Description

Technical Field

[0001] The utility model relates to the technical field of double-station rewinding machines, in particular to a rewinding positioning device for a double-station rewinding machine. Background Art

[0002] A rewinding machine is the material receiving part of a coil processing production line, which winds raw materials into coils by mechanical means and is widely used in paper coils, cloth coils, plastic coils, and metal coil processing production lines. It is designed diversely according to actual process requirements. Common ones include simple rewinding machines and hydraulic rewinding machines. Generally, there are strict requirements for the inner diameter, outer diameter, thickness, and width of the coil material. A double-station rewinding machine is a type of rewinding machine. After replacing the rewinding drum on the double-station rewinding machine, a positioning device is needed to position the newly replaced rewinding drum.

[0003] When the existing double-station rewinding machine rewinding positioning device positions the newly replaced rewinding drum, most of them use a method of fixing with multiple groups of bolts. This method has a very cumbersome positioning process, greatly reducing the working efficiency of the rewinding machine. Moreover, tools and a certain number of spare bolts need to be carried during the installation process, which is very troublesome and cannot quickly position the newly replaced rewinding drum. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that the newly replaced rewinding drum cannot be quickly positioned in the prior art, and to provide a rewinding positioning device for a double-station rewinding machine.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A rewinding positioning device for a double-station rewinding machine, including a bottom plate. Vertical plates are fixedly connected to the four circumferences of the top of the bottom plate. A bracket is slidably arranged on the right sides of the right two groups of vertical plates. A motor is embedded on one side of the bracket. The left side of the bottom of the bracket is fixedly connected with a mounting plate. Two groups of fixing nuts are symmetrically fixedly connected to the right side of each mounting plate in the front-back direction. A fixing bolt is threadedly connected in the fixing nut. The left end of the fixing bolt is fixedly connected with a plug post. A plurality of fixing jacks for cooperating with the plug post are opened on the right sides of the right two groups of vertical plates. Grooves are opened at the tops of the front and back two groups of vertical plates away from each other. A square block is clamped in the groove. A rewinding drum is rotatably installed in the left and right two groups of square blocks. The output shaft of the motor is fixedly connected with a convex block, and the left end of the convex block is clamped on the rewinding drum. An auxiliary component for cooperating with the square block is arranged on the vertical plate.

[0007] Preferably, the auxiliary component includes a pressing plate slidably arranged inside the inner cavity of the groove. Extrusion rods are fixedly connected to the peripheries of the pressing plate close to each other. One end of each extrusion rod away from the pressing plate penetrates through the vertical plate and is fixedly connected to a docking plate. Springs are wound around each group of extrusion rods, and two ends of each group of springs are fixedly connected to one side of the docking plate and the vertical plate close to each other. A strip-shaped hole is formed in the outer side of the square block. An extension plate is slidably arranged in the strip-shaped hole. A anti-detachment plate is fixedly connected to the bottom of the extension plate. A limiting groove is formed in the bottom of the inner cavity of the groove, and the bottom of the anti-detachment plate penetrates into the limiting groove. Magnetic blocks capable of mutually adsorbing are fixedly connected to the bottom of the anti-detachment plate and the bottom of the inner cavity of the limiting groove. Slide grooves are formed in both sides of the top and bottom of the inner cavity of the groove. Slide bars are slidably arranged in each group of slide grooves, and one side of each slide bar away from the slide groove is fixedly connected to the square block. Moving blocks used in cooperation with the slide grooves are fixedly connected to the top and bottom of each group of pressing plates.

[0008] Preferably, auxiliary nuts are fixedly connected to both of the right-side two vertical plates, and auxiliary bolts are threadedly connected inside the auxiliary nuts. The left end of each auxiliary bolt is fixedly connected to an auxiliary column. A round hole used in cooperation with the auxiliary column is formed in the top of the right side of the winding drum.

[0009] Preferably, a positioning column is fixedly connected to the convex block. The top end of the positioning column penetrates through the winding drum and extends upward. Slide ways are fixedly connected to the right sides of both of the right-side two vertical plates. Sliders fixedly connected to the bracket are slidably arranged inside the slide ways.

[0010] Preferably, vertical rods are fixedly connected to both sides of the top of the inner cavity of each group of strip-shaped holes. The bottom ends of the vertical rods penetrate through the extension plate and are fixedly connected to the bottom of the inner cavity of the strip-shaped hole.

[0011] Preferably, rubber pads used in cooperation with the anti-detachment plate are embedded in the bottom of the inner cavity of each group of strip-shaped holes.

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

[0013] The rewinding positioning device for the double-station rewinder facilitates the pre-installation and positioning of the winding drum by setting an auxiliary component and using the clamping connection between the sliding bar and the sliding groove to pre-clamp the square block in the groove. When the square block enters the groove, it will push the pressing plate and the extrusion rod to move synchronously and stretch the spring until the pressing plate contacts the inner side of the groove cavity. At this time, the anti-disengagement plate is clamped with the limiting groove to fix the square block again, and the elastic rebound of the spring continuously gives a reaction force to the pressing plate and the square block, making the clamping connection between the anti-disengagement plate and the limiting groove more stable and preventing disengagement. The design of the magnetic block further positions the anti-disengagement plate, thereby quickly installing and positioning the winding drum. The entire installation process of the winding drum adopts a clamping method, avoiding the need to carry tools for installation and eliminating the need to carry spare bolts, improving the installation efficiency.
