Description

Technical Field

[0001] The utility model relates to a cloth discharging mechanism, in particular to a cloth discharging mechanism with cooling function and cloth manipulation function, belonging to the technical field of textile and light industry. Background Art

[0002] Open width knitted blanket steaming preshrinking machines are developed and manufactured by many European equipment manufacturers.

[0003] These enterprises have accumulated a lot of experience in equipment development and manufacturing over a long period of time. However, as an important component of the steam preshrinking machine for open-width knitted blankets, the preshrinking machine has many styles and structures in the domestic market, and its use effect is also mixed. In summary, there are mainly the following structures and disadvantages:

[0004] Existing plan 1:

[0005] 1. The cloth discharging frame consists of: cloth discharging conveying mechanism + cloth manipulation mechanism + air suction mechanism;

[0006] Fabric conveying structure: transmission roller + tensioning roller + polyurethane mesh belt conveyor;

[0007] The swing frame consists of aluminum rollers + swing arms on both sides + counterweight rods;

[0008] The air suction mechanism consists of: fan + air suction channel;

[0009] The anti-static device consists of: anti-static rod + control power supply;

[0010] 2. Working principle: The pre-shrunk fabric is transported to the cloth output rack by the traction roller, and is further transported forward by the cloth output conveying mechanism. When the fabric passes through the suction channel, the suction mechanism sucks the air above the fabric through the centrifugal fan to form a negative pressure, thereby achieving rapid cooling of the fabric. The swing mechanism continues to pull the fabric that has been transported out from the front down with the aluminum roller, and swings back and forth at a fixed angle to achieve the stacking of the fabric in the turnover vehicle.

[0011] 2.1 Driving mode of the cloth swing frame: motor drives the disc + single connecting rod drives the cloth swing frame;

[0012] 2.2 Fabric delivery drive mode: independent motor drives the transmission roller and circulates the conveyor through PTFE mesh belt + tension roller;

[0013] 2.3 Driving mode of suction mechanism: An independent motor drives the fan to form negative pressure above the channel, quickly cooling the fabric running above, and at the same time this part of the air is extracted to the outside through the pipe.

[0014] 2.4 Installation method of cloth delivery rack: The cloth delivery rack is installed to the pre-shrinking rack through a heightened tripod transition, and the whole is in a parallel state;

[0015] 3. Disadvantages:

[0016] The cloth rack drive does not run smoothly, the driving connecting rod is stuck and easily damaged because there is a dead point in the disc and the force is uneven; it is difficult to repair and replace parts because of the unreasonable structure and small space.

[0017] The energy consumption and cost are high because an independent motor is required to drive the cloth frame.

[0018] The structure is complicated and the installation is inconvenient, because the cloth swing frame is composed of aluminum rollers + swing arms on both sides + counterweight rods, and pulleys are required between the aluminum rollers to drive them again.

[0019] The appearance is affected and the overall strength is reduced. This is mainly because the height of the pre-shrinking rack is limited. When installing the cloth delivery rack, it must be installed to the pre-shrinking rack through a heightened tripod.

[0020] Existing solution 2:

[0021] 1. The cloth discharging frame consists of: cloth discharging conveying mechanism + cloth manipulation mechanism + air suction mechanism;

[0022] Fabric delivery structure: transmission roller + tensioning roller + conveyor belt;

[0023] The swing frame is composed of wooden board + swing arms on both sides;

[0024] The air suction mechanism consists of: fan + air suction channel;

[0025] The anti-static device consists of: anti-static rod + control power supply;

[0026] 2. Working principle: The pre-shrunk fabric is transported to the cloth output rack by the traction roller and is further transported forward by the cloth output conveying mechanism. When the fabric passes through the suction channel, the suction mechanism sucks the air above the fabric through the centrifugal fan to form a negative pressure, thereby achieving rapid cooling of the fabric. The swing mechanism makes the fabric delivered from the front fall straight down and swings back and forth at a fixed angle to achieve the stacking of the fabric in the turnover vehicle.

[0027] 2.1 Driving mode of the cloth swing frame: the transmission roller drives the disc + double connecting rod to drive the cloth swing frame;

[0028] 2.2 Fabric delivery drive mode: independent motor drives the transmission roller and circulates the conveyor through PTFE mesh belt + tension roller;

[0029] 2.3 Driving mode of suction mechanism: An independent motor drives the fan to form negative pressure above the channel, quickly cooling the fabric running above, and at the same time this part of the air is extracted to the outside through the pipe;

[0030] 2.4 Installation method of cloth delivery rack: the cloth delivery rack is directly fixed to the pre-shrinking rack;

[0031] 3. Disadvantages:

[0032] The cloth frame drive is not smooth, the driving connecting rod is stuck and easily damaged. The reason is that there is a dead point on the disc. When maintenance is needed, it is difficult to repair because of the small space and unreasonable layout.

[0033] The process is complicated and the processing cost is high. The wooden board is easy to bend and deform. The reason is that the cloth rack is composed of wooden board + swing arms on both sides. The wooden board needs to be fixed on the swing arm with screws. The surface of the wooden board needs to be very smooth and the wooden board is easy to bend and deform under stress after long-term use.

[0034] The installation method of the cloth delivery rack is unreasonable, and the space reserved underneath is too small: the main reason is that the cloth delivery rack is directly fixed to the pre-shrinking rack, but the overall shape is bulky and occupies a large space, affecting the operation of the pre-shrinking rack by the workers below.

[0035] In general, the current structure is complex, the shape is not beautiful, the cost is high, it is easy to damage and difficult to maintain. In particular, the structure and drive mode of the cloth rack are the primary problems. Summary of the invention
