Description

Technical Field

[0001] The invention relates to the technical field of nursing pad production, in particular to a production device for a double-absorption core for a nursing pad. Background Art

[0002] Nursing pads are disposable sanitary products made of PE film, non-woven fabrics, fluff pulp, polymers and other materials. They are mainly used in hospital surgeries, gynecological examinations, maternal care, child care, paralyzed patients with incontinence, and women during menstruation to absorb body fluids discharged from the human body.

[0003] Nursing pads generally use materials such as kapok or SAP to absorb liquids. Since kapok has a good fluffy effect and SAP material has a high water-locking ability, SAP particles are generally mixed with kapok to form the absorbent core of the nursing pad. There is also a core structure in which SAP particles are attached to the surface of the wood pulp and close to the human body. The structure of SAP close to the human body and the high water absorption capacity of SAP are used to increase the water penetration effect of the nursing pad. However, when processing the core, a nozzle is required to spray the SAP particles onto the surface of the wood pulp. For example, the process of first spraying the SAP particles onto the surface of the wood pulp and then attaching toilet paper to the bottom of the wood pulp requires the wood pulp layer to be transferred and compounded with the toilet paper. During the movement of the wood pulp layer, the SAP particles on it will fall off due to movement, flipping and vibration, resulting in a decrease in the proportion of SAP particles on the wood pulp, affecting the water absorption effect and anti-penetration effect of the nursing pad.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the object of the present invention is to provide a production device for a double-absorbent core for a nursing pad.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a production device for a double-absorbent core for a nursing pad comprises two support plates, each of the ends of the two support plates close to each other is provided with a partition plate, a lower support plate and a lifting assembly are provided between the two support plates and are located below the partition plate, the lifting assembly drives the lower support plate to move up and down, and forms a channel for the sanitary layer to pass through between the lower support plate and the partition plate, the middle of the lower support plate protrudes upward and lifts up the middle position of the sanitary layer, and when the lower support plate is at the uppermost position, the lifted sanitary layer The raw layer is located between the two dividing plates and forms a plane supporting the wood pulp layer with the upper surface of the dividing plates. A particle spraying assembly is arranged between the two supporting plates and is located above the wood pulp layer. The particle spraying assembly is connected to an external cylinder and moves up and down. A plurality of pressure rollers are connected to the lower end of the particle spraying assembly. When the particle spraying assembly is located at the lowermost position, the pressure rollers press the upper surface of the wood pulp layer and make the wood pulp layer and the sanitary layer abut against each other at the middle position. The edge position of the dividing plate close to the middle of the two supporting plates is located between the wood pulp layer and the sanitary layer, and the edge position of the dividing plate close to the middle of the two supporting plates separates the edges of the wood pulp layer and the sanitary layer.

[0007] By adopting the above technical solution, using the structure of the partition plate and the lower support plate, and the structure of forming a channel between the partition plate and the lower support plate, the two ends of the sanitary layer are inserted into the channel, the middle of the sanitary layer is lifted up by the protrusion on the lower support plate to be in the same plane as the upper surface of the partition plate, and then the wood pulp layer is placed on the sanitary layer, wherein the edges of the wood pulp layer and the sanitary layer are separated by the partition plate, and then the particle spraying component is used to spray SAP particles onto the wood pulp layer at the middle position of the wood pulp layer in the device, and the gap on the surface of the wood pulp layer that penetrates into the interior is used to increase the adhesion of the SAP particles to the wood pulp layer The partition plate separates the edge positions of the wood pulp layer and the sanitary layer, so that the SAP particles sprayed out of the wood pulp layer are transferred to the partition plate, which can make the SAP particles in the width direction of the wood pulp layer evenly distributed, and the position where the SAP particles are sprayed out of the edge of the particle spraying component with less SAP particles is sprayed onto the upper surface of the partition plate, further increasing the uniformity of the SAP particles on the wood pulp layer, and before the sanitary layer enters the equipment, glue is applied to the middle position of the sanitary layer, and then the middle position of the wood pulp layer is pressed to the middle position of the sanitary layer by a pressing roller, thereby connecting the wood pulp layer and the sanitary layer as one.

[0008] The present invention is further configured as follows: one end of the two support plates close to each other is fixedly connected with a side plate located below the lower support plate, and the side plates are fixedly connected via a lower collecting plate, the front and rear ends of the side plates are fixedly connected with the lower collecting plate, and an upwardly opening winding chamber is formed between the lower collecting plate, the side plates and the front baffle plate, the dividing plate is fixedly connected at the opening of the winding chamber and close to the inner wall of the support plate, the upper surface of the dividing plate away from the wood pulp layer and close to the support plate is provided with a collecting groove penetrating downward in a direction away from the wood pulp layer, and the side plate is provided with a connecting groove connecting the winding chamber and the collecting groove.

[0009] By adopting the above technical scheme, the structure of the collecting groove and the winding chamber is connected by the connecting groove. After the SAP particles enter the collecting groove, they enter the winding chamber, and then the SAP particles sprayed outside the wood pulp layer are collected in the winding chamber. This not only prevents the SAP particles retained on the dividing plate from affecting the SAP particle content on the subsequent wood pulp layer, but also can collect the scattered SAP particles in the winding chamber for the next use, thereby increasing the utilization rate of the SAP particles.

[0010] The present invention is further configured as follows: the lifting assembly includes a plurality of threaded columns that penetrate the lower collecting plate and are threadedly connected thereto, the upper ends of the threaded columns are rotatably connected to the lower end of the lower supporting plate, and the bottom wall of the winding chamber is fixedly connected to a ring sleeve that encircles the threaded columns.

[0011] By adopting the above technical scheme, a threaded column is used which is threadedly connected to the lower collecting plate. When the threaded column is rotated, the threaded column moves in the vertical direction, and the upper end of the threaded column is rotatably connected to the lower end of the lower supporting plate, that is, the threaded column drives the lower supporting plate to move synchronously in the vertical direction. When the threaded column drives the lower supporting plate to move downward, the space of the channel is increased, and the sanitary layer is then inserted into the channel. The threaded column is then rotated in the opposite direction and drives the lower supporting plate to move upward so that the upper surface of the sanitary layer abuts against the lower surface of the wood pulp layer. The wood pulp layer and the sanitary layer are then driven through the equipment by an external winding and unwinding machine to complete the composite action of the sanitary layer and the wood pulp layer. At the same time, the space size of the channel can be changed according to the thickness of the sanitary layer, thereby increasing the processing range of the equipment. At the same time, the ring sleeve threaded column arranged on the bottom wall of the winding chamber (the upper surface of the lower collecting plate) is separated from the SAP particles in the winding chamber to prevent the SAP particles from affecting the rotation of the threaded column, and also prevents the SAP particles from getting stuck in the thread and being crushed, thereby further increasing the quality of the recovered SAP particles.

[0012] The present invention is further configured such that the length of the sanitary layer in the channel increases first and then decreases from front to back.

[0013] By adopting the above technical scheme, when the wood pulp layer and the sanitary layer enter the equipment, the dividing plate is not stuck between the wood pulp layer and the sanitary layer. As the distance of the wood pulp layer and the sanitary layer entering the equipment increases, the dividing plate is gradually stuck in the sanitary layer and the wood pulp layer and gradually pulled out. When the dividing plate is stuck between the sanitary layer and the wood pulp layer, the particle spraying component sprays SAP particles onto the wood pulp layer, and at the same time, the scattered SAP particles are transferred to the dividing plate to collect the scattered SAP particles. When the dividing plate is not stuck in the sanitary layer and the wood pulp layer, it is convenient for the sanitary layer and the wood pulp layer to enter the equipment for processing, and it is also convenient for the sanitary layer and the wood pulp layer that are composited into one to be removed from the equipment, further increasing the use effect.

[0014] The present invention is further configured as follows: the particle spraying assembly comprises an upper plate arranged between two support plates, a plurality of spray heads are fixedly connected to the lower end of the upper plate, and the spray heads are located directly above the passage at the sanitary layer.

[0015] By adopting the above technical solution, using external jet equipment, SAP particles are sprayed from the nozzle to the upper surface of the wood pulp layer, and then the SAP particles are transferred to the surface of the wood pulp layer, forming a SAP layer on the surface of the wood pulp layer, forming an absorbent core of the SAP layer and the wood pulp layer.

[0016] The present invention is further configured as follows: the particle spraying assembly also includes a limiting fitting, the limiting fitting includes an upper plate arranged between two support plates, a plurality of limiting grooves extending up and down are opened at one end of the support plates close to each other, and a sliding block slidably connected to the limiting groove is fixedly connected to the side wall of the upper plate.

[0017] By adopting the above technical solution, the structure of sliding connection between the slider and the limiting groove is utilized to limit the trajectory of the upper plate moving up and down, thereby ensuring that the nozzle is directly facing the upper surface of the wood pulp layer, and the nozzle is located at the position where the sanitary layer and the wood pulp layer are separated by the dividing plate, thereby ensuring that the SAP particles sprayed by the nozzle outside the wood pulp layer are collected by the collecting groove, and at the same time, the pressure applied by the pressure roller to the surface of the wood pulp layer can be controlled, thereby increasing the composite effect of the sanitary layer and the wood pulp layer.

[0018] The present invention is further configured as follows: a protruding block is fixedly connected to a position of the side plate near the front, two protruding blocks are fixedly connected via a separation block, and the cross section of the separation block is a triangle.

[0019] By adopting the above technical scheme and utilizing the structure of the protruding block, the wood pulp layer enters the equipment from above the protruding block and is located above the dividing plate, and the sanitary layer enters the equipment from below the protruding block and is located below the dividing plate (and is located above the lower supporting plate at the same time), thereby preventing the sanitary layer and the wood pulp layer from contacting and being glued together upon entering the equipment, further increasing the composite effect of the sanitary layer and the wood pulp layer, and making it easier for the lower supporting plate to lift up the sanitary layer and abut against the lower surface of the wood pulp layer.

[0020] The present invention is further configured such that the front end portion of the lower support plate narrows toward the center position of its cross section.

[0021] By adopting the above technical solution and utilizing the structure at the front end of the lower support plate, when the sanitary layer enters the channel and has not reached the pressure roller position, a gap is ensured between the sanitary layer and the wood pulp layer. When at the pressure roller position, the lower support plate lifts up the sanitary layer and abuts against the lower surface of the wood pulp layer to complete the compounding.

[0022] In summary, the present invention has the following beneficial effects: By utilizing the structural setting of the partition plate, the lower support plate and the pressure roller, the sanitary layer with glue is connected and bonded to the lower surface of the wood pulp layer after entering the equipment to complete the compounding, and the bonding position of the two is located in the middle position. Then, the SAP particles are sprayed onto the upper surface of the wood pulp layer by the particle spraying component to form a SAP layer on the wood pulp layer, thereby preventing the SAP particles from detaching from the wood pulp layer and the sanitary layer during the movement of the wood pulp layer, thereby increasing the control effect of the SAP particle content on the wood pulp layer.

[0023] When the particle spraying component sprays SAP particles onto the wood pulp layer, the dividing plate at this position is inserted into the sanitary layer and the wood pulp layer, and the dividing plate and the collecting groove are used to collect the SAP particles at the edge of the spraying range of the particle spraying component. The SAP particles in the collecting groove are then transferred to the winding chamber for collection using the connecting groove part, thereby further increasing the uniformity of the SAP particles on the wood pulp layer and increasing the water absorption effect of the absorbent core.

[0024] Rotate the threaded column and control the up and down movement of the lower support plate to control the space of the channel, thereby adapting to the thickness of the sanitary layer in different types of nursing pads, thereby increasing the processing range of the equipment and increasing the use effect.

[0031] like Figures 1 to 4 As shown, the particle spraying assembly includes an upper plate 26 arranged between the two support plates 11, and a plurality of nozzles 30 are fixedly connected to the lower end of the upper plate 26. The nozzles 30 are located directly above the channel 22 of the sanitary layer 23. The particle spraying assembly also includes a limiting fitting, which includes an upper plate 26 arranged between the two support plates 11, and a plurality of limiting grooves 28 extending up and down are formed at one end of the support plates 11 close to each other, and a slider 27 slidably connected to the limiting groove 28 is fixedly connected to the side wall of the upper plate 26.

[0032] like Figure 1 , Figure 3 and Figure 7 As shown, a protruding block 31 is fixedly connected to the side plate 13 near the front, and the two protruding blocks 31 are fixedly connected by a separation block 32, and the separation block 32 has a triangular cross-section, and the front end portion of the lower support plate 20 narrows toward the center of its cross-section.

[0033] First, use two unwinding machines outside to release the sanitary layer 23 and the wood pulp layer 24 respectively, then use the coating machine to apply glue to the middle position of the upper surface of the sanitary layer 23, and then use the guide roller to introduce the sanitary layer 23 from the front end of the device into the device, and at the same time, make the sanitary layer 23 enter the channel 22 from below the separation block 32, and let the wood pulp layer 24 enter the device from above the separation block 32, and it is located on the upper surface of the dividing plate 14. At this time, the lower support plate 20 is located at the lowest point, that is, the channel 22 has the largest space. When the sanitary layer 23 and the wood pulp layer 24 pass through the device and are wound on the external winding machine, adjust the tension of the sanitary layer 23 and the wood pulp layer 24; The external cylinder is fixedly connected to the connecting column 29 at the upper end of the upper plate 26, and the cylinder is used to drive the connecting column 29 and the upper plate 26 to move up and down. The structure of the sliding block 27 and the limiting groove 28 is used to increase the accuracy of the upper plate 26 moving up and down, thereby controlling the position accuracy of the nozzle 30 and the pressure roller 25 moving downward.
