Description

Technical Field

[0001] This application relates to the field of tobacco manufacturing technology, specifically to a device for opening the lid of a rubber drum in a cigarette packaging workshop. Background Technology

[0002] In the daily production of cigarette manufacturing, the containers used to store glue are indispensable for maintaining the normal operation of the production line. Before these containers are put into use, the lids must be opened. However, the current lid-opening method commonly used in the industry is gradually showing a mismatch with the needs of efficient production.

[0003] Currently, operators mainly rely on two methods to open bucket lids: one is to use conventional tools such as screwdrivers and pry bars, inserting the tools into the gap between the lid and the bucket body, and slowly prying the lid off point by point. Throughout the process, the prying position of the tools needs to be constantly changed, which is not only cumbersome but also time-consuming; the other is to use a specially made simple lid-opening tool, which is inserted into the edge of the lid, and the lid is opened by continuously applying upward pulling or prying force manually. Although this method is slightly better than the first in terms of tool and lid compatibility, it still relies on human power, and the operator needs to exert continuous force to complete the operation.

[0004] Since both methods rely entirely on manual labor, on the one hand, the labor intensity of operators will increase significantly, and long-term operation will easily lead to fatigue; on the other hand, the opening process takes a long time, which is difficult to match with the high-speed production rhythm of cigarette factories, often causing a brief stop in the production process, affecting the continuity of production, and thus having an adverse impact on overall production efficiency.

[0005] Therefore, developing an automated device that can quickly and conveniently open cigarette can lids to replace the traditional manual method is of great practical significance for optimizing the production process of cigarette factories, improving production efficiency, and reducing the labor intensity of operators. Utility Model Content

[0006] The main purpose of this application is to provide a device for opening the lid of a plastic drum in a packaging workshop, which aims to solve the technical problems of low efficiency, high labor intensity, safety risks, and difficulty in adapting to different specifications of plastic drums in the prior art.

[0007] To achieve the above objectives, this application provides the following technical solution: A device for opening the lid of a plastic bucket in a packaging workshop includes a base plate, a base provided on the base plate, elongated holes on the left and right sides of the upper end face of the base, and a bucket body fixing mechanism provided in the middle. A motor is provided on the left side of the inner bottom wall of the base. The output end of the motor is locked with a lead screw through a coupling, and the other end of the lead screw is rotatably connected to the inner wall of the base through a bearing. A pair of connecting blocks are threaded on the outer wall of the lead screw. A connecting rod is provided on the top of the connecting blocks. The top of the connecting rod extends out of the elongated hole, and a clamp is provided on the top of the inner side wall. An anti-slip pad is provided on the inner side wall between the clamps. The bottom plate is provided with a cover opening mechanism on the top left side.

[0008] Furthermore, the lower fixing mechanism of the barrel includes a support base, the upper surface of the support base is provided with a groove, a vacuum suction cup is provided at the center of the bottom wall of the groove, and one end of the connecting tube is provided on the outer wall of the support base and is connected to the vacuum suction cup.

[0009] Furthermore, the opening mechanism includes a support column, a top plate at the top of the support column, a stabilizing rod on the outer wall between the support column and the top plate, a hydraulic telescopic rod on the right side of the outer wall of the top plate, and a vacuum suction cup on the driving bottom wall of the hydraulic telescopic rod.

[0010] Furthermore, the second vacuum suction cup is coaxial with the support base and is located directly above the support base.

[0011] Furthermore, the lead screw is a bidirectional lead screw, and a pair of connecting blocks are threadedly connected to the threads of different directions on the outer wall of the lead screw.

[0012] Furthermore, the outer ring of the bearing is fixedly connected to the inner wall of the base through the bearing seat, and the inner ring of the bearing is interference-fitted with the outer wall of the lead screw.

[0013] The technical solution provided in this application may include the following beneficial effects: During use, this application achieves automatic adsorption and lifting separation of the lid through the synergistic action of the vacuum suction cup and the hydraulic telescopic rod, replacing the traditional manual prying operation that relies on tools such as screwdrivers and pry bars. Operators only need to complete simple auxiliary actions such as placing the lid and starting the equipment, without having to exert continuous force, thus reducing physical exertion. It is especially suitable for high-frequency lid opening scenarios in cigarette factories.

[0014] The device employs a dual fixing structure of "bottom vacuum suction cup adsorption + outer wall clamping seat". This structure ensures a tight fit between the bottom of the container and the support base through the vacuum suction cup, while the clamping seat and anti-slip pad enhance the fixing strength of the container's side wall. This prevents the container from shaking, shifting, or even tipping over during the opening process, improving the stability of the opening operation and reducing safety hazards such as material spillage. It is also more advantageous for handling easily leaking materials such as glue.

[0015] The opening and closing range of the clamp can be adjusted by the motor and the lead screw, which can adapt to different sizes of barrels; the suction method of the vacuum suction cup has relatively flexible requirements for the flatness of the barrel lid surface, and does not require the operator to have superb prying skills, reducing the dependence on operating experience, facilitating rapid promotion and application, and reducing the problem of damage to the barrel and lid caused by improper manual operation.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] See Figure 1-2 As shown, a device for opening the lid of a plastic bucket in a packaging workshop includes a base plate 1, a base 2 on the base plate 1, elongated holes 3 on the left and right sides of the upper end face of the base 2, and a bucket lower fixing mechanism in the middle. A motor 7 is provided on the left side of the inner bottom wall of the base 2. The output end of the motor 7 is locked with a lead screw 8 through a coupling. The other end of the lead screw 8 is rotatably connected to the inner wall of the base 2 through a bearing 9. A pair of connecting blocks 10 are threaded on the outer wall of the lead screw 8. A connecting rod 11 is provided on the top of the connecting block 10. The top of the connecting rod 11 extends out of the elongated hole 3. A clamp 12 is provided on the top of the inner side wall. An anti-slip pad 13 is provided on the inner side wall between the clamps 12. A cover opening mechanism is provided on the top left side of the base plate 1.

[0021] Furthermore, the lower fixing mechanism of the barrel includes a support base 4, the upper surface of the support base 4 is provided with a groove, the bottom wall of the groove is provided with a vacuum suction cup 5 at the center, and the outer wall of the support base 4 is provided with one end of a connecting pipe 6, which is connected to the vacuum suction cup 5. The barrel is placed in the groove at the top of the support base 4, and the bottom of the barrel is adsorbed and fixed by the vacuum suction cup 5.

[0022] Furthermore, the lid opening mechanism includes a support column 14, a top plate 15 at the top of the support column 14, a stabilizing rod 16 on the outer wall between the support column 14 and the top plate 15, a hydraulic telescopic rod 17 on the right side of the outer wall of the top plate 15, and a vacuum suction cup 18 on the driving bottom wall of the hydraulic telescopic rod 17. After the hydraulic telescopic rod 17 is activated, it pushes the vacuum suction cup 18 to move downward, adsorbing and fixing the vacuum suction cup 18 onto the lid. The hydraulic telescopic rod 17 drives the vacuum suction cup 18 to pull the lid upward, separating the lid from the barrel body, thus realizing the lid opening operation.

[0023] Furthermore, the vacuum suction cup 2 18 is coaxial with the support base 4 and is located directly above the support base 4. The vacuum suction cup 2 18 is driven by the hydraulic telescopic rod 17 to pull the bucket lid upward, making it easy to separate the bucket lid from the bucket body.

[0024] Furthermore, the lead screw 8 is a bidirectional lead screw, and a pair of connecting blocks 10 are threaded onto the threads of different directions on the outer wall of the lead screw 8. After the motor 7 is started, the lead screw 8 is rotated. The lead screw 8 causes the two connecting blocks 10 to drive the connecting rod 11, the clamp 12 and the anti-slip pad 13 to move inward toward the barrel body at the same time to achieve a fixing effect, or to move outward away from the barrel body to break free from the fixing to the barrel body.

[0025] Furthermore, the outer ring of the bearing 9 is fixedly connected to the inner wall of the base 2 through the bearing seat, and the inner ring of the bearing 9 is interference-fitted with the outer wall of the lead screw 8. The bearing 9 fixes the lead screw 8, making it easier for the lead screw 8 to rotate through the bearing 9.

[0026] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.

[0027] One specific application of this embodiment is: When in use, first place the bucket to be opened stably in the groove at the top of the support base 4. The contour of the groove matches the bottom of the bucket, which can achieve the initial positioning of the bucket and avoid obvious displacement during placement. Activate the vacuum suction cup 5 to form a negative pressure inside. The negative pressure suction force will firmly fix the bottom of the bucket to the support base 4, completing the first fixation of the bucket. Subsequently, the motor 7 is started, and the power output of the motor 7 drives the lead screw 8 to rotate in a preset direction. Utilizing the thread transmission characteristics of the lead screw 8, the two connecting blocks 10 sleeved on the lead screw 8 move synchronously inward along the lead screw axis. Then, through the connecting rod 11, the clamping seat 12 and the anti-slip pad 13 on the inner side gradually approach the outer wall of the barrel. When the anti-slip pad 13 contacts the outer wall of the barrel, the motor 7 continues to run, so that the two clamping seats 12 form a symmetrical clamping force on the barrel. At this time, the anti-slip pad 13 adheres tightly to the outer wall of the barrel through its own elastic deformation, which increases the contact friction and prevents the barrel from rotating or sliding in subsequent operations. It also avoids the clamping seats 12 from causing hard squeezing damage to the barrel. The dual fixing method of bottom vacuum adsorption and outer wall clamping constrains the barrel from both the vertical and horizontal directions, improving the stability of the barrel during the opening process. After the bucket body is fixed, the piston rod of the hydraulic telescopic rod 17 is extended downward, pushing the vacuum suction cup 18 installed at its end to move vertically downward until the suction surface of the vacuum suction cup 18 is in complete contact with the surface of the bucket lid. At this time, the negative pressure system of the vacuum suction cup 18 is activated, so that it is firmly attached to the preset position of the bucket lid. After confirming that the attachment is firm, the piston rod of the hydraulic telescopic rod 17 is retracted upward, and the vacuum suction cup 18 applies a continuous and stable upward pulling force to the bucket lid, so that the sealing structure between the bucket lid and the bucket body gradually separates until the bucket lid is completely separated. After opening the lid, turn off the negative pressure of vacuum suction cup 18 and remove the separated lid; then reverse the start motor 7 to make the lead screw 8 rotate in the opposite direction, driving the connecting block 10, connecting rod 11, clamp 12 and anti-slip pad 13 to move outward, releasing the clamping constraint on the bucket; finally, turn off the negative pressure of vacuum suction cup 5 and smoothly remove the bucket from the groove of the support base 4 after opening the lid, completing the entire operation process.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
