Description

Technical Field

[0001] The utility model belongs to the field of ton bags, and in particular relates to a ton bag transmission and cutting mechanism. Background Art

[0002] Ton bags are filled with materials, and when collecting the materials, the outer bags need to be cut to allow the materials to flow out. Patent 202222892636.4 A bag breaker with a cross-type wheel knife provides cutting in two directions. However, the material does not move during the cutting process, and needs to be placed on the cutting platform and dropped directly below. Moreover, for large ton bags or ton bags that are not easy to completely discharge from a small opening, such as ton bags containing lighter materials such as flocculent materials, cotton, rags, etc., a larger incision is required to completely discharge the materials. In the comparative document, only one rotating cutting knife is set in the horizontal direction, and it cannot be completely cut in the horizontal direction. In addition, the ton bag in the comparative document does not move during the cutting process, and the size of the cutter is the size of the cutting opening. If it is completely cut, a particularly large cutting knife is required, which not only increases the cost but also takes up a larger space. Summary of the Invention

[0009] The first ton bag conveying mechanism includes transmission rollers arranged in a row at the upper end of the first frame and driven to rotate by the first driving mechanism. The circumferential surface of the transmission rollers is provided with ribs for increasing friction.

[0010] The longitudinal cutting assembly includes a longitudinal rotating shaft arranged along the width direction of the first frame, and at least two longitudinal cutting knives are fixedly arranged along the axial direction on the longitudinal rotating shaft, and the longitudinal cutting knives are circular cutting knives; a longitudinal rotation drive mechanism is provided on the first frame, and the longitudinal rotation drive mechanism drives the longitudinal rotating shaft to rotate.

The terms used in the description, such as "center", "transverse", "longitudinal", "length", "width", "thickness", "height", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "clockwise", "counterclockwise", etc., to indicate the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operate in a specific orientation.

[0024] The following will combine the accompanying drawings and specific embodiments to clearly and completely describe the technical solution of the present invention. Figure 1-8As shown, a ton bag transmission and cutting mechanism comprises a first frame 1 and a cutting assembly. A first ton bag conveying mechanism 2 driven by a first drive mechanism 20 is mounted on the first frame 1. The cutting assembly includes a longitudinal cutting assembly 3 disposed at the front end of the first ton bag conveying mechanism 2. The cutting direction of the longitudinal cutting assembly 3 is opposite to the conveying direction of the ton bag, or within a 45-degree angle from the opposite direction. In the fore-and-aft direction, the ton bag is assumed to be conveyed from back to front. As the ton bag moves forward, it passes through the longitudinal cutting assembly 3, whereupon a longitudinal cut is made. The longitudinal cutting assembly 3 can cut the ton bag by actively rotating or by being stationary and performing a linear cut at the speed of the ton bag's conveyance. Preferably, the cutting direction of the longitudinal cutting assembly 3 is opposite to the conveying direction of the ton bag. In the present invention, as long as the ton bag moves and the cutting direction of the longitudinal cutting assembly 3 is opposite to the conveying direction of the ton bag and within a 45-degree angle, a dedicated rotary or linear cutting drive mechanism is not required. This reduces costs while increasing the length of the longitudinal cut of the ton bag, making it easier to cut the material.

[0025] A transverse cutting component 5 is also provided at the front end of the first frame 1, and the two cutting directions of the transverse cutting component 5 and the longitudinal cutting component 3 are not parallel to each other. The transverse here means that the cutting direction is perpendicular to the conveying direction of the ton bag, and an angular offset in a certain direction is allowed, as long as the transverse cutting component 5 can cut the bottom of the ton bag and is inconsistent with the direction of the longitudinal cutting component 3. Preferably, the transverse cutting direction is perpendicular to the conveying direction of the ton bag. The transverse cutting component 5 can be a large rotating cutting knife, or it can move without rotating to cut the ton bag transversely, or move transversely and rotate to cut the ton bag more efficiently. These are all within the scope of protection of the present utility model. The front and back order of the transverse cutting component 5 and the longitudinal cutting component 3 is not limited and can be set as needed. The transverse cutting component 5 plus the longitudinal cutting component 3 can form cuts in two directions on the moving ton bag, which can make discharging more convenient.

[0026] A transverse driving mechanism 52 is provided on the first frame 1, and the transverse cutting assembly 5 includes at least one transverse cutting knife 55 driven by the transverse driving mechanism 52 to move transversely, and the direction of transverse movement is the cutting direction of the transverse cutting assembly 5. Because the transverse cutting direction is not opposite to the conveying direction of the ton bag, it is necessary to have its own power to cut the ton bag. In the utility model, the transverse cutting knife 55 of the transverse cutting assembly 5 is driven by the transverse driving mechanism 52 to move transversely, actively cutting the ton bag, and can form a longer incision on the ton bag, which is convenient for subsequent blanking. Moreover, the transverse cutting knife 55 can be made smaller, saving cost and space. The transverse cutting knife 55 can be of various shapes.

[0027] The transverse cutting assembly 5 includes a transverse cutting frame 53 driven to move by a transverse driving mechanism 52. The transverse cutting frame 53 is provided with at least one transverse cutting knife 55 driven to rotate by a transverse rotating driving mechanism 54. The transverse cutting knife 55 is a circular cutting knife.

[0028] The longitudinal cutting assembly 3 is mounted at the front end of the first frame 1. A support frame 4 is mounted in front of the first frame 1, and a guide rail 50 is mounted on the support frame 4. The transverse cutting frame 53 is slidably mounted on the guide rail 50 via a slider 51 mounted at its lower end. The support frame 4 is lower than the height of the first bag conveyor 2. The transverse drive mechanism 52 is a rodless cylinder mounted on the support frame 4. The movable end of the rodless cylinder is connected to the transverse cutting frame 53. The transverse rotary drive mechanism 54 includes a motor mounted on the transverse cutting frame 53. The motor drives a transverse cutter 55 mounted on the transverse support frame 4 via a belt mechanism. A pulley is mounted on the motor output shaft, which drives a transverse rotating shaft via a belt mechanism. A corresponding pulley and the transverse cutter 55 are fixed to the transverse rotating shaft. The pulley is mounted on a bearing seat via a bearing. The bearing seat is fixed to the transverse cutting frame 53. The movable end of the rodless cylinder can be hinged to the center of the bottom of the transverse cutting frame 53. The sliders 51 are mounted on both sides of the bottom of the transverse cutting frame 53. The guide rails 50 are provided on both sides of the rodless cylinder on the support rod. The height of the guide rails 50 can be higher than that of the rodless cylinder. The rodless cylinder is a prior art, and the movable end is a piston located outside. These are prior art and will not be described in detail.

[0029] The first bag conveying mechanism 2 includes a row of drive rollers 21 arranged at the upper end of the first frame 1 and driven for rotation by a first drive mechanism 20. Ribs 22 are provided on the circumference of the drive rollers 21 to increase friction. The ribs 22 are preferably evenly distributed along the circumference, with their length parallel to the axis of the rotating rollers. The ribs 22 can be solid, intermittent, or even dotted around the circumference of the drive rollers 21. The first drive mechanism 20 can be a chain drive mechanism driven by a motor. Each drive roller 21 is provided with a sprocket. The end drive rollers are driven by a motor. Adjacent drive rollers are driven by a chain mechanism. Each drive roller drives its adjacent drive rollers via a chain mechanism. Multiple chains connect the drive rollers to each other to achieve power transmission. Using a chain mechanism to drive multiple parallel drive rollers 21 is a well-known technique in the transmission field and will not be described in detail. Alternatively, a belt drive mechanism can be used to drive multiple drive rollers 21.

[0030] The longitudinal cutting assembly 3 includes a longitudinal rotating shaft 30 arranged along the width of the first frame 1. At least two circular longitudinal cutting blades 32 are fixedly mounted on the longitudinal rotating shaft 30 along the axial direction. A longitudinal rotating drive mechanism 31 is mounted on the first frame 1 to drive the longitudinal rotating shaft 30 for rotation. The longitudinal rotating drive mechanism 31 can be a motor mounted on the first frame 1, which drives the longitudinal rotating shaft 30 for rotation via a belt drive mechanism. The longitudinal rotating shaft 30 is rotatably mounted on a bearing seat via a bearing. The bearing seat is fixed to the outer side of the first frame 1.

[0031] A mounting cover 33 is provided on the first frame 1, corresponding to the longitudinal rotation axis 30 and the longitudinal cutter 32. An outlet is provided on the upper end of the mounting cover 33, corresponding to the position of the longitudinal cutter 32; the upper end of the longitudinal cutter 32 extends out of the outlet. The height of the mounting cover 33 is no higher than the highest position of the transmission roller 21. The installation of the mounting cover 33 firstly reduces the exposed area of ​​the longitudinal cutter 32, leaving only enough space for cutting, thereby reducing potential safety hazards. Secondly, it also prevents large bags from getting stuck in the gap between the longitudinal cutters 32 when passing through, affecting subsequent transmission.

[0032] The mounting cover 33 is a hollow box structure. The longitudinal drive shaft 61 extends through the mounting cover 33 at both ends and is provided with bearings. The bearings are housed in bearing blocks, which are secured to the exterior of the housing at both ends of the mounting cover 33. The mounting cover 33 is fixedly mounted at the front end of the first frame 1. The longitudinal cutting assembly 3 is housed within the mounting cover 33 and can be installed and removed as a whole through the mounting cover 33. Compared to a structure in which the longitudinal drive shaft 61 is directly mounted on the first frame 1, the present invention facilitates installation, removal, and adjustment.

[0033] In addition, a ton bag unloading mechanism is located at the front end of the ton bag transmission and cutting mechanism. This mechanism comprises a second frame 7, a second ton bag conveyor mechanism 6 mounted on the second frame 7, and a material receiving station 60 located below the second ton bag conveyor mechanism 6. The second ton bag conveyor mechanism 6 is provided with at least two drive shafts 61 along the length of the second frame 7, each driven by a second drive mechanism 63. Each drive shaft 61 is provided with at least one drive plate 62 along its circumference. The maximum radial distance between the drive plate 62 and the axis is less than the distance between the axes of two adjacent drive shafts 61, facilitating the rotation of the drive plate 62 by the drive shaft 61. The provision of the drive plate 62 in the present invention propels the ton bag forward with a force far greater than the frictional force without the drive plate 62. During rotation, the drive plate 62 can also be inserted into the cutout created by the ton bag, thereby opening the cutout and facilitating the material's release. For low-density, lightweight materials that tend to tangle, the present invention facilitates the complete release of the material.

[0034] The transmission plate 62 is a whole plate or a plurality of short plates arranged at intervals along the axial direction.

[0035] A transmission plate 62 is provided on the transmission shaft 61 . The transmission plate 62 is an integral plate in the length direction. Rounded corners are provided at both ends of the transmission plate 62 .

[0036] One or two drive sprockets are fixedly mounted on one end of each transmission shaft 61 on the same side, and the drive sprockets on adjacent transmission shafts 61 are connected by a transmission chain. Multiple transmission chains connect the transmission shafts 61 in pairs to achieve power transmission. Of course, other connection methods can also be used. The second ton bag conveying mechanism 6 also includes a motor mounted on the second frame 7. The motor is connected to a reducer, and the output shaft of the reducer is connected to the transmission shaft 61 at one end of the second frame 7. The chain transmission mechanism drives the transmission shafts 61 to rotate synchronously.

[0037] A shredder 8 for handling empty ton bags is located at the front end of the second ton bag conveyor 6. Shredder 8 is no taller than the ton bag conveyor. Shredder 8 is a commercially available device, and its detailed structure will not be described in detail.

[0038] Existing ton bag breaking and emptying processes mostly occur at a single location, resulting in incomplete emptying. In this new system, bag breaking and emptying occur at two locations, resulting in more complete emptying. Empty ton bags can be automatically processed directly after emptying, eliminating the need for manual handling. This new system allows bag breaking, complete emptying, and bag processing to be achieved during the entire process, thus achieving fully automated ton bag processing.

[0039] In specific implementation, a ton bag is placed on the first ton bag conveyor mechanism 2. Driven by the first drive mechanism 20, the ton bag moves forward. The bag passes through the longitudinal cutter 32, which cuts rows of longitudinal slits into the bag. Then, the bag passes through the transverse cutter 55. As the bag moves forward, the transverse cutter 55 moves laterally, creating slits in the opposite direction. The cut ton bag then passes onto the second ton bag conveyor mechanism 6. Driven forward by the rotating drive plate 62 on the drive shaft 61, the bag falls downward. After the bag is completely shed, it moves forward to the shredder 8 for processing.

[0040] The technical features of the above-described embodiments may be combined in any manner, and as long as there are no contradictions in the combination of these technical features, they shall be deemed to be within the scope of this specification. Without departing from the overall concept of the present invention, the technical solutions of the present invention, their equivalent replacements or modifications, and certain changes and improvements made thereto shall also be deemed to be within the scope of protection of the present invention.
