Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a rapier loom. Referring to fig. 1, the rapier loom comprises a frame 1 and a workbench 2 fixedly arranged on the frame 1, and a weaving assembly 3 and a winding assembly 4 are sequentially arranged on the frame 1 along the cloth transmission direction. After the warp and the weft are woven into cloth through the warp weaving assembly 3, the cloth is rolled through the rolling assembly 4.

Referring to fig. 1 and 2, the winding assembly 4 includes a cloth pressing roller 41 disposed above the table 2 and extending in the width direction of the table 2, and a winding roller 42 disposed in parallel above the cloth pressing roller 41. The cloth pressing roller 41 comprises a first pressing roller 411 and a second pressing roller 412 which are arranged in parallel and both ends of which are respectively connected to the inner wall of the frame 1. The axial direction of the wind-up roll 42 is the same as the axial direction of the cloth pressing roll 41, and the roll surfaces of the first pressing roll 411 and the second pressing roll 412 of the wind-up roll 42 are abutted against each other under the action of gravity. An actuating mechanism for driving the first pressing roller 411 and the second pressing roller 412 to rotate respectively is connected to the frame 1.

Referring to fig. 1 and 2, the power mechanism drives the first pressing roller 411 and the second pressing roller 412 to rotate, and drives the wind-up roller 42 to rotate under the action of friction force. When the cloth is output outwards, the cloth firstly passes through a gap between the first pressing roller 411 and the workbench 2, then passes through a gap between the first pressing roller 411 and the second pressing roller 412, and finally is wound on the outer annular surface of the winding roller 42. Along with the gradual increase of the thickness of the cloth on the winding roller 42, the winding roller 42 will move away from the workbench 2, and when the winding roller 42 moves to the uppermost end of the side wall of the rack 1, the winding operation is completed.

Referring to fig. 2, for preventing wind-up roll 42 from taking place the skew in the rolling process, be connected with respectively on the frame 1 two relative inner walls with wind-up roll 42 tip inconsistent mounting panel 5, the vertical guide way 51 of setting up towards wind-up roll 42 of seting up on mounting panel 5 to wind-up roll 42 tip sets firmly the guide block of sliding connection in guide way 51. When the wind-up roller 42 winds, the wind-up roller 42 can be prevented from shifting in the horizontal direction only by the guide block sliding in the vertical direction in the guide groove 51.

Referring to fig. 1 and 2, the sizes of the woven cloth by different weaving methods are different, in order to meet the rolling requirements of the cloth with different widths, a guide roller 6 which is arranged in parallel with the second pressing roller 412 and extends along the length direction of the second pressing roller 412 is fixedly arranged on one side of the frame 1, two ends of the guide roller 6 are respectively sleeved with a lantern ring 7 in a sliding manner, and the lantern ring 7 is connected with the side wall of the mounting plate 5 through an L-shaped connecting rod 8. An adjusting screw 71 is screwed on the lantern ring 7, the adjusting screw 71 passes through the lantern ring 7, and the end part of the adjusting screw abuts against the outer annular surface of the guide roller 6.

Then, a new wind-up roll 42 is slidably connected between the two mounting plates 5 to perform the wind-up operation.

Referring to fig. 2, along with the gradual increase of cloth thickness on wind-up roll 42, to wind-up roll 42's pressure crescent, for preventing that lantern ring 7 from taking place to rotate under the pressure effect, the equidistant stopper 61 that has set firmly many edges guide roll 6 length protection line extensions on the outer anchor ring of guide roll 6 to set up the spacing groove 72 with stopper 61 sliding connection on the lantern ring 7 inner ring face.

Referring to fig. 3, a flattening thread 4111 for stretching the cloth is formed on an outer circumferential surface of the first pressing roller 411, and spiral directions of the flattening threads 4111 at both ends of the first pressing roller 411 are opposite. When the first pressing roller 411 rotates, the flattening threads 4111 at both ends exert an expanding force on the cloth, which extends along the length direction of the first pressing roller 411, so that wrinkles on the surface of the cloth are flattened.

Referring to fig. 1 and 3, in order to ensure that the cloth woven by the wefts of different specifications has different thicknesses, the two side walls of the frame 1 are respectively provided with chutes 11 perpendicular to the cloth pressing roller 41 to ensure that the cloth can smoothly pass through the gap between the first pressing roller 411 and the second pressing roller 412. The two ends of the frame 1 located in the sliding groove 11 are respectively connected with a first sliding block 9 and a second sliding block 10 in a sliding manner, the end of the first pressing roller 411 passes through the sliding groove 11 and is connected to the first sliding block 9 in a rotating manner, and the end of the second pressing roller 412 passes through the sliding groove 11 and is connected to the second sliding block 10 in a rotating manner. The power mechanism comprises a first motor 16 fixed on the first slider 9 and coaxially fixed with the first press roller 411, and a second motor 17 fixed on the second slider 10 and coaxially fixed with the second press roller 412.

Referring to fig. 3, the rack 1 is provided with a slide rail 12 at the upper end and the lower end of the chute 11, and the slide rail 12 is slidably sleeved at the two ends of the first pressing roller 411 and the second pressing roller 412. The frame 1 is connected with a driving assembly 13 for the movement of the first slide block 9 and the second slide block 10. The driving assembly 13 includes a first rack 131 fixedly disposed on the lower end surface of the first slider 9, a second rack 132 located above the first rack 131 and fixedly connected to the lower end surface of the second slider 10, and a gear 133 engaged with the first rack 131 and the second rack 132 respectively. A driving motor 134 coaxially fixed with the gear 133 is fixedly arranged on the outer wall of the frame 1.

Referring to fig. 3, the driving motor 134 drives the gear 133 to rotate, and the first sliding block 9 and the second sliding block 10 are driven to move in opposite directions or opposite directions by the meshing action of the first rack 131 and the second rack 132, so that the first pressing roller 411 and the second pressing roller 412 can approach and separate from each other, and cloth with different thicknesses can pass through the pressing roller conveniently.

Referring to fig. 3, in order to ensure the smoothness of the sliding processes of the first slider 9 and the second slider 10, the rack 1 has a strip-shaped groove 14 formed in the positions corresponding to the first rack 131 and the second rack 132, and the first rack 131 and the second rack 132 are rotatably connected with pulleys 15 which are abutted to the strip-shaped groove 14, so that the friction force of the two racks in the sliding processes is reduced.

The implementation principle of the rapier loom in the embodiment of the application is as follows: first, the driving motor 134 drives the gear 133 to rotate, so as to drive the first rack 131 and the second rack 132 to slide, and the distance between the first pressing roller 411 and the second pressing roller 412 is adjusted according to the thickness of the cloth. Then, the adjusting screw 71 is loosened, the collar 7 is slid along the longitudinal direction of the guide roller 6, the distance between the two mounting plates 5 is adjusted in accordance with the width of the cloth, and after the adjustment is completed, the adjusting screw 71 is tightened again. Finally, the weaving assembly 3 weaves the warp and weft into cloth, and the cloth passes through the gap between the first pressing roller 411 and the second pressing roller 412 after being stretched by the flattening screw 4111, and finally is wound on the winding roller 42 to complete the winding operation.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
