AI Technical Summary
Existing feed baling devices lack stability when clamping packaging bags, making them prone to slippage.
The system uses an electromagnet plate to attract an iron ring and an arc-shaped clamping plate, which is then pushed by a cylinder. Combined with the repulsive force between the electromagnet blocks and magnets in the first and second clamping blocks, the packaging bag is pressed into the clamping groove by the pressing block, thus enhancing the clamping stability.
It effectively prevents the packaging bag from slipping, improves the stability and fit of the clamp, and ensures the stability of the packaging bag during the packaging process.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed processing technology, specifically a packaging device for feed production. Background Technology
[0002] Feed processing is the process of producing standardized feed products that meet the nutritional needs of different animals (pigs, chickens, cattle, aquatic animals, etc.) at different growth stages by subjecting various raw materials (such as grains, protein sources, minerals, vitamins, etc.) to a series of physical, chemical, or biological treatments. Its core objectives are to ensure nutritional balance, improve feed utilization, reduce breeding costs, and ensure feed safety and hygiene.
[0003] Existing feed packaging devices require packaging after production and processing. These devices typically use side clamps to hold the packaging bag at the end of the hopper, allowing feed to flow into the bag. However, relying solely on a cylinder to tilt and push the clamps to hold the bag results in inconsistent clamping stability and a tendency for slippage. Therefore, we propose a new packaging device for feed production. Utility Model Content
[0004] The purpose of this invention is to provide a packaging device for feed production, which solves the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging device for feed production, comprising a hopper, a guide tube fixedly connected to the tail end of the hopper, a fixed frame fixedly fitted on the outer wall of the guide tube, movable handles hinged to both sides of the two side walls of the fixed frame, an arc-shaped clamping plate fixedly connected between the two movable handles on the same side for pressing the packaging bag, an electromagnet plate fixedly connected to the inner side wall of the arc-shaped clamping plate, an iron ring fixedly fitted on the lower side of the outer wall of the guide tube, a cylinder hinged to the outer wall of the arc-shaped clamping plate, and the other end of the cylinder hinged to the outer wall of the hopper via a hinge seat.
[0006] By adopting the above technical solution, the packaging bag is first placed on the end of the conduit, and then the cylinder is activated to push the arc-shaped clamping plate to move, thereby pressing the packaging bag tightly against the outer wall of the conduit. At the same time, after the arc-shaped clamping plate presses the packaging bag tightly, the electromagnet plate can be attracted to the outer wall of the iron ring, which helps to improve the pressing effect on the packaging bag and thus helps to avoid slippage.
[0007] In a preferred embodiment of this utility model, one of the arc-shaped clamping plates has a first clamping block fixedly connected to both ends, and the other arc-shaped clamping plate has a second clamping block fixedly connected to both ends. The first clamping block has a hollow structure, and a matching movable block is provided in the inner cavity of the first clamping block. A plurality of evenly distributed pressure blocks are fixedly connected to one side wall of the movable block, and the pressure blocks movably pass through the first clamping block. A magnet is fixedly installed on the other side wall of the movable block, and an electromagnet block is fixedly installed on one side wall of the inner cavity of the first clamping block.
[0008] By adopting the above technical solution, when clamping the packaging bag, the first clamping block and the second clamping block can clamp the packaging bag. Then, when clamping, the electromagnet block is energized, which generates a repulsive force on the magnet, thereby pushing the movable block to move outward, so that the pressure block applies pressure to the packaging bag, which helps to improve the clamping stability.
[0009] In a preferred embodiment of the present invention, a pressure groove is provided on the outer wall of the second clamping block corresponding to the pressure block.
[0010] By adopting the above technical solution, the setting of the pressure groove enables the pressure block to press the packaging bag into the pressure groove when applying pressure to the packaging bag, thereby improving the stability of the packaging bag after applying pressure.
[0011] In a preferred embodiment of this utility model, springs are fixedly connected to both sides of one side wall of the movable block, and the outer ends of the springs are fixedly connected to the inner wall of the inner cavity of the first clamping block.
[0012] By adopting the above technical solution, when the electromagnet block is de-energized, the spring can exert a pulling force on the movable block, thereby causing the movable block to reset.
[0013] In a preferred embodiment of this utility model, the electromagnet plate is an arc-shaped plate, and its inner sidewall is fixedly glued with a suitable rubber pad.
[0014] By adopting the above technical solution, the rubber pad can increase the fit of the packaging bag under pressure, thereby improving stability.
[0015] In a preferred embodiment of this utility model, the outer wall of the iron ring is provided with anti-slip texture.
[0016] By adopting the above technical solution, the anti-slip texture increases the friction with the packaging bag, further improving the stability of the packaging bag clamping.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] The packaging device for feed production disclosed in this application uses an electric push rod to drive an arc-shaped clamping plate to clamp the outer wall of a guide tube. At the same time, it can use an electromagnet plate to attract the iron ring surface, thereby improving the clamping effect on the packaging bag and helping to avoid slippage.
[0019] When the packaging bag is clamped by the first clamping block and the second clamping plate, the packaging bag is pressed into the pressure groove by using the electromagnet block to push the pressure block, thereby increasing the contact effect with the packaging bag, which helps to improve the clamping stability of the packaging bag and thus helps to avoid slippage.

[0028] Please see Figure 1-3 This utility model provides a technical solution: a packaging device for feed production, including a hopper 1, a conduit 11 fixedly connected to the tail end of the hopper 1, a fixed frame fixedly fitted on the outer wall of the conduit 11, movable handles 25 hinged to both sides of the two side walls of the fixed frame, an arc-shaped clamping plate 2 fixedly connected between the two movable handles 25 on the same side for pressing the packaging bag, an electromagnet plate 24 fixedly connected to the inner side wall of the arc-shaped clamping plate 2, an iron ring 12 fixedly fitted on the lower side of the outer wall of the conduit 11, a cylinder 21 hinged to the outer wall of the arc-shaped clamping plate 2, and the other end of the cylinder 21 hinged to the outer wall of the hopper 1 through a hinge seat 22.
[0029] It should be understood that in actual use, the packaging bag is first placed on the end of the conduit 11, and then the cylinder 21 is activated to push the arc-shaped clamp 2 to move, thereby pressing the packaging bag against the outer wall of the conduit 11. At the same time, after the arc-shaped clamp 2 presses the packaging bag, the electromagnet plate 24 can be attracted to the outer wall of the iron ring 12, which helps to improve the pressing effect on the packaging bag and thus helps to avoid slippage.
[0030] Furthermore, the outer wall of the iron ring 12 is provided with anti-slip texture. The anti-slip texture increases the friction with the packaging bag, thereby further improving the stability of the packaging bag clamping.
[0031] Furthermore, the electromagnet plate 24 is an arc-shaped plate, and its inner wall is fixedly glued with a suitable rubber pad. The setting of the rubber pad can increase the fit of the packaging bag, thereby helping to improve stability.
[0032] like Figure 1 and 2 As shown; one of the arc-shaped clamping plates 2 has a first clamping block 3 fixedly connected to both ends, and the other arc-shaped clamping plate 2 has a second clamping block 23 fixedly connected to both ends. The first clamping block 3 is a hollow structure. The inner cavity of the first clamping block 3 is provided with a matching movable block 31. A plurality of evenly distributed pressure blocks 32 are fixedly connected to one side wall of the movable block 31. The pressure blocks 32 movably pass through the first clamping block 3. A magnet 35 is fixedly installed on the other side wall of the movable block 31. An electromagnet block 33 is fixedly installed on one side wall of the inner cavity of the first clamping block 3.
[0033] It should be understood that in actual use, when clamping the packaging bag, the first clamping block 3 and the second clamping block 23 can clamp the packaging bag. Then, when clamping, the electromagnet block 33 is energized, which can generate a repulsive force on the magnet 35, thereby pushing the movable block 31 to move outward, so that the pressure block 32 applies pressure to the packaging bag, which helps to improve the clamping stability.
[0034] Furthermore, the outer wall of the second clamping block 23 is provided with a pressure groove corresponding to the pressure block 32. The setting of the pressure groove allows the pressure block 32 to press the packaging bag into the pressure groove when it applies pressure to the packaging bag, thereby improving the stability of the packaging bag after applying pressure.
[0035] Furthermore, springs 34 are fixedly connected to both sides of one side wall of the movable block 31, and the outer end of the spring 34 is fixedly connected to the inner wall of the inner cavity of the first clamping block 3.
[0036] It should be understood that when the electromagnet block 33 is de-energized, the spring 34 can exert a pulling force on the movable block 31, thereby causing the movable block 31 to reset.
[0037] Furthermore, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
