DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figures 1-4 The belt type rodless rejection metal detector in the embodiment comprises a bracket 10, a detection part, a conveying part and a rejection part. The bracket 10 is provided with an alarm lamp 8. The bracket 10 is provided with a rejection assembly 7 for improving the rejection efficiency.

[0024] The rejection assembly 7 comprises a cylinder bracket 7.2 assembled on the bracket 10, a mounting plate 7.5 provided on the cylinder bracket 7.2, a rodless cylinder 7.1 assembled on the mounting plate 7.5, a cylinder slider 7.3 assembled on the piston rod of the rodless cylinder 7.1 and a push plate 7.4 assembled on the cylinder slider 7.3.

[0025] The detection part comprises a detection probe 5 provided on the bracket 10. The detection probe 5 is a common device in the prior art and is used to detect whether the product contains metal in the application. The detection probe 5 will not be described in detail herein. When the detection probe 5 detects that the product contains metal, the alarm lamp 8 will sound.

[0026] The conveying part comprises a motor 3 assembled on the bracket 10, a drive shaft 1 in transmission connection with the output shaft of the motor 3 through a chain and a chain wheel, a carrier roller 2 in transmission connection with the drive shaft 1 through a belt, a driven shaft 9 in transmission connection with the carrier roller 2 through a belt and a conveying belt 4 sleeved on the drive shaft 1 and the driven shaft 9.

[0027] The outer side of the output shaft of the motor 3 and the outer side of the drive shaft 1 are provided with chain wheels, which are in transmission connection through a chain.

[0028] The conveying belt 4 is provided with a supporting supporting plate 6, which is fixedly connected with the bracket 10.

[0029] In application, motor 3 is started, and the output shaft of motor 3 begins to rotate, driving the sprocket on its output shaft to rotate. Under the transmission action of the chain, the sprocket on the drive shaft 1 begins to rotate, which in turn drives the drive shaft 1 to rotate. Under the transmission action of the belt, the drive shaft 1 drives the idler roller 2 and the driven shaft 9 to rotate, finally causing the conveyor belt 4 to start moving. At this time, the metal detector can transport the product to be tested. Then, the product to be tested is placed on the moving conveyor belt 4. The conveyor belt 4 transports the product towards the detection probe 5. When the product passes through the detection probe 5, the detection probe 5 can detect whether the product contains metal.

[0030] Please see Figures 5-6 To improve rejection efficiency, the rejection component 7 in this embodiment includes a cylinder bracket 7.2 mounted on the bracket 10, a mounting plate 7.5 disposed on the cylinder bracket 7.2, a rodless cylinder 7.1 mounted on the mounting plate 7.5, a cylinder slider 7.3 mounted on the piston rod of the rodless cylinder 7.1, and a push plate 7.4 mounted on the cylinder slider 7.3.

[0031] It should be noted that the bracket 10 is equipped with a solenoid valve for controlling the start and stop of the rodless cylinder 7.1. The solenoid valve is connected to the detection probe 5. The installation of the rodless cylinder 7.1 saves installation space.

[0032] The cylinder slider 7.3 is slidably connected to the mounting plate 7.5 and the cylinder slider 7.3 is parallel to the mounting plate 7.5.

[0033] The push plate 7.4 is located below the mounting plate 7.5 and is used to reject products containing metal.

[0034] In application, when a product without metal passes through the detection probe 5, the detection probe 5 will not emit a signal, the rejection component 7 will not perform a rejection action, and the product will pass smoothly. When a product containing metal passes through the detection probe 5, the detection probe 5 emits a signal, which controls the rodless cylinder 7.1 to start through the solenoid valve, driving the cylinder slider 7.3 and push plate 7.4 to move towards the product containing metal, pushing the product containing metal out of the conveyor belt 4. After the push plate 7.4 moves, it will not return to its original position. It will only move in the opposite direction when there is a rejection signal again, pushing the product containing metal out of the conveyor belt 4.

[0035] The working principle of the above embodiments is as follows:

[0036] When the metal detector needs to inspect products, motor 3 is started first. The output shaft of motor 3 begins to rotate, driving the sprocket on its output shaft to rotate. Driven by the chain, the sprocket on drive shaft 1 begins to rotate, which in turn drives drive shaft 1 to rotate. Driven by the belt, drive shaft 1 drives idler roller 2 and driven shaft 9 to rotate, ultimately causing conveyor belt 4 to move. At this time, the metal detector can transport the products to be inspected. The products to be inspected are then placed on the moving conveyor belt 4. The conveyor belt 4 transports the products towards the inspection probe 5. As the product passes the inspection probe 5, the inspection probe... The probe 5 can detect whether the product contains metal. When a product without metal passes through the probe 5, the probe 5 will not emit a signal, the rejection component 7 will not perform a rejection action, and the product will pass through smoothly. When a product containing metal passes through the probe 5, the probe 5 emits a signal, which controls the rodless cylinder 7.1 to start through the solenoid valve. This drives the cylinder slider 7.3 and the push plate 7.4 to move towards the product containing metal, pushing the product containing metal out of the conveyor belt 4. After the push plate 7.4 moves, it will not return to its original position. It will only move in the opposite direction when there is a rejection signal again, pushing the product containing metal out of the conveyor belt 4.
