Description

Technical Field

[0001] This utility model relates to the field of Oxford cloth waste strip collection, and in particular to a device for collecting waste strips cut from Oxford cloth calendering machines. Background Technology

[0002] When the calendering unit for Oxford cloth processing is in operation, the Oxford cloth is first unwound by the unwinding mechanism. After being preheated by the heating mechanism, the cloth enters the calendering mechanism. In the calendering mechanism, the Oxford cloth is squeezed and stretched by the calendering rollers. At the same time, the heating softens the cloth material, making it easier to deform according to the shape and pressure requirements of the calendering rollers, thereby achieving the purpose of adjusting the thickness, density, and improving surface smoothness. A cutting blade is installed at the exit of the calender. The cutting blade cuts the edges of the formed sheet-like product. The excess part is called waste strip, which needs to be collected by the operator.

[0003] The utility model patent with announcement number CN220094772U discloses an automated collection device for waste strips from an outdoor tent fabric calendering machine. The device includes a frame, a collection bag, and a blowing device. The collection bag is detachably connected to the frame, and the blowing device blows air towards the opening of the collection bag, allowing the waste strips to enter the collection bag from the opening.

[0004] The aforementioned technical solutions have the following drawbacks: the capacity of the collection bag is limited. When replacing the collection bag, if the calender continues to run, cutting waste strips will always be generated. These waste strips will continuously come out, causing obstacles to the replacement of the collection bag. For example, they may pile up on the ground, and the operator has to pick them up and put them into the new collection bag. At the same time, since the cutting waste strips are continuous, the operator also needs to use a knife to cut the waste strips before replacing the collection bag, making the entire process of replacing the collection bag quite troublesome. Utility Model Content

[0005] To facilitate the replacement of waste strip collection bags, this application provides a waste strip collection device for the trimming of Oxford cloth calendering machines.

[0006] The technical solution of the Oxford cloth calendering machine edge trimming waste strip collection device provided in this application is as follows:

[0007] A device for collecting waste strips from an Oxford cloth calendering machine includes a frame, a collection bag, and a blowing device. The blowing device includes a guide frame, a fan, an air duct, and a cutting block. The air duct is mounted on the frame, with one end connected to the air outlet of the fan and the other end extending into the collection bag. An inlet communicating with the outside is provided on the inner wall of the air duct, and the waste strips pass through the air duct from the inlet and then into the collection bag.

[0008] The cutting blocking component is installed on the air guide pipe. The cutting blocking component is used to block the air guide pipe to prevent the waste strip from passing through when the collection bag is replaced, and to assist the waste strip in cutting. The guide frame is installed on the outer wall of the air guide pipe on the side where the inlet is located. The guide frame is connected to the inlet and is set in a flared shape. The guide frame is used to guide the waste strip and receive the waste strip.

[0009] By adopting the above technical solution, the guide frame is set in a flared shape, which can effectively guide the waste strips to accurately enter the air duct. When the cutting obstruction blocks the air duct and cuts the waste strips, it catches the waste strips that fail to enter the collection bag in time, preventing the waste strips from scattering. After the collection bag is replaced, the cutting obstruction no longer blocks the air duct, and the waste strips continue to enter the collection bag under the action of the air. This effectively reduces the obstruction of the waste strips to the collection bag replacement operation, making the replacement of the collection bag more convenient and faster, and improving work efficiency.

[0010] Preferably, the cutting blocking component includes a drive component, a partition plate, and a cutter. The air duct has a sliding groove for the partition plate to slide. The drive component is disposed on the air duct and is used to drive the partition plate to slide on the sliding groove. The partition plate has a ventilation hole. The end of the partition plate facing the inside of the air duct is the mounting end. The cutter is fixedly disposed on the mounting end and is used to cut the waste strip.

[0011] By adopting the above technical solution, when the collection bag needs to be replaced, the drive unit drives the partition to slide on the slide groove, so that the partition blocks the air duct. At this time, the cutter cuts the waste strip, effectively cutting the waste strip, which facilitates the replacement of the collection bag. In addition, the ventilation holes opened on the partition can ensure the air circulation in the air duct to a certain extent, so that the wind force continues to guide the waste strip, ensuring the stability and reliability of the waste strip collection device.

[0012] Preferably, the cutting blocking component further includes a pad, which is fixedly mounted on the mounting end. The pad is located on the side of the cutter away from the air duct outlet. When the pad presses against the waste strip, there is a gap of less than 1 mm between the cutter and the inner wall of the air duct.

[0013] By adopting the above technical solution, the pad first presses the waste strip, which helps to straighten the waste strip for cutting. At this time, there is a gap of less than 1mm between the cutter and the inner wall of the air duct, which can avoid the cutter from directly contacting the inner wall of the air duct and causing wear. When the operator changes the collection bag, he can manually pull the waste strip to make the waste strip contact the cutter for cutting. This can not only ensure that the cutter cuts the waste strip, but also extend the service life of the cutter and the air duct.

[0014] Preferably, the pad is made of a deformable material, and the side of the pad that presses against the waste strip has anti-slip texture.

[0015] By adopting the above technical solution, the pad is made of deformable material, which allows it to better fit the waste strip and enhance the pressing effect on the waste strip; the anti-slip texture on the side further increases the friction between the pad and the waste strip, preventing the waste strip from sliding during the cutting process, thereby ensuring that the cutter can accurately and efficiently cut the waste strip, improving the success rate and quality of the cutting.

[0016] Preferably, the driving component includes a cylinder and a connecting plate. The partition is fixed to the connecting plate with screws, the cylinder is fixedly disposed on the outside of the air guide pipe, and the piston rod of the cylinder is fixed to the connecting plate with screws.

[0017] By adopting the above technical solution, the cylinder, as the driving component, has the advantages of simple structure, rapid action, and easy control. It can quickly and stably drive the baffle to slide on the slide groove, thereby achieving the isolation of the air duct and the cutting of the waste strip. The baffle and connecting plate, the piston rod of the cylinder and the connecting plate are fixedly connected by screws, which facilitates disassembly and installation, and makes it convenient to repair and replace the cutting blocking component in the later stage, thus improving the maintainability of the device.

[0018] Preferably, the opening of the collection bag is tied to the outlet of the air duct with a rope, and a limiting ring is fixedly fitted at the outlet of the air duct to prevent the rope from moving out of the air duct.

[0019] By adopting the above technical solution, the bag opening is tied to the outlet of the air duct with a rope. The connection method is simple and firm, which facilitates the installation and disassembly of the collection bag. The setting of the limiting ring can effectively prevent the rope from moving out of the air duct, reduce the chance of the collection bag falling off during use, ensure that the waste strips can be accurately collected into the collection bag, and improve the reliability and stability of waste strip collection.

[0020] The main technical effects of this utility model are reflected in the following aspects:

[0021] 1. By setting a cutting and blocking component, this utility model can effectively cut and block the waste strips, effectively reducing the obstruction of the waste strips on the replacement of the collection bag, making the replacement of the collection bag more convenient and quick, and improving work efficiency.

[0022] 2. This utility model incorporates a pad that first presses down on the waste strip, helping to straighten it for cutting. At this point, there is a gap of less than 1mm between the cutter and the inner wall of the air duct, preventing direct contact between the cutter and the inner wall of the air duct and causing wear. When the operator changes the collection bag, they can manually pull the waste strip to make it contact the cutter for cutting. This ensures that the cutter cuts the waste strip and extends the service life of the cutter and the air duct. Attached Figure Description

[0028] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0029] This application discloses a device for collecting waste strips from the trimming of Oxford cloth calenders.

[0030] Reference Figures 1-4 This embodiment of an Oxford cloth calender edge trimming waste strip collection device includes a frame 1, a collection bag 2, and a blowing device 3. The blowing device 3 includes a guide frame 31, a fan 34, an air duct 35, and a cutting blocking component 4. The air duct 35 is mounted on the frame 1. One end of the air duct 35 is connected to the air outlet of the fan 34, and the other end of the air duct 35 extends into the collection bag 2. An inlet communicating with the outside is opened on the inner wall of the air duct 35. The waste strip passes through the air duct 35 from the inlet and then enters the collection bag 2.

[0031] Reference Figures 1-4 The cutting blocking component 4 is installed on the air duct 35. The cutting blocking component 4 is used to block the air duct 35 to prevent the waste strip from passing through when the collection bag 2 is replaced, and to assist the waste strip in cutting. The guide frame 31 is installed on the outer wall of the air duct 35 on the side of the inlet. The guide frame 31 is connected to the inlet and is set in a flared shape. The guide frame 31 is used to guide the waste strip and receive the waste strip.

[0032] Reference Figures 1-4The guide frame 31 is flared out, which can effectively guide the waste strips to accurately enter the air duct 35. When the cutting blocking part 4 blocks the air duct 35 and cuts the waste strips, it receives the waste strips that fail to enter the collection bag 2 in time, preventing the waste strips from scattering. After the collection bag 2 is replaced, the cutting blocking part 4 no longer blocks the air duct 35, and the waste strips continue to enter the collection bag 2 under the action of the wind. This effectively reduces the obstruction of the waste strips to the replacement of the collection bag 2, making the replacement of the collection bag 2 more convenient and faster, and improving work efficiency.

[0033] Reference Figures 1-4 The cutting blocking component 4 includes a drive component 1, a partition plate 43, and a cutter 44. A groove 351 for sliding the partition plate 43 is provided on the air duct 35. The drive component 1 is provided on the air duct 35 and is used to drive the partition plate 43 to slide on the groove 351. A vent hole 431 is provided on the partition plate 43. The end of the partition plate 43 facing the inside of the air duct 35 is the mounting end. The cutter 44 is fixedly provided on the mounting end and is used to cut the waste strip.

[0034] Reference Figures 1-4 When the collection bag 2 needs to be replaced, the drive unit drives the partition 43 to slide on the slide groove 351, so that the partition 43 blocks the air duct 35. At this time, the cutter 44 cuts the waste strip, effectively cutting the waste strip, which facilitates the replacement of the collection bag 2. In addition, the ventilation hole 431 opened on the partition 43 can ensure the air circulation in the air duct 35 to a certain extent, so that the wind force continues to guide the waste strip, ensuring the stability and reliability of the waste strip collection device.

[0035] Reference Figures 1-4 The cutting blocking component 4 also includes a pad 45, which is fixedly installed on the mounting end. The pad 45 is located on the side of the cutter 44 away from the outlet of the air duct 35. When the pad 45 presses the waste strip, there is a gap of less than 1mm between the cutter 44 and the inner wall of the air duct 35.

[0036] Reference Figures 1-4 The pad 45 first presses the waste strip, which helps straighten the waste strip for cutting. At this time, there is a gap of less than 1mm between the cutter 44 and the inner wall of the air duct 35, which can prevent the cutter 44 from directly contacting the inner wall of the air duct 35 and causing wear. When the operator replaces the collection bag 2, he can manually pull the waste strip to make the waste strip contact the cutter 44 for cutting. This can not only ensure that the cutter 44 cuts the waste strip, but also extend the service life of the cutter 44 and the air duct 35.

[0037] Reference Figures 1-4 The pad 45 is made of deformable material, and anti-slip texture is provided on the side of the pad 45 that presses the waste strip.

[0038] Reference Figures 1-4The pad 45 is made of a deformable material, such as rubber or silicone, which allows it to better conform to the waste strip and enhance the clamping effect on the waste strip. The anti-slip texture on the side further increases the friction between the pad and the waste strip, preventing the waste strip from sliding during the cutting process. This ensures that the cutter 44 can cut the waste strip accurately and efficiently, improving the success rate and quality of the cut.

[0039] Reference Figures 1-4 The driving component includes a cylinder 41 and a connecting plate 42. The partition plate 43 is fixed to the connecting plate 42 by screws. The cylinder 41 is fixedly installed on the outside of the air duct 35. The piston rod of the cylinder 41 is fixed to the connecting plate 42 by screws.

[0040] Reference Figures 1-4 The cylinder 41, as the driving component, has the advantages of simple structure, rapid action, and easy control. It can quickly and stably drive the partition 43 to slide on the slide groove 351, thereby achieving the isolation of the air guide duct 35 and the cutting of the waste strip. The partition 43 and the connecting plate 42, the piston rod of the cylinder 41 and the connecting plate 42 are fixedly connected by screws, which is convenient for disassembly and installation, and facilitates the maintenance and replacement of the cutting blocking component 4 in the later stage, thus improving the maintainability of the device.

[0041] Reference Figures 1-4 The opening of the collection bag 2 is tied to the outlet of the air duct 35 with a rope. A limiting ring 352 is fixedly fitted at the outlet of the air duct 35 to restrict the rope from moving out of the air duct 35.

[0042] Reference Figures 1-4 The opening of the collection bag 2 is tied to the outlet of the air duct 35 with a rope. The connection method is simple and firm, which facilitates the installation and disassembly of the collection bag 2. The setting of the limiting ring 352 can effectively restrict the rope from moving out of the air duct 35, reduce the chance of the collection bag 2 falling off during use, ensure that the waste strip can be accurately collected into the collection bag 2, and improve the reliability and stability of waste strip collection.

[0043] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
