Description

Technical Field

[0001] This utility model belongs to the field of plastic bag adhesive scraping technology, and in particular relates to a plastic bag adhesive scraping device. Background Technology

[0002] Sheet metal adhesives are high-performance materials used for bonding metal sheets. Their development stemmed from the limitations of traditional mechanical joining methods such as welding and riveting in terms of lightweighting, sealing, surface smoothness, and bonding of dissimilar materials. With the increasing demands for structural strength, weight reduction efficiency, and environmentally friendly processes in industries such as automotive, aerospace, electronics, and home appliances, sheet metal adhesives, with their uniform stress distribution, corrosion resistance, fatigue resistance, and adaptability to complex interfaces, are gradually becoming key process materials.

[0003] After production, sheet metal adhesives are packaged in 2-3 cubic meter drums for bulk transportation. The drums are made of metal, and since the adhesive is sticky, a plastic bag is placed inside the drum during filling to prevent direct contact between the adhesive and the drum. The adhesive is then filled into the plastic bag. Most adhesives are removed by extraction or repackaged into smaller packages. However, some adhesive residue remains in the folds and on the inner surface of the plastic bag. Traditionally, this is scraped off manually from the ground with tools, which is inefficient and time-consuming.

[0004] To address the aforementioned problems, this application proposes a plastic bag adhesive scraping device. Utility Model Content

[0005] The purpose of this invention is to provide a plastic bag adhesive scraping device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a plastic bag adhesive scraping device, comprising a bracket, with two sets of symmetrically arranged adapter rods hinged to the bottom of the bracket, and a first swing rod and a second swing rod symmetrically arranged fixed on the two sets of brackets respectively. An opening and closing mechanism for changing the angle of the first swing rod and the second swing rod is provided on one side of the lower end of the bracket. The front ends of the first swing rod and the second swing rod are provided with adhesive scraping mechanisms for clamping the plastic bag. The bracket is suspended by a mounting frame, and a hanging device is fixed above the mounting frame, located directly above the clamping part of the adhesive scraping mechanism.

[0008] Furthermore, the opening and closing mechanism includes a guide seat vertically fixed to the bottom of the bracket and a transition block slidably disposed in the guide seat. A connecting rod is hinged between the transition block and a symmetrical transition rod, and a pull rod is fixed to the bottom of the transition block.

[0009] Furthermore, the pull rod slides vertically in the guide seat, and a pull ring is fixed at the bottom of the guide seat.

[0010] Furthermore, the adhesive scraping mechanism includes a first clamping rod fixed to the inner side of the front end of the first swing arm and a drive rod rotatably installed in the second swing arm, wherein the drive rod has a second clamping rod on its side corresponding to the first clamping rod.

[0011] Furthermore, a handle is fixed to one end of the drive rod near the opening and closing mechanism, and a locking groove is provided at the end of the second rocker arm to be axially inserted into the handle.

[0012] Furthermore, locking rods are fixed at both ends of the first clamping rod, and locking plates that cooperate with the locking rods are fixed at both ends of the second clamping rod. The locking plates and locking rods are engaged by rotating the drive rod.

[0013] Furthermore, an axial sliding space is formed between the locking rod and the locking plate, which is greater than the distance required for the handle and the locking groove to engage.

[0014] This utility model has the following beneficial effects:

[0015] This utility model can be directly installed on the steel structure of the factory building using the mounting bracket. The lifting device can lift the plastic bag and place it in the clamping position of the adhesive scraping mechanism. The adhesive scraping mechanism can clamp the plastic bag. When the lifting device moves the plastic bag upward, it can scrape out the residual adhesive inside, which greatly improves efficiency compared to manual operation.

[0016] This invention features an opening and closing mechanism that allows for changes in the opening angles of the first and second swing arms. When open, it facilitates the hoisting of plastic bags, while when closed, it ensures the clamping stability of the adhesive scraping mechanism. The device is flexible in use and easy to operate.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figures 1-5 As shown, this utility model is a plastic bag scraping device, including a bracket 1. Two sets of symmetrically arranged adapter rods 11 are hinged to the bottom of the bracket 1. A first swing rod 2 and a second swing rod 3 are respectively fixed on the two sets of brackets 1. An opening and closing mechanism 4 is provided on one side of the lower end of the bracket 1 to change the angle of the first swing rod 2 and the second swing rod 3. The front end of the first swing rod 2 and the second swing rod 3 is provided with a scraping mechanism 5 to clamp the plastic bag. The bracket 1 is suspended by a mounting frame 6. A lifting device 7 is fixed above the mounting frame 6 and located directly above the clamping part of the scraping mechanism 5. The lifting device 7 can be an electric hoist, a hand hoist or other lifting device.

[0029] The opening and closing mechanism 4 includes a guide seat 41 vertically fixed to the bottom of the bracket 1 and a transition block 42 slidably disposed in the guide seat 41. A connecting rod 43 is hinged between the transition block 42 and the symmetrical transition rod 11. The connecting rod 43 can simultaneously drive the first swing rod 2 and the second swing rod 3 to change their angles under the movement of the transition block 42. Then, the stability is ensured by the sliding of the transition block 42 in the guide seat 41. A pull rod 44 is fixed at the bottom of the transition block 42.

[0030] The pull rod 44 slides vertically in the guide seat 41, and a pull ring 45 is fixed at the bottom of the guide seat 41. The sliding of the pull rod 44 in the guide seat 41 plays a stabilizing role.

[0031] The glue scraping mechanism 5 includes a first clamping rod 51 fixed to the inner side of the front end of the first swing rod 2 and a drive rod 52 rotatably installed in the second swing rod 3. The drive rod 52 has a second clamping rod 53 on its side corresponding to the first clamping rod 51. The first clamping rod 51 is the fixed end and the second clamping rod 53 is the active end.

[0032] The drive rod 52 has a handle 521 fixed at one end near the opening and closing mechanism 4. The two are located at the same end to facilitate the operation between the opening and closing mechanism 4 and the glue scraping mechanism 5. The end of the second swing rod 3 has a locking groove 54 that is axially inserted into the handle 521 to prevent the first clamping rod 51 and the second clamping rod 53 from opening and the locking rod 511 and the locking plate 531 from separating. The locking plate 531 is locked with the locking rod 511 through the groove to play a stabilizing role.

[0033] The first clamping rod 51 has locking rods 511 fixed at both ends, and the second clamping rod 53 has locking plates 531 fixed at both ends that cooperate with the locking rods 511. The locking plates 531 and the locking rods 511 are engaged by the rotation of the drive rod 52. The cooperation between the locking rods 511 and the locking plates 531 effectively enhances the stability of the first clamping rod 51 in holding the plastic bag.

[0034] The locking rod 511 and the locking plate 531 form an axial sliding space that is greater than the distance required for the handle 521 and the locking groove 54 to engage. This ensures that the handle 521 and the locking rod 511 are locked together, while facilitating the flexible engagement of the locking groove 54 and the handle 521. Moreover, it can be operated only through the handle 521, which provides high flexibility.

[0035] Understandably, by directly connecting the mounting frame to the steel structure of the factory, and using a lifting device to position the plastic bag at the clamping position of the adhesive scraping mechanism, the residual adhesive is scraped off by the adhesive scraping mechanism in conjunction with the upward movement of the lifting device, which significantly improves work efficiency. At the same time, the opening and closing mechanism dynamically adjusts the unfolding angle of the first and second swing arms, which combines the convenience of hoisting with the stability of clamping, making the device flexible and adaptable to operation.

[0036] A specific application of this embodiment is as follows: Pulling down the pull rod 44 via the pull ring 45 causes the pull rod 44 to move the adapter block 42 downwards within the guide seat 41. The guide seat 41 then moves the upper end of the connecting rod 43 downwards, causing the lower ends of the two connecting rods 43 to unfold the first swing rod 2 and the second swing rod 3. Figure 5 As shown, the plastic bag to be scraped is placed directly below the first clamping rod 51 and the second clamping rod 53. The lowering device 7 lifts the plastic bag upwards. The opening and closing mechanism 4 is pushed in the opposite direction to bring the first swing rod 2 and the second swing rod 3 closer together. The handle 521 is held, and the drive rod 52 is rotated to bring the first clamping rod 51 and the second clamping rod 53 closer together, forming a gap for the plastic bag to pass through. The second clamping rod 53 is rotated to retract the locking plate 531 and the locking rod 511. Then, the handle 521 is pushed axially to insert into the locking groove 54 to prevent the drive rod 52 from rotating in the second swing rod 3. The lifting device 7 is pulled upwards to scrape off the residual adhesive in the plastic bag.
