Description

Technical Field

[0001] The utility model relates to the technical field of bubble film forming devices, in particular to a bubble film forming device. Background Art

[0002] Bubble film is a product made of high-pressure polyethylene as the main raw material, with whitening agent, opening agent and other auxiliary materials added, and then extruded at a high temperature of about 230 degrees to form bubbles. It is a new type of plastic packaging material with light texture, good transparency, non-toxic and tasteless, which can prevent moisture, cushion and keep warm for products. The bubble film machine uses a through hole on the drum and applies negative pressure to the inside of the drum to generate negative pressure at the through hole position, and then the film on the drum can be sucked into the through hole, forming bubbles and finally becoming a bubble film; however, the simple use of negative pressure adsorption leads to insufficient gas inside the bubble and poor cushioning effect;

[0003] In the prior art, for example, announcement number CN220180118U proposes a bubble film machine. The present technical solution discloses a bubble film machine, including a forming roller and an auxiliary roller arranged side by side, wherein the forming roller is inserted with an air inlet pipe along the central axis, and a negative pressure fan is installed at the other end of the air inlet pipe, and an exhaust pipe is provided at the other end of the negative pressure fan, and the other end of the exhaust pipe extends to above the position between the forming roller and the auxiliary roller, and an air outlet assembly is installed below one end of the exhaust pipe located above the forming roller and the auxiliary roller. In the present utility model, the air extracted by the negative pressure fan can reach the position of the air outlet assembly through the exhaust pipe, and then reach between the bubble film and the bottom film, and then positive pressure can be inflated to the bubble position of the bubble film and the bottom film, so that the bubble is fuller and the buffering effect is better; the baffle of the present utility model is close to the position between the forming roller and the auxiliary roller, and then the gas discharged from the exhaust horn can be blocked as much as possible from being discharged from between the forming roller and the auxiliary roller, and then the gas can be ensured to enter the bubble as much as possible;

[0004] However, the existing bubble film machine cannot synchronously rewind the bubble film during operation, so that after the device completes the production and processing of the bubble film, the staff still needs to manually rewind the bubble film, thereby increasing the workload of the staff;

[0005] In order to solve the above problems, a bubble film forming device is proposed in the present application. Utility Model Content

[0006] The utility model aims to provide a bubble film forming device, which is mainly used to solve the problem that the existing bubble film machine cannot synchronously roll up the bubble film during operation, and the staff needs to manually roll up the bubble film, thereby increasing the workload of the staff.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A bubble film forming device includes a base and a forming roller. One side of the top of the base is fixedly connected with a fixed seat. The top of the fixed seat is slidably connected with symmetric clamping plates. One side of the two clamping plates facing each other is rotatably connected with a turntable. The center of the side of the turntable away from the clamping plate is fixedly connected with a positioning column. One side of the turntable close to the positioning column is fixedly connected with a rubber pad. One of the clamping plates is fixedly connected with a driving component on the side away from the turntable. A cavity is formed inside the fixed seat. One end of the inner wall of the cavity is rotatably connected with a bidirectional lead screw. The other end of the bidirectional lead screw extends out of the fixed seat and is rotatably connected with the fixed seat. The end of the bidirectional lead screw extending out of the fixed seat is fixedly connected with a rotating plate. One side of the rotating plate away from the bidirectional lead screw is rotatably connected with a handle. A limiting component is arranged on the rotating plate. The outer wall of the bidirectional lead screw is threadedly connected with symmetric threaded sleeves. The top of the threaded sleeve extends out of the fixed seat and is fixedly connected with the clamping plate, and the threaded sleeve is slidably connected with the fixed seat.

[0009] The working principle and beneficial effects of the present utility model:

[0010] 1. Working principle: When the device is in use, place the reel for winding the bubble film between the two clamping plates. Rotating the handle can drive the bidirectional lead screw to rotate through the rotating plate. While the bidirectional lead screw rotates, the two threaded sleeves threadedly connected with it can drive the two clamping plates on the fixed seat to approach each other and clamp the reel, thus playing a good fixing role for the reel. Then start the device to produce the bubble film. At the same time, the driving component operates, and the reel between the two clamping plates can be rotated, so as to realize the winding of the bubble film. After the bubble film winding is completed, reverse-rotating the handle can make the two clamping plates move away from the reel, thus facilitating people to take down the reel wound with the bubble film.

[0011] 2. Beneficial effects: After placing the reel between the two clamping plates, rotating the handle can make the two clamping plates approach each other and clamp the reel. Through the limiting component arranged on the rotating plate, a good fixing effect can be achieved on the rotating plate, thus effectively preventing the reel from loosening during the operation of the device. When starting the device to produce the bubble film, at the same time, the driving component operates to make the reel between the two clamping plates rotate synchronously, so as to realize the winding of the bubble film. The advantage of this setting is that it does not require manual winding of the bubble film when the device is in use, thus making the device more practical.

[0012] Preferably, the driving component includes an installation box fixedly connected to one side of one of the clamping plates away from the turntable. A motor is fixedly installed inside the installation box. The output end of the motor is fixedly connected with a rotating rod. The other end of the rotating rod penetrates through the clamping plate and is fixedly connected with the turntable, and the rotating rod is rotatably connected with the clamping plate. After fixing the reel for winding the bubble film between the two clamping plates, start the device to produce the bubble film. At the same time, start the motor inside the installation box, and the reel between the two clamping plates can be rotated synchronously to realize the winding of the bubble film.

[0013] Preferably, the limiting component includes a sliding rod penetrating through the rotating plate, and the sliding rod is slidably connected to the rotating plate. One end of the sliding rod is fixedly connected to a knob, and the other end is fixedly connected to a threaded rod. A plurality of threaded grooves matching the threaded rod are formed in the rotating plate, and the threaded grooves are linearly and equally spaced on one side of the rotating plate. Place the reel between the two clamping plates, rotate the handle to make the two clamping plates approach each other and clamp the reel, then push the knob to make the sliding rod drive the threaded rod to slide into the threaded groove. After the threaded rod enters the threaded groove, rotate the knob to thread the threaded rod with the inner wall of the threaded groove. Tightening the knob can play a good role in fixing the rotating plate, thus effectively preventing the reel from loosening during the operation of the device.

[0014] Preferably, a plurality of rolling balls are rotatably connected to the bottom of the clamping plate, and the rolling balls are linearly and equally spaced on the clamping plate. When the clamping plate slides on the fixed seat, through the plurality of rolling balls arranged at the bottom of the clamping plate, the friction between the clamping plate and the fixed seat can be effectively reduced, so that it is easier and more labor-saving for people to rotate the handle when the clamping plate slides.

[0015] Preferably, a plurality of ventilation holes are formed on both sides of the installation box, and filter nets are fixedly connected to the inner walls of the ventilation holes. During the operation of the device, the motor inside the installation box will generate a certain amount of heat. Through the ventilation holes formed on both sides of the installation box, a good heat dissipation effect can be achieved on the motor inside the installation box. Through the filter nets arranged on the inner walls of the ventilation holes, it can effectively prevent external dust from entering the installation box and affecting the normal operation of the motor, thus effectively ensuring the normal operation of the device.

[0016] Preferably, the corners at the openings of the threaded grooves are all chamfered. By chamfering the corners at the openings of the threaded grooves, it is more convenient for the threaded rod to be inserted into the slot, thus making the use of the device more convenient.

[0017] Preferably, a rubber sleeve is sleeved on the outer wall of the handle, and anti-slip lines are formed on the outer wall of the rubber sleeve. Through the rubber sleeve sleeved on the outer wall of the handle, it can make the hand of the staff more comfortable when holding and rotating the handle. Through the anti-slip lines formed on the outer wall of the rubber sleeve, the friction between the hand of the staff and the handle can be increased, thus effectively preventing the hand from slipping when people rotate the handle.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4, a bubble film forming device, comprising a base 1 and a forming roller 2. One side of the top of the base 1 is fixedly connected with a fixed seat 3. The top of the fixed seat 3 is slidably connected with symmetrical clamping plates 4. Both opposite sides of the two clamping plates 4 are rotatably connected with turntables 5. The center of the side of the turntable 5 away from the clamping plate 4 is fixedly connected with a positioning column 7. Place the reel for winding the bubble film between the two clamping plates 4. The two clamping plates 4 can be clamped together to clamp the reel. One side of the turntable 5 close to the positioning column 7 is fixedly connected with a rubber pad 6, which can play a better fixing role for the reel. Moreover, because the rubber material is relatively soft, it can play a better protective effect on the reel. The bottom of the clamping plate 4 is rotatably connected with a plurality of balls 20, and the balls 20 are linearly arranged at equal intervals on the clamping plate 4, which can effectively reduce the friction between the clamping plate 4 and the fixed seat 3, so that the clamping plate 4 slides more smoothly on the fixed seat 3. One of the clamping plates 4 is fixedly connected with a driving component on the side away from the turntable 5. During the operation of the device, the reel between the two clamping plates 4 is synchronously rotated through the operation of the driving component, and the winding of the bubble film can be realized. A cavity 8 is opened inside the fixed seat 3. One end of the inner wall of the cavity 8 is rotatably connected with a bidirectional lead screw 9. The other end of the bidirectional lead screw 9 extends out of the fixed seat 3 and is rotatably connected with the fixed seat 3. The end of the bidirectional lead screw 9 extending out of the fixed seat 3 is fixedly connected with a turning plate 10. The side of the turning plate 10 away from the bidirectional lead screw 9 is rotatably connected with a handle 11. The outer wall of the bidirectional lead screw 9 is threadedly connected with symmetrical thread sleeves 12. The top of the thread sleeve 12 extends out of the fixed seat 3 and is fixedly connected with the clamping plate 4, and the thread sleeve 12 is slidably connected with the fixed seat 3. Rotating the handle 11 can drive the bidirectional lead screw 9 to rotate through the turning plate 10. While the bidirectional lead screw 9 rotates, the two thread sleeves 12 threadedly connected with it can drive the two clamping plates 4 on the fixed seat 3 to approach each other and clamp the reel, and then a good fixing effect can be achieved on the reel. A rubber sleeve is sleeved on the outer wall of the handle 11, which can make the hand of the staff more comfortable when holding and rotating the handle 11. Anti-slip lines are provided on the outer wall of the rubber sleeve, which can increase the friction between the hand of the staff and the handle 11, so as to effectively prevent the hand from slipping when people rotate the handle 11. A limiting component is arranged on the turning plate 10, which can play a good fixing role for the turning plate 10, so as to effectively prevent the reel from loosening during the operation of the device.

[0025] Such as Figure 2As shown in the figure, one side of the driving component where one clamping plate 4 is away from the turntable 5 is fixedly connected with a mounting box 13. A motor 14 is fixedly installed inside the mounting box 13. A plurality of ventilation holes 21 are opened on both sides of the mounting box 13. The motor 14 inside the mounting box 13 will generate a certain amount of heat. Through the ventilation holes 21 opened on both sides of the mounting box 13, it can play a good heat dissipation effect on the motor 14 inside the mounting box 13. The inner walls of the ventilation holes 21 are fixedly connected with filter nets, which can effectively prevent external dust from entering the inside of the mounting box 13 and affecting the normal operation of the motor 14, thereby effectively ensuring the normal operation of the device. The output end of the motor 14 is fixedly connected with a rotating rod 15. The other end of the rotating rod 15 penetrates through the clamping plate 4 and is fixedly connected with the turntable 5, and the rotating rod 15 is rotatably connected with the clamping plate 4. After fixing the reel for winding the bubble film between the two clamping plates 4, starting the device can produce bubble film. At the same time, starting the motor 14 inside the mounting box 13 can make the reel between the two clamping plates 4 rotate synchronously, realizing the winding of the bubble film.

[0026] As Figure 2 and Figure 4 As shown in the figure, the limiting component includes a slide rod 16 penetrating through a rotating plate 10, and the slide rod 16 is slidably connected with the rotating plate 10. One end of the slide rod 16 is fixedly connected with a knob 17, and the other end is fixedly connected with a threaded rod 18. A plurality of threaded grooves 19 matching the threaded rod 18 are opened on the rotating plate 10, and the threaded grooves 19 are linearly arrayed and equidistantly distributed on one side of the rotating plate 10. The corners at the openings of the threaded grooves 19 are chamfered. After placing the reel between the two clamping plates 4 and rotating the handle 11 to make the two clamping plates 4 approach each other and clamp the reel, push the knob 17 to make the slide rod 16 drive the threaded rod 18 to slide into the threaded groove 19. After the threaded rod 18 enters the threaded groove 19, rotate the knob 17 to make the threaded rod 18 threadedly connected with the inner wall of the threaded groove 19. After tightening the knob 17, it can play a good fixing role on the rotating plate 10, thereby effectively preventing the reel from loosening during the operation of the device.

[0027] The motors 14 are all electrically connected to a controller, and the controller can send an electrical signal to the motors 14 to control the start of the motors 14.

[0028] As can be seen from the above, the specific implementation manner of the present invention is as follows:

[0029] When the device is in use, place the reel for winding the bubble film between the two clamping plates 4. Rotating the handle 11 can drive the bidirectional lead screw 9 to rotate through the rotating plate 10. While the bidirectional lead screw 9 is rotating, the two threaded sleeves 12 threadedly connected to it can drive the two clamping plates 4 on the fixed seat 3 to approach each other and clamp the reel. Then, push the knob 17 to make the sliding rod 16 drive the threaded rod 18 to slide into the threaded groove 19. After the threaded rod 18 enters the threaded groove 19, rotate the knob 17 to threadedly connect the threaded rod 18 with the inner wall of the threaded groove 19. After tightening the knob 17, it can play a good role in fixing the rotating plate 10, thus effectively preventing the reel from loosening during the operation of the device. At this time, start the device to produce bubble film. At the same time, start the motor 14 inside the installation box 13, and the reel between the two clamping plates 4 can rotate synchronously to realize the winding of the bubble film.
