Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a material bag production line. Background Art

[0002] In the traditional bag production process, materials undergo a complete flow from initial processing to final packaging. This process typically begins with the material being formed and sealed in a packaging machine, forming a continuous bag belt. The belt is then conveyed to a bag dispenser, where it is precisely cut and divided into individual bags. From there, the bags are transported to a designated collection area for packaging and shipping. However, this seemingly straightforward and continuous production process presents significant efficiency and production control challenges in practice.

[0003] Specifically, since the number and speed of material bags cut out by the bag-feeding machine are directly subject to the working efficiency of the upstream packaging machine, when the material bag generation speed is too fast, the material bags are likely to accumulate in the collection area. At this time, the machine needs to be stopped and the material bags need to be cleared or collected, thereby interrupting the continuous processing of the production line and reducing production efficiency; on the contrary, if the material bag supply is insufficient, it will not only reduce the efficiency of the staff in collecting the material bags, but also affect the subsequent production process, thereby extending the production cycle of the entire production line. Based on this, the present application proposes a production line that can quantitatively deliver material bags to avoid the situation where the production efficiency is reduced and the production cycle is extended due to the mismatch between the material bag generation speed and the collection speed. Utility Model Content

[0004] The main purpose of the utility model is to provide a material bag production line, aiming to solve the problem that the existing material bag production line is prone to reduce production efficiency and extend production cycle due to the mismatch between the material bag generation speed and the collection speed.

[0005] To achieve the above-mentioned purpose, the utility model provides a material bag production line, including a conveying device, a loading device and several buffer devices, a packaging machine and a bag throwing machine. The several buffer devices, packaging machines and bag throwing machines are respectively arranged at intervals along the extension direction of the conveying device. A conveying frame for conveying the material bag belt is provided between the packaging machine and the bag throwing machine. The buffer device is used to receive and deliver the material bags cut by the bag throwing machine to the conveying device. The loading device is provided at the discharge end of the conveying device, and the loading device is used to place the collection bag.

[0006] Preferably, the cache device includes a support frame and a detection unit, a driving member and a hopper arranged on the support frame. The support frame is detachably connected to the conveying device. A feed port is provided on the hopper at a position corresponding to the conveyor belt of the bag-dropping machine. A discharge port is formed at the bottom of the hopper and a gate is movably provided. The driving member is communicatively connected to the detection unit, and the power output end of the driving member is transmission-connected to the gate so as to drive the gate to move and open or close the discharge port through the driving member.

[0007] Preferably, a plurality of the hoppers, detection units and driving members are arranged at intervals on the support frame along its height direction, the plurality of the hoppers, detection units and driving members are arranged in one-to-one correspondence, and the tops of the plurality of the hoppers are all opened.

[0008] Preferably, the gate includes two inclined plates, which are symmetrically arranged relative to the hopper, and one end of the two inclined plates is hinged to the hopper respectively. A connecting seat is detachably installed on the power output end of the driving member, and two connecting rods are hinged on the connecting seat, and the two connecting rods are rotatably connected to the two inclined plates respectively.

[0009] Preferably, baffles are formed on opposite side edges of the two inclined plates.

[0010] Preferably, the loading device comprises a turntable, on which a plurality of mounting seats are detachably mounted along its circumference, and the plurality of mounting seats are all hollow and used for mounting the collecting bags.

[0011] Preferably, a conveying device is further included, which is arranged close to the turntable and is used to transport the collection bag filled with material bags.

[0012] Preferably, both ends of the conveying frame are detachably connected to the packaging machine and the bag-dropping machine, respectively, and the conveying frame is provided with a plurality of traction wheels at intervals along its extending direction.

[0013] Beneficial effects:

[0014] 1. In a material bag production line of the present invention, the caching effect of several buffer devices on the material bags can coordinate the material bag generation speed and collection speed, so that the material bags can be piled and distributed at intervals on the conveying device and conveyed to the loading device at a preset speed, thereby facilitating the collection and sub-packaging of the material bags by the staff. This not only effectively avoids the accumulation of material bags and improves production efficiency, but also ensures the processing continuity of the entire production line.

[0015] 2. In a material bag production line of the utility model, the capacity of the buffer device can be matched with the capacity of the collection bag during the actual production and manufacturing process, that is, the amount of material bags discharged by the buffer device during a single discharge process is just enough to fill a single collection bag, thereby ensuring an adequate supply of material bags. There is no need for staff to wait for multiple supplies of material bags to fill the collection bag, which improves the efficiency of collecting material bags and ensures the orderly progress of subsequent production processes, thereby ensuring the production rhythm and cycle of the entire production line.

[0016] 3. During the actual operation of a material bag production line of the utility model, since the conveying device continuously conveys material bags to the loading device, the staff can place several collection bags on the loading device at the same time. When a single collection bag is full, the staff can remove it and move the next empty collection bag to the discharge end of the conveying device, thereby sustainably receiving material bags, effectively ensuring the continuity of receiving and packaging material bags, and further improving the collection efficiency.

[0029] Example 1:

[0030] The utility model provides a material bag production line.

[0031] In one embodiment of the present invention, a material bag production line includes a conveying device 1, a loading device 2 and several buffer devices 3, a packaging machine 4 and a bag throwing machine 5. The several buffer devices 3, the packaging machine 4 and the bag throwing machine 5 are respectively arranged at intervals along the extension direction of the conveying device 1. A conveying rack 6 for conveying the material bag belt is provided between the packaging machine 4 and the bag throwing machine 5. The buffer device 3 is used to receive and deliver the material bags cut by the bag throwing machine 5 to the conveying device 1. The discharging end of the conveying device 1 is provided with a loading device 2, and the loading device 2 is used to place the collection bag.

[0032] Specifically, if Figures 1 to 4 As shown, in a material bag production line of the present invention, a packaging machine 4 can package the material and make a continuous material bag belt. At the same time, a conveyor frame 6 can convey the material bag belt to a bag dispenser 5, and the bag dispenser 5 cuts the material bag belt to divide the material bag belt into several independent material bags. When the material bag is discharged from the bag dispenser 5, it falls into the buffer device 3 for buffering. After the buffer device 3 reaches the preset delivery condition, the material bag can be delivered to the conveyor device 1. The conveyor device 1 can be a chain conveyor in the prior art, and two guardrails are provided on the conveyor belt of the conveyor device 1 at intervals. This can stably convey the material bag to the loading device 2, thereby facilitating the staff to package and transport the material bag through the collection bag.

[0033] Furthermore, since several cache devices 3, packaging machines 4 and bag-dropping machines 5 are respectively arranged at intervals along the extension direction of the conveying device 1, the speed of generating material bags can be accelerated by several packaging machines 4 and bag-dropping machines 5, thereby improving the production efficiency of the entire production line; at the same time, since each bag-dropping machine 5 is correspondingly provided with a cache device 3, the cache device 3 can be specifically a tray or a tank body whose discharge port can be opened and closed, that is, a corresponding timer is provided in the cache device 3. When the timer reaches the set time, it means that the cache device 3 is full of material bags. At this time, the discharge port of the cache device 3 automatically opens and drops all the stored material bags onto the conveying device 1. After the dropping is completed, the discharge port automatically closes to allow the cache device 3 to continue to receive and store the material bags. The structural design is simple and reasonable. It is worth noting that, since the packaging machine 4 and the bag-feeding machine 5 continuously deliver material bags to the buffer device 3 during operation, in order to prevent excess material bags from falling out through the buffer device 3 when the buffer device 3 delivers material bags to the conveying device 1, the buffer device 3 can be made into a multi-layer structure (such as two trays stacked on top of each other, and the discharge ports at the bottom of the two trays can be switched on and off), so as to achieve synchronous operation of the buffer device 3 receiving and delivering material bags. In addition, it is obvious that the caching effect of several buffer devices 3 on material bags can coordinate the generation speed and collection speed of material bags, so that the material bags can be piled and distributed at intervals on the conveying device 1 and delivered to the loading device 2 at a preset speed, thereby facilitating the collection and sub-packaging of material bags by the staff, which not only effectively avoids the accumulation of material bags and improves production efficiency, but also ensures the processing continuity of the entire production line.

[0034] It is understandable that the capacity of the buffer device 3 can be matched with the capacity of the collection bag during the actual production and manufacturing process, that is, the amount of material bags discharged by the buffer device 3 during a single discharge process is just enough to fill a single collection bag, thereby ensuring an adequate supply of material bags, eliminating the need for staff to wait for multiple supplies of material bags to fill the collection bag, improving the efficiency of collecting material bags, and ensuring the orderly progress of subsequent production processes, ensuring the production rhythm and cycle of the entire production line. In addition, since the conveying device 1 continuously conveys material bags to the loading device 2, during the actual operation of the present invention, the staff can place several collection bags on the loading device 2 at the same time. When a single collection bag is full, the staff can remove it and move the next empty collection bag to the discharge end of the conveying device 1, thereby continuously receiving material bags, effectively ensuring the continuity of receiving and packaging material bags, and further improving the collection efficiency.

[0035] It should be noted that in the material bag production line of the present invention, the packaging machine 4 and the bag-dropping machine 5 are both mature existing technologies. The packaging machine 4 can be an intelligent V-servo packaging machine 4 proposed by the applicant in the patent publication number CN212333044U. This intelligent V-servo packaging machine 4 can realize automatic packaging of materials and produce a continuous material bag belt. The bag-dropping machine 5 can be a high-speed bag-dropping machine 5 proposed by the applicant in the patent publication number CN109733697A. This high-speed bag-dropping machine 5 can realize automatic rolling and cutting of the material bag belt and divide it into several material bags. The specific structural composition and working principle of the packaging machine 4 and the bag-dropping machine 5 are not described in detail here. The present invention is only aimed at solving the problem that the existing material bag production line is prone to reducing production efficiency and extending the production cycle due to the mismatch between the material bag generation speed and the collection speed.

[0036] It's worth noting that a weighing scale is installed between the bag dispenser 5 and the buffer 3. This scale is typically used in conjunction with the bag dispenser 5 in existing bag production lines and is a mature, prior art technology. Specifically, after the bag dispenser 5 cuts the bag strip into individual bags, the bags fall onto the weighing scale, where they are weighed and judged for quality. This facilitates bag sorting and eliminates the need for manual bag testing, reducing labor and ensuring continuous production line operation. Because the weighing scale is prior art, its specific operating principles and structural components are not detailed here.

[0037] In one embodiment, the cache device 3 includes a support frame 7 and a detection unit, a driving member 8 and a hopper 9 arranged on the support frame 7. The support frame 7 is detachably connected to the conveying device 1. A feed port is provided on the hopper 9 at a position corresponding to the conveyor belt of the bag-dropping machine 5. A discharge port is formed at the bottom of the hopper 9 and a gate 10 is movably provided. The driving member 8 is communicatively connected with the detection unit, and the power output end of the driving member 8 is transmission-connected with the gate 10 so as to drive the gate 10 to move and open or close the discharge port through the driving member 8.

[0038] Specifically, if Figure 2 and Figure 3As shown, the support frame 7 can provide a stable support structure for the detection unit, the driving member 8 and the hopper 9, ensuring that the hopper 9 can stably receive the material bags delivered from the bag delivery machine 5, and the support frame 7 and the conveying device 1 can be detachably connected by a threaded connection, thereby facilitating the disassembly, assembly and replacement of the entire cache device 3. Furthermore, since a feed port is provided at the top of the hopper 9 corresponding to the position of the conveyor belt of the bag-dropping machine 5, the bag can be automatically conveyed into the hopper 9 via the conveyor belt of the bag-dropping machine 5; at the same time, since a detection unit is provided on the support frame 7, the detection unit can be an infrared probe, a weight sensor or a camera, etc., and the driving member 8 can be any one of an electric push rod, a cylinder, a hydraulic cylinder or a screw transmission, and the driving member 8 is communicatively connected with the detection unit. When the hopper 9 is full of bag, the detection unit detects that the hopper 9 is full. At this time, the driving member 8 runs and opens the gate 10, so that the bag in the hopper 9 can fall into the conveying device 1 through the discharge port, thereby completing the automatic delivery of the bag; similarly, when the bag is delivered, the driving member 8 closes the gate 10, so that the hopper 9 can receive and store the bag for the second time. The structural design is simple and reasonable.

[0039] In one embodiment, if Figure 2 and Figure 3 As shown, the support frame 7 is provided with a plurality of hoppers 9, detection units, and drive members 8 at intervals along its height. Each of these hoppers 9, detection units, and drive members 8 corresponds to each other, and the tops of each of the hoppers 9 are open. As can be understood, since the bag-dropping machine 5 continuously delivers bags to the hopper 9, when the hopper 9 is full, the drive member 8 opens the gate 10, allowing the bags to fall onto the conveyor device 1. During this process, to prevent excess bags from falling out of the discharge port when the hopper 9 opens its gate 10, the support frame 7 is provided with a plurality of hoppers 9, detection units, and drive members 8 at intervals along its height. Each of these hoppers 9, detection units, and drive members 8 corresponds to each other, allowing the gates 10 of each hopper 9 to be opened or closed independently, and the gates 10 of each hopper 9 to open and close alternately, thereby achieving batch storage of bags, effectively ensuring the delivery quantity and reliable use.

[0040] In one embodiment, the gate 10 includes two inclined plates 11, which are symmetrically arranged relative to the hopper 9. One end of the two inclined plates 11 is hinged to the hopper 9. A connecting seat 12 is detachably mounted on the power output end of the driving member 8. Two connecting rods 13 are hinged to the connecting seat 12. The two connecting rods 13 are rotatably connected to the two inclined plates 11. Specifically, Figure 3As shown, the power output end of the driving member 8 and the connecting base 12 can be detachably connected by a threaded connection, thereby facilitating the disassembly, assembly, and replacement of the driving member 8, the connecting base 12, and other components. Furthermore, because the two inclined plates 11 are symmetrically arranged relative to the hopper 9 and are rotatably connected to the connecting base 12 via two connecting rods 13, the two inclined plates 11 can rotate toward or away from each other under the action of the driving member 8 and the two connecting rods 13, thereby opening and closing the discharge port of the hopper 9. The structural design is ingenious and reasonable. At the same time, when the discharge port of the hopper 9 is opened, the two inclined plates 11 can block and guide the material bags, preventing them from falling and escaping into the other hopper 9 or outside the conveying device 1.

[0041] In one embodiment, specifically, Figure 3 As shown, baffles 14 are formed on the opposite side edges of the two inclined plates 11. When the discharge port of the hopper 9 is opened, the baffles 14 on the side edges of the two inclined plates 11 can limit the position of the material bag, so that the material bag can accurately fall into the preset position, thereby achieving efficient, stable and quantitative transportation of the material bag, and reliable use.

[0042] In one embodiment, if Figure 2 and Figure 4 As shown, the loading device 2 includes a turntable 15 with several mounting blocks 16 detachably mounted along its circumference. Each of these mounting blocks 16 is hollow and designed to hold collection bags. Specifically, each of the mounting blocks 16 and the turntable 15 is detachably connected via a threaded connection, making them easily removable, easy to install, and replace, and facilitating maintenance. Furthermore, since the mounting blocks 16 are hollow and arranged along the circumference of the turntable 15, workers can easily attach collection bags to the mounting blocks 16. When it is time to access material bags from the conveyor 1, simply aligning the collection bag with the discharge end of the conveyor 1 automatically causes the bag to fall into the collection bag, completing the automatic loading process. This is simple and convenient. As can be appreciated, when a collection bag is full, workers simply rotate the turntable 15 to align another empty collection bag with the discharge end of the conveyor 1 to access the next batch of bags from the conveyor 1. Obviously, during the entire process of collecting material bags, the staff only needs to put on and take out the collection bags, which not only greatly simplifies the staff's operation steps of collecting material bags, reduces labor intensity, but also improves work efficiency.

[0043] In one embodiment, a conveying device 17 is further included, which is arranged near the turntable 15 and is used to convey the collection bag filled with the material bag. Figures 1 to 4 As shown, the collection bag filled with material bags can be automatically transferred and transported to the next process through the conveying device 17, thereby eliminating the need for workers to repeatedly transport them back and forth, effectively ensuring the production efficiency of the entire production line.

[0044] In one embodiment, specifically, Figure 1 and Figure 2 As shown, the conveyor frame 6 is detachably connected to the packaging machine 4 and the bag dispenser 5 at both ends. A plurality of traction wheels 18 are provided at intervals along the conveyor frame 6. These traction wheels 18 form a relatively fixed conveying path, stably guiding the bag belt to the bag dispenser 5. This ensures continuous material supply to the bag dispenser 5 and efficient and continuous operation of the entire production line.

[0045] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
