DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] A loss-in-weight food and medical grade weighing platform structure, such as Figure 1 , 2 As shown, it includes a closed housing 1, and a weighing sensor 2 is arranged inside the closed housing 1. Specifically, the closed housing 1 is a rectangular box-shaped structure, which includes an upper weighing platform 7, a side panel 8, and a lower sealing plate 9. The upper weighing platform 7 is vertically connected with side panels 8 around to form a receiving chamber 10. The receiving chamber 10 has a lower opening 11 opened downward. The lower sealing plate 9 is installed on the lower opening 11 to form a closed closed housing 1. A waterproof joint 12 is arranged on one side of the side panel. The internal structure for weighing includes the weighing sensor 2 being installed from the lower opening 11 into the closed housing 1. When the internal load-bearing structure is installed, the lower opening 11 is sealed so that a chamber with better sealing performance can be formed. Specifically, the lower edge of the side panel 8 is provided with an inverted edge 22, and a hexagonal head bolt 23 is arranged through the lower sealing plate 9 and the inverted edge 22. A silicone pad 24 is arranged between the inverted edge 22 and the lower sealing plate 9. The present structure adopts a fully enclosed structure with good dustproof performance and no dead corners. The weighed material will not enter the accommodating chamber 10, thereby preventing the material from affecting the weighing platform, nor will the material be hidden in the closed cover 1 and thus deteriorate and affect the production environment.

[0022] like Figure 1As shown, the two ends of the weighing sensor 2 are deformation transmission ends. In actual use, the weighing sensor 2 can use a pressure sensor. When the weight of the material placed on the upper weighing platform 7 causes the weighing sensor 2 to deform, and then the weighing sensor 2 converts the deformation into data and transmits it to the control system to complete the load-bearing operation of the material. Specifically, the first deformation transmission end 3 is connected to the upper plane, and the second deformation transmission end 4 is connected to the support part 5. The support part 5 is provided with a support foot 6 that passes through the lower end surface of the closed cover 1; the support foot 6 freely passes through the lower end surface of the closed cover 1. In actual use, when a heavy object is placed for weighing, the closed cover 1 will be pressed downward, while the position of the support part 5 remains unchanged, so that the support foot 6 passes through the closed cover 1, and the deformation amount generated on the weighing sensor 2 when the material is weighed is transmitted by this movable connection.

[0023] Specifically, Figure 2 As shown, through holes 13 are provided at the four corners of the lower sealing plate 9, and the supporting foot 6 passes through the through holes 13, and the diameter of the through holes 13 is slightly larger than the diameter of the supporting foot 6. The supporting foot 6 is made of rubber material. The diameter of the through hole 13 is slightly larger than the supporting foot 6, which not only allows the supporting foot 6 to move through it, but also the smaller gap can prevent materials from entering the interior. The support portion 5 includes a lower mounting plate 14, and the supporting foot 6 is fixedly provided on the lower end surface of the lower mounting plate 14. In addition, the mounting plate is on the upper side of the through hole 13, and the mounting plate can be used to block the gap formed between the through hole 13 and the supporting foot 6, which can effectively prevent materials from entering the accommodating chamber 10 and preventing it from affecting the weighing sensor 2.

[0024] A hard upper panel 15 is provided on the upper top surface of the inner side of the closed housing 1, and the upper panel 15, the lower mounting plate 14 and the weighing sensor 2 are all connected via a fixing structure 16. The upper panel 15 can be made of an iron plate with a certain thickness, so that the upper weighing table 7 will not be deformed when the weighing material is placed, and the gravity of the material can be fully transmitted to the first deformation transmission end 3, thereby improving the weighing accuracy.

[0025] like Figure 2 As shown, the fixing structure 16 includes a countersunk hole 17 formed on the upper panel 15 and the lower mounting plate 14, through which a hexagon socket bolt 18 is provided, and a pad 19 is provided between the upper panel 15, the lower mounting plate 14 and the weighing sensor 2, and the hexagon socket bolt 18 is inserted through the countersunk hole 17 and through the pad 19 and finally screwed on the weighing sensor 2. The fixing structures 16 arranged at both ends can fix the upper panel 15 and the lower mounting plate 14 respectively, and the fixing is firm, and the deformation transmission effect is good.

[0026] Furthermore, the upper panel 15 is connected to the upper weighing platform 7 by a round head square neck bolt 20, and the round head square neck bolt 20 is sequentially arranged through the upper weighing platform 7 and the upper panel 15 from top to bottom, and the round head thereof is blocked on the outer side of the upper weighing platform 7, and a sealing gasket 21 is arranged between the round head and the upper weighing platform 7. The upper weighing platform 7 and the upper panel 15 are locked and connected by the round head square neck bolt 20, which can improve the firmness of the fixation, and the round head is pressed on the upper weighing platform 7 by the sealing gasket 21, and the upper weighing platform 7 can also be sealed to prevent materials from entering.

[0027] It also includes a limit bolt 26, the lower sealing plate 9 is provided with a through hole 27 for the limit bolt 26 to pass through, and the lower mounting plate 14 is provided with a threaded hole 28 screwed with the limit bolt 26 at a corresponding position, and the limit bolt 26 passes through the through hole 27 and the threaded hole 28 in sequence, and its upper end is matched with the lower end surface of the weighing sensor 2. When in use, the limit bolt 26 can be screwed to form a gap of a certain distance between the upper end surface of the limit bolt 26 and the weighing sensor 2, thereby limiting the maximum deformation amplitude of the weighing sensor 2, thereby avoiding damage to the weighing sensor 2 when placing overweight materials.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
