Description

Technical Field

[0001] This disclosure pertains to the field of cigarette production technology, specifically relating to a negative pressure disc adjustment device for the inner lining paper of a packaging machine. Background Technology

[0002] The statements herein provide only background information in relation to this disclosure and do not necessarily constitute prior art.

[0003] The inner liner paper of cigarette packaging is rolled before packaging and is cut by the negative pressure cutting device of the packaging machine. The cut inner liner paper is then conveyed to the next process by a negative pressure plate. The negative pressure plate on the packaging machine usually consists of two side negative pressure plates and two sets of middle negative pressure plates. The inner liner paper cutter and the two side negative pressure plates move synchronously through gear transmission. The middle negative pressure plate is connected to the drive shaft through a toothed belt, and the gear at the other end of the drive shaft rotates synchronously with the two side negative pressure plates. During production, the toothed belt may wear or break and needs to be replaced. When replacing the toothed belt, it is necessary to ensure that the suction holes of the middle negative pressure plate are aligned synchronously with those of the two side negative pressure plates.

[0004] Currently, replacing the toothed belt requires disassembling the eccentric disc, breaking down the toothed belt housing, replacing the toothed belt, and then aligning the protrusion on the eccentric disc's toothed belt pulley with the groove at the gear transmission output end. Using the suction hole of the right-side negative pressure disc as a reference, a steel ruler is used to check the position of the corresponding suction holes on the middle and right-side negative pressure discs to ensure alignment. However, the following problems exist in the actual adjustment process: First, the adjustment operation is inconvenient. Because the inner lining paper negative pressure cutting device is installed longitudinally, the trolley handle faces the operator, requiring the operator to bend over and turn sideways for adjustment and inspection. Furthermore, the cutting device has a cutter, making the installation of the toothed belt housing and inspection of the negative pressure disc inconvenient and posing a safety hazard. Second, the adjustment steps are cumbersome. After replacing the toothed belt, half of the toothed belt housing needs to be installed first to check the position of the suction holes. Inaccurate positioning requires disassembling the toothed belt housing, readjusting and reinstalling the toothed belt, then reinstalling the toothed belt housing, checking the position of the negative pressure plate, and repeating the installation and testing process. After accurate installation, the toothed belt housing is disassembled again, the entire housing is reassembled, and finally the eccentric plate is installed. This process is cumbersome and time-consuming, often requiring considerable disassembly and assembly experience to calibrate the suction hole position of the negative pressure plate after installation. Thirdly, inaccurate adjustments can occur because the steel ruler used may slightly deform during inspection. To ensure that the steel ruler is aligned horizontally with the center of the right negative pressure plate hole and the middle negative pressure plate suction hole, visual inspection alone may result in misalignment, causing misalignment of the toothed belt teeth. To ensure positional accuracy, repeated inspections are necessary. Furthermore, inaccurate positioning can affect the inner liner paper feeding, increase auxiliary material consumption, and increase the labor intensity of employees. Utility Model Content

[0005] The purpose of this disclosure is to provide a negative pressure disc adjustment device for the inner lining paper of a packaging machine, which can at least solve one of the above-mentioned technical problems.

[0006] To achieve the above objectives, one or more embodiments of this disclosure provide a negative pressure disc adjustment device for inner lining paper of a packaging machine, including a calibration device and a positioning block. The calibration device includes a calibration plate and sliding supports and locking wheel sleeves disposed at both ends of the calibration plate. The sliding supports are provided with pins for positioning with the suction holes of the negative pressure disc. A connecting plate and a positioning plate for connecting the locking wheel sleeve are disposed between the sliding supports. The connecting plate is connected to the locking wheel sleeve by bolts. The locking wheel sleeve is sleeved on the positioning block.

[0007] Furthermore, the positioning block is provided with a locking handle for adjusting the tightness of the locking wheel sleeve after it is connected to the positioning block.

[0008] Furthermore, the positioning plate is provided with a through hole for connecting the connecting plate, and the positioning plate and the connecting plate are connected by bolts.

[0009] Furthermore, a sliding groove is provided at the position where the connecting plate connects to the positioning plate.

[0010] Furthermore, the ejector pin is a spring ejector pin, and the bottom of the sliding support is fixed with a set screw.

[0011] Furthermore, the positioning plate and the calibration plate are vertically fixedly connected.

[0012] Furthermore, one end of the positioning block is provided with a magnetic protrusion and a bushing, and the other end is provided with a groove.

[0013] Furthermore, the protrusion matches the groove at the output end of the gear transmission.

[0014] Furthermore, the bushing can slide along the protrusion and fit over the groove of the protrusion and the gear transmission output end.

[0015] Furthermore, the bushing is fixed in position by a set screw.

[0016] The beneficial effects of one or more of the above technical solutions are as follows:

[0017] This disclosure solves the problem of visually determining the position using a steel ruler by using a sliding support with a pin on the calibration plate. This allows the pin on one end of the sliding support to contact the suction hole of the negative pressure plate on the right side, and the other end to contact the suction hole of the middle negative pressure plate. It eliminates the need for repeated adjustments of the toothed belt, ensuring that the position of the suction hole of the middle negative pressure plate is synchronized with that of the suction holes of the two negative pressure plates, thus guaranteeing the accuracy of the calibration and greatly reducing the difficulty of calibration. At the same time, it avoids the problem of adjusting the eccentric plate on the negative pressure cutting device and then disassembling and reassembling it, thereby improving the efficiency of calibration.

[0024] like Figures 1-4 As shown, this embodiment provides a negative pressure disc adjustment device for inner lining paper of a packaging machine, including a calibration device and a positioning block. The calibration device includes a calibration plate 7 and sliding supports 8 and locking wheel sleeves 2 set at both ends of the calibration plate 7. The sliding supports 8 are provided with pins 9 for positioning with the suction holes of the negative pressure disc. A connecting plate 1 and a positioning plate 4 connecting the locking wheel sleeve 2 are provided between the sliding supports 8. The connecting plate 1 is connected to the locking wheel sleeve 2 by bolts. A sliding groove is provided at the position where the connecting plate 1 and the positioning plate 4 are connected.

[0025] Specifically, the calibration plate 7 is a rectangular plate. The length of the calibration plate 7 is greater than the distance between the output end of the gear transmission and the suction hole of the middle negative pressure plate. One end of the calibration plate 7 is provided with a sliding support 8. The sliding support 8 has a pin 9. The pin 9 contacts the suction hole of the negative pressure plate on the right side. There is no need to visually determine the position of the calibration plate 7 and the suction hole of the middle negative pressure plate, which facilitates quick positioning operation.

[0026] A magnetic protrusion and a bushing 6 are designed at one end of the positioning block 3. The protrusion and bushing 6 ensure the stability and positioning of the connection between the end of the positioning block 3 with the protrusion and the groove at the output end of the gear transmission. The other end is provided with a groove, which determines the position of the eccentric disc toothed belt. The eccentric disc protrusion is inserted into the groove of the positioning block 3, which facilitates the subsequent assembly and connection of the intermediate negative pressure plate component. At the same time, the eccentric disc protrusion of the intermediate negative pressure plate and the groove at the output end of the gear transmission are correspondingly matched.

[0027] Specifically, the bushing 6 on the positioning block 3 can slide freely axially along one end of the protrusion on the positioning block 3. It can not only fit around the protrusion, but also tightly fit around the groove at the output end of the gear transmission, thereby further enhancing the stability of the connection. To ensure that the position of the bushing 6 remains fixed during use, a set screw is provided on the bushing 6 to lock its position. This can prevent the bushing 6 from shifting due to vibration or other external forces, thus ensuring the reliability of the entire calibration device during use.

[0028] Specifically, the locking wheel sleeve 2 is fitted onto the positioning block 3. The locking wheel sleeve 2 is equipped with a locking handle 5 for adjusting the tightness of the connection between the locking wheel sleeve 2 and the positioning block 3. The locking handle 5 is rotatably connected to the positioning block 3. The locking handle 5 allows the operator to fix the position between the locking wheel sleeve 2 and the positioning block 3, thereby ensuring that the positions of the protrusions and grooves at both ends of the positioning block 3 are consistent with the installation positions of the grooves on the drive shaft and the eccentric disc protrusions on the middle negative pressure plate drive shaft, preventing unnecessary rotation of the positioning block 3 when subjected to external forces.

[0029] The positioning plate 4 and the calibration plate 7 are vertically fixedly connected. The positioning plate 4 is provided with a through hole for connecting the connecting plate 1. The positioning plate 4 and the connecting plate 1 are connected by bolts. This ensures the stability of the structure and facilitates disassembly and maintenance.

[0030] The ejector pin 9 is a spring ejector pin, which can provide a certain elasticity, so that the ejector pin 9 can better contact the suction hole of the negative pressure plate during use. The bottom of the sliding support 8 is fixed with a set screw, which can ensure the stability of the sliding support 8 during operation and prevent it from moving unnecessarily when subjected to external force, thereby ensuring the accuracy and reliability of the entire adjustment device.

[0031] Working principle:

[0032] In use, the adjustment device is first connected to the positioning block 3 of the device through the gear transmission output end. The protrusion on the positioning block 3 is inserted into the gear transmission output end, and the connection part is covered by the bushing 6. Then, the circumferential position of the calibration plate 7 is determined through the suction hole of the negative pressure plate on the right. Then, the locking handle 5 is adjusted to fix the angular offset position between the locking wheel sleeve 2 and the positioning block 3 at this time. Taking the position of the adjustment device at this time and the position between the right negative pressure plate as the reference position, the adjustment device is removed. Then, the adjustment device is connected to the middle negative pressure plate. The suction hole on the middle negative pressure plate contacts the pin 9 on the sliding support 8 on the left side of the adjustment device to determine the position of the toothed pulley on the middle negative pressure plate. At the same time, the position of the toothed pulley of the eccentric plate is determined by the groove set on the positioning block 3, and the toothed belt is installed to ensure that the position of the suction hole on the middle negative pressure plate corresponds to the position of the suction hole on the right negative pressure plate.

[0033] After the toothed belt is installed, since the position of the air intake hole of the middle negative pressure plate and the position of the air intake port of the side negative pressure plate have been calibrated and aligned, the eccentric disk drive shaft on the middle negative pressure plate and the gear drive output end on the side negative pressure plate can be directly connected.

[0034] While the specific embodiments of this disclosure have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this disclosure. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this disclosure are still within the scope of protection of this disclosure.
