Description

Technical Field

[0001] This utility model relates to the field of paraffin wax production, specifically a roller-type paraffin wax demolding device. Background Art

[0002] A paraffin molding machine is a piece of equipment for producing paraffin wax. Paraffin wax molding is an important part of the production process of paraffin wax products, and demolding is a key step after molding. Because paraffin wax has a certain degree of stickiness in the solidified state, it is often impossible to guarantee complete demolding by its own weight. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a roller-type paraffin wax demolding device.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A roller-type paraffin wax demolding device includes two guide frames arranged in parallel. Several pairs of connecting rods are arranged on the top of each guide frame, with two rods per pair. Between each pair of connecting rods are several wax discs. Two connecting rods are fixedly connected to the front and rear outer walls of the open ends of the wax discs, respectively. A chain is fixedly connected between each pair of connecting rods. Rollers are rotatably connected to both ends of the connecting rods. The rollers are located on the upper parts of the two guide frames and slide against them. Support frames are fixedly connected to the left and right side walls of the guide frames. A gantry is fixedly connected between the top ends of the two support frames. A middle rod is fixedly connected between the middle sections of opposite side walls of the gantry. Several hangers are fixedly connected to the bottom of the gantry, and the hangers are located above the wax disc. The bottom of the hanger has a pressure rod, the middle of which is rotatably connected to the bottom of the hanger. The front end of the pressure rod is inclined downward and is fixedly connected to the upper end of the connecting frame. The connecting frame is U-shaped, with the upper end connected and the lower end open. The inner side of the connecting frame is rotatably connected to the pressure roller, and the bottom of the pressure roller is lower than the upper surface of the wax disc. Several fixing plates are fixedly connected to the top of the gantry, and the fixing plates are located above the rear end of the pressure rod. The rear end of the fixing plate protrudes backward from the gantry. There is a tension spring between the rear end of the fixing plate and the rear end of the pressure rod. The top and bottom ends of the tension spring are rotatably connected to the rear end of the fixing plate and the rear end of the pressure rod, respectively.

[0006] The top of the guide frame is provided with a groove, and the roller is inside the groove, with the roller slidingly engaging with the groove.

[0007] There are undemolded wax plates in the wax disc behind the pressure roller.

[0008] The beneficial effects of this utility model are:

[0009] The wax tray is normally flat. The pressure roller can create a depression at the bottom of the wax tray, allowing the wax plate inside the inverted wax tray to detach from the tray. Through the combination of the rolling of the pressure roller and the tension of the spring, the adhesive bond between the wax plate and the wax tray can be broken efficiently, achieving rapid demolding.

[0016] like Figure 1-5 As shown: This utility model is a part of the existing paraffin wax molding machine, and is designed to solve the problem of paraffin wax demolding in paraffin wax molding machines. The paraffin wax molding machine includes two guide frames 1, which are arranged in parallel. Several pairs of connecting rods 3 are provided on the top of the guide frames 1. There are two connecting rods 3 in each pair, and several wax discs 2 are provided between each pair of connecting rods 3. The front and rear outer walls of the open end of the wax discs 2 are respectively fixedly connected to two connecting rods 3. A chain 15 is fixedly connected between each pair of connecting rods 3. Rollers 4 are rotatably connected to both ends of the connecting rods 3. The rollers 4 on both sides are located on the upper part of the two guide frames 1, and the rollers 4 are slidably engaged with the guide frames 1. Support frames 5 are fixedly connected to the left and right side walls of the guide frames 1.

[0017] A roller-type paraffin wax demolding device includes a support frame 5 and a gantry 6. The gantry 6 is fixedly connected between the top ends of the two support frames 5. An intermediate rod 7 is fixedly connected between the middle parts of the opposite side walls of the gantry 6. Several hangers 8 are fixedly connected to the bottom of the intermediate rod 7. The hangers 8 are respectively located above the wax tray 2. The bottom of the hanger 8 has a pressure rod 9. The middle part of the pressure rod 9 is rotatably connected to the bottom of the hanger 8. The front end of the pressure rod 9 is inclined downward and fixedly connected to the upper end of the connecting frame 10. The connecting frame 10 is U-shaped. The frame 6 is shaped such that the upper end of the connecting frame 10 is connected to the frame 6, the lower end of the connecting frame 10 is open, the inner side of the connecting frame 10 is rotatably connected to the pressure roller 11, the bottom of the pressure roller 11 is lower than the upper surface of the wax plate 2, and the top of the frame 6 is fixedly connected to several fixing plates 12. The fixing plates 12 are respectively located above the rear end of the pressure rod 9, and the rear end of the fixing plates 12 protrudes backward from the frame 6. There is a tension spring 13 between the rear end of the fixing plates 12 and the rear end of the pressure rod 9. The top and bottom ends of the tension spring 13 are rotatably connected to the rear end of the fixing plates 12 and the rear end of the pressure rod 9, respectively.

[0018] The top of the guide frame 1 is provided with a groove 16, and the roller 4 is in the groove 16. The roller 4 and the groove 16 are slidably engaged.

[0019] The wax disc 2 on the rear side of the pressure roller 11 contains an undemolded wax plate 14.

[0020] The pressure roller 11 is located in front of the wax disc 2, and its middle part is lower than the upper surface of the wax disc 2.

[0021] The pressure rod 9 is connected to the fixed plate 12 via the tension spring 13, which is in an unstretched state.

[0022] When the wax disc 2 moves along the guide frame 1 to below the pressure roller 11, it lifts up the pressure roller 11. After the pressure roller 11 contacts the bottom surface of the wax disc 2, since the initial position of the pressure roller 11 is lower than the bottom surface of the wax disc 2, and the wax plate 14 has a certain degree of stickiness in the solidified state, the pressure roller 11 will apply a downward pressure to the wax disc 2.

[0023] At the same time, the tension spring 13 begins to stretch, providing a backward pulling force to the pressure rod 9. This pulling force is transmitted to the wax plate 2 through the pressure rod 9, causing the bottom surface of the wax plate 2 to bulge slightly downward under the tension of the tension spring 13. The bottom surface of the wax plate 2 has a certain elasticity and can rebound under pressure.

[0024] The slight protrusion of the wax disc 2, combined with the rolling of the pressure roller 11, breaks the adhesive connection between the wax plate 14 and the wax disc 2, allowing the wax plate 14 to fall off smoothly.

[0025] After demolding, the rear end of the pressure rod 9 is pulled up by the tension spring 13 and returned to the initial position.
