Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging barrel production, in particular to heat transfer equipment for the production of plastic packaging barrels. Background Art

[0002] Plastic packaging barrels have the advantages of being light, not fragile, corrosion-resistant and recyclable. Therefore, they are widely used in many fields today. Plastic packaging barrels are often used to store and package decorative architectural coatings. Nowadays, a film with a pattern is usually heat-transferred on the surface of the plastic packaging barrel to enhance the product's aesthetics and market competitiveness.

[0003] A search revealed an existing patent (publication number: CN221366216U) that discloses a thermal transfer device for producing plastic barrels. The device comprises a plastic barrel, a roller sleeved within the barrel, a rotating shaft mounted on one side of the roller, a chuck mounted on one side of the rotating shaft, a slot provided in the middle of the chuck, rollers meshingly mounted on either side of the slot, bearings mounted on either side of the roller, a bracket mounted on the outer side of the bearing, a compression spring mounted on one side of the bracket, a slide groove provided on the outer side of the compression spring, and a bearing seat mounted on the end of the rotating shaft. The present invention utilizes a shaft support structure that connects the chuck to the rotating shaft and a slot provided on the surface of the chuck, allowing the roller to lift the interior of the slot. This prevents the rotating shaft from bending during the stamping process, significantly protecting the rotating shaft and the roller. A buffer structure, utilizing the compression spring to maintain contact with the roller within the slot, prevents derailment during operation. Furthermore, the compression spring provides a certain degree of shock absorption.

[0004] However, in the above solution, during the actual production and processing, the inner diameters of plastic packaging barrels of different specifications are different, but the diameter of the existing fixing roller is fixed, which makes it inconvenient to firmly clamp and fix plastic packaging barrels of different inner diameters, resulting in low applicability of the device.

[0005] In view of this, the utility model provides a heat transfer device for producing plastic packaging barrels. Utility Model Content

[0006] The utility model provides a heat transfer device for producing plastic packaging barrels, which solves the problem in the related art that it is inconvenient to firmly clamp and fix plastic packaging barrels with different inner diameters.

[0007] The technical solution of the utility model is as follows: A thermal transfer device for producing plastic packaging barrels, comprising a base plate; a fixing frame fixedly connected to the top end of the base plate; a roller rotatably connected to the lower end of the front face of the fixing frame; a clamping assembly assembled at equal angles inside the roller, the clamping assembly being used to clamp and fix plastic packaging barrels of different inner diameters; a reduction motor fixedly connected to the lower end of the back face of the fixing frame, the output end of the reduction motor being fixedly connected to one end of the roller through a coupling; a pneumatic telescopic rod fixedly connected to the bottom end of the fixing frame, the output end of the pneumatic telescopic rod passing through the upper end of the fixing frame and fixedly connected to a hot press; guide rollers arranged on both sides above the base plate; and adjustment components symmetrically assembled on both sides of the top end of the base plate, the adjustment components being used to adjust the height of the guide rollers.

[0008] The clamping assembly includes: reserved grooves opened at equal angles on the surface of the drum; fixed grooves symmetrically opened on the bottom wall of the reserved grooves; an electric telescopic rod fixedly connected to the bottom wall of the fixed groove, the output end of the electric telescopic rod fixedly connected to a sliding plate; and a rubber pad fixedly connected to the top of the sliding plate.

[0009] Preferably, the top end of the sliding plate is provided with anti-slip grooves at equal angles, and the anti-slip grooves are in an arc shape.

[0010] Preferably, the height of the sliding plate and the rubber pad is less than the depth of the reserved groove, and the sliding plate and the rubber pad have three equal angles respectively.

[0011] Preferably, the adjustment assembly includes: a fixing seat symmetrically fixedly connected to both sides of the top of the base plate; an adjustment slot opened in the middle position of the front of the fixing seat; a threaded rod rotatably connected to the inner wall of the adjustment slot, and a threaded block is threadedly connected to the surface of the threaded rod; a vertical plate fixedly connected to the front of the threaded block, and the upper end of one end of the vertical plate is rotatably connected to one end of the guide roller; a rotating handle rotatably connected to the top of the fixing seat, and the bottom end of the rotating handle is fixedly connected to the top of the threaded rod.

[0012] Preferably, a friction block is fixedly connected to one side of the top end of the fixing seat, and one side of the friction block is arc-shaped.

[0013] Preferably, slide grooves are provided on both sides of the front surface of the fixing seat, and sliders that slide in cooperation with the inside of the slide grooves are fixedly connected to the lower ends of both sides of the back surface of the vertical plate.

[0014] Preferably, an auxiliary groove is provided in an annular manner at the lower end of the inner wall of the fixing frame, and an auxiliary block which is slidably matched with the inside of the auxiliary groove is fixedly connected to the back side of the drum at an equal angle.

[0015] Preferably, reinforcement blocks are welded to the lower ends of both sides of the fixing frame, and the bottom ends of the reinforcement blocks are welded to the top end of the bottom plate.

[0016] The beneficial effects of the utility model are:

[0017] The utility model uses a clamping assembly and a roller to sleeve a plastic packaging barrel on the surface of the roller. Then, the electric telescopic rod is activated to slide the sliding plate and drive the rubber pad to cling to the inner wall of the plastic packaging barrel. The anti-slip grooves are used to increase the anti-slip property of the contact between the two, thereby improving the firmness and stability of the plastic packaging barrel sleeve. In addition, the slidable sliding plate and rubber pad can clamp and fix plastic packaging barrels with different inner diameters, avoiding the limitations caused by the fixed roller diameter, thereby improving the applicability of the equipment and facilitating transfer processing on the surfaces of plastic packaging barrels with different inner diameters.

The height of the guide roller can be adjusted according to the horizontal plane height of the top end of the plastic packaging barrel after sleeve installation, thereby ensuring that the film can be more accurately transferred to the surface of plastic packaging barrels with different inner diameters. At the same time, the slidable guide roller can also ensure the tension of the film, thereby ensuring the transfer quality. The friction block can cause a certain obstruction to the rotation of the rotating handle to prevent the rotating handle from being accidentally touched, which will cause the rotation of the threaded rod, thereby causing the height of the guide roller to change.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0027] The preferred embodiment of the heat transfer equipment for producing plastic packaging barrels provided by the utility model is as follows Figures 1 to 5 As shown: A thermal transfer device for the production of plastic packaging barrels, including a base plate 7; a fixing frame 1 fixedly connected to the top of the base plate 7; a roller 3 rotatably connected to the lower end of the front side of the fixing frame 1; a clamping assembly 2 assembled at equal angles inside the roller 3, the clamping assembly 2 is used to clamp and fix plastic packaging barrels with different inner diameters; a reduction motor 10 fixedly connected to the lower end of the back side of the fixing frame 1, the output end of the reduction motor 10 is fixedly connected to one end of the roller 3 through a coupling; a pneumatic telescopic rod 9 fixedly connected to the bottom end of the fixing frame 1, the output end of the pneumatic telescopic rod 9 passes through the upper end of the fixing frame 1 and is fixedly connected to a hot press 8; guide rollers 4 are arranged on both sides above the base plate 7; and adjustment components 5 are symmetrically assembled on both sides of the top of the base plate 7, the adjustment components 5 are used to achieve height adjustment of the guide rollers 4.

[0028] The clamping assembly 2 includes: a reserved groove 203 opened at an equal angle on the surface of the roller 3; a fixed groove 202 symmetrically opened on the bottom wall of the reserved groove 203; an electric telescopic rod 201 fixedly connected to the bottom wall of the fixed groove 202, and the output end of the electric telescopic rod 201 is fixedly connected to the sliding plate 204; and a rubber pad 205 fixedly connected to the top of the sliding plate 204.

[0029] It should be noted that the existing thermal transfer equipment for the production of plastic packaging barrels still has certain shortcomings in actual use. In the actual production and processing process, the inner diameters of plastic packaging barrels of different specifications are different, but the diameter of the existing fixing roller 3 is fixed, which makes it inconvenient to firmly clamp and fix plastic packaging barrels with different inner diameters, resulting in low applicability of the device.

[0030] In this embodiment, the plastic packaging barrel is first placed on the surface of the roller 3, and then the electric telescopic rod 201 is started, so that the sliding plate 204 slides and drives the rubber pad 205 to be close to the inner wall of the plastic packaging barrel, thereby improving the firmness and stability of the plastic packaging barrel. The sliding plate 204 and the rubber pad 205 can be used to clamp and fix plastic packaging barrels with different inner diameters, thereby improving their applicability. Then, the height of the guide roller 4 is adjusted according to the horizontal height of the top of the plastic packaging barrel after the placement. At this time, the adjustment component 5 is used to perform this operation, so that the patterned film can be more accurately transferred to the plastic packaging barrel. The surface of the barrel, at the same time, the slidable guide roller 4 can also ensure the tension of the film, thereby ensuring the transfer quality, and then start the pneumatic telescopic rod 9 to make the heat press 8 descend, and at the same time start the reduction motor 10 to make the roller 3 rotate to drive the plastic packaging barrel to rotate, and then cooperate with the heat press 8 to transfer the pattern to the surface of the plastic packaging barrel. After the transfer is completed, the pneumatic telescopic rod 9 works to make the heat press 8 rise, and then the reduction motor 10 stops working, and the sliding plate 204 and the rubber pad 205 are retracted, which makes it easier for the staff to remove the plastic packaging barrel from the roller 3, and repeat the above operation to realize the transfer processing of the plastic packaging barrel.

[0031] In a further preferred embodiment of the present invention, anti-slip grooves 206 are formed at equal angles on the top of the sliding plate 204 , and the anti-slip grooves 206 are arc-shaped.

[0032] In this embodiment, the anti-slip grooves 206 are used to increase the anti-slip property of the contact between the two, further improving the firmness of the plastic packaging barrel after installation.

[0033] In a further preferred embodiment of the present invention, the height of the sliding plate 204 and the rubber pad 205 is less than the depth of the reserved groove 203, and the sliding plate 204 and the rubber pad 205 have three equal angles respectively.

[0034] In this embodiment, a deeper reserved groove 203 is used so that the sliding plate 204 and the rubber pad 205 can completely enter the reserved groove 203, thereby preventing the rubber pad 205 from protruding from the surface of the drum 3 and causing inconvenience in installing or removing the plastic packaging barrel. Example 2

[0036] In this embodiment, the threaded rod 503 is driven to rotate by turning the handle 509 with greater force, and the threads of the threaded rod 503 and the threaded block 504 are matched to make the threaded block 504 slide and drive the vertical plate 501 to slide up and down, thereby causing the guide roller 4 to move accordingly, so that the height of the guide roller 4 can be adjusted according to the horizontal plane height of the top of the plastic packaging barrel after being installed, ensuring that the film can be more accurately transferred to the surface of plastic packaging barrels with different inner diameters. At the same time, the slidable guide roller 4 can also ensure the tension of the film, thereby ensuring the transfer quality.

[0037] In a further preferred embodiment of the present invention, a friction block 508 is fixedly connected to one side of the top of the fixing seat 502 , and one side of the friction block 508 is arc-shaped.

[0038] In this embodiment, the friction block 508 can hinder the rotation of the handle 509 to a certain extent, thereby preventing the handle 509 from being accidentally touched and causing the threaded rod 503 to rotate, thereby causing the height of the guide roller 4 to change.

[0039] In a further preferred embodiment of the present invention, slide grooves 507 are provided on both sides of the front of the fixing seat 502 , and sliders 505 that slide in cooperation with the inside of the slide grooves 507 are fixedly connected to the lower ends of both sides of the back of the vertical plate 501 .

[0040] In this embodiment, the sliding of the slider 505 and the inner portion of the sliding groove 507 is utilized to improve the stability of the vertical plate 501 sliding up and down.

[0043] In a further preferred embodiment of the present invention, reinforcement blocks 6 are welded to the lower ends of both sides of the fixing frame 1 , and the bottom ends of the reinforcement blocks 6 are welded to the top ends of the bottom plates 7 .

[0044] In this embodiment, the welded reinforcement block 6 is used to improve the structural strength of the connection between the bottom end of the fixing frame 1 and the top end of the bottom plate 7, thereby ensuring the firmness and stability of the fixing frame 1 after installation.

[0045] In summary, by utilizing the clamping component 2, the roller 3 can be securely mounted with plastic packaging barrels of different inner diameters, thereby improving its applicability. The adjusting component 5 can be used to adjust the height of the guide roller 4, so that the height of the guide roller 4 can be adjusted according to the horizontal plane height of the top of the plastic packaging barrel after mounting, thereby ensuring that the film can be more accurately transferred to the surface of plastic packaging barrels of different inner diameters. At the same time, the slidable guide roller 4 can also ensure the tension of the film, thereby ensuring the transfer quality.
