Description

Technical Field

[0001] This utility model relates to the field of printing consumables technology, specifically to a toner cartridge frame, a toner cartridge cover, a toner cartridge body, and a processing box. Background Technology

[0002] Existing laser printing consumables handling cartridges include a toner cartridge body, which comprises a toner cartridge frame and a toner cartridge cover. The toner cartridge frame has a toner cartridge and a toner inlet. The toner cartridge frame includes a peripheral wall surrounding the toner cartridge, and the peripheral wall includes a first surface surrounding the toner inlet. After toner filling, the toner cartridge cover is closed onto the side where the toner inlet is located, and the toner cartridge frame and the toner cartridge cover are welded together to ensure a seamless area around the toner inlet and prevent toner leakage. The toner cartridge frame includes a first surface surrounding the toner inlet, with a raised wire bonding rib around the toner inlet. Conversely, the second surface of the toner cartridge cover has a wire bonding groove. When the toner cartridge cover and toner cartridge frame are closed, the wire bonding rib engages with the wire bonding groove, and during welding, the wire bonding rib and the wire bonding groove are fused together.

[0003] In order to implement the concept of environmental protection, some treatment boxes use recycled plastic as the raw material for the powder hopper frame and powder hopper cover. However, recycled materials have poor welding performance. During the transportation of the treatment boxes, vibration and high temperature can easily cause the powder hopper cover to crack between the powder hopper frame and the powder hopper body, resulting in powder leakage. Utility Model Content

[0004] The primary objective of this invention is to provide a powder hopper frame that solves the problem of powder leakage.

[0005] The second objective of this invention is to provide a powder hopper cover that solves the problem of powder leakage.

[0006] The third objective of this utility model is to provide a powder hopper body that solves the problem of powder leakage.

[0007] The fourth objective of this utility model is to provide a processing box that solves the problem of powder leakage.

[0008] The first objective of this utility model is to provide a powder hopper frame with a powder hopper and a powder inlet. It also includes a peripheral wall surrounding the powder hopper, the peripheral wall including a first surface surrounding the powder inlet, the first surface having a first welding line structure surrounding the powder inlet, the first welding line structure being a protrusion or a groove; on each side of the powder inlet in the length and width directions, in the extension direction of the first welding line structure, at least a portion of the first welding line structure is configured as a multi-line portion, the multi-line portion including at least two first structural segments spaced apart from the inside to the outside.

[0009] As can be seen from the above scheme, at least a portion of each side in both the length and width directions has increased the number of welding lines, which can increase the welding area between the powder hopper frame and the powder hopper cover, strengthen the bond between the two, have a better effect against vibration, and better resist the force generated by deformation at high temperature, avoid welding cracking, and solve the powder leakage problem.

[0010] A further embodiment is that, in the extension direction of the first wire bonding structure, a portion of the first wire bonding structure is configured as a single-wire portion, the single-wire portion including only one second structural segment; the single-wire portion is connected to the multi-wire portion, and multiple first structural segments are connected to the same second structural segment.

[0011] As can be seen from the above, under this setting, when there are single and multiple structures, the two or more first structure segments of the multiple structure are connected to the second structure segment of the single structure to avoid forming a break and ensure that all segments of the first weld wire structure continuously surround the powder inlet. This setting is beneficial to improving the welding effect.

[0012] A further proposed solution is to have a single-line section only on one side of the powder inlet along its length.

[0013] As can be seen from the above, except for the locations where a single-line section is required due to the narrow width of the first surface, two or more first structural sections are provided in other locations to maximize the welding strength.

[0014] A further proposed solution is to make the second structural segment bend at right angles twice.

[0015] As can be seen from the above, under this setting, the second structural segment adapts to the extension trend of the narrower segment on the first surface.

[0016] Another further option is that a first positioning structure is provided on the first surface, the first positioning structure being a positioning hole or a positioning post, and the first positioning structure is located on the inner periphery of the first wire bonding structure; and / or, a second positioning structure is provided on the first surface, the second positioning structure being a positioning hole or a positioning post, and the second positioning structure is located on the outer periphery of the first wire bonding structure.

[0017] As can be seen from the above, the first positioning structure and the second positioning structure are respectively inserted and fitted with the third positioning structure and the fourth positioning structure on the powder hopper cover, thereby achieving pre-positioning before welding the powder hopper cover, which mainly facilitates the alignment of the first welding line structure and the second welding line structure of the powder hopper cover.

[0018] A further approach is to reduce the spacing between multiple first structural segments as they pass through the inner periphery of the second positioning structure, as the multi-line section extends.

[0019] As can be seen from the above, although the setting of the second positioning structure makes the width of the first surface within the inner circumference of the second positioning structure narrower, it is still possible to set two welding lines to maximize the welding strength while reducing the spacing.

[0020] The powder hopper cover provided by the second objective of this utility model includes a second surface, and the second surface is provided with a circumferential second welding line structure, which is a groove or a convex strip; the powder hopper cover is used to cover the powder hopper frame, and the second welding line structure matches the first welding line structure.

[0021] As can be seen from the above scheme, under this setting, the number of welding lines is increased on both sides in the length and width directions, which can increase the welding area between the powder hopper frame and the powder hopper cover, strengthen the connection between the two, have a better effect against vibration, and better resist the force generated by deformation at high temperature, avoid welding cracking, and solve the powder leakage problem.

[0022] A further embodiment is that a first positioning structure is provided on the first surface, located on the inner periphery of the first bonding wire structure, and a third positioning structure is provided on the second surface, located on the inner periphery of the second bonding wire structure. The first positioning structure and the third positioning structure cooperate, with one of the first positioning structure and the other being a positioning post and the other a positioning hole; and / or, a second positioning structure is provided on the first surface, located on the outer periphery of the first bonding wire structure, and a fourth positioning structure is provided on the second surface, located on the outer periphery of the second bonding wire structure. The second positioning structure and the fourth positioning structure cooperate, with one of the second positioning structure and the other being a positioning post and the other a positioning hole.

[0023] The powder hopper body provided by the third objective of this utility model includes a powder hopper frame and a powder hopper cover that covers the powder hopper frame; the powder hopper frame adopts the above-mentioned powder hopper frame, and the powder hopper cover is provided with a second welding wire structure that matches the first welding wire structure.

[0024] The fourth purpose processing box of this utility model includes the powder hopper body mentioned above. Attached Figure Description

[0031] Examples of powder hopper frame, powder hopper cover, powder hopper body and processing box The processing box in this embodiment includes a powder hopper body, which includes, as shown in the example... Figure 1 The powder hopper frame 1 shown and as follows Figure 5 The powder hopper cover 2 shown is welded to the powder hopper frame 1 after being covered by the powder hopper cover 2.

[0032] See Figure 1 and Figure 2 The powder hopper frame 1 is provided with a powder hopper 10 and a powder inlet 100 of the powder hopper 10. The powder hopper frame 1 also includes a peripheral wall 11 surrounding the powder hopper. The peripheral wall 11 includes a first surface 12 surrounding the powder inlet 100. The first surface 12 is provided with a first bonding wire structure 13 surrounding the powder inlet 100. In this embodiment, the first bonding wire structure is a protrusion that protrudes from the first surface 12.

[0033] Along the length direction of the powder inlet 100 ( Figure 2 (left and right directions) and width direction ( Figure 2 On each side of the first wire bonding structure 13 in the upward and downward direction, at least a portion of the first wire bonding structure 13 is configured as a multi-line portion 14. The multi-line portion 14 includes two first structural segments 141 spaced apart from the inside to the outside. That is, the first wire bonding structure 13 is configured on all four sides of the outer periphery of the powder inlet 100 as a structure including two inner and outer raised strip segments.

[0034] Furthermore, in this embodiment, the first bonding wire structure 13 is located on both sides of the width of the powder inlet 100. Figure 2 (as shown on both the upper and lower sides) and one side of the length of the powder inlet 100 (as shown on both sides) Figure 2 The left side (as shown) is entirely set as a multi-line section 14, while only on the other side of the length of the air inlet 100 (as shown) Figure 2 One part of the (shown on the right) is set as a single-line section 15, which includes only one second structural segment, that is, only one convex strip segment.

[0035] Combined Figure 3The single-line portion 15 is connected to the multi-line portion 14, and multiple first structural segments 141 are connected to the same second structural segment. Furthermore, since all extension positions except for the single-line portion 15 are multi-line portions 14, the extension start ends 141a of the two first structural segments 141 are connected to one end of the single-line portion 15 (i.e., the second structural segment itself), and the extension end ends 141b of the two first structural segments 141 are connected to the other end of the first structural segment 15.

[0036] The reason for needing to set a single-line portion 15 is that the location of the first structural segment 15 is relatively narrow, making it difficult to set two protruding strips. Except for the location where a single-line portion 15 is needed due to the narrow width of the first surface 12, two or more layers of the first structural segment 141 are set in other locations to maximize welding strength.

[0037] Furthermore, to accommodate the extension trend of the first surface, the second structural segment of the single-line portion 15 undergoes two right-angle bends. Meanwhile, the two first structural segments 141 of the multi-structure are both connected to the second structural segment of the single structure, avoiding breakpoints and ensuring that all segments of the first weld wire structure 13 continuously surround the powder inlet 100. This arrangement helps improve the welding effect.

[0038] See Figure 1 and Figure 2 The first surface 12 is provided with a first positioning structure 161, which is a square positioning hole, and is disposed on the inner periphery of the first bonding wire structure 13; and the first surface 12 is provided with a second positioning structure 162, which is a circular positioning hole, and is disposed on the outer periphery of the first bonding wire structure 13. Figure 4 As the multi-line portion 14 extends, the interval between the two first structural segments 141 decreases as it passes the inner periphery of the second positioning structure 162.

[0039] Combination Figure 5 The first positioning structure 161 and the second positioning structure 162 are respectively inserted and fitted with the third positioning structure 261 and the fourth positioning structure 262 on the powder hopper cover 2, thereby achieving pre-positioning before welding the powder hopper cover 2, which mainly facilitates the alignment of the first welding line structure 13 and the second welding line structure 23 of the powder hopper cover 2. Although the setting of the second positioning structure 162 makes the width of the first surface 12 within the inner circumference of the second positioning structure 162 narrower, two welding lines can still be set with a reduced spacing to maximize the welding strength.

[0040] See Figure 5 and Figure 6The powder hopper cover 2 is used to cover and weld the powder hopper frame 1 of this utility model. The powder hopper cover 2 includes a second surface 22, which faces the powder hopper frame 1. The second surface 22 is provided with a circumferential second welding line structure 23, which is a groove opposite to the first welding line structure 13. The second welding line structure 23 matches the first welding line structure 13. The second welding line structure 23 is completely set as a second multi-line portion 24 on both sides of the width of the powder inlet 100 and on one side of the length of the powder inlet 100. The second multi-line portion 24 includes two third structural segments 241, while only a portion on one side of the length of the powder inlet 100 is set as a second single-line portion 25. The second single-line portion 25 includes only one fourth structural segment, that is, only one groove segment. Furthermore, the second single-line portion 25 is connected to the second multi-line portion 24, and multiple third structural segments 241 are connected to the same fourth structural segment.

[0041] Additionally, a third positioning structure 261 is provided on the second surface 22, located on the inner periphery of the second bonding wire structure 23. The third positioning structure 261 is a square positioning post, and the first positioning structure 161 and the third positioning structure 261 cooperate with each other. A fourth positioning structure 262 is provided on the second surface 22, located on the outer periphery of the second bonding wire structure 23. The fourth positioning structure 262 is a circular positioning post, and the second positioning structure 162 and the fourth positioning structure 262 cooperate with each other.

[0042] In this embodiment, the number of welding lines is increased on at least each side of the powder inlet in both the length and width directions, increasing the welding area between the powder hopper frame 1 and the powder hopper cover 2, strengthening the bond between the two, providing better resistance to vibration, and better resisting the force generated by deformation under high temperature, thus avoiding welding cracks and solving the powder leakage problem.

[0043] In other embodiments, the powder hopper frame of other types of processing boxes, if the width of the first surface is sufficient, can be entirely set as a multi-line section (without a single-line section), and the multi-line section can include three or more first structural segments.

[0044] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
