Description

Technical Field

[0001] The utility model relates to the technical field of lead-acid battery plate production equipment, in particular to an accelerated continuous conveying mechanism. Background Art

[0002] The production process of lead-acid battery plates mainly includes the following steps: coating a continuous lead strip with paste and then covering it with paste paper to obtain a continuous plate, cutting the continuous plate to obtain a single plate, stacking the single plates to obtain a plate stack, and drying and curing the plate stack to obtain a finished plate.

[0003] The wet plates obtained by cutting are introduced into the sheet collection equipment. The continuous conveying of wet plates is mostly completed by conveyor belts. The conveyor belts convey the wet plates at a constant speed. If the conveying speed is too high, the wet plates and the working surface of the conveyor belt will easily slip, causing the wet plates to deviate at different angles. Due to the limited conveying speed, the inertia of the wet plates at the discharge end of the conveyor belt is limited, which often causes the wet plates to be too short to the conveyor belt on the discharge side of the conveyor belt, which does not meet the predetermined stacking or discharge requirements.

[0004] Therefore, it is necessary to improve the structure of the continuous plate conveying mechanism. Utility Model Content

[0005] The utility model aims to overcome the defects in the prior art and provides an accelerating continuous conveying mechanism, which utilizes the speed difference between a first conveying belt and an accelerating mechanism to make the conveyed electrode plate have acceleration in a first direction and increase the inertial force of the electrode plate.

[0006] In order to achieve the above technical effects, the technical solution of the utility model is: an accelerated continuous conveying mechanism, comprising:

[0007] A first conveyor belt having a first working surface extending in a first direction;

[0008] The acceleration mechanism has a feed end disposed on the side of the discharge end of the first conveyor belt in a first direction, and a conveying speed along the first direction greater than a conveying speed of the first conveyor belt.

[0009] A preferred technical solution is that the acceleration mechanism includes a second conveyor belt having a second working surface whose length extends along the first direction, and a feed end of the second working surface is flush with or lower than a discharge end of the first working surface.

[0010] A preferred technical solution is that the acceleration mechanism includes a first acceleration roller rotatably arranged on the discharge side of the first conveyor belt, the top end of the roller surface of the first acceleration roller is located in the plane where the first working surface is located, or the top end of the roller surface of the first acceleration roller is lower than the plane where the first working surface is located.

[0011] A preferred technical solution is that the acceleration mechanism includes a second acceleration roller rotatably arranged on the discharge side of the second conveyor belt, the top end of the roller surface of the second acceleration roller is located in the plane where the second working surface is located, or the top end of the roller surface of the first acceleration roller is lower than the plane where the second working surface is located.

[0012] A preferred technical solution is that the conveying speeds of the first conveyor belt, the second conveyor belt and the second acceleration roller increase sequentially along the first direction.

[0013] A preferred technical solution is that the first conveyor belt is provided with an adjustment mechanism, and the adjustment mechanism is configured to adjust the height of the discharge end of the first working surface.

[0014] The preferred technical solution is that the adjustment mechanism includes a rotating shaft, a telescopic member, and a hinge seat fixedly arranged on the first conveyor belt, and the hinge seat is located on the first direction discharge side of the rotating shaft;

[0015] The rotating shaft is fixedly connected to the feed end of the first conveyor belt and is parallel to the transmission shaft of the first conveyor belt or coincides with the central axis, and the rotating shaft is rotatably connected to the frame;

[0016] One of the two ends of the telescopic member is connected to the frame, and the other end is connected to the hinge seat.

[0017] A preferred technical solution is that the second conveyor belt is provided with a supporting member, and the supporting member has a supporting surface that supports the second working surface.

DETAILED DESCRIPTION

[0029] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0030] In the description of the present application, it should be noted that, unless otherwise specified, “plurality” means more than two; the terms “upper”, “lower”, “left”, “right”, “inside”, “outside”, etc., indicating directions or positional relationships, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. Example

[0032] like Figure 1-4 As shown, the embodiment of the accelerating continuous conveying mechanism includes a first conveyor belt 1 and an accelerating mechanism 2, the first conveyor belt 1 has a first working surface whose length extends along a first direction; the feeding end of the accelerating mechanism 2 is arranged on the side of the discharging end of the first conveyor belt 1 in the first direction, and the conveying speed of the accelerating mechanism 2 along the first direction is greater than the conveying speed of the first conveyor belt 1.

[0033] Taking the plate as an example, the first conveyor belt 1 conveys the plate at a constant speed, and the acceleration mechanism 2 increases the conveying speed of the plate, so that the plate generates inertial force. The conveying distance between the first conveyor belt 1 and the acceleration mechanism 2 is L1. Compared with the first conveyor belt 1 with a length of L1, the inertial force generated by the acceleration can discharge the plate to a position farther away from the acceleration mechanism 2.

[0034] like Figure 1 As shown, in some preferred embodiments, the acceleration mechanism 2 includes a second conveyor belt 201, the second conveyor belt 201 has a second working surface extending along the first direction, and the feeding end of the second working surface is flush with or lower than the discharging end of the first working surface.

[0035] The conveying length of the second conveyor belt 201 is determined according to the acceleration change of the electrode plate. The conveying speed of the second conveyor belt 201 is greater than that of the first conveyor belt 1, and the distance between the front and rear electrode plates on the second working surface is greater than that on the first working surface, so as to avoid the front and rear electrode plates overlapping each other after being offset on the second working surface, and the discharge affecting each other.

[0036] like Figure 5 As shown, in some preferred embodiments, the acceleration mechanism 2 includes a first acceleration roller 202 rotatably arranged on the discharge side of the first conveyor belt 1, and the top of the roller surface of the first acceleration roller 202 is located in the plane where the first working surface is located, or the top of the roller surface of the first acceleration roller 202 is lower than the plane where the first working surface is located.

[0037] The first accelerating roller 202 can accelerate the electrode plate, but has no function of increasing the distance between the electrode plates on the second working surface. It can be understood that the first accelerating roller 202 and the electrode plate have a large friction force to prevent the first accelerating roller 202 and the electrode plate from slipping. Specifically, the first accelerating roller 202 is a rubber roller, and further, the roller surface of the first accelerating roller 202 is set to a concave-convex surface to increase the friction force.

[0038] like Figure 1 As shown, in some preferred embodiments, the acceleration mechanism 2 includes a second acceleration roller 203 rotatably arranged on the discharge side of the second conveyor belt 201, the top of the roller surface of the second acceleration roller 203 is located in the plane where the second working surface is located, or the top of the roller surface of the first acceleration roller 202 is lower than the plane where the second working surface is located.

[0039] The roller surface material and roller surface structure of the second accelerating roller 203 can be the same as those of the first accelerating roller 202 .

[0040] The second conveyor belt 201 and the second accelerating roller 203 are sequentially arranged along the first direction, and have the dual functions of accelerating the plates and increasing the distance between the plates. Optionally, the second conveyor belt 201 and the second accelerating roller 203 have the same conveying speed in the first direction.

[0041] like Figure 1 , 2 As shown, in some preferred embodiments, the conveying speeds of the first conveyor belt 1, the second conveyor belt 201 and the second accelerating roller 203 increase in sequence along the first direction. The electrode plate is transferred along the path of the first conveyor belt 1, the second conveyor belt 201 and the second accelerating roller 203, and is accelerated twice by the second conveyor belt 201 and the second accelerating roller 203, so that the inertial force driving the electrode plate to be discharged further increases with the acceleration, and the distance between the second accelerating roller 203 and the electrode plate discharge position is further increased.

[0042] like Figure 3 , 4 As shown, in some preferred embodiments, the first conveyor belt 1 is provided with an adjusting mechanism 3, and the adjusting mechanism 3 is configured to adjust the height of the discharge end of the first working surface.

[0043] The first conveyor belt 1 and the second conveyor belt 201 are butted together front and back along the same conveying direction (X direction in the figure). The height of the discharge end of the first conveyor belt 1 determines the discharge direction, the drop position and the initial velocity of the electrode plate on the second conveyor belt 201. The height of the discharge end of the first conveyor belt 1 is specifically determined according to the inertia force of the electrode plate.

[0044] like Figure 3 , 4 As shown, in some preferred embodiments, the adjustment mechanism 3 includes a rotating shaft 301, a telescopic member and an articulated seat 302 fixedly arranged on the first conveyor belt 1, and the articulated seat 302 is located on the first direction discharge side of the rotating shaft 301; the rotating shaft 301 is fixedly connected to the feed end of the first conveyor belt 1 and is parallel to the transmission shaft 101 of the first conveyor belt 1 or the center axis coincides with each other, and the rotating shaft 301 is rotatably connected to the frame 4; one of the two ends of the telescopic member 303 is connected to the frame 4, and the other end is connected to the articulated seat 302.

[0045] The first conveyor belt 1 rotates around the rotating shaft 301 to adjust the height of its discharge end without changing the height of the feed end of the first conveyor belt 1, so as to meet the docking of the first conveyor belt 1 and its feed equipment. The height adjustment mechanism 3 of the first conveyor belt 1 is suitable for the modification of existing equipment.

[0046] The telescopic member can be selected from known components such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder, etc.

[0047] While rotating the first conveyor belt 1 to adjust the height of its discharge end, the distance between the discharge end of the first conveyor belt 1 and the second conveyor belt 201 is also adjusted to accommodate the transfer of plates of different sizes between the two conveyor belts.

[0048] like Figure 2 As shown, in some preferred embodiments, the second conveyor belt 201 is provided with a supporting member 2011, and the supporting member 2011 has a supporting surface for supporting the second working surface.

[0049] Compared with the first conveyor belt 1, the second conveyor belt 201 has a higher conveying speed. The supporting member 2011 is provided to improve the flatness of the second working surface and avoid the influence of the tension of the second conveyor belt 201 on the plate conveying, especially to reduce the probability of deviation of the plate in the high-speed conveying state, so that the plate discharged by the second conveyor belt 201 can be positioned more accurately.

[0050] Furthermore, the first conveyor belt 1 is also provided with corresponding supporting members to meet the production requirements of high-speed transportation of the electrode plates on the first conveyor belt.

[0051] like Figure 3 As shown, in some preferred embodiments, the rotating shaft 301 coincides with the central axis of the transmission shaft 101 ; the rotating shaft 301 is tightly matched with the driving sprocket 102 of the first conveyor belt 1 .

[0052] The driving sprocket 102 is connected to the driving motor. The bracket 103 of the first conveyor belt 1 is rotatably connected to the transmission shaft 101 through a bearing.

[0053] like Figure 1 As shown, in some preferred embodiments, the first conveyor belt 1 and the second conveyor belt 201 are both conveyor chains.

[0054] For short-distance conveyor chains, it is optional to not have a tensioning device. The conveyor chain has high transmission efficiency and precision and a long service life. However, a tensioning device must be installed on flat belt conveyor belts.

[0055] Furthermore, the conveying chain is a cover plate chain capable of bearing a relatively large load, and the chain links of the cover plate chain have a flat working surface to ensure that the electrode plates obtained by the conveying chain have a flat plate surface.

[0056] The working process of the accelerated lead-out mechanism of the electrode plate or electrode plate stack in the embodiment includes the following steps (taking the electrode plate as an example):

[0057] S1: The electrode plates are discharged from the feeding mechanism or the feeding conveyor belt to the first conveyor belt 1;

[0058] S2: the first conveyor belt 1 uniformly conveys the electrode plate at a first speed until the electrode plate is led out to the second conveyor belt 201 through the discharge end of the first conveyor belt 1;

[0059] S3: the second conveyor belt 201 uniformly conveys the electrode plate at a second speed greater than the first speed, until the electrode plate is led out to the second acceleration roller 203 through the discharge end of the second conveyor belt 201;

[0060] S4: The second accelerating roller 203 has a third speed (linear speed) equal to or greater than the second speed. The second accelerating roller 203 guides the electrode plate to its discharge side, completing the accelerated continuous conveying of the electrode plate.

[0061] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
