Description

Technical Field

[0001] The utility model belongs to the technical field of PE pipe cutting, and particularly relates to a device for cutting a PE water supply pipe to a fixed length. Background Art

[0002] The PE water supply pipe is a commonly used water conveyance pipe, which has the characteristics of high strength, corrosion resistance, non-toxicity, etc. Since the PE water supply pipe does not rust, it is an ideal pipe to replace the ordinary iron water supply pipe. After the PE water supply pipe is produced, it is necessary to cut the PE water supply pipe into a certain length according to the use needs. Since the length of the PE pipe is relatively long, in order to improve the cutting efficiency, the water pipe is usually fed continuously during cutting, but it is easy to cause the water pipe to hit the cutting tool during feeding, resulting in damage to the water pipe. Now, a structure that can realize intermittent feeding during cutting is proposed. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a device for cutting a PE water supply pipe to a fixed length, which solves the above problems.

[0004] To achieve the above object, the utility model is realized through the following technical solutions: A device for cutting a PE water supply pipe to a fixed length, including a frame, and further including: a feeding assembly for intermittent feeding; the feeding assembly includes shaft A, shaft B and a conveyor belt. The two shaft As and the two shaft Bs are symmetrically rotatably connected to the frame. The two shaft As cooperate with each other to drive the conveyor belt, and the two shaft Bs cooperate with each other to drive the conveyor belt.

[0005] Beneficial Effects

[0006] The utility model provides a device for cutting a PE water supply pipe to a fixed length, which has the following beneficial effects compared with the prior art:

[0007] The relevant technical personnel pass the PE pipe to be cut through between the two conveyor belts and pass it out between the sleeve A and the sleeve B. At this time, the relevant technical personnel start the motor, so that the axle fixedly connected to the center of the driving gear starts to rotate, so that the axle drives the eccentric wheel fixedly connected to it to rotate synchronously, so that the eccentric wheel drives the push rod rotatably connected to its eccentric part to start a circular motion, so that the push rod pushes the cutter head hinged to it, so that the cutter head starts to perform a linear reciprocating motion along its connection with the frame, so as to complete the cutting of the PE pipe through the cutter heads on both sides of the cutter head. After the cutting is completed, the cutter head starts to rise; at the same time, when the axle rotates, the pulley B fixedly connected to it rotates synchronously, so that the pulley starts to rotate synchronously with the pulley B under the cooperation of the belt drivingly connected to it, so that the pulley drives the shaft A fixedly connected to its center to rotate, so that the gear fixedly connected to the shaft A rotates synchronously, so that the two gears start to rotate in opposite directions, so that the shaft A and the shaft A start to rotate in opposite directions, so that the conveyor belts drivingly connected to them start to rotate synchronously in opposite directions, so that the conveyor belts fixedly connected to them rotate synchronously. When the cutter head completes the cutting and starts to rise, the two pressing plates start to contact the PE pipe synchronously and press tightly against the PE pipe, so that the two pressing plates cooperate to push the PE pipe, so that the PE pipe passes through the sleeve A and passes out of the sleeve B. At this time, the pressing plates complete the transportation and move to the reverse side of the conveyor belt to stop feeding. At the same time, the cutter heads descend to cut the PE pipe again to prevent the PE pipe from being damaged due to continuous feeding during the cutting process. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0014] The following will describe in detail the specific implementation of the present utility model in combination with specific embodiments.

[0015] Please refer to Figures 1 to 3 , a fixed-length cutting device for PE water supply pipes provided by an embodiment of the present utility model, including a frame 101, and further including:

[0016] A feeding assembly 2 for intermittent feeding;

[0017] The feeding assembly 2 includes a shaft A 201, a shaft B 202 and a conveyor belt 203. The two shafts A 201 and the two shafts B 202 are symmetrically rotatably connected to the frame 101. The two shafts A 201 cooperate with each other and are drivingly connected to the conveyor belt 203, and the two shafts B 202 cooperate with each other and are drivingly connected to the conveyor belt 203.

[0018] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific shaft A 201 and shaft B 202 recorded in the above embodiment. For example, bearing rings are provided at the connection between the shaft A 201 and shaft B 202 and the frame 101. The purpose of this setting is to facilitate reducing the friction during rotation through this setting, thereby preventing the shaft from breaking after long-term use.

[0019] Specifically, pressure plates 204 are respectively fixedly connected to the two conveyor belts 203, and anti-slip films are provided in the arc holes of the pressure plates 204.

[0020] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific pressure plate 204 recorded in the above embodiment. For example, the anti-slip film in the pressure plate 204 can be replaced with pasting. The purpose of this setting is to facilitate adhering to the PE pipe through the viscosity of pasting, thereby preventing the pressure plate 204 from slipping during the conveying process.

[0021] Specifically, gears 205 are respectively fixedly connected to the shaft A 201 and the shaft B 202, and the two gears 205 are meshingly connected.

[0022] For the above example, those skilled in the art should know that when implementing the above technical solution, it is not limited to the specific gears 205 recorded in the above embodiment. For example, the sizes of the two gears 205 should be the same. The purpose of this setting is to facilitate ensuring that the rotation speeds of the shaft A 201 and the shaft B 202 are the same in this way.

[0023] Specifically, a plurality of sleeve A 206 and sleeve B 207 are fixedly connected to the frame 101, and the sleeve A 206 and the sleeve B 207 are opposite to the arc holes on the pressure plate 204.

[0024] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific casing A206 and casing B207 described in the above embodiments. For example, soft pads may be provided inside the casing B207 and the casing B207. The purpose of this setting is to facilitate providing a buffer for its contact with the PE pipe through the soft pads, thereby preventing scratches from occurring on it.

[0025] Specifically, a pulley 208 is fixedly connected to the shaft A201. The pulley 208 is in transmission connection with a belt 209, and the other end of the belt 209 is in transmission connection with a pulley B301.

[0026] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific pulley 208 and pulley B301 described in the above embodiments. For example, the pulley 208 and the pulley B301 should have pulley grooves with a certain depth. The purpose of this setting is to facilitate limiting the belt 209 in this way, thereby preventing the belt 209 from slipping out during the transmission process.

[0027] Specifically, a wheel shaft 308 is fixedly connected to the center of the pulley B301. The wheel shaft 308 is rotatably connected to the frame 101, and an eccentric wheel 302 is fixedly connected to the wheel shaft 308.

[0028] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific frame 101 described in the above embodiments. For example, universal wheels are provided at the bottom of the frame 101. The purpose of this setting is to facilitate controlling the movement of the device in this way.

[0029] Specifically, a push rod 303 is rotatably connected to the eccentric part of the eccentric wheel 302. The other end of the push rod 303 is hinged to a cutter head 304. The cutter head 304 is slidably connected to the frame 101, and cutter heads 305 are respectively fixedly connected to both sides of the cutter head 304.

[0030] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, it is not limited to the specific cutter head 305 described in the above embodiments. For example, the cutter head 305 should be close to the pipe orifices of the casing A206 and the casing B207. The purpose of this setting is to facilitate preventing the PE pipe from breaking during cutting in this way.

[0031] Specifically, a transmission gear 306 is fixedly connected to the wheel shaft 308. The transmission gear 306 is meshed with a gear fixedly assembled on the output shaft of the motor 307, and the motor 307 is fixedly connected to the frame 101.

[0032] In the embodiment of the present utility model, relevant technicians pass the PE pipe to be cut through between two conveyor belts 203 and pass it out between sleeve A 206 and sleeve B 207. At this time, relevant technicians start the motor 307, so that the axle 308 fixedly connected to the center of the transmission gear 306 starts to rotate, so that the axle 308 drives the eccentric wheel 302 fixedly connected thereto to rotate synchronously, so that the eccentric wheel 302 drives the push rod 303 rotatably connected to its eccentric part to start a circular motion, so that the push rod 303 pushes the cutter head 304 hinged thereto, so that the cutter head 304 starts a linear reciprocating motion along the connection with the frame 101, so as to complete the cutting of the PE pipe through the cutter heads 305 on both sides of the cutter head 304. After the cutting is completed, the cutter head 304 starts to rise; at the same time, when the axle 308 rotates, the pulley B 301 fixedly connected thereto rotates synchronously, so that the pulley 208 starts to rotate synchronously with the pulley B 301 under the cooperation of the belt 209 drivingly connected thereto, so that the pulley 208 drives the axle A 201 fixedly connected to its center to start to rotate, so that the gear 205 fixedly connected to the axle A 201 rotates synchronously, so that the two gears 205 start to rotate in opposite directions, so that the axle A 201 and the axle A 201 start to rotate in opposite directions, so that the conveyor belts 203 drivingly connected thereto start to rotate synchronously in opposite directions, so that the conveyor belts 203 fixedly connected thereto rotate synchronously. When the cutter head 304 completes the cutting and starts to rise, the two pressing plates 204 start to contact the PE pipe synchronously and press tightly against the PE pipe, so that the two pressing plates 204 cooperate to push the PE pipe, so that the PE pipe passes through the sleeve A 206 and passes out of the sleeve B 207. At this time, the pressing plates 204 complete the transportation and move to the reverse side of the conveyor belt 203 to stop feeding. At the same time, the cutter heads 305 descend to cut the PE pipe again to prevent the PE pipe from being damaged due to continuous feeding during the cutting process.

[0033] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0034] The so-called fixed connection in this application means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0035] (1) Detachable connection: Use screws, splines, wedge pins, etc. to fix components together. This connection method can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, and wedge pins), and they must be tightened properly.

[0036] (2) Non-detachable connection: Mainly refers to welding, riveting, and mortise fitting, etc. Since forging, sawing, or oxygen cutting is required to disassemble during maintenance or replacement, the spare parts generally cannot be used a second time. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0037] The sliding connection referred to in this application means that a component can slide along a linear track, and the hinged connection referred to in this application means that a component can rotate along an axial constraint.

[0038] In some cases, the sliding connection and the hinged connection referred to in this application can also be damped, so that the component has the ability to maintain at the desired position.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
