The invention provides a planar motion structure and belongs to the technical field of planar motion structures. Through the planar motion structure, the problems that certain planar motion structurescan move in the X-axis direction and can also move in the Y-axis direction, and the motion structures are very complex are solved. The planar motion structure comprises a rack provided with a pair offirst screw rods parallelly. The first screw rods are correspondingly provided driving devices driving the first screw rods to rotate. The spiral directions of threads of the first screw rods are opposite. The first screw rods are sleeved with screw rod nut modules. The screw rod nut modules comprise first screw rod nuts and rolling bearings arranged on the first screw rod nuts in a sleeving mode. The rolling bearings are connected through a connecting rod. The first screw rod nuts are connected through a synchronous belt. A synchronous part is provided with a moving block. When rotating in the same direction, the first screw rod nuts drive the moving block to move through the synchronous part. The planar motion structure has the advantages of being simple in structure and the like.

An apparatus (200) for automatically and continuously forming envelopes (51) to contain filter bags (1) for an infusion product comprises: means (60; 129, 131) for forming the envelopes, designed to make on a web (126) of packaging material moving along a predetermined feed path (174) a longitudinal fold line delimiting two adjacent flaps (127) defining an interposed opening through which the web (126) can be laterally accessed by the filter bags (1); manipulating means (123, 148, 128) designed to receive the filter bags (1) in succession, to turn them so that they lie in substantially the same plane as the web flaps (127) and to move the filter bags (1) along a feed path (62a, 62b, 62c) having at least one end stretch (62c) that is substantially centred relative to the web flaps (127), the filter bags (1) moving along the stretch (62c) in the same direction as the paper web (126) before the manipulating means release the filter bags (1) between the web flaps (127).

The invention discloses a lever lateral mobile damping four-wheeler manned lunar rover folding system and belongs to the field of spaceflight. The system solves the problem that a four-wheeler is easily overturned integrally, difficultly climbs, runs into hollow surfaces, works cumbersomely, is high in energy consumption, low in adaptability and occupies a large space to hinder the implementation of exploration tasks and the like under the complicated geographical conditions on the surface of a star in the prior art. One side of a first rover body (1-1) is welded with two right-angled steel channels (6); the other side of the first rover body (1-1) is in folding connection with one side of a second rover body (1-2) through two middle connection folding mechanisms (8); the other side of the second rover body (1-2) is welding with two right-angled steel channels (6); the first rover body (1-1) is detachably connected with the second rover body (1-2) through a pair of rolling shaft pins (9) and pin slots (15); the lower end face of a bearing plate rover (1) is uniformly provided with four dual-wheel moving mechanisms. The system is used for a manned lunar rover.
