Description

Technical Field

[0001] This utility model relates to the field of block cutting, and in particular to a block cutting device with a positioning structure. Background Technology

[0002] Block cutting equipment is a specialized device for cutting blocks into specific dimensions. It achieves precise cutting through various structural designs and working principles. For example, frame-type sawing machines use hydraulic drive to flip the block before performing longitudinal and transverse cutting. Multi-unit collaborative cutting devices improve automation efficiency through multiple cutting units and transfer devices. Devices with dust collection functions can collect dust during cutting to ensure a safe operating environment. Aerated concrete block cutting units use flipping hangers and longitudinal and transverse cutting devices to achieve high-precision cutting. Some devices, such as rotary blade cutting devices, can also improve the smoothness of the cut surface through special design. These devices are widely used in the building materials production field, enabling efficient, precise, and environmentally friendly cutting operations according to different block types and production needs. They are key equipment for ensuring that block products meet building requirements.

[0003] In the prior art, compared with the Chinese utility model with announcement number CN214925906U, a block cutting device is disclosed, which cuts the block from multiple directions to ensure the cutting effect. However, in actual operation, it was found that although the block itself is relatively brittle, it is still composed of concrete. If it is not effectively positioned and clamped during the cutting process, the blade is prone to vibration, and the cut surface cannot be guaranteed to be flat. In addition, the working efficiency is not high when using the reciprocating cutting method. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-7As shown, a block cutting device with a positioning structure includes a dust removal mechanism 1 for dust removal and a cutting mechanism 2 for providing cutting power. The dust removal mechanism 1 is installed outside the cutting mechanism 2. It also includes a bottom positioning mechanism 5 for positioning the block and a conveying mechanism 4 for moving the bottom positioning mechanism 5, as well as a cooperating mechanism 3 for cooperating the bottom positioning mechanism 5 and the conveying mechanism 4. The conveying mechanism 4 is installed on the lower side of the cutting mechanism 2. The bottom positioning mechanism 5 is slidably connected to the upper end of the conveying mechanism 4, and the bottom of the bottom positioning mechanism 5 cooperates with the conveying mechanism 4 through the cooperating mechanism 3 to drive the block to move for cutting.

[0033] The conveying mechanism 4 includes a sprocket 41, a chain 42, and a support rail 43. The chain 42 is mounted on the sprocket 41, and the upper ends of both sides of the chain 42 are provided with support rails 43. The top of the support rails 43 is fitted with a support wheel 44, which is mounted on the conveying frame 51 of the bottom positioning mechanism 5.

[0034] The bottom positioning mechanism 5 includes a conveyor frame 51, a positioning plate on the rear side of the conveyor frame 51, and a clamping plate 52 on the front side of the conveyor frame 51. The bottom of the clamping plate 52 is slidably connected to the conveyor frame 51 via a slide block 53. The slide block 53 cooperates with a fixing plate 54 via an elastic traction component. The fixing plate 54 is fixedly mounted on the conveyor frame 51.

[0035] The cooperating mechanism 3 includes a limiting guide rail 31, a claw 32, and an inner retractable clamping plate 33. The two inner retractable clamping plates 33 are slidably connected to the bottom surface of the conveyor frame 51. The inner side of the inner retractable clamping plate 33 is connected to the elastic traction component through the transmission component. The bottom of the conveyor frame 51 is connected to the claw 32 through the locking rod 321. The claw 32 is fixed to the chain 42. The outer side of the inner retractable clamping plate 33 is provided with a limiting guide rail 31 for driving the inner retractable clamping plate 33 to clamp.

[0036] In this embodiment, the transmission assembly includes a transmission shaft 34, a rack 35, and a gear 36. A rack 35 is provided on the inner side of each of the two inward-shrinking clamping plates 33, and a gear 36 is provided between the two racks 35. The gear 36 is connected to the elastic traction assembly at the top through the transmission shaft 34. When the limiting guide rails 31 on both sides limit the inward-shrinking clamping plates 33, causing the inward-shrinking clamping plates 33 to shrink and clamp, the rack 35 cooperates with the gear 36 to make the gear 36 and the transmission shaft 34 rotate.

[0037] In this embodiment, the elastic traction assembly includes a return spring 37, a pull plate 38, a pre-tensioning spring plate 39, and a tightening wheel 310. The top of the drive shaft 34 is connected to the tightening wheel 310. A tightening rope 311 is wound around the outside of the tightening wheel 310. One end of the tightening rope 311 is fixed to the tightening wheel 310, and the other end of the tightening rope 311 passes through the fixing plate 54 and connects to the pull plate 38 located inside the slide block 53. A return spring 37 is provided between the fixing plate 54 and the slide block 53. The pull plate 38 is located at the center inside the slide block 53. Pre-tensioning spring plates 39 are provided on both the front and rear sides of the pull plate 38. The pull plate 38 and the pre-tensioning spring plates 39 provide elastic clamping for the clamping plate 52. A gap is provided between the pre-tensioning spring plates 39 and the clamping plate 52 to avoid excessive clamping force on the block and damage to the block.

[0038] In this embodiment, two pre-tensioning spring plates 39 are provided on both the front and rear sides, and the pre-tensioning spring plates 39 are arc-shaped spring plates.

[0039] In this embodiment, the locking rod 321 is fixed to the rack 35. The initial position of the locking rod 321 does not overlap with the position of the claw 32. When the inward clamping plate 33 drives the locking rod 321 to tighten, the locking rod 321 and the claw 32 overlap. Only when the inward clamping plate 33 drives the rack 35 and the locking rod 321 to retract can the claw 32 and the locking rod 321 cooperate with each other, thereby pulling the conveyor frame 51 and the block fixed at the upper end. Otherwise, the conveyor frame 51 will not be pulled, thus improving the flexibility of the device.

[0040] In this embodiment, the claw 32 has a hook groove formed on the end face of the locking rod 321, and the hook groove area of ​​the locking rod 321 corresponding to the claw 32 is a cylindrical structure.

[0041] In this embodiment, a top positioning mechanism 6 is provided at the upper end of the bottom positioning mechanism 5. The top positioning mechanism 6 includes a top limiting slide rail 61, a top positioning rocker 62, a pressure roller 63, and a top positioning block 64. The front end of the conveyor frame 51 is connected to the top positioning rocker 62 through a spring shaft. A pressure roller 63 is provided at the top of the center position of the top positioning rocker 62. A top positioning block 64 is provided at the end of the top positioning rocker 62 corresponding to the block end. A top limiting slide rail 61 is installed on the dust removal mechanism 1 to restrict the rotation of the top positioning rocker 62.

[0042] Working principle: Start the motor of the cutting mechanism 2 to drive the cutting blade 21 to rotate. At this time, place the conveyor frame 51 on the support slide rail 43 and place the block between the fixed plate and the clamping plate 52. Push the clamping plate 52 forward. The weight of the conveyor frame 51 and the block causes it to be subjected to inertial force. At this time, the opening of the limit guide rail 31 gradually applies pressure to the inward clamping plate 33. The inward clamping plate 33 and the rack 35 begin to retract. After the inward clamping plate 33 and the rack 35 retract, the locking rod 321 moves from the outside to the center. At this time, the pawl 32 locks the locking rod 321 and continues to drive the locking rod 321 and the upper conveyor frame 51 to move.

[0043] When the locking bar 321 is engaged and moved, the pawl 32 begins to drive the conveyor frame 51 to move as a whole. At this time, the inner clamping plate 33 continues to be clamped by the limit guide rails 31 on both sides. The rack 35 and the gear 36 cooperate to make the drive shaft 34 rotate. The drive shaft 34 transmits the rotational force to the tightening wheel 310. The tightening wheel 310 begins to wind up the tightening rope 311. The tightening rope 311 drives the pull plate 38 and the clamping plate 52, so that the clamping plate 52 cooperates with the conveyor frame 51 to clamp the block. And because the pull plate 38 is elastically supported by the pre-tightening spring plate 39, the clamping plate 52 only ensures clamping and will not crush the block.

[0044] At the same time, the pressure roller 63 on the top of the top positioning rocker 62 on the conveyor frame 51 is gradually pressed by the top limiting slide rail 61, and the elastic top positioning block 64 on the top positioning rocker 62 also clamps and positions the top of the block, thus ensuring that the block will not shake when it is cut with the cutting blade 21, resulting in a neater surface and more standard dimensions.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
