[0018] The following will be described in detail with reference to the accompanying drawings. Figures 1-4 The present application will be further described in detail.

[0019] The embodiment of the present application discloses a linear heat sealing machine. Referring to Figure 1 , Figure 2 andFigure 3 , including the base 1, on the base 1 is provided with the base 2 and hot press mold 3, hot press mold 3 up and down sliding connection on the base 1, on the base 1 is provided with driving device 4 for driving hot press mold 3 up and down movement, the driving device 4 is a cylinder, the piston rod of the cylinder is fixedly connected with the hot press mold 3, the cylinder is connected with the air pump, the base 2 and hot press mold 3 up and down corresponding setting, the base 2 is horizontally sliding connection on the base 1, the base 2 and the base 1 between is equipped with positioning piece 5, on the base 2 is provided with positioning block 6, on the base 2 is provided with the sliding groove 7 for positioning block 6 up and down sliding, the sliding groove 7 bottom and the positioning block 6 between is equipped with elastic element 8, the positioning block 6 up and down slidingly arranged in the sliding groove 7, the inner end of the positioning block 6 is abutted on the elastic element 8, the outer end of the positioning block 6 extends to the outside of the sliding groove 7, the high temperature adhesive tape 9 is arranged on the outer end of the positioning block 6, the high temperature adhesive tape 9 extends to the outside of the positioning block 6 relative to the side of the positioning block 6 for abutting the product, the high temperature adhesive tape 9 can protect the product, so that the hot press mold 3 is not easy to scald the product.

[0020] Again in combination Figure 4 As shown, the positioning piece 5 is a bolt, the waist type hole 15 for the horizontal sliding of the bolt is arranged on the base 1, the waist type hole 15 penetrates the base 1 up and down, the threaded section of the bolt passes through the waist type hole 15 and is threadedly connected with the base 2, the step groove 16 for hiding the nut end of the bolt is arranged on the bottom of the base 1, the step groove 16 and the waist type hole 15 are in communication with each other. When the base 2 needs to be moved, only the bolt at the bottom needs to be loosened, then the base 2 can be moved to the corresponding position, finally the bolt is tightened, the nut of the bolt abuts against the bottom of the step groove 16, so that the base 2 and the base 1 are fixed together.

[0021] The mounting groove 11 is arranged on the end face of the base 2 relative to the hot press mold 3, the mounting groove 11 and the sliding groove 7 are in communication with each other, the silica gel strip 10 is fixedly installed in the mounting groove 11, the downward orthogonal projection of the high temperature adhesive tape 9 is located on the silica gel strip 10, the through groove 12 for the up and down movement of the positioning block 6 is arranged on the silica gel strip 10, the high temperature adhesive tape 9, the positioning block 6 and the silica gel strip 10 together constitute a hot pressing area 20. When the product needs to be heat sealed, only one side of the product to be heat sealed is placed in the hot pressing area 20 and the side of the product to be heat sealed abuts against the side wall of the positioning block 6, the driving device 4 drives the hot press mold 3 to move downward, the hot press mold 3 pushes the positioning block 6 and the high temperature adhesive tape 9 to move downward in the process of moving downward, until the high temperature adhesive tape 9 abuts against the product, the product can be heat sealed; in addition, the silica gel strip 10 is arranged, the silica gel strip 10 itself has a certain elasticity, which can make the product and the hot press mold 3 better adhere together. Because of the machining precision and other reasons, the plane cannot be completely flat during the processing of metal, which will cause some thin products to not be well heat sealed in some positions, thereby affecting the product quality.

[0022] The sliding block 13 is connected to the base 2 in a sliding manner, and a positioning member 5 is arranged between the base 2 and the sliding block 13 (the positioning member 5 arranged between the base 2 and the sliding block 13 is the same as the positioning member 5 arranged between the base 2 and the base 1, and will not be described in detail herein), the side stopper 14 for positioning the side of the product is arranged on the sliding block 13, and the sliding block 13 and the side stopper 14 are fixed through screws. The side stopper 14 can meet the requirement of the heat sealing width limit in the horizontal direction.

[0023] With reference to Figure 1 The high-temperature adhesive tape 9 is also fixed on the hot pressing die 3, and the high-temperature adhesive tape 9 is arranged on the hot pressing die 3. On one hand, the heat of the hot pressing die 3 is not easy to dissipate, and the energy saving and constant temperature effects are achieved. On the other hand, when the product is accidentally touched by the operator during the hot pressing process, the product is not easy to be scalded.

[0024] With reference to Figure 2 The jam screw 17 is arranged between the positioning stopper 6 and the base 2, the jam screw 17 includes a screw cap 171, a rod body 172 and a threaded segment 173, the rod body 172 and the threaded segment 173 pass through the through hole 18 arranged on the positioning stopper 6, the threaded segment 173 of the jam screw 17 is threadedly connected to the base 2 after passing through the through hole 18, the counter-sunk hole 19 for hiding the screw cap 171 is arranged on the positioning stopper 6, and the diameter of the counter-sunk hole 19 is greater than that of the through hole 18. The jam screw 17 can play a guiding role during the up-down movement of the positioning stopper 6, and the screw cap 171 of the jam screw 17 can cooperate with the elastic member 8 to position the positioning stopper 6.

[0025] The implementation principle of the linear heat sealing machine in the embodiment of the present application is as follows: Figure 3As shown, a dotted line extends downward from the right side of the lower end surface of the hot pressing die 3, and the distance from the dotted line to the right side wall of the positioning block 6 is actually the width of the heat sealing. When the width of the heat sealing needs to be changed, the bolt is loosened, and the base 2 is pushed. During the movement of the base 2, the positioning block 6 also moves together. After the positioning block 6 moves, the distance from the right side wall of the positioning block 6 to the dotted line changes, so that the width of the heat sealing can be changed. When the width of the heat sealing is adjusted, the bolt is tightened to position the base 2 and the positioning block 6. Then, the side of the product that needs to be heat sealed is placed in the hot pressing area 20, and the product abuts against the side wall of the positioning block 6. In this way, the product can be positioned, and the driving device 4 is started to push the hot pressing die 3 downward. When the hot pressing die 3 abuts against the high-temperature adhesive tape 9 on the upper end surface of the positioning block 6, the high-temperature adhesive tape and the positioning block 6 are pushed downward together (during this process, the positioning block 6 moves into the sliding groove 7, and the elastic member 8 is compressed and deformed). Until the high-temperature adhesive tape 9 is heat pressed on the product. When the heat sealing is completed, the driving device 4 drives the hot pressing die 3 to reset upward. After the positioning block 6 loses the pressure of the hot pressing die 3, it also resets under the action of the elastic member 8. Subsequently, the product can be heat sealed repeatedly.

[0026] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
