Description

Technical Field

[0001] The utility model relates to an unwinding machine. Background Art

[0002] During the production of the microchannel heat exchanger tube making machine and fin machine, in order to facilitate the transportation of the coiled material, the coiled material must be placed on the uncoiler. The uncoiler supports the coiled material and rotates the coil to release the material, which is convenient for subsequent transportation.

[0003] The current uncoiler, due to structural limitations, has a very large inner diameter of the coil, which affects the amount of coiled material, so the frequency of material changes increases. Moreover, since it can only install one coil, it cannot meet the feeding needs of a multi-channel tube making machine. In order to improve the production efficiency of the tube making machine or the fin machine, multiple channels are generally set up for feeding, and multiple tubes or fins are produced at the same time. This requires an uncoiler that can install multiple coils. Summary of the invention

[0007] Preferably, the first wedge block has a first screw mounting hole, the first screw mounting hole passes through the axial surface of the first wedge block, and the first notch of the support sleeve has a corresponding first screw hole, the second wedge block has a second screw mounting hole, the second screw mounting hole passes through the radial surface of the second wedge surface, and the second notch of the support sleeve has a corresponding second screw hole; when installing the material roll, the screw passes through the second mounting hole on the second wedge block and is tightened on the outer ring radial surface of the second notch of the support sleeve. After tightening, the second wedge block is fixed to the support sleeve. After the material roll is installed on the support sleeve, the screw is passed through the first mounting hole and screwed on the outer ring axial side surface of the first notch of the support sleeve, and then the screw is gradually tightened until the two wedge surfaces of the oppositely arranged first wedge surface and the second wedge surface clamp the material roll.

[0008] Specifically, the support shaft is fixedly supported and axially limited by a first flange and a second flange on two sides of the support seat and a flange end cover installed on the first flange.

[0009] Specifically, each support locking assembly is rotatably supported by two sets of bearings installed on the support shaft. Spacers are provided at both ends of the bearings. The spacers are installed on the support shaft. The spacers are limited by the end covers at both ends of the support shaft, so that each support locking assembly can be axially positioned.

[0010] Preferably, a first boss edge is also provided on the first wedge block, and a second boss edge is also provided on the second wedge block, and the material roll is placed between the first boss edge and the second boss edge, so that the material roll can be better limited.

[0011] Preferably, there are multiple support locking assemblies which are installed side by side on the support shaft, and a spacer is provided between the two support locking assemblies. The spacer is limited by the end covers at both ends of the support shaft. This is for axial positioning on the one hand, and the distance between the two support locking assemblies can be adjusted by adjusting the length of the spacer on the other hand.

[0012] Compared with the prior art, the advantages of the utility model are: the first wedge block and the second wedge block are used to support and lock the material roll, and corresponding notches are provided on the support sleeve to accommodate the wedge blocks, so that the inner hole of the material roll becomes smaller, the amount of material is increased, and the frequency of material change is reduced, thereby reducing the waste of material change time.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a uncoiler includes a support seat 1, a support shaft 2 and a support locking assembly.

[0022] One end of the support shaft 2 passes through the support seat 1 and is fixedly supported by the support seat 1, specifically, the support shaft 2 is fixedly supported and axially limited by a first flange 101 on the left side of the support seat 1, a second flange 102 on the right side of the support seat 1, and a flange end cover 103 installed on the first flange 101.

[0023] The support locking assembly is installed on the support shaft 2 and is rotatably supported by the support shaft 2. Specifically, each support locking assembly is rotatably supported by two sets of bearings 201 installed on the support shaft 2. Both ends of each set of bearings 201 are provided with spacers 202. The spacers 202 are installed on the support shaft 2. An end cover 203 is also installed at the end of the support shaft 2. The end cover 203 supports the spacer 202 at the end of the support shaft 2 and is locked on the support shaft 2 by screws 5. In this way, the support locking assembly can be axially positioned.

[0024] There can be multiple support locking assemblies installed side by side on the support shaft 2, and a spacer 202 is added between the two support locking assemblies accordingly. The spacer is limited by the end covers 203 and 102 at the two ends of the support shaft. This is for axial positioning on the one hand, and on the other hand, the distance between the two support locking assemblies can be adjusted by adjusting the length of the spacer 202.

[0025] Specifically, the support locking assembly includes a support sleeve 301, a first wedge block 302 and a second wedge block 303. Both ends of the support sleeve 301 are respectively arranged along the circumference with a plurality of first notches 3011 and a plurality of second notches 3012. The first wedge blocks 302 are installed in the first notches 3011 of the support sleeve 2, and the number of the first notches 3011 on the support sleeve 2 is the same as the number of the first notches 3011 on the support sleeve 2. The second wedge blocks 303 are installed in the second notches 3012 of the support sleeve 2, and the number of the second notches 3012 on the support sleeve 2 is the same as the number of the second notches 3012 on the support sleeve 2.

[0026] The first wedge block 302 has a first wedge surface 3021 , and the second wedge block 303 has a second wedge surface 3031 . When the material roll is placed outside the support sleeve 301 , its two ends can be fixed by the first wedge surface 3021 and the second wedge surface 3031 , respectively.

[0027] The first wedge block 302 has a first screw mounting hole 3023, which passes through the axial surface of the first wedge block 302, and the first notch 3011 of the support sleeve 301 has a corresponding first screw hole 3013, the second wedge block 303 has a second screw mounting hole 3033, which passes through the radial surface of the second wedge surface 3031, and the second notch 3012 of the support sleeve 2 has a corresponding second screw hole (not shown in the figure).

[0028] When a new material roll is to be replaced, the screw 4 is passed through the second mounting hole 3033 on the second wedge block 303 and tightened on the outer ring radial surface of the second notch 3012 of the support sleeve 301. After tightening, the second wedge block 303 is fixed to the support sleeve 302. After the new material roll is installed on the support sleeve 302, the screw 4 is passed through the first mounting hole 3023 and screwed on the outer ring axial side surface of the first notch 3011 of the support sleeve 301, and then the screw is gradually tightened until the two wedge surfaces of the oppositely arranged first wedge surface 3021 and the second wedge surface 3031 clamp the material roll. In this way, the material roll is replaced, and the material roll can rotate around the support shaft 2 to feed the material. Moreover, it is very convenient to replace and install the material roll.

[0029] A first boss edge 3022 is further provided on the first wedge block 302, and a second boss edge 3032 is further provided on the second wedge block 303. The material roll is placed between the first boss edge 3022 and the second boss edge 3032, so that the material roll can be better limited.
