Description

Technical Field

[0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a spraying equipment and process for the surface of an aluminum baking pan. Background Art

[0002] Baking trays are generally used in conjunction with electric ovens, which can bring many conveniences to people. Baking trays provide protection for electric ovens to prevent food from dripping directly into the oven and causing pollution. At the same time, baking trays can help food get more evenly heated, avoid deformation, and improve cooking quality. In addition, using baking trays can better control cooking capacity, cook multiple foods at one time, and improve the utilization rate of electric ovens. It makes the cooking process more convenient, efficient and beautiful, and plays an irreplaceable and important role in modern life. Common baking tray materials include glass, stainless steel, ceramic, aluminum baking trays, etc. Glass baking trays can withstand high temperature cooking, but they are heavy and have poor thermal conductivity. Stainless steel baking trays are suitable for cooking larger portions of food, but stainless steel itself has poor thermal conductivity and often suffers from local overheating. Ceramic baking trays are easy to clean, but have lower mechanical strength than metal materials and are prone to cracks and breakage. The advantage of aluminum baking trays is that they have good thermal conductivity, can heat food quickly and evenly, and effectively shorten cooking time. In addition, aluminum baking trays are relatively light and easy to hold and move. With the advancement of technology, non-stick coatings are increasingly widely used in the cooking field, and aluminum baking trays have become the first choice for baking trays.

[0003] After a new aluminum baking pan is made, it is generally necessary to perform surface pretreatment to remove the oxide layer before spraying. In the prior art, a spray gun is mostly used to spray the surface of an aluminum baking pan. However, since an aluminum baking pan has four corners and each baking pan is different in size and depth, spraying with an ordinary spray gun will cause uneven spraying at the corners. Some manufacturers use special pressurized spray guns with corners, which makes tooling positioning more complicated and greatly increases costs. Some manufacturers use manual roller brushing after using the spray gun, which has high technical requirements for the operator and is inefficient. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be pointed out that the terms "upper", "lower", "left", "right", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0038] It should be understood that, in the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense.

[0039] See attached Figure 1 To Attachment Fig. 9 The present embodiment provides an aluminum baking pan surface spraying device, comprising an aluminum baking pan 100, a baking pan placement table assembly 200, a support table assembly 300, a motor mounting frame 400, a driving assembly 500, a main transmission shaft assembly 600, a slave transmission shaft assembly 700 and a roller assembly 800.

[0040] The aluminum baking tray 100 usually has several specifications, that is, the length and width dimensions are somewhat different, but most of the depth dimensions are the same. For aesthetics, the arc radius of the four corners of the aluminum baking tray 100 is relatively large. During spraying, the aluminum baking tray 100 is usually engaged in the baking tray bracket 260 of the baking tray placement table assembly 200.

[0041] The placing table assembly 200 is connected to the foundation, and the baking tray placing table assembly 200 also includes a track 210, a lifting assembly 220, a horizontal telescopic assembly 230, a placing table 240 and an adjusting mechanism 250. The track 210 is fixedly connected to the foundation, the lifting assembly 220 is located at the top of the track 210, and a slider corresponding to the track 210 is arranged at the bottom of the bottom plate assembly 221 of the lifting assembly 220. One end of the horizontal telescopic assembly 230 is fixedly connected to the bottom plate assembly 221 through a connecting block, and the other end of the horizontal telescopic assembly 230 is connected to the foundation through an L-shaped support plate. The sliding of the lifting assembly 220 on the track 210 is achieved by telescoping the horizontal telescopic assembly 230. The placing table 240 is located at the lifting assembly 220. The top of the component 220 is fixedly connected thereto, and the height of the placement table 240 is adjusted by lifting and lowering the lifting component 220. Adjustment mechanisms 250 are arranged around the placement table 240, and the baking tray bracket 260 is fixed to the center of the placement table 240 through the adjustment mechanism 250. Because the aluminum baking tray 100 has different outer dimensions, and there is a one-to-one correspondence between the baking tray bracket 260 and the aluminum baking tray, it is necessary to design the adjustment structure 250 to ensure that the baking tray bracket 260 is clamped. It is not difficult to understand that the adjustment mechanism 250 shown in the figure only illustrates a structural form. In actual production, there can be a variety of structural forms, and the purpose is to ensure that the baking tray bracket 260 is located at the center of the placement table 240.

[0042] The support platform assembly 300 is located on the top of the baking tray placement platform assembly 200; the support platform assembly 300 includes a support plate 310 and an auxiliary support plate assembly, and the two auxiliary support plate assemblies are symmetrically distributed on both sides of the support plate 310. The auxiliary support plate assembly is fixedly connected to the support plate 310, and the support plate 310 is fixedly connected by a support or a hanger (not shown in the figure, and the specific connection form to be adopted depends on the site conditions on site), and a first bearing seat assembly 320 is fixedly connected to the top center of the support plate 310, and a bearing (not shown in the figure) is arranged between the support plate 310 and the first bearing seat assembly 320.

[0043] The auxiliary support plate assembly includes a first mounting plate 330, a second mounting plate 340, an electric push rod assembly 350 and a second bearing seat assembly 360. The first mounting plate 330 is vertically connected to the support plate 310. The second mounting plate 340 is L-shaped. One end of the electric push rod assembly 350 is fixedly connected to the first mounting plate 330, and the other end is fixedly connected to the second mounting plate 340. The second bearing seat assembly 360 is fixedly connected to the second mounting plate 340, and a bearing (not shown in the figure) is arranged between the second bearing seat assembly 360 and the second mounting plate 340.

[0044] The motor mounting frame 400 is located at the top of the support platform assembly 300 and is fixedly connected thereto; the driving assembly 500 is located at the top of the support platform assembly 300, and the driving assembly 500 is connected to the motor mounting frame 400; the driving assembly 500 includes a motor 510 and a coupling 520, the motor 510 is usually a low-speed motor, the motor 510 is located at the top of the coupling 520, and the extended shaft of the motor 510 is fixedly connected to the coupling 520; the main body of the motor mounting frame 400 is a U-shaped structure, and folded edges are provided on both sides of the motor mounting frame 400. A through hole is opened at the top of the motor mounting frame 400, and the diameter of the through hole is larger than the maximum outer diameter of the coupling to ensure the operability of the inspection box during maintenance. The top plate of the motor mounting frame 400 is fixedly connected to the mounting flange of the motor 510, and the folded edges on both sides of the motor mounting frame 400 are fixedly connected to the support plate 310. Shock-absorbing materials are arranged between the top plate of the motor mounting frame 400 and the mounting flange of the motor 510, and between the folded edges on both sides of the motor mounting frame 400 and the support plate 310. The shaking of the motor 510 is reduced by the arrangement of the shock-absorbing materials.

[0045] The main transmission shaft assembly 600 is located at the bottom of the driving assembly 500 and is connected thereto, and the main transmission shaft assembly 600 passes through the support plate 310 of the support platform assembly 300; the main transmission shaft assembly 600 includes a main shaft 610, a main gear 620, a limiting plate 630, a pad 640, a key 650 and a fixing rod 660, the main shaft 610 is fixedly connected to the coupling 520, the main shaft 610 passes through the main gear 620 and the pad 640, the pad 640 is located at the top of the main gear 620, the limiting plate 630 is located at the top of the pad 640, and the key 650 and the fixing rod 660 are located inside the main gear 620.

[0046] A first threaded hole 613 is provided at one end of the main shaft 610 away from the coupling 520, and the specifications of the first threaded hole 613 are consistent with the specifications of the locking rod 660. A first groove 611 and a second groove 612 are also provided on the main shaft 610, and the specifications of the second groove 612 are consistent with the specifications of the limiting plate 630. A main gear mounting hole 621 is provided at the center of the main gear 620, and a third groove 622 is provided on one side of the main gear mounting hole 621. A key 650 is engaged between the first groove 611 and the third groove 622. A fourth groove 623 is provided at the bottom of the main gear 620, and a second threaded hole 624 is provided at the top of the main gear 620.

[0047] See attached Figure 5 To Attachment Figure 7 The key 650 can prevent the possibility of large relative rotation between the main shaft 610 and the main gear 620. The four shorter bolts are sequentially passed through the mounting hole of the backing plate 640 and the second threaded hole 624 and locked. Then, the two longer bolts are sequentially passed through the mounting hole of the limiting plate 630, the mounting hole of the backing plate 640 and the second threaded hole 624 and locked, thereby achieving the fastening of the main transmission shaft assembly 600. Then, the fixing rod 660 is screwed into the first threaded hole 613, further ensuring the fastening connection between the main shaft 610 and the main gear 620. When the size of the aluminum baking pan 100 changes, only the main gear 620 needs to be replaced. Usually, the number of teeth of the main gear 620 is adjusted while ensuring that the modulus of the main gear 620 remains unchanged.

[0048] There are two slave transmission shaft assemblies 700, and the slave transmission shaft assemblies 700 and the main transmission shaft assembly 600 are gear meshing transmission; the slave transmission shaft assembly 700 includes a driven shaft 710 and a driven gear 720, the driven shaft 710 passes through the driven gear 720 and is fixedly connected thereto, the end of the driven shaft 710 close to the roller assembly 800 is a stepped shaft, and the end of the driven shaft 710 close to the roller assembly is provided with a roller clamping section 711, and the roller clamping section 711 is provided with a third threaded hole 712, and the main gear 620 and the driven gear 720 are connected at the same time. Figure 1 The height direction shown is centered. Since the gear thickness of the main gear 620 is greater than the gear thickness of the driven gear 720, it is ensured that under extreme conditions, the main gear 620 and the driven gear 720 are in a meshing state. The modules of the main gear 620 and the driven gear 720 are equal. Usually, the number of teeth of the main gear 620 is smaller than that of the driven gear 720, which will cause the speed of the driven shaft 710 to be lower than the speed of the main shaft 610. Since the speed of the main shaft 610 is consistent with the speed of the low-speed motor, the low-speed motor and gear meshing transmission of the present invention further reduce the working speed, avoiding the use of a reducer. At the same time, the working stroke of the electric push rod assembly 350 is an integer multiple of the module of the main gear 620, that is, the difference between the two angular distances of the two specifications of the aluminum baking tray 100 is an integer multiple of the module of the main gear 620.

[0049] The transmission shaft assembly 700 passes through the roller assembly 800; the roller assembly 800 includes a roller 810 and a locking screw 820, a roller mounting hole 821 is provided at the center of the roller 810, a fifth groove 822 is provided at the end of the roller mounting hole 821 away from the roller clamping section 711, a chamfer 813 is provided at the outer circular end of the roller 810 away from the roller clamping section 711, and a handle is provided on the locking screw 820. When the roller 810 and the transmission shaft assembly 700 are completely fixed by the locking screw 820, the locking screw 820 is completely located inside the roller 810, and there is a gap a between the transmission shaft assembly 700 and the locking screw 820, which ensures that the roller assembly 800 will not move up and down during operation.

[0050] When the aluminum baking pan 100 is formed into a finished product after blanking and stamping, the finished product is put into a pickling tank for pickling after polishing and dust removal, and then washed and dried after pickling. The dried aluminum baking pan 100 is placed in the baking pan bracket 260, and the spray gun is driven by a mechanical arm to spray its surface. After the spraying treatment is completed, the baking pan placement table assembly 200 is raised, so that the two roller assemblies 800 are abutted against the two corners of the aluminum baking pan 100, and the driving assembly 500 is started to drive the main transmission shaft assembly 600 to rotate, and the two roller assemblies 800 are driven to rotate through gear transmission, so that the two corners of the aluminum baking pan 100 are evenly coated.

[0051] The present invention also provides a spraying process for an aluminum baking pan surface, the spraying process comprising the following steps:

[0052] S1, placing the newly manufactured aluminum baking tray 100 into a pickling tank for pickling to remove the oxide layer;

[0053] S2, after pickling, the surface of the baking tray needs to be thoroughly washed with water to remove the residual acid solution;

[0054] S3, placing the dried aluminum baking pan 100 in the baking pan bracket 260, and spraying the surface of the aluminum baking pan 100 with a spray gun driven by a mechanical arm;

[0055] S4, after the spraying treatment is completed, the spray gun is removed, the baking tray placement table assembly 200 is raised, the two roller assemblies 800 are brought into contact with the two corners of the aluminum baking tray 100, the driving assembly 500 is started to drive the main transmission shaft assembly 600 to rotate, and the two roller assemblies 800 are driven to rotate through the gear transmission, so that the two corners of the aluminum baking tray 100 are evenly coated;

[0056] S5, lowering the baking tray placement table assembly 200, and driving the placement table assembly 200 to move to the bottom of the other two corners of the aluminum baking tray 100 by extending the horizontal telescopic assembly 230;

[0057] S6, raising the baking tray placement table assembly 200, so that the two roller assemblies 800 abut against the other two corners of the aluminum baking tray 100, and evenly coating the other two corners of the aluminum baking tray 100;

[0058] S7, lowering the baking tray placement table assembly 200 to separate the aluminum baking tray 100 from the baking tray bracket 260, so that the aluminum baking tray 100 enters the next process.

[0059] It is easy to understand that after the S6 process is completed, there is no need to reset the baking tray placement table assembly 200 to the original position.
