[0032] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0033] like Figure 1 As shown, in one embodiment of this utility model, the material storage device for lunchbox production includes a frame 1, a motion drive component 2, and at least two clamping mechanisms 6. The mounting end of the motion drive component 2 is connected to the frame 1. Each clamping mechanism 6 includes a rotation drive component 3 and a clamping component 4. The mounting end of the rotation drive component 3 is connected to the movable end of the motion drive component 2. The mounting end of the clamping component 4 is connected to the movable end of the rotation drive component 3. A clamping gap 5 is provided between two adjacent clamping components 4. The outer surface of each clamping component 4 is provided with an abutment slope 401. Wherein, as... Figure 1 As shown, there are two clamping mechanisms 6, which are arranged side by side on the motion drive component 2.

[0034] The technical solution of this utility model places the paper roll inside the clamping gap, and combines the clamping component and its abutting inclined surface to clamp and limit the central shaft part and side end surface of the roll, thereby helping to ensure the stability and smoothness of rotating feeding. In addition, since the winding tightness of the roll will decrease and a channel will be generated in the middle as the roll is rotated and unloaded, this structure also combines the driving of the motion drive component in the space of the feeding station, so that the clamping component moves along the space, so that the relative movement of two adjacent clamping components reduces the clamping gap as the roll is rotated and unloaded, thereby gradually increasing the clamping stress on the roll; thus ensuring the stability and smoothness of rotating feeding.

[0035] Specifically, in some implementations, such as Figure 1 As shown, the rotation drive component 3 includes a rotation drive motor 31 and a bracket 32; the bracket 32 ​​is connected to the movable end of the motion drive component 2; the mounting end of the rotation drive motor 31 is connected to the bracket 32; and the movable end of the rotation drive motor 31 is connected to the clamping component 4. The rotation drive motor 31 is a stepper motor to achieve the rotation speed and frequency of the clamping component 4, thereby ensuring the stability and smoothness of the rotational feeding.

[0036] Specifically, in some implementations, such as Figure 1 and 2 As shown, the abutting inclined surface 401 includes a first inclined surface 402 and a second inclined surface 403; the clamping component 4 includes a first clamping cylinder 41, a second clamping cylinder 42, and a limiting member 43 connected in sequence; the limiting member 43 is connected to the movable end of the rotation drive component 3 (rotation drive motor 31); the first inclined surface 402 is disposed on the outer surface of the first clamping cylinder 41; the second inclined surface 403 is disposed on the outer surface of the second clamping cylinder 42; and the angle α between the first inclined surface 402 and its horizontal plane and the angle β between the second inclined surface 403 and its horizontal plane satisfy: α < β. That is, by first abutting and limiting the outer surface of the winding body formed by the paper sheet, and then abutting and limiting the outer surface of the winding body formed by the paper sheet as the rotation feeding proceeds, the clamping stress on the winding body is gradually increased; thereby ensuring the stability and smoothness of the rotation feeding.

[0037] Specifically, in some implementations, such as Figure 2 and 3 As shown, the first clamping cylinder 41 includes a first clamping section 412 and a second clamping section 413 connected to each other; the angle α between the first inclined surface 402 on the first clamping section 412 and its horizontal plane is equal to the angle α between the first inclined surface 402 on the second clamping section 413 and its horizontal plane; the second clamping section 413 is connected to the second clamping cylinder 42; and the thickness of the first clamping section 412 is less than the thickness of the second clamping section 413. This structure forms a stepped structure through the first clamping section 412 and the second clamping section 413 to improve the step's contact and limiting effect on the wound body at the connection point, thereby ensuring the stability and smoothness of the rotating feeding.

[0038] Specifically, in some implementations, such as Figure 2 As shown, the outer surface of the first clamping cylinder 41 (including the first clamping section 412 and the second clamping section 413) is provided with at least one first protrusion 411; the first protrusion 411 extends along the clamping gap 5 toward the rotation drive component 3; and the thickness h1 of the first protrusion 411 satisfies: 3mm≤h1≤10mm; preferably h1=5mm. The first protrusion 411 is selected as a first protrusion with an arc-shaped cross-section. This structure increases the contact stress on the wound body through the first protrusion 411, thereby ensuring the stability and smoothness of the rotational feeding.

[0039] Specifically, in some implementations, such as Figure 2As shown, the outer surface of the second clamping cylinder 42 is provided with at least one second protrusion 421; the second protrusion 421 extends along the clamping gap 5 toward the rotation drive component 3; and the thickness h1 of the second protrusion 421 satisfies: 5mm≤h1≤12mm; preferably h2=8mm. The second protrusion 421 is selected as a second protrusion with an arc-shaped cross-section. This structure, through the second protrusion 421, increases the contact stress on the wound body, thereby ensuring the stability and smoothness of the rotational feeding.

[0040] Specifically, in some implementations, such as Figure 2 and 3 As shown, the second clamping cylinder 42 includes a housing 422 and an assembly plate 424; the housing 422 has an installation cavity 423; a second inclined surface is provided on the outer surface of the housing 422; one end of the first clamping cylinder 41 is engaged with one side opening of the installation cavity 423; the assembly plate 424 is connected to the other side opening of the installation cavity 423; and a limiting member 43 is connected to the side surface of the assembly plate 424 away from the installation cavity 423. The assembly plate 424 is detachably connected to the other side opening of the installation cavity 423 by fixing screws. This structure, with its hollow and split second clamping cylinder 42, ensures the installation stability of the first clamping cylinder 41 and the contact stress on the wound body, thereby ensuring the stability and smoothness of the rotating feeding.

[0041] Specifically, in some implementations, such as Figure 3 As shown, at least one elastic element 414 is provided on the side of the first clamping cylinder 41 facing the second clamping cylinder 42; the elastic element 414 is disposed inside the mounting cavity 423; and a mounting plate 415 is provided on the side of the elastic element 414 away from the first clamping cylinder 41; an assembly plate 424 abuts against the mounting plate 415. The elastic element 414 is a spring; and the length L of the elastic element 414 satisfies: 1cm ≤ L ≤ 3cm; preferably 3cm. The assembly plate 424 is a stepped assembly plate; that is, two T-shaped sections. In other words, this structure, through the micro-compression deformation of the elastic element 414, can increase the compressive limiting stress on the wound body, ensuring its assembly stability and adaptability to different types of wound bodies; thereby ensuring the stability and smoothness of the rotating feeding process.

[0042] Specifically, in some implementations, such as Figure 2 and 3As shown, the limiting component 43 includes a limiting plate 431 and a mounting shaft 432; the limiting plate 431 is connected to the second clamping cylinder 42 (middle assembly plate 424); one end of the mounting shaft 432 is connected to the limiting plate 431; the other end of the mounting shaft 432 is connected to the rotation drive component 3 (the main shaft of the middle rotation drive motor 31). This structure can ensure the assembly stability of the first clamping cylinder 41 and the second clamping cylinder 42, thereby ensuring the stability and smoothness of rotational feeding.

[0043] Specifically, in some implementations, such as Figure 1 and 4 As shown, the motion drive component 2 includes a height adjustment assembly 21, a mounting frame 22, and a horizontal lateral movement adjustment assembly 23. The mounting end of the height adjustment assembly 21 is connected to the frame 1; the movable end of the height adjustment assembly 21 is connected to the mounting frame 22; the mounting end of the horizontal lateral movement adjustment assembly 23 is connected to the mounting frame 22; and the movable end of the horizontal lateral movement adjustment assembly 23 is connected to the rotation drive component 3 (middle support 32). This structure improves the speed and convenience of adjusting the height and horizontal position of the clamping component 4 by driving the height direction (vertical direction) of the height adjustment assembly 21 and driving the horizontal direction (left-right direction) of the horizontal lateral movement adjustment assembly 23, thereby adapting to more winding bodies of different specifications; and ensuring the stability and smoothness of rotational feeding.

[0044] Specifically, in some implementations, such as Figure 4 As shown, the height adjustment assembly 21 includes a height adjustment cylinder 211 and a connecting shaft 212; the height adjustment cylinder 211 is connected to the frame 1 and to one end of the connecting shaft 212; the other end of the connecting shaft 212 is connected to the mounting bracket 22. This structure ensures the speed and convenience of adjusting the height position of the clamping component 4 through the reciprocating motion of the height adjustment cylinder 211.
