Description

Laser printing selenium drum

Technical Field

The utility model relates to a laser printing technical field, especially the selenium drum technical field that laser printing equipment used.

Background

The laser printing device can realize the printing function only by consuming a developer such as carbon powder. During printing, toner needs to be transported from the toner storage container to the core of the cartridge. Toner cartridges are typically provided with an integral toner storage container, a toner hopper, for storing toner required by the cartridge. However, the storage capacity of the powder bin is limited, and the service life of the core component of the cartridge is long, so that the core component of the cartridge still has use value after the carbon powder in the powder bin is used up.

In order to avoid wasting the use value of the core component of the toner cartridge, a carbon powder supplementing technology for supplementing carbon powder to the toner cartridge is designed. Namely, after the carbon powder in the powder bin carried by the toner cartridge is consumed, the carbon powder can be supplemented into the powder bin by using the carbon powder supplementing device, so that the toner cartridge can be continuously used. The first one is that carbon powder is directly injected into the powder bin through a carbon powder supplementing opening on the toner hopper of the toner cartridge by using a carbon powder supplementing device during the stop of the toner cartridge; the carbon powder supplementing device of the second mode can be communicated with the toner cartridge when the toner cartridge works and can supplement carbon powder to the powder bin of the toner cartridge at any time. The two carbon powder replenishing modes have respective advantages and disadvantages. The first carbon powder supplementing mode only needs to utilize a common carbon powder bottle, has simple structure and low cost, but is easy to pollute the environment; the second carbon powder supplementing mode has simple operation and little environmental pollution, but has complex structure and relatively higher cost because of needing a specially designed carbon powder supplementing device.

The first toner replenishing method is to fill toner into the toner hopper through a toner replenishing port provided at an end of the toner cartridge in the longitudinal direction. In the operation process, the toner cartridge is erected, then the carbon powder supplementing opening at the end part of the toner cartridge is opened, and then the carbon powder is injected into the carbon powder supplementing opening. The carbon powder can smoothly enter the powder bin along the long axis direction of the toner cartridge under the action of gravity and fill the powder bin. The second carbon powder replenishing mode needs to be connected with the carbon powder replenishing device when the toner cartridge works, so that carbon powder is replenished into the powder bin at any time, and the powder bin does not need to be filled with carbon powder at one time. Therefore, the toner cartridge satisfying the second toner replenishing mode can only be provided with the toner replenishing port on the exposed surface when the toner cartridge works, and the direction of the replenished toner entering the toner bin is basically vertical to the long axis direction of the toner cartridge. The surface exposed when the cartridge works does not usually include the end part of the cartridge in the long axis direction. If the first toner supply method supplies toner through the toner supply opening formed on the exposed surface of the toner cartridge during operation, the toner cartridge is difficult to be smoothly filled with toner, and a large amount of toner is likely to overflow during operation.

The existing toner cartridge is often provided with a toner replenishing port, so that an operator cannot select a toner replenishing mode, and inconvenience in use is brought.

Detailed Description

The technical solution of the present invention will be described in detail below with reference to the embodiments shown in the drawings.

Fig. 1 to fig. 3 show the specific structure of an embodiment of the present invention from different angles, respectively. The utility model discloses a laser printing selenium drum (hereinafter be referred to as selenium drum for short) includes sensitization drum 301 and powder storehouse 101. The photosensitive drum 301 is a core component of the toner cartridge, and when the toner cartridge is assembled into the laser printing apparatus, imaging laser light emitted from a light source of the laser printing apparatus is projected onto the photosensitive drum 301 through the upper side of the toner hopper 101. A developing roller 204 is provided in parallel with the photosensitive drum 301. The long axis of the toner cartridge is parallel to the axis of the photosensitive drum 301, the internal space of the powder hopper 101 is also a long-strip-shaped space, and the long axis of the powder hopper 101 is parallel to the long axis of the toner cartridge. A first toner supply port 203 communicating with the toner hopper 101 is provided on the surface of the end of the toner cartridge in the longitudinal direction, and a reusable first cap 103 is provided on the first toner supply port 203. The first cap 103 may tightly close the first toner replenishment port 203.

The cartridge is divided into two end portions in the long axis direction in appearance, and a cartridge main body portion between the two end portions. When the toner cartridge is assembled into the laser printing equipment from the toner cartridge assembly port of the laser printing equipment, the surface of the toner cartridge main body part facing the toner cartridge assembly port is a toner cartridge exposed surface. The toner replenishing channel 202 protruding out of the toner cartridge exposed surface is arranged on the toner cartridge exposed surface. A second toner replenishing port 201 communicated with the toner hopper 101 is arranged at the end part of the original toner cartridge exposed surface of the toner replenishing channel 202. A reusable second cap 102 is provided over the second toner replenishment port 201. The second cap 102 may hermetically seal the second toner refill port 201. The carbon powder supplementing channel 202 can be matched with a corresponding interface of the carbon powder supplementing device to form a closed channel for the flow of supplemented carbon powder, so that the leakage of the carbon powder is avoided.

In this embodiment, the diameter of the circular first toner supply port 203 is the same as the diameter of the circular second toner supply port 201, and the diameter of the corresponding first cap 103 is the same as the diameter of the second cap 102. Therefore, the first sealing cover 103 and the second sealing cover 102 can be used interchangeably, and an operator does not need to carefully distinguish the toner replenishing port corresponding to the sealing cover, so that the operation efficiency is improved. In addition, in other embodiments, a cap receiving structure (not shown) may be provided on the surface of the cartridge body portion. The seal cover accommodating structure is a blind hole matched with the caliber of the seal cover, and the seal cover can be inserted into the blind hole. When replenishing the carbon powder, the sealing cover needs to be opened; the cover is required to be covered again when the carbon powder is supplemented. The seal cover accommodating structure enables an operator to have a convenient temporary storage position for the temporarily taken-off seal cover so as to prevent the seal cover from being lost and damaged due to random placement. The diameters of the first cover 103 and the second cover 102 are the same, so that only one cover accommodating structure is provided to meet the requirement of inserting the first cover 103 and the second cover 102.
