The following detailed description of implementations of the present application is provided in conjunction with specific embodiments.

As shown in fig. 1 to 3, the present embodiment provides a baking machine, which includes a baking oven 1, a heating pipe 2 disposed in the baking oven 1, a plurality of baking brackets 3 slidably mounted on the baking oven 1, and a sliding driving mechanism 4 for driving the baking brackets 3 to slide relative to the baking oven 1. Slide actuating mechanism 4 can drive toast bracket 3 business turn over oven 1, also places slide actuating mechanism 4 and can drive toast bracket 3 and get into oven 1 after waiting to toast the product on toasting bracket 3 promptly, and after the product was toasted, slide actuating mechanism 4 can drive toast bracket 3 and slide and realize the outside that most positions arrived oven 1 relatively oven 1, and the operator personnel can take out the product of accomplishing the toasting. The plurality of toasting carriages 3 are arranged in sequence in the height direction of the toaster 1, i.e. the plurality of toasting carriages 3 are arranged in a stacked manner, but adjacent toasting carriages 3 are not in contact with each other. The sliding driving mechanism 4 can drive each baking bracket 3 independently, and the single baking bracket 3 can be moved in and out independently.

In the embodiment of the present application, a plurality of toasting carriages 3 are arranged along the height of the toaster 1 (i.e. the vertical direction of the toaster 1 when the toaster is normally placed in use), and each toasting carriage 3 can be placed with a certain amount of product to be toasted, the product in one toaster being the sum of the amounts of product on the respective toasting carriages 3. Compared with the prior tunnel type, the horizontal conveying flat baking equipment adopting the conveying belt can fully utilize the space of the baking machine in the height direction and effectively reduce the occupied area of the baking machine under the condition of baking the same number of products.

Meanwhile, the sliding driving mechanism 4 can drive the baking bracket 3 to enter and exit the baking oven 1, so that the baking machine can be operated by one person to finish the operations of putting the product into the baking bracket 3 and taking the product off from the baking bracket 3. And current tiled toast equipment, because area is great, all set up operating personnel at the both ends of toasting equipment, the staff of one end puts into the conveyer belt of toasting equipment with the product, and other end personnel take out the product from the conveyer belt of toasting equipment, need two people at least to operate, need operate more than 4 people to great equipment.

Optionally, the heating pipes 2 may be multiple, and the heating pipes 2 may be disposed above each baking bracket 3, so that the heat received by the product on each baking bracket 3 is approximately the same, and the consistency of the baked product is improved.

Referring to fig. 1-2, as another embodiment of the baking machine provided by the present application, the baking oven 1 is provided with a plurality of openings 101 adapted to the baking brackets 3, and each baking bracket 3 is inserted into the opening 101. That is to say, each opening 101 corresponds to a baking bracket 3, and baking bracket 3 inserts in oven 1 from opening 101, can effectually seal opening 101, and the inside heat of oven 1 is difficult for outside diffusion, promotes the utilization ratio of the energy, reduces the power consumption of product. Because the heat is not easy to expose, the temperature in the oven 1 is easy to maintain, the power of the heating pipe 2 can be reduced, and the stability of the temperature in the oven 1 can be maintained only by continuously supplementing smaller heat.

Referring to fig. 3-4, as another embodiment of the roaster of the present application, the roasting bracket 3 includes a supporting base 301 slidably mounted on the roaster 1, and a cover plate 302 connected to the supporting base 301 and located outside the roaster 1; the cover plate 302 is connected to the slide drive mechanism 4.

The sliding driving mechanism 4 is connected to the cover plate 302, so as to drive the baking bracket 3 to slide integrally. Since the sliding driving mechanism 4 is connected to the cover plate 302, the sliding driving mechanism 4 can be disposed outside the oven 1, the temperature outside the oven 1 is lower than the temperature inside the oven 1, the high temperature resistance of the sliding driving mechanism 4 is not high, the product of the sliding driving mechanism 4 is not easy to be damaged by high temperature, and the replacement and maintenance of the sliding driving mechanism 4 are facilitated.

Since the cover plate 302 needs to be connected to the sliding driving mechanism 4, the cover plate 302 has a relatively high hardness, and is not easily deformed to enable the baking tray 3 to be driven by the sliding driving mechanism 4 to stably slide, so that after the cover plate 302 closes the opening 101, a gap may exist between the cover plate 302 and the opening 101, and heat is easily leaked from the gap. Set up the closing plate 303 on the surface that apron 302 and oven 1 just right, this closing plate 303 can be softer plate, and the closing plate 303 can take place micro-deformation after with oven 1 surface contact, and then with the better laminating in oven 1's surface, realize the better closure of opening 101 to effectual promotion is to the closure of opening 101, makes the heat be difficult for outwards leaking.

Since the heat is not easily leaked out, the temperature inside the oven 1 is easily kept stable, that is, is not easily different from the preset value at or near the preset value. The baked products are stable in temperature, after the baking is carried out for a fixed time, the quality of the products is high, defective products are not prone to occurring, the consistency of products in the same batch is high, and the quality of the products can be guaranteed especially for electronic products with high precision requirements.
