Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette machinery and equipment maintenance, and particularly relates to a glue gun cleaning device for a forming machine. Background Art

[0002] Filter rod forming technology mainly involves the use of filter rod forming machines, which generally consist of two parts: pre-treatment and rolling.

[0003] The main task of the pre-treatment section is to process the filter material into a shape suitable for rolling. This process will vary depending on the filter material used. For example, for cellulose acetate material, the operations of opening the filament bundle and applying plasticizer are required. For paper material, the pre-treatment section mainly completes the folding and cutting of the paper core. The rolling section is to wrap the initially formed filter material into strips and cut it into sticks. The structure of this part is basically the same as the rolling part of the cigarette making machine, but because the filter material has a large rebound force, it needs to be able to bond quickly and firmly at the joint. To achieve this, high-speed filter rod forming machines usually use hot melt glue as the adhesive, and use cooling method after gluing the joint to accelerate bonding.

[0004] In the current filter rod forming technology in the cigarette industry, the gluing system of the forming machine adopts a spiral glue spraying process, which combines the uniform circular motion of the glue spraying with the uniform linear motion of the forming paper supply. The glue line on the forming paper is a spiral line, which can greatly reduce the width of the glue line and reduce the penetration of the center line glue through the forming paper during gluing. It is suitable for high-speed production of filter rod equipment.

[0005] In the actual production process, since the spiral spray glue gun chamber cannot be disassembled separately, the maintenance of the chamber generally adopts the method of disassembling the glue gun as a whole and soaking it in hot water. The workload is large and the time is long, and the rubber on the inner wall of the chamber cannot be completely cleaned, resulting in poor maintenance effect. At the same time, the installation of the spiral spray glue gun requires precise positioning. Frequent disassembly and installation will cause the positioning position of the spiral spray glue gun to shift, affecting the production efficiency of the filter rod equipment.

[0028] To more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following describes specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the drawings described below are merely examples of the present invention. A person skilled in the art can, without inventive effort, derive other drawings and other embodiments from these drawings. Furthermore, design orientations only represent relative positional relationships between components, not absolute positional relationships.

[0029] The present invention provides a cleaning device for a molding machine glue gun. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , mainly including a glue gun 5, a feeding component 1, and a recovery component 2.

[0030] See Figure 1-Figure 5 The embodiment of the present application provides a glue gun cleaning device for a molding machine. The glue gun is fixed on the molding machine, the feeding component 1 is arranged at the upstream position of the glue gun, and the recovery component 2 is arranged at the downstream position of the glue gun. The feeding component 1 and the recovery component 2 can be connected to different joints on the glue gun. A solvent tank 11 is provided inside the feeding component 1. The solvent tank 11 stores a cleaning solvent. The cleaning solvent can clean the glue gun. When cleaning the glue gun, the feeding component 1 will guide the cleaning solvent in the solvent tank 11 into the glue gun. After passing through the glue gun, the cleaning solvent falls onto the recovery component 2. During the process of the cleaning solvent passing through the glue gun, the glue gun is cleaned. The glue gun does not need to be disassembled during the entire cleaning process, which avoids inaccurate positioning of the glue gun due to frequent disassembly and installation. The maintenance time of the glue gun is reduced by reducing the steps of disassembling the glue gun, thereby improving equipment efficiency.

[0031] In one embodiment, the feed assembly 1 includes a first housing 12, the bottom of which is connected to the side of the first housing 12 to form a solvent tank 11. A plurality of isolation panels 13 are also disposed within the first housing 12, integrally connected to the surface of the first housing 12. The isolation panels 13 separate the solvent tank 11 into a plurality of solvent units 111, each of which stores a solvent for cleaning the glue gun. The feed assembly 1 also includes a regulating valve 3, which can direct the solvent in a single solvent unit 111 to the glue gun. The regulating valve 3 can be used to direct different solvents into the glue gun in a predetermined order, thereby achieving a better cleaning effect.

[0032] Furthermore, the regulating valve 3 is provided with multiple liquid inlet holes 31 and liquid outlet holes 32. The feeding assembly 1 also includes multiple water inlet pipes and water outlet pipes. One end of each of the multiple water inlet pipes is disposed within the multiple solvent units 111. One end of each of the multiple water inlet pipes contacts the solvent within the multiple solvent units 111, and the other end of each of the multiple water inlet pipes can be inserted into the multiple liquid inlet holes 31. One end of the water outlet pipe can be inserted into the cleaning connector on the glue gun, and the other end can be inserted into the liquid outlet hole 32. Both ends of the water inlet pipe and the water outlet pipe can be threaded to strengthen the connection between the two ends.

[0033] In order to ensure the conduction rate of the solvent in the solvent unit 111, a water pump and a lithium battery are also provided in the solvent unit 111. The water pump inlet is placed in the solvent unit 111, and the lithium battery is connected to the water pump motor to provide the power required for the operation of the water pump.

[0034] Specifically, the regulating valve 3 includes a regulating shell 33 and a regulating part 34 arranged inside the regulating shell 33. Multiple liquid inlet holes 31 and liquid outlet holes 32 are arranged on the surface of the regulating shell 33, and the liquid inlet holes 31 and the liquid outlet holes 32 are respectively arranged at both ends of the regulating shell 33. The regulating part 34 can rotate in the regulating shell 33. During the rotation process, the regulating part 34 is always connected to a single liquid inlet hole 31 and a liquid outlet hole 32. The solvent flows from the water inlet pipe to the inside of the regulating valve 3, reacts with the rubber inside the glue gun, and flushes the glue scale inside the glue gun, thereby cleaning the glue gun.

[0035] The regulating portion 34 includes a first regulating block 341, which is disposed at one end of the regulating housing 33. The first regulating block 341 is embedded within the regulating housing 33 and is located at the end where the liquid inlet 31 is located. The first regulating block 341 is arc-shaped, and the arc spacing between the two endpoints of the first regulating block 341 is the distance occupied by the liquid inlet 31 on the regulating housing 33. During rotation within the regulating housing 33, the first regulating block 341 always connects to only one liquid inlet 31 and blocks the remaining liquid inlet 31. The regulating portion 34 also includes a second regulating block 342, which is disposed at the other end of the regulating housing 33. The second regulating block 342 is embedded within the regulating housing 33 and is located at the end where the liquid outlet 32 ​​is located. The second regulating block 342 is arc-shaped, and preferably, the second regulating block 342 can be configured as a semicircle. When the glue gun needs to be cleaned, the second regulating block 342 rotates and connects to the liquid outlet 32 ​​to direct the cleaning solution into the glue gun. When the glue gun does not need to be cleaned, the second regulating block 342 rotates and blocks the liquid outlet 32, isolating the cleaning solution. To prevent the first regulating block 341 and the second regulating block 342 from interfering with each other during rotation, the first regulating block 341 and the second regulating block 342 are independently embedded on either side of the regulating housing 33, and the first regulating block 341 is not connected to the second regulating block 342.

[0036] The adjustment unit 34 also includes a first handle having one end integrally connected to the first adjustment block 341, and a second handle having one end integrally connected to the second adjustment block 342. The other ends of the first and second handles are disposed outside the adjustment housing 33. The operator can rotate the first handle to drive the first adjustment block 341 to select the type of solvent in the solvent chamber 11. The operator can also rotate the second handle to drive the second adjustment block 342 to direct the solvent into the glue gun for cleaning.

[0037] In order to facilitate the diversion of the solvent in the solvent unit 111, a diversion pipe 35 is further provided inside the regulating shell 33. The two ends of the diversion pipe 35 are respectively connected to the liquid inlet hole 31 and the liquid outlet hole 32. The water inlet pipe guides the solvent in the solvent unit 111 from the liquid inlet hole 31 to the inside of the diversion pipe 35. After the solvent flows through the liquid outlet hole 32 in the diversion pipe 35, it enters the water outlet pipe. The solvent is guided to the inside of the glue gun in the water outlet pipe. The solvent contacts the impurities inside the glue gun to clean the glue gun.

[0038] It is foreseeable that if the spacing between the liquid inlet holes 31 is too small, two adjacent liquid inlet holes 31 may be simultaneously conductive during the rotation of the first adjustment block 341, causing the solvents in the two solvent units 111 to mix and flow into the glue gun, thereby reducing the cleaning effect of the glue gun. To ensure the cleaning effect of the glue gun, the multiple liquid inlet holes 31 are evenly spaced on the surface of the adjustment housing 33, and the spacing between two adjacent liquid inlet holes 31 is greater than the aperture of the liquid inlet hole 31.

[0039] In one embodiment, the recovery component 2 includes a second box body 21 and a second pipe 22. One end of the second pipe 22 can be placed inside the second box body 21, and the other end can be plugged into the cleaning connector on the glue gun. It should be noted that the second pipe 22 and the water outlet pipe are respectively connected to different cleaning connectors of the glue gun.

[0040] Preferably, movable casters 4 are provided at the bottom of the first box body 12 and the bottom of the second box body 21 to facilitate the movement of the feeding assembly 1 and the recovery assembly 2. The glue gun can be maintained on the machine without disassembling the glue gun, avoiding frequent installation and alignment of the glue gun and ensuring the positioning accuracy of the glue gun.

[0041] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations.
