Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fruit packaging, in particular to a box body packaging machine for boxed fruit. BACKGROUND

[0002] In the fruit planting area, a large number of single type of fruit are usually planted, such as the kiwi fruit planting area in Mei County, Shaanxi Province. After the fruit ripens, it can be sold to other places through industrial packaging and packaging, thereby increasing the economic income of the growers. At present, the fruit is usually packaged with a paper box. After the fruit is loaded into the paper box, the top cover plate of the paper box is closed, and the paper box is wrapped with adhesive tape. However, for kiwi fruit, the temperature inside the closed box body during transportation is higher than the normal temperature, which causes the kiwi fruit to rot and affects sales. In addition, the conventional box body needs to be wrapped with adhesive tape, which causes excessive use of adhesive tape.

[0003] Based on the above reasons, when packaging kiwi fruit, the box body shown in the specification attached to the present application is usually used. Fig. 1-2 The box body has left and right symmetrical and longitudinally arranged cover plates on the top side, and a clamping protruding plate that can be inserted through each side cover plate is arranged at an interval on the laterally symmetrical side of the box body. A through hole (not shown in the figure) is formed in the cover plate for inserting the clamping protruding plate. When the box body is used, a plurality of fruits are first placed in the box body, and then the cover plates on each side are driven to flip towards the horizontal direction as shown by the curved arrow in the figure. When the cover plates contact the clamping protruding plate, a downward clamping force is continuously applied to the cover plates, so that the clamping protruding plate is inserted into and passes through the through hole of the cover plate, thereby completing the packaging of the box body (as shown on the right side of the figure in the specification). Fig. 1-2 The inner size of the through hole is slightly smaller than the outer size of the clamping protruding plate. The box body is usually made of paper, and the clamping protruding plate can be inserted into the through hole of the cover plate by external force. This solves the problem of the difficulty of using adhesive tape to wrap the cover plates on both sides of the conventional box body after they are closed, and the problem of the large amount of adhesive tape used. The cover plates on both sides are left with a certain interval after clamping, so that the fruits inside are exposed. This avoids the temperature inside the box body from being too high, and facilitates the display of the fruits during the later sales process, and facilitates the opening of each side cover plate in the opposite direction to take out the fruits during the later consumption. Fig. 1-2 Since the through hole in the cover plate of the box body is smaller than the size of the clamping protruding plate, a large downward clamping force needs to be applied by the operator's fingers during clamping, so that the cover plate can be clamped on the clamping protruding plate. In continuous packaging operations, the operator's physical burden is easily caused, which affects the work efficiency of continuous packaging, and the thumb is usually used for clamping, which easily causes tendinitis and causes occupational diseases.

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application will be further described below in combination with the drawings and examples.

[0025] Referring to the drawings Fig. 1-12 The box body packaging machine for boxed fruit, the box body 1 top side has left and right symmetrical and longitudinally arranged cover plate 11, and on the laterally symmetrical side of the box body 1, the embedding through each side cover plate 11 buckling convex plate 12 is arranged at intervals, and the through hole (not shown in the figure) embedding through the buckling convex plate 12 is arranged on the cover plate 11, and the packaging is completed by turning over the cover plate 11 and driving it to buckle on the buckling convex plate 12, that is, the packaging of the box body 1 is completed.

[0026] In order to solve the problem that the operator needs to exert a large downward buckling force by hand during the packaging and buckling of the box body 1, which causes the operator to bear too much physical burden, affects the operation efficiency of continuous packaging, and easily causes tendinitis and other problems, the present application provides a packaging machine suitable for the buckling and packaging of the box body, such as Fig. 3-4As shown, it includes a frame 2, which is preferably welded from square steel pipes and has an operating surface on the top. On both sides of the frame 2 are provided a pressing mechanism that abuts against the cover plate 11 and drives the cover plate 11 to fit into and penetrate the pressing convex plate 12. That is, the pressing mechanism mechanically drives the cover plate 11 to flip and press it against the pressing convex plate 12, thereby solving the problem of the operator's current finger pressing, which is physically demanding and prone to occupational diseases. At the same time, it effectively improves the continuous packaging efficiency of the box body 1.

[0027] Specifically, such as Fig. 3-4 As shown, the buckling mechanism includes support plates 21 symmetrically arranged on both sides of the frame 2, and each side of the support plate 21 is provided with a double roller group 3 whose bottom surface contacts the surface of the horizontal cover plate 11, as shown in FIG. Fig. 5-8 As shown, the box body 1 with the covering plate 11 in the open state is placed on the frame 2, and the box body is driven to move toward the double roller group 3. When the outer surface of the covering plate 11 on one side contacts the double roller group 3, the box body 1 continues to be pushed to move, and the covering plate 11 is flipped by the rolling action of the double roller group 3, and the bottom surface of the double roller group 3 contacts the surface of the covering plate 11 in the horizontal state, that is, the covering plate 11 is rolled by the double roller group 3 to be flipped to the horizontal covering state, and the extrusion damage to the box body 1 is avoided, so that the buckling operation of the covering plate 11 and the buckling convex plate 12 is mechanically completed by the rolling action of the double roller group 3, which effectively solves the physical burden of manual finger buckling and improves the efficiency of continuous buckling.

[0028] In the buckling process of the double roller group 3, in order to avoid the deflection and damage caused by the contact and extrusion of the buckling convex plate 12, as shown in FIG. Fig. 4 As shown, a groove 3a is reserved in the middle of the dual roller assembly 3 for embedding the retaining plate 12. When the box body 1 is driven to move, the retaining plate 12 is aligned with the groove 3a, so that the dual roller assembly 3 contacts and rolls with the surface of the cover plate 11, while the retaining plate 12 passes through the groove 3a, avoiding squeeze damage to the retaining plate 12. At the same time, when the retaining plate 12 is located in the groove 3a, the inner sidewall of the dual roller assembly 3 provides short-term support for the retaining plate 12, preventing the paper retaining plate 12 from deflecting under the strong retaining force of the cover plate 11.

[0029] like Fig. 8As shown, the above buckling method can only achieve buckling operation on the single side (left side in the figure) of the cover plate 11, and the other side (right side) of the cover plate 11 is in an open state. After continuing to move and contacting the double roller set 3, the double roller set 3 will drive the right side of the cover plate 11 to continue to flip towards the right (outside) side, and cannot achieve smooth buckling and closing operation to the left side. Manual operation is required to flip the right side of the cover plate downwards while buckling the left side to avoid the side edge of the right side of the cover plate 11 being blocked by contacting the double roller set 3, or the box body after buckling the left side is turned to the left side of the double roller set 3 to push the box body 1 to the right to achieve buckling of the right side of the cover plate 11. Whether the right side of the cover plate 11 is flipped manually in advance or the box body is turned to the left side of the double roller set 3 for further buckling of the right side of the cover plate 11, there is still a certain inconvenience in operation. Therefore, in order to solve this problem, as shown in Fig. 9 The double roller set 3 is arranged at a distance (left and right) on the frame 2 in the buckling direction of the cover plate 11, and the distance is greater than the width of the box body 1, so that the box body 1 can be smoothly placed.

[0030] As shown in Fig. 9-12 The box body 1 is placed on the conveying belt 4 between the left and right double roller sets 3, and then the conveying belt 4 is started to drive the box body 1 to move to the right. When the right side of the cover plate 11 contacts the right side of the double roller set 3, the right side of the cover plate 11 is buckled. In order to avoid the conveying belt 4 from continuing to drive the buckled box body 1 to fall off the frame 2, a sensing sensor 6 is preferably arranged on the right side of the frame 2. That is, after the right side of the double roller set 3 completes buckling of the right side of the cover plate 11 of the box body 1, the sensing sensor senses the box body 1 and feeds back to the control system (which controls the reciprocating movement of the conveying belt 4 and receives the signal feedback of the sensing sensor). The conveying belt 4 stops conveying and is started in reverse to convey the box body 1 to the left, and then the left side of the double roller set 3 is used to buckle the left side of the cover plate 11 of the box body 1. Thus, by using the double roller set 3 arranged at a distance and the reciprocating conveying belt 4, the buckling operation of the cover plate 11 on both sides of the box body 1 is completed without human intervention. After buckling the left side, the conveying belt 4 transfers the box body 1 to the roller 8 arranged on the left side of the frame 2 for transmission. The box body 1 is placed again between the double roller sets 3 arranged at a distance for double-side buckling operation, and the continuous buckling and conveying operation of the box body 1 is achieved.

[0031] In the above operation process, the box body 1 is placed on the conveying belt 4 by the operator for buckling operation. In order to avoid the influence of the double roller set 3 on the buckling convex plate 12, the buckling convex plate 12 needs to be aligned with the groove 3a of the double roller set 3 by manual naked eye, which still has a certain inconvenience in operation. Therefore, in order to solve this problem, as shown in Fig. 4As shown, the guiding wheels 5 are arranged on the side walls of the box body 1 and are close to the double roller groups 3 on each side. When the box body 1 is placed on the conveying belt 4, the side walls of the box body 1 are in rolling contact with the guiding wheels 5 on both sides during the movement of the box body 1 driven by the conveying belt 4, so that the position of the box body 1 is self-guided and adjusted, that is, the buckle pressing convex plate 12 is self-aligned with the groove 3a of the double roller group 3, and the convenience of the buckle pressing operation is further improved.

[0032] In order to avoid the problem that the box body 1 is placed on the conveying belt 4 and the deviation from the guiding wheel 5 is too large, so that the end of the box body 1 is blocked after being in contact with the guiding wheel 5 and cannot be smoothly guided, the box body 1 is placed on the conveying belt 4, and the box body 1 is placed on the conveying belt 4. Fig. 4 As shown, the elastic guiding plates 7 with arc structure are further arranged in the inner side of the supporting plate 21. When the box body 1 is placed, the symmetric elastic guiding plates 7 are used for limiting, so that the placement range of the box body 1 is reduced, the side walls of the box body 1 fall on the conveying belt 4 along the elastic guiding plates 7, and the pre-guiding effect of the elastic guiding plates 7 avoids the problem that the deviation of the box body 1 from the guiding wheel 5 is too large after being placed, so that the end of the box body 1 is blocked after being in contact with the guiding wheel 5.

[0033] The principle of the present application is that when the box body 1 is packaged, the box body 1 is placed on the conveying belt 4 between the double roller groups 3 on the left and right of the frame body 2, then the conveying belt 4 is started to drive the box body 1 to move to the right, and the guiding wheel 5 is used to guide the box body 1, so that the buckle pressing convex plate 12 corresponds to the groove 3a of the double roller group 3. When the right sealing plate 11 contacts the right double roller group 3, the buckle pressing operation of the right sealing plate 11 is realized. When the box body 1 extends to the right double roller group 3, the box body 1 is sensed by the induction sensor and fed back to the control system, the conveying belt 4 stops conveying and reversely conveys the box body 1 to the left, and then the left double roller group 3 is used to realize the buckle pressing operation of the left sealing plate 11 of the box body 1, so that the double roller groups 3 with a certain interval and the reciprocating conveying belt 4 complete the smooth buckle pressing operation of the sealing plates 1 on both sides of the box body 1 without human intervention. After the left buckle pressing is completed, the conveying belt 4 transfers the box body 1 to the roller 8 arranged on the left side of the frame body 2 for transmission. The box body 1 is placed between the double roller groups 3 with a certain interval for double-sided buckle pressing operation, and the continuous buckle pressing and conveying operation of the box body 1 is realized.

[0034] The basic principles, main features and advantages of the present application are shown and described above. Various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the claimed application.
