A multi-station rotary baking mechanism

Abstract

This utility model discloses a multi-station rotary baking mechanism, relating to the technical field of ink baking devices. The multi-station rotary baking mechanism includes a rotating component, an adjusting component, and a conveying component. The rotating component includes multiple sets of sprockets at both ends and a first fixed plate. The sprockets on the sides are single, while the sprockets in the middle are two each. Adjacent sprockets are connected by a transmission chain, which is staggered. This solution solves the limitations of traditional ink baking devices, such as difficulty in adapting to products of different lengths and poor versatility. Furthermore, single-station baking devices can only process one product at a time, resulting in low production efficiency. In fixed-station baking, the product remains stationary, and only one side is baked, easily leading to uneven drying of the circumference ink, with one side not dried and the other discolored due to over-baking.

Description

Technical Field

[0001] This utility model relates to the technical field of ink baking equipment, specifically a multi-station rotary baking mechanism. Background Technology

[0002] In industrial production, many products require ink printing on their circumferential surfaces for marking, decoration, or functionalization. As the manufacturing industry moves towards higher efficiency and precision, increasingly higher demands are being placed on the drying quality and production efficiency of inks on the circumferential surfaces of products.

[0003] Traditional ink baking equipment has limitations. It is difficult to adapt to products of different lengths and has poor versatility. Secondly, single-station baking equipment can only process one product at a time, resulting in low production efficiency and difficulty in keeping up with the high-speed production pace of modern production lines. When baking at a fixed station, the product is stationary and only one side is baked, which can easily lead to uneven drying of the ink around the circumference, with one side not drying and the other side discoloring due to over-baking. Therefore, we propose a multi-station rotary baking mechanism to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-station rotary baking mechanism to solve the limitations of the traditional ink baking device mentioned in the background art, which is difficult to adapt to products of different lengths and has poor versatility. Secondly, the single-station baking device can only process a single product at a time, resulting in low production efficiency. When baking at a fixed station, the product is fixed and only one side is baked, which easily leads to uneven drying of the circumference ink, with one side not being dried and the other side changing color due to over-baking.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station rotary baking mechanism, comprising a rotating assembly, an adjusting assembly, and a conveying assembly. The rotating assembly includes multiple sets of sprockets and a first fixed plate disposed at both ends. The sprockets located on the sides are single, while the sprockets located in the middle are two in number. Adjacent sprockets are connected by a transmission chain, which is staggered. A baking rotary motor is installed at one end of the two sprockets on the same side facing away from each other. A transmission rod is installed at one end of the sprockets at both ends facing away from each other. A rotating roller is installed at the other end of the transmission rod through the first fixed plate. An auxiliary roller is rotatably connected to one side of the rotating roller through the first fixed plate. A limit frame is installed on the upper part between the rotating roller and the auxiliary roller through the first fixed plate. A limit plate is installed at one end of the two first fixed plates facing away from each other.

[0006] Preferably, the adjustment assembly includes second fixing plates disposed at both ends, a first L-shaped plate is installed at one end of the two second fixing plates facing each other, a variable pitch motor is installed at one end of the first L-shaped plate, a threaded rod is installed on the output shaft of the variable pitch motor, a nut seat is threadedly connected to the outer wall of the threaded rod, an adjustment plate is installed on the top of the nut seat, and the top of the adjustment plate is fixedly connected to the first fixing plate.

[0007] Preferably, adjusting slide rails are installed on both sides of the top of the second fixed plate, and adjusting sliders are slidably connected on the adjusting slide rails, with the adjusting sliders being fixedly connected to the adjusting plate.

[0008] Preferably, an ultraviolet lamp box is installed on the upper part of the rotating assembly, and an exhaust hood is installed on the top of the ultraviolet lamp box.

[0009] Preferably, the conveying assembly includes a mounting plate, a lifting plate, and a transverse plate disposed on both sides. A gear is mounted on one end of the mounting plate, and two gears are connected by a rigid conveyor belt. A lifting servo motor is mounted on the other end of one of the gears. A turntable is mounted through the output shaft of the lifting servo motor and passes through the mounting plate. A first guide rod is mounted on the lower part of the other end of the turntable. Lifting slide rails are mounted on both sides of the other end of the mounting plate. The mounting plate is slidably connected to the lifting plate through the lifting slide rails. A transverse groove is provided inside the lifting plate, and the first guide rod is movably mounted inside the transverse groove.

[0010] Preferably, a transverse slide rail is installed on the upper and lower parts of the other end of the lifting plate, and a transverse slider is slidably connected on the transverse slide rail. A transverse plate is slidably connected to the lifting plate through the transverse slider. A transverse servo motor is installed on one end of the mounting plate, and a second L-shaped plate is installed on the output shaft of the transverse servo motor. A second guide rod is installed on the other end of the second L-shaped plate. A guide plate is installed on one side of the transverse plate, and a vertical groove is provided inside the guide plate. The second guide rod is movably installed inside the vertical groove, and the transverse plates on both sides are fixedly connected.

[0011] Preferably, a placement plate is installed on the top of the transverse plate, and multiple sets of V-shaped grooves are evenly arranged on the top of the placement plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This utility model uses a lifting servo motor to drive the first guide rod to rotate eccentrically, and the guiding effect of the horizontal groove can make the lifting plate move up and down along the lifting slide rail. The horizontal servo motor drives the second guide rod to rotate eccentrically, and the guiding effect of the vertical groove can make the horizontal plate move left and right along the horizontal slide rail through the horizontal slider. Finally, the product on the placement plate is smoothly transported between the rotating roller and the auxiliary roller of the rotating component, realizing the automatic picking and placing and transferring of the product, which can reduce manual intervention and improve positioning accuracy and efficiency.

[0014] (2) The rotating roller is driven to rotate synchronously by the cooperation of the baking rotary motor, sprocket, transmission chain and transmission rod. The product is placed between the rotating roller and the auxiliary roller. Under the action of the friction of the rotating roller and the weight of the product itself, it can rotate with the rotating roller. This solves the problem that the single-station baking device can only process a single product at a time, resulting in low production efficiency. When baking at a fixed station, the product is fixed and only one side is baked, which easily leads to uneven drying of the circumferential ink, with one side not being dried and the other side changing color due to over-baking.

[0015] (3) The variable pitch motor, threaded rod and nut seat can drive the adjustment plate to slide along the adjustment slide rail through the adjustment slider, thereby changing the distance between the first fixed plates on both sides, that is, adjusting the distance between the rotating rollers to adapt to the placement requirements of products of different lengths, and achieve compatibility with products of different lengths. This solves the problem that traditional ink baking devices have limitations, are difficult to adapt to products of different lengths, and have poor versatility. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-6 This utility model provides an embodiment of a multi-station rotary baking mechanism, comprising a rotating assembly 1, an adjusting assembly 2, and a conveying assembly 3. The rotating assembly 1 includes multiple sets of sprockets 5 at both ends and a first fixed plate 8. The sprockets 5 on the sides are single, while those in the middle are two. Adjacent sprockets 5 are connected by transmission chains 6, which are staggered. A baking rotary motor 4 is mounted on one end of the two sprockets 5 on the same side facing away from each other. A transmission rod 7 is mounted on one end of the sprockets 5 facing away from each other. The other end of the transmission rod 7 passes through the first fixed plate 8 and is fitted with a rotating roller 9. An auxiliary roller 10 is rotatably connected to one side of the rotating roller 9 via the first fixed plate 8. A limit frame 11 is mounted on the upper part between the rotating roller 9 and the auxiliary roller 10 via the first fixed plate 8. A limit plate 12 is mounted on one end of the two first fixed plates 8 facing away from each other. (See also...) Figure 4 The adjusting assembly 2 includes second fixing plates 13 disposed at both ends. A first L-shaped plate 14 is mounted on one end of the two second fixing plates 13 facing each other. A variable-pitch motor 15 is mounted on one end of the first L-shaped plate 14. A threaded rod 16 is mounted on the output shaft of the variable-pitch motor 15. A nut seat 17 is threadedly connected to the outer wall of the threaded rod 16. An adjusting plate 18 is mounted on the top of the nut seat 17. The top of the adjusting plate 18 is fixedly connected to the first fixing plate 8. Please refer to [link / reference]. Figure 2Adjustable slide rails 19 are installed on both sides of the top of the second fixed plate 13. Adjustable sliders 20 are slidably connected to the adjustable slide rails 19, and the adjustable sliders 20 are fixedly connected to the adjusting plate 18. Please refer to Figure 1 The rotating assembly 1 has an ultraviolet lamp box 39 mounted on its upper part, and an exhaust hood 40 is mounted on top of the ultraviolet lamp box 39. In use, the product is first moved between the rotating roller 9 and the auxiliary roller 10 via the handling assembly 3. The baking rotary motor 4 is started, driving the sprockets 5 at both ends and in the middle to rotate synchronously via the transmission chain 6. The sprockets 5 drive the rotating roller 9 to rotate synchronously via the transmission rod 7. The product is placed between the rotating roller 9 and the auxiliary roller 10, and rotates along with the rotating roller 9 under the friction and its own weight. Simultaneously, the limiting frame 11 and the limiting plate 12 restrict product deviation, ensuring stable rotation. The limiting frame 11 prevents the product from shifting during rotation and detaching from the rotating roller 9, while the limiting plate 12 restricts the product's front-to-back position. The ultraviolet lamp box 39 at the top is then activated to heat the rotating product. Because the product rotates continuously in a circumferential direction, the ink can be evenly exposed to ultraviolet light, avoiding the problem of "one side not drying and the other side discoloring" caused by single-sided baking. Multiple sets of rotating rollers 9 form multiple workstations, allowing multiple products to be baked simultaneously, shortening the total baking time. The exhaust hood 40 on top can promptly discharge the waste gas or hot gas generated during the baking process, improving the working environment and preventing gas accumulation from affecting product quality or operational safety. Starting the variable-pitch motor 15 drives the threaded rod 16 to rotate, and the nut seat 17 moves along the threaded rod 16, causing the adjusting plate 18 to slide along the adjusting slide rail 19 via the adjusting slider 20. Through the fixed connection between the adjusting plate 18 and the first fixed plate 8, the distance between the two first fixed plates 8 can be changed, that is, the distance between the rotating rollers 9 can be adjusted to adapt to the placement requirements of products of different lengths, achieving compatibility with products of different lengths.

[0025] Please see Figure 5 and Figure 6The conveying assembly 3 includes a mounting plate 21, a lifting plate 27, and a transverse plate 35 disposed on both sides. A gear 22 is mounted on one end of the mounting plate 21. The two gears 22 are connected by a rigid conveyor belt 23. A lifting servo motor 24 is mounted on the other end of one of the gears 22. A turntable 25 is mounted through the output shaft of the lifting servo motor 24 and passes through the mounting plate 21. A first guide rod 26 is mounted on the lower part of the other end of the turntable 25. Lifting slide rails 29 are mounted on both sides of the other end of the mounting plate 21. The lifting plate 27 is slidably connected to the mounting plate 21 through the lifting slide rails 29. A transverse groove 28 is provided inside the lifting plate 27. The first guide rod 26 is movably mounted inside the transverse groove 28. When product lifting operations are required, the lifting servo motor 24 is activated. The lifting servo motor 24 and the rigid conveyor belt 23 drive the gears 22 on both sides to rotate synchronously, thereby rotating the turntable 25. This, in turn, causes the first guide rod 26 to rotate eccentrically. Guided by the transverse groove 28, the first guide rod 26 slides within the groove, simultaneously moving the lifting plate 27 up and down along the lifting rail 29. Through the connecting action of the transverse plate 35, the placement plate 38 is lifted to accommodate the product placement height. The top of the placement plate 38 has a V-shaped groove for product positioning.

[0026] Please see Figure 5 and Figure 6 A horizontal sliding rail 36 is installed on the upper and lower parts of the other end of the lifting plate 27. A horizontal sliding slider 37 is slidably connected to the horizontal sliding rail 36. A horizontal sliding plate 35 is slidably connected to the lifting plate 27 via the horizontal sliding slider 37. A horizontal servo motor 30 is installed on one end of the mounting plate 21. A second L-shaped plate 31 is installed on the output shaft of the horizontal servo motor 30. A second guide rod 32 is installed on the other end of the second L-shaped plate 31. A guide plate 33 is installed on one side of the horizontal sliding plate 35. A vertical groove 34 is provided inside the guide plate 33. The second guide rod 32 is movably installed inside the vertical groove 34. The horizontal sliding plates 35 on both sides are fixedly connected. Please refer to [link to relevant documentation]. Figure 5 A placement plate 38 is mounted on the top of the transverse plate 35, and multiple sets of V-shaped grooves are evenly arranged on the top of the placement plate 38. When the product needs to be transversely moved, the transverse servo motor 30 is started. The transverse servo motor 30 drives the second L-shaped plate 31 to rotate, which in turn drives the second guide rod 32 to rotate eccentrically. Through the guiding action of the vertical groove 34, the second guide rod 32 can slide within the vertical groove 34 of the guide plate 33, and at the same time, it can also drive the guide plate 33 to move left and right. This allows the transverse plate 35 to move left and right along the transverse slide rail 36 via the transverse slider 37. The two transverse plates 35 are fixedly connected to ensure synchronous movement, and finally the product on the placement plate 38 is smoothly transported between the rotating roller 9 and the auxiliary roller 10 of the rotating assembly 1.
