[0002] Existing feeding devices consist of upper and lower rollers. The lower roller acts as the driving wheel, providing the material with propulsion. The upper roller merely compresses the material, acting as a driven wheel and not directly providing power. Because only the lower roller provides power, material movement is completely dependent on the rotation of the lower roller. This single power source results in uneven force on the material during movement, affecting its smooth and accurate movement and failing to meet the required positioning accuracy for feeding.

[0068] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field should fall within the scope of protection of the embodiments of the present application.

[0069] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. The following embodiments and features thereof may be combined with one another unless they conflict with each other. The steps in the following method embodiments are for illustrative purposes only and are not intended to limit the present invention.

[0070] Existing feeding devices consist of upper and lower rollers. The lower roller acts as the driving wheel, providing the material with forward momentum. The upper roller merely compresses the material, acting as a driven wheel and not directly providing power. Because only the lower roller provides power, material movement is entirely dependent on the rotation of the lower roller. This single power source subjects the material to uneven forces during movement, affecting its smooth and accurate movement. This results in inaccurate length positioning during rapid feeding, failing to meet feeding precision requirements.

[0071] Based on the various problems in the above-mentioned prior art, the embodiments of the present application provide a feeding device, in which the upper roller and the lower roller for clamping the material are both driving wheels; the present application dynamically connects the second driving wheel located above with the output shaft of the feeding motor through a power transmission component, so that the feeding motor can drive the second driving wheel in the clamping position, and at the same time, the power transmission component can enable the second driving wheel to move relative to the first driving wheel to clamp and release the material, thereby meeting different working conditions of the feeding equipment.

[0072] The feeding equipment provided in each embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0073] The feeding device of this embodiment includes a feeding mechanism 10 and a release mechanism 20. Figure 1-Figure 3 shown.

[0074] like Figure 1 As shown, the feeding mechanism 10 includes a feeding motor 11, a first driving wheel 12, a second driving wheel 13, a power transmission shaft 15 and a power transmission component 14, wherein the second driving wheel 13 is located above the first driving wheel 12 along the first direction 700; the first driving wheel 12 is sleeved on the feeding motor output shaft 111 and fixedly connected thereto, and the second driving wheel 13 is sleeved on the power transmission shaft 15 and fixedly connected thereto; the feeding motor output shaft 111 is kinetically connected to the power transmission shaft 15 through the power transmission component 14 to enable the second driving wheel 13 to move in a first plane, wherein the first plane is perpendicular to the center axis of the second driving wheel 13.

[0075] When the second driving wheel 13 is in the clamping position, the second driving wheel 13 is located directly above the first driving wheel 13 and a first preset gap is maintained between the two to clamp the material 80. At this time, the feeding motor 11 can drive the second driving wheel 13 and the first driving wheel 12 to rotate in opposite directions at the same speed through the power transmission component 14.

[0076] The release mechanism 20 is used to drive the second driving wheel 13 to move between a clamping position and a release position, wherein the release position is a position where the second driving wheel 13 moves away from the first driving wheel 12 in the first direction 700 to free the material 80.

[0077] Continuous feeding equipment is a highly efficient automated device used to continuously transport materials to downstream equipment for processing. For example, when the downstream equipment is a stamping machine, the feeding equipment feeds the material into the stamping machine according to a preset length, and the stamping machine stamps the material into the desired shape or part. In a feeding cycle, the feeding equipment operates as follows:

[0078] (1) Clamp the material to ensure that it does not shift during transportation.

[0079] (2) Convey the material according to the preset length. After the material is clamped, the feeding equipment starts to convey the material according to the preset length.

[0080] (3) When the material has traveled a preset length, the feeding equipment stops conveying;

[0081] (4) After stopping the conveying, the feeding equipment will release the material to make the material free so that the downstream equipment can process the material.

[0082] (5) After releasing the material, the feeding equipment enters a stationary state and waits for the downstream equipment to complete processing.

[0083] The continuous feeding equipment repeats the above actions periodically, ensuring the continuity and efficiency of the production process.

[0084] When the feeding device of this embodiment is in the feeding state, the second driving wheel 13 is located in the clamping position, that is, the second driving wheel 13 is located directly above the first driving wheel 12 and there is a first preset gap L1 between the two. Figure 6 As shown, the gap causes the material 80 to be clamped between the first driving wheel 12 and the second driving wheel 13. The feeding motor 11 drives the first driving wheel 12 through the feeding motor output shaft 111, and drives the second driving wheel 13 through the power transmission component 14, so that the two rotate in opposite directions at the same speed, thereby providing power for the material 80 to move. The release mechanism 20 is used to drive the second driving wheel 13 to move between the clamping position and the release position. Figure 7 As shown, when the second driving wheel 13 is in the release position, the second driving wheel 13 moves away from the first driving wheel 12 in the first direction 700, thereby releasing the material 80 to make it free so that the downstream equipment can process the material 80.

[0085] like Figure 1 As shown, the material carrying platform 55 is located between the first driving wheel 12 and the second driving wheel 13 , the outer edge of the first driving wheel 12 is slightly higher than the upper surface of the material carrying platform 55 , and the strip or sheet material 80 is placed between the first driving wheel 12 and the second driving wheel 13 .

[0086] Upon receiving a release command, the release mechanism 20 drives the second driving wheel 13 from the clamping position to the release position, thereby moving the second driving wheel 13 away from the first driving wheel 12 in the first direction 700. At this time, the material 80 is released and is in a free state for subsequent processing. Upon receiving a clamping command, the release mechanism 20 drives the second driving wheel 13 from the release position to the clamping position.

[0087] In some embodiments, the power transmission assembly 14 includes a fixed portion 141 and a floating portion 142. Figure 2 and Figure 3 As shown, the fixed part 141 includes a first gear 1411 and a second gear 1412 that are meshed with each other, wherein the first gear 1411 is fixedly connected to the feeding motor output shaft 111, and the floating part 142 is movably connected to the second gear 1412 so that the floating part 142 can move relative to the fixed part 141 in a first plane.

[0088] like Figure 6As shown, when the second driving wheel 13 is in the clamped position, the center of the second driving wheel 13 coincides with the center of the second gear 1412 on the first plane, allowing the feed motor 11 to drive the second driving wheel 13 to achieve power transmission. When the release mechanism 20 is in operation, the floating portion 142 can move relative to the fixed portion 141, thereby achieving power transmission when the position of the transmission shaft 15 and the second driving wheel 13 is adjusted. In this embodiment, the provision of the floating portion 142 allows the second driving wheel 13 to flexibly adjust its position to meet different operating conditions.

[0089] In some embodiments, the floating portion 142 includes a cross wheel 1421 and a first roller 1422. Figure 2 -As shown in FIG4 , the cross wheel 1421 is located between the second gear 1412 and the first roller 1422. Figure 4A and Figure 4B As shown, the first end of the cross wheel 1421 is provided with a first groove 14211, and the second end of the cross wheel 1421 is provided with a second groove 14212. The extension direction of the second groove 14212 is perpendicular to the extension direction of the first groove 14211. The second end of the second gear 1412 is provided with a third groove 14121 that matches the first groove 14211. The first end of the first roller 1422 is provided with a fourth groove 14221 that matches the second groove 14212. The first slider 145 is installed in the first groove 14211 and the third groove 14121 to enable the cross wheel 1421 to be slidably connected to the second gear 1412. The second slider 146 is installed in the second groove 14212 and the fourth groove 14221 to enable the cross wheel 1421 to be slidably connected to the first roller 1422. The second end of the first roller 1422 is fixedly connected to the power transmission shaft 15.

[0090] Through the vertical movement of the first slider 145 and the second slider 146 , the second driving wheel 13 can flexibly adjust its position in the first plane, while also ensuring its power transmission in the clamping position.

[0091] In some embodiments, the fixed portion 141 and the floating portion 142 are installed in the first cabinet 40, such as Figure 1 As shown, the first cabinet 40 is a sealed cabinet filled with lubricant. The lubricant prevents direct contact and friction between the slider and the chute, and between the first gear 1411 and the second gear 1412, thereby reducing energy loss and wear, and improving the operating efficiency and life of the mechanical components.

[0092] In one embodiment, motor oil is used as the lubricant.

[0093] In some embodiments, the release mechanism 20 is disposed above the feeding mechanism 10 along the first direction 700. Figure 5 As shown, the release mechanism 20 includes a release motor 21, a mechanical cam 22, and a mounting base 23. The mounting base 23 includes a base body 231 and a first fixed shaft 232, wherein the base body 231 is rotatably connected to the first fixed shaft 232. The mechanical cam 22 is sleeved on and fixedly connected to the release motor output shaft 211, and the power transmission shaft is fixedly connected to the base body 231 via a bearing.

[0094] When the release command is received, the release motor 21 drives the mechanical cam 22 to rotate a first preset angle α1. During this process, the diameter of the mechanical cam 22 gradually increases, thereby pushing the base body 231 to rotate around the first fixed axis 232, and then driving the second driving wheel 13 to move from the clamping position to the release position.

[0095] When receiving the clamping instruction, the release motor 21 drives the mechanical cam 22 to rotate to the second preset angle α2. During this process, the diameter of the mechanical cam 22 gradually decreases, and the base body 231 rotates around the first fixed axis 232 under the action of its own gravity, thereby driving the second driving wheel 13 to return from the release position to the clamping position.

[0096] In some embodiments, α2=-α1.

[0097] For example, Figure 7 As shown, upon receiving a release command, the release motor 21 drives the mechanical cam 22 to rotate counterclockwise by β. During this process, the diameter of the mechanical cam 22 gradually increases, thereby driving the base body 231 to rotate counterclockwise around the first fixed axis 232, thereby driving the second driving wheel 13 to move from the clamping position to the release position. Upon receiving a clamping command, the release motor 21 drives the mechanical cam 22 to rotate clockwise by β. During this process, the diameter of the mechanical cam 22 gradually decreases. The base body 231 rotates clockwise around the first fixed axis 232 under the action of its own gravity, thereby driving the second driving wheel 13 to return from the release position and remain in the clamping position.

[0098] In some embodiments, the mounting base 23 further includes a second roller 2314, such as Figure 5 As shown, the second roller 2314 is located directly above the mechanical cam 22 along the first direction 700 and abuts against the mechanical cam 22. Figure 6 and Figure 7 shown.

[0099] High-speed feeding equipment operates at a rapid pace, with each feeding cycle measured in milliseconds. Each feeding cycle involves a clamping and a releasing action, so the contact point between the base body 231 and the mechanical cam 22 is susceptible to wear. To address this issue, the base body 231 of this embodiment is equipped with a second roller 2314. Since the second roller 2314 can rotate along its central axis, it prevents the second roller 2314 from contacting and being subjected to force at the same location on the mechanical cam 22, significantly reducing wear on the base body 231.

[0100] In some embodiments, the mounting base 23 includes a first plate 2311, a second plate 2312, and a third plate 2313 connected between the first plate 2311 and the second plate 2312, which are spaced apart along the first direction 700. The second roller 2314 is mounted on the first plate 2311, the power transmission shaft (15) is fixedly connected to the second plate 2312 via a bearing, and the first fixed shaft 232 is disposed on the second plate 2312 and is close to the third plate 2313. Figure 5 shown.

[0101] In some embodiments, as Figure 6 As shown, when the second driving wheel 13 is located at the clamping position, the plane where the central axis of the first fixed shaft 232 and the power transmission shaft 15 are located is perpendicular to the first plane.

[0102] In some embodiments, the feeding device further includes an airbag 30 , which is mounted on the second plate 2312 .

[0103] As mentioned above, during the clamping process, the base body 231 must rely on its own gravity to rotate around the first fixed axis 232. This method provides a relatively small force, so the second driving wheel 13 takes a long time to move to the clamping position, which cannot meet the requirements of high-speed feeding. To solve this technical problem, this embodiment provides an airbag 30 on the end of the second plate 2312 away from the first fixed axis 232. The thrust generated by the airbag 30 serves as an additional power source to assist the base body 231 in rotating around the first fixed axis 232, thereby accelerating the movement of the second driving wheel 13 to the clamping position. By providing the airbag 30 as an auxiliary power source on the third plate 2313, the problem of insufficient rotational power of the base body 231 due to relying on its own gravity can be effectively solved, and the speed at which the second driving wheel 13 moves to the clamping position can be increased, thereby meeting the requirements of high-speed feeding.

[0104] In some embodiments, to facilitate securing the feeding mechanism 10 and the release mechanism 20, the base of the feeding device includes a first vertical plate 51 and a second vertical plate 52 spaced apart along the direction of the feeding motor output shaft 111. The first vertical plate 51 is fixedly connected to the feeding motor 11 and the release motor 21. The second vertical plate 52 is disposed between the floating portion 142 and the mounting base 23 and is fixedly connected to the first cabinet. A bottom plate 53, a material loading platform 55, and a third plate 2313 are sequentially disposed between the first vertical plate 51 and the second vertical plate 52 along the first direction 700. A top plate 54 is disposed above the airbag 30. The bottom plate 53, the material loading platform 55, and the top plate 54 are fixedly connected to the first vertical plate 51 and the second vertical plate 52, respectively.

[0105] In some embodiments, the control system controls the action of the release motor 21 through a preset electronic cam curve, wherein the horizontal axis of the electronic cam curve represents the position of the main shaft of the control system, and the vertical axis represents the position of the release motor shaft.

[0106] Figure 8 901 exemplifies an electronic cam curve, where point q1 is the release start point, point q2 is the release end point, point q3 is the clamping start point, and point q4 is the clamping end point. As can be seen from this electronic cam curve, the release motor 21 begins operating at point q1. When it reaches point q2, the second driving wheel 13 reaches the release position, at which point the release motor 21 stops operating. The release motor 21 then operates again at point q3, and the second driving wheel 13 returns to the clamping position at point q4, at which point the release motor 21 stops operating. As can be seen from this electronic cam curve, if the second device can only begin operating after the second driving wheel 13 reaches the release position, the operating range of the second device is between points q2 and q3. To maintain production cycle time, the release motor 21 needs to be released into position within a relatively short period of time. This results in very high acceleration during operation of the release motor 21, as shown in 901. This in turn causes the motor to overheat, making it impossible for the release motor 21 to operate stably under high production cycle times.

[0107] This application can solve this technical problem by setting a breakaway point on the electronic cam curve. Figure 8902 exemplarily shows an electronic cam curve based on this embodiment. As shown in 902, a first disengagement point P2 is also provided between the release start point P1 and the release end point P3 of the electronic cam curve; when the release motor 21 runs to the first disengagement point P2, although the second driving wheel 13 has not yet reached the release position, it has completed the initial disengagement from the material. After the control system obtains that the shaft of the release motor 21 has reached the first disengagement point P2, it will immediately send corresponding action instructions to the downstream processing equipment. These instructions include adjusting the position of the material, fixing the material, and other preparatory work before cutting or stamping to ensure that the material and the downstream processing equipment are adjusted to a state suitable for processing before the second driving wheel 13 reaches the release position (the shaft of the release motor 21 runs to point P3). As can be seen from 902, this embodiment greatly reduces the acceleration of the release motor 21 during operation, thereby avoiding overheating of the motor, thereby ensuring the stable operation of the release motor 21 under high production rhythm.

[0108] In some embodiments, a second disengagement point P4 is further provided between the clamping start point P3 and the clamping end point P5 of the electronic cam curve. In one feeding processing cycle, the downstream equipment can only operate within the range from P2 to P4.
