[0030] Example 1
[0031] like Figure 1 As shown, a protective cover for a printing press includes a cover body, one end of which is an unwinding end and the other end is a paper output end. The unwinding end has an opening and an operating side cover 1 and a transmission side cover 2 are arranged opposite to each other on both sides of the opening. The paper output end is a paper output side cover 3, and a paper output port 4 is provided on the paper output side cover 3.
[0032] The side of the protective cover body is the operation panel cover 5.
[0033] The beneficial effects of this embodiment are: the protective cover protects the printing press, gears, motors and couplings, preventing equipment from injuring people and protecting the safety of external operators. The protective cover has a simple appearance and facilitates human-machine interaction.
[0034] Specifically, ordinary heat transfer printing machines have a bulky appearance, making it inconvenient for staff to operate them. In this embodiment, the protective cover fits tightly against the outer wall of the printing machine and encloses the printing machine, rollers, gears, motors, and couplings, improving safety and providing dust protection. The control panel cover 5 is equipped with control buttons for easy operation.
[0035] The top of the operating side cover 1 and the transmission side cover 2 are provided with steps for mounting the unwinding shaft 13. A bearing seat is provided on the step. The two ends of the unwinding shaft 13 are rotatably mounted on the bearing seat. The paper roll is mounted on the unwinding shaft 13. The paper roll enters the printing press through the opening and exits from the paper outlet 4 on the other side after passing through the printing press. The transmission side cover 2 is provided with a power source that drives the unwinding shaft 13 to rotate.
[0036] In addition, the protective cover has a perimeter around the sides near the ground to prevent rats and other animals from entering the printing press and to protect the equipment.
[0037] The protective cover body is also provided with horizontal sliding grooves on the sides near the ground. The top edge of the cover is slidably installed in the horizontal sliding grooves and can be slid away to facilitate staff to inspect the interior.
[0038] Example 2
[0039] like Figure 1 As shown, preferably, based on embodiment 1, the operation panel cover 5 has an upper opening and a lower opening sequentially from top to bottom, an upper door 6 is hinged to the upper opening, and a lower door 7 is hinged to the lower opening.
[0040] The advantages of the preferred solution in the above embodiments are: the lower opening is used to adjust the printing pressure of the internal printing press, and the upper opening is used for replacing the carbon ribbon, passing the rubber roller, and cleaning the inkjet nozzle.
[0041] Example 3
[0042] like Figure 1 As shown, preferably, based on embodiments 1-2, the inner side of the top-opening door 6 is provided with a magnet for attracting the top-opening door 6.
[0043] The advantages of the preferred solution in the above embodiments are: since the top-opening door 6 needs to be opened and closed frequently, the use of magnets for attraction makes opening and closing convenient, reduces wear, and extends service life.
[0044] As a parallel technical solution in this embodiment, the magnet can also be replaced by a snap-fit lock.
[0045] Example 4

[0050] The advantages of adopting the preferred solution in the above embodiments are: the printing pressure is generally not changed after it is set, so it does not need to be adjusted frequently; the bottom door 7 is normally closed; and the lock 9 protects the internal equipment and prevents accidental contact.
[0051] Example 6
[0052] like Figure 1 As shown, preferably, based on embodiments 1-5, the top of the protective cover body is provided with a top opening, and an upper cover plate 10 is hinged to the top opening, and an observation window 11 is provided on the upper cover plate 10.
[0053] The beneficial effect of adopting the preferred solution in the above embodiments is that the upper cover plate 10 is used to facilitate the replacement of carbon belts and to observe the internal operation, so as to obtain the equipment status in a timely manner.
[0054] Specifically, the top cover 10 is hinged to the top of the protective cover body.
[0055] Example 7
[0056] like Figure 1 As shown, preferably, based on embodiments 1-6, the upper cover plate 10 is provided with a second handle 12.
[0057] The advantage of adopting the preferred solution in the above embodiments is that it makes it easier for operators to grip the top cover plate 10.
[0058] Example 8

[0060] The advantages of the preferred solution in the above embodiments are: the upper cover plate 10 is opened and closed by a gas spring, which is convenient to use and reduces the labor intensity of operators.
[0061] Specifically, gas springs work on a similar principle to piston rods. An inert gas or oil-gas mixture is filled into a sealed pressure cylinder, making the pressure inside the cavity several times or tens of times higher than atmospheric pressure. The piston rod moves by utilizing the pressure difference generated by the cross-sectional area of the piston rod being smaller than that of the piston. It mainly serves functions such as support, buffering, braking, height adjustment, and angle adjustment.
[0062] The gas spring base is hinged to the inside of the cover body, and the extension end of the gas spring is hinged to the inner wall of the upper cover plate 10 to push the upper cover plate 10 to open and close.

[0064] Example 9
[0065] like Figure 1 As shown, preferably, based on embodiments 1-8, the top-opening door 6 and the bottom-opening door 7 are hinged to the protective cover body.
[0066] The advantages of the preferred solution in the above embodiments are: the use of hinge connection provides strong stability, is not easily damaged, has a silent effect, and reduces noise pollution.
[0067] Example 10
[0068] like Figure 1 As shown, preferably, based on embodiments 1-9, the material of the protective cover body is any one of galvanized sheet, cold-rolled sheet, or stainless steel.
[0069] The beneficial effect of adopting the preferred solution in the above embodiments is that it is selected according to the on-site working environment, thus ensuring the life of the protective cover body.
[0070] Specifically, there is a wide variety of materials to choose from for the lathe housing, including plastic, aluminum alloy, steel plate, and more.
