Description

Technical Field

[0001] The utility model relates to the field of powder battery powder pad assembly equipment, in particular to a powder pad feeding 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 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 this way, on the one hand, the powder material will not be pre-processed during the powder pressing process. On the other hand, in the prior art, it is also rare to place a powder pad on the top surface of the carbon powder when compacting the carbon powder to avoid the problem of carbon powder splashing during the subsequent insertion of the carbon rod. Utility Model Content

[0005] The utility model aims to provide a powder pad feeding bow rod to solve the problem that it is difficult to quickly load the powder pad after the carbon powder is filled.

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

[0007] A powder pad feeding bow rod, comprising a powder pad positioning rod and a positioning pressing rod;

[0008] The positioning and pressing rod is slidably sleeved on the outside of the powder pad positioning rod;

[0009] One end of the powder pad positioning rod extends out of the positioning and pressing rod, and is used to position the powder pad as a feeding part, and the end of the feeding part is set as a cone head structure;

[0010] One end of the positioning and pressing rod facing the feeding part is used to push the powder pad sleeved on the feeding part.

[0011] Preferably, the cone head structure is a truncated cone head, and the small-area end of the cone head structure is arranged at the distal end of the feeding part.

[0012] Further, the powder pad positioning rod includes a feeding inner bow rod disposed within the positioning and pressing rod, and a material rod disposed at the bottom end of the feeding inner bow rod. The material rod serves as the feeding part, and at one end of the feeding inner bow rod opposite to the material rod, a needle roller bearing with a horizontal rotating shaft is installed protruding from the positioning and pressing rod.

[0013] Furthermore, the outer diameter of the material rod is adapted to the inner diameter of the middle through-hole of the powder pad.

[0014] Furthermore, the positioning and pressing rod includes a feeding outer bow sleeve sleeved outside the powder pad positioning rod. At one end of the feeding outer bow sleeve facing the feeding part, a pushing rod is configured. The feeding part is coaxially disposed within the pushing rod, and the pushing rod is used to push the powder pad sleeved on the feeding part.

[0015] Furthermore, the pushing rod is inserted into the feeding outer bow sleeve, and the inserted end of the pushing rod serves as a limiting mechanism for the powder pad positioning rod.

[0016] Furthermore, the pushing rod includes a limiting tube inserted into the feeding outer bow sleeve and a pushing tube coaxially connected to the limiting tube. The limiting tube and the feeding outer bow sleeve are detachably connected through a pin structure, and the sliding body of the feeding part and the powder pad positioning rod are detachably connected through a threaded structure.

[0017] During the use of the present utility model, the following beneficial effects are achieved:

[0018] When the powder pad is directly below the feeding bow rod, the powder pad positioning rod moves downward alone. The feeding part of the powder pad positioning rod passes through the central through-hole of the lower powder pad, allowing the powder pad to be sleeved on the outer wall of the feeding part. When the entire feeding bow rod moves above the zinc shell filled with carbon powder, the powder pad positioning rod and the positioning and pressing rod move downward simultaneously, enabling the feeding part sleeved with the powder pad to extend into the zinc shell. Then, the positioning and pressing rod moves downward to push the powder pad sleeved on the feeding part downward, causing the powder pad to fall off from the feeding part and enter the top surface of the carbon powder layer in the zinc shell. Moreover, as the feeding part descends, the conical head structure can form an inverted conical groove on the top surface of the carbon powder layer in the zinc shell, facilitating the insertion of the carbon rod in subsequent processes. After the powder pad is placed, the powder pad positioning rod and the positioning and pressing rod move upward simultaneously to withdraw from the zinc shell, completing the powder pad feeding operation.

[0028] Please refer to Figure 1 and Figure 2 shown in, a powder pad feeding bow rod, comprising a powder pad positioning rod 101 and a positioning pressure rod 102;

[0029] The positioning pressure rod 102 is slidably sleeved outside the powder pad positioning rod 101;

[0030] One end of the powder pad positioning rod 101 extends out of the positioning pressure rod 102 and is used to position the powder pad as the feeding part, and the end of the feeding part is provided with a cone head structure 103;

[0031] One end of the positioning pressure rod 102 facing the feeding part is used to push the powder pad sleeved on the feeding part.

[0032] In this way, when the powder pad is directly below the feeding bow rod, the powder pad positioning rod 101 moves downward alone, and the feeding part of the powder pad positioning rod 101 passes through the central through hole of the lower powder pad, so that the powder pad is sleeved on the outer wall of the feeding part. When the feeding bow rod moves as a whole above the zinc shell filled with carbon powder, the powder pad positioning rod 101 and the positioning pressure rod 102 move downward simultaneously, so that the feeding part sleeved with the powder pad extends into the zinc shell. Then the positioning pressure rod 102 moves downward to push the powder pad sleeved on the feeding part downward, so that the powder pad falls off from the feeding part and enters the top surface of the carbon powder layer in the zinc shell. Moreover, as the feeding part descends, the cone head structure 103 can form an inverted conical groove on the top surface of the carbon powder layer in the zinc shell, so as to facilitate the insertion of the carbon rod in the subsequent process. After the powder pad is placed, the powder pad positioning rod 101 and the positioning pressure rod 102 move upward simultaneously and withdraw from the zinc shell to complete the powder pad feeding operation.

[0033] Furthermore, the aforementioned cone head structure 103 is a frustum-shaped cone head, and the small area end of the cone head structure 103 is arranged at the distal end of the feeding part.

[0034] Furthermore, by using the frustum-shaped cone head structure 103, an inverted frustum-shaped groove that is not easily collapsed can be formed on the top of the carbon powder layer in the zinc shell. It can not only facilitate the insertion of the subsequent carbon rod by using the plane of the bottom surface of the inverted frustum-shaped groove, but also avoid a large amount of collapse of the formed groove when the carbon powder is compacted.

[0035] Meanwhile, by using the frustum-shaped cone head structure 103 described above, when scraping the powder pad sleeved on the feeding part with the positioning pressure rod 102, after the cone head structure 103 is buried in the inverted carbon powder, the powder pad only needs to enter the cone head structure 103 from the round rod structure of the feeding part, and the powder pad can be detached from the feeding part. Therefore, in the state where the cone head structure 103 is not completely immersed in the carbon powder, even if the powder pad positioning rod 101 and the positioning pressure rod 102 move upward simultaneously after grooving the carbon powder, the powder pad sleeved on the feeding part can fall into the zinc shell and be placed flat on the top surface of the carbon powder.

[0036] More specifically, for the powder pad positioning rod 101, the powder pad positioning rod 101 includes a feeding inner bow rod 104 disposed inside the positioning pressure rod 102 and a material rod 105 disposed at the bottom end of the feeding inner bow rod 104. The material rod 105 serves as the feeding part, and one end of the feeding inner bow rod 104 opposite to the material rod 105 extends out of the positioning pressure rod 102 and is installed with a first needle roller bearing 106 with a horizontal rotating shaft.

[0037] Among them, the up-and-down movement of the powder pad positioning rod 101 is realized by the first needle roller bearing 106 sliding in different undulating tracks. When the first needle roller bearing 106 moves into the downward-sloping track, the feeding inner bow rod 104 moves downward. When the first needle roller bearing 106 moves into the upward-sloping track, the feeding inner bow rod 104 moves upward. The up-and-down movement of the feeding inner bow rod 104 drives the up-and-down movement of the material rod 105, and the powder pad is sleeved on a section of the material rod 105 extending out of the positioning pressure rod 102 through the through hole in the center of the powder pad.

[0038] Therefore, the end of the aforementioned material rod 105 is configured as the cone head structure 103.

[0039] Moreover, in order to enable the material rod 105 to better sleeve the powder pad, the outer diameter of the aforementioned material rod 105 is adapted to the inner diameter of the middle through hole of the powder pad. In order to improve the stability of the powder pad during movement, the outer diameter of the material rod 105 is slightly larger than the inner diameter of the middle through hole of the powder pad to realize the stable sleeving of the powder pad on the material rod 105.

[0040] Furthermore, for the positioning pressure rod 102, the aforementioned positioning pressure rod 102 includes an outer feeding bow sleeve 107 sleeved outside the powder pad positioning rod 101. One end of the outer feeding bow sleeve 107 facing the feeding part is configured with a push rod 108. The feeding part is coaxially disposed inside the push rod 108. The push rod 108 is used to push the powder pad sleeved on the feeding part. A second needle roller bearing 109 with a horizontal rotating shaft is installed on the outer side wall of the outer feeding bow sleeve 107.

[0041] For the up and down movement of the positioning pressure rod 102, it is adjusted by moving the second needle roller bearing 109 into different undulating tracks. When the second needle roller bearing 109 moves into the downward-sloping track, the feeding outer bow sleeve 107 drives the push rod 108 to move downward together; conversely, when the second needle roller bearing 109 moves into the upward-sloping track, the feeding outer bow sleeve 107 drives the push rod 108 to move upward together. Thus, by using the relative movement of the push rod 108 with respect to the feeding part in the powder pad positioning rod 101, that is, by making the push rod 108 move relative to the material rod 105, the powder pad sleeved on the material rod 105 is pushed to fall into the zinc shell.

[0042] For the movement relationship between the powder pad positioning rod 101 and the positioning pressure rod 102, it can be achieved by setting two tracks that cooperate with each other.

[0043] Furthermore, the push rod 108 is inserted into the feeding outer bow sleeve 107, and the insertion end of the push rod 108 serves as the limiting mechanism of the powder pad positioning rod 101.

[0044] Specifically, the top end of the aforementioned push rod 108 faces the bottom end of the feeding inner bow rod 104, and the outer diameter of the material rod 105 is smaller than the inner diameter of the feeding outer bow sleeve 107. Thus, the distance between the bottom end of the feeding inner bow rod 104 and the top end of the push rod 108 serves as the distance by which the powder pad positioning rod 101 can move relative to the positioning pressure rod 102. By using the abutment between the top end of the push rod 108 and the bottom end of the feeding inner bow rod 104, the relative movement between the powder pad positioning rod 101 and the positioning pressure rod 102 is limited.

[0045] Moreover, in order to facilitate the disassembly, assembly, and maintenance of the entire feeding bow rod, the push rod 108 includes a limiting tube 110 inserted into the feeding outer bow sleeve 107 and a push tube 111 coaxially connected to the limiting tube 110. The limiting tube 110 is detachably connected to the feeding outer bow sleeve 107 through a pin structure 112, and the feeding part is detachably connected to the sliding body of the powder pad positioning rod 101 through a threaded structure 113.

[0046] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
