Technical Field

[0001] The utility model relates to the field of film packaging, in particular to a PVA medium-temperature film packaging device. Background Art

[0002] PVA, also known as polyvinyl alcohol, is an organic compound with the appearance of white flake, floc or powder solid, odorless and soluble in water. Polyvinyl alcohol is an important chemical raw material used to manufacture polyvinyl acetal, gasoline-resistant pipes, vinylon synthetic fibers, fabric treatment agents, emulsifiers, paper coatings, adhesives and glues, etc. PVA film is used for packaging products.

[0003] A Chinese patent discloses a film packaging device (authorization announcement number CN 212099441 U). This patented technology can solve the problem that the existing cling film packaging machine cannot meet the requirements of multiple packaging sizes, multiple packaging types, high packaging speed, and assembly line packaging.

[0004] However, after the existing products are coated, there is a tendency for excess part to appear on the side, which needs to be cut. When cutting with a cutter, the position of the cutter cannot be accurately determined, which makes it easy to squeeze the product excessively and cause damage to the product. Summary of the invention

[0006] Preferably: a lower platform is rotatably mounted on the bottom of the workbench through a bearing, an adjusting cylinder is rotatably plugged into the upper end surface of the fixed frame through a bearing, an upper platform is arranged at the bottom of the adjusting cylinder, and the upper platform limits and fixes the top of the product.

[0007] Preferably: an adjusting cylinder is installed at the top of the adjusting cylinder, and an upper platform is installed at the output end of the adjusting cylinder.

[0008] Preferably: a driven bevel gear is installed on the outer side wall of the adjusting cylinder, a driving bevel gear is installed on the outer side wall of the driven bevel gear in meshing rotation, and an adjusting motor is installed on the right end face of the driving bevel gear.

[0009] Preferably: a control panel is installed on the left end surface of the fixing frame, and the control panel is electrically connected to the adjusting motor.

[0010] Preferably: the bottom of the molding frame is connected to the upper end surface of the workbench by means of sliding fit.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model adopts a pressure sensor and a warning light structure, so that the cutting knife is close to the outer wall of the product, avoiding the first electric slider continuously controlling the movement of the mold frame, causing extrusion damage to the product surface.

[0013] 2. The utility model adopts a driven bevel gear and an active bevel gear structure, so that the product can be driven to rotate and cut, without the need to carry the product many times, which greatly improves the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5 In this embodiment, a PVA medium-temperature film packaging device is provided, including a workbench 1 and a fixed frame 2. The left and right side walls of the workbench 1 are installed with the fixed frame 2. A first electric slider 11 is installed on the top of the fixed frame 2. A molded frame 12 is installed on the bottom of the first electric slider 11. A second electric slider 13 is installed on the left end surface of the molded frame 12. A cutter 14 is installed on the left end surface of the second electric slider 13. A pressure sensor 15 is embedded on the left end surface of the cutter 14. A warning light 16 is installed on the front end surface of the molded frame 12. The pressure sensor 15 is electrically connected to the warning light 16. When working, the electric slider is a straight line. The guide rail slider structure drives the lead screw to rotate through the motor to control the linear movement of the device. After the product is coated, the excess part needs to be cut. The product is placed on the workbench 1, and the first electric slider 11 is started to drive the molding frame 12 to move left. When the cutting knife 14 touches the product, the pressure sensor 15 senses the pressure signal and controls the warning light 16 to sound an alarm, thereby preventing the first electric slider 11 from continuously controlling the movement of the molding frame 12, causing extrusion damage to the surface of the product. Subsequently, the second electric slider 13 is started to drive the cutting knife 14 to move downward, and the cutting knife 14 cuts the excess part of the product.

[0022] A lower platform 17 is rotatably mounted at the bottom of the workbench 1 through a bearing, an adjusting cylinder 18 is plugged into the upper end surface of the fixed frame 2 through a bearing rotation, an adjusting cylinder 21 is mounted on the top of the adjusting cylinder 18, and an upper platform 19 is mounted on the output end of the adjusting cylinder 21. During operation, the product is placed on the lower platform 17, and the upper platform 19 limits and fixes the top of the product. When fixing products of different specifications, the adjusting cylinder 21 is started to drive the upper platform 19 to move downward, thereby pressing and fixing the top of the product.

[0023] The outer wall of the adjusting cylinder 18 is installed with a driven bevel gear 22, and the outer wall of the driven bevel gear 22 is meshed and rotatably installed with a driving bevel gear 23, and the right end face of the driving bevel gear 23 is installed with an adjusting motor 24. During operation, when one side of the product is cut, the adjusting motor 24 moves to drive the driving bevel gear 23 to rotate, and the driving bevel gear 23 drives the driven bevel gear 22 to rotate, so that the adjusting cylinder 18 rotates, and then drives the product to rotate, which is convenient for cutting the outer end of the product without multiple disassembly and transportation, thereby greatly improving work efficiency.

[0024] A control panel 25 is installed on the left end surface of the fixing frame 2. The control panel 25 is electrically connected to the adjusting motor 24. When working, a PLC program is written in the control panel 25 to control the operation of each device.

[0025] The bottom of the mold frame 12 is connected to the upper end surface of the workbench 1 by a sliding fit. When working, the sliding fit is adopted to ensure the stability of the mold frame 12 moving left and right.

[0026] During specific work, after the product coating is completed, the excess part needs to be cut off, and the product is placed on the lower table 17. The upper table 19 limits and fixes the top of the product. When fixing products of different specifications, the adjusting cylinder 21 is started to drive the upper table 19 to move downward, thereby pressing and fixing the top of the product. The first electric slider 11 is started to drive the molding frame 12 to move left. When the cutting knife 14 touches the product, the pressure sensor 15 senses the pressure signal and controls the warning light 16 to sound an alarm, thereby preventing the first electric slider 11 from continuously controlling the movement of the molding frame 12, causing extrusion damage to the surface of the product. Subsequently, the second electric slider 13 is started to drive the cutting knife 14 to move downward, and the cutting knife 14 cuts the excess part of the product.

[0027] Obviously, the invention described is only a part of the invention of the utility model, not the whole invention. Based on the invention in the utility model, all other inventions obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the utility model. The structures, devices and operating methods not specifically described and explained in the utility model shall be implemented according to the conventional means in the field unless otherwise specified and limited.
