Description

Technical Field

[0001] This invention relates to the field of sponge pad production and processing technology, specifically to a continuous film-coating and winding device for sponge pad packaging. Background Technology

[0002] Sponge pads are soft, elastic, and absorbent materials, typically made of sponge or foam. They can be used for a variety of applications such as water absorption, cleaning, wiping, cushioning, and insulation. Sponge pads are widely used in home cleaning, car cleaning, beauty care, industrial cleaning, and healthcare. Different types of sponge pads have different characteristics and uses, such as fine-pore sponge pads, multi-functional sponge pads, and polishing sponge pads.

[0003] Currently, when producing and packaging sponge pads, it is necessary to coat the surface of the sponge pads with a film to prevent them from getting damp after packaging. Existing sponge pad packaging equipment is usually a winding packaging equipment, which directly holds the sponge pads in a restricting mechanism with two rollers, winds them up, and then pushes them out axially to achieve packaging. However, sponge pads are elastic, and during the direct winding process, the sponge pads are squeezed by their own winding and the restricting mechanism. The volume reduction after winding is limited, and they still occupy a large space, requiring larger packaging boxes for packaging.

[0004] To address this, we propose a continuous film-coating and winding device for foam pad packaging. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a continuous film-coating and winding device for sponge pad packaging, which solves the aforementioned technical problems.

A heat-sealing cutter is rotatably mounted inside the cutting frame.

[0012] Preferably, the dust removal assembly includes a dust removal frame, which is fixedly installed inside the feeding channel. Both sides of the dust removal frame are provided with feed ports, and two guide rollers are symmetrically arranged inside each of the two feed ports.

[0013] Preferably, movable frames are movably arranged at both the top and bottom of the dust removal frame, and one side of each movable frame is driven up and down by an electric slide table arranged on one side of the inner wall of the dust removal frame. A conveyor frame is rotatably arranged inside each of the two movable frames, and a cleaning brush is fixedly arranged on the surface of each of the two conveyor frames. The conveyor frames are driven to rotate by a drive wheel.

[0014] Preferably, each of the two movable frames is symmetrically provided with transmission rollers on one side, and a first pulley is fixedly provided at one end of each of the two transmission rollers. A double pulley is rotatably provided inside the movable frame, and the surface of the double pulley is connected to the surface of the first pulley by a belt drive. A second pulley is fixedly provided at one end of the drive wheel, and the surface of the second pulley is connected to the surface of the double pulley by a belt drive.

[0015] Preferably, dust suction ports are provided inside both of the movable frames and on both sides of the conveyor frame. A dust suction pump is fixedly installed on one side of the top of the laminating machine box, and the inlet of the dust suction pump is connected to the inside of the dust suction port through a dust suction pipe. A collection box is also fixedly installed on one side of the top of the laminating machine box, and the inside of the collection box is connected to the outlet of the dust suction pump through a conduit.

[0016] Preferably, the winding assembly includes a rotating frame, and rotating frames are rotatably arranged on the front and rear sides of the inner wall of the winding box. A second servo electric cylinder is fixedly arranged on the opposite side of the two rotating frames. A clamping frame is fixedly arranged on the drive end of the two second servo electric cylinders. A clamping plate is slidably arranged on the upper and lower sides of the inside of the clamping frame through an electric slider.

[0017] Preferably, a cutting rack is provided on one side inside the winding box, and a cutting tool is movably arranged on the side of the cutting rack near the rotating frame.

[0018] Preferably, a movable frame is slidably provided at the bottom of the winding box via an electric slide table, and a third servo electric cylinder is fixedly provided at the top of the movable frame. A guide frame is fixedly provided at the drive end of the third servo electric cylinder, and a limit clamp is slidably provided on one side of the guide frame via an electric slider.

[0019] Preferably, the top of the winding box is slidably equipped with a material transfer gripper via an electric slide table, and the material transfer gripper can rotate at multiple angles.

[0020] Preferably, the conveyor frame extends through the interior of the winding box.

[0021] Compared with existing technologies, it has the following advantages:

[0022] 1. In this invention, a feeding channel is set inside the laminating machine housing, and a dust removal component is set inside the feeding channel. The dust removal component is used to clean the dust on the surface of the sponge pad, ensuring the cleanliness of the sponge pad surface, improving the subsequent laminating effect of the sponge pad, and avoiding damage to the film layer on the surface of the sponge pad after laminating. Then, the upper and lower laminating components are used to continuously laminate the upper and lower surfaces of the sponge pad. During the laminating process, the sponge pad is squeezed by the laminating components, which reduces the volume of the laminating sponge pad, making it easier to roll the sponge pad in the subsequent winding process. This reduces the volume of the packaged sponge pad, making it easier to transport the sponge pad.

[0023] 2. In this invention, the first servo electric cylinder drives two laminating frames to approach the surface of the sponge pad until the pressure rollers on the two laminating frames flatten the sponge pad. At this time, the film material on the upper and lower laminating frames covers the upper and lower surfaces of the sponge pad respectively. The cutting frame controls the micro electric cylinder to heat-seal and cut the film material on both sides of the sponge pad, thereby realizing the overall laminating process of the sponge pad. As the sponge pad is conveyed from the left side to the right side of the laminating frame, the film material is fed out by the film feeding frame and the waste film material is collected by the film collecting frame, so that the film material is continuously laminating the upper and lower surfaces of the sponge pad, thereby improving the laminating efficiency of the sponge pad.

[0024] 3. In this invention, a winding box is installed inside the laminating machine housing, and a winding assembly is installed inside the winding box. After the laminating assembly completes the lamination process on the upper and lower surfaces of the sponge pad inside the laminating machine housing, the sponge pad is fed into the winding box. The winding assembly then winds the laminated sponge pad, achieving automatic winding of the sponge pad and facilitating its packaging. The rotating frame in the winding assembly winds the sponge pad. After reaching the desired winding length, a cutting frame on one side, in conjunction with a cutting blade, cuts one side of the sponge pad. At this point, the limiting clamps inside the guide frame clamp one side of the sponge pad. By releasing the two clamping plates from limiting the two sides of the sponge pad, and with the help of the transfer grippers, the wound sponge pad is sent into the packaging box to complete the packaging. Then, the guide frame sends one side of the sponge pad between the two rotating frames, and the clamping plates inside the two clamping frames clamp the two sides of the sponge pad to continue the winding process. This achieves continuous film coating, winding and packaging of the sponge pad. The whole process is automated and requires no manual operation, which significantly improves the packaging efficiency of the sponge pad. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] Please see Figures 1 to 8 As shown, a continuous film-coating and winding device for foam pad packaging includes:

[0037] The laminating machine housing 1 has a feed inlet 2 on its left side and a conveyor frame 3 running through the middle of its interior. The sponge pads are fed into the laminating machine housing 1 through the feed inlet 2 and the packaging boxes of the sponge pads are sent into the laminating machine housing 1 through the conveyor frame 3. After the laminating and winding process of the sponge pads is completed inside the laminating machine housing 1, the sponge pads are sent into the packaging boxes for automatic packaging. The continuous laminating and winding process of the sponge pads inside the laminating machine housing 1 significantly improves the production and processing efficiency of the sponge pads.

[0038] The dust removal component is provided on the left side of the inside of the laminating machine box 1. The dust removal component is installed inside the dust removal component. After the sponge pad is sent into the inside of the laminating machine box 1 through the feed port 2, the dust removal component is used to clean the dust on the surface of the sponge pad to ensure the cleanliness of the sponge pad surface, improve the subsequent laminating effect of the sponge pad, and avoid damage to the film layer on the surface of the sponge pad after laminating.

[0039] The laminating assembly has a fixed frame 5 inside the laminating machine housing 1, and laminating assemblies are movably installed inside the fixed frame 5 and above the laminating machine housing 1. The upper and lower laminating assemblies are used to continuously laminate the upper and lower surfaces of the sponge pad. When laminating the surface of the sponge pad, the laminating assemblies squeeze the sponge pad to reduce its volume after lamination, which facilitates the subsequent winding of the sponge pad and reduces its volume after winding. This reduces the volume of the packaging box for the sponge pad and makes it easier to transport the sponge pad.

[0040] The winding assembly is located at the bottom of the laminating machine housing 1, and the winding assembly is installed inside the winding housing 6. The conveyor frame 3 passes through the inside of the winding housing 6. After the laminating assembly completes the laminating process on the upper and lower surfaces of the sponge pad inside the laminating machine housing 1, the sponge pad is sent into the inside of the winding housing 6. The winding assembly then winds the laminating sponge pad to achieve automatic winding of the sponge pad, which facilitates the packaging of the sponge pad.

[0041] Furthermore, the above structure has the following advantages compared with the prior art:

[0042] In this invention, a dust removal component is used inside the laminating machine housing 1 to clean the dust on the surface of the sponge pad, ensuring the cleanliness of the sponge pad surface and improving the subsequent laminating effect. This prevents damage to the film layer on the surface of the sponge pad after laminating. Then, two laminating components are used to continuously laminate the upper and lower surfaces of the sponge pad. During the laminating process, the sponge pad is squeezed by the laminating components, reducing the volume of the laminated sponge pad. This facilitates the subsequent winding process of the sponge pad, reducing the volume of the packaged sponge pad and making it easier to transport.

[0043] Furthermore, the dust removal assembly includes a dust removal frame 7, which is fixedly installed inside the feeding channel 4. Both sides of the dust removal frame 7 are provided with material passages. Two guide rollers 8 are symmetrically arranged inside each of the two material passages. Movable frames 9 are movably installed at the top and bottom inside the dust removal frame 7. One side of the two movable frames 9 is driven up and down by an electric slide table set on one side of the inner wall of the dust removal frame 7. A conveyor frame 10 is rotatably installed inside each of the two movable frames 9. Cleaning brushes 11 are fixedly installed on the surface of each of the two conveyor frames 10. The conveyor frame 10 is driven to rotate inside by a drive wheel.

[0044] Two movable frames 9 are symmetrically arranged with transmission rollers 12 on opposite sides, and one end of each transmission roller 12 is fixedly provided with a first pulley 13. A double pulley 14 is rotatably arranged inside the movable frame 9, and the surface of the double pulley 14 is connected to the surface of the first pulley 13 by belt drive. One end of the drive wheel is fixedly provided with a second pulley 15, and the surface of the second pulley 15 is connected to the surface of the double pulley 14 by belt drive.

[0045] Furthermore, dust suction ports 16 are provided inside the two movable frames 9 and on both sides of the conveyor frame 10. A dust suction pump 17 is fixedly installed on one side of the top of the laminating machine box 1, and the inlet of the dust suction pump 17 is connected to the inside of the dust suction port 16 through a dust suction pipe. A collection box 18 is also fixedly installed on one side of the top of the laminating machine box 1, and the inside of the collection box 18 is connected to the outlet of the dust suction pump 17 through a conduit.

[0046] It should be noted that when cleaning the surface of the sponge pad, the sponge pad is passed through the interior of the cleaning frame 7, and then the two movable frames 9 are controlled to approach the upper and lower surfaces of the sponge pad respectively until the transmission rollers 12 on the two movable frames 9 contact the surface of the sponge pad. When the sponge pad is being transported, the sponge pad drives the four transmission rollers 12 to rotate inside the two movable frames 9 respectively. Through the cooperation and connection between the transmission rollers 12, the first pulley 13, the double pulleys 14 and the second pulley 15 and the drive wheel, the drive wheel rotates synchronously with the transmission rollers 12. The drive wheel drives the conveyor frame 10 to rotate, thereby cleaning the dust and impurities on the surface of the sponge pad through the cleaning brushes 11 set on the surface of the conveyor frame 10. Then, the cleaned dust and impurities are pumped into the collection box 18 through the dust suction ports 16 on both sides of the interior of the movable frame 9 by the dust suction pump 17 for storage, so as to avoid the dust and impurities contaminating the interior of the cleaning frame 7 and affecting the subsequent coating treatment of the sponge pad surface.

[0047] Example 2:

[0048] This embodiment specifically discloses the structural composition of the coating assembly, which includes a coating frame 19. The top of the fixed frame 5 and the upper part of the interior of the coating machine housing 1 are both movably equipped with coating frames 19, and several pressure rollers 20 are rotatably arranged on opposite sides of the two coating frames 19. The top of the coating machine housing 1 and the bottom of the fixed frame 5 are both fixedly equipped with first servo cylinders 21, and the drive ends of the upper and lower sets of first servo cylinders 21 are respectively fixedly connected to one side of the upper and lower coating frames 19. The two sides inside the coating frame 19 are respectively rotatably equipped with a film feeding frame 22 and a film receiving frame 23. The interior of the coating frame 19 is fixedly equipped with a micro electric cylinder 24, and the drive end of the micro electric cylinder 24 is fixedly equipped with a cutting frame 25. The interior of the cutting frame 25 is rotatably equipped with a heat sealing cutter 26.

[0049] It should be noted that during the lamination process of the sponge pad, the sponge pad is passed between two lamination frames 19. The upper and lower first servo electric cylinders 21 drive the two lamination frames 19 to approach the surface of the sponge pad until the pressure rollers 20 on the two lamination frames 19 flatten the sponge pad. At this time, the film material on the upper and lower lamination frames 19 covers the upper and lower surfaces of the sponge pad respectively. The cutting frame 25 controls the micro electric cylinder 24 to heat-seal and cut the film material on both sides of the sponge pad, thereby realizing the overall lamination process of the sponge pad. As the sponge pad is conveyed from the left side to the right side of the lamination frame 19, the film material is fed out by the film feeding frame 22 and the film waste is collected by the film receiving frame 23, so that the film material is continuously laminationd on the upper and lower surfaces of the sponge pad, thereby improving the lamination process efficiency of the sponge pad.

[0050] Example 3:

[0051] This embodiment mainly discloses the specific structural description of the winding assembly. The winding assembly includes a rotating frame 27. The rotating frame 27 is rotatably arranged on the front and rear sides of the inner wall of the winding box 6. A second servo electric cylinder 28 is fixedly arranged on the opposite side of the two rotating frames 27. A clamping frame 29 is fixedly arranged on the drive end of the two second servo electric cylinders 28. A clamping plate 30 is slidably arranged on the upper and lower sides of the inside of the clamping frame 29 through an electric slider. A cutting frame is arranged on one side of the inside of the winding box 6. A cutting tool is movably arranged on the side of the cutting frame close to the rotating frame 27.

[0052] Inside the winding box 6, a movable frame 31 is slidably mounted on the bottom via an electric slide table, and a third servo electric cylinder 32 is fixedly mounted on the top of the movable frame 31. A guide frame 33 is fixedly mounted on the drive end of the third servo electric cylinder 32, and a limit clamp is slidably mounted on one side of the guide frame 33 via an electric slider.

[0053] The top of the winding box 6 is equipped with a material transfer gripper 34 via an electric slide table, and the material transfer gripper 34 can rotate at multiple angles.

[0054] It should be noted that during the winding process of the laminated sponge pad, the laminated sponge pad is fed into the winding box 6. One side of the sponge pad is guided between two rotating frames 27 by the guide frame 33. The second servo cylinder 28 on one side of the rotating frame 27 drives the two clamping frames 29 to move closer together until the interior of the two clamping frames 29 is located on both sides of the sponge pad. The clamping plates 30 inside the two clamping frames 29 clamp the two sides of the sponge pad. Then, the two rotating frames 27 are rotated to wind the sponge pad. After the desired winding length is reached, a cutting frame on one side is used to cut the sponge pad. The cutting tool cuts off one side of the sponge pad. At this time, the limiting clamping block inside the guide frame 33 limits and clamps one side of the sponge pad. By releasing the limiting of the two clamping plates 30 on both sides of the sponge pad, the transfer gripper 34 sends the wound sponge pad into the packaging box to complete the packaging. Then, the guide frame 33 sends one side of the sponge pad between the two rotating frames 27. The clamping plates 30 inside the two clamping frames 29 clamp both sides of the sponge pad and continue to perform the winding process of the sponge pad. This realizes the continuous film coating, winding and packaging process of the sponge pad. The whole process is automated and no manual operation is required, which significantly improves the packaging efficiency of the sponge pad.

[0055] Example 4:

[0056] This embodiment mainly discloses a working method of a continuous film-coating and winding device for sponge pad packaging, which specifically includes the following steps:

[0057] Step 1: Feed a sponge pad into the interior of the laminating machine housing 1 through the feed port 2. Pass the sponge pad through the interior of the dust removal frame 7. Then, control the two movable frames 9 to approach the upper and lower surfaces of the sponge pad respectively until the transmission rollers 12 on the two movable frames 9 contact the surface of the sponge pad. When the sponge pad is being conveyed, the sponge pad drives the four transmission rollers 12 to rotate inside the two movable frames 9 respectively. Through the cooperation and connection between the transmission rollers 12, the first pulley 13, the double pulley 14 and the second pulley 15 and the drive wheel, the drive wheel rotates synchronously with the transmission rollers 12. The drive wheel drives the conveyor frame 10 to rotate, thereby cleaning the dust and impurities on the surface of the sponge pad through the cleaning brush 11 set on the surface of the conveyor frame 10. Then, the cleaned dust and impurities are pumped into the collection box 18 for storage through the dust suction ports 16 on both sides of the interior of the movable frame 9 by the dust suction pump 17.

[0058] Step 2: Pass the sponge pad through the two laminating frames 19. Use the drive end of the first servo electric cylinder 21 above and below to control the two laminating frames 19 to move closer to the surface of the sponge pad until the pressure rollers 20 on the two laminating frames 19 flatten the sponge pad. At this time, the film material on the upper and lower laminating frames 19 covers the upper and lower surfaces of the sponge pad respectively. Use the drive end of the micro electric cylinder 24 to control the cutting frame 25 to heat seal and cut the film material on both sides of the sponge pad, so as to realize the overall laminating process of the sponge pad. As the sponge pad is conveyed from the left side to the right side of the laminating frame 19, the film material is fed by the film feeding frame 22 and the film waste is collected by the film collecting frame 23, so that the film material is continuously laminating the upper and lower surfaces of the sponge pad.

[0059] Step 3: When winding the coated sponge pad, the coated sponge pad is fed into the winding box 6. One side of the sponge pad is fed between two rotating frames 27 by the guide frame 33. The second servo cylinder 28 on one side of the rotating frame 27 drives the two clamping frames 29 to move closer together until the interior of the two clamping frames 29 is located on both sides of the sponge pad. The clamping plates 30 inside the two clamping frames 29 clamp the two sides of the sponge pad. Then, the two rotating frames 27 are controlled to rotate, and the sponge pad is wound using the rotating frames 27 until the desired winding length is reached. Then, the cutting rack on one side, together with the cutting blade, cuts one side of the sponge pad. At this time, the limiting clamping block inside the guide rack 33 limits and clamps one side of the sponge pad. By releasing the limiting of the two clamping plates 30 on both sides of the sponge pad, the transfer claw 34 sends the wound sponge pad into the packaging box to complete the packaging. Then, the guide rack 33 sends one side of the sponge pad between the two rotating racks 27. The clamping plates 30 inside the two clamping racks 29 clamp both sides of the sponge pad and continue to perform the winding process of the sponge pad, realizing the continuous film coating, winding and packaging process of the sponge pad.
