Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensers, in particular to a glue dispenser piston disassembly component. Background Art

[0002] In the production process of tobacco products, in order to transfer a small part of glue to the folded sheet of the tobacco package or the cigarette paper, a cigarette making machine with a gluing function is needed, such as the ZJ116 cigarette making machine. The current ZJ116 cigarette making machine includes a glue dispenser, which includes a plurality of output holes connected to the glue discharge port, and a piston is telescopically provided in each output hole. The piston moves to block the corresponding glue discharge port through the force of the input airflow, thereby achieving the effect of glue diversion.

[0003] After the existing equipment has been used for a long time, people often need to remove the piston from the output hole to inspect or maintain the glue dispenser. Among them, the glue dispenser removed from the equipment is full of glue accumulation around the piston, which easily increases the difficulty of disassembling the piston, and the existing method of disassembly is mostly knocking. However, since the piston is made of nylon material, if there is a force offset during the knocking process, it is easy to cause the piston to tilt and produce extrusion deformation or even wear, thereby affecting the subsequent effect of the piston blocking the output hole, and ultimately causing the equipment to leak glue and have a lot of glue accumulation at the glue outlet. Utility Model Content

[0004] In view of the above shortcomings, the utility model proposes a glue dispenser piston disassembly assembly, which is conducive to standardizing the direction of the force of the knocking rod hitting the piston through the coaxially arranged guide holes and grooves, thereby avoiding unnecessary skewness, extrusion and wear when the piston is disassembled, and ensuring the subsequent use of the piston.

[0026] See also Figures 1 to 3 A glue dispenser piston disassembly assembly includes: a mounting frame 100, the mounting frame 100 is used to abut against the end face of the glue dispenser, the mounting frame 100 is provided with a guide hole, the mounting frame 100 is provided with a knocking rod 110, the knocking rod 110 is movably penetrated through the guide hole, a groove 111 is provided at one end of the knocking rod 110 away from the guide hole, the axis of the groove 111 coincides with the axis of the guide hole, the groove 111 is used to be embedded with the piston 210 of the glue dispenser, the knocking rod 110 is provided with a limit block 120, an elastic member 130 is provided between the limit block 120 and the mounting frame 100, and the elastic member 130 is used to drive the knocking rod 110 to always press against the piston 210.

[0027] The glue dispenser piston disassembly assembly of the above structure, when in use, the elastic member 130 is in a compressed state, the groove 111 is aligned with one end of the piston 210 for cooperation, so that the knocking rod 110 is always pressed against the piston 210 under the elastic action of the elastic member 130, and then the mounting frame 100 is abutted against the end face of the glue dispenser, and finally the knocking rod 110 is knocked by a rubber hammer, so that the knocking rod 110 can push the piston 210 out of the output hole under the action of external force. Among them, since the end face of the existing piston 210 is an arc surface, the cooperation of the groove 111 and the piston is conducive to avoiding the slipping phenomenon when the knocking rod 110 applies force to the arc surface, and the axis of the guide hole and the groove 111 coincide, so that the knocking rod 110 and the piston 210 form a coaxial arrangement, which is conducive to standardizing the direction of the force of the knocking rod 110 knocking the piston 210, thereby avoiding unnecessary skew, extrusion and wear when the piston 210 is disassembled, and then ensuring the subsequent use of the piston 210.

[0028] See also Figure 3The existing glue dispenser includes a base 200, the output hole is a stepped hole, the base is provided with an air intake channel 201 connected to the large end of the stepped hole, the piston 210 is a T-shaped structure adapted to the shape of the stepped hole, and pressure plates 220 are provided at both ends of the step hole, one of the pressure plates 220 is provided with a through hole for connecting to the glue injection port, and a reset spring 230 is provided between the other pressure plate 220 and the piston 210. When the air intake channel 201 is inlet, the piston 210 extends out of the stepped hole to block the glue injection port; when the air intake channel 201 is disconnected from the air intake, the elastic member 130 drives the piston 210 to reset to open the glue injection port. When the glue dispenser is removed from the cigarette making machine, the two pressure plates 220 are first disassembled, and then the groove 111 is aligned with the small end of the piston 210, so that the piston 210 is driven to disengage from the stepped hole by subsequently knocking the knocking rod 110.

[0029] See also Figure 1 and Figure 2 Furthermore, the mounting frame 100 includes two L-shaped plates 101 arranged opposite to each other, a mounting plate 102 is connected between the two L-shaped plates 101, and a guide hole is provided on the mounting plate 102, which is conducive to simplifying the structure of the mounting frame 100 to reduce the processing difficulty of the mounting frame 100.

[0030] See also Figure 1 and Figure 2 Furthermore, the L-shaped plate 101 includes a horizontal plate and a vertical plate connected vertically, the horizontal plate is provided with a mounting groove, and a magnetic block 140 is built into the mounting groove, and the magnetic block 140 is used to be magnetically mounted on the end face of the glue dispenser. Specifically, since the existing glue dispenser is made of metal material, the magnetic block 140 and the end face of the glue dispenser are magnetically matched, which is conducive to quickly fixing the position of the mounting frame 100, thereby reducing the movement of the mounting frame 100 during the knocking process, and is also conducive to the subsequent rapid removal of the mounting frame 100, thereby improving people's use experience.

[0031] Furthermore, an inclined plate is connected between the vertical plate and the mounting plate 102 , which is conducive to the vertical plate, the mounting plate 102 and the inclined plate forming a triangular structure, thereby preventing the vertical plate from bending due to force and affecting the moving direction of the knocking rod 110 .

[0032] See also Figures 1 to 3 Furthermore, a plurality of guide holes are provided, and the plurality of guide holes are distributed on the mounting plate 102 along the same straight line, and a knocking rod 110 is provided corresponding to each guide hole. Specifically, since there are a plurality of existing pistons 210, each piston 210 corresponds to a glue injection port, and the plurality of pistons 210 are distributed in the same straight line, it is beneficial for different pistons 210 to block the corresponding glue injection ports to form a glue diversion. Among them, the knocking rod 110 and the corresponding piston 210 form a group of matching, which is beneficial to reduce the steps of installing the knocking rod 110 and facilitate people to disassemble the plurality of pistons 210 later.

[0033] See also Figures 1 to 3 Furthermore, one end of the multiple knocking rods 110 is commonly connected to the limiting plate 150, and the limiting plate 150 is arranged parallel to the mounting plate 102. When the limiting plate 150 is struck by an external force, the multiple knocking rods 110 move toward the side away from the guide hole, thereby forming an effect of simultaneously disassembling the multiple pistons 210 with a single knock, which is beneficial to speeding up the disassembly efficiency of the multiple pistons 210.

[0034] See also Figures 1 to 3 Furthermore, the limit block 120 is threadedly connected to the knocking rod 110, and the elastic member 130 is a spring sleeved on the outside of the knocking rod 110, one end of the spring is connected to the lower end surface of the mounting plate 102, and the other end of the spring abuts against the limit block 120, which is conducive to adjusting the position of the limit block 120 to keep the spring in a compressed state at all times. Among them, the elastic force of the spring is used to drive the knocking rod 110 to press against the piston 210, which is conducive to preventing the knocking rod 110 from being separated from the piston 210 and affecting the subsequent force on the piston 210 to cause deviation. It can be understood that the elastic member 130 can be made of a material with elastic deformation ability such as rubber or silicone as needed, and the details are not described in detail.

[0035] Furthermore, the knocking rod 110 includes an external threaded section and a smooth section, the limit block 120 is provided with an internal threaded hole, the internal threaded hole is threadedly matched with the external threaded section, and the groove 111 is provided at the end of the smooth section, so that the piston 210 is pushed by the end of the smooth section, thereby reducing the presence of edges on the surface of the knocking rod 110 and affecting the subsequent movement of the piston 210.

[0036] Furthermore, the mounting frame 100 is made of stainless steel, thereby ensuring that the mounting frame 100 has good structural strength, and the striking rod 110 is made of nylon, which is beneficial to improving the structural strength of the striking rod 110 and extending the service life of the striking rod 110.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
