Description

Technical Field

[0001] The utility model relates to the technical field of zipper production equipment, in particular to a slider chain closing device and an automatic slider chain threading and closing machine. Background Art

[0002] The existing zipper has a pull head and a chain belt, and the chain belt has a first chain belt and a second chain belt. The first end of the first chain belt has a square, and the first end of the second chain belt has a latch inserted into the square. During production, the pull head and the chain belt are produced separately. After production, the pull head and the chain belt need to be pulled together before they can be sold. The traditional zipper is pulled and closed by manually installing the pull head on the chain belt, which is inefficient. Later, a mechanized operation was adopted, that is, the pull head was installed on the chain belt through a chain closing machine. However, the working method of this chain closing machine is that after the chain belt is unwound for a certain length, the pull head is straightly installed on the first chain belt, and then the pull head is straightly installed in the second chain belt so that the latch is inserted into the square of the first chain belt to close the first chain belt and the second chain belt. However, in actual production, when the pull head is installed from the end of the second chain belt, the position of the latch is prone to deviation due to the elasticity of the cloth tape on the chain belt, causing the latch to be unable to smoothly penetrate into the pull head, thereby requiring manual maintenance and adjustment operations, resulting in low production efficiency.

[0032] Example 1

[0033] This embodiment provides a pull head chain closing device, such as Figure 1 As shown, it includes a pin end insertion mechanism 1, a block end insertion mechanism 2 and a pull-back mechanism 3, all of which are arranged on the path of the chain belt 5; the chain belt 5 is driven forward by the transmission mechanism of the prior art.

[0034] The block end insertion mechanism 2 is used to insert the first chain belt 51 with the block 511 into the slider. The block end insertion mechanism 2 can be realized by the prior art and is not limited too much. It can realize the first chain belt 51 with the block 511 to be inserted into the slider.

[0035] The bolt end insertion mechanism 1 comprises a detection module, a first cylinder 11 and a fabric core hook 12.

[0036] The movable end of the first cylinder 11 is connected to the fabric core hook 12;

[0037] The detection module is used to detect the position where the latch 521 stops;

[0038] The cloth core hook 12 is arranged vertically toward the path of the chain belt 5, and is used to flip the cloth core 522 at the rear end of the pin 521 downward to adapt the positioning of the pin 521 and the pull head; when the second chain belt 52 moves forward, when the sprocket on the second chain belt 52 reaches the detection module, the detection module is triggered due to the height difference between the sprocket and the cloth belt, and after the controller receives the signal, it determines the position where the pin stays, waiting for the first cylinder 11 and the cloth core hook 12 to complete the hook and pull operation.

[0039] The pull-back mechanism 3 is used to insert the second chain belt 52 with the latch 521 into the pull head, and drive the latch 521 to be spliced ​​with the block 511 .

[0040] In this embodiment, if Figure 2 As shown, the latch end insertion mechanism 1 also includes a second cylinder 13 and a clamping block 14 for moving the second chain belt 52 closer to the pull head. The clamping block 14 is connected to the movable end of the second cylinder 13 to cooperate with the latch end insertion mechanism 1 and the pulling mechanism 3 after the positioning of the adaptable latch 521 and the pull head.

[0041] In this embodiment, if Figure 2 As shown, the clamp block 14 is provided with a U-shaped groove for the second chain belt 52 to pass through, so as to improve the stability of the second chain belt 52 and avoid excessive elastic deformation of the cloth belt.

[0042] In this embodiment, if Figure 1 As shown, the pulling back mechanism 3 includes a third cylinder 31 for locking the belt, a fourth cylinder 32 for inserting and a movable seat 33. The third cylinder 31 is arranged on the movable seat 33, and the movable end of the third cylinder 31 is arranged vertically toward the path of the chain belt 5. The movable seat 33 is slidably connected to the slide rail and the movable seat 33 is connected to the movable end of the fourth cylinder 32. That is, after the third cylinder 31 locks the second chain belt 52, the fourth cylinder 32 pulls back the second chain belt.

[0043] In this embodiment, if Figure 3 One side of the movable seat 33 is connected to the movable end of the fourth cylinder 32, and the other side of the movable seat 33 is connected to a buffer spring 34, wherein the buffer spring 34 plays a role of buffering and unloading force. When the bolt is inserted, it is ensured that the distance between the position where the bolt is positioned and stopped after it is inserted into place is less than the movable stroke of the fourth cylinder 32, that is, after the bolt is inserted into place, the fourth cylinder 32 allows the stroke to be pulled back before it is in place, and the remaining stroke will be compressed and absorbed by the buffer spring 34 to ensure the stability of the insertion action.

[0044] In this embodiment, if Figure 2 As shown, the block end insertion mechanism 2 includes a fifth cylinder 21 and a protrusion 22 connected to the movable end of the fifth cylinder 21, the protrusion 22 is arranged vertically toward the path of the chain belt 5 and is arranged adjacent to the fabric core hook 12; the fabric core hook 12 and the protrusion are arranged in sequence along the path of the chain belt 5, and when the first chain belt is inserted into the slider to complete the insertion, since some zippers do not have an upper stop end 512 (such as Figure 4 As shown), the first chain belt 51 may be unstable or stuck when inserted. Then the protrusion 22 may be used to squeeze the first chain belt 51 to allow the first chain belt 51 to be inserted more smoothly, thereby improving stability. When not in use, the protrusion 22 may be shielded and not act.

[0045] In this embodiment, the block end insertion mechanism 2 also includes a sensor for detecting the position where the block 511 stops, that is, to ensure that the transmission mechanism drives the zipper to move forward so that the block will stay at the set position after passing through the upper stop end positioning.

[0046] In this embodiment, if Figure 2As shown, the detection module includes a detection piece 15 and a sensor 16 electrically connected to the detection piece 15. The detection piece 15 is arranged adjacent to the cloth core hook 12. The sensor 16 is electrically connected to the controller. When the second chain belt 52 moves forward, when the sprocket on the second chain belt 52 reaches the detection module, the detection piece 15 is triggered due to the height difference between the sprocket and the cloth belt. After the sensor 16 receives the signal, it determines the position where the pin stops, and the controller drives the first cylinder 11 and the cloth core hook 12 to complete the hook pulling operation.

[0047] In this embodiment, a slider lower mold mechanism 35 is also included, which is used to provide a slider and is arranged on the chain belt path at the interval between the plug-end insertion mechanism 1 and the block-end insertion mechanism 2 to cooperate with the pin-end insertion mechanism 1 and the block-end insertion mechanism 2.

[0048] Working principle: After one side of the slider completes the first penetration under the action of the block end penetration mechanism 2, after the detection piece 15 of the pin end penetration mechanism 1 detects that the pin 521 is in place, the first cylinder 11 drives the cloth core hook 12 to flip the cloth core 522 at the rear end of the pin downward to adapt to the positioning of the pin 521 and the slider, the fourth cylinder 31 and the fifth cylinder 32 penetrate the second chain belt 52 with the pin into the slider, and drive the pin 521 to splice with the block 511, so that the first chain belt 51 and the second chain belt 52 penetrate the slider and the pin 521 is smoothly combined with the block 511, so as to avoid the problem that the position of the pin 521 is easily deviated due to the elasticity of the cloth belt on the chain belt, which causes the pin to fail to penetrate the slider smoothly.

[0049] This embodiment also provides an automatic pull-head chain-closing machine, which includes a chain belt transmission mechanism, a feeding mechanism and a pull-head chain-closing device.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
