Description

Technical Field

[0001] This utility model relates to the field of packaging paper slitting technology, and in particular to a food packaging paper slitting device. Background Technology

[0002] Food packaging paper plays an important role in the modern food industry. Its slitting technology is a key link in the production process. The main purpose of the slitting process is to cut large rolls of packaging paper into sizes and specifications that meet customer needs in order to satisfy different food packaging requirements.

[0003] While existing food packaging paper slitting equipment can complete basic slitting tasks, excess material is generated on both sides of the packaging paper when it is slitting to a specific size. Since food packaging paper usually has a smooth surface, the excess material after slitting is easily sealed in a vacuum with the packaging paper when they are in close contact, making it difficult to separate. This causes the excess material after slitting to easily stick to the packaging paper, which not only affects the winding quality of the packaging paper but also increases the difficulty of manual cleaning. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a food packaging paper cutting device, which has the advantages of automatically separating the leftover material after cutting and facilitating the collection of the leftover material.

[0005] This utility model provides a food packaging paper slitting device, including a processing table. A slitting mechanism is provided on the top of the processing table. Two upright plates are symmetrically arranged front and back on the top of the processing table. A servo motor is provided on the side wall of the front upright plate. A take-up roller is connected to the output shaft of the servo motor. Two separators for separating excess material are sleeved on the take-up roller. A separator strip is provided on the side of the separators near the slitting mechanism. An adjustment component for adjusting the spacing between the two separators is provided on the top of the upright plate.

[0006] Preferably, the slitting mechanism includes a slitting frame, which is fixed to the top of the processing table. A drive motor is provided on the side wall of the slitting frame.

[0007] Preferably, the top of the processing table has a feeding port located below the winding roller, and a support plate is fixedly connected to the side of the upright plate near the slitting mechanism, with a support roller rotatably connected between the two support plates.

[0008] By adopting the above technical solution, a convenient unloading channel is provided for the leftover material after slitting by setting up a feeding port, which avoids the accumulation of leftover material on the processing table and improves the continuity of the production process.

[0009] Preferably, the adjustment assembly includes a mounting bracket disposed on the top of the vertical plate. The mounting bracket includes a horizontal plate and two vertical plates disposed on the horizontal plate. A bidirectional threaded rod is rotatably connected between the two vertical plates. Sliding blocks are threadedly connected to both sides of the outer side of the bidirectional threaded rod. A guide rod is fixedly connected to the bottom of the sliding blocks.

[0010] By adopting the above technical solution, the distance between the two dividing discs can be adjusted according to the width of the slit packaging paper by setting the adjustment component, so that the slit packaging paper can be wound on the winding roller, and the dividing strips on the dividing discs can separate the excess material on both sides of the packaging paper, thus facilitating the collection of the excess material after slitting.

[0011] Preferably, the inside of the horizontal plate is provided with a guide groove, and the bottom of the guide rod passes through the guide groove and is fixedly connected to the separator plate.

[0012] Preferably, a collection box is placed below the processing table, and the collection box corresponds to the position of the discharge port.

[0013] Preferably, the separator has triangular cross-sections at both ends, and the end of the take-up roller away from the servo motor is rotatably connected to the rear upright plate via a bearing.

[0014] By adopting the above technical solution, the triangular cross-section separator strip can better separate the leftover material during the winding process, preventing the leftover material and the packaging paper from rubbing against each other or sticking together.

[0015] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: by setting a winding roller and sleeve a separator plate on the winding roller, the winding roller can automatically separate the leftover material after slitting during the winding and slitting of the packaging paper, avoiding the leftover material from sticking to the packaging paper, and transporting the leftover material to the collection box for collection, reducing manual operation.

[0024] like Figure 1-4 As shown, the present invention proposes a food packaging paper slitting device, including a processing table 1. The top of the processing table 1 is provided with a slitting mechanism. The top of the processing table 1 is provided with two upright plates 6 arranged symmetrically front to back. A servo motor 7 is provided on the side wall of the front upright plate 6. A take-up roller 8 is connected to the output shaft of the servo motor 7. Two separators 15 for separating the excess material are sleeved on the take-up roller 8. A separator strip 16 is provided on the side of the separator 15 near the slitting mechanism. The top of the upright plate 6 is provided with an adjustment component for adjusting the spacing between the two separators 15.

[0025] Please see Figure 1 In this embodiment, the slitting mechanism includes a slitting frame 2, which is fixed on the top of the processing table 1. A drive motor 3 is provided on the side wall of the slitting frame 2. A shaft is connected to the output shaft of the drive motor 3. The other end of the shaft is rotatably connected to the inner wall of the slitting frame 2. Two cutters 4 are provided on the outside of the shaft. A paper guide roller 5 is provided on the inner side wall of the slitting frame 2.

[0026] The slitting frame 2 has a control panel on the side away from the drive motor 3, and both the drive motor 3 and the servo motor 7 are electrically connected to the control panel.

[0027] By setting up a take-up roller 8 and mounting a separator plate 15 on the take-up roller 8, the take-up roller 8 can automatically separate the leftover material after slitting when taking up the slit packaging paper, thus preventing the leftover material from sticking to the packaging paper and making it easier to collect the leftover material, reducing manual operation. Furthermore, the adjustable component allows for easy adjustment of the distance between the two separator plates 15 according to the width of the slit packaging paper, improving applicability.

[0028] Please see Figure 1 , Figure 3 In this embodiment, the top of the processing table 1 is provided with a feeding port 12 located below the winding roller 8. The side of the upright plate 6 near the slitting mechanism is fixedly connected to a support plate 19. A support roller 18 is rotatably connected between the two support plates 19. A collection box 11 is placed below the processing table 1, and the position of the collection box 11 corresponds to that of the feeding port 12.

[0029] Among them, the support roller 18 provides support for the remaining material after slitting, and the discharge port 12 provides a convenient discharge channel for the remaining material after slitting, avoiding the accumulation of the remaining material on the processing table 1 and improving the continuity of the production process.

[0030] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment, the adjustment component includes a mounting bracket 9 disposed on the top of the vertical plate 6. The mounting bracket 9 includes a horizontal plate and two vertical plates disposed on the horizontal plate. A bidirectional threaded rod 10 is rotatably connected between the two vertical plates. One end of the bidirectional threaded rod 10 passes through the vertical plate and is fixedly connected to a handwheel 17. The threads on both sides of the bidirectional threaded rod 10 are in opposite directions. Sliding blocks 13 are threadedly connected to both sides of the outer side of the bidirectional threaded rod 10. A guide rod 14 is fixedly connected to the bottom of the sliding block 13. A guide groove 91 is opened inside the horizontal plate. The bottom of the guide rod 14 passes through the guide groove 91 and is fixedly connected to the partition plate 15.

[0031] It should be noted that by setting the adjustment component, the distance between the two separators 15 can be adjusted according to the width of the slit packaging paper. By rotating the handwheel 17 clockwise or counterclockwise to drive the bidirectional threaded rod 10 to rotate, the two sliding blocks 13 can move relative to each other or in opposite directions, thereby driving the two separators 15 to slide on the winding roller 8, so that the slit packaging paper can be wound on the winding roller 8, and the separator strips 16 on the separators 15 separate the excess material on both sides of the packaging paper, thus facilitating the collection of the excess material after slitting.

[0032] In this embodiment, the separator 16 has triangular cross-sections at both ends, and the end of the take-up roller 8 away from the servo motor 7 is rotatably connected to the rear upright plate 6 through a bearing.

[0033] It should be noted that the pointed end of the separator 16 faces the slitting frame 2, and the triangular cross-section of the separator 16 can better separate the leftover material during the winding process, preventing the leftover material and the packaging paper from rubbing against each other or sticking together.

[0034] Working principle: After the packaging paper is cut into specific sizes by the slitting mechanism, it is conveyed out and wound onto the take-up roller 8. The excess material on both sides of the packaging paper after slitting passes over the support roller 18. The servo motor 7 is started to drive the take-up roller 8 to rotate, thereby winding up the slitting packaging paper. During the winding process, the separator 16 separates the slitting excess material from the packaging paper to prevent the excess material from sticking to the packaging paper. The slitting excess material is supported by the support roller 18 and falls from the feed port 12. Therefore, the excess material directly enters the collection box 11 through the feed port 12, which avoids the excess material from accumulating on the processing table 1, facilitates the collection of excess material, and improves the continuity of the production process.

[0035] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
