Description

A metal detection and weighing integrated machine Technical Field

[0001] This utility model relates to the field of metal detection technology, and in particular to an integrated metal detection and weighing machine. Background Technology

[0002] If food contains heavy metals such as copper, arsenic, chromium, mercury, and nickel, these heavy metals will accumulate in the body when the person consumes the food. When the heavy metal content exceeds the standard, it can lead to chronic heavy metal poisoning, thereby affecting the person's health.

[0003] Existing equipment for detecting heavy metals in food is usually a metal detector. Food is typically placed on a conveyor belt, which transports the food to the metal detector for testing. After the heavy metal test is completed, the food is manually labeled and then transported to a weighing machine to weigh the food to ensure that the weight meets a uniform standard.

[0004] In addition, equipment used for material transportation is usually complex in structure. Once common faults such as wear of the transmission belt or damage to the support plate occur, maintenance and cleaning work is extremely inconvenient. It often requires a lot of time and manpower to disassemble the entire frame or complex transmission mechanism, which will undoubtedly further increase the downtime and maintenance costs of the equipment, causing many inconveniences and economic losses to enterprises. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of the prior art and provide an integrated metal detection and weighing machine that can realize metal detection, weighing and rejection. At the same time, the transmission belt with this structure can be easily replaced, making it easy to clean and maintain.

[0006] To achieve the above objectives, the present invention adopts the following solution:

[0007] A metal detection and weighing integrated machine, comprising:

[0008] A transport device for transporting food along a predetermined route, wherein a metal detection mechanism is mounted at the front end of the transport device, a weighing mechanism is mounted in the middle of the transport device, and a rejection device is mounted at the rear end of the transport device to push the food onto a feeding device on one side of the transport device. The transport device includes multiple separately mounted conveyor lines, each conveyor line including a frame. Two connecting plates spaced apart are mounted on the frame, and a support plate assembly is connected between the two connecting plates. The support plate assembly is equipped with a drive belt and a drive assembly for driving the drive belt. The drive belt of the drive belt assembly is sleeved on the outside of the support plate assembly, and the support plate assembly can support the drive belt located above the support plate assembly.

A rotating plate that can be rotatably connected to the handle plate is provided with a downwardly protruding flange. When the handle plate and the rotating plate are in the locked position, the flange can press the extension downward, thereby locking the support plate assembly and the connecting plate.

[0011] The extension includes an extension post and a stop at the end of the extension post. The rotating plate is arc-shaped, and the flange is provided with an arc-shaped groove that allows the extension post to be inserted.

[0012] The support plate assembly includes a support plate and extension plates extending downward along the left and right sides of the support plate. Each of the extension portions is disposed on two of the extension plates, and a plurality of horizontal support rods capable of providing lateral support are disposed between the two extension plates.

[0029] The present invention will be further described in detail below with reference to embodiments:

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] As shown in Figures 1 to 10, a metal detection and weighing integrated machine includes: a transport device 1 for transporting food along a predetermined route; a metal detection mechanism 2 is mounted at the front end of the transport device 1; a weighing mechanism 3 is mounted in the middle of the transport device 1; and a rejection device 5 is mounted at the rear end of the transport device 1, capable of pushing the food onto a feeding device 4 on one side of the transport device 1. The transport device 1 includes multiple separately mounted conveyor lines 11, each conveyor line 11 including a frame 111. Two left-right spaced connecting plates 112 are mounted on the frame 111, and a support plate assembly 113 is connected between the two connecting plates 112. The support plate assembly 113 is equipped with a transmission belt 114 and a transmission assembly 115 for driving the transmission belt 114. The transmission belt 114 of the transmission belt assembly 114 is sleeved outside the support plate assembly 113, and the support plate assembly 113 can support the transmission belt 114 located above the support plate assembly 113. The support plate assembly 113 is detachably connected to the two connecting plates 112.

[0032] In use, the material moves along the conveyor device 1. By placing the metal detection mechanism 2 at the front, the weighing mechanism 3 in the middle, and the rejection device 5 at the rear, the invention can achieve an integrated and automated production line operation of detecting metal foreign objects, weighing, and rejecting defective products. The metal detection mechanism 2 at the front detects problematic products, the weighing mechanism 3 in the middle weighs and verifies the weight simultaneously, and the rejection device 5 at the rear accurately rejects them. Moreover, the conveyor device 1 is composed of multiple independent conveyor lines 11, and the support plate assembly 113 and the transmission belt 114 of each conveyor line 11 are detachably installed between the connecting plates 112 on both sides. When the transmission belt 114 is worn, needs cleaning, or the support plate assembly is damaged, it is not necessary to disassemble the entire frame or the complex transmission mechanism. It is only necessary to remove the support plate assembly 113 and the transmission belt 114 as a whole for maintenance, cleaning, or replacement.

[0033] The support plate assembly 113 is provided with an outwardly extending extension portion 1131, and the connecting plate 112 is provided with a locking position 1121 into which the extension portion 1131 can be engaged. A locking component 6 is provided between the connecting plate 112 and each extension portion 1131. The extension portion 1131 of the support plate assembly 113 and the locking position 1121 of the connecting plate 112 form a positioning engagement. During installation, the extension portion 1131 only needs to be slid into the locking position 1121 to complete the pre-positioning. The locking component 6 is used to lock the extension portion 1131 and the connecting plate 112 in a secure connection.

[0034] The locking assembly 6 includes a connecting seat 61, the connecting seat 61 is provided with a rotating shaft 62, a handle plate 63 that can be rotatably connected to the rotating shaft 62, a rotating plate 64 that can be rotatably connected to the handle plate 63, and a downwardly protruding flange 65 provided on the rotating plate 64. When the handle plate 63 and the rotating plate 64 are in the locked position, the flange 65 can press down on the extension 1131, thereby locking the support plate assembly 113 and the connecting plate 112.

[0035] When the handle plate 63 and the rotating plate 64 are in the locked position, the flange 65 on the rotating plate 64 can directly press down on the extension 1131 of the support plate assembly 113, ensuring that the support plate assembly 113 and the connecting plate 112 are firmly locked. Locking and unlocking actions can be achieved by rotating the handle plate 63 to drive the rotating plate 64; the operation is simple and intuitive, locking occurs when the handle plate 63 is rotated to the correct position. Reversing the rotation of the handle plate 63 and the rotating plate 64, causing the flange 65 to move away from the extension 1131, quickly releases the pressure on the extension 1131, and the locking force between the support plate assembly 113 and the connecting plate 112 disappears instantly, facilitating quick separation.

[0036] The extension 1131 includes an extension post 11311 and a stop 11312 disposed at the end of the extension post 11311. The rotating plate 64 is arc-shaped, and the flange 65 is provided with an arc-shaped slot 651 that allows the extension post 11311 to be inserted.

[0037] The arc-shaped slot 651 engages with the extension post 11311 for locking, while the stop part 11312 is limited in the vertical direction by the flange 65, completely preventing relative sliding between the support plate assembly 113 and the connecting plate 112 in the locked state.

[0038] The support plate assembly 113 includes a support plate 1132 and extension plates 1133 extending downward along the left and right sides of the support plate 1132. Each extension portion 1131 is disposed on two extension plates 1133, and a plurality of transverse braces 1134 for lateral support are disposed between the two extension plates 1133. The transverse braces 1134 form a transverse truss support between the extension plates 1133, which is used to enhance the structural strength of the support plate 1132 and the strength of supporting the two extension plates 1133, and to prevent the extension plates 1133 from tilting inward and deforming.

[0039] The transmission belt 114 includes a first transmission roller 1141 and a second transmission roller 1142 arranged at opposite ends, and a belt body 1143 capable of driving the first transmission roller 1141 and the second transmission roller 1142 is disposed between the first transmission roller 1141 and the second transmission roller 1142. When the first transmission roller 1141 and the second transmission roller 1142 rotate, the belt body 1143 can be rotated, thereby transporting the material on the belt body 1143.

[0040] The feeding device 4 includes a base frame 41, on which a feeding roller 42 is provided that can roll relative to it. In cooperation with the rejection device 5, defective products are fed out.

[0041] The rejection device 5 includes a mounting base 51 located on the conveyor line 11 at the rear end of the transport device 1. The mounting base 51 is equipped with a drive motor 52, and the output shaft of the drive motor 52 is equipped with a pusher plate 53 capable of pushing materials into the unloading device 4. When the drive motor 52 is started, the output shaft of the drive motor 52 drives the pusher plate 53 to move, causing the pusher plate 53 to move towards the conveyor line 11 and push the materials on the conveyor line 11 into the unloading device 4.

[0042] The transmission assembly 115 includes a rotary motor 1151 mounted on one of the two connecting plates 112. A rotary wheel 1152 is mounted on the output shaft of the rotary motor 1151. A driven wheel 1153 is mounted on the first transmission roller 1141. A belt 1155, capable of driving both the driven wheel 1153 and the driving wheel 1154, is positioned between them. A protective shell 7 is also mounted on the support plate assembly 113, and the driven wheel 1153, rotary wheel 1152, and belt 1155 are housed within the protective shell 7. When the rotary motor 1151 starts, it drives the rotary wheel 1152 to rotate. The rotation of the rotary wheel 1152 drives the belt 1155, which in turn drives the driven wheel 1153 to rotate. The rotation of the driven wheel 1153 drives the first transmission roller 1141 to rotate, thus activating the transmission belt 114 and enabling the movement of materials. The protective shell 7 is used to protect the rotating wheel 1152, driven wheel 1153, and tire 1155, and is dustproof, waterproof and impact-resistant.

[0043] Two positioning plates 81 are also provided on the conveyor line 11 at the front end of the conveyor device 1. A channel 82 for material to pass through is formed between the two positioning plates 81. The two positioning plates 81 are located inside the metal detection mechanism 2.

[0044] The channel 82 formed by the positioning plate 81 forces the material to pass through the metal detection mechanism 2 along the channel 82, which facilitates detection.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
