Description

Technical Field

[0001] This utility model relates to the field of tank production technology, specifically a tank recoating and drying device. Background Technology

[0002] Canned food is a type of packaged food made from sheet metal, glass, plastic, cardboard, or a combination of these materials. It is a sealable container used to store commercial food that has undergone specific treatment to achieve commercial sterility and can be kept at room temperature for a relatively long time without spoiling. After the roll is welded, the outer wall coating needs to be touched up with paint, so the can body needs to be recoated. In order to improve the processing speed, it needs to be dried after spraying.

[0003] Based on the above, the inventors have discovered the following problem: the current tank coating and drying device can only dry one tank body at a time in actual use, which is not convenient for drying multiple tank bodies at the same time, thus reducing the drying efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a tank coating and drying device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a tank coating and drying device to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A can body recoating and drying device includes a drying mechanism, a spraying assembly, a moving mechanism, and a placement mechanism. The spraying assembly is disposed on the outer side of the drying mechanism, the moving mechanism is disposed inside the drying mechanism, and the placement mechanism is disposed inside the moving mechanism. The drying mechanism is used to dry the can body after recoating, the spraying assembly is used to spray paint on the surface of the can body, the moving mechanism is used to drive the placement mechanism to move within the drying mechanism and the spraying assembly, and the placement mechanism is used to place the metal can to be sprayed and dried. The placement mechanism includes a placement frame, and movable seats are slidably provided on both sides of the inner side of the placement frame. Four circular grooves are opened on the opposite side of two of the movable seats. A turntable is rotatably connected inside each of the four circular grooves. Four rotating shafts are connected to one side of the inner wall of one of the movable seats through bearings. One end of each of the four rotating shafts passes through the circular groove and is fixedly connected to one side of the turntable.

[0008] Furthermore, each of the four rotating shafts is fitted with a worm gear, and the four worm gears are connected to a worm. A pair of fixed plates are installed at the bottom of the interior of one of the movable seats. The worm is positioned between the pair of fixed plates, and both ends of the worm are connected to one side of the pair of fixed plates via bearings. A second motor is installed on one side of the outer wall of one of the fixed plates, and the output end of the second motor is connected to the worm.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, during the spraying or drying process, through the coordinated use of the second motor, worm gear, and worm wheel, when the second motor is started, it drives the worm gear to rotate, which in turn drives the four worm wheels to rotate, thereby realizing the rotation of the four rotating shafts. This causes the turntables connected to the four rotating shafts to rotate. When the turntable in the circular groove of the left movable seat rotates, and the metal can is clamped between a pair of movable seats and located between a pair of turntables, the metal can can rotate during the spraying or drying process, ensuring uniform coating coverage, avoiding local over-thickness or missed coating, and improving drying efficiency. At the same time, the exterior of the four cans can be touched up or dried, improving the efficiency of touch-up coating and drying.

[0010] Furthermore, the front and back sides of the two movable seats are respectively provided with a first slide groove and a second slide groove. A slide bar is provided between the pair of first slide grooves and the pair of second slide grooves. The opposite sides of the two slide bars are fixedly connected to the inner walls of the placement frame. The outer walls of the two slide bars are slidably engaged with the inner walls of the first slide groove and the second slide groove. A pair of hydraulic rods are installed on the outer sides of the placement frame. The movable ends of the pair of hydraulic rods pass through the placement frame and are fixedly connected to the side of the movable seat away from the turntable.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting two pairs of hydraulic rods, the movable ends of the two pairs of hydraulic rods are fixedly connected to the opposite sides of the two movable seats. When the two pairs of hydraulic rods are activated, their movable ends extend outward to push the movable seats to move stably towards the center of the placement frame under the action of the slide bar, thereby adjusting the distance between a pair of movable seats and clamping and placing metal cans of different lengths.

[0012] Furthermore, the drying mechanism includes a bottom box, a top box is hinged to one side of the upper end of the bottom box, and openings are provided on one side of the top box and the bottom box. Mounting seats are installed at the bottom inside the bottom box and the top inside the top box, and several infrared lamps are installed on the opposite sides of the two mounting seats.

[0013] The beneficial effects of adopting the above-mentioned further solution are that by setting mounting seats at the upper inside of the top box and the lower inside of the bottom box, and installing infrared lamps on the opposite side of the two mounting seats, an annular radiation field is formed, which accelerates the curing of the coating on the surface of the tank and improves the drying efficiency. By opening openings on the left side of the top box and the bottom box, it is convenient for the placement rack and the moving seat to move from the inside of the spraying assembly to the inside of the drying mechanism for drying operations under the action of the moving mechanism.

[0014] Furthermore, the spraying assembly includes a spraying base, which is installed on one side of the outer wall of the base box, and a spraying head is installed at the upper inner end of the spraying base.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting up a spraying mechanism, the spraying head is vertically aligned with the surface of the tank, and the precise displacement of the moving mechanism enables targeted paint repair of local defects, reducing material waste.

[0016] Furthermore, the moving mechanism includes a fixed box, which is installed on one side of the inner wall of the base. A pair of frames are installed on the side of the fixed box away from the inner wall of the base. The ends of the pairs of frames away from the fixed box extend into the spraying seat. A lead screw is rotatably connected inside the pairs of frames. A slide block is threaded to the outside of the two lead screws. The outer walls of the two slide blocks are slidably engaged with the inner walls of the two frames, and the opposite sides of the two slide blocks are fixedly connected to the placement frame.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the lead screw, the square frame and the slide, when the lead screw rotates, the slide connected by its external thread achieves linear movement under the sliding engagement with the square frame. Since the slide is connected to the placement frame, the overall movement of the placement mechanism is realized, enabling it to move between the spraying assembly and the drying mechanism.

[0018] Furthermore, one end of each of the two lead screws extends through the fixed box into the interior and is fitted with a synchronous pulley. A synchronous belt is wound between the pair of synchronous pulleys. A first motor is installed on the outer wall of one of the frames, and the output end of the first motor is connected to one of the lead screws for transmission.

[0019] The beneficial effect of adopting the above-mentioned further solution is that by setting up a first motor, when the first motor is started, it is easy to drive one of the lead screws to rotate, and the other lead screw is rotated under the action of the synchronous pulley and the synchronous belt.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This can body recoating and drying device first activates two pairs of hydraulic rods. The movable ends of the two pairs of hydraulic rods are fixedly connected to the opposite sides of two movable seats. When the two pairs of hydraulic rods are activated, their movable ends extend outward, pushing the movable seats to move stably towards the center of the placement frame under the action of the slide bars, thereby adjusting the distance between a pair of movable seats. Four cans to be sprayed with paint are then sequentially clamped and placed between the movable seats, with the metal cans positioned between a pair of turntables. The second motor is then activated, driving the worm gear to rotate. The worm gear drives four worm wheels to rotate, thereby achieving the rotation of four rotating shafts, thus allowing the four cans to rotate. The turntable connected by the rotating shaft rotates. When the turntable in the circular groove of the left moving seat rotates, the metal can can be rotated under the clamping connection, which facilitates the simultaneous coating or drying of the exterior of four cans, improving the coating and drying efficiency. When the placement mechanism is located in the spraying assembly, the spraying head is vertically aligned with the can surface. The placement mechanism is driven to move by the moving mechanism to achieve targeted paint repair of local defects, reducing material waste. When the placement mechanism enters the drying mechanism through the opening under the action of the moving mechanism, infrared lamps are installed on the opposite side of the two mounting seats to form a ring radiation field, which accelerates the curing of the coating on the can surface and improves the drying efficiency.

[0028] Please see Figures 1-5 This utility model provides a technical solution: a can body recoating and drying device, including a drying mechanism 1, a spraying component 2, a moving mechanism 3, and a placing mechanism 4. The spraying component 2 is disposed on the outer side of the drying mechanism 1, the moving mechanism 3 is disposed inside the drying mechanism 1, and the placing mechanism 4 is disposed inside the moving mechanism 3. The drying mechanism 1 is used to dry the can body after recoating, the spraying component 2 is used to apply recoating paint to the surface of the can body, the moving mechanism 3 is used to drive the placing mechanism 4 to move within the drying mechanism 1 and the spraying component 2, and the placing mechanism 4 is used to place the metal can to be sprayed and dried. The placing mechanism 4 includes a placing frame 41, and movable seats 43 are slidably provided on both sides of the interior of the placing frame 41. Each of the two movable seats 43 has four circular slots on its opposite side. A turntable 45 is rotatably connected inside each of the four circular slots. One side of the inner wall of one of the movable seats 43 is connected to four rotating shafts 46 via bearings. One end of each of the four rotating shafts 46 passes through a circular slot and is fixedly connected to one side of the turntable 45. When the four rotating shafts 46 rotate, the turntable 45 connected to the four rotating shafts 46 rotates. When the turntable 45 in the circular slot of the left movable seat 43 rotates, the metal can is clamped between the pair of movable seats 43 and the metal can is located between the pair of turntables 45. This allows the metal can to rotate during the spraying or drying process, ensuring uniform coating coverage, avoiding localized over-thickness or missed coating, and improving drying efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 This utility model provides a technical solution: Worm gears 47 are fitted around the exterior of four rotating shafts 46, and worm gears 47 are connected to worms 49 via transmission. A pair of fixed plates 48 are installed at the bottom interior of one of the movable seats 43. The worm 49 is positioned between the pair of fixed plates 48, and both ends of the worm 49 are connected to one side of the pair of fixed plates 48 via bearings. A second motor 410 is installed on one side of the outer wall of one of the fixed plates 48, and the output end of the second motor 410 is connected to the worm 49 via transmission. First and second sliding grooves are respectively formed on the front and back of the two movable seats 43. Sliding strips 42 are provided between the pair of first and second sliding grooves. The opposing sides of the two sliding strips 42 are fixedly connected to both sides of the inner wall of the placement frame 41, and the outer walls of the two sliding strips 42 slide in cooperation with the inner walls of the first and second sliding grooves. A pair of hydraulic rods 44 are installed on both sides of the outer exterior of the placement frame 41. The movable ends of a pair of hydraulic rods 44 both pass through the placement frame 41 and are fixedly connected to the side of the movable seat 43 away from the turntable 45. When the two pairs of hydraulic rods 44 are activated, their movable ends are fixedly connected to the opposite sides of the two movable seats 43. When the two pairs of hydraulic rods 44 are activated, their movable ends extend outward, pushing the movable seat 43 to move stably toward the center of the placement frame 41 under the action of the slide bar 42, thereby adjusting the distance between the pair of movable seats 43. The four cans to be sprayed with paint are clamped and placed between the movable seats 43 in sequence, with the metal cans located between the pair of turntables 45. The second motor 410 is activated, which drives the worm gear 49 to rotate. The worm gear 49 drives the four worm wheels 47 to rotate, thereby realizing the rotation of the four rotating shafts 46, which in turn causes the turntables 45 connected to the four rotating shafts 46 to rotate. When the turntable 45 in the circular groove of the left movable seat 43 rotates, the metal cans can rotate under the clamping connection.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-5This utility model provides a technical solution: the drying mechanism 1 includes a bottom box 11, a top box 12 is hinged to one side of the upper end of the bottom box 11, and openings are provided on one side of both the top box 12 and the bottom box 11. Mounting seats 13 are installed at the bottom inside the bottom box 11 and the upper inside the top box 12. Several infrared lamps 14 are installed on opposite sides of the two mounting seats 13. The spraying assembly 2 includes a spraying seat 21, which is installed on one side of the outer wall of the bottom box 11, and a spraying head 22 is installed at the upper inside of the spraying seat 21. The moving mechanism 3 includes a fixed box 31. The fixing box 31 is installed on one side of the inner wall of the base. A pair of frames 32 are installed on the side of the fixing box 31 away from the inner wall of the base. The ends of the pairs of frames 32 away from the fixing box 31 extend into the spraying base 21. A lead screw 33 is rotatably connected to the inside of each pair of frames 32. A slide 34 is threaded to the outside of each lead screw 33. The outer walls of the two slides 34 slide in contact with the inner walls of the two frames 32, and the opposite sides of the two slides 34 are fixedly connected to the placement rack 41. One end of each lead screw 33 extends through the fixing box 31. Inside, each component is fitted with a synchronous pulley 35, and a synchronous belt 36 is wound between a pair of synchronous pulleys 35. A first motor 37 is installed on the outer wall of one of the square frames 32. The output end of the first motor 37 is connected to one of the lead screws 33. When the placement mechanism 4 is located inside the spraying assembly 2, the spraying head 22 is vertically aligned with the surface of the tank. By starting the first motor 37, one of the lead screws 33 can be driven to rotate, and the other lead screw 33 is rotated under the action of the synchronous pulleys 35 and the synchronous belt 36. The lead screw 33 is externally threaded to a sliding seat. 34 achieves linear movement under the sliding engagement with the frame 32. Since the slide 34 is connected to the placement frame 41, the overall movement of the placement mechanism 4 is realized, enabling it to move between the spraying assembly 2 and the drying mechanism 1. When the placement mechanism 4 is displaced, it can achieve point-to-point paint repair for local defects, reducing material waste. When the placement mechanism 4 enters the drying mechanism 1 through the opening under the action of the moving mechanism 3, infrared lamps 14 are installed on the opposite side of the two mounting seats 13 to form a ring radiation field, which accelerates the curing of the coating on the surface of the tank and improves the drying efficiency.

[0033] Specifically, the working principle of this can repair and drying device is as follows: During use, two pairs of hydraulic rods 44 are activated. The movable ends of the two pairs of hydraulic rods 44 are fixedly connected to the opposite sides of two movable seats 43. When the two pairs of hydraulic rods 44 are activated, their movable ends extend outward, pushing the movable seats 43 to move stably towards the center of the placement frame 41 under the action of the slide bar 42. This adjusts the distance between the pair of movable seats 43, allowing four cans to be sprayed with paint to be placed between the movable seats 43 in sequence, with the metal cans positioned between a pair of turntables 45. The second motor 410 is then activated, driving the worm gear 49 to rotate. The worm gear 49 drives four worm wheels 47 to rotate, thereby rotating the four rotating shafts 46. This causes the turntables 45 connected to the four rotating shafts 46 to rotate. When the turntable 45 in the circular groove of the left movable seat 43 rotates, the metal cans can rotate under the clamping connection. When the placement mechanism 4 is located inside the spraying assembly 2, the spraying head 22 is vertically aligned with the surface of the tank. The first motor 37 is started to drive one of the lead screws 33 to rotate, and the other lead screw 33 is rotated under the action of the synchronous pulley 35 and the synchronous belt 36. The slide 34 connected to the external thread of the lead screw 33 moves linearly under the sliding cooperation with the frame 32. Since the slide 34 is connected to the placement frame 41, the entire placement mechanism 4 can move, allowing it to move between the spraying assembly 2 and the drying mechanism 1. When the placement mechanism 4 is displaced, it can perform spot painting of local defects, reducing material waste. When the placement mechanism 4 enters the drying mechanism 1 through the opening under the action of the moving mechanism 3, infrared lamps 14 are installed on the opposite side of the two mounting seats 13 to form a ring radiation field, which accelerates the curing of the coating on the surface of the tank and improves the drying efficiency.
