Description

Technical Field

[0001] The utility model relates to the field related to the processing of child safety seat cloth covers, in particular to a pattern stamping device for child safety seat cloth covers. Background Art

[0002] Child seats, also known as child restraint systems, are designed for children of different ages (or weights) and installed in cars to effectively improve the safety of children riding in cars. Child seats are usually covered with cloth covers to improve seat comfort, and during processing, the cloth covers need to be embossed with logos or patterns.

[0003] The pattern imprinting device processes a hard stamping blank into a stamping die; then spin-coats a polymer film on the substrate, puts it into the stamping machine for heating and presses the stamping die onto the polymer film on the substrate, then lowers the temperature to near the solidification point of the polymer and separates the stamping die from the polymer layer, thus making a raised polymer pattern. The stamping die is usually made of materials such as Si, SiO2, silicon nitride, and diamond; first, the hard material for the stamping die is made into a flat sheet blank, then a layer of electron beam exposure resist is spin-coated on the blank, and a nano pattern is engraved by electron beam lithography, and then conventional pattern transfer techniques such as etching and stripping are used to convert the pattern on the blank into a pattern of the hard material.

[0004] Since the polymer film is heated unidirectionally, it will cool down when it contacts the cloth cover. Even if the temperature needs to be lowered during embossing, the temperature effect when contacting the cloth cover is uncontrollable, which may cause the local temperature to drop to near the solidification point of the polymer. When the temperature is subsequently lowered, the embossed pattern on the child safety seat cloth cover will solidify at different time points, causing the embossed pattern to become mottled. Utility Model Content

[0005] The utility model aims to provide a pattern stamping device for a child safety seat cloth cover, so as to solve the problem raised in the above-mentioned background technology that since the polymer film is heated in one direction, it will cool down when it contacts the cloth cover. Even if it needs to be cooled down during stamping, the temperature influence when contacting the cloth cover is uncontrollable, which may cause the local temperature to drop to near the solidification point of the polymer. When the temperature is subsequently lowered, the stamped pattern on the child safety seat cloth cover solidifies at different time points, making the stamped pattern mottled.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pattern stamping device for a child safety seat cloth cover, comprising an operating table, a first driving cylinder is installed in the middle of the lower end of the operating table, a supporting platform is fixed to the upper end of the operating table along the output rod end of the first driving cylinder, a heating zone is arranged in the middle of the upper end surface of the supporting platform, a supporting upright is fixed in the middle of the front and rear ends of the upper end of the operating table, a stamping unit and a stamping assembly are arranged on the upper end of the operating table, the stamping unit comprises a fixed top plate, the upper ends of the two supporting uprights are fixed to the fixed top plate, a second driving cylinder is installed in the middle of the upper end of the fixed top plate, a fixing assembly is arranged at the lower end of the fixed top plate, the fixing assembly is composed of an upper fixing plate and a heating mold, the upper fixing plate is located at the upper end of the heating mold, the output rod end of the second driving cylinder is fixed to the upper fixing plate, and the stamping assembly comprises a C-shaped stamping mold, and the C-shaped stamping mold is located outside the heating mold.

[0007] Preferably, side rectangular grooves are opened in the middle of the two side surfaces of the upper fixed plate, side mounting plates are integrally connected to the two sides of the C-shaped die, side elastic blocks are fixed in the middle of the two sides of the upper end of the side mounting plate, and the upper end of the side elastic block is integrally connected to a triangular support column, and the right-angle surface of the triangular support column is inserted into the upper end of the side rectangular groove and fits with the upper end surface of the upper fixed plate.

[0008] Preferably, first conveying rollers are rotatably connected to both sides of the operating table via bearings, and an intermediate merging area is formed between the two first conveying rollers on each side.

[0009] Preferably, a second conveying roller is rotatably connected to the operating table along the outer side of the first conveying roller via a bearing, three second conveying rollers are arranged on each side, and a conveying area is formed between two upper and lower adjacent second conveying rollers.

[0010] Preferably, fixing grooves are formed through the upper end surface of the upper fixing plate along both sides of the heating mold, and mounting holes are formed through the front and rear ends of the upper end surface of the side mounting plate, the mounting holes correspond to the fixing grooves, and the side mounting plate and the upper fixing plate are fixed by locking the nuts of the bolts after the screw ends of the bolts pass through the fixing grooves and the mounting holes.

[0011] Preferably, two ends of the upper end of the upper fixed plate are fixed with limiting lifting rods, and the limiting lifting rods slide along the fixed top plate.

[0012] Preferably, a supporting frame is welded and fixed to the lower end of the operating table.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, before stamping, the heating zone on the support platform and the heating mold on the fixed component are controlled to preheat; when the fabric and the stamping film reach the upper end of the support platform, the first driving cylinder drives the support platform to move upward until the support platform contacts the lower end surface of the fabric, and the second driving cylinder drives the fixed component and the stamping component to move downward for stamping. Since the upper and lower ends of the overall structure of the fabric and the stamping film are provided with heating structures, and the downward stroke of the second driving cylinder is greater than the upward stroke of the first driving cylinder, the heating of the fabric position is longer than that of the stamping film, and the temperature of the fabric and the stamping film is relatively uniform during subsequent stamping, which solves the problem that the polymer film is heated in one direction and will cool down when it contacts the cloth cover. Even if it needs to cool down during stamping, the temperature effect when it contacts the cloth cover is uncontrollable, which may cause the local temperature to drop to near the solidification point of the polymer. During the subsequent cooling, the stamping pattern on the child safety seat cloth cover solidifies at different time points, making the stamping pattern flowery.

[0015] 2. In the utility model, the cloth for preparing the cloth cover of the child safety seat enters through the conveying area between the two second conveying rollers at the lower end of one side, and the embossed film enters through the conveying area between the two second conveying rollers at the upper end of one side. The cloth and the embossed film reach the upper end of the support platform through the first conveying roller and the middle merging area, and are then conveyed through the first conveying roller on the other side. The cloth and the embossed film are respectively pulled out through the two conveying areas between the three second conveying rollers, so that the cloth and the embossed film are separated, and the cloth can be directly conveyed to the next processing step, thereby reducing the re-separation step and reducing the processing time of the entire cloth cover.

[0016] 3. In the utility model, the stamping assembly moves upward from the lower end of the heating mold, and the triangular support column deforms outward when it contacts the side rectangular groove until the stamping assembly is inserted into the fixing assembly. The triangular support column is reset and clamped on the upper end of the upper fixing plate. It is temporarily fixed in this state, and subsequent fixing with bolts does not require the assistance of other staff, thereby reducing manpower consumption. BRIEF DESCRIPTION OF THE DRAWINGS
