Description

Technical Field

[0001] This utility model relates to the technical field of material drawing, and in particular to a crawler-type drawing machine that can draw and retract materials in a coil. Background Technology

The tensioning system for adjusting the tension was unstable, and the adjustment of the material thickness and diameter was not good enough. The overall cost was high. The use of chains and sprockets resulted in large vibration amplitudes, less material winding on the front and rear trays, and low production efficiency. Utility Model Content

[0026] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1 to 5 As shown in this embodiment, a tracked drawing machine with a disc-type pull and retract mechanism includes a feeding disc 1, a receiving disc 2, a front guide mechanism 3, a pre-straightening mechanism 4, a tracked drawing mechanism 5, and a rear guide mechanism 6. Both the feeding disc 1 and the receiving disc 2 include a rotating disc 7 and a disc motor 8, with the disc motor 8 driving the rotation of the rotating disc 7. The front guide mechanism 3 includes a first transverse guide wheel 9, a first longitudinal guide wheel 10, a second transverse guide wheel 11, a second longitudinal guide wheel 12, a third transverse guide wheel 13, and a third longitudinal guide wheel 14. The pre-straightening mechanism 4 includes a pre-straightening guide wheel 15, which is distributed on both sides. The tracked drawing mechanism 5 includes track wheels 16 and a rubber track 17, with the rubber track 17 driving between the track wheels 16. The rear guide mechanism 6 includes a fourth transverse guide wheel 18 and a fourth longitudinal guide wheel 19.

[0028] Material is wound on the feeding tray 1 and output from the feeding tray 1. It is guided by the first transverse guide wheel 9 and the first longitudinal guide wheel 10 on the front guide mechanism 3 and then guided by the second transverse guide wheel 11, the second longitudinal guide wheel 12, the third transverse guide wheel 13 and the third longitudinal guide wheel 14. After being straightened by the pre-straightening guide wheel 15 to ensure straightness, it passes through the outer mold base 27 and enters the track pulling mechanism 5. Under the rotation of the track wheel 16, the rubber track 17 moves backward. Under the guidance of the fourth transverse guide wheel 18 and the fourth longitudinal guide wheel 19, it enters the receiving tray 2 for winding and storage. It can be processed continuously, which effectively improves the pulling efficiency.

[0029] Both the feeding tray 1 and the receiving tray 2 are equipped with a tray base 20. The tray motor 8 is fixed on the tray base 20. The rotating tray 7 rotates horizontally on the tray base 20. A sensing plate 21 is installed on the drive shaft of the tray motor 8. A plate sensor 22 is fixed on the tray base 20. The plate sensor 22 is connected to the sensing plate 21 for signal transmission. The tray motor 8 drives the rotating tray 7 to feed and receive materials. During the rotation, the amount of material output or input is known by the sensing plate 21 and the plate sensor 22.

[0030] The front guide mechanism 3 includes a front guide bracket 23 and a front guide auxiliary frame 24. A front guide connecting rod 25 connects the front guide bracket 23 and the front guide auxiliary frame 24. The first transverse guide wheel 9 and the first longitudinal guide wheel 10 are located inside the front guide auxiliary frame 24. The second transverse guide wheel 11, the second longitudinal guide wheel 12, the third transverse guide wheel 13, and the third longitudinal guide wheel 14 are located inside the front guide bracket 23. The rear guide mechanism 6 includes a rear guide bracket 31. The fourth transverse guide wheel 18 and the fourth longitudinal guide wheel 19 are located inside the rear guide bracket 31. In terms of material guidance, the transverse guide wheel cooperates with the longitudinal guide wheel to allow the material to pass through the middle hole, maintaining a straight guiding state.

[0031] The pre-straightening mechanism 4 includes a pre-straightening support 26, a pre-straightening guide wheel 15 located at the front end of the pre-straightening support 26, and an outer mold base 27 installed at the rear end of the pre-straightening support 26. Under the action of several pre-straightening guide wheels 15 on the left and right, the material can enter the outer mold base 27 in a straight line and be drawn through the free core. The pre-straightening guide wheels 15 are not powered and rotate by the passage of the material to increase straightness.

[0032] The tracked drawing mechanism 5 includes a drawing frame 28, with track wheels 16 rotatably connected to both ends of the drawing frame 28. A tension adjustment module 29 is installed inside the drawing frame 28. The tension adjustment module 29 moves vertically and abuts against the rubber track 17. The up-and-down movement of the tension adjustment module 29 on the drawing frame 28 allows for a suitable spacing between the upper and lower tension adjustment modules 29 to clamp the material. This provides a wide adjustment range and effectively controls the thickness and diameter of the material. When the track wheels 16 rotate, the rubber track 17 drives the material backward through friction, replacing the original iron mold, improving clamping force and traction. Furthermore, it eliminates the need for chain and sprocket conveying, reducing vibration. The entire drawing frame 28 has a large bearing capacity and low cost. Under the action of the rubber, the material will not deform.

[0033] In addition, a protective cover 30 is hinged to the drawing frame 28, and the protective cover 30 covers the outside of the rubber track 17.

[0034] It should be stated that the above specific embodiments are merely preferred embodiments of this utility model and the technical principles used therein. Within the scope of the technology disclosed in this utility model, any changes or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
