Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, specifically to a high-efficiency film bag conveying device and a laminating machine equipped with the device. Background Technology

[0002] In the automated packaging industry, the forming and opening of film bags are critical processes that directly affect the efficiency of the entire production line. Existing bag-opening devices typically employ a step-by-step structure of "forming-setting-transfer-opening," which presents the following problems:

[0003] The dispersed layout of the mechanism means that the film bag needs to pass through multiple sets of transmission components to transfer from the forming mechanism to the opening mechanism. The path is long and time-consuming, resulting in a long interval between processes, which makes it difficult to meet the needs of high-speed production.

[0004] Relying on a single clamping component during the transfer process can easily lead to film bag shifting and wrinkling, requiring additional adjustments during subsequent bag opening, which further reduces efficiency.

[0005] The bag opening mechanism and the forming mechanism have poor coordination. They mostly adopt a fixed station design, and the next process can only be started after the previous process is completed. It is impossible to achieve synchronous connection of "forming-transfer-bag opening", resulting in low overall equipment utilization.

[0006] To address the aforementioned efficiency bottlenecks, it is necessary to design a compact, highly coordinated, and efficient film bag transport device capable of simultaneous operation of multiple processes. Summary of the Invention

[0033] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please see the appendix Figures 1 to 5 As shown: A high-efficiency bag opening device includes a film bag forming mechanism 1 and a rotary switching mechanism 2; a pull belt mechanism 3 is movably provided between the film bag forming mechanism 1 and the rotary switching mechanism 2, forming a compact layout of "film bag forming-transfer-switching" to reduce the film bag transfer path; wherein: after the pull belt mechanism 3 grasps the film bag formed on the film bag forming mechanism 1, it pulls it to the rotary switching mechanism 2 and quickly puts it onto the bag clamping component on the rotary switching mechanism 2. Then, while the rotary switching mechanism 2 rotates 180°, the pull belt mechanism 3 moves in the opposite direction to reset, preparing for the next time the pull belt mechanism 3 grasps the film bag formed on the film bag forming mechanism 1, realizing the orderly "transfer-switching-reset" process and shortening the single-process cycle time.

[0035] Based on the above embodiments, the film bag forming mechanism 1 includes a horizontally placed base 13; a screw drive assembly 14 is rotatably mounted on the base 13, and a side bag feeding component 15 and a sealing component 16 are movably mounted on the base 13; the screw drive assembly 14 can drive the side bag feeding component 15 to move closer to or away from the sealing component 16, realizing flexible adjustment of the film bag forming size; a bag opening adjustment clamping component 12 is movably mounted at one end of the side bag feeding component 15; and a bag opening is fixed at one end of the sealing component 16.

When the lead screw drive assembly 14 drives the side bag conveying component 15 to approach the sealing component 16, one end of the bag opening adjustment clamping component 12 can be inserted into the bag opening and closing fixture 11. When the lead screw drive assembly 14 drives the side bag conveying component 15 away from the sealing component 16, the bag opening adjustment clamping component 12 can separate the inner and outer films of the film bag and move the film bag to a preset length, ensuring that the film bag opening is neatly formed, laying the foundation for the subsequent precise clamping of the formed film bag by the pull strap mechanism 3.

[0036] Based on the above embodiments, the strap mechanism 3 includes a bag transport bracket 31; a belt drive assembly 32 is rotatably mounted on the bag transport bracket 31, and a lifting seat 33 is movably mounted on the bag transport bracket 31. The belt drive assembly 32 can drive the lifting seat 33 to move back and forth, achieving rapid horizontal transfer; a screw lifting assembly 34 is provided on one side of the lifting seat 33, and a clamping arm beam 35 is movably mounted on the other side; the screw lifting assembly 34 can drive the clamping arm beam 35 to move back and forth, achieving precise vertical lifting; a screw drive assembly 36 is provided on the clamping arm beam 35; a first bag opening clamping assembly 37 and a second bag opening clamping assembly 38 are movably mounted on the clamping arm beam 35; the screw drive assembly 36 can drive the first bag opening clamping assembly 37 and the second bag opening clamping assembly 38 to move closer to or further away from each other.

[0037] Based on the above embodiments, the first bag opening clamping assembly 37 and the second bag opening clamping assembly 38 are mirror images of each other to ensure clamping symmetry; the first bag opening clamping assembly 37 includes a first bag opening clamping seat 371 slidably disposed on the clamping arm beam 35; the first bag opening clamping seat 371 is detachably mounted with a first bag opening clamping cylinder 372 for easy maintenance and replacement; an L-shaped clamping arm 373 is mounted on the output end of the first bag opening clamping cylinder 372; the L-shaped clamping arm 373 has an extension portion 3 mirror images of each other along its side. 731, 3732, the ends of the extensions 3731 and 3732 are rounded to avoid scratching the film bag; an insert plate 374 is provided between the extensions 3731 and 3732, the end of the insert plate 374 is rounded to help open the bag opening and support the film bag; wherein: the first bag opening clamping cylinder 372 can drive the extensions 3731 and 3732 to move closer or further away from each other towards the insert plate 374, so as to achieve stable clamping or releasing of the formed film bag, which facilitates the transfer or exchange of the formed film bag.

[0038] Based on the above embodiments, the rotation switching mechanism 2 includes a rotation mechanism 21, a servo drive source 22, and clamping components 23; the rotation mechanism 21 includes a rotatably mounted S-bracket 211; the S-bracket 211 is driven by a first servo motor 212 to rotate back and forth, with a 180° rotation time of ≤0.5 seconds, significantly shortening the switching time; the servo drive source 22 is rotatably mounted on one side of the S-bracket 211 to provide power; there are two clamping components 23, which are centrally symmetrical and movably mounted on one side of the S-bracket 211; the clamping components 23 are movably provided with clamping parts 231 that move closer to or further away from each other. 232, the servo drive source 22 can drive the clamping parts 231 and 232 on the clamping component 23 to move closer or further apart to facilitate adjustment of the clamping position of the film bag; wherein: after the clamping component 23 clamps the opening of the formed film bag transferred from the pull belt mechanism 3, when the first drive servo motor 212 completes the 180° rotation of the S bracket 211, the film bag is rotated to the packaging box insertion position (not shown) to prepare for the packaging box insertion. At this time, another clamping component 23 is ready to clamp the formed film bag transferred from the pull belt mechanism 3, which shortens the supply cycle of the formed film bag and improves the film coating efficiency of the packaging box.

[0039] Based on the above embodiments, a guide slide 4 is provided between the film bag forming mechanism 1 and the rotation switching mechanism 2; a carrying platform 41 is provided on the guide slide 4 for temporarily carrying the film bag to be transferred; arc-shaped sliding parts 42 are symmetrically extended downward on both sides of the carrying platform 41; a protective part 43 is provided directly opposite the arc-shaped sliding part 42, and adjacent protective parts 43 and arc-shaped sliding parts 42 form an arc-shaped channel to prevent the film bag from shifting during the transfer process and improve the transfer stability.

[0040] The working process of this utility model is as follows: Start the film bag forming mechanism 1, the screw drive assembly 14 drives the side bag pulling component 15 to move closer to the sealing component 16, the bag opening adjustment clamping component 12 is inserted into the bag opening opening and closing fixture 11, the screw drive assembly 14 then drives the side bag pulling component 15 to start moving away from the sealing component 16, at this time the bag opening adjustment clamping component 12 pulls the film bag (raw material) located at the bag opening opening and closing fixture 11 to the preset length, and the cutter (not shown) of the sealing component 16 completes the heat sealing forming of the film bag. Simultaneously, the belt pulling mechanism 3 is activated, the belt drive assembly 32 drives the lifting seat 33 to move above the film bag forming mechanism 1, the screw lifting assembly 34 drives the clamping arm beam 35 to descend, and the screw drive assembly 36 drives the first bag mouth clamping assembly 37 and the second bag mouth clamping assembly 38 to move closer together. The extensions 3731 and 3732 of the L-shaped clamping arms 373 move towards the insert plate 374 under the drive of the first bag mouth clamping cylinder 372 and clamp the formed film bag mouth. The insert plate 374 assists in opening the bag mouth and provides support for the film bag. Subsequently, the screw lifting assembly 34 drives the clamping arm beam 35 to rise, and the belt drive assembly 32 drives the lifting seat 33 to move towards the rotary switching mechanism 2, so that the film bag is put into the clamping parts 231 and 232 of the clamping component 23. The transfer process is short. After the clamping parts 231 and 232 of the clamping component 23 clamp the opening of the film bag, the first servo motor 212 drives the S-bracket 211 to rotate 180°, rotating the film bag to the packaging box insertion position (not shown), preparing for the packaging box to be inserted. At this time, another clamping component 23 prepares to clamp the formed film bag transferred from the pull-belt mechanism 3. During the rotation of the S-bracket 211 driven by the first servo motor 212, the pull-belt mechanism 3 reverses its action, the belt drive assembly 32 drives the lifting seat 33 to reset, and the screw lifting assembly 34 drives the clamping arm beam 35 to descend, preparing for the next cycle. This greatly shortens the supply cycle of the formed film bag and improves the film coating efficiency of the packaging box. Through the above design, the total time consumed in a single cycle of this device is shortened, and the efficiency is significantly improved compared with traditional devices.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art should be able to make equivalent embodiments by making some changes or modifications to the above-disclosed technical content without departing from the scope of the present invention. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
