[0016] Compared with the prior art, the present invention provides a feeding and conveying device for an automobile part packaging machine, having the following beneficial effects:

[0017] 1. It can achieve the feeding effect of a conveyor belt. During the feeding process of the conveyor belt, once the amount of parts accumulated on the surface of the conveyor belt exceeds the rated amount, the device can stop the conveyor belt from running without shutting down the motor. When the amount of parts is lower than the rated amount, the conveyor belt can be started in time, thus preventing the occurrence of part accumulation caused by fast part conveying speed or slow part unloading speed, and improving the control degree of the equipment in terms of material quantity.

[0018] 2. By setting a gravity pre-tightening mechanism, the gravity pre-tightening mechanism can move longitudinally along the longitudinal support leg. Under its own gravity, the conveyor belt will be in a straightened state, and then the conveyor belt will be in a working state. Starting the drive motor will make the conveyor belt run in a fixed direction, thus achieving the gravity pre-tightening effect on the conveyor belt and the drive effect of the equipment.

[0019] 3. By setting up a linkage drive mechanism, when a large number of parts are blocked on one side of the end limit plate, relative friction will occur between the parts and the conveyor belt. When the friction between the two is greater than the elastic friction formed by the No. 1 coil spring, relative rotation will occur between the conical rotating plate and the annular inner convex structure. At this time, the conveyor belt is in a stationary state and will not transport parts. When the use of parts increases and the number decreases, and the transportation resistance caused by it is less than the maximum static friction between the conical rotating plate and the annular inner convex structure, the rotor will drive the drive roller and the conveyor belt to operate again, thereby preventing the accumulation of parts due to fast conveying of parts or slow unloading of parts.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1 、 Figure 2 and Figure 3 As shown in FIGS. 1, 2 and 3, a feeding and conveying device for an automobile part packaging machine includes two symmetric side guard plates 1, four symmetric longitudinal support legs 2 fixedly installed at the bottom of the side guard plates 1, a driven roller 3 rotatably installed between the two side guard plates 1 through bearings, a conveyor belt 4 sleeved around the driven roller 3, and an end limit plate 5 installed at the end of the side guard plate 1. It should be noted that the material conveying direction of the conveyor belt 4 needs to face the end limit plate 5. Therefore, the parts and materials on the surface of the conveyor belt 4 will be blocked on one side of the end limit plate 5.

[0031] In order to achieve the gravity pre-tightening effect on the conveyor belt 4 and the driving effect of the equipment, please refer to FIGS. 4 - 6. Figure 1 - Figure 8, a gravity preload mechanism 6 is required, which has a vertical component mounting plate 64 that can slide longitudinally along the two longitudinal support legs 2 under its own gravity and a drive motor 67 mounted at the end of the vertical component mounting plate 64. For the specific structure of the gravity preload mechanism 6, please refer to Figure 1 , Figure 2 and Figure 4 , further comprising two No. 1 rod sleeves 61, wherein the interior of the No. 1 rod sleeve 61 is provided with a No. 1 sleeve hole 62 sleeved on the periphery of the longitudinal support leg 2, a vertical component mounting plate 64 is fixedly installed between the No. 1 rod sleeves 61 through a No. 1 horizontal support rod 63, a rotor mounting hole 65 with both ends being open is arranged at the center of the vertical component mounting plate 64, a motor fixing housing 66 is fixedly installed at one end of the vertical component mounting plate 64, a driving motor 67 in a horizontal state is fixedly installed inside the motor fixing housing 66, a rotor 68 of the driving motor 67 passes through the rotor mounting hole 65, and the structure of the rotor 68 at the passing portion is connected by an axis. The bearing is installed inside the rotor mounting hole 65, and the other end of the vertical component mounting plate 64 is provided with a raised mounting ring structure 69 which is an integral structure therewith and is located on the periphery of the rotor 68. The overall weight of the gravity pre-tensioning mechanism 6 is sufficient to make the conveyor belt 4 in a stretched state under working conditions. The gravity pre-tensioning mechanism 6 can move longitudinally along the longitudinal support leg 2. Under the action of its own gravity, the conveyor belt 4 will be stretched and stretched, and then the conveyor belt 4 will be in a working state. Starting the drive motor 67 will make the conveyor belt 4 run in a directional manner, thereby achieving the gravity pre-tensioning effect on the conveyor belt 4 and the driving effect of the equipment.

[0032] To prevent the accumulation of parts due to fast conveying of parts or slow unloading of parts, please refer to Figure 1 - Figure 8 , a linkage drive mechanism 7 is required, which includes a driving roller 71 mounted on the other end of the vertical component mounting plate 64 through a bearing and capable of driving the conveyor belt 4 when rotating, a horizontal rotating shaft 76 located inside the driving roller 71 and rotating with the rotor 68 of the driving motor 67, and a conical rotating plate 79 rotating with the horizontal rotating shaft 76 and driving the driving roller 71 to rotate by friction. For the specific structure of the linkage drive mechanism 7, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, further comprising an external threaded rod 78 and a threaded sleeve 711. A first component moving cavity 72 with open ends is provided at the center of the driving roller 71. An annular inner convex structure 73 integrated with the driving roller 71 is provided in the middle region of the first component moving cavity 72. A first rod body through hole 74 is provided at the center of the annular inner convex structure 73. A first conical friction surface 75 is provided at the end of the annular inner convex structure 73 away from the rotor 68. A third rod body through hole 715 is provided at the center of the conical rotating plate 79. A second conical friction surface 710 matching the first conical friction surface 75 is provided at one end of the conical rotating plate 79. The shaft body of the horizontal rotating shaft 76 penetrates through the first rod body through hole 74 and the third rod body through hole 715. A rotor fixing groove 77 with an inner concave structure for fixedly installing the rotor 68 is provided at one end of the horizontal rotating shaft 76. An external threaded rod 78 in a horizontal state is fixedly installed at the other end of the horizontal rotating shaft 76. An internal threaded hole 712 with open ends is provided at the center of the threaded sleeve 711. The internal threaded hole 712 of the threaded sleeve 711 is installed on the rod body of the external threaded rod 78 through a threaded structure. The outer circumferential surface of the threaded sleeve 711 is installed at the center of a rotating limit disc 713 through a bearing. A first helical spring 714 in a compressed state is sleeved between the rotating limit disc 713 and the conical rotating plate 79. The port of the first conical friction surface 75 near the first rod body through hole 74 intersects with one port of the first rod body through hole 74, and the diameter of this port is smaller than the diameter of the other end of the first conical friction surface 75. The diameter of the first rod body through hole 74 is larger than the cross-sectional dimension of the horizontal rotating shaft 76, and the structural shape of the cross-section of the horizontal rotating shaft 76 matches the structural shape of the cross-section of the third rod body through hole 715, both being polygonal structures. The structural dimension of the cross-section of the horizontal rotating shaft 76 matches the structural dimension of the cross-section of the third rod body through hole 715. The threaded structure includes an internal threaded structure provided in the internal threaded hole 712 and an external threaded structure provided on the rod body of the external threaded rod 78, and the internal threaded structure matches the external threaded structure. The rotor 68 will drive the horizontal rotating shaft 76 to rotate, and due to the structural shape, it will drive the conical rotating plate 79 to rotate. Due to the frictional force of contact between the conical rotating plate 79 and the annular inner convex structure 73, the conical rotating plate 79 will drive the driving roller 71 to rotate, and the driving roller 71 will drive the entire conveyor belt 4 to operate under the action of frictional force, so as to conduct directional transportation of the mechanical components located on the upper surface of the conveyor belt 4. When a large number of components are blocked on one side of the end limiting plate 5, at this time, a relative friction phenomenon will occur between the components and the conveyor belt 4. Due to the increase in frictional force, the driving resistance of the driving roller 71 to the conveyor belt 4 will increase. Similarly, the frictional force between the conical rotating plate 79 and the annular inner convex structure 73 will also increase. When the frictional force between the two is greater than the elastic frictional force formed by the first helical spring 714, a relative rotation phenomenon will occur between the conical rotating plate 79 and the annular inner convex structure 73. At this time, the rotor 68 of the driving motor 67 will rotate normally,The conveyor belt 4 is in a stationary state and does not transport parts. When the usage of parts increases and the quantity decreases, and the transportation resistance caused by it is less than the maximum static friction between the conical rotating plate 79 and the annular inner convex structure 73, the rotor 68 will drive the driving roller 71 and the conveyor belt 4 to operate again, thereby preventing the accumulation of parts caused by fast conveying speed or slow unloading of parts.

[0033] Of course, the directional rotation of the threaded sleeve 711, due to the threaded structure connection, will make the threaded sleeve 711 move in a directional manner along the external threaded rod 78, and then drive the rotating limit plate 713 to move in a directional manner, so as to change the distance between the rotating limit plate 713 and the conical rotating plate 79, thereby changing the elastic strength of the No. 1 coil spring 714 at this time. The change in the elastic strength will change the maximum static friction force between the conical rotating plate 79 and the annular inner convex structure 73. The greater the distance between the rotating limit plate 713 and the conical rotating plate 79, the smaller the elastic strength of the No. 1 coil spring 714, and the smaller the maximum static friction force between the conical rotating plate 79 and the annular inner convex structure 73, the less the amount of transportation of the conveyor belt 4; conversely, the greater the transportation amount.

[0034] To clean the conveyor belt 4, please refer to Figure 1 - Figure 8 , it is necessary to set up an elastic resistance type wiping mechanism 8, which is provided with a cylindrical hollow shell 81 installed between the two longitudinal supporting legs 2 and having a hollow interior, an inner movable plate 87 placed inside the cylindrical hollow shell 81 and moving along the axial direction of the cylindrical hollow shell 81, a telescopic resistance rod 810 moving with the inner movable plate 87, and a sponge wiping body 812 moving with the telescopic resistance rod 810, resisting against the conveying surface of the conveyor belt 4 and wiping the conveying surface of the conveyor belt 4. For the specific structure of the elastic resistance type wiping mechanism 8, please refer to Figure 1 , Figure 3 , Figure 7 and Figure 8, further comprising a second helical spring 88 for providing elastic pressure. A nested base 82 is installed at the bottom end of the cylindrical hollow housing 81. A horizontally disposed second horizontal support rod 83 is fixedly installed at the center of the nested base 82. A second rod sleeve 84 is fixedly installed at each end of the second horizontal support rod 83. A second sleeve hole 85 fixed to the outside of the longitudinal support leg 2 is provided at the center of the second rod sleeve 84. A second component activity cavity 86 is provided inside the cylindrical hollow housing 81. A second rod body through hole 89 communicating the outside space and the top end of the second component activity cavity 86 is provided at the top end of the cylindrical hollow housing 81. An inner movable plate 87 capable of moving axially along the second component activity cavity 86 is placed inside the cylindrical hollow housing 81 at a position corresponding to the second component activity cavity 86. A compressed second helical spring 88 is placed at the bottom end of the inner movable plate 87. A telescopic contact rod 810 passing through the second rod body through hole 89 is fixedly installed at the top end of the inner movable plate 87. A rectangular embedding plate 811 is fixedly installed at the top end of the telescopic contact rod 810. A sponge wiper 812 capable of wiping the moving conveyor belt 4 is embedded at the top of the rectangular embedding plate 811. Under the action of the second helical spring 88, the sponge wiper 812 will contact the conveying surface of the conveyor belt 4 in a manner of elastic pressure. When the conveyor belt 4 operates, relative friction will occur between the conveyor belt 4 and the sponge wiper 812, and the sponge wiper 812 can wipe the conveying surface of the conveyor belt 4. Since the cross-sectional structural shape of the second component activity cavity 86 matches that of the inner movable plate 87 and is a polygonal structure, and the cross-sectional structural dimensions of the second component activity cavity 86 match those of the inner movable plate 87, the sponge wiper 812 can clean the conveyor belt 4 at a fixed angle.

[0035] During use, the material conveying direction of the conveyor belt 4 needs to face the end limiting plate 5. When the driving motor 67 is turned on, the rotor 68 will drive the horizontal rotating shaft 76 to rotate. Due to the structural shape, the conical rotating plate 79 will be driven to rotate. Due to the frictional resistance between the conical rotating plate 79 and the annular inner convex structure 73, the conical rotating plate 79 will drive the driving roller 71 to rotate. The driving roller 71 will then drive the entire conveyor belt 4 to operate under the action of friction, so as to directionally transport the mechanical parts located on the upper surface of the conveyor belt 4. When a large number of parts are blocked on one side of the end limiting plate 5, at this time, relative friction will occur between the parts and the conveyor belt 4. Due to the increase in friction, the driving resistance of the driving roller 71 to the conveyor belt 4 will increase. Similarly, the friction between the conical rotating plate 79 and the annular inner convex structure 73 also increases. When the friction between the two is greater than the elastic frictional force formed by the first helical spring 714, relative rotation will occur between the conical rotating plate 79 and the annular inner convex structure 73. At this time, the rotor 68 of the driving motor 67 will rotate normally, while the conveyor belt 4 is in a stationary state and will not transport the parts. When the usage amount of the parts increases and the quantity decreases, and the resulting transportation resistance is less than the maximum static friction between the conical rotating plate 79 and the annular inner convex structure 73, the rotor 68 will drive the driving roller 71 and the conveyor belt 4 to operate again, and continue to realize the transportation function of the parts. In the feeding process of the conveyor belt 4 in this device, once the amount of parts accumulated on the surface of the conveyor belt 4 exceeds the rated amount, the device can stop the conveyor belt 4 from operating without turning off the driving motor 67, and when the amount of parts is lower than the rated amount, the conveyor belt 4 can be started to operate in a timely manner, so as to prevent the occurrence of part accumulation caused by fast part transportation speed or slow part unloading speed, and improve the control degree of the equipment in terms of the amount of materials (in short, when a large amount of accumulation occurs in the conveying amount of the conveyor belt 4, the frictional force that needs to be overcome for the operation of the conveyor belt 4 will increase, and by controlling the maximum operation intensity of the conveyor belt 4 during operation, the above phenomenon can be prevented. When a large amount of accumulated parts are consumed to a certain extent, the conveyor belt 4 can start to operate independently, so as to realize the function of autonomous material quantity control).
