Abstract
Description
Technical Field
[0001] The utility model belongs to a packaging conveying device, in particular to a conveyor belt feeding bandwidth adjustment mechanism. Background Art
[0002] During the production process, carton-based packaging products, such as medicine boxes, are uniformly unloaded, sorted, and packaged on conveyor lines. For line workers, incoming carton-packed products must be located on the same side of the conveyor belt to facilitate fixed retrieving actions by the workers or the retrieving robot. However, since each batch of medicine boxes varies in size, they cannot remain in a uniform position upon arrival at the terminal without adjustment during transport. Existing mechanisms typically utilize a fixed retaining plate to adjust the incoming material. This retaining plate is fixed to the side panels with waist-shaped holes and secured with screws. Each adjustment requires manual operation by the worker. If the retaining plate is not adjusted correctly, it may become non-parallel to the conveyor belt. A skewed retaining plate can cause material jamming, affecting the conveying rhythm. Severe jamming can also cause "card punching," which can damage the entire retaining plate. Therefore, improvements to existing medicine box conveyor belts are needed. Utility Model Content
[0003] In response to the above problems and technical requirements, the utility model provides a conveyor belt feeding bandwidth adjustment mechanism. This mechanism can adjust the conveyor belt feeding bandwidth at the input end of the conveyor belt according to the different sizes of packaging boxes. The operation is simple and the operator does not need to repeatedly disassemble and install screws, which can avoid the problem of material jamming caused by inaccurate adjustment.
[0004] The technical solution of the present invention is as follows: a conveyor belt feeding bandwidth adjustment mechanism includes a base, a conveyor belt frame, a conveyor belt and a side push feeding mechanism, a conveyor belt frame is fixedly installed on the base, a conveyor belt frame is provided on the conveyor belt frame, the front end of the conveyor belt frame receives the boxes transmitted from the upstream, and the conveyor belt transmits the boxes to the rear; a side push feeding mechanism is provided on the side of the conveyor belt frame, and the side push feeding mechanism includes a screw assembly and a baffle, the screw assembly drives the baffle to telescopically move perpendicular to the transmission direction, the baffle always remains parallel to the transmission direction, and the baffle adjusts the material receiving bandwidth of the front section of the conveyor belt frame by telescoping; one end of the baffle extends from the front end of the conveyor belt frame, and when the box enters the conveyor belt, the baffle limits one side of the box, and the baffle occupies part of the bandwidth, and the box is only transmitted backward within the bandwidth space between the baffle and the opposite side of the conveyor belt frame. In this solution, by setting the screw assembly, the baffle can be driven to telescopically adjust, and the baffle always remains parallel to the transmission direction, and there will be no jamming due to non-parallel adjustment.
[0005] Furthermore, the screw assembly includes a vertical mounting plate, a slide rod, a screw rod, a nut moving block, and a U-shaped bracket. The vertical mounting plate is fixedly connected to the side of the conveyor belt frame. A bearing seat is installed on the back of the vertical mounting plate. One end of the screw rod is rotatably connected to the bearing seat. Slide rods are provided in parallel on both sides of the screw rod. One end of the slide rod is connected to the bearing seat. The other ends of the slide rod and the screw rod are simultaneously connected to a fixed block. The nut moving block is simultaneously connected to the screw rod and the two slide rods. The U-shaped bracket is connected to the nut moving block. The rotation of the screw rod drives the nut moving block to move back and forth, and the nut moving block drives the U-shaped bracket to move telescopically perpendicular to the conveying direction. The U-shaped bracket can support the entire baffle. As long as the baffle and the U-shaped bracket are stably connected, the telescopic movement of the baffle can be achieved through the synchronous movement of the U-shaped bracket and the nut moving block. The baffle does not need to be connected and adjusted in sections, which avoids the misalignment caused by section adjustment.
[0006] Furthermore, the middle part of the U-shaped bracket is fixedly connected to the nut moving block by screws, and the two arms of the U-shaped bracket extend forward from both sides of the vertical mounting plate respectively. The two arms of the U-shaped bracket are equal in length, and the front ends of the two arms are fixedly connected to the baffle bar by screws respectively. The baffle bar is arranged above the conveyor belt surface parallel to the conveyor belt, and the width of the baffle bar blocking the conveyor belt is consistent throughout its entire length, and the vertical mounting plate limits the baffle bar.
[0007] Furthermore, a handwheel is mounted on the outer surface of the fixed block and connected to the end of the screw. Rotating the handwheel drives the screw, which in turn drives the nut moving block and the U-shaped bracket to move. Using the handwheel to drive the screw, the U-shaped bracket and the barrier bar move simultaneously. This makes adjustment easier for the operator and enables continuous adjustment of the bandwidth, providing more precise control over the conveying bandwidth of the boxes.
[0008] Furthermore, a material-incoming baffle is fixedly provided on the side of the conveyor frame on the opposite side of the baffle bar. The front end of the material-incoming baffle extends beyond the front end of the conveyor frame, is higher than the surface of the conveyor belt, and is no less than the length of the baffle bar. The material-incoming baffle can block the boxes from this side, preventing the boxes from sliding to the other side due to excessive force and falling due to the obstruction of the baffle bar.
[0009] Furthermore, a set of beveled edges are correspondingly provided on the inner sides of the front ends of the baffle bar and the incoming material baffle plate, so as to guide the box parts into the space between the baffle bar and the incoming material baffle plate, thereby preventing the box parts from being damaged by sharp edges.
[0010] Furthermore, a height-limiting material receiving frame is provided at the front end of the conveyor belt frame, and the two side surfaces of the height-limiting material receiving frame are connected to the two sides of the conveyor belt frame. The top surface of the height-limiting material receiving frame is flat, and the baffle and the incoming material baffle are both covered in the height-limiting material receiving frame. The height-limiting material receiving frame can limit the height of the boxes entering the conveyor belt.
[0011] The beneficial effects of the present invention are: 1) easy to operate, and a single hand wheel is used to drive the U-shaped bracket and the baffle to extend and retract synchronously, which can be conveniently adjusted according to the size of the box. There is no need to repeatedly disassemble and assemble the baffle, which simplifies the adjustment process of the transmission bandwidth and effectively improves the transmission efficiency; 2) A U-shaped bracket with two arms of equal length is used to fix the baffle at the front end. The middle part of the U-shaped bracket is connected to the screw assembly. The U-shaped bracket itself can maintain horizontal stability. The baffle is fixedly connected to the two ends of the U-shaped bracket by screws. The baffle can also remain stable and always parallel to the transmission direction. There will be no slippage during the extension and retraction of the baffle, so that the distance between the baffle and the incoming baffle is always consistent, avoiding the phenomenon of material jamming and making the transmission and feeding more stable.

DETAILED DESCRIPTION
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1-3 The figure shows the conveyor belt feeding bandwidth adjustment mechanism of the present invention, which includes a base 1, a conveyor belt frame 2, a conveyor belt 3 and a side push feeding mechanism 4. The conveyor belt frame 2 is fixedly mounted on the base 1, and the conveyor belt frame 2 is provided with a conveyor belt 3. The front end of the conveyor belt frame 2 receives the boxes from the upstream, and the conveyor belt 3 transports the boxes to the rear; the side of the conveyor belt frame 2 is provided with a side push feeding mechanism 4, and the side push feeding mechanism 4 includes a screw rod assembly 5 and a baffle 6. The screw rod assembly 5 drives the baffle 6 to telescopically move perpendicular to the conveying direction, and the baffle 6 always remains parallel to the conveying direction. The baffle 6 adjusts the width of the material receiving bandwidth of the front section of the conveyor belt frame 2 by telescoping.
[0018] The screw rod assembly 5 includes a vertical mounting plate 51, a slide rod 52, a screw rod 53, a nut moving block 54 and a U-shaped bracket 55. The vertical mounting plate 51 is fixedly connected to the side of the conveyor belt frame 2. A bearing seat 56 is installed on the back of the vertical mounting plate 51. One end of the screw rod 53 is rotatably connected to the bearing seat 56. Slide rods 52 are provided in parallel on both sides of the screw rod 53. One end of the slide rod 52 is connected to the bearing seat 56. The other ends of the slide rod 52 and the screw rod 53 are simultaneously connected to a fixed block 57. The nut moving block 54 is simultaneously connected to the screw rod 53 and the two slide rods 52. The U-shaped bracket 55 is connected to the nut moving block 54. The rotation of the screw rod 53 drives the nut moving block 54 to move back and forth, and the nut moving block 54 drives the U-shaped bracket 55 to telescopically move perpendicular to the conveying direction. The middle portion of the U-shaped bracket 55 is screwed to the nut moving block 53. The two arms of the U-shaped bracket 55 extend forward from either side of the vertical mounting plate 51. The arms are of equal length, and their front ends are screwed to a stop bar 6. The stop bar 6 is positioned above and parallel to the conveyor belt 3, providing a consistent width of coverage across its entire length. The vertical mounting plate 51 limits the stop bar. A handwheel 58 is mounted on the outer surface of the fixed block 57. This handwheel 58 is connected to the end of the screw rod 53. Rotating the handwheel 58 drives the screw rod 53, which in turn drives the nut moving block 54 and the U-shaped bracket 55.
[0019] One end of the baffle 6 extends beyond the front end of the conveyor belt frame 2. As the boxes enter the conveyor belt 3, the baffle 6 limits the box's position on one side, occupying part of the belt width. The boxes are only transported backward within the bandwidth space between the baffle 6 and the opposite side of the conveyor belt frame 2. A material inlet baffle 7 is fixedly provided on the side of the conveyor belt frame 2 opposite the baffle 6. The front end of the material inlet baffle 7 extends beyond the front end of the conveyor belt frame 2, is higher than the conveyor belt surface, and is no less than the length of the baffle 6. The material inlet baffle 7 can block the boxes from this side, preventing them from sliding to the other side due to the obstruction of the baffle 6 and causing them to fall due to excessive force. A set of beveled edges 61 are correspondingly provided on the inner sides of the front ends of the baffle 6 and the material inlet baffle 7. The beveled edges 61 guide the boxes into the space between the baffle 6 and the material inlet baffle 7, preventing them from being damaged by sharp edges.
[0020] The front end of the conveyor frame 2 is provided with a height-limited receiving frame 8, the two side surfaces of which are connected to the two sides of the conveyor frame 2. The top surface of the height-limited receiving frame 8 is flat, and the blocking bar 6 and the incoming material baffle 7 are both covered in the height-limited receiving frame 8. The height-limited receiving frame 8 can limit the height of the boxes entering the conveyor 3. When the boxes enter, they need to pass through the height-limited receiving frame 8 first. If the boxes are not placed correctly, the height-limited receiving frame 8 can move the boxes to lie down, so that the boxes enter the conveyor 3 in the same state. The corresponding height-limited receiving frame 8 can also be replaced according to the size of the boxes.
[0021] The application principle of the present utility model is as follows: when used for the first time, the baffle 6 is connected to the U-shaped bracket 55, and the U-shaped bracket 55 is leveled so that the baffle 6 remains parallel to the conveying direction. When used subsequently, it is only necessary to drive the baffle forward or backward by rotating the hand wheel 58 in the forward or reverse direction to adjust the spacing, so that the spacing between the baffle 6 and the incoming baffle 7 is adapted to the size of the box passing through, so as to limit the conveying position of the box and facilitate the line edge operation at the rear.

Any changes and substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
