Description

Technical Field

[0001] This utility model belongs to the field of cutting device technology, specifically relating to a desiccant packing machine cutting device. Background Technology

[0002] Desiccant dispensing machines are key equipment in automated packaging production lines. Their cutting devices are used to cut and dispense rolls of desiccant to a set length. Currently, commonly used cutting devices consist of a fixed cutter and a moving cutter. An electromagnet drives the moving cutter horizontally, which works in conjunction with the fixed cutter to complete the shearing. However, in practical applications, the cutting device has significant shortcomings: First, the shearing force is fixed, and when the desiccant material, thickness, or seam strength changes, it is prone to incomplete cutting or leaving tangled threads, affecting production continuity and packaging qualification rate. Second, the electromagnet and cutter wear down over time, leading to decreased driving force, increased shearing gap, and gradual deterioration of shearing performance, resulting in frequent maintenance and high costs. Third, the cutter is usually a fixed unit, making it impossible to adjust the local pressure for desiccants of different widths, resulting in poor adaptability.

[0003] Chinese patent CN214924930U discloses an automatic desiccant conveying and cutting device, including a body, a tensioning conveying mechanism, a guiding conveying mechanism, and a cutting table. This patent achieves automatic conveying and guiding of the desiccant by setting up structures such as raw material rollers, tension rollers, conveying rollers, V-shaped guide roller groups, and edge-pressing conveying rollers, with a cam-linkage mechanism driving the cutter to complete the cutting. However, the shearing force of the cutter mechanism in this patent is fixed and cannot be adjusted, making it difficult to adapt to desiccants of different materials and joint strengths, and prone to incomplete cutting. Furthermore, long-term use leads to cutter wear and increased gaps, which cannot be effectively compensated for, resulting in a continuous decline in shearing performance. Therefore, in industrial scenarios involving varying materials and the need for long-term stable operation, the reliability and adaptability of this patent remain insufficient. Utility Model Content

[0004] The purpose of this invention is to provide a desiccant packing machine cutter device that can flexibly adjust the shearing force, improve the adaptability to desiccants of different specifications, and has a simple and reliable structure with convenient adjustment and operation.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A desiccant dispensing machine cutter device includes a mounting base, a fixed cutter, and a movable cutter that cooperates with the fixed cutter for shearing. The mounting base is horizontally positioned, and the fixed cutter is fixedly positioned below the mounting base. The mounting base has several threaded holes arranged along the length of the fixed cutter. Each threaded hole is threaded with an adjusting screw, the lower end of which passes through the mounting base and directly abuts against the upper surface of the fixed cutter. A locking nut is fitted onto the adjusting screw, and the locking nut is located above the mounting base.

[0007] Furthermore, a buffer pad is provided between the fixed cutter and the bottom surface of the mounting base.

[0008] Furthermore, a buffer cap is provided at the lower end of the adjusting screw.

[0009] Furthermore, there are four adjusting screws, which are arranged at equal intervals along the length of the fixed cutter.

[0010] Furthermore, a positioning pin is fixedly installed on the mounting base, and a positioning hole is provided on the fixed cutter to cooperate with the positioning pin.

[0011] Furthermore, it also includes an inlet groove and a fixing bracket, with the fixing bracket detachably mounted at one end of the mounting base, and the inlet groove being fixedly connected to the fixing bracket.

[0012] Furthermore, the top of the inlet channel is provided with a guide vane that is inclined outward, and the angle between the guide vane and the wall of the inlet channel is 15-30°.

[0013] Furthermore, the guide vanes and the inlet groove are integrally molded.

[0014] Furthermore, the mounting bracket is detachably connected to the mounting base by bolts, and the mounting bracket has a movable groove, through which the bolts pass and are threadedly connected to the mounting base.

[0015] Furthermore, the mounting base is equipped with a spring reset component that drives the movable cutter to reset.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention features an adjustable screw on the mounting base, with its lower end directly contacting the fixed cutter. The tilt angle of the fixed cutter can be controlled by rotating the screw, thus actively adjusting the clearance between the fixed and movable cutters. This allows the device to flexibly adapt to desiccant packaging of different materials, thicknesses, and seam strengths, solving the problem of insufficient shearing force leading to incomplete cutting and improving cutting success rate and packaging qualification rate. When the shearing clearance increases due to wear from long-term use, there is no need to replace parts; simply adjusting the screw to reapply sufficient top pressure restores the ideal shearing state, thereby reducing maintenance frequency and cost and extending the overall service life of the device.

[0024] The present invention will now be described and illustrated in detail with reference to the embodiments.

[0025] Example 1

[0026] like Figure 1-4 As shown, the desiccant bagging machine cutting device includes a mounting base 1, a fixed cutter 2, and a movable cutter 3 that cooperates with the fixed cutter 2 for shearing. The mounting base 1 is horizontally positioned, and the fixed cutter 2 is fixedly positioned below the mounting base 1. The mounting base 1 has several threaded holes arranged along the length of the fixed cutter 2. Each threaded hole is threaded with an adjusting screw 4. The lower end of the adjusting screw 4 passes through the mounting base 1 and directly abuts against the upper surface of the fixed cutter 2. A locking nut 5 is fitted onto the adjusting screw 4, and the locking nut 5 is located above the mounting base 1.

[0027] A buffer pad 6 is provided between the fixed cutter 2 and the bottom surface of the mounting base 1.

[0028] A buffer cap 7 is provided at the lower end of the adjusting screw 4.

[0029] There are four adjusting screws 4, which are arranged at equal intervals along the length of the fixed cutter 2.

[0030] A positioning pin 8 is fixedly installed on the mounting base 1, and a positioning hole 9 is provided on the fixed cutter 2 to cooperate with the positioning pin 8.

[0031] It also includes an inlet groove 10 and a fixing frame 11. The fixing frame 11 is detachably mounted at one end of the mounting base 1, and the inlet groove 10 is fixedly connected to the fixing frame 11.

[0032] The top of the inlet groove 10 is provided with a guide wing 12 that is inclined outward, and the angle between the guide wing 12 and the groove wall of the inlet groove 10 is 15-30°.

[0033] The guide vane 12 and the inlet groove 10 are integrally formed.

[0034] The fixing bracket 11 is detachably connected to the mounting base 1 by bolts. The fixing bracket 11 has a moving groove, and the bolt passes through the moving groove and is threadedly connected to the mounting base 1.

[0035] The mounting base 1 is equipped with a spring reset component 13 that drives the movable cutter 3 to reset.

[0036] Working process and principle:

[0037] I. Installation and Adjustment:

[0038] First, the fixed cutter 2 is initially positioned below the mounting base 1 using the positioning pin 8 and positioning hole 9, with a buffer pad 6 placed between them. Then, each adjusting screw 4 is screwed into the threaded hole of the mounting base 1, so that the buffer cap 7 at the lower end of the adjusting screw 4 abuts against the upper surface of the fixed cutter 2. By adjusting the adjusting screw 4, the fixed cutter 2 is slightly deflected, thus achieving the optimal shearing gap between the fixed cutter 2 and the movable cutter 3. After adjustment, the locking nut 5 is tightened to lock the adjusting screw 4.

[0039] II. Material shearing:

[0040] The desiccant packaging bag enters the inlet trough 10 under the drive of the external conveying mechanism. The guide vanes 12 at the top of the inlet trough 10 can smoothly guide the desiccant packaging bag. When cutting is required, the external drive mechanism pushes the movable cutter 3 to move horizontally, so that the cutting edge of the movable cutter 3 moves relative to the cutting edge of the fixed cutter 2, thus completing the cutting of the desiccant packaging bag.

[0041] III. Reset:

[0042] After the cutting action is completed, the external driving force is removed, and the movable cutter 3 automatically resets under the elastic action of the spring reset member 13, returning to the initial position to prepare for the next cutting.

[0043] IV. Adaptation and Compensation:

[0044] When changing desiccant packaging bags with different materials, thicknesses, or seam strengths, if incomplete cutting occurs, there is no need to replace parts. Simply adjust the adjusting screw 4 to change the local angle of the fixed cutter 2, and the ideal cutting effect can be quickly restored.

[0045] With prolonged use, the cutting edges of the movable cutter 3 and the fixed cutter 2 will wear down, causing the shearing gap to naturally increase. At this time, the increased gap can be reduced by retightening the adjusting screw 4, which will lift the fixed cutter 2 upwards, restoring a tight shearing fit and effectively compensating for the performance degradation caused by wear. A buffer cap 7 is located at the lower end of the adjusting screw 4, which protects the contact surface of the fixed cutter 2 during this process.

[0046] V. Auxiliary Adjustment:

[0047] The fixed frame 11 is connected to the mounting base 1 by bolts and a movable groove, which allows for fine-tuning of the inlet groove 10 after installation, ensuring that the outlet of the inlet groove 10 is always aligned with the shearing area, further guaranteeing the accuracy of guiding the desiccant packaging bag.
