Description

Technical Field

[0001] This utility model belongs to the field of sponge cutting technology, specifically a cutting device for processing sponge headrests. Background Technology

[0002] Sponges are porous materials with good water absorption properties, which can be used to clean items. Commonly used sponges are made of wood cellulose fibers or foamed plastic polymers. Sponges are used in various industries, including the automotive industry, battery industry, cosmetics industry, bra and underwear manufacturing industry, and high-end furniture manufacturing industry. To adapt to different applications, sponges usually need to be cut.

[0003] In the continuous cutting of sponges, existing cutting devices transport the sponge to the cutting blade, complete measurement, calibration, and positioning, then the drive mechanism moves the blade downwards to complete the cutting. The blade then moves upwards to detach from the sponge, releases the lock, and continues feeding to complete measurement, calibration, and positioning. The drive mechanism then moves the blade downwards again to cut. This process is repeated to complete the continuous segmented cutting of large pieces of sponge, resulting in extremely low efficiency. This is especially true when multiple repetitive fixings are required, and when the drive mechanism cuts through the blade, each cut requires a complete lifting and reciprocating motion, which consumes a lot of energy and is inefficient. Therefore, it is necessary to develop a cutting device for processing sponge headrests to address the shortcomings of existing technologies. Summary of the Invention

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5As shown, this utility model provides a cutting device for processing sponge headrests, including a feeding rack 1, a conveying trough 2 at the top of the feeding rack 1, a feeding belt 3 at one end of the inner cavity of the conveying trough 2, a discharging belt 4 at the other end of the inner cavity of the conveying trough 2, a gap between the feeding belt 3 and the discharging belt 4, two symmetrical flow guiding support components 5 located between the feeding belt 3 and the discharging belt 4 inside the conveying trough 2, a support frame 6 located directly above the flow guiding support components 5 at the top of the feeding rack 1, a lifting rod 7 installed at the top of the inner cavity of the support frame 6, a positioning and holding component 8 fixedly connected to the bottom of the movable end of the lifting rod 7, a cutting tool 9 inside the positioning and holding component 8, and a lifting system inside the support frame 6. The lifting system pushes the cutting tool 9 past the positioning and holding component 8 to cut the sponge, and finally moves it between the two flow guiding support components 5. The cutting tool 9 includes a tool holder 91 disposed inside the positioning and holding assembly 8. The front and rear ends of the tool holder 91 are respectively provided with the front and rear sides of the inner cavity of the support frame 6, and both are connected to the lifting system. The top and bottom of the tool holder 91 are provided with cutting edges 92. Due to the setting of the cutting tool 9, driven by the tool holder 91, through the two cutting edges 92 at its top and bottom, with the cooperation of the flow guide support assembly 5, the positioning and holding assembly 8, the lifting rod 7 and the transmission system, the cutting tool 9 can complete two cuts with each lifting and lowering, which not only greatly improves the cutting efficiency, but also reduces the cutting drive energy consumption, achieving the effect of energy saving and emission reduction.

[0018] The bottom of the feeding rack 1 is equipped with a conveying system. The output end of the conveying system extends into the interior of the conveying trough 2. The conveying trough 2 and the feeding belt 3 are connected by a number of evenly distributed support drive rollers 16. The rear end of the support drive rollers 16 is connected to the front end of the output end of the conveying system. Due to the setting of the support drive rollers 16, the feeding belt 3 and the unloading belt 4 can be driven in cooperation with the conveying system, so that the feeding belt 3 and the unloading belt 4 can run synchronously to achieve the purpose of simultaneous feeding and unloading. At the same time, the middle section of the feeding belt 3 and the unloading belt 4 can be supported to ensure that the sponge on the top remains stable.

[0019] The flow guide support assembly 5 includes a support plate 51 fixedly installed inside the conveying trough 2. A flow guide slope 52 is provided on one side of the support plate 51 near the middle of the gap between the feeding belt 3 and the unloading belt 4. The outer surface of the flow guide slope 52 is smooth. Due to the setting of the flow guide slope 52, it can be ensured that the lower end of the cutter 9 can be accurately inserted into the gap between the feeding belt 3 and the unloading belt 4. This prevents the bottom of the cutter 9 from abutting against the feeding belt 3 and the unloading belt 4, and also avoids the lower end of the cutter 9 from shifting and affecting the cutting accuracy.

[0020] The top of the support plate 51 is movably embedded with several evenly distributed conveyor rollers 53, the top of which is flush with the top of the feeding belt 3 and the unloading belt 4. Due to the setting of the conveyor rollers 53, the sponge can be supported in cooperation with the support plate 51 so that the sponge can continue to be conveyed in cooperation with the feeding belt 3 and the unloading belt 4. At the same time, it can be used in cooperation with the positioning and holding component 8 to ensure that the sponge remains stable during cutting, so as to ensure cutting accuracy.

[0021] The positioning and holding assembly 8 includes a positioning and holding protective plate 81 fixedly connected to the bottom of the movable end of the lifting rod 7. The positioning and holding protective plate 81 has a hollow structure and a through-hole 83 is opened at the bottom of the positioning and holding protective plate 81. The cutter 9 moves to the outside of the positioning and holding assembly 8 through the through-hole 83. Both the front and rear ends of the cutter 9 pass through the positioning and holding protective plate 81 and are connected to the lifting system. Several pressing and anti-slip toothed strips 82 located on the left and right sides of the through-hole 83 are fixedly connected to the bottom of the positioning and holding protective plate 81. The bottom of the pressing and anti-slip toothed strips 82 abuts against the top of the sponge.

[0022] The support frame 6 has a limiting groove 10 on both the front and rear sides of its inner cavity. The upper part of the support frame 6 has a hollow structure. The lifting system is connected to the front and rear ends of the tool holder 91 through the interior of the support frame 6 and the limiting groove 10. The front and rear sides of the inner cavity of the support frame 6 are provided with limiting slots 15 located on the left and right sides of the limiting slide groove 10. The front and rear ends of the positioning and holding protective plate 81 are fixedly connected with two left and right limiting sliders, and the limiting sliders are slidably engaged in the inside of the limiting slots 15.

[0023] The lifting system consists of a drive motor 13, a transmission belt 14, two transmission screws 12, and a limiting sleeve 11. The two limiting sleeves 11 are slidably engaged in the two limiting grooves 10, and the two transmission screws 12 are threaded into the two limiting sleeves 11. The lower end of the transmission screw 12 is rotatably connected to the bottom of the inner cavity of the limiting groove 10, and the upper end of the transmission screw 12 passes through the limiting groove 10 and extends into the hollow structure at the upper end of the support frame 6, and is fixedly connected to a pulley. The transmission belt 14 is set in the hollow structure at the upper end of the support frame 6 and is driven and sleeved on the two pulleys. The drive motor 13 is fixedly installed on the top of the support frame 6, and the lower end of the output shaft of the drive motor 13 extends into the hollow structure at the upper end of the support frame 6 and is fixedly connected to the top of one of the pulleys.

[0024] The positioning and holding component 8 is equipped with a visual positioning system and a pressure sensor below it. The support frame 6 is also equipped with a control component on its front side. The control component is electrically connected to the lifting rod 7, the drive motor 13 and the visual positioning system. The pressure sensor transmits signals between itself and the control system.

[0025] Working principle and usage process of this utility model: After starting the equipment, place the sponge to be cut on the feeding belt 3. With the cooperation of the support drive roller 16, the feeding belt 3 and the unloading belt 4 will move simultaneously. At this time, with the cooperation of the vision positioning system, the sponge is conveyed to the area below the positioning and holding assembly 8. Moreover, with the cooperation of the two guide support assemblies 5, the front end crosses the gap between the feeding belt 3 and the unloading belt 4 and moves to the top of the unloading belt 4, ensuring that the cutter 9 is directly above the cutting point. At this time, the conveying system stops running, and the lifting rod 7 and the drive motor 13 run simultaneously, pushing the positioning and holding assembly respectively. The component 8 and the cutter 9 move down synchronously. With the cooperation of the pressure sensor, when the pressure-holding anti-slip toothed rack 82 at the bottom of the positioning and holding protective plate 81 presses against the top of the sponge, the lifting rod 7 stops running, while the drive motor 13 continues to run. With the cooperation of the limiting slide groove 10, the limiting slide sleeve 11, the transmission screw 12 and the transmission belt 14, the cutter holder 91 continues to move down and cuts the sponge through the blade 92 at its bottom until the cutter 9 completely penetrates to the bottom of the sponge and is inserted into the gap between the feeding belt 3 and the unloading belt 4 with the cooperation of the two flow guide support components 5. At this point, the drive motor 13 stops running, and the lifting rod 7 shortens and drives the positioning and holding assembly 8 to rise until the bottom of the holding anti-slip rack 82 is detached from the sponge. Then the conveying system moves again and continues to convey the sponge, so that its new front end continues to pass over the cutter 9 until, with the cooperation of the vision positioning system, the new cutting point moves to be directly above the cutter 9. At this time, the lifting rod 7 continues to move and pushes the positioning and holding assembly 8 down, so that the bottom of the holding anti-slip rack 82 abuts against the top of the sponge again. Then the drive motor 13 starts to run in reverse and, through the cooperation of the limiting slide groove 10, the limiting slide sleeve 11, the transmission screw 12 and the transmission belt 14, makes the cutter holder 91 rise and cut the sponge through the blade 92 at its top until the cutter 9 completely penetrates to the top of the sponge. In this way, a cycle of two cuts is completed. Repeating the above cycle can complete the cutting at double the speed.
