Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a portable cutter for degradable cling film. Background Art

[0002] Agricultural products refer to primary products from planting, forestry, animal husbandry and fishery, that is, plants, animals, microorganisms and their products obtained in agricultural activities, such as melons, fruits, vegetables, poultry, fresh eggs and edible fungi; in order to ensure freshness and hygiene during transportation, these agricultural products need to be covered with degradable plastic wrap before refrigerated transportation.

[0003] The degradable cling film is wound on a tube base to form a degradable cling film roll. During the wrapping work, the staff needs to use a cutter to guide, pull out and cut the degradable cling film on the degradable cling film roll. Since the overall shape of the cutter is fixed, the size of the degradable cling film roll that can be clamped (including the diameter of the tube base and the overall axial length) is limited. When wrapping different types of agricultural products, the cutter has poor adaptability, and is large in size and inconvenient to carry for the staff who need to transfer workstations. Therefore, in order to solve the above problems, a portable cutter for degradable cling film is proposed. Utility Model Content

[0004] The utility model aims to provide a portable cutter for degradable cling film to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A portable cutter for degradable cling film comprises a box, wherein an opposing sliding mechanism is arranged inside the box, wherein a pair of rotating seats are installed on the opposing sliding mechanism, wherein one end of a connecting rod is rotatably installed on the rotating seats, and a support plate is fixedly installed on the other end of the connecting rod, and a side baffle is rotatably installed on the side where the support plates are close to each other, an elastic member is fixedly installed between the connecting rods, and a limiting plate is fixedly installed on the side where the rotating seats are close to each other, and a sliding knife assembly is fixedly installed on the upper side of the box.

[0007] Specifically, the opposing sliding mechanism includes a gear and a rack. A gear is rotatably installed at the inner center of the box, and racks are slidably installed on the upper and lower sides of the box through linear guide rails. The racks are respectively located on the left and right sides of the gear, and the racks are meshed with the gears. The ends of the racks that are away from each other are respectively fixedly assembled with the rotating seats.

[0008] Furthermore, a slot for passing the rotating seat is opened on the left side of the box, and the distance between the rotating seats in the vertical direction is greater than the outer diameter of the elastic member.

[0009] Specifically, when the connecting rod swings to abut against the limiting plate, the elastic member is located on the left side of the rotating seat pin column, and when the supporting plate swings to abut against the box, the elastic member is located on the right side of the rotating seat pin column.

[0010] Specifically, a stepped shaft is fixedly mounted on one side of the side baffles that are close to each other, and a chamfer is provided at each shaft end edge of the stepped shaft.

[0011] Specifically, the support plate is vertically arranged, and the height of the support plate is greater than the diameter of the side baffle.

[0012] In addition, the bottoms of the support plate and the box are both provided with coplanar slopes.

[0013] Furthermore, a rubber suction cup is fixedly mounted on the lower side of the slope.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a portable cutter for degradable cling film, including a box 1, which is formed by buckling a box body and a top box cover. An opposing sliding mechanism 8 is arranged inside the box 1, and the opposing sliding mechanism 8 is installed with a pair of rotating seats 7. The opposing sliding mechanism 8 can enable the two rotating seats 7 to move synchronously toward or away from each other.

[0025] The rotating seats 7 are all rotatably mounted with one end of the connecting rod 2, and the other end of the connecting rod 2 is fixedly mounted with a support plate 4, and the side of the support plates 4 close to each other are rotatably mounted with side baffles 3 through a rotating shaft, the support plates 4 provide support for the installation of the side baffles 3, and the support plates 4 can swing on the rotating seats 7 through the connecting rod 2, and the two side baffles 3 are used to clamp degradable cling film rolls of different sizes in the middle.

[0026] An elastic member 5 is fixedly installed between the connecting rods 2. The elastic member 5 is an existing component and is preferably a tension spring. It can also be other elastic components that can enable the two connecting rods 2 to have a force to swing close to each other. A limit plate 6 is fixedly installed on the side where the rotating seat 7 is close to each other. The limit plate 6 is used to limit the swing angle of the connecting rod 2. When the two connecting rods 2 swing close to each other, they will eventually be in parallel positions. A slide assembly 11 is fixedly installed on the upper side of the box 1. The slide assembly 11 is an existing component, which is mainly composed of a slide seat and a slide sliding assembly. The slide can cut the degradable cling film when it moves back and forth on the slide seat.

[0027] Specifically, Figure 4As shown, the opposing sliding mechanism 8 includes a gear 81 and a rack 82. The gear 81 is rotatably installed at the inner center of the box 1, and the gear 81 is vertically arranged. The upper and lower sides of the box 1 are slidably installed with racks 82 through linear guides 83. The racks 82 are respectively located on the left and right sides of the gear 81, and the racks 82 are meshed and assembled with the gear 81, and the ends of the racks 82 that are away from each other are respectively fixedly assembled with the rotating seat 7; the linear guide 83 is an existing component composed of structures such as slide rails and sliders, so that the rack 82 can be translated back and forth in the front and rear directions. Because the racks 82 are meshed and assembled on the left and right sides of the gear 81, the movements of the two racks 82 are synchronized, and the movement directions are opposite, thereby realizing the opposing movement of the two rotating seats 7.

[0028] Furthermore, a slot for passing the rotating seat 7 is opened on the left side of the box 1, and the distance between the rotating seats 7 in the vertical direction is larger than the outer diameter of the elastic member 5, so that the elastic member 5 can pass smoothly between the two rotating seats 7.

[0029] Specifically, the rotating seat 7 is mainly composed of existing components such as a seat body and a pin. When the connecting rod 2 swings to abut against the limit plate 6, the elastic member 5 is located on the left side of the pin of the rotating seat 7. When the support plate 4 swings to abut against the box 1, the elastic member 5 is located on the right side of the pin of the rotating seat 7. In this way, the connecting rod 2 has two working positions of swinging close to each other and swinging away from each other, and after swinging to the position, it will be fixed in position and will not move on its own.

[0030] Specifically, in order to improve the clamping effect of different degradable cling film rolls, a step shaft 9 is fixedly installed on the side where the side baffle plates 3 are close to each other, and a chamfer is provided at each axial end edge of the step shaft 9; the step shaft 9 has shafts of different diameters, which can be plugged into degradable cling film rolls of different diameters, and degradable cling film rolls of similar sizes can also be adapted and plugged in through chamfering, which has a wider range of applications.

[0031] Specifically, the support plate 4 is vertically arranged, and the height of the support plate 4 is greater than the diameter of the side baffle 3; so that the support plate 4 can protect the circumferential surface of the degradable cling film roll to prevent the degradable cling film from contacting the placement surface and thus adhering foreign matter.

[0032] In addition, in order to improve the placement stability of the cutter when in use, the bottom of the support plate 4 and the box 1 are provided with coplanar slopes, so that the cutter can be placed stably on the placement surface.

[0033] Furthermore, a rubber suction cup 10 is fixedly installed on the lower side of the slope. The rubber suction cup 10 is mainly an existing component composed of a rubber plate and rubber discs distributed in an array. When placed in use, it can be adsorbed on the placement surface to ensure that the whole body will not move when the degradable cling film is pulled out.

[0034] The working principle of this embodiment:

[0035] When using degradable cling film to pack agricultural products, the two connecting rods 2 are located in a position where they are swung close to each other to be parallel. At this time, after the connecting rods 2 are restricted by the limit plate 6, the elastic member 5 can still continue to move the two parallel connecting rods 2 close to each other, and the setting of the opposing sliding mechanism 8 can always keep the two connecting rods 2 moving synchronously in opposite directions, and the degradable cling film rolls of different sizes can be centrally clamped by the step shaft 9 and can be rotated with the support of the side baffle plate 3. The degradable cling film pulled from the top passes through the slide assembly 11 to the right to complete the protection of the agricultural products, and then the degradable cling film is cut off by the slide assembly 11, so that the packaging work is carried out quickly.

[0036] When the work is completed, the two connecting rods 2 are swung away from each other to take out the biodegradable cling film roll. When the support plate 4 is against the box 1, the elastic member 5 is located on the right side of the pin of the rotating seat 7. The force exerted by the elastic member 5 on the connecting rod 2 can maintain the inclined posture of the connecting rod 2 and further move closer to each other. This can reduce the overall volume and facilitate storage and carrying.
