Description

Technical Field

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

[0002] Currently, when packaging products, after the product is placed inside the bag, the opening of the bag is usually placed directly between the upper and lower hot press heads of the hot press device. The bag opening is sealed by the mutual clamping of the upper and lower hot press heads. However, this method is affected by the shape of the product. As the upper hot press head gradually approaches the lower hot press head, the shape of the bag opening changes, resulting in local overlap and wrinkles. This leads to unevenness at the sealing line, and the overlapping parts are also prone to sealing failure due to insufficient hot press temperature, resulting in air leakage. Utility Model Content

[0003] The purpose of this invention is to provide a packaging device that can ensure that the opening shape of the bag remains unchanged during the hot pressing process, resulting in a smoother packaging line and reducing or even avoiding the phenomenon of air leakage due to packaging failure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model provides a packaging device, including a first driving mechanism, a support platform, a hot pressing device, and multiple clamping components;

[0006] The first drive mechanism is connected to the support platform, and the first drive mechanism is configured to drive the support platform to reciprocate in the horizontal direction;

[0007] Each of the clamping components is sequentially installed on the support platform along a direction perpendicular to the movement of the support platform, and the clamping component includes an upper jaw and a lower jaw;

[0008] The hot pressing device is located on one side of the support platform along the direction of movement of the support platform.

[0009] When the packaging equipment provided by this utility model is in use, the first driving mechanism can drive the support platform and the clamping components on the support platform to approach the bag body. The upper and lower clamping jaws of at least two clamping components can clamp the edge of the bag body, so that the opening of the bag body remains flat. The hot pressing device on the side of the support platform can hot press and seal the bag body. The clamping components can ensure that the opening shape of the bag body remains unchanged during the hot pressing process, resulting in a flatter sealing line and reducing or even avoiding the phenomenon of air leakage due to sealing failure of the bag body.

[0010] Furthermore, both the upper gripper and the lower gripper include an extension portion and a clamping portion connected at an angle to the extension portion, wherein the extension direction of the extension portion is parallel to the direction of movement of the support platform.

[0011] Since the clamping part and the extension part are connected at an angle, it is easy for the user to observe the position of the edge of the bag held by the clamping part.

[0012] Furthermore, the clamping assembly includes a lifting structure, which is mounted on the support platform. At least one of the upper jaw and the lower jaw is connected to the lifting structure and configured to adjust the clamping force under the action of the lifting structure.

[0013] The above-mentioned lifting structure configuration enables the clamping components to automatically adjust the clamping force, improves packaging efficiency, and reduces the workload of personnel.

[0014] Furthermore, the lifting structure in at least one of the clamping components is adjustable relative to the support platform in a direction perpendicular to the movement of the support platform.

[0015] The above configuration enables the clamping mechanism, composed of multiple clamping components, to automatically adapt to bags with different opening widths.

[0016] Furthermore, the packaging device also includes a plurality of bag-strapping plates installed between any two of the clamping components, with one end of each bag-strapping plate sequentially installed on the support platform along a direction perpendicular to the movement of the support platform, and the distance between any two bag-strapping plates is configured to be adjustable.

[0017] In use, the first drive mechanism can drive the support platform, the two bag-strapping plates on the support platform, and the two clamping components to move forward. The two bag-strapping plates extend into the bag body. By moving left and right to adjust the distance between the two bag-strapping plates inside the bag body, the bag-strapping plates can flatten the opening of the bag body. Then, the upper and lower jaws in the two clamping components clamp the edges on both sides of the bag body onto the two bag-strapping plates respectively, ensuring the stability of the bag body edges relative to the bag-strapping plates. During the vacuuming process, the bag body edges are not easy to detach from the bag-strapping plates.

[0018] Furthermore, in any two adjacent bag-strapping plates, the opposite edges of the two bag-strapping plates have narrowed portions, and the upper gripper and the lower gripper are configured to clamp the narrowed portions.

[0019] The above method allows the thickness of the bag-strapping plate used to flatten the edge of the bag to become thinner closer to the bag body. When the bag body is opened, the two ends of the side of the bag body can gradually form a gap towards the middle through the bag-strapping plate, which facilitates vacuuming.

[0020] Furthermore, the packaging device also includes a vacuum tube mounted on the support platform, the vacuum tube being positioned adjustable along a direction parallel to the movement of the support platform.

[0021] The vacuum tube enables vacuuming of the bag. Furthermore, since the position of the vacuum tube is adjustable along the direction parallel to the movement of the support platform, it can continue to penetrate deeper into the bag after the bag is flattened by the bag-straightening plate, so as to extract the gas from the bag more quickly during operation.

[0022] Furthermore, it also includes a main support, on which the hot pressing device and the first drive mechanism are jointly mounted.

[0023] In the above solution, the use of the bag-straightening plate and the clamping mechanism does not affect the hot pressing of the hot pressing device. While ensuring that the bag is in a flat state, the hot pressing device performs hot pressing and sealing on the bag to avoid the bag from failing to seal and leaking air.

[0024] Furthermore, the hot pressing device includes an upper hot pressing frame and a lower hot pressing frame disposed opposite to the upper hot pressing frame, at least one of the upper hot pressing frame and the lower hot pressing frame being configured to move in a vertical direction.

[0025] In the aforementioned hot pressing device, at least one of the upper and lower hot pressing frames is configured to move vertically to facilitate hot pressing and sealing of the bag.

[0026] Furthermore, the packaging device also includes a cooling pipe mounted on the support platform, the cooling pipe having air blowing holes.

[0027] The cooling pipes can quickly cool the bags after hot pressing, allowing them to proceed to the next process quickly. Attached Figure Description

[0040] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0041] This embodiment provides a packaging device, such as... Figure 1 and Figure 2 As shown, it includes a first drive mechanism 1, a support platform 2, a hot pressing device 9, and multiple clamping components;

[0042] The first drive mechanism 1 is connected to the support platform 2, and the first drive mechanism 1 is configured to drive the support platform 2 to reciprocate in the horizontal direction.

[0043] Each clamping component is sequentially installed on the support platform 2 along a direction perpendicular to the movement of the support platform 2. The clamping components include an upper jaw 611 and a lower jaw 612.

[0044] The hot pressing device 9 is set on one side of the support platform 2 along the direction of movement of the support platform 2.

[0045] The working process of the above packaging device will be explained in detail using an example of two clamping components:

[0046] When using, such as Figure 1As shown, the first driving mechanism 1 can drive the support platform 2 and the clamping components on the support platform 2 to move forward and approach the bag body. The upper jaw 611 and the lower jaw 612 in the two clamping components can clamp the edges on both sides of the bag body 3 respectively, so that the opening of the bag body 3 remains flat. The hot pressing device 9 on the side of the support platform 2 can perform hot pressing and sealing on the bag body 3. The clamping components can ensure that the opening shape of the bag body 3 remains unchanged during the hot pressing process, resulting in a flatter sealing line and reducing or even avoiding the phenomenon of air leakage due to sealing failure of the bag body.

[0047] When the packaging device includes two or more clamping components, each side of the bag body 3 can be clamped by at least one clamping component, thereby ensuring that each side of the bag body 3 can be clamped. When a side is clamped by multiple clamping components, the clamping positions can be distributed from the open end of the bag body 3 toward the end of the bag body 3 away from the opening.

[0048] It should be noted that any structure that can drive the support platform 2 to reciprocate in the direction of approaching or moving away from the bag body 3 can be the first drive mechanism 1 mentioned in the above embodiments. For example, the first drive mechanism 1 can include an electric cylinder, a linear motor, etc. that perform linear motion, or it can be a combination of a drive component that performs rotational motion and a transmission component. The transmission component can convert rotational motion into linear motion. The transmission component can be, but is not limited to, a crank-slider assembly, a lead screw-nut assembly, etc.

[0049] In a preferred embodiment, such as Figure 1 As shown, the first drive mechanism 1 includes an electric cylinder. The cylinder body is mounted on the base plate of the main support 10. The movable end of the electric cylinder is connected to the support platform 2. The base plate is provided with a first slide rail 101. The support platform 2 slides in cooperation with the first slide rail 101 through a slider. The first slide rail 101 can guide the movement of the support platform 2 relative to the bag body 3.

[0050] Specifically, the first slide rail 101 can be configured as two.

[0051] In alternative implementations, such as Figure 3 As shown, both the upper gripper 611 and the lower gripper 612 include an extension 6111 and a clamping part 6112 connected at an angle to the extension 6111. The extension direction of the extension 6111 is parallel to the direction of movement of the support platform 2, and the clamping part 6112 is configured to clamp the edge of the bag body 3.

[0052] In the above embodiments, since the clamping part 6112 and the extension part 6111 are connected at an angle, it is convenient for the user to observe the position of the edge of the bag body 3 clamped by the clamping part 6112.

[0053] The clamping part 6112 may have a clamping block protruding on the surface for clamping the bag body 3. The clamping block can clamp the edge of the bag body 3, so that the force of the clamping part 6112 acting on the edge of the bag body 3 is more concentrated.

[0054] In alternative implementations, such as Figure 3 As shown, the clamping assembly includes a lifting structure 613, which is mounted on the support platform 2. At least one of the upper jaw 611 and the lower jaw 612 is connected to the lifting structure 613 and configured to adjust the clamping force under the drive of the lifting structure 613.

[0055] When the upper jaw 611 or the lower jaw 612 is connected to the lifting structure 613, the lifting structure 613 can move one of the connected jaws away from or closer to the other to adjust the distance between the upper jaw 611 and the lower jaw 612, thereby achieving automatic adjustment of the clamping force.

[0056] When both the upper gripper 611 and the lower gripper 612 are connected to the lifting structure 613, the upper gripper 611 and the lower gripper 612 move in opposite directions. This method can accelerate the adjustment of the distance between the upper gripper 611 and the lower gripper 612, thereby increasing the clamping and releasing speed of the bag body 3 by the clamping mechanism 6.

[0057] The lifting structure 613 may include an electric cylinder or linear motor that performs linear motion, or it may be a combination of a drive component and a transmission assembly that performs rotary motion. The transmission assembly can convert rotary motion into linear motion. The transmission assembly may, but is not limited to, a crank-slider assembly or a lead screw-nut assembly.

[0058] In a preferred embodiment, the lifting structure 613 includes an electric cylinder, the cylinder body of which is mounted on the support platform 2, and the movable end of the electric cylinder is connected to the upper gripper 611 and / or the lower gripper 612.

[0059] In an optional embodiment, the lifting structure 613 in at least one clamping assembly is adjustable relative to the support platform 2 in a direction perpendicular to the movement of the support platform 2, so that the clamping mechanism 6 composed of multiple clamping assemblies can automatically adapt to bags 3 with different opening widths.

[0060] Specifically, with Figure 4 Taking this as an example, the clamping mechanism 6 includes a first clamping component 61 and a second clamping component 62. The packaging device includes a third driving mechanism 011. At least one of the first clamping component 61 and the second clamping component 62 is connected to the third driving mechanism 011. The third driving mechanism 011 is configured to drive the first clamping component 61 and / or the second clamping component 62 connected to it to slide relative to the second slide rail 22 on the support platform 2. The second slide rail 22 extends horizontally and is perpendicular to the direction in which the first driving mechanism 1 drives the support platform 2 to move, so that the clamping mechanism 6 can automatically adapt to bags 3 with different opening widths.

[0061] Preferably, both the first clamping component 61 and the second clamping component 62 are connected to the third drive mechanism 011, and the first clamping component 61 and the second clamping component 62 move in opposite directions. This method can accelerate the adjustment of the distance between the first clamping component 61 and the second clamping component 62, thereby increasing the rate at which the edge of the bag body 3 is clamped.

[0062] The third drive mechanism 011 may include an electric cylinder or linear motor that performs linear motion, or it may be a combination of a drive component and a transmission assembly that performs rotary motion, such as a motor. The transmission assembly can convert rotary motion into linear motion. The transmission assembly may, but is not limited to, a crank-slider assembly or a lead screw-nut assembly.

[0063] Based on the above implementation, the lifting structure 613 can be installed on the third drive mechanism 011. The third drive mechanism 011 drives the lifting structure 613 to slide along the second slide rail 22. The upper gripper 611 and the lower gripper 612 are both connected to the third drive mechanism 011 through the lifting structure 613.

[0064] In alternative implementations, such as Figure 5 and Figure 6 As shown, the packaging equipment also includes multiple bag-strapping plates 4 installed between any two clamping components. One end of each bag-strapping plate 4 is sequentially installed on the support platform 2 in a direction perpendicular to the movement of the support platform 2, and the distance between any two bag-strapping plates 4 is configured to be adjustable so that the other end of the bag-strapping plate 4 flattens the opening of the bag body 3 from inside the bag body 3.

[0065] Taking an example where both the bag-strapping plate 4 and the clamping assembly are configured in pairs, the working process of the above-mentioned packaging equipment will be explained in detail:

[0066] In use, the first drive mechanism 1 can drive the support platform 2, the two bag-strapping plates 4 on the support platform 2, and the two clamping components to move forward. The two bag-strapping plates 4 extend into the bag body 3. By moving left and right to adjust the distance between the two bag-strapping plates 4 in the bag body 3, the bag-strapping plates 4 can flatten the opening of the bag body. Then, the upper jaw 611 and the lower jaw 612 in the two clamping components clamp the edges on both sides of the bag body 3 onto the two bag-strapping plates 4, respectively, to ensure the stability of the edges of the bag body 3 relative to the bag-strapping plates 4. During the vacuuming process, the edges of the bag body 3 are not easy to detach from the bag-strapping plates 4.

[0067] When there are two or more bag-strapping plates 4, the shapes of each bag-strapping plate 4 can be different to accommodate bags 3 of different specifications and materials. When in use, two suitable bag-strapping plates 4 can be selected to extend into the bag 3 to flatten the bag 3.

[0068] In alternative implementations, such as Figure 6 and Figure 7 As shown, the plurality of bag-strapping plates 4 include a first bag-strapping plate 41 and a second bag-strapping plate 42. The support platform 2 is provided with a second drive mechanism 5 connected to at least one of the first bag-strapping plate 41 and the second bag-strapping plate 42. The second drive mechanism 5 is configured to drive the first bag-strapping plate 41 and / or the second bag-strapping plate 42 connected thereto to move in a direction perpendicular to the movement of the support platform 2.

[0069] The second drive mechanism 5 enables automatic adjustment of the distance between the first bag-strapping plate 41 and the second bag-strapping plate 42, thereby improving sealing efficiency and reducing manual workload.

[0070] When the first bag-strapping plate 41 or the second bag-strapping plate 42 is connected to the second drive mechanism 5, the second drive mechanism 5 can drive one of the connected parts to move away from or closer to the other, so as to adjust the distance between the first bag-strapping plate 41 and the second bag-strapping plate 42, thereby opening the bag body 3 and releasing the bag body 3.

[0071] When both the first bag-strapping plate 41 and the second bag-strapping plate 42 are connected to the second drive mechanism 5, the first bag-strapping plate 41 and the second bag-strapping plate 42 move in opposite directions. This method can accelerate the adjustment of the distance between the first bag-strapping plate 41 and the second bag-strapping plate 42, thereby increasing the rate at which the bag body 3 is flattened.

[0072] The second drive mechanism 5 may include electric cylinders. When both the first bag-strapping plate 41 and the second bag-strapping plate 42 are connected to the second drive mechanism 5, two electric cylinders may be configured to be connected to the first bag-strapping plate 41 and the second bag-strapping plate 42 respectively.

[0073] like Figure 7 As shown, the second drive mechanism 5 may also include a power source 51 and a lead screw 52.

[0074] Specifically, a support 21 is provided on the support platform 2, and a power source 51 is installed on the support 21. The power source 51 is connected to the lead screw 52 and configured to drive the lead screw 52 to rotate relative to the support platform 2. The rotation axis of the lead screw 52 is parallel to the top surface of the support platform 2. The first bag-strapping plate 41 and the second bag-strapping plate 42 are both threadedly engaged with the lead screw 52 and slidably engaged with the support platform 2 in a direction perpendicular to the movement of the support platform 2.

[0075] In use, the power source 51 drives the lead screw 52 to rotate. Since the first bag-strapping plate 41 and the second bag-strapping plate 42 are both threadedly engaged with the lead screw 52 and slidably engaged with the support platform 2 in a direction perpendicular to the movement of the support platform 2, the rotation of the lead screw 52 can realize the relative movement of the first bag-strapping plate 41 and the second bag-strapping plate 42.

[0076] Understandably, in order to make the first bag-strapping plate 41 and the second bag-strapping plate 42 move in opposite directions, the direction of rotation of the thread on the lead screw 52 that mates with the first bag-strapping plate 41 is opposite to the direction of rotation of the thread on the lead screw 52 that mates with the second bag-strapping plate 42.

[0077] The aforementioned second drive mechanism 5 adopts a power source 51 and a lead screw 52, ​​which not only enables the movement of the first bag-strapping plate 41 and the second bag-strapping plate 42 through a single power source 51, but also ensures the movement accuracy of the first bag-strapping plate 41 and the second bag-strapping plate 42 through the threaded connection.

[0078] The aforementioned power source 51 can be an electric motor. To reduce the area occupied by the second drive mechanism 5 along the axial direction of the lead screw 52, ​​such as... Figure 4 As shown, the power source 51 includes a motor 511 and a transmission assembly 512. The transmission assembly 512 can be a gear transmission assembly, a belt transmission assembly, or a chain transmission assembly, etc.

[0079] Taking the transmission assembly 512 as an example, the transmission assembly 512 includes a drive wheel connected to the power output shaft of the motor 511, a driven wheel connected to the lead screw 52, ​​and a belt wound between the drive wheel and the driven wheel. When the motor 511 rotates, it can drive the drive wheel to rotate, and through the belt transmission, it can drive the driven wheel and the lead screw 52 connected to the driven wheel to rotate.

[0080] like Figure 4 As shown, the motor 511 and the lead screw 52 are located on the same side of the support 21, and the transmission assembly 512 is located on the other side of the support 21, which can effectively reduce the area occupied by the second drive mechanism 5 along the axial direction of the lead screw 52.

[0081] In alternative implementations, such as Figure 7 As shown, both the first bag-strapping plate 41 and the second bag-strapping plate 42 have a sliding seat 44. The sliding seat 44 is threadedly engaged with the lead screw 52 and also slidably engaged with the second slide rail 22 on the support platform 2, so that when the lead screw 52 rotates, it can stably drive the first bag-strapping plate 41 and the second bag-strapping plate 42 to move towards or away from each other.

[0082] The plates used to open the bag body 3 in the first bag-strapping plate 41 and the second bag-strapping plate 42 can be detachably connected to their respective sliding seats 44 by screws. The plates can be provided with waist-shaped grooves along the direction in which the first drive mechanism 1 drives the support platform 2 to move, so that the position of the plates relative to the sliding seats 44 is adjustable.

[0083] In an optional embodiment, in any two adjacent bag-straightening plates 4, the opposite edges of the two bag-straightening plates 4 have narrowed portions 43, and the upper gripper 611 and the lower gripper 612 are configured to clamp the edge of the bag body 3 in the narrowed portions 43.

[0084] by Figure 6 For example, the first bag-strapping plate 41 has a narrowed portion 43 at its edge away from the second bag-strapping plate 42, and the thickness of the narrowed portion 43 is smaller the closer it is to the side end face of the first bag-strapping plate 41; the second bag-strapping plate 42 has a narrowed portion 43 at its edge away from the first bag-strapping plate 41, and the thickness of the narrowed portion 43 is smaller the closer it is to the side end face of the second bag-strapping plate 42.

[0085] The above method allows the thickness of the bag-strapping plate 4 used to flatten the edge of the bag body 3 to be thinner as it gets closer to the bag body 3. When the bag body 3 is opened, the two ends of the side of the bag body 3 can gradually form a gap towards the middle through the bag-strapping plate 4, which facilitates vacuuming.

[0086] In alternative implementations, such as Figure 7 As shown, the packaging equipment also includes a vacuum tube 7 mounted on the support platform 2, and the position of the vacuum tube 7 along the direction of movement parallel to the support platform 2 is adjustable.

[0087] The vacuum tube 7 enables the bag body 3 to be vacuumed. Since the position of the vacuum tube 7 is adjustable along the direction parallel to the movement of the support platform 2, after the bag plate 4 flattens the bag body 3, the vacuum tube 7 can continue to penetrate the bag body 3, so as to extract the gas in the bag body 3 more quickly during operation.

[0088] The movement of the vacuum tube 7 can be achieved through structures such as electric cylinders and linear motors.

[0089] In alternative implementations, such as Figure 7 As shown, the vacuum tube 7 is positioned between the first bag-straightening plate 41 and the second bag-straightening plate 42. When the first bag-straightening plate 41 and the second bag-straightening plate 42 flatten the bag body 3, the vacuum tube 7 can continue to penetrate into the bag body 3 from between the first bag-straightening plate 41 and the second bag-straightening plate 42 to draw gas from the bag body 3.

[0090] In alternative implementations, such as Figure 6 and Figure 7 As shown, the vacuum tube 7 includes an outlet end 71 and an intake end 72 connected to the outlet end 71. The outlet end 71 is installed on the support platform 2 and has a circular cross-section. The intake end 72 has a flat ring cross-section. The outer ring of the flat ring has a major diameter and a minor diameter perpendicular to the major diameter. The major diameter is parallel to the distance adjustment direction of the bag-strapping plate 4.

[0091] In the above embodiments, the cross-section of the air outlet 71 is annular to facilitate the connection between the air outlet 71 and the air extraction device, and the cross-section of the air intake 72 is a flat ring to allow the short diameter of the air intake 72 to adapt to the gap size supported by the first bag-straightening plate 41 and the second bag-straightening plate 42, while ensuring that the air intake 72 has a large air intake cross-section and improves the suction efficiency.

[0092] In alternative implementations, such as Figure 5 As shown, the packaging equipment also includes a cooling pipe 8 mounted on the support platform 2. The cooling pipe 8 has an air blowing hole configured to blow air into the hot-pressed bag 3.

[0093] The cooling pipe 8 can quickly cool the bag 3 after hot pressing by blowing air, so that the bag 3 can quickly enter the next process.

[0094] Specifically, there are multiple air blowing holes, which can be arranged at equal intervals along the extension direction of the cooling pipe 8.

[0095] In alternative implementations, such as Figure 5 As shown, the hot pressing device 9 and the first driving mechanism 1 are jointly installed on the main support 10, and the hot pressing device 9 is arranged on one side of the support platform 2 along the movement direction of the support platform 2.

[0096] When in use, after the vacuum tube 7 has finished evacuating the vacuum, it is pulled back a certain distance, and the hot pressing device 9 can hot press and seal the bag body 3.

[0097] In the above embodiments, the use of the bag-straightening plate 4 and the clamping mechanism 6 does not affect the hot pressing of the hot pressing device 9. While ensuring that the bag body 3 is in a flat state, the hot pressing device 9 performs hot pressing and sealing on the bag body 3 to avoid the bag body 3 from failing to seal and leaking air.

[0098] Among them, such as Figure 5 As shown, the hot pressing device 9 may include an upper hot pressing frame 91 and a lower hot pressing frame 92 disposed opposite to the upper hot pressing frame 91. At least one of the upper hot pressing frame 91 and the lower hot pressing frame 92 is configured to move in the vertical direction to facilitate the hot pressing and sealing of the bag body 3.

[0099] Specifically, the upper heat press frame 91 is mounted on the main support 10 by a drive mechanism such as an electric cylinder. Driven by the electric cylinder, the upper heat press frame 91 can move toward the lower heat press frame 92, thereby heat pressing the bag body 3.

[0100] Of course, the height of the lower heat press frame 92 can also be adjusted by a drive mechanism such as an electric cylinder, so that it can move in the same direction or away from the upper heat press frame 91 to achieve heat pressing and release of the bag body 3.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
