s400: the first and second skeleton layers 110 and 210 in the laminated portion 300 are bonded together.

Firstly, a worker prepares a first product 100 to be spliced and a second product 200 to be spliced, wherein the first product 100 to be spliced and the second product 200 to be spliced are two melt-blown fabric products with the same specification under a general condition, the first product 100 to be spliced can comprise a first framework layer 110 and a first material layer 120, and the second product 200 to be spliced can comprise a second framework layer 210 and a second material layer 220; secondly, separating the first framework layer 110 and the first material layer 120 on one side of the first product to be spliced 100, and separating the second framework layer 210 and the second material layer 220 on one side of the second product to be spliced 200; third, the second skeleton layer 210 is inserted and sandwiched between the first skeleton layer 110 and the first material layer 120, and the first material layer 120 is sandwiched between the second material layer 220 and the second skeleton layer 210 to form a 4-layer laminated portion 300; fourth, the first and second skeleton layers 110 and 210 in the overlapping portion 300 are bonded together.

In the whole splicing process, the placing states of the first product to be spliced 100 and the second product to be spliced 200 need to be kept consistent, for example, the first skeleton layer 110 of the first product to be spliced 100 is located below the first material layer 120, and the second skeleton layer 210 of the second product to be spliced 200 is also located below the second material layer 220.

Specifically, by separating the first skeleton layer 110 and the first material layer 120 on one side of the first product 100 to be spliced, separating the second skeleton layer 210 and the second material layer 220 on one side of the second product 200 to be spliced, then clamping the second skeleton layer 210 between the first skeleton layer 110 and the first material layer 120, and clamping the first material layer 120 between the second material layer 220 and the second skeleton layer 210, the integral flatness of the first product 100 to be spliced and the second product 200 to be spliced is good after splicing is completed, and the material layers between the two pieces of meltblown are in contact with each other, so that the use by a user is more convenient.

For example, as shown in fig. 1 to 2, first, a first product 100 to be spliced and a second product 200 to be spliced are placed on a heating device, then the heating device is started to heat the mutually spliced side edges of the first product 100 to be spliced and the second product 200 to be spliced, the heating temperature is between 90 ° and 120 °, when the first product 100 to be spliced and the second product 200 to be spliced are heated to a set temperature, the adhesive between the first framework layer 110 and the first material layer 120 is dissolved, the adhesive between the second framework layer 210 and the second material layer 220 is also dissolved, finally, a worker separates the first framework layer 110 and the first material layer 120 at the splicing position, and simultaneously separates the second framework layer 210 and the second material layer 220 at the splicing position, the worker can also directly and manually separate the first product 100 to be spliced and the second product 200 to be spliced, the separation efficiency can be effectively improved by adopting a heating mode.

In some embodiments of the present invention, the step of separating and forming a certain interval between the first material layer 120 of the heating portion and the first skeleton layer 110, and the step of separating and forming a certain interval between the second material layer 220 of the heating portion and the second skeleton layer 210, comprises the steps of:

s221: rolling the roller 400 on the first material layer 120 of the heating part to enable the first material layer 120 to be adhered to the outer side surface of the roller 400, and turning the roller 400 to be away from the first framework layer 110;

s222: the roller 400 is rolled on the second material layer 220 of the heating part, so that the second material layer 220 is adhered to the outer side surface of the roller 400, and is turned over in a direction away from the second skeleton layer 210 under the driving of the roller 400.

For example, as shown in fig. 2, in the present embodiment, the first product to be spliced 100 and the second material to be spliced are first laid flat on the work table, and the first material layer 120 and the second material layer 220 are faced upward, the drum 400 is then disposed beside a side of the first product to be spliced 100 or a heated portion of the second material to be spliced, the roller 400 is then driven to roll toward the first product to be spliced 100 and the second material to be spliced, during the rolling process, one ends of the first material layer 120 and the second material layer 220 are adhered to the outer side of the drum 400, and is turned in a direction away from the first and second carcass layers 110 and 210 as the drum 400 rolls, and at the same time, the outer side of the drum 400 may be provided with a brush layer or a rubber layer, since the brush layer and the rubber layer have better adhesion to the first material layer 120 and the second material layer 220, the production efficiency is effectively improved.

In some embodiments of the present invention, the bonding the first and second carcass layers 110 and 210 in the laminated portion 300 includes the steps of:

s410: cutting the second material layer 220 in the overlapped portion 300;

s420: the first and second skeleton layers 110 and 210 in the laminated portion 300 are bonded together.

For example, as shown in fig. 3, the overlapping portion 300 includes a 4-layer structure, in which the second material layer 220, the first material layer 120, the second skeleton layer 210 and the first skeleton layer 110 are sequentially arranged, and a worker may directly bond the overlapping portion 300 of the 4-layer structure two by two, or bond the second skeleton layer 210 and the first skeleton layer 110 together, in this embodiment, as shown in fig. 4, after cutting off the second material layer 220 in the overlapping portion 300, then bond the first material layer 120, the second skeleton layer 210 and the first skeleton layer 110 two by two, or only bond the second skeleton layer 210 and the first skeleton layer 110 together, and at this time, the overlapping portion 300 is changed into a 3-layer structure, so that the overall flatness of the spliced material is better, and the quality of the product is improved.

S430: and bonding the first material layer, the first framework layer and the second framework layer together in the laminated part by using an ultrasonic generator.

For example, as shown in fig. 3 and 4, the first material layer 120, the first skeleton layer 110, and the second skeleton layer 210 in the overlapping portion 300 are overlapped together, glue may be firstly coated between the first material layer 120, the first skeleton layer 110, and the second skeleton layer 210, and then the first material layer 120, the first skeleton layer 110, and the second skeleton layer are directly bonded together.

In some embodiments of the invention, the width of the laminating portion 300 is 2-5 mm.

For example, as shown in fig. 3 and 4, the width of the overlapping portion 300 is the width of the overlapping position where the first product to be spliced 100 and the second material to be spliced are overlapped with each other, and in this embodiment, the width of the overlapping portion 300 is 2-5mm, so the width of the heated side of the first product to be spliced 100 and the second product to be spliced 200 is greater than or equal to 2-5 mm.

In some embodiments of the present invention, the bonding the first and second carcass layers 110 and 210 in the laminated portion 300 includes the steps of:

it can be understood that, the first product to be spliced 100 and the second product to be spliced 200 are both meltblown products to be spliced, and in the actual production process, the first product to be spliced 100 and the second product to be spliced 200 can be interchanged with each other.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention. Furthermore, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
