Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a side-opening bag-feeding type packaging machine. Background Art

[0002] Bag-feeding packaging machines are used for packaging granules, various foods, seasonings, sauces, and liquids, and are widely used in the market.

[0003] In the prior art bag-feeding packaging machine, the clamping parts clamp the left and right sides of the packaging bag, and then the bag mouth of the packaging bag is opened or closed by the opening and closing action of the left and right clamping bodies of the clamping parts. The disadvantage is that the bag mouth of the packaging bag is opened passively. If the bag mouth of the packaging bag is to be opened larger and more regularly, a special bag-supporting part needs to be set at the feeding station, and the structure is complicated. Of course, for some bags with special structures, the clamping parts of the prior art are not applicable. For example, the side-opening bag feeding type packaging machine with patent authorization announcement number CN209870909U includes a dividing turntable, and the outer circumference of the dividing turntable is provided with a bag-loading station, a feeding station, a heat sealing station and a bag-loading station. Each station is provided with a set of machine clamp components, characterized in that: the machine clamp components adopt a side suction structure, the machine clamp components include a left machine clamp body and a right machine clamp body, and the opposite sides of the left and right machine clamp bodies are respectively arranged with a row of suction nozzles, and the left and right machine clamp bodies move toward or away from each other; a bag-loading conveying device for conveying the packaging bag is provided corresponding to the bag-loading station, and a clamp is provided at the outlet of the bag-loading conveying device, and the clamp moves between the outlet of the bag-loading conveying device and the machine clamp component of the bag-loading station, and the direction in which the packaging bag is fed into the machine clamp component is that the front and rear sides of the packaging bag face the suction nozzles on the left and right machine clamp bodies respectively. The utility model uses a suction nozzle bag-opening method to open the packaging bag, has a simple structure, a large bag opening, and is more convenient for loading materials.

[0004] The packaging bag is opened by sucking the packaging bag with a nozzle on the side of the packaging bag, but there are still defects: the above-mentioned device uses a nozzle to suck the packaging bag and then moves the nozzle to open the bag. However, due to different types of packaging bags, the plastic seal on the side of some packaging bags is relatively hard, which makes it difficult to open the opening when the packaging bag is sucked with the nozzle. At this time, if the negative pressure effect of the nozzle is increased, the front and rear side walls of the packaging bag will be sucked together, which will also make the opening of the packaging bag difficult to open. Therefore, the negative pressure effect generated at the nozzle cannot be too strong or too weak. However, when the plastic seal on the side of the packaging bag is relatively hard, the nozzle with medium suction strength will make the opening unable to open completely, thus affecting the subsequent packaging effect. Utility Model Content

[0005] The purpose of the utility model is to provide a side-opening bag-feeding type packaging machine to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above utility model purpose, the utility model adopts the following technical solutions:

[0008] A turntable is arranged on the top of the device box, and a first driving assembly for driving the turntable to rotate along its own central axis is arranged inside the device box;

[0009] A side-opening bag assembly is arranged on the top of the turntable, and includes a plurality of clamping assemblies arranged at equal intervals along the circumference of the turntable, wherein the clamping assembly includes two clamping blocks;

[0010] and a second driving assembly, which is arranged on the top of the device box and corresponds to the clamping assembly one by one; the second driving assembly is used to drive the two clamping blocks in the clamping assembly to move relative to each other or move away from each other;

[0011] A guide assembly corresponding to the clamping assembly is also provided on the top of the device box, and the guide assembly includes two first fixed boxes and two second fixed boxes, and each of the first fixed boxes and the second fixed boxes are connected by a connecting pipe; a first piston is provided inside the first fixed box, and the end of the first piston is connected to a first connecting rod that penetrates the outside of the first fixed box and is fixedly connected to the clamping block; a second piston is provided inside the second fixed box, and the end of the second piston is connected to a second connecting rod that penetrates the outside of the second fixed box, and the end of the second connecting rod is connected to an arc plate.

[0012] Preferably, a top plate is provided on the top of the device box through a bracket, and a feed opening corresponding to one of the clamping components is provided on the top plate.

[0013] Preferably, the first drive component includes a first motor installed inside the device box, and the output end of the first motor is connected to a first rotating shaft, and the outer part of the first rotating shaft is sleeved with a first gear; the first drive component also includes a second rotating shaft rotatably connected to the inside of the device box, and the top end of the second rotating shaft is connected to the bottom center of the turntable, and the second rotating shaft is sleeved with a second gear meshing with the first gear.

[0014] Preferably, the side-opening bag assembly also includes an annular block fixed at the center of the top of the turntable and an installation box located at the center of the annular block, and also includes a negative pressure pump fixed at the top of the turntable, the input end of the negative pressure pump is connected to an air inlet pipe, and the other end of the air inlet pipe is connected to the interior of the installation box; an arc-shaped cavity corresponding to the clamping assembly one by one is opened in the annular wall of the annular block, and the interior of the arc-shaped cavity is connected to the interior of the fixed box through a branch pipe, and an electromagnetic valve is installed on the branch pipe.

[0015] Preferably, an opening is provided at one end of the clamping block, and a branch hole communicating with the opening is provided inside the clamping block, and an air intake pipe for communicating the inside of the branch hole with the inside of the arc-shaped cavity is connected to the clamping block.

[0016] Preferably, the second driving assembly includes a second motor installed on the top of the device box, and the output end of the second motor is connected to the second motor, the output end of the second motor is connected to a bidirectional threaded rod, and two threaded blocks are symmetrically arranged on the bidirectional threaded rod, the two threaded blocks are rotationally connected to the bidirectional threaded rod through threads, and the tops of the two threaded blocks are fixedly connected to the bottoms of the two clamping blocks one by one.

[0017] Preferably, the driving assembly further comprises a guide rod fixed to the top of the turntable, and two guide blocks are sleeved on the guide rod, and the tops of the two guide blocks are respectively fixedly connected to the bottoms of the two clamping blocks one by one.

[0018] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0019] When the second driving assembly is used to open the packaging bag at the side, the two clamping blocks move away from each other to drive the first connecting rod to move toward the inside of the first fixing box, thereby causing the first piston inside the first fixing box to move. The first fixing box and the second fixing box are connected by the connecting pipe. Therefore, the movement of the first piston at this time can cause the second piston inside the second fixing box to drive the second connecting rod and the arc plate to move toward the clamping block, thereby squeezing the plastic seal on the side edge of the packaging bag between the clamping blocks. Therefore, the two clamping blocks move away from each other, causing the two arc plates to approach each other. When the packaging bag has a harder plastic-sealed edge, a medium-strength suction force is used to adsorb the front and rear walls of the packaging bag, and then the two arc plates are brought closer to each other, so that the packaging bag can be more easily formed into a nearly circular structure, which is conducive to efficient packaging of this type of packaging bag. There is no need to increase the adsorption strength, and the packaging bag with a harder plastic-sealed edge can be efficiently opened at the side, and the use effect is better.

[0020] In addition, the packaging bag is adsorbed by using the long strip opening, so that the adsorption effect on the side of the packaging bag is better, which is beneficial to the subsequent filling. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] See also Figure 1-Figure 7 , a side-opening bag-feeding type packaging machine, comprising a device box 1, and also comprising:

[0042] A top plate 3 is provided on the top of the device box 1 through a bracket, and a feed opening 4 corresponding to one of the clamping components is provided on the top plate 3 .

[0043] The first driving component 6 includes a first motor 601 installed inside the device box 1, and the output end of the first motor 601 is connected to the first rotating shaft 602, and the outer part of the first rotating shaft 602 is sleeved with a first gear 603; the first driving component 6 also includes a second rotating shaft 604 rotatably connected to the inside of the device box 1, and the top end of the second rotating shaft 604 is connected to the bottom center of the turntable 2, and the second rotating shaft 604 is sleeved with a second gear 605 that meshes with the first gear 603.

[0044] The side-opening bag assembly 5 also includes an annular block 501 fixed at the top center of the turntable 2 and an installation box 502 located at the center of the annular block 501, and also includes a negative pressure pump 503 fixed at the top of the turntable 2, the input end of the negative pressure pump 503 is connected to an air inlet pipe 504, and the other end of the air inlet pipe 504 is connected to the interior of the installation box 502; an arc-shaped cavity 505 corresponding to the clamping assembly is opened in the annular wall of the annular block 501, and the interior of the arc-shaped cavity 505 is connected to the interior of the fixed box through a branch pipe 506, and an electromagnetic valve is installed on the branch pipe 506.

[0045] An opening 508 is formed at one end of the clamping block 507 , and a branch hole 509 communicating with the opening 508 is formed inside the clamping block 507 . An air intake pipe 510 for communicating the inside of the branch hole 509 with the inside of the arc-shaped cavity 505 is connected to the clamping block 507 .

[0046] The second driving assembly 7 includes a second motor 701 installed on the top of the device box 1, and the output end of the second motor 701 is connected to the second motor 701, the output end of the second motor 701 is connected to a bidirectional threaded rod 703, and two threaded blocks 702 are symmetrically arranged on the bidirectional threaded rod 703, the two threaded blocks 702 are connected to the bidirectional threaded rod 703 through threaded rotation, and the tops of the two threaded blocks 702 are fixedly connected to the bottoms of the two clamping blocks 507 one by one.

[0047] The driving assembly further includes a guide rod 704 fixed to the top of the turntable 2, and two guide blocks 705 are sleeved on the guide rod 704, and the tops of the two guide blocks 705 are respectively fixedly connected to the bottoms of the two clamping blocks 507 one by one;

[0048] Specifically, when in use, the packaging bag is placed between the two clamping blocks 507, and then the solenoid valve on the branch pipe 506 corresponding to the clamping block 507 is started, and the negative pressure pump 503 is started at the same time, and the negative pressure pump 503 generates negative pressure on the air inlet pipe 504, so that after passing through the installation box 502, the branch pipe 506, the arc cavity 505 and the suction pipe 510, negative pressure is generated at the opening 508 of the two clamping blocks 507, and then negative pressure is generated on the packaging bag between the two clamping blocks 507; in this way, by controlling the opening and closing of the solenoid valve on the branch pipe 506, it is possible to realize adsorption or non-adsorption of the packaging bag on the specified clamping block 507;

[0049] Then, after the packaging bag is adsorbed, the second motor 701 in the second driving assembly 7 corresponding to the clamping assembly is started to rotate the bidirectional threaded rod 703. The rotation of the bidirectional threaded rod 703 causes the two threaded blocks 702 to move relative to each other or move away from each other, thereby causing the two clamping blocks 507 to move relative to each other or move away from each other, thereby completing the side opening of the packaging bag. At the same time, the guide rod 704 and the guide block 705 are arranged to make the two clamping blocks 507 more stable when moving relative to each other, and the use effect is better.

[0050] After the packaging bag is opened on the side, the first motor 601 in the first driving assembly 6 is driven to rotate the first shaft 602, which drives the first gear 603 to rotate, and then the second gear 605 drives the second shaft 604 to rotate, and the second shaft 604 drives the turntable 2 to rotate, so that the packaging bag after the side opening is rotated to the bottom of the discharge port 4, and the packaging bag is filled with materials through the discharge port 4. After the filling is completed, the turntable 2 is rotated again, so that the packaging bag can proceed to the next plastic sealing step (the plastic sealing structure is a prior art and is not shown in the figure), thereby completing the packaging;

[0051] It is worth mentioning that when the second driving assembly 7 is used to open the packaging bag sideways, the two clamping blocks 507 move away from each other, which can drive the first connecting rod 11 to move toward the inside of the first fixed box 8, thereby causing the first piston 10 inside the first fixed box 8 to move. The oil circuits between the first fixed box 8 and the second fixed box 9 are interconnected through the connecting pipe 15. Therefore, the movement of the first piston 10 at this time can cause the second piston 12 inside the second fixed box 9 to drive the second connecting rod 13 and the arc plate 14 to move toward the clamping block 507, thereby squeezing the plastic seal on the side of the packaging bag between the clamping blocks 507. Therefore, by moving the two clamping blocks 507 away from each other and bringing the two arc plates 14 closer to each other, the packaging bag can be more easily formed into a nearly circular structure, which is beneficial to the later packaging of materials and has a better use effect.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
