[0023] Due to the double guide rail structure of the current spinning machine steel belt type collection and dropping yarn tube transportation, the convex plate lower support seat on the guide rail slides as a whole in the guide rail, and the guide rail is often made of bent steel plates. The bending process is difficult to meet the consistency requirements of the guide rail. The poor consistency of the guide rail will cause difficulties in installation and debugging, which in turn affects the operating state of the convex plate lower support seat, and the guide rail bent from the steel plate is easy to deform during use and transportation, resulting in abnormal noise and jamming when the yarn tube is transported, which is easy to cause damage to parts. In view of this, the inventor of the present application provides a guide rail structure for spinning machine steel belt type collection and dropping yarn tube transportation, which can enhance the strength of the guide rail and extend the service life of the guide rail.

[0024] like Figure 1-7 As shown, the guide rail structure of the steel belt type bobbin conveying of the spinning frame includes four guide rail assemblies 1, which are distributed in a rectangular shape below the spinning frame, and a pulley 8 is arranged between two adjacent groups of guide rail assemblies 1, and each guide rail assembly 1 includes a support seat 2, and guide rails 3 are symmetrically arranged on the support seat 2, and the two symmetrically arranged guide rails 3 are both aluminum alloy profiles, and the two guide rails 3 include a rectangular tube 31 and a square columnar support surface 32, and the square columnar support surface 32 is arranged on the upper side of the rectangular tube 31, and the square columnar support surface 32 is higher than the rectangular tube 31, and a cavity 33 is arranged between the two guide rails 3; a convex disc lower support seat 4 is arranged in the cavity 33, and the upper part of the convex disc lower support seat 4 overlaps the upper surface of the two guide rails 3; the upper part of the convex disc lower support seat 4 is connected to the convex disc upper support seat 6 through a connecting piece 5, and a convex disc 7 is clamped between the convex disc upper support seat 6 and the convex disc lower support seat 4;

[0025] The four guide rail assemblies 1 are connected by an annular toothed belt 9 , and the annular toothed belt 9 is arranged on one side of the lower part of the cam lower bracket 4 , and the annular toothed belt 9 is meshed with the pulley 8 .

[0026] Based on the above embodiment, the surface of the guide rail 3 of the aluminum alloy profile is hard-oxidized to enhance the strength of the guide rail 3; the guide rail 3 has a simple structure and is easy to mass produce. The consistency of the guide rail 3 is easy to ensure through the rectangular tube 31. The guide rail 3 is directly installed on the support seat 2, which is easy to install and debug.

[0027] In this embodiment, if Figure 1 As shown, a plurality of cam lower supports 4 are placed in the cavities 33 of the two rails 3 of each guide rail assembly 1. When the pulley 8 rotates, the annular toothed belt 9 meshing therewith is driven to move, and the rotation of the annular toothed belt 9 causes the cam lower supports 4 to move along the guide rail 3.

[0028] Based on the above embodiment, when the pulley 8 rotates, it drives the annular toothed belt 9 to move along the guide rail 3 in the cavity 33 , and the movement of the annular toothed belt 9 drives the plurality of cam lower brackets 4 connected thereto to move along the guide rail 3 .

[0029] In this embodiment, if Figure 2-4 As shown, the cam lower support seat 4 is T-shaped as a whole, and the cam lower support seat 4 includes a support plate 41, a protrusion 42 and a transmission part 43. The support plate 41 is an isosceles trapezoid, and a wear-resistant sheet 44 is provided on the lower surface of the support plate 41, and the lower surface of the wear-resistant sheet 44 is in contact with the square columnar support surface 32 of the guide rail 3; the protrusion 42 is arranged below the support plate 41, the protrusion 42 is arranged in the cavity 33, and there is a gap between the protrusion 42 and the two guide rails 3; the transmission part 43 is arranged below the protrusion 42, and one side of the transmission part 43 is connected to the annular toothed belt 9, and a plurality of weight-reducing grooves 45 are provided on the protrusion 42 of the cam lower support seat 4.

[0030] Based on the above embodiment, the wear-resistant sheet 44 contacts the upper surface of the guide rail 3. When the cam lower support seat 4 moves along the guide rail 3, only the wear-resistant sheet 44 and the guide rail 3 will generate friction, which reduces the friction force and increases the service life of the cam lower support seat 4. There is a gap between the protrusion 42 and the guide rail 3, which can prevent the guide rail 3 from affecting the operation of the cam lower support seat 4 and ensure smooth transportation of the yarn tube.

[0031] In this embodiment, if Figure 5 As shown, the connecting member 5 is arranged above one side of the shorter side of the support plate 41, and a U-shaped convex disc upper support seat 6 is installed on the upper end of the connecting member 5.

[0032] Based on the above embodiment, the shorter side of the convex disc lower support 4 is located on the inner side of the four rectangular guide rail assemblies 1, so that it can move smoothly at the pulley 8 to avoid damage to the convex disc lower support 4 due to bumps during rotation; the bobbin placement protrusion 64 can be used for temporary storage of bobbins.

[0033] In this embodiment, if Figure 2 , Figure 7 As shown, the bobbin is placed on the convex disc 7, which includes a convex disc base 71, a clamping portion 72 and a convex disc head 73. The convex disc base 71 is placed on the support plate 41 of the convex disc lower bracket 4, and the height of the convex disc base 71 is the same as the height of the connecting member 5; the clamping portion 72 is arranged above the convex disc base 71, and the clamping portion 72 is clamped into the U-shaped convex disc upper bracket 6, and the clamping portion 72 is positioned at three points by the side walls of the placing portion 61 and the abutting portion 63 and the positioning protrusion 65; the convex disc head 73 is arranged above the clamping portion 72, and the convex disc head 73 is located inside the bobbin.

[0034] Based on the above embodiment, the convex disc base 71 of the convex disc 7 is placed on the support plate 41, and the convex disc base 71 is limited by the convex disc upper bracket 6. The placement portion 61 of the convex disc upper bracket 6 and the side wall of the abutment portion 63 and the positioning protrusion 65 position the clamping portion 72 of the convex disc 7. Since the length of the abutment portion 63 is shorter than the length of the placement portion 61, and the length of the abutment portion 63 is 2 / 3 to 3 / 4 of the height of the support plate 41, it is more convenient to disassemble and assemble the convex disc 7.

When the pulley 8 rotates, the annular toothed belt 9 is moved by the cooperation between the transmission grooves 81 and the transmission tooth block 92.

[0036] Based on the above embodiments, Figure 3 As shown, since the annular toothed belt 9 is meshed with the pulley 8, when the pulley 8 rotates, the annular toothed belt 9 is driven to move, and the transmission groove 81 and the transmission tooth block 92 cooperate to realize the transmission and positioning of the pulley 8 and the annular toothed belt 9.

[0037] The working principle of the utility model is as follows: first, the rotation direction of the four pulleys 8 is set, and the rotation direction of the pulleys 8 determines the moving direction of the annular toothed belt 9 meshing therewith. When the four pulleys 8 start to rotate at the same time, the annular toothed belt 9 is driven to start moving in the cavity 33 of the guide rail assembly 1. While the annular toothed belt 9 moves, it drives several cam lower brackets 4 connected thereto to move regularly along the guide rail 3 at the same time; at this time, the cam lower bracket 4 drives the cam upper bracket 6 to move through the connecting piece 5, and the cam 7 on the support plate 41 moves with the cam lower bracket 4, and the cam 7 is positioned by the cam upper bracket 6, and the connecting piece 5, the cam upper bracket 6, the cam 7 and the yarn tube on the cam 7 will move along the guide rail 3 together with the cam lower bracket 4.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
