Description

Technical Field

[0001] The present invention relates to the technical field of feeding equipment, and particularly relates to a feeding mechanism for a packaging machine for producing sports diets. Background Art

[0002] A packaging machine is a type of machine that packages products, playing a role in protection and aesthetics. Packaging machines are mainly divided into two aspects: one is the overall production packaging in a production line manner, and the other is the peripheral packaging equipment for products. The overall production packaging in a production line manner is applied to food, medicine, daily chemicals, hardware, lighting, sealing machines, coding, and mainly includes: liquid (paste) filling machines, pillow packaging machines, horizontal packaging machines, vertical packaging machines, powder and granule packaging machines, bag-type automatic packaging machines, frozen product automatic packaging machines, etc. Sports diets refer to foods designed specifically for sports people, including protein powders, nutritional powders, etc. During the processing of such powdered foods, usually, the feeding mechanism of a packaging machine is used to add the powder to plastic packaging bags, and then the plastic packaging bags are sealed for use.

[0003] The Chinese patent document with the publication number CN217625999U discloses a powder homogenization automatic quantitative packaging machine, including a fixed frame. A conveying mechanism is fixedly installed at the bottom of the fixed frame. A hopper is fixedly connected to the inner wall of the fixed frame. A cylinder is fixedly installed on the right side of the inner wall of the fixed frame. Upper and lower clamping grooves are formed in the inner wall of the hopper. A sealing plate is hermetically clamped inside the lower clamping groove. A connecting plate is fixedly connected to the right side of the sealing plate. The connecting plate is fixedly connected to the telescopic end of the cylinder. An adaptor bar is fixedly connected to the left side of the sealing plate. A through groove is formed at the bottom of the inner wall of the sealing plate. A placement groove is formed in the inner wall of the sealing plate. A connecting bar is slidably installed at the top of the placement groove. An adaptor plate and a moving plate are fixedly connected to the left side of the connecting bar. The right side of the connecting bar penetrates through the sealing plate and is fixedly connected to the connecting plate.

[0004] During operation, first, the packaging bag is placed on the top of the conveyor belt and is located directly below the hopper. Then, the material is fed. The material falls downward along the through groove and enters the packaging bag, completing the automatic quantitative packaging of the material. Subsequently, the motor is started to drive the conveyor belt to rotate, so that the packaged material is driven by the conveyor belt and undergoes the next sealing operation.

[0005] In the above technology, when the material is loaded, the material enters the packaging bag from the top of the packaging bag. During the continuous loading of the material, the powder in the packaging bag will be impacted, thereby generating dust. As the material is loaded, the dust will adhere to the top of the packaging bag. When the top of the packaging bag is sealed subsequently, the dust will be encapsulated at the sealing part of the packaging bag, thereby resulting in poor packaging quality of the material. Summary of the Invention

[0006] The present invention provides a feeding mechanism for a packaging machine used in the production of sports diets, aiming to solve the technical problem in the prior art that when materials enter the packaging bag from the top of the packaging bag, during the continuous filling process of the materials, the powder in the packaging bag will be impacted, thus generating dust. As the materials are filled, the dust will adhere to the top of the packaging bag. When sealing the top of the packaging bag subsequently, the dust will be encapsulated at the sealing part of the packaging bag, thereby resulting in poor packaging quality of the materials.

[0007] A feeding mechanism for a packaging machine used in the production of sports diets according to the present invention includes a frame, a filling head arranged on the frame, and a feeding assembly for feeding materials into the filling head. The feeding assembly is used to convey the materials into the filling head, and the filling head is used to fill the materials conveyed into the filling head into the packaging bag. A dust-proof mechanism is arranged on the filling head. The dust-proof mechanism includes a mounting frame arranged on the filling head and a dust-proof bag for blocking and opening the packaging bag. The dust-proof bag is arranged on the mounting frame. The dust-proof bag is set as a hollow structure. The dust-proof bag is provided with a feed inlet and a discharge outlet. The feed inlet is communicated with the filling head. An adjusting mechanism for controlling the opening and closing of the discharge outlet is arranged on the mounting frame. When filling materials, the mounting frame drives the dust-proof bag to extend into the bottom of the packaging bag. The materials enter the dust-proof bag and squeeze the dust-proof bag. The dust-proof bag is expanded and abuts against the inner wall of the packaging bag. At this time, the adjusting mechanism opens the discharge outlet, and the mounting frame drives the dust-proof bag to rise, and the materials are filled into the packaging bag through the discharge outlet.

[0008] By adopting the above technical solution, through the setting of the dust-proof mechanism and the adjusting mechanism, when adding materials into the packaging bag, the filling head drives the dust-proof mechanism and the adjusting mechanism to slide into the packaging bag, and the dust-proof bag extends into the bottom of the packaging bag. At this time, the materials in the filling head enter the dust-proof bag through the feed inlet. The dust-proof bag is expanded and abuts against the inner wall of the packaging bag. At the same time, the adjusting mechanism opens the discharge outlet, and the mounting frame drives the dust-proof bag to rise, and the materials are filled into the packaging bag through the discharge outlet. The dust generated during the filling process of the materials can be intercepted by the dust-proof bag, reducing the phenomenon that dust adheres to the top of the packaging bag, thereby improving the packaging quality of the materials.

[0009] Preferably, the mounting frame includes a movable frame arranged in the filling head and a fixed frame arranged at the bottom end of the dust-proof bag. The movable frame is connected to the top of the dust-proof bag.

[0010] By adopting the above technical solution, through the setting of the movable frame and the fixed frame, the installation of the top and bottom of the dust-proof bag can be realized.

[0011] Preferably, the adjusting mechanism includes an adjusting frame arranged in the filling head and a blocking plate for controlling the opening and closing of the discharge outlet. The blocking plate is connected to the adjusting frame.

[0012] By adopting the above technical solution, through the setting of the blocking plate, when the adjusting frame is adjusted, the blocking plate can be driven to be adjusted. When the blocking plate abuts against the fixed frame, the discharge port is closed. When the blocking plate no longer abuts against the fixed frame, the discharge port is opened.

[0013] Preferably, the adjusting frame includes an adjusting plate slidably engaged with the loading head along the height direction of the loading head and an adjusting rod disposed on the adjusting plate, and the adjusting rod is connected to the blocking plate.

[0014] By adopting the above technical solution, by driving the adjusting plate to slide along the height direction of the loading head, the adjusting rod can be driven to slide, and the adjusting rod drives the blocking plate to slide. When the blocking plate slides and no longer blocks the bottom of the fixed frame, the discharge port is opened. When the blocking plate blocks the bottom of the fixed frame, the discharge port is closed.

[0015] Preferably, a driver for driving the adjusting plate to slide is disposed in the loading head.

[0016] By adopting the above technical solution, through the setting of the driver, when the driver is started, the adjusting plate can be driven to slide, realizing the convenient sliding adjustment of the adjusting plate.

[0017] Preferably, an elastic member for adjusting the distance between the adjusting rod and the movable frame is disposed on the adjusting rod, one end of the elastic member is connected to the adjusting rod, and the other end is connected to the movable frame.

[0018] By adopting the above technical solution, through the setting of the elastic member, the distance between the adjusting rod and the movable frame can be adjusted, thereby adjusting the distance between the upper surface of the blocking plate and the lower surface of the fixed frame. When the upper surface of the blocking plate fits against the lower surface of the fixed frame, the blocking plate blocks the discharge port. When there is a gap between the upper surface of the blocking plate and the lower surface of the fixed frame, the discharge port is opened.

[0019] Preferably, a limiting sleeve is disposed at the bottom of the loading head, and a flange vertically adapted to the limiting sleeve is disposed at the bottom end of the fixed frame. When the fixed frame rises, after the flange abuts against the bottom end of the limiting sleeve, the fixed frame stops rising.

[0020] By adopting the above technical solution, through the setting of the limiting sleeve, when the fixed frame rises, after the flange of the fixed frame abuts against the bottom end of the limiting sleeve, the fixed frame stops rising. At this time, the adjusting plate and the adjusting rod can continue to rise, and the adjusting rod drives the blocking plate to block the discharge port, realizing the reset of the blocking plate.

[0021] Preferably, a material falling inclined surface is disposed on the blocking plate, and the material falling inclined surface is inclined downward along the direction away from the adjusting rod.

[0022] By adopting the above technical solution, through the setting of the blanking inclined plane, the materials on the blocking plate can slide along the blocking plate, reducing the phenomenon that materials are likely to remain on the blocking plate.

[0023] Preferably, the adjusting rod passes through the fixed frame, and vibration bumps for driving the blocking plate to vibrate vertically are arranged on the adjusting rod.

[0024] By adopting the above technical solution, through the setting of the vibration bumps, when the adjusting rod drives the vibration bumps to rise, when the vibration bumps pass through the fixed frame, the blocking plate can be driven to vibrate in the vertical direction, thereby shaking off the materials on the blocking plate and further reducing the phenomenon that materials are likely to remain on the blocking plate.

[0025] Preferably, the dust-proof bag comprises a plurality of folding cloths, and the plurality of folding cloths are arranged in a circle along the central axis of the filling head and are connected to each other.

[0026] By adopting the above technical solution, through the setting of the plurality of folding cloths, when the dust-proof bag enters the packaging bag, when the plurality of folding cloths expand, the packaging bag can be blocked, and when the plurality of folding cloths are folded, the packaging bag is no longer blocked, making the use of the dust-proof bag more convenient.

[0027] The beneficial effects of the present invention are as follows: 1. In the present invention, through the setting of the dust-proof mechanism and the adjusting mechanism, when it is necessary to add materials into the packaging bag, the filling head drives the dust-proof mechanism and the adjusting mechanism to slide into the packaging bag, the dust-proof bag extends into the bottom of the packaging bag. At this time, the materials in the filling head enter the dust-proof bag through the feed port, the dust-proof bag is expanded and abuts against the inner wall of the packaging bag, and at the same time, the adjusting mechanism opens the discharge port, the mounting rack drives the dust-proof bag to rise, and the materials are filled into the packaging bag through the discharge port. The dust generated during the filling process of the materials can be intercepted by the dust-proof bag, reducing the phenomenon that dust adheres to the top of the packaging bag, thereby improving the packaging quality of the materials.

[0028] 2. In the present invention, through the setting of the elastic member, the distance between the adjusting rod and the movable frame can be adjusted, so as to adjust the distance between the upper surface of the blocking plate and the lower surface of the fixed frame. When the upper surface of the blocking plate fits against the lower surface of the fixed frame, the blocking plate blocks the discharge port. When there is a gap between the upper surface of the blocking plate and the lower surface of the fixed frame, the discharge port is opened; 3. In the present invention, through the setting of the vibration bumps, when the adjusting rod drives the vibration bumps to rise, when the vibration bumps pass through the fixed frame, the blocking plate can be driven to vibrate in the vertical direction, thereby shaking off the materials on the blocking plate and further reducing the phenomenon that materials are likely to remain on the blocking plate.

Detailed Description of the Invention

[0036] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0037] Refer to Figures 1-6, A feeding mechanism for a packaging machine for producing sports diets according to the present invention includes a frame 1, a filling head 2 provided on the frame 1, a feeding assembly (not shown in the figure) for feeding materials into the filling head 2, a dust-proof mechanism 3 provided on the filling head 2, and a clamping mechanism 8 provided on the frame 1. The feeding assembly is used to convey materials into the filling head 2. The feeding assembly includes a feeding pipe, a feeding member connected to the feeding pipe, and a feeding cylinder. One end of the feeding pipe is connected to the filling head 2, and the other end is connected to the feeding member, which is used to convey the materials conveyed into the feeding pipe by the feeding member into the filling head 2. The feeding cylinder is used to store the materials. The feeding member can directly adopt a screw conveyor, and the screw conveyor is used to convey the materials in the feeding cylinder into the feeding pipe. A plurality of filling heads 2 are evenly arranged along the central axis direction of the frame 1. The filling head 2 is used to fill the materials conveyed into the filling head 2 into the packaging bag. A plurality of clamping mechanisms 8 are provided, and the clamping mechanisms 8 are arranged corresponding to the filling heads 2. A rotating mechanism for driving a plurality of clamping mechanisms 8 to rotate is provided on the frame 1. The dust-proof mechanism 3 is used to intercept the dust generated when the filling head 2 adds materials to the packaging bag. When the materials need to be filled, first clamp the packaging bag through the clamping mechanism 8, then start the screw conveyor, convey the materials from the feeding cylinder into the feeding pipe through the screw conveyor, then enter the filling head 2 through the feeding pipe, and fill the materials into the packaging bag through the filling head 2 to convey the materials. During the filling process of the filling head 2, intercept the dust generated during the filling process through the dust-proof mechanism 3. After the materials are filled, complete the packaging operation of the materials, then drive the clamping mechanism 8 to rotate through the rotating mechanism, drive the subsequent packaging bags to rotate, and perform continuous packaging operations.

[0038] Among them, referring to Figure 1 and Figure 2 , the clamping mechanism 8 includes two jaws 81 and a clamping assembly 82 for driving the jaws 81 to move. The two jaws 81 are arranged oppositely and are used to fixedly clamp both sides of the packaging bag. When the packaging bag needs to be clamped, first place the packaging bag between the two jaws 81, and then drive the two jaws 81 to move through the clamping assembly 82. The two jaws 81 fixedly clamp the packaging bag. When the packaging bag needs to be unlocked, drive the two jaws 81 to move through the clamping assembly 82, so that the two jaws 81 are away from the packaging bag, and the two jaws 81 no longer fixedly clamp the packaging bag.

[0039] Referring to Figures 2-4, the dust-proof mechanism 3 includes a mounting bracket 31 disposed on the filling head 2 and a dust-proof bag 32 for sealing and opening the packaging bag. The mounting bracket 31 includes a movable bracket 311 disposed inside the filling head 2 and a fixed bracket 312 disposed at the bottom end of the dust-proof bag 32. The movable bracket 311 is fixedly connected to the top of the dust-proof bag 32. The movable bracket 311 includes a circular ring fixedly connected to the top of the dust-proof bag 32 and a T-shaped plate fixedly disposed on the circular ring. A flange 313 is provided at the bottom end of the fixed bracket 312, and the top end of the fixed bracket 312 is fixedly connected to the bottom end of the dust-proof bag 32; the dust-proof bag 32 is provided as a hollow structure, the dust-proof bag 32 is vertically arranged, the dust-proof bag 32 is provided with a feed inlet and a discharge outlet. The feed inlet is communicated with the filling head 2 for allowing the material in the filling head 2 to enter the dust-proof bag 32, and the discharge outlet is for allowing the material in the dust-proof bag 32 to enter the packaging bag. The dust-proof bag 32 includes a plurality of folding cloths 321. The folding cloths 321 are made of cloth. The plurality of folding cloths 321 are arranged in a circle along the central axis of the filling head 2, and the plurality of folding cloths 321 are fixedly connected to each other.

[0040] Referring to Figures 3-6 , an adjusting mechanism 4 for controlling the opening and closing of the discharge outlet is provided on the mounting bracket 31. When filling the material, the mounting bracket 31 drives the dust-proof bag 32 to extend into the bottom end of the packaging bag. Then the material enters the dust-proof bag 32 and presses the dust-proof bag 32. The dust-proof bag 32 is expanded and abuts against the inner wall of the packaging bag. At this time, the distance between the movable bracket 311 and the fixed bracket 312 is reduced, and the adjusting mechanism 4 opens the discharge outlet. During the process of the mounting bracket 31 driving the dust-proof bag 32 to rise, the material can pass through the discharge outlet and be gradually filled into the packaging bag. After the material filling is completed, the discharge outlet is closed by the adjusting mechanism 4. Among them, the use of the dust-proof bag 32 can intercept the dust generated during the filling process of the material in the packaging bag, reduce the phenomenon that the dust adheres to the top of the packaging bag, thereby improving the packaging quality of the material.

[0041] Among them, referring to Figures 3-6, the adjusting mechanism 4 includes an adjusting frame 41 disposed in the loading head 2 and a sealing plate 42 for controlling the opening and closing of the discharge port. The sealing plate 42 is connected to the adjusting frame 41. The adjusting frame 41 includes an adjusting plate 411 slidably engaged with the loading head 2 along the height direction of the loading head 2 and an adjusting rod 412 fixedly disposed on the adjusting plate 411. The adjusting plate 411 is a rectangular plate. A limiting sleeve 6 is fixedly disposed at the bottom of the loading head 2. A groove for the vertical sliding of the adjusting plate 411 is formed on the limiting sleeve 6. A driver (not shown in the figure) for driving the sliding of the adjusting plate 411 is disposed in the loading head 2. The driver directly adopts a hydraulic cylinder or a pneumatic cylinder. The cylinder body of the driver is fixedly connected to the loading head 2, and the piston rod of the driver is fixedly connected to the adjusting plate 411. When the driver is started, the driver can drive the adjusting plate 411 to perform lifting adjustment in the limiting sleeve 6. The adjusting plate 411 drives the adjusting rod 412 and the sealing plate 42 to perform lifting adjustment. The sealing plate 42 slides towards the bottom end of the fixed frame 312 and abuts against the bottom end of the fixed frame 312, and can block the fixed frame 312; the flange 313 is vertically adapted to the limiting sleeve 6. When the fixed frame 312 rises and the upper surface of the flange 313 abuts against the bottom end of the limiting sleeve 6, the fixed frame 312 stops rising.

[0042] Refer to Figure 3 , Figure 4 and Figure 6 , the adjusting rod 412 passes through the fixed frame 312. The adjusting rod 412 is slidably engaged with the fixed frame 312 along the vertical direction. The adjusting rod 412 is slidably engaged with the movable frame 311 along the vertical direction. An elastic member 5 for adjusting the distance between the adjusting rod 412 and the movable frame 311 is disposed on the adjusting rod 412. The elastic member 5 is vertically disposed. The elastic member 5 directly adopts a spring. One end of the elastic member 5 is fixedly connected to the adjusting rod 412, and the other end is fixedly connected to the movable frame 311. In the initial state, due to the setting of the elastic member 5, there is a gap between the top end of the sealing plate 42 and the bottom end of the limiting sleeve 6; a vibration convex block 7 for driving the sealing plate 42 to vibrate vertically is fixedly disposed on the outer peripheral surface of the adjusting rod 412. The vibration convex block 7 is set as an arc block. A plurality of vibration convex blocks 7 are spaced along the length direction of the adjusting rod 412. The vibration convex block 7 is directly made of an elastic rubber material; the sealing plate 42 is set as a conical structure. The top of the sealing plate 42 is the small end, and the bottom of the sealing plate 42 is the large end. A blanking inclined surface 421 is disposed on the sealing plate 42. The blanking inclined surface 421 is inclined downward along the direction away from the adjusting rod 412. The bottom end of the adjusting rod 412 is fixedly connected to the upper surface of the sealing plate 42.

[0043] The implementation principle of a feeding mechanism of a packaging machine for producing sports diets in the present invention is as follows: when it is necessary to load materials, first place the packaging bag between two clamping jaws 81, and then drive the two clamping jaws 81 to move through the clamping assembly 82, and the two clamping jaws 81 fixedly clamp the packaging bag; Then start the driver, and the driver drives the adjusting plate 411 to descend. The adjusting plate 411 drives the adjusting rod 412, the elastic member 5, the movable frame 311, the fixed frame 312, the dust-proof bag 32 and the blocking plate 42 to descend. After the dust-proof bag 32 and the blocking plate 42 descend to the bottom end of the packaging bag, turn off the driver. Then, load materials into the packaging bag through the feeding assembly and the filling head 2. During the filling process, the materials enter the dust-proof bag 32 through the feeding port in the filling head 2. At this time, the materials will squeeze the dust-proof bag 32, and multiple folding cloths 321 of the dust-proof bag 32 are opened and abutted against the inner wall of the packaging bag, and the bottom of the dust-proof bag 32 blocks the packaging bag; Subsequently, start the driver, and the driver drives the adjusting plate 411 to rise. The adjusting plate 411 drives the adjusting rod 412, the elastic member 5, the movable frame 311, the fixed frame 312, the dust-proof bag 32 and the blocking plate 42 to rise. During the rising process of the dust-proof bag 32 and the blocking plate 42, the materials can fall from the gap between the dust-proof bag 32 and the blocking plate 42 and enter the packaging bag for the filling operation of the materials. At the same time, multiple folding cloths 321 are opened. After the bottom of the dust-proof bag 32 blocks the packaging bag and fills the materials, the bottom of the dust-proof bag 32 can always intercept the dust generated during the filling process of the materials, so that the dust cannot move to the top of the packaging bag, reducing the phenomenon that the dust adheres to the top of the packaging bag, thereby improving the packaging quality of the materials; During the process of filling the materials into the packaging bag, when the movable frame 311 drives the dust-proof bag 32 and the fixed frame 312 to retract into the limit sleeve 6, the dust-proof bag 32 will be gradually folded and reset. When the packaging bag is filled, the flange 313 of the fixed frame 312 abuts against the lower surface of the limit sleeve 6. At this time, the movable frame 311, the dust-proof bag 32 and the fixed frame 312 no longer rise. When the driver drives the adjusting plate 411 to continue rising, it can drive the adjusting rod 412, the elastic member 5 and the blocking plate 42 to rise; When the vibration bump 7 on the adjusting rod 412 moves to the fixed frame 312, the vibration bump 7 squeezes the fixed frame 312 and cooperates with the elastic member 5, so that during the rising process of the blocking plate 42, intermittent vibration movement will be generated. During the vibration process of the blocking plate 42, the materials on the blocking plate 42 will be shaken off, thereby reducing the phenomenon that the materials remain on the blocking plate 42; When the blocking plate 42 rises and abuts against the fixed frame 312 to block the discharge port, the filling is completed. At this time, the driver no longer drives the adjusting plate 411 to rise. After the limit sleeve 6 is separated from the packaging bag, then drive the clamping mechanism 8 to rotate through the rotating mechanism, drive the subsequent packaging bags to rotate, and perform continuous filling operations.
