According to the anti-caking agent spraying device, the anti-caking agent is sprayed out in an atomized mode through the spraying device, so that the anti-caking agent is attached to the surfaces of the hot melt adhesive particles, in this way, when the hot melt adhesive particles fall into the material collecting container, the hot melt adhesive particles are separated from one another through a protective film formed by the anti-caking agent and are not sticky, and therefore the problem that the hot melt adhesive particles are sticky during accumulation is solved. Besides, the anti-blocking agent is sprayed in a vaporific manner and wraps the surfaces of the hot melt adhesive particles, so that even if the hot melt adhesive particles are placed for a long time, the hot melt adhesive particles cannot be stuck and blocked, and the problem that the hot melt adhesive particles are stuck and blocked can be fundamentally solved. The device has the advantages of being simple in structure, low in production cost, high in practicability and suitable for being popularized vigorously.

[0001] The utility model relates to the field of hot melt adhesive, in particular to a production system for preventing hot melt adhesive particles from agglomerating. Background Art

[0002] Hot melt adhesive particles are a type of thermoplastic adhesive that melts when heated and solidifies quickly after cooling to form a strong bond. Hot melt adhesive particles are widely used in various industrial fields, including packaging, furniture manufacturing, woodworking, electronic assembly, automobile manufacturing, etc. Hot melt adhesive particles are favored due to their advantages such as fast bonding, easy operation, no solvent volatilization, and environmental protection.

[0003] There are two main methods for forming hot melt rubber pellets, one is extrusion method and the other is water bath method. The extrusion method is to use an extruder to heat, melt, mix and extrude the pretreated raw materials, and then obtain hot melt rubber pellets by cooling, cutting and other methods. The water bath method uses continuous mixing, heats the raw materials into a water bath state, and then obtains the finished hot melt rubber pellets by cooling, cutting and other methods.

[0004] Due to the characteristics of the raw materials of hot melt adhesive particles, the hot melt adhesive particles produced by the equipment are easy to stick together and agglomerate if they are not treated. In the prior art, drying equipment is often used to dry the hot melt adhesive particles to alleviate the problem of hot melt adhesive particles sticking and agglomerating. However, the existing solution is costly and cannot solve the problem of hot melt adhesive particles sticking and agglomerating when stored for a long time. Utility Model Content

[0005] The utility model aims to solve the above problems and provides a production system for preventing hot melt rubber particles from agglomerating by spraying an anti-caking agent so that the anti-caking agent can be attached to the surface of the hot melt rubber particles produced by the discharge port to avoid sticking and agglomerating with each other.

[0006] In order to solve the above-mentioned problem, the utility model provides a production system for preventing hot-melt adhesive particles from agglomerating, characterized in that a spray device is provided near the discharge port of the hot-melt adhesive particles, and the spray device can spray an atomized anti-caking agent toward the hot-melt adhesive particles when the hot-melt adhesive particles are produced at the discharge port, so that the anti-caking agent is attached to the surface of the hot-melt adhesive particles to avoid sticking to each other and agglomerating.

[0007] Furthermore, the spray device comprises a nozzle, and the spraying direction of the nozzle is toward the output path of the hot melt adhesive particles.

[0008] Furthermore, the anti-caking agent is silicone oil.

[0009] Furthermore, the spray device comprises a storage bin and a conveying system, the storage bin is used to store the anti-caking agent, and the conveying system is at least connected to the nozzle.

[0010] Furthermore, the conveying system is fixedly connected to the storage bin, and the conveying system can pump the anti-caking agent in the storage bin to the nozzle.

[0011] Furthermore, the conveying system is separately arranged from the storage bin, and the other end of the conveying system opposite to the nozzle can be immersed in the storage bin to pump the anti-caking agent in the storage bin to the nozzle.

[0012] Furthermore, the spray device is arranged in linkage with the discharge port, and when the discharge port stops discharging, the spray device automatically stops spraying; when the discharge port starts discharging, the spray device automatically sprays atomized anti-caking agent toward the hot melt rubber particles.

[0013] Furthermore, the spray device also includes a fixing mechanism, through which at least the nozzle can be fixed to the discharge port.

[0014] Furthermore, the fixing mechanism comprises a hoop in an embracing shape, the hoop can be embracing on the outer wall of the discharge port and can be separated from the outer wall of the discharge port, and the nozzle is arranged on the hoop.

[0015] Furthermore, a plurality of nozzles are provided on the hoop.

[0016] The beneficial contribution of the utility model is that it effectively solves the above-mentioned problems. The main points of the production system for preventing hot-melt rubber particles from agglomerating in the utility model are that a spray device is arranged near the discharge port of the hot-melt rubber particles, and the anti-caking agent is sprayed out in an atomized state by the spray device, so that it adheres to the surface of the hot-melt rubber particles. In this way, when the hot-melt rubber particles fall into the aggregate container, the hot-melt rubber particles are separated from each other by the protective film formed by the anti-caking agent and do not stick to each other, thereby avoiding the problem of sticking and agglomerating when the hot-melt rubber particles are accumulated. In addition, since the anti-caking agent is sprayed in a mist form and wrapped on the surface of the hot-melt rubber particles, even if the hot-melt rubber particles are left for a long time, the hot-melt rubber particles will not stick and agglomerate, which can fundamentally solve the problem of sticking and agglomerating of the hot-melt rubber particles. The production system for preventing hot-melt rubber particles from agglomerating in the utility model has the characteristics of simple structure and low production cost. It has strong practicality and should be vigorously promoted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following embodiments are provided to further explain and supplement the present invention and do not constitute any limitation to the present invention.

[0022] like Figure 1 to Figure 3 As shown, the main point of the production system for preventing hot melt adhesive pellets from agglomerating is that a spray device 20 is provided near the discharge port 10 of the hot melt adhesive pellets 30. The spray device 20 can spray an atomized anti-caking agent 40 toward the hot melt adhesive pellets 30 when the hot melt adhesive pellets 30 are produced at the discharge port 10, so that the anti-caking agent 40 is attached to the surface of the hot melt adhesive pellets 30 to prevent them from sticking to each other and agglomerating.

[0023] The anti-caking agent 40 can be selected according to the raw material characteristics of the hot melt adhesive, and when it is attached to the surface of the hot melt adhesive particles 30, it can at least prevent the hot melt adhesive particles 30 from sticking to each other. In addition, the anti-caking agent 40 should not affect the properties of the hot melt adhesive particles 30 themselves.

[0024] In this embodiment, the anti-caking agent 40 is silicone oil.

[0025] In other embodiments, the anti-caking agent 40 may also be made of other materials, and is not limited to silicone oil.

[0026] In order to spray the anti-caking agent 40 in a mist form, the spray device 20 includes a nozzle 21. The nozzle 21 is used to spray the anti-caking agent 40 in a mist form. Its atomization structure can refer to the known technology, and the present utility model does not limit it. The spraying direction of the nozzle 21 is toward the output path of the hot-melt adhesive particles 30. In other words, when the anti-caking agent 40 is sprayed from the nozzle 21, the atomized anti-caking agent 40 should be able to fall on the output path of the hot-melt adhesive particles 30, so as to be sprayed on the hot-melt adhesive particles 30, so that when the hot-melt adhesive particles 30 are accumulated in the aggregate container, the hot-melt adhesive particles 30 are isolated from each other by the anti-caking agent 40, thereby avoiding sticking and agglomeration.

[0027] The specific position of the nozzle 21 is not limited, as long as it can spray the anti-caking agent 40 in a mist form and drop it on the hot melt adhesive particles 30 .

[0028] The number of the nozzles 21 is not limited. In some embodiments, Figure 2 As shown, a nozzle 21 may be provided; in some embodiments, as Figure 3As shown, a plurality of nozzles 21 may be provided, for example, two nozzles 21 may be symmetrically provided, and the nozzles 21 spray toward each other, so that the hot melt adhesive particles 30 can be sprayed in all directions and the splash of the anti-caking agent 40 can be reduced.

[0029] In order to spray the anti-caking agent 40 from the nozzle 21 , the spray device 20 further includes a storage bin 22 and a conveying system 23 .

[0030] The storage bin 22 is used to store the anti-caking agent 40, which can be stored in a sealed manner or in an unsealed manner. To facilitate adding the anti-caking agent 40 to the storage bin 22, the storage bin 22 should have a feeding port (not shown in the figure), through which the anti-caking agent 40 can be added to the storage bin 22.

[0031] The capacity of the storage bin 22 can be set as required, and this embodiment does not limit it.

[0032] The conveying system 23 is used to deliver the anti-caking agent 40 in the storage bin 22 to the nozzle 21. The conveying system 23 is at least connected to the nozzle 21.

[0033] In some embodiments, Figure 1 As shown, the conveying system 23 is fixedly connected to the storage bin 22. The conveying system 23 can directly pump the anti-caking agent 40 in the storage bin 22 to the nozzle 21.

[0034] In some embodiments, Figure 2 , Figure 3 As shown, the conveying system 23 is separately arranged from the storage bin 22. The storage bin 22 can be a separate container. One end of the conveying system 23 is connected to the nozzle 21, and the other end can be immersed in the storage bin 22 to pump the anti-caking agent 40 in the storage bin 22 to the nozzle 21.

[0035] The connection form of the storage bin 22, the conveying system 23, and the nozzle 21 is not limited. For example, in some embodiments, the storage bin 22, the conveying system 23, and the nozzle 21 are integrated together to be constructed in the form of a spray gun; in some embodiments, the storage bin 22 can be fixed away from the discharge port 10, the conveying system 23 can be configured as a long and bendable tube, and the nozzle 21 is fixed at one end of the conveying system 23.

[0036] The spray device 20 can be an automatic spray device or a manual spray device. To adapt to the continuous production of the factory, the spray device 20 is preferably an automatic spray device, which can spray automatically and continuously without manual operation once it is started.

[0037] Furthermore, in some embodiments, in order to reduce costs, the spray device 20 can be set to be started and closed separately. When the discharge port 10 produces hot melt adhesive particles 30, manual control is required to open the spray device 20. When the spray device 20 is turned on, the spray device 20 automatically sprays. When the discharge port 10 stops producing hot melt adhesive particles 30, manual control is required to close the spray device 20. When the spray device 20 is closed, the spray device 20 stops spraying. This embodiment is suitable for use in small batch production or trial production, which can greatly reduce production costs.

[0038] In some embodiments, in order to improve production efficiency, the spray device 20 is linked to the discharge port 10. When the discharge port 10 starts to produce hot melt adhesive particles 30, the spray device 20 automatically starts to spray the anti-caking agent 40 in atomized form toward the hot melt adhesive particles 30. When the discharge port 10 stops discharging, the spray device 20 automatically stops spraying. This embodiment has a high degree of automation and does not require manual intervention, which can greatly improve production efficiency.

[0039] Further, in order to facilitate the fixed setting of the spray, the hot melt adhesive particles 30 are sprayed, such as Figure 3 As shown, the spray device 20 further includes a fixing mechanism 24. The fixing mechanism 24 can at least fix the nozzle 21 to the discharge port 10.

[0040] In some embodiments, the fixing structure can fix the entire spray device 20 at the discharge port 10 .

[0041] In this embodiment, the fixing device includes a hoop 241 in an embracing shape, and the hoop 241 can be opened and closed in a ring shape. The hoop 241 can be embraced on the outer wall of the discharge port 10 and can be separated from the outer wall of the discharge port 10. The specific structure of the hoop 241 can refer to the known technology, and this embodiment does not limit it. Generally, the hoop 241 includes two semicircular hoops. One end of the hoop is hinged together, and the other end of the hoop is respectively provided with connecting ears 242, and the connecting ears 242 are respectively provided with screw holes. The connecting ears 242 can be connected together by bolts 243. The distance between the connecting ears 242 can be adapted to the sizes of the discharge ports 10 of different sizes. By tightening the bolts 243, the hoop can be embraced on the outer wall of the discharge port 10, so that the hoop 241 is fixed on the outer wall of the discharge port 10.

[0042] The nozzle 21 is disposed on the hoop 241. Preferably, the nozzle 21 is fixedly disposed on the hoop 241.

[0043] In some embodiments, a nozzle 21 is fixedly mounted on the hoop 241 .

[0044] In this embodiment, two nozzles 21 are fixedly arranged on the hoop 241. Of course, the number of the nozzles 21 can be set as required.

[0045] Furthermore, since the hoop 241 is fixed on the outer wall of the discharge port 10, if the nozzle 21 is directly fixed on the hoop 241, the spraying range of the nozzle 21 may be limited. In order to improve the spraying range of the nozzle 21, an extension arm 244 is provided on the hoop 241. One end of the extension arm 244 is fixedly connected to the hoop 241, and the other end of the extension arm 244 extends outside the outer wall of the discharge port 10. The nozzle 21 is arranged on the end of the extension arm 244. In this way, by extending the extension arm 244, the nozzle 21 can be arranged at a suitable position of the discharge port 10, so that the nozzle 21 can spray in a direction nearly perpendicular to the output of the hot melt adhesive particles 30, thereby improving the spraying range.

[0046] The shape and length of the extension arm 244 can be set as required, and it is used to extend and support the nozzle 21 so as to place the nozzle 21 at a suitable position for spraying.

[0047] The connection mode of the nozzle 21 and the extension arm 244 is not limited, and it can be a fixed connection or a rotational connection. When the nozzle 21 and the extension arm 244 are rotationally connected, the spraying direction of the nozzle 21 can be conveniently adjusted to better meet production needs.

[0048] The rotational connection method between the nozzle 21 and the extension arm 244 is not limited. For example, a universal ball seat can be provided at the end of the extension arm 244, and the nozzle 21 can be clamped on the universal ball seat, so that the spraying direction of the nozzle 21 can be adjusted. For example, the rotational connection method between the nozzle 21 and the extension arm 244 can refer to the connection method between the shower head and the shower head fixing seat. The utility model does not limit its specific structure, and its implementation can refer to various existing known technologies.

[0049] Thus, the production system of the anti-agglomeration of hot melt rubber particles of the utility model is formed. Since the spray device 20 is provided near the discharge port 10, the spray device 20 can spray the anti-agglomeration agent 40 in a mist form, so that the produced hot melt rubber particles 30 are attached with the anti-agglomeration agent 40. When the hot melt rubber particles 30 are accumulated in the aggregate container, the anti-agglomeration agent 40 is mixed between the hot melt rubber particles 30, thereby preventing the hot melt rubber particles 30 from sticking and agglomerating, and fundamentally solving the problem of the hot melt rubber particles 30 sticking and agglomerating. The production system of the anti-agglomeration of hot melt rubber particles of the utility model has a simple structure, is easy to use, and has practical functions. It has a low cost and can solve the problem of the sticking and agglomeration of hot melt rubber particles 30 without changing the existing equipment. It has strong practicality.

[0050] Although the present invention is disclosed through the above embodiments, the scope of the present invention is not limited thereto, and the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the concept of the present invention.
