Description

Technical Field

[0001] This utility model relates to the field of sponge production technology, specifically to a cutting device for sponge production with a non-displaceable cutter. Background Technology

[0002] Sponge is a porous material with good water absorption and is widely used in the automotive industry, battery industry, cosmetics industry, bra and underwear manufacturing industry, and high-end furniture manufacturing industry. The strip cutting device in sponge production is one of the key pieces of equipment in the sponge manufacturing process. It is used to cut continuous sponge material into strips of a specific width or length for further processing or use.

[0003] The utility model patent with authorization announcement number CN222371688U discloses a cutting device for sponge production with non-displaceable cutter, including a cutting device platform, an adjustable equidistant cutting assembly located on the top of the cutting device platform, and a conveyor roller shaft height adjustment assembly located inside the cutting device platform.

[0004] As shown in the above-mentioned utility model, the existing strip cutting device, through the set conveyor roller height adjustment component, can adapt to the conveying requirements of sponges of different thicknesses, ensuring the stability and reliability of the sponge strip cutting process, avoiding the possibility of sponge material getting stuck between the rollers, causing conveyor belt blockage, and reducing the wear of sponge material and rollers, thus extending the service life of the equipment. However, the blade spacing of the traditional strip cutting device is a fixed width, relying on manual replacement of different specifications of blades or molds to change the width of the sponge strips. It cannot be quickly adjusted according to real-time production needs, which seriously affects production efficiency and is difficult to adapt to the flexible production needs of small batches and multiple specifications. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a cutting device for sponge production with a non-displaceable cutter, thus solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for sponge production with a non-displaceable cutter, comprising:

[0007] The frame has a conveyor belt inside for conveying sponges, and a mounting frame is provided in the middle of the upper surface of the frame for mounting the cutting mechanism and the pressing mechanism.

[0008] Two clamping components are provided, which are symmetrically arranged on both sides of the inner cavity of the mounting frame to clamp the sponge strip.

[0009] A connector is mounted on a mounting frame and is used to connect a drive mechanism on the mounting frame. The connector is designed to be detachable to facilitate the replacement of the cutting mechanism on the drive mechanism.

[0010] A cutting component, which is mounted on a drive mechanism on a mounting frame, is used to cut the sponge flat.

[0011] Preferably, the drive mechanism includes a motor fixed to one side of the mounting bracket, a drive shaft fixed to the output end of the motor, a connecting shaft fixed to the end of the drive shaft, and guide grooves provided on the upper and lower sides of the drive shaft and the connecting shaft.

[0012] Preferably, two symmetrically distributed dovetail grooves are provided on the inner walls of both sides of the mounting frame, and an empty groove is provided in the middle of the other side of the mounting frame. A retaining groove is provided in the middle of both ends of the empty groove, and a limiting plate is provided on the upper outer side of the retaining groove. One end of the limiting plate is movably connected to the mounting frame through a bearing.

[0013] Preferably, the clamping component includes a telescopic cylinder, the output end of which is connected to a movable plate. The movable plate is in contact with the inner wall of the mounting frame. A dovetail slider is fixed on one side of the movable plate. The dovetail slider is located in the dovetail groove and is used to drive the movable plate to move vertically up and down. A clamping roller is movably connected between two corresponding movable plates through a connecting rod and a bearing for clamping the sponge.

[0014] Preferably, the connector includes a connecting plate, both ends of which are located in slots. The outer side of the connecting plate is in contact with a limiting plate. A connecting block is fixed in the middle of the connecting plate. A locking block is movably connected to the inner side of the connecting block via a bearing.

A threaded groove is opened through one side of the connecting sleeve. A limiting screw is connected to the threaded groove through internal and external threads. The limiting screw cooperates with the drive shaft to limit the position of the connecting sleeve.

[0016] Beneficial effects

[0017] This invention provides a cutting device for sponge production with a non-displaceable cutter. Compared with the prior art, it has the following advantages:

[0018] 1. This non-displaceable cutting equipment for sponge production can adjust the spacing between adjacent cutters in a short time by cooperating with the guide block of the cutting part and the guide groove of the transmission shaft. There is no need to stop the machine to change the cutter. The position is locked by the limit screw to ensure that the cutter has no displacement during high-speed cutting, realizing "adjust and cut immediately". This significantly improves the production efficiency of multiple specifications. The telescopic cylinder of the clamping part drives the clamping roller to adaptively adjust the pressure. Combined with the stable guidance of the dovetail slider, it can keep sponges of different thicknesses flat and convey them, meeting the requirements of high-precision cutting.

[0019] 2. This non-shifting cutting equipment for sponge production features a detachable connecting structure. When replacing the cutter or repairing the drive mechanism, it can be quickly disassembled by simply rotating the limit plate. At the same time, the pressure roller is connected to the movable plate through bearings and can rotate freely with the sponge conveyor, reducing friction loss. Furthermore, the height adjustment of the conveyor roller shaft is achieved through the transmission of the lead screw body and the helical gear set, enabling precise electric or manual adjustment. This significantly reduces the intensity of manual operation and adjustment errors, ensuring stable conveying and cutting of sponges of different thicknesses. Structurally, it solves the core problems of inconvenient maintenance and poor adaptability of traditional devices. Attached Figure Description

Detailed Implementation

[0027] 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.

[0028] Please see Figure 1-6 This utility model provides two technical solutions:

[0029] First embodiment: A cutting device for sponge production with non-displaceable cutter, comprising a frame 1, a clamping component 2, a connecting component 3, and a cutting component 4.

[0030] Specifically, the frame 1 is equipped with a conveyor belt 11 for conveying sponges. The upper surface of the frame 1 is equipped with a mounting frame 12 for mounting the cutting mechanism and the pressing mechanism. The drive mechanism on the mounting frame 12 includes a motor 13 fixed on one side of the mounting frame 12. The output end of the motor 13 is fixed with a drive shaft 14. The end of the drive shaft 14 is fixed with a connecting shaft 16. Guide grooves 17 are provided on both the upper and lower sides of the drive shaft 14 and the connecting shaft 16. Two symmetrically distributed dovetail grooves 15 are provided on the inner walls of both sides of the mounting frame 12. A hollow groove 18 is provided in the middle of the other side of the mounting frame 12. A slot 19 is provided in the middle of both ends of the hollow groove 18. A limit plate 110 is provided on the upper outer side of the slot 19. One end of the limit plate 110 is movably connected to the mounting frame 12 through a bearing.

[0031] Specifically, there are two clamping components 2, which are symmetrically arranged on both sides of the inner cavity of the mounting frame 12 to clamp the sponge strip. The clamping component 2 includes a telescopic cylinder 21, and the output end of the telescopic cylinder 21 is connected to a movable plate 22. The movable plate 22 is in contact with the inner wall of the mounting frame 12. A dovetail slider 23 is fixed on one side of the movable plate 22. The dovetail slider 23 is located in the dovetail groove 15 and is used to drive the movable plate 22 to move vertically up and down. The two corresponding movable plates 22 are movably connected to a clamping roller 24 through a connecting rod and a bearing to clamp the sponge. The telescopic cylinder 21 drives the movable plate 22 to move up and down, which in turn drives the clamping roller 24 to move up and down, adjusting the degree of clamping of the sponge and adapting to sponges of different thicknesses.

[0032] More specifically, the connector 3 is mounted on the mounting bracket 12 and is used to connect the drive mechanism on the mounting bracket 12. The connector 3 is designed to be detachable, which facilitates the replacement of the cutting mechanism on the drive mechanism. The connector 3 includes a connecting plate 31, both ends of which are located in the slot 19. The outer side of the connecting plate 31 is in contact with the limiting plate 110. The limiting plate 110 limits both ends of the connecting plate 31 in the slot 19. At the same time, rotating the limiting plate 110 can quickly release the limiting of the connecting plate 31. A connecting block 32 is fixed in the middle of the connecting plate 31. A locking block is movably connected to the inner side of the connecting block 32 through a bearing. A slot 33 is provided on the locking block. The slot 33 is adapted to one end of the connecting shaft 16. Both the slot 33 and the connecting shaft 16 are polygonal structures. The transmission shaft 14 is connected to the connecting block 32 through the connecting shaft 16, which provides support for the connecting shaft 16 and improves the stability of the rotation of the connecting shaft 16.

[0033] The second embodiment differs from the first embodiment in that the cutting component 4 is mounted on the drive mechanism of the mounting bracket 12. The cutting component 4 includes a connecting sleeve 41 sleeved on the outside of the drive shaft 14. A cutter 42 is fixed on the outer side of one end of the connecting sleeve 41 for flat cutting of the sponge. Guide blocks 43 are fixed on the inner walls of both the upper and lower ends of the connecting sleeve 41. The guide blocks 43 are located in the guide groove 17, so that the drive shaft 14 can drive the connecting sleeve 41 to rotate, and at the same time, the connecting sleeve 41 can move horizontally on the drive shaft 14 to adjust the distance between two adjacent cutters 42, thereby adjusting the cutting width of the sponge strip. A threaded groove 44 is provided through one side of the connecting sleeve 41. A limiting screw 45 is connected in the threaded groove 44 through internal and external threads. The limiting screw 45 cooperates with the drive shaft 14 to limit the connecting sleeve 41.

[0034] When the device is in operation, the sponge roll or sheet is placed on the conveyor belt 11 of the frame 1. The conveyor belt 11 is transported to the mounting frame 12 at a constant speed to ensure that the sponge enters the cutting area smoothly. The telescopic cylinder 21 is activated, which drives the movable plate 22 to move vertically along the dovetail slide 15 (the dovetail slider 23 cooperates with the slide 15 for guidance). This drives the pressure roller 24 to press down onto the sponge surface. The pressure roller 24 is connected to the movable plate 22 through the bearing and can rotate freely to adapt to the displacement during sponge transport. At the same time, it applies uniform pressure to prevent the sponge from sliding or deforming during cutting. Before operation, according to the target sponge strip width, the limiting screw 45 of the cutting piece 4 is manually loosened, and the connecting sleeve 41 is slid along the guide groove 17 of the drive shaft 14 (the guide block 43 is embedded in the groove to ensure that there is no deviation in horizontal movement). The distance between adjacent cutters 42 is adjusted. After adjustment, the limiting screw 45 is tightened. The position of the connecting sleeve 41 is fixed by the cooperation between the screw groove 44 and the drive shaft 14 to ensure that the distance between the cutters 42 is stable during the cutting process. Next, the motor 13 is started. The motor 13 drives the connecting sleeve 41 to rotate at high speed through the transmission shaft 14. The cutter 42 rotates synchronously with the connecting sleeve 41 to form a circumferential cutting motion. The connecting plate 31 of the connector 3 is embedded in the slot 19 and locked by the limiting plate 110 to improve the stability of the drive system. The sponge enters the mounting frame 12 under the drive of the conveyor belt 11. After the pressure roller 24 pre-presses it, the high-speed rotating cutter 42 contacts the sponge surface and achieves drag-free cutting through the sharp blade.

[0035] When it is necessary to replace the cutter 42 or adjust the cutting mode, rotate the limit plate 110 to release the lock, remove the connecting plate 31 of the connector 3, and the entire cutting assembly can be quickly disassembled to adapt to the cutting needs of different specifications of sponges. Furthermore, all content not described in detail in this manual is prior art known to those skilled in the art, and the model parameters of each electrical component are not specifically limited; conventional equipment can be used.
