Abstract
Description
Technical Field
[0001] This utility model relates to the field of PPR pipe fitting production and packaging technology, and in particular to a marking chain conveyor anti-vibration device for all-plastic elbow tee pipe fittings. Background Technology
[0002] In the automated production and packaging process of PPR pipe fittings, all-plastic elbows and tees require a gripping robot to pick up the fittings in a fixed posture and place them onto a carrier on a chain conveyor. Simultaneously, the chain conveyor transports the fittings while a laser marking machine laser-marks anti-counterfeiting QR codes. After marking, a barcode scanner scans the codes and uploads them to the system for subsequent information binding. However, due to vibrations during product transport on the chain conveyor, the QR codes may be distorted during laser marking. These distorted QR codes cannot be recognized by the scanner and are thus rejected as waste, resulting in economic losses. Therefore, a device is needed to reduce vibrations during product transport on the chain conveyor. Utility Model Content
[0003] To address the aforementioned problems, this utility model aims to provide an anti-vibration device for marking chain conveyor belts on all-plastic elbow tee fittings, thereby solving the vibration problem during product conveying on chain conveyors.
[0004] The technical problem solved by this utility model can be achieved by the following technical solution: A chain conveyor anti-vibration device for marking all-plastic elbow tee pipe fittings includes a chain conveyor, an anti-vibration pressure plate mechanism, an adjustable pipe fitting limit frame, and a laser marking machine. The inlet end of the chain conveyor is equipped with a photoelectric sensor. The anti-vibration pressure plate mechanism is located at the laser marking point on the chain conveyor. Anti-vibration pressure plate mechanisms are respectively located on both sides of the chain conveyor. The lower part of the anti-vibration pressure plate mechanism is fixed to the chain conveyor, and the upper part presses against the edge of the chain conveyor. An adjustable pipe fitting limit frame is located on one side of the chain conveyor, and the lower end of the adjustable pipe fitting limit frame is fixed to the chain conveyor. The laser marking machine is located above the chain conveyor belt and is mounted on an adjustable support.

[0019] Combined with appendix Figures 1 to 5 As shown, this embodiment discloses a vibration-proof device for marking chain conveyor belts of all-plastic elbow tee pipe fittings, including a chain conveyor 1, a vibration-proof pressure plate mechanism 2, an adjustable pipe fitting limit frame 5, a laser marking machine 4, and an adjustable support 3 for the laser marking machine. The inlet end of the conveyor chain of the chain conveyor 1 is equipped with a photoelectric sensor. Vibration-proof pressure plate mechanisms 2 are respectively installed on both sides of the conveyor chain. The lower part of the vibration-proof pressure plate mechanism 2 is fixed to the chain conveyor 1, and the upper part of the vibration-proof pressure plate mechanism 2 presses against the edge of the conveyor chain. An adjustable pipe fitting limit frame 5 is installed on one side of the conveyor chain, and the lower end of the adjustable pipe fitting limit frame 5 is fixed to the chain conveyor 1. The laser marking machine 4 is located above the chain conveyor belt and is mounted on the adjustable support 5 for the laser marking machine.
[0020] The anti-vibration pressure plate mechanism 2 is installed at the laser marking point of the laser marking machine 4 on the conveyor chain. The anti-vibration pressure plate mechanism 2 includes a fixed plate mounting frame 11, a pressure block fixing plate 10, a pressure block 15, and a buffer layer 16. The fixed plate mounting frame 11 is fixed to the side of the conveyor chain 1. The pressure block fixing plate 10 is fixedly installed on the fixed plate mounting frame 11, and the pressure block 15 is fixedly installed on the pressure block fixing plate 10. The pressure block 15 presses against the side edge of the conveyor chain. A buffer layer 16 is provided between the pressure block fixing plate 10 and the pressure block 15. The conveyor chain of the conveyor chain 1 in the marking section is limited by the pressure blocks 15 on both sides, preventing vibration of the conveyor chain at this point. This ensures that the laser QR code marking is not deformed, allowing it to be easily scanned and identified by the rear-end scanner and uploaded to the system for information binding.
[0021] The fixed plate mounting bracket 11 is connected and fixed to the chain conveyor 1 by four hexagon socket screws. The pressure block fixing plate 10 is connected and fixed to the fixed plate mounting bracket 11 by four hexagon socket screws. The pressure block 15 is connected and fixed to the pressure block fixing plate 10 by four hexagon socket screws and nuts. The pressure block 15 is made of polytetrafluoroethylene (PTFE), which has good self-lubricating properties, reducing friction between it and the conveyor chain and improving the stability of the conveyor. A buffer layer 16 is set between the pressure block fixing plate 10 and the PTFE pressure block 15 to provide cushioning for the PTFE pressure block 15. The buffer layer 16 is made of polyurethane, which has a certain degree of flexibility, allowing the PTFE pressure block 15 to float in the vertical direction, preventing it from crushing the conveyor chain of the chain conveyor 1 and causing an overload alarm on the conveyor motor.
[0022] The photoelectric sensor includes a photoelectric sensor transmitter 8 and a photoelectric sensor receiver 7, which are symmetrically arranged on both sides of the conveyor chain. The photoelectric sensor transmitter 8 is fixed on a photoelectric sensor transmitter mounting bracket 9, and the photoelectric sensor receiver 7 is fixed on a photoelectric sensor receiver mounting bracket 6. The photoelectric sensor transmitter mounting bracket 9 is fixed on a pressure block fixing plate 10 on one side of the chain conveyor 1, and the photoelectric sensor receiver mounting bracket 6 is fixed on a pressure block fixing plate 10 on the other side of the chain conveyor 1. The photoelectric sensor transmitter and the photoelectric sensor receiver are combined to sense the pipe fittings, thereby triggering the marking action of the laser marking machine 4.
[0023] The adjustable pipe fitting limiting frame 5 includes multiple adjustable clamps, multiple adjustable clamp seats, and a stainless steel limiting abutment rod. The adjustable clamp seats are fixed to the side of the chain conveyor 1, and each adjustable clamp seat is equipped with an adjustable clamp. The limiting abutment rod is fixed to the adjustable clamps and is located on the upper side of the chain conveyor line. The adjustable clamp seats can adjust the vertical position of the limiting abutment rod, and the adjustable clamps can adjust the front-to-back position of the limiting abutment rod. The adjustable pipe fitting limiting frame 5 can adjust the vertical and front-to-back positions of the limiting abutment rod, thus accommodating the limiting abutment of different specifications and types of all-plastic tee elbow pipe fittings.
[0024] The chain conveyor 1 has multiple carriers 12 evenly arranged on the conveyor chain line. Each carrier 12 is connected and fixed to a chain plate by two hexagonal screws. All-plastic tee fittings 13 or all-plastic elbow fittings 14 can be placed on the carriers 12.
[0025] The laser marking machine 4 is mounted on the adjustable support 3. The adjustable support 3 is designed to be adjustable, which can be used to adjust the up and down and front and back positions of the laser marking machine, so as to be compatible with marking of different specifications and types of all-plastic tee elbow pipe fittings.
[0026] The specific implementation process of this utility model device in the production process is as follows: First, adjust the up-down and back-forward positions of the stainless steel limiting rod on the adjustable pipe fitting limit frame 5 according to the product type and size specifications to be produced and packaged. At the same time, adjust the up-down and back-forward positions of the laser marking machine 4 using the adjustable bracket 3 of the laser marking machine. Then, start the device. The chain conveyor 1 drives the upper carrier 12 to continuously transport to the right. Simultaneously, the front-end loading robot continuously grabs the all-plastic elbow pipe fitting 14 or all-plastic tee pipe fitting 13 and places them on the carrier 12 on the left side of the chain conveyor 1. The chain conveyor 1 drives the carrier 12 and the pipe fittings placed on it to continuously move to the right. During this process, the adjustable pipe fitting limit frame 5 guides and limits the pipe fittings to prevent the orientation of the pipe fittings from changing during transportation, ensuring the uniformity of the subsequent laser QR code position. When the transported pipe fitting is detected by the photoelectric sensor, the laser marking machine 4 triggers laser marking to engrave the anti-counterfeiting QR code on the upper surface of the pipe fitting. During the marking process, the conveyor chain of the chain conveyor 1 in the marking section is limited by the polytetrafluoroethylene pressure blocks 15 on both the front and rear sides, preventing vibration of the conveyor chain at this point. This ensures that the laser QR code marking is not deformed and can be easily scanned and identified by the rear-end scanner, uploaded to the system for information binding. At the same time, the polyurethane buffer layer 16 allows the pressure blocks 15 to float vertically, preventing them from crushing the conveyor chain and causing an overload alarm on the conveyor motor. As the pipe fittings are continuously moved to the right by the chain conveyor 1 and are continuously triggered by the photoelectric sensor to mark the laser marking machine 4, the pressure blocks 15 on both the front and rear sides of the conveyor chain continuously limit and prevent vibration of the conveyor chain. This process is repeated until the device completes its operation.
[0027] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
