Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a screw fixing and packaging mechanism. Background Art

[0002] The screw packaging machine evolved from the food packaging machine. It uses spacing counting and adjusts the frequency of current. The screw packaging machine is a machine that can automatically sort, count, and package regular-shaped products such as screws and nuts. Its functional structure is mainly composed of a hopper, chassis, PLC control system, optical fiber counting system, pneumatic device and other supporting components. After searching, the prior art (publication number: CN220663047U) records "a screw packaging device, relating to the technical field of packaging equipment, including a control body, the top of which is movably connected to an auxiliary transmission mechanism, the top of which is fixedly connected to a working frame, the top of which is fixedly connected to a support frame, the top of which is movably connected to a packaging reel, and both sides of the packaging reel are movably connected to a fixing mechanism. The utility model uses the auxiliary transmission mechanism to drive the movable splint to approach the fixed splint using an electric push rod, so that the movable splint and the fixed splint clamp the packaging bag. The servo motor drives gear 1 to rotate, which drives gear 2 to rotate. Gear 2 drives the electric push rod to rotate, so that the movable splint and the fixed splint clamp the packaging bag and transport it downward. The electric push rod pushes the movable splint to release the packaging bag, and then the servo motor rotates in the opposite direction, driving the electric push rod to rotate and reset, which helps provide support for the packaging bag and prevent it from falling over."

[0003] Although the screw packaging equipment in the existing technology has achieved the support and conveying effects of the packaging bags, there are still some shortcomings: the existing screw packaging equipment lacks the bagging and sealing operations for the screws, resulting in low packaging efficiency. Secondly, there is a certain distance between the auxiliary transmission structure and the packaging reel, resulting in that when the end of the packaging bag is separated from the packaging reel, the end of the packaging bag will fall onto the auxiliary transmission structure and fold, thereby affecting the continued transmission of the auxiliary transmission mechanism.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figures 1 to 4 As shown, the utility model provides a screw-fixed packaging mechanism, comprising: a frame 1, a reel assembly 2 is connected to the inner side of the frame 1, and a conveying assembly 4 is provided on the lower side of the reel assembly 2, and a material guide plate 13 is provided on the lower side of the conveying assembly 4, a vacuum sealer 15 is provided on the lower side of the guide plate 13, and a packaging conveyor belt 16 is provided on the lower side of the vacuum sealer 15, and baffles 161 are arranged at equal distances on the surface of the packaging conveyor belt 16, and an electric control button 17 is provided on the lower side of the packaging conveyor belt 16, and a material discharge assembly 3 is provided on the outer wall of the frame 1, and a material discharge assembly 3 is provided on the lower side. A material guide conveyor belt 14 is provided, and a photoelectric sensor 11 is provided on the upper side of the material guide conveyor belt 14. A discharge hole 12 is opened on the inner wall of the frame 1, and the discharge hole 12 is located on the lower side of the photoelectric sensor 11. At the same time, the discharge hole 12 is located on the upper side of the material guide plate 13, and the material guide conveyor belt 14 is located on the upper side of the discharge hole 12. The conveying assembly 4 includes a fixed frame 41, and the inner side of the fixed frame 41 is rotatably connected to a conveying clamping rod 42, and the outer end of the conveying clamping rod 42 is connected to a gear set 43, and the outer side of the gear set 43 is connected to a motor 44 through a belt and a pulley.

[0022] In this embodiment, the frame 1, the reel assembly 2, the unwinding assembly 3 and the conveying assembly 4 constitute the main structure of the screw-fixed packaging mechanism involved in this application.

[0023] Specifically, during the sealing process, the opening of the packaging bag with screws installed is placed at the sealing position of the vacuum sealer 15, and then the bottom of the packaging bag is placed on the packaging conveyor belt 16. At this time, the baffle 161 on the packaging conveyor belt 16 can be used to apply horizontal moving force to the packaging bag, thereby facilitating the output of the packaging bag to the next process.

[0024] Specifically, the hole wall at the bottom of the feed hole 12 is set to an inclined structure and is inclined downward toward one side of the guide plate 13. The hole wall at the bottom of the feed hole 12 is higher than the upper end surface of the guide plate 13. At the same time, the guide plate 13 is also set to an inclined structure with the bottom downward.

[0025] Specifically, there are multiple groups of electric control buttons 17, which are electrically connected to the material guide conveyor belt 14, the material discharge component 3 and the conveying component 4 respectively, so as to realize manual control of each packaging operation sequence.

[0026] It should be noted that, by setting up the photoelectric sensor 11, when the screws fall from the discharge component 3 to the material guide conveyor belt 14, they are transported for a distance to reach the lower side of the photoelectric sensor, and then electrically connected to the electric push rod 35 mentioned below through the photoelectric sensor 11, so that the electric push rod 35 controls the valve plate 36 to contract and block the screws from being discharged. Then, after one packaging, when the photoelectric sensor 11 detects that there are no screws on the material guide conveyor belt 14, the electric push rod 35 is started again to discharge the material, thereby ensuring that there are always a certain amount of screws on the material guide conveyor belt 14.

[0027] Specifically, the gear 42 is configured as two meshing gears connected to the center shaft end of the conveying clamp 42, and then a pulley is connected to one of the center shaft ends and the outside of the gear, and a pulley is connected to the output shaft end of the motor 44, and a belt is connected between the two pulleys.

[0028] As a preferred embodiment, the conveying clamping roller 42 is used to facilitate the downward conveyance of the continuous packaging bags, and then the packaging bags are torn apart at the breakpoint connection to form independent packaging bags.

[0029] like Figure 1 and Figure 2 In the embodiment, the reel assembly 2 includes a fixed block 25 fixed to the inner wall of the frame 1, and a positioning shaft 24 is connected between the fixed blocks 25, and the outer side of the positioning shaft 24 is rotatably connected to the cylinder 27, the outer side of the positioning shaft 24 is slidably connected to the friction plate 22 and the clamping plate 21, and the clamping plate 21 is connected to the outer side of the friction plate 22, and the friction plate 22 is located at both ends of the cylinder 27, and a spring 26 is provided on the outer side of the clamping plate 21, and a guide rod 23 is slidably connected to the upper end of the clamping plate 21.

[0030] As a preferred embodiment, the clamping plate 21 and the friction plate 22 facilitate friction speed limiting of both ends of the cylinder 27 under the action of the spring 26, so that the packaging bag is driven downward under the pull of the conveying clamping rod 42, and then the cylinder 27 is driven to rotate for transportation.

[0031] It should be noted that the breakpoint lines of the packaging bag are equidistantly arranged on the packaging bag when it is wound on the cylinder 27, and the downward clamping and conveying force of the conveying clamp 42 (which can be pre-adjusted by adjusting the friction gap of the conveying clamp 42 according to the thickness of the packaging bag) is smaller than the tearing force of the breakpoint line, that is, smaller than the force of manual tearing.

[0032] like Figure 1 and Figure 3In the figure, the discharge assembly 3 includes a storage hopper 31, and the lower end of the storage hopper 31 is connected to a discharge pipe 32, and the discharge pipe 32 is fixed to the outer wall of the frame 1 through a mounting frame 34, and the lower end of the discharge pipe 32 is connected to a rubber sleeve 38, the outer wall of the discharge pipe 32 is connected to a vibrator 33, and a valve plate 36 is slidably inserted in the pipeline of the discharge pipe 32, the outer end of the valve plate 36 is connected to a limiting block 37, and the inner end of the valve plate 36 is connected to an electric push rod 35.

[0033] As a preferred embodiment, a rubber sleeve 38 is provided to cushion the falling screws, and the bottom of the rubber sleeve 38 is placed close to the upper end of the guide conveyor belt 14 to prevent the falling screws from hitting the guide conveyor belt 14 and bouncing out.

[0034] During use, the reel assembly is used to facilitate the packaging bag wound on the cylinder, and the friction plate, clamping plate and spring are used to facilitate the speed limit of the rotating cylinder, and then the packaging bag is conveyed downward by the conveying clamping rod included in the conveying assembly, and then the packaging bag is torn off through the broken line gap, and then the conveying assembly is stopped, and then the discharge assembly and the vibrator are used to facilitate the screw to fall onto the guide conveyor belt through the discharge pipe when the valve plate is open, and then it is conveyed to the lower feed port and slides to the inside of the frame through the guide plate. At this time, the packaging bag is opened manually to catch the fallen screw, and then the bag mouth of the packaging bag is vacuum sealed by a vacuum sealer, and then output through the packaging conveyor belt.

[0035] The screw fixing packaging mechanism of the utility model can effectively solve the problems of low packaging efficiency and inconvenient transportation of packaging bags in the screw packaging equipment in the prior art. It improves the efficiency of screw packaging on the basis of the existing screw fixing packaging mechanism technology and facilitates the transportation and sealing of packaging bags.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
