Description

Technical Field

[0001] This invention relates to the field of sponge cutting machinery, specifically to a sponge cutting and trimming machine. Background Technology

[0002] Traditionally, sponge cutting machines use single-edged ring cutters. To cut rectangular sponges, the cutter needs to be twisted 180 degrees to make a cut and then back. Without twisting, the cutter stops working after one stroke, resulting in lower efficiency and failing to meet production needs. The standard twist is 180 degrees. The greater the twisting deformation of the ring cutter, the longer the vertical height of the ring cutter needs to be to ensure proper twisting and minimize damage to the cutter. This results in a higher platform height for current sponge cutting machines, typically around 1 meter, leading to a larger space and larger size for the sponge cutting device. Summary of the Invention

[0003] This invention proposes a sponge cutting and trimming machine, which is ingeniously designed, easy to use, and has outstanding cutting effect on rectangular sponges, resulting in a lower overall height and a longer tool life.

[0004] The technical solution of the present invention:

[0005] A sponge cutting and trimming machine includes a conveying platform, a gantry frame, and a ring cutter mechanism. The conveying platform passes through the gantry frame, and the ring cutter mechanism is slidably mounted on the gantry frame. The ring cutter mechanism includes a ring cutter, rotating wheels, a torsion cutter mechanism, and a sliding mechanism. The sliding mechanism includes an upper sliding mechanism and a lower sliding mechanism. Four rotating wheels are designed. A rotating wheel is mounted on each end of the upper sliding mechanism's slide plate via a fixed plate, and a rotating wheel is mounted on each end of the lower sliding mechanism's slide plate via a fixed plate. The upper and lower sliding mechanisms are synchronously driven by the same motor. Torsion cutter mechanisms are mounted on the left and right fixed plates of both the upper and lower sliding mechanisms. A drive motor is mounted on the right fixed plate of the lower sliding mechanism, driving the rotating wheels connected to the right fixed plate of the lower sliding mechanism. The ring cutter is wound around the four rotating wheels and passes through the torsion cutter mechanism. The ring cutter is a double-edged ring cutter.

[0006] The portal frame includes an upper frame, a lower frame, a left frame, and a right frame. The left and right ends of the upper frame are connected to the upper ends of the left and right frames, respectively. The left and right ends of the lower frame are connected to the lower ends of the left and right frames, respectively. The lower end of the lower frame is installed on the ground.

[0007] The aforementioned upper sliding mechanism includes a sliding plate, a slider, a motor, a belt, and a slide rail. A slide rail is installed at the top and bottom of the front of the upper frame of the portal frame. A fixed plate is installed on each of the outer sides of the sliding plate, and a wheel is installed on the fixed plate. A slider is installed at the top and bottom of the fixed plate, and the slider is slidably mounted on the slide rail. The two ends of the belt are respectively installed on the inner ends of the sliding plate. A motor is installed at the rear of the upper frame near the middle. A pulley is installed on the front shaft of the motor. The belt passes around the outside of the pulley, and a reversing wheel is designed on each of the two front sides of the pulley. The reversing wheels are installed on the upper frame, and the two reversing wheels are supported on the outside of the belt.

[0008] The sliding mechanism includes a sliding plate, a slider, a motor, a belt, and a slide rail. A slide rail is installed at the top and bottom of the front of the lower frame of the portal frame. A fixed plate is installed on each of the outer sides of the sliding plate, with a rotating wheel mounted on each plate. A slider is installed at the top and bottom of each fixed plate, and the sliders slide on the slide rails. A belt is installed at both ends corresponding to the inner ends of the sliding plate. A pulley is installed near the center of the rear of the lower frame via a rotating shaft. The rotating shaft on the lower frame is connected to the motor shaft of the upper frame via a connecting shaft. A belt passes around the outside of the pulley, and a reversing wheel is designed on each of the two front sides of the pulley. The reversing wheels are mounted on the lower frame, and the two reversing wheels are supported on the outside of the belt.

[0009] The aforementioned twisting mechanism includes a housing, a twisting shaft, a left cylinder, a right cylinder, a gear, and a clamping mechanism. The twisting shaft is rotatably mounted in the middle of the housing, and the clamping mechanism is mounted at the front end of the twisting shaft. The clamping mechanism is located on the outer side of the front end of the housing. The gear is fixedly mounted in the middle of the twisting shaft. The upper and lower ends of the twisting shaft are respectively mounted inside the upper and lower ends of the housing through bushings. The left and right cylinders are mounted side by side on the outer side of the housing. The front ends of the left and right cylinders are mounted with chucks. A belt is wound around the outside of the gear, and the two ends of the belt are respectively mounted in the chucks of the left and right cylinders. The twisting shaft, the gear, and the housing have axially formed cutting grooves on the same side. The ring cutter passes through the cutting grooves of the housing and the gear and finally ends up in the cutting groove of the twisting shaft. The ring cutter also passes through the clamping mechanism.

[0010] Several small bearings are installed at both ends of the bushing, and the circumferential surface of each small bearing is in tangential contact with the outer circumference of the wrench shaft.

[0011] The lower torsion knife mechanism is equipped with a knife slot bracket on its outer side. The knife slot bracket is plate-shaped with a U-shaped groove at its lower end. The knife slot bracket is secured to both sides of the upper end of the torsion knife mechanism via the U-shaped groove, and both ends of the U-shaped groove are fixed to the two sides of the torsion knife mechanism's housing. A circular hole is located in the center of the upper end of the knife slot bracket, and a knife groove is formed on one side of the hole. The ring knife passes through the knife groove and is located within the circular hole. The conveying platform includes a front conveying platform and a rear conveying platform, forming a knife slot between them for the ring knife to travel through. The upper end of the knife slot bracket is located within the knife slot, and its upper surface is flush with the upper surface of the conveying platform. The front and rear conveying platforms are two independently driven conveying platforms, each driven by a separate motor. The conveying platform is designed to be 70cm above the ground.

[0012] The advantages of this invention are: the ring cutter is designed as a double-edged ring cutter, which only requires a 90-degree twist to change direction when cutting and trimming rectangular sponges, reducing the twisting of the cutter and extending its service life; the four upper and lower rotating wheels move synchronously, resulting in high cutting accuracy; the blade slit support design further ensures cutting accuracy, especially for cutting extra-soft sponges, as the blade slit support can prevent sponge displacement at the cutting point. The conveyor platform is designed with a lower height and smaller overall volume, and its height is exactly the same as the feeding and discharging platforms, facilitating the formation of a production line; the front and rear conveyor platforms of the conveyor platform are driven and controlled by separate motors, facilitating the separation and conveying of the cut sponges first. The twisting blade mechanism uses a cylinder to control the rotation of the twisting blade, which is simple and convenient. Attached Figure Description

A slide rail 77 is installed at the upper and lower positions of the front of the upper frame 21 of the portal frame. A fixed plate 72 is installed on each of the outer sides of the slide plate 71. A rotating wheel 5 is installed on the fixed plate 72. A slider 73 is installed at the upper and lower ends of the fixed plate 72. The slider 73 is slidably installed on the slide rail 77.

[0028] like Figure 8-11 The aforementioned torsion mechanism 6 includes a housing 61, a torsion shaft 62, a left cylinder 63, a right cylinder 64, a gear 65, and a clamping mechanism 8. The torsion shaft 62 is rotatably mounted in the middle of the housing 61. The clamping mechanism 8 is mounted at the front end of the torsion shaft 62 and is located on the outer side of the front end of the housing 61. The gear 65 is fixedly mounted in the middle of the torsion shaft 62. The upper and lower ends of the torsion shaft 62 are respectively mounted inside the upper and lower ends of the housing 61 via bushings. The left cylinder 63 and the right cylinder... The gears 64 and 65 are mounted side-by-side on the outside of the housing 61. Chucks 66 are mounted at the front ends of the left cylinder 63 and right cylinder 64. A belt 67 is wound around the outside of the gear 65, with both ends of the belt 67 installed in the chucks 66 of the left and right cylinders, respectively. A cutting groove 68 is axially formed on the same side of the twisting shaft 62, the gear 65, and the housing 61. The ring cutter passes through the cutting grooves 68 of the housing 61 and the gear 65, and finally resides in the cutting groove of the twisting shaft 62. The ring cutter also passes through the clamping mechanism 8. The twisting mechanism 6 is designed above the upper sliding mechanism, eliminating the need for a cutting groove support. The twisting shaft is a hollow shaft.

[0029] Several small bearings 69 are installed at both ends of the bushing, and the circumferential surface of each small bearing 69 is in tangential contact with the outer circumference of the wrench shaft 62.

[0030] The clamping mechanism 8 is prior art and will not be described in detail in this invention. For example, patent CN201822210593.0 describes the clamping mechanism in detail.

[0031] The lower torsion knife mechanism 6 is equipped with a knife slot bracket 9 on its outer side. The knife slot bracket 9 is plate-shaped, with a U-shaped groove 91 at its lower end. The knife slot bracket 9 is engaged with the upper sides of the torsion knife mechanism 6 through the U-shaped groove 91, and the two ends of the U-shaped groove 91 are respectively fixed to the two sides of the housing of the torsion knife mechanism 6. A circular hole 92 is opened in the middle of the upper end of the knife slot bracket 9, and a knife groove 93 is opened on one side of the circular hole 92. The ring knife 4 passes through the knife groove 93 and is located in the circular hole 92. The conveying platform 1 includes a front conveying platform 11 and a rear conveying platform 12, forming a knife slot for the ring knife 4 to travel between the front conveying platform 11 and the rear conveying platform 12. The upper end of the knife slot bracket 9 is located in the knife slot, and the upper end surface of the knife slot bracket 9 is flush with the upper end surface of the conveying platform 1. The front conveying platform 11 and the rear conveying platform 12 are two independently driven conveying platforms, each driven by a separate motor. The conveying platform 1 is designed to be 70cm above the ground. The cutter slot support 9 operates synchronously with the torsion cutter mechanism, ensuring that the ring cutter is inside the circular hole of the cutter slot support and that the ring cutter does not contact the circular hole.

[0032] In use, this invention cuts or trims rectangular sponges by simply having the sliding mechanism synchronously drive four rotating wheels to the cutting position. One of the rotating wheels rotates via a motor, causing the entire ring cutter to rotate. The upper and lower torsion cutter mechanisms control the ring cutter to twist 90 degrees for reversal by extending one cylinder while the other retracts, or by reversing their movements. When the ring cutter mechanism is not in operation, it can be located inside the right frame of the portal frame. The width of the right frame is 5-30 cm larger than the width of the ring cutter, and the width of the ring cutter is 5-30 cm larger than the width of the conveyor platform.

[0033] The advantages of this invention are as follows: Previously, the ring cutter used a single-edged blade. After cutting, if a reverse cut was needed, a twisting mechanism was required to rotate the ring cutter 180 degrees to complete the cutting operation. This invention uses a double-edged ring cutter, so only the other blade is needed for cutting, eliminating the need for twisting. For cutting and trimming rectangular sponges, this invention only requires a 90-degree twist to meet the cutting needs of rectangular sponges, reducing tool distortion and extending tool life. The four rotating wheels move synchronously, resulting in high cutting precision. Previously, when cutting sponges, a slit was left between the conveyor platforms for the ring cutter to move through. Especially when cutting some extra-soft sponges, the rotation of the ring cutter would pull the extra-soft sponge into the slit, leading to insufficient cutting precision. This invention designs a slit support to further ensure cutting precision. Especially for cutting extra-soft sponges, the slit support is positioned on both sides of the ring cutter and moves synchronously with it. During cutting, the extra-soft sponge is less likely to enter the gap between the conveyor platforms, and the slit support prevents sponge displacement at the cutting point. Traditionally, due to the large angle of the torsion blade, the required deformation height of the blade in conveyor platforms needs to be increased to prevent breakage and facilitate twisting. This necessitates a taller conveyor platform to accommodate the deformation height, resulting in a larger overall cutting equipment, increased size, and higher costs. It also causes inconvenience in later transportation and installation. This invention, with a maximum torsion blade angle of only 90 degrees, allows for a lower conveyor platform height, resulting in a smaller overall equipment size. The height of the conveyor platform is perfectly aligned with the feeding and discharging platforms, facilitating production line integration and simplifying transportation and installation. The front and rear conveyor platforms are driven by separate motors, facilitating the separation and conveying of cut sponges. The torsion blade mechanism uses a cylinder to control the rotation of the blade, which is simple and convenient.
