Description

Technical Field

[0001] The utility model relates to the technical field of ironing knives, in particular to an adjustable lock-type ironing knife. Background Technique

[0002] During the production of folded film bags, an ironing knife is needed for heat sealing. The temperature at the knife edge is increased through a heating mechanism, so that heat sealing can be performed when it presses on the film bag. For example, in the patent with the publication number "CN203637247U" and the patent name "An energy-saving ironing knife", waist-shaped mounting holes are opened on the bottom plate, and the bottom plate is detachably connected to the machine frame through the mounting holes; the support plate is formed by splicing two parallel vertical plates and a horizontal plate perpendicular to the vertical plates and located between the two vertical plates into a door shape, and the support plate is installed on one long end face of the bottom plate; there are two locking devices, which are respectively installed on the bottom plate on both sides of the support plate. Each locking device includes a copper pad and a pressing block detachably connected to the pad. The two groups of pads and pressing blocks respectively fix the two ends of the heating metal sheet. A T-shaped chute with a large belly and a small mouth is opened at the lower end of the copper pad. An I-shaped slide rail is fixed on the bottom plate at both ends of the support plate. The chute matches the slide rail and is slidably connected to the slide rail. The copper pad is also provided with a connection hole for connecting the positive and negative poles of the power supply and a locator for positioning the relative position of the locking device and the slide rail. However, the following problems still exist in the actual use of the above structure:

[0003] The length of the knife edge of the above ironing knife is fixed. When the length of the folded film bag is less than the length of the ironing knife, the entire ironing knife needs to be removed and a new ironing knife of a different size needs to be installed. The process of replacing the ironing knife is rather cumbersome, thus greatly reducing the production efficiency. At the same time, it also causes the ironing knife to fail to meet the usage requirements of different customers.

[0004] Therefore, we have proposed an adjustable lock-type ironing knife that can well solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an adjustable lock-type ironing knife to solve the problem in the above background technique that when the length of the folded film bag is less than the length of the ironing knife in the current market, the entire ironing knife needs to be removed and a new ironing knife of a different size needs to be installed. The process of replacing the ironing knife is rather cumbersome, thus greatly reducing the production efficiency. At the same time, it also causes the ironing knife to fail to meet the usage requirements of different customers.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an adjustable lock-type ironing knife, including an ironing knife main body and a heating tube hole opened inside the ironing knife main body for installing a heating tube;

[0007] It further includes: A heat-sealing wire is fitted into the upper end surface of the ironing knife body, and sliding grooves are formed on both sides of the ironing knife body. A locking mechanism is slidably arranged inside the sliding grooves, and the locking effect is achieved by the abutting head pressing the heat-sealing wire.

[0008] Preferably, the locking mechanism includes an abutting head and a sleeve. The abutting head is arranged in a semi-circular structure. The inner end of the abutting head contacts the heat-sealing wire, and the abutting head is fixed to the inner end of the sleeve.

[0009] Preferably, two sets of the abutting head and the sleeve are provided, and each set has two.

[0010] Preferably, the outer end of the sleeve extends into the upper end of the moving rod and is slidably connected to the moving rod. The outer end of the sleeve is threadedly connected to the inner end of the threaded rod. At the same time, a sliding connection structure is formed between the moving rod and the sliding groove.

[0011] Preferably, the threaded rod is arranged inside the upper end of the moving rod. The outer end of the threaded rod is rotationally connected to the moving rod through a bearing. A torsion spring is also sleeved on the outer side of the middle section of the threaded rod.

[0012] Preferably, a pull rope is wound around the outer end of the threaded rod, and the lower end of the pull rope is fixed to the lever.

[0013] Preferably, the lever is slidably arranged on the outer side of the moving rod. The lever is elastically slidably connected to the moving rod through a tension spring. The two ends of the tension spring are respectively fixed to the lever and the moving rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The adjustable locking ironing knife not only realizes the clamping and locking of the heat-sealing wire, so as to stably fix the heat-sealing wire in the ironing knife body, and thus there is no need to disassemble the entire ironing knife body for replacement, but only need to replace the heat-sealing wire. Moreover, it can be adjusted according to the length of the heat-sealing wire used, so that its applicability is relatively high, and it is flexible to use and has good applicability. And when the sleeve drives the abutting head to lock with the heat-sealing wire, a limiting effect can be achieved, so that the moving rod and the lever are not easily displaced. The specific content is as follows:

[0015] By limiting the sleeve, the sleeve can only slide left and right and cannot rotate. Thus, when the threaded rod rotates, it can drive the sleeve to slide inward, so that the inner end of the sleeve drives the abutting head to press the heat-sealing wire, thereby realizing the clamping and locking of the heat-sealing wire, so as to stably fix the heat-sealing wire in the ironing knife body, and thus there is no need to disassemble the entire ironing knife body for replacement, but only need to replace the heat-sealing wire.

[0016] Further, the tension spring drives the lever to move downward, so that while the lever moves downward, one end of the pulling rope is driven to move together, so that the pulling rope generates a pulling force and drives the threaded rod to rotate;

[0017] The lever is pushed back and forth, so that the lever drives the moving rod to slide in the chute, thereby adjusting the overall position of the moving rod, so that the buckle mechanism can be adjusted according to the length of the heat-sealing wire used, so that its applicability is relatively high, and it is flexible and has good applicability when used;

[0018] Furthermore, when the sleeve drives the contact head to lock with the heat-sealing wire, the limiting effect can be achieved, so that the moving rod and the lever are not easily displaced;

[0019] The torsion spring can drive the threaded rod to reverse through its elastic force, so that the threaded rod can not only wind up the pulling rope for convenient reuse, but also drive the sleeve threadedly connected to the other end to move outward, so that the sleeve drives the contact head to move away from the heat-sealing wire, thereby unlocking, and at this time, the heat-sealing wire can be taken out for replacement.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides the following technical solutions:

[0029] Embodiment 1: To solve the problem in the prior art that when the length of the folding film bag is less than the length of the hot knife, the entire hot knife needs to be removed and a new-sized hot knife needs to be installed, and the process of replacing the hot knife is relatively cumbersome, thus greatly reducing the production efficiency, and at the same time causing the hot knife to be unable to meet the usage requirements of different customers. Therefore, the following solution is disclosed, including a hot knife body 1 and a heating tube hole 2 opened inside the hot knife body 1 for installing a heating tube; further including: a heat-sealing line 3 is embedded in the upper end surface of the hot knife body 1, and sliding grooves 4 are opened on both sides of the hot knife body 1, and a locking mechanism is slidably arranged inside the sliding grooves 4, and the locking is achieved by the contact head 11 pressing the heat-sealing line 3. The locking mechanism includes a contact head 11 and a sleeve 10. The contact head 11 is arranged in a semi-circular structure, and the inner end of the contact head 11 contacts the heat-sealing line 3, and the contact head 11 is fixed to the inner end of the sleeve 10. There are two groups of contact heads 11 and sleeves 10, and each group has two.

[0030] First, a heat-sealing line 3 is embedded at the cutting edge of the hot knife body 1, and is heated by the heating tube in the heating tube hole 2, and the heat is transmitted to the heat-sealing line 3 through the hot knife body 1. One end of the heat-sealing line 3 contacts the folding film bag to achieve the heat-sealing effect. At the same time, when the length of the folding film bag is less than that of the hot knife body 1, the heat-sealing line 3 can be replaced separately at this time, and then it can be replaced with a heat-sealing line 3 of a suitable length. Subsequently, the lever 5 is loosened, and the lever 5 is driven to move downward by the tension spring 7, so that when the lever 5 moves downward, one end of the pull rope 8 is driven to move together, so that the pull rope 8 generates a pulling force and drives the threaded rod 9 to rotate. Through the limitation of the sleeve 10, the sleeve 10 can only slide left and right and cannot rotate. Therefore, when the threaded rod 9 rotates, it can drive the sleeve 10 to slide inward, so that the inner end of the sleeve 10 drives the contact head 11 to press the heat-sealing line 3, thereby realizing the clamping and locking of the heat-sealing line 3, and stabilizing the heat-sealing line 3 in the hot knife body 1. Therefore, it is not necessary to disassemble the entire hot knife body 1 for replacement, and only the heat-sealing line 3 needs to be replaced.

[0031] Embodiment 2: On the basis of Embodiment 1, a new technical solution is added to achieve the effect of limiting position, so that the moving rod 6 and the lever 5 are not easily displaced. Specifically, refer to Figures 2-4 , the outer end of the sleeve 10 extends into the upper end of the moving rod 6 and is slidably connected to the moving rod 6. Moreover, the outer end of the sleeve 10 is threadedly connected to the inner end of the threaded rod 9. At the same time, a sliding connection structure is formed between the moving rod 6 and the chute 4. The threaded rod 9 is arranged inside the upper end of the moving rod 6, and the outer end of the threaded rod 9 is pivotally connected to the moving rod 6 through a bearing. Moreover, a torsion spring 12 is sleeved on the outer side of the middle section of the threaded rod 9;

[0032] At the same time, the lever 5 can be pushed back and forth, so that the lever 5 drives the moving rod 6 to slide in the chute 4, thereby adjusting the overall position of the moving rod 6, so that the buckle mechanism can be adjusted according to the length of the heat-sealing wire 3 used, making its applicability higher, flexible to use and good in applicability. At the same time, when the sleeve 10 drives the contact head 11 to lock with the heat-sealing wire 3, the effect of limiting position can be achieved, so that the moving rod 6 and the lever 5 are not easily displaced.

[0033] Embodiment 3: On the basis of Embodiment 1, a new technical solution is added to facilitate unlocking. At this time, the heat-sealing wire 3 can be taken out for replacement. Specifically, refer to Figures 3-6 , a pull rope 8 is wound around the outer end of the threaded rod 9, and the lower end of the pull rope 8 is fixed to the lever 5. The lever 5 is slidably arranged outside the moving rod 6, and the lever 5 is elastically slidably connected to the moving rod 6 through a tension spring 7. Moreover, both ends of the tension spring 7 are fixed to the lever 5 and the moving rod 6 respectively.

[0034] When it is necessary to disassemble the heat-sealing wire 3, only need to push the lever 5 upward, so that the lever 5 drives one end of the pull rope 8 upward together, so that the pull rope 8 is relaxed, so that the pull rope 8 no longer exerts a pulling force on the threaded rod 9. At this time, the torsion spring 12 can drive the threaded rod 9 to reverse through the elastic force, so that the threaded rod 9 can not only wind up the pull rope 8 for reuse, but also drive the sleeve 10 threadedly connected to the other end to move outward, so that the sleeve 10 drives the contact head 11 away from the heat-sealing wire 3, thereby unlocking. At this time, the heat-sealing wire 3 can be taken out for replacement.

[0035] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0036] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
