[0027] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In order to solve the problems existing in the prior art, an embodiment of the present application provides a sulfuric acid paper flattening device.

[0029] like Figure 1 As shown, a sulfuric acid paper flattening device comprises an air supply device 1, a connecting pipe 2, a mounting frame 3, an air jet element 4 and a temperature control element 7; the air jet element 4 is mounted above the strip box conveying line through the mounting frame 3, and is used to flatten the sulfuric acid paper, and the air inlet of the air jet element 4 is connected to the air outlet of the air supply device 1 through the connecting pipe 2, the air outlet of the air jet element 4 faces the discharge direction of the strip box conveying, and forms an angle with the strip box conveying line; the air supply device 1 is used to provide pressurized gas; the temperature control element 7 is used to change the temperature of the gas ejected by the air jet element 4.

[0030] The invention discloses a paper flattening device. The paper flattening device uses a gas supply device as a jet element to supply gas to flatten the paper on a hard box being transported. The temperature of the gas ejected by the jet element is controlled by a temperature control element. The hardness of the paper flattening device can be reduced, thereby improving the flattening effect, improving the production quality, and ensuring the normal progress of subsequent work.

[0031] In some preferred embodiments, the temperature control element 7 is a semiconductor refrigeration sheet, which is at least used to heat the gas ejected from the jet element 4; thereby, the softness of the sulfuric acid paper is increased by increasing the temperature, thereby facilitating flattening; specifically, the increased temperature is determined according to the working conditions.

[0032] In some preferred embodiments, the angle between the outlet of the jet element 4 and the strip box conveying line is A, 35°≤A≤65°; based on setting the outlet of the jet element 4 to have an angle with the strip box conveying line greater than or equal to 35° and less than or equal to 65°, in conjunction with the temperature control element 7 controlling the temperature of the ejected gas, a better blowing effect can be ensured; specifically, heating can be performed first and then cooling, so as to soften the sulfuric acid paper by heating, and after blowing, the sulfuric acid paper can be hardened by cooling with cold air to improve the blowing effect.

[0033] In some preferred embodiments, the jet element 4 is a pressure-regulating pneumatic connector, such as model PLS-6-01; specifically, the air inlet side (the side with the vent hole) of the pressure-regulating pneumatic connector is used as the air outlet side, and the other side is used as the side connected to the connecting pipe 2.

[0034] In some preferred embodiments, the jet element 4 includes a first jet element 41 and a second jet element 42; the first jet element 41 and the second jet element 42 are respectively installed on the mounting frame 3, and the first jet element 41 is higher than the second jet element 42 and is closer to the discharge side of the strip box conveyor, the angle between the air outlet of the first jet element 41 and the strip box conveyor line is 35°-45°; the angle between the air outlet of the second jet element 42 and the strip box conveyor line is 55°-65°; based on the first jet element 41 and the second jet element 42 jointly blowing the sulfuric acid paper, the flattening effect is better; and in combination with the limitation, the first jet element 41 is used to blow air on the sulfuric acid paper close to the conveyor The part on the discharge side is blown flat, and the part close to the feed side is blown flat by the second jet element 42, and the air outlet direction of the second jet element 42 is closer to perpendicular to the sulfuric acid paper. Therefore, a certain downward pressure is formed on the sulfuric acid paper, which can avoid the sulfuric acid paper shaking during the flattening process and affect the flattening effect. At this time, a better flattening effect is achieved under the first jet element 41, and based on the fact that the air outlet direction of the first jet element 41 is set to 35°-45°, the wind blown out during the box cover packaging process can still blow into the gap between the box cover and the sulfuric acid paper. In the process of closing the box cover, the blowing wind is redirected to produce a downward pressure on the sulfuric acid paper, further ensuring that the sulfuric acid paper is flat when the box cover is closed.

[0035] Preferably, if Figure 1 As shown, the temperature control element 7 is a semiconductor refrigeration chip; the hot end of the semiconductor refrigeration chip is located in a connecting pipe connected to the first jet element 41, and the cold end is located in a connecting pipe connected to the second jet element 42; thus, the first jet element 41 blows out hot air, and the second jet element 42 blows out cold air. Under the action of the hot air, the part of the sulfuric acid paper that is closer to the discharge side of the conveyor and is more easily bent becomes soft due to the heat, and is easier to blow flat under the action of the blowing air, while under the action of the cold air of the second jet element 42, the sulfuric acid paper becomes hard, and the shaping effect is better.

[0036] Preferably, a position sensor is also included, which is used to detect the position of the hard box, so that when the hard box moves to the intersection of the air outlet of the first jet element 41 and the moving line of the hard box, the first jet element 41 and the second jet element 42 are started to spray. At this time, the first jet element 41 blows the sulfuric acid paper close to the discharge side, and the second jet element 42 blows the sulfuric acid paper close to the feed side; specifically, a regulating valve 6 can be set on the connecting pipe 2 to adjust the gas outlet of the jet element 4 and whether to supply air to the first jet element 41 and the second jet element 42; the specific type of the position sensor can be selected from existing devices without limitation.

[0037] Preferably, two first jet elements 41 and two second jet elements 42 are arranged side by side, respectively, so as to increase the width of the air outlet and thus increase the flattening area.

[0038] In some preferred embodiments, Figure 1 and Figure 2 As shown, the mounting frame 3 includes a first mounting plate 31, a second mounting plate 32 and a third mounting plate 33; the first mounting plate 31 is used for external installation and fixation; the second mounting plate 32 and the third mounting plate 33 are respectively vertically connected to the first mounting plate 31, and the angle is 160°; the first jet element 41 is installed on the second mounting plate 32; the second jet element 42 is installed on the third mounting plate 33; based on the first jet element 41 and the second jet element 42 are respectively arranged on the second mounting plate 32 and the third mounting plate 33 at an angle, the difference in the outlet direction between the two can be ensured, thereby ensuring the stability of the size of the blowing plane formed by the two, thereby ensuring the flattening effect.

[0039] Preferably, if Figure 3 As shown, the second mounting plate 32 has a second long mounting hole 321 for mounting the first jet element 41, and the air outlet of the first jet element 41 is oriented perpendicular to the second mounting plate 32, thereby, the horizontal position of the first jet element 41 can be adjusted or the number of the first jet elements 41 can be increased; for example, two first jet elements 41 are arranged side by side, and the center distance between the air outlets of the two first jet elements 41 is 30 mm; and / or, the third mounting plate 33 has a third long mounting hole 331 for mounting the second jet element 42; the air outlet of the second jet element 42 is oriented perpendicular to the third mounting plate 33, thereby, the horizontal position of the second jet element 42 can be adjusted or the number of the second jet elements 42 can be increased, for example, two second jet elements 42 are arranged side by side, and the center distance between the air outlets of the two second jet elements 42 is 30 mm.

[0040] Preferably, the second mounting plate 32 and the third mounting plate 33 are formed by bending a flat plate.

[0041] Preferably, the first mounting plate 31 is disposed vertically and parallel to the conveying direction of the strip box.

[0042] Preferably, the air outlets of the first jet element 41 and the second jet element 42 are spaced 45 mm apart in the direction of the strip box conveying line and 29 mm apart vertically; at this time, a continuous blowing plane is formed to improve the blowing effect.

[0043] In some preferred embodiments, Figure 2 and Figure 4 As shown, the first mounting plate 31 has a first mounting hole 311 and an adjustment hole 312; the first mounting hole 311 is a round hole, which is used to pass a bolt 36 to fix the position of the first mounting plate 31; the adjustment hole 312 is an arc-shaped long hole, which is used to cooperate with the limiter 34 to limit the rotation range of the first mounting plate 31; based on this, the direction of the air outlet of the jet element 4 is adjusted to adapt to different blowing conditions.

[0044] Preferably, the limiting member 34 is a limiting bolt, one end of which passes through the adjustment hole 312 and is fixed, for example, on a bracket of the hard strip packaging equipment.

[0045] In some preferred embodiments, the central angle corresponding to the adjustment hole 312 is 50°.

[0046] In some preferred embodiments, the first mounting plate 31 can rotate upward under the action of the first jet element 41, that is, the position of the first mounting plate 31 is not fixed, but can rotate around the bolt 36. At this time, the connecting pipe connecting the first jet element 41 and the second jet element 42 is a flexible pipe; based on this, when the air volume of the first jet element 41 is too large, the first mounting plate 31 can be driven to rotate, so that the first jet element 41 is separated from the conveying line of the sulfuric acid paper, and the first jet element 41 no longer blows on the sulfuric acid paper, so as to avoid the sulfuric acid paper shaking caused by its excessive air volume, which affects the flattening effect, and based on the rotation of the first mounting plate 31, the second jet element 42 is driven to rotate at the same time, so as to blow the sulfuric acid paper from the near inlet. Continuously blow from one side of the material end to one side of the discharge end to improve the flattening effect; at this time, the regulating valve 6 can be used to adjust the air output of the first jet element 41, so that the air output of the first jet element 41 gradually increases, and the flattening effect on the sulfuric acid paper is improved during the increase, and when the critical air volume value is exceeded, the first jet element 41 drives the first mounting plate 31 to rotate to avoid excessive air volume affecting the flattening effect. At this time, the second jet element 42 blows continuously on the plane of the sulfuric acid paper again, which can improve the flattening effect, that is, it is equivalent to achieving the first jet element 41 and the second jet element 42 positioning and stable flattening and the second jet element 42 rotating and continuously flattening twice, and the flattening effect is better.

[0047] Preferably, a torsion spring 35 is further included, and the first mounting plate 31 is reset after being rotated by the torsion spring.

[0048] Preferably, the temperature control element 7 is a semiconductor refrigeration chip; the hot end of the semiconductor refrigeration chip is located in a connecting tube connected to the first jet element 41, and the cold end is located in a connecting tube connected to the second jet element 42; when the air output of the first jet element 41 increases and drives the first mounting plate 31 to rotate, the second jet element 42 blows out cold air to cool and shape all parts of the sulfuric acid paper, which can maintain the flattening effect, thereby reducing the deformation of the sulfuric acid paper during the process of closing the box cover.

[0049] In some preferred embodiments, a filter 5 is further included; the filter 5 is arranged between the gas supply device 1 and the jet element 4, and is used to filter the gas output by the gas supply device 1, such as being selected as an air filter, and is used to filter impurities such as particles and water in the gas.

[0050] In some preferred embodiments, a regulating valve 6 is further included; the regulating valve 6 is arranged on the connecting pipe 2 and is used to adjust the gas output of the jet element 4.

[0051] In some preferred embodiments, the connecting pipe 2 includes a straight pipe 21 and a three-way pipe 22, which are connected to form the connecting pipe 2, and based on the provision of the three-way pipe 22, an external connecting port can be formed to connect with other gas-using equipment in the outside world.
