Description

Technical Field

[0001] The invention belongs to the technical field of clothing processing equipment, and in particular relates to a wire-free bra processing equipment. Background Art

[0002] A wire-free bra refers to a type of underwear that does not have a built-in underwire. Although a wire-free bra can shape the wearer's breasts, the pressure on the breasts over time will cause skin redness and swelling, and increase the probability of breast diseases. Therefore, wire-free bras have become one of the main choices for users.

[0003] Among them, underwire-free bras mainly rely on the cup to support the user's chest. During the production process, foaming or hot pressing equipment is mostly used to make the cup. The prefabricated mold of such cup needs to be cut to meet the subsequent fabric bonding or other processing. At present, a common processing method mostly adopts stamping cutting, that is, the cutting mold is used to align the edge position of the cup on the prefabricated mold, and then the cutting mold is pressed by the stamping equipment to use pressure for cutting. However, after the cutting is completed, since the cup still exists in the cutting mold, the staff is required to deduct the cup. After it is completely taken out, the cutting mold is removed and the residual material is removed, and then the next processing is carried out. On the one hand, this method is inefficient. On the other hand, manually deducting the cup from the cutting mold is prone to damage the cup surface due to the operator's nails, tools and other sharp parts, thereby reducing the product yield.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1: Figure 1-6 As shown, a wire-free bra processing device comprises a machine base 1 and a punching machine, wherein the punching machine is rotatably arranged at the rear side of the machine base 1, a cutting table 12 is arranged at the upper end of the machine base 1 and is equipped with a punching knife 11 matching the bra cup, and the machine base 1 is provided with a stripping mechanism matching the cutting table 12;

[0027] The stripping mechanism includes a lifting assembly, a power assembly and a matching assembly. The lifting assembly is embedded in the machine base 1 and matches the position of the cutting table 12. The matching assembly is arranged at the rear side of the machine base 1 and matches the position of the punching machine. The power assembly is embedded in the machine base 1 and connects the lifting assembly and the matching assembly.

[0028] The mating components include a rocker 2, a slide 21 and a driver. An active cavity 22 is opened at the rear end of the machine base 1. The rocker 2 is elastically rotatable in the active cavity 22 and one end extends out of the active cavity 22. The slide 21 is slidably arranged in the active cavity 22 and abuts and matches with the other end of the rocker 2. The other end of the slide 21 is connected and matched with the power component. The slide 21 is an overall right-angled trapezoidal structure and the hypotenuse abuts with the rocker 2. The driver is arranged in the punching machine and corresponds to the position of the rocker 2. The rocker 2 flips to the side of the cutting table 12 in the initial state.

[0029] When cutting a bra, first place the preformed mold on the cutting table 12, then place the punching knife 11 on the preformed mold and align it with the cup. After the preparation is completed, the punching machine can be controlled to press the punching knife 11, so that the punching knife 11 cuts out the cup on the preformed mold. Finally, the cup is taken out and the remaining preform is removed, and the above steps are repeated to perform continuous punching processing. When the punching machine is controlled to press the punching knife 11, the orientation of the punching machine will be adjusted and the matching components will be driven during the adjustment process. When punching is performed, that is, when the punching machine adjusts the corresponding cutting table 12, since the rocker 2 is flipped toward the side of the cutting table 12 in the initial state, the driver set on the punching machine will directly pass over the rocker 2 and will not affect the remote sensing. On the contrary, after the punching machine is pressed, the punching machine will be controlled to move away from the cutting table 12. During this process, the driver moves in the opposite direction. The rocker 2 will be pushed, and then the rocker 2 will be turned over in the active cavity 22 and act on the slide 21, wherein the slide 21 is a right-angled trapezoidal structure as a whole, and the beveled edge is in contact with the remote sensing device. Therefore, the turning of the rocker 2 will push the slide 21, thereby driving the power component on the rear side, until the lifting component is driven by the power component. In this way, when the punching machine moves away from the cutting table 12, the cup punched by the punching knife 11 on the cutting table 12 will be demoulded synchronously through the lifting component, wherein the lifting component corresponds to the blank area of ​​the punching knife 11, that is, corresponds to the center position of the cup, so that the lifting component and the punching knife 11 can be avoided from colliding, so that in the production process, the process of manually deducting the cup from the punching knife 11 can be reduced, which on the one hand improves the processing convenience, and on the other hand reduces the damage to the cup caused by clamping and rubbing during the deducting process, resulting in a decrease in the yield rate;

[0030] Furthermore, since the rocker arm 2 is elastically rotatably connected in the active cavity 22, after the driver is completely separated from the rocker arm 2, the rocker arm 2 will automatically reset, and the corresponding power assembly and lifting assembly will also reset synchronously. This process is completed during the rotation of a punching machine, that is, the lifting assembly is reset before the next precast mold is prepared for punching, which can avoid affecting the placement and positioning of subsequent precast molds and improve production continuity.

[0031] The punching machine includes a rotating column 3, a punching unit 31 and a pressure plate 32. The rotating column 3 is rotatably arranged on the rear side of the machine base 1 through a connecting ear. The punching unit 31 is connected to the upper end of the rotating column 3. The pressure plate 32 is arranged on the lower side of the punching unit 31 and connected to its output shaft. The position of the cutting table 12 at the upper end of the machine base 1 is on the motion trajectory of the pressure plate 32 with the axis of the rotating column 3 as the center.

[0032] The driver includes a push head 4, a first limit plate 41 and a first spring 42. The rotating column 3 is provided with a first step cavity 43 of the unpacking machine base 1. The opening direction of the first step cavity 43 coincides with the length direction of the punching unit 31. The first limit plate 41 is slidably arranged in the first step cavity 43. The push head 4 is connected to the first limit plate 41 and extends out of the first step cavity 43. The circular motion trajectory of the push head 4 coincides with the extended part of the rocker 2. The first spring 42 is arranged in the first step cavity 43 and is connected to the other end of the first limit plate 41.

[0033] The rotating column 3 is used to connect various components and provide a rotating support force. The punching unit 31 uses a hydraulic cylinder to provide downward pressure. Its output shaft extends to push the pressure plate 32 downward, thereby generating a downward pressure on the punching knife 11 to complete the punching of the prefabricated mold. When the position of the punching unit 31 on the base is controlled, the punching unit 31 will drive the pressure plate 32 to produce a circular motion with the rotating column 3 as the center, that is, away from or close to the cutting table 12. When approaching the cutting table 12, the jacking assembly does not need to be started. The push head 4 in the driver is in contact with the rocker 2. Since the rocker 2 cannot be turned over at this time, the push head 4 is guided by the rocker 2 to be tilted, and the push head 4 is retracted into the first step cavity 43 in cooperation with the first limit plate 41 and the first spring 42 until it completely passes over the rocker 2 and then extends again.

[0034] When the punching unit 31 is away from the cutting table 12, the cutting is completed and the cup needs to be demoulded. At this time, the rotating column 3 rotates to drive the push head 4 to push the rocker 2. At this time, the rocker 2 can flip in the opposite direction, and then drive the power component and the lifting component to demould the cup. With the continuous movement of the push head 4, the inclination direction of the rocker 2 is completely reversed. Under the secondary guidance of the resistance and the bevel of the rocker 2, the push head 4 is retracted into the first step cavity 43 again until it completely passes over the rocker 2, and the rocker 2 is reset by its own elastic rotation after being separated from the push of the push head 4. In this way, the lifting component can be reset after being lifted and demoulded, so that after the cup is ejected from the punching knife 11, it will not be blocked on the cutting table 12 to affect subsequent processing, and can improve the efficiency and convenience of unloading without affecting the subsequent loading needs. The elastic rotation can be performed by means such as a torsion spring or a clockwork spring.

[0035] The power assembly includes a connecting rod 5, a first plug body 51 and a second spring 52. The base 1 is provided with a second step cavity 53. The first plug body 51 is slidingly sealed in the second step cavity 53. The connecting rod 5 is concentrically connected to the first plug body 51 and slides into the movable cavity 22 to be connected to the slide 21. The second spring 52 is disposed in the second step cavity 53 and is connected to the other end of the first plug body 51.

[0036] The lifting assembly includes a second plug body 6, a third spring 61, a lifting rod 62, a lifting plate 63, an extension rod 64 and a top head 65. The machine base 1 is provided with a third step cavity 66 corresponding to the cutting table 12, and an upper cavity 67 that is interconnected is provided on the upper side of the third step cavity 66. The second step cavity 53 and the third step cavity 66 are connected through a conduit fluid path. The second plug body 6 is slidingly sealed in the third step cavity 66. The space between the second plug body 6, the conduit and the first plug body 51 is completely filled with hydraulic oil. The lifting rod 62 is concentrically connected to the second plug body 6 and slides into the upper cavity 67. The lifting plate 63 is slidingly arranged in the upper cavity 67 and connected to the lifting rod 62. The number of extension rods 64 and top heads 65 is two and corresponds to each other in pairs. One end of the extension rod 64 is connected to the lifting plate 63, and the top head 65 is connected to the other end of the extension rod 64 and slides upward to pass through the corresponding position of the cutting table 12 to form a replacement. The third spring 61 is sleeved on the lifting rod 62 and is located in the third step cavity 66.

[0037] When the rocker 2 flips, it pushes the slide 21, and the slide 21 simultaneously moves and slides and pushes the first plug 51 through the connecting rod 5. The first plug 51 slides in the second step cavity 53, and the internal hydraulic oil is injected into the third step cavity 66 through the conduit. The second plug 6 is pushed by the delivery of the hydraulic oil, and then the lifting rod 62, the lifting plate 63 and the extension rod 64 move upward, and finally the ejector 65 is ejected from the high cutting table 12, completing the demoulding and ejection of the cup;

[0038] When the rocker 2 loses the push of the push head 4, the first plug body 51 and the second plug body 6 will be reset and moved through the reset thrust of the second spring 52 and the third spring 61, so that the top head 65 will descend and reset, the slide 21 will reset and the reset auxiliary rocker 2 will be reset through the reset push.

[0039] The minimum compression force of the first spring is greater than the sum of the maximum compression forces of the second spring and the third spring, so as to ensure that the push head will not be passively retracted into the first step cavity when the jacking assembly is driven.

[0040] Example 2: Figure 1-2 As shown in , 5-6, it is a further improvement on the basis of Example 1, a cleaning mechanism is further provided between the cutting table 12 and the machine base 1, the cleaning mechanism includes a synchronization component and a slag pusher plate 7, the synchronization component is provided on the side of the machine base 1 and is connected to the punching knife 11 by bolts, the side of the machine base 1 away from the cutting table 12 is an inclined surface 71, the slag pusher plate 7 is slidably embedded in the inclined surface 71 and is transmission-connected to the synchronization component.

[0041] The synchronization assembly includes an L-shaped rod 72, a gear 73 and a rack 74. The L-shaped rod 72 is rotatably arranged on the side of the machine base 1 through a connecting ear. The other end of the L-shaped rod 72 is connected to the punching knife 11 through a bolt. The gear 73 is concentrically connected to the rotating part of the L-shaped rod 72. The rack 74 is slidably embedded in the machine base 1 and one end is connected to the slag pushing plate 7. The rack 74 is meshed and matched with the gear 73.

[0042] Furthermore, after the preformed mold is punched, the remaining preformed mold needs to be removed after the punching knife 11 is removed. In order to ensure the cleanliness of the processing site and prevent the residue from falling around during the casting process and affecting the processing production, the punching knife 11 is directly flipped when removing the residue. At this time, since the punching knife 11 is connected to the L-shaped rod 72, the L-shaped rod 72 will be flipped synchronously with the punching knife 11 to form a connecting support. Further, in order to ensure the stability of the flipping, the L-shaped rod 72 is connected to the machine base 1 with a damping rotation and the maximum flip angle is 1 00°-130°, at this time, the residue on the cutting table 12 can be swept into the inclined surface 71 of the machine base 1, and fall into the waste container on the lower side through the guidance of the inclined surface 71. During the flipping process of the L-shaped rod 72, the rack 74 will be synchronously driven by the gear 73. At this time, the rack 74 will push and pull the slag pushing plate 7 according to the rotation direction of the gear 73, thereby playing a role in pushing and cleaning the residue that has not completely slid off the inclined surface 71 of the machine base 1 to avoid accumulation, which can improve the collection and guidance of the residue and improve the cleanliness of the processing site.

[0043] Furthermore, the extended portion of the L-shaped rod is made of a material with deformation elasticity to meet the downward pressure on the punching knife during punching. Of course, a retractable connecting piece such as a spring, a spring, etc. can also be provided at the right angle portion of the L-shaped rod to further meet the needs of connection and buffering.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
