Description

Technical Field

[0001] The utility model relates to the technical field of fiberboard processing, in particular to an automatic feeding mechanism for fiberboard processing. Background Technique

[0002] Fiberboard, also known as density board, is a man-made board made of wood fiber or other plant fiber as raw materials and applying urea-formaldehyde resin or other suitable adhesives. With the rapid development of China's economy and the continuous improvement of the urbanization rate, fiberboard products with stable quality, high environmental protection level, meeting differential requirements and having safety flame retardant function have broad market space. The rapid development of industries such as real estate, furniture, interior decoration, and packaging in China in the future and the completion and production of fast-growing industrial timber raw material bases will drive the steady growth of the demand and export volume of fiberboard, and the proportion of fiberboard products in the total production of man-made boards will also be greatly increased. Therefore, the processing and production work of fiberboard only moves forward and not backward, so the continuous improvement of fiberboard processing technology is needed.

[0003] In the processing of fiberboard, the feeding device at the very beginning and also extremely important directly affects the speed and quality of fiberboard processing. Then, in the context of meeting the processing quality and quantity of fiberboard, the feeding mechanism required for fiberboard processing needs to be particularly concerned, and its structural characteristics and working effects also need to be designed and arranged to cope with various feeding situations.

[0004] Chinese Patent Authorization Publication Number: CN218641864U, Authorization Publication Date: March 17, 2023, discloses an automatic feeding device for fiberboard drilling, including a lifting and rotating mechanism and a clamping mechanism. The clamping mechanism includes a rotating box and two clamping components. Sliding grooves are respectively formed on the opposite side walls of the rotating box, and the two clamping components are respectively arranged corresponding to the sliding grooves on both sides. The clamping component includes a driving member and two moving plates. The two moving plates are arranged in the same sliding groove. A supporting plate is installed at the bottom of the moving plate. The driving member is installed in the rotating box and can drive the two moving plates to approach each other to clamp the limiting plate. The lifting and rotating mechanism includes a telescopic member, a base and a supporting plate arranged in parallel. A driving motor is installed on the supporting plate, and the output shaft of the driving motor is fixedly connected to the bottom of the rotating box. The telescopic member is fixedly installed between the base and the supporting plate. The disadvantage of this technical solution is that during the feeding work of the fiberboard, when extracting and placing the fiberboard, it is carried out under the control of the telescopic member. This telescopic member can be any one of a hydraulic cylinder, a pneumatic cylinder, and an electric push rod. However, the telescopic working content of the telescopic member is not disclosed in detail, nor is it stated that there is a telescopic component on the supporting plate. In this way, it is impossible to clearly understand how the supporting plate moves up and down through the telescopic member. Of course, it is also impossible to ensure the stability of the supporting plate during movement. In this case, when the supporting plate moves up and down, the conveying device for limiting the fiberboard may be separated from the support, resulting in inconvenient conveying of the fiberboard.

[0005] In summary, a structure can be set to enable the conveying component of the fiberboard to move up and down smoothly under the support effect. Summary of the Utility Model

[0006] The present utility model aims to overcome the deficiency in the prior art that there is no stable structure for the up and down movement of the supporting plate, and provides an automatic feeding mechanism for fiberboard processing that can enable the limiting plate to move up and down under a stable supporting effect.

[0007] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0008] An automatic feeding mechanism for fiberboard processing, comprising a conveying frame and a support plate. A conveying hole is provided on the conveying frame, and a conveyor belt is installed on the conveying frame. The lengths of the front and rear ends of the conveyor belt are greater than the lengths of the front and rear ends of the conveying frame. The conveyor belt is matched with the conveying hole, and the conveyor belt is detachably connected to the conveying frame. Two rotating shafts are installed on the conveyor belt, and the two rotating shafts are respectively placed at the front and rear ends of the conveyor belt. The rotating shafts are sleeved on the inner surface of the conveyor belt. A number of limiting tubes are installed on the support plate. A telescopic hole is provided at the top of the limiting tube. A micro servo motor and a telescopic rod are installed on the limiting tube. The telescopic rod is placed at the telescopic hole. A rolling bearing is installed at the top of the telescopic rod. The two ends of the rotating shaft are respectively connected to the two rolling bearings. A telescopic groove is provided at the bottom end of the telescopic rod. A first thread is provided in the telescopic groove. The micro servo motor is placed inside the bottom end of the limiting tube. A telescopic shaft is installed on the micro servo motor. A second thread is provided on the telescopic shaft. The second thread is matched with the first thread.

[0009] Such a design can install a feeding mechanism through the conveying rack and the support plate. There are conveying holes on the conveying rack, and the conveyor belt on the conveying rack matches the conveying holes. In other words, the conveyor belt can pass through the conveying holes. In this way, the front and rear ends of the conveyor belt are respectively outside the front and rear ends of the conveying holes. Of course, the lengths of the front and rear ends of the conveyor belt are greater than the lengths of the front and rear ends of the conveying rack, which is a structural design that ensures the front and rear ends of the conveyor belt are placed outside the conveying holes. The conveyor belt and the conveying rack are detachably connected, so that the conveyor belt can rotate under the support of the conveying rack, that is, it can convey the items placed on the conveyor belt (here referring to fiberboard). At the same time, two rotating shafts are installed on the conveyor belt. The two rotating shafts are respectively placed at the front and rear ends of the conveyor belt, and the rotating shafts are sleeved on the inner surface of the conveyor belt. In this way, the conveyor belt can rotate under the support of the two rotating shafts. It can not only move the items on the conveyor belt, but also stretch the conveyor belt by the two rotating shafts, so that the fiberboard can be stably placed on the conveyor belt for conveying. In addition, several limiting tubes are installed on the support plate. There are telescopic holes at the top of the limiting tubes, and the telescopic rods are placed at the telescopic holes. A rolling bearing is installed at the top of the telescopic rod. The two ends of the rotating shaft are respectively connected to the two rolling bearings. The bottom end of the telescopic rod is provided with a telescopic groove, and a first thread is provided in the telescopic groove. A micro servo motor is placed inside the bottom end of the limiting tube. The telescopic shaft installed on the micro servo motor is provided with a second thread, and the second thread matches the first thread. That is, the work of the micro servo motor can drive the telescopic shaft to rotate. With the cooperation of the second thread of the telescopic shaft and the first thread of the telescopic groove, the telescopic rod can stably move up and down. Of course, the micro servo motor can control the telescopic shaft to rotate clockwise or counterclockwise. That is, the up and down movement of the telescopic rod is controlled by the micro servo motor. Then the rolling bearing also moves up and down under the drive of the telescopic rod, driving the conveyor belt supported by the rotating shaft to move up and down, that is, driving the items on the conveyor belt to move up and down stably. In this way, through the work of the conveyor belt, rotating shaft, rolling bearing, telescopic rod and micro servo motor in the limiting tube, the purpose of setting the limiting plate to move up and down under a stable support effect is achieved. Of course, the setting of the first thread in the telescopic groove and the setting of the second thread on the telescopic shaft are the structural layouts for the stable up and down movement of the items.

[0010] Preferably, the rolling bearing includes an inner ring and an outer ring. The outer ring is connected to the telescopic rod, and the rotating shaft is connected to the inner ring of the rolling bearing. Such a design, by connecting the outer ring of the rolling bearing to the telescopic rod and connecting the rotating shaft to the inner ring of the rolling bearing, enables the rotating shaft to rotate under the support of the telescopic rod. That is, the support effect and rotation work of the conveyor belt do not affect each other, being stable and reliable.

[0011] Preferably, two through holes are provided on the conveying rack, and the two through holes are symmetrically distributed at the left and right ends of the conveying rack. A rotating shaft and a servo motor are installed on the conveying rack. The rotating shaft is sleeved in the conveyor belt, and the two rotating shafts are symmetrically distributed with the rotating shaft as the center. The two ends of the rotating shaft respectively pass through the two through holes and are placed at the outer ends of the conveying rack. A servo motor shaft is installed on the servo motor, and a rotating belt is installed on the servo motor shaft. The rotating shaft is connected to the servo motor shaft through the rotating belt. With this design, by providing two through holes on the conveying rack, the two through holes are symmetrically distributed at the left and right ends of the conveying rack, and the rotating shaft is not only sleeved in the conveyor belt, but also its two ends respectively pass through the two through holes and are placed at the outer ends of the conveying rack. Of course, a servo motor shaft is installed on the servo motor, and a rotating belt is installed on the servo motor shaft, and the rotating shaft can be connected to the servo motor shaft through the rotating belt. Then, under the operation of the servo motor, the rotation of the servo motor shaft can drive the rotation of the rotating shaft, and the two rotating shafts are symmetrically distributed with the rotating shaft as the center. Then, the conveyor belt can be driven by the rotating shaft and smoothly rotate under the supporting effect of the rotating shafts to convey items.

[0012] Preferably, a plurality of retaining bars are installed on the conveying rack, and the plurality of retaining bars are symmetrically distributed at the front and rear ends of the conveying rack. The retaining bars are symmetric about the conveying hole from left to right. The front end of the retaining bar is connected to the conveying rack, and the distance between the rear ends of the front and rear symmetric retaining bars is greater than the distance between the two rotating shafts. The bottom end of the retaining bar is on the same plane as the outer surface of the conveyor belt, and the top end of the retaining bar is on the same plane as the top end of the conveying rack. With this design, by installing a plurality of retaining bars on the conveying rack, the plurality of retaining bars are symmetrically distributed at the front and rear ends of the conveying rack, and the retaining bars are symmetric about the conveying hole from left to right. The front end of the retaining bar is connected to the conveying rack, and the distance between the rear ends of the front and rear symmetric retaining bars is greater than the distance between the two rotating shafts. Then, the conveying rack can be controlled to place the plane of the outer surface of the conveyor belt on the conveying rack at the position for receiving the fiber board, so that the fiber board can be smoothly placed on the outer surface of the conveyor belt. Of course, the bottom end of the retaining bar is on the same plane as the outer surface of the conveyor belt, and the top end of the retaining bar is on the same plane as the top end of the conveying rack. In this way, the left and right ends of the conveyor belt can be blocked to reduce the probability of the fiber board detaching from the left and right ends of the conveyor belt during the conveying process. Finally, the conveying rack can be controlled to face the position for collecting the fiber board, and the fiber board can be smoothly moved to detach from the conveyor belt for collection.

[0013] Preferably, a rotating rod is installed on the support plate. The bottom end of the rotating rod is detachably connected to the support plate. A rotating groove is provided at the bottom end of the conveying frame, and the top end of the rotating rod is matched with the rotating groove. With this design, by installing the rotating rod on the support plate, the bottom end of the rotating rod is detachably connected to the support plate. The bottom end of the conveying frame is provided with a rotating groove, and the top end of the rotating rod is matched with the rotating groove. Thus, the rotating rod can rotate under the support of the support plate. When the top end of the rotating rod is inserted into the rotating groove, the rotation of the rotating rod can drive the rotation of the conveying frame, and naturally drive the rotation of the fiberboard on the conveyor belt. In this way, the rotation of the conveyor belt can be controlled to reach the position for receiving the fiberboard and the position for discharging the receiving plate, facilitating the receiving and collection of the fiberboard and enabling the smooth progress of the feeding and conveying work of the fiberboard.

[0014] Preferably, a motor is installed on the support plate. A motor shaft is installed on the motor. A rotating hole is provided on the support plate. The bottom end of the rotating rod is placed at the rotating hole, and the bottom end of the rotating rod is detachably connected to the motor shaft. With this design, by installing the motor on the support plate, the motor shaft is installed on the motor, and a rotating hole is provided on the support plate. The bottom end of the rotating rod is placed at the rotating hole, and the bottom end of the rotating rod is also detachably connected to the motor shaft. In this way, the operation of the motor can drive the rotation of the motor shaft. The rotation of the motor shaft can not only control the up and down movement of the rotating rod, but also drive the rotation of the rotating rod. In this way, even when the conveyor belt is in the up and down movement state, it can still be driven by the motor shaft to rotate. Then, the conveyor belt can be rotated to the position for receiving the fiberboard and discharging the fiberboard, and the receiving and discharging work of the fiberboard can be carried out at a suitable height.

[0015] Preferably, the bottom end of the motor shaft is connected to the motor. Several insertion holes are provided at the bottom end of the motor shaft. The several insertion holes are symmetrically distributed, and the distribution of the insertion holes is annular. Several insertion rods are installed at the bottom end of the rotating rod, and the insertion rods correspond to the insertion holes one by one. With this design, by connecting the bottom end of the motor shaft to the motor, several insertion holes are provided at the bottom end, and the several insertion holes are symmetrically distributed. The distribution of the insertion holes here is annular. Several insertion rods are installed at the bottom end of the rotating rod, and the insertion rods correspond to the insertion holes one by one. That is, the insertion rods can be aligned with the insertion holes. Then, when the rotating rod is driven by the support plate to move up and down, it can be carried out under the limiting effect of the insertion holes. In this way, no matter at which height the fiberboard on the support plate is, it can be rotated under the drive of the motor shaft.

[0016] The beneficial effects of the present utility model are: the purpose of enabling the limiting plate to move up and down under a stable supporting effect can be achieved; it is convenient to smoothly carry out the receiving and discharging work of the fiberboard; the probability of the fiberboard detaching from the left and right ends of the conveyor belt can be reduced.

[0025] As Figure 2 , Figure 3 and Figure 5As shown in the figure, there are two through holes 23 on the conveying rack 1. The two through holes 23 are symmetrically distributed at the left and right ends of the conveying rack 1. A rotating shaft 4 and a servo motor 6 are installed on the conveying rack 1. The rotating shaft 4 is sleeved inside the conveyor belt 3. The two rotating shafts 5 are symmetrically distributed with the rotating shaft 4 as the center. The two ends of the rotating shaft 4 respectively pass through the two through holes 23 and are located at the outer ends of the conveying rack 1. A servo motor shaft 7 is installed on the servo motor 6, and a rotating belt 8 is installed on the servo motor shaft 7. The rotating shaft 4 is connected to the servo motor shaft 7 through the rotating belt 8. A number of retaining bars 16 are installed on the conveying rack 1. The number of retaining bars 16 are symmetrically distributed at the front and rear ends of the conveying rack 1. The retaining bars 16 are symmetric about the conveying hole 2 from left to right. The front end of the retaining bar 16 is connected to the conveying rack 1. The distance between the rear ends of the symmetrically distributed retaining bars 16 in the front and rear is greater than the distance between the two rotating shafts 5. The bottom end of the retaining bar 16 and the outer surface of the conveyor belt 3 are on the same plane. The top end of the retaining bar 16 and the top end of the conveying rack 1 are on the same plane. A rotating rod 20 is installed on the support plate 17. The bottom end of the rotating rod 20 is detachably connected to the support plate 17. A rotating groove 19 is provided at the bottom end of the conveying rack 1. The top end of the rotating rod 20 matches the rotating groove 19. A motor 21 is installed on the support plate 17. A motor shaft 22 is installed on the motor 21. A rotating hole 18 is provided on the support plate 17. The bottom end of the rotating rod 20 is located at the rotating hole 18. The bottom end of the rotating rod 20 is detachably connected to the motor shaft 22. The bottom end of the motor shaft 22 is connected to the motor 21. A number of jacks 25 are provided at the bottom end of the motor shaft 22. The number of jacks 25 are symmetrically distributed. The distribution of the jacks 25 is annular. A number of inserting rods 24 are installed at the bottom end of the rotating rod 20. The inserting rods 24 correspond to the jacks 25 one by one.

[0026] First, install the automatic feeding mechanism for fiberboard processing, that is, install the conveying rack 1, the support plate 17, the motor 21 and the components above. Of course, the motor 21, the micro servo motor 13 and the servo motor 6 installed on the automatic feeding mechanism need to be electrically connected to the external switch assembly, and the switch assembly needs to be electrically connected to the external power supply, so as to provide power for the operation of the motor 21, the micro servo motor 13 and the servo motor 6.

[0027] Next, place the automatic feeding mechanism on a plane. Generally, the bottom end of the motor 21 is placed on the plane, and the motor shaft 22 is installed at the top end of the motor 21. The conveyor belt 3 is located between the receiving fiberboard and the discharging fiberboard. Generally, the output end of the fiberboard can be a mechanical conveyor belt, and the collecting end of the fiberboard can be a collecting plate. The conveyor belt 3 is placed between the conveyor belt and the collecting plate. Of course, there may be a height difference between the conveyor belt, the collecting plate, and the conveyor belt 3. In this case, it is necessary to control through the switch assembly to make the micro servo motor 13 inside the bottom end of the limit tube 9 work, that is, drive the rotation of the telescopic shaft 14 installed on the micro servo motor 13. There is a second thread on the telescopic shaft 14, and a telescopic groove 15 is provided at the bottom end of the telescopic rod 10 installed at the telescopic hole 12 at the top end of the limit tube 9. A first thread is provided on the telescopic groove 15, and the second thread matches the first thread. That is, with the rotation of the telescopic shaft 14, under the cooperation of the second thread and the first thread, the telescopic rod 10 is controlled to move. The micro servo motor 13 can control the telescopic shaft 14 to rotate clockwise or counterclockwise, and the telescopic rod 10 can be controlled to move up or down, that is, the rolling bearing 11 at the top end of the telescopic rod 10 can be controlled to move up and down. Of course, the rolling bearing 11 here includes an inner ring and an outer ring. The outer ring is connected to the telescopic rod 10, and the rotating shaft 5 is connected to the inner ring. In other words, the conveyor belt 3 sleeved with the rotating shaft 5 can be controlled to move up and down until it is adjusted to a height convenient for receiving or discharging the fiberboard.

[0028] Moreover, the bottom end of the motor shaft 22 is connected to the motor 21, and several jacks 25 are provided at the bottom end. The several jacks 25 are symmetrically distributed and are distributed in a ring shape. Several inserting rods 24 are installed at the bottom end of the rotating rod 20, and the inserting rods 24 correspond to the jacks 25 one by one. A rotating groove 19 is provided at the bottom end of the conveying frame 1, and the top end of the rotating rod 20 matches the rotating groove 19. A third thread can be provided at the rotating groove 19, and a fourth thread can be provided at the top end of the rotating rod 20. Connect the top end of the rotating rod 20 to the conveying frame 1 through the cooperation of the third thread and the fourth thread. In this way, under the drive of the conveying frame 1, the rotating rod 20 can move up and down. However, the up and down movement of the rotating rod 20 is always carried out under the limiting effect of the inserting rod 24 in the jack 25, only the depth of the inserting rod 24 inserted into the jack 25 is different.

[0029] In the work of receiving fiberboards, under the control of the switch assembly, the servo motor shaft 7 can rotate counterclockwise. Then, the rotating shaft 4 connected to the servo motor shaft 7 by the rotating belt 8 is also driven to rotate counterclockwise. The conveyor belt 3 is sleeved on the rotating shaft 4, so the conveyor belt 3 is also driven to rotate counterclockwise. It should be noted that a rack can be installed on the inner surface of the conveyor belt 3 here, and gears can be sleeved on both the rotating shaft 4 and the rotating shaft 5 to make the gears mesh with the rack, so that the driving rotation of the conveyor belt 3 proceeds smoothly. Of course, a number of stop bars 16 are also installed on the conveying rack 1. The number of stop bars 16 is symmetrically distributed at the front and rear ends of the conveying rack 1. The stop bars 16 are symmetric about the conveying hole 2 from left to right. The front end of the stop bar 16 is connected to the conveying rack 1. The distance between the rear ends of the front and rear symmetric stop bars 16 is greater than the distance between the two rotating shafts 5. The bottom end of the stop bar 16 and the outer surface of the conveyor belt 3 are on the same plane, and the top end is on the same plane as the top end of the conveying rack 1. In this way, the fiberboard can be placed on the conveyor belt 3 and move during the rotation of the conveyor belt 3 until it moves to the conveying hole 2 of the conveying rack 1 and is blocked by the conveying rack 1. The working effect of the stop bar 16 is to reduce the probability of the fiberboard detaching from the left and right ends of the conveyor belt 3 during movement.

[0030] Next, it is necessary to carry out the external discharge of the fiberboard. At this time, under the control of the switch assembly, the motor shaft 22 on the motor 21 can be rotated, thereby controlling the rotation of the rotating rod 20, that is, controlling the rotation of the conveying rack 1 and making the conveyor belt 3 on the conveying rack 1 rotate until it is aligned with the collecting plate. Then, the servo motor shaft 7 can be controlled to rotate clockwise. In this way, the fiberboard placed on the conveyor belt 3 can be controlled to move and finally detach from the conveyor belt 3 and move onto the collecting plate to carry out the processing work of the fiberboard. In this way, the automatic feeding work of a fiberboard processing is completed. Through the work of the conveyor belt 3, the rotating shaft 5, the rolling bearing 11, the telescopic rod 10, and the micro servo motor 13 in the limiting tube 9, the purpose of setting the limiting plate to move up and down under a stable supporting effect is achieved.
