[0002] The wire reel locking device on the cigarette box or cigarette rod transparent paper packaging machine is generally a manually rotated locking cone sleeve with an internal thread. The threaded transmission is used to make the cone sleeve squeeze the contact surfaces at both ends of the inner core of the wire reel, and rely on its own deformation tension to achieve axial positioning and radial tensioning of the wire reel, thereby locking the wire reel between the two cone sleeves.

[0003] The wire reel tensioning device is also a device used in the production process of tobacco products. Its main function is to make the replacement of the wire reel more efficient and portable, thereby reducing labor intensity and improving production efficiency.

[0004] When the wire material of the GD machine is exhausted, the wire reel needs to be replaced. The wire reel tensioning device in the prior art includes a wire reel support and a clamping cover plate, wherein one end of the wire reel is mounted on the support, and the other end is clamped by hand through the central thread of the clamping cover plate.

[0005] During the actual use of the equipment, the clamping cover needs to be completely cranked down by hand and then cranked up by hand during installation. Due to the long length of the thread, the whole process takes about 5 minutes. During the operation of the equipment, the clamping cover will also become loose due to frequent and prolonged vibration, which will cause the wire reel to fall off, causing the wire to be misplaced and broken, affecting the quality of cigarette packs and equipment efficiency, greatly increasing the defective rate of cigarette packs, and increasing production costs to a certain extent. Utility Model Content

[0006] The utility model aims to solve the technical problems in the prior art that the operation is time-consuming and labor-intensive and the pressing cover plate is easy to become loose, and provides a wire pulling drum tensioning device.

[0009] When the old cable drum needs to be disassembled, the supporting tensioning mechanism can be loosened by rotating the nut a little bit, and the old cable drum can be removed. When installing the new cable drum, the drum is first put on, and the nut is rotated a little bit to fix the cable drum. The utility model solves the technical problems of time-consuming and labor-intensive installation and removal of the cable drum and the loosening of the pressing cover plate in the prior art.

[0010] Further preferably, each hinge seat on the circular ring member is composed of two ear plates, and the end of the bracket rod extends into and is connected between the two ear plates, so that the connection structure is stable.

[0011] Further preferably, the four hinge seats are evenly arranged on the outer circle of the circular ring.

[0012] Further preferably, the connecting rod and the support rod, and the support rod and the circular ring are connected by rivets. The rivet connection method has a simple structure and is reliable.

[0013] Further preferably, the circular ring member on one side close to the wire pulling drum support is connected to the core shaft via a stop screw.

[0014] Further preferably, the nut is a handle nut. The tensioning device can be tightened or loosened by rotating the handle nut, which is easy to operate and labor-saving.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] When the old cable drum needs to be disassembled, the supporting tensioning mechanism can be loosened by rotating the nut a little bit, and the old cable drum can be removed. When installing the new cable drum, the drum is first put on, and the nut is rotated a little bit to fix the cable drum. The utility model solves the technical problems of time-consuming and labor-intensive installation and removal of the cable drum and the loosening of the pressing cover plate in the prior art.

[0023] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 A wire pulling drum tensioning device shown in the figure comprises a disc-shaped wire pulling drum support 1, a core shaft 7 is fixedly provided at the center of the wire pulling drum support 1, two circular ring members 2 are sleeved on the core shaft 7, four hinged seats are provided on the circular ring members 2, a support rod 3 is hinged on each hinged seat on the two circular ring members 2, the support rods 3 on the two circular ring members 2 are connected by a connecting rod 4, the end of the core shaft 7 has an external thread, and a nut 6 is installed on the external thread of the core shaft 7.

[0025] When the old cable drum needs to be disassembled, the supporting tensioning mechanism can be loosened by rotating the nut a little bit, and the old cable drum can be removed. When installing the new cable drum, the drum is first put on, and the nut is rotated a little bit to fix the cable drum. The utility model solves the technical problems of time-consuming and labor-intensive installation and removal of the cable drum and the loosening of the pressing cover plate in the prior art.

[0026] Among them, four hinged seats are evenly arranged on the outer circle of the circular ring member 2, and each hinged seat on the circular ring member 2 is composed of two ear plates. The end of the bracket rod 3 extends between the two ear plates for connection, and the connection structure is stable.

[0027] The connecting rod 4 and the support rod 3 as well as the support rod 3 and the circular ring member 2 are connected via rivets 5. The connection method of rivets 5 is simple in structure and reliable.
