DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0024] The embodiment of the utility model provides a film splicing device, which belongs to the field of food packaging. The film splicing device is used to assist in splicing two sections of plastic film. By using the above-mentioned film splicing device, the plastic film can be stretched before splicing to avoid problems such as plastic film dislocation and plastic film wrinkles caused by the film splicing operation.
[0025] In some preferred embodiments, the film connection device includes a mounting seat 100, a first clamping assembly 200 and a second clamping assembly 300, wherein the mounting seat 100 is provided with a strip groove 110 connecting the front and back sides thereof. The first clamping assembly 200 is installed on one side of the strip groove 110, and the mounting seat 100 is provided with a strip groove 110 connecting the front and back sides thereof. The first clamping assembly 200 includes a first film inlet clamping member 210 and a first film outlet clamping member 220 for clamping the plastic film, wherein the first film inlet clamping member 210 is installed on the front side of the mounting seat 100, and the first film outlet clamping member 220 is installed on the back side of the mounting seat 100. The second clamping assembly 300 is installed on the other side of the strip groove 110, and the second clamping assembly 300 includes a second film inlet clamp 310 and a second film outlet clamp 320 for clamping the plastic film. The second film inlet clamp 310 is installed on the front side of the mounting seat 100, and the second film outlet clamp 320 is installed on the back side of the mounting seat 100.
[0026] In the above embodiment, the end of the first section of plastic film is passed through the strip groove 110 from the front of the mounting seat 100 and wound around the back of the mounting seat 100, and then the first section of plastic film is clamped by the first film inlet clamp 210 and the first film outlet clamp 220, thereby tensioning the first section of plastic film. The end of the second section of plastic film is also passed through the strip groove 110 from the front of the mounting seat 100 and wound around the back of the mounting seat 100, and then the second section of plastic film is clamped by the second film inlet clamp 310 and the second film outlet clamp 320, thereby tensioning the second section of plastic film. The first section of plastic film and the second section of plastic film are connected together from the front of the mounting seat 100 by using adhesive tape, and then the ends of the first section of plastic film and the second section of plastic film are cut off from the back of the mounting seat 100, thereby completing the connection operation of the plastic film. By using the film joining device provided by the utility model, the plastic film can be tensioned before film joining, thereby avoiding problems such as plastic film dislocation and plastic film wrinkles caused by the film joining operation.
[0027] In some preferred embodiments, the first film inlet clamp 210, the first film outlet clamp 220, the second film inlet clamp 310 and the second film outlet clamp 320 all include a plastic film clamp 211, which has a first state of clamping the plastic film and a second state of allowing the plastic film to pass through.
[0028] It is understandable that the structures of the first film inlet clamp 210 , the first film outlet clamp 220 , the second film inlet clamp 310 and the second film outlet clamp 320 may be completely the same, and they only differ in placement positions.
[0029] Any implementation of the plastic film clamp 211 that can clamp and fix the plastic film is feasible. In some preferred embodiments, the plastic film clamp 211 includes a connecting rod 2111, a pressure plate 2112 and a handle 2113. One end of the connecting rod 2111 is hinged to the mounting seat 100, and the other end is hinged to the middle of the pressure plate 2112. The handle 2113 is connected to the pressure plate 2112 to drive the pressure plate 2112 to move closer to or away from the plastic film. When the plastic film clamp 2111 is in a first state, the pressure plate 2112 and the mounting seat 100 clamp the plastic film. When the plastic film clamp 2111 is in a second state, the pressure plate 2112 is away from the plastic film.
[0030] In the above embodiment, the handle 2113 is used to drive the pressing plate 2112 to move, so that the pressing plate 2112 presses the plastic film, so that the pressing plate 2112 and the mounting seat 100 clamp and fix the plastic film. The pressing plate 2112 is moved away from the plastic film, so that the plastic film can pass through the plastic film clamp 211 smoothly.
[0031] On the basis of the above embodiments, in some preferred embodiments, one end of the handle 2113 is hinged to the mounting seat 100, the middle part of the handle 2113 is hinged to the pressing plate 2112, and when the plastic film clamp 211 is in the first state, the handle 2113 is perpendicular to the pressing plate 2112. When the plastic film clamp 211 is in the first state, when the pressing plate 2112 has a tendency to move away from the plastic film, since the handle 2113 is perpendicular to the pressing plate 2112, the pressing plate 2112 cannot exert a torque to rotate the handle 2113, so that the handle 2113 achieves a self-locking effect, and the pressing plate 2112 can stably clamp the plastic film.
[0032] In some preferred embodiments, the pressing plate 2112 has a magnetic attraction portion 21121, and the magnetic attraction portion 21121 has a magnetic force that can attract the mounting seat 100. Therefore, under the magnetic force of the magnetic attraction portion 21121, the plastic film clip 211 is more stably in the first state.
[0033] In some preferred embodiments, a rubber pad is attached to the side of the pressing plate 2112 close to the plastic film. On the one hand, the rubber pad has a certain elasticity, which can prevent the pressing plate 2112 from crushing the plastic film. On the other hand, the rubber pad has a large friction coefficient, which can increase the friction between the pressing plate 2112 and the plastic film and prevent the plastic film from slipping.
[0034] In some preferred embodiments, two cutting grooves 120 are respectively formed on the back of the mounting seat 100, close to the first film-discharging clamp 220 and the second film-discharging clamp 320, and the cutting grooves 120 are parallel to the strip groove 110. The operator can use a cutting knife to cut the plastic film along the strip groove 110, thereby efficiently removing the end of the plastic film.
[0035] In some preferred embodiments, a guide wedge surface is provided at the end of the cutting groove 120, and under the guidance of the guide wedge surface, the cutting knife can smoothly extend from the end into the cutting groove 120.
[0036] In some preferred embodiments, the film bonding device further includes a guide assembly 400, which includes a first guide roller 410 and a second guide roller 420 parallel to the strip groove 110, and the first guide roller 410 and the second guide roller 420 are rotatably mounted on both sides of the strip groove 110. In order to guide the plastic film on both sides of the strip groove 110 by using the first guide roller 410 and the second guide roller 420 respectively.
[0037] In addition, the utility model provides a food packaging machine equipped with the above-mentioned film splicing device.
[0038] The end of the first section of plastic film is passed through the strip groove 110 from the front of the mounting seat 100 and wound around the back of the mounting seat 100, and then the first section of plastic film is clamped by the first film inlet clamp 210 and the first film outlet clamp 220, so as to tighten the first section of plastic film. The end of the second section of plastic film is also passed through the strip groove 110 from the front of the mounting seat 100 and wound around the back of the mounting seat 100, and then the second section of plastic film is clamped by the second film inlet clamp 310 and the second film outlet clamp 320, so as to tighten the second section of plastic film. The first section of plastic film and the second section of plastic film are connected together from the front of the mounting seat 100 by using adhesive tape, and under the guidance of the guide wedge surface, the cutting knife can smoothly extend from the end into the cutting groove 120, and the operator can use the cutting knife to cut the plastic film along the strip groove 110, so as to efficiently remove the end of the plastic film. The connection operation of the plastic film is finally completed. By utilizing the film splicing device provided by the utility model, the plastic film can be stretched before splicing, thereby avoiding the problems of plastic film dislocation and plastic film wrinkles caused by the film splicing operation.
[0039] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
