Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, and particularly relates to a tape sealing structure for a fruit packing box. Background Art

[0002] Before the fruits are transported out of the warehouse, it is necessary to paste and seal the packing box containing the fruits. The commonly used bonding and sealing method is tape sealing. With the continuous improvement of the use requirements, people also put forward higher requirements for the performance of the tape pasting device for fruit packing boxes.

[0003] At present, for the existing tape sealing structure of fruit packing boxes, when sealing the fruit packing boxes with tape, only the bottom of the packing box is fixed. During the tape sealing process, the top of the fruit packing box is not firmly fixed, resulting in the phenomenon that the tape does not paste at the middle position as required and the tape is pasted obliquely. It needs to be bonded multiple times, which is time-consuming and laborious and increases the material cost. The fruit packing box is not firmly pasted, affecting transportation and sales. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tape sealing structure for a fruit packing box to solve the problem of the insecure fixation of the top during the tape sealing process of the fruit packing box.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A tape sealing structure for a fruit packing box, including a conveying mechanism arranged on a support frame. Brackets are arranged on both sides of the support frame. A cross beam with adjustable height is arranged on the brackets. An upper sealing mechanism for fixing the closed end of the box body is arranged on the cross beam. A bottom clamping conveying mechanism is arranged above the conveying mechanism. A top clamping mechanism is arranged on the bottom clamping conveying mechanism. The top clamping mechanism includes a fixed block, a moving block, a longitudinal lead screw, a longitudinal screw, a top clamping block, a transverse screw, and a transverse lead screw. The longitudinal lead screw penetrates through the moving block longitudinally. The end of the longitudinal lead screw is fixedly connected to the fixed block. A longitudinal screw is arranged at one end of the longitudinal lead screw. The transverse lead screw penetrates through the moving block transversely. The end of the transverse lead screw is fixedly connected to the top clamping block. A transverse screw is arranged at one end of the transverse lead screw.

[0006] Further, the bottom clamping conveying mechanisms are symmetrically arranged on the conveying mechanism. The distance between the two bottom clamping conveying mechanisms is adjusted by a bidirectional lead screw. The adjustment of the bidirectional lead screw is carried out by an adjustment handwheel. The conveyor belt of the bottom clamping conveying mechanism is driven by a motor.

[0007] Further, a lower sealing mechanism penetrates through the middle position of the conveying mechanism.

[0008] Further, the cross beam moves up and down on the bracket through a lead screw, and the lead screw is rotationally adjusted through an adjusting hand wheel.

[0009] Further, universal wheels are provided at the bottom of the support frame.

[0010] The utility model has the following beneficial effects:

[0011] By setting an adjustable top clamping mechanism, the fruit packing box tape sealing structure can facilitate adjusting the positions of the top clamping blocks of the top clamping mechanism horizontally and longitudinally according to packing boxes of different sizes. The left and right sides of the top of the packing box are closely attached to the inner sides of the top clamping blocks and move forward along the inner sides of the top clamping blocks, avoiding the movement of the top of the packing box when the upper sealing mechanism seals the box with tape, effectively avoiding the time-consuming and laborious situation caused by the tape sticking obliquely and increasing the material cost, ensuring that the fruit packing box is firmly pasted, and facilitating transportation and sales.

[0020] Referring to Figures 1 - 5 , a tape sealing structure for a fruit packing box provided by the present invention includes a conveying mechanism 6 arranged on a support frame 5. Brackets 4 are arranged on both sides of the support frame 5, and a cross beam 7 with adjustable height is arranged on the brackets 4. The cross beam 7 moves up and down on the brackets through a lead screw 11, so as to perform a sealing operation on fruit packing boxes of different sizes. The lead screw 11 is rotationally adjusted through an adjusting handwheel 8.

[0021] An upper sealing mechanism 1 for fixing the closed end of the box body is arranged on the cross beam 7. A lower sealing mechanism 9 is arranged through the middle position of the conveying mechanism 6. The upper sealing mechanism 1 and the lower sealing mechanism 9 are used to perform a tape sealing operation on the fruit packing box. A bottom clamping conveying mechanism 3 is arranged above the conveying mechanism 6. The bottom clamping conveying mechanism 3 is symmetrically arranged on the conveying mechanism 6. By arranging the bottom clamping conveying mechanism 3, it is convenient to clamp and convey the bottom of the fruit packing box to prevent the packing box from moving randomly during the sealing operation of the lower sealing mechanism 9. A top clamping mechanism 2 is arranged on the bottom clamping conveying mechanism 3. By arranging the top clamping mechanism 2, it is convenient to fix the top of the fruit packing box and move it forward along the inner side of the top clamping block to prevent the packing box from moving randomly during the sealing operation of the sealing mechanism 1. The top clamping mechanism 2 includes a fixed block 201, a moving block 202, a longitudinal lead screw 203, a longitudinal screw 204, a top clamping block 205, a transverse screw 206, and a transverse lead screw 207. The longitudinal lead screw 203 penetrates through the moving block 202 longitudinally. The end of the longitudinal lead screw 203 is fixedly connected to the fixed block 201. A longitudinal screw 204 is arranged at one end of the longitudinal lead screw 203. During use, by rotating the longitudinal screw 204, the longitudinal lead screw 203 is driven to rotate, and the moving block 202 can move up and down longitudinally;

During use, by rotating the transverse screw 206, the transverse lead screw 207 is driven to rotate, and the top clamping block 205 is pushed to move horizontally transversely.

[0023] Among them, the bottom clamping and conveying mechanism 3 is symmetrically arranged on the conveying mechanism 6. The distance between the two bottom clamping and conveying mechanisms 3 is adjusted by the bidirectional lead screw 301, and the adjustment of the bidirectional lead screw 301 is carried out by adjusting the handwheel 8. The conveyor belt 302 of the bottom clamping and conveying mechanism 3 is driven by the motor 303. Universal wheels 10 are arranged at the bottom of the support frame 5 for easy movement.

[0024] Working process: During use, first, according to the size of the fruit packing box, adjust the height of the cross beam 7 by rotating the adjusting handwheel 8 until the upper carton sealing mechanism 1 on the cross beam 7 is at the height where tape carton sealing can be performed. Then, adjust the distance between the bottom clamping and conveying mechanisms 3 by adjusting the bidirectional lead screw 301. After completion, first rotate the longitudinal screw 204 to drive the longitudinal lead screw 203 to rotate, adjust the up and down movement of the moving block 202, and realize the up and down movement of the top clamping block 205. Then, rotate the transverse screw 206 to drive the transverse lead screw 207 to rotate, and realize the horizontal transverse movement of the top clamping block 205 until the inner sides of the top clamping blocks 205 are closely attached to the left and right sides of the top of the fruit packaging box. Then, place the packing box on the conveying mechanism 6 for conveying until the bottom end enters the middle position of the bottom clamping and conveying mechanism 3 and the top closely enters the inner sides of the top clamping blocks 205, and convey forward. After passing through the upper carton sealing mechanism 1 and the lower carton sealing mechanism 9, tape carton sealing is completed.
