Description

Technical Field

[0001] The present invention relates to the technical field of carpet raw material granule refinement, and in particular to a hot-melt crushing and refinement device for carpet raw material granules. Background Art

[0002] In the process of carpet production, it is first necessary to perform hot melting, crushing and other treatments on raw material granules to make them reach a suitable state for processing. However, the current mainstream equipment generally adopts an independent design of separating the hot-melting unit and the refinement unit. Although the hot-melt material can be transported to the refinement unit for refinement through a corresponding transfer mechanism, it is difficult to minimize the transfer cycle to avoid rapid heat loss during the transfer process. Moreover, during the transfer, the waste heat generated during the hot-melting process cannot be utilized to assist in heat preservation when the hot-melt material is discharged for refinement, and additional heating equipment needs to be matched for secondary heating to maintain the temperature of the hot-melt material, which leads to a significant increase in energy consumption and serious energy waste.

[0003] In view of the above technical defects, a solution is proposed now. Summary of the Invention

[0004] The purpose of the present invention is to provide a hot-melt crushing and refinement device for carpet raw material granules to solve the above-mentioned technical defects.

[0005] The purpose of the present invention can be achieved by the following technical solutions: A hot-melt crushing and refinement device for carpet raw material granules includes a feeding cylinder and a hot-melt cylinder hermetically and slidably installed outside the feeding cylinder. Heating wires are installed inside the annular side wall of the hot-melt cylinder. The bottom of the feeding cylinder is fixedly communicated with a fine treatment box through a feeding hopper, and a crushing and refinement assembly is arranged inside the fine treatment box.

[0006] The crushing and refinement assembly includes two groups of crushing and forming rollers rotatably installed inside the fine treatment box and two groups of movable plates located below the crushing and forming rollers. A plurality of cutting knives are evenly installed on the opposite sides of the movable plates.

A baffle cover rotatable with the feeding cylinder is fixedly connected to the spline shaft. A rotating ring is rotatably connected to the annular outer wall of the feeding cylinder, and a scraping auxiliary plate slidable with the corresponding scraping plate is fixedly connected to the rotating ring.

[0009] Preferably, support plates are symmetrically welded on both sides of the fine processing box. An electric push rod is fixedly installed between the support plates and the hot melt cylinder, and a support rod that slides with the hot melt cylinder is fixedly connected to the support plates.

[0010] Preferably, a number of annular grooves are equidistantly formed on the outer annular wall of the crushing and forming roller, and a material blocking protrusion adapted to the corresponding annular groove is fixedly connected to the inner side wall of the fine processing box.

[0011] Preferably, gears that mesh with each other are fixedly connected to the roller shafts of the two crushing and forming rollers. A support is welded on the outer wall of the fine processing box, and a second motor for driving one of the crushing and forming rollers to rotate is installed on the support through bolts.

[0012] Preferably, square guiding rods are symmetrically and fixedly connected to both sides of the movable plate, and movable sleeves are fixedly connected to the ends of the square guiding rods.

[0014] The beneficial effects of the present invention are as follows:

[0015] (1) In the present invention, through the sliding of the hot melt cylinder and the feeding cylinder, combined with the rotation of the scraping plate, not only can the transfer treatment of the carpet raw material particles after hot melting be quickly completed, but also the hot melt material on the inner wall of the hot melt cylinder and the outer wall of the feeding cylinder can be cleaned. And combined with the relative sliding of the scraping auxiliary plate and the scraping plate to further clean the scraping plate, it can ensure the cleanliness inside the device, avoid material residue and local overheating; it can also indirectly heat and keep warm the hot melt material in the feeding cylinder during the hot melting process to improve energy utilization rate and achieve the effect of energy-saving use; in addition, combined with the refinement treatment component, hot melting and self-discharging refinement treatment can be carried out synchronously, thereby improving the overall processing efficiency;

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1: Please refer to Figures 1 - 8As shown in the figure, a hot-melt crushing and fine processing device for carpet raw material particles in this embodiment includes a feeding cylinder 1 and a hot-melt cylinder 2 that is hermetically and slidably installed outside the feeding cylinder 1. The hot-melt cylinder 2 and the feeding cylinder 1 adopt a sliding nested structure. After the raw material particles complete the hot-melt process, the hot-melt cylinder 2 accurately lifts along the outer wall of the feeding cylinder 1, synchronously triggering the opening of the feeding channel;

[0032] A heating wire 21 is installed inside the annular side wall of the hot-melt cylinder 2. The carpet raw material particles are added into the hot-melt cylinder 2 outside the feeding cylinder 1. The hot-melt cylinder 2 is heated by the heating wire 21 being energized and generating heat to perform hot-melt processing on the carpet raw material particles. The bottom of the feeding cylinder 1 is fixedly communicated with a fine processing box 12 through a feeding hopper 11, and a crushing and fine processing assembly 3 is arranged inside the fine processing box 12;

[0033] The crushing and fine processing assembly 3 includes two groups of crushing and forming rollers 31 rotatably installed inside the fine processing box 12 and two groups of movable plates 32 located below the crushing and forming rollers 31. A plurality of cutting knives 33 are evenly installed on the opposite sides of the movable plates 32. The movable plates 32 drive the cutting knives 33 to move relative to each other to perform slitting and refinement processing on the strip material, and then discharge it from the fine processing box 12;

[0034] A rotating rod 13 is rotatably installed inside the feeding cylinder 1, and a spiral blade 14 adapted to the feeding cylinder 1 is installed on the rotating rod 13. The rotating spiral blade 14 performs feeding processing, and the hot-melt material is extruded into the top of the crushing and forming roller 31, which not only ensures the discharging efficiency but also increases the compactness of the strip material forming. The two groups of crushing and forming rollers 31 rotate at the same speed and in opposite directions through meshing gears 34 to further crush the hot-melt material.

[0035] The top of the hot-melt cylinder 2 is fixedly connected with a mounting frame 22, and a motor 23 is installed on the mounting frame 22 through bolts. A spline shaft 24 that slides with the rotating rod 13 is fixedly connected to the output shaft of the motor 23. A mounting plate 25 is fixedly installed on the spline shaft 24, and a scraping plate 26 that slides with the hot-melt cylinder 2 and the feeding cylinder 1 is fixedly connected to the mounting plate 25;

[0036] The raw material is hot-melted by heating the hot-melt cylinder 2 with the heating wire 21. The motor 23 drives the spline shaft 24 to drive the scraping plate 26 to rotate. Its scraping trajectory can fully cover the contact area between the inner wall of the hot-melt cylinder 2 and the outer wall of the feeding cylinder 1, forming a dynamic scraping force field. This process not only realizes the rapid transfer of the hot-melt raw material but also completely strips the residual material attached to the inner wall of the device, avoiding problems such as cross-contamination, caking and hardening caused by material residue, and deterioration of the raw material performance caused by local overheating, greatly improving the raw material transfer efficiency and the device cleanliness.

[0037] A plurality of feed inlets 15 are equidistantly arranged at the top of the outer wall of the material feeding cylinder 1. A baffle cover 16 that rotates with the material feeding cylinder 1 is fixedly connected to the spline shaft 24. When the hot melt cylinder 2 rises, the baffle cover 16 separates from the material feeding cylinder 1 to open the feed inlets 15. Combined with the rotation of the scraping plate 26, the hot melt material can smoothly enter the material feeding cylinder 1. At the same time, the hot melt material on the inner wall of the hot melt cylinder 2 and the outer wall of the material feeding cylinder 1 is cleaned. After the hot melt cylinder 2 descends, the baffle cover 16 seals the top of the material feeding cylinder 1 and the feed inlets 15, which can prevent raw material particles from entering the material feeding cylinder 1 when adding carpet raw material particles into the hot melt cylinder 2;

[0038] And the baffle cover 16 fits tightly with the material feeding cylinder 1 to form a sealed heat preservation chamber, avoiding the rapid dissipation of the heat of the hot melt material. At this time, the residual heat continuously dissipated in the hot melt cylinder 2 can penetrate through the cylinder wall of the material feeding cylinder 1 to indirectly and uniformly heat and keep warm the internal hot melt material. By utilizing the residual heat resources in the hot melt cylinder 2, the appropriate temperature and fluidity of the hot melt material can be maintained without additional energy consumption, ensuring that it is always in an ideal secondary processing state, providing a strong guarantee for the efficient operation of the subsequent crushing and fine processing component 3;

[0039] A rotating ring is rotatably connected to the annular outer wall of the material feeding cylinder 1 to avoid the problem of rotational interference of the scraping plate 26 caused by the scraping auxiliary plate 17. And a scraping auxiliary plate 17 that slides with the corresponding scraping plate 26 is fixedly connected to the rotating ring. The scraping plate 26 follows the rising movement of the hot melt cylinder 2. The scraping auxiliary plate 17 can further clean the scraping plate 26 through the relative sliding with the scraping plate 26, ensuring the cleanliness inside the device and reducing material waste.

[0040] Support plates are symmetrically welded on both sides of the fine processing box 12. An electric push rod 18 is fixedly installed between the support plates and the hot melt cylinder 2. A support rod that slides with the hot melt cylinder 2 is fixedly connected to the support plates. The hot melt cylinder 2 is pushed to move up or down relative to the material feeding cylinder 1 by the electric push rod 18. The provided support rod is used to further prevent the hot melt cylinder 2 from rotating relative to the material feeding cylinder 1, thereby reducing the problem of shortening the service life of the electric push rod 18.

[0041] A number of annular grooves are equidistantly arranged on the annular outer wall of the crushing and forming roller 31. The heat-insulated hot melt material is accurately conveyed to the crushing and fine processing component 3. The two crushing and forming rollers 31 rotate in the same speed and in opposite directions, forming a high-strength shearing and extrusion force between the relatively moving roller surfaces, refining and crushing the hot melt material into a uniform strip structure;

[0042] A baffle protrusion that is adapted to the corresponding annular groove is fixedly connected to the inner side wall of the fine processing box 12. On the one hand, it avoids the problem that the hot melt material at the top of the crushing and forming roller 31 is discharged from both sides at the top and cannot be comprehensively refined and processed. On the other hand, it can clean the material in the annular groove.

[0043] On the roller shafts of the two groups of crushing and forming rollers 31, gears 34 that mesh with each other are fixedly connected. The two groups of crushing and forming rollers 31 achieve synchronous reverse rotation through the meshing of the gears 34. A bracket is welded on the outer wall of the fine processing box 12, and a second motor 35 for driving one of the crushing and forming rollers 31 to rotate is installed on the bracket through bolts.

[0044] Embodiment 2: Please refer to Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, in this embodiment, square guiding rods 36 are symmetrically and fixedly connected to both sides of the movable plate 32. The arrangement of the square guiding rods 36 can avoid the problem of relative rotation of the movable plate 32, thereby ensuring the fine cutting effect of the relative movement of the cutting knives 33. And movable sleeves 37 are fixedly connected to the ends of the square guiding rods 36. Oblique guiding grooves 38 for sliding the corresponding square guiding rods 36 are formed through the fine processing box 12.

[0045] During the relative movement of the movable plate 32, with the guidance of the oblique guiding grooves 38 on the square guiding rods 36, it moves downward synchronously, causing the movable plate 32 to move downward synchronously with the strip material, avoiding the problem that the strip material between the cutting knives 33 and the crushing and forming rollers 31 continues to descend and accumulate during the descent of the strip material, which is difficult to achieve uniform particle size refinement.

[0046] A linkage plate 39 is slidably connected to the movable sleeve 37, and a guiding pin 310 is fixedly connected to the top of one side of the linkage plate 39. A cam groove 311 for sliding the corresponding guiding pin 310 is formed on the gear 34. A limiting slide rail for sliding the linkage plate 39 is fixedly connected to the outer wall of the fine processing box 12.

[0047] The limiting slide rail is used to limit and assist the horizontal displacement movement of the linkage plate 39. Through the rotation of the gear 34 and the guidance of the cam groove 311 on the guiding pin 310, the corresponding two groups of linkage plates 39 are driven to move relatively with the movable sleeves 37. The movable sleeves 37 drive the movable plate 32 to move relatively in combination with the square guiding rods 36, causing the movable plate 32 to move relatively and synchronously with the strip material. Multiple cutting knives 33 on the movable plate 32 perform fine cutting and processing on the strip material, and after refinement, it is discharged from the fine processing box 12.

[0048] Embodiment 3: Please refer to Figures 1 - 8 As shown, the present invention also proposes a use method of a hot melt crushing and fine processing device for carpet raw material particles, including the following steps:

[0049] Step 1: Add carpet raw material particles into the interior of the hot-melt cylinder 2 outside the material feeding cylinder 1. Heat the hot-melt cylinder 2 by energizing the heating wire 21 to heat it, and perform hot-melting treatment on the carpet raw material particles. During the hot-melting process, the first motor 23 drives the spline shaft 24 to rotate, and the spline shaft 24 drives the scraping plate 26 to rotate, stirring the raw materials for uniform heating, and scraping the hot-melt materials on the inner wall of the hot-melt cylinder 2 and the outer wall of the material feeding cylinder 1;

[0050] Step 2: After the hot-melting is completed, the piston rod of the electric push rod 18 extends to push the hot-melt cylinder 2 to rise. During the rising process, the material blocking cover 16 is separated from the material feeding cylinder 1, and the feeding port 15 is opened. Combining with the rotation of the scraping plate 26, the hot-melt material in the hot-melt cylinder 2 is promoted to enter the material feeding cylinder 1 through the feeding port 15, and the hot-melt materials on the inner wall of the hot-melt cylinder 2 and the outer wall of the material feeding cylinder 1 are cleaned. And through the relative sliding of the scraping auxiliary plate 17 on the scraping plate 26, the hot-melt materials on the scraping plate 26 are synchronously cleaned. With the rotation of the spline shaft 24 driving the rotating rod 13 to carry the spiral blade 14 to rotate, the hot-melt material is pushed to move downward, and then the hot-melt material is pushed into the fine treatment box 12 in a pushing manner;

[0051] Step 3: After all the hot-melt material in the hot-melt cylinder 2 completely enters the material feeding cylinder 1, the electric push rod 18 causes the hot-melt cylinder 2 to move downward. The material blocking cover 16 seals the top of the material feeding cylinder 1 and the feeding port 15 to prevent carpet raw material particles from entering the material feeding cylinder 1. And when the carpet raw material particles are hot-melted again, the hot-melt material in the material feeding cylinder 1 is indirectly heated and insulated synchronously, and the discharging process is carried out synchronously through the rotating spiral blade 14;

[0052] Step 4: Push the hot-melt material into the fine treatment box 12 on the top of the crushing and forming roller 31 in an extrusion manner, and then enter the rolling groove formed by the corresponding annular grooves of the two groups of crushing and forming rollers 31. The second motor 35 drives one group of crushing and forming rollers 31 to rotate, and the other group of crushing and forming rollers 31 rotates at the same speed and in the opposite direction through the meshing gears 34, further crushing the hot-melt material in the rolling groove and forming it into strip materials with a small diameter;

[0053] Step 5: Through the rotation of the gear 34 and the guiding of the cam groove 311 on the guiding pin 310, the corresponding two groups of linkage plates 39 drive the movable sleeve 37 to move relatively. The movable sleeve 37 drives the movable plate 32 to move relatively in combination with the square guiding rod 36. During the relative movement process, with the guiding of the square guiding rod 36 by the oblique guiding groove 38, it moves downward synchronously, causing the movable plate 32 to move downward synchronously with the strip material. Multiple cutting knives 33 on the movable plate 32 perform slitting and refining treatment on the strip material, and then discharge it from the fine treatment box 12. After one slitting is completed, through the rotation of the gear 34, the cam groove 311 causes the square guiding rod 36 to move back to its original position, causing the cutting knives 33 to separate and move upward for a new round of slitting and refining treatment.

[0054] As mentioned above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
