[0001] The present invention relates to the field of extrusion heads, in particular to a hose extrusion head and a method for manufacturing a hose. Background Art

[0002] A hose is a flexible and bendable tubular object. A hose extruder is a professional equipment used to produce plastic hoses. Its main function is to heat, melt, extrude, and cool the plastic raw materials to form the required hose products.

[0003] The existing hose extruder head has the following problems when in use: the existing extruder is equipped with a single head of a certain specification type, which limits the use range of the extruder, and many parts need to be replaced when replacing the head, making the disassembly and assembly work more cumbersome.

[0004] Therefore, it is necessary to invent a hose extrusion die head and method for making a hose to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a hose extrusion die and method for manufacturing hoses, so as to solve the problem that the existing extruder proposed in the above background technology is equipped with a single die of one specification type, which limits the scope of use of the extruder and requires more parts to be replaced when replacing the die, resulting in cumbersome disassembly and assembly work.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: a hose extruder head for manufacturing a hose, comprising a frame, a hopper is installed on the top of the frame, and the hopper is connected to the barrel, and the discharge end of the barrel can be matched with the head body, the frame is internally embedded with a head storage frame, and the outer wall of the head storage frame is fixedly connected to a motor, and the output shaft of the motor is transmission-connected to a drive shaft, the outer wall of the drive shaft is fixedly sleeved with a head disk, the head disk is movable inside a movable groove reserved inside the head storage frame, and the head body is movably installed inside the head disk, and the head storage frame is provided with a notch, further comprising:

[0007] The toggle assembly, the outer ring of the head body is provided with a thread, and the outer ring of the thread is threadedly connected with the thread groove reserved inside the head disk;

[0008] The mounting assembly is configured such that a threaded ring is fixedly connected to the outer wall of the discharge end, and the threaded ring is threadedly connected to the second threaded groove reserved inside the main body of the machine head.

[0009] Preferably, a toggle slot is reserved at the end of the machine head body close to the motor, so as to facilitate toggling the machine head body through the toggle slot;

[0010] The two ends of the head body protrude from the head plate, and the two end walls of the head body are in contact with the inner walls of the groove reserved inside the head storage frame and are in sliding connection, which facilitates the stable movement of the head body inside the head storage frame.

[0011] Preferably, there are four groups of head bodies, and the four groups of head bodies are distributed in a ring shape at equal angles inside the head disk. In this way, four groups of head bodies with different specifications can be switched and installed with the barrel at any time, ensuring a wider range of application of the extrusion device.

[0012] Preferably, the interior of the thread groove 1 is connected to the annular groove, and the inner wall of the annular groove is in contact with the outer wall of the annular block to achieve a sliding connection, and the inner ring side wall of the annular block does not contact the thread set on the outer ring of the head body.

[0013] Preferably, the inner wall of the annular block is fixedly connected with two limit blocks which are symmetrically arranged with reference to the central axis of the annular block as the symmetry axis, and the limit blocks are square, and the ends of the limit blocks extend into the limit grooves reserved inside the head body, and the outer walls of the limit blocks are in contact with the inner walls of the limit grooves and are connected in a reciprocating sliding manner. In this way, when the head body moves to the extreme position, the inner wall of the limit groove inside the head body abuts against the limit blocks, and the head body no longer has space for rotational movement.

[0014] Preferably, both ends of the limiting groove are in a closed state.

[0015] Preferably, the notch is in a "U" shape, and the notch is movably connected to the main body of the machine head, so that the main body of the machine head can be conveniently connected and installed with the end of the barrel through the notch during movement.

[0016] The present invention also provides a hose extrusion method for manufacturing a hose, using the above-mentioned hose extrusion die head for manufacturing a hose, and the specific operating steps are as follows:

[0018] Step 2: The die body is rotated by toggling the toggle groove. The die body, which is threadedly connected to the die plate, moves during rotation. During the movement of the die body, the threaded ring fixedly connected to the end wall of the discharge end in the barrel is connected. At this time, the discharge end and the die body are connected. The entire extrusion device is assembled and can be used for the production and processing of the hose.

[0019] Step 3: The mixed rubber raw materials will be fed into the hopper of the extruder. In the barrel inside the extruder, the rubber material will be subjected to high temperature and high pressure to be heated and plasticized. The plasticized rubber material will be pushed by the screw inside the extruder barrel and extruded through the die of the head body to form the required hose shape;

[0020] Step 4: Subsequently rotate the machine head body so that it rotates and moves toward the direction of the motor. When the machine head body moves to the extreme position so that the inner wall of the limit groove abuts against the limit block, the machine head body can no longer be rotated. At this time, the relative position of the machine head body and the machine head disk returns to the initial state, thus ensuring that the machine head disk can store the machine head body into the machine head storage frame when rotating.

[0021] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0022] 1. The present invention starts the motor to drive the die plate to rotate 90 degrees each time, and the die bodies of different specifications and sizes move to the notch reserved inside the die storage frame. When the die body is rotated, the die body moves and connects with the threaded ring fixedly connected to the end wall of the discharge end in the barrel. At this time, the discharge end and the die body are connected. The entire extrusion device is assembled and can be used for the production and processing of hoses, ensuring the rapid disassembly and assembly of multiple sets of die heads.

[0023] 2. Subsequently, the machine head body is rotated to move toward the direction of the motor. When the machine head body moves to the extreme position so that the inner wall of the limit groove abuts against the limit block, the machine head body can no longer be rotated. The relative position of the machine head body and the machine head disk is restored to the initial state. This ensures that the machine head disk can store the machine head body into the machine head storage frame when rotating, so as to facilitate the storage of the machine head and facilitate the next use.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] The present invention provides Figure 1-6 The hose extruder head for manufacturing a hose shown in the figure includes a frame 1, a hopper 2 is installed on the top of the frame 1, and the hopper 2 is connected to the barrel 3, and the discharge end 4 of the barrel 3 can be matched with the head body 9. The frame 1 is internally fitted with a head storage frame 5, and the outer wall of the head storage frame 5 is fixedly connected to a motor 6, and the output shaft of the motor 6 is transmission-connected to a drive shaft 7, the outer wall of the drive shaft 7 is fixedly sleeved with a head disk 8, the head disk 8 is movable inside a movable groove 12 reserved inside the head storage frame 5, and the head body 9 is movably installed inside the head disk 8, and a notch 15 is provided inside the head storage frame 5, and further includes:

[0035] The outer ring of the toggle assembly 11 is provided with a thread 111, and the outer ring of the thread 111 is threadedly connected with a thread groove 112 reserved inside the head plate 8;

[0036] The mounting assembly 14 is fixedly connected to the outer wall of the discharge end 4 with a threaded ring 141 , and the threaded ring 141 is threadedly connected to the second threaded groove 142 reserved inside the head body 9 .

[0037] A toggle slot 10 is reserved at the end of the machine head body 9 close to the motor 6, so that the machine head body 9 can be easily toggled through the toggle slot 10;

[0038] The two ends of the head body 9 protrude from the head disk 8, and the two end walls of the head body 9 are in contact with the inner walls of the groove 13 reserved inside the head storage frame 5 and are in sliding connection, which facilitates the stable movement of the head body 9 inside the head storage frame 5.

[0039] There are four groups of head bodies 9, and the four groups of head bodies 9 are distributed in a ring shape at equal angles inside the head disk 8. In this way, four groups of head bodies 9 with different specifications can be switched and installed with the barrel 3 at any time, ensuring a wider range of application of the extrusion device.

[0040] The interior of the thread groove 112 is connected to the annular groove 113, and the inner wall of the annular groove 113 is in contact with the outer wall of the annular block 114 to achieve a sliding connection, and the inner ring side wall of the annular block 114 does not contact the thread 111 set on the outer ring of the head body 9.

[0041] The inner wall of the annular block 114 is fixedly connected with two limit blocks 115 which are symmetrically arranged with reference to the central axis of the annular block 114 as the symmetry axis, and the limit blocks 115 are square, and the ends of the limit blocks 115 extend into the limit grooves 116 reserved inside the head body 9. The outer wall of the limit block 115 is in contact with the inner wall of the limit groove 116 and is connected in a reciprocating sliding manner. In this way, when the head body 9 moves to the extreme position, the inner wall of the limit groove 116 inside the head body 9 abuts against the limit block 115, and the head body 9 no longer has space for rotational movement.

[0042] Both ends of the limiting groove 116 are in a closed state.

[0043] The notch 15 is U-shaped and is movably connected to the die body 9 . The die body 9 can be conveniently connected and installed with the end of the barrel 3 through the notch 15 during movement.

[0044] The present invention also provides a hose extrusion method for manufacturing a hose, using the above-mentioned hose extrusion die head for manufacturing a hose, and the specific operating steps are as follows:

[0045] Step 1: Start the motor 6 to drive the head plate 8 to rotate 90 degrees, and the head bodies 9 of different specifications and sizes move to the notch 15 reserved inside the head storage frame 5;

[0046] Step 2: The die body 9 is rotated by toggling the toggle slot 10. The die body 9, which is threadedly connected to the die plate 8, moves during rotation. During the movement of the die body 9, the threaded ring 141 fixedly connected to the end wall of the discharge end 4 in the barrel 3 is connected. At this time, the discharge end 4 and the die body 9 are connected. The entire extrusion device is assembled and can be used for the production and processing of the hose.

[0047] Step 3: The mixed rubber raw materials will be fed into the hopper 2 of the extruder. In the barrel 3 inside the extruder, the rubber materials will be subjected to high temperature and high pressure to be heated and plasticized. The plasticized rubber materials will be pushed by the screw inside the extruder barrel 3 and extruded through the die of the head body 9 to form the desired hose shape.

[0048] Step 4: Subsequently rotate the machine head body 9 so that the machine head body 9 rotates and moves toward the direction of the motor 6. When the machine head body 9 moves to the extreme position so that the inner wall of the limit groove 116 abuts against the limit block 115, the machine head body 9 can no longer be rotated. At this time, the relative position of the machine head body 9 and the machine head disk 8 is restored to the initial state, thereby ensuring that the machine head disk 8 can store the machine head body 9 into the inside of the machine head storage frame 5 when rotating.

[0049] Working principle: When using a hose extruder head for manufacturing a hose, first start the motor 6, and the drive shaft 7 connected to the output shaft of the motor 6 rotates synchronously. The rotation of the drive shaft 7 drives the rotation of the head disk 8 fixed to the outer wall of the drive shaft 7. Four groups of head bodies 9 are installed on the head disk 8 at equal angles in a ring. In this way, when the head disk 8 rotates, it drives the four groups of head bodies 9 that are threadedly connected to the head disk 8 and distributed at equal angles in a ring to move synchronously in a ring. When the motor 6 drives the head disk 8 to rotate 90 degrees, the head bodies 9 of different specifications and sizes move to the notch 15 reserved inside the head storage frame 5. At this time, it is necessary to align the head body 9 with the head disk 8. When the discharge end 4 of the barrel 3 is engaged, the rotation of the head body 9 is toggled by the toggle groove 10, and the head body 9 threadedly connected to the head disk 8 moves during rotation. The head body 9 rotates in the direction of the barrel 3. During the movement of the head body 9, the threaded ring 141 fixedly connected to the end wall of the discharge end 4 of the barrel 3 is connected. During the continuous rotation of the head body 9, the threaded groove 142 reserved at the end of the head body 9 in the rotating movement state is threadedly connected to the threaded ring 141. At this time, the connection between the discharge end 4 and the head body 9 is completed, and the entire extrusion device is assembled and can be used for the production and processing of hoses.

[0050] At the same time, during the rotation of the head body 9, the annular block 114 and the limit block 115 fixedly connected to the inner wall of the annular block 114 match the limit groove 116 reserved inside the head body 9. When the head body 9 rotates, the limit block 115 and the annular block 114 rotate synchronously inside the annular groove 113, so that the annular block 114 and the limit block 115 do not affect the rotation of the head body 9. At the same time, when the head body 9 rotates and moves, the strip-shaped limit groove 116 reserved inside the head body 9 is slidably connected with the limit block 115, so that the rotational movement of the head body 9 is not affected. When the head body 9 moves to the extreme position, the inner wall of the limit groove 116 inside the head body 9 is against the limit block 115. After the connection, the head body 9 no longer has space for rotational movement. If the head body 9 is threadedly connected to the threaded ring 141 at this time, and the head body 9 can no longer move toward the direction of the barrel 3, it means that the threaded connection between the head body 9 and the threaded ring 141 is in place. When the head body 9 knob needs to be reset later, the rotation of the rotating head body 9 causes the head body 9 to rotationally move toward the direction of the motor 6. When the head body 9 moves to the extreme position so that the inner wall of the limit groove 116 abuts against the limit block 115, the head body 9 can no longer be rotated. At this time, the relative position of the head body 9 and the head disk 8 is restored to the initial state, thereby ensuring that the head disk 8 can store the head body 9 into the head storage frame 5 when it rotates.

[0051] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
