Description

Technical Field

[0001] The utility model relates to production equipment for HDPE winding pipes, in particular to an axial straight rib winding installation frame. Background Art

[0002] HDPE corrugated pipes usually have qualified ring stiffness, but there may be unexpected bending when facing bending. For this reason, it is necessary to add axially parallel transverse ribs to increase the bending resistance. Traditional extruded corrugated pipes can extrude transverse ribs at the same time as the outer shell is extruded. However, because the design usually also designs circumferential reinforcement ribs for ring stiffness, the combination of the surrounding reinforcement ribs and the transverse ribs will cause the extruded transverse ribs to be discontinuous, thereby reducing the maximum bending resistance of the transverse ribs. Due to its production process, traditional wound corrugated pipes cannot attach transverse ribs while winding. If the transverse ribs need to be reattached after cutting, the production speed will be reduced, thereby losing the production advantage of wound corrugated pipes.

[0003] In response to the demand for transverse ribs, a ring-shaped die with a surround structure is designed and the die is synchronized with the winding speed. Since the winding output is axial and has the same rotation speed, the cooperation between the ring-shaped die and the winding machine can meet the production needs of attaching and extruding straight ribs on the outer surface of the winding tube.

[0004] The surrounding track of the annular head usually needs to form an injection channel, which makes it impossible to directly input power from the periphery. It is necessary to design an auxiliary frame for installing the annular head and using the frame to drive the annular head to rotate. Summary of the invention

[0005] The utility model designs an axial straight rib winding disk mounting frame for supporting the rotation of the annular machine head and driving the annular machine head to rotate at the same time, aiming at the fact that the annular machine head cannot directly input the power driving force due to structural reasons.

[0006] An axial straight rib winding installation frame, adapted for the output end of winding tube production equipment, comprises:

[0007] The main support wheel is in the form of a circular ring and is fixed on the output axis of the winding tube production equipment through the support wheel fixing frame;

[0008] The side support wheel is in the form of a circular ring and is fixed to the output axis of the winding tube production equipment through a frame;

[0009] The main support wheel, the side support wheel and the output axis of the winding tube production equipment are coaxial;

[0010] A plurality of axial through holes are arranged on the circumferential surfaces of the main support wheel and the side support wheel, and the axial through holes form a circular array about the center of the support wheel where they are located;

[0011] The connecting screw passes through the axial through holes of the main support wheel and the side support wheel to connect the main support wheel and the side support wheel, so that the side support wheel rotates with the main support wheel. The equipment to be driven by the main support wheel is arranged between the main support wheel and the side support wheel.

[0012] It is supported by the main support wheel and the side support wheel and passes through the ring head (the extruder is connected to the ring head here). A single main support wheel can also be used to connect the ring head, but that will cause the main support wheel to produce axial gravity offset and cause the axis to turn.

[0013] Preferably, the number of axial through holes arranged on the main support wheel is greater than or equal to 2.

[0014] The more rings of the axial through hole, the more sizes of the ring heads that can be adapted. In contrast, the side support wheels need to be selected according to the diameter of the selected axial through hole. For the case of multiple rings, the side support wheels on both sides of the main support wheel can be selected with different diameters to facilitate installation.

[0015] As a preference, the front and back sides of the main support wheel are provided with convex rings of the same diameter; the front and back support wheel fixing frames are mirror images and relatively fixed;

[0016] The cross section of the bracket wheel fixing frame is a side-mounted concave structure, and the convex ring is inserted into the groove of the bracket wheel fixing frame;

[0017] The servo motor provides power to the main support wheel and is driven by the main support wheel through a pulley.

[0018] As a preference, grooves are provided on the front and back sides of the main support wheel with the same diameter, and the grooves are in the form of a circular ring on the main support wheel; the front and back support wheel fixing frames are mirror images and relatively fixed;

[0019] The cross section of the bracket wheel fixing frame is a side-mounted convex structure, the convex edge matches the groove, and the convex edge is stuck in the groove of the main bracket wheel;

[0020] The servo motor provides power to the main support wheel and is driven by the main support wheel through a pulley.

[0021] Preferably, the main support wheel is concentrically divided into an outer ring and an inner ring, wherein the axial thickness of the outer ring is greater than that of the inner ring, and the axial through hole is arranged on the inner ring;

[0022] The front and back sides of the outer ring are provided with grooves of the same diameter, and the front and back bracket wheel fixing frames are mirror images and relatively fixed;

[0023] The single-sided support wheel fixing frame includes at least 4 support rollers, the support rollers are arranged in a ring array about the axis of the main support wheel, and the support rollers are all inserted into the grooves;

[0024] The servo motor provides power to the main support wheel and is driven by the main support wheel through a pulley.

[0025] Preferably, the main support wheel is concentrically divided into an outer ring and an inner ring, the axial through hole is arranged on the inner ring, and the motor rotor is arranged on the outer ring;

[0026] The inner ring of the bracket wheel fixing frame is provided with a stator, and the rotor cooperates with the stator to drive the main bracket wheel to rotate.

[0027] Preferably, the frame of the side support wheel includes at least one pair of supporting rollers;

[0028] The supporting roller is arranged in the lower half circle of the side bracket wheel and is tangent to the outer periphery of the side bracket wheel. The width of the supporting roller is greater than the thickness of the side bracket wheel, and a groove is opened on the wheel surface of the supporting roller so that the side bracket wheel is stuck in the groove, thereby reducing the axial deviation of the side bracket wheel.

[0029] Preferably, pressure wheel mounting holes are arranged on the radial surface of the side support wheel, and the pressure wheel mounting holes are arranged at equal intervals.

[0030] The beneficial effects of the utility model are: it can effectively drive any annular components and facilitate expansion. It can still maintain stability when driving heavy annular components containing fluids. A synchronous pressure wheel assembly is attached to the annular head, so that the extruded transverse ribs can be better attached to the winding tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0041] like Figure 1 , Figure 2 and Figure 3 As shown in (a), the axial straight rib winding disk installation frame is suitable for the output end of the winding tube production equipment, comprising:

[0042] The main support wheel 101 is in the form of a circular ring and is fixed to the output axis of the winding tube production equipment through the support wheel fixing frame 100;

[0043] The side support wheel 300 is in the form of a circular ring and is fixed on the output axis of the winding tube production equipment through a frame;

[0044] The main support wheel, the side support wheel and the output axis of the winding tube production equipment are coaxial;

[0045] A plurality of axial through holes are arranged on the circumferential surfaces of the main support wheel and the side support wheel, and the axial through holes form a circular array about the center of the support wheel where they are located;

[0046] The connecting screw passes through the axial through holes of the main support wheel and the side support wheel to connect the main support wheel and the side support wheel, so that the side support wheel rotates with the main support wheel. The equipment to be driven by the main support wheel is arranged between the main support wheel and the side support wheel.

[0047] It is supported by the main support wheel and the side support wheel and passes through the annular head 200 (the extruder is connected to the annular head here). A single main support wheel can also be used to connect the annular head, but that will cause the main support wheel to produce axial gravity offset and cause the axis to turn.

[0048] Usually, the annular head 200 is set on the side of the winding tube production equipment, and 400 is marked with a pressing wheel device. Since the thermoplastic cooling and shaping of the annular head base still needs to be pressed, a pressing wheel device 400 is set on the other side of the main support wheel for pressing the transverse ribs.

[0049] In this embodiment, the annular head 200 and the pressing wheel device 400 are both existing devices.

[0050] The front and back sides of the main support wheel are provided with convex rings of the same diameter; the front and back support wheel fixing frames are mirror images and relatively fixed;

[0051] The cross section of the support wheel fixing frame is a side-mounted concave structure 110, and the convex ring is clamped into the groove of the support wheel fixing frame;

[0052] The servo motor provides power to the main support wheel and is driven by the main support wheel through a pulley 102.

[0053] The number of the axial through holes on the main support wheel is greater than or equal to 2.

[0054] The more rings of the axial through hole, the more sizes of the ring heads that can be adapted. In contrast, the side support wheels need to be selected according to the diameter of the selected axial through hole. For the case of multiple rings, the side support wheels on both sides of the main support wheel can be selected with different diameters to facilitate installation.

[0055] The frame of the side support wheel includes at least one pair of supporting rollers 301; the supporting rollers are arranged in the lower half of the side support wheel, tangent to the outer periphery of the side support wheel, the width of the supporting rollers is greater than the thickness of the side support wheel, and a groove is provided on the wheel surface of the supporting rollers, so that the side support wheel is stuck in the groove, thereby reducing the axial deviation of the side support wheel. An axial through hole 300-1 is provided on the annular surface of the side support wheel for use in connecting the screw. Example

[0056] like Figure 3 The difference between this embodiment shown in (b) and embodiment 1 is that the main support wheel is fixed in a different way. The front and back sides of the main support wheel 101 are provided with grooves of the same diameter, and the grooves are in the form of a ring on the main support wheel; the front and back support wheel fixing frames are mirror images and relatively fixed;

[0057] The cross section of the support wheel fixing frame is a side-mounted convex structure 120, the convex edge matches the groove, and the convex edge is stuck in the groove of the main support wheel;

[0058] The servo motor provides power to the main support wheel and is driven by the main support wheel through a pulley 102. Example

[0059] like Figure 4 and Figure 5 The difference between the present embodiment shown and embodiment 1 is that the main support wheel is fixed in a different manner.

[0060] The main support wheel 101 is concentrically divided into an outer ring and an inner ring, wherein the axial thickness of the outer ring is greater than that of the inner ring, and the axial through hole is provided on the inner ring;

[0061] The front and back sides of the outer ring are provided with grooves of the same diameter, and the front and back bracket wheel fixing frames are mirror images and relatively fixed;

[0062] The single-sided support wheel fixing frame includes 6 support rollers 131, which are arranged in a ring array about the axis of the main support wheel, and the support rollers are all inserted into the grooves;

[0063] The servo motor provides power to the main support wheel and is driven by the main support wheel through a pulley 102. Example

[0064] The difference between this embodiment and embodiment 1 is that the main support wheel is driven in a different way. The main support wheel is concentrically divided into an outer ring and an inner ring, the axial through hole is set on the inner ring, and the outer ring is set as a motor rotor; the inner ring of the support wheel fixed frame is provided with a stator, and the rotor cooperates with the stator to drive the main support wheel to rotate. This embodiment adopts a driving method similar to a stepper motor, omitting the external motor, and the overall structure is more compact. Example

[0065] like Figure 7 and Figure 8 The pressure wheel device 400 in the embodiment shown does not adopt the existing one, but is obtained by modifying the side bracket wheel provided by the present application. By using the wheel body 401 of the additional side bracket wheel, and setting the pressure wheel mounting holes on the radial surface of the side bracket wheel, the pressure wheel mounting holes are arranged at equal intervals. Then use the existing pressure wheel 402, and insert the pressure wheel into the pressure wheel mounting hole as required. A pressure wheel device 400 can be assembled. As a pressure wheel device, the wheel body surface of the side bracket wheel has a conventional axial through hole 401-1. Similarly, the same as the side bracket wheel, the wheel body of the side bracket wheel in this embodiment needs a supporting roller 403 for support and positioning.

[0066] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
