Abstract
Description
Technical Field
[0001] This utility model relates to the field of molding machines, and in particular to a multi-station circulating tote bag molding machine. Background Technology
[0002] A tote bag forming machine is a mechanical device used to produce tote bags. It is widely used in the packaging industry, especially in retail, supermarkets, food, and daily chemical industries, to produce various types of shopping bags and gift bags.
[0003] When sewing the tote bag, the material placement plate is placed at the first station of the workbench. The first pressure plate in the middle of the workbench is then rotated by the controller to the top of the placement plate. The controller then activates the first electric slide rail, causing the first pressure plate to press against the material on the placement plate. The internal motor of the workbench rotates the turntable, moving the placement plate and material from the first station to the second station. A new placement plate and material are then placed at the first station. The first electric telescopic rod on the turntable pushes the placement plate to the second pressure plate. The second pressure plate on the third electric slide rail presses and secures the material on the placement plate. The second electric slide rail and the second electric telescopic rod work together to move the placement plate. The sewing machine on the workbench then sews the edges of the tote bag, completing its shape. The placement plate at the second station is then removed. This process is repeated continuously, sending the material from the first station to the second station for sewing. When the placement plate is placed in the first station, the maximum movement position of the placement plate cannot be quickly located, which affects the placement block from quickly being placed under the first pressure plate, thus causing problems that affect the performance of the tote bag forming machine. Utility Model Content
[0004] The technical problem this invention aims to solve is that when the placement plate is placed in the first station, the maximum movement position of the placement plate cannot be quickly located, which affects the placement block from quickly being placed at the lower end of the first pressure plate, thus affecting the performance of the tote bag forming machine.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-station circulating tote bag forming machine, including a worktable, a turntable on one side of the worktable, two first electric telescopic rods on the upper end of the turntable, a first electric slide rail on the output end of the two first electric telescopic rods, a first pressure plate on one side of the first electric slide rail, a second electric telescopic rod on one side of the worktable, a second electric slide rail on the output end of the second electric telescopic rod, a third electric slide rail on one side of the second electric slide rail, a second pressure plate on one side of the third electric slide rail, a sewing machine on the side of the worktable near the second pressure plate, a controller on one side of the worktable, a placement plate on the surface of the worktable, and a positioning device on the side of the worktable away from the sewing machine, the positioning device positioning the placement plate on the surface of the worktable.
[0006] The aforementioned components achieve the following effect: When sewing and forming the tote bag, the placement plate for the tote bag material is placed at the first station of the workbench. At this time, the positioning device limits the maximum displacement of the placement plate on the workbench. Then, the placement plate quickly positions itself laterally and moves longitudinally to the appropriate area of the first station. The first pressure plate in the middle of the workbench is then rotated by the controller to reach the upper part of the placement plate. Immediately afterwards, the controller activates the first electric slide rail, causing the first pressure plate to be pressed against the surface material of the placement plate. Then, the internal motor of the workbench is controlled to rotate the turntable on the workbench, thereby driving the material placed at the first station... When the placement board and tote bag material arrive at the second workstation, the first workstation places a new placement board and tote bag material. Then, the first electric telescopic rod on the turntable pushes the placement board to the second pressure plate. Next, the second pressure plate on the third electric slide rail presses and fixes the tote bag material on the placement board. The second electric slide rail and the second electric telescopic rod work together to move the placement board. Then, the sewing machine on the worktable sews the edges of the tote bag to complete the shaping of the tote bag. The placement board at the second workstation is then removed. Finally, the above operation is repeated continuously to send the tote bag material from the first workstation to the second workstation for sewing and shaping.
[0007] Preferably, the worktable is provided with an installation assembly on the side away from the sewing machine. The installation assembly fixes the positioning device to one side of the worktable. The positioning device includes an adjusting slide rail, a sliding block, a positioning block, a first bolt, a locking block, and a locking hole on one side of the adjusting slide rail. The adjusting slide rail is located on the side of the worktable away from the sewing machine. The sliding block moves inside the adjusting slide rail to drive the positioning block to move longitudinally. The positioning block moves laterally on one side of the sliding block. The first bolt is inserted into the sliding block near the positioning block to fix the positioning block. The locking block is inserted into the locking block near the adjusting slide rail and reaches the locking hole on the adjusting slide rail side to fix the sliding block.
[0008] The aforementioned components achieve the following effects: When using placement plates of different sizes, the sliding block can be moved within the slide rail, causing the positioning block to move longitudinally, moving it away from or closer to the sewing machine. Then, the positioning block is moved laterally to one side of the sliding block, reaching a suitable position to position the placement plate. Next, the first threaded bolt inside the sliding block is rotated to abut and fix the bolt against the positioning block. Then, the locking block is moved through the sliding block to a locking hole on one side of the adjusting slide rail, fixing the sliding block's position. After the positioning block is adjusted and its position fixed, it begins to limit the maximum lateral displacement of the placement plate. By using the positioning device, the maximum displacement of the placement plate on the worktable can be limited. The placement plate is then quickly positioned laterally and moves longitudinally to the appropriate area of the first workstation, thereby improving the efficiency of the cyclic feeding process and ultimately enhancing the performance of the tote bag forming machine.
[0009] Preferably, an operating block is provided on one side of the first bolt, and the operating block raises the dimension of one side of the first bolt.
[0010] The effect achieved by the above components is that by fixing the operating block to the first bolt, the dimension of one side of the first bolt is increased, making it easier for the first bolt to rotate.
[0011] Preferably, the positioning block is provided with a rubber pad on the side near the first bolt, and the rubber pad increases the friction on one side of the positioning block.
[0012] The effect achieved by the above components is as follows: by fixing the rubber pad and the positioning block to the side near the first bolt, the friction is increased when the first bolt contacts the positioning block, thereby making the first bolt better abut and fix to the positioning block.
[0013] Preferably, a connecting rope is provided on one side of the locking block, and the connecting rope connects the locking block to the adjusting slide rail.
[0014] The effect achieved by the above components is to connect the locking block to the adjusting slide rail via the connecting rope, so as to prevent the locking block from being lost and thus affecting the subsequent fixing of the adjusting block by the locking block.
[0015] Preferably, the adjusting slide rail is provided with a reinforcing rod inside, which passes through the sliding block to improve the connection strength between the sliding block and the adjusting slide rail.
[0016] The effect achieved by the above components is to improve the connection strength between the sliding block and the adjusting slide rail by adjusting the sliding of the reinforcing rod fixed inside the slide rail, thereby preventing the two from separating.
[0017] Preferably, the mounting assembly includes a square tube, a second bolt, and a mounting plate. The square tube is disposed on the side of the worktable away from the sewing machine. The second bolt is inserted into the square tube and fixed to the mounting plate. One side of the mounting plate is connected to an adjusting slide rail.
[0018] The effect achieved by the above components is as follows: When using the positioning device, the adjusting slide rail can be moved so that the mounting plate fixed on one side of the adjusting slide rail can be inserted, and the square tube fixed on the side of the worktable away from the sewing machine can be inserted. Then, the second bolt can be rotated so that the second bolt passes through the square tube and is threaded to the mounting plate, thus completing the fixing of the adjusting slide rail position. By using the mounting components, the positioning device can be quickly installed and fixed, which makes it convenient for operators to use the positioning device in the future.
[0019] Preferably, a trapezoidal block is provided on one side of the mounting plate, and the trapezoidal block reduces the size of one side of the mounting plate.
[0020] The effect achieved by the above components is to reduce the size of one side of the mounting plate by fixing the trapezoidal block on one side of the mounting plate, making it easier to insert the mounting plate into the square tube.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] By using a positioning device, the maximum displacement of the placement plate on the worktable can be limited. Then, the placement plate can be quickly positioned laterally and then moved longitudinally to reach the appropriate area of the first work station, thereby improving the efficiency of cyclic feeding and thus improving the performance of the tote bag forming machine.
[0023] By using the installation components, the positioning device can be quickly installed and fixed, making it convenient for operators to use the positioning device later. Attached Figure Description

[0032] Figures 1 to 4 The multi-station circulating tote bag forming machine shown includes a workbench 1. The workbench 1 is characterized by: a turntable 2 on one side, two first electric telescopic rods 3 on the upper end of the turntable 2, a first electric slide rail 4 at the output end of the two first electric telescopic rods 3, a first pressure plate 5 on one side of the first electric slide rail 4, a second electric telescopic rod 6 on one side of the workbench 1, a second electric slide rail 7 at the output end of the second electric telescopic rod 6, a third electric slide rail 8 on one side of the second electric slide rail 7, a second pressure plate 9 on one side of the third electric slide rail 8, a sewing machine 10 on the side of the workbench 1 near the second pressure plate 9, a controller 11 on one side of the workbench 1, a placement plate 12 on the surface of the workbench 1, and a positioning device 13 on the side of the workbench 1 away from the sewing machine 10, which positions the placement plate 12 on the surface of the workbench 1.
[0033] Figures 1 to 4As shown, during the sewing and forming of the tote bag, the placement plate 12 for placing the tote bag material is placed at the first station of the workbench 1. At this time, the positioning device 13 limits the maximum displacement of the placement plate 12 on the workbench 1. Then, the placement plate 12 quickly positions itself horizontally and moves vertically to the appropriate area of the first station. Then, the first pressure plate 5 in the middle of the workbench 1 is controlled by the controller 11 to rotate to the upper end of the placement plate 12. Immediately afterwards, the controller 11 activates the first electric slide rail 4, so that the first pressure plate 5 is pressed into contact with the surface material of the placement plate 12 by the first electric slide rail 4. Then, the controller controls the motor inside the workbench 1 to rotate the turntable 2 on the workbench 1, thereby driving the placement plate 12 at the first station. 2. When the tote bag material arrives at the second workstation, a new placement plate 12 and tote bag material are placed back into the first workstation. Then, the first electric telescopic rod 3 on the turntable 2 pushes the placement plate 12 to the second pressure plate 9. Next, the second pressure plate 9 on the third electric slide rail 8 presses and fixes the tote bag material on the placement plate 12. The second electric slide rail 7 and the second electric telescopic rod 6 work together to move the placement plate 12. Then, the sewing machine 10 on the worktable 1 sews the edges of the tote bag, completing the tote bag forming. Then, the placement plate 12 is removed from the second workstation. Finally, the above operation is repeated continuously, sending the tote bag material from the first workstation to the second workstation for sewing and forming. The first electric telescopic rod 33 and the second electric telescopic rod 6 can be model JC35FA17, the first electric slide rail 4, the second electric slide rail 7, and the third electric slide rail 8 can be model HGX28, and the motor model can be SER-060-18.
[0034] Figures 1 to 4 The workbench 1 shown is provided with an installation assembly 14 on the side away from the sewing machine 10. The installation assembly 14 fixes the positioning device 13 to one side of the workbench 1. The positioning device 13 includes an adjusting slide rail 131, a sliding block 132, a positioning block 133, a first bolt 134, a locking block 135, and a locking hole 136 opened on one side of the adjusting slide rail 131. The adjusting slide rail 131 is located on the side of the workbench 1 away from the sewing machine 10. The sliding block 132 moves inside the adjusting slide rail 131 to drive the positioning block 133 to move longitudinally. The positioning block 133 moves laterally on one side of the sliding block 132. The first bolt 134 is inserted into the sliding block 132 near the positioning block 133 to fix the positioning block 133. The locking block 135 is inserted into the side of the locking block 135 near the adjusting slide rail 131 and reaches the locking hole 136 on one side of the adjusting slide rail 131 to fix the sliding block 132.
[0035] Figures 1 to 4As shown, when using placement plates 12 of different sizes, the sliding block 132 can be moved to move within the slide rail, thereby driving the positioning block 133 to move longitudinally, moving it away from or closer to the sewing machine 10. Then, the positioning block 133 is moved laterally to one side of the sliding block 132, and then the positioning block 133 is moved to the appropriate position to position the placement plate 12. Then, the first bolt 134, which is internally threaded to the sliding block 132, is rotated to abut and fix the first bolt 134 against the positioning block 133. Immediately afterwards, the locking block 135 is moved. The locking block 135 passes through the sliding block 132 and reaches the locking hole 136 on one side of the adjusting slide rail 131 to fix the position of the sliding block 132. Then, the position of the positioning block 133 is fixed after adjustment, so that the positioning block 133 begins to limit the maximum lateral displacement of the placement plate 12. By using the positioning device 13, the maximum displacement of the placement plate 12 on the worktable 1 can be limited. Then, the placement plate 12 is quickly positioned in the lateral position and then moves longitudinally to reach the appropriate area of the first working position, thereby improving the efficiency of the cyclic feeding and thus improving the use effect of the tote bag forming machine.
[0036] Figures 1 to 4 An operating block 137 is provided on one side of the first bolt 134, which raises the dimension of one side of the first bolt 134. By fixing the operating block 137 to the first bolt 134, the dimension of one side of the first bolt 134 is raised, making it easier for the first bolt 134 to rotate. A rubber pad 138 is provided on the side of the positioning block 133 near the first bolt 134, which increases the friction on one side of the positioning block 133. By fixing the rubber pad 138 to the side of the positioning block 133 near the first bolt 134, the friction is increased when the first bolt 134 contacts the positioning block 133, thus better securing the first bolt 134 to the positioning block 133. A connecting rope 139 is provided on one side of the locking block 135, which connects the locking block 135 to the adjusting slide rail 131. Connecting the locking block 135 to the adjusting slide rail 131 with the connecting rope 139 prevents the locking block 135 from being lost, which would affect its subsequent fixation of the adjusting block. The adjusting slide rail 131 has a reinforcing rod 1310 inside, which passes through the sliding block 132 to improve the connection strength between the sliding block 132 and the adjusting slide rail 131. By adjusting the sliding block 132 through the reinforcing rod 1310 fixed inside the adjusting slide rail 131, the connection strength between the sliding block 132 and the adjusting slide rail 131 is improved, preventing them from separating.
[0037] Figures 1 to 4The mounting assembly 14 shown includes a square tube 141, a second bolt 142, and a mounting plate 143. The square tube 141 is located on the side of the worktable 1 away from the sewing machine 10. The second bolt 142 is inserted into the square tube 141 and fixed to the mounting plate 143. One side of the mounting plate 143 is connected to the adjusting slide rail 131. When using the positioning device 13, the adjusting slide rail 131 can be moved so that the mounting plate 143 fixed on one side of the adjusting slide rail 131 is inserted into the square tube 141 fixed on the side of the worktable 1 away from the sewing machine 10. Then, the second bolt 142 is rotated so that the second bolt 142 passes through the square tube 141 and is threadedly fixed to the mounting plate 143, thus completing the fixation of the position of the adjusting slide rail 131. By using the mounting assembly 14, the positioning device 13 can be quickly installed and fixed, making it convenient for operators to use the positioning device 13 subsequently.
[0038] Figures 1 to 4 The mounting plate 143 shown has a trapezoidal block 144 on one side, which reduces the size of one side of the mounting plate 143. By fixing the trapezoidal block 144 to one side of the mounting plate 143, the size of one side of the mounting plate 143 is reduced, making it easier to insert the mounting plate 143 into the square tube 141.
[0039] Working principle: When sewing and forming the tote bag, the placement plate 12 for placing the tote bag material is placed at the first station of the workbench 1. At this time, the positioning device 13 limits the maximum displacement of the placement plate 12 on the workbench 1. Then, the placement plate 12 quickly positions itself horizontally and moves vertically to the appropriate area of the first station. Then, the first pressure plate 5 in the middle of the workbench 1 is controlled by the controller 11 to rotate to the upper end of the placement plate 12. Immediately afterwards, the controller 11 activates the first electric slide rail 4, so that the first pressure plate 5 is pressed into contact with the surface material of the placement plate 12 by the first electric slide rail 4. Then, the controller controls the motor inside the workbench 1 to rotate the turntable 2 on the workbench 1, thereby driving the placement plate at the first station. When the material for the tote bag arrives at the second workstation, the first workstation places a new placement plate 12 and the material for the tote bag back in. Then, the first electric telescopic rod 3 on the turntable 2 pushes the placement plate 12 to the second pressure plate 9. Next, the second pressure plate 9 on the third electric slide rail 8 presses and fixes the material for the tote bag on the placement plate 12. The second electric slide rail 7 and the second electric telescopic rod 6 work together to move the placement plate 12. Then, the sewing machine 10 on the worktable 1 sews the edges of the tote bag to complete the shaping of the tote bag. Then, the placement plate 12 on the second workstation is removed. Finally, the above operation is repeated continuously to send the material for the tote bag on the first workstation to the second workstation for sewing and shaping. When using placement plates 12 of different sizes, the sliding block 132 can be moved to move within the slide rail, thereby driving the positioning block 133 to move longitudinally, moving the positioning block 133 away from or closer to the sewing machine 10. Then, the positioning block 133 is moved laterally to move to one side of the sliding block 132, and then the positioning block 133 is moved to the appropriate position to position the placement plate 12. Then, the first bolt 134, which is internally threaded to the sliding block 132, is rotated to abut and fix the first bolt 134 against the positioning block 133. Immediately afterwards, the locking block 135 is moved to lock... Block 135 passes through sliding block 132 and reaches the inside of the locking hole 136 on one side of adjusting slide rail 131 to fix the position of sliding block 132. Then, the position of positioning block 133 is fixed after adjustment, so that positioning block 133 begins to limit the maximum lateral displacement of placement plate 12. By using positioning device 13, the maximum displacement of placement plate 12 on worktable 1 can be limited. Then, placement plate 12 quickly positions itself in the lateral position and then moves longitudinally to reach the appropriate area of the first work station, thereby improving the efficiency of cyclic feeding and thus improving the use effect of the tote bag forming machine.
[0040] When using the positioning device 13, the adjusting slide rail 131 can be moved so that the mounting plate 143 fixed on one side of the adjusting slide rail 131 can be inserted, and the square tube 141 fixed on the side of the worktable 1 away from the sewing machine 10 can be inserted. Then, the second bolt 142 can be rotated so that the second bolt 142 passes through the square tube 141 and is threadedly fixed to the mounting plate 143. Then the position of the adjusting slide rail 131 can be fixed. By using the mounting assembly 14, the positioning device 13 can be quickly installed and fixed, which makes it convenient for operators to use the positioning device 13 in the future.
