Description

Technical Field

[0001] This utility model relates to the field of steel cabinet spraying technology, and in particular to a spraying equipment for steel cabinets. Background Technology

[0002] Steel cabinets, due to their sturdy structure and fire and moisture resistance, are widely used in libraries, archives, and data rooms for storing books, documents, and important items. During their production, the side panels need to be assembled with the frame and then coated with a powder coating to enhance corrosion resistance and aesthetics. The uniformity and efficiency of the coating process directly affect product quality and production costs; therefore, optimizing the coating production line is of great importance.

[0003] The existing spraying equipment has the following shortcomings: 1. After the photoelectric sensor detects the position of the workpiece, a series of control logic controls the start and stop of the sprayer. However, the photoelectric sensor is easily covered by the spraying material, requiring frequent shutdowns for cleaning or replacement, which increases maintenance costs; 2. In order to achieve uniform spraying, even if multiple sprayers are arranged at intervals along the vertical direction on each side of the workpiece, lifting equipment is still needed to drive the sprayers to move up or down, and the conveying speed of the workpiece should not be too fast.

[0004] To address this, we designed a spraying equipment for steel cabinets. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a spraying equipment for steel cabinets.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A spraying device for steel cabinets, comprising: The conveyor frame has a sliding bracket at the bottom for suspending workpieces and carrying them from front to back. A gantry is slidably connected to a conveyor frame across and along the front-to-back direction; sprayers are provided on both inner sides of the gantry for spraying the workpiece on both sides; a transverse sliding inclined surface structure is provided at the top of the gantry, which drives the gantry to move backward with the sliding bracket by abutting against the rear side of the sliding bracket, and the inclined surface disengages from the sliding bracket after the gantry moves to its limit position. A reset element is provided on the top surface of the conveyor frame to cause the gantry to reset.

[0007] Furthermore, the transverse sliding ramp structure includes: A transverse sliding rail is installed along the length of the inner top surface of the gantry; The L-shaped sliding block has its vertical section slidably connected to the horizontal slide rail, and its horizontal section has an inclined surface at the outer end corresponding to the moving direction of the sliding bracket. A compression spring is located on the outside of the L-shaped sliding block. It is used to compress the L-shaped sliding block so that its inclined surface can forcefully engage with the sliding bracket, and to drive the L-shaped sliding block to disengage from the sliding bracket and then return to its original position.

[0008] Furthermore, a trigger switch connected to the sprayer signal is provided on the top surface of the gantry corresponding to the outer side of the L-shaped sliding block, for starting the sprayer.

[0009] Furthermore, the trigger end of the trigger switch is provided with a flexible spring facing the L-shaped sliding block.

[0010] Furthermore, an installation plate is provided on the inner top wall of the gantry corresponding to the outer side of the compression spring. A screw rod coaxial with the compression spring is movably passed through the installation plate. The inner end of the screw rod is connected to the compression spring. An adjusting nut is provided on the outer side of the rod body. The initial elastic potential energy of the compression spring is adjusted by rotating the adjusting nut.

[0011] Furthermore, the reset component includes a linear slide rail that is inclined vertically along the front and rear aisles, with multiple wedge-shaped support seats between the bottom surface of the linear slide rail and the top surface of the conveyor frame, and buffer components at both ends; The gantry is slidably connected to the conveyor frame via a linear slide rail, so as to be reset under the action of gravity.

[0012] Furthermore, the height difference between the two ends of the linear slide rail corresponds to the height difference between two adjacent sprayers on the same side.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The design of the transverse sliding inclined plane structure allows the gantry and sprayer to move a certain distance according to the workpiece. Compared with the existing technology, it can effectively improve the workpiece transmission speed while ensuring that the spraying time of the workpiece remains unchanged, thereby improving the spraying efficiency. 2. Through the coordinated operation of the horizontal sliding inclined structure and the trigger switch, the trigger switch can be triggered and the sprayer can be turned on after the L-shaped sliding block moves laterally. Compared with the existing technology, there is no need to consider the frequent shutdown caused by the photoelectric sensor being covered by the spray material during the spraying process. 3. The inclined design of the linear slide rail in the reset component allows the gantry and sprayer to move upward as they follow the workpiece, replacing the existing lifting equipment (which requires energy) and reducing operating costs.

[0017] Combined with appendix Figure 1-6 A steel cabinet spraying device includes a door frame 3, a reset component 6, a sprayer 4, and a trigger switch 7, as well as a linkage triggering mechanism used in conjunction with the sliding bracket 2 in the conveyor frame 1.

[0018] The gantry 3 spans the conveyor frame 1, and its inner top is equipped with a transverse sliding inclined surface structure 5 containing an L-shaped sliding block 52 and a compression spring 53. When the sliding bracket 2 moves to the spraying area, its rear side abuts against the inclined surface 521 of the L-shaped sliding block 52. The L-shaped sliding block 52 slides outward a certain distance perpendicular to the moving direction of the sliding bracket 2 (the inclined surface 521 is disengaged from the sliding bracket 2). At this time, as the sliding bracket 2 moves, the gantry 3 drives the sprayer 4 to move accordingly, and during this process, the sprayer 4 completes the spraying operation on the workpiece. When the gantry 3 moves to its limit position, that is, when the gantry 3 can no longer move, the sliding bracket 2 moves further to compress the inclined surface 521, and the L-shaped sliding block 52 slides outward further and disengages from the sliding bracket 2.

[0019] The trigger switch 7 is located on the outside of the L-shaped sliding block 52. When the L-shaped sliding block 52 is pushed to the designated position (when the gantry 3 moves with the sliding bracket 2), the trigger switch 7 starts the sprayer 4 to achieve automatic spraying; when the gantry 3 moves to the limit position, the sliding bracket 2 disengages, and the reset component 6 resets the gantry 3.

[0020] Furthermore, the reset component 6 includes a linear slide rail 61 that is inclined vertically. During the movement of the gantry 3, it moves upward under the action of the linear slide rail 61. After the gantry 3 moves to the limit position, the sliding bracket 2 disengages from the contact, and the linear slide rail 61 of the reset component 6 resets the gantry 3 under the action of gravity.

[0021] Example 1, in conjunction with Appendix Figure 1-6 A spraying device for steel cabinets, comprising: The conveyor frame 1 has a sliding bracket 2 at its bottom for suspending the workpiece and carrying it from front to back. Both the conveyor frame 1 and the sliding bracket 2 adopt existing technologies, which will not be described in detail here.

[0022] A gantry 3 is slidably connected to the conveyor frame 1 across and along the front-back direction; sprayers 4 are provided on both inner sides of the gantry 3 for spraying the workpiece on both sides; a transverse sliding inclined surface structure 5 is provided at the top of the gantry 3, which drives the gantry 3 to move with the sliding hanger 2 by engaging with the front side of the sliding hanger 2 through its inclined surface 521, and after the gantry 3 moves to the limit position, its inclined surface 521 disengages from the front side of the sliding hanger 2.

[0023] In some possible implementations, the transverse sliding ramp structure 5 includes a transverse slide rail 51 disposed along the length of the inner top surface of the gantry 3, an L-shaped sliding block 52 slidably connected vertically to the transverse slide rail 51, and a compression spring 53 disposed on the outside of the L-shaped sliding block 52; wherein, the outer end of the horizontal section of the L-shaped sliding block 52 is provided with an ramp 521 corresponding to the moving direction of the sliding bracket 2. That is, when the sliding bracket 2 moves to the spraying area, its rear side abuts against the ramp 521 of the L-shaped sliding block 52, and the L-shaped sliding block 52 slides outward a certain distance along the transverse slide rail 51 (the elastic force of the compression spring 53 and the force of the sliding bracket 2 driving the L-shaped sliding block 52 to move are balanced). At this time, as the sliding bracket 2 moves, the gantry 3 drives the sprayer 4 to move accordingly, and during this process, the sprayer 4 completes the spraying operation on the workpiece; and after the gantry 3 moves to the limit position, the sliding bracket 2 disengages from the L-shaped sliding block 52, and the compression spring 53 drives the L-shaped sliding block 52 to return to its original position.

[0024] The reset component 6 is located on the top surface of the conveyor frame 1 and is used to cause the gantry 3 to reset.

[0025] In some possible implementations, the reset member 6 includes a linear slide rail 61 that is inclined vertically along the front and rear aisles. Multiple wedge-shaped support seats 62 are provided between the bottom surface of the linear slide rail 61 and the top surface of the conveyor frame 1, and buffer members 63 are provided at both ends.

[0026] Furthermore, the gantry 3 is slidably connected to the conveyor frame 1 via a linear slide rail 61; that is, after the gantry 3 moves to its limit position (the gantry 3 abuts against the buffer 63), the sliding bracket 2 disengages from the contact, and the linear slide rail 61 resets the gantry 3 under the action of gravity.

[0027] Specifically, multiple wedge-shaped support seats 62 are provided between the bottom surface of the linear slide rail 61 and the top surface of the conveyor frame 1, making the linear slide rail 61 (lower at the front and higher at the back). With this arrangement, during the spraying process, the gantry 3 not only stops relative to the sliding bracket 2 in the horizontal direction, but also moves upward in the vertical direction. Therefore, it can effectively improve the conveying speed of the workpiece and ensure that it can be sprayed evenly, achieving a high degree of uniformity.

[0028] Furthermore, the height difference between the two ends of the linear slide rail 61 corresponds to the height difference between two adjacent sprayers 4 on the same side; specifically, the height difference between the two ends of the linear slide rail 61 is slightly smaller than the height difference between two adjacent sprayers 4 on the same side. The specific difference is related to parameters such as the spraying range of the sprayer 4, and is not specifically limited here.

[0029] Depending on the requirements, the angle between the axis of the linear guide rail 61 and the horizontal plane is 3 to 10 degrees. Preferably, it is 5 to 8 degrees.

[0030] It is necessary to ensure that when the gantry 3 is not subjected to external force, the gantry 3 can move forward and backward along the linear slide rail 61 and be reset before the next workpiece reaches the spraying area.

[0031] It should be noted that when the gantry 3 moves to its limit position, it will come into contact with the buffer 63 at the upper end of the linear slide rail 61 and will be unable to move forward.

[0032] It should be noted that the area surrounding the spraying equipment can be located in a relatively independent space to prevent the paint from spreading.

[0033] The inner top surface of the gantry 3 is provided with a trigger switch 7 that is connected to the sprayer 4 for signaling, corresponding to the outer side of the L-shaped sliding block 52, and is used to start the sprayer 4.

[0034] As needed, the trigger switch 7 is a mechanical trigger switch 7. Preferably, the trigger end of the trigger switch 7 is provided with a flexible spring 8 facing the L-shaped sliding block 52. As needed, the inner end of the flexible spring 8 can be connected to the L-shaped sliding block 52.

[0035] Example 2, in conjunction with Appendix Figure 5A spraying device for steel cabinets differs from Embodiment 1 in that: an mounting plate 31 is provided on the inner top wall of the door frame 3 at the position corresponding to the outer side of the compression spring 53. A screw 54 coaxial with the compression spring 53 is movably passed through the mounting plate 31. The inner end of the screw 54 is connected to the compression spring 53. An adjusting nut 55 is provided on the outer side of the mounting plate 31. That is, by rotating the adjusting nut 55, the screw 54 is driven to move axially under the action of the compression spring 53, so that the compression spring 53 is further compressed or released, thereby achieving the function of adjusting the initial elastic potential energy of the compression spring 53.
