Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to a bolt pre-coating drying device. Background Technology

[0002] Bolts are common fasteners widely used in mechanical and structural connections. Their manufacturing process includes steps such as raw material selection, forming, heat treatment, and surface treatment. Bolts are usually made of steel, alloy, or stainless steel to ensure strength and corrosion resistance. Before surface treatment, such as coating or plating, bolts need to be cleaned and dried to ensure uniform adhesion and durability of the coating. These treatments can significantly improve the service life and performance of bolts.

[0003] Chinese Patent No. CN219776283U discloses a drying device, including a material guide shell. The material guide shell is fixedly mounted with a circulating extraction drying mechanism via a support frame. A heating element is embedded in the material guide shell, and a base is fixedly mounted at the bottom of the material guide shell. This utility model uses the combination of the circulating extraction drying mechanism and the material guide shell to increase the cyclic agitation and drying of particles, thereby increasing the drying rate and improving production efficiency.

[0004] However, the above-mentioned method dries bolts by circulating and turning the particles, which cannot turn the bolts on the conveyor belt, thus limiting its applicability. Furthermore, the bolts on the conveyor belt may stack due to movement or irregular shape, which will lead to uneven heating on the outer frame of the open flame furnace, thereby affecting the drying effect and reducing production efficiency. Therefore, a bolt pre-coating drying device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] Based on the existing technical problems of drying bolts by circulating and turning the particles, which cannot turn the bolts on the conveyor belt, and the bolts may be stacked on the conveyor belt due to movement or irregular shape, resulting in uneven heating on the outer frame of the open flame furnace, this utility model proposes a bolt coating pre-drying device.

[0006] The present invention discloses a pre-coating drying device for bolts, comprising a frame, wherein a processing device is provided on the outer surface of the frame, the processing device including a smoothing roller, the rotation of the smoothing roller preventing bolt stacking.

[0007] An adjustment device is provided on the outer surface of the frame. The adjustment device includes a rolling roller, and the rotation of the rolling roller causes the bolts to roll.

[0008] Preferably, the processing device further includes a processing motor, which is fixedly installed on the inner wall of the groove of the frame, and the output shaft of the processing motor is fixedly installed on the outer surface of one of the smoothing rollers.

[0009] The above technical solution involves fixing the motor and frame together, and driving a smoothing roller to rotate. The smoothing roller, through its rotation, further separates the bolts, preventing them from sticking together.

[0010] Preferably, another smoothing roller is rotatably connected to the inner wall of the frame via a bearing, and one smoothing roller drives the other smoothing roller to rotate via a bevel gear set. A discharge port is fixedly installed on the outer surface of the frame, and a conveyor belt and an open flame furnace outer frame are fixedly installed on the outer surface of the frame respectively.

[0011] With the above technical solution, one smoothing roller drives another smoothing roller to rotate through a bevel gear set. The two smoothing rollers are set perpendicular to each other, which can effectively correct the position of the bolts that are conveyed from the discharge port to the conveyor belt, reduce their rolling and deviation on the conveyor belt, so as to ensure that the bolts are in a stable and uniform state before entering the outer frame of the open flame furnace.

[0012] Preferably, the adjusting device further includes an adjusting motor, which is fixedly mounted on the outer surface of the frame, and a worm gear is fixedly mounted on the output shaft of the adjusting motor, and a drive gear is slidably sleeved on the output shaft of the adjusting motor.

[0013] The above technical solution involves fixing the motor to the frame, driving the worm gear to rotate, and sliding the motor with the drive gear to rotate without affecting its movement, thus providing precise adjustment functionality.

[0014] Preferably, an electromagnet is fixedly mounted on the output shaft of the regulating motor, the outer surface of the electromagnet is magnetically connected to the outer surface of the drive gear through an adsorption component, and a spring that forces the drive gear to reset is fixedly mounted on the outer surface of the regulating motor.

[0015] With the above technical solution, when the electromagnet is energized, the drive gear rises and disengages from the rotating gear. When the electromagnet is de-energized, the spring resets the drive gear and engages with the rotating gear, thus ensuring that the gear maintains the correct position when needed.

[0016] Preferably, a slide rod is fixedly installed on the outer surface of the frame, and a threaded rod is rotatably connected to the outer surface of the frame via a bearing. A rotating gear is fixedly installed on the outer surface of the threaded rod, and the drive gear meshes with the rotating gear after resetting.

[0017] The above technical solution involves fixing the frame and slide rod together, and connecting the frame and threaded rod via bearings. This fixation does not affect the rotation of the rod. When the electromagnet is de-energized, the spring resets the drive gear, which meshes with the rotating gear to drive the threaded rod to rotate. This allows the movable frame, which is threadedly connected to the threaded rod, to rise and fall on the slide rod.

[0018] Preferably, the outer surface of the threaded rod is threadedly connected to a movable frame, the inner wall of the groove of the movable frame is slidably sleeved with the outer surface of the slide rod, the outer surface of the movable frame is rotatably connected to the outer surface of the rolling roller, a worm gear is fixedly installed on the outer surface of the rolling roller, the worm gear meshes with the worm, and one of the rolling rollers drives the other rolling roller to rotate via a synchronous belt.

[0019] Through the above technical solution, the screw rod is threadedly connected to the movable frame. The rotation of the screw rod drives the movable frame, which is threadedly connected to it, to rise and fall on the sliding sleeve. This, in turn, drives the rolling rollers, which are rotatably connected to the movable frame, to rise and fall. The worm gear on the rolling roller meshes with the worm, driving the rolling rollers to rotate. One rolling roller drives the other rolling roller to rotate via a synchronous belt. By adjusting the height of the rolling rollers, the bolts can be turned over by the rolling rollers. The rolling rollers are equipped with conical spikes. During the rolling of the bolts, the spikes can reduce the contact area with the bolts, thereby increasing the contact area between the bolts and the flame from the side. The conical spikes can also help the bolts roll on the outer frame of the open flame furnace, so that they are exposed to the flame more evenly during the drying process.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. By setting up a processing device to prevent bolt stacking, a processing motor drives a smoothing roller to rotate. The smoothing roller further separates the bolts through its rotation. One smoothing roller drives another smoothing roller to rotate through a bevel gear set. The two smoothing rollers are set perpendicular to each other, which can effectively correct the position of the bolts conveyed from the discharge port to the conveyor belt, reduce their rolling and deviation on the conveyor belt, so as to ensure that the bolts are in a stable and uniform state before entering the outer frame of the open flame furnace. This solves the technical problem that when drying bolts, the bolts on the conveyor belt cannot be turned over due to the inability to do so.

[0022] 2. By setting an adjustment device, the bolt is driven to roll. The adjustment motor drives the worm gear to rotate, the electromagnet is energized, the drive gear rises and disengages from the rotating gear. When the electromagnet is de-energized, the spring resets the drive gear, which then engages with the rotating gear, driving the threaded rod to rotate. This causes the movable frame, which is threadedly connected to the threaded rod, to rise and fall on the sliding sleeve, thereby driving the rolling roller to rise and fall. The worm gear on the rolling roller engages with the worm gear, driving the rolling roller to rotate. One rolling roller drives the other rolling roller to rotate via a synchronous belt. By adjusting the height of the rolling roller, the rolling angle of the bolt on the rolling roller can be changed. The rolling roller is equipped with conical spikes. During the rolling process, the spikes can reduce the contact area with the bolt, thereby increasing the contact area between the bolt and the flame from the side. This solves the technical problem that when drying bolts, they may stack on the conveyor belt due to movement or irregular shape, which will lead to uneven heating on the outer frame of the open flame furnace, thus affecting the drying effect and reducing production efficiency.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figures 1-6 A bolt pre-coating drying device includes a frame 1, and a processing device is provided on the outer surface of the frame 1. The processing device includes a smoothing roller 21, and the rotation of the smoothing roller 21 prevents bolts from stacking.

[0032] To prevent the bolts from sticking together, the processing device also includes a processing motor 2, which is fixedly installed on the inner wall of the groove of the frame 1. The output shaft of the processing motor 2 is fixedly installed on the outer surface of a smoothing roller 21. The processing motor 2 is fixed to the frame 1 and drives the smoothing roller 21 to rotate. The smoothing roller 21 further separates the bolts through its rotation, thus preventing the bolts from sticking together.

[0033] To correct the position of the bolts conveyed from the discharge port 3 to the conveyor belt 31, another smoothing roller 21 is rotatably connected to the inner wall of the frame 1 via a bearing. One smoothing roller 21 drives the other smoothing roller 21 to rotate via a bevel gear set. The discharge port 3 is fixedly installed on the outer surface of the frame 1, and the conveyor belt 31 and the open flame furnace outer frame 32 are fixedly installed on the outer surface of the frame 1 respectively. By rotating the other smoothing roller 21 via the bevel gear set, the two smoothing rollers 21 are set perpendicular to each other, which can effectively correct the position of the bolts conveyed from the discharge port 3 to the conveyor belt 31, reduce their rolling and deviation on the conveyor belt 31, so as to ensure that the bolts are in a stable and uniform state before entering the open flame furnace outer frame 32.

[0034] By setting up a processing device to prevent bolt stacking, the processing motor 2 drives a smoothing roller 21 to rotate. The smoothing roller 21 further separates the bolts through its rotation. One smoothing roller 21 drives another smoothing roller 21 to rotate through a bevel gear set. The two smoothing rollers 21 are set perpendicular to each other, which can effectively correct the position of the bolts conveyed from the discharge port 3 to the conveyor belt 31, reducing their rolling and deviation on the conveyor belt 31, so as to ensure that the bolts are in a stable and uniform state before entering the outer frame 32 of the open flame furnace. This solves the technical problem that when drying bolts, the bolts on the conveyor belt 31 cannot be turned over due to the inability to turn them over during the drying process.

[0035] In order to make the bolts roll, an adjustment device is provided on the outer surface of the frame 1. The adjustment device includes a rolling roller 71, and the rotation of the rolling roller 71 causes the bolts to roll.

[0036] To drive the worm gear 41 to rotate, the adjustment device also includes an adjustment motor 4. The adjustment motor 4 is fixedly installed on the outer surface of the frame 1. The output shaft of the adjustment motor 4 is fixedly installed with the worm gear 41. The output shaft of the adjustment motor 4 is slidably sleeved with a drive gear 42. By fixing the adjustment motor 4 to the frame 1, the adjustment motor 4 drives the worm gear 41 to rotate. By slidingly sleeved with the drive gear 42, the adjustment motor 4 drives the worm gear 41 to rotate without affecting its movement, so as to provide a precise adjustment function.

[0037] To reset the drive gear 42, an electromagnet 5 is fixedly installed on the output shaft of the adjusting motor 4. The outer surface of the electromagnet 5 is magnetically connected to the outer surface of the drive gear 42 through an adsorption component. A spring 51 is fixedly installed on the outer surface of the adjusting motor 4 to force the drive gear 42 to reset. When the electromagnet 5 is energized, the drive gear 42 rises and disengages from the rotating gear 62. When the electromagnet 5 is de-energized, the spring 51 resets the drive gear 42 and engages with the rotating gear 62, so as to ensure that the gear maintains the correct position when needed.

[0038] To drive the threaded rod 61 to rotate, a slide rod 6 is fixedly installed on the outer surface of the frame 1. The threaded rod 61 is rotatably connected to the outer surface of the frame 1 via a bearing. A rotating gear 62 is fixedly installed on the outer surface of the threaded rod 61. After the drive gear 42 is reset, it meshes with the rotating gear 62. The frame 1 is fixedly installed with the slide rod 6, thus fixing it. The frame 1 is rotatably connected with the threaded rod 61 via a bearing, thus fixing it without affecting its rotation. When the electromagnet 5 is de-energized, the spring 51 resets the drive gear 42, which meshes with the rotating gear 62, driving the threaded rod 61 to rotate. This causes the movable frame 7, which is threadedly connected to the threaded rod 61, to rise and fall on the slide rod 6, which is slidably sleeved.

[0039] To increase the contact area between the bolt and the flame, a movable frame 7 is threadedly connected to the outer surface of the threaded rod 61. The inner wall of the groove of the movable frame 7 is slidably sleeved with the outer surface of the slide rod 6. The outer surface of the movable frame 7 is rotatably connected to the outer surface of the rolling roller 71. A worm gear 72 is fixedly installed on the outer surface of the rolling roller 71, and the worm gear 72 meshes with the worm 41. One rolling roller 71 drives the other rolling roller 71 to rotate via a synchronous belt. The movable frame 7 is threadedly connected to the threaded rod 61. When the screw rod rotates, it drives the movable frame 7, which is threadedly connected to it, to rise and fall on the slide rod 6, thereby driving the movable frame 7 to move up and down. The rotating roller 71 is raised and lowered. The worm gear 72 on the roller 71 meshes with the worm 41, driving the roller 71 to rotate. One roller 71 drives the other roller 71 to rotate via a synchronous belt. By adjusting the height of the roller 71, the bolt can be turned over by the roller 71. The roller 71 is provided with conical spikes. During the rolling of the bolt, the spikes can reduce the contact area with the bolt, thereby increasing the contact area between the bolt and the flame from the side. The conical spikes can also help the bolt roll in the outer frame 32 of the open flame furnace, so that it is exposed to the flame more evenly during the drying process.

[0040] By setting an adjustment device, the bolt is driven to roll, the adjustment motor 4 drives the worm gear 41 to rotate, the electromagnet 5 is energized, the drive gear 42 rises and disengages from the rotating gear 62, the electromagnet 5 is de-energized, the spring 51 resets the drive gear 42 and engages with the rotating gear 62, driving the threaded rod 61 to rotate, which in turn drives the movable frame 7, which is threadedly connected to the threaded rod 61, to rise and fall on the sliding sleeve slide rod 6, thereby driving the rolling roller 71 to rise and fall. The worm gear 72 on the rolling roller 71 engages with the worm gear 41, driving the rolling roller 71 to rotate. One rolling roller 71 passes through... Another rolling roller 71 is driven to rotate via a synchronous belt. By adjusting the height of the rolling roller 71, the bolt can be turned over by the rolling roller 71. The rolling roller 71 is provided with conical spikes. During the rolling of the bolt, the spikes can reduce the contact area with the bolt, thereby increasing the contact area between the bolt and the flame from the side. This solves the technical problem that when drying bolts, the bolts may stack on the conveyor belt 31 due to movement or irregular shape, which will lead to uneven heating in the outer frame 32 of the open flame furnace, thus affecting the drying effect and reducing production efficiency.

[0041] Working principle: When it is necessary to separate the bolts before they enter the outer frame 32 of the open flame furnace to prevent them from stacking, the bolts are conveyed from the discharge port 3 to the conveyor belt 31. At the same time, the processing motor 2 is started to drive one smoothing roller 21 to rotate. One smoothing roller 21 drives the other smoothing roller 21 to rotate through a bevel gear set. The two smoothing rollers 21 are set perpendicular to each other, which can effectively correct the position of the bolts conveyed from the discharge port 3 to the conveyor belt 31, reduce their rolling and deviation on the conveyor belt 31, so as to ensure that the bolts are in a stable and uniform state before entering the outer frame 32 of the open flame furnace.

[0042] After the bolt enters the outer frame 32 of the open flame furnace, the rolling roller 71 can be adjusted up and down according to the actual height of the bolt. The adjustment motor 4 is started to drive the worm gear 41 and the drive gear 42 to rotate. The electromagnet 5 is de-energized, and the spring 51 resets the drive gear 42 and meshes with the rotating gear 62, driving the threaded rod 61, which is fixedly installed with the rotating gear 62, to rotate. This causes the movable frame 7, which is threadedly connected to the threaded rod 61, to rise and fall on the sliding rod 6, thereby driving the rolling roller 71, which is rotatably connected to the movable frame 7, to rise and fall. By adjusting the height of the rolling roller 71, the rolling angle of the bolt on the rolling roller 71 can be changed, and it can adapt to different coating types.

[0043] After adjustment, the electromagnet 5 is energized, the drive gear 42 rises and disengages from the rotating gear 62, the worm 41 meshes with the worm wheel 72 fixedly installed on the rolling roller 71 which is rotatably connected to the moving frame 7, and drives the rolling roller 71 to rotate. One rolling roller 71 drives the other rolling roller 71 to rotate through a synchronous belt. The rolling roller 71 is provided with conical spikes. During the rolling of the bolt, the spikes can reduce the contact area with the bolt, thereby increasing the contact area between the bolt and the flame from the side. The conical spikes can also help the bolt roll in the outer frame 32 of the open flame furnace, so that it is exposed to the flame more evenly during the drying process.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
