Description

Technical Field

[0001] The invention belongs to the technical field of cigarette production and detection, and in particular relates to an upper cutter pressing frame type rolling and cutting device. Background Art

[0002] In its early days, cigarette wrapping paper was primarily designed to protect cigarettes and facilitate transportation. Over a long period of evolution, packaging styles across different eras, fields, and styles have each developed their own unique cultural heritage. Today's cigarette packaging not only incorporates philosophy, sociology, psychology, linguistics, and history, but also reflects knowledge of local customs and even integrates social and cultural connotations, enriching the development of regional cultures and ensuring the preservation of historical and cultural heritage.

[0003] To prevent cigarette boxes from being too soft and affecting user experience, the softness of cigarette paper must be tested during the cigarette paper production process. This test involves first cutting a sample from the unfolded area of ​​the paper, and then subjecting the sample to a pressure test. However, the pressure of the cutter during cutting leaves an upward indentation on the edge of the sample, increasing the sample's bending resistance and affecting the test results. Therefore, the compression test requires pre-treatment of the sample paper to smooth its edges, a cumbersome process. Summary of the Invention

[0004] Based on the problems mentioned in the above background technology, the present invention provides an upper cutter pressure frame type rolling and cutting device, which is used to solve the problem that when cutting the packaging paper, the pressure of the knife leaves an upward indentation on the edge of the packaging paper sample, resulting in an increase in the bending resistance of the sample cigarette paper, affecting the test results. At the same time, the existing device has a major safety hazard.

[0005] The technical solution adopted in the present invention is as follows:

[0006] The cam is provided with a plurality of cams and a plurality of cams, and the cams are provided with a plurality of cams and a plurality of cams, and the cams are provided with a plurality of cams and a plurality of cams, and the cams are provided with a plurality of cams and a plurality of cams. The inner wall of the annular cutter fits the groove wall of the second knife groove, and a push rod is installed on the annular knife seat, and the push rod is passed through the pressure plate, and a contact is installed on the top of the push rod, and a second spring is installed between the contact and the pressure plate, and the second spring is sleeved on the push rod, and an ear plate corresponding to the position of the contact is installed on the pressure rod, and a mounting cylinder is installed on the hinged frame, and blind holes are provided at both ends of the mounting cylinder, and a connecting hole is provided between the two blind holes, and a rotating shaft is passed through the connecting hole, and a torsion spring is sleeved on the rotating shaft, and both ends of the torsion spring are fixedly connected to the rotating shaft and the mounting cylinder respectively, and roller frames are fixedly installed at both ends of the rotating shaft, and a pressure roller is installed between the two roller frames.

[0007] On the basis of the above scheme, the present invention also makes the following improvements:

[0008] Furthermore, the outer wall of the pressing roller is coated with a rubber layer, which enables the pressing roller to be in flexible contact with the die table, so that the pressing roller can better roll the cigarette paper.

[0009] Furthermore, a compensation frame is slidably mounted within the first knife groove, comprising a frame corresponding to the first knife groove, a first supporting column and a second supporting column mounted on the frame, a pressure strip mounted on the hinged frame, the first supporting column corresponding to the pressure strip, and the second supporting column corresponding to the pressure rod, with a third spring mounted at the bottom end of the frame. The compensation frame automatically rises after the pressure plate rises, sealing the open end of the first knife groove, thereby preventing the edge of the cut cigarette paper from hanging in the air, which would otherwise make rolling and smoothing the paper difficult.

[0010] Furthermore, a limiting post is integrally formed at the bottom end of the compensation frame, a through hole matching the limiting post is formed at the bottom end of the first knife groove, the limiting post is inserted into the through hole, and the third spring is sleeved on the limiting post. The limiting post guides the movement of the compensation frame to prevent the compensation frame from deflecting during movement.

[0011] Furthermore, there are two push rods, and the push rods are located in the middle of the annular knife seat. The push rods are located in the middle of the annular knife seat to avoid stress concentration at the connection part between the push rods and the annular knife seat.

[0012] Furthermore, a limiting frame corresponding to the hinge frame is installed on the placement table. The limiting frame can limit the transition rotation of the first hinge frame, so that the pressing plate can be kept in an inclined state under the limiting effect of the limiting frame after being lifted, thereby preventing the pressing plate from falling backward and facilitating use.

[0013] Furthermore, a handle is provided at the bottom end of the pressure rod, which facilitates the rotation of the pressure rod and is convenient for use.

[0014] Beneficial effects of the present invention:

[0015] 1. The blade of the annular cutter is coplanar with the inner wall of the annular cutter, and the inner wall of the annular cutter is in contact with the wall of the second knife groove. This can reduce the gap between the blade area of ​​the annular cutter and the wall of the second knife groove during cutting, making the cut of the paper more neat, avoiding the edge of the paper from warping up significantly after cutting, which increases the anti-bending ability of the paper and reduces the impact on the test results.

[0016] 2. The roller frame is installed on the rotating shaft, and the rotating shaft and the mounting cylinder are connected by a torsion spring. When the pressure plate rotates under the cover, the pressure roller on the roller frame can maintain contact with the placement table. Since the rotating shaft itself can rotate, when the pressure plate is under the cover, the roller frame rotates with it, causing the pressure roller to roll on the placement table. When the pressure plate returns to its original position, the roller shaft follows it and can automatically roll the cut cigarette paper sample to smooth the edge of the sample paper, avoiding the edge of the sample paper from warping due to cutting and squeezing, which affects the test results. It is convenient to use and does not require manual movement of the cigarette paper after cutting.

[0017] 3. After the pressure plate is lifted, the circular cutter will automatically retract into the second cutter groove under the action of the second spring. The staff will not come into contact with the circular cutter when placing or taking out paper, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS

The push rod 33 is passed through the pressure plate 2, and a contact 34 is installed on the top of the push rod 33. A second spring 35 is installed between the contact 34 and the pressure plate 2, and the second spring 35 is sleeved on the push rod 33. An ear plate 26 corresponding to the position of the contact 34 is installed on the pressure rod 24, and a mounting cylinder 27 is installed on the hinged frame 22. Blind holes 271 are provided at both ends of the mounting cylinder 27, and a connecting hole is provided between the two blind holes 271. A rotating shaft 28 is passed through the connecting hole, and a torsion spring 272 is sleeved on the rotating shaft 28. The two ends of the torsion spring 272 are fixedly connected to the rotating shaft 28 and the mounting cylinder 27 respectively. Roller frames 51 are fixedly installed at both ends of the rotating shaft 28, and a pressure roller 52 is installed between the two roller frames 51.

[0034] On the basis of the above scheme, the present invention also makes the following improvements:

[0035] Specifically, the outer wall of the pressing roller 52 is covered with a rubber layer. When rolling the cut cigarette paper, the outer wall of the pressing roller 52 is covered with the rubber layer, so that the pressing roller 52 and the die table 12 are in flexible contact, so that the pressing roller 52 can better roll the cigarette paper.

[0036] Specifically, a compensation frame 4 is slidably installed in the first knife groove 121, and the compensation frame 4 includes a frame frame 41 corresponding to the first knife groove 121, a first receiving column 421 and a second receiving column 422 are installed on the frame frame 41, and a pressure strip 221 is installed on the hinge frame 22, the first receiving column 421 corresponds to the pressure strip 221, and the second receiving column 422 corresponds to the pressure rod 24, and a third spring 44 is installed at the bottom end of the frame frame 41. After the pressure plate 2 is lifted, the compensation frame 4 rises back to its position by itself under the action of the third spring 44, and the open end of the first knife groove 121 is closed by the frame frame 41 to avoid the edge of the cut cigarette paper from being suspended in the air, which causes the two sides of the cigarette paper to be suspended and inconvenient for rolling and smoothing.

[0037] Specifically, a limiting column 43 is integrally formed at the bottom end of the compensation frame 4, and a through hole matching the limiting column 43 is opened at the bottom end of the first knife groove 121. The limiting column 43 is passed through the through hole, and the third spring 44 is sleeved on the limiting column 43. When the compensation frame 4 is raised or lowered, the movement of the compensation frame 4 is guided by the limiting column 43 to prevent the compensation frame 4 from deflecting during movement.

[0038] Specifically, there are two push rods 33 , and the push rods 33 are located in the middle of the annular blade holder 31 . The push rods are located in the middle of the annular blade holder to avoid stress concentration at the connection portion between the push rods and the annular blade holder.

[0039] Specifically, a limiting frame 15 corresponding to the hinge frame 22 is installed on the placement table 11. The limiting frame 15 can limit the transition rotation of the first hinge frame, so that the pressing plate can be kept in an inclined state under the limiting effect of the limiting frame 15 after being lifted, thereby preventing the pressing plate 2 from falling backward and facilitating use.

[0040] Specifically, a handle 241 is provided at the bottom end of the pressure rod 24, which facilitates the rotation of the pressure rod for easy use.

[0041] When using the cut paper, place the wrapping paper flat on the placement table 11, and make the non-crease area of ​​the cigarette paper correspond to the position of the mold table 12, rotate the pressing plate 2 to fit the mold table 12, during this process, the pressure strip 221 and the pressure rod 24 are respectively in contact with the top of the first receiving column 421 and the second receiving column 422, and the frame 41 is pressed down to shrink the third spring 44, and the pressure rod 24 is continued to be pressed down. Since the pressing plate 2 is in contact with the placement table 11 and cannot move further, when the pressure rod 24 is pressed down, it squeezes the contact 34 through the ear plate 26, and the second spring 35 compresses the annular knife seat 31 to drive the annular cutter 32 to descend and cut the cigarette paper (such as Figure 10 After cutting is completed, the pressing plate 2 is rotated back to its original position, and the roller frame 51 rotates accordingly to drive the pressing roller 52 to return to its original position, and the cut cigarette paper is rolled by itself to smooth the edge of the sample paper, thereby avoiding the edge of the sample paper being warped due to cutting and squeezing, which affects the test results. It is easy to use and does not require manual movement of the cigarette paper after cutting.
