Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, and in particular to an EVA anti-static foam laser cutting machine. Background Art

[0002] EVA anti-static foam is usually based on EVA foaming. A certain amount of conductive carbon powder and other conductive materials are added during the foaming process, and then molded by an instrument. EVA anti-static foam is often used to make packaging boxes for plug-in boards and printed circuit boards, as well as anti-static cushioning pads and turnover packaging for electronic devices and production lines. It can also be used as an electromagnetic shielding material for computer rooms, which can effectively protect integrated circuits, microelectronic components, optoelectronic active devices, high-frequency filters, etc. from the hazards of static electricity, vibration, and impact.

[0003] When using EVA anti-static foam, you need to use a laser cutting machine to cut a suitable load-bearing structure on the foam board first; but after cutting, since the foam is a flexible and elastic structure, the foam product cannot be automatically separated from the foam waste, and the two are still connected as one. It is necessary to manually separate the foam waste from the foam product and then classify and output it. This increases the laser cutting production process and reduces the laser cutting production efficiency. Summary of the invention

[0056] A main frame 3 is laterally slidably mounted on the top of the first transverse guide rail 1;

[0057] The inner restraint assembly 4 comprises an inner frame 41, a rotating shaft 42, a longitudinal slide plate 43 and a clamping angle plate 44; the inner frame 41 is provided with a rotating shaft 42 at the middle of both ends, the rotating shaft 42 is rotatably connected to the transverse midline of the outer frame, one end of the main frame 3 is provided with a first motor 46 that drives the inner frame 41 to rotate, two groups of longitudinal slide plates 43 are symmetrically slidably arranged on the surface of the inner frame 41 in transverse direction, and two groups of clamping angle plates 44 are symmetrically slidably arranged on the surface of the longitudinal slide plate 43 in longitudinal direction, and the clamping angle plates 44 are used to clamp and position the four corners of the foam plate;

[0058] A lifting assembly 5, which is slidably mounted on the bottom surface of the inner frame 41;

[0059] The puncture and material extraction component 6 is installed above the inner frame 41;

[0060] A negative pressure suction assembly 7, which is installed on the side of the laser cutting head 23;

[0061] A crushing and recovery component 8 is arranged on one side of the transverse guide rail, and is used to recover the foam waste output by the puncture and material collection component 6 and the negative pressure suction component 7;

[0062] The foam laser cutting machine includes the following working modes:

[0063] In the first mode, the foam cut out by the laser is waste material, and the remaining foam frame is product material: the material pushing component 5 is adjusted to the narrow contact mode and pushes up the foam waste material, and the negative pressure material suction component 7 sucks the ejected foam waste material and guides it to the crushing and recycling component 8; after the foam waste material is guided out, the inner frame 41 rotates to release the foam product to the discharge conveyor belt 11;

[0064] In the second mode, the foam cut by the laser is the product material and the remaining foam frame is the waste material: the puncture and material collection component 6 is adjusted to the plane mode to press the foam product to the discharge conveyor belt 11; after the foam product is discharged, the puncture and material collection component 6 is adjusted to the puncture mode and moved above the puncture position of the foam frame, the lifting component 5 is adjusted to the wide contact mode and moved below the puncture part of the foam frame, the lifting component 5 stably supports the puncture part from the bottom so that the puncture and material collection component 6 can smoothly pass through the foam frame, and the puncture and material collection component 6 is lifted up and moved outward to transfer the foam frame to the crushing and recovery component 8.

[0065] In the above scheme:

[0066] 1. The setting of internal constraint components can achieve the following effects:

[0067] 1.1. The two sets of longitudinal slide plates can slide horizontally for primary adjustment, and the clamping angle plates can slide longitudinally for secondary adjustment. In this way, foam boards of different sizes can be constrained and positioned;

[0068] 1.2. The first motor can drive the inner frame to rotate to meet the requirements of foam frame product unloading;

[0069] 2. The composite cooling component can be used to perform air cooling and water cooling on the laser cutting head, effectively reducing the working temperature of the laser cutting head and ensuring stable operation of the laser cutting head;

[0070] 3. The setting of the top material component can achieve the following effects:

[0071] 3.1. It can be adjusted to a narrow contact mode, and in the first mode, it can stably push up the small-sized foam waste cut by the laser, so that the negative pressure suction component can quickly suck it away;

[0072] 3.2. It can be adjusted to a wide contact mode. In the second mode, the foam frame can be pushed up from below to prevent the foam frame from being deformed downward when the puncture and material collection component punctures, thereby improving the puncture speed and smoothness of the puncture and material collection component;

[0073] 4. The setting of the puncture and material collection component can achieve the following effects:

[0074] 4.1. In the second mode, the puncture and material collection component can be adjusted to a plane mode, so that the cut small-sized foam products can be pressed down to separate the foam products from the foam frame, thereby achieving rapid material collection;

[0075] 4.2. In the second mode, since the foam frame is waste material and is large in size, it cannot be directly sucked by the negative pressure suction component. Therefore, the puncture and material collection component is designed to be adjusted to the puncture mode. In this way, the puncture and material collection component can pass through the foam frame, and then when the puncture and material collection component is lifted up, the foam frame can be taken away to the crushing and recovery component to achieve rapid recovery;

[0076] 5. The negative pressure suction component can absorb small-sized foam waste, and can also extract the working heat of the laser cutting head during operation, thereby helping to reduce the working temperature of the laser cutting head.

[0077] In this embodiment, the angle clamping plate 44 is L-shaped, a middle slide groove 431 is provided inside the longitudinal slide plate 43, a first moving block 442 is provided at the bottom of the angle clamping plate, and the first moving block 442 is slidably installed in the middle slide groove 431; a pressing component is installed on the outer side of the angle clamping plate, and the pressing component is used to press the four corners of the foam board. The pressing component includes a first adjusting screw and a pressing plate 45, a vertical groove 441 is provided on the side of the angle clamping plate 44, and the pressing plate 45 is horizontally placed in the angle clamping plate 44, and one end of the pressing plate 45 slides through the vertical groove 441, and a first adjusting screw 47 is provided on the outer wall of the angle clamping plate 44, and the first adjusting screw thread penetrates the protruding end of the pressing plate 45.

[0078] In the above scheme: the screw drives the first moving block to move, thereby driving the clamping angle plate to move inward to adapt to the size of the foam board. The pressing plate is initially placed on the top of the clamping angle plate, and the four corners of the foam board are inserted into the clamping angle plate. Then the first adjusting screw rotates to drive the pressing plate to move downward along the vertical groove, and the pressing plate presses down to position the foam board.

[0079] In this embodiment, the ejection assembly 5 includes a moving frame 51, a second moving block 52, a second adjusting screw 53, an ejection tube 56 and an ejection rod 57. The moving frame 51 is slidably mounted on the bottom surface of the inner frame 41. The moving frame 51 is longitudinally distributed. The second moving block 52 is longitudinally slidably mounted inside the moving frame 51.

[0080] In the above scheme: in order to meet the needs of pushing up at different positions, the movable frame can move along the inner frame, and then the second adjusting screw drives the second movable block to move, so that the pushing tube is located below the pushing position; in the narrow mode, the pushing tube is pushed up alone, so that the contact surface is smaller, which can meet the needs of ejecting foam waste of different sizes; in the wide mode, the pushing material assembly needs to push up the foam frame, but it cannot affect the puncture action of the puncture and material collection assembly. Therefore, the second motor is designed to drive the two sets of pushing rods to rotate upward in a V shape, so that the pushing rods extend upward and outward to push the tube, and the pushing rods contact the upper foam frame, and a puncture distance is left between the pushing tube and the foam frame.

[0081] In this embodiment, the piercing and material-collecting component 6 includes a second longitudinal guide rail 61, which is arranged on the side of the crushing and recovery component 8.

[0082] In the above scheme: when the puncture and material collection action is performed, the third longitudinal guide rail moves along the second transverse guide rail, and the puncture and material collection component moves along the third longitudinal guide rail, so that the puncture and material collection component moves to the top of the puncture part; after the puncture is completed, the support plate moves along the second longitudinal guide rail, so that the puncture and material collection component drives the foam plate to move above the crushing and recovery component.

[0083] In this embodiment, the puncture material collection component includes a storage plate 64, a second drive rod 65, a storage tube 66, and a puncture needle 67. The storage plate 64 is slidably installed at the bottom of the third longitudinal guide rail 63. The bottom damping sliding of the storage plate 64 is embedded with a movable plate 641. The bottom end side wall of the movable plate 641 is provided with a horizontal connecting plate 642.

[0085] When the puncture and material collection component 6 is in the puncture mode, it includes the following working steps: S1, the locking plate 68 is first unlocked to separate the puncture needle 67 from the storage tube 66, the second driving rod 65 first drives the needle head of the puncture needle 67 to extend outward, the blocking rod 672 is placed in the storage tube 66, and the locking plate 68 is then inserted into the upper locking groove; S2, the second driving rod 65 drives the storage tube 66 to descend, so that the tip of the puncture needle 67 and the storage tube 66 pierce the foam frame; S3, the locking plate 68 is unlocked, the puncture needle 67 moves downward alone, the blocking rod 672 is separated from the storage tube 66 and gradually rotated upward until the blocking rod 672 is attached to the bottom surface of the foam frame.

[0086] In the above scheme:

[0087] 1. In the plane mode, the locking plate can be moved laterally, and the locking plate can be inserted into the locking groove of the puncture needle, so that the puncture needle and the storage tube are connected as a whole, so that the puncture needle is stably placed in the storage tube as a whole, and when the second driving rod drives the storage tube to move downward, it will drive the storage tube to move downward, so that the flat storage tube can directly press down small-sized foam waste to achieve rapid discharge;

[0088] 2. In the puncture mode, the tip of the puncture needle first extends out of the storage tube to achieve puncture, but the baffle rod cannot be exposed in advance, which will affect the puncture process. Therefore, in the first step, only the tip is exposed; in S2, the tip of the puncture needle and the bottom of the storage tube pass through the foam frame at the same time, and the storage tube maintains the constraint on the baffle rod; in S3, after the storage tube is extended, the baffle rod can be rotated upward, so, therefore, it is unlocked again, and the puncture needle moves downward alone. The torsion spring can drive the baffle rod to rotate automatically upward, and the baffle rod can be extended and stopped at the bottom of the foam frame. In this way, when the puncture needle is lifted, the foam frame can be driven by the baffle rod to move to the top of the crushing and recovery component, and then the puncture needle is completely retracted into the storage tube again, and the foam frame can fall automatically.

[0089] In this embodiment, the composite cooling assembly 24 includes a cooling box 241, which is arranged outside the laser cutting head 23. The internal bottom of the cooling box 241 is a liquid cooling chamber 242, and the internal top is an air cooling chamber 243. The cross-section of the liquid cooling chamber 242 is a U-shaped, one lateral side of the liquid cooling chamber 242 is a liquid inlet portion, and the other lateral side is a liquid outlet portion. The longitudinal sides of the liquid cooling chamber 242 are connecting portions, and multiple groups of cooling baffles 26 are installed at the internal intervals of the connecting portions. The multiple groups of cooling baffles 26 form a serpentine liquid guide channel, and the top seal of each group of cooling baffles 26 extends into the air cooling chamber 243.

[0090] In the above scheme: the lower liquid cooling cavity is designed as the main heat exchange area, and the external liquid storage tank can circulate the coolant; the coolant enters through the liquid inlet, and then enters the liquid outlet through the serpentine liquid guide channel on both sides; the cooling baffle in the serpentine liquid guide channel can export the heat in the liquid cooling cavity to the air cooling cavity. The cooling baffle is designed to be distributed in a serpentine shape, which can increase the contact path between the coolant and the cooling baffle and improve the heat dissipation effect of the coolant.

[0091] In this embodiment, the negative pressure suction assembly 7 includes a suction hood 71, and the side wall of the suction hood 71 is provided with a secondary support arm 72, and the secondary support arm 72 is horizontally slidably installed on the top of the main support arm 73, and the end of the main support arm 73 is rotatably connected to the side plate 74 and a third motor 75 is installed at the rotating connection, and the outlet end of the suction hood 71 is connected to the material guide hose 76.

[0092] In the above scheme: a negative pressure suction component is set to move with the laser cutting head, so that when the laser cutting head is cutting the next position, the suction hood can be placed at the waste material where the previous cutting was completed. In order to meet the needs of attracting waste materials at different positions, the third motor can drive the main support arm to rotate to adjust the suction angle, and the secondary support arm can move along the main support arm to further change the suction hood.

[0093] In this embodiment, a side smoking plate 25 is provided on the bottom side of the cooling box 241, and an air guide mesh 711 is opened on the side of the suction hood 71. A side cover body 712 is installed outside the air guide mesh 711, and an air cooler 77 is installed inside the side cover body 712. A filter pad 78 is installed on the outside of the air cooler 77. The outside of the side cover body 712 is connected in parallel to the air cooling chamber 243 and the side smoking plate 25 through a duct; when the crushing and recovery component 8 is not working, the air cooler 77 is working; when the crushing and recovery component 8 is working, the air cooler 77 is not working.

[0094] In the above scheme: the side smoke extraction plate is provided to directly absorb the smoke in the laser cutting, and then the smoke is led out to the side cover through an independent duct, and the filter pad can absorb and filter the smoke;

[0095] An air guide mesh and an air cooler are set. When the crushing and recovery component is not working, in order to ensure the adsorption of flue gas and cooling of the cooling baffle, the air cooler works independently, and a negative pressure airflow is generated in the air cooling chamber to quickly take away the heat in the air cooling chamber and reduce the temperature of the cooling baffle. When the crushing and recovery component is working, the air cooler does not need to work, and the negative pressure generated by the crushing and recovery component is transmitted to the air cooling chamber and the side smoke exhaust plate through the air guide mesh to reduce energy consumption.

[0096] In this embodiment, the crushing recovery component 8 includes a recovery box 81, and a middle partition 88 is provided inside the recovery box. The top of the middle partition is an upper cavity, and the bottom is a lower cavity. A vertically arranged lower partition 82 is installed inside the lower cavity. A suction fan 84 is installed on one side of the lower partition. The other side of the lower partition is a crushed material storage chamber 811. An extrusion plate 89 is installed inside the crushed material storage chamber. An upper partition 83 is vertically slidably installed inside the lower partition. The relative position between the middle partition and the suction fan is a mesh structure. Through holes are provided at the relative positions of the middle partition and the upper partition, and at the relative positions of the middle partition and the crushed material storage chamber; a horizontally sliding push plate 85 is installed at one end of the interior of the upper cavity, and a crushing tooth roller 86 is installed at the other end of the interior of the upper cavity, and the crushing tooth roller is located above the crushed material storage chamber; an opening for the foam frame to enter is provided at the top of the recovery box, and a sealing plate 87 is horizontally slidably installed on the opening, and a feed pipe 871 is vertically provided on the surface of the sealing plate, and the feed pipe is connected to the material guide hose, and the feed pipe is located above the exhaust fan.

[0097] In the above scheme: when it is necessary to attract waste, the upper partition moves upward into the upper cavity and contacts the sealing plate, so that the upper part of the suction fan is a closed structure to avoid negative pressure dispersion, so that the negative pressure wind force acts accurately on the suction hood;

[0098] After the small-sized foam waste is sucked, the upper partition descends to the side of the lower partition, and then the push plate can be translated along the upper cavity to push the foam waste to the crushing tooth roller, and the crushing tooth roller can rotate to crush the foam waste, and the crushed scraps fall into the scrap storage chamber. The crushing method can increase the storage capacity of the scrap storage chamber, and then the extrusion plate is translated to compress the scraps and further reduce the volume occupied by the scraps;

[0099] When the waste material put in is a foam frame, the sealing plate moves outward to expose the opening, so that the foam frame falls onto the middle partition plate, and the pushing plate pushes it, so that the crushing tooth roller continues to crush the foam frame.
