DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0030] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] like Figures 1 to 10 As shown, the utility model is a cutting device for polyolefin cables, comprising: a machine table 1, an installation box 3 installed on the top of the machine table 1, a feeding unit 2 for conveying and feeding the polyolefin cables, a cleaning mechanism for cleaning the polyolefin cables during feeding, and a cutting mechanism for cutting the cleaned polyolefin cables; a partition is fixedly installed on the inner wall of the installation box 3, and wire openings are opened on the partition and the side walls of the installation box 3.

[0032] By setting the feeding unit 2, the polyolefin cable can be fed and transported. The feeding unit 2 includes two conveyor belts arranged up and down, and an adjusting component for adjusting the distance between the two conveyor belts. U-shaped blocks are installed on the surfaces of the two conveyor belts. The material of the U-shaped blocks is preferably rubber. By passing the polyolefin cable through the two conveyor belts and adjusting the distance between the two conveyor belts by the adjusting component, the U-shaped block on the side where the two conveyor belts are close to each other clamps and fixes the outer edge of the polyolefin cable. At this time, the polyolefin cable can be transported to the installation box 3 by rotating the conveyor belt. Since the U-shaped block is made of rubber, the distance between the two conveyor belts can be increased. The friction force on the surface of the polyolefin cable is added, so that the polyolefin cable can be stably conveyed, and a certain buffering and protective effect can be played on the surface of the polyolefin cable. The adjusting component is preferably arranged with a threaded rod and two threaded blocks, and the outer edge of the threaded rod is provided with two sections of threads in opposite directions. The two threaded blocks are respectively threadedly installed on both sides of the threaded rod and fixedly installed with the adjacent conveyor belt. Through the rotation of the threaded rod, the two threaded blocks can be driven to approach and move away from each other, and then the conveyor belts can be driven to approach and move away from each other, so that the distance between the conveyor belts can be adjusted, and then the polyolefin cable can be clamped and conveyed.

[0033] One end of the polyolefin cable passes through the installation box 3 and the wire opening on the side wall of the partition. The present application also needs to be used in conjunction with a winding roller for winding up the polyolefin cable so that the cable can be conveyed and wound up simultaneously. The winding roller is a common winding roller on the market and will not be described in detail here. The cleaned cable can be wound up by the winding roller. When it is wound up to a certain length, the cutting mechanism is started to cut the cable.

[0034] The cleaning mechanism includes: a cleaning unit for cleaning dust on the surface of the polyolefin cable, a dust removal unit for sucking away the cleaned dust, and a motor 4 for driving the cleaning unit and the dust removal unit to operate synchronously; the cleaning unit includes: a rotating rod rotatably mounted on the side wall of the inner cavity of the installation box 3, a cleaning cylinder 9 and a linkage gear 20 fixedly sleeved on the outer edge of the rotating rod, a rotating shaft rotatably mounted on the top of the inner cavity of the installation box 3, a fan 5 and an active bevel gear 6 fixedly sleeved on the bottom end of the rotating shaft, a driven bevel gear 7 meshingly mounted on one side of the active bevel gear 6, a linkage shaft fixedly mounted on one side of the driven bevel gear 7, and a transmission member 8 for transmitting between the linkage shaft and the rotating rod;

[0035] During cleaning, by starting the motor 4 and the air pump 11, the power output shaft of the motor 4 is fixedly connected to the top of the rotating shaft, thereby driving the active bevel gear 6 and the fan 5 to rotate, and the driven bevel gear 7 is driven to rotate through the active bevel gear 6, and then the cleaning cylinder 9 can be driven to rotate through the transmission member 8. Since the two linkage gears 20 are meshed with each other, the two cleaning cylinders 9 rotate relatively, so that the dust on the surface of the cable can be cleaned. Since the outer edge of the cleaning cylinder 9 is set as a soft brush, when the cable moves from the soft brush, the soft brushes on both sides can comprehensively clean the dust on the outer edge of the cable, thereby improving the cleaning effect. The setting of the soft brush will not scratch the surface of the cable, thereby ensuring the cleaning effect and protecting the surface of the cable. At the same time, air is blown downward through the rotation of 5, so that the swept dust can be blown into the dust collecting hopper.

[0036] It is supplemented here that the transmission member 8 is preferably a transmission method of a pulley and a belt.

[0037] The dust removal unit includes: a collecting box 10 fixedly installed at the bottom of the inner cavity of the installation box 3, a dust collecting hopper plugged into the top of the collecting box 10, a sealing door hingedly installed on one side of the collecting box 10, a slide groove opened on the inner wall of the collecting box 10, a slide bar slidably installed in the inner cavity of the slide groove, a filter screen 19 fixedly installed on one side of the slide bar, an air pump 11 fixedly installed on the outside of the installation box 3, an air inlet pipe plugged between the collecting box 10 and the air pump 11, and an air outlet pipe plugged between the air pump 11 and the side wall of the installation box 3.

[0038] While cleaning the dust, the air in the inner cavity of the collection box 10 can be sucked out by the air pump 11 and transported to the top of the fan 5. Since the air in the inner cavity of the collection box 10 is sucked out, a negative pressure is formed in the inner cavity of the collection box 10, so that the air in the dust hopper can be sucked into the inner cavity of the collection box 10, and then the dust enters the inner cavity of the collection box 10 with the flow of air to be collected. By adopting the method of blowing air from above and sucking air from below, the air in the inner cavity of the installation box 3 forms a circulating flow, which avoids the floating of the cleaned dust in the inner cavity of the installation box 3, speeds up the dust removal efficiency, and improves the dust removal effect.

[0039] By setting the filter 19, the air entering the inner cavity of the collection box 10 can be filtered, so that the dust is retained on the top of the filter 19, and the filtered air is circulated to the inner cavity of the installation box 3 through the air inlet pipe, so that the air entering the inner cavity of the installation box 3 through the air outlet pipe is clean air, and dust will not be brought into the inner cavity of the installation box 3, thereby further improving the dust removal effect.

[0040] When dust removal is completed, the filter 19 can be pulled out by opening the sealing door and through two slide bars, and then the dust on the top of the filter 19 can be cleaned, and then the cleaned filter 19 can be put back into the inner cavity of the collection box 10, so that the dust can be collected and processed conveniently.

[0041] The dust removal mechanism can completely clean the dust on the cable surface, and collect the cleaned dust simultaneously, thus avoiding the wear and tear of the cable when it is rolled up, and improving the production quality of the cable.

[0042] The cutting mechanism includes: a cylinder 12 fixedly mounted on the top of the installation box 3, a movable plate 13 fixedly mounted on the movable end of the cylinder 12, a spring guide rod 14 movably mounted on the side wall of the movable plate 13, a pressure block 16 fixedly mounted on the bottom end of the spring guide rod 14, a cutting knife 18 fixedly mounted on the bottom center of the movable plate 13, a cutting table 17 fixedly mounted on the inner wall of the installation box 3, a limiting rod 15 installed through the side wall of the movable plate 13, a limiting groove is provided on the side of the pressure block 16 close to the cutting table 17, and cutting grooves are provided on the side walls of the pressure block 16 and the cutting table 17, and a storage box is movably mounted on the bottom of the inner cavity of the installation box 3, and the storage box is located directly below the cutting table 17.

[0043] When the winding roller is wound to the required length, the feeding unit 2 and the winding roller stop running. At the same time, the cylinder 12 is started to drive the movable plate 13 downward, and the cutting knife 18 and the spring guide rod 14 are driven downward by the movable plate 13. The spring guide rod 14 drives the pressing block 16 downward. Since the pressing block 16 is located at the bottom of the cutting knife 18, the pressing block 16 contacts the cable before the cutting knife 18. When the pressing block 16 abuts against the outer edge of the cable, the pressing block 16 no longer moves downward. At this time, the cable is located in the inner cavity of the limit groove between the pressing block 16 and the cutting table 17. At the same time, the movable plate 13 drives the cutting knife 18 to continue to move downward, thereby driving the spring guide rod 14 to be compressed. Through the elastic force of the spring guide rod 14, the pressing block 16 maintains the squeezing state of the cable. Through the mutual cooperation of the pressing block 16 and the cutting table 17, the cable can be pressed and fixed, avoiding the cable from being located during cutting, improving the stability during cutting, avoiding the uneven cutting edge, and thus improving the cutting effect.

[0044] When the cutting knife 18 moves downward and passes through the two cutting grooves, the cable can be cut. The debris generated when cutting the cable can fall into the inner cavity of the storage box through the cutting groove on the cutting table 17 for collection. After the cutting is completed, the cylinder 12 is started to drive the cutting knife 18 to move upward. At this time, the cutting knife 18 moves upward before the pressing block 16. When the cutting knife 18 moves upward from the inner cavity of the cutting groove on the pressing block 16, the cutting debris attached to the outer edge of the cutting knife 18 can be scraped off through the inner wall of the cutting groove to prevent the debris from adhering to the surface of the cutting knife 18 and affecting the cutting effect.

[0045] The present application also includes: a PLC controller, a timer, and the PLC controller is electrically connected to the timer, the feeding unit 2, the motor 4, the cylinder 12, and the winding roller. The specific steps are as follows:

[0046] Step S1: set feeding time T1; cutting time T2;

[0047] Step S2: When the device is started, the PLC controller controls the starting feeding unit 2 to uniformly convey the cable to the installation box 3. At the same time, the PLC controller starts the motor 4 and the winding roller, which can remove dust during the cable feeding process, thereby achieving feeding, dust removal and winding at the same time, so that the cable winding effect is good. At the same time, the PLC controller starts the timer;

[0048] Step S3: When the feeding time T1 set by the timer is reached, that is, the cable reaches the required length, the PLC controller controls the feeding unit 2 to stop feeding into the installation box 3, and controls the motor 4 and the winding roller to stop working; at the same time, the PLC controller controls the cylinder 12 to start, thereby driving the cutting knife 18 to move downward to cut the cable;

[0049] Step S4: When the timer reaches the set cutting time T2, the cutting is completed, and the PLC controller controls the cylinder 12 to drive the cutting knife 18 to reset upward, thereby completing the cutting of the cable.

[0050] Working principle: When in use, start the feeding unit 2 to convey the cable to the inner cavity of the installation box 3. At this time, the cable is dusted and cleaned by the dust removal mechanism, and the dust-removed cable is reeled up by the reeling roller, realizing feeding, dust removal and reeling at the same time. When the cable has been reeled to the required length, stop feeding and reeling, and start the cutting mechanism to cut the cable.
