Description

Technical Field

[0001] This utility model relates to the technical field of packaging paper production, and in particular to a paper pressing device with the function of adjusting the conveying distance of packaging paper. Background Technology

[0002] The paper pressing device is used to press and shape packaging paper. It conveys the glued packaging paper between two sets of conveyor belts. The packaging paper is pressed by the conveyor belts for a long time, so that the glue between the packaging paper is cured, which can prevent the paper from curling at the edges and make the surface of the pressed packaging paper flat.

[0003] The paper pressing device needs to leave a suitable feeding space at the paper feeding point to ensure that the spacing of the paper stacks is uniform. Since different types of paper have different sizes, when changing to other types of paper, the relative positions of the two sets of conveyor belts need to be readjusted manually, which requires a certain amount of debugging time and thus affects production efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: a paper pressing device with the function of adjusting the paper conveying distance, including a frame, and a paper feeding component and a paper pressing component disposed on the frame;

[0005] The paper feeding assembly includes a drive motor, a transmission roller, and a conveyor belt. The drive motor is connected to the transmission roller via a pulley, and the transmission roller is located at both ends of the frame. The transmission roller is wound with the conveyor belt.

[0006] The paper pressing assembly includes a moving frame, a transmission assembly, an adjusting motor, a support roller, a driven roller, a paper pressing belt, and a counterweight assembly. The adjusting motor drives the moving frame to move laterally relative to the machine frame through the transmission assembly. The moving frame is connected to a support roller for supporting the conveyor belt. Driven rollers are provided at both ends of the moving frame. The driven rollers are wound with paper pressing belts corresponding to the conveyor belt. The paper pressing belts are provided with counterweight assemblies that are distributed in a straight line.

[0007] Using the above technical solution, the drive motor controls the rotation of the conveyor belt through the transmission roller, and the conveyor belt drives the paper pressing belt to rotate. After the packaging paper is laminated and shaped, it is inserted between the conveyor belt and the paper pressing belt, completing the functions of shaping the packaging paper and curing the glue. When it is necessary to change to different types of packaging paper, the relative position between the machine frame and the moving frame is adjusted by adjusting the motor to leave a suitable paper feeding space and make the spacing of the stacked packaging paper uniform, so as to achieve fast and accurate machine adjustment and improve production efficiency.

[0008] The present invention is further configured such that the transmission assembly includes a roller shaft, a sliding bar, a rack, rollers, gears, and a timing pulley. The roller shaft is rotatably connected to the frame via ball bearings. The two ends of the movable frame are fixedly connected to the sliding bar and the rack. The roller shaft is coaxially distributed with rollers that are rolled and connected to the sliding bar, gears that mesh with the rack, and a timing pulley connected to the adjusting motor via a timing belt.

[0009] Using the above technical solution, the sliding bar and the rack are distributed in parallel on the moving frame. When the adjusting motor controls the synchronous wheel to rotate, the roller and the gear are driven to rotate simultaneously through the roller shaft, so that the moving frame moves smoothly.

[0010] The present invention is further configured such that the counterweight assembly includes a main connecting frame, a fixed rod, a secondary connecting frame, and a counterweight rod. The main connecting frame is disposed at both ends of the driven roller. The fixed rod and the secondary connecting frame are respectively connected to both sides of the main connecting frame. The secondary connecting frame is rotatably connected to a counterweight rod for pressing the paper tape.

[0011] Furthermore, the main connecting frame is connected to sub-connecting frames and counterweight rods that are arranged in a straight line, and adjacent sub-connecting frames are rotatably connected by the counterweight rods.

[0012] By adopting the above technical solution, multiple sets of counterweights are evenly distributed in a straight line on the pressure belt, thereby increasing the pressure of the pressure belt on the packaging paper. The pressure is uniform, so that the packaging paper remains in a tight state during the conveying process.

[0013] The present invention is further configured such that the fixing rod is provided with a sleeve for paper feeding positioning, a pressure bar and an adjusting rod, one end of the pressure bar is fixedly connected to the sleeve, and the other end abuts against the conveyor belt, and the sleeve is threadedly connected with an adjusting rod for locking the rotation angle of the pressure bar.

[0014] With the above technical solution, the pressure strip is set in the direction of paper feeding. Through the positioning of the pressure strips on both sides, the paper feeding direction is always in the direction of the conveyor belt movement, so as to avoid problems such as rotational misalignment, curling and bending when the paper contacts the conveyor belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When it is necessary to change to different types of packaging paper, the relative position between the motor control frame and the moving frame is adjusted to leave a suitable paper feeding space and make the spacing of the stacked packaging paper uniform, thereby realizing automatic machine adjustment and improving production efficiency.

The paper pressing assembly 3 includes a moving frame 31, a transmission assembly 32, an adjusting motor 33, a support roller 34, a driven roller 35, a paper pressing belt 36, and a counterweight assembly 37. The adjusting motor 33 drives the moving frame 31 to move laterally relative to the frame 1 via the transmission assembly 32. The moving frame 31 is connected to a support roller 34 for supporting the conveyor belt 23. Driven rollers 35 are located at both ends of the moving frame 31. The driven rollers 35 are wound with paper pressing belts 36 corresponding to the conveyor belt 23. The paper pressing belt 36 is provided with counterweight assemblies 37 arranged in a straight line.

[0026] Combination Figure 3 , 4As shown, in this embodiment, the transmission assembly 32 includes a roller shaft 321, a sliding bar 322, a rack 323, a roller 324, a gear 325, and a synchronous pulley 326. The roller shaft 321 is rotatably connected to the frame 1 via ball bearings. The sliding bar 322 and the rack 323 are fixedly connected to both ends of the movable frame 31. The roller shaft 321 is coaxially distributed with the roller 324 rollingly connected to the sliding bar 322, the gear 325 meshing with the rack 323, and the synchronous pulley 326 connected to the adjusting motor 33 via a synchronous belt. The sliding bar 322 and the rack 323 are distributed parallel to each other on the movable frame 31. When the adjusting motor 33 controls the synchronous pulley 326 to rotate, the roller shaft 321 simultaneously drives the roller 324 and the gear 325 to rotate, making the movable frame 31 move smoothly.

[0027] Combination Figure 5 , 6 As shown, in this embodiment, the counterweight assembly 37 includes a main connecting frame 371, a fixed rod 372, a secondary connecting frame 373, and a counterweight rod 374. The main connecting frame 371 is located at both ends of the driven roller 35. The fixed rod 372 and the secondary connecting frame 373 are respectively connected to both sides of the main connecting frame 371. The secondary connecting frame 373 is rotatably connected to the counterweight rod 374 for pressing the paper tape 36. The main connecting frame 371 is connected to the secondary connecting frames 373 and the counterweight rod 374, which are arranged in a straight line.

Through the positioning of the pressure strips 376 on both sides, the paper feeding direction of the packaging paper is always in the direction of movement of the conveyor belt 23, so as to avoid problems such as rotational misalignment, curling edges, and bending when the packaging paper contacts the conveyor belt 23.

[0029] The working principle of this utility model is as follows: the drive motor 21 controls the rotation of the transmission roller 22 through the synchronous belt, and the transmission roller 22 drives the conveyor belt 23 to move. The conveyor belt 23 drives the pressure belt 36 to rotate and causes the driven wheel to rotate. When the packaging paper is laminated and formed, it is inserted into the space between the conveyor belt 23 and the pressure belt 36 from the paper inlet. The conveyor belt 23 transports the packaging paper. The pressure belt 36 is equipped with multiple sets of counterweights 374 to apply pressure to the packaging paper, so that the packaging paper is transported to the paper outlet. During this period, the glue in the packaging paper is cured until it is shaped. When the required packaging paper type is needed, the central control system selects the type of packaging paper. The relative position between the control frame 1 and the moving frame 31 is quickly adjusted by adjusting the motor 33, so as to leave a suitable paper feeding space and make the spacing of the stacked packaging paper uniform, thereby improving the overall quality of the packaging paper after lamination.
