Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and more specifically to a square barrel positioning mechanism for a heat transfer printing machine for applying film to square barrels. Background Technology

[0002] During the production process, the square buckets need to have a film applied to their surface for pattern transfer. Traditionally, pattern transfer involves manually placing the transfer film on the side wall of the bucket and then manually transferring the pattern onto the bucket body using a transfer plate. This method has a relatively low yield and poses significant safety risks.

[0003] To improve production efficiency, the traditional film transfer process for barrels has been gradually replaced by heat transfer machines. However, when using heat transfer machines to apply film to square barrels with special geometric shapes, positioning issues can easily lead to deviations, thus affecting the pass rate of the film application. Therefore, the positioning accuracy of the square barrel is crucial to the bonding quality between the transfer film and the barrel surface. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a square barrel positioning mechanism for a heat transfer printing machine for applying film to square barrels, so as to solve the problems in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0006] A square barrel positioning mechanism for a heat transfer printing machine for applying film to square barrels includes a chassis. A movable base is mounted on the chassis via a longitudinal movement module. A chassis is mounted on the movable base. A translation block is mounted on the chassis via a transverse movement module. A vertical plate is mounted on the translation block. A rotating block is mounted on the inner side of the vertical plate. Tensioning blocks for pressing against the inner wall of the square barrel are mounted around the rotating block via tensioning cylinders. A stepper motor for driving the rotating block to rotate is mounted on the outer side of the vertical plate. Several suction cups for adhering to the inner wall of the square barrel are mounted on the tensioning blocks. The suction cups are connected to a vacuum pump via air pipes. A PLC controller for controlling the positioning of the square barrel is installed inside the chassis. The output of the PLC controller is connected to the input of the tensioning cylinders, the stepper motor, and the vacuum pump.

[0007] To further optimize the technical solution, the longitudinal movement module includes a dovetail block longitudinally arranged on the chassis. The top of the dovetail block has a groove, and a screw is installed in the groove. The moving base is sleeved on the screw via an internal slider. A moving knob for adjusting the position of the moving base is provided on the outside of the dovetail block and connected to the screw.

[0008] To further optimize the technical solution, the transverse module includes a support plate vertically mounted on the side of the chassis. Two parallel guide rails are horizontally mounted on the chassis inside the support plate via guide rail mounting seats. The transverse block is slidably mounted on the guide rails. A transverse cylinder for driving the transverse block to move left and right is mounted on the outside of the support plate. The input end of the transverse cylinder is connected to the output end of the PLC controller.

[0009] To further optimize the technical solution, a photoelectric sensor for detecting the movement position of the translation block is installed on the chassis between the two guide rails, and the output end of the photoelectric sensor is connected to the input end of the PLC controller.

[0010] To further optimize the technical solution, the photoelectric sensor is mounted on the translation block via a photoelectric sensor mounting base. The photoelectric sensor mounting base has a mounting groove for adjusting the position of the photoelectric sensor, and the photoelectric sensor mounting base is fixed to the translation block by bolts passing through the mounting groove.

[0011] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0012] This utility model provides a square barrel positioning mechanism for a heat transfer machine for applying film to square barrels. The mechanism uses a movable clamping block to clamp the inner wall of the square barrel and a suction cup on the clamping block to hold the square barrel in place. This fixes the square barrel in place and allows the position of the square barrel to be adjusted according to its size, thus enabling the heat transfer machine to perform film transfer operations on the square barrel.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] A square barrel positioning mechanism for a heat transfer printing machine for applying film to square barrels, combined with Figs. 1 to 3As shown, it includes a chassis 1 and a PLC controller installed inside the chassis 1.

[0017] A movable base 22 is provided on the chassis 1 via a longitudinal movement module. The longitudinal movement module includes a dovetail block 21 on the chassis 1. A groove is provided on the top of the dovetail block 21, and a screw is provided in the groove. The inside of the movable base 22 is fitted onto the screw via a slider. The outside of the movable base is fitted onto the dovetail block. A movable knob 23 is provided on the outside of the dovetail block 21. The movable knob is connected to the screw and drives the screw to rotate, thereby realizing the longitudinal adjustment of the position of the movable base.

[0018] A chassis 24 is mounted on the mobile base 22. A translation block 27 is mounted on the chassis 24 via a lateral movement module. The lateral movement module includes a support plate 25 vertically mounted on the side of the chassis 24. Two parallel guide rails 29 are horizontally mounted on the chassis 24 inside the support plate 25 via a guide rail mounting seat 28. The translation block 27 is slidably mounted on the guide rails 29. A translation cylinder 26 is mounted on the outside of the support plate 25 to drive the translation block 27 to move left and right. The input end of the translation cylinder is connected to the output end of the PLC controller.

[0019] A vertical plate 210 is vertically mounted on the translation block 27. A rotating block 212 is mounted on the inner side of the vertical plate 210. Each of the four sides of the rotating block 212 is equipped with a clamping block 213 via a clamping cylinder 218, which is used to clamp the inner wall of the square bucket to fix the square bucket. A stepper motor 211 is mounted on the outer side of the vertical plate 210 to drive the rotating block 212 to rotate, thereby rotating the square bucket. After the heat transfer machine finishes applying film to one side of the square bucket, the stepper motor rotates the square bucket to apply film to the other side of the square bucket, until all four sides of the square bucket are covered with film.

[0020] Because the inner wall of the bucket is smooth, simply using the clamping block for fixation would allow the bucket to move easily during rotation. To ensure effective fixation, several suction cups 214 are installed on the clamping block 213 to hold the bucket in place. After the clamping block presses against the bucket, the suction cups hold it in place, ensuring a secure fixation. The suction cups are connected to a vacuum pump via air pipes. The input of the vacuum pump is connected to the output of a PLC controller. The PLC controls the vacuum pump to tighten and loosen the suction cups.

[0021] During the process of applying film to the square bucket on the top clamping block, the square bucket is moved to apply the film. A photoelectric sensor 217 is installed on the chassis 24 between the two guide rails 29 to detect the position of the square bucket. The output of the photoelectric sensor is connected to the input of the PLC controller.

[0022] The photoelectric sensor 217 is mounted on the translation block 27 via the photoelectric sensor mounting base 215. The photoelectric sensor mounting base has a mounting base groove 216. The photoelectric sensor mounting base is fixed to the translation block by bolts passing through the mounting base groove. The position of the photoelectric sensor is adjusted by the mounting base groove, thereby realizing the film application operation of square barrels of different sizes.

[0023] In this invention, when positioning the square bucket, the square bucket is fitted onto the clamping block on the rotating block. The clamping cylinder drives the clamping block to move outward, so that the four clamping blocks respectively abut against the inner wall of the square bucket. After the clamping blocks are tightened, the vacuum pump is started, and the suction cups hold the inner wall of the square bucket in place, thus fixing the square bucket in place. The square bucket will not move during rotation. During the film application process, the square bucket is moved by a translation motor, and the heat transfer machine applies film to the moving square bucket.
