Description

Technical Field

[0001] The utility model relates to the technical field of pulp tableware production, in particular to an anti-adhesion drying machine. Background Art

[0002] Pulp tableware is made by using a mold to vacuum-adsorb paper pulp, forming it, and drying it. It is then further processed to make tableware that can replace metal and plastic for people to use. In the drying step, since the material is pulp, it is relatively soft when the humidity is too high, and the wet blank tends to collapse. Usually, a hot press is used to support it with a mold that matches the shape of the wet blank to heat and dry it.

[0003] However, some of the current hot press dryers for pulp tableware, in actual use, require the use of molds or similar grooves to support the wet blanks for shaping, and the actual contact area with the pulp tableware is larger. Since the pulp tableware contains moisture, the pulp tableware will stick to the mold when it is in contact with the mold for a long time, which will hinder the demolding and material removal work after drying. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. During the drying process, the rotating side wall is rotated to make the rotating side wall independent of the side wall of the cutlery shaping groove, and the rotating side wall is given the ability to rotate through the special-shaped bearing, so that a relative state of dynamic-static difference is formed between the rotating side wall in contact with the wet cutlery blank and the side wall of the cutlery shaping groove, so that part of the side surface of the wet cutlery blank is in contact with the side surface of the cutlery shaping groove, and part of it is in contact with the rotating side wall. The friction between the rotating side wall and the contact surface of the wet cutlery blank gives the wet cutlery blank an effect of rotating with the rotating side wall. At the same time, the friction between the contact surface of the cutlery shaping groove and the wet cutlery blank hinders the rotational motion of the wet cutlery blank, reduces the rotation speed of the wet cutlery blank, and makes a speed difference between the rotation speed of the wet cutlery blank and the rotating side wall, so as to avoid the wet cutlery blank and the side wall of the cutlery shaping groove from sticking to each other, and at the same time, avoid the wet cutlery blank and the rotating side wall from sticking to each other through the speed difference.

[0015] 2. When the hot pressing plate is lowered, the supporting feet form a certain gap between the base and the hot pressing plate, and the limiting support bars limit the falling degree of each heating module to avoid direct contact between the heating module and the wet blank. The gap between the limiting support bars facilitates the escape of water vapor generated during drying. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 6 In an embodiment of the utility model, an anti-adhesion drying machine includes a hot pressing device 1, a drying seat 2 is fixedly installed in the hot pressing device 1, a hot pressing structure 3 is fixedly installed in the hot pressing device 1, the drying seat 2 includes a base 201, a tableware shaping groove 202 is opened on the upper surface of the base 201, a rotating side wall 203 is rotatably embedded in the groove wall of the tableware shaping groove 202, and the outer surface of the rotating side wall 203 is fixedly connected to the inner ring of the special-shaped bearing 204.

[0025] Specifically, the wet pulp tableware blanks to be dried are placed in the tableware shaping groove 202, and the tableware shaping groove 202 temporarily supports and shapes the wet blanks to prevent the wet blanks from being too high in moisture content and the tableware from being too soft and collapsing before drying. The hot pressing device 1 drives the hot pressing structure 3 to press down to dry the wet blanks in each tableware shaping groove 202. During the drying process, the rotating side wall 203 is rotated to make the rotating side wall 203 independent of the side wall of the tableware shaping groove 202, and the rotating side wall 203 is given the ability to rotate through the special-shaped bearing 204, so that the rotating side wall 203 in contact with the wet tableware blanks and the tableware shaping groove 202 are in contact with each other. 02 forms a relative state of dynamic-static difference between the side walls, so that part of the side surface of the wet blank contacts with the side surface of the cutlery shaping groove 202, and part of it contacts with the rotating side wall 203. The friction between the rotating side wall 203 and the contact surface of the wet blank gives the wet blank an effect of following the rotation of the rotating side wall 203. At the same time, the friction between the contact surface of the cutlery shaping groove 202 and the wet blank hinders the rotational motion of the wet blank, reduces the rotation speed of the wet blank, and creates a speed difference between the rotation speed of the wet blank and the rotating side wall 203, thereby avoiding the wet blank and the side wall of the cutlery shaping groove 202 from sticking to each other, and avoiding the wet blank and the rotating side wall 203 from sticking to each other through the speed difference.

[0026] Embodiment 1

[0027] like Figure 1-2 As shown, in this embodiment, the hot pressing equipment 1 includes an equipment main body 101, and support guide rods 102 are fixedly installed at the four corners of the upper surface of the equipment main body 101. The upper end of the support guide rod 102 is fixedly connected to the four corners of the bottom side of the top plate 103. An electric push rod 104 is fixedly installed in the middle of the top plate 103, and the output end of the electric push rod 104 is fixedly connected to a pressure plate 105. The four corners of the pressure plate 105 are slidably connected to the side surface of the support guide rod 102; the hot pressing plate 301 is fixedly installed on the bottom side surface of the pressure plate 105.

[0028] In this embodiment, the lifting and lowering of the pressing plate 105 is controlled by the electric push rod 104 , thereby controlling the hot pressing structure 3 to place the wet blank close to the drying seat 2 .

[0029] like Figure 3-4As shown, in the present embodiment, there are several cutlery shaping grooves 202, and an outer toothed ring 205 is fixedly sleeved on the lower edge of the outer surface of the rotating side wall 203; there are several groups of outer toothed rings 205, and each group has two, and a gear 206 is meshed between each group of outer toothed rings 205, and the bevel gear fixedly installed on the bottom side of the gear 206 is meshed with the bevel gear fixedly installed on the side surface of the transmission rod 207, and the number of the transmission rod 207 is three, and the bevel gear fixedly installed at one end of the transmission rod 207 is meshed with the bevel gear fixedly installed on the side surface of the linkage rod 208, and one end of the linkage rod 208 is fixedly connected to the output end of the driving motor 209, the gear 206, the transmission rod 207 and the linkage rod 208 are rotatably installed inside the base 201, and the driving motor 209 is fixedly buried and installed inside the base 201; the base 201 is fixedly installed in the middle of the upper surface of the device host 101.

[0030] In specific implementation, the driving motor 209 is a slow motor. The driving motor 209 rotates the linkage rod 208, and the transmission rods 207 are rotated through the transmission of the bevel gears, and then the gears 206 are rotated through the bevel gears, and then the groups of outer gear rings 205 are rubbed to rotate the rotating side walls 203. Through a single power source, each rotating side wall 203 is synchronously controlled.

[0031] Embodiment 2

[0032] On the basis of Example 1, in order to compensate for the situation in Example 1 where the pressure plate 105 pushes the hot pressing plate 301 to make the heating module 303 inserted into the tableware shaping groove 202 for heating and drying, the evaporated water vapor is difficult to be discharged due to the closure of the base 201 and the hot pressing plate 301.

[0033] like Figure 5-6 As shown, in this embodiment, the hot pressing structure 3 includes a hot pressing plate 301, and support legs 302 are fixedly installed at the four corners of the bottom side of the hot pressing plate 301. A heating module 303 is fixedly installed on the bottom side of the hot pressing plate 301. There are several heating modules 303, and several limiting support bars 304 are fixedly installed at the root edge of the heating module 303 at equal angles in a ring shape.

[0034] In specific implementation, when the hot pressing plate 301 is lowered, a certain gap is formed between the base 201 and the hot pressing plate 301 by the supporting legs 302, and then the limiting support bars 304 limit the falling degree of each heating module 303 to avoid direct contact between the heating modules 303 and the wet blanks. The gaps between the limiting support bars 304 facilitate the escape of water vapor generated during drying.
