Description

Technical Field

[0001] This utility model relates to the field of composite plate processing technology, specifically a device for roughening the surface of prestressed composite plates. Background Technology

[0002] Prestressed composite slabs are widely used in the construction industry, and their surface roughness directly affects their bonding performance with other concrete structures. In existing technologies, surface roughening devices for composite slabs typically use blades or scribers with fixed spacing for surface treatment. However, this design has significant limitations: firstly, the fixed blade spacing makes it difficult to adjust, resulting in monotonous processing effects; secondly, the roughening device needs to be disassembled from the prestressed composite slab production line when not in use, which is time-consuming and labor-intensive. Therefore, there is an urgent need for a surface roughening device for composite slabs that can flexibly adjust the blade spacing and adapt to different processing requirements to improve construction efficiency and processing quality. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a device for roughening the surface of prestressed composite slabs, thus solving the technical problems mentioned in the background.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a device for roughening the surface of a prestressed composite slab, comprising a mounting frame, two shafts mounted on both sides of the mounting frame, and several positioning sleeves fitted on each of the two shafts, with a slitting plate installed at the bottom of the positioning sleeves; an adjustment and fixing structure is provided on one side of each of the two shafts; a lifting rod is provided at the lower position on the opposite side of each of the two shafts, and connecting plates are provided at both ends of the lifting rod to connect with the shaft.

[0007] Preferably, the adjusting and fixing structure includes a rotating plate and a locking bolt mounted on the rotating plate. The rotating plate is mounted on a shaft, and the locking bolt is equipped with two locking holes, which are respectively opened on the outer side wall of the mounting frame.

[0008] Preferably, the lifting rod is 5cm away from the vertically positioned swipe to provide space for the swipe to rotate and swing.

[0009] Preferably, threaded sleeves are provided on both sides of the shaft, and the threaded sleeves are connected to the threaded grooves on the shaft.

[0010] Preferably, the top of the slitting plate aligns with the groove on the bottom side of the positioning sleeve and is secured by bolts.

[0011] Preferably, the swivels on the two shafts are staggered.

[0012] Preferably, the bottom end of the slitting plate is an inclined surface.

[0013] (III) Beneficial Effects

[0014] The beneficial effects of this utility model are as follows:

[0015] This device for roughening the surface of prestressed composite slabs uses two shafts to support several scribbles. When a denser rough texture is required on the surface of the composite slab, the scribbles on both shafts can be adjusted to a vertical position. As the composite slab moves from the bottom of the scribbles on the two shafts, the bottom ends of the scribbles can pass over the surface of the composite slab to form a denser rough texture. When a larger gap in the rough texture is required, one shaft can be rotated, and the scribbles on that shaft can be lifted by a lifting rod. This allows only the scribbles on one shaft to pass over the surface of the composite slab, forming a larger gap in the rough texture. This allows for adjustments to be made according to the processing requirements of the prestressed composite slab to produce a rough texture of appropriate density on the surface of the prestressed composite slab.

[0016] This surface roughening device for prestressed composite slabs allows the shaft to be rotated when not in use by using a lifting rod on one side of the shaft. The lifting rod causes the slitting blade to swing upward and detach from the surface of the precast slab, preventing the slitting blade from contacting the slab material in the composite slab processing line. This allows the roughening device to be retracted when not needed, eliminating the need for frequent disassembly and effectively saving operating time and labor costs. Attached Figure Description

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. 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.

[0025] like Figure 1-6 As shown, this utility model provides a technical solution: a surface roughening device for prestressed composite slabs, including a mounting frame 1. The mounting frame 1 can be connected to an appropriate position on a prestressed composite slab processing production line, and is used to mount several scribing blades 4 on the upper side of the composite slab conveying production line. Two shafts 2 are mounted on both sides of the mounting frame 1, and several positioning sleeves 3 are fitted on each of the two shafts 2. Scribing blades 4 are mounted on the bottom end of the positioning sleeves 3. The bottom end of the scribing blades 4 is inclined. The scribing blades 4 on the two shafts 2 are staggered, which can avoid the scribing blades 4 on the bottom side of the two shafts 2 from repeatedly scribing lines on the surface of the composite slab. When processing dense rough textures, the scribing blades 4 on the two shafts 2 are adjusted to a vertical state. Figure 1 , Figure 4 and Figure 5 As shown, when the laminated plate passes under the scribe 4, the scribes 4 on the bottom sides of the two shafts 2 simultaneously create dense, rough textures on its surface. When machining with sparse, rough textures, rotating one side of the shaft 2 causes the lifting rod 9 to rotate with it, lifting the scribe 4 on that side to a state where it does not contact the laminated plate. Figure 2 As shown, only the slitting blade 4 on the bottom side of the other shaft 2 remains operational, forming a rough texture with larger intervals. Both sides of the shaft 2 are provided with threaded sleeves, which connect to the threaded grooves on the shaft 2. The threaded sleeves limit the position of several positioning sleeves 3 on the shaft 2, and by rotating the threaded sleeves on the shaft 2, the position of several positioning sleeves 3 on the shaft 2 can be finely adjusted to prevent the slitting blades 4 on the two shafts 2 from overlapping. The top of the slitting blade 4 aligns with the groove on the bottom side of the positioning sleeve 3 and is locked in place by bolts. Figure 6 As shown, this structure facilitates the separation or combination of the scriber 4 and the positioning sleeve 3, facilitates the replacement of the slide blade 4, and allows the scriber 4 at the part that overlaps with the skeleton on the surface of the laminated plate to be disassembled, such as... Figure 5As shown, to prevent the scribing blade 4 from rubbing against the skeleton, an adjustment and fixing structure is provided on one side of each of the two shafts 2. The adjustment and fixing structure includes a rotating plate 5 and a locking bolt 6 mounted on the rotating plate 5. The rotating plate 5 is mounted on the shaft 2, and the locking bolt 6 is equipped with two locking holes 7, which are located on the outer side wall of the mounting bracket 1, one above the other. When adjusting the shaft 2 by rotation, the locking bolt 6 is disconnected from the locking holes 7. At this time, the shaft 2 can be adjusted by rotation through the rotating plate 5. Figure 2 As shown, when the locking bolt 6 on the rotating plate 5 is connected to the locking hole 7 on the lower side, the lifting rod 9 on the shaft 2 can lift the scribing plate 4, thus retracting the scribing plate 4. When the locking bolt 6 on the rotating plate 5 is connected to the locking hole 7 on the upper side, the scribing plate 4 on the bottom side of the shaft 2 is in an upright state, allowing the scribing plate 4 to normally scratch rough textures on the surface of the composite plate. Adjusting the setting of the fixing structure allows for corresponding adjustments to the scribing tool 4 according to the processing requirements of the prestressed composite plate, processing rough textures of appropriate density on the surface of the prestressed composite plate. When it is not necessary to process rough textures, rotating the two shafts 2 and using the lifting rod 9 will swing all the scribing plates 4 upwards to the retracted state. Figure 3 As shown, by detaching the dicing blade 4 from the surface of the conveyor path of the composite plate in the processing production line to avoid contact, the dicing blade 4 can be stored without disassembling the entire device. This allows the roughing device to be stored away when not needed, eliminating the need for frequent disassembly and effectively saving operation time and labor costs.

[0026] Lifting rods 9 are provided on the lower side of the two shafts 2, and connecting plates 8 are provided at both ends of the lifting rods 9 to connect with the shafts 2. The lifting rods 9 are designed to lift the blades 4 when the shafts 2 are rotated. The lifting rods 9 are 5cm away from the vertically positioned scribing blades 4 to provide space for the rotation and swing of the scribing blades 4. The 5cm distance can prevent the scribing blades 4 from being unable to follow the movement of the stacked plate and tilting at a certain angle when the bottom of the scribing blades 4 contacts the surface of the stacked plate, thus ensuring that the scribing blades 4 can tilt at a certain angle as the stacked plate moves.

[0027] The operational steps for this application are as follows:

[0028] Fix the mounting bracket 1 at an appropriate position on the prestressed composite slab processing production line, and position the slitting plate 4 on the upper side of the composite slab conveying production line;

[0029] When machining dense, rough textures, adjust the slitting blades 4 on both shafts 2 to a vertical position. Figure 1 , Figure 4 and Figure 5 As shown, when the composite plate passes under the slitting plate 4, the slitting plates 4 on the bottom sides of the two shafts 2 simultaneously scratch dense rough textures on its surface.

[0030] When machining sparse, rough textures, rotating one side of the shaft 2 causes the lifting rod 9 to rotate along with the shaft 2. The lifting rod 9 then lifts the side sliding piece 4 until it no longer contacts the laminated plate. Figure 2 As shown, only the slitting blade 4 on the bottom side of the other shaft 2 is kept in operation, forming a rough texture with large intervals;

[0031] When rough textures are not required, rotate the two shafts 2, and use the lifting rod 9 to swing all the sliding pieces 4 upwards to the retracted position. Figure 3 As shown, by detaching the dicing blade 4 from the surface of the conveyor path of the laminated plate in the processing production line to avoid contact, the dicing blade 4 can be stored without disassembling the entire device. This allows the roughing device to be stored away when not needed, eliminating the need for frequent disassembly.

[0032] When adjusting the rotation of shaft 2, the locking bolt 6 is disconnected from the locking hole 7. At this time, the shaft 2 can be adjusted by rotating the plate 5. Figure 2 As shown, when the locking bolt 6 on the rotating plate 5 is connected to the locking hole 7 on the lower side, the lifting rod 9 on the shaft 2 can lift the slitting plate 4 to realize the storage of the slitting plate 4. When the locking bolt 6 on the rotating plate 5 is connected to the locking hole 7 on the upper side, the slitting plate 4 on the bottom side of the shaft 2 is in an upright state, so that the slitting plate 4 can normally scratch rough texture on the surface of the laminated plate.
