Description

Technical Field

[0001] The utility model relates to the technical field of fabric pulling machines, and particularly relates to a rear-end feeding device for a fabric pulling machine with multi-layer synchronous fabric pulling. Background Art

[0002] A fabric pulling machine is a device that flattens a roll of fabric and lays it layer by layer. It mainly includes a laying bed, a feeding mechanism, a fabric pressing mechanism, and a fabric pulling mechanism. After the feeding mechanism conveys the fabric to the laying bed, the fabric pulling mechanism clamps and moves the fabric sent to the laying bed. After moving a set distance, the pulled fabric is cut so that the pulled fabric can be laid on the laying bed. Repeating this process can lay the flattened fabric layer by layer.

[0003] For example, the Chinese patent technical document with the publication number CN218402943U discloses an improved fabric pulling machine, which includes a fabric pulling machine bottom plate, a connection control component installed on the fabric pulling machine bottom plate, and a front-end feeding component connected to the connection control component; a matching guiding component is arranged outside the connection control component, a vertical adjustment and flattening component is arranged outside the connection control component, a rolling hair removal component is arranged above the fabric pulling machine bottom plate, an arc-shaped flattening outer arc plate is arranged inside the matching guiding component, an elastic member is arranged inside the flattening outer arc plate, and a sticky hair outer roller is arranged inside the rolling hair removal component. This fabric pulling machine can guide, adjust, and flatten the fabric according to the fabric pulling needs through the matching guiding component and the vertical adjustment and flattening component.

[0004] In the above technical solution, the rolling hair removal component can remove the hair on the fabric surface. However, in the above technical solution, the front-end feeding component uses a single fabric feeding roller, that is, when the fabric pulling mechanism pulls out the fabric on the fabric feeding roller and lays it on the laying bed, it can only be laid layer by layer, so there are certain limitations in the laying efficiency. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a rear-end feeding device for a fabric pulling machine with multi-layer synchronous fabric pulling, which can lay the fabric in double layers to improve the overall laying efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A rear-end feeding device for a fabric pulling machine with multi-layer synchronous fabric pulling, including a machine base, a fixed connection frame and a movable connection frame that can be translated are arranged on the machine base. The fixed connection frame and the movable connection frame are respectively used to connect a second fabric feeding roller and a first fabric feeding roller. A coupling guiding roller is arranged at the rear end of the machine base in the fabric pulling direction. The fabrics sent out by the first fabric feeding roller and the second fabric feeding roller overlap at the coupling guiding roller. A detection mechanism is arranged on the machine base, and the detection mechanism is used to detect whether there is a deviation between the fabrics sent out by the first fabric feeding roller and the second fabric feeding roller.

[0007] The present utility model is further configured such that: a horizontally arranged guide rod is provided on the machine base, a base is fixed to the bottom of the movable connection frame, the base is sleeved on the guide rod, and a sliding fit can be formed between the two.

[0008] The present utility model is further configured such that: a driving motor is provided on the machine base, a transmission gear is fixed to the output end of the driving motor, and a transmission rack that can mesh with the transmission gear is provided on the base.

[0009] The present utility model is further configured such that: the detection mechanism includes a first frame and a second frame fixed to the machine base. A first infrared sensor for detecting the distance from the fabric sent out by the first fabric feeding roller is provided on one side of the first frame, and a second infrared sensor for detecting the distance from the fabric sent out by the second fabric feeding roller is provided on one side of the second frame.

[0010] The present utility model is further configured such that: a first support guide roller and a second support guide roller are respectively provided on the first frame and the second frame, and the first support guide roller and the second support guide roller are respectively used to support the fabric sent out by the first fabric feeding roller and the second fabric feeding roller.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] Due to the provision of the first fabric feeding roller and the second fabric feeding roller, when pulling the fabric, the fabric is respectively fed into the coupling guide roller by the first fabric feeding roller and the second fabric feeding roller for overlapping. At this time, the downstream fabric pulling mechanism can pull and lay the overlapped fabric, so that the fabric can be laid in a double layer. Therefore, the technical problem in the prior art that the fabric can only be laid layer by layer is effectively solved, and the overall laying efficiency can be improved.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0018] As Figures 1 to 3 shown, the present utility model discloses a rear-end feeding device for a fabric pulling machine with multi-layer synchronous fabric pulling, which includes a machine base 1. A fixed connection frame 2 and a movable connection frame 3 capable of translating are provided on the machine base 1. The fixed connection frame 2 and the movable connection frame 3 are respectively used to connect a second fabric feeding roller 4 and a first fabric feeding roller 5. A coupling guiding roller 6 is provided at the rear end of the machine base 1 in the fabric pulling direction. The fabrics sent out by the first fabric feeding roller 5 and the second fabric feeding roller 4 coincide at the coupling guiding roller 6. A detection mechanism is provided on the machine base 1, and the detection mechanism is used to detect whether there is a deviation between the fabrics sent out by the first fabric feeding roller 5 and the second fabric feeding roller 4. When pulling the fabric, the fabrics are respectively sent into the coupling guiding roller 6 by the first fabric feeding roller 5 and the second fabric feeding roller 4 for coincidence. At this time, the downstream fabric pulling mechanism can pull and lay the coincided fabric, so as to be able to perform double-layer laying on the fabric, thereby improving the overall laying efficiency. When pulling the fabric, the fabrics are respectively sent into the coupling guiding roller 6 by the first fabric feeding roller 5 and the second fabric feeding roller 4 for coincidence. At this time, the downstream fabric pulling mechanism can pull and lay the coincided fabric, so as to be able to perform double-layer laying on the fabric, and further improve the overall laying efficiency;

[0019] When performing double-layer laying, first, the fabric specifications on the first fabric feeding roller 5 and the second fabric feeding roller 4 need to be the same. Second, a detection mechanism needs to be set up to ensure that the fabrics sent out by the first fabric feeding roller 5 and the second fabric feeding roller 4 can be aligned. Only in this way can the fabrics sent out by the first fabric feeding roller 5 and the second fabric feeding roller 4 coincide with each other after passing through the coupling guiding roller 6. If there is a deviation between the fabrics sent out by the first fabric feeding roller 5 and the second fabric feeding roller 4, it is necessary to drive the first fabric feeding roller 5 to move by translating the movable connection frame 3 to correct the fabric sent out by the first fabric feeding roller 5 in time.

[0020] In this embodiment, the structure that enables the movable connecting frame 3 to move is as follows: a horizontally arranged guide rod 7 is provided on the machine base 1. A base 8 is fixed to the bottom of the movable connecting frame 3. The base 8 is sleeved on the guide rod 7, and a sliding fit can be formed between the two. A driving motor 9 is provided on the machine base 1. A transmission gear 10 is fixed to the output end of the driving motor 9. A transmission rack 11 that can mesh with the transmission gear 10 is provided on the base 8. By driving the transmission gear 10 to rotate with the driving motor 9, the base 8 can be driven to move through the transmission rack 11 that meshes with the transmission gear 10, thereby driving the movement of the movable connecting frame 3. During the movement of the movable connecting frame 3, the base 8 can slide along the direction of the guide rod 7, thus guiding the movement of the base 8 and making the movement of the movable connecting frame 3 more stable.

[0021] In this embodiment, the specific structure of the detection mechanism includes a first frame 121 and a second frame 122 fixed to the machine base 1. A first infrared sensor 123 for detecting the distance from the fabric sent out by the first fabric feeding roller 5 is provided on one side of the first frame 121. A second infrared sensor 124 for detecting the distance from the fabric sent out by the second fabric feeding roller 4 is provided on one side of the second frame 122. The first infrared sensor 123, the second infrared sensor 124, and the driving motor 9 are all electrically connected to the PLC controller 100. A first signal is sent to the PLC controller 100 through the distance from the fabric sent out by the first fabric feeding roller 5 detected by the first infrared sensor 123. A second signal is sent to the PLC controller 100 through the distance from the fabric sent out by the second fabric feeding roller 4 detected by the second infrared sensor 124. In this way, the PLC controller 100 can compare the data corresponding to the first signal and the second signal in real time through a corresponding program. This calculation program is a common technology in the field of electrical automation technology, so it will not be elaborated here. When the parameters calculated by the comparison exceed the set range, a corresponding control signal is generated, so as to drive the driving motor 9 to rotate, drive the movable connecting frame 3 to move, and align the fabric sent out by the first fabric feeding roller 5 with the fabric sent out by the second fabric feeding roller 4.

[0022] In this embodiment, a first support guide roller 13 and a second support guide roller 14 are respectively provided on the first frame 121 and the second frame 122. The first support guide roller 13 and the second support guide roller 14 are respectively used to support the fabric sent out by the first fabric feeding roller 5 and the second fabric feeding roller 4, so as to prevent the fabric sent out by the first fabric feeding roller 5 and the fabric sent out by the second fabric feeding roller 4 from sagging, facilitating the first infrared sensor 123 and the second infrared sensor 124 to respectively sense the fabric sent out by the first fabric feeding roller 5 and the fabric sent out by the second fabric feeding roller 4.

[0023] This specific embodiment is only an interpretation of the present utility model, and it is not a limitation to the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
