Description

Technical Field

[0001] The utility model relates to the technical field of glass sand production, in particular to automatic packaging equipment for glass sand production. Background Art

[0002] Glass sand is a basic material widely used in casting, construction, chemical industry and other fields. The packaging link in its production process is crucial to ensuring product quality and improving production efficiency. With the development trend of industrial automation and intelligent manufacturing, traditional manual or semi-automatic packaging methods are gradually being replaced by efficient and precise fully automatic packaging equipment.

[0003] In glass sand packaging operations, existing equipment faces significant operational challenges during the filling stage. To ensure that the bag opening remains fully expanded throughout the filling process, the current practice relies on continuous manual intervention or the use of additional support devices. Frequent adjustments to the discharge valve are required based on the bag's condition. This operating method not only increases operational complexity but also brings higher maintenance requirements. More importantly, it limits the speed and efficiency of the production line, making it unable to adapt to the high output and continuous production standards pursued by modern industry. In the long run, frequent valve operations may also accelerate equipment aging and increase the risk of failure, thereby affecting product quality and customer satisfaction. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figures 1 to 7 The automatic packaging equipment for glass sand production includes a mounting frame 1, a discharging bin 2 is provided on the mounting frame 1, and a discharging pipe 3 is embedded in the discharging bin 2. The glass yarn inside the discharging bin 2 is guided to the discharging pipe 3 below by gravity or an auxiliary conveying device, and is discharged smoothly through the discharging pipe 3. Preferably, the interior of the discharging bin 2 can be equipped with a device for improving the flow efficiency of the material. Since it is a prior art, it is not described here.

[0027] A first fixing block 4 is fixedly mounted on the mounting frame 1, and a second fixing block 5 is fixedly mounted on the first fixing block 4 via a connecting column 6. An opening mechanism is provided on the connecting column 6, which can open the mouth of the packaging bag to ensure that the material enters the bag body smoothly and completes the loading activity.

[0028] The mounting frame 1 is provided with a driving mechanism, and the first fixing block 4 and the second fixing block 5 are slidably provided with a shielding mechanism.

[0029] There are two spreading mechanisms, each of which includes a movable plate 9 . Spreading blocks 10 are fixedly mounted on the two movable plates 9 , and the movement directions of the two spreading mechanisms are opposite.

[0030] By making the two movable plates 9 move synchronously in opposite directions, the bag body can be expanded. Then, through the cooperation of the expansion block 10 and the first fixed block 4 or the second fixed block 5, the edges of the packaging bag can be clamped synchronously. In this way, during the loading process, the packaging bag can always be in an expanded state without the need for manual continuous expansion, which is convenient for use.

[0031] The driving mechanism includes a stepper motor 8 and a bidirectional lead screw 13. The stepper motor 8 is installed on the mounting frame 1. There are two bidirectional lead screws 13. A synchronous chain 7 is installed between the two bidirectional lead screws 13 through a sprocket. The shaft output end of the stepper motor 8 is fixedly connected to one of the bidirectional lead screws 13.

[0032] A lead screw nut 14 is threadedly mounted on the bidirectional lead screw 13 , and the lead screw nut 14 is fixedly connected to the corresponding movable plate 9 .

[0033] The start of the stepper motor 8 drives the corresponding bidirectional lead screw 13 to rotate, and the synchronous rotation of the two bidirectional lead screws 13 is achieved through the transmission of the synchronous chain 7, and then the movable plate 9 is driven to move through the lead screw nut 14 to realize the action of the expansion mechanism.

[0034] Preferably, the transmission between the bidirectional lead screw 13 and the synchronous chain 7 can be a tooth transmission or a chain transmission, so as to ensure the transmission ratio and avoid the occurrence of slippage.

[0035] The threaded portion of the bidirectional lead screw 13 is located inside the connecting column 6 , and the lead screw nut 14 is slidably mounted inside the connecting column 6 , which ensures that the lead screw nut 14 can only perform translational motion without deflection.

[0036] There are two screw nuts 14 on a single bidirectional screw 13, and the two screw nuts 14 on the bidirectional screw 13 are respectively located in different thread directions of the bidirectional screw 13. This design allows the screw nuts 14 to move in opposite directions, thereby realizing the effective expansion and contraction of the support block 10.

[0037] There are two lead screw nuts 14 on a single movable plate 9. The two lead screw nuts 14 on the movable plate 9 are respectively located in the same thread direction of different bidirectional lead screws 13, which can ensure that the movable plate 9 moves smoothly under the joint action of the two bidirectional lead screws 13, thereby improving the stability and accuracy of the system.

[0038] The shielding mechanism includes a blocking plate 11, which is slidably mounted on the first fixed block 4 and the second fixed block 5. A discharge hole 16 aligned with the discharge pipe 3 is provided at the center of the blocking plate 11, and a driving mechanism is provided on the blocking plate 11.

[0039] During the bag changing interval, the sealing plate 11 is moved by the driving mechanism, so that the sealing plate 11 can block the discharge pipe 3 to prevent material leakage; when the packaging bag is ready, the driving mechanism causes the sealing plate 11 to slide, and while realizing the expansion and clamping activities of the packaging bag, the discharge hole 16 can be aligned with the discharge pipe 3, thereby allowing the material to flow out smoothly.

[0040] The driving mechanism includes a driving gear 12 and a passive rack 15. The driving gear 12 is fixedly mounted on the bidirectional lead screw 13. The passive rack 15 is fixedly mounted on the side of the blocking plate 11 facing the driving gear 12. The driving gear 12 and the passive rack 15 are in meshing relationship.

[0041] As the bidirectional lead screw 13 rotates, the active gear 12 drives the passive rack 15 to move, thereby causing the blocking plate 11 to slide along the track, thereby achieving the function of blocking or opening the discharge pipe 3.

[0042] Preferably, the moving distance of the blocking plate 11 can be adjusted by adjusting the size of the driving gear 12 and the matching passive rack 15, so that the blocking plate 11 can effectively block the discharge pipe 3 and avoid accidental leakage due to the long movement path.

[0043] When the opening block 10 abuts against the first fixing block 4 or the second fixing block 5 , the discharge hole 16 can be smoothly aligned with the discharge pipe 3 to realize the discharge movement.

[0044] Preferably, the first fixing block 4 , the second fixing block 5 and the blocking plate 11 may be made of a transparent material to facilitate the operator to observe the activities in real time.

[0045] A rubber pad 17 is embedded on the side of the discharge pipe 3 facing the sealing plate 11. The rubber pad 17 is always in contact with the sealing plate 11. Through the cooperation between the rubber pad 17 and the sealing plate 11, the discharge pipe 3 can always be inside the discharge pipe 3, which can prevent material leakage and ensure cleanliness.

[0046] The working process of the present invention; in the initial state, the sealing plate 11 covers the discharge pipe 3, the discharge hole 16 is not aligned with the discharge pipe 3, and the discharge port opening mechanism is completely closed and is in the initial position, which can ensure that no material flows out accidentally during the replacement of the packaging bag and keep the working environment clean.

[0047] The bag opening is opened so that the opening block 10 is inside the bag body. Then the stepper motor 8 is started, and the two bidirectional lead screws 13 are driven to rotate through the sprocket and the synchronous chain 7. The two synchronous movable plates 9 expand outward to open the packaging bag opening, and the opening block 10 cooperates with the first fixed block 4 or the second fixed block 5 to clamp the edges of both sides of the packaging bag. Then the operator can let go.

[0048] During this process, as the bidirectional lead screw 13 rotates, the active gear 12 drives the passive rack 15 to move, and the sealing plate 11 slides to a specific position. While achieving the clamping activity of the packaging bag, the alignment activity of the discharge hole 16 and the discharge pipe 3 can be achieved, and the material begins to flow into the already opened packaging bag.

[0049] In the subsequent process, the expansion mechanism remains in the expanded state, and the blocking mechanism no longer interferes with the operation of the discharge pipe 3, ensuring that the material is accurately filled into the packaging bag until the preset weight or the predetermined time (which can be selected by yourself) is reached. The stepper motor 8 rotates in the opposite direction, driving all components back to the initial position, the expansion mechanism contracts, releasing the packaging bag, and the blocking plate 11 covers the discharge pipe 3 again, preparing for the next packaging cycle.

[0050] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
