Description

Technical Field

[0001] This utility model relates to the field of cold storage panel production technology, and in particular to a curved arm conveyor structure for interlayer foaming injection of cold storage panels. Background Technology

[0002] In the construction and manufacturing of cold storage facilities, cold storage panels are a key component of the enclosure structure, and their quality directly affects the thermal insulation performance, energy consumption, and service life of the cold storage. Cold storage panels typically consist of double-sided panels (such as color steel plates or stainless steel plates) and an intermediate insulation core layer. Interlayer foaming injection is an important process for forming the insulation core layer. This involves using a specific conveying structure to deliver a die for injecting foaming material into the interlayer space of the cold storage panel, completing the injection and filling of the foaming material, and allowing the material to solidify in the interlayer to form the insulation layer.

[0003] In the current cold storage panel production process, the traditional fixed-rail foaming machine, while capable of interlayer foaming injection, has a large footprint due to the increasing scale of production and the growing demand for efficient use of production space. This not only leads to crowded production workshops and limits the flexibility of equipment layout, but also makes adjustments cumbersome and time-consuming when foaming injection for cold storage panels of different specifications and sizes, making it difficult to adapt to diverse production needs and reducing production efficiency. Therefore, it is necessary to design an articulated boom conveyor structure for interlayer foaming injection of cold storage panels.

[0004] 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

Detailed Implementation

[0027] 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.

[0028] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-6As shown in the figure, the present invention provides a curved boom conveyor structure for interlayer foaming injection of cold storage panels, including a support platform 1, on which a storage tank 11 for storing foaming raw materials is provided, and a conveying mechanism 2 is connected to the support platform 1. The conveying mechanism 2 is used to send the die head for filling foaming material into the space between the cold storage panels, and the conveying mechanism 2 includes an installation part provided on one side of the support platform 1. The installation part includes an installation frame 21 provided on one side of the support platform 1 and arranged vertically, and the installation frame 21 is connected to the side of the support platform 1 by fasteners through a side fixing bracket 22 to ensure the overall structural stability of the installation part;

[0030] And a guide cover 1 23 with an arc-shaped structure is fixed through the top of the mounting frame 21, and a guide cover 24 with the same arc-shaped structure is movably inserted through the bottom of the mounting frame 21. One end of the guide cover 24 is movably fitted onto the guide cover 1 23. The guide cover 1 23, the guide cover 24 and the mounting frame 21 are all hollow structures, and the guide cover 1 23, the guide cover 24 and the mounting frame 21 have hollow parts that are connected to each other.

[0031] A movable part is provided on the support platform 1. The movable part includes a guide rail 27 fixed on the support platform 1, and a chain plate 25 is provided in the guide rail 27. The chain plate 25 is composed of plate units that are hinged to each other, chain link connectors that connect multiple plate units, and a chain that cooperates with the chain link connectors. The chain is arranged along the side of the chain plate 25 and is fixedly connected to the chain link connectors to form a complete transmission structure. The linear movement of the chain plate 25 is constrained by the groove structure of the guide rail 27 to prevent it from shifting laterally during the horizontal conveying stage. The drag chain 26 is used to store the pipes and cables connecting the mold head. At the same time, a slide (not shown in the figure) is provided on the side of the guide rail 27. The drag chain 26 is provided in the slide and moves synchronously with the chain plate 25, which protects the pipes from bending damage and avoids the pipes from getting tangled and affecting the operation of the equipment.

[0032] The guide cover 23 provides an arc-shaped guide path for the chain plate 25 to run at the top of the device, and the guide cover 24 cooperates with the guide cover 23 to provide an arc-shaped channel for the chain plate 25 to turn and convey at the bottom. The hollow and connected design provides continuous passage space for the chain plate 25, so that the chain plate 25 can run smoothly in the conveying mechanism 2.

[0033] One end of the chain plate 25 extends into the hollow cavity connecting the first guide cover 23, the second guide cover 24, and the mounting frame 21, and protrudes from one end of the second guide cover 24. At the same time, a support plate 231 is fixed on the bottom surface of one end of the first guide cover 23 to provide auxiliary support for the chain plate 25. The support plate 231 supports the chain plate 25 at the end of the first guide cover 23 to prevent the chain plate 25 from sagging or shifting due to uneven force at the end. A support plate 241 is fixed on the bottom surface of one end of the second guide cover 24 to provide auxiliary support for the chain plate 25. The support plate 241 has the same function as the support plate 231, providing auxiliary support for the chain plate 25 at the end of the second guide cover 24 to ensure the running stability of the chain plate 25 at the end connection.

[0034] A feeding assembly 6 is provided on one end of the chain plate 25 that protrudes from the guide cover 24. The feeding assembly 6 includes a cover 62 that is fixedly engaged with the end of the chain plate 25 that protrudes from the guide cover 24, that is, fixed on the plate unit of the chain plate 25. The cover 62 has a concave structure and an opening at one end. A filling die head 61 is inserted and fixed at the end of the cover 62 away from the guide cover 24. A hose 611 is connected to one end of the filling die head 61. The hose 611 is located inside the chain plate 25 and is connected to the storage tank 11 after passing through one end of the chain plate 25.

[0035] A first clamp part 63 for fixing the hose 611 is provided at the top of the inner wall of the housing 62. The first clamp part 63 includes a support base 631 fixed to the top of the inner wall of the housing 62. Two sets of U-shaped sleeves 632 are fixed to the support base 631 by nuts. The sleeves 632 cooperate with the support base 631 to fix the hose 611. At the same time, a second clamp part 64 with a similar structure to the first clamp part 63 is provided on the inner wall of the plate unit of the chain plate 25 (in combination with the first clamp part 63). Figure 6 The second clamp 64 is also used to secure the hose 611;

[0036] A drive assembly 3 for moving the chain plate 25 is provided on the guide cover 23. The drive assembly 3 includes two sets of side plates 31 fixed to the bottom surface of the guide cover 23. A connecting roller 32 is connected between the two sets of side plates 31 through a bearing. A sprocket 37 is fixed near both ends of the connecting roller 32. The sprocket 37 meshes with the chain of the chain plate 25 to provide power transmission for the movement of the chain plate 25. At the same time, a sprocket is fixed to one end of the connecting roller 32 that passes through one set of side plates 31. A servo motor 34 is fixedly installed on the top surface of the guide cover 23. The output end of the servo motor 34 is fixedly connected to the sprocket 2 35. The sprocket 2 35 and the sprocket 1 33 are connected through the chain part 36. When the servo motor 34 runs, it drives the connecting roller 32 to rotate in sequence through the sprocket 2 35, the chain part 36, and the sprocket 1 33. Then, by means of the meshing of the sprocket 3 37 with the chain of the chain plate 25, the chain plate 25 is driven to move along the path formed by the guide cover 23 and other components.

[0037] It should be noted that in the actual material supply process, the storage tank 11 serves as the storage source for the foaming material. Its outlet is usually connected to a power conveying device (such as a gear pump or peristaltic pump). The pressure generated by the pump continuously presses the foaming material into the hose 611. The hose 611, with its own flexibility, extends from the outlet end of the storage tank 11, passes through the pre-set pipe opening at the end of the chain plate 25, and enters the interior of the chain plate 25. It is laid along the reserved channel inside the plate unit of the chain plate 25. It is fixed to the inner wall of the plate unit of the chain plate 25 by the second pipe clamp 64 and the first pipe clamp 63 is fixed to the top of the inner wall of the cover 62. This double fixation ensures that the hose 611 will not shift or fall off when the chain plate 25 moves with the transmission mechanism (including turning, translation, etc.). At the same time, the edges of the internal channel of the chain plate 25 are rounded to avoid wear on the hose 611. Finally, the foaming material is conveyed to the filling die head 61 through the hose 611, and then the filling die head 61 delivers the material according to production needs.

[0038] To accommodate the filling of multi-layer assembled cold storage panels, an adjustment component 5 is provided on the mounting frame 21. The adjustment component 5 includes a motor 51 fixed horizontally on the side of the mounting frame 21. One end of the motor 51 passes through the mounting frame 21 and is fixed with a gear (not shown in the figure). At the same time, a rack 52 that meshes with the gear is fixed on the side of the guide cover 24. When the motor 51 is running, the gear and rack 52 mesh and drive the guide cover 24 to move in the vertical direction of the mounting frame 21, flexibly adjusting the height position of the feeding component 6 at one end of the guide cover 24.

[0039] In this application, in order to cooperate with the adjustment component 5, the bottom of the guide cover 23 is provided with a tensioning mechanism (this mechanism is prior art and will be briefly described here). The tensioning mechanism includes two sets of symmetrical vertical plates 38 fixed on the outer side of the bottom of the guide cover 23. An adjustment screw 39 is passed through the vertical plates 38. A movable sliding seat (not shown in the figure) is sleeved on the adjustment screw 39. A tensioning roller with a tensioning sprocket is installed in the sliding seat. The tensioning sprocket meshes with the chain of the chain plate 25. One end of the adjustment screw 39 passes through the vertical plate 38 and is connected to a reduction motor (not shown in the figure) fixed on the side of the guide cover 23.

[0040] When it is necessary to adjust the tension of the chain plate 25, the geared motor is started to drive the adjusting screw 39 to rotate, so that the sliding seat, tensioning roller and tensioning sprocket move synchronously. The tension of the chain plate 25 is changed by the cooperation between the tensioning sprocket and the chain of the chain plate 25. Especially when the guide cover 24 moves in the vertical direction and drives the associated chain plate 25 segment to rise and fall synchronously, the geared motor will adjust the tensioning mechanism synchronously to compensate for the change in the length of the chain plate 25 in real time, ensuring that the chain plate 25 always maintains a suitable tension and stably meshes with the sprocket 37 of the drive component 3, ensuring smooth overall transmission.

[0041] It should be noted that when the guide cover 24 moves vertically, it will drive the chain plate 25 associated with it to rise and fall synchronously in sections. At this time, the reduction motor will adjust the tensioning mechanism synchronously, and the tensioning mechanism will compensate for the change in the length of the chain plate 25 in real time, thereby ensuring that the chain plate 25 and the transmission components such as the sprocket 37 always maintain effective engagement.

[0042] Meanwhile, a pressing assembly 4 for restricting the cover 62 is provided on the second support plate 241. The pressing assembly 4 includes two sets of support frames 41 fixed on the second support plate 241. A cylinder 42 is fixedly installed on the top of the support frame 41, and a bearing seat 43 is slidably provided on the inner wall of the support frame 41. The telescopic end of the cylinder 42 is connected to the bearing seat 43, which can drive the bearing seat 43 to slide along the inner wall of the support frame 41. A pressing roller 44 is installed between the two sets of bearing seats 43 through a bearing. The pressing roller 44 is in contact with the surface of the cover 62. With the telescopic action of the cylinder 42, the pressing roller 44 is driven to move up and down to press or release the cover 62, thereby restricting the position of the cover 62 and ensuring that it maintains a stable posture during operation, in conjunction with the filling and other operations of the equipment.

[0043] It should be noted that a PLC control device is installed on the support platform 1. This PLC control device can regulate the start and stop and speed of the servo motor 34 of the drive component 3, the operation of the motor 51 of the adjustment component 5, the extension and retraction of the cylinder 42 of the holding component 4, and the working status of the material supply power device (such as a gear pump) of the storage tank 11. According to the preset program or real-time instructions, the operation of each component is adjusted.

[0044] Working principle: First, before the equipment starts, the foaming raw material is prepared in the storage tank 11. The raw material is pressed into the hose 611 by the power conveying device (such as a gear pump) and conveyed to the filling die head 61 through the internal channel of the chain plate 25 to complete the material supply preparation. The servo motor 34 of the drive component 3 starts and drives the connecting roller 32 to rotate through the second sprocket 35, the chain part 36, and the first sprocket 33. The third sprocket 37 on the connecting roller 32 meshes with the chain of the chain plate 25, driving the chain plate 25 to circulate along the path formed by the guide rail 27, the first guide cover 23, and the second guide cover 24. The drag chain 26 moves synchronously with the chain plate 25 to protect the pipeline from damage. At this time, the feeding component 6 moves to the initial position with the chain plate 25, and the cylinder 42 of the holding component 4 extends, driving the holding roller 44 to press down the cover 62 to ensure its stable posture.

[0045] Secondly, in response to the filling requirements of multi-layer cold storage panels, the motor 51 of the adjusting component 5 operates, and through the meshing transmission of gears and racks 52, it drives the guide cover 24 to move vertically along the mounting frame 21, adjusting the height of the feeding component 6 to the appropriate position. During this process, the guide cover 24 drives the associated chain plate 25 to rise and fall synchronously, and the reduction motor of the tensioning mechanism starts synchronously to compensate for the length change of the chain plate 25 in real time, ensuring that it is always stably meshed with the sprocket 37 and ensuring smooth transmission. At the same time, the hose 611 is fixed by the pipe clamp part 1 63 and the pipe clamp part 2 64, and deforms flexibly with the chain plate 25 to maintain the smooth material supply path.

[0046] Finally, the chain plate 25 drives the filling die head 61 to enter from the interlayer inlet of the cold storage panel and slowly move from one end to the other along the interlayer cavity. During the process, the foaming material is evenly injected into the interlayer gap to complete the filling operation. After the filling is completed, the chain plate 25 moves in the opposite direction to drive the feeding component 6 to exit the interlayer of the cold storage panel. The cylinder 42 of the holding component 4 retracts and drives the holding roller 44 to move up to release the cover 62. The adjusting component 5 drives the guide cover 24 to reset to the initial height. The equipment is ready for the next operation cycle. The whole process realizes the automated conveying and filling of interlayer foaming of multi-layer cold storage panels.
