Description

Technical Field

[0001] This utility model belongs to the field of rain boot printing technology, and more specifically, it relates to a cold transfer decal machine. Background Technology

[0002] A cold transfer decal machine is a device specifically designed to transfer patterns or designs from transfer paper to the surface of a target object. Its main characteristic is that it utilizes pressure and adhesive at low or room temperature to complete the transfer process, unlike heat transfer which relies on high temperatures. This type of machine is widely used for decoration and personalization of various materials such as textiles, plastics, leather, and ceramics, and is particularly common in the production of footwear products such as rain boots and athletic shoes. Existing cold transfer decal machines typically perform the transfer on a flat plate when transferring decals onto the boot shaft of rain boots.

[0003] Based on the above, existing cold transfer decal machines typically perform the cold transfer on a flat plate when transferring decals onto the boot shaft of rain boots. This method has several significant drawbacks. First, since the shape of the boot shaft is usually elliptical, and the flat plate cannot fully conform to this curved surface, uneven pressure distribution occurs during the transfer process, easily resulting in incomplete or blurry transfer of the pattern. Second, after the cold transfer decal is completed on the flat plate, releasing the pressure plate can easily cause wrinkles or bubbles in the pattern due to the bending characteristics of the boot shaft, affecting the final transfer effect and product quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cold transfer decal machine to address the issue that in existing cold transfer decal machines, the pattern easily wrinkles after the pressure plate is released on the rain boot shaft after the cold transfer decal has been transferred onto a flat plate.

[0005] The purpose and effect of this utility model's cold transfer decal machine are achieved through the following specific technical means:

[0006] A cold transfer decal machine, comprising:

[0007] Device housing;

[0008] A printing operation handle, the output end of which is rotatably connected to the left end face of the device housing;

[0009] The rain boot cover block has an elliptical structure. The left end of the rain boot cover block is fixedly installed on the left inner wall of the device housing, and the center of the right end face of the rain boot cover block is concentrically fixedly connected to the output end of the printing operation handle.

[0010] Rain boots to be printed, wherein the boot shaft of the rain boots to be printed is inserted into the rain boot cover block;

[0011] A pressure regulating handwheel, the output end of which is rotatably connected to the front end face of the top of the device housing;

[0012] A pressure regulating plate, wherein two cylindrical structures are provided on the left and right sides of the bottom of the pressure regulating plate, and the pressure regulating plate is movably connected to the lower end face of the top of the device housing;

[0013] The roller support frame consists of two cylindrical structures. The diameter of the two roller support frames is larger than the diameter of the two cylindrical structures located on the left and right sides of the bottom of the two pressure regulating plates. The two roller support frames are slidably connected to the two cylindrical surfaces located on the left and right sides of the bottom of the two pressure regulating plates.

[0014] A pressure roller, which is rotatably connected between two roller support frames;

[0015] A cold transfer assembly, wherein the cold transfer assembly is disposed on the front side of the exterior of the device housing;

[0016] A pressure regulating assembly is disposed inside the top of the device housing.

[0017] Furthermore, the cold transfer component includes:

[0018] Rain boot decals are inserted into the surface of the boot shaft of the rain boot to be printed, and the outer surface of the rain boot decals rolls in contact with the cylindrical surface of the pressure roller.

[0019] Furthermore, the cold transfer assembly also includes:

[0020] The pressure spring consists of two springs. The upper ends of the two springs are concentrically fixed to the upper ends of two cylindrical structures located on the left and right sides of the bottom of the pressure adjusting plate. The lower ends of the two springs are elastically connected to the upper end faces of two roller support frames.

[0021] Furthermore, the pressure regulating component includes:

[0022] A drive bevel gear, which is concentrically and fixedly connected to the output end of the pressure regulating handwheel;

[0023] The driven bevel gear meshes above the driving bevel gear, and the driving bevel gear and the driven bevel gear together constitute a bevel gear transmission mechanism.

[0024] Furthermore, the pressure regulating assembly also includes:

[0025] A driving cylindrical gear is concentrically fixedly connected to the upper end face of the driven bevel gear;

[0026] The driven cylindrical gear is a gear structure with a threaded through hole at its center. There are two driven cylindrical gears, which mesh on the left and right sides of the driving cylindrical gear respectively. The driving cylindrical gear and the driven cylindrical gear together form a gear transmission mechanism and the two driven cylindrical gears rotate in the same direction.

[0027] Furthermore, the pressure regulating assembly also includes:

[0028] The pressure adjusting screw consists of two parts, which are symmetrically distributed on the left and right and rotatably connected to the upper end face of the pressure adjusting plate. The two pressure adjusting screws are respectively engaged with the threaded through hole opened at the center of the driven cylindrical gear. The threaded through hole opened at the center of the driven cylindrical gear and the pressure adjusting screw together constitute the screw and nut transmission mechanism.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] First, thanks to its retractable pressure roller design, this new machine better adapts to the oval shape of the rain boot shaft, ensuring uniform pressure distribution throughout the transfer process. This not only avoids the problems of uneven pressure that can lead to incomplete pattern transfer or quality degradation in traditional cold transfer processes, but also guarantees consistent transfer results for each rain boot, improving the overall quality and aesthetics of the product.

[0031] Secondly, the integrated pressure adjustment mechanism allows operators to adjust the cold transfer pressure according to the style and material of the rain boots. This means the same machine can adapt to the production needs of various types of rain boots, improving machine efficiency and reducing the additional costs incurred by businesses due to replacing different machine models. Furthermore, this flexible pressure adjustment capability also helps optimize the transfer effect, especially when handling special materials or complex patterns.

[0032] Then, the new type of cold transfer decal machine for rain boots can precisely control the number of rolling compaction cycles through an elliptical contour compaction method. In actual production, if poor transfer is encountered, the number of rolling cycles can be increased to further compact the material, ensuring the pattern is completely transferred to the rain boot. This flexibility not only solves potential problems during the transfer process but also significantly improves the quality and consistency of the finished product, reduces the scrap rate, and thus improves overall production efficiency and economic benefits.

[0033] This invention features a retractable pressure roller design that ensures uniform pressure distribution throughout the transfer process, making it particularly suitable for the elliptical contour of rain boot shafts, thereby improving the uniformity and quality of cold transfer. Secondly, the integrated pressure adjustment component allows operators to flexibly adjust the pressure according to different rain boot types and materials, enhancing the machine's adaptability and flexibility. Finally, the elliptical contour compaction method allows for precise control of the number of rolling compaction cycles. When transfer is unsatisfactory, increasing the number of rolling cycles can achieve the desired transfer effect, ensuring a high yield and high production efficiency. Attached Figure Description

[0041] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0042] Example 1:

[0043] As attached Figure 1 To be continued Figure 5 As shown:

[0044] This utility model provides a cold transfer decal machine, comprising:

[0045] Device housing 15;

[0046] The printing operation handle 12 is rotatably connected to the left end face of the device housing 15 at its output end.

[0047] Rain boot cover 13, which has an elliptical structure, has its left end fixedly installed on the left inner wall of the device housing 15, and its right end face is concentrically fixedly connected to the output end of the printing operation handle 12.

[0048] Printed rain boots 14 are inserted into the boot top of rain boot block 13.

[0049] Pressure adjusting handwheel 7, the output end of pressure adjusting handwheel 7 is rotatably connected to the front end face of the top of device housing 15;

[0050] Pressure regulating plate 10, with two cylindrical structures on the bottom left and right, is movably connected to the lower end face of the top of the device housing 15;

[0051] Roller support frame 11, there are two cylindrical structures of roller support frame 11. The diameter of the two roller support frames 11 is larger than the diameter of the two cylindrical structures set on the bottom left and right of the two pressure regulating plates 10. The two roller support frames 11 are slidably connected to the two cylindrical surfaces set on the bottom left and right of the two pressure regulating plates 10 respectively.

[0052] Pressure roller 9 is rotatably connected between two roller support frames 11;

[0053] A cold transfer component is disposed on the front side of the exterior of the device housing 15;

[0054] Pressure regulating assembly, which is located inside the top of the device housing 15.

[0055] The cold transfer components include:

[0056] Rain boot decal 8 is inserted into the surface of the boot shaft of the rain boot 14 to be printed. The outer surface of the rain boot decal 8 rolls in contact with the cylindrical surface of the pressure roller 9. In use, when using the new device for cold transfer decal printing on rain boots, first, the boot shaft of the rain boot 14 to be printed is fitted onto the rain boot sleeve 13, and then the rain boot decal 8 is pasted onto the surface of the boot shaft of the rain boot 14 to be printed. The printing operation handle 12 is operated to rotate the whole assembly. While rotating, the rain boot decal 8 is subjected to the rolling pressure of the pressure roller 9 above, so that the pattern on the rain boot decal 8 can be cold transferred to the surface of the boot shaft of the rain boot 14 to be printed. At the same time, in order to make the transfer effect better, the printing operation handle 12 can be rotated several more times to make the transferred pattern more even.

[0057] The cold transfer component also includes:

[0058] There are two pressure springs 6. The upper ends of the two pressure springs 6 are concentrically fixed to the upper ends of two cylindrical structures located on the left and right sides of the bottom of the pressure adjustment plate 10. The lower ends of the two pressure springs 6 are elastically connected to the upper end faces of the two roller support frames 11. In use, when the whole consisting of the rain boot cover block 13, the rain boot decal 8, and the rain boot to be printed 14 rotates, the overall shape of the structure is approximately elliptical. When the pressure roller 9 rolls and contacts the raised part of the rain boot decal 8, the pressure spring 6 contracts. When it moves to the flat part, the pressure roller 9 returns to its original position. Its function is to allow the pressure roller 9 to roll and contact the surface of the rain boot decal 8 normally, and at the same time, the pressure spring 6 applies a certain pressure to the pressure roller 9, so that the cold transfer printing function can be realized.

[0059] The pressure regulating component includes:

[0060] The active bevel gear 1 is concentrically fixedly connected to the output end of the pressure regulating handwheel 7;

[0061] Driven bevel gear 2 meshes above the driving bevel gear 1. The driving bevel gear 1 and driven bevel gear 2 together form a bevel gear transmission mechanism. In use, operating the pressure adjusting handwheel 7 drives the driving bevel gear 1 to rotate. Since the driving bevel gear 1 and driven bevel gear 2 together form a bevel gear transmission mechanism, the driven bevel gear 2 rotates. Its function is to transmit the rotation of the pressure adjusting handwheel 7 to the rotation of the driven bevel gear 2.

[0062] The pressure regulating component also includes:

[0063] The driving cylindrical gear 3 is concentrically fixedly connected to the upper end face of the driven bevel gear 2;

[0064] Driven cylindrical gear 4: There are two driven cylindrical gears 4, each with a threaded through hole at its center. The two driven cylindrical gears 4 mesh on the left and right sides of the driving cylindrical gear 3, respectively. The driving cylindrical gear 3 and the driven cylindrical gear 4 together form a gear transmission mechanism, and the two driven cylindrical gears 4 rotate in the same direction. In use, the driven bevel gear 2 rotates, driving the driving cylindrical gear 3. Since the driving cylindrical gear 3 and the driven cylindrical gear 4 together form a gear transmission mechanism, the two driven cylindrical gears 4 rotate. Their function is to transmit the rotation of the driven bevel gear 2 to the rotation of the two driven cylindrical gears 4, while ensuring that the two driven cylindrical gears 4 rotate in the same direction.

[0065] The pressure regulating component also includes:

[0066] There are two pressure adjusting screws 5, which are symmetrically distributed on the left and right and rotatably connected to the upper end face of the pressure adjusting plate 10. The two pressure adjusting screws 5 are respectively engaged with the threaded through hole opened at the center of the driven cylindrical gear 4. The threaded through hole opened at the center of the driven cylindrical gear 4 and the pressure adjusting screw 5 together form a screw and nut transmission mechanism. In use, when the driven cylindrical gear 4 rotates, the threaded through hole opened at the center of the driven cylindrical gear 4 and the pressure adjusting screw 5 together form a screw and nut transmission mechanism, thereby causing the left and right pressure adjusting screws 5 to drive the pressure adjusting plate 10 to move up and down. Its function is to adjust the pressure between the rain boot decal paper 8 and the pressure roller 9 by adjusting the up and down movement of the pressure adjusting plate 10, thereby enabling the device to realize the function of cold transfer printing pressure adjustment.

[0067] The specific usage and function of this first embodiment are as follows:

[0068] In use, when performing cold transfer decal printing on rain boots using the new device, firstly, the boot shaft of the rain boot 14 to be printed is fitted onto the rain boot cover block 13. Then, the rain boot decal paper 8 is pasted onto the surface of the boot shaft of the rain boot 14. Operating the printing operation handle 12 causes the entire assembly to rotate. Simultaneously, the rain boot decal paper 8 is subjected to the rolling pressure of the pressure roller 9 above, allowing the pattern on the rain boot decal paper 8 to be cold transferred to the surface of the boot shaft of the rain boot 14. To improve the transfer effect, the printing operation handle can be operated... 12. Rotating the roller several times makes the transferred pattern more even. When the rain boot cover 13, rain boot decal 8, and the rain boot to be printed 14 are rotated, due to the overall elliptical shape of the structure, the pressure spring 6 contracts when the pressure roller 9 rolls and contacts the raised part of the rain boot decal 8. When it moves to the flat part, the pressure roller 9 returns to its original position. Its function is to allow the pressure roller 9 to roll normally along the surface of the rain boot decal 8, while simultaneously allowing the pressure spring 6 to apply a certain pressure to the pressure roller 9, thus enabling the cold transfer function. In this process, the pressure regulating handwheel 7 drives the driving bevel gear 1 to rotate. Since the driving bevel gear 1 and the driven bevel gear 2 together form a bevel gear transmission mechanism, the driven bevel gear 2 rotates. Its function is to transmit the rotation of the pressure regulating handwheel 7 to the rotation of the driven bevel gear 2. The rotation of the driven bevel gear 2 drives the driving cylindrical gear 3. Since the driving cylindrical gear 3 and the driven cylindrical gear 4 together form a gear transmission mechanism, the two driven cylindrical gears 4 on the left and right rotate. Their function is to transmit the rotation of the driven bevel gear 2 to the rotation of the two driven cylindrical gears on the left and right. The rotation of the driving cylindrical gear 4 causes the two driven cylindrical gears 4 to rotate in the same direction. When the driven cylindrical gear 4 rotates, the threaded through hole at the center of the driven cylindrical gear 4 and the pressure adjusting screw 5 together form a screw and nut transmission mechanism, which causes the two pressure adjusting screws 5 to drive the pressure adjusting plate 10 to move up and down. Its function is to adjust the pressure between the rain boot decal 8 and the pressure roller 9 by adjusting the up and down movement of the pressure adjusting plate 10, thereby enabling the device to realize the function of cold transfer printing pressure adjustment.
