DETAILED DESCRIPTION

[0020] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Example

[0022] See also Figure 1-7 In this embodiment, a meter-weight joint control diameter measuring device for extrusion production of cable and wire insulation materials includes: an extruder 1, a feed pipe 101 arranged on one side of the outer end of the extruder 1, a heating frame 102 is arranged on one side of the outer end of the feed pipe 101, a lower hopper 103 is arranged on the top of the feed pipe 101, a detection component arranged on one side of the outer end of the heating frame 102, which is used to measure the diameter of the cable and wire insulation protective sleeve, and a measuring component arranged on the top of the lower hopper 103, which is used to measure the flow rate of material falling into the lower hopper 103.

[0023] Among them, the detection component includes: two calipers 2 arranged on one side of the outer end of the heating frame 102, a support rod 201 connected to the bottom of the caliper 2, and a base 202 connected to the bottom of the support rod 201. When it is necessary to attach the insulating protective cover to the outside of the cable and wire, one end of the cable and wire is passed through one of the calipers 2, and then through the film hole 301 and the other caliper 2, so that the diameters of the wires and cables without and with the film are measured respectively by the two calipers 2, and when the caliper 2 detects that the wires and cables with the film are less than or greater than the set outer diameter, the caliper 2 transmits a signal to the control panel, and the rotation speed of the conveying screw 701 is automatically adjusted through the control panel, thereby adjusting the conveying speed of the solid plastic particles, and resetting the opening duration of the solenoid valve 502 to ensure that the wires and cables with the film meet the set outer diameter.

[0024] The model of the diameter gauge 2 is LMD-D20XYT, and its working principle is that the cable diameter gauge usually adopts laser scanning or CCD imaging technology. When the cable passes through the diameter measuring area, the laser beam emitted by the transmitter or the light captured by the CCD camera will be intercepted by the cable to form a shadow or reflection signal. For the laser scanning method, the laser scanning head scans the cable along the cable axis. According to the change of the receiving end signal after the laser is blocked by the cable, the position information of the cable cross section can be obtained. For the CCD imaging method, the cable will form an image on the CCD chip after passing through the lens. By analyzing the edge features of the image, the cable diameter data is obtained. This scheme does not make any improvements to the circuit or program of the diameter gauge 2. The circuit and signal connection method between the diameter gauge 2 and the control panel also belongs to the public conventional technology, so the circuit and signal connection relationship will not be repeated.

[0025] A die head 3 is installed at one side of the outer end of the heating frame 102, and a film attachment hole 301 is opened at one side of the outer end of the die head 3. When the cables and wires pass through the film attachment hole 301, the melted feed material will adhere to the cables and wires to form an insulating sheath.

[0026] The measuring assembly includes: a top block 4 arranged on the top of the lower hopper 103, a bracket 401 connected to one side of the outer end of the top block 4, a weight loss type weight sensor 402 installed on the top of the bracket 401, and a storage hopper 403 arranged on the top of the weight loss type weight sensor 402. When the device is used, by placing the storage hopper 403 on the top of the weight loss type weight sensor 402, the weight loss type weight sensor 402 can weigh the solid plastic particles entering the lower hopper 103. As the solid plastic particles in the storage hopper 403 fall into the lower hopper 103, the weight loss type weight sensor 402 can monitor the weight of the solid plastic particles in the lower hopper 103 and perform trend measurement, thereby measuring the weight of the solid plastic particles in the lower hopper 103 in real time, and then knowing the traction speed of the solid plastic particles by measuring the rotation speed of the conveying screw 701. Therefore, the thickness of the insulating sheath attached to the cable and wire can be known by dividing the weight of the solid plastic particles in the lower hopper 103 by the traction speed, and by reasonably controlling the weight of the solid plastic particles stored in the lower hopper 103 and reasonably adjusting the rotation speed of the conveying screw 701, the thickness of the insulating sheath attached to the cable and wire can be flexibly changed.

[0027] The model of the loss-in-weight weight sensor 402 is IN-628A, and its working principle is that the total weight of the material is accurately measured and recorded by the weight sensor 402, and the feeding device begins to discharge the material continuously to the downstream process link at a preset speed. As the material continues to decrease, the weight of the material continues to decrease, and the loss-in-weight weight sensor 402 will record the continuous weight of the material and transmit this information to the control system. This solution does not improve the circuit or program of the loss-in-weight weight sensor 402, and the circuit and signal connection method between the loss-in-weight weight sensor 402 and the control panel also belongs to the public conventional technology, so the circuit and signal connection relationship will not be repeated.

[0028] Among them, a feeding frame 6 is arranged at the bottom of the lower hopper 103, the outer side of the feeding frame 6 is connected to the bracket 401, an electric valve 601 is installed inside the lower hopper 103, and both sides of the outer end of the loss-in-weight weight sensor 402 are connected with lifting ears 602, one end of the lifting ear 602 is connected to the inner wall of the lower hopper 103, wherein the feeding frame 6 is installed on the top of the feeding pipe 101, and the feeding frame 6 fixes the top block 4 on the top of the lower hopper 103 through the bracket 401, and the loss-in-weight weight sensor 402 suspends the lower hopper 103 on the top of the top block 4 through the lifting ear 602, so that the loss-in-weight weight sensor 402 can weigh the weight of the solid plastic particles in the lower hopper 103.

[0029] Among them, a motor 7 is installed inside the extruder 1, and a conveying screw 701 is connected to the outer end of the motor 7 through the rotation of the motor shaft. A conveying hole 702 is opened on the outer end of the feed pipe 101. When solid plastic particles fall into the lower hopper 103, they will accumulate on the top of the electric valve 601. Then the electric valve 601 is opened to allow the solid plastic particles in the lower hopper 103 to pass through the electric valve 601 and the feed frame 6 to the conveying hole 702. The motor 7 drives the conveying screw 701 to rotate to convey the solid plastic particles in the conveying hole 702 to the through hole and push them into the heating hole 801.

[0030] Among them, a block 8 is installed at one end of the feed pipe 101, a slot slidably connected to the block 8 is opened on one side of the outer end of the heating frame 102, a material passing hole is opened on one side of the outer end of the block 8, a heating hole 801 is opened on one side of the inner wall of the slot, and multiple heating blocks 802 are installed inside the heating frame 102. When the device is used, the block 8 is slid into the slot to ensure that the solid plastic particles in the material passing hole are transported to the heating hole 801, and the solid plastic particles in the heating hole 801 are melted into a liquid by the heating block 802. As the solid plastic particles continue to enter the heating hole 801, the solid plastic particles melted in the heating hole 801 can be pushed to extrude into the die head 3 to attach the insulating sleeve to the cable and wire.

[0031] The top of the bracket 401 is connected to a feed pipe 5, the bottom of the storage hopper 403 is connected to a plug 501, the top of the storage hopper 403 is provided with a filling port, and the top of the top block 4 is inlaid with a solenoid valve 502, wherein the plug 501 can be inserted into the feed pipe 5, so that the storage hopper 403 is installed on the top of the top block 4, and when the solid plastic particles in the storage hopper 403 need to be discharged into the lower hopper 103, the solenoid valve 502 is opened, so that the solid plastic particles in the storage hopper 403 pass through the plug 501 and the feed pipe 5 and enter the lower hopper 103. 3, and then the weight of the solid plastic particles in the lower hopper 103 is monitored by the loss-in-weight sensor 402. The loss-in-weight sensor 402 can measure the trend according to the solid plastic particles being discharged into the lower hopper 103, and set the discharge value for the loss-in-weight sensor 402 in advance, so that when the loss-in-weight sensor 402 detects that the solid plastic particles have reached the set discharge value, the loss-in-weight sensor 402 controls the solenoid valve 502 to close, wherein the filling port is used to add solid plastic particles into the storage hopper 403.
