Description

TECHNICAL FIELD

[0001] The utility model relates to a cleaning device, especially apply to a kind of cleaning device of single paper offset printing machine impression cylinder. BACKGROUND

[0002] Figure 1 For the impression cylinder device in prior art, it includes impression cylinder 2a and machine wallboard 1a, machine wallboard 1a is two blocks and is arranged at intervals, and impression cylinder 2a is rotatably arranged between machine wallboard 1a.

[0003] The circumferential surface of the impression cylinder of the offset printing machine will stick dirty ink after working for a certain period of time, thereby affecting the quality of the printed matter, so it is required to clean the circumferential surface of the impression cylinder in time. At present, a cleaning device is generally used to automatically clean, and the basic operation is to install the cleaning device from the front of the impression cylinder, and the cleaning device is installed at a position below the impression cylinder. After cleaning is completed, the cleaning device is moved from the front. Since the space below the impression cylinder is relatively limited, it is relatively troublesome to install and dismount the cleaning device, the working strength of the operator is very large, and there is a safety hazard. UTILITY MODEL CONTENTS

[0004] The first technical problem to be solved by the utility model is to provide an impression cylinder cleaning device mounting structure of an offset printing machine which is convenient to dismount.

[0005] The second technical problem to be solved by the utility model is to provide an impression cylinder cleaning device mounting structure of an offset printing machine which is safe.

[0006] The utility model adopts the technical scheme that an impression cylinder cleaning device mounting structure of an offset printing machine is provided, which comprises an impression cylinder and a machine wallboard. The machine wallboard is two blocks and is arranged at intervals. The impression cylinder is rotatably arranged between the machine wallboard. The machine wallboard is characterized in that at least one of the machine wallboards is provided with a through hole. The cleaning device is arranged below the impression cylinder and can be pulled out from one side of the machine wallboard through the through hole.

[0007] Further, a support frame is arranged on the inner side of the machine wallboard close to the through hole. The cleaning device has two installation plates arranged at intervals. In the state that the cleaning device is arranged below the impression cylinder, the installation plates are arranged in the respective support frames.

[0008] Further, a guide rail is arranged between the support frames. Correspondingly, the installation plates are provided with guide grooves matched with the guide rail below.

[0009] Further, the bottom of the support frame is provided with an installation groove with a port facing upwards. A spring is arranged in the installation groove. The lower end surface of the guide rail is provided with a pad, and the top end of the spring abuts against the pad.

[0010] Further, the support frame is provided with a limiting block for limiting the installation plate.

[0011] Compared with the prior art, the printing cylinder cleaning device has the advantages that: compared with front installation and disassembly, the side pulling design is not limited by the space below the printing cylinder, and is more conducive to the installation and disassembly of the machine body, and does not directly contact the printing cylinder, so that the safety of the operator is high.

[0017] The utility model will be further described in detail below in combination with the embodiment of the drawings.

[0018] As Figures 2-5 shown, the printing cylinder cleaning device of the offset press in the embodiment includes a printing cylinder 2 and a machine wall plate 1, the machine wall plate 1 is two and is arranged at intervals, the printing cylinder 2 is rotatably arranged between the machine wall plate 1, the machine wall plate 1 is provided with a through hole 11, and the printing cylinder 2 is provided below with a cleaner 3, which can be pulled out from one side of the machine wall plate 1 through the through hole 11.

[0019] The inside of the machine wall plate 1 is provided with a support frame 4 close to the through hole 11 through a connecting pin 42, the cleaner 3 has two installation plates 31 arranged at intervals, a cleaning cloth 32 is arranged between the installation plates 31, and the installation plate 31 is arranged in the corresponding support frame 4 in the state that the cleaner 3 is arranged below the printing cylinder 2.

[0020] The support frames 4 are provided with guide rails 41, and correspondingly, the installation plates 31 are provided below with guide grooves 32 matched with the guide rails 41. Figure 5 As shown in the figure, the bottom of the support frame 4 is provided with an installation groove 47 with the port upward, the installation groove 47 is provided with a spring 46, the lower end surface of the guide rail 41 is provided with a pad 44 through a shaft pin 45, and the pad 44 abuts against the top end of the spring 46. The support frame 4 is provided with a limiting block 43 for limiting the installation plate 31.

[0021] When the cleaner 3 is installed, it is downwardly applied to the guide rail 41, the spring 46 is compressed, and the cleaner 3 is pushed out of the through hole 11, so that the installation can be easily completed. After installation, in the vertical direction, due to the action of the spring 42, the cleaner 3 is tightly matched with the support frame 4, and in the transverse direction, it is limited due to the setting of the limiting block 43. When disassembling, first disassemble the limiting block 43, and overcome the elastic force of the spring 46 to pull out the cleaner 3 from the through hole 11 on the side of the machine wall plate.
