Description

Technical Field

[0001] The utility model relates to the field of carpet production equipment, in particular to a positioning device for the production of composite block carpets. Background Art

[0002] Composite carpets are widely loved by people for their high cost performance and low price, and have a wide range of uses. They can be used in automotive interiors and house interiors. Different from traditional woven carpets, composite carpets are basically processed into large rolls first, and then cut into blocks of different sizes according to actual use, and then processed such as edge sealing to become finished carpets.

[0003] At present, when cutting composite carpets, it is necessary to position them, and then use lasers or cutters to cut them. Traditional cutting and positioning mechanisms mainly rely on manual positioning, which greatly depends on experience. The quality of the cut carpets is unstable and the error is large. When the existing cutting and positioning mechanisms are actually used, only the machine is used to press and cut the composite carpet. If the composite carpet shrinks, the cut products will be unqualified. Therefore, according to the above disadvantages, this application proposes a positioning device for the production of composite carpets. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose a positioning device for the production of composite block carpets.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A positioning device for the production of composite block carpets, including a frame and a chute. Both sides of the middle part of the frame are provided with beam frames. The beam frames are U-shaped with an opening downward. Both sides of the top of the beam frames are fixedly connected with electric push rods. The driving ends of the lower ends of the electric push rods are fixedly connected with driving blocks. Both sides of the driving blocks are rotatably connected with connecting rods. The ends of the connecting rods far away from the driving blocks are rotatably connected with connecting pieces. The inner sides of the connecting pieces are rotatably connected to both ends of a pressure roller. The outer sides of the connecting pieces are fixedly connected with reset blocks. Both sides of the top wall of the frame are provided with guide rails. Both sides inside the guide rails are slidably connected with sliders. The tops of the sliders are fixedly connected with limit moving columns. Adjusting grooves are arranged inside the limit moving columns. Springs are fixedly connected to the lower parts inside the adjusting grooves. The top ends of the springs are fixedly connected with the reset blocks. The reset blocks are slidably arranged inside the adjusting grooves;

[0006] Through the above technical solution, the composite carpet is sent to the lower part of the positioning mechanism by the conveyor belt on the rack. At this time, the electric push rod drives the connecting rod to move downward through the driving block. The connecting rod opens downward and makes the reset block move downward in the adjustment groove of the limit moving column through the connecting piece. At this time, the pressure roller presses downward on the surface of the composite carpet. Then, the servo motor drives the slider to drive the limit moving columns away from each other through the double-headed screw. At this time, the pressure rollers move away from each other, realizing the stretching and flattening of the composite carpet on the conveyor belt. While realizing the positioning of the composite carpet, it can be spread out, achieving the precision of cutting the composite carpet, ensuring that it is flat and the cutting is qualified at one time, and there are no defective products caused by wrinkled cutting.

[0007] As a further description of the above technical solution:

[0008] On both sides of the middle part of the top wall of the beam, cylinders are fixedly connected. The bottom ends of the cylinders are fixedly connected to both sides of the blade. A conveyor belt is arranged on the top of the rack, and the blade is arranged above the conveyor belt;

[0009] Through the above technical solution, the cylinder cuts the composite carpet unfolded on the conveyor belt.

[0010] As a further description of the above technical solution:

[0011] Limit slots are opened on both inner sides of the beam. Limit blocks are slidably connected in the limit slots. The closer ends of the limit blocks are fixedly connected to the farther ends of the driving block;

[0012] Through the above technical solution, when the driving block is driven by the electric push rod, the limit block slides in the limit slot, realizing the stable support of the beam for the driving block.

[0013] As a further description of the above technical solution:

[0014] Double-headed screws are rotatably connected in the sliding grooves. Both ends of the double-headed screws are threadedly connected to the sliders on both sides in the sliding grooves. The thread directions at both ends of the double-headed screws are opposite. One end of each double-headed screw penetrates through the guide rail and is connected to the driving end of the servo motor. The servo motors are fixedly connected to the outside of the guide rail;

[0015] Through the above technical solution, the servo motor drives the slider to slide in the sliding groove through the double-headed screw to cooperate with the electric push rod to push the movement of the pressure roller.

[0016] As a further description of the above technical solution:

[0017] The beam and the guide rail are perpendicular;

[0018] Through the above technical solution, the guide rail is used to support the movement of the limit moving column.

[0019] As a further description of the above technical solution:

[0020] The downward included angle between the two connecting rods on the driving block is 30 - 170 degrees;

[0021] Through the above technical solution, this included angle facilitates the electric push rod to drive the pressure roller.

[0022] The utility model has the following beneficial effects:

[0023] In the utility model, the electric push rod makes the connecting rod move downward through the driving block. The connecting rod opens downward and makes the reset block move downward in the adjustment groove of the limit moving column through the connecting piece. At this time, the pressure roller presses downward on the surface of the composite carpet. Then, the servo motor makes the slider drive the limit moving columns to move away from each other through the double-headed screw. At this time, the pressure rollers move away from each other, realizing the stretching and flattening of the composite carpet on the conveyor belt. While realizing the positioning of the composite carpet, it can be spread out, realizing the accuracy of the cutting of the composite carpet, ensuring that the cutting is qualified at one time and there are no defective products caused by wrinkled cutting. It does not rely on manual experience for positioning cutting, nor does it rely on simple mechanical extrusion for positioning cutting. Description of the Drawings

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Referring to Figures 1-3 , an embodiment provided by the present utility model: a positioning device for the production of composite block carpets, comprising a frame 3 and a chute 4. On both sides of the middle of the frame 3, there are beam frames 6. The beam frames 6 are U-shaped with an opening downward. On both sides of the top of the beam frames 6, electric push rods 8 are fixedly connected. The driving ends of the lower ends of the electric push rods 8 are fixedly connected with driving blocks 9. On both sides of the driving blocks 9, connecting rods 10 are rotatably connected. The ends of the connecting rods 10 far from the driving blocks 9 are rotatably connected with connecting members 19. The inner sides of the connecting members 19 are rotatably connected to both ends of a pressing roller 14. The outer sides of the connecting members 19 are fixedly connected with reset blocks 17. On both sides of the top wall of the frame 3, guide rails 20 are provided. On both sides inside the guide rails 20, sliding blocks 21 are slidably connected. On the tops of the sliding blocks 21, limiting moving columns 13 are fixedly connected. Inside the limiting moving columns 13, adjusting grooves 18 are provided. At the lower parts of the adjusting grooves 18, springs 16 are fixedly connected. The tops of the springs 16 are fixedly connected to the reset blocks 17. When the electric push rods 8 are reset, the springs 16 squeeze the reset blocks 17 to move the pressing roller 14 upward. The reset blocks 17 are all slidably arranged in the adjusting grooves 18. The composite carpet is sent into the lower part of the positioning mechanism by the conveyor belt 1 on the frame 3. At this time, the electric push rods 8 drive the driving blocks 9 to move the connecting rods 10 downward. The connecting rods 10 open downward and drive the reset blocks 17 to move downward in the adjusting grooves 18 of the limiting moving columns 13 through the connecting members 19. At this time, the pressing roller 14 presses downward on the surface of the composite carpet. Then, the servo motor 2 drives the sliding blocks 21 to drive the limiting moving columns 13 to move away from each other through the double-headed screw rod 15. At this time, the pressing rollers 14 move away from each other, realizing the stretching and flattening of the composite carpet on the conveyor belt 1. While realizing the positioning of the composite carpet, it can be spread out, realizing the precision of the cutting of the composite carpet, making it flat to ensure that the cutting is qualified at one time and no defective products caused by wrinkled cutting occur.

[0031] On both sides of the middle of the top wall of the beam frame 6, cylinders 11 are fixedly connected. The bottom ends of the cylinders 11 are fixedly connected to both sides of a blade 12. On the top of the frame 3, there is a conveyor belt 1. The blade 12 is arranged above the conveyor belt 1. The cylinder 11 cuts the composite carpet unfolded on the conveyor belt 1 with the blade 12.

[0032] On both sides of the inner sides of the beam frames 6, limiting grooves 5 are provided. Inside the limiting grooves 5, limiting blocks 7 are slidably connected. The ends of the limiting blocks 7 close to each other are fixedly connected to the ends of the driving blocks 9 far from each other. When the driving blocks 9 are driven by the electric push rods 8, the limiting blocks 7 slide in the limiting grooves 5, realizing the stable support of the beam frames 6 for the driving blocks 9.

[0033] A double-headed screw rod 15 is rotatably connected to each of the sliding grooves 4. Both ends of the double-headed screw rod 15 are threadedly connected to the sliders 21 on both sides inside the sliding grooves 4. The thread directions at both ends of the double-headed screw rod 15 are opposite. One end of the double-headed screw rod 15 penetrates through the guide rail 20 and is connected to the driving end of the servo motor 2. The servo motors 2 are fixedly connected to the outside of the guide rail 20. The servo motors 2 drive the sliders 21 to slide in the sliding grooves 4 through the double-headed screw rod 15 to cooperate with the electric push rod 8 to push the pressure roller 14 to move.

[0034] The beam 6 is perpendicular to the guide rail 20, and the guide rail 20 is used to support the movement of the limit moving column 13.

[0035] The downward included angle between the two connecting rods 10 on the driving block 9 is between 30° and 170°, and this included angle facilitates the electric push rod 8 to drive the pressure roller 14.

[0036] Working principle: During actual use, the conveyor belt 1 conveys the composite carpet to the lower part of the positioning mechanism. Then, the electric push rod 8 presses the connecting rod 10 through the driving block 9. The lower end of the connecting rod 10 squeezes the pressure roller 14 through the connecting piece 19. The pressure roller 14 moves downward in the limit moving column 13 through the reset block 17. The pressure roller 14 presses the composite carpet. At this time, the servo motor 2 drives the sliders 21 to slide in the sliding grooves 4 through the double-headed screw rod 15. The sliders 21 drive the limit moving columns 13 to move away from each other, so that the pressure roller 14 unfolds on the composite carpet. Then, the cylinder 11 cuts the composite carpet through the blade 12.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
