Because the upper shaping press block 220 is movably arranged on the base 100, the driving end of the first driver 210 is connected with the upper shaping press block 220, so that the first driver 210 can drive the upper shaping press block 220 to do linear reciprocating motion along the Y axis, the driving end of the second driver 310 is connected with the lower shaping press block 320, so that the second driver 310 can drive the lower shaping press block 320 to do linear reciprocating motion along the Y axis, and further, as the lower pressing groove 120 communicated with the clamping groove 110 is formed in the clamping groove 110, the lower shaping press block 320 is movably arranged in the lower pressing groove 120, and the lower shaping press block 320 and the upper shaping press block 220 are staggered, the lower pressing finger 322 of the lower shaping press block 320 can enter the lower pressing groove 120 under the driving of the second driver 310 and movably abut against the second face of the object to be heat sealed in the clamping groove 110, and when the upper shaping press block 220 and the lower shaping press block 320 are mutually close, the upper pressing finger 222 and the lower pressing finger 322 are respectively staggered and pressed tightly to enable the bag mouth to be in close, thereby ensuring that the bag mouth is in a good sealing state, and the bag mouth is not closed, and the sealing quality is better than the bag mouth is guaranteed.
2. Because the upper shaping pressing block 220 and the lower shaping pressing block 320 can close and tightly adhere to the bag mouth of the packaging bag, the operation and the structure are relatively simple, and the production efficiency is better ensured.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
