Description

Technical Field

[0001] This utility model relates to a metal detection device for the production of simulated long-pile fabric. Background Technology

[0002] Plush toys are beloved by children, and they are ubiquitous in households with children. Plush toys come in long-haired and short-haired varieties, but regardless of the type, they are all made by sewing and stuffing corresponding fabrics. However, during the sewing and cutting process, broken needles and metal fragments from sewing machines or cutting devices can become embedded in the fabric, potentially injuring children. Therefore, it is necessary to design a metal detection device to address this issue, primarily to detect broken needles and metal fragments in the fabric, preventing these sharp metal objects from injuring consumers.

[0003] However, most existing metal detection devices use fixed-angle probes, such as single-point detection at the top, which cannot cover the sides and deep areas of fluffy, long-haired fabrics. They are prone to missing embedded broken needles or metal fragments. Furthermore, the fixed-height detection mechanism is prone to mechanical interference with thick fabrics, requiring frequent shutdowns for adjustment. It cannot adapt to stacked fabrics for detection, thus failing to improve detection efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a metal detection device for simulating the production of long-pile fabrics.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A metal detection device for producing simulated long-pile fabric includes a frame, a conveying mechanism mounted on the frame, a drive motor mounted on one side of the conveying mechanism, a metal detection mechanism mounted on the frame and cooperating with the conveying mechanism, and a PLC control box mounted below the frame and connecting the drive motor and the metal detection mechanism. The metal detection mechanism includes two identical support legs, a side metal detection head embedded in the upper inner side of the support legs, a top cover located above the two support legs and supported by the support legs, a lifting cylinder fixedly mounted with the support legs and the top cover, a rotary motor fixedly mounted on one side of the top cover, and a top rotating detection component embedded in the lower end of the top cover and connected to the output end of the rotary motor.

[0007] Preferably, the support base is located on both sides of the conveying mechanism and is fixedly installed with the frame, and a vertical groove for embedding the side metal detector head is provided on the upper inner side of the support foot.

[0008] Preferably, a horizontal plate with screws is welded to the upper end of the side metal detector.

[0009] Preferably, a vertical hole is provided on the inner side of the top cover corresponding to the metal detector head on the side.

[0010] Preferably, the output end of the lifting cylinder is fixedly installed to the top cover by screws, and an assembly frame is welded onto the cylinder body of the lifting cylinder. The assembly frame and the support leg are fixedly installed by bolts.

[0011] Preferably, the top rotating detection assembly includes a rotating shaft, a connector integrally formed at one end of the rotating shaft and connected to a rotating motor, bearing seats mounted at both ends of the rotating shaft by key pins, a flange fixed to the bearing seats and to the top cover by screws, and a metal detection strip fixed on the rotating shaft by clamps.

[0012] Preferably, the conveying mechanism includes a support frame fixedly installed with the frame, a bearing plate fixedly installed with the support frame by bolts, rotating rollers located at both ends of the bearing plate and installed with the support frame, and a conveyor belt arranged around the bearing plate and driven by the rotating rollers.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The top rotating detection component uses a rotating motor to drive the metal detection strip to adjust at multiple angles, conforming to the undulating surface of the fabric in real time, improving the detection rate of deeply embedded metals. The side metal detection head is embedded in the vertical groove of the support foot, covering the blind areas on both sides of the conveyor belt. Combined with the vertical hole of the top cover to avoid obstruction, it achieves a "top to side" dual scan.

[0015] 2. The lifting cylinder drives the top cover to rise and fall as a whole, and is fixed to the support feet by mounting bracket bolts. It is compatible with continuous detection of single-layer to multi-layer fabrics, avoiding collisions with the top cover. The rotating probe maintains a floating gap with the fabric, and maintains sensitivity by adjusting the angle rather than by pressure contact, thus protecting the pile structure.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0022] Example

[0023] A metal detection device for producing simulated long-pile fabric, such as Figure 1-5 As shown, it includes a frame 1, a conveying mechanism 2 mounted on the frame 1, a drive motor 3 mounted on one side of the conveying mechanism 2, a metal detection mechanism 4 mounted on the frame 1 and installed in conjunction with the conveying mechanism 2, and a PLC control box 5 mounted below the frame 1 and connecting the drive motor 3 and the metal detection mechanism 4.

[0024] The conveying mechanism 2 includes a support frame 21 fixedly installed with the frame 1, a bearing plate 22 fixedly installed with the support frame 21 by bolts, rotating rollers 23 located at both ends of the bearing plate 22 and installed with the support frame 21, and a conveyor belt 24 arranged around the bearing plate 22 and driven by the rotating rollers 23.

[0025] Specifically, one of the rotating rollers 23 in the conveying mechanism 2 is connected to the output end of the drive motor 3. The drive motor 3 drives the rotating roller to drive the conveyor belt 24 to run, thereby conveying the simulated long-pile fabric layer that needs to be tested.

[0026] The metal detection mechanism 4 includes two identical support legs 41, a side metal detector head 42 embedded in the upper inner side of the support legs 41, a top cover 43 located above the two support legs 41 and supported by the support legs 41, a lifting cylinder 44 fixedly installed with the support legs 41 and the top cover 43, a rotary motor 45 fixedly installed on one side of the top cover 43, and a top rotating detection assembly 46 embedded in the lower end of the top cover 43 and connected to the output end of the rotary motor 45.

[0027] The support base 41 is located on both sides of the conveying mechanism 2 and is fixedly installed with the frame 1. A vertical groove 411 for embedding the side metal detector head 42 is provided on the upper inner side of the support foot 41.

[0028] The upper end of the side metal detector head 42 is welded with a horizontal plate 421 with screws. Specifically, when the side metal detector head 42 is inserted into the vertical groove 411, it abuts against the support foot 41 through the horizontal plate 421, and the screw is screwed into the support foot 41 for fixation.

[0029] A vertical hole 431 is provided on the inner side of the top cover 43 corresponding to the side metal detector 42. Specifically, the vertical hole 431 can prevent the top cover 43 from covering the side metal detector 42 and maintain the detection accuracy of the side metal detector 42.

[0030] The output end of the lifting cylinder 44 is fixedly installed to the top cover 43 by screws. An assembly frame 441 is welded onto the cylinder body of the lifting cylinder 44. The assembly frame 441 is fixedly installed to the support leg 41 by bolts. Specifically, when detecting the stacked simulated long-haired fabric layer, the height of the top cover 43 can be raised or lowered by the lifting cylinder 44 to prevent the top cover 43 from blocking the simulated long-haired fabric layer on the conveying mechanism 2.

[0031] The top rotating detection assembly 46 includes a rotating shaft 461, a connector 462 integrally formed at one end of the rotating shaft 461 and connected to a rotary motor 45, bearing seats 463 mounted at both ends of the rotating shaft 461 by key pins, a flange 464 fixed to the bearing seats 463 and to the top cover 43 by screws, and a metal detection strip 465 fixed to the rotating shaft 461 by clamps. Specifically, the angle of the metal detection strip 465 is adjusted by driving the rotating shaft 461 to rotate via the rotary motor 45, which allows the top rotating detection assembly 46 to flexibly adjust its angle, improving the flexibility and range of detection.

[0032] It should be further explained that the PLC control box 5 is specifically connected to the drive motor 3, the side metal detector 42, the rotary motor 45, and the metal detector strip 465 via wires. When the entire device is running, the drive motor 3 drives the conveyor belt 24 to transport the simulated long-haired fabric layer to be detected. The side metal detector 42 and the metal detector strip 465 simultaneously detect the simulated long-haired fabric layer being transported. At the same time, the rotary motor 45 drives the rotating shaft 461 to adjust the orientation angle of the metal detector strip 465 so that the metal detector strip 465 always faces the simulated long-haired fabric layer. When the side metal detector 42 and the metal detector strip 465 detect metal in the simulated long-haired fabric layer, they promptly send a signal to the PLC control box 5, thereby controlling the drive motor 3 to rotate and driving the conveyor belt 24 to reverse and remove the simulated long-haired fabric layer containing metal, making it convenient for the operator to remove.

[0033] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
