Description

Technical Field

[0001] The invention relates to the technical field of foam processing, in particular to a production and processing device and a processing method for polyurethane foam. Background Art

[0002] Foam is a lightweight, porous plastic material with excellent cushioning, heat insulation, sound insulation and sound absorption properties. Polyurethane foam is one of the types of foam. Polyurethane foam is made of isocyanate and polyol condensation foaming. It is soft and comfortable, elastic, wear-resistant and chemically resistant.

[0003] The foaming methods of polyurethane foam are divided into free foaming and model foaming. Free foaming is to inject the mixed raw materials directly into an open space or mold to allow them to expand and foam freely. The foamed polyurethane foam is then cut into sheets using a cutting device, and then the sheets are cut into the required shapes using a cutting device.

[0004] Usually, when producing ring-shaped products, batch cutting work is carried out on a sheet of foam substrate through cutting equipment. After all the cutting of a piece of foam substrate is completed, the ring product and the substrate are separated. Since the ring product is hollow in shape, after the ring is separated from the substrate, there will be waste in the hollow position of the ring that cannot be separated from the ring, and the staff needs to perform manual secondary separation, which affects the production efficiency of the ring product, resulting in the unsmoothness of the ring production process and the production efficiency of the ring.

[0012] According to an embodiment of the present invention, the auxiliary component includes a first sliding frame fixedly connected to the upper surface of the vertical section of the second groove-shaped electric slide seat, the two first sliding frames are slidably connected to a second sliding frame in the up and down directions, and the second sliding frame is slidably connected to an electric slider in the front and back directions.

DETAILED DESCRIPTION

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0041] like Figure 1 , Figure 2 and Figure 3As shown, a production and processing equipment of polyurethane foam includes a processing base 1, a cutting mechanism 2 is slidably arranged on the processing base 1, a clamping mechanism 3 is arranged on the processing base 1 and on the left side of the cutting mechanism 2, and a conveying mechanism 4 is arranged on the clamping mechanism 3.

[0042] like Figure 1 and Figure 4 As shown, the cutting mechanism 2 includes a first groove-shaped electric slide 25 slidably connected to the processing base 1 along the left-right direction, a displacement track 21 is fixedly connected between the opposite surfaces of the two vertical sections of the first groove-shaped electric slide 25, the horizontal section of the first groove-shaped electric slide 25 penetrates the base 1 front and back, an electric sleeve 22 is slidably connected to the displacement track 21 along the front-to-back direction, a vibration knife cutter 23 (the vibration knife cutter is the prior art) is limitedly slidably connected to the left side surface of the electric sleeve 22 along the up-and-down directions, a screw rod 24 arranged in the up-and-down directions is rotatably connected to the left side surface of the electric sleeve 22, the screw rod 24 is threadedly connected to the vibration knife cutter 23, a first drive motor is fixedly installed on the upper surface of the electric sleeve 22, and the output shaft of the first drive motor is fixedly connected to the top of the screw rod 24.

[0043] During specific use, the foam substrate to be cut is first placed on the upper surface of the processing base 1, and then the first groove-shaped electric slide 25 is moved in the left and right directions on the processing base 1, and the electric slide sleeve 22 is moved in the front and back directions on the displacement track 21 to move the vibrating knife cutter 23 to the starting cutting position, and then the first drive motor drives the screw rod 24 to rotate, so that the screw rod 24 drives the vibrating knife cutter 23 to move downward, and the vibrating knife cutter 23 is driven by the electric slide sleeve 22 to move in the front, back, left and right directions to start circular cutting on the foam substrate.

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

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

[0046] During specific use, before the vibrating knife cutter 23 starts to cut the foam substrate, the clamping size of the clamping member 32 is first adjusted through the adjusting member 33 according to the size of the circular ring to be cut. When the vibrating knife cutter 23 moves downward to start cutting, the vibrating knife cutter 23 drives the adjusting member 33 and the clamping member 32 to move downward synchronously through the linkage member 31. At this time, the clamping member 32 is located outside the foam substrate, that is, the clamping member 32 does not clamp the circular ring.

[0047] After the oscillating knife cutter 23 completes a circular cut, the oscillating knife cutter 23 moves to the next cutting position. At this time, the oscillating knife cutter 23 drives the clamping member 32 to move above the first cutting position of the oscillating knife cutter 23. Since the oscillating knife cutter 23 needs to perform two cutting strokes to complete a circular cut, that is, the oscillating knife cutter 23 needs to perform two vertical displacements. When the oscillating knife cutter 23 performs the first vertical displacement, the oscillating knife cutter 23 drives the clamping member 32 to move downward through the clamping member 32 to the second circular cutter. The ring at the first cutting position is clamped. When the vibrating knife cutter 23 completes a cutting stroke, the vibrating knife cutter 23 moves upward, and synchronously drives the clamping member 32 to move upward, so as to separate the ring cut off in the previous time from the foam substrate. Then, the ring clamped on the clamping member 32 is removed from the clamping member 32 through the conveying mechanism 4, and after being conveyed to the next process, the vibrating knife cutter 23 moves downward again to perform a second cutting stroke. The vibrating knife cutter 23 drives the clamping member 32 to move downward again, and the clamping member 32 at this time performs an empty clamping stroke.

[0048] After the vibration knife cutter 23 completes cutting a row of circular rings in the front-to-back direction on the foam substrate, the vibration knife cutter 23 needs to continue to move forward and perform an up-and-down displacement to drive the clamping member 32 to remove the frontmost circular ring in a row from the foam substrate. Then the vibration knife cutter 23 moves back to the rear end on the displacement track 21 and moves to the right through the first groove-shaped electric slide 25 to perform the next row of cutting work. This process is repeated in this way to cut multiple rows of batch circular ring products on the sheet-like polyurethane material foam substrate.

[0049] like Figure 5 As shown, the auxiliary component 34 includes a first sliding frame 342 fixedly connected to the upper surface of the vertical section of the second groove-shaped electric slide seat 35, and the two first sliding frames 342 are slidably connected to the second sliding frame 343 along the up and down direction, and the second sliding frame 343 is slidably connected to the electric slider 341 along the front and back direction.

[0050] like Figure 5 and Figure 6As shown, the linkage 31 includes a fixed seat 314 fixedly connected to the right side of the electric slider 341, the upper surface of the fixed seat 314 is rotatably connected to the turntable 313, the upper surface of the turntable 313 is fixedly connected to the connecting sleeve 311, the inner part of the connecting sleeve 311 is slidably connected to the connecting slide rod 312, and the end of the connecting slide rod 312 away from the connecting sleeve 311 is hinged to the upper surface of the vibrating knife cutter 23.

[0051] When in use, when the oscillating knife cutter 23 moves to the cutting position, the electric slider 341 moves synchronously with the oscillating knife cutter 23 on the second sliding frame 343 in the front-to-back direction, and the second groove-shaped electric slide seat 35 moves left-to-right on the processing base 1, so as to move the clamping member 32 to the clamping position. When the oscillating knife cutter 23 moves downward, the oscillating knife cutter 23 drives the turntable 313 and the fixed seat 314 to move downward synchronously through the connecting slide rod 312. At this time, the fixed seat 314 drives the electric slider 341 and the second sliding frame 343 to move downward on the first sliding frame 342. When the oscillating knife cutter 23 moves in the front-to-back direction, the electric slider 341 is powered off and stops moving to clamp the clamping member 32. The front and rear directions are limited, at this time, the vibrating knife cutter 23 drives the connecting slide bar 312 to slide inside the connecting slide sleeve 311; when the vibrating knife cutter 23 is displaced in the left and right directions, the electric slider 341 cooperates with the second groove-shaped electric slide seat 35 to limit the clamping member 32 in the left and right directions. At this time, the vibrating knife cutter 23 drives the turntable 313 to rotate on the fixed seat 314 through the connecting slide bar 312, and slides in the front and rear directions inside the connecting slide sleeve 311 by the connecting slide bar 312, and cooperates with the turntable 313 to rotate on the fixed seat 314, so that the vibrating knife cutter 23 can be displaced in the front and rear, left and right directions without obstruction, and ensure that the position of the clamping member 32 remains unchanged when the vibrating knife cutter 23 is performing circular cutting.

[0052] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the adjusting member 33 includes a mounting frame 331 fixedly connected to the lower surface of the fixing seat 314, and two left-right symmetrical sliding blocks 332 are slidably connected to the inner side of the mounting frame 331 along the left-right direction, and the left and right side surfaces of the mounting frame 331 are rotatably connected with adjusting screws 333, and the two adjusting screws 333 correspond to the two sliding blocks 332 one by one, and the opposite ends of the two adjusting screws 333 penetrate into the inner side of the mounting frame 331 and are threadedly connected to the corresponding sliding blocks 332, and the lower surface of the sliding block 332 is fixedly connected with two front-to-back symmetrical telescopic connecting rods 334, and the bottom ends of the two front-to-back distributed telescopic connecting rods 334 are commonly fixedly connected with an extrusion block 335, and 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 adjusting screws 333 to adjust the position of the sliding block 332.

[0053] During specific use, when the adjusting member 33 adjusts the position of the clamping member 32, the sliding block 332 is driven to move on the mounting frame 331 by rotating the adjusting screw 333, and the distance between the two extrusion blocks 335 is made larger than the diameter of the cut circular ring in conjunction with the scale lines on the mounting frame 331, thereby completing the adjustment of the position of the sliding block 332.

[0054] When the position adjustment of the sliding block 332 is completed, the position of the clamping member 32 is adjusted synchronously with the sliding block 332. At this time, when the vibrating knife cutter 23 moves downward and drives the turntable 313 and the fixing seat 314 to move downward through the connecting slide rod 312, the mounting frame 331 moves downward synchronously with the fixing seat 314. First, the bottom end of the squeezing block 335 contacts the edge of the circular ring cut on the foam substrate, and the bottom end of the elastic telescopic rod 336 contacts the waste material at the center of the circular ring (such as Fig.11 (see the legend in the upper right corner of the figure).

[0055] As the vibrating knife cutter 23 continues to move downward, the extrusion block 335 generates an extrusion force on the foam substrate, and at the same time, the bottom end of the elastic telescopic rod 336 generates an extrusion force on the waste material in the center of the ring. At the same time, due to the reaction force generated by 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, forming an opening between the position where the extrusion block 335 is squeezed on the foam substrate and the ring, so that the subsequent clamping member 32 can clamp the ring (such as Fig.11 (see the legend in the upper left corner of the figure).

[0056] like Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the clamping member 32 includes two clamping plates 321 fixedly connected to the lower surfaces of the two sliding blocks 332, and a plurality of mounting grooves 325 evenly distributed in the up-and-down directions are provided on the opposite surfaces of the two clamping plates 321. The interior of the mounting groove 325 is elastically hinged with a clamping claw 322 through a torsion spring. In a normal state, the clamping claw 322 is inclined and its top end is away from the internal direction of the mounting groove 325. The front and rear inner walls of the mounting groove 325 are provided with an arc-shaped limiting sliding groove 323, and the internal sliding connection of the arc-shaped limiting sliding groove 323 is a limiting sliding column 324, and the end of the limiting sliding column 324 away from the arc-shaped limiting sliding groove 323 is fixedly connected to the clamping claw 322.

[0057] In specific use, after the extrusion block 335 forms an opening between the foam substrate and the circular ring, as the mounting frame 331 continues to move downward, the telescopic connecting rod 334 and the elastic telescopic rod 336 are pushed to continue to be compressed, and at the same time, the clamping plate 321 is pushed downward to pass through the opening formed between the foam substrate and the circular ring by the extrusion block 335, and to be inserted between the foam substrate and the circular ring (such as Fig.11 (see figure in the lower left corner of the figure).

[0058] When the clamping plate 321 enters between the foam substrate and the ring, the ring pushes the sliding block 332 to rotate into the installation groove 325. When the vibrating knife cutter 23 completes a cutting work, the vibrating knife cutter 23 moves upward to drive the installation frame 331 to move upward. At this time, the installation frame 331 drives the clamping plate 321 to move upward. Since the clamping claw 322 and the installation groove 325 are elastically hinged, when the sliding block 332 rotates into the installation groove 325, the torsion spring is deformed, and the rebound force acting on the clamping claw 322 increases. At this time, the clamping claw The mounting frame 331 drives the clamping plate 321 to move upward, and the clamping claws 322 cooperate with each other to generate resistance to the ring when the clamping plate 321 moves upward, so that the ring can be removed from the foam substrate. In addition, the elastic force of the elastic telescopic rod 336 is cooperated 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 a downward thrust on the waste material at the center of the ring. As the ring moves upward, the thrust given to the waste material by the elastic telescopic rod 336 separates the waste material from the ring (such as Fig.11 As shown in the figure in the lower right corner, Fig.11 The directions in the figure are subject to the marked directions).

[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 that it can smoothly enter between the foam substrate and the annular ring to clamp the annular ring.

[0060] like Figure 1 and Fig.12As shown, the conveying mechanism 4 includes a second conveying member 42 arranged at the rear end of the right side surface of the second groove-shaped electric slide 35, and the first conveying member 41 is commonly arranged on the second groove-shaped electric slide 35 and the second conveying member 42, and the rear surface of the second groove-shaped electric slide 35 is fixedly mounted with a second driving motor 43 through a motor seat.

[0061] like Fig.12 and Fig.13 As shown, the first conveying member 41 includes a support plate 415 fixedly connected to the right side of the second groove-shaped electric slide 35, the upper surface of the support plate 415 is slidably connected to the first belt conveyor 411 along the front-to-back direction, the left side of the first belt conveyor 411 is fixedly connected to a rack 412, the top end of the output shaft of the second drive motor 43 is fixedly connected to a gear, the gear is meshed with the rack 412, the right side of the first belt conveyor 411 is fixedly connected to a limiting slide 414, the limiting slide 414 is slidably connected to the support plate 415 along the front-to-back direction, and the upper surface of the first belt conveyor 411 is fixedly connected to two left-right symmetrical push rods 413.

[0062] like Fig.12 , Fig.13 and Fig.14 As shown, the second conveying member 42 includes a second belt conveyor 422 fixedly connected to the right side of the second groove-shaped electric slide 35, and two left-right symmetrical auxiliary slide grooves 421 are provided on the second belt conveyor 422. The interior of the auxiliary slide groove 421 is slidably connected with a support slide column 423 along the front-back direction, and the bottom end of the support slide column 423 is rotatably connected with an auxiliary roller 424 that changes the sliding friction between the support slide column 423 and the auxiliary slide groove 421 from rolling friction, and the top end of the support slide column 423 is fixedly connected to the rear end of the first belt conveyor 411.

[0063] During specific use, when the clamping plate 321 removes the ring from the foam substrate, the second drive motor 43 rotates through the gear and rack 412 thereon to drive the first belt conveyor 411 to move forward, and after the front end of the first belt conveyor 411 is moved to the bottom of the ring, the first belt conveyor 411 continues to be driven forward, and the ring clamped between the two clamping plates 321 is pushed forward by the push rod 413 so that the ring is separated from the clamping plate 321 and falls on the upper surface of the first belt conveyor 411, and the ring is transported backward by the first belt conveyor 411 so that the ring product falls on the second belt conveyor 422, and the ring is transported 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 bar 414 slides on the support plate 415 and the bottom end of the first belt conveyor 411 slides on the support plate 415. At the same time, the rear end of the first belt conveyor 411 drives the support slide column 423 to slide inside the auxiliary slide groove 421. 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 be more stable during the movement. In order to reduce the sliding friction between the bottom end of the first belt conveyor 411 and the support plate 415, a ball bearing can be embedded in the support plate 415 to convert the sliding friction into rolling friction.

[0065] The processing method for cutting polyurethane foam using the above-mentioned processing equipment includes the following steps: S1. First, place the sheet of polyurethane 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 adjustment member 33 according to the size of the cut circular ring product.

[0066] S2, and then the cutting mechanism 2 moves on the processing base 1 to start cutting the sheet-like polyurethane foam substrate into batches of circular products.
