Description

Technical Field

[0001] This utility model relates to the field of transformer parts processing technology, specifically to a transformer parts spraying device. Background Technology

[0002] In the manufacturing process of power transformers, surface protection treatment of metal components such as core clamps, tie plates, oil tanks, and structural parts is a crucial step in ensuring the long-term reliable operation of the product. Traditional protection methods often employ painting, but with increasingly stringent environmental requirements and higher demands for coating performance, powder coating is gradually becoming the mainstream technology for transformer component surface treatment due to its advantages such as zero VOC emissions, high coating utilization rate, thick coating, strong adhesion, excellent corrosion resistance, and superior insulation properties. The powder coating process uses electrostatic spraying equipment to adsorb charged powder particles onto the surface of grounded metal workpieces, which are then cured at high temperatures to form a uniform and dense protective coating. This process not only reduces... Less environmental pollution, lower waste gas treatment costs, and improved physical and chemical properties of the coating make it particularly suitable for transformer components with high requirements for moisture resistance, salt spray resistance, and high temperature resistance. However, most existing powder coating equipment is a general-purpose powder coating production line or a simple manual spray gun operation. General-purpose powder coating lines are usually designed for large batches of regularly shaped workpieces. However, when dealing with transformer parts of different sizes, such as long strip clamps, irregularly shaped pull plates, and perforated structural parts, multiple spray guns still reciprocate according to the originally set maximum stroke for the above-mentioned transformer parts. This operation not only wastes powder particles but also increases the spraying time of individual parts, resulting in low efficiency.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a transformer parts spraying device to solve the technical problem in the related technology that when dealing with transformer parts of different sizes, such as long strip clamps, irregularly shaped pull plates, and perforated structural parts, multiple spray guns still reciprocate spraying according to the originally set maximum stroke. This operation not only wastes powder particles but also increases the spraying time of a single part, resulting in low efficiency.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a transformer parts spraying device is provided, comprising: a spraying component, which is movably arranged and used to spray the transformer parts; and a stroke adjustment component, which is used to adjust the stroke of the spraying component; wherein, when the spraying component contacts the stroke adjustment component, the spraying component moves in the opposite direction.

[0006] Furthermore, the stroke adjustment component includes: a first limit switch, which is movably configured; the first limit switch is configured on one side of the spraying component, and the trigger end of the first limit switch is configured on the movement path of the spraying component; when the spraying component contacts the first limit switch, the first limit switch sends a signal to cause the spraying component to move in the opposite direction.

[0007] Furthermore, it also includes a spraying chamber, a spraying assembly, and a stroke adjustment assembly, all located within the spraying chamber; the stroke adjustment assembly further includes: a connecting plate, which is connected to the first limit switch; and a positioning post, wherein the spraying chamber is provided with multiple positioning holes spaced apart along the height direction of the spraying chamber, and the positioning post passes through the connecting plate and is inserted into the positioning holes to fix the position of the first limit switch.

[0008] Furthermore, the stroke adjustment assembly also includes: a hand plate, which is connected to the end of the positioning post away from the spraying chamber; and a spring, which is located between the hand plate and the connecting plate.

[0009] Furthermore, the spraying assembly includes: a limiting box disposed within the spraying chamber and extending along the height direction of the spraying chamber; a drive screw extending along the height direction of the spraying chamber, passing through the limiting box, and rotatably disposed relative to the spraying chamber; and a nozzle threadedly engaged with the drive screw and movably disposed relative to the limiting box, so that the nozzle moves along the extension direction of the limiting box under the drive of the drive screw.

[0010] Furthermore, it also includes: a recovery assembly, which is used to recover the powder particles sprayed from the nozzle. The recovery assembly includes: a recovery chamber, which is connected to the spraying chamber; a filter box, which is located at the bottom of the recovery chamber; and a recovery pipeline, which is connected to the output end of the filter box.

[0011] Furthermore, a partition is installed inside the spraying chamber, which divides the spraying chamber into an automatic spraying space and a manual spraying space.

[0012] Furthermore, at least one set of spraying components is provided, each set of spraying components has two components, and a stroke adjustment component is provided between each set of spraying components.

[0013] Beneficial effects: 1. By setting a movable spraying component in conjunction with an adjustable stroke adjustment component, the reciprocating stroke of the spraying component can be flexibly and accurately set according to the actual size of the transformer parts being sprayed. This avoids the ineffective spraying of smaller parts due to the fixed stroke of traditional equipment, thereby significantly reducing the waste of powder coating, shortening the spraying cycle of a single part, and improving production efficiency and raw material utilization.

[0014] 2. By setting a hand-held plate connected to the positioning post and a spring between the hand-held plate and the connecting plate, when the position needs to be adjusted, the operator can pull the hand-held plate outward to compress the spring, which will cause the positioning post to disengage from the positioning hole, thereby releasing the lock on the connecting plate and the first limit switch; after the adjustment is in place, the hand-held plate is released, and the restoring force of the spring pushes the positioning post back into the corresponding positioning hole to achieve locking. This structure makes the stroke adjustment operation more labor-saving and convenient.

[0015] 3. By setting up a recovery bin and connecting it to the spraying chamber, oversprayed powder particles that are not adsorbed onto the surface of the parts can fall into the recovery bin under the action of gravity or airflow. After the powder is preliminarily screened by the filter box, it can be transported back to the powder supply system or collection device through the recovery pipeline, realizing the recycling of powder coatings, significantly reducing material consumption costs, and reducing dust emissions, which meets environmental protection requirements.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0019] According to an embodiment of this utility model, a transformer parts spraying device is provided. Please refer to [link / reference]. Figures 1 to 3It includes: a spraying component 1, which is movably disposed and used to spray coating on transformer parts; and a stroke adjustment component 2, which is used to adjust the stroke of the spraying component 1; wherein, when the spraying component 1 contacts the stroke adjustment component 2, the spraying component 1 moves in the opposite direction.

[0020] By adopting the above technical solution, and by setting a movable spraying component 1 in conjunction with an adjustable stroke adjustment component 2, the reciprocating stroke of the spraying component 1 can be flexibly and accurately set according to the actual size of the transformer parts being sprayed. This avoids the ineffective spraying of smaller parts due to the fixed stroke of traditional equipment, thereby significantly reducing the waste of powder coating, shortening the spraying cycle of a single part, and improving production efficiency and raw material utilization.

[0021] Please refer to Figure 2 and Figure 3 The stroke adjustment component 2 includes: a first stroke switch 3, which is movably set; the first stroke switch 3 is set on one side of the spraying component 1, and the trigger end of the first stroke switch 3 is set on the movement path of the spraying component 1. When the spraying component 1 contacts the first stroke switch 3, the first stroke switch 3 sends a signal to make the spraying component 1 move in the opposite direction.

[0022] By adopting the above technical solution, and by setting a movable first limit switch 3 and setting its trigger end on the moving path of the spraying component 1, a simple and reliable position feedback and control mechanism is constructed. When the spraying component 1 moves to and contacts the first limit switch 3, the first limit switch 3 immediately sends an electrical signal to control the spraying component 1 to move in the opposite direction, thereby accurately defining the end position of the unilateral movement of the spraying component 1 and realizing the terminal control of the spraying stroke.

[0023] Please refer to Figure 2 and Figure 3 It also includes a spraying chamber 4, a spraying assembly 1 and a stroke adjustment assembly 2, all located inside the spraying chamber 4; the stroke adjustment assembly 2 also includes: a connecting plate 5, which is connected to the first limit switch 3; a positioning post, in which multiple positioning holes 7 are provided at intervals along the height direction of the spraying chamber 4, the positioning post passes through the connecting plate 5 and is inserted into the positioning holes 7 to fix the position of the first limit switch 3.

[0024] By adopting the above technical solution, the first limit switch 3 is connected to the positioning post through the connecting plate 5, and multiple positioning holes 7 are pre-set on the wall of the spraying chamber 4 to provide multiple discrete and selectable fixed positions for the first limit switch 3. The operator can quickly and coarsely adjust the installation height of the first limit switch 3 by inserting the positioning post into the positioning holes 7 at different heights according to the height of the part, thereby realizing a wide range of adjustment of the spraying stroke.

[0025] Please refer to Figure 3 The stroke adjustment assembly 2 also includes: a hand plate 8, which is connected to the end of the positioning post away from the spraying chamber 4; and a spring 9, which is located between the hand plate 8 and the connecting plate 5.

[0026] By adopting the above technical solution, and by setting a hand-held plate 8 connected to the positioning post and setting a spring 9 between the hand-held plate 8 and the connecting plate 5, when the position needs to be adjusted, the operator can pull the hand-held plate 8 outward to compress the spring 9, so that the positioning post can be disengaged from the positioning hole 7, thereby releasing the lock on the connecting plate 5 and the first limit switch 3; after the adjustment is in place, the hand-held plate 8 is released, and the restoring force of the spring 9 pushes the positioning post back into the corresponding positioning hole 7 to achieve locking. This structure makes the stroke adjustment operation more labor-saving and convenient.

[0027] Please refer to Figure 3 The spraying assembly 1 includes: a limiting box 10, which is disposed in the spraying chamber 4 and extends along the height direction of the spraying chamber 4; a drive screw 14, which extends along the height direction of the spraying chamber 4 and passes through the limiting box 10, and is rotatably disposed relative to the spraying chamber 4; and a spray head 15, which is threadedly engaged with the drive screw 14 and is movably disposed relative to the limiting box 10 so that the spray head 15 moves along the extension direction of the limiting box 10 under the drive of the drive screw 14.

[0028] Furthermore, the limiting box 10 includes a first limiting plate 11, a second limiting plate 12, and a third limiting plate 13 connected in sequence, wherein the first limiting plate 11 and the third limiting plate 13 are arranged opposite to each other, and the second limiting plate 12 is connected to the top of the first limiting plate 11 and the third limiting plate 13; the drive screw 14 passes through the second limiting plate 12 to the bottom of the spraying chamber 4 and is rotatably connected thereto.

[0029] Furthermore, a trigger switch is provided on the second limit plate 12. When the nozzle 15 contacts the trigger switch, the nozzle moves in the opposite direction.

[0030] By adopting the above technical solution, the rotational motion of the drive screw 14 is precisely converted into the linear motion of the nozzle 15 along the vertical direction of the limit box 10 through the threaded engagement between the drive screw 14 and the nozzle 15, thereby achieving precise control of the lifting and lowering of the nozzle 15. The limit box 10 is composed of a first limit plate 11, a second limit plate 12 and a third limit plate 13, which provides a stable moving track and constraint for the nozzle 15, preventing it from shaking or deflecting during movement, and ensuring the uniformity and consistency of the spraying.

[0031] Specifically, multiple drive screws 14 are connected to each other via pulleys and belt drives, and a motor is connected to one of the drive screws 14 to drive the other drive screws 14 to rotate.

[0032] Please refer to Figure 2 It also includes: a recovery component 16, which is used to recover the powder particles sprayed out by the nozzle 15. The recovery component 16 includes: a recovery chamber 17, which is connected to the spraying chamber 4; a filter box 18, which is located at the bottom of the recovery chamber 17; and a recovery pipeline 19, which is connected to the output end of the filter box 18.

[0033] By adopting the above technical solution, and by setting up a recycling bin 17 and connecting it to the spraying chamber 4, the oversprayed powder particles that are not adsorbed on the surface of the parts can fall into the recycling bin 17 under the action of gravity or airflow. After the powder is preliminarily screened by the filter box 18, it can be transported back to the powder supply system or collection device by the recycling pipeline 19, realizing the recycling of powder coating, significantly reducing material consumption costs, and reducing dust emissions, which meets environmental protection requirements.

[0034] Specifically, the filter box 18 includes: a box body, a primary filter, and a fine filter; the box body is installed at the bottom outlet of the recycling bin; the primary filter and the fine filter are detachably arranged inside the box body from top to bottom, the mesh size of the primary filter is smaller than that of the fine filter, and the filtered powder particles enter the recycling pipeline 19 for recycling.

[0035] Furthermore, the filter box also includes a vibrator, which is installed on the outer wall of the box. By setting the vibrator, the primary filter and the fine filter can be made to vibrate slightly from time to time or continuously, thereby shaking off the powder attached to the filter screen, effectively preventing the filter screen pores from being blocked by powder, keeping the filtration channel unobstructed, and ensuring the stability of the airflow and the continuity of the filtration efficiency of the recovery system.

[0036] Please refer to Figure 2 The spraying chamber 4 is also equipped with a partition 20, which divides the spraying chamber 4 into an automatic spraying space and a manual spraying space.

[0037] By adopting the above technical solution, the spraying chamber 4 is physically divided into an automatic spraying space and a manual spraying space by the partition 20, realizing the regional isolation between automatic spraying and manual touch-up spraying or special treatment operations; it can use the automatic spraying component 1 to perform efficient and uniform spraying on batch parts, and can also perform fine operations on complex irregular parts or local parts in the manual spraying space, thus improving the flexibility and applicability of the device.

[0038] Please refer to Figure 2At least one set of spraying components 1 is provided, and two sets of spraying components 1 are provided in each set. A stroke adjustment component 2 is provided between each set of spraying components 1.

[0039] Furthermore, the stroke adjustment assembly 2 also includes a second stroke switch 21. The second stroke switch 21 and the first stroke switch 3 are both located between each group of spraying assemblies 1, and the first stroke switch 3 and the second stroke switch 21 are arranged opposite to each other. The first stroke switch 3 and the second stroke switch 21 are connected by a connecting plate 5 so that the positions of the first stroke switch 3 and the second stroke switch 21 can be adjusted synchronously by a single connecting plate 5.

[0040] By adopting the above technical solution, by setting a stroke adjustment component 2 containing a first limit switch 3 and a second limit switch 21 between two spraying components 1, and using the same connecting plate 5 to connect the two limit switches back to back, the upper and lower limit positions of the reciprocating motion of the two spraying components 1 can be set synchronously with one adjustment operation, ensuring the symmetry and consistency of the stroke when the two spray heads work together, simplifying the adjustment process and improving the setting efficiency.

[0041] It should be noted that at least one first limit switch 3 can be set, and a single first limit switch 3 can control the movement stroke of multiple spray heads 15. The purpose of setting a second limit switch 21 is to prevent damage to a single first limit switch 3 from affecting the smooth progress of the spraying work. The first limit switch 3, the second limit switch 21, and the trigger switch are electrically connected to the motor, and the motor wiring circuit is a forward and reverse circuit.

[0042] Working principle: Before operation, the operator first adjusts the stroke according to the specific dimensions of the transformer parts to be coated: pulling the hand plate 8 outward compresses the spring 9, causing the positioning pin to disengage from the current positioning hole 7 on the wall of the coating chamber 4. Then, the connecting plate 5 is moved up and down, causing the first limit switch 3 and the second limit switch 21 to move synchronously to the required height. Releasing the hand plate 8, the restoring force of the spring 9 pushes the positioning pin into the corresponding positioning hole 7, thus precisely setting the upper and lower limit positions of the reciprocating motion of the nozzle 15. After adjustment, the parts are placed in the coating chamber 4, and the device is started; the drive screw 14 begins to rotate, driving the threaded nozzle 15 to move along the track of the limit box 10, while the nozzle 15 performs powder coating on the parts; when... When the nozzle 15 rises to the point of touching the first limit switch 3, the first limit switch 3 sends a signal to drive the screw 14 to reverse, and the nozzle 15 rises accordingly to spray. When the nozzle 15 rises to the point of touching the trigger switch, the trigger switch sends a signal to drive the screw 14 to reverse again, and the nozzle 15 rises. In this way, it automatically reciprocates within the set stroke until the spraying is completed. During the process, the oversprayed powder that does not adhere to the parts falls into the recovery chamber 17 under the action of gravity. It then passes through the primary filter 23 and the fine filter 24 in the filter box 18 for two-stage filtration. The purified powder can be recycled through the recovery pipeline 19. If manual touch-up spraying is required for irregularly shaped parts, it can be carried out in the manual spraying space separated by the partition 20.
