Description

Technical Field

[0001] The present application relates to the field of conveyors, and in particular to a front-end structure of a conveyor. Background Technique

[0002] A conveyor refers to a machine that continuously conveys bulk materials or packaged goods in a continuous manner along a certain line from a loading point to an unloading point. When the conveying machine is working, the goods are continuously conveyed along a certain line; the loading and unloading of the working components are both carried out during the movement process. The bulk goods being conveyed are continuously distributed on the conveyor belt, and the packaged goods being conveyed also move continuously in a certain order.

[0003] When the goods fall from the discharge port of the forming equipment onto the conveyor belt of the conveyor, the positions of the goods falling on the conveyor belt are different and cannot be arranged neatly and orderly. When conveyed to the next process, it is easy for some goods to shift when falling into the next processing position, affecting the processing effect.

[0004] The above information disclosed in this background technique is only used to increase the understanding of the background technique of the present application. Therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content

[0005] In order to solve the problem that the positions of the goods falling onto the conveyor belt are different and cannot be arranged neatly and orderly, and it is easy for some goods to shift when falling into the next processing position during the conveyance to the next process, the present application provides a front-end structure of a conveyor. The front-end structure of a conveyor provided by the present application adopts the following technical solution:

[0006] A front-end structure of a conveyor includes a conveying table. Above the upper edges on both sides of the conveying table, two fixing plates are symmetrically arranged. Above the two fixing plates, a mounting plate is provided in the middle. A bidirectional lead screw is rotatably connected between the two mounting plates. Above the side of one of the mounting plates, a driving motor is installed, and the output end of the driving motor is fixed to one end of the bidirectional lead screw. The two sides of the fixing plate are both penetrated by positioning rods. A sliding plate is installed between the two positioning rods. A transmission plate is installed in the middle of the sliding plate, and the top of the transmission plate is in screw transmission with the corresponding end of the bidirectional lead screw. A deviation-correcting plate is installed between the ends of the two positioning rods on the same side. A guide rail frame is installed between the two fixing plates. A driven limiting component is provided between the guide rail frame and the bidirectional lead screw.

[0007] Preferably, the driven limiting component includes a gear plate, a U-shaped tooth plate and a baffle. The gear plate is fixedly sleeved at the middle position of the bidirectional lead screw. The U-shaped groove of the U-shaped tooth plate is slidably connected to the middle position of the guide rail frame, and the side of the U-shaped tooth plate is meshed with the gear plate. A baffle is sleeved outside the U-shaped tooth plate.

[0008] Preferably, sliders are provided at both corners of the bottom of the U-shaped tooth plate, and the sliders penetrate through the rectangular slots opened on both sides of the baffle plate.

[0009] Preferably, the middle position of the guide rail frame is integrally formed into an I shape.

[0010] Preferably, buffer springs are elastically connected between the two ends of the same-side skateboard and the deviation rectifying plate, and the positioning rods penetrate through the inside of the buffer springs.

[0011] Preferably, a C-shaped cross frame is installed on the side of the two fixing plates facing away from the guide rail frame, and an infrared sensor is provided at the middle position of the C-shaped cross frame.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. By driving the bidirectional lead screw to rotate counterclockwise by the driving motor, the transmission plates on both sides drive the skateboard to move. Then, the skateboard cooperates with the positioning rod to push the deviation rectifying plate to move, so that the deviation rectifying plates on both sides move synchronously towards both sides of the workpiece, thereby pushing the workpiece to the center position of the conveyor belt of the conveying table, facilitating more accurate entry into the next processing position and improving the processing effect of the device on the workpiece.

[0014] 2. By rotating the bidirectional lead screw, the gear plate can also be driven to rotate, driving the U-shaped tooth plate and the baffle plate to move downward, so that the bottom of the baffle plate fits with the conveyor belt of the conveying table, facilitating temporary limiting of the workpiece during the deviation rectifying process, effectively limiting the workpiece between the two deviation rectifying plates, and facilitating subsequent more effective deviation rectification of the workpiece by the deviation rectifying plates.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings to provide a more detailed description of the present application.

[0021] An embodiment of the present application discloses a front-end structure of a conveyor. Referring to Figure 1 and Figure 2 as well as Figure 3 and Figure 4 , a front-end structure of a conveyor includes a conveying platform 1. The conveying platform 1 is mainly composed of a main body frame, a conveyor belt, and a motor, which cooperate to realize the conveying of the conveyor belt of the conveying platform 1. Above the two side edges of the conveying platform 1, two fixing plates 9 are symmetrically arranged. Above the two fixing plates 9, a mounting plate 3 is centered. A bidirectional lead screw 16 is rotatably connected between the two mounting plates 3. Above the side of one mounting plate 3, a driving motor 2 is installed, and the output end of the driving motor 2 is fixed to one end of the bidirectional lead screw 16, facilitating the control of the rotation of the bidirectional lead screw 16 by the driving motor 2. Through both sides of the fixing plate 9, positioning rods 13 are penetrated. Between the outer parts of the two positioning rods 13, a sliding plate 10 is installed. A transmission plate 15 is centered on the sliding plate 10, and the top of the transmission plate 15 is in screw transmission with the corresponding end of the bidirectional lead screw 16. Between the ends of the two positioning rods 13 on the same side, a deviation rectifying plate 11 is installed. A guide rail frame 8 is installed between the two fixing plates 9. When the output end of the driving motor 2 drives the bidirectional lead screw 16 to rotate counterclockwise, the two side transmission plates 15 move towards each other. Then, the two side transmission plates 15 drive the sliding plate 10 to move. Immediately afterwards, the sliding plate 10 cooperates with the positioning rods 13 to push the deviation rectifying plate 11 to move, causing the two side deviation rectifying plates 11 to move synchronously towards the two sides of the workpiece, thereby pushing the workpiece to the center position of the conveyor belt of the conveying platform 1.

[0022] Referring to Figure 1 and Figure 2 as well as Figure 3 , in this driven limiting assembly, it includes a gear plate 5, a U-shaped tooth plate 7, and a baffle 12. The gear plate 5 is fixedly sleeved in the middle position of the bidirectional lead screw 16. The U-shaped groove of the U-shaped tooth plate 7 is slidably connected to the middle position of the guide rail frame 8, and the side surface of the U-shaped tooth plate 7 is meshed with the gear plate 5. When the bidirectional lead screw 16 rotates, it can also synchronously drive the gear plate 5 to rotate. Then, the gear plate 5 drives the U-shaped tooth plate 7 and the baffle 12 to move downward, making the bottom of the baffle 12 fit with the conveyor belt of the conveying platform 1, facilitating the temporary limiting of the workpiece during the deviation rectifying process, effectively limiting the workpiece between the two deviation rectifying plates 11, facilitating the subsequent deviation rectifying plate 11 to more easily achieve effective deviation rectification of the workpiece. At the same time, the baffle 12 is sleeved outside the U-shaped tooth plate 7, so that after the baffle 12 fits on the conveyor belt of the conveying platform 1, the U-shaped tooth plate 7 can still move inside the baffle 12 along with the rotation of the gear plate 5, avoiding affecting the deviation rectifying process of the two side deviation rectifying plates 11 moving towards each other.

[0023] Referring to Figure 1 and Figure 3In this structure, sliders 17 are provided at the two corners of the bottom of the U-shaped tooth plate 7, and the sliders 17 penetrate the rectangular grooves on both sides of the baffle 12 to prevent the U-shaped tooth plate 7 from being separated from the baffle 12, so that the bottom of the U-shaped tooth plate 7 can drive the baffle 12 to move up, and the limit of the workpiece after correction can be released in time.

[0024] Reference Figure 3 In this structure, the guide rail frame 8 is integrally formed in an I-shape at the middle position to prevent the U-shaped tooth plate 7 from shaking left and right, thereby ensuring the stable longitudinal movement of the U-shaped tooth plate 7.

[0025] Reference Figure 1 and Figure 4 A buffer spring 14 is elastically connected between both ends of the same-side slide plate 10 and the correcting plate 11, and the buffer spring 14 is penetrated by the positioning rod 13. The lower surfaces of the slide plate 10 and the correcting plate 11 are in contact with the surface of the conveyor belt of the conveyor platform 1. This method can prevent the correcting plates 11 on both sides from excessively squeezing the workpiece and causing damage to the workpiece.

[0026] Reference Figure 1 In this structure, a 匚-shaped cross frame 6 is installed on the side of the two fixed plates 9 facing away from the guide frame 8, and an infrared sensor 4 is provided in the middle position of the 匚-shaped cross frame 6. The infrared sensor 4 can cooperate with the PLC controller to transmit the signal to the control end of the drive motor 2, and then the drive motor 2 receives the control command information to complete the startup. The control technology involved is the existing technology and will not be described in detail in this application document.

[0027] The implementation principle of the front end structure of a conveyor in the embodiment of the present application is:

[0028] When the conveyor table 1 conveys the falling workpiece to the position of the infrared sensor 4, its infrared sensor 4 senses the existence of the workpiece and transmits the signal to the control end of the drive motor 2 through the PLC controller. Then the drive motor 2 receives the control command information and starts. Then the output end of the drive motor 2 drives the bidirectional screw 16 to rotate counterclockwise, so that the transmission plates 15 on both sides move toward each other, and then the transmission plates 15 on both sides drive the slide plate 10 to move, and then the slide plate 10 cooperates with the positioning rod 13 to push the correcting plate 11 to move, so that the correcting plates 11 on both sides move synchronously to the two sides of the workpiece, thereby pushing the workpiece to the center position of the conveyor belt of the conveyor table 1, which is convenient for entering the next processing position more accurately, and improving the processing effect of the device on the workpiece;

[0029] Meanwhile, when the bidirectional lead screw 16 rotates, it can also synchronously drive the gear plate 5 to rotate. Then, the gear plate 5 drives the U-shaped tooth plate 7 and the baffle 12 to move downward, so that the bottom of the baffle 12 is in contact with the conveyor belt of the conveying table 1, which is convenient for temporarily limiting the workpiece during the rectification process, effectively limiting the workpiece between the two rectification plates 11, and facilitating the subsequent rectification plates 11 to more easily achieve effective rectification of the workpiece. After the rectification of the workpiece is completed, the output end of the driving motor 2 drives the bidirectional lead screw 16 to rotate clockwise, releasing the limit on the workpiece, and then it can be transported to the next process.
