[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-8 In this embodiment of the present invention, a multi-station transfer heat press machine includes a turntable 2, a sticker feeding component 3 is provided on one side of the turntable 2, and a finished product transfer component 5 is provided on the opposite side of the sticker feeding component 3; a heat printing component 4 is provided between the sticker feeding component 3 and the finished product transfer component 5, and the heat printing component 4 is located on one side of the turntable 2.

[0035] The sticker feeding assembly 3 includes a bracket 38 fixed to the frame 1. A C-shaped mounting bracket 37 is connected to the inner side of the bracket 38, which can be connected by welding, riveting, or bolting. This bracket supports and fixes the rotary cylinder 36. The rotary cylinder 36 is fixedly installed in the middle of the C-shaped mounting bracket 37, and the rotation shaft of the rotary cylinder 36 is fixedly connected to the cylinder mounting seat 35. A lifting cylinder 34 is snapped onto the outer side of the cylinder mounting seat 35, and both sides are fixed with bolts. An L-shaped bracket 33 is fixed to the end of the cylinder rod of the lifting cylinder 34. A mounting bracket 32 ​​is snapped onto the inner side of the L-shaped bracket 33 and fixed with bolts. A negative pressure suction nozzle 31 is installed on the L-shaped bracket 33. The negative pressure suction nozzle 31 is connected to a negative pressure pipeline, which is then connected to a negative pressure generator or a vacuum pump to form a negative pressure. A solenoid valve is connected in series on the negative pressure pipeline to control the flow of negative pressure gas, thereby achieving the sticker adsorption action. The negative pressure control method is existing technology and will not be described in detail here.

[0036] In this embodiment, the top of the bracket 38 is provided with an opening groove 310, and multiple baffles 311 are fixed around the upper end of the opening groove 310. The inner side of the multiple baffles 311 is provided with stickers 312.

[0037] By adopting the above technical solution, stacks of stickers 312 are placed between multiple baffles 311. When feeding the stickers, the rotary cylinder 36 drives the cylinder mounting base 35 and the lifting cylinder 34 to rotate 180 degrees, causing the negative pressure suction nozzle 31 to face upwards. Then, the cylinder rod of the lifting cylinder 34 extends, allowing the negative pressure suction nozzle 31 to adhere to the bottom sticker in the stack. Negative pressure gas is then introduced, and the negative pressure suction nozzle 31 adsorbs the bottom sticker. Then, the cylinder rod of the lifting cylinder 34 retracts, allowing the sticker to pass through the opening slot 310. Next, the rotary cylinder 36 drives the cylinder mounting base 35 and the lifting cylinder 34 to rotate 180 degrees in the opposite direction, placing the sticker above the vehicle body sticker. The cylinder rod of the lifting cylinder 34 extends, affixing the sticker to the vehicle body sticker. The negative pressure of the negative pressure pipe is then turned off, and the cylinder rod of the lifting cylinder 34 retracts, retracting the negative pressure suction nozzle 31.

[0038] The above structure enables continuous feeding of stickers one by one, eliminating the need for manual handling. Furthermore, the sticker feeding component 3 ensures that the stickers on the same car body are in the same position each time, thus guaranteeing product consistency.

[0039] In this embodiment, the heat printing assembly 4 includes a sliding frame 41, which is slidably connected to the sliding column 42 and locked in place by bolts; a fixed seat 44 is fixed at one end of the sliding frame 41, and a pressing cylinder 43 is fixedly installed on the fixed seat 44; the cylinder rod of the pressing cylinder 43 passes through the pressing cylinder 43 and is connected to the drive plate 45.

[0040] Springs 46 are fixed at the four corners of the bottom of the drive plate 45, and the lower end of the springs 46 is fixedly connected to the pressing plate 47.

[0041] More specifically, the pressing plate 47 is an electrically heated metal plate with a cavity inside. The cavity contains a thermocouple, a resistance temperature detector, or a heating wire, which transfers the sticker through heating.

[0042] By adopting the above technical solution, when the vehicle body sticker with the attached sticker rotates to below the pressing plate 47, the cylinder rod of the pressing cylinder 43 extends, pushing the drive plate 45 downward. Connected by the spring 46, the pressing plate 47 presses against the sticker and the vehicle body sticker, thus realizing the heat transfer and heat painting process of the sticker. The heat of the pressing plate 47 is precisely controlled by thermocouples to ensure that the sticker pattern is clear and does not damage the surface of the vehicle body sticker. Subsequently, the cylinder rod of the pressing cylinder 43 retracts, the drive plate 45 moves upward, and the pressing plate 47 separates from the vehicle body sticker, completing an efficient and precise heat transfer operation. This automated process not only improves production efficiency but also significantly reduces the error rate of manual operation, ensuring high-quality output of each product. At the same time, the equipment is easy to maintain, operates stably, further extending the equipment's service life and reducing production costs.

[0043] Meanwhile, the spring 46 effectively buffers the impact force during the pressing process, protects the integrity of the stickers and vehicle wraps, extends the service life of equipment components, and improves the stability and reliability of the overall production line.

[0044] In addition, the sliding frame 41 can slide up and down along the sliding column 42, and the height of the sliding frame 41 relative to the turntable 2 can be adjusted according to actual needs.

[0045] In this embodiment, the finished product transfer component 5 includes a negative pressure adsorption block 51; the upper end of the negative pressure adsorption block 51 is connected to the hanger 52 via a hanger rod 53; one end of the hanger 52 is fixed to the cylinder rod of the feeding cylinder 54; the feeding cylinder 54 is connected to the rodless cylinder 56; the rodless cylinder 56 is installed in the middle inside the adjustment frame 55.

[0046] The adjustment bracket 55 is slidably connected inside the slide 57 and fixed by bolts.

[0047] More specifically, the bottom of the negative pressure adsorption block 51 has multiple negative pressure adsorption holes, and its top is connected to a negative pressure tube through a quick connector for the introduction of negative pressure gas; the process of negative pressure adsorption of the car body sticker is the same as the working principle of the sticker feeding component 3.

[0048] By adopting the above technical solution, when the car body sticker that has been heat-pressed is rotated to the bottom of the negative pressure adsorption block 51, the cylinder rod of the feeding cylinder 54 is pushed out, so that the negative pressure adsorption block 51 adsorbs the car body sticker; then the cylinder rod of the feeding cylinder 54 retracts, and the rodless cylinder 56 drives the feeding cylinder 54 to slide outward until the negative pressure adsorption block 51 is above the receiving box 6, then the negative pressure is turned off, and the processed car body sticker falls into the receiving box 6.

[0049] This process enables automatic product unloading, eliminating the need for manual handling of the processed products, effectively reducing the labor intensity of workers and greatly improving the efficiency of heat transfer printing on vehicle wraps.

[0050] In this embodiment, the bottom of the turntable 2 is connected to the power output end of the reducer 7, and the power input end of the reducer 7 is connected to the drive motor 8 through the pulley 9 and the belt 10; then the reducer 7 and the drive motor 8 are fixed to the frame 1.

[0051] By adopting the above technical solution, the drive motor 8, in cooperation with the pulley 9 and the belt 10, transmits power to the reducer 7, which in turn drives the turntable 2 to rotate, thereby realizing the alternating work between multiple workstations and effectively improving work efficiency.

[0052] In this embodiment, multiple positioning frames 11 are arranged in a circular array above the turntable 2.

[0053] By adopting the above technical solution, the positioning frame facilitates quick positioning of the vehicle body sticker during placement, ensuring the consistency of the angle and position of each sticker, thereby guaranteeing the consistency of the same batch of products.

[0054] In this embodiment, a receiving box 6 is also provided below the turntable 2 on one side of the finished product transfer component 5, and the receiving box 6 is placed on the frame body 1.

[0055] The working principle of this utility model is as follows: The vehicle sticker is placed in the positioning frame. The drive motor 8, in conjunction with the pulley 9 and belt 10, transmits power to the reducer 7. The reducer 7 then drives the turntable 2 to rotate, placing stacks of stickers 312 between multiple retainers 311. When feeding the stickers, the rotary cylinder 36 drives the cylinder mounting base 35 and the lifting cylinder 34 to rotate 180 degrees, causing the negative pressure suction nozzle 31 to rise. Subsequently, the cylinder rod of the lifting cylinder 34 extends, allowing the negative pressure suction nozzle 31 to... The bottom sticker in the stack of stickers is attached, then negative pressure gas is introduced, and the negative pressure suction nozzle 31 suctions the bottom sticker. Then the cylinder rod of the lifting cylinder 34 retracts, allowing the sticker to pass through the opening slot 310. Next, the rotating cylinder 36 drives the cylinder fixing seat 35 and the lifting cylinder 34 to rotate 180 degrees in the opposite direction, placing the sticker above the car body sticker. The cylinder rod of the lifting cylinder 34 extends, attaching the sticker to the car body sticker. The negative pressure of the negative pressure pipe is closed, and the cylinder rod of the lifting cylinder 34 retracts, retracting the negative pressure suction nozzle 31.

[0056] When the vehicle decal with the sticker attached rotates to below the pressing plate 47, the piston rod of the pressing cylinder 43 extends, pushing the drive plate 45 downward. Connected by the spring 46, the pressing plate 47 presses against the sticker and the vehicle decal; thus achieving the heat transfer and heat painting process for the sticker. The heat of the pressing plate 47 is precisely controlled by a thermocouple, ensuring the sticker pattern is clear and does not damage the surface of the vehicle decal. Subsequently, the piston rod of the pressing cylinder 43 retracts, the drive plate 45 moves upward, and the pressing plate 47 separates from the vehicle decal, completing an efficient and precise heat transfer operation.

[0057] When the car body sticker that has been heat-pressed is rotated to a position below the negative pressure adsorption block 51, the cylinder rod of the feeding cylinder 54 extends, causing the negative pressure adsorption block 51 to adsorb the car body sticker; then the cylinder rod of the feeding cylinder 54 retracts, and the rodless cylinder 56 drives the feeding cylinder 54 to slide outward until the negative pressure adsorption block 51 is above the receiving box 6, at which point the negative pressure is turned off, and the processed car body sticker falls into the receiving box 6.
