The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Firstly, please refer to Figs. 1-3 As shown, in this embodiment, a compatible material strip temporary storage bin includes a fixing member 10, a movable plate 20, and at least one set of driving components 30, wherein: the fixing member 10 includes a base plate 100 and a side plate 101, the side plate 101 is disposed on the outer edge of the base plate 100 and extends toward the movable plate 20, and the movable plate 20 can move along a first direction ( Fig. 1 The movable plate 20, the substrate 100, and the side plate 101 are arranged on one side of the substrate 100 (in the X direction) close to or away from the substrate 100. The movable plate 20, the substrate 100, and the side plate 101 are combined to form a storage cavity for storing the material strip. The drive assembly 30 is disposed on the substrate 100. The drive end of the drive assembly 30 is connected to the movable plate 20. The drive assembly 30 is configured to drive the movable plate 20 close to or away from the substrate 100 to adjust the width of the storage cavity.

[0030] As can be seen, through the cooperation of the substrate 100, the movable plate 20 and the driving component 30, the driving component 30 drives the movable plate 20 to move closer to or further away from the substrate 100, so as to adjust the width of the storage cavity, thereby realizing the storage of material strips of different specifications and achieving good compatibility.

[0031] In one implementation, two sets of drive components 30 are provided, and the two sets of drive components 30 are spaced apart along the height direction on the side of the substrate 100 away from the movable plate 20.

[0032] It can be seen that by setting two sets of drive components 30, driving force can be provided from different height positions, avoiding the uneven force and unstable driving that may occur when relying on a single drive component, thus ensuring the stability of the movable plate 20 during the lateral movement.

[0033] In one embodiment, the opening of the storage cavity is set facing upward, and a guide roller 40 is rotatably provided at the first end of the opening. After the material belt passes through the upper roller surface of the guide roller 40, it is introduced into the storage cavity from the second end of the opening.

[0034] As can be seen, by setting the guide roller 40, the material belt is introduced into the storage cavity after passing through the guide roller 40, and the material is guided by rolling friction, which reduces the wear of the material belt while achieving the guiding.

[0035] In one embodiment, each drive assembly 30 includes a pitch-changing drive 31 and a transverse movement 32. The fixed end of the pitch-changing drive 31 is mounted on the substrate 100. The drive end of the pitch-changing drive 31 is connected to the first end of the transverse movement 32. The second end of the transverse movement 32 is fixedly connected to the movable plate 20. The pitch-changing drive 31 drives the transverse movement 32 to move closer to or away from the substrate 100, thereby causing the movable plate 20 to move closer to or away from the substrate 100, and thus adjusting the width of the material cavity.

[0036] Specifically, the variable pitch drive component 31 is a variable pitch electric cylinder.

[0037] As can be seen, the direct adjustment of the distance between the movable plate 20 and the base plate 100 is achieved through the cooperation of the variable pitch drive component 31 and the transverse movement component 32, providing a drive component 30 with a simple structure and easy operation.

[0038] In one embodiment, a guide member 11 extending toward the movable plate 20 is provided on the substrate 100, and a guide hole 21 is provided through the guide member 11 on the movable plate 20, through which the movable plate 20 passes.

[0039] As can be seen, by setting the guide 11 extending toward the movable plate 20, the movable plate 20 can move precisely with the cooperation of the guide 11 and the guide hole 21 during the process of the drive assembly 30 driving the movable plate 20 to move closer to or away from the substrate 100, thus ensuring the accuracy of the storage cavity width adjustment and making it more suitable for storing material strips of different specifications.

[0040] In one embodiment, a compatible material strip temporary storage bin further includes a first pressing assembly 50. The first pressing assembly 50 includes a pressing base 51, a first driving member 52, and a lifting pressing block 53. The pressing base 51 is fixedly disposed on the upper end of the base plate 100. The lifting pressing block 53 is movably disposed on the pressing base 51 and located at the second end of the opening. The bottom of the lifting pressing block 53 is provided with an arc surface 530. The fixed end of the first driving member 52 is mounted on the pressing base 51, and the driving end of the first driving member 52 is connected to the lifting pressing block 53. The first driving member 52 is configured to drive the lifting pressing block 53 to rise and fall, so that the lifting pressing block 53 rises to a high position or falls to a low position. When the lifting pressing block 53 is in the low position, the lifting pressing block 53 presses the material strip at the opening and guides the material strip into the storage cavity.

[0041] As can be seen, by driving the lifting block 53 to a low position through the first driving member 52, the material strip is pressed and guided into the storage cavity by the arc surface 530 at the bottom of the lifting block 53 at the opening, thus providing a first pressing component 50 with pressing and guiding functions.

[0042] In one embodiment, a transmission pair 54 is provided between the first driving member 52 and the lifting pressure block 53. The transmission pair 54 includes a transmission screw 540 and a nut 541. The transmission screw 540 is rotatably mounted on the pressure seat 51 along its own axis. The nut 541 is fixed on the lifting pressure block 53 and sleeved on the transmission screw 540. The driving end of the first driving member 52 is connected to the transmission screw 540. The first driving member 52 is configured to drive the transmission screw 540 to rotate along its own axis. The first driving member 52 drives the lifting pressure block 53 to rise and fall through the transmission cooperation of the transmission screw 540 and the nut 541.

[0043] As can be seen, through the cooperation of the transmission screw 540 and the nut 541, the first driving component 52 drives the transmission screw 540 to rotate along its own axis, effectively driving the lifting pressure block 53 to rise and fall, providing a transmission pair 54 with high transmission accuracy and high transmission efficiency.

[0044] Specifically, a guide pair 55 is provided between the lifting pressure block 53 and the pressure seat 51. The guide pair 55 includes a linear guide rail 550 and a slider 551. The linear guide rail 550 is fixed on the pressure seat 51 along the height direction, and the slider 551 is fixed on the lifting pressure block 53 and slidably sleeved on the linear guide rail 550.

[0045] Specifically, the first driving component 52 is a drive motor.

[0046] It can be seen that by setting the guide pair 55, the smoothness of the lifting pressure block 53 sliding on the pressure seat 51 is improved.

[0047] In one embodiment, the side plate 101 is integrated with the base plate 100, and the side plate 101 is configured as a flange around the base plate 100, with the movable plate 20 located within the area enclosed by the flange.

[0048] As can be seen, by combining the side plate 101 with the base plate 100, and setting the side plate 101 as a flange around the base plate 100, it can not only form a storage cavity with the movable plate 20 and the base, but also effectively limit the lateral displacement range of the movable plate 20 and prevent the movable plate 20 from shifting during movement.

[0049] In one embodiment, a second pressing assembly 60 is provided at the first end of the opening. The second pressing assembly 60 includes a second driving member 61 and a rotating baffle 62. The rotating baffle 62 is rotatably disposed on the substrate 100. The fixed end of the second driving member 61 is mounted on the substrate 100, and the driving end of the second driving member 61 is connected to the rotating baffle 62. The second driving member 61 is configured to drive the rotating baffle 62 to alternately rotate to a first position or a second position. When the rotating baffle 62 is in the first position, the rotating baffle 62 is located outside the opening. When the rotating baffle 62 is in the second position, the rotating baffle 62 rotates along a second direction (…). Fig. 1 It extends in the Y direction and is located between the guide roller 40 and the lifting pressure block 53, thereby limiting the jumping of the material belt located in the storage cavity.

[0050] As can be seen, by setting the rotating baffle 62, when the rotating baffle 62 is in the second position, the rotating baffle 62 is located between the guide roller 40 and the lifting pressure block 53, which realizes the limitation of the jumping of the material belt in the storage cavity during high-speed material collection, and prevents the material belt from jumping out of the storage cavity.

[0051] Specifically, a sensor 12 is provided on the substrate 100, and the sensor 12 is configured to detect whether there is a material strip at the second end of the opening.

[0052] As can be seen, by setting the sensor 12, the material strip at the opening can be detected, which further improves the automation level of the equipment.

[0053] Specifically, the second driving component 61 is a rotary cylinder.

[0054] Secondly, based on the aforementioned compatible material strip temporary storage bin, a material strip splicing and unsplitting machine is proposed, including the aforementioned compatible material strip temporary storage bin.

[0055] When the aforementioned compatible material strip temporary storage bin needs to store material strips of different widths: the variable pitch drive 31 drives the transverse movement 32 to approach or move away from the substrate 100, which in turn drives the movable plate 20 to approach or move away from the substrate 100 in sync. With the cooperation of the guide 11 and the guide hole 21, the movable plate 20 moves smoothly along the first direction, thereby realizing the adjustment of the width of the storage cavity to adapt it to the corresponding specification of material strip.

[0056] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
