Description

TECHNICAL FIELD

[0001] The utility model relates to printing consumables processing box technical field, concretely relates to a stirring frame, stirring assembly and processing box. BACKGROUND

[0002] The existing processing box includes a stirring assembly arranged in the powder bin, the stirring assembly includes a stirring frame and a stirring piece, the stirring frame is rotatable about its own axis, the stirring frame includes a frame rod and a connecting structure arranged at the circumferential position of the frame rod, the connecting structure is used for mounting and connecting the stirring piece, the connecting structure is, for example, a connecting protruding column, the stirring piece is, for example, a blade, the blade is provided with a connecting hole, and the protruding column can anchor the blade after penetrating through the connecting hole and being subjected to hot pressing.

[0003] The existing stirring assembly is generally installed in the powder bin by hand. It is required to realize automatic installation of the stirring frame, the stirring frame needs to be capable of cooperating with the automatic mechanical hand for grabbing, however, the structure design of the existing stirring frame does not consider this, and thus it is difficult to realize automatic transportation at present. SUMMARY

[0004] The first purpose of the utility model is to provide a stirring frame which is beneficial to automatic unloading and assembly in cooperation with automatic equipment.

[0005] The second purpose of the utility model is to provide a stirring assembly which is beneficial to automatic unloading and assembly in cooperation with automatic equipment.

[0006] The third purpose of the utility model is to provide a processing box which can be automatically assembled to improve production efficiency.

[0007] The stirring frame provided by the first purpose of the utility model includes a frame rod arranged at the rotating axis and a connecting structure arranged at the circumferential position of the rotating axis, the connecting structure is used for connecting the stirring piece, and the axial ends of the rotating axis are respectively provided with a first connecting end and a second connecting end; the frame rod is provided with an adsorption cooperation surface; the adsorption cooperation surface is located at the circumferential position of the rotating axis and in the axial direction of the rotating axis, and is located between the first connecting end and the second connecting end; the adsorption cooperation surface is a plane, and the normal line of the adsorption cooperation surface is parallel to the radial direction of the rotating axis.

[0008] From the above scheme, it can be seen that since the clamping and grabbing of the stirring frame and other small parts is difficult, the design of the grabbed part on the stirring frame is also difficult, and therefore the present application considers using adsorption as a means for grabbing the stirring frame, and for this purpose, an adsorption cooperation surface capable of cooperating with the negative pressure suction head needs to be provided on the stirring frame. The adsorption cooperation surface is a plane to ensure the success rate of adsorption and the stability of the carrying process, and the suction head can be adsorbed within the range of the adsorption cooperation surface, thereby reducing the difficulty of grabbing. In addition, the position and orientation of the adsorption cooperation surface also need to be considered. The adsorption cooperation surface is arranged at the middle of the axial direction to avoid affecting the installation and cooperation of the connecting ends at both ends, and also to avoid interference with the wall of the powder bin. In addition, when the negative pressure suction head is pressed against the adsorption cooperation surface, a certain pressure will be applied. If the orientation of the adsorption cooperation surface is inclined, the stirring frame may be deflected or deviated, thereby changing the current state of the stirring frame and affecting the normal progress of subsequent processes such as tray loading or assembly. Therefore, the present application considers arranging the normal of the adsorption cooperation surface parallel to the radial direction of the rotating shaft to avoid causing the stirring frame to deflect or deviate, thereby ensuring the effective progress of subsequent automatic processes.

[0009] A further scheme is that the at least two mutually parallel or coplanar adsorption cooperation surfaces are arranged axially spaced apart.

[0010] As can be seen from the above, since the stirring frame is an elongated part, if there is only one adsorption point, it may fall off during the carrying process due to the action of the large and uneven force on both sides of the adsorption point. Therefore, the present application provides at least two mutually parallel or coplanar adsorption cooperation surfaces and at least two negative pressure suction heads on the robot hand to cooperate one by one, thereby providing more sufficient adsorption force and dispersing the stress, so that the carrying process is in a more stable state and prevents falling off.

[0011] A further scheme is that the frame rod includes a base plate and a protruding structure protruding from the base plate, and the adsorption cooperation surface is arranged on the protruding structure.

[0012] As can be seen from the above, in view of the torsional and bending resistance, the frame rod is arranged in a rib plate structure. With this arrangement, the rib plate is used as the base plate, the protruding structure protruding from the base plate is arranged, and the adsorption cooperation surface is arranged on the protruding structure, which is more suitable for the frame rod with a rib plate structure and reduces the design difficulty.

[0013] A further scheme is that the frame rod is provided with a support cooperation surface, and the support cooperation surface and the adsorption cooperation surface are arranged on opposite sides of the rotating shaft.

[0014] A further scheme is that the support cooperation surface is a plane.

[0015] As can be seen from the above, in the process of automated feeding and assembly, the frame not only needs to cooperate with the robotic arm. This invention considers setting a supporting mating surface opposite to the adsorption mating surface. This supporting mating surface is used to support and position the mixing rack in each automated stage, making it easier to place and position the rack after placement. Furthermore, after being placed and positioned, the adsorption mating surface is in an upward-facing state, making it easier to be adsorbed and grasped. Even better, for mixing racks with a non-circular outer perimeter, setting the supporting mating surface as a plane further facilitates support and placement.

[0016] Another further approach is to have the support mating surface parallel to the adsorption mating surface.

[0017] As can be seen from the above, under this setting, the supporting mating surface parallel to the adsorption mating surface can provide completely opposite counterforces when the stirring rack is adsorbed and pressed down, avoiding the generation of offset force. Even under pressure, the stirring rack can remain stable in its current position.

[0018] Another further design includes a insert plate; the insert plate protrudes perpendicularly from the support mating surface.

[0019] As can be seen above, if only the supporting mating surface is used for positioning, multiple mixing racks arranged in the turnover box may slip during transportation. To ensure that the mixing racks remain within their respective unit areas, the turnover box is provided with slots recessed into the supporting surface. Thus, when the mixing rack is placed in the turnover box and the supporting mating surface mates with the supporting surface, the insert plate is also inserted into the slot to restrict the displacement of the mixing rack.

[0020] A further solution is to install the connection structure on the insert plate.

[0021] As can be seen from the above, in order to ensure the flatness and stability of the blade, the blade is attached to a wall plate for installation. More ingeniously, this utility model uses the wall plate as an insert plate, reducing the need for additional structures while achieving the insert plate function.

[0022] The second objective of this utility model is to provide a stirring assembly comprising a stirring frame and a stirring component connected to each other, wherein the stirring frame is the aforementioned stirring frame.

[0023] The processing box provided by the third objective of this utility model includes the above-mentioned stirring assembly. Attached Figure Description

[0031] First embodiment of the mixing rack

[0032] The processing box of this utility model includes a powder hopper and a stirring assembly installed in the powder hopper. The stirring assembly includes, for example, the following components: Figure 3 The mixing rack 1 and mixing element 2 are shown, with the mixing element 2 being a blade.

[0033] See Figure 1 and Figure 2 In the figure, the x-axis of the spatial rectangular coordinate system represents the axial direction of the rotation axis 100 of the stirring frame 1, which is also the length direction of the stirring frame 1. The stirring frame 1 includes a support rod 11 disposed on the rotation axis 100 and a connecting structure 16 disposed on the circumference of the rotation axis 100. A first connecting end 118 and a second connecting end 119 are respectively disposed at both ends of the axial direction of the rotation axis 100.

[0034] Among them, the connecting structure 16 consists of multiple mounting protrusions spaced apart along the axial direction of the rotation axis 100. After the mounting protrusions pass through the through holes of the stirring component 2, i.e. the blades, the mounting protrusions are heat-fused and cooled to anchor the stirring component 2.

[0035] The first connecting end 118 is a short shaft that extends axially along the rotation axis 100. The short shaft is used to insert into the connecting hole of the powder hopper. The extended end of the short shaft is a tapered part. The tip design of the tapered part can guide the first connecting end 118 during insertion, reducing the difficulty of automating the installation of the stirring assembly into the powder hopper.

[0036] The second connecting end 119 includes an axially recessed insertion hole along the rotation axis 100, which is used to connect with the drive gear of the stirring frame 1.

[0037] The frame rod 11 is configured as a stiffening plate structure to enhance bending and torsional resistance. The frame rod 11 includes a base plate 110, insert plates 16, inner reinforcing ribs 13, outer reinforcing ribs 15, and inner longitudinal plates 17. The base plate 110 and insert plates 16 both extend axially along the rotation axis 100, and the base plate 110 and insert plates 16 are connected at an acute angle. Multiple inner reinforcing ribs 13 are arranged between the base plate 110, insert plates 16, the end plates of the first connecting end 118, and the end plates of the second connecting end 119, forming a... The cavity 107, which has a unidirectional opening in the negative z-axis direction, has an inner reinforcing rib plate 13 extending axially perpendicular to the rotation axis 100 and connecting between the base plate 110 and the insert plate 16. Multiple inner reinforcing rib plates 13 are arranged at intervals along the rotation axis 100. An inner longitudinal plate 17 extends axially along the rotation axis 100 and connects between the multiple inner reinforcing rib plates 13. The two ends of the extended inner longitudinal plate 17 are respectively connected between the end plate of the first connecting end 118 and the end plate of the second connecting end 119.

[0038] In fact, the outer reinforcing rib plate 15 and the inner reinforcing rib plate 13 are integrally formed on the same wall panel, but the outer reinforcing rib plate 15 is located outside the cavity 107 and is connected to the insert plate 16.

[0039] The substrate 110 has an outer surface facing away from the cavity 107. The support rod 11 includes two protrusions 12 that protrude radially from the outer surface of the substrate 110 along the rotation axis 100. Both protrusions 12 are located between the first connecting end 118 and the second connecting end 119, and are axially spaced along the rotation axis 100 and located on both sides of the support rod 11. In addition, in this embodiment, the two adsorption mating surfaces 120 are coplanar.

[0040] The adsorption mating surface 120 is disposed on the protruding structure 12. Corresponding to the protruding structure 12, the adsorption mating surface 120 is located between the first connecting end 118 and the second connecting end 119 in the axial direction of the rotation axis 100. The adsorption mating surface 120 is a plane and is located on the circumference of the rotation axis 100. The normal of the adsorption mating surface 120 is the z-axis direction shown in the figure, and the normal of the adsorption mating surface 120 is parallel to the radial direction of the rotation axis 100.

[0041] See Figure 2 and Figure 3 At the opening of cavity 107, the edge of substrate 110 and the edges of multiple inner reinforcing ribs 13 lie on the same plane, which is the supporting mating surface 130 of this invention. The supporting mating surface 130 and the adsorption mating surface 120 are respectively disposed on opposite sides of the rotation axis 100. The supporting mating surface 130 is planar and parallel to the adsorption mating surface 120. Furthermore, as... Figure 3As shown, the insert plate 14 protrudes from the support mating surface 130 perpendicularly to it and along the negative z-axis. Additionally, the connecting structure 16 protrudes from the outer surface of the external reinforcing rib plate 15 on the upper back of the insert plate 14.

[0042] See Figure 4 The adsorption mating surface 120 is used to mate with the suction head 91. The adsorption mating surface 120 is flat to ensure the success rate of adsorption and the stability of the handling process. The suction head 91 can adsorb as long as it is within the range of the adsorption mating surface 120, reducing the difficulty of gripping. The support mating surface 130 is used for support and positioning mating with the support 921 of the turnover box 92. After the mixing rack is placed, the adsorption mating surface 120 is in an upward position, making it easy to be adsorbed and gripped. In addition, to ensure that the mixing rack 1 can be stably positioned within its respective unit area within the turnover box 92, the turnover box 92 is provided with a slot 922 recessed 92 into the support surface of the support 921. Thus, when the mixing rack 1 is placed in the turnover box and the support mating surface 130 mates with the support surface, the insert plate 14 is also inserted into the slot to restrict the movement of the mixing rack 1. The slot 922 is located along... Figure 4 The spacing shown on the paper is arranged to avoid the connection structure.

[0043] In addition, when the negative pressure suction head presses down against the adsorption mating surface 120, it will apply a certain pressure. If the orientation of the adsorption mating surface 120 is tilted, it may cause the stirring rack 1 to deflect or shift. The support mating surface 130 parallel to the adsorption mating surface 120 can provide a completely opposite counterforce when the stirring rack 1 is adsorbed and pressed down, avoiding the generation of offset component force. Even under pressure, the stirring rack 1 can remain stable in the current position.

[0044] Second embodiment of the mixing rack

[0045] See Figure 5 In this embodiment, the outer periphery of the frame rod has a cylindrical surface 31. The cylindrical surface 31 is used to position and engage with the V-groove 932 of the positioning seat or turnover box. During engagement, the adsorption engagement surface 320 opposite to the cylindrical surface 31 faces upward and can engage with the suction head 91. In this configuration, the cylindrical surface 31 serves as the supporting engagement surface of the stirring frame.

[0046] Third embodiment of the mixing rack

[0047] See Figure 6 In this embodiment, the adsorption mating surface 420 and the support mating surface 430 form an angle.

[0048] Fourth embodiment of the mixing rack

[0049] See Figure 7 In this embodiment, the adsorption mating surface 520 is the surface of the substrate of the support rod. Under this configuration, the stirring rack does not have a protruding structure.

[0050] Finally, it should be emphasized that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
