Description

Technical Field

[0001] The utility model relates to the technical field of feeding materials for a box-gluing machine, in particular to a feeding mechanism for a box-gluing machine. Background Art

[0002] In the packaging and printing industry, the application of the folder gluer is the last step in the processing of packaging boxes. It is to fold the printed and die-cut cardboard into shape and glue the edges. The machine glues the box instead of the manual box gluer, which reduces labor costs and improves efficiency. The parts of the folder gluer are divided into paper feeding part, pre-folding part, bottom hook, forming part, and box pressing part. The folder gluer is divided into smooth glue box gluer, bottom hook box gluer, etc. according to its function. The general folder gluer does not have the groove bottom function or even pre-folding. The better ones have pre-folding. Of course, most of the folder gluers now have pre-folding, so it is of course necessary to make bottom hook boxes. A groove bottom box gluer must be used. A box gluer with better functions can also make hexagonal and special-shaped boxes, but it must be equipped with a glue spraying system and other devices. In the prior art, a conveyor belt is often used to feed the box gluer. During the feeding process, the stacked cardboard is placed at the feeding position, and the friction is used to drive the conveyor belt to move the bottom cardboard in the stacked state to achieve the feeding of the box gluer. However, when too much cardboard is stacked, the bottom cardboard is subjected to greater pressure, and a greater force is required to move the cardboard, which affects the feeding accuracy of the box gluer. Utility Model Content

It uses the pressure generated by the cardboard stacking to increase the friction between the feeding component and the cardboard, making the movement of the cardboard more accurate, reducing the impact of excessive cardboard stacking on the feeding of the folder gluer, and improving the feeding efficiency of the folder gluer.

[0007] Furthermore, the feeding assembly includes a slide groove, a slider, a rotating column and a feeding roller. The slide grooves are respectively arranged in the middle of the guide inclined plate. The slide grooves gradually tilt downward from left to right. The inside of the slide grooves is slidably connected with sliders. A rotating column is rotatably connected between the two sliders. A feeding roller is provided on the outer arc surface of the rotating column. The feeding roller is installed in cooperation with the guide inclined plate to facilitate the movement of the cardboard.

[0008] Furthermore, the feeding assembly also includes a tension spring, which is respectively arranged between the slider and the left inner wall of the slide groove to increase the friction between the feeding roller and the paperboard.

[0009] Furthermore, the feeding assembly also includes guide columns, which are respectively arranged on the left side of the slider, and the guide columns respectively pass through the interior of the tension spring and the sliding hole at the left end of the sliding groove to provide guiding support for the extension and contraction of the tension spring.

[0010] Furthermore, the feeding assembly also includes a rubber pad, which is arranged on the outer arc surface of the feeding roller to increase the friction force on the surface of the feeding roller.

[0011] Furthermore, the loading assembly also includes an electric motor, which is arranged on the front surface of the slider on the front side. The output shaft of the electric motor is fixedly connected to the rotating column, and the input end of the electric motor is electrically connected to the output end of the single-chip microcomputer to provide power for the rotation of the rotating column.

[0012] Furthermore, a roller is rotatably connected in a rotating groove at the right end of the lower surface of the loading frame via a rotating shaft, thereby reducing the wear of the cardboard caused by contact with the right inner wall of the loading frame.

The lower ends of the left inner walls of the feeding frame 5 are respectively provided with guide inclined plates 6. The guide inclined plates 6 are used to guide the stacked cardboard. The cardboard at the bottom of the state is guided so that the cardboard contacts the electric conveyor belt 3. Under the action of the friction between the cardboard and the electric conveyor belt 3, the cardboard is driven to move. A single-chip microcomputer 9 is provided on the front surface of the front support plate 1 to control the start and stop of the entire device.

[0024] The feeding assembly 7 is arranged between the two guiding inclined plates 6. The feeding assembly 7 includes a slide 71, a slider 72, a rotating column 73 and a feeding roller 74.

The rotation of the feeding roller 74 is used to apply a rightward thrust to the cardboard to push the lowermost cardboard out of the feeding frame 5. The feeding roller 74 is installed in cooperation with the guiding inclined plates 6. The feeding assembly 7 also includes a tension spring 75. The tension spring 75 is respectively arranged between the slider 72 and the left inner wall of the slide 71. Under the elastic force of the tension spring 75, the feeding speed is increased.

The greater the overall gravity of the cardboard, the greater the stretching amplitude of the tension spring 75. Under the elastic force of the tension spring 75, the feeding roller 74 The greater the friction between the bottom cardboard and the bottom cardboard, the right end of the bottom cardboard is located on the lower side of the roller 8 and can move to the right. The other cardboards are blocked by the right inner wall of the loading frame 5 and will not move to the right. Then the electric motor 78 is started by the single chip microcomputer 9, and the output shaft of the electric motor 78 drives the rotating column 73 and the loading roller 74 to rotate, applying a rightward force to the bottom cardboard, so that the bottom cardboard moves to the right and contacts the surface of the electric conveyor belt 3. At the same time, the electric conveyor belt 3 is started to transport the cardboard to the right to load the folder gluer.
