[0021] As shown in the drawings, Figure 3 , Figure 4 and Figure 6As shown, the moving plate 201 is in contact with the inner wall of the fixed plate 500, one end of the reset spring 212 is fixedly connected with the outer wall of the control plate 211, and the other end of the reset spring 212 is fixedly connected with the inner wall of the fixed plate 500; the control plate 211 is slidingly connected in the inner wall of the fixed plate 500, the guide plate 209 is slidingly connected with the inner wall of the fixed plate 500, and the fixed rod 207 is slidingly connected with the inner wall of the fixed plate 500.

[0022] With the above scheme: the fixed rod 207 can only move horizontally in the fixed plate 500, and the moving plate 201 can move horizontally synchronously with the fixed rod 207, and can also move vertically on the outer wall of the fixed rod 207; the food bag can be placed on the bottom plate 202, and the food bag can be fixed by moving the clamping plate 203 downward to clamp the side edges of the food bag, and the clamping plate 203 and the bottom plate 202 are in contact with the food bag to avoid being provided with rubber strips, which can improve the friction between the clamping plate 203 and the food bag, avoid the food bag from falling off during stretching, and ensure the clamping effect; under normal circumstances, the control plate 211 is above the inner wall of the fixed plate 500 due to the elastic force of the reset spring 212, and a group of guide plates 209 are arranged on both sides of the fixed plate 500, which can be used to drive the moving plate 201 to move.

[0023] As shown in Figure 3 , Figure 4 and Figure 6 , the inner wall of the clamping plate 203 is elastically connected with a wedge-shaped block 205 through a connecting spring 204, the outer wall of the moving plate 201 is provided with a groove 206, and the outer wall of the guide plate 209 is provided with a guide groove 210.

[0024] With the above scheme: the clamping plate 203 can move up and down on the outer wall of the moving plate 201, and the position of the clamping plate 203 can be fixed through the clamping of the wedge-shaped block 205 and the groove 206, the groove 206 is provided with two groups of upper and lower grooves, and when the wedge-shaped block 205 is clamped with the upper groove 206, the distance between the clamping plate 203 and the bottom plate 202 is larger, the food bag can be placed between them, and after the clamping plate 203 is moved downward to be in contact with the outer wall of the food bag, the clamping plate 203 is clamped with the lower groove 206 through the wedge-shaped block 205, so that the clamping effect of the clamping plate 203 and the bottom plate 202 on the food bag can be maintained; the guide groove 210 is provided with an inclined line segment and a straight line segment, in the initial state, the control plate 211 and the guide plate 209 are in the upper position, the convex block 208 is in contact with the bottom end of the inclined line segment of the guide groove 210, and when the punch module 700 is pressed, the convex block 208 will move along the inner wall of the guide groove 210, and under the guide action, the moving plate 201 is driven to move horizontally through the fixed rod 207.

[0025] As shown in Figure 3 , Figure 4 and Figure 6As shown, one end of the connecting spring 204 is fixedly connected with the outer wall of the wedge block 205, the other end of the connecting spring 204 is fixedly connected with the inner wall of the clamping plate 203, the wedge block 205 is slidingly connected in the inner wall of the clamping plate 203, the wedge block 205 is clamped with the groove 206, and the protrusion 208 is in contact with the inner wall of the guide groove 210.

[0026] With the above scheme: the arc surface of the wedge block 205 always faces downward, when the clamping plate 203 is pressed downward, the arc surface of the wedge block 205 is extruded by the inner wall of the groove 206, the wedge block 205 moves into the inner wall of the clamping plate 203, and the connecting spring 204 is compressed, when the clamping plate 203 moves downward to the position corresponding to the wedge block 205 and the lower groove 206, the wedge block 205 is ejected from the lower groove 206 under the elastic force of the connecting spring 204, and the food bag is fixed; when the food bag needs to be taken out, the operator can manually press the wedge block 205 to make it out of contact with the lower groove 206, so as to release the limiting of the clamping plate 203 and move it upward to separate it from the food bag and take it out.

[0027] As shown in Figure 3 , Figure 5 and Figure 6 , the lifting mechanism includes an inclined block 301, the outer wall of the inclined block 301 is fixedly connected with a stop rod 302, the outer wall of the inclined block 301 is slidingly connected with a sliding rod 303, and the outer wall of the sliding rod 303 is hinged with a lifting plate 305 through a hinge rod 304.

[0028] With the above scheme: the lifting mechanism is used to move the food bag upward during the stamping process, so as to better avoid the adhesion of waste and food bag; during the stamping process, the stamping module 700 drives the control plate 211 and the guide plate 209 to move downward, the guide plate 209 extrudes the stop rod 302 when moving downward, so as to drive the inclined block 301 to move downward, the sliding rod 303 is moved to the middle through the extrusion of the inclined block 301, the hinge rod 304 is turned upward, the lifting plate 305 drives the bottom plate 202 to move vertically upward, and the food bag is moved upward as a whole.

[0029] As shown in Figure 3 , Figure 5 and Figure 6 , the inclined block 301 and the inner wall of the fixed plate 500 and the base 100 are slidingly connected, the sliding rod 303 is slidingly connected with the inner wall of the base 100, the two ends of the hinge rod 304 are respectively hinged with the outer walls of the lifting plate 305 and the sliding rod 303, and the lifting plate 305 is slidingly connected with the bottom end outer wall of the moving plate 201.

[0030] Using the above scheme: Under normal conditions, the slide bar 303 is in contact with the bottom end of the inclined surface of the inclined block 301. When the inclined block 301 moves down, its inclined surface will squeeze the slide bar 303. Since the slide bar 303 can only move laterally, the inclined blocks 301 on both sides will cause the corresponding slide bars 303 to move towards the middle at the same time, pushing the hinge rod 304 and its connected end to move synchronously. The other end of the hinge rod 304 is hinged to the bottom end of the lifting plate 305. Since the lifting plate 305 is connected to the moving plate 201, and the moving plate 201 can move vertically, the hinge rod 304 will flip and lift the lifting plate 305, causing the moving plate 201 and the fixed food bag to move upward synchronously. The stamping module 700 moves down until the stamping head contacts the base 100. After punching, the upward movement of the food bag can make the stamping head press down on the waste material, so that the waste material is completely separated from the food bag. Therefore, it is more convenient as operators do not need to manually clean the sticky waste material.

[0031] like Figures 3 to 7 As shown, the connecting mechanism 400 includes a connecting block 401. A trapezoidal block 405 is elastically connected to the inner wall of the connecting block 401 via a telescopic spring 404. A connecting rod 403 is slidably connected to the inner wall of the connecting block 401. A limit block 402 is slidably connected to the inner wall of the connecting block 401. A limit groove 406 is formed on the outer wall of the stamping module 700. A pressure plate 213 is fixedly connected to the outer wall of the connecting block 401.

[0032] The above solution is adopted: the connecting mechanism 400 is used to facilitate quick and easy replacement of the stamping module 700, so as to select the appropriate stamping module 700 for punching according to the requirements; the outer wall of the connecting block 401 is provided with two sets of pressure plates 213. When it moves down to punch, the pressure plates 213 will contact the control plate 211 and drive the control plate 211 to move down synchronously. The control plate 211 is used to drive the stretching mechanism 200 and the lifting mechanism; when the control plate 211 moves down, it drives the guide plate 209 to move synchronously. The guide groove 210 pushes the protrusion 208 to move to both sides. The protrusion 208 moves along the inclined segment of the guide groove 210. The protrusion 208 drives the corresponding moving plate 201 to move laterally to both sides through the fixing rod 207, so as to stretch the food bag; when the control plate 211 continues to be under pressure When moving downwards, after the protrusion 208 moves into the straight section of the guide groove 210, the moving plate 201 maintains its current position. At this time, the guide plate 209 moves downwards and presses down the stop bar 302, causing the inclined block 301 to move downwards synchronously. This causes the lifting plate 305 to move upwards, lifting the moving plate 201 and the fixed food bag. This process is carried out simultaneously with the downward movement of the stamping module 700. When the stamping head is in contact with the base 100, the stamping head penetrates the food bag after it has moved upwards, thus separating the waste from the food bag. When the stamping module 700 moves upwards to reset, the reset spring 212 drives the control plate 211 and the guide plate 209 to reset. The protrusion 208 moves in the opposite direction along the inner wall of the guide groove 210, and through the fixed rod 207, it drives the base plate 202 back to the initial state. The entire lifting mechanism resets synchronously.

[0033] like Figure 7 As shown, the connecting block 401 is fixedly connected to the movable end of the cylinder on the top plate 600, one end of the telescopic spring 404 is fixedly connected to the outer wall of the trapezoidal block 405, and the other end of the telescopic spring 404 is fixedly connected to the inner wall of the connecting block 401; the trapezoidal block 405 is slidably connected in the inner wall of the connecting block 401, one end of the connecting rod 403 is slidably connected to the outer wall of the trapezoidal block 405, and the other end of the connecting rod 403 is fixedly connected to the outer wall of the limiting block 402; the pressure plate 213 is in contact with the outer wall of the control plate 211.

[0034] Using the above scheme: When the stamping module 700 is installed in the connecting block 401, it can be fixed by the snap-fit ​​between the limiting block 402 and the limiting groove 406. The front end of the limiting block 402 is wedge-shaped, with the arc surface facing down, and the straight surface contacts the inner wall of the limiting groove 406, providing a supporting effect. Both sets of connecting rods 403 are in contact with the short side inclined surface of the trapezoidal block 405. The outer wall of the trapezoidal block 405 is flush with the outer wall of one side of the connecting block 401. The operator can manually press the trapezoidal block 405 inward, and the telescopic spring 404 will contract under force. The inclined surface will squeeze the connecting rod 403. The connecting rod 403 can only move laterally, so it will drive the corresponding limiting block 402 to move synchronously to both sides. Once the limiting groove 406 disengages, the stamping module 700 can be removed. When installing the stamping module 700, it can be moved upwards into the inner wall of the connecting block 401. Its outer wall presses against the arc surface of the limiting block 402, causing it to move to both sides. The connecting rod 403 moves synchronously and drives the trapezoidal block 405 to move inwards, compressing the telescopic spring 404. When the stamping module 700 moves to the position where the limiting block 402 corresponds to the limiting groove 406, the telescopic spring 404 drives the trapezoidal block 405 to reset. The connecting rod 403 and the limiting block 402 reset synchronously, thus completing the fixing of the stamping module 700. It is more convenient and faster to disassemble and install without the need for operators to manually rotate the bolts.

[0035] Working principle and usage process of this invention: The operator can stack the food bags to be punched flat on the two bottom plates 202 and manually press down the clamping plate 203. When the clamping plate 203 is in contact with the surface of the food bag, the wedge block 205 pops out and engages with the groove 206 below, thus fixing the two sides of the food bag. The rubber strip between the clamping plate 203 and the bottom plate 202 increases the friction and prevents the food bag from slipping when stretched.

[0036] After the fixing is completed, the operator can start the stamping switch. The moving end of the cylinder drives the stamping module 700 to move down. The pressure plate 213 on the outer wall of the connecting block 401 first contacts the control plate 211 in the fixed plate 500. As the cylinder continues to extend, the pressure plate 213 pushes the control plate 211 and the guide plate 209 to move down, triggering subsequent stretching and lifting.

[0037] When the guide plate 209 moves down, the guide groove 210 pushes the protrusion 208. The protrusion 208 drives the fixing rod 207 to move laterally along the inner wall of the fixing plate 500. The fixing rod 207 simultaneously pulls the moving plate 201 to unfold to both sides, and the distance between the two moving plates 201 increases until the protrusion 208 slides into the straight section of the guide groove 210. At this time, the moving plate 201 stops moving laterally, and the food bag is stretched to a taut state to avoid hole displacement or hole edge tearing due to wrinkles during stamping.

[0038] As the stamping module 700 continues to move downward, the guide plate 209 continues to move downward with the control plate 211. The protrusion 208 stops in the straight section of the guide groove 210. The moving plate 201 is fixed in the lateral position. The bottom end of the guide plate 209 presses down the stop bar 302, which drives the inclined block 301 to move downward synchronously. Its inclined surface squeezes the slide bar 303, and the slide bar 303 moves laterally to the middle, which drives the hinge rod 304 to flip upward and lift the lifting plate 305. When the lifting plate 305 moves upward, it simultaneously drives the moving plate 201, the base plate 202 and the fixed food bag to move vertically upward until the stamping head of the stamping module 700 is in contact with the surface of the base 100.

[0039] In this state, the food bag has moved up a certain distance, and the punch head completely penetrates the food bag. The waste material is pressed firmly onto the base 100 by the punch head and completely separated from the food bag, avoiding the problem of waste material sticking to the food bag and requiring manual cleaning by the operator, making it more convenient to use.

[0040] After stamping is completed, the moving end of the cylinder retracts, the stamping module 700 resets upward, the pressure plate 213 disengages from the control plate 211, the tensioning mechanism 200 resets from the lifting mechanism, the operator can press the wedge block 205 to disengage it from the groove 206 below, pull up the clamping plate 203, and take out the stamped food bag.

[0041] When it is necessary to adapt to food bags with different hole diameters and numbers, the operator can press the trapezoidal block 405 inward to compress the telescopic spring 404. The inclined surface of the trapezoidal block 405 presses against the connecting rods 403 on both sides, causing the limiting block 402 to move to both sides and disengage from the limiting groove 406 of the stamping module 700. The stamping module 700 can then be removed from the connecting block 401. When installing the matching stamping module 700, align it with the inner wall of the connecting block 401 and push it upward. The limiting block 402 will then engage with the limiting groove 406, completing the fixation of the stamping module 700. The next round of stamping can then be started.
