DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 10 As shown, an embodiment of the present invention provides a fabric loading and unloading device for a clothing printing device, comprising: a loading and unloading device body 2 mounted on a 3D printer body 1, the loading and unloading device body 2 comprising a driving component 3 for driving the fabric to move along a feeding direction, and a clamping component 4 for clamping the fabric, the clamping component 4 being located on the inner side of the driving component 3;

[0034] refer to Figure 1 The 3D printer body 1 is an existing technology, which includes a printing platform, a transmission system, a fuselage, a control system, and an ink cartridge. You can refer to the Ender-3 S1 clothing 3D printer of CREAL I TY. Its specific components are not repeated here. The loading and unloading device body 2 utilizes the space of the existing 3D printer body 1, which can not only load and unload fabrics, but also does not affect the 3D printing operation of the 3D printer body 1. It has a large space utilization rate and a compact structure.

[0035] The driving assembly 3 includes a support member 302, to which a shielding plate frame 301 is fixedly connected, and a driving member 303 is provided at the lower part of the shielding plate frame 301. The driving member 303 includes a driving motor 3031 fixedly mounted on the shielding plate frame 301, and at least two driving wheels 601 rotatably mounted on the shielding plate frame 301. The driving motor 3031 drives the driving wheel 601 to rotate through the transmission assembly 3032, and a driven wheel member 5 is provided above the driving wheel 601.

[0036] refer to Figure 3 , Figure 4 During the driving operation, the driving motor 3031 is powered on and can drive multiple driving wheels 601 to rotate synchronously through the transmission component 3032. The friction force of the driving wheel 601 on the fabric is used to realize the transportation of the fabric, which facilitates the loading and unloading of the fabric. Among them, the driven wheel 5 can apply a certain downward pressure on the fabric, increase the friction between the driving wheel 601 and the fabric, and improve the stability and accuracy of the transportation.

[0037] The support member 302 includes an L-shaped frame 3023, one end of the L-shaped frame 3023 is fixedly connected to a fixing plate 3025, the other end of the L-shaped frame 3023 is fixedly connected to a connecting block 3024, the lower part of the L-shaped frame 3023 is detachably connected to a mounting frame 3022, the lower part of the mounting frame 3022 is fixedly installed with a moving wheel 3021, the moving wheel 3021 is in contact with the body base of the 3D printer body 1, and the connecting block 3024 is fixedly connected to the shielding plate frame 301;

[0038] refer to Figure 3 , Figure 5 The fixing plate 3025 is mounted on the printing platform of the 3D printer body 1 by means of fasteners, such as screws. The moving wheel 3021 and the mounting frame 3022 provide auxiliary support for the L-shaped frame 3023 to ensure the stability of the L-shaped frame 3023. In this embodiment, the mounting frame 3022 is connected to the L-shaped frame 3023 by bolts and nuts. Therefore, the mounting frame 3022 can be removed from the L-shaped frame 3023 to ensure the stability of the shielding plate frame 301.

[0039] The transmission assembly 3032 includes the same number of synchronous pulleys as the driving pulley 601, and a synchronous belt is arranged between the multiple synchronous pulleys. The output end of the driving motor 3031 drives one of the synchronous pulleys to rotate;

[0040] refer to Figure 3 , Figure 4 During transmission operation, the output end of the driving motor 3031 drives one of the synchronous pulleys to rotate, and one of the synchronous pulleys drives the other synchronous pulleys to rotate, thereby realizing synchronous driving of multiple driving wheels 601 to rotate, ensuring the stability of the conveyed fabric, wherein the synchronous pulleys and synchronous belts are both prior arts, and both the synchronous pulleys and the synchronous belts have mutually meshing teeth for synchronous driving to avoid slipping.

[0041] The driven wheel member 5 includes a slide groove 504 provided on the shielding plate frame 301, a slider 502 is slidably connected in the slide groove 504, a clamping spring 503 is fixedly connected between the slider 502 and the top wall of the slide groove 504, a rotatable driven wheel 501 is provided on the slider 502, anti-slip grooves 602 are provided on the circumferential surfaces of the driven wheel 501 and the driving wheel 601, and a guide cone block 603 is fixedly connected to the ends of the driven wheel 501 and the driving wheel 601 away from the shielding plate frame 301;

[0042] refer to Figure 7 , Figure 3 The driven wheel 501 can rotate by itself, so it will not hinder the movement of the fabric. Since the fabric has a certain thickness, the fabric will push the driven wheel 501 to move upward, and the driven wheel 501 drives the slider 502 to move upward in the slide groove 504. The slider 502 squeezes the clamping spring 503, and the reaction force of the clamping spring 503 acts on the slider 502. Therefore, it can provide downward pressure on the fabric, thereby increasing the friction between the driving wheel 601 and the fabric, ensuring the stability and accuracy of fabric transportation.

[0043] The clamping assembly 4 includes a clamping frame 401, which is adapted to the printing platform of the 3D printer body 1. The telescopic end of the clamping cylinder 405 is fixedly connected to the top wall of the shielding plate frame 301. The lower part of the clamping frame 401 is fixedly connected to a protruding frame 402, on which the clamping cylinder 405 is fixedly installed. The protruding frame 402 is connected to a tensioning pipe frame 403 through a buffer. The tensioning pipe frame 403 is fixedly connected to an elastic sleeve 406 on one side close to the shielding plate frame 301. The elastic sleeve 406 is made of rubber material. The elastic sleeve 406 is provided with through holes, which correspond to the spare holes 4061 one by one. The front of the tensioning tube frame 403 is evenly provided with air outlet holes 4031, and the side of the tensioning tube frame 403 is evenly provided with spare holes 4061 inclined upward and inward. The inner side of the clamping frame 401 is provided with a wind-gathering arc groove 4062. The airflow blown out from the spare holes 4061 of the tensioning tube frame 403 under the elastic force of the fabric can enter the wind-gathering arc groove 4062. One side of the tensioning tube frame 403 is fixedly connected with an air pipe 404, and the air pipe 404 is connected to an external air source.

[0044] refer to Figure 2 , Figure 8 , Fig.10When clamping and fixing the fabric, the telescopic end of the clamping cylinder 405 extends out under the action of the external air source. Since the telescopic end is fixedly connected to the baffle frame 301, the cylinder body of the clamping cylinder 405 moves downward, thereby synchronously driving the protruding frame 402 and the clamping frame 401 to move downward synchronously. Since the protruding frame 402 is located at the lower part of the clamping frame 401, the protruding frame 402 first contacts the fabric, the fabric is pressed down and tightened, and then the clamping frame 401 clamps the fabric, which can ensure that the fabric is clamped in a tensioned state; secondly, during the process of feeding the fabric, the external air source enters the tensioning pipe frame 403 from the air pipe 404, and then blows out from the air outlet 4031, which can blow away the floating hair on the surface of the fabric to improve the quality of the 3D printing operation, wherein the elastic sleeve 406 can both increase the friction between the elastic sleeve and the fabric Friction can prevent the fabric from sliding, and can also play a certain buffering role to prevent the fabric from being crushed; when the tensioning tube frame 403 is subjected to the tensioning force of the fabric and moves upward for a distance, at this time, the airflow blown out from the spare hole 4061 can enter the wind-gathering arc groove 4062, so that the airflow is guided from obliquely upward to the horizontal direction, so that the airflow is blown in horizontally along the printing platform, and the airflow is blown along the fabric to the part where the 3D printing nozzle and the fabric are in contact, which plays the function of quickly cooling the 3D printing material, preventing the 3D printing material from adhering to the printing platform, and improving the quality of 3D printing. In order to increase the amount of airflow, grooves can be evenly opened on the side surface of the clamping frame 401 that contacts the fabric for airflow to pass through. The longitudinal section of the hurricane arc groove 4062 is in the shape of a circular arc, and its length is greater than the length of the spare hole 4061 to prevent airflow leakage.

[0045] The buffer member includes a slide bar 702 fixedly mounted on the tensioning pipe frame 403, the slide bar 702 passes through the protruding frame 402, a buffer spring 701 is sleeved on the slide bar 702, the buffer spring 701 is located between the protruding frame 402 and the tensioning pipe frame 403, and the upper end of the slide bar 702 is fixedly connected to the end block 703;

[0046] refer to Fig. 9 During the buffering operation, if the fabric is pressed down to the stretching limit, the protruding frame 402 continues to move downward, which will squeeze the buffer spring 701. The buffer spring 701 is compressed and will not directly act on the tensioning tube frame 403, thereby preventing the fabric from being torn by the tensioning force, thereby playing a role in ensuring the fabric.

[0047] Working principle: During fabric loading and unloading, the fabric is put in from the front side, so that the fabric passes through the gap between the driving wheel 601 and the driven wheel 501. The guide cone block 603 can guide the fabric into it, reducing the difficulty of operation. The driving motor 3031 is powered on, and the output end of the driving motor 3031 drives one of the synchronous belt wheels to rotate, and one of the synchronous belt wheels drives the other synchronous belt wheels to rotate, thereby realizing synchronous driving of multiple driving wheels 601 to rotate, ensuring the stability of the conveyed fabric, and using the friction of the driving wheel 601 on the fabric to realize the conveying of the fabric. , which is convenient for loading and unloading of fabrics. During the process of feeding fabrics, the external air source enters the tensioning tube rack 403 from the air pipe 404, and then blows out from the air outlet 4031, which can blow away the floating hair on the surface of the fabric to improve the quality of 3D printing operations. When the tensioning tube rack 403 is subjected to the tensioning force of the fabric and moves upward for a distance, the airflow blown out from the spare hole 4061 can enter the wind arc groove 4062, so that the airflow is guided from obliquely upward to horizontally, so that the airflow is blown in horizontally along the printing platform, which plays a role in rapidly cooling the 3D printing material. Avoid 3D printing materials from adhering to the printing platform and improve the quality of 3D printing. The driven wheel 5 can apply a certain downward pressure on the fabric, increase the friction between the driving wheel 601 and the fabric, and improve the stability and accuracy of transportation. After the fabric is transported to the rear side, the transportation is stopped. Under the action of the external air source, the telescopic end of the clamping cylinder 405 extends out. Since the telescopic end is fixedly connected to the baffle frame 301, the cylinder body of the clamping cylinder 405 moves downward, thereby synchronously driving the protruding frame 402 and the clamping frame 401 to move downward synchronously. The frame 402 is located at the lower part of the clamping frame 401. Therefore, the protruding frame 402 first contacts the fabric, the fabric is pressed down and tightened, and then the clamping frame 401 clamps the fabric to ensure that the fabric is clamped in a tensioned state. If the fabric is pressed down to the limit of stretching, the protruding frame 402 continues to move downward, it will squeeze the buffer spring 701. The buffer spring 701 is compressed and will not directly act on the tensioning tube rack 403, avoiding the fabric from being torn by the tensioning force, thereby playing a role in ensuring the fabric. After loading and unloading, the 3D printer body 1 then performs printing operations.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
