Description

Technical Field

[0001] The utility model relates to leather processing equipment, in particular to a needle detector. Background Art

[0002] A needle detector, also called a needle inspection machine, is a ferromagnetic metal induction instrument, which is a detection instrument applied to the textile and leather industries under the classification of metal detectors. It is mainly used for detecting ferromagnetic metal foreign objects in leather and textiles. Therefore, the main purpose of developing the metal detection instrument is to detect broken needles in leather textiles.

[0003] The existing needle detector includes a frame, a conveyor belt arranged on the frame, and a detection table fixedly arranged on the frame and located above the conveyor belt. A transmission gap is formed between the conveyor belt and the detection table. The participation rate of the needle detector in the entire production process is only in the detection step before leaving the factory, resulting in a low usage frequency of the needle detector. Since the needle detector has two functions of conveying and detecting, and the product needs to be conveyed in each step of the entire production process, the utilization rate of the conveyor belt is extremely high. If the conveying function of the needle detector can be utilized on the premise that the detection function is not working, the production cost of the product can be reduced to a certain extent and the working efficiency of the equipment can be maximized. However, due to the existing detection table that limits the transmission height of the needle detector, the types of conveyed products are greatly limited, thus affecting its practicality in the actual use process. Based on the above problems, this improvement came into being. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a needle detector which can maximize the transmission function benefit on the premise of taking into account the detection function, so as to reduce the production cost and improve the equipment utilization rate.

[0005] The above technical purpose of the utility model is achieved by the following technical solutions: a needle detector includes a frame, a conveyor belt arranged on the frame, and a detection table arranged on the frame. A receiving cavity is formed below the conveyor belt on the frame. The detection table is movably arranged on the frame through a movable component, so that the detection table has a detection position above the conveyor belt and a receiving position in the receiving cavity. When the detection table is in the detection position, it is fixed to the frame through a detachable upper fixing component. When the detection table is in the receiving position, it is fixed to the receiving cavity through a detachable lower fixing component.

[0006] By adopting the above technical solution, when the conveying function of the needle detector is to be used alone, the upper fixing component is disassembled, and then the detection table is rotated into the storage cavity located below the machine frame through the movable component, and the lower fixing component is provided to fix the detection table in the storage cavity. Without the obstruction of the detection table, products of any size can be conveyed on the conveyor belt, and the detection table located in the storage cavity will not occupy extra factory space. Through the above structure, the needle detector can maximize the conveying function benefit on the premise of taking into account the detection function, so as to reduce the production cost and improve the equipment utilization rate.

[0007] It is further set that: the movable component includes a first reversing structure for converting the detection table in the detection position to one side of the machine frame and a second reversing structure for converting the detection table in the position on one side of the machine frame into the storage cavity.

[0008] By adopting the above technical solution, the position and direction of the detection table are changed through the cooperation of the first reversing structure and the second reversing structure, so as to realize the switching of the detection table between the two positions above and below the conveyor belt and meet the position conversion requirements.

[0009] It is further set that: the first reversing structure includes a first turning seat and a connecting seat connecting one end of the detection table and rotatably connected to the first turning seat, and the first reversing structure rotates in the vertical direction.

[0010] By adopting the above technical solution, the connecting seat and the first turning seat are rotatably matched to rotate the detection table from above the conveyor belt to the outside of the machine frame to realize the rotational switching in the vertical direction.

[0011] It is further set that: the second reversing structure is a second turning seat fixedly arranged at the bottom of the machine frame and rotatably connected to the first turning seat, and the second reversing structure rotates in the horizontal direction.

[0012] By adopting the above technical solution, the second turning seat realizes the horizontal rotation of the detection table and enters the storage cavity.

[0013] It is further set that: the upper fixing component includes a fixing bolt threadedly connected to the detection table and a fixing screw hole opened on the machine frame for the fixing bolt to enter.

[0014] By adopting the above technical solution, the fixing bolt is threadedly connected to the detection table to drive the fixing bolt into the fixing screw hole, so as to realize the detachable fixed installation between the detection table and the machine frame. This method has a simple structure and low cost.

[0015] It is further set that: the lower fixing component is a fixing frame fixedly arranged at the bottom of the machine frame and a fixing groove formed in the fixing frame and having an opening for the detection table to enter and exit, and the opening of the fixing groove is horizontally oriented.

[0016] By adopting the above technical solution, the inspection table rotates horizontally and enters the fixed groove through the opening, so that the free end of the inspection table opposite to the movable component can be supported and fixed in the fixed groove, thereby realizing the stable fixation of the inspection table in the storage cavity.

[0017] It is further set that when the inspection table is located in the fixed groove, the fixing bolt is located in the fixed groove and cooperates with the fixed groove to drive the inspection table to move vertically upward.

[0018] By adopting the above technical solution, when the inspection table is located in the fixed groove, the fixing bolt is also located in the fixed groove. At this time, by rotating the fixing bolt in the reverse direction so that the fixing bolt abuts against the bottom of the fixed groove, an upward supporting force can be formed on the inspection table through the fixing bolt, so as to better support and fix the inspection table and avoid deformation caused by long-term stress at the connection position.

[0019] It is further set that when the inspection table rotates to one side of the frame through the first commutation structure, a support block for supporting the inspection table to maintain this state is formed on the first commutation structure.

[0020] By adopting the above technical solution, the setting of the support block effectively supports the inspection table in this state, facilitating the switching operation of the inspection table.

[0021] In summary, the utility model has the following beneficial effects: on the premise of taking into account the detection function, the utility model can maximize the transmission function benefit, thereby reducing production costs and improving equipment utilization rate.
