[0031] Two short fixing plates 213 are installed at both ends of the bottom plate 3 206 , and the two short fixing plates 213 are fixedly connected to the upper ring portion of the transmission belt 1 113 through a pressing plate.

[0032] The synchronous movement of the left and right slides 204 is driven by a screw transmission mechanism, which includes a transmission shaft 214. Two ends of the transmission shaft 214 are provided with two threaded sections with opposite spiral directions. The rear end face of the base plate three 206 is equipped with a left-handed nut 207 and a right-handed nut 208 that are screwed together with the corresponding screw threaded sections.

[0035] The motor 116 is mounted on the motor bracket 114 , and the motor bracket 114 is mounted on the mounting plate through the adjusting plate 102 , and is adjusted by the adjusting bolts 115 . A reinforcing plate 101 is provided between the two sides of the mounting plate and the crossbeam.

[0036] The middle parts of the corresponding end surfaces of the rear mounting plate 201 and the connecting plate 212 on the rear shaping mechanism 2 and the front mounting plate 302 on the front shaping mechanism 3 are respectively provided with dovetail grooves for convenient installation of the mold plate.

[0037] In the above structure:

[0038] like Figure 1 The frame 1 is composed of a mounting plate 100, a reinforcing plate 101, an adjusting plate 102, a cross beam 103, a lining plate 104 and a bottom plate 105. The mounting plate 100 is connected to the main machine. A guide rail 106 is installed on the two cross beams 103, and the left end slider on the guide rail 106 is connected to the rear shaping mechanism 2.

[0039] Further, if Figure 2 Described, the return shaft 107 and the driving shaft 108 are respectively installed with bearings at the two ends of the crossbeam. Two transmission wheels 109 are respectively installed at the two ends of the return shaft 107 and the driving shaft 108, and the two transmission wheels are respectively connected by a transmission belt 113.

[0040] Further, if Figure 3 As described, a driving wheel 111 is installed in the middle of the driving shaft 108. The driving wheel 111 is connected to the driving wheel 110 at the output shaft end of the motor 116 installed on the motor bracket 114 on the mounting plate 100 by a transmission belt 112. The motor bracket 114 is fixed to the mounting plate 100 with bolts and is tensioned and adjusted with an adjusting bolt 115 and the adjusting plate 102.

[0041] like Figure 1 , Figure 2 , Figure 4 As described above, the rear shaping mechanism 2 is composed of a vertical plate 200, a rear mounting plate 201, a bottom plate 202, etc. The bottom plate 202 is connected to the guide rail 106 on the frame 1 by two sliders. Figure 2 Described, two short fixed plates 213 are installed at the two ends of the bottom plate 202. The two short fixed plates 213 are fixed with the upper ring part of the transmission belt 1 113 by the pressing plate 306 and move left and right with the transmission belt 1 113.

[0042] Further Figure 2 , Figure 4As described above, two guide rails 203 are installed on the rear mounting plate 201, and two sliders 1 205 are installed on the two guide rails 203 respectively. The two sliders 1 205 are respectively installed with left and right slides 204 through the bottom plate 3 206. The left and right slides 204 are connected to the transmission shaft 214 by a left-hand nut 207 and a right-hand nut 208 respectively. The transmission shaft 214 is connected to the vertical plate 1 200 by a sleeve. A driven wheel 218 is installed at the left end of the transmission shaft 214, and the driven wheel 218 is connected to the driving wheel 216 installed at the output shaft end of the motor 215 at the lower end of the vertical plate by a transmission belt 217. The rotation of the motor 215 drives the transmission shaft 214 to rotate, and the rotation of the transmission shaft 214 drives the left and right slides 204 to move toward or oppositely.

[0043] Further Figure 2 As described, left and right shaping cylinders 211 are installed on the fixing plate 209 of the left and right slides 204, and connecting plates 212 are installed at the guide rod ends of the left and right shaping cylinders 211, and the connecting plates can be installed with mold plates. Guide pillars 210 are installed on both sides of the left and right shaping cylinders 211, and the front ends of the guide rods 210 are connected to the connecting plates 212 to keep the connecting plates 212 moving horizontally.

[0044] like Figure 1 , Figure 2 As described above, the front shaping mechanism 3 is composed of a bottom plate 4 300, a vertical plate 2 301, a front mounting plate 302, etc. Two sliders 2 307 are mounted on the bottom plate 4 300 and connected to the guide rail 106 on the bottom frame 1. Long fixed plates 305 are mounted at both ends of the bottom plate 4 300, and the lower end of the long fixed plate 305 is connected to the lower ring of the transmission belt 113 by a pressing plate 306 and moves left and right with the transmission belt 113.

[0045] Further Figure 1 As described above, the front end of the second vertical plate 301 is fixed to the front mounting plate 302 by means of a buffer pad 303 and bolts and nuts, and a vibrator 304 is installed at the rear side of the front mounting plate 302 .

[0046] like Figure 1As described, during operation, the motor 116 rotates clockwise, and the drive wheel 110 at the motor output shaft end also rotates clockwise. The drive wheel 110 rotates to drive the transmission belt 112 to rotate, and the transmission belt 112 drives the driving wheel 111 to rotate, and the driving wheel 111 drives the driving shaft 108 and the driving wheels 109 at both ends to rotate. The driving wheel 109 drives the two driving wheels installed on the return shaft 107 to rotate through the two driving belts 113. At this time, the rear shaping mechanism 2 moves to the right because it is connected to the upper ring part of the transmission belt 113, and the front shaping mechanism 3 moves to the left because the front shaping mechanism 3 is connected to the lower ring part of the transmission belt 113. On the contrary, when the motor 116 rotates counterclockwise, the rear shaping mechanism 2 moves to the left and the front shaping mechanism 3 moves to the right. In this way, the front and rear shaping of the six-sided packaging is completed. Similarly, the left and right carriages 204 shrink and open oppositely under the drive of the motor 215. Its movement sets the width of the mold based on the readings of a code reader 219 mounted on the output shaft end of the motor 215 and a sensor 221 fixed on a bracket 220 of the rear mounting plate 201.

[0047] like Figure 2 As described, during operation, the front, rear, left, and right molds are inserted into the dovetail groove and the lower mold mechanism 4. As further described in the figure, the filled material is loaded from the upper opening of the shaping mechanism into a cavity composed of a rear shaping mechanism, a front shaping mechanism, and a lower mold mechanism. At this time, the front and rear shaping mechanisms are put together under the drive of the motor 116. At the same time, the cylinder guide rods on the left and right slides extend out, and the lower mold mechanism pushes upward to integrate the material into a six-sided "brick" shape and evacuate it. After evacuation, a sealing mechanism is used for sealing. After sealing is completed, the motor 116 is reversed to move the front and rear shaping mechanisms in opposite directions, and at the same time, the cylinder guide rods on the left and right slides contract to loosen the material to complete the material vacuuming action.
