Background

Patent document CN104260543A discloses a cutting piece positioning device for a printing machine and the printing machine. The cut-parts positioner is arranged on the guide belt, and in the cut-parts printing and dyeing process of the printing machine, initially, the limiting seat is positioned above the guide belt, the bedplate attached with the cut-parts is abutted against the limiting seat, and the bottom of the front end of the bedplate is in contact with the guide belt which has the trend of driving the bedplate to convey forwards. Then, the limiting seat is lifted, and the bedplate is driven by the guide belt to move forward along the guide belt. Thus, there are the following technical problems: firstly, the thickness of the bedplate can be thin, the bottom of the front end of the bedplate is contacted with the conduction band, the limiting seat blocks the front end of the bedplate to prevent the bedplate from advancing along the conduction band, so that the vertical distance between the limiting seat and the conduction band is small, even the limiting seat can be contacted with the conduction band to cause the limiting seat to rub the conduction band; second, a plurality of guide rails constitute a plurality of guide gaps, and a platen is placed to each guide gap, and cut-parts positioner can hold a plurality of platens, but, for spacing seat lifting once, a plurality of platens can move ahead in step, so, the platen of placing earlier is in the frictional state with the conduction band always, and the platen is all placed to all guide gaps, spacing seat lifting. The friction, whether between the limit seat and the guide belt or between the guide belt and the platen (in a stationary state), is disadvantageous for the limit seat, the guide belt and the platen.

Detailed Description

With reference to fig. 1 and 2, a cut-parts positioning device of a decorating machine comprises a frame and a guide rail 10 mounted on the frame, wherein a rotating shaft 20 is arranged on the frame, a bracket 21 and a baffle 22 are arranged on the rotating shaft, and the rotating shaft is connected with a driving mechanism 30; the guide and belt 90 have a fore-aft gap and the carriage and the stop are located in the gap between the guide and the guide.

Under the drive of the driving mechanism, the rotating shaft has two working positions, when the rotating shaft is positioned at the first working position, the baffle can block the bedplate 80 which moves forwards along the guide rail, and the bracket is positioned below the bedplate; when the rotating shaft is in the second working position, the baffle is positioned below the bedplate, and the bedplate is lifted by the bracket and is conveyed forwards to the guide belt.

Initially, as shown in fig. 3, the rotating shaft 20 is in the first working position, and the operator pushes the table 80 with the cut pieces attached thereon, so that the table advances along the guide rail. If the number of rails is several pairs, a pallet is carried between each pair of rails, and the operator places the pallets successively between the pairs of rails and pushes the pallets 80 forward so that each pallet abuts the apron 22 and the pallets are in place. The operator then actuates the drive mechanism 30 which rotates the shaft 20, as shown in fig. 4, so that the flap 22 rotates downwards and no longer blocks the platen, and the carriage 21 rotates upwards to lift and advance the platen onto the belt 90, at which time the shaft is in the second operating position, as shown in fig. 5. If the number of guide rails is several pairs, the shutter 22 releases all the platens simultaneously and the carriage 21 delivers all the platens simultaneously onto the guide belt 90.

Alternatively, as shown in fig. 2, the number of rails 10 is two pairs, each pair carrying a platen 80; two large-diameter sections 201 are arranged on the rotating shaft 20, the two large-diameter sections respectively correspond to the two pairs of guide rails, and a bracket 21 and a baffle 22 are arranged on each large-diameter section. The two baffles and the two brackets rotate synchronously along with the rotating shaft.

The carriage 21 is provided with a cylindrical roller 210 which can contact the bottom surface of the platen 80. The cylindrical rollers contact the bottom surface of the platen during the carriage lifting and transporting the platen forward. The cylindrical roller is fixedly connected with the bracket main body, and a rubber layer can be arranged on the cylindrical roller to increase the friction force with the bottom surface of the bedplate and avoid slipping in the process of conveying the bedplate.

Referring to fig. 1 and 2, the driving mechanism 30 includes a first swing link 31 fixedly connected to the rotating shaft 20, a connecting rod 32 movably connected to the first swing link, and a second swing link 33 movably connected to the connecting rod, and the second swing link is hinged to the frame. The upper part of the second swing link is equivalent to a handle, an operator pushes the second swing link forwards, the first swing link swings forwards, the first swing link drives the rotating shaft 20 to rotate forwards, and the rotating shaft is changed from the first working position to the second working position. An operator pulls the second swing rod backwards, the first swing rod swings backwards, the rotating shaft rotates backwards, and the second working position is changed into the first working position. The operation is convenient though the operation is purely manual.

The cross section of the guide rail 10 is L-shaped, the bedplate 80 is placed between the pair of guide rails, the bottom edge of the L-shaped guide rail can support the bedplate, the side edge of the L-shaped guide rail can limit the bedplate, and the L-shaped guide rail can not influence the movement of the bedplate when the bracket 21 is lifted and the bedplate is conveyed forwards.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
