Description

Technical Field

[0001] The present invention relates to the technical field of hat manufacturing devices, and in particular to a clamping and fitting device for hat production. Background Art

[0002] The production of hats is an assembly line operation, which requires the cut parts to be sewn in sequence according to the process flow, including the splicing of the hat body, the installation of the lining, the sewing of the brim, the installation of the sweatband, etc. Among them, some special processes are also included, such as the production of embroidery, printing and hot diamond decoration on the hat body. After a series of sewing processes, the hat needs to be ironed with high-temperature steam to ensure the stability of the shape of the hat body and the smoothness of the appearance.

[0003] During the ironing process, a shaping device is needed to fill the inside of the hat so that the hat is fully propped up and a more three-dimensional shape is created. Existing shaping devices are mostly inner molds inside the hat that cooperate with double-point clamps on the outside to achieve the fit between the inner surface of the hat and the inner mold. However, due to the small number of contact points between the clamps and the inner mold, the hat and the inner mold often do not fit well, resulting in wrinkles on the hat after ironing. Summary of the invention

[0004] The purpose of the present invention is to provide a clamping and fitting device for hat production, which is based on a fixed rotating seat that can be raised and lowered. Through the transmission connection formed by the fixed rotation and the side clamping assembly and the top clamping assembly, a three-dimensional clamping operation on the hat can be formed. Through the mechanical transmission formed with the negative pressure adsorption assembly, not only a safe and reliable negative pressure supply can be formed, but also the flatness of the fit between the inner surface of the hat and the inner mold seat can be improved, thereby improving the quality of ironing in many aspects.

[0005] The object of the present invention is achieved through such a technical solution, a clamping and fitting device for hat production, comprising a base frame member, an inner mold assembly, a negative pressure adsorption assembly, a side clamp assembly and a top clamp assembly, the inner mold assembly comprises an inner mold seat, the negative pressure adsorption assembly comprises an inner insert and a side pipe, the side clamp assembly comprises a side clamp seat, and the top clamp assembly comprises a transmission gear, a top rotary arm and a transmission pinion;

[0006] A lifting fixed rotating seat is provided at the middle of the top of the bottom frame member, the inner mold seat is screwed on the top of the fixed rotating seat, a conversion cylinder is fixed inside the bottom frame member, the inner insert is fixedly connected to the inner bottom end of the fixed rotating seat, the inner insert is sealed and slidably inserted in the conversion cylinder, the lateral pipe is connected to one side of the conversion cylinder, and a side hole is opened on one side of the inner insert;

[0007] The top of the bottom frame member is symmetrically rotated with a flip clamp arm on both sides, the bottom of the fixed rotating seat is transversely fixed with a bottom sliding shaft on both sides, the side clamp seat is fixedly installed on one side of the top of the flip clamp arm, and the bottom sliding shaft on the same side is slidably connected with the bottom of the flip clamp arm;

[0008] A transmission arm is screwed to one side of the upper part of the base frame member, and a transmission sliding shaft is fixed horizontally in the main body of one group of flip clamp arms. The bottom end of the transmission arm is slidably connected to the transmission sliding shaft, and the large transmission gear is fixedly connected to the top rotating shaft of the transmission arm. The top rotary arm is also screwed to one side of the upper part of the base frame member, and the small transmission gear is fixedly connected to the rotating shaft of the top rotary arm, and the large transmission gear is meshed with the small transmission gear, and the other end of the top rotary arm is fixedly installed with a top clamp seat.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] The inner mold base is used to fit with the inner surface of the hat to form support for the shape of the hat;

[0011] When the inner mold seat rises upward, it can synchronously drive the bottom sliding shaft to move upward, so that the bottom sliding shaft forms a sliding connection with the bottom end of the flip clamp arm, thereby pushing the flip clamp arm to form a rotational action, driving the side clamp seat to synchronously separate from the inner mold seat; conversely, when the inner mold seat descends, it can drive the side clamp seat to form a movement of fitting to the outside of the inner mold seat; and when the inner mold seat moves downward into place, the side clamp seat just fits into place with the outside of the inner mold seat, thereby forming a convenient clamping effect on the hat and the inner mold seat;

[0012] In addition, the lifting and lowering action of the fixed rotating seat can also synchronously drive the inner insert to move, so that only after the inner mold seat moves downward into position, the side hole can be in a position connected with the lateral pipe. In other words, only after the cap and the inner mold seat are clamped in place and the inner mold seat moves downward into position, the negative pressure connected with the lateral pipe can be connected with the inner cavity of the inner mold seat.

[0013] And synchronously, when the flipping clamp arm flips, the sliding connection formed by the bottom end of the transmission arm and the transmission sliding shaft can also drive the transmission arm to form a rotational movement, forming a coordinated transmission of the transmission large gear and the transmission small gear, so that the top rotation arm and the top clamp seat rotate, and after the side clamp seat and the outer side of the inner mold seat are in place, the negative pressure adsorption component of the bottom frame component of the side clamp assembly is synchronously fitted into place with the outer side of the inner mold seat.

[0014] By adopting the above technical solution, the present invention can form the following beneficial effects:

[0015] (1) The present invention is based on a liftable fixed rotating seat, and the inner mold seat is arranged to be rotatably connected to the fixed rotating seat, so as to facilitate the rotation adjustment of the direction of the hat clamped on the outside of the inner mold seat during operation, thereby improving the convenience of ironing operation;

[0016] (2) The present invention is provided with a transmission connection between a side clamp assembly and a top clamp assembly, so that the side clamp seats and the top clamp seat symmetrically distributed on both sides of the inner mold seat can jointly form a three-point clamping action for the hat, which can improve the stability of the hat fitting with the inner mold seat after the hat is clamped; and the side clamp assembly and the top clamp assembly are kept in coordination with the lifting action of the fixed rotating seat, so that after the inner mold seat is lifted into place, the side clamp seat and the top clamp seat are released into place, and after the inner mold seat is lowered into place, the side clamp seat and the top clamp seat are fitted with the outer surface of the inner mold seat;

[0017] (3) The present invention is also provided with a negative pressure adsorption component, which can not only provide negative pressure for the inner cavity of the inner mold base, but also utilize the through holes opened in the main body of the inner mold base to achieve the purpose of adsorbing the cap and making the cap better fit with the outer surface of the inner mold base. In addition, by utilizing the fixation of the inner insert tube and the fixed rotating seat and the sliding connection formed by the inner insert tube and the conversion cylinder, it can also achieve the action that the side hole can be connected with the side pipe only after the inner mold base and the fixed rotating seat are moved down into place and the side clamp seat and the top clamp seat are fitted into place with the outer surface of the inner mold base, thereby providing negative pressure to the inner cavity of the inner mold base more safely and reliably.

[0032] The top of the bottom frame member 1 is symmetrically screwed with a flip clamp arm 403, and the bottom sliding shaft 406 is transversely fixed on both sides of the bottom of the fixed rotating seat 201. The side clamp seat 408 is fixedly installed on one side of the top of the flip clamp arm 403. The bottom sliding shaft 406 on the same side is slidably connected with the bottom end of the flip clamp arm 403. After the fixed rotating seat 201 drives the inner mold seat 204 to fall into place, it can synchronously drive the side clamp seat 408 to form a clamping action, and the side hole 307 is just connected with the side pipe 305.

[0033] A transmission arm 503 is screwed to the upper side of the base frame component 1, and a transmission slide shaft 507 is horizontally fixed in the main body of one group of flip clamping arms 403. The bottom end of the transmission arm 503 is slidably connected to the transmission slide shaft 507, and the large transmission gear 508 is fixedly connected to the top rotating shaft of the transmission arm 503. The top rotating arm 510 is also screwed to the upper side of the base frame component 1, and the small transmission gear 512 is fixedly connected to the rotating shaft of the top rotating arm 510, and the large transmission gear 508 is meshed with the small transmission gear 512. The other end of the top rotating arm 510 is fixedly installed with a top clamping seat 513, which can drive the top clamping seat 513 to synchronously form a clamping and releasing action with the side clamping seat 408.

[0034] Here’s how it works:

[0035] The inner mold base 204 is used to fit with the inner surface of the hat to form a support for the shape of the hat, so as to facilitate high-temperature ironing of the hat;

[0036] The inner mold base 204 can be driven to form a lifting action through the fixed rotating seat 201. When the inner mold base 204 rises upward, the bottom sliding shaft 406 can be synchronously driven to move upward, so that the bottom sliding shaft 406 forms a sliding connection with the bottom end of the flip clamp arm 403, thereby pushing the flip clamp arm 403 to form a rotation action, driving the side clamp seat 408 to synchronously separate from the inner mold base 204; conversely, when the inner mold base 204 descends, the side clamp seat 408 can be driven to form a movement of fitting to the outside of the inner mold base 204; and when the inner mold base 204 moves downward into place, the side clamp seat 408 just fits into place with the outside of the inner mold base 204, thereby forming a convenient clamping effect on the hat and the inner mold base 204;

[0037] In addition, the lifting and lowering action of the fixed rotating seat 201 can also synchronously drive the inner insert tube 304 to move, so that only after the inner mold seat 204 moves downward into position, the side hole 307 can be in a position connected with the lateral pipe 305. In other words, only after the hat and the inner mold seat 204 are clamped in place and the inner mold seat 204 moves downward into position, the negative pressure connected with the lateral pipe 305 can be connected with the inner cavity of the inner mold seat 204. The purpose is not only to better achieve the fit between the inner surface of the hat and the outer surface of the inner mold seat 204, but also to prevent the negative pressure in the inner cavity of the inner mold seat 204 from being formed during the clamping process of the hat, and will not interfere with the clamping and separation work of the hat and the inner mold seat 204.

[0038] And synchronously, when the flip clamp arm 403 flips, the transmission arm 503 can also be driven to rotate through the sliding connection formed by the bottom end of the transmission arm 503 and the transmission slide shaft 507, forming a coordinated transmission of the transmission gear 508 and the transmission pinion 512, so that the top rotation arm 510 and the top clamp seat 513 rotate, and after the side clamp seat 408 is fitted into place with the outside of the inner mold seat 204, the side clamp assembly 4 bottom frame component 1 negative pressure adsorption assembly 3 is synchronously fitted into place with the outside of the inner mold seat 204, and because the inner mold seat 204 moves up and down, in order to achieve the coordination of the top clamp seat 513 and the inner mold seat 204, that is, in the process of the inner mold seat 204 moving upward, the top clamp seat 513 cannot interfere, and the moving speed of the top clamp seat 513 must be greater than the moving speed of the inner mold seat 204, which can be achieved through the different transmission ratios formed between the transmission gear 508 and the transmission pinion 512.

[0039] The specific structure of the chassis member 1 is as follows Figure 2 As shown, the bottom frame body 101 is a frame-shaped structure, the top plate 102 is fixedly connected to the top of the bottom frame body 101, and the telescopic hole 103 is opened in the middle of the main body of the top plate 102 for realizing the passage of the inner mold base 204;

[0043] The adsorption micropores 205 are evenly arranged in the main body of the inner mold base 204 to realize the passage of negative pressure, so that the inner surface of the hat is more closely adsorbed to the outer surface of the inner mold base 204 during the ironing process;

[0049] In addition, a moisture-proof mechanism is provided in the negative pressure fan 302, so that the water vapor generated during high-temperature ironing will not damage the negative pressure fan 302 and its related components.

[0050] The specific structure of the side clamp assembly 4 and the top clamp assembly 5 is as follows: Figure 6 , Figure 7 and Figure 8 As shown, the rotation slots 401 are symmetrically opened in the main body of the top plate 102, and rotation seats 402 are provided on both sides of each group of rotation slots 401.

A bottom sliding groove 407 is opened on one side of the bottom end of each set of flip clamping arms 403, and the bottom sliding shaft 406 on the same side is slidably connected in the bottom sliding groove 407;

[0052] When the fixed rotating seat 201 moves up and down, the bottom sliding shaft 406 and the bottom sliding groove 407 are driven to form a sliding fit, so that the flip clamp arm 403 rotates with the flip shaft 404 as a reference;

[0053] The top support frame 501 is fixedly connected to the middle of the top of the top plate 102, the transmission rotary seat 502 is fixedly connected to the inner side surface of the top support frame 501, the top of the transmission arm 503 is plugged with a transmission shaft 504, the transmission shaft 504 is rotatably connected to the transmission rotary seat 502, and the transmission gear 508 is plugged and fixed to one end of the transmission shaft 504;
