Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric roll support technology, and in particular to a nonwoven fabric roll support. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth or needle-punched cotton, is a new generation of environmentally friendly material composed of oriented or randomly arranged fibers. It features moisture resistance, breathability, flexibility, lightweight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability. These properties make non-woven fabrics widely used in various fields, such as sound and heat insulation materials, heating elements, masks, clothing, medical materials, and filling materials.

[0003] Existing nonwoven fabric roll supports are used by simply hanging the nonwoven fabric roll on the support. However, the diameter of the support shaft on the existing nonwoven fabric roll supports is usually smaller than the inner diameter of the nonwoven fabric roll. Therefore, when the nonwoven fabric roll rotates at a high speed, the nonwoven fabric roll is not stable enough on the nonwoven fabric roll support and will wobble. Utility Model Content

[0004] The purpose of this invention is to provide a nonwoven fabric roll support to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a non-woven fabric roll support, comprising a mounting plate, a support frame fixedly mounted on one side of the mounting plate, a support shaft fixedly mounted on the support frame, a non-woven fabric roll mounted on the support shaft, a limit frame provided at the top of the support shaft, a roller rotatably mounted inside the limit frame, a connecting plate fixedly mounted at the top of the limit frame, the connecting plate being slidably connected to the mounting plate, and a limiting mechanism being provided between the connecting plate and the mounting plate.

[0006] As a further description of the above technical solution: a retaining strip is fixedly installed at the bottom of the connecting plate, and first sliding rods are fixedly installed on both sides inside the mounting plate. The two ends of the retaining strip are respectively slidably engaged with the two first sliding rods. A tension spring is sleeved on the outside of the two first sliding rods. The top ends of the two tension springs are respectively fixedly connected to the bottom ends of the retaining strip, and the bottom ends of the two tension springs are fixedly connected to the inside of the mounting plate.

[0007] As a further description of the above technical solution: the limiting mechanism includes two locking blocks, both of which are slidably installed inside the mounting plate. Each of the two locking blocks has multiple slots on the side near the locking strip, and the slots are adapted to the two ends of the locking strip. Each of the two locking blocks has a connecting post fixedly installed on the side away from the locking strip. A limiting post is slidably installed on the connecting post, and the limiting post is fixedly installed on the inner wall of the mounting plate. A first spring is fixedly installed between the connecting post and the inner wall of the mounting plate, and the limiting post is disposed inside the first spring.

[0008] As a further description of the above technical solution: a drive plate is slidably mounted on the side wall of the mounting plate, and drive grooves are provided on both sides of the top of the drive plate. Drive rods are fixedly mounted on the top of the two locking blocks. The two drive rods pass through the side wall of the mounting plate and slide in cooperation with the side wall of the mounting plate. The top opening of the drive groove is located directly below the drive rod. A push rod is fixedly mounted on the bottom of the drive plate, and a second slide rod is fixedly mounted on the bottom of the mounting plate. The second slide rod slides in cooperation with the push rod. A second spring is fixedly connected between the push rod and the bottom of the mounting plate. The second spring is located outside the second slide rod.

[0009] As a further description of the above technical solution: support pads are fixedly installed at the four corners of the side wall of the mounting plate near the drive plate.

[0010] As a further description of the above technical solution: each of the four corners of the mounting plate is provided with a fixing bolt, and one end of each of the four fixing bolts penetrates through the mounting plate and the side wall of the support pad.

[0011] This utility model provides a nonwoven fabric roll support. It has the following advantages: When using this device, the limiting frame is moved to its highest position, and the nonwoven fabric roll is placed on the support shaft. Under the action of the connecting plate and the tension spring, the limiting frame presses against the nonwoven fabric roll. The roller inside the limiting frame contacts the nonwoven fabric roll. During the use of the nonwoven fabric roll, the roller remains in contact with the nonwoven fabric roll under the action of the tension spring, ensuring the stability of the nonwoven fabric roll during rotation. Simultaneously, the limiting mechanism locks the connecting plate, preventing it from moving upwards and allowing only downward movement. This avoids excessive rotation of the nonwoven fabric roll, which could lift the roller and the limiting frame, ensuring the stability of the nonwoven fabric roll during rotation.

[0012] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0013] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5A nonwoven fabric roll support includes a mounting plate 1, a support frame 2 fixedly mounted on one side of the mounting plate 1, a support shaft 3 fixedly mounted on the support frame 2, a nonwoven fabric roll 4 mounted on the support shaft 3, a limit frame 5 at the top of the support shaft 3, a roller (not shown in the figure) rotatably mounted inside the limit frame 5, a connecting plate 6 fixedly mounted at the top of the limit frame 5, the connecting plate 6 being slidably connected to the mounting plate 1, and a limiting mechanism being provided between the connecting plate 6 and the mounting plate 1; when using this device, the limit frame 5 is moved to its highest position, and... The nonwoven fabric roll 4 is placed on the support shaft 3. The limiting frame 5 is pressed against the nonwoven fabric roll 4 under the action of the connecting plate 6 and the tension spring 9. The roller inside the limiting frame 5 is in contact with the nonwoven fabric roll 4. During the use of the nonwoven fabric roll 4, the roller is always in contact with the nonwoven fabric roll 4 under the action of the tension spring 9, ensuring the stability of the nonwoven fabric roll 4 when rotating. At the same time, the connecting plate 6 is locked by the limiting mechanism, so that the connecting plate 6 can only move down and cannot move up, to prevent the nonwoven fabric roll 4 from rotating too much and lifting the roller and the limiting frame 5, thus ensuring the stability of the nonwoven fabric roll 4 when rotating.

[0023] As a preferred embodiment, a retaining strip 7 is fixedly installed at the bottom of the connecting plate 6, and first sliding rods 8 are fixedly installed on both sides of the interior of the mounting plate 1. The two ends of the retaining strip 7 are slidably engaged with the two first sliding rods 8 respectively. Tension springs 9 are sleeved on the outside of the two first sliding rods 8. The top ends of the two tension springs 9 are fixedly connected to the bottom ends of the retaining strip 7 respectively, and the bottom ends of the two tension springs 9 are fixedly connected to the interior of the mounting plate 1. In use, the elastic force of the two tension springs 9 drives the retaining strip 7 and the connecting plate 6 to descend, so that the limiting frame 5 and the roller are always in close contact with the non-woven fabric roll 4.

[0024] As a preferred embodiment, the limiting mechanism includes two locking blocks 10, both of which are slidably installed inside the mounting plate 1. Each locking block 10 has multiple slots 11 on its side near the locking strip 7, the slots 11 being adapted to both ends of the locking strip 7. A connecting post 12 is fixedly installed on the side of each locking block 10 away from the locking strip 7. A limiting post 13 is slidably installed on the connecting post 12, and the limiting post 13 is fixedly installed on the inner wall of the mounting plate 1. The connection post 12 is positioned between the connecting post 12 and the inner wall of the mounting plate 1. A first spring 14 is fixedly installed, and the limiting post 13 is set inside the first spring 14; both ends of the locking strip 7 are provided with inclined surfaces, and the inclined surfaces face downwards. The top of both ends of the locking strip 7 is flat. The locking groove 11 is adapted to both ends of the locking strip 7. Therefore, when the locking strip 7 moves downwards, it will push the two locking blocks 10 to both ends. When the locking strip 7 reaches the next locking groove 11 position, the two locking blocks 10 are reset under the action of the first spring 14, clamping the locking strip 7 in the middle. Since the top of both ends of the locking strip 7 is set as a flat surface, the locking strip 7 cannot move upwards under the clamping of the two locking blocks 10.

[0025] As a preferred embodiment, a drive plate 15 is slidably mounted on the side wall of the mounting plate 1. Drive slots 16 are provided on both sides of the top of the drive plate 15. Drive rods 17 are fixedly mounted on the top of each of the two locking blocks 10. The two drive rods 17 penetrate the side wall of the mounting plate 1 and slide in cooperation with it. The top opening of the drive slots 16 is located directly below the drive rods 17. A push rod 18 is fixedly mounted on the bottom of the drive plate 15. A second sliding rod 19 is fixedly mounted on the bottom of the mounting plate 1. The second sliding rod 19 slides in cooperation with the push rod 18. The push rod 18 and the mounting plate 1... A second spring 20 is fixedly connected between the bottoms, and the second spring 20 is set outside the second slide rod 19. After the non-woven fabric on a non-woven fabric roll 4 is completely consumed, the non-woven fabric needs to be replaced. At this time, push the push rod 18, and the push rod 18 drives the drive plate 15 to rise, so that the two drive rods 17 enter the drive groove 16. The two drive rods 17 drive the two locking blocks 10 away from each other along the trajectory of the drive groove 16, so that the locking strip 7 disengages from the locking groove 11 on the two locking blocks 10, push the limiting frame 5 and the roller to the top, and then place the new non-woven fabric roll 4 on the support shaft 3, and then release the push rod 18.

[0026] As a preferred technical solution in this embodiment, support pads 21 are fixedly installed at the four corners of the side wall of the mounting plate 1 near the drive plate 15; the support pads 21 ensure that there is a certain gap between the mounting plate 1 and the mounting plane, thus ensuring the normal movement of the drive plate 15.

[0027] As a preferred technical solution in this embodiment, the mounting plate 1 is provided with fixing bolts 22 at each of its four corners, and one end of each of the four fixing bolts 22 penetrates the mounting plate 1 and the side wall of the support pad 21; the mounting plate 1 is installed by fixing bolts 22.
