Description

Technical Field

[0001] This utility model relates to the field of cold storage panel processing technology, and in particular to a cold storage panel interlayer filling material rod. Background Technology

[0002] In the production process of cold storage panels, the filling and distribution of interlayer materials are key aspects affecting product quality. Cold storage panels are typically composed of a core material (such as polyurethane or polystyrene) and a surface material. The interlayer bonding strength and the uniformity of the core material density directly determine the insulation performance, structural stability, and service life of the cold storage panel.

[0003] The existing method of filling the interlayer of cold storage panels involves inserting a filling gun into pre-drilled holes on the side of the mating cold storage panels. Workers inject foam material using the filling gun, and the material spreads and fills the gaps between the panels by its own expansion force. This method has defects. If there are irregular structures (such as concave or convex, or corners) in the gaps between the panels, the material is prone to accumulate locally. In narrow or hidden areas, the filling may be insufficient, resulting in voids and gaps.

[0004] From a practical production perspective, the characteristics of the core material impose stringent requirements on the filling and fabrication processes. Taking polyurethane as an example, it undergoes a rapid foaming reaction after filling. Uneven fabrication and excessive localized foaming pressure can lead to bulging and deformation of the surface material, while insufficient foaming can result in voids. These defects can easily become thermal bridges during long-term use in low-temperature cold storage, increasing energy consumption. For granular core materials such as polystyrene, if the distribution is uneven or the board density is inconsistent, chipping and corner breakage can easily occur during subsequent cutting and processing. Therefore, it is necessary to design a fabrication rod for interlayer filling of cold storage panels.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-4 As shown in the figure, the present invention provides a cold storage panel interlayer filling material rod, including a material rod assembly 1. The material rod assembly 1 is composed of an upper rod part 11 and a lower rod part 21 arranged opposite to each other. A fixing hole 12 is provided through the upper rod part 11, and a fixing hole 27 corresponding to the position of the fixing hole 12 is provided on the side of the lower rod part 21 that is in contact with the upper rod part 11. The upper rod part 11 is threadedly connected to the fixing hole 27 through the fixing hole 12 by a fastener, so as to realize the connection and fixation of the upper rod part 11 and the lower rod part 21.

[0028] Meanwhile, the upper rod 11 and the lower rod 21 are provided with connecting parts. Taking the upper rod 11 as an example, the connecting part includes a semi-circular connecting hole 16 on one side of the upper rod 11. The top of the connecting hole 16 extends inward to form a step 161 and the bottom extends to form a step 262. The lower rod 21 has a semi-circular connecting hole 25 on one side. The connecting hole 25 and the connecting hole 16 are spliced ​​together to form a circular channel to adapt to the pipeline connection of the external feeding equipment. The top of the connecting hole 25 extends inward to form a step 351, which corresponds to the position of step 161, and the bottom extends to form a step 452, which corresponds to the position of step 262. Through the adaptation of the hole position and the step, an installation foundation is provided for the pipeline connection.

[0029] With the help of the above-mentioned connection structure, when the external supply pipeline is connected to the circular channel formed by connecting hole 16 and connecting hole 25, step 161 and step 3251, and step 262 and step 4252 can limit the pipeline and prevent the pipeline from being over-inserted or offset. At the same time, the step structure can cooperate with the sealing parts (such as sealing rings) of the pipeline interface to fill the gaps and achieve a seal, effectively preventing material leakage during the supply process and ensuring the stability of the supply connection.

[0030] Meanwhile, a storage section is provided on the side of the upper rod 11 and the lower rod 21 that are close to each other. Specifically, the storage section has a connecting port 163 at the connecting hole 16. The connecting port 163 has a conical structure to facilitate material flow. The lower rod 21 has a corresponding conical connecting port 253 at the connecting hole 25, which is adapted to connect with the connecting port 163. The upper rod 11 has a material trough 13 parallel to the upper rod 11 at the connecting port 163. The material trough 13 has a hollow semi-cylindrical structure. The lower rod 21 has a material trough 22 parallel to the lower rod 21 at the connecting port 253. The material trough 22 has a similar semi-cylindrical structure. The material trough 13 and the material trough 22 are spliced ​​together to form a hollow columnar structure for temporary storage of foamed material.

[0031] With the help of the storage section structure, when the external feeding equipment conveys the foaming material through the circular channel formed by connecting hole 16 and connecting hole 25, the conical connecting port 163 and connecting port 253 can guide the material to flow smoothly into the material trough 13 and material trough 22. Since material trough 13 is a hollow semi-cylinder and material trough 22 is a similar semi-cylinder structure, the hollow columnar structure formed by the two can provide temporary storage space for the foaming material, which can buffer the feeding pressure and temporarily store the material to be diffused.

[0032] Furthermore, the upper rod 11 and the lower rod 21 are provided with a discharge section on their opposite sides. The discharge section includes a semi-conical groove 14 connected to both ends of the material trough 13. The groove 14 is connected to an inclined groove 15. The two ends of the material trough 22 are provided with a semi-conical groove 23. The groove 23 is connected to an open groove 24. The open groove 24 is connected to the rounded corners 26 at both ends of the lower rod 21. The inclined groove 15 and the open groove 24 are precisely fitted to form a channel 1 extending to both sides. The material trough 22 is also connected to multiple sets of equidistantly distributed injection holes 28 as a downward channel 2.

[0033] In actual use (refer to) Figure 2 In the configuration, the upper rod 11 is located at the upper end, the lower rod 21 is located at the lower end, the injection hole 28 faces downwards and is directly opposite the bottom area between the cold storage panels, and the two side channels open to the left and right corresponding to the edge of the panel. An external drive component (such as a servo robotic arm) extends the material distribution rod assembly 1 from the end of the cold storage panel along the length direction into the interlayer. When the foaming material is transported to the storage section through the supply pipeline, it will simultaneously diffuse to both sides through the first channel and penetrate downwards through the second channel. Combined with the dynamic operation mode of the material distribution rod assembly 1 gradually withdrawing outwards as the filling process progresses, continuous and uniform filling from the inside to the outside of the panel is achieved, effectively solving the problems of voids and accumulation caused by uneven material self-expansion during traditional side injection, and improving the thermal insulation, sealing performance and structural stability of the cold storage panel.

[0034] Working principle: The feeding rod assembly 1 forms an integral frame through the rigid connection between the upper rod 11 and the lower rod 21. Fasteners pass through the threaded connection of fixing hole 12 and fixing hole 27, ensuring a tight fit and structural stability. The connecting part serves as the core of the feeding interface. The semi-circular connecting hole 16 of the upper rod 11 and the connecting hole 25 of the lower rod 21 are spliced ​​to form a circular channel, which is adapted to the external feeding pipeline. The steps 161 and 251, and steps 262 and 252 of the channel are correspondingly matched, which not only provide axial limit to the pipeline to prevent over-insertion or displacement, but also fit with the pipeline seals (such as sealing rings) to achieve radial sealing, avoiding material leakage during the feeding process and laying the foundation for subsequent stable feeding.

[0035] During the feeding stage, the foamed material enters the storage section through the connecting channels. The conical connecting port 163 and connecting port 253 guide the material flow through their inclined angles, reducing flow resistance. The hollow columnar structure formed by the hollow semi-cylindrical material trough 13 of the upper rod 11 and the material trough 22 of the lower rod 21 serves as a temporary storage space to buffer the feeding pressure. When the output of the external feeding equipment fluctuates, the material trough can temporarily store excess material or replenish insufficient material, avoiding surface bulging caused by sudden increases in local pressure or incomplete filling caused by insufficient pressure. The smooth connection between the storage section and the connecting section achieves a smooth transition of material from input to temporary storage, providing a material source for subsequent uniform discharge.

[0036] The material discharge section achieves precise material diffusion through multi-dimensional channels. The semi-conical openings 14 at both ends of material trough 13 connect with the openings 23 of material trough 22, forming channels 1 extending to both sides in conjunction with the inclined trough 15 and the open trough 24, providing directional material supply to the edge areas between cold storage panels. Multiple sets of equidistant injection holes 28 in material trough 22 serve as channels 2, evenly distributing material to the middle area of ​​the panels. (In actual operation...) Figure 2 In this configuration, the components extend into the space between the panels via an external drive unit and gradually exit as the material is filled. Combined with the coordinated material discharge of channel one (both sides) and channel two (bottom), even when facing uneven or corner structures between the panels, it ensures that the foaming material is covered without any dead angles. This solves the problems of voids and accumulation caused by traditional reliance on self-expanding filling, and improves the bonding strength and insulation uniformity between cold storage panels.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
