Description

Technical Field

[0001] This utility model relates to the technical field of carpet cutting devices, specifically an adjustable cutting device for carpet production. Background Technology

[0002] Carpet rerolling and slitting is a key process in carpet production or processing. It is mainly used to reroll large rolls of carpet and cut them into finished products of the required width or length. The slitting methods include: circular blade slitting, which is suitable for most synthetic fiber carpets and produces a smooth cut; and straight blade slitting, which is used for high-density or heavy carpets (such as wool carpets) and requires adjustment of blade pressure and speed.

[0003] The carpet rewinding and slitting machine is equipped with multiple sets of circular or straight blades, and the cutting width can be adjusted. However, when adjusting the position of the circular blades, it is necessary to first release the locking between the circular blade holder and the blade shaft, then adjust each circular blade holder to the required position, and then lock each circular blade holder in turn. The adjustment efficiency is low, and its operation efficiency needs to be optimized. Based on this, an adjustable cutting device for carpet production is provided. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable cutting device for carpet production in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable cutting device for carpet production, comprising a cutter shaft assembly and a circular cutter assembly. The cutter shaft assembly includes two semi-circular shafts, a convex telescopic chamber, a horizontal moving groove, and a threaded hole. The two semi-circular shafts are symmetrically fitted together to form the cutter shaft body. The convex telescopic chamber, the horizontal moving groove, and the threaded hole are sequentially and horizontally opened inside the semi-circular shafts and are interconnected. The top of the convex telescopic chamber extends to the top of the outer side of the semi-circular shaft, and the end of the threaded hole away from the horizontal moving groove extends to the outer end of the semi-circular shaft.

[0014] As a further embodiment of this utility model: multiple convex locking blocks are evenly arranged along the long side trajectory of the convex telescopic chamber, and the multiple convex locking blocks are sequentially attached and distributed.

[0015] The inner wall of the groove is fixed with a fixed tooth block. The top two ends of the convex locking block are inclined. Two adjacent convex locking blocks are formed by the inclined surfaces to form a slot for the fixed tooth block to be inserted, which is used to achieve the initial positioning of the tool holder.

[0016] As a further embodiment of this utility model: the locking unit includes an L-shaped compression seat and a screw;

[0017] The L-shaped extrusion seat is horizontally slidably connected to the inside of the horizontal moving groove and extends into the convex telescopic chamber. The bottom horizontal part of the L-shaped extrusion seat is inserted into the lower part of the lifting seat to provide extrusion and support for the lifting seat.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 In this embodiment of the present invention, an adjustable cutting device for carpet production includes a cutter shaft assembly 1 and a circular cutter assembly 2. The cutter shaft assembly 1 includes two semi-circular shafts 101, a convex telescopic chamber 102, a horizontal moving groove 103, and a threaded hole 104. The two semi-circular shafts 101 are symmetrically fitted together to form the cutter shaft body. The convex telescopic chamber 102, the horizontal moving groove 103, and the threaded hole 104 are sequentially opened horizontally inside the semi-circular shafts 101 and are interconnected. The top of the convex telescopic chamber 102 extends to the top of the outer side of the semi-circular shaft 101, and the end of the threaded hole 104 away from the horizontal moving groove 103 extends to the outer side of the semi-circular shaft 101.

[0032] The inner sides of the convex telescopic chamber 102, the horizontal moving groove 103, and the threaded hole 104 are provided with quick-lock components 3, which are used to realize the synchronous unlocking and locking operations of multiple circular knife components 2.

[0033] Quick-lock assembly 3 includes a limit unit and a locking unit;

[0034] The limiting unit is used to limit the rotation of the circular cutter assembly 2 and the cutter shaft assembly 1, and at the same time guides the movement of the circular cutter assembly 2 and initially limits the position of the circular cutter assembly 2.

[0035] The locking unit is used to reinforce and lock the limiting unit, thereby fixing the position of the circular knife assembly 2;

[0036] The limiting unit includes a lifting seat 301, a convex storage groove 302, a convex locking block 303, and a Z-shaped spring piece 304;

[0037] The lifting seat 301 is vertically slidably installed inside the convex telescopic chamber 102. The convex storage groove 302 is opened at the top of the lifting seat 301. The bottom of the convex locking block 303 is slidably connected to the inner side of the top groove of the convex storage groove 302. The top of the convex locking block 303 passes through the convex telescopic chamber 102 and protrudes to the outside of the semi-circular shaft 101.

[0038] Z-shaped spring 304 is fixed to the bottom of Z-shaped spring 304 and extends to the inner side of the bottom groove of convex storage groove 302;

[0039] The circular cutter assembly 2 includes a cutter holder 201, a circular cutter 202, and a sliding groove 203. The circular cutter 202 is fixed to the outside of the cutter holder 201, and the sliding groove 203 is opened on the inside of the cutter holder 201. The cutter holder 201 is sleeved on the outside of the cutter shaft composed of two semi-circular shafts 101 and slides through the sliding groove 203 to the part of the convex locking block 303 that protrudes from the outside of the semi-circular shaft 101, which is used to realize the rotation limit of the cutter holder 201 and the cutter shaft and the movement guide of the cutter holder 201.

[0040] Multiple convex locking blocks 303 are evenly arranged along the long side trajectory of the convex telescopic chamber 102, and the multiple convex locking blocks 303 are sequentially attached and distributed.

[0041] A fixing tooth block 204 is fixed to the top of the inner wall of the slide 203. The top two ends of the convex locking block 303 are inclined. Two adjacent convex locking blocks 303 form a slot for the fixing tooth block 204 to be inserted through the inclined surface, which is used to achieve the initial positioning of the tool holder 201.

[0042] The locking unit includes an L-shaped compression seat 305 and a screw 306;

[0043] The L-shaped extrusion seat 305 is horizontally slidably connected to the inside of the horizontal moving groove 103 and extends into the inside of the convex telescopic chamber 102. The bottom horizontal part of the L-shaped extrusion seat 305 is inserted into the lower part of the lifting seat 301 to provide extrusion and support for the lifting seat 301.

[0044] The screw 306 is threaded into the inside of the threaded hole 104 and extends into the horizontal moving groove 103. The screw 306 is rotatably connected to the vertical part of the L-shaped extrusion seat 305. The horizontal movement of the L-shaped extrusion seat 305 is achieved by turning the screw 306.

[0045] In this embodiment: When this cutting device is in use, two semi-circular shafts 101 are spliced ​​together to form the main body of the cutter shaft. The semi-circular shafts 101 have mounting holes for mounting the fixing bolts. When the circular cutter assembly 2 is sleeved on the outside of the cutter shaft body, by tightening the screw 306, the screw 306 moves into the horizontal moving groove 102 and pushes the L-shaped pressing seat 30 to press the lifting seat 301, so that the lifting seat 301 moves up to press the convex locking block 303. At this time, the convex locking block 303 cannot move down, and the fixing tooth block 204 on the cutter seat 201 is stuck between two adjacent convex locking blocks 303 and cannot move, thereby fixing the circular cutter assembly 2.

[0046] When it is necessary to adjust the cutting width of the carpet, the position of the circular blade assembly 2 needs to be adjusted. The operation method is as follows:

[0047] Insert a tool (such as a hex wrench) into the threaded hole 104 and engage it with the screw 306. Then loosen the screw 306. The screw 306 moves outward and drives the L-shaped compression seat 305 to move synchronously. The L-shaped compression seat 305 releases the compression on the lifting seat 301. At this time, the lifting seat 301 moves downward under the elastic force of multiple Z-shaped springs 304. That is, the bottom of the lifting seat 301 contacts the bottom of the inner wall of the convex telescopic groove 102. The lifting seat 301 releases the pressure on the convex locking block 303 (it should be noted that the Z-shaped springs 304 are always in a compressed state. At this time, the convex locking block 303 maintains a stable state of protruding outside the cutter shaft under the elastic force of the Z-shaped springs 304). At this time, the convex locking block 303 has a certain downward space, thus releasing the fixing and locking of multiple circular cutter assemblies 2.

[0048] Afterwards, the positions of multiple circular cutter assemblies 2 can be adjusted. When the circular cutter assembly 2 is adjusted to move horizontally, the fixed tooth block 204 will press the inclined surface of the convex locking block 303 to move downward, so that the fixed tooth block 204 can pass smoothly through the upper area of ​​the convex locking block 303. When the fixed tooth block 304 is located in the middle area of ​​the two convex locking blocks 303, the convex locking block 303 will be reset and moved upward under the elastic force of the new spring 304. This process is repeated. When the circular cutter assembly 2 is adjusted to the required position, the initial limiting of the circular cutter assembly 2 can be achieved.

[0049] After all the circular knife assembly 2 positions are adjusted, the screw 306 is tightened with a tool. The screw 306 pushes the L-shaped extrusion seat 305 to move. The L-shaped extrusion seat 305 extrudes the lifting seat 301 upward. The lifting seat 301 presses all the convex locking blocks 303, preventing the convex locking blocks 303 from moving downward. At this time, the convex locking blocks 303 and the fixed tooth block 304 are locked and fixed, thus ensuring the stability of the circular knife assembly 2 position.

[0050] The above operations allow for convenient adjustment of the circular blade assembly, further improving the efficiency of adjustment work during carpet processing.

[0051] Please refer to this carefully. Figures 1-4 The bottom of the lifting seat 301 near the L-shaped extrusion seat 305 has an inclined cut, and the height of the end of the lifting seat 301 away from the L-shaped extrusion seat 305 is less than the height of the large-size slot of the convex telescopic chamber 102.

[0052] The width of the lifting seat 301 matches the width of the large-size slot of the convex telescopic compartment 102. The bottom width and height of the convex locking block 303 match the top slot width and height of the convex storage slot 302. The top width of the convex locking block 303 matches the width of the small-size slot of the convex telescopic compartment 102.

[0053] In this embodiment: the inclined cut at the bottom of the lifting seat 301 facilitates the mutual contact and compression between the L-shaped compression seat 305 and the lifting seat 301. Under this compression force, the lifting seat 301 can move upward to press the convex locking block 303.

[0054] The height of the end of the lifting seat 301 away from the L-shaped extrusion seat 305 is less than the height of the large-size slot of the convex telescopic chamber 102, which provides space for the lifting seat 301 to move up and down.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
