[0001] The present application relates to the field of non-woven fabric production, and in particular to a non-woven fabric hydroentanglement jacquard processing device. Background Art

[0002] Non-woven fabrics are made of oriented or random fibers. They are called cloth because they have the appearance and certain properties of cloth. Non-woven fabrics have no warp and weft, so they are very convenient to cut and sew. They are also light and easy to shape, so they are very popular among handicraft enthusiasts. Because they are a kind of fabric that does not require spinning and weaving, they are just oriented or randomly arranged textile short fibers or filaments to form a fiber mesh structure, and then reinforced by methods such as hydroentanglement, thermal bonding or chemical methods.

[0003] Spunlace jacquard is an important part of the spunlace processing of non-woven fabrics. The fiber fabric is repeatedly entangled by the spunlace equipment, and then a hollow regular pattern or irregular pattern is formed on the spunlace jacquard net. In the related art, the spunlace jacquard equipment includes a spunlace machine and a jacquard roller, which are respectively located on the opposite sides of the fiber fabric. The water stimulation applies pressure to the fabric through high-pressure water flow, and the side of the fabric facing the jacquard net abuts against the jacquard roller, and at the same time, the fabric itself also forms a texture corresponding to the surface pattern of the jacquard roller.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: under specific product requirements, if the demand for the fullness of the particles of the jacquard texture is high, the working power of the spunlace machine needs to be increased, resulting in an increase in energy and resource consumption. Summary of the invention

[0005] In order to improve the above problems, the present application provides a non-woven fabric hydroentanglement jacquard processing equipment.

[0006] The present application provides a non-woven fabric spunlace jacquard processing equipment adopts the following technical solution:

[0007] A non-woven fabric spunlace jacquard processing equipment comprises a frame, on which a first spunlace machine and a jacquard net are arranged, wherein the first spunlace machine and the jacquard net are respectively located on two opposite sides of a fabric, and further comprises an assisting roller, wherein the assisting roller is rotatably connected to the frame, the rotation plane of the assisting roller is parallel to the moving direction of the fabric, and the circumferential surface of the assisting roller abuts against a side of the fabric away from the jacquard net.

[0008] By adopting the above technical solution, when the non-woven fabric is subjected to hydroentanglement jacquard patterning, the assisting roller applies pressure to the non-woven fabric. At this time, the reaction force applied by the jacquard net on the other side of the non-woven fabric to the surface of the non-woven fabric also increases accordingly, and the fullness of the texture particles formed on the surface of the non-woven fabric is improved, thereby meeting specific product requirements.

[0012] Preferably, the rolling mechanism includes a support cylinder, which is fixedly connected to the frame and located in the jacquard drum. The support cylinder includes a major arc cylinder wall and an isolation cylinder wall that are connected to each other.

The second suction chamber is located between the major arc cylinder wall and the isolation cylinder wall. The first suction chamber and the assisting roller are respectively located on the inner and outer sides of the jacquard drum wall. The first suction chamber and the second suction chamber are respectively connected to independent negative pressure ducts.

[0013] By adopting the above technical solution, a smaller enclosed space is formed in the support tube, that is, the pressure of the negative pressure airflow on the surface of the non-woven fabric is increased by reducing the size of the space, that is, the negative pressure airflow can also help increase the fullness of the texture particles on the surface of the non-woven fabric. The second suction chamber also has a negative pressure airflow, which can extract the moisture flowing into the second suction chamber from the support tube.

[0014] Preferably, it also includes an entanglement roller, a second water entanglement machine and a third water entanglement machine, there are two entanglement rollers, the circumferential surfaces of the two entanglement rollers are respectively in contact with the opposite surfaces of the fabric, the water entanglement nozzle of the second water entanglement machine is directed toward the side of the fabric away from one of the entanglement rollers, and the water entanglement nozzle of the third water entanglement machine is directed toward the side of the fabric away from the other entanglement roller.

[0020] By adopting the above technical solution, the limit screw barrel is installed on the control rod and passes through the positioning hole, so that the control rod cannot slide along the guide arc groove, that is, the movable part cannot rotate. When the limit screw barrel is removed from the control rod, its limiting effect on the control rod no longer exists, and the movable part can continue to rotate.

[0021] Preferably, the length of the threaded section on the control rod is smaller than the thickness of the end plate, and the control assembly also includes an adjusting tension spring, one end of which is rotatably connected to the limit screw barrel, and the other end is fixedly connected to the movable part, and the outer diameter of the adjusting tension spring is smaller than the groove width of the guide arc groove.

[0022] By adopting the above technical solution, when the threaded connection between the control rod and the limit screw barrel is released, the limit screw barrel can still be partially present in the positioning hole, limiting the rotation of the movable part. The operator needs to pull the limit screw barrel outward again to make the limit screw barrel completely leave the positioning hole and the movable part can rotate, thereby improving the state stability of the movable part when disassembling the limit screw barrel, thereby improving the safety during operation.

[0023] Preferably, the movable portion is fixedly connected to an abutment frame on the side facing the first suction chamber, the abutment frame includes an arc-shaped rod, the arc-shaped rod is rotatably connected to a plurality of abutment rollers on the side facing the jacquard drum, the rotation plane of the abutment roller and the plane where the trajectory of the arc-shaped rod is located are parallel to the rotation plane of the jacquard drum, an embedded annular groove is coaxially opened on the inner wall of the jacquard drum, the embedded annular groove is for the arc-shaped rod to be embedded, and the wheel surface of the abutment roller abuts against the groove bottom of the embedded annular groove.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Through the setting of the assisting roller, when the non-woven fabric is hydroentangled with jacquard, the assisting roller applies pressure to the non-woven fabric, and the reaction force exerted by the jacquard net on the other side of the non-woven fabric on the surface of the non-woven fabric is also increased, so that the fullness of the texture particles formed on the surface of the non-woven fabric is improved to meet specific product requirements;

[0027] 2. By setting the isolation cylinder wall in the support cylinder, a first suction chamber with a smaller space is formed in the support cylinder, that is, the pressure of the negative pressure airflow on the surface of the non-woven fabric is increased by reducing the size of the space, that is, the negative pressure airflow can also help improve the fullness of the texture particles on the surface of the non-woven fabric;

Both spunlace machines are drum-type, and the two entanglement rollers 23 are arranged in parallel up and down. Both are rotatably connected to the frame 1 and the rotation axis is parallel. The fabric 6 sent out from the feeding platform is S-shaped and passes around the two entanglement rollers 23 in turn. The pre-wet spunlace nozzle 141 is located directly below the lower entanglement roller 23; the spunlace nozzle of the second spunlace machine 21 is directed toward the side of the fabric 6 on the lower entanglement roller 23 away from the entanglement roller 23, and the spunlace nozzle of the third spunlace machine 22 is directed toward the side of the fabric 6 on the higher entanglement roller 23 away from the entanglement roller 23. The second spunlace machine 21 and the third spunlace machine 22 are both provided with two spunlace nozzles.

[0039] like Figure 1 , 2As shown in Figure 3, the frame 1 is also provided with a first water spunlacing machine 13 and a jacquard net 12. The first water spunlacing machine 13 is also a rotary drum type. The rolling mechanism 4 includes a supporting cylinder 41 and a jacquard roller 43. The supporting cylinder 41 is fixedly connected to the frame 1. The rotation axis of the supporting cylinder 41 is horizontal. The jacquard roller 43 is coaxially sleeved outside the supporting cylinder 41, and the two rotate coaxially relative to each other. The jacquard drum 43 is provided with a plurality of water holes 431 penetrating through the wall thickness thereof. The jacquard net 12 is cylindrical and coaxially sleeved on the jacquard drum 43. When the jacquard is in operation, the jacquard net 12 and the jacquard drum 43 are relatively fixed. The fabric 6 leaving the entanglement station 2 bypasses the jacquard drum 43, and the side of the jacquard net 12 away from the jacquard drum 43 is in direct contact with the fabric 6. The jacquard net 12 is formed with a hollow pattern (not shown in the figure) for embossing the surface of the fabric 6. If the pattern on the fabric 6 needs to be replaced, the jacquard net 12 can be replaced. The water jet of the first water jet machine 13 faces the surface of the fabric 6 away from the jacquard net 12.

[0040] like Figure 1 , 4As shown in Figures 5 and 6, in this embodiment, the first spunlacing machine 13 is provided with three spunlacing nozzles. A booster roller 11 is rotatably provided on the frame 1 and located between the last two adjacent spunlacing nozzles of the first spunlacing machine 13. The rotation axis of the booster roller 11 is parallel to the rotation axis of the jacquard roller 43. The roller surface of the booster roller 11 is made of rubber and its circumference is in rolling contact with the side of the fabric 6 away from the jacquard net 12. The structure of the support cylinder 41 includes a major arc cylinder wall 411, an isolation cylinder wall 412 and an end plate 413. The length direction of the major arc cylinder wall 411 and the isolation cylinder wall 412 is the length direction of the support cylinder 41. There are two end plates 413 and they are respectively located at opposite ends of the support cylinder 41. The space formed between the isolation cylinder wall 412 and the major arc cylinder wall 411 is the second suction chamber 415, and the space formed on the side of the isolation cylinder wall 412 away from the second suction chamber 415 and in the jacquard roller 43 is the first suction chamber 414. The two end plates 413 block the ends of the first suction chamber 414 and the second suction chamber 415. The isolation end plate 413, the first suction chamber 414, the assisting roller 11 and the spunlacing nozzles of the first spunlacing machine 13 are all located on the same side of the center of the support cylinder 41, and the assisting roller 11 and the two spunlacing nozzles adjacent to the assisting roller 11 are located on opposite sides of the cylinder wall of the jacquard cylinder 43 with the first suction chamber 414. Two through holes are provided on one of the end plates 413, one of which is located at the end of the first suction chamber 414, and the other is located at the end of the second suction chamber 415. Negative pressure air ducts 46 are fixedly connected to the two through holes on the end plate 413, and the two negative pressure air ducts 46 are independently connected to different exhaust fans (not shown in the figure), that is, the exhaust fans can exhaust the internal spaces of the first suction chamber 414 and the second suction chamber 415 through the negative pressure air ducts 46, and the working power of the two exhaust fans is adjusted, so that a strong negative pressure airflow is formed in the first suction chamber 414, and the negative pressure airflow acts on the fabric 6 through the water holes 431 and the gaps on the jacquard net 12 in turn, thereby increasing the force for forming texture convexities on the surface of the fabric 6. A weak negative pressure airflow is formed in the second suction chamber 415, and a small amount of water entering the second suction chamber 415 can slowly leave the inner cavity of the jacquard cylinder 43 driven by the airflow.

[0041] like Figure 3 , 4As shown in Figure 5, the position of the isolation tube wall 412 is higher than the center of the support tube 41, and the isolation tube wall 412 includes a fixed portion 44 and a movable portion 45. The end plate 413 is fixedly connected to the fixed portion 44 and the primary arc tube wall 411, and the plate surface of the end plate 413 is perpendicular to the axis of the support tube 41; the movable portion 45 is rotatably connected to the fixed portion 44 and the rotation axis is parallel to the length direction of the support tube 41, the rotation axis of the movable portion 45 and the fixed portion 44 and the first suction chamber 414 are located on the same side of the axis of the primary arc tube wall 411, and the end of the movable portion 45 away from the fixed portion 44 abuts against the upper edge of the primary arc tube wall 411. After the processing is completed, the movable part 45 is turned over, the jacquard roller 43 is removed, and the first suction chamber 414 and the second suction chamber 415 are connected to each other, and the side of the isolation cylinder wall 412 facing the first suction chamber 414 can be sprayed with water for cleaning, and the jacquard roller 43 can be cleaned by spraying water from one side of the first suction chamber 414. The water flow finally flows into the second suction chamber 415, and is finally sucked out by the negative pressure duct connected to the second suction chamber 415.

[0042] like Figure 4 , 5 As shown in Figure 6, the rolling mechanism 4 includes a control assembly 5 for controlling the rotation of the movable part 45. The control assembly 5 includes a control rod 51 and a stopper 52. The control rod 51 is fixedly connected to the edge of the movable part 45, and the length direction of the control rod 51 is parallel to the rotation axis of the movable part 45. A guide arc groove 4131 is provided on the end plate 413. The trajectory of the guide arc groove 4131 is concentric with the rotation trajectory of the movable part 45. The guide arc groove 4131 is for the control rod 51 to pass through. The stopper 52 is detachably connected to the control rod 51, and controls whether the control rod 51 stops at a specified position on the guide arc groove 4131. In this embodiment, the stopper 52 is a stopper screw barrel, and a threaded structure is formed on the control rod 51. The stopper screw barrel is coaxially threadedly connected to the control rod 51. A positioning hole 4132 is provided on the end plate 413 and at the end of the guide arc groove 4131. The positioning hole 4132 is connected to the guide arc groove 4131. The radial dimension of the positioning hole 4132 is consistent with the outer diameter of the limiting screw barrel and is larger than the guide arc groove 4131. That is, when the limiting screw barrel is threadedly connected to the control rod 51 and the limiting screw barrel is inserted into the positioning hole 4132, the limiting screw barrel, the control rod 51 and the movable part 45 cannot move along the guide arc groove 4131.

[0043] like Figure 4 and 6As shown, the threaded section on the control rod 51 is entirely located within the thickness range of the end plate 413, and the length of the threaded section is less than the thickness of the end plate 413, that is, when the threaded connection between the control rod 51 and the limiting screw barrel is released, the limiting screw barrel can still be partially present in the positioning hole 4132 to limit the rotation of the movable part 45. The control assembly 5 also includes an adjustment spring 53, which is coaxially sleeved outside the control rod 51, and one end of the adjustment spring 53 is rotationally connected to the limiting screw barrel, and the other end is fixedly connected to the movable part 45. The adjustment spring 53 applies a pulling force toward the movable part 45 to the limiting screw barrel, and the outer diameter of the adjustment spring 53 is less than the groove width of the guide arc groove 4131. After the limiting screw barrel is rotated to disengage from the thread on the control rod 51, the operator needs to pull the limiting screw barrel outward again to make the limiting screw barrel completely leave the positioning hole 4132, and the movable part 45 can rotate.

[0044] like Figure 4 and 5 As shown, the movable part 45 is fixedly connected to the side facing the first suction chamber 414 with an abutment frame 42, and the abutment frame 42 includes a plurality of arc-shaped rods 421, which are arranged in an array along the length direction of the movable part 45, and the arc-shaped rods 421 are rotatably connected to the side facing the jacquard cylinder 43 with a plurality of abutment rollers 422, and the rotation plane of the abutment rollers 422 and the plane where the trajectory of the arc-shaped rods 421 is located are parallel to the rotation plane of the jacquard cylinder 43, and the center of the contour trajectory of each arc-shaped rod 421 coincides with the rotation axis of the jacquard cylinder 43. The inner wall of the jacquard cylinder 43 is coaxially provided with an embedded annular groove 432, and the number of the embedded annular groove 432 is consistent with the number of the arc-shaped rods 421, and the embedded annular groove 432 is for the arc-shaped rods 421 to be embedded, and the wheel surface of the abutment roller 422 abuts against the groove bottom of the embedded annular groove 432. During the jacquard processing, the assisting roller 11 continuously applies thrust to the fabric 6, the jacquard net 12 and the jacquard cylinder 43, and the arc rod 421 is located on the side of the jacquard cylinder 43 away from the assisting roller 11 and abuts against the inner wall of the jacquard cylinder 43. Since the arc rod 421 is embedded in the embedded annular groove 432, the force balance of the jacquard cylinder 43 is improved, and the position stability of the jacquard cylinder 43 relative to the support cylinder 41 is also improved. After the processing is completed, the movable part 45 is operated to rotate by the control component 5, and the movable part 45 drives the abutment frame 42 to rotate, so that the arc rod 421 leaves the embedded annular groove 432, and the limit of the abutment frame 42 on the jacquard cylinder 43 can be released, providing an operating space for moving the jacquard cylinder 43 out of the support cylinder 41.

[0045] like Figure 1 As shown, the fabric 6 is wound off the jacquard roller 43 and moves to the drying mechanism 3. The drying mechanism 3 includes a dehydration platform 31 and a water suction box 32 located in the dehydration platform 31. The dehydration platform 31 is located below the fabric 6. The water suction box 32 can generate negative pressure airflow, which applies negative pressure to the continuously moving fabric 6 to dehydrate it as quickly as possible.

[0046] The implementation principle of a non-woven fabric spunlace jacquard processing device in the embodiment of the present application is:

[0047] When the hydroentangled fabric 6 is jacquard processed, while the first hydroentanglement machine 13 hydroentangles and pressurizes the fabric 6, the auxiliary roller 11 increases the pressure on the fabric 6 by applying abutting force. At the same time, the negative pressure in the first suction chamber 414 can also produce a certain mechanical effect on the surface of the fabric 6. The three forces are applied simultaneously to make the texture particles on the fabric 6 fuller.

[0048] 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.
