[0002] In the current market, the packaging process of medical finger cots is mainly divided into three steps: removing the cots, bagging and cutting. Although some cot packaging machines have been used in the production process, most equipment still relies on manual operation in the bagging process, and a small part relies on mechanical equipment for bagging. Due to the adsorption and film characteristics of the cots, the following problems often occur during the bagging process:

[0003] First, when mechanical equipment is used for bagging, the finger sleeves adsorbed on the clamping jaws will be brought out during the extension of the clamping jaws, resulting in insufficient number of finger sleeves in the packaging bag.

[0004] Secondly, the finger sleeves are often misplaced or mixed up in the packaging bag during transportation, so that the finger sleeves are stuck at the opening of the packaging bag, making it impossible to completely seal the bag during the sealing process.

DETAILED DESCRIPTION

[0033] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0034] like Figure 1-10 As shown, a bag pressing device for a finger sleeve packaging machine includes a base frame 1, and a material tray 2, a bagging platform 3 and a sealing mechanism 4 are arranged in sequence on the upper end of the base frame 1 in one direction. The structure of the bagging platform 3 can be referred to Figure 3 It includes a horizontal main body and a side panel arranged at the rear of the main body. The side panel plays the role of isolating the installation, and the main body plays the role of receiving the packaging bag 1a and cooperating with the pressing during the bagging process. Figure 1 As shown, the packaging bag 1a is drawn out from the material tray 2, loaded into the finger sleeve through the bagging platform 3, and then transferred to the sealing mechanism 4 to seal the opening of the packaging bag 1a. For details, refer to Fig.10When the packaging bag 1a passes through the bagging platform 3, the finger film clamping device 12 on one side thereof will clamp the finger film on the finger film conveyor 11 which is transmitted in the same direction as the packaging bag 1a and put it into the packaging bag 1a on the bagging platform 3. The opening of the bagging platform 3 faces downwards. The finger film clamping device 12 or the finger film conveyor 11 has a device on the side of the bottom frame 1 close to the opening of the packaging bag 1a which can open the opening of the packaging bag 1a when the finger sleeve is placed. When the finger sleeve is placed in the packaging bag 1a on the bagging platform 3, in order to prevent the finger film clamping device 1 When the clamping jaws of 2 extend out of the packaging bag 1a, the finger film with the characteristics of plastic film will be adsorbed on the clamping jaws and carried out with it, which will affect the subsequent sealing and slitting processes. Therefore, this problem is solved by providing a fingertip pressing mechanism 5, which is provided on the bagging platform 3 on the side opposite to the opening of the packaging bag 1a. When the clamping jaws of the finger film clamping device 12 hold the finger sleeve and extend into the packaging bag 1a, the fingertip pressing mechanism 5 cooperates with the bagging platform 3 to press the part of the finger sleeve other than the clamping jaws from the outside of the packaging bag 1a.

[0035] Specifically, refer to Figure 1 , 2 and 4, the fingertip pressing mechanism 5 includes at least one first cylinder 51. In this embodiment, two first cylinders 51 are provided. The piston rod of the first cylinder 51 is vertically upward. The body is installed on the base frame 1. The first cylinder 51 is arranged close to the bagging platform 3. The position of the first cylinder 51 is opposite to the position of the opening side of the packaging bag 1a. The piston rod ends of the two first cylinders 51 are jointly provided with a connecting portion 52. The side of the connecting portion 52 close to the bagging platform 3 is provided with a mounting plate 53. The mounting plate 53 is a thin long plate, and its length direction is consistent with the conveying direction of the packaging bag 1a. The mounting plate 53 is a thin long plate, and its length direction is consistent with the conveying direction of the packaging bag 1a. A presser foot 54 is provided on the plate 53, and the presser foot 54 is provided along the length direction of the mounting plate 53. The presser foot 54 can be in various shapes, such as a long strip structure, or a short sheet structure with uniform intervals. When a long strip structure is adopted, one presser foot 54 can press all the finger sleeves sent into the packaging bag 1a, but deformation may occur, resulting in air supply and warping in the middle or on both sides, thereby the pressing effect is not good. When a short sheet structure with uniform intervals is adopted, it needs to be determined according to the number of clamping claws, and prefabricated one-to-one pressing is performed, and the effect is good, but it needs to be matched with the number of clamping claws.

[0036] During the working process of the fingertip pressing mechanism 5, after the clamping claw of the finger film clamping device 12 clamps the finger sleeve from the finger film conveyor 11, it extends into the packaging bag 1a that is stretched open on the bagging platform 3. At this time, the piston rod of the first cylinder 51 contracts, and moves toward the main part of the bagging platform 3 with the presser foot 54 through the connecting part 52 and the mounting plate 53, and presses the packaging bag 1a from the outside of the packaging bag 1a together with the bagging platform 3. At this time, the pressed finger sleeve part is the part outside the clamping claw, which is the fingertip part in the actual production process. After clamping, the clamping claw releases and withdraws from the packaging bag 1a, so that the phenomenon of clamping claw adsorption can be avoided, thereby improving the product packaging quality and qualified rate.

[0037] During the processing, the number of finger sleeves in each packaging bag is different according to the needs of customers. Therefore, before processing different batches, it is necessary to set the extension and retraction lengths of the piston rod of the first cylinder 51. The purpose is to prevent the pressure of the first cylinder 51 from being too high, causing the presser foot 54 to damage the packaging bag 1a or the finger sleeve. In order to simplify this adjustment step, an elastic plate 7 is provided on the bagging platform 3. The elastic plate 7 is an elastic metal plate or a plastic plate. For details, refer to Figure 4 and 6 The elastic plate 7 includes a horizontal portion in the middle and curved portions at both ends. The curved portions at both ends are bent downward to give them a certain degree of elasticity. The elastic plate 7 is located directly below the presser foot 54 and is movably installed on the bagging platform 3 through a pin or a screw. The length of the horizontal portion of the elastic plate 7 is not less than the length of the mounting plate 53, more specifically, not less than the overall length of the presser foot 54.

[0038] In addition, in order to solve the problem of sliding and deflection during the conveying process of the packaging bag 1a, we added a smooth strip 6 structure on the basis of the above, such as Figure 1 , 2 As shown in Figure 5, the flow strip 6 is arranged on one side of the bagging platform 3, and is located on the same side as the fingertip pressing mechanism 5. The flow strip 6 can cooperate with the bagging platform 3 to press the packaging bag 1a being conveyed. Specifically, the flow strip 6 includes at least one second cylinder 61. In this embodiment, two second cylinders 61 are arranged. The second cylinder 61 is arranged on the side of the bagging platform 3, and its piston rod is vertically upward. A wheel frame 62 is provided at the end of the piston rod of the second cylinder 61, and a plurality of pressing wheels 63 are provided at intervals at the bottom of the wheel frame 62. The downward pressing position of the wheel frame 62 is roughly located in the middle of the packaging bag 1a, which is staggered from the position of the presser foot 54, and the setting direction of the pressing wheel 63 is consistent with the conveying direction of the packaging bag 1a.

[0039] The specific working principle of the flow strip 6, in the above steps, the presser foot 54 presses the finger sleeve, and the clamp withdraws from the packaging bag 1a. The packaging bag 1a needs to be sealed and cut later. At this time, the second cylinder 61 is started, and the second cylinder 61 drives the wheel frame 62 to press down. After pressing the packaging bag 1a, the fingertip pressing mechanism 5 rises, that is, the flow strip 6 and the fingertip pressing mechanism 5 operate alternately. At this time, the slitting device is started, driving the packaging bag 1a to be conveyed forward. During the conveying process of the packaging bag 1a carrying the finger sleeve, the pressing wheel 63 presses on the packaging bag 1a, reducing the displacement of the finger sleeve relative to the packaging bag 1a, ensuring the qualified rate of the bag cutting process, and reducing the phenomenon of bag cutting failure caused by the finger sleeves wandering around in the packaging bag 1a during the conveying process.

[0040] In addition, it also includes a brush 8, such as Figure 7 As shown, the brush 8 is arranged on one side of the bagging platform 3, and the brush head of the brush 8 can press the conveyed packaging bag 1a, further preventing the finger sleeves from moving randomly.

[0041] In order to monitor the quality of the packaging bag 1a, a packaging bag identification sensor 9 is also provided. The packaging bag identification sensor 9 is arranged on the side of the base frame 1 close to the material tray 2. It can detect the quality of the packaging bag 1a, avoid packaging bag damage, folding, etc., and reduce invalid bagging.

[0042] like Figure 2 and 8 As shown, it also includes a sealing mechanism 4 and a transmission roller group 10. The sealing mechanism 4 includes a lower sealing plate 41 and an upper sealing plate 42 that are horizontally arranged and parallel to each other. The lower sealing plate 41 and the upper sealing plate 42 are installed on the bottom frame 1 through screws. The side where the lower sealing plate 41 and the upper sealing plate 42 are close to each other is provided with a sealing groove 43. The sealing groove 43 is in a straight line shape and is adapted to the self-sealing edge of the packaging bag 1a. When the finished packaging bag 1a passes through the sealing mechanism 4, the excess air in the packaging bag 1a can be discharged through the squeezing of the lower sealing plate 41 and the upper sealing plate 42, and when the self-sealing edge of the packaging bag 1a passes through the sealing groove 43, the upper and lower self-sealing edges are pressed together to make it closed, thereby achieving the purpose of sealing the edge and discharging excess air.

[0043] like Fig. 9As shown, the transmission roller group 10 is arranged on the base frame 1. There are two groups of transmission roller groups 10, which are respectively located at the two ends of the bagging platform 3. The transmission roller group 10 includes a support plate 101 and a pressure roller. The support plate 101 is arranged on the base frame 1. The pressure roller includes a floating pressure roller 102 and a fixed pressure roller 103. The floating pressure roller 102 and the fixed pressure roller 103 are respectively arranged on the support plate 101. The spacing between the floating pressure roller 102 and the fixed pressure roller 103 is adjustable. The outer surfaces of the floating pressure roller 102 and the fixed pressure roller 103 are formed with an outer circular groove 104. The outer circular groove 104 corresponds to the position of the sealing groove 43 and is adapted to the self-sealing edge of the packaging bag 1a. During the transmission process of the packaging bag 1a, the air can also be discharged and the packaging bag 1a can be flattened by squeezing the floating pressure roller 102 and the fixed pressure roller 103. In addition, the position of the floating pressure roller 102 relative to the fixed pressure roller 103 can be adjusted, which can adapt to packaging bags 1a of more specifications.

[0044] By improving the finger sleeve packaging machine, the occurrence of loose sealing and bag cutting failure caused by the finger sleeve moving around and deviating is reduced, thereby improving the product qualification rate.

[0045] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, several modifications, improvements and substitutions can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
