[0061] A ring-shaped support surface is formed on the rotary feeding device 400. The sponge waiting to be cut part 500 is placed on the support surface and moves to the cutting area position as the rotary feeding device 400 rotates.
[0062] The main frame 100 of the gantry is shaped like a gate and includes main vertical beams 110 and main horizontal beams 120. The main vertical beams 110 are spaced apart and the main horizontal beams 120 are located between the two main vertical beams 110.
[0063] The inner side of the annular support surface closer to the rotation center is defined as the inner side, and the outer side away from the rotation center is defined as the outer side. The two main uprights 110 are respectively set on the inner and outer sides of the support surface. In other words, the gantry main frame 100 spans the inner and outer sides of the support surface.
[0064] Combination Figure 5 A connector 140 is provided on the main upright beam 110. The connector 140 is movably connected to the gantry main frame 100 along the height direction of the main upright beam 110.
[0065] The gantry work frame 200 is connected to the connector 140. Under the action of the connector 140, the gantry work frame 200 can be raised and lowered along the gantry main frame 100, thereby driving the cutter assembly 600 to move so as to cut the workpiece 500 along the height direction of the workpiece 500.
[0066] A cutting area is formed on the gantry work frame 200, and the workpiece 500 to be cut moves to the cutting area position with the rotary feeding device 400.

[0068] The gantry work frame 200 is rotatable in the vertical direction relative to the gantry main frame 100 to adjust the cutting angle of the blade belt 610 passing through the work area. The angle of the gantry work frame 200 relative to the gantry main frame 100 is adjusted according to the different cutting thicknesses of the workpiece to be cut, thereby improving the cutting quality of the cutting surface.
[0069] The following is a detailed description of each component of the disc flat cutter:
[0070] refer to Figure 5 , Figure 6 A first screw 130 is vertically installed on the gantry main frame 100. The outer wall of the first screw 130 is formed with an external thread. A first moving part 131 and a second moving part 132 are spaced apart on the first screw 130. Threaded holes are formed in the first moving part 131 and the second moving part 132. The first moving part 131 and the second moving part 132 are threadedly connected to the first screw 130.
[0071] The connector 140 is disposed between the first moving part 131 and the second moving part 132. Specifically, the connector 140 includes a timing sleeve 142 sleeved on the outside of the first screw 130 and a connecting plate 141 fixed to the timing sleeve 142. The timing sleeve 142 is sleeved on the first screw 130, and the gantry frame 200 is connected to the connecting plate 141.
[0072] The first screw 130 is connected to the first drive assembly, which is connected to the gantry main frame 100. The first drive assembly is used to drive the first screw 130 to rotate, so that the first moving part 131 and the second moving part 132 drive the connecting member 140 to rise and fall.
[0073] In some embodiments of this application, a first screw 130 is respectively provided on the inner side of the main upright beam 110. The first screw 130 is driven by a first drive assembly. The first drive assembly switches synchronously, causing the two first screws 130 to rotate synchronously, thereby realizing the lifting and lowering of the gantry work frame 200.
[0074] In some other embodiments, the first drive assembly includes a first drive member 160, a first drive shaft 161 connected to the output end of the first drive member 160, and a first adapter 170 connected to the first drive shaft 161; the first drive shaft 161 is perpendicularly connected to each of the first screws 130 through the first adapter 170.
[0075] The first adapter 170 includes an adapter seat, a worm gear, and a worm. The worm gear and the worm are connected to each other and are rotatably connected to the adapter seat. The first drive shaft 161 is connected to the worm gear, and the worm is connected to the first screw 130 or the worm is an extension of the first screw 130, so as to realize the power transmission between the first screw 130 and the first drive shaft 161.
[0076] The first driving component 160 is mounted on the main crossbeam 120, and multiple bearing seats are spaced apart on the main crossbeam 120. The first transmission shaft 161 is rotatably connected to the bearing seats to drive the synchronous rotation of the two first screws 130.
[0077] In some other embodiments, the inner side of the main beam 110 is also provided with a first guide rail 150 extending along the height direction of the main beam 110, and the connecting member 140 is provided with a limiting part on the side near the main beam 110. A first guide groove 143 is formed on the limiting part, and the first guide groove 143 is movably connected to the first guide rail 150.
[0078] Driven by the first screw 130, the connecting piece 140 moves up and down along the first guide rail 150, which helps to improve the stability of the gantry frame 200 during the up and down movement and reduce the shaking of the gantry frame 200 during the movement.
[0079] To improve the overall stability of the gantry main frame 100, a support base is also provided at the bottom of the gantry main frame 100. The bottom of the main upright beam 110 is fixed on the support base. The support base has a large overall mass, which makes the gantry main frame 100 stable and avoids problems such as tilting or even falling over.
[0080] 200 gantry work scaffold
[0081] refer to Figures 7-9 The gantry work frame 200 includes a working crossbeam 220 and a working upright 210. There are two working uprights 210, which are respectively arranged on both sides of the working crossbeam 220 to make the gantry work frame 200 as a whole a gantry structure.
[0082] A second drive member 240 and a second transmission shaft 230 connected to the output end of the second drive member 240 are provided between the gantry work frame 200 and the gantry main frame 100. The second transmission shaft 230 is connected to the gantry work frame 200 and is used to adjust the cutting angle of the blade belt 610 passing through the cutting area.
[0083] In some embodiments, the second drive member 240 is disposed on the gantry main frame 100, and the output end of the second drive member 240 is connected to the second transmission shaft 230. The second transmission shaft 230 is fixed to the gantry work frame 200. When the second drive member 240 is started, it drives the second transmission shaft 230 to rotate, thereby driving the gantry work frame 200 to rotate at an angle relative to the gantry main frame 100.
[0084] In other embodiments, the second drive shaft 230 is rotatably connected to the side of the gantry frame 200 connected to the gantry main frame 100 via a bearing seat. The second drive member 240 is also fixed on the gantry frame 200. The second drive member 240 and the second drive shaft 230 are connected by a synchronous belt. Specifically, the synchronous belt is a rack and pinion, and a synchronous gear is provided on the second drive shaft 230. The synchronous belt is connected to the synchronous gear to realize the drive of the second drive member 240 on the second drive shaft 230.
[0085] The connector 140 includes a synchronizing sleeve 142 and a connecting plate 141 hinged to the synchronizing sleeve 142. The synchronizing sleeve 142 is sleeved on the outside of the first screw 130, and the connecting plate 141 is arranged along the axial direction of the first screw 130.
[0086] The two ends of the second drive shaft 230 are respectively connected to a second screw 260 through the second adapter 250. The second screw 260 is perpendicular to the second drive shaft 230, and the end of the second screw 260 is connected to the gantry main frame 100.
[0087] The second adapter 250 includes an adapter seat and a worm gear. The adapter seat is fixed on the working crossbeam 220, the worm gear is connected to the second transmission shaft 230, and the end of the second screw 260 extends outside the adapter seat and is hinged to the upper side of the connecting plate 141.
[0088] An inclined support 144 extending toward the gantry frame 200 is also formed on the lower side of the connecting plate 141. A connecting groove is formed on the side wall of the gantry frame, and the inclined support 144 is hinged in the connecting groove.
[0089] That is, the second screw 260 and the inclined bracket 144 are located on the upper and lower sides of the hinge position between the connecting plate 141 and the synchronous sleeve 142, respectively.
[0090] The tilting bracket is located below the second screw 260. When the second screw 260 extends or retracts, the connecting plate 141 rotates at an angle relative to the synchronous sleeve 142, so that the gantry work frame 200 tilts at an angle.
[0091] Specifically, when it is necessary to adjust the bottom of the gantry frame 200 to tilt outward, the second drive member 240 drives the second transmission shaft 230 to rotate, which in turn drives the second screw 260 to extend relative to the gantry frame 200. The extension of the second screw 260 drives the tilting bracket 144 to move outward, pushing the bottom of the gantry frame 200 away from the gantry main frame 100, thus increasing the tilt angle of the gantry frame 200.
[0092] The second driving component 240 drives the second transmission shaft 230 to rotate in the opposite direction, the second screw 260 shortens relative to the gantry frame 200, the connecting plate 141 rotates at an angle relative to the synchronous sleeve 142, the tilting bracket 144 returns to center, and the gantry frame 200 returns to its original position under its own gravity.
[0093] During the above process, the end of the tilting bracket 144 is always located in the connecting groove, which improves the stability of the gantry work frame 200 during the tilting process.
[0094] Cutter assembly 600
[0095] refer to Figure 10 The cutter assembly 600 is mounted on the gantry work frame 200. The cutter assembly 600 includes a blade belt 610, part of which passes through the cutting area and is used to cut the workpiece 500 that has passed through the cutting area.
[0096] The cutter assembly 600 also includes a drive wheel assembly, which includes a drive wheel assembly 620 and a driven wheel assembly 630 connected to the gantry frame 200. The drive wheel assembly 620 is connected to the drive motor, and the blade belt 610 is wrapped around the outside of the drive wheel assembly.
[0097] The drive wheel assembly 620 and the driven wheel assembly 630 are rotatably connected to the gantry frame 200 via bearings, and the drive wheel assembly 620 is connected to the drive motor.
[0098] There are three driven wheel assemblies 630, one of which is a drive wheel assembly 620 located at one end of the cutting zone and the other driven wheel assembly 630 located at the other end of the cutting zone, providing cutting force to the portion of the blade belt 610 passing through the cutting zone.
[0099] The other two driven wheel assemblies 630 are respectively positioned above the driving wheel assembly 620 and the driven wheel assembly 630 located at the other end of the cutting zone.
[0100] For example, but not limited to, the driving wheel assembly 620 and one of the driven wheel assemblies 630 are respectively mounted at the bottom of the two working beams, and the other two driven wheel assemblies 630 are mounted on the working crossbeam or above the working beam.
[0101] A sharpening device 640 is also installed on the working gantry frame. The blade belt 610 is sharpened by the sharpening device 640.
[0102] 300 pressure roller assembly
[0103] refer to Figure 11 , Figure 12 The pressure roller assembly 300 includes two vertically arranged support beams 310 and a pressure roller 330 connected between the two support beams 310. The two support beams 310 are spaced apart and parallel to each other.
[0104] The support beam 310 is connected to the inside of the gantry frame 200, and the pressure roller 330 is configured to move up and down along the height direction of the support beam 310.
[0105] Specifically, in some embodiments, a third driving member 320 and a third screw 322 are provided on the top of the support beam 310. The third screw 322 is parallel to the support beam 310 and rotatably connected to the support beam 310. The two ends of the pressure roller 330 are rotatably connected to the third screw 322 respectively. The third driving member 320 drives the pressure roller 330 to rise and fall relative to the support beam 310 through the third screw 322.
[0106] There can be two third driving components 320, each connected to a corresponding third screw 322, and the two third driving components 320 drive the corresponding third screw 322 respectively.
[0107] In some other embodiments, there is one third drive member 320, which is fixed on one of the support beams 310. Two third screws 322 are connected by a third drive shaft 321, which is connected to the output end of the third drive member 320. Each third screw 322 is connected to the third drive shaft 321 by a third adapter 350. The third drive member 320 drives the two third screws 322 to rotate synchronously through the third drive shaft 321.
[0108] The third adapter 350 includes an adapter seat, a worm gear, and a worm. The worm gear and the worm are connected to each other and are rotatably connected to the adapter seat. The worm gear is fixed to the third drive shaft 321, and the worm is coaxially connected to the third screw 322, or the worm is an extension of the third screw 322.
[0109] The third driving component 320 drives the third transmission shaft 321 to rotate, which in turn drives the worm gear to rotate. After the worm gear transmission, the power is output to the third screw 322, which in turn drives the third screw 322 to rotate.
[0110] The two ends of the pressure roller 330 are connected to the third screw 322 through the lifting block 340. The lifting block 340 has a threaded hole, which is connected to the third screw 322. During the rotation of the third screw 322, the lifting block 340 moves up and down along the third screw 322.
[0111] The support beam 310 is also provided with a second guide rail 311 extending along the height direction of the support beam 310, and the lifting block 340 is formed with a second guide groove 341, which is connected to the second guide rail 311.
[0112] The second guide rail component 311 helps to improve the stability of the pressure roller 330 during the lifting process.
[0113] The pressure roller 330 is conical, and the lower tangent of the conical pressure roller 330 is parallel to the support surface.
[0114] The first end of the pressure roller 330 is located inside the turntable 410, and the second end of the pressure roller 330 is located outside the turntable 410. The outer diameter of the first end of the pressure roller 330 is smaller than that of the second end.
[0115] In other words, the outer diameter of the pressure roller 330 gradually increases along the direction away from the center of the support surface of the ring.
[0116] The linear velocity of the first end of the pressure roller 330 is equal to the linear velocity of the inner side of the turntable 410, and the linear velocity of the second end of the pressure roller 330 is equal to the linear velocity of the outer side of the turntable 410, so as to limit the top of the workpiece 500 to be cut and prevent the workpiece 500 to be cut from being misaligned during the cutting process.
[0117] The first end of the pressure roller 330 is located inside the turntable 410, and the second end of the pressure roller 330 is located outside the turntable 410. The outer diameter of the first end of the pressure roller 330 is smaller than that of the second end.
[0118] A fourth driving component 331 is also provided on the support beam 310. The fourth driving component 331 is connected to the pressure roller 330 and is used to drive the pressure roller 330 to rotate.
[0119] Specifically, the second end of the pressure roller 330 is provided with an extension, and the output end of the fourth drive member 331 is connected to the extension via a synchronous belt.
[0120] A bearing is provided between the pressure roller 330 and the lifting block 340 to ensure that the pressure roller 330 rotates smoothly.
[0121] Rotary feeder 400
[0122] refer to Figures 13-18The rotary feeding device 400 includes a rotary drive, a turntable 410, and a rolling support 440. The turntable 410 is annular, and the support surface is formed on the turntable 410.
[0123] The rotary drive component is connected to the turntable component 410 and is used to drive the turntable component 410 to rotate.
[0124] Rolling support members 440 are spaced apart at the bottom of turntable member 410 to provide support for turntable member 410.
[0125] Specifically, the turntable component 410 includes a turntable frame 411 and a plurality of fan-shaped support units 412 disposed on the turntable frame 411. The support units 412 are fixed on the turntable frame 411, and some of the support units 412 have suction holes 413 formed on them. The suction holes 413 are connected to the suction device.
[0126] The workpiece 500 to be cut is placed on the support unit 412 with suction holes 413. When the support unit 412 without suction holes 413 passes through the cutting area, the gantry work frame 200 descends a target distance relative to the gantry main frame 100 to cut the workpiece 500 to be cut on the downstream support unit 412 that has been transported to the cutting area.
[0127] For details, please refer to the following: Figure 14 The inner side of the turntable frame 411 is detachably connected to a rotary support 430, and the transmission gear 431 is formed on the inner side of the rotary support 430.
[0128] The slewing support 430 is fixed to the turntable frame 411 by fasteners.
[0129] refer to Figure 15 , Figure 16 The rotary drive component is specifically an electromagnetic drive component 420, which is mounted on the drive base 421. The output end of the electromagnetic drive component 420 extends in the vertical direction. The drive gear 422 is horizontally rotatably connected to the drive base 421 and is engaged with the transmission gear 431 on the rotary support component 430.
[0130] Compared to mechanical drives, the electromagnetic drive unit 420 has advantages such as high power, compact structure, and high reliability. It also offers high instantaneity of switching, small installation space, and higher precision in switch control.
[0131] Driven by the electromagnetic drive unit 420, the drive gear 422 rotates horizontally, thereby driving the turntable unit 410 to rotate.
[0132] The rolling support 440 is arranged at intervals along the periphery of the turntable 410 below the outer edge of the turntable 410, and specifically includes a support base 441 and a roller 446 rotatably connected to the support base 441.
[0133] refer to Figure 17 , Figure 18 In some other embodiments, the height of the roller 446 is adjustable to adjust the height of the turntable 410. Correspondingly, the rotation drive also rises and falls with the turntable 410. This can be achieved by adding or removing pads at the bottom of the drive base 421. Of course, the drive base 421 can also be made to be height-adjustable.
[0134] The roller 446 is connected to the support base 441 via the lifting bracket 445. The support base 441 has outwardly extending support protrusions 442 on both sides. Threaded holes are formed on the support protrusions 442. The bottom of the lifting bracket 445 is connected to an adjusting screw 444 that mates with the threaded holes.
[0135] The lifting bracket 445 is connected to two adjusting screws 444 through the middle connecting part 443. By adjusting the adjusting screws 444 on both sides, the lifting bracket 445 can be driven to rise and fall.
[0136] The adjusting screw 444 is in contact with the bottom of the lifting bracket 445. Specifically, a support hole is provided at the bottom of the lifting bracket 445. The support hole is a blind hole structure. The end of the adjusting screw 444 extends from bottom to top through the threaded hole on the support protrusion 442 and into the support hole to support the lifting bracket 445. Rotating the adjusting screw 444 can change the length of the adjusting screw 444 extending upward from the support protrusion 442, thereby adjusting the height of the lifting bracket 445. This makes it more versatile and adaptable, meeting different cutting needs.
[0137] The rolling support 440 is also provided with a limit stop 447 on the side opposite to the turntable 410, and the height of the limit stop 447 is higher than that of the turntable 410.
[0138] The limiting barrier 447 is arranged along the circumference of the turntable 410 on the outside of the turntable 410, which plays a limiting role in the rotation of the turntable 410, preventing the turntable from being displaced, ensuring the cooperation between the turntable and the electromagnetic drive component, and improving the working stability.
[0139] The working process of this disc flat cutter will be described in detail below:
[0140] The gantry main frame 100 and the gantry work frame 200 are arranged along the radial direction of the turntable component 410, spanning the inner and outer sides of the turntable component 410.
[0141] The gantry work frame 200 can be tilted relative to the gantry main frame 100. A free tilt sensor is also installed on the gantry main frame 100. The tilt angle of the gantry is monitored in real time by the tilt sensor. The tilt angle of the gantry is transmitted to the display screen by the tilt sensor, which makes it convenient for the operator to observe and control.
[0142] Driven by the rotary drive, the turntable 410 rotates one revolution, and the gantry work frame 200 descends relative to the gantry main frame 100 by the thickness of a piece of material to be cut 500.
[0143] Based on the thickness of the target sponge sheet, the cutting angle of the blade relative to the workpiece 500 is adjusted by adjusting the tilt angle of the gantry work frame 200 relative to the gantry main frame 100, thereby improving the cutting quality of the cutting surface.
[0144] For example, practice has shown that when the target thickness of the sponge sheet to be cut increases, the tilt angle of the blade relative to the workpiece to be cut also increases, and correspondingly, the included angle between the gantry work frame and the gantry main frame decreases.
[0145] Conversely, when the target thickness of the sponge sheet to be cut decreases, the tilt angle of the blade relative to the workpiece to be cut also decreases, and correspondingly, the angle between the gantry work frame and the gantry main frame increases.
[0146] The tilt angle of the gantry monitored by the tilt sensor can be substituted into the formula to calculate the height of the pressure roller 330 relative to the turntable 410 and the adjustment height of the pressure roller 330 after each cut.
[0147] For example, combining Figure 4 When the inclination angle between the gantry work frame 200 and the gantry main frame 100 is α, and the cutting adjustment height of the gantry work frame 200 each time is h, then after each cutting, the moving distance of the pressure roller 330 relative to the gantry work frame 200 is L, which satisfies: L=h / cosα.
[0148] The sponge waiting to be cut 500 is placed on the support unit 412 of the turntable 410 with suction holes 413. The suction holes 413 provide suction to the waiting to be cut 500, so that the waiting to be cut 500 is fixed on the support unit 412 and rotates with the turntable 410. There can be multiple waiting to be cut 500.
[0149] As the turntable 410 rotates, the workpiece 500 to be cut passes through the cutting area and is cut into thin slices by the running blade 610. The suction hole 413 can ensure that the workpiece 500 to be cut does not shift when it is cut by the blade 610.
[0150] Initially, the support unit 412 without the suction hole 413 is located below the cutting area. Adjust the height of the gantry work frame 200 to move the blade belt 610 to the appropriate height position.
[0151] The pressure roller 330 is used to limit the cut material. The linear velocity of each position of the pressure roller 330 is the same as that of the turntable 410 at the corresponding position, so as to limit the cut sheet.
[0152] The linear velocities at both ends of the pressure roller 330 are equal to the linear velocities on the inner and outer sides of the corresponding turntable 410, so as to achieve stable and accurate positioning of the workpiece 500 to be cut, avoid displacement of the upper material after cutting, and improve cutting quality and cutting accuracy.
[0153] The height of the pressure roller 330 is adjusted according to the thickness of the cut sheet. That is, as the height of the gantry frame 200 continues to move down, the pressure roller 330 installed on the gantry frame 200 rises to the target height to ensure that the height of the pressure roller 330 is always pressing on the top of the material to be cut.
[0154] The height adjustment of the gantry work frame 200 and the pressure roller 330 is completed when the cutting area passes through the support unit 412 without the suction hole 413. When the height adjustment is not completed, the rotary drive is turned off until the height adjustment of the gantry work frame 200 and the pressure roller 330 is completed, and then it is restarted.
[0155] A first sensing element is provided on the gantry main frame 100. The first sensing element is used to sense the lowest position of the gantry work frame 200. When the gantry work frame 200 moves down to the position of the first sensing element, the first driving element 160 drives the first screw 130 to rotate, so that the gantry work frame 200 moves up and resets.
[0156] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
