Description

Technical Field

[0001] This invention relates to the field of hygiene product manufacturing equipment technology, and in particular to a core composite molding equipment with polymer and wood pulp and its processing method. Background Technology

[0002] Common disposable hygiene products include diapers, whose structure includes a moisture-absorbing core layer. The stability of the core layer's quality determines the product's effectiveness. A traditional core consists of an upper layer, a middle layer, a lower layer, and a wrapping layer. The middle layer is filled with polymers on both sides, the upper and lower layers are lint-free paper, the middle layer is fluffy cotton, and the wrapping layer is non-woven fabric. Because the shape of the lint-free paper is fixed, its absorbency cannot be controlled by changing its shape. Based on this, the inventor proposed this solution. Summary of the Invention

[0003] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a core composite molding device and processing method with polymer and wood pulp.

[0005] To achieve the above objectives, the technical solution of the present invention is: a core composite molding device with polymer and wood pulp, comprising an intermediate layer conveying mechanism, a first negative pressure mold wheel, an upper layer conveying mechanism, a second negative pressure mold wheel, a third negative pressure mold wheel, a first wrapping layer conveying mechanism, and a second wrapping layer conveying mechanism;

[0006] Both the first negative pressure mold wheel and the second negative pressure mold wheel are equipped with a polymer chamber for storing and releasing polymers. The third negative pressure mold wheel is provided with a wood pulp generating device for releasing wood pulp to form a wood pulp layer. The second negative pressure mold wheel is spaced apart on one side of the third negative pressure mold wheel and is located between the first negative pressure mold wheel and the third negative pressure mold wheel.

[0007] The intermediate layer conveying mechanism is used to guide the intermediate layer to the first negative pressure mold wheel;

[0008] The wrapping layer conveying mechanism is used to convey the wrapping layer to the intermediate layer conveying mechanism and place it under the intermediate layer, so that it enters the first negative pressure mold wheel along with the intermediate layer;

[0009] The upper layer conveying mechanism is used to guide the upper layer to the first negative pressure molding wheel and attach it to the surface of the middle layer. During the process of transferring the upper layer to the first negative pressure molding wheel, the upper layer is sprayed with glue by the upper layer glue spraying mechanism and then adhered to the surface of the middle layer by the upper layer pressing roller.

[0010] The first negative pressure mold wheel is used to adsorb the polymer released from the polymer chamber onto one side of the intermediate layer and then transfer the intermediate layer to the second negative pressure mold wheel by rotating itself.

[0011] The second negative pressure molding wheel is used to adsorb the polymer released from the polymer chamber onto the other side of the intermediate layer and transfer the intermediate layer between the second negative pressure molding wheel and the third negative pressure molding wheel;

[0012] The third negative pressure molding wheel is used to adsorb the wood pulp released by the wood pulp generating device onto the coating layer to form a wood pulp layer and to transfer the coating layer between the second negative pressure molding wheel and the third negative pressure molding wheel;

[0013] The second coating layer conveying mechanism is used to separate the coating layer from the intermediate layer and transfer it to the third negative pressure mold wheel during the process of transferring the coating layer from the first negative pressure mold wheel to the second negative pressure mold wheel. During the process of transferring the coating layer to the third negative pressure mold wheel, the coating layer is sprayed with glue on its surface by the first coating layer glue spraying mechanism. A wood pulp layer glue spraying mechanism for spraying glue on the surface of the wood pulp layer is provided above the third negative pressure mold wheel.

[0014] The rear ends of the second negative pressure mold wheel and the third negative pressure mold wheel are provided with a wrapping mechanism. The core moves from the second negative pressure mold wheel to the wrapping mechanism through the intermediate pressure roller and the embossing roller. During the transfer of the wrapping layer, adhesive is sprayed on its surface by the wrapping layer spraying mechanism two, and the core is wrapped and shaped by the wrapping mechanism.

[0015] Preferably, it further includes a lower layer conveying mechanism for transporting the lower layer. The lower layer conveying mechanism guides the lower layer to the third negative pressure mold wheel. The lower layer is transferred to the second negative pressure mold wheel via the third negative pressure mold wheel. During the transfer to the third negative pressure mold wheel, the lower layer is sprayed with glue on its surface by a wood pulp layer glue spraying mechanism, and the lower layer is adhered to the surface of the intermediate layer by an intermediate pressure roller. The wrapping layer is adhered to the lower layer by a lower layer pressing roller. The lower layer conveying mechanism includes a lower layer transmission mechanism and a lower layer correction mechanism. The lower layer correction mechanism is located at the rear end of the lower layer transmission mechanism.

[0016] Preferably, the intermediate layer conveying mechanism includes an intermediate layer transmission mechanism and an intermediate layer correction mechanism, wherein the intermediate layer correction mechanism is located at the rear end of the intermediate layer transmission mechanism.

[0017] Preferably, the upper conveying mechanism includes an upper transmission mechanism and an upper correction mechanism, wherein the upper correction mechanism is located at the rear end of the upper transmission mechanism.

[0018] Preferably, the wrapping layer conveying mechanism includes a wrapping layer transmission mechanism.

[0019] Preferably, the second wrapping layer conveying mechanism includes a second wrapping layer transmission mechanism and a second wrapping layer correction mechanism, wherein the second wrapping layer correction mechanism is located at the rear end of the second wrapping layer transmission mechanism.

[0020] Preferably, the second wrapping layer conveying mechanism further includes several guide rollers, and the wrapping layer is guided from between the first negative pressure mold wheel and the second negative pressure mold wheel to the second wrapping layer transmission mechanism by several of the guide rollers.

[0021] Preferably, the wood pulp generating device is connected to a polymer silo.

[0022] A method for processing a wood pulp polymer composite core includes the following processes.

[0023] S1: Guide the intermediate layer to the first negative pressure mold wheel through the intermediate layer conveying mechanism;

[0024] S2: The wrapping layer is guided to the intermediate layer conveying mechanism and placed under the intermediate layer, and enters the first negative pressure mold wheel together with the intermediate layer;

[0025] S3: The polymer chamber releases polymers, and the negative pressure generated by the first negative pressure mold wheel causes the polymers to be adsorbed onto the intermediate layer;

[0026] S4: The upper layer is transferred to the first negative pressure mold roller through the upper layer conveying mechanism and attached to the upper layer. During the transfer process, glue is applied through the upper layer spraying mechanism, and then the upper layer is laminated with the middle layer through the upper layer pressing roller.

[0027] S5: After the intermediate layer is laminated with the upper layer, it is transferred from the first negative pressure molding wheel to the second negative pressure molding wheel. During the transfer, the intermediate layer flips over as the first negative pressure molding wheel rotates. At this time, the wrapping layer is transferred to the top of the intermediate layer. When the intermediate layer enters the second negative pressure molding wheel, the wrapping layer conveying mechanism 2 drives the wrapping layer to separate from the intermediate layer and transfer it into the third negative pressure molding wheel. During the transfer of the wrapping layer to the third negative pressure molding wheel, the wrapping layer is glued by the wrapping layer glue spraying mechanism 1.

[0028] S6: The polymer chamber above the second negative pressure mold wheel releases polymers, which are adsorbed onto the intermediate layer under the negative pressure of the second negative pressure mold wheel;

[0029] S7: The intermediate layer with polymer on both sides and the coating layer with wood pulp layer are driven by the second negative pressure mold wheel and the third negative pressure mold wheel to enter between the second negative pressure mold wheel and the third negative pressure mold wheel for extrusion and bonding. The wood pulp layer is extruded to the required thickness in this process. Before entering between the second negative pressure mold wheel and the third negative pressure mold wheel, the wood pulp layer will be sprayed with glue by the wood pulp layer spraying mechanism.

[0030] S8: After completing the polymer filling on both sides of the intermediate layer, the composite of the upper layer and the intermediate layer, the composite of the wood pulp layer and the intermediate layer, and the composite of the wood pulp layer and the wrapping layer, the core semi-finished product is transferred to the wrapping mechanism by the power of the intermediate pressure roller and the embossing roller. During the transfer process, the wrapping layer is glued by the second glue spraying mechanism. The wrapping mechanism covers the two sides of the wrapping layer on both sides of the core and is also composited on the upper layer.

[0031] S9: After the core is pressed again, the core is formed and sent out of the forming device.

[0032] A method for processing a polymer composite core includes the following processes.

[0033] S1: Guide the intermediate layer to the first negative pressure mold wheel through the intermediate layer conveying mechanism;

[0034] S2: The wrapping layer is guided to the intermediate layer conveying mechanism and placed under the intermediate layer, and enters the first negative pressure mold wheel together with the intermediate layer;

[0035] S3: The polymer chamber releases polymers, and the negative pressure generated by the first negative pressure mold wheel causes the polymers to be adsorbed onto the intermediate layer;

[0036] S4: The upper layer is transferred to the first negative pressure mold roller through the upper layer conveying mechanism and attached to the upper layer. During the transfer process, glue is applied through the upper layer spraying mechanism, and then the upper layer is laminated with the middle layer through the upper layer pressing roller.

[0037] S5: After the intermediate layer is laminated with the upper layer, it is transferred from the first negative pressure molding wheel to the second negative pressure molding wheel. During the transfer, the intermediate layer flips over as the first negative pressure molding wheel rotates. At this time, the wrapping layer is transferred to the top of the intermediate layer. When the intermediate layer enters the second negative pressure molding wheel, the wrapping layer conveying mechanism 2 drives the wrapping layer to separate from the intermediate layer and transfer it into the third negative pressure molding wheel. During the transfer of the wrapping layer to the third negative pressure molding wheel, the wrapping layer is glued by the wrapping layer glue spraying mechanism 1.

[0038] S6: The polymer chamber above the second negative pressure mold wheel releases polymers, which are adsorbed onto the intermediate layer under the negative pressure of the second negative pressure mold wheel;

[0039] S7: The lower layer is transferred to the third negative pressure mold wheel through the lower layer conveying mechanism. The coating layer after being glued by the coating layer spraying mechanism is placed under the lower layer. It is then bonded to the lower layer by the lower layer pressing roller. The coating layer and the lower layer are transferred to the second negative pressure mold wheel through the third negative pressure mold wheel. During the transfer, the wood pulp layer spraying mechanism applies glue, and then the middle pressure roller is used to bond it to the upper part of the middle layer.

[0040] S8: After completing the polymer filling on both sides of the intermediate layer, the lamination of the upper and lower layers with the intermediate layer, and the lamination of the lower layer with the wrapping layer, the core semi-finished product is transferred to the wrapping mechanism by the power of the intermediate pressure roller and the embossing roller. During the transfer process, the wrapping layer is glued by the second glue spraying mechanism. The wrapping mechanism covers the two sides of the wrapping layer on both sides of the core and is also laminated on the upper layer.

[0041] S9: After the core is pressed again, the core is formed and sent out of the forming device.

[0042] In summary, the beneficial effects of this invention are:

[0043] 1. By using a third die wheel and a wood pulp generation device, one layer of dust-free paper is replaced by a wood pulp layer. By controlling the phase of the third negative pressure die wheel, the shape of the wood pulp on the wrapping layer can be controlled, such as where to leave gaps or where to increase or decrease the thickness, thereby controlling the water-conducting performance and allowing for customization according to needs.

[0044] 2. By adding a lower conveying mechanism, the equipment can simultaneously generate two types of cores: a traditional polymer composite core and a wood pulp polymer composite core. When the lower conveying mechanism is closed and the wood pulp generating device is activated, it produces a wood pulp polymer composite core; when the lower conveying mechanism is activated and the wood pulp generating device is closed, it produces a polymer composite core.

[0045] 3. This invention optimizes the conveying process of the coating layer. The coating layer is first conveyed to the bottom of the intermediate layer. As the intermediate layer enters the first negative pressure mold wheel, the bonding between the upper layer and the intermediate layer is not affected. When the intermediate layer flips over as the first negative pressure mold wheel rotates, the coating layer is transferred to the top of the intermediate layer. At this time, the two sides of the intermediate layer are respectively bonded by the coating layer and the upper layer. In this way, it is difficult for the polymer to come out of the intermediate layer, thus ensuring the retention of the polymer while ensuring the conveying speed on the line.
