Abstract
Description
Technical Field
[0001] The invention relates to the field of fuse packaging, in particular to a packaging tray for limiting the position of a fuse shell and a contact knife. Background Art
[0002] In fuse packaging, in order to avoid fuse bumps, there are various packaging trays of various specifications. For fuse packaging with a contact knife, the fuse is generally packaged and fixed by fixing the shell limit groove and the contact knife limit groove on the tray. For example, the fuse packaging tray disclosed in Chinese patent 2018221683331 uses the shell limit groove and the contact knife limit groove to package and fix the fuse, and the tray is integrally formed with the shell limit groove and the contact knife limit groove. This type of packaging pallet can effectively achieve fixed packaging of fuses and avoid bumps. It has obvious advantages when the product is of a single specification and large quantity. However, it has certain limitations when the product quantity is small. The reason is that in this type of pallet, the shell limit groove, the contact knife limit groove and the pallet are fixed structures, and their structural form is fixed. The same pallet may be limited to only one specification of fuse packaging, or, when designing the pallet, several shell limit grooves and contact knife limit grooves with different shell and contact knife specifications are designed on it, so that one pallet can hold fuses of multiple specifications. For example, the tray structure disclosed in the above patent can hold fuses of three specifications. However, when there are only a few fuses of one specification and model, and the number of other fuses is relatively large, for example, 3 fuse products of the same shell size and different contact blade specifications can be placed in the same pallet, each with 5 pieces. However, in reality, there are 3 fuse products with one specification of contact blade, 4 fuse products with one specification of contact blade, and 8 fuse products with another specification of contact blade. In this case, at least 2 pallets are needed. When only one specification and size of fuse can be placed in the pallet, at least 3 pallets are needed. Moreover, when there is no contact blade limit groove structure corresponding to the specification of the fuse product to be packaged in the pallet, it cannot be packaged. This causes waste in packaging and increases packaging costs. Especially when the quantity is small, the packaging cost may account for a large proportion of the various costs of the product, resulting in a lot of packaging waste. In addition, since the existing pallet structure is an integrated structure, different pallet structures need to be processed with different molds. When the product quantity is small, the mold opening cost is very high, accounting for a very high proportion of the packaging cost. Summary of the invention
[0003] The object of the present invention is to provide a combinable tray for packaging fuses, which can select the shell limit groove structure and the contact knife limit groove structure specifications according to the fuse specifications, so that the tray can be selected according to the fuse specifications actually required to be packaged, adapt to the packaging of various fuse specifications, and reduce packaging costs.

[0020] A combinable tray for fuse packaging of the present invention comprises a tray body, at least one shell limiting groove structure, and at least two knife contact limiting groove structures; a receiving groove with a horizontal bottom is provided on the tray body, and the shell limiting groove structure is arranged in the receiving groove of the tray body in a detachable manner, an adhesive manner or an integrally formed manner; the shell limiting groove structure comprises a plurality of shell limiting grooves arranged side by side at intervals, and the knife contact limiting groove structure comprises a plurality of knife contact limiting grooves arranged side by side at intervals; the knife contact limiting groove structure is arranged on the receiving groove at intervals in a detachable manner or an adhesive manner; a knife contact limiting groove structure is respectively arranged on both sides of each shell limiting groove structure, and the shell limiting groove and the knife contact limiting groove are arranged correspondingly.
[0021] With respect to the above technical solution, preferred embodiments are now cited and specifically described in conjunction with drawings.
[0022] The combinable tray of the present invention is shown in FIG. Figure 1 and Figure 5 , including a tray body 10, a shell limiting groove structure 20, and a knife contact limiting groove structure 30. Among them, the tray body 10, see Figure 2 , which is processed by vacuum forming or injection molding process, has a receiving groove 11, and the bottom of the receiving groove is a horizontally arranged plane structure for placing the shell limiting groove structure 20 and the contact knife limiting groove structure 30.
[0023] The housing limit groove structure 20, see 3, is a strip structure, and its bottom matches the bottom of the receiving groove 11 of the tray body 10. Along the length direction of the housing limit groove structure, a plurality of housing limit grooves 21 are arranged side by side and spaced apart. The housing limit grooves 21 are U-shaped. The shape of the housing limit grooves 21 is sufficient to accommodate the fuse housing, and the two ends of the fuse housing are located on the two outer sides of the housing limit grooves 21.
[0024] The shell limit groove structure 20 can be an integrally formed structure, or a spliced structure formed by at least two groups of shell limit groove units spliced side by side. The shell limit groove unit includes at least one shell limit groove 21, and the specifications and models of the shell limit grooves 21 in a group of shell limit groove units are the same. When two groups of shell limit units are spliced, they can be spliced by the mortise and tenon structure set at both ends of the shell limit units, or spliced by gluing. When the mortise and tenon structure is used for splicing, the side surface of the shell limit unit located at the side of the accommodating groove of the tray body is a mortise-shaped structure.
[0025] When integrally formed, the specifications and models of the shell limit grooves of a shell limit groove structure 20 are completely the same. When spliced, the specifications and sizes of the shell limit grooves of each group of shell limit groove units can be the same or different. If they are the same, they are suitable for products with the same specifications of fuse shells, and if they are different, they are suitable for products with different specifications of fuse shells.
[0026] The shell limiting groove structure 20 can be set in the receiving groove of the tray body 10 by gluing. Alternatively, the shell limiting groove structure 20 is interference fit with the inner wall of the receiving groove of the tray body. In order to facilitate fixation, arrays of limiting grooves (not shown) can be set at intervals on the inner walls of the receiving groove of the tray body on opposite sides, and the two ends of the shell limiting groove structure 20 can be placed in the limiting grooves of the tray body to position the shell limiting groove structure 20.
[0027] When the fuse product shell specifications are few and the product volume is large, refer to Figure 6 In the receiving groove 11 of the tray body 10, a plurality of shell limiting groove structures 20 are integrally formed at intervals. When packaging, it is only necessary to place a matching contact knife limiting groove structure 30 in the receiving groove of the tray body 10 according to the specifications and dimensions of the fuse product. This structure can reduce the packaging tray assembly time and product packaging time during packaging.
[0028] When the fuse product shell has many specifications and small quantity, the shell limit groove structure 20 needs to be made separately. It can be directly made into a whole shell limit groove structure 20 according to needs, or made into shell limit groove units of various specifications for splicing. When made separately, it is processed by die cutting process.
[0029] When the outer diameter of the shell of the fuse products is the same, the length and the contact blade structure are different, the specification and structure of the shell limit groove structure 20 are the same. When the product volume is large, the shell limit groove structure 20 is integrally formed with the tray body. Figure 6 When the product quantity is small, the housing limiting groove structure 20 is formed separately.
[0030] The knife contact limit groove structure 30, see Figure 4 , in a strip-like structure, the bottom of which matches the bottom of the receiving groove 11 of the tray body 10. Along the length direction of the contact knife limiting groove structure, a plurality of contact knife limiting grooves 31 are arranged side by side and spaced apart. The contact knife limiting groove 31 is in the shape of a sofa-like structure, on which the contact knife of the fuse can be placed, and the contact knife is supported and protected from the bottom and left and right.
[0031] The knife contact limit groove structure 30 is an independent structure formed in one piece, or it can be formed by splicing at least two sets of knife contact limit groove units. The knife contact limit groove unit includes at least one knife contact limit groove. The splicing method is the same as the splicing method of the shell limit groove unit, and can be spliced by a similar mortise and tenon structure, or spliced by gluing.
[0032] When the contact blade limit slot structure 30 is an independent structure formed in one piece, the specifications and models of the contact blade limit slot are the same; when it is a spliced structure, the specifications and models of the contact blade limit slot can be the same or different. When the shell specifications of the fuse products are the same, but the contact blade specifications are different, refer to Figure 1 and Figure 5 , which can be solved by adjusting the structure and height of the knife contact limiting groove structure 30.
[0033] The knife contact limit groove structure 20 is an independent component, which is processed by die cutting. The knife contact limit groove structure 30 can be set in the receiving groove of the tray body 10 by gluing. It can also be realized by interference fit between the knife contact limit groove structure 30 and the inner wall of the receiving groove of the tray body. In order to facilitate fixation, array limit grooves (not shown) can be set at intervals on the inner walls of the opposite sides of the receiving groove of the tray body, and the two ends of the knife contact limit groove structure 30 can be placed in the limit groove of the tray body to position the knife contact limit groove structure 30.
[0034] The shell limiting groove structure 20 and the contact knife limiting groove structure 30 are made of EVA, EPE, EPP and other materials and are formed by die cutting.
[0035] The tray body 10, the shell limiting groove structure 20, and the contact knife limiting groove structure 30 are assembled and spliced according to the packaging requirements of the fuse product specifications and dimensions, such as Figure 1 and Figure 5 In the embodiment, the knife contact limiting groove structure 30 has different specifications and sizes, and can adapt to different knife contact heights.
[0036] When assembling the packaging tray, one shell limiting groove of the shell limiting groove structure 20 should generally correspond to the two contact knife limiting grooves on both sides thereof, so that each contact knife at both ends of the fuse product has a contact knife limiting groove to support and protect it.
[0037] The combinable tray of the present invention is Figure 1 Take the combination as an example: first select the shell limit groove structure 20 according to the shell specifications of the fuse product, select the corresponding touch knife limit groove structure 30 according to the touch knife specifications, determine the spacing between the shell limit groove structure 20 and the touch knife limit groove structure 30 according to the length of the fuse product, the length of the touch knife, etc., and according to the combination principle of setting a touch knife limit groove on both sides of a shell limit groove, respectively, put the shell limit groove structure 20 and the touch knife limit groove structure 30 on both sides into the accommodating groove of the tray body 10, and the two touch knife limit groove structures 30 between two adjacent shell limit groove structures 20 can be back-to-back arranged to improve the packaging stability and impact resistance. Manually adjust the spacing between the shell limit groove structure 20 and the touch knife limit groove structure 30 on both sides. When splicing is required, splice the shell limit groove structure 20 and the touch knife limit groove structure 30 in advance and then combine them with the tray body.
[0038] The packaging pallet of the present invention, through the combination of the shell limiting groove structure 20 and the contact knife limiting groove structure 30, and the unit splicing of the shell limiting groove structure 20 and the contact knife limiting groove structure 30, can be suitable for the packaging of various fuse specifications. In one packaging pallet, the packaging of fuse products of various specifications can be achieved, thereby improving the packaging efficiency and the utilization rate of packaging materials, improving the warehousing efficiency and transportation efficiency, and reducing the packaging, warehousing and transportation costs.
