Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing consumable equipment technology, and in particular to a stacked cup telescopic device for powder dispensing from a powder cylinder. Background Technology
[0002] Printer toner cartridges are an essential component of printers. Their main function is to store toner for printing and distribute it evenly to the print head during the printing process. Conventional toner cartridges are prone to leakage and toner buildup during use, resulting in wasted toner, contamination of the printer's working environment, and potential damage to the equipment. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model proposes a stacked cup telescopic device for powder dispensing from a powder cylinder. It aims to solve the problems of powder jamming and powder accumulation during the powder dispensing process.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a stacked cup-type telescopic device for discharging powder from a powder cylinder, comprising a cylinder body and a head cover disposed at the powder outlet of the cylinder body, a connecting frame disposed on the head cover, and a limiting block disposed at the end of the connecting frame, characterized in that a telescopic leakage-preventing device is sleeved around the connecting frame, one end of the telescopic leakage-preventing device is fixedly installed with the head cover, the telescopic leakage-preventing device comprises a first sleeve, a second sleeve, and a return spring sleeved around the second sleeve, the first sleeve and the second sleeve are slidably fitted, and a spring limiting cover is disposed at the upper end of the second sleeve, the spring limiting cover having a chamfered groove inside.
[0005] Based on the above, when the telescopic leak-proof device is not compressed, the top surface of the spring limiting cover located at the upper end of the second sleeve mates with the bottom surface of the limiting block, forming a sealed space inside the toner cartridge to prevent toner leakage. During toner feeding, the second sleeve overlaps with the first sleeve under the push of an external force, causing the telescopic leak-proof device to be in a compressed state. The toner is then fed through the channel formed between the telescopic leak-proof device and the connecting column. Because the second sleeve has a straight inner wall and a chamfered groove is provided inside the spring limiting cover, the toner feeding process is smoother, preventing toner jamming and accumulation, thus improving toner utilization.
[0006] Furthermore, a limiting ring is provided at the lower end of the first sleeve, and the bottom surface of the limiting ring is provided with an inclined surface that tilts towards the center.
[0007] Based on the above, the bottom surface of the limiting ring is provided with an inclined surface that tilts towards the center, which can clean the carbon powder attached to the inner wall of the sleeve one during the compression and movement of the second sleeve, thereby reducing the waste of carbon powder.
[0008] Furthermore, a sealing ring is fitted at the mating connection between the first sleeve and the second sleeve.
[0009] Based on the above, the sealing ring can make the fit between the first sleeve and the second sleeve tighter, preventing powder leakage.
[0010] Furthermore, a retaining ring is provided on the mating plane between the first sleeve and the head cover. The retaining ring is located inside the first sleeve. When the second sleeve is compressed to its limit position, the retaining ring contacts the bottom of the limiting ring and limits the second sleeve.
[0011] Based on the above, the bottom of the limiting ring cooperates with the retaining ring to limit the movement of the second sleeve.
[0012] Furthermore, the head cover is also fitted with a screw cap via a threaded connection.
[0013] Based on the above, the screw cap is used to cover the cavity of the head cover, so that the toner cartridge is sealed when not in use and there will be no toner leakage. Before the toner cartridge is connected to the printer for use, the screw cap needs to be removed.
[0014] Furthermore, the second sleeve and the spring limiting cover are engaged by threads.
[0015] Based on the above, the second sleeve and the spring limiting cover are connected by a thread, which facilitates the installation of the reset spring.
[0016] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0021] like Figures 1 to 3As shown, a stacked cup-type telescopic device for discharging powder from a powder cartridge includes a cartridge body 1 and a head cover 2 disposed at the powder outlet of the cartridge body 1. A connecting frame 3 is disposed on the head cover 2, and a limiting block 4 is disposed at the end of the connecting frame 3. A telescopic leakage-preventing device 5 is sleeved around the connecting frame 3, and one end of the telescopic leakage-preventing device 5 is fixedly installed to the head cover 2. The telescopic leakage-preventing device 5 includes a first sleeve 6, a second sleeve 7, and a return spring 8 sleeved around the second sleeve 7. The first sleeve 6 and the second sleeve 7 are slidably engaged. A spring limiting cover 9 is disposed at the upper end of the second sleeve 7, and a chamfered groove 10 is disposed inside the spring limiting cover 9. When the telescopic leakage-preventing device 5 is not compressed, the top surface of the spring limiting cover 9 disposed at the upper end of the second sleeve 7 engages with the bottom surface of the limiting block 4, forming a sealed space inside the powder cartridge to prevent powder leakage. During toner feeding, the second sleeve 7 overlaps with the first sleeve 6 under external force, compressing the telescopic leak-proof device 5. The toner is then fed through the channel formed between the telescopic leak-proof device 5 and the connecting column. Because the second sleeve 7 has a straight inner wall and a chamfered groove 10 is provided inside the spring limiting cover 9, the toner feeding process is smoother, preventing toner jamming and accumulation, thus improving toner utilization.
[0022] Preferably, the lower end of the first sleeve 6 is provided with a limiting ring 11, and the bottom surface of the limiting ring 11 is provided with an inclined surface 12 that is inclined towards the center, so that the second sleeve 7 can clean the carbon powder attached to the inner wall of the first sleeve 6 during the compression and movement process.
[0023] Preferably, a sealing ring 13 is fitted at the mating connection between the first sleeve 6 and the second sleeve 7. The sealing ring 13 enables a tighter fit between the first sleeve 6 and the second sleeve 7, preventing powder leakage.
[0024] Preferably, a retaining ring 14 is provided on the mating plane between the first sleeve 6 and the head cover 2. The retaining ring 14 is disposed inside the first sleeve 6. When the second sleeve 7 is compressed to the limit position, the retaining ring 14 contacts the bottom of the limiting ring 11 and limits the second sleeve 7.
[0025] Preferably, the head cover 2 is also fitted with a screw cap 15 via a threaded connection. The screw cap 15 is used to cover the cavity of the head cover 2, so that the toner cartridge is sealed when not in use and to prevent toner leakage. Before the toner cartridge is connected to the printer for use, the screw cap 15 needs to be removed.
[0026] Preferably, the sleeve 7 and the spring limiting cover 9 are threaded together to facilitate the installation of the reset spring 8.
[0027] The specific implementation of this embodiment is as follows: When using the toner cartridge, the head cover 2 is installed in conjunction with the printing equipment. The toner cartridge is installed on the printing equipment, which is equipped with a pushing module that pushes the spring-limiting cover 9. This pushing module pushes the spring-limiting cover 9, moving the sleeve 7 along with it, so that the sleeve 6 overlaps with the sleeve 7. The toner is then delivered through the channel formed between the telescopic leakage-preventing device 5 and the connecting post. During the process of pulling out the toner cartridge, the return spring 8 will cause the sleeve 7 to return to its original position, ensuring a tight fit between the top surface of the spring-limiting cover 9 and the bottom surface of the limiting block 4, preventing toner leakage.
[0028] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
