TECHNICAL FIELD

[0001] The present application relates to the technical field of gypsum board production, and particularly relates to an edge sealing device and a gypsum board. BACKGROUND

[0002] At present, the edge sealing of gypsum boards is needed to improve the appearance and sales. Since the edge sealing tape is continuous, it needs to be cut by a cutter at a fixed length, and the edge sealing tape has adhesive on one side. During the cutting of the edge sealing tape by the cutter, the adhesive will stick to the cutter, causing the cutter to become thick and blunt. In addition, the stuck edge sealing tape will be stretched during the retraction of the cutter, resulting in poor edge sealing effect. SUMMARY

[0003] The present application provides an edge sealing device and a gypsum board, which can effectively solve the problems of stretching of the edge sealing tape and sticking of the adhesive during the edge sealing process, and improve the edge sealing effect of the gypsum board.

[0004] In one aspect, the present application provides an edge sealing device for cutting an edge sealing tape located at one end of a plurality of gypsum boards, the edge sealing device comprising: a support comprising a plurality of wall portions enclosing a receiving cavity, one of the wall portions being provided with a slit, the receiving cavity being configured to accommodate at least part of the edge sealing tape; and a cutter, a cutter head of the cutter being capable of extending into the slit and cutting the edge sealing tape.

[0005] In one possible implementation, the plurality of wall portions comprises a first wall portion, a second wall portion and a third wall portion, the first wall portion and the second wall portion being oppositely and spacedly arranged, the third wall portion being connected between the first wall portion and the second wall portion, the slit being provided on the third wall portion, and a length direction of the slit being arranged perpendicularly to a length direction of the edge sealing tape.

[0006] In one possible implementation, the edge sealing device further comprises a pressing assembly, the pressing assembly being arranged on a side of at least one of the plurality of wall portions facing the receiving cavity, the pressing assembly being configured to flatten and press the edge sealing tape.

[0007] In one possible implementation, the pressing assembly comprises a plurality of elastic pressing strips, one end of each of the elastic pressing strips being connected to the wall portion, and the other end of each of the elastic pressing strips abutting against the edge sealing tape to flatten and press the edge sealing tape.

[0008] In one possible implementation, along the length direction of the edge sealing tape, the wall portion is sequentially provided with two groups of elastic pressing strips, the slit is correspondingly provided between the two groups of elastic pressing strips, and the two groups of elastic pressing strips are symmetrically arranged relative to the slit, each group of elastic pressing strips comprising at least one elastic pressing strip.

[0009] In one possible implementation, each group of elastic pressing strips comprises at least two elastic pressing strips, the at least two elastic pressing strips being sequentially arranged along the width direction of the edge sealing tape.

[0010] In one possible implementation, the ratio of the slit length to the effective cutting length of the blade and the thickness of the gypsum board is 2:1.8:1.

[0011] In one possible implementation, the edge sealing device also includes a drive unit, the output end of which is connected to the end of the cutter away from the blade head, for driving the blade head to extend into or exit the gap.

[0012] In one possible implementation, the edge banding device also includes a base, with the support fixedly connected to the base.

[0013] On the other hand, this application also provides a gypsum board, one end of which is provided with an edge banding strip, the edge banding strip being cut from an edge banding strip, and the edge banding strip being cut using the edge banding device described above.

[0014] According to the edge banding device and gypsum board provided in this application, a receiving cavity is formed by enclosing multiple walls of the bracket, and one of the walls is provided with a gap. The receiving cavity is used to accommodate at least part of the edge banding strip. The blade of the cutter can extend into the gap and cut the edge banding strip. Since the gap can scrape off the adhesive on the blade of the cutter, the problems of the edge banding strip of the gypsum board opening and the adhesive sticking to the cutter during the edge banding process can be effectively solved, thereby improving the edge banding effect of the gypsum board.

[0024] The technical solutions of the present application will be described clearly and completely below in conjunction with embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Figure 1 A structural schematic diagram of an edge sealing device provided by an embodiment of the present application.

[0026] As shown in Figure 1 , an embodiment of the present application provides an edge sealing device 100 for cutting an edge sealing tape 210 located at one end of a plurality of gypsum boards 200, as shown by the dashed line in Figure 1 , the plurality of gypsum boards 200 are arranged in sequence and in parallel and at intervals, the edge sealing tape 210 is U-shapedly wrapped around one end of the plurality of gypsum boards 200 and is pasted to one end of the plurality of gypsum boards 200 by adhesive, and the edge sealing tape 210 needs to be cut into a plurality of edge sealing tapes 201 by the edge sealing device 100, so that one edge sealing tape 201 is arranged at one end of each gypsum board 200, thereby improving the aesthetic appearance and appearance of the gypsum board 200.

[0027] Specifically, the edge sealing device 100 comprises a support 1 and a cutter 2.

[0028] The support 1 comprises a plurality of wall portions 11 forming an accommodating cavity 10, one of the wall portions 11 is provided with a gap 12, and the accommodating cavity 10 is used to accommodate at least part of the edge sealing tape 210. Adjacent two gypsum boards 200 are arranged at intervals, and at least the interval between the adjacent two gypsum boards 200 corresponds to the part of the edge sealing tape 210 accommodated in the accommodating cavity 10 of the support 1, so as to facilitate cutting off the part of the edge sealing tape 210 by the cutter 2. The edge sealing device 100 can be moved in sequence along the length direction of the edge sealing tape 210 by a preset distance, so that the edge sealing tape 210 can be cut into a plurality of edge sealing tapes 201 in sequence, so that the edge sealing tape 201 is formed at one end of each gypsum board 200, thereby improving the aesthetic appearance and appearance of the gypsum board 200.

[0029] The cutter head 21 of the cutter 2 can extend into the gap 12 and cut the edge sealing tape 210. The gap 12 can scrape the adhesive paste adhered to the cutter head 21 when the cutter head 21 extends into the gap 12 or when the cutter head 21 exits from the gap 12 after cutting the edge sealing tape 210, so as to prevent the cutter 2 from becoming thick and blunt, and to prevent the edge of the edge sealing tape 201 adhered to the gypsum board 200 from being opened, thereby improving the edge sealing effect of the gypsum board 200. Since the manual edge sealing process is omitted, the labor and material costs are greatly reduced.

[0030] Optionally, the cutter head 21 is provided with a plurality of sawtooth-shaped sharp ends, which are relatively sharp and can quickly cut the edge sealing tape 210, thereby improving the cutting efficiency of the edge sealing tape 210.

[0031] It can be understood that when the portions of the edge sealing tape 210 corresponding to the intervals between the plurality of gypsum boards 200 are accommodated in the accommodation cavity 10 of the support 1, the number of the cutter 2 can be one or more. When the plurality of cutters 2 simultaneously cut the edge sealing tape 210, the cutting efficiency of the edge sealing tape 210 can be further improved.

[0032] According to the edge sealing device 100 and the gypsum board 200 provided in the present application, the plurality of wall portions 11 of the support 1 are enclosed to form the accommodation cavity 10, and one of the wall portions 11 is provided with the gap 12. The accommodation cavity 10 is used to accommodate the edge sealing tape 210, and the cutter head 21 of the cutter 2 can extend into the gap 12 and cut the edge sealing tape 210. Since the gap 12 can scrape the adhesive paste adhered to the cutter head 21 of the cutter 2, the problems of the opening of the edge sealing tape 201 of the gypsum board 200 and the adhesive paste of the cutter 2 during the edge sealing process can be effectively solved, and the edge sealing effect of the gypsum board 200 is improved.

[0033] Figure 2 For Figure 1 An assembly structure diagram of the support and the pressing assembly of the edge sealing device is shown.

[0034] In some embodiments, the plurality of wall portions 11 include a first wall portion 111, a second wall portion 112, and a third wall portion 113. The first wall portion 111 and the second wall portion 112 are oppositely and spacedly arranged, and the third wall portion 113 is connected between the first wall portion 111 and the second wall portion 112. The gap 12 is arranged on the third wall portion 113, and the length direction of the gap 12 is arranged perpendicular to the length direction of the edge sealing tape 210.

[0035] As Figure 2As shown, the first wall portion 111, the second wall portion 112 and the third wall portion 113 of the support 1 enclose a U-shaped accommodating cavity 10, the third wall portion 113 is connected between the first wall portion 111 and the second wall portion 112, the gap 12 is arranged on the third wall portion 113, and the length direction of the gap 12 is perpendicular to the length direction of the sealing strip 210. The cutter head 21 of the cutter 2 can extend into the accommodating cavity 10 through the gap 12 of the third wall portion 113, and the sealing strip 210 can be sequentially cut into a plurality of sealing strips 201 along the length direction of the sealing strip 210 by sequentially moving a preset distance along the length direction of the sealing strip 210.

[0036] In some embodiments, the sealing device 100 further comprises a pressing assembly 3 arranged on one side of at least one of the plurality of wall portions 11 facing the accommodating cavity 10, and the pressing assembly 3 is used to flatten and press the sealing strip 210.

[0037] As shown, Figure 2 The pressing assembly 3 is arranged on one side of at least one of the first wall portion 111, the second wall portion 112 and the third wall portion 113 facing the accommodating cavity 10, and the pressing assembly 3 is used to flatten and press the sealing strip 210 to prevent the sealing strip 210 from being raised or generating bubbles due to uneven adhesive paste, thereby further improving the sealing effect of the gypsum board 200.

[0038] In some embodiments, the pressing assembly 3 comprises a plurality of elastic pressing strips 31, one end of the elastic pressing strip 31 is connected to the wall portion 11, and the other end abuts to the sealing strip 210 to flatten and press the sealing strip 210.

[0039] As shown, Figure 2 The plurality of elastic pressing strips 31 are arranged on one side of each of the first wall portion 111, the second wall portion 112 and the third wall portion 113 facing the accommodating cavity 10, and the elastic pressing strip 31 can be a strip-shaped member with a certain elasticity such as a rubber strip or a silica gel strip. One end of the elastic pressing strip 31 is connected to the wall portion 11, and the other end is a free end abutting to the sealing strip 210. The free ends of the plurality of elastic pressing strips 31 can flatten and press the sealing strip 210 by the elastic force of the elastic pressing strips 31.

[0040] In some embodiments, along the length direction of the sealing strip 210, the wall portion 11 is sequentially provided with two groups of elastic pressing strips 31, the gap 12 is correspondingly arranged between the two groups of elastic pressing strips 31, and the two groups of elastic pressing strips 31 are symmetrically arranged relative to the gap 12. Each group of elastic pressing strips 31 comprises at least one elastic pressing strip 31.

[0041] As shown, Figure 2As shown, the first wall portion 111, the second wall portion 112 and the third wall portion 113 are respectively provided with two groups of elastic pressing strips 31, the two groups of elastic pressing strips 31 are sequentially arranged along the length direction of the sealing tape 210, one end of each group of elastic pressing strips 31 is arranged close to the edge of the respective wall portion, and the other end is a free end, so that the two groups of elastic pressing strips 31 are symmetrically arranged relative to the gap 12, so that the sealing tape 210 is flattened and pressed by one group of elastic pressing strips 31 when entering and leaving the accommodating cavity 10, and the sealing effect of each sealing tape 201 can be further improved by flattening and pressing twice.

[0042] In addition, each group of elastic pressing strips 31 includes at least one elastic pressing strip 31, and the gap 12 on the third wall portion 113 is arranged between the two groups of elastic pressing strips 31 to prevent the cutting head 21 from mistakenly cutting the elastic pressing strips 31 when cutting off the sealing tape 210 through the gap 12.

[0043] In some embodiments, each group of elastic pressing strips 31 includes at least two elastic pressing strips 31, and the at least two elastic pressing strips 31 are sequentially arranged along the width direction of the sealing tape 210.

[0044] As an optional implementation, when the width of the sealing tape 210 is large, each group of elastic pressing strips 31 can include at least two elastic pressing strips 31, and the at least two elastic pressing strips 31 are sequentially arranged along the width direction of the sealing tape 210, so as to flatten and press as many positions of the sealing tape 210 as possible, prevent the sealing tape 210 from being raised or generating bubbles due to uneven adhesive paste, and further improve the sealing effect of the gypsum board 200.

[0045] In some embodiments, the ratio of the length of the gap 12 to the effective cutting length of the cutting head 21 and the thickness of the gypsum board 200 is 2:1.8:1.

[0046] As shown in FIG. 1, the cutting head 21 is arranged in the gap 12, and the gap 12 is arranged in the third wall portion 113 of the sealing device 100. Figure 1 As shown, the sealing tape 210 is U-shapedly wrapped around one end of the plurality of gypsum boards 200, and the thickness of the sealing tape 210 is generally thin and can be ignored. In one example, the length of the gap 12 is 20 mm, the effective cutting length of the cutting head 21 is 18 mm, and the thickness of the gypsum board 200 is 10 mm, so that the alignment requirement of the cutting head 21 of the cutter 2 and the gap 12 can be reduced, and the cutting head 21 does not need to be moved up and down to cut off the sealing tape 210 at one end of the gypsum board 200, thereby further improving the cutting efficiency.

[0047] In some embodiments, the sealing device 100 further includes a driving device 4, an output end of the driving device 4 is connected to an end of the cutter 2 away from the cutting head 21, and the driving device 4 is used to drive the cutting head 21 to extend into the gap 12 or exit from the gap 12.

Taking the automatic operation as an example, the driving device 4 can be a telescopic device such as a pneumatic cylinder, a hydraulic cylinder or an electric rod, and the output end of the driving device 4 is connected with the end of the cutting knife 2 away from the knife head 21, for driving the knife head 21 to extend into the gap 12 or exit from the gap 12, and performing the operation of cutting the sealing tape 210.

[0049] In some embodiments, the sealing device 100 further comprises a base (not shown in the figure), and the support 1 is fixedly connected with the base. The base can be a structure fixed to the ground or a supporting platform, and the support 1 fixedly connected with the base can ensure that the support 1 remains stationary relative to the base, while the sealing tape 210 moves in the length direction of the sealing tape 210 by a preset distance in the accommodating cavity 10 of the support 1 in sequence, and the cutting knife 2 synchronously extends into the gap 12 to perform the operation of cutting the sealing tape 210 and then exits from the gap 12, and such a cycle can quickly cut the sealing tape 210 into a plurality of sealing tapes 201.
