Description

Technical Field

[0001] The invention belongs to the pressing equipment for materials, and relates to a process and a machine that can form a recess at the position corresponding to the chest of an elastic vest and attach a breast cup to the recess. More specifically, it relates to a process for attaching a breast cup to a female elastic vest, its hot press, and a female elastic vest. Background Art

[0002] Female elastic vests are usually sewn with breast cups, which can also function as bras, enabling a vest to have two functions and eliminating the need to wear a bra when in use.

[0003] Traditionally, the production of an elastic vest with a breast cup requires flattening the elastic fabric, hot-pressing a recess at the position corresponding to the breast, then sewing the breast cup around the recess, rolling up the elastic fabric, and bonding or sewing the two sides. The elastic vests made by this process have the following defects: First, the process is cumbersome and the production cycle is long; second, both bonding and sewing on the two sides will leave marks, which are neither beautiful nor comfortable.

[0004] Generally, if there is no sewing at the two sides, it is called seamless in the industry; if the two sides are connected by bonding, it is called traceless in the industry. Currently, for the production of elastic vests, people more often adopt the traceless process, that is, the four sides of the material are woven into a tubular shape, and there is neither bonding nor sewing on the two sides, and there are no bonding or sewing marks. The traceless elastic vest made of this shaped material has the characteristics of beautiful appearance and comfortable wearing, and is deeply loved by consumers.

[0005] However, for how to attach a breast cup to a traceless elastic vest to suit female wear, it has troubled manufacturers, and the process or equipment produced by machines has not been solved, and the automated production of a traceless elastic vest with a breast cup cannot be achieved.

[0006] There is no ready-made technology for forming a recess at the position corresponding to the chest on the elastic vest material rolled into a tubular shape. Moreover, for the elastic material of the rolled tubular vest, even if a recess can be formed on it, during the forming process, due to the restraint of other parts of the tubular shape on both sides of the recess, the recess is prone to deviation during the hot-press shrinkage in the mold cavity, resulting in misalignment when it is subsequently bonded to the breast cup. Summary of the Invention

[0007] The present invention provides a process for attaching a breast cup to an elastic vest, its hot press, and a vest, which can form a recess on the elastic material of the elastic vest rolled into a tubular shape, prevent the material from being loose due to the shape making it difficult to fix, ensure the accurate position of the formed recess, and can paste the breast cup at the recess, especially suitable for the processing of traceless elastic vests.

[0008] The process for attaching breast cups to a stretch vest proposed by the present invention, as well as its hot press and vest, can also prevent the recess from deviating due to shrinkage during the formation of the mold cavity, overcoming the further influence of shrinkage on the position of the recess in the mold cavity, and preventing misalignment when attaching the breast cups subsequently.

[0009] The process for attaching breast cups to a stretch vest of the invention is realized by the following solution:

[0010] A process for attaching breast cups to a stretch vest is characterized in that

[0011] (10) Turn the elastic material of the stretch vest inside out to form a turned - inside - out elastic material;

[0012] (20) Let the turned - inside - out elastic material be sleeved in the lower template set in a hanging manner;

[0013] (30) Use two movable struts located below the lower template to move downward and tension the turned - inside - out elastic material;

[0014] (40) Prop up and press against the free end of the lower template by a movable support rod located below the lower template;

[0015] (50) Move the upper template downward, and form a recess at the corresponding position of the chest on the turned - inside - out elastic material by the male mold of the upper template and the female mold of the lower template;

[0016] (60) Let the upper template move upward away from the lower template to separate the male and female molds;

[0017] (80) Place the breast cup in the recess;

[0018] (90) Use a pressing frame located above the lower template to move downward and press the breast cup around the recess of the turned - inside - out elastic material.

[0019] Preferably, in the above process, after step (90), the following steps are also performed:

[0020] (100) Let the pressing frame move upward to reset and leave the lower template;

[0021] (110) Move the two movable struts located below the lower template upward and reset;

[0022] (120) Let the movable support rod disengage from the lower template and take out the turned - inside - out elastic material from the lower template.

[0023] After performing steps (100)-(120), the turned - inside - out elastic material can be easily taken out from the lower template.

[0024] More preferably, considering the different elasticities of the elastic material, in the above process, between step (60) and step (80), the following step (70) is also included:

[0025] (70) Move the two support rods located below the lower template upward by an appropriate distance to make the two sides of the flipped elastic material relatively loose, so that the concave part can shrink evenly.

[0026] Performing step (70) can better solve the problem of different shrinkages of elastic materials with different elasticities during the hot pressing formation of the concave part.

[0027] Preferably, in the above process, the two movable support rods move upward or downward simultaneously, and are driven by a motor through a gear transmission mechanism and two lead screws, so that they move up and down along the two guiding rods respectively.

[0028] Thus, the moving distance of the two movable support rods depends on the rotation of the motor, and the appropriate moving distance of the two support rods can be achieved by the rotation of the motor.

[0029] More preferably, in the above process, the elastic vest is a traceless elastic vest.

[0030] Thus, the traceless elastic vest with attached breast cups can be processed by the inventive process.

[0031] The flipped elastic material obtained thereby can be flipped over again to obtain a female elastic vest with attached breast cups.

[0032] The inventive vest is realized by the following solution:

[0033] A vest, characterized in that it adopts a traceless elastic vest and attaches breast cups by the above process.

[0034] The inventive hot press is realized by the following solution:

[0035] A hot press, in which an upper die device and a lower die device are installed in the machine shell, and the upper template of the upper die device can move up and down under the action of a hot pressing cylinder and press against the lower template of the lower die device; wherein, a male die is installed on the upper template and a female die is installed on the lower template; the characteristics are: the lower die device further includes side plates and a bottom plate, the side plates are installed on the bottom plate, and the lower template is fixedly suspended on the side plates; two movable support rods are installed on the side plates below the lower template, and the two movable support rods can move upward or downward; a movable support rod is also installed on the bottom plate below the lower template, and the movable support rod can support below the free end of the lower template or disengage from the lower template, and the upper die device is also installed with a pressing frame, and the pressing frame can move upward or downward and press against the lower template.

[0036] Preferably, in the above hot press, the upward or downward movement of the two movable support rods is driven by a motor through a gear transmission mechanism and two transmission lead screws to move upward or downward along the two guiding rods simultaneously.

[0037] Therefore, the distance that the movable support rod moves upward or downward along the guide rod depends on the rotation of the motor. By controlling the rotation of the motor, the support rod can be controlled to move an appropriate distance to adapt to the contraction of different elastic materials.

[0038] In this way, the elastic vest can be put into the lower template, and then the motor can drive the two movable struts to move downward simultaneously along the two guide rods through the gear transmission mechanism and the two screws, and the elastic vest is appropriately tensioned by the two movable struts, and the free end of the lower template is supported by the movable support rod. The male mold and the female mold can form a recess at the position of the elastic vest corresponding to the chest through hot pressing. Then, the male mold moves upward with the upper template and leaves the lower template, and the two struts can move upward by an appropriate distance to relax the elastic vest so that the elastic material, especially the recess, shrinks evenly in the mold cavity. Finally, a breast cup can be placed in the recess, and the breast cup and the recess are pressed together around the pressing frame and the lower template.

[0039] The elastic vest attaching bra cup process and the ironing machine created by the present invention are suitable for the production of women's seamless elastic vests. A recess can be formed on the elastic material of the rolled-up cylindrical vest, and the bra cup is attached to the recess, which solves the problem that women's seamless elastic vests have not been able to be produced by machines, and is beneficial to reducing the labor intensity of workers and improving the efficiency of production.

[0040] According to the elastic vest attaching breast cup process and the ironing machine thereof, the elastic vest can be easily put into the lower template, and then, it is stretched open by two support rods to make the elastic vest appropriately tensioned, and the movable support rod is supported on the free end of the lower template, which is conducive to the male and female molds to form recesses on the elastic material, and can ensure the accuracy of the position of the recess, and can prevent the problem of defective products caused by deviation in the position of the recess.

[0041] In the elastic vest attached chest cup process and the ironing machine thereof, after the male mold and the female mold form a concave portion at the position of the elastic vest corresponding to the chest, the two support rods can be appropriately loosened so that the two sides of the elastic vest are no longer acted upon by force, so that the concave portion can shrink evenly in the mold cavity, avoiding the influence of tension on the shrinkage of the elastic material, and preventing the concave portion from being easily deformed in the mold cavity.

[0042] The vest of the present invention has the characteristics of having a breast cup and showing no trace, which can make women more acceptable and fond of it.

[0043] Although the manufacturing process and the ironing machine of the invention are proposed based on the process of attaching a stretch vest to a chest cup, it is also suitable for the processing of attaching other auxiliary materials to seamless tubular fabrics or seamless annular clothing underwear.
