Description

Technical Field

[0001] The utility model relates to the technical field of automatic edge binding machines, and particularly relates to a pressing structure of an automatic edge binding machine. Background Technique

[0002] Most of the existing edge binding devices for blanket production adopt the method of manually moving the blanket for edge binding processing inside the machine case. For the existing edge binding devices for blanket production, it is necessary to manually align the blanket edge with the sewing part of the edge binding device. It is very dangerous when the hand is too close, and the situation of accidental touch is likely to occur.

[0003] The existing automatic edge binding machine transports and moves the carpet continuously by using multiple electric rollers, so that the carpet moves from one end to the other end of the edge binding machine, avoiding manual intervention. However, there is a lack of extrusion and fixation on the edge binding part of the carpet on the side of the edge binding machine. When the carpet starts to be edge bound, since the other end is not wound up, the carpet lacks strong pulling force during edge binding at this time, and thus cannot be straightened. As a result, the carpet still needs to be manually pulled at this time to ensure no wrinkles during edge binding until the carpet can be wound around the winding device. The existing automatic edge binding machine has a long production line, and the area of the carpet processed by the automatic edge binding machine is usually large, resulting in it being too troublesome, time-consuming and laborious to manually pull the whole process at the initial stage of processing to ensure straightening.

[0004] A pressing structure of an automatic edge binding machine is proposed to solve the problems mentioned above. Content of the Utility Model

[0005] The purpose of the utility model is to provide a pressing structure of an automatic edge binding machine to solve the problem that when the carpet starts to be edge bound, since one end of the carpet is not wound up, the carpet lacks strong pulling force during edge binding at this time, and thus cannot be straightened. As a result, the carpet still needs to be manually pulled at this time to ensure no wrinkles during edge binding until the carpet can be wound around the winding device. The area of the carpet that needs to use the automatic edge binding machine is usually large, so it is too troublesome to manually pull the whole process to ensure straightening.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A pressing structure of an automatic edge binding machine, including a carpet supporting table, a plurality of lifting rollers are rotatably connected to the top surface of the carpet supporting table, a carpet body is lapped on the lifting rollers, and an edge binding device is installed on one side of the carpet supporting table;

[0007] Pressing components located above the carpet supporting table are arranged on both sides of the edge binding device. The pressing component includes a mechanical bin housing symmetrically fixed on the outside of the carpet supporting table. A motor bin is fixedly installed at the bottom of the mechanical bin housing. A driving motor is fixedly connected inside the motor bin. The output end of the driving motor extends into the mechanical bin housing and is fixedly connected to a threaded rod. The top end of the threaded rod is rotatably connected to the mechanical bin housing.

[0008] Preferably, a threaded sleeve is slidably connected to the external thread of the threaded rod, and a lifting rod is fixedly connected to the outside of the threaded sleeve.

[0009] Preferably, the top end of the lifting rod slidably penetrates through the mechanical bin housing and is fixedly connected to a fixing frame, and a flipping assembly is arranged above the fixing frame.

[0010] Preferably, the flipping assembly includes an adjustment bin fixed to the outside of one fixing frame, a first motor is installed inside the adjustment bin, and a connecting plate is fixedly connected to the output end of the first motor.

[0011] Preferably, a rotating roller shaft is snap-fitted to the connecting plate, the other end of the rotating roller shaft is rotatably connected to a rotating plate, and the rotating plate is rotatably connected to the fixing frame on the other side.

[0012] Preferably, through holes are formed in the rotating roller shaft, the connecting plate and the through holes are penetrated by inserting rods, one end of the inserting rod is fixedly connected to a docking head, a fixing cap is installed outside the docking head, and clamping columns are symmetrically slidably connected to both sides of the fixing cap.

[0013] Preferably, a clamping block is fixedly connected to one end of the clamping column, a pulling ring is fixedly connected to the other end of the clamping column, a first spring is fixedly connected to the side of the pulling ring, the first spring is sleeved outside the clamping column, and the clamping block is snap-fitted to the docking head.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the pressing structure of the automatic edge-locking machine, the carpet can be pressed against the lifting roller by the rotating roller shaft, and in cooperation with the first motor with differential speed setting, the subsequent carpet can always be kept in a straightened state during processing, avoiding manual pulling or pressing of the carpet at the initial stage, and eliminating the need for manual long-term pulling of the carpet to ensure that the carpet is straightened. The specific content is as follows:

[0015] 1. By starting the driving motor, the threaded rod drives the threaded sleeve to move vertically, so that the lifting rod drives the height of the fixing frame to change. Finally, the rotating roller shaft can press the carpet against the lifting roller. Then, through the first motor, one rotating roller shaft can stably and uniformly feed the carpet into the edge-locking device, and by setting a speed difference between the set speeds of the two rotating roller shafts, the subsequent carpet can always be kept in a straightened state during processing, avoiding manual pulling or pressing of the carpet at the initial stage, and eliminating the need for manual long-term pulling of the carpet to ensure that the carpet is straightened.

[0016] 2. By pulling the pull ring, the engaging block is disengaged from the docking head, thereby removing the fixing cap, and then the insertion rod can be removed. Then, one end of the rotating roller shaft can be turned upward, and then the carpet can be directly turned over, so that the other side of the carpet can be continuously edge-locked. By cooperating with the replacement of equipment or the color of the thread used for edge-locking, the thread colors during carpet edge-locking can be distributed in a staggered manner in multiple colors, increasing the aesthetics of the carpet. Moreover, it is convenient to directly turn over the carpet when the edge-locking is halfway through to check the edge-sealing situation, avoiding the situation where it is difficult to turn over a long single-piece carpet halfway when it is being pressed tightly.

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.

[0024] Please refer to Figures 1-5, the present utility model provides a technical solution: a pressing structure of an automatic edge locking machine, including a blanket supporting table 1. A plurality of lifting rollers 101 are rotatably connected to the top surface of the blanket supporting table 1. A blanket body 102 is lapped on the lifting rollers 101. An edge locking device 103 is installed on one side of the blanket supporting table 1; the edge locking device 103 is an existing technology.

[0025] Pressing blanket assemblies 2 are provided on both sides of the edge locking device 103 and are located above the blanket supporting table 1. The pressing blanket assembly 2 includes mechanical bin shells 201 symmetrically fixed to the outside of the blanket supporting table 1. A motor bin is fixedly installed at the bottom of the mechanical bin shell 201. A driving motor 202 is fixedly connected inside the motor bin. The output end of the driving motor 202 extends into the mechanical bin shell 201 and is fixedly connected to a threaded rod 203. The top end of the threaded rod 203 is rotatably connected to the mechanical bin shell 201.

[0026] A threaded sleeve 204 is threadedly slidably connected to the outside of the threaded rod 203. A lifting rod 205 is fixedly connected to the outside of the threaded sleeve 204.

[0027] The top end of the lifting rod 205 slidably penetrates through the mechanical bin shell 201 and is fixedly connected to a fixing frame 206. A flipping assembly 3 is arranged above the fixing frame 206; the flipping assembly 3 includes an adjusting bin 301 fixed to the outside of one fixing frame 206. A first motor 302 is installed inside the adjusting bin 301. The output end of the first motor 302 is fixedly connected to a connecting plate 303; the fixing frame 206 is a recessed-shaped frame body. The connecting plate 303 and the rotating plate 313 are both inside the recess. The two first motors 302 are set with different speeds, and the first motor 302 in the carpet entering direction is slower.

[0028] The connecting plate 303 is snap-fitted with a rotating roller shaft 304. The other end of the rotating roller shaft 304 is rotatably connected to a rotating plate 313. The rotating plate 313 is rotatably connected to the fixing frame 206 on the other side. The two sides of the rotating plate 313 are rotatably connected to the fixing frame 206, so that the rotating roller shaft 304 can rotate upward. A tube body is fixed to the outside of the rotating roller shaft 304, and the tube body is in contact with the carpet.

[0029] A through hole 305 is formed in the rotating roller shaft 304. The connecting plate 303 and the through hole 305 are penetrated by an insertion rod 306. One end of the insertion rod 306 is fixedly connected to a docking head 307. A fixing cap 308 is installed on the outside of the docking head 307. Two engaging columns 309 are symmetrically slidably connected to both sides of the fixing cap 308; a recessed groove is formed in the docking head 307, and the recessed groove is engaged with a engaging block 310.

[0030] One end of the engaging post 309 is fixedly connected with an engaging block 310, the other end of the engaging post 309 is fixedly connected with a pull ring 311, the side of the pull ring 311 is fixedly connected with a first spring 312, the first spring 312 is sleeved outside the engaging post 309, and the engaging block 310 is engaged with the docking head 307; the first spring 312 is fixedly connected with the outside of the fixing cap 308, and can pull the engaging post 309 to push the engaging block 310 to engage with the docking head 307, so that the insertion rod 306 cannot be separated at will, increasing the installation stability of the rotating roller 304 and the connecting plate 303.

[0031] Working principle: Before using the pressing structure of the automatic edge-locking machine, it is necessary to first check the overall situation of the device to ensure that it can work normally. According to Figure 1 - Figure 5 As shown in the figure, when initially delivering the carpet, first send the carpet under a rotating roller 304, and then start the driving motor 202 to make the threaded rod 203 drive the threaded sleeve 204 to move vertically, so that the lifting rod 205 drives the height change of the fixing frame 206, and finally makes the rotating roller 304 press the carpet tightly on the lifting roller 101. Then start the first motor 302 to make the rotating roller 304 send the carpet into the edge-locking device 103 stably and uniformly. When the carpet passes through another rotating roller 304, by making the rotation speed of the other driving motor 202 slightly faster, there is a speed difference in the set rotation speeds of the two rotating rollers 304. The actual situation is that one rotating roller 304 will pull the carpet straight due to the faster rotation speed, and because the other end of the carpet is pressed by the rotating roller 304, the carpet will not move due to the faster pulling. Finally, it directly ensures that the subsequent carpet always remains straight during processing, avoiding manually pulling or pressing the carpet at the beginning;

[0032] Moreover, when specially processing a single large carpet, when the edge-locking reaches a certain distance of the carpet, by pulling the pull ring 311, the engaging block 310 is disengaged from the docking head 307, so that the fixing cap 308 can be disassembled, and then the insertion rod 306 can be disassembled. Then one end of the rotating roller 304 can be turned upwards, and then the carpet can be directly turned over, so that the other side of the carpet can be edge-locked. And after replacing the device or the color of the edge-locking thread, repeat the operation, so that the thread colors during carpet edge-locking can be distributed in a staggered manner, increasing the beauty of the carpet, and it is also convenient to directly turn over the carpet in the middle of edge-locking to check the edge-sealing situation, avoiding the situation that it is not easy to turn over a long single-piece carpet when it is pressed.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
