Description

Technical Field

[0001] The utility model relates to the technical field of secondary packaging, in particular to a secondary packaging blanking and bag dragging mechanism. Background Art

[0002] With the rapid development of the automation industry, secondary packaging is increasingly used in agricultural seed packaging. However, due to the limitations of the packaging machine itself and the packaging speed, small bags of materials need to fall from a higher silo into the secondary packaging woven bag.

[0003] However, there is no buffer mechanism between the silo and the bottom receiving plate, which causes the small bags of materials to break due to their own gravity when they fall into the woven bags, causing the materials to spill, increasing the failure rate of large bags. When the materials spill, the subsequent bag sewing and robot stacking operations will also be suspended. At the same time, the small bags of materials cannot be guaranteed to be flat when they fall into the large packaging bags, causing the large bags of materials to be in a mess, which to a certain extent reduces the packaging efficiency and the qualified rate of the materials. Utility Model Content

[0004] In order to solve the technical problem that secondary packaging is easily damaged, the utility model provides a secondary packaging material dropping and bag dragging mechanism.

[0005] The utility model is realized by adopting the following technical scheme: a secondary packaging blanking bag dragging mechanism.

[0006] It includes a bag dragging assembly and a board holding assembly, the bag dragging assembly includes a supporting rod and a bag dragging unit, the bag dragging unit is arranged in the board holding assembly, a base is arranged below the two board holding assemblies, a material receiving bin is arranged above the board holding assembly, and the material receiving bin is arranged at the output end of the blanking belt for receiving materials, a mechanical arm is also provided on the material receiving bin, and a woven bag can be sleeved on the mechanical arm.

[0007] Through the above technical solution, when the small bag material falls into the woven bag for collection under the action of the bag dragging mechanism, it is buffered by the bag dragging mechanism, so that the impact of the small bag material falling to the bottom of the woven bag is reduced, thereby reducing the possibility of the small bag material breaking and spilling.

[0008] As a further improvement of the above scheme, the bag dragging unit includes a supporting rod bracket, a connecting seat, a mounting base, a cylinder mounting plate, a cylinder ear seat, a cylinder, a joint bearing, a rotating connecting rod 1, a rotating connecting rod 2, a supporting rod, a fixing unit and a stabilizing unit;

[0009] A connecting rod is provided at one end of the multiple support rods away from each other, and one connecting rod and one end of three support rod brackets are fixed, wherein the other ends of the two support rod brackets are respectively hinged in the connecting seats, the other end of the other support rod bracket is hinged on the support rod, and the two sides of the support rod are hinged in the connecting seat, the side of the support rod away from the connecting seat is hinged to one end of the second rotating link, the other end of the second rotating link is respectively hinged to the joint bearing and one end of the first rotating link, the other end of the joint bearing is connected to one end of the cylinder, the other end of the cylinder is hinged to one end of the cylinder ear seat, the other end of the cylinder ear seat is hinged to one end of the cylinder mounting plate, the other end of the cylinder mounting plate is arranged on the mounting base plate, three connecting seats are fixed on the mounting base plate at equal distances, and both ends of the mounting base plate are arranged in the holding plate assembly.

[0010] Through the above technical solution, by connecting multiple supporting rods to a supporting rod bracket, when the supporting rod bracket moves, multiple supporting rods can be driven to rotate together. Therefore, the small bag material can be placed on the supporting rod more stably. And by pushing the joint bearings closer to each other, the rotating connecting rod 1 and the rotating connecting rod 2 are angled or aligned in the same straight line. The supporting rod is in a horizontal state or a vertical state, and the material receiving and discharging work is performed.

[0011] As a further improvement of the above scheme, the fixing unit includes a support rod rotating shaft and a support rod fixed support, both ends of the support rod rotating shaft are arranged in the holding plate assembly and are located on the mounting base, a fixing plate is provided in the holding plate assembly on one side of the support rod rotating shaft, one end of the two support rod fixed supports is fixed on the fixing plate, and the other end of the support rod fixed support is arranged on the support rod rotating shaft, and the other end of the rotating connecting rod is slidably arranged on the support rod rotating shaft.

[0012] Through the above technical solution, the support rod rotating shaft is used to fix one end of the rotating link rod 1, so that when the rotating link rod 1 is pushed closer to each other by the joint bearing, the position of the rotating link rod 1 can be more stable.

[0013] As a further improvement of the above scheme, the stabilization unit includes a material receiving plate, a side plate and an electric push rod, one end of the electric push rod is arranged in the base, and the output end of the electric push rod is connected to the material receiving plate, one end of the two side plates is connected to the material receiving plate, and the other ends of the two side plates are located in the holding plate assembly.

[0014] Through the above technical solution, the electric push rod drives a receiving plate and two side plates to move up and down, so that the distance between the support rod and the receiving plate can be changed from close to far. The small bag material on the support rod can fall on the receiving plate more stably, and is simply limited between the two side plates, which enhances the stability of the device and reduces the impact force generated when the small bag material falls.

[0015] As a further improvement of the above solution, a plurality of balls are rolled and embedded on the outside of the support rod.

[0016] Through the above technical solution, by providing multiple rollers on the outside of the support rod, the friction generated when the support rod and the small bag material come into contact can be reduced, so that the small bag material can be softened on the support rod. And the subsequent support rod is smoother when discharging the material.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. It has a cushioning effect on the falling process of small bag materials to avoid damage and spillage of small bag materials.

[0019] 2. It ensures the flatness of large bags of materials, reduces the probability of small bags slipping and causing chaos on site, and improves the packaging efficiency and qualified rate of materials to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Please combine Figure 1-5 , a secondary packaging blanking bag dragging mechanism of this embodiment includes a bag dragging assembly 1 and a holding board assembly 2, the bag dragging assembly 1 includes a supporting rod 1-1 and a bag dragging unit, the bag dragging unit is arranged in the holding board assembly 2, a base is arranged below the two holding board assemblies 2, a material receiving bin 4 is arranged above the holding board assembly 2, and the material receiving bin 4 is arranged at the output end of the blanking belt for receiving materials, and a mechanical arm is also arranged on the material receiving bin 4, and a woven bag 3 can be sleeved on the mechanical arm. The bag dragging unit includes a supporting rod bracket 1-2, a connecting seat 1-3, a mounting base plate 1-4, a cylinder mounting plate 1-5, a cylinder ear seat 1-6, a cylinder 1-7, a joint bearing 1-8, a rotating connecting rod 1-9, a rotating connecting rod 2 1-10, a supporting rod 1-13, a fixing unit and a stabilizing unit;

[0030] A connecting rod is provided at one end of the multiple supporting rods 1-1 away from each other, and one connecting rod is fixed to one end of three supporting rod brackets 1-2, wherein the other ends of two supporting rod brackets 1-2 are respectively hinged in the connecting seat 1-3, the other end of another supporting rod bracket 1-2 is hinged on the supporting rod 1-13, and both sides of the supporting rod 1-13 are hinged in the connecting seat 1-3, the side of the supporting rod 1-13 away from the connecting seat 1-3 is hinged to one end of the rotating connecting rod 2 1-10, and the other end of the rotating connecting rod 2 1-10 is hinged to the connecting seat 1-3. The other end of the joint bearing 1-8 is hinged to one end of the cylinder 1-7, the other end of the cylinder 1-7 is hinged to one end of the cylinder ear seat 1-6, the other end of the cylinder ear seat 1-6 is hinged to one end of the cylinder mounting plate 1-5, and the other end of the cylinder mounting plate 1-5 is arranged on the mounting base plate 1-4. Three connecting seats 1-3 are fixed on the mounting base plate 1-4 at equal distances, and both ends of the mounting base plate 1-4 are arranged in the holding plate assembly 2.

[0031] The implementation principle of a secondary packaging material dropping bag dragging mechanism in the embodiment of the present application is as follows: first, the mechanical arm arranged at the bottom of the receiving bin 4 is used to clamp one end of the opening of the woven bag 3, and the sealed end of the woven bag 3 is located between the two holding plate assemblies 2 and in contact with the receiving plate 5. The electric push rod 8 is started to drive the receiving plate 5 to approach the dragging bag assembly 1, and also drives the two side plates 7 to approach the dragging bag assembly 1 inside the holding plate assembly 2. When the electric push rod 8 reaches the bottom of the dragging bag assembly 1, before the small bag material 6 falls from the receiving bin 4, the cylinder 1-7 is retracted, and the rotating connecting rod 1-9 and the rotating connecting rod 2 1-10 rotate around the supporting rod rotating shaft 1-11 toward the cylinder ear seat 1-6. Because one end of the supporting rod fixed support 1-12 is fixed to the connecting seat 1-3, the supporting rod 1-1 and the supporting rod bracket 1-2 are rotated 90 degrees, so that the supporting rod 1-1 remains horizontal and is located above the receiving plate 5. At this time, the rotating connecting rod 1-9 and the rotating connecting rod 2-10 are in the same vertical direction, and the entire mechanism is at the connecting rod dead point position. The small bag material 6 falls onto the surface of the drag bag assembly 1 through the receiving bin 4, and the impact force of the fall is completely eliminated by the dead point effect of the connecting rod. Then the cylinder 1-7 quickly extends to push the rotating connecting rod 2-10 and the rotating connecting rod 1-9 to generate an angle, so that the supporting rod 1-1 changes from a horizontal state to a vertical state. The small bag material 6 on the supporting rod 1-1 falls on the receiving plate 5 under the action of gravity, and is located between the two side plates 7. At this time, the electric push rod 8 is started to drive the receiving plate 5 to move downward, driving the side plates 7 to move downward, and then the distance between the small bag material 6 above the receiving plate 5 and the supporting rod 1-1 can place another small bag material 6. This reciprocating operation ensures that multiple small bag materials 6 fall into the woven bag 3 as a whole and smoothly, greatly reducing the probability of bag flipping. Then the two cylinders 1-7 are controlled by the same solenoid valve to achieve synchronous operation.
