Description

Technical Field

[0001] This utility model relates to the field of clothing technology, and in particular to a zipper release device and an automatic placket opening machine. Background Technology

[0002] Pants are a type of clothing, typically featuring a fly and a zipper. The zipper stitching process at the fly is relatively complex, requiring frequent folding to form the trouser panels, and the panel positions need to be adjusted according to the zipper's location to create a neat seam.

[0003] In the current technology, zippers for trouser fly are sewn manually. This requires a high level of experience from the operator, who needs to frequently calibrate and position them based on experience and technique. The zipper sewing precision is low, making it difficult to form beautiful stitches. The operation is inefficient, the operator's labor intensity is high, and the probability of producing defective products is relatively high.

[0004] Therefore, how to effectively improve the drawbacks of relying on experience and techniques for zipper position calibration and positioning is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a zipper release device and an automatic placket opening machine, which can effectively improve the shortcomings of relying on experience and manual methods for zipper position calibration and positioning.

[0006] To achieve the above objectives, this utility model provides a zipper release device, comprising:

[0007] A base body for connecting the base plate of a sewing machine. The base body includes a fixed base and a rotating base rotatably connected to the fixed base via a pin. The fixed base is provided with a limiting hole, and the rotating base is provided with a limiting element.

[0008] The zipper placement plate is connected to the rotating base. The first side of the zipper placement plate has a receiving groove for placing zippers. The zipper placement plate can rotate around the pin to the working state where the first side is parallel to the bottom plate and the inlet of the receiving groove faces downward. It also drives the limiting member of the rotating base to engage with the limiting hole to maintain the working state.

[0009] In one possible implementation, the limiting member includes a housing, an elastic member, and a limiting protrusion. The housing has a cavity and a first opening communicating with one side of the cavity. The elastic member and the limiting protrusion are located inside the cavity. One end of the elastic member abuts against the inner wall of the cavity on the side away from the first opening, and the other end of the elastic member abuts against the limiting protrusion to drive the limiting protrusion to protrude from the first opening.

[0010] In one possible implementation, the rotating seat is provided with a fixing hole with an internal thread, and the housing is provided with an external thread adapted to the internal thread in the circumferential direction, so that the housing can be detachably screwed into the rotating seat and the first opening faces the fixing seat.

[0011] In one possible implementation, the fixed seat is provided with a first connecting part, and the rotating seat includes a second connecting part and a third connecting part connected to each other. The second connecting part is used to be rotatably connected to the first connecting part, and the third connecting part is used to be fixed to the zipper placement plate. There are two second connecting parts, and the two second connecting parts protrude from the side of the third connecting part away from the zipper placement plate. The two second connecting parts are spaced apart to form a clearance groove, which is used to accommodate part of the first connecting part.

[0012] In one possible implementation, the limiting member is connected to the second connecting portion, and the limiting member corresponds one-to-one with the second connecting portion.

[0013] In one possible implementation, the axis of the limiting hole is parallel to the axis of the pin, and the fixing seat is also provided with abutment surfaces located at both ends of the limiting hole in its own axial direction. The abutment surfaces are used to abut against the portion of the limiting protrusion that protrudes from the first opening.

[0014] In one possible implementation, the limiting protrusion is a spherical structure, and the abutment surface is an annular curved surface adapted to the limiting protrusion.

[0015] In one possible implementation, a connecting assembly is provided between the base and the bottom plate, the connecting assembly including:

[0016] Lift the base to connect it to the base plate;

[0017] The lifting fixing plate is rotatably connected to the lifting base and can be lifted relative to the base plate. The fixing base is connected to the lifting fixing plate.

[0018] In one possible implementation, the connection component further includes a leveling component, which includes:

[0019] Connection holes are provided for lifting the fixing plate;

[0020] An adjusting component is inserted through the connecting hole and threadedly connected to the connecting hole. The end of the adjusting component facing the lifting base has an abutment. The abutment is used to abut against the lifting base to adjust the angle between the lifting fixing plate and the base plate, so that when the limiting component is engaged with the limiting hole, the first side of the zipper placement plate is parallel to the base plate.

[0021] Based on the above, this application also provides an automatic placket opening machine, including a base plate and any one of the zipper dispensing devices, with a fixing seat connected to the base plate.

[0022] Compared with the prior art, the technical solution provided by this utility model has at least the following beneficial effects: by rotating the rotating seat relative to the fixed seat around the axis of the pin, the zipper placement plate connected to the rotating seat can be driven to rotate synchronously around the axis of the pin. The zipper placement plate can rotate around the pin until the first side is parallel to the base plate, and the inlet of the receiving groove opened on the first side is in a downward working state, so as to be used for the sewing of the zipper by the needle of the subsequent sewing machine. The fixed seat is provided with a limiting hole, and the rotating seat is provided with a limiting member. When the zipper placement plate is in the working state, the limiting member is engaged with the limiting hole to stabilize the zipper placement plate in the working state, thereby stabilizing the position of the zipper. The cooperation between the seat and the zipper placement plate can effectively improve the drawbacks of calibrating and positioning the zipper position by relying on experience and manual methods.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0045] 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.

[0046] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc., 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.

[0047] The purpose of this invention is to provide a zipper release device and an automatic placket opening machine, which can effectively improve the shortcomings of relying on experience and manual methods for zipper position calibration and positioning.

[0048] Please see Figure 1 , Figure 2 and Figure 10 To achieve the above objectives, this utility model provides a zipper placement device, including a base and a zipper placement plate 100. The base is used to connect to the base plate 300 of a sewing machine. The base includes a fixed seat 400 and a rotating seat 500 rotatably connected to the fixed seat 400 via a pin 600. The fixed seat 400 is provided with a limiting hole 412, and the rotating seat 500 is provided with a limiting member 530. The zipper placement plate 100 is connected to the rotating seat 500. The first side 130 of the zipper placement plate 100 is provided with a receiving groove 110 for placing zippers. The zipper placement plate 100 can rotate around the pin 600 to a working state where the first side 130 is parallel to the base plate 300 and the inlet of the receiving groove 110 faces downwards, and drives the limiting member 530 of the rotating seat 500 to engage with the limiting hole 412 to maintain the working state.

[0049] Please see Figure 7 , Figure 8 and Figure 9 The axis of the pin 600 can be set to be parallel to the base plate 300. 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 placement plate body has the first side 130 and a second side 140 opposite to the first side 130. The reinforcing plate 200 is connected to the second side 140 of the placement plate body. 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 that are connected sequentially along the length direction 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 direction of the zipper placement plate 100 and the teeth are engaged with the first zipper tooth slot 112, and the head of the zipper is located in the first zipper head clearance position 113.

[0050] By setting the receiving groove 110 to a structure suitable for accurate zipper positioning, the zipper position is made accurate. 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 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 engagement. 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.

[0051] The reinforcing plate 200 is used to seal the side of the first zipper tooth groove 112 facing the reinforcing plate 200. When the zipper placement plate 100 is in the working state, the reinforcing plate 200 is located above the placement plate body, and the second side 140 of the placement plate body is parallel to the base plate 300. The zipper placement plate 100 in the working state is used by 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 to the fabric. 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 head.

[0052] By rotating the rotating base 500 relative to the fixed base 400 around the axis of the pin 600, the zipper placement plate 100 connected to the rotating base 500 can be driven to rotate synchronously around the axis of the pin 600. The zipper placement plate 100 can rotate around the pin 600 until the first side 130 is parallel to the base plate 300, and the inlet of the receiving groove 110 opened on the first side 130 is in a downward working state for the subsequent sewing machine needle to sew the zipper. The fixed base 400 is provided with a limiting hole 412. The rotating base 500 is equipped with a limiting member 530. When the zipper placement plate 100 is in the working state, the limiting member 530 engages with the limiting hole 412 to stabilize the zipper placement plate 100 in the working state, thereby stabilizing the position of the zipper. The cooperation between the base and the zipper placement plate 100 can effectively improve the drawbacks of calibrating and positioning the zipper position by relying on experience and manual techniques. In other words, it can effectively avoid problems such as low operating efficiency, high labor intensity of operators, and a high probability of producing defective products.

[0053] 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 tail of the zipper into the zipper tail clearance groove 111, making it easier for the tail of the zipper to slide into the zipper tail clearance groove 111.

[0054] Please see Figure 3 , Figure 4 and Figure 5 In one possible implementation, the limiting member 530 includes a housing 531, an elastic member, and a limiting protrusion 532. The housing 531 has a cavity and a first opening communicating with one side of the cavity. The elastic member and the limiting protrusion 532 are located inside the cavity. One end of the elastic member abuts against the inner wall of the cavity on the side away from the first opening, and the other end of the elastic member abuts against the limiting protrusion 532 to drive the limiting protrusion 532 to partially protrude from the first opening. The elastic member may be a spring. The cross-sectional dimension of the first opening perpendicular to the driving direction of the elastic member is smaller than the maximum cross-sectional dimension of the limiting protrusion 532 perpendicular to the driving direction of the elastic member, so as to prevent the limiting protrusion 532 from completely dislodging from the cavity.

[0055] In one possible implementation, the rotating seat 500 is provided with a fixing hole 512, the fixing hole 512 is provided with an internal thread, and the housing 531 is provided with an external thread adapted to the internal thread in the circumferential direction, so that the housing 531 can be detachably screwed into the rotating seat 500, and the first opening faces the fixing seat 400. That is, the end of the housing 531 with the first opening is first screwed into the fixing hole 512, and then the rotation continues to make the first opening reach a preset position, so that it can be used for the subsequent engagement of the limiting protrusion 532 and the limiting hole 412.

[0056] The fixed base 400 is provided with a first connecting part 410, and the rotating base 500 includes a second connecting part 510 and a third connecting part 520 connected to each other. The second connecting part 510 is used to rotatably connect with the first connecting part 410. Specifically, the first connecting part 410 is provided with a first through hole 411, and the second connecting part 510 is provided with a second through hole 511 corresponding to the first through hole 411. The pin 600 passes through the first through hole 411 and the second through hole 511 so that the rotating base 500 can rotate relative to the fixed base 400. The third connecting part 520 is used to fix with the zipper placement plate 100. Specifically, the third connecting part 520 is provided with a first mounting hole 521, and the zipper placement plate 100 is provided with a second mounting hole 180. The connector is connected to the first mounting hole 521 and the second mounting hole 180 so that the rotating base 500 and the zipper placement plate 100 are relatively fixed. The first mounting hole 521 and the second mounting hole 180 can be threaded holes, and the connecting parts can be screws. The number of the first mounting hole 521 and the second mounting hole 180 is set to two, which facilitates the installation and removal of the zipper placement plate 100 and the rotating seat 500.

[0057] Two second connecting portions 510 are provided, and the two second connecting portions 510 protrude from the side of the third connecting portion 520 away from the zipper placement plate 100. The two second connecting portions 510 are spaced apart to form a clearance groove, which is used to accommodate part of the first connecting portion 410. The clearance groove forms a rotation space for the rotating seat 500 relative to the fixed seat 400 to avoid interference between the movement of the rotating seat 500 and the fixed seat 400. The limiting member 530 is connected to the second connecting portion 510, and the limiting member 530 corresponds to the second connecting portion 510 one by one. The axis of the limiting hole 412 is parallel to the axis of the pin 600. The fixed seat 400 is also provided with an abutment surface 420, which is located at both ends of the limiting hole 412 in its own axial direction. The abutment surface 420 is used to abut against the portion of the limiting protrusion 532 protruding from the first opening. Two limiting members 530 are respectively engaged with the two ends of the limiting hole 412 to restrict the relative rotation of the rotating seat 500 and the fixed seat 400, ensuring that the zipper placement plate 100 can maintain its working state. Preferably, the limiting protrusion 532 is configured as a spherical structure, and the abutment surface 420 is an annular curved surface adapted to the limiting protrusion 532. The spherical structure facilitates the limiting protrusion 532 to contact with other components and be forcefully housed in the cavity. At the same time, when it moves to the position of the limiting hole 412, it extends out under the drive of the elastic member to fit tightly with the annular curved surface.

[0058] Please see Figure 6 In one possible implementation, a connecting assembly is provided between the seat and the base plate 300. The connecting assembly includes a lifting base 700 and a lifting fixing plate 800. The lifting base 700 is used to connect to the base plate 300. The lifting fixing plate 800 is rotatably connected to the lifting base 700 and can be lifted relative to the base plate 300. The fixing seat 400 is connected to the lifting fixing plate 800. The connecting assembly also includes a leveling assembly, which includes a connecting hole 810 and an adjusting member 900. The connecting hole 810 is disposed in the lifting fixing plate 800. The adjusting member 900 passes through the connecting hole 810 and is threadedly connected to the connecting hole 810. One end of the adjusting member 900 facing the lifting base 700 has an abutment, which is used to abut against the lifting base 700 to adjust the angle between the lifting fixing plate 800 and the base plate 300, so that when the limiting member 530 is engaged with the limiting hole 412, the first side 130 of the zipper placement plate 100 is parallel to the base plate 300. By rotating the adjusting component 900, the lifting fixing plate 800 can be rotated relative to the lifting base 700 to adjust the angle between the lifting fixing plate 800 and the horizontal plane, thereby adjusting the angle between the zipper placement plate 100 in the working state and the horizontal plane until the zipper placement plate 100 is parallel to the base plate 300.

[0059] Based on the above, this application also provides an automatic placket opening machine, including a base plate 300 and any of the zipper placement devices. The fixing seat 400 is connected to the base plate 300 through a connecting component, which can ensure that the zipper placement plate 100 is parallel to the base plate 300 when in operation. The remaining structure of the automatic placket opening machine can refer to the prior art, and will not be described in detail here.

[0060] 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.

[0061] 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.

[0062] 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.
