Description

Technical Field

[0001] This utility model relates to the field of paper bag flattening technology, and in particular to a paper bag flattening and packing device for storage. Background Technology

[0002] Paper bags are bags made of paper or cardboard, typically used for packaging, carrying, or storing items. Paper bags come in a wide variety of types and uses, and can be designed in various shapes, sizes, and colors to meet different needs. The materials used to make paper bags typically include kraft paper, white cardboard, and coated paper, with different paper types and thicknesses available for selection. The advantages of paper bags include being environmentally friendly, biodegradable, low-cost, and easy to print, making them widely used in daily life. Furthermore, with increasing environmental awareness, paper bags are gaining popularity as an alternative to plastic bags. Flattening paper bags is an essential and crucial step in their production process, requiring the use of a paper bag flattening device, as shown below.

[0003] A search revealed a patent with authorization announcement number CN222081080U, which discloses a flattening and packing device for paper bag storage. The device includes a connecting block, a base, a fixing component, a flattening component, and a moving component. The flattening component is located at the bottom of the connecting block, the fixing component is located at the top of the base, and the moving component is located inside the base. The fixing component includes a second slider, inside which is a connecting rod. A first spring is fixedly connected to the bottom end of the connecting rod. The top of the inner side of the second slider passes through the first slider, and a pressure rod is fixedly connected to the bottom end of the first slider. This flattening and packing device for paper bag storage, through the moving component, allows for position adjustment according to different paper bags, facilitating the fixing of the paper bags during pressing. The fixing component secures the flattened paper bags, making them easier to organize, preventing them from scattering, and facilitating subsequent packing, thus improving work efficiency.

[0004] However, the aforementioned paper bag flattening and packing device still has the following areas for improvement. For example, it can only flatten the two ends of the paper bag, making it difficult to flatten the paper bag comprehensively. This makes it easy for wrinkles and unevenness to exist in the middle of the paper bag, affecting its production quality. This is especially true when the paper bag is large in size, as wrinkles and unevenness are more likely to occur in the middle of the paper bag. Therefore, its structure needs to be improved and its practicality needs to be enhanced. Utility Model Content

[0005] This utility model discloses a paper bag flattening and packing device. It features a pressing and flattening mechanism, allowing the paper bag to be placed on a support base with its sealed end abutting against a stop block. At this point, the first cylinder is activated, extending to move the pressing plate downwards, pressing the sealed end of the paper bag to secure it. Then, the motor is started, driving the lead screw to rotate, which, in conjunction with the slider and two second sliding grooves, moves the sliding block, adjusting the position of the mounting frame and flattening roller until the flattening roller is close to the sealed end of the paper bag. The second cylinder is then activated, moving the flattening roller downwards to abut against the paper bag, where a spring compresses, creating an elastic abutment. Finally, the motor is activated again, working with the lead screw and slider to move the sliding block and flattening roller horizontally, performing a more comprehensive flattening process on the paper bag. This effectively avoids numerous wrinkles and unevenness caused by insufficient flattening, thus significantly improving the flattening quality of the paper bag. In summary, this solves the problems in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model discloses a paper bag storage and flattening packaging device, including a processing table. The bottom of the processing table is provided with multiple support legs. The top of the processing table has two first sliding grooves opened horizontally. A bearing seat is slidably installed at the two first sliding grooves. The top of the processing table is fixedly connected to an mounting seat. The mounting seat is L-shaped. The bottom of the mounting seat has two second sliding grooves opened horizontally. The interior of the mounting seat has a through movable groove between the two second sliding grooves.

[0008] A pressing and flattening mechanism includes a fixed base, a first cylinder, a pressing plate, a lead screw, a motor, a slide block, and a mounting frame. The fixed base is fixedly installed on one side of the mounting base. The first cylinder is fixedly installed through the fixed base. The top of the pressing plate is fixedly connected to the telescopic end of the first cylinder. The lead screw is rotatably installed on the top of the mounting base through two bearing seats. The motor is fixedly installed on the top of the mounting base, and the output end of the motor is connected to the shaft end of the lead screw. A slider is screwed to the outside of the lead screw.

The bottom of the slider passes through the movable groove and is fixedly connected to the top of the slide block. Two second cylinders are fixedly installed at the bottom of the slide block. A lifting seat is fixedly connected to the telescopic end of the second cylinder. Multiple springs are fixedly connected to the bottom of the lifting seat. The top of the mounting frame is fixedly connected to the bottom ends of the multiple springs. Two flattening rollers are rotatably installed inside the mounting frame.

[0009] A drive mechanism is provided, which is located at the mounting base and connected to the bottom of the support base.

[0010] Furthermore, a stop is fixedly connected to the top of the support base, and the stop is close to the mounting base.

[0011] Furthermore, multiple reinforcing support blocks are fixedly installed on the L-shaped turning surface of the mounting base, and the bottom of the mounting base is fixedly connected to the top of the processing table through two support columns, with the support columns being far away from the reinforcing support blocks.

[0012] Furthermore, two guide rods are fixedly connected to the top of the clamping plate, and the guide rods movably pass through the fixed base.

[0013] Furthermore, an anti-slip pad layer is attached and fixed to the bottom of the clamping plate, and the anti-slip pad layer is made of rubber material.

[0014] Furthermore, two telescopic plates are fixedly connected to the top of the mounting frame, and the telescopic ends of the telescopic plates are fixedly connected to the bottom of the lifting seat.

[0015] Furthermore, the driving and moving mechanism includes a third cylinder, which is fixedly installed in a through-type manner at the mounting base. A connecting plate is fixedly connected to the telescopic end of the third cylinder. The top of the connecting plate is fixedly connected to the bottom of the bearing seat, and the connecting plate is away from the mounting base.

[0016] The present invention has the following advantages over the prior art:

[0017] 1. This technical solution is equipped with a pressing and flattening mechanism, which allows the paper bag to be placed on the support seat during operation, with its sealed end abutting against the stop block. At this time, the pressing and flattening mechanism can press and fix the paper bag, as well as perform a more comprehensive flattening process. This effectively avoids the paper bag from having a large number of wrinkles and uneven areas due to insufficient flattening, thereby effectively improving the flattening quality of the paper bag and making it highly practical.

[0018] 2. This technical solution incorporates a driving mechanism that allows the carrier to move horizontally during operation until it is away from the pressure plate and flattening roller. At this point, the paper bag can be quickly and easily placed on the carrier, expanding the operator's hand operating space and effectively preventing accidental hand injuries from the pressure plate and flattening roller. The driving mechanism then moves the carrier and paper bag until the sealed end of the paper bag is below the pressure plate, allowing for the pressing, fixing, and flattening of the paper bag. Similarly, after flattening, the driving mechanism can be used to move the carrier and paper bag away from the pressure plate and flattening roller, facilitating quick and safe removal of the paper bag. This significantly improves the safety of the device. Attached Figure Description

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0030] Reference Figures 1-5 A paper bag flattening and packing device includes a processing table 1, with multiple support legs at the bottom of the processing table 1. Two first sliding grooves 2 are laterally opened on the top of the processing table 1, and a bearing seat 3 is slidably installed at each of the two first sliding grooves 2. A mounting seat 4 is fixedly connected to the top of the processing table 1. The mounting seat 4 is L-shaped, with two second sliding grooves 5 laterally opened at the bottom of the mounting seat 4. A through movable groove 6 is opened inside the mounting seat 4 between the two second sliding grooves 5. A pressing and flattening mechanism 7 includes a fixed base 701, a first cylinder 702, a pressing plate 703, a lead screw 704, a motor 705, a sliding block 706, and a mounting frame 707. The fixed base 701 is fixedly installed on one side of the mounting seat 4. The first cylinder 702 is fixedly installed through the fixed base 701. The top of the pressing plate 703 is fixedly connected to the telescopic end of the first cylinder 702. 04 is rotatably mounted on the top of the mounting base 4 via two bearing seats. The motor 705 is fixedly mounted on the top of the mounting base 4, and the output end of the motor 705 is connected to the shaft end of the lead screw 704. The lead screw 704 is externally screwed with a slider 708. The top of the slide block 706 is slidably connected to two second slide grooves 5 via multiple sliding connectors. The bottom of the slider 708 passes through the movable groove 6 and is fixedly connected to the top of the slide block 706. Two second cylinders 709 are fixedly mounted on the bottom of the slide block 706. The telescopic end of the second cylinder 709 is fixedly connected to a lifting seat 710. Multiple springs 711 are fixedly connected to the bottom of the lifting seat 710. The top of the mounting frame 707 is fixedly connected to the bottom end of the multiple springs 711. Two flattening rollers 712 are rotatably mounted inside the mounting frame 707. The drive moving mechanism 8 is located at the mounting base 4 and connected to the bottom of the bearing seat 3.

[0031] A stop block 9 is fixedly connected to the top of the bearing seat 3, and the stop block 9 is close to the mounting seat 4; multiple reinforcing support blocks 10 are fixedly installed on the L-shaped turning surface of the mounting seat 4; the bottom of the mounting seat 4 is fixedly connected to the top of the processing table 1 through two support columns 11, and the support columns 11 are away from the reinforcing support blocks 10; two guide rods 713 are fixedly connected to the top of the clamping plate 703, and the guide rods 713 move through the fixed seat 701; an anti-slip pad 714 is fixedly attached to the bottom of the clamping plate 703, and the anti-slip pad 714 is made of rubber material; two telescopic plates 715 are fixedly connected to the top of the mounting frame 707, and the telescopic ends of the telescopic plates 715 are fixedly connected to the bottom of the lifting seat 710.

[0032] In the specific implementation process, during operation, the paper bag can be placed on the support seat 3, with its sealed end abutting against the stop block 9. At this time, the first cylinder 702 can be activated, extending to move the pressing plate 703 downward, pressing the sealed end of the paper bag tightly, thereby fixing the paper bag. Then, the motor 705 can be activated, driving the lead screw 704 to rotate, which, in conjunction with the slider 708 and the two second sliding grooves 5, moves the slide block 706, adjusting the position of the mounting frame 707 and the flattening roller 712. When the flattening roller 712 approaches the sealing end of the paper bag, the second cylinder 709 is activated, which moves the flattening roller 712 down to contact the paper bag. The spring 711 is compressed, forming an elastic contact and tightness against the paper bag. Finally, the motor 705 is activated again, which, together with the lead screw 704 and slider 708, moves the slide block 706 and the flattening roller 712 to move horizontally, performing a more comprehensive flattening process on the paper bag. This effectively avoids a large number of wrinkles and uneven areas on the paper bag due to insufficient flattening, thereby effectively improving the flattening quality of the paper bag.

[0033] Among them, the stop block 9 can abut against the sealing end of the paper bag when the paper bag is placed, and position and limit the paper bag, so that the subsequent pressing plate 703 can accurately press and fix the sealing end of the paper bag.

[0034] Among them, the reinforced support block 10 and the support column 11 can effectively improve the overall stability of the mounting base 4, making it less prone to shaking.

[0035] Among them, the guide rod 713 can improve the overall stability of the pressure plate 703, making it less prone to shaking;

[0036] Among them, the anti-slip pad 714 can effectively increase the friction between the pressing plate 703 and the paper bag after they come into contact and are pressed together, thereby ensuring a good pressing and fixing effect on the paper bag.

[0037] The telescopic plate 715 allows the mounting frame 707 and the lifting seat 710 to move only vertically and horizontally, without swaying left and right, effectively improving the stability of the mounting frame 707 and the flattening roller 712. Specific Implementation Example 2:

[0039] Reference Figure 3 and Figure 6 In a preferred embodiment, the drive moving mechanism 8 includes a third cylinder 801, which is fixedly installed in a through manner at the mounting base 4. A connecting plate 802 is fixedly connected to the telescopic end of the third cylinder 801. The top of the connecting plate 802 is fixedly connected to the bottom of the bearing seat 3, and the connecting plate 802 is away from the mounting base 4.

[0040] In the specific implementation process, during operation, the third cylinder 801 can be activated first, cooperating with the connecting plate 802 and the two first sliding grooves 2 to drive the bearing seat 3 to move horizontally until the bearing seat 3 is away from the pressing plate 703 and the flattening roller 712. At this time, the paper bag can be quickly and conveniently placed on the bearing seat 3, which expands the operating space for the operator's hands and can also effectively prevent the operator's hands from being accidentally injured by the pressing plate 703 and the flattening roller 712. Then, the third cylinder 801 retracts, driving the bearing seat 3 and the paper bag to move until the sealed end of the paper bag is below the pressing plate 703. Then, the paper bag can be pressed and fixed and flattened. After the flattening work is completed, the third cylinder 801 can also be used to drive the bearing seat 3 and the paper bag away from the pressing plate 703 and the flattening roller 712, so that the paper bag can be easily, quickly and safely removed.

[0041] Working Principle: During operation, the third cylinder 801 is first activated, working in conjunction with the connecting plate 802 and the two first sliding grooves 2 to move the bearing seat 3 horizontally until it moves away from the pressing plate 703 and the flattening roller 712. At this point, the paper bag can be quickly and easily placed on the bearing seat 3, expanding the operator's hand operating space while effectively preventing accidental injury to the operator's hands from the pressing plate 703 and the flattening roller 712. Then, the third cylinder 801 retracts, moving the bearing seat 3 and the paper bag until the sealed end of the paper bag is below the pressing plate 703. At this point, the first cylinder 702 is activated, extending to move the pressing plate 703 downwards, pressing the sealed end of the paper bag to secure it. Then, the motor 705 is activated, driving the lead screw 704 to rotate, thereby coordinating... The slider 708 and the two second slide grooves 5 move the slide block 706, adjusting the position of the mounting frame 707 and the flattening roller 712 until the flattening roller 712 is close to the sealing end of the paper bag. Then, the second cylinder 709 is activated, moving the flattening roller 712 down to abut against the paper bag, and the spring 711 is compressed, forming an elastic abutment against the paper bag. Finally, the motor 705 is activated again, cooperating with the lead screw 704 and the slider 708 to move the slide block 706 and the flattening roller 712 horizontally, performing a more comprehensive flattening treatment on the paper bag, effectively avoiding a large number of wrinkles and uneven areas on the paper bag due to insufficient flattening treatment. Similarly, after the flattening work is completed, the third cylinder 801 can also be used to move the bearing seat 3 and the paper bag away from below the pressing plate 703 and the flattening roller 712, making it convenient, quick and safe to remove the paper bag.
