Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to an automatic detection device for non-woven fabrics. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, etc., are made of directional or random fibers. They are called cloth because they have the appearance and certain properties of cloth. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, and recyclable. The produced non-woven fabrics need to be tested before rolling to confirm whether they are qualified.

[0003] The existing Chinese patent with announcement number CN214668679U provides an intelligent detection device for non-woven fabrics, which is provided with a detection chamber, a drying chamber and a preheating chamber and a first guide roller and a second guide roller for guiding. The non-woven fabric is sequentially wrapped around the guide rollers in the preheating chamber and the drying chamber and then enters the detection chamber. In this way, the non-woven fabric is preheated and dried in the preheating chamber and the drying chamber, which is beneficial to subsequent detection, marking and preservation.

[0004] However, the above patent still has some defects: the guide rollers are arranged inside the preheating chamber, the drying chamber and the detection chamber. Before the detection, the head end of the non-woven fabric needs to be pulled from the unwinding roller on one side of the frame and successively wrapped around the guide rollers of the preheating chamber, the drying chamber and the detection chamber and then fixed on the winding roller. It is inconvenient to thread the non-woven fabric, and then it is inconvenient to replace two adjacent non-woven fabrics, which reduces the replacement rate of the non-woven fabric and reduces the overall detection efficiency of the non-woven fabric.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Please refer to Figure 1-Figure 3 The present embodiment provides an automatic non-woven fabric detection device, comprising a frame 1, a detection chamber 11, a drying chamber 12 and a preheating chamber 13 arranged on the frame 1 in sequence, and a guide roller 2 is rotatably connected to the drying chamber 12, the preheating chamber 13 and the detection chamber 11; two rotating shafts 3 are symmetrically installed at the bottom of the frame 1, sprocket wheels 4 are installed at both ends of the rotating shaft 3 and on both sides of the guide roller 2, and the sprocket wheels 4 on the rotating shaft 3 are fixedly connected to the rotating shaft 3, while the sprocket wheels 4 on both sides of the guide roller 2 are rotatably connected to the guide roller 2; the sprocket wheels 4 on the same side of the frame 1 are jointly sleeved with a chain 5, and the chain 5 should pass through all the sprocket wheels 4 one by one, and a clamp 6 for clamping non-woven fabric is installed on the chain 5, and a driving mechanism 7 for driving the rotating shaft 3 to rotate is also installed at the bottom of the frame 1.

[0022] The following is a further introduction in combination with specific usage scenarios. When testing non-woven fabrics, first control the chain 5 to operate so that the clamp 6 moves to the entrance of the preheating chamber 13, and then clamp the two corners of the head end of the non-woven fabric on the unwinding roller with two clamps 6 respectively; then start the driving mechanism 7 to control the rotation of the shaft 3 and then control the rotation of the sprocket 4, thereby driving the chain 5 to operate. As the chain 5 operates, the two clamps 6 will pull the head end of the non-woven fabric through the guide rollers 2 of the preheating chamber 13 and the drying chamber 12 in turn, and preheat and dry in the preheating chamber 13 and the drying chamber 12 in turn, and then pull the dried non-woven fabric to run to the detection chamber 11 and pass through the outlet of the detection chamber 11. At this time, the non-woven fabric is passed from the entrance of the detection device to the outlet of the detection device, and the threading operation of the non-woven fabric is simple. Finally, release the two clamps 6, and fix the head end of the non-woven fabric on the winding roller, and provide winding force for the subsequent fabric detection process through the winding roller.

[0023] It should be noted here that a unwinding roller can be set at the entrance of the preheating chamber 13 of the frame 1 for unwinding the non-woven fabric, and a winding roller can be set at the exit of the detection chamber 11 of the frame 1 to wind up the non-woven fabric that has been detected; in addition, the sprockets 4 on both sides of the guide roller 2 are rotatably connected to the guide roller 2, and the sprockets 4 on the rotating shaft 3 are fixedly connected to the rotating shaft 3. This is because, when the cloth is guided, the rotation of the rotating shaft 3 is controlled by the driving structure, which then drives the sprockets 4 on the rotating shaft 3 to rotate synchronously, thereby providing power for the operation of the chain 5. After the non-woven fabric is guided from one side of the detection device to the other side, the winding roller increases the force for winding the non-woven fabric in the subsequent detection process. At this time, the chain 5 does not need to operate, so the driving structure is not in operation, and the guide roller 2 rotates under the friction force with the non-woven fabric.

[0024] On the whole, a rotating shaft 3 is arranged at the bottom of the frame 1, and sprockets 4 are installed at both ends of the rotating shaft 3 and the guide rollers 2. A chain 5 is sleeved on the sprocket 4 on the same side of the frame 1, and clamps 6 are arranged on the two chains 5. The two clamps 6 are used to clamp the two corners of the head end of the non-woven fabric, and the rotation of the rotating shaft 3 is controlled by the driving device to control the operation of the chain 5, so as to pull the non-woven fabric through the preheating chamber 13, the drying chamber 12 and the detection chamber 11 in turn, which can facilitate the threading of the non-woven fabric, improve the replacement rate of the non-woven fabric, and thus improve the overall detection efficiency.

[0025] Reference Figure 2 and Figure 3 As a specific implementation of the embodiment of the present application, the clamp 6 includes a mounting plate 61 fixed to the side of one of the outer link plates of the chain 5, a lower clamping plate 62 is fixed to the side of the mounting plate 61, an upper clamping plate 63 is slidably connected to the side of the mounting plate 61, and a first locking bolt 64 is rotatably connected to the upper clamping plate 63, and the first locking bolt 64 is threadedly connected to the lower clamping plate 62.

[0026] In combination with specific usage scenarios, when threading the non-woven fabric, the two corners of the head end of the non-woven fabric are placed on the lower clamping plates 62 of the two clamps 6 respectively, and then the two first locking bolts 64 are screwed respectively, so that the lower clamping plate 62 gradually approaches the upper clamping plate 63 and then clamps the two corners of the non-woven fabric. The operation is simple and convenient.

[0027] Reference Figure 3 As a specific implementation of the embodiment of the present application, the clamping surfaces of the upper clamping plate 63 and the lower clamping plate 62 are stepped, and the clamping surfaces of the upper clamping plate and the lower clamping plate are opposite surfaces of the two.

[0028] In combination with specific usage scenarios, the clamping surfaces of the upper clamping plate 63 and the lower clamping plate 62 are designed to be stepped, which not only increases the clamping area of ​​the leading corners of the non-woven fabric, but also makes the clamping of the non-woven fabric more stable when pulling the non-woven fabric, thereby ensuring the stability and reliability of the non-woven fabric threading.

[0029] As a specific implementation of the embodiment of the present application, anti-slip rubber pads are fixedly connected to the clamping surfaces of the upper clamping plate 63 and the lower clamping plate 62.

[0030] In combination with specific usage scenarios, by fixing anti-slip rubber pads on the clamping surfaces of the upper clamp 63 and the lower clamp 62, not only can the friction coefficient between the clamp 6 and the non-woven fabric be increased, the clamping effect on the non-woven fabric can be further improved, thereby ensuring the stability of the non-woven fabric threading; in addition, the degree of extrusion of the non-woven fabric surface by the clamp 6 can be reduced, thereby ensuring the surface quality of the clamped part of the non-woven fabric to a certain extent.

[0031] Reference Figure 2 and Figure 3 As a specific implementation of the embodiment of the present application, a connecting plate 8 is installed between the two clamps 6, specifically, between the two lower clamps 62.

[0032] In combination with specific usage scenarios, by installing a connecting plate 8 between the two clamps 6, the connection strength between the two clamps 6 can be increased, ensuring that the two clamps 6 are not easily tilted when moving with the chain 5, thereby improving the stability of the non-woven fabric threading work.

[0033] Reference Figure 2 and Figure 3 As a specific implementation of the embodiment of the present application, an auxiliary clamping member 9 is installed in the middle of the connecting plate 8, and the auxiliary clamping member 9 includes an auxiliary clamping plate 91 slidingly connected to the connecting plate 8, and a second locking bolt 92 is rotatably connected to the auxiliary clamping plate 91, and the second locking bolt 92 is threadedly connected to the connecting plate 8.

[0034] In combination with specific usage scenarios, when threading the non-woven fabric, two clamps 6 are used to clamp the two corners of the non-woven fabric, and then the second locking bolt 92 is screwed, and the auxiliary clamping plate 91 and the connecting plate 8 are used to auxiliary clamp the middle position of the head end of the non-woven fabric, thereby ensuring the stability of the clamping of the non-woven fabric, and further ensuring the stability of the threading of the non-woven fabric.

[0035] Reference Figure 2 As a specific implementation of the embodiment of the present application, the driving mechanism 7 includes a driving motor 71, and pulleys 72 are fixedly connected to the shaft ends of the driving motor 71 and the rotating shaft 3, and a belt 73 is commonly sleeved on the outer sides of the two pulleys 72.

[0036] In combination with the specific usage scenario, by starting the driving motor 71, the rotating shaft 3 is driven to rotate under the transmission of the pulley 72 and the belt 73, thereby driving the chain 5 to operate, and further driving the clamp 6 to move with the chain 5, thereby pulling the non-woven fabric from the fabric inlet of the detection device to the fabric outlet of the detection device.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
