Description

Technical Field

[0001] The utility model relates to the field of packaging paper tube manufacturing, and more specifically, to a packaging paper tube slitting device. Background Art

[0002] Hollow packaging paper tube is a commonly used packaging material, mainly made of paper or cardboard. Its structure is a hollow cylinder, and both ends are usually open, which is convenient for putting in or taking out the packaged items. The diameter, length and thickness of the packaging paper tube can be customized according to specific needs to meet different packaging requirements.

[0003] After the packaging paper tube is produced, its length is generally long, so it needs to be cut by slitting equipment to adapt to different products. Of course, the length of the packaging paper tube required for different products is also different.

[0004] When the blades on traditional slitting equipment slit packaging paper tubes, they are generally clamped by a clamping device and then cut by the blades. When facing hollow packaging paper tubes, since there is no support inside, they are easily squeezed when contacting the blades, resulting in deformation of the cutting part, which seriously affects the processing quality of the packaging paper tubes.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a slitting device for packaging paper tubes. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a packaging paper tube slitting device.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a slitting device for packaging paper tubes, comprising a slitting platform for supporting and installing a slitting component, a transmission component for driving a rotating rod to rotate is installed on one side of the slitting platform, a knife groove is opened on the outer wall of the rotating rod near the end, a telescopic component for driving a blade to move to the knife groove position is installed on the side end of the slitting platform perpendicular to the transmission component, a fixing component is provided at the end of the rotating rod, after the packaging paper tube is inserted into the rotating rod, it is fixed to the rotating rod by the fixing component, and then the blade is driven to move and inserted into the knife groove by the telescopic component, and then the rotating rod and the packaging paper tube are driven by the transmission component to rotate, thereby slitting the packaging paper tube.

[0008] Preferably, the transmission assembly includes an L-shaped plate welded to one side of the slitting platform, and the top of the L-shaped plate is fixedly connected to a shell, a motor for driving an internal transmission gear to rotate is installed on one side of the shell, and the upper and lower sides of the transmission gear are meshed with driven gears, the surfaces of the transmission gear and the driven gear are fixed to the head of the rotating rod, and the back side of the driven gear is rotatably connected to the inner surface of the shell through a bearing.

[0009] Preferably, telescopic components and blades are installed on both side ends of the slitting platform that are perpendicular to the transmission assembly.

[0010] Preferably, the telescopic component comprises a connecting plate welded on the vertical side ends of the slitting platform and the transmission assembly, and a cylinder for driving the blade to move back and forth is fixedly connected to the surface of the connecting plate.

[0011] Preferably, the fixing assembly comprises a transverse plate fixed to the end of the rotating rod, the upper and lower sides of the transverse plate are fixedly connected to electric hydraulic rods, and the transmission part of the electric hydraulic rod is fixedly connected to an arc plate.

[0012] Preferably, friction grooves are provided on the surface of the arc-shaped plate, thereby increasing the friction force generated by the contact between the arc-shaped plate and the packaging paper tube, so that the fixation is more secure.

[0013] Preferably, a chain plate transmission belt machine is provided in the middle part of the slitting platform, a blocking plate is fixedly connected to a single chain plate of the chain plate transmission belt machine, and a through hole is opened inside the blocking plate for the rotating rod to pass through, so as to facilitate continuous slitting of the packaging paper tube.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model fixes the packaging paper tube and the rotating rod through a fixing component. After the fixing is completed, the telescopic component drives the movement of the blade to insert the blade into the knife slot. At the same time, the blade also passes through the packaging paper tube to cut a hole in the packaging paper tube. Then, the transmission component drives the rotating rod and the packaging paper tube to rotate, so that the packaging paper tube rotates 360 degrees, so that the blade cuts one circle of the packaging paper tube to cut out a packaging paper tube of appropriate length. In this way, the knife slot moves along the blade to cut the packaging paper tube, and the other parts of the packaging paper tube are supported by the rotating rod to avoid deformation of the cutting part, thereby solving the problem that when the existing equipment in the background technology faces a hollow packaging paper tube, it is easy to be squeezed when it contacts the blade due to the lack of support inside, resulting in deformation of the cutting part.

[0016] 2. The utility model drives the blocking plate to move back and forth through a chain plate transmission belt machine. The through hole on the blocking plate passes through the rotating rod, so that it can move back and forth along the rotating rod, thereby adjusting its position. In this way, when the packaging paper tube is inserted into the rotating rod and abuts against the blocking plate, a suitable cutting position of the packaging paper tube can be obtained, thereby performing processing more quickly.

[0023] like Figure 1-4 As shown, the utility model provides a slitting device for packaging paper tubes, including a slitting platform 1 for supporting and installing a slitting component, a transmission component 2 for driving a rotating rod 3 to rotate is installed on one side of the slitting platform 1, a knife groove 4 is opened on the outer wall of the rotating rod 3 near the end, a telescopic component 5 for driving a blade 7 to move to the position of the knife groove 4 is installed on the side end of the slitting platform 1 perpendicular to the transmission component 2, a fixing component 6 is provided at the end of the rotating rod 3, after the packaging paper tube is inserted into the rotating rod 3, it is fixed to the rotating rod 3 by the fixing component 6, and then the blade 7 is driven by the telescopic component 5 to move and insert the blade 7 into the knife groove 4, and then the rotating rod 3 and the packaging paper tube are driven by the transmission component 2 to rotate, thereby slitting the packaging paper tube.

[0024] When the present slitting device is used, the staff first inserts the packaging paper tube (hollow packaging paper tube) into each rotating rod 3. After the insertion is completed, the slitting length is adjusted, that is, the packaging paper tube of the required slitting length is passed through the knife groove 4. After the adjustment is completed, the packaging paper tube and the rotating rod 3 are fixed by the fixing component 6. After the fixing is completed, the movement of the blade 7 is driven by the telescopic component 5 to insert the blade 7 into the knife feed groove 4. At the same time, the blade 7 also passes through the packaging paper tube to cut a hole in the packaging paper tube. Then the transmission component 2 drives the rotating rod 3 and The rotation of the packaging paper tube causes the packaging paper tube to rotate 360 ​​degrees, so that the blade 7 cuts the packaging paper tube around one circumference to cut out a packaging paper tube of appropriate length. In this way, the knife groove 4 moves along the blade 7 to cut the packaging paper tube, and the other parts of the packaging paper tube are supported by the rotating rod 3 to avoid deformation of the cutting part (the knife groove 4 is only enough to accommodate the small blade 7). After the processing is completed, the blade 7 is moved away from the knife groove 4, and the fixing component 6 on the packaging paper tube is cancelled, and the cut packaging paper tube can be removed.

[0025] Furthermore, telescopic parts 5 and blades 7 are installed on the two side ends perpendicular to the slitting platform 1 and the transmission assembly 2, so that the packaging paper tube is cut by two blades 7 at the same time, increasing the contact between the blades 7 and the packaging paper tube to avoid incomplete cutting.

[0026] In addition, a chain plate transmission belt machine 8 is provided in the middle part of the cutting platform of the utility model, and a blocking plate 9 is fixedly connected to a single chain plate of the chain plate transmission belt machine 8. A through hole 10 for the rotating rod 3 to pass through is opened inside the blocking plate 9, that is, the blocking plate 9 is driven to move back and forth by the chain plate transmission belt machine 8, and the through hole 10 on the blocking plate 9 passes through the rotating rod 3, so that it can move back and forth along the rotating rod 3, thereby adjusting its position (adjusting to a position corresponding to the cutting length of the packaging paper tube), so that when the packaging paper tube is inserted into the rotating rod 3 and abuts against the blocking plate 9, a suitable cutting position for the packaging paper tube can be obtained, thereby facilitating continuous cutting of the packaging paper tube.

[0027] The specific structure of the transmission assembly 2; the transmission assembly 2 includes an L-shaped plate 201 welded on one side of the slitting platform 1, and the top of the L-shaped plate 201 is fixedly connected to a shell 202, and a motor 205 is installed on one side of the shell 202 to drive the internal transmission gear 203 to rotate, and the upper and lower sides of the transmission gear 203 are meshed with driven gears 204, the surfaces of the transmission gear 203 and the driven gear 204 are fixed to the head of the rotating rod 3, and the back of the driven gear 204 is rotatably connected to the inner surface of the shell 202 through a bearing, that is, the transmission gear 203 is driven by the motor 205 to rotate, and the transmission gear 203 drives the driven gear 204 to rotate, thereby driving the three rotating rods 3 to rotate at the same time. It should be noted that the scope of protection of the utility model does not only refer to three rotating rods 3, and more rotating rods 3 can be connected through gear transmission. If other patents only adjust the number of rotating rods 3, they are still within the scope of protection of the utility model.

[0028] The specific structure of the telescopic component 5: the telescopic component 5 includes a connecting plate 501 welded on the vertical side ends of the slitting platform 1 and the transmission assembly 2, and a cylinder 502 for driving the blade 7 to move back and forth is fixedly connected to the surface of the connecting plate 501, that is, the blade 7 is driven to move back and forth toward the position of the knife groove 4 or away from the position of the knife groove 4 through the telescopic component 5.

[0029] Specific structure of the fixing component 6: the fixing component 6 includes a transverse plate 601 fixed to the end of the rotating rod 3, and the upper and lower sides of the transverse plate 601 are fixedly connected with electric hydraulic rods 602, and the transmission part of the electric hydraulic rod 602 is fixedly connected with an arc plate 603, that is, after the packaging paper tube is inserted into the rotating rod 3 and the cutting position is adjusted, the two arc plates 603 are driven to move to both sides by the two electric hydraulic rods 602, and the arc plates 603 move to both sides to press against the inner side wall of the packaging paper tube, and fix the packaging paper tube and the rotating rod 3 from the inside through the clamping force (the packaging paper tube is longer before cutting). It is best to have friction grooves on the surface of the arc plate 603 to increase the friction generated by its contact with the packaging paper tube to improve the firmness of the packaging paper tube.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above.
