Abstract
Description
Technical Field
[0001] This application relates to the field of spraying equipment technology, and in particular to a movable grid device for spraying equipment. Background Technology
[0002] In industrial spraying operations, workpieces are generally placed on fixed fixtures for spraying. To facilitate maintenance and repair of equipment after spraying, traditional spraying lines will build a fixed grid platform above the fixture, thus creating an upper grid inspection channel. This design allows maintenance personnel to easily enter the channel to inspect, repair, and maintain the various equipment conditions at the lower spraying stations, ensuring the stable operation of the production line.
[0003] The traditional method involves setting up a fixed grid platform on the fixture as a maintenance passage, which is convenient for maintenance, but it occupies a lot of vertical space, resulting in extremely low overall space utilization. Utility Model Content
[0004] The purpose of this application is to provide a movable grid device for spraying equipment, which has the advantages of high space utilization and high flexibility, and solves the problems mentioned in the background art.
[0005] The movable grille device for spraying equipment provided in this application adopts the following technical solution: A movable grille device for spraying equipment includes two shells arranged side by side. The inner sidewall of each shell is fixedly connected to two symmetrically arranged storage rails. Each storage rail has a storage groove inside. Each shell has two symmetrically arranged placement racks on one side. Each placement rack has a sliding groove inside. Each shell has an arc-shaped grille on one side. The two ends of the arc-shaped grille are slidably connected to the placement racks and storage rails through the sliding grooves and storage grooves, respectively. The arc-shaped grille includes equidistant grille bars. A connecting plate is fixedly connected to one side of each grille bar. A connecting rod is fixedly connected to the side of the connecting plate away from the grille bar. A connecting groove is provided on the side of each grille bar opposite to the connecting rod. The connecting rod is rotatably connected to the adjacent grille bar through the adjacent connecting groove. A meshing groove is provided at the bottom end of each grille bar. A rotating shaft is rotatably connected inside the two outer shells. A transmission gear is fixedly connected to the outer circumference of the rotating shaft. The transmission gear meshes with the grille bars through the meshing grooves.
[0006] By adopting the above technical solution, the arc-shaped grid can be moved between the storage groove and the slide groove when the transmission gear rotates and meshes with the meshing groove. Then, during the maintenance of the fixture, the arc-shaped grid can be moved out from the storage track and laid flat on the placement rack to form a maintenance channel, which facilitates the maintenance work. After the maintenance is completed, the arc-shaped grid can be moved out from the placement rack into the storage track to avoid occupying external space and improve space utilization and grid flexibility.
[0007] Preferably, the two outer shells are fixedly connected by bolts.
[0008] By adopting the above technical solution, the two outer shells are fixedly connected by bolts. This connection method has high stability and reliability, which can ensure that the two outer shells are tightly connected and ensure the stability of the overall structure of the device.
[0009] Preferably, a motor and a gearbox are installed on one side of one of the housings, the output end of the motor is fixedly connected to the input end of the gearbox, and the output end of the gearbox is fixedly connected to one end of the rotating shaft.
[0010] By adopting the above technical solution, the power output by the motor is transmitted to the rotating shaft through the gearbox. The gearbox reduces the speed and increases the torque, so that the rotating shaft can drive the transmission gear to rotate at a suitable speed and sufficient torque, thereby driving the arc-shaped grille to move smoothly and realize the grille's unfolding and retracting functions.
[0011] Preferably, the reduction gearbox is a worm gear reducer, and the reduction gearbox has a built-in worm gear transmission structure.
[0012] By adopting the above technical solution, the worm gear reducer has a self-locking function. When the motor stops running, the worm gear transmission structure can prevent the shaft from rotating in the opposite direction, thereby ensuring that the arc-shaped grille is fixed in position after being unfolded or retracted, thus improving the safety and reliability of the device.
[0013] Preferably, the storage track is arranged in an S-shape.
[0014] By adopting the above technical solution, this unique shape design can better guide the movement trajectory of the arc-shaped grille. During the storage and unfolding of the arc-shaped grille, the S-shaped track can make its movement more stable and smooth, reduce friction and jamming between the grille and the track, reduce energy loss, and extend the service life of the device. At the same time, the S-shaped track can also increase the storage space to a certain extent, making the arc-shaped grille more compact when stored, and further saving space.
[0015] Preferably, a T-shaped mounting plate is fixedly connected to the bottom surface of each of the placement racks, and a positioning hole is provided at the bottom of each of the T-shaped mounting plates.
[0016] By adopting the above technical solution, the design of the T-shaped mounting plate increases the contact area between the placement rack and the installation base, improving the stability and firmness of the installation. The positioning holes facilitate the use of bolts and other fasteners to accurately install the placement rack at the top of the fixture station, providing stable support for the unfolded arc-shaped grid.
[0017] Preferably, each of the housings has two maintenance doors hinged to its interior, and each maintenance door has a handle on its outer surface.
[0018] By adopting the above technical solution, a maintenance door is set inside the casing, providing maintenance personnel with a convenient access point for maintenance. When it is necessary to inspect, maintain or replace the internal components of the device, simply open the maintenance door to enter the casing, which greatly improves maintenance efficiency. The handle design on the outer surface of the maintenance door makes it easy for maintenance personnel to open and close the maintenance door, making the operation easier and less strenuous.
[0019] Preferably, each of the outer shells is fixedly connected to a supporting base plate on its bottom surface, and each of the supporting base plates has equidistantly arranged positioning holes inside.
[0020] By adopting the above technical solution, the support base plate provides a stable support foundation for the entire movable grid device, ensuring the stability and balance of the device during operation. The equidistantly arranged positioning holes facilitate the use of bolts and other fasteners to firmly install the device on the working platform of the spraying equipment, preventing the device from moving or shaking during operation and ensuring the normal operation of the device.
[0021] In summary, this application includes at least one of the following beneficial technical effects: This movable grille device for spraying equipment, when driven by a rotating transmission gear engaging with a meshing groove, can move an arc-shaped grille between a receiving groove and a sliding groove. During fixture maintenance, the arc-shaped grille can be moved from the receiving track and laid flat on a placement rack to form a maintenance channel, facilitating maintenance work. After maintenance, the arc-shaped grille can be moved from the placement rack back into the receiving track, avoiding the occupation of external space and improving space utilization and grille flexibility.

Detailed Implementation
[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.
[0025] Example 1: A movable grid device for spraying equipment, referring to... Figures 2-7 It includes two shells 1 arranged side by side. The inner side wall of each shell 1 is fixedly connected to two symmetrically arranged storage rails 2. Each storage rail 2 has a storage groove 3 inside. Each shell 1 has two symmetrically arranged placement racks 4 on one side. Each placement rack 4 has a sliding groove 5 inside. Each shell 1 has an arc-shaped grille 6 on one side. The two ends of the arc-shaped grille 6 are slidably connected to the placement rack 4 and the storage rail 2 through the sliding groove 5 and the storage groove 3, respectively.
[0026] The arc-shaped grille 6 includes equidistant grille bars 601. A connecting plate 602 is fixedly connected to one side of each grille bar 601. A connecting rod 603 is fixedly connected to the side of the connecting plate 602 away from the grille bar 601. A connecting groove 604 is provided on the side of each grille bar 601 opposite to the connecting rod 603. The connecting rod 603 is rotatably connected to the adjacent grille bar 601 through the adjacent connecting groove 604. A meshing groove 605 is provided at the bottom end of each grille bar 601. A rotating shaft 7 is rotatably connected inside the two outer shells 1. A transmission gear 8 is fixedly connected to the outer circumference of the rotating shaft 7. The transmission gear 8 meshes with the grille bar 601 through the meshing groove 605.
[0027] One of the outer casings 1 has a motor 9 and a gearbox 10 installed on one side. The output end of the motor 9 is fixedly connected to the input end of the gearbox 10, and the output end of the gearbox 10 is fixedly connected to one end of the rotating shaft 7. The power output by the motor 9 is transmitted to the rotating shaft 7 through the gearbox 10. The gearbox 10 reduces the speed and increases the torque, so that the rotating shaft 7 can drive the transmission gear 8 to rotate at a suitable speed and sufficient torque, thereby driving the arc-shaped grille 6 to move smoothly and realize the grille's unfolding and retracting functions.
[0028] Example 2: A movable grid device for spraying equipment, referring to... Figure 1 , Figure 3 and Figure 4 The reduction gearbox 10 is a worm gear reducer with a built-in worm gear transmission structure. The worm gear reducer has a self-locking function. When the motor 9 stops running, the worm gear transmission structure can prevent the rotating shaft 7 from rotating in the opposite direction, thereby ensuring that the arc-shaped grille 6 is fixed in position after being unfolded or retracted, which improves the safety and reliability of the device.
[0029] The storage track 2 is S-shaped. This unique shape design can better guide the movement trajectory of the arc-shaped grille 6. During the storage and unfolding of the arc-shaped grille 6, the S-shaped track can make its movement more stable and smooth, reduce friction and jamming between the grille and the track, reduce energy loss, and extend the service life of the device. At the same time, the S-shaped track can also increase the storage space to a certain extent, making the arc-shaped grille 6 more compact when stored, further saving space.
[0030] Each placement rack 4 has a T-shaped mounting plate 11 fixedly connected to its bottom surface. Each T-shaped mounting plate 11 has a positioning hole at its bottom. The design of the T-shaped mounting plate 11 increases the contact area between the placement rack 4 and the installation base, improving the stability and firmness of the installation. The positioning hole makes it easy to use bolts or other fasteners to accurately install the placement rack 4 at the top of the fixture station, providing stable support for the unfolded arc-shaped grid 6.
[0031] Each housing 1 has two maintenance doors 12 hinged inside. Each maintenance door 12 has a handle on its outer surface. The maintenance doors 12 inside the housing 1 provide convenient access for maintenance personnel. When it is necessary to inspect, maintain or replace the internal components of the device, simply open the maintenance door 12 to enter the housing 1, which greatly improves maintenance efficiency. The handle design on the outer surface of the maintenance door 12 makes it easy for maintenance personnel to open and close the maintenance door 12, making the operation easier and less strenuous.
[0032] The two outer shells 1 are fixedly connected by bolts. This method of fixing the two outer shells 1 with bolts has high stability and reliability, ensuring that the two outer shells 1 are tightly connected and guaranteeing the stability of the overall structure of the device.
[0033] Each outer shell 1 has a fixed support base plate 13 on its bottom surface. Each support base plate 13 has equidistantly arranged positioning holes inside. The support base plate 13 provides a stable support foundation for the entire movable grid device, ensuring the stability and balance of the device during operation. The equidistantly arranged positioning holes facilitate the use of bolts or other fasteners to firmly install the device on the working platform of the spraying equipment, preventing the device from moving or shaking during operation and ensuring the normal operation of the device.
[0034] The implementation principle of this application embodiment is as follows: The spraying equipment fixture can be placed below the placement frame 4, and then the placement frame 4 is installed at a suitable position at the top of the fixture station using bolts through the T-shaped mounting plate 11. When the spraying equipment fixture needs to be repaired, the motor 9 is started. The motor 9 outputs power and transmits it to the input end of the reduction gearbox 10 fixedly connected to it. The power after reduction is transmitted from the output end of the reduction gearbox 10 to one end of the rotating shaft 7, causing the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it drives the transmission gear 8 fixed on its outer circumference to rotate together. The transmission gear 8 meshes with the meshing groove 605 opened at the bottom end of each grid bar 601 on the arc-shaped grid 6. Under the meshing action, the transmission gear 8 drives the arc-shaped grid 6 to move. The two ends of the arc-shaped grille 6 are slidably connected to the placement frame 4 and the storage track 2 through the sliding groove 5 inside the placement frame 4 and the storage slot 3 inside the storage track 2, respectively. Driven by the transmission gear 8, the arc-shaped grille 6 moves out from the storage slot 3 in the storage track 2 and lays flat on the placement frame 4 along the sliding groove 5 to form a maintenance channel, which facilitates maintenance personnel to carry out maintenance work on the spraying fixture station and provides convenience for the staff. After the maintenance is completed, the control motor 9 rotates in the opposite direction. Similarly, through the transmission of the reduction gearbox 10, the rotating shaft 7 and the transmission gear 8, the arc-shaped grille 6 moves out from the placement frame 4 along the sliding groove 5 and returns to the storage slot 3 in the storage track 2, avoiding the occupation of external space and improving the space utilization and the flexibility of the grille.
