Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a needle loom. Background Art

[0002] Needle-punched nonwoven fabric is a type of dry-laid nonwoven fabric. Short fibers are opened, combed, and laid into a fiber web, and then the fiber web is reinforced into cloth through a needle. The needle has barbs, which repeatedly puncture the fiber web, and the hook-belt fibers are reinforced to form a needle-punched nonwoven fabric.

[0003] However, the needle punching machines commonly used in the market currently require the needles to be frequently raised and lowered in the short fibers during the needling process of non-woven fabrics. The needles are easily heated by friction with the short fibers during the rapid raising and lowering process. The needles are easily deformed after long-term use, which can easily affect the product quality during the subsequent needling process. Therefore, there is room for improvement. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a needling machine, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a needling machine, comprising a base, a conveying platform is arranged on the base, brackets are arranged on both sides of the conveying platform, a needling drum is arranged on the bracket, connecting rods are arranged at both ends of the needling drum, a reciprocating cylinder is arranged on the bracket, a fixed ring is arranged at the output end of the reciprocating cylinder, the connecting rod is inserted in the fixed ring, driving devices for driving the needling drum to rotate are arranged at both ends of the needling drum, a connecting row is arranged on the side wall of the needling drum, and needles are arranged at the end of the connecting row away from the needling drum.

[0006] By adopting the above-mentioned technical method, when the needling machine in the present application is in use, the operator places the fabric to be needled on the conveying platform, and the conveying platform drives the fabric to move. During the movement of the fabric, the operator can set the rotation time and frequency of the driving device, and control the frequency of needling of each row of needles based on the rotation time of the needling drum driven by the driving device, so as to needle the fabric through multiple groups of needling rotation, thereby reducing the frictional heat generated between the same group of needles and the short fibers, making it easy for the needles to deform after long-term use.

[0007] As a preferred technical solution of the present invention, a connecting rod is provided at the output end of the reciprocating cylinder, the fixing ring is provided at the end of the connecting rod away from the reciprocating cylinder, a first mounting rod is provided on the side wall of the connecting rod, a second mounting rod is provided at the end of the first mounting rod away from the connecting rod, and a sensing device is provided at the end of the second mounting rod away from the first mounting rod, and the sensing device is electrically connected to the reciprocating cylinder.

[0008] By adopting the above technical method, the sensing device is used to monitor the rotation of the needling drum. When the needling drum needs to be rotated according to the program set by the system and the needles are replaced, the sensing device can detect the rotation position of the needling drum. When the needling drum rotates to the appropriate position, the sensing device drives the reciprocating cylinder to drive the needling drum to fall, so as to complete the needling of the fabric.

[0009] As a preferred technical solution of the present invention, the sensing device includes a sensing plate, a sensing input structure and a sensing output structure, the sensing plate is arranged at an end of the second mounting rod away from the first mounting rod, the sensing plate is provided with a sensing groove on the end wall close to the needling roller, the sensing input structure is arranged in the sensing groove, the sensing output structure is arranged on the end wall of the needling roller, and the sensing output structure is electrically connected to the sensing output structure.

[0010] By adopting the above-mentioned technical method, the sensing plate is arranged on one side of the needling drum. When the needling drum rotates, the sensing output structure located on the end wall of the needling drum can send out a signal, and receive the signal through the sensing input structure located in the sensing groove. When the sensing input structure receives the signal, it means that the rotation angle of the needling drum has been in place, and the fabric can continue to be woven.

[0011] As a preferred technical solution of the present invention, a mounting groove is provided on the side wall of the needling drum, the connecting row is inserted into the mounting groove, the connecting row and the mounting groove are detachably connected, and a fixing structure for fixing the connecting row is provided in the mounting groove.

[0012] By adopting the above technical method, the operator can install and replace the needles by installing the connecting row in the installation groove. Compared with replacing the acupuncture drum as a whole, the use of a fixed structure to insert the installation row on the side wall of the acupuncture drum saves costs.

[0013] As a preferred technical solution of the present invention, the fixing structure includes a locking spring and a locking block, locking holes are provided on the side walls at both ends of the mounting groove, the locking holes are connected to the mounting groove, the locking spring is inserted into the locking hole, the locking spring is arranged on the end wall of the locking hole, the locking block is arranged at one end of the locking spring, and a fixing hole is provided on the side wall of the connecting row, and the locking block is inserted into the fixing hole.

[0014] By adopting the above technical method, when the operator needs to replace the needle, the operator can insert the connecting row into the installation groove and move the locking block toward the direction of the locking spring, so that the locking spring is compressed. When the connecting row is fully inserted into the installation groove, the locking spring rebounds and drives the locking block to be inserted into the fixing hole, thereby completing the installation of the connecting row.

[0015] As a preferred technical solution of the present invention, when one end of the locking block close to the fixing hole is inserted into the fixing hole, the other end of the locking block away from the fixing hole is inserted into the locking hole.

[0016] By adopting the above technical method, when the locking block is inserted into the fixing hole to complete the installation of the connecting row, the end of the locking block away from the fixing hole is set in the locking hole, so that the connecting row can be fixed by the locking block, thereby improving the stability of the connecting row inserted in the installation groove.

[0017] As a preferred technical solution of the present invention, a guide surface is provided on the side wall of the locking block close to the connecting row, the connecting row abuts against the side wall of the guide surface, and the guide surface is inclined toward the direction of the connecting row. When the connecting row abuts against the side wall of the guide surface, the locking spring is compressed.

[0018] By adopting the above-mentioned technical method, the structure of the guide surface can ensure that when the operator inserts the connecting row into the installation groove, the side wall of the connecting row will first abut against the side wall of the guide surface. As the connecting row is gradually inserted into the installation groove, the locking block will be abutted against the locking hole until the locking block rebounds into the fixing hole. The installation of the connecting row can be completed, which improves the convenience of the operator during installation.

[0019] As a preferred technical solution of the present invention, a plurality of the needling rollers are provided, and the plurality of the needling rollers are arranged along the conveying direction of the conveying platform.

[0020] By adopting the above technical method, a plurality of needling rollers work together for needling, which further improves the needling efficiency.

[0021] As a preferred technical solution of the present invention, a detection rod is arranged on the side wall of the connecting rod, and a detection tooth is arranged on the side wall of the detection rod away from the connecting rod, the detection tooth and the needle are staggered, the detection tooth is typically connected to the conveying device, and the detection tooth and the needle are staggered.

[0022] By adopting the above technical method, the detection teeth and the needles are staggered, so that when the needles are deformed, the needles will generate friction with the detection teeth during rotation. When the detection teeth detect friction or collision, the system can stop working, thereby reducing the possibility of product quality being affected by the deformation of the needles.

[0023] Beneficial effects of the present invention:

[0024] 1. When the needling machine in the present application is in use, the operator places the fabric to be needled on the conveying platform, and the conveying platform drives the fabric to move. During the movement of the fabric, the operator can set the rotation time and frequency of the driving device, and control the frequency of needling of each row of needles based on the rotation time of the needling drum driven by the driving device, so as to needle the fabric through multiple groups of needling rotation, thereby reducing the frictional heat generated between the same group of needles and the short fibers, making it easy for the needles to deform after long-term use.

[0025] 2. The induction plate is arranged on one side of the needling drum. When the needling drum rotates, the induction output structure on the end wall of the needling drum can send out a signal, and receive the signal through the induction input structure in the induction slot. When the induction input structure receives the signal, it indicates that the rotation angle of the needling drum has been reached, and the fabric can continue to be woven.

[0026] 3. By staggered arrangement of the detection teeth and the needles, when the needles are deformed, friction will occur between the detection teeth during rotation. When the detection teeth detect friction or collision, the system can stop working, thereby reducing the possibility of product quality being affected by needle deformation.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 - Figure 3 A needling machine 1 includes a base 11, which is vertically arranged. A clamping roller is arranged on one side of the base 11. When the fabric needs to be needled, the operator clamps the fabric between a pair of clamping rollers and clamps the fabric through the pair of clamping rollers. The fabric will be driven to move with the rotation of the pair of clamping rollers.

[0034] Reference Figure 1 and Figure 2 A conveying platform 12 is installed on the top wall of the base 11, and a bracket 13 is welded and fixed on the top wall of the conveying platform 12, and a pair of brackets 13 are provided, and the brackets 13 are respectively arranged on both sides of the conveying platform 12. A reciprocating cylinder 16 is fixedly installed on the bottom wall of the bracket 13 by bolts, and a connecting rod 2 is welded and fixed on the output end of the reciprocating cylinder 16, and a fixing ring 17 is integrally formed at one end of the connecting rod 2 away from the reciprocating cylinder 16. A pair of reciprocating cylinders 16, connecting rods 2 and fixing rings 17 are provided, and a pair of reciprocating cylinders 16 are respectively arranged on both sides of the bracket 13. The axis of the pair of fixing rings 17 is located on the same connecting line. A needling roller 14 is provided between the pair of fixing rings 17, and the needling roller 14 is rotatably connected to the fixing ring 17. A plurality of rows of needles are evenly arranged on the side wall of the needling roller 14 for needling the fabric on the conveying platform 12. The needle punching drum 14 rotates so that different needles can be used to needle the fabric, thereby reducing the frictional heat between the needles of the same group and the short fibers, thereby reducing the possibility of deformation of the needles after long-term use.

[0035] Reference Figure 3 and Figure 4 The needling drum 14 is a cylindrical structure. A mounting groove 4 is provided on the side wall of the needling drum 14 along the length direction. A connecting row 19 is inserted in the mounting groove 4. Needles are welded and fixed on the side wall of the connecting row 19. The operator can fix the needles by fixing the connecting row 19 in the mounting groove 4. A locking hole 43 is provided on the inner side wall of the mounting groove 4. The length direction of the locking hole 43 is consistent with the length direction of the mounting groove 4, and a fixing structure for fixing the connecting row 19 is provided in the locking hole 43. The fixing structure includes a locking spring 41 and a locking block 42. The locking spring 41 is provided in the locking hole 43, and the locking spring 41 is welded and fixed to the bottom wall of the locking hole 43. The elastic force direction of the locking spring 41 is consistent with the length direction of the locking hole 43, and the side wall of the locking block 42 is welded and fixed to the locking spring 41. A fixing hole 44 is opened on the side wall of the connecting row 19 near the locking block 42. When the connecting row 19 is inserted into the mounting groove 4, the fixing hole 44 is connected to the locking hole 43, so that the locking spring 41 can push the locking block 42 into the fixing hole 44 to complete the fixed connection between the connecting row 19 and the mounting groove 4.

[0036] Reference Figure 3 and Figure 4 When the locking block 42 is pushed into the fixing hole 44 by the locking spring 41, the end of the locking block 42 close to the fixing hole 44 is inserted into the fixing hole 44, and the end of the locking block 42 away from the fixing hole 44 is inserted into the locking hole 43. When the locking block 42 is inserted into the fixing hole 44 and the installation of the connecting row 19 is completed, the end of the locking block 42 away from the fixing hole 44 is set in the locking hole 43, so that the connecting row 19 can be fixed by the locking block 42, thereby improving the stability of the connecting row 19 inserted in the installation slot 4. A guide surface 5 is provided at one end of the locking block 42 close to the fixing hole 44, and the guide surface 5 is an inclined surface. The guide surface 5 is inclined toward the direction in which the connecting row 19 is inserted. When the operator needs to install the connecting row 19 in the installation groove 4, the connecting row 19 can be held and inserted into the installation groove 4. At this time, the side wall of the connecting row 19 abuts against the side wall of the guide surface 5. As the connecting row 19 is gradually inserted into the installation groove 4, the locking block 42 will be abutted against the locking hole 43 until the locking block 42 rebounds back into the fixing hole 44, and the installation of the connecting row 19 is completed, which improves the convenience of the operator during installation.

[0037] Reference Figure 3 and Figure 4, a plurality of brackets 13 are provided, and a plurality of brackets 13 are arranged flush on the base 11, and a plurality of brackets 13 together needle punch the fabric on the conveying platform 12, and a driving device 18 for driving the needle punching drum 14 to rotate is provided on each bracket 13, and the driving device 18 is selected as a servo motor, and the driving device 18 is slidably connected to the side wall of the bracket 13. A sensing device is provided on the side of the needle punching drum 14 away from the driving device 18, and the sensing device is used to sense whether the servo motor rotates in place when driving the needle punching rolling rotation.

[0038] Reference Figure 1 and Figure 2 The sensing device includes a sensing plate 3, a sensing input structure 31 and a sensing output structure 32. A first mounting rod 21 is welded and fixed on the side wall of the connecting rod 2, and the first mounting rod 21 is vertically arranged to the connecting rod 2. A second mounting rod 22 is welded and fixed on the side wall of the first mounting rod 21 away from the connecting rod 2, and the second mounting rod 22 is arranged parallel to the connecting rod 2. The sensing plate 3 is welded and fixed to one end of the second mounting rod 22 away from the first mounting rod 21, so the sensing plate 3 can move up and down with the movement of the reciprocating cylinder 16. A sensing groove 33 is provided on the side wall of the sensing plate 3 close to the needling drum 14, a sensing input structure 31 is arranged in the sensing groove 33, and a sensing output structure 32 is installed on the side wall of the needling drum 14. The sensing input structure 31 is preferably a photoelectric gate input end, and the sensing output structure 32 is preferably a photoelectric gate output end. When the sensing input structure 31 and the sensing output structure 32 sense each other, it indicates that the needling drum 14 has rotated into place, that is, the needles on the connecting row 19 at the bottom of the needling drum 14 are arranged vertically to the conveying platform 12, so as to facilitate the needling drum 14 to perform subsequent needling operations.

[0039] A detection rod 51 is welded and fixed on one side of the bracket 13, and a detection tooth 52 is welded and fixed on the side wall of the detection rod 51 close to the needling drum 14, and the detection teeth 52 are staggered with the needles on the connecting row 19. Therefore, when the needles are deformed, the needles will rub against the detection teeth 52 during rotation. When the detection teeth 52 detect friction or collision, the system can stop working, thereby reducing the possibility of product quality being affected by needle deformation.

[0040] Working principle: When the needle loom 1 in the present application is in use, the operator can place the fabric on the conveying platform 12, and start the conveying platform 12 and the reciprocating cylinder 16, so that the reciprocating cylinder 16 drives the needle roller 14 to needle the fabric on the conveying platform 12. When the needles on the same group of connecting rows 19 have reached a certain number of needle punches, the operator can drive the drive device 18 to drive the needle roller 14 to rotate. When the induction input device and the induction application device are coupled, the drive device 18 stops working. At this time, the needles are perpendicular to the conveying platform 12, and the needles on the new connecting row 19 continue to needle the fabric. The needle loom 1 in the present application reduces the frictional heat between the needles in the same group and the short fibers, making it easy for the needles to deform after long-term use.
