Description

Technical Field

[0001] This utility model relates to the field of glass tempering furnace technology, specifically to a nut feeding mechanism. Background Technology

[0002] Glass tempering furnaces are also commonly referred to as glass tempering equipment, glass tempering units, or tempering furnaces. Glass tempering furnaces use physical or chemical methods to form a compressive stress layer on the surface of the glass and a tensile stress layer inside. When the glass is subjected to external forces, the compressive stress layer can offset some of the tensile stress, preventing the glass from breaking and thus achieving the purpose of improving the strength of the glass.

[0003] Typical thermal insulation cotton has a center hole for installing nuts. Before installing the thermal insulation cotton, the nuts need to be installed into the center hole. Because the nuts are small, the feeding of the nuts is basically done manually, which results in low feeding efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is how to improve the feeding efficiency of nuts.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A nut feeding mechanism includes a feeding base, a pushing cylinder, a pushing rod, a pushing block, and a storage bin. The pushing cylinder is fixed on the feeding base, and the output end of the pushing cylinder is connected to a pushing rod that can slide on the feeding base. Multiple sets of pushing blocks are provided on the pushing rod. A receiving step is provided at the end of the pushing block away from the pushing rod. A storage bin that runs vertically through each set of pushing blocks is provided above it. The bottom of the storage bin is in contact with the top surface of the pushing block, and the bottom of the storage bin has an opening facing the nut feeding direction.

[0007] The bottom set of bolts in the storage bin automatically falls onto the receiving step. The pushing cylinder pushes the pushing block forward, pushing the nuts adsorbed on the receiving step and sending them directly above the center hole of the insulation cotton. This replaces the existing manual nut feeding operation and greatly improves the nut feeding efficiency.

[0008] Preferably, the bottom of the push rod is slidably mounted on the feeding base via a feeding sliding assembly. The feeding sliding assembly includes a linear bearing and a guide rod. Two sets of linear bearings are respectively arranged on the feeding base on both sides of the push cylinder along the conveying direction of the push cylinder. Each set of linear bearings 61 is provided with a guide rod. The bottom of the push rod is slidably mounted on the guide rod via a slider.

[0009] Preferably, the distance between the bottom surface of the receiving step and the top surface of the opening at the bottom of the storage bin is greater than the thickness of one nut and less than the thickness of two nuts.

[0010] Preferably, the sidewall of the receiving step is provided with a concave shape that matches the nut.

[0011] Preferably, the feeding base is further provided with a feeding bottom plate, and the feeding bottom plate is provided with guide grooves corresponding to the number and position of the pushing blocks.

[0012] Preferably, the pushing cylinder is a double-rod cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The bottom set of bolts in the storage bin automatically falls onto the receiving step. The pushing cylinder pushes the pushing block forward, pushing the nuts adsorbed on the receiving step and sending them directly above the center hole of the insulation cotton. This replaces the existing manual nut feeding operation and greatly improves the nut feeding efficiency. Attached Figure Description

[0017] To facilitate understanding of the technical solution of this utility model by those skilled in the art, the technical solution of this utility model will now be further described in conjunction with the accompanying drawings.

[0018] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0019] In this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically limited.

[0020] See Figure 1 and Figure 2This embodiment discloses a nut feeding mechanism including a feeding base 1, a pushing cylinder 2, a pushing rod 3, a pushing block 4, and a storage bin 5. The pushing cylinder 2 is fixed on the feeding base 1. In this embodiment, the pushing cylinder 2 is a double-rod cylinder. The output end of the pushing cylinder 2 is connected to a pushing rod 3 that can slide on the feeding base 1. Four sets of pushing blocks 4 are provided on the pushing rod 3. The end of the pushing block 4 away from the pushing rod 3 is provided with a receiving step 41 for receiving the nut. A vertically penetrating storage bin 5 is provided above each set of pushing blocks 4 for storing the nut. The bottom of the storage bin 5 is in contact with the top surface of the pushing block 4. The bottom of the storage bin 5 has an opening 51 facing the nut conveying direction. The distance between the bottom surface of the receiving step 41 and the top surface of the opening 51 at the bottom of the storage bin 5 is greater than the thickness of one nut and less than the thickness of two nuts, ensuring that when the receiving step 41 moves, it can only take away one nut, while the other nut is in contact with the top surface of the pushing block 4.

[0021] In this embodiment, the nut is a hexagonal nut, the height difference of the receiving step 41 is about 1 / 2 of the nut thickness, the side wall of the receiving step 41 is provided with an inward concave shape that matches the nut, and the pusher block 4 is also weakly magnetic to prevent the nut from rotating during the pushing process.

[0022] The bottom of the push rod 3 is slidably mounted on the feeding base 1 via the feeding sliding assembly 6. The feeding sliding assembly 6 includes a linear bearing 61 and a guide rod 62. Two sets of linear bearings 61 are respectively arranged on the feeding base 1 on both sides of the push cylinder 2 along the conveying direction of the push cylinder 2. Each set of linear bearings 61 is provided with a guide rod 62. The bottom of the push rod 3 is slidably mounted on the guide rod 62 via a slider, driving the push cylinder 2 and causing the push rod 3 to slide on the guide rod 62.

[0023] Furthermore, the feeding base 1 is also provided with a feeding base plate 7, and the feeding base plate 7 is provided with a guide groove 71 corresponding to the number and position of the pusher blocks 4, so that the pusher blocks 4 slide in the guide groove 71, which plays a role in feeding and guiding.

[0024] Furthermore, the bottom surface of the pusher block 4 is higher than the top surface of the insulation cotton, ensuring that the pusher block 4 can push the nut directly above the center hole of the insulation cotton.

[0025] The working principle of this embodiment is as follows: When feeding is required, the pusher cylinder 2 is activated, which drives the pusher rod 3 to push the pusher block 4 forward. The bottom set of bolts of the storage bin 5 falls onto the receiving step 41. The pusher block 4 moves forward and pushes out the nut that is adsorbed on the receiving step 41. When the cylinder reaches the limit position, the nut is fed to the center hole of the insulation cotton.

[0026] In this embodiment, a set of bolts at the bottom of the storage bin 5 automatically falls onto the receiving step 41. The pushing cylinder 2 pushes the pushing block 4, which pushes the nuts adsorbed on the receiving step 41 and sends them directly above the center hole of the insulation cotton. This replaces the existing manual nut feeding operation and greatly improves the nut feeding efficiency.

[0027] 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, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] The above-described embodiments are merely examples of implementation methods of the utility model. The scope of protection of this utility model is not limited to the above-described embodiments. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the scope of protection of this utility model.
