Description

Technical Field

[0001] The utility model relates to the technical field of water-based glue production, in particular to a sealing mechanism for filling water-based glue. Background Technique

[0002] As a kind of colloid with the characteristics of non-toxic and environmental protection, water-based glue is often used in the home decoration field for furniture bonding and also used as an adhesion agent for coatings. During production, usually a plastic bag is placed inside a packaging barrel, and it is sealed with the plastic bag, and then transported and protected by the external packaging barrel. Therefore, during production, after the material is poured into the plastic bag, a sealing mechanism is needed to seal it.

[0003] The traditional sealing part sets a non-heating part at the bottom and a lifting heating part at the top. After leveling the plastic film and fitting it on the non-heating part, the heating part is driven by a driving part to move downwards to heat-seal the plastic film. However, this operation method has certain drawbacks. Due to the internal pressure heating part below, the heating speed is slow and the upper and lower sides are not evenly heated. When using the method of not setting heating parts on both the upper and lower sides for heat-sealing, it is very easy to accidentally touch and cause the plastic film to be burned during the process of leveling the plastic film. Therefore, a sealing mechanism for filling water-based glue is specifically provided to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a sealing mechanism for filling water-based glue, which solves the problems that the traditional sealing part sets a non-heating part at the bottom, resulting in slow heating speed and uneven heating of the upper and lower sides, and when using the method of not setting heating parts on both the upper and lower sides for heat-sealing, it is very easy to accidentally touch and cause the plastic film to be burned during the process of leveling the plastic film.

[0005] To achieve the above purposes, the utility model is realized through the following technical solutions: A sealing mechanism for filling water-based glue includes a sealing clamping part and a self-lifting electrothermal mechanism arranged inside the sealing clamping part.

[0006] The electrothermal plate is vertically slidably arranged inside the sealing clamping part. The U-shaped connecting pipe is arranged at both ends of the electrothermal plate. The piston columns are respectively movably inserted into the two ends of the U-shaped connecting pipe. One group of piston columns is located below the electrothermal plate, and the return spring is movably sleeved on the outer surface of the other group of piston columns.

[0007] Preferably, the sealing clamping part includes a fixed clamping seat, a sliding clamping seat and a lifting hydraulic cylinder. The sliding clamping seat is arranged on the top of the fixed clamping seat. The lifting hydraulic cylinder is fixedly installed on both sides of the fixed clamping seat. The sliding clamping seat is fixedly installed with the output end of the lifting hydraulic cylinder.

[0008] Preferably, a support shaft is fixedly installed at the output end of the lifting hydraulic cylinder, connection blocks are fixedly connected to both sides of the sliding clamp seat, and the top end of the support shaft is fixedly connected to the connection blocks.

[0009] Preferably, slide rails are fixedly installed on both sides of the fixed clamp seat, anti - detachment grooves are formed at both ends of the sliding clamp seat, and the sliding clamp seat is slidably connected to the outer surface of the slide rails through the anti - detachment grooves.

[0010] Preferably, movable grooves are formed on the opposite sides of the fixed clamp seat and the sliding clamp seat, and the electric heating plate is vertically slidably arranged in the movable grooves.

[0013] The utility model discloses a sealing mechanism for filling water - based glue, and the beneficial effects thereof are as follows: By designing a self - lifting electric heating mechanism, when finishing the bag mouth of the packaging bag, the two electric heating plates contract inside the fixed clamp seat and the sliding clamp seat. At this time, the bag mouth of the packaging bag can be attached to the top of the fixed clamp seat, which is convenient for leveling and can also avoid thermal damage. During heat sealing, the lifting hydraulic cylinder is started, so that the sliding clamp seat moves downward. At this time, the upper and lower counter - thrust shafts are abutted against each other, so that the two groups of counter - thrust shafts move in opposite directions, thereby enabling a group of piston columns to move into the U - shaped communicating pipe. At this time, the pressure inside the U - shaped communicating pipe increases, so that the other group of piston columns drives the electric heating plate to move outwards, so that the two electric heating plates are attached to both sides of the plastic packaging bag for heat sealing, avoiding uneven heating during heat sealing and affecting the sealing effect.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] By providing a sealing mechanism for water-based glue filling in the embodiments of this application, the problem that the traditional sealing member has a slow heating speed and uneven heating on the upper and lower sides due to the setting of non-heating members at the bottom is solved. When using the method of setting heating members on both the upper and lower sides for heat sealing, it is very easy to accidentally touch and cause damage to the plastic film during the process of arranging the plastic film.

[0021] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation modes.

[0022] The embodiments of the present utility model disclose a sealing mechanism for water-based glue filling.

[0023] According to the attached Figures 1-3 As shown, it includes a sealing clamping member 1. The sealing clamping member 1 includes a fixed clamp seat 11, a sliding clamp seat 12, and a lifting hydraulic cylinder 14. The sliding clamp seat 12 is arranged on the top of the fixed clamp seat 11. The lifting hydraulic cylinder 14 is fixedly installed on both sides of the fixed clamp seat 11, and the sliding clamp seat 12 is fixedly installed with the output end of the lifting hydraulic cylinder 14.

[0024] The output end of the lifting hydraulic cylinder 14 is fixedly installed with a support shaft 16. Connecting blocks 15 are fixedly connected to both sides of the sliding clamp seat 12. The top end of the support shaft 16 is fixedly connected to the connecting block 15. Slide rails 13 are fixedly installed on both sides of the fixed clamp seat 11. Anti-detachment grooves 17 are opened at both ends of the sliding clamp seat 12. The sliding clamp seat 12 is slidably connected to the outer surface of the slide rail 13 through the anti-detachment grooves 17;

[0025] By starting the lifting hydraulic cylinder 14 and making its output end contract, the sliding clamp seat 12 is driven by the support shaft 16 to slide downward along the slide rail 13, so as to clamp and heat-seal the plastic bag through the fixed clamp seat 11 and the sliding clamp seat 12.

[0026] A self-lifting electrothermal mechanism 2 is arranged inside the sealing clamp 1. The self-lifting electrothermal mechanism 2 includes an electrothermal plate 22, a U-shaped communicating pipe 23, a piston column 27 and a return spring 25.

[0027] The electrothermal plate 22 is vertically slidably arranged inside the sealing clamp 1. The U-shaped communicating pipe 23 is arranged at both ends of the electrothermal plate 22. The piston columns 27 are respectively movably inserted into the two ends of the U-shaped communicating pipe 23. One group of piston columns 27 is located below the electrothermal plate 22. The return spring 25 is movably sleeved on the outer surface of the other group of piston columns 27. Activity grooves 18 are formed on the opposite sides of the fixed clamp seat 11 and the sliding clamp seat 12. The electrothermal plate 22 is vertically slidably arranged in the activity grooves 18.

[0028] When the sliding clamp seat 12 moves downward, the opposing shafts 24 on the upper and lower sides abut against each other, causing the two groups of opposing shafts 24 to move in opposite directions, so that one group of piston columns 27 moves into the U-shaped communicating pipe 23. At this time, the pressure inside the U-shaped communicating pipe 23 increases, causing the other group of piston columns 27 to drive the electrothermal plate 22 to move outward, so that the two electrothermal plates 22 are attached to both sides of the plastic packaging bag for heat-sealing, avoiding uneven heating during heat-sealing and affecting the sealing effect.

[0029] The bottom end of the electrothermal plate 22 is fixedly connected with a ceramic substrate 21. The ceramic substrate 21 is fixedly installed with one group of piston columns 27. The top of the other group of piston columns 27 is fixedly connected with an opposing shaft 24. The upper and lower groups of opposing shafts 24 are arranged opposite to each other. The ceramic substrate 21 is used to prevent the fixed clamp seat 11 and the sliding clamp seat 12 from getting hot due to heat transfer.

[0030] An inflation joint 26 is fixedly installed in the middle of the U-shaped communicating pipe 23. The inflation joint 26 penetrates through the fixed clamp seat 11 and the sliding clamp seat 12 respectively, facilitating the replenishment of gas when the air pressure inside the U-shaped communicating pipe 23 is insufficient.
