Description

Technical Field

[0001] The utility model relates to the technical field of sucker devices, in particular to a sucker device for preventing the box cover from falling off in a de-capping machine. Background Art

[0002] As is well known, boxing is an important process for box-type cigarette storage in the cigarette making workshop, and its operation stability directly affects the production continuity of the cigarette making workshop. Before boxing, the box cover of the cigarette box needs to be removed by a de-capping machine, a device currently in use. The de-capping machine mainly uses a cylinder to descend to the position of the box cover, uses an ordinary sucker to suck the box cover of the cigarette box, and then uses the cylinder to lift the sucker holding the box cover.

[0003] In actual production, it is found that during the start and stop process of the cylinder lifting and lowering, collisions occur between the sucker and the mounting plate, causing large vibrations. These vibrations cause the box cover to fall off the sucker, resulting in the de-capping machine stopping, the boxing process stopping, and requiring manual handling to restart, seriously affecting the production continuity of the cigarette making workshop.

[0004] Therefore, the key to solving the above technical problems is to develop a sucker device with a simple structure, flexibility, and strong practicability that can ensure that the box cover will not easily fall off due to vibrations. Summary of the Invention

[0005] To solve the many problems in the above background art, a sucker device for preventing the box cover from falling off in a de-capping machine of the present utility model is realized by adopting the following design structure and the following technical solutions:

[0006] As a sucker device for preventing the box cover from falling off in a de-capping machine of the present utility model, it includes:

[0007] A sucker assembly. The sucker device is composed of a plurality of components sequentially sleeved on a sliding rod, and the inside of the sucker device is a through cavity through-hole.

[0008] A mounting plate. Above the center position of the mounting plate, a cylinder is vertically provided. One end of the piston rod of the cylinder is fixedly connected to the mounting plate, and a plurality of through-holes are provided on the mounting plate.

[0009] Further, the sucker device includes: a sliding rod. The sliding rod is of a cylindrical structure, one end is in the shape of a hexagonal nut, and the other end is provided with a thread. The inside of the sliding rod is a through-hole.

[0010] A threaded sleeve rod. The threaded sleeve rod is of a structure with a through-hole inside and threads outside. The through-hole inside the threaded sleeve rod is sleeved with a linear bearing, and the external threads of the threaded sleeve rod are connected to an adjusting nut.

[0011] Suction cup, a through hole is provided in the middle of the suction cup, and a connecting component is slidably sleeved at the top of the suction cup, and the connecting component is used to connect the sliding rod and the suction cup;

[0012] Spring, the spring is sleeved outside the sliding rod, one end contacts the threaded sleeve rod, and the other end contacts the suction cup.

[0013] Further, the sliding rod includes: a threaded hole and a rubber block. The threaded hole is located inside the end of the sliding rod in the shape of a hexagonal nut and is used to connect the quick connector. The rubber block is pasted on the end face of the hexagonal nut to play a role in collision buffering.

[0014] Further, the threaded sleeve rod includes: a linear bearing and an adjusting nut. The linear bearing is sleeved on the sliding rod and is slidably connected to the sliding rod through the balls inside the linear bearing. The linear bearing can slide freely along the sliding rod. There are two groups of adjusting nuts for fixedly installing the suction cup device on the mounting plate.

[0015] Further, the linear bearing includes: The linear bearing and the threaded sleeve rod are installed by interference fit.

[0016] Further, the suction cup includes: a connecting component. One end of the connecting component is in the shape of a hexagonal nut, and the other end is in the shape of a cylinder. A threaded hole for threadedly cooperating with the end of the sliding rod is provided inside the hexagonal nut for connecting the sliding rod.

[0017] Further, the spring includes: One end of the spring is in contact connection with the connecting component, and the other end is in contact connection with the linear bearing. The spring is used for buffering and shock absorption.

[0018] Further, the quick connector includes: The quick connector is connected to the vacuum pump. The vacuum pump can extract all the gas remaining inside the suction cup and the gas inside the through hole of the sliding rod, so that a vacuum state is formed inside the suction cup. Under the action of the external atmospheric pressure, the suction cup can tightly hold the lid of the cigarette box.

[0019] Further, the mounting plate includes: A cylinder is vertically provided above the center position of the mounting plate. The cylinder is used to control the rising or falling of the suction cup assembly to achieve the sucking work on the lid of the cigarette box. The mounting plate is provided with a plurality of through holes for mounting the suction cup assembly, and the number of installations can be determined according to the quality and volume of the lid of the cigarette box.

[0020] Working principle of the utility model: The sucker device of the utility model is installed on the upper part of the gantry support (14), and the gantry support (14) is installed on the conveyor belt. The sucker assembly (1) of the sucker device is composed of many parts. The hexagonal nut end of the slide bar (3) is provided with a threaded hole (311) for connecting the quick connector (10). The rubber block (33) is sleeved outside the long rod of the slide bar and is closely adhered to the end face of the nut end. A linear bearing (5) is installed inside the threaded sleeve rod (4) by an interference fit method. The linear bearing (5) is also sleeved outside the long rod of the slide bar. The linear bearing (5) contacts the long rod of the slide bar (3) through the balls installed inside, so that the linear bearing (5) can freely slide along the long rod of the slide bar (3). The outside of the threaded sleeve rod (4) is provided with threads and is connected to two sets of adjusting nuts (6). The mounting plate (2) is located in the middle of the two sets of adjusting nuts (6). As long as the adjusting nuts (6) are tightened up and down, the sucker assembly (1) can be firmly installed on the mounting plate (2). The sucker (7) is made of a flexible material. The elastic property of the flexible material can tightly adsorb the connection assembly (8) located in the top groove. The threaded hole at the end of the connection assembly (8) and the threaded rod at the tail end of the long rod of the slide bar (3) are used together to stably install the sucker (7) at the tail of the slide bar (3). A spring (9) is arranged between the threaded sleeve rod (4) and the sucker (7). The upper end of the spring (9) contacts the end face of the linear bearing (5), and the lower end contacts the end face of the connection assembly (8), playing a role of shock absorption and buffering.

[0021] The entire suction cup assembly (1) is installed and fixed on the mounting plate (2) by means of an adjusting nut (6), and the quick connector (10) is connected to the vacuum pump (12) by means of an air pipe. During installation and use, the number of suction cup assemblies (1) to be installed and used is determined according to the model of the decapping machine, and the relative position of the adjusting nut (6) on the threaded sleeve (4) is changed to ensure that all suction cup assemblies (1) are on the same horizontal line. When it is necessary to suck the box cover, the piston rod of the cylinder (11) extends downward to push the suction cup device to contact the box cover, and the piston rod of the cylinder (11) continues to extend downward to further squeeze the suction cup (7) to discharge gas, thereby forming a closed space between the suction cup (7) and the box cover. In this process, the reaction force generated by the suction cup assembly (1) acts on the spring (9), causing the spring (9) to be compressed and deformed, thereby playing a buffering role. When the extended length of the piston rod of the cylinder (11) reaches the set length, the vacuum pump (12) is started to extract the gas in the cavity of the slide rod (3) and the gas inside the suction cup (7), so that the entire cavity becomes a vacuum state. Under the action of the external atmospheric pressure, the suction cup (7) can be tightly squeezed and fit on the cover of the cigarette box (13), thereby sucking the cover of the cigarette box (13). The piston rod of the cylinder (11) retracts upward, and the cover is lifted upward. In this process, if the distance and force of the upward retraction of the piston rod of the cylinder (11) change, the cover and the suction cup assembly (1) will be bumped up and down. Since the threaded sleeve rod (4) is firmly mounted on the mounting plate (2) through the adjusting nut (6), when the suction cup assembly (1) bumps up and down, the spring (9) will be compressed upward and the rubber block (33) will be squeezed downward, effectively avoiding the collision between important components when the suction cup assembly (1) bumps up and down, causing damage to the components.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] 1. The suction cup device involved in the utility model has a simple structure and is assembled from a plurality of parts. When installing or disassembling, it is only necessary to tighten or loosen the adjustment nut to complete the installation or disassembly operation, which can save a lot of installation cost and time.

[0024] 2. The suction cup device involved in the utility model can change the installation height of the entire suction cup device by changing the relative position of the adjustment nut on the threaded sleeve rod, thereby meeting the different requirements of different models of decapping machines for the working height of the suction cup device.

[0025] 3. The utility model uses springs and rubber blocks to implement double buffering and vibration reduction, which can not only reduce the significant vibration generated during the start and stop of the cylinder lifting, avoid the suction cup device from colliding with the mounting plate, and thus prevent the production accident of the cigarette box lid falling due to large vibration and causing the shutdown of the lid removing machine, but also reduce the damage of the components of the suction cup device caused by mutual collision due to vibration, enhance the stability of the suction cup device, and extend the service life of each component.

[0026] 4. The sliding rod of the utility model is in a state of being hollow inside. Its upper end is connected to the quick connector by threads, and the lower end is connected to the suction cup by threads. Other components are all sleeved outside the sliding rod. In this way, the airtightness of the gas passage can be ensured. When the vacuum pump starts and pumps out the gas, the internal vacuum state can last for a long time, ensuring that the suction force of the suction cup device on the box lid remains constant all the time, effectively avoiding the destruction of the vacuum environment due to air intake, and thus preventing the production accident of the box lid falling due to the reduction of the suction force and affecting the production efficiency.
