Description

Technical Field

[0001] This invention relates to the field of medical sanitary napkin wick forming equipment, and more particularly to a medical sanitary napkin wick forming device. Background Technology

[0002] In practical applications of medical sanitary napkin wick forming equipment, traditional devices generally suffer from low forming efficiency, poor quality control of finished products, and insufficient smoothness in the connection between various processes. Traditional equipment is prone to material clumping and inaccurate feeding control during material feeding, resulting in uneven material thickness adsorbed in the mold cavity. This leads to inconsistent density and shape of the subsequently pressed wicks, resulting in a low finished product qualification rate. Simultaneously, the vacuum adsorption structure lacks an effective material cutting design; the negative pressure during mold wheel rotation easily leads to continuous material adsorption, not only interfering with equipment operation but also causing material accumulation at the adsorption site, further affecting the adsorption effect of the formed sanitary napkin wick. Furthermore, traditional devices rely solely on gravity for wick demolding, which easily leads to material jamming and cavity sticking, requiring manual assistance and interrupting the production process. Moreover, most processes are step-by-step operations, with adsorption, pressing, and demolding unable to be performed simultaneously, resulting in low overall equipment efficiency and difficulty in meeting the large-scale, standardized production needs of medical sanitary napkins. Therefore, we propose a medical sanitary napkin wick forming device to solve the aforementioned problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a medical sanitary napkin core forming device.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a medical sanitary napkin core forming device, comprising a body, a cover installed on the top of the body, fixed plates fixedly connected to the front and rear sides of the middle of the body, a rotating shaft rotatably connected to the middle of the fixed plates, a servo motor fixedly connected to the rear end of the rear fixed plate, the drive end of the servo motor being fixedly connected to the end of the rotating shaft, a mold wheel installed in the middle of the outer circumference of the rotating shaft, a vacuum chamber installed inside the mold wheel, multiple vacuum chambers being provided inside the vacuum chamber, multiple cavities being opened in the middle of the outer circumference of the mold wheel, and a grid plate installed inside each cavity. Corresponding to the vacuum chamber, a partition plate is fixedly connected to the upper middle part of the machine body. The upper part of the machine body is divided into inner cavity one and inner cavity two by the partition plate. A feed port is installed at the upper part of one end of the machine body and is connected to inner cavity one. A fixed frame is installed on one side of inner cavity one. A slide is slidably connected to the lower part of the fixed frame. A top plate is fixedly connected to the top of both the fixed frame and the slide. A toothed column is provided in the middle between the top plates. A reduction motor is installed on the top of the toothed column. The reduction motor is installed inside the machine cover. A toothed groove is opened on one side of the middle part of the top plate of the slide. The toothed column is engaged with the toothed groove.

[0005] Preferably, a plurality of straight pipes are installed on one side of the vacuum chamber, and the straight pipes correspond to the vacuum cavities inside the vacuum chamber, and an annular chamber is installed at the front end of the mold wheel.

[0006] Preferably, the end of the straight tube furthest from the vacuum chamber is located inside the annular chamber, and the front of the mold wheel is rotatably connected to a fixed ring through the annular chamber.

[0007] Preferably, the fixing ring is installed at the rear end of the front fixing plate, and sliding plates are fixedly connected to both sides of the middle part of the fixing ring, and the sliding plates are rotatably connected inside the ring chamber.

[0008] Preferably, the top of the fixing ring is fixedly connected to multiple connecting pipes, and the top of each connecting pipe is fixedly connected to a connecting pipe, which is installed on the upper front end of the machine body.

[0009] Preferably, a plurality of connecting pipes are fixedly connected to one side of the bottom of the connecting pipe, a pump body is installed inside the machine body, and a connecting pipe is installed and connected to the output end of the pump body.

[0010] Preferably, a connecting frame is fixedly connected to one side of the inner cavity, and a fixed shell is fixedly connected to the end of the connecting frame. Multiple hydraulic rods are installed inside the fixed shell, and pressure plates are installed at the telescopic ends of the hydraulic rods. The pressure plates are slidably connected to the inner wall of the fixed shell.

[0011] Preferably, annular grooves are provided on both sides of the outer periphery of the mold wheel, and limit strips are fixedly connected to both sides of the inner arc surface in the middle of the machine body, and the limit strips slide with the annular grooves.

[0012] Preferably, a conveyor belt is installed at the lower part of the machine body, and the conveyor belt has evenly distributed fine grooves in the middle. Both sides of the inner side of the conveyor belt are provided with drive rollers, and stepper motors are installed at the ends of the drive rollers.

[0013] Preferably, a support chamber is provided in the middle of the inner side of the conveyor belt, and the top of the support chamber is provided with evenly distributed through holes. The output end of the pump body is connected to the inside of the support chamber through a connecting pipe.

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

[0015] This invention uses a geared motor to drive the toothed column to rotate, which in turn drives the slide and the fixed frame to perform a synchronous reciprocating "interlaced shearing" motion. This not only achieves precise intermittent control of material entry, but also effectively breaks up clumps of material, avoiding local accumulation and uneven thickness when the cavity adsorbs material, thus laying a uniform material foundation for subsequent pressing and molding.

[0016] After the material in the cavity is adsorbed, the present invention uses a toothed column to drive the slide and the fixed frame to misalign and form a "closed partition", which cuts off the continuous introduction of material. This solves the problem of continuous material entry and interference with the rotation of the mold wheel caused by vacuum negative pressure adsorption in traditional equipment. At the same time, it avoids the problem of excessive local thickness caused by material accumulation at the adsorption position before the rear empty cavity is in place, and ensures the stability of the connection between the rotation of the mold wheel and the adsorption process.

[0017] In this invention, when the pressed cotton core rotates with the mold wheel to the conveyor belt, the sliding plate cuts off the adsorption force of the corresponding vacuum cavity, allowing the cotton core to initially detach from the cavity under the action of gravity. At the same time, the pump body forms a negative pressure at the conveyor belt through the support chamber, and uses the fine grooves on the conveyor belt to accurately suck the cotton core out of the cavity. The dual structure effectively avoids the problems of material jamming and sticking to the cavity during demolding of traditional equipment, ensuring the smoothness of demolding and conveying.

[0018] This invention enables the continuous and synchronous execution of four processes—material adsorption, hydraulic pressing, cotton core demolding, and finished product conveying—through the rotation of the mold wheel. When one cavity completes pressing, the next cavity simultaneously completes material adsorption. At the same time as demolding, the finished product is exported with the conveyor belt. There is no waiting connection between the processes. Compared with traditional step-by-step equipment, this invention significantly improves the overall forming and production efficiency of cotton cores. Attached Figure Description

[0029] 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.

[0030] like Figures 1-9 The device shown is a medical sanitary napkin core forming device, including a body 101. A cover 103 is installed on the top of the body 101. Fixing plates 107 are fixedly connected to both the front and rear sides of the middle of the body 101. A rotating shaft 108 is rotatably connected to the middle of the fixing plates 107. A servo motor 113 is fixedly connected to the rear end of the rear fixing plate 107. The drive end of the servo motor 113 is fixedly connected to the end of the rotating shaft 108. A mold wheel 111 is installed on the middle of the outer periphery of the rotating shaft 108. Annular grooves 124 are formed on both sides of the outer periphery of the mold wheel 111. Limiting strips 129 are fixedly connected to both sides of the inner arc surface of the middle of the body 101. The limiting strips 129 slide against the annular grooves 124. A vacuum chamber 133 is installed inside the mold wheel 111. The vacuum chamber 133 has multiple vacuum cavities. Multiple cavities 110 are provided in the middle of the outer periphery of the machine body 111. Each cavity 110 is equipped with a grid plate 125. The grid plate 125 is used to ensure the uniform transmission of vacuum adsorption force and prevent material from entering the vacuum cavity and causing blockage. Each cavity 110 corresponds to a vacuum cavity. A partition plate 115 is fixedly connected to the upper middle part of the machine body 101. The upper part of the machine body 101 is divided into inner cavity one 114 and inner cavity two 117 by the partition plate 115. Inner cavity one 114 is the material adsorption station, and inner cavity two 117 is the cotton core pressing and forming station. A feed port 102 is installed at the upper part of one end of the machine body 101. The feed port 102 is connected to inner cavity one 114. A pump body 120 is installed on one side of the machine body 101. A connecting pipe two 106 is installed and connected to the output end of the pump body 120.

[0031] Furthermore, in specific implementation, the medical cotton core forming equipment can be used to form the cotton core. Specifically, the material can be introduced into the inner cavity 114 through the feed port 102. At the same time, the pump 120 inside the machine body 101 can be activated. The operation of the pump 120 can extract the gas in the fixing ring 109 through the connecting pipe 106, the connecting pipe 105 and the connecting pipe 104. Through the connection between the ring chamber 127 and the straight pipe 126, the vacuum chamber inside the vacuum chamber 133 can be further evacuated. When the material enters the inner cavity 114, it can be adsorbed into the cavity 110 through vacuum adsorption, so that the material is tightly attached to the grid plate 125, which is convenient for subsequent pressing and forming.

[0032] A fixed frame 119 is installed on one side of the inner cavity 114. A slide 130 is slidably connected to the lower part of the fixed frame 119. A top plate 121 is fixedly connected to the top of both the fixed frame 119 and the slide 130. A toothed column 131 is provided in the middle between the top plates 121. A reduction motor is installed on the top of the toothed column 131. The reduction motor is installed inside the cover 103. A toothed groove 132 is opened on one side of the middle of the top plate 121 at the top of the slide 130. The toothed column 131 is meshed with the toothed groove 132.

[0033] Furthermore, in specific implementation, during the material adsorption process, the operation of the reduction motor inside the cover 103 can drive the toothed column 131 to rotate. The toothed column 131 can drive the top plate 121 and the slide 130 on one side to move through the meshing tooth groove 132. Through the back and forth rotation of the toothed column 131, the tooth groove 132 can drive the top plate 121 and the slide 130 to move synchronously back and forth, so that the slide 130 and the fixed frame 119 will perform "interlaced shearing". This allows for intermittent control of the material entering during material adsorption, and at the same time, it can break up clumps of material, avoiding uneven thickness of material in the cavity 110 during adsorption, which would affect the quality of the finished product after subsequent molding.

[0034] Multiple straight pipes 126 are installed on one side of the vacuum chamber 133, each corresponding to a vacuum cavity inside the vacuum chamber 133. An annular chamber 127 is installed at the front end of the mold wheel 111. The ends of the straight pipes 126 furthest from the vacuum chamber 133 are all located inside the annular chamber 127. A fixed ring 109 is rotatably connected to the front of the mold wheel 111 via the annular chamber 127. The fixed ring 109 is installed at the rear end of the front fixed plate 107. Sliding plates 128 are fixedly connected to both sides of the middle part of the fixed ring 109. The sliding plates 128 are rotatably connected inside the annular chamber 127. The sliding plates 128 are fixed structures. When the wheel 111 drives the ring chamber 127 to rotate, the sliding plate 128 only keeps the vacuum chamber of the corresponding adsorption / pressing station connected under negative pressure, while the vacuum chambers of other stations are blocked by the sliding plate 128, thus achieving precise station control of negative pressure. As the mold wheel 111 rotates, the negative pressure passage of the vacuum chamber at non-station locations can be cut off by the sliding plate 128. The top of the fixed ring 109 is fixedly connected to multiple connecting pipes 104, and the top of each connecting pipe 104 is fixedly connected to a connecting pipe 105. The connecting pipe 105 is installed on the upper front end of the machine body 101, and multiple connecting pipes 106 are fixedly connected to one side of the bottom of the connecting pipe 105.

[0035] Furthermore, in specific implementation, after the material in cavity 110 at inner cavity 114 is adsorbed, the servo motor 113 drives the rotating shaft 108 to rotate. During this process, the toothed column 131 can use the toothed groove 132 to drive the slide 130 to move, thereby misaligning the fixed frame 119 and forming a "closed partition" to cut off the continuous introduction of material. This prevents the material from continuously entering and affecting the rotation of the mold wheel 111 due to the vacuum negative pressure. At the same time, it prevents the material from accumulating at the initial adsorption position when the rear empty cavity 110 is gradually in place, which would cause the local material accumulation in the cavity 110 to be too thick. During this process, the connecting pipe 134 can connect to the support chamber 135 in the middle of the conveyor belt 112, generating a negative pressure environment in the support chamber 135. This negative pressure can adsorb the molded medical cotton core product through the fine grooves on the conveyor belt 112, thereby sucking it out of the cavity 110, avoiding material jamming, and facilitating practical use.

[0036] Among them, a connecting frame 118 is fixedly connected to one side of the inner cavity 117, and a fixed shell 116 is fixedly connected to the end of the connecting frame 118. Multiple hydraulic rods 122 are installed inside the fixed shell 116, and pressure plates 123 are installed at the telescopic ends of the hydraulic rods 122. The pressure plates 123 are slidably connected to the inner wall of the fixed shell 116.

[0037] Furthermore, in specific implementation, the rotating shaft 108 can drive the mold wheel 111 to rotate synchronously with the internal vacuum chamber 133. The servo motor 113 can rotate the material-filled cavity 110 from the inner cavity one 114 to the inner cavity two 117, and make it correspond to the fixed shell 116. At this time, the next empty inner cavity one 114 begins to absorb material, and at the same time, the hydraulic rod 122 inside the fixed shell 116 starts to work. The extension of the hydraulic rod 122 can drive the pressure plate 123 to extend. The pressure plate 123 can press and shape the material in the cavity 110 at that time.

[0038] The lower part of the machine body 101 is equipped with a conveyor belt 112. The conveyor belt 112 has evenly distributed fine slots in the middle. Both sides of the inner side of the conveyor belt 112 are equipped with drive rollers. The ends of the drive rollers are equipped with stepper motors. The middle of the inner side of the conveyor belt 112 is equipped with a support chamber 135. The top of the support chamber 135 has evenly distributed through holes. The output end of the pump body 120 is connected to the inside of the support chamber 135 through a connecting pipe 134.

[0039] Furthermore, in specific implementation, after the pressing and adsorption of the inner cavity 114 are completed, the servo motor 113 rotates the mold wheel 111 by another angle, thereby rotating the cavity 110 containing the pressed cotton core to the conveyor belt 112. At this time, the straight pipe 126 communicating with the cavity 110 is rotated to the lower part of the fixing ring 109. Under the separation effect of the sliding plate 128, the straight pipe 126 at the lower part and the vacuum chamber in the vacuum chamber 133 communicating with it lose the adsorption force, so that the formed cotton core in the cavity 110 can fall onto the conveyor belt 112 under the action of gravity. The stepper motor and drive roller at the end of the conveyor belt 112 can drive the conveyor belt 112 to circulate and transport. The operation of the conveyor belt 112 can further transport the cotton core and complete the medical cotton core export work.

[0040] Working principle:

[0041] In practical use, the medical cotton core forming equipment can be used to form cotton cores. Specifically, material is introduced into the inner cavity 114 through the feed inlet 102. Simultaneously, the pump 120 inside the machine body 101 is activated. The pump 120 uses the connecting pipe 106, connecting pipe 105, and connecting pipe 104 to extract gas from the fixing ring 109. Through the connection between the ring chamber 127 and the straight pipe 126, a vacuum is further created inside the vacuum chamber 133. This allows the material to be drawn into the inner cavity 114 through vacuum adsorption, causing it to adhere tightly to the grid plate 125, facilitating subsequent pressing and forming. During the material adsorption process, the operation of the geared motor inside the cover 103 drives the toothed column 131 to rotate. The toothed column 131, through its meshing tooth groove 132, moves the top plate 121 and the slide 130 on one side. The back-and-forth rotation of the toothed column 131, via the tooth groove 132, causes the top plate 121 and the slide 130 to move synchronously back and forth, resulting in a "cross-cutting" interaction between the slide 130 and the fixed frame 119. This allows for intermittent control of material entry during adsorption and also breaks up clumps of material, preventing uneven material thickness within the cavity 110 during adsorption, which could affect the quality of the final product after molding. Once the material in the cavity 110 at inner cavity 114 has been adsorbed... The servo motor 113 drives the rotating shaft 108 to rotate. During this process, the toothed column 131 uses the toothed groove 132 to drive the slide 130 to move, achieving misalignment of the fixed frame 119 and forming a "closed partition" to cut off the continuous introduction of material. This prevents material from continuously entering and affecting the rotation of the mold wheel 111 due to the vacuum negative pressure. It also prevents material from accumulating at the initial adsorption position when the rear empty cavity 110 gradually enters its position, thus avoiding excessive local material accumulation in the cavity 110. The rotating shaft 108 drives the mold wheel 111 to rotate synchronously with the internal vacuum chamber 133. The servo motor 113 moves the material-filled cavity 110 from the inner cavity to the outer cavity 111. The material is rotated to the inner cavity 117, aligning with the fixed shell 116. At this point, the next empty inner cavity 114 begins to absorb material. Simultaneously, the hydraulic rod 122 inside the fixed shell 116 begins to operate. The extension of the hydraulic rod 122 drives the pressure plate 123 to extend, pressing and shaping the material in the cavity 110. After pressing and absorption by the subsequent inner cavity 114 are completed, the servo motor 113 rotates the mold wheel 111 by another angle, rotating the cavity 110 containing the pressed cotton core to the conveyor belt 112. At this time, the straight pipe 126 communicating with this cavity 110 is rotated to the lower part of the fixed ring 109, and under the separation action of the sliding stopper plate 128...At this point, the vacuum chamber in the lower straight pipe 126 and the connected vacuum chamber 133 loses its suction force, allowing the formed cotton core in the cavity 110 to fall onto the conveyor belt 112 under gravity. During this process, the support chamber 135 in the middle of the conveyor belt 112 is connected through the connecting pipe 134, creating a negative pressure environment in the support chamber 135. This negative pressure allows the formed medical cotton core to be drawn out of the cavity 110 through the fine grooves on the conveyor belt 112, preventing material jamming and facilitating practical use. The stepper motor and drive roller at the end of the conveyor belt 112 drive the conveyor belt 112 to circulate, further conveying the cotton core and completing the medical cotton core export process.
