Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fly delivery paper feeding, and particularly relates to a fly delivery conveying device of a paper laminating machine. BACKGROUND

[0002] The fly delivery conveying device is widely used in paper laminating processing equipment and is mainly used for separating and stably conveying the stacked paper sheets to the next process. The fly head, as the core component for performing the actions of paper suction and feeding, usually realizes power transmission through a universal shaft mechanism and reciprocates forward and backward in the machine frame to adapt to the requirements of different paper stack heights and paper feeding rhythms.

[0003] In the prior art, the universal shaft mechanism usually adopts a telescopic structure to adapt to the active stroke of the fly head. For example, a fly delivery conveying device in the application No. CN202211001069.7 includes a connecting sleeve, a connecting rod and a universal coupling. One end of the connecting rod is slidingly fitted in the connecting sleeve, the other end is connected with a power source through the universal coupling, and the other end of the connecting sleeve is connected with the fly head through another universal coupling. The structure can continuously transmit the power during the forward and backward movement of the fly head, has good synchronism and transmission stability.

[0004] However, in the actual operation process, the fly head needs to be frequently and rapidly adjusted forward and backward, which causes the connecting rod to continuously perform axial sliding movement in the connecting sleeve while accompanying the rotary movement, forming a complex friction working condition. The continuous relative movement makes the prismatic fitting surface between the connecting rod and the connecting sleeve extremely easy to be seriously worn due to insufficient lubrication, and further causes the following problems:

[0005] 1. The friction resistance increases, which leads to the decrease of power transmission efficiency and the increase of motor load;

[0006] 2. The fitting gap gradually expands, which causes transmission vibration, noise increase and affects the paper feeding precision;

[0007] 3. Local overheating accelerates material fatigue and shortens the service life of the component;

[0008] At present, the conventional lubrication methods mainly include periodic manual greasing or pre-coating of lubricating oil during assembly. However, these methods have obvious defects:

[0009] 1. The manual lubrication has a long period and is not timely, which is difficult to meet the lubrication requirements in continuous operation;

[0010] 2. The greasing is unevenly distributed and cannot effectively cover the high-speed sliding area;

[0011] 3. The method lacks the ability of continuous oil supply for dynamic pairs and cannot meet the long-term stable operation requirements of automatic and high-precision equipment.

[0012] Although some equipment attempts to adopt centralized lubrication system, the oil supply path is mostly fixed, which cannot adapt to the constantly changing relative position between the connecting rod and the connecting sleeve, resulting in oil path breakage, leakage or failure to accurately reach the friction interface.

[0013] Therefore, how to realize continuous, stable and accurate lubrication of the sliding fit surface between the connecting sleeve and the connecting rod under the working condition of the fly head continuous activity has become a technical problem to be solved in the field. There is no effective solution in the prior art that can meet the dual requirements of dynamic motion and reliable lubrication, which seriously restricts the operation stability and service life of the fly transmission device.

[0051] The following will refer to the appendices in the embodiments of the present invention. Figures 1-19 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0052] Example:

[0053] like Figures 1 to 19 As shown, this invention discloses a feeder conveyor device for a paper mounting machine, such as... Figures 1 to 3 As shown, the device includes a machine frame 10 and a feeder head 11 that is movably arranged back and forth within the machine frame 10. A universal joint mechanism connected to the feeder head 11 is provided on one side of the machine frame 10. The machine frame 10 also has a power input mechanism for driving the universal joint mechanism to rotate. The feeder head 11 itself is a prior art device used for separating and conveying paper, and the movement of the feeder head 11 is also described in prior art, such as... Figure 4 and Figure 5As shown, the universal shaft mechanism includes a connecting sleeve 2, a connecting rod 3, a first universal joint 4 and a second universal joint 5. The connecting rod 3 is prismatic, one end of which is slidingly fitted in the connecting sleeve 2 and can freely stretch and retract in the axial direction while transmitting torque. The other end of the connecting rod 3 is connected with the power input mechanism through the first universal joint 4, and the other end of the connecting sleeve 2 is connected with the fly head 11 through the second universal joint 5, ensuring stable transmission during the forward and backward movement of the fly head 11.

[0054] The first universal joint 4 is the core part of the lubricating system of the present application, as shown in Figure 6 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 14 , which specifically includes a connecting shaft 41 connected with the power input mechanism, a connecting shaft sleeve 42 fixedly sleeved on the connecting rod 3, and a cross shaft 43 located between the connecting shaft 41 and the connecting shaft sleeve 42. The connecting shaft 41 and the connecting shaft sleeve 42 are integrally formed with a universal joint fork 44 at one end facing each other. The upper and lower sides of the cross shaft 43 are rotatably connected to the universal joint fork 44 of the connecting shaft 41, and the left and right sides of the cross shaft 43 are rotatably connected to the universal joint fork 44 of the connecting shaft sleeve 42, forming a typical cross shaft 43 type universal joint structure that can adapt to multi-angle swinging. An oil inlet sleeve 62 is rotatably connected to the outside of the connecting shaft 41, which does not rotate with the connecting shaft 41. An oil inlet nozzle 61 is connected to the oil inlet sleeve 62 for connecting to an external lubricating oil source. An integral outer protruding ring 411 is provided on the outer side wall of the connecting shaft 41, and an annular groove 412 is formed in the outer protruding ring 411, which is in communication with the oil inlet nozzle 61 to form an initial gathering area of lubricating oil. A first oil channel 413 is formed in the connecting shaft 41 and penetrates out of the end of the connecting shaft 41 facing the cross shaft 43, and a connecting oil channel 414 is formed in the connecting shaft 41 and communicates with the annular groove 412 and the first oil channel 413. A second oil channel 431 is formed in the middle of the cross shaft 43, and a third oil channel 31 is formed in the middle of the connecting rod 3. The first oil channel 413 and the second oil channel 431, and the second oil channel 431 and the third oil channel 31 are connected by a pressure-resistant hose 45. The hose 45 is made of flexible material, such as polyurethane (PU) or PTFE composite hose. A plurality of lubricating oil holes 32 are formed in the connecting rod 3 and penetrate out of the side wall, which are in communication with the third oil channel 31, so as to deliver lubricating oil to the sliding fit surface of the connecting rod 3 and the connecting sleeve 2 through the lubricating oil holes 32.

[0055] Further, as shown in Figure 13As shown, the third oil passage 31 penetrates the connecting rod 3 axially from one end of the connecting rod 3 to a middle position of the connecting rod 3, and at the end of the third oil passage 31 of the connecting rod 3, a bifurcated oil passage 33 is communicated radially, and the connecting rod 3 is provided with an equal oil passage 34 at both ends of the bifurcated oil passage 33, the middle part of the equal oil passage 34 is communicated with the bifurcated oil passage 33, and a plurality of annular communication oil passages 35 are communicated between the two equal oil passages 34, and a plurality of lubricating oil holes 32 penetrating the side wall of the connecting rod 3 are uniformly distributed on each annular communication oil passage 35, through which the lubricating oil flows out to directly lubricate the sliding fit surface between the connecting rod 3 and the connecting sleeve 2. Since the middle part of the connecting rod 3 is the part that is most frequently rubbed with the connecting sleeve 2, this oil passage design prioritizes middle lubrication to achieve efficient and uniform distribution of lubricating oil. It should be noted that in order to form the annular communication oil passage 35, the equal oil passage 34 and the bifurcated oil passage 33, the connecting rod 3 can be manufactured in parts and then welded, which is a known technology to those skilled in the art.

[0056] Wherein since the connecting rod 3 is prismatic, a prismatic fitting cavity 21 penetrating one end of the connecting sleeve 2 is formed on the connecting sleeve 2, and one end of the connecting rod 3 is slidingly fitted in the prismatic fitting cavity 21. The connecting rod 3 is slidingly fitted with the prismatic fitting cavity 21 of the connecting sleeve 2 in a prismatic structure, which can not only transmit torque but also realize axial sliding. On this basis, a plurality of lubricating oil holes 32 are uniformly distributed on each side surface of the connecting rod 3 and are communicated with the annular communication oil passage 35, ensuring that each prismatic surface can be fully lubricated, effectively preventing corner wear, loose fit and transmission jitter caused by uneven lubrication, and improving the accuracy and stability of power transmission.

[0057] As shown in the drawings, Figures 1 to 5As shown, two shaft seats 71 are fixedly connected on the machine frame 10, two guide rods 72 are fixedly connected between the two shaft seats 71, a sliding plate 73 is arranged on the guide rods 72, a guide sleeve 74 is fixedly connected on the sliding plate 73 and is slidably fitted on the guide rods 72, the guide sleeve 74 ensures that the sliding plate 73 moves stably, a bevel gear connecting plate 75 is fixedly connected on the sliding plate 73, and the power input mechanism comprises a first bevel gear 76, a second bevel gear 77, a transmission prism rod 78, a third bevel gear 79 and a fourth bevel gear 80, the transmission prism rod 78 is prism-shaped, both ends of the transmission prism rod 78 are rotatably connected on the shaft seats 71, the first bevel gear 76 is rotatably connected on the machine frame 10, the second bevel gear 77 is fixedly connected on one end of the transmission prism rod 78 and is engaged with the first bevel gear 76, the third bevel gear 79 is rotatably connected on the sliding plate 73 and is slidably fitted on the transmission prism rod 78 and can move forward and backward with the sliding plate 73, the fourth bevel gear 80 is rotatably connected on the bevel gear connecting plate 75 and is fixedly connected with the connecting shaft 41, the third bevel gear 79 is engaged with the fourth bevel gear 80, and power is transmitted to the universal shaft mechanism, the oil inlet sleeve 62 is fixed on the bevel gear connecting plate 75, so that the oil inlet sleeve 62 does not rotate with the connecting shaft 41 and moves synchronously with the bevel gear connecting plate 75, and in addition, a flying motor 86 and a transmission mechanism for driving the first bevel gear 76 to rotate are arranged on the machine frame 10. The transmission mechanism specifically comprises a bevel gear synchronous pulley 87, a motor synchronous pulley 88 and a synchronous belt 89, the bevel gear synchronous pulley 87 is fixedly connected on the first bevel gear 76, the flying motor 86 is fixedly installed on the machine frame 10, the motor synchronous pulley 88 is fixed on the output shaft of the flying motor 86, and the synchronous belt 89 is arranged in cooperation on the bevel gear synchronous pulley 87 and the motor synchronous pulley 88, thereby forming a complete power transmission chain.

[0058] As shown, Figure 14 The oil inlet sleeve 62 comprises an assembly ring mouth 62 for rotatingly fitting the outer protruding ring 411, the outer protruding ring 411 of the connecting shaft 41 is embedded in the assembly ring mouth 62 of the oil inlet sleeve 62, and the limiting plate 63 for limiting the outer protruding ring 411 in the assembly ring mouth 62 is fixedly connected on the oil inlet sleeve 62, thereby preventing the shaft from being axially separated out.

[0059] As shown, Figure 11 , Figures 15 to 17 A tooth lubricating passage 801 penetrating through the fourth bevel gear 80 towards the end of the connecting shaft 41 is arranged in the fourth bevel gear 80, a sub-connection oil channel 415 connected to the first oil channel 413 and leading to the tooth lubricating passage 801 is arranged in the connecting shaft 41, and a plurality of tooth lubricating oil holes 80 leading from the tooth lubricating passage 801 to the tooth groove are arranged in the fourth bevel gear 80. This structure allows a small amount of lubricating oil to flow to the tooth lubricating oil holes 80 of the fourth bevel gear 80 from the tooth lubricating passage 801 to the tooth groove, lubricating the meshing surface of the third bevel gear 79 and the fourth bevel gear 80, thereby realizing automatic lubrication of the gear transmission.

[0060] AsFigure 11 As shown, in order to prevent lubricating oil leakage, an oil seal 90 is provided between the connecting shaft 41 and the fourth bevel tooth 80, and sealing rings 91 are provided on both sides of the annular groove 412 between the oil inlet sleeve 62 and the connecting shaft 41. The setting of the oil seal 90 and the sealing rings 91 are common knowledge to those skilled in the art, so they will not be described in detail here.

[0061] like Figure 5 , Figure 18 as well as Figure 19 As shown, an inner annular oil groove 741 is formed on the inner side wall of the guide sleeve 74, and a connecting pipe 81 is connected between the guide sleeves 74 on the two guide rods 72. The connecting pipe 81 connects the inner annular oil grooves 741 in the two guide sleeves 74, so that lubricating oil can simultaneously lubricate the sliding surfaces of the guide rods 72 and the guide sleeves 74 on both sides. One of the guide sleeves 74 is connected to a second oil inlet 84 leading to the inner annular oil groove 741 for introducing lubricating oil. This structure is used to introduce lubricating oil when the sliding plate 73 needs to move frequently. When the sliding plate 73 does not need to move, it is not necessary to introduce lubricating oil.

[0062] Additionally, a lubricating sponge sleeve 85 is fixedly connected to the fourth bevel tooth 80 and slidably sleeved on the transmission prism 78. A secondary connecting pipe 82 extending above the lubricating sponge sleeve 85 is connected to the connecting pipe 81, and a nozzle 83 facing the lubricating sponge sleeve 85 is connected to the secondary connecting pipe 82. Some lubricating oil is sprayed from the nozzle 83 through the secondary connecting pipe 82 and absorbed by the lubricating sponge sleeve 85. As the sliding plate 73 moves, the lubricating sponge sleeve continuously wipes the surface of the transmission prism 78, providing it with long-term lubrication and ensuring the smooth sliding of the third bevel tooth 79 on the prism.

[0063] like Figure 1 As shown, a support frame 92 is provided on the upper side of the machine frame 10. A lubricating oil control center 93 is integrated on the support frame 92. This center includes a pump body and a control valve body, both of which are combinations of existing technologies. It is mainly used to control the timing and flow rate of lubricating oil delivery. The lubricating oil control center 93 can be connected to the oil inlet 61 and the second oil inlet 84 via a spiral retractable hose 45, accommodating the movement of the sliding plate 73. The system automatically supplies oil to each lubrication point according to preset time or operating parameters, achieving intelligent and centralized lubrication management of the entire system.

[0064] Furthermore, to prevent lubricating oil from dripping and contaminating the paper or the equipment environment, an oil collection tray can be added below the drive rod and guide rod. The oil collection tray is fixedly installed on the machine frame directly below the drive rod and guide rod, and is securely connected by bolts or other fasteners. The height of the oil collection tray should be adjusted appropriately to ensure that it can effectively receive dripping lubricating oil without affecting the normal operation of moving parts such as the sliding plate and feeder head.
