Description

Technical Field

[0001] The utility model relates to the technical field of resin paper tube processing equipment, in particular to high-strength seamless resin paper tube extrusion equipment. Background Art

[0002] As a new type of packaging material, resin paper tubes have been widely used in industries such as wires and cables, paper products, food and tobacco due to their durability, waterproof and oil-proof, and long service life. When producing resin paper tubes, an extruder is required to extrude and shape them.

[0003] At present, the extruders used in processing resin paper tubes need to clamp the two ends of the paper tube with a clamp when extruding the paper tube, and then drive the paper tube to rotate and cooperate with the mold for extrusion. Therefore, the lateral force on the paper tube will be relatively large. If the clamping is loose, it is easy to fall off. If the clamping is too tight, it is easy to cause the paper tube to be subjected to excessive force and deform, affecting the yield rate, and the operation is also relatively inconvenient. Summary of the Invention

[0004] The utility model provides a high-strength seamless resin paper tube extrusion device, which does not require clamping the two ends of the paper tube during use, thereby preventing the paper tube from falling off or deforming, improving the yield rate, and is also very convenient to operate.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] The utility model provides a high-strength seamless resin paper tube extrusion device, comprising: a base 1;

[0029] A side support plate 2 is welded on both sides of the top of the base 1, and the base 1 is used to support the side support plates 2; a No. 1 squeezing roller 3 and a No. 2 squeezing roller 4 are rotatably installed between the two side support plates 2, and the No. 1 squeezing roller 3 and the No. 2 squeezing roller 4 are used to support the resin paper tube, and the No. 1 squeezing roller 3 and the No. 2 squeezing roller 4 can also squeeze the resin paper tube during processing; a stepper motor 5 is installed on the left side of the top of the base 1, and the right end of the main shaft of the stepper motor 5 is fixedly connected to the left end of the No. 2 squeezing roller 4, and the stepper motor 5 is used to drive the No. 2 squeezing roller 4 to rotate; an air duct 6 is also connected to one side of the two side support plates 2. During installation, one end of one of the air ducts 6 can be connected to the air outlet of the hot air blower, and one end of the other air duct 6 can be connected to the air inlet of the hot air blower. During working hours, the external hot air blower can be turned on. During this process, the hot air blower will blow the hot air into the annular cavity inside the No. 1 squeezing roller 3 through one of the air ducts 6 and flow to the other side, so that the outer wall of the No. 1 squeezing roller 3 can be heated. Finally, the air will be discharged outward through another air duct 6 and continue to enter the hot air blower for heating, reducing heat loss; a support block 7 is slidably installed on each of the two side support plates 2, and the support block 7 is used to rotate and support the No. 3 squeezing roller 8; a No. 3 squeezing roller 8 is rotatably installed between the two support blocks 7, and the No. 3 squeezing roller 8 is used to extrude the resin paper tube; an electric cylinder 9 is also installed in the middle position of the top of the two side support plates 2, and the bottom end of the electric cylinder 9 is fixedly connected to the middle position of the top of the support block 7. The electric cylinder 9 can adjust the height of the support block 7 when it is extended and retracted.

[0030] In the embodiment of the present disclosure, Figure 5 and Figure 6 As shown, a rectangular opening is provided above the side support plate 2, and a vertical raised strip is provided on the front and rear sides of the support block 7. A corresponding vertical guide groove is also provided on the front and rear sides of the rectangular opening above the side support plate 2. When the support block 7 slides up and down in the side support plate 2, the height of the No. 3 squeezing roller 8 can be adjusted. At the same time, the vertical raised strips on the front and rear sides of the support block 7 can slide up and down in the vertical guide grooves on the front and rear sides of the rectangular opening above the side support plate 2, ensuring that the support block 7 slides up and down stably.

[0031] In the embodiment of the present disclosure, Figure 1-Figure 3 As shown, the outer diameters of the No. 1 squeezing roller 3 and the No. 2 squeezing roller 4 are equal and located at the same height, and the No. 1 squeezing roller 3 and the No. 2 squeezing roller 4 are symmetrical front to back between the two side support plates 2. When in use, the resin paper tube to be squeezed can be placed in the middle position of the top of the No. 1 squeezing roller 3 and the No. 2 squeezing roller 4, and then the two electric cylinders 9 are controlled to extend synchronously to push the outer wall of the No. 3 squeezing roller 8 to fit tightly against the outer wall of the resin paper tube, so that the outer wall of the resin paper tube can be squeezed.

[0032] In the embodiment of the present disclosure, Figure 1-Figure 3 As shown, the third squeezing roller 8 is located at the top middle position between the No. 1 squeezing roller 3 and the No. 2 squeezing roller 4. When in use, the resin paper tube to be squeezed can be placed at the top middle position between the No. 1 squeezing roller 3 and the No. 2 squeezing roller 4, and then the two electric cylinders 9 are controlled to extend synchronously to push the outer wall of the No. 3 squeezing roller 8 to fit tightly against the outer wall of the resin paper tube. Therefore, the outer wall of the resin paper tube can be squeezed, and the No. 3 squeezing roller 8 will fit tightly against the top middle position of the resin paper tube to prevent the resin paper tube from loosening or even falling off.

[0033] In the embodiment of the present disclosure, Figure 4 As shown, an annular cavity is provided inside the No. 1 squeezing roller 3, and an opening is provided at both the left and right ends of the No. 1 squeezing roller 3 to communicate with the inner cavity. When the seamless resin paper tube is extruded, the external hot air blower can be turned on. During this process, the hot air blower will blow hot air into the annular cavity inside the No. 1 squeezing roller 3 through one of the air guide tubes 6 and flow to the other side, thereby heating the outer wall of the No. 1 squeezing roller 3.

[0034] In the embodiment of the present disclosure, Figure 5 As shown, the air ducts 6 are all installed on one side of the circular hole of the No. 1 squeezing roller 3 on the side support plate 2, and the two ends of the No. 1 squeezing roller 3 are respectively embedded in the cavities inside the two air ducts 6. During installation, one end of one of the air ducts 6 can be connected to the air outlet of the hot air blower, and one end of the other air duct 6 can be connected to the air inlet of the hot air blower. When the seamless resin paper tube is extruded, the external hot air blower can be turned on. During this process, the hot air blower will blow the hot air through one of the air ducts 6 into the annular cavity inside the No. 1 squeezing roller 3 and flow to the other side, thereby heating the outer wall of the No. 1 squeezing roller 3. Finally, the air will be discharged outward through the other air duct 6 and continue to enter the hot air blower for heating, reducing heat loss.

[0035] Example 2, based on Example 1, Figures 1-6 As shown, the outer sides of the No. 1 squeezing roller 3, the No. 2 squeezing roller 4 and the No. 3 squeezing roller 8 are all wrapped with a layer of rubber, and the No. 1 squeezing roller 3 is made of copper tube. When processing the resin paper tube, the No. 1 squeezing roller 3, the No. 2 squeezing roller 4 and the No. 3 squeezing roller 8 will always squeeze the resin paper tube. Therefore, the rubber on the outer side of the squeezing roller can increase the friction force to avoid slipping, and the copper No. 1 squeezing roller 3 can also improve the heat conduction effect.

[0036] The working principle of this embodiment: during installation, the base 1 can be fixed on the processing table, and the stepper motor 5 and the electric cylinder 9 are connected to the external controller and the power supply, and then one end of one of the air guide tubes 6 is connected to the air outlet of the hot air blower, and one end of the other air guide tube 6 is connected to the air inlet of the hot air blower. When the seamless resin paper tube is extruded, the external hot air blower can be turned on. During this process, the hot air blower will blow the hot air through one of the air guide tubes 6 into the annular cavity inside the No. 1 extrusion roller 3 and flow to the other side, thereby heating the outer wall of the No. 1 extrusion roller 3. Finally, the air will be discharged outward through the other air guide tube 6 and continue to enter the hot air blower for heating, reducing heat. The loss is reduced, and then the resin paper tube to be squeezed can be placed in the middle position of the top of the No. 1 squeezing roller 3 and the No. 2 squeezing roller 4, and then the two electric cylinders 9 are controlled to extend synchronously to push the support block 7 to slide downward under the support of the side support plate 2, until the outer wall of the No. 3 squeezing roller 8 is in close contact with the outer wall of the resin paper tube, and then the stepper motor 5 can be controlled to drive the No. 2 squeezing roller 4 to rotate slowly. During the rotation of the No. 2 squeezing roller 4, the resin paper tube will also be driven to rotate synchronously. Moreover, because the No. 1 squeezing roller 3, the No. 2 squeezing roller 4 and the No. 3 squeezing roller 8 are always squeezing the resin paper tube, and the heat on the outer wall of the No. 1 squeezing roller 3 will also heat the resin paper tube, so the resin paper tube can complete the extrusion process.
