Description

Technical Field

[0001] This utility model relates to the field of PVC plastic pipe technology, and in particular to an automatic feeding device for PVC plastic pipes. Background Technology

[0002] In today's manufacturing industry, automation has become a mainstream development trend. Automation technology can effectively improve production efficiency, reduce production costs, improve product quality, and ensure the stability and safety of the production process. Various industries are actively introducing automated equipment to replace traditional manual operations, and the PVC plastic pipe production industry is no exception. Through automated feeding devices, the feeding process of PVC plastic pipes can be precisely controlled, and the feeding task can be completed quickly and accurately according to preset parameters such as length and quantity, better meeting the requirements of large-scale production and high-precision products. In recent years, with the rapid development of related technical fields such as mechanical manufacturing technology, electronic control technology, sensor technology, and computer programming technology, a solid technical support has been provided for the research and development and application of automatic feeding devices for PVC plastic pipes. High-precision mechanical transmission mechanisms can ensure that the cutting tools move accurately to the designated position for feeding; advanced electronic control systems can easily set and adjust parameters such as feeding length and speed; sensitive sensors can monitor the position and size of the pipes in real time to ensure the accuracy of the feeding process; and computer programming makes the operation of the entire feeding device more intelligent and user-friendly, realizing complex feeding logic and automated process control.

[0003] After the existing equipment finishes cutting, PVC plastic pipes often accumulate, sometimes even around the cutting components, requiring manual cleaning. This significantly increases the workload for workers, and the high intensity of cleaning can cause them to lose focus and slow down their reactions, increasing the risk of accidental injury.

[0004] Therefore, there is an urgent need to provide an automatic PVC plastic pipe feeding device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic feeding device for PVC plastic pipes.

[0006] To solve the above-mentioned technical problems, the present invention provides an automatic PVC plastic pipe feeding device, including a mounting plate. A plurality of connecting blocks are fixedly connected to the top of the mounting plate, and a feeding guide rail is fixedly connected between the tops of the plurality of connecting blocks. Two feeding and unloading components are provided on the top of the mounting plate. A feeding guide rail is fixedly connected to one side of the top of the mounting plate. A cutting component is installed on the top of the mounting plate. A guide plate is fixedly connected to the side of the top of the mounting plate near the feeding guide rail.

[0007] The present invention is further configured such that: the loading and unloading assembly includes two sets of first support rods fixedly connected to the top of the mounting plate; a first connecting plate is fixedly connected to the top of each of the two sets of first support rods; a first hydraulic cylinder is installed on the top of each of the two first connecting plates; a first fixing plate is fixedly connected to the bottom of each of the two first hydraulic cylinders; a mounting box is fixedly connected to the bottom of each of the two first fixing plates; a mounting groove is opened on the bottom of the inner wall of each of the two mounting boxes; two second connecting plates are fixedly connected to the bottom of the inner wall of each of the two mounting boxes; a driven rod is rotatably connected to one side of the front end of each of the two sets of second connecting plates; a motor is installed at the front end of each of the two mounting boxes; a driving rod is fixedly connected to the output end of each of the two motors; each of the two driving rods passes through the corresponding second connecting plate; a driving wheel is fixedly connected to the outer wall of each of the two driving rods; a driven wheel is fixedly connected to the outer wall of each of the two driven rods; multiple sliding grooves are opened on the inner wall of each of the two sets of first support rods; and guide blocks are slidably connected to the inner wall of each of the multiple sliding grooves.

[0008] The above technical solution involves first sliding the PVC plastic pipe to be processed onto the feeding guide rail. Then, the first hydraulic cylinder is activated, causing the first fixed plate to move downwards. Subsequently, the first fixed plate moves the mounting box synchronously, and at the same time, the mounting box moves the drive wheel and driven wheel synchronously until the bottom of the drive wheel and driven wheel contacts the top of the outer wall of the PVC plastic pipe. Then, the motor is activated, causing the motor to rotate the drive rod. Subsequently, the drive rod rotates the drive wheel synchronously, causing the PVC plastic pipe to move towards the feeding guide rail. The driven wheel moves synchronously due to the friction between itself and the PVC plastic pipe.

[0009] The present invention is further configured such that the front and rear ends of the two driving rods and driven wheels are tightly fitted with the inner wall of the corresponding second connecting plate.

[0010] The above technical solution enables the driving rod to accurately transmit power to the driven wheel during rotation. The driven wheel then drives the subsequent components to operate according to the designed transmission ratio and other parameters, thus avoiding cutting errors caused by transmission deviations.

[0011] The present invention is further configured such that: each group of guide blocks has an installation box fixedly connected between its inner walls, and the multiple guide blocks are matched with corresponding slide grooves.

[0012] The above technical solution ensures that the material always travels along the predetermined path, avoiding deviation or misalignment, thus guaranteeing the accuracy of feeding and improving the cutting quality.

[0013] The present invention is further configured such that the top of each first support rod is integrally integrated with the bottom of the corresponding first connecting plate.

[0014] Through the above technical solutions, it can function as a robust whole, effectively avoiding structural instability caused by loose or broken connections. Furthermore, this integrated design makes the entire structure more stable and reliable, ensuring the equipment operates stably for a long time.

[0015] The present invention is further configured such that: the cutting assembly includes two second support rods fixedly connected to the top of the mounting plate, a third connecting plate fixedly connected between the tops of the two second support rods, a second hydraulic cylinder installed on the top of the third connecting plate, a second fixing plate fixedly connected to the bottom of the second hydraulic cylinder, and a cutting machine installed on the bottom of the second fixing plate.

[0016] Using the above technical solution, the PVC plastic pipe first passes directly below the cutting machine until one side of the PVC plastic pipe moves onto the feeding guide rail. At this point, the required cutting dimensions are measured, and the cutting machine is started. At the same time, the second hydraulic cylinder is activated, causing the second hydraulic cylinder to drive the third connecting plate downwards. Subsequently, the third connecting plate drives the cutting machine to move synchronously until the cutting machine completes the cutting of the PVC plastic pipe.

[0017] The present invention is further configured such that the cutting machine is positioned at the exact center of the feeding guide rail and the unloading guide rail.

[0018] With the above technical solution, when cutting PVC plastic pipes conveyed along the guide rail, the supporting force from the guide rail on both sides of the pipe is more uniform, and the pipe shaking or shifting during the cutting process is avoided due to uneven force, resulting in a smoother cut surface and improved product quality.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting up loading and unloading components, this utility model can automatically and orderly transport the pipes to be cut to the cutting station. After cutting, the unloading component will accurately transfer the processed pipes away. The whole process does not require frequent manual intervention. Each link works closely together and operates automatically and continuously, which greatly improves the continuity of production, effectively shortens the processing cycle of a single pipe, and thus improves the overall production efficiency.

[0021] 2. This utility model uses a cutting component that can immediately start the cutting program when the pipe is transported to the predetermined position. After the cutting is completed, it can promptly notify the unloading component to pick up the finished pipe. The whole process is seamlessly connected, realizing automated continuous production operations, avoiding time waste between each link, and further improving the overall efficiency of the production process.

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0029] Please see Figure 1-Figure 5An automatic PVC plastic pipe feeding device includes a mounting plate 1. Multiple connecting blocks 2 are fixedly connected to the top of the mounting plate 1. Feeding guide rails 3 are fixedly connected between the tops of the multiple connecting blocks 2. Two feeding / unloading assemblies 4 are provided on the top of the mounting plate 1. Each feeding / unloading assembly 4 includes two sets of first support rods 401 fixedly connected to the top of the mounting plate 1. A first connecting plate 402 is fixedly connected to the top of each of the two sets of first support rods 401. A first hydraulic cylinder 403 is mounted on the top of each of the two first connecting plates 402. A first fixing plate 404 is fixedly connected to the bottom of each of the two first fixing plates 404. An installation box 405 is fixedly connected to the bottom of each of the two installation boxes 405. An installation groove 406 is formed on the bottom of the inner wall of each of the two installation boxes 405. Two second connecting plates 407 are fixedly connected to the bottom of each inner wall. A driven rod 408 is rotatably connected to one side of the front end of each of the two sets of second connecting plates 407. Motors 409 are installed at the front ends of each of the two mounting boxes 405. A driving rod 4010 is fixedly connected to the output end of each of the two motors 409. Each driving rod 4010 passes through a corresponding second connecting plate 407. A driving wheel 4011 is fixedly connected to the outer wall of each of the two driving rods 4010. A driven wheel 4012 is fixedly connected to the outer wall of each of the two driven rods 408. Multiple sliding grooves 4013 are opened on the inner wall of each of the two sets of first support rods 401. Guide blocks 4014 are slidably connected to the inner wall of each of the multiple sliding grooves 4013. First, the PVC plastic pipe to be processed is slidably connected into the feeding guide rail 3, and then the first... Hydraulic cylinder 403 causes the first fixed plate 404 to move downwards. The first fixed plate 404 then drives the mounting box 405 to move synchronously. Simultaneously, the mounting box 405 drives the drive wheel 4011 and driven wheel 4012 to move synchronously until the bottoms of the drive wheel 4011 and driven wheel 4012 contact the top of the outer wall of the PVC plastic pipe. Then, motor 409 is started, causing the drive rod 4010 to rotate. The drive rod 4010 then drives the drive wheel 4011 to rotate synchronously, causing the PVC plastic pipe to move towards the feeding guide rail 3. The driven wheel 4012 moves synchronously due to friction with the PVC plastic pipe. The two drive rods 4010 and driven wheel 4012... Both ends of the driving wheel 4012 are tightly fitted to the inner wall of the corresponding second connecting plate 407, so that the driving rod 4010 can accurately transmit power to the driven wheel 4012 during rotation. The driven wheel 4012 then drives the subsequent components to operate according to the designed transmission ratio and other parameters, avoiding cutting errors caused by transmission deviation. Each set of guide blocks 4014 has a mounting box 405 fixedly connected to the inner wall, and multiple guide blocks 4014 are matched with the corresponding slide groove 4013, which can ensure that it always travels along the predetermined path and avoids deviation, misalignment, etc., thereby ensuring the accuracy of feeding and improving the cutting quality. The top of each set of first support rods 401 is an integral structure with the bottom of the corresponding first connecting plate 402.It can function as a robust whole, effectively preventing structural instability caused by loose or broken connections. This integrated design makes the entire structure more stable and reliable, ensuring long-term stable operation of the equipment.

[0030] like Figure 2 and Figure 4 As shown, a feeding guide rail 5 is fixedly connected to one side of the top of the mounting plate 1. A cutting assembly 6 is installed on the top of the mounting plate 1. The cutting assembly 6 includes two second support rods 601 fixedly connected to the top of the mounting plate 1. A third connecting plate 602 is fixedly connected between the tops of the two second support rods 601. A second hydraulic cylinder 603 is installed on the top of the third connecting plate 602. A second fixing plate 604 is fixedly connected to the bottom of the second hydraulic cylinder 603. A cutting machine 605 is installed on the bottom of the second fixing plate 604. First, the PVC plastic pipe will pass directly under the cutting machine 605 until one side of the PVC plastic pipe moves onto the feeding guide rail 5. At this time, the size to be cut is measured, and then the cutting machine 605 is started. At the same time, the second hydraulic cylinder 603 is started, so that the second hydraulic cylinder 603 drives the third connecting plate 602 to move downward. Then the third connecting plate 602 will drive the cutting machine 605 to move synchronously until the cutting machine 605 cuts the PVC plastic pipe. The cutting machine 605 is set at the center of the feeding guide rail 3 and the feeding guide rail 5. The PVC plastic pipe is conveyed along the guide rail. When the plastic pipe is cut, the support force from the guide rail on both sides of the pipe is more uniform, and the pipe is prevented from shaking or shifting during the cutting process due to uneven force. This makes the cut surface flatter and improves product quality. A guide plate 7 is fixedly connected to the top of the mounting plate 1 near the feeding guide rail 5.

[0031] In use, the PVC plastic pipe to be processed is first slidably connected to the feeding guide rail 3. Then, the first hydraulic cylinder 403 is activated, causing the first fixed plate 404 to move downwards. Subsequently, the first fixed plate 404 drives the mounting box 405 to move synchronously. At the same time, the mounting box 405 drives the driving wheel 4011 and the driven wheel 4012 to move synchronously until the bottom of the driving wheel 4011 and the driven wheel 4012 contact the top of the outer wall of the PVC plastic pipe. Then, the motor 409 is activated, causing the motor 409 to drive the driving rod 4010 to rotate. Subsequently, the driving rod 4010 drives the driving wheel 4011 to rotate synchronously, causing the PVC plastic pipe to move towards the feeding guide rail 3. The driven wheel 4012 moves synchronously with the PVC plastic pipe through friction. The PVC plastic pipe passes directly under the cutting machine 605 until one side of the PVC plastic pipe moves onto the feeding guide rail 5. At this time, the required cutting size is measured, and the cutting machine 605 is started again. At the same time, the second hydraulic cylinder 603 is started, which drives the third connecting plate 602 to move downward. Then, the third connecting plate 602 drives the cutting machine 605 to move synchronously until the cutting machine 605 finishes cutting the PVC plastic pipe. Then, the loading and unloading assembly 4 continuously pushes the PVC plastic pipe to one side, so that the cut PVC plastic pipe will move along the feeding guide rail 5 to the guide plate 7.
