[0021] Please refer to Figures 1-10 The present application provides a paper laying machine, comprising a frame 1, a conveying device 2, a paper placing frame 3, a paper taking device 4, a material receiving device 5 and a pushing and shaping device 6.

[0022] The conveying device 2 is arranged on the frame 1, and the conveying device 2 is used for conveying the baking tray 7. In the embodiment, the conveying device 2 adopts the existing conveying belt 20 conveying device 2. Since the conveying belt 20 conveying device 2 is a conveying structure commonly used in the field of mechanical transmission, it is not described here.

[0023] It should be noted that the conveying belt 20 of the conveying device 2 adopts a double-tooth conveying belt. Since the upper surface of the conveying belt 20 on the conveying device 2 is in contact with the baking tray 7, the double-tooth conveying belt can increase the friction between the conveying belt and the baking tray 7, thereby improving the stability of the baking tray 7 during conveying.

[0024] The paper placing frame 3 is arranged on the frame 1, and the paper placing frame 3 is located above the conveying belt 20 of the conveying device 2, so that the paper placing frame 3 and the conveying belt 20 do not interfere with each other. The paper placing frame 3 is used for stacking the baking pad paper 8. In the embodiment, the paper placing frame 3 comprises a support plate 30, and four limit portions 301 are arranged at the positions around the upper surface of the support plate 30. The upper surface of the support plate 30 and the four limit portions 301 form a containing space 302 for containing and limiting the baking pad paper stacked in the vertical direction. That is, it can be understood that the baking pad paper stacked in the vertical direction is placed in the containing space 302 and the baking pad paper is limited in the horizontal direction by the containing space 302, thereby achieving the function of limiting the baking pad paper and avoiding the displacement of the stacked baking pad paper 8.

[0025] The paper placing frame 3 is slidably arranged on the frame 1. Specifically, guide rails 31 are arranged on the opposite sides of the frame 1 in the horizontal Y direction and extend in the horizontal X direction, and the opposite sides of the paper placing frame 3 in the horizontal Y direction are respectively slidably connected with the two guide rails 31. In addition, a driving unit for driving the paper placing frame 3 to slide in the horizontal X direction is arranged on the frame 1. The driving unit can be a linear module or an electric push rod, which is not limited here. As can be seen, when it is necessary to place the stacked baking pad paper in the containing space 302, the paper placing frame 3 can be driven by the driving unit to slide out of the frame 1 in the opposite direction of the conveying belt 20 conveying the baking tray 7, and then the stacked baking pad paper is placed in the containing space 302, thereby facilitating the placement of the baking pad paper.

[0026] In addition, position sensors 310 are arranged at opposite ends of the guide rail 31 and fixed to the rack 1, and the position sensors 310 are controlled by a control system of the paper laying machine. Of course, the above-mentioned driving unit is also controlled by the control system, and the control system can adopt an existing PLC control system. When the paper laying frame 3 moves out of the rack 1 along the guide rail 31 to reach a set position, at this time, the position sensor 310 at the front end of the guide rail 31 feeds back a signal to the control system, and the control system controls the driving unit to stop driving; when the paper laying frame 3 moves into the rack 1 along the guide rail 31 to reach a set position, at this time, the position sensor 310 at the rear end of the guide rail 31 feeds back a signal to the control system, and the control system controls the driving unit to stop driving. In this way, the paper laying frame 3 can be prevented from slipping off the guide rail 31 during the sliding process.

[0027] The paper taking device 4 is arranged on the rack 1 and located above the paper laying frame 3. Specifically, the paper taking device 4 includes a lifting module 40 and a negative pressure suction assembly 41, the lifting module 40 is fixed vertically on the rack 1, the lifting module 40 is drivingly connected with the negative pressure suction assembly 41, and the lifting module 40 is used to drive the negative pressure suction assembly 41 to lift, so that the negative pressure suction assembly 41 can suction the baking pad paper stacked on the paper laying frame 3 one by one.

[0028] The negative pressure suction assembly 41 includes a connecting frame 410 and a plurality of suction nozzles 411, the connecting frame 410 is drivingly connected with the lifting module 40, and a plurality of suction nozzles 411 are arranged around the connecting frame 410. When it is needed to suction the baking pad paper on the paper laying frame 3, the connecting frame 410 is driven by the lifting module 40 to drive the suction nozzles 411 to descend to contact the baking pad paper, and the suction nozzles 411 suction the baking pad paper in a negative pressure mode; after the suction nozzles 411 suction the baking pad paper, the connecting frame 410 is driven by the lifting module 40 to drive the suction nozzles 411 to ascend, so as to drive the suction nozzles 411 to ascend to a preset position with the baking pad paper. The lifting module 40 controls the descending stroke of the negative pressure suction assembly 41, so that the negative pressure suction assembly 41 can suction the baking pad paper stacked on the paper laying frame 3 one by one, and the waste of the baking pad paper caused by suctioning multiple baking pad papers at a time by the suction nozzles 411 can be avoided.

[0029] The material receiving device 5 includes a driving device and a material receiving frame 51, the material receiving frame 51 is slidingly arranged on the rack 1 and has the same sliding direction as the paper laying frame 3. The driving device is arranged on the rack 1 and drivingly connected with the material receiving frame 51, the material receiving frame 51 is provided with a material falling port 510 penetrating through opposite surfaces of the material receiving frame 51, and the driving device drives the material receiving frame 51 to move back and forth between a direction of conveying the baking tray 7 and an opposite direction of conveying the baking tray 7, so that the material receiving frame 51 can be moved to below the negative pressure suction assembly 41 to receive the baking pad paper suctioned by the negative pressure suction assembly 41 or move the baking pad paper received by the material receiving frame 51 to above the baking tray 7.

[0030] The driving device comprises a driving motor 501, slide rails 502, driving wheels 503, driven wheels 504, transmission rods 505 and belts 506. The driving motor 501 is fixed on the rack 1. The slide rails 502 are fixed on the opposite sides of the rack 1 along the horizontal Y direction. The slide rails 502 extend along the horizontal X direction. The material receiving frame 51 is slidably connected with the slide rails 502 through a support frame 508. The transmission rods 505 are rotatably arranged on the rack 1 and extend along the horizontal Y direction. The driving wheels 503 are arranged at the opposite ends of the transmission rods 505. The driven wheels 504 are rotatably arranged on the opposite sides of the rack 1 along the horizontal Y direction. The belts 506 are transmissionally connected between the driving wheels 503 and the driven wheels 504. The belts 506 are connected and fixed with the support frame 508 through connecting pieces 507. Therefore, the driving motor 501 drives the transmission rods 505 to rotate, drives the belts 506 to transmit, and drives the material receiving frame 51 to move back and forth along the slide rails 502 between the direction of conveying the baking tray and the opposite direction of conveying the baking tray 7.

[0031] In addition, a limiting groove 511 is arranged on the upper surface of the material receiving frame 51. The limiting groove 511 and the edge of the material falling port 510 form a positioning step 512. When the material receiving frame 51 moves to the position below the negative pressure adsorption assembly 41, the negative pressure adsorption assembly 41 places the baked pad paper adsorbed thereby in the limiting groove 511. The baked pad paper is limited in the horizontal direction by the positioning step 512, so as to avoid the baked pad paper from being out of position on the material receiving frame 51.

[0032] The rack 1 is provided with a paper laying station. The paper laying station is arranged at the rear end of the paper taking device 4 along the direction of conveying the baking tray and is located directly below the pushing and shaping device 6. The rack 1 is provided with a sensing unit 10. The sensing unit 10 is a sensor. The sensing unit 10 is used for sensing whether the baking tray conveyed on the conveying device 2 is conveyed to the paper laying station. Specifically, a plurality of baking trays are conveyed on the conveying belt 506 of the conveying device 2 from front to back along the horizontal X direction. The paper laying station is arranged at the rear end of the paper taking device 4 along the horizontal X direction. When the baking tray moves to the paper laying station, the sensing unit 10 feeds back a signal to the control system. The driving motor 501 is controlled to stop driving by the control system.

[0033] The pushing and shaping device 6 comprises a lifting pushing assembly and a lifting shaping assembly. The lifting pushing assembly is arranged on the rack 1. The lifting shaping assembly is arranged on the lifting pushing assembly. The lifting pushing assembly is used for pushing the baked pad paper on the material receiving frame 51 from the position of the material falling port 510 to the baking tray while the lifting shaping assembly shapes the baked pad paper pushed into the baking tray. Therefore, when the material receiving frame 51 moves to the position below the lifting shaping assembly, the baked pad paper on the material receiving frame 51 is pushed from the position of the material falling port 510 to the baking tray by the lifting pushing assembly. At the same time, the baked pad paper is shaped in the baking tray by the lifting shaping assembly, so that the baked pad paper is adapted to the shape of the baking tray.

[0034] The lifting and pushing assembly comprises a first lifting unit 601 and a pushing plate 602. The first lifting unit 601 in the embodiment is selected as a lifting cylinder, and in other embodiments, the first lifting unit 601 can also be selected as an electric cylinder, which is not limited here. The first lifting unit 601 is arranged on the rack 1, and the first lifting unit 601 is drivingly connected with the pushing plate 602. The first lifting unit 601 is used to drive the pushing plate 602 to push the baking pad paper on the material receiving frame 51 into the baking tray.

[0035] It should be noted that the bottom surface area of the pushing plate 602 is equal to the bottom surface area in the baking tray. Since the bottom surface area in the baking tray is smaller than the area of the upper end opening of the baking tray, and the area of the baking pad paper is larger than the bottom surface area in the baking tray, the lifting and shaping assembly is designed on the lifting and pushing assembly to shape the baking pad paper in the baking tray. If the lifting and shaping assembly is not designed, the baking pad paper is easily lifted by the pushing plate 602 in the process of the pushing plate 602 rising, thereby causing the paper laying to fail.

[0036] The lifting and shaping assembly comprises four second lifting units 61 and four shaping blocks 62. The second lifting unit 61 in the embodiment is selected as a lifting cylinder, and in other embodiments, the second lifting unit 61 can also be selected as an electric cylinder, which is not limited here. Specifically, the four second lifting units 61 are arranged at the four corner positions on the upper surface of the pushing plate 602. The four corner positions on the upper surface of the pushing plate 602 are provided with accommodating holes 6021 which penetrate through the upper and lower surfaces of the pushing plate 602. The lifting end of each second lifting unit 61 is drivingly connected with each shaping block 62, and each shaping block 62 is located in each accommodating hole 6021. Before the second lifting unit 61 drives the shaping block 62 to descend, the lower surface of the shaping block 62 is flush with the lower surface of the pushing plate 602, so as to avoid the shaping block 62 protruding to the lower surface of the pushing plate 602 and affecting the pushing plate 602 to push the baking pad paper into the baking tray. That is, it can be understood that when the first lifting unit 601 drives the pushing plate 602 to descend into the baking tray to push the baking pad paper on the material receiving frame 51 into the baking tray, the second lifting unit 61 is in a non-extended state, so that the lower surface of the shaping block 62 is flush with the lower surface of the pushing plate 602. At the same time that the pushing plate 602 rises, the second driving unit drives the shaping block 62 to descend, so that each shaping block 62 presses the four corner positions of the baking pad paper against the bottom surface in the baking tray, thereby achieving the shaping effect and avoiding the baking pad paper in the baking tray being lifted by the pushing plate 602 in the process of rising and causing the paper laying to fail. In summary, the lifting shaping block 62 is used in cooperation with the pushing plate 602, so that the baking pad paper enters the baking tray and is shaped in the baking tray into a shape that is adapted to the baking tray.

[0037] The shaped block 62 of the embodiment is made of elastic material, so that the shaped block 62 is in flexible contact with the baking pad paper, avoiding that the shaped block 62 is pressed to break the baking pad paper during shaping the baking pad paper.

[0038] Working principle of the present application: In use, a stack of baking pad papers is placed on the paper placing frame 3, and then the negative pressure adsorption assembly 41 is driven by the lifting module 40 to descend to adsorb the baking pad papers one by one, and then the negative pressure adsorption assembly 41 is driven by the lifting module 40 to ascend. At this time, the material receiving frame 51 is driven by the driving device to move in the opposite direction of the conveying device 2 to move to the lower side of the negative pressure adsorption assembly 41. Then, the baking pad papers adsorbed by the negative pressure adsorption assembly 41 are placed on the material receiving frame 51. Then, the material receiving frame 51 is driven by the driving device to move in the direction of the conveying device 2 to the paper laying station, so that the material receiving frame 51 is located directly above the baking tray stopped on the conveying device 2. At this time, the baking pad papers on the material receiving frame 51 are pushed by the lifting and pushing assembly from the position of the discharging port 510 on the material receiving frame 51 to fall into the baking tray, and at the same time, the baking pad papers falling into the baking tray are shaped in the baking tray by the lifting and shaping assembly, so that the baking pad papers are automatically laid in the baking tray. As can be seen from the above, the baking pad papers are transported and laid and shaped in the baking tray in an automatic manner, replacing the traditional manual laying and shaping of the baking pad papers in the baking tray, greatly improving the paper laying efficiency of the baking pad papers and saving labor.

[0039] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, as described in the specification and drawings of the present application, are also included in the patent protection scope of the present application.
