Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a feeding bin for a screw machine. Background Art

[0002] When adding screws to the screw machine silo, the specific model of the screw is determined mainly by scanning the electronic tag on the screw packaging bag. The operator uses a barcode scanner to scan the electronic tag on the screw packaging bag, and the PC receives the scan signal and compares the correlation between the received signal and the internally stored information. If the match is correct, the PLC transmits a signal to the cylinder on the feeder. The cylinder drives the silo cover to move horizontally, unlocking the silo and allowing the operator to pour the screws into the feeder.

[0003] In this solution, the cylinder and the silo cover are fixedly connected. Therefore, when the operator replenishes the screws, it is necessary to ensure that the total amount of the screws does not exceed the opening plane of the silo. Otherwise, when the cylinder drives the silo cover to move horizontally back to its original position, the excess part will conflict with the silo cover, thereby limiting the return of the silo cover. The normal retraction of the cylinder is hindered, which is likely to affect its service life. For this reason, we proposed a screw machine supply silo. Utility Model Content

Specific embodiments

[0022] The following further elaborates the present utility model in combination with the accompanying drawings and embodiments on the above and other technical features and advantages of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them.

[0023] Embodiment:

[0024] As Figures 1 - 4 shown, the present utility model provides a screw machine feeding bin, including a screw machine feeding bin main body 1, a discharge assembly 2 provided on the screw machine feeding bin main body 1, and a screw bin 3 provided on the screw machine feeding bin main body 1. The discharge assembly 2 is communicated with the screw bin 3, and the discharge assembly 2 and the screw bin 3 cooperate to form a screw conveying channel. The screws put into the screw bin 3 are sent out one by one through the discharge assembly 2;

[0025] A cylinder 4 is provided on the side of the screw machine feeding bin main body 1. A connecting plate 5 is installed outside the movable end of the cylinder 4. A position adjusting plate 6 is fixed outside the connecting plate 5. The position adjusting plate 6 is nested and connected to the side of the connecting plate 5. The position adjusting plate 6 is fixed in the connecting plate 5 by friction. The connecting plate 5 provides a lateral connection position adjustment space for the position adjusting plate 6. When the cylinder 4 is in a fully contracted state, the setting mode of the position adjusting plate 6 on the connecting plate 5 can be adjusted by pushing the position adjusting plate 6, so that the position adjusting plate 6 is kept in a setting state aligned with the screw bin 3. A movable connection assembly 7 is provided at the top of the position adjusting plate 6, and a bin shielding assembly 8 is installed on the top of the position adjusting plate 6 through the movable connection assembly 7. The bin shielding assembly 8 completely covers the top of the screw bin 3 under the restriction of the position adjusting plate 6 to completely close the screw bin 3;

[0026] When the sliding return of the bin shielding component 8 is blocked along with the position adjustment plate 6, the bin shielding component slides relative to the position adjustment plate 6 by relying on the movable connection component 7. The bin shielding component 8 is movably connected to the top of the position adjustment plate 6 through the movable connection component 7. The movable connection component 7 includes a chute 71, a connection slider 72, a spring 73, and a connection bolt 74;

[0027] The chute 71 is opened at the middle position of the top of the position adjustment plate 6. The connection slider 72 is arranged in the middle of the chute 71. There are two groups of springs 73. The two groups of springs 73 are respectively arranged on both inner sides of the chute 71. Both ends of the two groups of springs 73 are respectively in contact connection with the outer wall of the connection slider 72 and the inner wall of the chute 71. The connection bolt 74 is threadedly connected inside the connection slider 72. The top end of the connection slider 72 extends to the outside of the chute 71. The connection bolt 74 passes through the bin shielding component 8 and is connected to the connection slider 72. The bin shielding component 8 is held by the connection slider 72 and maintains a certain distance from the top of the position adjustment plate 6, reducing the sliding friction between the bin shielding component 8 and the position adjustment plate 6;

[0028] When the bin shielding component 8 moves back under the drive of the air cylinder 4, the connecting plate 5, the position adjustment plate 6, and the movable connection component 7 and is blocked by the screws exceeding the screw bin 3, the air cylinder 4 continues to drive the connecting plate 5 and the position adjustment plate 6 to move back. The connection slider 72 horizontally moves inside the chute 71 as the bin shielding component 8 is blocked, so that the blocked state of the bin shielding component 8 will not affect the normal retraction of the air cylinder 4. During this process, the spring 73 in contact with the connection slider 72 deforms under force. After the operator levels the screws exceeding the screw bin 3 again, the spring 73 returns to its initial form. Under the elastic force of the spring 73, the connection slider 72 is pushed to the initial position. The bin shielding component 8 connected to the connection slider 72 moves to the initial position synchronously with the connection slider 72 and resumes the shielding effect on the screw bin 3.

[0029] The bin shielding component 8 includes a bin plate 81 and a connection hole 82;

[0030] The end of the bin plate 81 is arranged above the position adjustment plate 6. The connection hole 82 is opened at the middle position of the end of the bin plate 81. The connection bolt 74 passes through the connection hole 82 to fix the chute 71 to the end of the connection slider 72.

[0031] The silo shielding assembly 8 further includes two groups of limit holes 83, which are respectively opened on both sides of the end of the silo plate 81. An embedding bolt 9 is sleeved inside the limit hole 83. Embedding bolt holes 10 matching the limit holes 83 are opened on both sides of the top end of the position adjustment plate 6. The bottom end of the embedding bolt 9 is embedded into the embedding bolt hole 10. Rounding treatments are made at the bottom of the embedding bolt 9 and the top opening of the embedding bolt hole 10. The embedding bolt 9 and the embedding bolt hole 10 cooperate to form an embedded limit structure, which plays an auxiliary role in limiting the relative positions of the silo shielding assembly 8 and the position adjustment plate 6, and ensures the stability of the relative positions between the two under normal conditions. When the silo plate 81 is not hindered by screws, the embedding bolt 9 and the embedding bolt hole 10 cooperate to limit the relative position of the silo plate 81. When the silo plate 81 is hindered by lateral movement, the silo plate 81 moves laterally relative to the position adjustment plate 6, and the embedding bolt 9 moves out of the inside of the embedding bolt hole 10 through friction as the silo plate 81 moves laterally, so that it no longer assists in restricting the lateral movement of the silo plate 81.

[0032] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
