Description

Rack track for walking and positioning stretching vehicle in fabric stretching system

Technical Field

The utility model belongs to the technical field of the textile production equipment, a rack rail that is used for tensile car walking and location in the tensile system of fabric is related to.

Background

The fabric stretching system needs to ensure that two sides of the fabric are stretched in parallel in the fabric stretching process, so that the stretching lengths of the two sides of the fabric are the same (the length deviation of the two sides is generally required to be not more than 2mm), the condition that the lengths of the two sides of the fabric are deviated in the stretching process, the product quality and the yield of the fabric are influenced due to deviation damage in the using process is avoided, and great economic loss is caused to a user.

The track for walking and positioning of the stretching vehicle is a stretching track for positioning an anchor pin, the design structure of the track is a track with U-shaped end surfaces, wherein the end surfaces are formed by welding two channel steels with standard length sections back to back, the track surfaces are machined, and the anchor pins for locking and positioning a stretching system are uniformly distributed in the middle of the track at intervals of 500 mm. The existing track has more welding, so the overall deformation of the track is larger, and the machining difficulty is increased in order to ensure the parallelism of the track after the welding is finished; in addition, the whole stretching system needs to be positioned by the anchor pin, and the stretching parallelism of two sides of the fabric is guaranteed, so that the position accuracy of the positioning anchor pin with the interval of 500mm in the middle of the track is required to be accurate, the position accuracy difficulty of the positioning anchor pin in processing the anchor pin positioning hole is high, and the inaccurate position of the positioning anchor pin can directly cause the length deviation of two sides of the fabric, thereby seriously affecting the product quality. In addition, the existing stretching system provided with the anchor pin positioning stretching track adopts a two-stage stretching working principle, namely, a fabric is stretched by a stretching frame, then the stretching frame is locked on the anchor pin in the middle of the stretching track by an anchor hook, and then the fabric is stretched by a second-stage transmission-screw rod on the stretching frame. Due to the length limitation of the wire rod, the stretching track positioned by the anchor pin obviously cannot meet the requirements of fabric stretching with longer length and higher elongation; in order to stretch the fabric with longer length and higher elongation, some fabric production enterprises adopt a method of stretching for multiple times in the production process, so that the labor intensity of workers is increased, and the temperature rise and drop of the fabric stretching for multiple times undoubtedly have serious influence on the product quality because the fabric stretching needs to be heated and has higher temperature requirements, and meanwhile, the production cost of the enterprises is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the problem that prior art exists, thereby provide a design structure exquisiteness, location convenient operation, thereby can guarantee accurately that the tensile depth of parallelism in fabric both sides effectively improves the rack track that the tensile quality of fabric was walked and was fixed a position in the fabric stretching system.

The technical solution adopted to achieve the above-mentioned object of the invention is as follows: the rack rail for walking and positioning the stretching vehicle in the provided fabric stretching system is provided with a long straight bottom beam with a section of standard length, a straight rail surface is installed at the top of the bottom beam, a rack is embedded in the middle of the rail surface along the length direction, the top of the rack is flush with the top of the rail surface, and a plurality of installation bases are arranged at the bottom of the bottom beam.

The utility model discloses further technical solution still includes: the middle part of the rail surface along the length direction is provided with a long straight groove, the rack is embedded in the groove, and the top of the rack is flush with the top of the rail surface.

In practical application, two groups of rack tracks with the same number are respectively and tightly connected into two long straight rack tracks which are equal in length and have the same tooth surface by bolts, the two long straight rack tracks are symmetrically arranged on two sides of a fabric to be stretched, two ends of the fabric to be stretched along the width direction are stretched and respectively connected to a main driving roller and a stretching roller of a fabric stretching system, then walking gears sleeved under two stretching vehicles at two side ends of the stretching rollers are respectively arranged on racks on the two track surfaces in a meshing transmission mode, and the two stretching vehicles on two sides are driven to synchronously move and position on the two rack tracks by an electric control system during working, when the fabric is stretched, the fabric is firmly locked on the track through the braking system of the stretching vehicle, so that different requirements of different fabrics on extension in the stretching process are met, and the parallelism of forces on two stretched sides of the fabric is more accurately ensured.
