Description

Technical Field

[0001] This invention relates to the field of heat patch production, specifically to an automatic bagging machine for heat patch production. Background Technology

[0002] Warm patches (also known as heat packs or hot compresses) are external heating products that generate heat through a chemical reaction. They are mainly composed of iron powder, activated carbon, vermiculite, water, salt, and other materials. They release heat through the oxidation reaction of iron and are suitable for keeping warm in winter and relieving muscle and joint pain. The core principle is to use a galvanic cell reaction to accelerate the oxidation of iron powder. The manufacturing process mainly includes the following steps: raw material pretreatment, mixing, packaging, activation treatment, and finished product packaging.

[0003] In the subsequent bagging of finished products, bagging machines are commonly used in daily life. The formed hand warmers are conveyed to one side of the grippers by a conveyor mechanism. Simultaneously, a reciprocating cylinder moves the packaging bag on one side to the hand warmer. A lifting cylinder moves the suction cup downwards, creating negative pressure to suction the top opening of the packaging bag and move it upwards. At this point, the grippers themselves expand to both sides, positioning themselves at the opening of the packaging bag and completing the opening process. The conveyor mechanism then continues to move the hand warmers, transferring the formed hand warmers into the packaging bag, thus completing the packaging process. However, in actual operation... During the process, when the suction cup pulls open the upper layer of the packaging bag, the lower layer of the packaging bag will move upwards due to static electricity. At this time, when the grippers rotate to both sides, it is difficult to open the opening of the packaging bag. As a result, the hand warmer will be outside the packaging bag, affecting the overall packaging effect and stability. At the same time, during the process of conveying the hand warmer through the conveyor mechanism, the friction of the conveyor mechanism will cause the hand warmer to tilt, resulting in the hand warmer not being aligned with the opening of the packaging bag. If the hand warmer is directly put into the bag in this state, the subsequent sealing will cause material to get stuck, resulting in poor sealing, air leakage, and affecting the overall service life.

[0004] In summary, the above structure results in the hand warmer being outside the packaging bag during the actual bagging process, affecting the overall bagging effect and stability. Furthermore, the friction of the conveying mechanism can cause the hand warmer to tilt, which affects its overall service life after bagging. Summary of the Invention

[0005] Based on this, the purpose of this invention is to provide an automatic bagging machine for the production of hand warmers, so as to solve the technical problems that in the actual bagging process, the hand warmers may be outside the packaging bag, affecting the overall bagging effect and stability, and the hand warmers may tilt due to the friction of the conveying mechanism, which affects their overall service life after bagging.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic bagging machine for producing heat patches, comprising a feeding rack and a feeding mechanism, wherein a bagging plate is provided on one side of the feeding mechanism, and a bag-taking component is provided on one side of the bagging plate, a baffle is provided on the bagging plate, a gripper is rotatably provided at one end of the baffle, a guide post is slidably provided on the gripper in the vertical direction, wherein a stop bar is sleeved on the outer wall of the guide post, and an irregularly shaped sliding groove that cooperates with the guide post is provided on the bagging plate at the gripper; The bottom of the gripper is connected to a drive gear, and a driven gear meshes with one side of the drive gear. A shaped cam is connected to the top of the driven gear, and a piston cylinder is provided on one side of the shaped cam. A lower adsorption component that cooperates with the piston cylinder is provided at one end of the gripper on the bagging plate, and an upper adsorption component is slidably provided on the bagging plate at the top of the lower adsorption component.

[0007] By adopting the above technical solution, the guide post and the irregular slid groove cooperate to make the baffle slide down and rotate, and be perpendicular to the side of the bagging plate in a horizontal state. The baffle makes the warm patch flush with the bag opening, which facilitates the subsequent bagging effect and effectively prevents the material from getting stuck. The irregular cam at the top rotates through the meshing of the driven gear. At this time, the irregular cam releases its contact with the abutment plate, so that the lower adsorption component is in an adsorption state on the bottom of the packaging bag, thereby completing the opening of the packaging bag. This can effectively prevent the bottom of the packaging bag from moving upward due to static electricity.

[0008] The present invention is further configured such that the feeding mechanism includes a feeding cylinder, a first electric suction cup, a feeding frame, a feeding belt and a storage rack, wherein a feeding frame is provided on one side of the feeding frame, and a storage rack is provided on the feeding frame. The storage rack itself is L-shaped and an array of feeding belts is provided at the storage rack. A feeding cylinder is provided on the feeding frame, and a first electric suction cup is provided at the output end of the feeding cylinder.

[0009] Preferably, the warming patches conveyed on the feeding rack are stored by the storage rack. Then, with the cooperation of the feeding cylinder and the first electric suction cup, the warming patches are conveyed to one side by the feeding belt. This ensures that the output speed on the front feeding rack is completely synchronized with the speed of the rear bagging machine. The device maintains continuous production through the buffer adjustment of the feeding mechanism, thereby solving the matching problem between the front and rear processes of the production line and improving the stability and efficiency of the subsequent warming patch bagging.

[0010] The present invention is further configured such that the bag-retrieving assembly includes a base plate, a slot, a second electric suction cup, and a collection frame. The top side of the bagging plate is provided with a base plate, and a collection frame is provided on the top of the base plate. The collection frame is also L-shaped. The second electric suction cup is slidably arranged in the vertical direction on the bagging plate, and a slot is provided on the base plate at the location of the second electric suction cup.

[0011] Preferably, the reciprocating cylinder drives the gripping component to move to the bottom plate, and then the gripping component is in the open state. Then the second electric suction cup moves upward so that it contacts the bottom of the packaging bag to complete the adsorption work. Then it slides down by resetting itself so that the packaging bag is pulled out of the slot of the collection frame. Since the collection frame is also L-shaped, the remaining packaging bags can be stored in the collection frame. The above process is repeated until the packaging of the warming patch is completed.

[0012] The present invention is further configured such that a reciprocating cylinder is slidably arranged on one side of the bagging plate, and a gripping component is arranged on one side of the reciprocating cylinder, the gripping component being used for bag picking and conveying at the bag picking component.

[0013] Preferably, the packaging bag is pulled out of the collection box by the second electric suction cup, and the end of the packaging bag is clamped and limited by the gripping component. At the same time, the packaging bag is slid towards the mounting frame by the action of the reciprocating cylinder.

[0014] The present invention is further configured such that a piston assembly is elastically disposed inside the piston cylinder, and an abutment plate that cooperates with the irregular cam is connected to one side of the piston assembly.

[0015] Preferably, under normal conditions, the piston assembly is in a compressed state inside the piston cylinder. When the irregular cam rotates under the action of the driven gear, the irregular cam will release the limit on the abutment plate. At this time, under the reset action of the elastic component, the abutment plate is reset and slid, thereby driving the piston assembly to move inside the piston cylinder, so that the lower adsorption component can adsorb the bottom of the packaging bag.

[0016] The present invention is further configured such that a mounting frame is provided on the top of the bagging plate, and a lifting cylinder is provided on the mounting frame, the lifting cylinder being used to drive the upper adsorption component at the output end to reciprocate in the vertical direction.

[0017] Preferably, the upper adsorption component at the output end is slid up and down within the mounting frame by the action of the lifting cylinder to complete the opening of the packaging bag.

[0018] The present invention is further configured such that a second feeding belt is provided on one side of the bagging plate located on the lower adsorption component, and a first feeding belt is provided on the bagging plate located on the inner side of the enclosure.

[0019] Preferably, after the heat packs are packaged, the second feeding belt will transport them to the next process to prevent them from piling up at the mounting frame. The first feeding belt will also stably transport the heat packs to the grippers to ensure that one end of the heat pack makes full contact with the upper stop bar of the gripper.

[0020] The present invention is further configured such that the bottom of the guide post is provided with an arc-shaped end face, and the contact surface between the arc-shaped end face and the irregular groove is smooth.

[0021] Preferably, the arc-shaped end face helps to prevent the bottom of the guide post from getting stuck with the irregular groove during the rotation of the gripper, and the smooth shape effectively reduces the sliding friction between the two.

[0022] The present invention is further configured such that the corners of the abutment plate are rounded, and the corners are provided with smooth surfaces.

[0023] Preferably, the rounded corners facilitate contact and sliding with the abutment plate during the rotation of the irregularly shaped cam. The smooth surface reduces the friction when the two contacts, improving the overall rotational stability.

[0024] The present invention is further configured such that a limiting mechanism is provided at the connection between the guide post and the gripper, and the limiting mechanism limits the rotation of the guide post in the horizontal direction.

[0025] Preferably, the limiting mechanism is designed to prevent the guide post from rotating during the rotation of the gripper itself, ensuring that after the gripper has rotated, the stop bar and the side of the bagging plate remain perpendicular in a horizontal state.

[0026] In summary, the present invention has the following main beneficial effects: This invention features a feeding mechanism on one side of the feeding rack, with a storage rack on top. The storage rack stores the warming patches being fed from the feeding rack. Then, with the cooperation of a feeding cylinder and a first electric suction cup, the warming patches are uniformly fed to one side via a feeding belt. This ensures that the output speed of the front-end feeding rack is completely synchronized with the speed of the rear-end bagging machine. The device maintains continuous production through the buffer adjustment of the feeding mechanism, thereby solving the matching problem between the front and rear processes of the production line and improving the stability and efficiency of subsequent warming patch bagging. This invention features a rotatable gripper on a bagging plate, with a stop bar positioned on the gripper. When the gripper is tilted inward, the stop bar slides down and rotates through the cooperation of a guide post and a shaped groove, becoming perpendicular to the side of the bagging plate in a horizontal state. At this time, as the heat pack slides to one side through the feeding mechanism, the stop bar ensures that the heat pack is flush with the bag opening, improving the subsequent bagging effect and effectively preventing material jamming. When the gripper resets and the heat pack moves into the bag opening, the stop bar slides upward through the shaped groove. The heat pack moves through the bottom of the stop bar, preventing it from obstructing the heat pack and improving the overall bagging efficiency of the device. This invention features a drive gear at the bottom of the gripper. This drive gear meshes with the driven gear, causing the top-mounted cam to rotate. The cam then disengages from the abutment plate, and the piston assembly, activated by the elastic component, slides back to its original position. The piston assembly draws gas from the piston cylinder, causing the lower adsorption component to adsorb the bottom of the packaging bag. Simultaneously, the upper adsorption component, in conjunction with a lifting cylinder, moves the top of the packaging bag upwards to open it. This completes the opening of the packaging bag. During this process, the lower adsorption component limits the bottom of the packaging bag, effectively preventing the bottom from moving upwards due to static electricity. This ensures the bag fits snugly inside the packaging bag during the filling process, improving overall bagging stability. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of the present invention will now be described.

[0031] Example 1: Please refer to Figures 1-12 An automatic bagging machine for producing heat patches is shown, including a feeding rack 1, a feeding mechanism 2, a bagging plate 3, a bag-taking component 4, a straightening mechanism, and a bag-opening mechanism. The feeding rack 1 conveys the heat patches that have been produced at the front end to the feeding mechanism 2, and the feeding mechanism 2 causes them to slide to one side. The feeding mechanism 2 has a bagging plate 3 on one side and a bag-taking component 4 on the other side. The bagging plate 3 has a baffle 11, and a gripper 12 is rotatably mounted at one end of the baffle 11. In the normal state, the gripper 12 is tilted inward. The heat patch can be conveyed to the gripper 12 by the action of the first feeding belt 10. Since a guide post 16 is slidably mounted vertically on the gripper 12, and a stop bar 18 is fitted on the outer wall of the guide post 16, and a special-shaped groove 17 that cooperates with the guide post 16 is opened on the bagging plate 3 at the gripper 12, when the gripper 12 is in an inclined state, its guide post 16 is at the bottom of the special-shaped groove 17, and the guide post 16 will drive the stop bar 18 to slide down. During this process, the stop bar 18 will block one end of the heat patch. In this state, the stop bar 18 is perpendicular to the side wall of the bagging plate 3. When the heat patch is conveyed by the first feeding belt 10, it is ensured that one end of the heat patch can fully contact the inner wall of the stop bar 18. At this time, the heat patch and the side of the bagging plate 3 are perpendicular in a horizontal state. Furthermore, a reciprocating cylinder 5 is slidably arranged on one side of the bagging plate 3, and a gripping component 14 is arranged on one side of the reciprocating cylinder 5. The gripping component 14 is used for bag picking and conveying at the bag picking component 4. The packaging bag is pulled out from the collection frame 404 by the second electric suction cup 403, and the end of the packaging bag is limited and clamped by the gripping component 14. At the same time, the packaging bag is driven to slide towards the mounting frame 8 by the reciprocating cylinder 5. The top of the bagging plate 3 is provided with the mounting frame 8, and a lifting cylinder 9 is provided on the mounting frame 8. The lifting cylinder 9 is used to drive the upper adsorption component 13 at the output end to slide down to the top of the packaging bag. At this time, the upper adsorption component 13 adsorbs and limits the top of the packaging bag. At the same time, the gripper 12 will unfold outward. The baffle 18 slides up by the action of the irregular sliding groove 17. At this time, the warming patch moves through the bottom of the baffle 18 so that it will not obstruct the warming patch, thus improving the overall bagging efficiency of the device. At this time, a drive gear 6 is connected to the bottom of the gripper 12, and a driven gear 7 meshes with one side of the drive gear 6. A shaped cam 21 is connected to the top of the driven gear 7, and a piston cylinder 20 is provided on one side of the shaped cam 21. A lower adsorption assembly 19 that cooperates with the piston cylinder 20 is provided on one end of the bagging plate 3 at the gripper 12. By meshing with the driven gear 7, the shaped cam 21 at the top rotates. At this time, the shaped cam 21 causes the piston assembly 23 to draw gas from the piston cylinder 20, so that the lower adsorption assembly... When component 19 is in an adsorption state on the bottom of the packaging bag, the upper adsorption component 13, together with the lifting cylinder 9, drives the top of the packaging bag to move upward and open, thus completing the opening of the packaging bag. At this time, the heat patch is conveyed into the packaging bag by the first feeding belt 10. The bagging plate 3 is provided with a second feeding belt 15 on one side of the lower adsorption component 19. Under the action of the second feeding belt 15, after the heat patch is packaged, the second feeding belt 15 will transport it to the next process to prevent the heat patch itself from accumulating at the mounting frame 8.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 8The bag-retrieving component 4 includes a base plate 401, a slot 402, a second electric suction cup 403, and a collection frame 404. The base plate 401 is provided on one side of the top of the bagging plate 3, and the collection frame 404 is provided on the top of the base plate 401. The second electric suction cup 403 is slidably arranged on the bagging plate 3 in the vertical direction. The slot 402 is provided on the base plate 401 at the location of the second electric suction cup 403. The reciprocating cylinder 5 drives the gripping component 14 to move to the base plate 401. Then the gripping component 14 is in the open state. Then the second electric suction cup 403 moves upward so that it contacts the bottom of the packaging bag to complete the adsorption work. It then slides down by resetting itself so that the packaging bag is pulled out from the slot 402 of the collection frame. Since the collection frame 404 is also L-shaped, the remaining packaging bag can be stored in the collection frame 404. The above process is repeated until the packaging of the warm patch is completed.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 11 The piston assembly 23 is elastically installed inside the piston cylinder 20. A contact plate 22 that cooperates with the shaped cam 21 is connected to one side of the piston assembly 23. Under normal conditions, the piston assembly 23 is compressed inside the piston cylinder 20. When the shaped cam 21 rotates under the action of the driven gear 7, the shaped cam 21 will release the limit on the contact plate 22. At this time, under the reset action of the elastic component, the contact plate 22 is reset and slid, thereby driving the piston assembly 23 to move inside the piston cylinder 20, so that the lower adsorption component 19 adsorbs the bottom of the packaging bag.

[0034] Example 2: Please refer to Figure 5 The automatic bagging machine for producing heat patch shown has an overall structure similar to that of Embodiment 1. The feeding mechanism 2 includes a feeding cylinder 201, a first electric suction cup 202, a feeding frame 203, feeding belts 204, and a storage rack 205. The feeding frame 203 is located on one side of the feeding frame 1, and the storage rack 205 is mounted on the feeding frame 203. The storage rack 205 itself is L-shaped, and multiple feeding belts 204 are located at the storage rack 205. The feeding cylinder 201 is mounted on the feeding frame 203. The output end of 01 is equipped with a first electric suction cup 202, which stores the warming patches conveyed on the feeding rack 1 under the action of the storage rack 205. Then, with the cooperation of the feeding cylinder 201 and the first electric suction cup 202, the warming patches are uniformly conveyed to one side through the feeding belt 204, thereby ensuring that the output speed on the front feeding rack 1 is completely synchronized with the speed of the rear bagging machine. This allows the device to maintain continuous production through the buffer adjustment of the feeding mechanism 2, thereby solving the matching problem between the front and rear processes of the production line and improving the stability and efficiency of subsequent warming patch bagging.

[0035] In practical operation, the present invention is used to transport the completed heat patch to the unloading mechanism 2 via the feeding rack 1. The heat patch is stored by the storage rack 205 on the unloading mechanism 2, ensuring that the subsequent heat patches can move synchronously to the bagging plate 3. In normal state, the gripper 12 on the bagging plate 3 is inclined inward. Since the bagging plate 3 is provided with a special-shaped groove 17 at the gripper 12, the guide post 16 and the special-shaped groove 17 cause the stop bar 18 in this state to slide down to the bagging plate 3 and be perpendicular to the side of the bagging plate 3 in a horizontal state. At this time, the heat patch transported by the unloading mechanism 2 will be flush with the bag opening under the action of the stop bar 18, effectively preventing the material from being stuck in the bag during subsequent bagging. During bagging, the lifting cylinder 9 drives the upper adsorption component 13 to slide down, while the gripper 12 rotates and opens. At this time, the irregularly shaped slide groove 17 causes the guide post 16 to slide up the stop bar 18, ensuring that it will not obstruct the warming patch later. During the rotation of the gripper 12, the meshing of the bottom active gear 6 and driven gear 7 causes the irregularly shaped cam 21 to disengage from the abutment plate 22. As a result, the piston component 23, under the action of the elastic component, slides back from the piston cylinder 20 to extract the internal gas. At this time, the lower adsorption component 19 adsorbs the bottom of the packaging bag. After the upper adsorption component 13 adsorbs the top of the packaging platform, it moves up in conjunction with the lifting cylinder 9, thus completing the opening of the packaging bag. During this process, the lower adsorption component 19 limits the bottom of the packaging bag, which can effectively prevent the bottom of the packaging bag from moving up due to static electricity, ensuring that the warming patch can be inserted into the packaging bag during the bagging process, thus improving the overall bagging stability.
