[0001] The present application relates to the field of plastic pipe production equipment, and in particular to a plastic pipe production guiding and positioning device. Background Art

[0002] In the plastic pipe production process, the plastic pipe is extruded and formed through an extruder, and is cooled, cut and processed by a traction device. On the plastic pipe production line, the plastic pipe needs to be conveyed in a directional manner so that it can accurately enter the designated device for processing. The accuracy and efficiency of the plastic pipe guiding and positioning technology have an important impact on product quality and production efficiency.

[0003] Traditional guiding and positioning devices usually adopt mechanical structures, and realize the guiding and positioning of plastic pipes by manual adjustment or fixed position. This method is not only complicated to operate, but also has low positioning accuracy and stability, which cannot meet the production requirements of high precision and high efficiency, is time-consuming and labor-intensive, and is not conducive to improving production efficiency. Utility Model Content

[0004] In order to improve the production efficiency of plastic pipes, the present application provides a plastic pipe production guiding and positioning device.

[0005] The present application provides a plastic pipe production guide and positioning device, which adopts the following technical solution:

[0009] By adopting the above technical solution, the base provides stable support for the entire device, ensuring the stability of the device during the production process. The guide mechanism can effectively guide the movement direction of the plastic pipe, ensuring that the plastic pipe can move accurately along the predetermined path. The positioning mechanism works closely with the guide mechanism to accurately position the plastic pipe, thereby ensuring the position accuracy of the plastic pipe during the production process, improving the guiding and positioning effects of the plastic pipe, and thus improving the production efficiency of the plastic pipe.

[0010] Optionally, the guide mechanism includes a guide sleeve and a guide wheel, the guide sleeve is arranged on the outside of the plastic tube, and the guide wheel is arranged inside the guide sleeve.

[0011] By adopting the above technical solution, the guide sleeve is arranged outside the plastic pipe to perform preliminary positioning and guidance on the plastic pipe. The guide wheel is arranged inside the guide sleeve, which can further ensure the stability and smoothness of the plastic pipe during movement and prevent the plastic pipe from deflecting or jamming during movement.

[0012] Optionally, the positioning mechanism includes a positioning sensor and a positioning clamp, the positioning sensor is arranged on one side of the guide mechanism to detect position information of the plastic pipe, and the positioning clamp clamps and positions the plastic pipe according to a signal from the positioning sensor.

[0013] By adopting the above technical solution, the positioning sensor can monitor the position information of the plastic pipe in real time and transmit this information to the positioning clamp. The positioning clamp can quickly and accurately clamp and position the plastic pipe according to the received position information, thereby ensuring the position accuracy of the plastic pipe during the production process.

[0014] Optionally, the positioning clamp comprises a driving component and a positioning component, the positioning component slides with the guide sleeve, and the driving component drives the positioning component to perform a positioning action on the plastic pipe.

[0015] By adopting the above technical solution, the driving component can provide stable power output for the positioning component, ensuring that the positioning component can stably perform the positioning action. This structural design enables the positioning clamp to achieve stable and reliable positioning effects when facing plastic pipes of different sizes and weights.

[0016] Optionally, the positioning component includes a plurality of positioning members, which are arranged to form a positioning space for positioning the plastic pipe. The positioning member slides with the guide sleeve via a driving component, and a first ball is provided at a positioning end of the positioning member.

[0017] By adopting the above technical solution, multiple positioning members can be driven by the driving component to move toward the center at the same time, so as to stably and reliably position the plastic pipe. This structural design not only improves the stability and reliability of positioning, but also enables the device to adapt to plastic pipes of different sizes. When clamping and positioning the plastic pipe, the first ball contacts the plastic pipe, so that the plastic pipe can be transported while being clamped and positioned, reducing the friction force during the transportation of the plastic pipe and improving the smoothness of the transportation of the plastic pipe.

[0018] Optionally, the positioning member is connected to a restraining member, the restraining member slides with the guide sleeve, the restraining member is located in the guide sleeve, and a second ball is provided at one end of the restraining member away from the guide sleeve.

[0019] By adopting the above technical solution, the positioning member slides on the guide sleeve, and the sliding of the positioning member drives the constraint member to slide in the guide sleeve. When the first ball contacts the plastic tube, as the plastic tube is transported, the plastic tube contacts the second ball, and the conveying direction of the plastic tube in the guide sleeve is constrained, so that the plastic tube is transported in a directional manner, the possibility of deviation of the conveying direction of the plastic tube is reduced, and the guiding and positioning effects of the plastic tube are improved.

[0020] Optionally, the positioning sensor is a photoelectric sensor or a proximity sensor.

[0021] By adopting the above technical solution, both the photoelectric sensor and the proximity sensor have high detection accuracy and response speed, which can ensure the accuracy and timeliness of the positioning sensor in detecting the position information of the plastic pipe, so that the positioning mechanism can still maintain stable positioning performance when facing high-speed moving plastic pipes.

[0022] Optionally, a control system is also included, which is electrically connected to the positioning mechanism and is used to control the action of the positioning mechanism.

[0023] By adopting the above technical solution and introducing a control system, intelligent control of the positioning mechanism can be achieved.

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The embodiment of the present application discloses a plastic pipe production guiding and positioning device.

[0036] Reference Figure 1 A plastic pipe production guiding and positioning device comprises a base 1, a guiding mechanism 2 and a positioning mechanism 3. The top wall of the base 1 is fixed to the guiding mechanism 2. The guiding mechanism 2 is used to guide the movement direction of the plastic pipe so that the plastic pipe can move stably along a predetermined path. The positioning mechanism 3 is connected to the guiding mechanism 2 and is used to accurately position the plastic pipe to meet the requirements of the subsequent production process for position accuracy, so that the plastic pipe can move in a directional manner during the production process, reduce the possibility of manual adjustment of the plastic pipe due to the deviation of the plastic pipe, and improve the production efficiency of the plastic pipe.

[0037] In addition, this embodiment also includes a control system, which is electrically connected to the positioning mechanism 3 and is used to control the action of the positioning mechanism 3, perform intelligent control on the positioning mechanism 3, and adjust the action of the positioning mechanism 3 in real time, thereby improving the positioning accuracy of the plastic pipe during transportation and further improving the production efficiency of the plastic pipe.

[0038] Specifically, refer to Figure 2 The guide mechanism 2 includes a guide sleeve 21 and a guide wheel 22. The bottom wall of the guide sleeve 21 is fixed to the top wall of the base 1. The guide sleeve 21 is provided with a conveying path 211. The plastic pipe is conveyed into the conveying path 211, so that the guide sleeve 21 is sleeved on the outside of the plastic pipe to guide the conveying direction of the plastic pipe, and to support and protect the plastic pipe. The guide wheel 22 is arranged inside the guide sleeve 21 and is located at the bottom of the guide sleeve 21. The guide wheel 22 is rotatably connected to the guide sleeve 21. After the plastic pipe conveys the guide sleeve 21, the plastic pipe is conveyed to the top of the guide wheel 22, and the pipe wall of the plastic pipe contacts the side wall of the guide wheel 22. Under the traction of the traction device, when the plastic pipe moves on the guide wheel 22, the guide wheel 22 is driven to rotate. The plastic pipe guides the movement direction of the plastic pipe through the rolling of the guide wheel 22, reduces the friction resistance of the plastic pipe during the movement, and improves the smoothness and accuracy of the plastic pipe guidance.

[0039] In this embodiment, the guide wheel 22 is composed of two rollers 221 and a rotating roller shaft 222. The rollers 221 and the rotating roller shaft 222 are fixed to each other. The rotating roller shaft 222 is rotatably connected to the guide sleeve 21. When the plastic pipe is transported, the plastic pipe is mounted between the two rollers 221. The plastic pipe is tangent to the rollers 221 to form point contact. Plastic pipes of various specifications can be transported, thereby improving the applicability of the guide wheel 22.

[0040] Reference Figure 1 The positioning mechanism 3 includes a positioning sensor 31 and a positioning clamp 32. The positioning sensor 31 is installed at one end of the guide sleeve 21 and is used to detect the position information of the plastic pipe in real time. The positioning clamp 32 is electrically connected to the positioning sensor 31. The positioning clamp 32 clamps and positions the plastic pipe according to the signal of the positioning sensor 31 to ensure that the plastic pipe can stay stably at a predetermined position.

[0041] The positioning clamp 32 includes a driving component and a positioning component. The driving component is electrically connected to the control system. The driving component is responsible for providing power to drive the positioning component to perform the positioning action. The positioning components are symmetrically arranged at both ends of the guide sleeve 21 to improve the accuracy of the conveying direction of the plastic pipe.

[0042] The conveying path 211 is circular, referring to Figure 3 and Figure 4The two ends of the guide sleeve 21 are symmetrically fixedly connected with clamping frames 321, which are arranged equidistantly along the conveying path 211 and are respectively located on the transverse axis or the vertical axis. The positioning component includes a plurality of positioning members 322, which are surrounded by a positioning space for positioning the plastic pipe. The positioning space surrounded by the positioning members 322 is located in the extension direction of the conveying path 211. The positioning members 322 are inserted in the clamping frames 321 and are slidably connected with the clamping frames 321. The positioning members 322 are arranged equidistantly along the conveying path 211. The center of the delivery path 211 is located in the sliding direction of the positioning piece 322. The driving component is electrically connected to the positioning sensor 31. The positioning sensor 31 is used to sense the position of the plastic pipe and transmit a signal to the driving component to clamp or release the plastic pipe. The positioning piece 322 slides with the guide sleeve 21 through the driving component. The end of the positioning piece 322 facing the positioning space direction is the positioning end of the positioning piece 322. The positioning end of the positioning piece 322 is provided with a first ball 323, and the first ball 323 is rollingly connected to the positioning piece 322.

[0043] When clamping and positioning the plastic tube, the plastic tube passes through the positioning space formed by the positioning piece 322, the positioning sensor 31 senses the plastic tube, and transmits a clamping signal to the driving component at the same time. The driving component drives the positioning piece 322 to clamp and position the plastic tube, and all the positioning pieces 322 slide toward the plastic tube at the same time until the first ball 323 contacts the plastic tube. The positioning piece 322 slides the same distance on the guide sleeve 21 to constrain and position the conveying direction of the plastic tube. The plastic tube passes through the positioning space formed by the clamping piece and is continuously conveyed through the conveying path 211.

[0044] In this embodiment, the driving component adopts an air pump. Specifically, the clamping frame 321 is provided with a sliding cavity 324, and the end of the positioning member 322 away from the first ball 323 is inserted into the sliding cavity 324. The guide sleeve 21 is provided with an air inlet and outlet 325 connected to the sliding cavity 324. The air pump is started to inflate the sliding cavity 324 through the air inlet and outlet 325. The air pressure in the sliding cavity 324 is greater than the external environmental atmospheric pressure. The gas pushes the positioning member 322 to slide from the center of the conveying path 211 to clamp and position the plastic tube. When the plastic tube needs to be pulled out from the positioning space, the air pump is started to pull out the gas in the sliding cavity 324 through the air inlet and outlet 325. The air pressure in the sliding cavity 324 is less than the external environmental atmospheric pressure. The positioning member 322 slides to the end away from the center of the conveying path 211, so that the positioning space is open and the plastic tube can be pulled out from the positioning space.

[0045] The laterally arranged positioning piece 322 is fixedly connected with the restraining piece 5, and the two ends of the restraining piece 5 are respectively connected with the positioning pieces 322 symmetrically arranged at the two ends of the guide sleeve 21, the restraining piece 5 slides with the guide sleeve 21, the restraining piece 5 is located in the conveying path 211 of the guide sleeve 21, and the end of the restraining piece 5 away from the guide sleeve 21 is rollingly connected with the second ball 51.

[0046] The first ball 323 guides the plastic pipe to enter the conveying path 211, so that the plastic pipe can enter the conveying path 211 smoothly. When the positioning member 322 slides on the guide sleeve 21, the sliding of the positioning member 322 drives the constraint member 5 to slide in the guide sleeve 21, so that the second ball 51 contacts the plastic pipe. The second ball 51 clamps and positions the pipe on both sides of the sliding direction of the plastic pipe, constrains the conveying direction of the plastic pipe in the guide sleeve 21, and conveys the plastic pipe in a directional manner, further reducing the possibility of deviation of the conveying direction of the plastic pipe, and improving the guiding and positioning effect of the plastic pipe.

[0047] Reference Figure 1 The positioning sensor 31 can be a photoelectric sensor or a proximity sensor. These sensors have the characteristics of high sensitivity and high precision. They can monitor the movement information and existence information of the plastic pipe in real time and convert the information into electrical signals and transmit them to the control system. The control system then controls the driving component to drive. When the first ball 323 is against the wall of the plastic pipe, the driving component stops driving the positioning member 322 to move, which can further improve the accuracy and reliability of positioning.

[0048] The control system includes a controller 4, which is electrically connected to the driving component, and the controller 4 is electrically connected to the positioning sensor 31, and controls the positioning member 322 to perform a clamping positioning or releasing action on the plastic pipe through a signal of the positioning sensor. Through the precise control of the controller 4, it can be ensured that the positioning jaws 32 perform a clamping positioning or releasing operation on the plastic pipe at the best time, thereby improving the positioning accuracy and response speed of the entire device.

[0049] During the implementation process, after receiving the position signal sent by the positioning sensor 31, the controller 4 determines whether the plastic tube has reached the predetermined positioning position according to the preset logic. When it is determined that the plastic tube has reached the positioning position, the controller 4 sends a command to the driving component to drive the positioning member 322 to clamp and position the plastic tube. When the plastic tube needs to be released, the controller 4 sends a command to the driving component again to make the positioning member 322 release the plastic tube.

[0050] The implementation principle of this embodiment is as follows: the positioning sensor 31 monitors the position information of the plastic pipe in real time and transmits it to the controller 4. The plastic pipe passes through the positioning space of the positioning member 322. The controller 4 transmits the positioning sensor 31 to the driving component. The driving component drives the positioning member 322 to move toward the plastic pipe until the first ball 323 abuts against the pipe wall of the plastic pipe. The positioning clamp 32 realizes the clamping and positioning of the plastic pipe. Under the continuous traction of the traction device, the plastic pipe is continuously transported. The first ball 323 rolls with the plastic pipe, and the plastic pipe enters the conveying path 211 in a directional manner to reduce the possibility of the plastic pipe being offset. The plastic pipe enters the guide sleeve 21. The plastic pipe is mounted on the top of the guide wheel 22 and contacts the second ball 51. The conveying direction of the plastic pipe in the guide sleeve 21 is restricted, so that the plastic pipe is smoothly output at the other end of the guide sleeve 21, and the precise guiding, positioning and conveying of the plastic pipe is realized, thereby ensuring the precise positioning and efficient operation of the plastic pipe in the production process and improving the production efficiency of the plastic pipe.
