DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0022] like Figure 1-6As shown, an embodiment of the present invention proposes a pressing device for packaging film production. The pressing device designed in this scheme can optimize the contact between the pressing rollers from linear contact to surface contact when performing the pressing operation on the packaging film, thereby increasing the pressing area of ​​the packaging film and improving the pressing effect. The device comprises a base 1 and a connecting frame 3. The base 1 and the connecting frame 3 are fixedly connected. A transmission member 4 is connected between the base 1 and the connecting frame 3. A spacing adjustment member 5 is connected to the connecting frame 3. A pressing member 2 is provided on the base 1 and the spacing adjustment member 5. A tensioning member 6 is symmetrically slidably connected to the connecting frame 3. The device is electrically connected to an external control device through a conductive line. Through the external control device Control the operating state of the device. When compressing the packaging film, the packaging film is placed between the two pressing members 2, and then the spacing adjustment member 5 is adjusted according to the thickness of the packaging film to control the spacing between the two pressing members 2. The U-shaped frame 501 is raised and lowered by rotating the screw 503 to control the spacing between the two pressing members 2 so that the two pressing members 2 are in tight contact. Since the outer wall of the pressing roller 201 is provided with a silicone tube 202, when the two pressing rollers 201 are in tight contact, the silicone tube 202 is deformed by pressure. At this time, the contact area of ​​the two silicone tubes 202 changes from linear contact to surface contact. At this time, the packaging film is placed between the two silicone tubes 202, so that the pressing member 2 presses the packaging film. The tightening area is increased and the pressing effect is improved. The tensioning members 6 symmetrically arranged on both sides of the connecting frame 3 can press down the upper side of the packaging film, so that the packaging film is conducted in a W-shaped manner when it is transmitted on the device, so that the lower side of the packaging film is tightly attached to the pressing member 2 located below. The two tensioning members 6 adjust the tension of the packaging film to avoid wrinkles in the packaging film during the pressing operation, which affects the pressing effect. The operation of the motor 104 rotates the first bevel gear 105 and the transmission member 4, and the first bevel gear 105 meshes with the second bevel gear 204 located below, so that the pressing member 2 located below rotates between the two rotating seats 102, and the third bevel gear 505 is transmission-connected to the sliding groove 40 2, so when the transmission rod 401 rotates, the third bevel gear 505 can mesh with the second bevel gear 204 above, so that the clamping piece 2 located above rotates. Since the two clamping pieces 2 are driven by the same motor 104, and the rotation directions of the two clamping pieces 2 are relative or opposite, and the packaging film needs to be transmitted, the rotation directions of the two clamping pieces 2 need to rotate relative to each other. Since the inner wall of the third bevel gear 505 is fixedly connected with a protrusion, while keeping the third bevel gear 505 rotationally connected to the transmission rod 401, the third bevel gear 505 can follow the rise and fall of the U-shaped frame 501 and slide and adjust on the transmission rod 401 at the sliding groove 402 to meet the adjustment requirements.
