Technical Field

[0001] This invention relates to the field of bag processing technology, specifically to a surface treatment device and process for bag production. Background Technology

[0002] Suitcases (also known as rolling suitcases) are essential equipment for daily travel and business trips. Their core values ​​are "safe storage, convenient carrying, and durability". Their design revolves around four core needs: "storage capacity, mobility, durability, and portability". Traditional plastic suitcases are made using vacuum forming. After forming, workers need to place the material on a mold and then use a cutting device to trim the edges. Because manual positioning is used in this process, the edges of the material are prone to being cut unevenly. This can easily lead to the material edges scratching people during subsequent processing. Moreover, after cutting, the material includes finished and unfinished parts, which workers need to lift and remove in turn to complete the unloading process, making the operation quite inconvenient. Summary of the Invention

[0010] To facilitate the transfer of waste materials, the present invention is improved by symmetrically arranging waste material unloading components on the front and rear sides of the base. Each waste material unloading component includes a hinge frame, a hinge shaft, a hinge frame, and a third motor. The hinge frame is symmetrically arranged on the front and rear sides of the base, and a hinge shaft is rotatably mounted on the hinge frame. The hinge frame is U-shaped, and the free end of the hinge frame is located between the corresponding limiting seat and the bearing block. The hinge frame is connected to the hinge shaft. The output end of the third motor passes through the hinge frame and is connected to the hinge shaft. Guide frames are symmetrically arranged on the left and right sides of the hinge frame. The guide frames are L-shaped and are located at the end near the hinge shaft.

[0011] To facilitate waste collection, the present invention is improved by providing a waste collection component below the workbench. The waste collection component includes a waste frame, casters, and brakes. The waste frame is located below the workbench, and several sets of casters are located below the waste frame. Brakes are provided on the periphery of the corresponding casters.

[0012] To facilitate the adjustment of material height and positioning, the present invention is improved in that the limiting adjustment component includes a negative pressure tube, a suction cup, a lifter, and a lifting plate. The lifter is provided above the middle part of the base, and the lifting plate is provided above the lifter. Several sets of negative pressure tubes are also provided above the base, and suction cups that contact the top wall of the material are provided on the negative pressure tubes.

[0013] The present invention further provides a surface treatment process for bag manufacturing, comprising the following steps: Step 1: The front and rear feed components drive the slide plate to the front of the worktable, the lift is in the retracted state, the waste unloading component is in the horizontal state, and the pusher is in the retracted state. At this time, the push plate does not contact the inclined block. The material with the lower edge is placed on the four sets of limit seats and pressed down until the four sets of negative pressure pipes cooperate with the suction cup to adsorb the inner top wall of the material. Step 2: The front and rear feed components move the slide plate towards the rear of the worktable. At this time, the left and right feed components drive the horizontal cutting component to the position of cutting one edge of the material. The first cutter is started. As the slide plate continues to feed towards the rear of the worktable, after the output end of the first cutter has cut one edge of the material, the front and rear feed components drive the slide plate to stop. The left and right feed components drive the horizontal cutting component to move. After the output end of the first cutter has cut the front edge of the material, the left and right feed components drive the horizontal cutting component to stop. The driver rotates in the opposite direction. After the output end of the first cutter has cut the other edge of the material, the front and rear feed components drive the slide plate to stop. The left and right feed components drive the horizontal cutting component to reset. After the horizontal cutting component has cut the rear edge of the material, the front and rear feed components drive the slide plate to continue moving forward. Step 3: The front and rear feed components move the slide plate to the middle part of the two sets of second cutter output ends and stop. The negative pressure pipe is closed, and the lifter is started. The lifter moves the lifting plate up, and the finished material rises. The lower edge of the finished material slides and connects with the limit seat. The pusher is started, and the pusher moves the push plate towards the center of the worktable. The push plate squeezes the inclined block, and the inclined block moves the lower pressure block down. The edge of the waste material is clamped between the bearing block and the friction block. With the support of the limit seat, the second cutter is started. As the pusher continues to feed, the output end of the second cutter cuts the edge of the waste material and the waste frame. The output end of the second cutter is located between the finished material and the base. Step 4: After the waste material is cut, the pusher is reset. At this time, the push plate no longer limits the inclined block. The tension spring drives the lower pressure block to rise. The friction block is located above the edge of the waste material. The front and rear feed components drive the slide plate to move a certain distance to the front of the worktable. The third motor is started. The third motor drives the hinge rod to rotate. The hinge frame rotates in conjunction with the guide frame. The hinge frame rotates a certain angle, and the waste material falls from the hollow hole into the waste material collection component. Step 5: The front and rear feed components drive the slide plate to reset. At this time, the lifter drives the lifting plate to rise, and the bottom wall of the finished material is higher than the limit seat, which makes it convenient for the staff to unload the material. Then the lifter resets and waits for the next material assembly.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a surface treatment apparatus and process for bag production, which has the following beneficial effects: The surface treatment device and process for bag production includes a limiting seat (arranged at four corners) to circumferentially limit the material, a bearing block to support the lower edge of the material, and a negative pressure tube in conjunction with a suction cup to adsorb the inner top wall of the material, thus completing the positioning of the material. During the cutting process, the stability of the material is ensured, thereby ensuring the cutting quality. During vertical cutting, the pressing component squeezes the inclined block through the push plate, causing the pressing block and friction block to clamp the edge of the waste material. This ensures that the material does not shake during cutting and avoids waste splashing. In conjunction with the waste unloading component, it is convenient to unload and transfer the waste material set on the four sets of limit seats. Afterwards, only the staff needs to unload the lifted finished material. Attached Figure Description

The vertical cutting assembly also includes The device includes a pressing assembly, which comprises a crossbeam 15, a reset component, an inclined block 16, a pressing block 17, and a friction block 18. The side plate 9 has crossbeams 15 symmetrically arranged at its front and rear ends near the hollow hole. The pressing block 17 is inverted L-shaped. The friction block 18 is arranged below the pressing block 17 near the middle of the hollow hole. A reset component connected to the crossbeam 15 is also arranged above the pressing block 17. An inclined block 16 that can penetrate the crossbeam 15 is arranged at one end of the pressing block 17 near the side plate 9. The push plate 11 is slidably connected to the crossbeam 15. The first mounting plate 8 is arranged between the two sets of crossbeams 15. The friction block 18 is arranged above the bearing block 14.

The upper and lower ends of the tension spring 19 and the telescopic rod 20 are respectively connected to the crossbeam 15 and the pressing block 17. After the material is assembled and positioned, the front and rear feed components drive the slide plate 3 to move backward. During this process, the pusher 10 is in a retracted state, and the vertical cutting component is in a standby state. The vertical cutting component will not interfere with the movement of the material or the supporting component. Initially, the left and right feed components drive the first mounting plate 8 to one side of the material. At this time, the output end of the first cutter 6 is matched with the retraction groove on one side of the material. As the slide plate 3 moves backward, the first cutter 6 is started. The first cutter 6 first cuts one side of the material. At this time, the material is located behind the worktable 1. The front and rear feed components drive the slide plate 3 to stop. The left and right feed components are started. The left and right feed components drive the first mounting plate 8 to move laterally. The output end of the first cutter 6 cuts the front side of the material. Then, the left and right feed components drive the first mounting plate 8 to stop.

The third motor 36 (the third motor 36 is a stepper motor) is started, which drives the hinge shaft 34 to rotate. The two sets of hinge shafts 34 rotate in opposite directions, and the hinge frame 35 changes from a horizontal state to an upward tilt. At this time, the cut waste frame 38 can slide down along the hinge frame 35 and the guide frame 37 and fall into the waste collection component.

The lifter 43 continues to rise, driving the lifting plate 44 to move up synchronously with the finished product, so that the bottom wall of the finished product is higher than the limit seat 5 (height difference ≥10mm). The staff can directly take out the finished product without additional disassembly. Then the lifter 43 returns to the initial loading state, waiting for the next processing cycle.

[0021] The present invention further provides a surface treatment process for bag manufacturing, comprising the following steps: Step 1: The front and rear feed components drive the slide plate 3 to the front of the workbench 1, the lift 43 is in the retracted state, the waste material unloading component is in the horizontal state, and the pusher 10 is in the retracted state. At this time, the push plate 11 does not contact the inclined block 16. The material with the lower edge is placed on the four sets of limit seats 5 and pressed down until the four sets of negative pressure pipes 41 cooperate with the suction cup 42 to adsorb the inner top wall of the material. Step 2: The front and rear feed components drive the slide plate 3 to move towards the rear of the worktable 1. At this time, the left and right feed components drive the horizontal cutting component to the position of cutting one edge of the material. The first cutter 6 is started. As the slide plate 3 continues to feed towards the rear of the worktable 1, after the output end of the first cutter 6 has finished cutting one edge of the material, the front and rear feed components drive the slide plate 3 to stop. The left and right feed components drive the horizontal cutting component to move. After the output end of the first cutter 6 has finished cutting the front edge of the material, the left and right feed components drive the horizontal cutting component to stop. The driver rotates in the opposite direction. After the output end of the first cutter 6 has finished cutting the other edge of the material, the front and rear feed components drive the slide plate 3 to stop. The left and right feed components drive the horizontal cutting component to reset. After the horizontal cutting component has finished cutting the rear edge of the material, the front and rear feed components drive the slide plate 3 to continue to move forward. Step 3: The front and rear feed components move the slide plate 3 to the middle part of the output end of the two sets of second cutters 13 and stop. The negative pressure pipe 41 is closed and the lifter 43 is started. The lifter 43 drives the lifting plate 44 to rise, and the finished material rises. The lower edge of the finished material slides and connects with the limit seat 5. The pusher 10 is started. The pusher 10 drives the push plate 11 to move towards the center of the worktable 1. The push plate 11 squeezes the inclined block 16. The inclined block 16 drives the lower pressure block 17 to move downward. The edge of the waste material is clamped between the bearing block 14 and the friction block 18, and supported by the limit seat 5. The second cutter 13 is started. As the pusher 10 continues to feed, the output end of the second cutter 13 cuts the edge of the waste material and the waste frame 38. The output end of the second cutter 13 is located between the finished material and the base 4. Step 4: After the waste material is cut, the pusher 10 is reset. At this time, the pusher plate 11 no longer limits the inclined block 16. The tension spring 19 drives the lower pressure block 17 to rise. The friction block 18 is located above the edge of the waste material. The front and rear feed components drive the slide plate 3 to move a certain distance to the front of the worktable 1. The third motor 36 is started. The third motor 36 drives the hinge rod to rotate. The hinge frame 35 rotates in conjunction with the guide frame 37. The hinge frame 35 rotates a certain angle, and the waste material falls from the hollow hole into the waste material collection component. Step 5: The front and rear feed components drive the slide plate 3 to reset. At this time, the lifter 43 drives the lifting plate 44 to rise. The bottom wall of the finished material is higher than the limit seat 5, which makes it convenient for the staff to unload the material. Then the lifter 43 resets and waits for the next material assembly.
