Description

Technical Field

[0001] The utility model relates to the technical field of carton production, and specifically, to a slitting device for corrugated carton production. Background Art

[0002] Corrugated cartons are a relatively widely used packaging product. Corrugated cartons have excellent performance and belong to green environmental protection products. They are environmentally friendly and conducive to loading, unloading and transportation. In the process of making corrugated cartons, processes such as slitting, die-cutting, indentation, and box gluing of corrugated cardboard are required. When slitting corrugated cardboard, since some corrugated paper is large in size, a slitting device needs to be used for auxiliary slitting. There are many existing technologies for slitting devices for corrugated paper:

[0003] For example, a slitting device for corrugated carton production with the Chinese patent publication number: CN213647759U, including a slitting machine body. A dust collection box and a blower are provided on the top of the slitting machine body. The dust collection box is connected to the blower. A spring pipeline is connected to one side of the blower. The end of the spring pipeline away from the blower is connected to a connecting pipeline. Branch pipes are respectively connected to both sides of the connecting pipeline. The other end of the branch pipe is connected to a dust suction hood. Baffle plates are symmetrically provided on the slitting machine body. One end of the baffle plate is movably connected to the slitting machine body through a hinge. Connecting blocks are fixedly provided at the bottoms of the baffle plates. A support frame is movably connected to the connecting blocks. The end of the support frame away from the connecting block is movably connected to a movable block. A control box is installed on one side of the slitting machine body;

[0004] Currently, when slitting corrugated cardboard using a slitting device, the corrugated cardboard needs to be placed inside the slitting machine body. The dust generated during the slitting process will be absorbed through the blower and the branch pipes. The cutting waste chips are placed on the baffle plates for unified collection. When the corrugated paper is taken out of the slitting machine after slitting, it is easy to drive the waste chips accumulated on the baffle plates to slide out, which to a certain extent affects the waste chip collection of the corrugated paper and also affects the cutting environment of the corrugated paper, thereby reducing the slitting quality of the corrugated paper. In view of this, we propose a slitting device for corrugated carton production. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the above-mentioned drawbacks and provide a slitting device for corrugated carton production that drives waste chip collection and the discharge of corrugated cardboard by flipping the bottom plate.

[0006] By flipping the bottom plate, the waste chips generated during the slitting process can be collected, and at the same time, it can also assist in pushing the corrugated cardboard after slitting, causing the corrugated cardboard to be swept out for discharge.

[0007] Therefore, the present utility model provides a slitting device for corrugated cardboard box production, which includes a device housing body. A slitting chamber is provided inside the device housing body. A cover door is movably installed on one side of the slitting chamber.

Dust removal components are connected to both sides of the slitting knife body, and the other ends of the dust removal components are installed on the outer wall of the device housing body;

[0008] A bottom box body is fixedly installed at the bottom of the inner cavity of the slitting chamber. A bottom plate is rotatably provided at the upper end of the inner cavity of the bottom box body. A flipping component for flipping and discharging the waste chips cut out is installed at the end of the bottom plate.

[0009] As a further improvement of this technical solution, the flipping component includes an outer support plate fixedly connected to the outer wall of one side of the device housing body.

The other sides of the multiple rotating shafts away from the sub-plates are connected to activation parts, and the activation parts are installed inside the outer support plate.

[0010] As a further improvement of this technical solution, the dust removal component includes a dust suction branch pipe installed on the side wall of the slitting knife body. The dust suction branch pipe is of a telescopic structure. The other end of the dust suction branch pipe extends out of the outer wall of the device housing body and is connected to a dust removal bag. A blower body is sleeved and installed outside the dust removal bag. A dust scraping plate for scraping and discharging the corrugated cardboard after slitting is installed on the side of the slitting chamber away from the cover door.

[0011] As a further improvement, two linkage plates are fixedly connected to the surface of the sub-plate close to the cover door side, and the two linkage plates are respectively installed at the upper and lower ends of the sub-plate.

[0012] As a further improvement, a plurality of support grooves are provided on both sides of the inner wall of the bottom box body.

[0028] When taking out the corrugated paper from the inside of the slitter after the corrugated paper is slit, it is easy to drive the waste scraps accumulated on the baffle plate to slide out, which to a certain extent affects the collection of waste scraps of corrugated paper and also affects the cutting environment of the corrugated paper, thereby reducing the slitting quality of the corrugated paper.

[0029] Please refer to Figures 1-5 As shown, the device includes a device housing body 1. A slitting chamber 12 is provided inside the device housing body 1. A cover door 11 is movably installed on one side of the slitting chamber 12. A cylinder 15 is fixedly installed at the top of the inner cavity of the slitting chamber 12. A tool starting plate 16 is installed at the end of the piston rod of the cylinder 15. A slitting knife body 17 for slitting corrugated cardboard is slidably provided on the surface of the tool starting plate 16. Dust removal components 3 are connected to both sides of the slitting knife body 17, and the other ends of the dust removal components 3 are installed on the outer wall of the device housing body 1. A bottom box body 13 is fixedly installed at the bottom of the inner cavity of the slitting chamber 12. A bottom plate 14 is rotatably provided at the upper end of the inner cavity of the bottom box body 13. A turning component 2 for turning and discharging the cut waste chips is installed at the end of the bottom plate 14.

[0030] Among them, the cylinder 15 is used to drive the tool starting plate 16 to move vertically inside the slitting chamber 12. The cylinder 15 is based on pneumatic transmission, which is prior art and will not be elaborated here.

[0031] What needs to be disclosed is that in the tool starting plate 16, the movement of the slitting knife body 17 can be precisely controlled by a computer numerical control system (CNC). The CNC system can adjust parameters such as the motor speed, feed speed, and cutting force to optimize the processing efficiency and quality. At the same time, the CNC system can also monitor and detect the processing process in real time. Here, prior art is adopted and will not be elaborated here.

[0032] First, the specific structure of the turning component 2 is disclosed. The turning component 2 includes an outer support plate 21 fixedly connected to the outer wall of one side of the device housing body 1. The bottom plate 14 is composed of multiple sub - plates 141. A rotating shaft 23 is fixedly connected to the side of each of the multiple sub - plates 141 close to the outer support plate 21. The other sides of the multiple rotating shafts 23 are connected to a starting member 22, and the starting member 22 is installed inside the outer support plate 21. When the corrugated cardboard laid on the surface of the bottom plate 14 needs to be slit, through the starting member 22, the multiple sub - plates 141 are driven to turn away from the cover door 11 at the same time. During the turning process, the corrugated cardboard on the surface of the bottom plate 14 can be driven to slide to the other side of the slitting chamber 12, facilitating the discharging of the corrugated cardboard. At the same time, through the turning operation of the multiple sub - plates 141, the slitting waste chips remaining on the surface of the bottom plate 14 can be turned into the bottom box body 13. When there is too much waste in the bottom box body 13, the waste is uniformly discharged by opening the discharge port (not shown in the figure) at the bottom end of the bottom box body 13;

[0033] Among them, the specific structure of the starting member 22 is formed by the meshing connection of multiple gears and chains. The rotation of the gears can be driven by a motor, and the single - rotation angle of the motor is set to 180 degrees, making the surface of the bottom plate 14 flat, facilitating the support and slitting of the corrugated cardboard.

[0034] Next, the specific structure of the dust removal component 3 is disclosed. The dust removal component 3 includes a dust suction branch pipe 31 installed on the side wall of the slitting knife body 17. The dust suction branch pipe 31 is a telescopic structure. The other end of the dust suction branch pipe 31 extends out of the outer wall of the device housing body 1 and is connected to the dust removal bag 32. A fan body 33 is sleeved and installed outside the dust removal bag 32. A dust scraping plate 34 for scraping and sweeping the corrugated cardboard after slitting is installed on one side of the slitting chamber 12 away from the cover door 11. It can be seen that when the slitting knife body 17 is started, the fan body 33 needs to be turned on at the same time. The fan body 33 starts to draw air, so that the flying chips generated during the operation of the slitting knife body 17 can be sucked into the interior of the dust removal bag 32 through the dust suction branch pipe 31. The dust removal bag 32 is used to collect the flying chips, reducing the amount of flying dust in the slitting chamber 12 and the influence of the amount of flying dust on the cutting of the corrugated cardboard. Among them, a discharge port (not shown in the figure) is opened at the bottom end of the dust removal bag 32, which is convenient for pouring out the waste chips inside the dust removal bag 32. When the corrugated cardboard after slitting slides to the side of the slitting chamber 12 away from the cover door 11 driven by the flipping of the bottom plate 14, it can pass through the middle of the dust scraping plate 34, achieving the effect of scraping and cleaning the surface of the corrugated cardboard. The dust scraping plate 34 is formed by splicing two upper and lower elastic scraping plates.

[0035] When the corrugated cardboard is placed on the surface of the bottom plate 14 for slitting, it is inconvenient to position the placement position of the corrugated cardboard, which easily affects the recognition of the corrugated cardboard by the slitting knife body 17. Therefore, in order to more conveniently position the corrugated cardboard, two linkage plates 4 are fixedly connected to the surface of the partition plate 141 on the side close to the cover door 11, and the two linkage plates 4 are respectively installed at the upper and lower ends of the partition plate 141. When the corrugated cardboard is placed inside the slitting chamber 12, the end of the corrugated cardboard is attached to the end of the linkage plate 4 on the surface of the side partition plate 141, achieving the effect of positioning the corrugated cardboard, which is more convenient for the slitting knife body 17 to identify and slit the corrugated cardboard. When multiple partition plates 141 are flipped at the same time, the linkage plates 4 can also push the corrugated cardboard, making it more convenient for the corrugated cardboard to slide to the other side of the slitting chamber 12, improving the discharging effect of the corrugated cardboard. The two linkage plates 4 are respectively placed at the upper and lower ends of the partition plate 141, so that after each flipping of the partition plate 141, a linkage plate 4 is provided on the surface of the side close to the cover door 11.

[0036] Considering that the bottom plate 14 needs to support the corrugated cardboard, therefore, in order to further improve the support of the bottom plate 14, a plurality of support grooves 5 are opened on both sides of the inner wall of the bottom box body 13. A shaft body 51 is rotatably provided inside the upper end of each of the plurality of support grooves 5, and an auxiliary support plate 52 for supporting the bottom of the bottom plate 14 is fixedly installed on the surface of each of the plurality of shaft bodies 51.

[0037] The improvement lies in that: the auxiliary support plate 52 is installed on the side wall of the bottom box body 13 through the shaft body 51. In the static state, the auxiliary support plate 52 is in a state parallel to the bottom of the inner cavity of the bottom box body 13, and the top of the auxiliary support plate 52 fits against the bottom of the bottom plate 14, achieving the effect of auxiliary support for the bottom plate 14. When the bottom plate 14 is turned over, it can press the auxiliary support plate 52 to drive the shaft body 51 to rotate. Among them, the shaft body 51 is a one-way rotating automatic reset shaft. As the bottom plate 14 rotates, the auxiliary support plate 52 will be squeezed into the inside of the support groove 5. When the bottom plate 14 turns over and slides over the surface of the auxiliary support plate 52, the shaft body 51 loses the pressing force and rebounds, driving the auxiliary support plate 52 to return to the state parallel to the bottom of the inner cavity of the bottom box body 13 again, and assisting in supporting the bottom plate 14 again.

[0038] To sum up, the working principle of this solution is as follows: when the corrugated cardboard needs to be cut, first take out the cover door 11, then place the corrugated cardboard to be cut flat on the surface of the bottom plate 14, and the end of the corrugated cardboard needs to fit against the side wall of the linkage plate 4. Close the cover door 11. When the cutting knife body 17 is started, the fan body 33 needs to be started at the same time. The fan body 33 starts to draw air, so that the flying chips generated during the operation of the cutting knife body 17 can be sucked into the inside of the dust removal bag 32 through the dust suction branch pipe 31, and the dust removal bag 32 is used to collect the flying chips, reducing the amount of flying dust in the cutting chamber 12 and reducing the impact of the amount of flying dust on the cutting of the corrugated cardboard;

[0039] When the corrugated cardboard laid flat on the surface of the bottom plate 14 needs to be cut, through the starting member 22, drive a plurality of dividing plates 141 to turn away from the cover door 11 at the same time. During the turning process, it can drive the corrugated cardboard on the surface of the bottom plate 14 to slide to the other side of the cutting chamber 12, facilitating the discharging of the corrugated cardboard. At the same time, through the turning operation of the plurality of dividing plates 141, the cutting waste chips remaining on the surface of the bottom plate 14 can be turned over into the inside of the bottom box body 13 for collection.
