Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, and in particular to a cross-cutting machine for cardboard processing. Background Technology

[0002] Cardboard is typically produced by gluing thin layers of paper together to create thicker and stronger cardboard. In the cardboard processing industry, cardboard needs to be cut using a cross-cutting machine to produce large packaging boxes of different sizes. However, when existing cross-cutting machines are in operation, the cutting blades are prone to attracting glue from inside the cardboard due to frictional heat. During the cutting process, the glue on the blade surface absorbs a large amount of dust, paper scraps, and other impurities, causing the blade's local mass to increase and its center of gravity to shift. The blade vibrates significantly during high-speed operation due to this shift in the center of gravity, affecting the cutting quality of the cardboard. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the prior art where the glue on the blade surface absorbs a large amount of dust, paper scraps and other impurities during the cutting process, resulting in an increase in the local mass of the blade and a shift in the center of gravity. Therefore, this invention proposes a cross-cutting machine for cardboard processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a cardboard cross-cutting machine, including a column, a conveyor roller assembly installed at the bottom of the column for transporting cardboard, a sliding rail horizontally fixed to the top of the column, multiple sliding seats slidably fitted on the sliding rail, a baffle fixed to the bottom of the sliding seat, a motor fixed to the bottom of the baffle, a cutting blade fixed to the output shaft of the motor, spline shafts rotatably mounted on both sides of the top of the baffle, two stops fixedly spaced on the spline shaft, two cleaning wheels slidably fitted on the spline shaft between the two stops, and springs sleeved on the spline shaft to apply pressure to the cleaning wheels so that the cleaning wheels abut against the cutting blade.

[0006] Preferably, the spring is always in a compressed state.

[0007] Preferably, the baffle is provided with a rotating structure to drive the spline shaft to rotate.

[0008] Preferably, the rotating structure includes a driving pulley, a belt, and a driven pulley. The driving pulley is fixedly connected to the output shaft of the motor, the driven pulley is fixedly connected to the splined shaft, and the belt is fitted onto both the driving pulley and the driven pulley.

[0009] Preferably, the sliding seat is provided with a travel trolley for driving the sliding seat to move on the sliding track.

[0010] Preferably, a negative pressure chamber is provided in the middle of the sliding seat, a feed pipe is provided at the bottom of the negative pressure chamber, and an air extraction pipe is connected to the top of the negative pressure chamber.

[0011] Preferably, the negative pressure chamber is a square shell with a thin wall structure.

[0012] Preferably, the air extraction pipe is connected to an air extraction pump.

[0013] The present invention discloses a cardboard cross-cutting machine, which has the following advantages: During operation, the cardboard cross-cutting machine uses two cleaning wheels to elastically clamp the cutting blade and polish and clean the surface of the cutting blade, thereby preventing impurities from accumulating on the cutting blade for a long time and causing vibration due to changes in the center of gravity during cutting.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1 and Figure 2 A cardboard cross-cutting machine includes a column 1, a conveyor roller group 2 installed at the bottom of the column 1 for transporting cardboard, a sliding rail 3 horizontally fixed to the top of the column 1, a plurality of sliding seats 4 slidably fitted on the sliding rail 3, a travel trolley 5 provided on the sliding seat 4 for driving the sliding seat 4 to move on the sliding rail 3, a baffle 6 fixed to the bottom of the sliding seat 4, a motor 7 fixed to the bottom of the baffle 6, a cutting blade 8 fixed to the output shaft of the motor 7, a spline shaft 12 rotatably mounted on both sides of the top of the baffle 6, two stops 13 fixedly fixed at intervals on the spline shaft 12, two cleaning wheels 15 slidably fitted on the spline shaft 12 between the two stops 13, and a spring 14 sleeved on the spline shaft 12 to apply pressure to the cleaning wheels 15. The spring 14 is always in a compressed state so that the cleaning wheels 15 abut against the cutting blade 8.

[0022] When the device is working, the cardboard is transported to the cutting blade 8 by the conveyor roller group 2. When the cardboard is about to reach the cutting station, the motor 7 is powered on and started. After the motor 7 starts, it will drive the cutting blade 8 to rotate, thereby cutting the cardboard transported on the conveyor roller group 2 to achieve the purpose of cross-cutting the cardboard.

[0023] like Figures 3-5 As shown, the baffle 6 is provided with a rotating structure to drive the spline shaft 12 to rotate. The rotating structure includes a driving pulley 9, a belt 10 and a driven pulley 11. The driving pulley 9 is fixed to the output shaft of the motor 7, the driven pulley 11 is fixed to the spline shaft 12, and the belt 10 is fitted on both the driving pulley 9 and the driven pulley 11.

[0024] When the motor 7 starts, it also drives the drive pulley 11 to rotate. During the rotation of the drive pulley 11, it drives the belt 10 to run. During the operation of the belt 10, the power is transmitted to the driven pulley 11, so that the driven pulley 11 rotates. The driven pulley 11 is fixed on the spline shaft 12. During the rotation of the driven pulley 11, it drives the spline shaft 12 to rotate synchronously. The rotation of the spline shaft 12 drives the two cleaning wheels 15 on the shaft to rotate. Since the two cleaning wheels 15 are tightly pressed against the surface of the cutting blade 8 under the elastic force of the spring 14 in the compressed state, the two cleaning wheels 15 will polish and clean the dust, paper scraps, glue and other impurities attached to the surface of the cutting blade 8 during the rotation of the two cleaning wheels 15, thereby ensuring the cleanliness of the surface of the cutting blade 8 and preventing the center of gravity of the cutting blade 8 from shifting due to the attachment of impurities.

[0025] like Figure 4 and Figure 5 As shown, a negative pressure chamber 16 is provided in the middle of the sliding seat 4. A feed pipe 18 is provided at the bottom of the negative pressure chamber 16. An air extraction pipe 17 is connected to the top of the negative pressure chamber 16. The negative pressure chamber 16 is specifically a square shell with a thin wall structure. The air extraction pipe 17 is connected to an air extraction pump.

[0026] The air pump draws air from the negative pressure chamber 16 through the air extraction pipe 17. After the air is drawn from the negative pressure chamber 16, the interior of the negative pressure chamber 16 is always under negative pressure. The feed pipe 18 at the bottom of the negative pressure chamber 16 simultaneously extracts the impurities that are ground off the surface of the cleaning wheel 15, so as to clean the impurities attached to the surface of the cleaning wheel 15 and prevent the impurities on the cleaning wheel 15 from causing secondary contamination to the cutting blade 8.

[0027] Working principle:

[0028] When the device is working, the cardboard is transported to the cutting blade 8 by the conveyor roller group 2. When the cardboard is about to reach the cutting station, the motor 7 is powered on and started. After the motor 7 starts, it will drive the cutting blade 8 to rotate, thereby cutting the cardboard transported on the conveyor roller group 2 to achieve the purpose of cross-cutting the cardboard.

[0029] When the motor 7 starts, it also drives the drive pulley 11 to rotate. During the rotation of the drive pulley 11, it drives the belt 10 to run. During the operation of the belt 10, the power is transmitted to the driven pulley 11, so that the driven pulley 11 rotates. The driven pulley 11 is fixed on the spline shaft 12. During the rotation of the driven pulley 11, it drives the spline shaft 12 to rotate synchronously. The rotation of the spline shaft 12 drives the two cleaning wheels 15 on the shaft to rotate. Since the two cleaning wheels 15 are tightly pressed against the surface of the cutting blade 8 under the elastic force of the spring 14 in the compressed state, the two cleaning wheels 15 will polish and clean the dust, paper scraps, glue and other impurities attached to the surface of the cutting blade 8 during the rotation of the two cleaning wheels 15, thereby ensuring the cleanliness of the surface of the cutting blade 8 and preventing the center of gravity of the cutting blade 8 from shifting due to the attachment of impurities.

[0030] The air pump draws air from the negative pressure chamber 16 through the air extraction pipe 17. After the air is drawn from the negative pressure chamber 16, the interior of the negative pressure chamber 16 is always under negative pressure. The feed pipe 18 at the bottom of the negative pressure chamber 16 simultaneously extracts the impurities that are ground off the surface of the cleaning wheel 15, so as to clean the impurities attached to the surface of the cleaning wheel 15 and prevent the impurities on the cleaning wheel 15 from causing secondary contamination to the cutting blade 8.

[0031] Compared with the prior art, the cardboard processing cross-cutting machine of this utility model application uses two cleaning wheels 15 to elastically clamp the cutting blade 8 during operation to polish and clean the surface of the cutting blade 8, thereby preventing impurities from accumulating on the cutting blade 8 for a long time and causing vibration of the cutting blade 8 due to changes in the center of gravity during operation.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
