Description

Technical Field

[0001] The utility model relates to the technical field of bed net production machinery, in particular to a surface cloth cutting mechanism. Background Art

[0002] Mattress is a commonly used furniture, generally composed of bed net and outer packaging.

[0003] The existing bed net production is generally made by welding or gluing multiple spring strips. When producing the bed net, a piece of cover cloth needs to be fixed on the top and / or bottom of the bed net. The existing production technology generally glues a continuous cover cloth on the top and / or bottom of the bed net during the welding / gluing process of the bed net, and the size of the cover cloth is larger than the size of the bed net, so the cover cloth needs to be cut after the production is completed to separate the finished products.

[0004] The existing cutting device directly sets a cutter that can cyclically move. When the face cloth between two bed nets passes the cutter, the cutter cuts through the face cloth between the two bed nets, thus completing the face cloth cutting process. However, in actual production, since the size of the face cloth is much larger than the size of the bed net, at this time, for some high-height bed nets, the two sides of the face cloth at the top of the bed net will naturally sag, and when tensioned by the tensioning roller, it is impossible to ensure that the two sides of the face cloth are tensioned. At this time, it is easy to cause the cutter to align with the two sides of the face cloth, resulting in the situation that the two sides are not cut off during cutting. Utility Model Content

[0031] The cutting device 1 comprises a first cutting blade assembly 11 and a displacement mechanism 12, wherein the displacement mechanism 12 is used to drive the first cutting blade assembly 11 to move back and forth along a first direction;

[0032] The cloth lifting mechanism 2 comprises a cloth lifting plate 21 and a cloth lifting driving mechanism 22. The cloth lifting plate 21 is disposed on at least one side of both sides of the first cutting knife group 11. The cloth lifting driving mechanism 22 is used to drive the cloth lifting plate 21 to move back and forth along the third direction.

[0033] It should be noted that if Figures 1 to 8 As shown, the first direction is the left-right direction, the second direction is the up-down direction, and the third direction is the front-back direction.

[0034] It should be noted that, as shown in the figure, a cloth lifting plate 21 is provided on both sides of the first cutting knife group 11, and four cloth lifting plates 21 are arranged in groups of two on the left and right sides, and the two groups of cloth lifting plates 21 are arranged opposite to each other.

[0035] It should be noted that the surface fabric 102 may be non-woven fabric, woven fabric, or other textile fabrics.

[0036] It should be noted that in order to make people further understand the specific role of the utility model, such as Figures 4 to 6 The figure shows one specific use of the present invention, with a bed net 101 and a surface cloth 102. When the present invention is in use, the cloth lifting drive mechanism 22 drives the cloth lifting plate 21 to lift so that the two ends of the surface cloth 102 are directly opposite to the blade of the first cutting knife group 11 (such as Figure 5As shown), the displacement mechanism 12 drives the first cutting knife group 11 to move left and right so that the blade of the first cutting knife group 11 passes through the face cloth 102, thus completing the cutting process of the face cloth 102 (as shown in FIG. Figure 6 Then, the cloth lifting driving mechanism 22 drives the cloth lifting plate 21 to descend and reset, waiting for the next cutting process (as shown in FIG. Figure 4 shown).

[0037] The utility model has the advantages that a cloth lifting plate for lifting the side of the surface cloth is arranged on the side of the cutter, so that the cloth lifting plate lifts the surface cloth to the blade of the cutting knife group before each cutting, effectively avoiding the problem that the blade of the cutting knife group cannot cut the surface cloth due to the natural sagging of the two sides of the surface cloth.

[0038] More specifically, the two sets of cloth lifting mechanisms are arranged opposite to each other along the first direction.

[0039] Furthermore, at least one cloth lifting plate 21 is respectively disposed on both sides of the first cutting knife group 11, and the cloth lifting driving mechanism drives all the cloth lifting plates 21 to move back and forth along the third direction independently or synchronously.

[0040] Specifically, as shown in one embodiment of the utility model, in this embodiment, a cloth lifting plate 21 is provided on both sides of the first cutting knife group 11, so that when the two cloth lifting plates 21 lift the supporting surface cloth 102, the blade of the first cutting knife group 11 located between the two cloth lifting plates 21 can be accurately aligned with the surface cloth 102, which is beneficial to the subsequent cutting of the first cutting knife group 11.

[0041] More specifically, Figures 1 to 3 The figure shows one embodiment of the utility model. In this embodiment, the cloth lifting driving mechanism 22 corresponds to the cloth lifting plates 21 one by one, so that the cloth lifting driving mechanism 22 can drive the synchronous or independent displacement of all the cloth lifting plates 21.

[0042] Furthermore, the cloth lifting driving mechanism 22 is a cylinder.

[0043] More specifically, the cylinder has the advantages of fast displacement speed and stable distance, which is beneficial to the back and forth displacement of the cloth lifting plate 21 in the third direction.

[0044] It should be noted that the cloth lifting driving mechanism 22 only needs to drive all the cloth lifting plates 21 to move synchronously or independently.

[0045] Furthermore, the first cutting knife set 21 includes two cutting knives which are arranged obliquely along the third direction and whose blades are opposite to each other, and the two cutting knives are scissor-shaped when matched.

[0046] More specifically, by providing a scissor-shaped cutter, the face cloth is cut by the scissor-shaped first cutter group 21 , and the scissor-shaped cutter is conducive to the rapid cutting of the face cloth 102 .

[0047] Furthermore, the first cutting knife group 21 is composed of four cutting knives, and the four cutting knives are combined to form an "X" shape.

[0048] More specifically, by arranging four cutters in an X shape, two groups of cutters in a scissor-shaped arrangement are provided on both sides of the first cutter group 21, so that the first cutter group can use the scissor-shaped cutters to cut the fabric 102 when it moves back and forth along the first direction.

[0049] Furthermore, the cutting device 1 group also includes a second cutting knife group 13 and a supporting plate 14, a through slot 15 is provided in the middle of the supporting plate 14, and the cutting knife of the second cutting knife group 13 passes through the through slot 15 in the middle of the supporting plate 14, and the displacement mechanism 12 is used to drive the first cutting knife group 11 and the second cutting knife group 13 to move back and forth along the first direction synchronously or independently.

[0050] Furthermore, the distance between the first cutting knife set 11 and the second cutting knife set 13 is adjustable.

[0051] Furthermore, it also includes a bonding conveyor belt 3 and an output mechanism 4, and the cutting device 1 is arranged between the bonding conveyor belt 3 and the output mechanism 4.

[0052] More specifically, the cutting device 1 is disposed between the adhesive conveyor belt 3 and the output mechanism 4, so as to ensure that the cutting device can cut off the surface cloth 102 between the adhesive conveyor belt 3 and the output mechanism 4.

[0053] Furthermore, the conveying speeds of the bonding conveyor belt 3 and the output mechanism 4 can be adjusted independently.

[0054] More specifically, by bonding the conveying speed difference between the conveying belt 3 and the output mechanism 4, the surface cloth 102 can be placed in a tensioned state, which is convenient for cutting.

[0055] In summary, the advantages of the utility model are: 1. A cloth lifting mechanism is provided, through which the naturally drooping side of the surface cloth is lifted, so that the side of the surface cloth faces the blade of the first cutting knife group, thereby avoiding the situation where the surface cloth is unable to be cut due to the drooping of the cutter; 2. Cloth lifting plates are provided on both sides of the first cutting knife group, which is beneficial for the first cutting knife group to cut the surface cloth; 3. The two groups of cloth lifting mechanisms are relatively separated, ensuring that both sides of the surface cloth can be lifted, which is further beneficial for the first cutting knife group to cut the surface cloth.

[0056] For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and concepts described above, and all of these changes and modifications should fall within the protection scope of the claims of the utility model.
