TECHNICAL FIELD

[0001] The utility model relates to a bag cutting mechanism device technical field especially relates to a cutting device for bag raw materials. BACKGROUND

[0002] As the general term of various bagged articles, bags cover shopping bags, handbags, handbags, wallets, backpacks, single-shoulder bags, crossbody bags, waist bags and various trolley cases and other diversified packaging forms.

[0003] In the practical application of bags, functionality, practicality and aesthetics are the three indispensable elements. Therefore, most bag designs include an inner lining layer, which not only improves the aesthetics of the bag, but also has multiple functions such as wear resistance and stain resistance. In particular, due to the special requirements of the inner lining layer for the curvature value, the edge is usually designed as an irregular shape to ensure that a regular appearance can be formed after bending to meet the use requirements.

[0004] Currently, the cutting technology for bag linings mainly includes laser cutting and die cutting processes. Although the die cutting process is traditional and less efficient, it has strong adaptability to complex structures, so it is still widely used in the processing of bag linings with high precision requirements.

[0005] The processing equipment using a die for cutting usually has a simple structure, mainly composed of a support plate, a hydraulic mechanism and a die. In the operation process, multiple layers of base material are stacked above the support plate, and the die is located above the base material. The die is moved to complete the cutting work by applying pressure through the hydraulic mechanism.

[0006] It is worth noting that the size of the die is usually not large enough to cover the entire base material, so it is mainly suitable for processing small linings. During the processing, the die needs to be moved constantly to complete multiple cutting of the base material. The movement path of the die completely depends on the skill level of the operator, and the shorter the movement distance, the less waste will be generated subsequently.

[0007] In view of this, the present research proposes a new type of bag raw material cutting device, which aims to assist the operator in accurately positioning the die to reduce the waste generated in the multiple processing process. INVENTION CONTENTS

DETAILED DESCRIPTION

[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of the present application.

[0025] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0026] Please refer to Figure 1 A device for cutting bag raw materials, which is consistent with the device in the prior art. The device comprises a support plate 1, and a plurality of layers of base materials 2 to be processed are sequentially stacked on the support plate 1.

[0027] Therefore, above these base materials 2, a cutter die 4 for cutting operation is arranged.

[0028] It is particularly worth noting that in actual application, a corresponding hydraulic mechanism (not shown in the figure) is also provided above the base materials 2 and the cutter die 4. The hydraulic mechanism makes the cutter die 4 sink into the plurality of layers of base materials 2 by applying pressure, thereby achieving cutting of the base materials 2 and completing the cutting process.

[0029] In addition, as Figure 1 shown, the thickness of the support plate 1 is designed to be relatively thick. This design mainly takes into account that in actual use, the support plate 1 is usually made of wood material, and the relatively thick support plate 1 can absorb the impact force in the pressure application process of the hydraulic mechanism, preventing the cutter die 4 from being deformed or damaged due to bearing excessive reaction force.

[0030] Referring to Figure 2 and Figure 3 Compared with the prior art, the technical device adds a positioning pipe 5, and a driven ring is sleeved outside the positioning pipe 5.

[0031] In addition, one side of the driven ring is fixedly connected with a limiting rod 3. By placing the limiting rod 3 above the base materials 2 and making it contact with the side end of the cutter die 4, the limiting rod 3 can be used to assist the cutter die 4 in accurate positioning, thereby effectively reducing the waste generated in the cutting process.

[0032] Specifically, as Figure 2As shown, the device is provided with a driving block 9 inside the positioning tube 5, and the driving block 9 is connected with the driven ring through magnetic mode. Therefore, by adjusting the position of the driving block 9, the position of the driven ring can be changed synchronously, so as to realize the adjustment of the position of the limiting rod 3.

[0033] In addition, the outer side of the driving block 9 is provided with a sealing ring 8, so as to ensure that the driving block 9 and the positioning tube 5 are connected in a sealed mode. In actual application, since the driving block 9 and the positioning tube 5 are connected in a sealed mode, the position of the driving block 9 can be adjusted by changing the air pressure difference on both sides of the driving block 9.

[0034] It must be pointed out that, as shown in Figure 3 , Figure 5 In actual application, in order to avoid the position conflict between the limiting rod 3 and the corresponding hydraulic mechanism, so as to cause the damage of the limiting rod 3, the device is provided with a synchronous part 11 outside each axial end of the positioning tube 5. The lower end of the synchronous part 11 is fixedly connected with the slide rod 12, and the upper end is fixedly connected with the driving plate 10.

[0035] In this case, the driving plate 10 is constrained above the base 2, and the projection of the driving plate 10 on the horizontal plane coincides with the projection of the base 2 on the horizontal plane. Therefore, when the hydraulic mechanism drives the die 4 to move downward, the hydraulic mechanism will press the driving plate 10 synchronously. At this time, the driving plate 10 will drive the synchronous part 11, the positioning rod and the limiting rod 3 to move downward.

[0036] In addition, the existence of the driving plate 10 also helps to fix the position of the base 2, so as to ensure that the base 2 is subjected to multi-point force, and avoid the displacement of the base 2 in the process of pressing the die 4.

[0037] Further, the outer side of the slide rod 12 is provided with a limiting plate 14, and the limiting plate 14 is slidingly connected with the slide rod 12. This design realizes the fixation of the horizontal position of the synchronous part 11, i.e. the positioning tube 5.

[0038] Therefore, the device is provided with a compression spring II 13 at the upper end of the limiting plate 14, and the two ends of the compression spring II 13 are in contact with the limiting plate 14 and the synchronous part 11 respectively, so as to assist the positioning tube 5, i.e. the limiting rod 3 to reset, and facilitate the limiting rod 3 to continuously limit the die 4.

[0039] Specifically, as shown in Figure 1 , Figure 3 The device is provided with a gas storage tank 6 below the positioning tube 5, and a control valve is arranged between the axial end of the positioning tube 5 and the gas storage tank 6. The input end of the control valve is in communication with the gas storage tank 6, and the output end of the control valve is in communication with the positioning tube 5. Therefore, by opening and closing the control valve, the gas inside the gas storage tank 6 can be transferred to the positioning tube 5, so as to change the air pressure values on both sides of the driving block 9.

[0040] Further, the device is configured with a control valve at each axial end of the positioning pipe 5, and the input end of each control valve is connected to the gas tank 6, and the output end is connected to the positioning pipe 5. In this configuration, the two control valves work together to adjust the pressure change on both sides of the drive block 9, thereby controlling the moving direction of the drive block 9.

[0041] Therefore, the device is configured with a ball valve 15 between each control valve and the gas tank 6, and the input end of the ball valve 15 is connected to the corresponding gas tank 6, and the output end is connected to the input end of the corresponding control valve. Through the control of the ball valve 15, the precise management of the gas flow can be realized.

[0042] In actual application, the working state of the two control valves remains consistent. Therefore, by closing the ball valve 15 on one side and opening the ball valve 15 on the other side, it can be ensured that the gas inside the gas tank 6 only flows in one direction when the two control valves are opened at the same time, thereby realizing the directional movement of the drive block 9.

[0043] Specifically, as shown in the figure, Figure 4 The control valve is composed of an outer shell 7, and a flow-through cavity and a limiting cavity are provided in the outer shell 7. The diameter of the limiting cavity is smaller than that of the flow-through cavity, and it is located above the flow-through cavity.

[0044] In addition, a through hole I 19 is provided below the limiting cavity, which connects the limiting cavity with the positioning pipe 5. A through hole II 21 is provided below the flow-through cavity, which connects the flow-through cavity with the gas tank 6.

[0045] Therefore, the device is provided with a slidable blocking block 18 inside the flow-through cavity, and the projection of the blocking block 18 on the horizontal plane is circular, and its diameter is larger than that of the limiting cavity. When the blocking block 18 moves upward to the state of contacting the inner wall of the outer shell 7, it can prevent the gas from entering the limiting cavity from the flow-through cavity of the outer shell 7, thereby limiting the gas from entering the positioning pipe 5 from the gas tank 6, at this time the control valve is in the closed state. Correspondingly, when the blocking block 18 moves downward to the state of contacting the inner wall of the outer shell 7 is removed, the gas can change its position through the flow-through channel between the blocking block 18 and the inner wall of the outer shell 7, at this time the gas can enter the positioning pipe 5 from the gas tank 6, that is, the control valve is in the open state.

[0046] Further, the lower end of the blocking block 18 is provided with a compression spring I 20, and the two ends of the spring are respectively in contact with the blocking block 18 and the inner wall of the outer shell 7.

[0047] Therefore, when the compression spring 120 is not subjected to external force, the blocking block 18 is in contact with the inner wall of the outer shell 7, thereby ensuring that the blocking block 18 is in contact with the inner wall of the outer shell 7 under normal circumstances, i.e. the control valve is in a closed state under normal circumstances. This design ensures that the control valve can only be opened controllably when necessary, i.e. after each cutting operation is completed, and the position of the driving block 9 is adjusted by increasing the air pressure value on one side of the driving block 9.

[0048] In addition, the projection of the blocking block 18 in the vertical direction is in a trapezoidal structure, i.e. the upper end diameter is smaller than the lower end diameter. Therefore, when the compression spring 120 is not subjected to external force, the upper end of the blocking block 18 can be embedded in the limiting cavity. This design ensures that there is sufficient contact area between the blocking block 18 and the inner wall of the outer shell 7 under the closed state of the control valve, thereby enhancing the gas blocking performance. At the same time, by utilizing the physical characteristics of the trapezoidal structure, the position of the blocking block 18 can be accurately limited, preventing it from entering the limiting cavity and avoiding direct communication between the through hole 119 and the through hole 121.

[0049] Specifically, to achieve accurate position control of the blocking block 18, the device is fixedly installed with a follower rod 17 at the upper end of the blocking block 18, and a contact block 16 is fixedly installed at the upper end of the follower rod 17.

[0050] In addition, the contact block 16 is in sealed connection with the inner wall of the outer shell 7, so that the contact block 16 can move up and down linearly relative to the outer shell 7. This design ensures that when the control valve is in an open state, the gas in the gas tank 6 will not escape to the external environment through the gap between the contact block 16 and the outer shell 7, thereby ensuring that the gas can enter the positioning pipe 5 directly as expected.

[0051] At the same time, since the downward movement of the contact block 16 is the trigger condition for opening the control valve, and the contact block 16 is in sealed connection with the outer shell 7, in actual operation, when the contact block 16 is subjected to a downward pressure, the gas in the outer shell 7 is compressed. At this time, the through hole 121 synchronously inputs high-pressure gas into the inner part of the outer shell 7, ensuring that a large amount of gas is transported into the positioning pipe 5 in a short time, rapidly increasing the air pressure value on one side of the driving block 9. This measure ensures that the limiting rod 3 can quickly complete the position adjustment, thereby avoiding interference with the adjustment of the position of the cutting die 4 by the operator, and ensuring that the processing efficiency is not affected.

[0052] In addition, the device stipulates that the lower end surface of the sliding rod 12 and the upper end surface of the contact block 16 should be in close contact when neither the compression spring 120 nor the compression spring 113 is subjected to external force. This design can associate the cutting process with the opening process of the control valve, ensuring that the limiting rod 3 can automatically adjust its position after completing a cutting operation, thereby facilitating the continuity of the limiting of the cutting die 4.

[0053] In the actual operation of the device:

[0054] First, the operator can selectively open one of the ball valves 15 according to personal habits to determine the direction of travel of the drive block 9;

[0055] Next, the operator selects the appropriate cutter 4 and contacts the side end of the cutter 4 with the limiting rod 3, thereby completing the preliminary positioning of the cutter 4;

[0056] Subsequently, the hydraulic mechanism is pressed down to complete the initial cutting, during which the limiting rod 3 and the drive plate 10 move downward synchronously, and the control valve is opened;

[0057] After that, the hydraulic mechanism is moved upward to reset, during which the compression spring I 20 and the compression spring II 13 release the accumulated elastic potential energy, the control valve is closed, the limiting rod 3 loses the resistance from the base 2, and at this time the limiting rod 3 starts to move under the influence of the drive block 9;

[0058] Finally, the operator moves the cutter 4 so that it is again in contact with the limiting rod 3, and the above operations can be repeated to complete the continuous cutting work.

[0059] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
