Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0038] The purpose of this invention is to provide a zipper release device and an automatic placket opening machine, which effectively improves the shortcomings of relying on experience and manual methods for calibration and positioning.

[0039] It should be noted that in this embodiment, the X direction in the attached drawings is defined as the first direction, and the Y direction is defined as the second direction.

[0040] Please see Figure 1 and Figure 2To achieve the above objectives, this utility model provides a zipper placement device, including a base and a zipper placement plate 100. The base includes a fixed seat 400 for connection to the base plate 300 of a sewing machine, and a rotating seat 500 rotatably connected to the fixed seat 400. The zipper placement plate 100 is connected to the rotating seat 500, and a receiving groove 110 for placing a zipper is provided on one side of the zipper placement plate 100. The receiving groove 110 includes a zipper tail clearance groove 111, a first zipper tooth slot 112, and a first zipper head clearance position 113, which are sequentially connected along the length of the zipper placement plate 100. The zipper tail clearance groove 111 is used to position the tail of the zipper, so that the zipper teeth are laid along the length of the zipper placement plate 100, and the zipper teeth are engaged with the first zipper tooth slot 112, and the zipper head is located in the first zipper head clearance position 113.

[0041] Please see Figure 3 By setting the receiving groove 110 to a structure suitable for accurate zipper positioning, the zipper position is accurately achieved. After aligning the tail of the zipper with the zipper tail clearance groove 111, the zipper is laid along the length of the zipper placement plate 100, and at least part of the zipper teeth are engaged with the first zipper tooth groove 112, thus fixing the zipper position. The first zipper head clearance position 113 is used to accommodate the zipper head, making the zipper flat and allowing the zipper to be fixed relative to the zipper placement plate 100. The engagement between the first zipper tooth groove 112 and the zipper teeth is achieved by the zipper teeth engaging with the first zipper tooth groove 112, where the teeth have a certain outward tension and abut against the inner walls on both sides of the first zipper tooth groove 112 to limit... The zipper can move freely. Furthermore, a second zipper tooth groove and a second zipper head clearance position can be added to the side of the first zipper head clearance position 113 opposite to the first zipper tooth groove 112. The second zipper tooth groove is located between the first zipper head clearance position 113 and the second zipper head clearance position. This allows the zipper placement plate 100 to be suitable for the installation and positioning of longer zippers. Specifically, after aligning the tail of the long zipper with the zipper tail clearance groove 111, the zipper teeth are engaged in the first zipper tooth groove 112 and the second zipper tooth groove, and the zipper head is accommodated in the second zipper head clearance position. The zipper placement plate 100 can adapt to the fixing of zippers of different lengths according to actual needs, improving the versatility of the zipper placement plate 100.

[0042] The zipper placement plate 100 includes a placement plate body with a receiving groove 110 and a sewing clearance groove 120, and a reinforcing plate 200 connected to one side of the placement plate body. The reinforcing plate 200 is used to seal the side of the first zipper tooth groove 112 facing the reinforcing plate 200. When the rotating seat 500 rotates to a first angle relative to the fixed seat 400, the length direction of the zipper placement plate 100 extends along the first direction and the opening of the receiving groove 110 faces upward for placing the zipper. At this time, the reinforcing plate 200 is located below the placement plate body. When the rotating seat 500 rotates to a second angle relative to the fixed seat 400, the length direction of the zipper placement plate 100 extends along the second direction at an angle to the first direction and the opening of the receiving groove 110 faces downward. At this time, the reinforcing plate 200 is located above the placement plate body for the sewing machine to sew the zipper. The zipper placement plate 100 is also provided with a sewing clearance groove 120 adjacent to the receiving groove 110. The length direction of the sewing clearance groove 120 is consistent with the length direction of the zipper placement plate 100, and is used for the machine needle to sew the zipper placed on the zipper placement plate 100 onto the fabric.

[0043] By rotating the rotating seat 500 relative to the fixed seat 400 to a first angle, the length direction of the zipper placement plate 100 extends along the first direction and the opening of the receiving groove 110 faces upward, making it easy to install the zipper from the top of the receiving groove 110 into the receiving groove 110. After the zipper is connected with the receiving groove 110, by rotating the rotating seat 500 relative to the fixed seat 400 to a second angle, the length direction of the zipper placement plate 100 extends along the second direction at an angle to the first direction and the opening of the receiving groove 110 faces downward, making it easy for the sewing machine to sew the zipper. Through the cooperation of the seat and the zipper placement plate 100, the placement, flipping and subsequent sewing of the zipper can be accurately realized, effectively improving the drawbacks of calibration and positioning based on experience and technique.

[0044] Please see Figure 6It should be noted that the sewing clearance groove 120 can be used for sewing fabric strips fixed to one side of the zipper teeth of the zipper placement plate 100. The zipper placement plate 100 includes a first side 130 and a second side 140 opposite each other in its width direction. The sewing clearance groove 120 and the receiving groove 110 are located between the first side 130 and the second side 140, and the first zipper tooth slot 112 is located between the sewing clearance groove 120 and the second side 140. The distance between the first zipper tooth slot 112 and the sewing clearance groove 120 in the width direction of the zipper placement plate 100 is equal to the distance between the first zipper tooth and the first zipper tooth. The distance between the slot 112 and the second side 140 in the width direction of the zipper placement plate 100 allows for the sewing of a strip of fabric on the other side of the zipper teeth of the zipper placement plate 100 to be fixed on the second side 140. The reinforcing plate 200 and the placement plate body can be fixed with screws. The reinforcing plate 200 is provided with a first clearance hole 210 corresponding to the first zipper head clearance position 113 and a second clearance hole 220 corresponding to the second zipper head clearance position. The setting of the first clearance hole 210 and the second clearance hole 220 can prevent the reinforcing plate 200 from interfering with the zipper pull.

[0045] The zipper placement plate 100 also has a clearance surface 160, which is located at one end of the zipper placement plate 100 along its own length direction near the zipper tail clearance groove 111. The clearance surface 160 can be configured such that its projection along the length direction of the zipper placement plate 100 overlaps with the projection of the inner wall of the zipper tail clearance groove 111 along the length direction of the zipper placement plate 100. The clearance surface 160 can be formed by cutting one end of the zipper placement plate 100 along its own length direction near the zipper tail clearance groove 111, so that the fabric strip of the zipper is suspended, making it easy for the entire zipper to be removed from the zipper placement plate 100. The zipper tail clearance groove 111 is provided with a guide slope 170. The guide slope 170 is located at one end of the zipper tail clearance groove 111 away from the first zipper tooth groove 112. The guide slope 170 is set at an angle to the length direction of the zipper placement plate 100. It is used to guide the zipper tail to move into the zipper tail clearance groove 111, making it easier for the zipper tail to slide into the zipper tail clearance groove 111.

[0046] Please see Figure 4 , Figure 5 and Figure 7In one possible implementation, the fixed base 400 is provided with a first connecting portion 410, which has a first through hole 411. The rotating base 500 is provided with a second connecting portion 510, which has a second through hole 511 corresponding to the first through hole 411. A pin 600 passes through the first through hole 411 and the second through hole 511 to allow the rotating base 500 to rotate relative to the fixed base 400. The rotation range of the rotating base 500 relative to the fixed base 400 can be limited by a limiting member. For example, by adding a first limiting member, the rotation range can be limited when the rotating base 500 rotates to a first angle relative to the fixed base 400. The continued rotation of the movable seat 500, that is, the rotation of the movable seat 500 relative to the fixed seat 400 to the first angle is the first limit position of the rotation of the movable seat 500. Similarly, by adding a second limiting member, the continued rotation of the movable seat 500 can be restricted when the movable seat 500 rotates relative to the fixed seat 400 to the second angle. That is, the rotation of the movable seat 500 relative to the fixed seat 400 to the second angle is the second limit position of the rotation of the movable seat 500. The movable seat 500 can rotate relative to the fixed seat 400 within the range between the first angle and the second angle. The limitation of the rotation angle by the limiting member is a technology well known to those skilled in the art, and will not be described in detail here.

[0047] In one possible embodiment, the rotating base 500 further includes a third connecting portion 520 for connecting with the zipper placement plate 100. The third connecting portion 520 has a first mounting hole 521, and the zipper placement plate 100 has a second mounting hole 180. A connector is connected to the first mounting hole 521 and the second mounting hole 180 to fix the rotating base 500 and the zipper placement plate 100 relatively. The first mounting hole 521 and the second mounting hole 180 can be threaded holes, and the connector can be a screw. The number of both the first mounting hole 521 and the second mounting hole 180 is set to two to facilitate the installation and removal of the zipper placement plate 100 and the rotating base 500.

[0048] It should be noted that the third connecting part 520 is provided with a first plane, and the first plane has the aforementioned first mounting hole 521. The zipper placement plate 100 is provided with a second plane, and the second plane has the aforementioned second mounting hole 180. The first plane and the second plane abut against each other after the connector is connected to the first mounting hole 521 and the second mounting hole 180, in order to ensure the stable connection between the zipper placement plate 100 and the rotating seat 500.

[0049] Furthermore, the third connecting portion 520 is provided with a third plane parallel to the first plane, and there are two second connecting portions 510, with the two second connecting portions 510 protruding from the third plane. The two second connecting portions 510 are spaced apart to form a clearance groove, which is used to accommodate the first connecting portion 410 and form a rotation space for the rotating seat 500 relative to the fixed seat 400, so as to avoid motion interference between the rotating seat 500 and the fixed seat 400.

[0050] In one possible implementation, the angle between the axis of the pin 600 and the first direction is equal to the angle between the axis of the pin 600 and the second direction. The axis of the pin 600 can be set to be parallel to the base plate 300, and the angle between the axis of the pin 600 and the first direction and the angle between the axis of the pin 600 and the second direction are both 45°. When the rotating seat 500 rotates relative to the fixed seat 400 to the first angle (the first plane is parallel to the base plate 300 and is located above the fixed seat 400), the zipper placement plate 100 is in a horizontal state and the opening of the receiving groove 110 faces upward. When the rotating seat 500 rotates relative to the fixed seat 400 to the second angle (the first plane is parallel to the base plate 300 and is located below the fixed seat 400), the zipper placement plate 100 is also in a horizontal state and the opening of the receiving groove 110 faces downward, so as to realize the transformation of the zipper placement plate 100 from the zipper placement state to the sewing-ready state.

[0051] Based on the above, this application also provides an automatic placket opening machine, including a base plate 300 and a zipper placement device. A fixing seat 400 is connected to the base plate 300. This connection method can be a direct connection or an indirect connection, which can realize the zipper placement plate 100 switching back and forth between the zipper placement state and the sewing state. The remaining structure of the automatic placket opening machine can refer to the prior art, and will not be described in detail here.

[0052] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0053] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0054] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
