Description

Technical Field

[0001] The present invention belongs to the technical field of binding equipment, and particularly relates to a hot melt binding machine. Background Art

[0002] Hot melt binding is a binding method that uses hot melt resin to bond multiple pages of documents, and is widely used in the binding of documents such as tender documents, contracts, and financial vouchers. The structure of a hot melt binding machine mainly includes a base where a heating tank is located, and a baffle above the base. The main steps of hot melt binding are as follows: First, place the binding side of the document facing the resin side of the envelope, and put it into a hot melt envelope; put the document and the envelope as a whole into the heating tank of the hot melt binding machine, and adjust the baffle of the heating tank to press the document tightly along the thickness direction of the document; the hot melt binding machine heats up and starts binding; the bound document is placed in a cooling tank for cooling.

[0003] In the prior art, the width specification of a hot melt binding machine needs to be adapted to accommodate multiple functional areas such as a cooling tank, a heating tank, a heating tank width adjustment module, and an electronic control panel. The height specification needs to be adapted to accommodate the height of the main body and the height of the baffle. The length specification is adapted to different standard sizes such as A4 printing paper and financial vouchers according to specific binding uses. For example, Patent CN213861518U proposes a hot melt binding machine. This device drives the front movable clamping plate to move back and forth through a push plate. The area between the front movable clamping plate and the middle fixed plate is the heating area, and a cooling port is provided between the middle fixed plate and the rear fixed plate. This device accommodates the operation panel, the movable area of the push plate, the heating area, and the cooling port area in the width direction. In addition, the heights of the middle fixed plate and the front movable clamping plate of this device are both set to 25 cm. This makes the volume of the hot melt binding machine very large when it is packed and transported, increasing the transportation cost. Summary of the Invention

[0004] In view of this, the present invention hopes to propose a hot melt binding machine that can reduce the packing volume of the hot melt binding machine during transportation and reduce the transportation cost.

[0005] The present invention is achieved through the following technical solutions: A hot melt binding machine includes a heating tank for accommodating the document to be bound, and a movable baffle and a fixed baffle for fixing the document to be bound in the heating tank. There is an adjustable distance between the movable baffle and the fixed baffle. It is characterized in that the hot melt binding machine further includes: A main body, the main body includes a control box and a heating tank arranged adjacent to each other, and the heating tank has a accommodation width adapted to the maximum binding thickness; the fixed baffle is arranged on the main body; An outer shell, the outer shell has a working track that moves back and forth along the accommodation width direction; the movable baffle is connected to the outer shell, and the movable baffle cooperates with different positions on the working track to form different distances from the fixed baffle; An electronic control panel, which is arranged on the outer casing; The electronic control panel and the movable baffle have a relatively fixed position.

[0006] In order to reduce the shipping packing volume of the hot melt binding machine, this solution optimizes the functional layout and operating structure of the hot melt binding machine. The length dimension of the hot melt binding machine needs to be adapted to the sizes of standard printed materials such as A4 and financial vouchers, and the room for improvement is limited. Therefore, this solution optimizes the layout of the hot melt binding machine in the width direction.

[0007] In the width direction, the hot melt binding machine needs to be equipped with at least an electronic control panel and a heating tank. In the prior art, the movable baffle is a movable part relatively independent of the main body of the hot melt binding machine. The position of the movable baffle in the heating tank is generally adjusted by a handle connected to the movable baffle, and the sliding range of the handle is limited by a chute on the surface of the main body of the hot melt binding machine. Both the electronic control panel and the heating tank are arranged on the surface of the main body, and the chute is arranged between the electronic control panel and the heating tank, and the space it occupies is similar to the width of the heating tank.

[0008] This solution adjusts the cooperation relationship and position relationship of the position adjustment components of the movable baffle. The outer casing drives the movable baffle to move, and the outer casing, the movable baffle and the electronic control panel as a whole are used as a movable part relatively independent of the main body of the hot melt binding machine. At this time, the space occupied by the chute is cancelled on the surface of the main body of the hot melt binding machine. When the width of the accommodation of the heating tank is the same as the width of the electronic control panel, the hot melt binding machine proposed by this solution has a smaller size during shipping and occupies less logistics space, reducing the transportation cost.

[0009] In the height direction, since the connecting member between the movable baffle and the handle is usually set as a flat plate in the prior art, the hot melt binding machine needs to accommodate at least the main body casing, the flat plate and the control component in this direction; considering the heat dissipation requirements, the flat plate needs to keep a certain distance from the main body casing and the control component. Therefore, the main body of the hot melt binding machine. This solution adjusts the connection relationship between the movable baffle and the main body casing, directly arranges the movable baffle on the outer casing, and the hot melt binding machine only includes the outer casing and the control component in the height direction, changing from a three-layer structure to a two-layer structure, thus thinning the thickness of the main body.

[0010] Preferably, an installation groove is provided on the outer casing and / or the main body; the fixed baffle and the movable baffle are detachably connected to the outer casing and / or the main body through the installation groove.

[0011] During the shipping process, the baffle can be disassembled and laid flat, which not only reduces the space occupied by the whole hot melt binding machine, but also avoids the collision damage of the connection position between the baffle and the heating tank during transportation, reducing the transportation loss while improving the transportation efficiency.

[0012] Preferably, a plurality of limiting portions are provided on the main body, and a plurality of engaging portions are provided on the outer housing. The plurality of engaging portions cooperate with the limiting portions to form a limiting structure for restricting the outer housing from disengaging from the working track.

[0013] Since the heating tank is a high-temperature component and the control box contains important electronic components, to prevent damage caused by user's incorrect operation or personal injury, the movement dimension of the outer housing is restricted in this solution, so that it can only move in the accommodation width direction of the heating tank and cannot disengage.

[0014] Preferably, the outer housing includes a movable side plate located in the heating tank; there is a spacing adapted to the thickness of the document to be bound between the movable side plate and the fixed baffle.

[0015] The movable side plate is arranged in the heating tank area, and its movement range is restricted by the side surface of the control box to prevent the outer housing from disengaging from the main body during the sliding process. At the same time, the movable side plate and the fixed baffle form a clamping structure for the binding part of the document to be bound, ensuring that each paper page is closely attached during binding.

[0016] Preferably, the limiting portions include a plurality of first limiting portions, the engaging portions include a plurality of first engaging portions, and the first limiting portions are arranged on the moving path of the first engaging portions along the working track to form a limiting structure for restricting the moving distance of the outer housing on the working track.

[0017] The first limiting portions are opened on the main body and restrict the sliding of the first engaging portions on the working track; when the first engaging portions do not disengage from the first limiting portions, the outer housing will not disengage from the main body.

[0018] Preferably, the moving distance of the outer housing on the working track is adapted to the accommodation width of the heating tank.

[0019] The moving distance of the outer housing is further restricted. When the outer housing is at the maximum sliding position on the working track, it can just completely expose the accommodation space in the heating tank without further exposing the control box, preventing the heating components or other electronic components in the control box from being exposed and causing potential safety hazards.

[0020] Preferably, an electronic control component area for accommodating electronic components is provided between the plurality of limiting portions.

[0021] In the prior art, the accommodation space for the electronic control components and the chute for adjusting the movable baffle are respectively in different areas inside the main body of the hot melt binding machine, and the space utilization efficiency is relatively low. In this solution, the layout inside the main body of the hot melt binding machine is improved, and the electronic control component area is arranged between the limiting portions, improving the space utilization efficiency inside the main body of the hot melt binding machine and making the volume of the finished hot melt binding machine smaller.

[0022] Preferably, the arrangement direction of multiple groups of the electric control component areas conforms to the length direction of the main machine.

[0023] The hot melt binding machine with a relatively high degree of intelligence includes multiple electric control modules such as digital display, automatic timing, and automatic temperature control. In order to increase the functions of the hot melt binding machine without expanding the volume of the main machine, in this solution, the electric control components are arranged along the length direction of the control box, making full use of the space in the length direction.

[0024] Preferably, an electric control component box is connected to the outer shell body; the electric control component box has a movement track that moves synchronously with the working track, and the starting position of the movement track is accommodated in the electric control component area.

[0025] Preferably, a wiring opening is provided on the electric control component box; the wiring opening is provided on one side close to the heating groove.

[0026] During the working process of the hot melt binding machine, since the electric control panel moves back and forth in the width direction of the equipment along with the outer shell body, the electric control component box below the electric control panel will also move synchronously and partially separate from the control box. In order to protect the electric control components, in this solution, the wiring opening is set on the side of the electric control component box close to the heating groove, and the wiring opening will not be exposed outside the control box during the movement process.

[0027] This solution changes the adjustment method of the movable baffle and optimizes the layout of the main machine of the hot melt binding machine, reducing the packing and transportation volume of the hot melt binding machine from two aspects of width specification and height specification, and saving the logistics cost. In terms of width specification, the prior art is a four-zone design including a heating groove, a movable baffle adjustment chute, a cooling groove, and an electric control panel. In this solution, by fixing the relative positions of the electric control panel and the movable baffle, the main machine is adjusted to a three-zone design of a heating groove, a cooling groove, and an electric control panel. In terms of height specification, the prior art is a three-zone design including a main machine shell, a movable space for the movable baffle adjustment device, and a control box. This solution adjusts the main machine to a two-zone design of an outer shell body and a control box. On this basis, this solution further reasonably plans the internal space of the main machine of the hot melt binding machine, and can improve the intelligence level of the hot melt binding machine without increasing the volume.

Detailed Implementation Manner

[0030] The present invention will be further described below in conjunction with the accompanying drawings of the specification and specific embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention involved in the following description are usually only a part of the embodiments of the present invention, rather than all of the embodiments. Therefore, all other embodiments obtained by those of ordinary skill in the art without creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention. Embodiment

[0031] This embodiment is a hot melt binding machine.

[0032] To achieve the hot melt function, the hot melt binding machine is equipped with a heating groove, and the hot melt adhesive on the document cover to be bound is melted by the heating plate at the bottom of the heating groove. Clamping baffles for fixing the document to be bound are provided on both sides of the heating groove. A cooling groove is provided adjacent to the heating groove for cooling and solidifying the hot melt adhesive after binding.

[0033] To adapt to documents to be bound with different thicknesses, the baffles in the heating area of the hot melt binding machine include movable baffles and fixed baffles. The position of the fixed baffle is fixed relative to the heating groove, while the movable baffle can move back and forth along the width direction of the heating groove, and the document to be bound in the heating groove is stably clamped by the movable baffle and the fixed baffle.

[0034] In the existing structure of a hot melt binding machine, a chute extending along the width direction of the heating groove is provided on the surface of the main body. The movable baffle of the heating groove is connected to the slider through a horizontal connecting plate. The slider is embedded in the chute and exposed outside the main body of the hot melt binding machine. The user adjusts the position of the movable baffle of the heating groove by controlling the movement of the slider in the chute. The surface of the main body of the hot melt binding machine also includes an electronic control panel controlled by the user for interaction. The width dimension of the main body of the hot melt binding machine needs to accommodate at least four partitions, namely, the accommodation width of the heating groove, the length of the chute, the width of the cooling groove, and the width of the electronic control panel. The height dimension of the main body includes at least three partitions, namely, the main body housing, the movable space of the connecting plate, and the accommodation area of the electronic control components. The overall transportation volume is relatively large, and the connection part between the baffle and the main body is prone to damage during transportation, resulting in a relatively high logistics cost.

[0035] In view of this, this embodiment hopes to propose a hot melt binding machine with a smaller packing and transportation volume to save transportation costs.

[0036] Please refer to Figure 1 , the hot melt binding machine includes a main body below and a baffle above. The main body includes a control box 1 for accommodating electronic components and a heat dissipation box 8 below the cooling groove. The control box 1 and the cooling groove are connected by two parallel connecting arms 2. A heating groove 7 is provided in the area enclosed by the side surface of the control box 1, the side surface of the heat dissipation box 8, the inner side plate 210 of the connecting arm 2, and the heating plate 710. The arrangement direction of the connecting arms 2 is the length direction of the main body and the heating groove 7; the extending direction of the connecting arms 2 is the width direction of the main body and the heating groove 7. The length of the inner side plate 210 of the connecting arm 2 is the accommodation width of the heating groove 7, and the accommodation width is adapted to the maximum binding thickness provided by this hot melt binding machine. For example, when the maximum binding thickness provided by the hot melt binding machine is 4 cm, the corresponding accommodation width of the heating groove 7 is 4 cm; when the maximum binding thickness provided by the hot melt binding machine is 5.5 cm, the corresponding accommodation width of the heating groove 7 is 5.5 cm. The baffle includes a movable baffle 620 and a fixed baffle 610. The setting positions of the movable baffle 620 and the fixed baffle 610 are on both sides of the heating groove 7 for clamping the documents to be bound in the heating groove 7; the setting positions of the fixed baffle 610 and the heat dissipation baffle 640 are on both sides of the heat dissipation box 8 for storing the just-bound documents to be cooled. The fixed baffle 610 and the heat dissipation baffle 640 are connected to the heat dissipation box 8 and have a relatively fixed position with respect to the main body.

[0037] For the convenience of describing the legend, hereinafter, the length direction of the heating groove 7 is referred to as the left-right direction, and the side where the switch 9 is located in the figure is the right side; the width direction of the heating groove 7 is referred to as the front-back direction, and the side where the handle 340 is located is the front side.

[0038] Please refer to Figure 1, there is an outer housing 3 outside the main body. The outer housing 3 has a working trajectory that moves back and forth along the accommodation width direction. The outer housing 3 includes a top cover 310 arranged above the control box 1. An electric control panel 330 is provided on the front side of the top cover 310, and a movable baffle 620 is connected to the rear side. When the outer housing 3 moves along the working trajectory, the electric control panel 330 and the movable baffle 620 always maintain a relatively fixed positional relationship. An electric control component box 350 for accommodating electric control components is connected below the electric control panel 330. The electric control component box 350 is also fixed on the outer housing 3 and moves synchronously with the outer housing 3. The movable baffle 620 is arranged on the side of the top cover 310 close to the heating groove 7. When the position of the movable baffle 620 changes, the distance from the fixed baffle 610 also changes, and it can clamp document stacks of different thicknesses to be bound.

[0039] Due to changing the moving mode of the movable baffle 620, the hot melt binding machine proposed in this embodiment does not need to accommodate a chute in the width direction. In the storage state, the main body of the hot melt binding machine in this embodiment only includes three partitions in the width direction, namely the control box 1, the heating groove 7, and the heat dissipation box 8, and only includes two partitions in the height direction, namely the top cover 310 and the control box 1. When packed and transported, it has smaller dimensions in both the width direction and the height direction, occupies less logistics space, and reduces transportation costs.

[0040] To further facilitate transportation, the baffle in this solution is designed to be detachably connected.

[0041] Please refer to Figure 3 、 Figure 5 , a plurality of installation slots 6 are opened in the areas of the top cover 310 and the heat dissipation box 8 close to the heating groove 7. The installation slots 6 on the top cover 310 are used to install the movable baffle 620, and the installation slots 6 on the heat dissipation box 8 are used to install the fixed baffle 610 and the heat dissipation baffle 640. A plurality of installation inserts 630 are provided at the lower ends of the movable baffle 620, the fixed baffle 610, and the heat dissipation baffle 640. The shape of the installation inserts 630 is adapted to the inner contour of the installation slots 6 and can be clamped in the installation slots 6 when installation is required and pulled out from the installation slots 6 when storage is required.

[0042] When transportation is required, the above baffles can be disassembled and laid flat and stacked below the main body, which not only reduces the space occupied by the hot melt binding machine during transportation but also avoids damage to the connection positions between the baffles and the main body during transportation, reducing transportation damage while improving transportation efficiency.

[0043] To facilitate the user to move the outer housing 3, a handle 340 for driving the outer housing 3 to move is provided on the outer housing 3. The handle 340 can be designed at any position on the top cover 310 to best adapt to ergonomics. In this embodiment, the handle 340 is arranged in the central area of the top cover 310 to facilitate uniform force application on all parts of the outer housing 3.

[0044] Since the heating tank 7 is a high-temperature component and the control box 1 contains important electronic components, in order to prevent damage or personal injury caused by user misoperation, this solution limits the movable dimensions of the outer shell 3 so that it can only move in the accommodating width direction of the heating tank 7 and cannot detach.

[0045] See also Figure 5 The host is provided with multiple groups of limiting parts 5, and the outer shell 3 is provided with multiple groups of engaging parts 4. Multiple groups of matching structures A formed by the engaging parts 4 and the limiting parts 5 are formed between the hot melt binding machine host and the outer shell.

[0046] See also Figure 2 The limiting portion 5 includes a plurality of first limiting portions 510, and the engaging portion 4 includes a plurality of first engaging portions 410. The first limiting portions 510 are arranged on the moving path of the first engaging portions 410 along the working trajectory to form a limiting structure for limiting the moving distance of the outer shell 3 on the working trajectory.

[0047] In some embodiments, the first engaging portion 410 is a columnar structure, and the first limiting portion 510 is a sliding groove adapted to the columnar structure. The columnar first engaging portion 410 can only move back and forth within the range limited by the sliding groove of the first limiting portion 510; since the sliding groove is provided on the control box 1, as long as the first engaging portion 410 does not detach from the first limiting portion 510, the outer shell 3 will not detach from the host.

[0048] In a preferred embodiment, under the limitation of the first limit portion 510, the movable range of the outer shell 3 on the working track is the same as the accommodation width of the heating groove 7. At this time, when the outer shell 3 is located at the maximum sliding position on the working track, the accommodation space in the heating groove 7 can be completely exposed without further exposing the control box 1, thereby preventing the heating assembly or other electronic components in the control box 1 from being exposed and causing safety hazards.

[0049] See also Figure 2 , Figure 4 The limiting part 5 includes a plurality of groups of second limiting parts 520, and the clamping part 4 includes a plurality of groups of second clamping parts 420. The second limiting parts 520 and the second clamping parts 420 abut against each other in the length direction of the main machine, and cooperate to form a limiting structure that limits the movement of the outer shell 3 in the length direction. Part of the abutting structure is that the second clamping part 420 is on the left and the second limiting part 520 is on the right, and part of the abutting structure is that the second clamping part 420 is on the right and the second limiting part 520 is on the left. Under the cooperation and guidance of the second clamping part 420 and the first clamping part 410, the outer shell 3 only has a working track that moves forward and backward along the width direction of the heating groove 7.

[0050] In some embodiments, the second engaging portion 420 has a sheet-like structure, and the second limiting portion 520 is a through groove that clamps the sheet-like structure. The extending direction of the through groove conforms to the width direction of the main body. The sheet-like second engaging portion 420 slides in the second limiting portion 520 along the width direction of the main body and cannot sway left and right in the length direction.

[0051] Please refer to Figure 4 , the limiting portion 5 includes multiple groups of third limiting portions 530, and the engaging portion 4 includes multiple groups of third engaging portions 430. The third limiting portion 530 abuts against the first engaging portion 410 in the vertical direction to prevent the outer casing 3 from detaching from the main body in the vertical direction.

[0052] In some embodiments, the third engaging portion 430 has an L-shaped structure with a horizontally extending limiting surface; the third limiting portion 530 is a structure protruding downward from the surface of the main body; the limiting surface of the third engaging portion 430 abuts against the third limiting portion 530 to prevent the user from lifting the outer casing 3 when moving the outer casing 3.

[0053] Please refer to Figure 2 , the outer casing 3 includes a movable side plate 320 located in the heating groove 7, and the movable side plate 320 moves with the outer casing 3. Since the movement range of the movable side plate 320 is limited to the heating groove 7 area between the control box 1 and the heat dissipation box 8, the outer casing 3 will not detach from the main body during the sliding process. In addition, the movable side plate 320 and the side wall of the heat dissipation box 8 form a clamping structure for the binding part of the document to be bound, ensuring that the paper pages are closely attached to each other during binding.

[0054] To further save the volume of the device, the regional layout inside the main body of the hot melt binding machine is optimized in this solution.

[0055] Please refer to Figure 3, the lower surface of the top cover 310 is in close contact with the upper surface of the control box 1, and the gravity of the top cover 310 creates a squeezing force between the two surfaces. When there is a tendency of relative sliding between the two, a pressure is generated on the contact surface, hindering their relative sliding. Under the working state of the device, the pressure exerted by the top cover 310 on the control box 1 is actually the sum of the gravity of the entire outer shell 3 and the gravity of the movable baffle 620. The gravity of this structure is greater than that of the push block structure in the prior art, and the provided frictional force is also greater. This solution makes full use of this high-friction property to enable the movable baffle 620 and the fixed baffle 610 to stably clamp the document to be bound. When the document to be bound is placed in the heating slot 7, the paper pages fall vertically to both sides due to gravity, and when falling, the paper pages have a tendency to push the movable baffle 620 away from the fixed baffle 610; since the fixed baffle 610 moves synchronously with the top cover 310, and there is a large frictional force when the top cover 310 and the control box 1 slide relative to each other, at this time the frictional force will further hinder the movement tendency of the fixed baffle 610. That is to say, the movable baffle 620 will not be pushed by the spread document to be bound and can effectively clamp the document to be bound. On this basis, there is no need to set up a special pressing mechanism inside the main body of the hot melt binding machine to press the document to be bound, saving the volume of the main body.

[0056] Please refer to Figure 4 , an electronic control component area 110 is reserved between the first limiting part 510 and the second limiting part 520 on the left side for arranging electronic components related to time control; an electronic control component area 110 is also reserved between the two second limiting parts 520 for arranging electronic components related to temperature control; multiple electronic control component areas 110 are arranged along the length direction of the main body. Please refer to Figure 2, an electric control component box 350 is connected to the outer shell 3, and the electric control component box 350 moves synchronously with the working trajectory of the outer shell 3. When the hot melt binding machine is in the storage state, the electric control component box 350 is located in the electric control component area 110 between the first limiting part 510 and the second limiting part 520; when the hot melt binding machine is in the working state, the electric control component box 350 moves away from the electric control component area 110 along with the movement of the outer shell 3 and returns to its original position when it needs to be stored. A wiring port 351 is provided on the electric control component box 350, and a wiring area 111 is provided on the control box 1. The connecting wire of the time control electric control component passes through the wiring port 351, passes through the wiring area 111, and then penetrates into the control box 1 to be connected to the temperature control electric control component. The wiring port 351 is provided on the lower surface of the control box 1 on the side close to the heating groove 7. At any position of the working trajectory of the outer shell 3, the wiring port 351 is received in the contact area between the control box 1 and the outer shell 3 and will not be exposed to the outside, playing a role in protecting the connecting wire. In the width direction of the main body of the hot melt binding machine, the areas occupied by the two electric control component areas 110 overlap with the areas occupied by the two limiting parts 5, improving the space utilization efficiency in the control box 1. From the perspective of the finished product of the hot melt binding machine, at this time, the width of the control box 1 only needs to accommodate the working trajectory of the outer shell; when the maximum binding thickness of the hot melt binding machine is 60 mm, the accommodating width of the heating groove is 60 mm, and the length of the working trajectory is also about 60 mm. If the width of the heat dissipation box is the same as that of the heating groove, the width of the main body of the hot melt binding machine only needs to be 180 mm to 200 mm, which is much smaller than the width of more than 240 mm of commercially available products.
