Description

Technical Field

[0001] This utility model belongs to the field of latex pillow drying technology, specifically a latex pillow drying device. Background Technology

[0002] In recent years, with consumers placing greater emphasis on sleep health, the market demand for latex pillows has exploded due to their excellent elastic support, breathability, moisture resistance, and antibacterial properties. To meet the demands of large-scale production, latex pillow production lines need to transform from "semi-automatic, decentralized processing" to "continuous and efficient" processes. The drying process, as a core step in latex pillow production (directly affecting product quality and production cycle), makes the optimization of its equipment a key breakthrough for companies to increase production capacity.

[0003] Meanwhile, a drying device for latex pillow production and processing, with application number CN202120228126.X, includes a cabinet. A heating layer is installed on the inner wall of the cabinet. Fan frames are embedded in both sides of the bottom of the inner wall of the cabinet. An electric fan is installed at the bottom of the inner wall of each fan frame. Slots are opened on both sides of the bottom of each fan frame. A cabinet door is hinged to the front of the cabinet. A handrail is bolted to the front of the cabinet door. A horizontal plate is bolted between the two sides of the inner wall of the cabinet. A through hole is opened inside the horizontal plate. A filter plate is slidably connected to the top of the cabinet. A housing is bolted to the back of the cabinet. A return spring is engaged on the right side of the inner wall of the housing. A locking block is engaged at the left end of the return spring, and the left end of the locking block engages with the back of the filter plate. A push block is bolted to the back of the locking block, which penetrates the back of the housing.

[0004] However, the following problems were found in the implementation of the relevant technology: There is no moisture pretreatment step. The initial moisture content of the latex pillow after molding is high. When it enters the drying room directly, a large amount of free moisture needs to be removed by high-temperature evaporation. The evaporation rate is slow and the drying time for a single batch is long, resulting in low efficiency and high energy consumption. In addition, there is no flipping design. The pillows need to be manually flipped and sent back into the drying room, which not only interrupts the production process, but also makes it easy for the pillow position to shift due to operational errors, further reducing the drying efficiency.

[0005] Therefore, we propose a latex pillow drying device. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a latex pillow drying device, which has the advantages of squeezing out some moisture before entering the drying chamber, reducing the initial moisture content entering the drying zone, and simultaneously achieving secondary drying by flipping the pillow after drying on one side and turning it so that the other side faces upward.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a latex pillow drying device, including a conveying mechanism, a pressing mechanism, and a flipping mechanism; the conveying mechanism includes two sets of wide conveying rollers and one set of narrow conveying rollers, each set of wide conveying rollers being provided with a drying chamber; the pressing mechanism includes a support plate, a first motor is fixedly connected to the lower surface of the support plate, a lead screw is fixedly connected to the output end of the first motor, a threaded block is threadedly connected to the lead screw, a fixing block is fixedly connected to the lower surface of the support plate, a telescopic connecting rod is installed on the fixing block and the threaded block, a mounting frame is installed at the other end of the telescopic connecting rod, and a pressure roller is rotatably connected inside the mounting frame; the flipping mechanism includes a support base, a second motor is fixedly connected to the outer surface of the support base, a rotating rod is fixedly connected to the output end of the second motor, a flipping frame is fixedly connected to the outer surface of the rotating rod, and the flipping frame is provided with multiple slots.

[0008] Preferably, the narrow conveyor roller is positioned between two wide conveyor rollers, and the top surfaces of the narrow conveyor roller and the wide conveyor roller are at the same height.

[0009] Preferably, the width of the wide conveyor roller is greater than that of the latex pillow, and the width of the narrow conveyor roller is less than that of the latex pillow.

[0010] Preferably, the fixing block is rotatably connected to the lead screw.

[0011] Preferably, a sliding rod is fixedly connected to the outer surface of the fixing block, and the threaded block is slidably connected to the sliding rod.

[0012] Preferably, a telescopic bracket is fixedly connected to the lower surface of the support plate, and the other end of the telescopic bracket is fixedly connected to the mounting frame.

[0013] Preferably, the flipping mechanism is mounted on the side of the narrow conveyor roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the cooperation of a support plate, a first motor, a lead screw, a threaded block, a fixing block, a telescopic connecting rod, a mounting frame, and a pressure roller, squeezes out some of the moisture before entering the drying chamber, reducing the initial moisture content entering the drying zone. After the initial squeezing out of water, the remaining moisture per unit mass of pillow core is more easily evaporated, reducing the energy consumption per unit product and improving the thermal efficiency of the drying section. In addition, the height-adjustable pressure roller can avoid damage from excessive squeezing, while also avoiding excessive residual moisture caused by insufficient squeezing.

[0016] 2. This utility model, through the cooperation of a narrow conveyor roller, a second motor, a rotating rod, a flipping frame, and a slot, can flip the pillow after drying on one side and dry it again with the other side facing up. This achieves uniform moisture content on both sides of the pillow and from the surface to the deep layers, improving drying uniformity. At the same time, it can offset uneven stress, improve the regularity of the original shape of the pillow after drying, and avoid structural damage caused by shrinkage differences.

The pressure roller 11 is driven by a motor and gear set to convey and squeeze the latex pillow; the flipping mechanism includes a support base 12, a second motor 13 is fixedly connected to the outer surface of the support base 12, a rotating rod 14 is fixedly connected to the output end of the second motor 13, a flipping frame 15 is fixedly connected to the outer surface of the rotating rod 14, and a plurality of slots 16 are provided on the flipping frame 15. The narrow conveying roller 2 conveys a latex pillow into a slot 16, and then the flipping frame 15 rotates to convey another latex pillow into another slot 16, and so on. At the same time, while the flipping frame 15 is rotating, it flips the latex pillow and places it on the other side of the narrow conveying roller 2, and so on.

[0024] Specifically, the narrow conveyor roller 2 is positioned between the two wide conveyor rollers 1, and the top surfaces of the narrow conveyor roller 2 and the wide conveyor roller 1 are at the same height.

[0025] Furthermore, the width of the wide conveyor roller 1 is greater than that of the latex pillow, while the width of the narrow conveyor roller 2 is less than that of the latex pillow.

[0026] Furthermore, the fixing block 8 is rotatably connected to the lead screw 6 to support the lead screw 6.

[0027] It is worth noting that a slide rod 17 is fixedly connected to the outer surface of the fixed block 8, and the threaded block 7 is slidably connected to the slide rod 17 to prevent the threaded block 7 from rotating.

[0028] It is worth noting that a telescopic bracket 18 is fixedly connected to the lower surface of the support plate 4, and the other end of the telescopic bracket 18 is fixedly connected to the mounting bracket 10.

The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0031] Working principle: In use, the latex pillow is first conveyed on the first wide conveyor roller 1. Then, based on the thickness and height of the latex pillow, the first motor 5 on the support plate 4 drives the lead screw 6 to rotate. The threaded block 7 moves linearly on the lead screw 6 through the action of the thread, thereby adjusting the angle of the telescopic connecting rod 9. This causes the telescopic connecting rod 9 to extend out of the mounting frame 10, driving the mounting frame 10 and the pressure roller 11 to move, thus adjusting the height of the pressure roller 11. Then, the pressure roller 11 conveys and squeezes the moisture in the latex pillow through the previous wide conveyor roller 1, thereby reducing the moisture content of the latex pillow. One side of the pillow passes through the previous drying chamber 3 and is dried. Then, the latex pillow enters the narrow conveyor roller 2 and is conveyed by the narrow conveyor roller 2, which is narrower than the width of the latex pillow. The narrow conveyor roller 2 conveys the latex pillow into the slot 16 on the flipping frame 15. Then, the second motor 13 on the support base 12 drives the rotating rod 14 to rotate. The rotating rod 14 drives the flipping frame 15 to rotate. The rotation of the flipping frame 15 places the latex pillow on the other side of the flipping frame 15 and flips the latex pillow. Then, the flipped latex pillow is conveyed through another wide conveyor roller 1 to another drying chamber 3 to dry the other side, thus drying both sides of the latex pillow.
