Description

Technical Field

[0001] This utility model relates to the field of lead bar processing technology, and in particular to a lead bar pelletizing mechanism. Background Technology

[0002] Lead pellets play a crucial role in lead-acid batteries by increasing energy density, extending lifespan, and improving discharge performance. They are typically made by cutting lead strips into pellets. Existing lead strip pelletizing machines include those that continuously feed and cut single lead strips, as well as those that cut multiple lead strips side-by-side simultaneously. Cutting multiple lead strips simultaneously increases the efficiency of lead strip pelletizing.

[0003] Because multiple lead strips are manually placed side by side during pelletizing, the neatness of the lead strips is relatively poor. Furthermore, the limiting effect on multiple lead strips during pelletizing is also poor, which can easily lead to poor neatness between the lead strips, thus having a relatively large impact on the effect and efficiency of lead strip pelletizing. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a lead strip pelletizing mechanism to solve the problem that when multiple lead strips are pelletized, the uniformity between the lead strips is poor, which affects the pelletizing effect and efficiency.

[0005] To achieve the above objectives, this utility model provides a lead strip pelletizing mechanism, including a pelletizing table and a support base fixedly disposed on the top of the pelletizing table. The interior of the support base and the top of the pelletizing table together form a feeding area. The lead strip pelletizing mechanism further includes:

[0006] A lead strip feeding unit is provided in the feeding area, which is used to simultaneously limit and uniformly push several lead strips to move linearly.

[0007] Rotate the shaft cutter located on the vertical surface outside the support base; the shaft cutter is used to cut the lead strip into pellets.

[0008] A drive unit used to simultaneously drive the linear movement of the lead strip feed unit and the rotation of the shaft cutter.

[0009] Preferably, the lead strip pelletizing mechanism further includes a discharge trough located on the top of the pelletizing table, the discharge trough being close to the bottom of the outer vertical surface of the support base.

[0010] Preferably, the driving unit includes:

[0011] An L-shaped support frame is fixed between the top of the pelletizing table and the top of the support base.

[0012] The spindle is located between the cutter and the support frame.

[0013] A drive motor for driving the rotation of the main shaft.

[0014] Preferably, one end of the spindle is fixed at the center of the cutter, and the remaining end of the spindle is rotatably mounted on the support frame.

[0015] Preferably, the driving unit further includes:

[0016] Rotate the lead screw located at the top of the support frame.

[0017] A driven wheel is fixedly sleeved on one end of the lead screw.

[0018] A drive wheel is fixedly sleeved on one end of the main shaft.

[0019] A toothed belt is provided between the driving pulley and the driven pulley for power transmission.

[0020] Preferably, the lead strip feeding unit includes:

[0021] The support arm is slidably connected to the guide groove located on the top of the support base. The top end of the support arm is threaded onto the outside of the lead screw. Several limiting grooves are arranged horizontally side by side on one of the vertical surfaces of the support arm.

[0022] Two guide rods are inserted into the two through holes located on the bottom of the outer side of the support arm.

[0023] A pressure bar is fixedly disposed between the end faces of the two guide rods, and a material insertion groove is provided horizontally and parallelly on one of the vertical surfaces of the pressure bar.

[0024] A spring that is slidably sleeved outside the guide rod.

[0025] Several discharge holes are provided between the vertical surface of the support base and the feeding area.

[0026] Preferably, the two ends of the spring are fixedly disposed on the end face of the guide rod away from the pressure bar and on the support arm, respectively.

[0027] Preferably, the insert groove corresponds to the limiting groove, and the insert groove also corresponds to the discharge hole.

[0028] The beneficial effects of this utility model are:

[0029] This invention utilizes the combination of a limiting groove on the support arm, a material insertion groove on the pressure bar, and a discharge hole to limit the lead strip in a three-point alignment.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0039] like Figure 1 and Figure 2 As shown, a lead strip pelletizing mechanism includes a pelletizing table 1 and a support base 2 fixedly disposed on the top of the pelletizing table 1. The interior of the support base 2 and the top of the pelletizing table 1 enclose a feeding area 3. The lead strip pelletizing mechanism also includes:

[0040] The lead strip feeding part 4 is located in the feeding area 3. The lead strip feeding part 4 is used to simultaneously limit and uniformly push several lead strips to move in a straight line. This ensures the uniformity of the lead strips during the pelletizing process and keeps the cutting degree of multiple lead strips being cut at the same time consistent.

[0041] Rotate the shaft cutter 5 which is located on the vertical surface outside the support base 2. The shaft cutter 5 includes a central shaft and several blades that are uniformly fixed on the outside of the central shaft in a circumferential direction. One side of the blades is attached to the vertical surface outside the support base 2. The shaft cutter 5 is used to cut lead strips into pellets.

[0042] The drive unit 6 is used to simultaneously drive the linear movement of the lead strip feed unit 4 and the rotation of the shaft cutter 5, thus enabling the lead strip to be pushed and cut at the same time, improving the uniformity of the lead strip pellets.

[0043] like Figure 1 and Figure 2 As shown, the lead strip pelletizing mechanism also includes a discharge trough 7 located on the top of the pelletizing table 1. The discharge trough 7 is close to the bottom of the outer vertical surface of the support base 2. This design allows all the lead pellets to fall into the discharge trough 7, preventing the lead pellets from scattering into the working environment and improving the centralized collection effect of the lead pellets.

[0044] like Figure 2 and Figure 3 As shown, the drive unit 6 includes:

[0045] An L-shaped support frame 61 is fixed between the top of the pelletizing table 1 and the top of the support base 2.

[0046] The main spindle 63 is located between the cutter 5 and the support frame 61.

[0047] Drive motor 62 for driving the spindle 63 to rotate.

[0048] One end of the spindle 63 is fixed at the center of the cutter 5, and the other end of the spindle 63 is rotatably mounted on the support frame 61. This allows the drive motor 62 to directly drive the cutter 5 to rotate, so that one end of the lead strip enters the cutting range of the cutter 5 and is cut off in time.

[0049] like Figures 2 to 4 As shown, the drive unit 6 also includes:

[0050] Rotate the lead screw 64 located at the top of the support frame 61.

[0051] A driven wheel 66 is fixedly sleeved on one end of the lead screw 64.

[0052] The drive wheel 65 is fixedly sleeved on one end of the main shaft 63.

[0053] A toothed belt 67 is provided between the driving pulley 65 and the driven pulley 66 for power transmission.

[0054] Lead strip feed section 4 includes:

[0055] The support arm 43 is slidably connected to the guide groove 41 located on the top of the support base 2. The top end of the support arm 43 is threaded onto the outside of the lead screw 64. Several limiting grooves 48 are arranged horizontally side by side on one of the vertical surfaces of the support arm 43. This allows the drive motor 62 to simultaneously drive the support arm 43 to move closer to or away from the shaft cutter 5 while the direct drive shaft cutter 5 rotates to cut pellets, thereby achieving uniform feeding of lead strips and resetting of the support arm 43.

[0056] Two through holes 44 are located on the bottom of the outer side of the support arm 43, and guide rods 45 are inserted into the through holes 44.

[0057] A pressure bar 46 is fixedly installed between the end faces of two guide rods 45, and a material insertion groove 49 is provided horizontally and parallelly on one of the vertical surfaces of the pressure bar 46.

[0058] Spring 47 is slidably sleeved outside guide rod 45.

[0059] Several discharge holes 42 are provided between the vertical surface of the support base 2 and the feeding area 3.

[0060] The two ends of the spring 47 are fixed on the end face of the guide rod 45 away from the pressure bar 46 and the support arm 43, respectively.

[0061] The insert groove 49 corresponds to the limiting groove 48, and the insert groove 49 also corresponds to the discharge hole 42.

[0062] This design ensures that the limiting groove 48, the insert groove 49, and the discharge hole 42 are aligned, maintaining a straight and stable feeding of the lead strip during pelletizing. It also helps to maintain the uniformity of the lead strip before and during pelletizing, reducing the range of differences in lead particle size and improving the uniformity of the lead particles in the shaft cutter 5.

[0063] Working principle: Multiple lead bars are inserted laterally along the axial direction between the corresponding limiting grooves 48 and inserting grooves 49, with one end of the lead bar abutting against the vertical surface of the limiting groove 48 opposite to the inserting groove 49. This maintains the alignment of the lead bars initially, and also ensures that one end of the lead bar only needs to be within the limiting groove 48 without abutting against the vertical surface within the limiting groove 48. As the driving unit 6 drives the support arm 43 towards the discharge hole 42, the lead bars are aligned under the push of the support arm 43, and then the lead bars can be pushed into the corresponding discharge holes. As the lead bars are continuously pushed, the end of the lead bar away from the support arm 43 first passes through the discharge hole 42. The lead strip is cut into fixed-size lead pellets by the rotating shaft cutter 5. During the continuous pushing of the lead strip, the limiting groove 48 and the insert groove 49 continuously limit and guide the lead strip until it is completely cut. During this process, after the pressure bar 46 comes into contact with the inner wall of the support base 2, the guide rod 45 remains stationary as the support arm 43 continues to move, and the spring 47 elastically extends until the lead strip pelleting is finished. When the drive unit 6 drives the support arm 43 to reset, the spring first shortens and recovers, and then pulls the guide rod 45 and the pressure bar 46 to reset. When the drive unit 6 drives the support arm 43 to move, it will simultaneously drive the shaft cutter 5 to rotate, thereby achieving the cutting of the lead strip and improving the uniformity of the lead strip pellets.
