TECHNICAL FIELD

[0001] The utility model relates to fertilizer production device technical field especially relates to a fertilizer packaging machine bag conveying device. BACKGROUND

[0002] In the current vigorous development of agricultural production, the use of fertilizer is increasing day by day, and the importance of fertilizer packaging link is increasingly prominent. As the key equipment in the fertilizer production process, the performance of the fertilizer packaging machine directly affects the efficiency and quality of the fertilizer packaging. And the bag conveying device as the core component of the fertilizer packaging machine, undertakes the important task of conveying the packaging bag accurately and efficiently to the material injection packaging station. The existing bag conveying device is difficult to achieve the ideal state in terms of conveying speed and stability, and in the high-speed production environment, the improvement of conveying speed is often accompanied by the decline of stability, thereby affecting the production efficiency of the packaging machine. SUMMARY

[0003] In view of the above problems, the purpose of the utility model is to design a fertilizer packaging machine bag conveying device, which has high conveying efficiency and stability in high-speed production environment.

[0004] The purpose of the utility model is achieved by the following technical scheme:

[0005] A fertilizer packaging machine bag conveying device is designed, which comprises a storage and clamping mechanism for temporarily storing packaging bags, and a clamping mechanism for clamping packaging bags from the storage and clamping mechanism. The storage and clamping mechanism comprises a rack, a storage platform arranged on the rack, and a conveying unit. The storage platform comprises a storage position and a clamping position. An adjustable clamping baffle is arranged between the storage position and the clamping position. The clamping baffle and the storage platform have a conveying gap through which the packaging bag can pass. The conveying unit can sequentially transfer the packaging bag from the storage position to the clamping position through the conveying gap.

[0006] The fertilizer packaging machine bag conveying device designed in the scheme is used to convey the fertilizer packaging bag to the clamping carrier of the packaging machine for filling fertilizer particles. Through the cooperative design of the storage and clamping mechanism and the clamping mechanism, efficient and stable conveying of the fertilizer packaging bag is realized. The storage and clamping mechanism adopts a double-position design, and the storage position and the clamping position are separated. The storage position can pre-store a batch of packaging bags, and the clamping position can supply the clamping mechanism in real time, realizing uninterrupted feeding. The storage position supports manual or automatic bag replenishment, and the clamping baffle isolates the storage position and the clamping position, avoiding downtime waiting. At the same time, the adjustable conveying gap between the clamping baffle and the storage platform is usually designed to be slightly larger than the thickness of a single layer of packaging bags, which can effectively separate the stacked packaging bags and avoid multi-bag adhesion or accumulation, ensuring continuous conveying of single bags. By adjusting the height of the clamping baffle to adjust the conveying gap, packaging bags of different thicknesses can be compatible, adapting to diversified production needs.

[0007] Further, the storage platform is provided with two positioning plates in parallel, and the packaging bag is arranged between the two positioning plates.

[0008] The storage platform is provided with two positioning plates in parallel, and the storage platform is provided with a continuous guide structure extending from the storage position to the clamping position, so that the positioning accuracy and the conveying stability of the packaging bag are optimized. The parallel positioning plates form a continuous guide rail from the storage position to the clamping position, so that the packaging bag is forced to move along a straight path, and lateral deviation caused by inertia or vibration during conveying is avoided.

[0009] Further, the opposite sides of the two positioning plates are provided with bearing guide rails, and the two side edges of the packaging bag in the width direction are arranged on the bearing guide rails.

[0010] The bearing guide rails are arranged on the sides of the positioning plates, and the two side edges of the packaging bag are directly borne, so that a stable and low-resistance conveying channel is constructed, and the positioning accuracy and the running reliability of the packaging bag during storage to clamping are significantly improved. The bearing guide rail adopts a smooth surface structure, which reduces the contact resistance between the side edge of the packaging bag and the guide rail, and avoids the surface wear of the packaging bag.

[0011] Further, the spacing between the two positioning plates is adjustable.

[0012] The spacing between the positioning plates is adjusted by a slide rail or a screw rod mechanism, which is suitable for packaging bags of different widths, so as to improve the compatibility of multiple specifications. The spacing between the positioning plates is slightly larger than the width of the packaging bag, which not only limits the lateral displacement of the packaging bag, but also avoids the problem of bag stacking and jamming caused by extrusion.

[0013] Further, the conveying unit comprises a first conveying wheel set, a second conveying wheel set, and a driving member for driving the first conveying wheel set and the second conveying wheel set to rotate synchronously, the first conveying wheel set is located at the storage position, and the second conveying wheel set is located at the clamping position.

[0014] Through the synchronous driving design of the first conveying wheel set and the second conveying wheel set, the precise and efficient conveying of the fertilizer packaging bag from storage to clamping is realized. The first conveying wheel set is provided with a plurality of coarse-toothed rubber wheels, which are uniformly distributed at the storage position of the storage platform to enhance the carding capacity, and is responsible for stably outputting the packaging bag from the storage area and bearing the initial traction function. The second conveying wheel set adopts a silica gel coated smooth surface wheel to realize soft stopping of the packaging bag, so as to ensure the positioning accuracy of the packaging bag at the end and facilitate the clamping of the clamping mechanism.

[0015] Further, the first conveying wheel set and the second conveying wheel set are arranged below the storage platform, the storage platform is provided with wheel holes corresponding to the first conveying wheel set and the second conveying wheel set, and the outer circumferential surface of the first conveying wheel set and the second conveying wheel set passes through the wheel holes and is in contact with the lower surface of the packaging bag.

[0016] By placing the first and second conveying wheel sets below the storage platform, the vertical space is utilized to reduce the overall height of the device.

[0017] Further, the conveying unit further comprises a third conveying wheel set located at the clamping position, which is arranged above the storage platform and corresponds to the second conveying wheel set, and the third conveying wheel set is in contact with the upper surface of the packaging bag.

[0018] By adding a third conveying wheel set, the double-sided clamping mechanism significantly optimizes the conveying performance. The second and third conveying wheel sets form an upper and lower clamping structure, so that the packaging bag is subjected to vertical positive pressure at the clamping position, avoiding slipping caused by single-sided friction. At the same time, the double-sided contact clamping makes the end of the packaging bag flat on the conveying plane, simultaneously improving the end positioning accuracy, facilitating the clamping mechanism to grab.

[0019] Further, the end of the storage platform near the clamping mechanism is provided with a clamping avoidance position.

[0020] The clamping avoidance position adopts a trapezoidal or semicircular notch to ensure that the clamping mechanism has no mechanical collision risk when grabbing the packaging bag, and the efficiency and safety of the clamping action are realized through physical space optimization.

[0021] Further, the clamping mechanism comprises a support frame, a connecting rod rotatably arranged on the support frame, and a clamping jaw arranged at the end of the connecting rod, the connecting rod is provided with a clamping jaw driving member for driving the clamping jaw to open and close, and the support frame is provided with a connecting rod driving member for driving the connecting rod to rotate.

[0022] When the packaging bag is conveyed to the clamping position of the storage platform, the connecting rod driving member drives the connecting rod to rotate and moves the clamping jaw to the clamping avoidance position, which is opposite to the clamping position of the end of the packaging bag, then the clamping jaw driving member drives the clamping jaw to close to clamp the packaging bag, and then the connecting rod driving member drives the connecting rod to rotate and moves the clamping jaw to the bag feeding position of the packaging machine. The connecting rod mechanism converts the linear motion of the clamping jaw into the curved opening and closing trajectory of the clamping jaw, realizing the horizontal and vertical synchronous movement of the clamping jaw after clamping the packaging bag, and improving the clamping motion efficiency.

[0023] Further, the clamping jaw comprises a fixed clamping jaw fixedly arranged on the connecting rod and a movable clamping jaw rotatably arranged on the connecting rod, and the output end of the clamping jaw driving member is connected with the movable clamping jaw.

[0024] The fixed clamping jaw is fixed on the connecting rod by a fastener, serving as a reference point for clamping action, and the movable clamping jaw is fixed on the connecting rod by a bearing and can rotate around the shaft, responsible for dynamic clamping or releasing the packaging bag. The clamping jaw driving member adopts a driving cylinder to control the opening and closing of the clamping jaw by pushing and pulling. The separation design of the fixed clamping jaw and the movable clamping jaw has the characteristics of low cost and easy maintenance.

[0025] Compared with the prior art, the fertilizer packaging machine bag conveying device has the beneficial effects that

[0026] The fertilizer packaging machine bag conveying device is used for conveying the fertilizer packaging bag to the clamping carrier of the packaging machine to fill the fertilizer particles, and through the cooperative design of the storage card separating mechanism and the clamping mechanism, efficient and stable conveying of the fertilizer packaging bag is realized.

The preferred embodiments of the utility model are shown in the drawings. However, the utility model can be realized in many different forms, and is not limited to the embodiments described herein.

[0033] As Figures 1 to 3 The embodiment provides a fertilizer packaging machine bag conveying device, which comprises a storage and separating mechanism 1 for temporarily storing packaging bags and a clamping mechanism 2 for clamping the packaging bags from the storage and separating mechanism 1, the storage and separating mechanism 1 comprises a rack 11, a storage platform 12 arranged on the rack and a conveying unit 13, the storage platform 12 comprises a storage position 121 and a clamping position 122, an adjustable separating baffle 14 is arranged between the storage position 121 and the clamping position 122, the separating baffle 14 and the storage platform 12 are provided with a conveying gap 141 for the packaging bags to pass through, and the conveying unit 13 can sequentially transfer the packaging bags from the storage position 121 to the clamping position 122 through the conveying gap 141.

[0034] The fertilizer packaging machine bag conveying device provided by the embodiment is used for conveying the fertilizer packaging bags to the clamping carrier of a packaging machine to fill the fertilizer particles, and through the cooperative design of the storage and separating mechanism 1 and the clamping mechanism 2, the efficient and stable conveying of the fertilizer packaging bags is realized. The storage and separating mechanism 1 adopts a double-position design, the storage position 121 and the clamping position 122 are separated, seamless connection is realized through the conveying unit 13, the storage position 121 can pre-store the packaging bags in batches, the clamping position 122 can supply the clamping mechanism 2 in real time, and uninterrupted feeding is realized. The storage position 121 supports manual or automatic bag replenishment, the separating baffle 14 isolates the storage position 121 and the clamping position, and downtime waiting is avoided. Meanwhile, the adjustable conveying gap between the separating baffle 14 and the storage platform 12 is usually designed to be slightly larger than the thickness of a single layer of packaging bags, which can effectively separate the stacked packaging bags and avoid multi-bag adhesion or accumulation, thereby guaranteeing the continuous conveying of single bags. By adjusting the height of the separating baffle 14 to adjust the conveying gap, packaging bags with different thicknesses can be compatible, and diversified production requirements can be met.

[0035] As Figure 1 and Figure 2As shown, the storage platform 12 is provided with two positioning plates 15 in parallel, and the packaging bags are placed between the two positioning plates 15, and the positioning plates 15 extend from the storage position 121 to the clamping position 122. Through the continuous guide structure extending from the storage position 121 to the clamping position 122, the positioning accuracy and conveying stability of the packaging bags are optimized. The parallel positioning plates 15 form a continuous guide track from the storage position 121 to the clamping position 122, forcing the packaging bags to move along a straight path, avoiding lateral deviation caused by inertia or vibration during conveying. In addition, the height of the positioning plate 15 of the storage position 121 is greater than the height of the stacked packaging bags, so as to limit the stacked packaging bags and prevent tilting.

The opposite sides of the two positioning plates 15 are provided with bearing guide rails 151, and the two side edges of the packaging bags in the width direction are placed on the bearing guide rails 151. The bearing guide rails 151 are arranged on the side surfaces of the positioning plates 15, which directly bear the two side edges of the packaging bags, and build a stable and low-resistance conveying channel, which significantly improves the positioning accuracy and running reliability of the packaging bags during storage to clamping. The bearing guide rails 151 adopt a smooth surface structure, which reduces the contact resistance between the side edges of the packaging bags and the bearing guide rails 151, and avoids the surface wear of the packaging bags. The spacing of the positioning plates 15 is adjusted by a slide rail or a screw rod mechanism, which is suitable for packaging bags of different widths, so as to improve the compatibility of multiple specifications. The spacing of the positioning plates 15 is slightly greater than the width of the packaging bags, which not only limits the lateral displacement of the packaging bags, but also avoids the problem of stacking bag jamming caused by extrusion.

By arranging the first conveying wheel set 131 and the second conveying wheel set 132 below the storage platform 12, the overall height of the equipment is reduced by using the vertical space. The first conveying wheel set 131 and the second conveying wheel set 132 are designed to be driven synchronously, realizing accurate and efficient conveying of the fertilizer packaging bag from storage to clamping.
