fig. 2 is a schematic side view of the paper feeding device of the present invention.
Detailed Description
The invention will be further described with reference to the following description and embodiments in conjunction with the accompanying drawings:
example 1
As shown in fig. 1-2, a paper feeding device for a paper tube machine comprises a bottom plate 1 and a backup plate 2, wherein the bottom plate 1 is horizontally placed, the backup plate 2 is vertically fixed on the bottom plate 1, a track 3 is arranged in the center of the backup plate 2, a paper hanging plate mechanism capable of sliding up and down along the track 3 is arranged on the track 3, the paper hanging plate mechanism can rotate, after the paper plate is hung on the paper hanging plate mechanism, the paper plate can rotate along with the paper hanging plate mechanism and output paper strips or paper tapes to the paper tube machine for forming the paper tube.
The paper hanging disc mechanism comprises a paper control disc 4, a fixed column 5, a nylon sleeve 6 and a bearing 7. The tension control disc 4 and the fixing column 5 are coaxially fixed together, and the diameter of the fixing column 5 is smaller than that of the tension control disc 4. After the bearing 7 passes through the axes of the tension control disc 4 and the fixed column 5, the tension control disc 4 and the fixed column 5 can be fixed on the track 3 in the center of the backup plate 2 in a vertically sliding manner, and simultaneously, the tension control disc 4 and the fixed column 5 can rotate relative to the bearing 7. The nylon sleeve 6 is fixed on the outer circumference of the fixed column 5 in a surrounding way. A plurality of elastic bulges 8 are distributed on the outer circumference of the nylon sleeve 6, when the paper plate is fixed, the hole in the center of the paper plate is sleeved on the nylon sleeve 6 outside the fixed column 5, and the elastic bulges 8 are tightly pressed on the inner wall of the hole in the center of the paper plate, so that the paper plate is firmly fixed on the fixed column 5. After the opening control disc 4 and the fixed column 5 rotate, the paper disc can be driven to rotate.
A tension control mechanism is arranged below the tension control disc 4 and used for controlling the tension required by the rotation of the paper disc. The tension control mechanism comprises two support columns 9 fixed on the bottom plate 1, the two support columns 9 are respectively located on two sides of the tension control disc 4, a tension control belt 10 is fixed between the top ends of the two support columns 9, the tension control belt 10 is made of rubber materials, and the middle of the tension control belt 10 sags downwards and is attached to the outer circumference of the tension control disc 4 in an arc shape.
The tension adjusting mechanism is arranged at the lower part of the center of the tension control belt 10 and comprises a sleeve 12 vertically fixed on the bottom plate 1, and the sleeve 12 is just positioned below the lowest point of the tension control belt 10. The sleeve 12 is provided with an elastic tightening column 13 with a spring, and the elastic tightening column 13 is contracted in the sleeve 12, elastically extends out under the action of the spring and is tightened against the center of the lower surface of the tension control band 10. Therefore, the tension control belt 10 is tightly attached to the outer circumference of the tension control disc 4, when the tension control disc 4 rotates, the friction force caused by the tension control belt 10 needs to be overcome, the tight attachment degree of the tension control belt 10 is different, and the friction force needed to be overcome when the tension control disc 4 rotates is also different.
The lower part of the sleeve 12 is further provided with an adjusting screw 14, and the adjusting screw 14 extends into the sleeve to adjust the compression amount of the spring, so that the pressure of the elastic tightening column 13 on the tension control band 10 can be adjusted.
When the device is used, an operator loads a paper disc on the nylon sleeve 6, the whole paper disc hanging mechanism slides down to the lowest point of the rail under the action of gravity of the paper disc, the elastic propping column 13 is adjusted through the adjusting screw 14, so that the elastic propping column 13 can completely attach the tension control belt 10 to the tension control disc 4, the paper disc cannot naturally rotate at the moment, the paper disc can only be driven to rotate when a paper strip or a paper tape is pulled in the operation of the machine, the pulling force is controlled by the elastic propping column, and the pulling force of the machine is equal to the sum of the resistance to be overcome when the paper disc is pulled and the friction force between the tension control disc and the tension control belt.
During the rotation of the paper disc, the diameter of the paper disc is gradually shortened along with the reduction of the paper strips, the resistance to be overcome for pulling the paper disc is gradually increased, and the paper disc is just like a lever, and the longer the fulcrum is from the end point of the lever, the more labor is saved, and the shorter the fulcrum is, the more force is applied. Meanwhile, along with the reduction of the weight of the paper disc, the spring in the elastic propping column can prop upwards at the moment, so that the contact area between the outer edge of the paper disc and the tension control band is reduced, namely the friction force of the paper disc is reduced, and the two forces are increased one by one and reduced one by one, thereby always keeping the tension on the paper strips or the paper bands consistent.
Preferably, the backup plate 2 may further be provided with a sensor for sensing whether the paper tray runs out of paper, and when the sensor senses that the paper tray runs out of paper, the sensor sends a signal to prompt the paper tray to be replaced.
The paper feeding device has the advantages of simple structure, elegant appearance, easy operation and simple and convenient learning for staff.
Those skilled in the art will recognize that a wide variety of modifications, alterations, and combinations can be made with respect to the above described embodiments without departing from the scope of the invention, and that such modifications, alterations, and combinations are to be viewed as being within the ambit of the inventive concept.
