Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to a multi-station reciprocating suction printing base. Background Art

[0002] A heat transfer printing machine is a device used in heat transfer printing technology. It uses heat and pressure to transfer images, texts or patterns from a film (a special plastic film) to a printing substrate, such as mobile phone cases, clothes, ceramics, etc. The working principle of the heat transfer printing machine is mainly based on heat transfer technology. In the transfer process, first, the designed image or pattern is printed on the film, and then through the high temperature and high pressure action of the heat transfer printing machine, the ink or pigment layer on the film is tightly combined with the surface of the printing substrate, thus realizing the transfer of the image. In this process, the heat transfer printing machine precisely controls parameters such as temperature, pressure and time to ensure the clarity and stability of the transfer effect. Currently, such heat transfer printing machines usually have a flip-top structure. After completing the printing of a batch of printing substrates, the lid is opened to take out the printing substrates, and then the printing substrates are re-placed for heat transfer printing. The degree of automation and efficiency are relatively low, which is not conducive to large-scale printing. At the same time, there is a phenomenon that the film is displaced due to negative pressure during the transfer process, resulting in deviation in the positions of the film of each printing substrate during transfer, affecting the heat transfer printing effect, and there is room for improvement.

Specific Embodiment

[0024] Embodiment 1, referring to the attached drawings of the specification Figures 1-3 , a multi-station reciprocating suction printing base, comprising a base body and a suction printing table assembly installed in the base body. The side and bottom of the base body are both covered with a heat preservation shell, and the overall heat preservation shell is used to isolate the heat transfer between the base and the outside world, reduce the heat loss speed, and is beneficial to reducing energy consumption. Two slide rails are symmetrically arranged between the two ends of the skeleton of the base body. Both sides of the bottom surface of the suction printing table assembly are provided with sliders. A rack is arranged between the two sliders along the width direction of the suction table assembly. The two sliders are slidably sleeved on the two slide rails in a matching manner. The suction printing table assembly can slide along the two slide rails through the sliders. A motor is vertically and fixedly installed in the middle of the skeleton. A gear meshing with the upper rack is installed on the output shaft of the motor. The motor drives the gear to rotate, and the gear drives the suction printing table assembly to reciprocate along the slide rail through the rack.

[0025] A travel switch is provided on the frame in the middle of the seat body, and a trigger baffle corresponding to the travel switch is provided at the bottom of the outer side of the blotting table assembly. The baffle is used to trigger the forming switch, and the motor is controlled by the travel switch, thereby controlling the blotting table assembly to stop moving after reaching the thermal transfer station.

[0026] Example 2, see the attached specification Figures 4-7 On the basis of the first embodiment, the embodiment designs the printing table assembly to include a vacuum seat and a vacuum plate. The vacuum plate is matched and installed in the receiving groove inside the vacuum seat. The receiving groove is used to place the printing material. A plurality of transverse wide grooves are evenly arranged in the middle of the bottom surface of the vacuum plate. A longitudinal wide groove is arranged in the middle of the transverse wide groove. A negative pressure channel is formed between the transverse wide groove, the longitudinal wide groove and the groove bottom of the receiving groove. A plurality of suction holes are densely distributed in the transverse wide groove and the longitudinal wide groove. A connecting hole corresponding to the intersection of the transverse wide groove and the longitudinal wide groove is arranged in the middle of the vacuum seat. The connecting hole is connected to the negative pressure channel. A vacuum joint is installed in the connecting hole. The vacuum joint is connected to a vacuum pump. Vacuum is drawn into each negative pressure channel through the vacuum pump. A plurality of support blocks are evenly arranged on the upper surface of the vacuum plate through screws. A positioning hole docking with the suction hole is arranged in the middle of the support block. The printing material is placed on the support block. The support block is used to support the printing material to avoid deformation caused by negative pressure. At the same time, the suction force generated by the positioning hole can adsorb and fix the printing material to keep it in a stable state.

[0027] An electric heating plate is fixedly mounted on the bottom surface of the vacuum seat. The size of the electric heating plate is larger than that of the vacuum seat. The vacuum seat is heated by the electric heating plate.

[0028] A square frame groove body is provided at the edge of the bottom surface of the vacuum plate. The square frame groove body is connected to the horizontal wide groove body through a connecting groove A, and the square frame groove body is connected to the longitudinal wide groove body through a connecting groove B. Suction holes are provided in the square frame groove body, connecting groove A and connecting groove B. The wide groove bodies are concentrated in the support block area to make the negative pressure relatively concentrated in the area where the printing substrate is placed, thereby generating a greater adsorption force on the film in this area and improving the printing effect. Narrower groove bodies such as the square frame groove body and the connecting groove are distributed at the edge to generate adsorption force on the film at the edge and control the overall stability of the film.

[0029] The blotting table assembly is installed in a hollow heat-insulating shell and connected to the slide rail through the heat-insulating shell. The heat-insulating shell provides heat preservation for the blotting table assembly and forms a two-stage heat-insulating structure in combination with the heat-insulating shell on the seat.

[0030] When the printing table assembly works, open the edge pressing cover upward, place each printing object on each supporting block in sequence, cover the film on the upper port of the vacuum seat, and then cover the edge pressing cover downward. Each suction cup sucks and fixes the edge pressing cover tightly. At this time, the sealing strip between the edge pressing cover and the vacuum seat presses the edge part of the film tightly. Each pattern on the film corresponds to each printing object respectively. Then start the negative pressure pump to pump vacuum into the vacuum channel from the vacuum joint. Negative pressure is generated on the surface of the vacuum plate, and the film is sucked tightly on the surface of the printing object. Then turn on the electric heating plate to perform heat transfer printing.

[0031] Embodiment 3, see the attached Figures 4-5 In this embodiment, on the basis of Embodiment 2, an edge pressing cover is provided in the printing table assembly. The edge pressing cover is hinged to the vacuum seat through a hinge and can be turned up and down. An upper sealing strip is provided on the bottom surface of the edge pressing cover, and a lower sealing strip is correspondingly provided on the upper surface of the vacuum seat. A number of suction cups are evenly provided on the edge part of the electric heating plate, and the suction cups correspond to the bottom surface of the edge part of the edge pressing cover. When the edge pressing cover is used, it is turned up, and then the film is horizontally placed on the upper port of the vacuum seat, and then the edge pressing cover is pressed downward. The edge part of the film is pressed tightly between the upper sealing strip and the lower sealing strip. At this time, the evenly arranged suction cups adsorb on the bottom surface of the edge pressing cover, so that the film is in a fixed state in the vacuum seat, and the film will not have a large displacement due to negative pressure during the vacuum pumping and transfer process, ensuring that the printing objects at multiple stations can be vertically aligned with each pattern of the film, and ensuring the heat transfer printing effect.
