Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a coding component for a flat-push vacuum packaging machine. Background Technology

[0002] In the packaging of food and other materials, vacuum packaging machines require loading materials into blister packs and covering them with blister caps. Then, a coding head prints information such as the production date on the blister cap. Existing coding machines typically use ribbon coding machines, where the coding head is mounted on a fixed frame, and the labeling rolls required for coding must be attached to the blister cap via a coding platform. However, ribbon coding machines require frequent ribbon replacements, and the coding head needs regular maintenance due to long-term use. The disassembly and assembly process of traditional coding heads is complex, requiring tools to remove each fixing bolt, which is time-consuming and labor-intensive, severely impacting production progress.

[0003] Therefore, there is an urgent need for a coding component that is easy to assemble, disassemble, and maintain quickly in order to improve the operating efficiency of vacuum packaging lines. Utility Model Content

[0004] This utility model aims to solve the technical problems of cumbersome disassembly and assembly and low maintenance efficiency of coding machine heads in the prior art, and provides a coding component for vacuum packaging machines with simple structure and convenient operation. The quick-release structure enables rapid installation and disassembly of the coding machine head, reducing maintenance time and ensuring production continuity.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A coding component for a flat-push vacuum packaging machine includes a mounting frame. The mounting frame is equipped with a feeding roller, an output guide roller, a coding platform, and a horizontally movable coding head. The coding head is mounted on a slider of an XY bidirectional motion module. The slider has a mounting frame with an insertion slot at its lower end. The upper end of the coding head has an insertion block that mates with the insertion slot. A quick-release structure is provided between the insertion block and the insertion slot. The quick-release structure includes a guide hole on the side wall of the insertion slot, a stop block within the guide hole, a sealing plate mounted on the outer end of the guide hole, a compression spring connecting the sealing plate and the stop block, a slot on the side wall of the insertion block, a transmission rod connected to the stop block, a rotatable cam with one end of the transmission rod extending through the sealing plate and connected thereto, and a handle on the outer wall of the cam. Rotating the handle drives the stop block to extend and retract along the guide hole, and the stop block engages with the slot under the action of the spring.

[0007] The cross-section of the anti-retraction block is a right-angled triangle, with the inclined surface of the right-angled triangle facing the direction of the insertion block.

[0008] The cam is always in contact with the sealing plate under the elastic action of the compression spring, and the side wall of the cam is provided with a positioning flat surface; when the positioning flat surface contacts the sealing plate, the anti-retraction block retracts into the guide hole and can prevent the cam from rotating.

[0009] When installing the coding head, rotate the cam by turning the handle to disengage the positioning flat surface from the sealing plate. After the insert block is inserted into the insertion slot, the anti-reverse block is locked into the slot to complete the fixation.

[0010] The beneficial effects of this utility model are as follows: This utility model achieves flexible positioning of the coding head through an XY bidirectional motion module. Combined with the quick-release structure of the insert block-insertion slot and the cam-driven anti-reverse block extension mechanism, it significantly simplifies the disassembly and assembly process of the coding head. Maintenance requires no tools; disassembly can be completed simply by turning the handle. The time for ribbon replacement or head maintenance is reduced by more than 80%, while ensuring the stability after installation, effectively improving the production efficiency and ease of operation of the vacuum packaging line.

Detailed Implementation

[0017] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0018] like Figure 1 — Figure 4As shown, this embodiment discloses a coding component for a flat-push vacuum packaging machine. The coding component includes a mounting frame 101, on which a feeding roller 102, an output guide roller 103, a coding platform 104, and a coding head 105 are mounted. Labeling rolls are sleeved on the feeding roller 102. After being unwound, the rolls pass through the coding platform 104 and are then output by the output guide roller 103. The coding head 105 is located above the coding platform 104 and can move horizontally. It is mounted via a slider 107 of an XY bidirectional motion module 106, enabling free horizontal movement. A frame 108 is fixedly mounted on the slider 107. An insertion slot 109 is provided at the bottom of the mounting frame 108, and an insertion block 110 that mates with the insertion slot 109 is provided at the upper end of the coding head 105.

[0019] A quick-release structure is provided between the insert block 110 and the insertion slot 109. This quick-release structure includes: a guide hole 111 on the side wall of the insertion slot 109; a stop block 112 inside the guide hole 111; a sealing plate 113 installed at the outer end of the guide hole 111; and a compression spring 114 connecting the sealing plate 113 and the stop block 112. A slot 115 is formed on the side wall of the insert block 110, and the stop block 112 is engaged in the slot 115 under the action of the spring 114. A transmission rod 116 is connected to the stop block 112. One end of the transmission rod 116 passes through a hole in the sealing plate 113 and is connected to a rotatable cam 117. A handle 118 is provided on the outer wall of the cam 117. The stop block 112 has a right-angled triangular cross-section, with the inclined surface facing the insert block 110.

[0020] The cam 117 remains in contact with the sealing plate 113 under the elastic action of the compression spring 114, and its side wall is provided with a positioning flat surface 119. When the handle 118 rotates the cam 117 to make the positioning flat surface 119 contact the sealing plate 113, the anti-reverse block 112 retracts into the guide hole 111, which prevents the cam 117 from continuing to rotate, making it easier to pull out the coding head 105 for disassembly. During installation, first rotate the cam 117 180° using the handle 118 to disengage the positioning flat surface 119 from the sealing plate 113, and then insert the insertion block 110 of the coding head 105 into the insertion slot 109. The anti-reverse block 112, under the action of the spring 114, locks into the slot 115 of the insertion block 110, thus completing the installation.

[0021] Quick-release structure operation procedure:

[0022] Disassembly process: Hold the handle and rotate the cam 180° clockwise until the flat surface fits against the sealing plate. The anti-retracting block will retract completely into the guide hole. Pull the coding head upward to separate the insert block from the insertion slot.

[0023] Installation process: Align the insert of the coding head with the insertion slot, turn the handle counterclockwise 180° to make the inclined surface of the cam push the anti-retracting block back, continue to press down the coding head until the insert is fully inserted, then release the handle to make the anti-retracting block lock into the slot under the action of the spring force, thus completing the locking.

[0024] This structure enables quick assembly and disassembly of the coding head 105, allowing maintenance to be completed without tools, significantly reducing downtime and improving the continuous production capacity of the vacuum packaging machine.
