Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary products for elevator coils, in particular to an inner support folding machine for the coils, with adjustable folding depth and folding spacing. Background Art

[0002] Coils are mainly used in automotive electronics, high-frequency home appliances, wireless reception, power filtering, audio technology, intercom communications, medical electronics, new energy, elevators and other fields. When making coils for elevators, the winding wire needs to be wound on an inner support. The inner support used for winding is a kind of meta-aramid folded, which is an insulating material. The flat meta-aramid is folded into a cylindrical inner support according to folding. The required size is produced according to actual application needs. The existing folding method is manual folding, which has low folding efficiency, low accuracy and poor flexibility. Another folding method is machine folding. The folding spacing and folding depth of this folding method are not adjustable. However, the number of inner supports required for actual product applications is large and needs to be produced in batches. Therefore, there is an urgent need for a coil inner support folding machine with adjustable folding spacing and folding depth. Summary of the Invention

[0003] The purpose of the utility model is to overcome the defect of inflexible folding of coil inner supports in the above-mentioned prior art, and to provide a coil inner support folding machine with adjustable folding spacing and depth, thereby improving the quality and efficiency of folding.

[0004] The technical solution adopted by the utility model is a coil inner support folding machine, comprising a bottom bracket and an upper operating table and a collecting tray fixed on the bracket, a horizontal rotating shaft between the operating table and the collecting tray, the rotating shaft comprising two upper and lower groups engaged by gears, the rotating shaft being rotated by a transmission mechanism, a pressing knife being installed on the upper rotating shaft, the spacing and number of the pressing knives being adjustable, a flat inner support being placed on the operating table and fixed by a fixing block and then transported to the middle of the two groups of rotating shafts for folding.

[0005] Preferably, the vertical position of the rotating shaft is adjusted by an adjusting device.

[0006] Preferably, the collecting tray is arranged lower than the operating table.

[0007] Preferably, a switch is provided on the side of the bracket for controlling the start and stop of the conveying mechanism.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: the folding machine of the utility model adopts the form of upper and lower rotating shafts to adjust the folding depth, the number of folds can be flexibly adjusted by setting multiple pressing knives, the spacing of the pressing knives can adjust the spacing of the folds, and the folding is carried out through electric transmission, so the folding efficiency is high.

[0011] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0012] Aiming at the inflexible defect of the prior art folding machine, the present application provides a coil inner support folding machine, such as Figure 1 As shown, the folding machine comprises a bottom support 1, an upper operating table 2 fixed to the support 1, and a collection tray 5, the collection tray 5 being positioned below the operating table 2. A rotating shaft 3 is positioned horizontally between the operating table 2 and the collection tray 5. The rotating shaft 3 comprises two sets of meshing gears, and is rotated by a transmission mechanism 6 powered by a motor located below the operating table 2. A pressing blade 4 is mounted on the upper rotating shaft 3. The pressing blades 4 are annular and fit over the upper rotating shaft 3. The spacing and number of the pressing blades 4 are adjustable, using circular holes on the pressing blades 4 to adjust the spacing according to the actual folding needs. The flat inner support is made of an insulating material, a folded meta-aramid fiber. The flat meta-aramid fiber is placed on the operating table 2, secured by a fixing block 8, and then transported to the center of the two sets of rotating shafts 3 for folding. After folding, it falls into the collection tray 5. The rotating shaft 3 is adjusted vertically by an adjustment device 7. A switch 9 is provided on the side of the support 1 to control the start and stop of the transmission mechanism 6.

[0013] When in use, adjust the spacing of the pressing knife 4 and the upper and lower distances of the rotating shaft 3 according to the folding spacing of the inner support and the size of the folding depth, place the inner support of the plane to be folded flat on the side of the operating table 2 close to the rotating shaft, fix the position with the fixing block 8, start the switch 9, start the transmission mechanism 6 to drive the rotating shaft 3 to rotate, drive the pressing knife 4 to fold the inner support, and after folding, it falls into the collection tray 5 to continue the next round of folding operation. After the operation is completed, close the quick switch 9.
