[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Example:

[0052] The following is combined with Figure 1-9 The present invention is described in further detail.

[0053] See also Figure 1-9 The present invention provides a technical solution: a device and method for processing internal threads of a cable protection tube, comprising:

[0054] A support table 1, with first support columns 2 disposed on both sides of the support table 1, a feeding roller 3 installed on the top of the first support column 2, a first feeding platform 4 installed on the surface of the feeding roller 3, a second feeding platform 5 disposed on one side of the first feeding platform 4, a convex soft block installed on the surface of the second feeding platform 5 for supporting the lifting of the cable protection tube, a second support column 15 installed between the second feeding platform 5 and the first feeding platform 4, the second feeding platform 5 is connected to the first feeding platform 4 through the second support column 15, a supporting telescopic rod 6 is installed at one end of the second feeding platform 5, and the second feeding platform 5 is used to adjust the feeding distance of the first feeding platform 4;

[0055] The guide plate 7 is installed on the side of the feeding roller 3 away from the first feeding platform 4. The top of the guide plate 7 abuts against the surface of the feeding roller 3. An auxiliary isolation plate 8 is installed on the surface of the guide plate 7. The guide plate 7 is an embedded design and is used to adjust the processing direction of the cable protection tube.

[0056] A first power supply box 13, a cutting head 14 is installed on one side of the first power supply box 13 close to the guide plate 7, a processing table 10 is provided on one side of the first power supply box 13, the processing table 10 is installed on the surface of the support table 1, a height adjustment plate 11 is installed on the surface of the support table 1, a clamping member 12 is movably connected inside the height adjustment plate 11, a camera 9 is installed on one side of the guide plate 7 close to the processing table 10, and the camera 9 is used to assist the feed adjustment of the guide plate 7;

[0057] In this embodiment: In the above embodiment, the general framework of the device designed this time is provided, and what needs to be further explained here is the main working principle of the device designed, which is as follows:

[0058] Among them, the device supports or assists in supporting all mechanisms with a support table 1. It can be seen that the cable protection tube / material is adjusted, and is transported through the first feeding platform 4, the second feeding platform 5, and the guide plate 7. Finally, it is clamped by the clamping member 12 on the surface of the processing table 10, and the material is processed by the cutting head 14. In this process, it should be noted that the second feeding platform 5 and the first feeding platform 4 are connected by a second support column 15, which means that the second feeding platform 5 is a replaceable conveyor belt, and the end of the second feeding platform 5 away from the first feeding platform 4 needs to be inserted into the material, and the material is gradually taken out from the inside of the material by the rotation of the second feeding platform 5, so that the material can be spread on the surface of the second feeding platform 5, and then enter the surface of the first feeding platform 4, and then enter the surface of the guide plate 7 under the transportation of the first feeding platform 4. After the materials are gathered, in the actual use process, it can be seen that the materials are transported in disorder on the surfaces of the first feeding platform 4 and the second feeding platform 5. Therefore, the function of the guide plate 7 is to change the first feeding platform 4 and the second feeding platform 5 from being unnecessary to being transported in order, that is, the materials enter the surface of the processing table 10 longitudinally through the guide plate 7 and the auxiliary isolation plate 8, and are in a state to be processed, thereby enhancing the feeding effect of the device, and when the materials enter the surface of the processing table 10, the inside of the processing table 10 will be fixed by the clamping member 12, thereby ensuring that when the cutting head 14 processes the materials, from feeding to loading and even processing, no manual intervention is required, which greatly enhances the automation level of the device, thereby liberating the labor cost, optimizing the digitalization and intelligentization of the product, and improving the working efficiency of the device;

[0059] It should also be explained that, during the actual use of the device, the supporting telescopic rod 6 is a conventional telescopic structure, which provides support for the use of the second feeding platform 5, and the second supporting column 15 serves as the connecting part between the second feeding platform 5 and the first feeding platform 4. The second feeding platform 5 can be adjusted by the length of the supporting telescopic rod 6, and the connection angle between the second feeding platform 5 and the first feeding platform 4 can be adjusted by relying on the second supporting column 15, thereby effectively ensuring the feeding effect of the second feeding platform 5. In such a setting, when the material is piled, the second feeding platform 5 can be directly inserted into the bottom of the material. When the material is dropped into the feeder, the supporting telescopic rod 6 can be placed directly on the ground, and the supporting angle of the second feeding platform 5 can be adjusted to avoid the problem of the material popping out when it falls to the surface of the second feeding platform 5.

[0060] like Figure 1-9As shown, a supporting side panel 101 is installed on the surface of the supporting table top 1, and the installation position of the supporting side panel 101 needs to overlap both sides of the first feeding platform 4 and the second feeding platform 5. The supporting side panel 101 is used to support the materials on the surface of the first feeding platform 4 and the second feeding platform 5 to prevent the materials from falling.

[0061] In this embodiment: It should be noted that during the use of the device, it is necessary to ensure that the supporting side plates 101 can be installed on the surface of the supporting table 1 to support the first feeding platform 4 and the second feeding platform 5. Because in the actual use process, even if the first feeding platform 4 and the second feeding platform 5 can transmit materials, material accumulation will inevitably occur under the retreat of the guide plate 7. Even if the rotation speed of the first feeding platform 4 and the second feeding platform 5 is controlled, it is impossible to achieve a perfect situation under the speed control. Materials will inevitably accumulate on the surface of the guide plate 7 and then retreat to the connection between the first feeding platform 4 and the guide plate 7. Then the role of the supporting side plates 101 is to ensure that the materials on the surface of the first feeding platform 4 will not accumulate and then scatter. Therefore, the supporting side plates 101 are the prerequisite for the normal and safe use of the first feeding platform 4. With this setting, the safety of loading during the use of the device is guaranteed.

[0062] like Figure 1-9 As shown, a material guide surface 18 is provided on the surface of the guide plate 7, and elastic limit plates 21 are installed on both sides of the material guide surface 18. The elastic limit plates 21 are elastic structures installed on the surface of the guide plate 7. A friction clamping wheel 19 is also installed on the surface of the guide plate 7. A third power supply box 17 is installed on the top of the guide plate 7, and a second power supply box 16 is installed on the bottom of the guide plate 7.

[0063] A rotating guide roller 20 is clamped inside the material guide table 18. The rotating guide roller 20 is designed and installed in an axisymmetric manner. The rotating guide roller 20 is used to guide the material on the surface of the guide plate 7.

[0064] A height adjustment shaft seat is provided at the connection between the friction clamping wheel 19 and the guide plate 7. The height adjustment shaft seat is electrically controlled and used to adjust the distance between the friction clamping wheel 19 and the guide plate 7.

[0065] The two friction clamping wheels 19 close to the second power supply box 16 are installed in a close-fitting manner, and the two friction clamping wheels 19 need to cover the discharge area of ​​the material guide table 18;

[0066] In this embodiment, through such a setting, during the use of the device, it can be found that the third power supply box 17 and the second power supply box 16 provide power for the rotating guide roller 20 to ensure that the rotating guide roller 20 can retract the material by rotating the body and cooperating with the rotation of the friction clamping wheel 19 during the use. During the material retraction process, the disordered material entering the guide plate 7 will gradually become longitudinally arranged through the guidance of the rotating guide roller 20 and the friction clamping wheel 19, and then be discharged from the inside of the guide plate 7, and then enter the table to be processed. It should be noted that various unexpected situations may occur during the use of the device, such as:

[0067] The material accumulates on the surface of the material guide table 18. Although the direction of the rotating guide roller 20 is adjusted, the friction clamping wheel 19 can only be pressed against the two sides of the material guide table 18. Therefore, during the actual use of the device, the material can be accumulated along the central axis of the material guide table 18, and then, the material is likely to slide to the side close to the discharge port of the guide plate 7, causing a large piece of material to fall. This situation mostly occurs when the feeding rate of the first feeding platform 4 and the second feeding platform 5 is not well controlled. Therefore, we install a dislocation baffle 201 so that the dislocation baffle 201 can cover the guide plate 7 to ensure that the material does not fall and affect the processing of the cutting head 14. The accumulated material will accumulate in the empty space between the guide plate 7 and the auxiliary isolation plate 8 to avoid problems affecting the normal use of the device.

[0068] Secondly, in the actual use process, it is possible that two or more materials are accumulated at the discharge port of the guide plate 7. At this time, the discharge port of the guide plate 7 is completely stuck, and the material cannot be discharged, resulting in the inability to operate the device. Therefore, we can also solve this problem by setting two friction clamping wheels 19 near the discharge port of the guide plate 7. The specific solution is shown in the following embodiment.

[0069] like Figure 1-9 As shown, a dislocation baffle 201 is clamped on the surface of the guide plate 7;

[0070] The dislocation baffle 201 is used to limit the dislocation materials in the transmission of the guide plate 7;

[0071] The surface of the dislocation baffle 201 is movably mounted with a telescopic plate 203, which can be electrically controlled, and the height of the telescopic plate 203 matches the height of the two friction clamping wheels 19 close to the second power supply box 16;

[0072] An auxiliary material removal wheel 204 is installed at the bottom of the telescopic plate surface 203, and the auxiliary material removal wheel 204 is used to assist in removing the material that is dislocated during the transmission of the guide plate 7;

[0073] A discharging opening 202 is provided at the bottom of the dislocation baffle 201, and the opening specification of the discharging opening 202 matches the discharging specification of the guide plate 7;

[0074] In this embodiment, a dislocation baffle 201 component is installed to solve the problem of material dislocation from the central axis of the guide plate 7 during the transmission process. It can be seen that when the discharge opening 202 is opened, the discharge opening 202 is located directly above the two friction clamping wheels 19 close to the second power supply box 16. The friction clamping wheels 19 and the telescopic plate surface 203 need a certain distance to avoid the bottom of the friction clamping wheels 19 and the telescopic plate surface 203 from fitting together, but at the same time they cannot fit completely together to avoid the rotation of the friction clamping wheels 19 being affected. After the material is dislocated, the dislocation baffle 201 has two installation methods: carrying the top plate so that the guide plate 7 is installed in a closed space; removing the top plate so that the guide plate 7 is installed in an open space;

[0075] The material begins to dislocate along the central axis of the guide table 18 inside the guide plate 7. During the dislocation process, the falling top plate hits the top of the friction clamping wheel 19. If there is less material, it will hit the surface of the auxiliary material-pickling wheel 204. If there is more material, it will hit the top of the auxiliary material-pickling wheel 204. The auxiliary material-pickling wheel 204 itself does not have the function of active rotation. If a rotation function is added here, the manufacturing cost of the telescopic plate 203 is too high. Then, when the material is against the surface of the auxiliary material-pickling wheel 204, the bottom of the material must overlap with the friction clamping wheel 19. During the rotation of the friction clamping wheel 19, the material will contact the friction clamping wheel 19. The material may slide down inside the material guide table 18, or fall on both sides of the guide plate 7. If too much material is accumulated, the material on the top will be moved out with the rotation of the auxiliary material transfer wheel 204. Because too much material falls under the influence of the rotation of the friction clamping wheel 19, it will inevitably affect the rotation of the auxiliary material transfer wheel 204 during the falling or even moving process. In addition, the connecting shaft between the auxiliary material transfer wheel 204 and the telescopic plate 203 is made of soft material. Under the influence of gravity, as long as the auxiliary material transfer wheel 204 contacts the friction clamping wheel 19, it will also rotate with the friction clamping wheel 19, thereby accumulating the dislocated and fallen materials on both sides of the guide plate 7.

[0076] like Figure 1-9 As shown, the bottom of the friction clamping wheel 19 is a curved surface, and the top and bottom of the friction clamping wheel 19 are both provided with friction convex rollers 22 for enhancing the friction between the friction clamping wheel 19 and the cable protection tube;

[0077] In this embodiment, in order to solve the blocking problem mentioned in the above embodiment, we designed a friction clamping wheel 19 and its related structural parts. It can be found that when the friction clamping wheel 19 is rotating, the gap between the two friction clamping wheels 19 will not allow the second material to pass through the bottom of the friction clamping wheel 19 and enter the outlet of the material guide table 18. Even if this happens, the two material guide tables 18 cannot pass through here side by side. Figure 6 In the embodiment, since the bottom of the friction clamping wheel 19 is a curved surface design, in the "discharging space" constructed by the two friction clamping wheels 19 at the outlet of the guide plate 7, once two materials enter the "discharging space" side by side from below the friction clamping wheels 19, the materials will inevitably contact the bottom of the friction clamping wheel 19, thereby being squeezed by the friction convex roller 22 and the friction clamping wheel 19, and then, under the rotation of the friction clamping wheel 19, the materials will retreat to the waiting feeding area, that is, the surface of the material guide table 18, and slide down again under the action of gravity. Moreover, since the top of the friction clamping wheel 19 is also provided with a friction convex roller 22, once the materials are dislocated at the central axis of the material guide table 18, they can be quickly thrown back to the surface of the material guide table 18 through the contact between the materials and the top of the friction clamping wheel 19, or fall on both sides of the material guide table 18, thereby effectively avoiding the problem that the materials are easily accumulated at the outlet of the friction clamping wheel 19, thereby affecting the feeding effect of the friction clamping wheel 19.

[0078] The rotating guide roller 20 is arranged to rotate in the same direction, and a connecting shaft seat 23 is movably connected to the bottom of the rotating guide roller 20. A supporting positioning plate 25 is arranged inside the material guide table 18. The supporting positioning plate 25 is used to support the installation and fixation of the connecting shaft seat 23. A material-diverting wave beating plate 24 is arranged on the surface of the rotating guide roller 20.

[0079] In this embodiment, the rotating guide roller 20 and the material-diverting wave beating plate 24 are initially set to rotate in the same direction, and then the direction of the rotating guide roller 20 can be adjusted by controlling the starter of the rotating guide roller 20. The specific rotation direction can be determined according to the situation. During the rotation process, the material-diverting wave beating plate 24 is fan-shaped, but the side close to the supporting positioning plate 25 is straight-edged, which is used to drive the material-diverting wave beating plate 24 to dig the material on the surface of the material guide table 18 through the rotation of the rotating guide roller 20 under the guidance of gravity, so as to ensure that the material will not be separated from the surface of the material guide table 18, so as to ensure that the material is unobstructed.

[0080] A processing method for a cable protection tube internal thread processing device according to claims 1-6, comprising:

[0081] The cable protection tubes to be processed are piled up on the surface of the second feeding platform 5, and one end of the second feeding platform 5 is inserted into the bottom of the material pile. The feeding angle of the second feeding platform 5 is adjusted by the supporting telescopic rod 6 so that it is overlapped to the first feeding platform 4 through the second supporting column 15;

[0082] The rotation speed of the feeding roller 3 is controlled, and the second feeding platform 5 and the first feeding platform 4 are operated in coordination to drive the cable protection tube to be processed from the feeding area to the surface of the guide plate 7;

[0083] After the cable protection tube to be processed enters the guide plate 7, it gradually changes from a state without feeding to a state of longitudinal arrangement feeding under the guidance of the rotating guide roller 20, and is stably transported toward the outlet of the guide table 18 under the clamping of the friction clamping wheel 19 and the action of the friction convex roller 22;

[0084] If the cable protection tube to be processed is offset or dislocated during the guiding process, the dislocation baffle 201 will limit it on the surface of the guide plate 7, and the dislocated cable protection tube to be processed will be guided out or retracted to the guide channel guide table 18 under the action of the auxiliary material wheel 204 driven by the telescopic plate 203;

[0085] The position of the friction clamping wheel 19 is dynamically adjusted to adapt to cable protection tubes of different diameters;

[0086] The cable protection tube to be processed is guided into the processing table 10 and fixed in place by the clamping member 12, and the inner wall of the cable protection tube to be processed is threaded under the drive of the cutting head 14;

[0087] The method for controlling the speed of the feeding roller 3 is specifically as follows:
