Express face sheet cutting equipment

technical field

The invention relates to the technical field of cutting equipment, and specifically discloses an express noodle sheet cutting equipment.

Background technique

With the rapid development of e-commerce, the express delivery industry has also flourished, and a large number of packages need to be delivered to buyers through logistics express. On the surface of the express package, there is often a express sheet posted. The so-called express bill of lading refers to the document used by the express industry to record relevant information such as sender, recipient, product weight and price during the process of delivering goods. During the production process of the express delivery list, it is necessary to cut the excess paper to meet the use requirements of the express delivery list. At present, when cutting express delivery sheets, most of them are cut by hand, and in the cutting process, auxiliary equipment is needed to flatten the express delivery sheets before cutting, or the staff manually flatten the express delivery sheets before cutting. In this way, not only the cutting work intensity of the express delivery list is high and the cutting efficiency is low, but also the problem of unevenness of the express delivery list after cutting due to the uneven level of the staff will lead to the scrapping of the express delivery list and increase the production of the enterprise. cost.

Contents of the invention

The present invention intends to provide an express delivery bill cutting device to solve the problems of high work intensity and easy scrapping of the express delivery bill when cutting the existing express delivery bill.

In order to achieve the above object, the basic solution of the present invention is: express noodle single cutting equipment, including a frame and a workbench, the frame is fixedly connected with a motor, a fixed block and a lower knife mechanism, and the output end of the motor is fixedly connected with a first Rotating shaft, the first rotating shaft is coaxially fixedly connected with a turntable and a sector gear, the turntable is fixedly connected with a support rod, and the end of the support rod away from the center of the turntable is fixedly connected with a protrusion; the fixed block is rotatably connected with a second rotating shaft, the second The two rotating shafts are coaxially fixedly connected with a rotating block, and the rotating block is provided with four chutes that can slide and cooperate with the protrusions. Adjacent chutes are perpendicular to each other, and the edges of the turning blocks between adjacent chutees are matched with the edges of the turntable. The sector gear is meshed with a rack, the rack is slidably connected to the frame, the knife lowering mechanism includes a first spring fixedly connected to the frame, and one end of the first spring close to the workbench is fixedly connected to a vertical shaft, A connecting rod is fixedly connected between the vertical shaft and the rack, and the vertical shaft is fixedly connected with a cutter for cutting express delivery sheets. The side walls opposite to the vertical shaft are provided with first grooves, and the first grooves are slidingly connected with L-shaped slide bar, the second spring is fixedly connected between the L-shaped slide bar and the inner wall of the first groove, and one end of the L-shaped slide bar close to the workbench is fixedly connected with a pressing plate, and the pressing plate is provided with a passage for the tool to pass through; The end of the workbench far away from the fixed block is fixedly connected with a vertical plate, the workbench is slidably connected with a frame for placing express delivery sheets, and a string is fixedly connected between the frame and the second rotating shaft, and the end of the frame far away from the fixed block is connected to the vertical plate. A third spring is fixedly connected between the plates.

The working principle of this basic scheme is: use the motor to drive the turntable to rotate, and the support rod fixedly connected with the turntable will rotate together with it. It starts to rotate under the action of the second rotating shaft, so that the second rotating shaft rotates in the same direction, and the thin rope fixedly connected to the second rotating shaft begins to wind around the second rotating shaft, and the thin rope between the second rotating shaft and the frame becomes shorter. Therefore, the frame The body starts to slide towards the fixed block, during which the third spring receives tension and has an elastic recovery force opposite to the direction of the tension. When the pole rotates through 90°, the protrusion on the pole is separated from the chute of the rotary block. At this time, the edge of the turntable matches the edge of the rotary block, and the rotary block no longer rotates, and the frame is still on the workbench. . During the above process, the sector gear on the first shaft meshes with the rack, the rack slides, and the vertical axis fixedly connected to the rack through the connecting rod moves in the direction of the frame. Apply pressure to the express sheet, flatten the express sheet, the vertical axis continues to move, compress the second spring, the knife fixedly connected to the vertical axis passes through the channel of the pressure plate to cut the express sheet, and the first spring is under tension during the process It has an elastic recovery force opposite to the direction of the pulling force. When the sector gear rotates and no longer meshes with the rack, under the action of the elastic restoring force of the first spring, the vertical shaft and the pressing plate return to their original positions. At this time, the pole rotates through 360°, and the protrusion on the pole slides and cooperates with the next chute of the rotary block again, and then drives the rotary block to rotate. The above process is repeated continuously to realize the automatic cutting of the express delivery list.

The beneficial effects of this basic plan are:

1. In this basic scheme, by setting protrusions on the turntable, four chutes that can cooperate with the protrusions are set in the turn block, and the adjacent chutes are perpendicular to each other to realize the intermittent sliding of the frame on the workbench , and the sliding distance of the frame is consistent each time, which can realize the uniform cutting of the express delivery list in the frame, ensure the uniform size of the express delivery list after cutting, and improve the cutting quality.

2. In this basic scheme, the sector gear coaxially connected with the turntable and the rack mesh with each other, and the rack drives the vertical axis to move in the direction of the frame through the connecting rod, so as to realize the automatic cutting of the express delivery list, improve the work efficiency and reduce the workload of the staff. Labor intensity. Moreover, before the cutter cuts the express delivery sheet, the pressure plate in the lower knife mechanism first flattens the express delivery sheet, so as to realize the first flattening and then cutting, so as to avoid the position movement of the express delivery sheet during the cutting process, resulting in uneven cutting surface. Thereby reducing the amount of scrapped express bills and reducing production costs.

3. In this basic scheme, a third spring is set between the frame and the vertical plate. On the one hand, the third spring can limit the sliding distance of the frame, so as to prevent the frame from moving straight to The fixed block slides in the direction to ensure that the sliding distance of the frame is equal to the reduction in the length of the string between the second rotating shaft and the frame; on the other hand, the reset of the frame can be realized to further improve the automation of the device.

Further, the second rotating shaft is provided with an annular groove, the inner wall of the annular groove is fixedly connected with a rubber layer, and one end of the string is bound in the annular groove. In this way, the thin rope is regularly wound in the annular groove, and the rubber layer can increase the friction coefficient between the annular groove and the thin rope, thereby increasing the static friction between the thin rope and the annular groove, and avoiding that the thin rope cannot be wound The situation in the annular groove.

Further, the string is made of ultra-high-strength polyethylene fiber material, which has outstanding impact resistance and cutting resistance, and has a long flex life.

Further, a push plate is slidably connected in the frame, and a fourth spring is fixedly connected between the push plate and the inner wall of the frame. In this way, the frame body can adapt to a stack of express delivery sheets of different sizes, realize cutting of a stack of express delivery sheets of different sizes, and improve the use range of the device.

Further, the central angle of the sector gear is 180°, the angle between the central axis of the sector gear and the central axis of the strut is 135°, and the teeth of the sector gear are located on the side away from the rack. When the sector gear turns 180°, the sector gear no longer engages with the rack, and the protrusion on the turntable turns 270° at this time, the protrusion does not cooperate with the chute of the turn block, that is, the frame is still in a static state , It can ensure that the lower knife mechanism has enough time to return to the original position after cutting the express delivery sheet, so as to avoid the movement of the frame during the tool reset process, the cutter cutting the express delivery sheet, and causing the express delivery sheet to be scrapped.

The central angle of the sector gear 4 is 180°, the angle between the central axis of the sector gear 4 and the central axis of the strut 5 is 135°, and the teeth of the sector gear 4 are located on the left side. The sector gear 4 is meshed with a rack 7, and the rack 7 is slidably connected to the frame. The fixed block 8 is rotatably connected with a second rotating shaft 9, and the second rotating shaft 9 is provided with an annular groove, and the inner wall of the annular groove is fixedly connected with a rubber layer. The second rotating shaft 9 is coaxially fixedly connected with a turning block 10, and the turning block 10 is provided with four chutes 11 that can slide and cooperate with the protrusion 6. The adjacent chute 11 is perpendicular to each other, and the turning block between the adjacent chute 11 10 edges cooperate with rotating disk 3 edges.

As shown in FIG. 3 , the lower knife mechanism 12 includes a first spring 13 fixedly connected to the frame, a vertical shaft 14 is fixedly connected to the lower end of the first spring 13 , and a connecting rod 15 is fixedly connected between the vertical shaft 14 and the rack 7 . The lower end of the vertical shaft 14 is fixedly connected with a cutter 16 for cutting express delivery sheets, and the opposite side walls of the vertical shaft 14 are provided with first grooves 17, and L-shaped slide bars 18 are slidably connected in the first grooves 17. A second spring 19 is fixedly connected between the shaped slide bar 18 and the upper wall of the first groove 17 . The lower ends of the two L-shaped slide bars 18 are fixedly connected with a pressing plate 20, and the pressing plate 20 is provided with a passage for the cutter 16 to pass through.

The right end of the workbench 1 is fixedly connected with a vertical plate 21, and the workbench 1 is slidably connected with a frame 22 for placing express delivery sheets. The left end of the frame 22 is fixedly connected with a string 23, which is made of ultra-high-strength polyethylene fiber Made, the left end of the string 23 is bound in the annular groove of the second rotating shaft 9, and the third spring 24 is fixedly connected between the right end of the frame body 22 and the riser 21. A push plate 25 is slidably connected in the frame body 22 , and two fourth springs 26 are fixedly connected between the right side of the push plate 25 and the inner wall of the frame body 22 .

During specific work, slide the push plate 25 to the right, compress the fourth spring 26, place a stack of express delivery sheets in the frame body 22, release the push plate 25, and under the leftward elastic restoring force of the fourth spring 26, The push plate 25 exerts a thrust to the left on the express delivery sheets, and this stack of express delivery sheets is fixed in the frame body 22. Start the motor 2, the first rotating shaft starts to rotate clockwise, and the turntable 3 fixedly connected to the first rotating shaft starts to turn clockwise, and the protrusion 6 on the pole 5 slides and fits with the chute 11 of the turn block 10 to drive the turntable The block 10 rotates counterclockwise, thereby driving the second rotating shaft 9 to rotate counterclockwise, and the string 23 bound in the annular groove of the second rotating shaft 9 begins to be wound in the annular groove in an orderly manner. At this time, the rubber layer can increase the thickness The friction between the rope 23 and the annular groove prevents the string 23 from slipping. Therefore, the string 23 between the second rotating shaft 9 and the frame body 22 becomes shorter, and the frame body 22 starts to slide to the left, during which the third spring 24 is pulled to the left and has an elastic recovery force to the right.
