Description

TECHNICAL FIELD

[0001] The present application relates to the field of stand-up pouch processing, in particular to a stand-up pouch processing equipment and processing technology. BACKGROUND

[0002] In the packaging industry, stand-up pouches have become the mainstream packaging form in the fields of food, daily chemicals, medicine, etc. due to their convenient characteristics of not needing to rely on support and being able to stand up whether the bag is opened or not. Such packaging bags are usually composed of two side surfaces and a bottom surface, the bottom surface is folded in half to form an ∧ shape, and most packaging bags are made of plastic material. Edge sealing is a key process in the production of stand-up pouches, which directly determines the sealing performance and structural stability of the packaging bag. If the edge sealing quality is not up to standard, it is easy to cause leakage and deterioration of the contents, so the performance of the edge sealing equipment is crucial to the quality of the stand-up pouch products.

[0003] Due to the ∧ shape of the bottom surface of the stand-up pouch after being folded in half, the edge of the bag body forms a multi-layer material superposition structure, resulting in inconsistent thickness of each region of the edge, some regions being double-layer material and some regions being multi-layer material superposition, with obvious thickness difference. In the edge sealing process, the existing equipment uses uniform edge sealing pressure and temperature parameters for processing, which cannot dynamically adjust according to the thickness difference of different regions of the edge: for the regions with thicker thickness, excessive pressure is easy to cause material overpressure damage, affecting the integrity of the packaging bag; for the regions with thinner thickness, insufficient pressure or temperature makes it difficult to achieve sufficient sealing, which is easy to cause edge leakage, seriously affecting the product qualification rate and use safety. SUMMARY

[0004] Therefore, it is necessary to provide a stand-up pouch processing equipment and processing technology to solve the problem of poor edge sealing effect of the current stand-up pouch.

[0005] The above-mentioned purpose is achieved by the following technical solutions:

[0006] The self-standing bag processing equipment comprises a machine body, an adjusting mechanism, a first edge sealing mechanism and a second edge sealing mechanism. The machine body is provided with a bag material advancing in a first direction. The bag material comprises a bottom surface and two side surfaces. The bottom surface is folded and provided with an included angle facing away from the two side surfaces. The two side surfaces are arranged in a second direction perpendicular to the first direction.

The second sealing plate is slidingly arranged on the machine body and located on the side of the bottom surface of the bag material away from the first sealing plate. The first sealing plate and the second sealing plate can contact the bag material and seal the contact position, so as to separate the bag material into a plurality of self-standing bags arranged in the first direction. The driving assembly is used for controlling the two first sealing plates to clamp the two side surfaces of the bag material, simultaneously controlling the second sealing plate to approach the first sealing plate and contacting the bottom surface of the bag material after the two first sealing plates clamp the bag material. The second edge sealing mechanism is used for bonding the two edges of the self-standing bags arranged in the first direction.

The plurality of rotating discs are located on the side of the included angle of the bottom surface of the bag material, and each rotating disc is inserted into the included angle of the bottom surface. The length of the plurality of rotating discs in the second direction sequentially increases in the first direction. The length of the rotating column in the second direction is greater than the length of the bottom surface in the second direction, and the bottom surface in contact with the rotating column is a plane.

[0008] Preferably, the driving assembly comprises an ear plate, a sliding plate and a buffer part. The ear plate is provided with two ear plates. The ear plate is arranged on the machine body and located on the same side of the bag material in the second direction. The two ear plates are located on the two sides of the first sealing plate in the first direction. The second sealing plate is slidingly arranged on the ear plate in a third direction. The two first sealing plates are slidingly arranged on the ear plate in the second direction and the third direction. The third direction is perpendicular to the first direction and the second direction. The sliding plate is slidingly arranged on the ear plate in the second direction and slidingly connected with the second sealing plate and one of the first sealing plates. When the sliding plate approaches the bag material, the two first sealing plates can approach each other and the first sealing plate and the second sealing plate can approach each other. The driving assembly is provided with two driving assemblies, each corresponding to one first sealing plate. The two driving assemblies are located on the two sides of the bag material in the second direction and rotationally symmetrical about a preset axis. The preset axis extends in the third direction and is located between the two side surfaces of the bag material. The buffer part is used for making the two first sealing plates abut and stationary relative to the bag material.

[0009] Preferably, the machine body is provided with two air cylinders, each air cylinder corresponding to one sliding plate in the driving assembly. The air cylinder can drive the corresponding sliding plate to slide in the second direction.

[0010] Preferably, each buffer includes a guide rod, a slider, and a spring. One end of the guide rod is disposed on the first sealing plate. The slider is sleeved on the guide rod and slidably connected to the guide rod. The spring is sleeved on the guide rod and connects the first sealing plate and the slider. The slider is slidably connected to the slide plate along the second direction and the third direction. When the two first sealing plates abut, the slide plate drives the slider to slide on the guide rod against the elastic force of the spring.

[0011] Preferably, both the first and second sealing plates are provided with heat pipes, which are used to heat the first or second sealing plate.

[0012] Preferably, the two first sealing plates are provided with a clearance groove on the side where they are close to each other, and the two first sealing plates and the second sealing plate are also provided with a clearance groove on the side where they are close to each other.

[0013] Preferably, the stand-up pouch processing equipment also includes a folding mechanism, which is mounted on the machine body and is used to fold the bag material on both sides of the adjusting mechanism and the first sealing mechanism.

[0014] Preferably, the stand-up pouch processing equipment further includes a conveying mechanism for conveying the bag material on the machine body along a first direction and for limiting the bag material.

[0015] A stand-up pouch manufacturing process includes the following steps:

[0016] S1, pass the folded bag material through the adjustment structure.

[0017] S2, the drive assembly controls the first sealing plate to contact the two sides of the bag material and bond the parts of the bag material in contact with it.

[0020] The beneficial effects of this invention are as follows: An adjustment mechanism is provided to unfold the bottom surface of the folded bag material, ensuring that the thickness of the bottom surface is uniform and consistent with the thickness of the sides. A first sealing plate and a second sealing plate are provided to seal the edges of the two sides and the bottom surface of the bag material. The driving assembly controls the sequence of sealing the sides and bottom, ensuring that the two sides closest to the bottom are sealed first, followed by the bottom surface. Because the thickness of the sealed portion of the bag material is consistent when the first or second sealing plate seals, its airtightness is guaranteed. Simultaneously, when the first sealing plate seals the sides of the bag material, the edge of the sealing position tends to bulge, resulting in a tighter fit between the bottom and sides.

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0030] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage" used in this invention, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0032] like Figures 1 to 6As shown, this embodiment of the invention provides a stand-up pouch processing device, including a machine body 100, an adjustment mechanism, a first sealing mechanism, and a second sealing mechanism 121. The machine body 100 has a bag material that moves along a first direction. The bag material includes a bottom surface and two side surfaces. The bottom surface is folded and has an included angle facing away from the two side surfaces. The two side surfaces are arranged along a second direction, which is perpendicular to the first direction. The adjustment mechanism is disposed on the machine body 100 and is used to expand the included angle of the bottom surface. The first sealing mechanism includes a first sealing plate 101, a second sealing plate 102, and a drive assembly. Two first sealing plates 101 are provided, and the two first sealing plates 101 are slidably disposed on the machine body 100 and located on the two side surfaces. On both sides of the second direction, the second sealing plate 102 is slidably disposed on the body 100 and located on the bottom surface of the bag material away from the first sealing plate 101. The first sealing plate 101 and the second sealing plate 102 can contact the bag material and seal the contact position, dividing the bag material into multiple continuous stand-up pouches arranged along the first direction. The drive assembly is used to control the two first sealing plates 101 to clamp the two sides of the bag material and move them closer to the first sealing plate 101, while controlling the second sealing plate 102 to move closer to the first sealing plate 101 and contact the bottom surface of the bag material after the two first sealing plates 101 clamp the bag material. The second sealing mechanism 121 is used to bond the two sides of the stand-up pouch arranged along the first direction. The second sealing mechanism 121 is prior art, which uses high temperature to bond the bottom surface of the stand-up pouch, so that the stand-up pouch can stand up.

[0033] An adjustment mechanism is provided to open the bottom surface of the folded bag material, ensuring that the thickness of the bottom surface is uniform and consistent with the thickness of the sides. A first sealing plate 101 and a second sealing plate 102 are installed to seal the edges of the two sides and the bottom surface of the bag material. The driving component controls the sequence of sealing the sides and bottom, ensuring that the two sides closest to the bottom are sealed first, followed by the bottom surface. Because the thickness of the sealed area is consistent when the first sealing plate 101 or the second sealing plate 102 seals the bag material, its airtightness is guaranteed. Simultaneously, when the first sealing plate 101 seals the sides of the bag material, the edge of the sealing position tends to bulge, resulting in a tighter fit between the bottom and sides.

[0034] In this embodiment, the adjustment mechanism includes a turntable 103 and a rotating column 104. Multiple turntables 103 are provided. The rotating column 104 and multiple turntables 103 are rotatably mounted on the machine body 100 and arranged sequentially along the first direction. The axes of the turntables 103 and the rotating column 104 both extend along the second direction. The multiple turntables 103 are located on the side facing the included angle of the bottom surface of the bag material, and each turntable 103 is inserted into the included angle of the bottom surface. The length of the multiple turntables 103 in the second direction increases sequentially along the first direction. The length of the rotating column 104 in the second direction is greater than the length of the bottom surface in the second direction, and the bottom surface in contact with the rotating column 104 is a plane.

[0035] Specifically, the bottom surface of the folded bag material is ∧-shaped, and the turntable 103 is located in the sandwich of the folded bottom surface. As the bag material moves, the thickness of the turntable 103 gradually increases, and the turntable 103 gradually expands the bag material, increasing the included angle of the bag material. The cross-section of the bag material gradually takes on a T-shape, thereby reducing the maximum number of layers of the bag material in the second direction. Until the bottom surface contacts the rotating column 104, at which point the included angle of the bottom surface is close to a flat angle, and the bottom surface is close to a plane, which facilitates the subsequent approach of the second sealing plate 102 and avoids wrinkles on the bottom surface.

[0036] In this embodiment, the driving assembly includes ear plates 105, a sliding plate 106, and a buffer section. Two ear plates 105 are provided, which are disposed on the body 100 and located on the same side of the bag material in the second direction. The two ear plates 105 are located on both sides of the first sealing plate 101 in the first direction. The second sealing plate 102 is slidably disposed on the ear plates 105 in the third direction. The two first sealing plates 101 are slidably disposed on the ear plates 105 in the second direction and the third direction, respectively. The third direction is perpendicular to the first direction and the second direction. The sliding plate 106 is slidably disposed on the ear plates 105 in the second direction and is slidably connected to the second sealing plate 102 and one of the first sealing plates 101. When the sliding plate 106 approaches the bag material, it can drive the two first sealing plates 101 to approach each other and bring the first sealing plate 101 and the second sealing plate 102 closer together. There are two drive components, each corresponding to a first sealing plate 101. The two drive components are located on both sides of the bag material in the second direction and are rotationally symmetrical about a preset axis. The preset axis extends along a third direction and is located between the two sides of the bag material. The buffer part is used to keep the two first sealing plates 101 stationary relative to the bag material after they come into contact, so as to prevent the first sealing plates 101 from driving the bag material to move.

[0037] Specifically, each ear plate 105 is provided with a first groove 107 and a second groove 108 arranged along a third direction. The first groove 107 extends along the third direction, and the second groove 108 gradually moves away from the bag material from the side close to the first groove 107 to the side away from the first groove 107. The two sides of the second sealing plate 102 arranged along the first direction are respectively provided with two first guide rods 109. Each first guide rod 109 is slidably disposed in a first groove 107 on an ear plate 105. The two sides of each first sealing plate 101 arranged along the first direction are respectively provided with second guide rods 110. Each second guide rod 110 is slidably disposed in a second groove 108 on an ear plate 105 in the corresponding drive assembly.

[0038] Each slide plate 106 is provided with a third slide groove 111 and a fourth slide groove 112, which are arranged along a third direction. The third slide groove 111 extends along the third direction, and the fourth slide groove 112 gradually approaches the bag material from the side closest to the third slide groove 111 to the side furthest from the third slide groove 111. One third slide groove 111 and one fourth slide groove 112 constitute a slide groove group. Each slide plate 106 is provided with two slide groove groups, which are arranged along a first direction. Each first guide rod 109 slides in a fourth slide groove 112, and each second guide rod 110 slides in a third slide groove 111.

[0039] When the slide plate 106 approaches the bag material, the first guide rod 109 can approach the bottom surface of the bag material along a third direction through the cooperation of the first slide groove 107 and the fourth slide groove 112; at the same time, the two first sealing plates 101 can approach each other and approach the second sealing plate 102 through the cooperation of the second slide groove 108 and the third slide groove 111, thereby sealing the bag material.

[0040] Each first sealing plate 101 has positioning posts 113 on two sides arranged along the first direction. The positioning posts 113 and the second guide rods 110 on the same side of the first sealing plate 101 are arranged along the second direction. Each ear plate 105 has a positioning groove 114 that is in the same direction of inclination as the second slide groove 108. The second guide rod 110 is slidably disposed in the positioning groove 114 to prevent the first sealing plate 101 from rotating around the second guide rod 110, thus ensuring the stability of the first sealing plate 101.

[0041] In this embodiment, the body 100 is provided with two cylinders 115, each cylinder 115 corresponds to a slide plate 106 in a drive assembly, and the extension and retraction of the cylinder 115 can drive the corresponding slide plate 106 to slide along the second direction.

[0042] Specifically, cylinder 115 includes a cylinder body and a piston rod. The cylinder body is mounted on the machine body 100. One end of the piston rod is slidably mounted in the cylinder body along the second direction, and the other end is connected to the corresponding slide plate 106. The sliding of the piston rod causes the slide plate 106 to slide.

[0043] In this embodiment, each drive assembly has two buffer sections. Each buffer section includes a guide rod 116, a slider 117, and a spring 118. One end of the guide rod 116 is disposed on the first sealing plate 101. The slider 117 is sleeved on the guide rod 116 and slidably connected to the guide rod 116. The spring 118 is sleeved on the guide rod 116 and connects the first sealing plate 101 and the slider 117. The slider 117 is slidably connected to the slide plate 106 along the second direction and the third direction. When the two first sealing plates 101 abut, the slide plate 106 drives the slider 117 to slide on the guide rod 116 against the elastic force of the spring 118.

[0044] Specifically, the slider 117 is connected to one of the second guide rods 110 on a first sealing plate 101, and the slider 117 is slidably connected to the slide plate 106 via the second guide rod 110. Each first sealing plate 101 has two buffer sections, arranged along a first direction, with each buffer section corresponding to one second guide rod 110 on a first sealing plate 101. The guide rod 116 is inclined, and the inclination direction of the guide rod 116 is consistent with the extension direction of the corresponding second slide groove 108.

[0045] In this embodiment, both the first sealing plate 101 and the second sealing plate 102 are provided with heat pipes. The heat pipes are used to heat the first sealing plate 101 or the second sealing plate 102, and the heated first sealing plate 101 and the second sealing plate 102 can make contact.

[0046] In this embodiment, a clearance groove 119 is provided on the side of the two first sealing plates 101 that are close to each other, and a clearance groove 119 is also provided on the side of the two first sealing plates 101 and the second sealing plate 102 that are close to each other. After the two first sealing plates 101 or the first sealing plate 101 and the second sealing plate 102 come into contact with the bag material, the portion of the bag material outside the clearance groove 119 is bonded together to form a bag with an opening.

[0047] In this embodiment, the stand-up pouch processing equipment also includes a folding mechanism, which is mounted on the machine body 100 and used to fold the bag material on both sides of the adjusting mechanism and the first sealing mechanism. The folding mechanism is a prior art method, used to allow the bottom part of the bag material to enter between the two sides and form a ∧ shape. After folding, the bottom surface has a crease, which can prevent the bottom surface from deviating when the second sealing plate 102 seals the bottom surface.

[0048] Two rotating rollers 120 are provided between the second sealing plate 102 and the second sealing mechanism 121. The two rotating rollers 120 are rotatably mounted on the machine body 100 with their rotation axes extending along a third direction. The two rotating rollers 120 are arranged along a second direction. After the bottom surface of the bag material passing through the first sealing plate 101 and the second sealing plate 102 is folded away from the side, it passes between the two rotating rollers 120. At this time, the bottom surface is folded again to form a ∧ shape. After passing through the second sealing mechanism 121, the two sides of the stand-up pouch arranged along the first direction and the ∧-shaped bottom surface are bonded together, achieving the effect of standing upright and sealing the sides. At the same time, the area at the junction of the bottom sealing and the side sealing of the stand-up pouch has been pre-bonded, so the second sealing mechanism 121 can better bond the remaining unbonded parts when sealing the sides of the stand-up pouch.

[0049] In this embodiment, the stand-up pouch processing equipment further includes a conveying mechanism, which is used to convey the bag material on the machine body 100 along a first direction and limit the position of the bag material. The conveying mechanism is existing technology; it clamps the two sides of the bag material and conveys the bag material, and the clamping force can prevent the bag material from sliding upwards on the third side.

[0050] The working principle of the stand-up pouch processing equipment provided in the above embodiments is as follows:

[0051] First, the first sealing plate 101 and the second sealing plate 102 are heated by heat pipes. Then, the bag material is folded by the folding mechanism on the machine body 100 so that the bottom surface of the bag material is ∧-shaped. Then, the bag material is conveyed along the first direction by the conveying mechanism. The bag material first contacts the thinner turntable 103. The turntable 103 is inserted into the included angle of the bottom surface. As the bag material moves, the bag material contacts multiple turntables 103 in succession. At the same time, the thickness of the turntables 103 increases in sequence, and the included angle of the bottom surface of the bag material is gradually widened until the bottom surface contacts the rotating column 104. The included angle of the bottom surface is close to a flat angle, and the cross-sectional shape of the bag material is approximately T-shaped.

[0052] The conveying mechanism continues to convey the bag material. The side of the bag material comes between the two first sealing plates 101, and the bottom of the bag material comes between the first sealing plate 101 and the second sealing plate 102. Then, the two cylinders 115 are activated simultaneously. The two cylinders 115 drive the corresponding two sliding plates 106 to move closer to each other. The two sliding plates 106 drive the second guide rod 110 to slide in the second sliding groove 108 on the ear plate 105 through the third sliding groove 111. The two first sealing plates 101 move closer to each other and closer to the second sealing plate 102 until they contact the side of the bag material. The high temperature of the first sealing plate 101 causes the two sides of the bag material to stick together. The bag material located in the area of ​​the avoidance groove 119 and outside the area of ​​the first sealing plate 101 is not affected by the temperature.

[0053] After the two first sealing plates 101 compress the bag material, they are no longer moving relative to each other due to the resistance force. Meanwhile, the two sliding plates 106 continue to approach each other. The sliding plates 106, via the second guide rod 110, drive the slider 117 to slide on the guide rod 116 and compress the spring 118. Simultaneously, as the sliding plates 106 approach each other, they drive the first guide rod 109 to slide in the first slide groove 107 via the fourth slide groove 112. The first guide rod 109 then drives the second sealing plate 102 to approach the first sealing plate 101. Only after both first sealing plates 101 have contacted the bag material does the second sealing plate 102 contact the bottom surface. This process continues until the second sealing plate 102 contacts the first sealing plate 101. At this point, parts of the side and bottom surfaces of the bag material are sequentially bonded under high temperature. Furthermore, the thickness of the side and bottom surfaces is uniform during bonding, resulting in consistent bonding and a better sealing effect at the junction.

[0054] Then, two cylinders 115 control two sliding plates 106 to move away from each other. The sliding plates 106 drive the second sealing plate 102 away from the first sealing plate 101, and also cause the two first sealing plates 101 to move away from each other. Next, the bag material continues to be conveyed by the conveying mechanism. Before the bonded bottom surface passes through the two rollers 120, the bottom surface is folded in half, so that the bottom surface is folded from the middle and away from the side. Then the bag material passes through the two rollers 120 (in the subsequent continuous production process, the bottom surface will gradually fold in half when it is close to the rollers 120, without the need for external force outside the rollers 120). When the folded bottom surface passes through the second sealing mechanism 121, the two sides of the stand-up pouch that are not fully bonded in the first direction and the part of the bottom surface that extends along the third direction at the side bonding position are also bonded together. Then, the bag material continues to be conveyed to the next process by the conveying mechanism.

[0055] A stand-up pouch manufacturing process includes the following steps:

[0056] S1, firstly, the bag material on the machine body 100 is folded in half by the folding mechanism, so that the bottom surface of the bag material is angled, and the folded bag material is passed through the adjustment structure; after the expansion of multiple turntables 103, the angle on the bottom surface gradually increases, and finally approaches a flat angle.

[0057] S2, the first sealing plate 101 is controlled by the drive component to first contact the two sides of the bag material and make the contact parts of the bag material bonded; the side of the bag material with the increased bottom angle comes between the two first sealing plates 101 under the action of the conveying mechanism, and the bottom comes between the second sealing plate 102 and the first sealing plate 101. The cylinder 115 is started to control the slide plate 106 to approach the bag material, and the two first sealing plates 101 first contact the bag material to seal the side part of the bag material.

[0058] S3, the second sealing plate 102 is controlled by the drive component to continue to move closer to the two first sealing plates 101, and the bag material that is clamped and squeezed between the second sealing plate 102 and the first sealing plate 101 is bonded; after contacting the bag material, the first sealing plate 101 no longer slides along the second direction and the third direction, and the slide plate 106 continues to move closer to the bag material, so that the second sealing plate 102 moves closer to the first sealing plate 101, and the second sealing plate 102 and the first sealing plate 101 seal the bottom surface of the bag material.

[0059] S4, using the second sealing mechanism 121 to finally seal the two sides of the stand-up pouch arranged in the first direction; thus forming the stand-up pouch into a container with an opening and capable of standing upright.
