Description

Technical Field

[0001] This utility model relates to the field of material dispensing mechanisms, and in particular to automatic material dispensing mechanisms. Background Technology

[0002] In automated production lines for small handicrafts, the directional distribution and conveying of materials are crucial processes. Currently, common material distribution mechanisms often employ fixed, arc-shaped guide strips. Their working principle is as follows: the conveyor belt carries the material forward; when the material comes into contact with the arc-shaped guide strip fixed to one side of the conveyor belt, it is blocked and guided by the strip. Driven by the continuous movement of the conveyor belt, the material is forced to slide along the arc surface of the guide strip and is sequentially guided and diverted to the corresponding processing equipment or workstation entrance.

[0003] When the material conveying speed is high or the material flow is uneven, the material is prone to accumulate in front of the interception point of the guide bar. The accumulated material squeezes and collides with each other, which can easily cause jamming. Once jammed, not only will the production process be interrupted and manual intervention is required to remove it, but more seriously, the material is prone to deformation, scratches or even damage under continuous compression, which directly affects product quality and yield, and reduces production efficiency and equipment utilization. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides an automatic material dispensing mechanism, which can effectively solve the technical problem of easy material accumulation.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The automatic material dispensing mechanism includes a mounting bracket, a drive motor, and a dispensing turntable. The dispensing turntable is horizontally mounted in the mounting bracket. The drive motor is fixedly connected to the mounting bracket, and the rotation shaft of the drive motor is connected to the center point of the top surface of the dispensing turntable. The drive motor drives the dispensing turntable to rotate horizontally around the center point of the dispensing turntable. A material-blocking bar is provided on the bottom surface of the dispensing turntable. The material-blocking bar passes through the center of the dispensing turntable. When the dispensing turntable rotates, it drives the material-blocking bar to move together around the center point of the top surface of the dispensing turntable.

[0007] Furthermore, the material distribution area is provided with a connecting plate, which is located below the material blocking bar. The top surface of the connecting plate does not contact the bottom surface of the material blocking bar, and the connecting plate is provided with a material distribution feed port.

[0008] Furthermore, the connecting plate is semi-circular, and a retaining edge is provided on the arc edge of the connecting plate.

[0009] Furthermore, the material blocking bars are provided in two or more forms, and the two or more material blocking bars divide the bottom surface of the material distribution turntable into two or more material distribution areas.

[0010] Furthermore, two or more material-blocking bars are evenly distributed around the axis of the material distribution turntable, and the length of the material-blocking bars is equal to the radius of the material distribution turntable.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: one half of the material distribution turntable is located above the material conveyor belt, and the other half is located above the equipment conveyor belt area. The drive motor drives the material distribution turntable and its bottom baffle bars to rotate continuously horizontally. When the material on the material conveyor belt reaches the area of ​​the material distribution turntable, the rotating baffle bars continuously and gently push the material from the conveyor belt into the equipment conveyor belt. Because the baffle bars rotate, they can disperse the arriving material in a timely manner, avoiding the material from accumulating at fixed points for a long time and from violently squeezing and colliding with each other. This significantly reduces the risk of deformation, scratches, or damage to the material caused by squeezing and collision, effectively protecting the product's appearance and structural integrity, and improving the production yield.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following is combined with Figures 1-6 The automatic material dispensing mechanism of this utility model is described in detail below:

[0021] The automatic material dispensing mechanism includes a mounting bracket 1, a drive motor 2, and a dispensing turntable 3. The dispensing turntable 3 is horizontally set in the mounting bracket 1. The drive motor 2 is fixedly connected to the mounting bracket 1. The rotation shaft of the drive motor 2 is connected to the center point of the top surface of the dispensing turntable 3. The drive motor 2 drives the dispensing turntable 3 to rotate horizontally with the axis of the dispensing turntable 3 as the rotation point. The bottom surface of the dispensing turntable 3 is provided with a material blocking bar 4. The material blocking bar 4 passes through the center of the dispensing turntable 3. When the dispensing turntable 3 rotates, it drives the material blocking bar 4 to move together with the axis of the top surface of the dispensing turntable 3 as the rotation point.

[0022] Half of the material distribution turntable 3 is located above the material conveyor belt 6, and the other half is located above the area of ​​the equipment conveyor belt 7. The drive motor 2 drives the material distribution turntable 3 and its bottom retaining bar 4 to rotate continuously horizontally. When the material 8 on the material conveyor belt 6 reaches the area of ​​the material distribution turntable 3, the rotating retaining bar 4 continuously and gently pushes the material 8 from the conveyor belt into the equipment conveyor belt 7. Since the retaining bar 4 is rotating, it can promptly disperse the arriving material 8, avoiding the material 8 from accumulating at fixed points for a long time and from violently squeezing and colliding with each other. This significantly reduces the risk of deformation, scratches or damage to the material 8 caused by squeezing and collision, effectively protecting the product's appearance and structural integrity, and improving the production yield.

[0023] The material distribution area 301 is equipped with a connecting plate 5, which is located below the material blocking bar 4. The top surface of the connecting plate 5 does not contact the bottom surface of the material blocking bar 4. The connecting plate 5 provides a smooth transition support surface for the material 8 pushed by the material blocking bar 4 to move to the equipment conveyor belt 7. The connecting plate 5 is equipped with a material distribution feed port 501 to ensure that the material can fall accurately and smoothly into the equipment conveyor belt 7. The connecting plate 5 is semi-circular, and the arc edge of the connecting plate 5 is provided with a retaining edge 502. Its shape is more in line with the rotation path of the material distribution turntable 3 and the movement trajectory of the material blocking bar 4, which can guide the material 8 to flow to the material distribution feed port 501 more naturally and efficiently. The retaining edge 502 set on the arc edge effectively prevents the material 8 from accidentally slipping off the connecting plate 5 when sliding on it, ensuring the reliability of the material distribution process and the integrity of the material.

[0024] Four material blocking bars 4 are evenly distributed around the axis of the material distribution turntable 3. The length of each material blocking bar 4 is equal to the radius of the turntable 3, ensuring that the movement trajectory of each material blocking bar 4 can effectively cover the entire working area from the center to the edge of the turntable. This ensures reliable interception of arriving material 8 on the material conveyor belt 6 side and complete pushing of material to the material distribution feed port 501 on the equipment conveyor belt 7 side. The even distribution guarantees the regularity and stability of the material distribution action, avoiding vibration or uneven force caused by structural asymmetry, resulting in smoother operation. The four material blocking bars 4 divide the bottom surface of the material distribution turntable 3 into four material distribution areas 301. Each rotation of the material distribution turntable 3 completes multiple material distribution actions, significantly improving the material distribution capacity per unit time.

[0025] An automatic material distribution mechanism is installed at the edge of the material conveyor belt 6, and the equipment conveyor belt 7 is located outside the material conveyor belt 6. The automatic material distribution mechanism enables the connection of materials from the conveyor belt to the equipment conveyor belt 7. The material distribution turntable 3 is horizontally set, with about half of its disc surface located above the material conveyor belt 6 and the other half extending above the area of ​​the equipment conveyor belt 7. The connecting plate 5 is installed on the side wall of the material conveyor belt 6, so that the material conveyor belt 6 and the equipment conveyor belt 7 are connected in plane. The material distribution and feeding port 501 on the connecting plate 5 is precisely aligned with the inlet of the equipment conveyor belt 7.

[0026] like Figure 6 As shown, during operation, the material conveyor belt 6 continuously transports material 8. When material 8 travels with the conveyor belt to below the distribution turntable 3, the bottom end of the baffle bar 4 blocks the arriving material 8 in the distribution area 301. The drive motor 2 drives the distribution turntable 3 to rotate horizontally, and the material 8 blocked by the baffle bar 4 in the distribution area 301 is then pushed by the rotating baffle bar 4. Under the push of the baffle bar 4, the material 8 is guided to the surface of the connecting plate 5 located below it. The material 8 slides along the connecting plate 5 and finally falls smoothly and accurately into the aligned equipment conveyor belt 7 at the distribution feed port 501, thus being sent to subsequent production equipment for processing.

[0027] The material distribution turntable 3 has two working modes:

[0028] Mode 1: The material distribution turntable 3 rotates continuously, sweeping the material 8 on the material conveyor belt 6 into the equipment conveyor belt 7.

[0029] Mode 2: The material distribution turntable 3 rotates at intervals, once every 15 seconds, and rotates 90° each time. After the material 8 has accumulated a certain amount in the material distribution area 301, it is then swept into the equipment conveyor belt 7.

[0030] When there is too much material 8 on the equipment conveyor belt 7, the material distribution turntable 3 rotates and passes through the material blocking bar 4 to send the excess material 8 back to the material conveyor belt 6, thus avoiding the pushing and shoving of materials on the equipment conveyor belt 7.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
