Description

Technical Field

[0001] This utility model relates to the field of bottled water processing technology, and more specifically, it relates to a bottled water film cutting device. Background Technology

[0002] In the existing bottled water production and packaging process, in order to achieve brand logo display, scratch protection and improved transportation stability, most bottled water bottles are wrapped with a layer of plastic packaging film on the side wall. This side wall packaging film needs to be precisely attached to the bottle body after filling. Currently, the cutting of the sidewall packaging film of bottled water is still mainly done manually in the industry. Operators need to hold the cutting tool and cut around the bottle. This is not only labor-intensive and inefficient, but also makes it difficult to ensure the straightness and consistency of the cutting trajectory. Because the sidewall of bottled water has an arc-shaped curved surface structure, the cutting tool is very prone to slippage during manual cutting, resulting in uneven cutting edges. This not only affects the appearance quality of the product, but may also scratch the bottle material due to improper force, causing damage to the sealing performance of the bottled water. Meanwhile, in large-scale production, the cutting force and speed of different operators vary, making it difficult to achieve standardized cutting results. This increases the workload of subsequent quality inspection. In addition, manual operation with handheld blades for extended periods poses a high safety risk. Accidental contact between the blade and the operator or spillage of bottled water are common occurrences, threatening production safety and potentially causing unnecessary material loss.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A barrel-type water-cutting film device includes a base plate, a rotating rod disposed at the center of the side wall of the base plate, a placement tray disposed on the rotating rod, a first motor disposed on the bottom wall of the base plate, the lower end of the rotating rod penetrating the base plate and connected to the output end of the first motor, a support rod disposed at the rear end of the side wall of the base plate, a support plate disposed at the upper end of the support rod, a cylinder disposed at the front end of the support plate, a fixing block disposed at the lower end of the cylinder, a positioning plate rotatably connected to the fixing block at the lower end of the fixing block, a limit component disposed at the connection between the base plate and the placement tray, an auxiliary plate disposed on one side of the base plate, a winding mechanism disposed at one end of the auxiliary plate, and a cutting component disposed on one side of the base plate.

[0005] The present invention is further configured such that the limiting component includes a positioning ring and a slider. The positioning ring is located on the side wall of the base plate, and the slider is symmetrically arranged at the lower end of the placement plate. The lower end of the slider is provided with a groove, which is adapted to and slidably connected to the positioning ring, providing stable guidance for the rotation of the placement plate and preventing the placement plate from shifting or shaking during rotation.

[0006] The present invention is further configured such that the winding mechanism includes a winding rod, a second motor and a limiting block, the winding rod is located at the upper end of the auxiliary plate, the second motor is located at the lower end of the auxiliary plate, the winding rod passes through the auxiliary plate and is connected to the output end of the second motor, and the limiting block is located at the upper end of the winding rod and is detachably connected to it, thereby realizing automatic winding of the film.

[0007] The present invention is further configured such that the cutting assembly includes a fixed box, a lifting rod, a lifting block, an electric push rod, and a cutting blade. The fixed box is located on one side of the base plate, the lifting rod passes through the fixed box, the lifting block is on the lifting rod and threadedly connected to it, a third motor is provided at the upper end of the fixed box, the upper end of the lifting rod is connected to the output end of the third motor, the lifting block is fitted against and slidably connected to the inner wall of the fixed box, the rear end of the electric push rod passes through the fixed box and is connected to the lifting block, the cutting blade is located at the front end of the electric push rod, and a disassembly assembly is provided at the connection between the cutting blade and the electric push rod, thereby achieving precise cutting of the film on the side wall of bottled water, replacing manual cutting and improving efficiency.

[0008] The present invention is further configured such that the disassembly assembly includes a disassembly box, a disassembly block, and screws. The disassembly box is located at the front end of the electric push rod, and the disassembly block is located at the rear side of the cutting blade. The disassembly block passes through the disassembly box and is slidably connected to it.

[0011] (III) Beneficial Effects Compared with the prior art, the present invention provides a barrel-type water-cutting film device, which has the following beneficial effects: 1. The precise matching and sliding of the positioning ring and the slider groove provides a stable circumferential motion trajectory for the placement tray, avoiding cutting deviations caused by tray offset or shaking during the cutting process of bottled water. This ensures that the cutting position always accurately corresponds to the pre-set cutting line of the film, fundamentally solving the problem of inconsistent cutting quality caused by bottle instability during manual operation. At the same time, the first motor drives the rotating rod to rotate the placement tray at a uniform speed, which, together with the downward pressure and fixation of the positioning plate, further ensures the fixed position of the bottled water during the cutting process, laying a solid foundation for subsequent precise cutting.

[0012] 2. In the cutting assembly, the third motor drives the lifting block to flexibly adjust the height via the lifting rod, which can easily adapt to the side wall height of different sizes of bottled water and meet diverse cutting needs. The electric push rod pushes the cutting blade to precisely approach the bottle wall, realizing continuous cutting of the side wall film. This replaces the traditional manual hand-held cutting method, which not only greatly improves cutting efficiency, but also ensures the consistency and flatness of the cutting trajectory through the stable operation of the mechanical structure, effectively avoiding problems such as rough edges and uneven depths that are prone to occur during manual cutting.

[0013] 3. The winding mechanism is driven by a second motor to rotate the winding rod, which can automatically wind up the film produced by cutting in real time, reducing the tedious steps of manual feeding and reducing the labor intensity of operators. Attached Figure Description

[0019] Please see Figure 1-5 A barrel-type water-cutting film device includes a base plate 1, a rotating rod 2 disposed at the center of the upper side wall of the base plate 1, a placement tray 3 disposed on the rotating rod 2, a first motor 4 disposed on the bottom wall of the base plate 1, the lower end of the rotating rod 2 passing through the base plate 1 and connected to the output end of the first motor 4, a support rod 5 disposed at the rear end of the upper side wall of the base plate 1, a support plate 6 disposed at the upper end of the support rod 5, a cylinder 7 disposed at the front end of the support plate 6, a fixing block 8 disposed at the lower end of the cylinder 7, a positioning plate 9 rotatably connected to the fixing block 8, a limit component disposed at the connection between the base plate 1 and the placement tray 3, an auxiliary plate 10 disposed on one side of the base plate 1, a winding mechanism disposed at one end of the auxiliary plate 10, and a cutting component disposed on one side of the base plate 1.

[0020] The limiting component includes a positioning ring 11 and a slider 12. The positioning ring 11 is on the upper side wall of the base plate 1, and the slider 12 is symmetrically arranged at the lower end of the placement plate 3. The lower end of the slider 12 is provided with a groove, which is adapted to and slidably connected to the positioning ring 11.

[0021] The winding mechanism includes a winding rod 13, a second motor 14, and a limiting block 15. The winding rod 13 is located at the upper end of the auxiliary plate 10, and the second motor 14 is located at the lower end of the auxiliary plate 10. The winding rod 13 passes through the auxiliary plate 10 and is connected to the output end of the second motor 14. The limiting block 15 is located at the upper end of the winding rod 13 and is detachably connected to it.

[0022] In this embodiment, preliminary preparations are first performed. The operator installs the rolled packaging film onto the winding rod 13 of the winding mechanism and fixes the film roll with a detachable limiting block 15 to prevent the film roll from shifting or falling off during subsequent rotation. Then, the bottled water to be coated is placed stably on the placement tray 3, ensuring that the center of the bottle is roughly aligned with the center of the placement tray 3, laying the foundation for the accuracy of subsequent coating and cutting. After the preparations are completed, the cylinder 7 at the front end of the support plate 6 is activated. The piston rod of the cylinder 7 extends downward, driving the fixing block 8 and the positioning plate 9 at the lower end to move down synchronously. The positioning plate 9 contacts the top of the bottled water for fixation, ensuring a tight fit with the top surface of the bottle, achieving stable clamping of the top of the bottled water, and preventing the bottled water from shifting during subsequent rotation. If shaking or displacement occurs, the operator pulls out one end of the packaging film on the winding rod 13 and manually attaches the starting end of the film to the preset position on the side wall of the bottled water to complete the positioning before film application. Then, the first motor 4 and the second motor 14 are started. The first motor 4 drives the rotating rod 2 to rotate the placement tray 3 and the bottled water at a uniform speed, while the second motor 14 drives the winding rod 13 to rotate synchronously to release the packaging film. During the rotation of the bottled water, the packaging film is continuously pulled out and tightly attached to the side wall of the bottle, realizing automated film application. The slider 12 in the limiting component rotates synchronously with the placement tray 3. The matching sliding of its groove and the positioning ring 11 provides a stable guide for the placement tray 3, ensuring the consistency of the bottled water's rotation trajectory and ensuring that the film surface is flat and wrinkle-free during the film application process.

[0023] More specifically, after the film application is completed, the first motor 4 and the second motor 14 are turned off, the bottled water stops rotating, and the winding rod 13 also stops releasing the film. At this time, the cutting assembly is started, and the third motor 21 drives the lifting rod 17 to rotate. Through the threaded transmission, the lifting block 18 moves up and down along the inner wall of the fixed box 16, adjusting the cutting blade 20 to the height corresponding to the film application position on the side wall of the bottled water. Then, the electric push rod 19 extends forward, pushing the cutting blade 20 close to the side wall of the bottle. After the cutting blade 20 contacts the film, the third motor 21 is started again to cut, accurately cutting off the excess film. After the cutting is completed, the electric push rod 19 drives the cutting blade 20 to reset, and the cylinder 7 drives the positioning plate 9 to move up to release the bottled water. The operator can then remove the bottled water that has been filmed and cut, and the entire workflow is completed.

[0024] Please see Figures 1-5As one embodiment of the cutting assembly: the cutting assembly includes a fixed box 16, a lifting rod 17, a lifting block 18, an electric push rod 19, and a cutting blade 20. The fixed box 16 is located on one side of the base plate 1. The lifting rod 17 passes through the fixed box 16. The lifting block 18 is on the lifting rod 17 and threadedly connected to it. A third motor 21 is provided at the upper end of the fixed box 16. The upper end of the lifting rod 17 is connected to the output end of the third motor 21. The lifting block 18 is fitted against and slidably connected to the inner wall of the fixed box 16. The rear end of the electric push rod 19 passes through the fixed box 16 and is connected to the lifting block 18. The cutting blade 20 is located at the front end of the electric push rod 19. A disassembly assembly is provided at the connection between the cutting blade 20 and the electric push rod 19.

[0025] Specifically, the cutting assembly is activated, and the third motor 21 drives the lifting rod 17 to rotate. Through threaded transmission, the lifting block 18 moves up and down along the inner wall of the fixed box 16, adjusting the cutting blade 20 to the starting cutting height for the film on the side wall of the bottled water. Then, the electric push rod 19 extends forward, pushing the cutting blade 20 close to and in contact with the film on the side wall of the bottle, so that the cutting blade 20 is precisely against the preset cutting position. After that, the third motor 21 is activated again, driving the lifting rod 17 to rotate, which in turn drives the lifting block 18, the electric push rod 19, and the cutting blade 20 to move smoothly down along the inner wall of the fixed box 16. During the downward movement, the cutting blade 20 makes a straight cut in the vertical direction of the film on the side wall of the bottled water, cutting the film according to the preset trajectory.

[0026] Please see Figures 1-5 As one embodiment of the disassembly assembly: the disassembly assembly includes a disassembly box 22, a disassembly block 23 and a screw 24. The disassembly box 22 is at the front end of the electric push rod 19, the disassembly block 23 is at the rear side of the cutting blade 20, the disassembly block 23 passes through the disassembly box 22 and is slidably connected to it, and the screw 24 fixes the disassembly box 22 and the disassembly block 23.

[0027] Specifically, loosen the screws 24 that secure the disassembly box 22 and the disassembly block 23, slide the disassembly block 23 on the rear side of the cutter 20 out of the disassembly box 22, replace the new cutter 20, and then re-secure the disassembly block 23 through the disassembly box 22 with the screws 24 to ensure that the cutter 20 is securely installed.

[0028] Please see Figures 1-5 As one embodiment of the movable wheel 25: movable wheels 25 are provided at the four corners of the bottom wall of the base plate 1, and brake components adapted to them are provided on the movable wheels 25.

[0029] Specifically, the operator pushes the device according to production needs, and uses the four corners of the bottom wall of the base plate 1 to move the device flexibly to the appropriate working position. After reaching the designated position, the operator operates the brake assembly on the moving wheel 25 to fix the device firmly.

[0030] Please see Figures 1-5 As one implementation of the wear-resistant layer: the inner wall of the groove at the lower end of the slider 12 is provided with a wear-resistant layer, which is made of polytetrafluoroethylene.

[0031] Specifically, the wear-resistant polytetrafluoroethylene layer on the inner wall of the groove effectively reduces frictional loss between the slider 12 and the positioning ring 11, ensuring the smoothness and stability of the sliding process.

[0032] In summary, when using the overall equipment: First, the operator needs to install the film roll to be used onto the winding rod 13 of the winding mechanism and fix the film roll with the limiting block 15 to ensure that the film roll will not shift or fall off during subsequent rotation. Next, place the bottled water that needs to be coated on the placement tray 3. When placing it, ensure that the center of the bottle is roughly aligned with the center of the placement tray 3 so that the subsequent coating process can proceed smoothly.

[0033] Activate the cylinder 7 at the front end of the support plate 6. The cylinder 7 will push the lower fixing block 8 to move downward. The fixing block 8 will drive the positioning plate 9, which is rotatably connected to it, to move downward in sync until the positioning plate 9 contacts the top of the bottled water and forms a stable clamp. At this time, the positioning plate 9 can fix the top of the bottle and prevent the bottle from shaking or shifting during the subsequent film placement, film application and cutting process, thus ensuring the stability of the overall operation.

[0034] After securing the container, the operator manually pulls out one end of the membrane roll and flattens it against the side wall of the bottled water, ensuring the starting end of the membrane is in close contact with the container wall. Then, simultaneously, the first motor 4 on the bottom wall of the base plate 1 and the second motor 14 at the lower end of the auxiliary plate 10 are started. After the first motor 4 starts, its output end drives the rotating rod 2 to rotate, which in turn drives the placement tray 3 and the bottled water placed on it to rotate together. After the second motor 14 starts, its output end drives the winding rod 13 to rotate, and the winding rod 13 gradually releases the membrane roll as the bottled water... As the container rotates, the released film will evenly wrap around and adhere to the side wall of the container, achieving an automatic film release and application process. During this process, the slider 12 at the lower end of the placement tray 3 will slide along the positioning ring 11 on the base plate 1. The positioning ring 11 is adapted to the groove at the lower end of the slider 12, which not only provides guidance for the rotation of the placement tray 3, but also effectively limits the movement range of the placement tray 3, further ensuring the stability of the bottled water rotation. At the same time, the polytetrafluoroethylene wear-resistant layer on the inner wall of the groove at the lower end of the slider 12 can reduce the friction between the slider 12 and the positioning ring 11, extending the service life of the components.

[0035] Once the film is fully adhered to the side wall of the container, completing the film application process, turn off the first motor 4 and the second motor 14 to stop the film placement and container rotation. Next, start the cutting assembly for the cutting operation. First, start the third motor 21 at the top of the fixing box 16 according to the required cutting position. The output of the third motor 21 will drive the lifting rod 17 to rotate. Since the lifting block 18 is threadedly connected to the lifting rod 17 and slides against the inner wall of the fixing box 16, the rotation of the lifting rod 17 will be converted into the up and down movement of the lifting block 18, thereby driving the electric push rod 19 and the cutting blade 20 to move up and down together. Adjust the cutting blade 20 to the appropriate cutting height. After adjusting the height of the cutting blade 20, start the electric push rod 19. The electric push rod 19 will push the cutting blade 20 at the front end forward, so that the cutting blade 20 contacts the film on the container wall. At the same time, the up and down position of the cutting blade 20 can be adjusted by the third motor 21 to achieve cutting the film in the up and down direction.

[0036] If a ring cut is required, the cutting blade 20 with a different orientation can be replaced, aligning the blade tip with the membrane. The first motor 4 is then restarted to rotate the water tank again. Simultaneously, the electric push rod 19 is activated to bring the cutting blade 20 into contact with the membrane. As the tank rotates, the cutting blade 20 will cut along the ring direction of the membrane, completing the ring cut operation. The cutting blade 20 and the electric push rod 19 are connected by a disassembly assembly. When the cutting blade 20 is worn or needs to be replaced with a different type of cutting blade 20, the screw 24 can be unscrewed, the disassembly block 23 can be removed from the disassembly box 22, a new cutting blade 20 can be replaced, and then it can be re-fixed. The operation is convenient and quick.

[0037] In addition, the casters 25 at the four corners of the bottom wall of the base plate 1 make it easy for operators to move the entire device as needed. When the device is moved to a suitable position, it can be fixed by the brake assembly on the casters 25 to prevent the device from moving during operation.

[0038] In all the solutions mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.

The scope of this utility model is defined by the appended claims and their equivalents. In all the solutions mentioned above, the operation of electrical components is controlled by a controller.
