Description

[0002] Foam is a lightweight, porous plastic material with excellent cushioning, thermal insulation, sound insulation, sound absorption and other properties. Polyurethane foam is one of the foams, which is formed by the polycondensation and foaming of isocyanate and polyol. It has the characteristics of softness, comfort, good elasticity, wear resistance and chemical corrosion resistance.

[0003] The foaming method of polyurethane foam is divided into free foaming and model foaming. The free foaming is to inject the mixed raw materials directly into an open space or mold, and let it expand freely.

[0042] As shown in Figure 1 and Figure 4 The cutting mechanism 2 includes a first groove-shaped electric sliding seat 25 connected to the processing base 1 along the left and right direction, the two vertical segments of the first groove-shaped electric sliding seat 25 are fixedly connected with the displacement track 21 between the opposite faces, the horizontal segment of the first groove-shaped electric sliding seat 25 penetrates the base 1, the displacement track 21 is slidably connected with the electric sliding sleeve 22 along the front and rear direction, the left side of the electric sliding sleeve 22 is limitingly and slidably connected with the vibration knife cutting machine 23 along the up and down direction (the vibration knife cutting machine is prior art), the left side of the electric sliding sleeve 22 is rotatably connected with the screw rod 24 arranged along the up and down direction, the screw rod 24 is threadedly connected with the vibration knife cutting machine 23, the upper surface of the electric sliding sleeve 22 is fixedly installed with the first driving motor, the output shaft of the first driving motor is fixedly connected with the top end of the screw rod 24.

[0043] In specific use, first, the foam substrate to be cut is placed on the upper surface of the processing base 1, then the first groove-shaped electric sliding seat 25 is moved on the processing base 1 along the left and right direction, the electric sliding sleeve 22 is moved on the displacement track 21 along the front and rear direction, the vibration knife cutting machine 23 is moved to the starting cutting position, then the first driving motor drives the screw rod 24 to rotate, so that the screw rod 24 drives the vibration knife cutting machine 23 to move downward, the electric sliding sleeve 22 drives the vibration knife cutting machine 23 to move along the front and rear and left and right directions, and the circular cutting on the foam substrate is started.

[0044] It should be noted that the starting cutting position is located at the left rear of the base 1.

[0045] As shown in Figure 1 and Figure 5 The clamping mechanism 3 includes a second groove-shaped electric sliding seat 35 connected to the processing base 1 along the left and right direction, the upper surfaces of the two vertical segments of the second groove-shaped electric sliding seat 35 are commonly provided with an auxiliary part 34, the right side of the auxiliary part 34 is provided with a linkage part 31 linked with the cutting mechanism 2, the lower side of the linkage part 31 is provided with a clamping part 32, and the lower side of the linkage part 31 is provided with an adjusting part 33 for adjusting the clamping size of the clamping part 32.

[0046] In specific use, before the vibrating knife cutting machine 23 starts to cut the foam base material, the clamping size of the clamping member 32 is first adjusted by the adjusting member 33 according to the size of the ring to be cut, and when the vibrating knife cutting machine 23 starts to cut by moving downward, the adjusting member 33 and the clamping member 32 are simultaneously moved downward by the linkage member 31 at this time, and the clamping member 32 is located outside the range of the foam base material, that is, the clamping member 32 does not clamp the ring.

[0047] When the vibrating knife cutting machine 23 completes a ring cutting, the vibrating knife cutting machine 23 moves to the next cutting position, and at this time the vibrating knife cutting machine 23 drives the clamping member 32 to move to the upper position of the first cutting position of the vibrating knife cutting machine 23, and since the completion of a ring cutting requires two cutting strokes of the vibrating knife cutting machine 23, that is, the vibrating knife cutting machine 23 needs to move in the up-down direction twice, when the vibrating knife cutting machine 23 moves in the up-down direction for the first time, the vibrating knife cutting machine 23 drives the clamping member 32 to move downward to clamp the ring at the first cutting position by the clamping member 32, and when the vibrating knife cutting machine 23 completes a cutting stroke, the vibrating knife cutting machine 23 moves upward to simultaneously drive the clamping member 32 to move upward, thereby separating the ring cut by the previous cutting from the foam base material, and then the ring clamped on the clamping member 32 is taken off from the clamping member 32 by the conveying mechanism 4 and conveyed to the next process, and then the vibrating knife cutting machine 23 moves downward again to perform a second cutting stroke, and the vibrating knife cutting machine 23 drives the clamping member 32 to move downward again, and at this time the clamping member 32 performs an empty clamping stroke.

[0048] When the vibrating knife cutting machine 23 completes a row of ring cutting in the front-back direction on the foam base material, the vibrating knife cutting machine 23 needs to continue to move forward and move in the up-down direction to drive the clamping member 32 to take off the frontmost ring in the row from the foam base material, and then the vibrating knife cutting machine 23 moves to the last end on the displacement track 21 and moves to the right by the first recess-shaped electric sliding seat 25 to perform the cutting work of the next row, and so on to cut a plurality of rows of ring products from the sheet-shaped polyurethane material foam base material.

[0049] As shown in Figure 5 The auxiliary member 34 includes first sliding frames 342 fixedly connected to the upper surface of the vertical section of the second recess-shaped electric sliding seat 35, and a second sliding frame 343 is slidably connected to the two first sliding frames 342 in the up-down direction, and an electric sliding block 341 is slidably connected to the second sliding frame 343 in the front-back direction.

[0050] As shown in Figure 5 and Figure 6As shown, the linkage 31 comprises a fixed seat 314 fixedly connected to the right side surface of the electric sliding block 341, the upper surface of the fixed seat 314 is rotationally connected with a rotating disc 313, the upper surface of the rotating disc 313 is fixedly connected with a connecting sliding sleeve 311, the inside of the connecting sliding sleeve 311 is slidably connected with a connecting sliding rod 312, and the end of the connecting sliding rod 312 away from the connecting sliding sleeve 311 is hinged to the upper surface of the vibrating knife cutter 23.

[0051] In specific use, during the movement of the vibrating knife cutter 23 to the cutting position, the electric sliding block 341 moves forward and backward on the second sliding frame 343 synchronously with the vibrating knife cutter 23, and the second groove-shaped electric sliding seat 35 moves left and right on the machining base 1, so as to move the clamping piece 32 to the clamping position. When the vibrating knife cutter 23 moves downward, the vibrating knife cutter 23 drives the rotating disc 313 and the fixed seat 314 to move downward synchronously through the connecting sliding rod 312, and at this time, the fixed seat 314 drives the electric sliding block 341 and the second sliding frame 343 to move downward on the first sliding frame 342. When the vibrating knife cutter 23 moves in the forward and backward direction, the electric sliding block 341 stops moving to limit the clamping piece 32 in the forward and backward direction, at this time, the vibrating knife cutter 23 drives the connecting sliding rod 312 to slide in the connecting sliding sleeve 311. When the vibrating knife cutter 23 moves in the left and right direction, the electric sliding block 341 limits the clamping piece 32 in the left and right direction in cooperation with the second groove-shaped electric sliding seat 35, at this time, the vibrating knife cutter 23 drives the rotating disc 313 to rotate on the fixed seat 314 through the connecting sliding rod 312, and drives the connecting sliding rod 312 to slide in the connecting sliding sleeve 311 in the forward and backward direction, in cooperation with the rotating disc 313 rotating on the fixed seat 314, so that the vibrating knife cutter 23 can move in the forward and backward and left and right directions without being hindered, and the position of the clamping piece 32 remains unchanged when the vibrating knife cutter 23 cuts the ring.

[0052] As Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, the adjusting piece 33 comprises a mounting frame 331 fixedly connected to the lower surface of the fixed seat 314, the inner side of the mounting frame 331 is slidingly connected with two left-right symmetrical sliding blocks 332, the left and right side surfaces of the mounting frame 331 are both rotationally connected with adjusting screws 333, the two adjusting screws 333 correspond to the two sliding blocks 332 one by one, the opposite ends of the two adjusting screws 333 both penetrate to the inner side of the mounting frame 331 and are threadedly connected with the corresponding sliding blocks 332, the lower surface of the sliding block 332 is fixedly connected with two front-rear symmetrical telescopic connecting rods 334, the bottom ends of the two front-rear distributed telescopic connecting rods 334 are fixedly connected with an extrusion block 335, the center of the lower surface of the mounting frame 331 is fixedly connected with an elastic telescopic rod 336, and the mounting frame 331 is provided with scale lines for assisting the adjustment of the position of the sliding block 332 by the adjusting screw 333.

[0053] In specific use, when the adjusting piece 33 adjusts the position of the clamping piece 32, the sliding block 332 is moved on the mounting frame 331 by rotating the adjusting screw 333, and the scale lines on the mounting frame 331 are matched to adjust the distance between the two extrusion blocks 335 to be greater than the diameter of the cut ring, so that the position of the sliding block 332 is adjusted.

[0054] When the position of the sliding block 332 is adjusted, the position of the clamping piece 32 is adjusted synchronously with the sliding block 332, at this time, when the vibrating knife cutting machine 23 moves downward to drive the rotating disc 313 and the fixed seat 314 to move downward through the connecting slide rod 312, the mounting frame 331 moves downward synchronously with the fixed seat 314, first, the bottom end of the extrusion block 335 abuts against the position of the edge of the cut ring near the foam base material, and the bottom end of the elastic telescopic rod 336 abuts against the waste material at the center of the ring (as shown in the upper right corner of Figure 11 ).

[0055] With the continuous downward movement of the vibrating knife cutting machine 23, at this time, the extrusion block 335 generates an extrusion force on the foam base material, and the bottom end of the elastic telescopic rod 336 generates an extrusion force on the waste material at the center of the ring, and due to the reaction force of the foam on the extrusion block 335 and the elastic telescopic rod 336, the telescopic connecting rod 334 and the elastic telescopic rod 336 compress the extrusion block 335, so as to form an opening between the extrusion block 335 on the foam base material and the ring, facilitating the clamping of the ring by the clamping piece 32 (as shown in the upper left corner of Figure 11 ).

[0056] As shown in Figure 5 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the clamping piece 32 includes two sliding blocks 332, the lower surfaces of the two sliding blocks 332 are fixedly connected with two clamping plates 321 respectively, the opposite surfaces of the two clamping plates 321 are both provided with a plurality of mounting grooves 325 which are uniformly distributed in the up-down direction, the inside of the mounting groove 325 is elastically hinged with a clamping claw 322 through a torsion spring, in the normal state, the clamping claw 322 is arranged in an inclined manner and the top end thereof is away from the inside of the mounting groove 325, the front and rear inner walls of the mounting groove 325 are both provided with an arc-shaped limiting sliding groove 323, the inside of the arc-shaped limiting sliding groove 323 is slidably connected with a limiting sliding column 324, one end of the limiting sliding column 324 which is away from the arc-shaped limiting sliding groove 323 is fixedly connected with the clamping claw 322.

[0057] In specific use, when the extrusion block 335 forms an opening between the foam base material and the ring, at this time, as the mounting frame 331 continues to move downward, the telescopic connecting rod 334 and the elastic telescopic rod 336 continue to be compressed, and the clamping plate 321 is pushed to move downward, passes through the opening between the foam base material and the ring formed by the extrusion block 335, and is inserted between the foam base material and the ring (as shown in the lower left corner of FIG. 8). Figure 11

[0058] When the clamping plate 321 enters between the foam base material and the ring, the ring pushes the sliding block 332 to rotate into the mounting groove 325, when the vibration cutter cutting machine 23 completes a cutting work, the vibration cutter cutting machine 23 moves upward to drive the mounting frame 331 to move upward, at this time, the mounting frame 331 drives the clamping plate 321 to move upward, because the clamping claw 322 and the mounting groove 325 are elastically hinged, when the sliding block 332 rotates into the mounting groove 325, the torsion spring is deformed, the rebound force acting on the clamping claw 322 increases, at this time, the clamping claw 322 abuts against the outer circumferential surface of the ring, when the mounting frame 331 drives the clamping plate 321 to move upward, in cooperation with the plurality of clamping claws 322, the clamping plate 321 generates resistance to the ring when moving upward, so as to take the ring off the foam base material, and in cooperation with the elastic force of the elastic telescopic rod 336, when the clamping plate 321 drives the ring to move upward, the elastic telescopic rod 336 still generates downward thrust to the waste material at the center of the ring, as the ring moves upward, the thrust of the waste material by the elastic telescopic rod 336 makes the waste material separate from the ring (as shown in the lower right corner of FIG. 8). Figure 11 Figure 11 in the orientation shown in the legend of FIG. 8).

[0059] The arc-shaped limiting sliding groove 323 limits the rotation angle of the clamping claw 322, so that the clamping claw 322 remains in an inclined state, so as to smoothly enter between the foam base material and the ring to clamp the ring.

[0060] as shown in Figure 1 and Figure 12 ​​As shown, the conveying mechanism 4 comprises a second conveying member 42 arranged at the rear end of the right side of the second recess-shaped motorized slide 35, and a first conveying member 41 is arranged on the second recess-shaped motorized slide 35 and the second conveying member 42, and the rear surface of the second recess-shaped motorized slide 35 is fixedly installed with a second driving motor 43 through a motor base.

[0061] As shown in Figure 12 and Figure 13 , the first conveying member 41 comprises a support plate 415 fixedly connected to the right side of the second recess-shaped motorized slide 35, and the upper surface of the support plate 415 is slidably connected with a first belt conveyor 411 in the front-rear direction, the left side of the first belt conveyor 411 is fixedly connected with a rack 412, the top end of the output shaft of the second driving motor 43 is fixedly connected with a gear, the gear is engaged with the rack 412, the right side of the first belt conveyor 411 is fixedly connected with a limiting slide 414, the limiting slide 414 is slidably connected with the support plate 415 in the front-rear direction, and the upper surface of the first belt conveyor 411 is fixedly connected with two left-right symmetrical push rods 413.

[0063] In specific use, when the clamping plate 321 removes the ring from the foam substrate, at this time the second driving motor 43 rotates through the gear on it to cooperate with the rack 412 to drive the first belt conveyor 411 to move forward, the front end of the first belt conveyor 411 is moved to the lower side of the ring, and the first belt conveyor 411 is continuously driven to move forward, the ring clamped between the two clamping plates 321 is pushed forward by the push rod 413 to separate the ring from the clamping plate 321 and fall on the upper surface of the first belt conveyor 411, the ring is conveyed backward by the first belt conveyor 411 to make the ring product fall on the second belt conveyor 422, and the ring is conveyed to the next process by the second belt conveyor 422.

[0064] When the second driving motor 43 drives the first belt conveyor 411 to move forward, the limiting slide 414 on the support plate 415 slides and the bottom end of the first belt conveyor 411 slides on the support plate 415 at the same time, and the support slide column 423 at the rear end of the first belt conveyor 411 drives the auxiliary sliding groove 421 to slide, and the support plate 415 and the support slide column 423 support the first belt conveyor 411 when the first belt conveyor 411 slides, so that the first belt conveyor 411 can move more stably during the movement, and in order to reduce the sliding friction between the bottom end of the first belt conveyor 411 and the support plate 415, the support plate 415 can be embedded with a ball to change the sliding friction into rolling friction.

[0065] The processing method of the processing equipment for cutting the polyurethane material foam includes the following steps: S1, first, place the sheet-shaped polyurethane material foam to be cut on the upper surface of the processing base 1, and then adjust the relative distance between the two clamping plates 321 through the adjusting piece 33 according to the size of the cutting ring product.
