Description

Technical Field

[0001] This invention relates to the field of hot stamping equipment technology, specifically to a device and method for uniformly hot stamping the surface of conical flasks. Background Technology

[0002] Although some existing hot stamping equipment uses a method of rotating the hot stamping foil during the hot stamping process, the actual processing effect is not very good.

[0003] For example, Chinese patent document CN22118820U, entitled "A Hot Stamping Equipment for Bottle Decoration Processing," details a hot stamping equipment for bottle decoration processing, including a mounting frame, a swing component, a lifting mechanism, and a motion compensation component. When the lifting mechanism drives the rubber roller to descend, it presses the hot stamping foil firmly against the surface of the substrate to be hot stamped. By incorporating the swing component and the motion compensation component, the rubber roller presses the hot stamping foil at a specific angle to the hot stamping position on the bottle, ensuring even hot stamping of the fan-shaped surface with consistent travel distance. This avoids uneven patterns, meets the needs of different products, and solves the problem of uneven patterns when hot stamping conical bottles with existing equipment, demonstrating broad market prospects.

[0004] The aforementioned prior art does not consider the relationship between the axis of rotation of the hot stamping foil and the diameter of the cone apex of the conical bottle, nor does it consider that the conical bottle can rotate until the waistline coincides with the horizontal plane, so that the hot stamping area, the hot stamping foil, and the hot stamping head are in line contact. Therefore, the overall effect on pattern improvement is still relatively poor. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device and method for uniformly hot stamping gold on the surface of a conical flask, which can solve the problems in the prior art.

[0006] This invention is achieved through the following technical solution: A device for uniformly hot stamping the surface of a conical flask, comprising a vertical straight-line module, on which a horizontal straight-line module is fixedly mounted. The device is characterized in that a first sliding mechanism is fixedly installed on the slider of the horizontal straight-line module, a first sliding plate is fixedly mounted on the slider of the first sliding mechanism, an electric turntable is fixedly mounted in the first sliding plate, a second sliding plate is fixedly mounted on the rotating shaft of the electric turntable, a second sliding mechanism is fixedly mounted on the second sliding plate, a sliding plate is fixedly mounted on the slider of the second sliding mechanism, and a connecting arm is fixedly mounted on one side of the sliding plate. A third sliding mechanism is fixedly installed, one of which is equipped with a hot stamping foil release mechanism, and the other with a hot stamping foil winding mechanism. Hot stamping foil is placed between the hot stamping foil release mechanism and the hot stamping foil winding mechanism. The system also includes a clamping mechanism, which holds a conical bottle. The clamping mechanism swings the conical bottle until the upper projection line of the vertical section of the conical surface coincides with the horizontal plane. A hot stamping head is fixedly connected to the slider of the horizontal straight module above the clamping mechanism. The hot stamping foil moves to the hot stamping area on the surface of the conical bottle. The hot stamping foil, the pressure roller of the hot stamping head, and the conical surface of the conical bottle are in line contact.

[0007] The present invention discloses a method for operating a uniform hot stamping device for the surface of a conical flask: First, a first sliding mechanism drives an electric turntable to be positioned at the apex of the conical surface of the flask, with the rotation axis of the electric turntable coinciding with the apex of the conical surface; Second, the second sliding mechanism drives a sliding plate, a connecting arm, a hot stamping foil release mechanism, and a hot stamping foil winding mechanism to move back and forth, moving the hot stamping foil to the hot stamping area on the surface of the conical flask; Third, the vertical linear module drives a horizontal linear module and, connected to the horizontal linear module, a first sliding mechanism, a second sliding mechanism, a second sliding plate, a sliding plate, an electric turntable, a connecting arm, and a hot stamping head, to move downwards, causing the pressure roller of the hot stamping head to contact the hot stamping foil with the conical surface of the flask; Fourth, the electric turntable operates... Then, the second sliding plate, sliding plate, connecting arm, hot stamping foil release mechanism, and hot stamping foil winding mechanism are driven to rotate along an arc trajectory. At the same time, the hot stamping foil is released from the hot stamping foil release mechanism and wound up by the hot stamping foil winding mechanism. The hot stamping head heat-presses the hot stamping foil and forms it on the outer surface of the conical bottle. The conical bottle is also driven to rotate clockwise by the clamping mechanism. In the fifth step, the vertical straight module drives the horizontal straight module and the first sliding mechanism, second sliding mechanism, second sliding plate, sliding plate, electric turntable, connecting arm, and hot stamping head connected to the horizontal straight module to move upward and reset. After the electric turntable works, it drives the second sliding plate, sliding plate, connecting arm, hot stamping foil release mechanism, and hot stamping foil winding mechanism to reset and rotate along an arc trajectory.

[0008] The present invention discloses a method for operating a device for uniform hot stamping on the surface of a cylindrical bottle: First, by adjusting the first sliding mechanism and the second sliding mechanism, the sliding plate, connecting arm, hot stamping foil release mechanism, and hot stamping foil winding mechanism are moved back and forth, causing the hot stamping foil to move to the hot stamping area on the surface of the cylindrical bottle. Second, the vertical linear module drives the horizontal linear module and the first sliding mechanism, the second sliding mechanism, the second sliding plate, the sliding plate, the electric turntable, the connecting arm, and the hot stamping head connected to the horizontal linear module to move downwards, causing the pressure roller of the hot stamping head to contact the hot stamping foil with the surface of the cylindrical bottle. Third, the hot stamping foil is released from the hot stamping foil release mechanism and wound up by the hot stamping foil winding mechanism, and the hot stamping head forms the hot stamping foil on the outer surface of the cylindrical bottle, while the cylindrical bottle is also rotated clockwise by the clamping mechanism. Fourth, the vertical linear module drives the horizontal linear module and the first sliding mechanism, the second sliding mechanism, the second sliding plate, the sliding plate, the electric turntable, the connecting arm, and the hot stamping head connected to the horizontal linear module to move upwards and reset.

[0009] In a further technical solution, the vertex of the conical surface of the conical flask refers to the intersection of the oblique lines on both sides of the vertical cross-section of the conical flask.

[0010] A further technical solution includes a hot stamping head comprising a connecting seat fixedly connected to the slider of the transverse linear module. A plurality of optical rods are fixedly disposed on one side of the connecting seat. An internally threaded moving block is slidably disposed on the outer surface of the optical rod. An end block is fixedly disposed on one side of the optical rod. A third screw is rotatably disposed inside the end block. The third screw passes through the internally threaded moving block and is threadedly connected to the internally threaded moving block. A hot stamping component is disposed at the bottom of the internally threaded moving block.

[0011] A further technical solution includes a hot stamping assembly comprising a housing, a pressure roller rotatably disposed within the housing, multiple heating rods disposed within the housing, a pressure roller drive motor fixedly disposed on one side of the housing, a first sprocket being poweredly connected to the output shaft of the pressure roller drive motor, a second sprocket being fixedly disposed on the pressure roller, and the second sprocket and the first sprocket being poweredly connected via a chain.

[0012] In a further technical solution, the clamping mechanism includes a rotating seat, a rotating mating block rotatably disposed within the rotating seat, a mating plate fixedly disposed on the top of the rotating mating block, a base fixedly disposed on the top of the mating plate, a bottle rotating motor fixedly disposed on one side of the base, a squeezing cylinder fixedly disposed on the output shaft of the bottle rotating motor, a rotating motor fixedly disposed on one side of the rotating seat, and the output shaft of the rotating motor being poweredly connected to the rotating mating block to cause the rotating mating block to rotate.

[0013] In a further technical solution, a plurality of guide rods are fixedly installed on one side of the base, and a sliding bracket is slidably installed on the guide rods. A cylinder is fixedly installed at the bottom of the mating plate, and the push rod of the cylinder is fixedly connected to the sliding bracket. Connecting rods are fixedly installed on both sides of the sliding bracket, and a push plate is fixedly installed on one side of the connecting rod. An adsorption pin is rotatably installed on the push plate.

[0014] The beneficial effects of this invention are as follows: First, the first sliding mechanism adjusts the front and rear positions of the second sliding plate, sliding plate, electric turntable, connecting arm, hot stamping foil release mechanism, and hot stamping foil winding mechanism, so that the rotation axis of the winding motor coincides with the apex of the conical surface of the conical bottle. Second, the second sliding structure allows the hot stamping foil to move back and forth to the area of ​​the conical bottle to be hot stamped. The clamping mechanism swings the conical bottle until the upper projection line of the vertical section of the conical surface coincides with the horizontal plane, so that the part of the conical surface in contact with the horizontal plane is the oblique length of the conical surface. After the conical bottle is continuously driven to rotate by the clamping mechanism, the hot stamping foil also moves in a fan-shaped trajectory around the rotation axis of the electric turntable. When the hot stamping head presses the hot stamping foil onto the conical surface, the hot stamping foil, the pressure roller of the hot stamping head, and the conical surface of the conical bottle are in line contact to avoid relative movement that would cause the pattern to become blurred.

[0015] Second, the first sliding mechanism is beneficial for adjusting the position of the rotation axis of the electric turntable according to bottles with different tapers, so that the hot stamping foil forms an arc-shaped trajectory when rotating around the rotation axis of the electric turntable. This arc-shaped trajectory is exactly in contact with and consistent with the conical surface of the conical bottle in the hot stamping area, avoiding the formation of a movement angle between the hot stamping foil and the surface of the conical bottle due to the tangential movement of the hot stamping foil, which would affect the pattern forming.

[0016] Third, the clamping mechanism swings while clamping the conical bottle so that the outer surface of the conical bottle faces upward and its top waistline coincides with the horizontal plane, which also avoids the angle between the bottle and the hot stamping foil, thus affecting the pattern forming effect.

[0017] Fourth, the third sliding mechanism allows for a wider range of adjustment distances for the hot stamping foil release mechanism, hot stamping foil winding mechanism, and hot stamping foil when the conical bottle is inverted. This allows the hot stamping foil release mechanism, hot stamping foil winding mechanism, and hot stamping foil to be positioned on the outer surface of the conical bottle at the rear when the rotation axis of the electric turntable is in the front position.

Detailed Implementation

[0035] like Figures 1-15 As shown, the present invention will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 6 The directions of the projection relationship are consistent in all directions: up, down, left, right, front, and back.

[0036] like Figure 1 As shown, an apparatus for uniformly hot stamping the surface of a conical flask according to the present invention includes a vertical straight module 11, a horizontal straight module 12 fixedly mounted on the slider of the vertical straight module 11, a first sliding mechanism fixedly mounted on the slider of the horizontal straight module 12, a first sliding plate 69 fixedly mounted on the slider of the first sliding mechanism, an electric turntable 76 fixedly mounted in the first sliding plate 69, a second sliding plate 68 fixedly mounted on the rotating shaft of the electric turntable 76, a second sliding mechanism fixedly mounted on the second sliding plate 68, a sliding plate 71 fixedly mounted on the slider of the second sliding mechanism, a connecting arm 64 fixedly mounted on one side of the sliding plate 71, a third sliding mechanism fixedly mounted on the connecting arm 64, a hot stamping foil release mechanism fixedly mounted on one of the third sliding mechanisms, a hot stamping foil winding mechanism fixedly mounted on the other third sliding mechanism, hot stamping foil continuously moving in the hot stamping foil release mechanism and the hot stamping foil winding mechanism, and a clamping mechanism 14, in which the conical flask is clamped, and a hot stamping head 53 fixedly connected to the slider of the horizontal straight module 12 is mounted above the clamping mechanism 14; as Figure 5As shown, the hot stamping foil moves to the hot stamping area on the surface of the conical bottle. The hot stamping foil, the pressure roller of the hot stamping head 53, and the conical surface of the conical bottle are in line contact. The clamping mechanism 14 swings the conical bottle until the upper projection line of the vertical section of the conical surface coincides with the horizontal plane, so that the part of the conical surface in contact with the horizontal plane is the oblique length of the conical surface. After the conical bottle is continuously driven to rotate by the clamping mechanism 14, the hot stamping foil also moves in a fan-shaped trajectory around the rotation axis of the electric turntable 76. When the hot stamping head 53 presses the hot stamping foil to form the conical surface, the hot stamping foil, the pressure roller of the hot stamping head 53, and the conical surface of the conical bottle are in line contact to avoid relative movement that would cause the pattern to become blurred.

[0037] Advantageously, for cylindrical bottles without a conical surface, the clamping mechanism 14 is used to lay the cylindrical bottle flat, and then the positions of the hot stamping foil release mechanism, the hot stamping foil winding mechanism, and the hot stamping foil are adjusted by the first sliding mechanism and the second sliding mechanism so that the hot stamping foil is located in the hot stamping area of ​​the cylindrical bottle. The hot stamping head 53 can also be used for the hot stamping function of cylindrical bottles. In this case, it is not necessary for the electric turntable 76 to drive the hot stamping foil release mechanism, the hot stamping foil winding mechanism, and the hot stamping foil to rotate.

[0038] like Figure 2 , 3 As shown in Figure 4, the working method of the uniform hot stamping equipment for the surface of a conical flask according to the present invention is as follows: First, the first sliding mechanism drives the electric turntable 76 to be positioned at the apex of the conical surface of the conical flask, at which time the rotation axis of the electric turntable 76 coincides with the apex of the conical surface; Second, the second sliding mechanism drives the sliding plate 71, connecting arm 64, hot stamping foil release mechanism, and hot stamping foil winding mechanism to move back and forth, so that the hot stamping foil moves to the hot stamping area on the surface of the conical flask; Third, the vertical straight module 11 drives the horizontal straight module 12 and the first sliding mechanism, second sliding mechanism, second sliding plate 68, sliding plate 71, electric turntable 76, connecting arm 64, and hot stamping head 53 connected to the horizontal straight module 12 to move downwards, so that the pressure roller of the hot stamping head 53 contacts the hot stamping foil with the conical surface of the conical flask; Fourth, as shown in Figure 4. Figure 3As shown, after the electric turntable 76 operates, it drives the second slide plate 68, the sliding plate 71, the connecting arm 64, the hot stamping foil release mechanism, and the hot stamping foil winding mechanism to rotate along an arc trajectory. At the same time, the hot stamping foil is released from the hot stamping foil release mechanism and wound up by the hot stamping foil winding mechanism. The hot stamping head 53 hot-presses the hot stamping foil and forms it on the outer surface of the conical bottle. The conical bottle is also driven to rotate clockwise by the clamping mechanism 14 to achieve a more uniform pattern printing effect and avoid uneven printing caused by the conical surface. In the fifth step, the vertical straight module 11 drives the horizontal straight module 12 and the first sliding mechanism, the second sliding mechanism, the second slide plate 68, the sliding plate 71, the electric turntable 76, the connecting arm 64, and the hot stamping head 53 connected to the horizontal straight module 12 to move upward and reset. After the electric turntable 76 operates, it drives the second slide plate 68, the sliding plate 71, the connecting arm 64, the hot stamping foil release mechanism, and the hot stamping foil winding mechanism to reset and rotate along an arc trajectory.

[0039] Beneficially, among which, such as Figure 15 As shown, when the conical bottle is inverted, the vertex of the cone is located further forward. By adjusting the first sliding mechanism, the rotation axis of the electric turntable 76 is made to coincide with the vertex of the cone further forward. Then, the second sliding mechanism is used to adjust the position of the hot stamping foil release mechanism, the hot stamping foil winding mechanism, and the hot stamping foil so that they are located in the hot stamping area of ​​the conical bottle.

[0040] Advantageously, the working method of the equipment for uniform hot stamping on the surface of a cylindrical bottle according to the present invention is as follows: First, by adjusting the first sliding mechanism and the second sliding mechanism, the sliding plate 71, the connecting arm 64, the hot stamping foil release mechanism and the hot stamping foil winding mechanism are moved back and forth, so that the hot stamping foil is moved to the hot stamping area on the surface of the cylindrical bottle; Second, the vertical straight module 11 drives the horizontal straight module 12 and the first sliding mechanism, the second sliding mechanism, the second sliding plate 68, the sliding plate 71, the electric turntable 76, the connecting arm 64 and the hot stamping head 53 connected to the horizontal straight module 12. The hot stamping head 53 moves downward, causing the pressure roller of the hot stamping head 53 to contact the hot stamping foil with the surface of the cylindrical bottle; in the third step, the hot stamping foil is released from the hot stamping foil release mechanism and wound up by the hot stamping foil winding mechanism, and the hot stamping head 53 forms the hot stamping foil on the outer surface of the cylindrical bottle, while the cylindrical bottle is also rotated clockwise by the clamping mechanism 14; in the fourth step, the vertical straight module 11 drives the horizontal straight module 12 and the first sliding mechanism, the second sliding mechanism, the second sliding plate 68, the sliding plate 71, the electric turntable 76, the connecting arm 64 and the hot stamping head 53 connected to the horizontal straight module 12 to move upward and reset.

[0041] Beneficially, among which, such as Figure 12As shown, the first sliding mechanism includes a fixed plate 75 fixedly connected to the slider of the transverse linear module 12. A first sliding plate 69 is slidably provided on the fixed plate 75 via a guide rail slider structure. An internal thread block 67 is fixedly provided on one side of the first sliding plate 69. A first screw 66 is rotatably provided on one side of the fixed plate 75. The first screw 66 is threadedly connected to the internal thread block 67.

[0042] Beneficially, among which, such as Figure 12 As shown, the second sliding mechanism includes a guide rail slider structure that slidably connects the second slide plate 68 and the sliding plate 71. A second screw 72 is rotatably provided on one side of the second slide plate 68. The second screw 72 passes through the sliding plate 71 and is threadedly connected to it.

[0043] Beneficially, among which, such as Figure 12 As shown, the electric turntable 76 is fixedly installed in the first slide plate 69, and the second slide plate 68 is fixedly installed on the rotating shaft of the electric turntable 76.

[0044] When the first sliding mechanism is working, after rotating the first screw 66, the first screw 66 is threadedly connected to the internal thread block 67, causing the first slide plate 69 to slide back and forth relative to the fixed plate 75 through the guide rail slider structure. This adjusts the front and rear positions of the second slide plate 68, the sliding plate 71, the electric turntable 76, the connecting arm 64, the hot foil release mechanism, and the hot foil winding mechanism, so that the rotation axis of the winding motor 83 coincides with the apex of the conical surface of the conical bottle.

[0045] When the second sliding mechanism is working, after rotating the second screw 72, since the second screw 72 is threadedly connected to the sliding plate 71, the sliding plate 71, the connecting arm 64, the hot stamping foil release mechanism and the hot stamping foil winding mechanism can slide back and forth relative to the internal thread block 67 through the guide rail slider structure, so that the hot stamping foil can move back and forth to the area of ​​the conical bottle to be hot stamped.

[0046] Beneficially, among which, such as Figure 11 As shown, the hot stamping foil release mechanism includes a first plate 63 connected to the connecting arm 64. The position of the first plate 63 relative to the connecting arm 64 is adjusted by a third sliding mechanism. A material cylinder 62 is rotatably disposed inside the first plate 63. A feeding motor 61 is fixedly disposed on one side of the first plate 63. The feeding motor 61 drives the material cylinder 62 to rotate through a first synchronous belt pulley structure 85.

[0047] Beneficially, among which, such as Figure 11As shown, the hot stamping foil winding mechanism includes a second plate 84 connected to the connecting arm 64. The position of the second plate 84 relative to the connecting arm 64 is adjusted by a third sliding mechanism. A take-up cylinder 74 and a power cylinder 79 are rotatably arranged in the second plate 84. A tension roller 78 located on one side of the power cylinder 79 is also provided in the second plate 84. The tension roller 78 presses the hot stamping foil tightly onto the outer surface of the power cylinder 79. A winding motor 83 is provided on one side of the second plate 84. The winding motor 83 drives the power cylinder 79 to rotate through a second synchronous belt pulley structure 82. A belt 81 is provided between the power cylinder 79 and the take-up cylinder 74, and the belt 81 provides a power connection between the take-up cylinder 74 and the power cylinder 79.

[0048] Beneficially, among which, such as Figure 11 As shown, the third sliding mechanism includes a plurality of sliding rods 16 fixedly disposed on one side of the first plate 63 and the second plate 84. The sliding rods 16 are slidably connected to the connecting arm 64. A threaded shaft 17 is rotatably disposed on one side of the first plate 63 and the second plate 84. The threaded shaft 17 is threadedly connected to the connecting arm 64.

[0049] Beneficially, among which, such as Figure 11 and 15 As shown, by adjusting the third sliding mechanism, the hot stamping foil release mechanism, the hot stamping foil winding mechanism, and the front and rear positions of the hot stamping foil relative to the connecting arm 64 can also be adjusted to accommodate inverted conical bottles or provide a wider range of adjustment angles.

[0050] Beneficially, among which, such as Figure 11 As shown, multiple transition rods 77 are also fixedly installed on the lower side of the connecting arm 64. After the hot stamping foil is released from the hot stamping foil release mechanism, it passes through the outer surface of the transition rods 77 and is then wound into the hot stamping foil winding mechanism. The hot stamping foil is horizontally arranged between the hot stamping foil release mechanism and the hot stamping foil winding mechanism.

[0051] When the hot stamping foil release mechanism is working, the feeding motor 61 and the first synchronous belt pulley structure 85 drive the material cylinder 62 to rotate, releasing the hot stamping foil on the outer surface of the material cylinder 62. At the same time, the hot stamping foil winding mechanism also works. Through the structure of the winding motor 83, the second synchronous belt pulley structure 82, the belt 81, the take-up cylinder 74, the power cylinder 79 and the tensioning roller 78, the hot stamping foil is wound onto the outer surface of the take-up cylinder 74. After being guided by the transition rod 77 and tensioned by the tensioning roller 78, the hot stamping foil enters the hot stamping area in a flat and horizontal state.

[0052] Beneficially, among which, such as Figure 6 and Figure 9As shown, a hot stamping head 53 is provided above the hot stamping foil. Since the position of the hot stamping foil is adjustable, the position of the pressure roller in the hot stamping head 53 is also adjustable. The hot stamping head 53 includes a connecting seat 95 that is fixedly connected to the slider of the horizontal straight module 12. A plurality of light rods 91 are fixedly provided on one side of the connecting seat 95. An internal thread moving block 94 is slidably provided on the outer surface of the light rod 91. An end block 97 is fixedly provided on one side of the light rod 91. A third screw 92 is rotatably provided inside the end block 97. The third screw 92 passes through the internal thread moving block 94 and is threadedly connected to the internal thread moving block 94. A hot stamping component is provided at the bottom of the internal thread moving block 94.

[0053] After rotating the third screw 92, since the third screw 92 is threadedly connected to the internal thread moving block 94, the internal thread moving block 94 can be driven to slide back and forth on the smooth rod 91. This will also drive the internal thread moving block 94 and the hot stamping component to move back and forth, so that the hot stamping component can adapt to the position of the hot stamping foil.

[0054] Beneficially, among which, such as Figure 9 and 10 As shown, the hot stamping assembly includes a housing 96, a pressure roller is rotatably disposed inside the housing 96, a plurality of heating rods 55 are disposed inside the housing 96, a pressure roller drive motor 57 is fixedly disposed on one side of the housing 96, a first sprocket 58 is poweredly connected to the output shaft of the pressure roller drive motor 57, a second sprocket 54 is fixedly disposed on the pressure roller, and the second sprocket 54 and the first sprocket 58 are poweredly connected by a chain.

[0055] The pressure roller is driven by a motor 57, a second sprocket 54, a first sprocket 58 and a chain to rotate. The heating rod 55 generates heat to heat the pressure roller so that the pressure roller heats the hot stamping foil to form a pattern on the bottle. The pressure roller is usually equipped with a mold, which directly heats the hot stamping foil onto the bottle, thus forming a pattern on the bottle according to the shape on the mold.

[0056] Beneficially, among which, such as Figure 6 , 7As shown in Figure 8, the clamping mechanism 14 is located on the underside of the hot stamping foil. In actual installation, it is mounted on a frame in the external space. The clamping mechanism 14 includes a rotating base 37, within which a rotating mating block 43 is rotatably mounted. A mating plate 36 is fixedly mounted on the top of the rotating mating block 43, and a base 42 is fixedly mounted on the top of the mating plate 36. A bottle rotating motor 35 is fixedly mounted on one side of the base 42, and a squeezing cylinder 33 is fixedly mounted on the output shaft of the bottle rotating motor 35. A rotating cylinder is fixedly mounted on one side of the rotating base 37. The output shaft of the rotating motor 34 is connected to the rotating mating block 43 to make the rotating mating block 43 rotate. Multiple guide rods 39 are fixedly installed on one side of the base 42. A sliding bracket 38 is slidably installed on the guide rods 39. A cylinder 44 is fixedly installed at the bottom of the mating plate 36. The push rod of the cylinder 44 is fixedly connected to the sliding bracket 38. Connecting rods 41 are fixedly installed on both sides of the sliding bracket 38. A push plate 31 is fixedly installed on one side of the connecting rod 41. An adsorption pin 32 is rotatably installed on the push plate 31.

[0057] After the bottle is placed between the adsorption pin 32 and the extrusion cylinder 33, the cylinder 44 works and drives the sliding bracket 38, connecting rod 41, push plate 31 and adsorption pin 32 to move, so that the adsorption pin 32 presses the bottle against one side of the extrusion cylinder 33, so that the bottle rotation motor 35 drives the bottle to rotate through the extrusion cylinder 33. After the rotation motor 34 works, it drives the rotating mating block 43, mating plate 36, sliding bracket 38, base 42, guide rod 39, connecting rod 41, bottle rotation motor 35, extrusion cylinder 33, adsorption pin 32 and push plate 31 to rotate. The clamping mechanism 14 swings the conical bottle until the upper projection line of the vertical section of the conical surface coincides with the horizontal plane.

[0058] Beneficially, among which, such as Figure 6 and Figure 14 As shown, a pressing mechanism 15 for pushing the bottle upward is also provided below the clamping mechanism 14. The pressing mechanism 15 includes a housing 21. Two guide sliders 25 are fixedly installed inside the housing 21. A rack 27 is slidably installed inside the guide sliders 25. A lifting plate 24 is fixedly installed on the top of the rack 27. Multiple rollers 23 are rotatably installed on the top of the lifting plate 24. Two meshing gears 26 are rotatably installed in the housing 21. The gears 26 mesh with the rack 27. A lifting motor 22 is fixedly installed on the rear side of the housing 21. The lifting motor 22 is poweredly connected to one of the gears 26.

[0059] The lifting motor 22 drives one of the gears 26 to rotate. Since the gears 26 are meshed with each other, the other gear 26 also rotates. Since the gear 26 is meshed with the rack 27, the rack 27 moves upward within the guide slider 25. Since the rack 27 is connected and fixed to the lifting plate 24, the roller 23 pushes upward to press the bottle down, thus counteracting the downward pressure on the bottle during hot stamping.
