Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding machine technology, specifically a bag-cutting and feeding machine. Background Technology
[0002] A feeding machine is a mechanical device used to accurately, stably, and efficiently feed various materials into designated production equipment, reaction vessels, or processing areas according to predetermined requirements. It can achieve precise control of parameters such as material feeding amount, feeding speed, and feeding frequency to meet the needs of different production processes.
[0003] An existing patent (publication number: CN213921834U) discloses a cutting device for a baggage handling machine, including a mounting base. The mounting base is equipped with a stationary blade adjustment device and a moving blade adjustment device. A stationary blade holder is located on one side of the stationary blade adjustment device, and a moving blade holder is located inside the moving blade adjustment device. A moving blade is located at the end of the moving blade holder away from the moving blade adjustment device, and a stationary blade is located at the end of the stationary blade holder away from the stationary blade adjustment device. A fixing frame is located on the upper surface of the stationary blade, and the fixing frame is fixedly connected to one end of the stationary blade holder. Both the stationary and moving blade adjustment devices are equipped with multiple sets of screws, allowing for adjustment and replacement of the stationary and moving blades according to actual working conditions. This invention allows for quick and accurate cutting of bags, adjusting the positions of the moving and stationary blades according to different working conditions. Furthermore, it is more time-saving and labor-saving than existing cutting devices on baggage handling machines for blade replacement and maintenance, and is superior to traditional methods.
[0004] During use, the aforementioned cutting device cuts the cloth bag by combining a sliding moving blade and a stationary blade. However, since the stationary blade and the moving blade are in a parallel state, the gap on the cut cloth bag will be two-dimensional. When the material inside the cloth bag is poured out, the area between the two cuts on the cloth bag will trap the material, making it difficult for the material to be completely poured out of the cloth bag. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a bag cutting and feeding machine, which has advantages such as improving cutting effect and avoiding material residue inside the bag, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a bag cutting and feeding machine, including a main frame, a hopper and a feeding platform. The hopper is fixedly installed on the upper end of the main frame by bolts. The feeding platform is hinged to the upper end of the main frame on one side along the width direction. A sliding groove is opened on the feeding platform along its length direction, and a pneumatic cutter is slidably connected along the length direction of the inner wall of the sliding groove. A drive assembly is provided on the upper end of the main frame.
[0007] The upper end of the main frame is rotatably connected to a rotating rod via a bearing seat. Two disc-shaped rotating cutters are fixedly installed on the outer circumference of the rotating rod along the middle of its axis. The bottom end of the feeding table has two notches, and the two rotating cutters are located in the corresponding notches. A motor is fixedly installed on one side of the main frame in the width direction, and one end of the rotating rod is fixedly connected to the output shaft of the motor.
[0008] Furthermore, the drive assembly includes a rodless cylinder fixedly mounted on the upper end of the bracket. The output end of the rodless cylinder is fixedly connected to the output end of the external pump body. A slide table is slidably connected to the outer circumferential surface of the rodless cylinder along the axial direction. The bottom end of the pneumatic cutter is fixedly connected to the side of the slide table by bolts.
[0009] Through the above solution, the rodless cylinder is powered by an external pump, which can control the movement speed and displacement of the slide table, thereby driving the pneumatic cutter to make stable reciprocating linear motion along the slide. It can ensure the accuracy and efficiency of the cutting operation according to the cutting requirements of different packaging forms and material characteristics.
[0010] Furthermore, one end of the feeding platform is inclined toward the hopper and located in the central area of the hopper.
[0011] The above scheme creates a natural material sliding channel by tilting the feeding platform, allowing the material to slide smoothly from the feeding platform into the hopper under the action of gravity, which greatly improves the continuity and efficiency of feeding and reduces the possibility of material accumulation and blockage.
[0012] Furthermore, the bottom of the hopper has a conical structure.
[0013] With the above design, the bottom of the hopper is designed as a cone shape, which allows the material to naturally converge to the bottom of the hopper under the action of gravity. During the feeding process, the material can slide smoothly down the cone sidewall, avoiding the accumulation and residue of material in the corners of the bottom of the hopper, and improving the utilization rate of the material.
[0014] Furthermore, the inner bottom wall of the feeding platform is polished.
[0015] The above solution, after the inner bottom wall of the feeding platform is polished, can reduce the friction between the cloth bag and the inner wall of the feeding platform during the material conveying process, so that the cloth bag can move more smoothly on the feeding platform, reduce the jamming and accumulation of the cloth bag during the conveying process, and improve the efficiency and stability of material conveying.
[0016] Furthermore, the upper ends of both sides of the feeding platform along its length are inclined outwards.
[0017] The above design, with the upper sides of the feeding platform tilted outwards, increases the material feeding range and tolerance. In actual operation, the operator does not need to place the material precisely in the center of the feeding platform. As long as the material falls roughly into the tilt range, it can smoothly slide into the feeding platform for subsequent cutting and feeding operations.
[0018] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:
[0019] This bag cutting and feeding machine, through the combined use of a pneumatic cutter and two rotary cutters, can create a T-shaped notch on the surface of the bag during cutting, allowing the material inside the bag to be completely poured out through the T-shaped notch. Secondly, the positional design of the pneumatic and rotary cutters ensures that even if the bag is placed at an angle or in a wrinkled state on the feeding platform, it can still cut the surface of the bag to create a T-shaped notch, improving the versatility and adaptability of the bag cutting and feeding equipment to bags in different placement states. It reduces cutting failures or material residue problems caused by improper bag placement. Furthermore, the overall design, with its horizontal and vertical cutting capabilities, can adapt to different packaging materials, further enhancing the practicality of the equipment.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] Please see Figure 1 , Figure 2 and Figure 3 The bag cutting and feeding machine in this embodiment includes a main frame 1, a hopper 2, and a feeding platform 3. The hopper 2 is fixedly installed on the upper end of the main frame 1 by bolts. The feeding platform 3 is hinged to the upper end of the main frame 1 on one side along the width direction. The feeding platform 3 has a sliding groove 4 along its length direction, and a pneumatic cutter 5 is slidably connected along the length direction of the inner wall of the sliding groove 4. The pneumatic cutter 5 has double-edged edges. The double-edged edges of the pneumatic cutter 5 enable the pneumatic cutter 5 to effectively cut materials in both forward and backward directions when it reciprocates linearly along the sliding groove 4, which greatly improves the cutting efficiency and flexibility and can quickly adapt to the cutting needs of different packaging forms and material characteristics. A drive assembly 6 is provided at the upper end of the main frame 1.
[0029] The upper end of the main frame 1 is rotatably connected to a rotating rod 7 via a bearing seat. Two disc-shaped rotating cutters 8 are fixedly mounted on the outer circumference of the rotating rod 7 along its central axis. The bottom end of the feeding platform 3 has two notches, and the two rotating cutters 8 are located within the corresponding notches. A gap exists between the two rotating cutters 8, which increases the cutting efficiency coverage of the bag, ensuring the bag is cut from all angles, avoiding dead angles, and ensuring the bag is fully cut open so that the material can flow out smoothly. One end of the feeding platform 3 is connected to the main frame 1... The hinge allows the rotary cutter 8 to be exposed by flipping the feed table 3 after it breaks, making it easier to replace. A motor 9 is fixedly installed on one side of the main frame 1 in the width direction, and one end of the rotating rod 7 is fixedly connected to the output shaft of the motor 9. The two rotary cutters 8 can cut the bag again after the pneumatic cutter 5 cuts it, so that the surface of the bag forms a T-shaped notch, which allows the material inside the bag to be completely poured out, avoiding the presence of material residue in the bag.
[0030] The drive assembly 6 includes a rodless cylinder 601 fixedly mounted on the upper end of the bracket. The output end of the rodless cylinder 601 is fixedly connected to the output end of an external pump. A slide table 602 is slidably connected to the outer circumferential surface of the rodless cylinder 601 along the axial direction. The bottom end of the pneumatic cutter 5 is fixedly connected to the side of the slide table 602 by bolts. The rodless cylinder 601 is powered by the external pump and can control the movement speed and displacement of the slide table 602, thereby driving the pneumatic cutter 5 to perform stable reciprocating linear motion along the slide groove 4. It can ensure the accuracy and efficiency of the cutting operation according to the cutting requirements of different packaging forms and material characteristics. The slide table 602 is fixed to the pneumatic cutter 5 by bolts, which makes it easy to disassemble and replace the broken pneumatic cutter 5 after it breaks.
[0031] One end of the feeding platform 3 is inclined towards the hopper 2 and located in the central area of the hopper 2. The inclined structure of the feeding platform 3 forms a natural material sliding channel, allowing the material to smoothly slide from the feeding platform 3 into the hopper 2 under the action of gravity. This greatly improves the continuity and efficiency of feeding and reduces the possibility of material accumulation and blockage. The bottom of the hopper 2 has a conical structure. The conical design of the bottom of the hopper 2 allows the material to naturally converge to the bottom of the hopper 2 under the action of gravity. During the feeding process, the material can slide smoothly down along the conical sidewall, avoiding the accumulation and residue of material in the corners of the bottom of the hopper 2, and improving the utilization rate of the material. The inner bottom wall of the feeding platform 3 is polished. After the inner bottom wall of the feeding platform 3 is polished, the friction between the cloth bag and the inner wall of the feeding platform 3 is reduced during the material conveying process, so that the cloth bag can move more smoothly on the feeding platform 3, reducing the jamming and accumulation of the cloth bag during the conveying process, and improving the efficiency and stability of material conveying. The upper ends of both sides of the feeding platform 3 are inclined outward along its length. The outward inclination of the upper ends of both sides of the feeding platform 3 can increase the material feeding range and fault tolerance space. In actual operation, the operator does not need to place the material precisely in the center of the feeding platform 3. As long as the material falls roughly into the inclined range, it can smoothly slide into the feeding platform 3 for subsequent cutting and feeding operations.
[0032] The working principle of the above embodiment is as follows: First, the external pump delivers gas to the rodless cylinder 601, causing the rodless cylinder 601 to drive the slide table 602 to slide back and forth on the rodless cylinder 601. During this process, the slide table 602 can drive the pneumatic cutter 5 to make reciprocating linear motion in the slide groove 4. Subsequently, the motor 9 drives the rotating rod 7 to rotate, causing the rotating rod 7 to drive the two rotating cutters 8 to rotate.
[0033] When the worker puts the cloth bag onto the feeding platform 3, the reciprocating linear motion of the pneumatic cutter 5 can cut a straight slit on the surface of the cloth bag. Since the feeding platform 3 is designed with an inclination and is polished, the cloth bag will slide to the two rotating cutters 8. When the cloth bag passes the two rotating cutters 8, the rotating cutters 8 will cut two slits on the surface of the cloth bag, which will combine with the first slit to form a T-shaped notch. After the T-shaped notch is cut, the material inside the cloth bag will tilt out without obstruction, which can prevent the material from being stuck in the cloth bag. The cut cloth bag will slide off the feeding platform 3 and fall into the hopper 2, and be discharged through the conical opening of the hopper 2.
