Description

TECHNICAL FIELD

[0001] The application belongs to the field of cutting, in particular to a PP hollow plate shaping cutting device. BACKGROUND

[0002] PP hollow plate is also called plastic hollow plate, which is formed by mixing polypropylene and polyethylene in a certain proportion and then extruding by a plate drawing machine. The cross section of the PP hollow plate is lattice-shaped. The PP hollow plate is often used to make pallets, turnover boxes and lining boards, etc. In the process of processing the PP hollow plate into a turnover box, a shaping cutting device is needed to cut the PP hollow plate into a specified shape.

[0003] A patent application with publication number CN111185950A discloses a plastic-wood board cutting and recycling integrated equipment, which comprises a crushing box, an operation table, a filter frame, a sleeve rod and a fixing ring. The crushing box is provided with an inlet at the top end. The third drive motor is fixedly connected to the outside of the crushing box. The output shaft of the third drive motor is fixedly connected to the rotating shaft. The supporting plate is provided with a sliding groove. The filter frame is fixedly connected to an L-shaped plate at one end close to the third drive motor. The second drive motor is fixedly connected to the outside of the crushing box. The output shaft of the second drive motor is fixedly connected to the rotating plate. The rotating plate is fixedly connected to a connecting rod at one end away from the second drive motor. The plastic-wood board cutting and recycling integrated equipment can recycle and crush the generated waste and small wood blocks for reprocessing into wood boards through the setting of the dust collector, the conduit, the crushing box and the crushing roller.

[0004] The sidewall of the turnover box is usually provided with two hand holes for taking the turnover box. When processing the PP hollow plate, two hand holes need to be cut on the hollow plate. Since the size of the cut-off hollow plate scrap is larger than that of some small pallets, the cut-off hollow plate scrap can be recycled and cut for processing without being crushed for processing. The above scheme can only use the dust collector to uniformly crush and recycle some small waste and small wood blocks. The dust collector cannot suck some large wood blocks. If the size of the dust collector inlet is changed, a larger power is needed to drive the normal operation of the dust collector. During the process of sucking the scrap into the dust collector, the scrap may be folded, resulting in folds on the scrap.

[0005] Therefore, the application provides a PP hollow plate shaping cutting device. SUMMARY

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments. Embodiment one

[0033] As Figures 1-9As shown in the figure, the PP hollow plate shaping and cutting device provided by the embodiment of the application comprises a cutting machine body 1, further comprises a conveying belt 2 installed on the cutting machine body 1, the conveying belt 2 is used for conveying the hollow plate; a first slide rail 3 slidably installed on the cutting machine body 1; a cutting head 4 slidably installed on the first slide rail 3, the cutting head 4 is used for cutting the hollow plate; a collecting groove 5 installed on the side wall of the cutting machine body 1, the collecting groove 5 is used for collecting the cut hollow plate; a second slide rail 6 slidably installed on the cutting machine body 1 and the collecting groove 5; a suction device 7 slidably installed on the second slide rail 6; a first telescopic block 8 slidably installed on the second slide rail 6; a sliding block 9 installed on the first telescopic block 8; a first suction assembly 10 installed on the lower surface of the sliding block 9, the first suction assembly 10 comprises: a first connecting plate 101 fixedly installed on the lower surface of the sliding block 9; two sliding plates 102 installed on the first connecting plate 101, the sliding plates 102 are provided with suction cups 103, the suction cups 103 are provided with rubber pipes 104, the suction cups 103 are communicated with the suction device 7 through the rubber pipes 104, and the suction cups 103 are used for sucking the cut hollow plate.

[0034] Specifically, the suction device 7 is a small vacuum suction machine, the suction cup 103 is matched with the suction device 7, the cutting machine body 1 and the cutting head 4 adopt a vibration type cutting machine structure, in which the first slide rail 3 and the second slide rail 6 are moved forward and backward relative to the cutting machine body 1, the cutting head 4, the suction device 7 and the first telescopic block 8 are moved left and right relative to the cutting machine, the side where the collecting groove 5 is located is the right side, the side where the first slide rail 3 is located is the front side, the first slide rail 3, the second slide rail 6, the cutting head 4 and the suction device 7 are electrically driven, the first telescopic block 8 is electrically driven, the first telescopic block 8 can be telescoped up and down relative to the cutting machine body 1, and the PP hole plate can be used for manufacturing a storage box. Figure 1 Generally, an oval hole needs to be formed on the two sides of the storage box so as to be convenient for taking, and therefore, a cutting machine needs to be used to cut the PP hollow plate in the manufacturing process, and the oval hole is cut on the PP hollow plate, as shown in the initial state. Figure 1

[0035] ​In operation, the PP hollow plate is placed on the upper surface of the front end of the conveying belt 2, then the first slide rail 3 is controlled to move backward, driving the cutting head 4 to move backward, at the same time, the cutting head 4 moves left on the first slide rail 3 until the cutting head 4 is above the left of the hollow plate, then the first slide rail 3 is controlled to move forward and backward, the cutting head 4 is controlled to move left and right on the first slide rail 3, so that the track of the cutting head 4 is an ellipse, and the cutting head 4 is controlled to vibrate up and down at high speed relative to the hollow plate, so that the hollow plate is cut and shaped under the action of pressure, after an ellipse is cut on the hollow plate, the cutting head 4 is moved to the right upper side of the hollow plate, then the ellipse cutting on the hollow plate is repeated, after the cutting is completed, the action of cutting and shaping one hollow plate is completed, then the conveying belt 2 is controlled to move backward, driving the hollow plate to move backward, at this time, a new hollow plate is placed on the conveying belt 2, so as to realize the cyclic operation, and the batch cutting and shaping of the hollow plate is realized;

[0036] The existing device using the dust collector can only uniformly crush and recycle some small leftover materials. The size of the cut oval leftover material is too large to be normally sucked. If the size of the inlet of the dust collector is changed, larger power is needed to drive the normal operation of the dust collector. During the process of sucking the leftover material into the dust collector, the leftover material may be folded, resulting in creases on the leftover material. After the cutting of a hollow plate is completed, the transmission belt 2 is started to move backward until the leftover material is located in the moving range of the first telescopic block 8. A new hollow plate is placed on the transmission belt 2 for cutting action. At the same time, the first telescopic block 8 is controlled to move to the left of the leftover material. The first telescopic block 8 is started to extend downward to drive the sliding block 9 and the first suction assembly 10 to move downward until the suction disc 103 on the first suction assembly 10 is tightly attached to the leftover material. Then the suction device 7 is started to suck. Since the suction disc 103 is connected with the suction device 7 through the rubber pipe 104, the air in the suction disc 103 is sucked away, so that the leftover material is adsorbed on the suction disc 103, that is, the action of sucking the leftover material is realized. Then the first telescopic block 8 is controlled to move upward to the initial state to drive the first suction assembly 10 and the leftover material to move upward synchronously. At this time, the leftover material is separated from the hollow plate. Then the first telescopic block 8 is controlled to move to the right to drive the suction assembly and the leftover material to the upper side of the collecting groove 5. Then the suction device 7 is controlled to stop working. At this time, air enters the suction disc 103, and the leftover material falls from the suction disc 103 to the collecting groove 5, that is, the action of collecting the leftover material is realized. The first telescopic block 8 is slid to the left to the upper side of the right leftover material. After repeating the operations of sucking and collecting the leftover material, the action of sucking and collecting the leftover material in a hollow plate is completed. When the cutting head 4 completes the cutting of a new hollow plate, the transmission belt 2 is started to move backward until a new cut hollow plate is located below the first telescopic block 8. In this way, the action of batch sucking and collecting the leftover material is realized. By arranging the first suction assembly 10, the cut leftover material can be transferred to the collecting groove 5 for secondary recycling, which is more environmentally friendly and saves costs. The adsorption of the suction disc on the leftover material will not cause creases on the leftover material. The cut oval leftover material can be processed into small-size battens without crushing and reprocessing, which reduces the processing steps and saves costs. For the same batch of cut hollow plates, the sizes of the leftover materials in the collecting groove 5 are consistent, and there is no need to classify the sizes of the leftover materials, which is convenient to use.

[0037] As shown in Figure 4 The sliding plate 102 is slidably connected with the first connecting plate 101. Two gears 105 are rotatably connected with the sliding plate 102. The two gears 105 are meshingly connected with the two sliding plates 102.

[0038] Specifically, in Figure 4In the middle, the sliding plate 102 moves horizontally forward and backward relative to the first connecting plate 101, rotates the first gear 105, and can drive the sliding plate 102 to move forward and backward, so that the suction cups 103 move forward and backward synchronously. By arranging the first gear 105, the forward and backward positions of the suction cups 103 relative to the first connecting plate 101 can be controlled, that is, the distance between the two suction cups 103 is controlled to adapt to oval-shaped corner scraps of different sizes, and the practicability is stronger.

[0039] As Figures 2-7 As shown, it also includes a first spring 11 installed between the sliding block 9 and the first telescopic block 8, the sliding block 9 and the first telescopic block 8 are in sliding connection; a switch 12 installed on the first telescopic block 8, the switch 12 is located in the moving range of the sliding block 9; a monitoring 13 slidingly installed on the second slide rail 6, the switch 12 is used to control the start and stop of the monitoring 13.

[0040] Specifically, the switch 12 adopts a press trigger type. Due to the wear of the cutting head 4 and other reasons, after the cutting is completed, there is a connection between the leftover material and the hollow plate, that is, the leftover material is not completely cut off. At this time, the suction cup 103 cannot normally load the leftover material into the collection groove 5. If forced operation is performed, the hollow plate is damaged. The first telescopic block 8 is composed of two parts. One part is not movable in the vertical plane relative to the second sliding rail 6. The other part is movable up and down relative to the second sliding rail 6. The sliding block 9 slides up and down on the movable part of the first telescopic block 8. The switch 12 is arranged on the movable part of the first telescopic block 8. When the operation of sucking the leftover material is completed, the first telescopic block 8 can be controlled to shrink upward, driving the sliding block 9 and the leftover material to move upward. If the leftover material is not completely cut off, the leftover material is pulled by the hollow plate after moving a distance, and the leftover material remains stationary, driving the sliding block 9 to stop moving synchronously. At this time, the first telescopic block 8 continues to shrink upward, and the first spring 11 is squeezed and shrinks. When the switch 12 on the movable part of the first telescopic block 8 contacts and triggers the sliding block 9, the monitoring 13 is started to observe the leftover material on the suction cup 103 to check whether the leftover material is completely cut off. If the leftover material is not completely cut off, the first telescopic block 8 is controlled to extend downward until the leftover material returns to the initial position. Then the suction device 7 is controlled to stop suction, that is, the suction cup 103 stops adsorbing the leftover material. The first sliding rail 3 is moved backward, driving the first suction assembly 10 to move away from the leftover material. After the cutting head 4 cuts one leftover material, the cutting head 4 is moved backward to above the leftover material for secondary cutting. Then the cutting head 4 and the suction assembly are moved forward to the initial state. The first telescopic block 8 is controlled to move downward to perform the action of sucking the leftover material. If the leftover material has been completely cut off, the position of the suction assembly may be incorrect, and the suction cup 103 is adsorbed to the hollow plate. At this time, the suction device 7 is controlled to stop suction, and the suction cup 103 no longer adsorbs the hollow plate. Then the first telescopic block 8 is controlled to move left and right to adjust the position of the first telescopic block 8. Then the action of sucking is repeated to avoid the above problems. If the switch 12 is triggered multiple times, the cutting head 4 is damaged. At this time, the cutting head 4 is replaced.

[0041] As Figures 2-7 shown, further comprising: a round rod 14 fixedly installed on the upper surface of the first telescopic block 8; a third sliding rail 15 fixedly installed on the upper surface of the round rod 14; two pressing rods 16 installed on the third sliding rail 15, and the two pressing rods 16 are symmetrically distributed on both sides of the second sliding rail 6.

[0042] Specific, round rod 14 is telescopic, can be relative to the second sliding rail 6 up and down telescopic for some need in many places cutting hollow plate, can be hollow plate cutting and suction operation at the same time, if the switch 12 is triggered, the suction cup 103 in the process of moving up will bring the hollow plate in the vicinity of the scrap near the edge, if the cutting position of cutting head 4 is close to the scrap, then will affect the cutting of cutting head 4, the initial state, the press rod 16 is located in the front and back of the scrap, before suction scrap, control round rod 14 down, drive the third sliding rail 15 and press rod 16 to move down, so that the press rod 16 on the hollow plate, in the position of the two sides of the scrap, produce a downward pressing force, to ensure that the cutting head 4 can normally cut the hollow plate, to ensure the quality of the product after cutting, improve the above problems.

[0043] As shown in Figures 2-7 , the press rod 16 and the third sliding rail 15 are slidably installed, the second spring 17 is installed on the third sliding rail 15, one end of the second spring 17 is connected with the press rod 16, and the other end of the second spring 17 is connected with the third sliding rail 15.

[0044] Specific, press rod 16 moves back and forth relative to the third sliding rail 15, the press rod 16 is in contact with both ends of the sliding plate 102, the initial state, the second spring 17 is in tension, the second spring 17 makes the press rod 16 always fit with the sliding plate 102, when the sliding plate 102 is adjusted to adjust the position of the suction cup 103, the sliding plate 102 moves can synchronously push the press rod 16 to move, so that the press rod 16 can adapt to different size of scrap, more practical.

[0045] As shown in Figures 2-7 , the press rod 16 and the sliding rod 18 are slidably installed, the third spring 19 is installed between the press rod 16 and the sliding rod 18, the second telescopic block 20 is installed on the press rod 16, and the other end of the second telescopic block 20 is connected with the first telescopic block 8.

[0046] Specifically, the second telescopic block 20 is horizontally telescopic relative to the first telescopic block 8, the second telescopic block 20 enables the pressing rod 16 to be connected with the first telescopic block 8 after moving, the slide rod 18 slides up and down relative to the pressing rod 16, the second telescopic block 20 is connected with the part of the first telescopic block 8 that can move up and down, in the initial state, the lower surface of the slide rod 18 is lower than the lower surface of the suction disc 103, before sucking the leftover material, the first telescopic block 8 is controlled to extend downward, driving the second telescopic block 20 and the suction disc 103 to move downward, the second telescopic block 20 drives the pressing rod 16 and the slide rod 18 to move downward, in the process of the first telescopic block 8 extending downward, the slide rod 18 first contacts the hollow plate, then the third spring 19 is compressed, when the suction disc 103 contacts the hollow plate, the slide rod 18 generates a certain pressure on the hollow plate, then the suction device 7 is controlled to start, the suction disc 103 adsorbs the leftover material, the first telescopic block 8 is controlled to shrink upward, driving the suction disc 103, the second telescopic block 20 and the leftover material to move upward, so that the pressing rod 16 moves upward, at this time, the slide rod 18 remains stationary under the action of the elastic force of the third spring 19, when the leftover material is separated from the hollow plate by a distance, the slide rod 18 moves upward with the pressing rod 16, the pressing rod 16 is driven to move up and down by the moving force of the first telescopic block 8, without the need to set an additional power source to drive the pressing rod 16 to move.

[0047] As shown in Figures 2-7 , further comprising: a second suction assembly 21 installed on the first suction assembly 10, the second suction assembly 21 is consistent with the structure of the first suction assembly 10.

[0048] Specifically, the second suction assembly 21 is vertically placed between the first suction assembly 10, the lower surface of the suction disc 103 of the second suction assembly 21 is consistent with the lower surface of the suction disc 103 of the first suction assembly 10, by setting two groups of suction assemblies, the suction assembly can adapt to more different shapes of leftover materials cut from the hollow plate, and the practicality is strong.

[0049] As shown in Figures 2-7 , further comprising: a spray head 22 installed on the first slide rail 3, the spray head 22 is used for spraying water flow to cool the cutting head 4; a round block 23 slidingly installed on the slide rod 18; a concave plate 24 used for wiping the hollow plate, the lower surface of the concave plate 24 is installed with a cotton block, and the two ends of the concave plate 24 are respectively rotationally connected with two round blocks 23.

[0050] Specifically, the round block 23 slides left and right relative to the slide rod 18, the round block 23 is electrically driven, the rotation of the concave plate 24 is electrically controlled, the part of the concave plate 24 that is concave is telescopic, and can automatically expand and contract with the increase and decrease of the distance between the two slide rods 18, so as to adapt to different sizes of leftover materials. Since the temperature of the cutting head 4 will rise after long-time work, the melting point of the material of the PP hollow plate is relatively low, and the cutting part of the PP hollow plate will melt after the temperature of the cutting head 4 rises. When the cutting head 4 is cutting, the nozzle 22 sprays water on the cutting head 4 to cool it down. After the cutting is completed, the water on the hollow plate may cause the suction cup 103 to fail to normally suck the leftover materials. When the leftover materials are located below the first telescopic block 8, the first telescopic block 8 extends downward, drives the second telescopic block 20 to move downward, and makes the pressing rod 16 and the slide rod 18 move downward, thereby driving the round block 23 and the concave plate 24 to move downward. When the concave plate 24 contacts the hollow plate, the first telescopic block 8 stops moving downward, the round block 23 is controlled to move back and forth, and in the moving process, the cotton block can absorb the water on the hollow plate. When the concave plate 24 is located above the left side of the slide rod 18 again, the round block 23 and the concave plate 24 are controlled to rotate to the upper left of the concave plate 24, that is, the wiping action of the hollow plate is completed, and the above problems are avoided.

[0053] As Figures 3-4 shown, comparative example one, wherein another embodiment of the application is: the suction cup 103 is threadedly connected with the slide plate 102, the slide plate 102 is provided with a plurality of threaded holes 27 for connecting the suction cup 103, and the suction device 7 is provided with a plurality of round holes 28 connected with the rubber pipe 104.

[0054] Specifically, by providing a plurality of threaded holes 27 and round holes 28, a plurality of suction cups 103 can be installed on the slide plate 102, so that the suction assembly can be more firmly adsorbed for some large-size leftover materials.

[0055] Working steps:

[0056] Step one, place the PP hollow plate on the upper surface of the front end of the conveying belt 2, then control the first slide rail 3 to move backward, drive the cutting head 4 to move backward, at the same time, the cutting head 4 moves left on the first slide rail 3 until the cutting head 4 is above the left of the hollow plate, then control the first slide rail 3 to move forward and backward, control the cutting head 4 to move left and right on the first slide rail 3, so that the trajectory of the cutting head 4 is an ellipse, and control the cutting head 4 to vibrate up and down at high speed relative to the hollow plate, under the action of pressure, the hollow plate is shaped and cut, after cutting an ellipse on the hollow plate, move the cutting head 4 to the right upper side of the hollow plate, then repeat the cutting of the ellipse on the hollow plate, after cutting is completed, the action of shaping and cutting one hollow plate is completed, then control the conveying belt 2 to move backward, drive the hollow plate to move backward, at this time, a new hollow plate is placed on the conveying belt 2, so as to realize the batch shaping and cutting of the hollow plate;

[0057] Step two, when the cut-off edge scraps are below the first telescopic block 8, control the first telescopic block 8 to extend downward, drive the second telescopic block 20 to move downward, so that the pressure rod 16 and the slide rod 18 move downward, drive the circular block 23 and the concave plate 24 to move downward, when the concave plate 24 contacts the hollow plate, the first telescopic block 8 stops moving downward, control the circular block 23 to move left and right, in the moving process, the cotton block can absorb water on the hollow plate, when the concave plate 24 is located at the left upper side of the concave plate 24 again, control the circular block 23 to rotate to the left upper side of the concave plate 24, that is, the action of wiping the hollow plate is completed;

[0058] Step three, control the first telescopic block 8 to continue to extend downward, drive the second telescopic block 20 and the suction cup 103 to move downward, the second telescopic block 20 drives the pressure rod 16 and the slide rod 18 to move downward, because the lower surface of the slide rod 18 is lower than the lower surface of the suction cup 103, in the process of extending downward of the first telescopic block 8, the slide rod 18 first contacts the hollow plate, then the third spring 19 is compressed, at this time, the slide rod 18 generates a downward pressing force on the hollow plate, that is, the action of pressing the hollow plate is realized;

[0059] Step four, when the suction cup 103 is attached to the scrap, start the suction device 7 to suck, because the suction cup 103 is connected with the suction device 7 through the rubber tube 104, so the air in the suction cup 103 is sucked, at this time the air pressure in the suction cup 103 is lower than the atmospheric pressure, under the extrusion of the atmospheric pressure, the scrap is adsorbed on the suction cup 103, that is, the action of sucking the scrap is realized, then control the first telescopic block 8 to move upward to the initial state, drive the suction assembly and the scrap to move upward synchronously, at this time the scrap is separated from the hollow plate, then control the first telescopic block 8 to move right, drive the suction assembly and the scrap to the above of the collecting groove 5, then control the suction device 7 to stop working, at this time the air enters the suction cup 103, the pressure in the suction cup 103 is consistent with the outside air pressure, the scrap falls from the suction cup 103 to the collecting groove 5, that is, the action of collecting the scrap is realized;

[0060] Step five, in the process of the first telescopic block 8 shrinking upward, the sliding block 9 moves upward synchronously with the scrap, if the scrap is not completely cut off, the scrap will be pulled by the hollow plate after moving a distance, the scrap will stop moving, the sliding block 9 will stop moving synchronously, at this time the first telescopic block 8 continues to shrink upward, at this time the first spring 11 is extruded and shrinks, when the switch 12 on the movable part of the first telescopic block 8 contacts and triggers the sliding block 9, at this time the monitor 13 starts to observe the scrap on the suction cup 103, to check whether the scrap is completely cut off, if not, control the first telescopic block 8 to extend downward, to the initial position of the scrap, then control the suction device 7 to stop sucking, that is, the suction cup 103 stops adsorbing the scrap, move the first sliding rail 3 backward, drive the first suction assembly 10 away from the scrap, after the cutting head 4 cuts one scrap, move the cutting head 4 backward to the above of the scrap for secondary cutting, then move the cutting head 4 and the suction assembly forward to the initial state, continue to control the first telescopic block 8 to move downward to suck the scrap, if the scrap has been completely cut off, it may be that the position of the suction assembly is not correct, the suction cup 103 is adsorbed to the hollow plate, at this time the suction device 7 can be controlled to stop sucking, the suction cup 103 no longer adsorbs the hollow plate, then control the first telescopic block 8 to move left and right to adjust the position of the first telescopic block 8, and then repeat the action of sucking;

[0061] Step six, when the first telescopic block 8 moves to the collecting groove 5 above, the control recessed plate 24 rotates to the lower side of the slide rod 18, at this time the recessed plate 24 is above the collecting plate 25, the control telescopic rod 26 moves upward, drives the collecting plate 25 to move upward, until the recessed plate 24 and the collecting plate 25 are close, because the recessed plate 24 remains stationary, the upper end of the telescopic rod 26 is under the reverse action of the recessed plate 24 and shrinks downward, at this time the collecting plate 25 is horizontal, the water cup on the recessed plate 24 is extruded to the collecting plate 25, then the telescopic rod 26 is controlled to shrink downward, drives the recessed plate 24 to move downward, in this process, the upper end of the telescopic rod 26 is restored to the initial state under the action of the spring force, so that the water on the collecting plate 25 flows downward along the inclined surface of the collecting plate 25 into the connecting pipe, the water on the recessed plate 24 can be extruded and sent back to the cutting machine body 1 for the nozzle 22 to use again;

[0062] Step seven, slide the first telescopic block 8 to the right side edge material above, after repeating the operation of sucking and collecting the edge material, the operation of sucking and collecting the edge material in a hollow plate is completed, at the same time the cutting head 4 cuts a new hollow plate, then the transmission belt 2 is started to move backward, until a new cutting hollow plate is located below the first telescopic block 8, so as to realize the operation of batch sucking and collecting the edge material.
