Description

Photochrome flushing constant temperature oven

The utility model relates to a kind of photochrome flushing constant temperature oven, and particularly constant temperature mechanism and the printing paper flushing about constant temperature oven holds mechanism.

Being used for photochrome amplifies, the flushing constant temperature oven that uses in the dark place, the early stage constant temperature oven that has Shanghai Suo Weini and Huqiu, Suzhou to produce that uses, it all is with a big plastic box, two plastic plates of weldering in the case, the case internal volume is divided into three lattice, is respectively colour display screen, washing, float and decide groove, the soup consumption is very big, dress heating tube and ebullator in the dipper on both sides, to reach 32.8 ℃ of specific constant temperature of colour display screen technology, middle rinsing bowl, flowing water washing because rinsing bowl and colour display screen, float decide groove only a plate every, colour display screen, float the fluid temperature in fixed two grooves, ceaselessly the cold water of being flowed through in the rinsing bowl by dividing plate is taken away, and well heater and ebullator must heat and circulate continuously, could keep the temperature of spray tank inner liquid medicine, and soup ceaselessly circulates and becomes the liquid level that contacts with air, make oxidation quicken soup and lost efficacy, and this flushing constant temperature oven, adopt and hang printing paper infiltration flushing, once can only wash one to two, efficient is lower, troublesome poeration, and energy consumption is bigger.Because flushing constant temperature oven efficient is lower, the needs of the professional processing of incompatibility, the full-automatic flushing machine that amplifies the color picture flushing appears on the market being exclusively used in, the full-automatic flushing machine adopts roller bearing that printing paper is pinched into colour display screen, it is fixed to float, rinsing bowl, once in blocks through oven dry, this class machinery is bulky, complex structure, and injected volume of soup is bigger, groove uncovered very big, soup contacts with air after heating, and oxidation is accelerated, and need constantly add new soup, and oxide attached to directly with roller bearing that printing paper contacts on, very easily pollute photo, need often to clean normally operation, this full-automatic flushing machine is in pipelining, when washing the photo of same specification amplification continuously, can bring into play its full automatic advantage, at the flushing different size, during intermittent operation, produce the defective of high consumption low yield on the contrary.

At the defective of above-mentioned photochrome flushing constant temperature oven and washer, the purpose of this utility model provides a kind of photochrome that magnifies the photo that differs for a short time that once can wash fast more and washes constant temperature oven, and soup is difficult for oxidation.

The purpose of this utility model is to realize like this, photochrome flushing constant temperature oven, by the constant temperature oven casing, the high rectangle colour display screen case that equates of length and width, float and decide the case composition, fill the water of making heat transfer medium in the casing, colour display screen case and floating is decided case and is immersed in the water in the casing, one temperature probe and electrothermal tube are arranged at the bottom in the constant temperature oven casing, the lead-in wire of electrothermal tube is drawn from box body wall and is inserted thermostat and power supply, the heat-insulation layer of the sidewall and end parcel foamed plastic around the casing, the case top has foamed plastic to make the case lid of insulated building, have on the sidewall of being positioned at respectively on two corresponding sidewalls of casing, advancing of lower end, the water outlet pore, on, connect with pipeline serial connection ebullator between the following Inlet and outlet water pore, the colour display screen case is built-in with the rectangle fence frame that is used to hold printing paper, the opening part of a fence frame side therein, the upper end of open side and corresponding side surface is connected the handle ring that is used to operate, the built-in hard plastic sheet that washes the corresponding size of photograph of fence frame, even shape hole, distribution garden on the hard plastic sheet, bore dia is 20-40mm, the thick 0.1-0.5mm of sheet.

After adopting the photochrome flushing constant temperature oven of this spline structure, electrothermal tube only heats the heat transfer medium water in the constant temperature oven, the heat energy of water through the colour display screen case, float and decide the case tank wall and conduct heat, and make the soup that shows in the photographic fixing case keep constant temperature, soup need not to stir circulation just can reach the very little constant temperature of fluctuation, soup is without stirring, rectangular apparent photographic fixing case inner liquid medicine and air surface of contact are little, so the oxidation of soup can slow down, set fence frame in the colour display screen case, take out before processing, many printing paper that exposure is good, medicine face are placed with the spacer in hole to pad between the medicine face.The printing paper reverse side is to reverse side, stack thickness less than fence frame opening, put into from the lateral opening of fence frame, the fence frame immerses in the soup of colour display screen case, and the handle of fence frame both sides is used for manual operations the fence frame is slightly moved up and down, can make in the fence frame medicine face of printing paper fully contact soup and finish colour display screen, colour display screen finishes, propose the fence frame,, immerse to float to decide to float in the case and decide in clear water part omitted rinsing.So once just can finish the flushing of many printing paper, the water of heat transfer Jie tribute in the constant temperature oven simultaneously, once be heated to temperature required after, external environment is isolated by the outer heat-insulation layer of constant temperature oven, temperature is difficult for scattering and disappearing, and heating tube minimizing heat time heating time can be played energy-conservation effect.

The drawing explanation:

Fig. 1 is the stereographic map of the utility model photochrome flushing constant temperature oven.

Fig. 2 is the stereographic map of fence frame.

Fig. 3 is the planimetric map of spacer.

The utility model is described in further detail in conjunction with the embodiments with reference to the accompanying drawings.

Shown in Figure 1, the heat-insulation layer (2) of around the constant temperature oven casing (1) of plastic production and end parcel foamed plastic, have water-in and water-out pore (3), (4) at upper and lower end respectively on two sidewalls of casing, connect with pipeline (5) serial connection ebullator (6) between the pore, temperature probe (11) is installed in nearly bottom at casing (1) one sidewall, case lid (8) also adds foamed plastic with plastics to be made, the inboard of lid, connect a parting bead on the longitudinal midline, during in order to the push-and-pull case lid, the restriction constant temperature oven is only opened case lid half.The rectangular colour display screen case (12) that stainless sheet steel is made and float and decide in the floating water that is immersed in the constant temperature oven of case (13), electrothermal tube (7) is installed in the nearly bottom of constant temperature oven, and the electrothermal tube power line is drawn access thermostat and power supply from the case side-walls.The fence frame (9) that stainless steel wire is made, framework is made oblong-shaped with the stainless steel wire of 0.8mm, and opening is made in a side, and the stainless steel wire of other each face usefulness≤0.8mm is made fence.Spacer (10) is selected the plastic hard plate of 0.2-0.4mm for use, be evenly distributed with the hole of 40mm on the plastic sheet, the size of plastic sheet and institute's processing size match, quantity is the amount doesn't matter, when only washing 2 following photos, medicine face is supported or opposed, without spacer, when washing two above photos, medicine face is encased inside spacer to the medicine face layer, the quantity of photo flushing adds thickness behind the spacer with printing paper can be put the fence frame into and exceed, and the open side of fence frame and upper end, its corresponding side are connected garden orphan's handle ring (14), manual handle when being used to develop.
