Description

Technical Field

[0001] This invention relates to the field of woven bag cutting technology, and in particular to a woven bag cutting device. Background Technology

[0002] Woven bags are a type of plastic bag used for packaging.

[0003] Currently, woven bags are typically cut using hot wire cutting. Hot cutting can prevent the production of debris at the cutting point. However, when using hot wire cutting, impurities tend to adhere to the surface of the hot wire. After the cutting process is completed or when the hot wire needs to be stopped and allowed to cool down, workers need to clean the impurities adhering to the surface of the hot wire to avoid excessive impurities affecting the cutting operation.

[0004] However, after the heating element is deactivated, it quickly returns to its initial state from its red-hot state. In this state, the heating element still retains residual heat and should not be touched directly. Since there is currently no shielding structure, the color of the heating element after deactivation is the same as that of the unheated heating element. If other workers are unaware that the heating element has just been deactivated or has been deactivated for a short period of time, they may cause burns if they directly touch the heating element to process impurities, posing a safety hazard. Summary of the Invention

[0005] In view of this, the present invention provides a woven bag cutting device, which achieves limiting fixation through the limiting insertion of a limiting block and a through-hole. This prevents the rectangular shielding frame A and rectangular shielding frame B from being disassembled before the limiting fixation of the limiting block is released. Therefore, when it is necessary to clean the impurities attached to the surface of the heating wire, the limiting fixation of the limiting block must be released first. During the process of releasing the limiting fixation of the limiting block, the plastic insert can be forced into contact with the heating wire. This allows the operator to observe whether the plastic insert is deformed through the transparent shielding glass B, thus facilitating the operator's judgment on whether the heating wire has been completely cooled and whether there is residual heat.

[0014] Beneficial effects

[0015] 1. In this invention, the heating wire is normally shielded by a rectangular shielding frame A, a transparent shielding glass A, a rectangular shielding frame B, a transparent shielding glass B, and a sealing plate. This avoids direct contact by workers without affecting the cutting operation, thus preventing the risk of burns caused by workers directly contacting the heating wire without knowing whether it has cooled down completely.

[0016] 2. The present invention uses a limiting engagement block that is fixedly connected to rectangular shielding frame A and rectangular shielding frame B. In normal operation, the limiting engagement block achieves limiting fixation through the limiting insertion hole. This prevents the rectangular shielding frame A and rectangular shielding frame B from being disassembled before the limiting engagement block is released. Therefore, when cleaning impurities attached to the surface of the heating wire, the limiting engagement block must be released first. During the process of releasing the limiting engagement block, the plastic insert can be forced into contact with the heating wire. This allows the operator to observe whether the plastic insert is deformed through the transparent shielding glass B, thus facilitating the operator's judgment on whether the heating wire has been completely cooled and whether there is residual heat.

The auxiliary roller 109 is located on the right side of the adjacent conveyor belt 1, and the auxiliary roller 109 does not contact the conveyor belt 1. The outer circumferential surface of the auxiliary roller 109 is at the same horizontal plane as the top surface of the outer circumference of the conveyor belt 1. A conveying inclined plate 105 is fixedly installed on the right side between the two side baffles 101. The conveying inclined plate 105 is inclined on the left and lower on the right. The left end of the conveying inclined plate 105 is located on the right side of the adjacent auxiliary roller 109. A top seat 106 is provided above the right side of the two side baffles 101. The top seat 106 has a rectangular block structure. The bottom end of the top seat 106 is fixedly connected to the top end of the two side baffles 101 by two support blocks 1015 that are symmetrically distributed on the left and right. A device electrically connected to the control box 104 is fixedly installed on the top end of the top seat 106. The electric cylinder 107 is connected; a pressure plate 1010 is provided below the top seat 106. The bottom surface of the pressure plate 1010 is symmetrically arranged with two side protrusions 1012. An electric heating wire 1017 is installed between the two side protrusions 1012. The electric heating wire 1017 is electrically connected to the control box 104. The position of the electric heating wire 1017 corresponds to the gap between the conveyor belt 1 and the conveyor auxiliary roller 109. The top surface of the top seat 106 is symmetrically arranged with two limiting holes 1016. The top surface of the pressure plate 1010 is provided with two limiting posts 1011. The limiting posts 1011 are slidably inserted into the limiting holes 1016. Through the cooperation of the limiting posts 1011 and the limiting holes 1016, the pressure plate 1010 can be adjusted when it moves up and down. It is limited to ensure that its up and down movement will not deviate at an angle. A matching notch 1013 is opened on the right side of the top surface of each of the two side baffles 101. The matching notch 1013 is a rectangular groove structure. The matching notch 1013 corresponds to the gap between the conveyor belt 1 and the conveyor auxiliary roller 109. The rear end face of the pressure plate 1010 is on the same vertical plane as the rear end face of the side baffle 101. A sealing plate 108 is fixedly installed on the rear end face of the side baffle 101. The sealing plate 108 blocks the matching notch 1013 located at the rear. By sealing the matching notch 1013 located at the rear with the sealing plate 108, it can prevent the staff from contacting the heating wire 1017 through the matching notch 1013 located at the rear.The front end of the pressure plate 1010 and the side protrusion 1012 located on the front side are positioned in front of the side baffle 101.

[0039] Among them, a limiting mating block 2 is provided in front of the side baffle 101 on the front side. The limiting mating block 2 has a rectangular block structure. A rectangular shielding frame plate A201 is provided on both the left and right sides of the top surface of the limiting mating block 2. The bottom surface of the rectangular shielding frame plate A201 is fixedly connected to the top surface of the limiting mating block 2 by a connecting block 205.

A mating baffle 20 is fixedly installed on the rear surface of the two rectangular shielding frame plates A201. 6. The baffle 206 is a rectangular plate structure, and the bottom of the baffle 206 is lower than the bottom surface of the rectangular shielding frame A201. The front surfaces of the two rectangular shielding frames A201 are fixedly installed with a rectangular shielding frame B203. A transparent shielding glass B204 is fixedly installed in the inner area of ​​the rectangular shielding frame B203. Through the transparent shielding glass A202 and the transparent shielding glass B204, it is convenient for the staff to observe the heating wire 1017 while avoiding the staff from touching the heating wire 1017.

[0040] The limiting mating block 2 has a rotating through groove 2012 on its rear side. The rotating through groove 2012 is a circular groove structure and passes through the top and bottom surfaces of the limiting mating block 2. The rotating through groove 2012 corresponds to the position of the heating wire 1017 located in front of the side baffle 101. A through limiting insertion hole 2014 is provided on the left side of the rear side of the inner end of the rotating through groove 2012. A receiving groove 1018 is provided on the front surface of the side baffle 101 located on the front side. The receiving groove 1018 is a circular groove structure. A limiting block 1019 is inserted into the slot 1018. The limiting block 1019 has a cylindrical structure. The rear end face of the limiting block 1019 is fixedly connected to the rear side of the inner end of the receiving groove 1018 by a return spring A1020. In the normal extended state of the return spring A1020, the front half of the limiting block 1019 is located outside the receiving groove 1018. When the bottom end faces of the two rectangular blocking frame plates A201 are in contact with the top end faces of the side baffle 101, the front end faces of the two mating baffle plates 206 are in contact with the rear end faces of the side baffle 101 located on the rear side, and the two rectangular blocking frame plates A201 are in contact with the rear end faces of the side baffle 101 located on the rear side, the limiting block 1019 is in contact with the rear side face of the side baffle 101 located on the rear side. When 01 is located on the left and right sides of the top seat 106, the through-limiting insertion hole 2014 and the receiving groove 1018 are coaxial. The front half of the limiting insertion block 1019 is inserted into the through-limiting insertion hole 2014. A reciprocating sliding groove 2021 is opened on the inner circumferential surface of the through-limiting insertion hole 2014. The reciprocating sliding groove 2021 has an annular groove structure. A pressing column 2017 is slidably installed in the through-limiting insertion hole 2014. The pressing column 2017 is cylindrical. The front end of the pressing column 2017 adopts a hemispherical structure. An annular stop block 2 is fixedly installed on the outer circumferential surface of the pressing column 2017. 019, the annular stop 2019 is slidably connected in the reciprocating slide groove 2021. The rear side of the inner end of the reciprocating slide groove 2021 is fixedly connected to the rear end face of the annular stop 2019 by a return spring B2018. When the return spring B2018 is extended, the front end of the pressing column 2017 is located outside the through-limiting insertion hole 2014. At this time, the rear end face of the pressing column 2017 is in contact with the front end face of the limiting insertion block 1019 that is inserted into the through-limiting insertion hole 2014. Therefore, when the pressing column 2017 is pressed, the pressing column 2017 will simultaneously press the limiting insertion block 1019.

[0041] The rotating through groove 2012 has a rotating through hole 2015 at the axial center of its inner front side, which is a through-limiting fitting block 2. A rotating fitting block 209 is installed inside the rotating through groove 2012. The rotating fitting block 209 has a circular block structure, and its diameter is smaller than the diameter of the rotating through groove 2012. The thickness of the rotating fitting block 209 is the same as the width of the rotating through groove 2012. A rotating column 207 is installed at the axial center of the front side of the rotating fitting block 209. The structural dimensions of the rotating column 207 are the same as the structural dimensions of the rotating through hole 2015, and the rotating column 207 is rotatably connected inside the rotating through hole 2015. A slot 208 is installed at the axial center of the front side of the rotating column 207. The slot 208 has a hexagonal slot structure. An extension block 2010 is fixedly installed below the outer peripheral surface of the rotating mating block 209. The extension block 2010 has a rectangular block structure, and the rear end face of the extension block 2010 is on the same vertical plane as the rear end face of the rotating mating block 209. The bottom end face of the extension block 2010 has three evenly distributed embedded slots 2016, and plastic inserts 2011 are inserted into the embedded slots 2016. When the rotating mating block 209 rotates counterclockwise by 90 degrees, the plastic insert 2011 comes into contact with the heating wire 1017 located in front of the side baffle 101. Through the contact between the plastic insert 2011 and the heating wire 1017, the operator can observe whether the plastic insert 2011 is deformed, thereby judging whether there is residual heat in the heating wire 1017.

[0042] A blocking block 2020 is provided on the rear side of the inner end of the rotating through groove 2012, adjacent to the lower part of the through limiting insertion hole 2014. The blocking block 2020 has a rectangular block structure. When the rotating mating block 209 rotates counterclockwise until it contacts the blocking block 2020, the front end of the rotating column 207 is pressed into the through limiting insertion hole 2014, and the limiting insertion block 1019 disengages from the through limiting insertion hole 2014 and is pressed into the receiving groove 1018. The blocking block 2020 is located on the right side. An inclined cut surface 2013 is provided between the end face and the rear face. By setting the inclined cut surface 2013, before the extension block 2010 contacts the blocking block 2020, the inclined cut surface 2013 of the extension block 2010 will first contact the front end of the pressing column 2017. The inclined cut surface 2013 will squeeze the front end of the pressing column 2017, which has a hemispherical structure, so that the pressing column 2017 is pressed into the through-limiting insertion hole 2014, so as to realize the subsequent limit release operation of the limiting mating block 2.

[0043] The specific usage and function of this embodiment are as follows:

[0044] Uncut woven bags are placed on conveyor belt 1. Motor 102 starts and controls conveyor roller 1014 to rotate, thereby driving conveyor belt 1 to rotate to the right and convey the uncut woven bags.

[0045] In coordination with the conveying speed of the conveyor belt 1, when the section of the woven bag to be cut is conveyed to the gap between the conveyor belt 1 and the conveying auxiliary roller 109, the electric cylinder 107 drives the pressure plate 1010 to move down, so that the heating wire 1017, which is in a heated state, comes into contact with the woven bag. The woven bag is cut through the heating wire 1017, thereby realizing the cutting operation of the woven bag. The cut woven bag will slide down along the conveying inclined plate 105 to realize the automatic conveying of the cut woven bag for easy collection.

[0046] When this invention is applied, the rectangular shielding frame A201, the transparent shielding glass A202, the rectangular shielding frame B203, the transparent shielding glass B204, and the sealing plate 108 together shield the heating wire 1017, so that before the rectangular shielding frame A201 and the rectangular shielding frame B203 are removed, the staff cannot directly contact the heating wire 1017 located between the two side baffles 101;

[0047] When it is necessary to disassemble rectangular shielding frame A201 and rectangular shielding frame B203, the limiting mating block 2, which is in the limiting state, needs to be released. To release it, the operator uses an Allen wrench that engages with slot 208 to rotate the rotating column 207 counterclockwise along the rotating through hole 2015. This causes the rotating mating block 209 to drive the extension block 2010 and plastic insert 2011 to rotate counterclockwise. When the counterclockwise rotation reaches ninety degrees, the plastic insert 2011 and the heating wire 1 located in front of the side baffle 101 on the front side... When the heating wire 1017 comes into contact with the barrier block 2020, the operator can observe the state of the plastic insert 2011 through the transparent shielding glass B204. If it is deformed, it means that the heating wire 1017 still has residual heat and cannot be directly contacted. It is necessary to wait for it to cool down before cleaning the surface impurities. If it is not deformed, the operator continues to rotate the rotating column 207 counterclockwise until the extension block 2010 comes into contact with the barrier block 2020. Before the extension block 2010 comes into contact with the barrier block 2020, the inclined cut surface 2013 of the extension block 2010 will first... When the extension block 2010 contacts the front end of the pressing post 2017, the inclined cut surface 2013 will compress the hemispherical front end of the pressing post 2017, thereby pressing the pressing post 2017 into the through-limiting insertion hole 2014. At the same time, the pressing post 2017 will also press against the front end of the limiting block 1019 inserted into the through-limiting insertion hole 2014. When the extension block 2010 contacts the blocking block 2020, the front end of the pressing post 2017 is completely pressed into the through-limiting insertion hole 2014, and the front end of the limiting block 1019 is pressed out of the through-limiting hole. The insertion hole 2014 is completely pressed into the receiving groove 1018. At this time, with the limiting insertion block 1019 and the through-limiting insertion hole 2014 in a limiting engagement, the limiting engagement block 2 is released. At this time, the operator can move the limiting engagement block 2 upward, thereby disassembling the rectangular shielding frame A201 and the rectangular shielding frame B203, thus exposing the part of the heating wire 1017 that it shields. At this time, the operator can directly contact the heating wire 1017 to clean the impurities attached to the surface of the heating wire 1017.
