[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] The following describes the tear line processing device for fresh-keeping bags according to an embodiment of the utility model in conjunction with the accompanying drawings.

[0022] The tear line processing device for fresh-keeping bags provided in the embodiment of the utility model can be used for processing tear lines. By adjusting the pressure applied, it can effectively avoid the situation where the point-breaking knife causes the fresh-keeping film to tear directly after completing the tear line processing. This not only ensures the processing quality, but also improves the processing efficiency.

[0023] like Figure 1-Figure 3 As shown, the tear line processing device for fresh-keeping bags according to the embodiment of the utility model may include a bottom box 1, a bracket 2, a pressing table 3, a pressing point-breaking mechanism 4 and a point-breaking knife 5.

[0024] As a possible situation, support rods may be installed at the four corners of the bottom end of the bottom box 1 to facilitate adjustment of the levelness of the bottom box 1 .

[0025] The bracket 2 is fixedly connected to the top four corners of the bottom box 1 .

[0026] It should be noted that feed grooves are provided on both sides of the bracket 2 described in the above embodiment.

[0027] The pressing table 3 is fixedly connected to the middle of the top end of the bottom box 1 .

[0028] It can be understood that the pressing table 3 can assist the pressing component 43 in pressing the plastic wrap.

[0029] The pressing point breaking mechanism 4 is installed at the middle of the bottom end of the bracket 2 , and the pressing point breaking mechanism 4 may include a hydraulic cylinder 41 , a pressing plate 42 , a pressing component 43 and a limiting component 44 .

[0030] It should be noted that the pressing components 43 described in the above embodiment are provided in two groups.

[0031] The hydraulic cylinder 41 is detachably mounted on the bottom end of the bracket 2 , the pressing plate 42 is fixedly connected to the protruding end of the hydraulic cylinder 41 , the pressing assembly 43 is mounted on both ends of the pressing plate 42 , and the limiting assembly 44 is connected to the bottom of the pressing assembly 43 .

[0032] Specifically, driven by the hydraulic cylinder 41, the pressing plate 42 descends accordingly, and under the action of the pressing assembly 43, the cling film is pressed to prevent the tearing line of the cling film from loosening during the processing.

[0033] The point breaking knife 5 is installed at the bottom of the pressing plate 42, and a knife hole 6 for the point breaking knife 5 to be inserted is opened through the top of the pressing platform 3.

[0034] It should be noted that, in order to facilitate the processing of the tear line of the cling film, a corresponding number of point-breaking knives 5 can be installed according to the required length.

[0035] Specifically, in the actual operation process, when processing the cling film, the relevant personnel place the bottom box 1 in the middle of the winding and unwinding machine, put the cling film into the bracket 2 through the feed slot, and place it on the pressing table 3. At the same time, the hydraulic cylinder 41 drives the pressing plate 42 to descend, and the cling film is pressed on the pressing table 3 under the action of the pressing component 43, so as to avoid the situation that the pressing component 43 presses the cling film in the air, causing the tear line to be damaged after the processing. Then, the cling film tear line is processed under the action of the point breaking knife 5, and the pressure of the pressure is adjusted to effectively avoid the situation that the point breaking knife 5 causes the cling film to tear directly after the tear line processing. Not only the processing quality is ensured, but also the processing efficiency is improved.

[0036] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the pressing assembly 43 may include a sleeve 431 , a spring 432 , an auxiliary plate 433 , a plunger 434 and a pressing wheel 435 .

[0037] It should be noted that the sleeve 431 described in the above embodiment is arranged in a T-shaped structure.

[0038] As a possible scenario, a telescopic frame is installed between the insertion rod 434 and the pressing wheel 435 .

[0039] Among them, the sleeve 431 is fixedly connected to the spring 432, the bottom end of the spring 432 is fixedly connected to the top end of the pressure plate 42, the bottom end of the sleeve 431 passes through the pressure plate 42, the two sides of the bottom end of the sleeve 431 are fixedly connected to the auxiliary plate 433, the bottom end of the sleeve 431 is slidably connected to the insertion rod 434, the pressing wheel 435 is rotatably installed at the bottom end of the insertion rod 434, and the bottom end of the sleeve 431 is provided with a socket 436 for the insertion of the insertion rod 434.

[0040] As a possible situation, in order to facilitate the extension and retraction of the insertion rod 434 in the insertion hole 436, balls can be installed on both sides of the insertion rod 434 to reduce the friction between the insertion rod 434 and the insertion hole 436.

[0041] Specifically, when the pressing plate 42 descends, the sleeve 431 descends with the pressing plate 42. When the pressing wheel 435 contacts the plastic wrap, the pressing plate 42 will continue to descend under the action of the insertion rod 434 and the insertion hole 436, and contact the auxiliary plate 433. Under the action of the auxiliary plate 433, the contact between the pressing wheel 435 and the plastic wrap is further guaranteed. At the same time, under the action of the spring 432, the pressing wheel 435 is prevented from pressing the plastic wrap with a large force, which may cause damage to the plastic wrap after the plastic wrap tearing line is processed.

[0042] In one embodiment of the present invention, Figure 1-Figure 2 As shown, the limiting assembly 44 may include an arc frame 441 and a limiting plate 442 .

[0043] As a possible situation, a rubber plate may be installed on the side of the limiting plate 442 facing the pressing wheel 435 .

[0044] The arc frame 441 is fixedly connected to the insertion rod 434 , the pressing wheel 435 is arranged at the bottom of the arc frame 441 , the limiting plate 442 is fixedly connected to the inner side of the arc frame 441 , and the limiting plate 442 is arranged toward the pressing wheel 435 .

[0045] It should be noted that under the action of the insertion rod 434 and the telescopic frame, the arc frame 441 is driven to continue to descend, and under the action of the limiting plate 442, the pressing wheel 435 is limited to prevent the pressing wheel 435 from rotating and causing the plastic wrap to slip during processing.

[0046] In one embodiment of the present invention, Figure 1-Figure 2 As shown, a material storage box 7 is slidably connected to the interior of the bottom box 1 , the knife hole 6 is connected to the bottom box 1 , and the material storage box 7 is arranged below the knife hole 6 .

[0047] It should be noted that the knife hole 6 can assist the point-breaking knife 5 to complete the processing of the tearing line of the plastic wrap pressed on the pressing table 3. At the same time, after processing, the generated waste is discharged through the knife hole 6 to the storage box 7 for unified storage, which is convenient for later cleaning.

[0048] In one embodiment of the present invention, Figure 1-Figure 2 As shown, a maintenance plate is hinged on the front surface of the bottom box 1.

[0049] It should be noted that, by providing a maintenance plate, it is convenient to take the material storage box 7 out of the bottom box 1 for cleaning.

[0050] In summary, the fresh-keeping bag tear line processing device of the embodiment of the utility model, when processing the tear line of the fresh-keeping film, completes the installation of the pressing point breaking mechanism through the bracket, and completes the fixation of the fresh-keeping film under the cooperation of the pressing component and the pressing platform. At the same time, the lower pressure plate driven by the hydraulic cylinder drives the point breaking knife to achieve the effect of processing the tear line of the fresh-keeping film. By adjusting the pressure applied, the situation in which the point breaking knife directly tears the fresh-keeping film after completing the tear line processing can be effectively avoided. This not only ensures the processing quality, but also improves the processing efficiency.
