Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and more specifically, it relates to a knitted trouser shearing device. Background Technology

[0002] Knitted pants typically refer to pants made of knitted fabric. Before sewing knitted pants, in order to make the upper surface of the knitted pants smoother, the knitted fabric is usually trimmed using a shearing device to keep the length of the pile on the knitted fabric consistent.

[0003] Currently, the main shearing equipment for trimming the surface of knitted pants is the shearing machine. In use, the knitted fabric used for knitted pants is usually wound around the roller of the shearing machine, and the spiral circular blade of the shearing machine is set at a specific height to facilitate trimming the pile to a uniform height. Then, the spiral circular blade is driven to rotate and trim the pile on the surface of the knitted fabric, thereby achieving the effect of shearing the knitted fabric.

[0004] For longer, more upright pile, they can naturally come into contact with the rotating blade and are thus successfully cut off in the first shearing process. However, for pile that is curved or flattened, its natural height is lower than the set height of the blade, so it is missed during shearing, which affects the smoothness of the knitted fabric after trimming.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a knitted pants shearing device, which solves the problem that during the shearing process, due to the different states of the pile on the knitted fabric, it is inevitable that some pile will be missed.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a knitted pants shearing device, comprising a device body containing a spiral circular knife and several rollers, an air outlet frame slidably connected to the device body directly below the spiral circular knife, the opening of the air outlet frame facing the spiral circular knife, a driving component for driving the air outlet frame to move up and down along the inside of the device body, an air pump fixedly connected to the bottom of the device body, a corrugated pipe fixedly connected to the output end of the air pump, the corrugated pipe passing through the air outlet frame and fixedly connected to the air outlet frame, and a collection component for collecting the sheared fluff inside the device body.

[0008] The present invention is further configured such that: the driving component includes a slide rail fixedly connected inside the device body, a movable plate slidably connected on the slide rail, the air outlet frame and the movable plate are fixedly connected, an electric push rod is fixedly connected to the bottom of the device body, and the output end of the electric push rod is fixedly connected to the bottom of the movable plate.

[0009] The present invention is further configured such that: the collection component includes an air suction pipe located inside the device body, one end of the air suction pipe is located between the air outlet frame and the spiral circular knife, and the other end of the air suction pipe passes through the device body to the outside and is fixedly connected to the device body; a fan with its input end facing the air suction pipe is installed at the external end of the air suction pipe, and a collection bag is detachably connected to the output end of the fan.

[0010] The present invention is further configured such that: a fixing ring is fixedly connected to the output end of the fan, the collection bag is sleeved on the fixing ring, and the fixing ring and the collection bag are connected by a clamp.

[0011] The present invention is further configured such that: one end of the suction pipe located inside the device body is fixedly connected to a suction frame to increase the suction range of the suction pipe.

[0012] The present invention is further configured such that: a protective cover is fixedly connected inside the device body, and one side of the protective cover is in contact with the air intake frame.

[0013] The present invention is further configured such that: a number of brush bristles are fixedly connected to the side of the protective cover away from the air intake frame, and the bottom of the brush bristles is in contact with the roller.

[0024] A type of knitted trouser shearing equipment, such as Figures 1-4 As shown, the device body 17 includes a spiral circular cutter 1 and several rollers 2 inside. An air outlet frame 3 is slidably connected to the device body 17 directly below the spiral circular cutter 1. The opening of the air outlet frame 3 faces the spiral circular cutter 1. The device body 17 is provided with a drive component for driving the air outlet frame 3 to move up and down along the inside of the device body 17. An air pump 4 is fixedly connected to the bottom of the device body 17. A bellows 5 is fixedly connected to the output end of the air pump 4. The bellows 5 passes through the air outlet frame 3 and is fixedly connected to the air outlet frame 3. By using the setting of the bellows 5, it can deform with the air outlet frame 3 when it moves, so that the air blown out by the output end of the air pump 4 can be smoothly delivered into the air outlet frame 3. The device body 17 is provided with a collection component for collecting the trimmed fluff.

[0025] When trimming the knitted fabric used for knitted pants, the knitted fabric is interlaced and wound around each roller 2, while the knitted fabric and the opening at the top of the air outlet frame 3 come into contact with each other. Then, the drive component drives the air outlet frame 3 to move upward, and drives the knitted fabric to move in the same direction. When the knitted fabric is adjusted to the appropriate position, the air pump 4 is started. The air pump 4 draws in outside air and converts it into high-pressure air, which is then fed into the bellows 5. The bellows 5 delivers the high-pressure air to the air outlet frame 3. Since the knitted fabric is woven, there are many gaps on the surface. At the same time, the high-pressure air can be sprayed out towards the spiral circular knife 1 through these gaps. At this time, the pile on the knitted fabric, which is in a bent or flat state, will be affected by the wind force and keep it in a vertical state. Then, the equipment body 17 drives the spiral circular knife 1 to rotate, and the spiral circular knife 1 trims the pile on the knitted fabric. At the same time, the collecting component can collect the trimmed pile in time, and the trimmed knitted fabric is conveyed outward by the roller 2, thus completing the effect of trimming the knitted fabric used for knitted pants.

[0026] By using the air pump 4 and the air outlet frame 3, the pile that is bent or flat can be blown up and kept upright, so that the spiral circular knife 1 can smoothly trim this part of the pile and improve the flatness of the knitted fabric after trimming.

[0027] like Figures 1-4 As shown, the drive assembly includes a slide rail 6 fixedly connected inside the device body 17, and a movable plate 7 slidably connected on the slide rail 6, which can improve the stability of the movable plate 7 when moving. The air outlet frame 3 and the movable plate 7 are fixedly connected. An electric push rod 8 is fixedly connected to the bottom of the device body 17. The output end of the electric push rod 8 is fixedly connected to the bottom of the movable plate 7. When the air outlet frame 3 is driven to move upward, the electric push rod 8 is activated, and the movable plate 7 is driven to move upward through the output end of the electric push rod 8. At the same time, the movable plate 7 drives the air outlet frame 3 to move in the same direction, thereby achieving the effect of driving the air outlet frame 3 to move upward.

[0028] like Figures 1-4As shown, the collection assembly includes an air intake pipe 9 located inside the device body 17. One end of the air intake pipe 9 is located between the air outlet frame 3 and the spiral circular knife 1, and the other end of the air intake pipe 9 passes through the device body 17 to the outside and is fixedly connected to the device body 17. A fan 10 with its input end facing the air intake pipe 9 is installed at the external end of the air intake pipe 9. A collection bag 11 is detachably connected to the output end of the fan 10. A fixing ring 12 is fixedly connected to the output end of the fan 10. The collection bag 11 is fitted onto the fixing ring 12. The fixing ring 12 and the collection bag 11 are connected by a clamp 13. The clamp 13 facilitates the disassembly and installation of the collection bag 11 and the fixing ring 12, making it convenient for operators to operate. An air intake frame 14 is fixedly connected to one end of the air intake pipe 9 inside the device body 17 to increase the air intake range of the air intake pipe 9.

[0029] When the spiral circular knife 1 trims the fluff on the knitted fabric, the fan 10 is started. The input end of the fan 10 can generate suction at one end of the suction pipe 9. The trimmed fluff can be sucked into the suction pipe 9 and transported to the collection bag 11 through the suction pipe 9, thereby completing the effect of collecting the trimmed fluff.

[0030] Furthermore, a protective cover 15 is fixedly connected inside the equipment body 17. One side of the protective cover 15 is in contact with the suction frame 14, which can limit the range of motion of the trimmed fluff and further facilitate the collection of the trimmed fluff. Several bristles 16 are fixedly connected to the side of the protective cover 15 away from the suction frame 14. The bottom of the bristles 16 is in contact with the roller 2, which can prevent the fluff from floating outward through the gap between the protective cover 15 and the roller 2.

[0031] The working process of this utility model is as follows:

[0032] When trimming the knitted fabric used for knitted pants, the knitted fabric is interlaced and wound onto each roller 2, while simultaneously bringing the knitted fabric into contact with the opening at the top of the air outlet frame 3. Then, the electric push rod 8 is activated, driving the moving plate 7 upwards via its output end. Simultaneously, the moving plate 7 moves the air outlet frame 3 in the same direction. Once the knitted fabric is in the appropriate position, the air pump 4 is activated. The air pump 4 draws in outside air, converts it into high-pressure air, and inputs it into the bellows 5. The bellows 5 then delivers the high-pressure air to the air outlet frame 3. Because the knitted fabric is woven, there are numerous gaps on its surface, allowing the high-pressure air to pass through. The fibers are sprayed through these gaps towards the spiral circular cutter 1. At this time, the fibers on the knitted fabric, which are in a bent or flattened state, will be affected by the wind and kept upright. Then, the spiral circular cutter 1 is driven to rotate by the main body of the equipment 17. The spiral circular cutter 1 trims the fibers on the knitted fabric. At the same time as cutting, the fan 10 is started. The input end of the fan 10 can generate suction at one end of the suction pipe 9. The trimmed fibers can be sucked into the suction pipe 9 and transported to the collection bag 11 through the suction pipe 9. The trimmed knitted fabric is then transported outward by the roller 2, thus completing the trimming effect of the knitted fabric used for knitted pants.

[0033] By using the air pump 4 and the air outlet frame 3, the pile that is bent or flat can be blown up and kept upright, so that the spiral circular knife 1 can smoothly trim this part of the pile and improve the flatness of the knitted fabric after trimming.

[0034] Example of process parameters

[0035] Example 1: For conventional cotton knitted fabrics

[0036] When processing cotton knitted fabric with a weight of 180 g / m², to achieve the ideal blow-up effect without damaging the fabric, the following settings can be made: First, start the electric push rod 8 and adjust the distance between the top opening of the air outlet frame 3 and the lower surface of the knitted fabric to 2-4 mm. Then, start the air pump 4 and set its output air pressure to 5-8 kPa. Under these parameters, the airflow is sufficient to blow the fallen fibers into a vertical position without causing excessive disturbance to the fabric. This, combined with the spiral circular blade 1, achieves efficient and uniform cutting, improving the flatness of the trimmed fabric by approximately 15% compared to existing technologies.

[0037] Example 2: For thicker synthetic fleece fabrics.

[0038] When processing synthetic fleece fabric with a weight of 300 g / m², stronger blowing force is required due to its longer and more tangled pile. The following settings can be used: adjust the distance between the air outlet frame 3 and the lower surface of the fabric to 3-5 mm using the electric push rod 8. Simultaneously, increase the output air pressure of the air pump 4 to 9-12 kPa. This setting ensures that a strong airflow can penetrate the thicker fabric structure, effectively separating and blowing away the pile, solving the problem of difficult-to-trimmed deep pile.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
