Description

Technical Field

[0001] This utility model relates to the technical field of bag opening machines, and in particular to a tray device for a bag opening machine. Background Technology

[0002] A pocket opening machine is a mechanical device used for processing pockets in clothing. Current pocket opening machines include a laser cutting mechanism, a material fixing mechanism, a moving mechanism, a folding mechanism, and a machine head. When processing a pocket, the outer fabric is placed on the material fixing mechanism. The moving mechanism drives the material fixing mechanism to the laser cutting mechanism, where the pocket opening is cut out on the outer fabric. Then, it moves to the folding mechanism to fold the fabric at the pocket opening inwards. Finally, the pocket fabric is moved under the outer fabric and then to the machine head to sew the pocket fabric and outer fabric together.

[0003] Chinese utility model patent CN214060872U discloses a lower support plate reset device for a bag opening machine, including a worktable of the bag opening machine and a clamping mechanism for clamping or releasing the lower support plate. Initially, the lower support plate is placed at the bag folding station with the bag lip (outer fabric) in place. When processing the bag, the material fixing mechanism carries the garment (outer fabric) with the bag opening already opened to the upper part of the bag lip and clamps and fixes the lower support plate. Then, the lower support plate is moved to the sewing station to sew the garment and the bag lip. After sewing is completed, the clamping mechanism clamps the completed lower support plate and moves it backward, causing the lower support plate to exit from the sewing station. Then, it moves laterally to move it towards the bag folding station to reach the positioning state. When the lower support plate in the bag folding station moves towards the sewing station, the clamping mechanism in the positioning state moves forward to send the lower support plate into the bag folding station, ensuring the processing of the next workpiece.

[0004] When processing genuine bags, two layers of bag fabric need to be sewn under the outer fabric to form a pocket for holding items. In the aforementioned patent, the material-fixing mechanism first moves to the lower support plate carrying the first layer of bag fabric, clamps the lower support plate, and moves it to the sewing station for the first sewing. After the lower support plate is removed, the material-fixing mechanism carries the outer fabric and the first layer of bag fabric to the lower support plate carrying the second layer of bag fabric, and then clamps the lower support plate and moves it to the sewing station for the second sewing. When the material-fixing mechanism carries the outer fabric and the first layer of bag fabric, only the rear end of the first layer of bag fabric is sewn and fixed to the bag fabric. The front end of the first layer of bag fabric is prone to bending and folding during the movement. When the first layer of bag fabric moves onto the second layer of bag fabric, the folded part is prone to overlap the part of the second layer of bag fabric to be sewn, which leads to the pocket not being formed after the second layer of bag fabric is sewn, resulting in a waste of materials and labor. Utility Model Content

[0005] The purpose of this invention is to provide a tray device for a bag opening machine, which is suitable for sewing double-layered bag pockets, reducing the probability of bending and folding when the bag fabric moves, and improving the product processing quality of the bag opening machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: This utility model provides a tray device for a bag opening machine, the tray device comprising: The workbench has a bag fabric feeding station and a sewing station; A material fixing mechanism is used to fix and place the outer fabric. The material fixing mechanism is set on the worktable. The material fixing mechanism can move vertically and horizontally on the worktable to move to the bag fabric loading station or the sewing station. A rear support plate is placed at the bag fabric feeding station and is used to hold the rear end of the bag fabric. A front support plate is placed at the bag fabric feeding station and located in front of the rear support plate. The front support plate is used to place the front end of the bag fabric. The material feeding mechanism is connected to a first gripping component and a second gripping component. The first gripping component can grip or release the rear support plate, and the second gripping component can grip or release the front support plate.

[0007] In this solution, the outer fabric is fixedly placed on the material-fixing mechanism, and the bag fabric can be placed on the rear and front support plates of the bag fabric loading station. The material-fixing mechanism can move to the bag fabric loading station and grasp the front and rear support plates through the first and second gripping components, thereby vertically clamping the bag fabric between the material-fixing mechanism and the rear and front support plates, so as to carry the bag fabric and the outer fabric together to the sewing station for sewing. Specifically, the rear end of the bag fabric is placed on the rear support plate, and the front end is placed on the front support plate. Compared to the traditional solution with only one lower support plate, this solution avoids the front end of the bag fabric dragging on the worktable during movement, reducing wear on the front end of the bag fabric. Simultaneously, the operator places the second layer of bag fabric on another rear support plate at the bag fabric loading station. After the first layer of bag fabric is sewn at the sewing station, the first gripping component releases the rear support plate below the material-fixing mechanism, removing the rear support plate from the sewing station. As the material positioning mechanism moves to the bag fabric loading station to retrieve the second layer of bag fabric, the second gripping component holds the front support plate in place, preventing the front end of the first layer of bag fabric from bending or folding into the area to be sewn on the second layer. After the material positioning mechanism reaches the bag fabric loading station, the second gripping component releases the front support plate, and the first gripping component grips the rear support plate containing the second layer of bag fabric, carrying the second layer to the sewing station for sewing. At this point, the operator can place the next first layer of bag fabric on the rear support plate and the new front support plate, preparing for the next bag processing.

[0008] Therefore, the pallet device in this solution can reduce wear and tear when the first layer of bag fabric moves during bag processing, and when processing genuine bags with two layers of bag fabric, the first layer of bag fabric is less likely to bend and fold into the part of the second layer of bag fabric to be sewn, thus improving the processing quality of the bag opening machine and reducing the waste of raw materials and labor.

[0009] Furthermore, the first gripping component includes a first pneumatic gripper connected to the material fixing mechanism, and the rear support plate is provided with a first protrusion for gripping by the first pneumatic gripper.

[0010] In this solution, the material fixing mechanism uses the first pneumatic gripper to grip the first protrusion on the rear pallet, thereby achieving the gripping of the rear pallet. This method facilitates the control of the air path and thus controls the gripping or releasing of the rear pallet, and its technology is mature and has low manufacturing cost.

[0011] Furthermore, the second gripping component includes a second pneumatic gripper connected to the material fixing mechanism, and the front support plate is provided with a second protrusion for gripping by the second pneumatic gripper.

[0012] In this solution, the material fixing mechanism uses the second pneumatic gripper to grip the second protrusion on the rear pallet, thereby gripping the front pallet. This method facilitates control of the air path and thus controls the gripping or releasing of the front pallet. It is a mature technology with low cost.

[0013] Furthermore, the pallet device also includes a locking mechanism, which is disposed at the bag fabric feeding station; the locking mechanism can lock the front pallet fixed at the bag fabric feeding station, or release the front pallet from the bag fabric feeding station.

[0014] In this solution, the locking mechanism can lock and fix the front support plate on the bag fabric feeding station, so that when the fixing mechanism does not grab the front support plate, the front support plate can be stably set at the bag fabric feeding station, which makes it convenient for users to place the bag fabric on the front support plate, and at the same time makes it easy for the fixing mechanism to position and grab the front support plate.

[0015] Furthermore, the locking mechanism includes a locking cylinder and a locking pressure plate. The cylinder body of the locking cylinder is fixedly mounted on the worktable, and the piston rod of the locking cylinder is connected to the locking pressure plate. At least a portion of the locking pressure plate extends above the front support plate. The locking cylinder can drive the locking pressure plate to move downwards and press against the front support plate, or drive the locking pressure plate to move upwards and disengage from the front support plate.

[0016] In this design, the cylinder body of the locking cylinder is fixed to the worktable. The piston of the locking cylinder can drive the locking pressure plate downwards, causing the locking pressure plate to press against the front support plate, thus locking and fixing the front support plate. When the piston of the locking cylinder moves in the reverse direction, it can drive the locking pressure plate upwards to disengage from the front support plate, thereby releasing the locking of the front support plate. This locking mechanism design facilitates control of the clamping mechanism to lock and fix the front support plate or disengage it.

[0017] Furthermore, a rotating support is provided between the piston rod of the locking cylinder and the front support plate. The upper end of the rotating support is rotatably connected to the locking pressure plate along the vertical plane, and the lower end of the rotating support is rotatably connected to the worktable along the vertical plane. The piston rod of the locking cylinder is rotatably connected to the locking pressure plate along the vertical plane.

[0018] In this design, the locking plate is rotatably connected to the rotating support and the piston shaft of the locking cylinder. The rotating support is located between the piston rod of the locking cylinder and the front support plate and is rotatably connected to the worktable. This allows the locking plate to rotate around the rotating support when the piston rod of the locking cylinder pulls it down. As a result, the portion of the locking plate away from the piston rod of the locking cylinder rotates upward and tilts to disengage from the front support plate, thus releasing the locking of the front support plate. Conversely, when the piston rod of the locking cylinder pushes the locking plate upward, the locking plate rotates around the rotating support. As a result, the portion of the locking plate away from the piston rod of the locking cylinder rotates downward and presses against the front support plate, thus locking and fixing the front support plate. Therefore, the locking plate moves closer to or further away from the front support plate by rotating. When the locking plate rotates away from the front support plate, the vertical projection area of ​​the locking plate on the front support plate gradually decreases until the vertical projection of the locking plate does not overlap with the front support plate. This ensures that the locking plate will not interfere with the vertical movement of the front support plate from above, which is beneficial for the material fixing mechanism to move vertically after grabbing the front support plate.

[0019] Furthermore, a locking block protrudes upward from one end of the front support plate near the locking mechanism, and a limiting protrusion protrudes downward from the locking pressure plate; when the locking pressure plate presses against the front support plate, the limiting protrusion blocks the locking block from the side away from the locking cylinder.

[0020] In this design, when the locking plate is pressed onto the front support plate, the limiting protrusion blocks the locking block on the side away from the locking cylinder, thereby limiting the front support plate and preventing it from moving away from the locking cylinder, making the front support plate more securely locked.

[0021] Furthermore, an outer protective cover is fixedly installed on the workbench, and the outer protective cover surrounds the locking pressure plate.

[0022] In this design, the outer protective cover surrounds the locking pressure plate to prevent the user's hand from entering the working range of the locking pressure plate and being pinched by it; at the same time, the outer protective cover can also serve as a positioning structure for the front support plate, blocking the front support plate at the end facing the locking cylinder to prevent it from moving closer to the locking cylinder.

[0023] Furthermore, a positioning block is provided on the worktable, and the positioning block abuts against the end of the front support plate facing the locking mechanism.

[0024] In this solution, by setting a positioning block, the end of the front pallet can be quickly positioned by abutting against the block, so that the front pallet can be accurately placed and the second clamping component on the material positioning mechanism can grasp the front pallet.

[0025] Furthermore, a magnet is fixedly provided on the lower side of the material feeding mechanism, and the front support plate has a magnetic attraction part for the magnet to attract the material.

[0026] In this solution, the material positioning mechanism uses a magnet to attract the magnetic part on the front support plate, making the material positioning mechanism more stable when it grabs the front support plate and moves it.

[0027] In summary, this utility model has the following beneficial effects: In the pallet device of the bag opening machine of this utility model, the rear end of the bag fabric is placed on the rear pallet and the front end of the bag fabric is placed on the front pallet. This can prevent the front end of the bag fabric from dragging on the worktable when the bag fabric moves, reducing wear on the front end of the bag fabric. After the first layer of bag fabric is sewn at the sewing station, when the material setting mechanism moves to the bag fabric loading station to pick up the second layer of bag fabric, the second gripping component can hold the front pallet, preventing the front end of the first layer of bag fabric from bending and folding onto the part of the second layer of bag fabric to be sewn. This can reduce the defect rate of processing, improve the processing quality of the bag opening machine, and reduce the waste of raw materials and labor. Attached Figure Description

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] This embodiment discloses a tray device for a bag opening machine, referring to... Figure 1 The pallet device includes a worktable 100. The worktable 100 is mounted on the frame of the bag opening machine and has a cutting station, a bag folding station, a bag fabric feeding station 110, and a sewing station 120. The laser cutting device of the bag opening machine is located at the cutting station, the bag folding device is located at the bag folding station, and the sewing machine head is located at the sewing station 120.

[0039] The workbench 100 is equipped with a material fixing mechanism 200, which can move vertically and horizontally on the workbench 100 to move between the cutting station, the bag folding station, the sewing station 120 and the bag fabric feeding station 110.

[0040] The steps for processing double-layer genuine bags using a bag-opening machine are as follows: S1. Fix the fabric onto the material fixing mechanism 200.

[0041] S2. The material setting mechanism 200 moves to the cutting station, and the laser cutting device cuts the bag opening on the fabric.

[0042] S3. The material setting mechanism 200 moves to the bag folding station, and the bag folding device folds the fabric around the cut bag opening to expose the bag opening.

[0043] S4. The material fixing mechanism 200 moves to the bag fabric feeding station 110 and grabs the first layer of bag fabric below.

[0044] S5, the material setting mechanism 200 moves to the sewing station 120, and the sewing machine head sews the first layer of bag fabric under the outer fabric.

[0045] S6. The material fixing mechanism 200 moves to the bag fabric feeding station 110 and grabs the second layer of bag fabric below.

[0046] S7. The material setting mechanism 200 moves to the sewing station 120, and the sewing machine head sews the second layer of bag fabric under the outer fabric and the first layer of bag fabric.

[0047] In this embodiment, only the scheme for the material setting mechanism 200 to pick up and place bag fabric and sew between the bag fabric feeding station 110 and the sewing station 120 is improved. The laser cutting device, bag folding device and sewing machine head of the bag opening machine are existing technologies and will not be described in detail.

[0048] In addition, in other embodiments, the cutting and folding of the outer fabric can be completed on other equipment, so that the workbench 100 can only have a bag fabric feeding station 110 and a sewing station 120, which are only used to complete the sewing of the outer fabric and two layers of bag fabric.

[0049] Reference Figure 2 and Figure 3 The material setting mechanism 200 includes a lower pressure frame 210, an upper pressure frame 220, and a connecting seat 230. The lower pressure frame 210 is connected below the connecting seat 230, and the upper pressure frame 220 is positioned above the lower pressure frame 210 and connected to the connecting seat 230 via a vertically arranged cylinder. The lower pressure frame 210 has an elongated processing window 211, and the upper pressure frame 220 has an opening directly opposite the processing window 211, with the opening area of ​​the upper pressure frame 220 being larger than that of the lower pressure frame 210. The cylinder drives the upper pressure frame 220 to move towards the lower pressure frame 210 to fix the fabric onto the lower pressure frame 210, while simultaneously exposing the processing window 211 for the sewing machine head to perform sewing operations.

[0050] In this embodiment, a horizontal beam (not shown in the figure) is horizontally arranged on the workbench 100. A movable seat 300 and a transverse drive mechanism are arranged on the beam. A connecting seat 230 is connected to the movable seat 300. The transverse drive mechanism can drive the movable seat 300 to move in the longitudinal direction, thereby driving the material stationary mechanism 200 to move horizontally. The transverse drive mechanism can be a cylinder, a motor screw mechanism, a gear rack mechanism, or other suitable linear drive mechanism.

[0051] The movable seat 300 is provided with a vertical slide rail 310, and the connecting seat 230 has a slider 231 on the side facing the movable seat 300 that slides and engages with the slide rail 310. A vertically arranged lifting cylinder 320 connects the movable seat 300 and the connecting seat 230. The cylinder body of the lifting cylinder 320 is fixed to the movable seat 300, and the piston rod of the lifting cylinder 320 is connected to the connecting seat 230. Thus, the lifting cylinder 320 can drive the connecting seat 230 to move up and down, thereby driving the material fixing mechanism 200 to move vertically. In addition, in other embodiments, a motor screw mechanism, a gear rack mechanism, or other suitable linear drive mechanism can also be provided on the connecting seat 230 to drive the connecting seat 230 to move vertically.

[0052] Reference Figure 1 The bag fabric loading station 110 is equipped with a rear support plate 500 and a front support plate 400. The rear support plate 500 is used to place the rear end of the bag fabric, and the front support plate 400 is placed in front of the rear support plate 500 and is used to place the front end of the bag fabric. In this embodiment, "front side" refers to the side facing the operator, and "rear side" refers to the side away from the operator.

[0053] Reference Figure 1 and Figure 4 The rear support plate 500 is a thin plate-shaped component. A long strip-shaped clearance window 510 is provided on the rear support plate 500. The clearance window 510 can be aligned with the processing window 211 of the lower pressure frame 210 to avoid the needle when sewing the bag fabric.

[0054] The workbench 100 has multiple suction holes 111 at the bag fabric loading station 110, which are arranged in a rectangular array. The rear support plate 500 has multiple air passages 520 aligned with the suction holes 111. The suction holes 111 are connected to a negative pressure suction device. When the negative pressure suction device is working, a negative pressure is generated in the suction holes 111 and the air passages 520 to adsorb the bag fabric onto the rear support plate 500, facilitating the next processing of the bag fabric.

[0055] The front support plate 400 is a thin plate-shaped component. The front support plate 400 can be made of plastic, metal or other suitable rigid materials. In this embodiment, the front support plate 400 is specifically made of metal.

[0056] Reference Figure 2 and Figure 3 The material setting mechanism 200 is connected to a first gripping component 600 and a second gripping component 700. The first gripping component 600 can grip or release the rear pallet 500, and the second gripping component 700 can grip or release the front pallet 400.

[0057] When processing the pocket, the first layer of bag fabric is placed on the rear support plate 500 and the front support plate 400. The material fixing mechanism 200 moves to the bag fabric loading station 110 and grabs the rear support plate 500 through the first gripping component 600 and the second gripping component 700, thereby vertically clamping the bag fabric between the material fixing mechanism 200, the rear support plate 500, and the front support plate 400, so as to carry the bag fabric and the outer fabric together to the sewing station 120 for sewing. In this embodiment, the rear end of the bag fabric is placed on the rear support plate 500 and the front end of the bag fabric is placed on the front support plate 400. Compared with the traditional solution that only sets one lower support plate, this embodiment can avoid the front end of the bag fabric dragging on the worktable 100 when the bag fabric moves, reducing the wear of the front end of the bag fabric.

[0058] When sewing the outer fabric and the first layer of bag fabric, the operator places the second layer of bag fabric on another rear support plate 500 at the bag fabric loading station 110. After the sewing station 120 completes the sewing of the first layer of bag fabric, the first gripping component 600 releases the rear support plate 500 below the material fixing mechanism 200, and the rear support plate 500 is removed from the sewing station 120. During the process of the material fixing mechanism 200 moving back to the bag fabric loading station 110 to pick up the second layer of bag fabric, the second gripping component 700 can hold the front support plate 400 to prevent the front end of the first layer of bag fabric from bending and folding onto the part of the second layer of bag fabric to be sewn. After the material fixing mechanism 200 reaches the bag fabric loading station 110, the second gripping component 700 releases the front support plate 400, and the first gripping component 600 grips the rear support plate 500 containing the second layer of bag fabric, carrying the second layer of bag fabric to the sewing station 120 for sewing the second layer of bag fabric. At this point, the operator can place the next first-layer bag fabric on the rear support plate 500 and the new front support plate 400, in preparation for the next bag processing.

[0059] Therefore, this embodiment can reduce wear and tear when the first layer of bag fabric moves during the bag processing process, and when processing genuine bags with two layers of bag fabric, the first layer of bag fabric is less likely to bend and fold into the part of the second layer of bag fabric to be sewn, thereby reducing the defect rate of bag processing, improving the processing quality of the bag opening machine, and reducing the waste of raw materials and labor.

[0060] Preferably, a tray reset device can also be provided on the workbench 100. The tray reset device can be as described in Chinese Utility Model Patent No. CN214060872U, which uses a clamping mechanism to clamp the rear tray 500 after the bag fabric sewing is completed and move the rear tray 500 to the rear of the bag fabric feeding station 110, so that the rear tray 500 enters the positioning state. After the rear tray 500 on the bag fabric feeding station 110 is removed, the rear tray 500 in the positioning state can enter the bag fabric feeding station 110 to prepare for the next bag fabric feeding.

[0061] Reference Figures 2 to 4 In this embodiment, the first gripping component 600 includes a first pneumatic gripper connected to the material setting mechanism 200. The rear support plate 500 is provided with a first protrusion 530 for gripping by the first pneumatic gripper. The material setting mechanism 200 grips the rear support plate 500 by gripping the first protrusion 530 on the rear support plate 500 with the first pneumatic gripper.

[0062] Specifically, in this embodiment, the first pneumatic gripper is positioned behind the material-fixing mechanism 200 and connected to the side of the movable seat 300 opposite to the material-fixing mechanism 200, with the gripping end of the first pneumatic gripper facing downwards. Two first pneumatic grippers are provided, spaced apart in the left-right direction (where left-right refers to the horizontal direction perpendicular to the front-back direction). Correspondingly, two first protrusions 530 are provided on the rear support plate 500 in the left-right direction. The two pneumatic grippers stably grip and hold the rear support plate 500 in the left-right direction, facilitating the movement of the rear support plate 500 in the left-right direction.

[0063] In addition, in other embodiments, the first pneumatic gripper may be configured in other quantities or in other installation forms, as long as it can grip the first protrusion 530.

[0064] In other embodiments, the first gripping component 600 can also employ other suitable mechanisms, such as a suction cup or an electromagnet 240, with a corresponding suction cup adsorption area or magnetic adsorption area provided on the rear support plate 500. Compared to other clamping solutions, this embodiment uses a gripper gripping method, which facilitates control of the air path and thus controls the gripping or releasing of the rear support plate 500. This technology is mature and has a low cost.

[0065] In this embodiment, the first pneumatic gripper is vertically slidably mounted on the movable seat 300 by being driven by a vertically arranged cylinder, so that the first pneumatic gripper can vertically lift and lower to grip the first protrusion 530. In addition, in other embodiments, the first pneumatic gripper can also be directly connected to the lower pressure frame 210 of the material fixing mechanism 200.

[0066] Reference Figures 2 to 4The second gripping component 700 includes a second pneumatic gripper connected to the material fixing mechanism 200. The front support plate 400 is provided with a second protrusion 410 for gripping by the second pneumatic gripper. The material fixing mechanism 200 grips the front support plate 400 by gripping the second protrusion 410 on the rear support plate 500 with the second pneumatic gripper.

[0067] In this embodiment, the second pneumatic gripper is connected to the left end of the pressure frame 210 (i.e., the end of the pressure frame 210 near the bag fabric feeding station 110). The pressure frame 210 is provided with two second pneumatic grippers spaced apart in the front-back direction, and correspondingly, the front support plate 400 is provided with two second protrusions 410 spaced apart in the front-back direction, so that the second pneumatic grippers can grip the front support plate 400 more stably when moving it left and right.

[0068] In addition, in other embodiments, the second pneumatic gripper may be configured in other quantities or in other installation forms, as long as it can grip the second protrusion 410.

[0069] In other embodiments, the second gripping component 700 can also employ other suitable mechanisms, such as a suction cup or an electromagnet 240, with a corresponding suction cup adsorption area or magnetic adsorption area provided on the front support plate 400. Compared to other clamping solutions, this embodiment uses a gripper gripping method, which facilitates control of the air path and thus controls the gripping or releasing of the front support plate 400. This technology is mature and has a low cost.

[0070] Reference Figure 3 A magnet 240 is fixedly disposed on the lower side of the material fixing mechanism 200. In this embodiment, the magnet 240 is specifically fixedly disposed on the lower side of the pressure frame 210. The front support plate 400 has a magnetic attraction part for the magnet 240 to attract it. The material fixing mechanism 200 uses the magnet 240 to attract the magnetic attraction part on the front support plate 400, making the material fixing mechanism 200 more stable when gripping the front support plate 400 and moving the front support plate 400.

[0071] Specifically, in this embodiment, the front support plate 400 is made of ferromagnetic metal, and the position of the front support plate 400 corresponding to the magnet 240 is the magnetic attraction part for the magnet 240 to attract. In other embodiments, the front support plate 400 can also be made of other materials, as long as a magnetic attraction part made of ferromagnetic material is provided at the position corresponding to the magnet 240.

[0072] In this embodiment, multiple magnets 240 are provided, and the multiple magnets 240 are arranged at intervals in the left and right direction so that the magnets 240 can stably magnetically attract the front support plate 400 along the length direction of the front support plate 400. The front support plate 400 is more stable when it moves left and right with the material fixing mechanism 200, and it is less likely that the part away from the second gripping component 700 will lift up.

[0073] Reference Figure 1The bag fabric feeding station 110 is equipped with a locking mechanism 800, which is located on the edge of the front support plate 400. The locking mechanism 800 can lock and fix the front support plate 400 at the bag fabric feeding station 110, or release the locking of the front support plate 400 at the bag fabric feeding station 110. Thus, when the material fixing mechanism 200 is not gripping the front support plate 400, the front support plate 400 can be securely locked and fixed at the bag fabric feeding station 110, making it convenient for the user to place the bag fabric on the front support plate 400, and at the same time, it is convenient for the material fixing mechanism 200 to position and grip the front support plate 400; when the material fixing mechanism 200 grips the front support plate 400, the locking mechanism 800 releases the locking of the front support plate 400, so that the material fixing mechanism 200 can drive the front support plate 400 to move.

[0074] In this embodiment, the locking mechanism 800 is located at the left end of the front support plate 400 (i.e., the end of the front support plate 400 away from the material fixing mechanism 200) to avoid interference when the material fixing mechanism 200 moves, or to avoid affecting the operator's operation of the bag opening machine. In addition, in other embodiments, the locking mechanism 800 may also be located at the front end, rear end or right end of the front support plate 400.

[0075] Reference Figure 5 and Figure 6 In this embodiment, the locking mechanism 800 includes a locking cylinder 810 and a locking pressure plate 820. The locking cylinder 810 is vertically arranged, and the cylinder body of the locking cylinder 810 is fixedly arranged on the worktable 100. The piston rod of the locking cylinder 810 is connected to the locking pressure plate 820, and at least part of the locking pressure plate 820 extends above the front support plate 400.

[0076] When the piston rod of the locking cylinder 810 moves, it drives the locking pressure plate 820 to move downwards and press against the front support plate 400, thus pressing the front support plate 400 firmly onto the worktable 100 and locking the front support plate 400 in place. When the piston of the locking cylinder 810 moves in the reverse direction, it drives the locking pressure plate 820 to move upwards and disengage from the front support plate 400, thereby releasing the locking of the front support plate 400. This locking mechanism 800 is designed to facilitate control of the clamping mechanism to lock or disengage the front support plate 400, and the locking of the locking pressure plate 820 is relatively secure and reliable.

[0077] In addition, in other embodiments, the locking cylinder 810 can be replaced with a linear drive component such as a motor lead screw.

[0078] In other embodiments, the locking cylinder 810 may also be horizontally positioned to drive the locking pressure plate 820 to move horizontally onto or off the front support plate 400.

[0079] Reference Figure 5 and Figure 6In this embodiment, a clearance groove 130 is provided on the workbench 100. A cover plate 140 is detachably and fixedly connected to the opening of the clearance groove 130 by screws, and the cover plate 140 covers the opening of the clearance groove 130. The cylinder body of the locking cylinder 810 passes through the clearance groove 130 and is located below the cover plate 140, and the cylinder body of the locking cylinder 810 is fixed to the cover plate 140 by screws or other connecting parts. A notch is provided on the cover plate 140, and the piston rod of the locking cylinder 810 extends out of the notch of the cover plate 140 and connects with the locking pressure plate 820.

[0080] In this embodiment, a rotating support 830 is provided between the piston rod of the locking cylinder 810 and the front support plate 400. The upper end of the rotating support 830 is rotatably connected to the locking pressure plate 820 along the vertical plane, and the lower end of the rotating support 830 is rotatably connected to the worktable 100 along the vertical plane. The piston rod of the locking cylinder 810 is rotatably connected to the locking pressure plate 820 along the vertical plane.

[0081] Reference Figure 7 When the piston rod of the locking cylinder 810 pulls the locking plate 820 downward, the locking plate 820 can rotate in the vertical plane with the rotating support 830 as the fulcrum. This causes the portion of the locking plate 820 away from the piston rod of the locking cylinder 810 to rotate upward and tilt away from the front support plate 400, thus releasing the locking of the front support plate 400. (Refer to...) Figure 8 When the piston rod of the locking cylinder 810 pushes the locking plate 820 upward, the locking plate 820 can rotate in the vertical plane with the rotating support 830 as the fulcrum. As a result, the part of the locking plate 820 away from the piston rod of the locking cylinder 810 rotates downward to press on the front support plate 400, thereby achieving the locking and fixing of the front support plate 400.

[0082] Therefore, in this embodiment, the locking plate 820 moves closer to or further away from the front support plate 400 by rotating. When the locking plate 820 rotates away from the front support plate 400, the vertical projection area of ​​the locking plate 820 on the front support plate 400 gradually decreases until the vertical projection of the locking plate 820 does not overlap with the front support plate 400. This ensures that the locking plate 820 will not interfere with the vertical movement of the front support plate 400 from above, which is beneficial for the material fixing mechanism 200 to move vertically after grabbing the front support plate 400.

[0083] Reference Figures 5 to 8 In this embodiment, the rotating support 830 is connected to the cylinder body of the locking cylinder 810, thereby connecting the rotating support 830 to the worktable 100 via the locking cylinder 810. A connecting protrusion 840 protrudes from the upper side of the cylinder body of the locking cylinder 810, and the lower pivot of the rotating support 830 is connected to the connecting protrusion 840, achieving a rotatable connection between the rotating support 830 and the locking cylinder 810. Furthermore, in other embodiments, the rotating support 830 can also be directly connected to the worktable 100.

[0084] In addition, in other embodiments, the rotating support 830 may not be provided, and the piston rod of the locking cylinder 810 may be fixedly connected to the locking pressure plate 820. The locking cylinder 810 can directly drive the locking pressure plate 820 to move vertically to approach or move away from the front support plate 400.

[0085] In this embodiment, a locking block 420 protrudes upward from one end of the front support plate 400 near the locking mechanism 800, and a limiting protrusion 821 protrudes downward from the front end of the locking pressure plate 820. When the locking pressure plate 820 presses against the front support plate 400, the limiting protrusion 821 blocks the side of the locking block 420 away from the locking cylinder 810, thereby limiting the front support plate 400 and preventing it from moving away from the locking cylinder 810, making the front support plate 400 more securely locked.

[0086] Preferably, in some embodiments, a locking mechanism 800 may be provided at the edge of the rear support plate 500 to lock and unlock the rear support plate 500, so as to prevent the rear support plate 500 from shifting at the bag fabric feeding station 110, which is beneficial for the first gripping component 600 to grip the rear support plate 500.

[0087] Reference Figure 4 and Figure 6 An outer protective cover 150 is fixedly installed on the workbench 100. The outer protective cover 150 surrounds the locking pressure plate 820 and has openings on both the left and right sides to allow the locking pressure plate 820 to extend and move. The protective cover protects the locking pressure plate 820 from being pinched by the locking pressure plate 820 when its working area is entered. At the same time, the outer protective cover 150 also serves as a positioning structure for the front support plate 400, blocking the front support plate 400 at the end facing the locking cylinder 810 and preventing it from moving closer to the locking cylinder 810.

[0088] Reference Figure 4 and Figure 6 The workbench 100 is provided with a positioning block 160, which abuts against the end of the front support plate 400 facing the locking mechanism 800, so that the end of the front support plate 400 can be quickly positioned, making the front support plate 400 accurately placed, and facilitating the second clamping component on the material setting mechanism 200 to grip the front support plate 400.

[0089] The working principle of the pallet device in this embodiment is as follows: The outer fabric is fixed on the material fixing mechanism 200, and the first layer of bag fabric is placed on the front support plate 400 and the rear support plate 500. After the bag opening of the outer fabric is cut and folded, there is a vertical movement distance between the material fixing mechanism 200 and the workbench 100. The material fixing mechanism 200 moves horizontally to the bag fabric loading station 110, so that the first pneumatic gripper is aligned with the first protrusion 530 and the second pneumatic gripper is aligned with the second protrusion 410. The material fixing mechanism 200 moves downward. At this time, the first gripping component 600 grips the rear support plate 500, the second gripping component 700 grips the front support plate 400, and the locking mechanism 800 unlocks the front support plate 400. Then the material fixing mechanism 200 moves upward first, and then drives the front support plate 400 and the rear support plate 500 to move horizontally to the sewing station 120 to sew the first layer of bag fabric under the outer fabric.

[0090] After sewing is completed, the first gripping component 600 releases the rear support plate 500, and the rear support plate 500 exits from the sewing station 120 and enters the positioning state; the second layer of bag fabric is placed on another rear support plate 500 on the bag fabric loading station 110, the second gripping component 700 holds the front support plate 400, the material fixing mechanism 200 carries the sewn face fabric, the first layer of bag fabric and the front support plate 400 to the bag fabric loading station 110, the material fixing mechanism 200 moves down so that the front support plate 400 is placed on the bag fabric loading station 110, the second gripping component 700 releases the front support plate 400 and the locking mechanism 800 locks the front support plate 400, and at the same time the first gripping component 600 grips the rear support plate 500. Then the material setting mechanism 200 moves upward, and drives the face fabric, the first layer of bag fabric, the second layer of bag fabric and the rear support plate 500 to the sewing station 120 to sew the second layer of bag fabric. The rear support plate 500, in its position, enters the bag fabric loading station 110. At this time, the first layer of bag fabric required for the next processing can be placed on the rear support plate 500 and the front support plate 400, ready for the next processing.
