Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production and packaging, in particular to a driving structure of a cigarette lowering control device of a tray loading machine and a tray loading machine. Background Art

[0002] Existing cigarette-discharging stopping devices in tray loading machines, such as the YJ35C model, include a drive mechanism formed by a cylinder controlled by a solenoid valve. This drive mechanism drives one toothed plate in the tray loading machine to move relative to the other toothed plate, so that the space enclosed by the teeth on the two plates is larger than, equal to, or smaller than the size of the cigarette, allowing or preventing the cigarette from passing through the two toothed plates.

[0003] First, the connection between the cylinder piston rod and the output support arm of the existing smoke stopping device is directly connected by bolts and nuts 36, which may get stuck during operation and is difficult to maintain.

[0004] On the other hand, due to the characteristics of the solenoid valve, it is impossible to adjust the force. The drive structure can only control opening and closing during operation. When the force is too large, the lower cigarette tooth plate will squeeze the cigarette to produce wrinkled cigarettes, or even break the cigarettes; when the force is too small, it is impossible to stop the fall of the cigarettes in time and effectively, resulting in problems such as excessive accumulation of cigarettes in the cigarette tray and horizontal cigarettes.

[0005] On the other hand, the solenoid valve of the original smoke stop device was tightly wrapped in a cover, which was not conducive to equipment maintenance. The heat generated during operation could not be dissipated in time and was not easy to detect. There were certain quality risks and even fire hazards during long-term operation.

[0006] Therefore, providing a better driving structure for the smoke lowering stopping device is a technical problem to be solved urgently in this field. Utility Model Content

[0007] The purpose of this application is to provide a better driving structure of the smoke stopping device to at least solve one of the above-mentioned technical problems.

[0009] Furthermore, the connecting piece between the piston portion and the support arm includes a bearing.

[0010] Furthermore, the plane where the movement trajectory of the support arm is located is parallel to the movement direction of the piston part and the distance therebetween is variable.

[0011] Furthermore, the connecting piece between the piston portion and the support arm includes a swing bolt and a nut screwed onto the swing bolt.

[0012] Furthermore, the control valve includes a solenoid valve.

[0013] Furthermore, the air intake volume of the cylinder is adjustable.

[0014] Furthermore, the control valve includes a proportional valve.

[0015] Furthermore, it includes an adjusting knob, which is connected to the proportional valve and controls the opening of the proportional valve.

[0016] Furthermore, it includes a base, the fixing part is fixedly arranged on the base, and the base is fixedly connected to the tray loading machine.

[0017] The second solution of the present application for solving the above-mentioned problem is a tray loading machine, and the driving structure of the lower smoke control device of the tray loading machine.

[0018] The beneficial effects of this application are:

[0019] 1. This application provides a drive structure for a tray loading machine's smoke control device, comprising an adjustable-speed cylinder.

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0028] Please refer to Figure 1-2 Some embodiments of the present application provide a driving structure for a smoke control device of a tray loading machine, comprising: a control valve 1; an air circuit whose opening and closing degree is controlled by the control valve 1; a cylinder 3 driven by the air circuit, the cylinder 3 comprising a fixed part 31 and a piston part 32; a support arm connected to the piston part and driven by the cylinder, the support arm being swingably connected to the piston part and capable of swinging along the connection with the piston part.

[0029] By controlling the opening and closing degree of the air circuit, the speed of the piston part of the cylinder 3 can be adjusted, and the speed and strength of the driving structure of the lower smoke control device of the tray loader can be further adjusted to avoid problems such as wrinkled smoke, broken smoke, and horizontal smoke caused by excessive or insufficient force when controlling the lower smoke for tray loading, thereby improving product quality and equipment operation efficiency.

[0030] The support arm 5 is used to transmit the motion of the piston portion 32 of the cylinder 3 to the tray loader's smoke discharging control device, such as a toothed plate. The swinging arrangement of the support arm 5 increases the rotational freedom of the drive structure of the tray loader's smoke discharging control device at the connection between the support arm 5 and the piston portion 32, thereby reducing the risk of jamming.

[0031] Specifically, in some embodiments, the connection between the piston portion 32 and the support arm 5 includes a bearing 34. The piston portion 32 of the cylinder 3 is connected to the support arm 5 via the bearing 34. The axial direction of the bearing is perpendicular to the length of the support arm 5 and the direction of movement of the piston portion 32 of the cylinder 3. Connecting the support arm 5 and the piston portion 32 of the cylinder 3 with the bearing 34 allows the connection to have a degree of freedom in the direction of rotation of the bearing 34, ensuring smooth swinging and reducing the occurrence of jamming.

[0032] In some embodiments, the plane of the motion trajectory of the support arm 5 is parallel to the motion direction of the piston portion 32, and the distance therebetween is adjustable. Implementing the present invention in this manner increases the degree of freedom of the drive structure of the tray loading machine's smoke control device in a direction perpendicular to both the motion directions of the support arm 5 and the piston portion 32, facilitating commissioning and maintenance.

[0033] Preferably, the connecting member between the piston portion 32 and the support arm 5 includes a pivot bolt 35 and a nut 36. The length of the pivot bolt 35 is slightly longer than the distance between the two parts to be connected. When the nut 36 is not completely tightened on the pivot bolt 35, the piston portion 32 and the support arm 5 can move within the range of the pivot bolt 35 and the nut 36, and the connection position can be adjusted within a certain range. That is, the plane of the movement trajectory of the support arm 5 is parallel to the movement direction of the piston portion 32 and the distance is adjustable. When a jam occurs, loosening the pivot bolt 35 can quickly release the jam and allow normal transmission. When the jam is released, tightening the pivot bolt 35 can maintain a more precise and stable fixed state.

[0034] The control valve 1 can be selected without limitation, as long as it can control the degree of opening and closing of the air circuit. For example, it can be at least one of a pneumatic valve, an electric actuator, a proportional valve, and a hydraulic valve. To fully utilize the original machine structure, in some embodiments, the control valve 1 includes a solenoid valve to control the opening and closing of the air circuit. As an implementation to adjust the speed of the cylinder 3, in some embodiments, the control valve 1 also includes a proportional valve to control the degree of opening and closing of the air circuit.

[0035] The method for adjusting the speed of cylinder 3 is not limited. In some embodiments, the amount of air entering cylinder 3 is adjusted, for example, by changing the opening of a throttle valve in the air circuit, the cross-sectional area of ​​the air inlet, the air pressure entering cylinder 3, etc. In some embodiments, the air circuit includes an air pipe 2 for connecting control valve 1 and cylinder 3. The amount of air in air pipe 2 is adjustable. For example, control valve 1 may include a proportional valve, and the amount of air entering air pipe 2 is controlled by controlling the opening of the proportional valve.

[0036] In some embodiments, an adjustment knob 11 is further included, which is used to adjust the air intake of the cylinder 3. The provision of the adjustment knob 11 can make the speed adjustment operation of the cylinder 3 more convenient and make the adjustment operation independent of the operation of controlling the opening and closing of the air circuit, thereby avoiding affecting stability and accuracy.

[0037] The mounting method for the drive structure of the tray loading machine's fume control device is not limited. In some embodiments, the drive structure further includes a base 4, to which the cylinder 3 is fixedly mounted, and the base 4 is fixedly connected to the tray loading machine. Preferably, the drive structure of the tray loading machine's fume control device is mounted on the tray loading machine with an open base 4 and connectors to enable an operator to control the adjustment knob 11 and to ensure sufficient heat dissipation during operation of the control valve 1. For example, the control valve can be directly fixed to the outside of the tray loading machine using threaded connectors.

[0038] The present application also provides a tray loading machine, comprising the aforementioned tray loading machine smoke control device driving structure, and having all the beneficial effects of the tray loading machine smoke control device driving structure.

[0039] The following combination Figure 1-2 List the specific embodiments of this application, such as Figure 1-2 As shown, Example 1 is a driving structure of a smoke control device for a tray loading machine, including: an air circuit, a control valve 1, and a cylinder 3.

[0040] The control valve 1 includes a solenoid valve and a proportional valve; an adjusting knob 11 is provided at the bottom of the control valve 1, which is connected to the proportional valve and controls the opening of the proportional valve, thereby controlling the air circuit and the air intake of the cylinder 3; the air circuit includes an air pipe 2 connecting the control valve 1 and the cylinder 3; the cylinder 3 is driven by the gas in the air circuit, and the cylinder 3 includes a fixing part 31 and a piston part 32; the fixing part 31 is fixedly arranged on the base 4, and the base 4 is fixedly connected to the tray loading machine.

[0041] This embodiment also includes a support arm 5, such as Figure 2 As shown, the end of the piston part 32 is provided with a threaded direct joint 33, a bearing seat is screwed on the threaded direct joint 33, and a bearing 34 is installed in the bearing seat; the support arm 5 is fixed to the inner ring of the bearing 34 by a movable bolt 35 and a nut 36, and can swing relative to the piston part 32 with the bearing 34 as the axis.

[0042] During operation, the piston 32 is extended or retracted by controlling the opening and closing of the solenoid valve, and the force of the extension or retraction of the piston 32 is controlled by rotating the adjustment knob 11. If a jam occurs, loosening the swing bolt 35 appropriately increases the distance between the support arm 5 and the piston 32, quickly releasing the jam and allowing normal transmission. Once the jam is resolved, tightening the swing bolt 35 maintains a highly precise and stable fixed position, ensuring safe and stable operation of the tray loading machine.

[0043] Example 2 is a tray loading machine, comprising the tray loading machine fume control device drive structure of Example 1, an equipment base for mounting the fume control device drive structure, and two toothed plates for controlling fume discharge. The support arm 5 of Example 1 is connected to one of the toothed plates, the base 4 is welded to the equipment base, and the control valve 1 is mounted directly to the equipment base via screws.

[0044] When unloading cigarettes, Example 1 drives one tooth plate and the other tooth plate in the tray loading machine to move closer to each other, so that the space enclosed by the tooth pins on the two tooth plates is larger than or equal to the size of the cigarette, and the cigarette passes through the two tooth plates.

[0045] When the cigarettes stop being unloaded, Example 1 drives one tooth plate and the other tooth plate in the tray loading machine to move away from each other, so that the space enclosed by the tooth pins on the two tooth plates is smaller than the size of the cigarettes, and the cigarettes cannot pass through the two tooth plates.
