Description

Technical Field

[0001] The present invention belongs to the technical field of plastic bag production, and in particular relates to a plastic bag production system with a flat plastic bag assembly. Background Art

[0002] Plastic bags are bags made of commonly used plastics such as polypropylene, polyester, nylon, etc. They are essential items in people's daily lives and are often used to hold other items. They are widely used because of their low price, extremely light weight, large capacity, and easy storage. However, due to the disadvantages of extremely long degradation cycle and difficult handling, some countries prohibit their production and use. Degradable plastic bags are developed on the basis of plastic bags. Degradable plastic bags will not decompose harmful substances and are very convenient to use. They have been widely used in many industries. In the production process of degradable plastic bags, plastic bags are prone to wrinkles, so plastic bags are generally flattened before leaving the factory.

[0003] The prior art discloses a degradable plastic bag production equipment with the function of flattening plastic bags, application number: 202121728230.1. The degradable plastic bag production equipment with the function of flattening plastic bags is equipped with a first hot air blowing mechanism, a second hot air blowing mechanism, a fixed pressure roller and an adjustable pressure roller. The first hot air blowing mechanism and the second hot air blowing mechanism can blow hot air on both sides of the plastic bag before rolling the degradable plastic bag, so that the plastic bag becomes softened by heat, which facilitates the pressure roller to shape the plastic bag, so that the plastic bag has a better flattening effect. By arranging a spacing adjustment component and an adjustable pressure roller, a person can realize horizontal movement of the adjustable pressure roller by operating the spacing adjustment component, thereby realizing the adjustment of the spacing between the adjustable pressure roller and the fixed pressure roller, so as to adapt to the leveling needs of plastic bags of different thicknesses and other plastic products, thereby improving the flexibility and scope of application of the utility model.

[0004] However, the existing technology still has the following shortcomings: the above device is implemented by using rollers with adjustable spacing to flatten plastic bags of different thicknesses. However, since there are many wrinkles in the production of plastic bag belts, the flattening quality is low by a single compaction method. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a plastic bag production system having a flattened plastic bag assembly, which can reduce wrinkles in the plastic bag by setting a flattening roller to press down the plastic bag and move it to both sides of the plastic bag for flattening.

[0006] The purpose of this disclosure can be achieved through the following technical solutions:

[0007] A plastic bag production system having a flat plastic bag assembly, comprising:

[0008] A rotating table, wherein the lower end of the rotating table is fixedly connected to a first rotating shaft, the lower end of the first rotating shaft is fixedly connected to an intermittent rotating disk, four evenly distributed sliding grooves are opened on the intermittent rotating disk along the circumference, a driving rod is arranged around the circumference of the intermittent rotating disk, and one end of the driving rod is fixedly connected to a gear rod adapted to the sliding groove;

[0009] Two second rotating shafts are symmetrically arranged at the upper end of the rotating table, both ends of the second rotating shafts are fixedly connected with sleeves, a sliding rod is slidably connected in the sleeve, the upper end of the sliding rod is fixedly connected with a connecting block, a leveling roller is rotatably connected between the two connecting blocks, and a spring is sleeved on the outer side of the sliding rod.

[0010] The above technical solution, its principle and technical effect:

[0011] The plastic bag is laid flat on the rotating table, and the driving source drives the other end of the driving rod to rotate, so that the gear rod rotates around the other end of the driving rod. When the gear rod slides into one of the slide grooves and leaves the slide groove, the intermittent turntable rotates a quarter of a circle, thereby driving the rotating table to rotate a quarter of a circle. At the same time, the driving circle drives the two second rotating shafts to rotate in the opposite direction, so that the two smoothing rollers rotate in the opposite direction around their respective corresponding second rotating shafts. When the two smoothing rollers contact the plastic bag, the spring contracts, and the elastic force of the spring gives the smoothing roller a downward pressure. The two smoothing rollers move to both sides of the plastic bag to smooth the plastic bag. That is, every time the rotating table rotates a quarter of a circle, the two smoothing rollers smooth the plastic bag once.

[0012] Furthermore, a workbench is provided at the lower end of the rotating table, the workbench is rotatably connected to the first rotating shaft, and legs are fixedly connected to the circumference of the workbench.

[0013] Furthermore, a first motor is fixedly connected to the lower end of the workbench, and an output end of the first motor is fixedly connected to the other end of the driving rod.

[0014] Furthermore, two ends of the second rotating shaft are fixedly connected with support rods, and the lower ends of the support rods are fixedly connected to the workbench.

[0015] Furthermore, the same side ends of the two second rotating shafts are fixedly connected with a first bevel gear, the first bevel gear is meshed with a second bevel gear, a third rotating shaft is fixedly connected between the two second bevel gears, the third rotating shaft is fixedly connected with a first gear, the first gear is meshed with a second gear, and the second gear is fixedly connected to the output end of the second motor.

[0016] Furthermore, the lower end of the second motor is fixedly connected to a fixing plate, and both ends of the fixing plate are fixedly connected to the support rod.

[0017] Furthermore, both ends of the third rotating shaft are rotatably connected with ear plates, and the lower ends of the ear plates are fixedly connected to the fixing plate.

[0018] Furthermore, the distance between the rotating platform and the first rotating shaft is smaller than the distance between the first rotating shaft and the smoothing roller.

[0019] Furthermore, the double distance between the first rotating shaft and the smoothing roller is smaller than the distance between the two first rotating shafts.

[0020] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0021] Fixed connection refers to a connection in which parts or components are fixed without any relative movement. There are two types of connection: detachable and non-detachable.

[0022] (1) A removable connection is a connection that uses screws, splines, wedge pins, etc. to hold parts together. This type of connection can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0023] (2) Non-detachable connections mainly refer to welding, riveting and tenoning. Since they need to be disassembled by forging, sawing or oxygen cutting for maintenance or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.).

[0024] A threaded connection refers to a detachable connection in which the connected parts are connected together using threaded parts (or the threaded parts of the connected parts).

[0025] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0026] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0027] Beneficial effects of the present disclosure:

[0028] The plastic bag is pressed down by the provided smoothing rollers and moved to both sides of the plastic bag for smoothing, thereby reducing wrinkles on the plastic bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] In the description of the present disclosure, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present disclosure.

[0037] According to the concept of this application, Figures 1 to 5 The embodiment of the plastic bag production system with a flat plastic bag assembly is described below. Specifically, the plastic bag production system with a flat plastic bag assembly is constructed as a split structure, which has a rotating table 1, an intermittent rotating disk 3, a second rotating shaft 7, a spring 12, a flattening roller 11 and other structures that cooperate with each other. The plastic bag is laid flat on the rotating table 1, and the driving source drives the other end of the driving rod 5 to rotate, so that the gear rod 6 rotates around the other end of the driving rod 5. When the gear rod 6 slides into one of the chutes 4 and leaves the chutes 4, at this time, the intermittent rotating disk 3 rotates a quarter of a circle, thereby driving the rotating table 1 to rotate a quarter of a circle. At the same time, the driving circle drives the two second rotating shafts 7 to rotate in the opposite direction, so that the two flattening rollers 11 rotate in the opposite direction around their respective corresponding second rotating shafts 7. When the two flattening rollers 11 contact the plastic bag, the spring 12 contracts, and the elastic force of the spring 12 gives the flattening roller 11 a downward pressure, and the two flattening rollers 11 move to the two sides of the plastic bag to flatten the plastic bag, that is, after each quarter of a circle of the rotating table 1, the two flattening rollers 11 flatten the plastic bag once.

[0038] like Figure 1-5As shown, a plastic bag production system with a flat plastic bag assembly comprises:

[0039] A rotating table 1, a first rotating shaft 2 is fixedly connected to the lower end of the rotating table 1, an intermittent rotating disk 3 is fixedly connected to the lower end of the first rotating shaft 2, four evenly distributed slide grooves 4 are opened on the intermittent rotating disk 3 along the circumference, a driving rod 5 is arranged around the intermittent rotating disk 3, and a gear rod 6 adapted to the slide groove 4 is fixedly connected to one end of the driving rod 5;

[0040] Two second rotating shafts 7 are symmetrically arranged at the upper end of the rotating table 1, and sleeves 8 are fixedly connected at both ends of the second rotating shafts 7. A slide rod 9 is slidably connected in the sleeve 8. A connecting block 10 is fixedly connected to the upper end of the slide rod 9. A leveling roller 11 is rotatably connected between the two connecting blocks 10, and a spring 12 is sleeved on the outer side of the slide rod 9.

[0041] When in use, the plastic bag is spread flat on the rotating table 1, and the driving source drives the other end of the driving rod 5 to rotate, so that the gear rod 6 rotates around the other end of the driving rod 5. When the gear rod 6 slides into one of the slide grooves 4 and leaves the slide groove 4, at this time, the intermittent turntable 3 rotates a quarter of a circle, thereby driving the rotating table 1 to rotate a quarter of a circle. At the same time, the driving circle drives the two second rotating shafts 7 to rotate in the opposite direction, so that the two smoothing rollers 11 rotate in the opposite direction around their respective corresponding second rotating shafts 7. When the two smoothing rollers 11 contact the plastic bag, the spring 12 contracts, and the elastic force of the spring 12 gives the smoothing roller 11 a downward pressure. The two smoothing rollers 11 move to both sides of the plastic bag to smooth the plastic bag, that is, after each quarter of a circle rotation of the rotating table 1, the two smoothing rollers 11 smooth the plastic bag once.

[0042] It should be noted that when the rotating table 1 rotates, the smoothing roller 11 will not contact the plastic bag. When the rotating table 1 does not rotate, the smoothing roller 11 will contact the plastic bag to perform normal processing on the plastic bag. After each quarter turn of the rotating table 1, the two smoothing rollers 11 smooth the plastic bag once to avoid smoothing only the two sides of the plastic bag.

[0043] In one embodiment of the present invention, a workbench 13 is disposed at the lower end of the rotating table 1, the workbench 13 is rotatably connected to the first rotating shaft 2, and legs 14 are fixedly connected to the peripheral side of the workbench 13 to support the entire device system.

[0044] In one embodiment of the present invention, a first motor 15 is fixedly connected to the lower end of the workbench 13, and an output end of the first motor 15 is fixedly connected to the other end of the driving rod 5. The first motor 15 drives the driving rod 5 to rotate around the output end of the first motor 15, thereby causing the shift rod 6 to rotate around the output end of the first motor 15.

[0045] In one embodiment of the present invention, two ends of the second rotating shaft 7 are fixedly connected with supporting rods 16, and the lower end of the supporting rod 16 is fixedly connected to the workbench 13 to support the second rotating shaft 7 to rotate.

[0046] In one embodiment of the utility model, the same side ends of the two second rotating shafts 7 are fixedly connected with the first bevel gear 17, the first bevel gear 17 is meshed with the second bevel gear 18, the third rotating shaft 19 is fixedly connected between the two second bevel gears 18, the third rotating shaft 19 is fixedly connected with the first gear 20, the first gear 20 is meshed with the second gear 21, and the second gear 21 is fixedly connected to the output end of the second motor 22. The second motor 22 drives the second gear 21 to rotate, the second gear 21 drives the first gear 20 to rotate, the first gear 20 drives the third rotating shaft 19 to rotate, the third rotating shaft 19 drives the two second bevel gears 18 to rotate, the two second bevel gears 18 drive the two first bevel gears 17 to rotate in the opposite direction, and then the two second rotating shafts 7 rotate in the opposite direction.

[0047] In one embodiment of the present invention, the lower end of the second motor 22 is fixedly connected to the fixing plate 23, and both ends of the fixing plate 23 are fixedly connected to the support rod 16. The second motor 22 is fixed.

[0048] In one embodiment of the present invention, both ends of the third rotating shaft 19 are rotatably connected with ear plates 24, and the lower ends of the ear plates 24 are fixedly connected to the fixing plates 23 to support the third rotating shaft 19 to rotate.

[0049] In one embodiment of the present invention, the distance between the rotating platform 1 and the first rotating shaft 2 is smaller than the distance between the first rotating shaft 2 and the leveling roller 11 , so as to ensure that the leveling roller 11 can contact the plastic bag on the rotating platform 1 .

[0050] In one embodiment of the present invention, the double spacing between the first rotating shaft 2 and the smoothing roller 11 is smaller than the spacing between the two first rotating shafts 2, so as to avoid motion interference when the two smoothing rollers 11 are close to each other.
