Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to the field of flower packaging equipment technology, specifically a flower packaging stem-tying device. Background Technology

[0002] Currently, flower packaging almost entirely relies on manual labor. Flowers are stacked into specific shapes, wrapped in corrugated kraft paper, and then the stems are cut and tied. This manual method is not only time-consuming and labor-intensive but also demands a high level of skill from the operators. Furthermore, manual stem tying is inefficient and cannot guarantee consistent quality. Therefore, there is an urgent need for equipment that can automatically tie flower stems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a flower packaging stem-tying device, which solves the problems of low efficiency and poor consistency of traditional manual tying and has significant industrial application value.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a flower packaging stem-tying device, including a frame, a binding base plate installed on the frame, and a glue-pulling strip assembly, a pressure nail assembly and a glue strip assembly provided above the binding base plate, with the glue-pulling strip assembly and the glue strip assembly located on both sides of the pressure nail assembly.

[0005] The adhesive strip assembly is provided with an adhesive strip pre-tightening assembly, an adhesive strip tensioning assembly, and an adhesive strip front clamping assembly in sequence along the adhesive strip travel path. An adhesive strip receiving assembly is provided on the outside of the adhesive strip receiving assembly, and an adhesive strip shrinking assembly is provided on the outside of the adhesive strip receiving assembly to facilitate the pressing of the pin. An adhesive strip cutter assembly for cutting the adhesive strip is provided at the pressing point of the pressing assembly.

[0006] By integrating the functions of adhesive strip tensioning and nailing, the process of bundling and cutting flower stems is automated, improving packaging efficiency. The segmented control of the adhesive strip assembly (pre-tightening, tensioning, and front clamping) ensures uniform tension of the adhesive strip, preventing loosening or breakage.

[0007] Furthermore, the adhesive strip front clamping assembly includes an adhesive strip front clamping claw, which is driven to open and close by a first clamping cylinder. The adhesive strip front clamping claw is correspondingly positioned at the nailing point of the nailing assembly. The first clamping cylinder drives the claw to achieve rapid opening and closing, accurately positioning the adhesive strip to the nailing position, ensuring a secure binding.

[0008] Furthermore, the pre-tightening assembly for the rubber strip includes a pre-tightening cylinder, a sliding plate connected to the cylinder's push rod, and pre-tightening claws mounted on the sliding plate. The pre-tightening claws are driven to open and close by a second clamping cylinder. The pre-tightening cylinder and the pre-tightening claws work together to pre-eliminate slack in the rubber strip, preventing slippage or deformation during subsequent tightening.

[0009] Furthermore, the adhesive strip tensioning assembly includes a tensioning cylinder, a sliding plate connected to the cylinder's push rod, and tensioning claws mounted on the sliding plate. The tensioning claws are driven to open and close by a third clamping cylinder. The tensioning cylinder provides stable tension, which, combined with the tensioning claws, ensures the adhesive strip is taut and secure after binding.

[0010] Furthermore, the adhesive strip assembly includes adhesive strip receiving claws, which are opened and closed by an adhesive strip receiving cylinder. The adhesive strip receiving claws receive the end of the adhesive strip, facilitating the next binding cycle and reducing manual intervention.

[0011] Furthermore, the adhesive strip shrinking assembly includes a shrinking rod and an adhesive strip shrinking cylinder, with the top rod of the adhesive strip shrinking cylinder connected to the shrinking rod.

[0012] Furthermore, the nail-pressing assembly includes a nail-pressing seat, a nail-pressing guide post and a nail-pressing rod at the nail-pressing point of the nail-pressing seat, and the nail-pressing rod is driven by a nail-pressing cylinder; the nail-pressing guide post is equipped with a nail-pressing sensor for detecting material shortage, and the nail-pressing guide post is also equipped with a nail retraction cylinder. The nail-pressing guide post and nail-pressing sensor ensure accurate nail positioning, automatically trigger an alarm when material is insufficient, and reduce the scrap rate.

[0013] Furthermore, the adhesive strip assembly includes an adhesive strip swing arm, one end of which is provided with an adhesive strip claw, and the other end of which is connected to an adhesive strip swing arm cylinder. A fourth clamping cylinder is mounted on the adhesive strip swing arm to drive the adhesive strip claw to open and close.

[0014] Furthermore, this flower packaging stem-tying device also includes a stem-holding component, which consists of a left stem-holding claw and a right stem-holding claw. The left and right stem-holding claws together encircle and hold the flower stem. The stem-holding component is located on one side of the pressure-pin component and is on the same side as the adhesive strip component. The left and right stem-holding claws fix the flower stem, preventing the bouquet from shifting when cutting the stem and ensuring a clean cut. Its placement on the same side as the adhesive strip component optimizes space utilization.

[0015] The beneficial effects of this utility model are: This utility model has a simple structure and the following advantages:

[0016] (1) Fully automated integration, with bundled and nailed design, significantly improves flower packaging efficiency and reduces labor costs;

[0017] (2) Precise control, with each cylinder and sensor working together to ensure the rubber strip is taut and the nail is firmly pressed;

[0018] (3) High reliability, with designs such as material shortage detection and segmented management of adhesive strips reducing the failure rate, making it suitable for large-scale production. Attached Figure Description

[0030] like Figures 1-6 The illustrated flower packaging stem-tying device includes a frame (not shown in the figure), on which a binding base plate is mounted. Above the binding base plate are a tape-pulling assembly, a pinning assembly, and a tape assembly, with the tape-pulling assembly and the tape assembly located on either side of the pinning assembly. Along the tape travel path, the tape assembly is provided with a tape pre-tightening assembly, a tape tensioning assembly, and a tape front clamping assembly. A tape receiving assembly is located outside the tape front clamping assembly, and a tape shrinking assembly for facilitating pinning is located outside the tape receiving assembly. A tape cutter assembly for cutting the tape is located at the pinning point of the pinning assembly.

[0031] The adhesive strip front clamping assembly includes an adhesive strip front clamping claw 7, which is driven to open and close by a first clamping cylinder 8. The adhesive strip front clamping claw 7 is correspondingly set at the pressing point of the pressing nail assembly.

[0032] The rubber strip pre-tightening assembly includes a pre-tightening cylinder 4, the top rod of the pre-tightening cylinder 4 is connected to a slide plate, and a pre-tightening claw 9 is installed on the slide plate. The pre-tightening claw 9 is driven to open and close by a second clamping cylinder 3.

[0033] The rubber strip tensioning assembly includes a tensioning cylinder 10, a sliding plate connected to the top rod of the tensioning cylinder 10, and a tensioning claw 11 installed on the sliding plate. The tensioning claw 11 is driven to open and close by a third clamping cylinder 12.

[0034] The adhesive strip assembly includes an adhesive strip clamp 13, which is driven to open and close by an adhesive strip cylinder 6.

[0035] The rubber strip shrinking assembly includes a shrinking rod 14 and a rubber strip shrinking cylinder 2, with the push rod of the rubber strip shrinking cylinder 2 connected to the shrinking rod 14.

[0036] The nail clamping assembly includes a nail clamping seat 15, with a nail clamping guide post 16 and a nail clamping rod 17 at the nail clamping point. The nail clamping rod 17 is driven by a nail clamping cylinder 1. The nail clamping guide post 16 is equipped with a nail clamping sensor for detecting insufficient material, and a nail retraction cylinder 5 is also installed on the nail clamping guide post 16. A nail retraction block is installed at the push rod of the nail retraction cylinder 5, located outside the nail clamping guide post 16. When the push rod of the nail retraction cylinder 5 extends, the nail retraction block abuts against the nail adhesive on the nail clamping guide post 16, and drives the nail adhesive to retract along the nail clamping guide post 16.

[0037] The adhesive strip assembly includes an adhesive strip swing arm, one end of which is provided with an adhesive strip claw 20, and the other end of which is connected to an adhesive strip swing arm cylinder 22. A fourth clamping cylinder 21 is mounted on the adhesive strip swing arm to drive the adhesive strip claw 20 to open and close.

[0038] This flower packaging stem-tying device also includes a stem-holding component, which includes a left stem-holding claw 18 and a right stem-holding claw 19. The left stem-holding claw 18 and the right stem-holding claw 19 together encircle and hold the flower stem. The stem-holding component is located on one side of the pressure nail component, and the stem-holding component and the adhesive strip component are located on the same side.

[0039] The working process of this flower wrapping stem-tying device is as follows:

[0040] In the initial state, the left gripping claw 18 and the right gripping claw 19 open to the sides, and the adhesive strip passes through the pre-tightening claw 9 and the tensioning claw 11 in sequence, and is finally clamped by the front clamping claw 7 of the adhesive strip.

[0041] During operation, the stem-cutting lifting assembly raises the flower packaging stem-tying device to the required stem-cutting height. The adhesive strip clamping claw 20 clamps the adhesive strip in front of the adhesive strip clamping claw 7. The adhesive strip clamping claw 7 is released, and the pre-tightening claw 9 and the tensioning claw 11 are released simultaneously. Then, the adhesive strip swing arm cylinder 22 works, and the adhesive strip clamping claw 20 rotates outward to pull the adhesive strip.

[0042] When the flowers are transported by the flower carrier, the left stem-holding claw 18 and the right stem-holding claw 19 close together to hold the flower stem. The rubber strip clamping claw 20 carries the rubber strip around the flower stem and then sends the rubber strip to the receiving rubber strip clamping claw 13. The receiving rubber strip clamping claw 13 clamps the rubber strip, and the rubber strip clamping claw 20 releases and retracts. At the same time, the pre-tightening claw 9 clamps the rubber strip, and the push rod of the pre-tightening cylinder 4 extends to give the rubber strip a certain tension.

[0043] Next, the tape retraction cylinder 2 drives the retraction rod 14 forward, which in turn moves the tape to the pressure nail. The tape clamping claw 13 keeps the tape tightly clamped. Simultaneously, the tensioning claw 11 tightens the tape, and the tensioning cylinder 10 retracts its push rod, further tightening the tape. Then, the tape front clamping claw 7 clamps the tape, and the pressure nail cylinder 1 drives the pressure nail rod 17 downward, binding the tape at both the retraction rod 14 and the tape front clamping claw 7 with the tape. The tape cutter 23 then cuts the tape at the tape front clamping claw 7, and the tape clamping claw 13 releases the tape, completing the flower stem binding operation. The tape front clamping claw 7 clamps the tape, facilitating the next binding cycle.

[0044] The above description is only a specific embodiment of the present utility model. Various examples and illustrations do not constitute a limitation on the substantive content of the present utility model. Those skilled in the art can make modifications or variations to the above-described specific embodiments after reading the description without departing from the essence and scope of the utility model.
