Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a non-woven fabric wrapping machine. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, is composed of oriented or randomly arranged fibers. It is called cloth because it has the appearance and some properties of cloth. Non-woven fabric has the characteristics of being moisture-proof, breathable, flexible, lightweight, non-flammable, easily degradable, non-toxic and non-irritating, rich in color, inexpensive, and recyclable. In the non-woven fabric industry, it is necessary to roll it up and package it for convenient subsequent transportation and sales.

[0003] Most existing stretch wrapping machines use a single-specification slot or simple binding method, which is difficult to adapt to non-woven fabric rolls of different widths and diameters. Changing product specifications requires a lot of time for adjustment. At the same time, the non-woven fabric roll is rotated by a turntable, which can then wrap the stretch film. An existing patent (publication number: CN220925946U) discloses a wrapping machine for spunlace nonwoven fabric. By opening the snap-fit ​​cover, one side of the spunlace nonwoven fabric is placed between the first groove and the snap-fit ​​cover. Then, using a fixing buckle, the hook of the fixing buckle is hooked onto the buckle ring. Pulling down the buckle wrench fixes the snap-fit ​​cover, thus fixing the spunlace nonwoven fabric on the packaging drum and preventing it from slipping off the packaging drum, ensuring the smoothness of the wrapping film.

[0004] To address the aforementioned issues, existing patents offer solutions, but they are not convenient for restricting the stretch film. During the nonwoven fabric packaging process, the stretch film relies on the rotation of the nonwoven fabric roll for passive traction and winding. Due to the lack of restricting components, when the nonwoven fabric roll rotates too fast, the stretch film is prone to shifting during movement, resulting in uneven winding. This not only wastes a large amount of stretch film but also requires rework, wasting a lot of time, affecting the packaging effect and efficiency of the nonwoven fabric, and reducing the practicality of the device.

[0005] Therefore, a nonwoven fabric wrapping machine is proposed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: A nonwoven fabric wrapping machine includes a base 1, a limiting component 2 is fixedly connected to the top of the base 1, and a winding component 3 is fixedly connected to the right side of the top of the base 1. The winding component 3 includes an L-shaped plate 301, a movable plate 302 is movably connected to the top inside the L-shaped plate 301, and hydraulic cylinders 303 are fixedly connected to both sides of the bottom of the movable plate 302. The limiting component 2 includes a fixed frame 201. The top of the front and rear sides of the inner wall of the fixed frame 201 are provided with a sliding groove 202. The inside of the sliding groove 202 is fixedly connected to a positioning rod 203. The surfaces of the two positioning rods 203 are slidably connected to sliders 204. The opposite sides of the two sliders 204 are rotatably connected to a pressing roller 205. The top of the two sliders 204 is fixedly connected to a spring 206. The spring 206 is sleeved on the surface of the positioning rod 203. The bottom of the inside of the fixed frame 201 is rotatably connected to a support roller 207. The support roller 207 is located at the bottom of the pressing roller 205.

[0020] In this embodiment: by rotating the bolt 308, the locking of the movable ring 306 is released, allowing it to move smoothly under the constraint of the connecting rod 304. This allows for flexible adjustment of the spacing between the clamping plates 307 according to actual conditions, achieving the fixing of non-woven fabric rolls of specific specifications. In conjunction with the rotating motor 305, the connecting rod 304 can be rotated to complete the winding of the non-woven fabric roll and the wrapping of the stretch film. Simultaneously, under the action of the hydraulic cylinder 303, the movable plate 302 and the connecting rod 304 can be vertically raised and lowered, ensuring they are always in the appropriate position, improving the ease of use of the winding assembly 3. Then, the pressing roller 205 is moved, causing the slider 204 to move approximately within the positioning rod 203. The smooth movement of the spring 206 under the tension can restrict the movement of the pressing roller 205, thus releasing the restrictive effect of the limiting component 2 and allowing the stretch film to pass through smoothly. After the stretch film is in place, the elasticity of the spring 206 drives the slider 204 to reset with the pressing roller 205, causing the stretch film to contact the support roller 207. The two work together to form a dynamic restriction, ensuring the smooth and stable movement of the stretch film and avoiding uneven wrapping. In conjunction with the electric trolley 10, the cutting blade 11 can be moved to achieve fast and accurate film cutting, avoiding problems such as rough edges and tears, providing reliable protection for continuous packaging, and improving the ease of use of the limiting component 2.

[0021] Specifically, such as Figure 5 As shown, a connecting rod 304 is rotatably connected to the top of the front side of the movable plate 302, and a rotating motor 305 is fixedly connected to the rear side of the connecting rod 304. Moving rings 306 are slidably connected to both the front and rear sides of the surface of the connecting rod 304, and clamping plates 307 are fixedly connected to the opposite sides of the two moving rings 306. Bolts 308 are threadedly connected to the top of the moving rings 306, and the bottom of the bolts 308 extends into the interior of the connecting rod 304.

[0022] Specifically, such as Figure 5 As shown, a connecting groove 4 is provided at the bottom of the inner wall of the L-shaped plate 301. Support rollers 5 are rotatably connected to both sides inside the connecting groove 4, and the connecting rod 304 is located at the top of the two support rollers 5.

[0023] Specifically, such as Figure 5 As shown, the top of the connecting rod 304 has several threaded holes 6 for use with bolts 308, and the surface of the bolt 308 is in contact with the inner wall of the threaded hole 6.

[0024] In this embodiment: the bolt 308 is used in conjunction with the threaded hole 6, so that the bolt 308 passes through the movable ring 306 and extends into the threaded hole 6 to form a mechanical lock. The spacing between the clamping plates 307 can be adjusted according to the actual situation to fix the non-woven fabric roll of a specific specification. At the same time, under the action of the support roller 5, the non-woven fabric roll comes into contact with the support roller 5 to form a low-friction rolling support, ensuring the smooth rotation of the non-woven fabric roll and improving the ease of use of the winding assembly 3.

[0025] Specifically, such as Figure 4 As shown, both sliders 204 have movable holes 7 inside for use with positioning rods 203, and the surface of positioning rods 203 is in contact with the inner wall of movable holes 7.

[0026] Specifically, such as Figure 4 As shown, a connecting frame 8 is fixedly connected to the right side of the fixed frame 201, and a guide block 9 is fixedly connected to the top and bottom of the inner wall of the connecting frame 8. An electric trolley 10 is movably connected to the surface of the two guide blocks 9, and a cutting blade 11 is fixedly connected between the two electric trolleys 10.

[0027] In this embodiment: the positioning rod 203 and the moving hole 7 work together to allow the slider 204 to move smoothly under the constraint of the positioning rod 203 and compress the spring 206, thus achieving the limiting effect of the limiting component 2 and allowing the stretch film to pass through smoothly. After the stretch film is in place, the spring 206 acts elastically to drive the slider 204 and the pressing roller 205 to reset, forming a dynamic constraint with the support roller 207. This ensures the smooth and stable movement of the stretch film and improves the ease of use of the limiting component 2. Then, under the action of the electric trolley 10, the cutting blade 11 can be driven to move smoothly under the constraint of the guide block 9. The cutting blade 11 moves synchronously to complete the precise film cutting, avoiding problems such as rough edges and tears, providing a reliable guarantee for continuous packaging, and improving the packaging efficiency and quality of nonwoven fabric.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3As shown, an L-shaped bracket 12 is fixedly connected to the left side of the top of the base 1, and a threaded rod 13 is rotatably connected inside the L-shaped bracket 12. A nut 14 is threadedly connected to the surface of the threaded rod 13, and a pressing plate 15 is fixedly connected to the front side of the surface of the nut 14.

[0029] Specifically, such as Figure 1 , Figure 3 As shown, a controller 16 is fixedly connected to the front side of the L-shaped bracket 12, and the controller 16 is electrically connected to the electric trolley 10 and the winding assembly 3.

[0030] In this embodiment: the nut 14 and the threaded rod 13 work together to allow the nut 14 to move smoothly under the constraint of the threaded rod 13, which in turn drives the pressing plate 15 to move, so that the pressing plate 15 contacts the wrapping film roll, thereby achieving rapid fixing of the wrapping film roll. At the same time, under the action of the controller 16, the operation of the electric trolley 10 and the winding assembly 3 can be precisely adjusted according to the actual situation. This not only smoothly drives the winding of the nonwoven fabric roll and the wrapping film, but also allows the electric trolley 10 to be started after the wrapping is completed, driving the cutting blade 11 to move, thereby achieving precise film cutting and improving the ease of use of the device.

[0031] Working principle: When packaging nonwoven fabric, first remove nut 14, insert the wrapping film roll into threaded rod 13, and then tighten nut 14 again. This will cause pressing plate 15 to press against the film roll, achieving rapid fixation of the wrapping film roll. After fixing the wrapping film roll, manually tighten bolt 308 to release the lock on moving ring 306, and then pass the nonwoven fabric roll through connecting rod 304. At the same time, adjust the spacing between clamping plates 307 according to the actual situation to fix nonwoven fabric rolls of specific specifications. Simultaneously, under the action of hydraulic cylinder 303, the moving plate 302 and connecting rod 304 can be vertically raised and lowered, so that the nonwoven fabric roll contacts the support roller 5, forming a low-friction rolling support to ensure the smooth rotation of the nonwoven fabric roll. After installation, the film threading stage begins, and the film roll is manually moved... Pressing roller 205 drives slider 204 to move smoothly under the constraint of positioning rod 203 and compress spring 206, releasing the restriction effect of limiting component 2, allowing the stretch film to pass through limiting component 2 and adhere to the non-woven fabric roll. After the stretch film is in place, spring 206 drives slider 204 to reset, so that the stretch film is dynamically clamped between pressing roller 205 and support roller 207. Then, the operator sets the operating parameters of electric trolley 10 and winding component 3 through controller 16, starts rotating motor 305 to drive non-woven fabric roll to wind up, and synchronously completes the wrapping of stretch film. After the operation is completed, start electric trolley 10 to drive cutting blade 11 to move smoothly and complete precise film cutting, avoiding problems such as rough edges and tears, and providing reliable guarantee for continuous packaging.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
