Description

Technical Field

[0001] This utility model relates to a bag fabric cutting device, belonging to the technical field of cutting and processing equipment. Background Technology

[0002] In the manufacturing process of bags and luggage, fabric cutting is a crucial step that directly affects the quality and production efficiency. Traditional cutting methods rely heavily on manual operation, which is not only inefficient but also prone to errors and material waste due to low cutting accuracy. A search revealed a Chinese patent, CN214033111U, which discloses a cutting device for bag and luggage production. In this patent, the fabric is placed on a conveyor belt on an operating table. The conveyor belt is activated to transport the fabric to the cutting position. A telescopic cylinder is operated to lower the cutting blade, which then contacts and cuts the fabric. During the cutting process, rotating rods A and B, via a disc gear and belt drive, fix the fabric to be cut. After cutting, the telescopic cylinder resets, raising the cutting blade, while the conveyor belt continues to operate, removing the cut fabric from the cutting area. However, the cutting blade of this patent is fixed and cannot be adjusted, making it impossible to cut bag fabrics of different specifications. Furthermore, the bag fabric is fixed to a certain extent during the cutting process, and the bag fabric will undergo slight deformation under the pressure of both the blade and the fixing point, affecting the production quality.

[0037] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0038] like Figure 1-5 As shown, a bag fabric cutting device includes:

[0039] Rack 1;

[0040] The cutting component includes a cutting base 21, a cutting bracket 22 and three cutting blades 23. The cutting base 21 is mounted on the frame 1, and the cutting bracket 22 is slidably mounted on the cutting base 21. The cutting bracket 22 is provided with multiple mounting slots 221, and the cutting blades 23 are mounted in the mounting slots 221.

[0041] The cutting bracket 22 is also provided with three blade spacing adjustment components, which correspond to the mounting groove 221. Each blade spacing adjustment component includes an adjustment bracket 241, an adjustment cylinder 242, and an adjustment connecting roller 243. The adjustment bracket 241 is mounted on the cutting bracket 22, the adjustment connecting roller 243 is mounted on the adjustment bracket 241, the cutting blade 23 is slidably mounted on the adjustment connecting roller 243, and the adjustment cylinder 242 is mounted on the adjustment bracket 241. The movable end of the adjustment cylinder 242 is connected to the cutting blade 23. The adjustment cylinder 242 is adapted to drive the cutting blade 23 to move axially along the adjustment connecting roller 243 to adjust the spacing between two adjacent cutting blades 23.

[0042] A cutting channel 25 is provided between the cutting blade 23 and the frame 1. The bag fabric is suitable for being pulled through the cutting channel 25 by an external traction machine, so as to be cut by the three cutting blades 23.

[0043] In this embodiment, the adjusting connecting roller 243 is provided with a scale.

[0044] Specifically, such as Figure 1-2 As shown, a bag fabric cutting device also includes an auxiliary table 3, which is mounted on the frame 1 and positioned below the cutting blade 23.

[0045] Specifically, the auxiliary platform 3 is provided with evenly distributed negative pressure suction holes, and the auxiliary platform 3 is provided with a suction chamber, with the negative pressure suction holes connected to the suction chamber.

[0046] An air pump 31 is installed on the frame 1. The air inlet of the air pump 31 is connected to the air suction chamber. The air pump 31 is suitable for adsorbing the bag fabric onto the auxiliary table 3 through the negative pressure air suction hole. The air pump 31 is an adjustable pressure regulating air pump 31.

[0047] In this embodiment, when the device starts working, the air pump 31 starts to draw air into the suction chamber in the auxiliary platform 3. Since the negative pressure suction hole is connected to the suction chamber, when the bag fabric is pulled through the auxiliary platform 3, the bag fabric will be attracted to the auxiliary platform by the negative pressure generated by the suction hole. This can ensure that the fabric remains flat and stable during the cutting process and reduce the cutting error caused by the movement of the fabric. After the cutting is completed, since the auxiliary platform 3 has a slope in the direction of the external traction device, the bag fabric will move down the slope under the action of the external traction device and the slope, so as to smoothly slide to the external traction device for winding, realizing an efficient and continuous fabric cutting and collection process.

[0048] Since the suction force generated by the air pump 31 is smaller than the traction force of the external traction device, the fabric can be stably adsorbed on the surface of the auxiliary table 3 during the cutting process to ensure cutting accuracy, and can also be smoothly pulled away by the external traction device after cutting. When the external traction device is started, its larger traction force can overcome the weak suction force of the air pump 31, so that the fabric can slide naturally along the slope of the auxiliary table 3, avoiding the fabric from being stretched and deformed or its movement from being obstructed due to excessive suction force.

[0049] Specifically, as shown in 1-5, a bag fabric cutting device further includes a first guide roller assembly. The first guide roller assembly is disposed at the entrance of the cutting channel 25. The first guide roller assembly includes a first guide roller bracket 41, a first upper guide roller 42 and a first lower guide roller 43. The first guide roller bracket 41 is mounted on the frame 1.

[0052] Specifically, such as Figure 1-5As shown, a bag fabric cutting device further includes a second guide roller assembly. The second guide roller assembly includes a second guide roller bracket 51, a second upper guide roller 52, and a second lower guide roller 53.

[0054] The second guide roller assembly also includes a second drive cylinder 55, which is mounted on the second guide roller bracket 51. The movable end of the second drive cylinder 55 is connected to the second bearing seat 56. The second drive cylinder 55 is adapted to drive the second upper guide roller 52 to move up and down to adjust the size of the second guide channel 54.

[0058] In this embodiment, the drive motor drives the main drive wheel 63 to rotate clockwise, and drives the first driven wheel 61 and the second driven wheel 62 to rotate clockwise via the synchronous belt, thereby moving the bag fabric towards the cutting channel 25.

[0066] In this embodiment, the movement of the cutting blade 23 along the axial direction of the adjusting connecting roller 243 is adjusted by the extension and retraction of the cylinder according to the required fabric specifications, thereby adjusting the spacing between adjacent cutting blades 23 to achieve a suitable spacing between them; the bag fabric is placed on the external traction machine, and the bag fabric is fed into the cutting channel 25 of the cutting device by the traction action of the external traction machine; the drive motor controls the synchronous rotation of the first lower guide roller 43 and the second lower guide roller 53, and the bag fabric enters the cutting channel 25 through the second guide channel 54 and the first guide channel 44 in sequence, and is adsorbed on the auxiliary table 3 through the negative pressure suction hole on the auxiliary table 3;
