Description

Technical Field

[0001] This invention relates to the field of absorbent core forming equipment, and more particularly to an absorbent core forming apparatus for medical and health applications. Background Technology

[0002] In the medical and health field, absorbent cores are core functional components of products such as sanitary napkins, diapers, and medical pads. Their molding quality directly determines the product's liquid absorption rate, water retention capacity, and user comfort, which is crucial for ensuring user health and experience. Currently, traditional absorbent core molding equipment suffers from numerous technical bottlenecks, making it difficult to meet the production demands of high-performance medical and health products. Traditional equipment generally employs a multi-negative-pressure chamber design, requiring frequent negative-pressure alignment and machine stop adjustments during mold rotation. This prevents the vacuum equipment from achieving continuous and stable operation, reducing production cycle time and easily causing uneven fiber distribution and density deviations in the absorbent core due to pressure fluctuations, affecting the consistency of product absorbency. Furthermore, the traditional mold wheel's adsorption hole assembly is a fixed structure... If absorbent core products with different thicknesses and different absorption gradients (such as high density in the core area and breathable edge area) need to be produced, the entire set of molds must be replaced after shutdown. This operation is cumbersome and time-consuming, which greatly limits production flexibility and equipment utilization. It is difficult to adapt to the customized needs of diverse medical and health scenarios. During the raw material molding process, excess loose fiber raw materials in the mold cavity are difficult to clean effectively, which easily leads to residual material. This results in defects such as excessive thickness and blockage of absorption channels in subsequent products, reducing the product qualification rate. This not only affects the continuity of production, but may also cause edge damage and structural deformation of the absorbent core, further restricting the production efficiency and quality improvement of absorbent core products for medical and health use. Therefore, we propose a medical and health absorbent core molding device to solve the above-mentioned problems. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention abandons the traditional multi-negative-pressure-cavity design. By separating the wheel body from the hole assembly, the negative-pressure-cavity is simplified into a single stable channel, enabling the vacuum equipment to operate continuously without interruption. This eliminates the need for frequent machine stops for alignment due to mold wheel rotation, significantly reducing production downtime and improving overall production cycle time and efficiency. It is more suitable for large-scale mass production, making the absorbent core production process smoother and significantly increasing output per unit time. Furthermore, the stable negative-pressure environment avoids fiber distribution deviations, ensuring the consistency of the basic structure of each batch of absorbent cores under large-scale mass production. It is fully compatible with the mass production needs of medical and health products such as sanitary napkins and diapers.

[0016] 2. This invention precisely controls the amount of fiber raw material adsorbed by preset vacuum pump adsorption power, and uses low-power air extraction equipment to clean up excess loose raw material in the mold cavity. This ensures that only the amount of material used in a single molding process is retained in the upper chamber, effectively avoiding product deviations caused by residual material from the previous molding process. At the same time, it maintains the amount of raw material adsorbed in the mold cavity within a reasonable range, significantly reducing the defect rate and ensuring the overall uniformity of the absorbent core density. This avoids the problems of local liquid saturation and local lack of liquid absorption capacity, and significantly improves the consistency of absorbent core molding quality and reliability.

[0017] 3. This invention utilizes gas from the vacuum pump outlet, which is introduced into the chassis via the inlet pipe and conduit. This creates a directional airflow impact on the lower mold cavity, and combined with gravity, enables rapid and non-destructive demolding of the absorbent core. This completely solves the adhesion problem, ensuring that the absorbent core has neat edges and that its internal structure is not damaged. This ensures that its liquid absorption speed and water-locking ability are not affected. At the same time, the gas can backflush the corresponding hole groups one and two on the side plate to prevent fiber material from blocking the adsorption channels. This, combined with the material extraction pipe in the lower chamber, allows for timely extraction of residual raw materials, avoiding equipment downtime due to malfunctions, reducing maintenance and cleaning time, ensuring continuous and stable operation of the production line, and further reducing product quality fluctuations caused by equipment failures.

[0018] 4. This invention uses a geared motor to drive a drive gear, which in turn rotates the rotating ring, fixed ring, and slip ring. It allows switching between hole group one and hole group two with different apertures and distribution areas, enabling rapid adjustment of the absorbent core thickness distribution without stopping the machine to change the mold. Furthermore, it can use a servo motor to drive a threaded rod to adjust the slip ring position, causing the hole groups to be misaligned and changing the ventilation aperture. Combined with the lead screw adjustment of the distance between the vacuum disk and the mold cavity, it achieves dual precise fine-tuning of the adsorption force. This invention can produce customized absorbent cores with high density in the core area and air permeability in the edge area, and can also adapt to products with different thicknesses and different liquid absorption requirements, greatly improving the equipment's versatility and product adaptability flexibility, and meeting the customized production needs of diverse medical and health scenarios.

[0028] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] like Figures 1-8 The device for forming absorbent cores for medical and health use includes a wheel body 101. A uniformly distributed mold cavity 120 is opened in the middle of the outer periphery of the wheel body 101. A fixed frame 114 is fixedly connected to the rear side of the top chamber 104. A drive chamber 112 is fixedly connected to the lower rear side of the fixed frame 114. A geared motor is installed inside the drive chamber 112. The drive end of the geared motor is fixedly connected to the drive gear 117. A base frame 111 is provided on both the front and rear sides of the wheel body 101. A connecting flange 116 is fixedly connected to the middle of the rear side of the wheel body 101. A stepper motor 140 is installed on the upper part of the rear base frame 111. The drive end of the stepper motor 140 is fixedly connected to the connecting flange 116. Mounting frames 107 are fixedly connected to the upper parts of both sides of the base frame 111. The end of the mounting frame 107 away from the base frame 111 is fixedly connected to both sides of the fixed chamber 106. The rear part of the rotating ring 115 is rotatably connected to the adjacent mounting frame 107.

[0030] Furthermore, in specific implementation, the absorption core can be formed using a molding die. Specifically, the raw material feeding device introduces the production material into the feed inlet 102, which in turn introduces the material into the upper chamber 124. Then, the stepper motor 140 is started, which, through the connecting flange 116, drives the wheel 101 to rotate, causing the mold cavity 120 around the wheel 101 to rotate to the bottom of the top chamber 104. Finally, the vacuum pump is started, and through the vacuum pipe 109, the vacuum disc is extracted. The air above 136 creates a negative pressure environment above the inner chamber 125. Through negative pressure adsorption, the fiber material inside the upper chamber 124 is drawn into the vacuum disk 136. By limiting the material, the mold cavity 120 is filled. By changing the traditional multi-negative-pressure chamber setup and changing the shape of the mold wheel to separate the wheel body 101 from the hole group 119, the negative pressure chamber can be reduced to one. This transforms the traditional rotational alignment adsorption into a stable vacuum channel, allowing the vacuum equipment to work continuously without stopping for each shaping rotation, which is beneficial for practical use.

[0031] Among them, a fixed ring 131 and a slip ring 130 are slidably connected inside the rear side of the peripheral wall of the wheel body 101. The fixed ring 131 is slidably connected to the outer periphery of the slip ring 130. A rotating ring 115 is fixedly connected to the rear end of the fixed ring 131. A toothed groove 113 is opened in the rear part of the inner side of the rotating ring 115. A drive gear 117 is meshed in the toothed groove 113 on one side. Multiple servo motors 133 are installed in the front part of the inner side of the rotating ring 115. A threaded rod 132 is fixedly connected to the drive end of each servo motor 133. The front part of each threaded rod 132 is threadedly connected to the inside of the wall of the slip ring 130. Multiple hole groups 2 134 are opened in the periphery of the slip ring 130. Multiple hole groups 119 are opened in the periphery of the fixed ring 131. Hole groups 119 and hole groups 2 134 are corresponding to the mold cavity 120.

[0032] Furthermore, in specific implementation, the fixed frame 114 drives the drive gear 117 to rotate. The drive gear 117, through its meshing tooth groove 113, drives the rotating ring 115 to rotate synchronously. The rotating ring 115 drives the fixed ring 131 and the slip ring 130 to rotate, thereby rotating the remaining pore groups 119 and 134 to the upper part, realizing the switching of the adsorption area. The pore size variation and distribution area of ​​each different pore group 119 and 134 are different, thus enabling the adsorption of fiber raw materials into different thickness distributions. This allows the fixed ring to be rotated. The 131 and slip ring 130 can adjust the specifications of the molded absorbent core without stopping the machine to change the mold, which is convenient for practical use. The servo motor 133 can be started, which can drive the threaded rod 132 to rotate. The threaded rod 132 can drive the slip ring 130 to move. The movement of the slip ring 130 can cause the hole group one 119 and the hole group two 134 to be misaligned. The misalignment of the hole group one 119 and the hole group two 134 can change the size of the vent hole at the mold cavity 120, thereby adjusting the magnitude of the adsorption force, further realizing micro-adjustment, and improving the quality of the finished absorbent core.

[0033] The wheel body 101 is rotatably connected to the center of the front side of the mounting plate 110. A bracket 127 is installed on the rear side of the mounting plate 110. An outer chamber 126 is installed on the upper inner side of the bracket 127. An inner chamber 125 is installed on the inner side of the outer chamber 126. The top of the inner chamber 125 corresponds to the uppermost mold cavity 120. A vacuum plate 136 is slidably connected to the upper part of the inner chamber 125. An air extraction pipe 109 is installed in the middle of the vacuum plate 136. A corrugated section 139 is provided in the middle section of the air extraction pipe 109. A slide 129 is fixedly connected to both sides of the bottom of the vacuum plate 136. The outer compartment 126 and the inner compartment 125 are both provided with slots 128 on both sides of the lower part. The slide 129 is slidably connected to the inner compartment 125 and the outer compartment 126 through the slots 128. The front part of the suction pipe 109 passes through the inner compartment 125, the outer compartment 126 and the mounting plate 110 in sequence. The end of the suction pipe 109 away from the vacuum plate 136 is connected to an external vacuum pump. Multiple limit rods 138 and a lead screw 137 pass through the front and rear parts of the slide 129. The lead screw 137 is threadedly connected to the slide 129. The limit rods 138 are all slidably connected to the slide 129.

[0034] Furthermore, in specific implementation, during the adsorption process, the operation of the lead screw 137 can drive the slide 129 to move up and down, and the slide 129 can drive the vacuum disk 136 to move synchronously. By adjusting the position of the vacuum disk 136, the distance between the negative pressure suction source and the mold cavity 120 can be changed, thereby achieving the adjustment of the adsorption force without changing the working power of the vacuum pump, which is beneficial for practical use.

[0035] Among them, a fixed chamber 106 is rotatably connected to the upper outer periphery of the wheel body 101. A partition 121 is fixedly connected to the middle of both sides of the fixed chamber 106. The upper inner side of the fixed chamber 106 is divided into an upper chamber 124 by the partition 121. An air intake 103 and a feed inlet 102 are respectively installed on the top two sides of the upper chamber 124. A top chamber 104 is installed at the middle of the top of the fixed chamber 106. The feed inlet 102 is used to connect to the raw material feeding equipment, and the air intake 103 is used to connect to the air extraction equipment. A pressure plate 122 is slidably connected inside the top chamber 104. A hydraulic rod 105 is installed on the top of the top chamber 104. The bottom drive end of the hydraulic rod 105 is fixedly connected to the top of the pressure plate 122. The bottom of the pressure plate 122 corresponds to the uppermost mold cavity 120 of the wheel body 101.

[0036] Furthermore, in specific implementation, the working power of the vacuum pump is preset so that the negative pressure generated is just enough to adsorb the required amount of fiber raw material. Then, the air extraction device connected to the feed port 102 can be started. The air extraction device has a small working power. The air extraction device can remove or change the position of excess or loose fiber raw material inside the mold cavity 120, so that the amount of raw material adsorbed inside the mold cavity 120 can remain within a stable range. In conjunction with the raw material replenishment device, it can ensure that there is only a single amount of material in the upper chamber 124 for each shaping, avoiding deviations and defects due to residual material from the previous shaping after multiple shapings, and further improving the stability of the shaping work. After the raw material adsorption is completed, the operation of the fixing frame 114 can drive the pressure plate 122 to press down. The pressure plate 122 can compress and shape the fiber raw material inside the lower mold cavity 120. Under high pressure, the loose fiber raw material will be compressed into a preset, dense shape to form the final "absorbent core" product.

[0037] Among them, a side plate 135 is provided on one side of the middle part of the wheel body 101. The side plate 135 corresponds to the mold cavity 120 on the same side of the wheel body 101. An air inlet pipe 108 is fixedly connected to the middle of the side plate 135. The end of the air inlet pipe 108 away from the side plate 135 passes through one side of the middle of the mounting plate 110. The air inlet pipe 108 is used to connect to the air outlet of the vacuum pump. A conduit 142 is fixedly connected to the bottom of the air inlet pipe 108. A base plate 141 is fixedly connected to the end of the conduit 142 away from the air inlet pipe 108. The base plate 141 is located in the lower part of the wheel body 101. The base plate 141 corresponds to the mold cavity 120 on the lower side. The lower part of the inner side of the fixed chamber 106 is divided into a lower chamber 123 by a partition 121. A material extraction pipe 118 is fixedly connected to the bottom of the lower chamber 123. The material extraction pipe 118 is used to connect to the air extraction equipment.

[0038] Furthermore, in specific implementation, after molding, the stepper motor 140 drives the wheel 101 to continue rotating for the next adsorption and shaping process. During rotation, the through-hole on the suction pipe 109 maintains a certain negative pressure inside the wheel 101, ensuring the absorbent core is stabilized inside the mold cavity 120. When the shaped absorbent core is rotated to the lower part, the mold cavity 120 is rotated to the chassis 141. The gas output from the vacuum pump is introduced into the chassis 141 by the inlet pipe 108 and the conduit 142, further stimulating the mold core that has been rotated to the lower side. The cavity 120 is impacted, and under the action of gravity and gas, the absorber core will leave the cavity 120 and fall onto the lower conveyor belt, completing the demolding process. In actual use, the gas generated by the vacuum pump during operation will be introduced into the side plate 135 through the air inlet pipe 108, thereby achieving backflushing of the first hole group 119 and the second hole group 134 on that side, preventing fiber material from getting stuck on the first hole group 119 or the second hole group 134. The suction device can use the suction pipe 118 to suction the interior of the lower chamber 123, thereby removing any residual or backflushed fiber material that may affect subsequent adjustment and molding work.

[0039] Working principle:

[0040] In practical use, the absorbent core can be formed using a molding die. Specifically, the material is fed into the inlet 102 via a material feeding device, which then guides it into the upper chamber 124. Next, a stepper motor 140 is started, which, via the connecting flange 116, rotates the wheel 101, causing the mold cavity 120 around the wheel 101 to rotate to the bottom of the top chamber 104. Then, a vacuum pump is activated, using the extraction pipe 109 to draw air from the upper part of the vacuum disc 136, creating a negative pressure environment in the upper part of the inner chamber 125. This negative pressure adsorption draws the fiber material from the upper chamber 124 into the vacuum disc 136. Inside the mold cavity 120, the material is limited to fill the cavity. By changing the traditional multi-negative-pressure chamber setup and altering the mold wheel shape to separate the wheel 101 from the hole group 119, the negative-pressure chamber can be reduced to a single chamber. This transforms the traditional rotational alignment adsorption into a stable vacuum channel, allowing the vacuum equipment to operate continuously without stopping for each shaping rotation, which is beneficial for practical use. The working power of the vacuum pump is preset so that the negative pressure generated is just enough to adsorb the required amount of fiber material. Then, the suction device connected to the inlet 102 can be activated. The suction device has a relatively low working power, which can remove or reposition excess or loose fiber material inside the mold cavity 120, thus making the mold... The amount of raw material adsorbed inside cavity 120 can remain stable within a certain range. In conjunction with the raw material replenishment equipment, it ensures that only the amount of material used in a single shaping cycle exists in upper cavity 124, preventing deviations and defects caused by residual material from previous shaping cycles. This further improves the stability of the shaping process. After the raw material adsorption is complete, the fixing frame 114 drives the pressure plate 122 to press down. The pressure plate 122 compresses and shapes the fiber raw material inside the lower mold cavity 120. Under high pressure, the loose fiber raw material is compressed into a preset, dense shape, forming the final "absorbent core" product. After shaping, the stepper motor 140 drives the wheel 101 to continue rotating for the next adsorption and shaping cycle. During rotation, the suction... The through-hole on the air pipe 109 maintains a certain negative pressure inside the wheel 101, ensuring the absorber core remains stable within the mold cavity 120 during rotation. When the shaped absorber core rotates to the lower part, the mold cavity 120 rotates to the chassis 141. The gas from the vacuum pump's output end is guided into the chassis 141 by the air inlet pipe 108 and the conduit 142, further impacting the lowered mold cavity 120. Under the influence of gravity and gas, the absorber core leaves the mold cavity 120 and falls onto the lower conveyor belt, completing the demolding process. In actual use, the gas generated by the vacuum pump during operation is guided into the side plate 135 through the air inlet pipe 108, thereby achieving backflushing of the first hole group 119 and the second hole group 134 on that side.To prevent fiber material from getting stuck in hole group one 119 or hole group two 134, the suction device uses the suction pipe 118 to draw out the lower chamber 123, thus removing any residual or backflowed fiber material that could affect subsequent adjustment and molding. During production, the fixed frame 114 drives the drive gear 117 to rotate. The drive gear 117, through its meshing tooth groove 113, drives the rotating ring 115 to rotate synchronously. The rotating ring 115 then drives the fixed ring 131 and the slip ring 130 to rotate, thus rotating the remaining hole groups one 119 and two 134 to the upper part, switching the adsorption area. Each different hole group one 119 and two 134 has a different pore size and distribution area, allowing the fiber material to be adsorbed into different thicknesses. This allows the specifications of the molding absorbent core to be adjusted simply by rotating the fixed ring 131 and the slip ring 130, without the need for... The machine can be stopped and the mold replaced for convenient practical use. During the adsorption process, the operation of the lead screw 137 drives the slide 129 to move up and down, which in turn drives the vacuum disk 136 to move synchronously. By adjusting the position of the vacuum disk 136, the distance between the negative pressure suction source and the mold cavity 120 can be changed, thus adjusting the adsorption force without changing the working power of the vacuum pump, which is beneficial for practical use. Furthermore, the servo motor 133 can be started, which drives the threaded rod 132 to rotate. The threaded rod 132 drives the slip ring 130 to move. The movement of the slip ring 130 causes the hole group one 119 and the hole group two 134 to be misaligned. This misalignment changes the size of the vent hole at the mold cavity 120, thereby adjusting the adsorption force and achieving fine adjustment, improving the quality of the finished absorbent core.
