Description

Technical Field

[0001] This utility model belongs to the field of filling machines and relates to a film forming device for a card-type filling machine. Background Technology

[0002] Traditional card-type filling machines use a motor to drive a moving mold towards a fixed mold via a screw, thus forming the film. In this method, the distance the moving and fixed molds travel is determined by the motor's rotation, which has two main drawbacks: First, film forming requires a certain speed before the film is fully cooled, and this method, relying solely on the motor's rotation to move the moving mold towards the fixed mold, is relatively slow. Second, because filling machine production lines are typically large, manufacturers strive to minimize the machine's size; this method, relying solely on the motor's rotation to determine the distance between the moving and fixed molds, occupies a significant amount of space. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a film forming device for a card-type filling machine. This device has the advantages of rapid mold closing and reduced horizontal space occupation.

[0004] The purpose of this utility model is achieved as follows:

[0005] A film forming device for a card-type filling machine includes a fixed base, a bracket fixed on the fixed base, a plurality of guide posts on the bracket, the guide posts passing through the bracket and slidingly engaging with the bracket, a first movable seat and a second movable seat respectively on both sides of the bracket, the first movable seat and the second movable seat respectively fixed at both ends of the guide posts, a movable mold seat between the second movable seat and the bracket, the movable mold seat slidably disposed on the guide posts, a first mold fixed on the end face of the movable mold seat facing the second movable seat, and a second mold fixed on the end face of the second movable seat facing the movable mold seat, the first mold and the second mold cooperating to form a film forming mold;

[0006] A motor is mounted on the bracket. The output end of the motor extends downward and is connected to a screw. A nut is fitted on the screw, and an intermediate connecting rod is fixed on the nut. A first hinge seat is fixed to the end face of the first movable seat facing the intermediate connecting rod. The first connecting rod is hinged to the first hinge seat, and the first connecting rod is hinged to the near end of the intermediate connecting rod. A second hinge seat is fixed to the end face of the moving mold seat facing the intermediate connecting rod. A second connecting rod is hinged to the second hinge seat, and the second connecting rod is hinged to the near end of the intermediate connecting rod.

[0007] With the above setup, when the mold opens, the motor rotates, causing the nut to rise. The nut then raises the intermediate connecting rod, which in turn moves the first and second connecting rods closer to the center. This, in turn, moves the first movable seat and the moving mold base closer to the center. Since both the first and second movable seats are fixed to the guide pillars, which slide against the support, the first movable seat moves closer to the center while simultaneously moving the second movable seat away from the intermediate connecting rod. At this time, because the moving mold base moves closer to the intermediate connecting rod while the second movable seat moves away, the movement speed of both the moving mold base and the second movable seat is increased. Furthermore, because the directions of the motor and screw are perpendicular to the directions of the moving mold base and the second movable seat, the longitudinal space is fully utilized, reducing the horizontal space occupied.

[0008] When the mold closes, the motor rotates, causing the nut to reset. The nut then resets the intermediate connecting rod, which in turn moves the first and second connecting rods away from each other, thus causing the first movable seat and the moving mold seat to move away from each other. Since both the first and second movable seats are fixed to the guide pillars, which slide against the support, the first movable seat moves away from the center while simultaneously moving the second movable seat closer to the intermediate connecting rod. At this time, because the moving mold seat moves away from the sides (i.e., towards the second movable seat), and the second movable seat moves closer to the intermediate connecting rod, the mold closing speed of the moving mold seat and the second movable seat is accelerated.

[0009] The present invention is further configured such that a first linear bearing is sleeved between the guide post and the bracket.

[0010] The present invention is further configured such that a second linear bearing is sleeved between the moving mold base and the guide post.

[0011] The present invention is further configured such that: the intermediate connecting rod includes an intermediate fixed section and two hinged sections on both sides; the intermediate fixed section is also formed with a mounting hole; a nut is sleeved in the mounting hole and fixedly connected to the fixed section; the two hinged sections are respectively formed with hinge grooves; one hinge groove is hinged to the first connecting rod, and the other hinge groove is hinged to the second connecting rod.

[0012] With the above settings, the two ends of the intermediate link are hinged to the first link and the second link respectively, and can simultaneously drive the first link and the second link to move.

[0013] The present invention is further configured such that the intermediate connecting rod is H-shaped.

[0014] The present invention is further configured such that: the nut includes a cylindrical section, a screw hole is formed in the center of the cylindrical section, an internal thread is formed in the screw hole and screwed to the screw of the motor, the cylindrical section is sleeved in the mounting hole of the intermediate connecting rod, and a fixed flange is formed at the upper end of the cylindrical section, the fixed flange is fixedly connected to the middle fixed section of the intermediate connecting rod by a screw.

[0015] With the above settings, the nut is fixedly connected to the intermediate connecting rod.

[0016] The present invention is further configured such that: the fixing base includes two fixing plates, two or more sliding columns are provided between the two fixing plates, two or more sliding plates are sleeved on the sliding columns, and the bracket is fixed on the sliding plates.

[0017] The present invention is further configured such that the direction of the sliding column is perpendicular to the direction of the guide column.

[0018] The present invention is further configured such that: a lead screw is rotatably mounted on one of the fixed plates, the lead screw is arranged parallel to the slide column, and the lead screw is screwed to one of the slide plates.

[0019] With the above settings, the lateral position of the bracket can be adjusted by rotating the lead screw to move the slide plate.

[0020] The present invention is further configured such that: a wrench is connected to the outer end of the lead screw, and a bearing is provided between the lead screw and the fixed plate.

[0021] The use of a wrench and bearings makes adjustment easier and more convenient.

[0022] The significant and beneficial technical effects of this invention compared to existing technologies are as follows: Since both the first and second movable seats are fixed on the guide pillars, and the guide pillars and the support are in sliding engagement, the first and second movable seats move in the same direction and to the same distance. The moving mold seat is connected to the intermediate connecting rod via the second connecting rod, so the moving mold seat moves the same distance as the first movable seat but in the opposite direction. Therefore, during mold closing, the moving mold seat and the second movable seat move towards each other simultaneously, accelerating the mold closing speed. During mold opening, the moving mold seat and the second movable seat move away from each other simultaneously, accelerating the mold opening speed. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0030] A film forming device for a card-type filling machine includes a fixed base 1, a bracket 2 fixed on the fixed base 1, a plurality of guide posts 3 on the bracket 2, the guide posts 3 passing through the bracket 2 and slidingly engaging with the bracket, a first movable seat 4 and a second movable seat 5 respectively on both sides of the bracket, the first movable seat 4 and the second movable seat 5 respectively fixed to the two ends of the guide posts 3, a movable mold seat 6 is provided between the second movable seat 5 and the bracket 2, the movable mold seat 6 is slidably disposed on the guide posts 3, a first mold 7 is fixed on the end face of the movable mold seat 6 facing the second movable seat 5, and a second mold 8 is fixed on the end face of the second movable seat 5 facing the movable mold seat 6, the first mold 7 and the second mold 8 cooperate to form a film forming mold;

[0031] A motor 9 is mounted on the bracket. The output end of the motor 9 extends downward and is connected to a screw 10. A nut 11 is fitted on the screw 10. An intermediate connecting rod 12 is fixed on the nut 11. A first hinge seat 13 is fixed to one end of the first movable seat 4 facing the intermediate connecting rod 12. A first connecting rod 14 is hinged to the first hinge seat 13. The first connecting rod 14 is hinged to the near end of the intermediate connecting rod 12. A second hinge seat 15 is fixed to one end of the movable mold seat 6 facing the intermediate connecting rod 12. A second connecting rod 16 is hinged to the second hinge seat. The second connecting rod 16 is hinged to the near end of the intermediate connecting rod 12.

[0032] With the above setup, when the mold opens, the motor 9 rotates, causing the nut 11 to rise. The nut then drives the intermediate connecting rod 12 to rise, which in turn drives the first connecting rod 14 and the second connecting rod 16 to move closer to the center. This, in turn, moves the first movable seat 4 and the moving mold seat 6 closer to the center. Since both the first movable seat 4 and the second movable seat 5 are fixed on the guide pillar, and the guide pillar and the bracket are in sliding fit, the first movable seat 4 and the second movable seat 5 move in the same direction and to the same distance. The moving mold seat 6 is connected to the intermediate connecting rod 12 via the second connecting rod 16. Therefore, the moving mold seat 6 moves the same distance as the first movable seat 4, but in the opposite direction. Thus, while the first movable seat 4 moves closer to the center, it drives the second movable seat 5 to move away from the intermediate connecting rod. At the same time, the moving mold seat moves closer to the intermediate connecting rod, thus accelerating the mold opening speed of the moving mold seat and the second movable seat.

[0033] When the mold closes, the motor 9 rotates, causing the nut 11 to reset. The nut then drives the intermediate connecting rod 12 to reset, and the intermediate connecting rod 12 drives the first connecting rod 14 and the second connecting rod 16 to move away from each other, thereby causing the first movable seat 4 and the moving mold seat 6 to move away from each other. Since the first movable seat 4 and the second movable seat 5 are both fixed on the guide post, and the guide post and the bracket are in sliding fit, the first movable seat 4 moves away from the center while simultaneously driving the second movable seat 5 to move closer to the intermediate connecting rod. At this time, because the moving mold seat 6 moves away from the sides (that is, towards the second movable seat), and the second movable seat moves closer to the intermediate connecting rod, the mold closing speed of the moving mold seat and the second movable seat is accelerated.

[0034] A first linear bearing 17 is sleeved between the guide post 3 and the bracket 2.

[0035] A second linear bearing 18 is sleeved between the moving mold base 6 and the guide post 3.

[0036] The intermediate connecting rod 12 includes a central fixed section 19 and two hinged sections 20 on both sides. The central fixed section 19 is also formed with mounting holes 21. Nuts 11 are fitted into the mounting holes 21 and fixedly connected to the fixed section 19. The two hinged sections 20 are respectively formed with hinge grooves 22. One hinge groove 22 is hinged to the first connecting rod 14, and the other hinge groove 22 is hinged to the second connecting rod 16. The intermediate connecting rod is H-shaped. Through the above arrangement, the two ends of the intermediate connecting rod are respectively hinged to the first connecting rod and the second connecting rod, and can simultaneously drive the first connecting rod and the second connecting rod to move.

[0037] The nut 11 includes a cylindrical section 23 with a threaded hole 24 formed at its center. The threaded hole 24 has an internal thread that connects to the screw rod 10 of the motor. The cylindrical section is fitted into the mounting hole 21 of the intermediate connecting rod 12. A fixing flange 25 is formed at the upper end of the cylindrical section, and the fixing flange 25 is fixedly connected to the middle fixing section of the intermediate connecting rod by a screw. Through these features, the nut is fixedly connected to the intermediate connecting rod.

[0038] The fixing base 1 includes two fixing plates 26, and two or more sliding pillars 27 are provided between the two fixing plates 26. Two or more sliding plates 28 are sleeved on the sliding pillars 27, and the bracket 2 is fixed on the sliding plate 28. The direction of the sliding pillar 27 is perpendicular to the direction of the guide pillar 3.

[0039] A lead screw 29 is rotatably mounted on one of the fixed plates 26. The lead screw 28 is parallel to the sliding column 27 and is screwed to one of the sliding plates 28. With this configuration, rotating the lead screw can move the sliding plate, thereby adjusting the lateral position of the bracket.

[0040] A wrench 30 is connected to the outer end of the lead screw 29, and a bearing is provided between the lead screw and the fixed plate. The wrench and bearing make adjustment easier and more convenient.

[0041] This invention features rapid mold closing and reduced horizontal space occupation.

[0042] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
