Description

Technical Field

[0001] This utility model relates to the field of bag production equipment technology, and in particular to a cutting and flattening device for bag fabrics. Background Technology

[0002] Bags and luggage, as a general term for all kinds of bags for carrying items, encompasses a variety of forms such as shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, crossbody bags, waist bags, and various types of rolling suitcases.

[0003] In the manufacturing process of bags, fabric cutting is a crucial step. It involves cutting the fabric into specific shapes and then stitching them together to form the complete bag structure. The precision of fabric cutting directly affects the quality and efficiency of bag production.

[0004] In production practice, stacked bag fabrics often exhibit defects such as curling edges and wrinkles due to material properties and uneven stress. To solve this problem, existing technologies typically employ equipment equipped with pressure rollers, which ensure the fabric remains flat during processing through the rolling action of the rollers.

[0005] However, since the working path of the pressure roller is highly overlapping with that of the cutting mechanism, in order to avoid mutual interference during operation, the pressure roller is usually designed to be rotated to change its position so as to achieve continuous operation.

[0006] In view of this, this study proposes an innovative bag fabric cutting and flattening device, which aims to reduce the labor intensity of operators and improve the efficiency and accuracy of fabric flattening and cutting operations. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention proposes a cutting and flattening device for bag fabrics. This device assists in stretching and flattening the fabric, effectively preventing errors in the processing path and ensuring the fabric does not meet expectations. This device solves the problem of existing technologies relying solely on pressure rollers for operation, requiring multiple rotations, resulting in time-consuming and labor-intensive operations.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A cutting and flattening device for bag fabrics includes a support base, a base material placed on top of the support base, and a cutting mechanism disposed on the upper side of the base material. The device also includes a clamping mechanism and a material transfer mechanism, located on the left and right sides of the cutting mechanism, respectively. The clamping mechanism includes two clamping plates arranged vertically, with the base material positioned between the two clamping plates. The lower clamping plate is fixedly connected to the support base, while the upper clamping plate is slidably connected to the support base. The material transfer mechanism includes a fixed plate and a movable plate. The fixed plate is slidably connected to the support base via a left-right moving component, and the movable plate is slidably connected to the fixed plate via a right-up moving component.

[0010] Preferably, the bearing base is fixedly connected to a vertically oriented positioning shaft on its front and rear sides respectively, and the upper clamping plate is slidably connected to both positioning shafts. Furthermore, a compression spring is sleeved on the outer side of each positioning shaft, and a limiting ring is sleeved on the outer side of each positioning shaft. The two axial ends of the compression spring abut against the corresponding limiting ring and the clamping plate respectively.

[0011] Preferably, each of the limiting rings is provided with a synchronizing element on one side, and the synchronizing element is connected to the fixed plate through a transmission mechanism.

[0012] Preferably, the transmission mechanism includes a plate chain, which is slidably connected to the bearing base, and the lower end of the plate chain is fixedly connected to a synchronizing element. Furthermore, each plate chain is meshed with a driven gear on its upper side, and a rack is fixedly connected to the left and right sides of the fixed plate, with the racks being adapted to and connected to the driven gears.

[0013] Preferably, the clamping plate, the fixed plate, and the movable plate are provided with multiple clearance grooves running vertically through one end near the cutting mechanism, and the clearance grooves on the clamping plate and the fixed plate and the movable plate are arranged alternately.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a material transfer mechanism, a cutting mechanism, and a clamping mechanism arranged sequentially from left to right on the upper part of the support base. In practical applications, the material transfer mechanism drives the left end of the base material to move to the left, thereby adjusting the position of the base material below the cutting mechanism to achieve an automated cutting process. Simultaneously, the clamping mechanism consists of two clamping plates arranged vertically, with the base material precisely positioned between them. To ensure operational stability, the lower clamping plate remains fixed to the support base, while the upper clamping plate is allowed to slide on the support base. This design enables vertical movement of the upper clamping plate, thereby adjusting the distance between the two clamping plates and thus adjusting the clamping force applied to the base material. This design effectively prevents damage to the base material due to excessive friction under the action of the material transfer mechanism, while also preventing the left side of the base material on the right side of the cutting mechanism from losing necessary tension during the cutting process, ensuring the base material maintains appropriate tension.

[0022] 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.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Please refer to Figure 1 A cutting and flattening device for bag fabrics is disclosed, the structure of which is consistent with existing technology devices, including a support base 2. It is worth noting that the support base 2 can actually be understood as a base and a corresponding outer shell and fixing device assembly. For ease of understanding, we define it as support base 2. The device is designed to provide an efficient and precise cutting method to meet the specific needs of bag fabric processing.

[0025] Therefore, base material 1 is placed above the supporting base 2. It should be noted that in practical applications, such as... Figure 1 As shown, there is a slight indentation on the right side of the base material 1. Typically, a constraint roller is installed at this location. Through the contact between the lower end of the constraint roller and the base material 1, the base material 1 is forced to increase its vertical projection length while maintaining a constant horizontal projection length, thus ensuring that the base material 1 is taut. This design ensures that the base material 1 remains stable during the cutting process, avoiding cutting errors caused by fabric slack.

[0026] Accordingly, a cutting mechanism is configured on the upper side of the base material 1. When the base material 1 is taut, both the laser emitter and the rotating cutting wheel can quickly and accurately cut the base material 1. The cutting mechanism is designed to provide high-precision cutting to meet the fine processing requirements of bag fabrics.

[0027] Compared to existing technology, this device is further equipped with a clamping mechanism and a material transfer mechanism 4, which are respectively located on the left and right sides of the cutting mechanism. This design increases the functionality of the device, making the cutting process more automated and efficient.

[0028] For details, please refer to Figure 1 and Figure 4 The clamping mechanism is located on the right side of the cutting mechanism. In practical applications, the clamping mechanism fixes the position of the end of the base material 1, and together with the constraint roller, ensures that the base material 1 remains taut at all times. The clamping mechanism is designed to provide stable fixation of the base material 1 to support continuous cutting operations.

[0029] Further, please refer to Figure 2 and Figure 3The material transfer mechanism 4 is located on the left side of the cutting mechanism. In actual operation, the material transfer mechanism 4 can drive the left end of the base material 1 to move to the left, thereby changing the position of the base material 1 below the cutting mechanism and realizing the automated cutting process of the base material 1. The material transfer mechanism 4 is designed to provide a continuous supply of base material 1 to support high-efficiency cutting operations.

[0030] Specifically, the clamping mechanism consists of two vertically arranged clamping plates 3, with the base material 1 placed between the two clamping plates 3. This design ensures the stability and flatness of the base material 1 during the cutting process.

[0031] Meanwhile, the clamping plate 3, which is positioned lower, is fixedly connected to the bearing base 2, while the clamping plate 3, which is positioned higher, is slidably connected to the bearing base 2. This design allows the clamping mechanism to adapt to base materials 1 of different thicknesses while maintaining a stable clamping effect.

[0032] In actual operation, the material transfer mechanism 4 drives the base material 1 to move continuously to the left until the length of the base material 1 on the left side of the cutting mechanism reaches the expected value. At this point, the cutting mechanism completes the cutting of the base material 1. During the above process, when the material transfer mechanism 4 drives the base material 1 to the left, in order to avoid damage to the base material 1 due to excessive friction between the clamping plate 3 and the base material 1, the device can move the relatively high clamping plate 3 upward, increasing the distance between the two clamping plates 3, thereby reducing the contact area between the clamping plate 3 and the base material 1. Correspondingly, when the cutting mechanism completes or begins cutting, the left end of the base material 1 located on the right side of the cutting mechanism lacks the tension provided by the material transfer mechanism 4. At this time, in order to continuously ensure that the base material 1 is in a taut state and avoid affecting the subsequent cutting process, the device can move the clamping plate 3 downward, reducing the distance between the two clamping plates 3, increasing the contact area between the clamping plate 3 and the base material 1, and ensuring that the base material 1 does not change position.

[0033] It must be pointed out that in actual operation, if the clamping plate 3 remains in continuous contact with the base material 1, and the clamping force applied to the base material 1 is adjusted only in different working modes, then the clamping plate 3 can be used to assist in stretching the base material 1, ensuring that the base material 1 always remains flat and preventing wrinkles from forming. In this case, after the cutting mechanism completes the cutting task, the base material 1 on the left side of the cutting mechanism will naturally sag due to its own gravity, thereby achieving synchronous flattening. This design not only improves the accuracy of cutting but also reduces the need for subsequent flattening operations, thus improving overall production efficiency.

[0034] Therefore, this device has vertically oriented positioning shafts 9 fixedly connected to the front and rear sides of the support base 2. The relatively higher clamping plate 3 is simultaneously slidably connected to these two positioning shafts 9. This design ensures precise position control of the clamping mechanism during the cutting process, thereby improving the cutting quality.

[0035] In addition, a compression spring 8 is fitted on the outer side of each positioning shaft 9. This, combined with the limiting ring 10 fitted on the outer side of the positioning shaft 9, constrains the two axial ends of the compression spring 8 to abut against the corresponding limiting ring 10 and clamping plate 3. This allows the compression spring 8 to ensure that the relatively upper clamping plate 3 always has a downward movement tendency. Simultaneously, this design utilizes the influence of the limiting ring 10 on the upper position of the compression spring 8 to control the downward pressure on the clamping plate 3 by changing the height of the limiting ring 10. This allows for the technical effect of changing the clamping force applied by the clamping plate 3 to the base material 1 in different working modes. This design provides a flexible clamping force adjustment mechanism to adapt to base materials 1 of different materials and thicknesses.

[0036] Specifically, such as Figure 4 , Figure 5 As shown, this device has a corresponding synchronizing element 6 on one side of each limiting ring 10. The height of the synchronizing element 6 directly determines the height of the limiting ring 10. This design makes the height adjustment of the limiting ring 10 simple and precise, thereby ensuring the stability and reliability of the clamping mechanism.

[0037] Furthermore, a transmission mechanism 7 is configured on the upper side of the synchronizing element 6. This transmission mechanism 7 includes a plate chain 702, which is slidably connected to the supporting base 2, and the lower end of the plate chain 702 is firmly connected to the synchronizing element 6. Therefore, by sliding the plate chain 702, the height of the synchronizing element 6 can be controlled, thereby controlling the height of the limiting ring 10. This design provides a precise height adjustment mechanism for the limiting ring 10 to adapt to different cutting requirements.

[0038] Specifically, such as Figure 2 , Figure 3 As shown, the material transfer mechanism 4 consists of a fixed plate 402 and a movable plate 403. The fixed plate 402 is slidably connected to the bearing base 2 via left-right moving components. Figure 2 Combination Figure 4 As can be seen, the left and right moving components can be operated using a lead screw and a drive motor. In practical applications, the left and right moving components can also be cylinders. The specific form needs to be determined based on the site environment, displacement length, and the material of the base material to be cut. This design provides a flexible choice of moving mechanism to adapt to different working conditions and cutting requirements.

[0039] Furthermore, the movable plate 403 and the fixed plate 402 are slidably connected. By adjusting the distance between the movable plate 403 and the fixed plate 402, the left end of the base material 1 can be clamped and fixed, thereby completing the processing. This design ensures the stability and accuracy of the base material 1 during the cutting process.

[0040] like Figure 2 Combination Figure 3As shown, the fixed plate 402 has a U-shaped structure, and a vertically moving member 404 is fixedly connected inside its U-shaped opening. By constraining the fixed connection between the movable end of the vertically moving member 404 and the movable plate 403, a sliding connection between the movable plate 403 and the fixed plate 402 can be achieved. This design provides a flexible position adjustment mechanism for the movable plate 403 to adapt to different cutting requirements.

[0041] Similarly, the vertical moving component 404 used in this device is a cylinder. Like the horizontal moving component, its specific form needs to be determined based on the site environment, displacement length, and the material of the base material 1 to be cut. This design provides flexible selection of moving components to adapt to different working conditions and cutting requirements.

[0042] It is worth noting that the clamping plate 3, the fixed plate 402, and the movable plate 403 all have multiple through-hole clearance slots 5 near the cutting mechanism, and the clearance slots 5 on the clamping plate 3 are staggered with those on the fixed plate 402 and the movable plate 403. This design allows the clamping mechanism and the material transfer mechanism 4 to simultaneously clamp and fix the left end of the base material 1, effectively preventing the left end of the base material 1 from curling and deforming due to lack of fixation, thereby ensuring the normal operation of the material transfer mechanism 4. This design improves the stability and reliability of the device and ensures the smooth progress of the cutting process.

[0043] Furthermore, a driven gear 701 is meshed and driven to the upper side of each plate chain 702. Simultaneously, a rack 401 is fixedly connected to each of the left and right sides of the fixed plate 402, and the rack 401 is adapted to the driven gear 701. This design provides a precise transmission mechanism to ensure the synchronous and coordinated movement of the material transfer mechanism 4 and the clamping mechanism.

[0044] Therefore, in practice, during a single cutting process of the base material 1, each driven gear 701 is affected by the rack 401 and undergoes a forward and reverse rotation once. This design ensures the synchronization of movement between the material transfer mechanism 4 and the clamping mechanism, improving the accuracy and efficiency of the cutting process.

[0045] according to Figure 4 and Figure 5 The plate chain 702 structure shown in this utility model, in actual operation,

[0046] First, the material transfer mechanism 4 drives the base material 1 to move to the left. At this time, the driven gear 701 on the right side is driven by the rack 401 to lower the limiting ring 10, which shortens the distance between the two clamping plates 3. Thus, the clamping plates 3 can fully smooth the wrinkles on the surface of the base material 1 and ensure the flatness of the base material 1.

[0047] Subsequently, as the material transfer mechanism 4 continues to move to the left, the rack 401 meshes with the driven gear 701 on the left. The driven gear 701 on the left rotates and drives the limiting ring 10 to descend further. At this time, the distance between the two clamping plates 3 is shortened again, and the clamping plates 3 completely fix the base material 1. During this process, the stretching effect of the material transfer mechanism 4 on the base material 1 further ensures the flatness of the base material 1, and the fully taut base material 1 greatly facilitates the cutting process.

[0048] Next, when the material transfer mechanism 4 moves to the predetermined position, the material transfer mechanism 4 stops, and the cutting mechanism begins to cut the base material 1. After the cutting is completed, the up and down moving component 404 causes the movable plate 403 to rise, and the base material 1 falls naturally and is stacked and stored inside the bearing base 2.

[0049] Afterwards, the moving mechanism moves in the opposite direction and moves to the right. At this time, the rack 401 drives the driven gear 701 on the left to rotate, the limit ring 10 rises, the clamping plate 3 completely fixes the base material 1, and the base material 1 moves slowly to the right relative to the clamping plate 3. During this process, the distance between the left end of the base material 1 and the left end of the clamping plate 3 gradually decreases.

[0050] Finally, when the moving mechanism moves to the position where the clearance grooves 5 on the movable plate 403, the fixed plate 402, and the clamping plate 3 overlap, the up-and-down moving component 404 causes the movable plate 403 to descend, thus fixing the left end of the base material 1. This design ensures the continuity and efficiency of the entire cutting process while guaranteeing the cutting quality.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
