Description

Technical Field

[0001] This utility model relates to the field of candy processing equipment technology, specifically a four-stage flattening machine adapted to candy strips of various thicknesses. Background Technology

[0002] A four-roll flattening machine is a piece of equipment used for processing sugar strips. It uses multiple sets of pressure rollers to calender the sugar strips, turning them into sugar strips of uniform thickness and continuous length.

[0003] In the prior art, the sugar strips extruded by the extruder fall onto the conveyor belt of the four-stage flattening machine. As the conveyor belt runs, the sugar strips are slowly transported between the pressure rollers and the conveyor belt. After being calendered by multiple sets of pressure rollers, the sugar strips are formed into a sugar strip with uniform thickness and continuous flow, which facilitates subsequent cutting and shaping processes.

[0004] However, most existing four-stage flattening machines are designed for sugar strips of a single thickness. When producing sugar strips of different thicknesses, it is necessary to change the pressure roller sets of different diameters. This process is time-consuming and labor-intensive, which may affect production efficiency and also results in poor equipment versatility, failing to meet the diverse needs of sugar strip production. Therefore, this invention proposes a four-stage flattening machine adapted to sugar strips of multiple thicknesses to effectively solve the aforementioned drawbacks. Utility Model Content

[0005] The purpose of this invention is to provide a four-pass flattening machine that is compatible with sugar strips of various thicknesses, in order to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: a four-stage flattening machine adapted to sugar strips of various thicknesses, including a conveying mechanism and several calendering mechanisms. The conveying mechanism is fixedly provided with a mounting frame assembly. The calendering mechanism includes two flattening rollers. The two flattening rollers are connected by a connecting assembly and are slidably mounted on the mounting frame assembly in a vertical direction. The conveying mechanism and the connecting assembly are jointly provided with a driving assembly. The driving assembly is used to drive the connecting assembly to move vertically to control the lifting and lowering of the flattening rollers.

[0007] Optionally, the mounting frame assembly includes four frames, which are symmetrically distributed in pairs on the left and right sides of the conveying mechanism. The frames extend vertically and are fixedly connected to the conveying mechanism. Two flattening rollers are slidably connected vertically between the four frames through a connecting assembly along the conveying direction of the conveying mechanism.

[0008] Optionally, the frame has a rectangular frame structure, and the connecting component includes a slider that is rotatably fitted on the end of the flattening roller. The slider is vertically slidably connected to the inside of the frame and is adapted to the shape of the inside of the frame. The two sliders located on the same side of the two flattening rollers are fixedly connected by a connecting plate. The connecting plate passes through the side wall of the frame and is vertically slidably connected to the side wall of the mounting frame assembly.

[0009] Optionally, the two connecting plates located on the left and right sides of the conveying mechanism are fixedly connected by a connecting frame, which is U-shaped, and the driving component is mounted on the connecting frame and used to drive the connecting frame to rise and fall.

[0010] Optionally, the drive assembly includes a U-shaped fixed frame, with the left and right side plates of the fixed frame fixedly connected to the left and right sides of the conveying mechanism. The connecting plate is located inside the fixed frame, and a plurality of positioning holes are provided on both the left and right side plates of the fixed frame. The plurality of positioning holes are distributed vertically, and the connecting plate is provided with mounting holes of the same diameter as the positioning holes. Bolts are inserted into both the positioning holes and the mounting holes to connect the fixed frame and the slider.

[0011] Optionally, a plate is fixed between the left and right side walls of the fixed frame, and the left and right side plates of the connecting frame penetrate the plate vertically and are slidably connected to the plate. A lead screw is rotatably connected to the plate, and the lead screw penetrates the top wall of the connecting frame vertically and is threadedly connected to the top wall of the connecting frame. The top end of the lead screw extends above the fixed frame and is fixedly connected to a drive handle.

[0012] Compared with the prior art, this utility model provides a four-stage flattening machine that is adaptable to sugar strips of various thicknesses, and has the following beneficial effects: 1. This utility model connects two flattening rollers together through a connecting component, and uses a driving component to drive the connecting component to move vertically on the mounting frame component, so that the connecting component can simultaneously drive the two flattening rollers to rise and fall. This not only makes it easier to adjust the distance between the flattening rollers and the conveyor belt, but also prevents different distances between the flattening rollers and the conveyor belt, avoiding insufficient or excessive calendering of the sugar strip during conveying, and improving the quality of the calendered sugar strip. 2. This utility model has mounting holes on the connecting plate and multiple positioning holes that match the mounting holes on the fixing frame. By inserting bolts into different positioning holes, the connecting components are fixed, thereby fixing the height of the flattening roller. This not only makes the height adjustment more precise, but also reinforces the installation of the connecting components with the lead screw, making the flattening roller more stable during use.

[0015] 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.

[0016] Please see Figure 1 - Figure 5 This application proposes a four-stage flattening machine adapted to sugar strips of various thicknesses, including a conveying mechanism 1 and several calendering mechanisms 2. The conveying mechanism 1 is fixedly provided with a mounting frame assembly 3. The calendering mechanism 2 includes two flattening rollers 201. The two flattening rollers 201 are connected by a connecting assembly 4 and are slidably mounted on the mounting frame assembly 3 in a vertical direction.

[0017] The conveying mechanism 1 includes a frame and a conveyor belt. The flattening roller 201 is located above the conveyor belt so that when the connecting component 4 slides vertically on the mounting frame component 3, it can drive the two flattening rollers 201 to rise and fall synchronously. This allows the flattening rollers 201 to adapt to the calendering operation of sugar strips of different thicknesses, and also prevents the two flattening rollers 201 from being one high and one low, thereby avoiding over-calendering or under-calendering of the sugar strip and improving the quality of the sugar strip.

[0018] Furthermore, the mounting frame assembly 3 includes four frame bodies 301, which are symmetrically distributed in pairs on the left and right sides of the conveying mechanism 1. The frame bodies 301 extend vertically and are fixedly connected to the conveying mechanism 1. Two flattening rollers 201 are slidably connected vertically between the four frame bodies 301 along the conveying direction of the conveying mechanism 1 via a connecting assembly 4. The frame bodies 301 are fixedly connected to the side of the machine frame by bolts, and the flattening rollers 201 are distributed along the conveying direction of the conveying mechanism 1, with their left and right ends slidably mounted on the frame bodies 301 via the connecting assembly 4.

[0019] Specifically, the frame 301 has a rectangular frame structure, and the connecting component 4 includes a slider 401 rotatably mounted on the end of the flattening roller 201. The slider 401 is vertically slidably connected to the inside of the frame 301 and is adapted to the shape of the inside of the frame 301. The end of the flattening roller 201 and the slider 401 are rotatably connected by a rotating bearing. A buffer pad is fixedly adhered to the side wall of the groove on the inside of the frame 301 for the slider 401 to slide, so as to increase the friction between the slider 401 and the frame 301, making the slider 401 more stable when sliding. At the same time, it also prevents the slider 401 from moving inside the frame 301 without the action of external force, so as to keep the flattening roller 201 stable.

[0020] On the other hand, the two sliders 401 located on the same side of the two flattening rollers 201 are fixedly connected by a connecting plate 402. The connecting plate 402 passes through the side wall of the frame 301 and is slidably connected to the side wall of the mounting frame assembly 3 in a vertical direction. This is so that when the connecting plate 402 moves vertically, it can simultaneously drive the two sliders 401 to rise and fall, thereby driving the two flattening rollers 201 to rise and fall synchronously.

[0021] like Figure 3 and Figure 4 As shown, the frame 301 encloses the slider 401 to prevent the slider 401 from detaching from the inner side of the frame 301. The side wall of the frame 301 has a vertical groove for sliding connection with the connecting plate 402. The width of this vertical groove is smaller than the width of the groove on the inner side of the mounting bracket assembly 3 for the slider 401 to slide in, so that the slider 401 does not tilt from the inner side of the mounting bracket assembly 3 towards the connecting plate 402.

[0022] Furthermore, the conveying mechanism 1 and the connecting assembly 4 are jointly provided with a driving assembly 5. The driving assembly 5 is used to drive the connecting assembly 4 to move vertically to control the lifting and lowering of the flattening roller 201. Specifically, the two connecting plates 402 located on the left and right sides of the conveying mechanism 1 are fixedly connected by a connecting frame 403. The connecting frame 403 is U-shaped. The driving assembly 5 is set on the connecting frame 403 and is used to drive the connecting frame 403 to lift and lower, so that when the driving assembly 5 drives the connecting frame 403 to lift and lower, the connecting frame 403 can drive the connecting plates 402 on both sides to lift and lower synchronously, thereby driving the sliders 401 on the connecting plates 402 to lift and lower synchronously, and then driving the flattening roller 201 to lift and lower synchronously.

[0023] In this embodiment, the drive assembly 5 includes a U-shaped fixed frame 501. The left and right side plates of the fixed frame 501 are fixedly connected to the left and right sides of the conveying mechanism 1. The connecting plate 402 and the connecting frame 403 are both located inside the fixed frame 501. A plurality of positioning holes 502 are provided on both the left and right side plates of the fixed frame 501, and these positioning holes 502 are distributed vertically. The connecting plate 402 has mounting holes 404 with the same diameter as the positioning holes 502. Bolts are inserted into both the positioning holes 502 and the mounting holes 404 to connect the fixed frame 501 and the slider 401. This allows the bolts to simultaneously position the height of the connecting plate 402 through the mounting holes 404 and the positioning holes 502, thereby simultaneously fixing the connecting plate 402 and fixing the height of the flattening roller 201. This prevents the flattening roller 201 from shaking during use and improves stability. By aligning the mounting hole 404 with the positioning holes 502 at different heights, the height of the flattening roller 201 can be changed, thus adapting the flattening roller 201 to the calendering of sugar strips of different thicknesses.

[0024] It should be noted that a separate mounting bracket (not shown in the attached diagram) is independently installed beside the flattening machine. A motor for driving the flattening roller 201 is fixedly mounted on this bracket. The motor's height and position are always fixed. A drive synchronous pulley is coaxially mounted on the motor's output shaft. The shaft end of the flattening roller 201 extends beyond the frame 301 and is fixedly mounted with a driven synchronous pulley. The drive and driven synchronous pulleys are connected by a synchronous belt, which is made of high-elasticity polyurethane, to enable the motor to drive the flattening roller 201. Simultaneously, an automatic tensioning pulley is installed on the slack side of the synchronous belt to adjust its tension according to the height of the flattening roller 201, ensuring the motor can always drive the flattening roller 201.

[0025] Furthermore, a plate 503 is fixedly provided between the left and right side walls of the fixed frame 501. The left and right side plates of the connecting frame 403 penetrate the plate 503 vertically and are slidably connected to the plate 503. A lead screw 504 is rotatably connected to the plate 503. The lead screw 504 penetrates the top wall of the connecting frame 403 vertically and is threadedly connected to the top wall of the connecting frame 403. The top end of the lead screw 504 extends above the fixed frame 501 and is fixedly connected to a drive handle 505.

[0026] The bottom end of the lead screw 504 and the top surface of the plate 503 are rotatably connected by a rotating bearing, and the lead screw 504 is rotatably connected to the top wall of the fixed frame 501. The lead screw 504 and the top wall of the connecting frame 403 are threaded together, and the friction between the lead screw 504 and the plate 503 can cooperate with the bolts at the positioning hole 502 to support the connecting assembly 4, thereby ensuring that the flattening roller 201 runs stably without shaking.

[0027] The working principle and usage process of this utility model are as follows: When it is necessary to adjust the height of the flattening roller 201, first remove the bolts at the connecting frame 403, then turn the drive handle 505, and drive the connecting frame 403 to rise and fall through the lead screw 504. The connecting frame 403 drives the slider 401 to rise and fall inside the mounting frame assembly 3 through the connecting plate 402. The slider 401 drives the flattening roller 201 to rise and fall to change the distance between the flattening roller 201 and the conveyor belt, so that the device can adapt to the calendering work of sugar belts of various thicknesses.
