Description

Technical Field

[0001] This utility model belongs to the technical field of fabric bagging machines, specifically relating to a folding automatic fabric bagging machine. Background Technology

[0002] Currently, some fabrics, after being processed through printing and dyeing, are packaged into thin film bags. Figure 1 Taking printed and dyed fabrics as an example, the process involves manually folding both sides of the fabric towards the center line, stacking the folded fabrics to a certain quantity, and then packing them into a film bag. Since printed and dyed fabrics are typically 1m-2m long and made of soft, lightweight materials, manually pushing the fabrics into the bag is time-consuming and inefficient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a folding automatic fabric bagging machine.

[0005] The first belt conveyor, the second belt conveyor, and the adsorption and fixing mechanism are arranged sequentially along the same straight line. The fabric pressing mechanism is located above the first belt conveyor and is used to press down the folded position of the fabric. The first belt conveyor is used to feed the fabric and transport the pressed fabric to the second belt conveyor. The bag placing mechanism is located beside the adsorption and fixing mechanism and is used to place unused packaging bags. The conveying mechanism is used to transport the packaging bags on the bag placing mechanism to the adsorption and fixing device. The adsorption and fixing device is used to adsorb and fix the bottom of the packaging bags. The bag opening and closing mechanism is located above the end of the adsorption and fixing device near the second belt conveyor and is used to open the bag opening. The second belt conveyor is used to convey the fabric into the packaging bag on the adsorption and fixing device.

The first mounting frame is fixedly mounted, the first driving device is fixedly connected to the first mounting frame, and the fabric pressing component is fixedly connected to the first driving device. Under the action of the first driving device, the fabric pressing component presses down on the folded position of the fabric and away from the first belt conveyor.

[0007] Preferably, the bag placement mechanism includes a bag placement plate, which is fixed to the worktable and is used to place unused packaging bags. Each side of the bag placement plate is provided with at least one positioning block, which is used to position and cooperate with the packaging bag.

[0008] Preferably, the bag placement mechanism further includes a separation component, which includes a connecting seat, a connecting shaft, and a plurality of metal springs. The connecting seat is fixedly connected to the worktable at a position located outside the bag placement plate. The connecting shaft is fixedly connected to the connecting seat. The plurality of metal springs are spaced apart along the length of the connecting shaft. The first end of each metal spring is fixedly connected to the connecting shaft, and the second end of the metal spring extends to the top of the bag placement plate for pressing against the packaging bag on the bag placement plate.

[0009] Preferably, the bag placement mechanism further includes a second driving device, and the bag placement plate is mounted on the second driving device, and the bag placement plate moves up and down under the action of the second driving device.

[0010] Preferably, the separation assembly further includes a bag-separating rod, which is arranged in the same direction as the connecting shaft and located above the metal spring sheet. The bag-separating rod is slidably connected to the worktable in a direction perpendicular to its own length.

[0012] Preferably, the second belt conveyor is provided with a pushing mechanism, which includes a second mounting frame, a third driving device, a pushing component, and a fourth driving device.

[0013] The second mounting bracket is slidably connected to the worktable. The third driving device is used to drive the second mounting bracket to move synchronously and in the opposite direction along the conveying direction of the first belt conveyor. The pushing component includes a limiting plate and a pushing block fixedly connected to the bottom of the limiting plate. The limiting plate can move up and down relative to the second mounting bracket. The bottom surface of the limiting plate has a limiting surface on the side of the pushing block away from the mounting bracket. The limiting surface is horizontally set. The side of the pushing block away from the mounting bracket is a pushing surface. The second driving device is mounted on the mounting bracket and is used to drive the pushing component to move up and down.

[0014] Preferably, the bottom of the push block abuts against the conveyor belt of the first belt conveyor.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] After the fabric is fed onto the first belt conveyor, it is pressed down by the fabric pressing mechanism. This compacts the folds of the fabric, greatly reducing arching at the folds and providing a neat material base for subsequent automatic bagging. Next, the first belt conveyor transports the fabric to the second belt conveyor. Simultaneously, a handling mechanism moves a bag from the bagging mechanism to the suction and fixing device. The suction and fixing device attaches to the bottom of the bag, and the bag opening and closing mechanism opens the bag.

[0038] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] A folding automatic fabric bagging machine, see [link / reference] Figures 2-11 It includes a workbench 100 and a first belt conveyor 200, a fabric pressing mechanism 300, a second belt conveyor 400, a bag placing mechanism 500, a conveying mechanism 600, an adsorption and fixing device 700 and a bag opening and closing mechanism 800, all mounted on the workbench 100.

[0040] The first belt conveyor 200 and the second belt conveyor 400 both use existing belt conveyors to transport the fabric. The adsorption and fixing device 700 uses an existing vacuum adsorption belt conveyor with adsorption holes on the conveyor belt to adsorb the bottom surface of the packaging bag. The first belt conveyor 200, the second belt conveyor 400, and the adsorption and fixing device 700 are arranged sequentially in a straight line, eliminating bends in the conveying process and allowing for direct and smooth fabric transport. The fabric pressing mechanism 300 is located above the first belt conveyor 200 and is used to press down the folded position of the fabric. The first belt conveyor 200 is used for feeding the fabric and transporting the pressed fabric to the second belt conveyor 400. The bag placing mechanism 500 is located beside the adsorption and fixing device 700 and is used to place unused packaging bags. The conveying mechanism 600 is used to transport the packaging bags from the bag placing mechanism 500 to the adsorption and fixing device 700. The adsorption and fixing device 700 is used to adsorb and fix the bottom of the packaging bag. The bag opening and closing mechanism 800 is located above the end of the adsorption and fixing device 700 near the second belt conveyor 400. The bag opening and closing mechanism 800 is used to open the bag opening of the packaging bag. The second belt conveyor 400 is used to convey the fabric into the packaging bag on the adsorption and fixing device 700.

[0041] When it is necessary to bag the fabric, the folded fabric is placed on the first belt conveyor 200 and stacked, or the fabric is placed on the first belt conveyor 200, folded, and stacked. After a certain number are stacked, the fabric is pressed down by the pressing mechanism 300. This presses down the folds of the fabric, greatly reducing the arching phenomenon at the folds and providing a neat material base for subsequent automatic bagging. Then, the first belt conveyor 200 operates, and the fabric is simultaneously conveyed to the second belt conveyor 400. During the pressing / conveying of the fabric, the handling mechanism 600 moves a packaging bag from the bagging mechanism 500 to the suction and fixing device 700. The suction and fixing device 700 suctions and fixes the bottom of the packaging bag, the bag opening and closing mechanism 800 opens the bag opening, and finally, the second belt conveyor 400 conveys the fabric into the packaging bag, completing the bagging of the fabric. This device can complete the bagging and packaging of fabrics, which is faster and more efficient than traditional manual bagging.

[0042] The following describes the pressing mechanism 300, the bag placement mechanism 500, the handling mechanism 600, and the bag opening and closing mechanism 800.

[0043] The fabric pressing mechanism 300 includes a first mounting frame 310, a first driving device 320, and a fabric pressing component 330. The first mounting frame 310 is fixedly mounted on the frame of the first belt conveyor 200. The first driving device 320 can be, for example, a cylinder, which is fixedly connected to the first mounting frame 310. The fabric pressing component 330 is fixedly connected to the output end of the first driving device 320, and moves up and down under the action of the first driving device 320. When it is necessary to press down the folded position of the fabric, the first driving device 320 drives the fabric pressing component 330 to move downward, and the fabric pressing component 330 presses down to compact the folded position of the fabric; after pressing down, the first driving device 320 drives the fabric pressing component 330 to move upward to avoid affecting the feeding and movement of the fabric. In this embodiment, since the fabric is folded by aligning the two long sides with the center line, the folded position, i.e., the crease, is on both sides, the folding component specifically consists of two pressing strips, corresponding to the two creases on both sides of the fabric.

[0044] The bag placement mechanism 500 includes a bag placement plate 510, which is fixed to the worktable 100. The bag placement plate 510 is used to place unused packaging bags (film bags). Each side of the bag placement plate 510 is provided with at least one positioning block 520, which is used to position and cooperate with the packaging bag. After the packaging bag is placed on the bag placement plate 510, it is positioned by the positioning block 520 on each side of the bag placement plate 510, and the packaging bag can be neatly placed on the bag placement plate 510. The bag placement mechanism 500 also includes a separating component 530, which is located on the side of the bag placement plate 510 near the adsorption and fixing device 700, and outside the positioning block 520. The separating component 530 includes a connecting seat 531, a connecting shaft 532, and multiple metal springs 533. The connecting seat 531 is fixedly connected to the workbench 100 at a position outside the bag-holding plate 510. The connecting shaft 532 is horizontally fixedly connected to the connecting seat 531. In this embodiment, since the connecting shaft 532 has a certain length, there are multiple connecting seats 531, and the connecting shaft 532 is supported by multiple connecting seats 531 to ensure its rigidity. The multiple metal springs 533 are spaced apart along the length direction of the connecting shaft 532. The first end of each metal spring 533 is fixedly connected to the connecting shaft 532, and the second end of the metal spring 533 extends to the top of the bag-holding plate 510 for pressing against the packaging bag on the bag-holding plate 510. When the handling mechanism 600 removes the top layer of packaging bag, the edges of the bottom layer of packaging bag are pressed together by the metal spring 533. The bottom layer of packaging bag will not move with the top layer of packaging bag, ensuring that only one top layer packaging bag is taken at a time, avoiding bagging failure caused by incorrect bag supply.

[0045] After a certain number of packaging bags are removed, the metal spring 533 can no longer press down on the packaging bags. Therefore, the bag placement mechanism 500 also includes a second driving device. The bag placement plate 510 is mounted on the second driving device, and the bag placement plate 510 moves up and down under the action of the second driving device. When the number of packaging bags decreases, the second driving device drives the bag placement plate 510 to move upward, so that the top layer of packaging bags is still pressed against the metal spring 533. Since the metal spring 533 is a thin metal sheet with a certain degree of elasticity, the second driving device does not need to be configured with high movement precision. It is only necessary to ensure that the top layer of packaging bags can be pressed down by the metal spring 533, and the metal spring 533 can deform to a certain extent.

[0046] The transmission structure of the second drive device can realize the up and down movement of the bag plate 510 through transmission structures such as gear rack, lead screw nut, and connecting rod, which can be set according to actual needs.

[0047] The separating assembly 530 also includes a bag-separating rod 534, which is arranged in the same direction as the connecting shaft 532, and the two are specifically parallel. Both ends of the bag-separating rod 534 are slidably connected to the worktable 100 via guide rail sliders, and it can slide horizontally in a direction perpendicular to its own length. The height of the bag-separating rod 534 is higher than the metal spring 533, and it is located above the metal spring 533. When the conveying mechanism 600 lifts a packaging bag above the bag-separating rod 534, the bag-separating rod 534 is driven to move horizontally in a direction perpendicular to its own length. This completely separates the packaging bag from the lower packaging bag, preventing the lower packaging bag from moving out with the upper packaging bag due to the adhesion between the two packaging bags. This further ensures that only the topmost packaging bag is taken at a time, avoiding bagging failures caused by incorrect bag supply.

[0048] Both the handling mechanism 600 and the bag opening / closing mechanism 800 use suction cups 810 to adhere the packaging bag. The suction cups 810 can be conventional vacuum suction cups available on the market, and the number of suction cups 810 can be set according to the size of the packaging bag. During handling, the suction cups 810 move downwards to adhere to the packaging bag, then move upwards, then laterally from above the bag placement mechanism 500 to above the suction fixing device 700, then move downwards to place the packaging bag on the suction fixing device 700, and finally move upwards to avoid affecting the packaging. After the packaging bag is placed on the suction fixing device 700, its bottom surface is adhered, and the bag opening / closing mechanism 800 adheres to the top surface of the packaging bag and moves it upwards to open the bag opening. The movement capability of the suction cups 810 in the handling mechanism 600 and the bag opening / closing mechanism 800 can be achieved using existing conventional structures. For example, vertical movement can be achieved through cylinder drive, and movement between the bag placement mechanism 500 and the suction fixing device 700 can be achieved through guide rails. These are all existing conventional structures and will not be elaborated further.

[0049] In this embodiment, the second belt conveyor 400 is equipped with a pushing mechanism 900, which includes a second mounting frame 910, a third driving device 920, a pushing assembly 930, and a fourth driving device 940. A guide rail is provided on the worktable, arranged along the conveying direction of the transmission belt of the first belt conveyor 200. The second mounting frame 910 is slidably connected to the worktable via the guide rail. The third driving device 920 is fixed to the second mounting frame 910 and is used to drive the second mounting frame 910 to move synchronously and in the opposite direction along the conveying direction of the transmission belt of the second belt conveyor. Specifically, a rack is provided on the worktable in the same direction as the guide rail. The third driving device 920 includes a motor 921, a reducer 922, and a gear 923. The reducer 922 is fixed to the second mounting frame 910, and its two ends are respectively connected to the rotating shaft of the motor 921 and the gear 923. The gear 923 engages with the rack. When the motor 921 runs, the second mounting frame 910 slides along the guide rail through the engagement of the gear 923 and the rack. The pushing component 930 includes a limiting plate 931 and a pushing block 932 fixedly connected to the bottom of the limiting plate 931. The limiting plate 931 can move up and down relative to the second mounting frame 910. A limiting surface 9311 is located on the bottom surface of the limiting plate 931, on the side of the pushing block 932 away from the second mounting frame 910. The limiting surface 9311 is horizontally positioned. In this embodiment, the length of the limiting surface 9311 is greater than half the length of the fabric to be packaged; preferably, the length of the limiting surface 9311 is approximately two-thirds of the length of the fabric to be packaged. The pushing block 932 is a strip-shaped block arranged along the width direction of the limiting plate 931, with both ends extending to the two long sides of the limiting plate 931. The side of the pushing block 932 away from the second mounting frame 910 is the pushing surface 9321, and the bottom of the pushing block 932 abuts against the conveyor belt. The fourth driving device 940 is preferably a cylinder, which is mounted and fixed on the second mounting bracket 910 and is used to drive the push component 930 to move up and down, thereby driving the push component 930 to move up and down.

[0050] After the fabric is conveyed onto the second belt conveyor 400, the third drive device 920 and the fourth drive device 940 move the limiting surface 9311 of the limiting plate 931 to contact the top surface of the fabric to be packaged, and move the pushing surface 9321 of the pushing block 932 to contact the end face of the fabric to be packaged. The bottom surface of the pushing block 932 contacts the conveyor belt of the second belt conveyor. Then, under the action of the conveyor belt, the limiting plate 931, and the pushing block 932, the fabric is pushed into the packaging bag. After the fabric is completely pushed into the packaging bag, the third drive device 920 moves to the initial position, and at the same time, the fourth drive device 940 drives the pushing component 930 to move upward to prepare for the next fabric loading. The above-mentioned pushing component 930 has the following beneficial effects:

[0051] (1) The pusher block 932 pushes the fabric at the end of the fabric, which ensures that the fabric has sufficient power to push it into the packaging bag, improving the reliability of the packaging process. The limiting surface 9311 of the limiting plate 931 contacts the top surface of the fabric and limits the top surface of the fabric. When the fabric tends to arch during the process of pushing the fabric into the packaging bag, it will be limited by the limiting surface 9311 of the limiting plate 931, so that the fabric can remain basically flat, avoid arching, and improve the packaging quality.

[0052] (2) The push block 932 abuts against the conveyor belt of the second belt conveyor device. On the one hand, the push block 932 can push the bottommost piece of cloth, preventing the bottommost piece of cloth from being unable to be pushed and getting stuck between the push block 932 and the conveyor belt, ensuring that all pieces of cloth can be pushed into the packaging bag. On the other hand, the push block 932 can provide a stable support for the limiting plate 931, so that the limiting plate 931, especially its free end, can be basically in a horizontal state, avoiding the problem of pressure being applied to the cloth due to the free end of the limiting plate 931 drooping, which would affect the packaging reliability and packaging quality.

[0053] (3) The second mounting bracket 910 moves synchronously with the conveyor belt under the action of the third driving device 920, that is, the push block 932 moves synchronously with the conveyor belt. This helps to ensure the flatness of the fabric and avoid the problem of misalignment, wrinkles and surface wear caused by the two being out of sync. It also avoids the problem of wear caused by the push block 932 sliding relative to the conveyor belt.

[0054] The pushing assembly 930 also includes a connecting plate 933 and reinforcing ribs 934. The connecting plate 933 is slidably connected to the second mounting bracket 910, and the output end of the fourth driving device 940 is connected to the connecting plate 933 to drive the connecting plate 933 to move up and down. There are two reinforcing ribs 934, the first end of each reinforcing rib 934 is fixedly connected to the bottom of the connecting plate 933, and the second end of the reinforcing rib 934 extends along the conveying direction of the conveyor belt. One end of the limiting plate 931 is fixedly connected to the bottom of the connecting plate 933 by the two reinforcing ribs 934.

[0055] In this embodiment, the end of the second belt conveyor is provided with a bag-supporting mechanism, which includes two sets of bag-supporting assemblies 1000. A gantry frame 110 is provided on the workbench, and the two sets of bag-supporting assemblies 1000 are respectively located on both sides of the gantry frame 110. The two sets of bag-supporting assemblies 1000 have the same structure, and one set will be described below.

[0056] The bag-supporting assembly 1000 includes a side U-shaped strip 1010 and a resetting member. The side U-shaped strip 1010 is U-shaped, with one end rotatably connected to the gantry frame 110 via a vertical connecting shaft 1020, and the other end forming the bag-supporting part 1011. The internal height of the side U-shaped strip 1010 (i.e., the distance between the two inner side walls of the U-shape) is not less than the height of the fabric to be packaged, so that after the fabric is output from the second belt conveyor 400, both sides of the fabric can move through the side U-shaped strips 1010 of the two bag-supporting assemblies 1000 to the packaging bag on the packaging table. The resetting member (not shown in the figure) is a spring, with one end fixed to the worktable 100. A connecting block 1030 is fixed to the connecting shaft 1020, and the other end of the resetting member is fixed to the connecting block 1030, thereby pulling the connecting block 1030 to rotate the connecting shaft 1020, causing the side U-shaped strip 1010 to rotate to a closed state. In the closed state, the side U-shaped strips 1010 are arranged along the width direction of the conveyor belt of the second belt conveyor 400, with the U-shaped opening facing the conveyor belt of the second belt conveyor 400. The side U-shaped strips 1010 of the two sets of bag-supporting assemblies 1000 are located on the same straight line. When pushing the fabric, the side U-shaped strips 1010 rotate to the open state under the push of the fabric. During the rotation to the open state, the bag-supporting parts 1011 of the side U-shaped strips 1010 rotate into the opened bag opening. The bag-supporting parts 1011 of the two side U-shaped strips 1010 can support both sides of the bag opening, keeping the bag opening in a stable open state. After the two side U-shaped strips 1010 are open, the fabric moves through the two side U-shaped strips 1010 to the bag on the packaging table. When the fabric is completely pushed into the bag and the fiberboard moves to the initial position, the side U-shaped strips 1010 rotate to the closed state under the action of the reset member.

[0057] To ensure the precise movement of both sides of the fabric into the side U-shaped strip 1010 for pushing the side U-shaped strip 1010, in this embodiment, the second belt conveyor 400 further includes two support plates 410 fixed to the workbench 100. Both support plates 410 are arranged along the conveyor belt's conveying direction and are located on opposite sides of the conveyor belt. The minimum distance between the two support plates 410 is less than the width of the fabric to be packaged, and the maximum distance between the two support plates 410 is greater than the width of the fabric to be packaged. After the fabric is placed on the conveyor belt, its two sides are positioned on the two support plates 410 respectively. The ends of the support plates 410 extend into the side U-shaped strip 1010, allowing the ends of the fabric to smoothly enter the side U-shaped strip 1010. When the side U-shaped strip 1010 is in a closed state, it engages with the corresponding support plate 410, ensuring that the side U-shaped strip 1010 remains in a stable closed state.

[0058] To further facilitate the movement of the fabric into the side U-shaped strip 1010, the port of the side U-shaped strip 1010 near the connecting shaft 1020 gradually widens to form a flared section 1012.

[0059] The above description is only a preferred embodiment of the present utility model, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
