Detailed implementation manners

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0062] Embodiment 1

[0063] Please refer to Figures 1 - 15 , the present invention provides a technical solution: a packing line tray, including a tray 2 stacked on a base 1 for placing bobbin yarns 3 and a support mechanism 4 provided between two adjacent trays 2 for supporting the tray 2, further including: the support mechanism 4 includes: a second support assembly 42, including support rods 422 provided at the four corners of the tray 2 for supporting the tray 2, a connection unit 421 provided at the lower end of the support rod 422 for connecting the support rod 422 to the bottom tray 2, and a fixing unit 423 provided at the upper end of the support rod 422 for connecting the support rod 422 to the top tray 2; a third mounting hole 203 for mounting the connection unit 421 is provided at the upper end of the tray 2, and a fourth mounting hole 204 for mounting the fixing unit 423 is provided at the lower end of the tray 2.

[0064] It should be noted that during operation, when stacking the cheese bobbins 3, place the tray 2 on the base 1, and then evenly stack the cheese bobbins 3 on the tray 2. When a tray 2 is full, install the support mechanism 4 at the set positions at the four corners of the tray 2, insert the connection unit 421 into the third mounting hole 203. After the cheese bobbins 3 on one layer of the tray 2 are stacked, place another tray 2 on the fixing unit 423, align the fixing unit 423 with the fourth mounting hole 204, and then place the tray 2 on the fixing unit 423. At this time, the upper tray 2 presses the fixing unit 423 downward, causing the support rod 422 to drive the connection unit 421 to move inside the third mounting hole 203, and then snap and fix inside the third mounting hole 203 to complete the fixing work of the lower end of the second support assembly 42 on the first layer of the tray 2. Then, after the cheese bobbins 3 on the second layer of the tray 2 are stacked, install the second support assembly 42 on the second layer of the tray 2, insert the connection unit 421 into the third mounting hole 203 on the second layer of the tray 2, and during the insertion process, the connection unit 421 is connected to the fixing unit 423 on the first layer. When stacking the third layer of the tray 2, the third layer of the tray 2 presses the support rod 422 on the second layer downward, causing the connection unit 421 on the second layer to snap and fix in the fixing unit 423 on the first layer to complete the fixing work of the upper end of the second support assembly 42 on the first layer of the tray 2. By analogy, stack multiple layers of the tray 2. When the installation of the cheese bobbins 3 on the top layer is completed, fix the tray 2 on the fixing unit 423 on the top layer, and wind and fix the top layer of the tray 2 and the lower layer of the tray 2 with a plastic film. When the top layer of the tray 2 is fixed, evenly wind the entire perimeter of the tray 2 with the plastic film. The four corners between two adjacent trays 2 are fixedly connected by the second support assembly 42. This four-corner support method can evenly disperse the weight of the tray 2 and the cheese bobbins 3, greatly improving the stacking stability of the tray 2. Moreover, the two trays 2 are fixedly connected, making them more stable during transportation, effectively reducing the risk of shaking and tipping of the tray 2, ensuring the safety of the cheese bobbins 3, and reducing damage to the cheese bobbins 3 caused by shaking during transportation.

[0065] In one embodiment, the connection unit 421 includes: a frame inserted inside the third mounting hole 203; a pushing member disposed on the frame and connected to the support rod 422; a fixing member disposed inside the frame, with its top connected to the pushing member and its bottom connected to another fixing unit 423, and it expands inside the frame under the extrusion of the pushing member for fixedly connecting the support rod 422 to the fixing unit 423 and the tray 2 at its top.

[0066] With this design, refer to Figures 8 - 15, the connecting unit 421 is inserted into the third mounting hole 203 through the frame, providing basic positioning and support for the entire connecting structure. The pushing member is connected to the support rod 422. When the support rod 422 is affected by an external force or its own gravity, the pushing member can convert this force into a force acting on the fixing member. The fixing member makes an expansion movement inside the frame. Its top is connected to the pushing member, and its bottom is connected to another fixing unit 423. When the fixing member expands, it will closely fit with the relevant parts of the support rod 422, the fixing unit 423, and the tray 2, thereby improving the reliability of the connection. Even when subjected to a large external force impact or vibration, the connection stability can be maintained, ensuring that the packing line tray 2 does not have problems with loose structure during stacking and transportation.

[0067] In one embodiment, the frame includes: a top plate 4211 inserted inside the third mounting hole 203; a mounting frame 4212 provided at the lower end of the top plate 4211 and sleeved on the fixing member; and mounting brackets 42111 provided at equal angles at the lower end of the top plate 4211 for mounting the fixing member.

[0068] With this design, referring to Figure 13 , the top plate 4211 is inserted inside the third mounting hole 203. This design can achieve precise positioning of the frame and the tray 2. The third mounting hole 203 provides a clear installation position and guidance for the top plate 4211, ensuring that the frame can be accurately installed on the tray 2 during installation, avoiding problems such as loose connection or unstable structure caused by installation deviation. The mounting frame 4212 is provided at the lower end of the top plate 4211 and sleeved on the fixing member, providing a stable support and guiding structure for the fixing member. The mounting frame 4212 can limit the movement direction of the fixing member, enabling it to expand and contract only within a predetermined track, ensuring the stability and reliability of the movement of the fixing member. The mounting brackets 42111 are provided at equal angles at the lower end of the top plate 4211 for mounting the fixing member, further enhancing the overall stability of the frame. The multiple mounting brackets 42111 are evenly distributed, capable of evenly dispersing the force borne by the fixing member to the top plate 4211, avoiding structural deformation or damage caused by excessive local stress, thereby improving the load-bearing capacity and stability of the entire connecting unit 421.

[0069] In one embodiment, the pushing member includes: a connecting rod 42121 provided at the lower end of the support rod 422 and moving downward together with the support rod 422; a pushing rod 42122 provided at the lower end of the connecting rod 42121 and passing through the top plate 4211; a rotating rod 42123 provided at the lower end of the pushing rod 42122 and connected to the fixing member for pushing the fixing member to move; and a through slot 421101 is formed on the top plate 4211 for the pushing rod 42122 to move.

[0070] With this design, referring to Figure 13 andFigure 14 The connecting rod 42121 is set at the lower end of the support rod 422 and moves downward with the support rod 422. When the gravity of the support rod 422 when the tray 2 is stacked moves downward, the connecting rod 42121 moves downward synchronously, and transmits the force to the pushing rod 42122, and the pushing rod 42122 transmits the force to the rotating rod 42123, and finally acts on the fixing part to realize the expansion movement of the fixing part. The entire force transmission process is smooth and continuous, which reduces energy loss and improves transmission efficiency, ensuring that the movement of the support rod 422 can be accurately converted into the fixing action of the fixing part. The through groove 421101 opened on the top plate 4211 enhances the stability of the movement of the pushing rod 42122, so that it can only move up and down within the range of the through groove 421101, avoiding the pushing rod 42122 from deflecting or shaking during the movement, thereby ensuring the stability and reliability of the entire pushing part structure.

[0071] In one embodiment, the fixing member includes: a fixing claw 42124, which is arranged at the lower end of the rotating rod 42123 and flipped outward as the pushing rod 42122 moves downward; a stabilizing rod 42125, which is arranged at the upper end of the fixing claw 42124 and connected to the mounting frame 42111; and a movable groove 42101 for the fixing claw 42124 to move is opened on the mounting frame 4212.

[0072] This design, see Figures 11 - 14 The fixing claw 42124 is arranged at the lower end of the rotating rod 42123, and is turned outwardly as the pushing rod 42122 moves downward. This design enables the fixing claw 42124 to expand outwardly quickly when the pushing member is moved by the downward force of the support rod 422, and then be clamped and fixed in the fixing unit 423 and the fourth mounting hole 204. The fixing claw 42124 fits tightly with the relevant parts of the support rod 422 and the fixing unit 423 to form a reliable clamping force. This clamping and fixing method can effectively prevent the support rod 422 from being clamped during use. To prevent looseness or shaking, ensure that the connection between the support rod 422 and the fixing unit 423 on its top and the pallet 2 is stable, thereby improving the stacking stability of the baling line pallet 2. A moving groove 42101 for the movement of the fixing claw 42124 is provided on the mounting frame 4212, providing sufficient space and a smooth track for the expansion movement of the fixing claw 42124. When the fixing claw 42124 is flipped outward, it can slide along the moving groove 42101, reducing the movement resistance, so that the fixing claw 42124 can complete the expansion action quickly and accurately.

[0073] In one embodiment, the pusher further includes: an elastic member 42126 disposed between the connecting rod 42121 and the mounting frame 4212; a protective ring 42112 is provided at the lower end of the top plate 4211 for protecting the elastic member 42126; a through hole 421102 for the movement of the elastic member 42126 is formed on the top plate 4211, and the elastic member 42126 is made of a damped spring or an elastic pad.

[0074] With such a design, referring to Figure 13 and Figure 14 , the elastic member 42126 is disposed between the connecting rod 42121 and the mounting frame 4212. When the support rod 422 drives the connecting rod 42121 to move downward, the elastic member 42126 will be compressed. When it is necessary to disassemble the entire cheese 3 at the designated location, the topmost tray 2 is removed, and then the downward force of the support rod 422 disappears. The elastic member 42126 will automatically expand by virtue of its elastic restoring force, pushing the connecting rod 42121 upward, and then driving the push rod 42122 and the rotating rod 42123 to move, causing the fixing member to contract, releasing the restriction of the fixing member on the tray 2 and the fixing unit 423, and then holding the support rod 422 to take out the connecting unit 421 from the inside of the third mounting hole 203. This automatic reset function enables the fixing member to flexibly adjust its state under different working conditions. When it is necessary to release the connection, without additional operation, the elastic member 42126 can push each component back to the initial position, improving the convenience and efficiency of the operation.

[0075] In one embodiment, the fixing unit 423 includes: a fixing ring 4231 disposed at the upper end of the support rod 422 and inserted into the inside of the fourth mounting hole 204; a limiting strip 4232 disposed at the upper end of the fixing ring 4231; a limiting groove 423101 is equally angularly formed on the side of the fixing ring 4231; the fixing claw 42124 is inserted and fixed inside the limiting groove 423101.

[0076] With such a design, referring to Figures 10 - 12 , the fixing ring 4231 is disposed at the upper end of the support rod 422 and inserted into the inside of the fourth mounting hole 204. This design can achieve the precise positioning of the fixing unit 423 and the tray 2. The fourth mounting hole 204 provides a clear installation position and guidance for the fixing ring 4231, ensuring that the fixing unit 423 can be accurately installed on the tray 2 during the installation process, avoiding problems such as loose connection or unstable structure caused by installation deviation. At the same time, when the fixing claw 42124 expands outward, it passes through the limiting groove 423101 on the fixing ring 4231, and the limiting strip 4232 can restrict the fixing claw 42124, preventing the fixing ring 4231 from falling off from the inside of the fourth mounting hole 204, improving the accuracy and reliability of the entire connection structure.

[0077] In one embodiment, a fixing groove 205 communicating with the fourth mounting hole 204 is formed in the tray 2 for restricting the fixing claw 42124.

[0078] With such a design, referring to Figure 10 , the fixing groove 205 communicates with the fourth mounting hole 204. When the fixing claw 42124 is inserted and fixed inside the limiting groove 423101 of the fixing ring 4231 and expands outward under the action of the pushing member, it can be clamped and fixed inside the fixing groove 205, ensuring that the fixing claw 42124 can fix the fixing ring 4231 and the tray 2, enabling fixed connection between two adjacent trays 2, ensuring that the fixing claw 42124 always maintains an effective clamping force with the support rod 422 and the fixing unit 423, thereby improving the connection stability between the support rod 422 and the tray 2.

[0079] Embodiment Two

[0080] In one embodiment, the support mechanism 4 further includes a first support component 41 inserted between the third mounting hole 203 and the fourth mounting hole 204.

[0081] With such a design, referring to Figure 5 , the first support component 41 is made of a steel pipe or a plastic pipe and is inserted between the third mounting hole 203 and the fourth mounting hole 204, providing additional support force for the tray 2. When the packaging line trays 2 are stacked, the gravity of the upper tray 2 will be transmitted to the lower tray 2 through the first support component 41. The first support component 41 can share the gravity of the tray 2, thereby enhancing the stability of the entire tray 2 structure and preventing the tray 2 from being supported by the bobbin 3 and tilting.

[0082] In one embodiment, a first mounting hole 201 for mounting the coil roller 31 on the bobbin 3 is formed at the upper end of the tray 2; a second mounting hole 202 for mounting the coil roller 31 on the bobbin 3 is formed at the upper end of the tray 2; the first mounting hole 201 and the second mounting hole 202 are arranged staggeredly and have different hole diameters.

[0083] With such a design, referring to Figure 5 and Figure 6 , since the bobbin 3 is generally frustum-shaped and has different diameter sizes at the top and bottom, when the bobbin 3 is installed on the tray 2, it is installed alternately up and down. In this way, more bobbins 3 can be accommodated on the tray 2 and the bobbins 3 can be placed more stably. By setting mounting holes with different sizes, it is convenient to distinguish the front and back sides of the bobbin 3 installation. This staggered arrangement can make more full use of the space at the upper end of the tray 2, install more bobbins 3 within a limited area, and make the spacing between the bobbins 3 more reasonable by reasonably arranging the position and spacing of the mounting holes, which not only ensures the stability of the bobbins 3 but also improves the loading capacity of the tray 2 and reduces the transportation cost.

[0084] In addition, if the description involves "first", "second", etc. in the embodiments, such descriptions of "first", "second", etc. are for descriptive purposes only and should not be construed as indicating or implying their relative importance to the specification or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature.
