Description

Technical Field

[0001] This invention belongs to the technical field of roller dryers, and particularly relates to a uniform flow single roller dryer. Background Technology

[0002] Potato flour retains the flavor of freshly steamed potatoes, with minimal nutrient loss, good quality stability, easy processing, and easy shaping. Therefore, it is widely used in compound fries, potato chips, instant mashed potatoes, fast food, puffed foods, and baby food, and is a popular ingredient in various international snack and health food products. Roller dryers are key production equipment. Existing roller dryers typically consist of one main roller and several auxiliary rollers. Raw materials are injected between the auxiliary rollers, ensuring even distribution on the main drying roller. As the main drying roller rotates, scrapers peel the raw materials off layer by layer, resulting in stable drying and extrusion molding. However, the scraping mechanism in this structure is usually fixed in position, meaning the dried raw materials can only be scraped in a single location. This causes the scraped material to accumulate in a specific area below the drying chamber, leading to adhesion. Therefore, the existing structure needs to be upgraded to ensure even distribution of the raw materials. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention provides a uniform flow single-roller dryer that can uniformly distribute raw materials and offers convenient and flexible driving.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A uniform flow single-roller dryer includes a drying chamber, a main drying roller, upper auxiliary rollers, a scraper guide plate, a rotating mechanism, and a transmission mechanism. The main drying roller is rotatably mounted inside the drying chamber. Upper auxiliary rollers are installed at both ends of the upper side of the main drying roller, forming a feeding zone between the two auxiliary rollers. The scraper guide plate is abutted against the side of the main drying roller. The rotating mechanism is installed inside the drying chamber and includes a supporting rotating column, a rotating convex ring, a transmission ring sleeve, and a moving plate. A supporting rotating column is installed at each of the front and rear ends of the main drying roller, and the outer end of the supporting rotating column is rotatably connected to the inner side wall of the drying chamber. The transmission ring is rotatably engaged with the supporting rotating column. A rotating convex ring is connected to the inner side of the transmission ring. The front and rear ends of the scraper guide plate are connected to the rotating convex ring. The lower side of the transmission ring abuts against a movable plate. The transmission mechanism is installed on one side of the drying chamber. The transmission mechanism controls the two movable plates to move horizontally and drives the scraper guide plate to abut against the side of the main drying roller and rotate circumferentially.

[0005] Furthermore, the supporting rotating column, rotating convex ring, transmission ring sleeve, and drying main roller are coaxially distributed.

[0006] Furthermore, the end of the movable plate is provided with a movable locking block; the interior of the drying chamber is provided with a movable locking groove; the movable locking block is slidably locked into the movable locking groove.

[0007] Furthermore, the movable plate and the transmission ring sleeve abut together in a meshing structure resembling a toothed plate and a gear.

[0008] Furthermore, the front and rear ends of the scraper guide plate are connected to the side of the rotating convex ring via transmission folding rods.

[0009] Furthermore, the transmission mechanism includes a transmission box, fixed rods, a linkage plate, a translation sleeve, a drive column, and a power motor; the transmission box is installed on the outside of one side of the drying chamber; the power motor is installed inside the transmission box; a fixed rod is installed on the outer end of each of the movable plates, and the ends of the two fixed rods are connected to a linkage plate; a translation sleeve is installed in the middle of the outer side of the linkage plate; the translation sleeve is slidably engaged with the drying chamber; a drive column is threaded to the inner side of the outer end of the translation sleeve, and the drive column is rotatably installed on the side wall of the drying chamber, with the outer end of the drive column extending into the transmission box; the power motor controls the rotational movement of the outer end of the drive column.

[0010] Furthermore, the outer end of the power motor is provided with a drive gear, and the outer end of the drive column is provided with a driven gear; the drive gear and the driven gear are connected and transmitted through a transmission chain.

[0011] Furthermore, the front and rear of the translation sleeve are respectively provided with limiting sliding posts; the front and rear of the drying chamber are respectively provided with limiting slots; the outer end of the limiting sliding post is slidably engaged with the limiting slot.

[0012] Furthermore, the upper end of the drying chamber is provided with a feeding pipe, which is located above the feeding section between the two upper auxiliary rollers.

[0013] The beneficial effects of this invention are as follows: This invention controls the rotation of a drive column via a power motor. The drive column drives a translation sleeve to move horizontally. The translation sleeve, through a linkage plate, drives a fixed rod to move horizontally, which in turn drives a moving plate to move horizontally. This moving plate then drives a transmission ring to rotate, which in turn drives a rotating convex ring to rotate. The rotating convex ring, through a transmission lever, drives a scraping guide plate to rotate circumferentially against the side of the drying main roller. This allows the scraping position of the scraping guide plate to be changed. Therefore, this invention allows for periodic adjustment of the scraping guide plate's position, ensuring that the scraped material is evenly distributed. The structure is flexible and convenient to use, eliminating the need for secondary adjustments that could cause further damage to the material. Attached Figure Description

The transmission mechanism 6 controls the two moving plates 54 to move horizontally and drives the scraper guide plate 4 to abut against the side of the main drying roller 2 and rotate circumferentially.

[0022] like Figures 1 to 6As shown, in order to stably control the rotation of the scraper guide plate 4, the supporting rotating column 51, the rotating convex ring 52, the transmission ring sleeve 53, and the drying main roller 2 are further coaxially distributed.

[0023] like Figures 1 to 6 As shown, in order to ensure the stable movement of the movable plate 54, the end of the movable plate 54 is provided with a movable locking block 541; the interior of the drying chamber 1 is provided with a movable locking groove 11; the movable locking block 541 is slidably locked into the movable locking groove 11.

[0024] like Figures 1 to 6 As shown, in order to facilitate the transmission connection between the moving plate 54 and the transmission ring sleeve 53, the moving plate 54 and the transmission ring sleeve 53 are further arranged in a meshing structure of toothed plates and gears.

[0025] like Figures 1 to 6 As shown, in order to facilitate the connection between the scraper guide plate 4 and the rotating convex ring 52, the front and rear ends of the scraper guide plate 4 are further connected to the side of the rotating convex ring 52 through the transmission folding rod 41.

[0026] like Figures 1 to 6 As shown, to facilitate the horizontal movement control of the two moving plates 54 by the transmission mechanism 6, the transmission mechanism 6 further includes a transmission box 61, a fixed rod 62, a linkage plate 63, a translation sleeve 64, a drive column 65, and a power motor 66.
