Technical Field
[0001] The present invention relates to the technical field of plastic hoses for cables, and particularly to an adjustable extrusion type plastic hose forming machine for cables. Background Art
[0002] A plastic hose forming machine for cables is a device used to produce plastic hoses for cable protection. Plastic hoses for cables are a material widely used in wire and cable protection, with various properties and uses.
[0003] When the existing plastic hose forming machine discharges the hose, the die head diameter used is usually unchanged. When hoses of different diameters need to be discharged, the die head needs to be replaced. During the replacement process, there is a die head replacement time, which will affect the discharge efficiency of the hose. Summary of the Invention
[0004] The purpose 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 art.
[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:
[0006] The present invention is an adjustable extrusion type plastic hose forming machine for cables, including an extrusion and conveying assembly, and a heater for heating plastic particles is installed on the outer wall of the extrusion and conveying assembly;
[0007] An adjustable die head for plastic hose forming is installed at the discharge port of the extrusion and conveying assembly. The adjustable die head is set to be adjustable for discharging hoses of different diameters;
[0008] Conveying assemblies are respectively installed on both sides of the discharge path of the adjustable die head. The conveying assemblies are used for stably conveying the formed plastic hoses and simultaneously for forming threads on the outer wall of the hoses.
[0009] In this embodiment, the purpose of the above settings is that plastic particles enter through the feed port of the extrusion and conveying assembly, and the heater heats the outer wall of the extrusion and conveying assembly, so that the plastic particles are gradually heated in the barrel, heated from solid particle form to plastic viscous fluid, and then pushed towards the adjustable die head. The adjustable die head adjusts the discharge diameter according to needs, and the adjustable setting of the die head adapts to the production requirements of hoses of different diameters. The formed plastic hoses are stably conveyed through the conveying assemblies, and the conveying assemblies simultaneously form threads on the outer wall of the hoses;
[0010] The heater generally includes a protective housing, a heating element, a circuit, a control device, and a safety protection device. The protective housing is disposed on the outer wall of the conveying assembly. The heating element is usually located inside the protective housing. The protective housing serves to fix and protect the heating element. The circuit provides power support for the control device. The control device realizes the control of the equipment by controlling operations such as the on / 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 assembly that needs to be heated. The safety protection device is usually connected in parallel to the circuit to ensure the high reliability and safety of the system.
[0011] Further, the extrusion conveying assembly includes a housing. An electric motor is installed on the outer wall of the housing. The output shaft of the electric motor penetrates through the housing and extends into the interior of the housing. A screw rod is installed on the output shaft of the electric motor. The outer wall of the screw rod is in mutual contact with the inner wall of the housing.
[0012] A feed inlet is provided at the top of the housing. An outlet is provided at one end of the housing away from the electric motor.
[0013] In this embodiment, the purpose of the above settings is that when the electric motor starts, the output shaft of the electric motor drives the screw rod to rotate inside the housing. Plastic particles enter from the feed inlet at the top of the housing. The rotation of the screw rod causes the plastic particles to move along the helical groove of the screw rod towards the outlet. Since the outer wall of the screw rod is in mutual contact with the inner wall of the housing, the plastic particles are compressed during the movement and are simultaneously affected by the heat after being heated by the heater, gradually becoming plasticized. Under the continuous conveying of the screw rod, the material passes through the outlet.
[0014] Further, one end of the housing away from the electric motor is set to be conical, and the outlet is set to be a small hole. A plurality of the small holes are uniformly arranged in a ring shape on the outer wall of one end of the housing.
[0015] In this embodiment, the purpose of the above settings is that the conical shape of the housing and the small holes help to initially form the plasticized plastic into a strip shape, enabling it to be evenly output to the adjustable die head.
[0016] Further, the adjustable die head includes a housing. The housing is connected to the outer wall of one end of the housing and is in communication with the outlet.
[0017] At the middle of one end of the housing, close to the outlet, a conical column is connected. Two fixing rods are connected to the outer wall of the housing. The ends of the two fixing rods away from the housing are connected to a pipe body.
[0018] An inner ring gap for discharging through a small-diameter hose is left between the pipe body and the conical column.
[0019] In this embodiment, the purpose of the above settings is that the conical column is used to guide the material entering the housing.
[0020] Further, there is an outer ring gap left between the inner wall at one end of the outer shell and the outer wall of the pipe body, and the diameter of this outer ring gap is larger than that of the inner ring gap.
[0021] In this embodiment, the purpose of the above setting is that 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, hoses with two different diameters can be used for discharging materials.
[0022] Further, a second movable shell for opening and closing the outer ring gap is slidably connected to the outer wall of the pipe body. A pipe body is connected to the outer wall of the second movable shell, and a ring is connected to one end of the pipe body for opening and closing the inner ring gap.
[0023] In this embodiment, the purpose of the above setting is that when it is necessary to adjust the diameter of the output hose, move the second movable shell. A distance is generated between the edge at one end of the second movable shell and the inner wall of the outer shell, and the ring moves simultaneously to close the inner ring gap, thereby guiding the material to the outer ring gap.
[0024] Further, a sliding frame is connected to the outer wall of the second movable shell, and a sliding groove is formed on the outer wall of the outer shell;
[0025] The top of the sliding frame is slidably connected to the sliding groove and closes the sliding groove during the sliding process;
[0026] 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;
[0027] A lead screw is rotatably connected to the outer wall of the outer shell, and the lead screw passes through the top of the sliding frame and is threadedly connected.
[0028] In this embodiment, the purpose of the above setting is that by rotating the lead screw, since the lead screw passes through 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 outer 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 states of the inner ring gap and the outer ring gap are opposite, thereby adjusting the discharge caliber and shape and making the plastic hose into different calibers.
[0029] Further, 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;
[0030] The output shaft of the second motor penetrates 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, and a plurality of strip blocks that cooperate with the driving blocks for driving are installed on the inner wall of the conveyor belt.
[0031] In this embodiment, the purpose of the above setting is that when the second motor is started, the driving blocks on its output shaft cooperate with the strip blocks on the inner wall of the conveyor belt for driving. At the same time, through the transmission of the transmission wheel and the transmission belt.
[0032] Furthermore, a plurality of mounting blocks are connected to the outer wall of the conveyor belt. An arc-shaped block is inserted into the mounting block, and a plurality of grooves are evenly arranged on one outer wall of the arc-shaped block.
[0033] In this embodiment, the purpose of the above setting is that after the formed plastic hose enters the conveying assembly, the mounting blocks connected to the conveyor belt are inserted with arc-shaped blocks. The insertion setting is used to replace the arc-shaped blocks to adapt to hoses of different diameters. The grooves on one outer wall of the arc-shaped block perform thread forming on the outer wall of the hose when the hose is in a plastic state. At the same time, the conveyor belt stably conveys the formed plastic hose.
[0034] Furthermore, transmission wheels are provided on the lower surface of the top layer of the support frame and the bottom layer of the support frame. One of the transmission wheels is connected to the central shaft of the driving block and is driven by the central 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-shaped block moves, the roller brush rotates to clean the outer wall of the arc-shaped block.
[0035] In this embodiment, the purpose of the above setting is that when the central shaft rotates, it drives the two transmission wheels and the transmission belt to operate, thereby driving the roller brush to rotate synchronously. When the arc-shaped block moves, the roller brush connected to the transmission wheel rotates to clean the outer wall of the arc-shaped block.
[0036] The present invention has the following beneficial effects:
[0037] Through the setting of the adjustable die head in the present invention, by rotating the lead screw, since the lead screw penetrates through 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 housing. 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 states of the inner ring gap and the outer ring gap are opposite, so as to adjust the outlet diameter and shape, and make the plastic hose form different diameters. By adjusting the die head, it is possible to quickly adapt to different production requirements without replacing the entire mold, thereby reducing the time for replacing the die head and improving production efficiency.
[0038] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0049] The present invention relates to an adjustable extrusion type plastic hose forming machine for cables, as Figure 1 - Figure 6 shown, which includes an extrusion and conveying assembly 1, and a heater 3 for heating plastic particles is installed on the outer wall of the extrusion and conveying assembly 1;
[0050] An adjustable die head 2 for forming plastic hoses is installed at the discharge port of the extrusion and conveying assembly 1. The adjustable die head 2 is set to be adjustable and is used for discharging hoses of different calibers;
[0051] Conveying assemblies 4 are respectively installed on both sides along the discharge path of the adjustable die head 2. The conveying assemblies 4 are used for stably conveying the formed plastic hoses and at the same time for forming threads on the outer wall of the hoses.
[0052] In this embodiment, the purpose of the above settings is that plastic particles enter through the feed port 103 of the extrusion and conveying assembly 1, and the heater 3 heats the outer wall of the extrusion and conveying assembly 1, so that the plastic particles are gradually heated in the barrel, heated from solid particle state to plastic viscous fluid, and then pushed towards the adjustable die head 2. The adjustable die head 2 adjusts the discharge caliber according to needs. The adjustable setting of the die head adapts to the production requirements of hoses of different calibers. The formed plastic hoses are stably conveyed through the conveying assemblies 4, and the conveying assemblies 4 simultaneously form threads on the outer wall of the hoses;
[0053] The heater 3 generally 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 assembly 4. The heating element is usually located inside the protective shell. The protective shell plays a role in fixing and protecting the heating element. The circuit provides power support for the control device. The control device realizes the control of the equipment by controlling the on-off of the circuit and other operations. The heat transfer medium is used to transfer heat and transfer the heat generated by the heating element to the conveying assembly 4 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.
[0054] As an implementation manner, as Figure 5 shown, further:
[0055] The extrusion and conveying assembly 1 includes a housing 105. A motor 101 is installed on the outer wall of the housing 105. The output shaft of the motor 101 penetrates through the housing 105 and extends to the inside of the housing 105. A screw rod 102 is installed on the output shaft of the motor 101. The outer wall of the screw rod 102 is in mutual fit with the inner wall of the housing 105;
[0056] A feed port 103 is arranged at the top of the housing 105, and a discharge port 104 is arranged at one end of the housing 105 away from the motor 101.
[0057] In this embodiment, the purpose of the above settings is that when the motor 101 starts, the output shaft of the motor 101 drives the screw rod 102 to rotate within the housing 105. 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 helical groove of the screw rod 102 towards the discharge port 104. Since the outer wall of the screw rod 102 fits snugly against the inner wall of the housing 105, the plastic particles are compressed during movement and are simultaneously subjected to the heat from the heater 3, gradually becoming plasticized. With the continuous conveyance of the screw rod 102, the material passes through the discharge port 104.
[0058] As an implementation manner, as Figure 5 shown, furthermore:
[0059] One end of the housing 105 away from the motor 101 is set to be conical, and the discharge port 104 is set to be a small hole. A number of small holes are evenly arranged in a ring on the outer wall of one end of the housing 105.
[0060] In this embodiment, the purpose of the above settings is that the conical shape of the housing 105 and the small holes help to initially form the plasticized plastic into a strip shape, enabling it to be evenly output to the adjustable die head 2.
[0061] As an implementation manner, as Figure 2 - Figure 3 shown, furthermore:
[0062] The adjustable die head 2 includes an outer shell 201, which is connected to the outer wall of one end of the housing 105 and is in communication with the discharge port 104;
[0063] At one end of the housing 105, near the middle of the discharge port 104, a conical column 205 is connected. Two fixing rods 202 are connected to the outer wall of the housing 105, and a pipe body 203 is connected to the ends of the two fixing rods 202 away from the housing 105;
[0064] An inner ring gap for discharging through a small-diameter hose is left between the pipe body 203 and the conical column 205.
[0065] In this embodiment, the purpose of the above settings is that the conical column 205 is used to guide the material entering the outer shell 201.
[0066] As an implementation manner, as Figure 2 - Figure 3 shown, furthermore:
[0067] An outer ring gap is left between the inner wall of one end of the outer shell 201 and the outer wall of the pipe body 203, and the diameter of this outer ring gap is larger than that of the inner ring gap.
[0068] In this embodiment, the purpose of the above setting is that 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, hoses with two different diameters can be used for discharging materials.
[0069] As an implementation manner, as Figure 2 - Figure 3 shown, furthermore:
[0070] A second movable shell 208 for opening and closing the outer ring gap is slidably connected to the outer wall of the pipe body 203. The outer wall of the second movable shell 208 is connected to the pipe body 203, and one end of the pipe body 203 is connected to a ring 204 for opening and closing the inner ring gap.
[0071] In this embodiment, the purpose of the above setting is that when it is necessary to adjust the diameter of the output hose, move the second movable shell 208. A distance is generated between the edge of one end of the second movable shell 208 and the inner wall of the outer shell 201. At the same time, the ring 204 moves to close the inner ring gap, so as to guide the material to the outer ring gap.
[0072] As an implementation manner, as Figure 2 - Figure 3 shown, furthermore:
[0073] A sliding frame 206 is connected to the outer wall of the second movable shell 208, and a sliding groove is formed on the outer wall of the outer shell 201;
[0074] The top of the sliding frame 206 is slidably connected to the sliding groove and closes the sliding groove during the sliding process;
[0075] A first movable shell 207 is connected to the outer wall of the sliding frame 206, and the first movable shell 207 is used to close the inner port of the sliding groove of the outer shell 201;
[0076] A lead screw 6 is rotatably connected to the outer wall of the outer shell 201, and the lead screw 6 penetrates through the top of the sliding frame 206 and is threadedly connected.
[0077] In this embodiment, the purpose of the above setting is that by rotating the lead screw 6, since the lead screw 6 penetrates through the top of the sliding frame 206 and is threadedly connected, the sliding frame 206 will slide along the sliding groove on the outer wall of the outer shell 201. 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 states of the inner ring gap and the outer ring gap are opposite, so as to adjust the discharge caliber and shape, and make the plastic hose form different calibers.
[0078] As an implementation manner, as Figure 6As shown, furthermore:
[0079] The conveying assembly 4 includes a support frame 401. 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;
[0080] The output shaft of the second motor 402 penetrates through the top of the support frame 401 and extends to the inner side of the conveyor belt 404. A number of driving blocks 403 are installed on the outer wall of the output shaft of the second motor 402, and a number of strip blocks that cooperate with the driving blocks 403 for driving are installed on the inner wall of the conveyor belt 404.
[0081] In this embodiment, the purpose of the above setting is that when the second motor 402 is started, the driving blocks 403 on its output shaft cooperate with the strip blocks on the inner wall of the conveyor belt 404 for driving. At the same time, through the transmission of the transmission wheel and the transmission belt.
[0082] As an implementation manner, as Figure 6 shown, furthermore:
[0083] A number of mounting blocks 405 are connected to the outer wall of the conveyor belt 404. An arc-shaped block 406 is inserted into the mounting block 405. A number of grooves are evenly arranged on one outer wall of the arc-shaped block 406.
[0084] In this embodiment, the purpose of the above setting is that after the formed plastic hose enters the conveying assembly 4, the arc-shaped block 406 is inserted into the mounting block 405 connected to the conveyor belt 404. The insertion setting is used to replace the arc-shaped block 406 to adapt to hoses of different calibers. The grooves on one outer wall of the arc-shaped block 406 perform thread forming on the outer wall of the hose when the hose is in a plastic state. At the same time, the conveyor belt 404 stably conveys the formed plastic hose.
[0085] As an implementation manner, as Figure 6 shown, furthermore:
[0086] Drive wheels are arranged on the lower surface of the top layer of the support frame 401 and the bottom layer of the support frame 401. One of the drive wheels is connected to the middle shaft of the driving block 403 and is driven by the middle shaft. A transmission belt is connected between the two drive wheels. A roller brush 5 is installed on the other drive wheel. When the arc-shaped block 406 moves, the roller brush 5 rotates to clean the outer wall of the arc-shaped block 406.
[0087] In this embodiment, the purpose of the above setting is that when the central shaft rotates, it drives the two drive wheels and the transmission belt to operate, thereby driving the roller brush 5 to rotate synchronously. When the arc-shaped block 406 moves, the roller brush 5 connected to the drive wheel rotates to clean the outer wall of the arc-shaped block 406.
[0088] During use, the motor 101 is started. The output shaft of the motor 101 drives the screw rod 102 to rotate in the housing 105. 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 towards the discharge port 104. Since the outer wall of the screw rod 102 fits with the inner wall of the housing 105, the plastic particles are compressed during movement and are simultaneously affected by the heat after being heated by the heater 3, and gradually plasticize. Under the continuous transportation of the screw rod 102, the material passes through the discharge port 104. The conical shape and the small holes of the housing 105 help the plasticized plastic to be initially in a strip shape, enabling it to be evenly output to the adjustable die head 2;
[0089] The conical column 205 is used to guide the material entering the outer shell 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, hoses with two different diameters can be discharged;
[0090] By rotating the lead screw 6, since the lead screw 6 passes through the top of the sliding frame 206 and is threadedly connected, the sliding frame 206 will slide along the sliding groove on the outer wall of the outer shell 201. 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 states of the inner ring gap and the outer ring gap are opposite, thereby adjusting the caliber and shape of the discharge, so that the plastic hose is formed into different calibers;
[0091] The second motor 402 is started. The driving block 403 on its output shaft cooperates with the strip on the inner wall of the conveyor belt 404 to drive. At the same time, through the transmission of the transmission wheel and the transmission belt, the formed plastic hose enters the conveying assembly 4. The mounting block 405 connected to the conveyor belt 404 is inserted with an arc-shaped block 406. The insertion setting is used to replace the arc-shaped block 406 to adapt to hoses of different calibers. The groove on the outer wall of one side of the arc-shaped block 406 forms a thread on the outer wall of the hose when the hose is in a plastic state. At the same time, the conveyor belt 404 stably conveys the formed plastic hose;
[0092] When the central shaft rotates, it drives two transmission wheels and the transmission belt to operate, thereby driving the roller brush 5 to rotate synchronously. When the arc-shaped block 406 moves, the roller brush 5 connected to the transmission wheel rotates to clean the outer wall of the arc-shaped block 406.
