Description

Technical Field

[0001] This invention relates to the field of granular material feeding technology, specifically to a granular material feeding device for cable processing. Background Technology

[0002] During the production of cables, plastic granules need to be fed into the feeding device of the extruder, where they are melted and extruded to be wrapped around copper wires.

[0003] After the plastic granules enter the feeding device, in order to ensure the uniformity of plastic melting and processing during extrusion and to ensure the production quality of cables, dehumidification and preheating are required.

[0004] Although existing extruders or their feeding devices are equipped with dehumidification and preheating mechanisms, they often only achieve heating by means of heating plates or heating grids placed in front of or behind the fan. Heating by means of heating plates can easily lead to local overheating and melting of plastic particles, and also cause uneven heating of plastic particles in different locations depending on their distance from the heat source.

[0005] When heating is achieved by setting heating meshes in front of and behind the fan, in order to obtain a better uniform heating effect, it is necessary to have a large gap between the plastic particles and maintain a certain heating time. However, the time when there is a large gap between the plastic particles is often during the feeding process. During the falling process, a large gap is generated between the plastic particles. However, the feeding time of the plastic particles is short, making it difficult to ensure the heating time while maintaining the gap between the plastic particles. This problem can be seen in the invention patent application No. 202210629706.9.

[0006] At the same time, in order to ensure the quality of cable processing, the plastic particles also need to be treated in a dust-free environment.

[0007] Therefore, a granular material feeding device for cable processing is proposed to address the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a granular material feeding device for cable processing, to solve the problems mentioned in the background art, namely, that "although existing extruders or their feeding devices are equipped with dehumidification and preheating mechanisms, they often only achieve heating by means of heating plates or heating meshes placed before and after the fan. Heating by heating plates can easily lead to local overheating and melting of plastic granules, and also results in uneven heating of plastic granules at different locations depending on their proximity to the heat source. When heating by means of heating meshes placed before and after the fan, in order to obtain a better uniform heating effect, there needs to be a large gap between the plastic granules and a certain heating time. However, the time for existing plastic granules to have a large gap is often when the plastic granules are falling. During the falling process, a large gap is generated between the plastic granules, but the time during which the plastic granules are falling is short, making it difficult to ensure both heating time and gap between the plastic granules. At the same time, in order to ensure the quality of cable processing, the plastic granules also need to be dust-free."

[0009] To achieve the above objectives, the present invention provides the following technical solution: a granular material feeding device for cable processing, comprising a support frame, a connecting cylinder, a support ring, and a storage tank fixedly connected to the top of the support frame, a mesh cylinder rotatably connected to the inner side of the right end of the connecting cylinder, the mesh cylinder comprising a solid part and a mesh part, an annular groove being formed between the solid part and the mesh part, a connecting rod being provided in the annular groove to fix the solid part and the mesh part together, one outer end of the solid part being rotatably connected to the inner side of the connecting cylinder, the outer side of the mesh part being rotatably connected to the inner side of the support ring, a collecting ring fixedly connected to the top of the support frame, the collecting ring being disposed at the bottom end of the annular groove, and a discharge pipe being connected to the bottom end of the collecting ring;

[0010] The mesh cylinder gradually slopes downwards from the inlet end to the outlet end;

[0011] The inner side of the connecting cylinder is fixedly connected to a first heating grid and a fan;

[0012] The inner side of the grid section is uniformly provided with partition plates, and the inner side of the grid section is provided with layered material drop plates. The cross-section of the material drop plates is triangular, and the two adjacent material drop plates are staggered.

[0013] Under the above configuration, the plastic pellet feeding device of the present invention can avoid the problems of local overheating caused by heating plates and uneven and insufficient heating caused by direct blowing of fans in the prior art.

[0014] When the first heating grid and the fan are working, hot air will be generated inside the grid cylinder and move forward to dry it.

[0015] In this invention, plastic granules are stored in a storage tank. During feeding, a second motor rotates, driving a screw conveyor to rotate. The rotation of the screw conveyor causes the plastic granules inside the storage tank to enter the inner side of the mesh cylinder from the conveyor tube. Simultaneously, a first motor rotates, driving a gear to rotate. The gear's rotation, in turn, drives a toothed ring on one end of the mesh section to rotate. During this rotation, the plastic granules inside the mesh section rotate with it. A partition plate divides the mesh section into several independent semi-enclosed spaces. With this configuration, when the semi-enclosed spaces are on the lower side... With the opening facing upwards, the semi-enclosed space gradually rises while the opening gradually faces downwards. During the rotation of multiple semi-enclosed spaces, the plastic granules inside the semi-enclosed spaces rise to a higher position along with the grid section and then fall. During the falling process, they continuously touch the layered material drop plates and circulate in this way until the plastic granules move to the annular groove under the action of gravity. Then, the collecting ring and the discharge pipe provide material. The staggered arrangement of the material drop plates allows the plastic granules to gradually separate, gradually increasing the gaps between them and preventing the plastic granules from blocking each other. This results in a more uniform heating and drying effect and increases the effective drying time of the plastic granules.

[0016] Meanwhile, the hot air in this invention is emitted from the connecting cylinder. When the plastic particles pass through the discharge plate, it can play the role of "shaking". During the "shaking" process, the dust on the surface of the plastic particles will be raised and blown out towards the feed end of the mesh cylinder under the action of hot air, thereby playing the role of cleaning the surface dust. The filter screen at the inlet end of the connecting cylinder is not shown.

[0017] As an optional embodiment of the granular material feeding device for cable processing described in this invention, the connecting cylinder is disposed on one side of the discharge end of the mesh cylinder, an outer cylinder is fixedly connected to the outside of the mesh part, the outer cylinder is arranged in the shape of a filter screen, a second heating mesh is disposed between the outer cylinder and the mesh part, and a filter screen is also disposed at the inlet end of the connecting cylinder.

[0018] Under the above configuration, the outer cylinder of the present invention is configured as a filter screen. When there is airflow inside the mesh cylinder, the air around the mesh cylinder will merge into the inside of the mesh cylinder. After being heated by the second heating mesh, the merged air can blow air onto the plastic particles in contact with the inner wall surface of the mesh cylinder, thereby further increasing the drying uniformity and efficiency of the plastic particles.

[0019] As an optional embodiment of the granular material feeding device for cable processing described in this invention, one end of the mesh section is provided with a toothed ring shape on the outer side, one end of the storage tank is fixedly connected to a first motor, and the end of the main shaft of the first motor is fixedly connected to a gear. The outer side of the gear meshes with the outer side of one end of the mesh section, and the mesh section is rotated by the rotation of the first motor.

[0020] As an optional embodiment of the granular material feeding device for cable processing described in this invention, the storage tank has a conveying cylinder connected to its bottom inner side, a second motor is fixedly connected to one end of the storage tank, a spiral conveying rod is fixedly connected to the end of the main shaft of the second motor, the spiral conveying rod is rotatably disposed on the inner side of the conveying cylinder, a grid disc is fixedly connected to the outer side of the conveying cylinder, the outer side of the grid disc is rotatably connected to the inner side of the grid section, and the material dropping plate is fixedly disposed on the grid disc.

[0021] As an optional embodiment of the granular material feeding device for cable processing described in this invention, the partition plate is fixedly connected to the inner side of the grid section, and the angle between the partition plate and the grid section on the side following the rotation direction of the grid section is an acute angle.

[0022] Under the above configuration, the angle between the partition plate and the grid part on the side of the grid part rotating in the same direction is an acute angle. This configuration allows the plastic particles inside the semi-enclosed space formed by the partition plate to rise to a higher position and then fall during the rotation process, increasing the gravitational potential energy and increasing the collision effect between the plastic particles and the drop plate. After the collision effect is increased, the gap between the plastic particles increases, and the dust shaking effect is increased.

[0023] As an optional embodiment of the granular material feeding device for cable processing described in this invention, the partition plate is arranged in an arc shape, and a recess is formed on one side of the partition plate along the rotation direction of the mesh section.

[0024] Under the above configuration, the present invention sets the partition plate in an arc shape. The arc-shaped partition plate forms a recessed part inside to accommodate plastic particles, which further increases the height of the plastic particles, increases the gravitational potential energy, and increases the collision effect between the plastic particles and the drop plate.

[0025] As an optional embodiment of the granular material feeding device for cable processing described in this invention, the partition plate and the inner side of the mesh section are rotatably connected by a hinge. A torsion spring is fixedly connected between one side of the partition plate and the mesh section. A slider is slidably connected to the mesh section via a slide rail. The slider is slidably disposed on the other side of the partition plate. An inclined surface is provided on the slider. The inclined surface abuts against the other end of the partition plate. The angle of the partition plate is changed by changing the contact position between the partition plate and the inclined surface by sliding the slider.

[0026] Under the above configuration, the partition plate and the inner side of the grid part in this invention are connected by a hinge. As the partition plate moves from bottom to top, the included angle between the partition plate and the grid part in this invention can gradually decrease. As the partition plate moves from bottom to top, the plastic particles in the enclosed space can achieve relatively stable feeding throughout the entire rising process, thereby reducing the situation of concentrated falling of plastic particles and further increasing the gap generated in the middle when the plastic particles fall, which further facilitates the hot air to remove moisture.

[0027] As the partition plate moves from bottom to top, the slider on one side of the partition plate is continuously squeezed by the inclined part fixedly connected to the inclined ring, so that the inclined surface of the slider continuously abuts against one end of the partition plate. The slider moves to the left continuously. During the upward movement, the angle between the partition plate and the grid part is continuously reduced. The torsion spring is used to reset the slider, and the arc part is used to reduce friction.

[0028] As an optional embodiment of the granular material feeding device for cable processing described in this invention, wherein: one end of the slider is fixedly connected to an arc portion, one end of the grid disk is fixedly connected to an inclined ring, an inclined portion is fixedly connected to the inclined ring, and the inclined portion is disposed on the rotation path of the slider.

[0029] As an optional embodiment of the granular material feeding device for cable processing described in this invention, the projection of the inclined portion on the grid portion is located at the upper end of the grid portion, and the inclined portion is located in the upstream direction of the rotation of the grid portion, and the inclined portion gradually thickens from bottom to top.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. This invention relates to a granular material feeding device for cable processing. The plastic granule feeding device avoids the problems of localized overheating caused by heating plates and uneven / insufficient heating caused by direct blowing from fans in existing technologies. When the first heating grid and fan are working, hot air is generated inside the grid cylinder, serving a drying function. In this invention, plastic granules are stored in a storage tank. During feeding, a second motor rotates, driving a screw conveyor. The rotation of the screw conveyor causes the plastic granules inside the storage tank to enter the inner side of the grid cylinder from the conveyor cylinder. Simultaneously, the first motor rotates, driving a gear. The gear's rotation drives the gear to rotate, which in turn drives the mesh section to rotate via a toothed ring on one side of the mesh section. During the rotation of the mesh section, granules enter the mesh... The plastic granules inside the unit rotate with the grid section. The partition plates divide the grid section into several independent semi-enclosed spaces. In this configuration, when the semi-enclosed space is at the bottom, the opening faces upward; as the semi-enclosed space gradually rises, the opening gradually faces downward. During the rotation of multiple semi-enclosed spaces, the plastic granules inside the semi-enclosed spaces rise with the grid section to a higher position and then fall. During the fall, they continuously touch the layered material drop plates, and this cycle continues until the plastic granules move to the annular groove under the action of gravity. Then, the collecting ring and the discharge pipe provide feeding. The staggered arrangement of the material drop plates allows the plastic granules to gradually separate, increasing the gaps between them and preventing the plastic granules from blocking each other. This results in a more uniform heating and drying effect and increases the effective drying time of the plastic granules.

[0032] 2. In this invention, the hot air is emitted from the connecting cylinder. When the plastic particles pass through the discharge plate, it can play the role of "shaking". During the "shaking" process, the dust on the surface of the plastic particles will be raised and blown out towards the feed end of the grid cylinder under the action of the hot air, thereby playing the role of cleaning the surface dust.

[0033] 3. In this invention, the outer cylinder is set in the shape of a filter screen. When there is airflow inside the mesh cylinder, the air around the mesh cylinder will merge into the inside of the mesh cylinder. After being heated by the second heating mesh, the merged air can blow air onto the plastic particles in contact with the inner wall surface of the mesh cylinder, thereby further increasing the drying uniformity and efficiency of the plastic particles.

[0034] 4. In this granular material feeding device for cable processing, the angle between the partition plate and the grid part along the rotation direction of the grid part is an acute angle. This setting allows the plastic particles inside the semi-enclosed space formed by the partition plate to rise to a higher position and then fall during the rotation process, increasing the gravitational potential energy and increasing the collision effect between the plastic particles and the dropping plate. After the collision effect is increased, the gap between the plastic particles increases, and the dust shaking effect is increased.

[0035] 5. In this invention, the partition plate is set in an arc shape. The arc-shaped partition plate forms a recessed part inside to accommodate plastic particles, which further increases the height of the plastic particles, increases the gravitational potential energy, and increases the collision effect between the plastic particles and the dropping plate.

[0036] 6. In this granular material feeding device for cable processing, the partition plate and the inner side of the mesh section are connected by a hinge. As the partition plate moves from bottom to top, the angle between the partition plate and the mesh section gradually decreases. This allows for more stable feeding of the plastic granules in the enclosed space during the upward movement, reducing the concentration of falling plastic granules and increasing the gap between them as they fall. This further facilitates the removal of moisture by hot air. During the upward movement of the partition plate, the slider on one side of the partition plate is continuously squeezed by the inclined part fixedly connected to the inclined ring, causing the inclined surface of the slider to continuously abut against one end of the partition plate. The slider moves continuously to the left, and the angle between the partition plate and the mesh section decreases continuously during the upward movement. The torsion spring is used for resetting, and the arc-shaped part reduces friction. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1

[0049] Please see Figure 1-5 The present invention provides a technical solution:

[0050] A feeding device for granular materials in cable processing includes a support frame 1. A connecting cylinder 2, a support ring 9, and a storage tank 12 are fixedly connected to the top of the support frame 1. A mesh cylinder is rotatably connected to the inner side of the right end of the connecting cylinder 2. The mesh cylinder includes a solid part 3 and a mesh part 15. An annular groove 5 is formed between the solid part 3 and the mesh part 15. A connecting rod 4 is provided in the annular groove 5 to fix the solid part 3 and the mesh part 15. The outer side of one end of the solid part 3 is rotatably connected to the inner side of the connecting cylinder 2. The outer side of the mesh part 15 is rotatably connected to the inner side of the support ring 9. A collecting ring 6 is fixedly connected to the top of the support frame 1. The collecting ring 6 is located at the bottom end of the annular groove 5. The bottom end of the collecting ring 6 is connected to a discharge pipe 7.

[0051] The mesh cylinder gradually slopes downwards from the inlet end to the outlet end;

[0052] The first heating mesh 16 and the fan 17 are fixedly connected to the inner side of the connecting cylinder 2.

[0053] The inner side of the aforementioned grid section 15 is uniformly provided with partition plates 20, and the inner side of the aforementioned grid section 15 is provided with layered material drop plates 19. The cross-section of the aforementioned material drop plates 19 is triangular, and two adjacent material drop plates 19 are arranged in an alternating manner.

[0054] Under the above configuration, the plastic pellet feeding device of the present invention can avoid the problems of local overheating caused by heating plates and uneven and insufficient heating caused by direct blowing of fans in the prior art.

[0055] When the first heating grid 16 and the fan 17 are working, hot air will be generated on the inside of the grid cylinder to achieve the function of drying.

[0056] In this invention, plastic granules are stored in a storage tank 12. During feeding, a second motor 14 rotates, which in turn drives a screw conveyor 18 to rotate. The rotation of the screw conveyor 18 causes the plastic granules inside the storage tank 12 to enter the inner side of the mesh cylinder through the conveyor cylinder 13. Simultaneously, a first motor 11 rotates, which in turn drives a gear 10 to rotate. The rotation of the gear 10 drives the mesh section 15 to rotate via a toothed ring on one side. During the rotation of the mesh section 15, the plastic granules that have entered the mesh section 15 rotate with it. The partition plate 20 divides the mesh section 15 into several independent semi-enclosed spaces. When the semi-enclosed space is lowered, the opening faces upward. As the semi-enclosed space gradually rises, the opening gradually faces downward. During the rotation of multiple semi-enclosed spaces, the plastic particles inside the semi-enclosed space will rise to a higher position with the grid part 15 and then fall. During the falling process, they will continuously touch the layered material drop plates 19 and continue to circulate until the plastic particles move to the annular groove 5 under the action of gravity. Then, the material is fed by the collecting ring 6 and the discharge pipe 7. The staggered arrangement of the material drop plates 19 can make the plastic particles gradually separate and the gaps between them gradually increase, avoiding the plastic particles from blocking each other, thereby achieving a more uniform heating and drying effect and increasing the effective drying time of the plastic particles.

[0057] Meanwhile, the hot air in this invention is emitted from the connecting cylinder 2. When the plastic particles pass through the discharge plate 19, it can play the role of "shaking". During the "shaking" process, the dust on the surface of the plastic particles will be raised and blown out towards the feed end of the mesh cylinder under the action of hot air, thereby playing the role of cleaning the surface dust. The filter screen at the inlet end of the connecting cylinder 2 is not shown.

[0058] In a specific implementation scenario, the connecting cylinder 2 is located on the discharge end side of the mesh cylinder, and an outer cylinder 8 is fixedly connected to the outside of the mesh part 15. The outer cylinder 8 is arranged in the shape of a filter screen, and a second heating mesh 27 is arranged between the outer cylinder 8 and the mesh part 15. A filter screen is also arranged at the inlet end of the connecting cylinder 2.

[0059] Under the above configuration, the outer cylinder 8 is configured as a filter screen. When there is airflow inside the mesh cylinder, the air around the mesh cylinder will merge into the inside of the mesh cylinder. After being heated by the second heating mesh 27, the merged air can blow air onto the plastic particles in contact with the inner wall surface of the mesh cylinder, thereby further increasing the drying uniformity and efficiency of the plastic particles.

[0060] In a specific implementation scenario, one end of the aforementioned mesh section 15 is arranged in a toothed ring shape on the outer side, and one end of the aforementioned storage tank 12 is fixedly connected to a first motor 11. The end of the main shaft of the aforementioned first motor 11 is fixedly connected to a gear 10, and the outer side of the aforementioned gear 10 meshes with the outer side of one end of the mesh section 15. The mesh section 15 is rotated by the rotation of the aforementioned first motor 11.

[0061] In a specific implementation scenario, the storage tank 12 is connected to the inner side of the bottom end of the conveying cylinder 13. A second motor 14 is fixedly connected to one end of the storage tank 12. A spiral conveying rod 18 is fixedly connected to the end of the main shaft of the second motor 14. The spiral conveying rod 18 is rotatably arranged inside the conveying cylinder 13. A grid disk 23 is fixedly connected to the outer side of the conveying cylinder 13. The outer side of the grid disk 23 is rotatably connected to the inner side of the grid part 15. The material drop plate 19 is fixedly arranged on the grid disk 23.

[0062] In a specific implementation scenario, the partition plate 20 is fixedly connected to the inner side of the grid section 15, and the angle between the partition plate 20 and the grid section 15 along the rotation direction of the grid section 15 is an acute angle.

[0063] Under the above configuration, the angle between the partition plate 20 and the grid part 15 along the rotation direction of the grid part 15 is an acute angle. This configuration allows the plastic particles inside the semi-enclosed space formed by the partition plate 20 to rise to a higher position and then fall during the rotation process, increasing the gravitational potential energy and increasing the collision effect between the plastic particles and the drop plate 19. After the collision effect is increased, the gap between the plastic particles increases, and the dust shaking effect is increased.

[0064] In a specific implementation scenario, the aforementioned partition plate 20 is arranged in an arc shape, and a recessed portion 24 is formed on one side of the partition plate 20 along the rotation direction of the grid portion 15.

[0065] Under the above configuration, the present invention sets the partition plate 20 in an arc shape. The arc-shaped partition plate 20 forms a recess 24 inside for accommodating plastic particles, which further increases the height of the plastic particles, increases the gravitational potential energy, and increases the collision effect between the plastic particles and the drop plate 19.

[0066] Example 2

[0067] This embodiment is an optional alternative to Embodiment 1. The same parts will not be repeated; the differences are as follows: Please refer to [link to previous text]. Figure 1-3 and 6-9;

[0068] The partition plate 20 and the inner side of the grid section 15 are rotatably connected by a hinge. A torsion spring 25 is fixedly connected between one side of the partition plate 20 and the grid section 15. A slider 26 is slidably connected to the grid section 15 via a slide rail. The slider 26 is slidably disposed on the other side of the partition plate 20. An inclined surface 261 is provided on the slider 26. The inclined surface 261 abuts against the other end of the partition plate 20. The angle of the partition plate 20 is changed by changing the contact position between the partition plate 20 and the inclined surface 261 by sliding the slider 26.

[0069] Under the above configuration, the partition plate 20 and the inner side of the mesh part 15 in this invention are connected by a hinge. As the partition plate 20 moves from bottom to top, the included angle between the partition plate 20 and the mesh part 15 can gradually decrease. As the partition plate 20 moves from bottom to top, the plastic particles in the enclosed space can achieve relatively stable feeding throughout the entire rising process, thereby reducing the situation of concentrated falling of plastic particles and further increasing the gap generated in the middle when the plastic particles fall, which further facilitates the hot air to remove moisture.

[0070] As the partition plate 20 moves from bottom to top, the slider 26 on one side of the partition plate 20 is continuously squeezed by the inclined part 22 fixedly connected to the inclined ring 21, so that the inclined surface 261 of the slider 26 continuously abuts against one end of the partition plate 20. The slider 26 continuously moves to the left. During the upward movement, the angle between the partition plate 20 and the grid part 15 is continuously reduced. The torsion spring 25 is used to reset the position, and the arc part 262 can reduce friction.

[0071] In a specific implementation scenario, one end of the slider 26 is fixedly connected to an arc portion 262, one end of the grid disk 23 is fixedly connected to an inclined ring 21, an inclined portion 22 is fixedly connected to the inclined ring 21, and the inclined portion 22 is arranged on the rotation path of the slider 26.

[0072] In a specific implementation scenario, the projection of the inclined portion 22 onto the grid portion 15 is located at the upper end of the grid portion 15, and the inclined portion 22 is located in the upstream direction of the rotation of the grid portion 15, with the inclined portion 22 gradually thickening from bottom to top.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
