Description

Technical Field

[0001] The utility model relates to the technical field of feeding and bag breaking, in particular to a two-way feeding and bag breaking device. Background Art

[0002] In a production environment with low automation, workers usually manually break open packaging bags using knives or special tools. This method has low efficiency, high labor intensity, and safety hazards; early automated bag breaking devices were usually one-way, capable of breaking open bags only from one direction and feeding materials only in one direction, restricting the speed and flexibility of the production line.

[0003] With the rapid development of China's economy, the requirements for packaging speed and efficiency in various industries are getting higher and higher. In industries such as chemical engineering, food, and pharmaceuticals, bagged materials are widely used. However, the current bag breaking devices on the market can only achieve feeding in a single direction and can no longer meet the market demand. If feeding at different times on both sides is to be achieved, two devices need to be set up, occupying a large floor space, resulting in an unreasonable on-site layout. At the same time, the traditional bag breaking mechanism cannot confirm whether the bag breaking knife has completely broken the bag. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above technical deficiencies, provide a two-way feeding and bag breaking device, and solve the technical problems of low bag breaking efficiency and inability to meet the two-way feeding requirement in the technical field of feeding and bag breaking.

[0007] Compared with the prior art, the beneficial effects of the utility model include:

[0008] 1. High bag breaking efficiency: The two-way feeding and bag breaking device provided by the utility model adopts four bag breaking mechanisms. The bag breaking mechanism is provided with a movable bag breaking knife and bag breaking rods.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 , this embodiment provides a two-way feeding bag-breaking device, including: a hopper 1 and a bag-breaking mechanism 2.

[0022] The bag-breaking mechanism 2 includes a bag-breaking cutter 21, a bag-breaking base 22 and a cutter moving drive source 25. The output end of the cutter moving drive source 25 is fixedly connected to the bottom end of the bag-breaking cutter 21. The bag-breaking cutter 21 is vertically arranged and slides on the upper end of the bag-breaking base 22. A cutter housing 23 is provided at the upper end of the bag-breaking base 22. Specifically, the cutter housing 23 mainly supports the material bag to facilitate the bag-breaking cutter 21 to cut the material bag. The bag-breaking cutter 21 slides in a cutter groove 23a opened in the cutter housing 23 to prevent the bag-breaking cutter 21 from interfering with the movement of the cutter housing 23. The bag-breaking base 22 is fixedly provided with bag-breaking rods 24. A plurality of the bag-breaking rods 24 are vertically arranged in an array on both sides of the bag-breaking base 22. Four of the bag-breaking mechanisms 2 are arranged along the diagonal of the hopper 1.

[0023] Specifically, use a robotic arm to place the material bag into the hopper 1. At this time, the bag-breaking rods 24 first insert into the material bag to fix the material bag. Secondly, the cutter moving drive source 25 works to drive the bag-breaking cutter 21 to move back and forth, so as to use the bag-breaking cutter 21 to cut the material bag, so that the material in the material bag flows downward.

[0024] In the first embodiment, the tool movement drive source 25 is selected as a cylinder. The cylinder as the tool movement drive source has the following advantages: 1. Easy to maintain: The structure of the cylinder is relatively simple without complex electronic components, so it is relatively easy to maintain and the maintenance cost is low; 2. Quick response: The cylinder can quickly respond to control signals to achieve fast actions, which is particularly important on production lines that require high-speed operation; 3. Durability: The design of the cylinder enables it to maintain a long service life even in harsh working environments, such as high-temperature, high-humidity or dusty environments. Specifically, the end of the output shaft of the cylinder is fixedly connected to one end of the bag-breaking tool. When the output shaft of the cylinder expands and contracts, it drives the forward and backward movement of the bag-breaking tool, thereby cutting the material bag.

[0025] In the second embodiment, the tool movement drive source 25 is selected as a lead screw-slider mechanism. The advantages of the lead screw-slider mechanism as the tool movement source are: 1. High load-bearing capacity: The lead screw-slider mechanism can withstand large loads, suitable for application scenarios that require high load-bearing capacity, and can bear the weight of the material bag and the material inside the bag; 2. High efficiency and low friction: The precision-machined lead screw and slider can provide high-efficiency transmission performance, and at the same time the friction is relatively low, reducing energy loss; 3. Long service life: Due to the use of wear-resistant materials and high-precision machining, the lead screw-slider mechanism usually has a long service life. Specifically, the lead screw-slider mechanism includes a slider, a motor and a lead screw. The slider is threadedly slidably connected to the lead screw. The output shaft of the motor is fixedly connected to the lead screw to drive the forward and backward movement of the slider, so that the bottom end of the bag-breaking tool is fixedly connected to the slider. When the slider moves back and forth, it drives the bag-breaking tool to move back and forth.

[0026] Furthermore, the discharge port of the hopper 1 communicates with the feed ports of the first feeding chute 3 and the second feeding chute 4. The first feeding chute 3 and the second feeding chute 4 are symmetrically arranged with respect to the hopper 1.

[0027] Furthermore, a hopper support 5 is provided at the lower end of the hopper 1, and a base support 6 is provided at the lower end of the hopper support 5. The first feeding chute 3 and the second feeding chute 4 are both placed on a tray. The tray 8 is fixedly connected to the base support 6 through a connecting and fixing member 7; the first feeding chute 3 and the second feeding chute 4 are arranged at an angle with the base support 6; one end of the first feeding chute 3 is hinged to one end of the second feeding chute 4.

[0028] Specifically, the tray is placed at the bottom corners of the first feeding chute 3 and the second feeding chute 4, that is, it supports the first feeding chute 3 and the second feeding chute 4.

[0029] Further, the first feeding chute 3 and the second feeding chute 4 respectively include a first chute bottom plate 31 and a second chute bottom plate 41. The first chute bottom plate 31 is hinged to an output end of the flap driving source 10 through a mounting bracket 9, and the second chute bottom plate 41 is hinged to the other output end of the flap driving source 10 through the mounting bracket 9.

[0030] Preferably, the flap driving source 10 is selected as a single-ear double-acting cylinder. A single-ear double-acting cylinder is a type of pneumatic actuator. It uses compressed air as a power source to drive the piston of the cylinder to perform linear reciprocating motion. Single-ear: It means that there is a mounting ear seat (or called an earring, trunnion) at one end of the cylinder, which is used to fix and guide the cylinder. This ear seat is usually located at a certain end of the cylinder and is used to connect or fix to the equipment. And "single-ear" means there is only one such ear seat; Double-acting: This means that both ends of the cylinder can intake or exhaust air. In a working cycle, compressed air alternately enters from the air chambers at both ends of the cylinder, pushing the piston to reciprocate. Specifically: When compressed air enters the air chamber at one end of the cylinder, the piston moves from one end to the other; when the air chamber at this end exhausts air and the other end intakes air, the piston returns from the other end. A single-ear double-acting cylinder can achieve bidirectional movement without an additional return force source.

[0031] Specifically, when it is necessary to open the first feeding chute 3 for discharging materials, the output shaft of the flap driving source 10 close to the second chute bottom plate 41 extends, giving an upward turning force to the second feeding chute 4, so that the outlet end of the second feeding chute 4 faces upward, that is, the second feeding chute 4 cannot discharge materials. At this time, the outlet end of the first feeding chute 3 still faces downward and can still discharge materials.

[0032] Similarly, when it is necessary to open the second feeding chute 4 for discharging materials, the output shaft of the flap driving source 10 close to the first chute bottom plate 31 extends, and the output shaft close to the second chute bottom plate 41 retracts, giving an upward turning force to the first feeding chute 3, so that the outlet end of the first feeding chute 3 faces upward, that is, the first feeding chute 3 cannot discharge materials. At this time, the outlet end of the second feeding chute 4 still faces downward and can still discharge materials.

[0033] The flap driving source 10 changes the direction of its outlet by driving the rotation of the first feeding chute 3 and the second feeding chute 4, thereby realizing the one-way feeding of the first feeding chute 3 and the second feeding chute 4. At the same time, the first feeding chute and the second feeding chute share a hopper 1, which greatly saves the floor space of the device and realizes the two-way feeding requirement.

[0034] Furthermore, a plurality of detection and sensing units 12 are installed on the periphery of the hopper bracket 5 through a support frame 11. A plurality of pairs of the detection and sensing units 12 are oppositely arranged on both sides of the bag-breaking cutter 21 for detecting the presence of the bag-breaking cutter 21. Among them, the detection and sensing unit 12 includes a transmitting end and a receiving end, and the transmitting end and the receiving end are oppositely arranged on both sides of the bag-breaking cutter 21. When the bag-breaking cutter 21 advances to the maximum stroke of the output shaft of the cutter movement driving source, the detection and sensing unit 12 can detect the presence of the bag-breaking cutter 21 so as to determine the feed amount of the blade, ensuring the stability of the device.

[0035] Working principle: The two-way feeding bag-breaking device provided by the utility model includes a hopper 1 and a bag-breaking mechanism 2. The bag-breaking mechanism 2 includes a bag-breaking cutter 21, a bag-breaking base 22 and a cutter movement driving source. The output end of the cutter movement driving source is fixedly connected to the bottom end of the bag-breaking cutter 21. The bag-breaking cutter 21 is vertically arranged and slides on the upper end of the bag-breaking base 22. A cutter housing 23 is arranged on the upper end of the bag-breaking base 22, and the bag-breaking cutter 21 slides in a cutter groove 23a formed in the cutter housing 23. The bag-breaking base 22 is fixedly provided with bag-breaking rods 24, and a plurality of the bag-breaking rods 24 are vertically arranged in an array on both sides of the bag-breaking base 22. Four of the bag-breaking mechanisms 2 are arranged along the diagonal of the hopper 1.

[0036] Specifically, the four groups of the bag-breaking mechanisms 2 greatly improve the bag-breaking efficiency. By using the first feeding chute 3 and the second feeding chute 4 installed on both sides of the base bracket 6 and sharing the same hopper 1, the floor space is greatly saved, and the two-way feeding requirement is realized.

[0037] The above specific embodiments of the present utility model do not constitute a limitation on the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model shall be included in the protection scope of the claims of the present utility model.
