Description

Technical Field

[0001] This utility model belongs to the technical field of roller replacement for aluminum foil winding, and specifically relates to a quick-change structure for rollers used in winding machines. Background Technology

[0002] In the production of aluminum foil, a winding machine is needed to wind the produced aluminum foil into rolls. To improve the efficiency of the winding process, the connection between the winding machine and the roll is designed as a quick-change structure. While existing quick-change structures for winding machines meet the basic requirement of quick roll changes and allow for assisted vertical movement of the roll via auxiliary support structures, making roll replacement easier and less strenuous for users, these auxiliary support structures are often only suitable for rolls of a single length. When the roll's dimensions change, it is often time-consuming and laborious to disassemble and reinstall the auxiliary support structure before it can continue to support the roll, thus causing significant inconvenience for users.

[0003] For example, the utility model with announcement number CN220925765 discloses an aluminum foil winding device that facilitates the replacement of winding rollers. Although it can meet the basic requirement of easy replacement of winding rollers, the lifting mechanism, which is fixedly set on the support platform, assists in lifting the winding rollers. The lifting length of the lifting mechanism is fixed, which means that it can only provide auxiliary support for winding rollers of a specific length. When the length of the winding rollers changes, it is necessary to spend time and effort to adjust the positions of the support frame, electric push rod and arc bracket before the winding rollers can continue to be effectively supported. Therefore, it cannot fully meet people's needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a quick-change structure for winding rollers in a winding machine. This structure not only meets the basic requirement of quick replacement of winding rollers, but also allows for flexible and convenient adjustment of the support width of the auxiliary support structure, thereby fully meeting the winding requirements of winding rollers with different axial lengths.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a quick-change structure for a winding machine roller, including a base, a mounting groove provided on the top of the base, a bidirectional screw rotatably disposed between the left and right ends of the mounting groove, mounting blocks slidably connected to the mounting groove being screwed to both sides of the bidirectional screw, support plates vertically disposed on the two mounting blocks, connecting shafts horizontally penetrating and rotatably disposed on the two support plates, fixing blocks being disposed on the inner ends of the two connecting shafts, and fixing cylinders adapted to the fixing blocks being disposed at both ends of the winding roller. Both the vertical cross-section of the fixed insert and the inner hole are non-circular. The base is also equipped with a U-shaped fixing frame that spans the mounting groove in the front-to-back direction. Guide inserts are slidably installed on the left and right sides of the top of the fixing frame. A telescopic push rod is vertically installed at the middle of the top of the fixing frame. A crossbar is installed at the upper end of the output shaft of the telescopic push rod. A cross cylinder is installed at both ends of the crossbar. Limiting bolts that can abut against the crossbar are also installed on the two cross cylinders. Arc-shaped support blocks that are adapted to the fixed insert are installed on the two cross cylinders through connecting rods. A guide rod that is vertically inserted into the guide insert is installed at the bottom of the cross cylinder.

[0006] As a further improvement of this utility model, a first drive motor for rotating the bidirectional screw is provided at the right end of the mounting groove, and first bearings rotatably connected to the two sides of the bidirectional screw are provided on both sides of the mounting groove. The right end of the bidirectional screw extends to the outside of the mounting groove, and a U-shaped mounting bracket is also provided at the right end of the mounting groove. The first drive motor is mounted on the mounting bracket, and the right end of the bidirectional screw is connected to the output shaft of the first drive motor through a coupling.

[0007] As a further improvement of this utility model, a second drive motor is arranged horizontally on a support plate, a drive gear is arranged on the output shaft of the second drive motor, and a driven gear that meshes with the drive gear is arranged near the output shaft of the second drive motor.

[0008] As a further improvement of this utility model, connecting grooves are respectively provided on the left and right sides of the top of the fixing frame, and a connecting slider is provided at the bottom of the guide tube to slide in connection with the connecting groove. The sliding hole of the connecting groove and the vertical section of the connecting slider are both T-shaped.

[0009] As a further improvement of this utility model, the top left and right sides of the base are also provided with extended sliding grooves located on the front and rear sides of the mounting groove, and the front and rear ends of the support plate are also provided with extended sliders that are slidably connected to the extended sliding grooves. The sliding holes of the extended sliding grooves and the vertical cross sections of the extended sliders are both T-shaped.

[0010] As a further improvement of this utility model, scale lines are also provided on both sides of the crossbar. The scale lines allow for convenient and precise control of the adjustment position of the cross cylinder relative to the crossbar.

[0011] As a further improvement of this utility model, an extension plate is also provided at the bottom side of the base, and anchor bolts for connecting to the ground are also provided on the extension plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the limiting bolts can be loosened to release the fixation at the connection between the cross cylinder and the crossbar. Then, the cross cylinder, guide cylinder, guide rod, and arc-shaped support block can slide left and right corresponding to the telescopic push rod, so that the position of the arc-shaped support block meets the support requirements of the winding roller of the corresponding axial length. After that, the limiting bolts can be tightened again to re-fix the connection between the cross cylinder and the crossbar. This facilitates and fully meets the needs of lifting and adjusting winding rollers of different axial lengths.

[0014] Secondly, the sliding connection between the guide tube and the fixed frame can be achieved through the cooperation of the connecting groove and the connecting slider; and because the sliding hole of the connecting groove and the vertical section of the connecting slider are both T-shaped, the vertical offset of the connecting slider relative to the connecting groove can be avoided.

[0015] Thirdly, the extension groove and the extension slider work together to provide auxiliary support for the support plate, so that the support plate can slide and adjust smoothly, and the support plate can also have better stability during the sliding adjustment process.

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 3 As shown in Figure 4, a quick-change structure for a winding machine includes a base 101. The top of the base 101 is provided with a mounting groove 102. A bidirectional screw 103 is rotatably provided between the left and right ends of the mounting groove 102. Mounting blocks 104 that are slidably connected to the mounting groove 102 are screwed to both sides of the bidirectional screw 103. Support plates 105 are vertically provided on the two mounting blocks 104. Connecting shafts 106 are horizontally penetrating and rotatably provided on the two support plates 105. Fixed inserts 107 are provided on the inner ends of the two connecting shafts 106. Fixed inserts 108 that are adapted to the fixed inserts 107 are provided at both ends of the winding roller 100. The vertical cross-section of the inner hole of the fixed inserts 107 and the fixed inserts 108 are both square.

[0024] The base 101 is also provided with a U-shaped fixing frame 109 that spans the mounting groove 102 in the front-to-back direction. Guide tubes 110 are slidably provided on the left and right sides of the top of the fixing frame 109. A telescopic push rod 111 is vertically provided at the middle of the top of the fixing frame 109. A crossbar 112 is provided at the upper end of the output shaft of the telescopic push rod 111. A cross cylinder 113 is provided at both ends of the crossbar 112. Limiting bolts 114 that can abut against the crossbar 112 are also provided on the two cross cylinders 113. Arc-shaped support blocks 115 that are adapted to the fixing tube 108 are provided on the two cross cylinders 113 through connecting rods 123. Guide tubes 116 that are vertically inserted into the guide tubes 110 are provided at the bottom of the cross cylinders 113. A second bearing is provided on the support plate 105. The outer ring of the second bearing is connected to the support plate 105, and the inner ring of the second bearing is connected to the outer wall of the connecting shaft 106.

[0025] like Figure 1 As shown, a first drive motor 117 for rotating the bidirectional screw 103 is provided at the right end of the mounting groove 102. First bearings 118 are provided on both sides of the mounting groove 102 and rotatably connected to both sides of the bidirectional screw 103. The right end of the bidirectional screw 103 extends to the outside of the mounting groove 102. A U-shaped mounting bracket is also provided at the right end of the mounting groove 102. The first drive motor 117 is mounted on the mounting bracket. The right end of the bidirectional screw 103 is connected to the output shaft of the first drive motor 117 through a coupling 119.

[0026] like Figure 1 As shown, a second drive motor 120 is horizontally arranged on a support plate 105. A drive gear 121 is arranged on the output shaft of the second drive motor 120, and a driven gear 122 that meshes with the drive gear 121 is arranged near the output shaft of the second drive motor 120.

[0027] like Figure 1 As shown, connecting grooves 201 are respectively provided on the left and right sides of the top of the fixing frame 109, and a connecting slider 202 is provided at the bottom of the guide tube 110, which is slidably connected to the connecting grooves 201. The sliding hole of the connecting groove 201 and the vertical cross-section of the connecting slider 202 are both T-shaped. Through the sliding engagement of the connecting groove 201 and the connecting slider 202, the sliding connection between the guide tube 110 and the fixing frame 109 can be realized; and because the sliding hole of the connecting groove 201 and the vertical cross-section of the connecting slider 202 are both T-shaped, the vertical offset of the connecting slider 202 relative to the connecting groove 201 can be avoided.

[0028] Workers can first loosen the limiting bolt 114 to release the fixation at the connection between the horizontal cylinder 113 and the horizontal bar 112, based on the axial length of the take-up roller 100. Then, the horizontal cylinder 113, the guide cylinder 110, the guide rod 116, and the arc-shaped support block 115 can slide left and right corresponding to the telescopic push rod 111, so that the position of the arc-shaped support block 115 meets the support requirements of the take-up roller 100 with the corresponding axial length. After that, the limiting bolt 114 can be tightened again to re-fix the connection between the horizontal cylinder 113 and the horizontal bar 112. This facilitates and fully meets the needs of lifting and lowering auxiliary adjustment of the take-up roller 100 with different axial lengths.

[0029] Simply place the fixed inserts 108 at both ends of the take-up roller 100 onto the arc-shaped support block 115, and extend the output axis of the telescopic push rod 111 upward by a certain length. With the guide rod 116 sliding vertically relative to the guide insert 110, the crossbar 112, cross cylinder 113, and arc-shaped support block 115 drive the take-up roller 100 upward between the two fixed inserts 107. Then, the first drive motor 117 drives the bidirectional screw 103 to rotate through the coupling 119, causing the mounting blocks 104 and support plates 105 on both sides to move closer to each other, so that the fixed inserts 107 and fixed inserts 108 are inserted and fixed together, thereby fixing the take-up roller 100. After that, the telescopic push rod 111 can drive the arc-shaped support block 115 downward to release the support of the take-up roller 100 and apply a limiting force to the take-up roller 100. Then, the worker can easily feed the take-up roller 100.

[0030] Then the second drive motor 120 can be started. Through the cooperation of the drive gear 121 and the driven gear 122, the connecting shaft 106 is rotated. With the cooperation of another connecting shaft 106, two fixed inserts 108 and fixed inserts 107, the winding roller 100 is rotated and driven to wind up the aluminum foil.

[0031] After a period of time, once the take-up roller 100 has completed the winding process of the aluminum foil, the second drive motor 120 can be stopped. The telescopic push rod 111 drives the arc-shaped support blocks 115 on both sides to continue supporting the sides of the take-up roller 100. The first drive motor 117 separates the fixed insert block 107 from the fixed insert cylinder 108. Then, the telescopic push rod 111 can drive the arc-shaped support blocks 115 to move the take-up roller 100 downward, making it easier for workers to unload the take-up roller 100.

[0032] According to another embodiment of the present invention, such as Figure 2As shown, the top left and right sides of the base 101 are also provided with extension slide grooves 203 located on the front and rear sides of the mounting groove 102, and the front and rear ends of the support plate 105 are also provided with extension sliders 204 that are slidably connected to the extension slide grooves 203. The vertical cross section of the sliding hole of the extension slide groove 203 is T-shaped.

[0033] The extension groove 203 and the extension slider 204 work together to provide auxiliary support for the support plate 105, so that the support plate 105 can maintain stability better during sliding and stationary operation.

[0034] According to another embodiment of the present invention, such as Figure 1 As shown, scale lines 205 are also provided on both sides of the crossbar 112. The scale lines 205 allow for convenient and precise control of the adjustment position of the cross cylinder 113 relative to the crossbar 112.

[0035] According to another embodiment of the present invention, such as Figure 2 As shown, an extension plate 206 is also provided at the bottom side of the base 101, and anchor bolts 207 for connecting to the ground are also provided on the extension plate 206. Workers can pass the anchor bolts 207 through the extension plate 206 and connect them to the ground, thereby preventing the device from easily shifting or tipping over during operation.

[0036] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
