Description
Technical Field
[0001] The utility model relates to the technical field of cutting devices, in particular to a positioning device for cutting automobile carpets. Background Art
[0002] Car carpet refers to the covering installed on the car floor, usually made of soft materials (such as fabric, rubber, etc.), used to protect the vehicle floor, while increasing comfort and aesthetics. In the production process of car carpet, it is often necessary to cut according to the specific model and size to adapt to the shape and size of the floor of different models. In order to ensure the accuracy and consistency of cutting, a positioning device is required to enable precise cutting.
[0003] An existing positioning device for cutting automobile carpets, when in use, has a pointed pressing plate arranged at the lower ends of two clamping plates, so that when clamping the carpet, the pointed tip at the lower end of the pointed pressing plate can be inserted into the surface of the carpet, thereby increasing the force points between the ground and the pointed pressing plate, so that the ground will not be displaced during cutting, thereby maintaining the efficiency of carpet cutting.
[0004] However, this method cannot handle the wrinkles on the carpet. If there are wrinkles on the carpet during cutting, the cutting line cannot be carried out along the predetermined trajectory, resulting in the shape of the cut carpet not meeting the design specifications. This inaccurate cutting will make it difficult for the carpet to fit the car floor perfectly, thus affecting the overall assembly effect and appearance. Due to inaccurate cutting, a new carpet needs to be cut to meet the design requirements, which will cause a waste of raw materials and increase production costs. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a positioning device for cutting a car carpet, comprising a frame 1, a motor 2 is fixedly connected to the front of the frame 1, a bidirectional screw rod 3 is fixedly connected to the output end of the motor 2, threaded sleeves 4 are threadedly connected to the outer sides of the bidirectional screw rod 3, a support rod 5 is fixedly connected to the rear of the threaded sleeve 4, a fixing frame 6 is fixedly connected to the rear of the support rod 5, a support rod 5 is fixedly connected to the rear of the fixing frame 6, a limiting assembly is fixedly connected to the other side of the rear support rod 5, the limiting assembly comprises a slider 16, the slider 16 is fixedly connected to one side of the support rod 5, the slider 16 is slidably connected to the outside of the slide rod 15, mounting plates 14 are fixedly connected to the two rear sides of the frame 1, and the slide rods 15 are fixedly connected to the opposite sides of the two mounting plates 14.
[0025] Start the motor 2, the output end of the motor 2 drives the bidirectional screw 3 to rotate, the rotation of the bidirectional screw 3 further drives the movement of the threaded sleeve 4, through the connection of the support rod 5, the movement of the threaded sleeve 4 can drive the movement of the fixed frame 6, with the movement of the fixed frame 6, the rear support rod 5 will also move accordingly, this movement makes the slider 16 slide outside the slide rod 15, the combination of the slider 16 and the slide rod 15 constitutes a sliding guide mechanism, which provides stable support and guidance for the movement of the fixed frame 6, under the joint action of the threaded sleeve 4 and the slider 16, the fixed frame 6 in the machine The upper part of the frame 1 moves back and forth. This back and forth movement allows the carpet to be evenly leveled, avoiding differences in leveling effects caused by uneven local force. While the fixed frame 6 moves, it also drives the hydraulic cylinder 7 and the pressure roller 9 to move together. The hydraulic cylinder 7 is a component that provides power, and its output end pushes the fixed frame 8 and the pressure roller 9 to move downward. This step is to ensure that the pressure roller 9 can fit tightly on the carpet, thereby achieving an effective leveling effect. When the pressure roller 9 contacts the carpet, the hydraulic cylinder 7 is closed. At this time, the pressure roller 9 will roll back and forth on the upper part of the carpet.
[0026] Reference Figure 2 and Figure 3 A hydraulic cylinder 7 is fixedly connected to the inside of the fixed frame 6, and a fixed frame 8 is fixedly connected to the output end of the hydraulic cylinder 7. A pressure roller 9 is rotatably connected to the inside of the fixed frame 8. Cylinders 10 are fixedly connected to both sides of the upper part of the fixed frame 6, and a pressure plate 11 is fixedly connected to the output end of the cylinder 10. Limiting columns 12 are slidably connected to both sides of the inside of the fixed frame 6, one end of the limiting column 12 is fixedly connected to the upper part of the pressure plate 11, and a buffer spring 13 is sleeved on the outside of the limiting column 12, one end of the buffer spring 13 is fixedly connected to the bottom of the fixed frame 6, and the other end of the buffer spring 13 is fixedly connected to the upper part of the pressure plate 11.
[0027] When the cylinder 10 is started, the output end of the cylinder 10 will quickly push the pressing plate 11 to move downward. As a component that directly contacts the carpet, the surface of the pressing plate 11 adopts an anti-slip design to ensure that it will not slide or shift when the carpet is pressed. As the pressing plate 11 moves, the limiting column 12 slides inside the fixing frame 6. The function of the limiting column 12 is to ensure the stability and directionality of the pressing plate 11 during the movement to prevent it from deviating from the predetermined track. At the same time, the limiting column 12 also plays a certain buffering role, reducing the impact of the pressing plate 11 on the fixing frame 6 during the movement. During the movement of the pressing plate 11, it will stretch or squeeze the buffer spring 13. The buffer spring 13 is set to reduce the impact force generated by the pressing plate 11 when pressing the carpet, thereby protecting the carpet from damage. At the same time, the elasticity of the buffer spring 13 also ensures that the pressing plate 11 can maintain a certain stability after pressing the carpet to prevent the carpet from loosening or shifting.

[0029] When the motor 2 19 is started, its output end starts working, driving the threaded rod 20 to rotate. The threaded rod 20 transmits power to the moving block 21 through its own rotation, and it moves with the rotation of the threaded rod 20. The limit block 22 ensures the stability and accuracy of the moving block 21 during the movement. The limit block 22 slides inside the limit groove 23 to ensure that the moving block 21 moves according to the predetermined trajectory. Under the precise guidance of the limit block 22, the moving block 21 not only moves itself, but also drives the fixed rod 24 and the motor frame 25 on its upper part to move together. The motor frame 25 is a component for fixing the cutting knife 27. It drives the cutting knife 27 to move back and forth inside the frame 1 as the moving block 21 moves, and the motor 3 26 is started.

When the pressure roller 9 contacts the carpet, the hydraulic cylinder 7 is closed, so that the pressure roller 9 rolls back and forth on the upper part of the carpet to level the carpet, thereby effectively leveling the carpet and ensuring that the carpet is completely flat during the cutting process. It can minimize cutting errors and reduce the need to re-cut or replace carpets. It ensures that the cutting lines are accurate, reduces the waste of raw materials, and reduces production costs. When the carpet is leveled, the two The first fixing frame 6 is moved to both sides of the carpet, and the cylinder 10 is started. The output end of the cylinder 10 pushes the pressing plate 11 to move downward. The pressing plate 11 moves and drives the limiting column 12 to slide inside the fixing frame 6. When the pressing plate 11 moves, it stretches or squeezes the buffer spring 13. Under the action of the pressing plate 11, the carpet is pressed and fixed. Then the motor 2 19 is started. The output end of the motor 2 19 drives the threaded rod 20 to rotate. The threaded rod 20 drives the moving block 21 to move.
