Description

Technical Field

[0001] The invention relates to the technical field of feed packaging, and in particular to packaging equipment and a method for producing fermented biological feed. Background Art

[0002] Fermented biological feed refers to feed that is made by fermenting the complex ingredients in feed raw materials, such as starch, protein, cellulose, etc., into nutrients that are easy for animals to digest and absorb. During production, it needs to be packaged using packaging equipment for storage and transportation.

[0003] A patent application document with publication number CN116750287A discloses a feed packaging machine, including a feeding mechanism arranged at the top of a frame, a sealing and packaging mechanism arranged below the feeding mechanism, a feeding mechanism arranged at one side of the frame and used to provide packaging sealing materials to the feeding mechanism, and a belt conveyor arranged below the sealing and packaging mechanism; the feed falls through the feeding mechanism into the sealing and packaging mechanism, is sealed by the sealing and packaging mechanism, and then bags of feed fall onto the belt conveyor for transportation.

[0004] However, the following problems still exist in this scheme. When the feed is put into the packaging bag, wrinkles are likely to appear on the side of the packaging bag, causing the opening side of the packaging bag to change accordingly, so that the opening of the packaging bag deviates when it is aligned. As the feed gradually increases, this phenomenon will become more obvious, resulting in incomplete sealing when sealing. In addition, in other prior arts, a support plate is set. Before feeding, the support plate is placed in the packaging bag, and the support plate is moved to prop up the side of the packaging bag. Although this method can reduce the wrinkles on the side of the packaging bag when filling the feed, when the support plate is taken out after the feed is added, the packaging bag loses support, and the feed is completely in contact with the inner side of the packaging bag, which will cause the packaging bag to tilt or wrinkle. In addition, when the support plate contacts the inner side of the packaging bag to prop up the packaging bag, the side of the packaging bag will also wrinkle under the action of the support plate, which is inconvenient to seal the packaging bag later, affecting the sealing effect. Summary of the invention

[0005] The present invention provides a packaging device and method for producing fermented biological feed, aiming to solve the problem in the related art that when packaging feed, the packaging bag is prone to wrinkles, which affects the sealing.

[0029] After the airbag is separated from the packaging bag, the filling is completed, the airbag is retracted by pumping air through the air pipe, and the control sleeve cooperates with the connecting rod to retract the connecting rod.

[0030] The effect is that the airbag is inflated or deflated through the air tube one and the air tube two, the airbag is propped up to support the packaging bag during filling, and the airbag is deflated and retracted after the filling is completed, so that the opening of the packaging bag can be aligned and sealed after the filling is completed.

DETAILED DESCRIPTION

[0043] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0044] The invention discloses packaging equipment for producing fermented biological feed.

[0045] Reference Figure 1 The packaging equipment for fermented biological feed production includes a filling component 1, a conveying component 2 and a supporting component 3. The filling component 1 is installed on a frame 01. The conveying component 2 is configured as a belt conveyor for conveying the packaging bag 02 to the filling component 1. The filling component 1 is arranged above the conveying component 2 and is spaced apart from the conveying component 2. The supporting component 3 is arranged at the output end of the filling component 1.

[0046] During filling, the conveying component 2 conveys the packaging bag 02 to the filling component 1, and the filling component 1 puts the feed into the packaging bag 02. During filling, the supporting component 3 supports the packaging bag 02 to reduce the wrinkles on the side of the packaging bag 02 during filling, so as to facilitate the subsequent sealing process of the packaging bag 02.

[0047] Reference Figure 1 and Figure 2The filling assembly 1 includes an upper hopper 11 and a lower feeding pipe 12. The top of the upper hopper 11 is provided with an opening for adding feed. One end of the lower feeding pipe 12 is connected to the inside of the lower hopper through the bottom of the lower hopper, and the other end is vertically arranged toward the conveying assembly 2. The feed enters the packaging bag 02 through the upper hopper 11 and the lower feeding pipe 12 to fill the feed.

[0048] Reference Figures 2 to 4 The support assembly 3 includes a sleeve 31, an airbag 32, a connecting rod 33 and a driving member 34. The sleeve 31 is arranged at one end of the discharge tube 12 close to the packaging bag 02, and the sleeve 31 is slidably arranged on the discharge tube 12 along the vertical direction. The first end of the connecting rod 33 is connected to the sleeve 31, and the second end is connected to the airbag 32. The airbag 32 is arranged in a ring shape corresponding to the inner side of the packaging bag 02, and the outer side of the airbag 32 abuts against the inner side of the packaging bag 02. The driving member 34 is arranged on the frame 01, and the output end of the driving member 34 is connected to the sleeve 31.

[0049] Before filling, the sliding sleeve 31 drives the airbag 32 to move to the bottom of the packaging bag 02. When filling the feed, the driving member 34 drives the sliding sleeve 31 to move vertically upward. The movement of the sliding sleeve 31 drives the airbag 32 to move through the connecting rod 33. The movement of the airbag 32 props up the packaging bag 02. At the same time, the airbag 32 can fully contact the inner side of the packaging bag 02, and during the filling process, the airbag 32 gradually moves to stretch the packaging bag 02, further reducing the wrinkles on the side of the packaging bag 02, so as to facilitate the subsequent sealing of the packaging bag 02.

[0050] Reference Figures 2 to 4 The driving member 34 includes a motor 341 and a gear rod 342. The gear rod 342 is connected to the sleeve 31 and is arranged along the sliding direction of the sleeve 31. The motor 341 is arranged on the frame 01. The output end of the motor 341 is provided with a gear 343. The gear 343 is meshed with the gear rod 342. The motor 341 drives the gear rod 342 to move through the gear 343, thereby adjusting the position of the sleeve 31. In other embodiments, the driving member 34 can also be arranged as a cylinder, and the output end of the cylinder is connected to the sleeve 31 to adjust the position of the sleeve 31.

[0051] Reference Figures 2 to 4 In order to facilitate placing the airbag 32 in the packaging bag 02 to support the packaging bag 02, the connecting rod 33 is rotatably arranged on the sliding sleeve 31, and a rotating member (not shown in the figure) is arranged at the connection between the connecting rod 33 and the sliding sleeve 31. The rotating member is arranged as a torsion spring, and the torsion spring is used to drive the end of the connecting rod 33 close to the airbag 32 to rotate and unfold in a direction away from the sliding sleeve 31. A control member 4 is arranged on the sliding sleeve 31, and the control member 4 is connected to the connecting rod 33 to drive the connecting rod 33 to rotate and retract.

[0052] After the airbag 32 moves into the packaging bag 02 , the control member 4 is separated from the connecting rod 33 , and the connecting rod 33 rotates under the action of the rotating member, and at the same time drives the airbag 32 to open to support the packaging bag 02 .

[0053] Reference Figure 4 and Figure 5 The control member 4 includes a pull rod 41 and a control sleeve 42. The control sleeve 42 is slidably arranged outside the sliding sleeve 31, and the control sleeve 42 slides on the sliding sleeve 31 along the vertical direction. The control sleeve 42 is arranged above the connecting rod 33. The control sleeve 42 is provided with an opening on the side close to the connecting rod 33. The inner wall of the control sleeve 42 is spaced apart from the sliding sleeve 31. The pull rod 41 is arranged along the sliding direction of the sliding sleeve 31. The first end of the pull rod 41 is connected to the control sleeve 42, and the second end is bent toward the direction of the discharge pipe 12. A control groove 121 is opened on the side of the discharge pipe 12, and the bent end of the pull rod 41 is slidably arranged in the control groove 121.

[0054] In the initial state, the control sleeve 42 is outside the pull rod 41, and the inner wall of the control sleeve 42 abuts against the pull rod 41. At this time, the pull rod 41 is in the retracted state. After the sliding sleeve 31 moves into the packaging bag 02, the bent end of the pull rod 41 moves to the end of the control groove 121 and abuts against the inner wall of the control groove 121. The sliding sleeve 31 continues to move, and the control sleeve 42 moves relative to the sliding sleeve 31 until the control sleeve 42 is separated from the pull rod 41. After the pull rod 41 is separated from the control sleeve 42, the rotating member drives the connecting rod 33 to unfold. After the filling is completed, the sliding sleeve 31 moves in the opposite direction, and the bent end of the pull rod 41 moves to abut against the inner wall of the end of the control groove 121 away from the ground. The sliding sleeve 31 continues to move, and the control sleeve 42 moves relative to the sliding sleeve 31. The control sleeve 42 drives the connecting rod 33 to rotate until the connecting rod 33 abuts against the inner wall of the control sleeve 42, and the connecting rod 33 is retracted.

[0055] Reference Figures 2 to 4 A plurality of connecting rods 33 are arranged around the sliding sleeve 31, and the ends of the plurality of connecting rods 33 close to the sliding sleeve 31 are arranged in the same horizontal plane, that is, the rotating ends of the connecting rods 33 are arranged in the same plane. The airbag 32 can be folded or unfolded through the plurality of connecting rods 33, and the plurality of connecting rods 33 can be driven to rotate and fold at the same time when the control sleeve 42 is moved.

[0056] Reference Figure 4 and Figure 6, a guiding arc surface 321 is arranged on the outside of the airbag 32, and the guiding arc surface 321 is arranged near the top of the airbag 32, so that the airbag 32 can unfold the side of the packaging bag 02 and stretch the packaging bag 02 when it moves. Here, the abutment force between the airbag 32 and the inner side of the packaging bag 02 can only prop up the side of the packaging bag 02. When the airbag 32 moves in the vertical direction, part of the feed has been loaded into the packaging bag 02. Under the action of the gravity of this part of the feed, the airbag 32 will not drive the packaging bag 02 to move along with it in the vertical direction when it moves, that is, the friction between the airbag 32 and the inner side of the packaging bag 02 is less than the gravity of the loaded feed. In addition, the air pressure inside the airbag 32 can be adjusted according to the actual packaging needs to ensure the stability of the packaging bag 02.

[0057] Reference Figure 4 and Figure 6 The middle rod 5 is rotatably arranged at one end of the connecting rod 33 close to the airbag 32, and the connecting rod 33 is connected to the airbag 32 through the middle rod 5. An auxiliary rod 6 is arranged on the sliding sleeve 31, and the two ends of the auxiliary rod 6 are rotatably connected to the sliding sleeve 31 and the middle rod 5 respectively. The auxiliary rod 6 is arranged parallel to the connecting rod 33 and spaced apart, and the middle rod 5 is arranged parallel to the sliding sleeve 31, that is, the auxiliary rod 6, the connecting rod 33, the middle rod 5 and the sliding sleeve 31 are surrounded to form a parallelogram structure, so that the middle rod 5 remains in a vertical state when the connecting rod 33 rotates, so as to retract or deploy the airbag 32.

[0058] Air pipe 1 7 and air pipe 2 8 are arranged between auxiliary rod 6 and connecting rod 33. Air pipe 1 7 and air pipe 2 8 are respectively connected with air bag 32, and the ends of air pipe 1 7 and air pipe 2 8 away from air bag 32 pass through sliding sleeve 31 and extend to frame 01. Air pipe 1 7 and air pipe 2 8 are both connected with air pump. Air pipe 1 7 is used to inflate air bag 32 to unfold air bag 32, and air pipe 2 8 is used to pump air out of air bag 32 to retract air bag 32. After air bag 32 is placed in packaging bag 02, air pipe 1 7 is inflated to open air bag 32. After filling is completed, air pipe 2 8 is pumped to retract air bag 32 so that air bag 32 can be retracted with connecting rod 33.

[0059] Reference Figure 6 and Figure 7, the trachea 1 7 and the trachea 2 8 are both arranged through the middle rod 5, and a middle groove 51 is provided in the middle rod 5, and the middle groove 51 is connected with the trachea 1 7 and the trachea 2 8. A baffle 9 is slidably provided in the middle groove 51, and a through hole 91 is provided on the baffle 9, and the baffle 9 is used to block the trachea 1 7 and the trachea 2 8. After the through hole 91 moves to the corresponding position, the corresponding pipeline is opened. An elastic member 511 is provided in the middle groove 51, and the elastic member 511 is set as a spring. The spring and the baffle 9 are connected to drive the baffle 9 to move toward the outside of the middle groove 51. A push rod 92 is provided on the middle rod 5, and the push rod 92 slides horizontally toward the packaging bag 02. The push rod 92 is provided with an inclined surface 921 that cooperates with the push rod 92. When the push rod 92 moves in the direction away from the packaging bag 02, the baffle 9 is driven to move in the direction toward the middle groove 51 through the inclined surface 921.

[0060] Reference Figure 6 and Figure 7 In the initial state, the through hole 91 corresponds to the trachea 2 8, and the trachea 1 7 is in a closed state. After the airbag 32 moves into the packaging bag 02, the connecting rod 33 rotates and opens to drive the push rod 92 to abut against the inner side of the packaging bag 02. The movement of the push rod 92 drives the baffle 9 to move, so that the through hole 91 corresponds to the trachea 1 7 to open the trachea 1 7 and close the trachea 2 8, and the airbag 32 is inflated through the trachea 1 7 to open the airbag 32. As the filling is completed, the airbag 32 moves to the outside of the packaging bag 02, and the push rod 92 is separated from the packaging bag 02. The baffle 9 drives the through hole 91 to correspond to the trachea 2 8 again under the action of the spring, and the airbag 32 is evacuated through the trachea 2 8 to retract the airbag 32, and at the same time, it is convenient to support the packaging bag 02 again.

Through multiple horizontally arranged discharge ports 311, the feed can be uniformly fed into the packaging bag 02, so that the feed filling is more uniform. In addition, a power member 312 and a paddle 313 are arranged at one end of the sleeve 31 close to the discharge port 311. The power member 312 can be set as a motor 341, and the motor 341 is arranged on the sleeve 31. The paddle 313 is connected to the output end of the power member 312. Multiple paddles 313 are arranged around the sleeve 31, and the side of the paddle 313 away from the motor 341 is tilted away from the rotation direction thereof. The motor 341 drives the paddle 313 to rotate, and the paddle 313 is used to push the feed uniformly to various places in the packaging bag 02, so that the feed filling is more uniform.

[0062] The implementation principle of the present invention is as follows: the sliding sleeve 31 moves into the packaging bag 02, the connecting rod 33 drives the airbag 32 to open and inflate, and the airbag 32 supports the packaging bag 02 after it is unfolded. During filling, the sliding sleeve 31 drives the airbag 32 to move accordingly, so that the airbag 32 supports the packaging bag 02 and stretches the packaging bag 02 in the vertical direction at the same time. The feed is filled under the airbag 32, reducing the phenomenon of wrinkles in the packaging bag 02 during filling, thereby reducing the deviation of the opening of the packaging bag 02, so as to facilitate subsequent sealing.
