Abstract

This utility model relates to the field of secondary bagging technology for powder materials, specifically a single-pack PE single-film soft bag vertical secondary bagging packaging machine. It includes a packaging machine body, with a double-sided clamping conveyor mechanism connected to the feeding end of the machine body. The double-sided clamping conveyor mechanism includes an upper conveyor belt unit and a lower conveyor belt unit. In this utility model, the operator pushes the soft bag towards the conveyor belts, and the two conveyor belts move the soft bag upwards. The ball bearings reduce the friction between the soft bag and the material preparation plate. Combined with the operator's pushing and clamping force, the initial resistance to be overcome during the upward movement of the soft bag by the upper and lower conveyor belt units is reduced, meaning the friction on the outer side of the soft bag is reduced, lowering the possibility of damage.

Moreover, the force applied to both sides increases the force-bearing area, further reducing the probability of the soft bag breaking.

Description

Technical Field

[0001] This utility model relates to the field of secondary bagging technology for powder materials, specifically a single-pack PE single-film soft bag vertical secondary bagging packaging machine. Background Technology

[0002] The secondary bagging packaging machine is a highly automated packaging equipment designed specifically for processes requiring secondary bagging or repackaging of powdered, granular, and lumpy materials that have already undergone initial packaging. It typically consists of a bag-picking, pre-opening, and bag-preparing robotic arm, a bag-clamping mechanism, a bag-holding mechanism, a shaping bin, a lower main frame, a bag-feeding lifting mechanism, a bag-mouth guiding mechanism, a straight-edge mechanism, a lifting and sewing conveyor, a material unloading bin, and a pressing and shaping conveyor. This equipment is widely used in the food, chemical, pharmaceutical, and feed industries. It significantly improves packaging efficiency and consistency, reduces labor costs and material waste, and greatly enhances product shelf life and transportation safety by providing secondary protection through sealing, moisture prevention, and light protection. Simultaneously, the neat and attractive outer bags effectively improve the overall market image and brand value of the product.

[0003] Some secondary packaging uses PE single-layer soft bags for the inner packaging, which have low wear resistance. In the current packaging technology, some packaging machines use inclined conveyor belts for feeding, relying on the friction between the conveyor belt and the soft film to move the inner packaging upward. When the material inside the inner packaging is heavy, the inner packaging is already damaged. Especially in the initial stage when the horizontal conveyor belt or manual feeding comes into contact with the inclined conveyor belt, the contact area between the inner packaging and the inclined conveyor belt is small. At this time, the stress on the inner packaging is concentrated, making it more prone to damage. Utility Model Content

[0004] To address the aforementioned issues, this application provides a single-pack PE single-film soft bag vertical secondary bagging packaging machine, which solves the problem of small contact area and easy damage when a single conveyor belt conveys inner packaging upwards.

[0005] A single-pack PE single-film soft bag vertical secondary bagging packaging machine includes a packaging machine body. The feeding end of the packaging machine body is connected to a double-sided clamping conveyor mechanism. The double-sided clamping conveyor mechanism includes an upper conveyor belt unit and a lower conveyor belt unit. The conveyor belts of the two conveyor units move at the same speed and in the same direction on one side of the soft bag, and apply force to both sides of the soft bag at the same time.

[0006] The bottom of the lower conveyor belt unit is equipped with a material preparation plate for placing soft packages. Multiple ball bearings are movably embedded above the material preparation plate to facilitate the workers to push the soft packages forward into the lower conveyor belt unit.

[0007] Preferably, the double-sided clamping conveyor mechanism further includes a support frame, which is fixed to the ground, and the upper conveyor belt unit and the lower conveyor belt unit are installed inside the support frame.

[0008] Preferably, a multi-functional box is fixedly installed on the outside of the support frame, and a material preparation plate is fixedly installed on the inside of the multi-functional box.

[0009] Preferably, the material preparation plate has multiple collection holes extending through its center.

[0010] Preferably, a collection drawer is slidably installed on the inner side of the multi-functional box, and a handle is provided at the end of the collection drawer.

[0011] Preferably, the multi-functional box has mating notches at both ends, with the bottom of the mating notches flush with the top of the ball bearings.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model describes a single-pack PE single-film soft bag vertical secondary bagging packaging machine. The operator pushes the soft bag towards the conveyor belt, and the two conveyor belts move the soft bag upwards. Ball bearings reduce the friction between the soft bag and the material preparation plate. Combined with the operator's pushing force, the initial resistance to be overcome during the upward movement of the soft bag by the upper and lower conveyor belt units is reduced. This means the friction on the outside of the soft bag is reduced, lowering the possibility of damage. Furthermore, the upper and lower sides of the soft bag are in contact with the conveyor belts of the upper and lower conveyor belt units respectively, which can smooth the soft bag. Moreover, the force applied to both sides increases the force-bearing area, further reducing the probability of the soft bag breaking.

[0014] If the soft packaging is damaged, the scattered materials slide down and enter the collection drawer through the collection hole, effectively preventing large-scale material spillage. Workers only need to take out the collected materials from the collection drawer, reducing the workload of workers and shortening downtime. Moreover, materials that have not fallen to the ground and have not been contaminated can be repackaged, reducing losses. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0025] First embodiment:

[0026] like Figure 1 , Figure 2 As shown, this utility model embodiment provides a single-pack PE single-film soft bag vertical secondary bagging packaging machine, including a packaging machine body 1. The feeding end of the packaging machine body 1 is connected to a double-sided clamping conveyor mechanism 2. The double-sided clamping conveyor mechanism 2 includes an upper conveyor belt unit 22 and a lower conveyor belt unit 23. The conveyor belts of the two conveyor units move at the same speed and in the same direction on the side that is in contact with the soft bag, applying force to both sides of the soft bag at the same time, increasing the force-bearing area, and making the soft bag less prone to damage. In the prior art, there are many ways to achieve synchronous rotation of the upper conveyor belt unit 22 and the lower conveyor belt unit 23. For example, using the same frequency converter or servo driver to drive the drive motors of the upper conveyor belt unit 22 and the lower conveyor belt unit 23 at the same time is a relatively mature technology, which will not be listed in this article.

[0027] In this embodiment, the upper conveyor belt unit 22 and the lower conveyor belt unit 23 are started. The staff pushes the soft bag to move towards the conveyor belt. The two conveyor belts drive the soft bag to move upward. The upper and lower sides of the soft bag are respectively in contact with the conveyor belts of the upper conveyor belt unit 22 and the lower conveyor belt unit 23, which can smooth the soft bag. Moreover, the force is applied on both sides, increasing the force-bearing area and reducing the probability of the soft bag breaking.

[0028] Specifically, such as Figure 2As shown, the double-sided clamping conveyor mechanism 2 also includes a support frame 21, which is fixed to the ground, and the upper conveyor belt unit 22 and the lower conveyor belt unit 23 are installed inside the support frame 21.

[0029] Second embodiment:

[0030] The difference from the above embodiments is that, as Figure 2 , Figure 3 , Figure 5 As shown, a material preparation plate 25 for placing soft packages is installed at the bottom of the lower conveyor belt unit 23. Multiple ball bearings 26 are movably embedded above the material preparation plate 25 to facilitate the workers to push the soft packages forward into the lower conveyor belt unit 23.

[0031] In this embodiment, the worker places multiple soft bags sequentially on top of the preparation plate 25 and the ball bearings 26, and smooths them initially with his palm. The worker then pushes the soft bags toward the conveyor belt, and the two conveyor belts move the soft bags upward. The ball bearings 26 reduce the friction between the soft bags and the preparation plate 25, and with the worker's pushing force, the resistance that needs to be overcome in the initial stage of the upper conveyor belt unit 22 and the lower conveyor belt unit 23 moving the soft bags upward is reduced. That is, the friction on the outside of the soft bags is reduced, and the possibility of damage is reduced.

[0032] Specifically, such as Figure 2 As shown, a multi-functional box 24 is fixedly installed on the outside of the support frame 21, and a material preparation plate 25 is fixedly installed on the inside of the multi-functional box 24.

[0033] Specifically, such as Figure 5 As shown, the material preparation plate 25 has multiple collection holes 27 through the middle, from which scattered materials fall.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, a collection drawer 28 is slidably installed inside the multi-functional box 24 for collecting scattered materials. A handle is provided at the end of the collection drawer 28 to facilitate the movement of the collection drawer 28 by the staff.

[0035] In this embodiment, if the soft packaging is damaged, the scattered material slides down and enters the collection drawer 28 through the collection hole 27, effectively preventing the material from scattering over a large area. The staff only needs to take out the material collected in the collection drawer 28, which reduces the workload of the staff and shortens the downtime. Moreover, the material that has not fallen to the ground and has not been contaminated can be repackaged, reducing losses.

[0036] Specifically, such as Figure 3 As shown, the multi-functional box 24 has mating notches 29 at both ends. The bottom of the mating notch 29 is flush with the top of the ball bearing 26, which makes it convenient for workers to put the soft package into the preparation plate 25 and push the soft package down the conveyor belt unit 23.

[0037] Specific working methods:

[0038] Workers arrange multiple soft bags sequentially on top of the preparation plate 25 and the ball bearings 26, and initially smooth them with their palms. The upper conveyor belt unit 22 and the lower conveyor belt unit 23 are started, and workers push the soft bags towards the conveyor belts. The two conveyor belts move the soft bags upwards. The ball bearings 26 reduce the friction between the soft bags and the preparation plate 25, and with the push and clamping force of the workers, the resistance that needs to be overcome in the initial stage of the upper conveyor belt unit 22 and the lower conveyor belt unit 23 moving the soft bags upwards is reduced. That is, the friction on the outside of the soft bags is reduced, and the possibility of damage is reduced. Furthermore, the upper and lower sides of the soft bags are in contact with the conveyor belts of the upper conveyor belt unit 22 and the lower conveyor belt unit 23, which can smooth the soft bags. Moreover, the force is applied on both sides, increasing the force-bearing area, and the probability of the soft bags breaking is further reduced.

[0039] If the soft packaging is damaged, the scattered materials slide down and enter the collection drawer 28 through the collection hole 27, effectively preventing the materials from scattering over a large area. The staff only needs to take out the materials collected in the collection drawer 28, which reduces the workload of the staff and shortens the downtime. Moreover, the materials that have not fallen to the ground and have not been contaminated can be repackaged, reducing losses.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
