Description

Technical Field

[0001] This utility model relates to a bag opening machine, and more particularly, to a laser bag opening machine and its sewing mechanism. Background Technology

[0002] A pocket opening machine is a device specifically designed for sewing pockets. For example, Chinese Patent No. CN216445583U discloses a pocket opening sewing machine for concealed pockets, which includes a frame and a material preparation mechanism, a laser pocket opening mechanism, a pocket folding mechanism, and a sewing machine unit that are sequentially installed on the worktable of the frame.

[0003] When sewing pockets, it is usually necessary to reinforce the joints on both sides of the pocket with tight stitching. When using the above-mentioned sealing machine to reinforce the sides of the pocket, the only way to achieve reinforcement is to move the fabric back and forth repeatedly through the folding mechanism and move the needle in the sewing machine up and down. However, the folding mechanism is relatively heavy. When ordinary screw motors and other drive equipment drive the heavy folding mechanism, it is impossible to guarantee fast and uniform repeated movement, which will have a certain impact on the sewing speed and the appearance of the sewing. Utility Model Content

[0004] In view of this, the first objective of this utility model is to provide a sewing mechanism for a laser bag opening machine, wherein the sewing needle has the function of swinging independently during the sewing process.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a sewing mechanism for a laser bag opening machine, including a machine head housing, a sewing needle assembly and a first drive source are provided inside the machine head housing, the first drive source is used to drive the sewing needle assembly to sew up and down, the machine head housing is also provided with a sewing needle frame and a second drive source, the sewing needle assembly is slidably mounted on the sewing needle frame, the upper end of the sewing needle frame is hinged to the machine head housing, and the second drive source is used to drive the sewing needle frame to swing left and right.

[0006] By using the above-mentioned technical means, the needle frame is driven to swing left and right by the second driving source, and the needle frame and the needle assembly are slidably coordinated to drive the needle assembly to swing left and right while the needle assembly is sewing up and down. When reinforcing the sides of the pocket, there is no need for the folding mechanism to move the fabric repeatedly laterally, which increases the sewing speed and the aesthetics of the sewing.

[0007] Preferably, the needle assembly includes a needle body, a rotating block, a clamp, and a sliding seat. One end of the rotating block is rotatably mounted on the sliding seat. The clamp is fixedly connected to the needle body. The other end of the rotating block is rotatably mounted on the clamp. The first drive source drives the sliding seat to move up and down reciprocally.

[0008] By using the above-mentioned technical means, by setting up a rotating block and a lever clamp, the rotating block and lever clamp are driven to rotate when the needle holder swings, thus preventing the first drive source from swinging with the needle body.

[0009] Preferably, the sliding seat includes a slider and a slide rod, the rotating block is rotatably mounted on the slide rod, a sliding frame is provided inside the machine head housing, and the slider slides up and down on the sliding frame.

[0010] By using the above-mentioned technical means, the accuracy of linear reciprocating motion is increased through the sliding seat and the sliding frame, thereby achieving the purpose of upper and lower sewing.

[0011] Preferably, the first driving source includes a motor, a rotating shaft, a crank, and a rocker arm. The rotating shaft is located at the output end of the motor. One end of the crank is fixed to the rotating shaft, and the other end is rotatably engaged with the top of the rocker arm. The sliding rod is rotatably engaged with the tail of the rocker arm. When the rotating shaft rotates, the slider performs linear reciprocating motion within the sliding frame.

[0012] Through the aforementioned technical means, the rotational motion is changed into linear reciprocating motion by coordinating the rotation shaft, crank, and rocker arm.

[0013] Preferably, the second drive source includes a second motor, a first swing arm, a second rocker arm, a third rocker arm, a second rotating shaft, and a second swing arm. One end of the second swing arm is fixedly mounted on the output end of the second motor, and the other end is rotatably connected to the second rocker arm. The other end of the second swing arm is rotatably connected to the third rocker arm, and the other end of the third rocker arm is fixed to the second rotating shaft. The head of the second swing arm is fixed to the tail of the second rotating shaft, and the tail of the second swing arm slides in conjunction with the needle holder.

[0014] Through the above-mentioned technical means, by cooperating between the second swing arm and the second rotating shaft, and by sliding the tail of the second swing arm with the needle holder, the oscillation of the needle holder can be completed by reciprocating the rotation of the second rotating shaft. Through the cooperation of the first swing arm, the second rocker arm, and the third rocker arm, the transmission between the motor and the second rotating shaft is completed, so that the motor can be installed in other positions, increasing the compactness.

[0015] The second objective of this invention is to provide a bag-opening machine in which the sewing needle has the function of swinging independently during the sewing process.

[0016] A laser bag opening machine includes a frame, a material preparation mechanism, a laser bag opening mechanism, and a bag folding mechanism. A Z-axis drive assembly is provided on the frame, and the sewing mechanism is located at the output end of the Z-axis drive assembly.

[0017] The aforementioned technical means enable the entire head housing to move downwards. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered. Example

[0026] A sewing mechanism for a laser-operated bag-opening machine includes a head housing 1. A needle assembly 2 and a first drive source 3 are disposed within the head housing 1. The first drive source 3 drives the needle assembly 2 to sew up and down. The head housing 1 also includes a needle holder 5 and a second drive source 4. A sliding hole 51 is provided within the needle holder 5, and the needle assembly 2 is slidably disposed on the sliding hole 51. The sliding hole 51 restricts the movement of the needle assembly 2 in the Z-axis direction. The second drive source 4 drives the needle holder 5 to swing left and right. When the needle holder 5 swings, the needle assembly 2 swings along with the needle holder 5, thus eliminating the need for the bag-folding mechanism 93 to repeatedly move the fabric laterally during reinforcement sewing on both sides of the pocket, increasing sewing speed and improving sewing aesthetics.

[0027] One end of the needle holder 5 is hinged to the head housing 1, and the other end is slidably connected to the output end of the second drive source 4. The needle assembly 2 includes a needle body 21, a rotating block 22, a lever clamp 23, and a sliding seat 24. The needle body 21 is slidably engaged with the sliding hole 51. One end of the rotating block 22 is rotatably mounted on the sliding seat 24. The lever clamp 23 is fixedly connected to the needle body 21. The other end of the rotating block 22 is rotatably mounted on the lever clamp 23. The first drive source 3 drives the sliding seat 24 to move up and down reciprocally. By setting the rotating block 22 and the lever clamp 23, the needle holder 5 is made to rotate when it swings, preventing the first drive source 3 from swinging with the needle body 21 and thus preventing jamming. The sliding seat 24 includes a slider 241 and a sliding rod 242. The rotating block 22 is rotatably mounted on the sliding rod 242. The rotation axis of the lever clamp 23 is parallel to the central axis of the sliding rod 242.

[0028] The first drive source 3 includes a motor 31, a rotating shaft 62, a crank 63, and a rocker arm 64. The rotating shaft 62 is located at the output end of the motor 31. One end of the crank 63 is fixed to the rotating shaft 62, and the other end is rotatably engaged with the top of the rocker arm 64. The slide bar 242 is rotatably engaged with the tail of the rocker arm 64. When the rotating shaft 62 rotates, the crank follows the rotating shaft 62. At this time, the rocker arm 64 swings around the rotation center of the rotating shaft 62 and drives the slider 241 to perform linear reciprocating motion in the sliding frame 66, thereby changing the rotational motion into linear reciprocating motion. The accuracy of the linear reciprocating motion is increased by the sliding seat 24 and the sliding frame 66, thereby completing the purpose of sewing the upper and lower parts.

[0029] The second drive source 4 includes a second motor 41, a first swing arm 71, a second rocker arm 72, a third rocker arm 73, a second rotating shaft 74, and a second swing arm 75. One end of the second swing arm 75 is fixedly mounted on the output end of the second motor 41, and the other end is rotatably connected to the second rocker arm 72. The other end of the second swing arm 75 is rotatably connected to the third rocker arm 73, and the other end of the third rocker arm 73 is fixed to the second rotating shaft 74. The head of the second swing arm 75 is fixed to the tail of the second rotating shaft 74. The tail of the second swing arm 75 is provided with a second slider 241, which slides and engages with the needle holder 5. By reciprocating the rotation of the second rotating shaft 74, the needle holder 5 can swing. Through the cooperation between the first swing arm 71, the second rocker arm 72, and the third rocker arm 73, the transmission between the second motor 41 and the second rotating shaft 74 is completed, so that it can be installed at any position on the head housing 1, which can increase the compactness of the equipment. Example

[0030] A laser bag-opening machine includes a frame 9, a material preparation mechanism 91, a laser bag-opening mechanism 92, a bag-folding mechanism 93, and a sewing machine head assembly. The frame 9 is also equipped with a Z-axis drive assembly 94. The sewing mechanism is located at the output end of the Z-axis drive assembly 94, thereby allowing the machine head housing 1 to move downward as a whole. The material preparation mechanism 91 is used to place the bag to be sewn. The laser bag-opening mechanism 92 is used to cut a slit in the garment. The bag-folding mechanism 93 is used to fold the bag to be sewn into the slit. The sewing machine head assembly is used to sew the bag onto the garment.

[0031] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
