Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a hot melt workshop crusher with automatic feeding function. Background Technology

[0002] A hot melt workshop crusher is a type of mechanical equipment specifically designed for hot melt production workshops. Its main function is to crush scraps generated during the hot melt process, such as hot melt adhesive blocks, hot melt plastic parts, and hot melt film waste, or blocky and granular hot melt raw materials to be processed. Through high-speed rotating blades or grinding components, the material is crushed to a uniform particle size that meets the requirements for subsequent recycling or further processing. It has a structural design that adapts to the characteristics of hot melt materials and is a key auxiliary equipment for achieving material circulation and optimizing costs in the hot melt production process.

[0003] While existing pulverizers used in hot-melt workshops can pulverize different materials, most of them directly pour the material into the pulverizing chamber via conveying equipment. The amount of material poured in at the same time period fluctuates greatly. Excessive pouring can cause excessive load on the pulverizer, affecting its service life and pulverizing quality. Insufficient pouring will affect the material discharge efficiency. Although there are devices on the market that can quantitatively feed pulverizers, the material is affected by temperature during the feeding process. In low-temperature environments, it is easy to harden and the feeding flow is poor, while in high-temperature environments, it is easy to melt and stick to the wall.

[0004] Therefore, this utility model proposes a hot melt workshop crusher with automatic feeding function. Utility Model Content

[0005] Therefore, in order to overcome the common problems of large fluctuations in the amount of material poured into the pulverizer in the same period of time, and the impact of material temperature on the feeding effect, a new method was developed.

[0006] The technical solution of this utility model is as follows: a hot melt workshop crusher with automatic feeding function, including a hopper, a feeding cylinder and a crusher body. The hopper is located on one side above the feeding cylinder. The lower end of the hopper has a conical structure, and the bottom of the conical structure is connected to the feeding cylinder. The inside of the feeding cylinder is provided with a pushing component for compressing and pre-crushing the material. The inner wall of the feeding cylinder is provided with a constant temperature chamber for conducting heat. The crusher body is located below the end of the feeding cylinder away from the hopper. The inside of the hopper is provided with a dispersing mechanism for breaking up wet and agglomerated materials.

[0007] Preferably, the pushing assembly includes a first rotating shaft connected to the feeding cylinder via a bearing. The outside of the first rotating shaft is provided with spiral pushing blades, and the outer wall of the pushing blades fits against the inside of the feeding cylinder. The pitch of the pushing blades gradually decreases with the material conveying direction. The feeding cylinder is provided with a material guide port communicating with the inner cavity at a position opposite to the crusher body. A first geared motor is fixedly installed at one end of the feeding cylinder near the hopper, and the output shaft of the first geared motor is connected to the first rotating shaft via a coupling.

[0008] Preferably, a water storage tank containing constant temperature pure water is provided below the feeding cylinder, and a medium circulation inlet pipe connected to the water storage tank is provided on the left side of the bottom of the constant temperature chamber corresponding to the feeding cylinder, and a circulation pump for circulating constant temperature pure water is installed on the medium circulation inlet pipe. A medium circulation outlet pipe connected to the water storage tank is provided on the right side of the bottom of the constant temperature chamber corresponding to the feeding cylinder.

[0009] Preferably, support bases are fixedly installed on both sides of the bottom of the feeding cylinder, and the bottom of the support bases is fixed to the water storage tank. The two support bases are reserved with holes for the corresponding medium circulation inlet pipe and medium circulation outlet pipe to pass through.

[0010] Preferably, the crusher body has symmetrically installed crushing rollers that rotate in opposite directions inside, a transmission box is fixedly installed on the back of the crusher body, a second reduction motor is installed on the back of the transmission box, and a crushed material outlet trough with an inclined bottom surface is provided on one side of the crusher body.

[0011] Preferably, the dispersing mechanism includes an L-shaped fixing plate welded to the top of the silo, a second rotating shaft extending into the silo is rotatably mounted on the bottom of the horizontal plate on the fixing plate, a dispersing rod with a spiral structure is provided on the outside of the second rotating shaft, and the pitch of the dispersing rod gradually decreases downwards, and a third geared motor for driving the second rotating shaft to rotate is fixedly mounted on the top of the horizontal plate on the fixing plate.

[0012] Preferably, the outer wall of the silo is fixedly installed with a fixing ring, and each of the four corners of the fixing ring is provided with a support column that is fixed to the ground.

[0013] The beneficial effects of this utility model are: 1. When the hot melt workshop pulverizer with automatic feeding function is in use, the first rotating shaft is driven by the first reduction motor to rotate the pushing blades. After the broken material enters the feeding cylinder from the hopper, the rotating pushing blades continuously move the material towards the main body of the pulverizer. As the pitch of the pushing blades gradually decreases with the material conveying direction, it can not only pre-crush the material to reduce the crushing pressure of the main body of the pulverizer, but also compact the loose material, thereby ensuring that the amount of material discharged from the material guide port remains stable. This effectively avoids the problem of large fluctuations in the amount of material poured in the same time period caused by manual or ordinary conveying equipment directly pouring material into existing pulverizers. It prevents the pulverizer load from increasing suddenly when the amount of material poured in is too large, which can easily damage the pulverizer and cause uneven particle size. This extends the service life of the pulverizer and ensures the pulverizing quality. It also avoids the problem of low material discharge efficiency and affecting the production rhythm of the workshop when the amount of material poured in is too small. 2. When using this hot-melt workshop pulverizer with automatic feeding function, a constant temperature chamber is set in the inner wall of the feeding cylinder. The water tank contains pure water, which is kept at a constant temperature by a heating device. During the feeding process, the circulating pump of the medium circulation inlet pipe is turned on to send the medium into the constant temperature chamber, so that the stable temperature in the constant temperature chamber can be directly transferred to the material in the feeding cylinder. This avoids the problem of material hardening and losing fluidity due to insufficient temperature in low-temperature environments, which can block the feeding channel and ensure that the material can be smoothly conveyed to the main body of the pulverizer. It also prevents the material from melting due to excessive temperature in high-temperature environments and sticking to the inner wall of the feeding cylinder, reducing material waste and avoiding the accumulation of sticky material that affects the feeding effect.

[0020] Please see Figures 1-5This utility model provides a technical solution: a hot melt workshop crusher with automatic feeding function, including a hopper 1, a feeding cylinder 2 and a crusher body 3. The hopper 1 is located on one side above the feeding cylinder 2. The lower end of the hopper 1 has a conical structure, and the bottom of the conical structure is connected to the feeding cylinder 2. The inside of the feeding cylinder 2 is provided with a pushing component for pressing and pre-crushing the material. The inner wall of the feeding cylinder 2 is provided with a constant temperature chamber 24 for conducting heat. The crusher body 3 is located below the end of the feeding cylinder 2 away from the hopper 1. The inside of the hopper 1 is provided with a dispersing mechanism 4 for dispersing wet and agglomerated materials. The hopper 1 is used to temporarily store hot melt materials to be crushed. The conical structure at the lower end guides the materials to enter the feeding cylinder 2. The dispersing mechanism 4 pre-treats the wet or lumpy materials in the hopper 1. The pushing component realizes material conveying, compaction and pre-crushing in the feeding cylinder 2. The constant temperature chamber 24 regulates the material temperature through heat conduction. Finally, the material enters the crusher body 3 to complete the crushing. It realizes the continuous process of material from storage to pre-treatment to conveying, which is suitable for the characteristics of hot melt materials that are easy to clump and are greatly affected by temperature.

[0021] The pushing assembly includes a first rotating shaft 22 connected to the feeding cylinder 2 via a bearing. The outside of the first rotating shaft 22 is provided with a spiral pushing blade 23, and the outer wall of the pushing blade 23 is in contact with the inside of the feeding cylinder 2. The pitch of the pushing blade 23 gradually decreases with the material conveying direction. The feeding cylinder 2 is provided with a material guide port 27 connected to the inner cavity at the position opposite to the crusher body 3. A first reduction motor 21 is fixedly installed at one end of the feeding cylinder 2 near the hopper 1, and the output shaft of the first reduction motor 21 is connected to the first rotating shaft 22 via a coupling. As the pitch of the pusher blades 23 gradually decreases along the conveying direction, the material is squeezed and compacted during the conveying process. At the same time, the relative motion between the blades and the material is used to achieve pre-crushing. Finally, the material enters the crusher body 3 stably through the material guide port 27. This solves the problem of large fluctuations in the traditional feeding amount. It reduces the load on the crusher body 3 through pre-crushing and ensures a stable amount of material entering the crusher body 3 through uniform pushing. At the same time, the close fit design between the pusher blades 23 and the inner wall of the feeding cylinder 2 reduces material residue.

[0022] Below the feeding cylinder 2 is a water storage tank 5 containing constant temperature pure water. The left side of the bottom of the constant temperature chamber 24 of the feeding cylinder 2 is provided with a medium circulation inlet pipe 25 connected to the water storage tank 5, and a circulation pump for circulating constant temperature pure water is installed on the medium circulation inlet pipe 25. The right side of the bottom of the constant temperature chamber 24 of the feeding cylinder 2 is provided with a medium circulation outlet pipe 26 connected to the water storage tank 5. The constant-temperature pure water stored in the water storage tank 5 enters the constant-temperature chamber 24 through the medium circulation inlet pipe 25 under the action of the circulation pump. After exchanging heat with the material in the feeding cylinder 2, it flows back to the water storage tank 5 from the medium circulation outlet pipe 26, forming a closed loop to continuously maintain the stable temperature of the medium in the constant-temperature chamber 24. Then, the heat is transferred to the material through the wall of the feeding cylinder 2, which effectively solves the problems of hot-melted materials hardening and having poor fluidity at low temperatures and melting and sticking to the wall at high temperatures. The water storage tank 5 is equipped with a constant-temperature heating component to achieve the temperature treatment of pure water. Since the constant-temperature heating component is a conventional application in existing devices, it will not be described in detail.

[0023] Both sides of the bottom of the feeding cylinder 2 are fixedly installed with support bases 28, and the bottom of the support bases 28 are fixed to the water storage tank 5. The two support bases 28 are reserved with holes for the corresponding medium circulation inlet pipe 25 and medium circulation outlet pipe 26 to pass through. The support base 28 stably supports the feeding cylinder 2 above the water storage tank 5, while the reserved holes provide installation channels for the medium circulation inlet pipe 25 and the medium circulation outlet pipe 26, ensuring that the pipeline layout is reasonable and does not affect the stable operation of the feeding cylinder 2.

[0024] The crusher body 3 has symmetrically installed crushing rollers 31 that rotate in opposite directions inside. A transmission box 32 is fixedly installed on the back of the crusher body 3. A second reduction motor 33 is installed on the back of the transmission box 32. A crushing material outlet trough 34 with an inclined bottom surface is provided on the lower side of one side of the crusher body 3. The crushing efficiency is improved by the opposite rotation of the two crushing rollers 31. The inclined crushing material outlet trough 34 ensures that the crushed material is discharged smoothly and avoids accumulation and blockage. It is adapted to the state of the pre-treated material and ensures that the crushed particle size is uniform. The transmission box 32 has two meshing transmission gears, and the transmission gear shafts are respectively connected to the crushing rollers 31. The second reduction motor 33 drives one of the transmission gears to rotate. Since this gear drive structure is a conventional application of the prior art, it will not be described in detail.

[0025] The dispersing mechanism 4 includes an L-shaped fixed plate 41 welded and fixed to the top of the hopper 1. A second rotating shaft 43 extending into the hopper 1 is rotatably mounted on the bottom of the horizontal plate on the fixed plate 41. A dispersing rod 44 with a spiral structure is provided on the outside of the second rotating shaft 43, and the pitch of the dispersing rod 44 gradually decreases downward. A third reduction motor 42 for driving the second rotating shaft 43 to rotate is fixedly mounted on the top of the horizontal plate on the fixed plate 41. The third reduction motor 42 drives the second rotating shaft 43 to rotate, which in turn drives the spiral dispersing rod 44 to rotate. As the pitch of the dispersing rod 44 gradually decreases downward, it shears, stirs and disperses the wet or lumpy material in the silo 1 during the rotation process, and guides the material to move towards the conical structure at the bottom of the silo 1.

[0026] A fixing ring 11 is fixedly installed on the outer wall of the silo 1, and a support column 12 fixed to the ground is provided at each of the four corners of the fixing ring 11, so as to provide a stable installation foundation for the silo 1 through four-point support.

[0027] Working principle: See Figure 1 and Figure 3 As shown, the hot melt material to be crushed is first put into the hopper 1. The dispersing mechanism 4 is started. The third reduction motor 42 drives the second rotating shaft 43 and the external spiral dispersing rod 44 to rotate. By using the gradually decreasing pitch of the dispersing rod 44, the wet or lumpy material in the hopper 1 is sheared, stirred and dispersed, causing the material to move to the bottom of the hopper 1. Finally, the pre-treated material enters the feeding cylinder 2.

[0028] See Figure 1 , Figure 2 and Figure 4 As shown, during the feeding stage, the first geared motor 21 drives the first rotating shaft 22 and the spiral pusher blades 23 to rotate. The pusher blades 23, with a gradually decreasing pitch along the conveying direction, squeeze, compress, and pre-crush the material entering the feeding cylinder 2. At the same time, because the outer wall of the blades is in contact with the inner wall of the feeding cylinder 2, material residue can be reduced. Finally, the material is stably conveyed to the crusher body 3 through the material guide port 27. During this process, the constant temperature pure water in the water storage tank 5 enters the constant temperature cavity 24 on the inner wall of the feeding cylinder 2 through the medium circulation inlet pipe 25 under the action of the circulation pump. After exchanging heat with the material in the feeding cylinder 2, it flows back to the water storage tank 5 through the medium circulation outlet pipe 26, forming a closed loop circulation, continuously providing a suitable temperature for the material, and avoiding hardening at low temperature or sticking to the wall at high temperature.

[0029] See Figure 5 As shown, after the material enters the main body 3 of the crusher, the second reduction motor 33 drives the two internal crushing rollers 31 to rotate in opposite directions through the transmission box 32, which shears, squeezes and crushes the material. The crushed material slides out through the crushed material outlet trough 34 with the bottom inclined, completing the entire crushing process.

[0030] It should be noted that the aforementioned geared motor can be powered using existing operating techniques, whether by using a power supply unit or an external wire. These are all conventional operating techniques and will not be described in detail here.

[0031] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
