Description

Technical Field

[0001] This utility model relates to the field of electric grinding machine technology, and in particular to an electric plaster line splicing grinding machine. Background Technology

[0002] Plaster moldings are widely used in building decoration, and demand is increasing. Sanding is a crucial step in their production, as it removes burrs and bumps that may remain after molding to ensure quality. Existing sanding equipment falls into two categories: manual sanding equipment and semi-automatic or partially automated sanding equipment.

[0003] Currently, most of the grinding devices used in the production of plaster moldings are equipped with grinding heads of fixed shapes such as spherical or flat. However, it is difficult to fully adapt the grinding heads to the various shapes of plaster moldings, resulting in low grinding efficiency. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an electric plaster line splicing and grinding machine, which aims to improve the problem of low grinding efficiency caused by the grinding head of the grinding device currently used in plaster line production when facing plaster lines of various shapes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electric plaster line splicing and grinding machine, comprising a housing, a sliding structure fixedly connected to the inner wall of the housing, a sliding plate one slidably connected to the inner wall of the housing, a connecting block symmetrically fixedly connected to one side of the sliding plate one, a sliding plate two fixedly connected to one side of the connecting block, a limiting structure fixedly connected to one side of the sliding plate two, a limiting cylinder uniformly fixedly connected to one side of the limiting structure, a limiting spring two fixedly connected to the inner wall of the limiting cylinder, a sliding rod fixedly connected to one end of the limiting spring two, a positioning strip fixedly connected to one end of the sliding rod, a connecting rod two symmetrically fixedly connected to one end of the positioning strip, and a limiting spike fixedly connected to one end of the connecting rod two.

[0006] By adopting the above technical solution, the box body drives the front positioning structure to make each positioning strip fit into the concave and convex parts of the plaster line. The connecting rod 2 and the limiting spikes connected to it move backward to different degrees, thereby adapting to plaster lines of different shapes. The sliding rod connected to the positioning strip moves backward to different degrees, allowing the sliding rod to slide to different degrees in the limiting cylinder. Through the limiting structure, the limiting spikes are inserted into the fixed plate to fix the position of each sliding rod and positioning strip. Sandpaper is pasted on the curved surface formed by the connection of each positioning strip. The internal sliding structure of the box body is activated to make the sliding plate 1 move left and right periodically, so that the sandpaper pasted on the positioning strip polishes the plaster line. This improves the problem of low polishing efficiency of the polishing head of the polishing device used in the current production of plaster lines when facing plaster lines of different shapes.

[0007] Preferably, the sliding structure includes a motor, one side of which is fixedly connected to the inner wall of the housing, and the output end of the motor is fixedly connected to a rotating shaft.

[0008] Preferably, one end of the rotating shaft is fixedly connected to an eccentric wheel, one side of the eccentric wheel is rotatably connected to a rocker arm, and one side of the rocker arm is rotatably connected to one side of the sliding plate.

[0009] Preferably, the limiting structure includes a connecting rod one and a connecting rod four. Both ends of the connecting rod one and both ends of the connecting rod four are fixedly connected to sliding strips. The inner walls of the sliding strips are symmetrically fixedly connected to limiting springs one. One end of the limiting spring one is fixedly connected to a fixing plate, and one side of the fixing plate is fixedly connected to a limiting plate.

[0010] Preferably, a sliding block is fixedly connected to the top of the limiting plate, and the outer wall of the sliding block is slidably connected to one side of the sliding strip.

[0011] Preferably, a limiting spring three is fixedly connected to the inner wall of the sliding bar, and a limiting block is fixedly connected to the top end of the limiting spring three.

[0012] Preferably, one side of the fixed plate is slidably connected to one side of the sliding plate two, and one side of the connecting rod one is fixedly connected to one side of the sliding plate two.

[0013] Preferably, the outer wall of the limiting block is slidably connected to the inner wall of the sliding strip, and a connecting rod three is fixedly connected to the bottom of the limiting block, with the outer wall of the connecting rod three slidably connected to the inside of the sliding strip.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by pushing the box body to drive the front positioning structure, each positioning strip is made to fit into the concave and convex parts of the plaster line. The connecting rod and the limiting spike connected to it move backward to different degrees, thereby adapting to plaster lines of different shapes. The positioning strip causes the sliding rod to slide to different degrees in the limiting cylinder. The limiting structure fixes the position of each sliding rod and positioning strip. Sandpaper is attached to the curved surface formed by the positioning strips. The sliding structure allows the sandpaper to polish the plaster line, improving the polishing efficiency.

[0015] In this invention, the starting motor drives the rotating shaft to rotate, which in turn drives the rocker arm to move, causing the sliding plate one to move left and right periodically in the slot opened in the housing, which in turn drives the connecting block, the sliding plate two, and the front structures to move left and right periodically.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-7An embodiment of this utility model provides an electric plaster line splicing and grinding machine, comprising a housing 1, a sliding structure fixedly connected to the inner wall of the housing 1, a sliding plate 2 slidably connected to the inner wall of the housing 1, a connecting block 3 symmetrically fixedly connected to one side of the sliding plate 2, a sliding plate 4 fixedly connected to one side of the connecting block 3, a limiting structure fixedly connected to one side of the sliding plate 4, a limiting cylinder 12 uniformly fixedly connected to one side of the limiting structure, a limiting spring 18 fixedly connected to the inner wall of the limiting cylinder 12, a sliding rod 13 fixedly connected to one end of the limiting spring 18, a positioning strip 17 fixedly connected to one end of the sliding rod 13, a connecting rod 10 symmetrically fixedly connected to one end of the positioning strip 17, and a limiting spike 11 fixedly connected to one end of the connecting rod 10.

[0020] Specifically, the limiting structure separates the limiting spike 11 from the fixed plate 8. The sliding rod 13 and the positioning strip 17 are pushed forward to return to their original positions by the restoring force of the limiting spring 18. This pushes the housing 1 to drive the front positioning structure, causing each positioning strip 17 to fit into the concave and convex parts of the plaster line. The connecting rod 10 and the limiting spike 11 connected to them move backward to different degrees, thus adapting to plaster lines of different shapes. The sliding rod 13 connected to the positioning strip 17 moves backward to different degrees, compressing the limiting spring 18, causing the sliding rod 13 to slide to different degrees within the limiting cylinder 12. By using a limiting structure, the limiting spikes 11 are inserted into the fixed plate 8 to fix the positions of each sliding rod 13 and positioning strip 17. Sandpaper is pasted on the curved surface formed by the connection of each positioning strip 17. The internal sliding structure of the housing 1 is activated to make the sliding plate 2 move left and right periodically, which in turn drives the connecting block 3, the sliding plate 4, and each positioning strip 17 to move left and right periodically. This enables the sandpaper pasted on the positioning strip 17 to polish the plaster line, which improves the problem of low polishing efficiency caused by the polishing head of the polishing device used in the current production of plaster lines when facing plaster lines with different shapes.

[0021] Reference Figure 5 , Figure 7 The sliding structure includes a motor 23, which is fixedly connected to the inner wall of the housing 1. The output end of the motor 23 is fixedly connected to a rotating shaft 21. One end of the rotating shaft 21 is fixedly connected to an eccentric wheel 22. One side of the eccentric wheel 22 is rotatably connected to a rocker arm 24. One side of the rocker arm 24 is rotatably connected to one side of the sliding plate 2.

[0022] Specifically, the starting motor 23 drives the rotating shaft 21 to rotate, which in turn drives the rocker arm 24 to move, causing the sliding plate 2 to move left and right periodically in the slot opened in the housing 1, which in turn drives the connecting block 3, the sliding plate 4, and the front structures to move left and right periodically.

[0023] Reference Figure 3 , Figure 4 , Figure 6The limiting structure includes connecting rod 1 5 and connecting rod 4 16. Both ends of connecting rod 1 5 and both ends of connecting rod 4 16 are fixedly connected to sliding bars 6. Limiting spring 1 14 is symmetrically fixedly connected to the inner wall of sliding bar 6. One end of limiting spring 1 14 is fixedly connected to a fixing plate 8. One side of fixing plate 8 is fixedly connected to a limiting plate 9. The top of limiting plate 9 is fixedly connected to a sliding block 7. The outer wall of sliding block 7 is slidably connected to one side of sliding bar 6. The inner wall of sliding bar 6 is fixedly connected to a limiting spring 3 19. The top end of limiting spring 3 19 is fixedly connected to a limiting block 20. One side of fixing plate 8 is slidably connected to one side of sliding plate 2 4. One side of connecting rod 1 5 is fixedly connected to one side of sliding plate 2 4. The outer wall of limiting block 20 is slidably connected to the inner wall of sliding bar 6. The bottom of limiting block 20 is fixedly connected to a connecting rod 3 15. The outer wall of connecting rod 3 15 is slidably connected to the inside of sliding bar 6.

[0024] Specifically, the fixed plate 8 is slid to a suitable position so that the limiting spike 11 inserts into the limiting plate 9. The limiting spring 14 inside the sliding strip 6 contracts. When the sliding block 7 at the top of the limiting plate 9 slides on the sliding strip 6, it will press the limiting block 20 into the inner wall of the sliding strip 6 through the inclined surface on the limiting block 20. The limiting spring 3 19 at the bottom of the limiting block 20 contracts, and the connecting rod 3 15 slides down accordingly. After sliding to a suitable position, the limiting block 20 is engaged in the groove of the sliding block 7 by the restoring elasticity of the limiting spring 3 19, thus closing the limiting structure. Pulling the connecting rod 3 15 down compresses the limiting spring 3 19, causing the limiting block 20 to move downward. The sliding block 7 loses its engagement and is pushed outward by the restoring elasticity of the limiting spring 14, releasing the limitation on the limiting plate 9 and the limiting spike 11, thereby allowing the positioning strip 17 to adapt to plaster lines of different sizes.

[0025] Working principle: During use, pulling down the connecting rod 15 causes the limiting block 20 to move downwards, separating the limiting spike 11 from the fixed plate 8. The sliding rod 13 and positioning strip 17 return to their original positions, pushing the housing 1 to move the front positioning structure so that each positioning strip 17 fits into the concave and convex parts of the plaster line. The connecting rod 10 and the limiting spike 11 then move backwards to varying degrees, pushing the two fixed plates 8 so that the limiting spike 11 inserts into the rubber limiting plate 9. The limiting spring 14 inside the sliding strip 6 contracts, and the sliding... The sliding block 7 causes the limiting block 20 to engage with the groove of the sliding block 7, thereby limiting the position of the fixed plate 8 and the limiting plate 9. The limiting spike 11 is inserted into the fixed plate 8, and the sliding rod 13 and the positioning strip 17 are fixed in position. Sandpaper is pasted on the curved surface formed by the connection of each positioning strip 17. The motor 23 is started to drive the rocker arm 24 to move, so that the sliding plate 2 moves left and right periodically in the groove opened in the housing 1, and the positioning strip 17 moves left and right periodically, so that the sandpaper pasted on the positioning strip 17 can polish the plaster line.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
