Description

Technical Field

[0001] This application relates to the field of coating edge sealing product preparation technology, and in particular to an edge sealing product preparation device. Background Technology

[0002] When processing products with coated edges, the aerogel felt roll material, after being unrolled and coated, needs to be cut into sheets, and the cut surfaces of the sheets are then coated with paint. Taking a thin-sheet aerogel insulation pad as an example, the sheet insulation pad needs to be coated with the same paint on all six surfaces. The conventional manufacturing process involves unrolling and coating the incoming material, then cutting it into segments of a specified length, and then using a cutting machine to cut the segments into rectangular pieces. At this point, the two largest surfaces of the rectangular pieces are coated with paint. A stack of rectangular pieces is then neatly arranged in a hopper, and the operator manually coats one side at a time, one at a time, completing the coating in two coats, ensuring that all six surfaces of the rectangular pieces are coated with the same paint. After each coat, the operator uses a blower to loosen the entire stack of products and continues blowing for a period of time until the paint is completely dry and cured. The coating used in sheet-like aerogel thermal insulation pads typically cures in tens of seconds at room temperature. Each stack contains hundreds of sheets, requiring them to be dispersed within these seconds; otherwise, they will stick together, resulting in poor quality. This process necessitates operators repeatedly moving the blower to disperse the sheets within a short period, making it quite labor-intensive. Utility Model Content

[0003] In view of this, this application provides a sealing product preparation device to solve the problem that when blowing away products, operators need to repeatedly move the blower to blow away the products in a short period of time, which results in high labor intensity.

Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0030] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0031] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0032] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another.

[0037] This application provides an edge-sealing product preparation device, such as... Figures 1 to 6 As shown, the edge-banding product preparation equipment includes a drive module 11, an air knife assembly 2, and a hopper assembly 3. The hopper assembly 3 supports the material 4. The drive module 11 is connected to the air knife assembly 2 to drive the air knife assembly 2 to move. The air knife assembly 2 includes an air inlet and an air outlet. The air inlet is connected to an air source, and the air outlet faces the hopper assembly 3. In this way, the air knife assembly 2 can blow away the material 4 on the hopper assembly 3. Since the movement of the air knife assembly 2 is driven by the drive module 11, there is no need for the operator to hold a blower to blow away the material, reducing the labor intensity of the operator.

[0038] Optionally, material 4 can be obtained by: first, unwinding and coating the roll material so that the two surfaces with the largest area of ​​the roll material are coated with paint; then, cutting the roll material into rectangular sheets; and then stacking multiple rectangular sheets along a first direction L1 to form material 4, where the first direction L1 is parallel to the thickness direction of the rectangular sheets. Figure 3 As shown, material 4 includes two first surfaces 41, two second surfaces 42, and two third surfaces 43. The two first surfaces 41 are located on opposite sides of material 4 in a first direction L1, the two second surfaces 42 are located on opposite sides of material 4 in a second direction L2, and the two third surfaces 43 are located on opposite sides of material 4 in a third direction L3. The first direction L1, the second direction L2, and the third direction L3 are all perpendicular to each other. Before using the edge-sealing product preparation apparatus of this application, the two first surfaces 41 of material 4 have been coated with paint, while the two second surfaces 42 and the two third surfaces 43 have not been coated with paint.

[0039] In the embodiments of this application, such as Figure 1 As shown, the edge-sealing product preparation equipment also includes a frame 5, a housing 6, and a mounting platform 71. The mounting platform 71 can be fixed on the frame 5 and can be a plate-like structure. The housing 6 is fixed on the mounting platform 71, and the air knife assembly 2 is located inside the housing 6. An opening 64 is provided on the housing 6, and the hopper assembly 3 can be slidably connected to the mounting platform 71 so that the hopper assembly 3 can enter into the housing 6 or be moved out of the housing 6 through the opening 64. In this way, after coating is applied to one second surface 42 and one third surface 43 of the material 4 on the outside of the housing 6, the hopper assembly 3 can be moved into the housing 6 through the opening 64. The air knife assembly 2 blows the material away inside the housing 6, which can reduce the impact of powder scattering on the operator during the blowing process.

[0040] Furthermore, such as Figure 2 , Figure 4 and Figure 5As shown, a sliding groove 711 is provided on the placement platform 71. Part of the sliding groove 711 is located outside the box body 6, and the other part of the sliding groove 711 extends into the interior of the box body 6 through the opening 64. Part of the hopper assembly 3 is located inside the sliding groove 711, and the hopper assembly 3 can slide along the sliding groove 711, so that the hopper assembly 3 can enter into the interior of the box body 6 or move out of the interior of the box body 6.

[0041] In the embodiments of this application, such as Figure 2 and Figure 3 As shown, the hopper assembly 3 includes a support 31, which comprises a first connecting plate 311, a second connecting plate 312, two fixing plates 313, and two mounting plates 314. The two fixing plates 313 are spaced apart, and each fixing plate 313 is fixed with a mounting plate 314. The two mounting plates 314 are connected by the first connecting plate 311. The bottoms of the two fixing plates 313 are connected by the second connecting plate 312. Optionally, the mounting plates 314 and the fixing plates 313, as well as the mounting plates 314 and the first connecting plate 311, can be fixed with screws.

[0042] Furthermore, the second connecting plate 312 is provided with four guide wheels 315, two of which are located on the same side of the second connecting plate 312, and the other two are located on the other side of the second connecting plate 312. The guide wheels 315 are in contact with the bottom of the sliding groove 711, so that the bracket 31 can slide within the sliding groove 711.

[0043] like Figure 4 and Figure 5 As shown, limit strips 72 can be provided on both sides of the sliding groove 711. The limit strips 72 can be fixed to the mounting platform 71 by bolts. Part of the limit strips 72 extends above the sliding groove 711. The part of the limit strips 72 extending above the sliding groove 711 has a limit groove 721. Part of the guide wheel 315 protrudes from the sliding groove 711 and is located in the limit groove 721. This allows the limit strips 72 to guide the movement of the guide wheel 315, thereby improving the stability of the movement of the hopper assembly 3.

[0044] Optionally, such as Figure 3 As shown, an abutment block 73 is provided on the portion of the limiting strip 72 located inside the housing 6. The portion of the abutment block 73 extends relative to the limiting strip 72 toward the center of the sliding groove 711. The abutment block 73 can abut against the bracket 31 to restrict the movement of the hopper assembly 3. When the hopper assembly 3 abuts against the abutment block 73, the hopper assembly 3 is in a predetermined position, and the hopper assembly 3 is completely inside the housing 6. At this time, the air outlets on the first air knife 21 and the second air knife 22 (described below) face the material.

[0045] like Figure 4As shown, the hopper assembly 3 also includes two clamping plates 32 and two force-applying components 33. Both force-applying components 33 are fixed to the bracket 31 and are respectively connected to the two clamping plates 32. The two force-applying components 33 can apply force to the two clamping plates 32 respectively, allowing the two clamping plates 32 to move closer to or further away from each other. After the two clamping plates 32 clamp the material 4, the operator can apply paint to the material 4. After painting, the two clamping plates 32 can be moved away from each other to facilitate subsequent blowing of the material 4.

[0046] Preferably, the force-applying component 33 is a push-pull quick clamp. The push-pull quick clamp is fixed on the fixed plate 313, and the push rod of the push-pull quick clamp passes through the fixed plate 313 and the mounting plate 314 and is connected to the clamping plate 32. The handle of the push-pull quick clamp can realize the locking and releasing of the push-pull quick clamp, so as to drive the clamping plate 32 to move, thereby realizing the two clamping plates 32 moving closer or further apart from each other.

[0047] Furthermore, such as Figure 4 As shown, the hopper assembly 3 also includes a first support plate 34 and a second support plate 35. Both the first support plate 34 and the second support plate 35 are fixed on the bracket 31. A second surface 42 contacts the first support plate 34, and a third surface 43 contacts the second support plate 35, thereby supporting the material 4. At this time, only the second surface 42 and the third surface 43 are exposed, which makes it convenient for the operator to apply paint to the exposed second surface 42 and the third surface 43.

[0048] Preferably, the angle between the second direction L2 and the direction of gravity is an acute angle, that is, the material 4 is placed at an angle, which facilitates the application of coatings.

[0049] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the edge-sealing product preparation equipment also includes a hot air blower 81, which is fixed to the inner wall of the housing 6. The hot air blower 81 is located on the side of the air knife assembly 2 facing away from the mounting platform 71. When the air knife assembly 2 begins to disperse the material 4, the hot air blower 81 only blows air and does not heat it. After the air knife assembly 2 has initially dispersed the material 4, the hot air blower 81 starts its heating function to blow hot air into the housing 6 to accelerate the curing of the coating.

[0050] Furthermore, the edge-banding product preparation equipment also includes a temperature detector, such as... Figure 6 As shown, a first mounting hole 62 is provided on the enclosure 6, and a temperature detector is fixed on the first mounting hole 62. The temperature detector can detect the temperature inside the enclosure 6 to achieve real-time monitoring of the internal temperature of the enclosure 6. Optionally, the temperature detector is a thermocouple.

[0051] Furthermore, the edge banding product preparation equipment also includes a temperature controller, which is communicatively connected to a temperature detector and can control whether the hot air blower 81 heats up. During edge banding product preparation, the chamber 6 can be set to remain within a preset range based on actual needs. The temperature detector can monitor the temperature of the chamber 6 in real time and send a temperature signal to the temperature controller. When the temperature inside the chamber 6 is lower than the lower limit of the preset range, the temperature controller controls the hot air blower 81 to heat up; when the temperature inside the chamber 6 is higher than the upper limit of the preset temperature, the temperature controller controls the hot air blower 81 to stop heating, thereby maintaining the temperature inside the chamber 6 within the preset range.

[0052] In addition, the edge sealing monitoring device also includes a material detector. A second mounting hole 63 can be provided on the housing 6, and the material detector is installed in the second mounting hole 63. The material detector is configured to detect material 4 when the hopper assembly 3 moves to a predetermined position. When the material detector detects material 4, material 4 is inside the housing 6. At this time, the air knife assembly 2 starts to intake air to disperse material 4.

[0053] Alternatively, the material detector can be a photoelectric sensor, a proximity sensor, or the like.

[0054] In the embodiments of this application, such as Figure 2 As shown, the air knife assembly 2 includes a first air knife 21, a second air knife 22, and a connecting mechanism 23. Both the first air knife 21 and the second air knife 22 have air inlets and outlets. The extending directions of the first air knife 21 and the second air knife 22 intersect. Both the first air knife 21 and the second air knife 22 are fixed to the connecting mechanism 23. A portion of the connecting mechanism 23 extends from the housing 6. The connecting mechanism 23 is connected to the drive module 11, enabling the drive module 11 to drive the first air knife 21 and the second air knife 22 to move. Because the extending directions of the first air knife 21 and the second air knife 22 intersect, the first air knife 21 and the second air knife 22 can blow air onto different parts of the material 4, further improving the blowing efficiency. Preferably, the extending directions of the first air knife 21 and the second air knife 22 are perpendicular.

[0055] Furthermore, a mounting bracket 12 is fixed to the bottom of the drive module 11. The adapter mechanism 23 includes an adapter 231 and a moving rod 232. The adapter 231 is L-shaped, and the first air knife 21 and the second air knife 22 are respectively fixed on the adapter 231. The adapter 231 is located inside the housing 6. A moving channel 61 is provided on the housing 6. One end of the moving rod 232 is connected to the adapter 231, and the other end of the moving rod 232 passes through the moving channel 61 and is connected to the mounting bracket 12. When the drive module 11 drives the air knife assembly 2 to move, the moving rod 232 slides within the moving channel 61.

[0056] Optionally, the drive module 11 can be a linear module.

[0057] In the embodiments of this application, such as Figure 1 As shown, there are two housings 6, two air knife assemblies 2, and two hopper assemblies 3. The two housings 6 are spaced apart, and the two air knife assemblies 2 are located inside the two housings 6 respectively. Both air knife assemblies 2 are connected to the drive module 11. The two hopper assemblies 3 correspond to the two housings 6 respectively, and the hopper assemblies 3 can enter or exit the corresponding housing 6. In this way, after the second surface 42 and the third surface 43 of the material 4 on one hopper assembly 3 are coated and pushed into the housing 6, the material 4 on the other hopper assembly 3 can be coated, thereby improving work efficiency.

[0058] In addition, the edge banding product preparation equipment also includes a protective cover 82, which is fixed to the top of the two boxes 6, and the drive module 11 is fixed to the bottom of the protective cover 82 and located between the two boxes 6.

[0059] The operating procedure of the edge-sealing product preparation device of this application is as follows: The operator places a rectangular sheet on the hopper assembly 3 and arranges it neatly to form material 4. Then, the material 4 is quickly clamped by two clamping plates 32. The operator uses a roller brush to coat a second surface 42 and a third surface 43. After the coating is completed, the operator uses the force application component 33 to move the two clamping plates 32 away from each other to facilitate subsequent blowing. Then, the operator pushes the hopper assembly 3 into the box 6. At this time, the drive module 11 drives the air knife assembly 2 to move. When the hopper assembly 3 reaches the predetermined position, the material detector detects the material 4, and the air knife assembly 2 starts to intake air. During the movement of the air knife assembly 2, the material 4 is blown away by the air force, and excess coating on the edges is blown away to prevent the products from sticking together. At this time, the hot air blower 81 on the upper part of the box 6 starts and blows air. After blowing back and forth for a predetermined number of times, the heating function of the hot air blower 81 is activated to bake the initially dispersed material 4. After baking until completely dry, pull out the hopper assembly 3 and remove the rectangular sheet to complete the edge sealing on one side. Then, place the rectangular sheet back onto the hopper assembly 3 and arrange it neatly to form material 4. At this point, it is necessary to ensure that the uncoated second surface 42 and third surface 43 are exposed. Then, use two clamping plates 32 to quickly clamp material 4, and the operator uses a roller brush to coat the uncoated second surface 42 and third surface 43. Then, repeat the above steps to complete the production of the product.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
