Description

Technical Field

[0001] This utility model belongs to the field of cement packaging bag processing technology, and in particular relates to an automatic bonding device for moisture-proof inner lining of cement packaging bags. Background Technology

[0002] In the production of cement packaging bags, a plastic film liner is usually attached to the inner wall of the bag to enhance its moisture-proof performance. Currently, this process relies heavily on manual operation, where the liner is manually placed into the glued packaging bag and pressed to adhere. This method is inefficient, labor-intensive, and makes it difficult to ensure the uniformity and consistency of the glue application, easily leading to wrinkles, poor adhesion, or localized missed areas. Manual operation also makes it impossible to precisely control the amount of glue applied and the bonding pressure, resulting in adhesive waste and affecting the sealing and moisture-proof effect of the liner. This low level of automation has become a significant factor restricting the improvement of packaging bag quality and large-scale production.

[0003] To address these issues, we provide an automatic sealing device for the moisture-proof lining of cement packaging bags. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic bonding device for the moisture-proof lining of cement packaging bags. The device involves fixing a bag-feeding shaft motor below a base platform, fixing a bag-feeding rotating shaft to the output end of the motor, and setting a roller frame on one side of the base platform. Two glue rollers are vertically arranged inside the roller frame. The cement packaging bag is placed upside down on a bag-feeding plate fixed to the side wall of the bag-feeding rotating shaft. The bag-feeding shaft motor drives the rotating shaft to rotate, causing the cement packaging bag on the bag-feeding plate to pass through the roller frame. The two glue rollers inside the roller frame apply glue to both sides of the inner surface of the cement packaging bag, facilitating the adhesion of the moisture-proof lining. The lining assembly is set on the end of the base platform away from the bag-feeding rotating shaft. When the cement packaging bag, after glue application, turns to one side of the lining assembly, the lining assembly places the moisture-proof lining on the outside of the cement packaging bag, completing the automatic bonding of the moisture-proof lining.

Detailed Implementation

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1 to 3 This utility model relates to an automatic sealing device for moisture-proof lining of cement packaging bags, comprising a bag-covering assembly 1, a lining assembly 2, and a base frame 3. The bag-covering assembly 1 includes a bag-covering rotating shaft 101, a bag-covering shaft motor 102, two sets of glue rollers 103, and a roller frame 104. The bag-covering shaft motor 102 is fixedly mounted below the base frame 3, and the bag-covering rotating shaft 101 is fixedly mounted on the output end of the bag-covering shaft motor 102. The roller frame 104 is set on one side of the base frame 3, and two glue rollers 103 are vertically arranged inside the roller frame 104. The cement packaging bag is then wrapped around the bag-covering rotating shaft 101. On the bagging plate 101a fixed to the side wall, the bagging shaft motor 102 drives the bagging shaft 101 to rotate, so that the cement packaging bag on the bagging plate 101a passes through the roller frame 104, and the two glue rollers 103 inside the roller frame 104 apply glue to the two inner sides of the cement packaging bag, thereby facilitating the adhesion of the moisture-proof liner; by setting the liner assembly 2 on the end of the base frame 3 away from the bagging shaft 101, when the cement packaging bag that has completed the glue application turns to the side of the liner assembly 2, the liner assembly 2 puts the moisture-proof liner on the outside of the cement packaging bag, completing the automatic adhesion of the moisture-proof liner.

[0024] Specifically, the base frame 3 is a long table-shaped structure. The bagging shaft motor 102 is set on the lower end of one end of the base frame 3. The output end of the bagging shaft motor 102 passes through the table surface of the base frame 3. The bagging shaft 101 is fixedly sleeved on the output end of the bagging shaft motor 102. A set of bagging plates 101a are fixedly arranged in a circumferential array on the outer side wall of the bagging shaft 101. The bagging plates 101a are horizontally arranged. The roller frame 104 is set on one side of the base frame 3. Two glue rollers 103 are set inside the roller frame 104. The two glue rollers 103 are respectively attached to the upper and lower sides of the bagging plate 101a. The roller axis of the glue roller 103 points to the axis of the bagging shaft 101. The liner assembly 2 is set on the end of the base frame 3 away from the bagging assembly 1.

[0025] Furthermore, the roller frame 104 is a U-shaped structure with its opening facing the axis of the bag-covering shaft 101. Vertical slide plates 104a are fixedly installed on the inner side of the upper and lower horizontal plates of the roller frame 104 near the bottom frame 3. Roller slide seats 103a are slidably connected between the upper and lower vertical slide plates 104a and the vertical bottom plate of the roller frame 104, respectively. Two glue rollers 103 are rotatably installed in the two roller slide seats 103a.

[0026] Furthermore, a set of top seat springs 103a-1 are fixedly connected to the side of the roller slide 103a away from the glue roller 103. The end of the top seat spring 103a-1 away from the roller slide 103a is fixedly connected to the inner side of the horizontal plate of the roller frame 104. The top seat spring 103a-1 pushes the roller slide 103a, so that the glue roller 103 adheres to the surface of the bag plate.

[0027] Furthermore, glue injection pipes 103b are respectively provided on the outer sides of the upper and lower end horizontal plates of the roller frame 104. A set of glue injection branch pipes 103b-1 are connected to the side of the glue injection pipes 103b near the roller frame 104. The glue injection branch pipes 103b-1 at both ends pass through the horizontal plates on both sides of the roller frame 104 and the two roller slides 103a respectively. Glue enters into each glue injection branch pipe 103b-1 through the glue injection pipes 103b and is applied to the outer side of the glue roller 103.

[0028] The operation process in this embodiment is as follows: The cement packaging bag is reversed and placed on the bagging plate 101a. The bagging shaft motor 102 drives the bagging shaft 101 to rotate, so that the bagging plate 101a with the cement packaging bag reversed is rotated to the inside of the roller frame 104. The top seat spring 103a-1 pushes the roller slide 103a, so that the glue roller 103 is attached to the surface of the bagging plate, thereby applying the glue on the glue roller 103 to the surface of the cement packaging bag. Example

[0029] Please see Figures 1 to 5Based on Embodiment 1, the liner assembly 2 includes a liner rotating shaft 201, a liner shaft motor 202, and a set of liner pushers 203. By fixing a set of liner plates 201a in a circumferential array on the outer side wall of the liner rotating shaft 201, the moisture-proof liner is linerbed on the outside of the liner plates 201a. The liner shaft motor 202 drives the liner rotating shaft 201 to rotate, so that the liner plate 201a with the moisture-proof liner faces the bag plate 101a with the cement packaging bag inside out. The liner pushers 203 push the moisture-proof liner on the liner plate 201a toward the bag plate 101a, so that the moisture-proof liner is linerbed on the outside of the inside out cement packaging bag, thus completing the bonding of the moisture-proof liner.

[0030] Specifically, the bushing shaft motor 202 is located at the lower end of the base frame 3 away from the end of the bagging assembly 1. The output end of the bushing shaft motor 202 passes through the base frame 3. The bushing shaft 201 is fixedly sleeved on the output end of the bushing shaft motor 202. A set of bushing plates 201a are fixedly arranged in a circumferential array on the outer side wall of the bushing shaft 201. The plates of the bushing plates 201a are arranged in parallel. A set of push-blade grooves 201a-1 are opened through the plates of the bushing plates 201a. The push-blade plates 203 are U-shaped structures with their openings facing away from the axis of the bushing shaft 201. Each push-blade plate 203 is slidably sleeved in the push-blade grooves 201a-1 on each bushing plate 201a.

[0031] Furthermore, a vertical push plate 203a is fixedly mounted on the lower side of the push plate 203 near the bushing shaft 201. A push cylinder 204 is installed at the lower end of the base frame 3. The telescopic end of the push cylinder 204 faces the bushing shaft motor 202. A push plate sleeve 204a is fixedly installed on the output end of the push cylinder 204. The push plate sleeve 204a has an upward-opening U-shaped structure. The vertical push plate 203a is sleeved inside the push plate sleeve 204a. When the bushing shaft motor 202 drives the bushing shaft... When 201 rotates, so that the liner plate 201a with the moisture-proof inner lining faces the bag plate 101a with the cement packaging bag inside, the vertical push plate 203a below the push plate 203 inside the liner plate 201a is put into the push plate sleeve 204a. The push cylinder 204 pulls the push plate sleeve 204a to move, so that the push plate 203 moves towards the bag assembly 1, thereby pushing the moisture-proof inner lining on the outside of the liner plate 201a to the outside of the bag plate 101a with the cement packaging bag inside.

[0032] Furthermore, a pusher roller seat 203b is fixedly installed on one end of the upper and lower horizontal plates near the opening end of the pusher plate 203. A pusher roller 203b-1 is rotatably installed on the side of the pusher roller seat 203b facing away from the sleeve shaft 201. The roller axis of the pusher roller 203b-1 is parallel to the length direction of the pusher plate 203. When the pusher plate 203 pushes the moisture-proof liner, the pusher rollers 203b-1 at the upper and lower ends press the moisture-proof liner tightly against the outside of the reversed cement packaging bag, thereby making the moisture-proof liner adhere tightly to the cement packaging bag.

[0033] Furthermore, a motor cylinder 301 is fixedly installed at the lower end of the platform of the base frame 3. A motor sleeve 301a is fixedly installed at the telescopic end of the motor cylinder 301. The motor sleeve 301a is fixedly sleeved on the outside of the sleeve shaft motor 202. The length direction of the telescopic shaft of the motor cylinder 301 points towards the bag assembly 1. After the moisture-proof liner is sleeved, the motor cylinder 301 pulls the sleeve shaft motor 202 to move, preventing the sleeve plate 201a and the bag plate 101a from moving away from each other, and preventing the gap between them from being too small to rotate.

[0034] The operation process in this embodiment is as follows: The moisture-proof liner is placed on the outside of the liner plate 201a. The liner shaft motor 202 drives the liner rotating shaft 201 to rotate, so that the liner plate 201a with the moisture-proof liner faces the bag plate 101a with the cement packaging bag inside. The liner pushing cylinder 204 pulls the push plate sleeve 204a to move, so that the push plate 203 moves towards the bag assembly 1, thereby pushing the moisture-proof liner outside the liner plate 201a towards the outside of the bag plate 101a with the cement packaging bag inside. The push rollers 203b-1 at the upper and lower ends press the moisture-proof liner tightly against the outside of the cement packaging bag, so that the moisture-proof liner is close to the cement packaging bag. After the moisture-proof liner is completed, the motor cylinder 301 pulls the liner shaft motor 202 to move, to prevent the liner plate 201a and the bag plate 101a from moving away, and to prevent the gap between them from being too small to rotate.
