Description

Technical Field

[0001] This utility model relates to the field of food measurement technology, and in particular to a dynamic food weight measuring device. Background Technology

[0002] In food production, abnormal weight may be associated with quality issues. For example, underweight bagged snacks may be due to insufficient filling of raw materials, while overweight bottled sauces may be due to poor sealing leading to spillage. Checkweighers can detect these anomalies in a timely manner through dynamic measurement, reducing the influx of substandard products into the market. When conducting dynamic weight measurement and testing of food, there is a type of dynamic checkweigher available on the market. After the food is fed into the weighing area by a feeding conveyor belt, the weight causes the sensor to deform and convert it into an electrical signal. This signal is then converted into a digital signal by an AD converter. When the signal is stable, the microprocessor takes the average value as the actual weight and compares it with a preset standard value to determine whether it is qualified or not. Substandard products are separated by a rejection mechanism after positioning. At the same time, the system provides real-time data feedback and supports calibration to ensure accurate measurement.

[0003] Currently, when weighing food, a dynamic checkweigher is used to transport the food via a conveyor belt for dynamic measurement. However, the conveyor belt of this type of dynamic checkweigher often faces issues such as damaged food packaging bags or other food residues adhering to the food during weighing. These residues can easily affect the accuracy of dynamic weighing. Therefore, we propose a dynamic food weight measurement device. Utility Model Content

[0004] The main objective of this invention is to provide a dynamic food weight measuring device. A belt cleaning mechanism is installed on the dynamic checkweigher body. The vertical edge stopper of the belt cleaning mechanism, along with a rotating cleaning roller, contacts the conveyor belt of the dynamic checkweigher body via a brush roller sleeve, thereby brushing away residual food food on the conveyor belt surface. This facilitates convenient cleaning of the dynamic checkweigher body and prevents food residue from affecting the accurate weighing. Furthermore, the air cylinder of the belt cleaning mechanism periodically blows air onto the conveyor belt surface through an inclined flat tube, drying the food residue. Combined with the brush roller sleeve in contact with the conveyor belt, it can promptly remove dry or incompletely dried dirt from the conveyor belt surface, preventing the accumulation of residue before the conveyor belt is stopped for cleaning and resulting in false weights. This effectively solves the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dynamic food weighing device includes a dynamic checkweigher body, a conveyor belt installed between the bases of the dynamic checkweigher body, and a belt cleaning mechanism. The belt cleaning mechanism includes a vertical edge stop plate, a cleaning roller, a rotating column, a limiting plate, a brush roller sleeve, an air cylinder, a tail tube, and an inclined flat tube. The bases of the dynamic checkweigher body are bolted together with a vertical edge stop plate located below the conveyor belt. A rotating column is rotatably clamped at both sides of the vertical edge stop plate. A cleaning roller is clamped between the columns of the rotating column, and a retaining ring is fixed to the outside of the column extending out of the vertical edge stop plate. A limiting plate installed on the side of the vertical edge stop plate is clamped at the outer end of the rotating column away from the retaining ring. A brush roller sleeve is clamped and bonded to the outside of the cleaning roller. A tail tube is inserted into the inner surface of the vertical edge stop plate on one side of the cleaning roller. An air cylinder extending out of the vertical edge stop plate is installed on one side of the tail tube, and an inclined flat tube is integrally formed above the air cylinder, facing the brush roller sleeve and the conveyor belt.

[0007] Furthermore, the vertical plate of the vertical edge plug is locked on the outside of the base of the dynamic checkweigher body, and the vertical edge plug is locked to the base of the dynamic checkweigher body by bolts, and the opposing plate of the vertical edge plug is locked between the base of the dynamic checkweigher body.

[0008] By adopting the above technical solution, the vertical side plug can be installed on the outside of the base of the dynamic checkweigher body by means of bolts, and then the opposite plate of the vertical side plug can be inserted into the base of the dynamic checkweigher body for concealment.

[0009] Furthermore, a rotating hole is provided through the opposite plate of the vertical edge plug plate, and a rotating column is inserted through the rotating hole. An angle insert is fixed at one end of the rotating column, and angle slots for inserting the angle insert are provided at both ends of the cleaning roller.

[0010] By adopting the above technical solution, the rotating column can be inserted into the rotating hole, and then the cleaning roller can be placed between the vertical edge stop plates. Then, the rotating column can be inserted into the corner slots of the cleaning roller with the corner insert, so that the cleaning roller can rotate in the rotating hole in cooperation with the rotating column.

[0011] Furthermore, the diameter of the retaining ring is smaller than the diameter of the hole in the limiting ring plate, and an installation hole for screwing bolts is provided between the plate body of the limiting ring plate and the plate body of the vertical edge plug plate.

[0012] By adopting the above technical solution, after the rotating column is inserted into the rotating hole, the retaining ring on the outside of the column body can block the outside of the vertical edge plug plate. At the same time, the limiting plate can be fitted on the outside of the rotating column to press the retaining ring. Then, the limiting plate is installed by bolts to lock it on the outside of the vertical edge plug plate, ensuring the rotating column is prevented from detaching and rotating.

[0013] Furthermore, an insertion hole for inserting an air cylinder is provided through one side of the vertical side plug plate, and a connection hole for inserting a tail plug is provided on the other side of the vertical side plug plate. A threaded post welded to the tail end of the air cylinder is screwed into the cylinder body of the tail plug.

[0014] By adopting the above technical solution, after the air cylinder passes through the insertion hole of the vertical side stopper plate, a tail plug can be screwed on, and the tail plug can be inserted into the connection hole of the vertical side stopper plate for installation.

[0015] Furthermore, a sealing strip is inserted and bonded into the flat tube opening of the inclined flat tube, and a narrow slit for air venting is reserved between the inclined flat tube and the sealing strip.

[0016] By adopting the above technical solution, when the inclined flat tube is venting air, it can periodically blow air from the slit between the inclined flat tube and the sealing strip to the edge of the conveyor belt and the brush roller sleeve, thereby drying the adhering substances on the surface of the conveyor belt and making it easier for the adhering substances to be brushed off by the brush roller sleeve.

[0017] Furthermore, a receiving box located below the conveyor belt is welded between the opposing plates of the vertical edge plug plate away from the cleaning roller and the air cylinder, and the receiving box has an upward protruding slanted edge at the box body away from the cleaning roller.

[0018] By adopting the above technical solution, after the cleaning roller and brush roller sleeve brush off the stains on the surface of the conveyor belt, the dried stains can fall down into the collection box for collection.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model sets up a belt cleaning mechanism on the body of the dynamic checkweigher. The vertical edge plug plate of the belt cleaning mechanism carries a rotating cleaning roller that contacts the conveyor belt of the dynamic checkweigher body with a brush roller sleeve, thereby brushing away the food residue adhering to the surface of the conveyor belt, realizing convenient cleaning of the dynamic checkweigher body and avoiding the food residue adhering to the dynamic checkweigher body from affecting the accurate weighing of the dynamic checkweigher body.

[0021] Furthermore, the air cylinder of the belt cleaning mechanism blows air onto the surface of the conveyor belt periodically through the inclined flat tube, which can dry the food residue adhering to the surface of the conveyor belt. In conjunction with the brush roller sleeve that comes into contact with the conveyor belt, it can promptly brush away the dry or not completely dry dirt on the surface of the conveyor belt, preventing the adhering substances from accumulating and forming false weight before the conveyor belt stops for cleaning.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-3 As shown, a dynamic food weighing device includes a dynamic checkweigher body 1, a conveyor belt 2 installed between the bases of the dynamic checkweigher body 1, and a belt cleaning mechanism 3. The belt cleaning mechanism 3 includes a vertical edge stopper plate 4, a cleaning roller 6, a rotating column 9, a limiting plate 11, a brush roller sleeve 12, an air cylinder 15, a tail insert 16, and an inclined flat tube 17. The vertical edge stopper plate 4 located below the conveyor belt 2 is bolted between the bases of the dynamic checkweigher body 1, and the rotating column 9 is rotatably clamped at both sides of the vertical edge stopper plate 4. A cleaning roller 6 is clamped between the bodies, and a retaining ring 10 is fixed on the outside of the column body of the rotating column 9 that extends out of the vertical edge stopper plate 4. A limiting ring plate 11 installed on the side of the vertical edge stopper plate 4 is clamped at the outer end of the rotating column 9 away from the retaining ring 10. A brush roller sleeve 12 is clamped and bonded to the outside of the roller body of the cleaning roller 6, and a tail insert 16 is inserted into the inner surface of the vertical edge stopper plate 4 on one side of the cleaning roller 6. An air cylinder 15 that extends out of the vertical edge stopper plate 4 is installed on one side of the tail insert 16, and an inclined flat tube 17 that faces the brush roller sleeve 12 and the conveyor belt 2 is integrally formed on the top of the cylinder body of the air cylinder 15.

[0028] The vertical plate of the vertical edge plug 4 is locked on the outside of the seat of the dynamic checkweigher body 1, and the vertical edge plug 4 and the seat of the dynamic checkweigher body 1 are locked together by bolts. The opposing plate of the vertical edge plug 4 is inserted between the seats of the dynamic checkweigher body 1.

[0029] By adopting the above technical solution, the vertical edge plug 4 can be installed on the outside of the seat of the dynamic checkweigher body 1 by means of bolts. Then, the opposite plate of the vertical edge plug 4 can be inserted into the seat of the dynamic checkweigher body 1 and hidden.

[0030] Among them, the vertical edge plug plate 4 has a through hole 5 through the opposite plate body, and a rotating column 9 is inserted through the hole 5. An angle insert 8 is fixed at one end of the column body of the rotating column 9, and the two ends of the cleaning roller 6 have angle slots 7 for inserting the angle insert 8.

[0031] By adopting the above technical solution, the rotating column 9 can be inserted into the rotating hole 5, and then the cleaning roller 6 can be placed between the vertical edge plug plates 4. Then the rotating column 9 can be inserted into the corner slots 7 of the cleaning roller 6 with the corner insert 8, so that the cleaning roller 6 can rotate in the rotating hole 5 in cooperation with the rotating column 9.

[0032] Wherein, the diameter of the retaining ring 10 is smaller than the diameter of the ring hole of the limiting ring plate 11, and an installation hole for screwing bolts is provided between the plate body of the limiting ring plate 11 and the plate body of the vertical edge plug plate 4.

[0033] By adopting the above technical solution, after the rotating column 9 is inserted into the rotating hole 5, the retaining ring 10 on the outside of its column body can block the outside of the vertical edge plug plate 4. At the same time, the limiting ring plate 11 can be fitted on the outside of the rotating column 9 to press the retaining ring 10. Then, the limiting ring plate 11 is installed by bolting to the outside of the vertical edge plug plate 4 to ensure the rotation of the rotating column 9 is prevented from detaching.

[0034] The vertical side plug plate 4 has an insertion hole 13 for inserting the air cylinder 15 through one side plate, and a connection hole 14 for inserting the tail plug 16 is provided on the other side plate. The tail plug 16 has a threaded post welded to the tail end of the air cylinder 15 screwed into its cylinder.

[0035] By adopting the above technical solution, the air cylinder 15 can be screwed onto the tail plug 16 after passing through the insertion hole 13 of the vertical side plug plate 4, and the tail plug 16 can be inserted into the connection hole 14 of the vertical side plug plate 4 for installation.

[0036] The inclined flat tube 17 has a sealing strip 18 inserted and bonded inside its flat tube opening, and a narrow slit for air venting is reserved between the inclined flat tube 17 and the sealing strip 18.

[0037] By adopting the above technical solution, when the inclined flat tube 17 is venting air, it can periodically blow air from the slit between the inclined flat tube 17 and the sealing strip 18 to the edge of the conveyor belt 2 and the brush roller sleeve 12, thereby drying the adhering substances on the surface of the conveyor belt 2 and making it easier for the adhering substances to be brushed off by the brush roller sleeve 12.

[0038] Among them, the vertical edge plug plate 4 is welded to the opposite plate body away from the cleaning roller 6 and the air cylinder 15, and the receiving box 19 located below the conveyor belt 2 is welded between them, and the receiving box 19 has an upward sloping edge protruding from the box body away from the cleaning roller 6.

[0039] By adopting the above technical solution, after the cleaning roller 6 and the brush roller sleeve 12 brush off the stains on the surface of the conveyor belt 2, the dried stains can fall down into the receiving box 19 for collection.

[0040] It should be noted that this utility model is a dynamic food weight measuring device. A cleaning mechanism 3 is installed on the main body 1 of the dynamic checkweigher. The cleaning roller 6 of the cleaning mechanism 3 is inserted between the vertical side stoppers 4. Then, the rotating column 9 passes through the rotating hole 5 of the vertical side stopper 4, so that the corner inserts 8 of the rotating column 9 are inserted into the corner slots 7 at both ends of the cleaning roller 6. After the rotating column 9 passes through the rotating hole 5, the retaining ring 10 on the outside of its column body can block the outside of the vertical side stopper 4. At the same time, the limiting plate 11 can be fitted around the outside of the rotating column 9 to press the retaining ring 10. Subsequently, the limiting plate 11 is locked to the outside of the vertical side stopper 4 by bolts. After installation, the air cylinder 15 passes through the insertion hole 13 of the vertical side plug plate 4 and is screwed onto the tail plug 16. The tail plug 16 is then inserted into the connection hole 14 of the vertical side plug plate 4 for installation. At this time, the vertical side plug plate 4, along with the connection box 19, is inserted between the base of the dynamic checkweigher body 1. The vertical plate of the vertical side plug plate 4 is then locked to the outside of the base of the dynamic checkweigher body 1 with bolts. An air compressor supply pipe controlled by an air valve can be screwed onto the cylinder opening of the air cylinder 15. Under the guidance of the electrical technicians of the air compressor manufacturer, the air cylinder 15 can be connected to the power control to achieve periodic air supply.

[0041] When food is placed on the conveyor belt 2 of the dynamic checkweigher body 1 and encounters dirt during dynamic weighing and detection, the dirt will travel along the conveyor belt 2 through the inclined flat tube 17 of the air cylinder 15. Subsequently, when air is supplied from the air cylinder 15, the gas can be blown along the inclined flat tube 17 to one side of the surface of the conveyor belt 2 for drying. When the dried or not completely dried dirt passes through the brush roller sleeve 12 in contact with the conveyor belt 2, the dirt will be brushed off. Some of the dried dirt will fall into the collection box 19 for collection, while some dirt will be brushed off and collected by the brush roller sleeve 12. Workers can periodically remove the bolts between the vertical edge stopper plate 4 and the lower seat of the dynamic checkweigher body 1 to disassemble the belt cleaning mechanism 3 for periodic cleaning.
