Description

Technical Field

[0001] This utility model belongs to the field of paper tube processing technology, and in particular relates to a cutting device for POY paper tubes. Background Technology

[0002] POY paper tubes are a common paper material made from base paper and polyester filaments. They are commonly used in logistics, decoration, and other fields. During production and processing, they need to be cut to facilitate transportation and storage.

[0003] Chinese patent CN217801943U discloses a cutting device for paper tube processing, including a cutting box. A motor is fixedly mounted on the upper side of the cutting box, and a paper tube shaft is rotatably connected inside the cutting box. The paper tube shaft is fixedly connected to the motor output shaft. A rotating shaft is also rotatably connected to the cutting box, and a fan blade is fixedly mounted at the end of the rotating shaft. The rotating shaft is connected to the paper tube shaft via a transmission connection. A fixed shaft is also fixedly mounted inside the cutting box. This cutting device for paper tube processing, by setting a rotating shaft rotatably connected to the cutting box, a fan blade at the end of the rotating shaft, and a collection bucket detachably mounted on the cutting box, achieves the function of blowing the cut paper scraps into the collection bucket by rotating the fan blade. This solves the problem in the prior art that requires manual cleaning of paper scraps, which increases the workload and affects the health of workers.

[0004] The aforementioned patent has the following problems: This patent has some drawbacks in its use. Specifically, the process involves fitting a paper tube onto a paper tube shaft and using a drive motor to rotate the shaft, controlling the handle to bring the cutting blade against the paper tube surface for cutting. However, in actual cutting, both the inner wall of the paper tube and the surface of the paper tube shaft are smooth (otherwise, the tube would not fit). This can cause slippage and displacement of the paper tube during cutting, resulting in skewed cuts and affecting the cutting quality. Therefore, we propose a POY paper tube cutting device. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for POY paper tubes to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a cutting device for POY paper tubes, including a box body, a rotating opening on one side of the box body, a paper tube shell rotatably installed in the rotating opening, an insertion opening on one side of the box body, a plurality of sliding holes on the surface of the paper tube shell, a support column slidably installed in each of the plurality of sliding holes, a positioning plate fixedly installed at one end of the support column near the surface of the paper tube shell, and a pneumatic component slidably installed on the inner wall of the paper tube shell; A collection box is fixedly installed on the inner bottom wall of the box body, and a sliding rod is fixedly installed on one side of the box body. A cutting component is slidably installed on the surface of the sliding rod.

[0007] In this technical solution, a rotating opening is provided on one side of the box, through which a paper tube shell is rotatably mounted to support and fix the POY paper tube to be cut. An insertion opening is also provided on one side of the box for inserting the paper tube; the radius of the insertion opening is much larger than the radius of the paper tube shell. Two sets of sliding holes are formed circumferentially on the surface of the paper tube shell, each set having three sliding holes spaced at equal angles. A support column is slidably installed in each sliding hole. A positioning plate is fixedly installed at one end of the support column near the outer surface of the paper tube shell. The positioning plate has an arc-shaped surface that conforms to the POY paper tube. A pneumatic assembly is slidably installed on the inner wall of the paper tube shell to drive the positioning plate. A collection box is fixedly installed on the inner bottom wall of the box to collect cutting debris. A sliding rod is fixedly installed on one side of the box, and a cutting assembly is slidably installed on its surface to perform the cutting operation. The POY paper tube is inserted through the insertion opening onto the paper tube shell, and then the pneumatic assembly drives the support column and positioning plate to move radially outward, tightening the paper tube from the inside for secure fixing. Subsequently, the paper tube shell is driven to rotate, while the cutting component moves along the slide bar to cut the paper tube. The cutting debris falls into the collection box below, and through the internal clamping mechanism, the problem of paper tube slippage and displacement during traditional smooth mandrel cutting is solved, ensuring cutting accuracy and quality.

[0008] In the above technical solution, the pneumatic assembly further includes two pneumatic pistons, both of which are slidably mounted on the inner wall of the paper tube shell. A common connecting rod is fixedly mounted between the two pneumatic pistons. A guide cone is fixedly mounted on one side of each of the two pneumatic pistons and sleeved on the connecting rod. A guide ball head is fixedly mounted on one end of one of the plurality of support columns. A return spring is sleeved on the surface of the support column and is located between the guide ball head and the inner wall of the paper tube shell.

[0009] In this technical solution, two pneumatic pistons are slidably mounted on the inner wall of the paper tube shell. A common connecting rod is fixedly installed between the two pneumatic pistons to ensure synchronous movement. A guide cone is fixedly installed on one side of each pneumatic piston, and the guide cone is sleeved on the connecting rod. A guide ball head is fixedly installed at one end of each support column extending into the inner cavity of the paper tube shell. A return spring is also sleeved on the surface of each support column, located between the guide ball head and the inner wall of the paper tube shell. When compressed air enters the inner cavity of the paper tube shell through the pneumatic connector, it pushes the two pneumatic pistons to move axially along the connecting rod. The pneumatic pistons drive the guide cones to move synchronously. The conical surface of the guide cones compresses multiple guide ball heads, converting the axial movement of the pistons into the radial movement of the support columns, thereby pushing the positioning plate to outward and tighten the inner wall of the paper tube. After depressurization, under the action of the return spring, the support columns and positioning plates automatically retract, releasing the fixation. The pistons can then drive the three support points to synchronously and evenly tighten the paper tube, ensuring reliable fixation, uniform force distribution, and preventing paper tube deformation.

[0010] In the above technical solution, a sealing cover is fixedly installed on one side of the paper tube shell, and a pneumatic connector is rotatably installed on the sealing cover.

[0011] In this technical solution, an external air supply pipeline is connected to a pneumatic connector. Compressed air enters the rotating paper tube shell through the pneumatic connector, driving the pneumatic piston. The sealing cover ensures the sealing of the inner cavity of the paper tube shell and prevents air leakage. The rotating installation of the pneumatic connector allows the paper tube shell to rotate freely in the air-ventilated state, ensuring the normal operation of the pneumatic system when the equipment is running.

[0012] In the above technical solution, a drive motor is further fixedly installed on one side of the housing, and the output end of the drive motor is coaxially and fixedly connected to one end of the drive wheel.

[0013] In this technical solution, the drive motor's output shaft directly drives the drive wheel to rotate, thereby driving the entire paper tube shell and the POY paper tube fixed on it to rotate together, providing the necessary drive for cutting.

[0014] In the above technical solution, further, a transmission rod is rotatably installed on the inner wall of the collection box via a bearing, a fan blade is fixedly installed on the surface of the transmission rod, an exhaust port is opened on one side of the box, the fan blade is located inside the exhaust port, an air inlet is opened on one side of the collection box, fan blades are fixedly installed inside both the exhaust port and the air inlet, and filter screens are fixedly installed on the inner walls of both the exhaust port and the air inlet.

[0015] In this technical solution, an air inlet is provided on one side of the collection box. Filters are fixedly installed in both the exhaust and air inlets, with a fan blade positioned between the two filters. When the drive rod rotates the fan blade, a negative pressure is generated in the area above the collection box. Paper scraps generated during cutting, while falling due to gravity, are guided by this suction force and effectively drawn into the collection box. The filters prevent debris from entering the fan or being discharged outside the box, maintaining the cleanliness of the equipment's interior and surrounding environment.

[0016] In the above technical solution, a drive wheel is fixedly installed on the surface of the paper tube shell, a transmission wheel is fixedly installed on the surface of the transmission rod, and the drive wheel and the transmission wheel are fitted together by the same transmission belt.

[0017] In this technical solution, a partition is installed on the inner wall of the collection box to separate the drive wheel from the drive belt. The drive rod passes through the partition to prevent debris from affecting the engagement. When the paper tube shell rotates, it drives the drive wheel on it to rotate. The drive wheel transmits power to the drive wheel through the drive belt, thereby driving the drive rod and the fan blade to rotate.

[0018] In the above technical solution, the cutting component further includes a sliding ring, which is slidably mounted on the surface of the slide rod. A connecting shaft is fixedly mounted on one side of the sliding ring, and a cutter is rotatably mounted on the connecting shaft. The cutter is located above the paper tube shell.

[0019] In this technical solution, the operator manually pushes the sliding ring along the slide rod to adjust the axial position of the cutter. Then, the cutter is pressed down or rotated to make it contact the rotating paper tube, thus completing the cutting.

[0020] The beneficial effects of this utility model are: The POY paper tube cutting device injects gas into the paper tube shell through a pneumatic source, which pushes one of the pneumatic pistons to move. Under the action of the connecting rod, it drives another pneumatic piston to move synchronously. The pneumatic pistons drive two guide cones to move synchronously. The guide cones simultaneously squeeze three guide ball heads. The guide ball heads drive the corresponding support columns to move. The support columns drive the corresponding positioning plates to move, so that the positioning plates extend to the outside of the paper tube shell and fit against the inner wall of the POY paper tube, fixing and positioning the POY paper tube. This prevents the inner wall of the POY paper tube from slipping on the surface of the paper tube shell during the cutting process, which would affect the cutting effect. Attached Figure Description

Two sets of sliding holes are formed circumferentially on the surface of the paper tube shell 2, each set having three equally spaced sliding holes. A support column 14 is slidably installed in each sliding hole. A positioning plate 15 is fixedly installed at one end of the support column 14 near the outer surface of the paper tube shell 2.

Then, driven by a pneumatic component, the support column 14 and the positioning plate 15 are moved radially outward, tightening the paper tube from the inside for a secure fixation. Subsequently, the paper tube shell 2 is driven to rotate, while the cutting component moves along the slide bar 6 to cut the paper tube. The cutting debris falls into the collection box 5 below. The internal tightening mechanism solves the problem of paper tube slippage and displacement during traditional smooth mandrel cutting, ensuring cutting accuracy and quality.

A return spring 16 is also sleeved on the surface of each support column 14, located between the guide ball head 13 and the inner wall of the paper tube shell 2. When compressed air enters the inner cavity of the paper tube shell 2 through the pneumatic connector 10, it pushes the two pneumatic pistons 7 to move axially along the connecting rod 8. The pneumatic pistons 7 drive the guide cones 12 to move synchronously. The conical surface of the guide cone 12 compresses multiple guide ball heads 13, converting the axial movement of the piston into the radial movement of the support column 14, thereby pushing the positioning plate 15 to outwardly tighten the inner wall of the paper tube. After depressurization, the support column 14 and positioning plate 15 automatically retract under the action of the reset spring 16, releasing the fixation. The piston can then drive the three support points to synchronously and evenly tighten the paper tube, ensuring reliable fixation, uniform force distribution, and preventing paper tube deformation.

[0030] The external air supply line is connected to the pneumatic connector 10.

[0034] The collection box 5 has an air inlet on one side. Filters 21 are fixedly installed in both the exhaust and air inlets, with a fan blade 22 positioned between them. When the drive rod 20 rotates the fan blade 22, a negative pressure is generated in the area above the collection box 5. Paper scraps generated during cutting, while falling due to gravity, are guided by this suction and effectively drawn into the collection box 5.

[0036] The inner wall of the collection box 5 is equipped with a partition to separate the drive wheel 19 from the drive belt 18. The drive rod 20 passes through the partition to prevent debris from affecting the engagement. When the paper tube shell 2 rotates, it drives the drive wheel 11 on it to rotate.

[0037] Example 7: This example provides a cutting device for POY paper tubes. In addition to the technical solutions of the above examples, it also has the following technical features: the cutting component includes a sliding ring 23, which is slidably mounted on the surface of the slide rod 6. A connecting shaft 24 is fixedly mounted on one side of the sliding ring 23, and a cutter 17 is rotatably mounted on the connecting shaft 24. The cutter 17 is located above the paper tube shell 2.

[0038] The operator manually pushes the sliding ring 23 along the slide rod 6 to adjust the axial position of the cutter 17. Then, the cutter 17 is pressed down or rotated to make it contact the rotating paper tube, thus completing the cutting.

[0039] Working principle: When using the device, first insert the POY paper tube to be cut into the insertion port 3 and place the paper tube shell 2 on the inner wall of the POY paper tube. After full insertion, connect the pneumatic connector 10 to the pneumatic source, then turn on the pneumatic source. Gas is injected into the paper tube shell 2 and pushes one of the pneumatic pistons 7 to move. Under the action of the connecting rod 8, it drives the other pneumatic piston 7 to move synchronously. The pneumatic piston 7 drives the two guide cones 12 to move synchronously. The guide cones 12 simultaneously squeeze the three guide ball heads 13. The guide ball heads 13 drive the corresponding support column 14 to move. The support column 14 drives the corresponding positioning plate 15 to move, so that the positioning plate 15 extends to the outside of the paper tube shell 2 and fits against the inner wall of the POY paper tube to fix and position the POY paper tube. Once the cutting position of the POY paper tube is determined, it is marked with a marker pen. Then, the drive motor 4 is started. The output of the drive motor 4 drives the paper tube shell 2 to rotate at high speed. The cutter 17 is manually pulled and moves horizontally through the cooperation of the sliding ring 23 and the slide rod 6. The cutter 17 is moved horizontally through the connecting shaft 24 to position it at the cutting line. The cutter 17 is slowly pressed down to cut the paper tube. During the cutting process, debris is generated. At this time, the paper tube shell 2 drives the drive wheel 11 to rotate. The drive wheel 11 drives the transmission wheel 19 to rotate through the transmission belt 18. The transmission wheel 19 drives the transmission rod 20 to rotate. The transmission rod 20 drives the fan blade 22 to rotate, drawing air from the top of the collection box 5 and expelling it from the exhaust port, creating a negative pressure in the collection box 5. When the debris falls, it will enter the collection box 5 under the influence of the negative pressure and be collected by the two filters 21. After cutting is completed, turn off the drive motor 4, unplug the external pneumatic source, and drive the guide ball head 13 to reset under the action of multiple reset springs 16, which in turn drives the positioning plate 15 and the guide cone 12 to reset, thereby releasing the positioning of the POY paper tube, removing the POY paper tube, and completing the cutting.
