Problems solved by technology

At present, the drawing folding method is mainly manual folding. Before the drawing is folded, prepare a template slightly smaller than the size of the A4 drawing (generally 292*205); Sequential folding (first horizontal, then vertical); this method not only increases the labor intensity of the staff, but also has low efficiency, and cannot meet the needs of a large number of folding drawings of the Design Engineering Institute, and the existing engineering drawing folding equipment is bulky and clumsy in operation , the operation and maintenance are inconvenient, which brings certain troubles to the user for the folding work of the drawings

Embodiment 1

[0022] see figure 1 In Embodiment 1 of the present invention, the portable engineering drawing folding machine includes four parts: a frame 501, a motor 601, a transmission device, and an indentation device, wherein the transmission device includes a transmission shaft 101, a transmission drum 102, a gear 103, and an upper conveyor belt 201 , the lower conveyor belt 301, the gear teeth 401, and the indentation device includes an upper belt short-side protrusion 202, an upper belt short-side groove 203, an upper belt long-side protrusion 204, an upper belt long-side groove 205, and a lower belt short-side protrusion Lifting 303, lower belt short side groove 302, lower belt long side protrusion 305, lower belt long side groove 304, it is characterized in that four identical drive rollers 102 are divided into upper and lower groups, symmetrically arranged on the frame 501, four drive rollers 102 are parallel in pairs, upper conveyor belts 201 are set on the two drive rollers 102 ...

Embodiment 2

[0029] see figure 2 , this figure is a schematic diagram of the expansion of the conveyor belt 201 on the portable engineering drawing folding machine. In the figure, the upper belt short side protrusions 202, the upper belt short side grooves 203, the upper belt long side protrusions 204, and the upper belt are arranged on the upper conveyor belt 201. The position and distance of the groove 205 on the long side are clear at a glance. The bonding side I 206 and the bonding side II 207 belong to the same side in the actual operation process. After the bonding side I 206 and the bonding side II 207 are bonded, the upper conveyor belt 201 will form an Contiguous barrel conveyors.

Embodiment 3

[0031] see image 3 , this figure is a schematic diagram of the expansion of the lower conveyor belt 301 of the portable engineering drawing folding machine. In the figure, the lower belt short-side protrusions 203, the lower belt short-side grooves 302, the lower belt long-side protrusions 305, and the lower belt are arranged on the upper conveyor belt 301. The position and distance of the long side groove 304 are clear at a glance. The bonding side I 206 and the bonding side II 207 belong to the same side in the actual operation process. After the bonding side III 306 and the bonding side IV 307 are bonded, the lower conveyor belt 301 will form a End-to-end barrel conveyor belts.

Abstract

The invention relates to portable engineering drawing processing equipment, in particular to a portable engineering drawing folding machine. The portable engineering drawing folding machine comprisesa rack, a motor, a transmission device and an indentation device and is characterized in that four identical transmission rollers are divided into an upper group and a lower group to be symmetricallyarranged on the rack, every two four transmission rollers are parallel, an upper conveying belt is arranged on the two transmission rollers at the upper end, a lower conveying belt is arranged on thetwo transmission rollers at the lower end, a chain wheel is arranged on the same side of the four transmission shafts, gears of the upper group and the lower group of transmission rollers are engagedthrough gear teeth, the motor is installed on the other side, opposite to a transmission shaft provided with a gear, of one transmission shaft, and the stable operation of the four rollers is guaranteed under the driving of the motor. According to the portable engineering drawing folding machine, the labor intensity of workers is effectively reduced, the working efficiency is improved, and the portable engineering drawing folding machine is worthy of being popularized and used in the technical field of engineering.

Description

technical field [0001] The invention relates to portable engineering drawing processing equipment, in particular to a portable engineering drawing folding machine. Background technique [0002] Engineering drawings often have different formats and sizes, and are generally saved by folding. According to the "General Requirements for the Composition of Science and Technology Archives", the specific requirements are: (1) adopt the "accordion" folding method; (2) face the drawing inwards to reduce wear on the drawing; (4) Drawings of different amplitudes should be uniformly folded into an international standard A4 size; (5) The title column of the drawing should be exposed in the lower right corner by folding corners, etc., for easy reference. At present, the drawing folding method is mainly manual folding. Before the drawing is folded, prepare a template slightly smaller than the size of the A4 drawing (generally 292*205); Sequential folding (first horizontal, then vertical);...
