[0001] The utility model relates to the technical field of sealing machines, and more specifically, to a sealing machine that facilitates the opening and closing of the upper cover. Background Art

[0002] The upper cover and the sealing machine body of a sealing machine are its core components. The upper cover is used to enclose the working area to ensure safety and prevent material leakage. It is usually made of heat-resistant and corrosion-resistant materials. The sealing machine body bears all internal components, such as heating elements and control panels, and is usually made of strong metal to ensure stability and durability. Its working principle is to separate the upper cover and the sealing machine body, place the opening of the plastic bag between the upper cover and the sealing machine body, and then close the upper cover for sealing. However, in this process, in the prior art, it is often necessary to lock the sealing machine body and the upper cover again through buckles, etc. This leads to the situation that in occasions where quick sealing is required, the existing opening and closing methods may not meet the requirements of efficient operation. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a sealing machine that is convenient for opening and closing, so as to solve the technical problem that in the prior art, it is necessary to lock the sealing machine body and the upper cover again through buckles, etc., which leads to the situation that in occasions where quick sealing is required, the existing opening and closing methods may not meet the requirements of efficient operation.

[0004] To solve the above technical problems, the utility model provides the following technical solution: A sealing machine that facilitates the opening and closing of the upper cover, including a sealing machine body and an upper cover body. The upper cover body is hinged to the top of the sealing machine body through a torsion spring. Symmetrically arranged connecting grooves are opened at the top of the sealing machine body, and clamping grooves are opened on the inner walls of the connecting grooves. A connecting column corresponding to the connecting groove is fixedly connected to the bottom of the upper cover body. The inside of the connecting column is hollow, and receiving grooves are opened on the outer walls of the connecting columns. Elastic members are arranged in the receiving grooves. One end of the elastic member penetrates through the receiving groove into the inside of the connecting column and is slidably connected to the penetrated part thereof. The other ends of the elastic members can be respectively inserted into the clamping grooves. A pressing plate is hinged to the outer wall of the upper cover body through a torsion spring. An adjusting mechanism for adjusting the position of the elastic member is arranged in each connecting column;

[0005] The adjusting mechanism includes a guiding block slidably connected to the inner wall of the connecting column. The guiding block has a triangular structure. A limiting tube is arranged inside the connecting column. The top of the limiting tube sequentially penetrates through the connecting column and the upper cover body. A push column is arranged inside the limiting tube. Both ends of the push column respectively penetrate through the top and bottom of the limiting tube and are movably connected to the penetrated parts inside it. The bottom of the push column is rotatably connected to the top of the guiding block. A tension spring sleeving the push column is fixedly connected to the top of the guiding block. The other end of the tension spring is fixedly connected to the inner wall of the top of the connecting column. A compression spring is arranged on the outer wall of the elastic member. The other end of the compression spring is fixedly connected to the inner wall of the connecting column. A fixing component for fixing the position of the push column is arranged inside the limiting tube;

[0006] The fixing component includes a plurality of sliders. The sliders are uniformly and fixedly connected to the outer wall of the push column. A plurality of strip-shaped limiting plates are uniformly and fixedly connected to the inner wall of the limiting tube. A plurality of inclined baffles are fixedly connected to the inner wall of the limiting tube; When it is necessary to quickly close the upper cover body and the sealing machine body, by pressing the pressing plate, the pressing plate drives the upper cover body to twist and close with the sealing machine body. Subsequently, the pressing plate twists and squeezes the push column in the adjusting mechanism, so that the push column moves and pushes the elastic member to move, making the elastic member move and insert into the card slot. During this process, the limiting plates in the fixing component will limit the sliders, so that the push column cannot move further, thus completing the quick locking after the upper cover body and the sealing machine body are closed. When it is necessary to open the upper cover body and the sealing machine body, similarly, pressing the pressing plate again can make the upper cover body automatically twist and open. The whole process requires no extra operations, which is simple and convenient.

[0007] Preferably, both sides of the bottom of the limiting plate are recessed towards the middle, and both sides of both ends of the slider are inclined towards the middle to form protrusions; The recess formed by the limiting plate will catch the protrusion formed by the slider, increasing the stability when the limiting plate limits the slider.

[0008] Preferably, one end of the elastic member inserted into the card slot extends obliquely towards both sides to form a "Y"-shaped structure, and the outer wall of the extended elastic member abuts against the inner walls of the top and bottom of the card slot respectively; The "Y"-shaped structure formed by the elastic member makes it, when inserted into the card slot, under its own elasticity, abut against the inner walls of the top and bottom of the card slot and closely fit with them through its own elasticity, thereby increasing the stability when the elastic member is inserted into the card slot and locking the upper cover body through the connecting column.

[0009] Preferably, the other end of the elastic member extends obliquely upward, and the outer wall of the elastic member after the oblique extension is attached to the inclined outer wall of the guiding block. The outer wall of the elastic member after the inclination causes mutual guidance between the elastic member and the guiding block when they come into contact, thereby preventing the guiding blocks from getting stuck with each other when pushing the elastic member.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. Through the sealing machine body, the upper cover body, the connecting groove, the clamping groove, the connecting column, the storage groove, the elastic member, the pressing plate and the adjusting mechanism, by pressing the pressing plate, the pressing plate drives the upper cover body to twist and close with the sealing machine body. Subsequently, the pressing plate twists to push the push column in the adjusting mechanism, so that the push column moves and pushes the elastic member to move, making the elastic member move and insert into the clamping groove. During this process, the limiting plate in the fixing component will limit the slider, so that the push column cannot move further, thus completing the quick locking after the upper cover body and the sealing machine body are closed. When it is necessary to open the upper cover body and the sealing machine body, similarly, pressing the pressing plate again can make the upper cover body automatically twist and open. The whole process requires no extra operations, which is simple and convenient.

[0012] 2. One end of the elastic member inserted into the clamping groove extends obliquely to both sides to form a "Y" - shaped structure. The "Y" - shaped structure formed by the elastic member causes it to, under its own elasticity, abut against the top and bottom inner walls of the clamping groove and closely fit with them through its own elasticity, thereby increasing the stability when the elastic member is inserted into the clamping groove and locking the upper cover body through the connecting column.

[0021] As Figures 1 to 6 shown, the utility model relates to a sealing machine facilitating the opening and closing of the upper cover, including a sealing machine body 1 and an upper cover body 2. The upper cover body 2 is hinged to the top of the sealing machine body 1 through a torsion spring. Symmetrically arranged connecting grooves 3 are formed in the top of the sealing machine body 1, and card slots 4 are formed in the inner walls of the connecting grooves 3. A connecting column 5 corresponding to the connecting groove 3 is fixedly connected to the bottom of the upper cover body 2. The inside of the connecting column 5 is hollow, and storage grooves 6 are formed in the outer walls of the connecting column 5. Elastic members 7 are arranged in the storage grooves 6. One end of each elastic member 7 penetrates through the storage groove 6 into the inside of the connecting column 5 and is slidably connected to the penetrated position thereof, and the other end of each elastic member 7 can be inserted into the card slot 4 respectively. A pressing plate 8 is hinged to the outer wall of the upper cover body 2 through a torsion spring, and an adjusting mechanism for adjusting the position of the elastic member 7 is arranged in each connecting column 5;

[0022] The adjusting mechanism includes a guide block 9 slidably connected to the inner wall of the connecting column 5. The guide block 9 is of a triangular structure. A limiting tube 10 is arranged in the connecting column 5. The top of the limiting tube 10 penetrates through the connecting column 5 and the upper cover body 2 in sequence. A pushing column 11 is arranged in the limiting tube 10. Both ends of the pushing column 11 penetrate through the top and the bottom of the limiting tube 10 respectively and are movably connected to the penetrated positions therein. The bottom of the pushing column 11 is rotatably connected to the top of the guide block 9. A tensile spring 12 sleeving the pushing column 11 is fixedly connected to the top of the guide block 9, and the other end of the tensile spring 12 is fixedly connected to the inner wall of the top of the connecting column 5. A compression spring 13 is arranged on the outer wall of the elastic member 7, and the other end of the compression spring 13 is fixedly connected to the inner wall of the connecting column 5. A fixing component for fixing the position of the pushing column 11 is arranged in the limiting tube 10;

[0023] The fixing component includes a plurality of sliders 14, which are uniformly and fixedly connected to the outer wall of the push rod 11. A plurality of strip-shaped limiting plates 15 are uniformly and fixedly connected to the inner wall of the limiting tube 10, and a plurality of inclined baffles 16 are fixedly connected to the inner wall of the limiting tube 10. When it is necessary to quickly close the upper cover body 2 and the sealing machine body 1, by pressing the pressing plate 8, the pressing plate 8 drives the upper cover body 2 to twist and close with the sealing machine body 1. Subsequently, the pressing plate 8 twists and squeezes the push rod 11 in the adjusting mechanism, so that the push rod 11 moves and pushes the elastic member 7 to move, making the elastic member 7 move and insert into the card slot 4. During this process, the limiting plate 15 in the fixing component will limit the slider 14, so that the push rod 11 cannot continue to move, thus completing the quick locking after the upper cover body 2 and the sealing machine body 1 are closed. When it is necessary to open the upper cover body 2 and the sealing machine body 1, similarly, pressing the pressing plate 8 again can make the upper cover body 2 automatically twist and open. The whole process requires no extra operations, which is simple and convenient.

[0024] Further, both sides of the bottom of the limiting plate 15 are recessed towards the middle, and both sides of the two ends of the slider 14 are inclined towards the middle to form protrusions; the recess formed by the limiting plate 15 will catch the protrusion formed by the slider 14, increasing the stability when the limiting plate 15 limits the slider 14.

[0025] Further, one end of the elastic member 7 inserted into the card slot 4 extends obliquely towards both sides to form a "Y"-shaped structure, and the outer walls of the elastic member 7 after extension are respectively in contact with the top and bottom inner walls of the card slot 4; the "Y"-shaped structure formed by the elastic member 7 makes it, when inserted into the card slot 4, under its own elasticity, abut against the top and bottom inner walls of the card slot 4 and fit tightly with them through its own elasticity, thereby increasing the stability when the elastic member 7 is inserted into the card slot 4 and locking the upper cover body 2 through the connecting column 5.

[0026] Further, the other end of the elastic member 7 extends obliquely upwards, and the outer wall of the elastic member 7 after oblique extension is in contact with the inclined outer wall of the guiding block 9. The outer wall of the elastic member 7 after being inclined makes it, when in contact with the guiding block 9, mutually guide with the guiding block 9, thus preventing the guiding blocks 9 from getting stuck with each other when squeezing the elastic member 7.

[0027] Working principle: This embodiment provides a sealing machine that is convenient for opening and closing the upper cover. When in use, when it is necessary to close the upper cover body 2 and the sealing machine body 1, by pressing the pressing plate 8, the pressing plate 8 drives the upper cover body 2 to twist and complete the closing with the sealing machine body 1. At this time, continue to press the pressing plate 8, so that the pressing plate 8 itself twists on the outer wall of the upper cover body 2, thereby making the pressing plate 8 squeeze the push rod 11, causing the push rod 11 to start moving;

[0028] When the push post 11 moves downward, it will drive the guiding block 9 to move downward. The downward movement of the guiding block 9 squeezes the elastic member 7, so that the elastic member 7 is inserted into the card slot 4, and the elastic member 7 locks the upper cover body 2 through the connecting post 5. At the same time, during the downward movement of the push post 11, the push post 11 will drive the slider 14 to move downward. As the slider 14 moves downward, the slider 14 will contact the inclined baffle 16 and be blocked and guided by the inclined baffle 16, so that the slider 14 drives the push post 11 to rotate. Subsequently, the tension spring 12 will drive the guiding block 9 to squeeze the push post 11 under its own tension, so that the push post 11 drives the slider 14 to move and engage with the limiting plate 15, so that the elastic member 7 cannot be withdrawn from the card slot 4 at this time, thus preventing the upper cover body 2 from being opened from the sealing machine body 1;

[0029] When the upper cover body 2 needs to be opened, similarly, press the pressing plate 8 again, so that the slider 14 rotates again and cannot be engaged with the limiting plate 15, so that the guiding plate moves back under the elastic force of the tension spring 12 and no longer squeezes the elastic member 7. At this time, the elastic member 7 will also move back under the elastic force of the compression spring 13 and withdraw from the card slot 4 and return to the storage groove 6. At this time, the upper cover body 2 will rotate under the torsion of its own torsion spring to complete the opening.

[0030] The embodiments disclosed in the present invention are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
