Description

Technical Field

[0001] The invention relates to the field of cold-ironing composite equipment, and in particular to a cold-ironing composite machine for cold-ironing metal sheets. Background Art

[0002] Cold foil lamination is a processing method that transfers the pattern on the transfer film to the substrate, which can effectively improve the aesthetics of the substrate. Most of the current cold foil lamination machines are for cold foil lamination processing with soft paper or hard cardboard as the substrate. They generally use a winding and unwinding roller (for soft paper) or a clamping chain (for hard cardboard) to convey the substrate, and cooperate with the transfer film winding and unwinding device and the pressing and laminating device to achieve cold foil lamination processing; this type of cold foil lamination machine is also used for substrates such as plastic sheets or metal plates. However, due to the high density and hard material of metal plates, the conventional conveying method of clamping chains used for hard cardboard cannot effectively convey metal plates. The clamping chain and the metal plate are prone to slippage and misalignment, which not only affects the conveying efficiency, but also easily causes the pattern on the transfer film to be unable to be accurately transferred to the corresponding position on the metal plate due to unstable conveying speed. Summary of the invention

[0003] The purpose of the present invention is to provide a cold foil laminating machine for cold foiling metal sheets, and more particularly to provide a cold foil laminating machine which can effectively and stably transport metal sheets as substrates to improve the efficiency and quality of cold foil laminating.

[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cold stamping laminating machine for cold stamping metal sheets, comprising a metal sheet conveying device, a transfer film winding and unwinding device and a pressing and laminating device, the metal sheet conveying device comprising a pushing conveying device and a conveyor belt, the pushing conveying device is arranged in the upward direction of the pressing and laminating device, and the conveyor belt is arranged in the downward direction of the pressing and laminating device; the pushing conveying device comprises a roller conveying line, a circulating drive chain arranged on both sides of the roller conveying line and a pushing cross bar fixedly arranged between the circulating drive chains, the pushing cross bar is located on the roller conveying line to push and convey the metal sheet.

[0005] Specifically, the pushing cross bar comprises a connecting frame and a rod body, the connecting frame is fixedly connected to one side of the circulating driving chain, and the rod body is fixedly connected to the connecting frame.

[0006] Furthermore, clamping springs are provided at both ends of the rod body, and a pressing roller is provided above the head end of the push conveying device.

[0007] Specifically, the clamping spring sheet comprises a connecting portion, a clamping portion facing inwards and an inlet portion facing outwards in sequence along the conveying direction of the push conveying device.

[0008] Preferably, a buffer layer is provided on the surface of the rod body and the clamping spring.

[0009] Specifically, the pressing roller includes a pressing driving mechanism and a rotating roller, and the pressing driving mechanism is drivingly connected to the rotating roller through a roller connecting seat.

[0010] Specifically, a pressure sensor is provided on one side of the rod body used to push the metal sheet, and the pressure sensor is connected to a controller of the pressing roller.

[0011] The beneficial effects of the present invention are as follows: by arranging a pushing and conveying device in the upward direction of the pressing and compounding device, the metal sheet is pushed and conveyed by utilizing a circulating driving chain in cooperation with the structure of a pushing cross bar, thereby ensuring that the metal sheet can be conveyed forward at a stable speed, improving the efficiency and quality of cold stamping and compounding, and avoiding the problem that the pattern on the transfer film cannot be accurately transferred to the corresponding position on the metal sheet due to slippage between the conveying device and the metal sheet.

[0013] Example 1, reference Figure 1-2 A cold stamping laminating machine for cold stamping metal sheets comprises a metal sheet conveying device, a transfer film unwinding device 1 and a pressing and laminating device 2, wherein the metal sheet conveying device comprises a pushing and conveying device 3 and a conveying belt 4, wherein the pushing and conveying device 3 is arranged in the upward direction of the pressing and laminating device 2, and the conveying belt 4 is arranged in the downward direction of the pressing and laminating device 2; the pushing and conveying device 3 comprises a roller conveying line 31, a circulating driving chain 32 arranged on both sides of the roller conveying line 31 and a pushing cross bar 33 fixedly arranged between the circulating driving chains 32, wherein the pushing cross bar 33 is located on the roller conveying line 31 to push and convey the metal sheet 10.

[0014] In this embodiment, the metal sheet conveying device is used to convey the substrate of the metal sheet 10 so that it enters the pressing and compounding device 2 and is cold-ironized with the transfer film, and the transfer film reeling and unreeling device 1 is used to reel the transfer film so that the transfer film passes through the pressing and compounding device 2 and transfers the pattern thereon to the substrate. The metal sheet conveying device includes a pushing and conveying device 3 and a conveyor belt 4, wherein the pushing and conveying device 3 is arranged in the upward direction of the pressing and compounding device 2, and the pushing and conveying device 3 uses a circulating driving chain 32 to drive the pushing cross bar 33 to push and convey the metal sheet 10 on the roller conveyor line 31, which can effectively ensure that the metal sheet 10 can be conveyed forward at a uniform and stable speed, and there will be no problem of slipping between the conveying device and the metal sheet. Both ends of the pushing cross bar 33 are fixedly set on the circulating drive chain 32. In order to prevent the height of the pushing cross bar 33 from being offset, limit plates are set on the upper and lower sides of the circulating drive chain 32 to avoid the problem that the horizontal height of the pushing cross bar 33 is inconsistent and the metal sheet 10 cannot be pushed due to the up and down shaking of the circulating drive chain 32. Setting limit plates on the upper and lower sides of the circulating drive chain 32 is a conventional processing method for the circulating drive chain in this field and will not be elaborated here.

[0015] Specifically, in this embodiment, the push cross bar 33 includes a connecting frame 331 and a rod body 332, wherein the connecting frame 331 is fixedly connected to one side of the circulating drive chain 32, and the rod body 332 is fixedly connected to the connecting frame 331. The connecting frame 331 is used to be fixedly connected to the side of the circulating drive chain 32, so that the push cross bar 33 can move with the movement of the circulating drive chain 32.

[0016] In a further embodiment, the two ends of the rod body 332 are further provided with clamping springs 333, and a pressing roller 5 is provided above the head end of the push conveying device 3. By providing the clamping springs 333 at both ends of the rod body 332, the metal sheet 10 can be clamped and fixed in the process of the rod body 332 pushing the metal sheet 10 to move, so as to avoid the situation that when deceleration is required during the movement, the metal sheet 10 moves forward under inertia and separates from the rod body 332 due to excessive deceleration. In order to enable the clamping spring 333 to clamp the metal sheet 10, a pressing roller 5 is arranged above the pushing and conveying device 3. The pressing roller 5 is used to press the metal sheet 10 first, and then the circulating driving chain 32 drives the rod body 332 and the clamping spring 333 to move toward the metal sheet 10, so that after the clamping spring 333 clamps the metal sheet 10, the pressing roller 5 releases the metal sheet 10 so that it can be normally conveyed. Since the clamping spring 333 clamps the metal sheet 10 in a small portion, its fixing force on the metal sheet 10 is also small, so it is also convenient for the metal sheet 10 to be separated from the clamping spring 333 and enter the conveying belt 4 for conveying after passing through the pressing composite device 2. Specifically, the clamping spring 333 includes a connecting portion 3331, a clamping portion 3332 facing the inside, and an entrance portion 3333 facing the outside in sequence along the conveying direction of the pushing and conveying device 3.

[0017] Specifically, the pressing roller 5 includes a pressing drive mechanism 51 and a rotating roller 52. The pressing drive mechanism 51 is connected to the rotating roller 52 through a roller connecting seat 53. The pressing drive mechanism 51 drives the rotating roller 52 so that the rotating roller 52 can move downward to press the metal sheet 10 or move upward to release the metal sheet 10. In addition, a pressure sensor (not shown in the figure) is provided on one side of the rod body 332 used to push the metal sheet 10. The pressure sensor is connected to the controller of the pressing roller 5. After the metal sheet 10 is completely clamped by the clamping spring 333, it will contact the rod body 332. By providing a pressure sensor on the side of the rod body 332 used to push the metal sheet 10, it can be detected whether the metal sheet 10 is clamped by the clamping spring 333. When it is detected that the clamping spring 333 has completed clamping the metal sheet 10, the controller of the pressing roller 5 can control the pressing roller 5 to move upward to release the metal sheet 10 for normal conveying.

[0018] Preferably, in this embodiment, a buffer layer 6 is provided on the surface of the rod body 332 and the clamping spring 333. By providing the buffer layer 6, it is possible to prevent the rod body 332 and the clamping spring 333 from directly colliding with the metal sheet 10 and causing damage to the metal sheet 10. The buffer layer can be made of rubber material.

[0019] Of course, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
