Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to a heating device for a large-capacity injection welding cover heating plate. Background Art

[0002] The cap welding process involves a filled infusion bottle passing through a transition dial, where the lower capping fingers grip the bottle and the upper capping fingers grip the combined cap. The bottle then enters the cap welding heating device, where the bottle mouth and the combined cap are heated during transport. Finally, the cap welding cam presses and welds the bottle mouth and combined cap together. The finished capped product is then sent to the next process.

[0003] like Figure 1 In the conventional cap welding process, the first heating plate 4 is connected to the copper plate 3 via a power supply to control the heating temperature. The first heating plate 4 is a single integral heating plate. In the cap welding process, unstable heat output is prone to occur during the heating process. That is, when the heating plate reaches the set temperature, it is difficult to maintain a constant temperature for a long time. After a certain period of time, the temperature of the heating plate will fluctuate. When the temperature is high, the infusion bottle may be overheated and the cap may be over-burned. When the temperature is low, the infusion bottle may be poorly welded. In addition, the conventional heating plate is a one-piece structure. If heated for a long time, the heating plate may deform. These problems will cause certain quality risks to the product. Utility Model Content

[0004] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a large-capacity injection welding cover heating plate heating device, so as to solve the problem in the prior art that welding is carried out for a long time through the heating plate, and when the temperature of the heating plate fluctuates, it will affect the welding quality, and the device needs to be shut down to cool down, affecting the production progress.

[0005] A large-capacity injection welding cover heating plate heating device includes a power supply connecting copper plate and a second heating plate; the second heating plate includes a plurality of heating single plates arranged at intervals; the power supply connecting copper plate is electrically connected to the heating single plates, and is used to control the heating single plates to heat them separately.

[0006] Furthermore, the heating device includes a cooling water tank; the cooling water tank is arranged horizontally, and the top and bottom surfaces of the cooling water tank are respectively provided with first insulating plates; the second heating plate is provided on a side of the first insulating plate away from the cooling water tank.

[0007] Furthermore, a second insulating plate is provided on a side of the second heating plate facing away from the first insulating plate.

[0008] Furthermore, a cover plate is provided on a side of the second insulating plate facing away from the second insulating plate, and the cover plates on the upper side and the lower side of the cooling water tank are connected by bolts.

[0009] Furthermore, a connecting plate is provided on a side of the second heating plate facing away from the first insulating plate; and two adjacent heating plates are connected via the connecting plate.

[0010] Furthermore, the connecting plates on the upper and lower sides of the cooling water tank are connected by bolts.

[0011] Furthermore, the heating plate is provided with holes for installing bolts.

[0012] Beneficial effect: The utility model replaces a single integral heating plate with several heating plates arranged at intervals in segments, and heats the several heating plates separately through a power supply connected to a copper plate, thereby heating the heating plates in batches. After a batch of heating plates has worked for a period of time, the heating is stopped before temperature fluctuations may occur, and another batch of heating plates is heated. The welding is completed by alternating heating of multiple batches of heating plates, which reasonably avoids temperature fluctuations and prevents device shutdown.
