Description

Carbon powder expansion device and toner cartridge

Technical Field

The utility model relates to an imaging printing technology field, especially the technical field of laser printing required selenium drum.

Background

The laser printing apparatus can realize a 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. The toner cartridge is usually provided with an integrated toner storage container, i.e., a toner hopper (referred to as a "toner hopper" for short), for storing toner required for printing on the toner cartridge. However, the storage capacity of the toner hopper is limited, and the service life of the core component of the toner cartridge is long, so that the core component of the toner cartridge still has use value after the toner in the toner hopper is used up.

People adopt various technologies to prolong the service life of the selenium drum so as to fully utilize the use value of the core component of the selenium drum. Among the many technologies, the technology of expanding the capacity of the toner hopper is widely used. The main principle of this technology is to increase the capacity of the toner hopper to obtain a large-capacity toner hopper to contain more toner, thereby prolonging the service life of the toner cartridge.

Because the space for accommodating the toner cartridge of the laser printing device is limited and a space for allowing laser projected by the laser printing device to pass through needs to be reserved in the space, the layout of the large-capacity toner hopper is limited. In order to increase the volume of the carbon powder bin as much as possible, imaging laser passing gaps penetrating through the large-capacity carbon powder bin are arranged, so that the large-capacity carbon powder bin can fully utilize the space of the upper part and the lower part of the projected laser while meeting the requirement of laser projection, and the volume of the carbon powder bin is expanded. Although the volume of the toner powder bin is expanded, the toner powder bin is divided into two main bins because the imaging laser passing gap is hollowed out on the toner powder bin. The lower chamber is communicated with an imaging part of the toner cartridge to supply carbon powder for printing; the upper bin supplies the toner stored in the lower bin. However, the toner in the upper chamber is easy to accumulate, and the two main chambers are communicated only through a narrow passage. This condition makes the transfer of toner between the two main chambers non-smooth and therefore results in a large amount of toner that cannot be fully utilized.

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 shows an embodiment of the cartridge of the present invention. The utility model discloses a toner cartridge is provided with powder storehouse 106 and carbon dust flash chamber. The toner expansion device includes a toner container main bin 103, a toner container upright bin 101, and a toner container upright bin 105. The toner container upright bin 101 and the toner container upright bin 105 are disposed at the two ends of the toner container main bin 103 in the long axis direction, respectively. The toner container upright bin 101 and the toner container upright bin 105 are disposed to protrude from the toner container main bin 103. Powder bin connection ports (not shown) are provided on both the toner container column bin 101 and the toner container column bin 105. The toner container upright bin 101 and the toner container upright bin 105 are both in communication with the toner container main bin 103 through toner bin connection ports. As shown in FIG. 1, after the toner hopper 106 is connected to the toner hopper, a continuous imaging laser passing gap 107 is formed between the toner container upright bin 101 and the toner container upright bin 105, i.e., between the toner container main bin 103 and the toner hopper 106. Laser light projected by the laser printing apparatus may be projected onto the core member of the cartridge through the gap 107 by imaging laser light.

When the toner cartridge is assembled in the laser printing apparatus, the toner expansion device is located above the toner hopper 106 in the gravity direction, and the toner in the toner expansion device can be replenished into the toner hopper 106 and then is input to the imaging component of the toner cartridge by the toner hopper 106 for imaging. As can be seen in FIG. 1, the toner in the toner hopper is primarily dependent on gravity to drive the toner therein into the toner hopper 106. The carbon powder of the bottom that the formation of image laser passes through the carbon powder container main storehouse 103 of clearance 107 top is difficult for flowing, for solving this problem, the utility model discloses a carbon powder flash chamber is provided with the indent structure in this bottom. The concave structure is formed by a toner container main bin wall 102 and a toner container main bin wall 104 which are inclined towards the inside of the toner container main bin 103. The toner container main bin wall 102 and the toner container main bin wall 104 are respectively inclined from the toner container upright bin 101 and the toner container upright bin 105 to the middle of the toner container main bin 103. The concave structure thus constitutes a structure shaped like a pointed roof. The concave structure forms two slopes in the toner container main bin 103, the high point of the two slopes in the direction of gravity is in the middle of the toner container main bin 103, and the low point of the two slopes in the direction of gravity is at the toner container upright bin 101 and the toner container upright bin 105, respectively. Under the force of gravity, the toner in the main toner container bin 103 will more easily move along the ramp towards the toner container upright bin 101 and the toner container upright bin 105 to enter the toner bin 106 smoothly, preventing toner from building up locally in the main toner container bin 103 and failing to enter the toner bin 106.

As shown in fig. 2, the cartridge of the present invention is further provided with a waste powder expansion bin (not shown in the figure) communicated with the waste powder bin 201, so as to expand the volume of the waste powder bin 201. Due to the arrangement of the carbon powder expansion device, the amount of the carbon powder used by the toner cartridge is increased, and correspondingly, the amount of the waste powder generated in the imaging process is increased in proportion. The waste powder bin 201 with the expanded volume can contain more waste powder, and the waste powder leakage caused by insufficient volume of the waste powder bin 201 is avoided.

It should be noted that the above mentioned embodiments are only preferred embodiments of the present invention, and not intended to limit the scope of the present invention, and the present invention may be modified in materials and structures, or replaced by technical equivalents. Therefore, all the structural equivalents made by using the descriptions and drawings of the present invention, and all the applications in other related technical fields directly or indirectly are all within the scope of the present invention.
