Description

Technical Field

[0001] The utility model relates to the technical field of flocking processing equipment, in particular to an automatic feeding mechanism used in flocking equipment. Background Art

[0002] Flocking is a technology or method of vertically fixing short fibers on a substrate coated with an adhesive; the flocking technology has the advantages of strong three-dimensional sense, bright colors, soft hand feeling, non-fluffing, wear resistance, flatness without gaps, etc., and is a widely used surface decoration technology. The automatic feeding mechanism used in flocking equipment is a key component on the production line, and its main function is to realize the automatic conveying and positioning of materials to support the efficient progress of the flocking process; the existing automatic feeding mechanisms for flocking equipment can basically meet the daily processing requirements. The feeding part generally includes two structures: blanking and spiral feeding. Most of the existing feeding mechanisms use two groups of motors for combined drive, which is difficult to ensure the synchronization of blanking and feeding, and at the same time increases the operating energy consumption of the mechanism; moreover, the transmission part structure of the existing feeding mechanism is simple. When fibers accumulate at the bottom of the conveying rod, it will increase the torsional stress on the conveying rod, and excessive torsional stress is likely to damage the motor, thus shortening the service life of the mechanism. Therefore, it is very necessary to design an automatic feeding mechanism for flocking equipment. Content of the Utility Model

The feeding part generally includes two structures: blanking and spiral feeding. Most of the traditional mechanisms use two groups of motors for combined drive, which is difficult to ensure the synchronization of blanking and feeding, and at the same time increases the operating energy consumption of the mechanism; moreover, the transmission part structure of the existing feeding mechanism is simple. When fibers accumulate at the bottom of the conveying rod, it will increase the torsional stress on the conveying rod, and excessive torsional stress is likely to damage the motor, shortening the service life of the mechanism.

[0004] To solve the above technical problems, the present utility model provides the following technical solutions: an automatic feeding mechanism used in a flocking device, including a closed bracket, a linkage assembly, a transmission ring, and a force-relieving locking assembly. On one side inside the closed bracket, there is a transmission bottom plate in the linkage assembly. A first transmission platform and a second transmission platform are respectively rotatably connected to the transmission bottom plate. A first sprocket and a second sprocket are respectively arranged on the first transmission platform and the second transmission platform. The first sprocket and the second sprocket are connected to each other through a first transmission chain. A third sprocket is sleeved on the top of the second transmission platform. The third sprocket is wound in a second transmission chain, and the second transmission chain is connected to a fourth sprocket in a matching manner. The fourth sprocket is fixed on the output end of a feeding motor. A transmission ring is arranged on the top of the first transmission platform. A locking plate in the force-relieving locking assembly is fixedly sleeved in a groove opened on the transmission ring. The locking plate is evenly provided with first springs. One end of each first spring is fixed on a locking cap. The locking cap presses tightly on a transmission block. A locking groove is opened on one side of the bottom of the transmission block. The locking groove is slidably connected to a connecting ring through a guide rod. The connecting ring is fixed on the top of the transmission ring. A second spring is arranged between the transmission block and the connecting ring. The connecting ring is rotatably connected to the bottom of a spiral bottom plate. Transmission notches are evenly opened on the bottom of the spiral bottom plate. One end of the transmission block is slidably connected to the transmission notch.

[0005] As a further technical solution of the present utility model, the linkage assembly is composed of a transmission bottom plate, a first transmission platform, a second transmission platform, a first sprocket, a second sprocket, a third sprocket, a fourth sprocket, a first transmission chain, a second transmission chain, and a feeding motor. The feeding motor is fixed on the top of the transmission bottom plate.

[0006] As a further technical solution of the present utility model, the force-relieving locking assembly is composed of a locking plate, a first spring, a locking cap, a locking groove, a transmission block, a transmission notch, a connecting ring, a second spring, and a spiral bottom plate. A closing member is slidably connected to the spiral bottom plate, and the closing member is symmetrically fixed on the transmission bottom plate.

[0007] As a further technical solution of the present utility model, a conveying rod is arranged on the top of the spiral bottom plate.

[0008] As a further technical solution of the present utility model, a discharging hopper is arranged on one side of the closed bracket.

[0009] As a further technical solution of the present utility model, a feeding conveyor belt is connected to the top of the second transmission platform through bevel gears. The feeding conveyor belt is connected to the transmission bottom plate in a matching manner. A raw material storage box is fixedly connected to the feeding conveyor belt, and the raw material storage box is fixed in the closed bracket.

[0010] As a further technical solution of the present utility model, the top end of the conveying rod is rotatably connected to the top of the closed bracket.

[0011] The automatic feeding mechanism used in the flocking equipment provided by the utility model has the advantages that: the first transmission platform and the second transmission platform are respectively connected to the transmission ring and the raw material storage box, and the first transmission chain is cooperated to make the first sprocket and the second sprocket synchronously drive the first transmission platform and the second transmission platform to form a linkage operation structure. During the feeding process, the feeding motor drives the third sprocket on the first transmission chain to rotate through the fourth sprocket, thereby driving the linkage operation structure to operate synchronously. A single motor is used to cooperate with the linkage component to drive the feeding mechanism, which optimizes the traditional driving mode, ensures the synchronization of unloading and feeding, and reduces the operating energy consumption of the mechanism; during the rotation of the first transmission platform, the spiral bottom plate and the conveying rod are driven to rotate through the transmission block in the transmission notch. When the torsional stress on the conveying rod is too large due to the accumulation of materials, the transmission block squeezes the second spring to cooperate with the inclined surface of the transmission notch to slide toward the inside of the connecting ring. When the transmission block is completely separated from the transmission notch, the first spring pushes the locking cap into the locking groove to lock the transmission block. At this time, the connecting ring is rotated and connected to the bottom of the spiral bottom plate to complete the unloading process of the conveying rod, preventing the torsional stress from being too large to damage the feeding motor, thereby extending the service life of the mechanism.

[0023] Please refer to Figure 1-7, an embodiment provided by the present utility model: an automatic feeding mechanism for a flocking device, including a closed bracket 1, a linkage assembly 2, a transmission ring 3 and a force-off locking assembly 4. A transmission base plate 21 in the linkage assembly 2 is provided on one side inside the closed bracket 1. A first transmission table 22 and a second transmission table 23 are respectively rotatably connected to the transmission base plate 21. A first sprocket 24 and a second sprocket 25 are respectively provided on the first transmission table 22 and the second transmission table 23. The first sprocket 24 and the second sprocket 25 are cooperatively connected to each other through a first transmission chain 28. A third sprocket 26 is sleeved on the top of the second transmission table 23. The third sprocket 26 is wound in a second transmission chain 29, and the second transmission chain 29 is cooperatively connected to a fourth sprocket 27. The fourth sprocket 27 is fixed on the output end of a feeding motor 30. A transmission ring 3 is provided on the top of the first transmission table 22. A locking plate 41 in the force-off locking assembly 4 is fixedly sleeved in a groove opened on the transmission ring 3. The locking plate 41 is evenly provided with first springs 42. One end of each first spring 42 is fixed on a locking cap 43. The locking cap 43 tightly presses on a transmission block 45. A locking groove 44 is opened on one side at the bottom of the transmission block 45, and the locking groove 44 is slidably connected to a connecting ring 47 through a guide rod. The connecting ring 47 is fixed on the top of the transmission ring 3. A second spring 48 is provided between the transmission block 45 and the connecting ring 47. The connecting ring 47 is rotatably connected to the bottom of a spiral base plate 49. The bottom of the spiral base plate 49 is evenly provided with transmission notches 46. One end of the transmission block 45 is slidably connected to the transmission notch 46. The linkage assembly 2 is composed of a transmission base plate 21, a first transmission table 22, a second transmission table 23, a first sprocket 24, a second sprocket 25, a third sprocket 26, a fourth sprocket 27, a first transmission chain 28, a second transmission chain 29 and a feeding motor 30. The feeding motor 30 is fixed on the top of the transmission base plate 21. The force-off locking assembly 4 is composed of a locking plate 41, first springs 42, locking caps 43, locking grooves 44, transmission blocks 45, transmission notches 46, connecting rings 47, second springs 48 and spiral base plates 49. A closing member 7 is slidably connected to the spiral base plate 49, and the closing member 7 is symmetrically fixed on the transmission base plate 21. A conveying rod 5 is provided on the top of the spiral base plate 49. A discharge hopper 6 is provided on one side of the closed bracket 1. The top of the second transmission table 23 is cooperatively connected to a feeding conveyor belt through bevel gears. The feeding conveyor belt is cooperatively connected to the transmission base plate 21. A raw material storage box 8 is fixedly connected to the feeding conveyor belt, and the raw material storage box 8 is fixed in the closed bracket 1. The top end of the conveying rod 5 is rotatably connected to the top of the closed bracket 1. The conveying rod 5 is a spiral conveying structure. During the rotation of the first transmission table 22, the screw structure that can rotate lifts the material at the bottom of the conveying rod 5 to the top of the closed bracket 1, and then falls into the discharge hopper 6 on one side of the closed bracket 1 to complete the automatic feeding process for the flocking device;

[0024] Specifically, in the present utility model, a first transmission platform 22 and a second transmission platform 23 are respectively connected to a transmission ring 3 and a raw material storage box 8. The first sprocket 24 and the second sprocket 25 cooperate with the first transmission chain 28 to synchronously drive the first transmission platform 22 and the second transmission platform 23 to form a linkage operation structure. During the feeding process, a feeding motor 30 drives the third sprocket 26 on the first transmission chain 28 to rotate through the fourth sprocket 27, thereby driving the linkage operation structure to operate synchronously. Using a single set of motors to cooperate with the linkage assembly 2 to drive the feeding mechanism optimizes the traditional driving method, ensures the synchronization of blanking and feeding, and reduces the operating energy consumption of the mechanism. When feeding, the materials in the raw material storage box 8 are conveyed to one side of the spiral bottom plate 49 through the feeding conveyor belt, and driven by the rotation of the conveying rod 5, they move upward along the conveying rod 5 and finally are discharged from the discharge hopper 6 to complete the feeding. During the rotation of the first transmission platform 22, the transmission block 45 in the transmission notch 46 drives the spiral bottom plate 49 and the conveying rod 5 to rotate. When the distortion stress borne by the conveying rod 5 is too large due to material accumulation, the transmission block 45 will squeeze the second spring 48 and slide into the interior of the connecting ring 47 along the inclined surface of the transmission notch 46. When the transmission block 45 completely disengages from the transmission notch 46, the first spring 42 pushes the locking cap 43 into the locking groove 44 to lock the transmission block 45. At this time, the connecting ring 47 is rotatably connected to the bottom of the spiral bottom plate 49 to complete the unloading process of the conveying rod 5, preventing the distortion stress from being too large and damaging the feeding motor 30, thereby extending the service life of the mechanism.
