Description

Technical Field

[0001] This utility model relates to the field of pulverization technology, and in particular to a pulverization device for adhesive raw materials. Background Technology

[0002] Adhesives are typically composed of multiple components, such as resins, fillers, plasticizers, and curing agents—solid or semi-solid raw materials. During production, these raw materials need to be pulverized to an appropriate particle size to ensure more uniform dispersion of the components during mixing, resulting in a more homogeneous mixture. Existing pulverizing devices usually consist of a pulverizing chamber, pulverizing components (such as blades or rotors), a motor, and a discharge port. The motor drives the pulverizing components to rotate at high speed, cutting and grinding the raw materials, which are then discharged through the discharge port. However, semi-solid raw materials are highly viscous, making it difficult for them to fully contact the equipment. Furthermore, ordinary pulverizing components are not adept at cutting semi-solid materials, leading to low pulverizing efficiency that fails to meet production demands. Additionally, the lack of an effective cleaning mechanism means that raw materials remain on the sidewalls of the pulverizing components, causing waste and potentially solidifying and affecting the normal operation of the scraper, thus reducing the device's lifespan and pulverizing effect. Utility Model Content

[0003] This invention proposes an adhesive raw material crushing device, which solves the problem of low raw material crushing efficiency in existing adhesive production.

[0004] The technical solution of this utility model is implemented as follows: An adhesive raw material crushing device includes a cylinder, inside which is a distributing cylinder with multiple distributing holes on its side wall. A driving device is located above the cylinder, driving a crankshaft and a limiting sleeve. The limiting sleeve is fitted onto the crankshaft and placed inside the distributing cylinder. The axes of the cylinder, the distributing cylinder, and the limiting sleeve coincide. The side wall of the limiting sleeve has multiple through holes, along which a scraper slides. One end of the scraper, placed inside the limiting sleeve, is hinged to the crankshaft via a connecting rod. The other end of the scraper, placed outside the limiting sleeve, can abut against the inner wall of the distributing cylinder. The bottom end of the distributing cylinder is a discharge port. A heating device is located on the side wall of the cylinder.

[0005] Furthermore, the drive unit includes a bracket, on which a motor is fixed. A drive gear is fixed to the motor's output shaft. A cover plate is fixed to the top of the limiting sleeve, and a driven gear is fixed to the top of the cover plate. The drive gear is connected to the driven gear via a speed-changing linkage. The speed-changing linkage includes a transmission rod, which is rotatably connected to the bracket. The top of the transmission rod meshes with the drive gear via a large gear, and the bottom of the transmission rod meshes with the driven gear via a small gear. Precise control of the pulverizing effect can be achieved by adjusting the transmission ratio between the various gears.

[0006] Furthermore, multiple scraper telescopic rods are provided above the cylinder body. Each telescopic end of the scraper telescopic rod is equipped with a semi-annular cleaning plate. The inner side of the cleaning plate abuts against the outer wall of the limiting sleeve. Adjacent cleaning plates are spaced apart, and the scraper plate can pass through the spaces between them. The cleaning plates effectively remove residual raw materials, reducing waste within the equipment and improving material utilization.

[0007] Furthermore, a pressure ring slides between the cylinder and the distribution cylinder. The outer wall of the pressure ring abuts against the cylinder, and the inner wall of the pressure ring abuts against the distribution cylinder. The pressure ring is driven by a screw jack. By applying pressure to the raw material to be crushed by the pressure ring, the raw material can be more densely distributed in the distribution cylinder, thereby increasing the speed at which the raw material passes through the distribution holes.

[0008] Furthermore, the discharge port is equipped with a dispersing device, which includes a chamber containing a stirring rod fixedly connected to the bottom end of the crankshaft. The stirring action of the stirring rod prevents the raw material from clumping or clogging at the discharge port, thereby improving discharge efficiency and reducing discharge time.

[0009] Compared with existing technologies, this invention improves crushing efficiency by using a crankshaft to drive multiple scraper blades to scrape alternately, meeting general production needs. By changing the feed holes of different diameters or adjusting the rotation speed of the scraper blades driven by the crankshaft, the particle size of the crushed material can be adjusted to meet different production requirements. During the retraction of the scraper blades, the raw material remaining on its side wall is blocked by the limiting sleeve at the through hole, achieving the effect of cleaning the scraper blades, reducing material waste, and preventing the raw material from solidifying on the side wall of the scraper blades and affecting the next use.

Detailed Implementation

[0013] 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.

[0014] like Figure 1-6 As shown, an adhesive raw material crushing device includes a cylinder 1, a distributing cylinder 2 inside the cylinder 1, and multiple distributing holes 3 on the side wall of the distributing cylinder 2. A driving device 4 is located above the cylinder 1, driving a crankshaft 5 and a limiting sleeve 6. The limiting sleeve 6 is sleeved on the crankshaft 5 and placed inside the distributing cylinder 2. The axes of the cylinder 1, the distributing cylinder 2, and the limiting sleeve 6 coincide. The side wall of the limiting sleeve 6 has multiple through holes 7, and a scraper 8 slides along the through holes 7. One end of the scraper 8 placed inside the limiting sleeve 6 is hinged to the crankshaft 5 via a connecting rod, and the other end of the scraper placed outside the limiting sleeve 6 can abut against the inner wall of the distributing cylinder 2. The bottom end of the distributing cylinder 2 is a discharge port 9. A heating device 10 is provided on the side wall of the cylinder 1. The crankshaft 5 is existing technology, and the heating device 10 can be an existing heating wire or other heating device 10. The bottom ends of the dispensing cylinder 2 and the cylinder body 1 are sealed and connected by an annular connecting plate. The center of the connecting plate is connected to a limit ring by multiple connecting rods. The limit ring is rotatably connected to the bottom end of the crankshaft 5.

[0015] During use, place the crushing device on a stable surface, connect the power supply to the heating device 10, and set a reasonable temperature according to the characteristics of the semi-solid raw material. For example, if the raw material softens and has moderate fluidity at 40-50℃, then set the heating device 10 to 45℃. The semi-solid adhesive raw material is then poured into the gap between cylinder 1 and distributing cylinder 2. Under the action of gravity, the raw material flows out along different distributing holes 3. Then, the drive device 4 is started, and the motor drives the crankshaft 5 to rotate, so that the scraper 8 can stably scrape the semi-solid raw material on the inner wall of the distributing cylinder 2, breaking the flowing raw material and thus achieving the effect of crushing. By changing the distributing holes 3 with different diameters or adjusting the rotation speed of the scraper driven by the crankshaft 5, the particle size of the crushed material can be adjusted. During the scraping process, the connecting rod on the crankshaft 5 drives the scraper 8 to slide back and forth in the through hole 7 of the limiting sleeve 6. During the retraction of the scraper 8, the raw material remaining on its side wall will be blocked by the limiting sleeve 6 at the through hole 7, achieving the effect of cleaning the scraper 8. By driving multiple scraper 8 alternately to scrape, the crushing efficiency can be improved.

[0016] like Figure 3 , 4 As shown in Figure 6, the drive device 4 includes a bracket 11, on which a motor is fixed. A drive gear 12 is fixed to the output shaft of the motor. A cover plate 13 is fixed to the top of the limiting sleeve 6. A driven gear 14 is fixed to the top of the cover plate 13. The drive gear 12 is connected to the driven gear through a speed-changing linkage 15. The speed-changing linkage 15 includes a transmission rod. The transmission rod is rotatably connected to the bracket 11. The top of the transmission rod meshes with the drive gear 12 through a large gear, and the bottom of the transmission rod meshes with the driven gear through a small gear.

[0017] During operation, the motor drives the drive gear 12 to rotate via the output shaft. The drive gear 12 first drives the large gear in the transmission linkage 15 to rotate, which in turn drives the transmission rod to rotate. The small gear at the bottom of the transmission rod then drives the driven gear to rotate, thereby driving the limiting sleeve 6. At the same time, the difference in the number of teeth between the large and small gears is used to change the rotational speed. When the rotational speed of the limiting sleeve 6 decreases, the scraper 8 scrapes and crushes the raw material at a slower speed. This avoids over-crushing of the raw material due to excessive speed, thus obtaining a relatively large particle size crushed product to meet specific production needs. For harder semi-solid raw materials, the rotational speed of the limiting sleeve 6 can be increased to increase the movement speed of the scraper 8 and enhance the crushing force, allowing the raw material to be crushed more thoroughly to achieve the required fine particle size. By adjusting the transmission ratio between the various gears, the crushing effect can be precisely controlled.

[0018] like Figure 2 , 3As shown in Figures 5 and 6, multiple scraping telescopic rods are provided above the cylinder 1. Each telescopic end of the scraping telescopic rod is equipped with a semi-annular cleaning plate 16. The inner side of the cleaning plate 16 abuts against the outer wall of the limiting sleeve 6. Adjacent cleaning plates 16 are spaced apart, and the scraper 8 can pass through the spaces between the cleaning plates 16. The scraping telescopic rod is an existing telescopic device, such as a hydraulic rod. When raw material remains on the outer wall of the limiting sleeve 6, the drive device 4 is paused, and the spacing between the scraper 8 and the adjacent cleaning plates 16 aligns. Then, the scraping telescopic rod is activated, causing the cleaning plate 16 to slide along the outer wall of the limiting sleeve 6, thereby cleaning the outer wall of the limiting sleeve 6. This ensures the stability and reliability of the equipment performance and extends its service life. Cleaning can be completed through the telescopic rod's extension and retraction, reducing the difficulty and cost of equipment maintenance.

[0019] like Figure 1 , 3 As shown in Figures 4 and 6, a pressure ring 17 slides between the cylinder 1 and the distribution cylinder 2. The outer wall of the pressure ring 17 abuts against the cylinder 1, and the inner wall of the pressure ring 17 abuts against the distribution cylinder 2. The pressure ring 17 is driven by a screw jack. By applying pressure to the raw material to be crushed through the pressure ring 17, the raw material can be more densely distributed in the distribution cylinder 2, thereby increasing the speed at which the raw material passes through the distribution holes 3. The pressure ring 17 can also ensure that the raw material is evenly distributed around each distribution hole 3 of the distribution cylinder 2, avoiding the problem of insufficient or excessive crushing in some areas due to uneven distribution of raw material, thus improving the uniformity and quality of crushing. By adjusting the screw jack, the pressure of the pressure ring 17 can be flexibly adjusted according to different properties of raw materials and different crushing requirements. For example, for harder or more viscous raw materials, the pressure of the pressure ring 17 can be appropriately increased to ensure that the raw material can pass through the distribution holes 3 smoothly and be fully crushed; while for softer or more brittle raw materials, the pressure can be reduced to avoid over-crushing of the raw material, thus enhancing the adaptability of the equipment.

[0020] like Figure 1 , 2 As shown, a dispersing device is provided at the discharge port 9. The dispersing device includes a chamber 18, inside which a stirring rod 19 is installed. The stirring rod 19 is fixedly connected to the bottom end of the crankshaft 5. Driven by the crankshaft 5, the stirring rod 19 rotates, which can fully stir and disperse the pulverized raw materials at the discharge port 9, preventing the raw materials from clumping or clogging at the discharge port 9, thereby improving discharge efficiency and reducing discharge time. Through the action of the dispersing device, the pulverized raw materials are already in a relatively uniformly dispersed state at the time of discharge, reducing the need for subsequent separate stirring or mixing processes, and lowering production and time costs.

[0021] like Figure 2As shown, deionized water is added to the chamber 18. Deionized water reduces the viscosity of the raw materials, preventing them from becoming too viscous at the outlet 9 and causing blockages, thus improving the smoothness of discharge. Deionized water also helps disperse the raw material particles, resulting in a more uniform distribution of the raw materials at the outlet 9.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
