[0001] The present invention relates to the technical field of handbag processing, and particularly relates to a film cutting device for handbag processing. Background Art

[0002] A handbag is a common packaging container, usually made of paper, plastic or cloth, with a design that is convenient to carry. A handbag is usually equipped with a pair of hand-held parts to facilitate consumers to pick up and carry, and is widely used in occasions such as shopping, promotional activities and gift packaging. Therefore, it is necessary to cut and press the raw materials of the handbag to form a handbag with a hand-held part.

[0003] In the prior art, production and processing are generally carried out in handbag manufacturers. With the gradual increase of existing workshops, the demand for handbags in individual workshops has gradually increased. Therefore, in the production process, manufacturers need to adapt to the handbags required by different individual workshops. However, existing manufacturers generally use raw material rolls with standard feeding specifications. Therefore, existing manufacturers do not produce handbags for individual workshops. For this reason, the raw materials purchased by the manufacturers are cut into non-standard raw materials according to the requirements of the workshops, and after the film cutting meets the requirements of the workshops, subsequent processing is carried out. Summary of the Invention

[0004] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a film cutting device for handbag processing, which solves the technical problem of low efficiency of existing raw material cutting.

Detailed implementation manner

[0018] For better explaining the present invention for easy understanding, the present invention will be described in detail below in conjunction with the accompanying drawings through specific implementation manners.

[0019] See the attached Figures 1 to 8 As shown, a film cutting device for handbag processing includes a workbench 1, a conveying mechanism 2, and a cutting mechanism 3. The conveying mechanism 2 includes two mounting plates longitudinally distributed along the workbench 1. The two mounting plates are oppositely arranged on the longitudinal two sides of the workbench 1. The conveying mechanism 2 is installed between the two mounting plates. The conveying mechanism 2 includes a first conveyor belt 21 and a second conveyor belt 22 on the same conveying plane. The first conveyor belt 21 is located at the front end of the mounting plate, and the second conveyor belt 22 is located at the rear end of the mounting plate. There is a gap between the first conveyor belt 21 and the second conveyor belt 22. The cutting mechanism 3 is located at the gap and is fixedly installed on the workbench 1. The cutting mechanism 3 has an annular cutting knife 31 that can reciprocate in the transverse direction. The annular cutting knife 31 protrudes upward relative to the first conveyor belt 21 to cut the raw material.

[0020] In this embodiment, a film cutting device for handbag processing is provided with a two-end structure for the conveying mechanism 2, and a cutting mechanism 3 is arranged between the first conveyor belt 21 and the second conveyor belt 22. The cutting mechanism 3 is located below the raw material. When the raw material passes through the cutting mechanism 3, the cutting mechanism 3 can cut the raw material from bottom to top. Moreover, the annular cutting knife 31 of the cutting mechanism 3 can reciprocate in the transverse direction to change the position of the annular cutting knife 31, so as to determine the cutting position of the raw material according to requirements, enabling the manufacturer to customize different handbags according to the needs of different customers.

[0021] Further, the cutting mechanism 3 includes a mounting frame 32, a mounting shaft 33 located inside the mounting frame 32, and at least one annular cutter 31 mounted on the mounting shaft 33. The mounting shaft 33 is detachably mounted on the shaft seats at both ends of the mounting frame 32 in the transverse direction. The annular cutter 31 can slide axially along the mounting shaft 33 and is positioned by a limiting component. By limiting the annular cutter from both ends respectively through the limiting component, the annular cutter can be prevented from moving axially. Moreover, compared with the existing bolt limiting, the limiting component can contact the annular cutter 31 over a large area, and the limiting component can cooperate with the arc-shaped mounting threaded strip 5 to achieve locking and positioning. While the positioning effect is good, it is convenient for installation and use.

[0022] It should also be noted that the diameters of both the annular cutter 31 and the limiting component are larger than that of the mounting shaft, and the diameter of the annular cutter 31 is slightly larger than that of the limiting component.

[0023] Further, the limiting component includes two limiting bodies 4 mounted on both sides of the annular cutter 31, and two arc-shaped mounting threaded strips 5 symmetrically arranged along the axial direction of the mounting shaft 33. The limiting body 4 can selectively contact and move away from the arc-shaped mounting threaded strip 5, so that the limiting body 4 can be axially positioned or slide along the mounting shaft 33. It should be noted that the arc-shaped mounting threaded strip 5 runs through the entire axial direction of the mounting shaft 33 and is located on two opposite sides of the mounting shaft 33. A ring structure can be formed between the two arc-shaped mounting threaded strips 5. In the locked state of the limiting body 4, the inner diameter of the limiting body 4 is exactly the same as the diameter of the ring structure formed between the two arc-shaped mounting threaded strips 5. At the same time, the internal thread of the limiting body 4 is just screwed with the external thread of the two arc-shaped mounting threaded strips 5 to axially position the limiting body 4. At the same time, the circumferential positioning is also achieved by the close fit between the limiting body 4 and the annular cutter 31. At the same time, circumferential positioning is carried out through the mounting spline on the circumference of the mounting shaft 33. Thus, the effect of the annular cutter 31 is better ensured.

[0024] Further, the limiting main body 4 includes an adjusting connecting body 41, a first adjusting half shell 42 and a second adjusting half shell 43. The first adjusting half shell 42 and the second adjusting half shell 43 are buckled together to form a receiving space capable of receiving the adjusting connecting body 41. A first notch slot 411 is provided at the position corresponding to the arc-shaped mounting threaded strip 5 on the adjusting connecting body 41. A sliding block 412 is movably mounted in the first notch slot 411. The sliding block 412 and the adjusting connecting body 41 together form an annular structural member. A threaded groove 413 screwed with the arc-shaped mounting threaded strip 5 is provided on the inner wall of the inner ring of the annular structural member. An arc-shaped inserting block 414 protrudes from the side of the sliding block 412 close to the first adjusting half shell 42, and the sliding block 412 can move radially outward or inward relative to the adjusting connecting body 41. Two annular slots 415 that are symmetrically arranged and cooperate with the second adjusting half shell 43 are provided on the annular end surface of the adjusting connecting body 41 close to the second adjusting half shell 43. An arc-shaped slot 416 that cooperates with the second adjusting half shell 43 is provided on each sliding block 412. The arc-shaped slot 416 can extend towards the direction of the arc-shaped inserting block 414 into its interior. The two arc-shaped slots 416 and the two annular slots 415 together form an integral annular inserting slot. The arc-shaped inserting block 414 can be inserted into the first adjusting half shell 42 for positioning. By arranging the sliding block 412 and the arc-shaped inserting block 414 to cooperate with the first adjusting half shell 42 and the second adjusting half shell 43, the sliding block 412 is realized, and thus the threaded groove 413 is incomplete, so that the adjusting connecting body 41 and the arc-shaped mounting threaded strip 5 cannot be connected by mutual cooperation. At this time, the limiting main body 4 can be moved in the axial direction of the mounting shaft 33 (equivalent to the transverse direction of the conveying mechanism 2), and then the annular cutter can also move horizontally on the mounting shaft 33. When the annular cutter 31 moves to a suitable position, by manually pressing the arc-shaped inserting block 414, so that it enters the slideway groove 4212 of the first adjusting half shell 42. Thereby making the threaded groove 413 complete and axially positioning the complete annular cutter 31. The position of the annular cutter 31 can be adjusted quickly and conveniently to cooperate with cutting handbags with different requirements, and the adaptability is stronger.

[0025] Further, the first adjustment half shell 42 includes an annular end wall 421 and a cylindrical structure 422. The annular end wall 421 is provided with an open groove 4211 and a slide groove 4212 which are interconnected. The open groove 4211 is used to insert the arc-shaped plug-in block 414, and the slide groove 4212 is used to limit the arc-shaped plug-in block 414. The cylindrical structure 422 and the second adjustment half shell 43 are detachably installed. It should also be noted that the arc-shaped plug-in block 414 enters the position of the slide groove 4212 and is rotated clockwise to make it in a safe position. At the same time, when the overall limiting body 4 moves axially on the mounting shaft 33, the direction of screwing the limiting body 4 is limited and is required to be always in the clockwise direction. Once it is rotated counterclockwise, the arc-shaped plug-in block 414 will be out of the slide groove 4212. In order to avoid the secondary technical problem, the arc-shaped spring sheet 417 is provided to achieve the clamping to prevent it from moving.

[0026] Furthermore, the second adjusting half shell 43 includes an annular baffle 431 , a first arc-shaped plug-in plate 432 , a second arc-shaped plug-in plate 433 and two adjusting bodies 434 . The first arc plug-in plate 432 and the second arc plug-in plate 433 are both located on one side end surface of the annular baffle 431 close to the adjusting connector 41. Two second notch grooves 4311 are provided at the position of the annular baffle 431 opposite to the first notch groove 411. The two adjusting bodies 434 are respectively located in the two second notch grooves 4311, and a third arc plug-in block 4341 is provided on the side of the adjusting body 434 facing the sliding block 412. The first arc plug-in plate 432, the second arc plug-in plate 433 and the two third arc plug-in blocks 4341 form an annular connector, which can be plugged into the annular connector groove. The third arc plug-in block 4341 is plugged into the arc slot 416. When the arc plug-in block 414 is located in the slide groove 4212, the adjusting body 434 has a pre-tightening force. When the arc-shaped plug-in block 414 is located in the open groove 4211, the preload force adjustment body 434 can move radially outward relative to the annular baffle 431, so that the adjustment body 434 drives the sliding block 412 to move outward through the third arc-shaped plug-in block 4341, so that the inner wall thread groove 413 of the sliding block 412 is separated from the arc-shaped mounting thread strip 5.

[0027] It should be noted that see Figure 8 As shown, the adjustment body 434 has a pre-tightening force by setting the elastic member 435. Specifically, under normal conditions, the spring of the elastic member 435 is in a compressed state, and when the arc-shaped plug-in block 414 plugged by the third arc-shaped plug-in block 4341 is in the opening groove 4211, the adjustment body 434 can move outward relative to the radial direction of the annular baffle 431 due to the pre-tightening force.

[0028] Further, a through groove 4221 is provided on the cylindrical structural member 422 of the first adjusting half shell 42, and an arc-shaped spring piece 417 is provided on the circumferential side wall of the adjusting connecting body 41. The arc-shaped spring piece 417 can be engaged with the through groove 4221 by cooperation. When the overall limiting body 4 is screwed axially through the thread, the screwing direction can be unrestricted, and it can be screwed from any direction, with strong operability and a wide application range.

[0029] Further, the workbench 1 has a feeding port close to the first conveyor belt 21 and a discharging port close to the second conveyor belt 22. A pressing mechanism is provided at the feeding port of the workbench 1. The pressing mechanism includes a first pressing structural member 6 and a second pressing structural member 7 respectively located on both sides of the cutting mechanism 3. Both the first pressing structural member 6 and the second pressing structural member 7 can move downward to press the raw material to cooperate with the cutting. Pressing the raw material from above can make the cutting effect of the raw material better. The position and frequency of pressing are input by the console, and the part of input parameters belongs to the prior art and will not be elaborated here.

[0030] Further, the first pressing structural member 6 includes a pressing support 61 erected above the first conveyor belt 21, a driving mechanism 62 installed on the pressing support 61, a roller frame 63 connected to the extending end of the driving mechanism 62, and a pressing roller 64 rotatably installed on the roller frame 63. The driving mechanism 62 can extend downward to drive the roller frame 63 and the pressing roller 64, so that the pressing roller 64 abuts against the first conveyor belt 21. The pressing force can be adjusted to facilitate adapting to raw materials of different thicknesses.

[0031] Further, the length of the first conveyor belt 21 is less than the length of the second conveyor belt 22. The cutting effect is better.
