Description

Technical Field

[0001] This utility model relates to the field of cutting machines, and more specifically, to a cutting inverted adsorption and receiving platform. Background Technology

[0002] In the printing industry, paper cutters are mainly used to cut large-format printed media into the required size and shape. The lower end of the paper cutter's outlet is usually equipped with a receiving platform for collecting the printed media; the cut media falls from the outlet onto the receiving platform. However, when cutting and collecting flexible printed media such as fabric, due to their high softness, the outer ends of the printed media tend to overlap the already collected media early on, causing friction between the media and resulting in curling, arching, and rolling, which in turn affects the clarity of the printed image.

[0003] Utility model patent CN222494411U discloses a paper cutter, including a gantry, a worktable, a paper feeding mechanism, a paper pressing mechanism, a cutting mechanism, a hydraulic system, and a control display screen. The gantry is connected to the upper part of the worktable, the paper feeding mechanism is connected to the worktable, the paper pressing mechanism is connected to the upper part of the gantry, and the cutting mechanism is connected to the gantry. The hydraulic system is located on the worktable and connected to the paper feeding mechanism, the paper pressing mechanism, and the cutting mechanism. The control display screen is located on the gantry. The paper feeding mechanism includes a transmission frame, suction cups, air pipes, a vacuum generator, a drive motor, a drive wheel, a transmission belt, a driven wheel, a rotating shaft, a paper feeding roller assembly, and a conveyor belt. This paper cutter, by incorporating a vacuum suction cup structure for paper transfer, can automatically position and adsorb the paper to be cut, and deliver it to the paper feeding mechanism to the cutting position. This eliminates the need for manual alignment of the paper before placing it on the cutting worktable, avoiding the danger of the cutting blade and improving the accuracy of paper cutting. However, the paper feeding mechanism disclosed in this paper cutter requires a folding motion when the paper is collected at the discharge port, resulting in low continuity. Utility Model Content

[0004] In order to improve the continuity of printing media collection after cutting and avoid mutual friction between printing media, the technical solution adopted by this utility model is: a cutting inverted adsorption collection platform, including a support frame, a lower rotating component, an upper rotating component and a negative pressure adsorption platform. The negative pressure adsorption platform is disposed in the cavity of the upper rotary assembly and is used to gradually adsorb the printing medium onto the lower surface of the upper rotary assembly during the cutting process, and to gradually release the printing medium from the front end so that the printing medium falls gradually onto the lower rotary assembly in an inclined posture with the front end falling first. The upper rotary assembly is mounted on the support frame and located above the lower rotary assembly, and is used to pull the printing medium forward; The lower rotating assembly is mounted on the support frame and is used to receive the printing media falling from the lower surface of the upper rotating assembly and to transport the collected printing media outward.

[0005] Based on the above, the negative pressure adsorption platform is provided with several air extraction holes on its side, and several negative pressure holes are respectively opened on the upper and lower surfaces of the negative pressure adsorption platform. The negative pressure holes are connected to the air extraction holes, and a vacuum pump is connected to the air extraction holes.

[0006] Based on the above, the negative pressure holes are divided into several hole groups according to the order of opening. The extension direction of each hole group is perpendicular to the travel direction of the printing medium, and each hole group is connected to one of the air extraction holes.

[0007] Based on the above, in each of the pore groups, adjacent negative pressure pores are obliquely connected to form adsorption bands that are connected in a series of V-shapes.

[0008] Beneficial effects: By designing each group of holes as an adsorption band connected in multiple V-shapes, the adsorption range of each group of holes is increased, which facilitates the adsorption of the front end of the printing medium and avoids the defect of insufficient adsorption.

[0009] Based on the above, the lower rotary assembly includes several lower rotary belts arranged side by side, a lower pulley group for driving the lower rotary belts to rotate, and a bracket for supporting the several lower rotary belts, the bracket being disposed on the support frame; The bracket is equipped with a receiving baffle that extends out of the lower rotary belt. The receiving baffle is used to block and align the front end of the inclined falling printing medium.

[0010] Based on the above, the receiving baffle is adjustablely mounted on the bracket.

[0011] Beneficial effects: By adjusting the receiving baffle on the bracket, the position of the receiving baffle can be flexibly adjusted according to the size of each batch of printing media when collecting different batches of printing media, thereby ensuring that each batch of printing media can be arranged neatly.

[0012] Based on the above, the support frame is equipped with a bracket lifting motor and a vertical guide rail, and the bracket can be lifted and lowered on the support frame by the bracket lifting motor.

[0013] Beneficial effects: By mounting the tray on the support frame in a height-adjustable manner via a tray lifting motor, the lower rotary belt can be raised during the initial collection of printing media, shortening the falling path of the printing media and preventing it from deviating from its intended path. Simultaneously, the distance between the lower and upper rotary belts can be adjusted in real time based on the height of the collected paper stack, increasing collection capacity.

[0014] Based on the above, the upper rotary assembly includes several upper rotary belts arranged side by side, and upper pulley sets are respectively provided at both ends of the upper rotary belts, and the upper pulley sets are driven by a belt drive motor.

[0015] Based on the above, the upper surface of the negative pressure adsorption platform is lower than the upper surface of the upper rotating belt, and the lower surface of the negative pressure adsorption platform is higher than the lower surface of the upper rotating belt, so as to suspend and adsorb the printing medium on the lower surface of the upper rotating belt.

[0016] Beneficial effects: While ensuring that the printing media is stably adsorbed on the lower surface of the upper rotating belt, it can also reduce the friction between the printing media and the negative pressure adsorption platform, thus avoiding damage to the printing media.

[0017] This invention represents a substantial advancement over existing technologies. Specifically, the cutting and inverting adsorption receiving platform provided by this invention progressively adsorbs the printing medium onto the lower surface of the upper rotating component during the cutting process. Then, after the upper rotating component pulls the printing medium to a certain position, it is progressively released from the front end, allowing the printing medium to fall onto the lower rotating component in a tilted manner with the front end falling first. This ensures that the cut printing medium falls freely at an angle, avoiding direct friction and preventing phenomena such as curling, arching, or rolling, thus improving the clarity of the printed image. Simultaneously, because the upper rotating component rotates in a circular motion, the reversing operation of existing gripping mechanisms is avoided, achieving continuous material receiving.

[0018] Furthermore, by designing each group of holes as an adsorption band connected in multiple V-shapes, the adsorption range of each group of holes is increased, which facilitates the adsorption of the front end of the printing medium and avoids the defect of insufficient adsorption.

[0019] Furthermore, by vertically mounting the tray on the support frame via a tray lifting motor, the lower rotary belt can be raised during the initial collection of printing media, shortening the falling path of the printing media and preventing it from deviating from its designated path. Simultaneously, the distance between the lower and upper rotary belts can be adjusted in real time based on the height of the collected paper stack, increasing collection capacity. Additionally, the collected printing media can be conveyed outwards, improving the neatness and efficiency of the collection process.

[0020] Furthermore, by adjusting the receiving baffle on the bracket, the position of the receiving baffle can be flexibly adjusted according to the size of each batch of printing media when collecting different batches of printing media, thereby ensuring that each batch of printing media can be neatly arranged.

[0021] Therefore, this cutting and inverted adsorption collection platform improves the continuity of collection after cutting the printing media and avoids mutual friction between the printing media. Attached Figure Description

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0028] Example 1 This embodiment provides a cutting and inverting adsorption collection platform, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the assembly includes a support frame 12, a lower rotating assembly, an upper rotating assembly, and a negative pressure adsorption platform 7. The negative pressure adsorption platform 7 is disposed within the cavity of the upper rotating assembly and is used to progressively adsorb the printing medium 2 onto the lower surface of the upper rotating assembly during the cutting process, and to progressively release the printing medium 2 from the front end, so that the printing medium 2 falls progressively onto the lower rotating assembly in an inclined posture with the front end falling first.

[0029] The upper rotating assembly is mounted on the support frame 12 and located above the lower rotating assembly, and is used to pull the printing medium 2 forward. The lower rotating assembly is mounted on the support frame 12 and is used to receive the printing medium 2 that falls from the lower surface of the upper rotating assembly and to convey the collected printing medium 2 outward.

[0030] Specifically, such as Figure 2 As shown, the negative pressure adsorption platform 7 has several suction holes on its side. Several negative pressure holes are also formed on the upper and lower surfaces of the negative pressure adsorption platform. These negative pressure holes are connected to the suction holes, and a vacuum pump 13 is connected to the suction holes.

[0031] The negative pressure holes are divided into several groups according to their opening sequence. The extension direction of each group of holes is perpendicular to the travel direction of the printing medium 2, and each group of holes is connected to one of the suction holes. In each group of holes, adjacent negative pressure holes are obliquely connected to form multiple V-shaped adsorption bands connected in sequence.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the lower rotary assembly includes several lower rotary belts 9 arranged side by side, a lower pulley group 15 for driving the lower rotary belts 9 to rotate, and a bracket 10 for supporting the lower rotary belts 9. The bracket 10 is mounted on the support frame 12. A receiving baffle 6 is provided on the bracket 10, extending beyond the lower rotary belts 9. The receiving baffle 6 is used to block and align the front end of the inclined falling printing medium 2.

[0033] The upper rotary assembly includes several upper rotary belts 8 arranged side by side. Each end of the upper rotary belt 8 is provided with an upper pulley group 14, and the upper pulley group 14 is connected to a belt drive motor.

[0034] Example 2 This embodiment provides a cutting and inverting adsorption collection platform. The main difference from Embodiment 1 is that in this embodiment, the collection baffle 6 is adjustablely mounted on the bracket 10. That is, by adjusting the collection baffle on the bracket, the position of the collection baffle can be flexibly adjusted according to the size of each batch of printing media when collecting different batches, thereby ensuring that each batch of printing media is neatly arranged.

[0035] Example 3 This embodiment provides a cutting and inverting adsorption and collection platform. The main difference from Embodiment 1 is that in this embodiment, the support frame 12 is provided with a bracket lifting motor 11 and a vertical guide rail. The bracket 10 can be lifted and lowered on the support frame 12 through the bracket lifting motor 11.

[0036] Specifically, by raising and lowering the bracket on the support frame 12 via the bracket lifting motor, the lower rotary belt can be raised during the initial collection of printing media, shortening the falling path of the printing media and preventing it from deviating from its intended path. Simultaneously, the distance between the lower and upper rotary belts can be adjusted in real time based on the height of the collected paper stack, increasing collection capacity.

[0037] Example 4 This embodiment provides a cutting and inverting adsorption and collection platform. The main difference from Embodiment 1 is that, in this embodiment, the upper surface of the negative pressure adsorption platform 7 is lower than the upper surface of the upper rotating belt 8. The lower surface of the negative pressure adsorption platform 7 is higher than the lower surface of the upper rotating belt 8, so as to suspend and adsorb the printing medium on the lower surface of the upper rotating belt.

[0038] Specifically, the working steps of the cutting and inverting adsorption material collection platform provided by this utility model are as follows: First, the inverted suction and collection platform is placed on one side of the discharge port of the paper cutter 1. The negative pressure suction platform 7 generates negative pressure to attract the front end of the printing medium 2, and the belt drive motor is started to rotate the upper rotary belt 8, pulling the printing medium 2 forward. During the pulling process, the paper cutter uses the longitudinal cutter 3 to cut the printing medium 2 longitudinally.

[0039] After the printing medium 2 is pulled out to a certain length, the paper cutter 1 uses the transverse cutter 4 to cut the printing medium 2 transversely. Then, after the negative pressure of the negative pressure adsorption platform 7 is gradually cut off, the printing medium 2 is tilted and falls onto the lower rotary belt 9. After the paper stack 5 accumulates to a certain thickness, the lower rotary belt 9 and the bracket 10 descend. When the paper stack 5 has accumulated to a certain height, the lower rotary belt 9 is started to rotate, conveying the paper stack 5 outward.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
