[0025] Example 1

[0026] A temporary storage mechanism for material strip tails in a preferred embodiment of the present invention, as shown in Figures 1-2, includes a temporary storage box 10 with a built-in temporary storage cavity; a material strip channel 11 is provided at the upper end of the temporary storage box 10 for the material supply strip 01 to pass through; the material strip channel 11 is connected to the temporary storage cavity; the temporary storage mechanism cooperates with an external material retracting and releasing component to pull the material strip 01 to move in the material strip channel 11; the temporary storage mechanism also includes a material pressing component 30 for guiding the material strip 01 in the material strip channel 11 into the temporary storage cavity.

[0027] The structure design of the temporary storage mechanism for the tail of the material strip is ingenious. The material strip is driven to move in the material strip channel on the temporary storage box through the material pulling component, and then the material strip in the material strip channel is pressed toward the temporary storage cavity below the material strip channel through the material pressing component, thereby bringing the tail of the material strip into the temporary storage box for temporary storage. Not only is the space utilization rate high, but it also achieves the purpose of automatic caching of the tail of the material. During the caching process of the tail of the material, there is no need for manual pulling and sorting of the material, which can well solve the problem of random scattering and manual trampling of the tail of the material.

[0028] Furthermore, the pressing assembly 30 includes a pressing plate 31 adapted to the material strip channel 11, and a lifting assembly 32 that longitudinally drives the pressing plate 31 toward or away from the material strip channel 11; the thickness of the pressing plate 31 is not greater than the width of the material strip channel 11; the material strip tail storage mechanism also includes a photoelectric sensor that detects whether the material strip is in the material strip channel. When the photoelectric sensor detects the presence of material strip in the material strip channel, it sends a signal to the lifting assembly, and the lifting assembly drives the pressing plate downward through the material strip channel toward the temporary storage cavity, and then brings the material strip in the material strip channel into the temporary storage cavity, thereby realizing automatic caching of the tail material, and the operation is simple; wherein, the lifting assembly 32 includes a Z-axis slide rail, a slider slidably connected to the Z-axis slide rail, and a driving motor that drives the slider to move along the Z-axis slide rail, and the slider is fixedly connected to the pressing plate through a connecting bracket; optionally, the lifting assembly can also be a linear module or linear screw motor that drives the pressing plate to rise and fall in the prior art, or it can be other structures that can drive the pressing plate to rise and fall in the prior art. The above all fall within the scope of protection of the present utility model and will not be repeated here.

[0029] Furthermore, the pressing assembly 30 further includes a material moving assembly 33 that drives the lifting assembly 32 and the pressing plate 31 to move laterally toward or away from the temporary storage box 10 ; the material moving assembly 33 is located on one side of the temporary storage box 10 . As shown in Figure 3, the material moving assembly 33 includes a rotating bearing seat 331, a connecting arm 332 and a first driving mechanism arranged above the material belt channel 11; one end of the connecting arm 332 is fixedly connected to the rotating bearing seat 331, and the other end is fixedly installed with the lifting assembly 32 and the pressure plate 31; the first driving mechanism drives the rotating bearing seat 331 to rotate axially, so that the connecting arm 332 drives the pressure plate 31 to move above the material belt channel 11 with the rotating bearing seat 331 as the center of the circle, wherein the rotation angle of the connecting arm 332 is not greater than 90°; in one embodiment, the first driving mechanism includes a driven wheel 333 fixedly sleeved on the rotating bearing seat 331, a first rotating motor 334 and a synchronous belt 335; a driving wheel 336 is fixedly sleeved on the output shaft of the first rotating motor 334; the driving wheel 336 and the driven wheel 333 are connected by a synchronous belt 335. Optionally, the first driving mechanism can also be a rotating motor or other rotatable structure that drives the rotating bearing seat to rotate in the prior art.

[0030] Furthermore, the temporary storage mechanism for the tail material of the material strip 01 also includes a second driving mechanism 40 for driving the temporary storage box 10 to rotate; the second driving mechanism includes a rotating motor in the prior art, and can also be other structures in the prior art, which will not be repeated here.

[0031] In the initial state, the temporary storage box and the pressure plate are perpendicular to the transport direction of the material belt. When working, the second driving mechanism drives the temporary storage box to rotate clockwise until it is parallel to the transport direction of the material belt, and then the driving mechanism drives the pressure plate to rotate clockwise until it is parallel to the material belt channel on the temporary storage box, so that the pressure plate can guide the material belt in the material belt channel into the temporary storage cavity; when not working, the driving mechanism drives the pressure plate to rotate counterclockwise to the origin, and then the second driving mechanism drives the temporary storage box to rotate counterclockwise to the origin, so that the pressure plate and the temporary storage plate can be flexibly stored and the space can be reasonably used.

[0032] Furthermore, the two ends of the material belt channel 11 are respectively the feed port 111 and the discharge port 112; the material receiving and unloading component 20 includes a driven roller arranged on one side of the feed port 111, an active roller arranged on one side of the discharge port 112 and a second rotating motor driving the active roller to rotate in the transportation direction of the material belt 01; the transmission surface of the driven roller, the transmission surface of the material belt channel 11 and the transmission surface of the active roller are all located in the same plane.

[0033] Furthermore, the temporary storage box 10 includes two oppositely arranged vertical plates 101, a front side plate, a rear side plate and a bottom plate; the two vertical plates 101, the front side plate, the rear side plate and the bottom plate are mutually enclosed to form a temporary storage cavity for stacking a single material strip 01 from bottom to top; the material strip is not easy to get knotted when being cached, and the upper end of the two vertical plates 101 is located on one side of the material strip channel 11 and is provided with an outward-extending inclined baffle 102 to prevent the material strip 01 from moving out of the material strip channel 11, so that the material strip is in a predetermined track, which facilitates the pressing plate to accurately press the material strip into the temporary storage cavity.

[0034] Example 2

[0035] This embodiment provides a temporary storage mechanism for material strip tails. The similarities with the first embodiment are not repeated here, and the differences are shown in FIG4 . The material moving assembly 33 includes a mounting frame 337 movably arranged on one side of the temporary storage box 10, and a linear module 338 that drives the mounting frame 337 away from or close to the temporary storage box 10. The lifting assembly and the pressure plate are both installed on the side surface of the mounting frame facing the temporary storage box. When working, the linear module drives the mounting frame to move to the top of the temporary storage box, so that the pressure plate and the feed channel of the temporary storage box are located in the same vertical plane, so that the subsequent lifting assembly drives the pressure plate to press the material strip in the feed channel on the temporary storage box into the temporary storage cavity.
