Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, and in particular to a floating lifting mechanism for the drive wheel of a lifting feeder used for feeding aluminum foil for lithium batteries. Background Technology

[0002] There are increasingly more feeding devices with lifting functions, with various structures and many patented technologies.

[0003] For example, Chinese Patent Application No. 202320523350.0 discloses a feeding machine with a lifting structure, including a base plate, a lifting frame fixedly connected to the top center of the base plate, a drive motor fixedly connected to the inner wall of the bottom end of the lifting frame, a threaded rod fixedly connected to the drive end of the drive motor, a connecting block threadedly connected to the end of the threaded rod near the drive motor, the top end of the threaded rod rotatably connected to the top of the inner wall of the lifting frame, an outer frame fixedly connected to the rear end of the connecting block, and a loading frame rotatably connected to the rear side of the inner wall of the bottom end of the outer frame. This device, by setting an inclined triangular push plate and a loading frame, allows the material to be loaded into the inner wall of the loading frame. The controller can control the servo motor to drive the screw to rotate, causing the inclined triangular push plate to gradually push the loading frame from back to front on the inner wall of the outer frame.

[0004] For example, Chinese Patent Application No. 202221491346.2 discloses a lifting and telescopic feeding device, including a movable frame and a lifting platform mounted on it. A telescopic plate is mounted above the lifting platform. A secondary telescopic mechanism is set between a support plate on the lifting platform and the telescopic plate. The secondary telescopic mechanism is slidably connected to both the lifting platform and the telescopic plate. A cylinder is mounted on the lifting platform to drive the sliding of the secondary telescopic mechanism. The sliding of the secondary telescopic mechanism can cause the telescopic plate to slide in the same direction. An upper slide rail and a lower slide rail are set on the outside of the sliding rod so that the sliding rod can slide on the support plate and the telescopic plate can slide on the sliding rod. The two slide rails increase the sliding distance of the telescopic plate relative to the support plate.

[0005] All of the above-mentioned feeding machinery and equipment are mobile, and they are equipped with rollers or drive wheels or other walking mechanisms. However, the controllability of these wheels is not high, and their adaptability to different working conditions is not high enough. Utility Model Content

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0026] Examples, such as Figure 1-5 As shown, a floating lifting mechanism for the drive wheel of a lifting feeder includes an upright support plate 1, a drive wheel assembly mounted on the support plate 1, and a control component for controlling the lifting and lowering of the drive wheel assembly. A floating support spring 2 for elastically lifting and lowering the drive wheel assembly is abutted between the control component and the control component. The key feature of this application is the floating support spring 2. During the lifting and lowering process of the drive wheel assembly controlled by the control component, as well as in both floating and lowering states, elasticity is maintained. This provides vibration damping, good buffering, and enhanced safety. Furthermore, when the drive wheel assembly lowers, the drive wheel elastically presses against the ground, providing sufficient driving force. The drive wheel assembly is a power unit. When the drive wheel assembly lowers and the drive wheel touches the ground, the feeder can automatically move to transfer materials. However, when precise positioning is required at a specific location or under other conditions, the drive wheel assembly needs to rise because the resistance of rotating on the ground is significant. Rising reduces this resistance. Of course, the feeder itself may have other non-powered rollers or casters. Therefore, by lifting and lowering the drive wheel assembly, it can adapt to different operating environments.

[0027] Specifically, the supporting main board 1 includes a left panel 11 and a right panel 12 spaced apart on the left and right sides, and a bottom reinforcing plate 13 connected between the bottom of the left panel 11 and the right panel 12. The left panel 11 and the right panel 12 of the supporting main board 1 can be installed and fixed with the body of the feeder. This structure has good strength and is also convenient for the installation and connection of the drive wheel assembly and the control assembly.

[0028] Preferably, the control component is located between the left panel 11 and the right panel 12. The control component includes a left drive arm plate 31 and a right drive arm plate 32 spaced apart, and a drive handle 33 connecting the lower rear ends of the left and right drive arm plates 31 and 32. Both the left and right drive arm plates 31 and 32 are inclined downwards to the right. Furthermore, a support beam 34 is rotatably connected between the front portion of the left drive arm plate 31 and the right drive arm plate 32. The floating support spring 2 rests against the lower side of the support beam 34, which is positioned at the front and top. In operation, manual stepping or mechanical pressing of the drive handle 33 causes displacement of the support beam 34, changing the direction of the floating support spring 2 and thus lowering the drive wheel assembly. The optimized structure is as follows.

[0029] An end shaft 30 is threaded between the front portion of the left drive arm plate 31 and the left end of the support beam rod 34, and between the front portion of the right drive arm plate 32 and the right end of the support beam rod 34, to allow the support beam rod 34 to rotate. A left front connecting plate 111 is fixed to the upper right of the front side of the left panel 11, and a right front connecting plate 121 is fixed to the upper left of the front side of the right panel 12. A front hinge shaft 301 is threaded between the left front connecting plate 111 and the front portion of the left drive arm plate 31, and between the right front connecting plate 121 and the front portion of the right drive arm plate 32. The front hinge shaft 301 is located above the support beam rod 34 and the end shaft 30. The axial directions of both the end shaft 30 and the front hinge shaft 301 are in the left-right direction. In this way, the left drive arm plate 31 and the right drive arm plate 32 can rotate around the left panel 11 and the right panel 12, and the support beam rod 34 will be offset along with the left drive arm plate 31 and the right drive arm plate 32, thereby changing the position of the floating support spring 2 to achieve the lowering operation.

[0030] Preferably, the drive wheel assembly includes a swing support plate 41 that abuts against the lower side of the floating support spring 2 and can swing up and down, a drive wheel mounting seat 42 fixed to the front side of the swing support plate 41, and a drive wheel 43 connected to the drive wheel mounting seat 42. The drive wheel 43 can be an existing electric wheel.

[0031] Furthermore, a left rear connecting plate 112 is fixed to the lower right side of the rear side of the left panel 11, and a right rear connecting plate 122 is fixed to the lower left side of the rear side of the right panel 12. The swing support plate 41 passes through the area between the left rear connecting plate 112 and the right rear connecting plate 122. A rear support shaft 40 for swinging the swing support plate 41 is connected between the left rear connecting plate 112, the right rear connecting plate 122, and the rear part of the swing support plate 41. The rear support shaft 40 extends to the left and right. Through the design of this structure, the front part of the swing support plate 41 is swing-type lifting, so the drive wheel 43 is also swing-type lifting.

[0032] Preferably, the support beam 34 and the floating support spring 2 are located on the front side of the support main board 1, and the floating support spring 2 abuts against the support beam 34 and the part of the swing support plate 41 located on the front side of the support main board 1, forming an elastic compressive force on the front side, which makes it easier to realize lifting and lowering.

[0033] To truly achieve lifting and lowering, a crucial element is that a guide limit rod 20 is installed vertically between the support beam 34 and the front portion of the swing support plate 41. This guide limit rod 20 guides the extension and retraction of the floating support spring 2 and prevents the swing support plate 41 from tilting forward and downward on its own. The guide limit rod 20 plays a critical role in stabilizing the structural state. The swing support plate 41 and the bottom reinforcing plate 13 are spaced vertically, allowing for lifting and lowering.

[0034] According to the aforementioned structure, initially, the swing support plate 41 is roughly horizontal and in a raised state, the guide limit rod 20 is also relatively vertical, and the floating support spring 2 is also relatively vertical, which is in a relatively balanced state. Although the swing support plate 41 has a tendency to swing forward and downward according to the structure, with the guide limit rod 20 inserted and the floating support spring 2 supporting it from above and below, it does not have enough force to drive the guide limit rod 20 to tilt forward, that is, it cannot drive the support beam rod 34 to rotate, and is in a suspended stable state. To achieve descent, the drive lever 33 is lowered, causing the left drive arm plate 31 and the right drive arm plate 32 to deflect. This results in a slight upward and forward displacement of the support beam 34, but not enough to cause the guide limit rod 20 and the swing support plate 41 to deflect forward as well. However, there is sufficient force to deflect the support beam 34 downward and backward, causing the guide limit rod 20 to tilt downward and backward as well. The floating support spring 2 tilts downward and backward, creating a downward lever force at the front. This causes the swing support plate 41 to swing downward and forward around the rear support shaft 40, thus achieving the descent. This descent can be set relatively small, typically within one centimeter. After descent, a stable state is reached; without operating the drive lever 33 to raise it, it is difficult to lift the swing support plate 41.

[0035] Of course, although the state is relatively stable after descending or ascending, in order to better lock the state and just in case, we have made the following design: a rear axle seat 51 is fixed on the upper left side of the rear side of the right panel 12. The rear axle seat 51 is connected to a safety shaft 52 that extends to the left and right and can be inserted into the right drive arm plate 32 for locking the operation of the control component. The right drive arm plate 32 has a safety socket 50 that extends to the left and right for the safety shaft 52 to be inserted. The safety socket 50 is located behind the end shaft 30. The safety shaft 52 can be an existing elastic pin to facilitate entering and exiting the safety socket 50. For example, in the initial raised state of the drive wheel assembly, the safety shaft 52 is inserted into the safety socket 50 to achieve complete locking of the raised state. When it is necessary to lower, the safety shaft 52 is removed from the safety socket 50, and the drive lever 33 is lowered to achieve the lowered state. In the lowered state, the safety shaft 52 can pop out again and abut against the upper rear of the right drive arm plate 32. In this way, the right drive arm plate 32 cannot be raised and reset, thus preventing the drive wheel assembly from being raised, and it always remains in the lowered state.

[0036] One approach is to include a corresponding structure on the left side as well. The left drive arm plate 31 also has a safety socket 50, and the rear of the left panel has corresponding bearings and safety shafts. This way, locking in both states is achieved on opposite sides. The raised state can be controlled by the right-side structure, while the lowered state locking can be achieved by the left-side safety shaft. This avoids the need for the right-side safety shaft 52 to re-emerge and engage for locking, as this requires the safety shaft 52 to be precisely against the rear and upper part of the right drive arm plate 32. However, this can be difficult to achieve with longer or shorter drive distances. Therefore, adding another safety structure on the other side is more convenient.

[0037] Preferably, the swing support plate 41 is T-shaped, with the T-head being the portion of the swing support plate 41 located on the front side of the main support plate 1. A circular limiting groove 410 is formed on the T-head portion of the swing support plate 41 for the floating support spring 2 to abut and be limited. There are two circular limiting grooves 410, spaced apart laterally. This design of two floating support springs 2 results in higher structural stability and better support effect.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
