Description

Technical Field

[0001] This application relates to the field of packaging equipment technology, and in particular to a roll forming device and packaging machine. Background Technology

[0002] Currently, in the paper roll packaging production process, after the paper roll is wrapped in packaging film, the two ends of the folded packaging film need to be heat-sealed. This is mostly done by attaching a heating belt to both ends of the packaging film and then heating and sealing it at high temperature.

[0003] Due to the continuous high temperature and high speed operation, heating belts inevitably become consumables. In order to adapt to all production specifications of general-purpose machines, heating belts are usually designed to the maximum height specification. When continuously producing products of the same specification, the paper roll clamping heat sealing only utilizes a part of the belt area. Even if the area is worn to the point of being unusable, a new heating belt can only be replaced. The remaining unsealed areas cannot be utilized, resulting in a certain waste of resources. Utility Model Content

[0004] Therefore, it is necessary to provide a roll forming device and packaging machine to address the problem that wear and tear of the heating belt in existing packaging machines affects normal use.

[0005] A roll forming apparatus is used for sealing and conveying a paper roll with a packaging film. The roll forming apparatus includes: a conveying mechanism for conveying the paper roll along a first direction; and a pressing mechanism disposed above the conveying mechanism for sealing the paper roll with the packaging film. The pressing mechanism includes a pressing component and an adjusting component. The pressing component is disposed on at least one side of the conveying mechanism along a second direction. The adjusting component is connected to the pressing component and is used to adjust the position of the pressing component in a third direction, wherein the third direction intersects the first direction and the second direction in pairs, and the three directions are not coplanar.

[0006] The aforementioned roll forming device can seal the packaging film of paper rolls and transport the paper rolls. When the pressing belt is severely worn and / or the sealing effect of the packaging film of the paper roll is poor, the position of the pressing component in the height direction can be adjusted by the adjusting component so that other areas of the pressing component contact the packaging film of the paper roll, so that the packaging film of the paper roll can be effectively sealed. When some areas of the pressing component are worn too much, the unworn areas can be used, thereby greatly improving the utilization efficiency of the pressing component and extending the overall service life of the roll forming device.

[0007] In some embodiments, the pressing assembly includes a mounting base and at least two hot-pressing components, each of the hot-pressing components being disposed on the mounting base and distributed on opposite sides of the conveying mechanism along the second direction, and the adjusting assembly being connected to the mounting base and used to adjust the position of the mounting base in the third direction.

[0008] In some embodiments, each of the hot pressing components includes a pressing belt, a pressing drive, a driving wheel, and a driven wheel. The driving wheel and the driven wheel are spaced apart along the first direction. The pressing belt is sleeved over the driving wheel and the driven wheel. The pressing belt is provided with a heating element and is used to heat seal the packaging film of the paper roll. The pressing drive is connected to the driving wheel and the driven wheel respectively. Under the drive of the pressing drive, the driving wheel and the driven wheel rotate synchronously and drive the pressing belt to rotate.

[0009] In some embodiments, the pressing belt has a first hot-pressing region and a second hot-pressing region disposed adjacent to each other in the third direction, and the adjusting component is capable of adjusting the position of the mounting base in the third direction so that the packaging film of the paper roll abuts against the first hot-pressing region or the second hot-pressing region.

[0010] In some embodiments, in the first direction, the length of the pressing belt is less than or equal to the length of the conveying mechanism, and the length of the pressing belt is greater than the length of the paper roll.

[0011] In some embodiments, the adjustment assembly includes an adjustment drive and an adjustment screw, the mounting base has a screw hole, the adjustment screw passes through the screw hole and is threaded into the screw hole, and the adjustment drive is connected to the adjustment screw; under the drive of the adjustment drive, the adjustment screw rotates and drives the mounting base to move along the third direction.

[0012] In some embodiments, the pressing mechanism further includes a controller and a detection element, wherein the controller is electrically connected to the detection element and the adjustment drive element respectively; the detection element is used to detect the wear degree of the pressing belt and / or the sealing effect of the packaging film of the paper roll, and the controller controls the operation of the adjustment drive element according to the detection result of the detection element.

[0013] In some embodiments, the pressing assembly further includes a translation drive connected to each of the hot presses and used to drive each of the hot presses to move along the second direction to adjust the position of each of the hot presses in the second direction.

[0014] In some embodiments, the conveying mechanism includes at least two conveyor belts, each extending along the first direction and arranged side-by-side along the second direction.

[0015] A packaging machine includes the roll forming device described above.

[0016] The aforementioned packaging machine can seal the packaging film of paper rolls and transport the paper rolls. When the pressing belt is severely worn and / or the sealing effect of the packaging film of the paper roll is poor, the position of the pressing component in the height direction can be adjusted by adjusting the component so that other areas of the pressing component contact the packaging film of the paper roll, so that the packaging film of the paper roll can be effectively sealed. When some areas of the pressing component are worn too much, the unworn areas can be used, thereby greatly improving the utilization efficiency of the pressing component and extending the overall service life of the roll forming device.

[0033] Please refer to Figures 1 to 3 In one embodiment, the roll forming apparatus is used to encapsulate the packaging film 20 of the paper roll 10 and to transport the paper roll 10. The roll forming apparatus includes a conveying mechanism 100 and a pressing mechanism 200. The conveying mechanism 100 is used to transport the paper roll 10 along a first direction. The pressing mechanism 200 is disposed above the conveying mechanism 100 and is used to encapsulate the packaging film 20 of the paper roll 10. The pressing mechanism 200 includes a pressing component 300 and an adjusting component 400. The pressing component 300 is disposed on at least one side of the conveying mechanism 100 along a second direction. The adjusting component 400 is connected to the pressing component 300 and is used to adjust the position of the pressing component 300 in a third direction. The third direction intersects the first direction and the second direction in pairs and the three directions are not coplanar.

[0034] It should be noted that the first direction is Figures 1 to 3 The X direction shown is the length direction of the roll forming device; the second direction is... Figures 1 to 3 The Y direction shown is the width direction of the roll forming device; the third direction is... Figures 1 to 3 The Z direction shown is the height direction of the roll forming device.

[0035] Here, the paper roll 10 wrapped with packaging film 20 is first placed on the conveying mechanism 100, and then the hot pressing area of ​​the pressing assembly 300 is brought into contact with the packaging film 20 of the paper roll 10. The pressing assembly 300 is used to press the packaging film 20 of the paper roll 10 along... Figures 1 to 3 The two ends in the Y direction are sealed, and then the conveying mechanism 100 is used to transport them along the Y direction. Figure 1 The X-direction output shows a paper roll 10 with the packaging film 20 already sealed. After a period of use, the wear of the pressing belt 321 and / or the sealing effect of the packaging film 20 of the paper roll 10 can be detected. If the pressing belt 321 is severely worn and / or the sealing effect of the packaging film 20 of the paper roll 10 is poor, the position of the pressing component 300 in the height direction can be adjusted by adjusting the component 400 so that other areas of the pressing component 300 contact the packaging film 20 of the paper roll 10, so that the packaging film 20 of the paper roll 10 can be effectively sealed.

[0036] The aforementioned roll forming apparatus can seal the packaging film 20 of the paper roll 10 and transport the paper roll 10. When the pressing belt 321 is severely worn and / or the sealing effect of the packaging film 20 of the paper roll 10 is poor, the position of the pressing component 300 in the height direction can be adjusted by the adjusting component 400 so that other areas of the pressing component 300 contact the packaging film 20 of the paper roll 10, so that the packaging film 20 of the paper roll 10 can be effectively sealed. When some areas of the pressing component 300 are worn too much, the unworn areas can be used, thereby greatly improving the utilization efficiency of the pressing component 300 and extending the overall service life of the roll forming apparatus.

[0037] In the embodiments of this application, the conveying mechanism 100 is a component for conveying the paper roll 10 along a first direction, and the conveying mechanism 100 can adopt various structural forms. For example, the conveying mechanism 100 can be a structure including a conveyor belt 110, which is used to convey the paper roll 10.

[0038] In the embodiments of this application, the pressing mechanism 200 is a component for sealing the packaging film 20 of the paper roll 10. The pressing mechanism 200 includes a pressing component 300 and an adjusting component 400. The adjusting component 400 is used to adjust the position of the pressing component 300 in a third direction. The pressing component 300 is used to seal the two ends of the packaging film 20 of the paper roll 10 along the second direction. The pressing component 300 can seal the packaging film 20 in various ways (e.g., heat sealing).

[0039] For details, please refer to Figure 2 and Figure 3 The pressing assembly 300 includes a mounting base 310 and at least two hot pressing components 320. Each hot pressing component 320 is disposed on the mounting base 310 and distributed on opposite sides of the conveying mechanism 100 along the second direction. The adjusting assembly 400 is connected to the mounting base 310 and is used to adjust the position of the mounting base 310 in the third direction.

[0040] It is understandable that since each hot-pressing component 320 is mounted on the mounting base 310, the position of each hot-pressing component 320 in the third-order direction can be adjusted by adjusting the position of the mounting base 310 in the third-order direction through the adjusting assembly 400.

[0041] The beneficial effects here are: the position of each hot pressing component 320 in the third direction can be adjusted by using the adjustment component 400. When some areas of each hot pressing component 320 are worn too much, the unworn areas can be used, thereby greatly improving the utilization efficiency of the pressing component 300 and extending the overall service life of the roll forming device.

[0042] In the embodiments of this application, the mounting base 310 is a component used to provide mounting space for each hot-pressing component 320, and the mounting base 310 can adopt various structural forms. For example, the mounting base 310 can be a single block structure, or it can be a base structure composed of multiple plates spliced ​​together.

[0043] In the embodiments of this application, each hot-pressing component 320 and the mounting base 310 are separate structures, and each hot-pressing component 320 and the mounting base 310 can be connected by means of snap-fit, plug-in, screw-in, etc. The structural shapes of each hot-pressing component 320 can be identical or different.

[0044] For more specific details, please refer to Figure 2 and Figure 3 Each hot pressing component 320 includes a pressing belt 321, a pressing drive component, a driving wheel 323, and a driven wheel 324. The driving wheel 323 and the driven wheel 324 are spaced apart along a first direction. The pressing belt 321 is sleeved on the driving wheel 323 and the driven wheel 324. The pressing belt 321 is equipped with a heating element and is used to heat seal the packaging film 20 of the paper roll 10. The pressing drive component is connected to the driving wheel 323 and the driven wheel 324 respectively. Under the drive of the pressing drive component, the driving wheel 323 and the driven wheel 324 rotate synchronously and drive the pressing belt 321 to rotate.

[0045] Understandably, driven by the pressing drive, the driving wheel 323 and the driven wheel 324 rotate synchronously and drive the pressing belt 321 to rotate, so that the pressing belt 321 contacts the packaging film 20 of the paper roll 10 in different areas along the first direction, so that the packaging film 20 of the paper roll 10 is heat-sealed by the pressing belt 321.

[0046] The beneficial effect here is that the pressing belt 321 contacts the packaging film 20 of the paper roll 10 in different areas along the first direction, so that the packaging film 20 of the paper roll 10 is heat-sealed by the pressing belt 321, which helps to improve the sealing efficiency and sealing effect of the packaging film 20 of the paper roll 10.

[0047] In the embodiments of this application, the pressing belt 321 is provided with a heating element, which can be a heating wire or other components capable of generating heat; the pressing belt 321 can be a belt or other conveyor belt.

[0048] In the embodiments of this application, the driving wheel 323 and the driven wheel 324 are spaced apart along a first direction, and the pressing belt 321 is sleeved on the driving wheel 323 and the driven wheel 324. The driving wheel 323 and the driven wheel 324 can be gears, and the pressing belt 321 has tooth grooves that mesh with the gears. The number of driving wheels 323 and driven wheels 324 is not limited to one, that is, the number of driving wheels 323 and driven wheels 324 can be at least two.

[0049] In the embodiments of this application, the pressing drive is connected to the driving wheel 323 and the driven wheel 324 respectively. The pressing drive can be a motor, a cylinder or other drive structure that can output power.

[0050] Please refer to Figure 3 and Figure 4 The pressing belt 321 has a first hot pressing region 321a and a second hot pressing region 321b arranged adjacent to each other in a third direction. The adjusting component 400 can adjust the position of the mounting base 310 in the third direction so that the packaging film 20 of the paper roll 10 abuts against the first hot pressing region 321a or the second hot pressing region 321b.

[0051] It should be noted that the pressing belt 321 has a lateral... Figure 3 and Figure 4 The first hot-pressing region 321a and the second hot-pressing region 321b are arranged adjacently in the Z direction. During initial use, the first hot-pressing region 321a of the pressing belt 321 contacts the packaging film 20 of the paper roll 10, and the pressing assembly 300 presses the packaging film 20 of the paper roll 10 along... Figure 3 and Figure 4 The two ends in the Y direction are sealed, and then the conveying mechanism 100 is used to transport them along the Y direction. Figure 3 and Figure 4 The X-direction output shows a paper roll 10 with the packaging film 20 already sealed. After a period of use, the wear of the pressing belt 321 and / or the sealing effect of the packaging film 20 of the paper roll 10 can be detected. If the pressing belt 321 is severely worn and / or the sealing effect of the packaging film 20 of the paper roll 10 is poor, the position of the pressing component 300 in the height direction can be adjusted by the adjusting component 400 so that the second hot pressing area 321b of the pressing component 300 contacts the packaging film 20 of the paper roll 10, so that the packaging film 20 of the paper roll 10 can be effectively sealed.

[0052] The beneficial effect here is that the pressing belt 321 has a first hot pressing area 321a and a second hot pressing area 321b arranged adjacent to each other in a third direction. When one of the hot pressing areas of the pressing belt 321 is worn too much, the other unworn area can be used, thereby greatly improving the utilization efficiency of the pressing assembly 300 and extending the overall service life of the roll forming device.

[0053] In the embodiments of this application, the heights of the first hot-pressing region 321a and the second hot-pressing region 321b in the third direction may be equal or unequal, depending on the actual requirements.

[0054] In the embodiments of this application, the number of the first hot-pressing region 321a and the second hot-pressing region 321b is not limited to one. When the number of the first hot-pressing region 321a and the second hot-pressing region 321b is at least two, the first hot-pressing region 321a and the second hot-pressing region 321b can be alternately distributed along a third direction, that is, arranged cyclically along a third direction according to the pattern of first hot-pressing region 321a, second hot-pressing region 321b, first hot-pressing region 321a, second hot-pressing region 321b.

[0055] For details, please refer to Figure 2 In the first direction, the length of the pressing belt 321 is less than or equal to the length of the conveying mechanism 100, and the length of the pressing belt 321 is greater than the length of the paper roll 10.

[0056] Understandably, in Figure 2 In the X direction shown, the length of the pressing belt 321 is greater than the length of the paper roll 10, and the length of the pressing belt 321 does not exceed the length of the conveying mechanism 100.

[0057] The beneficial effect here is that it can increase the contact area between the pressing belt 321 and the packaging film 20 of the paper roll 10 in the first direction, which is conducive to improving the sealing efficiency and sealing effect of the packaging film 20 of the paper roll 10.

[0058] Please refer to Figure 3 The adjustment assembly 400 includes an adjustment drive 410 and an adjustment screw 420. The mounting base 310 has a screw hole, the adjustment screw 420 passes through the screw hole and is threaded into the screw hole, and the adjustment drive 410 is connected to the adjustment screw 420. Under the drive of the adjustment drive 410, the adjustment screw 420 rotates and drives the mounting base 310 to move in a third direction.

[0059] It should be noted that, driven by the adjusting drive component 410, the adjusting screw 420 rotates and drives the mounting base 310 to move along the third direction, thereby adjusting the position of each hot pressing component 320 in the third direction.

[0060] The beneficial effects here are: rotating the adjusting screw 420 can adjust the position of each hot pressing component 320 in the third direction. When some areas of each hot pressing component 320 are worn too much, the unworn areas can be used, thereby greatly improving the utilization efficiency of the pressing assembly 300. The operation is convenient and the structural design is simple and reasonable.

[0061] In the embodiments of this application, the adjusting drive member 410 is a component connected to the adjusting lead screw 420 and used to drive the adjusting lead screw 420 to rotate. The adjusting drive member 410 may be a motor, a cylinder, or other drive structure capable of power output.

[0062] In the embodiments of this application, the adjusting screw 420 is a component that passes through and is threadedly engaged with the screw hole of the mounting base 310. The adjusting screw 420 has an external thread on its outer periphery, and the mounting base 310 has a screw hole. The adjusting screw 420 passes through the screw hole, and the external thread of the adjusting screw 420 is threadedly engaged with the screw hole. The number of screw holes and adjusting screws 420 is not limited to one. When the number of screw holes and adjusting screws 420 is at least two, the screw holes and adjusting screws 420 are arranged in a one-to-one correspondence.

[0063] Further, please refer to Figure 3 The pressing mechanism 200 also includes a controller and a detection component. The controller is electrically connected to the detection component and the adjustment drive component 410 respectively. The detection component is used to detect the wear of the pressing belt 321 and / or the sealing effect of the packaging film 20 of the paper roll 10. The controller controls the operation of the adjustment drive component 410 according to the detection results of the detection component.

[0064] Understandably, the detection device is used to detect the wear of the pressing belt 321 and / or the sealing effect of the packaging film 20 of the paper roll 10. When the pressing belt 321 is severely worn and / or the sealing effect of the packaging film 20 of the paper roll 10 is poor, the controller controls the operation of the adjustment drive 410 to adjust the position of each hot pressing component 320 in the height direction, so that other areas of each hot pressing component 320 contact the packaging film 20 of the paper roll 10, so that the packaging film 20 of the paper roll 10 can be effectively sealed.

[0065] The beneficial effect here is that when some areas of each hot-pressing component 320 are worn excessively, the unworn areas can be utilized, thereby greatly improving the utilization efficiency of the pressing assembly 300. The operation is convenient and the structural design is simple and reasonable.

[0066] In embodiments of this application, the detection component is a member used to detect the wear of the pressing belt 321 and / or the sealing effect of the packaging film 20 of the paper roll 10. The detection component can be at least one of laser detection, infrared detection, X-ray detection, and visual alignment inspection.

[0067] Furthermore, please refer to Figure 3 The pressing assembly 300 also includes a translation drive 330, which is connected to each hot press 320 and is used to drive each hot press 320 to move along the second direction in order to adjust the position of each hot press 320 in the second direction.

[0068] Understandably, under the drive of the translation drive 330, each hot pressing component 320 can move along the second direction to change its position in the second direction.

[0069] The beneficial effect here is that the position of each hot pressing component 320 in the second direction can be adjusted so that each hot pressing component 320 can be adapted to paper rolls 10 of different sizes or models, thus expanding the applicability of the pressing assembly 300.

[0070] In the embodiments of this application, the translation drive 330 is a component connected to each hot-pressing component 320 and used to drive each hot-pressing component 320 to move along a second direction. The translation drive 330 may be a motor, a cylinder, or other drive structure capable of power output.

[0071] Please refer to Figure 2 The conveying mechanism 100 includes at least two conveyor belts 110, each conveyor belt 110 extending along a first direction and arranged side by side along a second direction.

[0072] It should be noted that each conveyor belt 110 along Figure 2 As shown, it extends in the X direction, and each conveyor belt 110 extends along... Figure 1 The figures are arranged side-by-side along the Y direction.

[0073] The beneficial effect here is that each conveyor belt 110 extends along the first direction and is arranged side by side along the second direction, which facilitates the support of the paper roll 10 before packaging and the conveying of the paper roll 10 after packaging. The structural design is simple and reasonable.

[0074] In the embodiments of this application, the lengths of each conveyor belt 110 in the first direction may be equal or unequal; the conveyor belts 110 in the second direction may be equally spaced side by side or non-equally spaced side by side. Each conveyor belt 110 may be a belt or other type of conveyor belt.

[0075] Please refer to Figure 1 In one embodiment, the packaging machine includes the roll forming device described above.

[0076] It should be noted that the packaging machine also includes a receiving device, which is located downstream of the roll forming device and is used to receive the paper roll 10 output by the roll forming device.

[0077] The aforementioned packaging machine is capable of sealing the packaging film 20 of the paper roll 10 and conveying the paper roll 10. When the pressing belt 321 is severely worn and / or the sealing effect of the packaging film 20 of the paper roll 10 is poor, the position of the pressing component 300 in the height direction can be adjusted by the adjusting component 400 so that other areas of the pressing component 300 contact the packaging film 20 of the paper roll 10, so that the packaging film 20 of the paper roll 10 can be effectively sealed. When some areas of the pressing component 300 are worn too much, the unworn areas can be used, thereby greatly improving the utilization efficiency of the pressing component 300 and extending the overall service life of the roll forming device.

[0078] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0079] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
