Description

Technical Field

[0001] This utility model relates to the technical field of bandage processing devices, specifically an automatic bandage flipping device. Background Technology

[0002] In the large-scale production process of medical and civilian bandages, "turning over" is a core process to ensure product safety, functionality and compliance. It solves problems such as rough edge irritation, concealment of processing marks, liquid absorption and optimization of elasticity. Its operation efficiency and quality stability directly determine the capacity and product qualification rate of the entire production line. Although some large enterprises have introduced semi-automatic flipping equipment based on "mechanical grippers + conveyor belts", such equipment still has core technical defects. The equipment is mostly designed for bandages of a single specification (such as fixed width and thickness). When switching to produce bandages of different lengths and thicknesses (such as switching from 5cm wide gauze bandages to 15cm wide elastic bandages), manual disassembly and adjustment of the gripper spacing and positioning components are required. The adjustment cycle can take up to 2-4 hours, and the flipping failure is easily caused by adjustment errors. It cannot meet the current market's flexible production needs of "small batches and multiple varieties".

[0003] Therefore, an automatic bandage flipping device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic bandage flipping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic bandage flipping device includes a base, a support plate fixedly connected to the top of the base, an electrical control box fixedly connected to the outside of the support plate, a flipping mechanism disposed between the support plates, a bandage body installed inside the flipping mechanism, and an adjustment mechanism disposed on the top of the flipping mechanism. The flipping mechanism includes a rotating base, a rotating rod is rotatably engaged inside the rotating base, a connecting block is provided on the top of the base, a motor is fixedly connected to the outside of the connecting block, a rotating shaft is fixedly connected to the output end of the motor, and a clamping frame is fixedly connected to the outside of the rotating shaft and the rotating rod. The adjustment mechanism includes a stabilizing plate, a fixed plate is fixedly connected to the top end of the stabilizing plate, an electric telescopic rod is fixedly connected to the outside of the fixed plate, a push rod is fixedly connected to the output end of the electric telescopic rod, a moving block is fixedly connected to the outside of the push rod, a sliding groove is opened inside the stabilizing plate, and a connecting rod is fixedly connected to the bottom of the moving block.

[0006] As a further optimization of this utility model, the top of the clamping frame is fixedly connected to a threaded tube, the inside of the threaded tube is connected to a screw, and the bottom of the screw is fixedly connected to a positioning cover.

[0007] As a further optimization of this utility model, the support plates are fixed and symmetrically distributed at both ends of the top of the base, and the rotating seat is fixedly connected to the outside of one side of the support plate.

[0008] As a further optimization of this utility model, the rotating shaft traverses the interior of the connecting block, and the two clamping frames are on the same plane.

[0009] As a further optimization of this utility model, the stabilizing plate is fixedly connected to the top of the supporting plate, and the moving block is slidably connected to the top of the stabilizing plate.

[0010] As a further optimization of this utility model, the connecting rod is slidably connected inside the groove, and the bottom of the connecting rod is fixedly connected to the top of the connecting block.

[0011] As a further optimization of this utility model, the threaded tubes are symmetrically distributed on the top of the clamping frame, and the positioning cover is movably connected to the inside of the clamping frame via a screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the device uses a motor-driven rotating shaft to rotate the clamping frame. With the stable support of the rotating seat and rotating rod, it achieves automated operation of flipping the bandage body. Compared with traditional manual flipping, it greatly improves the flipping efficiency and can adapt to the continuous conveying rhythm of the production line. At the same time, the electric telescopic rod in the adjustment mechanism pushes the moving block to slide along the slide groove, driving the connecting block and the clamping frame to move as a whole. It can flexibly adjust the clamping position according to the length of different specifications of bandages, solving the problem of poor adaptability of existing equipment. It does not require frequent machine stops for adjustment and meets the flexible production needs of multiple types of bandages.

[0013] In this utility model, the threaded tube at the top of the clamping frame cooperates with the screw to drive the positioning cover to move up and down, which can closely fit the bandage body of different thicknesses, prevent the bandage from shifting or slipping during the flipping process, and ensure the flipping accuracy. Moreover, the overall structure is uniformly controlled by the electrical control box, reducing the risk of contamination from manual contact and lowering the product defect rate. At the same time, the stable connection between the support plate and the base and the symmetrical distribution design of each component ensure the stability of the device during operation, further guaranteeing the quality of the bandage after flipping, and meeting the compliance requirements for the production of medical and civilian bandages.

[0016] 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.

[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0018] Please see Figures 1-4 This utility model provides a technical solution: An automatic bandage flipping device includes a base 1, a support plate 2 fixedly connected to the top of the base 1, an electrical control box 3 fixedly connected to the outside of the support plate 2, a flipping mechanism 4 arranged between the support plates 2, a bandage body 5 installed inside the flipping mechanism 4, and an adjustment mechanism 6 arranged on the top of the flipping mechanism 4. The flipping mechanism 4 includes a rotating seat 41, a rotating rod 42 is rotatably engaged inside the rotating seat 41, a connecting block 43 is provided on the top of the base 1, a motor 44 is fixedly connected to the outside of the connecting block 43, a rotating shaft 45 is fixedly connected to the output end of the motor 44, and a clamping frame 46 is fixedly connected to the outside of the rotating shaft 45 and the rotating rod 42. The adjustment mechanism 6 includes a stabilizing plate 61, a fixing plate 62 fixedly connected to one top end of the stabilizing plate 61, an electric telescopic rod 63 fixedly connected to the outside of the fixing plate 62, a push rod 64 fixedly connected to the output end of the electric telescopic rod 63, a moving block 65 fixedly connected to the outside of the push rod 64, a sliding groove 66 opened inside the stabilizing plate 61, and a connecting rod 67 fixedly connected to the bottom of the moving block 65. It should be noted that: the support plates 2 are fixed and symmetrically distributed at both ends of the top of the base 1, the rotating seat 41 is fixedly connected to the outside of one side of the support plate 2, the rotating shaft 45 passes through the inside of the connecting block 43, the two clamping frames 46 are on the same plane, the stabilizing plate 61 is fixedly connected to the top of the support plate 2, the moving block 65 is slidably connected to the top of the stabilizing plate 61, the connecting rod 67 is slidably connected to the inside of the slide groove 66, and the bottom of the connecting rod 67 is fixedly connected to the top of the connecting block 43.

[0019] Furthermore, the base 1 and support plate 2, as the basic support structure of the device, are made of Q235 cold-rolled steel plate. This material has high strength and good rigidity, and can withstand the radial and axial forces when the flipping mechanism 4 rotates, avoiding deformation after long-term use. At the same time, the surface is treated with electrophoretic anti-rust treatment, which can resist the corrosion of water vapor and dust in the production environment and extend the service life of the equipment. The rotating rod 42 and the rotating shaft 45, as key transmission components, are made of No. 45 quenched and tempered steel. Through quenching and tempering treatment, its hardness reaches HRC28-32, which ensures sufficient wear resistance and a certain degree of toughness. The surface of the rod is finely ground, with a roughness Ra≤0.8μm, reducing the fit clearance with the rotating seat 41 and the connecting block 43, and ensuring that the coaxiality error during rotation is ≤0.05mm.

[0020] Specifically: The main body of the clamping frame 46 is made of aluminum alloy profile, which is much lower than steel, thus reducing the load on the motor 44 and lowering energy consumption. It also has excellent corrosion resistance. The inner edges of the frame are rounded to avoid scratching the edges of the bandage body 5. The positioning cover 49 is made of food-grade silicone. Silicone has good elasticity and anti-slip properties, and can fit tightly to bandages of different thicknesses when pressed without leaving indentations on the surface of the bandage. At the same time, silicone has a wide temperature resistance range, which can adapt to the temperature fluctuations in the production workshop, and it is easy to clean, meeting the hygiene requirements for the production of medical bandages.

[0021] Meanwhile, the motor 44 is a servo motor, which can ensure that it stops precisely at 180° when flipping; it is also equipped with an electromagnetic braking function, which can immediately lock the rotating shaft 45 when the power is cut off to prevent the bandage from slipping due to gravity when the equipment stops unexpectedly. The electric telescopic rod 63 adopts a ball screw drive to ensure the accuracy of the position adjustment of the clamping frame 46.

[0022] As a further implementation of this solution, a threaded tube 47 is fixedly connected to the top of the clamping frame 46, a screw 48 is connected to the internal thread of the threaded tube 47, and a positioning cover 49 is fixedly connected to the bottom of the screw 48.

[0023] Furthermore, threaded tubes 47 are symmetrically distributed on the top of the clamping frame 46, and positioning covers 49 are movably connected to the inside of the clamping frame 46 via screws 48.

[0024] Specifically: The outer side of the threaded tube 47 at the top of the clamping frame 46 is marked with scale lines. When the operator rotates the screw 48, the operator can accurately control the downward movement distance of the positioning cover 49 according to the scale lines, so as to avoid uneven clamping force caused by differences in operator experience, ensure the consistency of the fixing effect of different batches of bandages, and reduce the product defect rate.

[0025] Work process: When the automatic bandage flipping device is working, the base 1 must first be fixed at the designated work station on the production line to ensure that the symmetrically distributed support plates 2 are perpendicular to the base 1. The specifications of the bandage body 5 to be processed are input through the electrical control box 3 on the outside of the support plate 2, and the flipping angle and stroke are set. At the same time, the power pre-start of the motor 44 and the electric telescopic rod 63 is completed. Then the operator lays the bandage body flat in the two clamping frames 46 of the flipping mechanism 4. Next, the control box 3 drives the electric telescopic rod 63, which pushes the push rod 64 fixed on the outside of the fixing plate 62 of the stabilizing plate 61 to move horizontally, causing the moving block 65 to slide on the top of the stabilizing plate 61. The connecting rod 67 at the bottom of the moving block 65 slides synchronously along the slide groove 66 of the stabilizing plate 61, thereby pulling the connecting block 43 and the motor 44 and the rotating shaft 45 on the outside to move, so that the clamping frame 46 on the outside of the rotating shaft 45 is adjusted to a position that matches the length of the bandage. After receiving the position sensor signal, the control box 3 controls the electric telescopic rod 63 to stop. The operator then rotates the screws 48 symmetrically distributed at the top of the clamping frame 46, and uses the threaded connection between the screws 48 and the threaded tube 47 to drive the flexible positioning cover 49 at the bottom to move vertically downward until it is tightly attached to the surface of the bandage and firmly fixed. Then, the control box 3 sends a signal to the motor 44. The output end of the motor 44 drives the rotating shaft 45 to rotate. The rotating shaft 45 passes through the connecting block 43 and is provided with stable support. The clamping frame 46 on the other side rotates and engages with the rotating seat 41 on the outside of the support plate 2 through the rotating rod 42, so that the two clamping frames 46 drive the fixed bandage to rotate synchronously along the horizontal axis. The control box 3 monitors the angle through the encoder. When the preset 180° is reached, the control box 3 controls the motor 44 to stop, completing the replacement of the inner and outer sides of the bandage. Finally, the operator rotates the screw 48 in the opposite direction to move the positioning cover 49 upward, removes the flipped bandage and passes it to the next process. At the same time, the control box 3 controls the electric telescopic rod 63 to run in the opposite direction, driving the moving block 65, connecting block 43 and clamping frame 46 to reset, waiting for the next batch of work. The whole process is coordinated by the control box 3 to achieve automated and precise flipping of the bandage.
