A two-axis modular belt comprising two orthogonal belt loops intersecting at a union on a carryway. The belt is constructed of rectangular belt modules arranged in rows and columns. The modules are interconnected by hinge elements that allow columns of an advancing belt loop to translate relative to the rows of the other stationary belt loop.

A modular conveyor belt module includes a base body extending along a first direction transverse with respect to the transport direction, between two opposite lateral faces. The module includes upper and lower surfaces; two opposed longitudinal edges; hinge elements projecting respectively from the two edges along a second direction. Each of the first and second hinge elements is crossed by a first and second hole, respectively, the axes of the holes being parallel to the first direction. The holes are each coaxial to each other. The first hinge elements interpose the second hinge elements of another module with the respective holes coaxially aligned. The hinge elements are interposed to each other leaving free spaces to receive a roller. Each roller projects with a portion from the upper surface, the plane parallel with respect to the two directions and tangent to the portion of the rollers projecting from the upper surface.

A modular conveying assembly that includes a plurality of roller bodies, a driving member, a positive stop body, and a positive stop actuator. Each roller body includes a top surface, a driven axle mounted to the roller body for conveyance therewith, a roller fixed to the driven axle, and a driven surface fixed to the driven axle. The rollers define a support plane. The driving member selectively engages the driven surfaces to affect rotation of the driven axle. The positive stop body is coupled to the plurality of roller bodies and includes a positive stop that is movable relative to the positive stop body between a first position and a second position. The positive stop extends above the support plane in the second position. The positive stop actuator selectively engages the positive stop to move the positive stop between the first position and the second position.

A freezing spiral net chain structure includes a plurality of chain links successively arranged in a travelling direction of a rail. Transmission teeth are arranged at inner ends of the chain links. Engagement teeth are arranged at two sides of the chain links. The engagement teeth of the adjacent chain links are engaged with each other. Axial holes are disposed between the mutually engaged engagement teeth. Rotary shafts are inserted into the axial holes. A metal piece is connected between outer ends of every two adjacent rotary shafts. The metal piece may bear a load from an outer-end spiral net, and since a coefficient of expansion of metal is smaller than that of plastic, deformation between the adjacent rotary shafts as a result of cold shrinking is reduced. The metal piece is different from the rotary shafts of the plastic spiral conveying net chain in terms of pitch.
