Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gypsum board production line, in particular to a cutting device for gypsum board edge sealing tape. BACKGROUND

[0002] Gypsum board edge sealing is a key process in the packaging of finished gypsum board products. Its main purpose is to package the end faces of the two sawn gypsum boards to improve the overall appearance of the gypsum board. The stability of the edge sealing will directly affect the appearance quality of the gypsum board. The edge sealing process is mainly carried out by using a roll of edge sealing tape. The inner surface of the edge sealing tape contains self-adhesive, and the outer surface is printed with information such as board type and related parameters. The adhesive inner surface can achieve bonding effect after wet water treatment. The edge sealing tape is pressed onto the surface of the gypsum board by the pressure roller device after passing through the guide device, thereby completing the edge sealing process.

[0003] As shown in Figure 1 and Figure 2 In the related art, the gypsum board edge sealing tape cutting device mainly includes a driving device 1 and a cutter 2 mounted on the driving device 1. In the normal production process, the gypsum board 3 moves forward with the lower transmission structure, the edge sealing tape 6 is pressed onto the gypsum board 3 by the pressure roller 4 after passing through the guide device 5, and is tightly adhered to the surface of the gypsum board 3. There is a gap of 3-5mm between every two gypsum boards 3. When the gypsum board 3 moves to the position where the cutter 2 aligns the gap between the two gypsum boards 3, the driving device 1 extends and drives the cutter 2 to cut off the edge sealing tape.

[0004] However, after the cutter works for a long time and cuts off the edge sealing tape many times, the self-adhesive on the edge sealing tape will accumulate on the cutter. With the passage of time, when the driving device drives the cutter to reset, the accumulated edge sealing tape impurities on the cutter will bring back the cut-off edge sealing tape, resulting in poor edge sealing effect of the end of the gypsum board. In addition, since the cutter needs to be cleaned and maintained frequently, the edge sealing efficiency of the gypsum board is also significantly affected. SUMMARY

[0024] One embodiment of the present application provides a cutting device for gypsum board edge sealing tape, as shown in the drawings, comprising: a cutting assembly and a driving assembly 1; Figure 3 The cutting assembly comprises a cutting knife 2 and a pressing device 100 for the edge sealing tape; the cutting knife 2 and the pressing device 100 are fixedly connected with an output rod of the driving assembly 1, the cutting knife 2 can be accommodated in the pressing device 100, the pressing device 100 is provided with a cutting gap for the cutting knife 2 to enter and exit, and can be telescoped in the movement direction of the cutting knife 2; When cutting, the output rod is extended and drives the cutting assembly, the pressing device 100 first abuts against the edge sealing tape 6 on the side of the gypsum board 3, then the pressing device 100 is compressed, and the cutting knife 2 is extended from the cutting gap to complete the cutting; When resetting, the output rod is retracted and drives the cutting assembly, the pressing device 100 is elongated to reset, the cutting knife 2 is first retracted from the cutting gap, and then the pressing device 100 is separated from the edge sealing tape 6 on the side of the gypsum board 3. The cutting device for gypsum board edge sealing tape provided by the embodiment increases the pressing device 100 in the cutting assembly, and the cutting knife 2 can be accommodated in the pressing device 100 in the elongated reset state of the pressing device 100. When the pressing device 100 is compressed, the cutting knife 2 can be extended from the cutting gap provided on the pressing device 100.

[0025] In this way, when the cutting knife 2 cuts the edge sealing tape 6, the output rod of the driving device 1 drives the cutting assembly to extend forward, so that the pressing device 100 first abuts against the edge sealing tape 6 on the side of the gypsum board 3, then the pressing device 100 is compressed, the cutting knife 2 is extended from the cutting gap on the pressing device 100 to continue to move forward, and the action of cutting off the edge sealing tape 6 is completed.

[0026]

[0027] ​When the cutter 2 is reset, the output rod of the driving device 1 drives the cutting assembly to retract, and the compression device 100 is gradually extended to reset while keeping close to the surface of the edge band 6. In this way, when the cutter 2 is withdrawn from the cutting gap, the edge band 6 can be effectively prevented from being taken back, thereby solving the negative influence of the impurities of the edge band 6 remaining on the cutter 2 on the edge sealing effect of the gypsum board 3 and ensuring the edge sealing quality of the gypsum board. In addition, the scheme provided in the embodiment can reduce the frequency of cleaning and maintenance of the cutter 2, thereby improving the edge sealing efficiency of the gypsum board.

[0030] In the embodiment, the cutter 2 is fixedly connected with the output rod through the hole in the first end plate 9, which can ensure the stability of the cutter 2 during cutting the edge band 6 and resetting.

[0031] In an example embodiment, the elastic element 7 is provided in plurality and symmetrically arranged on both sides of the cutter 2.

[0032] In the embodiment, by symmetrically arranging multiple elastic elements 7 on both sides of the cutter 2, it can ensure that the first end plate 9 and the second end plate 10 are uniformly stressed on both sides during compression and resetting, so that the compression and resetting actions of the compression device 100 are more stable, thereby further improving the cutting quality of the edge band of the gypsum board, and avoiding damage to the device due to uneven stress.

[0033] In an example embodiment, the two ends of the elastic element are fixedly connected with the first end plate and the second end plate by fasteners, respectively.

[0034] In an example embodiment, the elastic element 7 is a spring.

[0035] In an example embodiment, the spring is provided in plurality, and the compression device 100 further comprises a plurality of guide rods 8 corresponding to the plurality of springs, each guide rod 8 passes through a corresponding spring and extends out of the first end plate 9 and the second end plate 10 at both ends, and the two ends of the guide rod 8 limit the first end plate 9 and the second end plate 10, respectively.

[0036] In this embodiment, the guide rod 8 is arranged in the spring correspondingly, and the two ends of the guide rod 8 respectively extend out of the first end plate 9 and the second end plate 10 to limit the first end plate 9 and the second end plate 10 respectively, which can effectively prevent the spring from deviating during compression and resetting, ensure the normal work of the spring, and improve the overall stability of the pressing device 100. In addition, the guide rod 8 can also ensure that the first end plate 9 and the second end plate 10 run more stably during operation, reduce the cutting error caused by shaking, and further improve the cutting quality of the gypsum board edge band.

[0037] In an example embodiment, the initial length of the spring is greater than the length of the cutter.

[0038] In this embodiment, the initial length of the spring is greater than the length of the cutter, so that the cutter 2 can be normally accommodated in the pressing device 100 after the pressing device is elongated and reset.

[0039] In an example embodiment, the width of the cutting gap is greater than the thickness of the cutter 2.
