Description

Technical Field

[0001] This utility model relates to the technical field of hygiene product production equipment, specifically a composite molding equipment for the core of disposable hygiene products. Background Technology

[0002] Common disposable hygiene products include diapers, whose structure includes a core layer that absorbs moisture. The stability of the core layer's quality determines the product's effectiveness. Traditional processing equipment has a relatively long overall length, which means the equipment occupies more space. Utility Model Content

[0003] This invention provides a composite molding equipment for the core of disposable hygiene products, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A composite molding device for the core of a disposable hygiene product includes a transfer mold wheel, a first polymer feeding mechanism, a first composite pressure roller, a conveyor production line, and a second polymer feeding mechanism. The transfer mold wheel is located below the polymer feeding mechanism. The first composite pressure roller cooperates with the transfer mold wheel to extrude and composite the core. A first adhesive spraying mechanism is provided at the front end of the first composite pressure roller. The transfer mold wheel is driven by a mold wheel gear. A conveyor production line is provided at the rear end of the first composite pressure roller. The linear speed of the conveyor production line is consistent with the linear speed of the transfer mold wheel. The second polymer feeding mechanism and a second adhesive spraying mechanism are provided on the conveyor production line. Several first and second polymer feeding mechanisms are provided.

[0006] Compared to traditional processing equipment, the composite molding equipment of this invention has a shorter overall production line length. The transfer mold wheel moves in a circular motion, further reducing the overall length of the production line. The adsorption chamber on the transfer mold wheel generates negative pressure (i.e., vacuum) through a vacuum system (such as a vacuum pump or vacuum generator). Utilizing the pressure difference between atmospheric pressure and the pressure inside the adsorption chamber, the material is adsorbed onto the surface of the mold wheel. When it is necessary to release the material, the vacuum system is shut off, the negative pressure in the adsorption chamber disappears, and the material detaches from the mold wheel under the action of gravity or other external forces. Simultaneously, the transfer mold wheel rotates at a certain angle to achieve the purpose of flipping the product during processing.

[0007] A preferred technical solution: A finished product conveying mechanism is installed at the end of the conveyor production line. This mechanism is a device used to automatically transfer finished products along the production line. It efficiently and accurately transfers finished products from one process to the next, reducing manual intervention and improving production efficiency. It works in conjunction with the conveyor production line to achieve product transport. Examples include: a belt conveyor mechanism, which uses a motor to drive a belt in a cyclical motion, placing products on the belt for transport; and a roller conveyor mechanism, which uses a motor to drive rollers to rotate, utilizing friction to move the products.

[0008] A preferred technical solution: The mold wheel gear is linked to the transmission production line through the steering gear and the synchronizing gear. The steering gear meshes with the mold wheel gear, and the steering gear is linked to the synchronizing gear through the chain.

[0009] A preferred technical solution: The synchronous gear is divided into a first synchronous gear and a second synchronous gear. The first synchronous gear and the second synchronous gear are distributed at the two ends of the transmission production line. The first synchronous gear is linked with the second synchronous gear through a chain.

[0010] A preferred technical solution: A transfer gear is provided between the first synchronous gear and the second synchronous gear.

[0011] A preferred technical solution: The transfer mold wheel is equipped with several adsorption chambers, which are divided and coordinated in different areas. By designing the position and number of adsorption chambers, material deformation or detachment can be avoided.

[0012] A preferred technical solution: three adsorption chambers are provided, namely: a first adsorption chamber, a second adsorption chamber, and a third adsorption chamber.

[0013] A preferred technical solution: Two first polymer feeding mechanisms are set up side by side, and the number of first polymer feeding mechanisms is reasonably set according to requirements. Common polymer feeding mechanisms include a storage bin, a feeding device, a drive system, and a control system. The storage bin is used to store polymer materials, and the feeding device controls the material conveying and metering. Common types include screw feeding, vibratory feeding, and gravity feeding. The drive system can be powered by a motor or pneumatic device. The control system is used to adjust the feeding speed, metering accuracy, and start / stop operation. If manual control is used, the feeding amount is controlled by manually adjusting valves or baffles. If automatic control is used, sensors, PLCs (programmable logic controllers), or computer systems are used to achieve accurate metering and automated operation. The feeding amount is monitored in real time by a weighing sensor, the feeding amount is set according to time, and the feeding amount is controlled by measuring volume (such as screw speed).

[0014] A preferred technical solution: Two second polymer feeding mechanisms are provided and arranged side by side.

[0015] A preferred technical solution: The second synchronous gear is co-centered with another composite pressure roller to cooperate with the finished product conveying mechanism to form a second composite structure. That is, at the end of the conveying production line, another composite structure other than the first composite pressure roller is set, so that the core is compounded and squeezed before being conveyed and packaged by the finished product conveying mechanism, resulting in a higher degree of core fit.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. The composite molding equipment production line in this utility model has a shorter overall length, as the transfer mold wheel moves in a circular motion, thus reducing the overall length of the production line.

[0018] 2. This utility model makes the polymer feeding process more stable by controlling the linear speed of the transmission production line and the finished product conveying mechanism to be consistent with the linear speed of the transfer mold wheel. Attached Figure Description

[0023] like Figure 1As shown, this embodiment provides a composite molding device for the core of disposable sanitary products, including a transfer mold wheel 1, a first polymer feeding mechanism 2, a first composite pressure roller 3, a conveyor production line 4, and a second polymer feeding mechanism 5. The transfer mold wheel 1 is located below the polymer feeding mechanism. The first composite pressure roller 3 cooperates with the transfer mold wheel 1 to extrude and composite the core. A first glue spraying mechanism 6 is provided at the front end of the first composite pressure roller 3. The transfer mold wheel 1 is driven by a mold wheel gear 11. The conveyor production line 4 is provided at the rear end of the first composite pressure roller 3. The linear speed of the conveyor production line 4 is consistent with the linear speed of the transfer mold wheel 1. The second polymer feeding mechanism 5 and the second glue spraying mechanism 13 are provided on the conveyor production line 4. Several first polymer feeding mechanisms 2 and second polymer feeding mechanisms 5 are provided. By keeping the linear speed of the transfer mold wheel 1 and the conveyor production line 4 consistent, the stability of the first polymer feeding mechanism 2 and the second polymer feeding mechanism 5 can be guaranteed when controlling the feeding.

[0024] In existing technologies, the first glue spraying mechanism 6 and the second glue spraying mechanism 13 typically consist of a glue supply system, a spray head, a control system, and a motion system. The glue supply system includes a glue tank, a pump, and a filter. The glue tank stores the glue, and the pump that delivers the glue is commonly a gear pump. The filter prevents impurities from clogging the nozzles. The control system controls the on / off state of the spray head and the glue flow rate according to set parameters. The glue is pumped from the glue tank to the spray head, and the motion system drives the spray head to move along a predetermined path, completing the glue spraying action at the corresponding position.

[0025] Furthermore, a finished product conveying mechanism 7 is installed at the end of the conveyor production line 4. The finished product conveying mechanism 7 is a device used for automatically conveying finished products on the production line. It can efficiently and accurately transfer finished products from one process to the next, reducing manual intervention and improving production efficiency. It can cooperate with the conveyor production line 4 to achieve product transport. For example, a belt conveyor mechanism uses a motor to drive the belt in a cyclical motion, placing the product on the belt for transport; or a roller conveyor mechanism uses a motor to drive the rollers to rotate, using friction to propel the product.

[0026] Furthermore, the mold gear 11 is linked with the transmission production line 4 through the steering gear 8 and the synchronous gear. The steering gear 8 meshes with the mold gear 11, and the steering gear 8 is linked with the synchronous gear through the chain.

[0027] Furthermore, the synchronous gears are divided into a first synchronous gear 9 and a second synchronous gear 10. The first synchronous gear 9 and the second synchronous gear 10 are distributed at the two ends of the transmission production line 4. The first synchronous gear 9 is linked with the second synchronous gear 10 through a chain.

[0028] Furthermore, a transfer gear 12 is provided between the first synchronous gear 9 and the second synchronous gear 10.

[0029] Furthermore, the transfer mold wheel 1 is equipped with several adsorption chambers, which are divided and coordinated in different areas. By designing the position and number of adsorption chambers, material deformation or detachment is avoided.

[0030] Furthermore, three adsorption chambers are provided: a first adsorption chamber 101, a second adsorption chamber 102, and a third adsorption chamber 103.

[0031] Furthermore, two first polymer feeding mechanisms 2 are provided, arranged side by side, and the number of first polymer feeding mechanisms 2 is reasonably set according to the needs.

[0032] Furthermore, two second polymer feeding mechanisms 5 are provided, and they are arranged side by side.

[0033] Furthermore, another composite pressure roller is installed at the same center as the second synchronous gear 10 to cooperate with the finished product conveying mechanism 7 to form a second composite structure. That is, another composite structure other than the first composite pressure roller 3 is set at the end of the transmission production line 4, so that the core is compounded and squeezed before being conveyed and packaged by the finished product conveying mechanism 7, resulting in a higher degree of fit of the core.

[0034] The material (fluffy cotton 100) passes through the transfer mold wheel 1, which is equipped with a first adsorption chamber 101, a second adsorption chamber 102, and a third adsorption chamber 103. Each adsorption chamber generates suction, attracting the polymers sprayed by the first polymer feeding mechanism 2. The polymers are then combined with the material via the first composite pressure roller 3. When the transfer mold wheel 1 transfers the core formed during processing to the conveyor production line 4, the bottom surface of the core faces upwards. The second polymer feeding mechanism 5 continues to spray polymers, which are then combined with another composite pressure roller co-centered with the second synchronous gear 10 via the finished product conveying mechanism 7. The mold wheel gear 11 meshes with the steering gear 8, changing the direction of rotation. The material then passes through the first synchronous gear 9, the transfer gear 12, and the second synchronous gear 10, ensuring that the linear velocity of the transfer mold wheel 1 remains consistent with the linear velocity of the conveyor production line 4 and the finished product conveying mechanism 7. This ensures stable material feeding by the first polymer feeding mechanism 2 and the second polymer feeding mechanism 5.

[0035] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
