The invention relates to the field of article stacking and orderly placing devices and the construction field of frame type structural bodies, and aims to provide a multipurpose stacking, supporting and orderly placing device and a multipurpose stacking, supporting and orderly placing combined device of the multipurpose stacking, supporting and orderly placing device. The stacking, supporting andorderly placing device comprises a corner-shaped wall structure which is formed by connecting two support walls into a whole. A vertical matching connection structure and a lateral matching connectionstructure are arranged on the corner-shaped wall structure, so that the stacking frame code device can be sequentially overlapped and connected in the vertical direction with a matching connection structure of a supported and orderly placed object through the vertical matching connection structure or can be laterally connected with a matching connection structure of a beam type component throughthe lateral connection structure, or a plurality of stacking, supporting and orderly placing devices are sequentially stacked in the vertical direction through the vertical matching connection structure so as to adjust the supporting height and / or are connected in an abutting mode through the lateral matching connection structure to increase the number or thickness of supporting walls. The multipurpose stacking, supporting and orderly placing device and the multipurpose stacking, supporting and orderly placing combined device of the multipurpose stacking, supporting and orderly placing devicehave the beneficial effects that the layered stacking of various supported and orderly placed objects and the quick construction of various frame type structural bodies are facilitated.

The invention relates to an automatic feeding device for a spacer. The automatic feeding device comprises a charging basket base, an ejector pin and an ejector pin moving module, and further comprises a separation plate and a charging basket. A separation plate outlet is formed in the separation plate. A spacer storage hole is formed in the charging basket in the axial direction. The spacer is stored in the spacer storage hole. The center lines of a charging basket base through hole, the separation plate outlet and the spacer storage hole coincide with one another. The ejector pin penetrates through the charging basket base through hole to be inserted in the spacer storage hole of the charging basket, and the upper end of the ejector pin is propped against the spacer. Through the technical scheme, manual placing can be replaced, and the defect of a conventional feeding process is eliminated; thousands of spacers can be stored at one time, automatic feeding can be realized, misoperation that two or more spacers are sucked synchronously can be effectively prevented, a spacer tray and a process of placing the spacers manually are omitted, the using cost of a tool jig is reduced, personnel allocation requirements are reduced greatly, the production efficiency is improved effectively, and the production and manufacturing cost is reduced.

The invention relates to a ceramic heating piece for a laser printer and a manufacturing process thereof, wherein a ceramic substrate is sintered with a film heating wire, two ends of the film heating wire are provided with extraction electrodes, a medium covering layer is arranged outside the film heating wire, the ceramic substrate is made from aluminum oxide, and the covering layer is made from glass glaze. The manufacturing process comprises the following steps: printing a conductive sizing agent on the substrate, performing high temperature sintering for the first time, printing a noble metal sizing agent, performing the high temperature sintering for the second time, printing a glass glaze sizing agent, and performing the high temperature sintering for the third time. The ceramic heating piece has the advantages of having low price, providing a convenient and practical objective condition for the regeneration of a damaged laser printer, and being advantageous for the developmentand the popularization of environmental protection and regeneration.

The invention discloses a forming method and forming equipment of a strip-penetrating-method inner cavity polyurethane foaming metal section, which are used for producing the strip-penetrating-method inner cavity polyurethane foaming metal section. The forming method comprises the following steps: firstly, a section A and a section b that are provided with dovetail grooves are manufactured respectively, and a penetrating strip A and a penetrating strip B are manufactured through extrusion and penetrate into the dovetail groove of the section A for forming a U-shaped cavity; a clamping block A and a clamping block B, or self-adhesive films, or self-adhesive sheets are used to seal U-shaped notches in the two ends of the U-shaped cavity, an adhesive supply device is used to inject polyurethane to the U-shaped cavity, and after a polyurethane A adhesive and a polyurethane B adhesive are mixed in an adhesive injection head, a mixture flows out of an adhesive injection mouth and flows into the U-shaped cavity; after standing for 2-20 minutes, polyurethane foaming strips are formed, space of the U-shaped cavity is filled with the polyurethane foaming strips, and the functions of bonding and strength improvement are exerted. One-time combination forming and polyurethane foaming strip on-line casting are realized, the strip-penetrating-method inner cavity polyurethane foaming metal section is formed quickly, the forming method is simple and quick, strip penetrating equipment and technological links are saved, and the production efficiency is improved.
