Description

Technical Field

[0001] The utility model relates to the technical field of carpet production, in particular to a carpet conveying device. Background Art

[0002] After the carpet is processed, there is a step of cutting in the dicing machine. The carpet is usually fed into the cutting machine through a carpet conveyor. The traditional method is to convey the carpet through a chain. The chain conveying method is not only complex in structure, but also prone to slipping and wrinkling on the conveyor. In this case, it is necessary to manually correct and level it before entering the dicing machine. If the slipping and wrinkling are not found in time, the dicing will be carried out, resulting in a high defective rate. Therefore, it is very important to ensure that the carpet is flat and does not slip before entering the dicing machine. Utility Model Content

[0016] The technical scheme in the embodiment of the present invention will be described below in conjunction with the accompanying drawings in the embodiment of the present invention:

[0017] As shown in the figure, a carpet conveying device includes a device body 2, the device body 2 includes a frame 21, the frame 21 is provided with a fixed beam 22, one end of the fixed beam 22 is an active conveying roller 23, the opposite end is a driven roller 24, the active conveying roller 23 and the driven roller 24 are surrounded by a conveyor belt 25, a punching plate 26 is provided between the active conveying roller 23 and the driven roller 24, and the punching plate 26 is located above the fixed beam 22, the shaft of the active conveying roller 23 is connected to a servo motor 27, and the servo motor 27 is provided with a conveyor belt 25. The active conveying roller 23 rotates, and then the active conveying roller 23 drives the conveyor belt 25 to transmit. The punching plate 26 is evenly spaced with punching holes 28, which are arranged in a matrix. The conveyor belt 25 is evenly spaced with conveyor belt perforations 29, which are arranged in a matrix. On the one hand, the punching plate 26 provides support for the conveyor belt 25. On the other hand, the negative pressure device adsorbs the carpet on the conveyor belt 25 through the connection between the punching holes 28 and the conveyor belt perforations 29. Generally, the negative pressure device selects the negative pressure fan 1.

[0018] The density of the conveyor belt perforations 29 is greater than the density of the punching holes 28, which can form more fulcrums for the carpet, allowing the carpet to be more stably adsorbed by the negative pressure device; on the other hand, the area of ​​the conveyor belt perforations 29 can be made smaller than the punching holes 28. The conveyor belt perforations 29 are circular, and the punching holes 28 are annular. Multiple conveyor belt perforations 29 can be accommodated in the punching holes 28.

[0019] In another embodiment, the number of conveyor belt perforations 29 and punching holes 28 on the overlapping portion of the conveyor belt 25 and the punching plate 26 is the same, and each punching hole 28 corresponds to no less than three conveyor belt perforations 29, so that the force points formed are more uniform and stable.

[0020] Different carpets are transported by the conveying device of the utility model, and the required negative pressure is also different. Therefore, the negative pressure for lighter carpets can be smaller, while the negative pressure for heavier carpets needs to be adjusted to a larger value. Therefore, a sub-plate 3 is provided between the punching plate 26 and the fixed crossbeam 22. The sub-plate 3 is slidably connected relative to the punching plate 26, and the sub-plate 3 has the same structure as the punching plate 26; when the sub-plate 3 and the punching plate 26 are completely overlapped, the sub-plate punchings 31 of the sub-plate 3 and the punchings 28 are completely overlapped, and the negative pressure formed by the negative pressure device on the carpet is the largest at this time; when the sub-plate 3 slides relative to the punching plate 26, the area where the sub-plate punchings 31 and the punchings 28 overlap gradually shrinks, and the maximum displacement of the sub-plate 3 relative to the punching plate 26 should be smaller than the punchings 28. When the sliding displacement of the sub-plate 3 is the largest, the negative pressure formed by the negative pressure device on the carpet is the smallest, thereby realizing the demand for providing different negative pressures for different carpets.

[0021] The device of the utility model is located at the front end of a carpet cutter, and sometimes needs to wait for the cutter. In order to better fix and stabilize the carpet material during the waiting process, a roller 4 is arranged above the driven roller 24. The roller 4 includes a roller wall panel 41 and a pressure roller 42. The top of the pressure roller 42 is connected to the output end of the cylinder 43. The pressure roller 42 approaches or separates from the driven roller 24 through the extension and contraction of the cylinder 43. When the device body 2 needs to wait, the cylinder 43 is actuated to push the pressure roller 42 to move in the direction of the driven roller 24, so that the conveyed carpet material is fixed between the pressure roller 42 and the driven roller 24.

[0022] When in use, the carpet is placed on the conveyor belt 25. According to the negative pressure required by the carpet, the auxiliary board 3 is slid to a certain position, and the negative pressure fan 1 is started. The negative pressure formed by the negative pressure fan 1 causes the carpet to be adsorbed on the conveyor belt 25, and the carpet is moved forward by the conveyor belt 25 while being adsorbed. If it is necessary to wait for the cutter, the roller 4 is started; if it is not necessary to wait for the cutter, the roller 4 is not started.

[0023] The above embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of 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.
