Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam mattress production, specifically a foam mattress winding device. Background Technology
[0002] Foam mattresses are a widely used type of mattress, with foam as their primary material. Foam is made from wood cellulose fibers or foamed plastic polymers and has a porous honeycomb structure, giving it softness, absorbency, and good elasticity. Foam mattresses can be categorized based on the type of foam used, such as memory foam mattresses, polyurethane foam mattresses, and high-resilience foam mattresses. Memory foam mattresses are particularly popular because they conform to the body's curves and distribute pressure effectively. The advantages of foam mattresses include their softness and comfort, providing excellent support, and ease of folding and storage, making them suitable for homes with limited space or those requiring frequent movement. Foam mattresses require a rolling mechanism during production.
[0003] For example, authorization announcement number CN213923342U discloses a sponge winding device. This utility model relates to the field of sponge production technology and includes a support base, a limiting plate, and a winding drum. A drive shaft is provided on the support base, and the drive shafts are symmetrically arranged. One end of each drive shaft is fixedly connected to a snap-fit component, and the other end of the drive shaft is snap-fitted to the side wall of the limiting plate via the snap-fit component. One side wall of one of the limiting plates has an installation groove, and a snap-fit mechanism is provided on the peripheral side wall of the installation groove. A clamping mechanism is rotatably connected to the inner side wall of the bottom end of the installation groove. A cross-shaped snap-fit groove is provided on the side wall of the other limiting plate. This sponge winding device improves the working efficiency of the winding device.
[0004] However, the above-mentioned technology requires disassembling the winding drum after the sponge is rolled up to unload the sponge, which is quite troublesome. In addition, the sponge is relatively fluffy, and the volume is large after being directly rolled up by the winding drum, which is not convenient for transportation. Therefore, the market urgently needs to develop a sponge mattress winding device to help people solve the existing problems. Utility Model Content
[0005] The purpose of this utility model is to provide a foam mattress winding device to solve the problem mentioned in the background art that the existing technology requires disassembling the winding drum after the foam is wound onto it, which is quite troublesome. In addition, the foam is relatively fluffy, and the volume is large after being directly wound onto the winding drum, which is inconvenient for transportation.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a foam mattress winding device, comprising a base plate, a vertical support plate fixedly connected to the rear end of the upper end of the base plate, a limiting tube fixedly connected to the upper middle part of the vertical support plate, a rotating shaft rotatably connected inside the limiting tube, a rotating rod fixedly connected to the front end of the rotating shaft extending out of the front end of the limiting tube, a winding rod fixedly connected to both the upper and lower ends of the front end of the rotating rod, a material ejection ring provided on the outer side of the rotating rod, and transverse support plates fixedly connected to both the upper and lower ends of the material ejection ring on the front end surface of the vertical support plate, with arc-shaped pressure plates connected to the inner sides of both transverse support plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) In this utility model, by designing a retractable arc-shaped pressure plate structure driven by a hydraulic rod, the mattress can be squeezed in real time during the rolling process of the foam mattress. Specifically, after the telescopic end of the hydraulic rod passes through the transverse support plate, it is fixedly connected to the outer end face of the arc-shaped pressure plate. When rolling, the hydraulic rod extends and pushes the arc-shaped pressure plate to retract inward, squeezing the upper and lower ends of the foam mattress that is being rolled, thereby effectively reducing the volume of the mattress after rolling and making it more compact. This design facilitates subsequent packaging, storage and transportation, reduces logistics costs and improves space utilization.

This design simplifies the operation process, saves labor costs, and also improves production efficiency.
[0016] (3) In this utility model, the rotating roller structure set on the arc-shaped pressure plate effectively reduces the friction between the mattress and the pressure plate during the winding process. The rotating roller and the arc-shaped pressure plate are connected by a fixed shaft. During winding, the rotating roller contacts the sponge mattress and rotates, thereby avoiding damage to the mattress surface caused by friction. Attached Figure Description

Detailed Implementation
[0022] 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.
[0023] Please see Figure 1-4This utility model provides an embodiment of a foam mattress winding device, including a base plate 1. A vertical support plate 101 is fixedly connected to the rear end of the upper end of the base plate 1. A limiting tube 102 is fixedly connected to the upper middle part of the vertical support plate 101. A rotating shaft 2 is rotatably connected inside the limiting tube 102. The front end of the rotating shaft 2 extends out of the front end of the limiting tube 102 and is fixedly connected to a rotating rod 201. Both the upper and lower ends of the front end of the rotating rod 201 are fixedly connected to winding rods 202. A driving device 3 is fixedly installed at the upper middle part of the rear end face of the vertical support plate 101. A motor 301 is fixedly installed inside the driving device 3. The rear end of the rotating shaft 2 extends into the driving device 3 and is fixedly connected to the output shaft of the motor 301. The motor 301 drives the rotating shaft 2 to rotate, which in turn drives the rotating rod 201 and the two winding rods 202 on it to rotate. When winding the foam mattress, one end of the foam mattress is inserted between the two winding rods 202, so that the two winding rods 202 pull the foam mattress to wind it up when they rotate.
[0024] Please see Figure 2-3 Hydraulic rods 501 are fixedly installed at the middle of the outer end faces of the two transverse support plates 5. The telescopic ends of the two hydraulic rods 501 pass through the middle of the two transverse support plates 5 and are fixedly connected to the middle of the outer end faces of the two arc-shaped pressure plates 6. Guide tubes 502 are fixedly connected to both sides of the middle of the rear end faces of the two transverse support plates 5. Guide rods 603 are fixedly connected to both sides of the middle of the rear end faces of the two arc-shaped pressure plates 6. The guide rods 603 on the two arc-shaped pressure plates 6 pass through the interior of the guide tubes 502 on the two transverse support plates 5. Rotating rollers 601 are rotatably connected to both sides of the arc-shaped pressure plates 6. The rotating rollers 601 and the arc-shaped pressure plates 6 are rotatably connected to the arc-shaped pressure plates 6. The curved pressure plates 6 are rotatably connected by a fixed shaft 602. When the two winding rods 202 rotate and pull the foam mattress to roll it up, the two hydraulic rods 501 push the two curved pressure plates 6 to close, squeezing the upper and lower ends of the rolled foam mattress, causing the foam mattress to shrink and reducing its volume. When the curved pressure plates 6 close, they are guided by the guide rods 603 sliding along the inside of the guide tube 502 to ensure the stability of the movement of the curved pressure plates 6. At the same time, the rotating rollers 601 rotate when in contact with the foam mattress, so that the foam mattress reduces the friction with the edge of the curved pressure plates 6 when it is rolled up and rotated, preventing damage to the foam mattress.
[0025] Please see Figure 2-4A material ejection ring 4 is provided on the outer side of the rotating rod 201. Horizontal support plates 5 are fixedly connected to the front end of the vertical support plate 101 at both the upper and lower ends of the material ejection ring 4. Arc-shaped pressure plates 6 are connected to the inner sides of the two horizontal support plates 5. Electrically controlled telescopic rods 401 are fixedly provided on the rear end of the vertical support plate 101 on both sides of the limiting tube 102. The telescopic ends of the two electrically controlled telescopic rods 401 pass through the vertical support plate 101 and are fixedly connected to the rear end of the material ejection ring 4 on both sides. When the sponge mattress is rolled up, a plastic film bag is placed on the outside of the two arc-shaped pressure plates 6. The two arc-shaped pressure plates 6 open the plastic film bag. The two electrically controlled telescopic rods 401 push the material ejection ring 4 synchronously, causing the material ejection ring 4 to push the rolled-up sponge mattress forward into the plastic film bag, achieving synchronous bagging after rolling up and improving production efficiency.
[0026] Working Principle: In use, first insert one end of the foam mattress between the two winding rods 202. Then, start the motor 301. The output shaft of the motor 301 drives the rotating shaft 2 to rotate inside the limiting tube 102, thereby causing the rotating rod 201 and the winding rods 202 at its upper and lower ends to rotate synchronously, starting to pull the foam mattress to wind it up. During the winding process, the two hydraulic rods 501 extend synchronously, pushing the two arc-shaped pressure plates 6 inward to compress the upper and lower ends of the winding foam mattress, reducing its volume and making it more compact. Simultaneously, as the arc-shaped pressure plates 6 move, the guide rods 603 on them slide along the inside of the guide tube 502, ensuring the stability of the arc-shaped pressure plates 6's movement. The rotating rollers 601 on both sides of the arc-shaped pressure plates 6 rotate with the foam mattress upon contact, reducing friction with the edges of the foam mattress and preventing damage. After the foam mattress is rolled up, the plastic film bag is placed over the outside of the two arc-shaped pressure plates 6. Then, the two electrically controlled telescopic rods 401 extend synchronously, pushing the unloading ring 4 forward. The unloading ring 4 then pushes the rolled-up foam mattress into the plastic film bag, achieving synchronous bagging and greatly improving production efficiency.
