Description

Technical Field

[0001] The present application relates to the field of laminating technology, and in particular to a device for laminating color films that facilitates switching of laminating rollers. Background Art

[0002] Color film laminating equipment refers to equipment that coats the surface of a substrate with a colored film. Depending on the type of substrate, the laminating equipment will also vary. With the development of the color steel industry in recent years, the application areas of color steel have become wider and wider, and the requirements for color film laminating equipment for steel plates have also become higher and higher.

[0003] Current color film laminating equipment generally includes a base frame, laminating rollers and support rollers that are arranged vertically and connected to the base frame for horizontal rotation. During operation, the steel plate and the color film pass through the laminating rollers and support rollers at the same time. Through the preheating of the steel plate and / or the heatable lamination, the color film and the steel plate are thermally laminated. Due to the different materials of the color film to be coated, the steel plate laminating equipment often needs to prepare steel laminating rollers and rubber laminating rollers. The rubber laminating roller is a laminating roller with a rubber surface to meet the laminating requirements of different color films. Therefore, the connection between the laminating roller and the base frame is usually detachable, so that the operator can remove the laminating roller from the base frame for replacement.

[0004] The above-mentioned laminating equipment that requires multiple laminating rollers basically needs to be stopped and replaced manually when replacing them. However, since the laminating rollers are generally large in size and weight, at least two operators are often required to operate them during installation and disassembly. In addition, the operation is relatively cumbersome and the replacement time is long.

[0005] Therefore, it is urgent to provide a color film laminating device that is easy to replace the laminating roller, so as to facilitate the replacement of the laminating film, save labor costs and improve replacement efficiency. Summary of the Invention

[0006] In order to facilitate the replacement of the coating, save labor costs and improve replacement efficiency, the present application provides a color film coating device that is easy to replace the coating roller.

[0007] The present application provides a color film laminating device that is easy to replace the laminating roller, which adopts the following technical solution:

[0008] A color film laminating device that is convenient for replacing laminating rollers, comprising: a base frame, a support roller horizontally rotatably arranged on the base frame;

[0009] The base frame is provided with two opening and closing receiving plates at a position above one end portion corresponding to the supporting roller, and the adjacent sides of the two receiving plates are provided with receiving half holes which can form a receiving hole when closed;

[0010] The base frame is provided with a socket on the side opposite to the receiving plate, and further comprises:

[0011] The carrier frame is in situ turnable and arranged on the side of the base frame close to the receiving plate along the axis direction of the supporting roller;

[0012] Two clamping and conveying devices are respectively arranged on the upper and lower surfaces of the carrier frame and can move along the axis direction of the supporting roller;

[0013] The two coating rollers are clamped by two clamping and conveying devices along the axial direction of the supporting roller. The clamping and conveying devices can drive the coating rollers in and out of the base frame on the receiving plate. After the coating rollers enter the base frame, they can be received between the receiving hole and the insertion hole.

[0014] When the film roller needs to be replaced, the laminating roller is moved to the position corresponding to the receiving plate by the carrier frame, the two carrier plates are opened, and then the laminating roller is dragged to move by the clamping and conveying device of the specified laminating roller, so that the laminating roller can be sent to the base frame. First, one end of the laminating roller is inserted into the insertion hole, and then the two receiving plates are closed, so that the other end of the laminating roller is inserted into the receiving hole to complete the installation of the laminating roller. When the film roller needs to be replaced, the carrier plate is flipped in situ, the surface that does not clamp the laminating roller faces upward, and then the clamping and conveying device moves toward the base frame, and the clamping and conveying device clamps one end of the laminating roller to be replaced, and then the two receiving plates are opened, and the clamping and conveying device drags the laminating roller out of the base frame and places it on the receiving frame, and then the carrier frame is flipped in situ until the laminating roller is located at the lower side of the carrier frame, and then another laminating roller is sent to the base frame for installation by another clamping and conveying device.

[0015] Optionally, the support roller is vertically and liftably arranged on the base frame, further comprising:

[0016] The receiving roller is rotatably arranged in the base frame along the axis direction of the supporting roller and is located on the side of the base frame corresponding to the installation position of the laminating roller. The receiving roller is wrapped with a receiving belt;

[0017] The traction roller is movably arranged in the base frame along the axial direction of the receiving roller. The traction roller can move along the lower circumference of the coating roller on the base frame with the receiving roller position as the starting point to the other side of the base frame corresponding to the coating roller installation position. The end of the receiving belt facing away from the receiving roller is fixed to the traction roller.

[0018] By adopting the above technical solution, when the receiving roller needs to be disassembled, the support roller moves vertically downward to increase the distance between the support roller and the receiving roller in the base frame, and then the traction roller drives the receiving belt from the position of the receiving roller as the starting point to move along the lower circumference of the coating roller on the base frame to the other side of the base frame corresponding to the coating roller installation position. At this time, the receiving belt can receive the lower circumference of the receiving roller. At this time, when the clamping and conveying device drags the coating roller to move, and the end of the coating roller is separated from the socket of the base frame, the receiving belt can receive the coating roller, reducing the burden on the traction and holding device. Similarly, when the other coating roller is sent into the base frame, the receiving belt will also receive the receiving roller to ensure the support of the receiving roller.

[0019] Optionally, the clamping and conveying device includes:

[0020] The clamping arms are V-shaped and are arranged on both sides of the carrier along the axis of the support roller. The arc openings of the clamping arms on both sides are arranged opposite to each other to limit the relative position of the laminating roller and the carrier;

[0021] The sliding arm is movably arranged on the supporting frame along the axis direction of the supporting roller;

[0022] The clamping component is arranged on the sliding arm and is used for clamping the shaft end of the laminating roller.

[0023] By adopting the above technical solution, when installing the coating roller, the sliding arm drives the clamping component to move to the end of the base frame corresponding to the coating roller, and clamps one end of the coating roller through the clamping component. Then, the two supporting plates are opened, and the clamping component is driven to move by the sliding arm, so that the support roller can be dragged out of the inside of the base frame.

[0024] Optionally, both ends of the base frame corresponding to the traction roller are formed with arc grooves along the movement trajectory of the traction roller;

[0025] Slide blocks are slidably arranged in the arc-shaped grooves, and both ends of the traction roller are connected to the slide blocks;

[0026] A winding drive member is provided in the slider for driving the traction roller to rotate;

[0027] A sliding drive member is provided between the slider and the base frame for driving the slider to move.

[0028] By adopting the above technical solution, the slider is driven to move by sliding, so that the slider can slide along the arc groove, thereby driving the traction roller to move, and driving the receiving belt to be stretched to the lower side of the coating roller, and then the traction roller is driven to rotate by the winding drive member, so that the receiving belt can be wound and tightened, so that the receiving belt abuts against the lower side of the coating roller to receive the coating roller.

[0029] Optionally, the sliding drive member includes:

[0030] A rack is arranged on one side of the arc groove along the trajectory of the arc groove;

[0031] A driving gear is rotatably mounted on the slider, wherein the driving gear is engaged with the rack;

[0032] The rotary driving member is fixed to the slider and is used to drive the gear to rotate.

[0033] By adopting the above technical solution, during operation, the rotating driving member drives the driving gear to rotate, which can make the driving gear roll along the rack, thereby driving the slider to move along the arc groove to realize the movement of the traction roller.

[0034] Optionally, also include:

[0035] A slide is movably arranged on the base frame along the axis direction of the support roller, and the slide is located above the installation position of the laminating roller;

[0036] The auxiliary clamping member is arranged on the lower side of the slide and is used to clamp the end of the laminating roller.

[0037] By adopting the above technical solution, when the coating roller needs to be disassembled, the auxiliary clamping member is driven to move by the slide, so that the auxiliary clamping member clamps the coating roller and is inserted into one end of the socket, and then the other end of the coating roller is clamped by the clamping and conveying device. The coating roller is driven to move by the clamping and conveying device in cooperation with the auxiliary clamping member, so that the coating roller can be smoothly moved in and out of the base frame.

[0038] Optionally, also include:

[0039] A lead screw is rotatably arranged on the base frame along the axis direction of the support roller and is located above the installation position of the laminating roller. The slide is threadedly connected to the lead screw.

[0040] The rotation driving member is arranged on the base frame and is used for driving the lead screw to rotate.

[0041] By adopting the above technical solution, the rotating driving member drives the lead screw to rotate, which can drive the slide to slide, thereby adjusting the position of the auxiliary clamping member to complete the movement of the auxiliary clamping member to meet work requirements.

[0042] Optionally, also include:

[0043] A support shaft is rotatably arranged on a side of the carrier frame away from the base frame;

[0044] One end of the support member is connected to the base frame, and the other end is connected to the support shaft.

[0045] By adopting the above technical solution, the support shaft is supported by the support member, so that the end of the supporting frame away from the base frame can be supported, thereby ensuring the bearing capacity of the supporting frame. Moreover, since the support shaft is rotatably arranged on the supporting frame, when the supporting frame rotates, the support shaft can maintain the support of the supporting frame.

[0046] Optionally, also include:

[0047] A universal coupling is fixed between the base frame and the carrier frame;

[0048] The supporting member is a telescopic cylinder.

[0049] By adopting the above technical solution, through the cooperation of the universal coupling and the telescopic cylinder, when the telescopic cylinder contracts, it can drive the carrier frame to swing downward to an inclined state, so that when the non-coated roller is replaced, the carrier frame can be swung to an inclined state to reduce the space occupied by the equipment and facilitate the movement of operators.

[0050] In summary, this application includes at least one of the following beneficial technical effects:

[0051] When the film roller needs to be replaced, the film roller is moved to the position corresponding to the receiving plate by the carrier frame, the two carrier plates are opened, and then the film roller is dragged to move by the clamping and conveying device of the specified film roller, so that the film roller can be sent to the base frame. First, one end of the film roller is inserted into the insertion hole, and then the two receiving plates are closed, so that the other end of the film roller is inserted into the receiving hole to complete the installation of the film roller. When the film roller needs to be replaced, the carrier plate is flipped in situ, and the surface of the film roller not clamped is facing upward, and then the clamping and conveying device moves toward the base frame, and clamps one end of the film roller to be replaced by the clamping and conveying device, and then the two receiving plates are opened, and the clamping and conveying device drags the film roller out of the base frame and places it on the receiving frame, and then the carrier frame is flipped in situ until the film roller is located at the lower side of the carrier frame, and then another film roller is sent to the base frame for installation by another clamping and conveying device.

[0052] 2. When the receiving roller needs to be removed, the support roller moves vertically downward to increase the distance between the receiving rollers in the support roller base frame, and then the traction roller drives the receiving belt to move from the position of the receiving roller as the starting point along the lower circumference of the coating roller on the base frame to the other side of the base frame corresponding to the coating roller installation position. At this time, the receiving belt can receive the lower circumference of the receiving roller. At this time, when the clamping and conveying device drags the coating roller to move, and the end of the coating roller is separated from the socket of the base frame, the receiving belt can receive the coating roller, reducing the burden on the traction and holding device. Similarly, when the other coating roller is sent into the base frame, the receiving belt will also receive the receiving roller to ensure the support of the receiving roller.

[0071] The following is combined with Figure 1-9 This application is described in further detail.

[0072] In the embodiment of the present invention, the process of replacing the laminating roller 1 includes two laminating rollers 1 .

[0073] Both laminating rollers 1 consist of a barrel and a shaft. The barrel serves as the working portion. The two laminating rollers 1 are respectively a steel roller and a rubber roller. The steel roller is integrally formed from steel. The rubber roller and steel roller have essentially the same structure, differing primarily in that the working portion of the rubber roller is laminated with a rubber layer. The choice of steel or rubber roller depends on the color film being laminated to the steel plate.

[0074] The embodiment of the present application discloses a color film laminating device that is easy to replace the laminating roller.

[0075] Example 1:

[0076] Reference Figure 1 A color film laminating device that is easy to replace the laminating roller includes a base frame 2, a supporting roller 3 arranged on the base frame 2, and a laminating roller replacement device arranged on the base frame 2.

[0077] The base frame 2 is vertically arranged as a whole, and includes a horizontally arranged base 21. The base 21 is in the shape of a long plate. Both ends of the base 21 are vertically fixed with mutually parallel side plates 22, and the upper ends of the two side plates 22 are horizontally fixed with crossbeams 23.

[0078] The support roller 3 is horizontally arranged between the two side plates 22. The positions of the two side plates 22 corresponding to the support roller 3 are vertically slidably connected with the lifting plates 221. The two ends of the support roller 3 are respectively rotatably connected to the two lifting plates 31. The lower parts of the two side plates 22 corresponding to the lifting plates 31 are vertically fixed with distance adjusting cylinders 221, and the telescopic rods of the two distance adjusting cylinders 221 are fixed to the lifting plates 31.

[0079] During operation, the two distance adjustment cylinders 221 drive the telescopic rod to extend and retract, thereby pushing the two lifting plates 31 to rise or fall synchronously, thereby realizing the height adjustment of the support roller 3 to meet different work requirements.

[0080] Reference Figure 1 and Figure 2, one side plate 22 of the base frame 2 corresponds to the upper position of the support roller 3, that is, the installation position of the laminating roller 1 is provided with a through groove 222, and two receiving plates 24 are provided on one side of the side plate 22 corresponding to the position of the through groove 222. The two receiving plates 24 slide horizontally on the side plate 22, and a two-way adjustment cylinder 25 is fixed on one side of the side plate 22 corresponding to the two receiving plates 24. The two telescopic rods of the two-way adjustment cylinder 25 are respectively fixed to the two receiving plates 24. The two-way adjustment cylinder 25 drives the two telescopic rods to contract, which can drive the two receiving plates 24 to move towards each other, so that the two receiving plates 24 close the through groove 222, and useful receiving half holes 241 are symmetrically provided on the adjacent side of the two receiving plates 24. When the two receiving plates 24 move relative to each other until they abut each other, the two receiving half holes 241 can be spliced ​​into a receiving hole. The other side plate 22 of the base frame 2 is formed with a socket 223 at the position corresponding to the receiving hole. The socket 223 and the receiving hole are coaxially arranged. The two ends of the coating roller 1 can be respectively inserted into the socket 223 and the receiving hole and extend out of the socket 223 and the receiving hole, thereby realizing the rotation setting of the coating roller 1 in the base frame 2.

[0081] Reference Figure 3 Furthermore, in order to facilitate the rotation of the coating roller 1, a driving element 26 can be fixed on the outer side of the side plate 22 with the socket 223. The driving element 26 adopts a driving motor, and the output shaft of the driving motor is fixed with a spline head 261. The shaft end of the coating roller 1 can be formed with a spline sleeve 11. In this way, when the coating roller 1 is installed on the base frame 2, one end of the spline sleeve 11 of the coating roller 1 will be simultaneously plugged into the spline head 261 of the driving motor, thereby realizing the docking of the coating roller 1 and the driving motor, so that the driving motor can drive the coating roller 1 to rotate.

[0082] Reference Figure 1 and Figure 4 The coating roller replacement device is arranged on one side of the base frame 2, and includes a carrier frame 4. The carrier frame 4 is a horizontally arranged long frame structure as a whole. The length direction of the carrier frame 4 is the same as the length direction of the base 21 of the base frame 2. One end of the carrier frame 4 is rotatably arranged on the base frame 2, and the end of the carrier frame 4 away from the base frame 2 is rotatably connected to the support shaft 41. The support shaft 41 and the rotation axis of the carrier frame 4 and the rotation axis of the carrier frame 4 and the base frame 2 are in the same straight line.

[0083] Reference Figure 1 and Figure 4 A tilted support frame 27 is fixed between the support shaft 41 and the base frame 2 to support the end of the receiving frame away from the base frame 2. A first reciprocating motor 42 is fixed to the end of the support shaft 41 away from the carrier frame 4. The output shaft of the first reciprocating motor 42 is fixed to the carrier frame 4. When the first reciprocating motor 42 rotates, it can drive the carrier frame 4 to flip in place.

[0084] Reference Figure 4The upper and lower surfaces of the carrier frame 4 are both provided with clamping and conveying devices, which are respectively used to clamp and convey the coating roller 1. Specifically, the clamping and conveying devices include a clamping component 5 and a pushing component 6. The clamping component 5 includes clamping arms 51 provided on both sides of the carrier frame 4 along the length direction of the carrier frame 4. The clamping arms 51 are all V-shaped, and the arc openings of the clamping arms 51 on both sides of the carrier frame 4 are arranged relative to each other. A contraction element is also provided on the carrier frame 4, which is used to realize the relative or opposite movement of the clamping arms 51 on both sides of the carrier frame 4. Specifically, the contraction element can be a bidirectional adjustment cylinder. That is, a bidirectional adjustment cylinder is fixed between the two corresponding opposite clamping arms 51 of the carrier frame 4. The telescopic rods of the bidirectional adjustment cylinder are respectively fixed to the two clamping arms 51. By driving the telescopic rod to extend and retract by the bidirectional adjustment cylinder, the two clamping arms 51 can be driven to move relative or opposite to each other, thereby realizing the clamping and receiving of the coating roller 1.

[0085] Furthermore, in order to facilitate the movement of the coating roller 1 along the length direction of the carrier frame 4 when clamped by the clamping arm 51, a roller (not shown in the figure) is rotatably provided on the side of the clamping arm 51 that can contact the coating roller 1, and the axial direction of the roller is perpendicular to the length direction of the carrier frame 4. In this way, when the clamping arm 51 clamps the coating roller 1, the coating roller 1 can still move smoothly along the length direction of the carrier frame 4, so that the pushing component 6 can push the coating roller 1 through the two receiving plates 24 into the base frame 2.

[0086] Reference Figure 4 The pushing component 6 includes a sliding arm 61 and a main clamping member 62. The sliding arm 61 slides on the supporting frame 4 along the length direction of the supporting frame 4. Screws 63 are provided on both sides of the supporting frame 4 for rotation along its length direction. The sliding arm 61 is threadedly connected to the screw 63. A second reciprocating motor is also fixed to one end of the supporting frame 4 corresponding to the screw 63. The second reciprocating motor drives the screw 63 to rotate to realize the reciprocating movement of the sliding arm 61 along the supporting frame 4. The main clamping members 62 are fixed on the side of the sliding arm 61 close to the supporting frame 4. The main clamping members 62 can adopt pneumatic clamps or electric clamps.

[0087] Reference Figure 4 In this way, one end of the coating roller 1 is clamped by the main clamping member 62, and then the main clamping member 62 is driven to move by the sliding arm 61, so that the coating roller 1 can be pulled to reciprocate along the length direction of the carrier frame 4, so that after the two receiving plates 24 are opened, the coating roller 1 can be pushed into the base frame 2, and then the two receiving plates 24 move relative to each other, so that the two ends of the coating roller 1 are respectively inserted into the insertion hole 223 and the receiving hole.

[0088] Furthermore, in order to realize the support of the laminating roller 1 during the installation process of the laminating roller 1 and reduce the burden of the clamping and conveying device, an auxiliary support device 7 can also be provided, which is described in detail below:

[0089] Reference Figure 5 and Figure 6 The auxiliary carrying device includes a receiving roller 71, the axial direction of the receiving roller 71 is the same as the axial direction of the supporting roller 3, the two ends of the receiving roller 71 are rotatably connected to the two side plates 22, and the receiving roller 71 is located on the side of the installation position of the coating roller 1 in the base frame 2. Specifically, the axis of the receiving roller 71 can be in the same horizontal plane as the axis of the receiving roller 71 in the base frame 2, and a receiving belt 72 is wrapped around the receiving roller 71. A traction roller 73 is provided on the side of the receiving roller 71 close to the installation position of the coating roller 1. The axial direction of the traction roller 73 is the same as the axial direction of the receiving roller 71, and the end of the receiving belt 72 facing away from the receiving roller 71 is fixed to the traction roller 73, and the two side plates 22 are formed with arc grooves 224 along the lower side of the circumference of the coating roller 1 on the base frame 2 at the two end positions corresponding to the traction roller 73. Sliders 74 are slidably connected within the two arcuate grooves 224. The ends of the traction roller 73 are rotatably connected to the two slides 74. A winding drive element, such as a drive motor, is fixed to one of the slides 74 to drive the traction roller 73 to reciprocate. A sliding drive element is also provided between the slide 74 and the base frame 2 to drive the slide 74 to slide along the arcuate groove 224.

[0090] When the laminating roller 1 needs to be replaced, the supporting roller 3 moves vertically downward, and then the sliding drive member drives the slider 74 to move along the arc groove 224, thereby driving the traction roller 73 to move along the lower circumference of the laminating roller 1, so that the receiving belt 72 starts from the position of the receiving roller 71 and moves along the lower circumference of the laminating roller 1 on the base frame 2 to the other side of the base frame 2 corresponding to the installation position of the laminating roller 1, so that the receiving belt 72 is unfolded on the lower side of the laminating roller 1, and then the traction roller 73 is driven to rotate by the winding drive member. , driving the receiving belt 72 to be wound and tightened, so that the receiving belt 72 abuts against the lower side of the coating roller 1, thereby supporting the coating roller 1. At this time, when the clamping and conveying device drags the coating roller 1 and moves until the end of the coating roller 1 is out of the socket 223 of the base frame 2, the receiving belt 72 can support the coating roller 1, reducing the burden on the traction and holding device. Similarly, when another coating roller 1 is sent into the base frame 2, the receiving belt 72 will also support the receiving roller 71 to ensure the support of the receiving roller 71.

[0091] Reference Figure 6 and Figure 7 The sliding drive member specifically includes a rack 225 fixed to one side of the arcuate groove 224 along the trajectory of the arcuate groove 224, and a drive gear 75 rotatably connected to the slider 74. The drive gear 75 is engaged with the rack 225, and a rotary drive member 76, such as a drive motor, is fixed to the slider 74 to drive the gear 75 to reciprocate. In this way, the rotary drive member 76 drives the drive gear 75 to rotate, causing the drive gear 75 to roll along the rack 225, thereby driving the slider 74 to move along the arcuate groove 224, thereby achieving the movement of the traction roller 73.

[0092] The implementation principle of this embodiment is:

[0093] When replacing the film roller 1, the support roller 3 is lowered, and the slider 74 drives the traction roller 73 to move, so that the receiving belt 72 is located at the lower side of the film roller 1 to receive the film roller 1, and then the slide arm 61 of the clamping conveyor device moves, so that the main clamping member 62 of the slide arm 61 clamps one end of the film roller 1, and then the two receiving plates 24 are opened, and the carrier frame 4 is driven to move by the slide arm 61, and the film roller 1 is dragged toward the carrier frame 4 so that the film roller 1 is dragged onto the carrier frame 4. During the movement of the film roller 1, the clamping arms 51 on both sides of the carrier frame 4 can always achieve the film roller 1 The receiving frame is then turned 180 degrees to drive the other coating roller 1 to rotate to the upper side, and then the main clamping member 62 on the upper side of the carrier frame 4 clamps the coating roller 1 on the upper side of the carrier frame 4, and the sliding arm 61 pushes the coating roller 1 to move along the carrier frame 4, so that the coating roller 1 can be sent to the base frame 2 through the two receiving plates 24. At this time, the receiving belt 72 will realize the receiving of the lower side of the coating roller 1 until one end of the coating roller 1 is inserted into the insertion hole 223, and then the two receiving plates 24 are closed to make the other end of the coating roller 1 inserted into the receiving hole to complete the installation of the coating roller 1.

[0094] Example 2:

[0095] A color film laminating device that is convenient for switching the laminating roller 1 is different from the first embodiment in that an auxiliary clamping device 8 is further provided for realizing the installation and disassembly of the auxiliary laminating roller 1 and reducing the workload of the clamping and conveying device.

[0096] Reference Figure 8 Specifically, the auxiliary clamping device 8 includes a sliding shaft 81 arranged in the frame body along the axial direction of the support shaft 41, the sliding shaft 81 is located on the upper side of the installation position of the coating roller 1, and the two ends of the sliding shaft 81 are fixed to the two side plates 22, and a slide 82 slides on the sliding shaft 81. A screw 83 with the same axial direction as that of the sliding shaft 81 is also provided on one side of the sliding shaft 81. Both ends of the screw 83 are rotatably connected to the side plates 22, and the slide 82 is threadedly connected to the screw 83. A rotating driving member such as a motor is fixed on one side plate 22 for driving the screw 83 to rotate, so that the slide 82 can reciprocate along the slide 82.

[0097] Reference Figure 8 A lifting cylinder 84 is vertically provided on the lower side of the slide 82 , and an auxiliary clamping member 85 is fixed to the lower end of the lifting cylinder 84 , and the auxiliary clamping member 85 can be a pneumatic clamping claw.

[0098] Compared with Example 1, the difference between this embodiment is that: when the coating roller 1 needs to be disassembled, the auxiliary clamping member 85 is driven to move horizontally by the slide 82, and the auxiliary clamping member 85 is driven to move vertically by the lifting cylinder 84, so that the auxiliary clamping member 85 clamps the coating roller 1 and is inserted into the circumference of one end of the insertion hole 223, and then clamps the other end of the coating roller 1 with the clamping and conveying device. The coating roller 1 is driven to move by the clamping and conveying device and the auxiliary clamping member 85, so that the coating roller 1 can smoothly enter and exit the base frame 2.

[0099] Example 3:

[0100] Reference Figure 9 , a color film laminating device that is easy to switch the laminating roller 1, which differs from Example 1 in that:

[0101] A universal coupling 43 is fixed between the side plate 22 and the carrier frame 4 , and in this embodiment, a telescopic cylinder 28 is used instead of the support frame 27 , the cylinder body of the telescopic cylinder 28 is hinged to the base frame 2 , and the telescopic rod of the telescopic cylinder 28 is hinged to the support shaft 41 .

[0102] Compared with Example 1, the advantage is that: by adopting the cooperation of the universal coupling 43 and the telescopic cylinder 28, when the telescopic cylinder 28 contracts, it can drive the carrier frame 4 to swing downward to an inclined state, so that when the non-coated roller 1 is replaced, the carrier frame 4 can be swung to an inclined state to reduce the space occupied by the equipment and facilitate the movement of operators.

[0103] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
