Description

Technical Field

[0001] This utility model relates to the field of paint spraying production line technology, and more specifically, to a paint spraying mixing device. Background Technology

[0002] In large-scale painting production lines, the mixing device needs to maintain continuous and stable operation to ensure the uniformity of the paint and the quality of the application. However, due to the viscous nature of the paint, paint residues will inevitably accumulate on the surface of the mixing blades during long-term high-speed operation. These residues not only affect the mixing effect but may also lead to uneven paint mixing, which in turn affects product quality. In addition, the accumulation of residues will increase the load on the mixing motor and reduce the service life of the equipment.

[0003] In existing paint spraying mixing equipment, the mixing blades are usually disassembled and assembled using traditional bolt fixing. This structure is not only cumbersome and time-consuming to disassemble and assemble, requiring professional tools and skilled workers, but also has problems such as easy wear of threads and easy loss of parts. Especially in high-intensity production environments, frequent disassembly and assembly operations not only reduce production efficiency, but also increase the labor intensity of workers, increase the time cost of cleaning and maintenance, and affect the overall production progress.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a paint spraying and mixing device, which has the following beneficial effects:

[0017] 1. The beneficial effects of the stirring mechanism and transmission mechanism are as follows: Through the rotational connection between the swing frame and the support frame, combined with the installation method of the stirring tank on the swing frame, and the meshing transmission of the external gear ring and the gear, the stable rotation of the stirring tank is achieved; at the same time, the motor on the mounting frame provides power, and the transmission belt between the driving wheel and the driven wheel ensures the smoothness of the power output, thereby driving the gear and the external gear ring to mesh and rotate, and finally realizing the stirring tank driving the mounting base and the stirring blade to carry out stable and efficient stirring work.

[0018] 2. The beneficial effects of the snap-fit ​​mechanism, unlocking mechanism, and limiting mechanism are as follows: By connecting the bottom end of the snap-fit ​​rod to the mounting base, the limiting sleeve, push spring, and snap block inside the snap-fit ​​sleeve form an elastic snap-fit ​​structure. At the same time, the movement of the sliding sleeve in the sliding groove drives the push block to act on the protrusion at the top of the snap block, realizing the quick unlocking function. The matching connection between the limiting hole on the support rod and the arc-shaped rod on the outer wall of the rotating sleeve ensures the reliability of the snap-fit ​​state. The sliding cooperation between the positioning groove and the positioning strip, coupled with the guiding effect of the sliding block in the limiting sliding hole, not only ensures the accuracy of installation positioning but also improves the stability of the entire snap-fit ​​structure.

[0019] 3. The beneficial effects of the angle fixing mechanism are as follows: by utilizing the cooperation of multiple sets of fixing grooves and fixing rods on the outer wall of the fixing plate, and by providing pre-tightening force through the compression spring, combined with the operation design of the throttle and handle, the tilting angle of the mixing tank can be quickly adjusted and reliably fixed, making the paint pouring process safer and more convenient. The overall structure not only simplifies the operation process but also improves work efficiency while ensuring safety in use. Attached Figure Description

Multiple sets of adapter grooves 18 are distributed on the outer wall of the locking rod 8 and are adapted to the multiple sets of push blocks 17.

[0031] The transmission mechanism includes a mounting frame 19, a motor 20, a drive wheel 21, a driven wheel 22, and a transmission belt 23. The mounting frame 19 is mounted on one side of the support frame 1. The motor 20 is mounted on the mounting frame 19. The drive wheel 21 is rotatably mounted on the mounting frame 19 and fixedly connected to the output end of the motor 20. The driven wheel 22 is rotatably mounted on the support frame 1 and connected to the gear 5. The transmission belt 23 is disposed on the outer wall of the drive wheel 21 and the driven wheel 22.

[0032] The outer wall of the snap-fit ​​sleeve 10 is provided with a limiting mechanism, which includes a support rod 24, a limiting hole 25, a rotating sleeve 26 and an arc-shaped rod 27. Multiple sets of support rods 24 are installed on the outer wall of the sliding sleeve 16. Multiple sets of limiting holes 25 are distributed at the bottom of multiple sets of support rods 24. The rotating sleeve 26 is rotatably installed on the outer wall of the snap-fit ​​sleeve 10.

[0033] Each of the multiple sets of limiting sleeves 11 has a limiting sliding hole 28, and each of the multiple sets of locking blocks 13 has a sliding block 29 installed on its outer wall. The multiple sets of sliding blocks 29 are slidably installed in the limiting sliding hole 28.

[0034] The inner wall of the snap-fit ​​sleeve 10 is provided with a positioning groove 30, and the outer wall of the snap-fit ​​rod 8 is provided with a positioning strip 31. Both the positioning groove 30 and the positioning strip 31 are provided in multiple sets and are slidably connected.

[0035] In this embodiment, paint is first injected into the mixing tank 3, the motor 20 is started to provide power, the driving wheel 21 is connected to the output end of the motor 20, and the driven wheel 22 is driven to rotate through the transmission belt 23. Driven wheel 22 is connected to gear 5, which in turn drives external gear ring 4 to rotate, realizing the rotational movement of mixing tank 3. The rotation of mixing tank 3 drives mounting base 6 and multiple sets of mixing blades 7 to rotate and mix the paint. When it is necessary to install mixing blades 7, sliding sleeve 16 slides along sliding groove 15, driving multiple sets of push blocks 17 to abut against the protrusions 14 at the top of multiple sets of locking blocks 13 and push them outward, squeezing the push spring 12. Then, the positioning strip 31 on the outer wall of the locking rod 8 at the bottom of the mixing blade 7 is aligned with the positioning groove 30 on the inner wall of the locking sleeve 10 and inserted. When multiple sets of locking grooves 9 move to the inner side of multiple sets of locking blocks 13, the sliding sleeve 16 moves in the opposite direction, driving multiple sets of push blocks 17 to release the abutment against the protrusions 14. When the sliding sleeve 16 moves to the top of sliding groove 15, rotating sleeve 26 drives multiple sets of arc rods. Rotating the sleeve 27 causes multiple sets of arc-shaped rods 27 to be inserted into the limiting holes 25 on the multiple sets of support rods 24, restricting the sliding sleeve 16 and preventing the limiting sleeve 11 from sliding. At the same time, multiple sets of push springs 12 push multiple sets of locking blocks 13 to be locked into the slots 9. The multiple sets of locking blocks slide stably along the limiting sliding holes 28 through the sliding blocks 29 on their outer sides, fixing the locking rod 8 and completing the quick installation of the stirring blade 7. When disassembly is required, rotating the sleeve 26 in the opposite direction causes the arc-shaped rods 27 to disengage from the limiting holes 25, releasing the restriction on the sliding sleeve 16. The sliding sleeve 16 slides along the sliding groove 15, causing multiple sets of push blocks 17 to abut against the protrusions 14 on the top of the multiple sets of locking blocks 13 and push them outward, causing the multiple sets of locking blocks 13 to disengage from the slots 9, releasing the locking rod 8, and allowing the stirring blade 7 to be disassembled.

[0036] Please see Figure 1 As one embodiment of the angle fixing mechanism: an angle fixing mechanism is provided on one side of the support frame 1. The angle fixing mechanism includes a fixing plate 32, a fixing groove 33, a fixing rod 34, a compression spring 35, and a throttle 36. The fixing plate 32 is installed at one end of the swing frame 2. The fixing groove 33 is provided with multiple sets distributed on the outer wall of the fixing plate 32. The fixing rod 34 is slidably installed on the support frame 1. The two ends of the compression spring 35 are respectively connected to the outer wall of the fixing rod 34 and the support frame 1. The throttle 36 is installed on the outside of the fixing plate 32.

[0037] A handle 37 is installed on the outer wall of the fixing rod 34.

[0038] More specifically, when it is necessary to remove the mixed paint, hold the handle 37 and slide the fixed rod 34 downwards, while squeezing the compression spring 35, so that the top of the fixed rod 34 moves out of the fixed groove 33. Then, turn the handle 36 to drive the swing frame 2 to rotate along the support frame 1, causing the mixing bucket 3 to tilt. Then the paint in the mixing bucket 3 can be poured out. The compression spring 35 returns to its original position and pushes the fixed rod 34 so that its top is inserted into the fixed groove 33 to fix the fixed plate 32, so that the swing frame 2 is fixed at an angle.

[0039] In summary, when using or running the entire equipment: first, inject the paint into the mixing tank 3, start the motor 20 to provide power, connect the drive wheel 21 to the output end of the motor 20, and drive the driven wheel 22 to rotate through the transmission belt 23. Driven wheel 22 is connected to gear 5, which in turn drives external gear ring 4 to rotate, realizing the rotational movement of mixing tank 3. The rotation of mixing tank 3 drives mounting base 6 and multiple sets of mixing blades 7 to rotate and mix the paint. When it is necessary to install mixing blades 7, sliding sleeve 16 slides along sliding groove 15, driving multiple sets of push blocks 17 to abut against the protrusions 14 at the top of multiple sets of locking blocks 13 and push them outward, squeezing the push spring 12. Then, the positioning strip 31 on the outer wall of the locking rod 8 at the bottom of the mixing blade 7 is aligned with the positioning groove 30 on the inner wall of the locking sleeve 10 and inserted. When multiple sets of locking grooves 9 move to the inner side of multiple sets of locking blocks 13, the sliding sleeve 16 moves in the opposite direction, driving multiple sets of push blocks 17 to release the abutment against the protrusions 14. When the sliding sleeve 16 moves to the top of sliding groove 15, rotating sleeve 26 drives multiple sets of arc rods. Rotating the sleeve 27 causes multiple sets of arc-shaped rods 27 to be inserted into the limiting holes 25 on the multiple sets of support rods 24, restricting the sliding sleeve 16 and preventing the limiting sleeve 11 from sliding. At the same time, multiple sets of push springs 12 push multiple sets of locking blocks 13 to be locked into the slots 9. The multiple sets of locking blocks slide stably along the limiting sliding holes 28 through the sliding blocks 29 on their outer sides, fixing the locking rod 8 and completing the quick installation of the stirring blade 7. When disassembly is required, rotating the sleeve 26 in the opposite direction causes the arc-shaped rods 27 to disengage from the limiting holes 25, releasing the restriction on the sliding sleeve 16. The sliding sleeve 16 slides along the sliding groove 15, causing multiple sets of push blocks 17 to abut against the protrusions 14 on the top of the multiple sets of locking blocks 13 and push them outward, causing the multiple sets of locking blocks 13 to disengage from the slots 9, releasing the locking rod 8, and allowing the stirring blade 7 to be disassembled.

[0040] When it is necessary to remove the mixed paint, hold the handle 37 and slide the fixed rod 34 downwards, while squeezing the compression spring 35, so that the top of the fixed rod 34 moves out of the fixed groove 33. Then, turn the handle 36 to drive the swing frame 2 to rotate along the support frame 1, causing the mixing bucket 3 to tilt. Then the paint in the mixing bucket 3 can be poured out. The compression spring 35 returns to its original position and pushes the fixed rod 34 so that its top is inserted into the fixed groove 33 to fix the fixed plate 32, so that the swing frame 2 is fixed at an angle.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
