Description

Technical Field

[0001] The present application relates to the technical field of labor protection shoe production, and in particular to a cleaning device. Background Art

[0002] Labor insurance rubber shoes are protective shoes made of natural rubber or synthetic rubber as the main material. They have the characteristics of anti-slip, wear-resistant, waterproof, moisture-proof, acid-base corrosion-resistant, etc. The toe of labor insurance rubber shoes is usually equipped with a steel toe cap to resist heavy objects, impact and extrusion, so as to protect the feet, especially the toes, from injury in dangerous working environments and ensure the safety of workers.

[0003] After the steel toe cap is stamped, it needs to be cleaned and sprayed to enhance the adhesion of the sprayed plastic layer, improve corrosion resistance, and ensure the spraying effect. The steel toe cap is generally in an arc or semicircular shape that matches the toe cap, and its bottom is provided with a vertical folded edge facing inward. When the ultrasonic cleaning device is cleaning the steel toe cap, the steel toe cap accumulates inside the hanging basket, and two adjacent steel toe caps are easily embedded together, resulting in a large cleaning dead angle.

[0004] Referring to the Chinese patent application document with announcement number CN214289740U, entitled "An Ultrasonic Cleaner", a cleaning chamber is divided into three layers by a plurality of cleaning baskets, so as to achieve the purpose of storing items to be cleaned in layers and reduce the accumulation of items.

[0005] With regard to the above technical scheme, the layered steel toe caps may block each other, and ultrasonic waves are difficult to reach the blocked parts, thus forming cleaning dead corners and affecting the cleaning effect. A large number of tiny bubbles will be generated in the cleaning liquid under the action of ultrasonic waves. The bubbles will be blocked by the multi-layered steel toe caps during the rising process, and the escape will be difficult. The intensity and effect of the cavitation will be affected, thereby reducing the cleaning efficiency to a certain extent. Summary of the invention

[0006] In view of this, the present application provides a cleaning device, which is mainly used to solve the problem that multi-layered steel toe caps are likely to affect the cleaning effect and efficiency during ultrasonic cleaning.

[0008] By adopting the above technical solution, when cleaning steel toe caps, multiple racks inside the cleaning tank can be tilted and staggered, reducing mutual obstruction between the racks and the steel toe caps, reducing cleaning dead angles, and making ultrasonic coverage more uniform, thereby improving cleaning effect and cleaning efficiency.

[0009] Optionally, a mesh plate is provided at the bottom of the material cover, and a spring is provided between the mesh plate and the material cover.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 8 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 The present embodiment provides a cleaning device, including an ultrasonic cleaning machine body 1, a lifting assembly, a material rack 3, a clamping member 4 and a rotation dislocation assembly. The lifting assembly is used to install and drive the material rack 3 to move up and down. The lifting assembly includes a support frame 11, a connecting arm 12, a vertical driving member 13 and a frame 2. The frame 2 is arranged between the connecting arms 12. The connecting arms 12 are slidably connected in the slide groove on the support frame 11. The vertical driving member 13 drives the connecting arms 12 to move the frame 2 up and down. There are multiple material racks 3, and multiple material racks 3 are detachably arranged inside the frame 2. The clamping member 4 limits the material rack 3 to make the connection between the material rack 3 and the frame 2 more secure.

[0026] Among them, refer to Figure 2 and Figure 3The rotation dislocation assembly includes a movable groove 21, a mounting member 22, a rotary drive member 24 and a slider 25. Multiple movable grooves 21 are arranged on both sides of the frame 2. The multiple movable grooves 21 are arranged linearly in the vertical direction, and the length of the movable grooves 21 gradually shortens from top to bottom. The mounting member 22 is arranged on the inner side of the frame 2 for mounting the material rack 3. The slider 25 is fixedly connected to the middle of one side of the mounting member 22 close to the frame 2, and the slider 25 is slidably arranged inside the movable groove 21; the rotary drive member 24 includes a second motor 241, a toothed disc 242 and a gear ring 243. The gear ring 243 is fixedly connected to one side of the frame 2. The second motor 241 is arranged on the connecting arm 12, and the output shaft of the second motor 241 is fixedly connected to the toothed disc 242.

[0027] The second motor 241 drives the gear ring 243 to rotate through the gear disc 242, so that the frame 2 drives the material rack 3 to rotate in the cleaning tank in the ultrasonic cleaning machine body 1. Under the action of gravity, the slider 25 on the mounting member 22 moves along the corresponding movable groove 21. Due to the different lengths of the movable grooves 21, the moving distances of the mounting member 22 are also different, so that two adjacent material racks 3 are staggered with each other for a distance. When the frame 2 is in an inclined posture in the cleaning tank, the material racks 3 inside it are inclined and staggered, which can reduce the obstruction between the material racks 3 and the steel ferrules, which is beneficial to the cleaning work.

[0028] Among them, refer to Figure 4 , Figure 5 and Figure 7 The material rack 3 includes a material cover 31, a material tray 32, an insert 321, a material cavity 322 and a connecting groove 323. The material tray 32 is provided with a plurality of material cavities 322 for individually containing steel toe caps to prevent the steel toe caps from colliding with each other or being embedded together when the material rack 3 moves. The insert 321 is symmetrically arranged on both sides of the material tray 32. The mounting member 22 is provided with slots adapted to the insert 321 for mounting and fixing the material tray 32. The connecting grooves 323 are symmetrically arranged on the upper surface of the material tray 32. The bottom of the material cover 31 is provided with a connecting strip adapted to the connecting groove 323. The material cover 31 is clamped with the material tray 32 through the connecting groove 323 and the connecting strip.

[0029] The steel toe cap is independently placed in the material cavity 322 in the material tray 32, and the steel toe caps in the material cavity 322 are oriented in the same direction. When the frame 2 and the material rack 3 are removed from the cleaning tank, the opening of the steel toe cap is turned downward by rotating the offset component, which can avoid liquid accumulation inside the steel toe cap and facilitate its drying.

[0030] Among them, refer to Figure 3 and Figure 6 The clamping member 4 includes a stopper 41, a tension spring 42 and a socket 43. The socket 43 is provided at the top of one end of the mounting member 22, the stopper 41 is inserted into the socket 43, and the tension spring 42 is sleeved on the top outer side of the stopper 41.

[0031] The blocking rod 41 is pulled, and the blocking rod 41 moves upward to stretch the tension spring 42. When the bottom of the blocking rod 41 is moved out of the slot inside the mounting member 22, the limiting of the material tray 32 can be released.

[0032] In addition, refer to Figure 1 , Figure 2 and Figure 8 The vertical driving member 13 includes a lead screw 131 and a first motor 132. The lead screw 131 is rotatably connected to the support frame 11 and is threadedly connected to the connecting arm 12. The first motor 132 is disposed on the top of the support frame 11 to drive the lead screw 131 to rotate.

[0033] The output shaft of the first motor 132 drives the lead screw 131 to rotate. Under the action of the lead screw 131, the connecting arm 12 moves upward or downward along the support frame 11, so that the frame 2 and the material rack 3 are moved out of or into the cleaning tank.

[0034] Reference Figure 4 and Figure 5 The material cover 31 includes a mesh plate 311 and a spring 313. The mesh plate 311 is arranged at the bottom of the material cover 31, and the spring 313 is arranged between the mesh plate 311 and the material cover 31.

[0035] The mesh plate 311 is elastically arranged at the bottom of the material cover 31 through the spring 313. The mesh plate 311 is used to replace the material cover 31 to contact and press the steel toe inside the material cavity 322. At this time, the spring 313 is in a compressed state. Under the reaction force of the spring 313, the connection between the material cover 31 and the material tray 32 will be more secure.

[0036] Reference Figure 4 and Figure 5 A connecting rod 314 penetrating the material cover 31 is provided on the mesh plate 311, a pull plate 312 is provided on the top of the connecting rod 314, and a plurality of limiting plates 23 corresponding to the mounting member 22 are provided on the inner side of the frame body 2, and the limiting plate 23 is inclined downward on the side close to the clamping member 4.

[0037] When the material rack 3 is installed on the frame 2, the bottom of the pull plate 312 will conflict with the bottom of the limit plate 23. As the material rack 3 moves, the pull plate 312 moves up under the action of the limit plate 23 and further compresses the spring 313. At the same time, the mesh plate 311 also moves up under the action of the connecting rod 314. At this time, the distance between the mesh plate 311 and the material tray 32 increases. Under the premise of ensuring that the steel toe cap inside the material cavity 322 does not twist, the steel toe cap can move slightly in the material cavity 322, which can further reduce the cleaning dead angle of the steel toe cap.

[0038] Reference Figure 3 and Figure 5A baffle 315 for shielding the material tray 32 is provided on one side of the material cover 31 close to the clamping member 4 .

[0039] When cleaning is completed, the rotating drive member 24 drives the frame 2 to flip the rack 3 to 90 degrees. At this time, the baffle 315 is located on the top of the rack 3. When the rack 3 is removed from the cleaning tank, impurities floating on the surface of the cleaning tank can be prevented from adhering to the ladle head again.

[0040] Among them, refer to Figure 6 The bottom of the side of the blocking rod 41 away from the limiting plate 23 is an inclined surface.

[0041] When the inserting strip 321 is installed into the slot on the mounting member 22 , as the inserting strip 321 moves, the inserting strip 321 abuts against the inclined surface of the blocking rod 41 , so the blocking rod 41 can be moved upward without pulling the blocking rod 41 , which makes the operation more convenient and labor-saving.

[0042] The implementation principle of a cleaning device in the embodiment of the present application is: Place the steel toe caps in the material cavity 322 in the material tray 32 respectively, so that the openings of the steel toe caps are in the same direction, and then clamp the material cover 31 on the top of the material tray 32. Under the action of the spring 313, the steel toe caps are pressed tightly in the material cavity 322 to avoid damage to the steel toe caps when the material rack 3 is transferred; clamp the material rack 3 into the mounting parts 22 respectively, and use the clamping parts 4 to limit them. When the material rack 3 is installed on the frame 2, the spring 313 is further compressed, and the pull plate 312 drives the connecting rod 314 to move the mesh plate 311 upward. Under the premise of ensuring that the steel toe cap does not twist, the activity space of the steel toe cap is increased, and the contact surface between the steel toe cap and the material rack 3 is prevented from having a cleaning dead angle, so that the steel toe caps can be cleaned more thoroughly; During cleaning, under the action of the vertical drive member 13, the material rack 3 is connected to the frame 2 and enters the cleaning tank in the ultrasonic cleaning machine body 1. The rotating drive member 24 drives the frame 2 to rotate. Under the action of gravity, the slider 25 on the mounting member 22 moves along the corresponding movable groove 21. Due to the different lengths of the movable grooves 21, the distances moved by the mounting member 22 are also different, so that two adjacent material racks 3 are staggered from each other. When the frame 2 is in an inclined posture in the cleaning tank, the material racks 3 inside it are inclined and staggered, thereby reducing the obstruction between the material racks 3 and the steel ferrules. In addition, the rotating drive member 24 can change the rotation direction regularly so that the steel ferrules on the material rack 3 are fully in contact with the cleaning liquid, thereby improving the cleaning effect; After cleaning is completed, the rotating drive member 24 drives the frame 2 to rotate, so that the material rack 3 on the frame 2 rotates 90 degrees. At this time, the baffle 315 is located directly above the material rack 3, and the opening of the steel toe cap faces downward. The vertical drive member 13 drives the connecting arm 12 to move upward, and the connecting arm 12 drives the frame 2 to move the material rack 3 out of the cleaning tank. The rotated material rack 3 can reduce the contact area with the water surface, and cooperate with the baffle 315 to prevent impurities floating on the surface of the cleaning liquid from adhering to the steel toe cap again, thereby ensuring the cleaning effect. Since the opening of the steel toe cap faces downward, no water will remain inside the steel toe cap when it moves upward, which is conducive to the next step of drying.

[0043] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0044] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
