Description

Technical Field

[0001] This utility model relates to the field of automatic conveying equipment technology, specifically a bar stock feeding device. Background Technology

[0002] Chalcogenide glasses are amorphous materials formed based on chalcogen elements (including sulfur, selenium, and tellurium). They have excellent infrared transmittance, low thermo-optic coefficient, good thermal stability and chemical stability, and are considered ideal infrared lens materials. Currently, chalcogenide glass lenses have been widely used in infrared thermal imaging systems, playing an important role in infrared temperature measurement, security monitoring, law enforcement search and rescue, national defense security and other fields.

[0003] The current manufacturing process for chalcogenide glass rods involves first producing large-diameter rods, followed by smaller-diameter rods. To improve precision, the rods are often ground to obtain the specified dimensions. Traditionally, the rods are manually fed to the grinding wheel of a machine. Once the product flows out from the other end of the wheel, the operator catches the rod by hand. This traditional feeding method is clearly time-consuming, labor-intensive, and has a low safety factor. Therefore, automated rod feeding has become crucial for improving production efficiency.

[0004] CN218173642U discloses a round bar feeder, including a frame, a feeding conveyor belt, a distributing conveyor belt, and multiple discharge wheels. The feeding conveyor belt, the distributing conveyor belt, and the discharge wheels are mounted on the frame. The distributing conveyor belt is vertically arranged between the feeding conveyor belt and the discharge wheels. The conveying end of the feeding conveyor belt extends to the distributing conveyor belt. A trough is provided between the feeding conveyor belt and the distributing conveyor belt. The trough extends downward at an incline to the lower part of the distributing conveyor belt. Multiple hooks are provided on the feeding conveyor belt. The feeding conveyor belt is used to convey round bars to the trough. The distributing conveyor belt uses the hooks to pick up the round bars in the trough and convey them to the discharge wheels.

[0005] The aforementioned patent uses a material distribution conveyor belt with hooks to transfer round bars from the feeding conveyor belt. This requires a high degree of mechanical coordination between the feeding conveyor belt and the material distribution conveyor belt, necessitating synchronous rotation of both.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Example 1

[0031] refer to Figures 1-4A bar stock feeding device includes a hopper 1 for placing bar stock a, an output mechanism 3 for conveying bar stock a to the next process, and a transfer mechanism 2 for transferring bar stock a to the output mechanism 3. The bottom of the hopper 1 is provided with a discharge port b that matches the size of bar stock a. The transfer mechanism 2 includes a distribution wheel 21 disposed at the discharge port b and a power module 22 for driving the distribution wheel 21 to rotate. The outer periphery of the distribution wheel 21 is provided with a plurality of U-shaped grooves c that can accommodate bar stock a.

[0032] When the U-shaped groove c rotates to the discharge port b, a bar a is obtained; when the U-shaped groove c rotates to the output mechanism 3, the bar a on it is transferred to the output mechanism 3.

[0033] In practical applications, the staff neatly arranges the bar stock a in the hopper 1, and then drives the device. The distribution wheel 21 starts to rotate, and the bar stock a in the hopper 1 falls from the drop port b into the U-shaped groove c of the distribution wheel 21. Driven by the power module 22, the U-shaped groove c carries the bar stock a to the output mechanism 3 and releases the bar stock a, thereby realizing the transfer.

[0034] In this embodiment, the transfer mechanism 2 obtains bar stock a from the discharge port b of the hopper 1 through the U-shaped groove c on the distribution wheel 21, and then transfers the bar stock a to the output mechanism 3 at intervals under the drive of the power module 22. The entire transfer process is fast and convenient. The staff only needs to put the bar stock a into the hopper 1, which significantly improves the efficiency and safety of the transfer. At the same time, the entire transfer process has little impact on the bar stock a and will not damage the bar stock a, thereby reducing the defect rate of subsequent processes.

[0035] In this embodiment, specifically, the output mechanism 3 includes a receiving plate 31 and a conveying module 32; the receiving plate 31 is arranged at an angle with one end located at the conveying module 32 and the other end located at the material distribution wheel 21, and is used to transfer the bar material a on the U-shaped groove c of the material distribution wheel 21 to the conveying module 32.

[0036] In practical applications, it should be noted that the higher end of the receiving plate 31 should be located in the lower half of the material distribution wheel 21, so that the bar stock a falls onto the receiving plate 31 due to its own weight. In addition, in order to avoid damaging the bar stock a, the tilt angle of the receiving plate 31 should not be too large, preferably less than 30°.

[0037] In this embodiment, more specifically, the transfer mechanism 2 further includes an arc plate 23; the arc plate 23 is disposed on one side of the material distribution wheel 21 and is used to prevent the bar material a on the U-shaped groove c from being thrown out due to rotation.

[0038] In practical applications, the arc plate 23 is set on the upper half of the material distribution wheel 21 to close the U-shaped groove c, so that it will not be thrown out of the material distribution wheel 21 due to rotation, and the bar a is just separated from the material distribution wheel 21 at the receiving plate 31.

[0039] In a preferred embodiment, the power module 22 includes a first motor 221, a driving wheel 222 driven by the first motor 221, and a driven wheel 223 driven by the driving wheel 222; the driven wheel 223 is driven by the material distribution wheel 21. In a further preferred embodiment, the driving wheel 222 and the driven wheel 223 are driven by a synchronous belt 224. Of course, this embodiment does not limit the transmission method of the material distribution wheel 21; other transmission methods used by those skilled in the art to drive the material distribution wheel 21 to rotate should also be within the scope of protection of this embodiment.

[0040] In practical applications, the bottom of the hopper 1 is inclined towards the discharge port b. As a preferred embodiment, the hopper 1 is a right-angled trapezoidal structure that is wider at the top and narrower at the bottom, with the upper end being an open side for workers to replenish the bar stock a; the discharge port b is located on one side of the bottom of the hopper 1.

[0041] Under the above-mentioned preferred conditions, the bar stock a in the hopper 1 can fall one by one from the discharge port b due to its own weight, and the discharge port b set on one side can prevent two bar stock a from blocking the discharge port b.

[0042] In this embodiment, specifically, the conveying module 32 includes a conveyor belt 321 and a second motor 322 for driving the conveyor belt 321. More specifically, the conveyor belt 321 is provided with a baffle 323 for limiting the movement range of the bar stock a.

[0043] In practical applications, a controller 4 is also included; the controller 4 is used to adjust the transfer speed of the bar stock a. In this embodiment, the controller 4 adjusts the rotational speed of the first motor 221 and the second motor 322 to adjust the rotational speed of the bar stock a. As for how to control the rotational speed of the motors, it is a PLC control method familiar to those skilled in the art, and will not be described in detail in this embodiment.

[0044] In this embodiment, specifically, it also includes a frame 5; the output mechanism 3 is mounted on the frame 5; a support base 51 is mounted on the frame 5; and the hopper 1 and the transfer mechanism 2 are mounted on the support base 51. Under the above design, the hopper 1, the transfer mechanism 2, and the output mechanism 3 are arranged from high to low, thereby realizing the transfer of bar stock a.
