Description

Technical Field

[0001] This invention belongs to the technical field of material conveying equipment, and specifically relates to a material thickness uniformity adjustment device. Background Technology

[0002] In cigarette production, electronic belt scales are a common piece of equipment. Before the tobacco and auxiliary materials are mixed, the electronic belt scale weighs the tobacco and various mixed auxiliary materials in proportion. However, existing electronic belt scales can only perform simple weighing operations.

[0003] Chinese patent CN106768224B discloses an electronic belt scale that can loosely blend thin tobacco shreds, increasing the contact area between the tobacco shreds and the rake spikes, and further reducing the gaps between the rake spikes through a fixed rake spike mechanism, thus improving the uniformity of tobacco shred dispersion. However, it does not adjust the overall distribution of the material on the electronic belt scale. Since the electronic belt scale achieves constant flow feeding within a certain time period, the stacking posture of the material output after weighing is uncertain, which may result in some positions accumulating large amounts of material while others have no material input, hindering the blending and mixing of materials in subsequent processing. Summary of the Invention

[0004] The purpose of this invention is to provide a material thickness uniformity adjustment device to solve the problem that the thickness of the material weighed and output by the electronic belt scale is uncertain, which may result in uneven distribution and affect the subsequent blending and mixing of the material.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A material thickness uniformity adjustment device includes an electronic belt scale, the discharge end of which is provided with a feeding belt, the feeding belt is provided with a material thickness detection unit, and the feeding belt is provided with a material thickness adjustment unit.

[0007] The material thickness adjustment unit includes a material pusher and a rotating shaft. The rotating shaft is rotatably mounted above the feed belt, and the material pusher is disposed on the rotating shaft. The material pusher is used to adjust the thickness of the material layer on the feed belt.

[0008] Preferably, a drive motor is fixedly mounted on the mounting arm on one side of the feed belt, and the output shaft of the drive motor is connected to the rotating shaft. Several material pushers are provided, and these material pushers are arranged circumferentially around the axis of the rotating shaft. This arrangement allows the drive motor to power the rotating shaft, and the multiple material pushers improve the efficiency of adjusting material thickness. When the material thickness is too thick, the upper layer of material is pushed to the rear feed, ensuring uniform material thickness and reducing the possibility of material blockage at the material pushers.

[0009] Preferably, a plurality of adjusting arms are arranged circumferentially around the axis of the rotating shaft, and the material pusher is mounted on the rotating shaft via the adjusting arms. This arrangement allows for adjustment of the material pusher's position on the adjusting arms, facilitating the transport of materials at different thicknesses.

[0010] Preferably, the adjusting arm is provided with a push block height adjusting assembly, the adjusting arm has an installation groove along its length direction, the installation groove passes through the adjusting arm, and the push block height adjusting assembly includes an adjusting rod, the adjusting rod is fixed to one end of the material push block, and the adjusting rod passes through the installation groove;

[0011] The mounting groove has a flared opening on the side away from the adjusting rod. A fixing cap is provided in the mounting groove. The outer wall of the adjusting rod has an external thread, and the fixing cap has an internal thread. The fixing cap and the adjusting rod are connected by threads.

[0012] The front end of the fixing cap is tapered, and the fixing cap contacts the flared opening. This configuration allows the position of the material pusher on the adjusting arm to be changed by the pusher height adjustment component, thereby adjusting the height of the material pushed on the flat surface.

[0013] Preferably, the front sidewall of the material pusher is provided with a guiding slope. This design helps to improve the material pusher's ability to level the material.

[0014] Preferably, the lifting rod is conical, and a dispersing support rod is fixedly connected to the lifting rod. This arrangement helps to further improve the aeration effect between materials.

[0015] Preferably, the material pusher block is equipped with a material agitation component, which includes several lifting rods. These lifting rods are fixed to the lower side wall of the material pusher block along its length. When the material pusher block contacts the material on the feed belt, the lifting rods are positioned below the material pusher block. This arrangement facilitates the dispersing of any compacted material within the feed material using the lifting rods, thus simplifying the subsequent mixing of various materials.

[0016] Preferably, the material pusher includes a mounting base and an elastic part, a connecting spring is provided between the mounting base and the elastic part, and the lifting rod is fixedly connected to the elastic part;

[0017] A telescopic baffle is provided on the front side wall of the elastic part. This design helps to reduce the rigid impact on the feed belt when the lifting rod inserts into the material layer to loosen the material, thus extending the service life of the equipment.

[0018] Preferably, the incoming material thickness detection unit includes a height detector, which is positioned above and directly opposite the feed belt; in the feeding direction of the feed belt, the height detector is located behind the rotating shaft. This configuration facilitates the detection of the material layer thickness on the feed belt using the height detector, and provides an early warning when an abnormal material thickness is detected on the feed belt.

[0019] The invention employing the above technical solution has the following advantages:

[0020] 1. In this solution, by setting up material pushers, the material on the feed belt is fed evenly with a certain thickness under the action of the material pushers for weighing, resulting in good mixing effect in the mixing operation after weighing.

[0021] 2. In this solution, the material pusher block is set on the mounting arm through the pusher block height adjustment component. For different materials, the position of the material pusher block on the adjustment arm is adjusted by the pusher block height adjustment component, which corresponds to different thicknesses of the incoming material, so that the multiple materials are more uniform in the process of blending and mixing, and the blending and mixing effect is improved.

[0022] 3. In this solution, by setting up a foaming component, the lifting rod and dispersing support rod of the foaming component make the materials fluffy, which facilitates mixing and helps improve product quality;

[0023] 4. In this solution, by separating the elastic part of the fixed mounting rod from the mounting base, it is beneficial to reduce the rigid impact on the feed belt when the mounting rod is inserted into the material layer to loosen the material, thus extending the service life of the equipment.

Detailed Implementation

[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0033] like Figures 1-5 As shown, the present invention provides a material thickness uniformity adjustment device, including an electronic belt scale 1, a feeding belt 11 at the discharge end of the electronic belt scale 1, a material thickness detection unit on the feeding belt 11, and a material thickness adjustment unit on the feeding belt 11.

[0034] In this embodiment, a rotating shaft 3 is rotatably mounted above the feed belt 11. A drive motor 4 is fixedly mounted on the mounting arm on one side of the feed belt 11 by screws. The output shaft of the drive motor 4 is connected to the rotating shaft 3 via a coupling. Several sets of adjusting arms 31 are welded circumferentially around the axis of the rotating shaft 3. Preferably, the circumferential interval angle of the adjusting arms 31 is 90 degrees, and there are 4 sets of adjusting arms 31.

[0035] In this embodiment, the material thickness adjustment unit includes a material pusher block 2, of which several blocks are provided. Each material pusher block 2 corresponds to each set of adjusting arms 31. A pusher block height adjustment component is provided on the adjusting arm 31, and the material pusher block 2 is mounted on the adjusting arm 31 via the pusher block height adjustment component. The drive motor 4 rotates in the opposite direction to the feed belt 11. By designing the feeding speed of the feed belt 11 and the rotation speed of the drive motor 4, the drive motor 4 drives the material pusher block 2 to rotate. The lower edge of the material pusher block 2 pushes down any excessively thick material, ensuring a consistent material thickness. This allows the material on the feed belt 11 to be fed evenly at a certain thickness under the action of the material pusher block 2, resulting in good mixing effect in subsequent mixing operations.

[0036] The material pusher block 2 is driven by the drive motor 4 to rotate and flatten the incoming material. When the material thickness is too thick, the upper layer of material is pushed to the rear to make the material thickness uniform and reduce the occurrence of material blockage at the material pusher block 2. In order to improve the material flattening effect, a guide slope 22 is provided on the material pusher block 2.

[0037] In this embodiment, an installation groove 311 is provided along the length of the adjusting arm 31. The front and rear sides of the installation groove 311 penetrate the adjusting arm 31. The push block height adjustment assembly includes an adjusting rod, which is fixed to the material push block 2 and passes through the installation groove 311. A trumpet-shaped opening 3111 is provided on the side of the installation groove 311 away from the adjusting rod 21. An external thread is machined on the adjusting rod 21, and a fixing cap 312 is threadedly connected to the adjusting rod 21. The other end of the fixing cap 312 is inserted into the installation groove 311. An internal thread is machined on the inner wall of the fixing cap 312 to facilitate connection with the adjusting rod 21. The front end of the fixing cap 312 is tapered. The material push block 2 is fixed to the adjusting arm 31 by contacting and pressing the side wall of the fixing cap 312 against the outer wall of the trumpet-shaped opening 3111.

[0038] Understandably, adjustment scales are engraved on one side of the mounting groove 311 of the adjusting arm 31. When the adjusting rod 21 on the adjusting material push block 2 corresponds to different adjustment scales, the thickness of the incoming material on the electronic belt scale 1 is adjusted accordingly. When the thickness of the incoming material needs to be adjusted, first loosen the fixing caps 312 on the adjusting rods 21 at both ends of the material push block 2, then slide it along the length of the mounting groove 311 to the scale corresponding to the material thickness to be adjusted, and then tighten the fixing caps 312 on the adjusting rods 21 to complete the adjustment of the material thickness. The material push block 2 is set on the mounting arm through the push block height adjustment component. During blending, on the electronic scale transporting various materials, the position of the material push block 2 on the adjusting arm 31 is adjusted by the push block height adjustment component to adjust the different thicknesses of the incoming material, making the various materials more uniform during the blending process and improving the blending effect.

[0039] In this embodiment, a material agitation component is provided on the material pusher block 2. The material agitation component includes several lifting rods 5, which are welded to the lower side wall of the material pusher block 2 along the length direction of the material pusher block 2. When the material pusher block 2 rotates and passes above the feed belt 11, the lifting rods 5 are located below the material pusher block 2, which pushes the incoming material on the feed belt 11 and loosens the material layer, making it easier and better to mix the material weighed on the electronic belt scale 1 when it is transported to the next stage for mixing.

[0040] Understandably, to further enhance the agitation and fluffing effect on the material, a dispersing support rod 51 is welded or integrally formed onto the lifting rod 5. When the material pusher 2 rotates with the rotating shaft 3 to flatten an excessively thick layer of incoming material, the lifting rod and the dispersing support rod 51 insert together into the material to agitate the material layer, making the material fluffy and preventing the material from being compacted when the material pusher 2 flattens the material. At the same time, since the rotation direction of the rotating shaft 3 of the drive motor 4 is opposite to the feeding direction of the feeding belt 11, the agitated material will fall to the rear position on the feeding belt 11 to continue transportation without scattering.

[0041] In this embodiment, the material pusher 2 includes a mounting base 201 and an elastic part 202. The material pusher 2 is mounted on the adjusting arm 31 via the mounting base 201. A connecting spring 203 is provided between the mounting base 201 and the elastic part 202. The two ends of the connecting spring 203 are respectively welded to the lower end face of the mounting base 201 and the upper end face of the elastic part 202. The lifting rod 5 is welded or fixedly installed on the lower end face of the elastic part 202 via a threaded connection. When the material pusher 2 rotates with the rotating shaft 3 to flatten the excess material on the feed belt 11, the lifting rod 5 inserts into the material layer to loosen the material. By separating the elastic part 202, which is fixedly installed on the lifting rod 5, from the mounting base 201, it is beneficial to reduce the rigid impact of the lifting rod 5 on the feed belt 11 at this time. When clumps appear in the material layer, the lifting rod 5 and the dispersing support rod 51 can also insert into the clumps and loosen them under the elastic action of the connecting spring 203, resulting in less impact on the feed belt 11 and extending the service life of the equipment.

[0042] When the material pusher 2 drives the lifting rod 5 to insert into the material layer, the elastic part 202 will move upward a certain distance. At this time, a gap will appear between the elastic part 202 and the mounting base 201, and material may enter and accumulate in the gap, causing the connecting spring 203 to fail. Therefore, a telescopic baffle 6 is connected to the front arm of the elastic part 202 by a compression spring. During the movement of the elastic part 202, the telescopic baffle 6 moves synchronously with the elastic part 202, sealing the gap between the elastic part 202 and the mounting base 201, preventing material from entering the gap and accumulating, and extending the service life of the equipment.

[0043] In this embodiment, the incoming material thickness detection unit includes a height detector 12, which is disposed on the feed belt 11, facing the feeding direction of the feed belt 11, and located behind the material pusher block 2. The height detector 12 detects the height of the material layer on the feed belt 11 after adjustment by the material pusher block 2, accurately measuring the thickness of the material layer. An alarm is connected to the height detector 12, and an alarm is triggered when an abnormal material thickness is detected on the feed belt 11, i.e., the material pusher block 2 has not leveled the material.

[0044] Understandably, in other embodiments of this application, due to space limitations, the material thickness adjustment unit may also be positioned above the discharge end of the electronic belt scale.

[0045] The foregoing has provided a detailed description of the material thickness uniformity adjustment device provided by the present invention. The specific embodiments described are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
