Description

Technical Field

[0001] The utility model belongs to the technical field of mobile screens, and in particular relates to a positioning mechanism for a mobile screen. Background Art

[0002] The powder coating mobile screen is a screening device used in the powder coating industry. It can help you screen and recycle powder during the coating process. The working principle of the powder coating mobile screen is to generate an exciting force by driving the vibrator through the motor. This force is transmitted to the screen through the spring, so that the screen vibrates in a complex rotation. This vibration makes the material move in a three-dimensional curve on the screen surface, that is, it is projected into a circle in the horizontal direction and an ellipse on the two vertical planes. By adjusting the phase angle of the vibrator, the movement trajectory of the material can be changed to make it gather or disperse. When the material is vibrated, smaller particles will pass through the screen and fall into the collection container at the bottom, while larger particles will be left above the screen, thereby realizing the screening of the material. When using the mobile screen, the operator connects the pipe to the screen bucket in the mobile screen. Therefore, it can be seen that the existing mobile screen basically meets people's practical needs, but there are still the following problems.

[0003] When the operator connects the pipe to the sieve bucket of the mobile screen, the operator first holds the pipe to align the pipe and the sieve bucket, then puts the pipe on the surface of the sieve bucket, and then uses strapping tape and other equipment to tie the pipe tightly to the sieve bucket. However, in order to facilitate the operator to put the pipe on the surface of the sieve bucket, the inner wall diameter of the pipe may be larger than the surface diameter of the sieve bucket, which may cause the pipe to fall off the surface of the sieve bucket after the operator puts the pipe on the surface of the sieve bucket. As a result, after the operator puts the pipe on the surface of the sieve bucket, the operator may need to keep holding the pipe to prevent the pipe from falling off the surface of the sieve bucket during the process of using strapping tape and other equipment to tie the pipe tightly to the surface of the sieve bucket. For this reason, we propose a positioning mechanism for the mobile screen. Utility Model Content

[0004] The utility model provides a positioning mechanism for a mobile screen. After an operator sleeves a pipeline on the surface of a screen cavity, a clamping plate clamps the pipeline on the surface of the screen cavity, pre-fixes the pipeline on the screen cavity, and improves the convenience of the operator in installing the pipeline.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning mechanism for a mobile screen, comprising a mobile frame body and a sieve cavity, the sieve cavity is installed at the end of the mobile frame body, and a fixed frame is symmetrically arranged at the end of the sieve cavity, the fixed frame is rotatably connected to the sieve cavity, and positioning blocks and clamps are respectively fixed to the ends of both sides of the fixed frame, the clamps are in contact with the surface of the sieve cavity, and a plurality of groups of rulers are fixed on one side where the clamps are in contact with the surface of the sieve cavity.

[0006] Furthermore, fixed blocks are symmetrically fixed on the surface of the sieve cavity, and a slide groove is opened in the middle of the fixed blocks. Slide blocks are embedded in the slide grooves, and a ring sleeved on the surface of the sieve cavity and the positioning block is fixed on the surface of the slide block.

[0007] Furthermore, the cross-section of the positioning block is set as a rectangular block, the ring is set on one side of the positioning block as a rectangular groove, and the rectangular groove set on the surface of the positioning block by the ring matches the rectangular block set on the cross-section of the positioning block.

[0008] Furthermore, the collars are all configured as a plurality of groups of wave-shaped grooves.

[0009] Furthermore, a rotating block is fixed on one side of the fixed frame close to the sieve chamber, and a rotating groove fixed on the sieve chamber is sleeved on the surface of the rotating block, a rotating shaft fixed on the inner wall of the rotating groove passes through the middle of the rotating block, and a torsion spring is wound on the surface of the rotating shaft, and the two side ends of the torsion spring are respectively abutted between the rotating shaft and the rotating block.

[0010] Furthermore, the clamps are all configured as arc-shaped plates, and the arc-shaped plates configured on the clamps match the curvature of the surface of the sieve cavity.

[0011] The beneficial effects of the utility model are:

[0012] 1. The positioning mechanism of the mobile screen is provided with a positioning block, a fixed frame, a rotating block, a rotating groove, a clamping plate, a rotating shaft and a torsion spring. When the operator presses the positioning block, the positioning block drives the rotating block to rotate on the surface of the rotating shaft through the fixed frame, and the rotating block squeezes the torsion spring to make the torsion spring elastically deformed, and the fixed frame drives the clamping plate to separate from the surface of the screen cavity. Then, the operator sets the pipeline on the surface of the screen cavity, and then the operator releases the positioning block, the elastic deformation of the torsion spring is restored, the torsion spring drives the fixed frame to move through the rotating block, and the fixed frame drives the clamping plate to clamp the pipeline on the surface of the screen cavity, and pre-fixes the pipeline on the screen cavity to prevent the pipeline from falling off the surface of the screen cavity, thereby improving the convenience of the operator in fixing the pipeline.

[0013] 2. The positioning mechanism of the mobile screen is provided with a ring, a slider and a slide groove. After the operator fits the positioning block and the surface of the screen cavity together, the operator pushes the ring, and the ring drives the slider to slide in the slide groove, so that the ring moves to the surface of the positioning block and fixes the position of the positioning block. This avoids the operator having to keep pressing the positioning block with his hand during the process of setting the pipe on the surface of the screen cavity, thereby improving the operator's usability.

[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are listed and described in detail with reference to the accompanying drawings.

[0025] Example:

[0026] See also Figure 1 - Figure 8A positioning mechanism for a mobile screen includes a mobile frame body 1 and a screen cavity 2, the screen cavity 2 is installed at the end of the mobile frame body 1, and a fixed frame 4 is symmetrically arranged at the end of the screen cavity 2, and the fixed frame 4 is rotatably connected to the screen cavity 2, and a rotating block 10 is welded on the side of the fixed frame 4 close to the screen cavity 2, and a rotating groove 11 welded on the surface of the rotating block 10 is sleeved, and a rotating shaft 14 welded on the inner wall of the rotating groove 11 passes through the middle of the rotating block 10, and a torsion spring 8 is wound on the surface of the rotating shaft 14, and the ends of both sides of the torsion spring 8 are respectively abutted between the rotating shaft 14 and the rotating block 10, and the two ends of the fixed frame 4 are respectively abutted between the rotating shaft 14 and the rotating block 10, and the fixed frame 4 is welded on both sides of the rotating shaft 14. The side ends are respectively welded with positioning blocks 7 and clamping plates 3, the clamping plates 3 and the surfaces of the sieve chamber 2 are mutually attached, and a plurality of sets of rulers 13 are welded on one side of the clamping plates 3 and the surfaces of the sieve chamber 2. When the operator needs to fix the pipeline on the sieve chamber 2, the operator first presses the positioning block 7. After the positioning block 7 is subjected to force, the positioning block 7 drives the fixing frame 4 to move. The fixing frame 4 uses the rotating block 10 as a support point, so that the fixing frame 4 drives the rotating block 10 to rotate on the surface of the rotating shaft 14, and the rotating block 10 rotates in the rotating groove 11. When the rotating block 10 rotates on the surface of the rotating shaft 14, the rotating block 10 squeezes the torsion spring 8. The torsion spring 8 is elastically deformed. After the torsion spring 8 is elastically deformed, the torsion spring 8 avoids the rotating block 10, so that the rotating block 10 can rotate on the surface of the rotating shaft 14. The fixing frame 4 drives the clamping plate 3 to move, and the clamping plate 3 is removed from the surface of the sieve cavity 2. Then the operator sets the pipe sleeve on the surface of the sieve cavity 2. When the operator sets the pipe sleeve on the surface of the sieve cavity 2, the operator releases the positioning block 7. After the positioning block 7 no longer squeezes the torsion spring 8 through the fixing frame 4, the torsion spring 8 is elastically deformed and restored. The torsion spring 8 pushes the rotating block 10 on the surface of the rotating shaft 14 The surface is rotated, so that the rotating block 10 drives the clamping plate 3 to move through the fixing frame 4, and the clamping plate 3 clamps the pipe on the surface of the sieve cavity 2, and pre-fixes the pipe on the sieve cavity 2, and a plurality of groups of rulers 13 are fixed on the inner wall of the clamping plate 3. When the clamping plate 3 drives the rulers 13 to clamp on the pipe, the rulers 13 increase the friction force of the clamping plate 3 on the surface of the pipe, and the pipe is clamped on the surface of the sieve cavity 2 by the clamping plate 3 to improve the stability. When the clamping plate 3 pre-fixes the pipe on the sieve cavity 2, the operator then uses tools such as binding ropes to fix the pipe on the sieve cavity 2, thereby improving the convenience of the operator in fixing the pipe.

[0027] In other embodiments, the surface of the sieve cavity 2 is symmetrically welded with a fixing block 6, and a slide groove 9 is opened in the middle of the fixing block 6, and a slider 12 is embedded in the slide groove 9, and a collar 5 sleeved on the surface of the sieve cavity 2 and the positioning block 7 is welded on the surface of the slider 12, and the cross-section of the positioning block 7 is set as a rectangular block, and the collar 5 sleeved on one side of the positioning block 7 is set as a rectangular groove, and the rectangular groove set on the surface of the positioning block 7 by the collar 5 matches the rectangular block set on the cross-section of the positioning block 7. When the operator presses the positioning block 7, the positioning block 7 drives the splint 3 to separate from the sieve cavity 2 through the fixing frame 4, and the operator first pulls the collar 5, The collar 5 drives the slider 12 to slide in the slide groove 9, so that the collar 5 slides on the surface of the sieve chamber 2, and then the operator presses the positioning block 7, and the positioning block 7 fits with the surface of the sieve chamber 2. Then the operator pushes the collar 5, and the collar 5 drives the slider 12 to slide in the slide groove 9, and moves the collar 5 to the surface of the positioning block 7, so that the collar 5 restricts the positioning block 7. When the position of the positioning block 7 is restricted, the positioning block 7 restricts the splint 3 through the fixing frame 4, so that the operator is prevented from putting the pipe on the surface of the sieve chamber 2. The operator no longer needs to press the positioning block 7 with his hand, thereby improving the usability of the operator.

[0028] In other embodiments, the collar 5 is configured to have a plurality of groups of wavy grooves. When the operator pulls the collar 5 to move, the operator places his hand on the collar 5. After the operator's hand is placed on the collar 5, the plurality of groups of wavy shapes on the surface of the collar 5 increase the friction force of the operator's hand on the surface of the collar 5, thereby improving the stability of the operator pulling the collar 5 to move.

[0029] In other embodiments, the splint 3 is configured as an arc-shaped plate, and the arc-shaped plate of the splint 3 matches the curvature of the surface of the sieve cavity 2. By matching the arc-shaped plate of the splint 3 with the curvature of the surface of the sieve cavity 2, the splint 3 can be sleeved on the surface of the sieve cavity 2, and the inner wall of the splint 3 fits with the surface of the sieve cavity 2, thereby increasing the stability of the splint 3 sleeved on the surface of the sieve cavity 2.
