Abstract

The present invention proposes a device and method for laminating an antibacterial layer on the surface of an antibacterial non-woven fabric, comprising a base frame, a conveying device, a rotating drum, a plurality of laminating components and a matching frame, wherein the laminating components include a first connecting frame, a second connecting frame, a cloth pressing member and a spring. When the cloth pressing member is connected to the matching frame and moves an internode distance before disengaging from the matching frame, another cloth pressing member automatically connects to the matching frame and presses on the top of the antibacterial cloth layer to continue conveying the non-woven fabric body and the antibacterial cloth layer. Since each cloth pressing member laminates and conveys the antibacterial cloth layer while being connected to the matching frame, step-by-step conveying of the antibacterial cloth layer can be achieved, thereby increasing the conveying stability of the antibacterial cloth layer. Moreover, each time the antibacterial cloth layer is laminarized by the cloth pressing member, the covering position of the antibacterial cloth layer can be corrected, thereby preventing the antibacterial cloth layer from being misaligned relative to the non-woven fabric body during the conveying process, thereby increasing the stability of the antibacterial cloth layer covering the non-woven fabric body and facilitating use.

Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric manufacturing, and in particular to a device and method for laminating an antibacterial layer on the surface of an antibacterial non-woven fabric. Background Art

[0002] Antibacterial non-woven fabric is a type of non-woven fabric made by needle punching process. It has the characteristics of light weight, softness and breathability. At the same time, because its surface is covered with an antibacterial layer, it has good antibacterial properties during use and has a better antibacterial effect against common bacteria that people often come into contact with.

[0003] The invention with publication number CN114250631A proposes a high-toughness antibacterial non-woven fabric and its preparation method. The preparation method of the antibacterial non-woven fabric is through setting an antibacterial coating on the surface of the above-mentioned non-woven fabric base layer, and a waterproof coating, which is coated on the outside of the above-mentioned antibacterial coating. The non-woven fabric base layer is formed by melt-blown textile processing of polyester fiber and high-grade propylene fiber, and the antibacterial solution and waterproof coating are coated on the outside of the non-woven fabric base layer, thereby enhancing the antibacterial and waterproof properties of the non-woven fabric. Specifically, when producing antibacterial non-woven fabrics, it is necessary to adjust the antibacterial cloth layer coated with the antibacterial coating and the non-woven fabric body for surface covering connection. Two transmission mechanisms are set to transmit the antibacterial cloth layer coated with the antibacterial coating and the non-woven fabric body respectively, and the antibacterial cloth layer is transported and covered to the surface of the non-woven fabric body to connect the antibacterial cloth layer and the non-woven fabric body. However, since the transportation method of the antibacterial cloth layer and the non-woven fabric body is long-distance transportation, when the antibacterial cloth layer is transported and covered to the surface of the non-woven fabric body, the long-term transportation will cause transportation deviation, and a part of the non-woven fabric cannot be covered by the antibacterial cloth layer, which leads to waste of resources. Therefore, this solution specially proposes an antibacterial non-woven fabric surface antibacterial layer covering device and method to solve the above problem. Summary of the Invention

Since each cloth pressing piece presses and transports the antibacterial cloth layer during the connection with the matching frame, step-by-step transportation of the antibacterial cloth layer can be achieved, thereby increasing the transportation stability of the antibacterial cloth layer. Each time the antibacterial cloth layer is pressed by the cloth pressing piece, the covering position of the antibacterial cloth layer can be corrected to prevent the antibacterial cloth layer from being displaced relative to the non-woven fabric body during transportation, thereby increasing the stability of the antibacterial cloth layer covering the non-woven fabric body and facilitating use.

When the cloth pressing member 53 rotates to press on the antibacterial cloth layer 32, it can move synchronously with the antibacterial cloth layer 32 by an internode distance; a spring 54 is provided between the first connecting frame 51 and the second connecting frame 52 for resetting the rotation angle of the second connecting frame 52 relative to the first connecting frame 51. Plates are provided on both the first connecting frame 51 and the second connecting frame 52. , the spring 54 is fixedly connected to the plate; the matching frame 6 is movably arranged relative to the base frame 1 and is selectively connected to the cloth pressing member 53. When the cloth pressing member 53 is connected to the matching frame 6, the cloth pressing member 53 can only move up and down relative to the matching frame 6. The moving direction of the matching frame 6 is parallel to the conveying direction of the conveyor belt 21, and the moving speed of the matching frame 6 is consistent with the transmission speed of the conveyor belt 21. When the cloth pressing member 53 rotates to press on the antibacterial cloth layer 32, the cloth pressing member 53 is synchronously connected to the matching frame 6 and moves synchronously with the matching frame 6.

[0047] Figure 1 The X direction is the conveying direction, the Y direction is the width direction of the antibacterial cloth layer 32, and the Z direction is the height direction.

[0048] In a specific implementation, when the non-woven fabric body 31 and the antibacterial cloth layer 32 are both conveyed to the conveyor belt 21 on their respective conveying mechanisms, the conveyor belt 21 conveys the non-woven fabric body 31 and the antibacterial cloth layer 32, and at the same time, the rotating drum 4 rotates according to the conveying speed of the conveyor belt 21, and drives the cloth pressing member 53 to selectively press on the top of the antibacterial cloth layer 32. When the cloth pressing piece 53 is pressed on the top of the antibacterial cloth layer 32, it is automatically connected to the matching frame 6 and moves synchronously with the matching frame 6 along the conveying direction of the conveyor belt 21. During this period, the second connecting frame 52 rotates relative to the first connecting frame 51, and the spring 54 is compressed. The non-woven fabric body 31 and the antibacterial cloth layer 32 are transported under the dual action of the cloth pressing piece 53 and the conveyor belt 21. When the cloth pressing piece 53 is connected to the matching frame 6 and moves an internode distance and then separates from the matching frame 6, at this time, another cloth pressing piece 53 is automatically connected to the matching frame 6 and pressed on the top of the antibacterial cloth layer 32 to continue to convey the non-woven fabric body 31 and the antibacterial cloth layer 32. Since each cloth pressing member 53 presses and conveys the antibacterial cloth layer 32 during the connection with the matching frame 6, by arranging each cloth pressing member 53 to convey the antibacterial cloth layer 32 by moving an internode distance after connecting to the matching frame 6, the antibacterial cloth layer 32 can be conveyed in a step-by-step manner, thereby increasing the conveying stability of the antibacterial cloth layer 32. Moreover, each time the antibacterial cloth layer 32 is pressed by the cloth pressing member 53, the covering position of the antibacterial cloth layer 32 can be corrected, thereby preventing the antibacterial cloth layer 32 from being misaligned relative to the non-woven fabric body 31 during the conveying process, thereby increasing the stability of the antibacterial cloth layer 32 covering the non-woven fabric body 31 and facilitating use.

[0049] As a preferred embodiment, multiple matching frames 6 are respectively located on opposite sides of the conveying equipment 2 and are fixedly connected to the conveyor belt 21. A sliding hole 61 is opened on the matching frame 6, and the sliding hole 61 is connected to the top of the matching frame 6. The cloth pressing piece 53 includes two protrusions 531, and the two protrusions 531 are respectively located on opposite sides of the cloth pressing piece 53 and are selectively inserted into the inside of the sliding hole 61.

[0050] In a specific implementation, the conveyor belt 21 drives the matching frame 6 to move so that the conveying speed of the matching frame 6 is consistent with that of the conveyor belt 21. The protrusion 531 is a square block. When the cloth pressing member 53 rotates to the top of the antibacterial cloth layer 32, it can automatically rotate and be inserted into the inside of the sliding hole 61. After insertion, it can only slide up and down along the sliding hole 61, thereby pressing the antibacterial cloth layer 32 and conveying the antibacterial cloth layer 32 in a step-by-step manner.

[0051] As a preferred embodiment, the matching frame 6 includes a high limit frame 62 and a low limit frame 63. The high limit frame 62 and the low limit frame 63 are both located on the side of the matching frame 6 close to the rotating drum 4. The sliding hole 61 is formed between the high limit frame 62 and the low limit frame 63. The arrangement direction of the low limit frame 63 and the high limit frame 62 is parallel to the rotation direction of the rotating drum 4, and the height of the low limit frame 63 is lower than the height of the high limit frame 62.

[0052] With this design, when the cloth pressing piece 53 wants to rotate in the direction closer to the matching frame 6, the cloth pressing piece 53 first rotates to the lower limit frame 63. Since the height of the low limit frame 63 is lower than the high limit frame 62, the protrusion 531 can be better rotated to fit with the side wall of the high limit frame 62. Since the protrusion 531 is a square block, the protrusion 531 can be stabilized when it fits with the high limit frame 62 to prevent the cloth pressing piece 53 from rotating relative to the second connecting frame 52, and the protrusion 531 can be better moved down and inserted into the inside of the sliding hole 61.

[0053] As a preferred embodiment, a friction base pad 7 is further included, wherein the friction base pad 7 is a rubber base pad, which is arranged on the cloth pressing member 53 and selectively attached to the top of the antibacterial cloth layer 32 .

[0054] In a specific implementation, when the cloth pressing member 53 rotates to press on the top of the antibacterial cloth layer 32 , the friction base pad 7 contacts the antibacterial cloth layer 32 .

[0055] As a preferred embodiment, the friction base pad 7 covers the antibacterial cloth layer 32 in the width direction of the antibacterial cloth layer 32 .

[0056] With this design, when the friction base pad 7 is pressed on the top of the antibacterial cloth layer 32, the friction base pad 7 can cover the antibacterial cloth layer 32 in the width direction of the antibacterial cloth layer 32, and can press down the edges and corners of the antibacterial cloth layer 32 in the width direction, so that the antibacterial cloth layer 32 completely covers the non-woven fabric body 31, thereby increasing the stability of the antibacterial cloth layer 32 covering the non-woven fabric body 31.

[0057] As a preferred embodiment, it also includes multiple side connecting members 8, wherein the multiple side connecting members 8 are respectively arranged on opposite sides of the conveying equipment 2 and are selectively connected to the matching frame 6. When the matching frame 6 is connected to the side connecting members 8, the matching frame 6 can only slide along the side connecting members 8 in the conveying direction of the conveyor belt 21.

[0058] In a specific implementation, whenever the matching frame 6 moves along the conveying direction, it can be connected to the side connecting piece 8. At this time, the matching frame 6 can only slide along the side connecting piece 8 in the opposite direction of conveying, and the side connecting piece 8 can support the matching frame 6 during the movement to prevent the matching frame 6 from deflecting, thereby increasing the service life of the matching frame 6 and increasing the connection stability of the matching frame 6 to the cloth pressing piece 53, making it convenient to use.

[0059] As a preferred embodiment, a sliding groove 81 is provided on the side connecting member 8 , and the sliding groove 81 is connected to two opposite sides of the side connecting member 8 , and the plurality of matching frames 6 are selectively slidably connected to the sliding groove 81 .

[0060] In a specific implementation, when the matching frame 6 moves to the side connecting member 8, it is slidably connected to the side connecting member 8 by inserting into the sliding groove 81 and sliding along the sliding groove 81, and the groove wall of the sliding groove 81 has a limiting effect on the matching frame 6, and the matching frame 6 can only slide along the sliding groove 81 in the conveying direction.

[0061] As a preferred embodiment, it also includes a driving component 9, and the base frame 1 includes a lower side frame 11 and an upper side frame 12, wherein there are two lower side frames 11, which are respectively located on opposite sides of the conveying equipment 2, and the lower side frame 11 is fixedly connected to the middle part of the conveying equipment 2 in the height direction through a connecting rod 13; the upper side frame 12 is arranged on the lower side frame 11 and is located on one side of the rotating drum 4; the driving component 9 is a motor, which is arranged on the upper side frame 12 and is used to drive the rotating drum 4 to rotate.

[0062] As a preferred embodiment, it also includes a flip plate 20, wherein the flip plate 20 is fixedly connected to the upper side frame 12 and is located on the rotation path of the cloth pressing member 53 above. Its top wall is arc-shaped, and the arc center of the top wall of the flip plate 20 coincides with the rotation center axis of the rotating drum 4, and selectively conflicts with the cloth pressing member 53.

[0063] With this design, when the cloth pressing piece 53 rotates to the top, the cloth pressing piece 53 and the curved top wall of the flip plate 20 are at the bottom, and the connection between the curved top wall and its side wall is a curved surface. Under the action of the curved surface, the cloth pressing piece 53 can be flipped and guided onto the curved top wall, and rotated along the curved top wall. During the rotation process, the cloth pressing piece 53 continues to flip relative to the second connecting frame 52, thereby flipping the cloth pressing piece 53 from one side of the second connecting frame 52 to the other side until it is separated from the curved top wall. Under the action of the curved top wall, the cloth pressing piece 53 can be flipped relatively smoothly from the top, so that the cloth pressing piece 53 can be smoothly moved to the antibacterial cloth layer 32 and connected to the matching frame 6.

[0064] The present invention also discloses a method for laminating an antibacterial layer on the surface of an antibacterial non-woven fabric, comprising the device for laminating an antibacterial layer on the surface of an antibacterial non-woven fabric as described in any one of the above items, comprising the following steps:

[0065] Step 1: The rotation speed of the drum 4 is set to match the conveying speed of the conveyor belt 21. The non-woven fabric body 31 and the antibacterial fabric layer 32 are conveyed to one end of the conveyor belt 21 and then transferred to the other end of the conveyor belt 21 on their respective conveying mechanisms.

[0066] Step 2: While the conveyor belt 21 supports and conveys the non-woven fabric body 31 and the antibacterial fabric layer 32, the rotating drum 4 is adjusted to rotate synchronously. This causes the rotating drum 4 to drive the multiple cloth pressing members 53 to rotate synchronously. When the cloth pressing members 53 press on top of the antibacterial fabric layer 32, the protrusions 531 engage the sliding holes 61, automatically connecting with the matching frame 6. The second connecting frame 52 rotates relative to the first connecting frame 51, compressing the spring 54.

[0067] Step 3: The cloth pressing member 53 is connected to the matching frame 6 and moves one internode distance and then separates from the matching frame 6. When one cloth pressing member 53 moves one internode distance, the other cloth pressing member 53 is automatically connected to the matching frame 6 and pressed on the top of the antibacterial cloth layer 32.

[0068] Step 4: Repeat steps 2 and 3 to press the antibacterial cloth layer 32 onto the surface of the non-woven fabric body 31 and transport it.

[0069] The working principle of the present invention is described below:

[0070] The nonwoven fabric body 31 and the antibacterial fabric layer 32 are both conveyed to the conveyor belt 21 on their respective conveying mechanisms. The rotating drum 4 rotates according to the conveying speed of the conveyor belt 21 and drives the cloth pressing member 53 to selectively press on the top of the antibacterial fabric layer 32. When the cloth pressing piece 53 is pressed on the top of the antibacterial cloth layer 32, it is automatically inserted into the sliding hole 61 on the matching frame 6 to connect with the matching frame 6. At this time, the cloth pressing piece 53 can only move up and down relative to the matching frame 6, and move synchronously with the matching frame 6 along the conveying direction of the conveyor belt 21. At this time, the matching frame 6 slides along the side connecting piece 8, and the second connecting frame 52 rotates relative to the first connecting frame 51. The spring 54 is compressed, and the friction base pad 7 covers the antibacterial cloth layer 32 in the width direction of the antibacterial cloth layer 32. The non-woven fabric body 31 and the antibacterial cloth layer 32 are transported under the dual action of the cloth pressing piece 53 and the conveyor belt 21. When the cloth pressing piece 53 is connected to the matching frame 6 and moves an internode distance and then disengages from the matching frame 6, at this time, another cloth pressing piece 53 is automatically connected to the matching frame 6 and pressed on the top of the antibacterial cloth layer 32 to continue conveying the non-woven fabric body 31 and the antibacterial cloth layer 32. When the cloth pressing member 53 rotates upward, it comes into contact with the turning plate 20 and is automatically turned over relative to the second connecting frame 52 under the action of the turning plate 20 .

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
