Description

Technical Field

[0001] This application relates to the field of material conveying technology, and more specifically, to a feeding device. Background Technology

[0002] Some materials are wound onto a core cylinder to form a roll, which is then processed. The roll needs to be fed to subsequent processes via a feeding device. The axial length relationship between the core cylinder and the rolled material varies for different rolls, making it inconvenient for the feeding device to load the rolls. Utility Model Content

[0003] In view of this, this application provides a feeding device capable of loading different rolls of material.

[0004] One embodiment of this application provides a feeding device. The feeding device includes at least one of a first feeding assembly and a second feeding assembly. The first feeding assembly includes a first clamping member. Two first clamping members are provided and disposed opposite to each other. The two first clamping members are configured to approach each other to clamp a material roll. The second feeding assembly includes a second clamping member and a feeding shaft. Two second clamping members are provided and disposed opposite to each other. The two second clamping members are configured to approach each other to clamp the feeding shaft. The feeding shaft is configured to pass through the material roll.

[0005] In the above embodiments, for rolls of material where the core tube is longer than the rolled material along its axial length, the material can be loaded into the first feeding assembly. Two first clamping members clamp the core tube of the roll close to each other, thus loading the roll and allowing the rolled material to be unwound normally. For rolls of material where the core tube is shorter than or equal to the rolled material along its axial length, the material can be loaded into the second feeding assembly. A feeding shaft passes through the core tube, thus fixing the roll relatively to the feeding shaft. Two second clamping members clamp the feeding shaft close to each other, thus loading the roll and allowing the rolled material to be unwound normally. Therefore, by providing the first and second feeding assemblies, the feeding device can load correspondingly suitable rolls.

[0006] In some embodiments of this application, each first clamping member is configured to engage with the core of the coil. Each first clamping member is configured to have a first protrusion or a first recess. When the first clamping member has a first protrusion, the first protrusion is configured to be inserted into the core. When the first clamping member has a first recess, the first recess is configured for inserting the core.

[0007] In the above embodiments, the first clamping member achieves insertion and engagement with the core cylinder through the first protrusion or the first recess, which can fix the material roll along the axial direction of the roll, so that the roll material can be unwound normally, and realize the loading of the material roll by the first feeding component.

[0008] In some embodiments of this application, the first clamping member has a first guiding surface. When the first clamping member has a first protrusion, the first guiding surface is located at the first protrusion; and along the direction in which the core cylinder is inserted into the first protrusion, the first guiding surface gradually moves away from the axis of the material roll. When the first clamping member has a first recess, the first guiding surface is located at the first recess; and along the direction in which the core cylinder is inserted into the first recess, the first guiding surface gradually moves closer to the axis of the material roll.

[0009] In the above embodiments, the first protrusion and the first recess, by providing a first guide surface, can guide the position of the material roll during the insertion process of the first clamping member and the material roll, thereby reducing the difficulty of insertion and mating.

[0010] In some embodiments of this application, one of the second clamping member and the feeding shaft has a second protrusion, and the other has a second recess. The second protrusion is inserted into the second recess.

[0011] In the above embodiments, the second clamping member and the feeding shaft are connected by the insertion of the second protrusion and the second recess, which can fix the feeding shaft along the axial direction of the feeding shaft, so that the rolled material can be unwound normally, and the second feeding assembly can load the material roll.

[0012] In some embodiments of this application, the second protrusion has a second guide surface and / or the second recess has a third guide surface. Along the direction in which the second protrusion is inserted into the second recess, the second guide surface gradually moves away from the axis of the feed shaft, and the third guide surface gradually moves closer to the axis of the feed shaft.

[0013] In the above embodiments, by providing a second guide surface and / or a third guide surface, the position of the feed shaft can be guided during the insertion process of the second clamping member and the feed shaft, thereby reducing the difficulty of insertion and mating.

[0014] In some embodiments of this application, the feed shaft includes a shaft body and a positioning portion. Two second clamping members are configured to approach each other to clamp the shaft body. The shaft body is configured to pass through a material roll. The positioning portion is provided on the shaft body. The positioning portion is configured to protrude from the surface of the shaft body along the axis of the shaft body and to change the height of the protrusion from the surface of the shaft body.

[0015] In the above embodiments, by making the positioning part protrude from the surface of the shaft body and increasing the height of the protrusion, the positioning part can support the material roll relative to the shaft body when the shaft body is inserted into the material roll, thereby fixing the material roll to the shaft body. By reducing the height of the positioning part protruding from the surface of the shaft body, it is easier for the shaft body to be inserted into the material roll, thereby facilitating the replacement of the material roll.

[0016] In some embodiments of this application, the feed shaft is configured to change the height of the positioning portion protruding from the surface of the shaft body by inflating and / or deflating.

[0017] In the above embodiments, the height of the positioning part protruding from the surface of the shaft body is adjusted by inflation and deflation. The control method is simple and, compared with electric or hydraulic drive control methods, it is beneficial to simplify the structural design of the feeding shaft. The inflation and deflation structure does not require much space.

[0018] In some embodiments of this application, the feeding device further includes an adapter frame and an adapter seat. Two adapter frames are provided and arranged opposite to each other. A first feeding assembly and / or a second feeding assembly are provided on the adapter frame. Each adapter frame has at least one adapter seat. Each adapter seat is connected to a first clamping member or a second clamping member. The adapter seat of at least one adapter frame is configured to be movable relative to the adapter frame along the distribution direction of the two adapter frames.

[0019] In the above embodiments, the adapter seat moves relative to the adapter frame, thereby driving the connected first or second clamping member to move, so that the two first clamping members or the two second clamping members move closer to each other, thereby loading the material. By controlling the movement of the adapter seat, the movement of the first or second clamping member can be controlled. Therefore, by replacing the first or second clamping member connected to the adapter seat, the first and second feeding components can be replaced, thereby enabling the loading of different material rolls as needed.

[0020] In some embodiments of this application, both the first feeding assembly and the second feeding assembly are disposed on a transfer frame. Each transfer frame is connected to at least one first clamping member and at least one second clamping member. The feeding device further includes a rotary drive assembly. The rotary drive assembly connects the two transfer frames. The rotary drive assembly is configured to drive the two transfer frames to rotate. The rotation axis of the transfer frame is parallel to the axis of the feeding shaft.

[0021] In the above embodiments, the adapter frame is equipped with both a first feeding component and a second feeding component, enabling the feeding device to load different rolls simultaneously and expanding its applicability. Furthermore, a rotary drive component is provided to drive the adapter frame to rotate, thereby adjusting the positions of the first and second feeding components to allow for selection of whether to unload the roll loaded by the first or second feeding component as needed.

[0022] In some embodiments of this application, the feeding device further includes a telescopic drive assembly. At least one adapter frame is provided with the telescopic drive assembly. The telescopic drive assembly is connected to the adapter seat. The telescopic drive assembly is configured to drive the adapter seat to move along the distribution direction of the two adapter frames, so that the two first clamping members move closer to each other and / or the two second clamping members move closer to each other.

[0023] In the above embodiments, by setting a telescopic drive assembly, the adapter seat is moved relative to the adapter frame, thereby realizing the clamping of the material roll by the two first clamping members or the clamping of the feed shaft by the two second clamping members.

[0024] In some embodiments of this application, the feeding device further includes a telescopic tube assembly. Each adapter is connected to the adapter frame via a telescopic tube assembly. The telescopic tube assembly includes a sleeve and an inner core. The sleeve is disposed on the adapter. A telescopic drive assembly is configured to drive the sleeve to move. The sleeve is fitted onto the inner core. The inner core is configured to rotate relative to the sleeve. The inner core is connected to the adapter.

[0025] In the above embodiments, the telescopic drive assembly drives the sleeve to move, which in turn drives the inner core to move, thereby moving the adapter seat. The inner core can rotate relative to the sleeve, causing the adapter seat to rotate relative to the sleeve. Therefore, the adapter seat can move relative to the adapter frame to allow the first clamping member to clamp the material or the second clamping member to clamp the feed shaft. The adapter seat can also rotate relative to the adapter frame to allow the first or second feeding assembly to rotate, thereby achieving the unwinding of the rolled material.

Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0035] The term “and / or” as used herein includes any and all combinations of one or more of the related listed items.

[0036] Furthermore, the terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0037] Embodiments of this application provide a feeding device. The feeding device includes at least one of a first feeding assembly and a second feeding assembly. The first feeding assembly includes a first clamping member. Two first clamping members are provided and disposed opposite to each other. The two first clamping members are configured to approach each other to clamp a material roll. The second feeding assembly includes a second clamping member and a feeding shaft. Two second clamping members are provided and disposed opposite to each other. The two second clamping members are configured to approach each other to clamp the feeding shaft. The feeding shaft is configured to pass through the material roll.

[0038] For rolls where the core tube is longer than the rolled material along its axial length, the material can be loaded into the first feeding assembly. Two first clamping members clamp the core tube of the roll close to each other, thus loading the roll and allowing the rolled material to be unwound normally. For rolls where the core tube is shorter than or equal to the rolled material along its axial length, the material can be loaded into the second feeding assembly. In this assembly, a feeding shaft passes through the core tube, thus fixing the roll relatively to the feeding shaft. Two second clamping members clamp the feeding shaft close to each other, thus loading the roll and allowing the rolled material to be unwound normally. Therefore, by providing the first and second feeding assemblies, the feeding device can load correspondingly suitable rolls.

[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] See Figure 1 , Figure 2 and Figure 4 One embodiment of this application provides a feeding device 100. The feeding device 100 is used to load a material roll 200 and feed it to subsequent processes.

[0041] See Figures 2 to 4 In some embodiments, the roll 200 includes a core 201 and a material 202. The material 202 is wound around the core 201.

[0042] Understandably, in some embodiments, material 202 is a porous and fibrous material, including one or more of glass fibers, carbon fibers, or chemical fibers. For example, material 202 can be glass fiber cloth; the feeding device 100 feeds the glass fiber cloth to the dust removal operation mechanism after loading the roll 200.

[0043] In some embodiments, the lengths of the rolled material 202 and the core tube 201 along the axial direction of the roll 200 are different. For example, along the axial direction of the roll 200, the end of the core tube 201 protrudes beyond the end of the rolled material 202 (see [link]). Figure 2 ), or the end of the core 201 is flush with the end of the rolled material 202 (see Figure 3 Alternatively, the end of the core tube 201 may be tucked inside the end of the rolled material 202 (not shown).

[0044] In other embodiments, the core tube 201 may be omitted, and the material roll 200 is simply a roll of material 202.

[0045] See Figure 1 , Figure 2 and Figure 4In some embodiments, the feeding device 100 includes at least one of a first feeding assembly 10 and a second feeding assembly 20. The first feeding assembly 10 includes two first clamping members 11 arranged opposite each other. The two first clamping members 11 are configured to approach each other to clamp the material roll 200. The second feeding assembly 20 includes two second clamping members 21 and a feeding shaft 22. The two second clamping members 21 are arranged opposite each other. The two second clamping members 21 are configured to approach each other to clamp the feeding shaft 22. The feeding shaft 22 is configured to pass through the material roll 200.

[0046] For a roll 200 whose axial length is longer than that of the rolled material 202, the core cylinder 201 can be loaded into the first feeding assembly 10. Two first clamping members 11 clamp the core cylinder 201 of the roll 200 close to each other, thus loading the roll 200 and allowing the rolled material 202 to unwind normally. For a roll 200 whose axial length is shorter than or equal to that of the rolled material 202, the core cylinder 201 can be loaded into the second feeding assembly 20. A feeding shaft 22 passes through the core cylinder 201, thus fixing the roll 200 relative to the feeding shaft 22. Two second clamping members 21 clamp the feeding shaft 22 close to each other, thus loading the roll 200 and allowing the rolled material 202 to unwind normally. Therefore, by providing the first feeding assembly 10 and the second feeding assembly 20, the feeding device 100 can load correspondingly adapted rolls 200.

[0047] Understandably, in some embodiments, regardless of the length relationship between the rolled material 202 and the core cylinder 201 along the axial direction of the roll 200, or whether the roll 200 includes the core cylinder 201, various rolls 200 can be loaded onto the second feeding assembly 20. However, when the roll 200 is loaded onto the second feeding assembly 20, the feeding shaft 22 needs to pass through the roll 200, and then be clamped by the second clamping member 21; compared with the first clamping member 11 directly clamping the roll 200, loading the roll 200 onto the first feeding assembly 10 is more convenient. However, some rolls 200 are not convenient to be directly loaded onto the first feeding assembly 10. For example, rolls 200 without a core cylinder 201, or rolls 200 whose length of the rolled material 202 along the axial direction of the roll 200 is greater than or equal to the length of the core cylinder 201, may not be able to be unwound smoothly due to the clamping force of the first clamping member 11. Therefore, the feeding device 100 improves the efficiency of loading material 202 by setting the first feeding component 10, and loads material rolls 200 that are inconvenient to be loaded into the first feeding component 10 by setting the second feeding component 20.

[0048] See Figure 2 and Figure 3In some embodiments, each first clamping member 11 is configured to insert into the core cylinder 201 of the material roll 200. Each first clamping member 11 is configured to have a first protrusion 111 or a first recess 113. When the first clamping member 11 has the first protrusion 111, the first protrusion 111 is configured to be inserted into the core cylinder 201. When the first clamping member 11 has the first recess 113, the first recess 113 is configured for the core cylinder 201 to be inserted. The insertion direction of the first clamping member 11 and the core cylinder 201 is such that the two first clamping members 11 are close to each other and clamp the material roll 200.

[0049] The first clamping member 11, through the first protrusion 111 or the first recess 113, achieves insertion and engagement with the core cylinder 201, and can fix the material roll 200 along the axial direction of the material roll 200, so that the roll material 202 can be unwound normally, and realize the loading of the material roll 200 by the first feeding component 10.

[0050] It is understood that, in some embodiments, depending on the shape of the end of the core tube 201, the first feeding assembly 10 may be selected between a first clamping member 11 having a first protrusion 111 or a first clamping member 11 having a first recess 113.

[0051] In some embodiments, the first clamping member 11 has a first guiding surface 112. See also Figure 2 When the first clamping member 11 has a first protrusion 111, the first guide surface 112 is located at the first protrusion 111; and along the direction in which the core cylinder 201 is inserted into the first protrusion 111, the first guide surface 112 gradually moves away from the axis of the material roll 200. See also Figure 3 When the first clamping member 11 is provided with the first recess 113, the first guide surface 112 is located in the first recess 113; and along the direction in which the core cylinder 201 is inserted into the first recess 113, the first guide surface 112 gradually approaches the axis of the material roll 200.

[0052] The first protrusion 111 and the first recess 113, by providing the first guide surface 112, can guide the position of the material roll 200 during the insertion process of the first clamping member 11 and the material roll 200, thereby reducing the difficulty of insertion and engagement.

[0053] It is understood that in some embodiments, the first guide surface is an inclined surface and distributed in a ring at intervals or in a ring continuously, or the first guide surface is conical or frustum-shaped.

[0054] See Figure 4In some embodiments, one of the second clamping member 21 and the feeding shaft 22 is provided with a second protrusion 2211, and the other is provided with a second recess 211. The second protrusion 2211 is inserted into the second recess 211. The insertion and engagement direction of the second clamping member 21 and the feeding shaft 22 is such that the two second clamping members 21 are close to each other and clamp the feeding shaft 22.

[0055] By inserting the second protrusion 2211 and the second recess 211, the second clamping member 21 and the feeding shaft 22 are connected and engaged, which can fix the feeding shaft 22 along the axial direction of the feeding shaft 22, so that the rolled material 202 can be unwound normally, and the second feeding assembly 20 can load the material roll 200.

[0056] In some embodiments, the second protrusion 2211 has a second guide surface 2212 and / or the second recess 211 has a third guide surface 212. Along the direction in which the second protrusion 2211 inserts into the second recess 211, the second guide surface 2212 gradually moves away from the axis of the feed shaft 22, and the third guide surface 212 gradually moves closer to the axis of the feed shaft 22. When the second feeding assembly 20 loads the material roll 200, the axis of the feed shaft 22 and the axis of the material roll 200 coincide.

[0057] By setting the second guide surface 2212 and / or the third guide surface 212, the position of the feed shaft 22 can be guided during the insertion of the second clamping member 21 and the feed shaft 22, thereby reducing the difficulty of insertion and mating.

[0058] It is understood that in some embodiments, the second guide surface is an inclined surface with annular intervals or annular continuous distribution, or the second guide surface is conical or frustum-shaped. The third guide surface is an inclined surface with annular intervals or annular continuous distribution, or the third guide surface is conical or frustum-shaped.

[0059] In some embodiments, the feed shaft 22 includes a shaft body 221 and a positioning portion 222. Two second clamping members 21 are configured to approach each other to clamp the shaft body 221. The shaft body 221 is configured to pass through the material roll 200. The positioning portion 222 is provided on the shaft body 221. The positioning portion 222 is configured to protrude from the surface of the shaft body 221 along the axis of the shaft body 221 and to change the height of the protrusion from the surface of the shaft body 221.

[0060] By making the positioning part 222 protrude from the surface of the shaft body 221 and increasing the height of the protrusion, the positioning part 222 can support the material roll 200 relative to the shaft body 221 when the shaft body 221 is inserted into the material roll 200, thereby fixing the material roll 200 to the shaft body 221. By reducing the height of the positioning part 222 protruding from the surface of the shaft body 221, it is easier for the shaft body 221 to be inserted into the material roll 200, thereby facilitating the replacement of the material roll 200.

[0061] It is understood that the shaft body 221 is provided with a second protrusion 2211 or a second recess 211.

[0062] In some embodiments, the feed shaft 22 is configured to change the height of the positioning portion 222 protruding from the surface of the shaft body 221 by inflating and / or deflating.

[0063] The height of the positioning part 222 protruding from the surface of the shaft body 221 is adjusted by inflation and deflation. The control method is simple and, compared with electric or hydraulic drive control methods, it is beneficial to simplify the structural design of the feeding shaft 22. The inflation and deflation structure does not require much space.

[0064] In some embodiments, the shaft body 221 has an air bladder or air cavity inside, and the positioning part 222 is a structural member that can move relative to the shaft body 221. By inflating the shaft body 221, the positioning part 222 can be lifted up, thereby increasing the height of the positioning part 222 protruding from the surface of the shaft body 221. By deflating the shaft body 221, the positioning part 222 can be lowered down, thereby reducing the height of the positioning part 222 protruding from the surface of the shaft body 221.

[0065] In other embodiments, the positioning part 222 is an airbag. By inflating and / or deflating the positioning part 222, the height of the positioning part 222 protruding from the surface of the shaft body 221 can be changed.

[0066] In other embodiments, the feed shaft 22 further includes an elastic element. The positioning part 222 is connected to the shaft body 221 via the elastic element. The elastic element, through elastic deformation, causes the positioning part 222 to move relative to the shaft body 221, thereby changing the height of the positioning part 222 protruding from the surface of the shaft body 221. For example, the elastic element may be a helical spring.

[0067] See Figure 1 , Figure 2 and Figure 4 In some embodiments, the feeding device 100 further includes an adapter frame 30 and an adapter seat 40. Two adapter frames 30 are provided and arranged opposite each other. A first feeding assembly 10 and / or a second feeding assembly 20 are disposed on the adapter frame 30. Each adapter frame 30 has at least one adapter seat 40. Each adapter seat 40 is connected to a first clamping member 11 or a second clamping member 21. The adapter seat 40 of at least one adapter frame 30 is configured to be movable relative to the adapter frame 30 along the distribution direction of the two adapter frames 30.

[0068] The adapter 40 moves relative to the adapter frame 30, thereby moving the connected first clamping member 11 or second clamping member 21, so that the two first clamping members 11 or the two second clamping members 21 move closer to each other, thereby loading the material. The movement of the first clamping member 11 or the second clamping member 21 can be controlled by controlling the movement of the adapter 40. Therefore, by changing the first clamping member 11 or the second clamping member 21 connected to the adapter 40, the first feeding assembly 10 and the second feeding assembly 20 can be replaced, thereby enabling the loading of different material rolls 200 as needed.

[0069] In some embodiments, both the first feeding assembly 10 and the second feeding assembly 20 are disposed on the adapter 30. Each adapter 30 is connected to at least one first clamping member 11 and at least one second clamping member 21. The feeding device 100 further includes a rotary drive assembly 50. The rotary drive assembly 50 connects the two adapters 30. The rotary drive assembly 50 is configured to drive the two adapters 30 to rotate. The rotation axis of the adapter 30 is parallel to the axis of the feeding shaft 22.

[0070] The adapter frame 30 is equipped with both a first feeding assembly 10 and a second feeding assembly 20, enabling the feeding device 100 to simultaneously load different rolls 200, thus expanding its applicability. Furthermore, a rotary drive assembly 50 drives the adapter frame 30 to rotate, thereby adjusting the positions of the first feeding assembly 10 and the second feeding assembly 20. This allows for the selection of whether to unload the roll 200 loaded by the first feeding assembly 10 or the roll 200 loaded by the second feeding assembly 20, as needed.

[0071] In some embodiments, each adapter frame 30 includes four adapter arms 31. One end of the four adapter arms is connected to each other, and adjacent adapter arms are arranged at 90° to each other. Two adapter arms arranged at 180° are respectively connected to a first feeding assembly 10, and the other two adapter arms arranged at 180° are respectively connected to a second feeding assembly 20.

[0072] See Figures 2 to 4 In some embodiments, the feeding device 100 further includes a telescopic drive assembly 60. At least one adapter 30 is provided with the telescopic drive assembly 60. The telescopic drive assembly 60 is connected to the adapter 40. The telescopic drive assembly 60 is configured to drive the adapter 40 to move along the distribution direction of the two adapters 30, so that the two first clamps 11 move closer to each other and / or the two second clamps 21 move closer to each other.

[0073] By setting the telescopic drive assembly 60, the adapter seat 40 is moved relative to the adapter frame 30, thereby realizing the clamping of the material roll 200 by the two first clamping members 11 or the clamping of the feed shaft 22 by the two second clamping members 21.

[0074] In some embodiments, the feeding device 100 further includes a telescopic tube assembly 70. Each adapter seat 40 is connected to the adapter frame 30 via a telescopic tube assembly 70. The telescopic tube assembly 70 includes a sleeve 71 and an inner core 72. The sleeve 71 is disposed on the adapter seat 40. The telescopic drive assembly 60 is configured to drive the sleeve 71 to move. The sleeve 71 is fitted onto the inner core 72. The inner core 72 is configured to rotate relative to the sleeve 71. The inner core 72 is fixed relative to the sleeve 71 in the direction of its own rotation axis. The inner core 72 is connected to the adapter seat 40. The inner core 72 may be solid and cylindrical; or it may be hollow and tubular.

[0075] The telescopic drive assembly 60 drives the sleeve 71 to move, which in turn drives the inner core 72 to move, thereby driving the adapter 40 to move. The inner core 72 can rotate relative to the sleeve 71, thus causing the adapter 40 to rotate relative to the sleeve 71. Therefore, the adapter 40 can move relative to the adapter frame 30 to allow the first clamping member 11 to clamp the material 202 or the second clamping member 21 to clamp the feed shaft 22. The adapter 40 can also rotate relative to the adapter frame 30 to allow the first feeding assembly 10 or the second feeding assembly 20 to rotate, thereby realizing the unwinding of the rolled material 202.

[0076] See Figure 1 In some embodiments, the feeding device 100 further includes a frame 80. An adapter 30 is rotatably connected to the frame 80. A rotation drive assembly 50 is disposed on the frame 80 to drive the adapter 30 to rotate relative to the frame 80.

[0077] See Figure 1 , Figure 2 and Figure 4 In some embodiments, the feeding device 100 operates as follows:

[0078] When the material roll 200 can be loaded into the first feeding assembly 10, the two first clamping members 11 move closer to each other, so that the first clamping members 11 and the material roll 200 are inserted into each other and clamp the material roll 200; the adapter frame 30 rotates from the posture of receiving the material roll 200 to the posture of feeding the material roll 200 into the first feeding assembly 10. When the material roll 200 can be loaded into the second feeding assembly 20, the feeding shaft 22 passes through the material roll 200, the two second clamping members 21 move closer to each other, so that the second clamping members 21 and the feeding shaft 22 are inserted into each other and clamp the feeding shaft 22; the adapter frame 30 rotates from the posture of receiving the material roll 200 to the posture of feeding the material roll 20 into the second feeding assembly 20.
