Description

Technical Field

[0001] This invention belongs to the field of packaging machine technology, and specifically relates to a packaging machine. Background Technology

[0002] In product packaging lines, automated equipment has become the mainstream packaging equipment. The packaging process usually takes two forms: one is to transport the materials to be packaged to the corresponding packaging bags or boxes at the corresponding workstation via a conveyor belt, and then carry out the packaging operation; the other is to first transport the materials to be packaged to the corresponding feeding mechanism via a conveyor belt, and then the feeding mechanism pushes the workpiece into the packaging bag or box, and then completes the packaging.

[0003] However, the packaging operation of existing packaging bags is relatively difficult. When using packaging bags, the bags need to be fully opened to smoothly place the materials to be packaged. For some products (such as televisions), packaging also involves small parts and materials such as instruction manuals, remote controls, and data cables. However, existing technologies often fail to effectively open the packaging bags, failing to ensure that the feeding mechanism can smoothly feed the materials into the bag, and frequently resulting in the feeding mechanism pulling the workpiece out again when it retracts, thus affecting packaging efficiency. Therefore, improvements to existing technologies are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a packaging machine to solve the aforementioned problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A packaging machine includes an infeed conveyor and an outfeed conveyor.

The bag-supporting bracket is equipped with an upper suction nozzle assembly, a bag-supporting assembly, and a lower pressing assembly. The upper suction nozzle assembly sequentially sucks up the upper layer of the packaging bag, and the bag-supporting assembly opens the bag opening. When the feeding mechanism pushes the material to be packaged into the packaging bag and is about to exit the packaging bag, the lower pressing assembly presses down on the upper layer of the packaging bag to hold the material to be packaged inside the packaging bag.

A sliding plate that can move towards or away from the discharge conveyor is slidably connected to the bag-supporting bracket. A bag-supporting drive assembly is installed on the sliding plate that can drive the left and right bag-supporting assemblies to move towards or away from each other. The bag-supporting drive assembly controls the left and right bag-supporting assemblies, which are inserted into the bag opening at one end, to move away from each other and open the bag opening. The sliding plate is also connected to a second drive component that can drive it to move towards or away from the discharge conveyor. The second drive component controls the left and right bag-supporting assemblies to move towards or away from the bag opening. The pressing assembly includes a flexible pressing member and a third driving member.

Two sliders each have a first clamping block fixed to the inner side of the bag support belt. Each of the two first clamping blocks is bolted to a second clamping block located on the outer side of the bag support belt. The first clamping blocks and their corresponding second clamping blocks cooperate to clamp the bag support belt. A first contact switch is installed on one side of the slide plate. A first contact block is installed on the second clamping block located on the same side as the first contact switch. As the second clamping block moves, the upper part of the first contact block can contact and trigger the first contact switch.

[0009] As a preferred technical solution of the present invention, the bag support bracket includes two parallel vertical plates, and a second guide rail is installed at the upper end of each of the two vertical plates. The extension direction of the second guide rail is perpendicular to the conveying direction of the conveyor belt. The two ends of the slide plate are slidably connected to the two second guide rails respectively. A second extension frame is fixed on the side of the feeding conveyor away from the conveyor belt. A second driving component is installed on the second extension frame. The second driving component is a cylinder, hydraulic cylinder or electric cylinder. A push plate is installed on the telescopic rod of the second driving component. The push plate is connected to the slide plate.

[0010] In a preferred embodiment of the present invention, the feeding mechanism includes a fixed frame, a feeding plate, and an electric conveying guide rail. The electric conveying guide rail is mounted on the fixed frame, and the feeding plate is positioned below the electric conveying guide rail. The electric conveying guide rail includes an integrated plate, a conveying guide rail, a conveying slider, and a motor drive assembly. The integrated plate is mounted on the fixed frame, the conveying guide rail is positioned on the bottom surface of the integrated plate, the conveying slider is slidably connected to the conveying guide rail, and the motor drive assembly is mounted on the integrated plate and connected to the conveying slider to drive the conveying slider to reciprocate along the conveying guide rail. One end of the feeding plate is fixed with an upwardly extending connecting plate, the upper end of which is connected to the conveying slider.

[0011] As a preferred technical solution of the present invention, the motor drive assembly includes a conveying motor, a first pulley, a second pulley, and an annular belt. The first pulley and the second pulley are rotatably connected to both ends of the bottom surface of the integrated plate, and the two ends of the annular belt are respectively wound around the first pulley and the second pulley. The conveying guide rail is located between the first pulley and the second pulley inside the annular belt, and the conveying slider is connected to the annular belt on one side of the conveying guide rail. The conveying motor is mounted on the top of the integrated plate, and the motor shaft of the conveying motor is coaxially connected to the first pulley. Two clamping plates are clamped on the annular belt on one side of the conveying guide rail. The two clamping plates are respectively disposed on both sides of the annular belt, and the two clamping plates are detachably connected by bolts. One of the clamping plates is connected to the conveying slider.

[0012] In a preferred embodiment of the present invention, the upper end of the integrated plate is connected to an inverted U-shaped guide frame, and a guide plate is provided on the top of the fixed frame. One end of the guide plate is sleeved inside the inverted U-shaped guide frame. A spacing adjustment guide rail is provided on the top surface of the guide plate. The extension direction of the spacing adjustment guide rail is perpendicular to the extension direction of the conveying guide rail. A spacing adjustment slider is fixed inside the inverted U-shaped guide frame and is slidably connected to the spacing adjustment guide rail. A spacing adjustment assembly is installed between the inverted U-shaped guide frame and the guide plate to control the movement of the inverted U-shaped guide frame along the spacing adjustment guide rail. The spacing adjustment assembly includes two fixed blocks that are parallel to each other and fixed on the guide plate. An adjustment screw is rotatably connected between the two fixed blocks. The middle part of the adjustment screw is threadedly connected to the inverted U-shaped guide frame. One end of the adjustment screw passes through a fixed block and is provided with a handwheel.

[0013] As a preferred technical solution of the present invention, two second contact switches for controlling the power supply of the motor drive component are installed on one side of the integrated plate, and a second contact block is provided between the two second contact switches. The lower end of the second contact block is connected to another fixed block. A long strip positioning groove extending along its length is installed on one side of the integrated plate, and each of the two second contact switches is installed on an adjusting block, which is slidably connected to the long strip positioning groove.

[0014] As a preferred technical solution of the present invention, it further includes a feeding mechanism and a sealing mechanism. The feeding mechanism is installed on both sides of the input end of the feeding conveyor, and the sealing mechanism is installed on the side of the discharge conveyor between the bag supporting mechanism and the output end of the discharge conveyor.

[0015] Beneficial effects: In the packaging process, the present invention utilizes a feeding conveyor to transport the materials to be packaged to a feeding mechanism. The materials to be packaged are placed together on the feeding conveyor and then transported together to the feeding mechanism. Meanwhile, the packaging bag moves on the discharging conveyor to the position of the bag-opening mechanism. The bag-opening mechanism first controls the opening of the packaging bag to open it, and then the feeding mechanism delivers the materials to be packaged into the packaging bag. When the feeding mechanism exits the packaging bag, the bag-opening mechanism can also cooperate to press down the materials to be packaged inside the packaging bag, so that the feeding mechanism does not take out the materials to be packaged inside the packaging bag when it exits the packaging bag, thereby achieving smooth bagging of the materials to be packaged and ensuring the final packaging efficiency. Specifically, the bag-supporting mechanism uses an upper suction nozzle to hold the upper layer of the packaging bag and move it upwards, causing the bag opening to open. Then, the left and right bag-supporting components further expand the bag opening, ensuring that the opening is large enough for the feeding mechanism to smoothly transfer the packaging material into the bag. Finally, a flexible pressing component holds the packaging material inside the bag down, preventing the feeding mechanism from pulling out the packaging material when exiting the bag. This method is simple and effective. Attached Figure Description

Detailed Implementation

[0018] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0019] Example: like Figure 1 , Figure 2 As shown, this embodiment provides a packaging machine, including an infeed conveyor 1 and an outfeed conveyor 2. The output end of the outfeed conveyor 2 is provided with a feeding mechanism 3, which is used to convey the material to be packaged to the feeding mechanism 3 through the infeed conveyor 1. Then, the feeding mechanism 3 pushes the material to be packaged into the packaging bag on the outfeed conveyor 2. The feeding mechanism 3 feeds the material to be packaged into the packaging bag on the outfeed conveyor 2 in one go. Then, the bag is sealed manually or by a sealing mechanism 6 to realize the packaging of the material.

[0020] Furthermore, the present invention also includes a bag-supporting mechanism 4, such as Figure 3 , Figure 4 and Figure 5As shown, the bag-supporting mechanism 4 includes a bag-supporting bracket 401 disposed between the feeding mechanism 3 and the discharge conveyor 2. This bracket facilitates the installation of bag-supporting components. Specifically, the bag-supporting bracket 401 is equipped with an upper suction nozzle assembly, a bag-supporting assembly, and a lower pressing assembly. When the packaging bag from the discharge conveyor 2 passes the position of the bag-supporting bracket 401, the upper suction nozzle assembly sequentially sucks up the upper layer of the packaging bag. Then, one end of the bag-supporting assembly is inserted into the bag opening, thus opening the bag to ensure it is large enough. This allows the feeding mechanism 3 to stably push the material to be packaged into the packaging bag. The feeding mechanism 3 can be controlled to transfer the packaging material into the packaging bag. When the feeding mechanism 3 pushes the packaging material into the packaging bag and is about to exit the packaging bag, the pressing component first presses down on the packaging material inside the packaging bag from the top layer. Of course, the pressing component preferably uses a flexible material to press down without applying too much force, just enough to ensure the stability of the packaging material inside the packaging bag. After the pressing component presses down on the packaging material inside the packaging bag, the feeding mechanism 3 can be controlled to exit the packaging bag. Then, the upper suction nozzle component, the bag support component, and the pressing component all detach from the packaging bag, and the subsequent sealing and boxing operations of the packaging bag can be carried out.

[0021] Specifically, the upper suction nozzle assembly includes an upper suction nozzle 402 and a first driving member 403. The first driving member 403 is fixed on the bag support bracket 401 and is connected to the upper suction nozzle 402. The first driving member 403 drives the upper suction nozzle 402 to move up and down. The upper suction nozzle 402 is connected to a vacuum pump. After the first driving member 403 controls the upper suction nozzle 402 to suck down and hold the upper layer of the packaging bag, it controls the upper suction nozzle 402 to move up, causing the upper layer of the packaging bag to detach from its lower layer, thereby opening the bag opening.

[0022] Furthermore, the bag-supporting assembly includes a left bag-supporting assembly and a right bag-supporting assembly. A slide plate 404, which can move towards or away from the discharge conveyor 2, is slidably connected to the bag-supporting bracket 401. A bag-supporting drive assembly is installed on the slide plate 404, which can drive the left and right bag-supporting assemblies to move towards or away from each other. After the bag opening of the packaging bag is opened, the slide plate 404 slides towards the discharge conveyor 2, so that one end of the left and right bag-supporting assemblies enters the bag opening of the packaging bag. Then, the bag-supporting drive assembly starts to operate, which controls the left and right bag-supporting assemblies, which have one end inserted into the bag opening of the packaging bag, to move away from each other and open the bag opening of the packaging bag. The slide plate 404 is also connected to a second drive member 405, which can drive it to move towards or away from the discharge conveyor 2, which controls the left and right bag-supporting assemblies to move towards or away from the bag opening of the packaging bag, thereby adjusting the distance between the left and right bag-supporting assemblies and the packaging bag.

[0023] Furthermore, the pressing assembly includes a flexible pressing member 406 and a third driving member 407. The third driving member 407 is fixed on the bag support bracket 401 and is connected to the flexible pressing member 406. The third driving member 407 drives the flexible pressing member 406 to move up and down. Before the feeding mechanism 3 exits the bag opening, the third driving member 407 drives the flexible pressing member 406 to move down and press down on the material to be packaged inside the bag, ensuring that the material to be packaged will not move out of the bag with the feeding mechanism 3, thereby facilitating the subsequent sealing of the bag.

[0024] In this invention, during packaging, the feeding conveyor 1 transports the materials to be packaged to the feeding mechanism 3. The materials to be packaged are placed together on the feeding conveyor 1 and then transported together to the feeding mechanism 3. Meanwhile, the packaging bag moves on the discharging conveyor 2 to the position of the bag-opening mechanism 4. The bag-opening mechanism 4 first controls the opening of the packaging bag to open, and then the feeding mechanism 3 feeds the materials to be packaged into the packaging bag. When the feeding mechanism 3 exits the packaging bag, the bag-opening mechanism 4 can also cooperate to press down the materials to be packaged inside the packaging bag, so that the feeding mechanism 3 does not bring out the materials to be packaged inside the packaging bag when it exits the packaging bag, thereby realizing the smooth bagging of the materials to be packaged and ensuring the final packaging efficiency. Specifically, the bag-supporting mechanism 4 can use the upper suction nozzle 402 to suck up the upper layer of the packaging bag and move it upward, so that the bag opening of the packaging bag is opened. Then, the left and right bag-supporting components will expand the bag opening of the packaging bag to ensure that the opening size is large enough for the feeding mechanism 3 to smoothly transfer the packaging material into the packaging bag. Then, the flexible pressing component 406 will press down the packaging material inside the packaging bag so that the feeding mechanism will not bring out the packaging material inside when it exits the packaging bag.

[0025] As a preferred embodiment of this invention, it should be further explained that a first extension frame 408 is fixed on the side of the bag support bracket 401 near the discharge conveyor 2. The first extension frame 408 extends towards the discharge conveyor 2, so that the upper suction nozzle assembly and the lower pressing assembly are both located above the conveyor belt. The first driving member 403 and the third driving member 407 are both installed on the first extension frame 408 to ensure its stability. The upper suction nozzle 402 is located between the bag support bracket 401 and the flexible lower pressing member 406, so that the upper suction nozzle 402 is aligned with the bag opening of the packaging bag, and the flexible lower pressing member 406 is aligned with the middle or bottom of the packaging bag, so that the structure is reasonably arranged and the bagging is smooth.

[0026] Furthermore, both the first driving component 403 and the third driving component 407 are cylinders, and the flexible pressing component 406 is a sponge with a fixed plate connected to its upper end. The telescopic rod of the third driving component 407 is connected to the fixed plate to achieve flexible pressing of the packaging bag. This will not damage the packaging material inside, nor will it cause too much friction when the feeding mechanism 3 exits due to excessive pressing force. The discharge conveyor 2 is a bag-supporting belt conveyor. Multiple suction nozzles are provided below the conveyor belt of the discharge conveyor 2. Multiple through holes are evenly distributed on the conveyor belt to facilitate the suction nozzles to pick up the lower layer of the packaging bag. The through holes can be round holes or elongated holes. In automated production, each packaging bag is evenly placed on the conveyor belt, so that each location of the packaging bag on the conveyor belt is provided with a through hole. Then, by contacting the contact switch, the through holes can also be accurately moved to the designated position of the suction nozzle.

[0027] As a preferred embodiment of this invention, it should be further explained that the left bag support assembly includes a vertically arranged left bag support mounting plate 409, and the right bag support assembly includes a vertically arranged right bag support mounting plate 410. Both the left bag support mounting plate 409 and the right bag support mounting plate 410 are connected to the bag support driving assembly, so as to control the left bag support mounting plate 409 and the right bag support mounting plate 410 to move closer to each other or further away from each other through the bag support driving assembly. Both the left bag support mounting plate 409 and the right bag support mounting plate 410 are equipped with bag support handles for opening the bag opening, so that the bag support handles can move closer to each other or further away from each other through the relative movement of the left bag support mounting plate 409 and the right bag support mounting plate 410. When the bag support handles move closer to each other, they can easily enter the bag opening of the packaging bag, and when the bag support handles move further away from each other, they can easily open the bag opening of the packaging bag.

[0028] Furthermore, the bag-supporting gripper includes a lower bag-supporting claw 411 and an upper bag-supporting claw 412. The lower bag-supporting claw 411 is fixed on the side of the left bag-supporting mounting plate 409 and the right bag-supporting mounting plate 410 that is close to each other. The upper bag-supporting claw 412 is provided above the two lower bag-supporting claws 411, so that each lower bag-supporting claw 411 and one upper bag-supporting claw 412 are vertically corresponding. The side of the left bag-supporting mounting plate 409 and the right bag-supporting mounting plate 410 that is away from each other is equipped with a fourth driving member 413 located above the lower bag-supporting claw 411. The fourth driving member 413 is a cylinder, hydraulic cylinder or electric cylinder. A connecting sleeve is connected to the telescopic rod of the fourth driving member 413. The connecting sleeve is sleeved on the outside of the corresponding left bag-supporting mounting plate 409 or right bag-supporting mounting plate 410. The side of the connecting sleeve away from the fourth driving member 413 is connected to the corresponding upper bag-supporting claw 412, so that the fourth driving member 413 can drive the upper bag-supporting claw 412 to move up and down. Before the bag-holding gripper moves to the bag opening position, the fourth drive component 413 controls the upper bag-holding claw 412 to move downward and engage with the corresponding lower bag-holding claw 411 below, so that the upper bag-holding claw 412 and the lower bag-holding claw 411 can smoothly enter the bag opening. Then, the fourth drive component 413 drives the upper bag-holding claw 412 to move upward, and the bag-holding drive component drives the left bag-holding mounting plate 409 and the right bag-holding mounting plate 410 to move away from each other, which can drive the two sides of the bag opening to separate from each other, completing the opening action of the bag opening. The structure operates stably and can ensure the opening size, thereby enabling the feeding mechanism 3 to stably transfer the material to be packaged into the packaging bag.

[0029] As a preferred embodiment of this invention, it should be further explained that the bag-supporting drive assembly includes a first guide rail 414 disposed at the bottom of the slide plate 404. The extension direction of the first guide rail 414 is parallel to the conveying direction of the conveyor belt. Two sliders 415 are slidably connected to the first guide rail 414. The two sliders 415 are respectively fixedly connected to the left bag-supporting mounting plate 409 and the right bag-supporting mounting plate 410, so that the left bag-supporting mounting plate 409 and the right bag-supporting mounting plate 410 can slide stably along the first guide rail 414. Both ends of the slide plate 404 are rotatably connected to bag-supporting pulleys 416. The pulley 416 is connected to the bag-supporting belt 417 sleeved on the slider 415. The two sliders 415 are respectively connected to the two sides of the bag-supporting belt 417, so that when the belt 417 rotates, the two sliders 415 can slide in opposite directions. The upper end of the slide plate 404 is equipped with a stepper motor 418. The motor shaft of the stepper motor 418 is connected to a bag-supporting pulley 416 for transmission, so as to drive the bag-supporting pulley 416 connected to it to rotate forward or backward through the stepper motor 418, thereby controlling the left bag-supporting mounting plate 409 and the right bag-supporting mounting plate 410 to move closer to each other or further away from each other.

[0030] Furthermore, each of the two sliders 415 is fixed with a first clamping block located inside the bag support belt 417. Each of the two first clamping blocks is bolted to a second clamping block located outside the bag support belt 417. The first clamping block and the corresponding second clamping block cooperate to clamp the bag support belt 417. Through the clamping cooperation between the first clamping block and the second clamping block, the slider can be stably fixed in the corresponding position of the belt. This ensures that when the bag support belt 417 rotates, it can synchronously drive the two sliders to move in opposite directions. It also facilitates the disassembly and adjustment of the connection position between the slider 415 and the bag support belt 417, improving the convenience of component assembly and maintenance.

[0031] Furthermore, a first contact switch 419 is installed on one side of the slide plate 404, and a first contact block 420 is installed on the second clamping block located on the same side as the first contact switch 419. As the second clamping block moves, the upper part of the first contact block 420 can contact and trigger the first contact switch 419. When the first contact block 420 triggers the first contact switch 419, the first contact switch 419 will send a signal to the controller of the device to control the stepper motor to stop rotating, thereby precisely limiting the maximum travel distance between the left and right bag support mounting plates, and thus precisely controlling the size of the bag opening when the packaging bag is opened.

[0032] As a preferred embodiment of this invention, it should be further explained that the bag support bracket 401 includes two parallel vertical plates, and a second guide rail 421 is installed at the upper end of each of the two vertical plates. The extension direction of the second guide rail 421 is perpendicular to the conveying direction of the conveyor belt. The two ends of the slide plate 404 are slidably connected to the two second guide rails 421 respectively. By setting the second guide rails 421 to guide and support the slide plate 404, the stability of the slide plate 404 during the overall movement can be improved, and the slide plate 404 can be prevented from tilting and swaying when it drives the bag support component to move, so as to ensure that the bag support operation can be completed accurately and stably.

[0033] Furthermore, a second extension frame 422 is fixed on the side of the feeding conveyor 1 away from the conveyor belt. A second driving component 405 is installed on the second extension frame 422. The second driving component 405 is a cylinder, hydraulic cylinder, or electric cylinder. A push plate 423 is installed on the telescopic rod of the second driving component 405. The push plate 423 is connected to the slide plate 404. The second driving component 405 can push the slide plate 404 to move stably along the second guide rail through the push plate 423, thereby driving the slide plate 404 and the entire bag-supporting component installed on the slide plate 404 to move laterally as a whole, completing the position switching between the bag-supporting station and the bag-packing station. No manual movement or adjustment is required. It can adapt to the operation process of the automated packaging production line and improve the automation level of the overall packaging operation.

[0034] As a preferred embodiment of this invention, it should be further noted that the invention also includes a feeding mechanism 5 and a sealing mechanism 6. Both the feeding mechanism 5 and the sealing mechanism 6 can be based on existing technologies and are not specifically limited. Feeding mechanisms 5 are installed on both sides of the input end of the feeding conveyor 1 to facilitate automated feeding. The sealing mechanism 6 is installed on one side of the discharge conveyor 2 between the bag-supporting mechanism 4 and the output end of the discharge conveyor 2, enabling the sealing of the packaging bags after packaging. More preferably, the inlet end of the discharge conveyor 2 can be equipped with existing pressure roller mechanism and heat-sealing mechanism. The pressure roller mechanism stably releases the connected packaging bags, and the heat-sealing mechanism cuts the connected packaging bags into smaller packaging bags of a specified size, thereby using these smaller packaging bags to package the materials to be packaged.

[0035] Example 2: This embodiment makes further improvements based on Embodiment 1. In order to achieve stable conveying of the materials to be packaged, this embodiment provides a specific feeding mechanism 3, such as... Figure 6 , Figure 7 and Figure 8 As shown, the feeding mechanism 3 includes a fixed frame 301, a feeding plate 302, and an electric conveyor rail. The fixed frame 301 can serve as the base of the feeding mechanism, facilitating the installation of the entire assembly at a designated location, such as the outlet of the conveyor belt. The electric conveyor rail is mounted on the fixed frame 301, and the feeding plate 302 is positioned below the electric conveyor rail. In practice, the feeding plate 302 can be positioned at the outlet of the feeding conveyor 1, where small parts and materials such as instruction manuals, remote controls, and data cables to be packaged are placed together. These materials are then conveyed to the feeding plate 302 by the feeding conveyor 1, and then, under the control of the electric conveyor rail, the materials to be packaged on the feeding plate 302 are transferred to the packaging bag.

[0036] The electric conveyor rail includes an integrated plate 303, a conveyor rail, a conveyor slider 304, and a motor drive assembly. The integrated plate 303 is mounted on a fixed frame 301, serving as the base of the electric conveyor rail. The conveyor rail is located on the bottom surface of the integrated plate 303. The conveyor slider 304 is slidably connected to the conveyor rail. The motor drive assembly is mounted on the integrated plate 303 and connected to the conveyor slider 304, driving the conveyor slider 304 to reciprocate along the conveyor rail, precisely controlling the feeding plate 302 between the receiving station and the packaging station. One end of the feeding plate 302 is fixed with an upwardly extending connecting plate 305, the upper end of which is connected to the conveyor slider 304, thereby using the conveyor slider 304 to move the feeding plate 302.

[0037] As a preferred embodiment of this invention, it should be further explained that the motor drive assembly includes a conveying motor 306, a first pulley 307, a second pulley 308, and an annular belt 309. The first pulley 307 and the second pulley 308 are rotatably connected to both ends of the bottom surface of the integrated plate 303, respectively. The two ends of the annular belt 309 are respectively wound around the first pulley 307 and the second pulley 308. The conveying guide rail is located between the first pulley 307 and the second pulley 308 inside the annular belt 309. The conveying slider 304 is connected to the annular belt 309 on one side of the conveying guide rail. 09 is connected; the conveyor motor 306 is mounted on the integrated plate 303, and the motor shaft of the conveyor motor 306 is coaxially connected with the first pulley 307. When in use, after the conveyor motor 306 is started, it will drive the first pulley 307 to rotate, and drive the second pulley 308 to rotate synchronously through the transmission of the annular belt 309, thereby driving the conveyor slider 304 connected to the annular belt 309 to slide back and forth along the conveyor guide rail, realizing the precise movement of the feeding plate 302 between the receiving station and the packaging station. The overall transmission structure is stable, the transmission accuracy is high, and it can stably adapt to the feeding requirements of automated packaging.

[0038] Furthermore, two clamping plates 310 are clamped on the annular belt 309 on one side of the conveying guide rail. The two clamping plates 310 are respectively set on both sides of the annular belt 309, and the two clamping plates 310 are detachably connected by bolts. One of the clamping plates 310 is connected to the conveying slider 304. This split clamping connection method can not only ensure the stability of the connection between the annular belt and the conveying slider and avoid the problem of slippage and loosening during transmission, but also facilitate disassembly and maintenance. When the belt is worn or the slider installation position needs to be adjusted, it is not necessary to disassemble the entire belt drive structure. The adjustment or replacement can be completed simply by loosening the connecting bolts between the two clamping plates, which reduces the maintenance difficulty and maintenance cost.

[0039] As a preferred embodiment of this invention, it should be further explained that the upper end of the integrated plate 303 is connected to an inverted U-shaped guide frame 311, and a guide plate is provided on the top of the fixed frame 301. One end of the guide plate is sleeved inside the inverted U-shaped guide frame 311. A spacing adjustment guide rail 312 is provided on the top surface of the guide plate. Preferably, two spacing adjustment guide rails 312 are provided to improve stability. The extension direction of the spacing adjustment guide rail 312 is perpendicular to the extension direction of the conveying guide rail. A spacing adjustment slider 313 is fixed inside the inverted U-shaped guide frame 311 and slidably connected to the spacing adjustment guide rail 312. A spacing adjustment component is installed between the inverted U-shaped guide frame 311 and the guide plate to control the movement of the inverted U-shaped guide frame 311 along the spacing adjustment guide rail 312. This structure allows adjustment of the distance between the feeding plate and the conveyor belt outlet, adapting to the feeding and positioning requirements of different specifications of packaged materials.

[0040] Furthermore, the spacing adjustment assembly includes two parallel fixing blocks 314 fixed to the guide plate, with an adjusting screw 315 rotatably connected between the two fixing blocks 314. The middle part of the adjusting screw 315 is threadedly connected to the inverted U-shaped guide frame 311, and one end of the adjusting screw 315 passes through a fixing block 314 and is equipped with a handwheel. In use, rotating the handwheel will drive the adjusting screw to rotate between the two fixing blocks. Since the adjusting screw is threadedly engaged with the inverted U-shaped guide frame, and the inverted U-shaped guide frame is slidably connected to the spacing adjustment guide rail through the spacing adjustment slider, rotating the adjusting screw will cause the inverted U-shaped guide frame to move linearly along the extension direction of the spacing adjustment guide rail, thereby driving the integrated plate and the feeding plate mounted on the integrated plate to move synchronously, completing the spacing adjustment of the feeding position. The entire adjustment process is simple to operate, provides stable positioning, and can quickly adapt to the feeding and positioning requirements of different specifications of packaged materials.

[0041] As a preferred embodiment of this invention, it should be further explained that two second contact switches 316 for controlling the power supply of the motor drive assembly are installed on one side of the integrated plate 303. A second contact block 317 is provided between the two second contact switches 316. The lower end of the second contact block 317 is connected to another fixed block 314. In practice, when the conveyor slider moves, it will drive the fixed block 314 to slide together, and then drive the second contact block 317 to slide together. When the second contact block 317 touches the second contact switch 316 that is closer to the packaging station, the second contact switch 316 controls the conveyor motor 306 to de-energize through the processor. Then, after the conveyor motor 306 is turned on again as needed, the conveyor motor 306 drives the conveyor slider to slide in the reverse direction. When the second contact block 317 touches the other second contact switch 316, the conveyor motor 306 is de-energized again, and the feeding plate 302 moves to the receiving station.

[0042] Furthermore, an elongated positioning groove 318 extending along the length direction is installed on one side of the integrated plate 303. Two second contact switches 316 are each installed on an adjusting block 319. The adjusting block 319 is slidably connected to the elongated positioning groove 318. The adjusting block 319 is locked and fixed to the integrated plate 303 by locking bolts. After loosening the locking bolts, the second contact switches 316 can be driven to slide along the elongated positioning groove, changing the distance between the two contact switches 16, thereby adjusting the movement stroke of the feeding plate between the packaging station and the receiving station. This can further adapt to the feeding needs of packaging materials of different lengths and specifications, and the adaptability is more flexible.

[0043] Furthermore, the fixing frame 301 includes a base plate, side vertical plates and the guide plate. The base plate and the guide plate are arranged in parallel. The two ends of the side vertical plates are perpendicularly connected to one end of the base plate and the other end of the guide plate, respectively. The structure is simple and can leave enough space for the feeding plate 302 to place the workpiece to be packaged.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
