Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, and in particular to a nozzle component calibration device and a packaging equipment. Background Art

[0002] At present, packaging bags for storing liquids or gases are widely used. Most of these packaging bags include a bag body and a nozzle component connected to the bag body. The nozzle component has an installation portion that is generally rhombus-shaped.

[0003] In the production process of the packaging bag, the nozzle component is generally conveyed forward by a feeding track. Before the nozzle component is welded to the bag body by plastic welding, it is necessary to deflect the installation portion to a preset angle so that the pointed ends at both ends of the installation portion point in the same direction as the width direction of the front film and the rear film of the packaging bag.

[0004] At present, there is no corresponding calibration device that can adjust the deflection angle of the nozzle component relative to the feeding track, and only manual intervention can be carried out. However, the position accuracy of the nozzle component after manual intervention is difficult to guarantee, resulting in uneven processing quality of the packaging bag and even defective products. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. For this reason, one of the purposes of the present invention is to provide a nozzle component calibration device that can accurately position the nozzle component.

[0006] Another purpose of the present invention is to provide a packaging equipment with the above-mentioned nozzle component calibration device.

[0007] A nozzle component calibration device according to an embodiment of the first aspect of the present invention includes: a feeding track, a calibration station is provided at the output end of the feeding track, and a blocking member that can abut against the nozzle component to limit the nozzle component within the calibration station. A first positioning clamp block group and a second positioning clamp block group that can drive the nozzle component to move are movably arranged on the calibration station. A clamping and positioning space that matches the installation portion of the nozzle component is defined between the first positioning clamp block group and the second positioning clamp block group.

[0008] A nozzle component calibration device according to an embodiment of the present invention has at least the following beneficial effects:

[0009] The nozzle component calibration device with the above structure conveys the nozzle component to the calibration station through the feeding track, and then uses the first positioning clamp block group and the second positioning clamp block group to cooperate with each other to limit and fix the nozzle component within the clamping and positioning space, so as to adjust the nozzle component to a preset angle and position, providing a nozzle component with accurate positioning for the subsequent process and ensuring the production and processing quality of the packaging bag.

[0010] In some embodiments of the present invention, to avoid interference when the first positioning clamp block group and the second positioning clamp block group drive the nozzle member to move respectively, the first positioning clamp block group and the second positioning clamp block group are both electrically connected to the control module, and the control module controls the first positioning clamp block group and the second positioning clamp block group to act successively to clamp and fix the nozzle member.

[0011] In some embodiments of the present invention, the first positioning clamp block group includes two first clamp blocks telescopically arranged at the calibration station. The two first clamp blocks can push the nozzle member to rotate and be clamped between two opposite positioning surfaces of the mounting portion. The second positioning clamp block group includes two second clamp blocks telescopically arranged at the calibration station. The two second clamp blocks can push the nozzle member to rotate and be clamped between the other two opposite positioning surfaces of the mounting portion. Among them, the telescopic directions of the two first clamp blocks are parallel to each other, and the telescopic directions of the two second clamp blocks are parallel to each other. When the two first clamp blocks extend towards the nozzle member, they can initially adjust the deflection angle of the mounting portion of the nozzle member. When the two second clamp blocks extend towards the nozzle member, they can finally adjust the deflection angle and position of the mounting portion of the nozzle member, so that the mounting portion is located within the clamping and positioning space surrounded by the two first clamp blocks and the two second clamp blocks. The first positioning clamp block group and the second positioning clamp block group have a simple structure, a stable and reliable movement mode, and a relatively high positioning accuracy.

[0012] In some embodiments of the present invention, a first guiding groove extending towards the calibration station and matching the first clamp block is provided on the material guiding track. The first clamp block can extend along the first guiding groove to contact the tip of the mounting portion to drive the nozzle member to rotate. A second guiding groove extending towards the calibration station and matching the second clamp block is provided on the material guiding track. The second clamp block can extend along the second guiding groove to contact the tip of the mounting portion to drive the nozzle member to rotate. The first guiding groove is beneficial to improving the accuracy of the telescopic movement of the first clamp block, and the second guiding groove is beneficial to improving the accuracy of the telescopic movement of the second clamp block.

[0013] In some embodiments of the present invention, the blocking member is rotatably connected to the side of the material guiding track through a pivot, and an elastic member is connected to the pivot to drive the blocking member to abut against the side surface of the nozzle member. When the nozzle member on the material guiding track moves to contact the blocking member, under the action of the elastic member, the nozzle member cannot continue to be conveyed forward. At this time, the first positioning clamp block group and the second positioning clamp block group intervene to adjust the nozzle member to a preset position, and then an external manipulator or other conveying device clamps the positioned nozzle member and conveys the nozzle member to the next process. During the process of conveying the nozzle member to the next process, the nozzle member pushes open the blocking member, and the blocking member rotates a certain angle against the action of the elastic member. When the clamped nozzle member is separated from the blocking member, the blocking member resets under the action of the elastic member, so as to continue to block another nozzle member that has not been positioned and adjusted.

[0014] In some embodiments of the present invention, a limiting column capable of abutting against the side portion of the blocking member is provided on one side of the blocking member, and an arc-shaped guiding surface matching the contour shape of the nozzle member is provided on the blocking member. The limiting column can limit the rotation angle of the blocking member generated under the action of the elastic member, avoiding excessive rotation of the blocking member so that the nozzle member cannot enter the calibration station; for the case where the contour shape of the nozzle member has a cylindrical surface, the arc-shaped guiding surface can not only block the nozzle member from continuing to move forward, but also guide the rotational movement of the nozzle member.

[0015] In some embodiments of the present invention, a clamping and conveying mechanism corresponding to the calibration station is movably arranged below the material guiding track, and the clamping and conveying mechanism includes a translation mechanism reciprocating along the conveying direction of the material guiding track and a pneumatic gripper connected to the translation mechanism. After the position of the nozzle member is calibrated, the pneumatic gripper is used to clamp the nozzle member, and then the nozzle member can be moved to the next process through the translation mechanism, with a simple structure and low cost.

[0016] In some embodiments of the present invention, in order to ensure that the calibrated nozzle member will not generate relative displacement and guarantee the quality after the nozzle member is connected to the bag body, the nozzle member calibration device includes a positioning fixture, and the positioning fixture can move to a position opposite to the output end of the material guiding track, and the translation mechanism can push the nozzle member into the positioning fixture.

[0017] In some embodiments of the present invention, the nozzle member calibration device further includes a mounting base plate. The material guiding track includes a first half-track and a second half-track that are relatively spaced apart on the mounting base plate. The first half-track has a first notch with an opening facing the second half-track, and the second half-track has a second notch with an opening facing the first half-track. A transmission channel is defined between the first notch and the second notch, and the transmission channel includes a first guiding channel with a groove width matching the distance between the two opposing positioning surfaces of the mounting portion. When the mounting portion of the nozzle member passes through the first guiding channel, the tip portion of the mounting portion does not contact the inner wall of the first guiding channel. The first guiding channel can limit the deflection angle of the mounting portion of the nozzle member relative to the material guiding track within a certain range, facilitating subsequent calibration.

[0018] The present invention also discloses a packaging device, including the nozzle member calibration device described in any of the above technical solutions. This packaging device helps to improve the processing quality and stability of packaging bags and improve production efficiency.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See Figure 1 and Figure 4 , a nozzle element calibration device according to an embodiment of the present invention includes: a feeding track 100, a calibration station is provided at the output end of the feeding track 100, and a blocking member 200 that can abut against the nozzle element 10 to limit the nozzle element 10 within the calibration station. A first positioning clamp block group 300 and a second positioning clamp block group 400 that can drive the movement of the nozzle element 10 are movably arranged at the calibration station. A clamping and positioning space matching the installation portion 11 of the nozzle element 10 is defined between the first positioning clamp block group 300 and the second positioning clamp block group 400.

[0030] The nozzle element calibration device with the above structure transports the nozzle element 10 to the calibration station through the feeding track 100, and then uses the first positioning clamp block group 300 and the second positioning clamp block group 400 to cooperate with each other to limit and fix the nozzle element 10 within the clamping and positioning space, so as to adjust the nozzle element 10 to a preset angle and position, and provide a nozzle element 10 with accurate positioning for the subsequent process, ensuring the production and processing quality of the packaging bag.

[0031] In some embodiments of the present invention, to avoid interference when the first positioning clamp block group 300 and the second positioning clamp block group 400 drive the nozzle member 10 respectively, the first positioning clamp block group 300 and the second positioning clamp block group 400 are both electrically connected to the control module, and the control module controls the first positioning clamp block group 300 and the second positioning clamp block group 400 to act successively to clamp and fix the nozzle member 10.

[0032] See Figure 1 , in some embodiments of the present invention, the first positioning clamp block group 300 includes two first clamp blocks 310 that are telescopically arranged at the calibration station. The two first clamp blocks 310 can push the nozzle member 10 to rotate and be clamped between two opposite positioning surfaces 111 of the mounting portion 11; the second positioning clamp block group 400 includes two second clamp blocks 410 that are telescopically arranged at the calibration station. The two second clamp blocks 410 can push the nozzle member 10 to rotate and be clamped between the other two opposite positioning surfaces 111 of the mounting portion 11. Among them, the telescopic directions of the two first clamp blocks 310 are parallel, and the telescopic directions of the two second clamp blocks 410 are parallel. When the two first clamp blocks 310 extend towards the nozzle member 10, they can initially adjust the deflection angle of the mounting portion 11 of the nozzle member 10. When the two second clamp blocks 410 extend towards the nozzle member 10, they can finally adjust the deflection angle and position of the mounting portion 11 of the nozzle member 10 so that the mounting portion 11 is located within the clamping and positioning space surrounded by the two first clamp blocks 310 and the two second clamp blocks 410. The first positioning clamp block group 300 and the second positioning clamp block group 400 have a simple structure, a stable and reliable movement mode, and a relatively high positioning accuracy. Among them, the first positioning clamp block group 300 and the second positioning clamp block group 400 drive the nozzle member 10 to rotate in the same direction. For example, as Figure 1 shown, the two first clamp blocks 310 drive the nozzle member 10 to rotate counterclockwise by a certain angle to achieve the initial adjustment, and then the two second clamp blocks 410 drive the nozzle member 10 to rotate counterclockwise by a certain angle or translate slightly to achieve the position positioning. In this embodiment, the first clamp block 310 and the second clamp block 410 are both driven by cylinders to achieve telescopic movement. Of course, in other embodiments, the cylinder can also be replaced by a linear actuator such as an electric push rod.

[0033] See Figure 1 and Figure 2, in some embodiments of the present invention, a first guiding groove 110 extending towards the calibration station and matching with the first clamping block 310 is provided on the material guiding track 100. The first clamping block 310 can extend along the first guiding groove 110 to contact the tip of the mounting portion 11 to drive the nozzle member 10 to rotate; a second guiding groove 120 extending towards the calibration station and matching with the second clamping block 410 is provided on the material guiding track 100. The second clamping block 410 can extend along the second guiding groove 120 to contact the tip of the mounting portion 11 to drive the nozzle member 10 to rotate. The first guiding groove 110 is beneficial to improving the accuracy of the telescopic movement of the first clamping block 310, and the second guiding groove 120 is beneficial to improving the accuracy of the telescopic movement of the second clamping block 410.

[0034] See Figure 1 , in some embodiments of the present invention, the blocking member 200 is rotatably connected to the side of the material guiding track 100 through a pivot 210. The pivot 210 is connected with an elastic member for driving the blocking member 200 to abut against the side surface of the nozzle member 10. Here, the elastic member is a torsion spring sleeved on the pivot 210. When the nozzle member 10 on the material guiding track 100 moves to contact the blocking member 200, under the action of the elastic member, the nozzle member 10 cannot continue to be conveyed forward. At this time, the first positioning clamping block group 300 and the second positioning clamping block group 400 intervene to adjust the nozzle member 10 to a preset position, and then an external manipulator or other conveying device clamps the positioned nozzle member 10 and conveys the nozzle member 10 to the next process. During the process of conveying the nozzle member 10 to the next process, the nozzle member 10 pushes open the blocking member 200, and the blocking member 200 rotates a certain angle against the action of the elastic member. When the clamped nozzle member 10 is separated from the blocking member 200, the blocking member 200 resets under the action of the elastic member, so as to continue to block another uncalibrated nozzle member 10.

[0035] See Figure 1 , in some embodiments of the present invention, a limiting post 220 capable of abutting against the side of the blocking member 200 is provided on one side of the blocking member 200, and an arc-shaped guiding surface 201 matching the contour shape of the nozzle member 10 is provided on the blocking member 200. The limiting post 220 can limit the rotation angle of the blocking member 200 generated under the action of the elastic member, avoiding the blocking member 200 from rotating excessively and causing the nozzle member 10 to be unable to enter the calibration station; for the case where the contour shape of the nozzle member 10 has a cylindrical surface, the arc-shaped guiding surface 201 can not only block the nozzle member 10 from continuing to move forward, but also guide the rotational movement of the nozzle member 10.

[0036] See Figure 2 and Figure 3, in some embodiments of the present invention, a clamping and conveying mechanism 500 corresponding to the calibration station is movably arranged below the material guiding track 100. The clamping and conveying mechanism 500 includes a translation mechanism 510 that reciprocates along the conveying direction of the material guiding track 100 and a pneumatic gripper 520 connected to the translation mechanism 510. After the position of the nozzle member 10 is calibrated, the pneumatic gripper 520 is used to clamp the nozzle member 10, and then the nozzle member 10 can be moved to the next process through the translation mechanism 510. The structure is simple and the cost is relatively low. In this embodiment, the translation mechanism 510 includes a cylinder and a push plate connected to the output end of the cylinder, and the pneumatic gripper 520 is arranged on the push plate; of course, in other embodiments, the translation mechanism 510 can also be replaced by a linear actuator such as an electric push rod.

[0037] See Figure 3 , in some embodiments of the present invention, in order to ensure that the calibrated nozzle member 10 will not produce relative offset and guarantee the quality after the nozzle member 10 is connected to the bag body, the nozzle member calibration device includes a positioning fixture 600. The positioning fixture 600 can move to a position opposite to the output end of the material guiding track 100, and the translation mechanism 510 can push the nozzle member 10 into the positioning fixture 600.

[0038] See Figure 1 , in some embodiments of the present invention, the nozzle member calibration device further includes a mounting base plate 700. The material guiding track 100 includes a first half-track 101 and a second half-track 102 that are relatively and spaced apart on the mounting base plate 700. The first half-track 101 has a first notch with an opening facing the second half-track 102, and the second half-track 102 has a second notch with an opening facing the first half-track 101. A transmission channel is defined between the first notch and the second notch. The transmission channel includes a first guiding channel 103 whose groove width matches the distance between the two positioning surfaces 111 of the opposite mounting portion 11. When the mounting portion 11 of the nozzle member 10 passes through the first guiding channel 103, the tip of the mounting portion 11 will not contact the inner wall of the first guiding channel 103. The first guiding channel 103 can limit the deflection angle of the mounting portion 11 of the nozzle member 10 relative to the material guiding track 100 within a certain range, so as to facilitate subsequent calibration.

[0039] The present invention also discloses a packaging device, including the nozzle member calibration device described in any of the above technical solutions. This packaging device helps to improve the processing quality and stability of the packaging bag and improve the production efficiency.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
