Description

Technical Field

[0001] This invention belongs to the field of cold storage construction technology, and in particular relates to a device and method for injecting adhesive into the joints of cold storage panels. Background Technology

[0002] Cold storage panels (side panels) are essential components of the cold storage enclosure structure. However, due to limitations in the processing precision and construction techniques of the panels, seams inevitably exist between them, requiring the use of sealant to seal them. Because the seams are deep, the sealant injection is difficult. When using existing sealant injection equipment, the construction speed is slow, and the density and uniformity of the sealant are poor, making it difficult to seal the seams tightly. This leads to air leakage and cold air loss, seriously affecting the performance of the cold storage. It can even cause problems such as panel deformation and tearing of sealing strips, causing irreversible damage to temperature-sensitive items such as medicines, vaccines, and seafood stored in the cold storage. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a sealant injection device and injection method for panel joints, which can significantly improve the sealant filling rate, improve the sealant distribution uniformity, ensure that the sealant is filled densely, and achieve a tight seal of the joints.

[0004] The technical solution adopted in this invention is: a glue injection device for panel joints, comprising a glue injection tube, a hanging assembly, and a connecting assembly; the glue injection tube includes a glue injection port, a glue outlet hole, and a glue outlet, the glue injection port and the glue outlet hole being disposed opposite to each other at both ends of the glue injection tube, and the glue outlet hole being formed in the tube wall of the glue injection tube; the hanging assembly is inserted into the end of the glue injection tube near the glue injection port, and its two ends protrude from the tube wall; multiple glue injection tubes are arranged side by side, and adjacent glue injection tubes are connected by the connecting assembly.

[0005] Furthermore, the glue injection tube includes multiple glue injection sections, and adjacent glue injection sections are detachably connected along their axial direction.

[0006] Furthermore, the glue injection section includes a glue injection segment and a conical head. One end of the glue injection segment is provided with the glue injection port, and the other end is connected to the conical head. The wall of the glue injection segment is provided with the glue outlet hole. The tip of the conical head is provided with the glue outlet. The conical head of one glue injection segment is inserted into the glue injection port of another glue injection segment.

[0007] Furthermore, the glue injection section is provided with a slot and a connector. The slot is located at the glue injection port, and the connector is located near the conical head. The slot and connector of adjacent glue injection sections are rotatably engaged.

[0008] Furthermore, the slot includes an inlet section and a locking section. The inlet section extends axially along the glue injection section and forms an opening at its outer end. The tightening section is connected to the inner end of the inlet section and extends circumferentially along the glue injection section. The locking connector protrudes from the pipe wall and is adapted to the slot.

[0009] Furthermore, the card slot and the card connector are uniformly arranged along the circumference of the glue injection section.

[0010] Furthermore, the tube wall of the glue injection section is uniformly provided with a plurality of glue outlet holes.

[0011] Furthermore, the connecting assembly includes a sleeve, an adjusting screw, and a fixing clamp. Both ends of the sleeve are threadedly connected to the adjusting screw; the other end of the adjusting screw is connected to the fixing clamp; and the fixing clamp is connected to the glue injection section.

[0012] Furthermore, the mounting assembly also includes a horizontal bar and a snap-fit ​​component. The horizontal bar is arranged opposite to the axis of the glue injection tube and passes through the side wall of the glue injection tube respectively. The protruding end of the horizontal bar is connected by the snap-fit ​​component, and at least one snap-fit ​​component is detachably connected to the horizontal bar.

[0013] A method for injecting adhesive into the joints of cold storage panels, using the aforementioned adhesive injection device for cold storage panel joints, includes the following steps:

[0014] Assemble the glue injection sections according to the depth and length of the joint to form the glue injection tube;

[0015] Install the mounting assembly to fix the glue injection tube to the joint;

[0016] Once the sealant has been filled to the set height, the injection tube is raised, the top injection section is removed, and the mounting assembly is disassembled and installed onto the next injection section.

[0017] The advantages and positive effects of this invention are:

[0018] (1) By setting up an injection tube, the injection tube can be inserted into the joint and the sealant can be injected through the injection hole and the injection port of the injection tube, which can significantly improve the filling rate of the joint sealant and thus improve the overall injection construction efficiency; by setting up multiple injection tubes side by side, the filling rate of the sealant can be further improved, the uniformity of the sealant distribution can be improved, and the sealant inside the joint can be filled densely without cavities, thus achieving a tight seal of the joint.

[0019] (2) By connecting multiple glue injection sections to form a glue injection tube, a continuous operation mode of injecting glue, lifting and disassembling glue injection sections can be realized, which can significantly improve the filling density of the sealant in the joint and effectively avoid defects such as internal cavities and gaps.

[0025] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] This invention proposes a joint glue injection device for cold storage panels, used to inject glue into the joints between cold storage panels to ensure a tight connection between the panels and prevent air leakage and cold air loss. In this embodiment, the cold storage panel refers to the side panel of the cold storage unit. The joint between the panels extends vertically and mainly appears between two adjacent panels on the same wall and at the corner of two walls. The joint has a length, width, and depth, wherein the length is equal to the thickness of the panel, the width is the distance between two adjacent panels, and the depth is equal to the height of the panel. Typically, before applying sealant, both ends of the joint along its length are sealed with plate-like structures, creating a narrow, elongated cavity with an opening at the top. In existing technology, sealant is applied downwards from the top opening using sealant injection equipment. However, due to the depth of the joint and the difficulty of the sealant flowing inwards under its own weight and pressure, the injection speed is slow, and air pockets easily form deep within the joint, resulting in poor density and uniformity of the sealant and the formation of gaps. During cold storage operation, these gaps are prone to air leakage and cold air loss. The continuous loss of cold air not only increases the operating load of the refrigeration system but also makes it difficult for the temperature of the cold storage to stabilize and recover, especially during defrosting cycles or after the doors are opened. Simultaneously, moisture entering the gaps freezes upon contact with the cold air; the expanding ice crystals can widen the joints, causing further expansion of the gaps and creating a vicious cycle. In severe cases, this can lead to deformation of the panels and tearing of the sealing strips, causing irreversible damage to temperature-sensitive items such as medicines, vaccines, and seafood stored inside the cold storage.

[0027] In view of this, embodiments of this application provide a panel joint glue injection device to overcome at least one of the above-mentioned technical problems.

[0028] like Figure 1 As shown, the present invention proposes a glue injection device for panel joints, including a glue injection tube, a hanging assembly, and a connecting assembly; the glue injection tube includes a glue injection port, a glue outlet 2, and a glue outlet 10, with the glue injection port and the glue outlet 10 positioned opposite each other at both ends of the glue injection tube, and the glue outlet 2 being formed in the tube wall; the hanging assembly is inserted into the end of the glue injection tube near the glue injection port, with both ends protruding from the tube wall; multiple glue injection tubes are arranged side by side, and adjacent glue injection tubes are connected by the connecting assembly.

[0029] The aforementioned injection tube has an internal cavity, which is connected to the outside via an injection port, an outlet hole 2, and an outlet port 10. The injection port is used to connect to the injection equipment, and the entire injection tube can extend into the joint of the cold storage panel. During the injection operation, the sealant is introduced into the cavity through the injection port. Under the combined action of its own gravity and fluid flow, it simultaneously overflows outward from the outlet hole 2 and the outlet port 10 and fills the inside of the joint, which can significantly improve the filling rate of the joint sealant and thus improve the overall injection construction efficiency.

[0030] The aforementioned mounting assembly is used to fix the glue injection tube at a predetermined position in the joint. During use, the two ends of the connector protruding from the tube wall can be respectively snapped onto the top surface of the panel on both sides of the joint, thereby achieving convenient, quick installation and stable fixation of the glue injection tube.

[0031] The cold storage panels are relatively thick; in one specific embodiment, the panel thickness can reach 230mm, corresponding to a panel joint length of 230mm. By setting multiple glue injection tubes, the glue application areas of each tube overlap, completely covering the entire length of the joint. This further improves the sealant filling rate, enhances the uniformity of sealant distribution, and ensures that the sealant inside the joint is densely filled without any cavities.

[0032] The aforementioned connecting components are used to connect multiple side-by-side dispensing tubes to form an integrated structure, which can further improve the stability of the device and prevent individual dispensing tubes from shaking or shifting during dispensing operations.

[0033] Furthermore, in this embodiment, the injection tube includes multiple injection sections, which are detachably connected along their axial direction. During the injection process, the injection tube can be lifted upwards according to the filling progress of the sealant inside the joint, and the uppermost injection section can be removed, so that the sealant can immediately fill the cavity space freed up after the injection section is removed. This continuous operation method of simultaneously injecting sealant, lifting, and removing injection sections significantly improves the filling density of the sealant inside the joint, compared to the implementation method of pulling out the injection tube as a whole after all the sealant injection is completed, effectively avoiding defects such as internal cavities and gaps.

[0034] In the above embodiment, the hook assembly is detachably connected to the uppermost glue injection section and can be used to lift the glue injection pipe to facilitate lifting operations by workers; at the same time, after the uppermost glue injection section is removed, the hook assembly can be easily connected to the next glue injection section and snapped onto the storage plate again to fix the glue injection pipe.

[0035] In the above embodiments, the injection tube can be lifted upward according to the filling height of the sealant, and the filling height of the sealant can be obtained by observation; for example, when the sealant is filled to the set position of the bottom injection section, the injection tube is lifted; the set position can be the upper end, middle or bottom end of the axis of the bottom injection section, and there is no limitation here.

[0036] Furthermore, in the embodiments of this application, the glue injection section includes a glue injection segment 9 and a conical head 4. One end of the glue injection segment 9 is provided with a glue injection port, and the other end is connected to the conical head 4. The tube wall of the glue injection segment 9 is provided with a glue outlet hole 2. The tip of the conical head 4 is provided with a glue outlet 10. The conical head 4 of one glue injection section is inserted into the glue injection port of another glue injection section.

[0037] The aforementioned injection section 9 is a hollow tubular structure, and the aforementioned conical head 4 is a hollow conical structure. The injection section 9 and the conical head 4 have a connected cavity. By inserting the conical head 4 into the injection port, multiple injection sections are connected to form a flow channel for the sealant.

[0038] In use, the glue injection tube is set vertically. The conical head 4 of the upper glue injection section is inserted into the glue injection port of the lower glue injection section. The sealant is introduced from the top glue injection section and flows into the next glue injection section through the glue outlet 10, so that the sealant flows from top to bottom in the glue injection tube until it flows out from the glue outlet of the lowest glue injection section. At the same time, the sealant can also overflow to the outside of the tube wall through the glue outlet 2 and flow down the tube wall, eventually filling the deep joint.

[0039] Furthermore, in this embodiment, the glue injection section 9 is provided with a slot 1 and a connector 3. The slot 1 is located at the glue injection port, and the connector 3 is located near the conical head 4. The slots 1 and connectors 3 of adjacent glue injection sections are rotated and engaged.

[0040] When the slot 1 and the connector 3 are engaged, the conical head 4 of the grouting section can be inserted into another grouting section, achieving end-to-end alignment and connection between adjacent grouting sections. At the same time, the slot 1 and the connector 3 are locked by rotation, forming a continuous and stable grouting channel to prevent the grouting section from falling off during the grouting process. The grouting sections can be quickly and easily assembled, connected, and disassembled by rotation.

[0041] Furthermore, in this embodiment of the application, the slot 1 includes an inlet section and a locking section. The inlet section extends axially along the injection joint and forms an opening at its outer end. The tightening section is connected to the inner end of the inlet section and extends circumferentially along the injection joint. The locking connector 3 protrudes from the pipe wall and is adapted to the slot 1.

[0042] The aforementioned slot 1 penetrates the thickness of the pipe wall, and the inlet section and locking section are connected to form an L-shaped structure. The outer end of the inlet section extends to the edge of the injection section, forming an opening. In use, the clamping connector 3 is inserted through the opening and moved to the inner end of the inlet section. Then, the injection section is rotated to move the clamping connector 3 further to the inner end of the tightened section, thereby locking and fixing the clamping connector 3. Since the injection section is mainly subjected to gravity and the impact force brought by the flow of sealant during the injection process, it will not cause the injection section to rotate, ensuring a stable connection between the injection sections. When it is necessary to disassemble the injection section, simply rotate the injection section in the opposite direction and then remove the clamping connector 3 to release the connection between the injection sections. The operation is simple and quick.

[0043] In the above embodiments, the slot 1 and the connector 3 are uniformly arranged along the circumference of the glue injection section 9; the slot 1 and the connector 3 correspond one-to-one, and two, three or four can be uniformly arranged along the circumference of the glue injection section; in this embodiment, since the joint width is narrow and the diameter of the glue injection section is small, two slots 1 and two connectors 3 are provided respectively, and they are arranged opposite each other along the radial direction of the glue injection section.

[0044] In this embodiment, the slot 1 and the connector 3 are arranged opposite each other along the axial direction of the glue injection section, and the connector 3 is aligned with the inlet section.

[0045] In this embodiment, the snap-fit ​​connector 3 is positioned near the connection between the glue injection section 9 and the conical head 4; the glue injection section is made of PVC material, and the outer diameter of the conical head 4 is slightly smaller than the inner diameter of the glue injection section 9; when connecting two glue injection sections, the side wall of the snap-fit ​​connector 3 can deform slightly, and under the pressure of external force and the guidance of the conical head 4, it can be smoothly inserted into another glue injection section; at this time, an interference fit is formed between the side walls of the two glue injection sections, which can further improve the stability of the connection.

[0046] Furthermore, in this embodiment, the wall of the glue injection section 9 is uniformly provided with multiple glue outlet holes 2, which can further improve the glue injection efficiency and make the sealant more evenly distributed around the glue injection tube after overflowing, thereby improving the uniformity of sealant filling.

[0047] Preferably, the dispensing holes 2 are evenly distributed along the axial and circumferential directions of the dispensing section 9, arranged in an array; in a specific embodiment, the outer diameter of the dispensing section 9 is 50mm, and four rows of dispensing holes 2 are equally spaced along the circumferential direction of the dispensing section 9, with the distance between adjacent dispensing holes 2 being 50mm along the axial direction of the dispensing section 9.

[0048] Furthermore, in this embodiment, the connecting assembly includes a sleeve 8, an adjusting screw 6, and a fixing clamp 5. Both ends of the sleeve 8 are threadedly connected to the adjusting screw 6; the other end of the adjusting screw 6 is connected to the fixing clamp 5; and the fixing clamp 5 is connected to the glue injection joint. By rotating the sleeve 8, the adjusting screw 6 can move inward or outward from the sleeve 8, thereby adjusting the connection length between the two, and consequently adjusting the distance between the two parallel glue injection tubes to meet the usage requirements of different joint lengths.

[0049] In one specific embodiment, the joint length is 230mm, and two glue injection tubes are arranged side by side. By adjusting the connecting components, the distance between the glue injection tubes is 60mm. In use, the device is placed in the middle of the joint, so that the distance from the two ends of the joint length direction is approximately equal, so that uniform filling can be achieved.

[0050] In the above embodiment, the fixing tube clamp 5 has a curved surface structure, the curvature of which is the same as the outer wall of the glue injection section 9, and can be attached to the glue injection section 9.

[0051] In one specific embodiment, the sleeve 8, adjusting screw 6, and fixing clamp 5 are all made of plastic. The fixing clamp 5 is heat-fused to the glue injection section 9. One end of the adjusting screw 6 is heat-fused to the fixing clamp 5 and is provided with external threads. Both ends of the sleeve 8 are provided with matching internal threads. The two adjusting screws 6 are respectively threaded to both ends of the sleeve 8. By rotating the sleeve 8, the connection length of the three can be adjusted. Preferably, the adjusting screw 6 is also provided with a fixing nut 7 to control the length range of the adjusting screw 6 that can be inserted into the sleeve 8.

[0052] In one specific embodiment, multiple connecting components are evenly arranged between two injection joints along the length direction of the injection joint to further improve the stability of the overall structure.

[0053] In the above embodiment, the adjusting screw 6 and the fixing tube clamp 5 are fixed on the glue injection section 9 of each glue injection section. Before use, multiple glue injection sections are assembled and connected to form a glue injection tube. Then, the adjusting screw 6 on the two glue injection tubes is connected through the sleeve 8 to realize the connection of the two glue injection tubes.

[0054] Furthermore, in this embodiment, the mounting assembly also includes a horizontal rod 11 and a snap-fit ​​member 12. The horizontal rod 11 is arranged opposite to each other along a direction perpendicular to the axis of the glue injection tube and passes through the side wall of the glue injection tube respectively. The protruding ends of the horizontal rod 11 are connected by the snap-fit ​​member 12, and at least one snap-fit ​​member 12 is detachably connected to the horizontal rod 11.

[0055] In one specific embodiment, the inner side of the slot 1 of the glue injection section 9 is provided with four through holes. The four through holes are at the same height. Two of the through holes can be connected to form a straight line, and the other two through holes can also be connected to form another straight line parallel to it. Both straight lines are perpendicular to the axis of the glue injection section 9. The transverse rod 11 passes through two through holes along the above-mentioned straight line direction, thereby fixing it to the glue injection section 9. The two ends of the transverse rod 11 protrude from the side wall of the glue injection section 9 to form through-ends. The through-ends on the same side of the glue injection section 9 are connected by snap-fit ​​pieces 12. When the glue injection tube extends into the joint, the snap-fit ​​pieces 12 can snap onto the top surface of the panel on both sides of the joint, thereby fixing the glue injection tube. When it is necessary to lift the glue injection tube, the operator can lift the glue injection tube through the snap-fit ​​pieces 12, then remove the top glue injection section, remove the hanging assembly and install it on the next glue injection section, and fix the glue injection tube to the panel again before proceeding with the subsequent glue injection operation.

[0056] In one specific embodiment, one snap-fit ​​component 12 is fixed to one end of the two transverse rods 11, and the other snap-fit ​​component 12 has an assembly hole through which the other end of the transverse rod 11 passes and is secured by a fastening nut. This configuration allows for more convenient installation and removal of the mounting assembly.

[0057] Preferably, the dispensing hole 2 can be used as a perforation for installing the mounting component, thereby further simplifying the structure of the dispensing tube.

[0058] In the above embodiment, the transverse rod 11 is perpendicular to the length direction of the connecting assembly.

[0059] This application also proposes a method for injecting adhesive into the joints of cold storage panels, using the aforementioned adhesive injection device for cold storage panel joints, including the following steps:

[0060] S1. Assemble the glue injection section according to the depth and length of the joint to form the glue injection tube;

[0061] Specifically, two vertically arranged glue injection sections are connected through the slot 1 and the connector 3, and two parallel glue injection sections are connected through the sleeve 8; repeat the above actions to connect multiple vertically arranged glue injection sections to form a glue injection tube, and connect multiple glue injection tubes side by side.

[0062] S2. Install the mounting assembly and fix the glue injection tube to the joint;

[0063] Install the hanging components on the topmost glue injection section, and insert the lower end of the glue injection tube into the joint so that the snap fastener 12 snaps onto the top of the panel on both sides of the joint.

[0064] Then, the dispensing port 10 of the dispensing equipment can be inserted into the dispensing port at the top of the dispensing tube to control the sealant to flow out evenly and start the dispensing operation.

[0065] S3. After the sealant is filled to the set height, lift the injection tube, remove the top injection section, and disassemble and install the mounting component on the next injection section.

[0066] Observe the level of sealant in the joint. When it fills to the set position of the bottom injection section, stop the injection and lift the injection tube upwards using the hanging component. Then remove the top injection section, remove the lifting component, and install it on the next injection section.

[0067] Then, perform the sealant injection operation again, repeating step S3 above, until the sealant in the joint is filled to the top of the joint, and then the injection tube can be removed; if the sealant level in the joint does not meet the filling requirements after the injection tube is removed, it can be filled again using the injection equipment.

[0068] The advantages and positive effects of this invention are:

[0069] (1) By setting up an injection tube, the injection tube can be inserted into the joint and the sealant can be injected through the injection hole and the injection port of the injection tube, which can significantly improve the filling rate of the joint sealant and thus improve the overall injection construction efficiency; by setting up multiple injection tubes side by side, the filling rate of the sealant can be further improved, the uniformity of the sealant distribution can be improved, and the sealant inside the joint can be filled densely without cavities, thus achieving a tight seal of the joint.

[0070] (2) By connecting multiple glue injection sections to form a glue injection tube, a continuous operation mode of injecting glue, lifting and disassembling glue injection sections can be realized, which can significantly improve the filling density of the sealant in the joint and effectively avoid defects such as internal cavities and gaps.

[0071] (3) By setting the slots and connectors, the connection and disassembly of the glue injection section can be completed conveniently and efficiently; the connection of each component is stable, ensuring the smooth progress of the glue injection operation; the overall structure is simple and easy to manufacture and use.

[0072] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
