Description

Technical Field

[0001] This utility model relates to the field of battery material processing technology, specifically a battery material ton bag cutting and opening device. Background Technology

[0002] In the field of battery material production and processing, key raw materials such as cathode materials (e.g., ternary materials, lithium iron phosphate) and anode materials (e.g., graphite) are often stored and transported in ton-sized flexible modular containers (MTBF). These MTBFs are typically made of high-strength polypropylene woven fabric, featuring strong load-bearing capacity and good sealing performance, effectively preventing materials from getting damp, contaminated, or leaking dust.

[0003] Chinese Patent Announcement No. CN218086433U discloses a ton bag cutting device, including a platform with a feed inlet fixedly connected to the upper end. The platform has a bag-breaking mechanism inside for cutting the bags. The bag-breaking mechanism includes a cutter and a conical head. The cutter reciprocates to cut the packaging bag, and the upper end of the conical head is conical to puncture the packaging bag. In this invention, the bag-breaking mechanism drives the cutter to reciprocate, thereby automatically cutting the ton bag. The reciprocating motion of the cutter limits its maximum stroke distance, effectively reducing dust generation during cutting. Automated cutting saves labor costs, and the conical head assists in tearing and securing the ton bag, facilitating the cutter's cutting of the bag.

[0004] In existing technologies, the use of a ton bag cutting device only mentions "conical head-assisted tearing and fixing". The conical head only "punctures the packaging bag with its conical upper end", and cannot adjust the overall position of the ton bag. If the position of the ton bag is offset when it is loaded, the cutter is prone to misalignment. Furthermore, without a rigid clamping structure, the ton bag may shake due to the reciprocating force of the cutter during the cutting process, which may further lead to deviation of the cutting trajectory and affect the bag breaking effect. Therefore, we have made improvements to this and proposed a battery material ton bag cutting and opening device. Utility Model Content

This protects the respiratory health of operators, prevents dust from adhering to equipment parts and affecting operating accuracy, and avoids secondary pollution of battery materials by dust, thus meeting the requirements of environmentally friendly production.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components.

[0035] Example 1: Please refer to the appendix of the instruction manual. Figure 1-5 A battery material ton bag cutting and opening device includes a housing 1, a base 2 on one side of the housing 1, a loading platform 13 and a unloading platform 14 on opposite sides of the base 2, a first servo motor 3 fixedly installed inside the base 2, a fixed seat 4 fixedly installed at the output end of the first servo motor 3 and slidably connected to the base 2, a cutting table 5 slidably connected between the inner walls of the two sides of the base 2, a second servo motor 6 fixedly installed inside the base 2 and fixedly connected to the cutting table 5 at the output end of the second servo motor 6, a support plate 17 above the loading platform 13, a main blade 22 and a secondary blade 23 below the support plate 17, a U-shaped fixing block 16 above the support plate 17, clamping plates 8 slidably connected at the bottom of the U-shaped fixing block 16 and on opposite sides of the support plate 17, a third servo motor 9 fixedly installed inside the U-shaped fixing block 16, a bidirectional lead screw 10 fixedly installed at the output end of the third servo motor 9 and threadedly connected to the two clamping plates 8.

[0036] In this embodiment of the utility model, after the ton bag is placed on the loading platform 13, the first servo motor 3 is started, driving the fixed seat 4 to slide along the base 2, and driving the U-shaped fixed block 16 and the clamping plate 8 to move above the ton bag.

[0037] The third servo motor 9 starts and drives the bidirectional lead screw 10 to rotate. Because the bidirectional lead screw 10 is threadedly connected to the two clamping plates 8 and the threads are in opposite directions, the two clamping plates 8 slide towards each other along the bottom of the U-shaped fixing block 16 until they clamp the two sides of the ton bag to prevent the ton bag from shifting during cutting.

[0038] The second servo motor 6 starts, driving the cutting table 5 to slide along the inner wall of the base 2 and achieve angle deflection. Through the sliding connection structure between the cutting table 5 and the inner wall of the base 2, the motor drives the adjustment of the angle between the plane of the cutting table 5 and the horizontal direction. According to the shape of the ton bag, such as irregular corners or cutting requirements such as inclined cuts, the support angle of the cutting table 5 is adjusted to ensure that the ton bag is in the optimal cutting posture when it contacts the blade. At the same time, the support plate 17 drives the main blade 22 and the secondary blade 23 to move down, and complete the cutting action after contacting the ton bag.

[0039] In this embodiment of the invention, the clamping plate 8 is driven by the third servo motor 9 and the bidirectional lead screw 10 to achieve uniform clamping force and precise positioning of the ton bag, avoiding deviations caused by manual clamping and improving cutting stability. The second servo motor 6 drives the cutting table 5 to achieve angle adjustment, which can adapt to ton bags of different shapes (such as bulging or upturned corners) or special cutting needs (such as cutting along the inclined surface of the ton bag). Compared with the fixed-angle cutting table 5, it has a wider range of applicable scenarios. By adjusting the angle of the cutting table 5, the ton bag and the blade are always kept perpendicular or at the optimal contact angle, avoiding problems such as incomplete cutting and excessive blade wear caused by the tilted posture of the ton bag.

[0040] Example 2: Please refer to the appendix of the instruction manual. Figure 1-7 In a preferred embodiment of the present invention, a collection box 11 is slidably connected to the bottom of the support plate 17. A suction pipe 12 is provided on both sides of the collection box 11 and between the main blade 22 and the secondary blade 23. Both suction pipes 12 are inserted into the inside of the collection box 11 and fixedly connected thereto. Both suction pipes 12 are connected to the collection box 11. An air pump is provided on one side of the collection box 11 and passes through one side of the collection box 11 and is connected thereto.

[0041] The collection box 11 has two filter plates fixedly installed inside. The aperture of the two filter plates increases from left to right. A box plate is set at the bottom of the collection box 11 and at the bottom of the two filter plates. Fixing bolts are set at the four corners of the bottom of the box plate. Multiple fixing bolts are inserted into the inside of the collection box 11 and threadedly connected to it. Multiple fixing bolts pass through the box plate and are threadedly connected to it.

[0042] Multiple first electric telescopic rods 18 are fixedly installed inside the base 2. Limiting rods 19 are fixedly installed at the output ends of the multiple first electric telescopic rods 18, and the limiting rods 19 are slidably connected to the base 2. The multiple limiting rods 19 are inserted into the interior of the fixed seat 4 and slidably connected thereto. A side plate 20 is fixedly installed inside the fixed seat 4. An infrared sensor is embedded on one side of each of the multiple limiting rods 19.

[0043] An L-shaped fixing block 15 is fixedly installed on the top of the fixing base 4. The L-shaped fixing block 15 and the U-shaped fixing block 16 are fixedly connected. A bracket is provided at the bottom of the L-shaped fixing block 15, and the corresponding sides of the bracket are fixedly connected to the L-shaped fixing block 15.

[0044] A T-shaped plate is provided between the L-shaped fixing block 15 and the support plate 17. The T-shaped plate is inserted into the L-shaped fixing block 15 and slidably connected to it. A fourth servo motor is fixedly installed inside the L-shaped fixing block 15. A first threaded rod is fixedly installed at the output end of the fourth servo motor. The first threaded rod is rotatably connected to the L-shaped fixing block 15 and passes through the T-shaped plate and is threadedly connected to it. The support plate 17 is inserted into the T-shaped plate and slidably connected to it. The T-shaped plate passes through the bracket and is slidably connected to it.

[0045] A guide plate 7 is provided between the inner walls of both sides of the base 2 and below the cutting table 5. The guide plate 7 is fixedly connected to the base 2, and a pressure sensor is embedded in the top of the guide plate 7.

[0046] A controller 21 is embedded on one side of the housing 1. The controller 21 is electrically connected to the first servo motor 3, the second servo motor 6, the third servo motor 9, the limit rod 19, the fourth servo motor, the infrared sensor, and the pressure sensor.

[0047] In this embodiment of the utility model, when the main blade 22 and the secondary blade 23 cut the ton bag, the battery material inside the ton bag is prone to generating dust; at this time, the suction pump is started, and a negative pressure is formed inside the collection box 11; the dust is sucked into the collection box 11 through the dust suction pipe 12 between the main blade 22 and the secondary blade 23, realizing the real-time collection of dust and preventing the dust from spreading into the air.

[0048] After the dust enters the collection box 11 through the suction pipe 12, it first passes through the small-diameter filter plate on the left to intercept fine dust; then it passes through the large-diameter filter plate on the right to intercept larger particles or impurities, thus achieving graded filtration of dust. When the dust in the collection box 11 accumulates to a certain amount, unscrew the fixing bolts at the bottom of the box plate, remove the box plate, and clean the dust or impurities on the filter plate. After cleaning, reinstall the box plate and tighten the bolts.

[0049] When the first servo motor 3 drives the fixed seat 4 to slide along the base 2, the infrared sensor on one side of the limit rod 19 detects the position of the fixed seat 4 in real time to prevent the fixed seat 4 from sliding beyond its travel.

[0050] When the fixed seat 4 moves to the target position, such as above the ton bag, the first electric telescopic rod 18 is activated, pushing the limiting rod 19 further into the fixed seat 4 until the limiting rod 19 contacts the inner wall or side plate 20 of the fixed seat 4, thereby achieving precise positioning of the fixed seat 4 and preventing the fixed seat 4 from shifting during the cutting process.

[0051] In this embodiment of the utility model, the L-shaped fixing block 15 serves as an intermediate connecting member, connecting the fixing seat 4 and the U-shaped fixing block 16 into one unit, so that the sliding of the fixing seat 4 can synchronously drive the U-shaped fixing block 16 and the clamping plate 8 to move; the bracket at the bottom of the L-shaped fixing block 15 further enhances the support strength of the L-shaped fixing block 15, and avoids the L-shaped fixing block 15 from deforming due to the weight of the U-shaped fixing block 16, the clamping plate 8 and the ton bag.

[0052] When it is necessary to adjust the position of the main blade 22 and the secondary blade 23 in the horizontal direction, the fourth servo motor starts and drives the first threaded rod to rotate. Since the first threaded rod is threadedly connected to the T-shaped plate and the T-shaped plate is slidably connected to the L-shaped fixing block 15, the T-shaped plate slides along the L-shaped fixing block 15, which simultaneously drives the support plate 17 and the blade to move until they are adjusted to the target position.

[0053] When the ton bag is clamped and placed on the cutting table 5, the cutting table 5 will be subjected to the pressure of the ton bag regardless of whether the cutting table 5 is horizontal or tilted. The pressure is transmitted through the cutting table 5 to the guide plate 7 below. The pressure sensor on the top of the guide plate 7 detects the pressure value in real time and transmits the data to the controller 21 to determine whether the ton bag is placed stably (even if the cutting table 5 is tilted, it can still be determined to be in place if the pressure value reaches the preset threshold), so as to avoid the ton bag being unstable due to the change of the angle of the cutting table 5.

[0054] The controller 21, acting as the "brain" of the device, receives detection data from various sensors, including infrared sensors and pressure sensors, and sends control commands to various actuators, such as servo motors and electric telescopic rods. The device also has heat dissipation holes that cooperate with multiple motors, and dustproof nets are fixedly installed inside each of the heat dissipation holes.

[0055] Example 3: Please refer to the appendix of the instruction manual. Figure 2 and Figure 7In a preferred embodiment of this utility model, a fifth servo motor is fixedly installed inside the T-shaped plate. A second threaded rod is fixedly installed at the output end of the fifth servo motor. The second threaded rod is rotatably connected to the T-shaped plate and passes through the support plate 17 and is threadedly connected to it. A first slider is slidably connected to the bottom of the support plate 17, and a second slider is rotatably connected to the bottom of the first slider. A sixth servo motor is fixedly installed inside the support plate 17. A third threaded rod is fixedly installed at the output end of the sixth servo motor. A fourth threaded rod is rotatably connected to the support plate 17 and passes through the first slider and is threadedly connected to it. A second electric telescopic rod is fixedly installed inside the first slider. A gear is fixedly installed at the output end of the second electric telescopic rod. A rack meshes with the outer side of the gear. The gear rotates with the first slider. The gear is connected to the first slider, and the rack is slidably connected to the first slider. A connecting rod is fixedly installed at the bottom of the gear and is fixedly connected to the second slider. Two third electric telescopic rods are embedded at the bottom of the second slider, and the output ends of the two third electric telescopic rods are fixedly connected to the main blade 22 and the secondary blade 23 respectively. The main blade 22 is responsible for cutting the surface layer of the woven fabric, and the secondary blade 23 has a serrated structure and is responsible for cutting the inner sealing film. The secondary blade 23 has an existing structure and is rotated by the rotating shaft inside the secondary blade 23 driven by the sixth servo motor. The collection box 11 and the two suction pipes 12 are fixedly connected to the second slider. Infrared sensors are embedded on both sides of the bottom of the support plate 17. The controller 21 is electrically connected to the fifth servo motor, the second electric telescopic rod, the third electric telescopic rod and the infrared sensors.

[0056] In this embodiment of the utility model, the blade Y-axis adjustment is as follows: the fifth servo motor is started, which drives the second threaded rod to rotate. Since the second threaded rod is threadedly connected to the support plate 17, the support plate 17 slides along the T-shaped plate to adjust the position of the blade in the Y-axis direction.

[0057] Blade angle adjustment: The second electric telescopic rod is activated, which drives the gear to rotate. The gear meshes with the rack and drives the rack to slide. At the same time, the gear drives the second slider to rotate through the connecting rod, adjusting the cutting angle of the main blade 22 and the auxiliary blade 23, such as tilting the cutting edge of the ton bag. If the cutting table 5 has been adjusted to the tilt angle, the controller 21 can synchronously drive the second electric telescopic rod to adjust the blade angle, so that the blade and the surface of the ton bag supported by the cutting table 5 maintain the optimal cutting angle, avoiding the increase in cutting resistance caused by the excessive angle between the cutting direction and the surface of the ton bag.

[0058] Blade lifting adjustment: The third electric telescopic rod is activated, pushing the main blade 22 and the auxiliary blade 23 to move up and down, controlling the cutting depth;

[0059] Blade function division: During cutting, the main blade 22 first moves down to cut open the outer woven fabric of the ton bag; the secondary blade 23 rotates the saw tooth structure under the drive of the sixth servo motor to enhance the cutting ability and moves down to cut the inner sealing film of the ton bag; at the same time, the second slider drives the collection box 11 and the dust suction pipe 12 to move synchronously to ensure that the dust suction pipe 12 is always aligned with the cutting area.

[0060] Blade X-axis fine adjustment: The sixth servo motor starts, driving the third threaded rod to rotate, and the first slider slides along the support plate 17 to fine adjust the position of the blade in the X-axis direction to ensure precise cutting.

[0061] In this embodiment of the utility model, the blade achieves "X-axis fine adjustment + Y-axis adjustment + angle adjustment + lifting adjustment" to adapt to ton bags of different specifications and materials (such as a combination of thick woven fabric and PE sealing film). The blade angle and the cutting table 5 angle can be adjusted in tandem to form "dual-angle adaptation", further expanding the device's adaptability to irregularly shaped ton bags. Through the coordination of the blade and the cutting table 5 angle, the contact resistance between the blade and the ton bag material during cutting is reduced, the blade wear rate is reduced, and the blade service life is extended. The main blade 22 cuts through the woven fabric, and the secondary blade 23 cuts through the sealing film, avoiding incomplete cutting by a single blade (such as sealing film residue after the woven fabric is cut), and improving the integrity of opening the bag. The collection box 11, the dust suction pipe 12, and the second slider are fixed and move synchronously with the blade to ensure dust collection without dead angles throughout the cutting process, further improving the environmental protection effect.

[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
