Description

Technical Field

[0001] The utility model relates to the technical field of high-speed winding and splicing machine processing equipment, in particular to a cylinder split-type support component of a paper lifting device of a winding and splicing machine. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] The gluing device of the winder is used to complete the gluing of the tipping paper. The tipping paper passes through the gluing device, is coated with glue according to the process requirements, and then enters the post-gluing heater. A paper lifter is installed above the gluing roller. When the machine stops working, the paper lifter lifts the tipping paper away from the gluing roller to prevent the tipping paper from being glued.

[0004] like Figure 1 As shown, the paper lifting device for tipping paper mainly consists of a paper lifting roller 1, a rotating arm 2, a support 4, a pin 7, a cylinder 6, a gasket 8, a connecting rod 10, etc. One end of the cylinder 6 is installed on the back of the gluing device through the support 4, and the other end is connected to the connecting rod 10 through the pin 7. The paper lifting roller 1 is installed on the rotating arm 2 through a bracket, and the rotating arm 2 is connected to the connecting rod 10 through the pin 7. The rotating arm 2, the pin 7, the connecting rod 10, etc. form a connecting rod mechanism.

[0005] The cylinder 6 of the paper lifter 11 is a double-acting cylinder controlled by a solenoid valve. Figure 2 As shown, in the automatic mode or in the material setting mode, the cylinder 6 pulls the connecting rod 10 to lower the paper lifting roller 1, the tipping paper descends and contacts the surface of the glue roller, and the glue is smeared on the surface of the tipping paper; when the machine stops working or in the non-material setting mode, the cylinder 6 pushes the connecting rod 10 to lift the paper lifting roller 1, lift the tipping paper away from the surface of the glue roller 12, stop the gluing action, and prevent the glue from being smeared on the stationary tipping paper, causing the tipping paper to be wrapped in the glue roller assembly.

[0006] The paper lifter cylinder 6 is prone to wear and failure of the inner cavity parts due to frequent movements, or parts breakage due to uneven force, and is a consumable part that needs to be replaced. Once the cylinder 6 is damaged, the normal lifting or falling of the tipping paper cannot be guaranteed, and the tipping paper will be unevenly glued or without glue. This phenomenon will directly affect the normal progress of the subsequent process, resulting in many quality defects such as poor tipping paper wrapping, tipping paper misalignment, air leakage, and mouth drop. If not discovered in time, a large number of defective cigarettes will be produced. A large number of kraft paper sheets without glue or unevenly glued will also rotate with the paper cutting wheel to the paper cutting wheel cleaning scraper, accumulate in large quantities at the cleaning scraper, and then roll into the lower kraft paper sheet guide board, close to the drum wheel, rubbing wheel, washboard and other parts, blocking the suction hole of the drum wheel, dirtying the drum wheel and the washboard surface, resulting in cigarette transmission or washboard blockage problems, which are difficult to clean and easy to damage equipment spare parts.

[0007] Since the paper lifter cylinder 6 is installed in the gap between the back of the gluing device and the wallboard of the receiving machine, the space is narrow. In order to meet the space requirements, the pillar 4 must be disassembled when the cylinder 6 is replaced. The inventor found that there are retaining rings at the pillar 4 and the pin 7 to prevent the axial movement of the parts on the shaft. The retaining ring pliers are difficult to use in the existing space, making it difficult to remove the retaining ring and even more difficult to install, resulting in difficulty in the removal of the pillar, which makes it take a long time to replace the cylinder 6, affecting production efficiency.

[0042] As introduced in the background technology, the paper lifter cylinder in the prior art is difficult to disassemble. In order to solve the above technical problem, the utility model proposes a split support assembly of a paper lifter cylinder for a paper winding machine.

[0043] In a typical implementation of the present invention, reference is made to Figure 3As shown, a split-type pillar assembly of a cylinder of a paper lifter for a winding machine includes a first pillar 13 and a second pillar 14. The first pillar 13 is detachably connected to the end of the cylinder. The second pillar 14 is provided with a through hole. The through hole includes a first section 142 and a second section 143 connected in sequence. The size of the first section 142 is larger than that of the second section 143. A portion of the first pillar 13 is inserted into the first section of the through hole of the second pillar 14. A recess 134 is provided on the side of the first pillar 13 away from the cylinder 6. A first locking member is provided through the through hole and the recess 134 to realize the connection between the first locking member and the second pillar 14 and the first pillar 13. The second locking member passes through the original hole of the paper lifter for the winding machine to limit the end of the second pillar 14 away from the first pillar.

[0044] To facilitate installation and disassembly, the second support 14 is a sleeve, the through hole of the second support 14 is a round hole, and the first support 13 is a cylindrical structural member.

[0045] In addition, the first locking member is specifically a bolt, and the second locking member is a limit screw 3 corresponding to the tipping paper lifter. A support pad is provided at the contact point between the head of the limit screw 3 and the frame of the tipping paper lifter. After the limit screw 3 is installed, the support pad contacts the end of the second pillar 14 away from the first pillar 13.

[0046] In this embodiment, the recess of the first pillar 13 is a circular blind hole, and two sections are arranged in the circular blind hole. A threaded structure is arranged in the section in the circular blind hole for connecting with the first locking member, and a reliable connection between the first locking member and the first pillar 13 is achieved through the threaded structure. The inner side of the threaded structure in the circular blind hole is a light hole; it can be understood that the inner diameter of the recess 134 is the same as the inner diameter of the second section 143, and the depth of the recess 134 is less than the length of the first section 142 in the through hole.

[0047] refer to Figure 4 As shown, the first pillar 13 is circumferentially provided with a first stage 132 to limit the cylinder, the first stage 132 has a set width, the other section of the first pillar 13 at the first stage 132 is a cylindrical section 133, the outer diameter of the first stage 132 is larger than the outer diameters of the cylindrical section 133 and the section where the annular groove is located, the length of the cylindrical section 133 is larger than the length of the first section 142 in the through hole, one end of the cylinder 6 is sleeved on a section of the non-cylindrical section of the first pillar 13, and the first stage 132 is used to effectively limit one end of the cylinder 6.

[0048] It should be noted that an annular groove 131 is provided at a section of the first pillar 13 away from the recess 134 , and the first stage 132 is located between the annular groove 131 and the recess 134 . The annular groove 131 is used to accommodate one end of the retaining spring to prevent the axial movement of the part.

[0049] It can be understood that the outer diameter of a section of the first pillar 13 used to connect with the second pillar 14 is smaller than the inner diameter of the first section 142 in the through hole, that is, the outer diameter of the cylindrical section 133 is smaller than the inner diameter of the first section 142 in the through hole, so as to ensure that the first pillar 13 is inserted into the first section 142 of the through hole, and the end of the cylindrical section 133 of the first pillar is limited by the step between the first section 142 and the second section 143.

[0050] It can be understood that the through hole is a stepped through hole, and the through hole in the second pillar 14 also includes a third section 144 connected to the second section 143. The first section 142 is located at one end of the second section 143, and the third section 144 is located at the other end of the second section 143. The first locking member 15 is specifically a long bolt, and the screw portion of the long bolt passes through the third section 144 and the second section 143 and is connected to the recess 134 of the first pillar. The recess 134 is specifically a threaded hole. After the long bolt is tightened with the recess, the first pillar 13 and the second pillar 14 are fixedly connected.

[0051] Considering that the third section 144 of the through hole is used to accommodate part of the first pillar 13, the inner diameter of the third section 144 is larger than the inner diameter of the second section 143, and the inner diameter of the third section 144 is smaller than the inner diameter of the first section 142. The step formed between the third section 144 and the second section 143 is used to set a third locking member at the third section 144 after the first locking member is removed. The third locking member is specifically a bolt or a screw or a screw that cooperates with the third section. The third section 144 is also a threaded hole, which facilitates the separation of the first pillar and the second pillar by pulling force from the third locking member to the second pillar.

[0052] In some examples, considering the installation height of the cylinder 6 , the length of the second section 143 in the through hole is longer than the length of the first section 142 , and the length of the second section 143 is longer than the length of the third section 144 .

[0053] It is easy to understand that in this embodiment, reference Figure 5As shown, a second step is arranged in the circumferential direction of the second pillar 14. From one end of the second pillar 14 close to the first pillar 13 to the other end, the first cylindrical segment 141, the second cylindrical segment 145 and the third cylindrical segment 146 are arranged in sequence. The length of the first cylindrical segment 141 is longer than the length of the second cylindrical segment 145. The length of the second cylindrical segment 145 is longer than the length of the third cylindrical segment 146. A second step is arranged between the second cylindrical segment 145 and the third cylindrical segment 146. The outer diameter of the third cylindrical segment 146 is larger than the outer diameter of the second cylindrical segment 145. The outer diameter of the second cylindrical segment 145 is larger than the outer diameter of the third cylindrical segment 146. The diameter is greater than the outer diameter of the first cylindrical section 141, the annular partial cylindrical surface of the second cylindrical section 145 and the third cylindrical section 146 cooperate with the tipping paper lifter frame, and the tipping paper lifter frame structure is adapted to the second step of the second pillar 14 to position the installation position of the second pillar 14, thereby limiting the installation position of the second pillar 14, and the second pillar is finally limited by the limit screw 3, the limit screw 3 is eccentrically arranged relative to the second pillar, and the support pad at the limit screw 3 contacts with the end of the third cylindrical section 146 away from the second cylindrical section 145.

[0054] In addition, the first pillar 13 and the second pillar 14 are made of high-quality steel and adopt a suitable heat treatment process to meet the requirements of overall strength and wear resistance of the matching surface.

[0055] The pillar assembly provided in this embodiment is a split pillar assembly including a first pillar 13 and a second pillar 14. The first pillar 13 is used to connect with the cylinder 6. Removing the second locking member releases the limit on the second pillar. Removing the first locking member realizes the separation of the first pillar 13 and the second pillar 14, thereby realizing the rapid separation of the pillar assembly, thereby facilitating the removal of the cylinder 6 and greatly improving work efficiency. The first pillar is provided with an annular groove to install one end of the retaining spring, and the retaining spring fastening method is abandoned as a whole, thereby realizing the rapid separation of the cylinder and the pillar assembly, making it more convenient to replace the cylinder. The structure is sturdy and durable, and the disassembly and replacement are simple and easy, which effectively reduces the maintenance time and improves the production efficiency of the equipment.

[0056] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
