Abstract
Description
Technical Field
[0001] This invention relates to the field of cigarette manufacturing technology, and in particular to a cigarette box opening support device. Background Technology
[0002] In a cigarette production line, the cigarette box opening device is a crucial component, directly affecting the next step of inserting cigarettes into the box, and even the overall production efficiency of the equipment.
[0003] In this sequence, the opening device plays a key role, responsible for opening the cigarette box to accelerate its transfer to the next process, and then the cigarettes are inserted into the box.
[0004] Currently, the equipment only uses ordinary support plates. In actual operation, after the support plate is removed from the cigarette box, the support plate is prone to springing back at the cigarette box support, causing the support to shrink. This will interfere with the normal operation of subsequent processes. Utility Model Content
[0005] The purpose of this invention is to solve the problems mentioned in the background art by providing a device that heats the cigarette box support plate so that the cigarette box can still maintain the shape of the support plate after it is opened.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a cigarette box support device, with the following structure: including a cigarette box support plate,
[0007] The front end of the cigarette box support plate consists of a guide body and a first support plate, both of which are trapezoidal structures. The second support plate is a frame structure and is fixed to the outside of the cigarette box support plate. The second support plate has an arc-shaped groove on the side adjacent to the first support plate.
[0008] In the above-mentioned cigarette box equipment support device, the second support plate is fixed at any position outside the cigarette box support plate.
[0009] The structure of the above-mentioned cigarette box opening support device is as follows:
[0010] The upper part of the stand is connected to the cigarette box support plate via a slide rail. The front end of the cigarette box support plate consists of a guide body and a first support plate. Both the guide body and the first support plate are trapezoidal structures. The second support plate is a frame structure and is fixed to the outside of the cigarette box support plate. The side of the second support plate adjacent to the first support plate has an arc groove. A heating rod is installed inside the cigarette box support plate. The cylinder is connected to the main body of the support plate.
[0011] The aforementioned cigarette box support device includes a thermocouple installed inside the support plate, which is connected to a heating rod. The thermocouple acts as a sensor, converting thermal energy into electrical energy, and measures and controls the temperature of the heating rod within the support plate.
[0012] In the aforementioned cigarette box support device, a heat insulation plate is provided between the cigarette box support plate and the cylinder. The heat insulation plate separates the high-temperature cigarette box support plate from the cylinder, preventing problems such as reduced cylinder life caused by high temperature.
[0013] The aforementioned cigarette box support device has a guide body with four sides at an angle of 11° and a first support plate with four sides at an angle of 45°. A cylinder acts as a device to push the cigarette box support plate in and out of the cigarette box.
[0014] The cigarette box opening support plate is the core component of the entire opening equipment. Its product design structure is based on the highest efficiency, highest precision, and highest yield in actual production. The trapezoidal guide angle design and the first opening support plate angle design are both optimal solutions. When cigarette boxes of different paper materials arrive at the opening device, the built-in heating rod heats the entire cigarette box opening support plate to the set temperature. The cigarette box opening support plate contacts and opens the opening of the cigarette box. Due to the thermal contact between the opening of the cigarette box and the heating plate, the high temperature causes the macromolecules to relax, which can eliminate some internal stress and improve the shape stability of the fibers.
[0015] The advantages of this utility model are as follows: Compared with the existing support device, the heat-fixing component designed in this utility model is simpler and more efficient. On the one hand, it can quickly and easily fix the shape of the cigarette box opening, making it convenient for subsequent equipment to quickly and accurately feed the cigarette into the cigarette box. On the other hand, if there are different styles of cigarette boxes, the cigarette box support plate can be directly replaced, which basically requires no maintenance and can reduce the maintenance cost in the production and use process.
[0016] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] A cigarette box device with a support opening, such as Figure 1 , Figure 2 As shown, the structure is as follows: The upper part of the stand 14 is connected to the cigarette box support plate 11 via a slide rail. The front end of the cigarette box support plate 11 consists of a guide body 16 and a first support plate 17. The guide body 16 and the first support plate 17 are trapezoidal structures that gradually increase in size. The second support plate 18 is a frame structure and is fixed to the outside of the cigarette box support plate 11. The second support plate 18 has an arc-shaped groove on the side adjacent to the first support plate 17. A heating rod is provided inside the cigarette box support plate 11. The cylinder 15 is connected to the support plate body 1.
[0023] A heating rod is installed inside the cigarette box support plate 11, and a cylinder 15 is connected to the support plate body 1. A heat insulation plate 12 is installed between the support plate body 1 and the cylinder 15. A thermocouple 13 is installed inside the cigarette box support plate 11 and is connected to the heating rod. A sensor is also installed on the cigarette box support device to sense the position of the cigarette box.
[0024] The cigarette box support plate 11 is the core component of the entire support device. Its design structure is based on the highest efficiency, accuracy, and yield in actual production. The angles of the guide body 16 and the first support plate 17 are optimal. The openings on both sides of the cigarette box opening 2 are approximately 15°. The guide body 16 designed in this invention has an opening of 11° on one side, allowing for support operation without touching the cigarette box opening 2 and preventing damage to the cigarette box. The first support plate 17 has an opening of 45° on one side, meaning that the upper contact part 171, the lower contact part 172, the left contact part 173, and the right contact part 174 of the first support plate form angles of 45° with the horizontal and vertical directions, respectively. The built-in heating rod heats the cigarette box support plate 11 to the set temperature. The second support plate 17 contacts the four sides and opens the cigarette box opening 2. The cigarette box opening 2 is thermally fixed by the heated cigarette box support plate 11. The high temperature causes the macromolecules to relax, which can eliminate some internal stress and improve the shape stability of the fiber.
[0025] An unopened cigarette box is fixed on a turntable. When the turntable moves to the position of the cigarette box opening device, the sensor of the opening device detects this and activates the opening device. Cylinder 15 pushes the cigarette box opening plate 11 partially into the cigarette box along the opening direction. At this time, guide body 16 guides the opening into the unopened cigarette box. The four-sided contact portion of the first opening plate 17 contacts and opens the cigarette box opening 2. The function of the second opening plate 18 is that after the first opening plate 17 opens the cigarette box opening, the flaps of the cigarette box opening move along the arc groove of the second opening plate 18 until it is fully opened, ready for the next process. Because the cigarette box opening plate 11 has a built-in heating rod, the cigarette box opening 2 is more easily fixed in shape after being heated. After a short pause, cylinder 15 moves, and the cigarette box opening plate 11 is withdrawn from the cigarette box along the opening direction.
[0026] It should be further explained that in cigarette manufacturing equipment, the cigarette box opening device is indispensable and plays a crucial role in improving production efficiency.
