[0003] When the existing plastic hose forming machine discharges the hose, the die head diameter usually remains unchanged. When it is necessary to discharge hoses with different diameters, the die head needs to be replaced. During the replacement process, there is a die head replacement time, which affects the discharge efficiency of the hose. Summary of the invention

[0004] The object of the present invention is to provide an adjustable extrusion type plastic hose forming machine for cables to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an adjustable extrusion type cable plastic hose forming machine, comprising an extrusion conveying assembly, on the outer wall of which a heater for heating plastic particles is installed; An adjustable die head for forming a plastic hose is installed at the discharge port of the extrusion conveying assembly, and the adjustable die head is set to be adjustable and is used for discharging hoses of different calibers; Conveying components are respectively installed on both sides of the discharge path of the adjustable die head, and the conveying components are used for stably conveying the formed plastic hose and for forming the threads on the outer wall of the hose.

[0006] In this embodiment, the purpose of the above-mentioned setting is that the plastic particles enter through the feed port of the extrusion conveying component, the heater heats the outer wall of the extrusion conveying component, so that the plastic particles are gradually heated in the barrel, from solid particles to plastic viscous fluid, and then pushed to the adjustable die head. The adjustable die head adjusts the discharge diameter according to needs. The adjustable setting of the die head adapts to the production needs of hoses with different diameters. The formed plastic hose is stably conveyed through the conveying component, and the conveying component simultaneously forms threads on the outer wall of the hose; The heater usually includes a protective shell, a heating element, a circuit, a control device and a safety protection device. The protective shell is arranged on the outer wall of the conveying component, and the heating element is usually located inside the protective shell. The protective shell plays the role of fixing and protecting the heating element. The circuit provides power support for the control device, and the control device controls the equipment by controlling operations such as the on and off of the circuit. The heat transfer medium is used to transfer heat and transfer the heat generated by the heating element to the conveying component that needs to be heated. The safety protection device is usually connected in parallel in the circuit to ensure the high reliability and safety of the system.

[0007] Furthermore, the extrusion conveying assembly includes a shell, a motor is installed on the outer wall of the shell, an output shaft of the motor passes through the shell and extends to the inside of the shell, a spiral rod is installed on the output shaft of the motor, and the outer wall of the spiral rod is in contact with the inner wall of the shell; A feed port is arranged at the top of the shell, and a discharge port is arranged at one end of the shell away from the motor.

[0008] In this embodiment, the purpose of the above-mentioned setting is that when the motor is started, the output shaft of the motor drives the screw rod to rotate in the shell, and the plastic particles enter from the feed port on the top of the shell. The rotation of the screw rod causes the plastic particles to move along the spiral groove of the screw rod toward the discharge port. Since the outer wall of the screw rod and the inner wall of the shell fit each other, the plastic particles are compressed during the movement and are gradually plasticized by the heat after being heated by the heater. Under the continuous conveyance of the screw rod, the material passes through the discharge port.

[0009] Furthermore, the end of the shell away from the motor is configured to be conical, the discharge port is configured to be a small hole, and a plurality of the small holes are evenly arranged in a ring shape on the outer wall of one end of the shell.

[0010] In this embodiment, the purpose of the above arrangement is that the setting of the cone of the shell and the small holes helps the plasticized plastic to be initially shaped into strips so that it can be evenly output to the adjustable die head.

[0011] Furthermore, the adjustable die head includes a shell, which is connected to an outer wall of one end of the shell and communicated with the discharge port; One end of the shell, near the middle of the discharge port, is connected to a conical column, the outer wall of the shell is connected to two fixing rods, and the ends of the two fixing rods away from the shell are connected to a tube body; The tube body and the conical column leave an inner ring gap for a small-diameter hose to discharge materials.

[0012] In this embodiment, the purpose of the above arrangement is that the conical column is used to guide the material entering the housing.

[0013] Furthermore, an outer ring gap is left between the inner wall of one end of the shell and the outer wall of the tube body, and the diameter of the outer ring gap is larger than the inner ring gap.

[0014] In this embodiment, the purpose of the above arrangement is that the diameter of the outer ring gap is larger than that of the inner ring gap, and is different from the diameter of the inner ring gap, so that two hoses with different diameters can be used for discharging materials.

[0015] Furthermore, a second movable shell for opening and closing the outer ring gap is slidably connected to the outer wall of the tube body, the outer wall of the second movable shell is connected to the tube body, and one end of the tube body is connected to a ring for opening and closing the inner ring gap.

[0016] In this embodiment, the purpose of the above arrangement is that when the output hose diameter needs to be adjusted, the second movable shell is moved, and the edge of one end of the second movable shell is distanced from the inner wall of the outer shell, and the ring moves at the same time to close the inner ring gap, thereby guiding the material to the outer ring gap.

[0017] Furthermore, a sliding frame is connected to the outer wall of the second movable shell, and a sliding groove is provided on the outer wall of the outer shell; The top of the sliding frame is slidably connected to the sliding groove, and the sliding groove is closed during the sliding process; A first movable shell is connected to the outer wall of the sliding frame, and the first movable shell is used to close the inner port of the sliding groove of the outer shell; A screw rod is rotatably connected to the outer wall of the shell, and the screw rod penetrates the top of the sliding frame and is threadedly connected.

[0018] In this embodiment, the purpose of the above arrangement is that, through the rotation of the screw rod, since the screw rod penetrates the top of the sliding frame and is threadedly connected, the sliding frame will slide along the sliding groove on the outer wall of the shell. The sliding frame drives the first movable shell and the second movable shell to move, the ring can open and close the inner ring gap, and the second movable shell can open and close the outer ring gap. When the second movable shell opens the outer ring gap, the ring closes the inner ring gap, and the inner ring gap and the outer ring gap are in opposite states, thereby adjusting the caliber and shape of the discharge material, so that the plastic hose can be formed into different calibers.

[0019] Furthermore, the conveying assembly includes a support frame, the support frame is divided into two layers, a second motor is installed on the upper surface of the bottom layer of the support frame, and a conveyor belt is arranged on the upper surface of the top layer of the support frame; The output shaft of the second motor passes through the top of the support frame and extends to the inner side of the conveyor belt. A plurality of driving blocks are installed on the outer wall of the output shaft of the second motor. A plurality of bars that cooperate with the driving blocks are installed on the inner wall of the conveyor belt.

[0020] In this embodiment, the purpose of the above arrangement is that when the second motor is started, the driving block on its output shaft cooperates with the strips on the inner wall of the conveyor belt to drive each other, and at the same time, the transmission is transmitted through the transmission wheel and the transmission belt.

[0021] Furthermore, a plurality of mounting blocks are connected to the outer wall of the conveyor belt, an arc block is inserted into the mounting block, and a plurality of grooves are evenly arranged on the outer wall of one side of the arc block.

[0022] In this embodiment, the purpose of the above-mentioned setting is that the molded plastic hose enters the conveying assembly, and the mounting block connected to the conveyor belt is plugged with an arc block. The plug-in setting is used to replace the arc block to adapt to hoses of different calibers. The groove on the outer wall on one side of the arc block is used to thread the outer wall of the hose when the hose is in a plastic state, and at the same time, the conveyor belt stably conveys the molded plastic hose.

[0023] Furthermore, transmission wheels are provided on the lower surface of the top layer and the bottom layer of the support frame, one of the transmission wheels is connected to the middle rotating shaft of the driving block and is driven by the middle rotating shaft, a transmission belt is connected between the two transmission wheels, and a roller brush is installed on the other transmission wheel. When the arc block moves, the roller brush rotates to clean the outer wall of the arc block.

[0024] In this embodiment, the purpose of the above arrangement is that when the central axis rotates, it drives the two transmission wheels and the transmission belt to run, thereby driving the roller brush to rotate synchronously. When the arc block moves, the roller brush connected to the transmission wheel rotates to clean the outer wall of the arc block.

[0025] The present invention has the following beneficial effects: The present invention sets an adjustable die head and rotates a screw rod. Since the screw rod passes through the top of the sliding frame and is threadedly connected, the sliding frame slides along the sliding groove on the outer wall of the shell. The sliding frame drives the first movable shell and the second movable shell to move. The ring can open and close the inner ring gap, and the second movable shell can open and close the outer ring gap. When the second movable shell opens the outer ring gap, the ring closes the inner ring gap. The inner ring gap and the outer ring gap are in opposite states, thereby adjusting the caliber and shape of the discharge material, so that the plastic hose can be formed into different calibers. By adjusting the die head, different production requirements can be quickly adapted without replacing the entire mold, thereby reducing the time for replacing the die head and improving production efficiency.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In this embodiment, the purpose of the above arrangement is that the diameter of the outer ring gap is larger than that of the inner ring gap, and is different from the diameter of the inner ring gap, so that two hoses with different diameters can be used for discharging materials.

[0040] As an implementation method, Figure 2 - Figure 3 As shown, further: The outer wall of the tube body 203 is slidably connected to a second movable shell 208 for opening and closing the outer ring gap. The outer wall of the second movable shell 208 is connected to the tube body 203. One end of the tube body 203 is connected to a ring 204 for opening and closing the inner ring gap.

[0041] In this embodiment, the purpose of the above arrangement is that when the output hose diameter needs to be adjusted, the second movable shell 208 is moved, and the edge of one end of the second movable shell 208 is spaced from the inner wall of the outer shell 201, and the ring 204 is moved at the same time to close the inner ring gap, thereby guiding the material to the outer ring gap.

The sliding frame 206 drives the first movable shell 207 and the second movable shell 208 to move, the ring 204 can open and close the inner ring gap, and the second movable shell 208 can open and close the outer ring gap. When the second movable shell 208 opens the outer ring gap, the ring 204 closes the inner ring gap, and the inner ring gap and the outer ring gap are in opposite states, thereby adjusting the caliber and shape of the discharge material, so that the plastic hose can be formed into different calibers.

[0044] As an implementation method, Figure 6 As shown, further: The conveying assembly 4 includes a support frame 401, and the support frame 401 is divided into two layers. A second motor 402 is installed on the upper surface of the bottom layer of the support frame 401, and a conveyor belt 404 is arranged on the upper surface of the top layer of the support frame 401; The output shaft of the second motor 402 passes through the top of the support frame 401 and extends to the inner side of the conveyor belt 404 . A plurality of driving blocks 403 are installed on the outer wall of the output shaft of the second motor 402 . A plurality of bars that cooperate with the driving blocks 403 and drive the conveyor belt 404 are installed on the inner wall of the conveyor belt 404 .

[0045] In this embodiment, the purpose of the above arrangement is that when the second motor 402 is started, the driving block 403 on its output shaft cooperates with the strips on the inner wall of the conveyor belt 404 to drive each other, and at the same time, the transmission is transmitted through the transmission wheel and the transmission belt.

A plurality of grooves are evenly arranged on the outer wall of one side of the arc block 406 .

[0047] In this embodiment, the purpose of the above-mentioned setting is that the molded plastic hose enters the conveying component 4, and the mounting block 405 connected to the conveyor belt 404 is plugged with an arc block 406. The plug-in setting is used to replace the arc block 406 to adapt to hoses of different calibers.

At the same time, the conveyor belt 404 stably conveys the molded plastic hose.

[0048] As an implementation method, Figure 6 As shown, further: Transmission wheels are provided on the lower surface of the top layer of the support frame 401 and the bottom layer of the support frame 401, one of which is connected to the middle rotating shaft of the driving block 403 and is driven by the middle rotating shaft, a transmission belt is connected between the two transmission wheels, and a roller brush 5 is installed on the other transmission wheel.

[0050] When in use, the motor 101 is started, and the output shaft of the motor 101 drives the screw rod 102 to rotate in the housing 105. The plastic particles enter from the feed port 103 at the top of the housing 105. The rotation of the screw rod 102 causes the plastic particles to move along the spiral groove of the screw rod 102 toward the discharge port 104. Since the outer wall of the screw rod 102 and the inner wall of the housing 105 fit each other, the plastic particles are compressed during the movement, and are gradually plasticized by the heat from the heater 3. Under the continuous conveyance of the screw rod 102, the material passes through the discharge port 104. The conical shape of the housing 105 and the small holes are provided, which helps the plasticized plastic to be initially strip-shaped so that it can be evenly output to the adjustable die head 2. The conical column 205 is used to guide the material entering the housing 201. The diameter of the outer ring gap is larger than that of the inner ring gap. Different from the diameter of the inner ring gap, two hoses with different diameters can be used for discharging materials.

When the second movable shell 208 opens the outer ring gap, the ring 204 closes the inner ring gap, and the states of the inner ring gap and the outer ring gap are opposite, thereby adjusting the caliber and shape of the discharge material, so that the plastic hose can be formed into different calibers; The second motor 402 is started, and the driving block 403 on its output shaft cooperates with the strips on the inner wall of the conveyor belt 404 to drive each other. At the same time, the molded plastic hose enters the conveying assembly 4 through the transmission of the transmission wheel and the transmission belt. The mounting block 405 connected to the conveyor belt 404 is plugged with an arc block 406. The plug-in setting is used to replace the arc block 406 to adapt to hoses of different calibers. The groove on the outer wall of one side of the arc block 406 is used to thread the outer wall of the hose when the hose is in a plastic state. At the same time, the conveyor belt 404 stably transports the molded plastic hose. When the central shaft rotates, it drives the two transmission wheels and the transmission belt to run, thereby driving the roller brush 5 to rotate synchronously. When the arc block 406 moves, the roller brush 5 connected to the transmission wheel rotates to clean the outer wall of the arc block 406.
