Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, and particularly relates to a calender conveyor for artificial leather production. Background Art

[0002] During the production of artificial leather, raw materials are mixed in a mill before being filtered in a filter press. The filtered raw materials then enter a calender. Conveyors are used to transport the raw materials between the mill, filter press, and calender. During operation, the calender can push impurities from the center of the drum toward the ends, where they accumulate at the edges of the sheet. A cutter then removes the impurities by cutting the edges. However, since the cut edges contain raw materials, discarding them directly would result in a waste of raw materials and fail to meet production needs. Therefore, a calender conveyor for artificial leather production is needed to address these technical issues. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the utility model provides a calender conveyor for artificial leather production, comprising a calender, a filter press and an open mill, wherein a conveyor 1 is provided between the discharge port of the open mill and the inlet of the filter press, and a conveyor 2 is provided between the discharge port of the filter press and the inlet of the calender; a waste conveyor is provided on the calender, and the discharge end of the waste conveyor is matched with a conveyor 3, the discharge end of the conveyor 3 is matched with a conveyor 4, the discharge end of the conveyor 4 is matched with a conveyor 5, and the discharge end of the conveyor 5 is matched with the feed port of the open mill;

[0004] The conveyor three is arranged in parallel with the conveyor two, and the conveyor three is fixed above the conveyor two. The conveying direction of the conveyor three is opposite to that of the conveyor two. The conveyor five is arranged in parallel with the conveyor one, and the conveyor five is fixed above the conveyor one. The conveying direction of the conveyor five is opposite to that of the conveyor one.

[0005] The present invention adds a waste conveyor, conveyor three, conveyor four and conveyor five on the basis of not changing the original raw material transfer conveyor between the open mill, filter press and calender. The cut edge of the film can be transported to conveyor three through the waste conveyor, and then pass through conveyor four and conveyor five in sequence to enter the open mill to be mixed with other raw materials, heated, and filtered again through the filter press. After the impurities are filtered, it enters the calender, realizing the separation of raw materials and impurities in the waste, realizing the reuse of raw materials, and reducing the waste of raw materials. In the above process, the newly added conveyor three is located above conveyor two, and conveyor five is located above conveyor one. The raw materials transported by conveyor one and conveyor two contain more heat. The heat emitted by the raw materials can keep the waste on conveyor three and conveyor five warm, preventing the waste from cooling and hardening, reducing heat waste, improving energy utilization, and further reducing the time the waste is mixed in the open mill.

[0006] Preferably, the second conveyor is connected to a pushing assembly, which includes a push rod, a horizontal connecting rod, a rotating motor, and a vertical bracket. A connecting plate is fixed to the top of the bracket, one end of the connecting plate extends to the feed end of the second conveyor and is hinged to the frame of the feed end of the second conveyor. The rotating motor is arranged at the top of the bracket, and the output shaft of the rotating motor is vertically upward and fixedly connected to one end of the connecting rod. The connecting rod is hinged to one end of the push rod, and the other end of the push rod is hinged to the middle of the frame of the second conveyor. The calender is provided with a horizontal support rod. The discharge end of the second conveyor passes above the support rod and extends to the feed port of the calender. The support rod contacts the frame at the bottom of the second conveyor. The rotation of the rotating motor drives the connecting rod to rotate, and the push rod connected to the connecting rod drives the second conveyor to reciprocate periodically, so that the second conveyor can swing back and forth with its feed end as the center, thereby increasing the distribution range of the discharge end of the second conveyor on the calender, improving the uniformity of the calender feed, and improving efficiency and quality.

[0007] Preferably, the waste conveyor includes a sixth conveyor and a seventh conveyor. A gantry is provided above the frame of the sixth conveyor. The top of the gantry is connected to the lower surface of the support rod via a universal joint. Guide chutes are provided on both side walls of the frame of the sixth conveyor. The discharge end of the seventh conveyor cooperates with the third conveyor. The feed end of the seventh conveyor is located below the sixth conveyor. Slide blocks are fixedly connected to the two sides of the frame of the feed end of the seventh conveyor via connecting blocks. The two slide blocks are slidably arranged in corresponding guide chutes. This arrangement allows the total length and tilt direction of the waste conveyor to be flexibly changed when the feed end of the third conveyor continuously swings with the discharge end of the second conveyor, ensuring that the discharge end of the seventh conveyor cooperates with the feed end of the third conveyor, so that waste can be smoothly transferred from the seventh conveyor to the third conveyor.

[0008] Preferably, the feed end of Conveyor 3 is equipped with an infeed conveyor. The frame of the infeed conveyor is fixedly connected to the frame of Conveyor 3, and the frame of the infeed conveyor is fixedly connected to the frame of the discharge end of Conveyor 7 via a fixed block. The provision of the infeed conveyor reduces the bending degree of waste material from Conveyor 7 to Conveyor 3, making the transition smoother and preventing waste material from breaking and affecting the conveying effect.
