[0009] By adopting the above technical solution, the negative pressure component inside the blister tray generates negative pressure and transmits it to the blister slot through the negative pressure port; the negative pressure causes the lower plastic packaging plate to be attracted to the bottom of the blister slot to form an adsorption state; under the influence of the negative pressure, the lower plastic packaging plate will deform downward in the blister slot area; the deformed lower plastic packaging plate matches the contour of the blister slot, thereby forming a packaging slot suitable for product placement; in this process, the deformation of the lower plastic packaging plate presents instantaneous and uniform characteristics, which helps to ensure that the shape and size of the packaging slot remain consistent; through negative pressure adsorption, the lower plastic packaging plate can achieve a precise packaging slot shape during the molding process, thereby improving the matching degree of product packaging and reducing resource waste.

[0010] Preferably, a demolding assembly is provided in the accommodating cavity of the blister tray, and the demolding assembly includes a plurality of rotating shafts matching the blister grooves, a top rod rotatably arranged in the blister tray, and a through hole arranged at the center position of the bottom of the blister groove, the middle part of the top rod is rotatably arranged between the blister tray, a special-shaped rotating block is arranged at the center position of the top of the rotating shaft, the bottom of the top rod is located on the outside of the special-shaped rotating block, and the top of the special-shaped rotating block is movably arranged inside the through hole.

[0011] By adopting the above technical scheme, the demoulding component is composed of several parts such as a rotating shaft, a push rod and a through hole; the shape of the rotating shaft conforms to the blister slot and is designed to rotate freely in the blister tray; when the rotating shaft starts to rotate, the special-shaped rotating block on the top will laterally squeeze the bottom of the push rod; the design of this special-shaped rotating block ensures that there is enough contact surface between it and the push rod during the rotation process to promote effective force transmission; the push rod rotates around its central axis, causing its top to gradually rise and exceed the upper surface of the through hole; this process generates sufficient thrust to enable the packaging slot located directly above the through hole to be ejected from the blister slot and demoulding is successfully achieved; through this mechanical movement mode, a fast and continuous demoulding process is achieved, and the overall efficiency is significantly improved compared with manual operation or other complex demoulding technologies.

[0012] Preferably, the demolding assembly also includes a driving assembly, which includes an electric push rod arranged in the accommodating cavity and a gear fixed at the center position of the bottom of the rotating shaft. The output end of the electric push rod is connected to a cross bar, and a plurality of rows of racks are arranged on the cross bar. The plurality of rows of racks are arranged corresponding to the plurality of rows of blister grooves, and the racks are meshed with the gears.

[0013] By adopting the above technical solution, through the meshing of gears and racks, the synchronous driving of multiple rotating shafts can be accurately achieved, thereby improving the control efficiency of multiple demolding processes; this synchronous operation ensures the coordination and stability of the entire demolding system, and effectively reduces the problem of poor matching that may occur during individual demolding.

[0014] Preferably, the separation assembly comprises a support box, a rotatable rocker arm is provided inside the support box, a driving motor is provided on the rocker arm, and a winding wheel for winding up the protective film is connected to the output end of the driving motor.

[0017] By adopting the above technical solution, the lower resistance wheel on the bottom rod has a rotation function and applies pressure to the protective film; in the process of the protective film being wound up by the winding wheel, the pressure of the lower resistance wheel can keep the protective film in a certain tension state, thereby effectively avoiding repeated relaxation and adhesion of the film.

[0018] Preferably, the unloading assembly includes a mounting column, a crossbeam is fixedly mounted on the top of the mounting column, a plurality of rows of guide sleeves for storing cotton pads are arranged inside the crossbeam, the guide sleeves are connected from top to bottom, and a plurality of rows of guide sleeves are arranged corresponding to any row of blister grooves.

[0019] By adopting the above technical solution, the cotton pads are stacked vertically through the guide sleeve and fall naturally by gravity; under the action of gravity, each layer of cotton pads will shift downward layer by layer; as the packaging slot moves, the cotton pad that has just fallen into the blister slot will no longer occupy the bottom position of the guide sleeve, and the next layer of cotton pads will become the new bottom layer and continue to fall downward into the next packaging slot; this process is repeated continuously.

[0020] Preferably, the bottom of the guide sleeve is perpendicular to the blister groove, and the cross-sectional dimension of the blister groove is larger than the cross-sectional dimension of the guide sleeve.

[0021] By adopting the above technical solution, when the cotton pad at the bottom layer moves to the bottom of the guide sleeve under the action of gravity, it will smoothly fall into the blister groove.

[0023] By adopting the above technical solution, the cylinder drives the positioning plate to press down, so that the shaping block applies a certain pressure to the cotton pad below; when the positioning plate descends, the shaping block can apply pressure evenly, thereby compressing and shaping the fluffy cotton pad.

[0024] Preferably, the bottom of the shaping block is perpendicular to the blister groove, and the cross-sectional dimension of the blister groove is larger than the cross-sectional dimension of the shaping block.

[0025] By adopting the above technical solution, since the cross-sectional size of the blister groove is larger than that of the shaping block, the shaping block can smoothly pass through the blister groove without hindering the final placement of the cotton pad; after the cotton pad is pressurized by the shaping block, it can be stably placed in the packaging groove to achieve final shaping and fixation.

[0026] In summary, this application has the following beneficial effects: 1. The packaging system uses the driving component to achieve horizontal movement of the lower plastic packaging plate to ensure the guidance of the path during the packaging process; the separation component effectively prevents the protective film from sticking to ensure packaging quality; the unloading component accurately places the cotton pad, and the dust removal component removes the surface dust to keep the packaging clean; at the same time, the hot pressing component ensures the docking consistency of the upper and lower plastic packaging plates, and achieves a close fit by applying heat. This process optimizes the packaging efficiency and quality of the cotton pad.

[0027] 2. The negative pressure component inside the blister tray generates negative pressure and transmits it to the blister slot through the negative pressure port; the negative pressure causes the lower plastic packaging plate to be attracted to the bottom of the blister slot, forming an adsorption state; under the influence of the negative pressure, the lower plastic packaging plate will deform downward in the blister slot area; the deformed lower plastic packaging plate matches the contour of the blister slot, thereby forming a packaging slot suitable for product placement; in this process, the deformation of the lower plastic packaging plate presents instantaneous and uniform characteristics, which helps to ensure that the shape and size of the packaging slot remain consistent; through negative pressure adsorption, the lower plastic packaging plate can achieve a precise packaging slot shape during the molding process, thereby improving the matching degree of product packaging and reducing resource waste.

[0028] 3. The demoulding assembly consists of several parts, including a rotating shaft, a push rod and a through hole. The shape of the rotating shaft matches the blister slot and is designed to rotate freely in the blister tray. When the rotating shaft starts to rotate, the special-shaped rotating block on the top will squeeze the bottom of the push rod laterally. The design of this special-shaped rotating block ensures that there is enough contact surface between it and the push rod during the rotation process to promote effective force transmission. The push rod rotates around its central axis, causing its top to gradually rise and exceed the upper surface of the through hole. This process generates sufficient thrust to enable the packaging slot located directly above the through hole to be ejected from the blister slot and demould smoothly. Through this mechanical movement method, a fast and continuous demoulding process is achieved, and the overall efficiency is significantly improved compared to manual operation or other complex demoulding technologies.

Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0031] The present invention discloses a blister packaging device for cotton pads, such as Figure 1As shown, it includes a base 1, a long groove 2 is provided at the center of the base 1, a blister tray 3 and a driving member are provided in the groove 2 of the base 1, a lower plastic packaging plate 4 is movably provided above the blister tray 3 through the driving member, and the lower plastic packaging plate 4 forms a guide path inside the groove 2 through the driving member, and a separation component 5 for separating a protective film provided on the lower plastic packaging plate 4, a feeding component 6 for placing a cotton pad, a dust removal component 7 for dust removal and a guide column 8 are sequentially provided on the base 1 and along the guide path, and an upper driving component 1205 and a movable upper plastic packaging plate 9 are provided inside the guide column 8, wherein the upper driving component 1205 is used to drive the upper plastic packaging plate 9 and move it directly above the lower plastic packaging plate 4, and the upper plastic packaging plate 9 and the lower plastic packaging plate 4 are hot-pressed and formed by the hot-pressing component 10 provided in the guide column 8, and the packaging function of the cotton pad is realized.

[0032] like Figure 1 As shown, specifically, a long strip groove 2 is provided in the center of the base 1, in which a blister tray 3 and a driving member are embedded; the lower plastic packaging plate 4 is moved left and right by the driving member, thereby forming a guide path during the packaging process; during the packaging process, the main function of the separation component 5 is to separate the protective film from the lower plastic packaging plate 4 to prevent the protective film from sticking, thereby ensuring the packaging quality.

[0033] like Figure 1 As shown, once the separation is completed, the unloading component 6 accurately places the cotton pad onto the lower plastic packaging plate 4 to ensure that each cotton pad can be placed in a standardized manner; after placement, the dust on the surface of the cotton pad is removed by the dust removal component 7 to ensure the cleanliness of the packaging process; finally, the hot pressing component 10 in the guide column 8 is used to ensure the docking consistency and stability between the upper plastic packaging plate 9 and the lower plastic packaging plate 4; the upper driving component 1205 controls the movement of the upper plastic packaging plate 9, and the hot pressing component 10 applies the necessary heat between the upper and lower plastic packaging plates 4, and makes the two fit tightly through hot pressing, and finally completes the packaging of the cotton pad.

[0034] like Figure 2 As shown, a blister groove is provided at the bottom of the groove 2 of the blister tray 3, and two negative pressure ports 11 are symmetrically arranged inside the blister groove. The blister grooves are arranged in several rows inside the groove 2, and several rows of blister grooves are arranged along the length direction of the groove 2. A accommodating cavity is provided inside the blister tray 3, and a negative pressure component for generating negative pressure is provided in the accommodating cavity of the blister tray 3. The output end of the negative pressure component is connected to the negative pressure port 11, and the negative pressure generated inside the blister groove by the negative pressure component causes the lower plastic packaging plate 4 to deform downward at the position of the blister groove, and a packaging groove 13 matching the blister groove is formed on the lower plastic packaging plate 4.

[0035] like Figure 2As shown, the negative pressure component inside the blister tray 3 will generate negative pressure, and transmit the negative pressure to the inside of the blister slot through the negative pressure port 11; due to the effect of the negative pressure, the lower plastic packaging plate 4 is attracted to the bottom of the blister slot to form an adsorption state; under the influence of the negative pressure, the lower plastic packaging plate 4 will produce a downward deformation in the area of ​​the blister slot; after the lower plastic packaging plate 4 is attracted and deformed, it will match the contour of the blister slot to form a packaging slot 13 suitable for product placement; in this process, the formation process of the lower plastic packaging plate 4 is instantaneous and uniform, which helps to ensure the shape and size consistency of the packaging slot 13; by adsorbing the lower plastic packaging plate 4 with negative pressure, a precise shape of the packaging slot 13 can be obtained during the molding process, which improves the matching degree of product packaging and reduces waste.

[0036] like Figure 2 and Figure 3 As shown, a demoulding assembly 12 is provided in the accommodating cavity of the blister tray 3 , and the demoulding assembly 12 enables the lower plastic packaging plate 4 to quickly detach from the blister groove.

[0037] like Figure 3 and Figure 4 As shown, specifically, the demoulding component 12 includes a plurality of rotating shafts 1201 matching the blister grooves, a push rod 1202 rotatably arranged in the blister tray 3, and a through hole 1203 arranged at the center position of the bottom of the blister groove. The middle part of the push rod 1202 is rotatably arranged between the blister tray 3, and a special-shaped rotating block 1204 is arranged at the top center position of the rotating shaft 1201. The bottom of the push rod 1202 is located on the outside of the special-shaped rotating block 1204, and the top of the special-shaped rotating block 1204 is movably arranged inside the through hole 1203. Through the rotation of the rotating shaft 1201, the special-shaped rotating block 1204 at its top squeezes the bottom of the push rod 1202, so that the push rod 1202 rotates around its middle, so that the top of the push rod 1202 is higher than the upper surface of the through hole 1203, thereby realizing that the packaging groove 13 formed directly above the through hole 1203 is ejected from the blister groove.

[0038] like Figure 3 and Figure 4As shown, the demoulding component 12 is composed of a rotating shaft 1201, a push rod 1202 and a through hole 1203, wherein the rotating shaft 1201 matches the shape of the blister groove and is rotatably arranged in the blister tray 3; when the rotating shaft 1201 rotates, the special-shaped rotating block 1204 on the top will laterally squeeze the bottom of the push rod 1202; the design of the special-shaped rotating block 1204 can ensure sufficient contact surface and force transmission during rotation; the push rod 1202 rotates around its center, causing the top of the push rod 1202 to rise and exceed the upper surface of the through hole 1203; the rise of the top of the push rod 1202 generates sufficient force to eject the packaging groove 13 located directly above the through hole 1203 from the blister groove, thereby achieving the purpose of demoulding; a fast and continuous demoulding process is achieved by mechanical movement, and the efficiency is significantly improved compared with manual or other complex demoulding methods.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown, the use of the rotating shaft 1201 and the ejector pin 1202 can apply force evenly, avoiding damage or deformation of the molded product due to local excessive pressure, and improving the stability of demolding; the mechanized and automated design reduces the intervention of human operation and reduces the errors and inconsistencies that may occur in manual demolding.

[0040] like Figure 3 , Figure 4 and Figure 5 As shown, the demoulding component 12 also includes a driving component 1205, which includes an electric push rod 120501 arranged in the accommodating cavity and a gear 120502 fixed at the bottom center position of the rotating shaft 1201. The output end of the electric push rod 120501 is connected to a cross bar 120503, and a plurality of rows of racks 120504 are arranged on the cross bar 120503. The plurality of rows of racks 120504 are arranged corresponding to the plurality of rows of blister grooves, and the racks 120504 are meshingly connected with the gears 120502. Through the electric push rod 120501, the racks 120504 on the cross bar 120503 are displaced forward and backward, and the gears 120502 are driven to rotate forward and reverse, thereby realizing the synchronous driving of the plurality of rotating shafts 1201.

[0041] like Figure 3 , Figure 4 and Figure 5As shown, the driving component 1205 includes an electric push rod 120501 arranged in the accommodating cavity, and its output end is connected to a cross bar 120503, and a plurality of rows of racks 120504 are arranged on the cross bar 120503; when the electric push rod 120501 is working, the front and rear displacement of the output end causes the racks 120504 on the cross bar 120503 to slide along the anchoring direction; the movement of the racks 120504 causes the meshing gears 120502 to rotate forward and reverse, and the rotating gears 120502 drive the plurality of rotating shafts 1201 to rotate; the plurality of rows of racks 120504 correspond one by one to the blister grooves, and the front and rear displacement of the racks 120504 drives the synchronous rotation of the plurality of rotating shafts 1201 through the gears 120502; since all the racks 120504 are arranged along the same cross bar 120503, the synchronization of the rotating shafts 1201 is ensured.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, through the meshing of the gear 120502 and the rack 120504, the synchronous driving of multiple rotating shafts 1201 can be accurately achieved, thereby improving the control efficiency of multiple demoulding processes; the synchronous operation can ensure the coordination and stability of the entire demoulding system, and reduce the poor matching problems that may occur during separate demoulding; and the introduction of the electric push rod 120501 makes the entire demoulding process more automated, reduces the need for manual operation, and improves production efficiency; after realizing automated control, it can be better integrated into modern production lines and robot systems.

[0043] like Figure 6 As shown, the separation component 5 includes a support box 501, a rotatable rocker arm 502 is provided inside the support box 501, a driving motor is provided on the rocker arm 502, and the output end of the driving motor is connected to a winding wheel 503 for winding up the protective film, the rocker arm 502 inside the support box 501 is driven to rotate by the driving motor, and the output end of the motor is connected to the winding wheel 503, so as to realize the winding of the protective film; a bottom rod is provided at the bottom of the support box 501, and a rotatable lower push wheel 504 is provided on the bottom rod, and the lower push wheel 504 on the bottom rod can rotate and press on the protective film; when the protective film is wound up by the winding wheel 503, the pressure of the lower push wheel 504 keeps the protective film in a certain tension state, thereby avoiding repeated relaxation and adhesion of the film.

[0044] like Figure 6 As shown, when the winding wheel 503 rotates, one end of the protective film fixed thereon is gradually rolled up, and this process causes the other end of the protective film to be gradually pulled away from the lower plastic packaging plate 4; due to the support of the lower abutment wheel 504, the moving path of the protective film remains smooth, ensuring the one-time separation effect of the protective film; by effectively separating the protective film, it is prevented from adhering to the lower plastic packaging plate 4, thereby ensuring the integrity and aesthetics of the product packaging.

[0045] like Figure 6 As shown, the unloading component 6 includes a mounting column 601, a crossbeam 602 is fixedly mounted on the top of the mounting column 601, and a plurality of rows of guide sleeves 603 for storing cotton pads are arranged inside the crossbeam 602. The guide sleeves 603 are connected from top to bottom, and a plurality of rows of guide sleeves 603 are arranged corresponding to any row of blister grooves, and the bottom of the guide sleeve 603 is vertically oriented toward the blister groove, and the cross-sectional dimension of the blister groove is larger than the cross-sectional dimension of the guide sleeve 603.

[0046] like Figure 6 As shown, the cotton pads are stacked vertically together through the guide sleeve 603 and fall naturally by gravity; each layer of cotton pads will shift downward layer by layer under the action of gravity; the bottom of the guide sleeve 603 is vertically facing the blister groove, and the cross-sectional size of the blister groove is larger than the cross-sectional size of the guide sleeve 603; when the bottom layer of cotton pads moves to the bottom of the guide sleeve 603 under the action of gravity, it will smoothly fall into the blister groove; as the packaging groove 13 moves, the cotton pad that has just fallen into the blister groove will no longer occupy the bottom position of the guide sleeve 603, and the next layer of cotton pads will become the new bottom layer and continue to fall downward into another packaging groove 13; this process is repeated continuously.

[0047] like Figure 6 As shown, this design can realize automatic unloading, reduce manual operations and improve overall work efficiency; through precise guidance and logistics systems, it can ensure that there is no unnecessary waste of cotton pads, while improving the neatness and quality of the finished products.

[0048] like Figure 6 As shown, in summary, the blanking component 6 utilizes gravity and reasonable design principles, which not only improves efficiency but also reduces losses, thus providing convenience for the production and packaging of cotton pads.

[0049] like Figure 6 As shown, an extension plate 604 is fixedly installed on the mounting column 601, and a cylinder is arranged inside the extension plate 604. The bottom output of the cylinder is connected to a positioning plate 605. A plurality of rows of shaping blocks 606 are arranged at the bottom of the positioning plate 605. The plurality of rows of shaping blocks 606 are arranged corresponding to any row of blister grooves. The bottom of the shaping block 606 is vertically facing the blister groove, and the cross-sectional dimension of the blister groove is larger than the cross-sectional dimension of the shaping block 606. The cylinder drives the positioning plate 605 to press downward, so that the shaping block 606 applies a certain pressure to the cotton pad below; when the positioning plate 605 descends, the shaping block 606 can apply pressure evenly, thereby compressing and shaping the fluffy cotton pad; since the cross-sectional dimension of the blister groove is larger than the cross-sectional dimension of the shaping block 606, the shaping block 606 can smoothly pass through the blister groove without hindering the final placement of the cotton pad; after the cotton pad is pressed by the shaping block 606, it can be stably placed in the packaging groove 13 to achieve final shaping and fixation.

[0050] like Figure 6 As shown, the cylinder-driven automation system can efficiently apply uniform pressure to the fluffy cotton pad, ensuring that the shaping can be effectively completed every time and reducing the variability caused by human operation; since the design of the shaping block 606 corresponds to the setting of the blister groove, each cotton pad can maintain the same shape and size during the pressure application process, ensuring the consistency and standardization of the product.

[0051] Working principle: The lower plastic packaging plate 4 is moved left and right by the driving member to form a guide path during the packaging process; in this process, the main function of the separation component 5 is to separate the protective film from the lower plastic packaging plate 4, thereby preventing the adhesion of the protective film and ensuring the packaging quality. After the separation is completed, the negative pressure generated inside the blister groove by the negative pressure component causes the lower plastic packaging plate 4 to deform downward at the position of the blister groove, thereby forming a packaging groove 13 that matches the blister groove. This process uses the force of negative pressure to enable the lower plastic packaging plate 4 to accurately adapt to the shape of the blister groove, thereby improving the fit and stability of the packaging.

[0052] With the continuous movement of the lower plastic packaging plate 4, the unloading assembly 6 accurately delivers the cotton pads onto the lower plastic packaging plate 4 to ensure the standardized placement of each cotton pad.

[0053] After the placement, dust on the surface of the cotton pad is removed by the dust removal assembly 7 to ensure the cleanliness of the packaging process. Finally, the hot pressing assembly 10 is used in the guide column 8 to ensure the docking consistency and stability between the upper plastic packaging plate 9 and the lower plastic packaging plate 4.

[0054] The upper driving assembly 1205 controls the movement of the upper plastic packaging plate 9, while the hot pressing assembly 10 applies necessary heat between the upper and lower plastic packaging plates 4, and uses the hot pressing principle to make the two fit tightly together, and finally complete the packaging of the cotton pad. This series of operations cooperate with each other to form an efficient and stable packaging workflow.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
