Description

Technical Field

[0001] The present invention relates to the technical field of sanitary napkin hot pressing, and more specifically, to a hot stamping device for rare earth composite antibacterial sanitary napkins. Background Art

[0002] A rare earth composite antibacterial sanitary napkin is a product that combines rare earth elements with other antibacterial materials and adds them to the materials of the sanitary napkin. By virtue of its antibacterial properties, it can improve the sanitary performance and user experience of the sanitary napkin. As a metal element with special properties, rare earth elements are usually used to improve the antibacterial property, antioxidant property of materials and extend the service life of products. During the use of sanitary napkins, unpleasant odors are likely to be generated due to bacterial growth. The antibacterial effect of rare earth composite materials helps to reduce the growth of these bacteria, thus delaying the generation of odors. During the production of rare earth composite antibacterial sanitary napkins, materials such as water-absorbing cores and non-woven fabrics need to be firmly bonded together through hot pressing to form a stable overall structure.

[0003] When the existing sanitary napkin hot pressing device presses the raw materials, it usually designs symmetric pressing rollers to hot press the materials in transmission. Since the raw materials are continuously transported forward, the raw materials are prone to slip between the hot pressing bars, affecting the hot pressing quality. Summary of the Invention

[0015] The beneficial effects of a hot stamping device for rare earth composite antibacterial sanitary napkins provided by the present invention include: 1. By providing a hot pressing mechanism, the first motor drives the turntables on the upper and lower sides to rotate at the same speed in opposite directions to hot press the sanitary napkins. The pressing die is pushed by extrusion to move towards the inner cavity of the turntable, sucking the air collecting cavity on the side of the first limiting ring, and inhaling air through the first air passage into the negative pressure holes, adsorbing the sanitary napkin material on the surface of the pressing die, avoiding slippage of the sanitary napkin material with the first hot pressing strip and the second hot pressing strip, and ensuring the hot pressing quality; when the hot pressing is completed and the two pressing dies are separated from each other, the first spring pushes the first piston to reset, spraying the air in the air collecting cavity out of the negative pressure holes again to dissipate heat from the hot-pressed sanitary napkin, and at the same time, blowing the sanitary napkin away from the first hot pressing strip and the second hot pressing strip to avoid adhesion of the sanitary napkin to the first hot pressing strip and the second hot pressing strip.

[0016] 2. By setting up the bristle mechanism, the second motor drives the sleeve shaft and the second rotating shaft to rotate through gears, so as to brush the surface of the material through the bristle roller. When the second rotating shaft rotates, it drives the arc-shaped driving ring to rotate synchronously, and under the action of the second spring, it drives the second rotating shaft to swing left and right in the inner cavity of the sleeve shaft, driving the bristle roller to move synchronously, improving the brushing effect. In addition, when the upper and lower pressing dies contact to perform hot pressing on the sanitary napkin, the pressing die is extruded and moves towards the inner cavity of the turntable, injecting the air in the air collecting cavity into the hollow part of the first rotating shaft, and sending it into the hollow part of the bristle roller through the second rotary joint and the first rotary joint, and finally spraying it out from the spray holes onto the surface of the material, improving the fluffiness of the material, making the heat distribution more uniform during the hot pressing process, and improving the bonding effect.

[0017] 3. By setting up the feeding mechanism, whenever the upper and lower pressing dies contact, the first rotating shaft drives the third rotating shaft to rotate one circle through the pulley, making the third through hole communicate with the driving groove, so as to inject air into the driving groove through the air pump. And because the aperture of the third through hole is larger than that of the air hole, part of the air flow pushes the second connecting rod downward, separating the sanitary napkin from the material through the push block for feeding, and the other part of the air flow sprays out onto the surface of the sanitary napkin through the air hole to perform secondary heat dissipation on the sanitary napkin, ensuring the quality of the sanitary napkin.

Specific embodiments

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figures 1 - 10As shown in the figure, the present invention provides a technical solution: a hot stamping device for rare earth composite antibacterial sanitary napkins, which includes a machine table 1 and guide rollers 3. On the side wall of the machine table 1, raw material rollers 2 are symmetrically and rotatably installed for placing the raw materials of sanitary napkins. On the side wall of the machine table 1, a number of guide rollers 3 are symmetrically and rotatably installed for guiding the raw materials. A hot pressing mechanism 4 is installed on the surface of the machine table 1. The hot pressing mechanism 4 includes a turntable 401, a first connecting rod 407 and an air collecting chamber 409. The turntable 401 is symmetrically and rotatably installed on the side wall of the machine table 1. A first rotating shaft 402 is fixedly installed in the inner cavity of the turntable 401. The turntable 401 is rotationally connected to the machine table 1 through the first rotating shaft 402. The upper and lower turntables 401 rotate in opposite directions at the same speed. In the inner cavity of the turntable 401, pressing dies 403 are symmetrically and slidably installed. On the surface of the pressing die 403, a first hot pressing strip 404 and a second hot pressing strip 405 are installed for hot pressing the sanitary napkin. A cutting knife 406 is fixedly installed on the surface of the pressing die 403 for cutting the sanitary napkin.

[0022] Referring to Figures 1 - 5 As shown in the figure, in a preferred embodiment, the first connecting rods 407 are symmetrically and fixedly installed at the bottom of the pressing dies 403. The first connecting rods 407 are slidably connected to the turntable 401. A first spring 408 is sleeved on the surface of the first connecting rod 407 for driving the pressing die 403 to move towards the outside of the turntable 401. The air collecting chamber 409 is opened in the inner cavity of the turntable 401. A first piston 410 is slidably installed in the air collecting chamber 409. The first piston 410 is fixedly connected to one end of the first connecting rod 407. When the upper and lower pressing dies 403 come into contact to hot press the sanitary napkin, the pressing die 403 is extruded and moves towards the inner cavity of the turntable 401, driving the first connecting rod 407 and the first piston 410 to move synchronously.

[0023] Referring to Figures 1 - 5As shown, in a preferred embodiment, a first limiting ring 411 is fixedly installed on the surface of the first connecting rod 407. The first connecting rod 407 is hollow. A plurality of first through holes 412 are formed in the side wall of the first limiting ring 411. The first through holes 412 communicate with the hollow part of the first connecting rod 407. A first air duct 413 is formed in the inner cavity of the turntable 401. The first air duct 413 communicates with the hollow part of the first connecting rod 407. A plurality of negative pressure holes 414 are formed in the surface of the pressing die 403. The negative pressure holes 414 communicate with the first air duct 413. When the pressing die 403 is extruded and moves towards the inner cavity of the turntable 401, it drives the first connecting rod 407 and the first piston 410 to move synchronously. Under the action of the first piston 410, the air collecting cavity 409 on the side of the first limiting ring 411 is sucked, and the negative pressure holes 414 are sucked through the first air duct 413. Thus, during hot pressing, the sanitary napkin material is adsorbed on the surface of the pressing die 403, avoiding slippage of the sanitary napkin material with the first hot pressing strip 404 and the second hot pressing strip 405, and ensuring the hot pressing quality. A first motor 415 is fixedly installed on the side wall of the machine table 1 for driving the turntable 401 to rotate. Gears are installed at one end of the output end of the first motor 415 and the first rotating shaft 402, and the two gears are meshed. The first motor 415 can drive the turntable 401 to rotate through the gears. It should be noted that the parameters of the upper and lower first motors 415 and the related gears are exactly the same. The two first motors 415 are controlled to rotate in opposite directions through an external motor driver. Encoders are installed on each first motor 415, and the actual rotation speed of the first motor 415 is read by using the encoders. The encoder output is monitored by a microcontroller, and the PWM signal is adjusted to ensure that the speeds of the two first motors 415 are consistent.

[0024] In a preferred embodiment, during use, the first motor 415 can drive the turntables 401 on the upper and lower sides to rotate at the same speed in opposite directions. When the pressing dies 403 on the upper and lower sides contact and hot press the sanitary napkin, the pressing die 403 is extruded and moves towards the inner cavity of the turntable 401, driving the first connecting rod 407 and the first piston 410 to move synchronously. Under the action of the first piston 410, the air collecting cavity 409 on the side of the first limiting ring 411 is sucked, and the negative pressure holes 414 are sucked through the first air duct 413. Thus, during hot pressing, the sanitary napkin material is adsorbed on the surface of the pressing die 403, avoiding slippage of the sanitary napkin material with the first hot pressing strip 404 and the second hot pressing strip 405, and ensuring the hot pressing quality. After the hot pressing is completed, when the pressing dies 403 on both sides are separated from each other, the first spring 408 pushes the first piston 410 to reset, and the air in the air collecting cavity 409 is sprayed out from the negative pressure holes 414 again to dissipate heat from the hot-pressed sanitary napkin. At the same time, it blows the sanitary napkin away from the first hot pressing strip 404 and the second hot pressing strip 405, avoiding adhesion of the sanitary napkin to the first hot pressing strip 404 and the second hot pressing strip 405.

[0025] During the entire air extraction and inhalation cycle process, without the intervention of additional air sources and other power devices, a collaborative working mechanism of extrusion inhalation - forming blow - off (cooling) during the hot - pressing process is achieved. During the blowing process, the air flow can achieve the technical effect of first cooling the formed part after hot - pressing (weakening the adhesion between the formed part and the equipment) and then blowing it off. In this application, the air extraction and inhalation behaviors generated throughout the entire process of the air extraction and inhalation cycle are effectively utilized, maximizing the energy utilization rate of this part of the device. Through an action mechanism composed of a spring, a chamber, and a piston, functions such as adsorption and fixation during the hot - pressing of sanitary napkins, cooling after hot - pressing, and blow - off during the cooling process are achieved, etc., with various technical effects.

[0026] Referring to Figures 1 - 8 As shown, in a preferred embodiment, a brush mechanism 5 is installed on the side wall of the machine table 1 for brushing the sanitary napkin material.

After brushing, tiny burrs are added to the surface of the fibers, which helps to improve the uniformity of heat transfer. During subsequent hot - pressing, the material surface is more likely to uniformly absorb heat, thus ensuring the hot - pressing effect; spline teeth 503 are fixedly installed on the surface of the second rotating shaft 502, a spline groove 504 is provided in the inner cavity of the sleeve shaft 501, and the spline teeth 503 are engaged with the spline groove 504. With the cooperation of the spline teeth 503 and the spline groove 504, the second rotating shaft 502 can slide left and right while rotating synchronously with the sleeve shaft 501. A second motor 507 is fixedly installed on the side wall of the machine table 1 for driving the rotation of the sleeve shaft 501. Gears are installed at one end of both the second motor 507 and the sleeve shaft 501, and the two gears are engaged. The second motor 507 drives the rotation of the sleeve shaft 501 and the second rotating shaft 502 through the gears, so as to brush the surface of the material through the brush roller 505.

[0027] Referring to Figures 1 - 8As shown, in a preferred embodiment, a guide rod 508 is fixedly installed on the side wall of the machine table 1. A sliding plate 509 is slidably installed on the surface of the guide rod 508. The sliding plate 509 is rotatably connected to the second rotating shaft 502. One end of the guide rod 508 is fixedly installed with a second limiting ring 510. A second spring 511 is sleeved on the surface of the guide rod 508. One end of the second spring 511 is fixedly connected to the sliding plate 509, and the other end of the second spring 511 is fixedly connected to the second limiting ring 510, which is used to drive the sliding plate 509 to move towards the sleeve shaft 501. One end of the sleeve shaft 501 is fixedly installed with an arc-shaped driving ring 512. A convex block 513 is fixedly installed on the side wall of the sliding plate 509. When the second motor 507 drives the sleeve shaft 501 and the second rotating shaft 502 to rotate, the arc-shaped driving ring 512 is driven to rotate synchronously, and under the action of the second spring 511, the second rotating shaft 502 can be driven to swing left and right in the inner cavity of the sleeve shaft 501, driving the brush roller 505 to move synchronously, improving the brushing effect.

[0028] Refer to Figures 1 - 8 As shown, in a preferred embodiment, a first rotary joint 514 is installed at one end of the second rotating shaft 502. Both the second rotating shaft 502 and the brush roller 505 are hollow. One end of the hollow part of the second rotating shaft 502 is communicated with the first rotary joint 514, and the other end of the hollow part of the second rotating shaft 502 is communicated with the hollow part of the brush roller 505. A plurality of spray holes 519 are formed on the side wall of the brush roller 505. A second rotary joint 515 is installed at one end of the first rotating shaft 402. A first air cavity 516 and a second air passage 517 are formed in the inner cavity of the turntable 401. The first air cavity 516 is communicated with the air collecting cavity 409 through the second air passage 517. The first rotating shaft 402 is hollow. A second through hole 518 is formed on the side wall of the first rotating shaft 402. The hollow part of the first rotating shaft 402 is communicated with the first air cavity 516 through the second through hole 518, and the other end of the hollow part of the first rotating shaft 402 is communicated with the second rotary joint 515. A trachea is connected between the first rotary joint 514 and the second rotary joint 515. When the upper and lower pressing dies 403 come into contact to perform hot pressing on the sanitary napkin, the pressing die 403 is extruded and moves towards the inner cavity of the turntable 401, injecting the air in the air collecting cavity 409 into the hollow part of the first rotating shaft 402, and sending it into the hollow part of the brush roller 505 through the second rotary joint 515 and the first rotary joint 514, and finally spraying it out from the spray holes 519 onto the material surface, improving the fluffiness of the material, making the heat distribution more uniform during the hot pressing process, and improving the bonding effect.

[0029] In a preferred embodiment, the second motor 507 drives the sleeve shaft 501 and the second rotating shaft 502 to rotate through gears, so as to brush the surface of the material through the brush roller 505. When the second rotating shaft 502 rotates, it drives the arc-shaped driving ring 512 to rotate synchronously. Under the action of the second spring 511, the second rotating shaft 502 can be driven to swing left and right in the inner cavity of the sleeve shaft 501, driving the brush roller 505 to move synchronously, improving the brushing effect. In addition, when the upper and lower pressing dies 403 come into contact to perform hot pressing on the sanitary napkin, the pressing die 403 is extruded and moves towards the inner cavity of the turntable 401, injecting the air in the air collecting cavity 409 into the hollow part of the first rotating shaft 402, and sending it into the hollow part of the brush roller 505 through the second rotary joint 515 and the first rotary joint 514. Finally, it is ejected from the spray holes 519 onto the surface of the material, improving the fluffiness of the material, making the heat distribution more uniform during the hot pressing process, and improving the bonding effect.

[0030] Referring to Figures 1 - 10 As shown, in a preferred embodiment, a blanking mechanism 6 is installed on the side wall of the machine table 1 for blanking the hot-pressed sanitary napkins. The blanking mechanism 6 includes a guide plate 601, a collection box 602, and a blanking roller 603. The guide plate 601 is fixedly installed on the side wall of the machine table 1, and a collection box 602 is placed on the surface of the machine table 1 for collecting sanitary napkins. The blanking roller 603 is fixedly installed on the side wall of the machine table 1. Symmetrically arranged driving grooves 604 are formed in the inner cavity of the blanking roller 603. A second piston 605 is slidably installed in the driving grooves 604. A second connecting rod 606 is fixedly installed at the bottom of the second piston 605. One end of the second connecting rod 606 is fixedly installed with a push block 607 for pushing the hot-pressed sanitary napkin out of the material for blanking.

[0031] Referring to Figures 1 - 10As shown, in a preferred embodiment, a third spring 608 is sleeved on the surface of the second connecting rod 606. One end of the third spring 608 is fixedly connected to the second piston 605, and the other end of the third spring 608 is fixedly connected to the blanking roller 603, which is used to drive the second piston 605 to move upward. A third rotating shaft 609 is rotatably installed in the inner cavity of the blanking roller 603. Pulley wheels are fixedly installed on one end of the third rotating shaft 609 and the surface of the first rotating shaft 402. A belt is connected between the two pulley wheels. The diameter of the pulley wheel on the surface of the first rotating shaft 402 is four times that of the pulley wheel at one end of the third rotating shaft 609. That is to say, for every one revolution of the first rotating shaft 402, the third rotating shaft 609 rotates four times. The third rotating shaft 609 is hollow. A third through hole 610 is formed in the side wall of the third rotating shaft 609 for injecting air into the driving groove 604. An air hole 611 is formed among the second piston 605, the second connecting rod 606 and the pushing block 607. The diameter of the air hole 611 is smaller than that of the third through hole 610. A second air cavity 612 is formed in the inner cavity of the machine table 1. A fourth through hole 613 is formed in the side wall of the third rotating shaft 609. The hollow part of the third rotating shaft 609 is communicated with the second air cavity 612 through the fourth through hole 613. An air pump 614 is installed on the side wall of the machine table 1. A trachea is connected between the air outlet end of the air pump 614 and the second air cavity 612.

[0032] In a preferred embodiment, during use, whenever the upper and lower die presses 403 come into contact, the first rotating shaft 402 drives the third rotating shaft 609 to rotate one circle through the pulley wheels, so that the third through hole 610 is communicated with the driving groove 604, and then the driving groove 604 is injected with air through the air pump 614. Since the aperture of the third through hole 610 is larger than that of the air hole 611, a part of the air flow pushes the second connecting rod 606 to move downward, separates the sanitary napkin from the material through the pushing block 607, and conducts blanking. Another part of the air flow is ejected onto the surface of the sanitary napkin through the air hole 611 to dissipate heat from the sanitary napkin for the second time, ensuring the quality of the sanitary napkin.

[0033] Specifically, the working principle of the rare earth composite antibacterial sanitary napkin hot stamping device is as follows: When in use, the first motor 415 can drive the turntables 401 on the upper and lower sides to rotate at the same speed in opposite directions. When the upper and lower die sets 403 come into contact to hot stamp the sanitary napkin, the die sets 403 are extruded and move towards the inner cavity of the turntable 401, driving the first connecting rod 407 and the first piston 410 to move synchronously. Under the action of the first piston 410, the air collection cavity 409 on the side of the first limit ring 411 is suctioned, and the negative pressure holes 414 are aspirated through the first air passage 413. Thus, when hot stamping, the sanitary napkin material is adsorbed on the surface of the die set 403, preventing the sanitary napkin material from slipping relative to the first hot stamping strip 404 and the second hot stamping strip 405, and ensuring the hot stamping quality. After the hot stamping is completed, when the two die sets 403 separate from each other, the first spring 408 pushes the first piston 410 to reset, and the air in the air collection cavity 409 is sprayed out from the negative pressure holes 414 again to dissipate heat from the hot-stamped sanitary napkin. At the same time, it blows the sanitary napkin away from the first hot stamping strip 404 and the second hot stamping strip 405, preventing the sanitary napkin from sticking to the first hot stamping strip 404 and the second hot stamping strip 405.

[0034] The second motor 507 drives the sleeve shaft 501 and the second rotating shaft 502 to rotate through gears, so as to brush the surface of the material through the brush roller 505. When the second rotating shaft 502 rotates, it drives the arc-shaped driving ring 512 to rotate synchronously. Under the action of the second spring 511, the second rotating shaft 502 can be driven to swing left and right in the inner cavity of the sleeve shaft 501, driving the brush roller 505 to move synchronously, improving the brushing effect. In addition, when the upper and lower die sets 403 come into contact to hot stamp the sanitary napkin, the die sets 403 are extruded and move towards the inner cavity of the turntable 401, injecting the air in the air collection cavity 409 into the hollow part of the first rotating shaft 402, and sending it into the hollow part of the brush roller 505 through the second rotary joint 515 and the first rotary joint 514, and finally spraying it out from the spray holes 519 onto the surface of the material, improving the fluffiness of the material, making the heat distribution more uniform during the hot stamping process, and improving the bonding effect.

[0035] Whenever the upper and lower die sets 403 come into contact, the first rotating shaft 402 drives the third rotating shaft 609 to rotate one circle through the pulley, making the third through hole 610 communicate with the driving groove 604. Thus, the air pump 614 injects air into the driving groove 604. Since the aperture of the third through hole 610 is larger than that of the air hole 611, a part of the air flow pushes the second connecting rod 606 downward, separating the sanitary napkin from the material through the push block 607 for blanking. Another part of the air flow is sprayed out onto the surface of the sanitary napkin through the air hole 611 to dissipate heat from the sanitary napkin again, ensuring the quality of the sanitary napkin.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
