Description

Technical Field

[0001] The invention relates to the technical field of cement production, in particular to an automatic bag taking structure and a bagging machine for a cement production line. Background Art

[0002] There are two common packaging methods for cement in the production process. One is woven bag packaging with softer material. This packaging cost is lower, but the surface shape is not easy to fix after packaging and the flatness is low, which increases the difficulty of subsequent palletizing. The other is kraft paper woven bag packaging with harder material. This packaging cost is relatively high, but due to its structural characteristics and harder material, the cement is relatively flat after packaging, with a smaller surface curvature, which is more conducive to subsequent palletizing.

[0003] When traditional bagging machines use kraft paper woven bags to bag cement, they directly pour cement into the woven bags from the discharge port of the equipment. During this process, the bottom layer of cement in the woven bags has a tendency to stretch the woven bags due to gravity. The impact kinetic energy of the cement in the falling process will cause the cement to scatter after hitting the bottom of the woven bag, and the curvature of the bottom surface of the woven bag will be larger. At the same time, during the impact of the cement falling, the density of the bottom layer of cement is higher, so that after the curvature of the bottom of the woven bag is expanded, it will maintain a larger curvature under the restriction of the high-density cement. At the same time, the high hardness of the woven bag itself will also keep a larger curvature at the bottom of the woven bag. In order not to affect the subsequent stacking, the traditional method often uses mechanical or manual shaking and patting of the packaged cement to make the packaged cement have a higher flatness. Further, the process of cement production is increased and the efficiency is reduced.

[0004] Based on this, the present invention designs an automatic bag taking structure and a bagging machine for a cement production line to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide an automatic bag taking structure and a bagging machine for a cement production line, so as to solve the problem that the traditional bagging machine proposed in the above background technology directly pours cement into the woven bag from the discharge port of the equipment when using kraft paper woven bags for bagging. In this process, the bottom cement in the woven bag has a tendency to stretch the woven bag due to gravity. The impact kinetic energy carried by the cement in the falling process will cause the cement to have a tendency to scatter after impacting the bottom of the woven bag, and the curvature of the bottom surface of the woven bag will be larger. At the same time, during the falling impact of the cement, the density of the bottom cement is higher, so that after the curvature of the bottom of the woven bag is enlarged, it will maintain a larger curvature under the restriction of the high-density cement. At the same time, the high hardness of the woven bag itself will also keep the curvature of the bottom of the woven bag larger. In order not to affect the subsequent stacking, the traditional method mostly uses machinery or manual work to shake and pat the packaged cement so that the packaged cement has a higher flatness. Further, the process of cement production is increased and the efficiency is reduced.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 8 , the present invention provides a technical solution: an automatic bag taking structure and a bagging machine for a cement production line, comprising a woven bag 11, comprising a material storage mechanism, the material storage mechanism is used to store cement produced by the cement production line;

[0034] The quantitative mechanism is arranged at the right end of the storage mechanism. The cement in the storage mechanism can be transferred to the quantitative mechanism. The quantitative mechanism is used to control the single bagging amount.

[0035] A rectangular cylinder 12 is fixedly connected to the lower end of the quantitative mechanism. A discharge mechanism is provided on the lower side of the inner wall of the rectangular cylinder 12. The discharge mechanism can seal the lower end of the rectangular cylinder 12. The quantitative mechanism is used to transfer a single bag of cement into the rectangular cylinder 12. The woven bag 11 is mounted on the rectangular cylinder 12, and the lower end of the rectangular cylinder 12 is inserted into the bottom of the woven bag 11.

[0036] A supporting mechanism, which is arranged below the rectangular tube 12 and is used to lift the woven bag 11 during the bagging process;

[0037] The bagging mechanism is arranged on the outer wall of the rectangular tube 12 , and is used to assist the woven bag 11 to be sleeved on the rectangular tube 12 .

[0038] First, the woven bag 11 is assisted by the bagging mechanism to be put on the rectangular tube 12, so that the lower end of the rectangular tube 12 is inserted into the bottom of the woven bag 11, and then the bottom of the woven bag 11 is lifted by the supporting mechanism, and at the same time the discharging mechanism is in a state of blocking the lower end of the rectangular tube 12; then the storage mechanism first transports cement to the quantitative mechanism, and then the quantitative mechanism transports the cement into the rectangular tube 12. At this time, since the lower end of the rectangular tube 12 is blocked by the discharging mechanism, the cement transported by the quantitative mechanism is now shaped in the rectangular tube 12. In this process, since the rectangular tube 12 is made of hard material and is not easy to deform, the impact in the surrounding directions generated during the cement entering the rectangular tube 12 The force is absorbed by the rectangular tube 12. Further, the supporting mechanism of the woven bag 11 is removed, and the discharge mechanism is controlled to cancel the blockage of the lower end of the rectangular tube 12. The cement that has been simply shaped in the rectangular tube 12 squeezes the bottom of the woven bag 11 downward, so that the woven bag 11 slides down along the outer wall of the rectangular tube 12 and gradually detaches from the rectangular tube 12. The corresponding cement in the rectangular tube 12 slowly slides into the woven bag 11 along the inner wall of the rectangular tube 12, so that the cement loaded into the woven bag 11 will not produce impact, and further make the density of the upper and lower layers of cement in the woven bag 11 relatively more uniform. After the woven bag 11 is loaded with cement, the surface of the woven bag 11 is smoother.

[0039] The present invention sleeves the woven bag 11 on the outer wall of the rectangular tube 12, and first loads the cement in the woven bag 11 to be loaded into the rectangular tube 12 and then transfers it to the woven bag 11, so that the packaging process can effectively reduce the impact force during the cement loading process, thereby effectively improving the flatness of the surface of the woven bag 11 after the woven bag 11 is loaded with cement, reducing the subsequent pretreatment work of stacking, and effectively improving the production efficiency of cement; at the same time, reducing the impact force during the cement loading process can also effectively reduce the amount of dust in the cement packaging process, providing a more suitable working environment for workers, and reducing the loss caused by the cement dust stirred up during the cement packaging process.

[0040] As a further solution of the present invention, the discharge mechanism includes a sealing plate 21, the front end of the sealing plate 21 is elastically rotatably connected to the inner wall of the rectangular tube 12, and the connection part is externally connected to a controllable locking mechanism, which can fix the sealing plate 21 and the rectangular tube 12. The upper end of the front surface and the rear end of the lower end surface of the sealing plate 21 are fixedly connected with a sealing strip 22, and the upper end of the sealing plate 21.

[0041] Under the elastic force of the elastic connection between the front end of the sealing plate 21 and the inner wall of the rectangular tube 12, the sealing plate 21 is in a horizontal state, and the two sealing strips 22 respectively close the gaps between the front and rear ends of the sealing plate 21 and the inner wall of the rectangular tube 12, and at the same time, the locking mechanism is locked, so that the sealing plate 21 cooperates with the two sealing strips 22 to seal the lower end of the rectangular tube 12; then the quantitative mechanism transports cement into the rectangular tube 12, and then when the rectangular tube 12 transports cement into the woven bag 11, the locking mechanism opens, so that the sealing plate 21 rotates downward under the gravity of the cement, so that the passage at the lower end of the rectangular tube 12 is opened, so that the cement in the rectangular tube 12 can fall into the woven bag 11.

[0042] As a further solution of the present invention, the quantitative mechanism includes a shell 31, the lower end of the shell 31 is fixedly connected to the upper end of the rectangular tube 12, the upper left end of the shell 31 is connected to the storage mechanism, a slide groove is longitudinally penetrated through the lower left end of the shell 31, and a slide groove is longitudinally connected to the slide groove. The slide groove is used to separate the internal space of the shell 31 in the upper and lower directions of the slide groove. A first cylinder 34 is arranged on the left side of the slide plate 33, and the output shaft of the first cylinder 34 is fixedly connected to the left end of the slide plate 33. A pushing mechanism is arranged at the lower end of the slide plate 33, and the pushing mechanism can compact the cement in the rectangular tube 12.

[0043] When the quantitative mechanism feeds material into the rectangular tube 12, correspondingly, the sealing plate 21 blocks the lower end of the rectangular tube 12; at this time, the first cylinder 34 controls the slide plate 33 to slide to the left, so that the internal space of the shell 31 above and below the slide plate 33 is connected, and further, the cement in the upper half of the space of the shell 31 falls into the rectangular tube 12 under the action of gravity until the cement is above the slide plate 33; at this time, the first cylinder 34 controls the slide plate 33 to slide to the right to cut off the cement, and then the pushing mechanism compacts the cement in the space below the slide plate 33 into the rectangular tube 12.

[0044] The present invention quantifies cement by volume, so that the equipment can effectively quantify cement of different types and densities by volume, and the cement bags packaged by the equipment have the same volume.

[0045] As a further solution of the present invention, the pushing mechanism includes a U-shaped plate 41 fixedly connected to the inner wall of the shell 31, the U-shaped plate 41 can be fitted with the lower end of the slide plate 33, and the slide plate 33 is provided with a U-shaped groove 42 vertically penetrating therefrom at a position corresponding to the U-shaped plate 41; a second cylinder 43 is fixedly connected to the upper end of the shell 31, and the output shaft of the second cylinder 43 vertically downwardly penetrates the shell 31 and the U-shaped plate 41; a push plate 44 is provided at the lower end of the U-shaped plate 41, and a slider 45 is laterally slidably connected to the upper end of the push plate 44, and the output shaft of the second cylinder 43 is fixedly connected to the slider 45; a avoidance groove 46 is longitudinally penetrated through the side wall of the shell 31 corresponding to the position of the push plate 44, the push plate 44 can be laterally slidably connected to the avoidance groove 46, a clamping groove 47 is vertically opened at the upper end of the push plate 44, and a clamping column 48 is vertically fixedly connected to the lower end of the slide plate 33 corresponding to the position of the clamping groove 47, and the clamping column 48 can be engaged with the clamping groove 47.

[0046] In the initial state, under the control of the second cylinder 43, the push plate 44 is located at the uppermost end of its own stroke, the corresponding push plate 44 is aligned with the avoidance groove 46, and the clamping groove 47 is engaged with the clamping column 48; when the quantitative mechanism transports cement into the rectangular tube 12, the slide plate 33 moves to the left and drives the push plate 44 to move to the left through the clamping column 48. At this time, the push plate 44 moves to the left relative to the slider 45, and the push plate 44 slides to the left through the avoidance groove 46. Further, the cement in the shell 31 can be transported to the rectangular tube 12 without obstacle. Then, when the slide plate 33 moves to the right to cut off the cement, the corresponding U-shaped groove 42 position on the slide plate 33 is blocked by the U-shaped plate 41. At the same time, the slide plate 33 drives the push plate 44 to move to the right. Then, when the push plate 44 is reset to the right (the corresponding push plate 44 contour coincides with the inner wall contour of the rectangular tube 12), the second cylinder 43 pushes the push plate 44 downward, so that the push plate 44 squeezes the cement downward and squeezes the cement into the rectangular tube 12 for shaping.

[0047] The present invention squeezes the cement in the rectangular tube 12 once by the push plate 44, so that the cement in the rectangular tube 12 has higher density and is more uniform, thereby avoiding the deformation of the woven bag 11 due to the low density of the internal cement, further improving the flatness of the surface of the woven bag, and avoiding the limitation of the stacking height due to surface deformation when the woven bag 11 filled with cement is stacked.

[0048] As a further solution of the present invention, the left and right side walls of the rectangular tube 12 are vertically provided with a plurality of ventilation grooves 5 arranged in an array along the longitudinal direction.

[0049] When the quantitative mechanism transports cement into the rectangular tube 12 , during the downward pressing of the cement, the original air inside the rectangular tube 12 will be squeezed out by the cement through the ventilation grooves 5 on both sides of the rectangular tube 12 .

[0050] Since the air permeability of the kraft paper woven bag 11 is extremely poor, when the rectangular tube 12 enters the cement, the original air inside the rectangular tube cannot be discharged through the woven bag 11. This results in that if the ventilation groove 5 is not provided, the air inside the rectangular tube 12 will pass upward through the falling cement into the quantitative structure. In this process, the air passing through the cement will cause the density of the cement to change, further resulting in the same weight of cement having too large a difference in volume, causing cement quantification failure.

[0051] As a further solution of the present invention, the bagging mechanism includes two fixed blocks 61 symmetrically fixedly connected to the front and rear outer walls of the rectangular tube 12. The fixed blocks 61 are vertically elastically slidably connected to the slide rod 62. The lower end of the slide rod 62 is fixedly connected to the mounting platform 63. The mounting platform 63 is elastically rotatably connected to the guide plate 64. The guide plate 64 always has a tendency to rotate toward the rectangular tube 12.

[0052] Open the woven bag 11, and insert both guide plates 64 into the bag opening of the woven bag 11, and then lift the woven bag 11. During this process, the guide plates 64 will guide the woven bag, so that the woven bag 11 will insert the rectangular tube 12 into the woven bag 11 along the guide plates 64, and then continue to lift the woven bag 11; at this time, the upper end of the woven bag 11 will be stuck with the lower end of the mounting platform 63, and further, as the woven bag 11 moves upward, the woven bag 11 will drive the mounting platform 63 to move upward, and further, the mounting platform 63 drives the guide plate 64 to move upward, so that the guide plate 64 slides upward against the outer wall of the rectangular tube 12.

[0053] As a further solution of the present invention, the support mechanism includes a lifting motor 71, which is arranged on the ground. The upper end of the output shaft of the lifting motor 71 is fixedly connected to a support plate 72, and the lifting motor 71 is used to control the support plate 72 to perform vertical controllable displacement.

[0054] After the woven bag 11 is put on the outer wall of the rectangular tube 12, the support plate 72 is controlled by the lifting motor to move to the lower end of the woven bag 11; then, as the rectangular tube 12 is filled with cement and the cement is transferred into the woven bag 11, the support plate 72 is controlled by the lifting motor 71 to gradually move downward, so that the cement in the rectangular tube 12 gradually falls into the woven bag 11.

[0055] As a further solution of the present invention, the storage mechanism includes a storage box 81, the lower right end of the storage box 81 is connected to the shell 31, and a conveyor belt 82 is embedded at the bottom of the storage box 81. The conveyor belt 82 is used to push the cement at the bottom of the storage box to the right into the shell 31.

[0056] By rotating the conveyor belt 82, the cement at the bottom of the storage box 81 moves to the right, and further makes this part of the cement fall into the shell 31. Furthermore, there is always a certain amount of cement in the space above the first slide in the shell 31; thereby, in the process of transporting the cement from the shell 31 to the rectangular tube 12, the weight of the cement in the shell 31 to the cement in the rectangular tube 12 can be controlled, and at the same time, the pressure of the cement near the slide 33 is also lower; further, the slide 33 can cut the cement at that place.

[0057] The present invention limits the total amount of cement in the shell 31 to avoid excessive weight on the cement in the rectangular tube 12 from being exerted by the shell 31, resulting in excessive pressure on the cement, making it impossible for a slide plate 33 to effectively cut the cement, and further improving the stability of the equipment.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
