Description

Technical Field

[0001] This utility model relates to the field of feed production technology, specifically to a feed quantitative packaging device for feed production. Background Technology

[0002] In the feed production process, the finished feed is usually filled into feed bags using quantitative packaging equipment with the aid of a weighing device. Quantitative packaging equipment is generally divided into two types: one is packaging equipment equipped with a dynamic conveying weighing device and an automatic sewing machine for continuous filling and sewing operations; the other is a separate packaging equipment equipped with a fixed weighing device for quantitative filling. After the feed is filled, the workers unload the feed, and other workers use a hand-held sewing machine to sew the feed bags. Because the filled feed bags are relatively heavy, the entire process is handled by the workers, which is labor-intensive. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This utility model provides a quantitative packaging equipment for feed production. After filling, under the action of the second motor and the lead screw, the moving frame moves and adjusts on the lead screw, so that the packaging bag containing feed moves between the clamps. Under the action of the first cylinder, the clamps are pushed to hold and fix the middle section of the packaging bag. The packaging bag containing feed is rotated and transferred by the unloading adjustment frame.

[0027] Figures 1-5 The diagram shown is an overall structural schematic of one embodiment of a feed quantitative packaging device for feed production according to this utility model. Please refer to [link / reference]. Figures 1-5 This embodiment of a feed production quantitative packaging device includes a frame 1, a conveying pipe 3 fixedly installed at the upper end of the frame 1, a drive shaft 4 rotatably connected to the inner wall of the conveying pipe 3, a first spiral blade 6 and a second spiral blade 7 fixedly connected to the outer ring of the drive shaft 4, the first spiral blade 6 being located behind the second spiral blade 7, a discharge pipe 8 fixedly connected to the discharge port of the conveying pipe 3, a weighing adjustment frame 10 being installed below the discharge pipe 8, a discharge adjustment frame 9 being installed on the left side of the weighing adjustment frame 10, and a support bracket 11 being installed on both the front and rear sides of the weighing adjustment frame 10.

[0028] The feed port of the conveying pipe 3 is fixedly connected to the hopper 2, and the rear end of the drive shaft 4 passes through the conveying pipe 3 and is connected to the output shaft of the first motor 5.

[0029] Feed in hopper 2 enters conveying pipe 3, and is driven by first motor 5 to rotate drive shaft 4, thereby pushing and conveying feed under the action of first spiral blade 6 and second spiral blade 7. The first spiral blade 6 has a large pitch and the second spiral blade 7 has a small pitch to reduce material accumulation at the end. The first motor 5 is controlled by frequency converter to achieve stepless speed regulation and automatic switching between coarse and fine feeding. The frequency converter model is Mitsubishi FR-D800. Coarse feeding: high speed filling to 90%~95% of the target weight to quickly complete most of the feeding. Fine feeding: slow down to replenish to close to 100% to avoid overshoot and improve filling accuracy. PID closed-loop control: compare the weight feedback from the sensor with the target value in real time and dynamically adjust the speed. This part of the control is a prior art structure. A pneumatic butterfly valve is installed between the discharge port of conveying pipe 3 and discharge pipe 8 to cut off the material flow when the spiral conveying stops.

[0030] The unloading adjustment frame 9 includes a rotating shaft 901 that is rotatably connected to the upper end of the unloading adjustment frame 9. A supporting rotating frame 902 is fixedly connected to the upper end of the rotating shaft 901. A clamping adjustment frame 903 is connected to the right side of the supporting rotating frame 902. A first cylinder 904 is fixedly and through the side wall of the clamping adjustment frame 903. A clamp 905 is fixedly connected to the telescopic end of the first cylinder 904. A silicone layer is installed on the inner clamping surface of the clamp 905.

[0031] The unloading adjustment frame 9 is equipped with a drive motor. The drive motor rotates through a reduction gearbox and a rotating shaft 901, thereby driving the support frame 902 to rotate. The first cylinder 904 pushes the clamp 905 to clamp and hold the middle section of the packaging bag containing feed, thereby rotating and transferring the package bag for unloading. The silicone layer enhances the clamping stability of the packaging bag and also protects the packaging bag. Depending on the situation, the clamping adjustment frame 903 can be moved up and down on the support frame 902. The movement adjustment of the clamping adjustment frame 903 is used through a cylinder or lead screw transmission structure. The clamping adjustment frame 903 is slidably connected to the support frame 902 through a slide rail to enhance stability during movement. It is controlled by a motion controller. The motion controller model is Panasonic MINASA6, and the main controller model is Mitsubishi FX5U.

[0032] The weighing adjustment frame 10 includes a lead screw 1001 rotatably connected to the inner wall of the weighing adjustment frame 10. The right side of the lead screw 1001 passes through the weighing adjustment frame 10 and is connected to the output shaft of the second motor 1002. A movable frame 1003 is provided through the lead screw 1001, and a weighing device 1004 is provided at the upper end of the movable frame 1003.

[0033] The weighing device 1004 is used for quantitative weighing during feed packaging and filling. Under the action of the second motor 1002 and the lead screw 1001, the moving frame 1003 moves and adjusts on the lead screw 1001, so that the packaging bag containing the feed moves between the clamps 905.

[0034] The support bracket 11 includes a second cylinder 1101 fixedly disposed through the side wall of the support bracket 11, and a limit baffle 1102 is fixedly connected to the telescopic end of the second cylinder 1101.

[0035] The second cylinder 1101 pushes the limiting baffle 1102 to move and adjust, so that the limiting baffle 1102 limits and blocks the packaging bag but does not contact it, thus protecting the packaging bag during movement.

[0036] The support bracket 11 also includes a third cylinder 1103 fixedly disposed through the side wall of the support bracket 11. The third cylinder 1103 is disposed above the second cylinder 1101. The telescopic end of the third cylinder 1103 is fixedly connected to a connecting frame 1104. The top inner side of the connecting frame 1104 is movably connected to a spreading claw 1105. One side of the spreading claw 1105 is hinged to a fourth cylinder 1106 through a first hinge seat. The end of the fourth cylinder 1106 away from the spreading claw 1105 is hinged to the top inner side of the connecting frame 1104 through a second hinge seat.

[0037] The third cylinder 1103 drives the connecting frame 1104 to adjust, and the opening claw 1105 is used to open the packaging bag to facilitate filling and receiving. When the opening of the packaging bag is released, the fourth cylinder 1106 pushes the opening claw 1105 to rotate and tilt, so that the opening claw 1105 can be released from the opening operation of the packaging bag. Then, the third cylinder 1103 drives the connecting frame 1104 to adjust and pull the opening claw 1105 back. The contact surface between the opening claw 1105 and the packaging bag is provided with a silicone layer for protection when the packaging bag is opened.

[0038] Combination Figures 1-5 The specific operation of a feed quantitative packaging device for feed production according to this embodiment is as follows: The operator, positioned to the right of the weighing and adjusting frame 10, feeds the packaging bag. The third cylinder 1103 drives the connecting frame 1104 to adjust, and the opening claw 1105 is used to open the packaging bag for easy filling and receiving. The first motor 5 drives the transmission shaft 4 to rotate, thereby pushing and conveying the feed under the action of the first spiral blade 6 and the second spiral blade 7. The feed falls into the packaging bag through the discharge pipe 8. The weighing device 1004 weighs the feed in the packaging bag in real time. Once the specified weight is reached, the spiral conveying stops. Under the action of the fourth cylinder 1106, the opening claw 1105 is pushed to rotate and tilt, facilitating the opening claw 1105 to disengage from the opening operation of the packaging bag. Then, the connecting frame 1104 is adjusted by the third cylinder 1103, and the spreading claw 1105 is pulled back. The limiting baffle 1102 is moved and adjusted by the second cylinder 1101, so that the limiting baffle 1102 limits and blocks the packaging bag but does not contact it, thus protecting the packaging bag during movement. Under the action of the second motor 1002 and the lead screw 1001, the moving frame 1003 moves and adjusts on the lead screw 1001, so that the packaging bag containing feed moves between the clamps 905. The clamps 905 are clamped and held in the middle section of the packaging bag containing feed by the first cylinder 904. The unloading adjustment frame 9 is equipped with a drive motor. The drive motor rotates through the reduction gear box and the rotating shaft 901, thereby driving the supporting rotating frame 902 to rotate and unload.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
