Description

Technical Field

[0001] This utility model belongs to the technical field of paper bag processing equipment, and more specifically, it relates to an ear loop pasting machine. Background Technology

[0002] In the paper bag production process, attaching ear loops (such as handles, hanging ropes, and other accessories) is one of the key steps. Currently, ear loop attachment mainly relies on two methods:

[0003] Manual pasting: low efficiency (usually less than 10 pieces / minute), high labor intensity, and cannot meet the needs of large-scale production;

[0004] Existing automated equipment, while capable of semi-automatic pasting, has significant drawbacks—the capacity of a single unit is generally only 60 bags / minute (far below market demand), and its compatibility is extremely poor: different specifications of paper bags (such as differences in size, ear loop position, and opening method) require changes to the hardware structure (such as adjusting the guide rails or replacing the clamps) or replacement of some core hardware to be compatible. This forces companies to configure dedicated equipment for each type of paper bag or frequently adjust production lines, which is not only costly but also cumbersome to operate and has low changeover efficiency.

[0005] Market research indicates that there are currently over 80 types of paper bags available. Existing equipment can only attach ear loops to one or a few types of paper bags with fixed specifications, which cannot meet the flexible production needs of multiple varieties and small batches, severely restricting the improvement of paper bag production efficiency. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides an ear loop pasting machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an ear loop pasting machine, comprising a worktable, on the surface of which are sequentially arranged a roller feeding mechanism, a cutting and gluing unit, an ear loop feeding telescopic rod, a flipping feeding mechanism, a paper bag transfer track, a paper bag opening and closing telescopic rod, and an electrical control system located within the worktable; the roller feeding mechanism includes a feeding rack located on one side of the worktable surface, several upper rollers located on the feeding rack, and a driving assembly for driving the feeding rollers; the cutting and gluing unit includes a cutting module and a gluing module located at the output end of the roller feeding mechanism; the ear loop feeding telescopic rod is located at the output end of the cutting and gluing unit, and is driven by a cylinder fixed on the worktable, with a clamping part at the head of the ear loop feeding telescopic rod; the flipping feeding mechanism includes a paper bag stacking platform on the worktable, a separation component, and a pushing component; the paper bag opening and closing telescopic rod is driven by a bidirectional cylinder on the worktable, and has a push rod at the head of the paper bag opening and closing telescopic rod.

[0008] Preferably, a guide groove is provided between the discharge side of the cutting and coating unit and the paper bag transfer track, and a sliding groove is provided on the inner wall of the guide groove.

[0009] Preferably, the paper bag transfer track is a straight or arc-shaped guide groove structure, used to carry and transport single-layer paper bags to a preset pasting station.

[0010] Preferably, the cutting module includes a cutting fixture on the worktable, a drive cylinder, a servo motor, a crank-connecting rod mechanism, and a cutting blade located on the cutting fixture.

[0011] Preferably, the glue application module includes a glue application head and a small cylinder for driving the glue application head.

[0012] Preferably, the electrical control system includes a controller, a sensor group, and an execution circuit, which are electrically connected to the roller feeding mechanism, the cutter gluing unit, the ear loop feeding telescopic rod, the flipping feeding mechanism, and the paper bag opening and closing telescopic rod.

[0013] This utility model provides an ear loop bonding machine, which has the following beneficial effects:

[0014] 1. This equipment, through its compatible structural design and electrical control, enables one-click product switching. When customers need to switch paper bag product specifications, the operation is convenient and quick, without the need to modify the hardware structure or replace some hardware as with existing equipment. It can adapt to the ear loop pasting requirements of different specifications of paper bags, meet the diverse production requirements of the paper bag market, and reduce the cost and operational complexity for enterprises to configure special equipment for different specifications of paper bags or frequently adjust production lines.

[0015] 2. The original production capacity was increased from 60 pieces / minute to 85 pieces / minute through structural optimization and servo precision control. By optimizing the overall structural layout of the equipment, such as shortening the ear loop transmission path, and by using servo motors to precisely control the running speed and synchronization of each moving part, the equipment can complete more ear loop pasting work per unit time. The higher production capacity can better meet the needs of large-scale production, helping enterprises increase output and economic benefits in market competition.

[0016] 3. The equipment adopts a continuous operation mode, which reduces waiting time and improves overall production efficiency. The continuous operation process avoids the interruptions caused by changes in equipment and adjustments during production, making the production process smoother. Attached Figure Description

Detailed Implementation

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1 This utility model provides a technical solution: an ear loop pasting machine, including a roller feeding mechanism 2, a cutting and gluing unit 3, an ear loop feeding telescopic rod 4, a flipping feeding mechanism 5, a paper bag transfer track 6, a paper bag opening and closing telescopic rod 7, and an electrical control system 8; the components are connected by the track guide groove 9 to form a continuous automated operation process.

[0023] The roller feeding mechanism 2 includes a feeding rack located on one side of the workbench 1, several feeding rollers located on the feeding rack, and a driving assembly for driving the feeding rollers, for continuously conveying ear loop rolls along a preset path.

[0024] The cutting and gluing unit 3 includes a cutting module and a gluing module located at the output end of the roller feeding mechanism 2. The cutting module includes a cutting fixture on the worktable 1, a drive cylinder, a servo motor, a crank-connecting rod mechanism, and a cutting blade located on the cutting fixture. The reciprocating cutting blade precisely cuts the continuously fed ear loop material to a set length, providing an independent ear loop unit for subsequent gluing and pasting. The gluing module includes a gluing head and a small cylinder driving the gluing head. It evenly applies glue to the cut end of the ear loop (the side to be pasted onto the paper bag), ensuring sufficient adhesion between the ear loop and the paper bag (to withstand the tension of daily use of the paper bag).

[0025] The ear loop feeding telescopic rod 4 is located at the output end of the cutter glue coating unit 3. The ear loop feeding telescopic rod 4 is driven by a cylinder fixed on the worktable 1. The head of the ear loop feeding telescopic rod 4 is provided with a clamping part, which moves along the track guide groove 9 to transport the ear loop cut and coated by the cutter glue coating unit 3 from the discharge position to the target position at the opening of the paper bag.

[0026] The flipping and feeding mechanism 5 includes a paper bag stacking platform on the workbench 1, a separation component (specifically a vacuum suction cup or mechanical gripper) and a pusher, which are used to separate the manually stacked paper bags one by one and push them horizontally to the paper bag transfer track 6.

[0027] The paper bag opening and closing telescopic rod 7 is driven by a bidirectional cylinder on the workbench 1. The head of the paper bag opening and closing telescopic rod 7 is equipped with a push rod. The bidirectional cylinder drives the push rod to move along the guide groove 9 to the paper bag opening position. The paper bag opening is opened by telescopic or rotational action (forming an ear loop insertion gap), and the paper bag opening is reset and closed after the ear loop is placed.

[0028] Through modular adaptation of electrical control logic and mechanical structure (such as adjustable clamps, universal guide rails, and parameterized control programs), a "one-click switching" function is achieved—when customers need to change paper bag specifications, they only need to select the corresponding parameters (such as ear loop position and paper bag size) through the control panel, and the equipment automatically adjusts the position and action logic of each component without the need for manual hardware replacement. The collaborative control logic of the electrical control system 8 (7) includes:

[0029] 1. The sensor array monitors the status of each component in real time:

[0030] 2. A photoelectric sensor is installed at the outlet of roller feeding mechanism 2 to detect whether the ear loops are being conveyed normally;

[0031] 3. A position sensor is installed at the pasting station on the paper bag transfer track 6 to detect whether the paper bag has reached the designated position;

[0032] 4. A pressure sensor is installed at the opening and closing part of the paper bag opening telescopic rod 7 (6) to detect whether the paper bag opening is closed in place;

[0033] 5. When any sensor detects an abnormality (such as a broken ear loop or a paper bag not in place), the system will immediately pause the current cycle and sound an alarm. It will automatically resume operation after the fault is manually resolved.

[0034] The one-click switching function is achieved through the following steps: The user enters the target paper bag specification number through the control panel → The controller retrieves the corresponding preset parameters → The opening and closing angle of the paper bag opening telescopic rod 7, the conveying path of the ear strap feeding telescopic rod 4, and the cutting length of the cutter glue application unit 3 are automatically adjusted → After the adjustment is completed, the equipment continues to run. The entire switching process does not require manual hardware replacement (time ≤ 30 seconds).

[0035] The specific usage and function of this embodiment are as follows:

[0036] Step 1: Ear loop loading and pretreatment

[0037] The roller feeding mechanism 2 continuously feeds in the ear loop roll material from the previous process. The cutting unit cuts the ear loop to the set length, and at the same time, the glue application module applies glue to the cut ear loop ends (to ensure that they are firmly bonded later).

[0038] Step 2: Paper bag loading and opening

[0039] The flipping feeding mechanism 5 separates the manually stacked paper bags (to be attached with ear loops) layer by layer, and each paper bag is sent into the paper bag transfer track 6; the paper bag opening and closing telescopic rod 7 on the track moves along the guide groove to the paper bag opening position, and opens the paper bag opening through telescopic action (forming a gap that can be inserted with ear loops).

[0040] Step 3: Attach the ear loops

[0041] The ear loop feeding telescopic rod 4 picks up the cut and glued ear loop from the cutting unit and transports it along the guide rail 9 to the opening of the paper bag (at this time, the paper bag opening is open); after the ear loop is placed in place, the paper bag opening and closing telescopic rod 7 retracts back to its original position, the paper bag opening closes and clamps the ear loop, completing a single gluing.

[0042] Step 4: Cyclic Operation and Switching

[0043] The above steps are repeated cyclically, with the equipment running continuously in constant mode (without interruptions), achieving a production capacity of over 85 bags per minute. When it is necessary to switch paper bag specifications, the operator selects the target specification parameters (such as paper bag size and ear loop position) through the electrical control panel.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
