Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of food and drug weighing, and particularly relates to an adjusting anchor bolt device for a weighing module. Background Art
[0002] A weighing sensor device is actually a device that converts a mass signal into a measurable electrical signal output. When using a sensor, the actual working environment where the sensor is located should be considered first, which is crucial for correctly selecting a weighing sensor. It is related to whether the sensor can work normally, its safety and service life, and even the reliability and safety of the entire balancer. Currently, weighing modules are commonly used to measure the discharging / feeding weight of food and drug production metering storage tanks and batching tanks. Due to the stirring or vibration of the tank body, situations such as the offset of the weighing module often occur, resulting in inaccurate weighing and damage to the weighing sensor. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an adjusting anchor bolt device for a weighing module with a simple structure, convenient operation, low cost, and good applicability.
[0004] The technical solution provided by the utility model is: an adjusting anchor bolt device for a weighing module, including a weighing module fixing plate, an adjusting bolt, a limiting block, and an adjusting nut. A through hole is processed in the center of the weighing module fixing plate. The lower end of the limiting block is inserted into the through hole in the center of the weighing module fixing plate. The limiting block cannot rotate relative to the weighing module fixing plate. The outer wall of the limiting block is provided with a convex platform, and the lower end surface of the convex platform abuts against the weighing module fixing plate. On the one hand, it limits the depth of insertion of the limiting block into the weighing module fixing plate. On the other hand, the limiting block and the weighing module fixing plate form surface-to-surface contact, increasing the contact area, which can resist the influence of lateral force on the sensor caused by stirring or vibration, and the weighing module has good stability. The lower part of the adjusting bolt slides and inserts into the center of the limiting block and can rotate freely relative to the limiting block. A clutch sleeve is sleeved in the middle of the adjusting bolt. The clutch sleeve can slide relative to the adjusting bolt but cannot rotate relative to the adjusting bolt. After the clutch sleeve slides downward, it can be inserted into the limiting block. After insertion, the clutch sleeve and the limiting block cannot rotate relative to each other, and then the adjusting bolt cannot rotate relative to the weighing module fixing plate. The adjusting nut is screwed onto the uppermost part of the adjusting bolt, and the adjusting nut is welded to the storage tank support leg or the powder bin support ear. The number of the adjusting nuts is the same as the number of the storage tank support legs. The levelness of the equipment to be weighed can be adjusted through the adjusting bolt.
[0005] A further technical solution is: the lower end of the limiting block is processed with a chamfer to facilitate insertion into the through hole in the center of the weighing module fixing plate.
[0006] A further technical solution is as follows: external teeth are machined on the inner side of the lower end of the clutch sleeve, and internal teeth are machined on the outer side of the upper end of the limit block. The external teeth at the lower end of the clutch sleeve are inserted into the internal teeth at the upper end of the limit block, so that the clutch sleeve and the limit block cannot rotate relative to each other after being inserted.
[0007] A further technical solution is as follows: the outer side of the clutch sleeve has a jaw surface of a monkey wrench, which facilitates using the monkey wrench to rotate the clutch sleeve.
[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0009] 1. The utility model can conveniently adjust the levels of the tank body and the silo body, and can ensure the accuracy and durability of the weighing sensor under the condition of stirring or vibration, and is applicable to the weighing production process in food and drug processing in cooperation with the weighing module.
[0010] 2. The utility model can not only rotate the adjusting bolt through the clutch sleeve, but also lock the adjusting bolt in place. When it is necessary to rotate the adjusting bolt, push the clutch sleeve upward and rotate the clutch sleeve with a monkey wrench, so as to rotate the adjusting bolt; after the adjustment is completed, push the clutch sleeve downward to make it inserted with the limit block, thereby restricting the rotation of the clutch sleeve relative to the limit block, and further restricting the rotation of the adjusting bolt relative to the weighing module fixing plate. The significance of restricting the rotation of the adjusting bolt is to prevent the adjusting bolt from rotating when the tank body and the silo body are stirred and vibrated, resulting in the tank body and the silo body being unlevel again.

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0017] Referring to Figure 1 , this embodiment is an adjusting anchor bolt device for a weighing module, and its structure includes a weighing module fixing plate 1, an adjusting bolt 4, a limiting block 2 and an adjusting nut 5. A through hole is processed in the center of the weighing module fixing plate 1, and the lower end of the limiting block 2 is inserted into the through hole in the center of the weighing module fixing plate 1 with a gap, but the limiting block 2 cannot rotate relative to the weighing module fixing plate 1. The outer wall of the limiting block 2 is provided with a boss 201, and the lower end surface of the boss 201 abuts against the weighing module fixing plate 1. On the one hand, it limits the depth of the limiting block 2 inserted into the weighing module fixing plate 1, and on the other hand, the limiting block 2 and the weighing module fixing plate 1 form surface-to-surface contact, increasing the contact area, which can resist the influence of lateral force of stirring or vibration on the sensor, and making the weighing module have good stability. The lower part of the adjusting bolt 4 slides into the center of the limiting block 2 and can rotate freely relative to the limiting block 2. A clutch sleeve 3 is sleeved in the middle of the adjusting bolt 4. The clutch sleeve 3 can slide relative to the adjusting bolt 4 but cannot rotate relative to the adjusting bolt 4. After the clutch sleeve 3 slides down, it can be inserted into the limiting block 2. After insertion, the clutch sleeve 3 and the limiting block 2 cannot rotate relative to each other, and then the adjusting bolt 4 cannot rotate relative to the weighing module fixing plate 1. The adjusting nut 5 is screwed on the uppermost part of the adjusting bolt 4, and the adjusting nut 5 is welded to the storage tank leg or the powder silo support ear 6. The number of the adjusting nuts 5 is the same as the number of the storage tank legs or the powder silo support ears 6. The levelness of the storage tank or the silo to be weighed can be adjusted by the adjusting bolt 4.
[0018] When it is necessary to rotate the adjusting bolt 4, push the clutch sleeve 3 upward, and rotate the clutch sleeve 3 with a wrench, so as to rotate the adjusting bolt 4. Since the adjusting nut 5 is fixed, the height of the storage tank leg or the powder silo support ear 6 is adjusted. After the adjustment is completed, push the clutch sleeve 3 downward so that it is inserted into the limiting block 2, thereby restricting the rotation of the clutch sleeve 3 relative to the limiting block 2, and further restricting the rotation of the adjusting bolt 4 relative to the weighing module fixing plate 1. The significance of restricting the rotation of the adjusting bolt 4 is to prevent the adjusting bolt 4 from rotating during the stirring and vibration of the tank body or the silo body, resulting in the tank body or the silo body being unlevel again.
[0019] A chamfer is processed at the lower end of the limiting block 2 to facilitate insertion into the through hole in the center of the weighing module fixing plate 1.
[0020] As Figure 2As shown, external teeth are machined on the inner side of the lower end of the clutch sleeve 3, and internal teeth are machined on the outer side of the upper end of the limit block 2. The external teeth at the lower end of the clutch sleeve 3 are inserted into the internal teeth at the upper end of the limit block 2, so that the clutch sleeve 3 and the limit block 2 cannot rotate relative to each other after being inserted.
[0021] As Figure 2 shown, the outer side of the clutch sleeve 3 has a surface for a monkey wrench, which is convenient for using a monkey wrench to rotate the clutch sleeve 3.
[0022] As Figure 3 shown, at the mating part of the clutch sleeve 3 and the adjusting bolt 4, a plane is cut out on the cylindrical adjusting bolt 4, and a corresponding plane is also provided on the inner side of the clutch sleeve 3, so that the clutch sleeve 3 can only slide axially relative to the adjusting bolt 4 and cannot rotate.
[0023] As Figure 4 shown, the cross-section of the lower end of the limit block 2 can be in the shape of a plum blossom, and the through hole of the weighing module fixing plate 1 is also designed in the corresponding plum blossom shape. After the limit block 2 is inserted into the through hole of the weighing module fixing plate 1, the relative rotation of the two is limited. Of course, this is only one form of the present application. As long as the structure in which the limit block 2 cannot rotate relative to the weighing module fixing plate 1 belongs to the protection scope of the present application.
[0024] The utility model can conveniently adjust the non-levelness of the tank body and the silo body caused by the non-levelness of the civil engineering ground on site. At the same time, since the lower parts of the weighing module fixing plate 1 and the limit block 2 are inserted and matched, the weighing module can be effectively prevented from shifting due to the stirring or vibration of the tank body. The levelness of the tank body and the silo body to be measured is good, and the gravity can be vertically transmitted to the weighing sensor 7.
