Description

Technical Field

[0001] The utility model relates to the technical field of fastener production equipment, in particular to chemical glue drying equipment. Background Art

[0002] Chemical glue used for fasteners and screws is usually called fastening glue or anaerobic sealant. This glue is mainly used to ensure that the screws do not fall off during operation.

[0003] The problems with the existing technology are: 1. Chemical glue is applied to the threaded surface of the fastener, which needs to be dried and cured. However, the traditional method is to send the fasteners covered with chemical glue into an oven for drying in batches. The batch placement method causes inconsistent contact between the hot air in the oven and each fastener, resulting in differences in drying efficiency.

[0004] Moreover, when the axial length of the fasteners varies, the amount of chemical glue applied is also different, and the hot air for drying needs to be adjusted. For example, the longer the axial length of the fastener, the higher the hot air flow rate needs to be, thereby improving the drying efficiency.

[0005] 2. When fasteners are dried, the surface moisture evaporates, causing the air humidity in the oven to increase, which will affect the subsequent drying efficiency of the fasteners.

[0006] Therefore, in response to the above problems, it is necessary to improve the design of existing drying equipment. Utility Model Content

[0007] In order to solve the deficiencies of the above technologies, the utility model provides a chemical glue drying device.

[0008] The utility model further provides: a chemical glue drying device, comprising an air guide cover, an air inlet pipe, an air outlet pipe, an air blowing mechanism, and a carrier mechanism for conveying fasteners, wherein the air guide cover is provided with a material transfer channel adapted to the contour of the carrier mechanism, and the fasteners are arranged on the carrier mechanism and pass through the material transfer channel along with the carrier mechanism;

[0009] The blowing mechanism includes a blower and a heating pipe. One end of the air inlet pipe and the air outlet pipe is connected to the material transfer channel, and the other end is connected to the blower. The blower draws air from the material transfer channel through the air outlet pipe, heats it through the heating pipe, and then transports it to the material transfer channel for circulation through the air inlet pipe.

[0010] Further configuration of the present invention: the equipment also includes a guide plate, an articulated seat and a driving mechanism. The articulated seat is arranged at the junction of the air inlet pipe and the material transfer channel. The guide plate is hingedly connected to the articulated seat and cooperates with the driving mechanism. The driving mechanism controls the flipping angle of the guide plate relative to the articulated seat.

[0011] By adopting the above technical solution, a guide plate that can be flipped relative to the hinged seat is set at the junction of the air inlet pipe and the material transfer channel, so that the guide plate can be used to control the angle of the air flow blown out of the air inlet pipe, so that the blowing angle and flow rate of the blown air flow can be changed according to the process requirements of the product being dried, thereby improving the drying efficiency.

[0012] A further configuration of the present invention is that the driving mechanism includes a stepping motor and a transmission assembly.

[0013] By adopting the above technical solution, a stepper motor is used to control the rotation angle of the guide plate. The transmission component is connected to the output end of the stepper motor and the hinged shaft set to be hinged with the guide plate. The transmission component can adopt conventional solutions such as gear sets and sprockets, so it will not be repeated here to make the stepper motor and the guide plate linked.

[0014] Further configuration of the present invention: the equipment also includes a three-way pipe, a humidity detector and an air valve. One of the three-way pipes is an air supply port, and the other two ports are connected to the air inlet pipe and the blower respectively. The air valve is arranged at the air supply port to control the opening and closing of the air supply port. The humidity detector is arranged in the feed channel and is connected to the air valve signal. The air valve opens and closes according to the humidity signal of the feed channel.

[0015] With this technical solution, when fasteners are dried with hot air, moisture on their surfaces evaporates. Because the feed channel, air inlet duct, and air outlet duct form a relatively sealed internal loop, this prevents heat loss and saves energy. However, this also causes moisture to accumulate, resulting in excessive humidity within the feed channel and affecting drying efficiency.

[0016] Therefore, by setting up a three-way pipe, a humidity detector and an air valve, when the humidity detector detects that the humidity in the material transfer channel exceeds the warning value, the detection signal is transmitted to the PLC controller, and the PLC controller controls the air valve to open, and the external air enters the internal circulation pipeline for mixing, thereby reducing the humidity. When the humidity detection signal is lower than the warning value, the air valve is closed.

[0017] The utility model is further configured as follows: the transport mechanism includes a rotating platform and a magnetic turntable, the outer circumference of the magnetic turntable is magnetically attracted to the fastener, and the rotating platform drives the magnetic turntable to rotate;

[0018] The air guide cover is in an arc shape that matches the diameter of the magnetic turntable. The material transfer channel is arranged at the inner diameter end face of the air guide cover and matches the contour of the magnetic turntable.

[0019] By adopting the above technical solution, the transport mechanism can adopt a variety of fastener conveying methods, such as common tracks, conveyor belts, etc. However, the present application prefers the method of rotating the magnetic turntable, which uses magnetic attraction to attract one end of the head of the fastener, while the screw portion of the fastener extends radially outward, making it easier to accurately apply chemical glue to the screw portion. In addition, the fasteners are adsorbed on the outer peripheral surface of the magnetic turntable and arranged in a single row. The extended posture of the screw portion reduces the wind blocking between each other, facilitating full contact with hot air when passing through the material transfer channel, thereby improving drying efficiency.

[0020] The utility model is further configured as follows: the air guide cover is provided with a plurality of groups of air inlet pipes, air outlet pipes and air blowing mechanisms.

[0021] Adopting the above-mentioned technical solution, as shown in the attached drawings of the specification, the embodiment of the present application preferably arranges air inlet ducts on both sides of the air guide hood and air outlet ducts in the middle section of the air guide hood, and the hot air blows from both sides to the middle section, thereby reducing the distance from a single set of air inlet ducts to the air outlet ducts, thereby reducing the attenuation of wind speed and heat due to the long distance, and the collision of the counter-blowing forms in the middle section also forms local turbulence, further enhancing the drying effect.

[0022] According to this design concept, the air guide cover can also be set to several strokes, with a set of air inlet pipes and air outlet pipes set in each stroke.

[0023] A further configuration of the present invention is that the outer surface of the air guide cover is covered with a heat-insulating material.

[0024] By adopting the above technical solution, the heat loss of the air guide cover is reduced, thereby saving energy consumption.

[0025] The beneficial effects of the present invention are as follows: the present invention forms hot air internal circulation drying through the structural design of the air guide cover, air inlet pipe, air outlet pipe, blowing mechanism and the carrying mechanism for conveying fasteners; and controls the hot air angle and flow rate through the design of the guide plate; avoids the situation of excessive humidity in the hot air internal circulation through the design of the three-way pipe, humidity detector and air valve; realizes energy-saving internal circulation hot air drying.

[0032] To make the technical solution and its advantages of the present application clearer, the technical solution of the present application will be described in further detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of the present application and are only used to explain the present application, not to limit the present application. It should be noted that, for ease of description, only the parts related to the present application are shown in the accompanying drawings, and other related parts can refer to the general design. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other to obtain new embodiments.

[0033] The present invention is described in detail below with reference to the accompanying drawings. Figure 1-4 As shown,

[0034] A chemical adhesive drying device includes an air guide hood 1, an air inlet pipe 2, an air outlet pipe 3, an air blowing mechanism 4, and a carrier mechanism for conveying fasteners 5. The air guide hood 1 is provided with a material transfer channel adapted to the contour of the carrier mechanism. The fasteners 5 are arranged on the carrier mechanism and pass through the material transfer channel along with the carrier mechanism.

[0035] The blowing mechanism 4 includes a blower and a heating pipe. One end of the air inlet pipe 2 and the air outlet pipe 3 is connected to the feed channel, and the other end is connected to the blower. The blower draws air from the feed channel through the air outlet pipe 3, heats it through the heating pipe, and then transports it to the feed channel through the air inlet pipe 2 for circulation.

[0036] The equipment also includes a guide plate 11, an articulated seat 12 and a driving mechanism 13. The articulated seat 12 is arranged at the junction of the air inlet pipe 2 and the material transfer channel. The guide plate 11 is hingedly connected to the articulated seat 12 and cooperates with the driving mechanism 13. The driving mechanism 13 controls the flipping angle of the guide plate 11 relative to the articulated seat 12.

[0037] By setting a guide plate 11 at the junction of the air inlet pipe 2 and the material transfer channel, which can be flipped relative to the hinge seat 12, the guide plate 11 is used to control the angle of the air flow blown out of the air inlet pipe 2, so that the blowing angle and flow rate of the blown air flow can be changed according to the process requirements of the product being dried, thereby improving the drying efficiency.

[0038] The driving mechanism 13 includes a stepping motor and a transmission assembly.

[0039] A stepper motor is used to control the rotation angle of the guide plate 11. The transmission component connects the output end of the stepper motor and the hinge shaft that is hinged to the guide plate 11. The transmission component can adopt conventional solutions such as gear sets and sprockets, so it will not be repeated here to make the stepper motor and the guide plate 11 linked.

[0040] The equipment also includes a three-way pipe 31, a humidity detector and an air valve. One of the three-way pipe 31 is an air supply port 32, and the other two ports are connected to the air inlet pipe and the blower respectively. The air valve is arranged at the air supply port 32 to control the opening and closing of the air supply port 32. The humidity detector is arranged in the feed channel and is connected to the air valve signal. The air valve opens and closes according to the humidity signal of the feed channel.

[0041] When the fasteners 5 are dried by hot air, moisture on their surfaces evaporates. Because the feed channel, air inlet pipe 2, and air outlet pipe 3 form a relatively sealed internal circulation system, this prevents heat loss and saves energy. However, this also causes moisture to accumulate, resulting in excessive humidity within the feed channel and affecting drying efficiency.

[0042] Therefore, by setting up a three-way pipe 31, a humidity detector and an air valve, when the humidity detector detects that the humidity in the material transfer channel exceeds the warning value, the detection signal is transmitted to the PLC controller, and the PLC controller controls the air valve to open, and the external air enters the internal circulation pipeline for mixing, thereby reducing the humidity. After the humidity detection signal is lower than the warning value, the air valve is closed.

[0043] The transport mechanism includes a rotating platform 61 and a magnetic turntable 62. The outer circumference of the magnetic turntable 62 is magnetically attracted to the fastener 5. The rotating platform 61 drives the magnetic turntable 62 to rotate.

[0044] The air guide cover 1 is in an arc shape that matches the diameter of the magnetic turntable 62 . The material transfer channel is provided at the inner diameter end face of the air guide cover 1 and matches the contour of the magnetic turntable 62 .

[0045] The transport mechanism can employ a variety of methods for conveying fasteners 5, such as common rails and conveyor belts. However, the present application prefers a rotating magnetic turntable 62, which magnetically engages the head end of the fastener 5, while the screw portion of the fastener 5 extends radially outward, facilitating precise application of chemical adhesive to the screw portion. Furthermore, the fasteners 5 are attached to the outer circumference of the magnetic turntable 62 in a single row. The extended position of the screw portion reduces wind blocking, facilitating full contact with the hot air as the fasteners pass through the feed channel, thereby improving drying efficiency.

[0046] The air guide cover 1 is provided with a plurality of groups of air inlet pipes 2, air outlet pipes 3, and air blowing mechanisms 4.

[0047] As shown in the drawings of the specification, the embodiment of the present application preferably sets air inlet ducts 2 on both sides of the air guide hood 1, and sets air outlet ducts 3 in the middle section of the air guide hood 1. Hot air blows from both sides to the middle section, reducing the distance from a single set of air inlet ducts 2 to the air outlet ducts 3, thereby reducing the attenuation of wind speed and heat due to excessive distance. Moreover, the collision of the counter-blowing forms in the middle section also forms local turbulence, further enhancing the drying effect.

[0048] According to this design concept, the air guide cover 1 can also be set to several strokes, and each stroke is provided with a set of air inlet pipes 2 and air outlet pipes 3.

[0049] The outer surface of the air guide cover 1 is covered with a heat-insulating material.

[0050] The heat loss of the air guide cover 1 is reduced, thereby saving energy consumption.

[0051] The present application forms hot air internal circulation drying through the structural design of the air guide cover 1, the air inlet pipe 2, the air outlet pipe 3, the blowing mechanism 4 and the carrying mechanism for conveying fasteners 5; and controls the hot air angle and flow rate through the design of the guide plate 11; avoids excessive humidity in the hot air internal circulation through the design of the three-way pipe 31, the humidity detector and the air valve; and realizes energy-saving internal circulation hot air drying.

Those skilled in the art should understand that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or replacements to the relevant technical features, and the technical solutions after these changes or replacements will fall within the scope of protection of the present application.
