DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative labor are within the scope of protection of the present application.

[0025] As shown in Figures 1 to 5 A preheating device for carton die cutting includes a conveying table 101 and a cylinder 102, the output end of the cylinder 102 is fixedly provided with a cross plate 103, the cross plate 103 is fixedly provided with an outer shell 104, the outer shell 104 is fixedly provided with a heater 105, the heater 105 is fixedly provided with a telescopic pipe 112, the telescopic pipe 112 is fixedly provided with an output pipe 113, the output pipe 113 is fixedly provided with a main support rod 111 and a limiting frame 114, the main support rod 111 is slidably provided with an inner support rod 110 and a main support rod 111, the output pipe 113 is rotatably provided with a main gear ring 117, the main gear ring 117 is provided with a fan blade, and the fan blade is located inside the output pipe 113.

[0026] Specifically, the upper and lower ends of the output pipe 113 are fixed by external supports, and the limiting frame 114 can be replaced as needed to adapt to different heating ranges. In use, the paper box is moved to below the shell 104 by the conveying mechanism on the conveying table 101, and then the shell 104 is controlled to move downward by the air cylinder 102, so as to approach and contact the paper box on the conveying table 101, thereby fixing the paper box by the shell 104, avoiding the movement of the paper box driven by hot air during preheating, and avoiding the deviation and change of the heating position, thereby affecting the die cutting effect of the subsequent paper box.

[0027] During preheating, the heater 105 generates heat energy to heat air, and the rotation of the main tooth ring 117 on the output pipe 113 accelerates the hot air from the heater 105, enters the limiting frame 114 through the telescopic pipe 112 and the output pipe 113, thereby heating the part of the paper box that needs to be die cut.

[0028] After the limiting frame 114 contacts the paper box, the air cylinder 102 will continue to drive the horizontal plate 103 to move downward, and then the shell 104 will press the telescopic pipe 112 and the left slide rod 120 downward, so that the telescopic pipe 112 is folded due to the resistance of the heater 105 and the output pipe 113 in two directions. The left slide rod 120 is pushed to continue to move downward, thereby driving the control rod 119 to move downward on the screw rod 118, and then driving the screw rod 118 to rotate on the side support plate 115 through the threaded connection between the screw rod 118 and the control rod 119. The screw rod 118 drives the main tooth ring 117 to rotate through the side gear 116, and when the main tooth ring 117 rotates, the air in the output pipe 113 is driven to flow downward by the fan inside the output pipe 113, thereby assisting the hot air above to flow downward, improving the heating efficiency of the paper box.

[0029] When the heating is completed and the shell 104 is lifted, in the first stage, the shell 104 moves upward, and the limiting frame 114 keeps pressing the paper box. During this process, the shell 104 drives the control rod 119 to move upward on the screw rod 118 through the left slide rod 120, thereby driving the main tooth ring 117 to rotate in the opposite direction through the side gear 116, so that the air in the output pipe 113 flows from bottom to top. Because the paper box is fixed by the limiting frame 114, the paper box will not move, and when the control rod 119 moves to the upper end of the screw rod 118, the first stage ends and the second stage begins. The shell 104 drives the outer support rod 109, the inner support rod 110 and the main support rod 111 to move through the support block 106, thereby driving the limiting frame 114 to move upward together, so as to no longer limit the paper box, and the paper box can be moved to the next process by the conveying mechanism on the conveying table 101.

[0030] As Figure 2As shown, a side support plate 115 is fixedly installed on the output pipe 113, and a screw 118 is rotatably installed on the side support plate 115, with threads on the screw 118.

[0031] A left slide rod 120 is fixedly mounted on the outer casing 104, and a control rod 119 is slidably mounted on the left slide rod 120. The end of the control rod 119 near the screw 118 is threadedly connected to the screw 118. The connection between the left slide rod 120 and the control rod 119 is rectangular, so that when the left slide rod 120 moves up and down, it can drive the control rod 119 to move up and down on the screw 118.

[0032] The main support rod 111 has two vertical rods at one end near the left slide rod 120, and these two vertical rods are located on both sides of the control rod 119. Figure 2 As shown, the control lever 119 is inserted into the space between the two vertical bars on the main support rod 111. When the main support rod 111 moves left and right, the control lever 119 is pushed to slide left and right on the left slide rod 120 by the vertical bars.

[0033] A side gear 116 is fixedly mounted on the screw 118, and the side gear 116 meshes with the main gear ring 117.

[0034] like Figure 5 As shown, a horizontal shaft 121 is fixedly installed on the main support rod 111, and a plurality of limiting rods 122 are rotatably installed on the horizontal shaft 121. Adjacent limiting rods 122 are arranged in a centrally symmetrical manner. A torsion spring 123 is fixedly installed on the limiting rod 122, and the torsion spring 123 is also fixedly connected to the horizontal shaft 121. A connecting shaft 124 is fixedly installed between two limiting rods 122 in the same direction.

[0035] Specifically, the vertical plates around the outer casing 104 are removable, allowing for easy movement of the main support rod 111. A handle is located on the end of the main support rod 111 near the outer support rod 109. When moving the main support rod 111, the handle is manually controlled, while the other hand controls the two connecting shafts 124 to move closer together, thus releasing the fixation on the main support rod 111. Pushing the handle allows the main support rod 111 to move between the inner support rod 110 and the outer support rod 109, and the vertical rod of the main support rod 111 drives the control rod 119 to move on the left slide rod 120.

[0036] When adjusting the main support rod 111, manually control the two connecting shafts 124 to move in opposite directions, i.e. Figure 5As shown, control the two limit rods 122 on the left side of the main support rod 111, one counterclockwise rotation, one clockwise rotation, that is, both are rotated away from the inner support rod 110, the limit rod 122 is provided with an arc-shaped rod close to the inner support rod 110, the arc-shaped rod is matched with the groove on the inner support rod 110, so that when the arc-shaped rod of the limit rod 122 is inserted into the groove of the inner support rod 110, the arc-shaped rod is limited by the groove of the inner support rod 110, thereby limiting the movement of the main support rod 111 by the limit rod 122.

[0037] When the limit rod 122 rotates, the torsion spring 123 is twisted, and the limit rod 122 is reset by the torsion of the torsion spring 123, and the limit rod 122 is limited to avoid shaking, which affects the fixation of the main support rod 111.

[0038] As shown in Figure 4 When the limit frame 114 contacts the carton, the shell 104 presses the buffer spring 108 through the support block 106, so that the connecting rod 107 and the outer support rod 109 are pressed by the elastic force of the buffer spring 108, so that the connecting rod 107 slides on the support block 106, thereby buffering the force pressed by the downward movement of the shell 104 through multiple buffer springs 108.

[0039] As shown in Figure 2 The buffer spring 108 also generates a downward force on the right end of the main support rod 111, thereby driving the output pipe 113 to tilt to the right, and when the outer support rod 109 moves downward, the screw 118 is pressed downward by the left slide rod 120 and the control rod 119, thereby controlling the output pipe 113 to tilt to the left by the side support plate 115, thereby balancing the output pipe 113 and stabilizing the limit frame 114.

[0040] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
