Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to a cutting device for a vacuum belt dryer. Background Technology

[0002] A vacuum belt dryer is a continuous feeding and discharging contact vacuum drying device. The liquid material to be dried enters the high-vacuum dryer directly through a conveyor mechanism, spreading onto several drying belts inside the dryer. A motor-driven special rubber roller moves the drying belts at a set speed along the dryer cylinder. Each drying belt has three independent heating plates and one cooling plate underneath, with the drying belts in close contact with the heating and cooling plates, transferring the energy required for drying to the material through contact heat transfer. When the drying belt moves from one end of the cylinder to the other, the material has been dried and cooled. When the drying belt folds back, the dried material cake is peeled off the drying belt and dropped into a crushing device via a vertically moving cutting device. The crushed material is then discharged through two air-lock-type discharge hoppers.

[0003] When cutting sticky materials, the cutting device used in vacuum belt dryers tends to have material sticking to the blade surface, causing material accumulation. This prevents subsequent cutting from effectively contacting the material cake and may even block the gap between the conveyor belt and the cutter, requiring machine shutdown for cleaning and thus reducing work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a cutting device for a vacuum belt dryer, which aims to improve the problem that the cutting surface of the cutting device is prone to sticking to the material when cutting sticky materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for a vacuum belt dryer, comprising a support frame, with transmission rollers rotatably connected to both ends of the support frame, the toothed ends of the transmission rollers meshing with a conveyor belt, a motor fixedly connected to one end of the support frame, multiple electric push rods mounted on the top of the support frame, a fixed frame fixedly connected to the bottom ends of two of the electric push rods, multiple springs II provided on the outer wall of the fixed frame, a blade fixedly connected to the inner wall of the fixed frame, movable frames slidably connected to the inner walls of both sides of the fixed frame, two cleaning frames slidably connected to the inner walls of the two movable frames, two springs I provided on the inner walls of the movable frames, and a cleaning assembly provided at the bottom end of the support frame.

[0006] The above technical solution involves a motor driving a transmission roller to rotate, which in turn allows a conveyor belt to move materials. Two electric push rods then drive the blades up and down via a fixed frame, enabling the blades to cut the materials. Meanwhile, two cleaning frames, through the elastic force of springs one and two, clean the outer wall of the blades, achieving the effect of conveniently cleaning debris from the outer wall of the blades.

[0007] Preferably, the cleaning assembly includes a first synchronous pulley, which is fixedly connected to the output end of the motor. The teeth of the first synchronous pulley are engaged with a synchronous belt. A rotating rod is rotatably connected to the bottom end of the bracket. A cleaning component is fixedly connected to the outer wall of the rotating rod. A second synchronous pulley is fixedly connected to one end of the rotating rod.

[0008] Preferably, the timing pulley is meshed with the tooth end of the timing belt, and the cleaning component is rotatably connected to the outer wall of the conveyor belt.

[0009] Preferably, a collection box is installed at the bottom of the bracket, and the collection box is installed below the cleaning component.

[0010] Preferably, a collection box is fixedly connected to one end of the bracket, and the fixing frame is slidably connected to the top of the bracket.

[0011] Preferably, the conveyor belt is slidably connected to the top of the support, and the blade is slidably connected to the top of the conveyor belt.

[0012] Preferably, two of the springs are disposed on both sides of the cleaning frame, and the two cleaning frames are slidably connected to the outer wall of the blade.

[0013] Preferably, two of the springs are disposed at the top of the movable frame, and a plurality of the springs are disposed at the top of the cleaning frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, two springs are respectively set on the inner walls of the two cleaning frames and the moving frame, so that the two cleaning frames are always attached to the outer wall of the blade. At the same time, the elastic force of multiple springs allows the cleaning frames to clean the outer wall of the blade after the blade cuts the material.

[0016] 2. In this utility model, a synchronous belt meshes with synchronous pulley one and synchronous pulley two. Synchronous pulley one is fixed at the output end of the motor, and synchronous pulley two is fixed at one end of the rotating rod. When the motor is started and drives the conveyor belt to move, it indirectly drives the cleaning component to rotate, so that the cleaning component can clean the debris on the conveyor belt.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-5 This utility model provides an embodiment of a cutting device for a vacuum belt dryer, comprising a support 1, with transmission rollers 2 rotatably connected to both ends of the support 1, the toothed ends of the transmission rollers 2 meshing with a conveyor belt 3, a motor 4 fixedly connected to one end of the support 1, multiple electric push rods 5 mounted on the top of the support 1, a fixed frame 6 fixedly connected to the bottom ends of two electric push rods 5, multiple springs 11 provided on the outer wall of the fixed frame 6, a blade 7 fixedly connected to the inner wall of the fixed frame 6, movable frames 8 slidably connected to the inner walls of both sides of the fixed frame 6, two cleaning frames 9 slidably connected to the inner walls of the two movable frames 8, two springs 10 provided on the inner walls of the movable frames 8, a cleaning assembly provided at the bottom of the support 1, a collection box 12 fixedly connected to one end of the support 1, the fixed frame 6 slidably connected to the top of the support 1, the conveyor belt 3 slidably connected to the top of the support 1, and the blade 7 slidably connected to the top of the conveyor belt 3.

[0026] Specifically, by installing two electric push rods 5 on the top of both sides of the bracket 1, and connecting their bottom ends to the top of both sides of the fixed frame 6, two cleaning frames 9 can move on the inner wall of the fixed frame 6 through two movable frames 8. Then, multiple springs 11 are set between the movable frames 8 and the cleaning frames 9 and the fixed frame 6. When the blade 7 cuts the material through the fixed frame 6 and the electric push rods 5, the two cleaning frames 9 are placed on the material. When the blade 7 rises, the cleaning frames 9 move downward together through the elastic force of the springs 11, so that the cleaning frames 9 can clean the outer wall of the blade 7. At the same time, the collection box 12 can collect the cut material.

[0027] Reference Figures 1-3 The cleaning assembly includes a first synchronous pulley 13, which is fixedly connected to the output end of the motor 4. The teeth of the first synchronous pulley 13 are meshed with the synchronous belt 14. The bottom end of the bracket 1 is rotatably connected to a rotating rod 15. The outer wall of the rotating rod 15 is fixedly connected to a cleaning component 16. One end of the rotating rod 15 is fixedly connected to a second synchronous pulley 17, which is meshed with the teeth of the synchronous belt 14. The cleaning component 16 is rotatably connected to the outer wall of the conveyor belt 3. A collection box is installed at the bottom end of the bracket 1, and the collection box is installed below the cleaning component 16.

[0028] Specifically, the cleaning component 16 is fixedly connected to the outer wall of the rotating rod 15, allowing the rotating rod 15 to rotate and connect to the bottom end of the bracket 1, so that the cleaning component 16 contacts the first synchronous pulley 13. The first synchronous pulley 13 is fixedly connected to the output end of the motor 4, and the second synchronous pulley 17 is fixedly connected to the other end of the rotating rod 15, so that the first synchronous pulley 13 and the second synchronous pulley 17 mesh with the synchronous belt 14, allowing the motor 4 to indirectly drive the rotating rod 15 and the cleaning component 16 to rotate, so that the cleaning component 16 can clean the debris on the conveyor belt 3, and the collection box can collect the debris, achieving the effect of convenient cleaning of the conveyor belt 3.

[0029] Reference Figure 4 and Figure 5 Two springs 10 are located on both sides of the cleaning frame 9, and the two cleaning frames 9 are slidably connected to the outer wall of the blade 7. Two springs 21 are located at the top of the movable frame 8, and multiple springs 211 are located at the top of the cleaning frame 9.

[0030] Specifically, the two ends of the cleaning frame 9 are slid onto the inner walls of the two movable frames 8 respectively, and the spring 10 is placed between the cleaning frame 9 and the movable frames 8. The cleaning frame 9 can be pressed tightly against the outer wall of the blade 7 by the elastic force of the spring 10. At the same time, the two cleaning frames 9 are pressed tightly against the bottom of the blade 7 by the two movable frames 8 and multiple springs 211, so as to facilitate the cleaning frame 9 to clean the outer wall of the blade 7.

[0031] Working principle: Start motor 4, which drives conveyor belt 3 through transmission roller 2. When material is placed on conveyor belt 3, the material moves to the area below blade 7 through conveyor belt 3. Blade 7 cuts the material through electric push rod 5 and fixed frame 6. When blade 7 moves upward after cutting the material, the two cleaning frames 9 clean the outer wall of blade 7 through the elastic force of spring 10 and spring 21.

[0032] The cut material falls into the collection box 12 via the conveyor belt 3. At the same time, the motor 4 drives the rotating rod 15 and the cleaning component 16 to rotate via the synchronous pulley 13, the synchronous belt 14 and the synchronous pulley 17, so that the cleaning component 16 can clean the conveyor belt 3.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
