Technical Field
[0001] The utility model relates to the technical field of film slitting, in particular to a slitting mechanism of a decorative film slitting machine. Background Art
[0002] Decorative film is widely used in architectural decoration, furniture decoration and automobile interior decoration. It can provide beautiful decorative effects for various surfaces and also has a protective effect. In architectural decoration, decorative film can be used for the decoration of walls, doors and windows to increase the beauty of the interior. In furniture decoration, film can be used to cover the surface of furniture to protect it from wear and scratches. As people's requirements for quality of life continue to increase, the demand for decorative film is also increasing. In the film production process, a slitting machine is needed to cut it.
[0003] Traditional slitting mechanisms usually use a single power source to directly drive the slitting blades, which makes it difficult to ensure the synchronous lifting and lowering of multiple slitting blades. This means that only one layer of film can be processed at a time. If multiple layers of film need to be processed, the slitting process needs to be repeated many times, which greatly reduces work efficiency. At the same time, since only one group of slitting blades is working, problems such as uneven pressure and inaccurate cutting will occur during the slitting process, resulting in uneven edges of the slitting film. In view of the above problems, a slitting mechanism for a decorative film slitting machine is proposed. Utility Model Content

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] As Figures 1 - 5 shown, the present invention provides a technical solution: a slitting mechanism for a decorative film slitter, including a processing table 1. A partition board 101 is fixedly connected to the inner wall of the processing table 1. Limit strips 102 are fixedly connected to both sides of the top of the processing table 1. A scale 103 is arranged on one side of the limit strip 102, and the scale 103 is fixed to the outer surface of the processing table 1. A slitting groove 104 is penetrated and opened on the outer side of the top of the processing table 1. A driving motor 2 is fixedly connected to the inner bottom end of the processing table 1. A driving gear 201 is movably connected to the top of the driving motor 2. Driven gears 202 are movably connected to both sides of the driving gear 201. A lead screw 203 is movably connected to the top of the driven gear 202. A nut block 204 is movably connected to the outer surface of the lead screw 203. A movable block 205 is movably connected to the outer side of the top of the nut block 204. A placing strip 206 is fixedly connected to the outer surface of one side of the movable block 205. A slitting blade 207 is fixedly connected to the bottom of the placing strip 206. A guide block 208 is fixedly connected to the outer wall of the other side of the placing strip 206. A guide rod 209 is slidably connected to the inner wall of the guide block 208. A vertical rod 3 is fixedly connected to the top of the processing table 1. The vertical rods 3 are symmetrically distributed with respect to a group of limit strips 102. A slide groove 301 is vertically opened on the inner wall of the vertical rod 3. A guide strip 302 is fixedly connected to the inner surface of one side of the slide groove 301. A slide block 303 is movably connected to the outer surface of the guide strip 302. A holding rod 304 is fixedly connected to the outer surface of one end of the slide block 303. A pressing strip 305 is fixedly connected to the outer surface of the other end of the slide block 303.
[0025] According to the overall structure of the device, when the device is in use, the staff first place the decorative film to be slit on the top of the processing table 1, aligning its two side edges with the limit strips 102. At the same time, the scale 103 facilitates the staff to determine the slitting size of the film. After the decorative film is placed on the processing table 1, at this time, the pressing strip 305 is in the initial position above the processing table 1. The operator holds the grip 304 and applies downward pressure. The grip 304 is fixedly connected to the slider 303. When the grip 304 receives a downward force, it drives the slider 303 to move downward in the chute 301 of the vertical rod 3. The guide strips 302 symmetrically distributed on both sides of the inner wall of the chute 301 are slidably connected to the slider 303, providing stable guidance for the up and down movement of the slider 303. As the slider 303 descends, the pressing strip 305 fixedly connected to the outer surface of the other end of the slider 303 also descends. When the pressing strip 305 contacts the film, continue to apply downward pressure to tightly press the film against the processing table 1 by the pressing strip 305. After the pressing strip 305 presses the film against the processing table 1, it prevents the film from shifting or wrinkling during the slitting process, preparing for the accurate slitting of the film by the slitting blade 207 through the slitting groove 104. Then, start the drive motor 2. The top of the motor drives the driving gear 201 to rotate. The driving gear 201 meshes with the driven gear 202 to drive the two driven gears 202 on both sides to rotate simultaneously. When the driven gear 202 rotates, it drives the lead screw 203 connected to the top to rotate. The nut block 204 on the outer surface of the lead screw 203 meshes with the lead screw 203 through the inner wall and performs a lifting motion as the lead screw 203 rotates. When the nut block 204 moves up and down, the bottom of the movable block 205 rotates following the nut block 204, and the movable block 205 at the top moves up and down following the bottom, keeping its position unchanged. The bottom of the movable block 205 is rotatably connected between the nut block 204 and the top of the movable block 205, enabling the movable block 205 to move up and down together with the nut block 204. The placement strip 206 on the outer wall of the movable block 205 and the slitting blade 207 at the bottom also move up and down as the movable block 205 moves up and down. When the slitting blade 207 descends, it passes through the slitting groove 104 to slit the film placed on the processing table 1. During the lifting and lowering process of the slitting blade 207, the guide block 208 fixed to the outer wall of the other side of the placement strip 206 slides along the guide rod 209. The hole groove opened inside the guide block 208 is used to sleeved on the guide rod 209, ensuring the stability of the slitting blade 207 during the lifting and lowering process and guaranteeing the accuracy and quality of the slitting. Through the control of the drive motor 2, the slitting blade 207 descends to the specified position and passes through the slitting groove 104 to slit the film. The two slitting grooves 104 divide the processing table 1 into three blocks of the same length, enabling multiple slittings of the film simultaneously, thereby improving the slitting efficiency.
[0026] As Figures 1 - 5As shown in the figure, the top end of the driving motor 2 penetrates through the partition plate 101 and is rotatably connected to the driving gear 201. The bottoms of the driving gear 201 and the driven gear 202 are both rotatably connected to the top end of the partition plate 101, and the driven gears 202 are symmetrically distributed on both sides of the driving gear 201. The driven gear 202 and the driving gear 201 are in meshing transmission. The lead screw 203 is rotatably connected to the top end of the driven gear 202. The inner wall of the nut block 204 and the outer side of the lead screw 203 are in meshing transmission. The movable block 205 is composed of two sets of hollow cylindrical rings that are rotatably connected to each other up and down. The bottom end of the movable block 205 is rotatably connected to the top of the nut block 204. The movable block 205 and the nut block 204 form a lifting structure through the cooperation among the lead screw 203, the driven gear 202, and the driving gear 201. The slitting blade 207 and the slitting groove 104 form a lifting structure through the cooperation of the placing strip 206 and the movable block 205. The slitting groove 104 and the slitting blade 207 are set as a group, and the vertical center lines between the slitting groove 104 and the slitting blade 207 are the same. The slitting grooves 104 are evenly distributed along the top of the processing table 1. The two slitting grooves 104 divide the processing table 1 into three blocks of the same length. Both ends of the slitting groove 104 are opened inside the limiting strip 102. A hole groove is vertically penetrated through the center of the inside of the guiding block 208, and the outer wall of the bottom end of the guiding rod 209 is fixed to the top end of the processing table 1.
[0027] The driving motor 2 drives the driving gear 201 to rotate at the top end. The driving gear 201 and the driven gear 202 are in meshing transmission, so as to drive the driven gears 202 on both sides to rotate simultaneously. When the driven gear 202 rotates, it drives the lead screw 203 connected to the top end to rotate. The nut block 204 on the outer surface of the lead screw 203 moves up and down with the rotation of the lead screw 203 through the meshing transmission between the inner wall and the lead screw 203. When the nut block 204 moves up and down, the bottom of the movable block 205 rotates following the nut block 204, and the movable block 205 at the top follows the bottom to move up and down and keeps its position unchanged. The bottom of the movable block 205 is rotatably connected between the nut block 204 and the top of the movable block 205, so that the movable block 205 moves up and down together with the nut block 204. The placing strip 206 on the outer wall of the movable block 205 and the slitting blade 207 at the bottom also move up and down with the lifting of the movable block 205. When the slitting blade 207 descends, it passes through the slitting groove 104 to slit the film placed on the processing table 1. During the lifting process of the slitting blade 207, the guiding block 208 fixed to the outer wall of the other side of the placing strip 206 slides along the guiding rod 209. The hole groove opened inside the guiding block 208 is used to sleeved on the guiding rod 209, ensuring the stability of the slitting blade 207 during the lifting process, guaranteeing the precision and quality of the slitting. Through the control of the driving motor 2, the slitting blade 207 descends to the specified position and passes through the slitting groove 104 to slit the film. The two slitting grooves 104 divide the processing table 1 into three blocks of the same length, and multiple slittings of the film can be realized simultaneously, thereby improving the slitting efficiency.
[0028] As Figures 1 - 5 shown, the chute 301 is opened at the inner center of the vertical rod 3. The guiding strips 302 are symmetrically distributed on both sides of the inner wall of the chute 301. The guiding strips 302 are slidably connected to the slider 303. The pressing strip 305 forms a lifting structure with the processing table 1 through the cooperation of the slider 303 and the guiding strips 302. The outer side of the pressing strip 305 and the outer side of the processing table 1 are arranged on the same horizontal plane. The outer wall diameter of the pressing strip 305 is smaller than the inner wall diameter between a group of limiting strips 102.
[0029] The grip rod 304 is fixedly connected to the slider 303. When a downward force is applied to the grip rod 304, the slider 303 is driven to move downward in the chute 301 of the vertical rod 3. The guiding strips 302 symmetrically distributed on both sides of the inner wall of the chute 301 are slidably connected to the slider 303, providing stable guidance for the up and down movement of the slider 303. As the slider 303 descends, the pressing strip 305 fixedly connected to the outer surface of the other end of the slider 303 also descends. When the pressing strip 305 contacts the film, continue to apply downward pressure to make the pressing strip 305 tightly press the film on the processing table 1. After the pressing strip 305 presses the film on the processing table 1, it prevents the film from shifting or wrinkling during the slitting process, preparing for the slitting blade 207 to accurately slit the film through the slitting groove 104.
[0030] Working principle: When the device is in use, the staff first place the decorative film to be slit on the top of the processing table 1, aligning its two side edges with the limit strips 102. At the same time, the scale 103 facilitates the staff to determine the slitting size of the film. Then, start the drive motor 2. The top of the motor drives the driving gear 201 to rotate. The driving gear 201 meshes with the driven gear 202 to drive the two driven gears 202 to rotate simultaneously. When the driven gear 202 rotates, it drives the screw rod 203 connected to its top to rotate. The nut block 204 on the outer surface of the screw rod 203 is in meshing transmission with the screw rod 203 through its inner wall and performs a lifting motion as the screw rod 203 rotates. When the nut block 204 moves up and down, the bottom of the movable block 205 rotates following the nut block 204, and the movable block 205 at the top moves up and down following the bottom while keeping its position unchanged. The bottom of the movable block 205 is rotatably connected between the nut block 204 and the top of the movable block 205, enabling the movable block 205 to move up and down together with the nut block 204. The placement strip 206 on the outer wall of the movable block 205 and the slitting blade 207 at the bottom also move up and down with the movable block 205. When the slitting blade 207 descends, it passes through the slitting groove 104 to slit the film placed on the processing table 1. During the up and down movement of the slitting blade 207, the guiding block 208 fixed to the outer wall on the other side of the placement strip 206 slides along the guiding rod 209. The hole groove opened inside the guiding block 208 is used to sleeved on the guiding rod 209, ensuring the stability of the slitting blade 207 during the up and down movement and guaranteeing the accuracy and quality of the slitting. Through the control of the drive motor 2, the slitting blade 207 descends to the specified position and passes through the slitting groove 104 to slit the film. The two slitting grooves 104 divide the processing table 1 into three blocks of the same length, enabling multiple slittings of the film simultaneously, thereby improving the slitting efficiency.
[0031] After the decorative film is placed on the processing table 1, at this time, the pressing strip 305 is at the initial position above the processing table 1. The operator holds the grip 304 and applies a downward pressure. The grip 304 is fixedly connected to the slider 303. When the grip 304 receives a downward force, it drives the slider 303 to move downward in the chute 301 of the vertical rod 3. The guiding strips 302 symmetrically distributed on both sides of the inner wall of the chute 301 are slidably connected to the slider 303, providing stable guidance for the up and down movement of the slider 303. As the slider 303 descends, the pressing strip 305 fixedly connected to the outer surface of the other end of the slider 303 also descends. When the pressing strip 305 touches the film, continue to apply a downward pressure to make the pressing strip 305 tightly press the film on the processing table 1. After the pressing strip 305 presses the film on the processing table 1, it prevents the film from shifting or wrinkling during the slitting process, preparing for the accurate slitting of the film by the slitting blade 207 through the slitting groove 104.
