The bottom wall of the guide rod 25 is flush with the bottom wall of the handle 20. The handle 20 passes through the through hole. The base 5 is aligned with the mounting groove on the top wall of the body 1 and inserted. The guide rods 25 at the four corners of the base 5 (penetrating the bottom wall of the mounting groove) guide the base 5 into precise position. The front of the body 1 is also provided with a guide rail door 26 to close the cavity. The operator opens the guide rail door 26 from the front of the body 1, inserts it into the cavity, and rotates the handle 20 through the through hole. The handle 20 drives the worm gear 22 in the movable cavity of the base 5 to rotate. The worm gear 22 meshes with the worm wheel 21, driving the screws 23 on both sides of the worm wheel 21 to rotate synchronously. The screws 23 drive the storage groove. The insert 24 extends along the groove: one end is inserted into the slot on the side wall of the mounting groove of the machine body 1 to achieve rigid fixation between the base 5 and the machine body 1. The worm gear 21 and worm 22 transmission have "reverse self-locking property". Even if the handle 20 stops rotating, the insert 24 will not retract on its own. After the entire load-bearing component is fixed, there is no looseness, which provides a stable foundation for subsequent positioning and heat transfer. In this embodiment, the first alignment component includes a first motor 6, a first guide rail 7, and a first bracket. 8. A first positive and negative toothed rod 9, a first slider 10, a first clamping plate 11, and a top plate 12. A first guide rail 7 is provided above the base 5. First supports 8 are symmetrically arranged on the left and right sides above the first guide rail 7. A first positive and negative toothed rod 9 is rotatably arranged between the two sets of first supports 8. Two sets of symmetrically arranged first sliders 10 are also provided on the first guide rail. A first clamping plate 11, threadedly connected to the first positive and negative toothed rod 9, is provided above the first slider 10. A top plate 12 is also provided above the two sets of first supports 8. The top plate 12 has left and right centering holes adapted to the first clamping plate 11. The first clamping plate 11 protrudes above the left and right centering holes. The output end of the first motor 6 passes through one set of the first supports 8 and is connected to the first positive and negative toothed rod 9. The second alignment component includes a second motor 13, a second guide rail 14, a second bracket 15, a second positive and negative toothed rod 16, a second slider 17, and a second clamping plate 18. The second brackets 15 are symmetrically arranged on the front and rear sides below the top plate 12. The second positive and negative toothed rods 16 are rotatably arranged between the two sets of second brackets 15. The bottom wall of the two sets of second brackets 15 is also provided with the second guide rail 14. The second guide rail 14 is arranged above the first guide rail 7. The second sliders 17 are symmetrically arranged on the front and rear sides above the second guide rail 14. The second sliders 17 are also provided with the second clamping plate 18, which is threadedly connected to the second positive and negative toothed rods 16. The top plate 12 is also provided with front and rear alignment holes that are adapted to the second clamping plate 18. The second clamping plate 18 protrudes from the front and rear alignment holes.

[0016] After the material is placed on the top plate 12, the positioning system is activated. The first centering component (left-right direction) and the second centering component (front-back direction) work together to achieve precise positioning. The top wall of the material protrudes from the first clamping plate 11 and the second clamping plate 18 to ensure the stability of subsequent heat transfer printing operations. The first motor 6 is activated, with its output end passing through the first bracket 8 and driving the first positive and negative toothed rods 9 to rotate. The first positive and negative toothed rods 9 and... The first clamping plates 11 above the two sets of first sliders 10 are threaded together (in opposite directions), driving the two sets of first clamping plates 11 to move towards each other along the first guide rail 7. The left and right centering holes of the top plate 12 protrude above the first clamping plates 11, clamping the material synchronously from the left and right sides until the left and right centers of the material are aligned with the center of the hot press head 4. The second motor 13 is started synchronously or in stages. The motor drives the second positive and negative toothed rods 16 between the second brackets 15 to rotate. The second positive and negative toothed rods 16 drive the two sets of second sliders 17 and the second clamping plates 18 above them to move towards each other along the second guide rail 14 (erected above the first guide rail 7 without spatial interference). The second clamping plates 18 protrude from the front and rear centering holes of the top plate 12, clamping the material from the front and rear sides (the clamping force is consistent with the left and right directions), so that the front and rear centers of the material are aligned with the center of the hot press head 4. After the double centering components are positioned in coordination, the deviation between the overall center of the material and the center of the hot press head 4 is ≤0.1mm, which is far superior to the traditional scale tooth positioning, ensuring the accurate position of the transferred pattern. In this embodiment, the supporting component also includes an auxiliary cover 19. The upper edge of the base 5 is provided with a supporting groove. The lower part of the auxiliary cover 19 is inserted into the supporting groove. The top wall of the auxiliary cover 19 is also provided with an auxiliary hole that matches the top plate 12. The insert block 24 in the storage state first passes through the auxiliary hole to complete the assembly of the auxiliary cover 19 and the base 5, and then inserts into the slot to complete the assembly of the base 5 and the body 1. During heat transfer printing, a heat transfer drawing is placed below the heat press head 4. The heat transfer drawing is often fed in conjunction with an intermittent feeding structure and used in conjunction with the heat press equipment. The lifting device 3 uses a cylinder to drive the heat press head 4 to feed intermittently and complete the heat transfer operation.
