[0002] PVC fiber-reinforced hoses are widely used in agricultural irrigation, industrial fluid transportation, and building drainage due to their excellent flexibility, pressure resistance, and corrosion resistance. Traditional PVC hoses are typically manufactured using a multi-layer co-extrusion process, where fiber reinforcement layers (such as polyester fiber and nylon mesh) are used to enhance tensile strength and pressure resistance.

[0003] When producing PVC fiber reinforced hoses, it is necessary to cut PVC fiber reinforced hoses of different specifications. In the existing technology, when cutting PVC fiber reinforced hoses, a mechanical baffle is used to block the PVC fiber reinforced hoses, and then the PVC fiber reinforced hoses are measured manually, and the PVC fiber reinforced hoses are cut according to the measurement results.

[0021] like Figure 1-7 As shown, the present invention proposes a fixed-distance slitting device, comprising: The support plate 100 and the conveying path 200 arranged on the support plate 100; the present invention is further provided with a support box 1100, and a plurality of height-adjustable support legs are provided at the bottom of the support box 1100; the support box 1100 is supported by the support legs to ensure that the support plate 100 is in a balanced state when in use; it should be noted that the support box 1100 and the support legs are both prior art and will not be further described in the present invention; in addition, the conveying path 200 in the present invention is preferably a V-shaped conveying path 200, so that when the PVC fiber reinforced hose is conveyed, a gap can be ensured between the PVC fiber reinforced hose and the conveying path 200, thereby reducing the friction between the PVC fiber reinforced hose and the conveying path 200, so that the resistance of the PVC fiber reinforced hose during conveyance is smaller; The feeding mechanism 300 is arranged at one end of the support plate 100 and is arranged adjacent to the inlet of the conveying channel 200; during the use stage, the PVC fiber reinforced hose continuously enters the conveying channel 200 under the action of the feeding mechanism 300 and is conveyed in the conveying channel 200; when the feeding mechanism 300 conveys the PVC fiber reinforced hose, it also measures the length of the PVC fiber reinforced hose and generates measurement data; in addition, a plurality of guide rollers 1200 are further arranged at a position adjacent to the feeding mechanism 300 on the support plate 100, and the plurality of guide rollers 1200 can buffer the friction between the PVC fiber reinforced hose and the support plate 100 before it enters the feeding mechanism 300; and can also reduce the friction between the PVC fiber reinforced hose and the support plate 100 during the subsequent continuous conveying process; preferably, the guide rollers 1200 are preferably 3; and they are inserted into the roller groove on the support plate 100; The inspection group 400 is disposed on the support plate 100 ; position information of the PVC fiber-reinforced hose is obtained by the inspection group 400 ; as the PVC fiber-reinforced hose is continuously pushed by the feeding mechanism 300 and conveyed within the conveying path 200 , the PVC fiber-reinforced hose is conveyed to the position of the inspection group 400 , and the PVC fiber-reinforced hose is inspected by the inspection group 400 ; specifically, position information of the PVC fiber-reinforced hose is obtained, which includes image information and length information; In addition, a protective cover 1300 is provided on the support plate 100 to cover the conveying path 200 between the feeding mechanism 300 and the detection group 400. When the feeding mechanism 300 conveys the PVC fiber-reinforced hose, the protective cover 1300 can limit the position of the PVC fiber-reinforced hose to prevent deformation of the PVC fiber-reinforced hose during conveyance on the conveying path 200. The cutting mechanism 500 is arranged on the support plate 100 and is arranged adjacent to the detection group 400, and a clamping group 600 is arranged between the cutting mechanism 500 and the detection group 400. The data measured by the feeding mechanism 300 and the detection group 400 are transmitted to the control mechanism. After the control mechanism calculates the actual length of the PVC fiber reinforced hose being fed, the clamping group 600 and the cutting mechanism 500 are controlled to operate. Specifically, the control mechanism activates the clamping group 600 to clamp the PVC fiber reinforced hose, ensuring that the PVC fiber reinforced hose does not deform excessively during the cutting process. After the clamping group 600 clamps the PVC fiber reinforced hose, the cutting mechanism 500 is activated to cut the PVC fiber reinforced hose. A plurality of discharge ports 701 are provided on the conveying path 200 below the cutting mechanism 500 and are arranged through the conveying path 200; and a dust removal mechanism 702 is provided on the support plate 100 on the opposite side of the cutting mechanism 500; the dust removal mechanism 702 generates negative pressure to convey the waste generated in the cutting process through the plurality of discharge ports 701 for collection; when the cutting mechanism 500 is in motion, the dust removal mechanism 702 is started by the control mechanism, and negative pressure is generated by the dust removal mechanism 702, and the negative pressure is transmitted to the conveying path 200 through the plurality of discharge ports 701; on the one hand, the negative pressure is used to adsorb the PVC fiber reinforced hoses located at the positions of the plurality of discharge ports 701 to ensure the stability of the PVC fiber reinforced hoses in the conveying path 200; on the other hand, when the PVC fiber reinforced hoses are cut by the cutting mechanism 500, the waste generated will enter the plurality of discharge ports 701 under the action of the negative pressure and be conveyed to the designated position by the dust removal mechanism 702; The discharge mechanism 800 is disposed adjacent to the cutting mechanism 500 and continues to convey the cut PVC fiber reinforced hose. It should be noted that when the PVC fiber reinforced hose is cut, a portion of the PVC fiber reinforced hose is placed in the discharge mechanism 800. The cooperation between the discharge mechanism 800 and the feeding mechanism 300 can keep the PVC fiber reinforced hose in a stretched state, thereby ensuring the accuracy of the cutting when the PVC fiber reinforced hose is cut. In addition, after the PVC fiber reinforced hose is cut, the discharge mechanism 800 continues to convey the PVC fiber reinforced hose to the distribution mechanism 900. The material dividing mechanism 900 is arranged on the support plate 100 and is adjacent to the discharging mechanism 800. The cut PVC fiber reinforced hose delivered by the discharging mechanism 800 is delivered to the collection position. After the PVC fiber reinforced hose delivered by the discharging mechanism 800 enters the material dividing mechanism 900, the material dividing mechanism 900 is controlled by the control mechanism to operate. During the operation, the PVC fiber reinforced hose is displaced and slides to the collection position, thereby completing the automatic cutting and collection operation of a section of PVC fiber reinforced hose. In addition, the control mechanism is respectively connected to the feeding mechanism 300, the detection group 400, the cutting mechanism 500, the dust removal mechanism 702, the discharging mechanism 800 and the dividing mechanism 900; during the use stage, the control mechanism can respectively obtain the data of the feeding mechanism 300, the detection group 400 and the dividing mechanism 900; and generate a start instruction to control the start and stop of the feeding mechanism 300, the detection group 400, the cutting mechanism 500, the dust removal mechanism 702, the discharging mechanism 800 and the dividing mechanism 900; in the present invention, the preferred control mechanism is a programmable PLC control board. Since the existing technology is adopted, the present invention will not further explain this.

[0022] The technical solution of the present invention can convey the PVC fiber reinforced hose into the conveying channel 200 through the feeding mechanism 300, and the PVC fiber reinforced hose is continuously conveyed under the action of the feeding mechanism 300 until the PVC fiber reinforced hose is conveyed to the position of the detection group 400, and the position information of the PVC fiber reinforced hose is obtained by the detection group 400, and the obtained position information is sent to the control mechanism. Under the action of the control mechanism, the PVC fiber reinforced hose is cut by the cutting mechanism 500, and the waste generated in the cutting process is collected during the cutting process through the cooperation of several discharge ports 701 and dust removal mechanisms 702; after the PVC fiber reinforced hose is cut, the cut PVC fiber reinforced hose is continued to be discharged through the discharge mechanism 800 The PVC fiber reinforced hose is conveyed to the dividing mechanism 900, and the PVC fiber reinforced hose is transported to the collection position through the dividing mechanism 900; compared with the prior art, the technical solution of the present invention can automatically convey, cut and dispose of waste of the PVC fiber reinforced hose without manual intervention, further reducing labor costs, and at the same time, the length of the PVC fiber reinforced hose that needs to be cut can be automatically measured during the conveying process, avoiding errors caused by manual measurement and improving the overall uniformity; in addition, through the cooperation of several discharge ports 701 and dust removal mechanisms 702, waste can be collected during the cutting process to avoid waste adhering to the PVC fiber reinforced hose, and there is no need to process the PVC fiber reinforced hose again, further shortening the overall workload.

The reinforced hose can adjust the distance between the feed roller 305 and the conveyor 200; preferably, the first support frame 301 and the second support frame 302 are provided with adjustment grooves; the first adjustment block 303 and the second adjustment block 304 are provided with blocks; in the installed state, the blocks are placed in the adjustment grooves, and can be slid in the adjustment grooves as needed, thereby changing the position of the first adjustment block 303 or the second adjustment block 304 on the first support frame 301 and the second support frame 302 to meet the needs of PVC fiber reinforced hoses with different diameters; Figure 4 As shown, movable grooves can be provided on the first support frame 301 and the second support frame 302, and the first adjustment block 303 and the second adjustment block 304 can be fixed by means of bolts passed through the movable grooves and connected to the first adjustment block 303 and the second adjustment block 304; a motor or a cylinder can also be provided inside the first support frame 301 and the second support frame 302, and the motor or cylinder can be connected through the first adjustment block 303 and the second adjustment block 304, and the positions of the first adjustment block 303 and the second adjustment block on the first support frame 301 and the second support frame 302 can be adjusted by the motor and the cylinder; Of course, when a motor or cylinder is used, it needs to be connected to a control mechanism, and the transmission distance of the PVC fiber reinforced hose is determined by obtaining the speed and running time of the first drive device 306; when the transmission distance of the PVC fiber reinforced hose is too low, the motor or cylinder can be adjusted, and then the vertical position of the feed roller 305 can be adjusted to change the pressure applied by the feed roller 305 to the PVC fiber reinforced hose, thereby changing the transmission speed of the PVC fiber reinforced hose.

[0024] Of course, the first adjustment frame 307 includes a fixed frame and a movable frame, and the fixed frame and the movable frame are slidably connected (such as the connection method of the movable groove and block between the first support frame 301 and the first adjustment block 303); at the same time, a motor or cylinder is provided on the fixed frame, and the position of the movable frame is adjusted by the motor or cylinder, thereby adjusting the position of the first driving device 306, wherein the motor or cylinder is connected to the control mechanism, and then under the control of the control mechanism, it can cooperate with the position adjustment of the first adjustment block 303 and the second adjustment block 304; in addition, a metering device 308 is provided on the movable frame, and when the movable frame is adjusted, the metering device 308 is adjusted at the same time; in this way, when the first driving device 306 rotates, it can ensure that the active wheel 382 drives the driving wheel 381 to rotate; in the present invention, the preferred metering device 308 is an encoder, and the metering device 308 is connected to the control mechanism, and the number of rotations of the first driving device 306 is obtained by the metering device 308, thereby obtaining the length of the PVC fiber reinforced hose being conveyed; and the obtained data is sent to the control device; like Figure 2 As shown, the detection group 400 includes a first detection device 401 and a second detection device 402. The first detection device 401 is set on the support plate 100 and connected to the control mechanism. The first detection device 401 obtains an image of the position groove 1004 on the outer surface of the PVC fiber reinforced hose on the conveyor 200 and transmits the obtained image to the control mechanism. The second detection device 402 is set on the support plate 100 and connected to the control mechanism.

Specifically, the second detection device 402 is a micro switch, and a position groove 1004 is provided on the surface of the PVC fiber reinforced hose. The position groove 1004 is opened on the outer surface of the PVC fiber reinforced hose. During normal conveying, the outer surface of the PVC fiber reinforced hose abuts against the second detection device 402, and when the position groove 1004 reaches the second detection device 402, the second detection device 402 is actuated, and the detection head of the second detection device 402 enters the position groove 1004. At this time, the second detection device 402 generates a position signal. As the PVC fiber reinforced hose continues to be conveyed, the position of the position groove 1004 on the outer surface of the PVC fiber reinforced hose changes, and the detection head of the second detection device 402 is squeezed by the outer surface of the PVC fiber reinforced hose and reset.

Specifically, the clamping cylinder 611 drives the clamping block 612 to move toward the position of the PVC fiber reinforced hose, and the PVC fiber reinforced hose is limited by the clamping groove 613. Of course, the clamping cylinder 611 can adjust the pressure under the control of the control mechanism. The actual adjustment is set according to the diameter of the PVC fiber reinforced hose, which will not be further described in the present invention. It should be further explained that the second clamping device 602 has the same structure as the first clamping device 601, but is only mirror-imaged. This will not be further described in the present invention. In addition, after the clamping groove 613 clamps the PVC fiber reinforced hose, when the cutter 503 cuts the PVC fiber reinforced hose, it can prevent the PVC fiber reinforced hose from lateral deformation, thereby ensuring the efficiency and effect of cutting. During cutting, the cutting cylinder 502 is activated, and drives the cutter 503 to move in the vertical direction to cut the PVC fiber reinforced hose. A cutting groove 101 is also provided on the support plate 100. The cutting groove 101 can ensure that the cutter 503 has sufficient movement distance to avoid incomplete cutting of the PVC fiber reinforced hose.

[0026] like Figure 1-3 As shown, after the PVC fiber reinforced hose is cut, it is further conveyed by the discharging mechanism 800, and the cut PVC fiber reinforced hose is conveyed to the dividing mechanism 900. When the cutting mechanism 500 cuts the PVC fiber reinforced hose, the PVC fiber reinforced hose can be put into a stretched state through the cooperation of the feeding mechanism 300 and the discharging mechanism 800, thereby improving the cutting effect. In the present invention, the structure of the discharging mechanism 800 is the same as that of the feeding mechanism 300. In order to save space, the specific structure of the discharging mechanism 800 will not be further described.

[0027] like Figure 5 and Figure 7As shown, the material distribution mechanism 900 includes: a discharge channel 901, a rotating block 902, a driving rod 903 and a discharge motor 905. The discharge channel 901 is provided with a rotating block 902 at both ends, and the rotating block 902 is rotatably provided on the support plate 100; the driving rod 903 is respectively connected to the rotating blocks 902 at both ends of the discharge channel 901, and the driving rod 903 is provided with a passive wheel 904; the action wheel on the output end of the discharge motor 905 is connected to the passive wheel 904; it should be noted that gears are provided at both ends of the driving rod 903, which mesh with the teeth on the rotating blocks 902 provided at both ends of the discharge channel 901; in this way, driven by the discharge motor 905, the driving rod 903 03 rotates, and then drives the discharge channel 901 to rotate through the rotating block 902, and after the rotation, the cut PVC fiber reinforced hose placed inside is detached; it should be noted that the rotating block 902 is connected to the support plate 100 axis, and then rotates with the axis connected to the support plate 100 as the axis when rotating; the passive wheel 904 set on the driving rod 903 is the first gear, and the action wheel on the discharge motor 905 is the second gear, and the first gear is engaged with the second gear; and then when the discharge motor 905 is actuated, it can drive the driving rod 903 to rotate; the preferred driving motor is a servo motor, and the speed and rotation direction can be adjusted under the control of the control mechanism.

[0028] In addition, a slide 907 is obliquely arranged on one side of the box body, and the slide 907 is arranged adjacent to the outlet of the discharge channel 901. When the discharge channel 901 rotates, the cut PVC fiber reinforced hose placed on the discharge channel 901 enters the slide 907 and slides on the slide 907 to the collection position for subsequent processing; in addition, it also includes a touch switch 906, which is arranged on the rotating block 902 away from one end of the discharge mechanism 800, and the touch switch 906 is connected to the control mechanism; the PVC fiber reinforced hose continues to move on the discharge channel 901, and when it contacts the touch switch 906, a contact signal is generated. After obtaining the contact signal, the control mechanism controls the discharge motor 905 to operate, completing the discharge operation of the cut PVC fiber reinforced hose; when the PVC fiber reinforced hose on the discharge channel 901 slides down, the contact switch is reset and a reset signal is generated. The control device controls the drive motor to move in the opposite direction and drives the discharge channel 901 to reset; the preferred contact switch is the touch switch 906.

[0029] like Figure 8 As shown, the present invention also proposes a fixed-distance slitting method, comprising the following steps: The PVC fiber reinforced hose is conveyed by the feeding mechanism 300, and the conveying length is recorded during the conveying process; when the PVC fiber reinforced hose is conveyed to the position of the detection group 400, the position information on the PVC fiber reinforced hose is detected by the detection group 400; specifically, the graphics and position signals of the position information on the PVC fiber reinforced hose are obtained by the detection group 400; the control mechanism obtains the detection data of the feeding mechanism 300 and the detection group 400, analyzes them, and determines the conveyed length of the PVC fiber reinforced hose, controls the clamping group 600 to clamp the PVC fiber reinforced hose, and controls the feeding mechanism 300 to stop the action; in the present invention, the length of the feeding mechanism 300 is measured. The length of the PVC fiber reinforced hose is determined by triple measurement data of depth data, image data and position data, so that the error of the detection result is small and the accuracy after cutting is improved; the cutting mechanism 500 and the dust removal mechanism 702 are controlled by the control mechanism to operate simultaneously, and the PVC fiber reinforced hose is cut by the cutting mechanism 500, and waste is collected by the dust removal mechanism 702 during the cutting process; the cutting mechanism 500 is reset, and the feeding mechanism 300 resumes action under the control of the control mechanism; the cut PVC fiber reinforced hose is conveyed to the dividing mechanism 900 by the discharging mechanism 800, and the cut PVC fiber reinforced hose is conveyed to the collection position by the dividing mechanism 900.

[0030] like Figure 9-11 As shown, the present invention also proposes a PVC fiber reinforced hose, comprising: Inner layer 1001, middle layer 1002 and outer layer 1003; the inner layer 1001, middle layer 1002 and outer layer 1003 are arranged in sequence from the inside to the outside; and the outside of the middle layer 1002 is a spirally wound polyester fiber grid; position grooves 1004 are arranged at equal intervals on the outer layer 1003; specifically, the inner layer 1001 is an antistatic PVC layer, and the outer layer 1003 is a UV anti-aging PVC layer; the inner layer 1001, middle layer 1002 and outer layer 1003 are co-extruded; and hot melt adhesive is pre-coated on the surface of the middle layer 1002 before molding to avoid delamination after subsequent molding; in addition, the hinge points of the polyester fiber grid on the middle layer 1002 are ultrasonically welded, which can improve the overall tensile strength after molding; it should be noted that a plurality of position grooves 1004 are arranged at intervals on the outer layer 1003, The distance between adjacent position slots 1004 can be preset, such as 1m or 2m. Thus, during subsequent use, the length of the PVC fiber-reinforced hose to be delivered is determined by the position slots 1004, and the PVC fiber-reinforced hose can then be cut at a predetermined distance in cooperation with the cutting mechanism 500. It should be noted that after the inner layer 1001, the middle layer 1002, and the outer layer 1003 are formed, the position slots 1004 are then formed in the outer layer 1003 using a distance-determining device, such as a hot press or a circular cutting device. In the present invention, the position slots 1004 are merely used as markings, so their width and depth do not need to be excessively large; a width and depth of 0.1 mm is sufficient. Of course, the width and depth of the position slots 1004 can also be adjusted according to the size of the PVC fiber-reinforced hose. Furthermore, in the subsequent cutting stage, the PVC fiber-reinforced hose can be processed according to the desired length in cooperation with the position slots 1004.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
