Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe processing, in particular to an anti-loosening clamping mechanism for PE pipe cutting. Background Art

[0002] PE (polyethylene) material is widely used in the field of water pipe manufacturing due to its high strength, corrosion resistance, and non-toxicity. Because it will not rust, it is an ideal pipe to replace ordinary iron water pipes. During production, PE pipes are directly extruded through an extruder. After shaping, the PE pipes need to be cut to the appropriate length to facilitate processing and collection of the PE pipes.

[0003] When cutting existing PE pipes, a triangular claw plate is usually used to fix one end of the pipe, but the fixing effect is poor, which can easily cause the PE pipe to shake when cutting, and it is not convenient to adjust according to the cutting position of the pipe.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-loosening clamping mechanism for PE pipe cutting is proposed, in order to achieve a more practical purpose. Utility Model Content

[0005] The utility model aims to provide a PE pipe cutting anti-loosening clamping mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PE pipe cutting anti-loosening clamping mechanism, comprising a pad substrate, an air pressure adsorption component and a clamping component, the inner side of the pad substrate is provided with an arc-shaped pad surface, and one side of the upper end of the pad substrate is provided with a clamping component, the clamping component comprises a reinforcing plate, a rotating rod, a plastic sleeve, an external drive motor and a limit seat, the two sides of the reinforcing plate are sleeved with plastic sleeves, and the plastic sleeve is provided with a rotating rod near the end of the pad substrate, the outer wall of the rotating rod is installed with an external drive motor, a limit seat is provided on the outer side of one end of the plastic sleeve, and air pressure adsorption components are embedded on both sides of the inner wall of the arc-shaped pad surface, the air pressure adsorption component comprises a support plate, a telescopic gas rod, a plastic pad and a strip groove, the inner side of the support plate is obliquely provided with a telescopic gas rod, and the outer wall of the support plate is attached to the plastic pad, and strip grooves are arranged on the surface of the plastic pad.

[0007] Furthermore, a PE pipe body is placed inside the arc-shaped pad surface.

[0008] Furthermore, a mounting groove is provided on one side of the bottom of the pad substrate.

[0009] Furthermore, the support plate forms an air pressure lifting structure between the telescopic gas rod and the pad base material, and the grooves of the support plate and the pad base material are embedded in each other.

[0010] Furthermore, the strip-shaped grooves are evenly distributed along the central axis of the plastic pad.

[0011] Furthermore, the reinforcement plate and the plastic sleeve plate are wrapped and connected, and the plastic sleeve plate is symmetrically arranged on the outer side of the reinforcement plate.

[0012] Furthermore, the plastic sleeve and the rotating rod form a rotating structure through an external driving motor, and the limiting seat and the plastic sleeve are arranged in a semi-wrapped manner.

[0013] The utility model provides a PE pipe cutting anti-loosening clamping mechanism, which has the following beneficial effects:

[0014] 1. The utility model is based on the common wrapping type fixation, adopts the pad substrate as the bottom support, and adopts the rotating pressing plate on the top to clamp and fix the PE pipe body;

[0015] The slightly lower pad base material at one end and the rotatable and outwardly extending reinforcement plate make it easy to take the PE pipe body from the curved pad surface of the pad base material. The installation slide groove at the bottom of the pad base material adjusts the position of the entire mechanism to meet the positioning requirements.

[0016] 2. In the utility model, the air pressure adsorption components are symmetrically arranged in the arc-shaped pad surface. Initially, they are in an embedded setting. The local convex setting can make the plastic pad on the surface deform when it is fixed to the PE pipe. The air in the strip groove is squeezed out to increase the adsorption force, so that the plastic pad is in close contact with the PE pipe relatively closely.

[0017] The telescopic gas rod at the bottom of the plastic pad can move the plastic pad inward and away from the PE pipe, making it easier to remove; the telescopic gas rod can also be extended to pressurize the PE pipe to make the clamping more stable. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3The utility model provides a technical solution: a PE pipe cutting anti-loosening clamping mechanism, comprising a pad substrate 1, a pneumatic adsorption component 3 and a clamping component 5, the inner side of the pad substrate 1 is provided with an arc-shaped pad surface 2, and the upper end side of the pad substrate 1 is provided with a clamping component 5, the clamping component 5 comprises a reinforcing plate 501, a rotating rod 502, a plastic sleeve 503, an external drive motor 504 and a limit seat 505, both sides of the reinforcing plate 501 are sleeved with plastic sleeves 503, and the plastic sleeve 503 is provided with a rotating rod 502 near the end of the pad substrate 1, the outer wall of the rotating rod 502 is installed with an external drive motor 504, and a limit seat 505 is provided on the outer side of one end of the plastic sleeve 503, and the inner wall of the arc-shaped pad surface 2 is embedded with pneumatic adsorption components 3, and the pneumatic adsorption component 3 comprises a support plate 301, a telescopic gas rod 302, a plastic pad 303 and a strip groove 30 4. A telescopic gas rod 302 is obliquely arranged on the inner side of the support plate 301, and a plastic pad 303 is attached to the outer wall of the support plate 301, and strip grooves 304 are arranged on the surface of the plastic pad 303; a PE pipe body 4 is placed on the inner side of the arc-shaped pad surface 2; a mounting slide groove 6 is arranged on one side of the bottom of the pad substrate 1; the support plate 301 forms an air pressure lifting structure between the telescopic gas rod 302 and the pad substrate 1, and the grooves of the support plate 301 and the pad substrate 1 are interlocked; the strip grooves 304 are evenly arranged along the central axis of the plastic pad 303; a wrapping connection is formed between the reinforcement plate 501 and the plastic sleeve plate 503, and the plastic sleeve plate 503 is symmetrically arranged on the outer side of the reinforcement plate 501; the plastic sleeve plate 503 and the rotating rod 502 form a rotating structure through an external driving motor 504, and the limit seat 505 and the plastic sleeve plate 503 are semi-wrapped.

[0025] Based on the common wrapping type fixation, the pad substrate 1 is used as the bottom support, and the top is used with a rotating pressing plate to clamp and fix the PE pipe body 4;

[0026] The slightly lower pad substrate 1 at one end and the rotatable and outwardly extending reinforcement plate 501 facilitate the removal and placement of the PE pipe body 4 from the arc-shaped pad surface 2 of the pad substrate 1. The installation slide groove 6 opened at the bottom of the pad substrate 1 adjusts the position of the entire mechanism to meet the positioning requirements;

[0027] The air pressure adsorption component 3 symmetrically arranged in the arc-shaped pad surface 2 is initially in an embedded setting, and the partially raised setting can cause the plastic pad 303 on the surface to deform when the PE pipe is fixed, and the air in the strip groove 304 is squeezed out to increase the adsorption force, so that the plastic pad 303 is in close contact with the PE pipe relatively closely;

[0028] The telescopic gas rod 302 at the bottom of the plastic pad 303 can move the plastic pad 303 inward and away from the PE pipe, making it easier to get rid of the plastic pad. The telescopic gas rod 302 can also be extended to pressurize the PE pipe, making the clamping more stable.

[0029] The limit seat 505 on the pad substrate 1 is arranged on the outer side of the rotating end of the plastic sleeve 503. The limit seat 505 is open at one end facing the arc pad surface 2. Therefore, the rotating end of the plastic sleeve 503 can rotate on the inner side of the limit seat 505, and the rotation radius of the plastic sleeve 503 is limited by the limit seat 505, thereby controlling the expansion range of the plastic sleeve 503, avoiding mechanical fatigue and affecting the pressurization accuracy.

[0030] Working principle: For this type of PE pipe cutting anti-loosening clamping mechanism, first, the PE pipe body 4 to be cut is placed on the inner side of the arc-shaped pad surface 2 of the pad substrate 1, and then the external drive motor 504 on the rear side is controlled to drive the rotating rod 502 to rotate, so that the reinforcing plate 501 is gradually rotated and pressed on the upper position of the PE pipe body 4. With continuous squeezing, the plastic sleeve 503 is in close contact with the PE pipe body 4. When pressurized, the PE pipe body 4 will squeeze the plastic pad 303 at the bottom, causing the plastic pad 303 on the surface to deform, and the air in the strip groove 304 is squeezed out to increase the adsorption force, so as to realize a structure similar to a suction cup, so as to adsorb and fix the top PE pipe body 4. In addition, the telescopic gas rod 302 can be controlled to extend to squeeze the plastic pad 303 close to the PE pipe body 4, so as to ensure the all-round fixation of the PE pipe body 4.

[0031] When the cutting is completed, the telescopic gas rod 302 is retracted to drive the plastic pad 303 to retract, so that the plastic pad 303 is separated from the PE pipe body 4, and then the external driving motor 504 controls the plastic sleeve 503 to restore the original state.

[0032] The above description is only a specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be thought of by any technician familiar with the field within the technical scope disclosed by the utility model without creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
