Description

Technical Field

[0001] This utility model relates to the field of rust inhibitor production technology, specifically to an outer packaging device for rust inhibitor production. Background Technology

[0002] The core of rust inhibitor production is to produce chemical agents that can inhibit metal corrosion through reasonable formulation and precise process control. The key lies in the selection of raw materials, control of reaction conditions, and quality inspection. The production steps include material preparation, mixing and stirring, addition and reaction of auxiliary agents, filtration and purification, cooling and packaging, etc. Cooling and packaging involves cooling the material to room temperature, and after passing the test, dispensing it into sealed containers to avoid secondary contamination. Then, several containers are packed in corrugated cardboard boxes and sealed with tape. Finally, PP strapping is used to tie them to prevent loosening and deformation during transportation, while not damaging the cardboard box and inner packaging.

[0003] In the current technology, the reinforcement of the outer packaging of rust inhibitor production is achieved by using outer packaging equipment to bundle the corrugated cardboard boxes. The outer packaging equipment consists of a frame structure, a conveying structure, a bundling execution structure, and a control system. In actual use, corrugated cartons are fed onto the machine, the strapping mechanism operates and straps are applied to the cartons. Then, by rotating the cartons 90 degrees, the strapping mechanism operates again, forming two straps, one longitudinal and one transverse. During rotation, the rust inhibitor shifts to one side due to centrifugal force, causing the center of gravity of the corrugated carton to shift. This results in the second strapping deviating from the centerline of the carton, and the intersection of the two straps is not at the geometric center of the carton. Consequently, the straps are not perpendicular or centered, and the stress points on the carton are concentrated at the overlapping or offset sides of the straps, thus affecting the strength of the packaging. Therefore, an outer packaging device for rust inhibitor production is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an outer packaging device for rust inhibitor production. It features centered positioning and split-type rotation, solving the problem that when a corrugated carton is fed onto the machine, the strapping mechanism operates and straps are applied to the carton. Then, by rotating the carton 90 degrees, the strapping mechanism operates again, forming two straps (one longitudinal and one transverse). During rotation, the rust inhibitor shifts to one side due to centrifugal force, causing the carton's center of gravity to shift. This results in the second strapping deviating from the carton's centerline, and the intersection of the two straps not being at the carton's geometric center. Consequently, the straps are not perpendicular or centered, and the stress on the carton is concentrated at the overlapping or offset sides of the straps, thus affecting the packaging strength.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an outer packaging equipment for the production of rust inhibitors, comprising two tables disposed on the outer packaging equipment, and a rotating positioning structure disposed on the two tables; The rotary positioning structure includes two symmetrically distributed rectangular frames, which are slidably mounted on a table. A cylinder is fixedly mounted on each of the two tables, and the telescopic end of the cylinder is fixedly connected to the rectangular frame on the same side. Rotating components and fixing components are provided inside the rectangular frames, and a driving component for driving the rotating components to rotate is provided on any one of the rectangular frames. The fixing component includes a semi-circular plate for supporting the corrugated cardboard box containing the rust inhibitor, and an L-shaped plate for positioning the corrugated cardboard box containing the rust inhibitor is mounted on the semi-circular plate.

[0006] Furthermore, two limiting grooves are provided on the semi-circular plate, and support columns are slidably installed on the two limiting grooves. The L-shaped plate is rotatably installed on the outer surface of the support columns, and locking screws for fixing their positions are threaded on both ends of the support columns.

[0007] Furthermore, the rectangular frame is provided with an arc-shaped cavity, and the rotating component includes an arc-shaped groove fixedly installed in the arc-shaped cavity. An arc-shaped bracket is slidably installed on the arc-shaped groove. An arc-shaped rack that cooperates with the driving component is fixedly installed on the arc-shaped bracket. An electric push rod A with its telescopic end fixedly connected to the semi-circular plate is fixedly installed on the arc-shaped bracket.

[0008] Furthermore, the driving component includes a straight rack slidably mounted on a rectangular frame, and the straight rack passes through the rectangular frame and meshes with an arc-shaped rack. An electric push rod B is fixedly mounted on the rectangular frame, and the telescopic end of the electric push rod B is fixedly connected to the straight rack.

[0009] Furthermore, an arc-shaped guide groove is provided on the arc-shaped groove body, and the arc of the arc-shaped guide groove is 110 degrees. An arc-shaped guide block with an arc of 20 degrees is fixedly installed at the bottom of the arc-shaped bracket, and the arc-shaped guide block is slidably connected to the arc-shaped guide groove.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This outer packaging equipment for rust inhibitor production adjusts the position of the support column in the limit groove by loosening the locking screw, changes the spacing of the L-shaped plates, and after the carton presses the L-shaped plates to flip, the cylinder pushes the rectangular frame to close, so that the L-shaped plates fit tightly against the carton. Thus, the self-weight of the rust inhibitor corrugated carton is used to achieve the functions of stable clamping and centering, avoiding the centrifugal force of rotation causing the rust inhibitor corrugated carton to deviate from the center position. 2. This outer packaging equipment for rust inhibitor production uses an L-shaped plate to clamp the carton. Electric push rod A lifts the carton, and electric push rod B pushes the straight rack and the arc rack to mesh, causing the arc bracket to rotate precisely 90 degrees along the arc groove. After rotation, the electric push rod A retracts and resets, and the rectangular frame temporarily supports the carton, achieving precise control of the rotation angle. This ensures that the longitudinal and transverse positions of the packing straps correspond, guaranteeing a uniform and firm binding effect. Furthermore, the cooperation between the arc guide block and the arc groove further ensures the accuracy of the rotation angle. 3. The outer packaging equipment used for rust inhibitor production adopts a split-type symmetrically distributed rotary positioning structure to ensure that during the process of binding longitudinal and transverse straps, the two rectangular frames are controlled to retract to the table surface, thereby exposing the binding channel between the two table surfaces and avoiding obstruction to the straps.

[0013] 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.

[0014] Example 1: Please refer to Figure 1-6 In this embodiment, an outer packaging device for the production of rust inhibitors includes two tables 1 set on the outer packaging device, and a rotating positioning structure 2 is provided on the two tables 1.

[0015] Example 2: Please refer to Figure 1-6 Based on Embodiment 1, the rotary positioning structure 2 includes two symmetrically distributed rectangular frames 21, and the rectangular frames 21 are slidably mounted on the platform 1. Cylinders 22 are fixedly mounted on both platforms 1, and the telescopic ends of the cylinders 22 are fixedly connected to the rectangular frames 21 on the same side. Rotating components 23 and fixed components 25 are provided inside the rectangular frames 21. A driving component 24 for driving the rotating component 23 to rotate is provided on any one of the rectangular frames 21. The fixing component 25 includes a semi-circular plate 251 for supporting the corrugated cardboard box containing the rust inhibitor, and an L-shaped plate 252 for positioning the corrugated cardboard box containing the rust inhibitor is mounted on the semi-circular plate 251.

[0016] The semi-circular plate 251 has two limiting grooves 253, and support columns 254 are slidably installed on the two limiting grooves 253. The L-shaped plate 252 is rotatably installed on the outer surface of the support column 254. Both ends of the support column 254 are threaded with locking screws 255 for fixing its position. Tightening or loosening the locking screws 255 adjusts the position of the support column 254 in the limiting groove 253, changes the spacing of the L-shaped plate 252, and the carton presses the L-shaped plate 252 to flip. In conjunction with the cylinder 22, the rectangular frame 21 is pushed to close, realizing the stable clamping of cartons of different sizes. This allows it to be adapted to various specifications of cartons. The carton does not loosen or shift during rotation, ensuring the binding accuracy.

[0017] It should be noted that the cylinder 22 drives the rectangular frame 21 to close, and the semi-circular plate 251 and L-shaped plate 252 support and center the carton. The drive component 24 drives the rotating component 23 to achieve a precise 90-degree rotation, thereby ensuring the accuracy of the carton rotation. In addition, the L-shaped plate 252 is used to clamp and fix the carton to avoid the centrifugal force during the rotation process causing the carton to shift, ensuring that the carton is kept in a centered position when bundled.

[0018] Using the above technical solution, loosen the locking screw 255, adjust the position of the support column 254 in the limiting groove 253, and set the distance between the two L-shaped plates 252 so that after the two semicircular plates 251 are closed, the distance between the two L-shaped plates 252 is adapted to the corrugated cardboard box for rust prevention. Finally, tighten the locking screw 255, place the cardboard box on the two tabletops 1 and press down on the shorter side of the two L-shaped plates 252. The cardboard box presses down on the L-shaped plates 252 so that their longer side flips towards the cardboard box. At this time, the longer side of the L-shaped plates 252 is parallel to the cardboard box. Start the cylinder 22 to extend and push the two rectangular frames 21 on both sides to move towards each other, so that the two semicircular plates 251 are closed, and the L-shaped plates 252 on the semicircular plates 251 move accordingly. At this time, the longer side of the two L-shaped plates 252 is tightly attached to the cardboard box, completing the centering positioning.

[0019] Example 3: Please refer to Figure 1-6 Based on Embodiment 2, the rectangular frame 21 is provided with an arc-shaped cavity 211. The rotating component 23 includes an arc-shaped groove 231 fixedly installed in the arc-shaped cavity 211. An arc-shaped bracket 232 is slidably installed on the arc-shaped groove 231. An arc-shaped rack 233 that cooperates with the driving component 24 is fixedly installed on the arc-shaped bracket 232. An electric push rod A234 whose telescopic end is fixedly connected to the semi-circular plate 251 is fixedly installed on the arc-shaped bracket 232. The arc-shaped bracket 232 slides in the arc-shaped groove 231. The arc-shaped rack 233 transmits power. The electric push rod A234 is connected to the semi-circular plate 251 to achieve stable rotation support and power transmission. The carton rotates smoothly with high positioning accuracy, avoiding shaking and deviation during rotation and ensuring the accuracy of the bundling position.

[0020] The driving component 24 includes a straight rack 241 slidably mounted on a rectangular frame 21, and the straight rack 241 passes through the rectangular frame 21 and meshes with an arc rack 233. An electric push rod B242 is fixedly mounted on the rectangular frame 21, and the telescopic end of the electric push rod B242 is fixedly connected to the straight rack 241. The electric push rod B242 pushes the straight rack 241, which meshes with the arc rack 233 to drive the arc bracket 232 to rotate precisely 90 degrees, thereby ensuring accurate rotation angle, ensuring the accuracy of the longitudinal and transverse positions of the packing strap, and ensuring a uniform and firm binding effect.

[0021] In addition, an arc-shaped guide groove is provided on the arc-shaped groove 231, and the arc of the arc-shaped guide groove is 110 degrees. An arc-shaped guide block 235 with an arc of 20 degrees is fixedly installed at the bottom of the arc-shaped support 232, and the arc-shaped guide block 235 is slidably connected to the arc-shaped guide groove. The arc-shaped guide block 235 slides in the arc-shaped guide groove, limiting the sliding range and ensuring accurate rotation trajectory. This makes the arc-shaped support 232 move stably and rotate accurately, further ensuring the positional accuracy of the carton after rotation, and making the packing strap centered and vertical.

[0022] Using the above technical solution, after the horizontal strapping is completed, the cylinder 22 is extended to close the two semicircular plates 251. The two L-shaped plates 252 are used to clamp and fix the corrugated cardboard box containing the rust inhibitor. The electric push rod B242 is then extended, driving the semicircular plates 251 to lift the corrugated cardboard box containing the rust inhibitor. At this time, the semicircular plates 251 are in a high position. The electric push rod B242 is then extended to push the straight rack 241, causing the straight rack 241 to drive the arc rack 233 to slide along the arc groove 231, thereby controlling the arc support 232. The semicircular plate 251 rotates 90 degrees synchronously, thereby causing the corrugated cardboard box containing the rust inhibitor to rotate 90 degrees. The electric push rod A234 is activated to retract, controlling the semicircular plate 251 to retract into the arc cavity 211. At this time, the semicircular plate 251 is in a low position, and the rectangular frame 21 temporarily supports the corrugated cardboard box containing the rust inhibitor. Then, the electric push rod B242 is activated to retract, controlling the two semicircular plates 251 to rotate and reset. Subsequently, the electric push rod A234 is activated again to extend, controlling the semicircular plate 251 to rise to the initial position and support the corrugated cardboard box containing the rust inhibitor.

[0023] The working principle of the above embodiments is as follows: When using the outer packaging equipment for rust inhibitor production, according to the specifications of the corrugated cardboard box for rust inhibitor, loosen the locking screw 255, adjust the position of the support column 254 in the limit groove 253, set the distance between the two L-shaped plates 252 so that after the two semi-circular plates 251 are closed, the distance between the two L-shaped plates 252 is adapted to the corrugated cardboard box for rust inhibitor, and finally tighten the locking screw 255. Place the carton on the two tabletops 1 and press down the shorter sides of the two L-shaped plates 252. The carton presses down on the L-shaped plates 252 so that their longer sides flip towards the carton. At this time, the longer side of the L-shaped plates 252 is parallel to the carton. The cylinder 22 extends, pushing the two rectangular frames 21 to move towards each other, causing the two semicircular plates 251 to close together. The L-shaped plates 252 on the semicircular plates 251 move accordingly. At this time, the longer sides of the two L-shaped plates 252 are tightly attached to the carton, completing the centering positioning. Then the cylinder 22 retracts and drives the two rectangular frames 21 to reset. Then the outer packaging equipment is started to tie the horizontal packing straps. After the horizontal strapping is completed, the cylinder 22 is extended and the two semicircular plates 251 are closed. The two L-shaped plates 252 are used to clamp and fix the corrugated cardboard box for rust inhibitor. The electric push rod B242 is extended and drives the semicircular plates 251 to lift the corrugated cardboard box for rust inhibitor. At this time, the semicircular plates 251 are in a high position. When the electric push rod B242 is activated, it extends and pushes the straight rack 241, causing the straight rack 241 to drive the arc rack 233 to slide along the arc groove 231, thereby controlling the arc bracket 232 and the semi-circular plate 251 to rotate 90 degrees synchronously, thereby driving the rust inhibitor corrugated cardboard box to rotate 90 degrees. Start the electric push rod A234 to retract, controlling the semicircular plate 251 to retract into the arc cavity 211. At this time, the semicircular plate 251 is in a low position, and the rectangular frame 21 temporarily supports the corrugated cardboard box for rust prevention. Then start the electric push rod B242 to retract, controlling the two semicircular plates 251 to rotate and reset. Then start the electric push rod A234 again to extend, controlling the semicircular plate 251 to rise to the initial position and support the corrugated cardboard box for rust prevention. At this time, the semicircular plate 251 is in the initial position. Then, the cylinder 22 is activated to retract and drive the two rectangular frames 21 to reset. Then, the outer packaging equipment is activated to perform longitudinal strapping, thereby completing the packaging and strapping operation of a single rust inhibitor corrugated cardboard box.
