Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, specifically to a waste crushing device for toothpaste production. Background Technology

[0002] During toothpaste production, a large amount of substandard paste or scrap material is generated due to factors such as filling precision control, packaging losses, and equipment debugging. This waste material typically possesses a certain degree of stickiness and toughness; direct disposal not only wastes raw materials but also pollutes the environment. Therefore, recycling and reusing this waste is a crucial step for modern toothpaste manufacturers to reduce costs, increase efficiency, and achieve green production. Currently, the industry commonly uses mechanical pulverizing equipment to process the recycled toothpaste waste, bringing it back to a particle size standard suitable for production.

[0003] However, existing toothpaste waste recycling and shredding devices still have some technical problems that urgently need to be solved in actual use:

[0004] 1. Insufficient pulverization effect, making it difficult to achieve the desired fineness. Some existing devices only use a single-stage pulverization structure, that is, one-time crushing through one or two grinding wheels. Due to the special rheological properties of toothpaste waste, it is prone to clumping under pressure and may rebound under shear force. As a result, one-time pulverization often fails to completely destroy its original molecular chain structure and large block shape. The pulverized material particles are uneven in size and contain a lot of large pieces, which cannot meet the uniformity requirements of raw material particle size in subsequent mixing processes, thus affecting the quality stability of recycled toothpaste.

[0005] 2. Qualified materials are easily over-crushed, resulting in energy waste and material overheating. Existing crushing equipment lacks a precise grading and screening mechanism. After crushing, qualified materials that meet particle size requirements are mixed with those that do not. In pursuit of a higher pass rate, operators often extend the crushing time or increase the crushing intensity, causing those already qualified fine particles to be continuously subjected to grinding and shearing actions inside the machine. This "over-crushing" phenomenon not only increases unnecessary energy consumption but may also cause certain heat-sensitive ingredients in toothpaste to deteriorate due to frictional heat, further reducing the quality of the recycled materials.

[0006] Therefore, in view of this, the existing structure was studied and improved, and a waste recycling and crushing device for toothpaste production was proposed. Summary of the Invention

[0007] The technical problem this invention aims to solve is that the pulverizing effect is poor, it is difficult to achieve the ideal fineness, qualified materials are easily pulverized repeatedly, resulting in energy waste and material overheating.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a waste recycling and crushing device for toothpaste production, including a crushing box, a crushing component 1 is provided inside the crushing box, the crushing box is composed of a primary crushing box and a secondary crushing box, an inlet is fixedly provided through the top of the primary crushing box, an outlet is provided at the bottom of the primary crushing box, an outlet is provided on one side of the primary crushing box, a collection box connected to the outlet is fixedly provided through one side of the primary crushing box, a collection drawer 1 is slidably passed through the collection box, a cylindrical crushing chamber is provided near the top of the secondary crushing box, and the crushing chamber is connected through the outlet, a number of sieve holes are provided at the bottom of the crushing chamber, a collection drawer 2 is slidably passed through the secondary crushing box and located below the crushing chamber, and a number of support legs are fixedly provided at the bottom of the primary crushing box;

[0009] The first crushing component is installed in the first-stage crushing chamber. Inside the first-stage crushing chamber, below the first crushing component, a screening component is installed. The screening component screens out the qualified toothpaste waste and discharges it from the outlet. The screening component guides the unqualified toothpaste waste to the outlet and then into the second-stage crushing chamber for further crushing.

[0010] The crushing chamber is equipped with a second crushing component.

[0011] As a further embodiment of this utility model: the bottom of the primary crushing chamber is inclined and has a guide outlet.

[0012] As a further embodiment of this utility model: the crushing component includes two crushing wheels rotatably disposed inside the primary crushing chamber, and two mutually meshing gears are rotatably disposed on one side of the exterior of the primary crushing chamber, and the gears drive the corresponding crushing wheels to rotate, and a motor is fixedly disposed on the other side of the exterior of the primary crushing chamber to drive one of the crushing wheels to rotate.

[0013] As a further embodiment of this utility model: an inclined guide plate is provided inside the primary crushing chamber and between the crushing component and the screening component. The guide plate guides the toothpaste waste crushed by the crushing wheel to the screening component.

[0014] As a further embodiment of this utility model: the screening assembly includes a screen plate and a guide plate II, which are slidably and limitly disposed within the primary crushing chamber. The screen plate and the guide plate II are arranged in an inclined and staggered manner. One side of the screen plate and the guide plate II is fixedly connected, and the other side of the guide plate II is movably disposed at the discharge port. A receiving plate is fixedly disposed within the primary crushing chamber. Two springs are fixedly disposed between the receiving plate and the screen plate. An elliptical wheel is rotatably disposed on one side of the primary crushing chamber, and the elliptical wheel pushes the screen plate. A motor II that drives the elliptical wheel to rotate is fixedly disposed on one side of the primary crushing chamber.

[0015] As a further embodiment of this utility model: the second crushing component includes a crushing rod rotatably disposed inside the crushing chamber, a plurality of crushing blades fixedly disposed around the crushing rod, and a third motor for driving the crushing rod to rotate fixedly disposed on the outside of the secondary crushing chamber.

[0016] As a further embodiment of this utility model: the sieve holes sieve the qualified toothpaste waste pulverized by the pulverizing component two into the collection drawer two.

[0017] As a further embodiment of this utility model, a rubber pad is fixedly provided at the bottom of the support leg.

[0018] Compared with the prior art, the advantages of this utility model are as follows:

[0019] 1. This utility model adopts a two-stage crushing structure of "primary coarse crushing + secondary fine crushing". The crushing wheel (crushing component one) in the primary crushing chamber first performs preliminary crushing of large pieces of toothpaste waste; subsequently, the screening component can separate qualified materials that meet the particle size requirements in real time and quickly discharge them. This design ensures that only larger particles that do not meet the standards enter the secondary crushing chamber. Through this graded treatment method, the defects of incomplete traditional single-stage crushing are overcome, resulting in finer and more uniform waste particles that fully meet the requirements of reprocessing.

[0020] 2. This invention, through precise screening by the screening component, promptly discharges and collects qualified materials from the outlet, preventing them from participating in subsequent crushing processes. This fundamentally solves the problem of "qualified materials being repeatedly crushed" in existing devices. On the one hand, it reduces ineffective crushing operations, significantly lowering the equipment's operating energy consumption, aligning with the green production concept of energy conservation and emission reduction; on the other hand, it avoids the high temperatures generated by prolonged high-speed friction of materials within the crushing chamber, effectively preventing toothpaste waste from undergoing compositional denaturation or changes in properties due to overheating, thus ensuring the quality of the recycled materials.

[0021] The screening assembly employs a linked structure combining a screen plate, guide plate II, and elliptical wheels. Motor II drives the elliptical wheels to rotate, causing the screen plate to vibrate through periodic pushing action. This vibration not only accelerates the screening speed of qualified materials but also effectively prevents highly viscous toothpaste waste from clogging the screen holes, ensuring the continuity and stability of the entire screening process and improving the automation level of the equipment.

[0031] 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.

[0032] Please see Figure 1-4This embodiment provides a waste recycling and crushing device for toothpaste production, aiming to solve the technical problems of poor crushing effect and easy repeated crushing of qualified materials in the prior art. The device includes an integral crushing chamber 1, which is not a traditional single-cavity structure, but is composed of an independent but interconnected primary crushing chamber 101 and a secondary crushing chamber 102 combined vertically.

[0033] The specific assembly process is as follows: First, the primary crushing chamber 101 is securely installed above the secondary crushing chamber 102. An inlet 103 is welded to the top of the primary crushing chamber 101 for manual or mechanical feeding of toothpaste waste. The bottom of the primary crushing chamber 101 is designed as a funnel-shaped inclined structure. This design utilizes gravity to assist the material in sliding down, ensuring that the material flows smoothly from the bottom outlet 104 into the secondary crushing chamber 102 below. An outlet 105 is provided on one side of the primary crushing chamber 101. A collection chamber 106 is sealed to the outside of the outlet 105. A collection drawer 107 is slidably installed inside the collection chamber 106, specifically for receiving qualified material after primary crushing. Several support legs 1011 are fixedly installed at the four corners of the bottom of the primary crushing chamber 101. In this embodiment, four legs are preferred. Rubber pads are adhered to the bottom of the support legs 1011 to enhance the anti-slip and shock absorption performance of the device.

[0034] The secondary crushing chamber 102 is located directly below the primary crushing chamber 101. Inside the secondary crushing chamber 102, at the top, is a vertically positioned cylindrical crushing compartment 108. The top opening of this compartment is connected to the outlet 104 at the bottom of the primary crushing chamber 101 via a flange or welding, ensuring accurate material entry. The bottom wall and lower side walls of the crushing compartment 108 are densely covered with several sieve holes 109. The diameter of these sieve holes 109 is slightly larger than the final product particle size requirement, serving as the qualification standard for secondary crushing. The bottom of the secondary crushing chamber 102 is also open, with a sliding collection drawer 1010 installed to collect qualified material that has undergone secondary crushing and passed through the sieve holes 109.

[0035] Based on the aforementioned hardware, the core functional components are installed as follows:

[0036] Regarding the installation of crushing component 1.2:

[0037] Please see Figure 1-4Inside the primary crushing chamber 101, two horizontally parallel crushing wheels 201 are installed at the center. The two ends of these crushing wheels 201 are fixed to the side panels of the chamber via bearing seats. To achieve synchronous, opposite-direction rotation to generate strong extrusion and shearing forces, two meshing gears 202 are installed on the outer side of the primary crushing chamber 101, with the central shaft of each gear 202 connected to the corresponding crushing wheel 201. On the other outer side of the primary crushing chamber 101, a high-power motor 203 is fixedly installed, with its output shaft directly coaxially connected to the shaft of one of the crushing wheels 201. When the motor 203 is started, power is transmitted through the meshing gears 202, driving the two crushing wheels 201 to rotate in opposite directions, thus initially crushing the toothpaste waste that falls into it.

[0038] To prevent the material after primary crushing from accumulating in dead corners, a guide plate 5 is installed at an angle, welded to the inside of the primary crushing chamber 101 and directly below the crushing component 2. The lower end of the guide plate 5 points towards the screening component 3, and the upper end is close to the lower edge of the crushing wheel 201. Its function is to guide the crushed material evenly to the screening area.

[0039] Regarding the installation and working principle of screening component 3:

[0040] Please see Figure 3-5 The screening component 3 is a key component for achieving grading. It mainly consists of a screen plate 301, a guide plate 302, a receiving plate 303, a spring 304, an elliptical wheel 305, and a motor 306.

[0041] The sieve plate 301 is inclined and installed in the lower middle part of the primary crushing chamber 101, and its surface is covered with a relatively coarse screen. At the lower end of the sieve plate 301 (i.e., the discharge end), a guide plate 302 is vertically fixed. The sieve plate 301 and the guide plate 302 are rigidly connected in an acute-angle inclined staggered manner, and the free end of the guide plate 302 is precisely aligned with the inside of the discharge port 105.

[0042] On the inner wall of the primary crushing chamber 101, at the position corresponding to the higher end (i.e., the feed end) of the screen plate 301, a receiving plate 303 is horizontally welded and fixed. Two strong springs 304 are bolted between the receiving plate 303 and the screen plate 301. The springs 304 are in a naturally stretched state, providing an upward rebound force to the screen plate 301.

[0043] An elliptical wheel 305 is rotatably mounted on the outer wall of the primary crushing chamber 101 via a bearing seat. The major axis of the elliptical wheel 305 is directly opposite the lower end of the screen plate 301. The elliptical wheel 305 is driven to rotate by a motor 306 fixed outside the chamber. When the motor 306 starts, the elliptical wheel 305 performs continuous eccentric rotation. As the elliptical wheel rotates, its distal end periodically presses against the lower end of the screen plate 301, forcing the screen plate 301 to move downward against the tension of the spring 304; when the elliptical wheel rotates to the proximal end, the spring 304 pulls the screen plate 301 back to its original position. This repetitive motion generates high-frequency, low-amplitude vibration in the screen plate 301. At this time, the material after primary crushing falls onto the vibrating screen plate 301. Qualified material with a particle size smaller than the screen hole passes through the screen hole, slides along the guide plate 302 into the discharge port 105, and is caught by the collection drawer 107. Larger particles that do not meet the standard roll along the inclined screen surface to the lowest end under the vibration of the screen plate, and finally fall into the secondary crushing box 102 below through the outlet 104.

[0044] Regarding the installation of crushing component 2.4:

[0045] Please see Figure 3-4 , Figure 6 A crushing rod 401 is vertically installed at the center of the crushing chamber 108 within the secondary crushing chamber 102. The upper end of the crushing rod 401 is connected to the drive motor via a coupling, and the lower end is fixed to the bottom center of the crushing chamber 108 via a bearing. Three to six high-strength crushing blades 402 are welded and fixed to the rod body of the crushing rod 401 in a spiral or radial staggered pattern. A motor 403 is fixedly installed on the outer wall of the secondary crushing chamber 102, and the output shaft of the motor 403 extends into the chamber and is connected to the bottom end of the crushing rod 401 for transmission. When the motor 403 starts, the crushing rod 401 drives the blades 402 to rotate at high speed within the cylindrical crushing chamber 108. Larger particles falling from above are violently colliding and sheared against the inner wall of the chamber and the blades under the action of centrifugal force and the blades, and are rapidly crushed into smaller particles. When the particle diameter is smaller than the sieve hole 109 at the bottom of the crushing chamber 108, it will fall into the collection drawer 2 1010 for collection.

[0046] The working principle of this utility model:

[0047] Step 1: Primary coarse crushing and guiding

[0048] The motor 203 is started, and its output power drives the directly connected crushing wheel 201 to rotate. Since the two crushing wheels 201 are connected by meshing gears 202, they rotate in opposite directions at the same speed. When the recycled toothpaste waste is fed into the primary crushing chamber 101 through the feed inlet 103, it falls between the two high-speed, oppositely rotating crushing wheels 201 under gravity. Under the squeezing and shearing action of the crushing wheel teeth, the material is rapidly compressed and torn, completing the initial crushing into smaller blocks or granules. The crushed material falls onto the inclined guide plate 5 under gravity, which smoothly guides the material to the screening assembly 3 below.

[0049] Step 2: Vibrating Screening and Diversion

[0050] The material falls onto the screen plate 301 of the screening assembly 3. Simultaneously, motor 306 is started, driving the elliptical wheel 305 to rotate continuously eccentrically. During rotation, the distal end of the elliptical wheel 305 periodically impacts the lower end of the screen plate 301. Since one end of the screen plate 301 is elastically connected to the receiving plate 303 via a spring 304, the impact force of the elliptical wheel causes the screen plate 301 to overcome the spring resistance and move downwards; when the elliptical wheel passes the distal end and continues rotating, the rebound force of the spring 304 pulls the screen plate 301 back to its original position. This periodic impact and rebound causes the screen plate 301 to vibrate at high frequency.

[0051] During the shaking process, qualified materials smaller than the aperture of the sieve plate 301 will fall through the sieve holes and, guided by the second guide plate 302, slide down the inclined surface into the discharge port 105, and finally fall into the collection drawer 107 in the collection box 106 for temporary storage; while unqualified large materials larger than the aperture of the sieve plate cannot pass through the sieve and will roll down the inclined sieve surface under the shaking of the sieve plate 301, and finally collect at the outlet 104 at the bottom of the primary crushing box 101.

[0052] Step 3: Secondary Refinement and Final Collection

[0053] Large pieces of material discharged from outlet 104 fall vertically into the cylindrical crushing chamber 108 at the top of the secondary crushing box 102 under the action of gravity. At this time, motor 3 403 is started, and motor 3 403 drives the crushing rod 401 to drive the several crushing blades 402 on it to rotate at high speed inside the crushing chamber 108.

[0054] After entering the crushing chamber 108, the material is thrown against the inner wall of the chamber under the action of centrifugal force. The high-speed rotating crushing blades 402 exert strong impact, shearing and grinding action on the material, further crushing large pieces of material into fine powder. As the crushing rod 401 continues to rotate, the material in the chamber is constantly agitated and crushed. When the diameter of the material particles is smaller than the aperture of the sieve 109 at the bottom of the crushing chamber 108, these qualified fine powders will fall through the sieve 109 under the interaction of airflow and particles, and will eventually be collected in the collection drawer 1010 at the bottom of the secondary crushing chamber 102.

[0055] For stubborn particles that are still larger than the diameter of the sieve hole 109, they will be blocked in the crushing chamber 108 because they cannot pass through the sieve hole, and will continue to be crushed by the crushing blade 402 for a second or even multiple times until their particle size is small enough to pass through the sieve hole.

[0056] Step 4: Loop and End

[0057] The three steps described above (primary crushing, screening, and secondary grinding) are performed synchronously and continuously during the operation of the equipment. Qualified products from primary grinding are discharged directly, while unqualified products automatically enter secondary grinding. Qualified products from secondary grinding are discharged and collected, while unqualified products are recycled and ground within the chamber. Operators only need to periodically open collection drawer 107 and collection drawer 2010 to retrieve the recycled materials from different stages, or shut down all motors and clean the equipment after the processing task is completed.

[0058] In summary, this utility model uses "vibrating screening" as the core control method and combines two-stage crushing methods with different principles to achieve precise grading of materials. This ensures sufficient crushing while effectively avoiding over-crushing of qualified materials, thus achieving efficient, energy-saving, and high-quality recycling.

[0059] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
