However, the prior art has the following problems: the bag opening contacts the lower bar under the action of gravity, and when the conveying device moves the bag, the bag opening is easily offset due to friction, thereby affecting the accuracy of subsequent sealing.

DETAILED DESCRIPTION

[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figure 1-Figure 6 As shown, the utility model provides a hot-pressing sealing device for eliminating displacement of potato chips packaging, including a frame 1, the frame 1 is used as the basic supporting structure of the entire hot-pressing sealing device, and all other components are directly or indirectly mounted on the frame 1. A conveying device 14 for conveying potato chips packaging bags is fixed on the top of the frame 1, and a guide plate 11 for guiding the bag opening of the potato chips packaging bag is arranged on one side of the conveying device 14. The guide plate 11 guides the bag opening of the packaging bag to ensure that the bag opening maintains the correct position and direction during the conveying process, which is convenient for subsequent clamping and hot-pressing sealing. A positioning component 13 for clamping the bag opening of the packaging bag is arranged on the back of the guide plate 11 on the conveying device 14, and a hot-pressing mechanism 12 for hot-pressing and sealing the bag opening of the packaging bag is also arranged on the frame 1 in the conveying direction of the conveying device 14. The positioning component 13 clamps and positions the bag opening of the packaging bag before the packaging bag is conveyed to the hot-pressing mechanism 12, ensuring that the bag opening will not shift during the hot-pressing process. The positioning assembly 13 includes a clamping mechanism 132 for clamping the bag opening of the packaging bag and a moving mechanism 131 for reciprocating the clamping mechanism 132. The guide plate 11 includes two upper and lower bars, and a guide groove for guiding the bag opening of the packaging bag is provided between the two bars.

[0026] The packaging bag containing potato chips is placed on the conveying device 14. As the conveying device 14 moves, the packaging bag is conveyed to the position of the guide plate 11. The bag opening of the packaging bag is guided and positioned in the guide groove of the guide plate 11 to ensure that the direction and position of the bag opening are correct. When the packaging bag reaches the position of the positioning component 13, the clamping mechanism 132 clamps the bag opening of the packaging bag to ensure that the bag opening will not shift during the subsequent hot pressing process. The packaging bag is then hot-pressed and sealed at the bag opening by the hot pressing mechanism 12. The hot pressing mechanism 12 melts the material at the bag opening and tightly combines them together by heating and applying pressure to form a firm seal.

[0027] The clamping mechanism 132 includes a moving plate 1321, on which two slide bars 1323 are vertically arranged. The slide bars 1323 provide sliding tracks for two clamping plates 1324, so that the moving plate 1321 can move up and down along the slide bars 1323. The clamping mechanism 132 also includes two upper and lower clamping plates 1324 that move synchronously relative to each other. The two clamping plates 1324 are slidably connected to the slide bars 1323. The clamping mechanism 132 also includes a synchronous driving mechanism for making the two clamping plates 1324 move synchronously. The synchronous driving mechanism is responsible for driving the two clamping plates 1324 to move up and down synchronously. The synchronous driving mechanism can be a motor, a cylinder or other types of driving devices, which transmits the driving force to the clamping plates 1324 through a transmission mechanism (such as a lead screw, a gear, etc.).

[0028] When the opening of the packaging bag is inserted into the guide groove formed by the upper and lower bars, the two clamping plates 1324 will move synchronously to tightly clamp the opening of the packaging bag. As the packaging bag moves on the conveying device 14, the clamping mechanism 132 will also move synchronously to ensure that the opening of the packaging bag is stably conveyed to the hot pressing mechanism 12 for hot pressing and sealing. This design effectively eliminates the deviation of the packaging bag during the conveying process and significantly improves the accuracy of the sealing.

[0029] The synchronous drive mechanism includes two racks 1327 respectively fixed to the back of the clamping plate 1324, and the synchronous drive mechanism also includes a driving gear 1326 rotatably arranged on the moving plate 1321, the driving gear 1326 and the rack 1327 are meshed with each other, and the synchronous drive mechanism also includes a second rotating drive member 1325 fixed to the back of the moving plate 1321, and the output end of the second rotating drive member 1325 is fixedly connected to the driving gear 1326. The second rotating drive member 1325 can be a motor, a reduction motor or other types of rotating drive devices, and its output end is fixedly connected to the driving gear 1326 to ensure stable transmission of power.

[0030] When the bag mouth of the packaging bag needs to be clamped, the second rotating driving member 1325 starts to work and drives the driving gear 1326 to rotate. Since the driving gear 1326 and the rack 1327 are meshed with each other, when the driving gear 1326 rotates, it will drive the rack 1327 to move up and down. Since the rack 1327 is fixed to the back of the clamping plate 1324, the up and down movement of the rack 1327 will be converted into the up and down movement of the clamping plate 1324. Since both clamping plates 1324 are connected to the driving gear 1326 through the rack 1327, the two clamping plates 1324 can keep moving synchronously, thereby stably clamping the bag mouth of the packaging bag. During the hot pressing process, the clamping mechanism 132 remains stable to ensure that the bag mouth will not shift. After the hot pressing is completed, the second rotating driving member 1325 works again, driving the driving gear 1326 to rotate in the opposite direction, so that the clamping plate 1324 moves and releases the sealed packaging bag. Finally, the moving mechanism 131 drives the moving plate 1321 to move backward, and the clamping mechanism 132 is restored to the initial position, waiting for the arrival of the next packaging bag. Through this design, the synchronous driving mechanism can ensure that the two clamping plates 1324 always keep synchronization during the movement, thereby improving the stability and accuracy of clamping.

[0031] The moving mechanism 131 includes a support member 1311 fixed to a side of the conveying device 14 close to the guide plate 11 . The support member 1311 is also provided with a guide rail 1314 for guiding the clamping mechanism 132 . The guide rail 1314 is slidably connected to the clamping mechanism 132 .

[0032] The moving mechanism 131 also includes pulleys 1313 arranged at both ends of the support member 1311, and a belt 1315 is sleeved on the pulley 1313. The clamping mechanism 132 also includes a connecting block 1322 fixed at the bottom of the moving plate 1321, and the connecting block 1322 is fixedly connected to one of the strands of the belt 1315. A first rotating driving member 1312 is also fixed to the back of the support member 1311, and the output end of the first rotating driving member 1312 is fixedly connected to one of the pulleys 1313.

[0033] When the first rotating driving member 1312 is started, the first rotating driving member 1312 drives the pulley 1313 to rotate, thereby driving the belt 1315 to move. The movement of the belt 1315 drives the clamping mechanism 132 to move back and forth above the guide groove, thereby continuously clamping the bag mouth of the packaging bag. This design not only improves work efficiency, but also ensures the stability and continuity of the packaging bag during transportation.

[0034] The hot pressing mechanism 12 includes two upper and lower hot pressing plates 122 for hot pressing and sealing the bag opening of the packaging bag, and a temperature sensor for detecting the temperature on the hot pressing plate 122 is also provided. The hot pressing mechanism 12 also includes a telescopic driving member 121 for moving the two hot pressing plates 122, and the output end of the telescopic driving member 121 is fixedly connected to the hot pressing plate 122. The hot pressing mechanism 12 also includes a guide rod 123 provided on the conveying device 14 for guiding the hot pressing plate 122, and one end of the guide rod 123 is fixedly connected to the hot pressing plate 122.

[0035] When in use, the telescopic driving member 121 drives the hot pressing plate 122 to move downward. During the downward movement of the hot pressing plate 122, the guide rod 123 plays a guiding role to ensure that the hot pressing plate 122 keeps moving smoothly. When the hot pressing plate 122 contacts the bag opening of the packaging bag, the hot pressing plate 122 applies a certain pressure and heats to melt the bag opening material. The temperature sensor monitors the temperature of the hot pressing plate 122 in real time. If the temperature is lower than the set value, the power of the heating element is adjusted to increase the temperature of the hot pressing plate 122. When the hot pressing process is completed, the telescopic driving member 121 drives the hot pressing plate 122 to move upward to release the sealed packaging bag. Finally, the clamping mechanism 132 releases the packaging bag, and the conveying device 14 conveys it to the next processing step. Through this design, the hot pressing mechanism 12 can accurately perform hot pressing and sealing on the bag opening of the packaging bag and ensure the quality of the sealing. At the same time, the use of the temperature sensor improves the control accuracy and stability of the hot pressing process.

[0036] Working principle: When in use, first place the packaging bag containing potato chips on the conveying device 14, and insert the bag mouth of the packaging bag into the guide groove formed by the upper and lower gear bars. Then, start the second rotating driving member 1325, and the second rotating driving member 1325 drives the driving gear 1326 to rotate. Since the driving gear 1326 and the rack 1327 are meshed with each other, the rotation of the driving gear 1326 will drive the rack 1327 to move, and then the two clamping plates 1324 will move relative to each other, so as to fix the bag mouth of the packaging bag. At the same time, start the first rotating driving member 1312, and the first rotating driving member 1312 drives the pulley 1313 to rotate. The rotation of the pulley 1313 will drive the belt 1315 to move, and the movement of the belt 1315 will cause the clamping mechanism 132 to move along the guide groove. At the same time, the conveying device 14 also moves synchronously to send the packaging bag with the fixed bag mouth into the hot pressing mechanism 12. After the packaging bag reaches the hot pressing mechanism 12, the telescopic driving member 121 is started, and the telescopic driving member 121 drives the two hot pressing plates 122 to move relative to each other. After being heated, the hot pressing plates 122 perform hot pressing and sealing on the bag opening of the packaging bag. In order to ensure the sealing quality, a temperature sensor is provided inside the hot pressing plate 122 to monitor the temperature thereon in real time to avoid adverse effects on the sealing quality caused by excessive temperature.

[0037] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
