Description

Technical Field

[0001] The utility model relates to the technical field of selenium cartridges, in particular to an auxiliary device for facilitating the circulating powder filling of selenium cartridges. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are generally composed of a basic substrate made of aluminum and photosensitive materials coated on the substrate. In laser printers, more than 70% of the imaging components are concentrated in the toner cartridges. The quality of printing is actually largely determined by the toner cartridges. The toner cartridges not only determine the quality of printing, but also determine how much money the user needs to spend during use.

[0003] Toner cartridges need to be filled with toner powder during use, and the existing toner cartridge filling method is usually that the operator holds the toner cartridge in one hand and a container filled with toner powder in the other hand, and fills the toner powder in the container into the toner cartridge. Since there are usually four toner cartridges in a printer, the toner filling operation with the toner cartridge is inefficient, and it is impossible to fill multiple toner cartridges at one time. In addition, the container filled with toner powder is easily tipped over during the operation, resulting in leakage and waste of toner powder.

[0004] For this purpose, an auxiliary device is proposed to facilitate the circulation of toner filling of toner cartridges. Utility Model Content

[0005] The purpose of the utility model is to provide an auxiliary device for facilitating the circulation and filling of toner cartridges, so as to solve the problems raised in the above-mentioned background technology. To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary device for facilitating the circulation and filling of toner cartridges, comprising a top plate, a plurality of placement grooves are opened inside the top plate, a plurality of cavities are opened inside the top plate, a slide rod is movably installed inside the cavity, a rack is installed on one side of the slide rod, a gear is installed inside the cavity, the gear and the rack are connected by tooth meshing, a double-threaded screw is respectively installed inside the two sides of the placement groove, one end of the double-threaded screw is connected to one end of the gear, a slider is respectively provided on the outer side of the two ends of the double-threaded screw through a threaded meshing sleeve, a clamping plate is installed between the two sliders, and a supporting plate is installed at the bottom end of the slide rod.

[0006] Preferably, a bottom plate is installed between the two sliding rods, and a tension spring is installed on the top of the bottom plate.

[0007] Preferably, the top end of the tension spring is connected to the bottom end of the top plate.

[0008] Preferably, a rotating seat is installed at the bottom end of the top plate, and a supporting frame is installed at the bottom end of the rotating seat.

[0009] Preferably, a base is installed at the bottom end of the support frame, and a rubber anti-slip support pad is installed at the bottom of the base.

[0010] Preferably, there are four rubber anti-skid support pads, and the four rubber anti-skid support pads are respectively located at four corners of the bottom of the base.

[0011] Compared with the prior art, the utility model provides an auxiliary device for facilitating the circulation and filling of toner cartridges, and has the following beneficial effects:

[0012] By arranging a top plate, a placement slot, a slide bar, a rack, a bottom plate, a tension spring, a rack, a double-threaded screw, a gear and a clamping plate, multiple toner cartridges are placed in the placement slot in sequence. After the toner cartridge is placed in the placement slot, the bottom end of the toner cartridge will squeeze the supporting plate installed at the bottom end of the slide bar, and the slide bar can be pressed downward by relying on the weight of the toner cartridge, thereby driving the two clamping plates to slide relative to each other in the placement slot, clamping the two sides of the toner cartridge placed in the placement slot to ensure the stability of the toner cartridge when placed. When all the toner cartridges are placed in the placement slot, the operator only needs to fill the toner powder into the multiple toner cartridges in sequence. During the filling process, the operator does not need to hold the toner cartridges, but only needs to hold the container containing the toner powder, and the toner powder in multiple toner cartridges can be filled at one time to avoid the tipping over of the container containing the toner powder, which causes the waste of toner powder.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1: A plurality of placement grooves 9 are provided inside the top plate 8, a plurality of cavities 15 are provided inside the top plate 8, a slide rod 4 is movably installed inside the cavity 15, a rack 7 is installed on one side of the slide rod 4, a gear 14 is installed inside the cavity 15, the gear 14 and the rack 7 are connected by tooth meshing, a double-threaded screw rod 10 is respectively installed inside the two sides of the placement groove 9, one end of the double-threaded screw rod 10 is connected to one end of the gear 14, a slider 13 is respectively provided on the outer side of the two ends of the double-threaded screw rod 10 through a threaded meshing sleeve, a splint 12 is installed between the two sliders 13, a supporting plate is installed at the bottom end of the slide rod 4, and the top end of the tension spring 6 is connected to the bottom of the top plate 8.

[0021] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, since a plurality of placement slots 9 are provided inside the top plate 8, when multiple toner cartridges need to be filled with toner, the multiple toner cartridges can be placed in the placement slots 9 in sequence. After the toner cartridges are placed in the placement slots 9, the bottom end of the toner cartridge will squeeze the supporting plate installed at the bottom end of the slide bar 4. The slide bar 4 can be pressed downward by the weight of the toner cartridge, thereby pulling the tension spring 6 installed between the bottom plate 5 and the top plate 8. When the slide bar 4 slides downward, the rack 7 installed on one side of the slide bar 4 will drive the gear 14 to rotate. The rotation of the gear 14 can drive the double-threaded screw rod 10 to rotate. Since the outer sides of the two ends of the double-threaded screw rod 10 are respectively provided with a slider through a threaded engagement sleeve 13, and a clamping plate 12 is installed between the two sliders 13. Therefore, when the double-threaded screw 10 rotates, it will drive the two clamping plates 12 to slide relatively inside the placement slot 9, thereby clamping the two sides of the toner cartridge placed inside the placement slot 9 to ensure the stability of the toner cartridge when placed. When multiple toner cartridges are all placed inside the placement slot 9, the operator only needs to fill the toner powder into the multiple toner cartridges in turn. During the filling process, the operator does not need to hold the toner cartridge, but only needs to hold the container filled with toner powder. The toner powder in multiple toner cartridges can be filled at one time to avoid the container filled with toner powder from tipping over and causing waste of toner powder.

[0022] Embodiment 2: A bottom plate 5 is installed between the two sliding rods 4, a tension spring 6 is installed at the top of the bottom plate 5, a rotating seat 11 is installed at the bottom end of the top plate 8, and a support frame 3 is installed at the bottom end of the rotating seat 11, a base 1 is installed at the bottom end of the support frame 3, and a rubber anti-slip support pad 2 is installed at the bottom of the base 1, there are four rubber anti-slip support pads 2, and the four rubber anti-slip support pads 2 are respectively located at the four corners of the bottom of the base 1.

[0023] Specifically, Figure 1 and Figure 3 As shown, since the bottom of the top plate 8 is connected to the top of the support frame 3 through the rotating seat 11, the top plate 8 can be rotated on the top of the support frame 3 through the rotating seat 11, and the toner cartridges fixed in the slots 9 at different positions can be rotated in front of the operator through the rotation of the top plate 8, thereby avoiding the situation that the operator needs to move himself to fill the toner cartridge with toner after filling the toner cartridge with toner powder, thereby improving the speed of filling the toner cartridges with toner powder. Since four rubber anti-skid support pads 2 are installed at the bottom of the base 1, and the four rubber anti-skid support pads 2 are respectively located at the four corners of the bottom of the base 1, the stability of the entire device can be ensured by the support of the four rubber anti-skid support pads 2, and the device can be prevented from shaking or even tipping over during use.

[0024] Working principle: when in use, multiple toner cartridges can be placed in the placement slot 9 in sequence. After the toner cartridge is placed in the placement slot 9, the bottom end of the toner cartridge will squeeze the supporting plate installed at the bottom end of the slide rod 4. Relying on the weight of the toner cartridge, the slide rod 4 can be pressed downward, thereby pulling the tension spring 6 installed between the bottom plate 5 and the top plate 8. When the slide rod 4 slides downward, the rack 7 installed on one side of the slide rod 4 will drive the gear 14 to rotate, and the rotation of the gear 14 can drive the double-threaded screw rod 10 to rotate. Since the outer sides of the two ends of the double-threaded screw rod 10 are respectively provided with a slider 13 through a threaded engagement sleeve, and a clamping plate 12 is installed between the two sliders 13, when the double-threaded screw rod 10 rotates, it will drive the two clamping plates 12 to slide relative to each other in the placement slot 9, thereby clamping the two sides of the toner cartridge placed in the placement slot 9 to ensure the stability of the toner cartridge when it is placed. When multiple toner cartridges are all placed in the placement slot 9, the operator only needs to place the carbon powder in turn The toner cartridges can be filled into multiple toner cartridges. During the toner filling process, since the bottom of the top plate 8 is connected to the top of the support frame 3 through the rotating seat 11, the top plate 8 can be rotated on the top of the support frame 3 through the rotating seat 11. The toner cartridges fixed in the placement slots 9 at different positions can be rotated in front of the operator through the rotation of the top plate 8, avoiding the situation that the operator needs to move himself to fill the toner cartridge in another toner cartridge after the toner filling in the toner cartridge is completed, thereby improving the speed of filling the toner cartridges in multiple toner cartridges. After the filling is completed, it is only necessary to extract the toner cartridge in the placement slot 9 from the placement slot 9. When the toner cartridge is pulled out from the placement slot 9, the pulling force of the tension spring 6 disappears. The rebound of the tension spring 6 can drive the slide rod 4 to move upward, thereby driving the double-threaded screw rod 10 to rotate in the direction, so that the two clamping plates 12 leave the two sides of the toner cartridge, which is convenient for the operator to take the toner cartridge out of the placement slot 9.

[0025] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
