As shown in fig. 1, the embodiment provides a quick peeling machine for a spiral finned tube, which comprises a frame 1, a pushing device 2, a peeling device 3, a receiving cylinder 4 and a supporting device 5.

The frame 1 serves to support other devices, and its shape and structure may be set according to circumstances, and is not limited to the illustrated structure and shape.

The pushing device 2 is mounted on the frame 1. The pushing device 2 includes a hydraulic cylinder 201 and a push rod 202. The hydraulic cylinder 201 is also called as a cylinder, and an oil tank for driving the hydraulic cylinder 201 is also installed on the frame 1. The hydraulic cylinder 201 is fixedly arranged at the left part of the frame 1. The piston rod of the hydraulic cylinder 201 is disposed horizontally and oriented rightward. The push rod 202 is a cylinder, and the push rod 202 is connected with a piston rod of the hydraulic cylinder 201. The push rod 202 is also horizontally disposed, and the longitudinal direction thereof is the left-right direction.

The head stripping device 3 is arranged on the frame 1. Referring to fig. 2, the head peeling device 3 includes two symmetrically arranged sliding members 301 and arc-shaped knife grooves 302 arranged on the sliding members 301. The two sliding members 301 are slidably disposed in opposite directions. In the present embodiment, the distribution direction of the two sliding members 301 is the front-back direction, and the sliding direction of the sliding members 301 is the front-back direction. The opposite sides of the two sliders 301 are each provided with an arc-shaped knife slot 302.

The two arcuate sipes 302 form a circular notch 10 therebetween when the two sliders 301 are brought close to each other. The end position of the push rod 202 corresponds to the position of the circular notch 10, i.e., the axis of the push rod 202 passes through the center of the circular notch 10. The push rod 202 is moved in the left-right direction to approach or separate from the arc-shaped cutter groove 302 by the driving of the hydraulic cylinder 201. A driving cylinder 7 for driving the sliding piece 301 to slide is installed on the frame 1. The two driving cylinders 7 are symmetrically arranged in the front-rear direction. The piston rod of the drive cylinder 7 is connected to the slider 301.

An upper slideway 8 and a lower slideway 9 are arranged on the frame 1, the top of the sliding piece 301 is arranged in the upper slideway 8, and the bottom of the sliding piece 301 is arranged in the lower slideway 9. The upper slideway 8 and the lower slideway 9 play a role of guiding the sliding piece 301, and simultaneously can prevent the sliding piece 301 from being separated from the rack 1 and falling, thereby improving the stability of the quick end-peeling machine of the spiral finned tube.

The material collecting barrel 4 is arranged on the frame 1. The push rod 202 is located on the left side of the slide member 301, and the material receiving cylinder 4 is located at a position below the right side of the slide member 301. The purpose of the take-up barrel 4 is to collect waste material stripped from the spiral finned tube.

The support means 5 functions to feed and support the turn-fin tube. The supporting device 5 includes a bracket 501 and a rotating roller 502 provided on the bracket 501. The bracket 501 is used to support the rotating roller 502. The rotating roller 502 is located above the right side of the receiving barrel 4. The rotating roller 502 is rotatably provided with its axis as a rotating shaft, and the axis of the rotating roller 502 is parallel to the sliding direction of the slider 301, that is, the axis direction of the rotating roller 502 is the front-rear direction. The number of the rotating rollers 502 is plural groups, and the distribution direction is the left-right direction. When the turn-fin tube is placed on the turning roller 502, the height thereof corresponds to the height of the circular notch 10. The rotatably disposed turning rollers 502 may serve to reduce friction when the turn-fin tube is pushed by the push rod 202.

Referring to fig. 3, the rapid peeling machine for the spiral finned tube further comprises two deviation rectifying devices 6 symmetrically arranged in the front-rear direction. The two deviation rectifying devices 6 are matched to rectify the deviation of the push rod 202. The deviation correcting device 6 comprises a deviation correcting cylinder 601 and a deviation correcting plate 602 guide rod 603. The deviation rectifying cylinder 601 is installed on the frame 1, the piston rod of the deviation rectifying cylinder 601 is horizontally arranged, the axial direction of the piston rod is front and back, and the piston rods of the deviation rectifying cylinders 601 of the two deviation rectifying devices 6 are oppositely arranged. One side of the deviation rectifying plate 602 is connected with the deviation rectifying cylinder 601. The other side of the deviation correction plate 602 is provided with a groove for receiving the push rod 202, and the groove is semicircular. The push rod 202 is located between two deviation plates 602. The two deviation-correcting plates 602 clamp the push rod 202 to realize deviation-correcting positioning, and ensure that the push rod 202 moves in a straight direction. In addition, as the push rod 202 can generate friction with the deviation correcting plate 602 during sliding, lubricating oil can be applied between the push rod 202 and the deviation correcting plate 602.

The guide rod 603 is slidably mounted on the frame 1 and the sliding direction is the axial direction thereof, i.e. the guide rod 603 is perpendicular to the push rod 202. The axial direction of the guide rod 603 is the front-rear direction. The end of the guide rod 603 is connected to the correction plate 602. The guide rods 603 serve to guide and support the correction plate 602.

As a further preferred embodiment of the above solution, with reference to fig. 4, the push rod 202 includes a first rod 202a and a second rod 202b. The left end of the first rod 202a is connected with the piston rod of the hydraulic cylinder 201, the right end of the first rod 202a is connected with the left end of the second rod 202b, and the diameter of the second rod 202b is smaller than that of the first rod 202a. And the axis of the first rod 202a coincides with the axis of the second rod 202b. Thus, a step portion is formed between the first rod 202a and the second rod 202b. In addition, the diameter of the second rod 202b is smaller than that of the circular notch 10. The second rod 202b is provided with a smaller diameter to facilitate passing through the circular notch 10, preventing hitting the arc-shaped cutter groove 302. The first rod 202a with a larger diameter ensures the strength and stability of the push rod 202.

The working process of the quick head peeling machine for the spiral finned tubes comprises the following steps:

the turn-fin tube is placed on the support 5 with its area requiring peeling between the two slides 301. The driving cylinder 7 drives the two sliders 301 to move, so that the two arc-shaped cutter grooves 302 clamp the spiral finned tube, wherein the arc-shaped cutter grooves 302 penetrate through the fins of the spiral finned tube. Then the hydraulic cylinder 201 drives the push rod 202 to move rightwards, the push rod 202 pushes the spiral finned tube, and the part of the spiral finned tube needing to be stripped falls into the material receiving barrel 4, so that head stripping is completed.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
