Abstract

An artificial skin patch manufacturing machine includes a machine body, one side of which has a mounting surface for mounting a feeding mechanism, a hot pressing mechanism, an artificial skin cutting mechanism and a recycling mechanism. The hot pressing mechanism has a first module and a second module, and a heating unit is respectively disposed inside the first module and the second module. The first module and the second module can hot press an artificial skin layer, so that the artificial skin layer has at least one depressed portion. After the artificial skin layer is cut into an artificial skin unit by the artificial skin cutting mechanism, the depressed portion is located at the edge of the artificial skin unit. When the artificial skin unit is attached to the skin, the depression prevents the artificial skin unit from having obvious protruding edges, and the artificial skin unit fits the skin more naturally.

Description

Artificial skin patch manufacturing machine

The present invention relates to an artificial skin patch manufacturing machine, which is a production line for continuously manufacturing an artificial skin patch.

With the development of science and technology, medical technology is constantly innovating. Artificial skin has the effects of being breathable, waterproof and helping healing. It is used to protect wounds to prevent them from being contaminated again. Artificial skin is generally made into small unit patches (hereinafter referred to as artificial skin patches). During manufacturing, the convenience and high efficiency of automated equipment are used to enable artificial skin patches to be mass-produced.

The production of artificial skin patches is completed by passing the entire strip through appropriate cutting, packaging, hot pressing, and waste recycling. Among them, the cutting method is usually to pass the strip through a roller with multiple blades (commonly known as a roller), that is, to cut small units corresponding to the blade shape on the strip, and each small unit can be used as a protective patch for different purposes (such as heel patches or acne patches, etc.). However, due to the thickness of artificial skin patches, when the small unit is attached to the skin, it has a clear protruding edge, which is not only visually unnatural, but also more likely to be removed by external force.

Next, the means of hot pressing is usually to pass the material strip through the hot pressing module for hot pressing, and stop conveying before the hot pressing is completed. This causes intermittent pauses in the manufacturing line and affects the stability of the tension of the material strip, increasing the defective rate of finished products and increasing the manufacturing time.

In addition, when the material strip is cut into small units, the unused material strip outside the small unit becomes waste. Because the structural strength of the waste material is insufficient, if too much tension is applied to the waste material during reeling, it is very easy to break, forcing the manufacturing line to be interrupted.

The artificial skin patch manufacturing machine of the present invention mainly provides a heat pressing mechanism, which can pre-heat press the artificial leather strip before cutting. The surface of the artificial leather strip after heat pressing has a surface shape of varying thickness, and the edge thickness of the artificial leather strip after being cut into artificial skin patches is thinner. In this way, when the artificial skin patch is attached to the skin, there will be no obvious protruding edges, and it can fit the skin more naturally and is less likely to fall off due to poking.

In addition, the artificial skin patch manufacturing machine of the present invention also provides a recycling mechanism, which has a sensing roller and a sensor for sensing the breakage of waste materials. The sensor can receive a sensing signal when the waste material breaks, so that the operation can be stopped immediately, further achieving safety monitoring of the production line.

Other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings.

Please refer to Figure 1. In this embodiment, the manufacturing machine includes a machine body 1, a feeding mechanism 2, a substrate cutting mechanism 3, a hot pressing mechanism 4, an artificial skin cutting mechanism 5 and a recycling mechanism 6. The machine body 1 has a mounting surface 11, on which the feeding mechanism 2, the substrate cutting mechanism 3, the hot pressing mechanism 4, the artificial skin cutting mechanism 5 and the recycling mechanism 6 are respectively installed. Through the above mechanisms, a production line is constructed to continuously process an artificial leather strip 7 into an artificial skin patch.

Please refer to Figure 2. It should be noted that the artificial leather belt 7 has an artificial leather layer 71 and a base layer 72. In practice, the material of the artificial leather layer 71 is artificial skin, which is sticky. Therefore, the artificial leather layer 71 can be adhered to the base layer 72 by its own stickiness. When in use, the artificial leather layer 71 can also be easily torn off from the base layer 72. In addition, the material of the base layer 72 is polyethylene terephthalate, commonly known as PET (Polyethylene terephthalate). In other embodiments, the base layer 72 can also be paper, and this embodiment is not limited to this.

Please refer to Figure 1 again. In this embodiment, the feeding mechanism 2 has at least one feeding roller 21 and at least one conveying pulley 22. The feeding roller 21 and the conveying pulley 22 are both installed on the mounting surface 11. In practice, the mounting surface 11 generally refers to the side where the artificial leather belt 7 is processed. Each feeding roller 21 is used to convey the unprocessed artificial leather belt 7 to the substrate cutting mechanism 3 to start the subsequent processing operation. A conveying pulley 22 is provided between the substrate cutting mechanism 3 and the hot pressing mechanism 4, and a conveying pulley 22 is also provided between the hot pressing mechanism 4 and the artificial leather cutting mechanism 5.

Please refer to FIG. 3. In this embodiment, the substrate cutting mechanism 3 has a substrate cutting wheel 31 and a substrate cutting anvil wheel 32. The substrate cutting wheel 31 and the substrate cutting anvil wheel 32 are both mounted on the mounting surface 11. The surface of the substrate cutting wheel 31 has at least one annular substrate cutting blade 311. The substrate cutting blade 311 is arranged along the circumferential surface of the substrate cutting wheel 31, and the substrate cutting blade 311 and the substrate cutting wheel 31 are integrally formed. The substrate cutting wheel 31 and the substrate cutting anvil wheel 32 are arranged adjacent to each other. There is a first spacing D1 between the substrate cutting blade 311 and the substrate cutting anvil wheel 32. The first spacing D1 is slightly less than or equal to the thickness of the artificial skin layer 71 (the artificial skin layer 71 is shown in FIG. 2).

Please refer to Figures 4 and 5. In this embodiment, when the artificial leather material belt 7 is transported to the substrate cutting mechanism 3, the substrate layer 72 faces the substrate cutting wheel 31, and the artificial leather layer 71 abuts against the substrate cutting anvil wheel 32. When the substrate cutting wheel 31 and the substrate cutting anvil wheel 32 are in operation, the rotation directions of the two are mirror-image rotations. In simpler terms, the substrate cutting wheel 31 rotates clockwise along the circumference, and the substrate cutting anvil wheel 32 rotates counterclockwise along the circumference. The artificial leather material belt 7 continuously passes through the first spacing D1 between the substrate cutting blade 311 and the substrate cutting anvil wheel 32. Since the substrate layer 72 faces the substrate cutting wheel 31, the substrate cutting blade 311 can cut the substrate layer 72 that passes continuously. Since the first distance D1 between the substrate cutting blade 311 and the substrate cutting anvil wheel 32 is slightly smaller than or equal to the thickness of the artificial leather layer 71, the artificial leather tape 7 can ensure that the substrate layer 72 is completely cut out of the substrate cutting portion 721 when passing through the first distance D1. The substrate cutting portion 721 can be completely cut or incompletely cut. The cutting of the substrate layer 72 is used to slit the substrate layer 72. After the slit, the artificial leather tape 7 is then transported to the hot pressing mechanism 4 to continue the subsequent processing operation.

Please refer to FIG. 6 . In this embodiment, the hot pressing mechanism 4 has a horizontal displacement device 41, a first mold block 42, a second mold block 43, two heating units 44 and a vertical displacement device 45. The horizontal displacement device 41 is installed on the mounting surface 11, and the first mold block 42 and the second mold block 43 are arranged on the horizontal displacement device 41. The first mold block 42 has a pressing surface 421, and the second mold block 43 has a pressing corresponding plane 431. The pressing surface 421 corresponds to the upper side of the pressing corresponding plane 431. A heating unit 44 is disposed inside the first module 42 and the second module 43 respectively. The heating unit 44 has a plurality of heating tubes 441. The heating tubes 441 are electric heating tubes. A vertical displacement device 45 is disposed above the first module 42.

Please refer to Figures 7 and 8. In this embodiment, the horizontal displacement device 41 achieves displacement through a connecting rod structure. The connecting rod structure includes a driving wheel 411, a connecting rod 412, a displacement base 413 and at least one displacement slide 414. The displacement slide 414 is a horizontal track. The two ends of the connecting rod 412 are pivoted on the driving wheel 411 and the displacement base 413 respectively, and the displacement base 413 is mounted on the displacement slide 414. The first module 42 and the second module 43 are arranged on the displacement base 413. The driving wheel 411 can be driven by a motor (not shown) to rotate, so that the connecting rod 412 at one end pivoted with the driving wheel 411 can rotate with the rotation of the driving wheel 411, and the connecting rod 412 at one end pivoted with the displacement base 413 is restricted by the displacement slide 414, further restricting the direction of rotation to the horizontal direction to achieve horizontal displacement. In addition, the vertical displacement device 45 is a cylinder, which realizes vertical displacement by pushing and pulling the cylinder in the vertical direction. In other embodiments, the horizontal displacement device 41 can also achieve the purpose of displacement through a cylinder or a gear, and the vertical displacement device 45 can also achieve the purpose of displacement through a connecting rod structure or a gear, etc. This embodiment is not limited to this.

Please refer to Figures 7, 8 and 9. In this embodiment, the horizontal displacement device 41 is used to drive the first module 42 and the second module 43 to perform horizontal displacement together. After the artificial leather strip 7 that has been stripped is transported to the hot pressing mechanism 4 through the transport pulley 22, the base material layer 72 faces the pressing corresponding plane 431 of the second module 43, and the artificial leather layer 71 faces the pressing surface 421 of the first module 42. First, the horizontal displacement device 41 moves to the first position P1, and at the same time, the vertical displacement device 45 pushes the first mold 42 downward, so that the artificial leather strip 7 is sandwiched between the first mold 42 and the second mold 43. At this time, the artificial leather layer 71 is hot-pressed by the pressing surface 421 on the first mold 42, so that the surface of the artificial leather layer 71 is formed into a shape corresponding to the pressing surface 421. During the hot pressing process, the horizontal displacement device 41 further moves to the second position P2, and then, the vertical displacement device 45 pulls the first mold 42 back upward, so that the first mold 42 and the second mold 43 release the artificial leather strip 7. After the hot pressing, the artificial leather strip 7 is then transported to the artificial leather cutting mechanism 5 to continue the subsequent processing operation. The horizontal displacement device 41 moves to the first position P1 again to perform heat pressing on the next section of artificial leather strip 7, and so on, continuously performing reciprocating operation.

Please refer to Figure 10. In this embodiment, the pressing surface 421 has a contact portion 422, a gentle slope forming portion 423 and a concave portion 424. In this way, after the artificial skin layer 71 is subjected to heat pressing, a depression portion 711 is heat pressed on the artificial skin layer 71 corresponding to the contact portion 422, a gentle slope portion 712 is heat pressed on the artificial skin layer 71 corresponding to the gentle slope forming portion 423, and a convex portion 713 is heat pressed on the artificial skin layer 71 corresponding to the concave portion 424. In this way, the depression portion 711, the gentle slope portion 712 and the convex portion 713 are formed on the artificial skin layer 71.

Please refer to Figure 11. In this embodiment, the artificial skin cutting mechanism 5 has an artificial skin cutting wheel 51 and an artificial skin cutting anvil wheel 52. The surface of the artificial skin cutting wheel 51 has a plurality of artificial skin cutting blades 511, and each artificial skin cutting blade 511 is evenly arranged along the circumference of the artificial skin cutting wheel 51. The artificial skin cutting blade 511 and the artificial skin cutting wheel 51 are integrally formed, and the artificial skin cutting blade 511 is set as a closed profile (for example but not limited to a geometric shape or an irregular shape, etc.). The artificial skin cutting wheel 51 and the artificial skin cutting anvil wheel 52 are arranged adjacent to each other, and there is a second distance D2 between the artificial skin cutting blade 511 and the artificial skin cutting anvil wheel 52. The second distance D2 is slightly less than or equal to the thickness of the substrate layer 72 (the substrate layer 72 is shown in Figure 2).

Please refer to Figures 12 and 13. In this embodiment, when the artificial leather material strip 7 is transported to the artificial leather cutting mechanism 5 by the transport pull wheel 22, its artificial leather layer 71 faces the artificial leather cutting wheel 51, and its base material layer 72 abuts against the artificial leather cutting anvil wheel 52. When the artificial leather cutting wheel 51 and the artificial leather cutting anvil wheel 52 are in operation, the rotation directions of the two are mirror image rotations relative to each other. In simpler terms, the artificial leather cutting wheel 51 rotates clockwise along the circumference, and the artificial leather cutting anvil wheel 52 rotates counterclockwise along the circumference, so that the artificial leather material strip 7 continuously passes through the second spacing D2 between the artificial leather cutting blade 511 and the artificial skin cutting anvil wheel 52. Since the artificial skin layer 71 faces the artificial skin cutting wheel 51, the artificial skin cutting blade 511 can cut the artificial skin layer 71 that passes continuously, and the artificial skin cutting blade 511 with a closed profile is used to cut the entire artificial skin layer 71 into a plurality of artificial skin units 714. Since the second distance D2 between the artificial skin cutting blade 511 and the artificial skin cutting anvil wheel 52 is slightly less than or equal to the thickness of the base layer 72, the artificial leather material strip 7 can ensure that the artificial skin layer 71 is completely cut into the artificial skin unit 714 when passing through the second distance D2. In practice, the closed profile of the artificial skin cutting blade 511 corresponds to the shape of the pressing surface 421 (as shown in FIG. 10), so that the artificial skin unit 714 has the shapes of the depressed portion 711, the gentle slope portion 712 and the convex portion 713. After the artificial leather unit 714 is cut out, the artificial leather waste 715 is then transported to the recycling mechanism 6.

Please refer to FIG. 14 . In this embodiment, the recovery mechanism 6 has a pulling unit 61 , a first recovery transmission roller 62 , a second recovery transmission roller 63 , a recovery sensing roller 64 , a sensor 65 , a receiving roller 66 and a winding roller 67 . The supporting unit 61, the first recovery transmission roller 62, the second recovery transmission roller 63, the recovery sensing roller 64, the sensor 65, the receiving roller 66 and the winding roller 67 are all installed on the mounting surface 11, wherein the supporting unit 61 is located on the left side of the artificial skin cutting mechanism 5, the first recovery transmission roller 62 is arranged on the upper right side of the supporting unit 61, and the second recovery transmission roller 63 is arranged on the upper left side of the first recovery transmission roller 62, so that the supporting unit 61, the first recovery transmission roller 62 and the second recovery transmission roller 63 are arranged alternately left and right. A recovery sensing roller 64 is disposed above the second recovery transmission roller 63. The recovery sensing roller 64 has a blocking unit 641. The blocking unit 641 is located at the axial rear end of the recovery sensing roller 64. The blocking unit 641 has a plurality of break portions 642. Each break portion 642 is evenly disposed along the circumference of the recovery sensing roller 64. The sensor 65 is a light blocking sensor used to sense the blocking unit 641. The sensor 65 is located on any side of the blocking unit 641 where it can effectively perform sensing. Next, a receiving roller 66 is disposed on the left side above the recovery sensing roller 64, and a take-up roller 67 is disposed above the receiving roller 66. The take-up roller 67 is mounted on the mounting surface 11 through a swing arm 671. In this embodiment, the two ends of the swing arm 671 respectively have a swing end 672 and a pivot end 673. The take-up roller 67 is pivoted on the swing end 672, and the pivot end 673 is pivoted on the mounting surface 11. The swing arm 671 is horizontally placed, the swing end 672 and the winding roller 67 are located above the receiving roller 66, and the pivot end 673 can be located on the right or left side of the swing end 672.

Please refer to FIG. 15 , in this embodiment, the artificial leather waste material 715 is transported to the recycling mechanism 6 . The artificial leather waste material 715 is sequentially wound around the pulling unit 61 , the first recycling transmission roller 62 , the second recycling transmission roller 63 and the recycling sensing roller 64 , and is rolled up on the winding roller 67 . Since the reeling roller 67 is pivoted at the swing end 672, and the pivot end 673 of the swing arm 671 is pivoted at the mounting surface 11, the swing end 672 can naturally droop downward, so that the reeling roller 67 falls on the receiving roller 66. This design is for the artificial leather waste material 715 to be continuously expanded in the process of the reeling roller 67 reeling in the outer periphery of the reeling roller 67, and at the same time, the swing end 672 can make a corresponding swing amplitude. When the swing end 672 naturally droops downward, the artificial leather waste material 715 reeled on the reeling roller 67 contacts the surface of the receiving roller 66. In this way, when recycling the artificial leather waste 715, the receiving roller 66 rotates, and the friction force on the surface of the receiving roller 66 is sufficient to make the artificial leather waste 715 drive the winding roller 67 to rotate, and then the winding roller 67 can continuously rotate to collect the material. In addition, the pulling and supporting unit 61 is used to pull and support the artificial leather waste 715 at the bottom, so that the artificial leather waste 715 can be folded back at a larger angle and then go around the first recycling transmission roller 62. Such a design can largely prevent the artificial leather waste 715 from bringing the artificial leather unit 714 into the recycling mechanism 6. The first recovery transmission roller 62 and the second recovery transmission roller 63 can rotate between the pulling unit 61 and the recovery sensing roller 64 to pull the artificial leather waste 715 for recovery. When the artificial leather waste 715 passes through the recovery sensing roller 64, the artificial leather waste 715 contacts the surface of the recovery sensing roller 64, so that the recovery sensing roller 64 rotates passively, and the blocking unit 641 located on the recovery sensing roller 64 also rotates together, so that the sensor 65 can continuously sense the passing of the break portion 642 on the blocking unit 641 to ensure that the recovery sensing roller 64 continues to rotate under normal operation. In other words, if the sensor 65 continues to sense that the broken part 642 on the blocking unit 641 stops passing, it means that the recovery sensing roller 64 has lost the power to rotate (it may be that the artificial leather waste 715 falls off or breaks), that is, there is a problem in the operation, and the sensor 65 will send a warning signal to the alarm system (not shown) or directly stop the operation to achieve safety monitoring of the production line.

In addition, in other embodiments, the recovery mechanism 6 only needs one recovery drive roller for transmission, and does not need to provide two rollers, the first recovery drive roller 62 and the second recovery drive roller 63. In this way, the artificial leather waste 715 is sequentially wound around the support unit 61, the recovery drive roller (not shown) and the recovery sensing roller 64, and is rolled up on the winding roller 67.

In addition to the artificial leather waste 715 being transported to the recycling agency 6, the artificial leather unit 714 and the base material layer 72 have completed the basic processing procedures and can be cut and packaged later.

The above-mentioned conveying pulley 22, substrate cutting wheel 31, substrate cutting anvil wheel 32, artificial skin cutting wheel 51, artificial skin cutting anvil wheel 52, first recovery transmission roller 62, second recovery transmission roller 63, receiving roller 66 can all be actively rotated, and their rotation can be through motors or gears, etc. This is the driving method of the roller for transmission purpose. How to transmit has no direct relevance to the technology of this case, so it will not be elaborated. In addition, the recovery sensing roller 64 and the winding roller 67 are passively rotated.

In summary, the artificial skin patch manufacturing machine provided by the present invention has the following advantages when compared with other conventional technologies:

1. The hot pressing method of the present invention is to use the hot pressing mechanism 4 for continuous reciprocating operation. Therefore, when the artificial leather belt 7 passes through the hot pressing mechanism 4 for hot pressing, it is not necessary to stop the conveying, and the stability of the tension of the artificial leather belt 7 is not affected, so that the yield of the finished product is increased. In addition, because the overall movement line of the manufacturing machine is a continuous operation, the manufacturing time is reduced.

2. When the artificial skin unit 714 of the present invention is pasted on the skin, there will be no obvious protruding edges, and it will fit the skin more naturally. Different shapes can be used for different products (such as heel patches, acne patches, etc.).

3. The present invention can monitor whether the recycling sensing roller 64 is rotating, further achieving safety monitoring of the production line. In addition, the rewinding roller 67 used to rewind the artificial leather waste 715 is also passively rotated, which can avoid the strong pulling force from tearing the artificial leather waste 715 and improve the stability of recycling.

The above-mentioned embodiments are only some of the preferred embodiments of the present invention, but they are not used to limit the present invention. Any person familiar with this technical field with common knowledge, after understanding the above-mentioned technical features and embodiments of the present invention, and making equal changes or modifications within the spirit and scope of the present invention, still falls within the scope of the present invention, and the scope of patent protection of the present invention shall be subject to the definition of the claim attached to this specification.
