The invention relates to a steel structure profile feeding fixed-length automatic cutting machine. The machine comprises a base, a feeding device, a material distributing device, a cutting device anda discharging device, a feeding cavity and a discharging cavity are formed in the front end of the base from bottom to top, the feeding device and the material distributing device are sequentially installed in the feeding cavity from top to bottom, the cutting device is installed on the upper side of the front end of the base, and the discharging device is installed in the discharging cavity; theadjustable material distributing plate is adopted, so that steel plates with different widths can be fed at the same time; by adjusting the position of the stop block, the steel plate cannot be fed after extending out by a specified length, and the cutting length of the steel plate is controlled; the two ends of the plate are prevented from tilting to influence the cutting precision in a mode of firstly fixing and then cutting; and through discharging of the plates, the conditions that the plates are accumulated on the working platform, efficiency is affected, and the labor intensity of workers is increased are prevented.

The invention discloses a cardboard conveying device for a cardboard stripper for a printing and packaging machine. A stepping motor is arranged in the frame, a rotating shaft is connected to the output shaft of the stepping motor, and a plurality of first sprocket, a pair of first crossbars are arranged above the first sprocket, a plurality of second sprockets are respectively arranged on the pair of first crossbars, a pair of second crossbars are arranged above the first crossbars, the pair of first crossbars A plurality of third sprockets are respectively arranged on the second cross bar, between the first sprocket and the corresponding second sprocket, between the second sprocket and the corresponding third sprocket are connected by connecting rods, and are located at the two most A third crossbar is arranged between the inner third sprockets, and the paper pusher is installed on the third crossbar. The invention also discloses a cardboard conveying method of a cardboard opener for a printing and packaging machine, which is used to realize the transmission and precise positioning of the cardboard, thereby improving production efficiency and reducing waste.

The invention discloses automated high-precision PVC wallboard processing equipment in the field of wallboard processing. The equipment includes a machine body, an L-shaped bracket is fixedly welded to the left side wall of the machine body and includes a vertical member and a horizontal member, and a cutting device is fixed to the left side wall of the vertical member; a horizontal retractable air cylinder is fixed to the upper surface of the horizontal member through bolts, a first motor bracket is arranged at the end of the horizontal air cylinder and fixedly connected with a retractable rod of the horizontal retractable air cylinder, a rotating motor is fixed into the first motor bracket, a vertical connecting board is arranged below the rotating motor, and an output shaft of the rotating motor is fixed to the vertical connecting board. According to the provided automated high-precision PVC wallboard processing equipment, when a cutting motor drives cutting pieces to cut a PVC wallboard, the PVC wallboard can be limited and fixed through limiting blocks, and the situation that the PVC wallboard slants during cutting and the cutting precision is thus influenced is avoided.

The invention relates to the field of manufacturing equipment, in particular to a vertical granulator. The vertical granulator comprises a fly cutter used for conducting cutting. The fly cutter comprises a flat and straight installing part, a cutter body obliquely arranged on the side edge of the installing part, and a blade arranged at the bottom of the cutter body. The lower end face of the cutter body is located below the lower end face of the installing part. The installing part, the cutter body and the blade are integrally formed. The plane where the blade is located is perpendicular to the plane where the cutter body is located. A first included angle is formed by the face, close to the outer side, of the cutter body and the face where the blade is located. A second included angle is formed by the face, close to the inner side, of the cutter body and the face where the blade is located. The first included angle ranges from 8 degrees to 12 degrees, and the second included angle ranges from 25 degrees to 35 degrees. According to the vertical granulator, the fly cutter circumferentially moving is adopted, the fly cutter is perpendicular to the material strip conveying direction, and a product obtained through cutting is attractive in appearance and free of inner arc tip, long in service life and high in cutting precision.

The invention discloses a cloth breaking machine for tie processing. The cloth breaking machine comprises a working table and a cloth breaking device. The cloth breaking device comprises a horizontal locating plate, a cloth breaking mechanism and a control panel. A horizontal sliding groove is formed in the top face of the horizontal locating plate. The cloth breaking mechanism is connected into the horizontal sliding groove in a sliding mode. A steam box is arranged at the left side of the cloth breaking device. A supporting table plate is arranged below the working table. A U-shaped groove is fixedly formed in the supporting table plate. A collecting cylinder is connected into the U-shaped groove in a rotating mode. Two supporting rods perpendicular to the working table are arranged at the right side of the cloth breaking device. A discharging cylinder is arranged between the two supporting rods. A second supporting roller is arranged between the horizontal locating plate and the supporting rods. The cloth breaking machine is simple in structure and high in practicality, cloth can be located conveniently, errors are reduced, the situation that because the cloth of a traditional cloth breaking machine is exposed outside and cut, cloth jumping is caused easily can be effectively avoided, the cloth is prevented from wrinkling when rolling to the upper collecting cylinder, the working efficiency of the cloth breaking machine is improved, cutting precision of the cloth is improved, and use is safe and reliable.
