Description

Technical Field

[0002] Thermal transfer refers to the process of transferring patterns, texts, trademarks, etc. to the surface of target substrates such as clothing, fabrics, ceramics, plastic parts or metal parts under high temperature and high pressure environment with the help of thermal transfer paper.

The present invention is provided with a pre-fixed structure. When the steering rod drives the bottom plate to move to the bottom of the electric heating plate through the connecting seat, the connecting flange will drive the pre-pressing cover to cover the outside of the transfer paper, and the electric push rod will continue to move downward, and the pre-pressing spring will be on the connecting seat. The bottom end of the connecting flange contracts, causing the electric heating plate to move downward, thereby causing the electric heating plate to press the transfer finger onto the top of the clothing. The electric heating plate assists in heating, causing the transfer paper to print the pattern on the outer surface of the clothing, thereby realizing the device's function of facilitating pre-fixation, thereby avoiding the transfer paper from being misplaced and wrinkled during the downward pressing process.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the specification 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.

[0022] Please see attached Figure 1 , Attachment Figure 3 , Attachment Figure 6 and attached Figure 7 The embodiment of the present invention provides a multi-station fully automatic thermal transfer production line, including a chassis 1, a calibration mechanism 2 is arranged in the middle of the chassis 1, a fixing mechanism 3 is arranged inside the calibration mechanism 2, and a hot pressing mechanism 4 is arranged at the rear of the top of the chassis 1; The calibration mechanism 2 includes a servo motor 201, the bottom end of the servo motor 201 is fixedly connected to the middle of the bottom end of the chassis 1, the output end of the servo motor 201 is fixedly connected to a turntable 202, a plurality of L-shaped plates 203 are fixedly connected to the outer side of the top of the turntable 202, a plurality of L-shaped plates 203 are fixedly connected to the middle of one side close to each other, a plurality of U-shaped frames 204 are fixedly connected to one side close to each other, a servo motor 205 is fixedly connected to the output end of the plurality of servo motors 205, and the output ends of the plurality of servo motors 205 are all connected to the U-shaped frame 204. The L-shaped frame 204 is fixedly connected to an impeller 206, and driving wheels 207 are fixedly connected to the outer sides of the multiple impellers 206. Driven wheels 208 are meshed on both sides of the multiple driving wheels 207. A rotating rod 209 is fixedly connected to the middle of one side of the multiple driven wheels 208 close to the L-shaped plate 203. The outer sides of the rotating rod 209 are rotatably connected to the two sides of the rear part of the L-shaped plate 203 respectively. The top of the turntable 202 is fixedly connected to a supporting frame 210, and the top of the supporting frame 210 is fixedly connected to a plurality of cameras 211.

[0023] The chassis 1 can provide support for the servo motor 201, and the intermittent start and stop of the servo motor 201 can drive the turntable 202 and the evenly distributed L-shaped plates 203 to intermittently rotate 90 degrees, thereby reserving time for subsequent pattern transfer and putting the clothing on the rotating rod 209 or taking it off from the outside of the rotating rod 209. When the L-shaped plate 203 and the rotating rod 209 connected thereto are driven by the turntable 202 to move to the front area of ​​the chassis 1, the workers can stretch the clothing and put it on the surfaces of the rotating rods 209 on both sides at the same time. As the turntable 202, the L-shaped plate 203 and the rotating rod 209 drive the clothing to move to one side, the camera 211 can be used to capture the actual laying situation of the clothing and upload it to the control host. When there is a deviation due to the artificial sleeve, the servo motor 205 can be controlled to start by controlling the host. At this time, the impeller 206 connected to the servo motor 205 can rotate quickly to blow air from the holes reserved on the surface of the L-shaped plate 203 to the area where the clothes are located, which can further cause the clothes to expand to a certain extent. As the clothes expand, the torsional deflection caused by the artificial sleeve can be restored by itself. At the same time, since the impeller 206 is also connected to the driving wheel 207 through the reinforcing plate, the driving wheel 207 can drive the driven wheel 208 meshing with it to rotate by using the impeller 206, and the rotating rod 209 connected to the driven wheel 208 can rotate synchronously, so as to use the friction force to drive the clothes to rotate from both sides inside the clothes until both sides of the clothes are The side seams are in the same horizontal plane as the rotating rods 209 on both sides. At this time, the control host controls the servo motor 205 to stop working to keep the current position of the clothing. When the servo motor 201 drives the turntable 202 and the L-shaped plate 203 to move again, the clothing whose position has been adjusted can be moved to the thermal transfer area at the rear of the chassis 1 for transfer. In addition, driven by the servo motor 201 and the turntable 202, the clothing that has completed the transfer can be moved to the next station again for cooling. After it is rotated to the front of the chassis 1 again, the clothing that has completed the transfer can be taken off and put on another clothing to be transferred. In summary, the impeller 206, the rotating rod 209 and related components can be used to adjust the clothing to a straight state by itself, and drive The garment is rotated to adjust the front surface or the back surface of the garment to face the heat pressing mechanism 4, so as to prevent the garment from being twisted or skewed due to the influence of personal subjective consciousness when the garment is manually laid, thereby avoiding the position difference of the transferred pattern due to the different areas of the garment facing the heat pressing mechanism 4, thereby ensuring the consistency of the garment. In addition, since the worker only needs to put the garment to be transferred on the surface of the rotating rod 209 and remove the transferred garment from the surface of the rotating rod 209, there is no need to adjust the actual laying position of the garment one by one, so the overall transfer efficiency can be greatly improved. When it is necessary to transfer the front and back sides of the garment, it is only necessary to use the rotating rod 209 to drive the transferred garment to rotate 180 degrees again to quickly transfer the back side.

[0024] Please see attached Figure 4 -Attached Figure 6The outer side of the bottom end of the turntable 202 is rotatably connected to a limiting frame 212, the bottom end of the limiting frame 212 is fixedly connected to the bottom end of the chassis 1, and the outer sides of the bottom ends of the multiple L-shaped plates 203 are slidably connected to the top of the chassis 1.

[0025] The turntable 202 can be supported by the limit frame 212 to prevent the turntable 202 from shaking when it moves and to prevent the servo motor 201 from being excessively squeezed. In addition, the chassis 1 can cooperate with the turntable 202 to guide and support the evenly distributed L-shaped plates 203 to prevent the L-shaped plates 203 from being stressed and flipped to the side away from the turntable 202 during thermal transfer.

[0026] Please see attached Figure 7 The driving wheels 207 are rotatably connected to the middle of the side close to the multiple L-shaped plates 203 on the side away from the U-shaped frame 204, and the driven wheels 208 are rotatably connected to the two ends of the side close to the multiple L-shaped plates 203 on the outside of the side away from the U-shaped frame 204.

[0027] The driving wheel 207 and the driven wheel 208 can be limited by the L-shaped plate 203 to prevent displacement during movement, thereby ensuring that the driving wheel 207 and the driven wheel 208 can always maintain effective meshing.

[0028] Please see attached Figure 4 , Attachment Figure 7 and attached Figure 8 The outer side of the multiple rotating rods 209 close to the L-shaped plate 203 is rotatably connected to a round table 213, the closer side of the multiple round tables 213 is fixedly connected to the closer side of the inner side of the L-shaped plate 203, and the middle part of the outer side of the multiple rotating rods 209 is fixedly connected to a rubber sleeve 214.

[0029] The round table 213 can increase the contact area between the rotating rod 209 and the L-shaped plate 203, thereby dispersing the force acting on the contact portion of the rotating rod 209 and the L-shaped plate 203, preventing the rotating rod 209 from being broken due to excessive force. In addition, the rubber sleeve 214 can increase the friction between the rotating rod 209 and the clothing, ensuring that the clothing can be driven to rotate when the rotating rod 209 rotates.

[0030] Please see attached Figure 1 and attached Figure 4 The multiple L-shaped plates 203 are all staggered with the support frame 210 , and the multiple cameras 211 are all facing the L-shaped plates 203 .

[0031] The L-shaped plate 203 and the support frame 210 are offset to ensure that they will not interfere with each other, and the camera 211 facing the L-shaped plate 203 can facilitate the camera 211 to capture the actual situation before and after the clothing is adjusted, thereby facilitating the control host to determine the start and stop requirements of the servo motor 205.

[0032] Please see attached Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 8 The fixing mechanism 3 includes a special-shaped ring 301, the bottom end of the special-shaped ring 301 is fixedly connected to the outer side of the bottom end of the chassis 1, and a plurality of cross plates 302 are arranged on the top of the special-shaped ring 301, the tops of the plurality of cross plates 302 all penetrate the L-shaped plate 203 and are fixedly connected with a horizontal plate 303, the front and rear ends of the plurality of horizontal plates 303 are rotatably connected with a rotating plate 304, the ends of the plurality of rotating plates 304 away from the horizontal plate 303 are rotatably connected with a vertical plate 305, the ends of the plurality of vertical plates 305 close to the horizontal plate 303 are fixedly connected with a trapezoidal block 1 306, the tops of the plurality of trapezoidal blocks 1 306 are all abutted with a trapezoidal block 2 307, the tops of the plurality of trapezoidal blocks 2 307 are all fixedly connected with an arc plate 308, and the upper parts of the plurality of arc plates 308 are all abutted against the front and rear sides of the bottom end of the rotating rod 209.

[0033] The movement direction of each horizontal plate 303 can be restricted by the cross plate 302 to ensure that the horizontal plate 303 can only move up and down. Since there is a pit in the front part of the special-shaped ring 301, when the cross plate 302 and the horizontal plate 303 move to the pit area, the cross plate 302 and the horizontal plate 303 can actively move downward under the action of gravity. At this time, the rotating plate 1 304 connected to the horizontal plate 1 303 can rotate to a certain extent and push the vertical plate 305 to drive the trapezoidal block 1 306 away from the trapezoidal block 2 307, and as As the trapezoidal block 1 306 and the trapezoidal block 2 307 separate, the trapezoidal block 2 307 that loses its support can drive the arc plate 308 to move downward and away from the rotating rod 209. At this time, the garment that has completed the transfer can be taken off the outer side of the rotating rod 209 and put into another garment to be transferred. On the contrary, when the cross plate 302 and the cross plate 1 303 move with the L-shaped plate 203 and leave the front area of ​​the chassis 1, the cross plate 302 can move upward along the pit in the front area of ​​the special-shaped ring 301 until it moves to the top surface of the special-shaped ring 301. At this time, the cross plate 30 2 can push the horizontal plate 1 303 to move up to the position flush with the rotating rod 209, thereby providing a support basis for subsequent stamping. At the same time, as the horizontal plate 1 303 moves up, the rotating plate 1 304 can rotate in the opposite direction to pull the vertical plate 305 and the trapezoidal block 1 306 close to the trapezoidal block 2 307, and then the trapezoidal block 2 307 can be driven by the inclined surface matched between the trapezoidal block 1 306 and the trapezoidal block 2 307 to drive the arc plate 308 to move up until the arc plate 308 contacts the rotating rod 209 through the clothing. The lines on the surface of the arc plate 308 that are perpendicular to the direction of the rotating rod 209 can compress the clothes to a certain extent, preventing the clothes from sliding directly off the surface of the rotating rod 209 due to the airflow generated by the impeller 206. At the same time, the arc plate 308 can also support the rotating rod 209 to prevent the rotating rod 209 from swinging due to its long length when rotating. In addition, since the arc plate 308 and the rotating rod 209 are relatively smooth, when the clothes are acted upon by the rubber sleeve 214, they can still make horizontal relative rotation along the surfaces of the arc plate 308 and the rotating rod 209.

[0034] Please see attached Figure 8 The bottom ends of the multiple trapezoidal blocks 306 are slidably connected to the bottom end of the L-shaped plate 203, the two sides of the multiple trapezoidal blocks 307 are fixedly connected to the guide plates 309, the guide plates 309 are penetrated by guide rods 310, and the bottom ends of the multiple guide rods 310 are fixedly connected to the bottom end of the L-shaped plate 203.

[0035] The L-shaped plate 203 can be used to guide the trapezoidal block 1 306 and the vertical plate 305, and the guide plate 309 and the guide rod 310 can ensure that the trapezoidal block 2 307 can only move in the vertical direction. In summary, it can be ensured that the trapezoidal block 1 306 can effectively contact the trapezoidal block 2 307, and then ensure that the arc plate 308 can cooperate with the rotating rod 209 to jointly limit the movement direction of the clothing to a certain extent.

[0036] Please see attached Figure 4 and attached Figure 5 The bottoms of the multiple cross plates 302 are rotatably connected to rollers 311 , and the bottoms of the multiple rollers 311 are slidably connected to the top of the special-shaped ring 301 .

[0037] The roller 311 can reduce the friction between the cross plate 302 and the special-shaped ring 301 , thereby allowing the cross plate 302 to move more smoothly along the special-shaped ring 301 .

[0038] Please see attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Fig. 9 The hot pressing mechanism 4 includes a U-shaped frame 401, the bottom ends of the U-shaped frame 401 are fixedly connected to the two sides of the rear top of the chassis 1, a horizontal plate 402 is arranged inside the U-shaped frame 401, the front and rear parts of the top of the U-shaped frame 401 are fixedly connected with hydraulic rods 403, the output ends of the front and rear hydraulic rods 403 are fixedly connected to the top of the horizontal plate 402, the front and rear sides of the bottom end of the horizontal plate 402 are rotatably connected with a rotating plate 404, a T-shaped plate 405 is fixedly connected to the middle part of the bottom end of the horizontal plate 402, the two sides of the T-shaped plate 405 are slidably connected to the two sides inside the front and rear rotating plates 404, and through grooves 406 are opened on both sides of the U-shaped frame 401.

[0039] The U-shaped frame 401 can provide support for the hydraulic rod 403, and then the hydraulic rod 403 can be used to push the second horizontal plate 402 and its connecting parts to move downward when the clothing moves to the thermal transfer station on the rear side of the chassis 1 along with the L-shaped plate 203, the rotating rod 209, etc. When the second rotating plate 404 moves down a certain distance along with the second horizontal plate 402, it can contact the clothing. Since the second rotating plate 404 is tilted at a certain angle as a whole, the second rotating plates 404 on the front and rear sides can rotate and move away from each other along the surface of the clothing when the second horizontal plate 402 continues to move downward, so as to further smooth the clothing and ensure the subsequent transfer effect. The through slot 406 can be used to allow the thermal transfer paper to pass through the U-shaped frame 401 and be located directly above the clothing. In addition, as the rotation amplitude of the second rotating plate 404 increases, the T-shaped plate 405 connected to the second horizontal plate 402 can gradually move downward to contact the thermal transfer paper, and drive the thermal transfer paper to move slightly downward under heating and pressurization conditions to effectively contact the clothing. When the transfer is completed, as the hydraulic rod 403 drives the second horizontal plate 402, the second rotating plate 404, and the T-shaped plate 405 to return to the initial position, the thermal transfer paper can also move a certain distance with the cooperation of the relevant winding parts, thereby preparing for subsequent transfer again.

[0040] Please see attached Fig. 9 The front and rear sides of the top of the U-shaped frame 401 are fixedly connected with connecting plates 407, the sides of the front and rear connecting plates 407 that are close to each other are fixedly connected with springs 408, the sides of the front and rear springs 408 that are close to each other are fixedly connected with slide plates 409, the tops of the front and rear slide plates 409 are slidably connected to the top of the U-shaped frame 401, the ends of the front and rear slide plates 409 that are close to each other are rotatably connected with push plates 410, the sides of the push plates 410 that are close to each other are rotatably connected to the sides of the front and rear rotating plates 404 that are away from each other, and the bottoms of the front and rear rotating plates 404 are rotatably connected to rollers 411 on both sides.

[0041] The connecting plate 407 can provide support for the spring 408, and the spring 408 can push the slide plate 409 to approach each other along the U-shaped frame 401, and the push plate 410 connected to the slide plate 409 can rotate to apply a thrust to the rotating plate 404 to move closer to each other, so as to ensure that when the subsequent roller 411 contacts the clothes, the clothes can be effectively pressed by the combined action of the spring 408 and the hydraulic rod 403, and then when the rotating plate 404 and the roller 411 move along the clothes, the roller 411 can effectively smooth out any wrinkles that may exist.

[0042] Working principle: when in use, the thermal transfer paper roll and the winding roll are installed on both sides of the U-shaped frame 401, and the through slot 406 is used to make the thermal transfer paper pass through the U-shaped frame 401 and be above the rear L-shaped plate 203 and the horizontal plate 303. At the same time, the garment to be transferred is manually put on the outside of the front rotating rod 209 and the rubber sleeve 214 to ensure that the rotating rod 209 and the rubber sleeve 214 can effectively contact the garment from both sides inside the garment, and the opening side of the garment also needs to contact the round table 213 to limit the placement position of the garment, and then start the servo motor 201 so that the turntable 202 can drive the evenly distributed L-shaped plates 203 and the rotating rod 209 to intermittently rotate 90 degrees. When the L-shaped plate 203 rotates, the cross plate 302 connected thereto can be connected to the special-shaped plate 203 through the roller 311. The cross plate 302 can push the horizontal plate 1 303 to move upward along the L-shaped plate 203 until the upper surface of the horizontal plate 1 303 is flush with the rotating rod 209, so that the pattern on the surface of the thermal transfer paper can be transferred to the surface of the clothing by squeezing between the horizontal plate 1 303 and the T-shaped plate 405. As the horizontal plate 1 303 moves upward, the rotating plate 1 304 connected thereto can rotate to pull the vertical plate 305 and the trapezoidal block 1 306 along the L-shaped plate 203 to approach the trapezoidal block 2 307, and then the trapezoidal block 2 307 can drive the arc plate 308 under the guidance of the guide plate 309 and the guide rod 310 through the inclined surface between the trapezoidal block 1 306 and the trapezoidal block 2 307. 209, so that the clothes are not easily moved away from the rotating rod 209. The rotating rod 209 is moved upward to contact the rotating rod 209 through the clothes, so as to support the rotating rod 209 and prevent it from shaking, and at the same time exert a certain pressure on the clothes, so as to prevent the clothes from sliding off the rotating rod 209 due to the airflow generated by the impeller 206 under the cooperation of the lines on the surface of the arc plate 308 that are perpendicular to the direction of the rotating rod 209, and because the rotating rod 209 and the arc plate 308 are relatively smooth, and the lines are perpendicular to the rotating rod 209, they will not affect the clothes from rotating with the rotating rod 209 and the rubber sleeve 214. When the fixing mechanism 3 completes the fixing of the clothes and the camera 211 finds that the clothes are skewed, the servo motor 205 is started, so that the impeller 206 can rotate quickly to generate airflow. At this time, the airflow can be used to blow the clothes from the opening side of the clothes to make the clothes The garment expands to a certain extent, and as the garment expands, the distortion and deflection existing when it is sleeved on the surface of the rotating rod 209 can be restored to a straight state by itself. At the same time, the reinforcing plate auxiliaryly connecting the impeller 206 and the driving wheel 207 can be used to enable the driving wheel 207 to effectively drive the driven wheel 208 to rotate, so that the rotating rod 209 can drive the rubber sleeve 214 to rotate stably under the common support of the round table 213, the L-shaped plate 203 and the arc plate 308, and the friction between the rubber sleeve 214 and the garment can make the garment restored to a straight state rotate synchronously with the rotation of the rotating rod 209 and the rubber sleeve 214 until the side seams on both sides of the garment are in the same horizontal plane. At this time, the garment can be in a standard position, and subsequent garments can also be in the same position after the above process.Thus, the consistency of the subsequently transferred pattern can be ensured. At the same time, the number of teeth on the driven wheel 208 is much larger than that on the driving wheel 207 to prevent the rotating rod 209 from rotating too fast. As the turntable 202 and the L-shaped plate 203 rotate again, the adjusted clothing can be moved to the thermal transfer station on the rear side of the chassis 1. The hydraulic rod 403 can be used to make the second horizontal plate 402 drive the second rotating plate 404 and the T-shaped plate 405 close to the upper surface of the clothing. When the second rotating plate 404 contacts the clothing, due to its own certain inclination angle, as the second horizontal plate 402 continues to move downward, the second rotating plate 404 can rotate. Apply thrust to the push plate 410, and then apply compression force to the spring 408 through the slide plate 409 moving along the U-shaped frame 401. Conversely, under the joint action of the spring 408 and the hydraulic rod 403, the second rotating plate 404 can always effectively contact the clothes through the roller 411, and then effectively smooth out the wrinkles that may exist due to the airflow during the downward movement of the second horizontal plate 402, and then use the heated T-shaped plate 405 to push the thermal transfer paper to bend slightly and contact with the smoothed clothes, and with the cooperation of the horizontal plate 1 303, a certain pressure can be applied to the clothes, thereby completing the thermal transfer.
