Description

Technical Field

[0001] This utility model relates to the field of PVC pipe cutting technology, specifically a PVC pipe cutting positioner. Background Technology

[0002] PVC pipe is mainly composed of polyvinyl chloride, with other components added to enhance its heat resistance, toughness, and ductility. During the production and processing of PVC pipe, longer PVC pipes need to be cut to make them easier to pack and transport.

[0003] Publication No. CN220463989U discloses a PVC pipe cutting and positioning device. This device places the PVC pipe in a grooved plate connected to the upper end of a main board. A hydraulic cylinder is connected to a support plate. The extension and retraction of the hydraulic cylinder causes a cutting blade connected to the lower end to cut the PVC pipe. During cutting, a clamping plate is fixed to the upper end of a fixing block with bolts, allowing the PVC pipe to pass through the clamping plate and preventing skewing during cutting. Finally, the length of the PVC pipe is obtained by adding the values ​​on the scale of the support plate to the values ​​on the telescopic scale plate. Rotating a knob causes a screw to fix the telescopic scale plate to the main board. However, this patent still has the following problems in actual use:

[0004] The device has a cutting device connected to the upper part of the support plate, which cuts the PVC pipe. During cutting, the anti-skewing device fixes the PVC pipe to prevent it from tilting. Finally, the length of the PVC pipe is measured by a measuring device, which allows for adjustment of the cutting length. However, when cutting longer pipes, the device may need to be moved to one end of the pipe and slowly moved along the pipe to the target area, which greatly reduces the efficiency of pipe cutting and causes inconvenience to the operators.

[0005] A PVC pipe cutting and positioning device is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a PVC pipe cutting and positioning device to solve the problems mentioned in the background art. Currently, the cutting device is connected to the upper end of a support plate to cut the PVC pipe. During cutting, the PVC pipe is fixed by an anti-skewing device to prevent it from tilting. Finally, the length of the PVC pipe is measured by a measuring device, which allows for adjustment of the cutting length. However, when cutting longer pipes, this device may need to be moved to one end of the pipe and slowly moved along the pipe to the target area, which greatly reduces the efficiency of pipe cutting.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PVC pipe cutting and positioning device, including a base, a cutting groove is provided on the top of the base, and support blocks are symmetrically fixedly installed on the bottom of the base; a cutting mechanism is provided on the top of the base, and a clamping component is provided inside the base;

[0008] The cutting mechanism includes a mounting frame on the top of the base, with a support plate symmetrically fixedly mounted on one side of the top of the base. A rotating shaft is fixedly mounted inside the bottom side of the mounting frame, with both ends of the rotating shaft passing through the support plate and rotatably connected to it. A grooved plate is fixedly mounted on one side of the top of the base, and the bottom side of the mounting frame is inserted into the inner side of the grooved plate. A limit box is symmetrically fixedly mounted on the top side of the base near the grooved plate, and a limit frame is fixedly mounted on one side of the limit box. A threaded rod is rotatably connected inside the limit box, and a trapezoidal plate is threadedly connected to the outside of the threaded rod. A pressing rod is slidably connected between the limit box and the limit frame, and a push plate is fixedly mounted on the end of the pressing rod away from the limit box. A first compression spring is sleeved on the outside of the pressing rod. Slots are symmetrically opened on one side of the bottom of the mounting frame, and a plug is welded to one side of the push plate, with the plug inserted into the slot.

[0009] Preferably, an electric retractable rod is fixedly installed inside the upper part of the mounting frame, and a cutting blade is fixedly installed at the bottom of the electric retractable rod. Guide rods are symmetrically slidably connected inside the upper part of the mounting frame, and the bottom of the guide rods is fixedly connected to the cutting blade. A second retraction spring is sleeved on the outer side of the bottom of the guide rods.

[0010] Preferably, the clamping assembly includes symmetrically opened grooves on the top of the base, and a bidirectional screw is rotatably connected between the groove and the base. Threaded blocks are symmetrically threaded to both ends of the bidirectional screw, and an L-plate is fixedly installed on the top of the threaded blocks. Sprockets are symmetrically fixedly installed at both ends of the bidirectional screw, and a chain is meshed between the outer sides of the sprockets. A rubber pad is fixedly installed on the inner side of the L-plate.

[0011] Preferably, a stop is fixedly installed on the top of the guide rod.

[0012] Preferably, a rotating block is fixedly installed at one end of the bidirectional screw.

[0013] Preferably, the threaded block is disposed inside the slide groove and is slidably connected to the slide groove.

[0014] Preferably, the trapezoidal plate is disposed inside the limiting box and is slidably connected to the limiting box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A PVC pipe cutting and positioning device is described, in detail, as follows: The operator rotates the mounting frame between the support plates. When the mounting frame rotates and inserts into the grooved plate, the operator then rotates two sets of threaded rods inside the limiting box. The rotation of the threaded rods causes the trapezoidal plate to slide inside the limiting box. When the trapezoidal plate moves downward, its surface slope presses against the extrusion rod. At this time, the extrusion rod slides inside the limiting box and the limiting frame. Simultaneously, the first contraction spring extends and resets, allowing multiple sets of inserts to engage with the slots. This enables rapid adjustment and fixation of the mounting frame, facilitating quick deployment by the operator according to the PVC pipe cutting position. This method significantly improves PVC pipe cutting efficiency, offering greater convenience compared to existing technologies that require workers to thread the PVC pipe through the equipment. It greatly enhances the flexibility of the device. By rotating a bidirectional screw, the operator drives two sets of threaded blocks to slide within the groove. The movement of the threaded blocks moves the L-plates, and through the cooperation of the sprocket and chain, the two sets of L-plates move synchronously relative to each other. This mutual movement of the two L-plates compresses and limits the PVC pipe on both sides. The rubber pads deform under this compression, achieving a rapid and fixed limit on the PVC pipe cutting area. This effectively prevents the PVC pipe from shifting during cutting, thus greatly improving the stability of PVC pipe cutting.

[0016] 1. The operator rotates the mounting frame between the support plates. At this time, both ends of the rotating shaft rotate inside the support plates. After the mounting frame rotates and inserts into the grooved plate, the PVC pipe is located at the top of the base and inside the mounting frame. The operator then rotates two sets of threaded rods inside the limiting box. The rotation of the threaded rods causes the trapezoidal plate to slide inside the limiting box. When the trapezoidal plate moves downwards, the surface slope presses against the extrusion rod. At this time, the extrusion rod slides inside the limiting box and the limiting frame. The first contraction spring then extends and resets, allowing multiple sets of inserts to connect with the slots, thus enabling rapid mounting of the frame. The adjustable and fixed effect allows workers to quickly deploy the equipment according to the PVC pipe cutting position, thereby greatly improving the PVC pipe cutting efficiency. Compared with the existing technology that requires workers to pass the PVC pipe through the equipment, this method is more convenient and greatly improves the flexibility of the device during use. It brings convenience to workers when using the equipment. When the worker starts the electric retraction rod, it drives the cutting blade to move down to cut the PVC pipe. At this time, the movement of the cutting blade causes the two sets of guide rods to slide inside the installation frame. At this time, the second retraction spring extends or retracts, thereby achieving the effect of the cutting blade cutting the PVC pipe quickly and stably.

[0017] 2. By rotating the bidirectional screw, the operator drives two sets of threaded blocks to slide inside the groove. The movement of the threaded blocks causes the L-plate to move, moving it in a convergence and unfolding trajectory. The rotation of the bidirectional screw drives the rotation of two sets of sprockets. Through the cooperation between the sprockets and the chain, the two sets of L-plates move synchronously relative to each other, thus squeezing and limiting the two sides of the PVC pipe. At this time, the rubber pad is deformed by the compression, which can quickly fix and limit the cutting area of ​​the PVC pipe, effectively preventing the PVC pipe from shifting during the cutting process. This greatly improves the stability of PVC pipe cutting and brings convenience to the operator. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides a technical solution: a PVC pipe cutting and positioning device, including a base 1, a knife groove 101 is provided on the top of the base 1, and support blocks 102 are symmetrically fixedly installed on the bottom of the base 1; a cutting mechanism 2 is provided on the top of the base 1, and a clamping component 3 is provided inside the base 1.

[0026] The cutting mechanism 2 includes a mounting frame 201 disposed on the top of the base 1. A support plate 202 is symmetrically fixedly mounted on one side of the top of the base 1. A rotating shaft 203 is fixedly mounted inside the bottom side of the mounting frame 201, with both ends of the rotating shaft 203 passing through the support plate 202 and rotatably connected to it. A grooved plate 204 is fixedly mounted on one side of the top of the base 1, and the bottom side of the mounting frame 201 is inserted into the inner side of the grooved plate 204. A limiting box 205 is symmetrically fixedly mounted on the top side of the base 1 near the grooved plate 204. A limiting frame 206 is fixedly mounted on one side of the limiting box 205. A threaded rod 207 is rotatably connected inside the limiting box 205, and a trapezoidal plate 208 is threadedly connected to the outside of the threaded rod 207. The trapezoidal plate 208 is disposed inside the limiting box 205 and connected to the limiting box 206. The 05 is slidably connected, and the limiting box 205 and the limiting frame 206 are slidably connected with an extrusion rod 209. The end of the extrusion rod 209 away from the limiting box 205 is fixedly installed with a push plate 210. The extrusion rod 209 is sleeved with a first contraction spring 211. The bottom side of the mounting frame 201 is symmetrically provided with slots 212. The push plate 210 is welded with a plug 213 on one side. The plug 213 is inserted into the slot 212, thereby achieving the effect of quickly adjusting and fixing the mounting frame 201. This makes it easier for workers to quickly deploy according to the PVC pipe cutting position, thereby greatly improving the PVC pipe cutting efficiency. Compared with the existing technology, which requires workers to pass the PVC pipe through the equipment, this method is more convenient and greatly improves the flexibility of the device during use, bringing convenience to the workers.

[0027] An electric retractable rod 214 is fixedly installed inside the upper part of the mounting frame 201, and a cutting blade 215 is fixedly installed at the bottom of the electric retractable rod 214. Guide rods 216 are symmetrically slidably connected inside the upper part of the mounting frame 201, and the bottom of the guide rods 216 is fixedly connected to the cutting blade 215. A second retraction spring 217 is sleeved on the outer side of the bottom of the guide rods 216. When the operator starts the electric retractable rod 214, the cutting blade 215 moves down to cut the PVC pipe. At this time, the movement of the cutting blade 215 causes the two sets of guide rods 216 to slide inside the mounting frame 201. At this time, the second retraction spring 217 extends or retracts, thereby achieving the effect of the cutting blade 215 cutting the PVC pipe quickly and stably. A stop block 218 is fixedly installed on the top of the guide rod 216. Through the design of the stop block 218, the separation of the guide rod 216 from the mounting frame 201 can be effectively prevented.

[0028] The clamping assembly 3 includes symmetrically arranged grooves 301 on the top of the base 1, and a bidirectional screw 302 is rotatably connected between the groove 301 and the base 1. Threaded blocks 303 are symmetrically threaded to both ends of the bidirectional screw 302. The threaded blocks 303 are located inside the groove 301 and slidably connected to it. An L-plate 304 is fixedly installed on the top of the threaded blocks 303. Sprockets 305 are symmetrically fixedly installed at both ends of the bidirectional screw 302, and a chain 306 is meshed between the sprockets 305. A rubber pad 307 is fixedly installed on the inner side of the L-plate 304. A rotating block 308 is fixedly installed at one end of the bidirectional screw 302. This allows for rapid fixation and limiting of the PVC pipe cutting area, effectively preventing the PVC pipe from shifting during cutting, thus greatly improving the stability of PVC pipe cutting and providing convenience for operators. The rotating block 308 facilitates operation of the bidirectional screw 302.

[0029] Working principle: Before using this type of PVC pipe cutting and positioning device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, firstly, the worker uses a measuring tape and marker to measure the position where the PVC pipe needs to be cut. Then, the worker places the base 1 at the marked position on the PVC pipe. At this time, the worker rotates the mounting frame 201 between the support plates 202. At this time, the two ends of the rotating shaft 203 are respectively located inside the support plate 202 and rotate. When the mounting frame 201 rotates and is inserted into the groove plate 204, the PVC pipe is located on the top of the base 1 and inside the mounting frame 201. Then, the worker rotates the two sets of threaded rods 207 inside the limiting box 205. The rotation of the threaded rods 207 causes the trapezoidal plate 208 to slide inside the limiting box 205. When the trapezoidal plate 208 moves down, the surface slope squeezes the extrusion rod 209. At this time, the extrusion rod 209 slides inside the limiting box 205 and the limiting frame 206. At this time, the first contraction spring 211 extends and resets, thereby causing the multiple sets of inserts 213 to... The slots 212 are connected to each other, which enables quick adjustment and fixation of the mounting frame 201. This allows workers to quickly deploy the equipment according to the PVC pipe cutting position, greatly improving the PVC pipe cutting efficiency. Compared with the existing technology that requires workers to pass the PVC pipe through the equipment, this method is more convenient and greatly improves the flexibility of the device. It also brings convenience to the workers. When the worker starts the electric retraction rod 214, it drives the cutting blade 215 to move down to cut the PVC pipe. At this time, the movement of the cutting blade 215 causes the two sets of guide rods 216 to slide inside the mounting frame 201. At this time, the second retraction spring 217 extends or retracts, which enables the cutting blade 215 to quickly and stably cut the PVC pipe. The design of the stop block 218 can effectively prevent the guide rods 216 from separating from the mounting frame 201.

[0030] The operator rotates the bidirectional screw 302, causing two sets of threaded blocks 303 to slide inside the groove 301. The movement of the threaded blocks 303 drives the movement of the L-plate 304, which moves along a convergence and unfolding trajectory. The rotation of the bidirectional screw 302 drives the rotation of two sets of sprockets 305. Through the cooperation between the sprockets 305 and the chain 306, the two sets of L-plates 304 move synchronously relative to each other, thereby squeezing and limiting the two sides of the PVC pipe. At this time, the rubber pad 307 is deformed by the compression, which can quickly fix and limit the PVC pipe cutting area, thus effectively preventing the PVC pipe from shifting during the cutting process. This greatly improves the stability of PVC pipe cutting and brings convenience to the operator. The design of the rotating block 308 makes it easy for the operator to operate the bidirectional screw 302.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
