Detailed Implementation
[0022] 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.
[0023] Please see Figures 1-4 This utility model provides a technical solution: a weighing device for enterprise production, including a weighing body 1, on which a weighing mechanism for enterprise production is provided, the weighing mechanism including:
[0024] The centering component includes a weighing platform 2 fixed on the upper surface of the weighing body 1. The weighing platform 2 has a sliding groove 202 inside, and a limiting plate 204 connected by an opening and closing component is provided inside the sliding groove 202.
[0025] The support assembly includes a support shaft 4 on both sides of the weighing platform 2, and an auxiliary platform 401 is rotatably connected to the outer wall of the support shaft 4.
[0026] In a preferred embodiment, the opening and closing assembly includes a bidirectional screw 203 rotatably connected inside the slide groove 202, a limiting plate 204 with its lower end slidably connected to the inner wall of the slide groove 202, two sets of limiting plates 204 being threadedly connected to the bidirectional screw 203, the limiting plates 204 being configured as two sets, the two sets of limiting plates 204 being located on both sides of the weighing platform 2, a first rubber pad 201 being evenly distributed on the upper surface of the weighing platform 2, and a second rubber pad 205 being fixed to the inner wall of the limiting plate 204.
[0027] The rotation of the bidirectional screw 203 drives the two sets of limiting plates 204 to slide relative to each other along the slide groove 202 until they come into contact with the material, thereby achieving automatic centering of the material. This ensures that the goods are placed in the center of the weighing platform 2, avoiding the influence of eccentric loads on the weighing results and weighing errors caused by the offset of the goods, thus improving the accuracy of weighing. Furthermore, the second rubber pad 205 on the inner wall of the limiting plate 204 and the first rubber pad 201 on the upper surface of the weighing platform 2 can buffer the force on the goods during clamping and weighing, preventing the surface of the goods from being scratched or damaged, and protecting the integrity of the goods.
[0028] The material to be weighed is placed on the weighing platform 2, and the first rubber pad 201 can increase friction and prevent the material from sliding.
[0029] In a preferred embodiment, a support shell 3 is fixed to the lower end face of the weighing platform 2, and an insert rod 301 is slidably connected inside the support shell 3. A positioning shell 302 is fixed to the lower end face of the auxiliary platform 401. One end of the insert rod 301 is slidably connected to the positioning shell 302, and the other end of the insert rod 301 is provided with a push assembly for driving. The push assembly includes an electric push rod 5 fixed to the edge of the lower end face of the weighing platform 2. A push block 501 is fixed to the telescopic end of the electric push rod 5. Movable rods 502 are rotatably connected to both sides of the push block 501 via a rotating shaft. A connecting plate 503 is fixed to one end of the insert rod 301. A connecting block 504 is fixed to the side wall of the connecting plate 503. A rotating shaft is provided on the side wall of the connecting block 504 and is rotatably connected to the other end of the movable rod 502.
[0030] When it is necessary to expand the weighing area, the auxiliary platform 401 is unfolded on both sides of the load-bearing platform 2 via the support shaft 4. The electric push rod 5 is activated, and the telescopic end of the electric push rod 5 extends, driving the push block 501 to move forward. One end of the movable rod 502 on both sides of the push block 501 moves with the push block 501. Since the other end of the movable rod 502 is rotatably connected to the connecting block 504 through the rotating shaft, and the connecting block 504 is fixed to the side wall of the connecting plate 503, and the connecting plate 503 is fixed to one end of the insertion rod 301, the movable rod 502 will push the connecting plate 503 to move outward, thereby driving the insertion rod 301 to slide inside the support housing 3, so that one end of the insertion rod 301 slides out of the positioning housing 302 and inserts the insertion rod 301 into the interior of the positioning housing 302, so that the auxiliary platform 401 is fixed on both sides of the weighing platform 2.
[0031] The auxiliary platform 401 is connected to the weighing platform 2 via the support shaft 4, and can be unfolded and retracted through the cooperation of the insertion rod 301 and the positioning shell 302. When encountering larger-sized goods, unfolding the auxiliary platform 401 can expand the weighing area to meet the weighing needs of goods of different sizes, improve the flexibility of the weighing device, and improve the stability of the weighed object support.
[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0033] During operation, in the weighing process of enterprise production, the material to be weighed is first placed on the weighing platform 2. At this time, the first rubber pad 201 evenly distributed on the upper surface of the weighing platform 2 can increase the friction between the material and the platform and prevent the material from sliding. Then, the drive device connected to the bidirectional screw 203 is started, so that the bidirectional screw 203 rotates in the slide groove 202 opened inside the weighing platform 2. Since the lower ends of the two sets of limiting plates 204 are slidably connected to the inner wall of the slide groove 202 and are respectively threaded to the bidirectional screw 203, the rotation of the bidirectional screw 203 will drive the two sets of limiting plates 204 to slide relative to each other along the slide groove 202 until they contact the material, realizing the automatic centering of the material and ensuring that the goods are placed in the center position of the weighing platform 2. This avoids the influence of eccentric load on the weighing results and the weighing error caused by the offset of the goods, thus improving the weighing accuracy. At the same time, the second rubber pad 205 and the first rubber pad 201 on the inner wall of the limiting plate 204 can buffer the force on the goods during the clamping and weighing process, prevent the surface of the goods from being scratched or damaged, and protect the integrity of the goods.
[0034] When encountering large-sized goods requiring an expanded weighing area, the auxiliary platform 401 is extended on both sides of the weighing platform 2 via the support shaft 4. Then, the electric push rod 5, fixed at the lower edge of the weighing platform 2, is activated. The telescopic end of the electric push rod 5 extends, driving the push block 501 fixed thereon to move forward. One end of the movable rod 502, rotatably connected to both sides of the push block 501 via a rotating shaft, moves with the push block 501. Since the other end of the movable rod 502 is rotatably connected to the connecting block 504 fixed to the side wall of the connecting plate 503 via a rotating shaft, and the connecting plate 503 is connected to one end of the insertion rod 301... Since the auxiliary platform 401 is fixed, the movable rod 502 will push the connecting plate 503 to move outward, thereby causing the insertion rod 301 to slide inside the support shell 3 fixed on the lower end face of the weighing platform 2. This allows one end of the insertion rod 301 to slide out of the positioning shell 302 fixed on the lower end face of the auxiliary platform 401. After the auxiliary platform 401 is unfolded to the appropriate position, the electric push rod 5 is controlled to re-insert the insertion rod 301 into the positioning shell 302, fixing the auxiliary platform 401 to both sides of the weighing platform 2. This meets the weighing requirements of goods of different sizes, improves the flexibility of the weighing device and the stability of the weighed object support.
