Description

Technical Field

[0001] The utility model relates to the field of image forming equipment, in particular to a developer supplying device. Background Art

[0002] Existing image forming devices use carbon powder particles as developer. When the developer particles in the container are consumed, a developer replenishing container needs to be used to replenish the developer for the image forming device.

[0003] The developer replenishing container in the prior art rotates in coordination with the image forming device, and the valve member at the filling end of the image forming device is restricted in movement by a limiting member, resulting in the user being unable to directly open the valve member at the machine end. The limiting member needs to be rotated a certain angle and then raised before the restriction of the valve member can be released.

[0004] Therefore, when the developer replenishing container is mounted in the image forming apparatus, a structure for releasing the restriction of the shutter member is required. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, the purpose of the utility model is to provide a developer supply device to solve the above-mentioned technical problems.

[0006] In order to achieve the purpose, the utility model adopts the following technical solutions:

[0007] A developer supply device is detachably mounted on a mounting portion of an image forming device to supply developer to the image forming device. The mounting portion is provided with a rotation limiting mechanism, a valve member and a powder inlet. The valve member is provided with a middle hole. After the valve member rotates on the mounting portion, the middle hole can be connected with the powder inlet. The rotation limiting mechanism can limit the rotation of the valve member. The developer supply device comprises:

[0008] a receiving portion capable of receiving a developer;

[0009] a discharge base connected to the accommodating portion and having a discharge port for discharging the developer; and

[0010] The release part includes a driving member and a bending angle. The bending angle can change the movement direction of the driving member. When the developer supply device is installed in the installation part, the driving member changes the movement direction through the bending angle so as to abut against the rotation limiting mechanism, thereby driving the rotation limiting mechanism to release the restriction on the valve component.

[0011] The developer supply device of the utility model is provided with a release part. When the developer supply container is downwardly mounted to the mounting part of the image forming device, the release part can release the restriction of the shutter component of the image forming device by the rotation restriction mechanism.

[0012] In some embodiments, the release portion also includes a supporting member, which is mounted on the driving member and can move relative to the driving member closer to or away from the discharge base, and a bending angle is set on the supporting member; when the developer replenishing device is installed on the mounting portion, the supporting member is acted upon by the mounting portion to move toward the discharge base, the driving member moves in the supporting member and changes the direction of movement through the bending angle, and the driving member at least partially extends out of the supporting member, thereby abutting against the rotation limiting mechanism.

[0013] In some embodiments, one end of the driving member extending out of the bending angle is the driving end, and the bending angle is configured to extend the driving end of the driving member toward the circumferential direction of the discharge base and in the direction of movement opposite to the installation direction of the developer supplying device, abut against the rotation limiting mechanism and drive the release component of the rotation limiting mechanism to rotate and move opposite to the installation direction of the developer supplying device, thereby releasing the restriction on the valve component.

[0014] In some embodiments, the release portion further includes an elastic member, and the elastic member is used to provide an elastic force for the support member to move away from the discharge base.

[0015] In some embodiments, the elastic member is sleeved on the driving member, and two ends of the elastic member are respectively in contact with the discharge base and the supporting member.

[0016] In some embodiments, the driving member includes a connecting end connected to the discharge base and a driving end that passes through the support member and extends out of the support member for driving the rotation limiting mechanism, and the driving end of the driving member is provided with a limit block that can limit the movement of the driving member into the support member.

[0017] In some embodiments, the rotation limiting mechanism includes a limiting member that limits the valve member and a releasing member that releases the restriction of the valve member by the limiting member, and the releasing member is provided with a driven surface that is oblique to the installation direction of the developer replenishing device. When the developer replenishing device is installed on the installation portion, the driving member can change the movement direction toward the driven surface by a bending angle, and the driving member can abut against the driven surface and drive the releasing member to rotate and move back to the installation direction of the developer replenishing device, so that the releasing member drives the limiting member to release the restriction on the valve member.

[0018] In some embodiments, the release portion is disposed at an end of the discharge base away from the receiving portion.

[0019] In some embodiments, the developer supply device further comprises a rotating member mounted on the discharge base and rotatable relative to the discharge base. When the developer supply device is mounted on the mounting portion, the rotating member engages with the valve member, and the rotating member can drive the valve member to rotate on the image forming device to connect the middle hole with the powder inlet.

[0020] The rotating member is configured to be driven to rotate by an operating lever on a mounting portion of the image forming device, thereby driving the shutter member to rotate.

[0021] In some embodiments, the discharge base is further provided with a guide portion that can be extended and retracted along the axial direction of the discharge base. The guide portion is located on one side of the release portion in the circumferential direction of the discharge base. The guide portion can move relative to the discharge base together with the support member to support and guide the support member.

[0022] In some embodiments, two releasing portions are provided, and the two releasing portions are axially symmetrically arranged at one end of the discharge base away from the accommodating portion. BRIEF DESCRIPTION OF THE DRAWINGS

In this case, when using the image forming apparatus 100, it may be difficult for the user to mount the developer supply device 200 on the mounting portion 110. Therefore, the image forming apparatus 100 of this embodiment is provided with a rotation limiting mechanism 170 to prevent the shutter member 130 from rotating from the closed position to the open position.

At this time, the position of the restricting member 171 is the restricting position.

[0071] See also Fig.18 , Fig. 20 As shown, in the rotation direction of the shutter member 130, a release spring (not shown) is provided between the limiting member 171 and the release member 172, one end and the other end of the release spring are respectively engaged with the first spring engagement portion 171g of the limiting member 171 and the second spring engagement portion 172g of the release member 172, and the limiting member 171 receives a moment M1 in the rotation direction D by the urging force F2 of the release spring toward the rotation direction D, and the second convex portion 172a on the release member 172 extends into the third concave portion 160b, so that the third concave portion 160b of the cover 160 limits the rotation of the release member 172 in the rotation direction D. On the other hand, the release member 172 receives a moment M2 in the rotation direction E generated by the urging force F3 of the release spring, and the first convex portion 171b of the limiting member 171 is caught in the second concave portion 160a of the cover 160, so that the limiting member 171 is limited in rotation in the rotation direction E.

[0072] See also Fig.10 , Fig. 20 As shown, a restricted rib 130c is provided on the valve member 130, and the restricted rib 130c is a rib radially protruding on the inner side of the valve member 130. In the initial state, that is, when the limiting member 171, the releasing member 172 and the cover 160 are all arranged inside the valve member 130, the restricted rib 130c can fall into the gap G formed by the first limiting surface 160c1 of the cover 160 and the second limiting surface 171c1 of the limiting member 171. Therefore, the restricted rib 130c of the valve member 130 is located between the first limiting surface 160c1 of the cover 160 and the second limiting surface 171c1 of the limiting member 171, and the rotation of the valve member 130 along the rotation direction D (the direction from the closed position to the open position) is restricted by the second limiting surface 171c of the limiting member 171, and the rotation of the valve member 130 along the rotation direction E (the direction from the open position to the closed position) is restricted by the first limiting surface 160c1 of the cover 160.

[0073] When it is necessary to release the restriction of the valve member 130, after moving the restriction member 171 along the axial direction of the valve member 130, the second restriction surface 171c1 set by the restriction member 171 no longer restricts the valve member 130 in the rotation direction D, and the valve member 130 can be rotated to connect the middle hole 131 and the powder inlet 150, so that the developer in the developer supply device 200 can be replenished to the image forming device 100. Specifically, the third recess 160b is a second-step recess on the cover 160, and when the limiting member 171 is installed in the cover 160, the first recess 171c of the limiting member 171 overlaps with the first-step recess 160b1 of the third recess 160b in the axial direction of the valve member. In the initial state, when the second convex portion 172a of the releasing member 172 extends into the first recess 171c and the third recess 160b and moves in the rotation direction D, the second convex portion 172a abuts against the first-step recess 160b1 of the third recess 160b and the first recess 171c; when released, the second convex portion 172a of the releasing member 172 moves along the rotation direction D, the second convex portion 172a moves into the second-step recess 160b2 of the third recess 160b, and the second convex portion 172a of the releasing member 172 moves along the axial direction of the valve member 130 (backwards from the installation direction M of the developer replenishing device), and the second convex portion 172a of the releasing member 172 Part 172a drives the limiting member 171 to move in the second-order recess 160b2 of the third recess 160b along the axial direction of the valve member 130 (backwards from the installation direction M of the developer replenishing device) until the first recess 171c of the limiting member 171 moves along the axial direction to the recessed surface of the second-order recess 160b2 of the third recess 160b. At this time, the second limiting surface 171c1 of the first recess 171c does not overlap with the restricted rib 130c in the axial direction of the valve member 130, that is, the first recess 171c moves to a position that does not hinder the restricted rib 130c, and the second limiting surface 171c1 of the first recess 171c no longer restricts the valve member 130 in the rotation direction D. The valve member 130 can rotate along the rotation direction D, so that the valve member 130 can rotate to the position corresponding to the middle hole 131 and the middle cavity 1211, and the middle hole 131 is connected to the powder inlet 150.

[0077] See also Fig.23As shown, the release part 230 is arranged at one end of the discharge base 220 away from the accommodating part 210, and the release part 230 includes an elastic member 231, a supporting member 232 and a driving member 233. The supporting member 232 is sleeved on the driving member 233 and can move closer to or away from the discharge base 220 relative to the driving member 233, that is, the supporting member 232 is mounted on the end of the discharge base 210 away from the accommodating part 210 by being sleeved on the driving member 233. The driving member 233 is provided with a connecting end 233a connected to the discharge base 210 and a driving end 233b that passes through the supporting member 232 and extends out of the supporting member 232 for driving the rotation limiting mechanism 170, and the supporting member 232 An elastic member 231 is also provided between the discharge base 220, and the elastic member 231 is respectively in contact with the discharge base 220 and the support member 232. When the support member 232 is squeezed, it can overcome the elastic force of the elastic member 231 and approach the discharge base 220, so that the driving member 233 moves in the support member 232, and the driving end 233b of the driving member 233 continues to extend from the support member 232, and is used to drive the release member 172 in the mounting portion 110 to rotate and move when the developer replenishing device 200 is installed in the mounting portion 110, so that the valve member 130 is not restricted and the valve member 130 can rotate to connect the middle hole 131 with the powder inlet 150. Preferably, the driving member 233 is made of a deformable metal material, the supporting member 232 is a hollow member provided with a channel, the supporting member 232 and the driving member 233 are a pair of guide sleeves and hairsprings, specifically, the outer diameter of the guide sleeve is 1.0 mm, the inner diameter is 0.6 mm, and the wall thickness is 0.2 mm. The material can be stainless steel, or a PET or PA tube, and the guide wire can be a 0.5 mm metal soft shaft, or a nylon wire, such as the nylon wire used for fishing. One end of the guide wire (i.e., the connecting end) is connected to the end of the discharge base away from the accommodating portion, and the other end (i.e., the driving end) passes through the guide sleeve. The elastic member 231 is a spring, which is arranged between the guide sleeve and the discharge base. The developer supply device 200 is installed toward When the developer replenishing device 200 is installed in the mounting portion 110, the supporting member 232 is squeezed by the mounting portion 110, and the supporting member 232 moves toward the position close to the discharge base 220 (i.e., moves in the opposite direction relative to the mounting direction M). The driving member 233 abuts against the releasing member 172 at the end of the supporting member 232, and as the developer replenishing device 200 continues to be installed, the releasing member 172 is pushed to rotate and move. After the releasing member 172 rotates and moves, it can drive the limiting member 171 to move along the axial direction of the valve member 130. The limiting member 171 no longer limits the rotation of the valve member 130. The valve member 130 is released from the restriction and can rotate in the mounting portion 110 until the middle hole 131 is connected to the powder inlet 150.

[0078] Furthermore, the discharge base 220 is also provided with a retractable guide portion 234, which is arranged on one side of the support member 232 and can limit the movement of the support member 232. Specifically, in the present embodiment, the discharge base 220 is provided with a guide portion 234 at one end away from the accommodating portion 210, and the guide portion 234 can be retracted along the axial direction of the discharge base 220 on the discharge base 220, and the guide portion 234 is located on one side of the release portion 230 in the circumferential direction of the discharge base 220. Preferably, the guide portion 234 can be glued or welded to the support member 232 in the release portion 230, and when the support member 232 is away from or close to the discharge base 220, the support member 232 can move together with the guide portion 234, so that the support member 232 will not move crookedly, and the driving member 233 can correctly drive the release member 172 to rotate.

[0079] The support member 232 is also provided with a bending angle 232a, and the driving member 233 can move at the position of the bending angle 232a of the support member 232, so that the driving member 233 can change the movement direction through the support member 232, and is used to drive the release member 172 to rotate and move.

When the developer supply device 200 is installed on the installation portion 110, the driving end 233b of the driving member 233 can change the movement direction toward the driven surface 172e1 through the bending angle 232a of the supporting member 232. As the developer supply device 200 is installed, the driving member 233 extends out of the supporting member 232. The holding member 232 is in contact with the driven surface 172e1, and the developer supplying device 200 continues to be installed, so that the driving end 233b of the driving member 233 can be changed to drive the releasing member 172 to rotate and move back to the installation direction M of the developer supplying device 200. The releasing member 172 drives the limiting member 171 to move back to the installation direction of the developer supplying device 200, so that the valve member 130 is no longer restricted by the limiting member 171, and can rotate on the mounting portion 110, connecting the middle hole 131 and the powder inlet 150.

Specifically, in this embodiment, the limit block 2331 is a cylindrical block structure provided on the end of the driving member 233, and its diameter is larger than the diameter of the supporting member 232, so that the driving end 233b of the driving member 233 will not be received into the supporting member 232, thereby preventing the supporting member 232 on the developer supply device 200 from being separated or lost.

[0081] Furthermore, two releasing claws 172 e are provided on the releasing member 172 , so two releasing portions 230 are provided on the discharge base 220 , and the two releasing portions 230 are axially symmetrically arranged at one end of the discharge base 220 away from the accommodating portion 210 .
