[0001] The present invention relates to the technical field of feeding machines, and specifically to a feeding device and an operation method for bubble film processing. Background Art

[0002] During the processing of bubble film, the feeding device plays a crucial role. Traditional feeding devices often adopt simple conveyor belt or roller structures, and achieve continuous feeding of bubble film through mechanical drive. However, when these traditional devices feed bubble film, there are often problems such as insufficient friction, unstable feeding, and inconvenient adjustment, resulting in phenomena such as deviation and jamming of the bubble film during feeding, which affect the processing efficiency and quality.

[0003] To solve these problems, some improved feeding devices for bubble film processing have emerged on the market.

[0017] An operating method of a feeding device for processing bubble film, the method comprising the following steps:

[0018] Step 1. Initial installation and adjustment

[0019] Step 1.1: Fix the mounting frame: Overlap the mounting base at the bottom of the mounting frame on the frame of the bubble film cutting machine, or place the mounting frame at the desired location according to the usage scenario. Use bolts to pass through the bolt holes on the mounting base and then tighten them to fix the mounting frame at the specified location.

[0020] Step 1.2: Adjust the support structure: If the feeding device needs to be supported independently on the ground, screw the second hand screw to remove it from the screw hole, then move the pad to pull the sleeve plate through the extension support plate to drive the sleeve to rotate downward 90 degrees with the limit axis as the center axis. Screw the second hand screw back into the screw hole to limit the sleeve plate. Adjust the distance that the extension support plate extends out of the sleeve plate as needed, then loosen the first hand screw, pull the extension support plate along the sleeve plate to the appropriate position, and finally screw the first hand screw back to clamp the rubber gasket to brake the extension support plate. Use bolts to pass through the second bolt hole on the pad and fix it to the ground to ensure that the mounting frame is stable and does not tip over.

[0021] Step 2. Switching the roller function

[0022] Step 2.1: Switch to the conveyor roller: Pinch the screw handle and turn it counterclockwise. The screw rod rotates with the screw handle, and the screw rod moves along the threaded sleeve. The bottom plate of the extension frame moves along the slot to the outside of the slot until the assembly block is pulled out of the assembly slot. At this time, the bubble film can pass through the two rollers and be pulled forward by the winding device. The two rollers act as conveyor rollers.

[0023] Step 2.2: Switch to driving roller: Twist the screw handle back to drive the bottom plate of the extension frame to move back along the slot until the assembly block is inserted into the assembly slot. Trigger the switch of the servo motor, and the servo motor drives the assembly block to rotate, thereby driving the corresponding roller to rotate. Make sure that the two servo motors rotate in opposite directions so that the bubble film is driven forward by the two rollers.

[0024] Step 3. Installation and disassembly of the anti-slip rubber sleeve

[0025] Step 3.1: Install the anti-slip rubber sleeve: When the roller body acts as a driving roller, unfold the two anti-slip rubber sleeves and sleeved them on the roller body. Push the rubber rings at the ends of the two anti-slip rubber sleeves into the first clamping groove on the surface of the roller body to realize the limit of the anti-slip rubber sleeve.

[0026] Step 3.2: Disassemble the anti-slip rubber sleeve: When the roller body acts as a conveyor roller, pull out the rubber ring from the first clamping groove. Turn the anti-slip rubber sleeve outward and roll it up with the rubber ring as the inner core. Then, insert the rolled-up anti-slip rubber sleeve into the two elastic plastic limiting strips for limiting.

[0027] Step 4. Limitation and unlocking of the extension frame

[0028] Step 4.1: Unlock the extension frame: Before the adjustment assembly block is pulled out of the assembly groove, pinch the pull rod with your hand and张拉 the insertion block to move downward. The insertion block is pulled out of the positioning slot. At this time, the elastic band is stretched and deformed, and the limitation between the extension frame and the slot is cancelled.

[0029] Step 4.2: Limit the extension frame: After the bottom plate of the extension frame is inserted into the slot (i.e., after the assembly block is inserted into the assembly groove), the elastic band supports the insertion block and inserts it into the positioning slot to limit from below the bottom plate of the extension frame to prevent the extension frame from moving.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] The feeding device and operation method for bubble film processing proposed by the present invention have the beneficial effects of simple structure, convenient adjustment, stable conveying, reliable limitation, flexible support and low maintenance cost. It can meet the conveying requirements during the bubble film processing, improve the processing efficiency and quality; by adopting the mounting frame with a "C"-shaped plate structure and the pluggable extension frame, the simplification of the structure and the convenience of adjustment are realized. Users can easily adjust the position of the extension frame according to needs, thereby changing the driving or conveying state of the roller body; the mounting seat and sleeve structure at the bottom of the mounting frame enable the entire device to be flexibly fixed on the frame of the bubble film cutting machine or used as an independent conveying structure. At the same time, by adjusting the extension distance and angle of the extension support plate, different usage environments and requirements can be adapted. Brief Description of the Drawings

DETAILED DESCRIPTION

[0049] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the 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.

[0050] For example, see Figures 1 to 16, the present invention provides a technical solution: a feeding device for bubble film processing, including a mounting frame 1. The mounting frame 1 is in a "C"-shaped plate structure. Between two parallel side plates of the mounting frame 1, two roller bodies 4 are rotatably connected. On both of the two parallel side plates of the mounting frame 1, two mounting openings 2 are provided. The two mounting openings 2 are arranged vertically. Inside the mounting opening 2, a bearing 3 is fixed. The shaft end of the roller body 4 is inserted into the inner ring of the bearing 3. On one side plate of the mounting frame 1, an extension frame 6 is inserted. On the surface of the extension frame 6, a servo motor 7 is installed. The shaft body of the servo motor 7 penetrates through the extension frame 6 and then a splicing block 8 is fixed. On one end of the mounting frame 1, a splicing groove 9 is provided. The splicing block 8 and the splicing groove 9 are matched. When the splicing block 8 is inserted into the splicing groove 9, the roller body 4 acts as a driving roller. After the splicing block 8 is withdrawn from the splicing groove 9, the roller body 4 acts as a conveying roller; the extension frame 6 is in an "L"-shaped plate structure. The bottom plate of the extension frame 6 is inserted into a slot 5. The slot 5 is opened on one side of the bottom plate of the mounting frame 1. On one side plate of the mounting frame 1, two stop bars 42 are fixed. The extension frame 6 is located between the two stop bars 42. The splicing block 8 is a square block, and the splicing groove 9 is a square groove. The plate length of the splicing block 8 is less than the width of the bottom plate of the extension frame 6; on one side of the bottom plate of the extension frame 6, a reserved groove 10 is provided. Inside the reserved groove 10, a screwed sleeve 11 is inserted. One end of the screwed sleeve 11 is fixed on the surface of the slot 5. On the surface of the extension frame 6, a limit opening 12 is provided. The limit opening 12 is an "I"-shaped circular opening. Inside the limit opening 12, a turning handle 13 is rotatably connected. The turning handle 13 is an "I"-shaped round rod. One end of the turning handle 13 is fixed with a screwing handle 14. The screwing handle 14 is a "cross"-shaped plate. The other end of the turning handle 13 is fixed with a screw rod 15. The screw rod 15 is inserted into and screwed in the screwed sleeve 11.

[0051] During use, when the driving of the two roller bodies 4 is cancelled and they act as conveying rollers, pinch the screwing handle 14 and rotate the turning handle 13 counterclockwise. The turning handle 13 drives the screw rod 15 to rotate, and the screw rod 15 moves along the screwed sleeve 11. At this time, the bottom plate of the extension frame 6 moves along the slot 5 to the outside of the slot 5 until the splicing block 8 is withdrawn from the splicing groove 9. At this time, when the bubble film passes through the two roller bodies 4 and the end of the bubble film is pulled by the winding device, the two roller bodies 4 play a role in conveying the bubble film; when it is necessary to drive the roller body 4, turn back the screwing handle 14 to drive the bottom plate of the extension frame 6 to move back along the slot 5 until the splicing block 8 is inserted into the splicing groove 9. At this time, after triggering the switch of the servo motor 7, when the servo motor 7 drives the splicing block 8 to rotate, the splicing block 8 drives the corresponding roller body 4 to rotate. It should be noted that the rotation directions of the two servo motors 7 are opposite. In this way, after the bubble film passes through the two roller bodies 4, it is driven forward by the two roller bodies 4 to realize the conveying of the bubble film.

[0052] When in use, in order to limit the extension frame 6 that is adjusted to the assembly block 8 being pulled out of the assembly groove 9, an installation opening 16 is opened on the bottom plate of the installation frame 1, and the installation opening 16 is connected to the reserved groove 10. An insertion block 17 is inserted inside the installation opening 16, and one end of the insertion block 17 is inserted in the positioning slot 18. The positioning slot 18 is opened on the bottom surface of the extension frame 6. One end of the insertion block 17 is provided with an inclined surface, and the inclined surface faces the turning handle 13. A notch 21 is opened at the other end of the insertion block 17, and a pull rod 22 is fixed between two parallel side walls of the notch 21. A through hole 19 is opened on the surface of the insertion block 17, and an elastic band 20 is inserted inside the through hole 19. The two ends of the elastic band 20 are respectively fixed on the two parallel side walls of the installation opening 16. When the elastic band 20 is in the initial state, the elastic band 20 supports the insertion of the insertion block 17 into the positioning slot 18.

[0053] During use, when adjusting the extension frame 6 away from the mounting frame 1, that is, before adjusting the assembling block 8 to be pulled out of the assembling slot 9, the pull rod 22 is pinched by hand to tension the plug block 17 to move downward. After the plug block 17 is pulled out of the positioning slot 18, the elastic band 20 is tensioned and deformed, and the limit between the extension frame 6 and the slot 5 is cancelled. Then the screw handle 14 is turned to adjust the position of the extension frame 6. The reason for adding the plug block 17 is to limit the bottom plate of the extension frame 6 after the bottom plate of the extension frame 6 is inserted into the slot 5, that is, after the assembling block 8 is inserted into the assembling slot 9, to prevent the extension frame 6 from moving, thereby ensuring that the assembling block 8 is always inserted in the assembling slot 9, and ensuring that the servo motor 7 can drive the corresponding roller body 4 to rotate.

[0054] In order to increase the friction between the roller body 4 and the bubble film when the two roller bodies 4 are filled to the driving roller, an anti-skid rubber sleeve 23 is fixed on the end of the roller body 4, and a rubber ring 24 is fixed on one end of the anti-skid rubber sleeve 23. After the anti-skid rubber sleeve 23 is unfolded and sleeved on the roller body 4, the rubber ring 24 is sleeved in a slot 25, and the slot 25 is opened on the surface of the roller body 4; the slot 25 is an annular groove with a circular fracture, and the slot 25 is centered on the shaft of the roller body 4. The rubber ring 24 is an annular strip with a semicircular cross section. The rubber rings 24 at the ends of the two anti-skid rubber sleeves 23 are pushed into the slot 25, and two elastic plastic limit strips 26 are fixed at both ends of the roller body 4. The elastic plastic limit strip 26 is an arc strip with a "J"-shaped cross section.

[0055] When in use, when the roller body 4 acts as a driving roller, the two anti-skid rubber sleeves 23 are unfolded and sleeved on the roller body 4, and the rubber rings 24 at the ends of the two anti-skid rubber sleeves 23 are pushed into the card slot 1 25 to limit the two anti-skid rubber sleeves 23 and ensure that the joints of the two anti-skid rubber sleeves 23 after unfolding are flat. The anti-skid rubber sleeves 23 increase the friction between the roller body 4 and the bubble film, thereby ensuring that the bubble film moves when the roller body 4 rotates; when the drive of the two roller bodies 4 is withdrawn, that is, the assembling block 8 is pulled out of the assembling groove 9, the two roller bodies 4 act as conveying rollers. It is necessary to remove the anti-skid rubber sleeves 23 from the surface of the roller body 4 to reduce the friction between the roller body 4 and the bubble film. After the rubber ring 24 is pulled out from the card slot 1 25, the anti-skid rubber sleeve 23 is turned outward and rolled up with the inner core of the rubber ring 24 turned outward, and the rolled anti-skid rubber sleeve 23 is inserted into the two elastic plastic limit strips 26 for limiting the position.

[0056] Two mounting seats 27 are fixed on the bottom surface of the mounting frame 1. A sleeve 31 is rotatably connected to the bottom plate of the mounting seat 27. A hand screw 36 is provided on the surface of the mounting seat 27 for braking the sleeve 31. A sleeve plate 32 is fixed on the surface of the sleeve 31. An extension support plate 33 is inserted at the bottom end of the sleeve plate 32. A pad 34 is fixed at the bottom end of the extension support plate 33. After the extension support plate 33 is retracted into the sleeve plate 32, the sleeve plate 32 is placed flat on the bottom surface of the mounting frame 1; the mounting seat 27 is in an "L" shape. The mounting seat 27 has a plate-shaped structure, and a plurality of bolt holes 28 are provided on the bottom surface of the mounting seat 27. A mounting groove 29 is provided on one side of the mounting seat 27. The width of the mounting groove 29 is smaller than the width of the mounting seat 27. A limit axis 30 is fixed between two parallel side walls of the mounting groove 29. A sleeve 31 is sleeved on the rod body of the limit axis 30. Two groups of screw holes 37 are provided on the surface of the sleeve 31. The two groups of screw holes 37 are vertically distributed, and each group of screw holes 37 has a plurality of screw holes. The mounting seat 27 The vertical plate of the sleeve 32 is screwed with a hand screw 36, and the hand screw 36 corresponds to the screw hole 37. The hand screw 36 passes through the vertical plate of the mounting seat 27 and is screwed in the screw hole 37; the sleeve plate 32 is a square frame structure, the pad 34 is an "L"-shaped plate structure, and rubber gaskets 35 are fixed on both sides of the extended support plate 33. The plate length of the rubber gasket 35 is equal to the plate length of the extended support plate 33. The sleeve plate 32 has a hand screw 38 screwed on both sides of the notch, and the hand screw 38 is screwed on both sides of the notch. The side plate that passes through the sleeve plate 32 is clamped to extend the support plate 33; the surface of the pad plate 34 is provided with a second card groove 40, and the second card groove 40 is an arc-shaped groove. The surface of the second card groove 40 is provided with a plurality of bolt holes 39. The bottom surface of the mounting frame 1 is provided with a bottom groove 43, and rubber strips 41 are fixed on two parallel side walls of the bottom groove 43. When the sleeve plate 32 is placed flat on the bottom surface of the mounting frame 1, one end of the pad plate 34 is inserted into the bottom groove 43, and the rubber strip 41 is inserted into the second card groove 40.

[0057] During use, when it is necessary to fix the mounting frame 1 on the frame of the bubble film cutting machine, the sleeve plate 32 is placed flat under the mounting frame 1. At this time, one end of the pad 34 extends into the bottom groove 43, and the rubber strip 41 is inserted into the card slot 2 40 to achieve temporary limiting of the baffle 42; then the mounting frame 1 and the mounting seat 27 at the bottom of the mounting frame 1 are overlapped on the frame of the bubble film cutting machine, and the bolts are passed through the bolt hole 1 28 and then locked to fix the mounting seat 27 on the frame of the bubble film cutting machine.

[0058] When the mounting bracket 1 is installed between the bubble film cutting machine and the winding equipment, or when the mounting bracket 1 is installed between two bubble film processing equipment to serve as a conveying structure, after the hand screw 2 38 is screwed out of the screw hole 37, the pad 34 is moved to pull the sleeve plate 32 through the extension support plate 33 to drive the sleeve tube 31 to rotate downward ninety degrees with the limit axis 30 as the center axis. At this time, the sleeve plate 32 and the mounting bracket 1 are perpendicular, and the hand screw 2 38 is screwed into the screw hole 37 to limit the sleeve plate 32. Then, the distance that the extension support plate 33 extends out of the sleeve plate 32 is adjusted as needed, that is, after loosening the hand screw 1 36, the extension support plate 33 is pulled out and moved along the sleeve plate 32, and the hand screw 1 36 is screwed back to clamp the rubber gasket 35 to brake the extension support plate 33. At this time, the pad 34 contacts the ground, and the bolt is fixed to the ground after passing through the bolt hole 2 39. At this time, the pad 34 is fixed to the ground to prevent the mounting bracket 1 from tipping over.

[0059] Embodiment 2, based on embodiment 1, proposes an operation method of a feeding device for bubble film processing, the method comprising the following steps:

[0060] Step 1. Initial installation and adjustment

[0061] Step 1.1: Fix the mounting frame: overlap the mounting base 27 at the bottom of the mounting frame 1 on the frame of the bubble film cutting machine, or place the mounting frame 1 at the desired position according to the usage scenario. Use bolts to pass through the bolt holes 28 on the mounting base 27 and tighten them to fix the mounting frame 1 at the specified position.

[0062] Step 1.2: Adjust the support structure: If the feeding device needs to be supported independently on the ground, screw the second hand screw 38 to remove it from the screw hole 37, and then move the pad 34 to pull the sleeve 32 through the extension support plate 33 to drive the sleeve 31 to rotate downward ninety degrees with the limiting axis 30 as the center axis. Re-tighten the second hand screw 38 and screw it into the screw hole 37 to limit the sleeve 32. Adjust the distance that the extension support plate 33 extends out of the sleeve 32 as needed, then loosen the hand screw 1 36, pull the extension support plate 33 along the sleeve 32 to a suitable position, and finally re-tighten the hand screw 1 36 to clamp the rubber gasket 35 to brake the extension support plate 33. Use bolts to pass through the second bolt hole 39 on the pad 34 and fix it to the ground to ensure that the mounting frame 1 is stable and does not fall over.

[0063] Step 2. Switching the roller function

[0064] Step 2.1: Switch to the conveying roller: Pinch the screw handle 14 and turn the handle 13 counterclockwise, the handle 13 drives the screw 15 to rotate, and the screw 15 moves along the threaded sleeve 11. The bottom plate of the extension frame 6 moves along the slot 5 to the outside of the slot 5 until the assembly block 8 is pulled out of the assembly slot 9. At this time, the bubble film can pass through the two rollers 4 and be pulled forward by the winding device, and the two rollers 4 act as conveying rollers.

[0065] Step 2.2: Switch to driving roller: Twist the screw handle 14 back to drive the bottom plate of the extension frame 6 to move back along the slot 5 until the assembly block 8 is inserted into the assembly slot 9. Trigger the switch of the servo motor 7, which drives the assembly block 8 to rotate, thereby driving the corresponding roller body 4 to rotate. Make sure that the two servo motors 7 rotate in opposite directions so that the bubble film is driven forward by the two roller bodies 4.

[0066] Step 3. Installation and removal of anti-slip rubber sleeve

[0067] Step 3.1: Install the anti-skid rubber sleeve: When the roller body 4 acts as a driving roller, unfold the two anti-skid rubber sleeves 23 and sleeve them on the roller body 4. Push the rubber rings 24 at the ends of the two anti-skid rubber sleeves 23 into the groove 1 25 on the surface of the roller body 4 to limit the anti-skid rubber sleeves 23.

[0068] Step 3.2: Disassemble the anti-skid rubber sleeve: When the roller body 4 acts as a conveying roller, pull the rubber ring 24 out of the card slot 1 25. Turn the anti-skid rubber sleeve 23 outward and roll it outward with the rubber ring 24 as the inner core, and insert the rolled anti-skid rubber sleeve 23 into two elastic plastic limit strips 26 for limiting the position.

[0069] Step 4. Limit and unlock the extension bracket

[0070] Step 4.1: Unlock the extension frame: Before adjusting the assembly block 8 to be pulled out of the assembly slot 9, manually squeeze the pull rod 22 to pull the plug block 17 downward, and the plug block 17 is pulled out of the positioning slot 18. At this time, the elastic band 20 is stretched and deformed, and the limit between the extension frame 6 and the slot 5 is cancelled.

[0071] Step 4.2: Limiting the extension frame: After the base plate of the extension frame 6 is inserted into the slot 5 (i.e., the assembly block 8 is inserted into the assembly slot 9), the elastic band 20 supports the plug block 17 to be inserted into the positioning slot 18, and limits the extension frame 6 from the bottom of the base plate to prevent the extension frame 6 from moving.
