Description

Technical Field

[0001] The utility model relates to the technical field of offset printing protective covers, in particular to a protective cover for an offset printing machine. Background Art

[0002] An offset press is a type of lithographic printing press. During printing, the printed image and text are first printed from the printing plate onto a rubber cylinder, and then transferred from the rubber cylinder to the paper. Offset presses can be divided into sheet-fed offset presses and web offset presses according to the different paper feeding methods; they can be divided into single-color, two-color, four-color and multi-color presses according to the number of colors printed in one paper feed; they can be divided into small offset presses, six-opening, four-opening, folio and full-sheet presses according to the maximum paper format. In addition, there are duplex presses that can print on both sides at the same time in one paper feed. Sheet-fed offset presses are lithographic printing presses used to print high-end commercial printed materials and packaging printed materials, and are the mainstream of modern paper printing.

[0003] During the printing process of many offset printing machines, the paper is exposed to the air. Dust and foreign matter falling in the air will affect the final printed product, and people may accidentally touch the paper to affect it. Without protection, the printed product is easily affected by external factors, but it cannot be completely sealed during use to prevent the printed material from being unable to be viewed when needed.

[0004] Therefore, it is urgent to provide a protective cover for an offset printing machine to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the protective cover of a general offset printing machine is used in a relatively simple manner, and cannot isolate dust while preventing accidental contact by outsiders, which will affect the normal printing of printed materials.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: a protective cover for an offset printing machine, comprising a dustproof component, the dustproof component can change the dustproof state by rotating, and can slide and knock to remove dust;

[0007] The bottom of the dustproof component is slidably connected with a base component, the base component is used to position the dustproof component, and the base component and the dustproof component are locked by plugging;

[0008] A clamping assembly is arranged on the outside of the base assembly, and the clamping assembly is clamped on the outside of the offset printing machine to fix the position of the base assembly.

[0009] The utility model is further configured as follows: the dustproof component includes a shell, a plurality of through holes are opened on the top of the shell, filters are embedded in the through holes, hanging plates are provided on both sides of the shell, the base component includes a base frame, vertical plates are provided on both sides of the base frame, the two hanging plates are respectively slidably connected to the two vertical plates, the clamping component includes two clamping plates, the two clamping plates are respectively fixed on both sides of the base frame, and one side of the clamping plate is slidably connected to a sticky plate.

[0010] Through the above technical solution, the sliding adhesive plate can absorb the outer wall of the offset printing machine and the chassis can be installed on the outside of the offset printing machine. At this time, the shell can perform dust-proof treatment on the printed matter. After the chassis is fixed, the upward sliding shell can open a gap between the shell and the chassis. Without disassembling the shell and the chassis, the printed matter can still be checked and intervened from the gap, which is more convenient to use.

[0011] The utility model is further configured as follows: an insert block is slidably connected to one side of the hanging plate, and two slots are provided on one of the vertical plates, and the insert block is adapted to the slots.

[0012] Through the above technical solution, the position of the shell can be limited, so that the position of the shell can be fixed when the shell is in contact with the base frame or when the shell is away from the base frame.

[0013] The utility model is further configured as follows: a rotating hole is provided on the top of the shell, a bracket is rotatably connected in the rotating hole, and a plurality of sockets are provided on the top of the shell, and the sockets are adapted to the brackets.

[0014] Through the above technical solution, the bracket will be connected with multiple sockets at the same time to limit the direction. The bracket is rotatably connected to the rotating hole and slidably connected at the same time. The bracket slides up and rotates to change the direction, and then the bracket slides down and is connected with the socket to limit the position. When the bracket coincides with the through hole, the top of the shell is completely sealed, which has a better dust-proof effect on the shell. However, if it is always in a sealed state, the shell will be too humid due to lack of ventilation. Therefore, changing the direction of the bracket can ventilate the inside of the shell to prevent the offset printing machine from being too humid and causing damage to the printed matter.

[0015] The utility model is further configured as follows: a clamping plate is provided on one side of the clamping plate, a clamping block is provided on one side of the adhesive plate, the clamping block is slidably connected to the clamping plate, a groove is provided on one side of the clamping plate, a baffle is rotatably connected in the groove, and the baffle is hooked and matched with the clamping block.

[0016] Through the above technical solution, the clamping block can be limited when the baffle plate is hung with the clamping block, so that the adhesive plate will not loosen.

[0017] The utility model is further configured as follows: a collision plate is arranged inside the shell, a sliding rod is arranged on one side of the collision plate, and the sliding rod is slidably connected to the shell.

[0018] Through the above technical solution, after removing the shell, the sliding slide rod allows the impact plate to hit the inner wall of the shell to generate vibration, which makes the filter vibrate and shake off the dust for dust removal.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The utility model changes the protective state of the shell by rotating the bracket, which can change the shell from a breathable state to a completely sealed state, and can provide more thorough protection for printed materials when not in use. It is more flexible to use and more practical than ordinary protective covers;

[0021] 2. The utility model allows the housing to be installed outside the offset printing machine through the base frame and the adhesive plate, and at the same time allows the housing to be away from the offset printing machine without being disassembled, so that the housing can be raised to check the printed matter when needed.

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0028] See also Figure 1-Figure 4 , a protective cover for an offset printing machine, comprising a dustproof component 1, the dustproof component 1 can change the dustproof state by rotating, and can slide and knock to remove dust;

[0029] The bottom of the dustproof component 1 is slidably connected with a base component 2, the base component 2 positions the dustproof component 1, and the base component 2 and the dustproof component 1 are locked by plugging;

[0030] A clamping assembly 3 is provided on the outside of the base assembly 2 , and the clamping assembly 3 is clamped on the outside of the offset printing machine to fix the position of the base assembly 2 .

[0031] The dustproof component 1 includes a shell 101, a plurality of through holes 102 are provided on the top of the shell 101, a filter screen 103 is embedded in the through holes 102, a hanging plate 104 is provided on both sides of the shell 101, the base component 2 includes a bottom frame 201, a vertical plate 202 is provided on both sides of the bottom frame 201, and the two hanging plates 104 are respectively slidably connected to the two vertical plates 202, and the clamping component 3 includes two clamping plates 301, and the two clamping plates 301 are respectively fixed on both sides of the bottom frame 201. One side is slidably connected with an adhesive plate 302. The adhesive plate 302 is slid to absorb the outer wall of the offset printing machine so that the chassis 201 can be installed on the outside of the offset printing machine. At this time, the shell 101 can perform dust prevention on the printed matter. After the chassis 201 is fixed, the upward sliding shell 101 can open a gap between the shell 101 and the chassis 201. Without disassembling the shell 101 and the chassis 201, the printed matter can still be checked and intervened from the gap, which is more convenient to use.

[0032] like Figure 2-Figure 3 As shown, one side of the hanging plate 104 is slidably connected with an insert block 105, and two slots 203 are provided on one of the vertical plates 202. The insert block 105 is adapted to the slots 203, and can limit the position of the shell 101, so that the position of the shell 101 can be fixed when the shell 101 is in contact with the base frame 201 or when the shell 101 is away from the base frame 201.

[0033] like Figure 2 As shown, a rotating hole 106 is provided on the top of the shell 101, and a bracket 107 is rotatably connected in the rotating hole 106. A plurality of sockets 108 are provided on the top of the shell 101, and the sockets 108 are adapted to the bracket 107. The bracket 107 is simultaneously plugged into the plurality of sockets 108 to limit the direction. The bracket 107 is rotationally connected to the rotating hole 106 and is also slidably connected. The bracket 107 slides up and rotates to change the direction, and then the bracket 107 slides down and is plugged into the socket 108 to limit the position. When the bracket 107 coincides with the through hole 102, the top of the shell 101 is completely sealed, and the dustproof effect of the shell 101 is better. However, if it is always in a sealed state, the shell 101 will be too humid due to lack of ventilation. Therefore, changing the direction of the bracket 107 can allow ventilation inside the shell 101 to prevent the offset printing machine from being too humid and causing damage to the printed matter.

[0034] like Figure 4As shown, a clamping plate 303 is provided on one side of the clamping plate 301, and a clamping block 304 is provided on one side of the sticking plate 302.

The baffle 306 is hooked and matched with the clamping block 304. When the baffle 306 is hooked with the clamping block 304, the clamping block 304 can be limited to prevent the sticking plate 302 from loosening.

[0035] like Figure 2 As shown, a collision plate 109 is provided inside the shell 101, and a slide rod 110 is provided on one side of the collision plate 109. The slide rod 110 is slidably connected to the shell 101. After the shell 101 is removed, the slide rod 110 is slid to allow the collision plate 109 to hit the inner wall of the shell 101 to generate vibration, so that the filter 103 vibrates and shakes off the dust for dust removal.

[0036] When the utility model is in use, the base frame 201 is attached to the top of the offset printing machine, and the two clamping plates 301 are attached to the two sides of the offset printing machine, the sliding adhesive plate 302 adsorbs the offset printing machine, and then the baffle 306 is rotated to limit the adhesive plate 302, and the housing 101 is slid and limited by the plug block 105, so that the housing 101 can be fixed at different positions, and the sliding housing 101 can also make it detach from the base frame 201. Under normal circumstances, the top of the housing 101 can be ventilated and the filter 103 can be used for dust removal. The rotating bracket 107 changes direction to seal the through hole 102, so that the housing 101 is better protected.
