Description

Technical Field

[0001] The utility model relates to the field of powder battery powder pad assembly equipment, in particular to a powder pad pressure replenishing bow rod. Background Art

[0002] At present, in the field of mechanized battery processing in China, in the process of loading carbon powder into zinc shell, most of them adopt a separate operation mode, that is, after filling the carbon powder into the zinc shell, the loaded carbon powder is compacted by the next process, and then the carbon rod is loaded after compaction.

[0003] For example, Chinese patent CN204651396U discloses a battery toner feeding device, which specifically includes a frame, wherein the frame is provided with a pre-filled toner battery holder, a feeding mechanism, a toner preloading mechanism, a pre-punching mechanism and a toner pressing mechanism. The feeding mechanism inputs toner into the toner preloading mechanism, the toner preloading mechanism punches the toner into a pre-filled carbon mold, the pre-punching mechanism punches the toner from the pre-filled carbon mold into a carbon mold, and the toner pressing mechanism punches the toner from the carbon mold into the battery. The utility model battery holder is provided with a plurality of pre-filled toner batteries arranged horizontally, and the feeding, toner preloading, pre-punching and toner pressing are all arranged horizontally. This multi-head powdering mode can powder in batches at the same time, significantly improving production efficiency.

[0004] In the prior art, the compaction of carbon powder is generally carried out by direct pressure. Moreover, for the compacted carbon powder, the final surface is formed into a flat surface under the action of the external pressure force. During the research and development process, the inventor found that after the carbon powder is added, after the grooves are formed on the surface, the carbon rod can be inserted into the carbon powder better and straighter when the carbon rod is filled. In the process of pressing the carbon powder, the existing carbon powder pressing rod easily flattens the grooves formed after the carbon powder is filled, and destroys the grooves formed in the previous process. Utility Model Content

[0005] The utility model aims to provide a powder pad pressing bow rod to solve the problem that the existing carbon powder pressing rod may damage the grooves on the surface of the carbon powder.

[0006] In order to solve the above problems, the utility model adopts the following technical means:

[0007] A powder pad pressure-replenishing bow rod, comprising a pressing material outer bow sleeve and a pressing material inner bow rod;

[0008] A first pressure-maintaining cavity is provided in the press outer bow sleeve, and the press inner bow rod is slidably arranged in the first pressure-maintaining cavity, and one end of the press inner bow rod extends out of the press outer bow sleeve as a press end;

[0009] The first pressure-maintaining chamber is communicated with an external pressure supply mechanism through a pressure supply pipeline arranged in the material pressing outer bow sleeve.

[0010] Preferably, the first pressure-maintaining chamber and the pressure supply pipeline are sealed and filled with hydraulic oil, and the pressure supply mechanism is an oil supply system.

[0011] Furthermore, the inner bow rod of the pressing material includes a displacement block slidably arranged in the first pressure-maintaining cavity, and a compacting rod with a flat bottom surface is installed at the bottom end of the displacement block. The compacting rod extends vertically out of the first pressure-maintaining cavity, and the bottom surface of the displacement block abuts against the bottom of the first pressure-maintaining cavity.

[0012] Furthermore, a truncated cone-shaped conical block is coaxially arranged at the bottom end of the compacting rod, and the small-area end of the conical block is arranged downward.

[0013] Furthermore, a sealing rubber ring is provided on the outer wall of the displacement block.

[0014] Furthermore, the inner diameter of the first pressure-maintaining chamber is the same as the outer diameter of the sliding end of the inner bow rod of the pressing material, the top end of the first pressure-maintaining chamber is connected to the pressure supply pipeline, the top surface of the first pressure-maintaining chamber is a truncated cone, and the pressure supply pipeline is connected to the small area end of the top surface of the first pressure-maintaining chamber.

[0015] Furthermore, a fourth needle bearing is installed on the top side of the press outer bow sleeve, and the liquid inlet end of the pressure supply pipeline is arranged on the side wall of the press outer bow sleeve.

[0016] During use, the utility model has the following beneficial effects:

[0017] When the outer bow sleeve of the press material moves downward to drive the inner bow rod of the press material to press the carbon powder, the press end of the inner bow rod of the press material is used to press the carbon powder in two steps. This not only ensures the pressing effect of the carbon powder in the zinc shell, but also effectively prevents the grooves formed on the surface of the carbon powder in the previous process from being destroyed due to the compaction of the carbon powder. After the carbon powder is compacted, the grooves formed on the surface can be kept intact.

[0018] Furthermore, it can reduce the situation that after a powder pad is added to the surface of the carbon powder in the zinc shell, some carbon powder will leak out from the central through hole of the powder pad. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Please refer to Figure 1The powder pad pressure-replenishing bow rod comprises an outer bow sleeve 201 for pressing materials and an inner bow rod 202 for pressing materials;

[0028] The press outer bow sleeve 201 is provided with a first pressure-maintaining cavity 203, the press inner bow rod 202 is slidably disposed in the first pressure-maintaining cavity 203, and one end of the press inner bow rod 202 extends out of the press outer bow sleeve 201 as a press end;

[0029] The first pressure-maintaining chamber 203 is connected to an external pressure supply mechanism through a pressure supply pipeline 204 disposed in the material pressing outer bow sleeve 201 .

[0030] In this way, the first pressure-maintaining chamber 203 is supplied with pressure through the pressure supply pipeline 204 by using an external pressure supply mechanism, so that the first pressure-maintaining chamber 203 is always in a positive pressure state, and the inner bow rod 202 of the material pressing material is always in contact with the bottom end of the first pressure-maintaining chamber 203 when the material pressing material is not pressing the material. When the carbon powder is pressed, the outer bow sleeve 201 of the material pressing material drives the inner bow rod 202 of the material pressing material to move downward synchronously, so that the pressing end of the inner bow rod 202 of the material pressing material extends into the zinc shell, and the carbon powder in the zinc shell is pressed by the pressing end. When the pressing end acts on the carbon powder in the zinc shell, the carbon powder in the zinc shell is pressed by the inner bow rod 202 under the action of the internal pressure of the first pressure-maintaining chamber 203 in the first pressing stage. In the second stage of pressing, as the carbon powder is compacted, the reaction force of the carbon powder on the pressing end gradually increases. As the outer bow sleeve 201 of the pressing material continues to move downward, the inner bow rod 202 of the pressing material moves upward under the abutment of the carbon powder. When the inner bow rod 202 of the pressing material moves upward, the volume of the first pressure-maintaining chamber 203 is reduced, and the pressure medium filled in the first pressure-maintaining chamber 203 is compressed. While its density increases, it can provide a greater pressure on the pressing end, so that the squeezed pressure medium is used to push the inner bow rod 202 of the pressing material for a second time, and the second stage of pressing is performed. Through the two-stage pressing, in the first stage of pressing, since the downward pressure is smaller than that in the second stage, less pressure can be applied to the looser carbon powder. For carbon powder with grooves on the surface, when the carbon powder near the grooves is pressed, the situation of the carbon powder forming the grooves collapsing into the grooves can be effectively reduced. After the first stage of pressing is completed, in the second stage of pressing, the carbon powder that forms the groove has been initially compacted, and a greater pressing force can be used to compact the entire carbon powder in the zinc shell. Therefore, the two-stage pressing can not only ensure the compaction density of the carbon powder in the zinc shell, but also effectively avoid the problem that the groove formed on the surface of the carbon powder in the previous process is completely destroyed during the pressing process, and the groove cannot be formed after compaction.

[0031] It is precisely because the damage to the grooves on the surface of the carbon powder is reduced that it is possible to effectively avoid a large amount of carbon powder leaking out of the through holes in the middle of the powder pad during the pressing process.

[0032] Furthermore, the first pressure-maintaining chamber 203 and the pressure supply pipeline 204 are sealed and filled with hydraulic oil, and the pressure supply mechanism is an oil supply system.

[0033] In this way, the pressure medium in the first pressure-maintaining chamber 203 is hydraulic oil. By using the oil supply system, the force of the first-stage pressing and the second-stage pressing can be adjusted by adjusting the oil pressure so that they can adapt to the best pressing state.

[0034] Furthermore, the inner bow rod 202 of the material pressing material includes a displacement block 205 slidably arranged in the first pressure-maintaining cavity 203. The displacement block 205 serves as a limiting mechanism for the inner bow rod 202 of the material pressing material. The bottom surface of the displacement block 205 abuts against the bottom of the first pressure-maintaining cavity 203, that is, the movement limit of the displacement block 205 is that its bottom surface abuts against the bottom surface of the first pressure-maintaining cavity 203, and its top surface abuts against the top surface of the first pressure-maintaining cavity 203. A compacting rod 206 with a flat bottom surface is installed at the bottom end of the displacement block 205. The compacting rod 206 extends vertically out of the first pressure-maintaining cavity 203. The bottom end of the aforementioned compacting rod 206 serves as the pressing end of the outer bow sleeve 201 of the material pressing material, and is used to compact the carbon powder inside the zinc shell.

[0035] Furthermore, in order to further ensure that the grooves on the surface of the carbon powder are not damaged by the compaction process, the amount of carbon powder leaking from the through hole in the middle of the powder pad during the compaction process is further reduced.

[0036] The bottom end of the aforementioned compacting rod 206 is coaxially provided with a truncated cone-shaped conical block 207, and the small-area end of the conical block 207 is arranged downward. In this way, the aforementioned conical block 207 matches the shape of the groove formed on the surface of the carbon powder. And the small-area end of the aforementioned conical block 207 can also pass through the middle through hole of the powder pad. In this way, when the carbon powder is compacted by the compacting rod 206, the conical block 207 will pass through the middle through hole of the powder pad and simultaneously extend into the groove on the surface of the carbon powder. The aforementioned conical block 207 not only plays a role in the targeted compaction of the groove formed on the surface of the carbon powder during the compaction process, but also plays a supporting role for the groove to prevent it from collapsing during the compaction process. In addition to protecting the groove, the aforementioned conical block 207 can also block the through hole in the middle of the powder pad to prevent the carbon powder below the powder pad from leaking from the through hole in the middle of the powder pad to the top of the powder pad during the compaction process.

[0037] In order to ensure the pressure-maintaining effect in the first pressure-maintaining cavity 203 and improve the sealing performance of the displacement block 205 , a sealing rubber ring 208 is sleeved on the outer wall of the displacement block 205 .

[0038] Furthermore, the inner diameter of the first pressure-maintaining chamber 203 is the same as the outer diameter of the sliding end of the inner bow rod 202 of the pressing material, the top end of the first pressure-maintaining chamber 203 is connected to the pressure supply pipeline 204, the top surface of the first pressure-maintaining chamber 203 is a truncated cone, and the pressure supply pipeline 204 is connected to the small area end of the top surface of the first pressure-maintaining chamber 203.

[0039] Furthermore, a fourth needle bearing 209 is installed on the top side of the press outer bow sleeve 201 , and the liquid inlet end of the pressure supply pipeline 204 is arranged on the side wall of the press outer bow sleeve 201 .

[0040] The aforementioned fourth needle bearing 209 is used to be slidably arranged in the track used to drive the outer bow sleeve 201 of the press material to operate, so that the outer bow sleeve 201 of the press material can move vertically up and down with the ups and downs of the corresponding track.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
