Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to waste powder bin technical field, especially in one piece waste powder bin structure of forming. BACKGROUND
[0002] In the existing waste powder bin, there is a soft scraper in the waste powder bin, which is used to adhere to the drum core to clean the drum core. The existing soft scraper is installed on a metal knife holder, which is fixed on the waste powder bin by locking screws, and a sealing member such as sponge is also needed at the joint between the metal knife holder and the waste powder bin. The use of metal knife holder increases the production cost of waste powder bin, which needs to be further improved.
[0003] At the same time, during assembly, if the screws are not tightened or the seal is not properly attached, it may cause printing powder leakage and affect printing quality. INVENTION CONTENTS
[0004] The utility model aims at solving one of the technical problems in the prior art. To this end, the utility model provides a waste powder bin structure with a scraper holder and a waste powder bin formed integrally.
[0005] A waste powder bin structure formed integrally for this purpose, comprising a waste powder bin, the waste powder bin is connected with a scraper holder, the scraper holder and the waste powder bin are an integral forming structure, the scraper holder is connected with a soft scraper, and the soft scraper is attached to the drum core.
[0006] As a preferred, the waste powder bin is provided with a demolding opening on the outer wall surface corresponding to the scraper holder, and the demolding opening is provided with a sealing cover for closing the demolding opening.
[0007] As a preferred, the sealing cover is welded or glued and pasted to the waste powder bin.
[0008] As a preferred, the soft scraper is glued and fixed on the scraper holder.
[0009] As a preferred, the scraper holder is connected with a clamping plate, and the soft scraper is clamped between the clamping plate and the scraper holder.
[0010] Compared with the prior art, the scraper holder and the waste powder bin are designed as an integral forming structure, which can eliminate the use of metal knife holder and sealing member in the prior art, reduce the production cost of the part, and thus reduce the production cost. DRAWINGS

[0015] The utility model will be further described below in combination with the drawings and examples.
[0016] Referring to Figures 1-4 A waste powder bin structure of integral molding, including waste powder bin 10, the scraper seat 20 is connected to waste powder bin 10, the scraper seat 20 is the integral molding structure with waste powder bin 10, the soft scraper 30 is connected to the scraper seat 20, and the soft scraper 30 is attached to the drum core 40. In the embodiment, the scraper seat is designed as an integral molding structure with the waste powder bin, which can eliminate the use of the metal seat in the prior art, reduce the production cost of the part, and thus reduce the production cost.
[0017] Further, the scraper seat 20 and the waste powder bin 10 are integrally molded by injection molding.
[0018] Referring to Figure 3 The waste powder bin 10 is provided with a demolding port 110 on the outer wall surface corresponding to the scraper seat 20, and the demolding port 110 is provided with a sealing cover 50 for closing the demolding port 110. The function of the demolding port 110 is that, during injection molding, the mold core is inserted at the demolding port 110, so that the scraper seat 20 can be integrally injection molded with the waste powder bin 10. After completing injection molding, the mold core is demolded from the demolding port 110.
[0019] The design of the demolding port 110 makes the waste powder bin 10 incomplete, so the sealing cover 50 is designed to close the demolding port 110. In this embodiment, the sealing cover 50 is injection molded, which is simpler than producing a metal seat. The metal seat needs to be punched and bent to be formed. Therefore, by eliminating the metal seat and adding the sealing cover 50, the production cost is still reduced.
[0020] Further, the sealing cover 50 is welded and fixed to the waste powder bin 10.
[0021] Further, the soft scraper 30 is glued and fixed to the scraper seat 20.
[0022] Further, the scraper seat 20 is connected with a clamping plate, and the soft scraper 30 is clamped between the clamping plate and the scraper seat 20. The clamping plate can be welded and fixed to the scraper seat 20, and the clamping plate and the scraper seat 20 cooperate to clamp and fix the soft scraper 30.
