In the present embodiment, since two stations are provided, one finishing mechanism 200 can be used to sequentially process the sheet 500 to be processed at each station.

Conventionally, a worker holds the trimmer to remove the excess edge band 520 from the profiled sheet 510. Because vibration is generated when the edge trimmer runs, hands of workers cannot be ensured to be perpendicular to the edge sealing belt 520 due to the vibration of the edge trimmer, and the inclination of the milling cutter 212 relative to the edge sealing belt 520 can occur, so that the milling cutter 212 damages the special-shaped plate 510, and the plate qualification rate is greatly reduced.

However, in the edge sealing belt trimming device provided by the embodiment of the invention, since the milling cutter assembly 210 is slidingly connected to the translation seat 230 up and down and the translation seat 230 is slidingly connected to the base 100 left and right, the position of the milling cutter 212 in the left-right direction and the up-down direction can be adjusted, so that the milling cutter 212 moves along the J-shaped groove 511 of the special-shaped plate 510 to mill the redundant edge sealing belt 520, and the milling cutter 212 is vertical to the edge sealing belt 520 on the special-shaped plate 510, so that the problem that the milling cutter 212 tilts relative to the edge sealing belt 520 due to vibration generated when the motor 211 operates, and the special-shaped plate 510 is damaged is avoided, and the trimming quality and efficiency are improved.

The edge sealing belt trimming device has the advantages of simple structure, low cost, small labor investment, high trimming quality and efficiency.

As shown in fig. 1 and fig. 3 to fig. 5, a second embodiment of the present invention provides a trimming device for edge banding for a profiled sheet, which is different from the first embodiment in that: the trimming mechanism 200 also includes a first spring 262.

The left side of the translation seat 230 is provided with a first spring 262, the right side of the translation seat 230 is also provided with a first spring 262, and both ends of the first spring 262 are extended in the left-right direction. One end of the first spring 262 is connected to the base 100, and the other end of the first spring 262 is connected to the translation seat 230.

In this embodiment, the first springs 262 are sleeved on the first guide shafts 273, each first guide shaft 273 is provided with two first springs 262, one end of each first spring 262 is abutted against the connecting plate 240, and the other end of each first spring 262 is abutted against the first slider 274.

The first spring 262 positioned at the left side of the translation seat 230 may exert a right-hand elastic force on the translation seat 230, and the first spring 262 positioned at the right side of the translation seat 230 may exert a left-hand elastic force on the translation seat 230. Therefore, the translation seat 230 is subjected to the equal elastic force to force the translation seat 230 and the milling cutter assembly 210 to be in a balanced state when the milling cutter assembly 210 is in a non-working state, so as to prevent the translation seat 230 and the milling cutter assembly 210 from shaking left and right when the milling cutter assembly is in the non-working state.

In this embodiment, due to the two stations and the arrangement of the first spring 262, the milling cutter assembly 210 can be ensured to be located in the middle of the two stations and be in a stable standby state, so that a worker can conveniently place the plate 500 to be processed on the workbench 110 or take away the profiled plate 510 after finishing the milling process, and the situation that the milling cutter assembly 210 moves left and right due to non-human factors and performs wrong processing on the plate 500 to be processed on the stations can be avoided, which results in the plate 500 to be processed as a waste product.

In actual use, when the operator releases the milling cutter assembly 210, the milling cutter assembly 210 is moved to the set position by the first springs 262 on the left and right sides of the translation seat 230, and is in a standby state.

Further, a nut 280 is provided on the left side of the first slider 274, and a nut 280 is also provided on the right side of the first slider 274. The first guide shaft 273 is provided with a screw thread section, and in this embodiment, the screw thread section may be disposed at an end of the first guide shaft 273 near the connection plate 240, and the nut 280 is screwed with the screw thread section of the first guide shaft 273. Each of the first guide shafts 273 is provided with two nuts 280. At this time, one end of the first spring 262 is connected to the first slider 274, and the other end of the first spring 262 is connected to the nut 280, and the connection may be in abutment.

Because the first guide shaft 273 is connected with the nut 280 by screw, the nut 280 can be screwed to adjust the left and right positions of the nut 280 on the first guide shaft 273, so that the elastic force of the first springs 262 on the left and right sides of the first slide block 274 can be respectively adjusted, the milling cutter assembly 210 can be moved to the middle position of the first guide shaft 273 under the action of the two first springs 262, and the milling cutter assembly 210 is prevented from milling the special-shaped plate 510 during non-manual operation.

In addition, the left and right sides of the first slider 274 are provided with shock pads 290. The shock pad 290 may be made of rubber, silicone rubber, or the like. The shock pad 290 has a through hole, so the shock pad 290 is sleeved on the first guide shaft 273; at this time, one end of the first spring 262 near the first slider 274 abuts against the shock pad 290. When the first slider 274 moves excessively to the left or right during manual operation, the provision of the shock pad 290 can exert a cushioning effect, and prevent the first slider 274 from being damaged by strong collision with the connection plate 240 or the nut 280.

Further, the lower side of the milling cutter assembly 210 is provided with a second spring 261. The two ends of the second spring 261 extend in the up-down direction, one end of the second spring 261 is connected with the translation seat 230, and the other end of the second spring 261 is connected with the milling cutter assembly 210.

In this embodiment, the second springs 261 are sleeved on the second guide shafts 271, each second guide shaft 271 is provided with a second spring 261, the upper end of the second spring 261 abuts against the second slider 272, and the lower end of the second spring 261 abuts against the translation seat 230.

Further, the upper and lower sides of the second slider 272 are provided with shock pads 290. The damper 290 is sleeved on the second guide shaft 271. When the second slider 272 moves up or down excessively, the shock pad 290 can provide a buffering effect to prevent the second slider 272 from being damaged due to collision with the translation seat 230.

In addition, a shock pad 290 may be provided at the lower side of the second spring 261, and the shock pad 290 is also coupled to the second guide shaft 271.

As shown in fig. 2, a third embodiment of the present invention provides a bead dressing apparatus for a profiled sheet, which is different from the first embodiment in that the bead dressing apparatus further includes a scrap collecting bin 600.

The shape of the waste collection bin 600 is not limited. The waste collection bin 600 is located below the milling cutter 212, and the waste collection bin 600 is provided with a collection port 610, with the opening of the collection port 610 facing upward. Specifically, the waste collection bin 600 is hollow to form a collection chamber that can collect the removed edge strip 520. The upper end of the collection chamber has an open structure, specifically a collection port 610, and the scraps milled by the milling cutter 212 directly fall down to the scrap collection bin 600. When the edge banding trimming apparatus is in a non-operating state, the waste collection tank 600 may be taken out and the waste in the waste collection tank 600 may be dumped.

Further, the waste collection tank 600 may be connected to the base 100 by bolts, so that the waste collection tank 600 is fastened to the base 100. The waste collection tank 600 is provided with a discharge port communicating with the collection chamber, and in this embodiment, the discharge port is located at the rear side of the waste collection tank 600, with the opening of the discharge port being disposed rearward. The waste collection bin 600 is L-shaped.

The waste collection bin 600 is also provided with a sealing plate 620, the sealing plate 620 covering the discharge opening to prevent waste from falling out of the discharge opening. The closing plate 620 is detachably connected to the waste collection tank 600 so that the closing plate 620 is detached to take out the waste collected by the waste collection tank 600 from the discharge port. In this embodiment, the closing plate 620 is connected to the scrap collecting receptacle 600 by bolts. Of course, the closing plate 620 may also be connected to the waste collection bin 600 by a snap-fit arrangement.

In some embodiments, since the trimming of the edge banding strip 520 by the tool bit 214 will generate the scraps of the edge banding strip 520, most of the scraps will fall directly into the scrap collecting bin 600, but part of the scraps will remain in the J-shaped groove 511 of the shaped sheet 510, and of course, scraps will also be generated during chamfering operation of the shaped sheet 510, and therefore, the edge banding trimming device further includes a scrap removing mechanism.

The chip removing mechanism may be an air gun. After finishing the edge sealing strip 520 of the profiled sheet 510, a worker may use an air gun to remove the remaining debris from the profiled sheet 510.

Further, an air gun may be provided on the base 100, for example, on the rear side of the table top 110, capable of outputting high-pressure air toward the J-shaped groove 511 of the profiled sheet 510, moving along the J-shaped groove 511, and blowing the scraps located in the J-shaped groove 511 toward the scrap collecting receptacle 600.

In other embodiments, the guide plate 420 is provided with a plurality of air holes near the surface of the J-shaped groove 511, the air holes may be arranged at intervals along the front-rear direction of the guide plate 420, the guide plate 420 is internally provided with an air passage, the air passage is communicated with the air holes, the air holes are obliquely arranged, and the air passage is communicated with air supply equipment such as a high-pressure air tank, an air compressor and the like. When trimming the edge sealing strip 520 on the profiled sheet 510, high-pressure gas can be blown out from the air holes and the scraps on the J-shaped groove 511 are removed, so that the trimming work and the scraps removing work of the edge sealing strip 520 are simultaneously carried out, and the overall working efficiency is improved.

In other embodiments, the tool bit 214 is disposed on the spindle, and the tool bit 214 may be integrally formed with the spindle or may be detachably connected. In addition, the main shaft sleeve is provided with miniature bearings, and the number of the miniature bearings can be one, two or more. The guide 213 is cylindrical and made of a metal material such as stainless steel. The outer peripheral surface of the guide 213 is smooth. The front end surface of the guide part 213 is concavely provided with a first cylindrical groove with a forward opening, and the first cylindrical groove can be sleeved on the miniature bearing, namely, the inner ring of the miniature bearing is fixedly connected with the main shaft, and can rotate along with the rotation of the main shaft; the outer ring of the micro bearing is fixedly connected with the inner circumferential surface of the first cylindrical groove, and can rotate along with the rotation of the guide part 213.

A certain distance exists between the front end of the guide portion 213 and the rear end of the cutter head 214. The rear end surface of the guide portion 213 is concavely formed with a second cylindrical groove having an opening rearward, the second cylindrical groove having an inner diameter larger than that of the first cylindrical groove, and the second cylindrical groove being provided with an internal thread. The guide portion 213 is provided with a plurality of air outlet holes, each of which is a circular hole, and extends backward from the front end surface of the guide portion 213, and the axes of the air outlet holes extend forward and backward, and the air outlet holes are circumferentially arranged with the center axis of the guide portion 213 as the center of a circle. All the air outlet holes are communicated with the second cylindrical groove. The guide part 213 is connected with a straight-through rotary joint, and the straight-through rotary joint can be a joint with the model number of KSH 04-M5. The outer diameter of the guide 213 is slightly larger than the diameter of the through-going swivel. The straight-through rotary joint is provided with an air inlet and an air outlet, the straight-through rotary joint is connected with the inner threads of the second cylindrical groove, the air outlet is promoted to be communicated with the second cylindrical groove, and the air outlet is connected to the air supply pipe.

At this time, the guide 213, the through rotary joint and the air supply pipe together form a set of chip removing mechanism. The air supply pipe may be connected to a high pressure air tank or an air compressor.

Further, the front end of the air outlet hole is in a horn shape.

When the gas supply pipe outputs high-pressure gas, the high-pressure gas is sprayed out through the straight rotary joint, the second cylindrical groove and all the gas outlet holes in sequence. When the operator drives the motor 211 to move in the up-down direction and the left-right direction, the guide 213 slowly rolls along the J-shaped groove 511, and the rotation speed of the guide 213 is not consistent with the rotation speed of the cutter head 214. At this point, the tool bit 214 can chamfer the profiled sheet 510 and trim the edge strip 520. The high-pressure air is ejected from the air outlet hole toward the front of the guide 213, and the scraps remaining in the J-shaped groove 511 can be removed, and the scraps can be blown to the scrap collecting box 600.

Since the guide part 213 can move along the J-shaped groove 511 along with the cutter head 214, and all the air outlet holes are circumferentially arranged on the front end surface of the guide part 213, the high-pressure air sprayed from the air outlet holes of the guide part 213 can well blow off the scraps generated during the operation of the cutter head 214 in the moving process of the guide part 213 and the cutter head 214, so as to ensure the clean wall surface of the J-shaped groove 511.

So design, not only can accomplish the sweeps and clear away at tool bit 214 during operation, moreover, overall structure is compact, and is with low costs, when tool bit 214 switches the use at two stations, and guide 213 homoenergetic provides high-pressure gas, carries out the sweeps clearance to J-shaped groove 511 on two stations respectively, need not to set up one set of sweeps removal mechanism to every station.

The axis of the air outlet hole extends forward and backward, so that part of the high-pressure air moves along the surface of the J-shaped groove 511, which is in contact with the guide part 213, after being sprayed, and the waste scraps remained on the surface of the J-shaped groove 511 can be cleaned well. In addition, since the guide 213 rolls along the J-shaped groove 511 during operation of the edge band trimming device, high-pressure air discharged from all the air outlet holes of the guide 213 flows in a spiral shape, and the cleaning effect of the scraps on the J-shaped groove 511 can be improved.

It will be appreciated that the gas supply pipe may be provided between two guide plates 420, with a certain distance between the guide portion 213 and the front end of the guide plate 420, so as to avoid the guide plate 420 from affecting the left-right movement of the guide portion 213. The gas supply pipe may be a plastic hose. A baffle is arranged on the mounting seat 250 and is positioned between the motor 211 and the milling cutter 212, so as to prevent waste scraps from being blown onto the motor 211 under the action of high-pressure gas.

The fourth embodiment of the invention provides a trimming device for edge banding for special-shaped plates, which is different from the first embodiment in that: the edge banding band trimming apparatus further includes a Y-axis servo and a Z-axis servo.

The Y-axis servo mechanism is disposed on the base 100, and an output end of the Y-axis servo mechanism is connected to the translation seat 230, so that the translation seat 230 can be driven to move in a left-right direction, and a left-right position of the milling cutter 212 can be accurately controlled. The Y-axis servo mechanism may be an existing linear module, preferably, a ball screw type linear module, where the motor of the linear module is a servo motor, and the translation seat 230 is connected and fixed with a sliding table of the linear module, and when the motor operates, the translation seat 230 can move left and right along with the sliding table.

The Z-axis servo mechanism is disposed on the translation seat 230, and an output end of the Z-axis servo mechanism is connected to the milling cutter assembly 210, so that the milling cutter assembly 210 can be driven to move in an up-down direction, and the up-down position of the milling cutter 212 can be precisely controlled. Similarly, the Z-axis servo is an existing linear module, the milling cutter assembly 210 is fixedly connected with the sliding table of the linear module, and the milling cutter assembly 210 can move up and down along with the sliding table when the Z-axis servo operates.

It will be appreciated that the motors 211 of the Y-axis servo, Z-axis servo and milling cutter assembly 210 are all electrically connected to a control system that is capable of controlling the start and shut down of the same.

After the plate 500 to be processed is accurately fixed on the table top 110, the milling cutter assembly 210 starts to operate under the control of the control system, and the milling cutter 212 is in a high-speed rotating state; then, the Y-axis servo mechanism and the Z-axis servo mechanism operate under the control action of the control system; since the positioning work of the sheet 500 to be processed is completed and the dimensions of the J-shaped groove 511 of the shaped sheet 510 are known at the time of manufacturing the shaped sheet 510, the control system can control the movement trace of the milling cutter 212 according to the dimension data of the J-shaped groove 511, so that the milling cutter 212 performs milling treatment on the edge sealing belt 520 positioned at the J-shaped groove 511.
