[0004] In the above device, the feeding mechanism feeds the powder into the weighing hopper for weighing. During the weighing process, since the feeding mechanism does not have a limiting structure, some powder still enters when the weight inside the weighing hopper reaches the requirement, thus affecting the weighing accuracy. At the same time, in the above device, due to weighing the powder, a certain amount of dust will be generated when the powder enters the weighing hopper, thus affecting the weighing environment. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a weighing device for automotive brake pad pressing powder, which solves the problems that the feeding device of the existing weighing device for automotive brake pad pressing powder does not have a limiting structure when in use, thus affecting the weighing accuracy and the dust generated by the powder during the weighing process scatters and affects the working environment.

[0006] To achieve the above object, the utility model provides the following technical solution: A weighing device for automotive brake pad pressing powder, including a base, a bracket is arranged on one side above the base, a mounting seat is arranged above the bracket, a housing is arranged above the mounting seat, a discharge port is arranged inside the housing, and a feed bin is arranged on one side above the housing;

[0007] A feeding mechanism is arranged inside the housing, a dust collection mechanism is arranged on one side of the feeding mechanism, and a weighing mechanism is arranged below the dust collection mechanism;

[0009] As a preferred technical solution of the present invention, the dust collection mechanism includes a dust collection cover, a through hole, a fan and a dust collection pipe. A through hole is opened on one side of the surface of the dust collection cover, and a dust collection pipe is fixedly connected above the fan.

[0010] As a preferred technical solution of the present invention, the weighing mechanism includes a fixing ring, a connecting plate, a weighing sensor and a hopper. The weighing sensor is fixedly installed on the upper surface of the fixing ring, and the connecting plate is fixedly installed on the outer surface of the hopper.

[0011] As a preferred technical solution of the present invention, the bracket is fixedly installed on both sides of the upper surface of the base. A housing is fixedly installed inside the upper part of the mounting seat. Below the discharge port opened on one side inside the housing is fixedly connected to a discharge pipe.

[0012] As a preferred technical solution of the present invention, the motor is fixedly installed with the housing. The screw rod is in contact with the inner wall of the housing. The limiting rod is sleeved inside the housing. The limiting plate is fixedly connected to the limiting rod, and the limiting plate does not contact the screw rod.

[0013] As a preferred technical solution of the present invention, the dust collection cover is located above the weighing mechanism and does not contact it.

[0015] Compared with the prior art, the present invention provides an automotive brake pad pressing powder weighing device, which has the following beneficial effects:

[0016] 1. The weighing device for pressing powder of automotive brake pads drives the auger rod to rotate through the feeding mechanism installed inside the housing. As a result, the powder inside the housing is pushed towards the discharge port. Due to the movement of the powder, the limiting plate is pushed to move by the powder, thus exposing the discharge port. Consequently, the powder can enter the hopper through the discharge port and the discharge pipe for weighing. When the weighing sensor senses that the weight reaches the set value, the controller can control the motor to shut down. Since the motor shuts down, the auger rod stops rotating. Then, under the reaction force of the return spring, the limiting plate moves to limit the discharge port, preventing the powder from entering the hopper again and affecting the weighing accuracy.

[0017] 2. The weighing device for pressing powder of automotive brake pads is equipped with a dust collection pipe installed above the housing. The dust collection pipe is fixedly connected to the fan. Meanwhile, a dust collection cover is fixedly installed below the fan, and the dust collection cover is located above the hopper. Therefore, when the powder enters the hopper, the generated dust can be sent into the dust collection pipe by starting the fan and then sent back into the housing through the dust collection pipe. Thus, this device can effectively avoid dust dispersion and also reduce the waste generated during powder weighing. Description of the Drawings

Detailed Embodiment

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , in this implementation: A weighing device for automotive brake pad pressing powder includes a base 1. A bracket 2 is provided on one side above the base 1. A mounting seat 3 is provided above the bracket 2. A housing 6 is provided above the mounting seat 3. An outlet 8 is provided inside the housing 6. A feed bin 9 is provided on one side above the housing 6;

[0025] An upper feeding mechanism 4 is provided inside the housing 6. A dust collection mechanism 5 is provided on one side of the upper feeding mechanism 4. A weighing mechanism 7 is provided below the dust collection mechanism 5;

[0026] The upper feeding mechanism 4 includes a motor 41, a screw rod 42, a limiting rod 43, a return spring 44, and a limiting plate 45. The screw rod 42 is driven and connected to one side of the motor 41. The return spring 44 is sleeved outside the limiting rod 43. One side of the return spring 44 is fixedly connected to the limiting plate 45.

[0027] Please refer to Figure 1 and Figure 3 , in this embodiment, the dust collection mechanism 5 includes a dust collection cover 51, a through hole 52, a fan 53, and a dust collection pipe 54. A through hole 52 is opened on one side of the surface of the dust collection cover 51. The dust collection pipe 54 is fixedly connected above the fan 53.

[0028] In the above embodiment, under the action of the fan 53, the dust blocked by the dust collection cover 51 can be sent into the dust collection pipe 54 when the fan 53 is started. Since the dust collection pipe 54 is connected to the housing 6, the dust enters the inside of the housing 6.

[0029] Specifically, the dust collection cover 51 is located above the weighing mechanism 7 and does not contact it. A discharge pipe is sleeved inside the through hole 52. The fan 53 is fixedly installed with the dust collection cover 51. Both ends of the upper part of the dust collection pipe 54 are fixedly installed with the housing 6. The dust collection pipe 54 is a metal pipe.

[0030] Since the dust collection cover 51 is located above the weighing mechanism 7, the dust collection cover 51 will not affect the initial weight of the weighing mechanism 7. And since the power of the fan 53 is relatively low, the fan 53 will not extract the powder inside the weighing mechanism 7, but only extract the dust inside the dust collection cover 51.

[0031] Please refer to Figure 1 andFigure 4 , in this embodiment, the weighing mechanism 7 includes a fixed ring 71, a connecting plate 72, a weighing sensor 73, and a hopper 74. The weighing sensor 73 is fixedly installed on the upper surface of the fixed ring 71, and the connecting plate 72 is fixedly installed on the outer surface of the hopper 74.

[0032] In the above embodiment, the weighing mechanism 7 is installed and fixed to the bracket 2 by the action of the fixed ring 71, and the connecting plate 72 fixedly installed on the outside of the hopper 74 can be installed with the cooperation of the fixed ring 71 and the weighing sensor 73 to install the hopper 74.

[0033] Furthermore, the fixed ring 71 is fixedly installed between the bracket 2 and the mounting seat 3. There are three groups of both the connecting plate 72 and the weighing sensor 73, and they are respectively arranged in a surrounding manner on the outer surface of the hopper 74 and the upper surface of the fixed ring 71.

[0034] Under the installation action of the connecting plate 72 and the weighing sensor 73, when the powder enters the inside of the hopper 74, the weight can be transmitted to the weighing sensor 73. By the change of the value of the weighing sensor 73, subtracting the self-weights of the hopper 74 and the connecting plate 72 can obtain the weight of the powder.

[0035] Please refer to Figure 1 and Figure 2 , in this embodiment, the motor 41 is fixedly installed with the housing 6, the auger rod 42 is in contact with the inner wall of the housing 6, the limiting rod 43 is sleeved inside the housing 6, the limiting plate 45 is fixedly connected with the limiting rod 43, and the limiting plate 45 does not contact the auger rod 42.

[0036] In the above embodiment, the powder can be sent to the discharge port 8 through the auger rod 42 under the action of the motor 41. Due to the movement of the powder, the limiting plate 45 moves outward, so that the discharge port 8 can be exposed, and the powder can enter the inside of the weighing mechanism 7 through the discharge pipe.

[0037] It should be supplemented that the bracket 2 is fixedly installed on both sides of the upper surface of the base 1. The housing 6 is fixedly installed inside the upper part of the mounting seat 3. There is a discharge port 8 opened on the lower side of one side inside the housing 6, and a discharge pipe is fixedly connected below the discharge port 8. Through the discharge pipe installed below the discharge port 8 and the discharge pipe not contacting the weighing mechanism 7, the powder can enter the weighing mechanism 7 for weighing.

[0038] Working principle and usage process of the utility model: The operator feeds the powder into the interior of the housing 6 through the feed bin 9. Under the action of the motor 41, the auger rod 42 rotates, thereby pushing the powder to the position of the discharge port 8. Due to the movement of the powder, the limit plate 45 is pushed outward and the return spring 44 is compressed, so that the discharge port 8 is exposed, and the powder enters the interior of the hopper 74 through the discharge port 8 and the discharge pipe. The powder is weighed through the cooperation of the connecting plate 72 installed outside the hopper 74 and the weighing sensor 73. When the powder enters the hopper 74, certain dust will be generated. The dust is collected by the dust collection cover 51, and under the action of the fan 53, the collected dust is sent into the interior of the housing 6 through the dust collection pipe 54. When the powder reaches the set weight, the background controller can be started through the weighing sensor 73 to control the motor 41 to stop, so that the auger rod 42 stops rotating. Since the auger rod 42 stops, the powder stops moving, and then under the reaction force of the return spring 44, the limit plate 45 moves inward, thereby limiting the discharge port 8 to prevent the powder from falling again.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
