A first fixed frame 201 is provided on one side of the surface of the rack 101, and a second fixed frame 202 is symmetrically arranged on one side of the first fixed frame 201, and the front ends of the outer walls of the first fixed frame 201 and the second fixed frame 202 are fixedly connected with a U-shaped plate 201a; the weighing component 3 includes a connecting plate 301 fixedly connected to the bottom of the placement rack 101, and a weight sensor 302 installed in the middle of the surface of the connecting plate 301, the front end of the upper surface of the connecting plate 301 is movably connected to the bottom of the weighing box 303 through a hinge, the rear end face of the weighing box 303 is movably connected to the telescopic end of the second electric push rod 304 through a hinge, and the bottom end of the second electric push rod 304 is installed on the surface of the connecting plate 301.

[0034] Specifically, a packaging bag conveying mechanism 102 is provided on the top of the front end face of the machine body 1, a discharge pipe 103 is installed in the middle of the front end face of the machine body 1, and back sealing mechanisms 104 are provided on both sides of the discharge pipe 103. A first electric push rod 107 is installed in the middle of the front end face of the mounting frame 105, and the telescopic end of the first electric push rod 107 passes through the through hole on the front end face of the mounting frame 105 and is connected to the outer wall of the movable seat 108. A second hot melt seat 108a is installed in the middle of the inner wall of the movable seat 108, and a blade 108b is installed in the middle of the inner wall of the second hot melt seat 108a. A motor 203 is installed, and a driving wheel 203a is installed on the output shaft of the motor 203. The outer wall of the driving wheel 203a is connected to the outer wall of the driven wheel 204 through a belt. A driving roller 205 is installed on the inner wall of the driven wheel 204. A chain plate 207 is sleeved on the outer side of the outer wall of the driving roller 205. An auxiliary roller 206 is installed on the other side of the chain plate 207. The driving roller 205 and the auxiliary roller 206 are both located between the first fixed frame 201 and the second fixed frame 202. Mounting seats 208 are evenly spaced on the outer wall of the chain plate 207, and a magnetic column 208a is installed in the middle of the outer wall of the mounting seat 208.

[0035] Furthermore, an opening 101a is provided to facilitate the transportation of screws. Two U-shaped plates 201a are provided. When the two U-shaped plates 201a are used together, a gap will be generated between the two, which can block the screws without affecting the movement of the magnetic column 208a. The weight sensor 302 is electrically connected to the external control device. This is a prior art, so it will not be described in detail here. The second electric push rod 304 can push the weighing box 303 to tilt and pour the screws inside it into the discharge pipe 103. The packaging bag conveying mechanism 102, the body 1, the discharge pipe 103, the back sealing mechanism 104, etc. are all prior art, so they will not be described in detail here. The first electric push rod 107 can drive the movable seat 108 to move and make the first hot melt seat 106a and the second hot melt seat 108a contact to achieve the purpose of sealing the packaging bag. This sealing principle is a prior art, so it will not be described in detail here. The outer walls of the driving wheel 203a and the driven wheel 204 are connected by a belt to play a transmission role.

[0036] The operation process of this embodiment is as follows: after the screws are produced, they generally need to be packaged into individual packaging bags, and the screws are placed inside the placement rack 101, and then the motor 203 is started. The output shaft of the motor 203 rotates to drive the driving wheel 203a to rotate, and the outer wall of the driving wheel 203a is connected to the outer wall of the driven wheel 204 through a belt. Therefore, when the driving wheel 203a rotates, it drives the driven wheel 204 to rotate, and makes the driving roller 205 at the inner end of the driven wheel 204 rotate, and under the cooperation of the auxiliary roller 206, it can drive the chain plate 207 to rotate, so that the multiple mounting seats 208 and magnetic columns 208a on the outer wall of the chain plate 207 move in sequence, wherein the magnetic column 208a at the lowest end generates magnetic attraction with the screws during the movement and adsorbs them together (a single magnetic column 208a It only has the magnetic force to absorb a single screw). After the screw is absorbed, it will continue to move with the chain plate 207, and after the absorbed screw moves between the U-shaped plates 201a on both sides, it will be forced to fall into the weighing box below under the limiting action of the U-shaped plate 201a. The number of screws inside the weighing box will be transmitted to the external controller with the action of the weight sensor 302. After the weighing box reaches the preset type, the second electric push rod 304 runs to push the weighing box to tilt, so that the screws inside it fall into the discharge pipe 103 and fall into the packaging bag along the discharge pipe 103. The packaging bag can then be sealed and cut. The number of screws packaged can be accurately controlled without manual sorting and control of the number of packaged screws, which can reduce the labor intensity of the staff, save time and effort, and have high work efficiency.

[0037] Example 2

[0038] See also Figure 5 and Figure 7 Based on Example 1, what is different from the first embodiment is that: a protective frame 109 and a protective component 4 are provided. The protective component 4 includes a movable frame 401 that is sleeved on the outside of the first hot melt seat 106a. Telescopic rods 402 are installed in a horizontal array on the top and bottom of the rear end surface of the movable frame 401, which solves the problem that the existing screw packaging machine lacks protective measures for the heating and sealing components of the packaging bag during use, and workers may be burned if they accidentally touch it, which poses a safety hazard.

[0039] Specifically, a spring 403 is sleeved on the outer side of the outer wall of the telescopic rod 402 , and the telescopic rod 402 and the spring 403 are both located between the moving frame 401 and the fixed seat 106 .

[0040] Furthermore, the telescopic rod 402 serves to limit both the moving frame 401 and the spring 403 , and can drive the moving frame 401 to move under the elasticity of the spring 403 .

[0041] The operation process of this embodiment is as follows: during the screw sorting and weighing process, the packaging bag conveying mechanism 102 will continuously convey the required packaging bags, and after the packaging bags are conveyed to the outer wall of the discharge pipe 103, the flat packaging bags are first sealed into a cylindrical shape under the action of the back sealing mechanism 104, and then the first electric push rod 107 pushes the movable seat 108 to move along the guide rod 105a, so that the second hot melt seat 108a and the first hot melt seat 106a on the fixed seat 106 cooperate to heat-seal the bottom and top ports of the upper and lower packaging bags, and in the heat-sealing process, the upper and lower packaging bags can be cut and separated under the action of the blade 108b, wherein, during the movement of the movable seat 108, the outer side of the second hot melt seat 108a The protective frame 109 will squeeze the movable frame 401 outside the first hot melt seat 106a, and the movable frame 401 will squeeze the telescopic rod 402 and the spring 403 under the force, so that the first hot melt seat 106a and the second hot melt seat 108a can contact and seal the packaging bag. After the movable seat 108 moves outward, the movable frame 401 can be popped outward under the elastic performance of the spring 403, and the movable frame 401 can be sleeved on the outside of the first hot melt seat 106a to play a protective role. At the same time, the protective frame 109 can also cover the first hot melt seat 106a inside to prevent the staff from accidentally touching the heating component or the blade 108b, etc., causing injury to the staff, thereby improving safety.
