Description

Technical Field

[0001] The present invention belongs to the technical field of feeding equipment, and particularly relates to a uniform feeding device. Background Art

[0002] During the cigarette production process, a storage cabinet is usually used as a device for storing and transporting tobacco shred materials. Generally, a conveyor belt is arranged in the storage cabinet, and the tobacco shred material raw materials are placed on the conveyor belt and sent into the storage cabinet. The thickness of the incoming tobacco shred materials is not controlled, and it may occur that the materials are piled up very thickly in a certain place, resulting in uneven feeding of the sent materials, which is not conducive to subsequent production steps. At the same time, due to the accumulation of materials, there may also be a situation of "material collapse" in the material layer, that is, due to the gravity of the materials piled up in the upper layer, the phenomenon of compacting the materials, and lumping may occur during subsequent processing, and it is necessary to solve the lumping before further processing, which affects production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a uniform feeding device, which is used to make the materials entering the storage cabinet evenly distributed and make the material flow rate entering the storage cabinet as constant as possible, facilitating subsequent production and processing.

[0004] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows:

[0005] A uniform feeding device includes a feeding storage cabinet, a conveyor belt is arranged in the feeding storage cabinet, a detection and control unit is arranged on the conveyor belt, the detection and control unit is electrically connected to the conveyor belt, the detection and control unit is used to adjust the feeding speed according to the thickness of the incoming materials, an adjustment unit is arranged on the conveyor belt, and the adjustment unit is used to adjust the thickness of the incoming materials.

[0006] Preferably, the adjustment unit includes an adjustment rotating shaft, the adjustment rotating shaft is rotatably installed above the conveyor belt, both sides of the conveyor belt are fixedly connected with mounting arms, and the adjustment rotating shaft is rotatably installed on the mounting arms; an adjustment motor is fixedly installed on the mounting arms, and the output shaft of the adjustment motor is in transmission connection with the adjustment rotating shaft;

[0007] A connecting rod is fixedly connected to the adjustment rotating shaft, a material scraping plate is fixedly connected to the connecting rod, and the rotation direction of the adjustment rotating shaft is opposite to the feeding direction of the conveyor belt. This setting is beneficial to scrape the materials at the position with too thick material layer on the conveyor belt to the rear for feeding together, making the feeding uniform and limiting the feeding height.

[0008] Preferably, a guiding inclined surface is arranged on the material scraping plate. This setting is beneficial to improving the effect of scraping and transporting materials.

[0009] Preferably, an anti-collapse material component is provided on the adjusting rotating shaft. The anti-collapse material component includes a sleeve which is slidably mounted on the adjusting rotating shaft along the axis of the adjusting rotating shaft. An avoidance groove is formed on the side wall of the sleeve, and the connecting rod is slidably disposed in the avoidance groove;

[0010] A rack is fixedly connected to the sleeve. A plurality of picking rods are rotatably mounted on the material scraping plate, and gears are fixedly connected to the picking rods. The gears are engaged with the rack. With such a setting, it is beneficial to enable the sleeve to reciprocally slide along the length direction of the avoidance groove, and the meshing between the gear and the rack drives the picking rod to rotate to make the material uniform and fluffy.

[0011] Preferably, the sleeve passes through the mounting arm on one side. A driving connecting rod is fixedly connected to the inner wall of the sleeve, and a guiding seat is fixedly connected to the outer side of the mounting arm. A guiding groove is formed on the guiding seat to enable the driving connecting rod to reciprocate during the rotation of the sleeve. With such a setting, it is beneficial to enable the driving connecting rod to move in the guiding groove during the rotation of the sleeve with the rotating shaft, driving the sleeve to move horizontally.

[0012] Preferably, the guiding groove is a space ring around the outer wall of the guiding seat. With such a setting, it is beneficial to enable the sleeve to complete the reciprocating motion, so that the rack on the sleeve moves to drive the picking rod to rotate and complete the stirring action.

[0013] Preferably, a plurality of stirring rods are fixedly connected to the picking rod. With such a setting, it is beneficial to improve the stirring effect.

[0014] Preferably, a mounting groove is formed in the mounting arm. A rotating bearing is rotatably mounted in the mounting groove, and a ring sleeve is rotatably mounted in the rotating bearing. The ring sleeve is sleeved on the sleeve. With such a setting, it is beneficial to improve the operation stability of the equipment through the rotating bearing.

[0015] Preferably, the detection and control unit includes a height detector which is disposed at the feeding port of the feeding storage cabinet. The height detector faces the conveyor belt, and the height detector is electrically connected to the driving motor of the conveyor belt. With such a setting, it is beneficial to detect the thickness of the material layer entering the storage cabinet through the height detector and further improve the accuracy of adjustment.

[0016] The invention adopting the above technical scheme has the following advantages:

[0017] 1. By providing a material scraping plate before entering the storage cabinet and adjusting the feeding speed of the conveyor belt and the rotating speed of the adjusting rotating shaft, the materials conveyed forward on the conveyor belt will all be made to have a height lower than the lower edge of the material scraping plate under the action of the material scraping plate, making the feeding more uniform;

[0018] 2. By setting up the anti-collapse material component, during the rotation of the material scraper, the sleeve drives the rack to move horizontally as it rotates with the adjustment rotating shaft under the guiding action of the guiding groove. The horizontal movement of the rack drives the pick rod and the stirring rod fixed on the pick rod to rotate, making the materials on the conveyor belt fluffy, reducing the possibility of "material collapse" caused by excessive accumulation of materials resulting in increased density of local materials, and improving production efficiency.

[0019] 3. By setting up the height detector to detect the thickness of the material layer entering the feed storage cabinet, the accuracy of adjustment is further improved. At the same time, when it is detected that the thickness of the material layer is insufficient, the height detector sends a control signal to the control motor of the conveyor belt to control the feeding speed of the conveyor belt, adding materials to the feed storage cabinet at an approximately constant flow rate, and improving the production effect.

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the description of the drawings or the specification, similar or identical parts are denoted by the same reference numerals. The implementation manners not shown or described in the drawings are in the forms known to those of ordinary skill in the art. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", etc., are only with reference to the directions of the drawings and are not used to limit the protection scope of the present invention.

[0029] As Figures 1 to 5 shown, a uniform feeding device of the present invention includes a feeding storage cabinet 1. A conveyor belt 2 is arranged in the feeding storage cabinet 1. A detection and control unit is arranged on the conveyor belt 2. The detection and control unit is electrically connected to the conveyor belt 2. The detection and control unit is used to adjust the feeding speed according to the thickness of the incoming material. An adjusting unit is arranged on the conveyor belt 2. The adjusting unit is used to adjust the thickness of the incoming material.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 5 shown, mounting arms 4 are fixedly installed on both sides of the conveyor belt 2 by screws. An adjusting motor 5 is fixedly installed on the mounting arm 4 by screws. The adjusting unit includes an adjusting rotating shaft 3. One end of the adjusting rotating shaft 3 rotatably passes through the mounting arm 4 on which the adjusting motor 5 is installed and is connected to the output shaft of the adjusting motor 5 through a coupling. One end of a connecting rod 6 is welded on the adjusting rotating shaft 3. The other end of the connecting rod 6 is fixedly installed with a material scraping plate 7 by screws or welding. The material scraping plate 7 rotates with the adjusting rotating shaft 3.

[0031] By respectively adjusting the rotation speeds of the driving motor of the conveyor belt 2 and the adjusting motor 5, when the driving motor of the conveyor belt 2 drives the material to feed on the conveyor belt 2, the adjusting motor 5 drives the material scraping plate 7 to scrape the material on the conveyor belt 2 in the direction opposite to the feeding direction of the conveyor belt, so that the height of the material on the conveyor belt 2 that is conveyed forward will be lower than the lower edge of the material scraping plate 7 under the action of the material scraping plate 7, making the feeding more uniform and having a good effect on scraping and leveling the material.

[0032] It can be understood that a guiding inclined surface 8 is machined on the material scraping plate 7. During the rotation of the material scraping plate 7 with the adjusting rotating shaft 3, the guiding inclined surface 8 is located at the front side of the material scraping plate 7 to improve the effect of scraping the material.

[0033] Compared with the traditional fixedly arranged material scraping plate 7, the material on the conveyor belt 2 automatically feeds under the material scraping plate 7, and the material scraping plate 7 scrapes and levels the material on the conveyor belt 2 in a rotating manner, with a better scraping effect and not easily getting blocked at the feeding position of the material scraping plate 7.

[0034] As Figures 1 to 4As shown, in this embodiment, an anti-collapse material component is provided on the adjusting rotating shaft 3. The anti-collapse material component includes a sleeve 9, and the sleeve 9 is slidably mounted on the adjusting rotating shaft 3 along the axis of the adjusting rotating shaft 3. An avoidance groove 10 is formed in the side wall of the sleeve 9 along the length direction of the axis of the adjusting rotating shaft 3, and the connecting rod 6 is slidably mounted in the avoidance groove 10 to play a role in limiting and guiding.

[0035] It can be understood that in other embodiments of the present application, in order to fix the sliding direction of the sleeve 9, a first guiding chute is formed in the inner wall of the sleeve 9, and a first guiding block is welded or integrally formed on the outer wall of the adjusting rotating shaft 3. During installation, the first guiding chute is installed along the first guiding block, so that the sleeve 9 can not only rotate with the rotation of the adjusting rotating shaft 3, but also slide along the length of the adjusting rotating shaft 3 under the action of the first guiding block.

[0036] As Figure 3 and Figure 4 As shown, a rack 11 is welded or adhered to the sleeve 9, and a plurality of pick rods 12 are rotatably mounted on the material scraping plate 7. Gears 13 are welded to the pick rods 12, and the gears 13 are engaged with the rack 11.

[0037] In this embodiment, the pick rod 12 can be installed on the material scraping plate 7 by forming an installation hole in the material scraping plate 7, further processing a limiting step groove in the installation hole, integrally forming a limiting ring on the pick rod 12, and installing the pick rod 12 in the limiting step groove through the limiting ring. Under the action of the lower position of the fiber step groove, the pick rod 12 can only rotate around its axis.

[0038] As Figures 3 to 5 As shown, the sleeve 9 passes through the installation arm 4 without the installation of the adjusting motor 5, and a driving connecting rod 14 is welded to the inner wall of the end of the sleeve 9 passing through the installation arm 4. A cylindrical guiding seat 15 is welded to the outside of the installation arm 4, and a guiding groove 16 is formed in the guiding seat 15. The driving connecting rod 14 is installed in the guiding groove 16, and under the action of the guiding groove 16, the driving connecting rod 14 reciprocates during the rotation of the sleeve 9. The guiding groove 16 is a space annular structure around the outer wall of the guiding seat 15. In the axial direction of the guiding seat 15, the two ends of the guiding groove 16 are respectively located in two diameter circles of the guiding seat 15, and in the vertical direction, the two ends of the guiding groove 16 are respectively located on the upper and lower sides of the guiding seat 15.

[0039] During the process that the adjusting rotating shaft 3 drives the material scraping plate 7 to rotate through the connecting rod 6 to scrape and level the materials on the conveyor belt 2, the sleeve 9 also rotates with the adjusting rotating shaft 3. Also, since the guiding seat 15 is fixedly installed on the mounting arm 4, the driving connecting rod 14 in the sleeve 9 will move along the guiding groove 16 as the sleeve 9 rotates. Since axially of the guiding seat 15, the two ends of the guiding groove 16 are respectively located in two diameter circles of the guiding seat 15, the driving connecting rod 14 will have an axial movement during the movement in the guiding groove 16, that is, drive the sleeve 9 to reciprocate along the axis of the adjusting rotating shaft 3, so that the rack 11 moves horizontally relative to the material scraping plate 7 mounted on the adjusting rotating shaft 3, and drives the lifting rod 12 to rotate through the meshing between the gear 13 and the rack 11.

[0040] When the material scraping plate 7 levels the materials on the conveyor belt 2, the lifting rod 12 rotates synchronously and pierces into the materials, stirring the materials on the conveyor belt to become fluffy, reducing the possibility of "material collapse" caused by the increase in the density of local materials due to excessive material accumulation, and reducing the occurrence of caking during subsequent processing.

[0041] It can be understood that the shape of the lifting rod 12 is set as a cone with an inner diameter increasing from small to large, which is more convenient for piercing into the materials. In order to improve the stirring effect of the lifting rod 12, a plurality of stirring rods 17 are welded on the lifting rod 12. The stirring rods 17 move with the lifting rod 12 and pierce into the materials, rotating and stirring the materials to be fluffy to prevent material collapse. Since the feeding directions of the material scraping plate 7 and the conveyor belt 2 are opposite, the materials lifted by the lifting rod 12 and the stirring rods 17 will only fall behind the materials for re-feeding and will not spill. And, during the rotation of the adjusting rotating shaft 3, the lifting rod 12 is also rotating, so the materials are not easy to wind around the lifting rod 12.

[0042] In other embodiments of the present application, the guiding seat 15 can also be arranged inside the mounting arm 4, which can also play a guiding role. It's just that the driving connecting rod 14 moves in the spatially annular guiding groove 16, with a large working pressure. Setting the guiding seat 15 outside the mounting arm 4 is more convenient for equipment maintenance.

[0043] In this embodiment, as Figure 5 shown, a mounting groove 18 is formed in the mounting arm 4, a rotating bearing 19 is rotatably installed in the mounting groove 18, and a ring sleeve 20 is installed in the rotating bearing 19. The ring sleeve 20 is sleeved on the sleeve 9. By setting the rotating bearing 19, the operation of the adjusting rotating shaft 3 is ensured to be stable. During the operation of the equipment, the sleeve 9 has an axial reciprocating movement along the adjusting rotating shaft 3. Therefore, a ring sleeve 20 is arranged between the sleeve 9 and the rotating bearing 19, and is connected to the rotating bearing 19 through the ring sleeve 20 to reduce the wear on the rotating bearing 19.

[0044] To define the operation between the collar 20 and the sleeve 9, a second limiting block can be welded on the outer wall of the sleeve 9 corresponding to the position of the collar 20, and a second limiting sliding groove can be opened on the inner wall of the collar 20, so that the collar 20 can only rotate with the sleeve 9 under the combined limiting action of the second limiting block and the mounting groove 18, reducing the wear caused by the relative rotation between the collar 20 and the sleeve 9.

[0045] In this embodiment, as Figure 1 and Figure 2 shown, the detection and control unit includes a height detector 21, which is arranged at the feed inlet of the feed storage cabinet 1. The height detector 21 is directly opposite to the conveyor belt 2, and the height detector 21 is electrically connected to the drive motor of the conveyor belt 2.

[0046] The height detector 21 detects the height of the material on the conveyor belt 2. When the material scraper 7 fails to scrape, resulting in excessive material thickness at a certain point on the conveyor belt 2, the feeding speed of the drive motor of the conveyor belt 2 is slowed down to adjust the feeding flow rate; when the material on the conveyor belt 2 is sent to the feed storage cabinet 1 before accumulating to the corresponding thickness, the drive motor of the conveyor belt 2 is controlled to increase the feeding speed to adjust the feeding flow rate. That is, by setting the height detector 21, the thickness of the material layer entering the feed storage cabinet 1 is detected, further improving the accuracy of adjustment. At the same time, when it is detected that the thickness of the material layer is insufficient, a control signal is sent to the control motor of the conveyor belt 2 through the height detector 21 to control the feeding speed of the conveyor belt 2, and the material is added to the feed storage cabinet 1 at an approximately constant flow rate, improving the production effect.

[0047] The above has introduced in detail a uniform feeding device provided by the present invention. The description of specific embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
