Description

Technical Field

[0001] This application relates to the field of nonwoven fabric processing, and in particular to a continuous hot-pressing and consolidation device for composite nonwoven fabrics. Background Technology

[0002] Composite nonwoven fabric is a nonwoven material made by combining two or more different fiber materials. With the advancement of materials science, composite nonwoven fabric is increasingly widely used in medical, hygiene, filtration materials and industrial fields because it combines the properties of multiple fibers. Nonwoven fabric hot pressing uses the pressure and temperature of hot press rollers to solidify different fiber materials into a material with a certain thickness and mass.

[0003] However, in the process of implementing the relevant technical solutions, at least the following technical problems were found: During the continuous hot pressing and consolidation process of composite nonwoven fabric, the nonwoven fabric is generally fed to the hot pressing roller using a conveying roller. During the conveying process, the nonwoven fabric is prone to displacement, causing the nonwoven fabric that has not been hot pressed to move on the hot pressing roller. In addition, if there are impurities such as dust on the surface of the nonwoven fabric during continuous hot pressing, it will also affect the hot pressing, thereby reducing the hot pressing quality. Utility Model Content

[0004] This application provides a continuous hot-pressing and consolidation device for composite nonwoven fabrics, which solves the problem of easy deviation of nonwoven fabrics during conveying in the prior art and achieves the effect of limiting the two sides of the nonwoven fabric.

Detailed Implementation

[0017] This application discloses a continuous hot-pressing and consolidation device for composite nonwoven fabric. The reciprocating screw 42 drives the threaded slider 44 to reciprocate, so that the slider 44 drives the two bottom limiting plates 55 to reciprocate on both sides of the nonwoven fabric, thereby limiting the nonwoven fabric and preventing it from shifting during hot pressing.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a continuous hot-pressing and consolidation device for composite nonwoven fabrics, including a base 10. A hot press 20 is arranged on the side of the top of the base 10. A reciprocating assembly 40 is arranged in the middle of the base 10. A limit assembly 50 is arranged at the bottom of the reciprocating assembly 40. A cleaning assembly 60 is arranged on the front of the limit assembly 50. The reciprocating assembly 40 includes a connecting seat 41, a reciprocating screw 42, a reduction motor 43, and a slider 44. Two connecting seats 41 are arranged on both sides of the middle of the top of the base 10. The reciprocating screw 42 is rotatably connected between the two connecting seats 41. The reduction motor 43 is fixedly installed on one side of one of the connecting seats 41, and the output shaft of the reduction motor 43 is fixedly connected to the reciprocating screw 42. The slider 44 is sleeved and threadedly connected to the outer side of the threaded part in the middle of the reciprocating screw 42. A tension roller 30 is arranged on the top of the base 10. The tension roller 30 is arranged between the hot press 20 and the reciprocating assembly 42. Between the lead screws 42, the limiting assembly 50 includes a connecting sleeve 51, a fixing plate 52, a threaded rod 53, a knob 54, and limiting plates 55. The two limiting plates 55 are located at the bottom of the reciprocating lead screw 42. The reciprocating assembly 40 is used to drive the two limiting plates 55 to move back and forth. The height of the tension roller 30 is lower than that of the reciprocating lead screw 42, so that the nonwoven fabric can pass through the two limiting plates 55 and be placed at the bottom of the tension roller 30. The output shaft of the reduction motor 43 drives the reciprocating lead screw 42 between the two connecting seats 41 to rotate. The reciprocating lead screw 42 drives the slider 44 threadedly connected to it to move back and forth, thereby driving the two limiting plates 55 to move back and forth. The nonwoven fabric is placed between the two limiting plates 55. The two limiting plates 55 move on both sides of the nonwoven fabric and alternately contact both sides of the nonwoven fabric, so that the two limiting plates 55 can straighten the nonwoven fabric when the nonwoven fabric is deviated, thereby improving the hot pressing quality of the nonwoven fabric.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3Two connecting sleeves 51 are fixedly mounted on both ends of the slider 44, and the two connecting sleeves 51 are sleeved on the outside of the reciprocating screw 42. A fixing plate 52 is fixedly mounted on the outside of the bottom of the connecting sleeves 51. A threaded rod 53 is threadedly connected to the middle of the fixing plate 52, and one end of the threaded rod 53 is fixedly connected to the limiting plate 55. A knob 54 is fixedly mounted on the outer end of the threaded rod 53. The two connecting sleeves 51 are fixed to both ends of the slider 44, so that when the slider 44 reciprocates, it can drive the two connecting sleeves 51 to move accordingly. 1. It does not contact the outside of the reciprocating screw 42 to prevent the reciprocating screw 42 from rotating with it. The screw rod 53 is rotated by the knob 54, so that the limiting plate 55 can move on one side of the fixed plate 52, thereby changing the distance between the two limiting plates 55. When the connecting sleeve 51 moves to the outermost position with the slider 44, one limiting plate 55 just contacts the edge of the nonwoven fabric. This allows the reciprocating movement of the two limiting plates 55 to straighten the offset nonwoven fabric and prevent the nonwoven fabric from shifting, which would affect the hot pressing quality of the nonwoven fabric.

[0021] Please refer to Figure 1 , Figure 2 and Figure 3 The cleaning assembly 60 includes connecting rods 61, fixed seats 62, guide rails 63, movable sleeves 64, and cleaning brushes 65. Two fixed seats 62 are fixedly mounted on both sides of the top of the base 10, and are positioned on the front of the reciprocating screw 42. The guide rail 63 is fixedly mounted between the two fixed seats 62. The movable sleeve 64 is fitted onto and slidably connected to the outside of the guide rail 63. The cleaning brush 65 is fixedly mounted on the bottom of the movable sleeve 64. Two connecting rods 61 are respectively located at the outer ends of the two connecting sleeves 61 near the movable sleeve 64, with one end of each connecting rod 61 fixedly connected to the movable sleeve 64. The cleaning brush 65 is connected via the reciprocating screw 42. The reciprocating movement can drive the connecting rod 61 and the movable sleeve 64 to move accordingly, so that the cleaning brush 65 at the bottom of the movable sleeve 64 moves back and forth on the top of the non-woven fabric to clean the non-woven fabric, so that impurities on the non-woven fabric are swept out from both sides, improving the continuous hot pressing effect. The fixed seat 62 limits the movement of the movable sleeve 64. The two connecting rods 61 make the two connecting sleeves 51 and the movable sleeve 64 form a whole, so that the geared motor 43 will not rotate when the reciprocating screw 42 rotates, so that the geared motor 43 can move back and forth with the rotation of the reciprocating screw 42, thereby driving the two limit plates 55 and the cleaning brush 65 to move back and forth.

[0022] The functional principle of this application can be explained through the following methods:

[0023] In use, the nonwoven fabric on the take-up roller passes through the bottom of the cleaning brush 65, between the two cleaning brushes 65, the bottom of the tension roller 30, and between the hot press roller of the hot press 20. The geared motor 43 is started, causing its output shaft to drive the reciprocating screw 42 between the two connecting seats 41 to rotate. This causes the reciprocating screw 42 to drive the geared motor 43, which is threaded to its outer side, to reciprocate. The two connecting rods 61 limit the geared motor 43, preventing it from rotating with the reciprocating screw 42. The reciprocating movement of the geared motor 43 drives the two connecting sleeves 51 at both ends to move, causing the connecting sleeves 51 to drive the two limiting plates 55 at the bottom to move. When the two connecting sleeves 51 have reciprocated to their outermost positions, the movement stops. The geared motor 43 rotates the knob 54, causing the threaded rod 53 to move the limiting plate 55 to the side of the nonwoven fabric. This allows the two limiting plates 55 to move precisely to the side of the nonwoven fabric during reciprocating movement. The geared motor 43 is then started, causing the reciprocating screw 42 to rotate, which in turn causes the two limiting plates 55 to reciprocate, straightening the offset nonwoven fabric and preventing it from affecting the hot pressing quality. The two connecting sleeves 51 reciprocate outside the fixed seat 62 via the movable sleeve 64 on the connecting rod 61. This causes the movable sleeve 64 to drive the cleaning brush 65 at the bottom to clean the nonwoven fabric, removing impurities from both sides and preventing them from affecting the hot pressing process.

Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
