DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Embodiment 1

[0029] Reference Figure 1-Figure 6 As shown, the utility model is a rubber stripping device, which is used for stripping the rubber coating on the surface of a steel pipe, comprising:

[0030] The driving assembly 1 comprises a driving wheel 11, an idler wheel 12, a pressure wheel 13 and a driving source 14. A plurality of driving wheels 11 and an idler wheel 12 are alternately arranged along the same straight line. A plurality of pressure wheels 13 are arranged at intervals parallel to the arrangement direction of the driving wheels 11 and the idler wheels 12. A channel for the steel pipe to pass through is formed between the pressure wheel 13 and the driving wheels 11 and the idler wheels 12. The driving source 14 is used to drive the driving wheel 11 to rotate.

[0031] The cutting tools 2 are provided in two groups in a floating manner perpendicular to the extending direction of the channel, and the two groups of cutting tools 2 are respectively located on both sides of the channel.

[0032] Specifically, multiple driving wheels 11 and idler wheels 12 are alternately arranged in the horizontal direction, and multiple pressure wheels 13 are arranged at intervals in the horizontal direction, and the pressure wheel 13 is located above the driving wheel 11 and the idler wheel 12, and a linear channel is formed between the pressure wheel 13 and the driving wheel 11 and the idler wheel 12. When the driving wheel 11 rotates, it cooperates with the idler wheel 12 and the pressure wheel 13 to drive the steel pipe to move forward along the channel; two groups of cutting tools 2 are respectively floatingly arranged on the upper and lower sides of the channel.

[0033] Working principle: The driving source 14 drives the driving wheel 11 to rotate, and the rotating driving wheel 11 drives the steel pipe to move forward along the channel formed between the driving wheel 11, the idler wheel 12 and the pressure wheel 13. When the linearly moving steel pipe passes through the positions of the two cutters 2 located on its upper and lower sides, the rubber coating on the surface of the steel pipe will be cut by the cutters 2, thereby realizing the automatic peeling of the rubber coating.

[0034] It can be imagined that the pressure wheel 13, the driving wheel 11 and the idler wheel 12 not only play the role of driving the steel pipe to move in a straight line, but also have a certain straightening effect on the steel pipe, which can ensure that the steel pipe passes through the tool 2 with a good straightness, which is beneficial for the tool 2 to peel off the rubber coating; at the same time, it can be imagined that the floating setting of the tool 2 can further ensure that the tool 2 will not scratch the surface of the steel pipe during the peeling process (specifically, during the movement of the steel pipe, when the straightness of the steel pipe jumps, the tip of the tool 2 contacts the surface of the steel pipe, and the tool 2 is forced to float in the direction away from the steel pipe, thereby preventing the tool 2 from scratching the surface of the steel pipe).

[0035] Reference Figure 4As shown, further, it includes a base 3, the base 3 includes a base 31 and a frame 32, the base 31 is horizontally arranged, the frame 32 includes two vertical plates arranged at intervals on the base, each driving wheel 11 and the idler wheel 12 are rotatably connected between the two vertical plates through a rotating shaft 15, and a horizontal plate is vertically connected between the two vertical plates, and the pressure wheels 13 are all floatingly connected to the horizontal plate through the floating seat 4 perpendicular to the extension direction of the channel. Specifically, the floating pressure wheel 13 can float to a certain extent when the straightness of the steel pipe changes, avoiding damage to the steel pipe or the pressure wheel 13 caused by hard contact between the pressure wheel 13 and the steel pipe; and the floating pressure wheel 13 makes the device applicable to steel pipes of different diameters, which makes the device have high versatility.

[0036] Reference Figure 2 and Figure 3 As shown, further, two fixing rings 16 are coaxially arranged on the rotating shaft 15 connected to the driving wheel 11, respectively located on both sides of the driving wheel 11, and the position of the fixing ring 16 on the rotating shaft 15 is adjustable. Specifically, the fixing ring 16 is coaxially sleeved on the rotating shaft 15, and a plurality of first screw holes are opened on the circumferential surface of the rotating shaft 15, and second screw holes matching the first screw holes are vertically opened on the circumferential surface of the fixing ring 16, and the fixing ring 16 can be fixed to the rotating shaft 15 by screws; the two fixing rings 16 can limit the steel pipe on both sides to prevent the steel pipe from deviating during movement, and the distance between the two fixing rings 16 can be adjusted, which can be suitable for steel pipes of different diameters.

[0037] Reference Figure 2 , Figure 3 and Figure 5 As shown, further, the two cutters 2 are respectively connected to the base and the horizontal plate in a floating manner through the floating seat 4, and the two cutters 2 are staggered in the extension direction of the channel. The two cutters 2 cut the rubber coating on the surface of the steel pipe at the upper and lower sides of the steel pipe to achieve the stripping of the rubber coating.

[0038] Furthermore, the base or the horizontal plate is respectively connected with a plurality of connecting bolts 5 perpendicular to the extension direction of the channel, the floating seat 4 is connected thereto by sliding along the length direction of the connecting bolts 5, and the connecting bolts 5 are sleeved with a spring 6 located between the nut thereof and the floating seat 4. Specifically, the floating seat 4 can slide along the connecting bolts 5, and when the pressure wheel 13 or the cutter 2 connected to the floating seat 4 is forced to move in a direction away from the steel pipe due to the change in the straightness of the steel pipe, the floating seat 4 will move along the connecting bolts 5 toward the nut of the connecting bolt 5, compressing the spring 6 located between the floating seat 4 and the nut of the connecting bolt 5, and when the above-mentioned force disappears, the floating seat 4 will drive the cutter 2 or the pressure wheel 13 to reset under the elastic force of the compressed spring 6, thereby realizing the floating effect.

[0039] Furthermore, two driving wheels 11 and two idler wheels 12 are provided, the idler wheel 12 located between the two driving wheels 11 corresponds to the position of the cutter 2 connected to the horizontal plate, and three pressure wheels 13 are provided and correspond to the positions of the two driving wheels 11 and the other idler wheel 12. The above provides a setting method of the driving wheel, the idler wheel and the pressure wheel, but is not limited to the above setting method.

[0040] Reference Figure 6 As shown, further, the cutter 2 includes a fixed block 21 and a blade 22. A knife groove 23 extending along the length direction of the fixed block 21 is provided at one end thereof, and the blade 22 is arranged in the knife groove 23. A top screw hole vertically penetrating the knife groove 23 is provided on the side of the fixed block 21. A butterfly screw 24 is screwed into the top screw hole, and the butterfly screw 24 abuts against the blade 22. The butterfly screw 24 has a function similar to that of a top screw, fixing the blade 22 in the knife groove 23; when the blade 22 needs to be replaced, the blade 22 can be replaced by simply loosening the butterfly screw 24, which is convenient and practical.

[0041] Furthermore, it also includes a controller, which is connected to the driving source 14 and is connected to a control button 7, and a staff can operate and control the device through the control button 7.

[0042] Furthermore, the driving wheel 11 and the pressing wheel 13 are both gears. It is conceivable that the gears can generate greater friction with the rubber coating on the surface of the steel pipe when rotating, which is conducive to driving the steel pipe to move forward.

[0043] Embodiment 2

[0044] The utility model also discloses a production line, comprising the glue stripping device as in the first embodiment.

[0045] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
