Technical Field

[0001] This utility model relates to the technical field of screw packaging, specifically to a lower material support structure for a hardware screw packaging machine. Background Technology

[0002] As is well known, screw packaging machines are machines that can automatically sort, count, and package products with regular shapes such as screws and nuts. Their functional structure mainly consists of a hopper, chassis, PLC control system, fiber optic counting system, pneumatic device, and other supporting components. They are accurate in counting and are gradually being widely used in industries such as hardware, furniture, counting machines, toys, and pharmaceuticals, meeting the requirements of various industries. The lower material support structure is used to receive and guide the packaged screws into the packaging box.

[0003] In existing hardware screw packaging machines, the unloading device causes packaged screws to fall onto the tray one after another during use, resulting in easy accumulation and disorder. Furthermore, the direction of the falling screws cannot be flexibly adjusted. Therefore, a new unloading structure for hardware screw packaging machines is needed. Utility Model Content

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

[0014] 1.

A bearing column 13 is fixedly installed at the lower end of the material distribution mechanism 12, and a control switch 14 is fixedly installed at the front side of the material distribution mechanism 12. The material distribution mechanism 12 includes a three-way material distribution box 1201, a discharge channel one 1202, a discharge channel two 1203, a drop channel 1204, a movable shaft 1205, a guide plate 1206, a fixed plate 1207, a mounting groove 1208, a cylinder 1209, a clamping seat 1210, a pull rod 1211, and a sleeve shaft two 1212. The discharge channel one 1202 is provided on the left side of the three-way material distribution box 1201, and the discharge channel two 1203 is provided on the right side of the three-way material distribution box 1201. The upper end is provided with a material discharge channel 1204. A movable shaft 1205 is provided inside the three-way material distribution box 1201. A guide plate 1206 is fixedly connected to the outer side of the movable shaft 1205. A fixing plate 1207 is fixedly installed on the rear side of the three-way material distribution box 1201.

The pull rod 1211 is away from the clamping seat 1210. One end is fixedly installed with a sleeve shaft 1212. With the setting of the material distribution mechanism 12, when the screw pack falls from the discharge port 11, the cylinder 1209 drives the clamping seat 1210, the pull rod 1211 and the sleeve shaft 1212 to rotate, thereby causing the movable shaft 1205 and the guide plate 1206 to rotate, thereby controlling the falling direction of the screw pack, so that it can be discharged from the discharge channel 1202 or the discharge channel 2203.

[0025] See also Figure 2-6In this embodiment, the support column 2 is fixedly installed between the bracket 1 and the material tray 3. The material tray 3 has a circular structure. Four partitions 10 are fixedly connected to the outer side of the sleeve shaft 9. The partitions 10 are arranged in a cross-shaped symmetrical distribution on the outer side of the sleeve shaft 9. Through the cooperation of the drive motor 4, pulley 5, belt 6, pulley 7, and rotating shaft 8, the sleeve shaft 9 and partitions 10 fixed on the outer side of the rotating shaft 8 can be driven to rotate. This continuously pushes the screw packs falling from the material tray 3 into the discharge port 11, realizing continuous and orderly material conveying. Compared with the traditional method of relying on gravity to fall naturally, it can better control the discharge speed and flow rate, avoiding the reduction in packaging efficiency caused by material accumulation or blockage. It can be adjusted according to the packaging requirements. The overall production speed of the machine is adjusted to regulate the motor speed, match the working rhythm of the equipment, and ensure the efficient operation of the entire packaging production line. The material discharge port 11 is adapted to the material discharge channel 1204. The first discharge channel 1202 and the second discharge channel 1203 are symmetrically distributed. The movable shaft 1205 passes through the three-way material distribution box 1201 and is fixedly installed with the second sleeve shaft 1212. The cylinder 1209 is adapted to the mounting groove 1208. The guide plate 1206 and the pull rod 1211 are aligned. There are two bearing columns 13 located at the middle of the lower end of the three-way material distribution box 1201. The drive motor 4 and the cylinder 1209 are electrically connected to the control switch 14. The guide plate 1206 is adapted to the diameter of the first discharge channel 1202 and the second discharge channel 1203.

[0026] Working Principle: After the packaged screws fall onto the material tray 3, the drive motor 4, pulley 5, belt 6, pulley 7, and rotating shaft 8 work together to drive the outer fixed sleeve 9 and partition 10 of the rotating shaft 8 to rotate. This continuously pushes the screw packages falling from the material tray 3 into the discharge port 11, achieving continuous and orderly material conveying. Compared with the traditional method of relying on gravity to fall naturally, this method can better control the discharge speed and flow rate, avoiding the reduction in packaging efficiency caused by material accumulation or blockage. The motor speed can be adjusted according to the overall production speed of the packaging machine to match the working rhythm of the equipment and ensure the overall efficiency. The efficient operation of the packaging production line is achieved through the setting of the material distribution mechanism 12. When the screw pack falls from the discharge port 11, the cylinder 1209 drives the clamping seat 1210, the pull rod 1211 and the sleeve shaft 1212 to rotate, thereby rotating the movable shaft 1205 and the guide plate 1206. This controls the direction of the screw pack's fall, allowing it to be discharged from the discharge channel 1202 or the discharge channel 2 1203. This facilitates single-channel or dual-channel packaging, avoids downtime due to changing packaging boxes, improves the continuity and efficiency of packaging, and allows for flexible adjustment when packaged screws need to be repackaged into different packaging boxes.
