Description

Technical Field

[0001] This invention relates to a combination die-cutting machine, and more particularly to a cable insulation extrusion molding apparatus. Background Technology

[0002] Cables are the main connection channel for energy transmission at present. Most cables are installed in the air and are easily damaged by wind and sun exposure during long-term use. Therefore, a protective shell is added to the outer surface of the cable.

[0003] In the cable production process, to avoid the formation of joints, a direct adhesive method is used to wrap the cable to enhance its protective properties. However, the previous wrapping method is cumbersome and uneven, which can easily lead to a decrease in the protective effect of the outer shell. Therefore, it is necessary to develop a cable insulation extrusion molding device. Summary of the Invention

[0004] To address the technical deficiencies in the background technology, this invention proposes a cable insulation extrusion molding apparatus, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows: The purpose of this invention is to provide a cable insulation extrusion molding apparatus, which aims to solve the technical problems in the prior art, such as the need for frequent placement and removal of cable sleeves, which wastes too much processing time, and the cable sleeves being prone to getting stuck in the mold due to expansion after molding, causing trouble in removal and further wasting processing time. In addition, the removed cable sleeves need to be collected before they can enter the next processing stage.

[0005] To achieve the above objectives, embodiments of the present invention provide a cable insulator extrusion molding apparatus. Optionally, a cable insulation extrusion molding apparatus includes: a pad, a flipping mechanism, an internal high-voltage mechanism, a blocking mechanism, a storage chamber, a pressing mechanism, and a base.

A base is located adjacent to the hollow shaft of the pad. A lower template is located above the flipping plate. Two flipping mechanisms are provided and fixed to the left and right sides of the base. Each flipping mechanism includes: a housing, a bushing, a shaft rod, and a drive motor. The shaft rod extends across the two housings, and bushings are fitted to both ends of the shaft rod. The lower part of the bushing is meshed with a gear of the drive motor. The flipping mechanism rotates the shaft rod, and the shaft... The lever drives the flipping plate to flip upwards; the internal high-pressure mechanism includes: a propulsion machine, a frame, a pressurizing pump, and two clamping plates. The propulsion machine is located above the frame and is fixed to the front of the base through the frame. The pressurizing pump is clamped between the two clamping plates. The blocking mechanism is located behind the base and is fixed above the pad. The storage compartment is located behind the blocking mechanism. An opening is provided on the side of the storage compartment adjacent to the blocking mechanism, and a downward-hanging top rod is provided above the opening. A return spring is used to connect the spring sheet below the top rod. The pressing mechanism has at least four uprights. The four uprights are located around the base. The pressing mechanism is fixed to the top of the base through the four uprights. An upper template is provided below the pressing mechanism and is set relative to the lower template.

[0006] The section of the pad that is connected to the flip plate has a chamfer; the rear of the flip plate is limited by the pad to maintain a vertical state.

[0007] The two ends of the shaft of the flipping mechanism extend to the outside of the two housings respectively. The bottom of the two housings is provided with an opening, and the drive motor inside the housing is electrically connected to an external power supply device.

[0008] The internal high-pressure mechanism's propulsion mechanism is connected to a push tube, which moves back and forth via the propulsion mechanism. A glue injection tube is located within the push tube. The front end of the glue injection tube is axially symmetrical to the blocking mechanism, and the rear end of the glue injection tube is connected to a pressure pump. The lower end of the pressure pump is connected to an external glue source, and a tube extends to the glue source. The frame has at least two strip grooves on one side adjacent to the two clamping plates. One of the two clamping plates is fixed to the frame, and the other clamping plate has at least two protruding strips. The other clamping plate uses its two protruding strips to insert into the two strip grooves, and moves back and forth along the two strip grooves via the two protruding strips. The ends of the two clamping plates away from the frame have screw holes, and screws mesh within the screw holes of the two clamping plates.

[0009] The blocking mechanism is a propulsion machine, and a pushing tube is provided inside the blocking mechanism. The pushing tube in the blocking mechanism is solid. A second pad is provided at the front and bottom of the storage compartment. The storage compartment is fixed to the second pad by a connecting plate. The second pad is fixed to the front of the base. An outlet is provided at the rear and bottom of the storage compartment.

[0010] The pressing mechanism includes: a support base, a pressing cylinder, a second pad, four uprights, and an upper template; the tops of the four uprights are supported and connected to the second pad, the second pad has a support base above it, and the pressing cylinder is connected above the support base; the pressing cylinder has a pressing rod inside it, which passes through the second pad, and the pressing rod of the pressing mechanism moves up and down, with the lower end of the pressing rod connected to the upper template.

[0011] The cable insulation extrusion molding apparatus provided in this invention has at least one of the following technical effects: In this invention, after the cable sleeve is processed, it is flipped upward by a flipping plate, which is then placed vertically. The lower template on the flipping plate is also set vertically. Due to the high-pressure processing inside, the cable sleeve will be blocked in the groove of the lower template. The vertically placed flipping plate presses the cable sleeve into the storage compartment. The spring piece above the storage compartment is pressed by the cable sleeve and rotates backward. When the spring piece reaches the tube, it is not pressed by the edge of the cable sleeve and resets. When the flipping plate resets, the cable sleeve is pulled by the spring piece inserted into the tube and pulled backward by the flipping plate, thereby causing the cable sleeve to fall out of the lower template. After falling out, the cable sleeve falls downward without any obstruction and falls out of the storage compartment.

[0012] The pad of the present invention is used to support a flat flip plate, and also provides support for the pressing mechanism when the flip plate is pressed down during processing.

[0013] The flipping mechanism of the present invention is used to flip the flipping plate upward, and the present invention uses a shaft to drive the flipping plate to flip.

[0014] The internal high-pressure mechanism of this invention is used to push the pipe for injecting glue to the pipe opening. The structure of the blocking mechanism is also to push the solid tube for sealing the pipe to the other pipe opening, so that the two ends of the pipe are sealed. After the glue is injected from the internal high-pressure mechanism, it is pressurized to prevent the injected glue from leaking. The glue injection mechanism of the internal high-pressure mechanism of this invention draws the glue from the outside through a pressure pump and injects it into the cable sheath under pressure.

[0015] The pressing mechanism of this invention drives the upper template to press down on the upper template, so that a cavity for forming a cable sleeve is formed between the two templates. Attached Figure Description

Detailed Implementation

[0017] The embodiments of the present invention will be described below with reference to the accompanying drawings and related examples. The embodiments of the present invention are not limited to the following examples, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0018] like Figures 1-9As shown, a cable insulation extrusion molding apparatus is provided, comprising: a pad 1, a flipping mechanism 2, an internal high-voltage mechanism 3, a blocking mechanism 4, a storage chamber 5, a pressing mechanism 6, and a base 7. The pad 1 is located above the base 7, and a flipping plate 11 is provided above the pad 1. A hollow shaft is provided behind the flipping plate 11, and a shaft rod 23 passes through the hollow shaft of the flipping plate 11. A pad seat 71 is provided adjacent to the hollow shaft of the pad 1. A lower template 111 is provided above the flipping plate 11. Two flipping mechanisms 2 are provided and are respectively fixed on the left and right sides of the pad seat 71. Each flipping mechanism 2 includes: a housing 21, a bushing 22, a shaft rod 23, and a drive motor 24. The shaft rod 23 passes through the two housings 21, and both ends of the shaft rod 23 are fitted with bushings 22. The lower part of the bushings 22 is meshed with a gear provided on the drive motor 24. The flipping mechanism 2 rotates the shaft rod 23, and the shaft rod... 23 drives the flip plate 11 to flip upward; the internal high pressure mechanism 3 includes: a propeller 31, a frame 32, a pressurizing pump 33 and two clamping plates 34. The propeller 31 is located above the frame 32 and is fixed to the front of the base 7 through the frame 32. The pressurizing pump 33 is clamped between the two clamping plates 34; the blocking mechanism 4 is located behind the base 7 and is fixed above the pad 71; the storage compartment 5 is located behind the blocking mechanism 4. The storage compartment 5 has an opening on the side adjacent to the blocking mechanism 4, and a downward-hanging top rod 511 is provided above the opening. The top rod 511 is connected to the spring piece 512 by a return spring below it. The pressing mechanism 6 has at least four uprights 631. The four uprights 631 are located around the base 7. The pressing mechanism 6 is fixed to the top of the base 7 through the four uprights 631. The pressing mechanism 6 has an upper template 64 below it and is relative to the lower template 111.

[0019] In this invention, after the cable sleeve is processed, it is flipped upward by the flipping plate 11 and placed vertically. The lower template 111 on the flipping plate 11 is also set vertically. Due to the high-pressure processing inside, the cable sleeve will be blocked in the groove of the lower template 111. The vertically placed flipping plate 11 presses the cable sleeve into the storage compartment 5. The spring piece 512 above the storage compartment 5 is pressed by the cable sleeve and rotates backward. When the spring piece 512 reaches the tube, it is not pressed by the edge of the cable sleeve and resets. When the flipping plate 11 resets, the cable sleeve is pulled by the spring piece 512 inserted into the tube and pulled backward by the flipping plate 11, so that the cable sleeve falls out of the lower template 111. After falling out, the cable sleeve falls down without obstruction and falls out along the storage compartment 5.

[0020] In the invention, during the cable sheath extrusion process, the cable core is inserted into the extrusion end, and the cable core is pushed into the center of the cable sheath by a guiding device (such as a motor), thereby achieving a snug fit and reducing the seams formed by splicing, further preventing detachment.

[0021] The pad 1 of the present invention is used to support the flat flip plate 11, and also provides support for the pressing mechanism 6 when the flip plate 11 is pressed down for processing.

[0022] The flipping mechanism 2 of the present invention is used to flip the flipping plate 11 upward, and the present invention uses a shaft to drive the flipping plate 11 to flip.

[0023] The internal high-pressure mechanism 3 of this invention is used to push the pipe for injecting glue to the pipe opening. The structure of the blocking mechanism 4 is also to push the solid tube for sealing the pipe to the other pipe opening, so that the openings at both ends of the pipe can be sealed. After the glue is injected from the internal high-pressure mechanism 3, it is pressurized to prevent the injected glue from leaking. The glue injection mechanism of the internal high-pressure mechanism 3 of this invention draws the glue from the outside through the pressure pump 33 and injects it into the cable sheath under pressure.

[0024] The pressing mechanism 6 of the present invention drives the upper template 64 to press down on the upper template 111, so that a cavity for forming a cable sleeve is formed between the two templates.

[0025] With the above structure, it should be further noted that the vertical height of the flip plate 11 of the present invention is not higher than the height of the upper template 64 after it is lifted.

[0026] After the flip plate 11 is vertical, the diameter of the cable sleeve clamped by the lower template 111 of the flip plate 11 is sufficient to press the spring piece 512, and when the flip plate 11 is vertically stationary, the spring piece 512 is not subjected to pressure, thus resetting vertically.

[0027] The shaft 23 of the present invention is a circle with a toothed cross-section. This setting allows the edge to engage with the hollow shaft, preventing the shaft 23 from slipping easily with the flip plate 11 when it rotates.

[0028] The present invention uses the pressing mechanism 6 to press the upper template 64 onto the lower template 111, clamping and fixing the cable sleeve placed on the lower template 111. Then, the blocking mechanism 4 pushes the pushing tube 331 to the opening of the cable sleeve. Finally, the inner high-pressure mechanism 3 pushes the pushing tube 331 to the other opening of the cable sleeve for glue injection and pressure to form the cable sleeve. After processing, the inner high-pressure mechanism 3 and the blocking mechanism 4 are reset, and the pressing mechanism 6 also resets the upper template 64. At this time, the flipping mechanism 2 flips the flipping plate 11 upward to the spring piece 512, separating the cable sleeve of the lower template 111 and discharging it in a concentrated manner.

[0029] The section connecting the pad 1 to the flip plate 11 has a chamfer; the rear of the flip plate 11 is limited by the pad 71 to maintain a vertical state.

[0030] With the above structure, it should be further explained that the chamfer set on the section where the pad 1 is connected to the flip plate 11 can prevent the flip plate 11 from colliding with the pad 1 after it is reset, and also provides a space to accommodate the protruding hollow shaft.

[0031] The two ends of the shaft 23 of the flipping mechanism 2 extend to the outside of the two housings 21 respectively. The bottom of the two housings 21 is provided with an opening. The drive motor 24 inside the housing 21 is electrically connected to an external power supply device.

[0032] With the above structure, it should be further explained that the two drive motors 24 of the present invention rotate synchronously to provide greater power for the flipping plate 11 to flip.

[0033] The propulsion mechanism 31 of the internal high-pressure mechanism 3 is connected to the push tube 331, and the push tube 331 moves back and forth through the propulsion mechanism 31. The push tube 331 is provided with a glue injection tube 332. The front end of the glue injection tube 332 is axially symmetrical to the blocking mechanism 4, and the rear end of the glue injection tube 332 is connected to the pressure pump 33 by a tube. The lower end of the pressure pump 33 is connected to the external glue source, and a tube extends to the glue source. The frame 32 and the side adjacent to the two clamping plates 34 are provided with at least two strip grooves. One of the two clamping plates 34 is fixed to the frame 32, and the other clamping plate 32 is provided with at least two protrusions. The other clamping plate 32 is inserted into the two strip grooves by the two protrusions respectively, and the other clamping plate 32 moves back and forth along the two strip grooves by the two protrusions. The ends of the two clamping plates 34 away from the frame 32 are provided with screw holes, and screws 341 are engaged in the screw holes of the two clamping plates 34.

[0034] With the above structure, it should be further explained that the pusher 31 of the present invention uses a hydraulic press to push the pusher tube 331, and the pusher tube 331 is pushed to the cable sleeve and continues to be pushed, so that the pusher tube 331 and the cable sleeve are kept in close contact to avoid liquid leakage and insufficient pressure.

[0035] The blocking mechanism 4 is a propulsion machine 31. The blocking mechanism 4 is equipped with a push tube 331. The push tube 331 in the blocking mechanism 4 is solid. The front and bottom of the storage compartment 5 is equipped with a pad 72. The storage compartment 5 is fixed to the pad 72 by a connecting plate. The pad 72 is fixed to the front of the base 7. The rear and bottom of the storage compartment 5 is equipped with an outlet.

[0036] With the above structure, it should be further explained that the push tube 331 of the blocking mechanism 4 is solid, which can increase the blocking area; the inclined surface on the upper part of the blocking mechanism 4 can guide the falling cable sleeve to roll into the storage bin 5, and a collection box can be placed at the lower outlet of the storage bin 5 to collect the processed cable sleeves for easy subsequent centralized handling.

[0037] The actuator 31 of the present invention is electrically connected to an external power source. The actuator 31 is started by the external power source and uses hydraulic pressure to drive the actuator tube 331.

[0038] The pressing mechanism 6 includes: a support base 61, a pressing cylinder 62, a second pad 63, four uprights 631, and an upper template 64; the top of the four uprights 631 is supported and connected to the second pad 63, the support base 61 is provided above the second pad 63, and the pressing cylinder 62 is connected above the support base 61; the pressing cylinder 62 is provided with a pressing rod inside and passes through the second pad 63, the pressing rod of the pressing mechanism 6 moves up and down, and the lower end of the pressing rod of the pressing mechanism 6 is connected to the upper template 64.

[0039] With the above structure, it should be further explained that the height of the second pad 63 of the present invention is higher than that of the flip plate 11 in the vertical state, and the pressing mechanism 6 is supported by four uprights 631, which can increase the supporting force generated by pressing.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
