A mortar packaging bag conveying device

Abstract

This invention relates to the field of mortar packaging, specifically to a mortar packaging bag conveying device, including a bag feeding track, a pressing mechanism, and several bag opening mechanisms. This mortar packaging bag conveying device opens the bag openings of the mortar packaging bags through the bag opening mechanisms, and then conveys the bags by placing these mechanisms on the bag feeding track, allowing the mortar packaging bags to move to the bottom of the sand outlet of the packaging machine body. The pressing mechanisms then press the packaging bags tightly. This process only requires the worker to push the bag opening mechanisms; the worker does not need to touch the clamps or position the packaging bags at the time, thus speeding up the bag installation efficiency and preventing worker fingers from being pinched by the clamps. One worker can operate multiple production lines from the entrance of the bag feeding track. Furthermore, after filling is complete, the bag opening mechanisms automatically retract. The entire process requires no worker intervention, saving worker time.

Description

Technical Field

[0001] This invention relates to the field of mortar packaging, and more specifically to a mortar packaging bag conveying device. Background Technology

[0002] When packaging mortar, workers need to place the bag opening onto the clamp, and then the gate on the packaging machine opens to pour the mortar from the bag into the mortar packaging bag. When workers put on the packaging bag, the position of the packaging bag needs to be adjusted on the spot to avoid affecting the subsequent clamping and sewing. During the installation process, workers need to pay extra attention to avoid the clamps pinching their fingers. The installation method by workers is dangerous and slow. Summary of the Invention

[0003] The purpose of this invention is to provide a packaging bag conveying device for mortar packaging.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A mortar packaging bag conveying device is provided, including a bag feeding track, a pressing mechanism, and several bag opening mechanisms. The bag opening mechanisms are used to open the bag openings of the mortar packaging bags. The several bag opening mechanisms are horizontally slidably installed on the bag feeding track. When the bag opening mechanisms move to the end of the bag feeding track, they are located directly below the sand outlet of the packaging machine body. The pressing mechanism is used to press the bag opening mechanisms at the end of the bag feeding track.

[0006] The bag opening mechanism includes a support guide rail, a limiting and blocking mechanism, two opening mechanisms, and an elastic pull-back mechanism. The two opening mechanisms are located on both sides of the support guide rail and are slidably connected to it. The two elastic pull-back mechanisms are fixedly installed on both sides of the support guide rail and are used to apply an elastic force to the opening mechanisms to move towards the support guide rail. The limiting and blocking mechanism is fixedly installed on the support guide rail and is used to limit and resist the two opening mechanisms after they are opened. During the process of the pressing mechanism pressing the opening mechanisms downward, the pressing mechanism will push the limiting and blocking mechanism to open, so that the limiting and blocking mechanism no longer obstructs the opening mechanisms. The two opening mechanisms move a set distance towards the support guide rail. As the pressing mechanism continues to move, it will press the two opening mechanisms together.

[0007] Furthermore, the clamping mechanism includes two single-sided clamping mechanisms, which are located on opposite sides of the support guide rail. Each single-sided clamping mechanism can clamp the spreading mechanism. Each single-sided clamping mechanism is equipped with two limiting baffles, which are fixedly installed on the clamping plate of the clamping mechanism through an extension plate. The two limiting baffles are used to limit and block the two spreading mechanisms that move inward.

[0008] Furthermore, the spreading mechanism includes a bent support plate and a square guide post. The bent support plate is triangular, and a straight support plate is provided at the end of the bent support plate. The square guide post is fixedly installed at the end of the straight support plate and is slidably connected to the support rail.

[0009] Furthermore, the limiting and blocking mechanism includes a first connecting plate, two displacement plates, two baffles, two drive plates, two first guide posts, and two abutting springs. The two displacement plates are respectively fixedly installed on the linear support plates of the two spreading mechanisms. The two baffles are respectively used to block the inner sides of the two displacement plates. The two ends of the first connecting plate are fixedly connected to the two baffles. The two drive plates are respectively fixedly installed on the top of the two baffles for being pushed by the descending pressing plate. The first guide post is slidably connected to the first connecting plate and is fixedly installed on the support guide rail. The end of the first guide post is provided with a limiting circular plate. The abutting spring is used to apply an elastic force away from the limiting circular plate to the first connecting plate.

[0010] Furthermore, the support guide rail includes a second connecting plate and two conduits, which are respectively fixedly installed on both ends of the second connecting plate, and square guide posts are slidably inserted into the conduits.

[0011] Furthermore, the elastic pull-back mechanism is a tension spring, with one end of the tension spring fixedly connected to the bending support plate and the other end fixedly connected to the second connecting plate.

[0012] Furthermore, the single-sided pressing mechanism includes a lower push plate, a second guide post, a push cylinder, and a guide slide. The second guide post is slidably connected to the guide slide. The lower push plate is fixedly installed on the top of the second guide post. The push cylinder is fixedly installed on the guide slide. The output end of the push cylinder is fixedly connected to the lower push plate. The lower push plate is a pressing plate.

[0013] Furthermore, the bag feeding track includes a support frame and two L-shaped support plates, which are fixedly installed on the support frame, with the outer edge of the straight support plate fitting against the inner edge of the L-shaped support plate.

[0014] The beneficial effects of this invention are as follows: The mortar packaging bag conveying device opens the mouth of the mortar packaging bag through the bag opening opening mechanism, and conveys the mortar packaging bag by placing the bag opening opening mechanism on the bag feeding track, thereby moving the mortar packaging bag to the bottom of the sand outlet of the packaging machine body, and then pressing the packaging bag through the pressing mechanism. This process only requires the worker to push the bag opening opening mechanism, without the worker needing to touch the clamp, and also without the worker needing to position the packaging bag at the time, which speeds up the installation efficiency of the packaging bag, avoids the worker's fingers being pinched by the clamps, and allows one worker to operate multiple production lines while standing at the entrance of the bag feeding track;

[0015] Furthermore, once filling is complete, the bag opening mechanism automatically retracts, no longer tightening the bag opening, allowing the bag to proceed with subsequent processes. The entire process requires no worker intervention, saving workers' time. Attached Figure Description

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0027] Reference Figure 1 and Figure 2 The mortar packaging bag conveying device shown includes a bag feeding track 2, a pressing mechanism 4, a mortar packaging bag 5, and several bag opening mechanisms 3. The bag opening mechanisms 3 are used to open the bag opening of the mortar packaging bag 5. Several bag opening mechanisms 3 are horizontally slidably installed on the bag feeding track 2. When the bag opening mechanisms 3 move to the end of the bag feeding track 2, they are located directly below the sand outlet of the packaging machine body 1. The pressing mechanism 4 is used to press the bag opening mechanisms 3 at the end of the bag feeding track 2.

[0028] like Figure 3 As shown, the bag opening mechanism 3 includes a support rail 3b, a limiting blocking mechanism 3d, two opening mechanisms 3a, and an elastic pull-back mechanism 3c. The two opening mechanisms 3a are located on both sides of the support rail 3b, and both opening mechanisms 3a are slidably connected to the support rail 3b. The two elastic pull-back mechanisms 3c are fixedly installed on both sides of the support rail 3b and are used to apply an elastic force to the opening mechanisms 3a to move towards the support rail 3b. The limiting blocking mechanism 3d is fixedly installed on the support rail 3b and is used to limit and resist the two opening mechanisms 3a after they are opened. During the process of the pressing mechanism 4 pressing the opening mechanisms 3a downward, the pressing mechanism 4 will push the limiting blocking mechanism 3d to open, so that the limiting blocking mechanism 3d no longer blocks the opening mechanisms 3a. The two opening mechanisms 3a move a set distance towards the support rail 3b. As the pressing mechanism 4 continues to move, it will press the two opening mechanisms 3a tightly.

[0029] In this invention, such as Figure 3 As shown, the clamping mechanism 4 includes two single-sided clamping mechanisms, which are located symmetrically on both sides of the support guide rail 3b. Each single-sided clamping mechanism can clamp the opening mechanism 3a. Each single-sided clamping mechanism is equipped with two limiting baffles 4a, which are fixedly mounted on the clamping plate of the clamping mechanism 4 via extension plates. The two limiting baffles 4a are used to limit and block the inward movement of the two opening mechanisms 3a. When the clamping mechanism 4 moves downward, before the clamping mechanism 4 opens the limiting blocking mechanism 3d, the two limiting baffles 4a will insert between the opening mechanism 3a and the support guide rail 3b, thus preparing to block the subsequent movement of the opening mechanism 3a.

[0030] In this invention, such as Figure 3As shown, the opening mechanism 3a includes a bent support plate 3a1 and a square guide post 3a2. The bent support plate 3a1 is triangular, and a straight support plate 3a3 is also provided at the end of the bent support plate 3a1. The square guide post 3a2 is fixedly installed at the end of the straight support plate 3a3 and is slidably connected to the support guide rail 3b. Because the bent support plate 3a1 has a triangular structure, when the clamping device clamps the mortar packaging bag 5 filled with mortar, the bag opening will not be wrinkled, avoiding problems in subsequent sewing. In order to facilitate the separation of the bag opening of the mortar packaging bag 5 from the opening mechanism 3a, the triangular end of the opening mechanism 3a is rounded, and the connection between the opening mechanism 3a and the straight support plate 3a3 is also rounded.

[0031] In this invention, such as Figure 4 and Figure 5 As shown, the limiting and blocking mechanism 3d includes a first connecting plate 3d4, two displacement plates 3d1, two baffles 3d2, two drive plates 3d3, two first guide posts 3d5, and two abutting springs 3d6. The two displacement plates 3d1 are respectively fixedly installed on the linear support plates 3a3 of the two spreading mechanisms 3a. The two baffles 3d2 are respectively used to block the inner sides of the two displacement plates 3d1. The two ends of the first connecting plate 3d4 are fixedly connected to the two baffles 3d2. The two drive plates 3d3 are respectively fixedly installed on the top of the two baffles 3d2 for being pushed by the descending pressing plate. The first guide post 3d5 is slidably connected to the first connecting plate 3d4. The first guide post 3d5 is fixedly installed on the support guide rail 3b. The end of the first guide post 3d5 is provided with a limiting circular plate. The abutting springs 3d6 are used to apply an elastic force away from the limiting circular plate to the first connecting plate 3d4. When supporting the opening of the mortar packaging bag 5, the worker pushes the bending support plate 3a1 outward, so that the two bending support plates 3a1 open the opening of the mortar packaging bag 5, so that the inner edge of the mortar packaging bag 5 abuts against the outer edge of the opening mechanism 3a. During the process of the opening mechanism 3a being pulled outward, the opening mechanism 3a will also pull the displacement plate 3d1 to move. When the end of the displacement plate 3d1 is pulled out between the two baffles 3d2, the contact spring 3d6 will push the first connecting plate 3d4, so that the first connecting plate 3d4 drives the baffle 3d2 to abut against the support guide rail 3b, thereby blocking the displacement plate 3d1 and keeping the two opening mechanisms 3a in the open state.

[0032] During the downward movement of the clamping plate, the clamping plate will push the drive plate 3d3 to move, so that the drive plate 3d3 pushes the baffle 3d2 to move, so that the baffle 3d2 no longer blocks the displacement plate 3d1, and the two opening mechanisms 3a will be pulled back to their original positions by the elastic pull-back mechanism 3c, so that the opening mechanism 3a no longer fixes the opening of the mortar packaging bag 5.

[0033] In this invention, such as Figure 4As shown, the support rail 3b includes a second connecting plate 3b2 and two conduits 3b1. The two conduits 3b1 are fixedly installed on both ends of the second connecting plate 3b2, and the square guide post 3a2 is slidably inserted into the conduit 3b1. The conduits 3b1 guide the movement of the square guide post 3a2, and the two conduits 3b1 are connected by the second connecting plate 3b2.

[0034] In this invention, such as Figure 3 As shown, the elastic pull-back mechanism 3c is a tension spring, with one end fixedly connected to the bending support plate 3a1 and the other end fixedly connected to the second connecting plate 3b2. The tension applied by the elastic pull-back mechanism 3c causes the bending support plate 3a1 to move towards the support guide rail 3b.

[0035] In this invention, such as Figure 6 As shown, the single-sided pressing mechanism includes a lower push plate 4b, a second guide post 4c, a push cylinder 4d, and a guide slide 4e. The second guide post 4c is slidably connected to the guide slide 4e. The lower push plate 4b is fixedly installed on the top of the second guide post 4c. The push cylinder 4d is fixedly installed on the guide slide 4e, and the output end of the push cylinder 4d is fixedly connected to the lower push plate 4b. The lower push plate 4b is a pressing plate. The push cylinder 4d is controlled by the controller to push the lower push plate 4b downward. The lower push plate 4b will press against the two opening mechanisms 3a and fix the two opening mechanisms 3a. During the pressing process, the lower push plate 4b will push the drive plate 3d3, which will push the baffle 3d2 to move horizontally. During the movement of the lower push plate 4b, the lower push plate 4b will also drive the limit baffle 4a to move.

[0036] In this invention, such as Figure 7 As shown, the bag feeding track 2 includes a support frame 2b and two L-shaped support plates 2a. The two L-shaped support plates 2a are fixedly installed on the support frame 2b, and the outer edge of the straight support plate 3a3 is in contact with the inner edge of the L-shaped support plate 2a. The straight support plate 3a3 is supported by the L-shaped support plate 2a, so that the straight support plate 3a3 can slide along the L-shaped support plate 2a when pushed, ensuring that the bag opening mechanism 3 can be conveyed along the bag feeding track 2.

[0037] Working principle: The worker places the bag opening mechanism 3 and the mortar packaging bag 5 on the bag feeding track 2, so that the L-shaped support plate 2a supports the straight support plate 3a3. Then, the worker pushes the first bag opening mechanism 3, so that several bag opening mechanisms 3 placed on the bag feeding track 2 are pushed. Several bag opening mechanisms 3 will slide along the bag feeding track 2, so that the last bag opening mechanism 3 moves to below the discharge port of the packaging machine body 1.

[0038] Then, the controller controls the push cylinder 4d to work, so that the push cylinder 4d pushes the push plate 4b downward, and the push plate 4b presses against the two opening mechanisms 3a, thus fixing the two opening mechanisms 3a.

[0039] During the pressing process of the lower push plate 4b, the lower push plate 4b will push the drive plate 3d3 to move, so that the drive plate 3d3 pushes the baffle 3d2 to move, so that the baffle 3d2 no longer blocks the displacement plate 3d1. The two opening mechanisms 3a will be pulled back and reset by the elastic pull mechanism 3c. However, during the reset process of the opening mechanism 3a, since the pressing mechanism 4 has not yet opened the limit blocking mechanism 3d, the two limit baffles 4a will be inserted between the opening mechanism 3a and the support guide rail 3b to limit and block the opening mechanism 3a during the reset process, ensuring that the end of the displacement plate 3d1 can be inserted between the two baffles 3d2, so that when the pressing mechanism 4 is reset later, the baffle 3d2 will no longer block the displacement plate 3d1. Of course, it is also possible not to set the limit baffles 4a. As long as the speed of the pushing cylinder 4d is fast enough, it can press the opening mechanism 3a before the opening mechanism 3a moves out of the pressing range of the lower push plate 4b.

[0040] After the mortar packaging bag 5 is compressed, the packaging machine body 1 is controlled by the controller to work, so that the mortar packaging bag 5 is filled with mortar. Then, the push cylinder 4d is controlled by the controller to reset, so that the compression of the mortar packaging bag 5 is released. The elastic pull-back mechanism 3c will pull the two opening mechanisms 3a inward, so that the two opening mechanisms 3a will no longer tighten the bag opening of the mortar packaging bag 5. When the clamping device clamps the bag opening of the mortar packaging bag 5 and moves it downward, the bag opening of the mortar packaging bag 5 will be pulled downward along the edge of the opening mechanism 3a. The mortar packaging bag 5 is then conveyed to the sewing mechanism for sewing.

[0041] The bag opening mechanism 3 remaining on the bag feeding track 2 will cause the end bag opening mechanism 3 to be dislodged from the bag feeding track 2 when the worker pushes the first bag opening mechanism 3, so that the bag feeding track 2 can slide into the collection device for collection, and prepare for the subsequent opening of the mortar packaging bag 5.
