[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 As shown, a hot stamping machine for plastic products includes an L-shaped base 1. A lifting assembly 6 is fixedly connected to the front of the upper part of the L-shaped base 1. A hot stamping roller 7 is rotatably connected to the inner wall of the lower part of the lifting assembly 6. A drive frame 2 is fixedly connected to the bottom of the inner wall of the L-shaped base 1 and is located below the hot stamping roller 7. A rotating seat 3 is rotatably connected to the right side of the drive frame 2 and is located below the hot stamping roller 7. Plastic product fixing assemblies 4 are rotatably connected to the inner cavities of the upper, lower, front and rear parts of the rotating seat 3. An auxiliary assembly 5 is fixedly connected to the front of the drive frame 2. The right side of the auxiliary assembly 5 is engaged with the left side of the plastic product fixing assembly 4 located in the front part.

[0029] First, the plastic product is fitted onto the outer wall of the plastic product fixing component 4. Then, the auxiliary component 5 is activated to engage the plastic product fixing component 4. Next, under the action of the auxiliary component 5, the right part of the plastic product fixing component 4 opens, thus providing internal support and fixation for the plastic product. Then, under the action of the motor inside the drive frame 2, the rotating seat 3 drives the four plastic product fixing components 4 to rotate, so that the fixed plastic product can move directly below the hot stamping roller 7. Then, under the action of the lifting component 6, the hot stamping roller 7 can move down to the upper surface of the outer wall of the plastic product, thereby performing hot stamping processing on the plastic product. At the same time, the plastic product below, after being hot stamped and cooled, can move to the right side of the auxiliary component 5. Then, under the action of the auxiliary component 5, the plastic product fixing component 4 can shrink, thereby removing the processed plastic product.

[0030] like Figure 2 , Figure 3 As shown, the auxiliary component 5 includes a fixed housing 51, the rear of which is fixedly connected to the front of the drive frame 2. A motor 54 is fixedly connected to the inner cavity of the fixed housing 51. A cross rod 55 is fixedly connected to the output end of the motor 54. The outer wall of the left part of the cross rod 55 is rotatably connected to the inner cavity of the fixed housing 51. A moving rod 56 is inserted into the outer wall of the cross rod 55 and is located between the fixed housing 51 and the rotating seat 3. A locking block 57 is fixedly connected to the right side of the moving rod 56.

[0031] The motor 54 is started by pressing the button, which causes the cross bar 55 to drive the moving bar 56 to rotate. This causes the locking block 57 to drive the threaded rod 43 to rotate, thereby unfolding the four support plates 46 to support and fix the plastic products. The operation is convenient.

[0032] like Figure 4As shown, two sliding rods 52 are fixedly connected to the right side of the fixed shell 51, and the two sliding rods 52 are located at the front and rear sides of the cross rod 55 respectively. A hydraulic rod 58 is fixedly connected to the inner cavity of the upper part of the fixed shell 51. A limit bracket 53 is fixedly connected to the output end of the hydraulic rod 58. The inner cavities of the front and rear parts of the limit bracket 53 are slidably connected to the outer walls of the two sliding rods 52 respectively. The inner cavity of the middle part of the limit bracket 53 is rotatably connected to the outer wall of the moving rod 56 respectively.

[0033] The hydraulic rod 58 causes the limiting bracket 53 to move to the right under the guidance of the two sliding rods 52, thereby engaging the outer wall of the locking block 57 with the inner wall of the left part of the threaded rod 43. At the same time, the limiting bracket 53 restricts the limiting shaft 41, thus facilitating the rotation of the threaded rod 43.

[0034] like Figure 5 As shown, the outer wall of the locking block 57 is engaged with the inner wall of the left part of the threaded rod 43, and the inner wall of the right part of the limiting bracket 53 is engaged with the front and rear sides of the left part of the limiting shaft 41 respectively.

[0035] The limiting bracket 53 restricts and fixes the limiting shaft 41. Then, under the action of the locking block 57, the threaded rod 43 can be connected with the moving rod 56, the cross rod 55 and the motor 54, thereby facilitating loading and unloading.

[0036] like Figure 6 As shown, the plastic product fixing assembly 4 includes a limiting shaft 41. The outer wall of the middle part of the limiting shaft 41 is rotatably connected to the inner cavity of the rotating seat 3. A limiting frame 42 is fixedly connected to the right side of the limiting shaft 41. Threaded rods 43 are rotatably connected to the inner cavities of the left and right parts of the limiting frame 42. The outer wall of the left part of the threaded rod 43 is rotatably connected to the inner cavity of the limiting shaft 41. Threaded sleeves 44 overlap on the opposite surfaces of the left and right parts of the limiting frame 42. The inner cavities of the two threaded sleeves 44 are threadedly connected to the outer walls of the threaded rods 43, and the inner cavities of the two threaded sleeves 44 are movably sleeved on the outer wall of the middle part of the limiting frame 42. Push plates 45 are rotatably connected to the inner walls of the upper, lower, front, and rear parts of the two threaded sleeves 44. Four support plates 46 are rotatably connected to the opposite surfaces of the eight push plates 45.

[0037] The limiting bracket 42 enables the two threaded sleeves 44 to move towards each other under the action of the threaded rod 43, thereby pushing the eight push plates 45 to unfold outward. Driven by the eight push plates 45, the four support plates 46 can be pushed to the upper, lower, front, and rear sides of the inner wall of the plastic product, thereby supporting and fixing the plastic product and improving the stability of the fixation.

[0038] like Figure 7 As shown, four support plates 46 and eight push plates 45 are located on the outside of the threaded rod 43, and an arc-shaped rubber support block 47 is fixedly connected to the side of the support plate 46 away from the threaded rod 43.

[0039] The curved rubber support block 47 enables the four support plates 46 to more stably support and restrict the inner wall of the plastic product when fixing it, without damaging the inner wall of the plastic product, thus playing a protective role.

[0040] The working principle of this utility model is as follows: First, the plastic product is fitted onto the outer wall of the four arc-shaped rubber support blocks 47. Then, the hydraulic rod 58 is activated by pressing a button, causing the limiting bracket 53 to move to the right under the guidance of the two sliding rods 52. This causes the outer wall of the locking block 57 to engage with the inner wall of the left part of the threaded rod 43. At the same time, the limiting bracket 53 restricts the limiting shaft 41. Next, the motor 54 is activated by pressing a button, causing the cross rod 55 to drive the moving rod 56 to rotate. This causes the locking block 57 to drive the threaded rod 43 to rotate, thereby unfolding the four support plates 46. Through the action of the arc-shaped rubber support blocks 47, the four support plates 46 can secure the plastic product. The inner wall is more securely supported and restricted without damaging the inner wall of the plastic product. Then, under the action of the motor inside the drive frame 2, the rotating seat 3 can drive the four limiting shafts 41 to rotate, so that the fixed plastic product can be moved to the bottom of the hot stamping roller 7. Then, under the action of the lifting component 6, the hot stamping roller 7 can be moved down to the upper surface of the outer wall of the plastic product to perform hot stamping processing on the plastic product. At the same time, the plastic product that has been hot stamped and cooled can be moved to the right side of the fixed shell 51. Then, under the action of the clamping block 57 and the limiting bracket 53, the four support plates 46 can return to their original positions, so that the processed plastic product can be removed.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
