The speed limiting assembly can apply a damping force to the material roll shaft in the opposite direction of the material roll discharge direction, thereby limiting the rotation speed of the material roll shaft in the material roll discharge direction, thereby avoiding the material roll shaft rotating too fast and causing the material to stack between the material roll shaft and the processing equipment.

[0008] Specifically, the coil shaft is perpendicular to the discharge direction of the material roll, the material roll is sleeved on the outer circumference of the coil shaft and can rotate with the coil shaft; the driving assembly includes a driving shaft coaxially arranged with the coil shaft, one end of the driving shaft is detachably connected to one end of the coil shaft, and the other end is away from the coil shaft, the driving shaft can drive the coil shaft to rotate in the opposite direction of the discharge direction of the material roll, and link the material roll on the coil shaft to rotate synchronously with the coil shaft, so that the material stacked between the coil shaft and the processing equipment is rewound onto the coil shaft, the stacked material is tensioned, and the material fed into the processing equipment remains flat, avoiding the subsequent press-formed material from wrinkling, breakage and other quality problems due to unevenness. In addition, the driving shaft can also drive the coil shaft to move along the axial direction of the coil shaft to adapt to coils with different axial lengths or adjust according to the distance between the support frames supporting the two ends of the coil shaft.

[0009] The speed limiting component includes a first speed limiting component and a second speed limiting component adapted to the first speed limiting component; wherein the first speed limiting component is rotatably arranged on one side of one end of the winding shaft, and the second speed limiting component is fixedly sleeved on the outer periphery of one end of the winding shaft, close to the first speed limiting component, the first speed limiting component and the second speed limiting component are adapted to engage with each other, and when the winding shaft rotates along the discharge direction of the material roll, the first speed limiting component and the second speed limiting component are adapted to engage with each other and rub against each other, and the first speed limiting component applies a damping force to the second speed limiting component in the opposite direction of the discharge direction of the material roll, and the damping force acts on the second speed limiting component and the winding shaft at the same time, thereby limiting the rotation speed of the winding shaft and the second speed limiting component in the discharge direction of the material roll, thereby avoiding the winding shaft from rotating too fast in the discharge direction, causing the material to stack between the winding shaft and the processing equipment.

[0010] According to another specific embodiment of the utility model, the embodiment of the utility model discloses an adjustable support mechanism for a material roll, a first speed limiting component includes a coaxially arranged damper and a first gear, a second speed limiting component includes a second gear fixedly sleeved on the outer periphery of one end of the winding shaft, and the first gear and the second gear are meshed with each other, when the winding shaft rotates along the discharge direction of the material roll, the second gear fixedly sleeved on the outer periphery of one end of the winding shaft rotates synchronously, and the coaxially arranged damper and the first gear apply a damping force opposite to the discharge direction of the material roll to the second gear through gear meshing, thereby limiting the rotation speed of the second gear and the winding shaft along the discharge direction of the material roll, and avoiding the material from stacking between the winding shaft and the processing equipment due to excessive rotation speed of the winding shaft.

[0011] In summary, the utility model provides an adjustable support mechanism for a material roll, which can realize the axial position adjustment and tension adjustment of the material roll wound on the material roll shaft. It includes a material roll shaft, a driving assembly and a speed limiting assembly arranged at one end of the material roll shaft and connected to the material roll shaft in a transmission manner. One end of the driving shaft of the driving assembly is detachably connected to one end of the material roll shaft. The driving shaft can drive the material roll shaft to rotate in the opposite direction of the material roll discharge direction, and link the material roll on the material roll shaft to rotate synchronously with the material roll shaft, so that the material stacked between the material roll shaft and the processing equipment is rewound onto the material roll shaft, and the stacked material is tensioned, so that the material fed into the processing equipment remains flat, and the quality problems such as wrinkles and breakages due to unevenness of the material subsequently pressed and formed are avoided. In addition, the driving shaft can also drive the material roll shaft to move axially along the material roll shaft. Through the adaptive engagement between the first speed limiting component and the second speed limiting component of the speed limiting assembly, when the coil shaft rotates in the discharge direction of the material roll, the first speed limiting component and the second speed limiting component rub against each other, and the first speed limiting component applies a damping force on the second speed limiting component that is opposite to the discharge direction of the material roll.

[0021] As described in the background technology, taking the field of paper tableware processing as an example, the production process of paper tableware mainly includes pulping, preliminary paper forming, mold forming and other processes. Among them, the paper is usually thin after preliminary forming and cannot be directly used for mold forming. In order to make the paper tableware have a certain structural strength, it is necessary to perform multi-layer composite pressing of thinner paper to form thicker paper materials, and then process and shape them into the required tableware shape. The specific process of pressing is to pull multiple thin and wound paper materials to the compounding machine for pressing.

[0022] In the prior art, paper stock before composite pressing is wound on a fixed shaft, and the end of the paper stock is pulled to the composite machine by a pulling device. However, since the distance between the fixed shaft and the composite machine is fixed, initially, due to the large diameter of the paper roll, the end of the paper roll is far away from the composite machine. During the process of conveying the paper roll wound on the fixed shaft to the composite machine, the diameter of the paper roll is continuously reduced, and the distance between the end of the paper roll and the composite machine is also gradually reduced, while the paper feeding speed of the composite machine is constant. As the paper roll on the fixed shaft is conveyed, a paper stock stacking problem will occur between the fixed shaft and the composite machine, and the paper stock subsequently pressed and formed may have quality problems such as damage and unevenness.

[0023] Therefore, the prior art has a technical problem that during the outward transmission of the material roll on the fixed shaft, material stacking occurs between the fixed shaft and the processing equipment, which affects the quality of the subsequent processed and formed products.

[0024] In view of the above problems, the utility model provides an adjustable support mechanism for a material roll, which can adjust the tension of the material roll on the material roll shaft, can adjust the axial position of the material roll on the material roll shaft, and can also limit the rotation speed of the material roll shaft along the material roll discharge direction. Of course, the material roll can be the flexible paper material for processing paper tableware mentioned in the background technology, or the flexible cloth in the field of clothing processing, and similar flexible materials in other fields, and no specific restrictions are made here.

[0025] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.

[0026] For ease of understanding, the following implementation is described by taking the process of composite pressing of a flexible paper sheet in a rolled state in the field of paper tableware processing as an example.

[0027] First, the overall structure of the adjustable support mechanism for the material roll is described.

[0028] The utility model provides an adjustable support mechanism for a material roll, such as Figure 1 As shown, it includes a coil shaft 1, a driving component 2 and a speed limiting component 3 arranged at one end of the coil shaft 1 and connected to the coil shaft 1. The driving component 2 can drive the coil shaft 1 to rotate in the opposite direction of the material roll discharge direction, thereby tensioning the materials stacked between the coil shaft 1 and the compound machine, and feeding the materials into the compound machine evenly, so as to avoid the subsequent press-formed materials from wrinkling, breakage and other quality problems due to unevenness. In other words, the axial position adjustment and tensioning force adjustment of the material roll wound on the coil shaft 1 can be achieved through the driving component 2. The speed limiting component 3 can apply a damping force opposite to the discharge direction of the material roll to the coil shaft 1, thereby limiting the rotation speed of the coil shaft 1 in the discharge direction of the material roll, and avoiding the excessive rotation speed of the coil shaft 1 in the discharge direction causing the materials to stack between the coil shaft 1 and the compound machine.

[0029] Specifically, when the outer periphery of the coil shaft 1 is provided with a coil for processing tableware ( Figure 1 ), the winding shaft 1 and the compounding machine ( Figure 1 The material roll (i.e., paper material) is supported by the material roll shaft 1 and is sleeved on the outer periphery of the material roll shaft 1 and can rotate with the material roll shaft 1. The material discharge direction of the material roll shaft 1 is toward the paper inlet of the composite machine, and the material discharge direction is perpendicular to the axial direction of the material roll shaft 1 ( Figure 1 (arrow X direction in the figure).

[0030] It should be noted that the winding shaft 1 can specifically be a rotating shaft with a smooth outer wall surface; it can also be a rotating shaft with a plurality of protrusions on the outer wall surface, and the plurality of protrusions can generate a large friction force with the center of the material roll to avoid relative sliding between the material roll and the winding shaft 1; in one specific embodiment of the present invention, the winding shaft 1 can also be an air-expanding shaft, by inflating the inside of the air-expanding shaft, so that the outer diameter of the shaft is increased and pressed against the material roll to adapt to the material rolls with different axial through-hole diameters, while avoiding relative sliding between the material roll and the winding shaft 1.

[0031] Furthermore, if Figure 1 and Figure 2 As shown, the drive assembly 2 includes a drive shaft 20 ( Figure 2 ), that is, the axial direction of the drive shaft 20 and Figure 1The direction of arrow X in the figure coincides, one end of the drive shaft 20 is detachably connected to one end of the coil shaft 1, and the other end is away from the coil shaft 1. When one end of the drive shaft 20 is in a connected state with one end of the coil shaft 1, the drive shaft 20 can rotate in the opposite direction of the discharge direction of the material roll to drive the coil shaft 1 to rotate synchronously in the opposite direction of the discharge direction of the material roll, and link the material roll on the coil shaft 1 to rotate synchronously with the coil shaft 1, so that the material stacked between the coil shaft 1 and the compound machine is rewound onto the coil shaft 1, and the stacked material is tensioned, so that the material is smoothly fed into the compound machine, avoiding quality problems such as wrinkles and breakages due to unevenness of the subsequent pressed and formed material.

[0032] It should be noted that the connection between the drive shaft 20 and the coil shaft 1 can be specifically connected through mutually adaptable protrusions and recessed parts, or through mutually adaptable external threads and internal threads respectively provided on the drive shaft 20 and the coil shaft 1. As long as it is ensured that when the two are connected, the drive shaft 20 can drive the coil shaft 1 to rotate synchronously in the opposite direction of the discharge direction of the material roll, or drive the coil shaft 1 to move along its axial direction.

[0033] In addition, the driving shaft 20 can also drive the coil shaft 1 to move axially along the coil shaft 1 to accommodate coils with different axial lengths or to adjust according to the distance between the support frames supporting the two ends of the coil shaft 1 .

[0034] It should be noted that the two ends of the drive shaft 20 and the corresponding connections of the winding shaft 1 can be connected to each other by a clamping structure or a screw structure, and the winding shaft 1 can be moved along its axial direction by pushing the drive shaft 20 away from the other end of the winding shaft 1 along the axial direction of the winding shaft 1; the winding shaft 1 can also be moved along its axial direction by setting one end of the drive shaft 20 connected to the winding shaft 1 as a telescopic structure, such as a telescopic rod or a spring, and the telescopic structure can be extended toward the winding shaft 1 to move the winding shaft 1 along its axial direction; a connecting structure can also be set between the drive shaft 20 and the winding shaft 1, one end of the connecting structure is relatively movably connected to the outer periphery of the drive shaft 20, and the other end is fixed to the winding shaft 1, when the connecting structure moves relatively to the outer periphery of the drive shaft 20 along the axial direction of the drive shaft 20 (in the same direction as the axial direction of the winding shaft 1), the winding shaft 1 is driven to move synchronously along its axial direction.

[0035] Furthermore, if Figure 1 and Figure 2As shown, the speed limiting component 3 includes a first speed limiting component 30 and a second speed limiting component 31 adapted to the first speed limiting component 30; wherein the first speed limiting component 30 is rotatably arranged on one side of one end of the winding shaft 1, and the second speed limiting component 31 is fixedly sleeved on the outer periphery of one end of the winding shaft 1, close to the first speed limiting component 30, the first speed limiting component 30 and the second speed limiting component 31 are adapted to engage, when the winding shaft 1 rotates along the discharge direction of the material roll, the second speed limiting component 31 rotates synchronously, and due to the adaptation between the first speed limiting component 30 and the second speed limiting component 31, the first speed limiting component 30 applies a friction damping force opposite to the discharge direction of the material roll to the second speed limiting component 31, and the damping force acts on the second speed limiting component 31 and the winding shaft 1 at the same time, thereby limiting the rotation speed of the winding shaft 1 in conjunction with the second speed limiting component 31 along the discharge direction of the material roll, and avoiding the winding shaft 1 from rotating too fast in the discharge direction, causing the material to stack between the winding shaft 1 and the compound machine.

[0036] It can be understood that the damping force is only used to prevent the winding shaft 1 from rotating too fast along the material roll discharge direction. In fact, the winding shaft 1 is still rotating along the material roll discharge direction.

[0037] It should be noted that the first speed limiting component 30 and the second speed limiting component 31 can specifically be transmission belts that are close to each other and fit together, or they can be gears that are close to each other and mesh with each other. As long as the two are fit together, the first speed limiting component 30 can apply a friction damping force to the second speed limiting component 31 that is opposite to the discharge direction of the material roll.

[0038] In summary, the adjustable support mechanism for the material roll provided in this embodiment can adjust the tension of the material stacked between the roll shaft 1 and the compound machine, so that the material fed into the compound machine remains flat, avoiding quality problems such as wrinkles and breakage of the material subsequently pressed and formed due to unevenness; it can also adjust the distance that the roll shaft 1 moves along its axial direction according to the different axial lengths of the material roll; and avoid the roll shaft 1 rotating too fast in the discharge direction, causing the material to stack between the roll shaft 1 and the compound machine.

[0039] The structure of the driving assembly 2 is described in detail below.

[0040] In one specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the driving assembly 2 also includes a side plate 21, an operating component 22, and a fixed sleeve 23; wherein the side plate 21 is fixedly arranged on a support frame ( Figure 1 and Figure 2The fixing sleeve 23 passes through the side plate 21 and is vertically fixed to the side plate 21, so that the outer periphery of the fixing sleeve 23 is fixed to the side plate 21, and the fixing sleeve 23 is supported by the side plate 21, and as shown in FIG. Figure 2 As shown, the operating member 22 is fixedly arranged at the other end of the drive shaft 20 (i.e., the end away from the winding shaft 1), and is located on the other side of the side plate 21 relative to the winding shaft 1. The operating member 22 assists the rotation or movement of the drive shaft 20, and the side plate 21 can also separate the operating member 22 from the winding shaft 1. In addition, the fixed sleeve 23 can be relatively rotatably sleeved on the outer periphery of the portion where the drive shaft 20 and the winding shaft 1 are connected to each other. The fixed sleeve 23 is coaxially arranged with the drive shaft 20 and the winding shaft 1, that is, the axial direction of the fixed sleeve 23 is the same as that of the winding shaft 1. Figure 1 The direction of the arrow X in the figure coincides, so that the drive shaft 20 and the winding shaft 1 are supported on the side plate 21 by the fixed sleeve 23, and can rotate relative to the fixed sleeve 23 to achieve the tension adjustment of the material roll or the axial adjustment of the winding shaft 1, etc.

[0041] It should be noted that the operating component 22 can be a rotating handle, a turntable or other structure that can assist the rotation of the driving shaft 20, which is fixedly connected to the end of the driving shaft 20 away from the coil shaft 1, as long as it is arranged at the other end of the driving shaft 20 to facilitate the application of driving force to the driving shaft 20. In one achievable embodiment of the utility model, the operating component 22 is preferably a rotating handle, which is connected to the other end of the driving shaft 20 by rotating the handle, and the rotation of the driving shaft 20 can be achieved by applying a small force.

[0042] Furthermore, if Figure 2 As shown, in one specific embodiment of the utility model, a guide member 24 is further provided in the fixed sleeve 23. In the axial direction of the fixed sleeve 23, the guide member 24 is located on the side of one end of the winding shaft 1 close to the driving shaft 20, and one end of the driving shaft 20 is relatively movably arranged in the guide hole 241 at the center of the guide member 24 along the axial direction of the fixed sleeve 23. Since the end of the driving shaft 20 close to the winding shaft 1 is detachably connected to the end corresponding to the winding shaft 1, the connection stability between the two is poor, especially when the end of the driving shaft 20 close to the winding shaft 1 is separated from the winding shaft 1, by passing the end through the guide hole 241 of the guide member 24, the guide member 24 provides support force to the driving shaft 20, and the guide hole 241 plays a certain limiting and guiding role on the end.

[0043] It should be noted that relatively movable means: when the inner wall of the guide hole 241 and the outer periphery of the drive shaft 20 are in a sliding connection structure, the guide member 24 is fixed to the fixed sleeve 23, and when the drive shaft 20 moves along the axial direction of the fixed sleeve 23, one end of the drive shaft 20 arranged in the guide hole 241 at the center of the guide member 24 moves relative to the guide member 24; or when the inner wall of the guide hole 241 and the outer periphery of the drive shaft 20 are in a rotating connection structure, when the drive shaft 20 rotates along its axial direction, the guide member 24 moves relatively along the axial direction of the drive shaft 20, and slides relatively to the fixed sleeve 23.

[0044] Furthermore, if Figure 2 As shown, a coupling portion 201 is provided at one end of the driving shaft 20, and a coupled portion 10 is provided at one end of the winding shaft 1. The coupling portion 201 and the coupled portion 10 are adapted to be non-rotatable with each other. When the coupling portion 201 and the coupled portion 10 are adapted to be engaged with each other, the corresponding ends of the driving shaft 20 and the winding shaft 1 are locked with each other. When the driving shaft 20 rotates, the winding shaft 1 rotates synchronously; when the driving shaft 20 moves along its axial direction, the winding shaft 1 is linked to move synchronously.

[0045] Specifically, in one specific embodiment of the present invention, the coupling portion 201 provided at one end of the driving shaft 20 is a plurality of protrusions evenly distributed around one end of the driving shaft 20, and the coupled portion 10 provided at one end of the winding shaft 1 is a plurality of recessed portions opened at the center of the shaft end of one end of the winding shaft 1, and each recessed portion is adapted in shape to a corresponding protrusion. When the plurality of protrusions are respectively connected to each recessed portion, the corresponding ends of the driving shaft 20 and the winding shaft 1 are locked with each other through this "recessed and protruding" shape adaptation structure, so that the two can rotate or move synchronously.

[0046] Or, if Figure 2 As shown, the engaging portion 201 provided at one end of the driving shaft 20 is an external thread provided around one end of the driving shaft 20, and the engaged portion 10 provided at one end of the winding shaft 1 is an internal thread provided at the inner periphery of the recessed portion opened at the center portion of the shaft end of one end of the winding shaft 1, and the external thread and the internal thread are adapted to each other, and when the external thread and the internal thread are threadedly connected, the corresponding ends of the driving shaft 20 and the winding shaft 1 are locked with each other, so that the two can rotate or move synchronously.

[0047] In one specific embodiment of the present invention, Figure 2As shown, an intermediate sleeve 25 is further provided between one end of the winding shaft 1 and the fixed sleeve 23, and one end of the winding shaft 1 extends into the intermediate sleeve 25 and is rotatably supported in the intermediate sleeve 25 by at least one pair of bearings 26; one end of the intermediate sleeve 25 close to the drive shaft 20 is fixedly connected to the guide 24; the outer peripheral wall of the intermediate sleeve 25 is rotatably abutted against the inner peripheral wall of the fixed sleeve 23, and when the drive shaft 20 and the winding shaft 1 are in a separated state, the end of the intermediate sleeve 25 close to the drive shaft 20 can move relative to the drive shaft 20 along the axial direction of the fixed sleeve 23 through the guide 24. , the other end is rotatably connected to the winding shaft 1 through a bearing 26, but the bearing 26 is fixed between the intermediate sleeve 25 and the winding shaft 1 along the axial direction of the fixed sleeve 23. When the guide member 24 moves axially along the fixed sleeve 23 relative to the driving shaft 20, the intermediate sleeve 25 moves synchronously. Since one end of the winding shaft 1 is supported in the intermediate sleeve 25 by the bearing 26, the intermediate sleeve 25 can also drive one end of the winding shaft 1 to move axially along the fixed sleeve 23, so that the axial position of the winding shaft 1 can be adjusted, and specifically, it can be adjusted according to the different axial lengths of the material roll.

[0048] It should be noted that the bearings 26 can be provided with two (i.e., one pair), three, four, etc., and those skilled in the art can select the specific number according to actual needs, as long as at least one pair is spaced and correspondingly arranged at both ends of the intermediate sleeve 25 to provide support for the coil shaft 1, and when the number of bearings 26 is greater than or equal to two, multiple bearings 26 can be evenly spaced along the axial direction of the intermediate sleeve 25, and the specific number and position are not specifically limited here. The bearings 26 can specifically be sliding bearings, ball bearings, bearing bushes, etc., as long as they can support the coil shaft 1 in the intermediate sleeve 25 and allow the coil shaft 1 and the intermediate sleeve 25 to rotate relative to each other.

[0049] Furthermore, a limiting threaded hole 231 is provided on the side wall in the overlapping area of ​​the fixed sleeve 23 and the intermediate sleeve 25, and a limiting groove 251 extending along the axial direction of the fixed sleeve 23 is provided at a position of the intermediate sleeve 25 corresponding to the limiting threaded hole 231. An adjustable limiting bolt 27 is threadedly engaged in the limiting threaded hole 231, and the end thereof is detachably abutted against the bottom wall of the limiting groove 251. When the intermediate sleeve 25 is moved to a suitable position along the axial direction of the fixed sleeve 23, the adjustable limiting bolt 27 is tightened so that it abuts against the limiting groove 251, thereby fixing the intermediate sleeve 25, and indirectly fixing the position of the winding shaft 1 along the axial direction of the fixed sleeve 23.

[0050] The specific structure of the speed limiting component 3 is described below.

[0051] In one specific embodiment of the present invention, Figure 1 and Figure 2As shown, the first speed limiting component 30 includes a damper 301 and a first gear 302 which are coaxially arranged, and the second speed limiting component 31 includes a second gear 311 which is fixedly sleeved on the outer periphery of the one end of the winding shaft 1, and the first gear 302 and the second gear 311 are meshed with each other. When the winding shaft 1 rotates along the discharge direction of the material roll, the second gear 311 rotates synchronously, and the damper 301 transmits torque to the first gear 302, so that the first gear 302 applies a reverse force to the second gear 311 at the meshing point between the first gear 302 and the second gear 311, that is, the first gear 302 applies a friction damping force to the second gear 311 which is opposite to the discharge direction of the material roll, and the damping force acts on the second gear 311 and the winding shaft 1 at the same time, thereby limiting the rotation speed of the winding shaft 1 in the discharge direction of the material roll in conjunction with the second gear 311, so as to avoid the winding shaft 1 rotating too fast in the discharge direction and causing the material to stack between the winding shaft 1 and the compound machine.

[0052] Furthermore, if Figure 1 and Figure 3 As shown, in one specific embodiment of the utility model, the first speed limiting component 30 also includes a component bracket 303, which is fixedly arranged on the side plate 21, on the same side as the winding shaft 1 and close to the winding shaft 1; and the component bracket 303 includes a bracket plate 3031 spaced apart and parallel to the side plate 21, the first gear 302 is located on the side of the bracket plate 3031 away from the side plate 21, the damper 301 is located between the bracket plate 3031 and the side plate 21, and the first gear 302 and the damper 301 are coaxially connected through an axis passing through the bracket plate 3031, the first gear 302 and the damper 301 are respectively arranged at both ends of the bracket plate 3031, and the two are separated by the bracket plate 3031 to avoid interference between the gear and the bracket plate 3031 when the gear rotates.

[0053] It should be noted that the damper 301 can specifically be an element that uses the principle of electromagnetic induction to generate damping force, such as a magnetic powder brake. When the damper 301 is specifically a magnetic powder brake, the rotating shaft of the magnetic powder brake is coaxially connected to the center hole of the first gear 302, so that the magnetic powder brake can output torque to the first gear 302, so that the first gear 302 and the second gear 311 are connected by transmission, and a damping force opposite to the discharge direction of the material roll is applied to the second gear 311, thereby limiting the rotation speed of the coil shaft 1 and the second gear 311 along the discharge direction of the material roll, and avoiding the coil shaft 1 from rotating too fast in the discharge direction, causing the material to stack between the coil shaft 1 and the compound machine.

[0054] In one specific embodiment of the present invention, Figure 1 and Figure 3As shown, the adjustable material roll support mechanism also includes a limit unit 4, which includes a limit rod 40 extending from the side plate 21, on the same side as the winding shaft 1 and close to the winding shaft 1, along the axial direction parallel to the winding shaft 1, and a limit plate 41 arranged at the end of the limit rod 40; wherein in the axial direction of the winding shaft 1, the limit plate 41 is closer to the material roll than the second gear 311. Since the material roll on the winding shaft 1 rotates continuously with the winding shaft 1 and can also be adjusted along the axial direction of the winding shaft 1, in order to avoid the axial end face of the material roll from interfering with the second gear 311, the axial end face of the material roll is blocked and limited by the limit plate 41.

[0055] In order to facilitate those skilled in the art to clearly understand the use process of the adjustable material roll support mechanism provided by the specific embodiment of the utility model, the use process of the adjustable material roll support mechanism is described below:

[0056] When the material roll is discharged normally in the discharge direction, the material roll is sleeved on the coil shaft 1, and the coil shaft 1 rotates in the discharge direction. When the coil shaft 1 is an air-expanding shaft, before the material roll is sleeved, the air-expanding shaft is not inflated, and the diameter of the air-expanding shaft is small, which is convenient for sleeved the material roll. After the material roll is sleeved, the air-expanding shaft is inflated to increase the diameter of the air-expanding shaft and squeeze the material roll tightly to avoid the material roll slipping.

[0057] During the rotation of the coil shaft 1 along the discharge direction, the first speed limiting component 30 is adapted to engage with the second speed limiting component 31, and the first speed limiting component 30 applies a friction damping force opposite to the discharge direction of the material roll to the second speed limiting component 31, and the damping force acts on the second speed limiting component 31 and the coil shaft 1 at the same time, thereby limiting the rotation speed of the coil shaft 1 and the second speed limiting component 31 along the discharge direction of the material roll, thereby preventing the coil shaft 1 from rotating too fast in the discharge direction and causing the material to stack between the coil shaft 1 and the compound machine. When the first speed limiting component 30 includes a damper 301 and a first gear 302, and the second speed limiting component 31 includes a second gear 311, the first gear 302 and the second gear 311 are meshed with each other, and the second gear 311 rotates in the discharge direction of the material roll. The damper 301 transmits torque to the first gear 302, so that the first gear 302 applies a reverse force to the second gear 311 at the meshing point between the first gear 302 and the second gear 311, that is, the first gear 302 applies a damping force opposite to the discharge direction of the material roll to the second gear 311, and the damping force acts on the second gear 311 and the winding shaft 1 at the same time, thereby limiting the rotation speed of the winding shaft 1 in conjunction with the second gear 311 in the discharge direction of the material roll, thereby preventing the winding shaft 1 from rotating too fast in the discharge direction, causing the material to stack between the winding shaft 1 and the compound machine.

[0058] As the material roll is continuously conveyed in the discharge direction, the diameter of the material roll on the coil shaft 1 becomes smaller and smaller, and the distance between the end of the material roll and the laminating machine (or other equipment for processing the material) also gradually decreases, while the feeding speed of the laminating machine is constant. As the material roll on the coil shaft 1 is conveyed, a paper stacking problem will occur between the coil shaft 1 and the laminating machine. The drive shaft 20 is connected to the coil shaft 1, and the drive shaft 20 is rotated in the opposite direction of the discharge direction of the material roll to drive the coil shaft 1 to rotate synchronously in the opposite direction of the discharge direction of the material roll, and the material roll on the coil shaft 1 is linked to rotate synchronously with the coil shaft 1, so that the stacked material between the coil shaft 1 and the laminating machine is rewound onto the coil shaft 1, and the stacked material is tensioned, so that the material fed into the laminating machine remains flat, and the subsequent pressed and formed material is prevented from having quality problems such as wrinkles and breakage due to unevenness.
