Description

Technical Field

[0001] The utility model belongs to the field of ton bags, and particularly relates to a ton bag processing mechanism. Background Technique

[0002] Materials are arranged in the ton bag. When collecting the materials, it is necessary to cut open the outer bag to let the materials flow out. Patent 202222892636.4, a bag-breaking machine with cross-type rotary knives, provides cutting in two directions. However, the materials do not move during the cutting process and need to be placed on the cutting platform and directly discharge materials below. Moreover, for large ton bags or ton bags that are not easy to completely discharge materials from small openings, such as ton bags filled with light materials such as flocculants, cotton textiles, and shredded cloth, a larger incision is required to completely discharge the materials. In the comparative document, only one rotary cutting knife is arranged horizontally and cannot completely cut horizontally. In addition, in the comparative document, the ton bag does not move during the cutting process, and the size of the cutting knife is the size of the cutting opening. If completely cut, a particularly large cutting knife needs to be set, which not only increases the cost but also occupies a large space.

[0003] In the existing discharging mechanisms, most of them directly discharge materials at the cutting position after cutting the ton bag. Such as the structures in Patent 202320541161.6, a material ton bag bag-breaking processing device, and Patent 202222892636.4, a bag-breaking machine with cross-type rotary knives. For materials with high density, large weight, and small volume, the materials can fall from the incision of the ton bag due to gravity. For materials with low density, light weight, large volume, or easy to agglomerate and entangle, etc., they cannot fall from the incision or cannot completely fall under the action of gravity, and a more thorough discharging mechanism is needed.

[0021] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the drawings and specific embodiments. As Figure 1-8As shown in the figure, a bulk bag handling mechanism includes a bulk bag driving and cutting mechanism for cutting bulk bags during transmission, a bulk bag unpacking and discharging mechanism for discharging materials during transmission, and a shredder for processing empty bulk bags, which are arranged in sequence from back to front. The bulk bag driving and cutting mechanism includes a first bulk bag conveying mechanism 2 and a cutting component for cutting the bulk bag in at least one direction from back to front. The bulk bag unpacking and discharging mechanism includes a second bulk bag conveying mechanism 6, and there is a material receiving place 60 below the second bulk bag conveying mechanism 6. In the existing bulk bag bag-breaking and discharging, it mostly occurs at one position and the discharging is not complete. In the present utility model, the bag-breaking and discharging are carried out at two positions, and the discharging is more sufficient. After discharging, the empty bulk bag can be directly and automatically processed without manual handling. The present utility model can realize bag-breaking, complete discharging, and bulk bag processing during the transmission process, so as to realize the full-automatic processing of bulk bags.

[0022] Specifically, a bulk bag driving and cutting mechanism includes a first frame 1 and a cutting component. A first bulk bag conveying mechanism 2 driven by a first driving mechanism 20 is arranged on the first frame 1. The cutting component includes a longitudinal cutting component 3 arranged at the front end of the first bulk bag conveying mechanism 2. The cutting direction of the longitudinal cutting component 3 is opposite to the bulk bag conveying direction or has an included angle within 45 degrees from the opposite direction. In the front-back direction here, it is considered that the bulk bag is conveyed from back to front. During the forward movement of the bulk bag, it passes through the longitudinal cutting component 3, and a longitudinal cut is made. The longitudinal cutting component 3 can cut the bulk bag by actively rotating or cut linearly by the speed of the bulk bag transmission while remaining stationary. Preferably, the cutting direction of the longitudinal cutting component 3 is opposite to the bulk bag conveying direction. In the present utility model, the bulk bag moves, the cutting direction of the longitudinal cutting component 3 is opposite to the bulk bag conveying direction and within a 45-degree included angle. As long as the movement of the bulk bag can form a continuous cut, there is no need to set a special driving mechanism for rotary cutting or linear cutting, which reduces the cost and increases the length of the cut in the longitudinal direction of the bulk bag, making it easier to discharge materials.

[0023] A transverse cutting component 5 is also arranged at the front end of the first frame 1. The two cutting directions of the transverse cutting component 5 and the longitudinal cutting component 3 intersect and are not parallel. Here, the transverse direction refers to the cutting direction perpendicular to the bulk bag conveying direction, and a certain angular deviation in a certain direction is allowed, as long as the transverse cutting component 5 can cut the bottom of the bulk bag and is not in the same direction as the longitudinal cutting component 3. Preferably, the transverse cutting direction is perpendicular to the bulk bag conveying direction. The transverse cutting component 5 can be a large rotary cutting knife, or it can cut the bulk bag transversely by moving without rotating, or cut the bulk bag more efficiently by moving transversely and rotating. These are all within the protection scope of the present utility model. The front-back order of the transverse cutting component 5 and the longitudinal cutting component 3 is not limited and can be set according to needs. The transverse cutting component 5 plus the longitudinal cutting component 3 can form cuts in two directions on the moving bulk bag, which is more convenient for discharging materials.

[0024] A transverse driving mechanism 52 is provided on the first frame 1. 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 transverse moving direction is the cutting direction of the transverse cutting assembly 5. Since the transverse cutting direction and the ton bag conveying direction are not opposite, it is necessary to have its own power to cut open the ton bag. In the present 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, capable of forming a longer incision on the ton bag, facilitating subsequent material discharge. Moreover, the transverse cutting knife 55 can be made smaller, saving costs and space. The transverse cutting knife 55 can be of various shapes.

[0025] The transverse cutting assembly 5 includes a transverse cutting frame 53 driven by the transverse driving mechanism 52 to move. At least one transverse cutting knife 55 driven by a transverse rotation driving mechanism 54 to rotate is provided on the transverse cutting frame 53, and the transverse cutting knife 55 is a circular cutting knife.

[0026] The longitudinal cutting assembly 3 is provided at the front end of the first frame 1. A support frame 4 is provided in front of the first frame 1. A guide rail 50 is provided on the support frame 4. The transverse cutting frame 53 is slidably provided on the guide rail 50 through a slider 51 provided at the lower end; the height of the support frame 4 is lower than the height of the first ton bag conveying mechanism 2; the transverse driving mechanism 52 is a rodless cylinder provided on the support frame 4; the movable end of the rodless cylinder is connected to the transverse cutting frame 53; the transverse rotation driving mechanism 54 includes a motor on the transverse cutting frame 53, and the motor drives the transverse cutting knife 55 rotatably provided on the transverse support frame 4 to rotate through a belt mechanism. A pulley is provided on the output shaft of the motor, and the pulley drives the transverse rotating shaft to rotate through a belt mechanism. Corresponding pulleys and the transverse cutting knife 55 are fixedly provided on the transverse rotating shaft, wherein the pulley is provided on a bearing seat through a bearing. The bearing seat is fixedly provided on the transverse cutting frame 53. The movable end of the rodless cylinder and the middle position at the bottom of the transverse cutting frame 53 can be connected by a hinged manner. The sliders 51 are provided on both sides of the bottom of the transverse cutting frame 53. The guide rails 50 are respectively provided on both sides of the rodless cylinder on the support rod. The height of the guide rail 50 can be higher than the height of the rodless cylinder. The rodless cylinder is a prior art, and the movable end is a piston located outside. These are prior arts and will not be described in detail.

[0027] The first bulk bag conveying mechanism 2 includes driving rollers 21 arranged in rows at the upper end of the first frame 1 and driven to rotate by a first driving mechanism 20. Ribs 22 for increasing friction are provided on the circumferential surface of the driving rollers 21. Preferably, the ribs 22 are evenly distributed along the circumferential direction, and the length direction is parallel to the axis of the rotating roller. The ribs 22 can be integral, or discontinuously distributed, or even dot-shaped on the circumferential surface of the driving rollers 21. The first driving mechanism 20 can be a chain drive mechanism driven by a motor. A sprocket is provided on each driving roller 21, and the driving roller at the end is driven by a motor. Adjacent driving rollers are respectively driven by a chain mechanism. Each driving roller is respectively driven by a chain mechanism to drive the adjacent driving roller. The power is transmitted by connecting the driving rollers in pairs through multiple chains. Driving multiple parallel driving rollers 21 to rotate through a chain mechanism is a prior art in the existing transmission field and will not be described in detail. It is also possible to drive multiple driving rollers 21 to rotate through a belt drive mechanism..

[0028] The longitudinal cutting assembly 3 includes a longitudinal rotating shaft 30 arranged along the width direction of the first frame 1. At least two longitudinal cutting knives 32 are fixedly arranged along the axial direction on the longitudinal rotating shaft 30. The longitudinal cutting knives 32 are circular cutting knives. A longitudinal rotation driving mechanism 31 is arranged on the first frame 1, and the longitudinal rotation driving mechanism 31 drives the longitudinal rotating shaft 30 to rotate. The longitudinal rotation driving mechanism 31 can be a motor arranged on the first frame 1. The motor drives the longitudinal rotating shaft 30 to rotate through a belt drive mechanism. The longitudinal rotating shaft 30 is rotatably arranged on a bearing seat through bearings. The bearing seat is fixed on the outer side surface of the first frame 1.

[0029] An installation cover 33 is arranged on the first frame 1 corresponding to the longitudinal rotating shaft 30 and the longitudinal cutting knives 32. An outlet is arranged at the upper end face of the installation cover 33 corresponding to the position of the longitudinal cutting knives 32. The upper end of the longitudinal cutting knives 32 extends out of the outlet. The height of the installation cover 33 is not higher than the highest position of the driving rollers 21. Setting the installation cover 33 can, firstly, reduce the exposed area of the longitudinal cutting knives 32, only leaving enough part for cutting, and reduce potential safety hazards. Secondly, it also prevents the bulk bag from getting stuck in the gap between the longitudinal cutting knives 32 when passing through, affecting the subsequent transmission.

[0030] The installation cover 33 is a hollow box structure. Both ends of the longitudinal transmission shaft 61 pass through the installation cover 33 and are provided with bearings. The bearings are arranged in the bearing seats, and the bearing seats are fixed in the boxes at both ends of the installation cover 33. The installation cover 33 is fixedly arranged at the front end of the first frame 1. The longitudinal cutting assembly 3 is arranged in the installation cover 33. The longitudinal cutting assembly 3 can be integrally installed and disassembled through the installation cover 33. Compared with the structure of directly arranging the longitudinal transmission shaft 61 on the first frame 1, the installation, disassembly and adjustment of the present invention are more convenient.

[0031] A bulk bag unpacking and discharging mechanism includes a second frame 7. A second bulk bag conveying mechanism 6 is arranged on the second frame 7, and below the second bulk bag conveying mechanism 6 is a material receiving place 60. The second bulk bag conveying mechanism 6 is provided with at least two transmission shafts 61 driven to rotate by a second driving mechanism 63 along the length direction of the second frame 7, and at least one transmission plate 62 is arranged on the transmission shaft 61 along the circumference. The maximum radial distance of the transmission plate 62 from the axis is less than the distance between the axes of two adjacent transmission shafts 61, which facilitates the transmission shaft 61 to drive the transmission plate 62 to rotate. In the present utility model, the transmission plate 62 is provided. The transmission plate 62 pushes the bulk bag forward, and the driving force is much greater than the frictional force when the transmission plate 62 is not provided. During the rotation process, the transmission plate 62 can also be inserted into the cut made in the bulk bag, so as to open the cut and facilitate the material to fall from the cut. For materials with a relatively small density, light weight, and materials that are prone to entanglement, the materials in the present utility model are more likely to fall completely.

[0032] The transmission plate 62 is an integral plate along the axial direction or several short plates arranged at intervals.

[0033] One transmission plate 62 is arranged on the transmission shaft 61, and the transmission plate 62 is an integral plate in the length direction; rounded corners are arranged at both ends of the transmission plate 62.

[0034] One or two transmission sprockets are fixedly arranged at the same-side end of each transmission shaft 61, and the transmission sprockets on adjacent transmission shafts 61 are connected by a transmission chain. The transmission shafts 61 are connected in pairs through multiple transmission chains to achieve power transmission. Of course, other connection methods can also be used. The second bulk bag conveying mechanism 6 further includes a motor arranged on the second frame 7. The motor is connected to a speed reducer, and the output shaft of the speed reducer is connected to the transmission shaft 61 at one end of the second frame 7. The transmission shaft 61 is driven to rotate synchronously through a chain transmission mechanism.

[0035] A shredder 8 for processing empty bulk bags is arranged at the front end of the second bulk bag conveying mechanism 6. The height of the shredder 8 is not higher than the height of the bulk bag conveying mechanism. The shredder 8 is used to shred and process empty bulk bags. The shredder 8 is an existing device on the market, and its specific structure will not be described in detail. A bulk bag driving and cutting mechanism for cutting a cut in the bulk bag is arranged at the rear end of the second bulk bag conveying mechanism 6.

[0036] The technology that the transmission shafts or the transmission rollers in the same row in the first bulk bag conveying mechanism and the second bulk bag conveying mechanism are simultaneously driven to rotate by a chain mechanism or a belt mechanism belongs to common technology in the transmission field and will not be described in detail.

[0037] During specific implementation: Place the bulk bag on the first bulk bag conveyor mechanism 2. Driven by the first driving mechanism 20, the bulk bag moves forward. Pass by the longitudinal cutting knife 32 to cut rows of longitudinal incisions on the bulk bag. Then move forward past the transverse cutting knife 55. While the bulk bag is moving forward, the transverse cutting knife 55 moves transversely to cut incisions in another direction on the bulk bag. The cut bulk bag arrives at the second bulk bag conveyor mechanism 6 and is driven forward by the rotating drive plate 62 on the transmission shaft 61 and discharges downward. After complete discharging, the bag moves forward to the shredder 8 for processing.

[0038] The technical features of the above-described embodiments can be combined arbitrarily. As long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. Without departing from the overall concept of the present invention, according to the technical solution of the present invention and equivalent substitution or change, and several changes and improvements made should also be regarded as the protection scope of the present invention.
