Description

Technical Field

[0001] The invention belongs to the technical field of plate feeding, and in particular relates to a plate feeding device used in furniture and sanitary ware manufacturing and production. Background Art

[0002] Furniture and bathroom refer to the furniture and bathroom equipment in homes or commercial places; furniture and bathroom are an important part of interior design and decoration, and their material selection, style and layout will affect the comfort and aesthetics of the living environment; in the manufacturing process of furniture and bathroom, a large number of panels are needed, and in order to meet production needs, the panels often need to be cut, and a series of cutting processes require the use of feeding devices for coordinated production.

[0003] In the actual feeding of plates, due to the different materials of various plates, the use of a fixed conveying force will affect the feeding stability of the plates. For plates with lighter materials, the material is relatively softer, resulting in limited compressive resistance of the plates themselves. When a relatively large conveying force is used [the conveying force refers to the force used to push the plates forward in the plate feeding device], the plates are prone to deformation when subjected to greater pressure [according to Newton's third law, the action force and reaction force are equal in magnitude and opposite in direction. When the conveying roller is subjected to the force of the transmission device, it will generate a reaction force on the plates. This reaction force is the pressure of the conveying roller on the plates. Therefore, the greater the conveying force, the greater the pressure of the conveying roller on the plates]. Conversely, for heavier plates, insufficient conveying force will affect the stable transportation of the plates, resulting in the problem of plates slipping during transportation.

The air blowing cleaning mechanism can be set up to blow and clean the chain when the conveyor is working, so as to reduce the dust and impurities carried on the chain, thereby avoiding the problem that the presence of dust will increase the friction between the chain and the sprocket, thereby causing the chain to wear more severely, and avoiding the impurities on the chain to affect the adhesion and distribution of the lubricant, thereby reducing the lubrication effect. The greater the tension of the chain, the smaller the blowing force on the chain, thereby avoiding the connection structure on the chain being relatively more separated due to the increase in the tension of the chain. Excessive wind force will make the lubricant on the surface of the chain easier to be blown away, thereby causing the problem of aggravated chain wear. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The lubrication trigger mechanism 7 is fixedly mounted at the lower end of the conveyor 1 and is connected to the air blast cleaning mechanism 6. The lubrication trigger mechanism 7 includes a trigger shell 71 fixedly mounted at the lower end of the conveyor 1. The internal sealing sleeve of the trigger shell 71 is provided with a movable piston 72. The side wall of the movable piston 72 is fixedly connected with a plurality of limit slide bars 73. The end of the limit slide bar 73 away from the movable piston 72 extends out of the trigger shell 71. A plurality of pressure springs 74 sleeved on the outside of the limit slide bar 73 are fixedly connected between the movable piston 72 and the trigger shell 71. A trigger switch 75 arranged opposite to the movable piston 72 is fixedly mounted on the inner wall of the trigger shell 71. The air supply pipe 62 and the trigger shell 71 are fixedly connected with the same branch pipe 76. A proportional solenoid valve 77 is mounted on the branch pipe 76. A pressure relief pipe 78 is also fixedly connected to the side wall of the trigger shell 71. An on-off valve 79 is mounted on the pressure relief pipe 78.

[0025] The PLC controller 10 is fixedly mounted on the outer wall of the conveyor 1 and is electrically connected to the auxiliary pushing mechanism 2, the plate weight detection feedback mechanism 3, the conveying force regulating mechanism 4, the automatic lubrication mechanism 5, the air blast cleaning mechanism 6 and the lubrication trigger mechanism 7 respectively.

[0026] The operating principle of the present invention is described as follows: the plate to be fed is placed on the guide table 8, the PLC controller 10 controls the electric slide rail 21 to move, the electric slide rail 21 drives the push block 23 to move through the U-shaped push-pull plate 22, and then the plate slides on the universal ball 9 on the guide table 8, so that the plate enters the conveyor 1 for rapid feeding; When the push block 23 pushes the plate to move, it needs to overcome the gravity of the plate based on the friction resistance between the plate and the conveying surface. The heavier the plate, the greater the thrust required, so that the push block 23 cooperates with the compensation rod 32 to overcome the elastic force of the compensation spring 34 and moves a greater distance toward the feedback shell 31. The feedback plate 33 connected at one end of the compensation rod 32 located in the feedback shell 31 pushes the sliding plate 36 to move along the friction rod 35. Because the friction rod 35 and the resistance cylinder 37 cooperate, the sliding plate 36 can accurately move the same distance based on the moving distance of the feedback plate 33. The sliding plate 36 drives the feedback conductive contact 311 to move on the feedback resistor rod 310. Specifically, the heavier the plate, the greater the distance the feedback plate 33 pushes the sliding plate 36 to move, so that the feedback conductive contact 311 slides on the feedback resistor rod 310. The access resistance value of the feedback resistor rod 310 is smaller. The feedback conductive contact 311 and the feedback resistor rod 310 are connected in series to the power supply circuit of the regulating electromagnetic plate 47. When the regulating electromagnetic plate 47 is energized, it generates the same magnetism as the regulating permanent magnet plate 46, thereby pushing the force-bearing plate 42 and the tensioning wheel 43 to overcome the elastic force of the push spring 45 and move downward, thereby tightening the chain of the conveyor 1. The heavier the plate, the smaller the access resistance of the feedback resistor rod 310, and the stronger the magnetism of the regulating electromagnetic plate 47, so that the downward movement distance of the tensioning wheel 43 is greater, thereby increasing the tension of the chain on the conveyor 1. The conveyor 1 transmits power through the meshing of the chain and the sprocket, thereby pushing the plate forward. In this process, the chain The friction between the chain and the sprocket plays a key role. When the chain tension increases, the positive pressure between the chain and the sprocket increases. According to the friction formula f=μN (where f is the friction force, μ is the friction coefficient, and N is the positive pressure), when the friction coefficient remains unchanged, the positive pressure increases and the friction force also increases accordingly. This friction force is the conveying force that pushes the plate forward. Therefore, increasing the tension can increase the conveying force and ensure the stable conveying of the plate. Conversely, the lighter the plate, the smaller the tension of the conveyor 1, which in turn generates less pressure on the plate, avoiding the problem of excessive conveying pressure causing damage and breakage of the plate, and improving the conveying quality. When the conveyor 1 is working, the PLC controller 10 controls the air supply pump 63 to work, and the air supply pump 63 cooperates with the air supply pipe 62 to supply air to the blowing head 61, thereby blowing and cleaning the chain on the conveyor 1, reducing the dust and impurities carried on the chain, thereby avoiding the problem that the presence of dust will increase the friction between the chain and the sprocket, thereby causing the chain to wear more severely, and avoiding the problem that the impurities on the chain will affect the adhesion and distribution of the lubricant, thereby reducing the lubrication effect. The feedback conductive contact 311 and the feedback resistor rod 310 are also connected in series to the power supply circuit of the proportional solenoid valve 77. When the plate is heavier, the access resistance of the feedback resistor rod 310 is smaller. At this time, the chain tension of the conveyor 1 is greater, and the power supply current of the proportional solenoid valve 77 is greater. The proportional solenoid valve 77 is a solenoid valve that can continuously control the fluid flow, pressure and direction according to the size of the input electrical signal. It adjusts the displacement of the valve core by changing the current size of the electromagnet, thereby achieving Precise control of the valve opening. When the power supply current provided to the proportional solenoid valve 77 increases, the magnetic field strength generated by the electromagnet increases, and the force attracting the valve core to move also increases accordingly, so that the displacement of the valve core increases, and the degree of opening and closing of the valve becomes larger. A larger portion of the air supplied from the air supply pipe 62 to the blower head 61 is transported to the trigger shell 71 through the branch pipe 76, thereby gradually increasing the pressure in the trigger shell 71, and then driving the moving piston 72 to overcome the elastic force of the pressure spring 74 to move in the trigger shell 71 until the moving piston 72 presses on the trigger switch 75. At this time, the PLC controller 10 will control the automatic lubrication mechanism 5 to work. After the trigger switch 75 is pressed and triggered, the PLC controller 10 controls the on-off valve 79 on the pressure relief pipe 78 to open, thereby discharging the air filled in the trigger shell 71. Under the push-back action of the pressure spring 74, the moving piston 72 is reset to the initial position, and the next triggering work is continued. And when the plate is heavier, the chain tension of the conveyor 1 is greater, and the opening and closing degree of the proportional solenoid valve 77 is greater at this time, the air supply speed in the trigger shell 71 is faster, so that the interval time of the moving piston 72 pressing on the trigger switch 75 is shorter, thereby increasing the working frequency of the automatic lubrication mechanism 5. After increasing the tension of the chain, the contact between the chain and the sprocket is closer, resulting in an increase in positive pressure. Based on the friction formula, when the friction coefficient remains unchanged, the positive pressure increases, and the friction force also increases accordingly, thereby accelerating the wear of the chain. Increasing the frequency of adding lubricant can reduce the wear of the chain and ensure the service life of the chain. After the opening and closing degree of the proportional solenoid valve 77 increases, because the air supply speed of the air supply pump 63 remains unchanged, the air supply amount from the air supply pipe 62 to the blowing head 61 will be reduced, thereby reducing the blowing force of the blowing head 61 toward the chain, thereby preventing the connection structure on the chain from being relatively more separated due to the increase in the tension of the chain. Excessive wind force will make the lubricant on the surface of the chain more easily blown away, thereby causing the problem of aggravated chain wear. After the trigger switch 75 is pressed and triggered, the automatic lubrication mechanism 5 is started, and the feed pump 56 cooperates with the feed pipe 55 to transport the lubricant stored in the external lubricant barrel to the lubrication nozzle 54, and sprays the lubricant on the outside of the chain to quickly lubricate the chain of the conveyor 1. This process continues until the chain on the conveyor 1 runs a cycle, so that the chain is fully lubricated, and based on the adjustment of the tensioning force of the tensioning wheel 43 to the chain, when the force plate 42 drives the tensioning wheel 43 to move, it drives the transmission rack 511 to move synchronously, and the rotating shaft is driven by the meshing action of the transmission rack 511 and the transmission gear 510. 58 rotates synchronously, and the transmission shaft 52 drives the transmission shaft 52 through the transmission chain assembly 59 to drive the deflection block 53 and the lubricating nozzle 54 to deflect, and the use angle of the lubricating nozzle 54 is automatically adjusted, so that the lubricating nozzle 54 can adjust the angle of the lubricating spray synchronously based on the pressure of the tensioning wheel 43 on the chain to change the chain placement angle, so that the lubricating nozzle 54 and the chain are kept as parallel as possible to ensure the uniformity of the spraying, thereby improving the spraying quality. It should be noted that the lubricating nozzle 54 is a mechanical impact nozzle, which can automatically atomize the lubricating oil delivered therein.
