Description

Technical Field

[0001] The utility model relates to the technical field of enzymes, in particular to an organic enzyme packaging machine. Background Art

[0002] Enzymes are products containing specific biologically active ingredients obtained through microbial fermentation with or without the addition of auxiliary materials from animals, plants, fungi, etc., which contain various active substances, biological enzymes and probiotics, and are rich in nutrition and high economic value. In enzyme production workshops, standard self-supporting bag packaging machines and other packaging equipment are often used to make and package organic enzymes. At present, the existing DS series of standard self-supporting bag packaging machines use a host frequency conversion speed regulation system and servo unloading, which are simple to adjust and have high stability. They use PLC positioning modules to achieve precise positioning and small bag shape errors, and can automatically complete the full automation of packaging processes such as bag making, metering, filling and sealing. After the above-mentioned standard self-supporting bag packaging machine completes the bagging, it is generally through two coaxially symmetrically arranged bag opening nozzles that make synchronous reverse movements through two electric push cylinders or air cylinders, that is, it simultaneously attracts from both sides of the bag opening to open the bag opening for the next step of metering and filling.

[0003] At present, the suction force generated by the bag opening nozzle of the standard self-supporting bag packaging machine is mainly produced by the external vacuum pump of the air guide tube. It is not possible to generate suction and traction at the same time only by moving the push rod in the electric push cylinder. This paper aims to propose an organic enzyme packaging machine that does not require a vacuum pump. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] An organic enzyme packaging machine, comprising an electric push cylinder and a bag opening nozzle, wherein one side of the push rod in the electric push cylinder is connected to a driving rod in parallel and decelerated manner through a deceleration gear set, a convex block is fixedly installed on the right end of the driving rod, a spring in a compressed state is arranged on the left side of the convex block, and a cylinder is pressed and connected to the left end of the spring;

[0008] Preferably, a base plate is fixedly installed on one side of the electric push cylinder, and two mutually parallel guide rails are fixedly installed on the base plate. A slide groove is arranged in the guide rail, and the suction cylinder and the driving rod are respectively slidably installed in the slide grooves in the two guide rails through a T-shaped slide bar.

[0009] Preferably, a round rod is fixedly installed on the left side of the protrusion, the round rod is arranged in the inner circle of the spring, the left end of the round rod is arranged in the cylinder, and the left end of the spring is arranged in the cylinder.

[0010] Preferably, the reduction gear group includes a large gear and a small gear that mesh with each other, and the large gear and the small gear are both rotatably connected to the base plate. The push rod is provided with a sawtooth 1 that meshes with the small gear, and the drive rod is provided with a sawtooth 2 that meshes with the large gear.

[0011] Preferably, a limit block is fixedly mounted on the right end of the cylinder, and the limit block is arranged directly to the right of the guide rail.

[0012] Preferably, a driving block is fixedly mounted on the right end of the cylinder, and the driving block is arranged directly to the right of the protrusion.

[0013] Compared with the prior art, the utility model provides an organic enzyme packaging machine, which has the following beneficial effects:

[0014] The organic enzyme packaging machine connects the movements of the piston at the end of the push rod in the electric push cylinder and the suction cylinder outside the piston in the same direction through the large gear and small gear that mesh with each other in the reduction gear group, and the kinetic energy transmission of the drive rod and the spring, and the movement speed of the piston is greater than the movement speed of the suction cylinder, so that when the suction cylinder moves, the piston can still draw air in the suction cylinder to generate negative pressure suction, so that the suction cylinder can attract the bag opening of the packaging bag through the bag opening nozzle while pulling the bag opening to move. That is, the utility model only generates suction and traction at the same time through the movement of the push rod in the electric push cylinder, and can generate negative pressure to attract the bag opening of the packaging bag without connecting the bag opening nozzle to a vacuum pump.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] Refer to the attached Figure 1-2 An organic enzyme packaging machine includes a bottom plate 1, two mutually parallel guide rails 3 are fixedly installed on both sides of the top of the bottom plate 1, and the inner sides of the two guide rails 3 are provided with slide grooves. The bottom plate 1 is also provided with mutually parallel suction cylinders 4 and driving rods 8, which are arranged in parallel between the two guide rails 3. The suction cylinder 4 and the driving rod 8 are respectively slidably installed in the slide grooves of the two guide rails 3 through T-shaped sliding rods 9, and the two T-shaped sliding rods 9 are respectively fixedly connected with the suction cylinder 4 and the driving rod 8;

[0021] A limit block 6 and a drive block 7 are fixedly installed on the right end of the suction cylinder 4. The limit block 6 is arranged on the right side of the guide rail 3 to limit the distance that the suction cylinder 4 moves to the left. The drive block 7 is arranged on the side close to the drive rod 8. A protrusion 17 is arranged on the left side of the drive block 7. The protrusion 17 is fixedly installed on the right end of the drive rod 8, that is, the drive rod 8 moving to the right can push the right side of the suction cylinder 4 through the protrusion 17 and the drive block 7.

[0022] In this embodiment, a round rod 16 is fixedly installed on the left side of the protrusion 17, and a spring 15 which is always in a compressed state is arranged on the periphery of the round rod 16. The elastic force of the spring 15 is always greater than the sum of the friction forces of the suction cylinder 4 moving to the right. The round rod 16 is mainly used to support the inner ring of the spring 15 to prevent the spring 15 from bending and deforming outward. A cylinder 14 is arranged on the periphery of the left end of the round rod 16, and the left end of the spring 15 is extruded and installed in the cylinder 14. The cylinder 14 is also used to prevent the spring 15 from bending and deforming outward. The cylinder 14 and the suction cylinder 4 are fixedly connected. The spring 15 which is always in a compressed state is mainly used to push the suction cylinder 4 to move to the left until the driving block 7 abuts against the right end of the protrusion 17, or the limit block 6 abuts against the right end position of the guide rail 3.

[0023] In this embodiment, the right end of the suction cylinder 4 is fixedly connected to a bag opening nozzle 5 for a self-supporting bag packaging machine, a piston 18 is slidably installed in the suction cylinder 4, an electric push cylinder 2 is arranged just to the left of the piston 18, the electric push cylinder 2 is fixedly connected to the bottom plate 1, the end of the push rod 12 in the electric push cylinder 2 is fixedly installed on the piston 18, the push rod 12 slides through the left end of the suction cylinder 4, a reduction gear set is arranged between the push rod 12 and the driving rod 8, and the reduction gear set is composed of a large gear 10 and a small gear 11 that mesh with each other, and the large gear 10 and the small gear 11 are arranged on the bottom plate 12. The rotation of the gear 10 and the pinion 11 are both connected to the bottom plate 1. The teeth of the large gear 10 are twice the teeth of the small gear 11, that is, the small gear 11 rotates twice, and the large gear 10 rotates once. One side of the push rod 12 is provided with a sawtooth 13 meshing with the small gear 11, and one side of the driving rod 8 is provided with a sawtooth 2 19 meshing with the large gear 10. The sawtooth 13 on the small gear 11 and the push rod 12 are meshed and connected, and the sawtooth 2 19 on the large gear 10 and the driving rod 8 are meshed and connected.

[0024] From the above, it can be known that the movements of the push rod 12 and the driving rod 8 are linked by the kinetic energy transmission of the mutually meshing large gear 10 and small gear 11, and the sawtooth 1 13 and sawtooth 2 19 on the push rod 12 and the driving rod 8. Whenever the push rod 12 moves, the driving rod 8 will also move in the same direction following the push rod 12. The teeth of the large gear 10 are twice the teeth of the small gear 11. Therefore, when the push rod 12 moves, the distance moved by the push rod 12 is twice that of the driving rod 8.

[0025] The utility model, such as Figure 2, is the initial state of the bag opening nozzle 5 in the organic enzyme packaging machine. The left side of the limit block 6 is pushed by the spring 15 in the compressed state and abuts against the right side of the guide rail 3. The driving block 7 and the protrusion 17 contact each other. At this time, a certain gap is reserved between the end of the bag opening nozzle 5 and the packaging bag whose bag mouth needs to be opened, and the two sides of the packaging bag are provided with symmetrically coaxially arranged bag opening nozzles 5. The bag opening nozzles 5 on both sides of the packaging bag make synchronous reverse movements, that is, the two symmetrical electric push cylinders 2 on both sides of the packaging bag are connected to the controller through wires, which are used to control the two bag opening nozzles 5 to make synchronous reverse movements. The specific process of the organic enzyme packaging machine to open the bag mouth by sucking the bag opening nozzle 5 is as follows:

[0026] 1) At the same time, the push rods 12 in the two electric push cylinders 2 are synchronously extended outward. After the push rods 12 are extended, the push rods 12 directly drive the piston 18 to squeeze and discharge the air in the suction cylinder 4. At the same time as the push rods 12 are extended, the large gear 10 and the small gear 11 that are meshed with each other will also drive the convex block 17 to push the driving block 7 and the suction cylinder 4 to move in the same direction at 1 / 2 speed, squeezing the two bag opening nozzles 5 on both sides of the bag opening of the packaging bag;

[0027] 2) At the same time, the push rods 12 in the two electric push cylinders 2 are synchronously retracted inwards until the limit block 6 on the suction cylinder 4 is against the guide rail 3. When the push rod 12 is retracted, the drive rod 8 also moves in the same direction at a speed of 1 / 2, and the elastic force of the spring 15 in the present application is always greater than the sum of the friction forces of the suction cylinder 4 moving to the right. The moving drive rod 8 can push the suction cylinder 4 to move in the same direction at a speed of 1 / 2 through the convex block 17 and the spring 15 in the compressed state. At this time, the push rod 12 and the piston 18 are synchronously moved, that is, the suction cylinder 4 moves in the same direction at a speed of 1 / 2 of the piston 18, that is, while the two suction cylinders 4 are moving away from each other, the piston 18 is still extracting the air in the suction cylinder 4, causing negative pressure, and the two bag opening nozzles 5 transmit suction force to open the bag opening to both sides, so that the suction cylinder 4 can draw the bag opening of the packaging bag through the bag opening nozzle 5 while also pulling the bag opening to move, and negative pressure can be generated without connecting the bag opening nozzle 5 to an external vacuum pump;

[0028] 3) When the limit block 6 on the suction cylinder 4 is against the guide rail 3, in order to maintain the suction generated by the suction cylinder 4 and the bag opening nozzle 5, the push rods 12 in the two electric push cylinders 2 can continue to be synchronously retracted inward, and the continuously retracted push rods 12 can still drive the piston 18 to move, continue to generate negative pressure, and maintain suction. At this time, the suction cylinder 4 cannot continue to move, and the moving drive rod 8 can only compress the spring 15. If the stability of the suction generated by the bag opening nozzle 5 is to be maintained and excessive suction is avoided, when the suction cylinder 4 stops moving, the retraction speed of the push rod 12 must also be reduced by 1 / 2.

[0029] When releasing the suction force of the bag opening nozzle 5 on the bag mouth of the packaging bag, it is only necessary to extend the push rod 12 in the electric push cylinder 2 in the reverse direction. The moving push rod 12 will compress the air and push the contacting bag body part away until the spring 15 pushes the protrusion 17 to squeeze on the driving block 7 and keep the limit block 6 and the guide rail 3 in contact, that is, the bag opening nozzle 5 is restored to its initial state.

[0030] 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.
