Description

Technical Field

[0001] The utility model relates to the technical field of PE core-rolling pipe production, in particular to a pipe opening grinding device for PE core-rolling pipe production. Background Art

[0002] PE core tube usually refers to a core tube made of polyethylene (PE), which is used to roll various winding materials or winding pipes. Core tubes are usually lightweight, durable, and corrosion-resistant, and are suitable for a variety of industrial and commercial applications. In order to improve the appearance quality, PE core tubes are usually polished during production and processing.

[0003] The Chinese patent "A PE pipe end face grinding device" authorization announcement number "CN213289724U" places the PE pipe to be processed in the fixed splint in the fixing mechanism. The fixed splint is provided with an arc-shaped groove, which fits the surface of the PE pipe, so that it is more convenient and firmer to fix the PE pipe; then, the movable splint is pushed downward by the telescopic performance of the telescopic cylinder itself, and the movable splint style structure is equivalent to the fixed splint, and then the PE pipe can be firmly fixed on the device through the fixing effect of the two splints. The setting of this fixing mechanism can ensure that when the PE pipe is processed, the pipe is more stable and will not be offset, so that the stability and safety are higher during processing.

[0004] In the above scheme, the fixed clamping plate and the movable clamping plate are used to open the arc groove matching the PE pipe to achieve the fixed clamping of the PE pipe. However, the sizes of PE pipes are different during production and processing. Only the fixed arc groove can fix the PE pipe of a single size, which has low practicality.

[0005] Therefore, a pipe opening grinding device for producing PE coiled core pipe is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0027] When implementing: Figure 1-5 As shown, a pipe mouth grinding device for PE coiled core pipe production includes: a base 1, a mounting plate 2 is fixedly connected to one side of the top of the base 1, a motor 3 is fixedly connected to one side of the mounting plate 2, an output shaft of the motor 3 passes through the mounting plate 2 and is fixedly connected to a grinding disc 4, a fixing frame 5 is fixedly connected to the top of the base 1, an electric push rod 6 is fixedly connected to the top of the fixing frame 5, and a fixing mechanism 7 is arranged at the bottom end of the electric push rod 6; wherein, the fixing mechanism 7 includes a supporting plate 701 fixedly connected to the top of the base 1, the bottom end of the electric push rod 6 passes through the fixing frame 5 and is fixedly connected to an air cylinder 702, the inner wall of the air cylinder 702 is slidably connected to a first piston rod 703, the bottom end of the first piston rod 703 passes through the air cylinder 702 and is fixedly connected to a first fixing plate 704, and a fixing component 705 is arranged on the surface of the first piston rod 703.

[0028] When grinding the mouth of the PE core tube, place the PE core tube on the support plate 701, and make the mouth of the PE core tube fit with one end of the grinding disc 4, start the electric push rod 6, and fill the gas cylinder 702 with gas. When the electric push rod 6 is started, the telescopic end of the electric push rod 6 will push the gas cylinder 702 to move downward, thereby driving the first piston rod 703, the first fixed plate 704 and the fixed assembly 705 to move downward synchronously. During this process, the inner wall of the first fixed plate 704 will first contact the surface of the PE core tube. At this time, the electric push rod 6 continues to push the gas cylinder 702 to move downward and drive the fixed assembly 705 to operate.

[0029] After the fixing mechanism 7 has fixed the PE core tube, the staff starts the motor 3 through the controller, and the output shaft of the motor 3 drives the grinding disc 4 to rotate and grind the pipe mouth of the PE core tube.

[0030] It should be noted that the grinding disc 4 in the above description is a device with relatively mature application in the prior art, and the specific model can be selected according to actual needs.

[0031] like Figure 2 and Figure 3 As shown, the fixing assembly 705 includes two arc-shaped plates 7051 fixedly connected to the lower end of the surface of the first piston rod 703, the inner wall of the arc-shaped plate 7051 is fixedly connected with two cylinders 7052, a mounting pipe 7053 is arranged between the two cylinders 7052, a connecting pipe 7054 is arranged between the mounting pipe 7053 and the gas storage cylinder 702, the inner wall of the cylinder 7052 is slidably connected with a second piston rod 7055, one end of the two second piston rods 7055 both penetrates the cylinder 7052 and is hinged with a second fixing plate 7056. The connecting pipe 7054 is a hose. The two second fixing plates 7056 are symmetrical with respect to the center of the first fixing plate 704.

[0032] When the inner wall of the first fixing plate 704 contacts the surface of the PE winding core tube, the two second fixing plates 7056 are located on both sides of the upper end of the surface of the PE winding core tube, and the two second fixing plates 7056 are inclined. At this time, when the electric push rod 6 continues to push the gas storage cylinder 702 to move downward, under the interaction force between the PE winding core tube and the electric push rod 6, the first fixing plate 704 and the first piston rod 703 remain stationary, and the gas storage cylinder 702 moves downward. At this time, the gas in the gas storage cylinder 702 will be squeezed by the first piston rod 703, and the gas storage cylinder 702 is After being squeezed, the gas in the two mounting tubes 7053 will enter the two mounting tubes 7053 through the two connecting tubes 7054 at the same time. When the gas enters the mounting tubes 7053, it will enter the two cylinders 7052 at the same time and push the two second piston rods 7055 to move at the same time, thereby pushing the second fixing plate 7056 to move downward. When the second fixing plate 7056 is moving, the upper end of the other side of the second fixing plate 7056 will first contact the surface of the PE winding core tube. At this time, the second piston rod 7055 located at the top cannot continue to move, and the gas The gas cannot enter the upper cylinder 7052. At the same time, the gas continues to enter the lower cylinder 7052, pushing the lower second piston rod 7055 to continue moving. Since the upper side of the other side of the second fixing plate 7056 has already contacted the surface of the PE core tube, when the lower second piston rod 7055 continues to push the second fixing plate 7056, the second fixing plate 7056 will rotate within a small range under the action of the hinge. When the first fixing plate 704 contacts the surface of the PE core tube, the corresponding two second piston rods 7055 cannot move any further. At this time, the two second fixing plates 7056 complete the clamping and fixing of the PE core tube from both sides of the upper end of the surface of the PE core tube. At this time, under the action of the two second fixing plates 7056, the PE core tube is in a centered state between the first fixing plate 704 and the support plate 701, so that the first fixing plate 704 forms a centering force to fix the PE core tube. After the fixation is completed, the staff can close the electric push rod 6 through the controller.

[0033] like Figure 3 and Figure 4 As shown, the inner wall of the second fixing plate 7056 is provided with mounting grooves 7057 distributed in equal rows, and the inner wall of the mounting groove 7057 is slidably connected with a fixing block 7058, and one side of the fixing block 7058 penetrates the second fixing plate 7056. A first spring 7059 is fixedly connected between the other side of the fixing block 7058 and the inner wall of the mounting groove 7057.

[0034] When the second fixing plate 7056 fixes the PE core tube, the fixing block 7058 will first contact the surface of the PE core tube. When the middle part of the second fixing plate 7056 fixes the PE core tube, the fixing block 7058 located in the middle will shrink into the installation groove 7057 and squeeze the first spring 7059. The fixing blocks 7058 on both sides will contact the surface of the PE core tube under the action of the first spring 7059 to clamp the PE core tube.

[0035] like Figure 3 As shown, a second spring 70510 is sleeved on the surface of the second piston rod 7055 , one end of the second spring 70510 is fixedly connected to the inner wall of the cylinder 7052 , and the other end of the second spring 70510 is fixedly connected to the bottom end of the second piston rod 7055 .

[0036] When the second piston rod 7055 moves, the second spring 70510 will be squeezed. When the fixation of the PE core tube is released, the electric push rod 6 moves upward. At this time, the gas in the cylinder 7052 loses its squeezing. Under the action of the second spring 70510, the gas in the cylinder 7052 will flow back into the gas storage cylinder 702 again, so that the gas storage cylinder 702 returns to its initial state and drives the second fixed plate 7056 to reset.

[0037] like Figure 4 As shown, a rubber pad 70511 is fixedly connected to one side of the fixing block 7058, and the surface of the rubber pad 70511 is provided with line grooves distributed in equal rows. When the fixing block 7058 is pressed against the PE winding core tube, the surface of the rubber pad 70511 contacts the surface of the PE winding core tube.

[0038] like Figure 5 As shown, the middle groove of the support plate 701 is arc-shaped, and the inner wall of the support plate 701 is fixedly connected with a contact pad 7011, which is a rubber component. When the PE core tube is placed on the support plate 701, the surface of the PE core tube contacts the surface of the contact pad 7011, and the surface of the contact pad 7011 is provided with annular grooves.

[0039] like Figure 2 As shown, a cushion is fixedly connected to the inner wall of the first fixing plate 704, and the cushion is a rubber member. When the first fixing plate 704 fixes the PE winding tube, the surface of the cushion contacts the surface of the PE winding tube, thereby increasing the friction between the first fixing plate 704 and the surface of the PE winding tube.

[0040] When the utility model is in use, when grinding the mouth of the PE core tube, the PE core tube is placed on the support plate 701, and the mouth of the PE core tube is made to fit with one end of the grinding disc 4, and the electric push rod 6 is started to push the gas storage cylinder 702 to move downward, thereby driving the first piston rod 703, the first fixed plate 704 and the fixed assembly 705 to move downward synchronously. During this process, the inner wall of the first fixed plate 704 will first contact the surface of the PE core tube, and the electric push rod 6 will continue to push the gas storage cylinder 702 to move downward. At this time, the gas in the gas storage cylinder 702 is squeezed by the first piston rod 703, and the squeezed gas enters the cylinder 7052 at the same time through the connecting pipe 7054 and the installation pipe 7053, and pushes the second piston rod 7055 to move, thereby pushing the two second fixed plates 7 056 moves downward at the same time. During the movement of the second fixed plate 7056, the middle part of the second fixed plate 7056 is hinged with the corresponding two second piston rods 7055, which makes the middle part of the second fixed plate 7056 contact with the surface of the PE core tube and fix it. At the same time, multiple fixed blocks 7058 are pressed against the surface of the PE core tube under the action of the first spring 7059. Under the action of the two second fixed plates 7056, the PE core tube is in a centered state between the first fixed plate 704 and the support plate 701, so that the first fixed plate 704 forms a centered force to fix the PE core tube. After the fixation is completed, the electric push rod 6 is closed and the motor 3 is started. The output shaft of the motor 3 drives the grinding disc 4 to rotate to grind the pipe mouth of the PE core tube.

[0041] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
