Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing equipment, specifically a dust removal device. Background Technology
[0002] The printing industry generates a large amount of dust during the production process, mainly from paper fibers, ink particles, etc. This dust not only affects the printing quality, but may also harm the health of employees and the environment. Printing machines generally have a row of brushes. Due to prolonged use, the bristles on the brushes wear down and become covered with dust. These brushes need to be cleaned and maintained regularly.
[0003] However, since most of the currently installed brushes are fixed in specific locations, it is inconvenient to replace them when they wear out and lose their dust removal function, requiring the production line to be stopped before replacement. Utility Model Content
[0004] In view of the shortcomings of the prior art, the present invention provides a dust removal device that solves the problems mentioned in the background.
[0005] This utility model provides the following technical solution: a dust removal device, including a printing bracket, the printing bracket including a support frame and a dust removal mechanism body, the dust removal mechanism body including a rotating bracket and a movable roller, the outer side wall of the movable roller is provided with a limit socket array, a slot is provided above one end of the limit socket, the end of the limit socket located away from the slot is connected to a toggle lock block through an elastic rotating shaft, a wiping brush is provided inside the limit socket, a locking rod is installed at one end of the wiping brush corresponding to the position of the slot, and a positioning lock hole is provided on the inner side of the other end of the wiping brush.
[0006] As a further embodiment of this utility model: the movable roller is mounted with a ratchet gear on one side of the rotating bracket via a rotating shaft, and a limiting pawl is mounted on the outer side of the ratchet gear on the side surface of the rotating bracket.
[0007] As a further embodiment of this utility model: a transmission roller is provided inside the support frame, a drive mechanism is installed at one end of the transmission roller on the outside of the support frame, and a printing roll is provided on the inside of the transmission roller.
[0008] As a further embodiment of this utility model: the inner diameter of the limiting socket is greater than the outer diameter of the wiping brush, and the limiting socket is fixedly connected to the movable roller.
[0009] As a further improvement of this utility model: the locking rod is engaged with the slot, and the actuating locking block is engaged with the positioning lock hole.
[0010] As a further improvement of this utility model: an elastic rotating shaft is connected between the limiting pawl and the rotating bracket, and the limiting pawl is engaged with the ratchet gear.
[0011] As a further improvement of this utility model, a drive shaft is installed between the transmission roller and the drive mechanism.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] After disconnecting the limit pawl from the ratchet gear, the movable roller is rotated inside the rotating bracket to control the slot of the limit socket in another position to be adjusted to the position above the printing roll. This way, the dust removal purpose can be guaranteed without stopping the line.
[0014] By moving the toggle lock block outward, the limit of the toggle lock block and the positioning lock hole is broken. After removing and replacing the locking rod at the other end of the wiping brush from the slot, the dust removal mechanism can be continuously wiped clean inside. The wiping brush is easy to remove and install from the inside of the limit socket. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figure 1-4 As shown, this embodiment provides a dust removal device, including a printing support 1. The printing support 1 includes a support frame 2 and a dust removal mechanism body 5. The dust removal mechanism body 5 includes a rotating support 501 and a movable roller 502. Limiting sockets 503 are arrayed on the outer side wall of the movable roller 502. The limiting sockets 503 are fixedly connected to the movable roller 502. A slot 504 is opened above one end of the limiting socket 503. A toggle lock block 509 is connected to the end of the limiting socket 503 away from the slot 504 through an elastic rotating shaft. A wiping brush 505 is provided inside the limiting socket 503. The inner diameter of the limiting socket 503 is greater than the outer diameter of the wiping brush 505. A locking rod 510 is installed at one end of the wiping brush 505 corresponding to the position of the slot 504. The locking rod 510 is engaged with the slot 504. A positioning lock hole 508 is opened on the inner side of the other end of the wiping brush 505. The toggle lock block 509 is engaged with the positioning lock hole 508.
[0022] like Figure 2-3 As shown, in this embodiment, the movable roller 502 is mounted with a ratchet 506 on one side of the rotating bracket 501 via a rotating shaft. A limiting pawl 507 is mounted on the outer side of the ratchet 506 on the side surface of the rotating bracket 501. An elastic rotating shaft connects the limiting pawl 507 and the rotating bracket 501. The limiting pawl 507 engages with the ratchet 506. A transmission roller 3 is provided inside the support frame 2. A drive mechanism 4 is mounted on one end of the transmission roller 3 on the outer side of the support frame 2. A drive rotating shaft is installed between the transmission roller 3 and the drive mechanism 4. A printing roll 6 is provided on the inner side of the transmission roller 3.
[0023] The working principle of this utility model is as follows: In use, the main body 5 of the dust removal mechanism is placed above the transmission roller 3 and corresponding to the position of the printing roll 6. When the drive mechanism 4 drives the transmission roller 3 to rotate, the transmission roller 3 controls the conveying of the printing roll 6. The wiping brush 505 is used to wipe away the dust remaining on the surface of the printing roll 6. When the bristles of the wiping brush 505 wear out, the limiting pawl 507 can be moved outward to disengage the limiting pawl 507 from the ratchet 506. Then, the movable roller 502 is rotated inside the rotating bracket 501. The slot 504 of the limit socket 503 at another position is adjusted to the position above the printing roll 6. By moving the toggle lock block 509 at the end of the limit socket 503 where the worn wiping brush 505 is installed outward, the limit of the toggle lock block 509 and the positioning lock hole 508 is disengaged. The locking rod 510 at the other end of the wiping brush 505 is removed from the slot 504 and replaced. This ensures that the dust removal mechanism body 5 can continuously wipe dust inside, and the wiping brush 505 is easy to remove and install from the inside of the limit socket 503.
