Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging, and particularly relates to an anti-sleeve bagging device. Background Art

[0002] An automatic bagging machine can automatically put a packaging bag on the outside of a product, and is widely used in industries such as oil chemical industry, granular powder, paint, aquatic products, etc. The automatic bagging machine includes a film guiding process, a film feeding process, a heat sealing process, a cutting process, a film clamping process, a film stretching process, and a lifting process, which complete the automatic conveying of the packaging bag film, sealing, and the automatic conveying and bagging of the product. The bagging machine can be divided into a positive-sleeve bagging machine and an anti-sleeve bagging machine. The positive-sleeve bagging means putting the bottom of the bag into the box body and then putting the bag mouth on the outer periphery of the box mouth; while the anti-sleeve bagging is to put the bag mouth on the outer periphery of the box mouth and then blow the bag bottom reversely into the box body.

[0003] In the prior art, generally, a clamping jaw is used to open the bag mouth to form a square bag mouth, and then it is directly put on the outer periphery of the box mouth of the box body. However, this bagging method still has the following deficiencies in the bagging process:

[0004] 1. After the clamping jaw opens the bag mouth, since the film bag is made of a soft material, the bag mouth will be deformed. In order to smoothly put the bag mouth on the outside of the box body, the perimeter of the bag mouth needs to be more than 150 mm longer than the perimeter of the box body to ensure that the bag mouth does not scratch the box body during the bagging process and avoid not being able to put it into the box body; thus, the production and manufacturing cost of the film bag is increased.

[0005] 2. When the clamping jaw clamps the film bag, the bag mouth of the film bag will fold inward due to the film clamping effect, resulting in unnecessary waste and affecting the subsequent bag mouth sucking and lifting at the bag lifting and film sealing station.

[0006] 3. When the clamping jaw directly clamps the film for bagging, it is very difficult to make the four sides of the film bag flat and beautiful. In the subsequent loading process, it is easy to bring the bag mouth of the bagged film bag into the box body, making the subsequent bag lifting and sealing process unable to be automated, and it is necessary to manually pull out the bag mouth brought into the box body and re-organize it, affecting the production efficiency. Content of the Utility Model

[0007] In order to solve the deficiencies of the above-mentioned prior art, the utility model provides an anti-sleeve bagging device, which avoids the problem that since the film bag is made of a soft material, the bag mouth will be deformed, and in order to smoothly put the bag mouth on the outside of the box body, the perimeter of the bag mouth needs to be more than 150 mm longer than the perimeter of the box body; at the same time, it also avoids the problem that the bag mouth will fold inward due to the film clamping effect, affecting the subsequent bag lifting and film sealing.

[0008] The technical effect to be achieved by the utility model is realized through the following technical solutions:

[0012] The film-supporting mechanism is slidably connected to the guide frame and is located below the film-clamping mechanism. The film-supporting mechanism includes a film-supporting connector, a film-supporting assembly and a rotating drive component. The film-supporting connector is slidably connected to the guide frame, the film-supporting assembly is connected to the side of the film-supporting connector close to the active area, and the power output end of the rotating drive component is connected to the film-supporting assembly.

[0013] In some implementations, the membrane support assembly includes a first connecting plate and a membrane support plate, the first connecting plate is connected to the membrane support connector, and the membrane support plate is connected to a surface of the first connecting plate close to the active area.

[0014] In this implementation, the rotary driving member drives the film-supporting plate to rotate relative to the first connecting plate, so that the film-supporting plate switches between a film-supporting state and a stationary state.

[0015] In some implementations, the first connecting plate is provided with a first connecting hole, the membrane support plate is connected to the first connecting hole, and the first connecting hole is a waist-shaped hole.

[0016] In this implementation, since the first connecting hole is a waist-shaped hole, the installation position of the film support plate on the first connecting hole can be adjusted, thereby adjusting the position of the film support plate relative to the film bag, so as to better adapt to film bags of different specifications and sizes.

[0017] In some implementations, two membrane-supporting plates are provided, and the two membrane-supporting plates are movably arranged on a surface of the first connecting plate close to the movable area.

[0018] In this implementation, the two film-supporting plates correspond to the two film-supporting plates of the oppositely arranged film-supporting mechanism, and jointly open the film bag to keep the surrounding walls of the film bag flat, so that it can be smoothly inserted into the outer periphery of the box opening of the box body.

[0019] In some implementations, the membrane support plate includes a first membrane support wall, a second membrane support wall, and a third membrane support wall. The first membrane support wall is connected to the first connecting hole, the second membrane support wall is connected to the first membrane support wall and extends obliquely toward the active area, and the third membrane support wall is connected to the end of the second membrane support wall facing away from the first membrane support wall.

[0020] In some implementations, the third film-supporting wall has a film-supporting portion and a guiding portion. The guiding portion is connected to one end of the second film-supporting wall facing away from the first film-supporting wall, and the film-supporting portion is connected to the guiding portion. The width of the film-supporting portion in the extending direction of the film-supporting plate is greater than the width of the guiding portion in the extending direction of the film-supporting plate.

The film-clamping connecting piece is fixedly connected to the upper section of the guiding frame, and the film-clamping assembly is connected to one side of the film-clamping connecting piece close to the active area through the telescopic assembly.

[0022] In this implementation, the two telescopic assemblies expand and contract, so that the two relatively arranged film-clamping assemblies expand and contract relative to the active area, enabling the two relatively arranged film-clamping assemblies to extend into or away from the active area.

[0023] In some implementations, the telescopic assembly includes a telescopic rod and a telescopic driving member. The telescopic rod is respectively disposed through the film-clamping connecting piece and the film-clamping assembly, and the telescopic driving member is used to drive the telescopic rod to expand and contract.

[0024] In some implementations, the film-clamping assembly includes a second connecting plate and clamping jaws.

[0028] In summary, the present utility model has at least the following advantages:

[0029] The reverse bagging device provided by the present invention has a film-supporting mechanism provided below the film-clamping mechanism. When the film-clamping mechanism stretches the film strip to form a film bag, the film-supporting component of the film-supporting mechanism stretches the film bag to keep the four sides of the film bag flat, which facilitates the film bag to be smoothly put on the outer periphery of the box opening of the box body. This avoids the problem that the bag opening will be deformed due to the film bag being made of soft material, and the circumference of the bag opening needs to be more than 150mm larger than the circumference of the box body in order to smoothly put the bag opening on the outside of the box body. At the same time, it also avoids the problem that the bag opening will fold inwards due to the film clamping effect, which affects the bag lifting and film sealing in the later stage, thereby ensuring the full automation of bagging, bag lifting and film sealing, and further improving production efficiency.

[0041] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are some, but not all, of the embodiments of the present utility model.

[0042] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0043] Embodiment 1:

[0044] Please refer to the attached Figure 1 ~attached Figure 2 , the anti-sleeved bag device of the present utility model includes a guiding mechanism 1, a film clamping mechanism 2 and a film support mechanism 3.

[0045] Among them, please combine Figure 1 and Figure 2 , Figure 1 shows the structural relationship among the guiding mechanism 1, the film clamping mechanism 2 and the film support mechanism 3 in the embodiment of the present utility model, Figure 2 shows the specific structure of the film support mechanism 3 in the embodiment of the present utility model. Specifically, the guiding mechanism 1 includes two oppositely arranged guiding frames 11, and an activity area 12 is formed between the two guiding frames 11; the film clamping mechanism 2 is connected to the upper section of the guiding frame 11 and is used to pull open the film strip; the film support mechanism 3 is slidably connected to the guiding frame 11 and is located below the film clamping mechanism 2. The film support mechanism 3 includes a film support connecting piece 31, a film support assembly 32 and a rotary drive part 33. The film support connecting piece 31 is slidably connected to the guiding frame 11, the film support assembly 32 is connected to one side of the film support connecting piece 31 close to the activity area 12, and the power output end of the rotary drive part 33 is connected to the film support assembly 32.

[0046] In this embodiment, two film clamping mechanisms 2 are respectively connected to the upper sections of two guiding frames 11, and are used to pull the film belt transferred from the previous working station into a square bag mouth to form a film bag. Two film supporting mechanisms 3 are respectively slidably connected to the two guiding frames 11, and are used to expand the film bag, so that the film bag is unfolded, and further make the four sides of the film bag flat. Specifically, after the film clamping mechanism 2 pulls open the film belt, the rotation driving member 33 of the film supporting mechanism 3 drives the film supporting assembly 32 to rotate, so that the film supporting assembly 32 extends along the inner peripheral wall of the film belt, that is, the film supporting assembly 32 closely adheres to the inner peripheral wall of the film bag to expand the film bag, thereby ensuring the flatness of the film bag. The film supporting connecting member 31 descends along the guiding frame 11, and then drives the film supporting assembly 32 to descend. The film supporting assembly 32 descends to the bag sleeving working station. At this time, the bag mouth of the film bag sleeves the box body. The rotation driving member 33 drives the film supporting assembly 32 to rotate, so that the film supporting assembly 32 is parallel to the peripheral edge of the bag mouth. Then the film supporting connecting member 31 ascends along the guiding frame 11, and the rotation driving member 33 drives the film supporting assembly 32 to rotate again, so that the film supporting assembly 32 expands the film bag, and this process circulates continuously; because the film supporting assembly 32 expands the film bag, it can avoid the problem that in order to ensure that the film bag can be smoothly sleeved on the outer periphery of the box mouth of the box body, the perimeter of the bag mouth needs to be more than 150 mm longer than the perimeter of the box body.

[0047] Furthermore, it further includes a lifting driving member 13, which is used to drive the film supporting mechanism 3 to lift along the guiding frame 11, thereby improving the reliability of the overall structure.

[0048] For the above-mentioned reverse-sleeving bagging device, since the film supporting mechanism 3 is arranged below the film clamping mechanism 2, when the film clamping mechanism 2 pulls open the film belt into a film bag, the film supporting assembly 32 of the film supporting mechanism 3 expands the film bag, so that the four sides of the film bag are kept flat, which is convenient for smoothly sleeving the film bag on the outer periphery of the box mouth of the box body; it avoids the problem that since the film bag is made of a soft material, the bag mouth will be deformed, and in order to smoothly sleeve the bag mouth to the outside of the box body, the perimeter of the bag mouth needs to be more than 150 mm longer than the perimeter of the box body; at the same time, it also avoids the problem that due to the film clamping effect, the bag mouth will fold inwards, affecting the subsequent bag lifting and film sealing, ensuring the full automation of bag sleeving, bag lifting and film sealing, and further improving the production efficiency.

[0049] In some preferred embodiments, the film support assembly 32 includes a first connecting plate 321 and a film support plate 322. The first connecting plate 321 is connected to the film support connector 31, and the film support plate 322 is connected to the side of the first connecting plate 321 near the active area 12. The rotary drive member 33 drives the film support plate 322 to rotate relative to the first connecting plate 321, so that the film support plate 322 switches between a film support state and a static state. In the film support state, the film support plate 322 is perpendicular to the first connecting plate 321 to open the film bag. In the static state, the film support plate 322 is parallel to the first connecting plate 321, preventing the film support plate 322 from scratching the film bag when the film support assembly 32 rises along the guide frame 11. This further prevents the film support plate 322 from damaging the film bag and affecting the bagging effect. It is understood that the film support plate 322 can be connected to the first connecting plate 321 by screwing, crimping, welding, or clamping.

[0050] In some preferred embodiments, please continue to see Figure 2 The first connecting plate 321 is provided with a first connecting hole 3211, and the membrane support plate 322 is connected to the first connecting hole 3211, and the first connecting hole 3211 is a waist-shaped hole. This makes the connection between the membrane support plate 322 and the first connecting plate 321 more stable and improves the compactness of the overall structure. Since the first connecting hole 3211 is a waist-shaped hole, the position of the membrane support plate 322 relative to the membrane bag can be adjusted by adjusting the installation position of the membrane support plate 322 on the first connecting hole 3211, so as to better adapt to membrane bags of different specifications and sizes. Preferably, the connection between the membrane support plate 322 and the first connecting plate 321 is provided with an external thread, and the first connecting hole 3211 is provided with a threaded surface matching the external thread, so that the membrane support plate 322 is screwed to the first connecting plate 321. Of course, bolts can also be passed through the membrane support plate 322 and the first connecting hole 3211 at the same time to connect the membrane support plate 322 and the first connecting plate 321 together.

[0051] In some preferred embodiments, two film-supporting plates 322 are provided, and the two film-supporting plates 322 are movably arranged on a surface of the first connecting plate 321 near the movable area 12. The two film-supporting plates 322 are arranged corresponding to the two film-supporting plates 322 of the film-supporting mechanism 3 arranged opposite to each other, and together they support the film bag to keep the surrounding walls of the film bag flat, so that the film bag can be smoothly inserted into the outer periphery of the box opening.

[0052] Example 2:

[0053] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the reverse bagging device of the utility model. Figure 3 ~Attached Figure 5 .

[0054] Please combine Figure 3 and Figure 4 ,Figure 3 and Figure 4 The diagram illustrates the structural relationship between the first membrane support wall 3221, the second membrane support wall 3222, and the third membrane support wall 3223 in an embodiment of the present invention. Specifically, the membrane support plate 322 includes the first membrane support wall 3221, the second membrane support wall 3222, and the third membrane support wall 3223. The first membrane support wall 3221 is connected to the first connection hole 3211, the second membrane support wall 3222 is connected to the first membrane support wall 3221 and extends obliquely toward the active area 12, and the third membrane support wall 3223 is connected to the end of the second membrane support wall 3222 facing away from the first membrane support wall 3221.

[0055] In this embodiment, since the second film support wall 3222 extends obliquely toward the active area 12, the third film support wall 3223 can more easily enter the interior of the film bag, thereby making the inner wall of the film bag fit to the side of the third film support wall 3223 facing away from the active area 12, and then the bag opening slides along the third film support wall 3223 until it is abutted by the second film support wall 3222, avoiding the problem of scratching between the bag opening and the first connecting plate 321, and further ensuring the reliability of the film support mechanism 3.

[0056] In some preferred embodiments, see Figure 5 , Figure 5 The diagram illustrates the structural relationship between the film support portion 322a and the guide portion 322b in an embodiment of the present invention. Specifically, the third film support wall 3223 includes a film support portion 322a and a guide portion 322b. The guide portion 322b is connected to the end of the second film support wall 3222 facing away from the first film support wall 3221. The film support portion 322a is connected to the guide portion 322b. The width of the film support portion 322a in the direction in which the film support plate 322 extends is greater than the width of the guide portion 322b in the direction in which the film support plate 322 extends. The film support portion 322a is used to open the film bag. After the film bag is opened, the bag mouth slides along the guide portion 322b. Because the width of the film support portion 322a is greater than the width of the guide portion 322b, the film support portion 322a can hook the film bag when the film support mechanism 3 descends, preventing the film bag from falling, thereby improving the reliability of the film support plate 322.

[0057] Example 3:

[0058] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the reverse bagging device of the utility model. Figure 6 ~Attached Figure 7 , Figure 6 The specific structure of the film clamping mechanism 2 in the embodiment of the present utility model is schematically shown.

[0059] Among them, the film clamping mechanism 2 includes a film clamping connector 21, a film clamping assembly 22 and a telescopic assembly 23. The film clamping connector 21 is fixedly connected to the upper section of the guide frame 11, and the film clamping assembly 22 is connected to the side of the film clamping connector 21 close to the active area 12 through the telescopic assembly 23.

[0060] In this embodiment, the two telescopic components 23 are telescopic so that the two oppositely arranged film clamping components 22 are telescopic relative to the active area 12. The two oppositely arranged film clamping components 22 extend into the active area 12, and after clamping the film strip, the two telescopic components 23 retract, driving the two oppositely arranged film clamping components 22 to move relative to each other at the same time, away from the active area 12, and then pulling the film strip into a square bag mouth to form a film bag.

[0061] In some preferred embodiments, the telescopic assembly 23 includes a telescopic rod 231 and a telescopic driver 232. The telescopic rod 231 is respectively disposed through the membrane connector 21 and the membrane assembly 22. The telescopic driver 232 is used to drive the telescopic rod 231 to extend and retract. The telescopic driver 232 drives the telescopic rod 231 to extend and retract, causing the membrane assembly 22 to extend and retract relative to the membrane connector 21, thereby causing the membrane assembly 22 to extend and retract relative to the active area 12, thereby stretching the membrane strip and forming a membrane pocket. Preferably, the telescopic rod 231 can be a linear bearing, which primarily consists of a bearing outer ring, a retainer, steel balls, and a sealing ring. The steel balls circulate along the track groove formed by the bearing outer ring and the retainer, causing the linear bearing to perform linear reciprocating motion relative to the guide shaft. The rolling of the steel balls can achieve high-efficiency motion with low friction resistance.

[0062] In some preferred embodiments, the membrane clamping assembly 22 includes a second connecting plate 221 and a clamping jaw 222. The second connecting plate 221 is connected to the membrane clamping connector 21 through a telescopic assembly 23, and the clamping jaw 222 is connected to the side of the second connecting plate 221 close to the active area 12. The clamping jaw 222 is used to clamp the membrane strip, and the second connecting plate 221 is telescopic to drive the clamping jaw 222 to telescope so as to pull the membrane strip apart. Furthermore, the second connecting plate 221 is provided with a second connecting hole 2211, and the clamping jaw 222 is connected to the second connecting hole 2211. The second connecting hole 2211 is a waist-shaped hole. This makes the connection between the clamping jaw 222 and the second connecting plate 221 more stable and improves the compactness of the overall structure. Since the second connecting hole 2211 is a waist-shaped hole, the position of the clamping jaw 222 relative to the membrane bag can be adjusted by adjusting the installation position of the clamping jaw 222 on the second connecting hole 2211, so as to better adapt to membrane bags of different specifications and sizes. Preferably, the connection between the clamping jaw 222 and the second connecting plate 221 is provided with an external thread, and the second connecting hole 2211 is provided with a threaded surface matching the external thread, so that the clamping jaw 222 is screwed to the second connecting plate 221. Of course, bolts can also be provided through both the clamping jaw 222 and the second connecting hole 2211 to connect the clamping jaw 222 and the second connecting plate 221 together.

[0063] In some preferred embodiments, there are two clamping jaws 222, and the two clamping jaws 222 are movably arranged on one side of the second connecting plate 221 close to the activity area 12. The two clamping jaws 222 are correspondingly arranged with the two clamping jaws 222 of the film clamping mechanism 2 arranged oppositely, and jointly pull the film belt to form a square bag opening of the film belt, so as to facilitate the film supporting mechanism 3 to expand the film bag.

[0064] In some more preferred embodiments, please continue to refer to Figure 6 , the film clamping mechanism 2 further includes a bag blowing assembly 24, the bag blowing assembly 24 is connected to the second connecting plate 221 and extends into the activity area 12, and the opening of the bag blowing assembly 24 is arranged upward. After the film clamping mechanism 2 pulls the film belt, the bag blowing assembly 24 blows air into the inside of the film bag to make the film bag expand more quickly, thereby ensuring the flatness of the four sides of the film bag.

[0065] Please refer to the appendix Figure 7 , Figure 7 which shows the structural relationship among the film clamping mechanism 2, the film supporting mechanism 3 and the film bag in the anti-sleeved bag device in the film supporting state in the embodiment of the present invention.

[0066] In the anti-sleeved bag device of the present invention, since the film supporting mechanism 3 is arranged below the film clamping mechanism 2, when the film clamping mechanism 2 pulls the film belt into a film bag, the film supporting assembly 32 of the film supporting mechanism 3 expands the film bag to keep the four sides of the film bag flat, so as to facilitate the smooth sleeving of the film bag on the outer periphery of the box opening of the box body; it avoids the problem that since the film bag is made of a soft material, the bag opening will be deformed, and in order to smoothly sleeve the bag opening on the outside of the box body, the perimeter of the bag opening needs to be more than 150 mm longer than the perimeter of the box body; at the same time, it also avoids the problem that due to the film clamping action, the bag opening will fold inwards, affecting the subsequent bag lifting and film sealing, ensuring the full automation of bag sleeving, bag lifting and film sealing, and further improving the production efficiency.

[0067] In the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0068] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0069] In addition, terms such as "horizontal", "vertical", "hanging", etc. do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

Moreover, the first feature being above, over, and on the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being below, under, and beneath the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0071] Although the description of the present utility model is made in conjunction with the above specific embodiments, it is obvious that those skilled in the art can make many substitutions, modifications, and changes based on the above content.
