[0021] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0023] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0026] Example 1, please refer to Figure 1 and Figure 2 As shown, this embodiment proposes an automated production and processing equipment for hot melt adhesive, including a reactor body 1, a foot pad 2 fixedly installed at the bottom of the reactor body 1, a motor 3 fixedly installed at the top of the reactor body 1, and a feed port 4 connected to the top of the reactor body 1.

[0027] like Figure 2 and Figure 3 As shown, a heat dissipation mechanism 5 is provided on the top of the reactor body 1. The heat dissipation mechanism 5 includes an insulating chamber 52. A heat dissipation pipe 51 is fixedly installed inside the insulating chamber 52. The heat dissipation pipe 51 is spirally distributed around the inner wall of the reactor body 1. A water pump is fixedly installed on the heat dissipation pipe 51. Since heat is released during the production process of the hot melt adhesive, the water in the heat dissipation pipe 51 flows along the reactor body 1 through the water pump to dissipate heat from the reactor body 1.

[0028] A flow valve 53 installed inside the heat insulation chamber 52 is fixedly installed on the heat dissipation pipe 51, and a bimetallic coil spring 54 is fixedly installed inside the heat insulation chamber 52. The center of the bimetallic coil spring 54 is fixedly connected to the heat insulation chamber 52, and a heat conduction rod is fixedly installed at the center of the bimetallic coil spring 54. The ambient temperature is transferred to the bimetallic coil spring 54 through the heat conduction rod. The heat conduction rod extends to the outside of the heat insulation chamber 52. The heat insulation chamber 52 is made of glass wool to prevent the heat from being transferred to the heat insulation chamber 52 during the process of the reactor body 1 using the shell to dissipate heat, thereby affecting the temperature of the bimetallic coil spring 54.

[0029] like Figure 4 As shown, an extension bar 55 is fixedly installed at the end of the bimetallic coil spring 54, and the extension bar 55 adopts a U-shaped structure. The avoidance frame 56 is sleeved on the middle part of the extension bar 55. A transmission part is provided at the bottom of the bimetallic coil spring 54, and an adjusting gear 510 connected to the transmission part is fixedly installed at the bottom of the flow valve 53. The transmission part includes a magnet 58, and the magnet 58 is fixedly installed inside the insulation chamber 52. A metal tooth plate 59 is slidably connected inside the insulation chamber 52 and located on the extension line of the end of the magnet 58. The metal tooth plate 59 is meshed with the adjusting gear 510. A magnetic isolation baffle 57 is provided at the end of the bimetallic coil spring 54, and the end of the magnetic isolation baffle 57 is fixedly connected to the avoidance frame 56.

[0030] The magnetic isolation baffle 57 is located between the metal tooth plate 59 and the magnet 58. A sliding groove extending to the magnetic isolation baffle 57 is opened inside the thermal insulation chamber 52. The metal tooth plate 59 slides in the sliding groove. A return spring is elastically connected between the end of the metal tooth plate 59 and the thermal insulation chamber 52. The sliding groove limits the sliding distance of the metal tooth plate 59 to prevent the metal tooth plate 59 and the magnet 58 from being adsorbed together.

[0031] In winter, the heat dissipation efficiency of the reactor body 1 and the heat dissipation pipe 51 is fast. Excessive heat dissipation efficiency will cause the internal temperature of the reactor body 1 to be lower than the temperature required for the reaction. The bimetallic coil spring 54 is affected by the external ambient temperature, and the bimetallic coil spring 54 is affected by the low temperature and retracts. The bimetallic coil spring 54 uses the extension bar 55 and the avoidance frame 56 to move the magnetic isolation baffle 57. Since the magnetic isolation baffle 57 is blocked between the metal tooth plate 59 and the magnet 58, the magnetic isolation baffle 57 moves, and the magnet 58 attracts the metal tooth plate 59. The more the magnetic isolation baffle 57 moves, the larger the area facing each other between the magnet 58 and the metal tooth plate 59, the greater the magnetic force on the metal tooth plate 59, and the greater the distance the metal tooth plate 59 stretches the spring to move. At this time, the metal tooth plate 59 uses the adjusting gear 510 to rotate the flow valve 53.

[0032] In this embodiment, in winter, the bimetallic coil spring 54 is affected by the ambient temperature and is wound. The bimetallic coil spring 54 uses the extension bar 55 and the avoidance frame 56 to move the magnetic isolation baffle 57, so that the magnetic isolation baffle 57 reduces the blocking area of ​​the magnet 58 and the metal tooth plate 59, so that the metal tooth plate 59 is subjected to a greater magnetic force. The metal tooth plate 59 slides to rotate the regulating gear 510 to adjust the flow speed at the flow valve 53, thereby reducing the flow speed in the heat dissipation pipe 51, that is, reducing the cold water heat exchange efficiency, avoiding the ambient temperature affecting the heat dissipation efficiency, and causing the internal temperature of the reactor body 1 to be lower than the temperature required for the reaction.

[0033] Example 2, based on Example 1, this example proposes an automated production and processing equipment for hot melt adhesives, such as Figure 5 and Figure 6 As shown, a heat exchange mechanism 6 is provided inside the feed port 4, and the heat exchange mechanism 6 includes a spiral heat exchange tube 61. The spiral heat exchange tube 61 is opened on the heat dissipation tube 51, and the spiral heat exchange tube 61 is spirally distributed on the outer wall of the feed port 4. The end of the spiral heat exchange tube 61 is fixedly installed with a wheel bin 62, and the interior of the wheel bin 62 is rotatably connected to a water wheel 63. The interior of the feed port 4 is rotatably connected to a spiral propulsion piece 64, and a meshing mechanism is provided between the spiral propulsion piece 64 and the water wheel 63.

[0034] After a batch of hot melt adhesive is produced, it is connected to the spiral heat exchange tube 61 through the heat dissipation pipe 51, which not only reduces the temperature inside the reactor body 1, but also avoids the temperature inside the reactor body 1 being too high when feeding. If the next batch of materials is fed directly, the high temperature may cause the new materials to instantly vaporize and react violently, causing safety hazards.

[0035] The internal temperature of the reactor body 1 is lowered by continuing to flow through the heat dissipation pipe 51, and then a new batch of raw materials is added from the feed port 4 for production. The spiral heat exchange tube 61 is in contact with the feed port 4 to exchange heat with the feed port 4 to heat the raw materials. Due to the low ambient temperature and the low temperature of the raw materials themselves, the original heating temperature cannot heat the raw materials to the reaction temperature within the original heating time, affecting the reaction efficiency, and thus preheating is performed.

[0036] The meshing mechanism includes a first bevel gear 65, which is fixedly mounted on the bottom end of the spiral propulsion piece 64. A second bevel gear 66 is fixedly mounted on the rotating shaft of the water wheel 63. The first bevel gear 65 and the second bevel gear 66 are meshed and connected. A protective plate 67 is fixedly mounted inside the feed port 4. The protective plate 67 adopts an inverted V-shaped structure, and the spiral propulsion piece 64 is rotatably connected to the protective plate 67. The water wheel 63 rotates under the influence of the flow, driving the second bevel gear 66 and the first bevel gear 65 to rotate, so that the spiral propulsion piece 64 rotates. The spiral propulsion piece 64 is used for feeding, and the feeding speed of the raw materials at the spiral propulsion piece 64 is controlled. At the same time, the feeding speed is related to the flow speed to ensure sufficient heat exchange with the raw materials.

[0037] In this embodiment, cooling water is used to impact the water wheel 63 to rotate the second bevel gear 66 and the first bevel gear 65. The first bevel gear 65 drives the spiral propulsion piece 64 to rotate to feed the material, so that the feeding speed is related to the flow speed. The spiral heat exchange tube 61 causes the spiral flow to extend the heat exchange time with the feed port 4, so that sufficient heat exchange can be carried out with the raw material, avoiding the low temperature of the raw material in winter and requiring more heat for heating, and the raw material cannot be heated to the reaction temperature within the original heating time, affecting the reaction efficiency.

[0038] Example 3, based on the above-mentioned Example 1 or Example 2, this example proposes a hot melt adhesive automated production and processing equipment, such as Figure 7 and Figure 8 As shown, the interior of the reactor body 1 is provided with a mixing mechanism 7, which includes a stirring shaft 71. The top end of the stirring shaft 71 is fixedly connected to the output shaft of the motor 3. The outer wall of the stirring shaft 71 is fixedly mounted with a plurality of stirring blades 75 distributed in an annular manner at equal angles. Two adjacent stirring shafts 71 are connected end to end and are rotatably connected to each other. There is a gap of three to ten millimeters between the ends of the stirring blades 75 and the inner wall of the reactor body 1. The stirring shaft 71 and the stirring blades 75 are driven by the motor 3 to rotate to stir and mix the raw materials.

[0039] Multiple agitator shafts 71 are provided. An internal gear ring 72 is fixedly mounted on the top end of each agitator shaft 71, and a docking gear 74 is fixedly mounted on the bottom end of each agitator shaft 71. An intermediate gear 73 meshes between the internal gear ring 72 and the docking gear 74. The bottom of the intermediate gear 73 is rotatably connected to the agitator shaft 71. The internal gear ring 72, the intermediate gear 73, and the docking gear 74 cooperate to cause adjacent agitator shafts 71 to rotate in opposite directions, thereby improving mixing efficiency and generating shear force.

[0040] In this embodiment, the stirring shaft 71 and the stirring blade 75 at adjacent positions rotate in different directions, thereby increasing the turbulence of the fluid inside the reactor body 1 and generating shear force to clean objects attached to the inner wall of the reactor body 1 and improve mixing efficiency.

[0041] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
