Description

Technical Field

[0001] This utility model relates to the technical field of sugar alcohol mixing machines, and in particular to a sugar alcohol mixing machine that is easy to add materials to. Background Technology

[0002] In the food, pharmaceutical, and chemical industries, the mixing and processing of sugar alcohols is a critical production step. Due to the strong hygroscopicity and electrostatic adsorption properties of sugar alcohol powders, they easily form hard lumps during storage, directly affecting the uniformity of feeding and the quality of subsequent mixing. As the first step in the operation of a mixer, the smoothness and pretreatment effect of the feeding process directly determine production efficiency and product quality. Therefore, developing a mixer that is adaptable to the characteristics of sugar alcohol materials and achieves efficient crushing and stable conveying, while facilitating feeding, has become an important requirement for solving the pain points of sugar alcohol processing and improving production continuity.

[0003] The feeding systems of existing sugar alcohol mixers mostly adopt single-function mechanical structures. The crushing stage often uses crushing roller sets with fixed spacing, which are driven by a motor to rotate in opposite directions, using the squeezing action between the rollers to break up agglomerates; the conveying stage generally uses ordinary screw conveyors, which rely on the rotation of continuous screw blades to push materials, and can only achieve basic material transfer and simple crushing.

[0004] However, existing crushing structures have shortcomings. Due to the fixed spacing between the crushing rollers and the lack of adaptive adjustment capability, when encountering large lumps with a particle size exceeding the roller spacing, the lumps are easily stuck between the two rollers and cannot pass through, causing the crushing process to suddenly stall. This stalling not only interrupts the feeding process but also causes motor overload or component wear due to excessive instantaneous load. In severe cases, it is necessary to stop the machine for cleaning, which significantly reduces the continuity and smoothness of the feeding process and affects the overall production efficiency. Therefore, a sugar alcohol mixer that facilitates feeding is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sugar alcohol mixer that facilitates feeding, aiming to improve the problem of feed blockage caused by the easy jamming of the existing crushing roller.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sugar alcohol mixer that facilitates feeding includes a mixing tank, a feeding component is provided on one side of the mixing tank, and a crushing component is provided above the feeding component;

[0008] The crushing assembly includes a crushing box. Fixed blocks are fixedly connected to both sides of the outer wall of the crushing box. The side walls of both fixed blocks are provided with symmetrically distributed sliding grooves. Crushing rollers are symmetrically distributed inside the crushing box. The outer walls of the crushing rollers are slidably connected to the inner walls of the sliding grooves. Slider blocks are provided at both ends of the crushing rollers. The outer walls of the sliders are slidably connected to the interiors of the fixed blocks. A bearing is fixedly connected to the center of the slider. Both ends of the crushing rollers are fixedly connected to the bearing. Limiting springs are symmetrically distributed on the side of the slider. One end of each limiting spring is fixedly connected to the interior of a fixed block, and the other end is fixedly connected to the side wall of the slider.

[0009] As a further description of the above technical solution:

[0010] A motor is symmetrically arranged on the side of one of the fixed blocks. The bottom of the motor is provided with a fixing plate. The side wall of the fixing plate is fixedly connected to the outer wall of the fixed block on one side. The bottom of the motor is slidably connected to the top of the fixing plate. The output end of the motor is fixedly connected to one end of the crushing roller.

[0011] As a further description of the above technical solution:

[0012] A fixing frame is fixedly connected to the outer wall of the mixing tank, and a discharge valve is fixedly connected to the center of the bottom of the mixing tank.

[0013] As a further description of the above technical solution:

[0014] A hopper is fixedly connected to the top of the crushing box, and a support frame is fixedly connected to the outer wall of the crushing box. The support frame is used to support the feeding assembly and the crushing assembly.

[0015] As a further description of the above technical solution:

[0016] The feeding assembly includes a feeding pipe, one end of which is fixedly connected to the outer wall of the top of the mixing tank.

[0017] As a further description of the above technical solution:

[0018] A connecting box is fixedly connected to one side of the top of the feed pipe, and the top of the connecting box is fixedly connected to the bottom of the crushing box.

[0019] As a further description of the above technical solution:

[0020] A second motor is fixedly connected to the side wall of the feed pipe, and a drive shaft is fixedly connected to the output end of the second motor. The drive shaft is located inside the feed pipe.

[0021] As a further description of the above technical solution:

[0022] A first conveyor blade is fixedly connected to the outer wall of the drive shaft near the connecting box. A second conveyor blade is provided on one side of the first conveyor blade. The second conveyor blade is fixedly connected to the outer wall of the drive shaft. The pitch of the second conveyor blade is smaller than that of the first conveyor blade.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a motor drives the crushing roller to rotate and crush the agglomerated raw materials. When encountering larger agglomerated materials, the outer wall of the agglomerated material squeezes the crushing roller to move, causing the sliders at both ends to slide within the fixed block and compress the limiting spring. After the agglomerated material is crushed, the thrust disappears, and the spring pushes the sliders to reset so that the roller returns to its original position. This achieves the effect of adaptively crushing agglomerated materials of different sizes, solves the problem of easy jamming of traditional crushing rollers leading to feed blockage, and improves the smoothness of feeding.

[0025] 2. In this utility model, the second motor drives the transmission shaft to rotate, which drives the first and second conveyor blades to operate synchronously and push the material displacement. At the same time, the pitch of the second conveyor blade at the end becomes smaller, which enhances the shearing and squeezing effect on the material, achieving the effect of fully mixing and conveying the material. This solves the problem of conveying jams during the feeding process in traditional methods and improves the uniformity of feeding and the premixing effect. Attached Figure Description

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.

[0034] Reference Figures 1-5 This utility model provides an embodiment of a sugar alcohol mixer that facilitates feeding, including a mixing tank 1. The mixing tank 1 is welded from 304 stainless steel and serves as a container for mixing raw materials. The mixing tank 1 is existing technology and will not be described in detail here. The fixing frame 2, which is welded from Q235B angle steel and is fixed to the outer wall by bolts, is used to support the mixing tank 1 and ensure the stability of the overall structure. The discharge valve 3, which is a stainless steel ball valve, is fixed to the center of the bottom of the mixing tank 1 by a flange and is used to control the discharge of the mixed material.

[0035] The crushing box 7 of the crushing assembly is welded from 304 stainless steel. The fixing blocks 10, bolted to both sides of the outer wall, are made of Q235B steel plate and are used to install the crushing roller 9 and sliding components. Symmetrically distributed sliding grooves 13 on the side walls of the fixing blocks 10 provide sliding tracks for the crushing roller 9. The symmetrically distributed crushing rollers 9 inside the crushing box 7 are made of high-chromium cast iron with a surface hardening treatment. Their outer walls slide against the inner walls of the sliding grooves 13 to crush agglomerated raw materials. The crushing roller 9 is existing technology and will not be described in detail here. The sliders 11 at both ends of the crushing roller 9 are made of aluminum alloy. Their outer walls have a clearance fit with the guide grooves inside the fixing blocks 10, and they slide within the fixing blocks 10 to support the crushing roller 9 and transmit displacement. The center position of the slider 11 is press-fitted. The bearing 12 is fixedly connected, and the two ends of the crushing roller 9 are fixedly connected to the bearing 12 by keys to realize the rotation of the crushing roller 9. The upper and lower symmetrically distributed limit springs 14 on the side of the slider 11 are made of spring steel. One end is welded to the spring seat inside the fixed block 10, and the other end is welded to the side wall of the slider 11 to provide the reset spring force for the slider 11, ensuring that the crushing roller 9 resets after adaptive adjustment. The left and right symmetrical motors 15 on the side of the fixed block 10 are three-phase asynchronous motors. Motors 15 are existing technology and will not be described in detail in this article. The bottom fixed plate 16 is welded from Q235B steel plate and is fixedly connected to the outer wall of the fixed block 10. The bottom of the motor 15 is slidably connected to the top of the fixed plate 16, and the output end is fixedly connected to one end of the crushing roller 9 by a coupling to drive the crushing roller 9 to rotate.

[0036] The hopper 6, which is bolted to the top of the crushing box 7, is made of stainless steel plate and is funnel-shaped. It is used to guide raw materials into the crushing box 7. The support frame 5, which is bolted to the outer wall of the crushing box 7, is made of H-beam steel and is used to support the feeding assembly and the crushing assembly to ensure the stability of the overall structure.

[0037] The feed pipe 4 of the feeding assembly is made of 304 stainless steel seamless steel pipe. One end is fixedly connected to the top outer wall of the mixing tank 1 through a flange for conveying crushed raw materials. The top side of the feed pipe 4 is fixedly connected to the connecting box 8, which is made of stainless steel plate. The top is fixedly connected to the bottom of the crushing box 7 for guiding the crushed raw materials into the feed pipe 4. The side wall of the feed pipe 4 is fixedly connected to the motor 17, which is also a three-phase asynchronous motor. The output end is fixedly connected to the drive shaft 18 through a coupling. The drive shaft 18 is made of stainless steel and is located inside the feed pipe 4 for transmitting power. The outer wall of the drive shaft 18 is fixedly connected to the conveying blade 19, which is made of stainless steel and is used for initial conveying of raw materials. The side of the conveying blade 19 is fixedly connected to the outer wall of the drive shaft 18 through welding. The blade spacing is smaller than that of the conveying blade 19 to enhance the material mixing effect and conveying pressure.

[0038] Working principle: When using this easy-to-feed sugar alcohol mixer, the raw materials and additives are first poured into the crushing box 7 through the hopper 6. At this time, the two motors 15 on one side of the crushing box 7 drive the crushing rollers 9 to rotate. The opposing rotation of the two crushing rollers 9 crushes the agglomerated raw materials. When encountering larger agglomerated raw materials, the agglomerated raw materials will generate an outward pushing force on the crushing rollers 9 on both sides. This pushing force pushes the crushing rollers 9 to move outward. The displacement of the crushing rollers 9 then drives the sliders 11 at both ends to slide outward inside the fixed block 10. The displacement of the sliders 11 also causes the limiting springs 14 to be compressed. When the agglomerated raw materials are crushed, the pushing force disappears, the limiting springs 14 push the sliders 11 to reset, and then the crushing rollers 9 on both sides return to their original positions. This achieves the effect of adaptively crushing agglomerated raw materials of different sizes.

[0039] The crushed raw materials flow into the feed pipe 4 through the connecting box 8. At this time, the motor 17 on one side of the feed pipe 4 drives the transmission shaft 18 to rotate. The rotation of the transmission shaft 18 drives the first conveyor blade 19 and the second conveyor blade 20 to rotate synchronously. The rotation of the first conveyor blade 19 and the second conveyor blade 20 has a preliminary mixing effect on the raw materials and additives, and also promotes the continuous displacement of the raw materials and additives into the mixing tank 1 inside the feed pipe 4. The small distance between the screw blades of the second conveyor blade 20 makes the movement space of the raw materials and additives in the feed pipe 4 more compact, and the shearing and squeezing effect of the screw blades on the materials is stronger. Finally, under the action of the first conveyor blade 19 and the second conveyor blade 20, the raw materials and additives are injected into the mixing tank 1, thereby achieving the effect of conveying and fully mixing the materials.

[0040] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
