Description

Technical Field

[0001] This utility model relates to the field of hot plate machine technology, specifically a hot plate machine for corrugated cardboard production. Background Technology

[0002] Corrugated cardboard is a type of board material consisting of a corrugated core layer and a cover layer formed between two or more layers of cardboard. It is commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", or "corrugated base paper".

[0003] Application number CN202420302890.0 discloses a hot plate machine for a corrugated cardboard production line, including a machine body, a drying cylinder, and a blower. In this application, a drive component drives a screw to rotate. The screw, through the engagement of a screw seat, provides a pushing force to a support plate. Simultaneously, the support plate drives a second drive roller and a second driven roller to adjust their vertical positions. A tension roller drives a slider to slide along the inside of a fixed chamber and compress a spring. The tension roller synchronously tensions the transmission belt, ensuring that the first drive roller is always stably linked with the second drive roller. Thus, while retaining the existing technology of drying cardboard using a drying cylinder and blower, it can adapt to cardboard of different thicknesses through automatic adjustment of the vertical position of the push belt. However, in practical use, this application lacks heat preheating recovery, resulting in slow preheating speed and high energy consumption. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0013] In a preferred embodiment, the present invention can be further configured such that: a reinforcing plate is sleeved on the outer side of the bidirectional electric push rod cylinder, and the reinforcing plate is fixedly connected to the front side wall of the inner cavity of the heat insulation channel.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, after the corrugated cardboard is passed through two rubber sheets that are bonded together, the external heat source device (hot air blower) is started.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of a hot plate machine for corrugated cardboard production.

[0032] Example 1:

[0033] Combination Figure 1-5 As shown, the present invention provides a hot plate machine for corrugated cardboard production, including a heating mechanism 100 and a heat collection mechanism 200. The heating mechanism 100 includes a heat insulation channel 110, a plurality of T-shaped tubes 120 penetrating through the front side wall of the heat insulation channel 110, two connecting tubes 130 inserted into the T-shaped tubes 120, a plurality of T-shaped rods 140 slidably embedded in the rear side wall of the inner cavity of the heat insulation channel 110, two connecting plates 150 connecting the connecting tubes 130 and the T-shaped rods 140, and a thin-walled roller 170 connected between the connecting tubes 130 and the T-shaped rods 140 through a bearing 160.

[0034] The heat collection mechanism 200 includes two hot air chambers 210 formed on the T-shaped rod 140, a plurality of guide rods 220 installed on the front and rear sides of the heat insulation channel 110, two rubber plates 230 slidably connected between the two opposing guide rods 220, and a sleeve 240 threadedly connected to the guide rods 220. The two rubber plates 230 are in contact with each other, and the top of the sleeve 240 is in contact with the bottom of the guide rod 220 near the bottom of the heat insulation channel 110.

[0035] Furthermore, multiple T-shaped tubes 120 are arranged at equal intervals in a row, with two connecting tubes 130 on each T-shaped tube 120 arranged vertically. The T-shaped tubes 120 are connected to the interior of the thin-walled rollers 170 through the connecting tubes 130. This layout design allows for the horizontal arrangement of two rows of thin-walled rollers 170, providing conditions for uniform heating of the corrugated cardboard. On the other hand, the interconnection between the T-shaped tubes 120, the connecting tubes 130, and the thin-walled rollers 170 allows the thin-walled rollers 170 to have the conditions to increase their temperature, ensuring that the heating of the corrugated board can be carried out smoothly.

[0036] Furthermore, the two hot air chambers 210 on the T-shaped rod 140 are laterally symmetrical about the horizontal center plane of the T-shaped rod 140. The interior of the thin-walled roller 170 is connected to the interior of the heat insulation channel 110 through the hot air chambers 210. This structural design allows the hot air inside the thin-walled roller 170 to flow into the interior of the heat insulation channel 110 through the hot air chambers 210, providing conditions for collecting waste heat and reducing energy consumption.

[0037] Furthermore, handles 500 are installed on the outer sides of the two rubber plates 230 near the top of the heat insulation channel 110. The handles 500 facilitate lifting the upper rubber plate 230 and help to pass the corrugated cardboard between the two rubber plates 230.

[0038] Example 2:

[0039] Combination Figure 1 and Figure 5As shown, based on Embodiment 1, the heat insulation channel 110 is provided with an adjusting mechanism 300. The adjusting mechanism 300 includes two connecting plates 310 connected between multiple connecting pipes 130 and a bidirectional electric push rod 320 connected between the two connecting plates 310. The two connecting plates 310 are arranged horizontally and parallel to each other, and the two bidirectional electric push rods 320 are connected in series. By controlling the distance between the two connecting plates 310 through the two bidirectional electric push rods 320, the distance between the two rows of thin-walled rollers 170 can be adjusted, providing conditions for heating corrugated cardboard of any thickness and improving the applicability of this device.

[0040] Furthermore, a reinforcing plate 600 is sleeved on the outer side of the cylinder body of the bidirectional electric push rod 320. The reinforcing plate 600 is fixedly connected to the front side wall of the inner cavity of the heat insulation channel 110. The reinforcing plate 600 can fix the bidirectional electric push rod 320 and make its operation more stable.

[0041] Example 3:

[0042] Combination Figure 1 As shown, in the above embodiment, two supports 400 are installed at the bottom of the heat insulation channel 110. The two supports 400 are vertically symmetrical about the vertical center plane of the heat insulation channel 110, and the bottoms of the two supports 400 are located on the same horizontal plane. By setting the supports 400, the heat insulation channel 110 can be lifted, providing conditions for adjusting the height of the two rubber plates 230 that are in contact with each other.

[0043] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the T-shaped tube 120 is connected to an external heat source device (hot air blower). Then, according to the thickness of the corrugated cardboard being conveyed, the movable ends of the two bidirectional electric push rods 320 are controlled to retract, ensuring that the two rows of thin-walled rollers 170 can be pressed tightly against the top and bottom of the corrugated cardboard, providing conditions for heating the corrugated cardboard. After that, the sleeve plate 240 is rotated, and the two rubber plates 230 on the top of the sleeve plate 240 are pushed up, so that the contact surfaces of the two rubber plates 230 are flush with the top of the lower row of thin-walled rollers 170. Then, the rollers near the top of the heat insulation channel 110 are raised. Rubber sheet 230 allows corrugated cardboard to pass through heat insulation channel 110. Then, the external heat source equipment is activated, and hot air enters the interior of thin-walled roller 170 through T-shaped pipe 120 and connecting pipe 130. Thin-walled roller 170 heats up rapidly, and then multiple thin-walled rollers 170 work together to heat the top and bottom of the corrugated cardboard. During this process, hot air enters the interior of heat insulation channel 110 through hot air chamber 210. In addition, both ends of heat insulation channel 110 are blocked by rubber sheet 230, which reduces the rate of heat loss in heat insulation channel 110, realizes the collection of residual heat, improves the preheating speed of this device, and reduces energy consumption.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
