Description

Technical Field

[0001] This utility model relates to the field of spool transportation technology, specifically to a material distribution mechanism. Background Technology

[0002] The sequential feeding of yarn bobbins is a crucial link connecting upstream and downstream processes. When it is necessary to intercept a yarn bobbin, the drive unit pushes a stop block into the conveyor channel to block the leading yarn bobbin; after the subsequent station is ready, the stop block retracts and releases the yarn bobbin. However, after the stop block extends to intercept and stops, it must wait for the current yarn bobbin to be processed by the subsequent equipment before it can begin to retract; after the stop block retracts, it must also wait for the next yarn bobbin to move to the predetermined position before it can extend again to intercept. Thus, the stop block has two waiting phases, and the inability to prepare for interception causes periodic interruptions in the conveyor, making the entire process unable to operate continuously. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a material dispensing mechanism to solve the problems of long waiting period and discontinuous process in the material dispensing of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A material distribution mechanism is used to convey yarn bobbins; the material distribution mechanism includes:

[0006] The frame has independently set up conveying and installation areas;

[0007] The material distribution structure includes a first material distribution block and a second material distribution block, which are arranged at intervals.

[0008] The drive structure includes a meshing drive gear and a driven gear, both of which are rotatably disposed in the mounting area and are respectively connected to the first material distribution block and the second material distribution block;

[0009] Under the action of external force, the driving gear and the driven gear rotate in opposite directions, so that the first material distribution block and the second material distribution block alternately extend into the conveying area and intercept or release the yarn bobbin one by one.

[0010] Furthermore, the first material distribution block and / or the second material distribution block includes a connecting part and a stop part connected in sequence. The connecting part is disposed on the driving gear or the driven gear, and the stop part is disposed at an angle to the connecting part for extending into or out of the conveying area.

[0011] Furthermore, the connecting part and / or the connection between the connecting part and the stop part are provided with a notch to avoid the frame.

[0012] Furthermore, the stop portion is provided with an elastic pad.

[0013] Furthermore, the frame is provided with several limiting structures, which are located at the beginning and / or end of the rotation path of the first material distribution block and / or the second material distribution block, and can elastically abut against the stop portion.

[0014] Furthermore, the limiting structure is a spring.

[0015] Furthermore, one end of the spring is disposed on the frame, and the other end is provided with a limit block, which abuts against or separates from the stop portion.

[0016] Furthermore, the limiting block has a limiting end face for adapting to the stop portion.

[0017] Furthermore, the drive structure also includes: a telescopic member and a connecting rod that are rotatably connected, the telescopic member being disposed in the mounting area, and the connecting rod being connected to the drive gear.

[0018] Furthermore, a guide rod is suspended in the conveying area, and the guide rod is arranged along the conveying direction of the conveying area to form a guide channel.

[0019] Compared with the prior art, this utility model has the following beneficial effects: By using a set of opposing rotating drive gears and driven gears, the first and second material distribution blocks alternately and cyclically extend into the conveying area. When the first material distribution block extends out and the second material distribution block extends into the conveying area, the second material distribution block can intercept the current bobbin. When the first material distribution block extends in and the second material distribution block extends out of the conveying area, the current bobbin is released while the first material distribution block can intercept the next bobbin, so as to seamlessly intercept the next bobbin and prepare for the release of the next bobbin, thereby making the conveying process smooth and continuous and reducing waiting time. Furthermore, the alternating cooperation of the first and second material distribution blocks can reduce the impact force on the bobbin, thereby improving the stability of the bobbin during conveying.

[0032] The present invention will be further described in detail below through specific embodiments:

[0033] In the embodiments of this utility model, such as Figure 1 As shown, the material distribution mechanism includes: a frame 1, a material distribution structure, and a drive structure 4; the frame 1 has a conveying area 101 and an installation area 102 that are independently arranged; the material distribution structure includes a first material distribution block 2 and a second material distribution block 3, which are arranged at intervals; the drive structure 4 includes a meshing drive gear 401 and a driven gear 402, both of which are rotatably disposed in the installation area 102 and connected to the first material distribution block 2 and the second material distribution block 3 respectively; wherein, under the action of external force, the drive gear 401 and the driven gear 402 rotate in opposite directions, so that the first material distribution block 2 and the second material distribution block 3 alternately extend into the conveying area 101 and intercept or release the yarn bobbin one by one.

[0034] Specifically, in this embodiment of the invention, a conveyor belt is provided on the frame 1 along a first direction, so that the conveyor belt transports the bobbin along the first direction and forms a conveying area 101 of the frame 1; a mounting base is provided on the frame 1 along a second direction, so that the mounting base is located on one side of the conveyor belt and forms a mounting area 102 of the frame 1. The first and second directions are perpendicular to each other, and the conveyor belt acts as a transport bridge to connect the upper and lower processes. Figure 1 Part of the conveyor belt is omitted; only the conveyor area 101 near the installation area 102 is shown. In other embodiments, the conveyor belt's conveying direction and installation direction can be rationally selected according to the path of the two processes.

[0035] In this embodiment of the invention, two material distribution blocks are provided in the installation area 102, namely, a first material distribution block 2 and a second material distribution block 3, and the two material distribution blocks are arranged at intervals along a first direction, so that the first material distribution block 2 can intercept the bobbins preferentially over the second material distribution block 3. Furthermore, in order to enable one of the two material distribution blocks to perform an interception / release action while the other prepares to intercept, the two material distribution blocks are driven by a drive structure 4 provided in the installation area 102, so that the two material distribution blocks can alternately extend into the conveying area 101 to intercept and release the bobbins one by one.

[0036] Specifically, the drive structure 4 includes a meshing drive gear 401 and a driven gear 402. The drive gear 401 can rotate in both directions by a certain angle under external force, and in conjunction with it, the driven gear 402 rotates in the opposite direction. Simultaneously, the first material distribution block 2 and the second material distribution block 3 are connected to the drive gear 401 and the driven gear 402, respectively. Figure 1 As shown, when the first material distribution block 2 extends into the conveying area 101 and the second material distribution block 3 extends out of the conveying area 101, the first material distribution block 2 performs an interception action, and the second material distribution block 3 performs a release action. When the driving gear 401 rotates clockwise, the first material distribution block 2 gradually extends out of the conveying area 101 and performs a release action; while the driven gear 402 rotates counterclockwise, causing the second material distribution block 3 to gradually extend into the conveying area 101 and intercept the current spool released by the first material distribution block 2. Conversely, when the driving gear 401 rotates counterclockwise, the first material distribution block 2 gradually extends into the conveying area 101 and intercepts the next spool; while when the driven gear 402 rotates clockwise, the second material distribution block 3 gradually extends out of the conveying area 101 and releases the aforementioned current spool. Thus, driven by the first and second gears, the first and second dividing blocks 2 and 3 can alternately and cyclically extend into the conveying area 101 to seamlessly connect to the next yarn bobbin, preparing for its release and making the conveying process smooth and continuous. Furthermore, since the first dividing block 2 can block the yarn bobbin and guide it to the second dividing block 3 during conveying and gear rotation, the impact on the bobbin is reduced compared to a single linear interception method, resulting in smoother and more stable yarn bobbin conveying. Of course, for protection and dust prevention, a housing (not shown) is provided in the mounting area 102 to house the drive structure 4.

[0037] This embodiment achieves continuous material distribution and transportation by alternating the insertion of the first material distribution block 2 and the second material distribution block 3 into the conveying area 101, and has interception preparation, thereby reducing waiting time and improving material distribution and conveying efficiency.

[0038] like Figure 1 , Figure 2As shown, in one embodiment, the first material distribution block 2 and / or the second material distribution block 3 include a connecting portion 201 and a stop portion 202 connected in sequence. The connecting portion 201 is disposed on the driving gear 401 or the driven gear 402, and the stop portion 202 is set at an angle to the connecting portion 201 for extending into or out of the conveying area 101. This embodiment uses the same structure for the first material distribution block 2 and the second material distribution block 3. The following description focuses on the first material distribution block 2. It is understood that the second material distribution block 3 can also have the same structure described below. Specifically, in order to facilitate the material distribution block to extend into or out of the conveying area 101 for interception or release, this embodiment defines the first material distribution block 2 as including the connected connecting portion 201 and the stop portion 202, such that the distal end of the connecting portion 201 is connected to the driving gear 401, and the stop portion 202 can extend into or out of the conveying area 101 to intercept or release the bobbin. Furthermore, since the axis of the drive gear 401 is arranged along a third direction, and any two of the first, second, and third directions are perpendicular to each other, the connecting part 201 and the stop part 202 are arranged at an angle to allow the stop part 202 to enter the conveying area 101. Similarly, to allow the connecting part 201 to connect to the drive gear 401, the connecting part 201 can also have a corresponding bend to adapt to the positions of the mounting area 102 and the conveying area 101. Preferably, a notch 203 is provided at the connection between the connecting part 201 and / or the connection between the connecting part 201 and the stop part 202 to avoid the frame 1.

[0039] like Figure 1 , Figure 2 As shown, in one embodiment, the stop portion 202 is provided with an elastic pad 5. The elastic pad 5 has a certain elasticity, and by replacing the hard contact between the stop portion 202 and the spool with a soft contact, the spool is effectively protected. Furthermore, since the stop portion 202 is suspended, a cantilever structure is formed at this location, and the elastic pad 5 can reduce the impact force of the spool on the stop portion 202. Of course, the size of the elastic pad 5 can be adjusted adaptively, and the elastic pad 5 can be installed at the stop portion 202 by nesting or pasting, which is not limited here.

[0040] like Figure 1As shown, in one embodiment, the frame 1 is provided with several limiting structures. These limiting structures are located at the beginning and / or end of the rotation path of the first material distribution block 2 and / or the second material distribution block 3, and can elastically abut against the stop portion 202. Specifically, to constrain the rotation path of the material distribution blocks, corresponding limiting structures can be provided at the corresponding rotation path of the material distribution blocks; this embodiment uses a limiting structure located at the end of the rotation path of the second material distribution block 3 as an example. When the second material distribution block 3 is in the released position, its stop portion 202 can elastically abut against the limiting structure, thus limiting it to the end of the rotation path. Simultaneously, the elastic abutment method also provides good protection for the stop portion 202. Preferably, the limiting structure is a spring 6.

[0041] Furthermore, such as Figure 3 As shown, in one embodiment, one end of the spring 6 is disposed on the frame 1, and the other end is provided with a limiting block 7, which abuts against or separates from the stop portion 202. Specifically, in order to increase the contact area between the stop portion 202 and the end face of the spring 6, this embodiment provides a limiting block 7 at the end of the spring 6, the cross-sectional area of ​​which is larger than the diameter of the spring 6. Preferably, in order to adapt the limiting block 7 to the outer surface shape of the stop portion 202, not only to form a surface contact between the two, but also to increase the contact area between them, the limiting block 7 has a limiting end face 701 for adapting to the stop portion 202.

[0042] like Figure 1 As shown, in one embodiment, the drive structure 4 further includes a telescopic member 403 and a connecting rod 404 rotatably connected. The telescopic member 403 is disposed in the mounting area 102, and the connecting rod 404 is connected to the drive gear 401. Specifically, in order to drive the drive gear 401 to rotate forward and backward within a certain rotation angle, this embodiment provides a telescopic member 403 in the mounting area 102. The telescopic member 403 can be a linear motion component such as a telescopic rod, a cylinder, or a hydraulic cylinder, and its telescopic end is connected to the drive gear 401 through the connecting rod 404. Thus, when the telescopic member 403 performs reciprocating telescopic motion, it can pull the drive gear 401 to rotate forward and backward through the connecting rod 404, causing the stop portion 202 of the first material distribution block 2 to extend into or out of the conveying area 101, and the driven gear 402 to rotate in the opposite direction, thereby driving the stop portion 202 of the second material distribution block 3 to extend into or out of the conveying area 101.

[0043] like Figure 1As shown, in one embodiment, a guide rod 8 is suspended above the conveying zone 101. The guide rod 8 is arranged along the conveying direction of the conveying zone 101 and forms a guide channel. Specifically, in order to constrain the bobbins within the conveying zone 101 and prevent them from deviating, this embodiment suspends the guide rod 8 above the conveying zone 101. To further constrain the bobbins, two guide rods 8 can be provided, arranged at intervals, with the guide channel formed between them extending along a first direction. The guide rods 8 can then constrain the bobbins at the conveyor belt. Simultaneously, the conveying direction will not change when intercepting and releasing the bobbins. Furthermore, the guide rods 8 are staggered with the material distribution blocks to avoid interfering with the movement of the material distribution blocks.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
