Description

Technical Field

[0001] This application relates to the field of sheet metal processing equipment technology, and in particular to a sheet metal rolling device. Background Technology

[0002] In the field of sheet metal processing, it is sometimes necessary to use rolling devices to roll sheet metal into rolls. Related technologies include common three-roll (one pressure roller and two support rollers) and four-roll (one pressure roller and three support rollers) sheet metal rolling machines. The working principle of the rolling device is as follows: a material passage is formed between the pressure roller and the support rollers for the sheet metal to enter. The rotation of the support roller and the pressure roller drives the sheet metal to rotate, compressing it into an arc shape, thereby processing the sheet metal into a roll that is wound onto the pressure roller.

[0003] For thinner sheets, the roll can be taken directly from the pressure roller through the material passage. However, for thicker sheets, taking the roll out through the material passage will affect the forming effect and performance of the roll, thus affecting the product qualification rate of the roll.

[0004] While some related technologies involve detaching the pressure roller from the base before removing the roll, these solutions typically require the base to be designed as two detachable parts, with the bearing housing installed between these two parts. Each time the pressure roller is removed, multiple connecting parts between the two base parts need to be disassembled, followed by the removal of the bearing housing and the pressure roller. This process involves a large number of disassembled components, resulting in prolonged roll unloading time and low efficiency. Utility Model Content

[0005] This application provides a sheet metal rolling device to solve the problem caused by the unreasonable method of taking out the roll of sheet metal from the pressure roller in the prior art.

[0006] This application provides a sheet metal rolling apparatus, comprising:

[0007] Base;

[0008] At least two support rollers, each of which is rotatably mounted on the base;

[0009] A pressure roller, on which at least one bearing is fitted, is rotatably positioned above the support roller, and a material passage is formed between the pressure roller and the support roller for the material to be rolled to pass through.

[0010] At least one bearing housing, the bearing housing comprising a first housing body and a second housing body disposed opposite to each other on both sides of the bearing, the second housing body being disposed on the base;

[0011] At least one adjusting component is detachably disposed on the base, the adjusting component being configured to drive the first seat body to move such that the first seat body and the second seat body jointly clamp the bearing or release the clamping of the bearing.

[0012] In some possible implementations, the base is provided with a slot, one end of the slot is disposed through the base, and the pressure roller is disposed in the slot through one end of the slot;

[0013] The adjusting assembly confines the pressure roller within the slot.

[0014] In some possible implementations, the adjustment assembly includes a connector and an adjustment member, the connector being detachably connected to the base, the adjustment member being disposed on the connector and corresponding to the first base body, the adjustment member being used to drive the first base body to move.

[0015] In some possible implementations, the adjusting member is rotatably mounted on the connecting member, the end of the adjusting member is provided with a first connecting portion, the outer side of the first seat is provided with a second connecting portion, and the first connecting portion is connected to the second connecting portion.

[0016] In some possible implementations, the first connecting part is a protrusion located at one end of the adjusting member, and the second connecting part is a support groove located on the outside of the first seat body, with the protrusion inserted into the support groove.

[0017] In some possible implementations, the connector is provided with a threaded hole, and the adjusting member is a screw that matches the threaded hole;

[0018] The axial direction of the threaded hole is the same as the direction of movement of the first seat.

[0019] In some possible implementations, the adjustment assembly further includes at least one plug-in that passes through the connector and is plugged into the base.

[0020] In some possible implementations, there are two bearings sleeved on the pressure roller, and the bearing housing and the adjusting assembly are two respectively provided in one-to-one correspondence with the bearings;

[0021] And / or, the first seat and the second seat are respectively disposed on the upper and lower sides of the bearing.

[0022] In some possible implementations, a support base is also included;

[0023] The support includes a first cylinder disposed on the base, a second cylinder slidably disposed on the first cylinder, and an elastic member disposed between the first cylinder and the second cylinder. The elastic member is configured to support the second cylinder, and the second support is disposed on the second cylinder.

[0024] In some possible implementations, a transmission assembly and a drive component are also included;

[0025] The transmission assembly is disposed between two adjacent support rollers and is used to form a transmission connection between the two support rollers.

[0026] The driving element is disposed on one of the support rollers and is used to drive the support roller to rotate.

[0027] The sheet metal rolling device provided in this application drives the first seat to move through an adjusting component, so that the first seat has a clamping state where it and the second seat jointly clamp the bearing, and a separation state where the clamping of the bearing is released. When the first seat is in the clamping state, the sheet metal enters the material passage and is rolled onto the pressure roller by the roller, which facilitates the rolling of the sheet metal into a roll. When the first seat is in the separation state, the pressure roller can be separated from the bearing seat by disassembling the adjusting component and the first seat, and the end of the pressure roller with the bearing can be separated from the base, which facilitates the removal of the roll from the pressure roller. This not only helps to ensure the forming effect and performance of the roll, thus improving the roll qualification rate, but also improves the roll removal efficiency compared to the traditional method of disassembling the pressure roller, which requires disassembling the base, connecting parts and bearing seat.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0050] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.

[0051] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0052] The terms "first," "second," "third," "fourth," etc., used in this application's specification and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0053] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0054] In the prior art, during the processing of sheet metal, a rolling device is usually used to process the sheet metal into a roll. The working principle of these rolling devices is as follows: a material passage 210 is formed between the pressure roller 300 and the support roller 200 to allow the sheet metal to enter. When the support roller 200 and the pressure roller 300 rotate, the sheet metal is gradually rolled into a roll and fitted onto the pressure roller 300 under the squeezing action of the two.

[0055] When removing the roll, for rolls made of thinner sheet materials, the roll can generally be taken out directly from the feed channel 210. However, for thicker sheet materials, removing the roll through the feed channel 210 will adversely affect the forming effect and performance of the roll, thereby reducing the roll's pass rate.

[0056] Although in related technologies, the base 100 is configured as two detachable parts for easy removal of the roll, and the bearing seat 400 is installed between the two parts of the base 100, each time the pressure roller 300 is removed, multiple connecting structures between the two parts of the base 100 need to be disassembled, and then the bearing seat 400 and the pressure roller 300 need to be disassembled. The number of parts that need to be disassembled in the process is large, resulting in long roll unloading time and low efficiency.

[0057] This application provides a sheet metal rolling apparatus, including a base 100, at least two support rollers 200, a pressure roller 300, at least one bearing seat 400, and at least one adjusting component 500.

[0058] Each support roller 200 is rotatably mounted on the base 100. At least one bearing 310 is sleeved on the pressure roller 300, which is rotatably mounted above the support roller 200. A material passage 210 is formed between the pressure roller 300 and the support roller 200 for the material to be rolled to pass through.

[0059] The bearing housing 400 includes a first housing 410 and a second housing 420 disposed opposite to each other on the bearing 310, the second housing 420 being disposed on the base 100. An adjusting assembly 500 is detachably disposed on the base 100, and the adjusting assembly 500 is configured to drive the first housing 410 to move so that the first housing 410 and the second housing 420 together clamp the bearing 310 or release the clamping of the bearing 310.

[0060] The sheet metal rolling device of this application embodiment drives the first seat 410 to move through the adjusting component 500, so that the first seat 410 has a clamping state in which the first seat 410 and the second seat 420 jointly clamp the bearing 310, and a disengaged state in which the clamping of the bearing 310 is released. When the first seat 410 is in the clamping state, the sheet metal enters the material passage 210 and is rolled onto the pressure roller 300 by roller pressing, thereby facilitating the rolling of the sheet metal into a roll. When the first seat 410 is in the disengaged state, it can be disassembled and adjusted. The assembly 500 and the first seat 410 allow the pressure roller 300 to separate from the bearing seat 400, and the end of the pressure roller 300 with the bearing 310 to separate from the base 100, thereby facilitating the removal of the roll from the pressure roller 300. This not only helps ensure the forming effect and performance of the roll, thus improving the roll's pass rate, but also improves the roll removal efficiency compared to the traditional method of disassembling the pressure roller 300, which requires disassembling the base 100, connecting structure, and bearing seat 400.

[0061] The base 100 serves as the mounting carrier for the support roller 200 and the pressure roller 300, as an example of a structure, such as Figure 1 As shown, the base 100 includes two opposing sections 110, each in an "L" shape, which simplifies the structure of the base 100 and facilitates its implementation. The support roller 200 and pressure roller 300 are rotatably mounted on the vertical portions of the two sections 110. It is understood that the base 100 can also be configured in other structural forms according to usage requirements, and no specific limitations are made here.

[0062] In some possible implementations, such as Figure 1 As shown, there are two bearings 310 sleeved on the pressure roller 300, and two bearing seats 400 and two adjusting components 500 respectively corresponding to the bearings 310. This arrangement allows both ends of the pressure roller 300 to be removed from the base 100, facilitating the removal of the roll from either end of the pressure roller 300 and ensuring the forming effect of the roll.

[0063] In some possible embodiments, the bearing 310 is one sleeved on the pressure roller 300. In this case, the bearing housing 400 and the adjusting assembly 500 are arranged corresponding to the bearing 310, and the other end of the pressure roller 300 is directly rotatably mounted on the base 100. This arrangement allows one end of the pressure roller 300 to be removed from the base 100, and the roll can be taken out from one end of the pressure roller 300, which also helps to ensure the forming effect of the roll. In specific implementations, the number of bearings 310, bearing housings 400, and adjusting assemblies 500 can be selected according to the usage requirements.

[0064] In some possible implementations, such as Figure 2As shown, the base 100 is provided with a slot 111, one end of which extends through the base 100. The pressure roller 300 is positioned within the slot 111 via one end of the slot 111, and the adjusting assembly 500 confines the pressure roller 300 within the slot 111. Here, the slot 111 provides installation space for the pressure roller 300, and the through-hole design of one end of the slot 111 facilitates the entry and exit of the pressure roller 300, thereby facilitating the removal of the roll from the pressure roller 300.

[0065] Specifically, slots 111 extend along the height of the base 100 and are disposed on each of the sub-units 110, with the top of the slot 111 being continuous. The bottom wall of the slot 111 is an arc surface, the diameter of which matches the diameter of the pressure roller 300, and the width of the slot 111 also matches the diameter of the pressure roller 300. This arrangement allows the pressure roller 300 to be supported by the bottom wall of the slot 111, and also guides the vertical movement of the pressure roller 300 through the two side walls of the slot 111, thereby improving the stability and ease of movement of the pressure roller 300 within the slot 111.

[0066] The adjusting component 500 restricts the pressure roller 300 within the slot 111, which can further fix the axial position of the pressure roller 300, thereby ensuring the rolling effect of the pressure roller 300 when rolling the sheet material, and thus facilitating the forming of the roll.

[0067] After the roll is wound, the adjusting component 500 is disassembled, releasing it from its restriction on the pressure roller 300. The pressure roller 300 can then move along the slot 111 towards the through end, eventually disengaging from the opening of the slot 111, thus separating the pressure roller 300 from the base 100. At this point, the roll wound on the pressure roller 300 can be moved axially along the pressure roller 300 until it separates from the pressure roller 300, thereby completing the removal of the roll.

[0068] In some possible implementations, such as Figure 1 As shown, the first seat 410 and the second seat 420 are respectively disposed on the upper and lower sides of the bearing 310. This arrangement allows the second seat 420 to not only clamp the outer ring of the bearing 310 in conjunction with the first seat 410, but also to support the pressure roller 300 by supporting the bearing 310, thereby improving the stability of the pressure roller 300 during rotation. After the first seat 410 releases its clamping grip on the bearing 310, the pressure roller 300 can be moved vertically out of the slot 111 by disassembling the adjusting assembly 500.

[0069] In this embodiment, each bearing 310 is located on the outer side of the split body 110, and the bearing housing 400 is also located on the outer side of the base 100, corresponding to the bearing 310. For example... Figure 4 and Figure 5As shown, both the first seat 410 and the second seat 420 are arc-shaped, for example, both are symmetrically arranged semicircles. When the first seat 410 and the second seat 420 abut each other, they define a mounting hole for mounting the bearing 310, thereby clamping the outer ring of the bearing 310. It is understood that even if one or both of the first seat 410 and the second seat 420 are not semicircular, it is still feasible, as long as the clamping effect of the first seat 410 and the second seat 420 meets the requirements.

[0070] In addition, the first base 410 and the second base 420 are respectively provided with radially outward protrusions 411 on both sides in the thickness direction, and the two protrusions 411 and the corresponding bases define a groove. The provision of the protrusions 411 here helps to improve the structural strength of the first base 410 and the second base 420. Of course, it is also feasible to provide protrusions 411 on only one of the first base 410 and the second base 420.

[0071] In some other possible implementations, the first seat 410 and the second seat 420 are respectively disposed on both sides of the bearing 310. In this case, the pressure roller 300 can be supported by the bottom wall of the slot 111 and clamped by the first seat 410 and the second seat 420, which can also meet the needs of the pressure roller 300 for pressing the plate.

[0072] like Figure 1 , Figure 6 and Figure 7 As shown, the adjusting assembly 500 includes a connector 510 and an adjusting member 520. The connector 510 is detachably connected to the base 100, and the adjusting member 520 is disposed on the connector 510 and corresponds to the first seat 410. The adjusting member 520 is used to drive the first seat 410 to move. Here, the connector 510 is detachably connected to the base 100, so that the adjusting assembly 500 can be completely detached from the base 100. In particular, when disassembling the pressure roller 300, removing the connector 510 from the base 100 can release the restriction of the adjusting assembly 500 on the pressure roller 300. The adjusting member 520 is directly disposed on the connector 510 and corresponds to the first seat 410, which also facilitates the applying of downward pressure to the first seat 410 by the adjusting member 520.

[0073] like Figure 6 As shown, the connector 510 is plate-shaped and located on the outside of the vertical portion of the split body 110. Specifically, the connector 510 is detachably connected to the vertical portion of the split body 110. As a connection example, the adjustment assembly 500 also includes at least one plug-in member 530, which passes through the connector 510 and is plugged into the base 100. This plug-in connection of the plug-in member 530 to the base 100 facilitates the installation and removal of the connector 510 from the base 100.

[0074] Reference Figure 1 As shown, two inserts are spaced apart, which facilitates the installation stability of the connector 510 on the split body 110. The connector 530 passes through the connector 510, and corresponding to the connector 530, a corresponding insertion hole 112 is provided on the split body 110. The connector 530 can be interference-fitted into the corresponding insertion hole 112, thereby installing the connector 510 on the corresponding split body 110. When it is necessary to remove the connector 510, the connector 530 can be pulled out from the corresponding insertion hole 112.

[0075] Of course, the connector 510 can also be screwed onto the corresponding split body 110 using multiple bolts, which also facilitates the installation and removal of the connector 510 on the split body 110. In specific implementation, the connection method between the connector 510 and the split body 110 can be determined according to the usage requirements, as long as the detachable connection requirement is met.

[0076] In some possible embodiments, the adjusting member 520 is rotatably mounted on the connecting member 510. The adjusting member 520 has a first connecting portion at its end, and the outer side of the first seat 410 has a second connecting portion. The first connecting portion is connected to the second connecting portion. By rotating the adjusting member 520, the first and second connecting portions are connected, and a compressive force is applied to the first seat 410, causing the first seat 410 and the second seat 420 to cooperate in clamping the bearing 310.

[0077] like Figure 5 and Figure 7 As shown, the first connecting part is a protrusion 521 located at one end of the adjusting member 520, and the second connecting part is a support groove 413 located on the outside of the first seat 410, with the protrusion 521 inserted into the support groove 413. Considering that the first seat 410 is arc-shaped, the connection between the adjusting member 520 and the support groove 413 on the first seat 410 through the protrusion 521 helps to increase the contact area between the protrusion 521 and the support groove 413, thereby improving the stability of the force applied by the adjusting member 520 to the first seat 410.

[0078] In specific implementation, refer to Figure 5 As shown, a mounting groove can be provided at the top of the first base 410, and a support block 412 is inserted into the mounting groove. The support groove 413 is specifically provided on the support block 412. Furthermore, the protrusion 521 can be... Figure 7 The spherical support groove 413 shown in the diagram has a curved surface that matches the shape of the bottom end of the spherical protrusion 521. This arrangement helps ensure the connection between the protrusion 521 and the support groove 413 during the rotation of the adjusting member 520.

[0079] In some possible implementations, such as Figure 6 and Figure 7 As shown, the connecting member 510 is provided with a threaded hole 511, and the adjusting member 520 is a screw that matches the threaded hole 511. The axial direction of the threaded hole 511 is the same as the moving direction of the first seat 410. The adjusting member 520, being a screw, converts the rotational motion of the screw into linear motion in the up-down direction of the first seat 410. Furthermore, the adjusting member 520 acts on the first seat 410, making the displacement of the first seat 410 directly proportional to the rotation angle of the screw. This allows the operator to adjust the moving distance of the first seat 410 by controlling the number of rotations of the screw, thereby adjusting the force applied to the first seat 410 and ultimately adjusting the clamping force of the bearing seat 400 on the bearing 310.

[0080] In addition, the screw drive has a natural self-locking characteristic. When there is no external force driving the screw to rotate, the friction between the screw and the threaded hole 511 can prevent the first seat 410 from moving in the opposite direction due to the reaction force of the bearing 310. During the rolling process, the pressure roller 300 will be subjected to a continuous reaction force transmitted by the sheet material. This force acts on the first seat 410 through the bearing 310, and the self-locking structure between the screw and the threaded hole 511 can offset this reaction force, keeping the first seat 410 in the preset clamping position. This prevents the pressure roller 300 from shifting due to loose clamping, ensures the dimensional stability of the material passage 210, and improves the rolling forming accuracy.

[0081] Furthermore, by aligning the threaded hole 511 with the direction of movement of the first seat 410, the driving force of the screw can be directly transmitted along the direction of movement of the first seat 410 without the need for a force direction conversion structure. This straight force transmission path helps reduce force loss, allowing the torque applied by the screw to be efficiently converted into an axial moving force on the first seat 410. The screw and threaded hole 511 mating structure is simple to operate. To facilitate operation, a handle 522 and other convenient operating structures are provided at the top of the screw.

[0082] like Figure 1 and Figure 6 As shown, the bottom of the connector 510 is provided with an arc-shaped groove 512, which is adapted to the shape of the first seat 410. The bottom of the connector 510 is inserted between the two protrusions 411 on the first seat 410 through the arc-shaped groove 512. This also helps to ensure that the first seat 410 can only move in the vertical direction, which helps to prevent the first seat 410 from deflecting, thereby helping to ensure the cooperation effect of the first seat 410 and the second seat 420.

[0083] In some possible implementations, such as Figure 3 , Figure 8 and Figure 9As shown, the sheet metal rolling apparatus also includes a support base 600. The support base 600 includes a first cylinder 610 disposed on a base 100, a second cylinder 620 slidably disposed on the first cylinder 610, and an elastic member 630 disposed between the first cylinder 610 and the second cylinder 620. The elastic member 630 is configured to support the second cylinder 620, and a second seat 420 is disposed on the second cylinder 620.

[0084] The support base 600, consisting of the first cylinder 610, the second cylinder 620, and the elastic element 630, facilitates the arrangement of the second cylinder 420 on the base 100 and provides good support for the second cylinder 420. In particular, after the first cylinder 410 releases its clamping grip on the bearing 310 and both the first cylinder 410 and the adjusting assembly 500 are disassembled, the pressure roller 300 can be lifted up under the action of the elastic element 630, which also facilitates the removal of the pressure roller 300 from the base 100, thereby making it easier to remove the roll from the pressure roller 300.

[0085] Furthermore, the required support force of the pressure roller 300 varies depending on the thickness of the sheet material during rolling. Thicker sheets require a larger clamping force, necessitating a greater downward pressure on the first support body 410, with increased compression of the elastic element 630 to provide sufficient reaction force. Thinner sheets require a smaller clamping force, requiring less downward pressure on the first support body 410, and less compression of the elastic element 630 to prevent excessive deformation of the sheet material due to overly tight clamping. The elastic support of the elastic element 630 in the support seat 600 adapts to the force requirements under different working conditions without manual adjustment, reducing the need for frequent equipment adjustments due to changes in sheet thickness and thus improving production efficiency.

[0086] like Figure 9 As shown, an arc-shaped connecting piece 631 is provided at the top of the second cylinder 620, and the second cylinder 620 is specifically connected to the second base 420 through the connecting piece 631. Here, the radius of the connecting piece 631 is adapted to the radius of the second base 420, which helps to increase the connection area between the connecting piece 631 and the second base 420, thereby improving the connection strength between the connecting piece 631 and the second base 420.

[0087] To ensure the sliding effect between the first cylinder 610 and the second cylinder 620, such as Figure 9As shown, a radially protruding guide block 611 is provided on the outer periphery of the first cylinder 610, and two guide blocks 611 are arranged opposite each other. A guide groove 621 is provided on the inner periphery of the second cylinder 620, corresponding one-to-one with the guide blocks 611. The guide blocks 611 slide within the corresponding guide grooves 621, thereby ensuring the stability of the second cylinder 620 during vertical sliding. Furthermore, to prevent the second cylinder 620 from detaching from the first cylinder 610, a limiting ring is provided at the bottom end of the second cylinder 620 to stop at the bottom side of the guide block 611. When the limiting block abuts against the guide block 611, the second cylinder 620 moves upward to its highest position.

[0088] In some possible implementations, such as Figure 1 As shown, the sheet metal rolling device also includes a transmission assembly 700 and a drive component 800. The transmission assembly 700 is located between two adjacent support rollers 200, forming a transmission connection between the two support rollers 200; the drive component 800 is located on one of the support rollers 200, driving the support roller 200 to rotate. By driving the support roller 200 to rotate, the drive component 800 drives all the support rollers 200 to rotate, which in turn drives the pressure roller 300 to rotate, thereby achieving the rolling of the sheet metal.

[0089] In practical implementation, the number of support rollers 200 can be: Figure 2 The two shown can also be multiple. The transmission assembly 700 includes gears 710 disposed between the same ends of each support roller 200, and a chain 720 wound around the two gears 710 and meshing with them. The transmission effect of the gears 710 and chain 720 in this configuration is stable and reliable.

[0090] Of course, the transmission assembly 700 can also be a transmission belt wound between the same ends of the two support rollers 200, as long as the transmission requirements are met.

[0091] like Figure 1 As shown, the drive component 800 can be a crank handle disposed at one end of the support roller 200, and the structure of the crank handle is not limited to... Figure 1 As shown in the diagram, the support roller 200 is rotated by manually driving the drive component 800 to roll the sheet metal, which helps reduce production costs. Of course, the drive component 800 can also be a drive motor or the like capable of outputting rotational driving force, in which case the sheet metal can be rolled automatically, which helps improve processing efficiency.

[0092] When using the sheet metal rolling device in this embodiment, the sheet metal to be rolled is first loaded into the feed channel 210, where it is supported by two support rollers 200. Then, the adjusting member 520 is rotated so that the bottom end of the adjusting member 520 presses down on the first seat 410 until the first seat 410 and the second seat 420 clamp the bearing 310, and the pressure roller 300 presses the sheet metal tightly.

[0093] Then, the drive unit 800 is manually rotated, causing the support roller 200 and pressure roller 300 to rotate. The clamped sheet material moves accordingly and is rolled into an arc shape until it is rolled into a cylinder fitted outside the pressure roller 300. If the shape of the cylinder is not ideal, the forming effect can be improved by multiple rolling processes. For example, the two overlapping sides of the cylinder can be connected together by spot welding, and the cylinder can be formed by multiple rolling processes.

[0094] When it is necessary to remove the drum, first rotate the adjusting member 520 in the reverse direction to separate the protrusion 521 on the adjusting member 520 from the support groove 413. Then, separate the connector 530 from the base 100, so that the adjusting member 520 is removed from the base 100. Then, remove the first seat body 410. Next, lift the pressure roller 300 upward so that the pressure roller 300 disengages from the slot 111. Finally, remove the drum from the pressure roller 300. If the bearing 310 obstructs the removal of the drum, the bearing 310 can be removed from the pressure roller 300 before removing the drum.
