Description

Technical Field

[0001] The present application relates to the technical field of steel ball production and packaging, and in particular to a steel ball weighing device. Background Art

[0002] Bearing steel balls are small spheres made of chrome steel or carbon steel, usually spherical or cylindrical in shape. They are placed in the steel ball holder inside the bearing. Steel balls are one of the key components of the bearing. The packaging process of bearing steel balls generally includes a series of processes such as cleaning, collecting, counting, weighing, bagging, boxing, labeling, and shipping.

[0003] In the production process of steel balls, the steel balls need to be weighed and bagged before being packed in boxes to ensure that the weight of each package of bearing steel balls is within a reasonable error range. The existing weighing method is that the operator uses a bag to catch the steel balls at the discharge port of the counting process, and after visually observing that the steel balls reach a certain weight, the bag is transferred to the weighing equipment for weighing. If the weight is overweight, some steel balls are poured out, and if the weight is insufficient, steel balls are added to the bag, so that the weight of each package of bearing steel balls is within a reasonable error range.

[0004] The above-mentioned method of weighing the steel balls manually has large errors and low accuracy due to visual measurement. The operator needs to weigh and add or reduce the weight of the steel balls repeatedly to ensure that the weight of each package of bearing steel balls is within a reasonable error range, which is time-consuming and labor-intensive and leads to low production efficiency. Utility Model Content

[0005] In order to help solve the problem that manual bagging requires repeated weighing of steel balls, which is time-consuming and labor-intensive and leads to low production efficiency, the present application provides a steel ball weighing device, which adopts the following technical solution: it includes a base, a weighing slot is provided on the base, a number of steel balls are placed in the weighing slot, a weighing unit for weighing the base is provided on the surface of the base facing away from the weighing slot, an interception unit is provided on the base for intercepting the steel balls in the weighing slot, and the interception unit is arranged at the outlet end of the weighing slot.

[0006] Through the above technical scheme, the steel balls are fed into the weighing slot of the base, and the weighing unit weighs the base as a whole. When the weight of the steel balls in the weighing slot reaches the set value, the intercepting unit is started to discharge the steel balls from the outlet end of the weighing slot for subsequent bagging and packaging operations. By using the weighing unit and the intercepting unit, there is no need for operators to repeatedly bag and weigh the steel balls, which reduces labor costs, has high accuracy, saves time and effort, and improves production efficiency.

[0007] In a specific possible implementation manner, the weighing unit includes a weighing scale arranged at the bottom of the base, and the weighing scale is connected to the base through a supporting assembly.

[0008] Through the above technical solution, when the steel ball enters the weighing trough, the overall weight of the base will increase. The base will transfer the increased weight to the weighing scale through the supporting assembly. The weighing scale will give feedback and measure the weight of the steel ball in the weighing trough at the same time. The weighing accuracy is high and the production efficiency is improved.

[0009] In a specific possible implementation scheme, the support assembly includes a support frame arranged on the weighing scale, the end of the support frame facing away from the weighing scale is arranged on the base, and the support frame is inclined from the inlet end of the weighing tank toward the outlet end of the weighing tank.

[0010] Through the above technical solution, the inclined support frame sets the base in an inclined state, and the steel balls can roll out along the inclined base, which is convenient for smooth discharge and bagging of the steel balls after weighing, saving time and labor while improving production efficiency.

[0011] In a specific feasible implementation scheme, a mounting hole is provided on the support frame, a mounting bolt matching the mounting hole is passed through the mounting hole, a mounting groove matching the mounting bolt is provided on the weighing scale, and the mounting bolt is threadedly connected in the mounting groove.

[0012] Through the above technical solution, the operator can remove the support base from the weighing scale by disassembling the bolts, and then replace different types of support frames to adjust the angle of the base relative to the weighing scale, which is more flexible.

[0013] In a specific possible implementation manner, the mounting hole is a waist-shaped hole.

[0014] Through the above technical solution, the waist-shaped hole makes it easy for the operator to adjust the position of the support frame relative to the weighing scale, thereby improving the flexibility of the support frame.

[0015] In a specific feasible implementation scheme, the interception unit includes two support rods arranged on a base, a support plate is provided between the two support rods, a first cylinder is provided on the surface of the support plate facing the base, a material baffle plate matching the weighing trough is provided at the output end of the first cylinder, and the two support rods pass through the material baffle plate; when the interception unit is in the interception state, one end of the material baffle plate facing the base contacts the bottom of the weighing trough.

[0016] Through the above technical solution, the two support rods pass through the baffle plate to limit the position of the baffle plate, reducing the possibility of the baffle plate deflecting. Start the first cylinder, the first cylinder drives the baffle plate at the output end to move up and down, and the baffle plate intercepts the steel ball in the weighing trough when it contacts the bottom of the weighing trough. When the baffle plate is lifted, the steel ball is discharged from the gap between the baffle plate and the bottom of the weighing trough. The interception unit is used to facilitate the control of the steel ball in the weighing trough, reducing the possibility of the steel ball rolling out of the weighing trough due to external force during the weighing process.

[0017] In a specific possible implementation, mounting frames are respectively provided on both sides of the base, a brush frame is connected between the two mounting frames via a lifting assembly, and a plurality of roller brushes matching the weighing slots are rotatably connected to the brush frame.

[0018] Through the above technical solution, the bouncing steel ball contacts the roller brush when entering the weighing trough. The roller brush has a damping effect on the feeding steel ball, reducing the speed and amplitude of the rolling of the steel ball, improving the stability of the steel ball when entering the weighing trough, and facilitating the weighing of the steel ball on the weighing scale.

[0019] In a specific possible implementation manner, the lifting assembly includes two second cylinders respectively arranged on two mounting frames, and the vertical frame is arranged between the output ends of the two second cylinders.

[0020] Through the above technical solution, the second cylinder is started, and the second cylinder drives the vertical frame to rise and fall, so that the distance between the roller brush on the vertical frame and the weighing slot can be adjusted, so that the roller brush can handle steel balls of different models and sizes.

[0021] In a specific possible implementation manner, a baffle is provided on the wall of the weighing trough, and the baffle partially extends out of the weighing trough.
