flat, the film roll material is placed on the film cutting machine and cut into energy storage films of various specifications and sizes.

[0003] Due to the production process and the energy storage film material, the existing film cutting machines are prone to generate waste materials such as luminous powder debris during the cutting process. The waste materials are easily adhered to the surface of the energy storage film after cutting, affecting the appearance and performance of the product, such as reduced luminous amount and appearance defects. The luminous powder is also a toxic substance. If the production personnel accidentally inhale or get the luminous powder on them, it will seriously affect their health.

[0042] The following is a detailed description through specific embodiments.

[0043] As Figures 1 to 2 shown, an embodiment of the present utility model provides a film cutting machine, which includes a fixing device 100 and a cutting device 200 arranged on the upper part of the fixing device 100. The cutting device 200 is used to cut the film on the fixing device 100. The cutting device 200 includes a cutting knife 210 and a waste collection member 220 arranged outside the cutting knife 210;

[0044] The waste collection member 220 is a sleeve sleeved outside the cutting knife 210. An undulating structure and a pore structure are arranged on the inner wall of the waste collection member 220. The undulating structure is used to increase the surface area of the inner wall, and the pore structure is used for physically adsorbing the waste generated by cutting.

[0045] Specifically, four connectors 212 are provided on the cutting knife 210 to detachably connect the waste collection member 220 to the cutting knife 210. After the waste collection member 220 is full of adsorption, it can be detached, cleaned, and reused or replaced with a new one. The waste collection member 220 is made of carbon, a material with high adsorption capacity, and is specially treated to increase its surface area and adsorption performance. The carbon material is mainly activated carbon, which is a porous carbon. Structurally, due to the irregular arrangement of microcrystalline carbon, there are fine pores between the cross-connections, with the characteristics of low bulk density and large specific surface area. It is also the main material of the filter, which can adsorb and remove some substances in gases, liquids, and solids, playing a role in purification, refining, or recovery. Since the fine pores of activated carbon are micro-pores and can only adsorb very small substances, the waste collection member 220 needs to be specially treated. A pore structure is added to its inner wall, such as grooves, scratches, or concave holes on the inner wall, for adsorbing and accommodating larger substances and improving the effect of waste adsorption. On the other hand, a undulating structure is also provided on the inner wall of the waste collection member 220. For example, the undulating structure in this embodiment is wavy, which can significantly increase the contact surface between the inner wall and the waste and improve the effect of waste adsorption.

[0046] As Figure 3 shown, in this embodiment, the cutting knife 210 is in the shape of a pyramid, and a discharge groove 211 is provided on the side surface of the cutting knife 210. The discharge groove 211 is used to guide the waste generated by cutting onto the waste collection member 220.

[0047] Specifically, the cutting knife 210 is a pyramid with a square bottom surface, the vertex is the contact point of the cutting film, and the side surfaces are multiple irregular inclined surfaces. At least one discharge groove 211 is provided on each side surface to ensure that when the cutting knife 210 cuts from any direction, the waste debris can be discharged from the discharge groove 211.

[0048] In this embodiment, one end of the discharge groove 211 faces the vertex of the cutting knife 210, and the other end is bent and extends to the side edge of the cutting knife 210 to form an opening, and the opening positions on adjacent side surfaces are staggered.

[0049] Specifically, the discharge groove 211 is an arc-shaped line segment, one end faces the vertex but does not contact the vertex, and the other end is bent and contacts the side edge of the side surface, and an opening is formed at the side edge. The waste generated during cutting is generated from the vertex and is splashed onto the waste collection member 220 outside the cutting knife 210 along the direction of the discharge groove 211. As Figure 3 shown, it can be seen that multiple discharge grooves 211 are distributed on each side surface, and the opening positions on adjacent side surfaces are staggered. The advantage of this design is that when the cutting knife 210 cuts from any direction, the waste can be guided along the discharge groove 211 to the waste collection member 220.

[0050] As Figure 4As shown, in this embodiment, the cutting device 200 further includes a housing 230, an adjusting member 240, and a locking member 250. The cutting knife 210 and the waste collection member 220 are arranged on the housing 230. The adjusting member 240 is a threaded member, and the overall length of the cutting device 200 is controlled according to the length of the adjusting member 240 inserted into the housing 230. The locking member 250 is sleeved on the locking member 250 and is used to fix the housing 230 and the adjusting member 240.

[0051] Specifically, by rotating the adjusting member 240, the length of the adjusting member 240 inserted into the housing 230 is adjusted, and then the overall height of the cutting device 200 is controlled to cut films of different thicknesses. After adjusting the height, by rotating the locking member 250, the locking member 250 is brought into contact with the housing 230 to lock the height. The pressing member 260 is connected to the bottom surface of the cutting knife 210. By default, the cutting knife 210 retracts into the waste collection member 220. Press the pressing member 260 to make the cutting knife 210 extend out of the waste collection member 220 for cutting work.

[0052] In this embodiment, the cutting device 200 further includes a heating component 270 and an antistatic component 280. The heating component 270 is connected to the cutting knife 210 and is used to heat the cutting knife 210. The antistatic component 280 is arranged around the cutting knife 210 and is used to remove static electricity.

[0053] Specifically, heating the cutting knife 210 can make the film easier to cut, reduce the friction during cutting, and thus improve the cutting efficiency and quality. The antistatic component 280 can remove the static electricity generated during cutting, prevent production personnel from being shocked by static electricity, and can also eliminate the static electricity on the film to make the film more compliant. Both the heating component 270 and the antistatic component 280 are arranged on the housing 230.

[0054] As Figure 1 shown, in this embodiment, the film cutting machine further includes a cutting device displacement mechanism 300. The cutting device displacement mechanism 300 includes a cross bar 310 and sliders 320 arranged at both ends of the cross bar 310. The cutting device 200 is arranged to move on the cross bar 310, and the sliders 320 drive the cross bar 310 and the cutting device 200 to move together on the fixing device 100.

[0055] Specifically, the cutting device 200 is installed on the slide rail of the cross bar 310 and moves along the X-axis. The cutting device 200 and the cross bar 310 move along the Y-axis together with the sliders 320 on the slide rail. The sliders 320 are arranged on both sides of the film on the adsorption platform 120. The cutting device 200 and the cross bar 310 are arranged above the film. Therefore, the cutting device 200 can freely move on the film plane to cut the film into various shape patterns. The adjusting member 240 is connected to the slide rail of the cross bar 310. The height of the cross bar 310 remains unchanged. By adjusting the overall height of the cutting device 200, the distance between the cutting knife 210 and the adsorption platform 120 is controlled, and then films of different thicknesses are cut.

[0056] As Figure 5 shown, in this embodiment, the fixing device 100 includes an adsorption platform 120 with suction holes 110 formed on its surface. The suction holes 110 are used to adsorb and fix the film to be cut on the adsorption platform 120.

[0057] Specifically, the adsorption platform 120 is a cuboid, and the suction holes 110 are through holes that penetrate the adsorption platform 120 along the Z-axis direction. The number of suction holes 110 is very large and is distributed according to the shape of the film to be cut, usually in an equidistant regular planar matrix; the smaller the spacing, the denser the suction holes 110, the better the adsorption effect, and the less likely the surface of the film is to be deformed by force. Many small suction cups corresponding to the suction holes 110 one by one are arranged at the bottom of the adsorption platform 120. The small suction cups are connected to a vacuum pump through air pipes. The small suction cups are made of polyurethane. Such small suction cups are very suitable for grasping products with rough surfaces and have oil resistance. Each small suction cup controls the opening and closing of one suction hole 110. Each small suction cup can be opened or closed independently to achieve zonal adsorption to suit different cutting shape patterns. For example, all the suction holes 110 are initially opened to adsorb the entire surface of the film to be cut on the adsorption platform 120; after the cutting device 200 finishes cutting, the suction holes 110 covered by the cutting shape pattern are independently closed, and the other suction holes 110 remain open. At this time, the cut film is not adsorbed, which is convenient for the moving device 600 to suck and move; after the moving device 600 moves away all the cut films, the suction holes 110 are all closed again, which is convenient for the winding roller 400 to replace the new film. The film is firmly adsorbed on the adsorption platform 120 by evacuating through the suction holes 110. Cooperating with the pulling force of the winding roller 400 and the unwinding roller 500 on the film coil, the flatness of the surface of the film to be cut can be ensured and it is convenient for the cutting device 200 to position.

[0058] As Figure 7 shown, in this embodiment, the film cutting machine further includes a winding roller 400 and an unwinding roller 500 respectively arranged on both sides of the fixing device 100. A film coil is installed on the unwinding roller 500, and the winding roller 400 is used to wind up the beginning of the film coil to drive the film coil to move on the fixing device 100.

[0059] Specifically, the film roll stock is similar to a hollow cylindrical roll of paper. The film roll stock is rotatably sleeved on the unwinding roller 500. The beginning part of the roll stock is wound around the winding roller 400 after passing over the adsorption platform 120. At this time, the film to be cut is laid on the adsorption platform 120. After the cutting device 200 cuts the film and the moving device 600 moves the cut film away, all the suction holes 110 of the adsorption platform 120 are temporarily closed; the winding roller 400 rotates to drive the film on the adsorption platform 120 to move in the Y-axis direction until the film on the adsorption platform 120 is replaced with a new film to be cut, then the winding roller 400 stops rotating; all the suction holes 110 of the adsorption platform 120 are reopened to start the next round of cutting. If only relying on the pulling force of the winding roller 400 and the unwinding roller 500 on the film roll stock without the suction force of the suction holes 110 of the adsorption platform 120, the film cannot be laid flat on the fixing device 100, and problems such as wrinkles and offsets are likely to occur, and precise positioning cannot be achieved.

[0060] Specifically, a protective cover is provided above both the winding roller 400 and the unwinding roller 500 to protect the film roll stock from external impacts and interference from other objects.

[0061] As Figure 1 shown, in this embodiment, the film cutting machine further includes a moving device 600. The moving device 600 includes a suction head 610, a first slide rail 620, a connecting rod 630, and a second slide rail 640. The suction head 610 is arranged to move on the first slide rail 620. One end of the connecting rod 630 is fixedly connected to the first slide rail 620, and the other end is arranged to move on the second slide rail 640. The second slide rail 640 is arranged on the side of the fixing device 100. The suction head 610 is used to adsorb and move the cut film away from the fixing device 100.

[0062] Specifically, the moving device 600 includes a plurality of suction heads 610. A plurality of suction heads 610 are fixed on the first slide rail 620 through a flat suction head base. The suction head base drives the plurality of suction heads 610 to move along the Y-axis on the first slide rail 620. The plurality of suction heads 610 and the first slide rail 620 move along the Z-axis on the second slide rail 640 together with the connecting rod 630. The lower half of the second slide rail 640 is fixed on the side of the fixing device 100. The length of the connecting rod 630 is used to make the suction head 610 float above the adsorption platform 120. The suction head 610 is used to suck and move the cut finished film away from the adsorption platform 120.

[0063] As Figure 6As shown, in this embodiment, the film cutting machine also includes a collecting device 700, which includes two first push rods 710, a second push rod 720 and a collecting bag 730. The two first push rods 710 and the second push rods 720 form a collecting area. The moving device 600 is used to move the cut film to the collecting area for stacking. The two first push rods 710 push the film to a preset position from both sides, and the second push rod 720 pushes the film into the collecting bag 730 from the other side.

[0064] Specifically, the moving device 600 moves the cut film to the collection area for stacking. After the film is stacked to a preset number of layers, the two first push rods 710 push and merge the films from both sides along the X-axis direction to make the films neatly stacked. Then the second push rod 720 pushes the merged finished film into the collection bag 730 from the other side along the Y-axis direction, and finally seals and packs the film. The collection bag 730 is fully opened on the support rod of the collection device 700, and the bag opening of the collection bag 730 is open toward the Y-axis direction. Each first push rod 710 is pushed by two sub-rods 740, and the second push rod 720 is also pushed by two sub-rods 740. In the process of pushing, the first push rod 710 will resist the sub-rod 740 of the second push rod 720 from the side direction, that is, the distance between the two first push rods 710 can be controlled by controlling the length of the second push rod 720. This distance (i.e., the length of the second push rod 720) is determined according to the size of the product film, and generally speaking, the distance is slightly larger than the size of the product film. The collecting device 700 is arranged beside the fixing device 100, and the first slide rail 620 of the moving device 600 spans the collecting device 700 and the fixing device 100, that is, the first slide rail 620 can move the finished film from the adsorption platform 120 to the collecting area. In this embodiment, the two first push rods 710 are perpendicular to the second push rod 720, and the two first push rods 710 are parallel to each other, so the enclosed collecting area is a rectangular area.

[0065] In summary, the film cutting machine of the utility model can collect waste generated during cutting by arranging a waste collecting piece 220 on the outside of the cutter 210, thereby reducing damage caused by waste entering the gap of the film cutting machine due to excessive waste, appearance problems and performance problems caused by waste sticking to the film surface, and safety problems posed by toxic waste to production personnel; through the undulating structure and the pore structure, the adsorption surface area and physical adsorption effect of the waste collecting piece 220 are increased, which has the advantages of simple structure, low cost, and easy replacement.

[0066] In addition, a discharge groove 211 structure is provided on the side of the cutter 210. One end of the discharge groove 211 faces the top of the cutter 210, and the other end is bent and extends to the side of the cutter 210 to form an opening. The opening positions on adjacent sides are staggered, which helps to efficiently guide the waste to splash onto the waste collection piece 220.

[0067] Moreover, the cutting device 200 further includes a housing 230, an adjusting member 240, and a locking member 250. The overall length of the cutting device 200 is controlled according to the length of the adjusting member 240 inserted into the housing 230, thereby controlling the height of the cutting blade 210 for cutting films of different thicknesses.

[0068] Moreover, the cutting device 200 further includes a heating component 270 and an anti-static component 280. The heated cutting blade 210 cuts more smoothly and can reduce the generation of waste. The anti-static component 280 can prevent production personnel from being electrocuted by static electricity and can eliminate the static electricity on the film, making the film more compliant.

[0069] Moreover, the film cutting machine further includes a cutting device displacement mechanism 300, a moving device 600, and a collecting device 700. The film cutting machine has a high degree of automation and high production efficiency.

[0070] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto.
