[0002] Embodiments of this disclosure relate to a molding component and a filling device. Background Technology

[0003] In food packaging technology, especially for liquid foods, filling equipment is typically used to produce the packaging. For example, a packaging sleeve with openings at both ends is fed into the filling equipment, which seals one opening and fills the liquid food through the other opening. After filling is complete, the other opening is sealed again, ultimately forming the finished package containing the food. Summary of the Invention

[0004] This disclosure provides a molding component and a filling device.

[0005] At least one embodiment of this disclosure provides a molding assembly, including: a crossbeam extending along a first direction; a plurality of molding arm assemblies disposed on the crossbeam along the first direction, each molding arm assembly including two molding arms disposed opposite to each other along the first direction and drivable to move closer to or further away from each other; and a plurality of first positioning block assemblies mounted on the crossbeam and corresponding one-to-one with the plurality of molding arm assemblies, each first positioning block assembly including two first positioning blocks respectively abutting on both sides of the molding arm assembly along the first direction, the two first positioning blocks between two adjacent molding arm assemblies overlapping in a second direction, the second direction being perpendicular to the first direction.

[0006] For example, in a molding assembly provided in one embodiment of this disclosure, the overlapping area of ​​the two first positioning blocks between two adjacent molding arm groups in a second direction is greater than or equal to half the area of ​​one of the opposing sidewalls of the two first positioning blocks.

[0007] For example, in a molding assembly provided in one embodiment of this disclosure, the crossbeam includes a first surface, the plurality of first positioning blocks are disposed on the first surface, the first positioning block includes a first guide protrusion, the first surface includes a first guide groove, the first guide groove extends along the first direction, and the first guide protrusion is disposed in the first guide groove so that the first positioning block is movable relative to the crossbeam along the first guide groove.

[0008] For example, in a molding component provided in one embodiment of this disclosure, the first surface includes a plurality of first guide grooves, and a first guide protrusion is disposed corresponding to a first guide groove.

[0009] For example, in a molding assembly provided in one embodiment of this disclosure, the plurality of first guide grooves are located on both sides of the first surface along the second direction, and the plurality of first guide grooves located on the same side of the first surface are equally spaced, and the second direction is parallel to the first surface.

[0010] For example, in a molding assembly provided in one embodiment of this disclosure, the first positioning block includes a first mounting hole to allow a fastener to pass through the first mounting hole and fix the first positioning block to the crossbeam, wherein the dimension of the first mounting hole along the first direction is greater than the dimension of the first mounting hole along the second direction.

[0011] For example, in a molding assembly provided in an embodiment of this disclosure, the crossbeam includes a first surface and a second surface disposed opposite to the first surface, the plurality of first positioning block groups are disposed on the first surface, and the molding assembly further includes a plurality of second positioning block groups disposed on the second surface. The plurality of second positioning block groups are disposed one-to-one with the plurality of molding arm groups. Each second positioning block group includes two second positioning blocks respectively abutting on both sides of the molding arm group along the first direction, and the two second positioning blocks between two adjacent molding arm groups are overlapped in the second direction.

[0012] For example, in a molding assembly provided in one embodiment of this disclosure, the orthographic projections of the first positioning block group and the second positioning block group, which are disposed corresponding to the same molding arm group, overlap on the first surface.

[0013] For example, in a molding assembly provided in one embodiment of this disclosure, the two molding arms of the molding arm assembly are rotatably disposed on the crossbeam about their respective axes of rotation so that the two molding arms move closer to or further away from each other.

[0014] For example, in a molding assembly provided in one embodiment of this disclosure, the molding arm penetrates the crossbeam along a third direction. The molding arm includes a main body, a finger-shaped portion disposed at one end of the main body, and a spherical portion disposed at the other end of the main body. The third direction is perpendicular to both the first direction and the second direction. A first positioning block group is respectively abuttingly disposed on both sides of the molding arm group along the first direction, so that there is a first distance between the finger-shaped portions of the two molding arms of the molding arm group. A second positioning block group is respectively abuttingly disposed on both sides of the two molding arms of the molding arm group along the first direction, so that there is a second distance between the finger-shaped portions of the two molding arms of the molding arm group. The first distance is not equal to the second distance.

[0015] For example, in one embodiment of this disclosure, the molding assembly further includes: a plurality of cams disposed on one side of the crossbeam along the second direction, corresponding one-to-one with the plurality of molding arm groups. Each cam includes two convex surfaces disposed opposite each other along the first direction. The crossbeam is rotatable about the first direction so that the spherical portions of the two molding arms of the molding arm group move along the two convex surfaces. The main body rotates about its axis under the drive of the spherical portions so that the finger-like portions of the two molding arms of the molding arm group move closer to or further away from each other.

[0016] At least one embodiment of this disclosure provides a filling apparatus including any of the above-described molding components.

[0018] The molding assembly provided in this embodiment can reduce the space occupied by the two first positioning blocks between two adjacent molding arm groups in the first direction. Thus, more molding arm groups can be set in the first direction to improve the production efficiency of the molding assembly, or the space occupied by the molding assembly can be reduced in the first direction to save space.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0034] Unless otherwise defined, the technical or scientific terms used in this disclosure shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as “comprising” or “including” mean that an element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0035] Unless otherwise defined, the characteristics such as "parallel," "perpendicular," and "identical" used in the embodiments of this disclosure include strictly defined cases of "parallel," "perpendicular," and "identical," as well as cases involving a certain margin of error, such as "approximately parallel," "approximately perpendicular," and "approximately identical." For example, the aforementioned "approximately" may indicate that the difference between the compared objects is within 10% or 5% of the average value of the compared objects. Unless otherwise specified in the following embodiments of this disclosure, the quantity of a component or element is implied to mean that the component or element may be one or more, or can be understood as at least one. "At least one" refers to one or more, and "more" refers to at least two.

[0036] Figure 1 is a cross-sectional schematic diagram of a molding component. As shown in Figure 1, multiple molding units 02 are provided on the molding beam 01. The molding units 02 can be used for product molding. Positioning blocks 03 are provided between the molding units 02 to position the molding units 02 and form products of specific shapes. However, the positioning blocks 02 between the molding units are spaced apart, occupying a large space and hindering the improvement of the molding component's efficiency.

[0037] This disclosure provides a molding assembly and a filling device. The molding assembly includes a crossbeam, multiple molding arm assemblies, and multiple first positioning block assemblies. The crossbeam extends along a first direction, and the multiple molding arm assemblies are disposed on the crossbeam along the first direction. Each molding arm assembly includes two molding arms that are disposed opposite to each other along the first direction and can be driven to move closer to or further away from each other. The multiple first positioning block assemblies are mounted on the crossbeam and are disposed one-to-one with the multiple molding arm assemblies. Each first positioning block assembly includes two first positioning blocks that are respectively abutting on both sides of the molding arm assembly along the first direction. The two first positioning blocks between two adjacent molding arm assemblies are overlapped in a second direction, which is perpendicular to the first direction.

[0038] In the molding assembly provided in the embodiments of this disclosure, by having two first positioning blocks between two adjacent molding arm groups overlap in the second direction, the space occupied by the two first positioning blocks in the first direction can be reduced. Thus, more molding arm groups can be set in the first direction to improve the production efficiency of the molding assembly, or the space occupied by the molding assembly can be reduced in the first direction to save space.

[0039] The molding components and filling equipment provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0040] This disclosure provides a molding assembly. Figure 2 is a structural schematic diagram of a molding assembly provided in this disclosure; Figure 3 is a partial structural schematic diagram of the molding assembly shown in Figure 2. As shown in Figures 2 and 3, the molding assembly 100 includes a crossbeam 110, multiple molding arm assemblies 120, and multiple first positioning block assemblies 130. The crossbeam 110 extends along a first direction X, and the multiple molding arm assemblies 120 are disposed on the crossbeam 110 along the first direction X. Each molding arm assembly 120 includes two molding arms 121 that are disposed opposite to each other along the first direction X and can be driven to move closer to or further away from each other. The multiple first positioning block assemblies 130 are mounted on the crossbeam 110, and the multiple first positioning block assemblies 130 are disposed one-to-one with the multiple molding arm assemblies 120. Each first positioning block assembly 130 includes two first positioning blocks 131 that are respectively abutting on both sides of the molding arm assembly 120 along the first direction X. The two first positioning blocks 131 between two adjacent molding arm assemblies 120 are overlapped in a second direction Y, which is perpendicular to the first direction X.

[0041] The figure schematically shows that eight first positioning block groups 130 are arranged in a one-to-one correspondence with eight forming arm groups 120, and one forming arm group 120 is arranged in a corresponding manner with one first positioning block group 130. This embodiment of the present disclosure does not limit the number of first positioning block groups and forming arm groups; the number of first positioning block groups and forming arm groups can be designed according to actual needs.

[0042] It should be noted that, in this disclosure, two adjacent molding arm groups refer to two molding arm groups without a molding arm group between them. However, structures other than molding arm groups may be provided between the two adjacent molding arm groups, such as positioning blocks. In this disclosure, two first positioning blocks overlapping in the second direction means that the orthographic projections of the two first positioning blocks on a plane perpendicular to the second direction overlap.

[0043] In the molding assembly provided in this embodiment, by having two first positioning blocks between two adjacent molding arm groups overlap in the second direction, the space occupied by the two first positioning blocks in the first direction can be reduced, and the size occupied by the two first positioning blocks in the first direction is less than the sum of the sizes of the two first positioning blocks in the first direction. Therefore, more molding arm groups can be provided in the first direction to improve the production efficiency of the molding assembly, or the space occupied by the molding assembly can be reduced in the first direction, saving space.

[0044] For example, as shown in Figure 3, the dimensions of the two first positioning blocks 131 in the first direction X are both L1. By making the two first positioning blocks 131 between two adjacent forming arm groups 120 overlap in the second direction Y, the dimensions occupied by the two first positioning blocks 131 in the first direction X are L0 < 2L1.

[0045] In some examples, as shown in Figure 3, the overlapping area of ​​the two first positioning blocks 131 between two adjacent forming arm assemblies 120 in the second direction Y is greater than or equal to half the area of ​​one of the opposing sidewalls 1311 of the two first positioning blocks 131. This allows the two first positioning blocks 131 to have a larger overlapping area in the second direction Y, resulting in a smaller size occupied by the two first positioning blocks 131 in the first direction X.

[0046] For example, by making the two first positioning blocks have a larger overlapping area in the second direction, the size L0 ≤ L1 occupied by the two first positioning blocks in the first direction.

[0047] For example, the overlapping area of ​​the two first positioning blocks between two adjacent forming arm assemblies in the second direction is greater than or equal to four-fifths of the area of ​​one of the opposing sidewalls of the two first positioning blocks.

[0048] For example, as shown in Figure 3, the crossbeam 110 includes a first surface S1, a plurality of first positioning block groups 130 are disposed on the first surface S1, and the second direction Y is parallel to the first surface S1.

[0049] For example, as shown in Figure 3, the dimension of the first positioning block 131 in the second direction Y is smaller than the dimension of the crossbeam 110 in the second direction Y. For example, the dimension of the first positioning block 131 in the second direction Y is less than or equal to half the dimension of the crossbeam 110 in the second direction Y.

[0050] Figure 4 is a partial structural schematic diagram of the crossbeam shown in Figure 2; Figure 5 is a cross-sectional schematic diagram of the molding assembly shown in Figure 2 along a direction perpendicular to the first direction. As shown in Figures 4 and 5, the crossbeam 110 includes a first surface S1, and a plurality of first positioning block groups 130 are disposed on the first surface S1. The first positioning block 131 includes a first guide protrusion 131a, and the first surface S1 includes a first guide groove 111. The first guide groove 111 extends along the first direction X, and the first guide protrusion 131a is disposed within the first guide groove 111 so that the first positioning block 131 is movable relative to the crossbeam 110 along the first guide groove 111. Through the cooperation of the first guide protrusion 131a and the first guide groove 111, the first positioning block 131 can be moved along the first guide groove 111. For example, the position of the first positioning block 131 can be adjusted so that the molding arm 121 of the molding arm group 120 is confined to a set position.

[0051] In some examples, as shown in Figures 4 and 5, the first surface S1 includes a plurality of first guide grooves 111, and a first guide protrusion 131a is correspondingly provided with a first guide groove 111. For example, by having a first guide protrusion 131a corresponding with a first guide groove 111, it is convenient to install the first positioning block 131 and avoid misinstallation, multiple installations, or omissions of the first positioning block 131.

[0052] In some examples, as shown in Figures 4 and 5, multiple first guide grooves 111 are located on both sides of the first surface S1 along the second direction Y, and the multiple first guide grooves 111 on the same side of the first surface S1 are equally spaced. This not only facilitates the structural design of the molding assembly 100, but also ensures that the spacing of the first positioning blocks 131 on the same side of the first surface S1 is equal or approximately equal, facilitating installation and use and preventing misalignment of the first positioning blocks 131.

[0053] In some examples, as shown in Figure 5, a direction mark is provided on the first positioning block 131. This direction mark facilitates the installation, identification, and position adjustment of the first positioning block. For example, the direction mark can be an arrow. For instance, the arrow points to the forming arm held by the first positioning block.

[0054] Figure 6 is a cross-sectional schematic diagram of the molding assembly shown in Figure 2 along a path parallel to the first surface. As shown in Figures 5 and 6, the first positioning block 131 includes a first mounting hole 131b to allow a fastener 160 to pass through the first mounting hole 131b and fix the first positioning block 131 to the crossbeam 110. The dimension of the first mounting hole 131b along the first direction X is larger than the dimension of the first mounting hole 131b along the second direction Y. By providing the first mounting hole 131b on the first positioning block 131, not only can the first positioning block 131 be fixed, but it can also be fixed at different positions along the first direction X on the crossbeam 110.

[0055] Figure 7 is a partial structural schematic diagram of the molding assembly shown in Figure 2 from another perspective; Figure 8 is a partial structural schematic diagram of the crossbeam shown in Figure 2 from another perspective. As shown in Figures 2, 7, and 8, the molding assembly 100 also includes a plurality of second positioning block groups 140. The crossbeam 110 also includes a second surface S2 disposed opposite to the first surface S1. A plurality of first positioning block groups 130 are disposed on the first surface S1, and a plurality of second positioning block groups 140 are disposed on the second surface S2. The plurality of second positioning block groups 140 are disposed one-to-one with a plurality of molding arm groups 120. Each second positioning block group 140 includes two second positioning blocks 141 respectively abutting on both sides of the molding arm group 120 along the first direction X. The two second positioning blocks 141 between two adjacent molding arm groups 120 overlap in the second direction Y, which is parallel to the first surface S1. The overlap of two second positioning blocks 141 in the second direction Y means that the orthographic projections of the two second positioning blocks 141 on the plane perpendicular to the second direction Y overlap.

[0056] Figure 2 schematically illustrates that the molding assembly 100 includes eight molding arm groups 120, eight first positioning block groups 130, and eight second positioning block groups 140. Each molding arm group 120 is correspondingly arranged with one first positioning block group 130 and one second positioning block group 140. This embodiment of the present disclosure does not limit the number of molding arm groups 120, first positioning block groups 130, and second positioning block groups 140; the number can be designed according to actual needs.

[0057] It should be noted that Figure 8 schematically shows that the second surface S2 is discontinuous. For example, the second surface can also be continuous, as can be seen with reference to the first surface S1, and this disclosure does not limit it in this way.

[0058] In the molding assembly provided in this embodiment, a first positioning block group can limit the molding arm group to a first extreme position, and a second positioning block group can limit the molding arm group to a second extreme position. Thus, the molding arm group can have two different extreme positions. For example, this molding arm group can be used to mold or pre-form a product.

[0059] By having the two second positioning blocks between two adjacent forming arm assemblies overlap in the second direction, the space occupied by the two second positioning blocks in the first direction can be reduced, and the size occupied by the two second positioning blocks in the first direction is less than the sum of their sizes in the first direction. Therefore, more forming arm assemblies can be set in the first direction to improve the production efficiency of the forming assembly, or the space occupied by the forming assembly can be reduced in the first direction, saving space.

[0060] In some examples, as shown in Figure 7, the overlapping area of ​​the two second positioning blocks 141 between two adjacent forming arm assemblies 120 in the second direction Y is greater than or equal to half the area of ​​one of the opposing sidewalls of the two second positioning blocks 141. This allows the two second positioning blocks 141 to have a larger overlapping area in the second direction Y, resulting in a smaller size occupied by the two second positioning blocks 141 in the first direction X.

[0061] For example, the overlapping area of ​​the two second positioning blocks between two adjacent forming arm assemblies in the second direction is greater than or equal to four-fifths of the area of ​​one of the opposing sidewalls of the two second positioning blocks.

[0062] For example, as shown in Figure 7, the dimension of the first positioning block 131 in the second direction Y is smaller than the dimension of the crossbeam 110 in the second direction Y. For example, the dimension of the first positioning block 131 in the second direction Y is less than or equal to half the dimension of the crossbeam 110 in the second direction Y.

[0063] Figure 9 is a cross-sectional schematic diagram of the molding assembly shown in Figure 2 along a direction perpendicular to the first direction. As shown in Figures 8 and 9, the second positioning block 141 includes a second guide protrusion 141a, and the second surface S2 includes a second guide groove 112. The second guide groove 112 extends along the first direction X, and the second guide protrusion 141a is disposed within the second guide groove 112 to allow the second positioning block 141 to move relative to the crossbeam 110 along the second guide groove 112. Through the cooperation of the second guide protrusion 141a and the second guide groove 112, the second positioning block 141 can move along the second guide groove 112. For example, the position of the second positioning block 141 can be adjusted so that the molding arm 121 of the molding arm assembly 120 is confined to a set position.

[0064] In some examples, as shown in Figure 8, the second surface S2 includes a plurality of second guide grooves 112, and a second guide protrusion 141a is correspondingly provided with a second guide groove 112. For example, by having a second guide protrusion 141a corresponding with a second guide groove 112, it is convenient to install the second positioning block 141 and avoid misinstallation, multiple installations, or omissions of the second positioning block 141.

[0065] In some examples, as shown in Figure 8, multiple second guide grooves 112 are located on both sides of the second surface S2 along the second direction Y, and the multiple second guide grooves 112 on the same side of the second surface S2 are equally spaced. This not only facilitates the structural design of the molding assembly 100, but also ensures that the spacing of the second positioning blocks 141 on the same side of the second surface S2 is equal or approximately equal, facilitating installation and use and preventing misalignment of the second positioning blocks 141.

[0066] Figure 10 is a cross-sectional schematic diagram of the molding assembly shown in Figure 2 along a direction perpendicular to the second direction. As shown in Figure 10, the second positioning block 141 includes a second mounting hole 141b to allow a fastener 160 to pass through the second mounting hole 141b and fix the second positioning block 141 to the crossbeam 110. The dimension of the second mounting hole 141b along the first direction X is larger than the dimension of the second mounting hole 141b along the second direction Y. By providing the second mounting hole 141b on the second positioning block 141, not only can the second positioning block 141 be fixed, but it can also be fixed at different positions along the first direction X of the crossbeam 110.

[0067] In some examples, as shown in Figure 10, the second positioning block 141 is provided with a direction mark. This direction mark facilitates the installation, identification, and position adjustment of the second positioning block. For example, the direction mark can be an arrow. For instance, the arrow points to the forming arm held by the second positioning block.

[0068] In some examples, as shown in Figures 3 and 7, the orthographic projections of the first positioning block group 130 and the second positioning block group 140, which are corresponding to the same forming arm group 120, overlap on the first surface S1. This minimizes the space occupied by the first positioning block group 130 and the second positioning block group 140 on the crossbeam 110 in the first direction X. Consequently, more forming arm groups 120 can be provided in the first direction X to improve the production efficiency of the forming assembly 100, or the space occupied by the forming assembly 100 in the first direction X can be reduced, saving space.

[0069] Figure 11 is a cross-sectional schematic diagram of the molding assembly of Figure 2 along a direction perpendicular to the second direction. As shown in Figure 11, the two molding arms 121 of the molding arm assembly 120 are rotatably mounted on the crossbeam 110 about their respective axes of rotation 161, so that the two molding arms 121 move closer to or further away from each other. For example, the axes of rotation 161 of the molding arms 121 can be parallel to the second direction Y. The embodiments of this disclosure do not limit the way in which the molding arms 121 move closer to or further away from each other; rotation, movement, or other methods can be used to achieve this.

[0070] In some examples, as shown in Figure 11, the forming arm 121 extends through the crossbeam 110 along a third direction Z. The forming arm 121 includes a main body 121a, a finger-shaped portion 121b, and a spherical portion 121c. The finger-shaped portion 121b is disposed at one end of the main body 121a, and the spherical portion 121c is disposed at the other end of the main body 121a. The third direction Z is perpendicular to both the first direction X and the second direction Y. For example, the main body 121a is rotatably fixed to the crossbeam 110. For example, the finger-shaped portion 121b can contact the product to form or preform it. For example, the spherical portion 121c can move along the cam 150 described later to make the forming arm 121 rotatable.

[0071] As shown in Figure 11, the first positioning block group 130 is respectively abutting on both sides of the molding arm group 120 along the first direction X, so that there is a first distance D1 between the finger-shaped portions 121b of the two molding arms 121 of the molding arm group 120. Figure 12 is a schematic diagram of the structure of the molding arm of the molding assembly in Figure 2 abutting with the second positioning block. As shown in Figure 12, the second positioning block group 140 is respectively abutting on both sides of the two molding arms 121 of the molding arm group 120 along the first direction X, so that there is a second distance D2 between the finger-shaped portions 121b of the two molding arms 121 of the molding arm group 120, where the first distance D1 is not equal to the second distance D2. Thus, the two finger-shaped portions 121b of the molding arm group 120 can have two states for molding or pre-molding the product. For example, when the molding arm group 120 is in the first extreme position, there is a first distance D1 between the finger-shaped portions 121b. For example, when the molding arm group 120 is in the second extreme position, there is a second distance D2 between the finger-shaped portions 121b.

[0072] For example, as shown in Figures 11 and 12, the first distance D1 is greater than the second distance D2. For example, at the first distance, the product can be transferred between the two fingers of the forming arm assembly. For example, at the second distance, the product located between the two fingers can be formed or pre-formed.

[0073] In some examples, as shown in Figures 2, 11, and 12, the molding assembly 100 also includes a plurality of cams 150. The plurality of cams 150 are disposed on one side of the crossbeam 110 along the second direction Y, and are corresponding one-to-one with a plurality of molding arm assemblies 120. Figure 2 schematically shows that the molding assembly 100 includes eight molding arm assemblies 120 and eight cams 150, with one molding arm assembly 120 corresponding to one cam 150. The embodiments of this disclosure do not limit the number of molding arm assemblies 120 and cams 150; the number can be designed according to actual needs.

[0074] In some examples, as shown in Figures 11 and 12, each cam 150 includes two convex surfaces 151 arranged opposite each other along a first direction X. The crossbeam 110 is rotatable about the first direction X so that the spherical portions 121c of the two forming arms 121 of the forming arm assembly 120 move along the two convex surfaces 151. The main body 121a rotates about its axis 161 under the drive of the spherical portions 121c so that the finger portions 121b of the two forming arms 121 of the forming arm assembly 120 move closer to or further away from each other. By moving the spherical portions 121c on the convex surfaces 151 of the cam 150 to drive the main body 121a to rotate, the finger portions 121b move closer to or further away from each other. This structural design makes the transmission efficiency between the structures in the forming assembly 100 higher and the cooperation more reliable, making the movement of the finger portions 121b closer to or further away from each other more stable, and resulting in a higher yield of the formed product.

[0075] In some examples, as shown in Figure 2, the crossbeam 110 can rotate under the action of the drive belt 162. The manner in which the crossbeam 110 is driven to rotate is not limited in the embodiments of this disclosure.

[0076] This disclosure also provides a filling apparatus. The filling apparatus includes any of the above-described molding components. Therefore, the filling apparatus can possess the beneficial technical effects corresponding to the beneficial technical effects of the molding component, which will not be elaborated further here.

As shown in Figure 13, the filling device 200 includes a forming assembly 100, a rotating device 210, and a sealing device. The rotating device 210 includes a plurality of forming rods 211 to allow a packaging sleeve 001 to be fitted onto the forming rods 211. The rotating device 210 is configured to drive the forming rods 211 and the packaging sleeve 001 to rotate. The packaging sleeve 001 includes two end openings. The forming assembly 100 is configured to pre-fold one end opening of the packaging sleeve 001 using the two forming arms 121 of the forming arm assembly 120. The sealing device is configured to seal the pre-folded end opening, thereby achieving a seal on the end opening.

[0078] In some examples, as shown in Figure 13, the filling equipment 200 also includes an extraction and unfolding device 220 and a transfer device 230. For example, the extraction and unfolding device 220 unfolds a plurality of flattened, folded packaging sleeves 001 into an upright packaging shell, and the transfer device 230 transfers them to the rotating device 210.
