[0002] The processing of transmission chains mainly includes raw material preparation, chain plate production, heat treatment, assembly inspection, surface treatment, packaging and shipment. Among them, assembly inspection is an important link to ensure the quality of the chain during the processing. Specifically, after the heat-treated chain plates are assembled according to certain specifications and sequence, the chain needs to be inspected, including appearance inspection, dimensional measurement and tensile testing, to ensure that the assembly quality and performance of the chain meet the requirements.

[0003] Among them, when performing a visual inspection on the assembled transmission chain, the existing technology mostly adopts a manual full inspection method to complete it.

[0040] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0041] like Figure 1-Figure 9 As shown, the present embodiment provides a feeding device for processing a transmission chain, comprising: a base 10, a mounting frame 20, the mounting frame 20 is fixedly mounted on the upper surface of the base 10, a support frame 30, slidably arranged on the inner side of the mounting frame 20, a baffle rod 40, arranged on the mounting frame 20, and at least one bearing assembly 50, arranged on the support frame 30; the bearing assembly 50 comprises a pair of transverse axes 51 rotatably mounted on the support frame 30, a bearing plate 52 is fixedly connected between the pair of transverse axes 51, and the bearing plate 52 is inclined at a certain angle, at least one slide plate 53 is slidably arranged on the bearing plate 52, an arc-shaped baffle plate 54 is fixedly connected to the upper side of the slide plate 53, a force-bearing plate 55 is rotatably connected to the side of the bearing plate 52 close to the baffle rod 40, and a moving assembly 60 is arranged on the base 10, and is used to drive the support frame 30 to reciprocate in the vertical direction.

[0042] The working principle and beneficial effects of the above technical solution are:

[0043] First, the assembled transmission chain is coiled into a disc shape and stacked on the corresponding slide plate 53 in sequence, so that the disc-shaped transmission chain and the arc-shaped baffle plate 54 are offset against each other, and the extrusion force between the transmission chains and the force between the transmission chain and the arc-shaped baffle plate 54 are used to maintain stability after stacking.

[0044] Next, the device is moved to a position close to the inspection table, and the position of the device is adjusted so that the edges of the device and the inspection table in the length or width direction remain parallel, and the blocking rod 40 is in a position parallel to or higher than the table surface. Then, the moving assembly 60 is started to drive the support frame 30 to move vertically upward, so that the force-bearing plate 55 on the uppermost supporting plate 52 contacts and squeezes the blocking rod 40. At this time, the side of the force-bearing plate 55 close to the supporting plate 52 is supported by the lower surface of the supporting plate 52, so that it cannot rotate. Then, when the force-bearing plate 55 contacts the blocking rod 40 from bottom to top, it drives the uppermost supporting plate 52 to rotate with the horizontal axis 51 as the center of the circle, and lifts the side of the slide plate 53 away from the force-bearing plate 55, so that it slides relative to the supporting plate 52 under the action of gravity, forming a slideway between the supporting plate 52 and the inspection table, and the transmission chain slides down to the table surface of the inspection table under the action of gravity.

[0045] At the same time, the support frame 30 continues to rise until the force-bearing plate 55 and the blocking rod 40 are separated, completing the loading of the first layer of the supporting plate 52. When it is necessary to continue loading, the moving assembly 60 is controlled to drive the support frame 30 to continue to move upward until the remaining layers of the supporting plates 52 below repeat the above process in sequence to complete the loading work.

[0046] Finally, the control moving component 60 drives the support frame 30 to move downward, and the force-bearing plate 55 and the slide plate 53 on the supporting plate 52 contact the blocking rod 40 from top to bottom. At this time, there are no obstacles on the rotation path of the force-bearing plate 55, and it can rotate freely, so that the blocking rod 40 can smoothly separate from the force-bearing plate 55 and contact the slide plate 53, thereby driving the slide plate 53 and the corresponding supporting plate 52 to rotate in the opposite direction, so that the supporting plate 52 is reset to the initial angle. At the same time, the slide plate 53 slides in the direction close to the corresponding supporting plate 52 under the action of gravity, and also moves to the initial position, so that the device can be reused.

[0047] It should be noted that chains that are relatively smooth overall, such as agricultural machinery transmission chains and motorcycle transmission chains, can be directly stacked on the slide plate 53. For special-shaped chains, it is necessary to pay attention to the placement direction and place the smoother side on the slide plate 53 to avoid excessive wear or scratching of the slide plate 53, which would affect the normal use of the device.

[0048] The present embodiment adopts the technical means of cooperating the bearing assembly 50 and the blocking rod 40. When feeding is needed, first of all, the electric trolley 90 loaded with the chain to be inspected is moved to a position close to the edge of the inspection table. Then, the moving assembly 60 is used to drive the support frame 30 to move upward, and the blocking rod 40 blocks the force plate 55, so that the bearing plate 52 rotates, and the chains stacked on the plate slide down to the table surface under the action of gravity. The operation is simple and labor-saving, which overcomes the technical problem of time-consuming and labor-intensive feeding in the prior art, and thus achieves the technical effect of improving feeding efficiency.

[0049] The present embodiment also adopts the technical means of cooperating the inclined supporting plate 52 and the arc-shaped baffle 54. Under the action of gravity, the stacked transmission chains are tilted to one side and pressed against the inner wall of the arc-shaped baffle 54, so that although they are simply coiled up, they rarely fall over during feeding, thereby improving the stability of the device during feeding.

[0050] In a specific embodiment, a curved rubber strip 56 is fixedly mounted on the upper surface of the slide plate 53 .

[0051] The working principle and beneficial effects of the above technical solution are as follows: the arc-shaped rubber strip 56 can not only remind the staff to place the transmission chain to be inspected in the correct position, but also when the supporting plate 52 rotates toward the direction close to the inspection table surface, the arc-shaped rubber strip 56 can provide resistance to the transmission chain, thereby preventing the transmission chain from sliding down too fast, causing it to slide off before the slide plate 53 is moved down to its full position, and falling to the ground, causing unnecessary damage.

[0052] In a specific embodiment, the number of the bearing assemblies 50 is set to three, and the number of the slide plates 53 on each bearing plate 52 is set to three.

[0053] The working principle and beneficial effects of the above technical solution are as follows: It should be noted that the number of the bearing assembly 50 and the slide plate 53 includes but is not limited to three, and can be flexibly set according to actual production needs.

[0054] In a specific embodiment, the inclination angle of the carrying plate 52 is set between 5° and 15°.

[0055] The working principle and beneficial effects of the above technical solution are as follows: the inclination angle of the supporting plate 52 should not be too small. If it is too small, the supporting effect of the arc-shaped baffle 54 will be limited. If a large bump is encountered during feeding, the transmission chain stacked on the upper layer will easily slide to the other side under the reaction force of the arc-shaped baffle 54. If it is too large, it will easily fall to the other side when encountering a large bump. Therefore, it is more appropriate to set the inclination angle between 5° and 15°.

[0056] In a specific embodiment: a side of the bearing plate 52 away from the arc-shaped baffle plate 54 is fixedly connected to a limiting plate 57 , and a transverse plate 58 is detachably mounted on the mounting frame 20 .

[0057] The working principle and beneficial effects of the above technical solution are as follows: the horizontal plate 58 abuts against the limit plate 57, so that the supporting plate 52 can be stably maintained at a certain inclination angle. At the same time, the horizontal plate 58 can be disassembled and installed at different heights to cooperate with the supporting plate 52 to adjust the inclination angle, thereby further improving the practicality of the device.

[0058] In a specific embodiment: the moving component 60 includes a pair of U-shaped plates 61 slidably arranged on the mounting frame 20, each U-shaped plate 61 is fixedly connected to the support frame 30, and a slide groove for the U-shaped plate 61 to slide is opened on the mounting frame 20. A pair of threaded rods 62 are rotatably connected to the base 10, and a pair of mounting blocks 63 are fixedly connected to the mounting frame 20. The upper end of each threaded rod 62 is rotatably connected to the corresponding mounting block 63, and the threaded rod 62 is threadedly connected to the corresponding U-shaped plate 61. Each threaded rod 62 extends to the rod body on the lower side of the base 10 and is fixedly connected to a synchronous wheel 64. The two synchronous wheels 64 are matched through a synchronous belt 65 for transmission, and a driving device for driving one of the threaded rods 62 to rotate is provided on the lower side of the base 10.

[0059] The working principle and beneficial effects of the above technical solution are as follows: the driving device drives the corresponding threaded rod 62 to rotate, and under the cooperation of the synchronous wheel 64 and the synchronous belt 65, the two threaded rods 62 rotate synchronously, thereby driving the two U-shaped plates 61 and the mounting frame 20 to slide relative to each other, so that the support frame 30 rises or falls.

[0060] In a specific embodiment: a limiting assembly 70 is set on the lower side of the slide plate 53, and the limiting assembly 70 includes a pair of annular blocks 71 fixedly connected to the lower side of the slide plate 53, and a limiting groove is opened at the corresponding position on the supporting plate 52, and a limiting rod 72 is fixedly connected in the limiting groove, and each annular block 71 is slidably connected to the corresponding limiting rod 72.

[0061] The working principle and beneficial effects of the above technical solution are as follows: when the slide plate 53 moves, it drives the annular block 71 to move synchronously, so that the annular block 71 and the corresponding limiting rod 72 slide relative to each other. At the same time, the slide plate 53 is restricted in its movement trajectory by the limiting rod 72 and can only move back and forth along the axial direction of the limiting rod 72.

[0062] In a specific embodiment: an adjustment component 80 is provided on the mounting frame 20, and the adjustment component 80 includes a pair of slide bars 81 slidably arranged inside the symmetrical plate body of the mounting frame 20, and a vertical groove is opened inside the mounting frame 20 for the corresponding slide bars 81 to slide up and down, and the opposite sides of the two slide bars 81 are fixedly connected to the blocking rod 40, and the upper side of the symmetrical plate body of the mounting frame 20 is rotatably provided with threaded rods 82, each threaded rod 82 is threadedly connected to the corresponding slide bar 81, and the upper end of the threaded rod 82 is fixedly connected to a turntable 83.

[0063] The working principle and beneficial effects of the above technical solution are: rotating the two turntables 83 at the same time drives the corresponding threaded rod 82 to rotate, and then drives the slide bar 81 to move up or down in the corresponding vertical groove, so that the height of the blocking rod 40 can be adjusted to adapt to inspection tables of different heights.

[0064] This embodiment adopts the technical means of cooperating the adjustment component 80 and the blocking rod 40, and uses the adjustment component 80 to drive the blocking rod 40 to move back and forth in the vertical direction, so that the device can adapt to inspection tables of different heights, expand the adaptation range of the device, and further improve the practicality of the device.

[0065] In a specific embodiment: an electric trolley 90 is arranged on the lower side of the base 10, an electric control box 91 is installed on the handle of the electric trolley 90, the driving device is configured as a servo motor 66, the servo motor 66 is fixedly installed on the lower side of the electric trolley 90, and the electric control box 91 is electrically connected to the servo motor 66.

[0066] The working principle and beneficial effects of the above technical solution are: by pressing the corresponding button on the electric control box 91, the electric trolley 90 can be controlled to move forward, or the servo motor 66 can be controlled to rotate forward or reverse, thereby simplifying the operation.

[0067] In a specific embodiment: a dustproof plate 84 is hinged on the upper side of the mounting frame 20, and a mounting groove for the turntable 83 to be embedded is opened on the dustproof plate 84.

[0068] The working principle and beneficial effects of the above technical solution are as follows: the dustproof plate 84 can prevent a large amount of dust from accumulating on the surface of the transmission chain when the transmission chain has not entered the feeding process.

[0069] Working principle:

[0070] First, the assembled transmission chain is coiled into a disc shape and stacked on the corresponding slide plate 53 in sequence, so that the disc-shaped transmission chain and the arc-shaped baffle plate 54 are offset against each other, and the extrusion force between the transmission chains and the force between the transmission chain and the arc-shaped baffle plate 54 are used to maintain stability after stacking.

[0071] Next, the electric trolley 90 is used to move the device to a position close to the inspection table, and the position of the device is adjusted so that the edges of the device and the inspection table in the length or width direction remain parallel, and the blocking rod 40 is in a position parallel to or higher than the table surface. Then, the servo motor 66 is started to drive the corresponding threaded rod 62 to rotate. Under the cooperation of the synchronous wheel 64 and the synchronous belt 65, the two threaded rods 62 rotate synchronously, thereby driving the two U-shaped plates 61 and the mounting frame 20 to slide relative to each other, driving the support frame 30 to move vertically upward, so that the load-bearing plate on the uppermost load-bearing plate 52 is 55 contacts and squeezes the blocking rod 40. At this time, the side of the force-bearing plate 55 close to the supporting plate 52 is resisted by the lower surface of the supporting plate 52, making it unable to rotate. As a result, when the force-bearing plate 55 contacts the blocking rod 40 from bottom to top, it drives the uppermost supporting plate 52 to rotate around the horizontal axis 51 as the center of the circle, and lifts the side of the slide plate 53 away from the force-bearing plate 55. The limit plate 57 and the corresponding horizontal plate 58 are separated, so that the slide plate 53 slides relative to the supporting plate 52 under the action of gravity, forming a slideway between the supporting plate 52 and the inspection table, and the transmission chain slides down to the table surface of the inspection table under the action of gravity.

[0072] At the same time, the support frame 30 continues to rise until the force-bearing plate 55 and the blocking rod 40 are separated, completing the loading of the first layer of the supporting plate 52. When it is necessary to continue loading, the moving assembly 60 is controlled to drive the support frame 30 to continue to move upward until the remaining layers of the supporting plates 52 below repeat the above process in sequence to complete the loading work.

[0073] Finally, the control moving component 60 drives the support frame 30 to move downward, and the force-bearing plate 55 and the slide plate 53 on the supporting plate 52 contact the blocking rod 40 from top to bottom. At this time, there are no obstacles on the rotation path of the force-bearing plate 55, and it can rotate freely, so that the blocking rod 40 can smoothly separate from the force-bearing plate 55 and contact the slide plate 53, thereby driving the slide plate 53 and the corresponding supporting plate 52 to rotate in the opposite direction, so that the supporting plate 52 is reset to the initial angle. At the same time, the slide plate 53 slides in the direction close to the corresponding supporting plate 52 under the action of gravity, and also moves to the initial position, so that the device can be reused.

[0074] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
