Description

Technical Field

[0001] The present invention relates to the technical field of lighter assembly, and particularly relates to a leather wrapping device for lighters. Background Art

[0002] A lighter is a small fire-taking device, mainly used for taking fire, smoking, and also for cooking and other fire-taking. The outer shell or gas tank of a lighter is mainly made of plastic and metal. After the plastic lighter shell is used for a long time, the material is prone to aging. Therefore, most plastic lighters are disposable lighters; while the outer shell or gas tank of a metal lighter has a long service life and is suitable for reusable lighters, and the materials are mostly copper and iron. However, the price of copper is relatively high, and the iron-based lighter shell often comes into contact with human hands and is easily stained by sweat and other substances, resulting in rust. In addition, the transformation cost of the metal shell is too high, which greatly limits the appearance of the lighter. Therefore, there are metal lighters wrapped with an outer skin. However, when manually wrapping the outer skin, the efficiency is low and the quality is not easy to control. When using a machine to automatically wrap the outer skin, the machine structure is complex, the volume is large, and the price is high. Summary of the Invention

[0003] In view of this, the present invention provides a leather wrapping device for lighters to solve the above technical problems.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A leather wrapping device for lighters includes a mounting base, a movable gas tank limiting component, a movable pressing component, and a leather wrapping component disposed in the mounting base. The mounting base has a receiving portion for placing the outer skin. The gas tank limiting component includes a fixed shaft for the gas tank to be sleeved. The leather wrapping component includes two rotating shafts and a bracket disposed between the two rotating shafts. At least one elastic floating bracket ejector rod is provided between the bracket and the mounting base. The bracket has an arc groove that fits the outer skin, and the rotating shaft has a pressing head for pressing the outer skin.

[0006] Further, both sides of the bracket are respectively connected with the corresponding driving card slots of the rotating shaft so that the rotating shaft and the bracket act synchronously.

[0007] Furthermore, the pressing head has an arc pressing surface. When the leather wrapping is completed, the center of the arc pressing surface coincides with the center of the arc groove.

[0008] Furthermore, the receiving portion of the mounting base is a positioning groove, a guide groove is provided at the bottom of the positioning groove, the bracket is located in the guide groove, and the rotating shaft is rotatably matched with the corresponding rotating shaft groove provided in the guide groove.

[0009] Furthermore, the pressure head has a protrusion, and the inner wall of the rotating shaft groove has a limiting groove for avoiding the protrusion.

[0010] Furthermore, the pushing assembly has a pressing plate which is limitedly matched with the outer groove of the air box.

[0011] Furthermore, at least one outer skin top rod is provided on the mounting seat and is elastically floating and passes through the bracket to support the outer skin.

[0012] Furthermore, the pushing assembly, the air box limiting assembly and the foreskin assembly are arranged in sequence from top to bottom.

[0013] Furthermore, it also includes a edge pressing assembly, which includes a lifting block arranged between the air box limiting assembly and the pushing assembly, and the lifting block is provided with two vertically sliding edge pressing rods. When the lifting block descends, the edge pressing rods contact the corresponding side edges of the outer skin before the air box, and the air box limiting assembly is provided with a detachable corresponding elastic pressing assembly acting on the corresponding side faces of the edge pressing rods.

[0014] Furthermore, the elastic top pressure assembly includes a wedge block slidably arranged on the back plate of the air box limit assembly, and an elastic floating top pressure plate is provided on the side of the wedge block close to the edge pressure rod. When the lifting block is pressed down, a driving rod connected to the lifting block drives the wedge block to move so that the top pressure plate and the corresponding edge pressure rod are abutted against each other. When the lifting block rises, the driving rod is separated from the wedge block, and the wedge block is reset under the action of a reset spring to separate the top pressure plate from the corresponding edge pressure rod.

[0015] Furthermore, the wedge surface of the wedge block consists of a slope surface and a vertical plane.

[0016] It can be seen from the above technical scheme that the advantages of the present invention are: the air box and the flat outer skin are driven into the arc groove of the bracket by moving the pushing component, and the end of the outer skin is squeezed by the synchronously moving pressure head to complete the foreskin. The structure is simple, the foreskin is reliable, and the loading and unloading can be done manually or automatically with the cooperation of a robot; by setting the edge pressing component, the outer skin can be limited and pressed before the foreskin, so that the foreskin quality can be controlled.

[0017] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Refer to Figures 1 to 7 For further illustration of this application, asFigure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A wrapper device for a lighter as shown, comprising a base 1, a mounting seat 2 mounted on the base 1, a movable gas tank limiting component 3, a movable pressing component 4, and a wrapper component 5 disposed in the mounting seat 2. The mounting seat 2 has a receiving portion for placing an outer skin 6. The gas tank limiting component 3 includes a fixed shaft 31 for the gas tank to be sleeved. The wrapper component 5 includes two rotating shafts 51 and a bracket 52 disposed between the two rotating shafts 51. At least one elastic floating bracket ejector rod 54 is provided between the bracket 52 and the mounting seat 2. The bracket 52 has an arc groove 521 that fits the outer skin 6, and the rotating shaft 51 has a pressing head 512 for pressing the outer skin 6.

[0029] Specifically, the gas tank limiting component 3 further includes a limiting block 32 for limiting the gas tank sleeved on the fixed shaft 31. Two elastic floating bracket ejector rods 54 are provided between the bracket 52 and the mounting seat 2. Wherein, the outer end of the bracket ejector rod 54 is connected to the bracket 52, and the other end of the bracket ejector rod 54 is slidably inserted into the mounting seat 2, and a spring or other elastic member acting on the bracket ejector rod 54 is provided in the mounting seat 2. The gas tank limiting component 3 and the pressing component 4 can move in the horizontal direction, the vertical direction or the inclined direction, and can be adjusted according to the actual use conditions.

[0030] Preferably in this application, the pressing component 4, the gas tank limiting component 3 and the wrapper component 5 are arranged in sequence from top to bottom. When the pressing component 4 is pressed down, it drives the gas tank limiting component 3 to be pressed down into the wrapper component 5.

[0031] Specifically, the pressing component 4 is connected to a corresponding lifting drive mechanism. The gas tank limiting component 3 is connected to the base 1 through a guide rod, and an elastic support component is provided between the gas tank limiting component 3 and the base 1. When the pressing component 4 is pressed down, it can drive the gas tank limiting component 3 to be pressed down simultaneously. The elastic support component facilitates the rising and resetting of the gas tank limiting component 3.

[0032] In the embodiment of this application, both sides of the bracket 52 are respectively connected in cooperation with the driving card slots 511 of the corresponding rotating shafts 51 so that the rotating shafts 51 and the bracket 52 act synchronously.

[0033] Specifically, the driving card slot 511 has a C-shaped radial cross-section, and the opening of the driving card slot 511 faces the bracket 52. The corresponding side of the bracket 52 extends into the driving card slot 511. When the bracket 52 moves up and down, it will drive the two rotating shafts 51 to rotate towards or away from each other, so that the pressing head 512 can squeeze the corresponding end heads of the outer skin 6, making the two ends of the outer skin 6 fit reliably with the lighter.

[0034] The rotating shaft 51 can also be independently arranged with the bracket 52. The two rotating shafts 51 are synchronized through a transmission mechanism. After the bracket 52 moves down in place, the rotating shaft 51 rotates to make the pressing head 512 squeeze the corresponding end heads of the outer skin 6, and the function of covering the skin can also be realized.

[0035] In the embodiment of the present application, the pressing head 512 has an arc pressing surface. When the skin covering is completed, the center of the arc pressing surface coincides with the center of the arc groove 521. This makes the pressing area of the pressing head 512 large. Preferably, in the present application, the arc pressing surface and the arc groove 521 form a nearly continuous arc surface groove, with a large pressing area on the outer skin 6, making the contact between the outer skin 6 and the lighter flatter and tighter.

[0036] In the embodiment of the present application, the accommodating part for placing the outer skin 6 on the mounting seat 2 is a positioning groove 21. A guide groove 22 is provided at the bottom of the positioning groove 21. The bracket 52 is located in the guide groove 22, and the rotating shaft 51 cooperates with the corresponding rotating shaft groove 23 provided in the guide groove 22.

[0037] Specifically, the width of the guide groove 22 is basically the same as the outer diameter of the lighter after the skin covering is completed, so that the lighter can be positioned when it is pressed down. The rotating shaft groove 23 is located on the inner wall of the guide groove 22.

[0038] As Figure 6 shown, in the embodiment of the present application, the pressing head 512 has a convex part 5121, and a limiting groove 24 for avoiding the convex part 5121 is provided on the inner wall of the rotating shaft groove 23.

[0039] Specifically, one end of the limiting groove 24 extends to the opening of the rotating shaft groove 23. After the convex part 5121 abuts against the limiting groove 24, it can prevent the rotating shaft 51 from continuing to rotate, limit the reset position of the bracket 52, and avoid the separation of the bracket ejector rod 54 from the mounting seat 2 and the rotating shaft 51.

[0040] In an embodiment of the present application, the pressing component 4 has a pressing plate 41 that is in limiting cooperation with the outer groove of the air tank. When the pressing plate 41 presses down, it can act on the outside of the air tank. During the process of the pressing component 4 driving the air tank limiting component 3 to move downward, the lighter can be limited and clamped firmly, preventing the lighter from moving or falling off, and making the lighter wrapper reliable.

[0041] In an embodiment of the present application, at least one elastic floating outer skin ejector rod 53 that passes through the bracket 52 is provided on the mounting base 2 to support the outer skin 6. The outer skin 6 is lifted by the outer skin ejector rod 53 to prevent the outer skin 6 from being too thin to be laid flat easily.

[0042] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown in

[0043] Specifically, when using the hemming component 7, the lifting block 71 and the air box limiting component 3 are installed in sliding fit through the same guide shaft, and there is an elastic member between the lifting block 71 and the air box limiting component 3 with an elastic force less than that of the elastic support component. When the pressing component 4 descends, it acts on the lifting block 71 to drive the lifting block 71 to descend, and at the same time drives the hemming rod 72 to descend. After the hemming rod 72 descends to a certain position, the elastic pressing component 73 acts on the side of the hemming rod 72. When the pressing component 4 continues to descend, it drives the lifting block 71 and the air box limiting component 3 to descend simultaneously. After the hemming rod 72 contacts the outer skin 6, due to the reaction force of the mounting seat 2, the hemming rod 72 overcomes the resistance of the elastic pressing component 73 and generates relative sliding with the lifting block 71. The pressing component 4 is provided with avoidance holes 42 corresponding one-to-one to the hemming rods 72. The hemming rods 72 can enter the avoidance holes 42 to make the structure compact, and thus will not affect the continuous downward movement of the air box limiting component 3 to make the air box contact the outer skin 6. When the air box limiting component 3 continues to descend, it will pull the outer skin 6 to separate from the hemming rod 72 to make the outer skin 6 enter the guide groove 22. After the covering is completed, the lifting block 71 and the air box limiting component 3 rise and reset under the action of the corresponding elastic lifting members respectively. After the lifting block 71 resets to a certain height, the elastic pressing component 73 separates from the hemming rod 72, and the hemming rod 72 falls back under the action of gravity, which is convenient for the next covering. Using the hemming rod 72 can position the outer skin 6 before covering, and avoid the outer skin 6 moving during covering, resulting in misalignment of the outer skin 6 and affecting the appearance.

[0044] The elastic pressing component 73 includes a wedge block 731 slidably arranged on the back plate of the air box limiting component 3. An elastically floating pressing plate 733 is arranged on the side of the wedge block 731 close to the hemming rod 72. When the lifting block 71 is pressed down, the driving rod 735 connected to the lifting block 71 drives the wedge block 731 to move, so that the pressing plate 733 abuts against the corresponding hemming rod 72. When the lifting block 71 rises, the driving rod 735 separates from the wedge block 731, and the wedge block 731 resets under the action of the reset elastic member 732 to separate the pressing plate 733 from the corresponding hemming rod 72. By using the cooperation of the driving rod 735 and the wedge block 731, the control of the elastic pressing component 73 becomes simple and reliable, and the structure is simple.

[0045] Specifically, a connecting shaft connected to the top pressing plate 733 passes through the wedge block 731 and is connected to a nut. A buffer elastic member 734 is provided between the top pressing plate 733 and the wedge block 731 to prevent the top pressing plate 733 from rigidly contacting the flanging rod 72, and the thrust of the top pressing plate 733 acting on the flanging rod 72 can be adjusted by screwing the nut.

[0046] The wedge surface of the wedge block 731 is composed of a slope surface and a vertical plane. When the driving rod 735 acts on the vertical plane, the lifting block 71 continues to move downward without changing the pressing force of the elastic pressing assembly 73 acting on the flanging rod 72, which can prevent the pressure of the flanging rod 72 acting on the outer skin 6 from gradually increasing and affecting the pulling of the outer skin 6.

[0047] During operation, manually or using a manipulator, the heated lighter gas tank or shell is sleeved on the fixed shaft 31 of the gas tank limiting assembly 3 and initially positioned using the limiting block 32. Then, manually or using a manipulator, the outer skin 6 coated with hot melt adhesive is placed in the positioning groove 21 of the mounting seat 2. The lifting drive mechanism is controlled to drive the pressing assembly 4 downward. The pressing plate 41 is inserted into the outer slot of the gas tank or shell to perform reliable positioning and clamping fixation on the gas tank or shell. Then, the gas tank or shell is driven to descend into the positioning groove 21 and the outer skin 6 is driven to enter the guide groove 22 together. During the downward movement, the hot melt adhesive melts. Under the action of the guide groove 22 and the outer skin ejector rod 53, the outer skin 6 and the gas tank or shell are gradually bonded from the lower middle bottom to both sides. After the gas tank or shell contacts the arc groove 521 of the bracket 52 and continues to move downward, when the arc pressing surface of the pressing head 512 fits with the outer skin 6, the covering is completed. The pressing assembly 4 is lifted, the gas tank limiting assembly 3 automatically resets, and the bracket 52 and the outer skin ejector rod 53 respectively return to the initial state under the action of the corresponding elastic members and wait for the next covering operation. After the pressing assembly 4 and the gas tank limiting assembly 3 are reset in place, manually or using a manipulator, the gas tank or shell with the covering completed is removed, and the operation is completed.
