Description

Technical Field

[0001] The utility model relates to the technical field of electron accelerator irradiation processing, in particular to an insulating tray for accelerator irradiated conductive products. Background Art

[0002] When irradiating conductive outer packaging products (aluminum foil + nylon) with an electron accelerator, the beta rays are charged and the tray is made of stainless steel, which causes current accumulation in the product outer packaging and converges into one point, resulting in electrical breakdown. If metal conductive equipment is used as a conductor to connect the product outer packaging and the stainless steel tray during the irradiation process, the beta rays will not be able to fully act on the product, and will be guided out through the metal equipment in advance, which will reduce the absorbed dose of the product.

[0003] In addition, existing irradiation pallets are all single-layer pallets, that is, the materials are placed directly on the pallets and then irradiated. However, for some low-density products, if single-layer pallets are used, in order to ensure irradiation efficiency, the product packaging volume or the height of the irradiation stacking needs to be increased, but this is prone to accidents such as tipping over during actual processing. Utility Model Content

[0004] The purpose of the utility model is to provide an insulating tray for accelerator irradiation of conductive products, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an insulating tray for accelerator irradiation of conductive products, comprising a tray; a protective frame detachably arranged inside the tray, with its two ends elastically connected to connectors in connecting holes at the outer edge endpoints of the top and bottom of the tray and fixings symmetrically arranged inside the two ends of the connectors, wherein the connector also includes an outer tube, a connecting column elastically connected to the inner bottom plane of the outer tube and slidingly connected to the inner wall of the outer tube.

[0006] Preferably, the tray further includes lifting grooves symmetrically arranged on both sides.

[0007] Preferably, through holes are provided at both ends of the protective frame and an even number of foot pads are symmetrically provided at the bottom.

[0008] Preferably, the fixing member includes a sleeve; a telescopic rod located inside the sleeve; and a first spring disposed inside the sleeve and movably sleeved with an outer wall of the telescopic rod.

[0009] Preferably, two or more sliding grooves are evenly arranged around the inner wall of the outer cylinder.

[0010] Preferably, the outer wall of the connecting column is surrounded by a sliding key that matches the number and size of the sliding grooves, and the bottom of the connecting column is fixedly connected to a second spring, and the other end of the second spring is connected to the inner bottom plane of the outer cylinder.

[0011] Preferably, the outer arc surface of the connecting column is provided with symmetrically distributed inner grooves adapted to the telescopic movement of the fixing member, and the interior of the connecting hole is provided with symmetrically distributed card slots, which are engaged with the top of the telescopic rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The insulating pallet of the utility model completely isolates the product to be processed from the stainless steel pallet by adding a protective frame made of insulating material (PVC) between the product and the pallet, so that the product cannot accumulate current and cause electrical breakdown, and will not interfere with the effect of beta rays on the product.

[0014] 2. The insulating pallet of the present invention can be combined into any number of pallets by splicing them up and down, thereby effectively solving the irradiation problem of low-density and small-packaged products and improving the irradiation efficiency. The gap in the middle is conducive to heat dissipation during irradiation, further improving the safety of the product during irradiation, and can absorb the interference force received by the pallet during transportation through the spring force set in the connecting piece, thereby improving the stability of the pallet.

[0025] See also Figure 1-7 The utility model provides a technical solution: an insulating tray for accelerator irradiation of conductive products, comprising a tray 1; a protective frame 2 detachably arranged inside the tray 1, with its two ends elastically connected to connectors 4 in connecting holes 3 at the outer edge endpoints of the top and bottom of the tray 1, and fixing members 5 symmetrically arranged inside the two ends of the connector 4, wherein the connector 4 also includes an outer tube 410, a connecting column 420 elastically connected to the inner bottom plane of the outer tube 410 and slidingly connected to the inner wall of the outer tube 410.

[0026] In this embodiment, the protective frame 2 is placed inside the pallet 1 and the outer edge of the protective frame 2 is engaged with the inner wall of the pallet 1 to maintain stability during operation and prevent displacement inside the pallet 1. It is further separated by a certain distance from the inner bottom plane of the protective frame 2 by an even number of foot pads 6 symmetrically arranged at the bottom. At the same time, the protective frame 2 is made of insulating PVC to prevent the product from accumulating current and causing electrical breakdown, and will not interfere with the effect of beta rays on the product. When installation or disassembly is required, the protective frame 2 is pressed into the interior of the pallet 1 or taken out of the pallet 1 through the through holes 7 arranged at both ends. The pallet 1 also includes lifting grooves 8 symmetrically arranged on both sides. The provision of the lifting grooves 8 facilitates the movement and transportation of the entire pallet 1.

[0027] In this embodiment, a through connection hole 3 is provided at the outer edge end points of the top and bottom of the tray 1. The connector 4 is connected to the connection hole 3 at the bottom of the tray 1 on the upper layer and the connection hole 3 at the top of the tray 1 on the lower layer respectively through the fixing members 5 located inside the two ends in the vertical direction. The connector 4 also includes an outer cylinder 410 with two or more sliding grooves evenly arranged around the inner wall and a connecting column 420 elastically connected to the inner bottom plane of the outer cylinder 410 through a second spring 9, wherein one end of the second spring 9 is fixedly connected to the bottom of the connecting column 420 and the other end is fixedly connected to the inner bottom plane of the outer cylinder 410. When in use, first plug the outer cylinder 410 at the bottom of the connector 4 into the outer cylinder 410. Inside each connecting hole 3 at the top of the tray 1, another tray 1 is then placed vertically on the upper end of the tray 1 on the lower layer through the pulling groove 8 and aligned so that the top connecting column 420 of the connector 4 is inserted into each connecting hole 3 at the bottom of the tray 1 on the upper layer. In this way, the connecting holes 3 at the bottom of the upper tray 1 are respectively plugged and fixed to the top connecting columns 420 of the vertically adjacent connectors 4. By splicing up and down, any number of trays 1 can be combined, which can effectively solve the irradiation problem of low-density and small-packaged products and improve the irradiation efficiency. The gap in the middle is conducive to heat dissipation during irradiation, further improving the safety of the product during irradiation.

[0028] In this embodiment, by arranging a sliding key 421 around the outer wall of the connecting column 420 that matches the number and size of the sliding grooves on the inner wall of the outer cylinder 410, when pressure is applied to the upper tray 1, the second spring 9 in the lower connecting member 4 will elastically contract, and the elastic contraction or reset of the second spring 9 will also drive the connecting column 420 to slide up and down along the sliding grooves arranged in the vertical direction inside the outer cylinder 410 through the sliding key 421. The relative sliding between the sliding key 421 and the sliding groove will generate friction damping to absorb the interference force received by the pallet 1 during transportation, thereby improving the stability of the pallet 1.

[0029] In this embodiment, the fixing member 5 includes a sleeve 510; a telescopic rod 530 elastically connected to the inside of the sleeve 510 through a first spring 520; one end of the first spring 520 is fixedly connected to the bottom end of the sleeve 510 and the other end is movably sleeved on the outer wall of the telescopic rod 530, wherein the fixing member 5 is threadedly connected to both sides of the top inner side of the connecting column 420 through the end of the sleeve 510. When the fixing member 5 is installed, it is inserted into the connecting hole 3 along with the connecting column 420 at the top of the connecting member 4. When the connecting column 420 moves into the connecting hole 3, the fixing member 5 is inserted into the connecting hole 3 along with the connecting column 420. During the process, the outer edge of the connecting hole 3 applies pressure to the top of the telescopic rod 530, causing the telescopic rod 530 to squeeze the first spring 520 and retract into the sleeve 510. When the connecting column 420 continues to move downward to the slot 11 vertically adjacent to the top of the telescopic rod 530, the first spring 520 is reset. The compression elastic force of the first spring 520 resets the telescopic rod 530 to extend from the inside of the sleeve 510, so that the top of the telescopic rod 530 is engaged with the slot 10, thereby fixing the connecting piece 4 to the upper tray 1.
