Description

Technical Field

[0001] The utility model relates to a fabric composite device, in particular to a composite molding device for radiation-proof composite fabrics. Background Art

[0002] In some special locations, high levels of radiation are generated, such as near high-power communications equipment, CT / MRI equipment, and certain specialized military environments. Prolonged exposure to high-intensity, high-dose radiation can cause irreversible damage to the human body. To protect the health and safety of workers in these settings, radiation-resistant clothing has been developed. These garments are made of radiation-resistant fabrics. This fabric significantly reduces the amount of electromagnetic radiation passing through, ensuring wearer safety at work.

[0003] Existing radiation-proof fabrics primarily rely on metal shielding to achieve their radiation protection. Specifically, these fabrics utilize a variety of materials and processes to achieve this shielding effect, including metal fiber blends, metal micromesh structures, and metal coating technologies. Compared to the first two processes, metal-coated fabrics offer better protection, but they also offer lower breathability and are difficult to clean and maintain. Therefore, the first two methods, particularly metal fiber blends, are more commonly used in practice.

[0004] However, because the surface feel of these fabrics is less comfortable than that of ordinary fabrics, a fabric lamination process is often used to bond ordinary fabrics with metal fiber blends to increase wearing comfort. Existing adhesive lamination equipment generally applies too much glue, which not only makes the finished composite fabric feel harder, but also easily causes glue to bleed through the edges of the fabric during production, resulting in low glue utilization and increased glue costs. Summary of the Invention

[0005] The utility model provides a composite molding device for radiation-proof composite fabrics, which solves the problem in the prior art that the amount of glue applied is generally too much.

[0006] The above technical problems of the present invention are mainly solved by the following technical solutions: a composite molding device for radiation-proof composite fabrics, comprising a first introduction roller, a glue roller, a bearing roller, a second introduction roller and a pressing roller group, wherein the bearing roller is located below the glue roller and abuts against each other, and the bearing roller and the glue roller rotate synchronously in opposite directions, and the glue roller comprises a core shaft and a hollow roller coaxially fixed relative to the core shaft, and a plurality of ribs and sleeves are provided inside the hollow roller, the ribs are connected and fixed between the sleeves and the hollow roller, and the sleeves are fixedly sleeved on the core shaft, and a guide port is provided on the ribs and close to the side of the hollow roller, one end of the hollow roller is sealed with a sealing plate, and the other end is provided with an annular baffle, and the annular baffle An annular opening is formed between the sleeve and the upper glue roller, and a glue replenishing nozzle extending into the annular opening is fixed to one end of the upper glue roller, and the glue replenishing nozzle can replenish glue into the hollow drum; a number of pressure control mechanisms are densely distributed on the hollow drum, and the pressure control mechanism includes an elastic member, a plug, a touch head and a glue overflow port, and the glue overflow port is provided on the hollow drum and passes through inside and outside, and the pressure control mechanism is located as a whole inside the hollow drum, one end of the elastic member is fixed to the inner wall of the hollow drum, and the other end is connected and fixed to the plug, and the touch head is fixed to the plug, and the elastic member can push the plug to abut against the inner end of the glue overflow port, and the touch head passes through the glue overflow port and protrudes from the outer end portion of the glue overflow port.

[0007] The first inlet roller is used to introduce the first fabric, and the second inlet roller is used to introduce the second fabric. The first fabric also flows through the upper glue roller and the supporting roller. The pressure control mechanism on the upper glue roller has the function of controlling the glue discharge. When the touch head contacts the fabric, the touch head will drive the plug to retract inward as a whole. At this time, the overflow port loses its blockage, and the glue in the hollow drum flows out of the overflow port under the action of gravity, forming glue dots on the fabric. Then, when the touch head turns away from the fabric, the plug re-seals the overflow port under the action of the elastic member to prevent further glue discharge from the overflow port. At the same time, the inner cavity of the hollow drum is connected to the guide port, so that the glue inside the rotating hollow drum will continue to flow under the action of gravity and remain in the bottom area during rotation. The function of the annular baffle is to block the glue and prevent it from overflowing. The glue replenishing nozzle is used to replenish the glue.

[0008] The utility model utilizes the above-mentioned technical solution to effectively control the amount of glue delivered by the glue roller, distributing the glue evenly on the fabric in a dotted pattern. The glue is then pressed together by the pressing rollers, bonding the two fabrics together. This method of gluing not only effectively reduces glue consumption but also significantly improves the fabric's feel. Glue is virtually eliminated from the edges of the composite fabrics, helping to keep the equipment clean and preventing a significant decrease in the bonding strength of the fabrics.

[0009] Furthermore, a guide tile is fixed to one end of the upper glue roller near the annular opening. The guide tile is composed of a fixed plate, an oblique baffle, a guide plate, and an inner baffle. The guide plate and the inner baffle are located on the inner side of the annular baffle, and the cross-section of the guide plate is an inverted arc. During the rotation process, the annular baffle located on the upper side is likely to produce glue dripping downwards. This glue will drip onto the core shaft or the annular baffle below, which will easily cause glue to flow out. This not only causes glue waste, but also contaminates the machine body and even the fabric. To this end, the utility model sets a guide tile to guide the flow of dripping glue, causing it to drip from the open space on both sides of the core shaft, avoiding the core shaft and the annular baffle below.

[0010] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention can effectively control the amount of glue output by the glue roller, and the glue is evenly distributed on the fabric in a dotted shape, which not only effectively reduces the consumption of glue, but also significantly improves the feel of the fabric. There is almost no glue output at the composite edges of the fabric, which is beneficial to keeping the equipment clean, and the bonding strength of the fabric will not be significantly reduced; 2. The present invention guides the flow of dripping glue by setting guide tiles, so that it drips from the open space on both sides of the core shaft, avoiding the core shaft and the annular baffle below, to prevent the glue from flowing out or contaminating the machine body.

[0019] The first inlet roller is used to introduce the first fabric, and the second inlet roller is used to introduce the second fabric. The first fabric also flows through the upper glue roller and the supporting roller. The pressure control mechanism on the upper glue roller has the function of controlling the glue discharge. When the touch head contacts the fabric, the touch head will drive the plug to retract inward as a whole. At this time, the overflow port loses its blockage, and the glue in the hollow drum flows out of the overflow port under the action of gravity, forming glue dots on the fabric. Then, when the touch head turns away from the fabric, the plug re-seals the overflow port under the action of the elastic member to prevent further glue discharge from the overflow port. At the same time, the inner cavity of the hollow drum is connected to the guide port, so that the glue inside the rotating hollow drum will continue to flow under the action of gravity and remain in the bottom area during rotation.

[0020] This embodiment utilizes the above-mentioned technical solution to effectively control the amount of glue dispensed by the glue roller, distributing the glue evenly across the fabric in a dotted pattern. The glue is then pressed together by the laminating rollers, bonding the two fabrics together. This gluing method not only effectively reduces glue consumption but also significantly improves the fabric's feel. Glue leakage is virtually eliminated from the edges of the composite fabrics, keeping the equipment clean and preventing a significant decrease in the bonding strength of the fabrics.

The guide tile is composed of a fixed plate 51, an oblique baffle 52, a guide plate 53, and an inner baffle 54. The guide plate and the inner baffle are located on the inner side of the annular baffle, and the cross-section of the guide plate is an inverted arc. During the rotation process, the annular baffle on the upper side is likely to produce glue dripping downwards. This glue will drip onto the core shaft or the annular baffle below, which will easily cause glue to flow out. This not only causes glue waste, but also contaminates the machine body and even the fabric. To this end, this embodiment sets a guide tile to guide the flow of dripping glue, so that it drips from the open space on both sides of the core shaft, avoiding the core shaft and the annular baffle below.

[0023] See Figure 4 A rubber retaining ring 141 is also provided on the shaft sleeve located on one side of the annular baffle. The glue will flow onto the shaft sleeve through the ribs and overflow to the outside. The rubber retaining ring can avoid this situation.

All such modifications obvious to those skilled in the art are intended to be included within the scope of the present claims.
