Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically a bending machine with a bending protective plate. Background Technology

[0002] A curved conveyor with a bending guard plate is a device specifically designed to guide and protect items at bends in the conveyor line, ensuring a smooth and safe turn. During the conveying process, the guard plate acts like a "wall," physically restraining the items and forcing them to move along the centerline of the curved track, ensuring they do not deviate from the correct path. (Prior art: Authorization publication number CN213111116) U's patent discloses a packaging box conveyor curve and its guardrail device, including a frame, an inlet conveyor belt, a middle conveyor belt, an outlet conveyor belt, a left guardrail, and a right guardrail. The inlet, middle, and outlet conveyor belts are sequentially connected and installed on the frame, and are conveyed by their respective independent conveyor motors. The left and right guardrails are matched and installed on the frame. Although the distance between the handle plates can be adjusted to limit the goods during use, the height of the handle plates is fixed. The fixed vertical handle plates will increase the effective profile of the equipment. During non-production hours, personnel, forklifts, or other equipment moving in the workshop will come into contact with and collide with the handle plates, thereby damaging the handle plates and reducing their protective effect. Therefore, we propose a curve machine with a bending guardrail. Summary of the Invention

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-7This embodiment provides a technical solution: a bending machine with a bending protective plate, including a mounting frame 1, a conveyor frame 3 at the upper end of the mounting frame 1, conveyor rollers 10 rotatably connected inside the conveyor frame 3, and a protective mechanism 4; Protective mechanism 4 includes a fixed base 42, a transmission plate 43, a drive plate 44, and a protective plate 48. The fixed base 42 is located in the middle of the bottom wall of the mounting frame 1. The front and rear sides of the upper end of the fixed base 42 are rotatably connected to the transmission plate 43. The middle of the upper end of each of the two sets of transmission plates 43 is provided with a drive plate 44. The front and rear sides of the conveyor frame 3 are provided with protective plates 48. The drive assembly drives the two sets of fixed bases 42 to move. At this time, the distance between the two sets of mounting bases 46 will gradually decrease, so that the transmission plate 43 and the drive plate 44 drive the protective plate 48 to move upward. Through the cooperation of the transmission plate 43 and the drive plate 44, the protective plate 48 can be moved. When in use, the position of the protective plate 48 can be adjusted according to the height of the goods. When not in use, it can be folded up, further reducing the height of the bending machine with the bending protective plate, reducing the floor space, and solving the problem of damage to the protective plate 48 caused by collision between external equipment and the protective plate 48.

[0017] It also includes a controller 2, which is located outside the mounting bracket 1. The input terminal of the controller 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0018] The protective mechanism 4 includes an adjusting plate 41, an adjusting seat 45, a mounting seat 46, and a mounting rod 47. The adjusting plate 41 is located in the middle between the ends of the two sets of protective plates 48 that are close to the center of the inside of the conveyor frame 3. The adjusting seat 45 is located in the middle of the lower end of the adjusting plate 41. The upper ends of the two sets of drive plates 44 are rotatably connected to the front and rear sides of the lower end of the adjusting seat 45, respectively. The mounting rod 47 is rotatably connected to the middle of the upper end of the transmission plate 43. The drive plate 44 is rotatably connected to the outside of the two sets of mounting rods 47. The mounting seat 46 is located in the middle of the outer arc surface of the two sets of mounting rods 47. The two sets of drive plates 44 are located between the outer surface of the vertically adjacent mounting seats 46 and the inner wall of the transmission plate 43, respectively. The adjusting seat 45 will drive the protective plate 48 to move upward through the adjusting plate 41.

[0019] The protective mechanism 4 also includes a screw 49, which is rotatably connected to the middle of the rear end of the front mounting seat 46. The rear mounting seat 46 is threaded to the rear side of the outer arc surface of the screw 49 through a threaded hole in the middle of its front end. During rotation, the screw 49 will drive the rear mounting seat 46 to move forward through the threaded connection. At the same time, the screw 49 will also drive the front mounting seat 46 to move backward.

[0020] The screw 49 has a drive seat 7 at its front end and a socket at the middle of the right end of the drive seat 7. The operator inserts an external rocker arm into the socket, and then the rocker arm drives the drive seat 7 to rotate through the socket. The drive seat 7 then drives the screw 49 to rotate.

[0021] The system also includes a bellows 8 and a fixing cylinder 9. The bellows 8 is located between the opposite inner surfaces of the two sets of mounting seats 46. The bellows 8 is sleeved on the middle of the outer arc surface of the screw 49. A fixing cylinder 9 is located in the middle of the rear end of the mounting seat. The rear end of the screw 49 is located inside the fixing cylinder 9. The distance between the two sets of mounting seats 46 will gradually decrease, the bellows 8 will shrink, and the fixing cylinder 9 will extend. The bellows 8 and the fixing cylinder 9 can prevent the screw 49 from having direct contact with the external environment.

[0022] The conveyor frame 3 has uprights 5 on the left and right sides of its top wall. Each of the four sets of uprights 5 has a baffle at its lower end. The two sets of protective plates 48 are connected by connecting plates 6 on the left and right sides of the end closest to the center of the conveyor frame 3. The upper ends of the two longitudinally adjacent sets of uprights 5 are slidably connected to the corresponding sliding holes at the lower ends of the connecting plates 6. The transmission plate 43 and the drive plate 44 provide an upward thrust to the adjusting seat 45. The adjusting seat 45 will drive the protective plate 48 to move upward along the uprights 5 through the adjusting plate 41.

[0023] The system also includes a laser rangefinder 11, which is located in the middle of the upper part of the connecting plate 6 on the right side. The laser rangefinder 11 corresponds to the upper and lower positions of the conveyor frame 3. The laser rangefinder 11 is bidirectionally electrically connected to the controller 2. During use, the laser rangefinder 11 emits a laser beam to the lower end of the conveyor frame 3 through its built-in light source. When the laser beam comes into contact with the lower end of the conveyor frame 3, it is reflected. The laser rangefinder 11 then receives the reflected light. By measuring the round-trip time of the laser beam, the laser rangefinder 11 calculates the distance between the upper end of the laser rangefinder 11 and the lower end of the conveyor frame 3.

[0024] The working principle of the bending machine with bending protective plate provided by this utility model is as follows: Before installing the conveyor roller 10, a sprocket is first installed at the rear end of the conveyor roller 10. Then, the conveyor roller 10 is installed inside the conveyor frame 3. A drive motor is then installed on the left side of the rear end of the conveyor frame 3 by a bolt. The output shaft of the drive motor is connected to the rear end of the leftmost conveyor roller 10 using a coupling. Then, two sets of sprockets that are laterally adjacent are connected by a chain. After that, the goods to be moved are placed on the upper side of the left conveyor roller 10. Then, the height of the goods to be moved and the distance between the upper side of the outer arc surface of the conveyor roller 10 and the upper surface of the conveyor frame 3 are measured, such as a and b. When the bending machine with bending protective plate is not in use, the upper end of the protective plate 48 is connected to the conveyor roller 3. The upper end of the conveyor frame 3 is flush with the lower end. Then, the distance between the upper end of the laser rangefinder 11 and the lower end of the conveyor frame 3 is measured. During use, the laser rangefinder 11 emits a laser beam to the lower end of the conveyor frame 3. The laser beam reflects upon contact with the lower end of the conveyor frame 3, and the laser rangefinder 11 receives the reflected light. By measuring the round-trip time of the laser beam, the laser rangefinder 11 calculates the distance between the upper end of the laser rangefinder 11 and the lower end of the conveyor frame 3, denoted as c. The laser rangefinder 11 then transmits the detected information to the controller 2 via its built-in data transmission module. The controller 2 receives the detected data through its built-in serial communication port and then subtracts the distance between the upper side of the outer arc surface of the conveyor roller 10 and the lower end of the conveyor frame 3 from the height of the goods. The distance between the upper surfaces of the conveyor frame 3, plus the distance between the upper end of the laser rangefinder 11 and the lower end of the conveyor frame 3, gives the distance between the upper end of the laser rangefinder 11 and the lower end of the conveyor frame 3 when the upper end of the protective plate 48 is flush with the upper end of the goods. Let's call this 'd', where d = a - b + c. Then, the operator inserts the external rocker arm into the socket, which drives the drive seat 7 to rotate through the socket. The drive seat 7 drives the screw 49 to rotate. During rotation, the screw 49 drives the rear mounting seat 46 forward through the threaded connection. At the same time, the screw 49 also moves the front mounting seat 46 backward. At this time, the distance between the two sets of mounting seats 46 gradually decreases, the bellows 8 contracts, and the bellows 8 and the fixed cylinder... 9 prevents the screw 49 from directly contacting the external environment. A fixed cylinder 9 is connected to the middle of the rear end of the mounting base 46 via bolts and a flange. The length of the fixed cylinder 9 is one-third of the screw 49. A limit plate is provided at the right end of the screw 49 to prevent the screw 49 from separating from the rear mounting base 46. This also prevents excessive retraction of the transmission plate 43 and drive plate 44, which could cause the fixed cylinder 9 to contact the rear wall of the mounting frame 1. During the movement of the two sets of mounting bases 46, the transmission plate 43 and drive plate 44 provide an upward thrust to the adjusting seat 45. The adjusting seat 45, through the adjusting plate 41, drives the protective plate 48 to move upward along the upright 5. When the distance between the upper end of the laser rangefinder 11 and the lower end of the conveyor frame 3 is equal to d...This means the height of the protective plate 48 is flush with the cargo. Then, through external control equipment, the external drive motor starts running, rotating the left conveyor roller 10. The left conveyor roller 10, through the cooperation of sprockets and chains, sequentially drives the right conveyor roller 10 to rotate. During the rotation of the conveyor rollers 10, the cargo is moved to the right, thus achieving the transportation of the cargo.

[0025] It is worth noting that, in the above embodiments, the laser rangefinder 11 can be HMLDM-UD100A, and the controller 2 controls the operation of the laser rangefinder 11 using methods commonly used in the prior art.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
