TECHNICAL FIELD

However, patients themselves cannot easily use the syringe, and the pain and fear brought by the syringe further limit the patient's compliance. Drug loading and transdermal administration by microneedles (including needle heads with micron-level size) is one of the methods to solve the above problems. The microneedle transdermal administration method can achieve painless drug delivery, improve patient compliance and safety. At the same time, the microneedle can also realize quantitative and positioning delivery of drugs, and can achieve precise drug administration with good drug effect. In addition, the microneedle can also be used for skin pretreatment and has the ability to enhance skin permeability. Therefore, the microneedle has good clinical application prospect.

Preferably, the first production line also includes a carrier first material roll 102, which is typically located at the upstream end of the equipment and is used to load a roll of first carrier material 1021. The first carrier material 1021 is a sheet structure, typically a transparent, low-viscosity film. The first carrier material 1021 is used to support the target sheet 400 and to transport the target sheet 400. Further, the first production line also includes a waste discharge tape material roll 101, which is also located at the upstream end of the equipment and is used to load a roll of waste discharge tape material 1011.

[0130] Preferably, the first production line further includes at least one of a first waste collection mechanism 106, a second waste collection mechanism 108, a first pressing mechanism 103, and a feeding platform 104.

The first pressing mechanism 103 is located at the first pressing station (indicated by arrow C1), which is located upstream of the first cutting station. The feeding platform 104 is located downstream of the first pressing station and upstream of the first cutting station, and is used to carry the target material sheet 400.

[0131] The second production line includes a second die-cutting mechanism 204. Preferably, the second production line further includes an adhesive tape material roll 201 and a carrier second material roll 202; the adhesive tape material roll 201 is used to load the rolled adhesive tape material 2011; the carrier second material roll 202 is used to load the rolled second carrier material 2021; the second carrier material 2021 is used to support the adhesive tape material 2011, and further to support the laminated sheet material, and the second carrier material 2021 is also used to realize the conveying of the adhesive backing 600 and the sheet material. Preferably, the second production line further includes at least one of a second pressing mechanism 203, a third waste collection mechanism 205, and a fourth waste collection mechanism 206. The second pressing mechanism 203 is located at the second pressing station (the position indicated by arrow C4), which is located upstream of the second cutting station. The third waste collection mechanism 205 is located downstream of the second pressing mechanism 203. The fourth waste collection mechanism 206 is located downstream of the second die-cutting mechanism 204.

[0132] The equipment for preparing sheet-like components also includes a third production line, which operates in series with the first and second production lines. That is, the third production line produces sheet-like components based on the sheet structure 500 produced by the first production line and the adhesive backing 600 produced by the second production line. The sheet-like components referred to herein are the final products.

[0133] Preferably, the third production line further includes a second peeling mechanism 302. Preferably, the third production line further includes at least one of a third bonding mechanism 301 and a fifth waste collection mechanism 303. Further, the third production line may also include a feeding conveyor belt 304. The third bonding mechanism 301, as a preferred structure, is used to assist in the bonding of the sheet structure 500 and the adhesive backing 600 at the bonding station, resulting in better adhesion. Preferably, the third bonding mechanism 301 includes an air blowing mechanism 305, which blows air towards the second carrier material 2021 at the bonding station. The second peeling mechanism 302 is located at the second peeling station (the position indicated by arrow C7). The fifth waste collection mechanism 303 is located downstream of the second peeling mechanism 302 and connected to the second carrier material 2021.

[0134] It should be understood that at the bonding station, based on the speed and position of the sheet structure 500 transported from the first production line to the bonding station, and based on the speed and position of the adhesive backing 600 transported from the second production line to the bonding station, the sheet structure 500 and the adhesive backing 600 can be aligned and automatically bonded one-to-one at the bonding station, wherein the adhesive side of the adhesive backing 600 adheres to the sheet structure 500. It should also be understood that if the target material sheet 400 in this embodiment is a microneedle sheet, the microneedle sheet includes, but is not limited to, the preparation of eye masks, and can also be used to prepare other sheet-like microneedle products.

[0135] Furthermore, the equipment also includes a waste conveyor belt material conveying mechanism and a first carrier material conveying mechanism. (Reference) Figure 2 The waste discharge tape material conveying mechanism is responsible for continuously feeding the rolled waste discharge tape material 1011 along its length. The first carrier material conveying mechanism is arranged in parallel with the waste discharge tape material conveying mechanism and is responsible for continuously feeding the rolled first carrier material 1021 along its length. The discharged waste discharge tape material 1011 is usually located above the discharged first carrier material 1021. The waste discharge tape material 1011 is located upstream of the first cutting station. The width of the waste discharge tape material 1011 is smaller than the width of the first carrier material 1021. Both sides of the waste discharge tape material 1011 are adhesive and are used to adhere to at least one edge of the first carrier material 1021, and are also used to adhere to the waste material after the target object original sheet 400 is cut.

[0136] In a preferred embodiment of the present invention, the discharged waste discharge tape material 1011 and the discharged first carrier material 1021 are pressed together by a first pressing mechanism 103 at a first pressing station (the position indicated by arrow C1), so that the waste discharge tape material 1011 is pressed onto the first carrier material 1021. Further, at the first pressing station, the first pressing mechanism 103 presses the two independent strands of waste discharge tape material 1011 onto the two opposite edges of the first carrier material 1021, such as... Figure 2 As shown. Of course, in other embodiments, the first pressing mechanism 103 can press the single strand of waste discharge tape material 1011 onto one side edge of the first carrier material 1021 at the first pressing station.

[0137] Continue to refer to Figure 1After the waste discharge tape material 1011 is pressed together with the first carrier material 1021, it continues to be conveyed downstream by the first carrier material 1021. Then, preferably at the discharge platform 104, the first carrier material 1021 is joined (including bonded) with the target object sheet 400, so that the target object sheet 400 is supported and conveyed by the first carrier material 1021. Preferably, the target object sheet 400 covers the first carrier material 1021 and the waste discharge tape material 1011. After the first carrier material 1021 joins the target object sheet 400, it continues to be conveyed downstream and moves the target object sheet 400 to the first cutting station (the position indicated by arrow C2). At the first cutting station, the first die-cutting mechanism 105 cuts the target object sheet 400 on the first carrier material 1021 to form multiple sheet structures 500 with predetermined shapes and sizes. The multiple sheet structures 500 are still attached to the first carrier material 1021, and it must be ensured that the first carrier material 1021 is not cut during the cutting process. Furthermore, the waste material after cutting the original target sheet 400 adheres to the waste discharge tape material 1011, and the first waste collection mechanism 106 rolls up and recycles the waste material after cutting the original target sheet 400 and the waste discharge tape material 1011 together. That is, the waste discharge tape material 1011, which was originally adhered to the first carrier material 1021, detaches from the first carrier material 1021 and adheres to the waste material of the original target sheet 400 for recycling. The multiple sheet-like structures 500 formed after cutting continue to be conveyed by the first carrier material 1021 to the first peeling station (the position indicated by arrow C3). At the first peeling station, the first peeling mechanism 107 peels (or separates) the first carrier material 1021 and the sheet-like structures 500. All the peeled sheet-like structures 500 are conveyed to the bonding station (the position indicated by arrow C6), and the peeled first carrier material 1021 is preferably rolled up and recycled by the second waste collection mechanism 108.

[0138] Furthermore, the second production line also includes a second carrier material conveying mechanism and an adhesive tape material conveying mechanism. The adhesive tape material conveying mechanism is responsible for continuously feeding the roll of adhesive tape material 2011 along its length. The second carrier material conveying mechanism is arranged in parallel with the adhesive tape material conveying mechanism and is responsible for continuously feeding the roll of second carrier material 2021 along its length. The fed adhesive tape material 2011 is located below or above the fed second carrier material 2021, usually below. One side of the adhesive tape material 2011 is adhesive and used to locally adhere the sheet-like structure 500, which is supported and conveyed by the second carrier material 2021.

[0139] The delivered adhesive tape material 2011 and the delivered second carrier material 2021 are preferably pressed together by the second pressing mechanism 203 at the second bonding station (the position indicated by arrow C4), so that the adhesive tape material 2011 is pressed onto the second carrier material 2021, and at the same time, the release paper on the adhesive tape material 2011 is peeled off at the second bonding station, and preferably the release paper is recovered by the third waste collection mechanism 205. The second pressing mechanism 203 is used to press the adhesive tape material 2011 onto the second carrier material 2021 at the second pressing station.

[0140] The adhesive tape material 2011 continues to be conveyed downstream through the second carrier material 2021 to the second cutting station (indicated by arrow C5). The second die-cutting mechanism 204 cuts the adhesive tape material 2011 on the second carrier material 2021, forming multiple adhesive backing sheets 600 with predetermined shapes and sizes. These multiple adhesive backing sheets 600 remain bonded to the second carrier material 2021. The waste material after cutting the adhesive tape material 2011 is preferably recycled by the fourth waste collection mechanism 206. The multiple adhesive backing sheets 600 formed after cutting continue to be conveyed by the second carrier material 2021 to the bonding station.

[0141] At the bonding station (approximately indicated by arrow C6), multiple sheet structures 500 and multiple adhesive backing sheets 600 are adhered and bonded together to obtain multiple sheet-like parts. In this embodiment, a portion of the adhesive side of each adhesive backing sheet 600 is bonded to a localized area of ​​the sheet structure 500, such as... Figure 6 As shown, the bonded sheet structure 500 and the adhesive backing 600 are still supported by the second carrier material 2021 and transported downstream.

[0142] To ensure better adhesion between the adhesive backing 600 and the sheet structure 500, an air blowing mechanism 305 preferably blows air towards the second carrier material 2021 at the bonding station. The angle between the blowing direction and the horizontal direction is (0°, 90°), more preferably 30° to 90°, and even more preferably 90°. The air blowing mechanism 305 preferably includes a porous air knife, with a preferred airflow rate of 100–200 L / min and an air pressure of 0.4–0.7 MPa. The airflow is adjustable. The porous air knife forms a row of micro-airflow jets with a pore diameter of 0.5–3 mm and a width greater than the width of the second carrier material 2021.

[0143] like Figure 1As shown, in a preferred embodiment of the invention, multiple sheet-like components continue to be conveyed via the second carrier material 2021 and arrive at the second stripping station. At the second stripping station (approximately indicated by arrow C7), the second stripping mechanism 302 strips (or separates) the second carrier material 2021 and the multiple sheet-like components. The stripped sheet-like components can then be conveyed onto the unloading conveyor belt 304. The stripped second carrier material 2021 is preferably recycled by the fifth waste collection mechanism 303.

[0144] It should be understood that the first and second production lines continuously produce sheet structures 500 and adhesive backing sheets 600 sequentially, and thus the third production line also continuously produces sheet components sequentially. Specifically, for the first production line, batches of target material sheets 400 are sequentially and orderly fed, die-cut, and then the sheet structures 500 are peeled off and enter the third production line. For the second production line, batches of adhesive tape material 2011 are sequentially and orderly fed, pressed, separated from the release paper, and die-cut to obtain adhesive backing sheets 600, which then enter the third production line. For the third production line, the sheet structures 500 and adhesive backing sheets 600 are continuously bonded together, and can be further peeled off from the second carrier material 2021. It should also be understood that the second carrier material 2021 and the first carrier material 2021 are actually the same material.

[0145] The equipment for preparing sheet-like components of the present invention enables continuous and large-scale production of sheet-like components, improving production efficiency and reducing production costs. Particularly preferred is the equipment for preparing sheet-like components, which also enables waste recycling, effectively saving energy and reducing production costs.

[0146] refer to Figure 1 The first pressing mechanism 103 may include a first pressure roller 1031 and a pressing first support roller 1032. The first pressure roller 1031 is positioned above the first carrier material 1021, and the pressing first support roller 1032 is positioned below the first carrier material 1021. Waste discharge tape material 1011 is located between the first carrier material 1021 and the first pressure roller 1031. The first pressure roller 1031 is used to press the waste discharge tape material 1011 onto the first carrier material 1021; the pressing first support roller 1032 supports the first carrier material 1021 to ensure the stability of the pressing process. The first pressure roller 1031 is typically a rubber roller; the pressing first support roller 1032 is a metal roller, such as a stainless steel roller. Both the first pressure roller 1031 and the pressing first support roller 1032 are rotatable. The position of the pressing first support roller 1032 corresponds to the position of the first pressure roller 1031.

[0147] In this embodiment, the feeding platform 104 is an optional structure. The target material sheet 400 can be pre-set on the feeding platform 104, such as partially placed on the feeding platform 104 and partially placed directly on the first carrier material 1021. Optionally, the first carrier material 1021 can be combined with the target material sheet 400 over the feeding platform 104, or it can be combined with the target material sheet 400 over the feeding platform 104.

[0148] Furthermore, the first die-cutting mechanism 105 includes a first circular blade 1051 capable of rotation. The outer surface of the first circular blade 1051 is provided with first blades, the shape of which is the same as that of the sheet structure 500. The number of first blades is the same as the number of sheet structures 500. At the first cutting station, the first circular blade 1051 is driven to rotate. The axis of rotation of the first circular blade 1051 is horizontally arranged and perpendicular to the conveying direction of the target sheet 400. Figure 1 From the perspective of the first circular cutter 1051, the axis of rotation of the first circular cutter 1051 is perpendicular to the paper surface; thus, the first circular cutter 1051 cuts the target sheet 400 on the moving first carrier material 1021 through its rotation, and obtains the sheet structure 500.

[0149] In this embodiment, the rotational speed of the first circular cutter 1051 is related to the moving speed of the first carrier material 1021. The moving speed of the first carrier material 1021 is the product of the rotational speed of the first circular cutter 1051 and the circumference of the first circular cutter 1051. Therefore, the moving speed of the first carrier material 1021 can be adaptively adjusted according to the diameter of the first circular cutter 1051, thereby ensuring that the first circular cutter 1051 can continuously cut the target object 400 and ensuring that the first carrier material 1021 is not cut during cutting. Preferably, the rotational speed of the first circular cutter 1051 is (0, 100 r / min) and the moving speed of the first carrier material 1021 is (0, 60 m / min).

[0150] Preferably, the first die-cutting mechanism 105 further includes a first die-cutting support roller 1052, which is disposed corresponding to the first circular cutter 1051. The first die-cutting support roller 1052 and the first circular cutter 1051 are respectively disposed on opposite sides of the first carrier material 1021. The first die-cutting support roller 1052 supports the first carrier material 1021 to facilitate die-cutting (or cutting), ensuring the stability of die-cutting, and the first die-cutting support roller 1052 is rotatable. More preferably, the first die-cutting mechanism 105 further includes a second die-cutting support roller 1053, which is disposed upstream of the first die-cutting support roller 1052. The first die-cutting support roller 1052 and the second die-cutting support roller 1053 are disposed on the same side of the first carrier material 1021, and their positions are usually relatively close. The second die-cutting support roller 1053 can further support the first carrier material 1021 to further provide die-cutting support force and further ensure the stability of die-cutting. The second die-cutting support roller 1053 is also rotatable. It should be understood that the pressing first support roller 1032, the die-cutting second support roller 1053 and the die-cutting first support roller 1052 can all be driven to rotate by gears. These support rollers can also realize the transmission of the first carrier material 1021, and these support rollers are preferably metal rollers, such as stainless steel rollers.

[0151] The first die-cutting mechanism 105 preferably further includes a rotatable second pressure roller 1054. The second pressure roller 1054 and the die-cutting second support roller 1053 are respectively disposed on opposite sides of the first carrier material 1021. The positions of the second pressure roller 1054 and the die-cutting second support roller 1053 correspond. Thus, the second pressure roller 1054 presses against the target material sheet 400, such as pressing against the non-needle area of ​​the microneedle sheet, so that the target material sheet 400 and the first carrier material 1021 are better bonded. The second pressure roller 1054 is usually a rubber roller.

[0152] The first waste collection mechanism 106 may include a first waste collection roll to collect waste materials cut from the target original sheet 400 and waste discharge tape material 1011.

[0153] like Figure 4aAs shown, the first peeling mechanism 107 includes a first peeling blade 1071, which has a first side and a second side. The first side and the second side of the first peeling blade 1071 form a first included angle θ1, which is less than or equal to 30°. The first peeling blade 1071 is used to press against the first carrier material 1021 on the side of the first carrier material 1021 facing away from the sheet structure 500 through its first side and second side, and to cause the first carrier material 1021 to change from a horizontal extension direction to a downward inclined extension direction at the first peeling blade 1071. That is, the first carrier material 1021 is formed into two parts with different extension directions by the first peeling blade 1071. The two parts of the first carrier material 1021 are a first horizontal part 10211 and a first inclined part 10212. The first horizontal part 10211 extends in a horizontal direction, and the first inclined part 10212 extends downward in an inclined direction relative to the direction of gravity.

[0154] like Figure 4b As shown, the two portions of the first carrier material 1021 form a third included angle α1 on the side opposite to the first peeling blade 1071, and the angle α1 is greater than or equal to 330°. At the first peeling station, the first peeling blade 1071 changes the conveying direction of the first carrier material 1021, causing the first carrier material 1021 to make a large turn at the first peeling blade 1071, thereby peeling the first carrier material 1021 from the sheet structure 500. This application does not limit the shape of the first peeling blade 1071; for example, it is not limited to a triangle but can also be trapezoidal.

[0155] The second waste collection mechanism 108 may include a second waste collection reel to collect the stripped first carrier material 1021 for reuse.

[0156] Continue to refer to Figure 1 The first production line preferably further includes a first tensioning mechanism 109, located downstream of the first die-cutting mechanism 105, for tensioning the first carrier material 1021. The first tensioning mechanism 109 may include a first tensioning roller 1091 and a second tensioning roller 1092, such as located upstream of the second waste collection mechanism 108. The first tensioning roller 1091 and the second tensioning roller 1092 are located on opposite sides of the first carrier material 1021 and press against it. The first tensioning roller 1091 may be a metal roller, such as a stainless steel roller, and the second tensioning roller 1092 may be a rubber roller. Both the first tensioning roller 1091 and the second tensioning roller 1092 are rotatable and can be driven by gears. The position and number of tensioning rollers in the first tensioning mechanism 109 are not limited. Furthermore, in addition to tensioning, the tensioning rollers can also convey the first carrier material 1021.

[0157] The second pressing mechanism 203 may include a second pressure roller 2031 and a pressing second support roller 2032. The second pressure roller 2031 is used to press the adhesive tape material 2011 onto the second carrier material 2021. The pressing second support roller 2032 is used to support the side of the second carrier material 2021 away from the adhesive tape material 2011. The position of the pressing second support roller 2032 corresponds to the position of the second pressure roller 2031. At the second pressing station, the second pressure roller 2031 and the pressing second support roller 2032 cooperate to press the adhesive tape material 2011 and the first carrier material 1021 together. The second pressure roller 2031 is typically a rubber roller, and the pressing second support roller 2032 is a metal roller, such as a stainless steel roller. Both the second pressure roller 2031 and the pressing second support roller 2032 are rotatable and can also convey the second carrier material 2021.

[0158] The second die-cutting mechanism 204 includes a rotatable second circular blade 2041. A second blade is provided on the outer surface of the second circular blade 2041, and the shape of the second blade is the same as that of the adhesive tape 600. The number of second blades is the same as the number of adhesive tapes 600. By driving the second circular blade 2041 to rotate at the second cutting station, the rotation axis of the second circular blade 2041 is horizontally arranged and perpendicular to the conveying direction of the adhesive tape 2011, such as from... Figure 1 From the perspective of the second circular cutter 2041, the axis of rotation of the second circular cutter 2041 is perpendicular to the paper surface; thus, by rotating the second circular cutter 2041, the adhesive tape material 2011 on the moving second carrier material 2021 is cut into the required adhesive backing 600.

[0159] In this embodiment, the rotational speed of the second circular cutter 2041 is related to the moving speed of the second carrier material 2021. The moving speed of the second carrier material 2021 is the product of the rotational speed of the second circular cutter 2041 and the circumference of the second circular cutter 2041. Therefore, the moving speed of the second carrier material 2021 can be adaptively adjusted according to the diameter of the second circular cutter 2041, thereby ensuring that the second circular cutter 2041 can continuously cut the adhesive tape material 2011, and ensuring that the second carrier material 2021 is not cut during cutting. Preferably, the rotational speed of the second circular cutter 2041 is (0, 100 r / min), and the moving speed of the second carrier material 2021 is (0, 60 m / min).

[0160] Preferably, the first circular blade 1051 and the second circular blade 2041 rotate at the same speed. Preferably, the first carrier material 1021 and the second carrier material 2021 move at the same speed to effectively ensure that the sheet structure 500 can be bonded to the adhesive backing 600 at the bonding station.

[0161] The second die-cutting mechanism 204 preferably further includes a second die-cutting support roller 2042, which corresponds to the position of the second circular cutter 2041. The second circular cutter 2041 and the second die-cutting support roller 2042 are respectively disposed on opposite sides of the second carrier material 2021. The second die-cutting support roller 2042 supports the second carrier material 2021 to facilitate die-cutting or cutting and ensure the stability of the cutting of the adhesive tape material 2011. The second die-cutting support roller 2042 can also rotate, and in addition to providing support force, it can also convey the second carrier material 2021. The second die-cutting support roller 2042 is preferably a metal roller, and more preferably a stainless steel roller.

[0162] The third waste collection mechanism 205 may include a third waste collection roll for collecting release paper peeled off from the adhesive tape material 2011. The fourth waste collection mechanism 206 may include a fourth waste collection roll for collecting waste material after cutting the adhesive tape material 2011.

[0163] like Figure 5a As shown, the second peeling mechanism 302 may include a second peeling blade 3021. The second peeling blade 3021 has a first side and a second side, and the first side and the second side of the second peeling blade 3021 form a second included angle θ2, the angle of the second included angle θ2 being less than or equal to 30°. The second peeling blade 3021 is used to press against the second carrier material 2021 on the side of the second carrier material 2021 away from the sheet material through its first side and second side, and to cause the second carrier material 2021 to form a change from a horizontal extension direction to a downward inclined extension direction at the second peeling blade 3021, that is, the second carrier material 2021 forms two parts with different extension directions through the second peeling blade 3021. The two parts of the second carrier material 2021 are a second horizontal part 20211 and a second inclined part 20212. The second horizontal part 20211 extends in a horizontal direction, and the second inclined part 20212 extends downward in an inclined direction relative to the direction of gravity.

[0164] like Figure 5b As shown, the two portions of the second carrier material 2021 form a fourth included angle α2 on the side opposite to the second peeling blade 3021, and the angle α2 is greater than or equal to 330°. At the second peeling station, the conveying direction of the second carrier material 2021 is changed by the second peeling blade 3021, causing the second carrier material 2021 to make a large turn at the second peeling blade 3021, thereby peeling the second carrier material 2021 from the sheet material. This application does not limit the shape of the second peeling blade 3021; ​​for example, it is not limited to a triangle but can also be trapezoidal.

[0165] The fifth waste collection mechanism 303 may include a fifth waste collection reel to collect the second carrier material 2021 stripped by the second stripping blade 3021.

[0166] The third production line also includes a second tensioning mechanism 306, located downstream of the second peeling mechanism 302, for tensioning the second carrier material 2021. Further, the second tensioning mechanism 306 includes a third tensioning roller 3061 and a fourth tensioning roller 3062, positioned upstream of the fifth waste collection mechanism 303. The third tensioning roller 3061 and the fourth tensioning roller 3062 are positioned on opposite sides of the second carrier material 2021 and press against it. The third tensioning roller 3061 can be a metal roller, such as a stainless steel roller, and is used for tensioning, conveying, and supporting the second carrier material 2021; the fourth tensioning roller 3062 is typically a rubber roller, used for both tensioning and conveying the second carrier material 2021. Both the third tensioning roller 3061 and the fourth tensioning roller 3062 are rotatable and can be driven by gears to ensure the stability of the secondary peeling process. The position and number of tensioning rollers in the second tensioning mechanism 306 are not required.

[0167] like Figure 4a As shown, the air blowing mechanism 305 may include a porous air knife 3051, which blows air at the position where the adhesive backing 700 and the sheet material 500 are joined. Preferably, the position of the air blowing mechanism 305 can be adjusted to change the air blowing position of the porous air knife 3051. For example, the air blowing mechanism 305 can move up and down and / or horizontally. In addition, there may be multiple air blowing mechanisms 305, which can blow air upstream of the first peeling station to firmly bond and flatten the sheet structure 500 with the first carrier material 1021, and can also blow air at the bonding station to firmly bond and flatten the sheet structure 500 with the adhesive backing 600.

[0168] Further preferably, the device also includes a bonding position detection device 307, used to identify the bonding state of the sheet material at the bonding station.

Preferably, the equipment for preparing sheet-like materials further includes a controller communicatively connected to the bonding position adjustment device 308.
