Description
Technical Field
[0001] The utility model relates to the technical field of fabric pre-shrinking equipment, in particular to a fabric pre-shrinking machine with improved pre-shrinking effect. Background Art
[0002] A pre-shrinking machine is also called a shrink-proof machine; it is equipment for mechanical pre-shrinking finishing of fabrics; it means that under suitable wet and hot conditions, the weft density and radial shrinkage of the fabric are increased to a certain extent by the expansion and contraction deformation of an elastic blanket, so that the fabric has a loose structure. When the fibers are wetted and swollen, the radial length will no longer shorten, and the shrinkage rate of the finished product is significantly reduced. The pre-shrinking machine is divided into two types: the woolen blanket type pre-shrinking machine and the rubber blanket type pre-shrinking machine. The pre-shrinking machine is an essential pretreatment equipment for processing high-grade clothing, especially clothing with a large sewing shrinkage rate.
[0003] In the prior art, when the fabric is moved and conveyed in the pre-shrinking machine, due to the nature of the fabric itself, it will wrinkle and stack, resulting in the area being blocked unable to contact the steam, which will make the pre-shrinking effect poor and the appearance of the finished product unsatisfactory. In addition, the texture patterns of different fabrics are different, and a single steam direction may not work well when applied to some fabrics. Summary of the Utility Model
[0004] The utility model discloses a fabric pre-shrinking machine with improved pre-shrinking effect, aiming to solve the technical problems that when the fabric is moved and conveyed, it will wrinkle and stack, resulting in the area being blocked unable to contact the steam, and the texture patterns of different fabrics are different, and a single steam direction sometimes does not work well.
[0005] To achieve the above object, the utility model adopts the following technical solution: A fabric pre-shrinking machine with improved pre-shrinking effect, including a support frame, the top of the support frame is fixedly connected with a working box, a leveling operation module is arranged on the working box, and a blanking module is arranged below the working box. The leveling operation module includes a rotating shaft, and a circular hole one is opened at the top of the working box. The rotating shaft is movably connected in the circular hole one. The outer wall of the top end of the rotating shaft is fixedly connected with a gear one. The blanking module includes a slide rail, the slide rail is arranged below the working box, and a sliding table is slidably connected on the slide rail. The top of the working box is fixedly connected with a hydraulic rod, the driving end of the hydraulic rod is fixedly connected with a toothed rod, and the toothed rod meshes with the gear one. Two sliding grooves are opened on the inner wall of the top of the working box, and sliding frames are slidably connected in the two sliding grooves. The two sliding frames are centrosymmetric. The opposite sides of the two sliding frames are both fixedly connected with racks. The outer wall of the rotating shaft is fixedly connected with a gear two. Both racks mesh with the gear two. Circular holes two are opened on the two sliding frames, and fixing rods are fixedly connected in the two circular holes two. The outer parts of the two fixing rods are both movably connected with movable rollers. Ratch slots are opened on the two movable rollers, and fixing rings are fixedly connected to the outer walls of the two fixing rods. A plurality of elastic sheets arranged at equal circumferential intervals are fixedly connected to the outer walls of the two fixing rings. The plurality of elastic sheets all slide in the corresponding ratch slots. A circular hole three is opened on the working box, and a movable rod is movably connected in the circular hole three. The outer wall of the movable rod and the outer wall of the bottom end of the rotating shaft are both fixedly connected with bevel gears, and the two bevel gears mesh with each other. A fixing frame is fixedly connected to the outer wall of the movable rod, and a communicating chamber is fixedly connected to the bottom of the fixing frame. A plurality of circular holes four are opened at equal intervals at the bottom of the communicating chamber, and nozzles are fixedly connected in the plurality of circular holes four.
[0006] By setting up the leveling operation module, hot steam is introduced into the communicating chamber and sprayed out through the nozzles. At the same time, the hydraulic rod is started to reciprocally push and pull the toothed rod, driving the rotating shaft to rotate reciprocally. The movable rod is driven to rotate through the meshing of the two bevel gears, driving the nozzles to swing reciprocally, so that the steam can continuously contact the fabric from different angular directions, ensuring a good pre-shrinking effect when processing fabrics with different texture forms and improving applicability. At the same time, the two sliding frames slide towards each other reciprocally. When the movable rollers move towards the center, the elastic sheets slide in the ratch slots, and the movable rollers can rotate at the bottom of the fabric to ensure smooth movement. When the movable rollers move towards both sides, the elastic sheets will abut against the ratch slots to limit the rotation of the movable rollers, and the fabric is pulled towards both sides by the frictional force to keep it flat, avoiding wrinkling and stacking, which may cause the covered part of the fabric to not contact the steam, and improving the processing effect.
[0007] In a preferred embodiment, an installation frame is fixedly connected to the top of the support frame. Two circular holes five are provided on the installation frame. Rotating rods are movably connected in both of the two circular holes five. Conveyor rollers are fixedly connected to the outer walls of the two rotating rods. One side of the installation frame is fixedly connected with a motor, and the output end of the motor is fixedly connected to one end of the rotating rod located below. A collection box is arranged on the top of the sliding table, and a hydraulic cylinder is fixedly connected to the top of the slide rail. The driving end of the hydraulic cylinder is fixedly connected to the bottom of the sliding table.
[0008] By providing a blanking module, after the pre-shrinking process is completed, the fabric falls from the conveyor roller. At this time, the hydraulic cylinder is started to reciprocally push and pull the sliding table, driving the collection box to move reciprocally, so that the fabric is evenly stacked in the collection box, preventing the fabric from being randomly stacked and causing creases after being pressed for a long time, and ensuring the appearance and quality of the finished product.
[0009] As can be seen from the above, a fabric pre-shrinking machine with improved pre-shrinking effect provided by the present invention can keep the fabric flat through the leveling operation module while the fabric is being transported and processed, avoiding shrinkage and stacking of the fabric, so that the covered part of the fabric cannot contact the steam. At the same time, the steam can continuously contact the fabric from different angles and directions, ensuring good pre-shrinking effect when processing fabrics with different texture forms, improving applicability, and being able to evenly store the fabric after the fabric processing is completed, preventing the fabric from being randomly stacked and causing creases after being pressed for a long time, and ensuring the appearance and quality of the finished product.
