Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment discloses a double-station non-stop reeling and unreeling machine, as shown in fig. 1-2, the machine comprises a rack 1 and a support 2, the support 2 can be relatively close to or far away from the rack 1 through the driving of a first motor 22, a rotary table 3 and a second motor are arranged on the rack 1, the second motor is connected with the center of the rotary table 3 and used for driving the rotary table 3 to rotate to realize station alternation, a rocker arm 5 is hinged on the support 2, a motor rotating shaft 6 is further arranged on the support 2 and used for rotationally driving the rocker arm 5 to swing through the motor rotating shaft 6, and the rocker arm 5 swings and contacts with a coil material to cut and receive the material.

Further, a base 21 is arranged below the support 2, the first motor 22 is located on the base 21, a sliding rail is arranged on the base 21, and the support 2 slides on the sliding rail under the action of the first motor 22.

Furthermore, there are two turntables 3, the two turntables 3 are in supporting connection through supporting rollers 32, the supporting rollers 32 are vertically positioned at two sides of the turntables 3, and the double-station winding and unwinding mechanisms 31 are horizontally positioned at two sides of the turntables 3.

Further, a press roller 51 for receiving materials is arranged on the rocker arm 5, an adhesive for adhering two rolled materials, such as a double-sided adhesive tape, is arranged at the front end of the fed rolled material, the rolled material is pressed through the press roller 51, the two rolled materials are adhered and connected, then the old rolled material is cut by a cutting assembly 52 on the rocker arm 5, the device is continuously unreeled, and the cutting assembly 53 is driven by an air cylinder 53 to swing.

The working principle is as follows: as shown in fig. 1, the right double-station unwinding mechanism 31 performs unwinding, when a coil with a large feeding diameter is needed, as shown in fig. 2, a worker drives the support 2 to move leftward on the slide rail through the first motor 22, so that the distance between the support 2 and the rack 1 is increased, then the worker puts the large-diameter coil on the left double-station unwinding mechanism 31, drives the rocker arm 5 to swing downward through the motor rotating shaft 6, so that the compression roller 51 on the rocker arm 5 extrudes the new and old coils, the adhesive on the new coil contacts and is adhesively connected with the old coil, then drives the cutting assembly 53 to swing through the cylinder 53, cuts the old coil, and then the rotary table 3 rotates counterclockwise under the action of the second motor, so as to complete feeding, receiving and cutting actions.

According to the utility model, the distance between the bracket 2 and the rack 1 is adjusted, so that the device can work on coil materials outside the working range. When the diameter of the loaded coil is larger than the maximum loading size, the bracket 2 is far away from the rack 1, so that after the coil is loaded, the rocker arm 5 cannot interfere with the large-diameter coil when the rocker arm 5 swings to perform the actions of receiving and cutting the coil; when the coil stock diameter of material loading is less than minimum material loading size, be close to frame 1 with support 2 to the coil stock is after the material loading, and rocking arm 5 swings and makes compression roller 51 can touch the minor diameter coil stock, and cutting assembly 52 cuts again, and the device can normally work.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like made within the design concept of the present invention should be included in the scope of the present invention.
