Description

Technical Field

[0001] The present invention relates to the technical field of laminators, and particularly relates to a laminator with an automatic blanking structure. Background Art

[0002] A laminator is a mechanical device whose main function is to press multiple layers of materials together. This device usually has three or more hot plates, and its function is realized by installing a floating plate between the moving plate and the fixed plate. Laminators are widely used in many fields such as construction, automotive, aerospace, electronics and electrical appliances, and furniture manufacturing. In the construction field, laminators are used to produce decorative boards and sound insulation boards with fire prevention, moisture prevention, heat and other characteristics; in the automotive industry, it is used to produce body panels, door panels, etc., so as to improve the strength and stability of the body structure.

[0003] In the prior art, during the use of a laminator, it is necessary for workers to directly manually load and unload the hot-pressing materials onto the top of the pressing plate, and take out the hot-pressed plates from the top of the corresponding pressing plate to realize the loading and unloading operation of the materials; however, the surface temperature of the hot-pressed plates is relatively high, and when performing manual blanking, it is easy to burn the skin of the workers, and the safety is not high. Therefore, it is necessary to provide a new laminator with an automatic blanking structure to solve the above technical problems. Summary of the Invention

A fixed plate is installed on the front surface of the laminator body. A horizontal plate is arranged on the top of the fixed plate. Two vertical plates are installed on the top of the horizontal plate. A moving frame is arranged between the two vertical plates. Two placing plates are arranged on one side of the moving frame close to the laminator body. The bottom end of the moving frame is rotatably installed with a rotating plate. A blanking mechanism for automatically blanking the processed plates is arranged on the top of the rotating plate.

[0007] Optionally, a rectangular groove is opened at the center position on the top of the fixed plate. A shell is slidably installed inside the rectangular groove. First sliding grooves are opened on both inner walls of the rectangular groove. First sliding blocks are installed inside the two first sliding grooves. One end of the two first sliding blocks away from the first sliding grooves is connected to the shell. A motor is preset inside the shell. The output end of the motor is connected to the horizontal plate.

[0008] Optionally, second sliding grooves are formed in the outer walls of the two vertical plates close to each other, second sliding blocks are installed inside the two second sliding grooves, and one ends of the two second sliding blocks away from the second sliding grooves are connected to the moving frame.

[0009] Optionally, a first groove is formed in the outer wall of the moving frame close to the laminator body, a first double-headed screw is rotatably installed inside the first groove, two first moving blocks are threadedly installed on the outer wall of the first double-headed screw, and one ends of the two first moving blocks away from the first groove are rotatably connected to the placing plates close to them.

[0010] Optionally, a plurality of rollers are rotatably installed on the tops of the two placing plates, and soft pads are detachably installed on the outer walls of the two placing plates close to each other.

[0011] Optionally, third sliding grooves are formed in the outer walls on both sides of the rotating plate, third sliding blocks are installed inside the two third sliding grooves, and one ends of the two third sliding blocks away from the third sliding grooves are rotatably installed with rotating blocks.

[0012] Optionally, electric telescopic rods are installed at the tops of the two rotating blocks, moving rods are installed at the telescopic ends of the two electric telescopic rods, fourth sliding grooves are formed in the outer walls on the sides where the two moving rods are close to each other, and fourth sliding blocks are installed inside the two fourth sliding grooves.

[0013] Optionally, a rectangular strip plate is rotatably installed at the ends of the two fourth sliding blocks away from the fourth sliding grooves, and a plurality of vacuum suction cups are installed on one outer wall of the rectangular strip plate.

[0014] Optionally, a connecting plate is arranged at the top of the rectangular strip plate, a plurality of pressure sensors are installed inside the connecting plate, a second groove is formed inside the rectangular strip plate, a second double-headed screw is rotatably installed inside the second groove, two second moving blocks are threadedly installed on the outer wall of the second double-headed screw, one ends of the two second moving blocks are rotatably installed with connecting rods, and the ends of the two connecting rods away from the second moving blocks are hinged to the bottom end of the connecting plate, and a dust suction head is installed at the end of the connecting plate away from the rectangular strip plate.

[0015] Optionally, a blowing head is installed at the bottom of the rectangular strip plate, and a plurality of air outlet holes are formed at the bottom of the blowing head.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. In this invention, after the laminator body hot-presses the materials placed on the tops of multiple pressing plates into plates, through the mutual cooperation of multiple components of the blanking mechanism, the effect of automatically taking out and blanking the plates formed by hot pressing inside the laminator body can be achieved, without manual taking out, improving the safety of the laminator body for hot pressing the plates into shape, and also improving the efficiency of the laminator body for hot pressing the plates into shape.

[0018] 2. In this invention, when the plate after hot pressing and forming moves to the top of multiple rollers for temporary storage, the rotation and reset of the rectangular strip board can be utilized to bring the air blowing head closer to the plate after hot pressing and forming. With the wind force discharged from multiple air outlets, the plate after hot pressing and forming can be quickly cooled, which is convenient for subsequent other processing of the plate, and thus can indirectly improve the processing efficiency of the plate. Also, by the rotation of the rectangular strip board, the air blowing head can be driven to rotate to a position close to the pressing plate, so that the wind force discharged from multiple air outlets can quickly cool the pressing plate, which is convenient for the subsequent continuous hot pressing and forming of the plate by the pressing plate.

[0019] 3. In this invention, for the plate after cleaning and cooling, the visual inspection equipment preset around the laminating machine body can be used to automatically identify and inspect the appearance of the plate. If the quality of the plate meets the standard, the cross plate can be controlled to rotate 90 degrees clockwise, and the two placing plates can be controlled to move away from each other to the maximum distance, so that the plate can fall downward onto the top of the rotating plate. Then, the two second sliders are controlled to move downward inside the corresponding second chutes, driving the rotating plate to move downward to a specified height together. After that, the rotating plate is controlled to rotate downward to an inclined state at the bottom of the moving frame, so that the plate can slide down onto the top of the preset collection container or the placing platform along the top of the rotating plate. If the quality of the plate does not meet the standard, the cross plate can be controlled to rotate 90 degrees counterclockwise, and the above-mentioned plate blanking steps are repeated, so that the non-standard plate can slide down into the preset other collection container or onto the top of the placing platform, achieving the effect of automatically identifying, inspecting and classifying the blanking of the plate after hot pressing and forming, without the need for workers to transfer the plate into other inspection equipment for inspection and classification, which brings convenience to the subsequent other processing of the plate.

[0020] 4. In this invention, since multiple pressure sensors are installed inside the connecting plate, before the laminating machine body is used, the two rotating blocks can be controlled to drive multiple components such as the two moving rods and the rectangular strip board to rotate downward to a horizontal state. At this time, the rectangular strip board is in a position close to the laminating machine body. The second double-headed screw is controlled to rotate to drive the connecting plate to move between two of the pressing plates. After the laminating machine body is controlled to start, the connecting plate located between two of the pressing plates can detect the pressure when the two pressing plates work, ensuring that the pressure is the same when the laminating machine body simultaneously hot presses and forms multiple plates, so that the laminating machine body can maintain a good hot pressing effect.

[0037] As a technical optimization solution of the present invention, a plurality of rollers 16 are rotatably installed on the tops of the two placing plates 8. Soft pads 17 are detachably installed on the outer walls of the two placing plates 8 close to each other. The two soft pads 17 are detachably connected by magic tapes provided on the outer walls of the two placing plates 8 close to each other, which is convenient for disassembling and replacing the soft pads 17.

[0038] As a technical optimization solution of the present invention, third chutes 37 are formed on the outer walls of both sides of the rotating plate 7. Third sliders 20 are installed inside the two third chutes 37. One end of each of the two third sliders 20 away from the third chutes 37 is rotatably installed with a rotating block 21. Third linear motors are preset inside the two third chutes 37. The two third linear motors can drive the two third sliders 20 to move and adjust inside the corresponding third chutes 37; fourth driving devices are preset inside the two third sliders 20. The output ends of the two fourth driving devices are respectively connected to the rotating parts of the corresponding rotating blocks 21, so as to drive the two rotating blocks 21 to rotate and adjust.

[0039] As a technical optimization solution of the present invention, electric telescopic rods 22 are installed at the tops of the two rotating blocks 21. Moving rods 23 are installed at the telescopic ends of the two electric telescopic rods 22. Fourth chutes 24 are formed on the outer walls of the two moving rods 23 close to each other. Fourth sliders 29 are installed inside the two fourth chutes 24. During the telescopic process of the telescopic ends of the two electric telescopic rods 22, the corresponding moving rods 23 can be driven to move up and down on the tops of the rotating blocks 21; fourth linear motors are preset inside the two fourth chutes 24. The two fourth linear motors can drive the two fourth sliders 29 to move back and forth inside the corresponding fourth chutes 24.

[0040] As a technical optimization solution of the present invention, a rectangular strip plate 25 is rotatably installed at the ends of two fourth sliders 29 away from the fourth chute 24, and a plurality of vacuum suction cups 31 are installed on the outer wall of one side of the rectangular strip plate 25. A fifth driving device is preset inside one of the fourth sliders 29, and the output end of the fifth driving device is connected to the rotating part at one end of the rectangular strip plate 25, so as to drive the rectangular strip plate 25 to rotate and adjust inside the two fourth sliders 29; the plurality of vacuum suction cups 31 are all connected to a preset external vacuum device through corresponding hoses, so that the plurality of vacuum suction cups 31 can be tightly connected to the object to be adsorbed during use.

[0041] As a technical optimization solution of the present invention, a connecting plate 26 is arranged on the top of the rectangular strip plate 25, and a plurality of pressure sensors 30 are installed inside the connecting plate 26. A second groove 33 is opened inside the rectangular strip plate 25, and a second double-headed screw 34 is rotatably installed inside the second groove 33. Two second moving blocks 35 are threadedly installed on the outer wall of the second double-headed screw 34. The tops of the two second moving blocks 35 are rotatably installed with connecting rods 36. One end of the two connecting rods 36 away from the second moving blocks 35 is hinged to the bottom end of the connecting plate 26, and a dust suction head 27 is installed at the end of the connecting plate 26 away from the rectangular strip plate 25. The plurality of pressure sensors 30 are all piezoresistive pressure sensors of model MPX5100 in the prior art; a driving device is preset inside the rectangular strip plate 25, and the output end of the driving device is connected to one end of the second double-headed screw 34, so as to drive the second double-headed screw 34 to rotate and adjust inside the second groove 33; driving the two second moving blocks 35 to move in the direction of approaching or separating from each other. When the two second moving blocks 35 move in the direction of approaching each other, they can drive the two connecting rods 36 to rotate in the direction of approaching each other, and push the connecting plate 26 and the dust suction head 27 to move and adjust in the direction away from the rectangular strip plate 25; when the two second moving blocks 35 move in the direction of separating from each other, they can drive the two connecting rods 36 to rotate in the direction of separating from each other, and pull the connecting plate 26 and the dust suction head 27 to move and adjust in the direction of approaching the rectangular strip plate 25; the dust suction head 27 can be connected to a preset external dust suction device through a first pipe, so that the dust suction head 27 has a dust suction function.

[0042] As a technical optimization solution of the present invention, a blowing head 28 is installed at the bottom of the rectangular strip plate 25, and a plurality of air outlets 32 are opened at the bottom of the blowing head 28. The blowing head 28 can be connected to the output end of a preset external air outlet device through a second pipe, so that the plurality of air outlets 32 can discharge wind outwards.

[0043] In the present invention, when the user uses the device, first control the telescopic ends of the two electric telescopic rods 22 to extend upward together, driving multiple components such as the two moving rods 23 and the rectangular strip plate 25 to move upward and adjust on the tops of the two placing plates 8. Then control the rotation of the first double-headed screw rod 18 to drive the adjustment of the distance between the two first moving blocks 19 and the corresponding placing plates 8, so that the distance between the two placing plates 8 is adapted to the length of the material to be hot-pressed subsequently;

[0044] Then the staff can place the material to be hot-pressed on the tops of the two placing plates 8, so that the material to be hot-pressed is placed on the tops of the multiple rollers 16. Then first control the two third sliders 20 to move in the corresponding third chutes 37 towards the direction close to the moving frame 6 until reaching the ends, and then drive multiple components such as the two moving rods 23 and the rectangular strip plate 25 to move to a position close to the moving frame 6. Then control the telescopic ends of the two electric telescopic rods 22 to contract together, driving multiple components such as the two moving rods 23 and the rectangular strip plate 25 to move downward to reset, and control the two fourth sliders 29 to move downward in the corresponding fourth chutes 24, driving the blowing heads 28 to move downward until they abut against the top ends of the materials placed on the tops of the multiple rollers 16, so as to have the effect of pressing and limiting the stacked multiple materials downward;

[0045] Then control the movement and adjustment of the two second sliders 14 in the corresponding second chutes 13, driving the tops of the multiple rollers 16 to be flush with the top of the second pressing plate 2 from top to bottom inside the laminator body 1, and control the two first sliders 11 to move in the corresponding first chutes 10 towards the direction close to the laminator body 1 until the two placing plates 8 abut against the front surface of the second pressing plate 2. Then, as the two third sliders 20 move in the corresponding third chutes 37 towards the direction close to the laminator body 1, drive the material to be hot-pressed to move on the tops of the multiple rollers 16. With the help of the multiple rollers 16, the moving speed of the material to be hot-pressed can be increased. Until the material to be hot-pressed moves from the tops of the two placing plates 8 to the top of the second pressing plate 2 and is placed, the subsequent other materials to be hot-pressed can repeat the above steps in sequence, placing them on the top of the corresponding pressing plate 2 below, achieving the effect of automatically feeding the materials to be hot-pressed, without manually placing the materials to be hot-pressed on the top of the corresponding pressing plate 2 one by one, reducing the burden on the labor and improving the efficiency of the laminator body 1 for hot-pressing multiple materials.

[0046] After placing the material to be hot-pressed on the tops of the two placement plates 8 as described above, the rectangular strip plate 25 can be controlled to rotate 180 degrees between the two fourth sliders 29, driving the dust suction head 27 to rotate downward to be close to the top of the material to be hot-pressed. As the two fourth sliders 29 move downward inside the corresponding fourth sliding grooves 24, the dust suction head 27 is driven to contact the top end of the material to be hot-pressed. At this time, the two third sliders 20 can be controlled to move back and forth inside the corresponding third sliding grooves 37, and the dust suction head 27 is driven to move back and forth synchronously for adjustment, so that the dust suction head 27 can automatically suck and clean the impurities attached to the top end of the material to be hot-pressed, avoiding the presence of impurities on the top of the material to be hot-pressed and affecting its hot-pressing forming quality;

[0047] After the impurities on the top end of the material to be hot-pressed are cleaned, the two placement plates 8 can be controlled to move a certain distance in the approaching direction, and then the two placement plates 8 are controlled to drive the outer walls of one side of the soft pads 17 to rotate upward by 90 degrees together, so that the two soft pads 17 are both in contact with the bottom end of the material to be hot-pressed. As the first double-headed screw 18 rotates forward and backward, the two placement plates 8 are driven to move back and forth at the bottom end of the material to be hot-pressed together. On the premise of avoiding the two placement plates 8 separating from the bottom end of the material to be hot-pressed, the two soft pads 17 also have the effect of automatically cleaning the bottom end of the material to be hot-pressed, avoiding the presence of impurities at the bottom end of the material to be hot-pressed and affecting its hot-pressing forming quality.

[0048] After the laminator body 1 hot-presses the materials placed on the tops of multiple pressing plates 2 into plates, when the hot-pressed plates need to be taken outwards from the tops of the corresponding pressing plates 2, first control the two rotating blocks 21 to drive multiple components such as the two electric telescopic rods 22 and the moving rod 23 to rotate towards the laminator body 1 and be in an inclined state, and at the same time control the two third sliders 20 to move inside the corresponding third chutes 37 to the end close to the laminator body 1. Then repeat the above relevant steps to make the rollers 16 on the tops of the two placing plates 8 flush with the tops of the corresponding pressing plates 2, and both of the two placing plates 8 are in contact with the fronts of the corresponding pressing plates 2. At this time, the rectangular strip 25 extends into the laminator body 1, and with the elongation of the telescopic ends of the two electric telescopic rods 22, drive the rectangular strip 25 to move deeper inside the laminator body 1 and be above the corresponding pressing plate 2. Control the two rotating blocks 21 to drive the rectangular strip 25 to continue to move downward, and control the rectangular strip 25 to adaptively rotate and adjust between the two fourth sliders 29 so that the rectangular strip 25 itself remains vertical. Until the blowing head 28 at the bottom of the rectangular strip 25 abuts against the top of the plate hot-pressed on the top of the corresponding pressing plate 2, control the two third sliders 20 to move in the corresponding third chutes 37 away from the laminator body 1, and then drive the blowing head 28 abutting against the top of the hot-pressed plate to move outwards on the top of the pressing plate 2, driving the hot-pressed plate to move outwards on the top of the pressing plate 2 to be placed on the tops of the multiple rollers 16, so as to achieve the effect of automatically taking out and discharging the plates hot-pressed inside the laminator body 1, without manual taking-out, and further improving the efficiency of hot-pressing the plates.

[0049] When the hot-pressed plates are temporarily stored on the tops of the multiple rollers 16, the above steps for automatically cleaning the top and bottom of the material to be hot-pressed can be repeated to clean the impurities attached to the top and bottom of the hot-pressed plates again, which is convenient for subsequent stacking and placing of the plates; moreover, the blowing head 28 can be made to approach the hot-pressed plate by the rotational reset of the rectangular strip 25, and the hot-pressed plate can be quickly cooled by the wind discharged from the multiple air outlets 32, which is convenient for subsequent other processing of the plate, and thus can also indirectly improve the processing efficiency of the plate; the blowing head 28 can also be driven to rotate to a position close to the pressing plate 2 by the rotation of the rectangular strip 25, so that the wind discharged from the multiple air outlets 32 can quickly cool the pressing plate 2, which is convenient for the subsequent continuous hot-pressing of the plate by the pressing plate 2.

[0050] After the cleaning and cooling of the board, the visual inspection equipment preset around the laminator body 1 can be used to automatically identify and inspect the appearance of the board. If the quality of the board meets the standard, the cross board 4 can be controlled to rotate clockwise by 90 degrees, and the two placement boards 8 can be controlled to move away from each other to the maximum distance, so that the board falls down onto the top of the rotating board 7. Then, control the two second sliders 14 to move downward inside the corresponding second chutes 13, driving the rotating board 7 to move downward to the specified height. After that, control the rotating board 7 to rotate downward to an inclined state at the bottom of the moving frame 6, so that the board slides down onto the top of the preset collection container or the placement platform along the top of the rotating board 7. If the quality of the board does not meet the standard, the cross board 4 can be controlled to rotate counterclockwise by 90 degrees, and the above-mentioned board blanking steps can be repeated, so that the non-conforming board slides down into the preset other collection container or onto the top of the placement platform, achieving the effect of automatically identifying, inspecting and classifying the blanking of the hot-pressed board, without the need for workers to transfer the board into other inspection equipment for inspection and classification, which brings convenience to the subsequent processing of the board.

[0051] Since a plurality of pressure sensors 30 are installed inside the connecting plate 26, before the laminator body 1 is used, the two rotating blocks 21 can be controlled to drive a plurality of components such as the two moving rods 23 and the rectangular strip plate 25 to rotate downward to a horizontal state. At this time, the rectangular strip plate 25 is in a position close to the laminator body 1. Control the second double-headed screw 34 to rotate and drive the two second moving blocks 35 to move towards each other, and then drive the connecting plate 26 to move away from the rectangular strip plate 25, so that the connecting plate 26 moves between two of the pressing plates 2. When the laminator body 1 is started and the plurality of pressing plates 2 move downward inside the laminator body 1 together, the connecting plate 26 located between two of the pressing plates 2 can detect the pressure when the two pressing plates 2 work. Then, the above steps can be repeated multiple times, so that the connecting plate 26 moves downward to the two pressing plates 2 below in turn, and the pressure when each pressing plate 2 works can be detected, so as to be able to detect whether the pressure when each pressing plate 2 works is the same, ensuring that the pressure is the same when the laminator body 1 hot-presses a plurality of boards at the same time, so that the laminator body 1 can maintain a good hot-pressing effect.

[0052] After the laminator body 1 hot-presses and forms the board, if a small amount of the board adheres to the surface of the platen 2 and cannot be automatically unloaded, in order to avoid adverse effects on the subsequent hot-pressing and forming of the board, when the rectangular strip 25 moves into the laminator body 1 and is located above the board adhering to the surface of the platen 2, first use the air blowing head 28 to accelerate the curing of the board, and then control the side of the rectangular strip 25 with multiple vacuum suction cups 31 to rotate to a position close to the board, control the two fourth sliders 29 to move downward together inside the corresponding fourth chute 24, so that the multiple vacuum suction cups 31 move downward and adsorb and fix the board. As the two fourth sliders 29 move upward together inside the corresponding fourth chute 24, they will drive the rectangular strip 25 and the multiple vacuum suction cups 31 to move upward together, so as to pull the board adhering to the top of the platen 2 until the board is completely pulled and separated from the top of the platen 2. Then, by means of the movement of the two third sliders 20 inside the corresponding third chute 37, drive the rectangular strip 25 and the pulled-down board out of the laminator body 1, achieving the effect of quickly cleaning and unloading the board adhering to the top of the platen 2; if the board adheres to the bottom of the upper platen 2, the position of the multiple vacuum suction cups 31 can be adjusted by the rotation of the rectangular strip 25 so that it can also clean the board adhering to the bottom of the upper platen 2, further improving the applicability of the multiple vacuum suction cups 31.

[0053] At the same time, when the multiple platens 2 are used for a long time, impurities will inevitably adhere to the surface of their working areas. The steps of driving the rectangular strip 25 to move into the laminator body 1 by the relevant components of the above-mentioned unloading mechanism can be repeated, so that the rectangular strip 25 moves between two of the platens 2. Then, by controlling the second double-headed screw 34 to drive the two second moving blocks 35 to move in the approaching direction, the dust suction head 27 on the top of the rectangular strip 25 moves upward to the bottom of the upper platen 2. By means of the reciprocating movement of the two third sliders 20 inside the corresponding third chute 37, the dust suction head 27 works to automatically suck the impurities on the bottom of the upper platen 2; then, by means of the rotation of the rectangular strip 25, drive the dust suction head 27 to rotate downward to contact the top of the lower platen 2 and automatically suck the impurities on the top of the lower platen 2. Repeat the above steps multiple times until the upper and lower sides of the multiple platens 2 inside the laminator body 1 are cleaned, which can facilitate the subsequent use of the laminator body 1.
