Description

Technical Field

[0001] This utility model belongs to the field of assembly machine technology, specifically relating to a double-stroke high-speed hook knife module for assembly machines. Background Technology

[0002] Assembly machines are used to assemble products, such as gift box assemblers, book box assemblers, wine box assemblers, and cigarette box assemblers. These machines use positioning units to position the products. For larger packaging boxes, they can be directly conveyed and assembled. However, for smaller packaging boxes, additional mechanisms are needed to ensure proper feeding. Therefore, hook-shaped modules are installed inside the assembly machine to hook and convey smaller boxes. However, this method results in a complex internal structure, occupies a large space, and thus affects production capacity. Furthermore, secondary handling affects product accuracy, and there are other issues... Some assembly machines require extended hook knife modules due to excessively long feeding distances. While the hook knife distance can be addressed, the length limitation prevents high-speed feeding, impacting overall machine productivity. Furthermore, it necessitates more space for the extended hook knife module installation. Controlling the feeding length by shortening the hook knife module requires adjusting the edge forming mechanism to accommodate situations where the hook knife module's stroke is insufficient, leading to longer product model changes, a more complex and bulky structure, and inconvenient maintenance. Therefore, we propose a hook knife module with a folding function that doubles the stroke. Utility Model Content

A first synchronous pulley and a second synchronous pulley are respectively installed in the first and second mounting bases. A synchronous belt is installed between the first and second synchronous pulleys. The servo geared motor is fixedly connected to a motor bracket, which is fixedly mounted on one side of the translation beam. The servo geared motor and the first synchronous pulley are located at the same end of the translation beam. A coupling is provided inside the motor bracket. The output shaft of the servo geared motor is connected to one end of the coupling. The rotation shaft of the first synchronous pulley passes through the first mounting base and connects to the other end of the translation beam and the coupling. A first clamping member is installed on the top of the bottom beam, and a second clamping member is installed on one side of the sliding member. The first clamping member clamps and fixes the bottom of the synchronous belt, and the second clamping member clamps and fixes the top of the synchronous belt.

[0007] As a preferred technical solution of this utility model, the sliding member includes a second slider, the second slider is slidably mounted on the surface of the second guide rail, a connecting block is mounted on the top of the second slider, the lifting cylinder is mounted on the top of the connecting block, and the second clamping member is fixedly mounted on the side of the connecting block.

The lower and upper parts of the synchronous belt are respectively connected to the first clamping member and the second clamping member, while the bottom beam is fixed. Therefore, when the synchronous belt is driven, the translation mechanism moves forward along the first guide rail under the action of the first guide rail and the first slider. During this process, the sliding member drives the lifting cylinder to move forward along the second guide rail. Thus, under the action of the translation mechanism and the sliding member, the hook knife assembly has double the stroke. Therefore, the product can be hooked and transported at high speed over long distance without the need for secondary handling of the product, which effectively improves the product production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-8 The present invention provides the following technical solution: a double-stroke high-speed hook knife module for an assembly machine, including a bottom beam 1 installed in the assembly machine, a first guide rail 2 installed at the top of the bottom beam 1, a translation mechanism 3 slidably installed on the surface of the first guide rail 2, a drive mechanism 4 installed on one side of the translation mechanism 3, a sliding member 5 slidably installed on the top of the translation mechanism 3, a lifting cylinder 6 installed on the top of the sliding member 5, the telescopic end of the lifting cylinder 6 being connected to the hook knife assembly 7, and the drive mechanism 4 being able to drive the translation mechanism 3 and the sliding member 5 to move forward.

[0023] In this embodiment, the translation mechanism 3 includes a translation beam 31, a connecting plate 32 is installed at the bottom end of the translation beam 31, a first slider 33 is installed at the top end of the connecting plate 32, the first slider 33 is slidably installed on the surface of the first guide rail 2, and a second guide rail 34 is installed at the top end of the translation beam 31.

[0024] Specifically, since the first slider 33 is slidably connected to the first guide rail 2, the translation beam 31 can slide along the direction of the first guide rail 2.

[0025] In this embodiment, the drive mechanism 4 includes a servo geared motor 41, a first mounting base 42, and a second mounting base 43. The first mounting base 42 and the second mounting base 43 are respectively mounted on the same side at both ends of the translation beam 31. A first synchronous pulley 44 and a second synchronous pulley 45 are respectively installed in the first mounting base 42 and the second mounting base 43. A synchronous belt 46 is installed between the first synchronous pulley 44 and the second synchronous pulley 45. The servo geared motor 41 is fixedly connected to a motor bracket 47, and the motor bracket 47 is fixedly mounted on one side of the translation beam 31. The servo geared motor 41 and the first synchronous pulley 44 are located at the same end of the translation beam 31. A coupling 48 is provided inside the motor bracket 47. The output shaft of the servo geared motor 41 is connected to one end of the coupling 48. The rotating shaft of the first synchronous pulley 44 passes through the first mounting base 42 and is connected to the other end of the translation beam 31 and the coupling 48. A first clamping member 8 is installed on the top of the bottom beam 1. A second clamping member 9 is installed on one side of the sliding member 5. The first clamping member 8 is clamped and fixed to the bottom of the synchronous belt 46, and the second clamping member 9 is clamped and fixed to the top of the synchronous belt 46.

[0026] Specifically, the first synchronous pulley 44 is driven to rotate by the servo reduction motor 41, and thus the second synchronous pulley 45 rotates under the action of the synchronous belt 46. The first clamping member 8 and the second clamping member 9 are clamped and fixed to the synchronous belt 46, so the synchronous belt 46 will drive the first clamping member 8 and the second clamping member 9 to move. The first clamping member 8 is fixedly installed on the surface of the bottom beam 1, so the translation beam 31 slides forward along the direction of the first guide rail 2 under the action of the first clamping member 8. The second clamping member 9 is fixed to the sliding member 5, and the sliding member 5 is slidably installed on the top of the translation mechanism 3. So the second clamping member 9 will drive the sliding member 5 to slide forward along the top of the translation mechanism 3. In this way, the hook knife assembly 7 can move forward twice, so that the hook knife assembly 7 has double the stroke.

[0027] In this embodiment, the sliding member 5 includes a second slider 51, which is slidably mounted on the surface of the second guide rail 34. A connecting block 52 is mounted on the top of the second slider 51, a lifting cylinder 6 is mounted on the top of the connecting block 52, and a second clamping member 9 is fixedly mounted on the side of the connecting block 52.

[0028] Specifically, since the second slider 51 is slidably mounted on the surface of the second guide rail 34, the second clamping member 9 will drive the connecting block 52 to move laterally. In turn, under the action of the second slider 51, the lifting cylinder 6 slides forward along the direction of the second guide rail 34. Under the action of the first slider 33 in conjunction with the first guide rail 2 and the second slider 51 in conjunction with the second guide rail 34, the hook knife assembly 7 can move at high speed to a suitable position to hook and deliver the product.

[0029] In this embodiment, a slotted photoelectric switch 10 is installed at one top end of the bottom beam 1, and a sensing plate 11 is installed on the side of the first mounting base 42. When the slotted photoelectric switch 10 senses the sensing plate 11, the first clamping member 8 is located on the side of the second synchronous pulley 45 and the second clamping member 9 is located on the side of the first synchronous pulley 44. At this time, the hook knife module is in the initial position.

[0030] Specifically, the synchronous belt 46 drives the translation mechanism 3 to slide along the direction of the first guide rail 2. When the servo reduction motor 41 rotates in the opposite direction, the synchronous belt 46 drives the translation mechanism 3 and the sliding member 5 to slide back. When the slotted photoelectric switch 10 detects the sensing plate 11, the servo reduction motor 41 stops working. At this time, the hook knife assembly 7 returns to its original position, which is convenient for the next product hooking and feeding.

[0031] In this embodiment, a first cable chain frame 12 is fixedly installed on one side of the bottom beam 1, and a second cable chain frame 13 is also installed inside the assembly machine. A lower cable chain 14 and an upper cable chain 15 are respectively provided inside the first cable chain frame 12 and the second cable chain frame 13. A first fixing member 16 is fixedly connected to one side of the translation beam 31, and a second fixing member 17 is installed on the top of the connecting block 52. The first fixing member 16 is fixed to one end of the lower cable chain 14, and the second fixing member 17 is fixed to one end of the upper cable chain 15.

[0032] Working principle: The servo reducer motor 41 drives the synchronous belt 46 for transmission. The first clamping member 8 and the second clamping member 9 are both clamped and fixed to the synchronous belt 46. Therefore, the linkage of the single synchronous belt 46 causes the translation beam 31 to drive the first slider 33 to slide forward along the first guide rail 2. The connecting block 52 drives the second slider 51 to slide forward along the second guide rail 34. As a result, when the translation mechanism 3 moves forward, the hook knife assembly 7 also moves forward, and the distance is twice the forward movement of the translation mechanism 3. The first synchronous pulley 44 and the second synchronous pulley 45, together with the synchronous belt 46, can accurately control the forward movement. Moreover, under the action of the first slider 33, the first guide rail 2, and the second slider 51, together with the second guide rail 34, the hook knife assembly 7 can move at high speed to the appropriate position to hook and deliver the product. The lifting cylinder 6 can drive the hook knife assembly 7 to lift and lower to hook and deliver the product, thus enabling the hook knife assembly 7 to achieve high precision, high speed, and long-distance transmission.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
