Description

Technical Field

[0001] The invention belongs to the technical field of printers, and in particular relates to an adaptive waste paper recovery structure of a printer. Background Art

[0002] A printer is an electronic device used to convert data from a computer or other digital device into visible text or images, usually output on paper. Printers are one of the common office automation devices in offices and homes, used to print documents, reports, pictures, etc.

[0003] Printers are usually equipped with a waste paper recycling mechanism for recycling waste paper after printing. The existing waste paper recycling mechanism usually rewinds the waste paper by frictionally engaging friction discs rotating in opposite directions. After long-term use, the friction discs will wear out due to friction, resulting in unstable recycling. In addition, the frequent replacement of friction discs is cumbersome and not conducive to use. Summary of the invention

[0004] The object of the present invention is to provide an adaptive waste paper recovery structure of a printer to solve the problems raised in the above background technology.

[0005] In view of this, the present invention provides an adaptive waste paper recycling structure of a printer, comprising:

[0006] main body;

[0007] The recycling shaft has one end rotatably connected to the main body, and the interior of the recycling shaft is hollow to form an accommodating space. The recycling shaft reels the printed waste paper by rotating, and the interior of the recycling shaft is hollowed out, which is different from the existing solid design.

[0008] The recovery transmission mechanism is built into the accommodating space of the recovery shaft, and the recovery transmission mechanism can be driven to generate a rotational motion. The recovery transmission mechanism generates a torque to drive the recovery shaft to rotate to achieve the function of recycling waste paper. The recovery transmission mechanism replaces the design of the traditional friction disk, and the recovery transmission mechanism is hidden inside the recovery shaft, which not only simplifies the external structure, but also has a better protective effect to prevent damage from bumps.

[0009] The active transmission mechanism is rotatably arranged on the main body, and the active transmission mechanism generates an active driving force. The active transmission mechanism serves as a main driving force component of the receiving printer, thereby driving the rotation of the recovery transmission mechanism.

[0010] The part of the recovery transmission mechanism close to one end of the main body extends out of the recovery shaft, and the part is meshed with the active transmission mechanism for transmission connection, and receives the power of the active transmission mechanism to rotate. The recovery transmission mechanism can only make unidirectional rotation along the first direction, that is, the recovery transmission mechanism can only rotate in one direction and cannot rotate in the opposite direction, so as to ensure the normal recovery of waste paper without releasing paper. The other end of the recovery transmission mechanism away from the main body is connected to the recovery shaft through an elastic torsion force, so that when the recovery transmission mechanism rotates a certain angle along the first direction, the torque is released to the recovery shaft to drive the recovery shaft to rotate in the first direction. When the recovery transmission mechanism stops, the torque acts on the recovery shaft and stops when the torque is completely released. That is, when the recovery transmission mechanism rotates in the first direction, the elastic potential energy is stored. When it rotates to a certain angle until the elastic potential energy is sufficient to drive the recovery shaft to rotate, it drives the rotation after recovery. This driving method causes the recovery transmission mechanism and the recovery shaft to produce a relative movement with a speed difference, which is more convenient for the winding of waste paper. When the elastic potential energy is released to the point where the elastic tension and the paper tension are equal, the recovery shaft stops moving.

[0011] The anti-dislocation mechanism is an anti-dislocation ring, which is molded on the main body. An anti-dislocation groove is provided at the bottom end of the recovery shaft. The anti-dislocation ring is plugged into the anti-dislocation groove, so that when the recovery shaft rotates along the first direction, the anti-dislocation ring and the anti-dislocation groove slide together, thereby playing a radial anti-dislocation constraint on the recovery shaft, preventing the recovery shaft from shaking and falling off the main body.

[0012] A further embodiment of the present invention is that the recovery transmission mechanism is coaxially arranged with the recovery shaft and is located on the axis of the recovery shaft.

[0013] A further implementation scheme of the present invention is that a positioning boss is convexly formed on the main body, one end of the recovery shaft is inserted into the positioning boss, and the recovery shaft can rotate on the positioning boss, the recovery transmission mechanism passes through the positioning boss and extends into the interior of the recovery shaft, and the recovery shaft can rotate on the positioning boss.

[0014] A further implementation scheme of the present invention is that a positioning recess is also concavely formed on the main body, and an anti-slip ring is formed in the positioning recess. The positioning recess is located on both sides of the bottom of the positioning boss. A limiting boss is provided at one end of the recovery shaft. The limiting boss cooperates with the positioning recess to limit the recovery shaft, so that the recovery shaft always rotates along its axial direction on the positioning boss without separating from the positioning boss, thereby ensuring that the recovery shaft does not eccentrically shake when rotating, and the waste paper recovery is normally rolled up.

[0015] A further implementation scheme of the present invention is that a first cavity and a second cavity are formed inside the recovery shaft, the recovery shaft is limited by the first cavity and the positioning boss, the recovery shaft passes through the first cavity and the second cavity, and the other end of the recovery transmission mechanism is located in the second cavity and elastically cooperates with the recovery shaft.

[0016] A further embodiment of the present invention is that the active transmission mechanism comprises an active gear, and the active gear is rotatably arranged on the main body.

[0017] A further implementation scheme of the present invention is that the recovery transmission mechanism includes a recovery shaft, a driven gear and a one-way bearing, the one-way bearing is sleeved and fixed on one end of the recovery shaft, the one-way bearing is unidirectionally rotated in the driven gear, the driven gear and the driving gear are meshed for transmission, so that the driving gear drives the driven gear to rotate in a first direction. Since the one-way bearing can only allow one-way rotation in the first reverse direction, the recovery shaft can only be driven to rotate in the first direction.

[0018] A further implementation scheme of the present invention is that a sleeve is further provided on the outside of the recovery shaft, and the sleeve is inserted into the positioning boss. One end of the sleeve overlaps the end face of the positioning boss, and the other end abuts against the outer end face of the one-way bearing. The sleeve prevents the recovery shaft from wearing the positioning boss during rotation, thereby improving durability.

[0019] A further implementation scheme of the present invention is that a spring is sleeved on the part of the recovery shaft extending into the second cavity, and the outer side of the spring squeezes the inner wall of the second cavity. A shaft cover is fixed on the end of the recovery shaft, and the shaft cover presses the outer end of the spring. After the recovery shaft rotates in the first direction, it will drive the spring to twist. This process stores elastic potential energy. At this time, the recovery shaft is still in a stationary state. When the elastic potential energy of the spring is sufficient to drive the recovery shaft to rotate, the recovery shaft rotates in the first direction again. After the driving gear stops, the recovery shaft stops moving until the elastic potential energy of the spring is released to the point where the elastic tension is consistent with the paper tension. Therefore, during the recycling process, the recovery shaft and the recovery shaft produce a relative movement with a speed difference, and the recovery shaft is driven to recycle paper by the storage and release of elastic potential energy. The elastic potential energy is adapted to achieve automatic completion of paper recycling, and the recycling effect is ideal without the need for frequent replacement of parts.

[0029] Example 1

[0030] This embodiment provides an adaptive waste paper recycling structure of a printer, including:

[0031] Subject 1;

[0032] The recycling shaft 2 has one end rotatably connected to the main body 1, and the interior of the recycling shaft 2 is hollow to form an accommodating space. The recycling shaft 2 reels the printed waste paper by rotating, and the interior of the recycling shaft 2 is hollowed out, which is different from the existing solid design.

[0033] The recovery transmission mechanism 3 is built into the accommodating space of the recovery shaft 2, and the recovery transmission mechanism 3 can be driven to rotate. The recovery transmission mechanism 3 generates torque to drive the recovery shaft 2 to rotate to achieve the function of recycling waste paper. The recovery transmission mechanism 3 replaces the design of the traditional friction disk, and the recovery transmission mechanism 3 is hidden inside the recovery shaft 2, which not only simplifies the external structure, but also has a better protective effect to prevent damage from bumps.

[0034] The active transmission mechanism 4 is rotatably disposed on the main body 1 , and generates an active driving force. The active transmission mechanism 4 serves as a main driving force component of the receiving printer, thereby driving the rotation of the recovery transmission mechanism 3 .

[0035] The part of the recycling transmission mechanism 3 close to one end of the main body 1 extends out of the recycling shaft 2, and the part is meshed with the active transmission mechanism 4 for transmission connection, and receives the power of the active transmission mechanism 4 to generate rotation. The recycling transmission mechanism 3 can only make unidirectional rotation along the first direction A, that is, the recycling transmission mechanism 3 can only rotate in one direction and cannot rotate in the opposite direction, so as to ensure the normal recycling of waste paper without releasing paper. The other end of the recycling transmission mechanism 3 away from the main body 1 is connected to the recycling shaft 2 through an elastic torsion force, so that when the recycling transmission mechanism 3 rotates a certain angle along the first direction A, the torque is released. The force is applied to the recovery shaft 2 to drive the recovery shaft 2 to rotate in the first direction A. When the recovery transmission mechanism 3 stops, the torque is released and the recovery shaft 2 stops. That is, when the recovery transmission mechanism 3 rotates in the first direction A, it will store elastic potential energy. When it rotates to a certain angle until the elastic potential energy is sufficient to drive the recovery shaft 2 to rotate, it will drive the rotation after recovery. This driving method will cause the recovery transmission mechanism 3 and the recovery shaft 2 to produce a relative movement with a speed difference, which is more convenient for winding up the waste paper. When the elastic potential energy is released to the point where the elastic tension and the paper tension are equal, the recovery shaft 2 stops moving.

[0036] The anti-dislocation mechanism is an anti-dislocation ring 1C, which is molded on the main body 1. An anti-dislocation groove 2D is provided at the bottom end of the recovery shaft 2. The anti-dislocation ring 1C is plugged into the anti-dislocation groove 2D, so that when the recovery shaft 2 rotates along the first direction A, the anti-dislocation ring 1C and the anti-dislocation groove 2D slide together, thereby playing a radial anti-dislocation constraint on the recovery shaft 2, preventing the recovery shaft 2 from shaking and falling off the main body 1.

The recycling transmission mechanism 3 can only make unidirectional rotation along the first direction A, that is, the recycling transmission mechanism 3 can only rotate in one direction and cannot rotate in the opposite direction, so as to ensure the normal recycling of waste paper without releasing paper. The other end of the recycling transmission mechanism 3 away from the main body 1 is connected to the recycling shaft 2 through an elastic torsion force, so that when the recycling transmission mechanism 3 rotates a certain angle along the first direction A, the torque is released. The force is applied to the recovery shaft 2 to drive the recovery shaft 2 to rotate in the first direction A. When the recovery transmission mechanism 3 stops, the torque is released and the recovery shaft 2 stops. That is, when the recovery transmission mechanism 3 rotates in the first direction A, it will store elastic potential energy. When it rotates to a certain angle until the elastic potential energy is sufficient to drive the recovery shaft 2 to rotate, it will drive the rotation after recovery. This driving method will cause the recovery transmission mechanism 3 and the recovery shaft 2 to produce a relative movement with a speed difference, which is more convenient for winding up the waste paper.

[0059] In this embodiment, a positioning boss 1A is convexly formed on the main body 1, one end of the recovery shaft 2 is inserted into the positioning boss 1A, and the recovery shaft 2 can rotate on the positioning boss 1A. The recovery transmission mechanism 3 passes through the positioning boss 1A and extends into the interior of the recovery shaft 2, and the recovery shaft 2 can rotate on the positioning boss 1A.

[0060] A further implementation scheme of the present invention is that a positioning recess 1B is also concavely formed on the main body 1, and an anti-slip ring 1C is formed in the positioning recess 1B. The positioning recess 1B is located on both sides of the bottom of the positioning boss 1A. A limiting boss 2A is provided at one end of the recovery shaft 2.

The recovery shaft 2 passes through the first cavity 2B and the second cavity 2C, and the other end of the recovery transmission mechanism 3 is located in the second cavity 2C and elastically cooperates with the recovery shaft 2.

[0062] In this embodiment, the active transmission mechanism 4 includes an active gear 4A, and the active gear 4A is rotatably disposed on the main body 1 .

[0063] A further implementation scheme of the present invention is that the recovery transmission mechanism 3 includes a recovery shaft 3A, a driven gear 3B and a one-way bearing 3C, the one-way bearing 3C is sleeved and fixed on one end of the recovery shaft 3A, the one-way bearing 3C is unidirectionally rotatably arranged in the driven gear 3B, the driven gear 3B and the driving gear 4A are meshed for transmission, so that the driving gear 4A drives the driven gear 3B to rotate along the first direction A, and since the one-way bearing 3C can only allow one-way rotation in the first reverse direction, the recovery shaft 3A can only be driven to rotate along the first direction A.

[0064] Example 4

[0065] In this embodiment, based on the embodiment 3, a sleeve 3D is further provided on the outside of the recovery shaft 3A. The sleeve 3D is inserted into the positioning boss 1A. One end of the sleeve 3D overlaps the end face of the positioning boss 1A, and the other end abuts against the outer end face of the one-way bearing 3C. The sleeve 3D prevents the recovery shaft 3A from wearing the positioning boss 1A during rotation, thereby improving durability.

[0066] A further implementation scheme of the present invention is that a spring 3E is sleeved on the part of the recovery shaft 3A extending into the interior of the second cavity 2C, and the outer side of the spring 3E squeezes the inner wall of the second cavity 2C. A shaft cover 3F is fixed on the end of the recovery shaft 3A, and the shaft cover 3F presses the outer end of the spring 3E. After the recovery shaft 3A rotates along the first direction A, it will drive the spring 3E to twist. This process stores elastic potential energy. At this time, the recovery shaft 2 is still in a stationary state. When the elastic potential energy of the spring 3E is sufficient to drive the recovery shaft 2 to rotate, the recovery shaft 2 rotates along the first direction A again. After the driving gear 4A stops, the recovery shaft 2 stops moving until the elastic potential energy of the spring 3E is released to the point where the elastic tension is consistent with the paper tension. Therefore, during the recycling process, the recovery shaft 3A and the recovery shaft 2 produce a relative movement with a speed difference, and the recovery shaft 2 is driven to recycle paper by storing and releasing the elastic potential energy, and the elastic potential energy is adapted to realize the automatic completion of paper recycling. The recycling effect is ideal, and there is no need to frequently replace parts.
