Description

Technical Field

[0001] This utility model relates to the field of automated packaging technology, and in particular to a paper bag packaging device. Background Technology

[0002] Currently, food packaging abroad generally uses various paper packaging containers such as paper boxes, paper bags, paper tubes, and paper cans. Among these, paper bags are the most widely used and account for the largest proportion. The current international trend in paper product development is towards multifunctional packaging products, such as those with moisture-proof, freshness-preserving, heat-insulating, sterilizing, and anti-corrosion properties, to better protect and preserve food.

[0003] Compared to the international market, my country's paper packaging industry is still somewhat lagging behind. However, with closer exchanges between domestic and international markets, paper bags will account for an increasingly larger share of my country's food packaging industry. After production, paper bags are typically stacked and shipped out after the bottom is folded to fit one side. However, manual packaging of food is inefficient, requires highly skilled workers, and cannot guarantee hygiene and safety. Current paper bag packaging mechanisms generally use compressed air pulses to blow air into the bag during opening, or insert the bag into mechanical moving parts to open it. However, this blowing force not only affects the suction cups on the outside of the bag, causing it to fall off, but also occupies space at the top of the bag, severely hindering the placement of items on top.

[0004] In view of this, it is necessary to design a paper bag packaging equipment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a paper bag packaging equipment that can quickly and orderly complete the opening and filling of paper bags while ensuring the integrity of the bag body.

[0006] To achieve the above-mentioned objectives, this utility model provides a paper bag packaging device, comprising:

[0007] A support frame, wherein a paper bag compartment for storing paper bags is provided on the support frame;

[0008] A rotating adsorption mechanism is installed on the bracket to pick up paper bags in the paper bag compartment and rotate them, so that the paper bags are adjusted from a horizontal state to a vertical state with the opening facing upwards, while the bottom surface of the paper bags forms an angle with the vertical direction.

[0009] The mobile adsorption mechanism is connected to the support via a lateral moving structure and a first longitudinal moving structure, enabling the mobile adsorption mechanism to move both laterally and longitudinally.

[0010] A fixed adsorption mechanism is provided corresponding to the movable adsorption mechanism. The fixed adsorption mechanism is connected to the support through a second longitudinal moving structure, so that the fixed adsorption mechanism can move longitudinally.

[0011] The bottom adsorption mechanism is connected to the bracket via a first height adjustment structure;

[0012] When the moving adsorption mechanism picks up the paper bag from the rotating adsorption mechanism and moves it to the opening position, the paper bag unfolds from a folded state to an open state under the combined action of the moving adsorption mechanism, the fixed adsorption mechanism, and the bottom adsorption mechanism; and

[0013] The auxiliary filling structure is used to support the opening of the paper bag and assist in filling.

[0014] As a further improvement of this utility model, the rotating adsorption mechanism adsorbs onto the side of the paper bag body that is covered by the bottom surface, and several adsorption sites of the rotating adsorption mechanism are located on the side of the bag body that is not covered by the bottom surface.

[0015] As a further improvement of this utility model, when the paper bag is in the open position, the movable adsorption mechanism is located on the side of the paper bag body not covered by the bottom surface, and the fixed adsorption mechanism is located on the side of the paper bag body covered by the bottom surface.

[0016] As a further improvement of this utility model, the adsorption sites of the moving adsorption mechanism include an adsorption point one corresponding to the adsorption site of the rotating adsorption mechanism and an adsorption point two located at the bottom of the side of the bag.

[0017] As a further improvement of this utility model, the adsorption sites of the fixed adsorption mechanism are arranged to correspond to the adsorption sites of the moving adsorption mechanism.

[0018] As a further improvement of this utility model, the auxiliary loading structure includes a funnel connected to a support via a second height adjustment structure and two swing arms connected to both sides of the funnel via a rotation control structure, so that under the action of the rotation control structure, the two swing arms can switch between a tightened state that facilitates insertion into the bag opening and an unfolded support state that abuts against the side of the bag.

[0019] As a further improvement of this utility model, when the paper bag is in the open position, a support platform for placing materials and a pushing mechanism for pushing materials into the paper bag are also provided above the paper bag.

[0020] As a further improvement of this utility model, the rotating adsorption mechanism includes a suction cup frame connected to the support via a telescopic component and a rotating component, and a first suction cup connected to the suction cup frame via an elastic telescopic structure.

[0021] As a further improvement of this utility model, the angle formed between the bottom surface of the paper bag and the vertical upward direction is greater than or equal to 15°.

[0022] As a further improvement of this utility model, the paper bag compartment is connected to the support through a sliding structure.

[0023] The beneficial effects of this utility model are:

[0024] 1. This utility model, by setting up a rotating adsorption mechanism, can simultaneously pick up paper bags from a horizontal to a vertical position through rotation. During rotation, the torque generated ensures that when the paper bag reaches a vertical position, its bottom surface forms an angle with the vertical plane. This, in conjunction with the subsequent moving adsorption mechanism, fixed adsorption mechanism, and bottom adsorption mechanism, allows for rapid bag unfolding without damage. Furthermore, the moving, fixed, and bottom adsorption mechanisms maintain the bag's position, facilitating filling with an auxiliary filling structure. This ensures rapid filling and maintains bag integrity while preventing damage from falling material. Attached Figure Description

[0055] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0056] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0057] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0058] like Figure 1 and Figure 2 As shown, this utility model provides a paper bag packaging device, including:

[0059] The support 110 is provided with a paper bag compartment 120 for storing paper bags 31;

[0060] A rotating adsorption mechanism 130 is mounted on the bracket 110 and is used to pick up the paper bag 31 in the paper bag compartment 120 and rotate it so that the paper bag 31 is adjusted from a horizontal state to a vertical state with the opening facing upward, while the bottom surface of the paper bag 31 forms an angle with the vertical direction.

[0061] The movable adsorption mechanism 140 is connected to the support 110 through a lateral moving structure and a first longitudinal moving structure, so that the movable adsorption mechanism 140 can move in both the lateral and longitudinal directions.

[0062] A fixed adsorption mechanism 150 is provided corresponding to the movable adsorption mechanism 140. The fixed adsorption mechanism 150 is connected to the support 110 through a second longitudinal moving structure, so that the fixed adsorption mechanism 150 can move longitudinally.

[0063] The bottom surface adsorption mechanism 160 is connected to the bracket 110 through a first height adjustment structure;

[0064] When the moving adsorption mechanism 140 picks up the paper bag 31 from the rotating adsorption mechanism 130 and moves it to the opening position, under the combined action of the moving adsorption mechanism 140, the fixed adsorption mechanism 150, and the bottom adsorption mechanism 160, the paper bag 31 unfolds from a folded state to an open state; and

[0065] The auxiliary filling structure 180 is used to support the opening of the paper bag 31 and assist in filling.

[0066] like Figure 3 As shown, for ease of subsequent description of the bag, the folded paper bag 31 is divided into the back side ( Figure 3 a), front ( Figure 3b) and bottom surface ( Figure 3 c) When folded, the side of the bottom that contacts the side of the paper bag 31 is the back, and the other side is the front.

[0067] For example, such as Figure 4 As shown, the paper bag compartment 120 includes a receiving plate 121, a plurality of limiting blocks 122 disposed on the receiving plate 121, a first limiting plate 123, and a force-bearing part 124 disposed on the first limiting plate 123. The receiving plate 121 is provided with a plurality of through holes 1211, and the inner wall of the through holes 1211 is provided with a first snap-fit ​​position and a second snap-fit ​​position. The bottom of the limiting blocks 122 is provided with snap-fit ​​rods 1221 that pass through the through holes 1211, such that when the snap-fit ​​rods 1221 are snapped into the first snap-fit ​​position, the plurality of limiting blocks 122 and the first limiting plate 123 together form a limiting space. When the snap-fit ​​rods 1221 are snapped into the second snap-fit ​​position, the plurality of limiting blocks 122 and the first limiting plate 123 together form a shape larger than the limiting space, so as to facilitate the placement of the paper bags 31. For example, a third latching position, a fourth latching position, etc. can be provided in the perforation 1211 so that the latching rod 1221 forms a limiting space of different sizes when it is in the corresponding latching position, so as to meet the placement requirements of paper bags 31 of different sizes.

[0068] For example, the shape of the limiting space formed by the plurality of limiting blocks 122 and the first limiting plate 123 is the same as the shape of the paper bag 31 when it is folded. When the paper bag 31 is placed in the paper bag compartment 120, the opening of the paper bag 31 faces the moving adsorption mechanism 140.

[0069] The receiving plate 121 is connected to the support 110 via a sliding structure, allowing the paper bag compartment 120 to slide relative to the support 110 when an external force is applied to the force-bearing part 124. This enables the paper bag compartment 120 to switch between a position convenient for placing the paper bag 31 and a position convenient for the rotating adsorption mechanism 130 to adsorb the paper bag. For example, the sliding structure includes a fixed rod 1252 mounted on the support 110 and a slider 1251 sleeved on the fixed rod 1252. The slider 1251 is fixedly connected to the receiving plate 121.

[0070] Specifically, such as Figure 5As shown, the rotating adsorption mechanism 130 includes a suction cup frame 131 connected to the bracket 110 via a telescopic component and a rotating component, and a first suction cup 132 connected to the suction cup frame 131 via an elastic telescopic structure. For example, the telescopic component is a push-pull cylinder 134, and the rotating component is a swing cylinder 135, allowing the suction cup frame 131 to telescopically move under the action of the push-pull cylinder 134. This allows for adjustment of the suction cup frame 131's position as needed during the picking up and rotating of the paper bag 31. Simultaneously, after adsorbing the paper bag 31, the swing cylinder 135 rotates the suction cup frame 131, causing the paper bag 31 to rotate from a horizontal to a vertical position. The specific rotation speed can be adjusted according to actual conditions, ensuring that when the paper bag 31 rotates to a vertical position, the bottom surface of the paper bag 31 forms a certain angle with the vertical plane. For example, the angle formed by the bottom surface of the paper bag 31 and the vertically upward direction is greater than or equal to 15°. Figure 6 ).

[0071] For example, such as Figure 7 As shown, the elastic telescopic structure includes a fixed part 1331 connected to the suction cup frame 131, a telescopic tube 1332 connected to the fixed part 1331, and a spring 1333 sleeved on the telescopic tube 1332. The first suction cup 132 is connected to the end of the telescopic tube 1332 away from the fixed part 1331, and the two ends of the spring 1333 are respectively connected to the fixed part 1331 and the first suction cup 132. The elastic telescopic structure can compensate for the maximum working range of the push-pull cylinder 134 to meet the picking needs of paper bags 31 located at different heights in the paper bag bin 120. That is, during the production process, the maximum working height of the push-pull cylinder 134 is to move the first suction cup 132 to contact the bottom surface of the paper bag bin 120. When the rotary adsorption mechanism 130 is in the picking position, the push-pull cylinder 134 controls the suction cup frame 131 to extend. When there are many paper bags 31 in the paper bag bin 120, although the first suction cup 132 contacts the paper bags 31, the push-pull cylinder 134 can still handle them. As cylinder 134 continues to descend before reaching its maximum working position, and the first suction cup 132 cannot descend further due to contact with the paper bag 31, spring 1333 and telescopic tube 1332 retract to compensate for the maximum working range of the push-pull cylinder 134. As production progresses, the height of the paper bag stack in the paper bag bin 120 gradually decreases, and the retraction length of spring 1333 and telescopic tube 1332 also decreases accordingly. Thus, under the action of the elastic telescopic structure, the rotary adsorption mechanism 130 can accurately adsorb each paper bag 31 in the paper bag bin 120.

[0072] Specifically, when the paper bag 31 is placed in the paper bag compartment 120, its back side faces upwards, meaning the rotary adsorption mechanism 130 adsorbs onto the back side of the paper bag 31. Several adsorption points of the rotary adsorption mechanism 130 are located on the portion of the back side of the paper bag 31 not covered by the bottom surface. This allows the rotational torque to be used to rotate the paper bag 31 to a vertical position, where the bottom surface of the paper bag 31 forms a certain angle with the vertical direction. For example, the lower part of the back side of the paper bag 31 is covered by the bottom surface; the rotary adsorption mechanism 130 has four adsorption points, located at the upper and middle parts of the paper bag 31 respectively. Figure 8 a).

[0073] Specifically, under the action of the lateral moving structure, the moving adsorption mechanism 140 moves to a position relative to the rotating adsorption mechanism 130 to complete the handover of the paper bag 31. Then, when the moving adsorption mechanism 140 moves to the right to a position relative to the fixed adsorption mechanism 150, the paper bag 31 is in the open position. For example... Figure 2 As shown, when the paper bag 31 is in the open position, the movable adsorption mechanism 140 is located on the front side of the paper bag 31, and the fixed adsorption mechanism 150 is located on the back side of the paper bag 31.

[0074] Because the paper bag 31 is relatively fragile, to avoid the paper bag 31 slipping or even breaking due to inconsistent adsorption positions when it is transferred between the rotary adsorption mechanism 130 and the moving adsorption mechanism 140, the adsorption points of the moving adsorption mechanism 140 are set to include adsorption point one corresponding to the adsorption point of the rotary adsorption mechanism 130 and adsorption point two located at the bottom of the side of the bag. The size and adsorption effect of the suction cup of the moving adsorption mechanism 140 are the same as those of the suction cup of the rotary adsorption mechanism 130. Adsorption point one is located at the top and middle of the paper bag 31, and adsorption point two is located at the bottom of the paper bag 31. Figure 8 b); The adsorption sites of the fixed adsorption mechanism 150 are set to correspond to the adsorption sites of the moving adsorption mechanism 140 ( Figure 9 By setting a second adsorption point on the movable adsorption mechanism 140 for adsorbing the bottom of the paper bag 31, the movable adsorption mechanism 140 can be used to uniformly fix the paper bag 31 as a whole. This allows the bottom surface of the paper bag 31 to rotate to a horizontal position when the bottom adsorption mechanism 160 rises. If the movable adsorption mechanism 140 only has the same first adsorption point as the rotating adsorption mechanism 130, the bottom of the paper bag 31 may be bent or even damaged when the bottom adsorption mechanism 160 rises to adjust its position. This is because the paper bag 31 is relatively fragile and lacks support at the bottom, which may affect the subsequent unfolding of the paper bag 31 or render it unusable. In other words, by setting a second adsorption point, this invention facilitates cooperation with the bottom adsorption mechanism 160, ensuring the integrity of the bag while allowing the bottom surface to rotate to a horizontal position, thus facilitating the subsequent unfolding of the paper bag 31.

[0075] Specifically, the mobile adsorption mechanism 140 includes a first frame and six second suction cups 142 fixed on the first frame; the lateral movement structure is an existing lateral telescopic cylinder 143 or a similar structure that can achieve lateral telescopic movement; the first longitudinal movement structure and the second longitudinal movement structure are existing longitudinal telescopic cylinders or similar structures that can achieve longitudinal telescopic movement; for example, the lateral movement structure is a lateral telescopic cylinder 143, and the first longitudinal movement structure is a first longitudinal telescopic cylinder 144. The lateral telescopic cylinder 143 is fixed on the bracket 110, and the first longitudinal telescopic cylinder 144 is fixed at the output end of the lateral telescopic cylinder 143. The output end of the first longitudinal telescopic cylinder 144 is connected to the first frame, so that the extension and retraction of the lateral telescopic cylinder 143 drives the first longitudinal telescopic cylinder 144 to move laterally, thereby driving the mobile adsorption mechanism 140 to move laterally; the extension and retraction of the first longitudinal telescopic cylinder 144 drives the mobile adsorption mechanism 140 to move longitudinally. Figure 9 ).

[0076] The fixed adsorption mechanism 150 includes a second frame and six third suction cups fixed on the second frame. The second longitudinal movement structure is a second longitudinal telescopic cylinder 151, which is fixed on the bracket 110 and its output end is connected to the second frame, so that the extension and retraction of the second longitudinal telescopic cylinder 151 drives the fixed adsorption mechanism 150 to move longitudinally.

[0077] For example, such as Figure 10 As shown, the first frame includes a vertical frame 1411 and three horizontal frames 1412 arranged vertically at intervals. The horizontal frames 1412 are fixed to the vertical frame 1411 by bolts, and the second suction cup 142 is also fixed to both ends of the horizontal frames 1412 by bolts. When the specifications of the paper bag 31 change, the specifications can be adapted to the paper bag 31 by adjusting the fixing position of the bolts or replacing the specifications of the suction cups. For example, the rotating adsorption mechanism 130 can also use a similar connection method to connect the suction cup frame 131 and the first suction cup 132, so that the paper bag 31 packaging equipment can meet the packaging needs of multiple specifications of paper bags 31.

[0078] For example, the third suction cup is fixed to the second frame by bolts.

[0079] Specifically, the bottom adsorption mechanism 160 includes a support plate 161 and a plurality of fourth suction cups 162 disposed on the support plate 161. The support plate 161 is connected to the bracket 110 via a first height adjustment structure. For example, the first height adjustment structure is a first vertical telescopic cylinder 163. The support plate 161 is disposed at the output end of the first vertical telescopic cylinder 163, so that the extension and retraction of the first vertical telescopic cylinder 163 drives the bottom adsorption mechanism 160 to move up and down. Figure 9 ).

[0080] Specifically, when the paper bag 31 is in the open position, a support platform 171 for placing materials and a pushing mechanism for pushing materials into the paper bag 31 are also provided above the paper bag 31. For example, as shown... Figure 11 As shown, two opposing second limiting plates 1711 are installed on the support platform 171 near the paper bag 31. The two second limiting plates 1711 form a concentration area whose size gradually decreases along the direction close to the paper bag 31. The pushing mechanism includes a fixed block 172 and a push rod 173 that passes through the fixed block 172 and can move relative to the fixed block 172 under the action of external force. A push plate 174 is provided on the end of the push rod 173 near the paper bag 31. Under the action of external force, the push rod 173 moves towards the paper bag 31, so that the material is concentrated in the concentration area and falls into the paper bag 31.

[0081] Specifically, such as Figure 12 As shown, the auxiliary filling structure 180 includes a funnel 181 connected to the support 110 via a second height adjustment structure, and two swing arms 182 connected to both sides of the funnel 181 via a rotation control structure. Under the action of the rotation control structure, the two swing arms 182 can switch between a tightened state that facilitates insertion into the bag opening and an expanded support state that abuts against the side of the bag. For example, the second height adjustment structure is a second vertical telescopic cylinder 183, the output end of which is connected to the funnel 181; the rotation control structure is a rotary joint 184 used to control the rotation angle of the swing arms 182. By setting the auxiliary filling structure 180, material can fall into the paper bag 31 along the funnel 181. During this process, the swing arms 182 can also support the bag opening, thereby reducing the impact of the material on the paper bag 31 and reducing the damage to the material itself caused by this filling method.

[0082] The contact point between the swing arm 182 and the paper bag 31 is located below the funnel 181, and the vertical projection of the two swing arms 182 when they are in a contracted state is smaller than the bottom surface dimension of the funnel 181.

[0083] Initially, the two swing arms 182 are retracted. As the funnel 181 descends, the swing arms 182 extend into the bag opening. Under the action of the rotary joint 184, the two swing arms 182 gradually unfold to form a shape with a vertical projection larger than the bottom size of the funnel 181, so that the funnel 181 can extend into the bag opening. As the funnel 181 continues to descend, the funnel 181 extends into the paper bag 31 through the bag opening. At this time, the rotary joint 184 continues to control the swing arms 182 to unfold. When the funnel 181 descends to the predetermined position, the two swing arms 182 unfold to the bottom side and abut against the central axis position on both sides of the paper bag 31, supporting the opening of the paper bag 31. Thus, the auxiliary filling structure 180 is used to support the opening of the paper bag 31 and assist in filling, so as to reduce the impact of the material on the paper bag 31.

[0084] For example, the rotary adsorption mechanism 130, the moving adsorption mechanism 140, the fixed adsorption mechanism 150, and the bottom adsorption mechanism 160 all adopt vacuum adsorption.

[0085] Specifically, the method of using the paper bag packaging equipment includes the following steps:

[0086] S1. The rotary adsorption mechanism 130 is rotated by the swing cylinder 135 until the first suction cup 132 faces downward. The rotary adsorption mechanism 130 is moved down by the push-pull cylinder 134 to pick up the paper bag 31 in the paper bag compartment 120. Then, the rotary adsorption mechanism 130 is moved up by the push-pull cylinder 134 to move the paper bag 31 to a certain height. Then, the rotary adsorption mechanism 130 is rotated by the swing cylinder 135 to rotate the paper bag 31 from a horizontal state to a vertical state with the opening facing upward. At the same time, the bottom surface of the paper bag 31 forms an angle with the vertical direction.

[0087] S2. The moving adsorption mechanism 140 is moved to a position opposite to the rotating adsorption mechanism 130 by the horizontal telescopic cylinder 143. After the moving adsorption mechanism 140 adsorbs the front of the paper bag 31, the rotating adsorption mechanism 130 loses its suction. Then, the position of the moving adsorption mechanism 140 is adjusted by the horizontal telescopic cylinder 143 so that the paper bag 31 moves to the opening position.

[0088] S3. The bottom adsorption mechanism 160 is raised by controlling the first vertical telescopic cylinder 163. During the raising process, the bottom adsorption mechanism 160 first contacts and adsorbs one end of the bottom surface of the paper bag 31. Since there is an angle between the bottom surface of the paper bag 31 and the vertical direction, as the bottom adsorption mechanism 160 rises, the bottom surface of the paper bag 31 is gradually rotated to a horizontal state under the force. Finally, the bottom surface of the paper bag 31 is adsorbed and fixed on the bottom adsorption mechanism 160. Figure 13 );

[0089] S4. The fixed adsorption mechanism 150 is moved longitudinally to adsorb onto the back of the paper bag 31 by the second longitudinal telescopic cylinder 151. Then, the moving adsorption mechanism 140 and the fixed adsorption mechanism 150 are moved in opposite directions by the two longitudinal telescopic cylinders, so that the paper bag 31 is unfolded from the folded state to the open state.

[0090] S5. The auxiliary loading structure 180 is controlled by the second vertical telescopic cylinder 183 to extend into the paper bag 31. The bag opening is supported by the swing arm 182, and the pushing mechanism pushes the material so that the material falls into the paper bag 31 in sequence through the concentration area and the funnel 181 for bagging.

[0091] This invention utilizes the rotation of the rotating adsorption mechanism 130 to adjust the paper bag 31 from a horizontal to a vertical position, facilitating the subsequent unfolding of the paper bag 31 by the opposing movements of the moving adsorption mechanism 140 and the fixed adsorption mechanism 150. Furthermore, the rotation generates torque, causing the bottom surface of the paper bag 31 to form an angle with the vertical direction. This, combined with the bottom adsorption mechanism 160, adjusts the state of the bottom surface of the paper bag 31, allowing it to be unfolded only after the bottom surface has been adjusted. This avoids the bottom surface of the paper bag 31 being folded and adhered to the back of the paper bag, which would hinder its unfolding. This opening method is simple, quick, and ensures the integrity of the bag. Simultaneously, the moving adsorption mechanism 140, the fixed adsorption mechanism 150, and the bottom adsorption mechanism 160 maintain the state of the paper bag 31, facilitating subsequent filling.

[0092] Specifically, after the materials are bagged, the paper bag 31 is sent into the sealing device for sealing.

[0093] For example, a push cylinder is also provided on the left side of the bottom adsorption mechanism 160, and an inclined plate 191 that plays a buffering role is connected to the right side of the support plate 161.

[0094] Specifically, such as Figure 14 , Figure 15 , Figure 18 , Figure 21 and 22 As shown, the sealing device includes:

[0095] Frame 210;

[0096] A support member is provided on the frame 210 for placing the paper bag 31;

[0097] The pushing mechanism 220 is connected to the frame 210 through the telescopic adjustment member 223 and the first rotation adjustment member 224. The two pushing mechanisms 220 are respectively set on the front side and the back side of the paper bag 31, so that under the action of the telescopic adjustment member 223 and the first rotation adjustment member 224, the two pushing mechanisms 220 move and drive the upper part of the paper bag 31 from an open state to a narrowed state with the opening gradually decreasing in diameter along the vertical upward direction;

[0098] The two air blowing mechanisms 250 are respectively arranged on both sides of the paper bag 31 to provide an anti-outward force to the sides of the paper bag 31.

[0099] The first crossbar 231 is connected to the frame 210 via the first longitudinal telescopic component 2312, so that the first crossbar 231 can move longitudinally;

[0100] The second crossbar 240 is connected to the frame 210 through the second longitudinal telescopic component 241 and the transverse telescopic component 242, so that the second crossbar 240 can move longitudinally and laterally, and the first crossbar 231 and the second crossbar 240 together serve as a clamping structure for clamping the opening of the paper bag 31.

[0101] The rotating plate 232 is connected to the first crossbar 231 through the second rotating adjustment member 2322, so that under the action of the second rotating adjustment member 2322, the rotating plate 232 can rotate around the first crossbar 231 to drive the top of the paper bag 31 to fold.

[0102] The labeling mechanism is used to attach labels to the paper bag 31 to seal and secure the paper bag 31.

[0103] like Figure 16 As shown, for ease of description of the sealing process of the paper bag 31, when the clamping structure clamps the paper bag 31, the part of the paper bag 31 above the clamping structure is called the folding part 32, and the side of the paper bag 31 covered by the folding part 32 is called the fixed surface 33.

[0104] Specifically, the support is a support platform 211, on which a conveyor belt 212 and a limiting vertical plate 213 are provided; the two limiting vertical plates 213 are respectively provided on both sides of the support platform 211. The limiting vertical plate 213 includes a shrinking section and a parallel section connected to the shrinking section. The shrinking section of the two limiting vertical plates 213 forms a trapezoidal area whose size gradually decreases along the direction close to the pushing mechanism 220. The distance between the two parallel sections is adapted to the width of the paper bag 31.

[0105] After the paper bag 31 is filled with material, the moving adsorption mechanism 140 and the fixed adsorption mechanism 150 lose their suction force. At the same time, the bottom adsorption mechanism 160 descends to its initial height, causing the inclined plate 191 to overlap one end of the support platform 211. Then, the bottom adsorption mechanism 160 is controlled to lose its suction force. Under the action of the push cylinder, the paper bag 31 moves along the inclined plate 191 onto the support platform 211. Figure 26 Since the paper bag 31 has a certain weight at this time, it may become skewed during movement. By setting a trapezoidal area, the orientation of the paper bag 31 can be corrected. Figure 17 This allows the paper bag 31 to move to a predetermined position and be sealed under the action of the conveyor belt 212.

[0106] The height of the limiting vertical plate 213 is set according to the center of gravity height of the paper bag 31 after it is filled with materials, so that the height of the limiting vertical plate 213 is greater than or equal to the center of gravity height of the paper bag 31 after it is filled with materials.

[0107] Specifically, such as Figure 18As shown, the pushing mechanism 220 includes a pushing rod 221 and a push wheel 222 mounted on the pushing rod 221, which can rotate around the pushing rod 221 as an axis. For example, a telescopic adjustment member 223 is fixed to the frame 210, and a first rotation adjustment member 224 is fixed to the output end of the telescopic adjustment member 223. The output end of the first rotation adjustment member 224 is connected to the pushing rod 221, causing the telescopic adjustment member 223 to extend and retract longitudinally, thereby driving the first rotation adjustment member 224 to move longitudinally, and thus driving the pushing mechanism 220 to move longitudinally; the rotation of the first rotation adjustment member 224 drives the pushing mechanism 220 to rotate. Figure 19 As shown, in the initial state, the push rod 221 is in a downward angle towards the paper bag 31. The first rotation adjustment component 224 controls the rotation of the push rod 221, causing the push rod 221 to rotate upward and causing the opening of the paper bag 31 to shrink. When the push rod 221 is rotated to a predetermined position according to the condition of the paper bag 31, the longitudinal telescopic component controls the two push rods 221 to move closer to each other, so that the opening of the paper bag 31 is in a narrowed shape of a predetermined size.

[0108] When the push mechanism 220 is controlled by the first rotary adjustment component 224 to perform the pinching process on the paper bag 31, due to the fragility of the paper bag 31 material, it is necessary to control the rotation speed of the push mechanism 220 to not be too fast, otherwise the paper bag 31 will be damaged.

[0109] Specifically, since paper bags 31 are stacked and stored after production, and there is a centered vertical fold line on the side of paper bags 31, when the top of paper bags 31 is cinched, the side of paper bags 31 may have two general variations: one is the inward cinching of the side required for sealing paper bags 31 ( Figure 20 a) One type is the side-turning that can cause damage to the packaging ( Figure 20 (b) Therefore, by setting two air blowing mechanisms 250 on both sides of the paper bag 31, the present invention can complete the shrunking process of the paper bag 31 through the cooperation of the air blowing mechanism 250 and the pushing mechanism 220, thus avoiding the situation where the side of the paper bag 31 turns outward.

[0110] For example, both air blowing mechanisms 250 are correspondingly mounted on the frame 210 via a third longitudinal telescopic assembly 252. Figure 18 ).

[0111] During the pinching process, the third longitudinal telescopic component 252 extends and drives the center of the air outlet 251 of the air blowing mechanism 250 to align with the vertical fold line on the upper part of the paper bag 31, i.e., the side of the paper bag 31 without material, so as to provide an anti-outward force for the side of the paper bag 31. Figure 20 a) The gas blown out by the blowing mechanism 250 should not be too large, otherwise the weight of the paper bag 31 will be concentrated at the bottom due to the material inside the paper bag 31. Due to the uneven force on the upper and lower parts of the paper bag 31, the upper part of the paper bag 31 will be torn off by the gas blown out by the blowing mechanism 250.

[0112] Since the bag opening needs to be folded over and then secured with a label, the final fixing height of the push roller 222 needs to be controlled to be below the opening of the paper bag 31 to allow for the subsequent folding length. For example, when a subsequent process requires folding the portion of the paper bag 31 at or above the opening, the push roller 222 is ultimately fixed at a distance of 80mm from the opening of the paper bag 31. Figure 19 ).

[0113] Since the narrowing of the paper bag 31 is only an elastic deformation, after the pushing mechanism 220 and the blowing mechanism 250 work together to make the paper bag 31 narrow, the pushing mechanism 220 and the blowing mechanism 250 are kept in their current state to maintain the narrowing deformation of the paper bag 31.

[0114] For example, such as Figure 21 As shown, the first longitudinal telescopic component 2312 is fixed on the frame 210, and the first crossbar 231 is set at the output end of the first longitudinal telescopic component 2312, so that the first longitudinal telescopic component 2312 telescopically drives the first crossbar 231 to move longitudinally.

[0115] The second longitudinal telescopic component 241 is fixed on the frame 210, the transverse telescopic component 242 is disposed at the output end of the second longitudinal telescopic component 241, and the second crossbar 240 is disposed at the output end of the transverse telescopic component 242, so that the extension and retraction of the second longitudinal telescopic component 241 drives the transverse telescopic component 242 to move longitudinally, thereby driving the second crossbar 240 to move longitudinally; the extension and retraction of the transverse telescopic component 242 drives the first crossbar 231 to move laterally.

[0116] Specifically, the second rotating adjustment member 2322 is disposed at the output end of the first longitudinal telescopic component 2312; the rotating plate 232 is sleeved on the first crossbar 231 and can rotate around the first crossbar 231 as an axis. For example, the first crossbar 231 has several annular notches spaced along its axial direction, and several rotating blocks 2311 with diameters smaller than the outer diameter of the first crossbar 231 are correspondingly sleeved at the annular notches. One side of the rotating plate 232 is connected to several rotating blocks 2311, allowing the rotating blocks 2311 to rotate relative to the first crossbar 231. The output end of the second rotating adjustment member 2322 is connected to the rotating plate 232 via a connecting rod 2323, allowing the second rotating adjustment member 2322 to control the connecting rod 2323 to rotate, thereby causing the rotating plate 232 to rotate around the first crossbar 231 as an axis. Figure 22 By making the diameter of the rotating block 2311 smaller than the outer diameter of the first crossbar 231, it is possible to avoid the rotating block 2311 contacting the paper bag 31 when rotating, thus affecting the clamping and fixing effect of the first crossbar 231 and the second crossbar 240 on the paper bag 31.

[0117] For example, the width of the rotating plate 232 is greater than the width of the folding part 32, and the rotating plate 232 is provided with a labeling notch 2321 for easy labeling.

[0118] Specifically, the diameter of the second crossbar 240 is smaller than that of the first crossbar 231, so that the second rotating adjustment member 2322 can control the rotating plate 232 to rotate and drive the folding part 32 to fold so that the folding part 32 finally fits against the fixed surface 33, thus avoiding the second crossbar 240 from hindering the rotation of the rotating plate 232. Meanwhile, since the second crossbar 240 is always clamped to the first crossbar 231 during the folding process of the folding part 32, in order to avoid the presence of the second crossbar 240 affecting the final sealing effect, the diameter of the second crossbar 240 needs to be controlled within a small range. At this time, in order to prevent the second crossbar 240 from bending due to force during the clamping process and to ensure that the second crossbar 240 can maintain a good clamping effect with the first crossbar 231, a support block 261 is also connected to the frame 210 through the fourth longitudinal telescopic component 262. The support block 261 is provided with a center hole with a size slightly larger than that of the second crossbar 240, so that under the action of the transverse telescopic component 242, the end of the first crossbar 231 away from the transverse telescopic component 242 can be inserted into the center hole.

[0119] After the paper bag 31 is closed, the second horizontal bar 240 is inserted into the support block 261 by the extension and retraction control of the horizontal telescopic component 242. Then, the second longitudinal telescopic component 241 and the fourth longitudinal telescopic component 262 extend and retract synchronously to move the second horizontal bar 240 closer to the back of the paper bag 31. At the same time, the first longitudinal telescopic component 2312 moves the first horizontal bar 231 closer to the front of the paper bag 31, so that the first horizontal bar 231 and the second horizontal bar 240 clamp the opening of the paper bag 31. Then, the second rotary adjustment component 2322 controls the rotation of the rotating plate 232, so that the folded part 32 is folded and attached to the fixed surface 33. Figure 23 ).

[0120] For example, such as Figure 24 As shown, the labeling mechanism includes a label adsorption structure 271 connected to the frame 210 via a first telescopic member 2711 and a third rotary adjustment member 2712, and a label separation structure 272 located below the label adsorption structure 271.

[0121] For example, the label adsorption structure 271 is an existing structure that achieves object adsorption through vacuum adsorption. The third rotation adjustment member 2712 is fixed on the frame 210, the first telescopic member 2711 is disposed at the output end of the third rotation adjustment member 2712, and the label adsorption structure 271 is disposed at the output end of the first telescopic member 2711.

[0122] For example, such as Figure 25As shown, the label separation structure 272 includes an input roller 2721 and an output roller 2724 detachably mounted on a frame 210, and a separation component located between the input roller 2721 and the output roller 2724. The separation component includes a platform 2722 and a transverse flattening column 2723 disposed on the platform 2722 near the input roller 2721. The bottom surface of the platform 2722 away from the input roller 2721 is an inclined surface facing downwards towards the input roller 2721. A label roll formed by winding a label strip 2725 is mounted on the input roller 2721. The label strip 2725 includes a base paper and a label on the base paper. The label strip 2725 is output from the input roller 2721, passes over the transverse flattening column 2723, falls onto the platform 2722, and then passes sequentially over the top surface and the inclined surface of the platform 2722 before being wound onto the output roller 2724. Under the action of the input roller 2721 and the output roller 2724, the label strip 2725 moves from the input roller 2721 to the output roller 2724. When the label strip 2725 passes around the transverse flattening post 2723, the transverse flattening post 2723 can provide a frictional force opposite to the direction of label movement. Thus, the setting of the transverse flattening post 2723 can prevent the label strip 2725 between the input roller 2721 and the output roller 2724 from wrinkling.

[0123] When the label strip 2725 moves to the end of the platform 2722 away from the input roller 2721, due to the different toughness of the label and the backing paper, as the backing paper continues to move along the slope toward the output roller 2724, the label gradually separates from the backing paper at the end of the platform 2722. At this time, the first telescopic member 2711 controls the label adsorption structure 271 to move down to adsorb the label. Then, the first telescopic member 2711 contracts to control the label adsorption structure 271 to move up, causing the label to move up. The backing paper continues to move toward the output roller 2724 and wraps around the output roller 2724, thus realizing the separation and picking of the label.

[0124] After the label adsorption structure 271 rises to a predetermined height, the third rotating adjustment member 2712 controls the first telescopic member 2711 to rotate, thereby causing the label adsorption structure 271 to rotate to a horizontal state. Then, the first telescopic member 2711 extends, causing the label adsorption structure 271 to move horizontally through the labeling notch 2321 and adhere the label to the paper bag 31, so that the folded part 32 is fixed on the fixing surface 33 to complete the labeling fixation. For example, 4 / 7 of the label is adhered to the folded part 32, and 3 / 7 of the label is adhered to the fixing surface 33.

[0125] During the labeling process, a labeling support is provided to ensure the label adheres well to the paper bag 31. This support is mounted on a push rod 221 on one side of the fixed surface. For example, a horizontal rod 225 is connected to the end of the push rod 221 away from the first rotating adjustment member 224, and two push wheels 222 are respectively located at both ends of the horizontal rod 225. A support rod 281 is also connected to the middle of the horizontal rod 225 on the side of the paper bag 31 away from the rotating adsorption structure via a second telescopic member. A horizontal cylinder 282 is connected to the end of the support rod 281 away from the second telescopic member. Figure 18 When labeling, the support rod 281 is moved closer to the paper bag 31 by the second telescopic component until the transverse cylinder 282 is located on the front of the paper bag 31 corresponding to the labeling notch 2321, so that the transverse cylinder 282 can be used to support the subsequent labeling and improve the adhesion between the label and the paper bag 31.

[0126] Specifically, the telescopic adjustment component 223, the lateral telescopic assembly 242, the longitudinal telescopic assembly, and the telescopic member are existing structures such as telescopic cylinders that can realize the corresponding adjustment functions described in this utility model; the rotary adjustment component is an existing structure such as a rotary cylinder that can realize the corresponding rotary adjustment functions described in this utility model, and will not be described in detail here.

[0127] Specifically, the frame 210 is also equipped with three sheet metal shell plates 290 located above the paper bag 31 and on one side of the front and back of the paper bag 31, respectively, to meet the requirements of production safety and ventilation and heat dissipation.

[0128] Specifically, the method of using the sealing device includes the following steps:

[0129] S1. The first rotary adjustment component 224 controls the rotation of the push rod 221, causing the two push rods 221 to rotate upward and shrink the opening of the paper bag 31. When the push rod 221 rotates to a predetermined posture, the longitudinal telescopic component controls the two push rods 221 to move closer to each other, so that the opening of the paper bag 31 is in a shrunken shape of a predetermined size. When the rotary adjustment component and the longitudinal telescopic component control the push rod 221 to shrink the opening of the paper bag 31, the third longitudinal telescopic mechanism controls the movement of the air blowing mechanism 250, so that the air outlet 251 of the air blowing mechanism 250 is aligned with the vertical fold line on the upper part of the paper bag 31, i.e., the side of the paper bag 31 without material, to provide an anti-outward force for the side of the paper bag 31.

[0130] S2. Keep the push rod 221 and the air blowing mechanism 250 in their current working state. Control the extension and retraction of the second crossbar 240 by the lateral telescopic component 242 to insert one end of the second crossbar 240 into the support block 261. Then, make the second longitudinal telescopic component 241 and the fourth longitudinal telescopic component 262 extend and retract synchronously to move the second crossbar 240 closer to the back of the paper bag 31. At the same time, the first longitudinal telescopic component 2312 makes the first crossbar 231 closer to the front of the paper bag 31, so that the first crossbar 231 and the second crossbar 240 clamp the opening of the paper bag 31. Then, control the rotation of the rotating plate 232 by the second rotating adjustment component 2322 to make the folded part 32 folded and attached to the fixed surface 33.

[0131] S3. After the label adsorption structure 271 is controlled by the first telescopic member 2711 to adsorb the label from the label separation structure 272, the label adsorption structure 271 is rotated by the third rotary adjustment member 2712 to pass the labeling notch 2321 and adhere it to the paper bag 31, so that the folded part 32 is fixed on the fixed surface 33 to complete the labeling fixation. Before labeling, the support rod 281 is moved closer to the paper bag 31 by the second telescopic member until the transverse cylinder 282 is located on the front of the paper bag 31 corresponding to the labeling notch 2321, so as to use the transverse cylinder 282 to support the subsequent labeling. During the labeling process, the push rod 221 remains in the current working state. As for the air blowing mechanism 250, it can be kept in the current working state or turned off as needed.

[0132] S4. After labeling the paper bag 31, remove the first horizontal bar 231 and the second horizontal bar 240 to seal the paper bag 31. When removing the horizontal bars, control the first horizontal bar 231 to move longitudinally away from the paper bag 31 through the first longitudinal telescopic component 2312, and drive the second horizontal bar 240 to move away from the support block 261 through the telescopic component 242 until the paper bag 31 is removed. Then, control the second horizontal bar 240 to move longitudinally away from the paper bag 31 through the second longitudinal telescopic component 241 to remove the two horizontal bars.

[0133] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
