Description

Technical Field

[0001] This utility model relates to the field of cigarette equipment, and more specifically, to a double push rod pin mechanism for a GDX2 packaging machine. Background Technology

[0002] The double-push-pack device includes a rear push rod. During the push stroke, it moves to the right to push two stacked packs of cigarettes. During the return stroke, the nylon push blocks overcome the resistance of the stacked packs and move backward, overcoming the tension spring force to lift upward and avoid the stacked packs. The rear push rod includes a push rod, a connecting pin, two tension springs, and two nylon push blocks. Each nylon push block is connected to a tension spring. When the push rod reaches its limit position, each nylon push block returns to its initial position under the force of the tension spring, preparing for the next push action, thus completing one push action cycle. In the prior art, the tension springs are prone to fatigue fracture or elastic failure during use. When the tension spring cannot return to its normal position, the push blocks are not completely ineffective and can still complete the push action under the action of inertia, which can easily lead to the quality risk of crushing the packs. In addition, during high-frequency, high-intensity reciprocating motion, the pin between the push rod and the push blocks often experiences problems such as severe wear of the push blocks and loosening of the pin. Utility Model Content

[0003] One objective of this invention is to provide a new technical solution for the double push rod pin mechanism of the GDX2 packaging machine, in order to solve the problems mentioned in the background art.

[0004] According to a first aspect of the present invention, a double push rod pin mechanism for a GDX2 packaging machine is provided, comprising a cigarette pusher block, a push rod, and a cigarette pack conveying channel.

[0005] The bottom of the push rod is rotatably connected to the smoke pusher block by a pin. The top of the smoke pusher block and the side of the push rod next to the smoke pusher block are both provided with pins, and the two pins are connected by a tension spring.

[0006] The pin has a set hole on its side wall, and the push rod has a fastening screw that is fixedly connected to the set hole. The smoke pusher can rotate around the pin.

[0007] The cigarette pack conveying channel is located beside the cigarette pusher block. The pusher rod can drive the cigarette pusher block to move and push the cigarette pack towards the cigarette pack conveying channel. When the pusher rod drives the cigarette pusher block to return, the subsequent cigarette pack causes the cigarette pusher block to rotate around the pin shaft. The cigarette pusher block can be reset under the action of the tension spring.

[0008] Optionally, according to the double push rod pin mechanism of the GDX2 packaging machine of this utility model, the bottom of the push rod is provided with a groove, the side wall of the groove matches the edge of the cigarette pusher, and when the cigarette pusher pushes the cigarette pack, the top of the cigarette pusher abuts against the side wall of the groove.

[0009] Optionally, according to the double push rod pin mechanism of the GDX2 packaging machine of this utility model, the bottom of the pusher block is a triangular plate structure, and the corners are rounded.

[0010] Optionally, according to the double push rod pin mechanism of the GDX2 packaging machine of this utility model, the screw of the pin is composed of a threaded section and a connecting section. The threaded section is threadedly connected to the pusher block and the push rod. The two ends of the tension spring are provided with connecting hooks, and the connecting hooks are hung on the connecting section.

[0011] Optionally, according to the GDX2 packaging machine double push rod pin mechanism of the present invention, the connecting section is provided with an annular groove, and the connecting hook of the tension spring is embedded in the annular groove.

[0012] Optionally, according to the double push rod pin mechanism of the GDX2 packaging machine of this utility model, the nut of the pin is provided with an internal hexagon countersunk hole for tightening or loosening the pin by rotating a wrench.

[0013] Optionally, according to the double push rod pin mechanism of the GDX2 packaging machine of this utility model, the pin is composed of a cylindrical head, a first smooth rod section and a second smooth rod section in sequence, the pusher block is rotatably connected to the first smooth rod section, the set hole is provided on the second smooth rod section, and the push rod is fixed to the second smooth rod section by a set screw.

[0014] Optionally, according to the GDX2 packaging machine double push rod pin mechanism of the present invention, the diameter of the first smooth rod segment is larger than the diameter of the second smooth rod segment, and the stepped surface between the first smooth rod segment and the second smooth rod segment is used to limit the position between the pin and the push rod.

[0015] This invention effectively prevents a series of quality problems caused by the lack of an effective locking mechanism for the pin, pin wear, and excessive wear between the pin and the pusher block during the high-speed, high-frequency reciprocating motion of the double pusher rod. These problems include pin loosening, severe wear of the pusher block, and wear of the pusher rod, which in turn cause wrinkles, scratches, and deformation of the cigarette pack. This reduces the product defect rate and greatly improves the effective operating rate of the equipment.

[0023] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0024] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] according to Figure 1 and Figure 2 As shown, this utility model provides a double push rod pin mechanism for a GDX2 packaging machine, including a cigarette pusher block 2, a push rod 3, and a cigarette pack conveying channel.

[0028] The bottom of the push rod 3 is rotatably connected to the smoke pusher block 2 via a pin 5. The top of the smoke pusher block 2 and the side of the push rod 3 located next to the smoke pusher block 2 are both provided with pins 6, and the two pins 6 are connected by a tension spring 4.

[0029] The cigarette pack conveying channel is located beside the cigarette pusher 2. The push rod 3 can drive the cigarette pusher 2 to move and push the cigarette pack assembly 1 towards the cigarette pack conveying channel. When the push rod 3 drives the cigarette pusher 2 to return, the subsequent cigarette pack assembly 1 causes the cigarette pusher 2 to rotate around the pin 5. The cigarette pusher 2 can be reset under the action of the tension spring 4.

[0030] The GDX2 model is a medium-speed packaging machine. During the folding and forming process of the small box transparent paper in the CH section, the cigarette pack group 1 wrapped with transparent paper is folded at the end of the forming wheel mold box and then lifted by the cigarette pack elevator at the forming wheel outlet to form a cigarette pack group 1 consisting of two packs of cigarettes. The cigarette pack group 1 is pushed into the end sealing channel for sealing by the reciprocating motion of the double push rod 3 assembly. When the double push rod 3 pushes the cigarette forward, the first working surface of the cigarette pusher 2 is in a vertically downward state, accurately and smoothly pushing the cigarette pack 1 into the sealing channel. After reaching the predetermined position, the double push rod 3 retracts. At this time, under the combined action of the resistance of the cigarette pack 1 and the pushing force of the push rod 3, the first working surface of the cigarette pusher 2 is in a horizontally upward state, and the second working surface contacts the cigarette pack 1. After retracting to the predetermined position, the tension of the tension spring 4 of the cigarette pusher 2 resets the cigarette pusher 2, preparing for the next cigarette pushing action. The double push rod 3 moves back and forth, pushing the cigarette pack 1 into the sealing channel in sequence to ensure the sealing quality of the transparent paper of the small box and improve the airtightness of the small box.

[0031] Furthermore, the bottom of the push rod 3 is provided with a groove, the side wall of which matches the edge of the pusher block 2. When the pusher block 2 pushes the cigarette pack assembly 1, the top of the pusher block 2 abuts against the side wall of the groove. In practice, the groove limits the position of the pusher block 2, ensuring that the pusher block 2 can effectively push the cigarette pack assembly 1.

[0032] Furthermore, the bottom of the pusher block 2 has a triangular plate structure, and the corners are rounded. In implementation, the side of the bottom of the pusher block 2 facing the tobacco pack conveying channel is the vertical No. 1 working surface, and the side away from the tobacco pack conveying channel is the inclined No. 2 working surface. The No. 1 working surface and the No. 2 working surface form a triangular structure. When the pusher block 2 returns, the No. 2 working surface contacts the subsequent tobacco pack group 1. The inclined surface causes the pusher block 2 to rotate around the pin 5. When it has fully returned, the pusher block 2 resets under the action of the tension spring 4.

[0033] Furthermore, the screw of pin 6 consists of a threaded section 61 and a connecting section 62. The threaded section 61 is threadedly connected to the smoke pusher 2 and the push rod 3. The two ends of the tension spring 4 are provided with connecting hooks, which are hooked onto the connecting section 62. The connecting section 62 is provided with an annular groove 63, and the connecting hook of the tension spring 4 is embedded in the annular groove 63. The tension spring 4 is fixed to the push rod 3 and the smoke pusher 2 respectively by pin 6. The tension spring 4 can rotate around the annular groove 63 of pin 6 without being affected by external forces, which greatly reduces the risk of bending and breaking of the tension spring 4 hook.

[0034] Optionally, in the GDX2 packaging machine double push rod 3 pin 6 mechanism of this utility model, the nut of the pin 6 is provided with an internal hexagon countersunk hole for tightening or loosening the pin 6 by turning with a wrench. The internal hexagon countersunk hole on the head of the pin 6 facilitates its disassembly and installation.

[0035] This invention effectively prevents the double push rod 3 from bending and deforming due to the fixed installation angle between the pin 6 and the tension spring 4 during high-speed, high-frequency reciprocating motion, and the tension spring 4 hook from bending and breaking. This prevents the pusher block 2 from continuing to work normally, resulting in quality problems such as wrinkling, scratching, and extrusion deformation of the cigarette pack assembly 1. At the same time, it reduces the difficulty of installing and disassembling the pin 6, reduces the product defect rate, and greatly improves the effective operating rate and maintenance efficiency of the equipment.

[0036] Then according to Figure 3 As shown, the pin 5 is composed of a cylindrical head, a first polished rod section 51, and a second polished rod section 52 in sequence. The smoke pusher 2 is rotatably connected to the first polished rod section 51, and the set hole 53 is provided on the second polished rod section 52. The push rod 3 is fixed to the second polished rod section 52 by a set screw. The diameter of the first polished rod section 51 is larger than the diameter of the second polished rod section 52, and the stepped surface between the first polished rod section 51 and the second polished rod section 52 is used to limit the position between the pin 5 and the push rod 3.

[0037] The cylindrical head serves as the outer retaining ring for the smoke pusher 2, limiting its movement and preventing it from loosening outwards while reducing friction and extending its service life. When the smoke pusher 2 is installed on the pin 5, the first smooth rod section 51 directly contacts and fits the smoke pusher 2, and the smoke pusher 2 moves circumferentially around the first smooth rod section 51. The second smooth rod section 52 is the fixing section of the entire pin 5. When the second smooth rod section 52 is installed on the push rod 3, it serves to fix the pin 5.

[0038] The locking hole 53 is on the second guide rod section 52. When the second guide rod section 52 is installed on the push rod 3, the locking screw of M4 cooperates with the locking hole 53 to lock and fix it, preventing the pin 5 from loosening outward.

[0039] This invention effectively prevents a series of quality problems such as loosening of the pin 5, severe wear of the pusher block 2, and wear of the pusher rod 3 during high-speed, high-frequency reciprocating motion of the double pusher rod 3. These problems are caused by the lack of an effective locking mechanism for the pin 5, wear of the pin 5, and significant wear between the pin 5 and the pusher block 2. As a result, the cigarette pack may become wrinkled, scratched, or deformed. This reduces the product defect rate and greatly improves the effective operating rate of the equipment.

[0040] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
