DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:
[0022] like Figure 1As shown, the utility model provides a facing paper cutting device that is convenient for replacing the cutting knife, including a base 101, the four corners of the bottom of the base 101 are fixedly connected to the support legs 102, the top of the base 101 is fixedly connected to the support frame 103, the top of the support frame 103 is fixedly connected to the positioning component 2, the bottom of the positioning component 2 is fixedly connected to the facing paper fixing component 3, and the bottom of the facing paper fixing component 3 is fixedly connected to the cutting knife replacement component 4.
[0023] The base 101 is stably supported on the ground by four legs 102. The support frame 103 is fixed on the top of the base 101 to provide support for the positioning component 2. The positioning component 2 can move precisely in the left and right directions. The facing paper fixing component 3 is used to fix the facing paper and can adjust the position. The cutting knife replacement component 4 can easily replace the cutting knife 413.
[0024] like Figure 2 As shown, the positioning assembly 2 includes two side plates 201, the bottoms of the left and right side plates 201 are fixedly connected to the top of the support frame 103, and the opposite surfaces of the left and right side plates 201 are fixedly connected to two front and rear symmetrical sliding rods 203. A rack 202 fixedly connected to the top of the support frame 103 is provided between the left and right side plates 201, and the outer walls of the front and rear sliding rods 203 are slidably connected to sliding sleeves 204, and the rear side wall of the rear sliding sleeve 204 is fixedly connected to motor 1 205. The opposite surfaces of the front and rear sliding sleeves 204 are rotatably connected to the rotating shaft 206, and the rear end of the rotating shaft 206 passes through the rear side wall of the rear sliding sleeve 204 and is fixedly connected to the output end of motor 1 205. The outer wall of the rotating shaft 206 is fixedly connected to a gear 207, and the bottom of the gear 207 is meshed with the rack 202. The tops of the front and rear sliding sleeves 204 are fixedly connected to a fixed plate 208.
[0025] When the cutting knife 413 needs to be adjusted to the left and right positions, the motor 205 is started, driving the rotating shaft 206 to rotate, so that the gear 207 fixed on the rotating shaft 206 rolls on the rack 202. Due to the meshing action of the gear 207 and the rack 202, the front and rear sliding sleeves 204 slide left and right on the slide bar 203, thereby driving the fixed plate 208 and the facing paper fixing assembly 3 and the cutting knife replacement assembly 4 installed thereon to move in the left and right directions, thereby achieving precise adjustment of the cutting position and ensuring accurate cutting of the facing paper. At the same time, the cutting knife 413 can be positioned in the most suitable position according to different cutting requirements, thereby improving the cutting accuracy and consistency, adapting to the cutting requirements of facing paper of different sizes and shapes, and improving the versatility and flexibility of the equipment.
[0026] like Figure 3 、 Figure 4As shown, the facing paper fixing component 3 includes a cylinder 301, the top of the cylinder 301 is fixedly connected to the bottom of the fixing plate 208, the output end of the cylinder 301 is fixedly connected to the fixing frame 302, the left inner wall of the fixing frame 302 is fixedly connected to the motor 2 303, the output end of the motor 2 303 is fixedly connected to the rotating rod 304, the end of the rotating rod 304 away from the motor 2 303 is rotatably connected to the right inner wall of the fixing frame 302, the middle part of the outer wall of the rotating rod 304 is fixedly connected to the gear 1 305, the inner front side of the fixing frame 302 is rotatably connected to the double-headed screw 306, the double-headed screw 3 The left and right ends of 06 respectively penetrate the left and right outer walls of the fixed frame 302 and are fixedly connected to the limiting blocks. The middle part of the outer wall of the double-headed screw 306 is fixedly connected with gear 2 307. The rear side of gear 2 307 is meshed with gear 1 305. A sliding rod 2 308 rotatably connected to the fixed frame 302 is provided below the double-headed screw 306. The left and right ends of the sliding rod 2 308 respectively penetrate the left and right outer walls of the fixed frame 302 and are fixedly connected to the limiting blocks. The left and right sides of the outer wall of the double-headed screw 306 are threadedly connected with threaded moving blocks 309 that are slidably connected to the outer wall of the sliding rod 2 308.
[0027] like Figure 3 、 Figure 4 As shown, the bottoms of the left and right threaded moving blocks 309 are fixedly connected to connecting plates 310, the bottoms of the left and right connecting plates 310 are fixedly connected to electric telescopic rods 311, the output ends of the left and right electric telescopic rods 311 are fixedly connected to base plates 312, the four corners of the bottoms of the left and right base plates 312 are rotatably connected to rollers 313, the outer walls of the four rollers 313 are provided with pressure sensors 314, and the four pressure sensors 314 are electrically connected to the electric telescopic rods 311.
[0028] When the facing paper needs to be fixed, motor 2 303 is started, driving the rotating rod 304 to rotate, and then the gear 1 305 fixed on the rotating rod 304 rotates, and the gear 1 305 engages with the gear 2 307, driving the double-headed screw 306 to rotate. When the double-headed screw 306 rotates, the two threaded moving blocks 309 move toward the middle or to the sides at the same time under the guidance of the slide rod 2 308, thereby adjusting the distance between the left and right connecting plates 310 and the roller 313 to adapt to facing papers of different widths.
[0029] After adjusting the distance between the connecting plates 310, the electric telescopic rod 311 extends, pushing the bottom plate 312 downward, so that the roller 313 contacts the facing paper. As the electric telescopic rod 311 continues to extend, the pressure sensor 314 on the roller 313 detects that the pressure reaches the set value, and the electric telescopic rod 311 stops extending. At this time, the roller 313 clamps the facing paper to prevent the paper from moving during the cutting process, thereby ensuring the cutting accuracy. At the same time, the pressure sensor 314 controls the telescopic length of the electric telescopic rod 311, which can provide appropriate pressure according to the thickness of the facing paper, further ensuring the cutting accuracy.
[0030] like Figure 5 As shown, the cutting knife replacement component 4 includes a second fixing plate 401, the top of the second fixing plate 401 is fixedly connected to the bottom of the fixing frame 302, the right side of the second fixing plate 401 is fixedly connected to the motor 3 402, the output end of the motor 3 402 passes through the left side wall of the second fixing plate 401 and is fixedly connected to the rotating rod 403, the left end of the rotating rod 403 is rotatably connected to the screw rod 404, the left end of the screw rod 404 is fixedly connected to the knob 405, the outer wall of the screw rod 404 is threadedly connected to the threaded sleeve 406, the right side of the threaded sleeve 406 is rotatably connected to the rotating ring 407 which is sleeved on the outer surface of the screw rod 404 and does not contact the outer wall of the screw rod 404, the outer wall of the rotating rod 403 is fixedly connected to the fixing sleeve 400, and the outer wall of the fixing sleeve 400 is fixedly connected to the fixing sleeve 400. There are several connecting rods 408 rotatably connected in a circular array, and the ends of several connecting rods 408 away from the fixed sleeve 400 are rotatably connected to the arc plate 410. The outer wall of the rotating ring 407 is rotatably connected to several connecting rods 409 distributed in a circular array, and the ends of several connecting rods 409 away from the rotating ring 407 are rotatably connected to the arc plate 410. The middle part of the connecting rod 408 is rotatably connected to the middle part of the connecting rod 2 409. The side of several arc plates 410 away from the rotating rod 403 is fixedly connected to a connecting block 411, and the side of several connecting blocks 411 away from the arc plate 410 is fixedly connected to two left and right symmetrical limit blocks 412, and a cutting knife 413 is clamped between the left and right limit blocks 412.
[0031] When the cutting blade 413 needs to be replaced, the knob 405 is manually rotated to rotate the screw rod 404. The rotation of the screw rod 404 drives the threaded sleeve 406 to move to the left. The threaded sleeve 406 pushes the rotating ring 407 to move to the left. When the rotating ring 407 moves to the left, the arc plate 410 is pushed inward by the connecting rod 409. Since the middle part of the connecting rod 1 408 is rotatably connected to the middle part of the connecting rod 2 409, and one end of the connecting rod 1 408 is rotatably connected to the fixed sleeve 400, and the other end is rotatably connected to the arc plate 410, the arc plate 410 moves inward under the push of the connecting rod 2 409. Contraction, release the clamping of the cutting knife 413, then remove the old cutting knife 413, replace it with a new cutting knife 413, rotate the knob 405 in the opposite direction, so that the screw rod 404 drives the threaded sleeve 406 to move to the right, and the rotating ring 407 also moves to the right. At this time, the second connecting rod 409 pulls the arc plate 410 to expand outward, clamping the cutting knife 413, completing the replacement of the cutting knife 413, eliminating the need to spend a lot of time on the tedious disassembly and installation process, thereby greatly improving the cutting efficiency of the facing paper, and at the same time, different types of cutting knives 413 can be replaced at any time according to actual needs.
[0032] It should be noted that the pressure sensor 314 is an existing technology and will not be described in detail here. At the same time, the inner wall of the cutting knife 413 is provided with a plurality of snap-in grooves that are adapted to the position and size of the limit block 412, so that the cutting knife 413 will not move relatively when cutting the facing paper.
[0033] The working principle of the facing paper cutting device which is easy to replace the cutting blade is described in detail below.
[0034] like Figure 1-5 As shown, when the cutting knife 413 needs to be adjusted to the left and right positions, the motor 205 is started, driving the rotating shaft 206 to rotate, so that the gear 207 fixed on the rotating shaft 206 rolls on the rack 202. Due to the meshing action of the gear 207 and the rack 202, the front and rear sliding sleeves 204 slide left and right on the slide bar 203, thereby driving the fixed plate 208 and the facing paper fixing assembly 3 and the cutting knife replacement assembly 4 installed thereon to move in the left and right directions, thereby achieving precise adjustment of the cutting position and ensuring accurate cutting of the facing paper. At the same time, the cutting knife 413 can be positioned in the most suitable position according to different cutting requirements, thereby improving the cutting accuracy and consistency, adapting to the cutting requirements of facing paper of different sizes and shapes, and improving the versatility and flexibility of the equipment.
[0035] When the facing paper needs to be fixed, motor 2 303 is started, driving the rotating rod 304 to rotate, and then the gear 1 305 fixed on the rotating rod 304 rotates, and the gear 1 305 engages with the gear 2 307, driving the double-headed screw 306 to rotate. When the double-headed screw 306 rotates, the two threaded moving blocks 309 move toward the middle or to the sides at the same time under the guidance of the slide rod 2 308, thereby adjusting the distance between the left and right connecting plates 310 and the roller 313 to adapt to facing papers of different widths.
[0036] After adjusting the distance between the connecting plates 310, the electric telescopic rod 311 extends, pushing the bottom plate 312 downward, so that the roller 313 contacts the facing paper. As the electric telescopic rod 311 continues to extend, the pressure sensor 314 on the roller 313 detects that the pressure reaches the set value, and the electric telescopic rod 311 stops extending. At this time, the roller 313 clamps the facing paper to prevent the paper from moving during the cutting process, thereby ensuring the cutting accuracy. At the same time, the pressure sensor 314 controls the telescopic length of the electric telescopic rod 311, which can provide appropriate pressure according to the thickness of the facing paper, further ensuring the cutting accuracy.
[0037] When the cutting blade 413 needs to be replaced, the knob 405 is manually rotated to rotate the screw rod 404. The rotation of the screw rod 404 drives the threaded sleeve 406 to move to the left. The threaded sleeve 406 pushes the rotating ring 407 to move to the left. When the rotating ring 407 moves to the left, the arc plate 410 is pushed inward by the connecting rod 409. Since the middle part of the connecting rod 1 408 is rotatably connected to the middle part of the connecting rod 2 409, and one end of the connecting rod 1 408 is rotatably connected to the fixed sleeve 400, and the other end is rotatably connected to the arc plate 410, the arc plate 410 moves inward under the push of the connecting rod 2 409. Contraction, release the clamping of the cutting knife 413, then remove the old cutting knife 413, replace it with a new cutting knife 413, rotate the knob 405 in the opposite direction, so that the screw rod 404 drives the threaded sleeve 406 to move to the right, and the rotating ring 407 also moves to the right. At this time, the second connecting rod 409 pulls the arc plate 410 to expand outward, clamping the cutting knife 413, completing the replacement of the cutting knife 413, eliminating the need to spend a lot of time on the tedious disassembly and installation process, thereby greatly improving the cutting efficiency of the facing paper, and at the same time, different types of cutting knives 413 can be replaced at any time according to actual needs.
[0038] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
