[0002] Injection molding machines are molding equipment that use plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. They are widely used in plastic pipe processing. The current injection molding machines can perform injection molding on various types of pipes. With the development of the times, the requirements for injection molding precision are getting higher and higher. However, the temperature of the newly injection molded pipe is high, and its own shaping performance is poor, and it cannot maintain the shaping state, which leads to the problem of shaping easily in the process of shaping through the mold, making it difficult for the precision of the pipe to meet the use requirements.

A plastic injection molding machine for optical cable production in the invention can realize automatic material change of the injection molding machine, so that it can quickly switch different raw materials during the production process to meet the production needs of different types of optical cables, or quickly replace the raw materials when raw material quality problems are detected, thereby avoiding production interruption or product quality damage, ensuring high efficiency and high quality of optical cable production, and improving the automation level and flexibility of the production line.

[0026] Further, the analysis module compares the inner diameter length of the pipe orifice of the wire sleeve detected by the detection module with the standard value of the inner diameter length of the pipe orifice to obtain a pipe orifice inner diameter length deviation parameter, and compares the pipe orifice inner diameter length deviation parameter with the pipe orifice inner diameter length deviation value to determine whether the pipe orifice inner diameter length of the wire sleeve is qualified;

[0027] If the pipe orifice inner diameter length deviation parameter is less than the pipe orifice inner diameter length deviation value, the analysis module determines that the pipe orifice inner diameter length of the wire sleeve is qualified;

[0028] If the nozzle inner diameter length deviation parameter is not less than the nozzle inner diameter length deviation value, the analysis module determines that the nozzle inner diameter length of the wire sleeve is unqualified and adjusts the injection unit according to the nozzle inner diameter length deviation parameter;

[0037] If the comprehensive deviation parameter is not less than the comprehensive deviation value, the analysis module determines that the wire sleeve is unqualified and adjusts the injection unit according to the comprehensive deviation parameter;

[0038] Among them, the comprehensive deviation value is positively correlated with the maximum curvature of the wire sleeve.

[0039] Furthermore, the analysis module is externally connected to an audio-visual display screen for receiving the determination information of the analysis module and for the user end to control the injection molding module through the audio-visual display screen;

[0040] The determination information includes the determination result of each of the finished product parameters by the analysis module.

[0063] A preheating unit, which is connected to the feeding unit and is used to preheat the raw materials;

[0064] The injection unit is connected to the preheating unit and is used for injection molding the preheated raw materials.

[0065] Specifically, a plurality of cameras are provided in the detection module and a scale is provided corresponding to each camera. When measuring the parameters of the finished product, the camera takes a photo of the corresponding scale and the corresponding wire sleeve. The parameters of each finished product can be obtained by referring to the scale of the scale in the wire sleeve photo.

[0066] Preferably, the positions of the camera and the scale can be adjusted according to the required parameters.

[0067] Please cooperate Figure 5 See also Figure 4 As shown, they are respectively a schematic diagram of the detection module of an embodiment of the present invention axially measuring the parameters of a finished product and a schematic diagram of the detection module of an embodiment of the present invention measuring the parameters of a finished product;

[0068] In one embodiment, the number of corrugations of the wire sleeve 1 is measured to be 15, the peak spacing is measured to be 4.3 mm with reference to the first scale 2, the inner diameter of the tube mouth is measured to be 5.5 mm with reference to the second scale 3, and the tube wall thickness is 1 mm.

[0069] Specifically, the detection module of the present invention detects the factors affecting the quality of the wire sleeve more comprehensively, and the analysis module determines in real time through the detection results how to make corresponding adjustments to the injection molding module. While ensuring the quality of the wire sleeve, the accuracy of the quality judgment of the wire sleeve and the injection molding efficiency of the wire sleeve are improved.

[0070] Specifically, the analysis module compares the number of corrugations of the wire sleeve detected by the detection module with the standard value of the number of corrugations to obtain a corrugation number deviation parameter, and compares the corrugation number deviation parameter with the corrugation number deviation value to determine whether the number of corrugations of the wire sleeve is qualified;

[0071] If the corrugation quantity deviation parameter is less than the corrugation quantity deviation value, the analysis module determines that the number of corrugations of the wire sleeve is qualified and further determines the remaining finished product parameters;

[0072] If the corrugation quantity deviation parameter is not less than the corrugation quantity deviation value, the analysis module determines that the corrugation quantity of the wire sleeve is unqualified and adjusts the injection unit according to the corrugation quantity deviation parameter.

[0073] Example 1: Please refer to Figure 3 As shown, it is a flow chart of the analysis module according to the embodiment of the present invention comparing each deviation parameter with the corresponding deviation value to determine whether the wire sleeve is qualified;

[0074] In this embodiment, the standard value of the number of corrugations is 10, and the deviation value of the number of corrugations is 1. If the number of corrugations of the wire sleeve is 10, the obtained corrugation number deviation parameter is 0, which is less than the corrugation number deviation value 1. The analysis module determines that the number of corrugations of the wire sleeve is qualified, and further determines the remaining finished product parameters;

[0075] If the number of corrugations of the wire sleeve is 12, and the corrugation number deviation parameter is 2, which is greater than the corrugation number deviation value 1, the analysis module determines that the number of corrugations of the wire sleeve is unqualified and adjusts the injection unit according to the corrugation number deviation parameter.

[0076] It is understandable that, for those skilled in the art, the number of corrugations of the wire sleeve can be adjusted by adjusting the operating parameters of the injection molding machine and the shape of the mold, which will not be elaborated here.

[0077] Among them, the standard value of the number of corrugations is positively correlated with the maximum curvature of the wire sleeve; the deviation value of the number of corrugations is positively correlated with the maximum curvature of the wire sleeve.

[0078] It can be understood that the maximum curvature of the wire sleeve is the maximum angle at which the wire sleeve can be bent without a change in cross-sectional area during the bending process.

[0079] In one embodiment, when the maximum curvature of the wire sleeve is 30 degrees, the standard value of the number of corrugations is 10, and the deviation value of the number of corrugations is 1;

[0080] When the maximum curvature of the wire sleeve is 45 degrees, the standard value of the number of corrugations is 15, and the deviation value of the number of corrugations is 2;

[0081] When the maximum curvature of the wire sleeve is 60 degrees, the standard value of the number of corrugations is 20 and the deviation value of the number of corrugations is 3.

[0082] Specifically, the analysis module compares the peak spacing of the wire sleeve detected by the detection module with the peak spacing standard value to obtain a peak spacing deviation parameter, and compares the peak spacing deviation parameter with the peak spacing deviation value to determine whether the peak spacing of the wire sleeve is qualified;

[0083] If the peak spacing deviation parameter is less than the peak spacing deviation value, the analysis module determines that the peak spacing of the wire sleeve is qualified and further determines the remaining finished product parameters;

[0084] If the peak spacing deviation parameter is not less than the peak spacing deviation value, the analysis module determines that the peak spacing of the wire sleeve is unqualified and adjusts the injection unit according to the peak spacing deviation parameter.

[0085] It is understandable that, for those skilled in the art, the peak spacing of the wire sleeve can be adjusted by adjusting the operating parameters of the injection molding machine and the shape of the mold, which will not be elaborated here.

[0086] Embodiment 2: Based on Embodiment 1, this embodiment is different from it in that the standard value of the peak spacing is 10 mm, and the peak spacing deviation value is 1 mm. If the peak spacing of the wire sleeve is 10 mm, the peak spacing deviation parameter is 0 mm, which is less than the peak spacing deviation value of 1 mm. The analysis module determines that the peak spacing of the wire sleeve is qualified, and further determines the remaining parameters of the finished product;

[0087] If the wave peak spacing of the wire sleeve is 12 mm, and the wave peak spacing deviation parameter is 2 mm, which is greater than the wave peak spacing deviation value of 1 mm, the analysis module determines that the wave peak spacing of the wire sleeve is unqualified and adjusts the injection unit according to the wave peak spacing deviation parameter.

[0088] Among them, the standard value of the peak spacing is negatively correlated with the maximum curvature of the wire sleeve; the peak spacing deviation value is negatively correlated with the maximum curvature of the wire sleeve.

[0089] In one embodiment, when the maximum curvature of the wire sleeve is 30 degrees, the standard value of the peak spacing is 20 mm, and the peak spacing deviation value is 3 mm;

[0090] When the maximum curvature of the wire sleeve is 45 degrees, the standard value of the peak spacing is 15 mm, and the peak spacing deviation value is 2 mm;

[0091] When the maximum curvature of the wire sleeve is 60 degrees, the standard value of the peak spacing is 10 mm and the peak spacing deviation value is 1 mm.

[0092] Specifically, the analysis module compares the inner diameter length of the pipe mouth of the wire sleeve detected by the detection module with the standard value of the inner diameter length of the pipe mouth to obtain the inner diameter length deviation parameter of the pipe mouth, and compares the inner diameter length deviation parameter of the pipe mouth with the inner diameter length deviation value of the pipe mouth to determine whether the inner diameter length of the pipe mouth of the wire sleeve is qualified;

[0093] If the pipe mouth inner diameter length deviation parameter is less than the pipe mouth inner diameter length deviation value, the analysis module determines that the pipe mouth inner diameter length of the wire sleeve is qualified, and further determines the remaining finished product parameters;

[0094] If the nozzle inner diameter length deviation parameter is not less than the nozzle inner diameter length deviation value, the analysis module determines that the nozzle inner diameter length of the wire sleeve is unqualified and adjusts the injection unit according to the nozzle inner diameter length deviation parameter.

[0095] It is understandable that, for those skilled in the art, the inner diameter length of the pipe mouth of the wire sleeve can be adjusted by adjusting the operating parameters of the injection molding machine and the shape of the mold, which will not be elaborated here.

[0096] Embodiment 3: Based on Embodiment 2, this embodiment is different from it in that the standard value of the inner diameter length of the pipe mouth is 5 mm, and the inner diameter length deviation value of the pipe mouth is 1 mm. If the inner diameter length of the pipe mouth of the wire sleeve is 5 mm, the inner diameter length deviation parameter of the pipe mouth is 0 mm, which is less than the inner diameter length deviation value of 1 mm. The analysis module determines that the inner diameter length of the pipe mouth of the wire sleeve is qualified, and further determines the remaining parameters of the finished product;

[0097] If the inner diameter length of the pipe mouth of the wire sleeve is 7 mm, and the inner diameter length deviation parameter of the pipe mouth is 2 mm, which is greater than the inner diameter length deviation value of 1 mm, the analysis module determines that the inner diameter length of the pipe mouth of the wire sleeve is unqualified and adjusts the injection unit according to the inner diameter length deviation parameter of the pipe mouth.

[0098] Among them, the standard value of the inner diameter length of the pipe mouth is positively correlated with the cross-sectional area of ​​the cable in the wire sheath; the deviation value of the inner diameter length of the pipe mouth is positively correlated with the cross-sectional area of ​​the cable in the wire sheath.

[0099] It is understandable that the larger the cross-sectional area of ​​the cable in the sheath is, the thicker the sheath is required to be and the larger the inner diameter length of the tube opening is.

[0100] In one embodiment, when the cross-sectional area of ​​the cable in the wire sheath is 10 square millimeters, the standard value of the inner diameter length of the pipe mouth is 15 millimeters, and the deviation value of the inner diameter length of the pipe mouth is 1 millimeter;

[0101] When the cross-sectional area of ​​the cable in the sheath is 20 square millimeters, the standard value of the inner diameter length of the tube mouth is 25 millimeters, and the deviation value of the inner diameter length of the tube mouth is 2 millimeters;

[0102] When the cross-sectional area of ​​the cable in the wire sheath is 30 square millimeters, the standard value of the inner diameter length of the pipe mouth is 35 millimeters, and the deviation value of the inner diameter length of the pipe mouth is 3 millimeters.

[0103] Specifically, the analysis module compares the wall thickness of the wire sleeve detected by the detection module with the standard value of the wall thickness to obtain a wall thickness deviation parameter, and compares the wall thickness deviation parameter with the wall thickness deviation value to determine whether the wall thickness of the wire sleeve is qualified;

[0104] If the pipe wall thickness deviation parameter is less than the pipe wall thickness deviation value, the analysis module determines that the pipe wall thickness of the wire sleeve is qualified;

[0105] If the tube wall thickness deviation parameter is not less than the tube wall thickness deviation value, the analysis module determines that the tube wall thickness of the wire sleeve is unqualified and adjusts the injection unit according to the tube wall thickness deviation parameter.

[0106] It is understandable that, for those skilled in the art, the tube wall thickness of the wire sleeve can be adjusted by adjusting the operating parameters of the injection molding machine and the shape of the mold, which will not be elaborated here.

[0107] Example 4: Based on Example 3, this example is different from Example 3 in that the standard value of the tube wall thickness is 3 mm, and the tube wall thickness deviation value is 0.5 mm. If the tube wall thickness of the wire sleeve is 3.1 mm, the tube wall thickness deviation parameter is 0.1 mm, which is less than the tube wall thickness deviation value of 0.5 mm. The analysis module determines that the tube wall thickness of the wire sleeve is qualified, and further determines the remaining parameters of the finished product.

[0108] If the wall thickness of the wire sleeve is 4 mm, and the wall thickness deviation parameter is 1 mm, which is greater than the wall thickness deviation value of 0.5 mm, the analysis module determines that the wall thickness of the wire sleeve is unqualified and adjusts the injection unit according to the wall thickness deviation parameter.

[0109] Among them, the standard value of pipe wall thickness is positively correlated with the number of cables in the sheath; the deviation value of pipe wall thickness is positively correlated with the number of cables in the sheath.

[0110] It is understandable that the more cables there are in the cable sheath, the greater the compression of the cable sheath at the cable bending position, and therefore, the greater the thickness of the cable sheath wall.

[0111] In one embodiment, when the number of cables in the cable sheath is 5, the standard value of the tube wall thickness is 15 mm, and the deviation value of the tube wall thickness is 1 mm;

[0112] When there are 10 cables in the sheath, the standard value of the tube wall thickness is 25 mm, and the deviation value of the tube wall thickness is 2 mm;

[0113] When there are 15 cables in the wire sheath, the standard value of the pipe wall thickness is 35 mm and the deviation value of the pipe wall thickness is 3 mm.

[0114] Specifically, the analysis module counts the parameters of the finished product of the wire sleeve, and determines whether the wire sleeve is qualified by comparing the parameters of the finished product. While ensuring the quality of the wire sleeve, the accuracy of the wire sleeve quality judgment and the injection molding efficiency of the wire sleeve are further improved.

[0115] Specifically, the analysis module obtains the corrugation quantity deviation parameter, wave peak spacing deviation parameter, pipe mouth inner diameter length deviation parameter and pipe wall thickness deviation parameter of the qualified wire sleeve, and calculates the comprehensive deviation parameter according to each deviation parameter and the weight coefficient.

[0116] ;

[0117] Where: —Comprehensive deviation parameter;

[0118] —Weight coefficient of ripple quantity;

[0119] —peak spacing weight coefficient;

[0120] —weight coefficient of the inner diameter of the pipe mouth;

[0121] —weight coefficient of pipe wall thickness;

[0122] a—ripple quantity deviation parameter;

[0123] b—peak spacing deviation parameter;

[0124] c—pipe mouth inner diameter length deviation parameter;

[0125] d—Pipe wall thickness deviation parameter.

[0126] Example 5: Based on Example 4, this example differs from it in that the analysis module obtains the corrugation number deviation parameter of the qualified wire sleeve as 0, the peak spacing deviation parameter as 0, the pipe mouth inner diameter length deviation parameter as 0 and the pipe wall thickness deviation parameter as 0.1, and the weight coefficients are 0.5, 0.2, 0.2, and 0.1 respectively; the comprehensive deviation coefficient is 0.01.

[0127] Specifically, the analysis module compares the comprehensive deviation parameter with the comprehensive deviation value.

[0128] If the comprehensive deviation parameter is less than the comprehensive deviation value, the analysis module determines that the wire sleeve is qualified;

[0129] If the comprehensive deviation parameter is not less than the comprehensive deviation value, the analysis module determines that the wire sleeve is unqualified and adjusts the injection unit according to the comprehensive deviation parameter;

[0130] It is understandable that for those skilled in the art, the number of corrugations, peak spacing, inner diameter length of the pipe mouth and wall thickness of the wire sleeve can be adjusted by adjusting the operating parameters of the injection molding machine and the shape of the mold, thereby adjusting the comprehensive deviation parameters, which will not be repeated here.

[0131] Embodiment 6: Based on Embodiment 5, this embodiment is different from it in that the comprehensive deviation value is 0.1. If the comprehensive deviation parameter is 0.01, which is less than the comprehensive deviation value 0.1, the analysis module determines that the wire sleeve is qualified;

[0132] If the comprehensive deviation parameter is 1 and is greater than the comprehensive deviation value 0.1, the analysis module determines that the wire sleeve is unqualified and adjusts the injection unit according to the comprehensive deviation parameter;

[0133] Among them, the comprehensive deviation value is positively correlated with the maximum curvature of the wire sleeve.

[0134] In one embodiment, when the maximum curvature of the wire sleeve is 30 degrees, the comprehensive deviation value is 0.1;

[0135] When the maximum curvature of the wire sleeve is 45 degrees, the comprehensive deviation value is 0.2;

[0136] When the maximum curvature of the wire sleeve is 60 degrees, the comprehensive deviation value is 0.3.

[0137] Specifically, the analysis module comprehensively determines the parameters of each finished product, so that the determination of whether the size of the wire sleeve is qualified is more accurate. While ensuring the quality of the wire sleeve, the accuracy of the wire sleeve quality determination and the injection molding efficiency of the wire sleeve are further improved.

[0138] Specifically, the analysis module is externally connected to an audio-visual display screen for receiving the determination information of the analysis module and for the user end to control the injection molding module through the audio-visual display screen;

[0139] The determination information includes the determination result of each finished product parameter by the analysis module.

[0140] Specifically, the analysis module adjusts the injection molding module according to each determination result, thereby ensuring the quality of the wire sleeve and further improving the accuracy of the wire sleeve quality determination and the injection molding efficiency of the wire sleeve of the present invention.
