[0017] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] For example, see Figure 1-Figure 10 The present invention provides a technical solution for a weighing machine with an easy-to-clean table top: the weighing machine with an easy-to-clean table top comprises: a weighing machine body 1, a weighing platform 11 is arranged above the weighing machine body 1, a lifting mechanism is arranged on the outer wall of the bottom of the weighing machine body 1, a mounting shell 2 is arranged above the lifting structure, a pushing mechanism is arranged inside the mounting shell 2, a circular groove is opened on the outer wall of the top of the mounting shell 2, and the lifting mechanism comprises a first motor 3, the outer wall of the bottom of the weighing machine body 1 is fixedly connected to the outer wall of the top of the first motor 3, a threaded rod 31 is fixedly connected to the output end of the first motor 3, the outer wall of the threaded rod 31 is threadedly connected to a support frame 32, and the outer wall of the support frame 32 is slidably connected to the inside of the weighing machine body 1.

[0019] When the bottom of the mounting shell 2 is higher than the position of the weighing platform 11, the movement of the first motor 3 can be stopped, thereby preventing the mounting shell 2 from remaining on the weighing platform 11 when it is not needed to work. Accordingly, by setting up the lifting mechanism, the mounting shell 2 can be received under the weighing platform 11 when not in use, so that the surface of the weighing platform 11 remains tidy without affecting the weighing of the material, thereby reducing the collision of the material with the mounting shell 2 during weighing and transmission.

[0020] Embodiment 2, on the basis of embodiment 1, a rotating rod 22 is rotatably connected to the middle position of the outer wall at the top of the support frame 32, the outer wall at the top of the rotating rod 22 is fixedly connected to the outer wall at the bottom of the mounting shell 2, a limiting hole 24 is provided on the outer wall at the top of the support frame 32, the two limiting holes 24 are internally slidably connected to the limiting blocks 23, the outer walls at the bottom of the two limiting blocks 23 are fixedly connected to the mounting plate 21, the outer wall at the top of the mounting plate 21 is fixedly connected to the reset spring 25, and the outer walls at the top of the two reset springs 25 are fixedly connected to the inner wall at the top of the support frame 32.

[0021] By fixing the limit blocks 23 on both sides of the mounting shell 2, the mounting shell 2 can be limited, which prevents the mounting shell 2 from being offset due to the friction between the rotation of the weighing platform 11 and the cleaning structure when the mounting shell 2 is working. This correspondingly increases the stability of the mounting shell 2 during operation and prevents the edge of the cleaning structure from failing to contact the edge of the weighing platform 11 when the mounting shell 2 is tilted, causing some positions of the weighing platform 11 to not be cleaned, thereby further increasing the cleaning effect of the cleaning structure.

[0022] Embodiment 3, on the basis of embodiment 2, the pushing mechanism includes a second motor 44, the outer wall of the bottom of the second motor 44 is fixedly connected to the bottom of the inner wall of the circular groove, a track groove 4 is provided on the outer wall of the top of the mounting shell 2 close to the circular groove, the output end of the second motor 44 is fixedly connected to a rotating plate 45, the outer wall of the top of the rotating plate 45 is fixedly connected to a mounting rod 46 at a position deviating from the axis, the outer wall of the mounting rod 46 is rotatably connected to a driving plate 42, a strip groove is provided on the driving plate 42, the inside of the strip groove is slidably connected to a force-bearing rod 43, the outer wall of the bottom of the force-bearing rod 43 is fixedly connected to an L-shaped push rod 41, the outer wall of the L-shaped push rod 41 is slidably connected to the inside of the track groove 4, and the outer wall of the bottom of the L-shaped push rod 41 is fixedly connected to a sliding shell 2 51.

[0023] Through the movement of the L-shaped push rod 41, the sliding shell 2 51 can be pushed to move left and right inside the cavity, so that the cleaning structure at the bottom of the sliding shell 2 51 can brush back and forth on the weighing platform 11, and the dirt on the surface of the weighing platform 11 can be cleaned, thereby avoiding the cleaning structure being statically installed on the mounting shell 2, and only relying on the movement of the weighing platform 11 at the bottom of the cleaning structure to clean the dirt. Correspondingly, the cleaning structure can reciprocate inside the mounting shell 2, thereby increasing the cleaning effect of the cleaning structure on the weighing platform 11.

[0024] Embodiment 4, on the basis of embodiment 3, a cavity is formed on the outer wall at the bottom of the mounting shell 2, a partition 54 is fixedly connected to the middle position of the cavity, a square groove is formed on the partition 54, a fixing rod 56 is rotatably connected inside the square groove, the outer walls of the four fixing rods 56 are fixedly connected to gears 53, the outer wall at the top of the sliding shell 2 51 is fixedly connected to the tooth seat 1 52, the outer wall on one side of the tooth seat 1 52 is meshingly connected to the outer wall of the gear 53, the inner side of the cavity close to the partition 54 is slidably connected to the sliding shell 1 5, the outer wall at the top of the sliding shell 1 5 is fixedly connected to the tooth seat 2 55, the outer wall on one side of the tooth seat 2 55 is meshingly connected to the outer wall of the gear 53.

[0025] Through the cooperation of the tooth seat 1 52, the gear 53 and the tooth seat 2 55, the cleaning structures at the bottom of the sliding shell 1 5 and the sliding shell 2 51 can be moved at the same time. By brushing in opposite directions, the two cleaning structures can cover the surface of the weighing platform 11 more comprehensively, ensuring that every position can be cleaned, avoiding the slow cleaning effect of the unidirectional or static cleaning structure on the surface of the weighing platform 11, and correspondingly improving the cleaning efficiency of the weighing platform 11. By brushing in opposite directions, a stronger friction force can be generated, which is helpful to remove stubborn stains attached to the surface of the weighing platform 11.

[0026] Embodiment 5. On the basis of embodiment 4, a cleaning structure is provided on the outer wall of the bottom of the sliding shell 5, the cleaning structure includes a cleaning brush 61, the outer wall of the top of the cleaning brush 61 is fixedly connected to the outer wall of the bottom of the sliding shell 5, the cleaning brush 61 is fixedly connected, the outer wall of the bottom of the sliding shell 5 is provided with a discharge port, the inner part of the discharge port is rotatably connected with a rotating column 6, the outer wall of the bottom of the cleaning brush 61 is in active contact with the outer wall of the top of the weighing platform 11, the outer wall of the rotating column 6 is in rotatable contact with the outer wall of the top of the weighing platform 11, the outer wall of the bottom of the mounting shell 2 is provided with a T-slot, the inner part of the T-slot is slidably connected with a T-plate 62, the outer wall of the bottom of the T-plate 62 is fixedly connected with a cleaning cotton 63, the outer wall of the bottom of the cleaning cotton 63 is in active contact with the outer wall of the top of the weighing platform 11.

[0027] By brushing the cleaning brush 61 back and forth on the weighing platform 11, the detergent adhering to the surface of the weighing platform 11 is brushed away and integrated, thereby increasing the cleaning efficiency of the cleaning brush 61 on the weighing platform 11, making it easier to clean stubborn stains and correspondingly shortening the working time of the cleaning brush 61.

[0028] In actual use, first, start the first motor 3, and then the first motor 3 can drive the threaded rod 31 to rotate, and then the rotation of the threaded rod 31 can make the support frame 32 move upward inside the weighing machine body 1, and then the upward movement of the support frame 32 can push the mounting shell 2 to move upward. When the bottom of the mounting shell 2 is higher than the position of the weighing platform 11, the movement of the first motor 3 can be stopped, so as to avoid the mounting shell 2 being still on the weighing platform 11 when it is not needed to work. Correspondingly, through the setting of the lifting mechanism, the mounting shell 2 can be received under the weighing platform 11 when it is not in use, so that the surface of the weighing platform 11 remains clean without affecting the weighing of the material, thereby reducing the collision of the material with the mounting shell 2 during weighing and transmission.

[0029] By making the bottom of the mounting shell 2 higher than the top of the weighing platform 11, the mounting shell 2 can be rotated by the operator by hand, and then by rotating the mounting shell 2, the mounting shell 2 can drive the rotating rod 22 to rotate on the support frame 32. After the mounting shell 2 is rotated ninety degrees, the mounting shell 2 and the weighing platform 11 can be made perpendicular, thereby moving the cleaning structure to the surface of the weighing platform 11, avoiding the need for complicated steps to adjust the mounting shell 2, and correspondingly improving the efficiency of adjusting the mounting shell 2. By placing the mounting shell 2 horizontally on the weighing platform 11, it can be the same width as the weighing platform 11, which is convenient for the cleaning structure to clean it.

[0030] When the mounting shell 2 is placed horizontally on the weighing platform 11, the bottom of the mounting shell 2 can release the limit block 23. At this time, under the action of the reset spring 25, the mounting plate 21 can be driven to move upward, and then through the upward movement of the mounting plate 21, the limit block 23 can be moved out of the interior of the limit hole 24, so that the limit block 23 is fixed on both sides of the mounting shell 2, and the mounting shell 2 can be limited, avoiding the displacement of the mounting shell 2 due to the friction between the rotation of the table top of the weighing platform 11 and the cleaning structure when the mounting shell 2 is working, which correspondingly increases the stability of the mounting shell 2 during operation, and prevents the edge of the cleaning structure from not contacting the edge of the weighing platform 11 when the mounting shell 2 is tilted, resulting in some positions of the weighing platform 11 not being cleaned, further increasing the cleaning effect of the cleaning structure.

[0031] It should be noted that when the installation shell 2 is finished working, the operator can manually push the limit block 23 upwards so that the top of the limit block 23 is flush with the top of the limit hole 24, and the limit of the installation shell 2 by the limit block 23 can be released, and the installation shell 2 can be rotated to return to its original position.

[0032] It should be noted that: since the weighing platform 11 has the function of transmitting materials when working, the conveying function can be started when the weighing platform 11 is cleaned, so that the table top of the weighing platform 11 can be rotated. At this time, only the cleaning structure needs to be placed horizontally on the weighing platform 11 to clean the surface of the weighing platform 11.

[0033] By starting the movement of the second motor 44, and then through the movement of the second motor 44, the rotating plate 45 can drive the mounting rod 46 to rotate, and then the rotation of the mounting rod 46 can drive the driving plate 42 to rotate accordingly, and then through the movement of the driving plate 42, the strip groove on the driving plate 42 can push the force-bearing rod 43, so that the force-bearing rod 43 drives the L-shaped push rod 41 to move left and right inside the track groove 4, and then through the movement of the L-shaped push rod 41, the sliding shell 51 can be pushed to move left and right inside the cavity, so that the cleaning structure at the bottom of the sliding shell 51 can be brushed back and forth on the weighing platform 11, so that the dirt on the surface of the weighing platform 11 can be cleaned, avoiding the cleaning structure being statically installed on the mounting shell 2, and only relying on the movement of the weighing platform 11 at the bottom of the cleaning structure to clean the dirt, and correspondingly, the cleaning structure is reciprocated inside the mounting shell 2, which can increase the cleaning effect of the cleaning structure on the weighing platform 11.

[0034] Through the movement of the sliding shell 2 51, the tooth seat 1 52 fixedly connected to the sliding shell 2 51 can be moved accordingly, and then through the movement of the tooth seat 1 52, the gear 53 can drive the fixed rod 56 to rotate accordingly, and then through the meshing connection between the gear 53 and the tooth seat 2 55, when the gear 53 rotates accordingly, the tooth seat 2 55 can drive the sliding shell 1 5 to move accordingly, and then through the rotation of the sliding shell 1 5, the sliding shell 1 5 can drive the cleaning structure at the bottom to move accordingly, and through the tooth seat 1 52, the gear The cooperation between 53 and the gear seat 2 55 can make the cleaning structures at the bottom of the sliding shell 1 5 and the sliding shell 2 51 move at the same time. By brushing in opposite directions, the two cleaning structures can cover the surface of the weighing platform 11 more comprehensively, ensuring that every position can be cleaned, avoiding the slow cleaning effect of the unidirectional or static cleaning structure on the surface of the symmetrical weighing platform 11, and correspondingly improving the cleaning efficiency of the symmetrical weighing platform 11. By brushing in opposite directions, a stronger friction force can be generated, which is helpful to remove stubborn stains attached to the surface of the weighing platform 11.

[0035] When the sliding shell 5 drives the cleaning brush 61 to brush the surface of the weighing platform 11, the rotating column 6 rolls on the surface of the weighing platform 11. Then, through the rotation of the rotating column 6, the detergent inside the sliding shell 5 can be transmitted to the weighing platform 11 through the outer wall of the rotating column 6. Then, the cleaning brush 61 brushes back and forth on the weighing platform 11 to brush away and integrate the detergent adhering to the surface of the weighing platform 11, thereby increasing the cleaning efficiency of the cleaning brush 61 on the weighing platform 11, making it easier to clean stubborn stains and shortening the working time of the cleaning brush 61 accordingly.

[0036] When the surface cleaned by the cleaning brush 61 is transferred to the bottom of the cleaning cotton 63, the surface can be wiped by the cleaning cotton 63 to wipe off the residual detergent on the surface of the weighing platform 11, thereby completing the cleaning of the weighing platform 11. When the bottom of the cleaning cotton 63 is dirty and the surface of the weighing platform 11 is not wiped clean, the T-shaped plate 62 can be pulled from the inside of the T-shaped slot to replace the cleaning cotton 63, thereby maintaining the working state of the cleaning cotton 63.

[0037] It should be noted that: by taking out the piston block which is movably connected to the sliding shell 2 51 , the sliding shell 1 5 and the top of the mounting shell 2 , the cleaning agent can be added to the inside of the sliding shell 1 5 and the sliding shell 2 51 .

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
