Description

Technical Field

[0001] This utility model relates to the field of PU tube production technology, and in particular to a rapid cutting device for PU tube production. Background Technology

[0002] PU tubing is a widely used industrial hose, short for polyurethane tubing. Its superior physical and mechanical properties and good chemical stability have led to its replacement of traditional rubber hoses, PVC hoses, and other materials in numerous fields.

[0003] Currently, PU tubing requires slitting during production. A search reveals a patent with application number 202221689057.3, which discloses a slitting device for PU tubing production. This device includes a base plate placed on a frame, with a blade holder slidably mounted on the base plate. Blades are slidably mounted on the blade holder, and a support is also provided on the blade holder, with a cylinder mounted on the support. This prior art, by sliding the blade holder, allows the PU tubing to pass through different circular holes, thus enabling the device to cut PU tubing of different diameters and simultaneously cut multiple PU tubings. However, this prior art lacks a PU tubing conveying structure, preventing automated forward conveying during the slitting process and hindering the rapid completion of slitting of entire PU tubing sections, severely impacting slitting efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1, referring to Figure 1 and Figure 4 A rapid slitting device for PU pipe production includes a reciprocating slitting mechanism, a housing 1, a processing table 2 welded to the top outer wall of the housing 1, and a vertical plate 3 welded to the top outer wall of the processing table 2. An inclined guide plate 23 is fixedly connected to the side of the processing table 2 near the pipe cutting knife 7, and a control panel 24 is fixedly installed on the other outer wall of the housing 1.

[0027] Specifically, the reciprocating slitting mechanism includes a first stepper motor 4 fixedly installed on the upper outer wall of one side of the vertical plate 3, a rotating wheel 5 fixedly mounted on the output shaft of the first stepper motor 4, a knife holder 6, a pipe cutter 7 fixedly installed on the bottom outer wall of the knife holder 6, and a rocker arm 8 movably installed between the rotating wheel 5 and the knife holder 6. The output shaft of the first stepper motor 4 passes through the upper part of the vertical plate 3.

[0028] Furthermore, two guide grooves 9 are symmetrically opened on the other side of the vertical plate 3, and two guide members 10 are welded to the side wall of the tool holder 6. The outer walls of the two guide members 10 are slidably connected to the inner walls of the two guide grooves 9 respectively. Through the guiding cooperation between the two guide members 10 and the two guide grooves 9, the stability of the reciprocating motion of the tool holder 6 in the vertical direction can be guaranteed.

[0029] Example 2, refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 This embodiment is an optimization based on embodiment 1. Specifically, the feeding mechanism includes a second stepper motor 11 fixedly installed on the outer wall of the rear side of the housing 1, a PU tube release disc 12 fixedly mounted on the output shaft of the second stepper motor 11, two mounting brackets 13, two motors 14 fixedly installed on the top outer wall of the two mounting brackets 13 in sequence, and tube feeding wheels 15 fixedly mounted on the output shafts of the two motors 14 in sequence. The output shaft of the second stepper motor 11 passes through the rear side of the housing 1, and the output shafts of the two motors 14 rotate in opposite directions.

[0030] Furthermore, the feeding mechanism also includes a spacing adjustment assembly, which includes two bearing seats 17 symmetrically fixed to the lower outer wall of one side of the vertical plate 3, a bidirectional screw 18 rotatably mounted on the two bearing seats 17, two adjusting blocks 19 symmetrically screwed to the two opposite thread ends of the bidirectional screw 18, and a servo motor 20 fixedly connected to the lower outer wall of the rear side of the vertical plate 3 through a motor seat.

[0031] Furthermore, a row of equally spaced guide wheels 16 are installed at the bottom of both mounting brackets 13. The output shaft of the servo motor 20 is coaxially and fixedly connected to one end of the bidirectional screw 18 via a coupling. A guide rail 21 is fixedly connected to the lower outer wall of one side of the vertical plate 3. Both adjusting blocks 19 are slidably connected to the guide rail 21. The two mounting brackets 13 are respectively fixed to the bottom outer wall of the two adjusting blocks 19. The PU tube release disc 12 is located inside the chassis 1. A channel 22 is opened on one side of the chassis 1, and an outlet is opened in the bottom area of ​​the vertical plate 3.

[0032] The working principle of this utility model is as follows: First, the PU tube release disc 12 with the PU tube wound around it is installed on the output shaft of the second stepper motor 11, and the end of the PU tube is pulled out from the channel 22 and passed through the guide wheel 16 between the two mounting brackets 13.

[0033] Secondly, the bidirectional screw 18 is controlled to rotate forward or backward by the servo motor 20. Then, under the guidance of the guide rail 21, the two adjusting blocks 19 that are threadedly connected to the bidirectional screw 18 will drive the two mounting brackets 13 to move closer or further apart, thereby enabling flexible adjustment of the working distance between the two tube feeding wheels 15, so as to better adapt to the automated conveying of PU tubes of different thicknesses.

[0034] Finally, the second stepper motor 11 controls the rotation of the PU tube release disc 12, and the two motors 14 control the relative rotation of the two tube feeding wheels 15. This allows the PU tubes to be processed to be automatically conveyed forward. The first stepper motor 4 controls the rotation of the rotating wheel 5. Under the linkage effect of the rocker arm 8, the tube cutter 7 will automatically move up and down as the rotating wheel 5 rotates. This facilitates the rapid completion of the entire PU tube slitting process and effectively improves the slitting efficiency. The slitting PU tubes will be discharged in an orderly manner from the guide plate 23. The speed of the first stepper motor 4 can be flexibly adjusted through the control panel 24, which in turn allows for flexible adjustment of the reciprocating cutting frequency of the tube cutter 7, thereby enabling the control of the slitting length of the PU tubes according to requirements.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
