[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0024] Example:
[0025] like Figs. 1 to 5 As shown, a lifting and correcting structure for a fast grain weighing scale includes an integrated bracket 2 and a lifting support 3. The integrated bracket 2 serves as the basic support for the entire structure, providing a stable installation platform for the lifting support 3. The lifting support 3 is mounted on the integrated bracket 2 and can be lifted up and down to adjust the height of the weighing scale 1 to adapt to different weighing needs. A hand-cranked jack 4 is located on the front side of the lifting support 3 and is the main power source for driving the lifting support 3 to move up and down. Through hand-cranking operation, the height of the lifting support 3 can be precisely controlled to achieve the lifting and lowering adjustment of the weighing scale 1. Connecting plates 9 are evenly distributed on the rear side of the lifting support 3 and are used to connect the support frame 6 and the fixed frame 7. A slot 11 is opened on the upper end face of the connecting plate 9 and is used to connect the crossbar 10 to drive the weighing scale 1 to lift and lower. The fixed frame 7 is installed on the upper side of the support frame 6, and the weighing scale 1 is installed on it. The fixed frame 7 is used to fix the weighing scale 1 and ensure the stability of the weighing scale 1 during the weighing process. Support frame 6: Located on the rear side of the lifting support 3, it provides support for the fixed frame 7. The end baffles 5 are U-shaped and symmetrically arranged on the left and right sides of the front end of the fixed frame 7. A crossbar 10 connects the two sets of end baffles 5, enhancing the overall integrity and stability of the structure. The correction component 8 is located at the connection between the connecting plate 9 and the crossbar 10, guiding the weighing scale 1 to remain centered during lifting and lowering, thus correcting its position and effectively preventing displacement during lifting and lowering. This design solves the problem in existing technologies where the weighing scale 1 is prone to positional displacement during lifting and lowering, affecting weighing accuracy.
[0026] In the embodiment, the correction assembly 8 comprises a positioning baffle 81, a first correction sheet 82 and a second correction sheet 83, the first correction sheet 82 and the second correction sheet 83 are each provided with two groups, the positioning baffle 81 is provided at the upper front end of the end baffle 5 and is in an integrated structure, the integrated design enhances the stability of the positioning baffle 81, so that it is not easy to loosen or deform when bearing external force, and provides a reliable foundation position for the whole correction assembly 8, the first correction sheet 82 is welded and fixed on the outer side of the connecting hanging plate 9, the second correction sheet 83 is welded and fixed on the inner side of the positioning baffle 81, and the first correction sheet 82 and the second correction sheet 83 cooperate with each other to play a role of positioning and correction in the lifting process. When the lifting support 3 drives the fixed frame 7 and the weighing scale 1 to lift, the first correction sheet 82 and the second correction sheet 83 are in close contact, and the second correction sheet 83 can restrict the first correction sheet 82, so as to limit the horizontal deviation of the fixed frame 7, ensure that the weighing scale 1 always remains in the central position, and thus ensure the stability and weighing accuracy of the weighing scale 1 in the lifting process.
[0027] In the embodiment, the first correction sheet 82 and the second correction sheet 83 are in a corresponding position, which ensures the balance of the correction effect, so that the correction force can be uniformly distributed on the fixed frame 7, improves the accuracy and reliability of the correction, and prevents the first correction sheet 82 and the second correction sheet 83 from being deviated and abraded. The first correction sheet 82 and the second correction sheet 83 are of the same specification, so the same mold and process can be used in the manufacturing process, which reduces the manufacturing cost and improves the production efficiency. At the same time, the same specification makes the installation process more simple, reduces the installation errors or debugging difficulties caused by specification differences, and the first correction sheet 82 and the second correction sheet 83 are both provided in an L-shaped structure and the two ends are fixed points. The design makes the correction sheet cooperate with the connecting hanging plate 9 and the positioning baffle 81 to form a triangular structure, improves the structural strength of the correction sheet, better disperses stress, reduces the possibility of deformation and damage, and improves the service life and reliability of the correction assembly 8.
[0028] In the embodiment, the first correction sheet 82 is welded on the outer side of the connecting hanging plate 9 with the short side downward and the long side upward, and is located at the front side of the clamping groove 11, the second correction sheet 83 is welded on the inner side of the positioning baffle 81 with the short side upward and the long side downward, and the long side surfaces of the first correction sheet 82 and the second correction sheet 83 are in close contact. The installation structure of the first correction sheet 82 and the second correction sheet 83 forms a complementary posture, when the lifting support 3 drives the fixed frame 7 and the weighing scale 1 to lift, the long side surfaces of the first correction sheet 82 and the second correction sheet 83 are in close contact and resist connection, and interact with each other, the first correction sheet 82 provides a limiting force inward and outward for the second correction sheet 83, prevents the deviation of the fixed frame 7, so that the two groups of first correction sheets 82 are always located between the two groups of second correction sheets 83, realizes the correction of the fixed frame 7, and further ensures that the weighing scale 1 is in the central position.
[0029] In the embodiment, the length of the long side of the first and second correction pieces 82 and 83 is 40-60 mm, the length of the short side is 20-30 mm, and the thickness is 3-5 mm. The first and second correction pieces 82 and 83 are made of Q235B carbon steel plate, which has moderate yield strength and tensile strength, and can meet the needs of the first and second correction pieces 82 and 83 to withstand certain loads during the lifting and correction process. At the same time, the Q235B carbon steel plate has good toughness and can absorb a certain amount of energy without brittle fracture when subjected to impact load, and is convenient to process.
[0030] In the embodiment, the distance between the upper corners of the two groups of second correction pieces 83 is equal to the distance between the upper corners of the two groups of first correction pieces 82, which ensures the accurate matching of the two groups in the spatial position, and then the first and second correction pieces 82 and 83 work together to realize the precise correction of the fixed frame 7. When the two groups of first correction pieces 82 enter the area between the two groups of second correction pieces 83, the distance between the upper corners of the two groups of second correction pieces 83 can just accommodate the two groups of first correction pieces 82, so that the two groups of first correction pieces 82 can be clamped into the area between the two groups of second correction pieces 83, and can guide and limit the first correction pieces 82, so that the fixed frame 7 is in the central position, and the correction of the weighing scale 1 is realized.
[0031] The working principle of the quick food weighing scale lifting and correction structure is as follows:
[0032] In actual use, when the height of the weighing scale 1 needs to be adjusted, the operator operates the hand-operated jack 4, which is the main power source for driving the lifting support 3 to move up and down, and pushes the lifting support 3 to move up and down along the integrated hanging frame 2. During the lifting process, the connecting hanging plate 9, the supporting frame 6, the fixed frame 7 and the weighing scale 1 move together with the lifting support 3. During the lifting process, due to various factors such as slight vibration of the lifting support 3, uneven stress, etc., the fixed frame 7 may have a tendency to deviate horizontally. When the fixed frame 7 has a tendency to deviate, the first and second correction pieces 82 and 83 begin to work. The first correction piece 82 is welded on the outer side of the connecting hanging plate 9 with the short side downward and the long side upward, and the second correction piece 83 is welded on the inner side of the positioning baffle 81 with the short side upward and the long side downward, and the long sides of the two are in contact with each other;
[0033] With the movement of the lifting support 3, when the two groups of first correction pieces 82 enter the area between the two groups of second correction pieces 83, the distance between the upper corners of the two groups of second correction pieces 83 can just accommodate the two groups of first correction pieces 82;
[0034] The long side surfaces of the first correction pieces 82 and the second correction pieces 83 are connected by mutual adhesion and resistance, and interact with each other. The first correction pieces 82 provide the second correction pieces 83 with inward and outward limiting force, and prevent the fixed frame 7 from deviating. For example, if the fixed frame 7 has a tendency to deviate to the left, the first correction pieces 82 on the left side will be closely adhered to the second correction pieces 83 on the left side, and through the friction force and structural limiting effect between the two, the fixed frame 7 is prevented from continuing to move to the left; similarly, the first correction pieces 82 and the second correction pieces 83 on the right side also limit the deviation on the right side. Through the interaction of the first correction pieces 82 and the second correction pieces 83, the two groups of first correction pieces 82 are always positioned between the two groups of second correction pieces 83, so as to correct the fixed frame 7, and further ensure that the weighing scale 1 is always in the central position, and the stability and weighing accuracy of the weighing scale 1 in the lifting process are ensured.
[0035] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made, and all the embodiments cannot be exhausted here. Any changes or variations derived from the technical solutions of the utility model still fall within the protection scope of the utility model.
