[0028] The above technical solution has the following advantages or beneficial effects:

[0029] The bag making machine provided by the present utility model includes a feeding assembly, a sealing assembly, a cutting assembly and a discharging assembly;

[0030] In order to realize the process flow of processing the bag body, the sealing assembly and the cutting assembly are arranged between the feeding assembly and the discharging assembly, and the sealing assembly is close to the feeding assembly. When the material to be processed enters from the feeding assembly, first the sealing assembly seals the single side edge of the material, and then the cutting assembly divides the material, so as to process the material into an independent bag body and leave from the discharging assembly; the sealing assembly and the cutting assembly can process and cut the material during the process of the material entering and leaving, realizing the automatic processing of the bag body;

[0031] In order to enable the material to actively enter the bag making machine, the feeding assembly includes a first traction shaft, a first roller shaft, a first vertical moving mechanism and a first driving mechanism. The first traction shaft is mainly used to cooperate with the first roller shaft to press and convey the entered material to be processed. Therefore, the first traction shaft is arranged above the first roller shaft, and the first vertical moving mechanism can drive the first traction shaft to move in the vertical direction. When the first vertical moving mechanism drives the first traction shaft to move upward, a gap can be formed between the first traction shaft and the first roller shaft for the material to enter. After the material is placed in the gap, the first traction shaft is driven downward by the first vertical moving mechanism, so that the material is pressed between the first traction shaft and the first roller shaft. In order to enable the bag making machine to continuously process the material and allow the material to continue to move forward, the first traction shaft is rotatable, the first roller shaft is rotatable, and the first driving mechanism drives the first roller shaft to rotate. When the material is pressed between the first traction shaft and the first roller shaft, the first driving mechanism The mechanism drives the first roller to rotate, and the material will move forward following the rotation of the first roller. The rotation of the first roller drives the first traction shaft to rotate to prevent the material from being stuck between the first traction shaft and the first roller. The first traction shaft and the first roller jointly feed the material into the bag making machine; further, when the axis of the first traction shaft and the axis of the first roller are set on the same vertical plane, the first traction shaft is driven by the first vertical moving component to move downward, and the first traction shaft can easily contact the arc surface of the first roller, thereby better producing a clamping effect to prevent the material from escaping from the feeding component; when the material enters the gap between the first traction shaft and the first roller, the first traction shaft is controlled by the first vertical moving mechanism to move downward, and cooperates with the first roller to clamp the material. Compared with the prior art that fixes the position of the roller, the bag making machine avoids the situation where the material is difficult to keep in a clamped state due to uneven thickness of the material, thereby avoiding affecting the material transmission rate, thereby improving the production efficiency of the bag body;

[0032] When the material is processed by the sealing component and the cutting component, it needs to leave the bag-making machine in time, otherwise it will cause blockage at the discharge port of the bag-making machine. To ensure that the bag formed by the material processing can leave from the discharge component, therefore, the discharge component includes a second traction shaft, a second roller shaft, a second vertical movement mechanism and a second driving mechanism; to prevent the bag from leaving the bag-making machine due to the influence of the rotation of the second roller shaft, therefore, the second traction shaft is arranged above the second roller shaft, so that the second vertical movement mechanism can drive the second traction shaft to move in the vertical direction. After the bag is processed by the sealing component and the cutting component, it is sent to the second roller shaft by the feeding component. Through the second vertical movement mechanism, the second traction shaft can be controlled to lift upward. At this time, a large gap is formed between the second traction shaft and the second roller shaft, and the bag can enter this gap; when the bag enters the gap between the second traction shaft and the second roller shaft, the second vertical movement mechanism is used to control the second traction shaft to move downward, so that the second traction shaft and the second roller shaft clamp the bag. At this time, the bag cannot easily leave from this gap, and the position of the bag can be controlled more precisely; further, in order to push the bag to move and leave the bag-making machine, the second traction shaft is rotatable, the second roller shaft is rotatable, and the second driving mechanism drives the second roller shaft to rotate. When the bag is clamped between the second traction shaft and the second roller shaft, at this time the second driving mechanism drives the second roller shaft to rotate, and the bag will move forward following the rotation of the second roller shaft. The rotation of the second roller shaft drives the rotation of the second traction shaft, preventing the bag from being stuck between the second traction shaft and the second roller shaft. The second traction shaft and the second roller shaft jointly send the bag out of the bag-making machine; further, when the axis of the second traction shaft and the axis of the second roller shaft are arranged in the same vertical plane, the second traction shaft is driven by the second vertical movement component to move downward, and the second traction shaft can easily contact the arc surface of the second roller shaft, so as to better generate a clamping effect and prevent the material from separating from the discharge component; by using the method of clamping the bag by the second traction shaft and the second roller shaft and driving the bag away from the bag-making machine by the rotation of the second roller shaft, it is possible to avoid blocking the discharge port of the bag-making machine when the bag has no guidance or no thrust, and further avoid affecting the subsequent production;

[0033] Furthermore, in order to make the entry direction of the material and the output direction of the bag consistent, the axis of the first traction shaft is parallel to the axis of the second traction shaft, which is more conducive to the transportation and processing of the material.

[0043] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not limited to the present utility model.

[0044] Embodiment 1:

[0045] As Figures 1 - 3 shown, a bag making machine provided by Embodiment 1 of the present utility model includes a feeding component 1, a sealing component 2, a cutting component 3, and a discharging component 4;

[0046] The sealing component 2 and the cutting component 3 are located between the feeding component 1 and the discharging component 4;

[0048] The discharging assembly 4 includes a second traction shaft 41, a second roller shaft 42, a second vertical movement mechanism 43 and a second driving mechanism 44; the second traction shaft 41 is located above the second roller shaft 42; the second vertical movement mechanism 43 can drive the second traction shaft 41 to move in the vertical direction; the second traction shaft 41 is rotatable; the second roller shaft 42 is rotatable; the axis of the second traction shaft 41 and the axis of the second roller shaft 42 are in the same vertical plane; the second driving mechanism 44 can drive the second roller shaft 42 to rotate;

[0049] The axis of the first traction shaft 11 is parallel to the axis of the second traction shaft 41.

[0050] When using the bag making machine provided in Embodiment 1 of the present utility model, two layers of materials are stacked, and the two sides perpendicular to the axis of the first traction shaft 11 of the materials have been preliminarily processed to be sealed when the materials enter the feeding assembly 1;

[0051] Let the materials enter from the feeding assembly 1. Specifically, the materials need to enter from the gap between the first traction shaft 11 and the first roller shaft 12. The first vertical movement assembly 13 is used to lift the first traction shaft 11 upward to form a larger gap between the first traction shaft 11 and the first roller shaft 12, and the materials to be processed are placed in this gap; the first vertical movement assembly 13 is used to move the first traction shaft 11 downward so that it and the first roller shaft 12 jointly press the materials in the gap; the first driving mechanism 14 is used to control the first roller shaft 12 to rotate, driving the first traction shaft 11 to rotate. At this time, the materials clamped by the first traction shaft 11 and the first roller shaft 12 can continuously convey the materials to be processed in the rotation direction of the first roller shaft 12;

[0052] One side of the materials fed by the feeding assembly 1 parallel to the axis of the first traction shaft 11 is sealed by the sealing assembly 2. Taking the direction of the discharging assembly 4 relative to the feeding assembly 1 as the front of the materials, the materials behind the sealed end are divided by the cutting assembly 3 to form independent bags;

[0053] The bags leave from the discharging assembly 4. Specifically, the bags leave from the gap between the second traction shaft 41 and the second roller shaft 42. The second vertical movement assembly 43 is used to lift the second traction shaft 41 upward to form a larger gap between the second traction shaft 41 and the second roller shaft 42, and the bags slide above the second roller shaft 42; the second vertical movement assembly 43 is used to move the second traction shaft 41 downward so that it and the second roller shaft 42 jointly press the bags in the gap; the second driving mechanism 44 is used to control the second roller shaft 42 to rotate, driving the second traction shaft 41 to rotate. At this time, the bags clamped by the second traction shaft 41 and the second roller shaft 42 can be removed from the bag making machine.

[0054] The bag making machine provided in Embodiment 1 of the present utility model includes a feeding assembly 1, a sealing assembly 2, a cutting assembly 3 and a discharging assembly 4;

[0055] In order to realize the process-oriented processing of the bag body, the sealing component 2 and the cutting component 3 are arranged between the feeding component 1 and the discharging component 4, and the sealing component 2 is close to the feeding component 1. When the material to be processed enters from the feeding component 1, the sealing component 2 first seals the single side of the material, and then the cutting component 3 divides the material, so that the material is processed into an independent bag body, and leaves from the discharging component 4; the sealing component 2 and the cutting component 3 can process and cut the material in the process between the material entering and leaving, so as to realize the automatic processing of the bag body;

[0056] In order to enable the material to actively enter the bag making machine, the feeding assembly 1 includes a first traction shaft 11, a first roller shaft 12, a first vertical moving mechanism 13 and a first driving mechanism 14. The first traction shaft 11 is mainly used to cooperate with the first roller shaft 12, so as to compact and convey the incoming material to be processed. Therefore, the first traction shaft 11 is arranged above the first roller shaft 12, and the first vertical moving mechanism 13 can drive the first traction shaft 11 to move in the vertical direction. When the first vertical moving mechanism 13 drives the first traction shaft 11 to move upward, A gap can be formed between the first traction shaft 11 and the first roller 12 for the material to enter. After the material is placed in the gap, the first traction shaft 11 is driven downward by the first vertical moving mechanism 13, so that the material is pressed between the first traction shaft 11 and the first roller 12. In order to enable the bag making machine to continuously process the material and allow the material to continue to move forward, the first traction shaft 11 is rotated, the first roller 12 is rotated, and the first driving mechanism 14 drives the first roller 12 to rotate. When the material is pressed between the first traction shaft 11 and the first roller 12, The first driving mechanism 14 drives the first roller 12 to rotate, and the material will move forward following the rotation of the first roller 12. The rotation of the first roller 12 drives the first traction shaft 11 to rotate to prevent the material from being stuck between the first traction shaft 11 and the first roller 12. The first traction shaft 11 and the first roller 12 jointly feed the material into the bag making machine; further, when the axis of the first traction shaft 11 and the axis of the first roller 12 are set on the same vertical plane, the first traction shaft 11 is driven by the first vertical moving component 13 to move downward, and the first traction shaft 11 can be easily The first roller 12 is in contact with the arc surface of the first roller 12, thereby better producing a clamping effect to prevent the material from escaping from the feeding assembly 1; when the material enters the gap between the first traction shaft 11 and the first roller 12, the first traction shaft 11 is controlled by the first vertical moving mechanism 13 to move downward, and cooperates with the first roller 12 to clamp the material. Compared with the prior art that fixes the position of the roller, the bag making machine avoids the situation that the material is difficult to keep in a clamped state due to uneven thickness of the material, thereby avoiding affecting the material transmission rate, thereby improving the production efficiency of the bag body;

[0057] After the material is processed by the sealing assembly 2 and the cutting assembly 3, it needs to leave the bag making machine in time. Otherwise, it will cause blockage at the discharge port of the bag making machine. To ensure that the bag formed by the material processing can leave from the discharge assembly 4, therefore, the discharge assembly 4 includes a second traction shaft 41, a second roller shaft 42, a second vertical moving mechanism 43 and a second driving mechanism 44. To prevent the bag from leaving the bag making machine due to the influence of the rotation of the second roller shaft 42, therefore, the second traction shaft 41 is arranged above the second roller shaft 42, so that the second vertical moving mechanism 43 can drive the second traction shaft 41 to move in the vertical direction. After the bag is processed by the sealing assembly 2 and the cutting assembly 3, it is sent to the second roller shaft 42 by the feeding assembly 1. Through the second vertical moving mechanism 43, the second traction shaft 41 can be controlled to lift upward. At this time, a large gap is formed between the second traction shaft 41 and the second roller shaft 42, and the bag can enter this gap. When the bag enters the gap between the second traction shaft 41 and the second roller shaft 42, the second traction shaft 41 is controlled to move downward through the second vertical moving mechanism 43, so that the second traction shaft 41 and the second roller shaft 42 clamp the bag tightly. At this time, the bag cannot easily leave from this gap, and the position of the bag can be controlled more precisely. Further, to be able to push the bag to move and leave the bag making machine, the second traction shaft 41 is rotatable, the second roller shaft 42 is rotatable, and the second driving mechanism 44 drives the second roller shaft 42 to rotate. When the bag is clamped between the second traction shaft 41 and the second roller shaft 42, at this time, the second driving mechanism 44 drives the second roller shaft 42 to rotate, and the bag will move forward following the rotation of the second roller shaft 42. The rotation of the second roller shaft 42 drives the rotation of the second traction shaft 41, preventing the bag from being stuck between the second traction shaft 41 and the second roller shaft 42. The second traction shaft 41 and the second roller shaft 42 jointly send the bag out of the bag making machine. Further, when the axis of the second traction shaft 41 and the axis of the second roller shaft 42 are arranged in the same vertical plane, the second traction shaft 41 is driven by the second vertical moving assembly 43 to move downward, and the second traction shaft 41 can easily contact the arc surface of the second roller shaft 42, so as to better generate a clamping effect and prevent the material from detaching from the discharge assembly 4. By using the method of clamping the bag by the second traction shaft 41 and the second roller shaft 42 and driving the bag away from the bag making machine by the rotation of the second roller shaft 42, it is possible to avoid blocking the discharge port of the bag making machine when the bag has no guidance or thrust, and further avoid affecting the subsequent production.

[0058] Furthermore, to enable the entering direction of the material and the output direction of the bag to be consistent, the axis of the first traction shaft 11 is parallel to the axis of the second traction shaft 41, which is more conducive to the transportation and processing of the material.

[0059] Such as Figures 2 - 3 and Figures 6 - 7As shown in the figure, the bag making machine provided by Embodiment 1 of the present utility model preferably further includes a flat plate 5 for receiving materials and a fixed bracket 6 in order to facilitate the transportation and processing of materials. The flat plate 5 is horizontally fixed on the fixed bracket 6. In order to seal and cut the materials, the sealing assembly 2 and the cutting assembly 3 are arranged above the flat plate 5. Further, in order to simplify the processing flow of the materials, the feeding assembly 1 and the discharging assembly 4 are arranged on both sides of the flat plate 5, so that the first roller shaft 12 and the second roller shaft 42 are located on both sides of the flat plate 5. At this time, the material inlet and the bag body outlet are in a straight line, which is convenient for the flow processing method. Further still, the highest point of the second roller shaft 42 is flush with the flat plate 5, so that the flat plate 5 can more stably receive the materials entering from the feeding assembly 1 and enable the processed bag body to leave from the discharging assembly 4.

[0060] The feeding assembly 1 further includes two first bearings 15 and two second bearings 16.

[0061] In order to enable the first traction shaft 11 to rotate, both ends of the first traction shaft 11 are respectively sleeved in the first bearings 15, and the first traction shaft 11 is fixed to the inner rings of the first bearings 15, so that the first traction shaft 11 can still rotate under the fixation of the outer rings of the first bearings 15, avoiding that when the first traction shaft 11 cooperates with the first roller shaft 12 to clamp the material, the first traction shaft 11 cannot rotate and the material is stuck between the first traction shaft 11 and the first roller shaft 12.

[0062] In order to enable the first roller shaft 12 to rotate, both ends of the first roller shaft 12 are respectively sleeved in the second bearings 16, and the first roller shaft 12 is fixed to the inner rings of the second bearings 16, so that the first roller shaft 12 can still rotate under the fixation of the outer rings of the second bearings 16, avoiding that the first roller shaft 12 cannot be driven and rotated by the first driving mechanism 14.

[0063] In order to move the first traction shaft 11 vertically through the first vertical movement mechanism 13, the first vertical movement mechanism 13 includes two first cylinders 131. The first cylinders 131 are fixed to the fixed bracket 6. The first cylinders 131 are located above the flat plate 5. The telescopic shafts of the first cylinders 131 face downward. The first cylinders 131 are located above the first traction shaft 11. One first cylinder 131 corresponds to one first bearing 15. The telescopic shaft of the first cylinder 131 is fixed to the outer ring of the first bearing 15. At this time, the up and down movement of the first traction shaft 11 can be controlled by controlling the telescopic movement of the telescopic shaft of the first cylinder 131. When the telescopic shaft of the first cylinder 131 extends, the first traction shaft 11 moves downward, and then presses the material against the first roller shaft 12. When the telescopic shaft of the first cylinder 131 retracts, the first traction shaft 11 moves upward, creating a gap between the first traction shaft 11 and the first roller shaft 12. Arranging the first cylinders 131 at both ends of the first traction shaft 11 can keep the first traction shaft 11 balanced during the lifting process;

[0064] In order to rotate the first roller shaft 12 through the first drive mechanism 14, the outer ring of the second bearing 16 is fixed to the fixed bracket 6. The first drive mechanism 14 includes a first pulley 141, a first driving wheel, a first motor, and a first belt. The first driving wheel is fixed to the output shaft of the first motor. The axis of the first driving wheel coincides with the axis of the output shaft of the first motor, so that the rotation speed of the first driving wheel is the same as the rotation speed of the output shaft of the first motor. The first pulley 141 is fixed to one end face of the first roller shaft 12. The axis of the first pulley 141 coincides with the axis of the first roller shaft 12, so that the rotation speed of the first pulley 141 is the same as the rotation speed of the first roller shaft 12. When the cross-section of the first pulley 141 and the cross-section of the first driving wheel are in the same plane, the inner ring of the first belt simultaneously contacts the arc surface of the first pulley 141 and the arc surface of the first driving wheel, and when the first belt is in a taut state, the rotational force generated by the output shaft of the first motor is transmitted by the first driving wheel through the first belt. The first belt drives the first pulley 141 to rotate, thereby rotating the first roller shaft 12 fixed with the first pulley 141. Here, the way of driving the first pulley 141 and the first driving wheel by the first belt is the same as the way of driving the driving wheel and the driven wheel by the belt recorded in Chinese Patent Application No. 201720041003.9;

[0065] The discharging assembly 4 further includes two third bearings 45 and two fourth bearings 46;

[0066] In order to enable the second traction shaft 41 to rotate, both ends of the second traction shaft 41 are respectively sleeved in the third bearing 45, and the second traction shaft 41 is fixed to the inner ring of the third bearing 45, so that the second traction shaft 41 can still rotate under the condition that the outer ring of the third bearing 45 is fixed, avoiding that when the second traction shaft 41 cooperates with the second roller shaft 42 to clamp the bag body, the bag body is stuck between the second traction shaft 41 and the second roller shaft 42 due to the inability of the second traction shaft 41 to rotate;

[0067] In order to enable the second roller shaft 42 to rotate, both ends of the second roller shaft 42 are respectively sleeved in the fourth bearing 46, and the second roller shaft 42 is fixed to the inner ring of the fourth bearing 46, so that the second roller shaft 42 can still rotate under the condition that the outer ring of the fourth bearing 46 is fixed, avoiding that the second roller shaft 42 cannot be driven and rotated by the second driving mechanism 44;

[0068] In order to realize the vertical movement of the second traction shaft 41 by the second vertical movement mechanism 43, the second vertical movement mechanism 43 includes two second cylinders 431. The second cylinders 431 are fixed to the fixed bracket 6, the second cylinders 431 are located above the flat plate 5, the telescopic shafts of the second cylinders 431 face downward, the second cylinders 431 are located above the second traction shaft 41, one second cylinder 431 corresponds to one third bearing 45, and the telescopic shaft of the second cylinder 431 is fixed to the outer ring of the third bearing 45. At this time, the up and down movement of the second traction shaft 41 can be controlled by controlling the expansion and contraction of the telescopic shaft of the second cylinder 431. When the telescopic shaft of the second cylinder 431 extends, the second traction shaft 41 moves downward, and then presses the material with the second roller shaft 42. When the telescopic shaft of the second cylinder 431 retracts, the second traction shaft 41 moves upward, creating a gap between the second traction shaft 41 and the second roller shaft 42; Arranging the second cylinders 431 at both ends of the second traction shaft 41 can keep the balance of the second traction shaft 41 during the lifting process;

[0069] In order to rotate the second roller shaft 42 through the second driving mechanism 44, the outer ring of the fourth bearing 46 is fixed to the fixed bracket 6. The second driving mechanism 44 includes a second pulley 441, a second driving wheel, a second motor and a second belt. The second driving wheel is fixed to the output shaft of the second motor, and the axis of the second driving wheel coincides with the axis of the output shaft of the second motor, so that the rotation speed of the second driving wheel is the same as that of the output shaft of the second motor. The second pulley 441 is fixed to one end face of the second roller shaft 42, and the axis of the second pulley 441 coincides with the axis of the second roller shaft 42, so that the rotation speed of the second pulley 441 is the same as that of the second roller shaft 42. When the cross-section of the second pulley 441 and the cross-section of the second driving wheel are in the same plane, and the inner ring of the second belt contacts the arc surface of the second pulley 441 and the arc surface of the second driving wheel at the same time, and the second belt is in a taut state, the rotational force generated by the output shaft of the second motor is transmitted by the second driving wheel through the second belt, and the second belt drives the second pulley 441 to rotate, thereby rotating the second roller shaft 42 fixed with the second pulley 441. Here, the transmission mode of the second pulley 441 and the second driving wheel through the second belt is the same as the transmission mode of the driving wheel and the driven wheel through the belt recorded in Chinese Patent Application No. 201720041003.9.

[0070] The two first cylinders 131 are located at the same height. When the telescopic shafts of the first cylinders 131 at the same height extend by the same length, the axis of the first traction shaft 11 can be maintained parallel to the axis of the first roller shaft 12, preventing one end of the first traction shaft 11 from tilting, thereby affecting the clamping effect between the first traction shaft 11 and the first roller shaft 12.

[0071] The two second cylinders 431 are located at the same height. When the telescopic shafts of the second cylinders 431 at the same height extend by the same length, the axis of the second traction shaft 41 can be maintained parallel to the axis of the second roller shaft 42, preventing one end of the second traction shaft 41 from tilting, thereby affecting the clamping effect between the second traction shaft 41 and the second roller shaft 42.

[0072] As Figure 3 shown, the bag making machine provided in Embodiment 1 of the present utility model preferably includes a cutting assembly 3 for cutting materials, and the cutting assembly 3 includes a tool assembly 31 for cutting the placed materials and a horizontal moving mechanism 32 for pushing the tool 31 to move.

[0073] The horizontal movement mechanism 32 includes a linear guide rail 321 and a slider 322. The track line of the linear guide rail 321 is parallel to the axis of the first roller shaft 12. The linear guide rail 321 is arranged between the first roller shaft 12 and the second roller shaft 42 and is fixed to the fixed bracket 6. The slider 322 is vertically arranged on one side of the linear guide rail 321 and can move along the track line of the linear guide rail 321. The horizontal movement mechanism 32 here is an electric slide table;

[0074] The tool assembly 31 is fixed to the slider 322. The tool assembly 31 can follow the movement of the slider 322 to cut the material on the movement track of the slider 322. The tool assembly 31 includes a tool 311 for cutting the material and a third vertical movement mechanism 312. The third vertical movement mechanism 312 can drive the tool 311 to move in the vertical direction. The cutting edge of the tool 311 faces the flat plate 5. By raising the tool 311 through the third vertical movement mechanism 312, the tool 311 cannot cut the material on the flat plate 5 at this time. By lowering the tool 311 through the vertical movement mechanism 312, the cutting edge of the tool 311 can contact the material on the flat plate 5 at this time. When the material entering from the feeding assembly 1 is sealed by the sealing assembly 2, it is cut by the cutting assembly 3. The tool 311 follows the slider 322 to move linearly on the linear guide rail 321 and cuts the material.

[0075] As Figures 3 - 4 shown, for the bag making machine provided in Embodiment 1 of the present invention, preferably, the horizontal movement mechanism 32 further includes a plurality of photoelectric sensors 323 for recording the position of the slider 322;

[0076] In order to control the moving distance and position of the slider 322 through the photoelectric sensor 323, the emitter and the receiver of the photoelectric sensor 323 are arranged facing each other. The centers of the emitter and the receiver of the photoelectric sensor 323 are connected to form a first straight line, which is the trajectory of the light signal emitted by the emitter of the photoelectric sensor 323. The first straight line is perpendicular to the trajectory straight line of the linear guide 321. A baffle 3221 is provided on the slider 322, and the plane of the baffle 3221 is perpendicular to the first straight line. When the slider 322 is arranged between the two photoelectric sensors 323 and slides to the position of the photoelectric sensor 323, the plane of the baffle 3221 on the slider 322 is perpendicular to the first straight line, that is, the baffle 3221 blocks the light signal emitted by the emitter of the photoelectric sensor 323, enabling the photoelectric sensor 323 to confirm that the slider 324 has slid to the position of this photoelectric sensor 323, and controlling the slider 322 through the controller 72 to make the slider 322 slide in the opposite direction along the linear guide 321. Therefore, by adjusting the positions of the two photoelectric sensors 323 on the linear guide 321, the reciprocating movement of the slider 322 in the set area can be realized, so as to adapt to the cutting of materials of different sizes and improve the reusability of the bag making machine.

[0077] As Figure 3 and Figure 5 shown, in the bag making machine provided by Embodiment 1 of the present utility model, preferably, in order to realize the function of driving the cutter 311 to move vertically by the third vertical moving mechanism 312, the third vertical moving mechanism 312 is a third air cylinder, which is fixed on the slider 322. The third air cylinder will slide along with the slider 322, and the telescopic shaft of the third air cylinder is fixed to the cutter 311, that is, the cutter 311 also slides along with the slider 322, and the cutter 311 extends or contracts due to the movement of the telescopic shaft of the third air cylinder. Further, the telescopic shaft of the third air cylinder is directed towards the flat plate 5, so that the distance between the cutting edge of the cutter 311 and the flat plate 5 can be adjusted. If the telescopic shaft of the third air cylinder extends, the cutting edge of the cutter 311 contacts the material on the flat plate 5. At this time, by moving the slider 322 on the linear guide 321, the cutter 311 can cut the material on the flat plate 5 along the trajectory straight line of the linear guide 321. If the telescopic shaft of the third air cylinder contracts, the cutter 311 is spaced from the flat plate 5 by a certain distance. At this time, it can be controlled that the cutter 311 does not cut the material on the flat plate 5.

[0078] As Figure 5As shown in the figure, for the bag-making machine provided in Embodiment 1 of the present utility model, preferably, the cutter 31 is a circular cutter. In order to enable the circular cutter to cut the material on the flat plate 0, the circular cutter is vertically arranged and rotatably fixed on the telescopic shaft of the third cylinder. When the cutting edge of the circular cutter abuts against the material on the flat plate 5, it slides along with the slider 322, and the circular cutter rotatably cuts the material on the flat plate 5. Using a rotatable circular cutter can reduce the wear generated when the cutter 31 contacts the flat plate 5 and improve the service life of the bag-making machine.

[0079] As Figure 2 As shown in the figure, for the bag-making machine provided in Embodiment 1 of the present utility model, preferably, in order to seal the bag mouth, the sealing assembly 2 includes a plurality of fourth cylinders 21 and heating rods 22. When the heating rod 22 approaches the material, the double-layer material can be sealed by high temperature. In order to control the bag-making machine to perform sealing processing on the material, the telescopic shaft of the fourth cylinder 21 faces the flat plate 5, and the telescopic shaft of the fourth cylinder 21 is fixed to the heating rod 22. At this time, the lifting and pressing processes of the heating rod 22 can be controlled by the fourth cylinder 21. Further, the process of the fourth cylinder 21 controlling the heating rod 22 to press down or lift towards the flat plate 5; the axis of the heating rod 22 is parallel to the track straight line of the linear guide rail, so that the heating rod 22 can seal one side of the material parallel to the axis of the first traction shaft 11; the fourth cylinder 21 is fixed on one side surface of the linear guide rail 321, and the fourth cylinder 21 and the slider 322 are located on both sides of the linear guide rail 321 respectively. All the fourth cylinders 21 are arranged at equal intervals, so that the heating rod 22 receives a uniform force for lifting and pressing. All the fourth cylinders 21 are at the same height, so that the axis of the heating rod 22 is parallel to the plane of the flat plate 5, preventing one end of the heating rod 22 from contacting the flat plate 5 first during the pressing process, thereby causing damage to the heating rod 22 and improving the service life of the bag-making machine; when the feeding assembly 1 feeds the material into the bag-making machine, it is necessary to perform sealing processing on the material first. At this time, the telescopic shaft of the fourth cylinder 21 arranged on the linear guide rail 321 extends downward, driving the heating rod 22 fixed on the telescopic shaft of the fourth cylinder 21 to move downward. The heating rod 22 contacts the material on the flat plate 5, and the double-layer material is sealed by high temperature. Then, the fourth cylinder 21 controls the telescopic shaft to contract upward, so that the heating rod 22 is away from the flat plate 5.

[0080] As Figure 2As shown in the figure, the bag making machine provided in Embodiment 1 of the present utility model. Preferably, in order to prevent excessive pressure when the fourth cylinder 21 presses down, which may cause damage to the heating rod 22, it is necessary to buffer the downward pressure of the heating rod 22. For this purpose, the sealing component further includes a plurality of spring buffers 23. The spring buffers 23 are vertically fixed between the fourth cylinder 21 and the heating rod 22. When the spring buffers 23 are vertically arranged, the springs inside the spring buffers 23 can be deformed by force, thereby buffering the pressure. All the spring buffers 23 are arranged at equal intervals, so that the pressure received by the heating rod 22 is evenly distributed to each spring buffer 23, preventing excessive pressure at a certain part of the heating rod 22. When the telescopic shaft of the fourth cylinder 21 moves downward, the heating rod 22 presses downward towards the flat plate 5. When the heating rod 22 contacts the flat plate 5, the springs on the spring buffers 23 are deformed by force, storing the pressure from the telescopic shaft of the fourth cylinder 21 and reducing the reaction force generated between the heating rod 22 and the flat plate 5. When the telescopic shaft of the fourth cylinder 21 retracts upward, the heating rod 22 moves upward accordingly. At this time, the heating rod 22 is away from the flat plate 5, and there is no reaction force between the heating rod 22 and the flat plate 5, and the springs on the spring buffers 23 return to their original state.

[0081] As Figure 6 shown in the figure, the bag making machine provided in Embodiment 1 of the present utility model preferably further includes an electric cabinet assembly 7. The electric cabinet assembly 7 includes an electric cabinet 71 and a controller 72. The controller 72 is arranged inside the electric cabinet 71. The electric cabinet 71 is located below the flat plate 5. The top of the electric cabinet 71 is provided with louvers 711 for dissipating heat from the internal controller 72. In order to prevent dust from entering the louvers 711, a filter screen is provided below the louvers 711.

[0082] As Figure 8 shown in the figure, the bag making machine provided in Embodiment 1 of the present utility model preferably has the controller 72 electrically connected to the first vertical moving mechanism 13, the first driving mechanism 14, the second vertical moving mechanism 41, the second driving mechanism 44, the horizontal moving mechanism 32, the third vertical moving mechanism 312 and the fourth cylinder 21 respectively. Through the controller 72, the movement of some structures in the bag making machine is scheduled, so that a complete processing flow can be formed.

[0083] In summary, the bag making machine provided by the present utility model can solve the problem that in the prior art, when transporting materials, due to uneven thickness of the materials, it is difficult for the feeding driving roller and the feeding driven roller to keep the materials in a clamped state, thereby affecting the transmission rate of the materials, and can realize the feeding rate of the stable bag making machine and reduce the influence of the material transportation process on the production of the bag making machine.
